To investigate the presence of different forms of experiences of discrimination in the medical workplace. A total of 526 questionnaires were sent out, including a demographic survey form and the Everyday Discrimination Scale. Experiences of being "treated with less courtesy than other people are" and feeling as "others acted if they're better than [me]" were reported as having occurred with almost daily frequency by 4.1 % of respondents. Those whose main language was not English and classified as "non-whites" had significantly more experiences ("ever") of discrimination in the medical workplace. The most commonly reported reasons for discrimination were ancestry (31.3%), "race" (28.1%), and gender (21.1%). The results of this survey indicate that a proportion of doctors experience discrimination in the workplace in Australia. This phenomenon was more commonly reported by doctors of minority status.

Poomsae is the only non-contact and no opponent form of Taekwondo. The purpose of this descriptive study was to determine the type and rate of injuries in elite Canadian Poomsae athletes. Strain and joint dysfunction were the most common types of injuries in Poomsae. Lower limb and back were the most common area of injury in females and males respectively. Females with a lower rank in experience level (DAN≤ 3) were more likely to suffer from chronic overuse injuries compared to their male counterparts, who reported more acute injuries. Athletes ≤40 years of age were more prone to acute injuries compared to athletes over 40. As result of reflection on this study a Poomsae Injury Report Form was developed. PMID:28065994

Reporter gene assays (RGAs) are commonly used to measure biological pathway modulation by small molecules. Understanding how such compounds interact with the reporter enzyme is critical to accurately interpret RGA results. To improve our understanding of reporter enzymes and to develop optimal RGA systems, we investigated eight reporter enzymes differing in brightness, emission spectrum, stability, and substrate requirements. These included common reporter enzymes such as firefly luciferase (Photinus pyralis), Renilla reniformis luciferase, and β-lactamase, as well as mutated forms of R. reniformis luciferase emitting either blue- or green-shifted luminescence, a red-light emitting form of Luciola cruciata firefly luciferase, a mutated form of Gaussia princeps luciferase, and a proprietary luciferase termed "NanoLuc" derived from the luminescent sea shrimp Oplophorus gracilirostris. To determine hit rates and structure-activity relationships, we screened a collection of 42,460 PubChem compounds at 10 μM using purified enzyme preparations. We then compared hit rates and chemotypes of actives for each enzyme. The hit rates ranged from <0.1% for β-lactamase to as high as 10% for mutated forms of Renilla luciferase. Related luciferases such as Renilla luciferase mutants showed high degrees of inhibitor overlap (40-70%), while unrelated luciferases such as firefly luciferases, Gaussia luciferase, and NanoLuc showed <10% overlap. Examination of representative inhibitors in cell-based assays revealed that inhibitor-based enzyme stabilization can lead to increases in bioluminescent signal for firefly luciferase, Renilla luciferase, and NanoLuc, with shorter half-life reporters showing increased activation responses. From this study we suggest strategies to improve the construction and interpretation of assays employing these reporter enzymes.

2009-01-01

We performed semistructured interviews with 30 family members of patients with advanced dementia to identify the factors that facilitate or hinder advance planning by persons with dementia. All interviews were analyzed using qualitative data analysis techniques. The majority (77%) of family members reported that their relative had some form of written advance directive, and at least half reported previous discussions about health care preferences (57%), living situation or placement issues (50%), and finances or estate planning (60%) with the patient. Family members reported some themes that prompted planning and others that were barriers to planning. Events that most often triggered planning were medical, living situation, or financial issues associated with a friend or family member of the patient (57%). Barriers to planning included both passive and active avoidance. The most common form of passive avoidance was not realizing the importance of planning until it was too late to have the discussion (63%). The most common form of active avoidance was avoiding the discussion (53%). These data suggest potentially remediable strategies to address barriers to advance planning discussions. PMID:18580595

2018-03-15

Fat talk, negative communication about weight, is common in the media, peer groups, and families. Little is known about parental fat talk directed at oneself or others. This study examined associations between different forms of parental fat talk and child disordered eating behaviors and weight, and differences by child sex and age. Parents of preadolescents or adolescents (n = 581) reported fat talk about themselves (self-fat talk), others (obesity-fat talk), and their child (child-fat talk). 76.0% of parents reported regular self-fat talk in front of children, 51.5% reported obesity-fat talk, and 43.6% reported child-fat talk. Fat talk did not differ significantly between parents of preadolescents and adolescents but was more common with sons than daughters. Of the three forms of fat talk, only child-fat talk was associated with all child eating and weight variables (binge eating, overeating, secretive eating, and overweight/obesity); associations were strongest for adolescent girls. Child sex was associated with secretive eating and overweight/obesity. Parents reported using different forms of fat talk frequently. Parent self- and obesity-fat talk were reported more frequently, but child-fat talk was the most strongly associated with children's eating and weight. Because of associations with disordered eating behaviors, intervening to reduce fat talk might contribute to improving pediatric disordered eating and weight-related interventions. © 2018 Wiley Periodicals, Inc.

A Common Bile Duct Stone formed by Suture Material after Open Cholecystectomy

Kim, Kook-Hyun; Jang, Byung-Ik

2007-01-01

The use of non-absorbable suture materials for cystic duct ligation after cholecystectomy can expose patients to the risk of recurrent stone formation in the common bile duct (CBD). However, in Korea suture materials have rarely been found to act as a nidus for common bile duct calculus formation. Recently, we experienced a case in which suture material, that had migrated from a previous cholecystectomy site into the CBD, probably served as a nidus for common bile duct stone formation. The stone was confirmed by endoscopic retrograde cholangiopancreatography (ERCP) and removed successfully using a basket. The authors report a case of surgical suture migration and discuss its subsequent role as a stone forming nucleus within the CBD in a patient who underwent open cholecystectomy; and include a review of the literature.

The field of foot and ankle surgery lacks a widely accepted gold-standard patient-reported outcome instrument. With the changing infrastructure of the medical profession, more efficient patient-reported outcome tools are needed to reduce respondent burden and increase participation while providing consistent and reliable measurement across multiple pathologies and disciplines. The primary purpose of the present study was to validate 3 Patient-Reported Outcomes Measurement Information System computer adaptive tests (CATs) most relevant to the foot and ankle discipline against the Foot and Ankle Outcome Score (FAOS) and the Short Form 12 general health status survey in patients with 6 common foot and ankle pathologies. Patients (n = 240) indicated for operative treatment for 1 of 6 common foot and ankle pathologies completed the CATs, FAOS, and Short Form 12 at their preoperative surgical visits, 1 week subsequently (before surgery), and at 6 months postoperatively. The psychometric properties of the instruments were assessed and compared. The Patient-Reported Outcomes Measurement Information System CATs each took less than 1 minute to complete, whereas the FAOS took 6.5 minutes, and the Short Form 12 took 3 minutes. CAT scores were more normally distributed and had fewer floor and ceiling effects than those on the FAOS, which reached as high as 24%. The CATs were more precise than the FAOS and had similar responsiveness and test-retest reliability. The physical function and mobility CATs correlated strongly with the activities subscale of the FAOS, and the pain interference CAT correlated strongly with the pain subscale of the FAOS. The CATs and FAOS were responsive to changes with operative treatment for 6 common foot and ankle pathologies. The CATs performed as well as or better than the FAOS in all aspects of psychometric validity. The Patient-Reported Outcomes Measurement Information System CATs show tremendous potential for improving the study of patient outcomes in foot and ankle research through improved precision and reduced respondent burden.

2008-08-01

Periventricular nodular heterotopia is a common malformation of cortical development in which the migration of developing neurons destined for the cerebral cortex is abbreviated. Bilateral periventricular nodular heterotopia is most commonly an X-linked disorder that involves mutations in the filamin A (FLNA) gene, but an autosomal recessive form and sporadic forms have been identified. To our knowledge, autosomal dominant transmission of isolated periventricular nodular heterotopia has not been reported. Periventricular nodular heterotopia has a heterogeneous phenotype, associated commonly with seizure disorder, and more recently with reading deficits and visual-spatial deficits in some patients. We present a father and son with bilateral periventricular nodular heterotopia and similar visual-spatial learning deficits, consistent with nonverbal learning disability.

Standardized reporting of functioning information on ICF-based common metrics.

Prodinger, Birgit; Tennant, Alan; Stucki, Gerold

2018-02-01

In clinical practice and research a variety of clinical data collection tools are used to collect information on people's functioning for clinical practice and research and national health information systems. Reporting on ICF-based common metrics enables standardized documentation of functioning information in national health information systems. The objective of this methodological note on applying the ICF in rehabilitation is to demonstrate how to report functioning information collected with a data collection tool on ICF-based common metrics. We first specify the requirements for the standardized reporting of functioning information. Secondly, we introduce the methods needed for transforming functioning data to ICF-based common metrics. Finally, we provide an example. The requirements for standardized reporting are as follows: 1) having a common conceptual framework to enable content comparability between any health information; and 2) a measurement framework so that scores between two or more clinical data collection tools can be directly compared. The methods needed to achieve these requirements are the ICF Linking Rules and the Rasch measurement model. Using data collected incorporating the 36-item Short Form Health Survey (SF-36), the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), and the Stroke Impact Scale 3.0 (SIS 3.0), the application of the standardized reporting based on common metrics is demonstrated. A subset of items from the three tools linked to common chapters of the ICF (d4 Mobility, d5 Self-care and d6 Domestic life), were entered as "super items" into the Rasch model. Good fit was achieved with no residual local dependency and a unidimensional metric. A transformation table allows for comparison between scales, and between a scale and the reporting common metric. Being able to report functioning information collected with commonly used clinical data collection tools with ICF-based common metrics enables clinicians and researchers to continue using their tools while still being able to compare and aggregate the information within and across tools.

2017-01-02

Ecstasy (MDMA) use has regained popularity in the United States, particularly in the form of "Molly," which is often marketed as pure MDMA. Surveys have generally not included "Molly" in the definition of ecstasy, so rates of use may be underestimated. As popularity of ecstasy increases, research is needed to examine use among those at highest risk for use-nightlife attendees. We surveyed 679 young adults (age 18-25) entering nightclubs and festivals holding electronic dance music (EDM) parties in New York City in 2015. A variation of time-space sampling was utilized. We examined prevalence and correlates of self-reported lifetime ecstasy use. Self-reported lifetime ecstasy use was common (42.8%, 95% CI: 32.8, 52.7). Use was most common among older participants, frequent party attendees, and those reporting higher levels of exposure to users. Those surveyed outside of festivals were less likely to report use compared to those surveyed outside of nightclubs (AOR = 0.37, p = .015). Over a third of ecstasy users (36.8%)reported use in pill, powder, and crystal form. Ecstasy users were also more likely to report use of other drugs, including novel psychoactive substances (e.g., 2C series drugs, synthetic cathinones ["bath salts"]). Half (50.4%) reported suspecting (21.9%) or finding out (28.5%) that their ecstasy had ever contained a drug other than MDMA. A large percentage of nightlife attendees in NYC report lifetime ecstasy use. Findings should inform prevention and harm reduction programming. Further research is needed as ecstasy continues to change (e.g., in form, purity, and name).

Webster, Amanda A; Carter, Mark

2013-03-01

One of the most commonly cited rationales for inclusive education is to enable the development of quality relationships with typically developing peers. Relatively few researchers have examined the features of the range of relationships that children with developmental disability form in inclusive school settings. Interviews were conducted with 25 children with developmental disability, aged 5 and 12 years, their 3 closest peers, and parents and teachers to examine 6 types of relationships. Behaviours associated with general friendship and acquaintance were the most commonly reported. Few dyads reported high rates of behaviour associated with special treatment, helping, ignoring, or intimate best friend relationships. The relationships of the majority of dyads were characterised by friendship or acceptance, but evidence of more intimate relationships was limited. An important direction for future research is the examination of ways to encourage more intimate relationships.

Metronidazole is a commonly used antimicrobial worldwide. The most common side effects that have been reported are nausea, vomiting and hypersensitivity reactions. However, neurotoxicity has been reported with the use of metronidazole but rather rare. The most common neurological manifestation is peripheral neuropathy involvement in the form of sensory loss. It is worth mentioning that central neurotoxicity is a rare side effect of metronidazole use but reversible. The manifestations vary from a headache, altered mental status to focal neurological deficits. The diagnosis is mainly by neuroimaging in the setting of acute neurological change in the patient status. Here, we report a case of metronidazole-induced neurotoxicity in a 38-year-old male patient who was admitted with a brain abscess and was started on metronidazole for more than 10 weeks. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

Children with Sexual Behavior Problems: Clinical Characteristics and Relationship to Child Maltreatment.

PubMed

Allen, Brian

2017-04-01

Research examining children with sexual behavior problems (SBP) almost exclusively relies on caregiver reports. The current study, involving a sample of 1112 children drawn from a prospective study, utilizes child self-reports and teacher reports, as well caregiver-reports. First, analyses examined children displaying any SBP; a second set of analyses specifically examined children displaying interpersonal forms of SBP. Caregivers reported greater internalizing, externalizing, and social problems for children with general SBP and/or interpersonal SBP when compared to children without SBP. Caregiver concerns were rarely corroborated by teacher and child reports. Protective services records indicated that SBP was linked to childhood sexual abuse, but sexual abuse occurred in the minority of these cases. Physical abuse was more common among children with interpersonal forms of SBP. The data in the current study suggest the need for multiple reporters when assessing children presenting with SBP and that conventional views of these children may be misleading.

2009-12-01

Rhythmic movement disorder (RMD) refers to a group of stereotyped, repetitive movements involving large muscles, usually occurring prior to the onset of sleep and persisting into sleep. RMD more commonly exhibits only one or two forms of rhythmic movements (RM) in most reported cases. However, multiple RM forms of RMD occurring in a patient in the same night have rarely been reported. In this report, we present the unique case of a 15-year-old boy with RMD affected by multiple forms of RM in the same night, including four known forms (i.e., body rocking, head banging, leg rolling, and rhythmic feet movements) and two new kinds of RM (bilateral rhythmic arm rocking and rhythmic hands movements). Two video-polysomnographic recordings were performed in this patient before starting pharmacologic treatment and after long-term oral clonazepam treatment (1.0mg nightly for 3 months). The characteristics of RMD with multiple RM forms and the effectiveness of clonazepam on the RM episodes and polysomnographic findings observed in our patient are discussed. This report raises the fact that a patient with RMD may present with multiple complex rhythmic movements disrupting sleep, which emphasizes that better understanding of the clinical features of complex rhythmic movements during sleep in primary care settings is essential for early clinical diagnosis and optimal management.

Progress Toward Cancer Data Ecosystems.

One of the recommendations of the Cancer Moonshot Blue Ribbon Panel report from 2016 was the creation of a national cancer data ecosystem. We review some of the approaches for building cancer data ecosystems and some of the progress that has been made. A data commons is the colocation of data with cloud computing infrastructure and commonly used software services, tools, and applications for managing, integrating, analyzing, and sharing data to create an interoperable resource for the research community. We discuss data commons and their potential role in cancer data ecosystems and, in particular, how multiple data commons can interoperate to form part of the foundation for a cancer data ecosystem.

A new method for differentiating adducts of common drinking water DBPs from higher molecular weight DBPs in electrospray ionization-mass spectrometry analysis.

PubMed

Zhai, Hongyan; Zhang, Xiangru

2009-05-01

With the presence of bromide in source waters, numerous brominated disinfection byproducts (DBPs) are formed during chlorination. Many of them are polar/highly polar DBPs and thus hard to be detected by gas chromatography mass spectrometry. Electrospray ionization triple quadrupole mass spectrometry (ESI-MS/MS) is reported to be an effective method in finding polar brominated DBPs by setting precursor ion scans of m/z 79 and 81. But as a soft ionization technique, ESI could form adducts of common DBPs, which may complicate ESI-MS/MS spectra and hinder the efforts in finding new brominated DBPs. In this paper, a new method was developed for differentiating adducts of common DBPs from higher molecular weight DBPs. This method was based on the ESI-MS/MS precursor ion scans of the fragments that correspond to the molecular ions of common DBPs. Adducts of common DBPs were selectively detected in the ESI-MS/MS spectra of a simulated drinking water sample. Moreover, the structures of several new brominated DBPs in the sample were tentatively proposed.

The Premerger Notification Office ("PNO") of the Federal Trade Commission ("FTC"), with the concurrence of the Assistant Attorney General in charge of the Antitrust Division of the Department of Justice ("DOJ"), is adopting a Formal Interpretation of the Hart-Scott-Rodino Act, which requires certain persons planning certain mergers, consolidations, or other acquisitions to report information about the proposed transactions to the FTC and DOJ. The Interpretation concerns the reportability of certain transactions involving a Limited Liability Company ("LLC"), a relatively new form of entity authorized by state statutes. Under the Interpretation, the formation of an LLC will be reportable if it will unite two or more pre-existing businesses under common control. Similarly, acquisitions of existing LLC membership interests will be reportable if they would have the effect of uniting two or more pre-existing businesses under common control.

2016-05-01

No clinical trials are currently available that demonstrate the effects of marijuana on patients with migraine headache; however, the potential effects of cannabinoids on serotonin in the central nervous system indicate that marijuana may be a therapeutic alternative. Thus, the objective of this study was to describe the effects of medical marijuana on the monthly frequency of migraine headache. Retrospective chart review. Two medical marijuana specialty clinics in Colorado. One hundred twenty-one adults with the primary diagnosis of migraine headache who were recommended migraine treatment or prophylaxis with medical marijuana by a physician, between January 2010 and September 2014, and had at least one follow-up visit. The primary outcome was number of migraine headaches per month with medical marijuana use. Secondary outcomes were the type and dose of medical marijuana used, previous and adjunctive migraine therapies, and patient-reported effects. Migraine headache frequency decreased from 10.4 to 4.6 headaches per month (p<0.0001) with the use of medical marijuana. Most patients used more than one form of marijuana and used it daily for prevention of migraine headache. Positive effects were reported in 48 patients (39.7%), with the most common effects reported being prevention of migraine headache with decreased frequency of migraine headache (24 patients [19.8%]) and aborted migraine headache (14 patients [11.6%]). Inhaled forms of marijuana were commonly used for acute migraine treatment and were reported to abort migraine headache. Negative effects were reported in 14 patients (11.6%); the most common effects were somnolence (2 patients [1.7%]) and difficulty controlling the effects of marijuana related to timing and intensity of the dose (2 patients [1.7%]), which were experienced only in patients using edible marijuana. Edible marijuana was also reported to cause more negative effects compared with other forms. The frequency of migraine headache was decreased with medical marijuana use. Prospective studies should be conducted to explore a cause-and-effect relationship and the use of different strains, formulations, and doses of marijuana to better understand the effects of medical marijuana on migraine headache treatment and prophylaxis. © 2016 Pharmacotherapy Publications, Inc.

Collateral Report of Psychopathy: Convergent and Divergent Validity of the Psychopathic Personality Inventory-Short Form

Iyican, Susan; Sommer, Johannah M.; Kini, Sheetal; Babcock, Julia C.

2015-01-01

Psychopathy is a personality syndrome comprised of interpersonal, affective, and behavioral features that has emerged as a correlate of intimate partner violence perpetration. One commonly used self-report measure of psychopathy is the Psychopathic Personality Inventory-Short Form. The current study employed a multi-trait, multi-method approach to test convergent and discriminant validity of the measure in partner-violent couples by comparing males’ self-report of psychopathy to the informant report of their female partner (N = 114). It was hypothesized that the female partner-report of the male’s psychopathy would be highly correlated with the male report of his own psychopathy, thus providing evidence for the construct validity and interrater reliability of the PPI-SF. Analyses found that male and female reports were correlated significantly on the two major factors of the PPI-SF. Furthermore, the female-report explained a significant amount of variance over and above men’s self-report on PAI scales designed to indicate antisocial personality traits. PMID:26213500

2006-01-01

Branding is a form of body art wherein third-degree burns are inflicted on the skin to produce permanent scars. This method of scarification is a common practice among many indigenous cultures and has become exceedingly common in western societies. As with other forms of body art, branding is not a manifestation of a psychiatric disorder but, rather, a method of self-expression. The process can be performed through the use of electrocautery, laser, chemicals, freezing, and hot metal. Complications arising from the procedure include acute infection, transmission of blood-borne pathogens, allergic reactions, and sequelae arising from third-degree burns. In addition, skin branding has been shown to be associated with substance abuse and high-risk behaviors among adolescents. The purpose of this article is to present the following case report and review to familiarize clinicians with this dangerous method of body art.

Rickets in Denmark.

PubMed

Beck-Nielsen, Signe Sparre

2012-02-01

Rickets is a heterogeneous group of diseases of the growing child caused by defect mineralization of bone. Nutritional rickets is caused by deficiency of vitamin D, calcium or both. Several hereditary forms of rickets exist where the disease proceeds into adulthood. Nutritional rickets was common in the past, but by introduction of preventative administration of cod liver oil and vitamin D supplementation, nutritional rickets became a rarity. During the last decades, case reports of nutritional rickets reappear in the industrialized countries. It is the general conception that in the industrialized countries, hereditary rickets is the most prevalent cause of rickets today. However, the incidence of nutritional rickets and the incidence and prevalence of hereditary rickets in Scandinavia are unknown. The most common form of hereditary rickets is hypophosphatemic rickets (HR). The geno- and phenotype among Scandinavian patients have not been characterized. Especially, the disease in adult patients is not well described. Moreover, there are conflicting reports of the benefits of medical treatment throughout childhood, and in addition on gender differences in disease severity.

Emergency airway management is a critical skill for military healthcare providers. Our goal was to describe the Emergency Department (ED) intubations at Brooke Army Medical Center (BAMC) over a 12-month period. Physicians performing endotracheal intubations in the BAMC ED complete data collection forms for each intubation event as part of the National Emergency Airway Registry, including patient demographics, intubation techniques, success and failure rates, adverse events, and patient disposition. We cross-referenced these forms against the numbers of intubation events reported in the ED nursing daily reports to ensure capture of all intubations. Providers completed forms for every intubation within 6 weeks of the procedure. We analyzed data from March 28, 2016, to March 27, 2017. During the study period, providers performed 259 intubations in the BAMC ED. Reasons for intubation were related to trauma for 184 patients (71.0%) and medical conditions for 75 patients (29.0%). Overall, first-attempt success was 83.0%. Emergency medicine residents performed a majority of first attempts (95.0%). Most common devices chosen on first attempt were a video laryngoscope for 143 patients (55.2%) and a direct laryngoscope for 115 patients (44.4%). One patient underwent cricothyrotomy. The 2 most common induction agents were ketamine (59.8%; 95% CI, 55.2%-67.4%) and etomidate (19.3%; 95% CI, 14.7%-24.7%). The most common neuromuscular blocking agents were rocuronium (62.9%; 95% CI, 56.7%-68.8%) and succinylcholine (18.9%; 95% CI, 14.3%-24.2%). In the BAMC ED, emergency intubation most commonly occurred for trauma indications using video laryngoscopy with a high first-pass success.

Pseudoephedrine may cause "pigmenting" fixed drug eruption.

PubMed

Ozkaya, Esen; Elinç-Aslan, Meryem Sevinç

2011-05-01

Fixed drug eruption (FDE) is a distinctive drug eruption characterized by recurrent well-defined lesions in the same location each time the responsible drug is taken. Two different clinical forms have been described: the common classic pigmenting form and the rare nonpigmenting form. Nonpigmenting FDE is mainly characterized by symmetrical large erythematous plaques and the dermal histopathologic reaction pattern. Pseudoephedrine is known as the major inducer of nonpigmenting FDE. Pigmenting FDE from pseudoephedrine has not been reported previously. Here, the first case of pseudoephedrine-induced pigmenting FDE is reported, showing the characteristic features of classic pigmenting FDE such as asymmetry, normal-sized lesions, and the epidermodermal histopathologic reaction pattern. Moreover, a positive occlusive patch-test reaction to pseudoephedrine could be demonstrated on postlesional FDE skin for the first time.

Suspected Legionella-induced perimyocarditis in an adult in the absence of pneumonia: a rare clinical entity.

Burke, Peter T; Shah, Roshni; Thabolingam, Raveend; Saba, Souheil

2009-01-01

Legionella infection can manifest itself in many clinical forms, most commonly as pneumonia, but rarely in the form of myocardial involvement. Legionella with myocardial involvement independent of pneumonia is almost never seen in the adult population and therefore is cited only a handful of times in the medical literature. When reported, Legionella carditis itself typically occurs as an isolated pericarditis with effusion. Cases of isolated Legionella with myocardial involvement, but without associated pneumonia, have been reported among children. To our knowledge, there are no reported cases of Legionella myocarditis and pericarditis presenting concurrently with or without pneumonia, in either an adult or a pediatric population. Herein, we report a rare manifestation of Legionella pneumophila-induced perimyocarditis (strongly suspected, if not incontrovertibly proved) in an adult, in the absence of pneumonia.

Cysticercosis: Hooked by a Hooklet on Fine Needle Aspiration Cytology—A Case Report

PubMed Central

Sawhney, Manav; Agarwal, Shubhra

2013-01-01

Cysticercosis is a systemic parasitic disease caused by the larval form of cestode T. solium. It has a worldwide distribution and is potentially harmful with variable clinical manifestations. The patient most commonly presents with subcutaneous and muscle involvement in the form of nodular lesions. The other most commonly involved sites include eye, brain, bladder wall, and heart. Cysticercosis can be diagnosed on serology, and radiologically but confirmatory diagnosis is based on histopathological examination of the involved tissue biopsy specimen. Fine needle aspiration cytology is a useful low-cost outpatient procedure tool for preoperative diagnosis of cysticercosis and is absolutely essential for diagnosis of the parasitic lesions in a peripheral hospital, one like ours.

2012-01-01

Objective: To address the need for brief, reliable, valid, and standardized quality of life (QOL) assessment applicable across neurologic conditions. Methods: Drawing from larger calibrated item banks, we developed short measures (8–9 items each) of 13 different QOL domains across physical, mental, and social health and evaluated their validity and reliability. Three samples were utilized during short form development: general population (Internet-based, n = 2,113); clinical panel (Internet-based, n = 553); and clinical outpatient (clinic-based, n = 581). All short forms are expressed as T scores with a mean of 50 and SD of 10. Results: Internal consistency (Cronbach α) of the 13 short forms ranged from 0.85 to 0.97. Correlations between short form and full-length item bank scores ranged from 0.88 to 0.99 (0.82–0.96 after removing common items from banks). Online respondents were asked whether they had any of 19 different chronic health conditions, and whether or not those reported conditions interfered with ability to function normally. All short forms, across physical, mental, and social health, were able to separate people who reported no health condition from those who reported 1–2 or 3 or more. In addition, scores on all 13 domains were worse for people who acknowledged being limited by the health conditions they reported, compared to those who reported conditions but were not limited by them. Conclusion: These 13 brief measures of self-reported QOL are reliable and show preliminary evidence of concurrent validity inasmuch as they differentiate people based upon number of reported health conditions and whether those reported conditions impede normal function.

Sarcoidosis is a multisystem inflammatory disorder of unknown cause which can affect any organ system. Autosomal dominant lysozyme amyloidosis is a very rare form of hereditary amyloidosis. The Arg64 variant is extraordinarily rare with each family showing a particular pattern of organ involvement, however while Sicca syndrome, gastrointestinal involvement and renal failure are common, lymph node involvement is very rare. In this case report we describe the first reported case of sarcoidosis in association with hereditary lysozyme amyloidosis.

2017-01-01

The inter- or intramolecular oxidative carboamination of alkynes catalyzed by [py2TiCl2NPh]2 is reported. These multicomponent reactions couple alkenes, alkynes and diazenes to form either α,β-unsaturated imines or α-(iminomethyl)cyclopropanes via a TiII/TiIV redox cycle. Each of these products is formed from a common azatitanacyclohexene intermediate that undergoes either β-H elimination or α,γ-coupling, wherein the selectivity is under substrate control.

2016-02-01

Our goal was to describe the forms of persecution reported by adult refugees in the U.S. and the relationships between persecution and health status among this population. Data were derived from the 2003 New Immigrant Survey, a representative sample of new U.S. lawful permanent residents. Major depression, impairment in daily activities due to pain, poor self-reported health, and declining health were described for refugees who had and had not reported persecution prior to arrival in the U.S. Health status was also examined for refugees who reported different forms of persecution. Half of refugees (46.7 %) in this sample reported that they or an immediate family member had been persecuted. One in three persecuted refugees (31.8 %) reported both incarceration and physical punishment. Major depression, pain-related impairment, poor health, and declining health were twice as common among persecuted refugees than among non persecuted refugees. Notably, despite these adverse experiences, the majority of persecuted refugees did not report poor health outcomes.

Polymorphism of crystalline drugs is a common phenomenon. However, the number of reported polymorphic cocrystals is very limited. In this work, the synthesis and solid-state characterization of a polymorphic cocrystal composed of sulfadimidine (SD) and 4-aminosalicylic acid (4-ASA) is reported for the first time. By liquid-assisted milling, the SD:4-ASA 1:1 form I cocrystal, the structure of which has been previously reported, was formed. By spray drying, a new polymorphic form (form II) of the SD:4-ASA 1:1 cocrystal was discovered which could also be obtained by solvent evaporation from ethanol and acetone. Structure determination of the form II cocrystal was calculated using high-resolution X-ray powder diffraction. The solubility of the SD:4-ASA 1:1 cocrystal was dependent on the pH and predicted by a model established for a two amphoteric component cocrystal. The form I cocrystal was found to be thermodynamically more stable in aqueous solution than form II, which showed transformation to form I. Dissolution studies revealed that the dissolution rate of SD from both cocrystals was enhanced when compared with a physical equimolar mixture and pure SD. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci 104:1385-1398, 2015. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association.

Transurethral removal of a cystic urolith in a mare using a laparoscopic specimen pouch.

Williamson, A J; McKinnon, A O

2017-05-01

Cystic urolithiasis is the most common form of urolithiasis reported in horses. In contrast to the gelding or stallion, clinical disease is less common in the mare and manual removal techniques are possible because of their shorter, wider urethral anatomy. However, these manual removal techniques can be traumatic and are limited by the size of the urolith. This report describes the use of a commercial laparoscopic specimen pouch to remove a cystic urolith in a mare. This approach may allow the extraction of larger uroliths per urethra in the mare, while affording some protection to the mucosa of the bladder neck and urethra. © 2017 Australian Veterinary Association.

Our objective was to examine international similarities and differences in the Dysregulation Profile (DP) of the Child Behavior Checklist (CBCL), Teacher's Report Form (TRF), and Youth Self-Report (YSR) via comparisons of data from many societies. Primary samples were those studied by Rescorla et al. (2012): CBCL: N = 69,866, 42 societies; YSR: N = 38,070, 34 societies; TRF: N = 37,244, 27 societies. Omnicultural Q correlations of items composing the DP (from the Anxious/Depressed, Attention Problems, and Aggressive Behavior syndromes) indicated considerable consistency across diverse societies with respect to which of the DP items tended to receive low, medium, or high ratings, whether ratings were provided by parents (M Q = .70), adolescents (M Q = .72), or teachers (M Q = .68). Omnicultural mean item ratings indicated that, for all 3 forms, the most common items on the DP reflect a mix of problems from all 3 constituent scales. Cross-informant analyses for the CBCL-YSR and CBCL-TRF supported these results. Aggregated DP scores, derived by summing ratings on all DP items, varied significantly by society. Age and gender differences were minor for all 3 forms, but boys scored higher than girls on the TRF. Many societies differing in ethnicity, religion, political/economic system, and geographical region manifested very similar DP scores. The most commonly reported DP problems reflected the mixed symptom picture of the DP, with dysregulation in mood, attention, and aggression. Overall, societies were more similar than different on DP scale scores and item ratings.

Acid deposition, more commonly known as acid rain, occurs when emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) react in the atmosphere with water, oxygen, and oxidants to form various acidic compounds. Prevailing winds transport the acidic compounds hundreds of miles, often across state and national borders. These acidic compounds then fall to earth in either a wet form (rain, snow, and fog) or a dry form (gases, aerosols, and particles). At certain levels, the acidic compounds, including small particles such as sulfates and nitrates, can cause many negative human health and environmental effects.

Versatility of the mouse reversal/set-shifting test: effects of topiramate and sex

Bissonette, Gregory B.; Lande, Michelle D.; Martins, Gabriela J.; Powell, Elizabeth M.

2012-01-01

The ability to learn a rule to guide behavior is crucial for cognition and executive function. However, in a constantly changing environment, flexibility in terms of learning and changing rules is paramount. Research suggests there may be common underlying causes for the similar rule learning impairments observed in many psychiatric disorders. One of these common anatomical manifestations involves deficits to the GABAergic system, particularly in the frontal cerebral cortical regions. Many common anti-epileptic drugs and mood stabilizers activate the GABA system with the reported adverse side effects of cognitive dysfunction. The mouse reversal/set-shifting test was used to evaluate effects in mice given topiramate, which is reported to impair attention in humans. Here we report that in mice topiramate prevents formation of the attentional set, but does not alter reversal learning. Differences in the GABA system are also found in many neuropsychiatric disorders that are more common in males, including schizophrenia and autism. Initial findings with the reversal/set-shifting task excluded female subjects. In this study, female mice tested on the standard reversal/set-shifting task showed similar reversal learning, but were not able to form the attentional set. The behavioral paradigm was modified and when presented with sufficient discrimination tasks, female mice performed the same as male mice, requiring the same number of trials to reach criterion and form the attentional set. The notable difference was that female mice had an extended latency to complete the trials for all discriminations. In summary, the reversal/set-shifting test can be used to screen for cognitive effects of potential therapeutic compounds in both male and female mice. PMID:22677721

Al Ashry, Hamdy A; Kenawy, Mohamed A; Shobrak, Mohammed

2014-04-01

An entomological survey was undertaken for one year to update the mosquito fauna of Asir Region, Kingdom of Saudi Arabia. A total of 31 species of 8 genera were reported of which genus Culex (55%) was the most common. Most of collected larvae (59%) belonged to genus Culex (+ Lutzia) followed by Culiseta (26%), Anopheles (13%) and Aedine spp. (2%). Cx. pipiens (39%) and Cs. longiareolata (26.%) were generally the most abundant of all collected larvae. Of the Anopheles spp., An. dthali was common (40%), of Culex spp., Cx. pipiens was predominating (66%) and of Aedine spp., St. aegypti was predominating (71%). Four species: An. fluviatilis, Cx. mattinglyi, Cx. arbieeni and Cx. mimeticus were new reports in Asir Region and Cx. wigglesworthi recorded for the first time from the kingdom. Larvae were more common in low- and highlands than in the moderately altitude areas. In general all species prefer stagnant water but with the exception of Aedine larvae (altogether), the other species prefer presence of algae, vegetation and shade and absence of turbidity (except Culex spp.). A total of 98 different forms of association were reported of which 9 forms were common. All genera breed year round with peaks of abundance during spring for Anopheles spp. and Culex spp. and during winter for Aedine spp. and Cs. longiareolata. A complete list of mosquito fauna of Asir Region comprising 45 spp. was presented based on the present and previous surveys. The study concluded that the occurrence and prevalence of mosquito species mainly the disease vectors in Asir carry the thread of maintaining and transmission of several mosquito-borne diseases.

Tinnitus has been linked to noise exposure, a common form of which is listening to music as a leisure activity. The relationship between tinnitus and type and duration of music exposure is not well understood. We conducted an internet-based population study that asked participants questions about lifetime music exposure and hearing, and included a hearing test involving speech intelligibility in noise, the High Frequency Digit Triplets Test. 4950 people aged 17-75 years completed all questions and the hearing test. Results were analyzed using multinomial regression models. High exposure to leisure music, hearing difficulty, increasing age and workplace noise exposure were independently associated with increased tinnitus. Three forms of music exposure (pubs/clubs, concerts, personal music players) did not differ in their relationship to tinnitus. More males than females reported tinnitus. The objective measure of speech reception threshold had only a minimal relationship with tinnitus. Self-reported hearing difficulty was more strongly associated with tinnitus, but 76% of people reporting usual or constant tinnitus also reported little or no hearing difficulty. Overall, around 40% of participants of all ages reported never experiencing tinnitus, while 29% reported sometimes, usually or constantly experiencing tinnitus that lasted more than 5 min. Together, the results suggest that tinnitus is much more common than hearing loss, but that there is little association between the two, especially among the younger adults disproportionately sampled in this study.

Li, Lin-feng; Wang, Jing

2002-10-01

Contact hypersensitivity (CHS) in hand dermatitis (HD) was studied by patch testing (PT) 105 consecutive adult HD patients and 361 cases of suspected non-hand allergic contact dermatitis (NHD). The suspected offending agents were also investigated by a questionnaire. Age and sex distribution was no different between the 2 groups. The total positivity rate of PT in the HD group was much lower than in the control group (46.7% versus 63.2%, p < 0.01, chi2-test). The most common allergens in HD were rubber mix(17.1%), p-phenylenediamine (PPD) (14.3%), fragrance mix (9.5%), nickel (9.5%), colophonium (6.7%) and potassium dichromate (2.9%), while those in the control group, in sequence, were nickel (20.5%), rubber mix (16.9%), PPD (14.1%), fragrance mix (12.7%), potassium dichromate (5.5%) and colophonium (5.0%). The positivity rate to nickel was lower in the HD group (9.5% versus 20.5%, p < 0.05, chi2-test), while there was no significant difference for the other allergens. HD was divided arbitrarily into 5 groups: (1) vesicular form, in which fine papules and vesicles can be detected. 65.7% of the HD was vesicular form and 55.1% of them were PT positive; (2) fissured form, in which dry skin with fine fissures or desquamation is seen. 8.6% of the HD was fissured form and 30% of them were PT positive; (3) hyperkeratotic form, in which the lesions are thick, hyperkeratotic plaques - 6.7% of the HD was this form and no positive reaction was found; (4) hand and foot dermatitis (HFD) - 12.4% of HD was HFD and 53.8% of them were PT positive; (5) pompholyx - 6.7% of the patients had pompholyx and one positive result to nickel was detected. The suspected offending agents were reported in only 13 (12.4%) patients. These results suggest that CHS is less common in HD than in NHD and that other factors, such as skin irritation, may play more of a role in HD. Nickel allergy is less common in HD than in NHD. CHS may play a role in more than 1/2 of vesicular form HD, HFD and in some fissured HD also, but is less common in hyperkeratotic HD and pompholyx. Only a small proportion of the HD patients could report the suspected offending agents and PT should be performed in all patients with chronic HD.

Spontaneous Urinary Bladder Leiomyoma in a Rhesus Macaque (Macaca mulatta).

Here we report the case of a urinary bladder leiomyoma in a rhesus macaque. The animal was clinically normal and had a lipoma localized to the stifle. Endovesicular leiomyomas are the most common form of urinary bladder leiomyoma in humans. In contrast, this macaque's tumor exhibited extravesicular localization in the bladder. Urinary bladder leiomyomas account for less than 0.5% of all bladder tumors in humans, with only 250 cases reported in total.

Familial adenomatous polyposis (FAP) is the commonest form of inherited form of CRC. It comprises of about 5% of all the colorectal cancers (CRCs). FAP patients have a family history of CRC that suggests a genetic contribution, common exposures among family members, or a combination of both. This case report gives a glimpse of the phenotypic manifestation of FAP and the underlying molecular mechanism which leads to FAP, in addition it also sheds a light on the management of FAP in early stages of life.

Classification and Reporting of Potentially Proarrhythmic Common Genetic Variation in Long QT Syndrome Genetic Testing.

PubMed

Giudicessi, John R; Roden, Dan M; Wilde, Arthur A M; Ackerman, Michael J

2018-02-06

The acquired and congenital forms of long QT syndrome represent 2 distinct but clinically and genetically intertwined disorders of cardiac repolarization characterized by the shared final common pathway of QT interval prolongation and risk of potentially life-threatening arrhythmias. Over the past 2 decades, our understanding of the spectrum of genetic variation that (1) perturbs the function of cardiac ion channel macromolecular complexes and intracellular calcium-handling proteins, (2) underlies acquired/congenital long QT syndrome susceptibility, and (3) serves as a determinant of QT interval duration in the general population has grown exponentially. In turn, these molecular insights led to the development and increased utilization of clinically impactful genetic testing for congenital long QT syndrome. However, the widespread adoption and potential misinterpretation of the 2015 American College of Medical Genetics and Genomics variant classification and reporting guidelines may have contributed unintentionally to the reduced reporting of common genetic variants, with compelling epidemiological and functional evidence to support a potentially proarrhythmic role in patients with congenital and acquired long QT syndrome. As a result, some genetic testing reports may fail to convey the full extent of a patient's genetic susceptibility for a potentially life-threatening arrhythmia to the ordering healthcare professional. In this white paper, we examine the current classification and reporting (or lack thereof) of potentially proarrhythmic common genetic variants and investigate potential mechanisms to facilitate the reporting of these genetic variants without increasing the risk of diagnostic miscues. © 2018 American Heart Association, Inc.

2017-07-01

The extra-intestinal manifestations of inflammatory bowel disease (IBD) are common and involve other organs or systems for example; urinary system. For this review, we used a variety of sources by searching through Web of Science, PubMed, EMBASE, Scopus and directory of open access journals (DOAJ). Urinary complications may occur in up to 22% of patients and nephrolithiasis or renal/kidney stones have been suggested to be a common manifestation of disease in forms of uric acid, calcium phosphate or calcium oxalate. We performed a meta-analysis on five clinical trials and reported that correlation between IBD and formation of stone in renal system is positive and significant (Fix-effect model; CI: 95%, P <0.001, and randomeffect model; CI: 95%, P = 0.03). Based on the reports of the clinical trials, calcium oxalate is more prevalent in Crohn's disease (CD) than in ulcerative colitis (UC).

Trends in Reported Foodborne Illness in the United States; 1996-2013.

Retrospective review is a key to designing effective food safety measures. The analysis examines trends in the reported incidence of illness due to bacterial pathogens commonly transmitted by food in the United States during 1996-2013 with and without specifying a model form for trend. The findings indicate early declines in reported incidence followed by a period of no significant trend for Campylobacter, Listeria, Shiga toxin-producing Escherichia coli O157, and Yersinia. The results are inconclusive about whether there is no trend or an increasing trend for Salmonella. While Shigella exhibits a continuous decline, Vibrio exhibits a continuous increase. Overall, the findings indicate a lack of evidence for continuous reduction in illness due to bacterial pathogens commonly transmitted by food in the United States during 1996-2013. © 2015 Society for Risk Analysis.

Lafta, Riyadh; Aflouk, Nesreen A; Dhiaa, Saba; Lyles, Emily; Burnham, Gilbert

2016-01-01

Background: The continuing conflict in Iraq has now created an estimated four million internally displaced persons (IDPs). The bulk of recently displaced persons are in Central Iraq, often in insecure and difficult situations. Objective: To determine the health status and health needs of women and children, age 15 and under, among a sample of this IDP population in Kirkuk, Baghdad, and Karbala governorates. Methods: Data were collected from the senior female in 1216 families which contained 3665 children living in 45 makeshift settlements. Findings: The majority of IDPs were living in tents or religious centers. Repeated displacements were common. Kidnappings were reported by 5.2% of families, and 7.9% of families reported a death of a family member during or after displacement. Intentional violence accounted for 72.3% of deaths. Only a third of children in school at the time of displacement continued in school. On average, households had received assistance on 3.2 occasions since displacement, food being the most common form. Access to health services was difficult. Some form of transport was often required. Few women knew where to secure antenatal services and many did not know where childhood immunization services were available. During or after displacement 307 women had delivered or were currently pregnant. Complications of pregnancies were common, with a quarter reporting anemia, and 22.1% experiencing hemorrhage. Both communicable and non-communicable diseases (NCDs) were common in the women and children in the survey. Scabies, diarrhea and lice were common among children. Among women, hypertension accounted for 36.6% of NCDs and type 2 diabetes for 15.9%. Domestic violence directed against women was reported in 17.4% of families and against children in 26.6% Interpretation: Women and children in IDP settlements of Central Iraq experience many vulnerabilities involving their health, education and their environment, in addition to living in physical danger. While some external assistance was received, much more is needed to meet the needs of a displaced population which is unlikely to return home soon. PMID:28966867

Adverse drug reactions of non-opioid and opioid analgesics reported to Croatian national authority from 2007 to 2014.

2017-11-01

Adverse drug reactions (ADRs) are commonly observed in the health services because of system weaknesses and individual errors. Analgesics are widely used and it can be expected that with the increased use one can expect increased number of ADRs of analgesics. The aim of this study was to analyze ADRs of non-opioid and opioid analgesics reported to the Croatian Agency for Medicinal Products and Medical Devices (HALMED) from 2007 to 2014. HALMED provided data on generic drug name, year of the ADR report, type of report, institution, reporting person, patient's age, sex and ADR type. In the analyzed period 796 ADRs of analgesics were reported, of which 367 (46%) were serious ADRs. Number of ADR reports was continuously increasing during the analyzed period. There were 20 analgesics that had ≥5 reports, making 597 (75%) of all ADR reports for analgesics. The most common adverse reaction reports of those 20 analgesics referred to individual drugs (n=16; 80%). Most of the ADR reports were filed by physicians (n=257; 43%), followed by pharmacists (n=252; 42%). Most side effects (n=572; 96%) were reported spontaneously through appropriate forms by patients or health professionals. ADRs were most commonly reported in women (n=352; 59%) and most of them have occurred in adults (n=354; 59%). The most common ADRs of opioid and non-opioid analgesics have been reported on the skin and mucous membranes. Most serious ADRs were result of action of opioid analgesics. Number of ADR reports in Croatia is continuously increasing and a considerable number of them refers to serious ADRs. To keep better track of medications and ADRs it is necessary to educate and encourage health professionals and patients in reporting side effects.

The significance of patient safety and risk management in dentistry has surfaced as dental settings bear delicate procedures carried out by teams utilising numerous devices and tools in complex environments. Our aim is to assess awareness, practice, attitude and perceived barriers of reporting incidents amongst dental clinical supervisors working at dental colleges in Riyadh, Saudi Arabia. The objectives are as follows: (i) Determine if correlations exist between socio-demographic data and supervisors' awareness, practice, attitude and perceived barriers. (ii) Identify most common perceived barriers. An online questionnaire was sent to the 450 clinical supervisors working at five dental colleges of Riyadh. The collected data included items assessing the awareness, practice and attitude of reporting students' incidents along with the perceived barriers. A response rate of (60.1% n = 264 of 450) was established. The majority of the respondents (62.9% n = 166) were aware of the incident reporting policy. Yet, only (35.4% n = 93) of them had completed an incident reporting form before. Most of the participants (90.5% n = 239) agreed on the necessity of reporting student's incidents, but only (67.0% n = 177) agreed on the necessity of reporting well-handled incidents. The possible negative relationship with students was the most agreed on barrier to reporting. This study shows that certain demographics of supervisors had significant relationship with their awareness, attitude, perceived barriers and practice. Awareness of the policy and form was linked to the increase in supervisors' practice, although they tend to report verbally rather than in writing. The possible negative relationship with students was the most common perceived barrier. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Diffuse large B-cell lymphoma is the commonest form of non-Hodgkin lymphoma. Gastro-intestinal tract and bone marrow are common extra-nodal sites of lymphomatous involvement. A 54-year-old woman presented with acute onset epigastric pain. On evaluation, raised serum amylase and radiological features of acute pancreatitis were detected. Gastroscopy revealed thickened folds in distal stomach, which on histopathology revealed large B-cell lymphoma. Subsequently, the patient developed extra-hepatic biliary obstruction due to peripancreatic lymph nodal mass that was relieved with plastic biliary stenting. Subsequent chemotherapy regime directed against lymphoma led to resolution of lymphoma. In this patient , pancreatitis was the initial presentation of primary gastric lymphoma, which has not been commonly reported and therefore should be considered in the etiological workup.

Food Sharing across Borders : First Observation of Intercommunity Meat Sharing by Bonobos at LuiKotale, DRC.

PubMed

Fruth, Barbara; Hohmann, Gottfried

2018-06-01

Evolutionary models consider hunting and food sharing to be milestones that paved the way from primate to human societies. Because fossil evidence is scarce, hominoid primates serve as referential models to assess our common ancestors' capacity in terms of communal use of resources, food sharing, and other forms of cooperation. Whereas chimpanzees form male-male bonds exhibiting resource-defense polygyny with intolerance and aggression toward nonresidents, bonobos form male-female and female-female bonds resulting in relaxed relations with neighboring groups. Here we report the first known case of meat sharing between members of two bonobo communities, revealing a new dimension of social tolerance in this species. This observation testifies to the behavioral plasticity that exists in the two Pan species and contributes to scenarios concerning the traits of the last common ancestor of Pan and Homo. It also contributes to the discussion of physiological triggers of in-group/out-group behavior and allows reconsideration of the emergence of social norms in prehuman societies.

Familial polythelia without associated anomalies.

PubMed

Casey, H D; Chasan, P E; Chick, L R

1996-01-01

Of the many forms of supernumerary breast tissue, the most common form is the isolated presence of an accessory nipple, polythelia. While familial polythelia is recognized, it is extremely rare. In the past several years, polythelia has been noted to be associated with nephrourological anomalies. All reports of such a relationship are in random, nonfamilial cases of polythelia. We report three cases of polythelia in a family over two generations who had no urinary tract abnormalities. Discussion includes a comprehensive review of familial polythelia and its association with renal anomalies. From this review, the association of familial polythelia with nephrourological abnormalities will be delineated. Although in this report of a single family with polythelia we did not demonstrate any renal anomalies, we feel that a thorough physical exam, urine analysis, and renal ultrasound should be pursued in any patient with a significant familial history of polythelia.

Following the discovery of glial fibrillary acidic protein (GFAP) mutations as the causative factor of Alexander disease (AxD), new case reports have recently increased, prompting a more detailed comprehension of the clinical features of the three disease subtypes (infantile, juvenile and adult). While the clinical pattern of the infantile form has been substantially confirmed, the late-onset subtypes (i.e., juvenile and adult), once considered rare manifestations of AxD, have displayed a wider clinical spectrum. Our aim was to evaluate the clinical phenotype of the adult and juvenile forms by reviewing the previously reported cases. Data were collected from previously published reports on 112 subjects affected by neuropathologically or genetically proven adult and juvenile Alexander disease. Although the late-onset forms of AxD show a wide clinical variability, a common pattern emerges from comparing previously reported cases, characterized by pseudo-bulbar signs, ataxia, and spasticity, associated with atrophy of the medulla and upper cervical cord on neuroimaging. Late-onset AxD cases can no longer be considered as rare manifestations of the disease. The clinical pattern usually reflects the topographic localization of the lesions, with adult cases displaying a predominant infratentorial localization of the lesions. Juvenile cases show clinical and radiological features which are intermediate between adult and infantile forms.

Diprosopus (partially duplicated head) associated with anencephaly: a case report.

PubMed

al Muti Zaitoun, A; Chang, J; Booker, M

1999-01-01

Craniofacial duplication (diprosopus) is a rare form of conjoined twin. A 16 year old mother with a twin pregnancy delivered one normally formed baby boy and one diprosopus male. The malformed baby was 33 weeks of gestation with a single trunk, normal limbs and various degrees of facial duplication. Of the following structures there were two of each: noses, eyes, ears (and one dimple), mouths, tongues and, with bilateral central cleft lips and cleft palates. This was associated with holoprosencephaly and craniorachischisis. Internal organs showed no duplication. There were multiple congenital anomalies including diaphragmatic hernia, small lungs, two lobes of the right lung, ventricular septal defect, small adrenal gland and small left kidney with short ureter. The body also had a short neck, small chest cavities and kyphosis. X-ray revealed duplication of the vertebral column. The case presented here represents a type II of diprosopia of Rating (1933) and is the least common type reported. We also reviewed 22 recently reported cases of diprosopus. In addition to facial duplication, anencephaly, neural tube defect and cardiac malformations represent the more common congenital abnormalities associated with diprosopus. The pathogenesis of diprosopus is not well understood. Factors that play a role in diprosopus are probably similar to those factors (genetic, environmental and abnormal placental circulation) which affect monozoygotic twins as observed in this case report. Early ultrasonography diagnosis of diprosopus permits one to consider a vaginal therapeutic abortion.

Clinical Scenario: CrossFit is a form of exercise that incorporates rapid and successive high-intensity ballistic movements. As CrossFit is an increasingly popular fitness option, it is important to determine how rates of injury compare to more traditional forms of exercise. This review was conducted to ascertain the incidence of injury with CrossFit relative to other forms of exercise. Focused Clinical Question: Are injuries more common with CrossFit training than other forms of exercise? Summary of Key Findings: (1) The literature was searched for studies that compared injury rates among individuals who participated in CrossFit fitness programs to participants in other exercise programs. (2) The search initially yielded >100 results, which were narrowed down to 3 level 2b retrospective cohort studies that were deemed to have met inclusion/exclusion criteria. (3) In all 3 reviewed studies, the reported incidences of injuries associated with CrossFit training programs were comparable or lower than rates of injury in Olympic weightlifting, distance running, track and field, rugby, or gymnastics. Clinical Bottom Line: Current evidence suggests that the injury risk from CrossFit training is comparable to Olympic weightlifting, distance running, track and field, rugby, football, ice hockey, soccer, or gymnastics. Injuries to the shoulder(s) appear to be somewhat common with CrossFit. However, the certitude of these conclusions is questionable given the lack of randomization, control, or uniform training in the reviewed studies. Clinicians should be aware that injury is more prevalent in cases where supervision is not always available to athletes. This is more often the case for male participants who may not actively seek supervision during CrossFit exercise. Strength of Recommendation: Level 2b evidence from 3 retrospective cohort studies indicates that the risk of injury from participation in CrossFit is comparable to or lower than some common forms of exercise or strength training.

Transparent indium-tin oxide/indium-gallium-zinc oxide Schottky diodes formed by gradient oxygen doping

Amorphous InGaZnO (a-IGZO) is promising for transparent electronics due to its high carrier mobility and optical transparency. However, most metal/a-IGZO junctions are ohmic due to the Fermi-level pinning at the interface, restricting their device applications. Here, we report that indium-tin oxide/a-IGZO Schottky diodes can be formed by gradient oxygen doping in the a-IGZO layer that would otherwise form an ohmic contact. Making use of back-to-back a-IGZO Schottky junctions, a transparent IGZO permeable metal-base transistor is also demonstrated with a high common-base gain.

Information and Communication Technology (ICT) opens up new possibilities for introducing innovative teaching and learning methods to deliver education in different educational areas. Use of internet and social media has grown rapidly and is a key way in how nurses and nurse educator students find information. However, the evidence is still lacking how nurse educator students use social media. The aim of this study is to describe nurse educator students' use of social media and the ways in which their educational needs are related to social media. The data were collected using a structured questionnaire that included one open question. Altogether, 49 nurse educator students completed and returned the questionnaire (response rate 96%). The quantitative data were analysed using statistical programme SPPS and content analysis. While many nurse educator students reported using the tools of social media, others claimed that they do not use social media at all. Facebook was most common (53% use it every day) and YouTube (17%) the second most common form of social media used to support daily living. The participants reported using YouTube (6% use it every day) and Facebook (4%) most often as support in their studies. They reported using Second life as virtual reality form of social media, the least. The most common educational needs of nurse educator students include receiving more in-depth information about how to use social media, as well as more practice in using it. In the future, the education of the nurse educator students should include even more in-depth information about the forms of social media and about the advantages of using it in teaching. The education should encourage nurse educator students and provide them with more possibilities to train and make use of the benefits of social media as support in their daily lives and studies. There is need for more robust evidence of social media use in nurse educator students education.

Hines, Jonas Z; Fiala, Steven C; Hedberg, Katrina

2017-06-16

During 2011-2015, increased electronic cigarette (e-cigarette) and hookah use offset declines in cigarette and other tobacco product use among youths (persons aged <18 years) (1). Limited information exists about which tobacco product introduced youths to tobacco product use. Patterns of first use of e-cigarettes among Oregon youths who were tobacco users were assessed in the Oregon Healthy Teens 2015 survey, a cross-sectional survey of eighth and 11th grade students in Oregon. Respondents were asked, "The very first time you used any tobacco or vaping product, which type of product did you use?" Among students who had ever used any tobacco product (ever users), e-cigarettes were the most common introductory tobacco product reported by both eighth (43.5%) and 11th (34.4%) grade students. Among students who used a tobacco product for ≥1 day during the past 30 days (current users), e-cigarettes were the most common introductory tobacco product reported by eighth grade students (44.4%) and the second most common introductory tobacco product reported by 11th grade students (31.0%). Introductory use of e-cigarettes was commonly reported among youths in Oregon who were ever or current tobacco users, underscoring the importance of proven interventions to prevent all forms of tobacco use among youths (2,3).

Duchenne and Becker Muscular Dystrophy (DMD and BMD, respectively), are common forms of inherited muscle disease. Information regarding the epidemiology of these conditions, including genotype, is still sparse. To establish the prevalence and genetic profile of DMD and BMD in Puerto Rico. We collected data from medical records in all Muscular Dystrophy Association (MDA) clinics in Puerto Rico in order to estimate the prevalence of DMD and BMD and to describe the genotypic profile of these patients. Patients selected for data analysis matched "definite", "probable" and "possible" case definitions as established by MD STARnet. A total of 141 patients matched the inclusion criteria, with 64.5% and 35.5% being categorized into DMD and BMD, respectively. DMD and BMD prevalence in Puerto Rico was estimated at 5.18 and 2.84 per 100,000 males, respectively. Deletion was the most common form of mutation (66.7%) in the dystrophin gene, with exons in segment 45 to 47 being the most frequently affected. This is the first report of the prevalence and genetic profile characteristics of DMD and BMD in Puerto Rico. Prevalence of DMD was similar to that reported worldwide, while prevalence of BMD was higher. Genetic profile was consistent with that reported in the literature.

Heat stress disorders and headache: a case of new daily persistent headache secondary to heat stroke.

Headache is considered as a common symptom of heat stress disorders (HSD), but no forms of secondary headache from heat exposure are reported in the International Classification of Headache Disorders-2 Edition (ICHD-II). Heat-stroke (HS) is the HSD most severe condition, it may be divided into two forms: classic (due to a long period environmental heat exposure) and exertional (a severe condition caused by strenuous physical exercises in heat environmental conditions). Here we report the case of a patient who developed a headache clinical picture fulfilling the diagnostic criteria for new daily persistent headache (NDPH), after an exertional HS, and discuss about possible pathophysiological mechanisms and classification aspects of headache induced by heat conditions.

A novel interference behaviour: invasive wasps remove ants from resources and drop them from a height

PubMed Central

Grangier, Julien; Lester, Philip J.

2011-01-01

This study reports a novel form of interference behaviour between the invasive wasp Vespula vulgaris and the New Zealand native ant Prolasius advenus. By videotaping interactions at bait stations, we found that wasps commonly remove ant competitors from food resources by picking up the workers in their mandibles, flying backward and dropping them unharmed some distance from the food. Both the frequency and the efficiency of the wasp behaviour significantly increased with the abundance of ant competitors. Ant removals were the most common interference events initiated by wasps when ants were numerous, while intraspecific conflicts among wasps were prominent when few ants were present. The ‘ant-dropping’ behaviour emphasizes how asymmetry in body sizes between competitors can lead to a pronounced form of interference, related to asymmetric locomotion modes. PMID:21450726

Assessing the Prevalence of Traumatic Head Injury amongst Recreational Surfers in the United States.

Swinney, Christian

2015-12-01

Surfing is a popular recreational sport that carries a substantial risk of injury. Although head injuries are frequently documented in the surfing population, an in depth assessment of the prevalence of surfing-related head injury has not been reported. A web-based survey was conducted in May of 2015. Participants were asked a series of questions regarding surfing-related injuries and demographic characteristics. A total of 50 responses were obtained, of which 35 (70%) reported sustaining a head injury. The most common injury was laceration of the head/face (n=27), followed by concussion (n=13). Other injuries, such as skull fracture and broken nose, were also reported. Only 2 of the 50 participants reported wearing a protective helmet. Neurosurgical intervention was required in 2 instances. Increased emphasis on preventative measures by the medical community may reduce the future incidence of such injuries. Medical professionals should be aware of the most common forms of injury sustained by the surfing population in order to better recognize and treat these conditions.

A Tale of Two Cysts: Steatocystoma Multiplex and Eruptive Vellus Hair Cysts-Two Case Reports and a Review of the Literature.

PubMed

Waldemer-Streyer, Rachel J; Jacobsen, Ellen

2017-01-01

Background . Steatocystoma multiplex (SM) and eruptive vellus hair cysts (EVHC) are uncommon benign tumors of the pilosebaceous unit. Both SM and EVHC are characterized by smooth, asymptomatic papules or nodules, most commonly presenting on the chest, limbs, and abdomen. Most cases of SM and EVHC are sporadic, although less common autosomal dominant inherited forms have been reported. Main Observation . In this report we present two cases of cutaneous cysts exhibiting characteristics of either SM or EVHC. Both patients presented with numerous 1-2 mm asymptomatic papules and responded well to surgical expression by incision and drainage (I&D). Conclusion . SM and EVHC are similar in clinical presentation and management. Previously reported "hybrid-type" tumors present strong evidence for a relationship between the two lesions pathologically. Due to potential similarity of EVHC and SM cyst contents, I&D and subsequent microscopic examination cannot definitely differentiate between EVHC, SM, and hybrid cysts.

We report an interesting case of a 19 year old female with findings on MRI suggestive of viral encephalitis. An extensive workup was negative for infectious causes and she was subsequently diagnosed with anti-NMDA encephalitis. Anti-NMDA encephalitis is a highly lethal but treatable form of autoimmune encephalitis that has recently been characterized. It is frequently found in young women and associated with an underlying teratoma. Although rare, this diagnosis should be considered in young females for whom a rapid onset of encephalitis cannot be explained by more common causes. PMID:25426239

2014-01-01

Solar elastosis is a degenerative condition of elastic tissue in the dermis due to prolonged sun exposure. There are a variety of clinical manifestations of solar elastosis. In its most common form, solar elastosis manifests as yellow, thickened, coarsely wrinkled skin. We report two uncommon cases of severe solar elastosis with a papular morphology. Its presentation can closely mimic a host of cutaneous disorders and thus, although it is helpful to be cognizant of this entity, it is still crucial to biopsy these lesions to avoid missing a more sinister condition.

Heteropagus twins, also called parasitic twins, are malformation of the foetus where the development of one twin is incomplete. They are attached most commonly to the lower chest and upper abdomen. We report a case of heteropagus twin, where the parasite possessed well-formed limb as well as blind ending intestine. It was attached to the back of the host by a broad pedicle. We take this opportunity to classify areas of confusion prevailing regarding twinning, foetus in foetu, teratoma and caudal duplication.

Naphthalene (C10H8) is a natural component of fossil fuels such as petroleum, diesel and coal. The common consumer products made from naphthalene are moth repellents, in the form of mothballs or crystals, and toilet deodorant blocks. Major toxic effects of naphthalene are due to precipitation of acute intravascular hemolysis. Very few cases of naphthalene poisoning and its effects have been reported from India. We report a case of accidental naphthalene poisoning, who presented with intravascular hemolysis and methemoglobinemia.

Better designs and instrumentation improve glycol dehydrator performance. This paper reports on these guidelines which emphasize efficient water removal from natural gas. Water, a common contaminant in natural gas, causes operational problems when it forms hydrates and deposits on solid surfaces. Result: plugged valves, meters, instruments and even pipelines. Simple rules resolve these problems and reduce downtime and maintenance costs.

Stevens, Courtney J.; Smith, Jane Ellen; Bryan, Angela D.

2015-01-01

Objective To test the extent to which participants exposed to an uncommon versus common exercise stimulus would result in more favourable affect at post task. Design Experimental design. Participants, (N = 120) American women aged 18–45 years, were randomly assigned to complete 30-minutes of either the uncommon (HOOP; n = 58) or common (WALK; n = 62) exercise stimulus. Main Outcome Measures Self-reported affect and intentions for future exercise were measured before and after the 30-minute exercise bout. Results Analyses of covariance (ANCOVA) were run to compare post-task affect across the HOOP and WALK conditions. At post-task, participants assigned to HOOP reported more positively valenced affect, higher ratings of positive activated affect, lower ratings of negative deactivated affect, and stronger intentions for future aerobic exercise compared to participants assigned to WALK. Conclusions Participants who completed an uncommon bout of aerobic exercise (HOOP) reported more favourable affect post-exercise, as well as stronger intentions for future exercise, compared to participants who completed a common bout of aerobic exercise (WALK). Future work using a longitudinal design is needed to understand the relationships between familiarity with an exercise stimulus, affective responses to exercise, motivation for future exercise behaviour, and exercise maintenance over time.

After-hours telephone communications are common in patient management. Patterns of communication of key information during after-hours phone calls were evaluated, and the utility of problem-specific Situation, Background, Assessment, Recommendation (SBAR) forms in improving this communication was assessed. In a randomized trial using a simulated on-call setting, 20 nurses called physicians regarding six cases adapted from inpatient records and based on the six most common reasons for after-hours nurse-physician communication. Three of the cases were handled without the SBAR forms (control cases), and three cases were handled with the forms (SBAR cases). Two cue types of communication were evaluated: situation cues, which conveyed the patient's situation (for example, a patient is confused), and background cues, which conveyed problem-specific data indicated on the SBAR forms (for example, the patient has a low sodium level). Ninety-two phone calls were analyzed (43 SBAR/49 controls). Most of the nurses reported the situation cues (SBAR 88%, control 84%, p = .60) but not the background cues. There was a trend toward fewer background cues communicated in the SBAR cases (14% versus 31%, p = .08). In 14% of the cases, on average, nurses omitted information or reported wrong information regarding the background cue. Physicians asked questions that resulted in the communication of the cues in a minority of the cases when the background cues were not originally provided by the nurses (SBAR 6%, control 16%, p = .39). In after-hours phone communication between physicians and nurses, significant information was often not communicated and physicians did not elicit the necessary information. Simply providing an SBAR-based form did not ensure complete communication of key information.

Occurrence and significance of stalactites within the epithermal deposits at Creede, Colorado

USGS Publications Warehouse

Campbell, W.R.; Barton, P.B.

1996-01-01

In addition to the common and abundant features in karst terranes, stalactites involving a wide variety of minerals have also been found in other settings, including epigenetic mineral deposits, but these are almost always associated with supergene stages. Here we describe a different mode of occurrence from the Creede epithermal ore deposits, in Colorado, wherein stalactites of silica, sphalerite, galena, or pyrite formed in a vapor-dominated setting, below the paleo-water table, and except possibly for pyrite, as part of the hypogene mineralization. Axial cavities may, or may not, be present. No stalagmites have been recognized. The stalactites are small, from a few millimeters to a few centimeters long and a few millimeters in outer diameter. They represent only a small fraction of one percent of the total mineralization, and are covered by later crystals. Their growth orientation usually is unobservable; however, the parallel arrangement of all stalactites in a given specimen, consistency with indicators of gravitational settling, and the common presence of axial structures make the stalactitic interpretation almost unavoidable. In contrast with common carbonate stalactites, the growth mechanism for the sulfide and silica stalactites requires extensive evaporation. Stalactitic forms have also been reported from other deposits, mostly epithermal or Mississippi-Valley-type occurrences, but we caution that stalactite-like features can form by alternative processes.

Healthcare workers particularly doctors are at high risk of being victims of verbal and physical violence perpetrated by patients or their relatives. There is a paucity of studies on work-related violence against doctors in India. We aimed to assess the exposure of workplace violence among doctors, its consequences among those who experienced it and its perceived risk factors. This study was done among doctors working in a tertiary care hospital in Delhi. Data were collected by using a self-administered questionnaire containing items for assessment of workplace violence against doctors, its consequences among those who were assaulted, reporting mechanisms and perceived risk factors. Of the 169 respondents, 104 (61.4%) were men. The mean (SD) age of the study group was 28.6 (4.2) years. Sixty-nine doctors (40.8%) reported being exposed to violence at their workplace in the past 12 months. However, there was no gender-wise difference in the exposure to violence (p=0.86). The point of delivery of emergency services was reported as the most common place for experiencing violence. Verbal abuse was the most common form of violence reported (n=52; 75.4%). Anger, frustration and irritability were the most common symptoms experienced by the doctors who were subjected to violence at the workplace. Only 44.2% of doctors reported the event to the authorities. 'Poor communication skills' was considered to be the most common physician factor responsible for workplace violence against doctors. A large proportion of doctors are victims of violence by their patients or relatives. Violence is being under-reported. There is a need to encourage reporting of violence and prepare healthcare facilities to tackle this emerging issue for the safety of physicians.

Obstructive sleep apnoea is the most common form of sleep-disordered breathing in adults and children. It is associated with many adverse health consequences. The objectives this study were to determine the prevalence, awareness and reporting of symptoms of obstructive sleep apnoea among hospitalized adult patients in Nigeria. This was a multicenter cross-sectional study involving 1420 adult patients admitted to general medical and surgical wards of selected hospitals from March to April 2013. A questionnaire embedded with Berlin questionnaire, Epworth sleepiness scale and questions on level of awareness and reporting of symptoms of sleep apnoea was used for data collection. One-third of the patients (33.4%) reported snoring, 16.3% had excessive daytime sleepiness, 10.0% experienced daytime fatigue, and 8.0% experienced drowsy driving. Approximately 5% reported witnessed apnoea and 18.0% had high risks for obstructive sleep apnoea. The frequency of high risk for sleep apnoea increased with age and declined after 65 years and also increased with the body mass index. Snoring, excessive daytime sleepiness and high risk for obstructive sleep apnoea were more common in patients with chronic medical conditions and who were admitted to the urban hospitals. The majority were not aware that snoring (77.3%) and excessive daytime sleepiness (65.8%) constitute a medical problem, and only 4.5% reported these symptoms to their doctors. The level of awareness and under-reporting of sleep apnoea symptoms are poor. The high prevalence of obstructive sleep apnoea symptoms from this study should form the basis for screening hospitalized patients with chronic medical condition across the country.

2011-01-01

Marijuana is a currently illegal psychoactive drug that many physicians believe has substantial therapeutic uses. The medical literature contains a growing number of studies on cannabinoids as well as case studies and anecdotal reports suggesting therapeutic potential. Fifteen states have passed medical marijuana laws, but little is known about the growing population of patients who use marijuana medicinally. This article reports on a sample of 1,746 patients from a network of nine medical marijuana evaluation clinics in California. Patients completed a standardized medical history form; evaluating physicians completed standardized evaluation forms. From this data we describe patient characteristics, self-reported presenting symptoms, physician evaluations, other treatments tried, other drug use, and medical marijuana use practices. Pain, insomnia, and anxiety were the most common conditions for which evaluating physicians recommended medical marijuana. Shifts in the medical marijuana patient population over time, the need for further research, and the issue of diversion are discussed.

Anatomical variations of the digestive system arteries are important due to their clinical significance. However, anomalies in the inferior mesenteric artery (IMA) are the least common compared with the celiac trunk and superior mesenteric artery. This report describes the case of a 67-year-old man with an extremely rare variant in which the IMA arises from the left common iliac artery, and the ipsilateral external iliac artery has a corkscrew pattern. These findings were depicted during computed tomography angiography of the abdomen and pelvis. This case is the first report of such a variation associated with a left external iliac artery turning into a double loop before forming the femoral artery. The embryological and clinical significance of such an anomaly are discussed.

Reported cases of child maltreatment are increasing in Taiwan. Yet, comprehensive epidemiological characteristics of adolescents' exposure over the wide spectrum of violence are still lacking. The purpose of this study was to estimate the prevalence and magnitude of child maltreatment among Taiwanese adolescents. A population-based study was conducted with 5,276 adolescents aged 12-18 from 35 schools in 17 cities and townships to determine the prevalence of five forms of child maltreatment in Taiwan. A total of 5,236 adolescents completed anonymous, self-report, structured questionnaires. Most adolescents (91%, n=4,788) experienced at least one form of maltreatment with 83% (n=4,347) exposed during the previous year. Violence exposure was the most common type of child maltreatment experienced, followed by psychological abuse, physical abuse, neglect, and sexual abuse. Adolescents reported an average of 7.4 (SD=5.87) victimizations over their lifetime and 4.8 (SD=4.82) victimizations during the past year. Females reported a higher rate of neglect, while males reported a higher rate of sexual abuse. Most of the sexual abuse perpetrators were known by their victims. Adolescents' victimization and polyvictimization from child maltreatment in Taiwan deserves a review and modification of national control and prevention policies. Copyright © 2014 The Authors.

The United States (US) Army implemented a comprehensive HIV characterization program in 2012 following repeal of the Don't Ask, Don't Tell policy banning openly homosexual individuals from serving in the US military. Program staff administered a standardized case report form to soldiers newly diagnosed with HIV from 2012 to 2014 in compliance with new program requirements. The case report form documented sociodemographic, sexual, and other risk behavior information elicited from US Army regulation-mandated epidemiologic interviews at initial HIV notification. A majority of HIV-infected soldiers were male and of black/African American racial origin. In the HIV risk period, male soldiers commonly reported male-male sexual contact, civilian partners, online partner-seeking, unprotected anal sex, and expressed surprise at having a positive HIV result. Don't Ask, Don't Tell repeal allows for risk screening and reduction interventions targeting a newly identifiable risk category in the US Army. At-risk populations need to be identified and assessed for possible unmet health needs.

Abstract: The United States (US) Army implemented a comprehensive HIV characterization program in 2012 following repeal of the Don't Ask, Don't Tell policy banning openly homosexual individuals from serving in the US military. Program staff administered a standardized case report form to soldiers newly diagnosed with HIV from 2012 to 2014 in compliance with new program requirements. The case report form documented sociodemographic, sexual, and other risk behavior information elicited from US Army regulation-mandated epidemiologic interviews at initial HIV notification. A majority of HIV-infected soldiers were male and of black/African American racial origin. In the HIV risk period, male soldiers commonly reported male–male sexual contact, civilian partners, online partner-seeking, unprotected anal sex, and expressed surprise at having a positive HIV result. Don't Ask, Don't Tell repeal allows for risk screening and reduction interventions targeting a newly identifiable risk category in the US Army.

Complementary and alternative medicine (CAM) is recognized to be commonly used by patients, yet there have been few studies regarding the scope of CAM use by patients with epilepsy. This study assessed usage and perceptions of CAM by patients with epilepsy in the midwest of the United States. A 25-item survey was administered to adult patients with epilepsy, and data were collected from 228 patients. The survey collected demographics, specific CAM usage, adverse effects of CAM therapy, and perceptions of the effectiveness of CAM. Thirty-nine percent reported using CAM; 25% reported using CAM specifically for their epilepsy. Prayer/spirituality was the most commonly used form of CAM (46%), followed by "mega" vitamins (25%), chiropractic care (24%), and stress management (16%). CAM use is common among midwestern patients with epilepsy, although the pattern of use may be slightly different than in other regions of the United States and elsewhere.

Dynamical Characteristics Common to Neuronal Competition Models

2009-01-01

Models implementing neuronal competition by reciprocally inhibitory populations are widely used to characterize bistable phenomena such as binocular rivalry. We find common dynamical behavior in several models of this general type, which differ in their architecture in the form of their gain functions, and in how they implement the slow process that underlies alternating dominance. We focus on examining the effect of the input strength on the rate (and existence) of oscillations. In spite of their differences, all considered models possess similar qualitative features, some of which we report here for the first time. Experimentally, dominance durations have been reported to decrease monotonically with increasing stimulus strength (such as Levelt's “Proposition IV”). The models predict this behavior; however, they also predict that at a lower range of input strength dominance durations increase with increasing stimulus strength. The nonmonotonic dependency of duration on stimulus strength is common to both deterministic and stochastic models. We conclude that additional experimental tests of Levelt's Proposition IV are needed to reconcile models and perception. PMID:17065254

The conduct of oral food challenges as the preferred diagnostic standard for food allergy (FA) was harmonized over the last years. However, documentation and interpretation of challenge results, particularly in research settings, are not sufficiently standardized to allow valid comparisons between studies. Our aim was to develop a diagnostic toolbox to capture and report clinical observations in double-blind placebo-controlled food challenges (DBPCFC). A group of experienced allergists, paediatricians, dieticians, epidemiologists and data managers developed generic case report forms and standard operating procedures for DBPCFCs and piloted them in three clinical centres. The follow-up of the EuroPrevall/iFAAM birth cohort and other iFAAM work packages applied these methods. A set of newly developed questionnaire or interview items capture the history of FA. Together with sensitization status, this forms the basis for the decision to perform a DBPCFC, following a standardized decision algorithm. A generic form including details about severity and timing captures signs and symptoms observed during or after the procedures. In contrast to the commonly used dichotomous outcome FA vs no FA, the allergy status is interpreted in multiple categories to reflect the complexity of clinical decision-making. The proposed toolbox sets a standard for improved documentation and harmonized interpretation of DBPCFCs. By a detailed documentation and common terminology for communicating outcomes, these tools hope to reduce the influence of subjective judgment of supervising physicians. All forms are publicly available for further evolution and free use in clinical and research settings. © 2016 The Authors. Allergy Published by John Wiley & Sons Ltd.

Medical ethics, moral philosophy and moral tradition.

PubMed

Murray, T H

1987-01-01

Medical ethics is commonly assumed to be a form of 'applied moral philosophy' in which practical moral judgments are deduced from moral theories. This account of the relationship between moral theory and moral judgment is inadequate in several reports. The deductivist approach often results in inadequate attention being given to social, historical and developmental contexts. It also fails to explain some common phenomena in practical moral reasoning. In contrast to the emphasis in deductivism, a case-centered or casuistic practical ethics insists on immersion in the particularities of cases and on interpretation of details in light of moral maxims and other mid-level forms of moral reasoning. Two features of casuistics that ought to be distinguished but frequently are not, are: (1) the emphasis on immersion and interpretation, and (2) a claim about the relation between moral judgment and moral theory as sources of moral knowledge. Once we consider case-centered moral judgments as sources of moral knowledge, we must also begin to look critically but open-mindedly to moral traditions which, upon examination, appear to be more dynamic and to have more reformist potential than is commonly assumed.

Reaction schemes visualized in network form: the syntheses of strychnine as an example.

PubMed

Proudfoot, John R

2013-05-24

Representation of synthesis sequences in a network form provides an effective method for the comparison of multiple reaction schemes and an opportunity to emphasize features such as reaction scale that are often relegated to experimental sections. An example of data formatting that allows construction of network maps in Cytoscape is presented, along with maps that illustrate the comparison of multiple reaction sequences, comparison of scaffold changes within sequences, and consolidation to highlight common key intermediates used across sequences. The 17 different synthetic routes reported for strychnine are used as an example basis set. The reaction maps presented required a significant data extraction and curation, and a standardized tabular format for reporting reaction information, if applied in a consistent way, could allow the automated combination of reaction information across different sources.

Hypohidrotic ectodermal dysplasia (HED) is a rare disease characterized by deficiency in development of structure derived from the ectoderm and is caused by mutations in the genes EDA, EDAR, or EDARADD. Phenotypes caused by mutations in these three may exhibit similar clinical features, explained by a common signaling pathway. Mutations in EDA gene cause X linked HED, which is the most common form. Mutations in EDAR and EDARADD genes cause autosomal dominant and recessive form of HED. The most striking clinical findings in HED are hypodontia, hypotrichosis and hypohidrosis that can lead to episodes of hyperthermia. We report on clinical findings in a child with HED with autosomal dominant inheritance pattern with a heterozygous mutation c.1072C>T (p.Arg358X) in the EDAR gene. A review of the literature with regard to other cases presenting the same mutation has been carried out and discussed. Sociedad Argentina de Pediatría.

Combining 3D printed forms with textile structures - mechanical and geometrical properties of multi-material systems

Sabantina, L.; Kinzel, F.; Ehrmann, A.; Finsterbusch, K.

2015-07-01

The 3D printing belongs to the rapidly emerging technologies which have the chance to revolutionize the way products are created. In the textile industry, several designers have already presented creations of shoes, dresses or other garments which could not be produced with common techniques. 3D printing, however, is still far away from being a usual process in textile and clothing production. The main challenge results from the insufficient mechanical properties, especially the low tensile strength, of pure 3D printed products, prohibiting them from replacing common technologies such as weaving or knitting. Thus, one way to the application of 3D printed forms in garments is combining them with textile fabrics, the latter ensuring the necessary tensile strength. This article reports about different approaches to combine 3D printed polymers with different textile materials and fabrics, showing chances and limits of this technique.

Similarities in biochemical findings have suggested that Salla disease (SD) and the infantile form of sialic acid storage disease (ISSD) could represent allelic disorders, despite their drastically different clinical phenotypes. SD and ISSD are both characterized by lysosomal storage of free N-acetyl neuraminic acid. However, in SD the increase detected in urine is 8 to 24-fold, whereas in ISSD the corresponding amount is 20 to 50-fold and patients are also more severely affected. Here we report linkage studies in 50 Finnish SD families and 26 non-Finnish families with no genealogical connections to Finns affected either with the Finnish type ofmore » SD, the {open_quotes}intermediate{close_quotes} form of the disease, or ISSD. All forms of the disease show linkage to the same locus on 6q14-q15. Haplotype analyses of Finnish SD chromosomes revealed one common haplotype, which was also seen in most of the non-Finnish patients with Finnish type of SD. This ancestral haplotype deviated from those observed in ISSD patients, who had a different common haplotype. 35 refs., 2 figs., 5 tabs.« less

Familial neonatal isolated cardiomyopathy caused by a mutation in the flavoprotein subunit of succinate dehydrogenase

Cardiomyopathies are common disorders resulting in heart failure; the most frequent form is dilated cardiomyopathy (DCM), which is characterized by dilatation of the left or both ventricles and impaired systolic function. DCM causes considerable morbidity and mortality, and is one of the major causes of sudden cardiac death. Although about one-third of patients are reported to have a genetic form of DCM, reported mutations explain only a minority of familial DCM. Moreover, the recessive neonatal isolated form of DCM has rarely been associated with a mutation. In this study, we present the association of a mutation in the SDHA gene with recessive neonatal isolated DCM in 15 patients of two large consanguineous Bedouin families. The cardiomyopathy is presumably caused by the significant tissue-specific reduction in SDH enzymatic activity in the heart muscle, whereas substantial activity is retained in the skeletal muscle and lymphoblastoid cells. Notably, the same mutation was previously reported to cause a multisystemic failure leading to neonatal death and Leigh's syndrome. This study contributes to the molecular characterization of a severe form of neonatal cardiomyopathy and highlights extreme phenotypic variability resulting from a specific missense mutation in a nuclear gene encoding a protein of the mitochondrial respiratory chain.

2012-01-01

Background To reduce study start-up time, increase data sharing, and assist investigators conducting clinical studies, the National Institute of Neurological Disorders and Stroke embarked on an initiative to create common data elements for neuroscience clinical research. The Common Data Element Team developed general common data elements which are commonly collected in clinical studies regardless of therapeutic area, such as demographics. In the present project, we applied such approaches to data collection in Friedreich ataxia, a neurological disorder that involves multiple organ systems. Methods To develop Friedreich’s ataxia common data elements, Friedreich’s ataxia experts formed a working group and subgroups to define elements in: Ataxia and Performance Measures; Biomarkers; Cardiac and Other Clinical Outcomes; and Demographics, Laboratory Tests and Medical History. The basic development process included: Identification of international experts in Friedreich’s ataxia clinical research; Meeting via teleconference to develop a draft of standardized common data elements recommendations; Vetting of recommendations across the subgroups; Dissemination of recommendations to the research community for public comment. Results The full recommendations were published online in September 2011 at http://www.commondataelements.ninds.nih.gov/FA.aspx. The Subgroups’ recommendations are classified as core, supplemental or exploratory. Template case report forms were created for many of the core tests. Conclusions The present set of data elements should ideally lead to decreased initiation time for clinical research studies and greater ability to compare and analyze data across studies. Their incorporation into new and ongoing studies will be assessed in an ongoing fashion to define their utility in Friedreich’s ataxia. PMID:23239403

Toxoplasmosis is a parasitic infection divided into congenital and acquired forms. In the latter form, malaise, fatigue, and lymphadenopathy are commonly found, and submandibular lymphadenopathy is sometimes a manifestation. In children, cervical lymph nodes usually are affected. This is a case of a 13-year-old boy suffering from acquired toxoplasmosis, in which submandibular lymphadenopathy was the only clinical sign of the disease. Meticulous history taking, clinical examination, and specific serological tests should be performed in these cases. Positive serological results will confirm toxoplasmosis infections. Conservative treatment must be attempted initially.

The primary purpose of this study was to examine concussion management practice patterns among sports medicine physicians in the United States. Cross-sectional study using a web-based survey. Members of the American Medical Society for Sports Medicine (AMSSM). We distributed a questionnaire to physician members of the AMSSM assessing the current practices for evaluating and managing concussions sustained during sports. Specifically, we asked respondents about their use of management guidelines, medications, balance assessments, neuropsychological tests, and return-to-play strategies. Of the 3591 members emailed, 425 (11.8%) respondents responded. Ninety-seven percent of respondents reported basing current management of sport-related concussion on a published set of criteria, with a majority (91.9%) following the guidelines provided by the Fourth International Conference on Concussion in Sport. Seventy-six percent of respondents reported using medication beyond 48 hours postinjury. Acetaminophen was reported as the most commonly administered medication, although tricyclic antidepressants and amantadine were also commonly administered. Vitamins, minerals, and dietary supplements were also reported as commonly administered. Most respondents reported using a form of neuropsychological testing (87.1%). A majority of respondents (88.6%) reported allowing athletes to return to competition after concussion only once the athlete becomes symptom free and completes a return-to-play protocol. Most sports medicine physicians seem to use recently developed guidelines for concussion management, regularly use medications and neuropsychological testing in management strategies, and follow established return-to-play guidelines. Sports medicine physicians seem to have clinical expertise in the management of sport-related concussion.

Mattick and Clarke's (1998) Social Interaction Anxiety Scale (SIAS) and Social Phobia Scale (SPS) are commonly used self-report measures that assess 2 dimensions of social anxiety. Given the need for short, readable measures, this research proposes short forms of both scales. Item-level analyses of readability characteristics of the SIAS and SPS items led to the selection of 6 items from each scale for use in the short forms. The SIAS and SPS short forms had reading levels at approximately the 6th and 5th grade level, respectively. Results using nonclinical (Study 1: N = 469) and clinical (Study 2: N = 145) samples identified these short forms as being factorially sound, possessing adequate internal consistency, and having strong convergence with their full-length counterparts. Moreover, these short forms showed convergence with other measures of social anxiety, showed divergence from measures assessing related constructs, and predicted concurrent interpersonal functioning. Recommendations for the use of these short forms are discussed.

How Prediction Errors Shape Perception, Attention, and Motivation

den Ouden, Hanneke E. M.; Kok, Peter; de Lange, Floris P.

2012-01-01

Prediction errors (PE) are a central notion in theoretical models of reinforcement learning, perceptual inference, decision-making and cognition, and prediction error signals have been reported across a wide range of brain regions and experimental paradigms. Here, we will make an attempt to see the forest for the trees and consider the commonalities and differences of reported PE signals in light of recent suggestions that the computation of PE forms a fundamental mode of brain function. We discuss where different types of PE are encoded, how they are generated, and the different functional roles they fulfill. We suggest that while encoding of PE is a common computation across brain regions, the content and function of these error signals can be very different and are determined by the afferent and efferent connections within the neural circuitry in which they arise.

Intimate partner violence (IPV) is exceedingly common in conflict and post-conflict settings. We first seek to describe factors associated with past 12 month IPV amongst currently married women in Afghanistan, focused on the factors typically assumed to drive IPV. Second, to describe whether IPV is independently associated with a range of health outcomes. Cross-sectional analysis of currently married Afghan women, comprising the baseline study of a trial to prevent IPV. We use multinomial regression, reporting adjusted relative-risk ratios to model factors associated with the different forms of IPV, comparing no IPV, emotional IPV only, and physical IPV and emotional IPV. Second we assessed whether experience of emotional IPV, and physical IPV, were independently associated with health outcomes, reporting adjusted ß coefficients and adjusted odds ratios as appropriate. Nine hundred thirty five currently married women were recruited, 11.8% experienced only emotional IPV and 23.1% experienced physical and emotional IPV. Emotional IPV only was associated with attending a women's group, greater food insecurity, her husband having more than one wife, experiencing other forms of family violence, and more inequitable community gender norms. Experiencing both physical IPV and emotional IPV was associated with attending a women's group, more childhood trauma, husband cruelty, her husband having more than one wife, experiencing other forms of family violence, more inequitable community gender norms, and greater reported disability. Emotional IPV and physical IPV were independently associated with worse health outcomes. IPV remains common in Afghanistan. Economic interventions for women alone are unlikely to prevent IPV and potentially may increase IPV. Economic interventions need to also work with husbands and families, and work to transform community level gender norms. NCT03236948 . Registered 28 July 2017, retrospectively registered.

We report the first observational evidence for pairs of main-belt asteroids with bodies in each pair having nearly identical orbits. The existence of ~60 pairs identified here cannot be reconciled with random fluctuations of the asteroid orbit density and rather suggests a common origin of the paired objects. We propose that the identified pairs formed by (i) collisional disruptions of km-sized and larger parent asteroids, (ii) Yarkovsky-O'Keefe-Radzievski-Paddack (YORP)-induced spin-up and rotational fission of fast-rotating objects, and/or (iii) splitting of unstable asteroid binaries. In case (i), the pairs would be parts of compact collisional families with many km- and sub-km-size members that should be found by future asteroid surveys. Our dynamical analysis suggests that most identified pairs formed within the past lsim1 Myr, in several cases even much more recently. For example, paired asteroids (6070) Rheinland and (54827) 2001 NQ8 probably separated from their common ancestor only 16.5-19 kyr ago. Given their putatively very recent formation, the identified objects are prime candidates for astronomical observations. The title paraphrases that of Hirayama's 1918 paper "Groups of asteroids probably of a common origin," where the first evidence was given for groups of asteroid fragments produced by disruptive collisions.

Alpha1-antitrypsin (AAT) deficiency is a hereditary disorder associated with reduced AAT plasma levels, predisposing adults to pulmonary emphysema. The most common genetic AAT variants found in patients are the mildly deficient S and the severely deficient Z alleles, but several other pathogenic rare alleles have been reported. While the plasma AAT deficiency is a common trait of the disease, only a few AAT variants, including the prototypic Z AAT and some rare variants, form cytotoxic polymers in the endoplasmic reticulum of hepatocytes and predispose to liver disease. Here we report the identification of three new rare AAT variants associated to reduced plasma levels and characterize their molecular behaviour in cellular models. The variants, called Mpisa (Lys259Ile), Etaurisano (Lys368Glu) and Yorzinuovi (Pro391His), showed reduced secretion compared to control M AAT, and accumulated to different extents in the cells as ordered polymeric structures resembling those formed by the Z variant. Structural analysis of the mutations showed that they may facilitate polymerization both by loosening ‘latch’ interactions constraining the AAT reactive loop and through effects on core packing. In conclusion, the new AAT deficiency variants, besides increasing the risk of lung disease, may predispose to liver disease, particularly if associated with the common Z variant. The new mutations cluster structurally, thus defining a region of the AAT molecule critical for regulating its conformational state. PMID:22723858

In 2009, researchers from Johns Hopkins University's Armstrong Institute for Patient Safety and Quality; public agencies, including the FDA; and private partners, including the Emergency Care Research Institute and the University HealthSystem Consortium (UHC) Safety Intelligence Patient Safety Organization, sought to form a public-private partnership for the promotion of patient safety (P5S) to advance patient safety through voluntary partnerships. The study objective was to test the concept of the P5S to advance our understanding of safety issues related to ventilator events, to develop a common classification system for categorizing adverse events related to mechanical ventilators, and to perform a comparison of adverse events across different adverse event reporting systems. We performed a cross-sectional analysis of ventilator-related adverse events reported in 2012 from the following incident reporting systems: the Pennsylvania Patient Safety Authority's Patient Safety Reporting System, UHC's Safety Intelligence Patient Safety Organization database, and the FDA's Manufacturer and User Facility Device Experience database. Once each organization had its dataset of ventilator-related adverse events, reviewers read the narrative descriptions of each event and classified it according to the developed common taxonomy. A Pennsylvania Patient Safety Authority, FDA, and UHC search provided 252, 274, and 700 relevant reports, respectively. The 3 event types most commonly reported to the UHC and the Pennsylvania Patient Safety Authority's Patient Safety Reporting System databases were airway/breathing circuit issue, human factor issues, and ventilator malfunction events. The top 3 event types reported to the FDA were ventilator malfunction, power source issue, and alarm failure. Overall, we found that (1) through the development of a common taxonomy, adverse events from 3 reporting systems can be evaluated, (2) the types of events reported in each database were related to the purpose of the database and the source of the reports, resulting in significant differences in reported event categories across the 3 systems, and (3) a public-private collaboration for investigating ventilator-related adverse events under the P5S model is feasible.

ABSTRACT Duchenne muscular dystrophy (DMD) is an recessive X-linked mediated, musculoskeletal disorder that affects only males. It is the most common and severe form of muscular dystrophy where there is failure to manufacture dystrophin. Clinically, it is characterized by progressive muscle wasting eventually leading to premature death. This case report describes the genetic, oral and systemic findings in two cases of DMD in male siblings. How to cite this article: Suneja B, Suneja ES, Adlakha VK, Chandna P.

To examine the frequency of physical and emotional health problems associated with labor and their relationship with self-rated health measures. Four hundred women were enrolled. Data collection was accomplished through the completion of a form on sociodemographic and obstetric characteristics, a questionnaire that measured the self-rated health level as well as physical health problems, and Edinburgh Postpartum Depression Scale. Most commonly reported health problems in the initial six-week period were fatigue (77.5%), sleep disturbance (76.0%), and dysuria (61.3%). At one-year postpartum, fatigue (33.9%), sleep disturbance (32.8%) and constipation (15.5%) were the most commonly reported complaints. Those who self-reported a "poor health" at six weeks and one year comprised of 40.0% and 19.8% of the participants, respectively. Further studies in other populations are warranted to better delineate the prevalence rates, which will provide useful data for developing policies aimed at improving postpartum care.

Acne vulgaris is the most common dermatological condition encountered in adolescents. It was to determine the prevalence of acne vulgaris and its impact of the quality of life among adolescents attending secondary schools in Sohag Province, Upper Egypt. This was a cross-sectional study conducted in randomly selected governmental and technical secondary schools in Sohag Province, Upper Egypt. Approval was taken from the scientific research committee of Sohag Faculty of Medicine and also from Ministry of Education. Every student with acne was subjected to full medical history and local examination of head and neck to assess the severity of acne vulgaris. Assessment of the impact of acne vulgaris on their quality of life was carried out using self-reported validated specific questionnaire, the Cardiff Acne Disability Index (CADI). This study included 994 teenage secondary school students. The overall prevalence of acne vulgaris was 333 (33.5%). The mean age of the students with acne was 16.84±0.87. Acne vulgaris was more common among females than among males (200, 60% vs 133, 40%). The most common form of acne vulgaris was mild 178, 53%, followed by moderate form 135, 41%, and severe form 20, 6%. CADI score was significantly related to the disease grade and it was maximum among those with severe grade, followed by moderate and lastly mild disease grade. Acne vulgaris is a common skin disease and has a valuable impact on quality of life among adolescents attending secondary schools in Sohag Province, Upper Egypt. © 2017 Wiley Periodicals, Inc.

Assessing the Prevalence of Traumatic Head Injury amongst Recreational Surfers in the United States

2015-01-01

Surfing is a popular recreational sport that carries a substantial risk of injury. Although head injuries are frequently documented in the surfing population, an in depth assessment of the prevalence of surfing-related head injury has not been reported. A web-based survey was conducted in May of 2015. Participants were asked a series of questions regarding surfing-related injuries and demographic characteristics. A total of 50 responses were obtained, of which 35 (70%) reported sustaining a head injury. The most common injury was laceration of the head/face (n=27), followed by concussion (n=13). Other injuries, such as skull fracture and broken nose, were also reported. Only 2 of the 50 participants reported wearing a protective helmet. Neurosurgical intervention was required in 2 instances. Increased emphasis on preventative measures by the medical community may reduce the future incidence of such injuries. Medical professionals should be aware of the most common forms of injury sustained by the surfing population in order to better recognize and treat these conditions. PMID:26668771

Recent child maltreatment research has highlighted the very different context of poverty for Black and White children. Neglect is the most common form of maltreatment and strongly associated with poverty. Neglect is, however, not a unitary construct. We lack an understanding of whether reporting of and responding to different types of neglect may vary by poverty, race, or the intersection of the two. Administrative census, child welfare, welfare, health, and education data were used to examine how family and community poverty factors associate with various subtypes of neglect and subsequent case dispositions for Black and White children. Black children reported to child welfare reside in far poorer communities than Whites, even after taking into account family income (Aid to Families with Dependent Children [AFDC]/Temporary Aid to Needy Families [TANF]). Black children were more commonly reported and substantiated for severe and basic needs neglect. Community poverty indicators had a different relationship to report disposition for Black as compared to White children after controlling for neglect subtypes, child and family characteristics. Implications for practice and policy are discussed. PMID:23109353

The occurrence of fine-grained magnetite in the Fe-rich rims surrounding carbonate globules in the martian meteorite ALH84001, originally described in , have been proposed as fossil remains of primitive martian organisms. Here we report observations on size and shape distributions of magnetites from ALH84001 and compare them to biogenic and inorganic magnetite crystals of terrestrial origin. While some magnetite morphology is not unequivocally diagnostic for its biogenicity, such as cubodial forms of magnetite, which are common in inorganically formed magnetites, other morphologies of magnetite (parallel-epiped or elongated prismatic and arrowhead forms) are more likely signatures of biogenic activity. Some ALH 84001 magnetite particles described below have unique morphology and length-to-width ratios that are indistinguishable from a variety of terrestrial biogenic magnetite and distinct from all known inorganic forms of magnetite.

Extensive animal research has demonstrated the vulnerability of the brain to early life stress (ELS) with consequences for emotional development and mental health. However, the influence of moderate and common forms of stress on early human brain development is less well-understood and precisely characterized. To date, most work has focused on severe forms of stress, and/or on brain functioning years after stress exposure. In this report we focused on conflict between parents (interparental conflict), a common and relatively moderate form of ELS that is highly relevant for children's mental health outcomes. We used resting state functional connectivity MRI to examine the coordinated functioning of the infant brain (N = 23; 6-12-months-of-age) in the context of interparental conflict. We focused on the default mode network (DMN) due to its well-characterized developmental trajectory and implications for mental health. We further examined DMN strength as a mediator between conflict and infants' negative emotionality. Higher interparental conflict since birth was associated with infants showing stronger connectivity between two core DMN regions, the posterior cingulate cortex (PCC) and the anterior medial prefrontal cortex (aMPFC). PCC to amygdala connectivity was also increased. Stronger PCC-aMPFC connectivity mediated between higher conflict and higher negative infant emotionality. The developing DMN may be an important marker for effects of ELS with relevance for emotional development and subsequent mental health. Increasing understanding of the associations between common forms of family stress and emerging functional brain networks has potential to inform intervention efforts to improve mental health outcomes. © 2015 Association for Child and Adolescent Mental Health.

2009-01-01

Purpose: The purpose of this paper is to report 14 new cases of unilateral retinitis pigmentosa and three new cases of cone-rod dystrophy and to compare the similarities and dissimilarities to those found in the bilateral forms of these disorders. Methods: A total of 272 cases of retinitis pigmentosa and 167 cases of cone-rod dystrophy were studied by corneal full field electroretinograms and electrooculograms. The student t-test was used to compare categories. Results: The percentage of familial and nonfamilial cases was the same for the bilateral and unilateral forms of the disease. In our series, unilateral retinitis pigmentosa makes up approximately 5% of the total population of retinitis pigmentosa, while unilateral cone-rod dystrophy makes up only about 2% of the total. In the familial forms of unilateral retinitis pigmentosa the most common inheritance pattern was autosomal dominant and all affected relatives had bilateral disease. Conclusion: Unilateral retinitis pigmentosa and cone-rod dystrophy appear to be directly related to the more common bilateral forms of these disorders. The genetic mechanisms which account for asymmetric disorders are not currently understood. It may be a different unidentified mutation at a single loci or it is possible that nonlinked mutations in multiple loci account for this unusual disorder. PMID:19668577

Data capture is one of the most expensive phases during the conduct of a clinical trial and the increasing use of electronic health records (EHR) offers significant savings to clinical research. To facilitate these secondary uses of routinely collected patient data, it is beneficial to know what data elements are captured in clinical trials. Therefore our aim here is to determine the most commonly used data elements in clinical trials and their availability in hospital EHR systems. Case report forms for 23 clinical trials in differing disease areas were analyzed. Through an iterative and consensus-based process of medical informatics professionals from academia and trial experts from the European pharmaceutical industry, data elements were compiled for all disease areas and with special focus on the reporting of adverse events. Afterwards, data elements were identified and statistics acquired from hospital sites providing data to the EHR4CR project. The analysis identified 133 unique data elements. Fifty elements were congruent with a published data inventory for patient recruitment and 83 new elements were identified for clinical trial execution, including adverse event reporting. Demographic and laboratory elements lead the list of available elements in hospitals EHR systems. For the reporting of serious adverse events only very few elements could be identified in the patient records. Common data elements in clinical trials have been identified and their availability in hospital systems elucidated. Several elements, often those related to reimbursement, are frequently available whereas more specialized elements are ranked at the bottom of the data inventory list. Hospitals that want to obtain the benefits of reusing data for research from their EHR are now able to prioritize their efforts based on this common data element list.

Medicare cost reports (MCR), Internal Revenue Service form 990s (IRS 990), and audited financial statements (AFS) vary in their content, detail, purpose, timeliness, and certification. The purpose of this study was to compare selected financial data elements and characterize the extent of differences in financial data and ratios across the MCR, IRS 990, and AFS for a sample of nonprofit critical access hospitals (CAHs). Line items from AFS of 47 CAHs were compared to data reported in the hospitals' MCR and IRS 990s. Line items were based on 9 financial indicators commonly used to assess hospital financial performance. Of the indicators examined, the equity financing ratio most frequently matched between the 3 reports, while salaries and benefits to total expenses and debt service coverage were often different. Variances were driven by differences in individual account balances used to construct the ratios. Relative to AFS, cash was frequently lower on the IRS 990 while marketable securities and unrestricted investments were often higher. Other revenue and net income were consistently lower on the MCR and IRS 990, and depreciation was often higher on the MCR. The majority of total assets and fund balance (equity) values matched across the 3 reports, suggesting differences in classification among detailed accounts were more common than variances between the component totals (total assets, total liabilities, and fund balance). Health policy researchers should consider the impact of these variances on study results and consider ways to improve the availability and quality of financial accounting information. © 2012 National Rural Health Association.

Eighty-seven years ago, Köhler reported that the majority of students picked the same answer in a quiz: Which novel word form ('maluma' or 'takete') went best with which abstract line drawing (one curved, one angular). Others have consistently shown the effect in a variety of contexts, with only one reported failure by Rogers and Ross. In the spirit of transparency, we report our own failure in the same journal. In our study, speakers of Syuba, from the Himalaya in Nepal, do not show a preference when matching word forms 'kiki' and 'bubu' to spiky versus curvy shapes. We conducted a meta-analysis of previous studies to investigate the relationship between pseudoword legality and task effects. Our combined analyses suggest a common source for both of the failures: 'wordiness' - We believe these tests fail when the test words do not behave according to the sound structure of the target language.

Child maltreatment can have long-term adverse effects. Quantifying the scope and characteristics of child maltreatment is necessary for effective prevention in Puerto Rico. The National Child Abuse and Neglect Data System Child File contains all the reports of child maltreatment from the United States (US) and Puerto Rico. A child maltreatment victim is defined as a child whose maltreatment was substantiated or indicated by the local child protective agency. We compared reporting and victimization rates and reporting sources in Puerto Rico, with those in the US and examined characteristics of child maltreatment in Puerto Rico. During 2006-2010, a total of 31,849-40,712 cases of child maltreatment were reported annually in Puerto Rico. Victimization rates are consistently higher in Puerto Rico than in the US (10.7/1,000-14.8/1,000 in Puerto Rico vs. 10.1/1,000-12.1/1,000 in the US), despite consistently lower reporting rates. In 2010, victimization rates were highest among children aged 1-6 years. In Puerto Rico, neglect is the most common form of maltreatment, followed by emotional abuse; however, the majority of victims suffered multiple types of abuse. Reporting was more commonly anonymous in Puerto Rico (29.8%) than in the US (9.4%) and less commonly provided by professionals in Puerto Rico (37.2%) than in the US (58.7%). We identified a high prevalence of child maltreatment in Puerto Rico. A lower reporting rate, higher victimization rate, and substantial percentage of anonymous reporting indicate potential underreporting of child maltreatment in Puerto Rico. Increasing the awareness and training professionals for improved child maltreatment identification could help alleviate the problem of underreporting.

Providing feedback to mammography radiologists and facilities may improve interpretive performance. We conducted a web-based survey to investigate how and why such feedback is undertaken and used in mammographic screening programmes. The survey was sent to representatives in 30 International Cancer Screening Network member countries where mammographic screening is offered. Seventeen programmes in 14 countries responded to the survey. Audit feedback was aimed at readers in 14 programmes, and facilities in 12 programmes. Monitoring quality assurance was the most common purpose of audit feedback. Screening volume, recall rate, and rate of screen-detected cancers were typically reported performance measures. Audit reports were commonly provided annually, but more frequently when target guidelines were not reached. The purpose, target audience, performance measures included, form and frequency of the audit feedback varied amongst mammographic screening programmes. These variations may provide a basis for those developing and improving such programmes. © The Author(s) 2016.

The use of a p-type inorganic semiconductor to form a nanorod scaffold within a polymer-fullerene bulk heterojunction solar cell is reported. The performance of this cell is compared to those made of the commonly used n-type scaffold of ZnO, which has been reported many times in the literature. The scaffold is designed to improve charge-carrier collection by increased mobility in thicker samples. Observations show that generally the device performance shows a negative correlation to nanorod length. By using CuSCN as a p-type inorganic scaffold, a very similar trend is observed. © 2014 The Authors. Published by Wiley-VCH Verlag GmbH & Co. KGaA.

Lifetime co-occurrence of violence victimisation and symptoms of psychological ill health: a cross-sectional study of Swedish male and female clinical and population samples.

PubMed

Simmons, Johanna; Wijma, Barbro; Swahnberg, Katarina

2015-09-28

Lifetime co-occurrence of violence victimisation is common. A large proportion of victims report being exposed to multiple forms of violence (physical, sexual, emotional violence) and/or violence by multiple kinds of perpetrators (family members, intimate partners, acquaintances/strangers). Yet much research focuses on only one kind of victimisation. The aim of this study was to investigate the association between symptoms of psychological ill health, and A) exposure to multiple forms of violence, and B) violence by multiple perpetrators. Secondary analysis of cross-sectional data previously collected for prevalence studies on interpersonal violence in Sweden was used. Respondents were recruited at hospital clinics (women n = 2439, men n = 1767) and at random from the general population (women n = 1168, men n = 2924). Multinomial regression analysis was used to estimate associations between exposure to violence and symptoms of psychological ill health. Among both men and women and in both clinical and population samples, exposure to multiple forms of violence as well as violence by multiple perpetrators were more strongly associated with symptoms of psychological ill health than reporting one form of violence or violence by one perpetrator. For example, in the female population sample, victims reporting all three forms of violence were four times more likely to report many symptoms of psychological ill health compared to those reporting only one form of violence (adj OR: 3.8, 95 % CI 1.6-8.8). In the male clinical sample, victims reporting two or three kind of perpetrators were three times more likely to report many symptoms of psychological ill health than those reporting violence by one perpetrator (adj OR 3.3 95 % CI 1.9-5.9). The strong association found between lifetime co-occurrence of violence victimisation and symptoms of psychological ill-health is important to consider in both research and clinic work. If only the effect of one form of violence or violence by one kind of perpetrator is considered this may lead to a misinterpretation of the association between violence and psychological ill health. When the effect of unmeasured traumata is ignored, the full burden of violence experienced by victims may be underestimated. Different kinds of victimisation can work interactively, making exposure to multiple forms of violence as well as violence by multiple perpetrators more strongly associated with symptoms of psychological ill health than any one kind of victimisation alone.

The role of the general dental practitioner (GDP) in the management of abuse of vulnerable adults.

2012-10-01

Abuse of vulnerable adults is largely under reported. The most common forms of abuse amongst this group are neglect and financial abuse, although an individual may be at risk of any or all forms of abuse. Certain individuals are at an increased risk of abuse due to their domestic environment and any physical or mental disability they may have. Vulnerable adults constitute a significant proportion of the population. GDPs should be aware of the signs of abuse, to be able to identify those individuals at risk, and how and when to raise concerns of abuse to social services.

Fourier transform magnitudes are commonly used in the generation of templates in pattern recognition applications. We report on recent advances in Fourier phase retrieval which are relevant to pattern recognition. We emphasise in particular that the intrinsic form of a finite, positive image is, in general, uniquely related to the magnitude of its Fourier transform. We state conditions under which the Fourier phase can be reconstructed from samples of the Fourier magnitude, and describe a method of achieving this. Computational examples of restoration of Fourier phase (and hence, by Fourier transformation, the intrinsic form of the image) from samples of the Fourier magnitude are also presented.

A Unique Preparation and Delivery Method for Acitretin for Neonatal Harlequin Ichthyosis

Harlequin ichthyosis is a rare form of congenital ichthyosis with a distinct phenotypic appearance. We describe a case of a newborn baby with harlequin ichthyosis who was treated with an oral formulation of acitretin. The treatment resulted in a satisfactory improvement in the skin condition of the patient. The tolerance to the drug was good with no side effects in the patient. The aim of this case report is to highlight an extemporaneous preparation of acitretin from the commonly available capsule form, which is effective for use in neonates with harlequin ichthyosis. It also highlights the risk of exposure to health care providers to acitretin. PMID:29720920

It is a long-standing and commonly held belief in the United Kingdom and elsewhere that the use of elite forms of language reflects superior intellect and education. Expert opinion from sociolinguistics, however, contends that such a view is the result of middle-class bias and cannot be scientifically justified. In the 1960s and 1970s, such…

Case Report: Laparoscopic Approach for Orchiopexy in a 26-Year-Old Man with Accidentally Discovered Persistent Müllerian Duct Syndrome and Bilateral Undescended Testis.

PubMed

Noureldin, Mohamed Essam; Tawfik, Ahmed Mohamed; Shaker, Hassan S

2018-01-01

Background: Persistent Müllerian duct syndrome (PMDS) is not a common form of disorder of sex development in which Müllerian duct derivatives (fallopian tubes, uterus, and the proximal vagina) are present in an otherwise normally differentiated 46 XY male. In most of cases, the challenge comes in the procedure of orchiopexy. Case Presentation: We report a case of a 26-year-old man with PMDS. It was accidentally discovered when the patient presented to our outpatient clinic concerning about his empty scrotum as a premarital check. Diagnostic laparoscopy discovered Mullerian remnants in the form of uterus, cervix, and fallopian tubes with two attached testes to the fallopian tubes. Staged laparoscopic orchiopexy was done. We discuss the presentation, the management of this case in the literature, and our intervention. Conclusion: PMDS is not a common condition. Several concerns present in the management of these cases. Malignant transformation of the testis is the main risk facing those patients. Few literature studies discussed the risk of changing of these remnants into malignant tissue. Thus discussion with the patient, tissue histopathology, expert opinions, and literature review are the main clues in management of such cases.

Chagas' disease.

Chagas' disease, caused by Trypanosoma cruzi, is an important cause of morbidity in many countries in Latin America. The important modes of transmission are by the bite of the reduviid bug and blood transfusion. The organism exists in three morphological forms: trypomastigotes, amastigotes, and epimastigotes. The mechanism of transformation and differentiation is currently being explored, and signal transduction pathways of the parasites may be involved in this process. Parasite adherence to and invasion of host cells is a complex process involving complement, phospholipase, penetrin, neuraminidase, and hemolysin. Two clinical forms of the disease are recognized, acute and chronic. During the acute stage pathological damage is related to the presence of the parasite, whereas in the chronic stage few parasites are found. In recent years the roles of tumor necrosis factor, gamma interferon, and the interleukins in the pathogenesis of this infection have been reported. The common manifestations of chronic cardiomyopathy are arrhythmias and thromboembolic events. Autoimmune, neurogenic, and microvascular factors may be important in the pathogenesis of the cardiomyopathy. The gastrointestinal tract is another important target, and "mega syndromes" are common manifestations. The diagnosis and treatment of this infection are active areas of investigation. New serological and molecular biological techniques have improved the diagnosis of chronic infection. Exacerbations of T. cruzi infection have been reported for patients receiving immuno-suppressive therapy and for those with AIDS. Images PMID:1423218

Hand eczema is common in the nursing profession, and has been reported widely in various parts of the world. The aim of this study was to determine the prevalence and severity of hand eczema among nurses working in a regional hospital in Hong Kong, as well as its psychosocial impact and any possible associated risk factors. The study took the form of a self-report questionnaire survey; 1240 nurses in a regional hospital were asked to participate in the survey by completing the questionnaire and returning it anonymously within 2 weeks. Seven hundred and twenty-four nurses returned the questionnaire (a response rate of 59%). The prevalence of hand eczema among the respondents was 22.1% (160/724). More than 90% had moderate to severe hand eczema. Itchiness and dryness were the most common symptoms. Occupational work, housework, mood, social activities and sleep were particularly affected. Multinomial logistic regressions showed that a personal or family history of atopy and a hand washing frequency of >20 times per day were independent risk factors for hand eczema. Hand eczema is common and severe among Hong Kong nurses. The results of this study suggest that hand eczema is an important problem for nurses and that preventive measures should be emphasized. © 2011 John Wiley & Sons A/S.

The purpose of this study was to estimate the prevalence of self-reported, ROME II-defined constipation and determine the average defecation frequency and stool types in the Iranian population. A self-reported questionnaire was distributed to 1045 participants, including items intended to identify the presence of ROME II-defined functional constipation and the dominant form of stool based on the Bristol Scale. The weekly mean bowel movement frequency in men and women was 12.5 +/- 7.3 and 13.8 +/- 8.0, respectively (p < 0.05). A total of 87.4% of participants had a stool frequency of between 3 and 21 times per week. The prevalence of functional constipation was 32.9%, whereas only 9.6% of participants reported themselves to be constipated (level of agreement kappa = 0.21, 95% confidence interval: 0.15 to 0.27). Soft or formed stool was reported in 75.7% of individuals. Functional constipation is common in the Iranian population, but its diagnosis could not rely on subjective patient complaints. Despite a higher average of bowel frequency, the previously reported normal range of defecation frequency can be applied for the Iranian population.

A clustered origin for isolated massive stars

Lucas, William E.; Rybak, Matus; Bonnell, Ian A.; Gieles, Mark

2018-03-01

High-mass stars are commonly found in stellar clusters promoting the idea that their formation occurs due to the physical processes linked with a young stellar cluster. It has recently been reported that isolated high-mass stars are present in the Large Magellanic Cloud. Due to their low velocities, it has been argued that these are high-mass stars which formed without a surrounding stellar cluster. In this paper, we present an alternative explanation for the origin of these stars in which they formed in a cluster environment but are subsequently dispersed into the field as their natal cluster is tidally disrupted in a merger with a higher mass cluster. They escape the merged cluster with relatively low velocities typical of the cluster interaction and thus of the larger scale velocity dispersion, similarly to the observed stars. N-body simulations of cluster mergers predict a sizeable population of low-velocity (≤20 km s-1), high-mass stars at distances of >20 pc from the cluster. High-mass clusters in which gas poor mergers are frequent would be expected to commonly have haloes of young stars, including high-mass stars, which were actually formed in a cluster environment.

Dynamic transcriptome profiling of Bean Common Mosaic Virus (BCMV) infection in Common Bean (Phaseolus vulgaris L.).

2016-08-11

Bean common mosaic virus (BCMV) is widespread, with Phaseolus species as the primary host plants. Numerous BCMV strains have been identified on the basis of a panel of bean varieties that distinguish the pathogenicity types with respect to the viral strains. The molecular responses in Phaseolus to BCMV infection have not yet been well characterized. We report the transcriptional responses of a widely susceptible variety of common bean (Phaseolus vulgaris L., cultivar 'Stringless green refugee') to two BCMV strains, in a time-course experiment. We also report the genome sequence of a previously unreported BCMV strain. The interaction with the known strain NL1-Iowa causes moderate symptoms and large transcriptional responses, and the newly identified strain (Strain 2 or S2) causes severe symptoms and moderate transcriptional responses. The transcriptional profiles of host plants infected with the two isolates are distinct, and involve numerous differences in splice forms in particular genes, and pathway specific expression patterns. We identified differential host transcriptome response after infection of two different strains of Bean common mosaic virus (BCMV) in common bean (Phaseolus vulgaris L.). Virus infection initiated a suite of changes in gene expression level and patterns in the host plants. Pathways related to defense, gene regulation, metabolic processes, photosynthesis were specifically altered after virus infection. Results presented in this study can increase the understanding of host-pathogen interactions and provide resources for further investigations of the biological mechanisms in BCMV infection and defense.

2015-02-01

Desbuquois dysplasia (DBQD) is a rare skeletal dysplasia characterized by severe short stature, laxity, dislocation of multiple joints and developmental delay. DBQD is clinically heterogeneous. Distinct radiographic hand abnormalities such as the presence of extra-ossification distal to the second metacarpal or normal hand has led to its classification into types 1 and 2. Furthermore, the third type of DBQD, Kim type has been reported which is characterized by short metacarpals and elongated phalanges. However, DBQD Kim type has been exclusively reported in Japanese and Korean and its clinical characteristics remain to be delineated. Mutations in the calcium-activated nucleotidase 1 (CANT1) gene have been reported in all three types of DBQD. Previously reported patients with DBQD Kim type had a common mutation c.676G>A (p.Val226Met), which had a common founder between Japanese and Korean. Here, we report 3 Indian patients with DBQD, Kim type from 2 families which were unrelated to each other. We identified a novel mutation of CANT1, c.467C>T (p.Ser156Phe), in all the patients in the homozygous form. Our results show that DBQD Kim type is not exclusive to East Asians and also report a novel mutation from the Indian subcontinent. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Landscape inheritance: Report of Working Group Number 2

Twidale, C. R.

1985-01-01

The conventional wisdom is, or until recently has been, that the earth's scenery is essentially youthful, much of it being of pleistocene age. The validity of this assertion was questioned, surfaces and forms of much greater antiquity being cited from several cratonic regions, and also from the older orogens. Exhumed forms, some of them of great age (one inselberg landscape of Archaean age was noted), are more common and extensive than has previously been supposed. Epigene forms of Mesozoic ate are increasingly being demonstrated from the world's cratons and orogens. Etch features also are more widely eveloped than has been realized. It was recommended that studies of denudation chronology be undertaken, possible in relation to contrasted cratonic regions. The nature and age range of surfaces that make up the shields ought to be analysed, the processes responsible for shaping the surfaces, and, in the case of the ancien epigene forms, the reasons for their survival.

Acetic acid-Urea-Triton (AUT) PAGE is commonly used method to separate histone variants and their post-translationally modified forms. Coomassie staining is the preferred method for protein visualization; however, its sensitivity is less than that of silver staining. Though silver staining of histones in AUT-PAGE has been reported, the method is time-consuming, dependent on prior staining by Amido black and has not been reported suitable for mass spectrometry. Here, we propose 'SDS-Silver' method for rapid, sensitive and mass spectrometry-compatible staining of histones resolved on AUT-PAGE.

Percutaneous balloon valvuloplasty is considered the standard of care for treatment of valvular pulmonic stenosis, a common congenital defect in dogs. Supravalvular pulmonic stenosis is a rare form of pulmonic stenosis in dogs and standard treatment has not been established. Although, there have been reports of successful treatment of supravalvular pulmonic stenosis with surgical and stenting techniques, there have been no reports of balloon dilation to treat dogs with this condition. Here, a case of supravalvular pulmonic stenosis diagnosed echocardiographically and angiographically in which a significant reduction in pressure gradient was achieved with balloon dilation alone is presented.

A 52-year-old-man was admitted to our hospital for obstructive jaundice. Percutaneous transhepatic cholangio drainage (PTCD) and endscopic retrograde cholangiopancreatography (ERCP) were performed, and pointed out stenosis of lower common bile duct (CBD) and pancreatobiliary maljunction. Brushing cytology of this lesion was negative for malignancy. CT and MRI revealed chronic inflammatory change in groove lesion with no mass formation suggesting tumor. So we diagnosed groove pancreatitis (segmental form) associated with pancreatobiliary maljunction, and operation (resection of the bile duct and biliary reconstruction by Roux-en-Y) was done. Resected specimen was revealed stenosis of the bile duct formed by fibrous tissue with no malignancy compatible to groove pancreatitis pathologically. This is first reported case of groove pancreatits associated with pancreatobiliary maljunction.

A pyogenic granuloma is a tumorlike proliferation that occurs slightly more often in females, frequently involving the gingiva in the maxillary region. Clinically, it presents as a sessile or pedunculated exophytic mass with a smooth or lobulated surface, which tends to bleed easily. Its color can range from pink to dark red. The most common treatment is surgical excision. This case report presents a pyogenic granuloma that formed around an implant 7 years after its insertion. Pyogenic granulomas associated with dental implants are extremely rare; this is the fourth reported case and the first case of pyogenic granuloma to be treated with an Er:YAG laser.

Background Optic disc drusen, which are calcified deposits that form anterior to the lamina cribrosa in the optic nerve, may mimic papilledema. Case Report We report herein three cases referred to us with suspicion of disc swelling and papilledema. Following ophthalmologic evaluation with B-scan ultrasound, red-free fundus photography, and computed tomography, the diagnosis of papilledema was excluded in all cases and optic disc drusen was diagnosed. Conclusions Clinical suspicion of optic disc drusen in cases presenting with swelling of the optic nerve head is important in order to avoid unnecessary interventions and anxiety. The reported cases highlight the commonly encountered clinical presentations and the practical aspects of diagnosis and management of optic disc drusen. PMID:22787500

Speech perception and reading: two parallel modes of understanding language and implications for acquiring literacy naturally.

PubMed

Massaro, Dominic W

2012-01-01

I review 2 seminal research reports published in this journal during its second decade more than a century ago. Given psychology's subdisciplines, they would not normally be reviewed together because one involves reading and the other speech perception. The small amount of interaction between these domains might have limited research and theoretical progress. In fact, the 2 early research reports revealed common processes involved in these 2 forms of language processing. Their illustration of the role of Wundt's apperceptive process in reading and speech perception anticipated descriptions of contemporary theories of pattern recognition, such as the fuzzy logical model of perception. Based on the commonalities between reading and listening, one can question why they have been viewed so differently. It is commonly believed that learning to read requires formal instruction and schooling, whereas spoken language is acquired from birth onward through natural interactions with people who talk. Most researchers and educators believe that spoken language is acquired naturally from birth onward and even prenatally. Learning to read, on the other hand, is not possible until the child has acquired spoken language, reaches school age, and receives formal instruction. If an appropriate form of written text is made available early in a child's life, however, the current hypothesis is that reading will also be learned inductively and emerge naturally, with no significant negative consequences. If this proposal is true, it should soon be possible to create an interactive system, Technology Assisted Reading Acquisition, to allow children to acquire literacy naturally.

Nominalization and Alternations in Biomedical Language

PubMed Central

Cohen, K. Bretonnel; Palmer, Martha; Hunter, Lawrence

2008-01-01

Background This paper presents data on alternations in the argument structure of common domain-specific verbs and their associated verbal nominalizations in the PennBioIE corpus. Alternation is the term in theoretical linguistics for variations in the surface syntactic form of verbs, e.g. the different forms of stimulate in FSH stimulates follicular development and follicular development is stimulated by FSH. The data is used to assess the implications of alternations for biomedical text mining systems and to test the fit of the sublanguage model to biomedical texts. Methodology/Principal Findings We examined 1,872 tokens of the ten most common domain-specific verbs or their zero-related nouns in the PennBioIE corpus and labelled them for the presence or absence of three alternations. We then annotated the arguments of 746 tokens of the nominalizations related to these verbs and counted alternations related to the presence or absence of arguments and to the syntactic position of non-absent arguments. We found that alternations are quite common both for verbs and for nominalizations. We also found a previously undescribed alternation involving an adjectival present participle. Conclusions/Significance We found that even in this semantically restricted domain, alternations are quite common, and alternations involving nominalizations are exceptionally diverse. Nonetheless, the sublanguage model applies to biomedical language. We also report on a previously undescribed alternation involving an adjectival present participle. PMID:18779866

Research funders' roles and perceived responsibilities in relation to the implementation of clinical research results: a multiple case study of Swedish research funders.

Implementation of clinical research results is challenging, yet the responsibility for implementation is seldom addressed. The process from research to the use of clinical research results in health care can be facilitated by research funders. In this paper, we report the roles of ten Swedish research funders in relation to implementation and their views on responsibilities in implementation. Ten cases were studied and compared using semi-structured interviews. In addition, websites and key documents were reviewed. Eight facilitative roles for research funders in relation to the implementation of clinical research results were identified. Three of them were common for several funders: "Advocacy work," "Monitoring implementation outcomes," and "Dissemination of knowledge." Moreover, the research funders identified six different actors responsible for implementation, five of which belonged to the healthcare setting. Collective and organizational responsibilities were the most common forms of responsibilities among the identified actors responsible for implementation. The roles commonly identified by the Swedish funders, "Advocacy work," "Monitoring implementation outcomes," and "Dissemination of knowledge," seem feasible facilitative roles in relation to the implementation of clinical research results. However, many actors identified as responsible for implementation together with the fact that collective and organizational responsibilities were the most common forms of responsibilities entail a risk of implementation becoming no one's responsibility.

Multisensor data fusion for integrated maritime surveillance

1995-01-01

A prototype Integrated Coastal Surveillance system has been developed on Canada's East Coast to provide effective surveillance out to and beyond the 200 nautical mile Exclusive Economic Zone. The system has been designed to protect Canada's natural resources, and to monitor and control the coastline for smuggling, drug trafficking, and similar illegal activity. This paper describes the Multiple Sensor - Multiple Target data fusion system that has been developed. The fusion processor has been developed around the celebrated Multiple Hypothesis Tracking algorithm which accommodates multiple targets, new targets, false alarms, and missed detections. This processor performs four major functions: plot-to-track association to form individual radar tracks; fusion of radar tracks with secondary sensor reports; track identification and tagging using secondary reports; and track level fusion to form common tracks. Radar data from coherent and non-coherent radars has been used to evaluate the performance of the processor. This paper presents preliminary results.

Randomized controlled trials in dentistry: common pitfalls and how to avoid them.

PubMed

Fleming, Padhraig S; Lynch, Christopher D; Pandis, Nikolaos

2014-08-01

Clinical trials are used to appraise the effectiveness of clinical interventions throughout medicine and dentistry. Randomized controlled trials (RCTs) are established as the optimal primary design and are published with increasing frequency within the biomedical sciences, including dentistry. This review outlines common pitfalls associated with the conduct of randomized controlled trials in dentistry. Common failings in RCT design leading to various types of bias including selection, performance, detection and attrition bias are discussed in this review. Moreover, methods of minimizing and eliminating bias are presented to ensure that maximal benefit is derived from RCTs within dentistry. Well-designed RCTs have both upstream and downstream uses acting as a template for development and populating systematic reviews to permit more precise estimates of treatment efficacy and effectiveness. However, there is increasing awareness of waste in clinical research, whereby resource-intensive studies fail to provide a commensurate level of scientific evidence. Waste may stem either from inappropriate design or from inadequate reporting of RCTs; the importance of robust conduct of RCTs within dentistry is clear. Optimal reporting of randomized controlled trials within dentistry is necessary to ensure that trials are reliable and valid. Common shortcomings leading to important forms or bias are discussed and approaches to minimizing these issues are outlined. Copyright © 2014 Elsevier Ltd. All rights reserved.

A latent class approach to understanding patterns of peer victimization in four low-resource settings.

2016-08-17

Peer victimization is a common form of aggression among school-aged youth, but research is sparse regarding victimization dynamics in low- and middle-income countries (LMIC). Person-centered approaches have demonstrated utility in understanding patterns of victimization in the USA. We aimed to empirically identify classes of youth with unique victimization patterns in four LMIC settings using latent class analysis (LCA). We used data on past-year exposure to nine forms of victimization reported by 3536 youth (aged 15 years) from the Young Lives (YL) study in Ethiopia, India (Andhra Pradesh and Telangana states), Peru, and Vietnam. Sex and rural/urban context were examined as predictors of class membership. LCA supported a 2-class model in Peru, a 3-class model in Ethiopia and Vietnam, and a 4-class model in India. Classes were predominantly ordered by severity, suggesting that youth who experienced one form of victimization were likely to experience other forms as well. In India, two unordered classes were also observed, characterized by direct and indirect victimization. Boys were more likely than girls to be in the highly victimized (HV) class in Ethiopia and India. Urban contexts, compared with rural, conferred higher risk of victimization in Ethiopia and Peru, and lower risk in India and Vietnam. The identified patterns of multiple forms of victimization highlight a limitation of common researcher-driven classifications and suggest avenues for future person-centered research to improve intervention development in LMIC settings.

Prospective study of periostitis and finger clubbing in primary biliary cirrhosis and other forms of chronic liver disease.

The association of finger clubbing and periostitis has been reported in primary biliary cirrhosis and, more rarely, in other forms of chronic liver disease. The prevalence of periostitis and its relationship to finger clubbing is unknown. In this prospective study, we have determined the prevalence of periostitis and finger clubbing in 74 patients with primary biliary cirrhosis and 54 with other forms of chronic liver disease. Clubbing was present in 24% of patients with primary biliary cirrhosis, 29% with HBsAg negative chronic active hepatitis, and 23% in the group of miscellaneous liver diseases. Symmetrical periostitis affecting the tibiae and fibulae occurred in 35% of patients with primary biliary cirrhosis, 29% with chronic, active hepatitis and 40% of patients in the miscellaneous group. The distal radii and ulnae were affected in only eight patients (6%). In primary biliary cirrhosis, the presence of finger clubbing was strongly associated with periostitis (P less than 0.01), but this association was uncommon in other forms of chronic liver disease. In all forms of chronic liver disease periostitis commonly occurs in the absence of finger clubbing. Marked tenderness over the distal leg bones is a reliable sign of underlying periostitis, but this sign is present in only a third of affected patients. This study indicates that periostitis affecting the lower leg bones is common in patients with chronic liver disease, and its presence should be sought whether or not the patient has finger clubbing.

Suicide attempts and physical fighting among high school students--United States, 2001.

PubMed

2004-06-11

Violence is a major cause of morbidity and mortality, particularly among youths. In the United States, homicide and suicide are the second and third leading causes of death, respectively, for persons aged 13-19 years. Although suicide commonly is associated with anxiety, depression, and social withdrawal, research suggests a link between violent behaviors directed at oneself (i.e., suicidal behaviors) and violent behaviors directed at others among adolescents. Certain students who engage in extreme forms of violence, such as school shootings, exhibit suicidal ideation or behavior before or during the attack. However, suicidal behavior also might be associated with involvement in less extreme forms of violent behaviors, such as physical fighting, which might be a risk factor for more severe forms of violence. To characterize any potential association between suicide attempts and fighting, CDC analyzed self-reported 2001 data from a nationally representative sample of high school students in the United States. The results of that analysis indicated that students who reported attempting suicide during the preceding 12 months were nearly four times more likely also to have reported fighting than those who reported not attempting suicide. Prevention programs that seek to reduce both suicidal and violent behaviors are needed. Because prevalence of this association was determined to be highest in the 9th grade, these efforts might be most effective if implemented before students reach high school.

The pharmacovigilance program in Nepal is less than a decade old, and is hospital centered. This study highlights the findings of a community based pharmacovigilance program involving the community pharmacists. Objectives: To collect the demographic details of the patients experiencing adverse drug reactions (ADR) reported by the community pharmacists; to identify the common drugs causing the ADRs, the common types of ADRs; and to carry out the causality, severity and preventability assessments of the reported ADRs. Methods: The baseline Knowledge-Attitude-Practices (KAP) of 116 community pharmacists from Pokhara valley towards drug safety was evaluated using a validated (Cronbach alpha=0.61) KAP questionnaire having 20 questions [(knowledge 11, attitude 5 and practice 4) maximum possible score 40]. Thirty community pharmacists with high scores were selected for three training sessions, each session lasting for one to two hours, covering the basic knowledge required for the community pharmacists for ADR reporting. Pharmacist from the regional pharmacovigilance center visited the trained community pharmacists every alternate day and collected the filled ADR reporting forms. Results: Altogether 71 ADRs, from 71 patients (37 males) were reported. Antibiotics/ antibacterials caused 42% (n=37) of the total ADRs followed by non steroidal anti-inflammatory drugs [25% (n=22)]. Ibuprofen/paracetamol combination accounted for ten ADRs. The most common type of ADR was itching [17.2 % (n=20), followed by generalized edema [8.6 % (n=10)]. In order to manage the ADRs, the patients needed medical treatment in 69% (n=49) of the cases. Over two third (69%) of the ADRs had a ‘possible’ association with the suspected drugs and a high percentage (70.4%) were of ‘mild (level 2)’ type. Nearly two third [64.7 % (n=46)] of the ADRs were ‘definitely preventable’. Conclusion: The common class of drugs known to cause ADRs was antibacterial/ antibiotics. Ibuprofen/ Paracetamol combination use of the drug was responsible for more number of ADRs and the most common ADRs were related to dermatological system. Strengthening this program might improve safe use of medicines in the community. PMID:25126141

The aim of the study was to examine psychiatric symptoms in high-functioning adolescents with autism spectrum disorders reported by multiple informants. Forty-three 11- to 17-year-old adolescents with Asperger syndrome (AS) or high-functioning autism (HFA) and 217 typically developed adolescents completed the Youth Self-Report (YSR), while their parents completed the Child Behavior Checklist (CBCL). Teachers of adolescents with AS/HFA completed the Teacher Report Form (TRF). The informants reported significantly more psychiatric symptoms, especially withdrawn, anxious/depressed, social and attention problems, in adolescents with AS/HFA than in controls. In contrast to findings in the general population, the psychiatric problems of adolescents with AS/HFA are well acknowledged by multiple informants, including self-reports. However, anxiety and depressive symptoms were more commonly reported by adolescents with AS/HFA and their teachers than their parents, indicating that some emotional distress may be hidden from their parents.

Child abuse is a major public health crisis and is on the rise. Dermatologists are frequently involved in its evaluation in differentiating abusive injuries from accidental injuries and in excluding pathological conditions that may mimic abuse. Battered child syndrome or physical abuse is not only a common form of child abuse but can also result from a rarer form of child abuse known as Munchausen syndrome by proxy. In this form of abuse, mother, who is the usual perpetrator, induces an illness or abuses the child for her own self-serving psychological needs. We report two cases of battered child syndrome. In both the cases, Psychiatric evaluation was performed on both parents. Observation through one-way mirror was done with the mother and the child alone. Routine hematological and biochemical investigations were done. Diagnosis of Munchausen syndrome by proxy was firmly established in one case and was considered as a possibility in the other. A multidisciplinary team effort is essential in evaluating such cases, and dermatologists should be aware and be well informed about this condition that can be potentially lethal but easily overlooked.

The formation and failure of natural dams

USGS Publications Warehouse

Costa, J.E.; Schuster, R.L.

1987-01-01

Of the numerous kinds of dams that form by natural processes, dams formed from landslides, glacial ice, and neoglacial moraines present the greatest threat to people and property. The most common types of mass movements that form landslide dams are rock and debris avalanches, rock and soil slumps and slides, and mud, debris, and earth flows. The most common initiation mechanisms for dam-forming landslides are excessive rainfall and snowmelt and earthquakes. Landslide dams can be classified into six categories based on their relation with the valley floor. Type I dams (11%) of the 81 landslide dams around the world that were classifed do not reach from one valley side to the other. Type II dams (44%) span the entire valley flood, occasionally depositing material high up on opposite valley sides. Type III dams (41%) move considerable distances both upstream and downstream from the landslide failure. Type IV dams (1%) are rare and involve the contemporaneous failure of material from both sides of a valley. Type V dams (1%) are also rare, and are created when a single landslide sends multiple tongues of debris into a valley forming two or more landslide dams in the same surfaces, that extend under the stream or valley and emerge on the opposite valley side. Many landslide dams fail shortly after formation. Overtopping is by far the most common cause of failure. Glacial ice dams can produce at least nine kinds of ice-dammed lakes. The most dangerous are lakes formed in main valleys dammed by tributary glaciers. Failure can occur by erosion of a drainage tunnel under or through the ice dam or by a channel over the ice dam. Cold polar ice dams generally drain supraglacially or marginally by downmelting of an outlet channel. Warmer temperate-ice dams tend to fail by sudden englacial or subglacial breaching and drainage. Late neoglacial moraine-dammed lakes are located in steep mountain areas affected by the advances and retreats of valley glaciers in the last several centuries. The most common reported failure mechanism is overtopping and breaching by a wave or series of waves in the lake, generated by icefalls, rockfalls, or snow or rock avalanches. Melting of ice-cores or frozen ground and piping and seepage are other possible failure mechanisms. (Lantz-PTT)

A foot pedal operated exercising device is reported that contains a dynamometer formed of a pair of cylinders each containing a piston. The pistons are linked to each other. The upper portions of the two cylinders are joined together by a common opening to provide a common fluid reservoir and each piston is provided with a one way check valve to maintain an adequate supply of working fluid. Fluid from the driven cylinder is transmitted to the other cylinder through separate constant force spring biased valves each valve takes the predominant portion of the pressure drop thereby providing a constant force hydraulic dynamometer. A device is provided to determine the amount of movement of piston travel.

Aldosterone-producing adenoma (APA), one of the most common causes of primary hyperaldosteronism, is clinically characterized by hypertension, increased sodium retention, increased potassium excretion and altered glucose metabolism. APA can also manifest in the form of hyperosmolar hyperglycaemic state (HHS), which is a life-threatening acute diabetic complication. Infection and inadequate fluid replacement are the common precipitating and predisposing factors for the occurrence of HHS. Here, we report a case of occult APA with the initial presentation of HHS, in which an unusually rapid correction of diabetes was observed after correct diagnosis and surgical resection of the APA. To our knowledge, this is the first case with such manifestations and outcome.

To assess the frequency and forms of bullying experienced by medical students, and the associated factors. Cross-sectional questionnaire-based survey. The study was conducted at a private Medical College of Lahore, from January to February 2010. All the students of first and fourth year classes were included in the study with voluntary and anonymous participation. Self administered-questionnaires were given to the students which were completed by them in the presence of the surveyor. A modified version of the British Medical Associations (BMA) medical student's welfare and education survey form was used for data collection. The data was recorded and analyzed using the statistical package for social sciences version 16.0. Data was described in the form of frequencies and percentages. Chi-square test and Fisher exact test were used to test statistical significance between categorical variables at p < 0.05. More than half the students 70 (66%) had experienced some form of bullying in the past 6 months at the Medical College. It was found that 70% (49) of the students who were bullied were females. Sixty-seven percent of students reported experiencing a bullying episode at least once in a month, 26% less than once in a month and 7% at least once in a week. The most common forms were verbal abuse (n=44, 63%) and behavioural gestures i.e. making faces (n=36, 51%), followed by having been ignored or excluded (n=20, 29%). The common perpetrators of all types of bullying were fellow students followed by Professors. Feeling lonely or sad (p=0.024), not having a close friend (p=0.049) and knowledge amongst respondents regarding the availability of support services in their college (p=0.019) were significantly associated with being bullied. Most medical students reported of having been bullied in the last 6 months at the College, with verbal abuse being the commonest form of maltreatment and fellow students followed by Professors being the frequent perpetrators. A history of feeling lonely or sad, not having a close friend and knowledge amongst respondents regarding the availability of support services in their college were significantly associated with these experiences.

Intimate partner violence (IPV) is a common form of violence experienced by pregnant women and is believed to have adverse mental health effects postnatally. This study investigated the association of postnatal depression (PND) and suicidal ideation with emotional, physical and sexual IPV experienced by women during pregnancy. Data were collected from 842 women interviewed postnatally in six postnatal clinics in Harare, Zimbabwe. We used the World Health Organization versions of IPV and Centre for Epidemiological Studies - Depression Scale measures to assess IPV and PND respectively. We derived a violence severity variable and combined forms of IPV variables from IPV questions. Logistic regression was used to analyse data whilst controlling for past mental health and IPV experiences. One in five women [21.4% (95% CI 18.6-24.2)] met the diagnostic criteria for PND symptomatology whilst 21.6% (95% CI 18.8-24.4) reported postpartum suicide thoughts and 4% (95% CI 2.7-5.4) reported suicide attempts. Two thirds (65.4%) reported any form of IPV. Although individual forms of severe IPV were associated with PND, stronger associations were found between PND and severe emotional IPV or severe combined forms of IPV. Suicidal ideation was associated with emotional IPV. Other forms of IPV, except when combined with emotional IPV, were not individually associated with suicidal ideation. Emotional IPV during pregnancy negatively affects women's mental health in the postnatal period. Clinicians and researchers should include it in their conceptualisation of violence and health. Further research must look at possible indirect relationships between sexual and physical IPV on mental health. Copyright © 2016 Elsevier Inc. All rights reserved.

The Variability in Surgical Margin Reporting in Limb Salvage Surgery for Sarcoma

2015-01-01

Background Surgical margins are a standard reported measurement in tumor surgery that has implications for functional outcome, local control, and overall survival. There is no single accepted classification, and it is unclear what form or margin reporting predominates in the sarcoma literature. Methods We performed a PubMed literature search to identify articles that reported surgical margins and oncologic outcomes in limb salvage surgery for sarcoma from 1980 to 2013. We recorded the margin classification, specialty of the journal, specialty of the author, and location of the authors' institution. Results We found that 159/448 (35%) of articles included in the study did not report surgical margins. Of the 289 papers that did include data on margins, 160 (55%) of articles used Enneking's classification. There has been an increase over time in the proportion of articles reporting surgical margins by the residual tumor (R) classification and the proportion of articles reporting margins dichotomously as “positive” or “negative.” Conclusions We did not find a common method for reporting margins in the limb salvage sarcoma literature. Of most concern was over 1/3 of clinical reports of oncologic outcomes did not include margin status, which substantially compromises any conclusions that readers may infer about treatment success, local recurrence, or survival. We believe there should be renewed efforts to encourage use of a common surgical margin reporting system that is simple, reproducible, and prognostic. PMID:26361463

To estimate the prevalence of bullying in school children and to examine its association with common symptoms in childhood. Prospective survey using a pre-tested questionnaire for conducting a semi structured health interview. Randomly selected Public and private schools in a rural area. Children aged 8-12 years studying in three schools and their parents. Bullying was reported by 157 (31.4%) of the 500 children interviewed. There was no significant difference in the prevalence of bullying amongst boys and girls in co-education schools. However, it was significantly low in schools enrolling girls alone. Teasing and keeping names were the commonest forms noticed. Causing physical hurt was reported bv 25 (16%) students. Only 24 (24%) parents were aware that their children were being bullied. Feeling sad, preferring to stay alone and frequent tearing of clothes were almost exclusively noted in bullied children and bullied children were more likely to report symptoms such as school phobia, vomiting and sleep disturbances. Bullying is a common phenomenon amongst school going children. Frequent bullying is associated with certain symptoms and school absenteeism. Healthcare professionals. should be aware of this phenmnenon so that they can diagnose the underlying cause when these symptoms are reported and plan for appropriate interventions.

The frequency and emotional response to bullying victimisation are known to be associated with adolescent mental ill health. A potentially important under-investigated factor is the form of bullying. Four common forms of bullying behaviours are name-calling, physical threats or harm, rumour spreading and social exclusion. To more comprehensively understand bullying victimisation in adolescence, we examined the association of all three factors (frequency, emotional response, form) to psychological distress and emotional wellbeing. A stratified, random sample of adolescents (n = 10, 273; mean age = 14.33 years, standard deviation = 1.68 years) completed validated measures of bullying victimisation (Gatehouse Bullying Questionnaire), psychological distress (K10) and emotional wellbeing (Mental Health Inventory) in classroom time. Associations between the form of bullying victimisation and mental health outcomes were examined. Adolescents reported a high prevalence of all four forms of bullying: teased or called names (30.6%), rumour spreading (17.9%), social exclusion (14.3%) and physical threats or harm (10.7%). Victimisation was independently associated with significantly higher levels of psychological distress and reduced levels of emotional wellbeing for all forms of bullying. In particular, social exclusion had a strong association with mental ill health. Adolescents who experienced frequent bullying that was upsetting reported higher psychological distress and reduced emotional wellbeing. Different forms of bullying victimisation were independently associated with psychological distress and reduced emotional wellbeing. In particular, frequent and upsetting social exclusion requires a targeted and measured response by school communities and health practitioners. © The Royal Australian and New Zealand College of Psychiatrists 2015.

To determine the prevalence and characteristic of injuries in Wushu Competition during the IP' Asian MartialArts Games 2009. Sixty international athletes (38 males) participating in Wushu Competition during the 1st Asian Martial Arts Games 2009. Injuries were recorded on injury report forms to document any injuries seen and treatment provided by tournament physician during competitions. The injury forms described the athlete s causes, type, site, and severity of the injuries. There were 60 international athletes the average age were 22.49 +/- 3.75 years. The prevalence ofinjuries was 228.07/ 1000 athlete exposure (AE). The prevalence in males andfemales was 161.76/1000 AE and 326.09/1000 AE, respectively. The most common injured body parts in males were lower extremities 102.94/1000 AE, followed by head and face injuries 58.82/1000 AE. The most common injured body parts in females were lower extremities 282.61/1000 AE. The most common types of injuries in males were contusions 58.82/1000 AE, concussion 29.41/1000 AE and strain-sprain 29.41/1000 AE. In females the most common type of injury were contusion 195.65/1000 AEfollowed by strain-sprain 130.43/1000 AE. The most common mechanism of injury in males werereceiving a punch 58.82/1000 AE, receiving a kick 44.12/1000 AE and delivering a kick 44.12/1000 AE. Meanwhile, in females common mechanisms were receiving a kick 152.17/1000 AE followed by delivering a kick 130.43/1000 AE. High prevalence of injuries in Wushu competition during the 1" Asian MartialArts Games 2009 revealedfemale injuries were higher than male and had a higher prevalence compared with Muay Thai or Taekwondo competitions.

2012-02-10

The use of MDMA (ecstasy) in Australia is a widespread and growing problem, promoting acute toxicity and disease which can lead to premature death in users. We report four cases of fatal serotonin toxicity caused by the combination of MDMA and moclobemide, a reversible MAO-A inhibitor with potent serotonergic activity. Despite the highly reported toxicity of this drug combination, there are very few reports of fatalities attributed to a MDMA and moclobemide interaction. Pathology and toxicology reports, initial police reports and coroners' findings were examined to determine the circumstances of the deaths. Symptoms of some of the four cases as reported by paramedics and medical staff included hyperthermia, hyperkalemia, profuse sweating, twitching and shaking. Two cases involved moclobemide concentrations consistent with common prescribed doses, while the other two cases involved much higher concentrations often associated with toxicity. Three of these cases presented with some form of heart disease. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

2017-10-01

The development of effective sexual aggression prevention programs for men relies on data garnered from studies using self-report measures of sexual aggression perpetration. However, few studies have focused on understanding and improving self-report measures of sexual aggression perpetration. The current study used open-ended interviews to explore the nature and frequency of community men's (N = 34) unintentional misreporting-including both overreporting and underreporting-on two self-report measures of sexual aggression perpetration: the Sexual Experiences Survey-Long Form Perpetration (SES-LFP; Koss et al., 2007) and the Sexual Strategies Scale (SSS; Strang, Peterson, Hill, & Heiman, 2013a). Item misinterpretation led to both overreporting and underreporting of sexual aggression, although underreporting was more common. Men's interpretations of items, decision-making processes, and reasons for producing discrepant reports across measures were analyzed and discussed. Results could help inform efforts to refine self-report measurement of men's sexual aggression.

Endocapsular hematoma has previously been described as a cataract surgery complication more commonly observed in eyes receiving a combined cataract and glaucoma surgery. However, it can also be a rare form of ocular bleed following thrombolysis with streptokinase. A 65-year-old diabetic male presented to us with complain of sudden painless diminution of vision in his left eye, which he developed while he was being thrombolysed with streptokinase administered intravenously for an episode of acute myocardial infarct. On examination, left eye was pseudophakic with collection of blood in the capsular bag (Endocapsular hematoma). Endocapsular hematoma can be a rare form of ocular bleeding complicated by thrombolysis. Reporting this case becomes more relevant in the present era with increasing number of patients suffering from ischemic heart disease and likely to undergo thrombolysis.

Aspergillosis is a common systemic mycosis which affects immunocompromised and immunocompetent hosts. Aspergillus spp. is wide spread in the environment in most countries, which renders an invasive form of disease. The presence conidial heads are pathognomic to aspergillosis in diagnosis. Actinomycosis is a subacute-to-chronic infection that causes sinus fistula, tract or abscess due to the invasion surrounding the soft tissue. Cervicofacial infection accounts for 50%-60% of all actinomycosis cases. The mandible and nasopharynx are the sites of predilection, but maxillary infection is rare. Aspergillosis and Actinomycosis each of them was reported in case, but mixed infection of both organisms is rare, only one case has been reported. This paper discussed about a case report of coexistence of aspergillosis with actinomycosis in 38-year-old male.

Lymphadenitis is the most common form of tuberculosis in the head and neck region, but it can be seen in the other areas of the head and neck. Nasopharyngeal tuberculosis is a rare condition without pulmonary and systemic involvement. The majority of patients present with neck mass. A 17-year-old female patient admitted to our outpatient clinic with the complaints of swelling on both sides of the neck and hearing loss. The endoscopic examination revealed a nasopharyngeal mass, and biopsies were taken from the mass. The result of pathologic examination was reported as caseating granulomatous inflammation compatible with tuberculosis. In this report, a nasopharyngeal tuberculosis case associated with massive cervical lymphadenopathy was reported, and etiopathogenesis and treatment were also discussed.

Nepal lacks sufficient data on injury and violence. Studies have been done in different regions but there is not a nationwide study on this topic. So, we have designed this systematic review to get a cumulative picture of injury and violence status in Nepal. We searched Medline database, Google scholar database and also all the national medical journals for relevant studies on injuries and violence. Our eligibility criteria included studies done in Nepal, evaluating the incidence of different forms of injuries, and their causes and effects. We excluded case reports, editorials and reviews. All together, we had 23 studies. We made cumulative analysis wherever possible. All the studies were descriptive. In overall, the incidence of injuries was twice as common in male as in female with the ratio of 2.1:1. The economically active population between 20-50 years of age was mostly involved in injuries. Road traffic injuries were the most common form of injuries, most of which (42.5%) involved motorcycles. Pedestrians (48.6%) were the most vulnerable group of population. Falls (48.9%) were the most common cause of neuro traumatic accidents. Our systematic review suggests that injuries and violence pose a big problem; road traffic accidents make the most part of it.

Comparing the efficacy of benzodiazepines and serotonergic anti-depressants for adults with generalized anxiety disorder: a meta-analytic review.

PubMed

Generalized anxiety disorder (GAD) is a common form of anxiety disorder. Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), and benzodiazepines (BZs) are the most commonly prescribed medications for GAD, but little is known about the relative efficacy of these pharmacological treatments. Areas covered: This study provides a meta-analytic review of the efficacy of these medications in the treatment of adults with GAD. A comprehensive literature search yielded 54 articles reporting 56 unique studies with 12,655 participants treated with either pill placebo (6,191 participants), SSRIs (16 trials, 2,712 participants), SNRIs (17 trials, 2,603 participants), or BZs (23 trials, 1,149 participants). The overall combined effect size was modest to moderate (Hedges' g = 0.37, p < 0.0001). Effect sizes decreased significantly over time. SSRIs (Hedges' g = 0.33) and SNRIs (Hedges' g = 0.36) demonstrated significantly lower effect sizes than BZs (Hedges' g = 0.50). These findings were not due to differences in treatment length or publication year. Expert opinion: The results of this study suggest that the most common forms of pharmacotherapy for adult GAD are moderately effective, with BZs being the most effective drug.

Method for Selective Cleaning of Mold Release from Composite Honeycomb Surfaces

NASA Technical Reports Server (NTRS)

Pugel, Diane

2011-01-01

Honeycomb structures are commonly employed as load- and force-bearing structures as they are structurally strong and lightweight. Manufacturing processes for heat-molded composite honeycomb structures commence with the placement of pre-impregnated composite layups over metal mandrels. To prevent permanent bonding between the composite layup and the metal mandrels, an agent, known as a mold release agent, is used. Mold release agents allow the molded composite material to be removed from mandrels after a heat-forming process. Without a specific removal process, mold release agents may continue to adhere to the surface of the composite material, thereby affecting the bonding of other materials that may come into contact with the composite surface in later stages of processing A constituent common to commercially available household cleaning agents is employed for the removal of mold release agents common to the manufacturing of heat-formed composite materials. The reliability of the solvent has been proven by the longevity and reliability of commercial household cleaners. At the time of this reporting, no one has attempted using constituent for this purpose. The material to be cleaned is immersed in the solution, vertically removed so that the solution is allowed to drain along cell walls and into a solvent bath, and then placed on a compressed airflow table for drying.

Oral lichen planus: a report and review of an autoimmune-mediated condition in gingiva.

2012-09-01

Oral lichen planus (OLP) is a chronic autoimmune, mucocutaneous disease that affects the oral mucosa as well as the skin, genital mucosa, scalp, and nails. It is one of the most common dermatological diseases presenting in the oral cavity. An immune-mediated pathogenesis is recognized in lichen planus, although the exact etiology is unknown. The disease most commonly affects middle-aged females. It is infrequently found in children, with a prevalence of about 0.03%, and reports of this are scarce in the literature. The erosive and atrophic forms of OLP are less common, yet they are more likely to cause symptoms. OLP is the target of much controversy, especially in relation to its potential for malignancy. Thus, it is important for clinicians to maintain a high index of suspicion for all intraoral lichenoid lesions. Periodic follow-up of all patients with OLP is recommended. In view of the above, the authors highlight a case of gingival erosive lichen planus affecting a 17-year-old adolescent without concomitant cutaneous lesions, with special emphasis on clinical and microscopic characteristics of the condition and management with retinoids and steroid therapy.

Dementia of Lewy body disease is the second most common degenerative cause of dementia after Alzheimer's disease, among all the dementias. The core features are a progressive dementia, fluctuations in cognitive functions, visual hallucinations, and spontaneous parkinsonism. Rapid eye movement sleep behavior disorder, severe neuroleptic sensitivity, and low dopamine transporter uptake in basal ganglia are other suggestive features. Behavioral abnormalities are commonly present in the form of aggressive behavior, irritability, and uninhibited behaviors. These are mostly seen in the advanced stages of dementia. However, inappropriate sexual behavior is uncommonly seen in such cases. Three types of inappropriate sexual behaviors commonly found in cases of dementia are sex talks, sexual acts, and implied sexual acts. Such inappropriate sexual behaviors have not been described adequately in dementia of Lewy body disease. We report inappropriate sexual behaviors in a case of dementia of Lewy body disease, which improved rapidly after treatment with quetiapine.

Polythelia within Becker's naevus.

Urbani, C E; Betti, R

1998-01-01

We report a case of accessory mammary tissue of type 2a (or polythelia) entirely localized within a Becker's naevus of mixed type in a 32-year-old Caucasian woman. Polythelia was congenital in origin while Becker's naevus appeared during puberty. Renal ultrasonographic studies, laboratory examinations and other instrumental investigations were either normal or negative. Although the association of accessory mammary tissue with Becker's naevus has previously been reported--also in the form of mammorenal and acromammorenal syndromes--this is the first case characterized by an anatomic overlap between the two anomalies. It may be the expression of a common disturbance acting early in embryogenesis in the specific developmental fields involved.

We report a 1D study of optical forces on atoms in a two-frequency laser field. The light couples two ground state hyperfine structure levels to a common excited state of 85Rb, thus forming a Λ system. We observe a new type of sub-Doppler coupling with blue-tuned light that uses neither polarization gradients nor magnetic fields, efficient heating with red tuning, and the spatial phase dependence of these. We observed deflection from a rectified dipole force and determined its velocity dependence and capture range. We report velocity selective resonances associated with Raman transitions. A simplified semiclassical calculation agrees qualitatively with our measurements.

The various forms of non-melanocytic nevi (hamartomas) are usually encountered in pediatric patients, and nevus sebaceous of Jadassohn is the most common to have undifferentiated pilosebaceous units. We report a unique congenital follicular nevus that fails to meet the criteria of any previously described follicular neoplasm, despite the plethora of alternatives. Clinically considered a syringocystadenoma papilliferum, the excised lesion contained multiple dermal nodules that exhibited nearly all stages of follicular differentiation. The periodicity of the follicular proliferations was akin to normal terminal hair, and a prominent perifollicular sheath surrounded each. This benign lesion of abortive hair follicles was unassociated with any established genodermatous syndrome or other adnexal neoplasm.

Choroidal metastases, the most common form of intraocular malignancies, are principally caused by primary tumors from breast, lung, and gastrointestinal tract. These lesions are mostly symptomatic and rarely detected incidentally in the extension study of a previously diagnosed tumor. Leiomyosarcoma is a neoplasm of mesenchymal cells with smooth muscle differentiation and represents the most prevalent soft-tissue sarcoma. Leiomyosarcoma is a notably rare tumor in ophthalmic region. We report a case of primary bone leiomyosarcoma metastatic to the choroid that was treated with chemotherapy and surgery. Although three cases of choroidal metastasis from leiomyosarcomas have been already reported, to our knowledge this is the first case of choroidal metastasis from primary bone leiomyosarcoma.

Optic disc drusen, which are calcified deposits that form anterior to the lamina cribrosa in the optic nerve, may mimic papilledema. We report herein three cases referred to us with suspicion of disc swelling and papilledema. Following ophthalmologic evaluation with B-scan ultrasound, red-free fundus photography, and computed tomography, the diagnosis of papilledema was excluded in all cases and optic disc drusen was diagnosed. Clinical suspicion of optic disc drusen in cases presenting with swelling of the optic nerve head is important in order to avoid unnecessary interventions and anxiety. The reported cases highlight the commonly encountered clinical presentations and the practical aspects of diagnosis and management of optic disc drusen.

Renal angiomyolipoma is a benign tumor formed by smooth muscle, adipose tissue and blood vessels. It is commonly found incidentally and its clinical manifestations are pain and abdominal mass or spontaneous tumor rupture with retroperitoneal bleeding. The clinical presentation of a hemorrhagic shock secondary to a retroperitoneal hematoma is uncommon. We report a 40 year-old male who presented to the emergency room with lumbar pain and deterioration of hemodynamic parameters. The CT scan showed a left renal injury associated to an expansive retroperitoneal process. The abdominal exploration, vascular control of the renal pedicle and nephrectomy allowed a successful outcome.

Langerhans' cell histiocytosis is a rare disorder of unknown etiology characterized by a wide clinical spectrum and varied behavior. Diabetes insipidus is a relatively common feature in Langerhans' cell histiocytosis. The presence of both diabetes insipidus and mellitus associated with histiocytosis in an adult is rare. To our knowledge, only three previous cases have been reported. We report the clinical presentation, pathologic findings and clinical progress in an adult female who had disseminated Langerhans' cell histiocytosis (hypothalamic infiltration, multifocal bone involvement) associated with both diabetes insipidus and mellitus. The pathogenesis of diabetes mellitus in such an association will be discussed.

To explore the frequency, the reasons behind, and the consequences of medicine shortages in Finnish community pharmacies. During the 27-day study period in the autumn of 2013, randomly selected pharmacies reported on medicines that were in short supply from orders made to wholesalers. Altogether 129 (66%, n=195) pharmacies participated in the study, and the study material consisted of 3311 report forms. Of the study pharmacies, 79.8% had medicine shortages daily or almost daily. Medicines in short supply were most commonly medicines that affect the nervous system (30.8%) and the cardiovascular system (17.5%). The reason behind the shortage was reported to the pharmacies in 11.2% of the shortage cases. The medicine shortages caused problems for the pharmacies in 33.0% of the cases. In most cases (67.0%) the medicine shortages did not cause problems for the pharmacies, usually because a substitutable product was available (48.5%). Medicine shortages are common in Finnish community pharmacies. Medicines in short supply were commonly used medicines. The reason behind the shortage was rarely told to the pharmacies. Medicine shortages caused problems for the pharmacies in one-third of all the shortage cases. These shortages may be significant for the customers or the pharmacies, as they cause customer dissatisfaction and increase the workload of the pharmacy staff. Copyright © 2014 Elsevier Ireland Ltd.

Modeling Common-Sense Decisions in Artificial Intelligence

NASA Technical Reports Server (NTRS)

Zak, Michail

2010-01-01

A methodology has been conceived for efficient synthesis of dynamical models that simulate common-sense decision- making processes. This methodology is intended to contribute to the design of artificial-intelligence systems that could imitate human common-sense decision making or assist humans in making correct decisions in unanticipated circumstances. This methodology is a product of continuing research on mathematical models of the behaviors of single- and multi-agent systems known in biology, economics, and sociology, ranging from a single-cell organism at one extreme to the whole of human society at the other extreme. Earlier results of this research were reported in several prior NASA Tech Briefs articles, the three most recent and relevant being Characteristics of Dynamics of Intelligent Systems (NPO -21037), NASA Tech Briefs, Vol. 26, No. 12 (December 2002), page 48; Self-Supervised Dynamical Systems (NPO-30634), NASA Tech Briefs, Vol. 27, No. 3 (March 2003), page 72; and Complexity for Survival of Living Systems (NPO- 43302), NASA Tech Briefs, Vol. 33, No. 7 (July 2009), page 62. The methodology involves the concepts reported previously, albeit viewed from a different perspective. One of the main underlying ideas is to extend the application of physical first principles to the behaviors of living systems. Models of motor dynamics are used to simulate the observable behaviors of systems or objects of interest, and models of mental dynamics are used to represent the evolution of the corresponding knowledge bases. For a given system, the knowledge base is modeled in the form of probability distributions and the mental dynamics is represented by models of the evolution of the probability densities or, equivalently, models of flows of information. Autonomy is imparted to the decisionmaking process by feedback from mental to motor dynamics. This feedback replaces unavailable external information by information stored in the internal knowledge base. Representation of the dynamical models in a parameterized form reduces the task of common-sense-based decision making to a solution of the following hetero-associated-memory problem: store a set of m predetermined stochastic processes given by their probability distributions in such a way that when presented with an unexpected change in the form of an input out of the set of M inputs, the coupled motormental dynamics converges to the corresponding one of the m pre-assigned stochastic process, and a sample of this process represents the decision.

Remote infarct of the temporal lobe with coexistent hippocampal sclerosis in mesial temporal lobe epilepsy.

PubMed

Gales, Jordan M; Prayson, Richard A

2016-02-01

In patients undergoing surgery for temporal lobe epilepsy, hippocampal sclerosis remains the most commonly observed pathology. In addition to hippocampal sclerosis, 5% to 30% of these resections on magnetic resonance imaging contain a second independently epileptogenic lesion, commonly referred to as dual pathology. A second etiology of seizure activity, as seen in dual pathology, may serve as an important cause of treatment failure in striving for post-operative seizure control. Dual pathology, consisting of hippocampal sclerosis and a remote infarct of the adjacent cortex, has been rarely reported. Cases of pathologically confirmed hippocampal sclerosis diagnosed between January 2000 and December 2012 (n = 349) were reviewed, and 7 cases of coexistent infarct (2%) formed the study group. Seven individuals (mean age, 29years; range, 5-47 years) with a mean epilepsy duration of 12.5years (3.3-25 years) and a mean pre-surgery frequency of 15 seizures per week (range, 0.5-56 seizures/week) were followed up postoperatively for a mean duration of 64months (range, 3-137 months). Pathologically, the most common form of hippocampal sclerosis observed was International League against Epilepsy type Ib or severe variant (n = 4). Four of the six individuals with post-surgery follow-up were seizure free at last encounter. The reported incidence of dual pathology, including hippocampal sclerosis and remote infarct, is low (2% in the present study) but may indicate a slightly increased risk of developing hippocampal sclerosis in the setting of a remote infarct. Surgical intervention for such cases anecdotally appears effective in achieving seizure control. Copyright © 2015 Elsevier Inc. All rights reserved.

Mental Reactivation and Pleasantness Judgment of Experience Related to Vision, Hearing, Skin Sensations, Taste and Olfaction

PubMed Central

2016-01-01

Language acquisition is based on our knowledge about the world and forms through multiple sensory-motor interactions with the environment. We link the properties of individual experience formed at different stages of ontogeny with the phased development of sensory modalities and with the acquisition of words describing the appropriate forms of sensitivity. To test whether early-formed experience related to skin sensations, olfaction and taste differs from later-formed experience related to vision and hearing, we asked Russian-speaking participants to categorize or to assess the pleasantness of experience mentally reactivated by sense-related adjectives found in common dictionaries. It was found that categorizing adjectives in relation to vision, hearing and skin sensations took longer than categorizing adjectives in relation to olfaction and taste. In addition, experience described by adjectives predominantly related to vision, hearing and skin sensations took more time for the pleasantness judgment and generated less intense emotions than that described by adjectives predominantly related to olfaction and taste. Interestingly the dynamics of skin resistance corresponded to the intensity and pleasantness of reported emotions. We also found that sense-related experience described by early-acquired adjectives took less time for the pleasantness judgment and generated more intense and more positive emotions than that described by later-acquired adjectives. Correlations were found between the time of the pleasantness judgment of experience, intensity and pleasantness of reported emotions, age of acquisition, frequency, imageability and length of sense-related adjectives. All in all these findings support the hypothesis that early-formed experience is less differentiated than later-formed experience. PMID:27400090

2002-01-01

CONTEXT Prescribing errors involving medication dose formulations have been reported to occur frequently in hospitals. No systematic evaluations of the characteristics of errors related to medication dosage formulation have been performed. OBJECTIVE To quantify the characteristics, frequency, and potential adverse patient effects of prescribing errors involving medication dosage forms . DESIGN Evaluation of all detected medication prescribing errors involving or related to medication dosage forms in a 631-bed tertiary care teaching hospital. MAIN OUTCOME MEASURES Type, frequency, and potential for adverse effects of prescribing errors involving or related to medication dosage forms. RESULTS A total of 1,115 clinically significant prescribing errors involving medication dosage forms were detected during the 60-month study period. The annual number of detected errors increased throughout the study period. Detailed analysis of the 402 errors detected during the last 16 months of the study demonstrated the most common errors to be: failure to specify controlled release formulation (total of 280 cases; 69.7%) both when prescribing using the brand name (148 cases; 36.8%) and when prescribing using the generic name (132 cases; 32.8%); and prescribing controlled delivery formulations to be administered per tube (48 cases; 11.9%). The potential for adverse patient outcome was rated as potentially “fatal or severe” in 3 cases (0.7%), and “serious” in 49 cases (12.2%). Errors most commonly involved cardiovascular agents (208 cases; 51.7%). CONCLUSIONS Hospitalized patients are at risk for adverse outcomes due to prescribing errors related to inappropriate use of medication dosage forms. This information should be considered in the development of strategies to prevent adverse patient outcomes resulting from such errors. PMID:12213138

Intranasal ipratropium bromide for the common cold.

The common cold is one of the most common illnesses in humans and constitutes an economic burden both in terms of productivity and expenditure for treatment. There is no proven cure for the common cold and symptomatic relief is the mainstay of treatment. The use of intranasal ipratropium bromide (IB) has been addressed in several studies and might prove an effective treatment for the common cold. To determine the effect of IB versus placebo or no treatment on severity of rhinorrhoea and nasal congestion in children and adults with the common cold. Subjective overall improvement was another primary outcome and side effects were reported as a secondary outcome. We searched the Cochrane Central Register of Controlled Trials (CENTRAL 2011, Issue 1) which contains the Acute Respiratory Infections Group's Specialised Register, MEDLINE (1950 to January week 4, 2011), MEDLINE in-process and other non-indexed citations (February 2011), EMBASE (1974 to February 2011), AMED (1985 to February 2011), Biosis (1974 to February 2011) and LILACS (1985 to February 2011). Randomised controlled trials (RCTs) comparing IB to placebo or no treatment in children and adults with the common cold. Two review authors independently extracted data and assessed trial quality. We used a standardised form to extract relevant data and we contacted trial authors for additional information. Seven trials with a total of 2144 participants were included. Four studies (1959 participants) addressed subjective change in severity of rhinorrhoea. All studies were consistent in reporting statistically significant changes in favour of IB. Nasal congestion was reported in four studies and was found to have no significant change between the two groups. Two studies found a positive response in the IB group for the global assessment of overall improvement. Side effects were more frequent in the IB group, odds ratio (OR) 2.09 (95% confidence interval (CI) 1.40 to 3.11). Commonly encountered side effects included nasal dryness, blood tinged mucus and epistaxis. For people with the common cold, the existing evidence, which has some limitations, suggests that IB is likely to be effective in ameliorating rhinorrhoea. IB had no effect on nasal congestion and its use was associated with more side effects compared to placebo or no treatment although these appeared to be well-tolerated and self-limiting. There is a need for larger, high-quality trials to determine the effectiveness of IB in relieving common cold symptoms.

Tuberculosis of the parotid gland is extremely unusual. Tuberculosis comprises 2.5% to 10% of parotid gland lesions. Two clinical forms of parotid gland tuberculosis infection exist. One is a diffuse parenchymatous disease (either primary or secondary to nodal disease), resembling common infection. The second is a chronic, slow-growing, painless, and firm parotid mass mimicking a neoplasm. Most of these patients were diagnosed after parotid gland surgery and histopathologic evaluation. Warthin tumor is a well-known benign neoplasm of the salivary glands. It is the second most common tumor of the parotid gland. Mycobacterium tuberculosis within Warthin tumor is also unusual. Five cases with parotid gland tuberculosis within Warthin tumor were reported in the literature. In this report, we present a new patient with parotid gland tuberculosis within the Warthin tumor. This type parotid gland pathology is an extremely rare entity, and to the best of our knowledge, this is the second documented case using polymerase chain reaction. We also discussed the possible mechanisms of development of infection within Warthin tumor.

Quantum Field Energy Sensor based on the Casimir Effect

NASA Astrophysics Data System (ADS)

Ludwig, Thorsten

The Casimir effect converts vacuum fluctuations into a measurable force. Some new energy technologies aim to utilize these vacuum fluctuations in commonly used forms of energy like electricity or mechanical motion. In order to study these energy technologies it is helpful to have sensors for the energy density of vacuum fluctuations. In today's scientific instrumentation and scanning microscope technologies there are several common methods to measure sub-nano Newton forces. While the commercial atomic force microscopes (AFM) mostly work with silicon cantilevers, there are a large number of reports on the use of quartz tuning forks to get high-resolution force measurements or to create new force sensors. Both methods have certain advantages and disadvantages over the other. In this report the two methods are described and compared towards their usability for Casimir force measurements. Furthermore a design for a quantum field energy sensor based on the Casimir force measurement will be described. In addition some general considerations on extracting energy from vacuum fluctuations will be given.

Blastocystis hominis revisited.

Stenzel, D J; Boreham, P F

1996-01-01

Blastocystis hominis is a unicellular organism found commonly in the intestinal tract of humans and many other animals. Very little is known of the basic biology of the organism, and controversy surrounds its taxonomy and pathogenicity. There morphological forms (vacuolar, granular, and ameboid) have been recognized, but recent studies have revealed several additional forms (cyst, avacuolar, and multivacuolar). The biochemistry of the organism has not been studied to any extent, and organelles and structures of unknown function and composition are present in the cells. Several life cycles have been proposed but not experimentally validated. The form used for transmission has not been defined. Infections with the organism are worldwide and appear in both immunocompetent and immunodeficient individuals. Symptoms generally attributed to B. hominis infection are nonspecific, and the need for treatment is debated. If treatment appears warranted, metronidazole is suggested as the drug of choice, although failures of this drug in eradicating the organism have been reported. Infection is diagnosed by light microscopic examination of stained smears or wet mounts of fecal material. Most laboratories identify B. hominis by observing the vacuolar form, although morphological studies indicate that other forms, such as the cyst form and multivacuolar form, also should be sought for diagnosis.

The Low-Level routines form an application-independent graphics package enabling the user community to construct and design scientific charts conforming to the publication and/or viewgraph process. The Low-Level routines allow the user to design unique or unusual report-quality charts from a set of graphics utilities. The features of these routines can be used stand-alone or in conjunction with other packages to enhance or augment their capabilities. This library is written in ANSI FORTRAN 77, and currently uses a CORE-based underlying graphics package, and is therefore machine-independent, providing support for centralized and/or distributed computer systems.

Misdiagnosed crusted scabies in an AIDS patient leads to hyperinfestation.

PubMed

Yari, Niloofar; Malone, C Helen; Rivas, Antonio

2017-03-01

Crusted scabies is a severe, highly contagious form of classic scabies caused by the mite Sarcoptes scabiei var hominis . Crusted scabies is more common in immunosuppressed populations and overcrowded environments. In this condition, the host's immune system is overwhelmed and unable to defend against the mites on the skin, resulting in hyperinfestation of the host. Diagnosis can be challenging because the condition resembles other common skin conditions, such as plaque psoriasis. Furthermore, delayed diagnosis and inappropriate treatment can lead to worsening of the condition. We report a case of crusted scabies that was initially misdiagnosed in a 34-year-old incarcerated man with multidrug-resistant human immunodeficiency virus/AIDS. The patient had a complicated but complete recovery after treatment with permethrin and ivermectin was instituted.

Laser-induced acoustic desorption (LIAD) allows for desorption of neutral nonvolatile compounds independent of their volatility or thermal stability. Many different ionization methods have been coupled with LIAD. Hence, this setup provides a better control over the types of ions formed than other mass spectrometry evaporation/ionization methods commonly used to characterize biomolecules, such as ESI or MALDI. In this study, the utility of LIAD coupled with electron ionization (EI) was tested for the analysis of common amino acids with no derivatization. The results compared favorably with previously reported EI mass spectra obtained using thermal desorption/EI. Further, LIAD/EI mass spectra collected for hydrochloride salts of two amino acids were found to be similar to those measured for the neutral amino acids with the exception of the appearance of an HCl+● ion. However, the hydrochloride salt of arginine showed a distinctly different LIAD/EI mass spectrum than the previously published literature EI mass spectrum, likely due to its highly basic side chain that makes a specific zwitterionic form particularly favorable. Finally, EI mass spectra were measured for seven small peptides, including di-, tri-, and tetrapeptides. These mass spectra show a variety of ion types. However, an type ions are prevalent. Also, electron-induced dissociation (EID) of protonated peptides has been reported to form primarily an type ions. In addition, the loss of small neutral molecules and side-chain cleavages were observed that are reminiscent of other high-energy fragmentation methods, such as EID. Finally, the isomeric dipeptides LG and IG were found to produce drastically different EI mass spectra, thus allowing differentiation of the leucine and isoleucine amino acids in these dipeptides.

Methods: Statistics for total morbidity, primary disability and mortality from cancer in the adult population of the city of Uralsk for 2011-2015 were calculated per 100 thousand. Estimation of morbidity was based on data from form - №12 «Report on the number of diseases registered in patients living in the area of health care organizations and patient population under medical observation”. Evaluation of primary disability was based on form №7 «The distribution of newly recognized disabled by disease class, age, sex and disability groups” for 2011-2015 in Ural city and analysis of cancer was carried out using annual form 7 “Report on the sick, and diseases of malignant neoplasms”. Result: The most common localizations of cancer were the trachea, bronchi, lungs, stomach and mammary glands. High death rates were noted for patients with cancer of the trachea, bronchi, lung, as compared to stomach and esophagus. Conclusion: The results of our investigation and data in the literature indicate that regional characteristics influence the impact of risk factors associated with cancer. An unfavorable environmental background contributes to ill health of urban populations, contributing to development of cancer. Moreover behavioral risk factors are very important, such as smoking, alcohol drinking, and an unhealthy diet. All these factors require urgent adoption of a package of measures for prevention, early detection and timely treatment. Detailed study of cancer is necessary to develop national programs and activities for prevention and control. Creative Commons Attribution License

The cross-β amyloid form of peptides and proteins represents an archetypal and widely accessible structure consisting of ordered arrays of β-sheet filaments. These complex aggregates have remarkable chemical and physical properties, and the conversion of normally soluble functional forms of proteins into amyloid structures is linked to many debilitating human diseases, including several common forms of age-related dementia. Despite their importance, however, cross-β amyloid fibrils have proved to be recalcitrant to detailed structural analysis. By combining structural constraints from a series of experimental techniques spanning five orders of magnitude in length scale—including magic angle spinning nuclear magnetic resonance spectroscopy, X-ray fiber diffraction, cryoelectron microscopy, scanning transmission electron microscopy, and atomic force microscopy—we report the atomic-resolution (0.5 Å) structures of three amyloid polymorphs formed by an 11-residue peptide. These structures reveal the details of the packing interactions by which the constituent β-strands are assembled hierarchically into protofilaments, filaments, and mature fibrils. PMID:23513222

Selenium (Se) is an essential nutrient with diverse physiological functions. The selenium content of commonly consumed cereals, pulses and green leafy vegetables (GLV) was determined. Bioaccessibility of Se, and its organic forms selenomethionine (SeMet), and selenocysteine (SeCys2) was also examined, and the effect of heat processing on the same was studied. The bioaccessibility of Se in cereals ranged from 10% to 24%, that of pulses was between 12% and 29%, and of GLV, 10-31%. The concentration of SeMet in the dialysates of the cereals, pulses and GLV ranged from 5.15 to 28.7, 2.7 to 36.2, and 0.03 to 5ngg(-1), respectively. The concentration of SeCys2 in the dialysates of the foods examined was negligible. Heat processing significantly decreased the bioaccessibility of Se, SeMet and SeCys2. This is the first report on the bioaccessibility of Se and its major organic forms from commonly consumed staples, and the effect of heat processing on the same. Copyright © 2015 Elsevier Ltd.

Allelic genealogies in sporophytic self-incompatibility systems in plants.

PubMed

Schierup, M H; Vekemans, X; Christiansen, F B

1998-11-01

Expectations for the time scale and structure of allelic genealogies in finite populations are formed under three models of sporophytic self-incompatibility. The models differ in the dominance interactions among the alleles that determine the self-incompatibility phenotype: In the SSIcod model, alleles act codominantly in both pollen and style, in the SSIdom model, alleles form a dominance hierarchy, and in SSIdomcod, alleles are codominant in the style and show a dominance hierarchy in the pollen. Coalescence times of alleles rarely differ more than threefold from those under gametophytic self-incompatibility, and transspecific polymorphism is therefore expected to be equally common. The previously reported directional turnover process of alleles in the SSIdomcod model results in coalescence times lower and substitution rates higher than those in the other models. The SSIdom model assumes strong asymmetries in allelic action, and the most recessive extant allele is likely to be the most recent common ancestor. Despite these asymmetries, the expected shape of the allele genealogies does not deviate markedly from the shape of a neutral gene genealogy. The application of the results to sequence surveys of alleles, including interspecific comparisons, is discussed.

Choledocholithiasis is presence of stone in Common bile duct (CBD) which can be treated by endoscopy or surgery [1]. Retained foreign bodies like stents forms a nidus for stone formation resulting in pain, fever, jaundice. 60 years female patient admitted in surgery ward with features of cholangitis with computed tomography showing cholangitic abscess with dilated common bile duct and sludge around stent in situ. Stone was found at proximal end of stent during surgery. Stents may remain without complications or may migrate, and rarely form nidus for stone formation. If kept for long time they lead to bacterial proliferation, biofilm formation and precipitation of calcium bilirubinate presenting as fever, pain, jaundice. Stent-stone complex can be treated endoscopically and surgically [6,7]. As stent can cause stone formation, infection and other complications, timely removal of stent should advised. III-effects of stent in-situ should be explained, record should be maintained [8] and patient should be advised regular follow up and stent removal after 6 weeks. Copyright © 2016 The Authors.

Oligomycin frames a common drug-binding site in the ATP synthase

DOE Office of Scientific and Technical Information (OSTI.GOV)

Symersky, Jindrich; Osowski, Daniel; Walters, D. Eric

We report the high-resolution (1.9 {angstrom}) crystal structure of oligomycin bound to the subunit c10 ring of the yeast mitochondrial ATP synthase. Oligomycin binds to the surface of the c10 ring making contact with two neighboring molecules at a position that explains the inhibitory effect on ATP synthesis. The carboxyl side chain of Glu59, which is essential for proton translocation, forms an H-bond with oligomycin via a bridging water molecule but is otherwise shielded from the aqueous environment. The remaining contacts between oligomycin and subunit c are primarily hydrophobic. The amino acid residues that form the oligomycin-binding site are 100%more » conserved between human and yeast but are widely different from those in bacterial homologs, thus explaining the differential sensitivity to oligomycin. Prior genetics studies suggest that the oligomycin-binding site overlaps with the binding site of other antibiotics, including those effective against Mycobacterium tuberculosis, and thereby frames a common 'drug-binding site.' We anticipate that this drug-binding site will serve as an effective target for new antibiotics developed by rational design.« less

Modeling thermionic emission from laser-heated nanoparticles

DOE PAGES

Mitrani, J. M.; Shneider, M. N.; Stratton, B. C.; ...

2016-02-01

An adjusted form of thermionic emission is applied to calculate emitted current from laser-heated nanoparticles and to interpret time-resolved laser-induced incandescence (TR-LII) signals. This adjusted form of thermionic emission predicts significantly lower values of emitted current compared to the commonly used Richardson-Dushman equation, since the buildup of positive charge in a laser-heated nanoparticle increases the energy barrier for further emission of electrons. Thermionic emission influences the particle's energy balance equation, which can influence TR-LII signals. Additionally, reports suggest that thermionic emission can induce disintegration of nanoparticle aggregates when the electrostatic Coulomb repulsion energy between two positively charged primary particles ismore » greater than the van der Waals bond energy. Furthermore, since the presence and size of aggregates strongly influences the particle's energy balance equation, using an appropriate form of thermionic emission to calculate emitted current may improve interpretation of TR-LII signals.« less

Distribution of iodine into blood components of the Sprague-Dawley rat differs with the chemical form administered

NASA Technical Reports Server (NTRS)

Thrall, K. D.; Bull, R. J.; Sauer, R. L.

1992-01-01

It has been reported previously that radioactivity derived from iodine distributes differently in the Sprague-Dawley rat depending on the chemical form administered (Thrall and Bull, 1990). In the present communication we report the differential distribution of radioactivity derived from iodine (I2) and iodide (I-) into blood components. Twice as much radioiodine is in the form of I- in the plasma of animals treated with 125I- compared to 125I2-treated rats. No I2 could be detected in the plasma. With an increase in dose, increasing amounts of radioactivity derived from 125I2-treated animals distribute to whole blood compared to equivalent doses of 125I-, reaching a maxima at a dose of 15.8 mumol I/kg body weight. Most of the radioactivity derived from I2 associates with serum proteins and lipids, in particular with albumin and cholesteryl iodide. These data indicate a differential distribution of radioactivity depending on whether it is administered as iodide or iodine. This is inconsistent with the commonly held view that iodine (I2) is reduced to iodide (I-) before it is absorbed systemically from the gastrointestinal tract.

Using a nationally representative sample of adolescents from the United States aged 12 to 17 years (Wave 1, n = 3,614; Wave 2, n = 2,511), this study examined (a) demographic and descriptive information about peer violent victimization (PVV); and (b) the longitudinal relation between a history of PVV and delinquency. Results indicated that 12.4% of adolescents reported lifetime exposure to PVV, and many of these adolescents with a previous history of PVV also reported exposure to other forms of interpersonal violence, with witnessing community/school violence being the most commonly endorsed exposure category. Males, older adolescents, African American adolescents, and adolescents from low-income households were significantly more likely to endorse PVV. Regardless of the victim's gender, the majority of the perpetrators were male. After controlling for exposure to other forms of interpersonal violence and a history of delinquency, PVV was related to subsequent delinquency. Implications for policy, practice, and future research are discussed.

To describe the epidemiological profile of people living with disabilities due to traffic accidents (TA) in Peru. Secondary analysis of the National Survey Specialized on Disability (ENEDIS) of 2012 and an ecological analysis of TA records of the Ministry of Transportation and Communications was done. Disability by traffic accidents (DAT) was reported by 49,036 persons; 81.3% of whom live in urban areas. The most frequent disability was limited locomotion and skill (77.4%), followed by visual impairment (22.9%). Dependence for activities was reported in 44.7% of persons with disabilities. The regions with the highest prevalence of TA have a higher prevalence of disability by traffic accidents (Spearman coefficient: 0.426, p=0.034). Most of disability due to TA is found in urban areas, correspond to males and consist of persons in economically productive age. The most common form of disability is in locomotion. Most of individuals do not receive any form of rehabilitation, which accentuates health inequity related to traffic accidents.

Repair of segmental bone defects in the maxilla by transport disc distraction osteogenesis: Clinical experience with a new device

PubMed Central

Boonzaier, James; Vicatos, George; Hendricks, Rushdi

2015-01-01

The bones of the maxillary complex are vital for normal oro-nasal function and facial cosmetics. Maxillary tumor excision results in large defects that commonly include segments of the alveolar and palatine processes, compromising eating, speech and facial appearance. Unlike the conventional approach to maxillary defect repair by vascularized bone grafting, transport disc distraction osteogenesis (TDDO) stimulates new bone by separating the healing callus, and stimulates growth of surrounding soft tissues as well. Bone formed in this way closely mimics the parent bone in form and internal structure, producing a superior anatomical, functional and cosmetic result. Historically, TDDO has been successfully used to close small horizontal cleft defects in the maxilla, not exceeding 25 mm. Fujioka et al. reported in 2012 that “no bone transporter corresponding to the (large) size of the oro-antral fistula is marketed. The authors report the successful treatment of 4 cases involving alveolar defects of between 25 mm and 80 mm in length. PMID:26389041

Self-report is the most common means of obtaining mammography screening data. The purpose of this study was to assess the accuracy of minority women's self-reported mammography by comparing their self-reported dates of mammograms with those in their medical records from a community-based randomized control trial. We found that out of 192 women, 116 signed the Health Information Portability and Accountability Act form and, among these, 97 had medical records that could be verified (97 / 116 = 83.6%). Ninety-two records matched where both sources confirmed a mammogram; 48 of 92 (52.2%) matched perfectly on self-reported date of mammogram. Complexities in the verification process warrant caution when verifying self-reported mammography screening in minority populations. In spite of some limitations, our findings support the usage of self-reported data on mammography as a validated tool for other researchers investigating mammography screening among minority women who continue to have low screening rates. © The Author(s) 2016.

The clinical history and histological features of seven cases of granulomatous mastitis are presented. The lesion occurs in young parous women as a tender extra-areolar breast lump. Histologically, non-caseating discrete granulomas are present, confined to breast lobules with, in three cases, coalescence of the granulomas and microabscess formation. Pathogenesis of the changes is discussed. It is thought that granulomatous mastitis is an entity morphologically distinct from duct ectasia/plasma cell mastitis and the commoner forms of granulomatous breast diseases. Images PMID:6889612

Sporotrichosis is a subcutaneous mycotic infection caused by Sporothrix schenckii, a group of common saprophytes of soil, plants, and organic debris. Disseminated forms may be seen in the setting of immunosuppression and are typically treated initially with intravenous lipidized amphotericin B. We report an unusual case of a 65-year-old woman who developed disseminated cutaneous sporotrichosis with extensive facial involvement in the absence of a known primary inoculation. Her cutaneous lesions completely resolved after treatment with intravenous posaconazole without amphotericin B.

Sphaerosiderite, a morphologically distinct millimeter-scale spherulitic siderite (FeCO3), forms predominantly in wetland soils and sediments, and is common in the geologic record. Ancient sphaerosiderites are found in paleosol horizons within coal-bearing stratigraphic intervals and, like their modern counterparts, are interpreted as having formed in water-saturated environments. Here we report on sphaerosiderites from four different stratigraphic units, each of which has highly variable 13C and relatively stable 18O compositions. The unique isotopic trends are analogous to well-documented meteoric calcite lines, which we define here as meteoric sphaerosiderite lines. Meteoric sphaerosiderite lines provide a new means of constraining ground-water ??18O and thus allow evaluation of paleohydrology and paleoclimate in humid continental settings.

Complementary and alternative medicine use by visitors to rural Japanese family medicine clinics: results from the international complementary and alternative medicine survey.

There is growing interest in the use of complementary and alternative medicine (CAM) throughout the world, however previous research done in Japan has focused primarily on CAM use in major cities. The purpose of this study was to develop and distribute a Japanese version of the International Complementary and Alternative Medicine Questionnaire (I-CAM-Q) to assess the use of CAM among people who visit rural Japanese family medicine clinics. Using a Japanese version of the International Complementary and Alternative Medicine Questionnaire (I-CAM-Q), a cross-sectional survey was conducted in three rural family medicine clinics. All patients and those accompanying patients who met inclusion criteria were eligible to participate. Data were entered into SPSS Statistics and analyzed for use by age, gender, and location. Of the 519 respondents who participated in the project, 415 participants reported CAM use in the past 12 months (80.0%). When prayer is excluded, the prevalence of CAM use drops to 77.3% in the past year, or 403 respondents. The most common forms of CAM used by respondents were pain relief pads (n = 170, 32.8%), herbal medicines/supplements (n = 167, 32.2%), and massage by self or family (n = 166, 32.0%). Female respondents, individuals with higher levels of education, and those with poorer overall health status were more likely to use CAM than respondents without these characteristics. Only 22.8% of CAM therapies used were reported to physicians by survey participants. These data indicate that CAM use in rural Japan is common. The results are consistent with previous studies that show that Japanese individuals are more interested in forms of CAM such as pain relief pads and massage, than in mind-body forms of CAM like relaxation and meditation. Due to the high utilization of certain CAM practices, and given that most CAM users do not disclose their CAM use to their doctors, we conclude that physicians in rural Japan would benefit by asking about CAM use during patient interviews, and by familiarizing themselves with the potential benefits and risks of commonly used CAM modalities.

Haemophilus influenzae is a common cause of bacterial meningitis in children and can cause upper respiratory tract infections in adults, but has yet to be reported solely involving intervertebral discitis. A 67-year-old builder presenting with fever, myalgia and back pain is found to have intervertebral discitis (confirmed on MRI) caused by H. influenzae (identified on blood cultures). A nontypeable form of H. influenzae has not been reported causing discitis. We describe a case in a relatively fit individual who was treated successfully with antimicrobial treatment. A preceding upper respiratory tract infection is the presumed source of infection, predisposed by long-term low-dose steroid therapy. H. influenzae is a rare, but treatable cause of discitis.

Clinically relevant renal lesions in rheumatoid arthritis (RA) are not common. More often renal involvement is related to complications of therapy than the disease itself. The most common forms of primary renal disease in RA are membranous glomerulonephropathy and a pure mesangial proliferative glomerulonephritis. Some studies have described the association between crescentic glomerulonephritis (crescentic GN) and RA, but they were all found to be perinuclear antineutrophil cytoplasmic antibody (p-ANCA) positive. However, RA associated with ANCA negative pauci-immue crescentic GN has not been reported. This is a case report of a 37-year-old female with RA who initially presented with general oedema and acute deterioration of renal function. The renal biopsy revealed ANCA negative pauci-immune crescentic GN. The patient was treated with steroid pulse and plasmapheresis, but not cyclophosphamide because of severe urosepsis. Despite the use of aggressive therapy, her renal function was not improved and she underwent maintenance haemodialysis thereafter. Because ANCA negative crescentic GN may occur in RA patients without frank systemic vasculitis, but with severe clinical manifestation, a heightened suspicion for a relatively 'silent' crescentic GN would have led to the correct diagnosis and appropriate treatment.

To know the situation of tobacco advertisement, promotions and related factors in six cities in China. 4815 adults (above 18 years), selected form Beijing, Shanghai, Shenyang, Changsha, Guangzhou and Yinchuan through probability proportionate sampling and simple random sampling, were investigated through questionnaires. The most commonly reported channels that smokers noticed tobacco advertisements were billboards (35.6%) and television (34.4%). The most commonly reported tobacco promotional activities that were noticed by smokers were free gifts when buying cigarettes (23.1%) and free samples of cigarettes (13.9%). Smokers in Changsha were more likely to report noticing tobacco advertisement on billboards (chi2 = 562.474, P < 0.00 1), and on television (chi2 = 265.570, P < 0.001). Smokers in Changsha (chi2 = 58.314, P < 0.001) were more likely to notice tobacco related news and games. A logistic regression analysis showed that the living and education level were related to awareness of tobacco advertisement and promotion. It was universal to see tobacco advertisement and promotions in cities in China but the laws and regulations about tobacco-control were not uniformly executed in different cities. It is necessary to perfect and uniform related laws and regulations.

Background Globally many doctors, particularly in low-income countries, have no formal training in using new information to improve their practice. As a first step clinicians must have access to information and so we explored reported access in graduating medical students in Nairobi. Objectives To evaluate final year medical students’ access to new medical information. Methods A cross-sectional survey of fifth (final) year medical students at the University of Nairobi using anonymous, self-administered questionnaires. Findings Questionnaires were distributed to 291 (85%) of a possible 343 students and returned by 152 (44%). Within the previous 12 months half reported accessing some form of new medical information most commonly from books and the internet. However, only a small number reported regular access and specific, new journal articles were rarely accessed. Absence of internet facilities, slow internet speeds and cost were common barriers to access while current training seems rarely to encourage students to seek new information. Conclusion Almost half the students had not accessed any new medical information in their final year in medical school suggesting they are ill prepared for a career that may increasingly demand life-long, self-learning.

We report here the genetic basis for a form of progressive hereditary spastic paraplegia (SPG43) previously described in two Malian sisters. Exome sequencing revealed a homozygous missense variant (c.187G>C; p.Ala63Pro) in C19orf12, a gene recently implicated in neurodegeneration with brain iron accumulation (NBIA). The same mutation was subsequently also found in a Brazilian family with features of NBIA, and we identified another NBIA patient with a three-nucleotide deletion (c.197_199del; p.Gly66del). Haplotype analysis revealed that the p.Ala63Pro mutations have a common origin, but MRI scans showed no brain iron deposition in the Malian SPG43 subjects. Heterologous expression of these SPG43 and NBIA variants resulted in similar alterations in the subcellular distribution of C19orf12. The SPG43 and NBIA variants reported here as well as the most common C19orf12 missense mutation reported in NBIA patients are found within a highly-conserved, extended hydrophobic domain in C19orf12, underscoring the functional importance of this domain.

Psoriasis is a frequent skin inflammatory disorder that inflicts millions of patients around the globe. To meet their healthcare needs, patients with psoriasis often seek treatment outside the allopathic paradigm. Use of medicinal plants has emerged as one of the most common and preferred modalities of complementary and alternative medicine (CAM). The aim of this study was to investigate the use of medicinal plants by patients with psoriasis in the West Bank of Palestine. The current study was a questionnaire based cross-sectional descriptive study on the use of medicinal plants by psoriasis patients in the West Bank of Palestine. A sample of 149 patients with psoriasis who were visiting outpatient clinics responded to the questionnaire in face to face interviews. Medicinal plants were used by 81 (54.4%) patients with psoriasis. Patients used 33 medicinal plants belonging to 26 families. Plants belonging to Lamiaceae and Leguminosae were the most commonly used by the study patients. Aloe vera, Trigonella arabica, Catharanthus roseus and Anthemis cotula were the most frequently used medicinal plants to treat psoriasis. Leaves and fruits were the most commonly used parts by the study patients. Paste was the most commonly used form of preparation. The use of medicinal plants was significantly associated with age and monthly household income of the patients. Enhancement of immunity, improving conventional therapy and reduction of side effects were the most commonly self-reported reasons for using medicinal plants. Patients with psoriasis in Palestine seem to use medicinal plants as a CAM modality to manage their psoriasis. Many medicinal plants were commonly used by patients with psoriasis. More randomized clinical trials are needed to demonstrate safety and efficacy for the majority of these medicinal plants reported to be used by patients with psoriasis in Palestine.

The study includes cases resulting in a forensic report among all traumatic patients presenting to the ED of Adiyaman University Training and Research Hospital, Adiyaman, Turkey during a 1-year period. We recorded the demographic characteristics of all the cases, time of presentation to the ED, traumatic characteristics of medico-legal cases, forms of suicide attempt, suspected poisonous substance exposure, the result of follow-up and the type of forensic report. A total of 4300 traumatic medico-legal cases were included in the study and 72% of these cases were male. Traumatic medico-legal cases occurred at the greatest frequency in July (10.1%) and 28.9% of all cases occurred in summer. The most frequent causes of traumatic medico-legal cases in the ED were traffic accidents (43.4%), violent crime (30.5%), and suicide attempt (7.2%). The most common method of attempted suicide was drug intake (86.4%). 12.3% of traumatic medico-legal cases were hospitalized and 24.2% of those hospitalized were admitted to the orthopedics service. The most common error in forensic reports was the incomplete recording of the patient's "cooperation" status (82.7%). Additionally, external traumatic lesions were not defined in 62.4% of forensic reports. The majority of traumatic medico-legal cases were male age 18-44 years, the most common source of trauma was traffic accidents and in the summer months. When writing a forensic report, emergency physicians made mistakes in noting physical examination findings and identifying external traumatic lesions. Physicians should make sure that the traumatic medico-legal patients they treat have adequate documentation for reference during legal proceedings. The legal duties and responsibilities of physicians should be emphasized with in-service training.

Medicinal and Environmental Indicator Species of Utricularia from Montane Forest of Peninsular Malaysia

The carnivorous Utricularia (Lentibulariaceae) is a small herb of multifarious wet habitats worldwide. Eleven of the 14 Peninsular Malaysian species range into the mountains. Distribution, disturbance adaptability and collection frequency were used to formulate their commonness category. Common (U. aurea, U. bifida, and U. minutissima) and fairly common (U. gibba and U. uliginosa) species are mostly lowland plants that ascend to open montane microhabitats, while the fairly common (U. striatula), narrow-range (U. caerulea pink form and U. involvens), rare (U. furcellata and U. scandens), and endemic (U. vitellina) species are restricted to mountainous sites. Common species that colonise dystrophic to oligotrophic man-made sites in late succession could serve as predictors for general health and recovery of wet habitats. Rarer species are often locally abundant, their niches situated around pristine forest edges. When in decline, they indicate the beginning of problems affecting the forest. Utricularia is reportedly nutritious, mildly astringent, and diuretic. Preadapted to nutrient-poor, waterlogged soils, U. bifida is suitable as an alternative for small-scale herb cultivation on low pH, wet poor soils usually deemed not suitable for any crops.

2016-06-01

A 2-month-old Pacific parrotlet (Forpus coelestis) was presented for assessment following a traumatic injury to the right wing that resulted in persistent swelling and inflammation. Six weeks postinjury the bird underwent surgical resection of a large hemorrhagic cavitated mass that had formed at the site of the original injury and a second, smaller mass on the body in direct contact with the wing mass. Histopathology of the wing mass confirmed a diagnosis of hemangiosarcoma. While commonly diagnosed in domestic species, hemangiosarcoma is uncommonly reported in avian species. To the authors' knowledge, this is the first report of hemangiosarcoma in a Pacific parrotlet and describes the development of hemangiosarcoma in a psittacine bird following trauma-induced inflammation.

Familial atrophia maculosa varioliformis cutis.

2003-07-01

Atrophia maculosa varioliformis cutis (AVMC) was first described by Heidingsfeld in 1918, as a rarely reported form of idiopathic macular atrophy on the cheek (1). It is characterized, clinically, by shallow, sharply demarcated depressions in various shapes. Extrahepatic biliary atresia (2) and pachydermodactyly (3) have been the only conditions associated with AMVC reported in the past 80 years. Although keratosis pilaris is a common skin disorder, it is related to other idiopathic atrophic conditions considered in the differential diagnosis of AMVC, namely keratosis pilaris atrophicans (4). However, the two associations may be coincidental. We observed a patient with keratosis pilaris, and her brother and an unrelated young man, whose findings led to a diagnosis of AMVC.

Periocular necrotizing fasciitis is a rare but potentially devastating disease, accompanied by high rates of morbidity and mortality. We report 5 cases of periocular necrotizing fasciitis resulting in severe vision loss, 3 of which required exenteration to contain the disease and only 1 of which recovered vision. Three cases were caused by group A streptococcus; 1, by methicillin-resistant Staphylococcus aureus; and 1, by Streptococcus anginosus constellatus. Providers should maintain a high clinical suspicion for necrotizing fasciitis and distinguish it from more common forms of cellulitis. As seen in these 5 cases, periocular necrotizing fasciitis may cause severe visual loss more often than previously recognized. To our knowledge, this is also the first report of Streptococcus anginosus constellatus causing necrotizing fasciitis.

In October 1980, a National Civil Defence Planning Committee on Volcanic Hazards was formed in New Zealand, and solicited reports on the likely areas and types of future eruptions, the risk to public safety, and the need for special precautions. Reports for eight volcanic centres were received, and made available to the authors. This paper summarises and quantifies the type and frequency of hazard, the public risk, and the possibilities for mitigation at the 7 main volcanic centres: Northland, Auckland, White Island, Okataina, Taupo, Tongariro, and Egmont. On the basis of Recent tephrostratigraphy, eruption probabilities up to 20% per century (but commonly 5%), and tephra volumes up to 100 km 3 are credible.

Field Programmable Gate Arrays commonly called FPGA's are the newer generation of field programmable devices and offer more flexibility in the logic modules they incorporate and in how they are interconnected. The flexibility, the number of logic building blocks available, and the high gate densities achievable are why users find FPGA's attractive. These attributes are important in reducing product development costs and shortening the development cycle. The aerospace community is interested in incorporating this new generation of field programmable technology in space applications. To this end, a consortium was formed to evaluate the quality, reliability, and radiation performance of FPGA's. This report presents the test results on FPGA parts provided by ACTEL Corporation.

2017-01-16

Parthenogenesis is a natural form of asexual reproduction in which embryos develop in the absence of fertilisation. Most commonly found in plants and invertebrate organisms, an increasing number of vertebrate species have recently been reported employing this reproductive strategy. Here we use DNA genotyping to report the first demonstration of an intra-individual switch from sexual to parthenogenetic reproduction in a shark species, the zebra shark Stegostoma fasciatum. A co-housed, sexually produced daughter zebra shark also commenced parthenogenetic reproduction at the onset of maturity without any prior mating. The demonstration of parthenogenesis in these two conspecific individuals with different sexual histories provides further support that elasmobranch fishes may flexibly adapt their reproductive strategy to environmental circumstances.

Fasciola hepatica, a leaf shaped trematode that is common in cattle, sheep and goats, is acquired by eating raw water plants like watercress or drinking water infected with the encysted form of the parasite. The varied clinical presentations of fascioliasis still make a high index of suspicion mandatory. Besides having a wide spectrum of hepatobiliary symptoms like obstructive jaundice, cholangitis and liver cirrhosis, the parasitic infection also has extrabiliary manifestations. Until recently, extrahepatic fascioliasis has been reported in the subcutaneous tissue, brain, lungs, epididymis, inguinal lymph nodes, stomach and the cecum. In this report, a strange manifestation of the fasciola infection in a site other than the liver, a colonic fascioliasis, is presented. PMID:17552017

2016-02-01

Alport Syndrome is a hereditary disease that is caused by a gene mutation and affects the production of collagen in basement membranes; this condition causes hemorrhagic nephritis associated with deafness and ocular changes. The X-linked form of this disease is the most common and mainly affects males. Typical ocular findings are dot-and-fleck retinopathy, anterior lenticonus, and posterior polymorphous corneal dystrophy. Some cases involving polymorphous corneal dystrophy and corneal ectasia have been previously described. Here we present a case report of a 33-year-old female with Alport syndrome, posterior polymorphous corneal dystrophy, and irregular astigmatism, whose visual acuity improved with a rigid gas permeable contact lens.

Mollaret's meningitis is a rare form of benign recurrent aseptic meningitis first described in 1944. We report a case of Mollaret's meningitis due to Herpes Simplex Virus type 2 (HSV2), diagnosed with Polymerase Chain Reaction (PCR) implementation in the Cerebrospinal fluid (CSF) of the patient and treated successfully with acyclovir. To our knowledge, this is the first case of Mollaret's meningitis reported in Greece. We reviewed the literature since PCR has become widely available. Herpes Simplex Virus type 2 has been the most commonly identified causative agent of Mollaret's meningitis. Copyright © 2010 King Saud Bin Abdulaziz University for Health Sciences.

Henningsen, Peter; Jakobsen, Thorsten; Schiltenwolf, Marcus; Weiss, Mitchell G

2005-02-01

The assessment of somatoform disorders is complicated by persistent theoretical and practical questions of classification and assessment. Critical rethinking of professional concepts of somatization suggests the value of complementary assessment of patients' illness explanatory models of somatoform and other common mental disorders. We undertook this prospective study to assess medically unexplained somatic symptoms and their patient-perceived causes of illness and to show how patients' explanatory models relate to professional diagnoses of common mental disorders and how they may predict the short-term course of illness. Tertiary care patients (N=186) with prominent somatoform symptoms were evaluated with the Structured Clinical Interview for DSM-IV, a locally adapted Explanatory Model Interview to elicit patients' illness experience (priority symptoms) and perceived causes, and clinical self-report questionnaires. The self-report questionnaires were administered at baseline and after 6 months. Diagnostic overlap between somatoform, depressive, and anxiety disorders occurred frequently (79.6%). Patients explained pure somatoform disorders mainly with organic causal attributions; they explained pure depressive and/or anxiety disorders mainly with psychosocial perceived causes, and patients in the diagnostic overlap group typically reported mixed causal attributions. In this last group, among patients with similar levels of symptom severity, organic perceived causes were related to a lower physical health sum score on the MOS Short Form, and psychosocial perceived causes were related to less severe depressive symptoms, assessed with the Hospital Anxiety and Depression Scale at 6 months. Among patients meeting criteria for comorbid somatoform with anxiety and/or depressive disorders, complementary assessment of patient-perceived causes, a key element of illness explanatory models, was related to levels of functional impairment and short-term prognosis. For such patients, causal attributions may be particularly useful to clarify clinically significant features of common mental disorders and thereby contribute to clinical assessment.

The mycotoxin deoxynivalenol (DON) is one of the most common mycotoxins of cereals worldwide, and its occurrence has been widely reported in raw wheat. The free mycotoxin form is not the only route of exposure; modified forms can also be present in cereal products. Deoxynivalenol-3-glucoside (DON-3-glucoside) is a common DON plant conjugate. The mycotoxin concentration could be affected by food processing; here, we studied the stability of DON and DON-3-glucoside during baking of small doughs made from white wheat flour and other ingredients. A range of common food additives and ingredients were added to assess possible interference: ascorbic acid (E300), citric acid (E330), sorbic acid (E200), calcium propionate (E282), lecithin (E322), diacetyltartaric acid esters of fatty acid mono- and diglycerides (E472a), calcium phosphate (E341), disodium diphosphate (E450i), xanthan gum (E415), polydextrose (E1200), sorbitol (E420i), sodium bicarbonate (E500i), wheat gluten and malt flour. The DON content was reduced by 40%, and the DON-3-glucoside concentration increased by >100%, after baking for 20 min at 180°C. This confirmed that DON and DON-3-glucoside concentrations can vary during heating, and DON-3-glucoside could even increase after baking. However, DON and DON-3-glucoside are not affected significantly by the presence of the food additives tested.

Alpha thalassaemia is a highly prevalent disease globally and is a well-known public health problem in Malaysia. The deletional forms of the mutation are the most common forms found in alpha thalassaemia. The three most common deletional alpha thalassaemia found in this region include --(SEA) deletion, -α(3.7) rightward and -α(4.2) leftward deletions. The prevalence rate of triplication alpha cases such as ααα(anti3.7) and ααα(anti4.2) is not known in Malaysia although it plays a role in exacerbating the clinical phenotypes in beta thalassaemia carriers. Recently, there have been more reported cases of rare alpha thalassaemia mutations due to the advancement of molecular techniques involved in thalassaemia detections. Therefore, it is essential to develop a new method which allows the detection of different alpha thalassaemia mutations including the rare ones simultaneously and accurately. The purpose of this study was to design an assay for the detection of triplications, common and rare deletional alpha thalassaemia using droplet digital PCR (ddPCR). This is a quantitative detection method to measure the changes of copy number which can detect deletions, duplications and triplications of the alpha globin gene simultaneously. In conclusion, ddPCR is an alternative method for rapid detection of alpha thalassaemia variants in Malaysia. © 2016 John Wiley & Sons Ltd.

High Abundance of Ions in Cosmic Ices

2002-01-01

Water-rich, mixed molecular ices and polycyclic aromatic hydrocarbons (PAHs) are common throughout interstellar molecular clouds and the Solar System. Vacuum ultraviolet (VUV) irradiation and particle bombardment of these abiotic ices produces complex organic species, including important biogenic molecules such as amino acids and functionalized PAHs which may have played a role in the origin of life. This ability of such water-rich, oxygen dominated ices to promote production of complex organic species is surprising and points to an important, unusual, but previously overlooked mechanism at play within the ice. Here we report the nature of this mechanism using electronic spectroscopy. VUV-irradiation of PAH/H2O ices leads to an unprecedented and efficient (greater than 70 %) conversion of the neutral PAHs to their cation form (PAH+). Further, these H2O/PAH+ ices are stabile at temperatures below 50 K, a temperature domain common throughout interstellar clouds and the Solar System. Between 50 and 125 K they react to form the complex organics. In view of this, we conclude that charged PAHs and other molecular ions should be common and abundant in many cosmic ices. The chemical, spectroscopic and physical properties of these ion-rich ices can be of fundamental importance for objects as diverse as comets, planets, and molecular clouds and may account for several poorly understood phenomena associated with each of these object classes.

Maternal Impression Management in the Assessment of Childhood Depressive Symptomatology.

Lilly, Megan; Davis, Thompson E; Castagna, Peter J; Marker, Arwen; Davis, Allison B

2018-02-27

Self-report instruments are commonly used to assess for childhood depressive symptoms. Historically, clinicians have relied heavily on parent-reports due to concerns about childrens' cognitive abilities to understand diagnostic questions. However, parents may also be unreliable reporters due to a lack of understanding of their child's symptomatology, overshadowing by their own problems, and tendencies to promote themselves more favourably in order to achieve desired assessment goals. One such variable that can lead to unreliable reporting is impression management, which is a goal-directed response in which an individual (e.g. mother or father) attempts to represent themselves, or their child, in a socially desirable way to the observer. This study examined the relationship between mothers who engage in impression management, as measured by the Parenting Stress Index-Short Form defensive responding subscale, and parent-/child-self-reports of depressive symptomatology in 106 mother-child dyads. 106 clinic-referred children (mean child age = 10.06 years, range 7-16 years) were administered the Child Depression Inventory, and mothers (mean mother age = 40.80 years, range 27-57 years) were administered the Child-Behavior Checklist, Parenting Stress Index-Short Form, and Symptom Checklist-90-Revised. As predicted, mothers who engaged in impression management under-reported their child's symptomatology on the anxious/depressed and withdrawn subscales of the Child Behavior Checklist. Moreover, the relationship between maternal-reported child depressive symptoms and child-reported depressive symptoms was moderated by impression management. These results suggest that children may be more reliable reporters of their own depressive symptomatology when mothers are highly defensive or stressed.

Evidence for Gender-Dependent Genotype by Environment Interaction in Adult Depression.

Depression in adults is heritable with about 40 % of the phenotypic variance due to additive genetic effects and the remaining phenotypic variance due to unique (unshared) environmental effects. Common environmental effects shared by family members are rarely found in adults. One possible explanation for this finding is that there is an interaction between genes and the environment which may mask effects of the common environment. To test this hypothesis, we investigated genotype by environment interaction in a large sample of female and male adult twins aged 18-70 years. The anxious depression subscale of the Adult Self Report from the Achenbach System of Empirically Based Assessment (Achenbach and Rescorla in Manual for the ASEBA adult: forms and profiles, 2003) was completed by 13,022 twins who participate in longitudinal studies of the Netherlands Twin Register. In a single group analysis, we found genotype by unique environment interaction, but no genotype by common environment interaction. However, when conditioning on gender, we observed genotype by common environment interaction in men, with larger common environmental variance in men who are genetically less at risk to develop depression. Although the effect size of the interaction is characterized by large uncertainty, the results show that there is at least some variance due to the common environment in adult depression in men.

Summary Osteogenesis imperfecta (OI) is a rare hereditary disease caused by mutations in genes coding for type I collagen, resulting in bone fragility. In literature are described forms lethal in perinatal period, forms which are moderate and slight forms where the only sign of disease is osteopenia. Child abuse is an important social and medical problem. Fractures are the second most common presentation after skin lesions and may present specific patterns. The differential diagnosis between slight-moderate forms of OI and child abuse could be very challenging especially when other signs typical of abuse are absent, since both could present with multiple fractures without reasonable explanations. We report a 20 months-old female with a history of 4 fractures occurred between the age of three and eighteen months, brought to authorities’ attention as a suspected child abuse. However when she came to our department physical examination, biochemical tests, total body X-ray and a molecular analysis of DNA led the diagnosis of OI. Thus, a treatment with bisphosphonate and a physical rehabilitation process, according to Vojta method, were started with improvement in bony mineralization, gross motor skills and absence of new fracture. In conclusion our case demonstrates how in any child presenting fractures efforts should be made to consider, besides child abuse, all the other hypothesis even the rarest as OI. PMID:23289038

A silicone elastomer vaginal ring providing sustained release over 28 days of the anti-retroviral microbicide dapivirine has recently completed phase III clinical testing and showed moderate protection against HIV acquisition. In support of the product licensure program, we report the impact of dapivirine packing polymorphism on the thermal and solubility characteristics of dapivirine and on the in vitro performance of the 25 mg dapivirine ring product. This is the first time that polymorphism has been reported for a drug-releasing vaginal ring product. Thermal, particle size, powder X-ray diffraction, and thermodynamic solubility analyses of dapivirine polymorphic forms I and IV, both of which are persistent at room temperature and with form I being the thermodynamically stable form, were conducted for both micronized and non-micronized materials. No significant differences in solubility between DPV forms I and IV were observed in media commonly used for in vitro release testing. Matrix-type silicone elastomer vaginal rings were manufactured and the impact of dapivirine polymorphism on key in vitro parameters (compression and tensile behavior; content assay; in vitro release; residual content assay) was investigated. The data demonstrate that dapivirine packing polymorphism has no significant impact on in vitro performance of the 25 mg dapivirine vaginal ring. Copyright © 2017 American Pharmacists Association®.

"I am going to groom you": Multiple forms of play fighting in gray mouse lemurs (Microcebus murinus).

PubMed

Pellis, Sergio M; Pellis, Vivien C

2018-02-01

Play fighting is a commonly reported form of play that involves competitive interactions that generally do not escalate to serious fighting. Although in many species what are competed over are the body targets that are bitten or struck in serious fighting, for many others, the competition can be over other forms of contact, such as sex, social grooming, and predation. In primates, the most detailed studies have been of species such as Old World monkeys, that engage in play fighting that simulates serious fighting, but reports of a number of others, especially among nocturnal prosimians, have noted that play fighting can also involve simulation of sex and grooming. The present study on captive born gray mouse lemurs ( Microcebus murinus ) provides a quantitative assessment of the relative engagement by juveniles in play fighting involving agonistic and amicable targets. About 80% of play fighting involves competing to groom or mount one another, with a minority involving competing to bite. That these forms of play fighting may be distinct from one another is suggested by the finding that attack on one target does not lead to counterattack on another. The findings are discussed in terms of the evolution and mechanisms underlying play fighting in primates and more widely among animals. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Identification of a Unique Amyloid Sequence in AA Amyloidosis of a Pig Associated With Streptococcus Suis Infection.

Here we report a pig with amyloid A (AA) amyloidosis associated with Streptococcus suis infection and identification of a unique amyloid sequence in the amyloid deposits in the tissue. Tissues from the 180-day-old underdeveloped pig contained foci of necrosis and suppurative inflammation associated with S. suis infection. Congo red stain, immunohistochemistry, and electron microscopy revealed intense AA deposition in the spleen and renal glomeruli. Mass spectrometric analysis of amyloid material extracted from the spleen showed serum AA 2 (SAA2) peptide as well as a unique peptide sequence previously reported in a pig with AA amyloidosis. The common detection of the unique amyloid sequence in the current and past cases of AA amyloidosis in pigs suggests that this amyloid sequence might play a key role in the development of porcine AA amyloidosis. An in vitro fibrillation assay demonstrated that the unique AA peptide formed typically rigid, long amyloid fibrils (10 nm wide) and the N-terminus peptide of SAA2 formed zigzagged, short fibers (7 nm wide). Moreover, the SAA2 peptide formed long, rigid amyloid fibrils in the presence of sonicated amyloid fibrils formed by the unique AA peptide. These findings indicate that the N-terminus of SAA2 as well as the AA peptide mediate the development of AA amyloidosis in pigs via cross-seeding polymerization.

Context: Polycystic ovary syndrome (PCOS) is common among women of childbearing age and the available pharmacological therapies have different side-effect profiles. Objective: We summarized the evidence about the side effects of oral contraceptive pills, metformin, and anti-androgens in women with PCOS. Data Source: Sources included Ovid Medline, OVID EMBASE, OVID Cochrane Library, Web of Science, Scopus, PsycInfo, and CINAHL from inception through April 2011. Study Selection: We included comparative observational studies enrolling women with PCOS who received the agents of choice for at least 6 months and reported adverse effects. Data Extraction: Using a standardized, piloted, and Web-based data extraction form and working in duplicate, we abstracted data from each study and performed meta-analysis when possible. Data Synthesis: We found 22 eligible studies of which 20 were randomized. No study reported severe side effects (eg, lactic acidosis, thromboembolic episodes, liver toxicity, cancer incidence, or pregnancy loss). Meta-analysis demonstrated no significant change in weight in oral contraceptive pills or flutamide users. Indirect evidence from populations without PCOS demonstrated no increased risk of lactic acidosis with metformin, only case reports of liver toxicity with flutamide (no comparative evidence), and increased relative risk difference of venous thromboembolism with oral contraceptive pills but very low absolute risk. Evidence on mortality, cardiovascular mortality, and cancer was inconclusive. Conclusions: Drugs commonly used to treat PCOS appear to be associated with very low risk of severe adverse effects although data are extrapolated from other populations. PMID:24092830

2011-03-01

Gastro-esophageal reflux disease (GERD) is the most common digestive disease in industrialized countries (Europe and North America) and is associated with microscopic changes in the squamous epithelium. However, biopsy is not presently included in the routine diagnostic flow chart of GERD. In contrast, esophageal biopsy is mandatory when diagnosing Barrett's esophagus. High quality histology reports are necessary to provide information on diagnosis and can also be important for research and epidemiological studies. It has been evident for decades that pathology reports vary between institutions and even within a single institution. Standardization of reporting is the best way to ensure that information necessary for patient management is included in pathology reports. This paper details the histological criteria for diagnosing GERD-associated microscopic esophagitis, other forms of esophagitis with specific features and columnar metaplasia in the lower esophagus (Barrett's esophagus). It provides a detailed description of appropriate sampling criteria, individual lesions and how they contribute to the histology report. Copyright © 2011 Editrice Gastroenterologica Italiana S.r.l.

Finger drop sign-Characteristic pattern of distal weakness in Guillain-Barré Syndrome: A case report and review of the literature.

PubMed

Chee, Yong Chuan; Ong, Beng Hooi

2018-01-01

Guillain-Barré Syndrome is an acquired acute autoimmune polyradiculoneuropathy that commonly presents with limb weakness and occasional cranial nerve, respiratory and autonomic involvement. Although the classic description of Guillain-Barré Syndrome is that of a demyelinating neuropathy with ascending weakness, predominant bilateral finger drop as presenting feature has rarely been reported. A characteristic pattern of weakness involving the extensor components of the fingers known as "finger drop sign" has been first described to be specific in acute motor axonal neuropathy form of Guillain-Barré Syndrome in the literature. We report a case of acute motor-sensory axonal neuropathy, which showed characteristic pattern of predominant finger extensor weakness, and provide a summary of all reported cases to date. While previous reports suggested that this is a sign that carries good prognosis, our case report suggested otherwise as the patient succumbed to respiratory and autonomic complications. Further studies are needed to evaluate the clinical significance of this peculiar sign.

The development of food allergy is an increasingly recognized form of morbidity after solid organ transplant. It occurs more commonly in liver transplant recipients, although it has also been reported in heart, lung, kidney, and intestinal transplants. Pediatric transplant recipients are more likely to develop symptoms compared to adults, and reports of frequency vary widely from 5% to 38% in pediatric liver transplant recipients. Multiple mechanisms have been proposed in the literature, although no single mechanism can yet account for all reported observations. As food allergy can have at worst potentially fatal consequences, and at best require lifestyle adjustment through food avoidance, it is important for recipients to be aware of the donor's food allergies and particularly in pediatrics, the possibility of completely de novo allergies. This review explores the recent reports surrounding food allergy after solid organ transplant, including epidemiology, proposed mechanisms, and implications for practice. © 2015 John Wiley & Sons A/S.

NASA Interactive Forms Type Interface - NIFTI

Jain, Bobby; Morris, Bill

2005-01-01

A flexible database query, update, modify, and delete tool was developed that provides an easy interface to Oracle forms. This tool - the NASA interactive forms type interface, or NIFTI - features on-the- fly forms creation, forms sharing among users, the capability to query the database from user-entered criteria on forms, traversal of query results, an ability to generate tab-delimited reports, viewing and downloading of reports to the user s workstation, and a hypertext-based help system. NIFTI is a very powerful ad hoc query tool that was developed using C++, X-Windows by a Motif application framework. A unique tool, NIFTI s capabilities appear in no other known commercial-off-the- shelf (COTS) tool, because NIFTI, which can be launched from the user s desktop, is a simple yet very powerful tool with a highly intuitive, easy-to-use graphical user interface (GUI) that will expedite the creation of database query/update forms. NIFTI, therefore, can be used in NASA s International Space Station (ISS) as well as within government and industry - indeed by all users of the widely disseminated Oracle base. And it will provide significant cost savings in the areas of user training and scalability while advancing the art over current COTS browsers. No COTS browser performs all the functions NIFTI does, and NIFTI is easier to use. NIFTI s cost savings are very significant considering the very large database with which it is used and the large user community with varying data requirements it will support. Its ease of use means that personnel unfamiliar with databases (e.g., managers, supervisors, clerks, and others) can develop their own personal reports. For NASA, a tool such as NIFTI was needed to query, update, modify, and make deletions within the ISS vehicle master database (VMDB), a repository of engineering data that includes an indentured parts list and associated resource data (power, thermal, volume, weight, and the like). Since the VMDB is used both as a collection point for data and as a common repository for engineering, integration, and operations teams, a tool such as NIFTI had to be designed that could expedite the creation of database query/update forms which could then be shared among users.

Reference Avionics Architecture for Lunar Surface Systems

Developing and delivering infrastructure capable of supporting long-term manned operations to the lunar surface has been a primary objective of the Constellation Program in the Exploration Systems Mission Directorate. Several concepts have been developed related to development and deployment lunar exploration vehicles and assets that provide critical functionality such as transportation, habitation, and communication, to name a few. Together, these systems perform complex safety-critical functions, largely dependent on avionics for control and behavior of system functions. These functions are implemented using interchangeable, modular avionics designed for lunar transit and lunar surface deployment. Systems are optimized towards reuse and commonality of form and interface and can be configured via software or component integration for special purpose applications. There are two core concepts in the reference avionics architecture described in this report. The first concept uses distributed, smart systems to manage complexity, simplify integration, and facilitate commonality. The second core concept is to employ extensive commonality between elements and subsystems. These two concepts are used in the context of developing reference designs for many lunar surface exploration vehicles and elements. These concepts are repeated constantly as architectural patterns in a conceptual architectural framework. This report describes the use of these architectural patterns in a reference avionics architecture for Lunar surface systems elements.

Exposure to suicidal behaviors: A common suicide risk factor or a personal negative life event?

PubMed

Harris, Keith M; Bettiol, Silvana

2017-02-01

Numerous suicide risk factors have been proposed but not adequately validated for epidemiology, treatment and prevention efforts. Exposures to suicidal behaviors (ESB), from family and friend suicide attempts and completions, were tested for validity as a suicidal risk factor and also for measurement and construct adequacy. An anonymous online survey yielded 713 participants (aged 18-71), who reported ESB, completed the Suicidal Affect-Behavior-Cognition Scale (SABCS), and comprised a broad spectrum on those variables. Tests of dimensionality and internal consistency showed the four ESB variables (attempts/completions through family/friends) were independent and did not form a common factor or an identifiable ESB latent trait. ESB variables were, however, associated with demographic and psychiatric histories. A battery of tests revealed no meaningful associations between ESB and total suicidality or suicide risk factors (social support, depression, anxiety, stress, satisfaction with life and emotional stability). In addition, in contrast to previous reports, young adults ( n = 200; aged 18-20) showed no increased suicidality due to ESB. Results showed no validity for ESB as a common risk factor for suicidality or other psychopathology, or as a latent trait. ESB showed evidence as a personal negative life event with individual effects and interpretations.

A single wind-mediated mechanism explains high-altitude ‘non-goal oriented’ headings and layering of nocturnally migrating insects

2010-01-01

Studies made with both entomological and meteorological radars over the last 40 years have frequently reported the occurrence of insect layers, and that the individuals forming these layers often show a considerable degree of uniformity in their headings—behaviour known as ‘common orientation’. The environmental cues used by nocturnal migrants to select and maintain common headings, while flying in low illumination levels at great heights above the ground, and the adaptive benefits of this behaviour have long remained a mystery. Here we show how a wind-mediated mechanism accounts for the common orientation patterns of ‘medium-sized’ nocturnal insects. Our theory posits a mechanism by which migrants are able to align themselves with the direction of the flow using a turbulence cue, thus adding their air speed to the wind speed and significantly increasing their migration distance. Our mechanism also predicts that insects flying in the Northern Hemisphere will typically be offset to the right of the mean wind line when the atmosphere is stably stratified, with the Ekman spiral in full effect. We report on the first evidence for such offsets, and show that they have significant implications for the accurate prediction of the flight trajectories of migrating nocturnal insects.

Pulmonary localization is the most common site of tuberculosis (TB)and the most contagious form. Extrapulmonary tuberculosis with the rarest and most unexpected localizations represents a significant proportion of all cases of tuberculosis and remains an important public health problem. We report three unusual TB locations: skin, ear and testis occurred in three immunocompetent patients. In the case of skin and testicular lesions, diagnosis was based on pathological confirmation of granulomas with caseous necrosis. In the third case the diagnosis was made possible by identification of positive Acid-Fast Bacilli smear and positive culture from othic drainage fluid. The outcome at all three patients was good with antituberculous treatment. These unusual localization of tuberculosis also highlight the possibility of extrapulmonary tuberculosis as a differential diagnosis in many common diseases.

Folic acid is involved in two common disorders associated with developmental disabilities. Spina bifida is a malformation that may be associated with mental retardation, learning disabilities, and epilepsy. Its incidence can be reduced by the ingestion of folic acid before, and at the time of, conception. The fragile X syndrome is a genetic disorder which is the most common form of inherited mental retardation. This disorder can be diagnosed by the induction of fragile sites on the X chromosome which is cultured in a medium deficient in folic acid. In several studies, folic acid was reported to alleviate some ofmore » the developmental and behavioral manifestations associated in the fragile X syndrome, while in others, it has no effect. 9 refs.« less

We present the ioChem-BD platform ( www.iochem-bd.org ) as a multiheaded tool aimed to manage large volumes of quantum chemistry results from a diverse group of already common simulation packages. The platform has an extensible structure. The key modules managing the main tasks are to (i) upload of output files from common computational chemistry packages, (ii) extract meaningful data from the results, and (iii) generate output summaries in user-friendly formats. A heavy use of the Chemical Mark-up Language (CML) is made in the intermediate files used by ioChem-BD. From them and using XSL techniques, we manipulate and transform such chemical data sets to fulfill researchers' needs in the form of HTML5 reports, supporting information, and other research media.

Re-constructing our models of cellulose and primary cell wall assembly

Cosgrove, Daniel J.

2014-11-16

The cellulose microfibril has more subtlety than is commonly recognized. Details of its structure may influence how matrix polysaccharides interact with its distinctive hydrophobic and hydrophilic surfaces to form a strong yet extensible structure. We report that recent advances in this field include the first structures of bacterial and plant cellulose synthases and revised estimates of microfibril structure, reduced from 36 to 18 chains. New results also indicate that cellulose interactions with xyloglucan are more limited than commonly believed, whereas pectin-cellulose interactions are more prevalent. Computational results indicate that xyloglucan binds tightest to the hydrophobic surface of cellulose microfibrils. Finally,more » wall extensibility may be controlled at limited regions (“biomechanical hotspots”) where cellulose-cellulose contacts are made, potentially mediated by trace amounts of xyloglucan.« less

This first comprehensive MDSGene review is devoted to the 3 autosomal recessive Parkinson's disease forms: PARK-Parkin, PARK-PINK1, and PARK-DJ1. It followed MDSGene's standardized data extraction protocol and screened a total of 3652 citations and is based on fully curated phenotypic and genotypic data on >1100 patients with recessively inherited PD because of 221 different disease-causing mutations in Parkin, PINK1, or DJ1. All these data are also available in an easily searchable online database (www.mdsgene.org), which also provides descriptive summary statistics on phenotypic and genetic data. Despite the high degree of missingness of phenotypic features and unsystematic reporting of genotype data in the original literature, the present review recapitulates many of the previously described findings including early onset (median age at onset of ∼30 years for carriers of at least 2 mutations in any of the 3 genes) of an overall clinically typical form of PD with excellent treatment response, dystonia and dyskinesia being relatively common and cognitive decline relatively uncommon. However, when comparing actual data with common expert knowledge in previously published reviews, we detected several discrepancies. We conclude that systematic reporting of phenotypes is a pressing need in light of increasingly available molecular genetic testing and the emergence of first gene-specific therapies entering clinical trials. © 2018 International Parkinson and Movement Disorder Society. © 2018 International Parkinson and Movement Disorder Society.

To analyze the clinical course, outcome, contributing factors and factors minimizing the incidents of perioperative myocardial ischemia or infarction (PMI) from Thai AIMS study. The present study was a prospective multicenter study. Data was collected from 51 hospitals in Thailand during a six-month period. The participating anesthesia provider completed the standardized incident report form of the Thai AIMS as soon as they found the PMI incident. Each incident was reviewed by three peer reviewers for clinical courses, contributing factors, outcome and minimizing factors of PMI. From the Thai AIMS incident report, the authors found 25 suspected PMI cases which was 0.9% of the 2,669 incidents reported in the present study. Most of the PMI occurred in elective cases (84%) and orthopedic procedures (56%). The majority of PMI was reported from the patients undergoing general anesthesia (72%). Suspected PMI occurred mostly during operations (56%). New ST-T segment change was detected in 92% of these patients. The most common immediate outcome of PMI was major physiological change (88%). The most common management effect of PMI was unplanned ICU admission (64%); the others were prolonged ventilatory support (12%) and prolonged hospital stay (16%). Four patients (16%) died after the suspected PMI. Most of the events occurred spontaneously and were unpreventable (80%). Patient factors (100%), anesthesia factors (72%), surgical factors (32%) and system factors (8%) were all judged as a precipitating factor for PMI. Human factors were the most common contributing factors which included poor preoperative evaluation, inexperience and improper decision. The three most common factors minimizing the adverse incidents included prior experienced, high awareness and experienced assistance. The recommended corrective strategies were guideline practice, quality assurance activity, improvement of supervision and additional training. Perioperative myocardial ischemia/infarction was infrequent but may be lethal. Patient factors were the most common precipitating cause. The morbidity and mortality could be reduced by high quality preoperative evaluation and preparation, early detection and appropriate treatment. Guideline practice, quality assurance activity, improvement of supervision and additional training were suggested corrective strategies.

Only few studies regarding glomerulonephritis, with relatively small numbers of patients, have so far been published from different centers in Saudi Arabia, and have reported conflicting results regarding the patterns, even in the same city. The possible reasons for these differences include the small number of patients in the different studies, differences in the indications for renal biopsies, referral bias, geographical differences, and, sometimes, the non-availability of the necessary diagnostic facilities in the reporting centers. In order to overcome these problems, a registry for glomerulonephropathy was attempted in Saudi Arabia. Six large referral hospitals from different regions of Saudi Arabia participated in this registry. Biopsy reports and clinical information of 1294 renal biopsies were obtained. There were 782 renal biopsies due to glomerulonephritis (GN) accounting for 77.2% of the total biopsies. Five hundred eighty seven (72.6%) were primary glomerulonephritidis. Focal and segmental glomerulosclerosis (FSGS) (21.3%) and membrano-proliferative glomerulonephritis (MPGN) (20.7%) were the most common types found in the primary glomerulonephritidis. Membranous glomerulonephritis (MGN) was present in only 10.6% of the cases. IgA nephropathy was found in 6.5% of the cases. Of the secondary glomerulo-nephritides, systemic lupus erythematosus (SLE) was the most common indication for biopsy (57.0%) and amyloidosis was found in only 3.2% of the biopsies. In conclusion, FSGS and MPGN were the most common forms of primary glomerulonephritis in adult patients in Saudi Arabia. MGN was not as common as in the western world. SLE was the commonest cause of secondary GN. Amyloidosis was not as common as in other Arab countries. There is a need for more centers from Saudi Arabia to join this national GN registry. Similar registries can be established in different Arab countries, which all would, hopefully, lead to a Pan-Arab GN registry.

Common-Sense Rule Inference

NASA Astrophysics Data System (ADS)

Lombardi, Ilaria; Console, Luca

In the paper we show how rule-based inference can be made more flexible by exploiting semantic information associated with the concepts involved in the rules. We introduce flexible forms of common sense reasoning in which whenever no rule applies to a given situation, the inference engine can fire rules that apply to more general or to similar situations. This can be obtained by defining new forms of match between rules and the facts in the working memory and new forms of conflict resolution. We claim that in this way we can overcome some of the brittleness problems that are common in rule-based systems.

Objective This study assesses three main types of cognition: nonpsychotic thought (odd thinking, unusual perceptual experiences, and non-delusional paranoia), quasi-psychotic thought, and true-psychotic thought in borderline patients followed prospectively for 16 years. It also compares the rates of these disturbed cognitions to those reported by axis II comparison subjects. Method The cognitive experiences of 362 inpatients—290 borderline patients and 72 axis II comparison subjects—were assessed at study entry using the cognitive section of the Revised Diagnostic Interview for Borderlines. Their cognitive experiences were reassessed every two years using the same interview. Results Each of the five main types of thought studied was reported by a significantly higher percentage of borderline patients than axis II comparison subjects over time. Each of these types of thought, except true-psychotic thought, declined significantly over time for those in both groups. Eleven of the 17 more specific forms of thought studied were also reported by a significantly higher percentage of borderline patients over the years of follow-up: magical thinking, overvalued ideas, recurrent illusions, depersonalization, derealization, undue suspiciousness, ideas of reference, other paranoid ideation, quasi-psychotic delusions, quasi-psychotic hallucinations, and true-psychotic hallucinations. Fourteen specific forms of thought were found to decline significantly over time for those in both groups: all forms of thought mentioned above except true-psychotic hallucinations plus marked superstitiousness, sixth sense, telepathy, and clairvoyance. Conclusions Disturbed cognitions are common among borderline patients and distinguishing for the disorder. They also decline substantially over time but remain a problem, particularly those of a nonpsychotic nature. PMID:23558452

To determine the mutations in the CYP21A2 gene in Greek-Cypriots with congenital adrenal hyperplasia (CAH) and attempt a genotype-phenotype correlation. Molecular analysis was performed by multiplex ligation-dependent probe amplification and direct sequencing of PCR products of the CYP21A2 gene in 32 CAH patients. The most frequent genetic defect in the classic salt-wasting and simple virilizing forms was the IVS2-13A/C>G (55%) mutation, followed by Large lesion (20%) and in the non-classical form, the p.V281L (79.5%). Genotypes were categorized in 4 mutation groups (null, A, B and C). All 3 patients in the null group manifested the salt-wasting form and all 6 patients in mutation group A presented with the classical form. One patient in group B had the simple virilizing form and 22 patients in group C exhibited the non-classical form. The spectrum of mutations of the CYP21A2 gene in our population is comparable to the most common reported in similar ethnic groups. The knowledge of the ethnic specificity of the CYP21A2 mutations represents a valuable diagnostic tool for all forms of CAH. Copyright © 2010 S. Karger AG, Basel.

Electronic cigarettes (e-cigarettes) were the most commonly used tobacco product among U.S. middle school and high school students in 2016 (1). CDC and the Food and Drug Administration (FDA) analyzed data from the 2016 National Youth Tobacco Survey (NYTS) to assess self-reported reasons for e-cigarette use among U.S. middle school (grades 6-8) and high school (grades 9-12) student e-cigarette users. Among students who reported ever using e-cigarettes in 2016, the most commonly selected reasons for use were 1) use by "friend or family member" (39.0%); 2) availability of "flavors such as mint, candy, fruit, or chocolate" (31.0%); and 3) the belief that "they are less harmful than other forms of tobacco such as cigarettes" (17.1%). The least commonly selected reasons were 1) "they are easier to get than other tobacco products, such as cigarettes" (4.8%); 2) "they cost less than other tobacco products such as cigarettes" (3.2%); and 3) "famous people on TV or in movies use them" (1.5%). Availability of flavors as a reason for use was more commonly selected by high school users (32.3%) than by middle school users (26.8%). Efforts to prevent middle school and high school students from initiating the use of any tobacco product, including e-cigarettes, are important to reduce tobacco product use among U.S. youths (2).

Aflagellar epimastigote forms are found in axenic culture of Trypanosoma caninum.

2014-09-01

Representatives of the genus Trypanosoma have been traditionally found in epimastigote, espheromastigote and trypomastigote flagellated forms in axenic cultures. Trypanosoma caninum is a trypanosomatid that has recently been reported infecting dogs in endemic areas of canine leishmaniasis in Brazil. It presents specific biological characteristics and it is found exclusively on healthy skin. Here, we describe the evolutive forms of this parasite showing not only the forms commonly found in culture, but also epimastigote forms with no free flagellum. The study was conducted using scanning and transmission electron microscopy and, we demonstrate that typical flagellated epimastigotes originate from forms without flagellum, although the latter may remain without differentiation in the culture. Two hypotheses are considered and discussed in this paper: (i) the aflagellated epimastigotes are a typical developmental forms of T. caninum and (ii) the emergence of these aflagellated forms could be resultant from a disturbed process during cell division caused by interfering specific proteins, which leads to inability to form and regulate the flagellum length. In any case, considering that T. caninum is a parasite that is still little studied, the information brought by our study adds data which may be useful to clarify aspects on the cell cycle of this intriguing parasite that has been found in different regions of Brazil.

Northstone, K.

2007-01-01

Objective To present data on the parentally-reported use of all types of medicinal products in children from 0 to 7.5 years, in a large cohort in south-west England. Methods Participants in the population-based Avon Longitudinal Study of Parents and Children (ALSPAC) have been sent self-completion postal questionnaires since they were enrolled during pregnancy. The use of medicinal products has been obtained from questionnaires sent out when the study children were 4 weeks, 54, 78 and 91 months old. Results The data included prescription, over-the-counter and complementary and alternative medicines. Around three-quarters of study children were exposed to some form of medicinal product before 8 weeks of age. Dermatological preparations were the most commonly used products in young babies. Activated dimeticone, for treatment of colic and flatulence, was given to 16% of babies and gripe water was used by 13%. Other commonly reported products included oral and topical antifungals and ophthalmic antibiotics. Several OTC products, not licensed for use in this age group, were reported. At each of the older ages surveyed, over 95% of children had used some form of medicinal product within the previous 12–18 months. Use of several product categories was higher at 54 months than at 78 or 91 months, such as topical steroids, analgesics (mostly paracetamol) and systemic antibiotics (mainly amoxicillin). Conversely, use of other categories, such as asthma medication, throat preparations (sprays and lozenges) and anti-inflammatory products, increased with increasing age. Conclusion Parentally-reported use of medicinal products in the ALSPAC study children appears to be consistent with data from other sources. The use of medicinal products by young children is high and does not always conform to the product labelling. PMID:17200835

Contemporary management of dupuytren contracture.

PubMed

Rizzo, Marco; Stern, Peter J; Benhaim, Prosper; Hurst, Lawrence C

2014-01-01

Dupuytren contracture is a condition that affects the palmar fascia. It most commonly affects men of northern European ancestry and initially presents at middle age. The diseased fascia may form cords that extend into the digits, resulting in limited motion and function. Treatment is aimed at either releasing or removing the diseased cord so that the finger can extend fully. Common interventions include surgery, needle aponeurotomy, and collagenase injection. Surgery remains the gold standard in treatment and most commonly includes a limited fasciectomy. Although often successful, surgery carries inherent risks and may involve a lengthy recovery with extensive therapy. Needle aponeurotomy and collagenase injections are office-based alternatives that aim to weaken the cord and release the contracture. Needle aponeurotomy involves repeated needling along the cord in intervals and collagenase injections to dissolve a portion of the cord. Despite being less invasive, problems such as nerve and/or tendon injury, skin tears, and autoimmune reactions have been reported. Regardless of treatment, recurrence remains a concern.

Evaluation of control parameters for Spray-In-Air (SIA) aqueous cleaning for shuttle RSRM hardware

Davis, S. J.; Deweese, C. D.

1995-01-01

HD-2 grease is deliberately applied to Shuttle Redesigned Solid Rocket Motor (RSRM) D6AC steel hardware parts as a temporary protective coating for storage and shipping. This HD-2 grease is the most common form of surface contamination on RSRM hardware and must be removed prior to subsequent surface treatment. Failure to achieve an acceptable level of cleanliness (HD-2 calcium grease removal) is a common cause of defect incidence. Common failures from ineffective cleaning include poor adhesion of surface coatings, reduced bond performance of structural adhesives, and failure to pass cleanliness inspection standards. The RSRM hardware is currently cleaned and refurbished using methyl chloroform (1,1,1-trichloroethane). This chlorinated solvent is mandated for elimination due to its ozone depleting characteristics. This report describes an experimental study of an aqueous cleaning system (which uses Brulin 815 GD) as a replacement for methyl chloroform. Evaluation of process control parameters for this cleaner are discussed as well as cleaning mechanisms for a spray-in-air process.

Injuries and allegations of oral rape: A retrospective review of patients presenting to a London sexual assault referral centre.

Brew-Graves, Emmeline; Morgan, Louise

2015-08-01

A retrospective review was carried out of patients seen at the Haven sexual assault referral centre in South East London between January 2009 and September 2010 to determine the frequency and nature of oral injuries found in people reporting oral rape. Ninety five eligible patients were identified and relevant information was extracted from standardised Haven forms completed during forensic medical examination. The main outcome measures were prevalence, type and location of oral injury. Eighteen (19%) were found to have sustained an oral injury. The most common injury was abrasions, followed by bruising and petechiae. The lips were the most common site of injury followed by the soft palate and the inside of the cheeks. It was concluded that injuries in the mouth were not common after an allegation of oral rape. Injuries were minor and did not require treatment.

2013-06-19

The common cold is one of the most common illnesses in humans and constitutes an economic burden both in terms of productivity and expenditure for treatment. There is no proven cure for the common cold and symptomatic relief is the mainstay of treatment. The use of intranasal ipratropium bromide (IB) has been addressed in several studies and might prove an effective treatment for the common cold. To determine the effect of IB versus placebo or no treatment on severity of rhinorrhoea and nasal congestion in children and adults with the common cold. Subjective overall improvement was another primary outcome and side effects (for example, dry mucous membranes, epistaxis and systemic anticholinergic effects) were reported as a secondary outcome. In this updated review we searched CENTRAL 2013, Issue 3, MEDLINE (1950 to March week 4, 2013), MEDLINE in-process and other non-indexed citations (8 April 2013), EMBASE (1974 to April 2013), AMED (1985 to April 2013), Biosis (1974 to February 2011) and LILACS (1985 to April 2013). Randomised controlled trials (RCTs) comparing IB to placebo or no treatment in children and adults with the common cold. Two review authors independently extracted data and assessed trial quality. We used a standardised form to extract relevant data and we contacted trial authors for additional information. Seven trials with a total of 2144 participants were included. Four studies (1959 participants) addressed subjective change in severity of rhinorrhoea. All studies were consistent in reporting statistically significant changes in favour of IB. Nasal congestion was reported in four studies and was found to have no significant change between the two groups. Two studies found a positive response in the IB group for the global assessment of overall improvement. Side effects were more frequent in the IB group, odds ratio (OR) 2.09 (95% confidence interval (CI) 1.40 to 3.11). Commonly encountered side effects included nasal dryness, blood tinged mucus and epistaxis. The overall risk of bias in the included studies was moderate. For people with the common cold, the existing evidence, which has some limitations, suggests that IB is likely to be effective in ameliorating rhinorrhoea. IB had no effect on nasal congestion and its use was associated with more side effects compared to placebo or no treatment although these appeared to be well tolerated and self limiting. There is a need for larger, high-quality trials to determine the effectiveness of IB in relieving common cold symptoms.

To register and analyze data from all crew injuries reported to the medical center of a cruise ship with a median crew of 630 during a three-year period and to determine high risk areas, equipment and behavior. All crew injuries reported to the medical center aboard were registered on a standardized form at first visit. An injury was classified at follow-up as 'lost time accident' (LTA) if it caused the victim to be off work for more than one day and/or to be signed off for medical attention (medical sign-off). During 3 years, 361 injuries (23% women) were reported aboard. Thirty percent were LTA. The marine department accounted for 14% (deck 5%; engine 9%), the hotel'department for 79% and contractors for 7% of the reports. Filipinos comprised half the crew, reported 35% of the accidents, and their rate of serious injuries were lower than non-Filipino crew (p<0.01). Hotel crew had a higher rate of LTA occurring during work than marine crew (p<0.05). The dancers' rate of serious injuries was higher than other hotel crew (p<0.05) and marine crew (p<0.01). The upper extremity was the most frequently injured body part (51%), open wounds the most common injury type (37%), and galleys the most common accident location (30%). Less than one in ten reported injuries caused medical sign-off. Well-equipped, competent medical staff aboard can after crew injury effectively reduce time off work, as well as number of referrals to medical specialists ashore, helicopter evacuations and ship diversions, and medical sign-off.

Charcot-Marie-Tooth (CMT) disease, a hereditary motor and sensory neuropathy that comprises a complex group of more than 50 diseases, is the most common inherited neuropathy. CMT is generally divided into demyelinating forms, axonal forms and intermediate forms. CMT is also characterized by a wide genetic heterogeneity with 29 genes and more than 30 loci involved. The most common pattern of inheritance is autosomal dominant (AD), although autosomal recessive (AR) forms are more frequent in Mediterranean countries. In this chapter we give an overview of the associated genes, mechanisms and epidemiology of AR-CMT forms and their associated phenotypes.

Branchial pouch-derived anomalies may arise from remnants of the first, second, or third/fourth branchial arches. Branchial pouch-related structures are found within the thyroid gland in the form of solid cell rests, epithelial lined cyst with or without an associated lymphoid component, thymic and/or parathyroid tissue, and less commonly in the form of heterotopic cartilage. We present a rare case of left solid thyroid swelling nearby two cervical nodules in a seven-year-old female with a clinical diagnosis suggestive of malignant thyroid tumor with metastasis to the cervical lymph nodes. Histopathological examination revealed that it was compatible with third/fourth branchial pouch-derived anomaly composed of mature cartilage and thymic and parathyroid tissues for clinical and radiological correlations.

Retinitis pigmentosa is a term commonly given to a group of inherited and progressive disorders which affect the photoreceptors of the retina. As part of an ongoing research programme throughout Spain, clinical, epidemiological, and genetic studies have been carried out on these diseases. Here, we report the relative frequencies of the different genetic types in 503 non-syndromic and 89 syndromic RP families of Spanish origin. The most frequent syndromic RP forms were Usher syndrome type 1 (20/89 families = 30%) and Usher syndrome type 2 (44 families = 49%). Among non-syndromic RP forms, 12% were autosomal dominant, 39% autosomal recessive and 4% X-linked. Forty-one percent were isolated or simplex cases and in 4% the genetic type could not be established.

Unhealthy weight loss practices are common among female college students. It is unknown if these practices are also most common among women in the subset of overweight or obese college students or if these practices are related to depression. We examined the relationship between gender, depression, and unhealthy weight loss practices among overweight or obese college students. Students (body mass index between 25.0 and 34.9 kg/m(2)) from three Southern California universities (M(age) = 22 years, SD = 4; 70% women) were recruited from May 2011 to May 2012 for participation in a weight loss clinical trial (N = 404). Logistic regressions were performed with baseline data to assess the cross-sectional relationship between self-reported unhealthy weight loss practices and gender and depression as measured by the Center for Epidemiologic Studies Depression short form. Twenty-nine percent of participants reported engaging in at least one unhealthy weight loss behavior (e.g., fasting, purging) over the last 30 days, with no differences by gender. Self-report of at least one unhealthy weight loss behavior was associated with report of symptoms of depression (e(B) = 1.14 [confidence interval, CI: 1.08-1.20]), adjusting for potential confounders. Interactions between gender and depression were not significant (e(B) = 1.04 [CI: 0.93-1.16]). Among an overweight or obese sample of college students, unhealthy weight loss practices were equally common in both genders, and students with depressive symptomatology were at greatest risk. Obesity interventions targeting overweight or obese college students should educate both men and women about the dangers of unhealthy weight loss practices. In addition, screening for depression can help identify students who would benefit from additional supportive and coping strategies and resources. Copyright © 2014 Elsevier Ltd. All rights reserved.

Studies published from centers across India have reported different and contradicting patterns of glomerular disease. In this retrospective study, we report our experience from a Tertiary Care Center in Northwest India. A total of 702 renal biopsies performed between 2008 and 2013 were reviewed of which 80 were excluded from the study because of having insufficient records or if the biopsies were taken from an allograft. The study included 411 males (66.1 %) and 211 females (33.9%) with an age range of 12-70 years (mean 30.34 ± 7.04 years). Majority of the biopsies (93.9%) showed some form of glomerulonephritis (GN), either primary (79.4%) or secondary glomerular disease (SGD) (14.5%). Minimal change disease (MCD) was the most common type of primary GN (26.5% of primary GN), followed by membranous nephropathy (MN; 18.8%) and focal and segmental glomerulosclerosis (FSGS; 13.2%). Lupus nephritis (LN) was the most frequent SGD (52.2% of secondary GN). Amyloidosis was found in 41.1% and diabetic glomerulosclerosis in 4.4%. LN was also the second most common diagnosis in females after MCD, seen in 19.4% of females. MCD followed by membranoproliferative GN and diffuse proliferative GN were the most common entities in individuals <20 years of age. In the 20-39 years age group, MN was the most common pathology seen. MN was again the most common pathology seen in patients aged above 40 years followed by amyloidosis and FSGS. In this study, MCD was the most common primary GN observed overall from this part of India. MN was the most common GN in individuals above 20 years of age presenting with the nephrotic syndrome. The geographical and regional differences in the pattern of GNs point to the necessity of having a central biopsy registry.

Atomic spectral-product representations of molecular electronic structure: metric matrices and atomic-product composition of molecular eigenfunctions.

Recent progress is reported in development of ab initio computational methods for the electronic structures of molecules employing the many-electron eigenstates of constituent atoms in spectral-product forms. The approach provides a universal atomic-product description of the electronic structure of matter as an alternative to more commonly employed valence-bond- or molecular-orbital-based representations. The Hamiltonian matrix in this representation is seen to comprise a sum over atomic energies and a pairwise sum over Coulombic interaction terms that depend only on the separations of the individual atomic pairs. Overall electron antisymmetry can be enforced by unitary transformation when appropriate, rather than as a possibly encumbering or unnecessary global constraint. The matrix representative of the antisymmetrizer in the spectral-product basis, which is equivalent to the metric matrix of the corresponding explicitly antisymmetric basis, provides the required transformation to antisymmetric or linearly independent states after Hamiltonian evaluation. Particular attention is focused in the present report on properties of the metric matrix and on the atomic-product compositions of molecular eigenstates as described in the spectral-product representations. Illustrative calculations are reported for simple but prototypically important diatomic (H(2), CH) and triatomic (H(3), CH(2)) molecules employing algorithms and computer codes devised recently for this purpose. This particular implementation of the approach combines Slater-orbital-based one- and two-electron integral evaluations, valence-bond constructions of standard tableau functions and matrices, and transformations to atomic eigenstate-product representations. The calculated metric matrices and corresponding potential energy surfaces obtained in this way elucidate a number of aspects of the spectral-product development, including the nature of closure in the representation, the general redundancy or linear dependence of its explicitly antisymmetrized form, the convergence of the apparently disparate atomic-product and explicitly antisymmetrized atomic-product forms to a common invariant subspace, and the nature of a chemical bonding descriptor provided by the atomic-product compositions of molecular eigenstates. Concluding remarks indicate additional studies in progress and the prognosis for performing atomic spectral-product calculations more generally and efficiently.

Pain management in patients with Parkinson's disease: challenges and solutions.

PubMed

Skogar, Orjan; Lokk, Johan

2016-01-01

This review focuses on the diagnosis and management of Parkinson-related pain which is one of the more frequently reported nonmotor symptoms in Parkinson's disease (PD), which is the second most common neurodegenerative disease after Alzheimer's disease. Pain is ranked high by patients as a troublesome symptom in all stages of the disease. In early-stage PD, pain is rated as the most bothersome symptom. Knowledge of the correct diagnosis of pain origin and possible methods of treatments for pain relief in PD is of great importance. The symptoms have a great negative impact on health-related quality of life. Separating PD-related pain from pain of other origins is an important challenge and can be characterized as "many syndromes under the same umbrella". Among the different forms of PD-related pain, musculoskeletal pain is the most common form, accounting for 40%-90% of reported pain in PD patients. Augmentation by pathophysiological pathways other than those secondary to rigidity, tremor, or any of the other motor manifestations of the disease seems most probable. In PD, the basal ganglia process somatosensory information differently, and increased subjective pain sensitivity with lower electrical and heat-pain thresholds has been reported in PD patients. The mechanism is assumed to be diminished activity of the descending inhibitory control system of the basal ganglia. PD pain, like many of the nonmotor symptoms, remains underdiagnosed and, thus, poorly managed. A systematic collection of patient descriptions of type, quality, and duration of pain is, therefore, of utmost importance. Recent studies have validated new and more specific and dedicated pain scales for PD-related symptoms. Symptomatic treatments based on clinical pain classification include not only pharmacological but also nonpharmacological methods and, to some degree, invasive approaches. In the clinic, pharmacological and nonpharmacological interventions can be effective to varying degrees - as single therapies or in combination - and should be employed, because no therapeutic strategies have been validated to date for managing PD pain. Multimodal approaches should always be considered, dopamine replacement therapies should be adjusted, and analgesics and/or antidepressants should be considered, including the use of different forms of complementary therapies.

Glucose-6-phosphate dehydrogenase deficiency (G6PD deficiency) is the most common red blood cell (RBC) enzyme disorder. The decrease as well as the absence of the enzyme increase RBC vulnerability to oxidative stress caused by exposure to certain medications or intake of fava beans. Among the most common clinical manifestations of this condition, acute hemolysis, chronic hemolysis, neonatal hyperbilirubinemia, and an asymptomatic form are observed. To analyze the case of a child who presented hemolytic crisis due to favism. A 2 year and 7 month old boy with a history of hyperbilirubinemia during the newborn period with no apparent cause, no family history of hemolytic anemia or parental consanguinity. He presented a prolonged neonatal jaundice and severe anemia requiring RBC transfusion. An intake of fava beans 48 h prior to onset of symptoms was reported. G6PD qualitative determination was compatible with this enzyme deficiency. G6PD deficiency can be highly variable in its clinical presentation, so it is necessary to keep it in mind during the diagnosis of hemolytic anemia at any age.

A national population-based assessment of 2007–2008 election-related violence in Kenya

Background Following the contested national elections in 2007, violence occurred throughout Kenya. The objective of this study was to assess the prevalence, characteristics, and health consequences of the 2007–2008 election-related violence. Methods A cross-sectional, national, population-based cluster survey of 956 Kenyan adults aged ≥ 18 years was conducted in Kenya in September 2011 utilizing a two-stage 90 x 10 cluster sample design and structured interviews and questionnaires. Prevalence of all forms of violence surrounding the 2007 election period, symptoms of major depressive disorder (MDD) and posttraumatic stress disorder (PTSD), and morbidity related to sexual and physical violence were assessed. Results Of 956 households surveyed, 916 households participated (response rate 95.8%). Compared to pre-election, election-related sexual violence incidents/1000 persons/year increased over 60-fold (39.1-2370.1; p < .001) with a concurrent 37-fold increase in opportunistic sexual violence (5.2-183.1; p < .001). Physical and other human rights violations increased 80-fold (25.0-1987.1; p < .001) compared to pre-election. Overall, 50% of households reported at least one physical or sexual violation. Households reporting violence were more likely to report violence among female household members (66.6% vs. 58.1%; p = .04) or among the Luhya ethnic group (17.0% vs. 13.8%; p = 0.03). The most common perpetrators of election-related sexual violence were reported to be affiliated with government or political groups (1670.5 incidents/1000 persons per year); the Kalenjin ethnic group for physical violations (54.6%). Over thirty percent of respondents met MDD and PTSD symptom criteria; however, symptoms of MDD (females, 63.3%; males, 36.7%; p = .01) and suicidal ideation (females, 68.5%; males, 31.5%; p = .04) were more common among females. Substance abuse was more common among males (males, 71.2%; females, 28.8%; p < .001). Conclusion On a national level in Kenya, politically-motivated and opportunistic sexual and physical violations were commonly reported among sampled adults with associated health and mental health outcomes.

Deception for drugs: self-reported "doctor shopping" among young adults.

Pharmaceutical abuse is a burgeoning problem, and various forms of drug diversion are becoming more common. At present, little is known about those who attempt to deceive physicians to receive medications, and even less is known about those who successfully avoid detection and abuse-related repercussions. The goal of this study is to assess the prevalence of attempted physician deception in a general population, explore common motives, and evaluate risk factors associated with the behavior. A stratified random sampling technique was used to obtain a locally representative sample of 2349 young adults. The sample was 48.4% male, 68.9% white, 24.4% black, and 2.8% Hispanic. Selected individuals were surveyed using a self-report instrument (80.4% response rate). Of the respondents, 93 (4.0%) self-reported having attempted to deceive a physician to obtain a pharmaceutical. Most of these indicated that they were at least partially motivated by their own abuse. Approximately half reported that selling a portion of the prescription was a motivating factor. Alcohol use, marijuana use, and pharmaceutical misuse each were risk factors associated with attempted deception. Although no traits were definitively linked to the behavior, attempted deception was more commonly reported by men, Hispanics, self-identified lesbian/gay/bisexual/transgender individuals, and those at the lowest and highest extremes of the income spectrum. Logistic regression models of rare events indicated that past substance use along with sexual orientation and family income were related to attempted deception when controlling for other factors. Results suggest that attempted physician deception may be more common than previously believed. Practicing physicians should attempt to use risk factor information presented within this study, albeit very cautiously. This study identifies general characteristics of young people who might divert medications but notes that only a small minority of any patient group will do so. Awareness should not equal bias in the treatment of these patients; instead, it should reinforce the need for careful clinical interviewing and the utilization of prescription drug monitoring programs and local law enforcement databases. © Copyright 2014 by the American Board of Family Medicine.

Familial polythelia over three generations with polymastia in the youngest girl.

Supernumerary nipples or polythelia are developmental abnormalities located along the embryonic mammary lines. It is the most common form of accessory breast tissue malformation and usually occurs sporadically but familial aggregation has been reported. Polythelia has been reported in association with congenital malformations, in particular with renal anomalies. Polymastia in female patients has been reported to manifest usually during pregnancy or lactation. We report on a pedigree with six cases of polythelia over three generations and one case of polythelia and polymastia in the youngest member of this family. The girl (11 years old ) had in addition to six supernumerary nipples, an accessory breast gland located under the normal left breast. No other congenital malformations could be detected. This girl will remain under follow-up until the end of puberty when the accessory breast gland will be removed. Manifestation of polymastia during puberty rarely has been reported. Polymastia may appear with familial polythelia even without renal anomalies.

Vasculopathy is rarely reported in neurofibromatosis type 1, but when it occurs it primarily involves the aorta and its main branches. Among vasculopathies, aneurysmal dilatation is the most common form. Although several case reports concerning aneurysms or pseudoaneurysms of visceral arteries in neurofibromatosis type 1 patients have been reported, there are no reports describing gastroduodenal artery aneurysms associated with neurofibromatosis type 1. We experienced a case of life-threatening duodenal ulcer bleeding from a ruptured gastroduodenal artery aneurysm associated with neurofibromatosis type 1. We treated our patient by transarterial embolization after initial endoscopic hemostasis. To our knowledge, this is the first reported case of its type. High levels of suspicion and prompt diagnosis are required to select appropriate treatment options for patients with neurofibromatosis type 1 experiencing upper gastrointestinal bleeding. Embolization of the involved arteries should be considered an essential treatment over endoscopic hemostasis alone to achieve complete hemostasis and to prevent rebleeding.

Summary High-risk neuroblastoma remains one of the deadliest childhood cancers. Identification of metabolic pathways that drive or maintain high-risk neuroblastoma may open new avenues of therapeutic interventions. Here we report the isolation and propagation of neuroblastoma sphere-forming cells with self-renewal and differentiation potential from tumors of TH-MYCN mice, an animal model of high-risk neuroblastoma with MYCN amplification. Transcriptional profiling reveals that mouse neuroblastoma sphere-forming cells acquire a metabolic program characterized by transcriptional activation of the cholesterol and serine-glycine synthesis pathways, primarily as a result of increased expression of sterol regulatory element-binding factors and Atf4, respectively. This metabolic reprogramming is recapitulated in high-risk human neuroblastomas and is prognostic for poor clinical outcome. Genetic and pharmacological inhibition of the metabolic program markedly decreases the growth and tumorigenicity of both mouse neuroblastoma sphere-forming cells and human neuroblastoma cell lines. These findings suggest a therapeutic strategy for targeting the metabolic program of high-risk neuroblastoma. PMID:27705805

2018-04-01

Exposure to multiple forms of violence is common amongst adolescents from socioeconomically disadvantaged communities in South Africa. Adolescents' exposure to violence at home, in school and in their communities can lead to detrimental outcomes in education. In particular, adolescents who are more frequently exposed to multiple forms of violence are at risk of school delay. This paper investigates the potential for supportive parenting to protect against adolescents' school delay in this context. With this aim, this paper applies structural equation modelling to a sample of 503 adolescents exposed to multiple forms of violence from 40 socioeconomically disadvantaged communities. Adolescents' self-report data on child abuse in the family, school and community, and adolescents' perceptions of positive parenting, consistent discipline, good monitoring, parental involvement and social support were analyzed. Results showed that perceptions of more positive parenting and consistent discipline moderated the relationship between more frequent exposure to multiple forms of violence and school delay. Our findings suggest that supportive parenting has the potential to protect against school delay for poly-victimized adolescents in South Africa. Copyright © 2017 Elsevier Ltd. All rights reserved.

Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) orders have been in use since the 1990s. The Resuscitation Council UK (RCUK) provides guidance on the content and use of such forms in the UK but there is no national policy. To determine the content of DNACPR forms in the UK, and the geographical distribution of the use of different forms. All acute trusts within the United Kingdom were contacted via a combination of email and telephone, with a request for the current DNACPR form along with information about its development and use. Characteristics of the model RCUK DNACPR form were compared with the non-RCUK DNACPR forms which we received. Free text responses were searched for commonly occurring phrases. 118/161 English NHS Acute Trusts (accounting for 377 hospitals), 3/6 Northern Irish NHS Acute Trusts (accounting for 25 hospitals) and 3/7 Welsh Health Boards (accounting for 73 hospitals) responded. All Scottish hospitals have the same form. All responding trusts had active policies and have a DNACPR form in use. 38.9% of respondent hospitals have adopted the RCUK form with minor amendments. The remainder of the responding hospitals reported independent forms. 66.8% of non-RCUK forms include a transfer plan to ambulance staff and 48.4% of non-RCUK forms are valid in the community. Several independent trusts submitted DNACPR forms with escalation plans. There is wide variation in the forms used for indicating DNACPR decisions. Documentation is rapidly evolving to meet the needs of patients and to respond to new evidence. Copyright © 2014. Published by Elsevier Ireland Ltd.

Unwanted Sexual Experiences in Young Men: Evidence from a Survey of University Students in Chile

2012-01-01

The public health problem of unwanted sexual experiences (USE) in male youths has received little attention. In this study, we examined prevalence of USE, risk factors, contexts, and barriers to disclosure with data from a quantitative survey of students enrolled in General Education courses at a public university in Chile. This study focused on the male sample (N = 466). Approximately 20.4% of participants reported some form of USE since age 14. Forced sex through physical coercion, forced sex through verbal coercion or while intoxicated, attempted forced sex, and less severe forms of USE were reported by 0.2%, 10.1%, 1.4%, and 8.7% of participants, respectively. USE before age 14 was reported by 9.4% of participants and was a significant predictor of USE since age 14 (AOR 6.38, 95% CI 3.22–12.65, p < .01). The perpetrator of USE since age 14 was most commonly identified as a date/partner or friend/acquaintance; other findings on contexts and barriers to disclosure were also generally consistent with previous results in the literature. In addition, we found substantial co-occurrence of USE since age 14 with two other forms of coercion: physical dating violence victimization and coerced condom non-use. The study findings indicate a need for further attention to these public health problems and have implications for the development of violence and HIV/STI prevention programs for adolescent boys and young adult men in Chile and elsewhere.

Streptococcus suis is a common infection of pigs. Human infection is often related to accidental inoculation through skin injuries during occupational exposure to pigs and pork. The disease may present as meningitis, bacteremia, and less commonly endocarditis, arthritis, or bronchopneumonia. Case report and review of the literature. We report a case of bacteremia and severe sepsis caused by S. suis serotype 2 complicated by septic arthritis in a 56-year-old male with history of a prior contact with unprocessed pork. The causative agent was isolated from blood cultures and aspirated synovial fluid. The patient's condition improved after treatment with penicillin, but he was found subsequently to have an abdominal aortic aneurysm, confirmed by computed tomography (CT) scan. The mycotic aneurysm was successfully repaired using an in situ graft reconstruction. Tissue samples analyzed using polymerase chain reaction identified S. suis serotype 2 as the causative organism. After completion of two weeks of parenteral antibiotics, an oral form of ciprofloxacin (0.25 g twice a day) was continued for one month. The patient was discharged from our institution after uncomplicated recovery. Clinical review, a CT scan, and inflammatory markers nine months after surgery revealed no evidence of infection. This is the first report of mycotic aneurysm caused by S. suis, which may be an etiologic agent of mycotic aneurysms, especially when complicated by bacteremia in adults with a recent history of contact with pigs or unprocessed pork.

While mucoceles of the oral mucosa are relatively common, multiple mucous retention cysts have not previously been reported. In this article two such cases, in which numerous minor salivary gland ducts had dilated to the point of cyst formation, are described. The number of individual cysts exceeded 100 in each case. Since it is clear that these cysts formed as a result of dilatation of salivary ducts, it would seem that either the ducts were blocked by altered secretion or there was an acquired or congenital weakness in their structure.

Poppy seed tea (PST) has a long history of use for its medicinal (analgesic, anti-diarrhoeal, anxiolytic) effects. It is also commonly used as a recreational drug in its oral form throughout the world, but reports of intravenous use are very rare. We present two cases of intravenously injected PST with dramatic effects in order to create awareness among health professionals of this method of drug use and its potential complications, as well as to help clinicians dealing with opiate-dependent patients to warn them of the risk.

Congenitally corrected transposition of the great arteries is a rare form of CHD. Situs inversus is a much less common variant of a congenitally corrected transposition of the great arteries. In rare cases, transposition events may be accompanied by various cardiac anomalies. However, situs inversus patients with congenitally corrected transposition, single coronary artery anomaly, and atrioventricular block together have not been reported previously. This combination of abnormalities is presented as a first in the literature.

Immunomodulatory drugs (IMiDs) currently used in the treatment of multiple myeloma, are thalidomide, lenalidomide and pomalidomide. One of the most common side effects of thalidomide is neurotoxicity, predominantly in the form of peripheral neuropathy. We report 6 cases of significant central neurotoxicity associated with IMiD therapy. Treatment with thalidomide (1 patient), lenalidomide (4 patients), and pomalidomide (1 patient) was associated with various clinical manifestations of central neurotoxicity, including reversible coma, amnesia, expressive aphasia, and dysarthria. Central neurotoxicity should be recognized as an important side effect of IMiD therapy.

Pasteurella multocida is known to form part of the normal flora in the nasopharynx or gastrointestinal tract in many domestic and wild animals. Most human P multocida infections are soft tissue infections caused by dog or cat bites. Less commonly this bacterium is associated with infections affecting other organ systems of man. A case of fatal P multocida meningitis discovered at the necropsy of a 52 year old man is described. P multocida is an unusual causative agent of meningitis which tends to affect those at the extremes of age.

Stuttering is a disturbance in the normal fluency and time patterning of speech. Developmental stuttering (DS), with or without associated psychiatric illness, is the most common form and includes all cases with gradual onset in childhood that are not the result of acquired brain damage. Persistent developmental stuttering (PDS) is DS that has not undergone spontaneous or speech therapy-induced remission. Adults in speech therapy behavioral programs will often show regression and even total relapse if they stop practicing. This case report deals with a patient of PDS who responded significantly to treatment with fluoxetine.

Alzheimer’s disease (AD) is the most common form of dementia, and it generally affects the elderly. It has been suggested that diet is an intensively modifiable lifestyle factor that might reduce the risk of AD. Because epidemiological studies generally report the potential neuronal protective effects of various micronutrients, the aim of this study was to perform a literature review on the major nutrients that are related to AD, including selenium, vitamins C and E, transition metals, vitamin D, B-complex vitamins, and omega-3 fatty acids.

Occipital neuralgia is a common form of headache that is characterized by paroxysmal severe lancinating pain in the occipital nerve distribution. The exact pathophysiology is still not fully understood and occipital neuralgia often develops spontaneously. There are no specific guidelines for evaluation of patients with occipital neuralgia. Cervical spine, spinal cord and posterior neck muscle lesions can induce occipital neuralgia. Brain and spine imaging may be necessary in some cases, according to the nature of the headache or response to treatment. We report a case of cervical myelitis presenting as occipital neuralgia.

Purpose of review Ophthalmologists and rheumatologists frequently miscommunicate in consulting on patients with retinal vasculitis. This report seeks to establish a common understanding of the term, retinal vasculitis, and to review recent papers on this diagnosis. Recent findings 1) The genetic basis of some rare forms of retinal vascular disease have recently been described. Identified genes include CAPN5, TREX1, and TNFAIP3; 2) Behçet’s disease is a systemic illness that is very commonly associated with occlusive retinal vasculitis; 3) retinal imaging including fluorescein angiography and other newer imaging modalities has proven crucial to the identification and characterization of retinal vasculitis and its complications; 4) although monoclonal antibodies to IL-17A or IL-1 beta failed in trials for Behçet’s disease, antibodies to TNF alpha, either infliximab or adalimumab, have demonstrated consistent benefit in managing this disease. Interferon treatment and B cell depletion therapy via rituximab may be beneficial in certain types of retinal vasculitis. Summary Retinal vasculitis is an important entity for rheumatologists to understand. Retinal vasculitis associated with Behçet’s disease responds to monoclonal antibodies that neutralize TNF, but the many other forms of non-infectious retinal vasculitis may require alternate therapeutic management.

Agencies that oversee complex, multi-stakeholder programs need efficient, secure ways to link people and knowledge within and across organizations. The Common Operating Response Environment (CORE), a software suite developed by PNNL researchers does just that. The CORE tool—which is customizable for a multitude of uses—facilitates situational awareness by integrating diverse data streams without the need to reformat them, summarizing that information, and providing users with the information they need to rapidly understand and appropriately respond to situations. It is mobile device-ready, has a straightforward interface for ease of use across organizations and skill sets, and is incredibly configurable to the needs of each specific user, whether they require data summaries for high-level decision makers or tactical maps, operational data, or weather information for responders in the field. Information can be input into CORE and queried in a variety of ways—using customized forms, reports, visuals, or other organizational templates—according to the needs of each user’s organization, teams, and business processes. CORE data forms, for instance, could be accessed and used in real-time to capture information about vessels being inspected for nuclear material.

Undergraduate psychiatry students' attitudes towards teaching methods at an Irish university.

2016-11-01

At University College Dublin, teaching in psychiatry includes clinical electives, lectures, small-group and problem-based teaching, consistent with international trends. To determine final-year psychiatry students' attitudes towards teaching methods. We distributed questionnaires to all final-year medical students in two classes (2008 and 2009), after final psychiatry examination (before results) and all of them participated (n = 111). Students' interest in psychiatry as a career increased during psychiatry teaching. Students rated objective structured clinical examination (OSCE) as the most useful element of teaching and examination. The most common learning style was "reflector"; the least common was "pragmatist". Two thirds believed teaching could be improved (increased patient contact) and 89 % reported that experience of psychiatry changed attitudes towards mental illness (increased understanding). Students' preference for OSCEs may reflect the closeness of OSCE as a form of learning to OSCE as a form of assessment: OSCEs both focus on specific clinical skills and help prepare for examinations. Future research could usefully examine the extent to which these findings are university-specific or instructor-dependent. Information on the consistency of various teaching, examination and modularisation methods would also be useful.

Major Evolutionary Trends in Hydrogen Isotope Fractionation of Vascular Plant Leaf Waxes

Gao, Li; Edwards, Erika J.; Zeng, Yongbo; Huang, Yongsong

2014-01-01

Hydrogen isotopic ratios of terrestrial plant leaf waxes (δD) have been widely used for paleoclimate reconstructions. However, underlying controls for the observed large variations in leaf wax δD values in different terrestrial vascular plants are still poorly understood, hampering quantitative paleoclimate interpretation. Here we report plant leaf wax and source water δD values from 102 plant species grown in a common environment (New York Botanic Garden), chosen to represent all the major lineages of terrestrial vascular plants and multiple origins of common plant growth forms. We found that leaf wax hydrogen isotope fractionation relative to plant source water is best explained by membership in particular lineages, rather than by growth forms as previously suggested. Monocots, and in particular one clade of grasses, display consistently greater hydrogen isotopic fractionation than all other vascular plants, whereas lycopods, representing the earlier-diverging vascular plant lineage, display the smallest fractionation. Data from greenhouse experiments and field samples suggest that the changing leaf wax hydrogen isotopic fractionation in different terrestrial vascular plants may be related to different strategies in allocating photosynthetic substrates for metabolic and biosynthetic functions, and potential leaf water isotopic differences.

Acinar cell carcinoma (ACC) of the pancreas is relatively rare, accounting for only approximately 1% of all exocrine pancreatic tumors. A 69-year-old man was found to have a mass lesion measuring approximately 4 cm in diameter in the pancreatic head on ultrasound, abdominal dynamic CT, and percutaneous transhepatic cholangiography. Magnetic resonance cholangiopancreatography showed defect of the lower common bile duct (CBD) due to obstruction by the tumor cast. Histopathologically, the pancreatic head tumor invaded the main pancreatic duct (MPD) and CBD with extension into the CBD in a form of tumor cast. The tumor cells consisted of a solid proliferation with abundant eosinophilic cytoplasm and round nuclei in an acinar and trabecular fashion. A 55-year-old man with upper abdominal pain and nausea, had a cystic lesion approximately 3 cm in size in the pancreatic tail on CT. Histopathologically, the tumor was encapsulated by fibrous capsule and had extensive central necrosis with solid areas in the tumor periphery, and invaded with extension into the MPD in a form of tumor cast. The tumor cells resembled acinar cells in solid growths. Two resected cases of ACC with unusual tumor extension into the CBD and the MPD, respectively, are reported.

The frequent occurrence of aggression within committed romantic relationships is well documented. However, little is known about experiences of interpersonal aggression within casual sexual relationships and experiences. This study aimed to describe the occurrence of emotional, physical, and sexual aggression victimization within committed romantic relationships, casual dating relationships, friends-with-benefit relationships, booty-calls, and one-night stands. College students (N = 172) provided data regarding the lifetime occurrence of emotional, physical, and sexual aggression across different forms of casual sexual relationships and experiences (friends-with-benefits, booty-call, casual dating, one-night stands, committed relationships). Emotional, physical, and sexual subtypes of aggression were reported across all casual sexual relationships and experiences. While a higher percentage of individuals who had been involved in committed relationships reported experiencing at least one form of aggression (approximately 69%), prevalence of at least one form of aggression ranged from approximately 31% to 36% for the various casual sexual relationships/experiences. Across relationships/experiences, emotional and sexual aggression were more common than physical aggression. The findings from this study indicate that emotional, physical, and sexual aggression occur across types of relationships and experiences. Thus, the current study underscores the importance of considering casual dating, friends-with-benefits, booty-calls, and one-night stands when assessing interpersonal aggression.

This study examined differences in offending behavior and psychosocial problems between juvenile offenders who have been sexually abused (n=231), physically abused (n=1,568), neglected (n=1,555), exposed to multiple forms of maltreatment (n=1,767), and non-victims (n=8,492). In addition, the moderating effect of gender in the association between type of maltreatment and offending behavior/psychosocial problems was examined. Results showed that violent offenses were more common in victims of physical abuse and victims of multiple forms of abuse than in non-victims, both in boys and girls. In boys, sexual offenses were far more common in victims of sexual abuse than in victims of other or multiple forms of maltreatment or in non-victims. In girls, no group differences were found in sexual offending behavior. For both boys and girls, externalizing problems were relatively common in victims of physical abuse and neglect whereas internalizing problems were relatively common in victims of sexual abuse. In victims of multiple forms of maltreatment, both internalizing and externalizing problems were relatively common. Implications for clinical practice are discussed. Copyright © 2015 Elsevier Ltd.

A typical muscle variation of latissimus dorsi — the axillary arch is represented by the muscular or fibromuscular slip detached from the anteroinferior border of the musculus latissimus dorsi passing over the axilla under the axillary fascia crossing the medial side of the brachial plexus to continue as a septum intermusculare mediale brachii distally to the medial epicondyle of humerus. The full extent of the muscle is rarely present. Slips of muscle extend from the latissimus dorsi at the inferior angle of scapula to insert into pectoralis major (Langer), coracobrachilis, biceps or coracoid process forming what is described as a common variant - the muscular axillary arch. We report three cases of variants of latissimus dorsi, one of which has not been reported in the literature before. PMID:25593441

Ectodermal dysplasia is a rare disease which affects at least two ectodermal-derived structures such as hair, nails, skin, sweat glands and teeth. Approximately 200 different conditions have been classified as an ectodermal dysplasia and X-linked hypohidrotic ectodermal dysplasia (XHED) represents the commonest form. Clinically, XHED is characterized by hypotrichosis, hypohidrosis and hypodontia. A variety of ocular manifestations have been reported in XHED, the most common being dryness of eyes due to tear deficiency and instability of the film secondary to the absence of meibomian gland function. Here we report a child with the distinctive clinical features of XHED confirmed with molecular diagnosis who presented with infantile bilateral glaucoma, in addition to the classical ocular involvement in XHED.

Switch from sexual to parthenogenetic reproduction in a zebra shark

2017-01-01

Parthenogenesis is a natural form of asexual reproduction in which embryos develop in the absence of fertilisation. Most commonly found in plants and invertebrate organisms, an increasing number of vertebrate species have recently been reported employing this reproductive strategy. Here we use DNA genotyping to report the first demonstration of an intra-individual switch from sexual to parthenogenetic reproduction in a shark species, the zebra shark Stegostoma fasciatum. A co-housed, sexually produced daughter zebra shark also commenced parthenogenetic reproduction at the onset of maturity without any prior mating. The demonstration of parthenogenesis in these two conspecific individuals with different sexual histories provides further support that elasmobranch fishes may flexibly adapt their reproductive strategy to environmental circumstances.

Sub-epidermal calcified nodule (SCN) is an uncommon form of idiopathic calcinosis. It usually occurs in children, particularly in the head and neck region, presenting as a solitary, painless, yellow-white nodule with papillomatous features. These lesions occur twice as common in males compared with females. The pathogenesis is uncertain, but the clinical and histological features of this lesion are distinctive. We report a case of 22-year-old man with multiple nodules bilaterally located on the dorsum of hands simulating eruptive xanthoma. Histopathological examination of one of the excised lesion confirmed the diagnosis showing epidermal and sub-epidermal deposition of calcium. This paper presents a review of the literature and adds a new case of SCN. PMID:24082201

Physical therapists (PTs) frequently provide neuromusculoskeletal treatment for patients who incidentally may have one or more tattoos. Low level light therapy (LLLT) is one of the modalities commonly used by physical therapists to decrease pain and facilitate healing. This case report describes a 22 year old man who was given LLLT to address his complaints of musculoskeletal pain. Blistering of the skin was documented over the LLLT application site, a black tattoo. The blisters, which formed after the LLLT treatment were most likely caused by the inadvertent and unexpected heating of the iron oxides and/or the metal salts in the tattoo's black pigment. PTs should exercise caution when applying LLLT in the presence of dark tattoos. Copyright © 2016 Elsevier Ltd. All rights reserved.

Livestock-Associated Methicillin-Resistant Staphylococcus aureus (LA-MRSA) Isolates of Swine Origin Form Robust Biofilms

PubMed Central

Nicholson, Tracy L.; Shore, Sarah M.; Smith, Tara C.; Fraena, Timothy S.

2013-01-01

Methicillin-resistant Staphylococcus aureus (MRSA) colonization of livestock animals is common and prevalence rates for pigs have been reported to be as high as 49%. Mechanisms contributing to the persistent carriage and high prevalence rates of livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) strains in swine herds and production facilities have not been investigated. One explanation for the high prevalence of MRSA in swine herds is the ability of these organisms to exist as biofilms. In this report, the ability of swine LA-MRSA strains, including ST398, ST9, and ST5, to form biofilms was quantified and compared to several swine and human isolates. The contribution of known biofilm matrix components, polysaccharides, proteins and extracellular DNA (eDNA), was tested in all strains as well. All MRSA swine isolates formed robust biofilms similar to human clinical isolates. The addition of Dispersin B had no inhibitory effect on swine MRSA isolates when added at the initiation of biofilm growth or after pre-established mature biofilms formed. In contrast, the addition of proteinase K inhibited biofilm formation in all strains when added at the initiation of biofilm growth and was able to disperse pre-established mature biofilms. Of the LA-MRSA strains tested, we found ST398 strains to be the most sensitive to both inhibition of biofilm formation and dispersal of pre-formed biofilms by DNaseI. Collectively, these findings provide a critical first step in designing strategies to control or eliminate MRSA in swine herds. PMID:23951352

Development and testing of item response theory-based item banks and short forms for eye, skin and lung problems in sarcoidosis.

Sarcoidosis is a multisystem disease that can negatively impact health-related quality of life (HRQL) across generic (e.g., physical, social and emotional wellbeing) and disease-specific (e.g., pulmonary, ocular, dermatologic) domains. Measurement of HRQL in sarcoidosis has largely relied on generic patient-reported outcome tools, with little disease-specific measures available. The purpose of this paper is to present the development and testing of disease-specific item banks and short forms of lung, skin and eye problems, which are a part of a new patient-reported outcome (PRO) instrument called the sarcoidosis assessment tool. After prioritizing and selecting the most important disease-specific domains, we wrote new items to reflect disease-specific problems by drawing from patient focus group and clinician expert survey data that were used to create our conceptual model of HRQL in sarcoidosis. Item pools underwent cognitive interviews by sarcoidosis patients (n = 13), and minor modifications were made. These items were administered in a multi-site study (n = 300) to obtain item calibrations and create calibrated short forms using item response theory (IRT) approaches. From the available item pools, we created four new item banks and short forms: (1) skin problems, (2) skin stigma, (3) lung problems, and (4) eye Problems. We also created and tested supplemental forms of the most common constitutional symptoms and negative effects of corticosteroids. Several new sarcoidosis-specific PROs were developed and tested using IRT approaches. These new measures can advance more precise and targeted HRQL assessment in sarcoidosis clinical trials and clinical practice.

Local factors with a possible influence on the frequency and histological type of thyroid cancer are examined in the light of cases observed at the Mauriziano Hospital in the last 10 years. The overall number of cases has been increasing and papilliferous forms have been more common than follicular forms. Iodine deficiency and thyrotropin hyper-stimulation encourage onset and account for the higher frequency of thyroid cancer in endemic areas, where, however, follicular forms are more common. Ironising radiation is a direct cause, particularly of papilliferous forms arising after exposure during youth.

The purpose of this study was to assess the physical demands, injuries, and conditioning practices of stock car drivers. Forty stock car drivers from 27 states in the United States participated in the interviews for 43.9 ± 13.9 minutes. The interviews examined background information, the physical demands of racing, injuries associated with racing, and the athletic and fitness background and practices of the subjects. Numerical data were analyzed using Pearson's correlation coefficients. Responses to open-ended questions were analyzed using inductive content analysis. Results revealed significant correlation between track points standings and the length of the resistance training sessions (R = -0.71, p = 0.002) and subject self-assessment of their fitness (R = -0.53, p = 0.045). Results also revealed that "upper-body strength" was identified as the most important physical demand. Extreme fatigue was the most common feeling after a demanding race. Subjects reported that shoulder fatigue was the most common form of muscle soreness experienced after a race. Back and torso injuries were the most common injury, although head injuries most frequently required medical attention. The subjects' biggest fear was fire, followed closely by head and neck injury. The bench press and running were the most commonly performed resistance training and cardiovascular exercises, respectively. Subjects reported that their highest motivation for training was to improve their racing performance. Many subjects had athletic backgrounds with football identified as the sport they had most commonly participated in. This study provides additional detailed information. Results of this study can assist strength and conditioning professionals in the development of strength and conditioning programs for performance enhancement and injury prevention that are specific to the needs of this population of athletes.

A review of the literature was performed using the PubMed and OVID databases searching the keywords asthma, allergy, and CAM to identify studies published between 1980 and 2003 that focused on Echinacea (Echinacea augustifolia, Echinacea pallida, and Echinacea purpurea); garlic (Allium); angelica; chamomile; ephedra; gingko; grape seed extract; licorice root (Glycyrrhiza); St. John's wort (Hypericum); kava kava (Piper); peppermint oil and leaf (Mentha); stinging nettle (Urtica); and ginseng (Panax) published in the English and German literature. Studies included in vitro and in vivo clinical trials and case reports selected according to the expert opinion of the author. Echinacea is one of the most common herbs used to treat symptoms of the "common cold" or upper respiratory tract allergies. Although no common drug interactions have been reported, there is a risk of hepatotoxicity, exacerbation of allergies and asthma, and anaphylactic reactions. Garlic is primarily used for cardiovascular health and relief of cough, colds, and rhinitis. Adverse effects commonly include gastrointestinal disturbances, change in body odor through the sweat and breath, and rarely allergic reactions or hypoglycemia. Other CAM agents, including angelica, German chamomile flower, ephedra, gingko, grape seed extract, licorice root, St. John's wort, kava kava rhizome, peppermint, stinging nettle, and ginseng, are also associated with significant adverse effects. The specialty of allergy and immunology has seen the second largest increase in the popularity of CAM (second only to practitioners who treat lower back pain). Almost all of the CAM interventions have displayed adverse effects, usually in the form of a hypersensitivity reaction. Allergists and clinical immunologists need to become more knowledgeable about CAM so that they can inform patients about the use and possible abuse of these modalities.

The purpose of this study is to describe a system for formally reporting second-opinion interpretations of CT imaging exams accompanying patients transferred emergently to a tertiary care center. Second-opinion interpretations of cross-sectional imaging exams rendered in the emergency department setting over 6 months spanning 22 September 2009 to 22 March 2010 were reviewed and tallied by two radiologists and a research assistant, with a focus on professional fee reimbursement rates. A more in depth review was performed of those exams for which a clinical referral request form was available, detailing such information as the clinical history, content and source of available initial interpretation, and congruity of the initial interpretation with clinical data. Discrepancies between outside and second-opinion interpretations were also assessed. This quality assurance exercise was reviewed by our institutional review board, which waived formal informed consent. Formal second-opinion interpretation was rendered for 370 exams on 198 patients (mean age, 53.5 years; 45.1% female), received from 50 referring facilities. Head CT was the most common imaging exam referred for second opinion. Forty-one of 370 exams (11%) were submitted for self-pay, and 43 (12%) were written off as free care. The remaining 286 exams (77%) were submitted for reimbursement of the professional fee only. Ultimately, of the 286 exams submitted, 260 (91%) were reimbursed for professional fees, 199 (70%) on the initial submission. Of 29 health plans contracted with our facility, 22 ultimately approved all claims made. Three plans denied all claims submitted. The largest payer was Medicare, which reimbursed 88 of 90 submitted claims. Clinical intake forms were available for 184 exams on 107 patients (mean age, 52.7 years, 43.0% female). Trauma was the most common indication, or history, provided (55% of 184 exams, 40% of 107 patients). An outside report of some form was available for 112 of the 184 exams (61%), although only 18 were formal, signed radiology reports from the referring facility. Discrepancies between available outside reports and second-opinion interpretations were noted for 17 out of 112 exams. Need for reimaging was substantially curtailed, with only ten exams repeated within 24 h. A formal process for issuing second-opinion interpretations of cross-sectional exams performed at outside institutions is feasible in the emergency department setting. In the majority of cases, reimbursement for full professional fees can be obtained.

Hemangioblastomas are rare vascular tumors most often found in the posterior fossa and cervical spinal cord and commonly associated with von Hippel-Lindau Disease. We report a case of sporadic hemangioblastoma in a patient without von Hippel-Lindau Disease. Imaging characteristics included a solid, suprasellar mass that was homogeneously enhancing. These findings most resembled a pituicytoma or choroid glioma because of the close association with the infundibulum and the homogeneous avid enhancement. Microscopically, the neoplasm was seen to be composed of vascular channels associated with foamy stromal cells, containing clear cytoplasmic vacuoles. Microscopic and immunohistochemical findings were consistent with hemangioblastoma. Hemangioblastomas are a rare form of vascular tumor most commonly associated with von-Hippel Lindau disease. Our finding of non-cystic hemangioblastoma arising from the infundibulum demonstrates that, while rare, hemangioblastomas should be considered on the differential diagnosis for an avidly enhancing suprasellar mass.

Usher syndrome (or Hallgren syndrome) is an autosomal recessive genetic disorder characterized by sensorineural deafness, retinitis pigmentosa, and variable vestibular deficit; Usher syndrome type II is the most common form. Various neuropsychiatric disorders have been reported to occur in those with Usher syndrome, including schizophrenia-like disorder, atypical psychosis, recurrent depressive illness, neurotic disorder, and mental retardation; however, bipolar disorder is not common in those with Usher syndrome. Herein we describe a 30-year-old male with Usher syndrome type II that developed features indicative of a probable manic episode. The patient had complete remission of symptoms in response to treatment with olanzapine 20 mg d-1. In persons with dual sensory impairment there are inherent problems with assessment and diagnosis is difficult due to their limited communication abilities. The diagnosis of Usher syndrome depends heavily on behavioral observation and disturbances in vegetative functions.

Hepatic Stellate Cells Alter Liver Immune Environment to Promote Cancer | Center for Cancer Research

Cancer.gov

Hepatocellular carcinoma (HCC) is the most common form of liver cancer, accounting for up to 90 percent of cases, and is the second most common cause of cancer-related deaths worldwide according to the World Health Organization’s 2014 World Cancer Report. Even when caught early, HCC often recurs, either from intra-liver metastases or new primary tumors, and recurrence is the leading cause of death for patients with HCC. The liver microenvironment is an important contributor to HCC initiation and progression and also likely plays a role in tumor recurrence. Xin Wei Wang, Ph.D., of CCR’s Laboratory of Human Carcinogenesis, and his colleagues wondered whether activated hepatic stellate cells (A-HSCs), stromal cells in the liver known to participate in repair following injury and in the development of fibrosis, contribute directly to HCC recurrence.

Stoma dermatitis: prevalent but often overlooked.

Agarwal, Shilpa; Ehrlich, Alison

2010-01-01

Peristomal dermatoses commonly afflict the area around stoma openings in ostomy patients. These complications, however, are often unreported by patients and remain untreated for years, thus affecting maintenance and recovery from the surgery. These dermatoses can have chemical, mechanical, irritant, bacterial, immunologic, or disease-related etiologies. Examples of common forms of dermatitis that occur peristomally include fecal or urine irritant contact dermatitis, chronic papillomatous dermatitis, mechanical dermatitis, and allergic contact dermatitis. This article summarizes various skin irritations that can occur after an ostomy and also reviews previously published reports of peristomal allergic contact dermatitis. In addition, the clinical importance of identifying these dermatoses (most important, their effects on the patient's quality of life), risk factors for the skin irritations, the importance of patch testing, treatment of stoma dermatitis, and the importance of patient education and patient-doctor communication are also discussed.

Childhood migraine is a common problem among the primary complaints of the pediatric population. But for the general practitioners there are little known about clinical characteristics and management strategies. Headache practitioners commonly notice the age related differences of headache characteristics and management schedules. This paper primarily aimed to answer the question if pediatric migraine is an unmaturated form of adult migraine, by discussing the pathophysiological basis, clinical forms and management strategies.

A Rb1 promoter variant with reduced activity contributes to osteosarcoma susceptibility in irradiated mice

PubMed Central

2014-01-01

Background Syndromic forms of osteosarcoma (OS) account for less than 10% of all recorded cases of this malignancy. An individual OS predisposition is also possible by the inheritance of low penetrance alleles of tumor susceptibility genes, usually without evidence of a syndromic condition. Genetic variants involved in such a non-syndromic form of tumor predisposition are difficult to identify, given the low incidence of osteosarcoma cases and the genetic heterogeneity of patients. We recently mapped a major OS susceptibility QTL to mouse chromosome 14 by comparing alpha-radiation induced osteosarcoma in mouse strains which differ in their tumor susceptibility. Methods Tumor-specific allelic losses in murine osteosacoma were mapped along chromosome 14 using microsatellite markers and SNP allelotyping. Candidate gene search in the mapped interval was refined using PosMed data mining and mRNA expression analysis in normal osteoblasts. A strain-specific promoter variant in Rb1 was tested for its influence on mRNA expression using reporter assay. Results A common Rb1 allele derived from the BALB/cHeNhg strain was identified as the major determinant of radiation-induced OS risk at this locus. Increased OS-risk is linked with a hexanucleotide deletion in the promoter region which is predicted to change WT1 and SP1 transcription factor-binding sites. Both in-vitro reporter and in-vivo expression assays confirmed an approx. 1.5 fold reduced gene expression by this promoter variant. Concordantly, the 50% reduction in Rb1 expression in mice bearing a conditional hemizygous Rb1 deletion causes a significant rise of OS incidence following alpha-irradiation. Conclusion This is the first experimental demonstration of a functional and genetic link between reduced Rb1 expression from a common promoter variant and increased tumor risk after radiation exposure. We propose that a reduced Rb1 expression by common variants in regulatory regions can modify the risk for a malignant transformation of bone cells after radiation exposure. PMID:25092376

The impact of abuse and mood on bowel symptoms and health-related quality of life in irritable bowel syndrome (IBS).

Irritable bowel syndrome (IBS) is a common abdominal pain disorder without an organic explanation. Abuse histories (physical, sexual, emotional) are prevalent in IBS. While abuse relates to mood disorders (depression and anxiety) also common in IBS, the influence of abuse on gastrointestinal (GI) symptoms and health-related quality of life (HRQOL) and its independence from psychological symptom comorbidity has not been studied. Consecutive GI outpatients completed the ROME III Research Diagnostic Questionnaire and questionnaires on trauma (Life-Stress Questionnaire), mood (Beck Depression/Anxiety Inventories), somatic symptoms (PHQ-12), and HRQOL (SF-36). Current GI symptom severity and bother were assessed using 10-cm Visual Analog Scales. 272 ROME-defined IBS (47.6 ± 0.9 years, 81% female) and 246 non-FGID (51.6 ± 1.0 years, 65% female) subjects participated. IBS patients reported greater rates of physical, sexual, and emotional abuse (p < 0.006 each), and higher depression, anxiety, and somatic symptoms (p < 0.001). Greater bowel symptom bother (7.4 ± 0.2 vs 6.7 ± 0.2, p = 0.040), severity (7.7 ± 0.2 vs 6.5 ± 0.2, p < 0.001), recent symptomatic days (9.8 ± 0.4 vs 8.5 ± 0.3, p = 0.02), and poorer HRQOL (40.9 ± 2.3 vs 55.5 ± 1.7, p < 0.001) were noted in IBS with abuse. Abuse effects were additive, with greater IBS symptom severity and poorer HRQOL noted in cases with multiple forms of abuse. Mediation analyses suggested that abuse effects on GI symptoms and HRQOL were partially mediated by mood. Abuse experiences common among IBS sufferers are associated with reports of greater GI symptoms and poorer HRQOL, particularly in those with multiple forms of abuse; this relationship may be partially mediated by concomitant mood disturbances. © 2016 John Wiley & Sons Ltd.

The prevalence of urinary tract infection in children with severe acute malnutrition: a narrative review

PubMed Central

Uwaezuoke, Samuel N

2016-01-01

This article aims to review the current evidence which shows that the prevalence of urinary tract infection (UTI) has been increasing in children with severe acute malnutrition (SAM). UTI remains one of the most common causes of febrile illness in pediatric practice. Most studies conducted among hospitalized children with complicated SAM have reported high prevalence rates of UTI. Clearly, the knowledge of baseline risk of UTI can help clinicians to make informed diagnostic and therapeutic decisions in these children. From the global reports reviewed in this article, UTI prevalence rates range from as low as 6% to as high as 37% in developing countries, while the most common bacterial isolates from urine cultures are Gram-negative coliform organisms such as Escherichia coli and Klebsiella species. These findings form the basis for the current diagnostic and therapeutic guidelines for clinicians managing children with complicated SAM. With the reported high prevalence of UTI among these children and concerns over antibiotic resistance, more extensive data are required using standardized microbiological methods. Thus, the assessment of the performance of urine dipsticks and microscopy against the gold standard urine culture is an important step toward strengthening the evidence for the therapeutic guidelines for UTI in children with SAM.

Given the evidence that regular physical activity produces substantial health benefits, participation in sports, exercise, and recreation is widely encouraged. The objective of this study was to describe participation in sports, exercise, and recreational physical activities among US adults. Data from 2 national surveys of respondents age 18 years and older were analyzed. Respondents to the American Time Use Survey (ATUS) from 2003 through 2005 (N=45,246) reported all activities on 1 randomly selected survey day. Respondents to the National Health and Nutrition Examination Survey (NHANES) from 1999 through 2004 (N=17,061) reported leisure-time physical activities in the 30 days before the interview. One-quarter of adults participated in any sport, exercise, or recreational activity on a random day, and 60.9% of adults participated in any leisure-time activity in the previous 30 days. The most common types of activities were walking, gardening and yard work, and other forms of exercise. The sports and recreational activities had typical durations of 1/2 to 3 hours per session, and the exercise activities typically lasted 1 hour or less. The prevalence of sports, exercise, and recreational physical activities is generally low among US adults; exercise is the most commonly reported type of activity.

In 1990, an outbreak of a febrile illness with high mortality was reported in border villages, later spreading to other areas of Borno State of Nigeria. To present a report of the investigation of that outbreak, with emphasis on the characterisation of hospitalised patients. Selected centres reporting cases of acute febrile illness during the months of August to December, 1990 were visited, to establish surveillance. Case investigation forms were used to obtain clinical and demographic data; and blood samples were obtained from patients for analyses. Only hospitalised patients with adequate clinical information from three centres were included in the analysis. The outbreak, which involved five of the six health zones in the state, and spread into adjoining Gongola state and the Cameroun Republic, was caused by the yellow fever virus. Fever, central nervous system (CNS) involvement, jaundice and haemorrhage were the most common clinical manifestations of 102 hospitalised patients. Eighty -three (81%) of hospitalised patients died and most within two days of admission. CNS manifestations were more common in dying patients than in survivors. The reasons for this rare outbreak of yellow fever in the dry Savannah belt of Borno State remain unclear. Improved surveillance and more effective prevention strategies are needed to avert the recurrence of such outbreaks.

Carnitine palmitoyltransferase (CPT) II deficiency, an inherited disorder of mitochondrial long-chain fatty-acid (LCFA) oxidation, results in two distinct clinical act phenotypes, namely, an adult (muscular) form and an infantile (hepatocardiomuscular) form. The rationale of this phenotypic heterogeneity is poorly understood. The adult form of the disease is commonly ascribed to the Ser-113-Leu substitution in CPT II. Only few data are available regarding the molecular basis of the infantile form of the disease. We report herein a homozygous A-2399-C transversion predicting a Tyr-628-Ser substitution in a CPT II-deficient infant. In vitro expression of mutant cDNA in COS-1 cells demonstrated the responsibilitymore » of this mutation for the disease. Metabolic consequences of the Ser-113-Leu and Tyr-628-Ser substitutions were studied in fibroblasts. The Tyr-628-Ser substitution (infantile form) resulted in a 10% CPT II residual activity, markedly impairing LCFA oxidation, whereas the Ser-113-Leu substitution (adult form) resulted in a 20% CPT II residual activity, without consequence on LCFA oxidation. These data show that CPT II activity has to be reduced below a critical threshold in order for LCFA oxidation in fibroblasts to be impaired. The hypothesis that this critical threshold differs among tissues could provide a basis to explain phenotypic heterogeneity of CPT II deficiency. 32 refs., 5 figs.« less

The subdwarf B star SB 290 - A fast rotator on the extreme horizontal branch

Hot subdwarf B stars (sdBs) are evolved core helium-burning stars with very thin hydrogen envelopes. To form an sdB, the progenitor has to lose almost all of its hydrogen envelope right at the tip of the red giant branch. In close binary systems, mass transfer to the companion provides the extraordinary mass loss required for their formation. However, apparently single sdBs exist as well, and their formation has been unclear for decades. The merger of helium white dwarfs leading to an ignition of core helium-burning or the merger of a helium core and a low-mass star during the common envelope phase have been proposed. Here we report the discovery of SB 290 as the first apparently single, fast-rotating sdB star located on the extreme horizontal branch, indicating that those stars may form from mergers.

The Gram-positive model organism Bacillus subtilis does not form microscopically detectable cardiolipin-specific lipid domains.

Rather than being homogenous diffusion-dominated structures, biological membranes can exhibit areas with distinct composition and characteristics, commonly termed as lipid domains. Arguably the most comprehensively studied examples in bacteria are domains formed by cardiolipin, which have been functionally linked to protein targeting, the cell division process and the mode of action of membrane-targeting antimicrobials. Cardiolipin domains were originally identified in the Gram-negative model organism Escherichia coli based on preferential staining by the fluorescent membrane dye nonylacridine orange (NAO), and later reported to also exist in other Gram-negative and -positive bacteria. Recently, the lipid-specificity of NAO has been questioned based on studies conducted in E. coli. This prompted us to reanalyse cardiolipin domains in the Gram-positive model organism Bacillus subtilis. Here we show that logarithmically growing B. subtilis does not form microscopically detectable cardiolipin-specific lipid domains, and that NAO is not a specific stain for cardiolipin in this organism.

A reduction in material usage of cold forged components while maintaining the functional requirements can be achieved using hollow or tubular preforms. These preforms are used to meet lightweight requirements and to decrease production costs of cold formed components. To increase production efficiency in common multi-stage cold forming processes, manufacturing of hollow preforms by combining the processes backward cup extrusion and piercing was established and will be discussed in this paper. Corresponding investigations and experimental studies are reported in this article. The objectives of the experimental investigations have been the detection of significant process parameters, determination of process limits for the combined processes and validation of the numerical investigations. In addition, the general influence concerning surface quality and diameter tolerance of hollow performs are discussed in this paper. The final goal is to summarize a guideline for industrial application, moreover, to transfer the knowledge to industry, as regards what are required part geometries to reduce the number of forming stages as well as tool cost.

Toxoplasmosis is an infection of worldwide distribution caused by Toxoplasma gondii, and infects a large proportion of the world population. Only under certain circumstances of severe immunosuppression can the parasite reactivate and cause disease. The most common form of presentation of this pathology in patients with positive HIV is the brain abscess. One of the extra-cerebral forms is toxoplasmic chorioretinitis, which could lead to a chronic active form of a slowly progressive retinitis. Diagnosis is made by observing the eye fundus and confirmed by the scarring obtained after specific treatment. We report a case of a patient with diabetes and positive HIV, in whom a toxoplasmic scar injury was detected in the annual retinography follow-up. A conservative therapeutic approach was decided, with regular check-ups for possible detection of disease activation. Copyright © 2012 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

We report simultaneous measurements of the mean temperature profile θ (z) and temperature variance profile η (z) near the lower conducting plate of a specially designed quasi-two-dimensional cell for turbulent Rayleigh-Bénard convection. The measured θ (z) is found to have a universal scaling form θ (z / δ) with varying thermal boundary layer (BL) thickness δ, and its functional form agrees well with the recently derived BL equation by Shishkina et al. The measured η (z) , on the other hand, is found to have a scaling form η (z / δ) only in the near-wall region with z / δ < 2 . Based on the experimental findings, we derive a new BL equation for η (z / δ) , which is in good agreement with the experimental results. The new BL equations thus provide a common framework for understanding the effect of BL fluctuations.

Progress Report on PICA Activities in Support of New Frontiers Missions

Stackpoole, Margaret; Venkatapathy, Ethiraj; Violette, Steve

2017-01-01

Phenolic Impregnated Carbon Ablator (PICA) is a TPS material that has been used in a number of previous flight missions (Stardust, MSL) and is planned for a number of future missions (OSIRIS-Rex and Mars 2020) so it has substantial flight heritage, is applicable to a wide range of missions, and is often baselined as the TPS in future NASA proposal activities. As is common with a number of TPS materials, PICA faces a supply chain issue with the rayon precursor from which the carbon fibers used in the PICA preform are derived. PICA uses a non-woven form of the rayon, which once carbonized, is used in the low-density carbon FiberForm (carbon tile) preform utilized in PICA. Current PICA uses a NASA-qualified non-domestic rayon supplier (Sniace), however the qualified supplier is no longer manufacturing the rayon materials. This activity will address PICA sustainability, by initially carbonizing the remaining stockpile of Sniace rayon precursor. A additional FiberForm manufacturing task from alternate rayon sources is also in progress.

Tularemia caused by Francisella tularensis occurs worldwide in the northern hemisphere, with great variation in geographic and temporal occurrence. It generally presents as an acute febrile disease with the major clinical presentations including the six classic forms of tularemia: ulceroglandular, glandular, oculoglandular, oropharyngeal, typhoidal, and pneumonic. In contrast to European countries, where the ulceroglandular form is more prominent, the oropharyngeal form is the most common presentation in Turkey. We present rare cases of oropharyngeal tularemia in a 16-year-old boy and nine-year-old girl. To the best of our knowledge, these are the firstly described abdominal lymphadenopathy cases from Turkey. The second case was admitted with erythema nodosum, and abdominal lymphadenopathy was detected during the investigation. Excisional lymph node biopsy revealed abdominal tularemia. It is necessary to consider tularemia in the differential diagnosis of abdominal lymphadenopathy in tularemia regions. We also conclude that oropharyngeal tularemia can cause lymphadenopathy in any part of the gastrointestinal tract.

We report that hypofunctional alleles of WNT1 cause autosomal-recessive osteogenesis imperfecta, a congenital disorder characterized by reduced bone mass and recurrent fractures. In consanguineous families, we identified five homozygous mutations in WNT1: one frameshift mutation, two missense mutations, one splice-site mutation, and one nonsense mutation. In addition, in a family affected by dominantly inherited early-onset osteoporosis, a heterozygous WNT1 missense mutation was identified in affected individuals. Initial functional analysis revealed that altered WNT1 proteins fail to activate canonical LRP5-mediated WNT-regulated β-catenin signaling. Furthermore, osteoblasts cultured in vitro showed enhanced Wnt1 expression with advancing differentiation, indicating a role of WNT1 in osteoblast function and bone development. Our finding that homozygous and heterozygous variants in WNT1 predispose to low-bone-mass phenotypes might advance the development of more effective therapeutic strategies for congenital forms of bone fragility, as well as for common forms of age-related osteoporosis.

Rethinking the architectural design concept in the digital culture (in architecture's practice perspective)

NASA Astrophysics Data System (ADS)

Prawata, Albertus Galih

2017-11-01

The architectural design stages in architectural practices or in architectural design studio consist of many aspects. One of them is during the early phases of the design process, where the architects or designers try to interpret the project brief into the design concept. This paper is a report of the procedure of digital tools in the early design process in an architectural practice in Jakarta. It targets principally the use of BIM and digital modeling to generate information and transform them into conceptual forms, which is not very common in Indonesian architectural practices. Traditionally, the project brief is transformed into conceptual forms by using sketches, drawings, and physical model. The new method using digital tools shows that it is possible to do the same thing during the initial stage of the design process to create early architectural design forms. Architect's traditional tools and methods begin to be replaced effectively by digital tools, which would drive bigger opportunities for innovation.

2013-03-01

The ascomycete class Pezizomycetes (single order Pezizales)is known for its cup-shaped fruit bodies and the evolution of edible truffles and morels, but little is known about the ontogeny and ecology of this large and ecologically diverse fungal group. In this issue of Molecular Ecology, Healy et al. (2013) make a great leap forward by describing and identifying asexual, anamorphic structures that produce mitotic spores in many ectomycorrhiza-forming truffle and nontruffle species on soil surfaces worldwide(Fig. 1). Although such anamorphic forms have been reported sporadically from certain ectomycorrhizal and saprotrophic Pezizomycetes (e.g. Warcup 1990), Healy et al. (2013) demonstrate that these terricolous asexual forms are both taxonomically and geographically more widespread and, in fact, much more common than previously understood. We anticipate that deeper insight into other substrates, provided by molecular analyses of materials such as dead wood and seeds, is likely to reveal numerous anamorphs of saprotrophic and pathogenic Pezizomycetes as well (see Marek et al. 2009).

Diabetes insipidus (DI) is a condition with heterogeneous clinical symptoms characterized by polyuria (urine output >4 mL/kg/hr) and polydipsia (water intake >2 L/m 2/d). In children, acquired nephrogenic DI (NDI) is more common than central DI (CDI). Diagnosis is based on the presence of high plasma osmolality and low urinary osmolality with significant water diuresis. A water deprivation test with vasopressin challenge, though has limitations, is done to differentiate NDI from CDI and diagnose their incomplete forms. Neonates and young infants are better managed with hydration therapy alone. Older children with CDI are treated with desmopressin (1-deamino-8-D-arginine vasopressin, dDAVP). Its oral form is safe, highly effective and has dosing flexibility. We report a case of an 8-year-old male patient with CDI with severe bilateral non-obstructive hydronephrosis and megaureter. Dramatic clinical and radiological responses to dDAVP treatment were achieved and therapy reduced urine volume and led to marked radiological improvement in hydronephrosis. PMID:26600892

Diabetes insipidus (DI) is a condition with heterogeneous clinical symptoms characterized by polyuria (urine output >4 mL/kg/hr) and polydipsia (water intake >2 L/m (2)/d). In children, acquired nephrogenic DI (NDI) is more common than central DI (CDI). Diagnosis is based on the presence of high plasma osmolality and low urinary osmolality with significant water diuresis. A water deprivation test with vasopressin challenge, though has limitations, is done to differentiate NDI from CDI and diagnose their incomplete forms. Neonates and young infants are better managed with hydration therapy alone. Older children with CDI are treated with desmopressin (1-deamino-8-D-arginine vasopressin, dDAVP). Its oral form is safe, highly effective and has dosing flexibility. We report a case of an 8-year-old male patient with CDI with severe bilateral non-obstructive hydronephrosis and megaureter. Dramatic clinical and radiological responses to dDAVP treatment were achieved and therapy reduced urine volume and led to marked radiological improvement in hydronephrosis.

In recent years, there has been an increase in the reports indicating a form of headache that occurs during commercial aircraft travel. This headache, called airplane headache by some authors, is believed to be a new type of headache. The headache has very specific characteristics and all of the cases exhibited very stereotypical symptoms. The headache starts suddenly during the ascent and/or descent of the commercial aircraft. It has a mean duration of 20 minutes, which is usually unilateral and commonly localized to periorbital region. The headache is described to be severe, and has a stabbing or jabbing nature, and generally subsides in a short time. In some cases, an organic cause can be identified whereas in others no organic pathology could be found. We described the clinical features of 22 cases who suffered from a headache that occurred during airplane travel. We examined other cases with similar features reported in the literature and proposed preliminary diagnostic criteria for this new form of headache. We also discussed the possible patholophysiological mechanisms that may cause this headache.

Although splenic artery aneurysms (SAAs) are common, their giant forms (more than 10 cm in diameter) are rare. Because of the variety of forms and locations of these aneurysms, there are a lot of therapeutic methods to choose. In our case of a giant true aneurysm we performed an endovascular embolization with N-butyl-cyano-acrylate (NBCA) glue. To our knowledge it is the first reported case of this method of treatment of true giant SAA. A 74-year-old male patient with symptomatic giant SAA (13 cm) was urgently admitted to our hospital for the diagnostic and therapeutic procedures. Due to the general health condition, advanced age and the large size of the aneurysm we decided to perform an endovascular treatment with N-butyl-cyano-acrylate (NBCA) glue. The preaneurysmal part of splenic artery was occluded completely with exclusion of the aneurysm. No splenectomy was needed. The patient was discharged in good general condition Embolization with NBCA can be an efficient method to treat the giant SAA.

The Society for Academic Continuing Medical Education commissioned a study to clarify and, if possible, to standardize the terminology for a set of important educational interventions. In the form of a guideline, this article describes one such intervention, performance measurement and feedback, which is a common intervention in health professions education. In the form of a summary report, performance measurement and feedback is an opportunity for clinicians to view data about the care they provide compared with some standard and often with peer and benchmark comparisons. Based on a review of recent evidence and a facilitated discussion with the US and Canadian experts, we describe proper terminology for performance measurement and feedback and other important information about the intervention. We encourage leaders and researchers to consider and build on this guideline as they plan, implement, evaluate, and report efforts with performance measurement and feedback. Clear and consistent use of terminology is imperative, along with complete and accurate descriptions of interventions, to improve the use and study of performance measurement and feedback.

Aim: The aim of this study is to determine the etiology, frequency of mandibular fractures among different age and sex, to determine the frequency of anatomic distribution, and to report the different modalities of treatment provided to the patients reported at our institution from February 2008 to September 2009. Materials and Methods: All patients fulfilling the selection criteria and having mandible fracture were selected for the study. Patient information was collected by means of a medical data form specifically designed for the present study. The values were subjected to Z and Chi-square tests. Results: Out of 35 patients, thirty one were males (88.57%) and four were females (11.43%) with a male:female ratio of 8:1. We found a peak occurrence in young adults, aged 21-30 years (n = 15, 42.86%). In case of etiology of fracture, road traffic accidents (RTAs) was the most common (n = 25, 71.43%) and condyle was most frequently involved site (n = 19, 38.78%). In most (n = 16, 45.71%) of the patients, an open reduction and rigid internal fixation using bone plate and screws was done. Conclusion: In the present study, the prevalence of mandible fractures was more prevalent in male patients, especially during the 3rd decade of life. The most common cause was road traffic accident and the more frequently affected region was condyle of the mandible. Open reduction and rigid internal fixation using miniplates and screws was the most commonly used treatment. PMID:24778980

Although it is common practice to administer pre-participation examinations (PPE) of athletes prior to training, there are no clearly established formats. Elements integral to the PPE fall within the scope of physical therapist practice, and are often categorized as a form of primary prevention for musculoskeletal disorders as defined in the Guide to Physical Therapist Practice. The purpose of this study is to describe the design and implementation of a PPE for a women's professional (gridiron) football team. The results and findings from this PPE provide one of the first musculoskeletal profiles and information about selected physical characteristics from members of a female professional football team. Players from the Kentucky Karma women's football team, a member of the National Women's Football League (NWFA), volunteered to participate in a PPE. Of twenty-five eligible team members, thirteen consented to participate. The PPE consisted of a health history questionnaire, a musculoskeletal screening, and a series of physical performance and agility tests. The players' average (± SD) age, height, weight, body mass index (BMI), and body fat percentage were 29.6 (± 5.6) yrs., 1.66 (± .05) m, 66.8 (± 12.6) kg, 24.1 (± 3.7), and 27.4 (± 6.6) %, respectively. Commonly reported injuries were similar to those reported in men's collegiate football. This is one of the first papers to report on a model PPE for a women's professional football team. Future research is needed to establish a standard PPE, recognize common injuries, and develop prevention strategies unique to women's professional football.

Complementary and alternative medicine (CAM) therapies have become increasingly popular and are used regularly by patients with chronic neurological disorders. The prevalence and characteristics of CAM use by patients with peripheral neuropathy is unknown. We performed a prospective, questionnaire-based study to determine the prevalence and patterns of use of CAM therapies in 180 consecutive outpatients with peripheral neuropathy. The use of CAM was reported by 77 patients (43%) with neuropathy. The most frequent were megavitamins (35%), magnets (30%), acupuncture (30%), herbal remedies (22%), and chiropractic manipulation (21%); 37 (48%) tried more than one form of alternative treatment. Seventeen respondents (27%) thought their neuropathy symptoms improved with these approaches. Those who used CAM were slightly younger (mean age 62 vs. 65 years, p = 0.05) and more often college educated (39% vs. 24%, p = 0.03) compared to CAM nonusers. They also more often reported burning neuropathic pain (62% vs. 44%, p = 0.01). Patients with diabetic neuropathy used CAM more frequently than others (p = 0.03). The most common reason for using CAM was inadequate pain control (32%). Almost half of patients did not consult a physician before starting CAM. We conclude that there is a high prevalence of CAM use in our patients with neuropathy, and one-quarter reported that their symptoms improved. CAM users were better educated than nonusers, but most did not discuss CAM treatments with their physician. Neuropathic pain was substantially more common in CAM users, and lack of pain control was the most common reason for CAM use.

High intakes of fruit and vegetables may reduce the risk of cancer at several sites. Evidence has been derived mainly from case-control studies. We reviewed the relationship between consumption of vegetables and fruit and the risk of several common cancers in a network of Italian and Swiss case-control studies including over 10,000 cases of fourteen different cancers and about 17,000 controls. Data were suggestive of a protective role of vegetable intake on the risk of several common epithelial cancers. OR for the highest compared with the lowest levels of consumption ranged from 0.2 (larynx, oral cavity and pharynx) to 0.9 (prostate). Inverse associations were found for both raw and cooked vegetables, although for upper digestive tract cancers the former were somewhat stronger. Similar inverse associations were found for cruciferous vegetables. Frequent consumption of allium vegetables was also associated with reduced risk of several cancers. Fruit was a favourable correlate of the risk of several cancers, particularly of the upper digestive tract, with associations generally weaker than those reported for vegetables. A reduced risk of cancers of the digestive tract and larynx was found for high consumption of citrus fruit. Suggestive protections against several forms of cancer, mainly digestive tract cancers, were found for high consumption of apples and tomatoes. High intakes of fibres, flavonoids and proanthocyanidins were inversely related to various forms of cancer. In conclusion, data from our series of case-control studies suggested a favourable role of high intakes of fruit and vegetables in the risk of many common cancers, particularly of the digestive tract. This adds evidence to the indication that aspects of the Mediterranean diet may have a favourable impact not only on CVD, but also on several common (epithelial) cancers, particularly of the digestive tract.

Common and rare forms of diabetes mellitus: towards a continuum of diabetes subtypes.

Insights into the genetic basis of type 2 diabetes mellitus (T2DM) have been difficult to discern, despite substantial research. More is known about rare forms of diabetes mellitus, several of which share clinical and genetic features with the common form of T2DM. In this Review, we discuss the extent to which the study of rare and low-frequency mutations in large populations has begun to bridge the gap between rare and common forms of diabetes mellitus. We hypothesize that the perceived division between these diseases might be due, in part, to the historical ascertainment bias of genetic studies, rather than a clear distinction between disease pathophysiologies. We also discuss possible implications of a new model for the genetic basis of diabetes mellitus subtypes, where the boundary between subtypes becomes blurred.

Communicating With Patients: Skills Assessment in US Colleges of Pharmacy

PubMed Central

2006-01-01

Objective To describe current practices in assessing patient communication skills in US colleges and schools of pharmacy. Methods Syllabi and behavioral assessment forms were solicited and key faculty members were interviewed. Forms were analyzed to determine skills most commonly assessed in communication with simulated or role-playing patients. Results Fifty schools submitted behavioral assessment forms for patient communication skills. Individuals from 47 schools were interviewed. Colleges were found to vary in the way communication skills were assessed. Assessment forms focused more on dispensing a new prescription than monitoring ongoing therapy. Providing information was emphasized more than promoting adherence. Common faculty concerns were lack of continuity and congruence of assessment across the curriculum. Conclusions A common understanding of the standards and procedures for determining competence is needed. Experience and assessment activities should be sequenced throughout a program to build competence. PMID:17136187

The transitional period between the oncosphere and the cysticercus of Taenia solium is the postoncospheral (PO) form, which has not yet been completely characterized. The aim of this work was to standardize a method to obtain T. solium PO forms by in vitro cultivation. We studied the morphology of the PO form and compared the expression of antigenic proteins among the PO form, oncosphere, and cysticerci stages. T. solium activated oncospheres were co-cultured with ten cell lines to obtain PO forms, which we studied at three stages of development--days 15, 30, and 60. A high percentage (32%) of PO forms was obtained using HCT-8 cells in comparison to the other cell lines. The morphology was observed by bright field, scanning, and transmission electron microscopy. Morphology of the PO form changed over time, with the six hooks commonly seen in the oncosphere stage disappearing in the PO forms, and vesicles and microtriches observed in the tegument. The PO forms grew as they aged, reaching a diameter of 2.5 mm at 60 days of culture. 15-30 day PO forms developed into mature cysticerci when inoculated into rats. Antigenic proteins expressed in the PO forms are also expressed by the oncosphere and cysticerci stages, with more cysticerci antigenic proteins expressed as the PO forms ages. This is the first report of an in vitro production method of T. solium PO forms. The changes observed in protein expression may be useful in identifying new targets for vaccine development. In vitro culture of PO form will aid in understanding the host-parasite relationship, since the structural changes of the developing PO forms may reflect the parasite's immunoprotective mechanisms. A wider application of this method could significantly reduce the use of animals, and thus the costs and time required for further experimental investigations.

Disconcordance in Statistical Models of Bisphenol A and Chronic Disease Outcomes in NHANES 2003-08

Background Bisphenol A (BPA), a high production chemical commonly found in plastics, has drawn great attention from researchers due to the substance’s potential toxicity. Using data from three National Health and Nutrition Examination Survey (NHANES) cycles, we explored the consistency and robustness of BPA’s reported effects on coronary heart disease and diabetes. Methods And Findings We report the use of three different statistical models in the analysis of BPA: (1) logistic regression, (2) log-linear regression, and (3) dose-response logistic regression. In each variation, confounders were added in six blocks to account for demographics, urinary creatinine, source of BPA exposure, healthy behaviours, and phthalate exposure. Results were sensitive to the variations in functional form of our statistical models, but no single model yielded consistent results across NHANES cycles. Reported ORs were also found to be sensitive to inclusion/exclusion criteria. Further, observed effects, which were most pronounced in NHANES 2003-04, could not be explained away by confounding. Conclusions Limitations in the NHANES data and a poor understanding of the mode of action of BPA have made it difficult to develop informative statistical models. Given the sensitivity of effect estimates to functional form, researchers should report results using multiple specifications with different assumptions about BPA measurement, thus allowing for the identification of potential discrepancies in the data.

Although foodborne diseases are an important public health problem worldwide, the burden of foodborne illness is not well described in most Pacific Island Countries and Territories. Laboratory-based surveillance programs can detect trends and outbreaks, estimate burden of illness, and allow subtyping of enteric pathogens (e.g. Salmonella serotyping), which is critical for linking illness to food vehicles and animal reservoirs. To enhance public health capacity in Fiji for foodborne disease surveillance, we developed the Salmonella Surveillance Project (SSP), a collaboration to pilot laboratory-based surveillance for Salmonella. A network of national and international partners was formed including epidemiologists, microbiologists, and environmental health personnel. Ministry of Health personnel were trained in foodborne disease surveillance and outbreak investigation. Three clinical microbiology laboratories from different parts of the country functioned as sentinel sites, reporting all laboratory-confirmed Salmonella infections using a standardized case report form. Non-Typhi Salmonella isolates were collected for serotyping. In 2004-2005, 86 non-Typhi Salmonella and 275 S. Typhi laboratory-confirmed infections were reported. Salmonella enterica serotype I 3,10: r:- and Salmonella enterica serotype Weltevreden were the most commonly isolated non-Typhi serotypes. In Fiji, the SSP utilized international partnerships to facilitate training, and to enhance laboratory capacity and surveillance for salmonellosis. Incorporating laboratory-based foodborne disease reporting into national disease surveillance will enable public health officials to describe the burden of foodborne illness, identify outbreaks, conduct analytic epidemiology studies, and improve food safety.

Emergency medical technicians (EMTs) in Iran experience concerning levels of workplace violence, although until now there has been no investigation of this phenomenon. The objectives of the present study were to describe the exposure of Iranian EMTs to workplace violence and to identify the importance of related factors from their viewpoint. In this descriptive, exploratory study, 160 EMTs agreed to participate in a survey that collected data regarding their exposure to the following forms of workplace violence: verbal abuse, physical assault, cultural harassment, sexual harassment and sexual assault. A total of 138 questionnaires were returned, representing a response rate of 86%. The majority of participants 75% (n = 103) experienced at least one form of workplace violence in the 12 months before completing the questionnaire. The most frequently reported form of workplace violence was verbal abuse (71%), followed by physical assault (38%) and cultural harassment (9%). Violence resulting in serious injuries was reported by only 4% of participants, with no more than 8% of participants experiencing workplace violence that included the use of weapons. The most reported response to workplace violence was to 'invite the offender to calm down'. Participants took this approach because they believed that 'follow up of workplace violence is ineffectual' (34%), considered the workplace violence as a common in their job (30%), and did not know whom to report workplace violence to (13%). Iranian EMTs experience a considerable amount of workplace violence. The present study highlights the recommendation for formal training programmes and clearer protocols about how to manage workplace violence, especially verbal abuse in the Iranian prehospital setting. © 2011 The Authors.

A significant proportion of severe familial forms of obesity remain genetically elusive. Taking advantage of our unique cohort of multigenerational obese families, we aimed to assess the contribution of rare mutations in 29 common obesity-associated genes to familial obesity, and to evaluate in these families the putative presence of nine known monogenic forms of obesity. Through next-generation sequencing, we sequenced the coding regions of 34 genes involved in polygenic and/or monogenic forms of obesity in 201 participants (75 normal weight individuals, 54 overweight individuals and 72 individuals with obesity class I, II or III) from 13 French families. In vitro functional analyses were performed to investigate the mutation PCSK1-p.Arg80* which was identified in a family. A novel heterozygous nonsense variant in PCSK1 (p.Arg80*), encoding a propeptide truncated to less than two exons (out of 14), was found to co-segregate with obesity in a three-generation family. We demonstrated that this mutation inhibits PCSK1 enzyme activity and that this inhibition most likely does not involve a strong physical interaction. Furthermore, both mutations PCSK1-p.Asn180Ser and POMC-p.Phe144Leu, which had previously been reported to be associated with severe obesity, were also identified in this study, but did not co-segregate with obesity. Finally, we did not identify any rare mutations co-segregating with obesity in common obesity susceptibility genes, except for CADM2 and QPCTL, where we found two novel variants (p.Arg81His and p.Leu98Pro, respectively) in three obese individuals. We showed for the first time that a nonsense mutation in PCSK1 was likely to cause dominantly inherited human obesity, due to the inhibiting properties of the propeptide fragment encoded by the null allele. Furthermore, the present family sequencing design challenged the contribution of previously reported mutations to monogenic or at least severe obesity.

Α case of a chronic idiopathic form of a severe type of Restless Legs Syndrome (RLS), which developed during pregnancy and persisted after this, misdiagnosed for 34 years as radiculopathy S1, is reported. In spite of the thorough clinical and laboratory investigation, in addition to constant changes of the therapeutic approach, the diagnosis of S1 radiculopathy could not be confirmed, resulting in a chronic clinical course; the latter was characterized by relapses and remissions not attributed or linked in any way to the treatment (various types of). In fact, it was due to a routine workup in a sleep clinic, where the patient was referred because of a coincident chronic insomnia (Restless Legs Syndrome is a known and important cause of insomnia/chronic insomnia), which resulted in a proper diagnosis and treatment of this case. With the use of Restless Legs Syndrome appropriate treatment (Pramipexole 0.18 mg taken at bedtime, a dopaminergic agent and Level A recommended drug for Restless Legs Syndrome) an excellent response and immediate elimination of symptoms was achieved. Restless Legs Syndrome may present with a variety of symptoms (with the most prominent shortly being reported with the acronym URGE: Urge to move the legs usually associated with unpleasant leg sensations, Rest induces symptoms, Getting active brings relief, Evening and night deteriorate symptoms); given the fact that Restless Legs Syndrome presents with a great variety and heterogeneity of symptoms (mostly pain, dysesthesia and paresthesia), which may occur in several other diseases (the so called "RLS mimics"), proper diagnosis of Restless Legs Syndrome usually fails. Restless Legs Syndrome misinterpreted as S1 radiculopathy, to the best of our knowledge, has not been reported yet in the literature. Here, case history, clinical course and common RLS mimics are presented. Different forms of Restless Legs Syndrome manifestations, which are commonly -as in this case- misinterpreted due to their mimicking several pathological conditions, Restless Legs Syndrome prevalence on general population according to various large epidemiological studies and pathogenic hypotheses on the issue of Restless Legs Syndrome are discussed. Finally, by presenting another possible "RLS-mimic" our aim is to highlight the common misdiagnosis of Restless Legs Syndrome, which can mimic a variety of disorders, some of which are very common, such as an S1 radiculopathy, thus raising concern among doctors of various specialties addressed to by Restless Legs Syndrome sufferers, on the importance of proper diagnosis of the syndrome.

Approximately 70% of homeless youth smoke cigarettes, but their use of alternative tobacco products (ATPs) is unknown. This paper reports on ATP use among past-month smokers in Los Angeles County, including whether it differs by demographic characteristics, homelessness severity, past-year quit attempts, and readiness to quit smoking. Given the growing popularity of e-cigarettes, we also report on perceptions of harm and reasons for using this product. We surveyed 292 unaccompanied homeless youth who were randomly sampled from street sites. Participants had smoked at least 100 cigarettes during their lifetime and 1 cigarette during the past month. Seventy-two percent of youth reported past-month ATP use (e-cigarettes = 51%; little cigars/cigarillos = 46%; hookah = 31%; other smokeless tobacco product = 24%; chewing tobacco/moist snuff = 19%). Current ATP use was unrelated to most demographic characteristics or having a past-year quit attempt. However, youth who planned to quit smoking in the next 30 days were significantly less likely to report current use of hookahs, other smokeless tobacco products, or e-cigarettes. Among lifetime e-cigarette users, the most common reasons for use included not having to go outside to smoke (38%) and being able to deal with situations or places where they cannot smoke (36%); it was less common to report using e-cigarettes to quit smoking (17%-18%). Dual use of ATPs among homeless youth smokers is common and is more likely among those who have no immediate plans to quit smoking. Effective and easily disseminable strategies for reducing all forms of tobacco use among homeless youth are urgently needed.

Superolateral dislocation of the intact mandibular condyle (SDIMC) is rare. This case report focuses on a 15-year-old teenager who was involved in a motor vehicle accident as well a literature review regarding the SDIMC. Clinical examination demonstrated a diffuse edema in the midfacial area and a left lateral deflection of the mandible, including an open bite and a crepitation in the symphyseal region. Three-dimensional computed tomography scans were taken, which presented a superolateral dislocation of the left mandibular condyle as well as panfacial fracture. The patient was set in intermaxillary fixation for 2 weeks and underwent subsequent active jaw physiotherapy, the evaluation of which presented satisfactory results. This case study also presents a literature review, which demonstrated 21 well-documented cases of SDIMC. The patients' mean age was of 29 years. The male gender proved to be more prevalent, with road traffic collisions representing the most common form of accident. Type II, with unilateral dislocation, proved to be the most common. The mean reduction time was 7 days. The open methods were the most commonly used reduction methods. Mandible fracture was associated with dislocation in 82% of the cases, with other facial fractures appearing in only 23% of the cases. Patient follow up presented satisfactory results in 59% of the cases. © 2011 John Wiley & Sons A/S.

Cystic fibrosis (CF) is the most common lethal inherited disease in the white population. It is characterized by exocrine gland epithelia dysfunction, which leads to pulmonary and pancreatic insufficiency. Since the cloning of the CF gene in 1989 and the identification of the most common CF mutation (delta F508), more than 400 different mutations have been described. These mutations appear to contribute to the heterogeneity of the CF phenotype and several reports have speculated on the relationship between the most common CF mutations and the patient's clinical status. We report the case of a 21-year-old woman with longstanding chronic pansinusitis, nasal polyposis, chronic cough and severe nasal crusting. During a period of five years she had been followed by her otolaryngologist and pediatric pulmonologist. Sweat tests performed at the age of 17 and 18 were within normal limits and she underwent repeated conventional sinonasal procedures, with no improvement in her clinical status. On her present admission, sweat tests showed a 70 meq/l chloride concentration. The diagnosis of CF was then confirmed by DNA analysis and the patient was found to carry the 3849 + 10 kB C-->T mutation. The early detection of this newly recognized form of CF in adults as well as in children presenting with sinonasal symptoms is critical for life expectancy and quality.

Kennedy's disease, also known as bulbospinal muscular atrophy, is a rare, X-linked recessive neurodegenerative disorder affecting adult males. It is caused by expansion of an unstable cytosine-adenine-guanine tandem-repeat in exon 1 of the androgen-receptor gene on chromosome Xq11-12, and is characterized by spinal motor neuron progressive degeneration. Endocrinologically, these patients often have the features of hypogonadism associated to the androgen insensitivity syndrome, particularly its partial forms. We report 4 cases with the typical neurological presentation, consisting of slowly progressing generalized muscle weakness with atrophy and bulbar muscle involvement; these patients also had several endocrine manifestations; the most common non-neurological manifestation was gynecomastia. In all cases reported, molecular analysis showed an abnormal cytosine-adenine-guanine triplet repeat expansion in the androgen receptor gene. Copyright © 2014 SEEN.

Introduction Pyomyositis is a disease in which an abscess is formed deep within large striated muscles. Case presentation We report the case of a 10-year-old boy who presented with fever and a painful hip and was subsequently diagnosed with pyomyositis of the tensor fascia lata. In children with clinical and laboratory findings of inflammation in the vicinity of the hip joint, the differential diagnosis includes transient synovitis, an early stage of Legg-Calvé-Perthes disease, infectious arthritis of the hip, rheumatologic diseases and extracapsular infection such as osteomyelitis. Conclusion To the best of the authors' knowledge, this is the first report of pyomyositis of the tensor fascia lata. Although pyomyositis is a rare disease and the differential diagnosis includes a variety of other commonly observed diseases, pyomyositis should be considered in cases where children present with fever, leukocytosis and localized pain.

Anomalies of the coronary arteries are reported in 1-2% of patients among diagnostic angiogram. Ectopic origin of right coronary artery (RCA) from opposite sinus is one of the most common and they are mainly benign, but at times may be malignant. We report a case of a 69-year-old male who underwent early invasive percutaneous coronary intervention for non-ST-segment elevation myocardial infarction (NSTEMI) where RCA arising from left sinus at the root of left main artery was culprit and various technical challenges were encountered while intervening in form of cannulation to tracking of hardwares. RCA was cannulated with floating wire technique using hockey stick guide catheter and revascularized by deployment of 3.5 × 38 mm Promus Premier Everolimus eluting stent (Boston Scientific, USA). To the best of our knowledge, this is the first ever report of ectopic RCA being revascularized by using hockey stick catheter.

This paper describes the extent to which abused and neglected children report intimate partner violence (IPV) victimization and perpetration when followed up into middle adulthood. Using data from a prospective cohort design study, children (ages 0-11) with documented histories of physical and sexual abuse and/or neglect (n=497) were matched with children without such histories (n=395) and assessed in adulthood (Mage=39.5). Prevalence, number, and variety of four types of IPV (psychological abuse, physical violence, sexual violence, and injury) were measured. Over 80% of both groups - childhood abuse and neglect (CAN) and controls - reported some form of IPV victimization during the past year (most commonly psychological abuse) and about 75% of both groups reported perpetration of IPV toward their partner. Controlling for age, sex, and race, overall CAN [adjusted odds ratio (AOR)=1.60, 95% CI [1.03, 2.49

Domestic violence is globally endemic and adversely impacts the health and economic well-being of women and society. This study used the standardized and validated assessment instrument "Woman Abuse Screening Tool" to study the prevalence of various forms of domestic violence among married women. The relationship between domestic violence and consanguineous marriage was studied using the chi-squared test. Cumulatively, 1010 married women were interviewed. Emotional abuse was the most commonly reported abuse, reported by 721 (71.4%) women as either often or sometimes, followed by sexual abuse and physical abuse, reported by 527 (52.2%) and 511 (50.6%) respectively. Being married to one's cousin did not protect married women from being abused either emotionally or physically by their husbands; thsi was statistically significant. There is a need for better understanding of the magnitude and scale of domestic violence in Pakistan by using standardized assessment tools for meaningful comparisons across different parts of the country over time.

Vulvodynia is a poorly characterized condition with multiple treatment options that have been described as largely ineffective in research settings. To describe treatment patterns in women enrolled in the National Vulvodynia Registry and determine if there is an association between selected treatments and patient-reported outcomes such as pain, sexual function, and psychological distress after 6 months of treatment. Participants completed questionnaires on general medical history and patient-reported outcomes using the short-form McGill Pain Questionnaire, the Female Sexual Function Index, the Short Form-12 quality-of-life questionnaire, the Coping Strategies Questionnaire, and the State-Trait Anxiety Inventory. The evaluation also included pain sensitivity assessment of the vaginal mucosa using a cotton-tipped applicator and the vaginal muscles using a single-digit. In this prospective cohort study, all measurements were collected at baseline and again at 6 months after treatment. Type of treatment, number of treatments, self-reported pain intensity, dyspareunia, and pain-related psychological distress measures are reported at baseline and 6 months. Of 344 women enrolled, 282 received treatment; 78 different treatments were identified and categorized by type (eg, topical, oral, physical therapy) and number. The most commonly used treatments were topical (85%, n = 241), physical therapy (52%, n = 147), and oral medications (45%, n = 128). Notably, 73% of participants received ≥2 treatments. There was no association between type or number of treatments and patient characteristics. At 6 months, women reported improvements in general pain (P = .001), pain during intercourse (P = .001), catastrophizing (P = .000), and anxiety (P = .000). The Short Form-12 quality-of-life questionnaire showed improvements in physical limitations (P = .024), emotional limitations (P = .003), well-being (P = .025), and social function (P = .010). However, all domains of the Female Sexual Function Index indicated worsening in sexual function (P = .000) except for pain. Multi-modal treatments were most commonly used in clinical practice and improvements in patient-reported outcomes such as quality of life, distress, and pain were noted; however, participants who returned at 6 months continued to report poor sexual function. Strengths include a prospective and long-term study design that evaluated women in clinical settings. Limitations include a high rate of loss to follow-up for certain measures and inability to evaluate efficacy of individual treatments. In a setting where women were receiving highly specialized care, we found wide variation in the type and number of treatments used to treat vulvodynia. Despite this heterogeneity in treatment selection, women reported significant improvements in all study measures except sexual function. Lamvu G, Alappattu M, Witzeman K, et al.

Although the Wechsler Full Scale IQ (FSIQ) is a common component of most neuropsychological evaluations, there are many clinical situations where the complete administration of this battery is precluded by various constraints, including limitations of time and patient compliance. These constraints are particularly true for dementia evaluations involving elderly patients. The present study reports data on two short forms particularly suited to dementia evaluations, each requiring less than 20min of administration time. One of the short forms was previously validated in dementia for the WAIS-R [Randolph, C., Mohr, E., & Chase, T. N. (1993). Assessment of intellectual function in dementing disorders: Validity of WAIS-R short forms for patients with Alzheimer's, Huntington's, and Parkinson's disease. Journal of Clinical and Experimental Neuropsychology, 15, 743-753]; the second was developed specifically for patients with motor disabilities. These short forms were validated using the WAIS-III normative standardization sample (N=2450), neurologic sample (N=63), and matched controls (N=49), and a separate mixed clinical sample (N=70). The results suggest that each short form provides an accurate and reliable estimate of WAIS-III FSIQ, validating their use in appropriate clinical contexts. The present data support the use of these short forms for dementia evaluations, and suggests that they may be applicable for the evaluation of other neurological and neuropsychiatric disorders that involve acquired neurocognitive impairment.

Cysticercosis is a common parasitic infection caused by the larval phase of the Taenia solium, it infects humans as well as pigs. Considered an endemic parasitosis in developing countries including Latin America, Asia and Africa. Clinical manifestations of the disease can be influenced by ambient factors, host individualities and the infectious agent itself. Neurocysticercosis can be asymptomatic or present with various signs and symptoms that can vary in severity. This review is focused on analyzing the various presentations of Neurocysticercosis throughout different age groups, and special populations. We found asymptomatic presentations to be the most common form, followed by various grades of severity including in its most severe form death. The most common alterations include: epilepsy (60-90%), intracraneal hypertension (14-27%), as well as neuropsychiatric symptoms (5-52%), and focal neurological deficits (4-19%). The heterogeneity of the clinical scenario relies upon parasite factors (number, localization and stage of central nervous system [CNS] disease), host particularities (gender, age and immunologic response), and finally environmental factors. The most common form of infection is asymptomatic although there are various forms of clinical manifestations that rely upon different factors including environment, host response and the parasite itself.

Team of rivals: alliance formation in territorial songbirds is predicted by vocal signal structure

Cooperation and conflict are regarded as diametric extremes of animal social behaviour, yet the two may intersect under rare circumstances. We here report that territorial competitors in a common North American songbird species, the chipping sparrow (Spizella passerina), sometimes form temporary coalitions in the presence of simulated territorial intruders. Moreover, analysis of birds’ vocal mating signals (songs) reveals that coalitions occur nearly exclusively under specific triadic relationships, in which vocal performances of allies and simulated intruders exceed those of residents. Our results provide the first evidence that animals like chipping sparrows rely on precise assessments of mating signal features, as well as relative comparisons of signal properties among multiple animals in communication networks, when deciding when and with whom to form temporary alliances against a backdrop of competition and rivalry.

It has been asserted that criminal law and common morality are not sufficient terms to describe specific behaviors as corruption because those in power have the capacity to include or exclude certain behavior as a category in the law. Thus, corruption should not be just treated as an objective behavioral category but as a form of social censure. This article reports on a quantitative and qualitative study that collected the views of Chinese youth on the control of corruption in China. It was found that they agreed with the moral-negative judgements behind the censure of corruption, and that bureaucratic forces can be mobilised to punish the corrupt and degrade their status. Mediation analysis discovered that political functions mediate the association between the moral-negative nature and bureaucratic form of the censure of corruption and status degradation of the censured.

Did the Mississippian Lodgepole buildup at Dickinson Field (North Dakota) form as a gas seep ({open_quotes}vent{close_quotes}) community?

The Lower Mississippian Lodgepole carbonate buildup reservoir at Dickinson Field in Stark County, North Dakota, has been widely reported as being a Waulsortian (or Waulsortian-like) mound. The term {open_quotes}Waulsortian mound{close_quotes} is used for a variety of Early Mississippian carbonate buildups that share a number of features including an abundance of carbonate mud, a {open_quotes}framework{close_quotes} of organisms such as fenestrate bryozoans and crinoids that tended to trap or baffle sediment, and a general absence of marine-cemented reef framework. Although the age of the Lodgepole mound at Dickinson Field qualifies it to be a Waulsortian mound, petrographic study of cores reveals thatmore » the reservoir rocks are quite unlike those in true Waulsortian mounds. Instead of being dominated by carbonate mud, the Lodgepole mound core is dominated by marine cement. Furthermore, ostracods and microbial limestones are common in the mound core where they occur with crinoid debris and small amounts of bryozoan, coral, and brachiopod debris. The abundant microbial limestones and marine cement indicate that the Dickinson mound formed as a lithified reef on the sea floor rather than as a Waulsortian mud mound. The microbial limestones, marine cement, and common ostracods in the mount core, and the fact that the mound nucleated almost directly o top of the Bakken Shale, suggest that the Dickinson Lodgepole mound formed at the site of a submarine spring and gas seep.« less

Heart Failure in Sub-Saharan Africa

Bloomfield, Gerald S; Barasa, Felix A; Doll, Jacob A; Velazquez, Eric J

2013-01-01

The heart failure syndrome has been recognized as a significant contributor to cardiovascular disease burden in sub-Saharan African for many decades. Seminal knowledge regarding heart failure in the region came from case reports and case series of the early 20th century which identified infectious, nutritional and idiopathic causes as the most common. With increasing urbanization, changes in lifestyle habits, and ageing of the population, the spectrum of causes of HF has also expanded resulting in a significant burden of both communicable and non-communicable etiologies. Heart failure in sub-Saharan Africa is notable for the range of etiologies that concurrently exist as well as the healthcare environment marked by limited resources, weak national healthcare systems and a paucity of national level data on disease trends. With the recent publication of the first and largest multinational prospective registry of acute heart failure in sub-Saharan Africa, it is timely to review the state of knowledge to date and describe the myriad forms of heart failure in the region. This review discusses several forms of heart failure that are common in sub-Saharan Africa (e.g., rheumatic heart disease, hypertensive heart disease, pericardial disease, various dilated cardiomyopathies, HIV cardiomyopathy, hypertrophic cardiomyopathy, endomyocardial fibrosis, ischemic heart disease, cor pulmonale) and presents each form with regard to epidemiology, natural history, clinical characteristics, diagnostic considerations and therapies. Areas and approaches to fill the remaining gaps in knowledge are also offered herein highlighting the need for research that is driven by regional disease burden and needs. PMID:23597299

Hypertrophic osteoarthropathy in a young adult male from Berber, Sudan (2nd-3rd century CE).

Binder, M; Saad, M

2017-09-01

Hypertrophic osteoarthropathy (HOA) is a pathological condition characterised by extensive periosteal new bone formation (NBF) on the diaphyses of the long bones, metacarpal and metatarsal bones. In modern clinical contexts, the secondary form of the disease is common and most often occurs secondary to intra-thoracic cancer and other forms of chronic pulmonary disease. Paleopathological evidence for HOA on the other hand has only occasionally been reported. Here we report a young adult male from the Meriotic cemetery at Berber in Sudan (2nd-3rd century CE) displaying widespread NBF on the diaphyses of the upper and lower limb bones, metacarpal and metatarsal bones, as well as the pelvis and scapulae. While several pathological conditions have to be considered as differential diagnostic options for NBF in the post-cranial skeleton, HOA is the most likely diagnosis, based on the distribution of the changes observed in this individual, as well as their macroscopic and radiographic characteristics. A chronic pulmonary condition as indicated by NBF on the visceral side of the ribs may represent the underlying cause for the HOA. This individual represents the first paleopathological case of HOA reported from an archaeological site in Africa. Copyright © 2017 Elsevier Inc. All rights reserved.

Pan-brachial plexus neuropraxia following lightning: A rare case report.

PubMed

Patnaik, Ashis; Mahapatra, Ashok Kumar; Jha, Menka

2015-01-01

Neurological complications following lightning are rare and occur in form of temporary neurological deficits of central origin. Involvement of peripheral nervous system is extremely rare and only a few cases have been described in the literature. Isolated unilateral pan-brachial plexus neuropraxia has never been reported in the literature. Steroids have long been used for treatment of neuropraxia. However, their use in lightning neural injury is unique and requires special mention. We report a rare case of lightning-induced unilateral complete flaccid paralysis along with sensory loss in a young patient. Lightning typically causes central nervous involvement in various types of motor and sensory deficit. Surprisingly, the nerve conduction study showed the involvement of peripheral nervous system involvement. Steroids were administered and there was significant improvement in neurological functions within a short span of days. Patients' functions in the affected limb were normal in one month. Our case was interesting since it is the first such case in the literature where lightning has caused such a rare instance of unilateral pan-brachial plexus lesion. Such cases when seen, raises the possibility of more common central nervous system pathology rather than peripheral involvement. However, such lesions can be purely benign forms of peripheral nerve neuropraxia, which can be managed by steroid treatment without leaving any long-term neurological deficits.

Geology and ground-water resources of southeastern New Hampshire

USGS Publications Warehouse

Bradley, Edward

1964-01-01

The continued growth and development of southeastern New Hampshire, an area of about 390 square miles adjacent to the Atlantic Ocean, will depend partly on effectively satisfying the demand for water, which has increased rapidly since World War II. The report identifies and describes the principal geologic units with respect to the occurrence of ground water. These units include bedrock and the various unconsolidated deposits that mantle the bedrock surface discontinuously throughout the area. The bedrock formations, consisting of igneous and metamorphic rocks, chiefly of Paleozoic age, form a single water-bearing unit. Ground water is in joints and fractures. The fractures are small and scattered and therefore impart only a low permeability to the rocks. Wells in the bedrock commonly produce small but reliable supplies of ground water at depths of less than 150 feet. The yields of about 80 wells inventoried for this report ranged from 1? to 100 gpm (gallons per minute) and the median was 912 gpm. Depths ranged from 45 to 600 feet. The unconsolidated deposits consist of glacial drift of Pleistocene age; swamp deposits, alluvium, and beach deposits of Recent age; and eolian deposits of Pleistocene -and Recent age. For this report the glacial drift is divided into till, ice-contact deposits, marine deposits, and outwash and shore deposits. Glacial till forms a discontinuous blanket, commonly less than 15 but in some hills (drumlins) as much as about 200 feet thick. It has a low permeability but, because of its widespread outcrop area, it has been utilized as a source of water for numerous domestic supplies. Because most wells in till are shallow, many fail to meet modern demands during dry summers. Ice-contact deposits locally form kames, kame terraces, kame plains, and ice-channel fillings throughout the area. They overlie bedrock and till and range in thickness from less than 1 foot to as much as 190 feet. In general, the ice-contact deposits are coarse textured and permeable, but variations in- the physical and hydrologic properties of a single deposit and from deposit to deposit are common. Ice-contact deposits are the source of the larger ground-water supplies in southeastern New Hampshire. Marine deposits underlie lowlands and valleys to a distance of about 20 miles inland from the present coastline. They commonly overlie bedrock and till and at places overlie or are interbedded with ice-contact deposits. Marine deposits range in thickness from less than 1 foot to possibly 75 feet. They are fine textured and impermeable; they do not yield water to wells in southeastern New Hampshire but generally act as a barrier to ground-water movement. Outwash and shore deposits form broad sand plains or gently sloping terraces of small extent. At most places the outwash and shore deposits, which range in thickness from less than 1 foot to about 50 feet, overlie marine deposits, but at some places they overlie bedrock, till, or ice-contact deposits. The outwash and shore deposits are fine textured and moderately permeable. They commonly yield enough ground water to meet the needs of farms, homes, and small industries. Alluvium underlies the flood plains and channels of the principal streams and overlies bedrock and older unconsolidated deposits wherever streams cross the older units. The alluvium generally is not tapped by wells. Beach deposits occupy areas along the Atlantic Ocean between promontories of bedrock or till. In general beach deposits are permeable and are a source of water supplies for domestic use. Yields of wells are limited, however, by the danger of drawing in salty water. Recharge in southeastern New Hampshire is derived principally from precipitation on outcrop areas of ice-contact deposits and outwash and shore deposits during the nongrowing season. Ground water is discharged naturally by springs, by effluent seepage to streams and other bodies of surface water, and by evapotranspiration. It

Cholinesterase characterization of two autochthonous species of Ria de Aveiro (Diopatra neapolitana and Solen marginatus) and comparison of sensitivities towards a series of common contaminants.

PubMed

Nunes, Bruno; Resende, Sara Teixeira

Biomonitoring of chemical contamination requires the use of well-established and validated tools, including biochemical markers that can be potentially affected by exposure to important environmental toxicants. Cholinesterases (ChEs) are present in a large number of species and have been successfully used for decades to discriminate the environmental presence of specific groups of pollutants. The success of cholinesterase inhibition has been due to their usefulness as a biomarker to address the presence of organophosphate (OP) and carbamate (CB) pesticides. However, its use in ecotoxicology has not been limited to such chemicals, and several other putative classes of contaminants have been implicated in cholinesterasic impairment. Nevertheless, the use of cholinesterases as a monitoring tool requires its full characterization in species to be used as test organisms. This study analyzed and differentiated the various cholinesterase forms present in two autochthonous organisms from the Ria de Aveiro (Portugal) area, namely the polychaete Diopatra neapolitana and the bivalve Solen marginatus, to be used in subsequent monitoring studies. In addition, this study also validated the putative use of the now characterized cholinesterasic forms by analyzing the in vitro effects of common anthropogenic contaminants, such as detergents, pesticides, and metals. The predominant cholinesterasic form found in tissues of D. neapolitana was acetylcholinesterase, while homogenates of S. marginatus were shown to possess an atypical cholinesterasic form, with a marked preference for propionylthiocholine. Cholinesterases from D. neapolitana were generally non-responsive towards the majority of the selected chemicals. On the contrary, strong inhibitory effects were reported for ChEs of S. marginatus following exposure to the selected pesticides.

Patient-reported outcome (PRO) data are beneficial to a range of stakeholders including patients, clinicians, researchers, national funding and regulatory agencies, health system administrators, and policymakers. Because stakeholders represent diverse groups and needs, it is challenging to reach consensus on how to advance PRO development and harmonize data across settings to enable use for multiple secondary purposes. Collaborative national networks can facilitate the sharing of expertise, resources, and necessary infrastructure; create development, use, and reporting standards; optimize formats to efficiently store and transfer data; and disseminate tools and information for widespread uptake. In the United States, the National Institutes of Health's Patient-Reported Outcomes Measurement Information System offers an example of how collaborators can work across distances to form essential partnerships, create a common vision, and leverage technology to accelerate the development and testing of universal PROs that are broadly applicable across health conditions and settings.

Terra firma-forme dermatosis: a retrospective review of 31 patients.

PubMed

Berk, David R

2012-01-01

Terra firma-forme dermatosis is an idiopathic condition characterized by acquired, dirtlike plaques despite normal hygiene. A diagnosis can be reached by removing lesions with gentle alcohol swabbing. Although Terra firma-forme dermatosis was first described more than 20 years ago and is thought to be not uncommon in clinical practice, it has never been systematically studied. There are few publications about this condition, including no case series of more than six patients. In particular, little is known about the incidence, peak age groups, and most common locations of Terra firma-forme dermatosis. A retrospective review was conducted to identify cases of Terra firma-forme dermatosis in a single-provider practice consisting of 55% pediatric and 45% adult patients. Thirty-one patients with Terra firma-forme dermatosis were identified, including 10 who presented with Terra firma-forme dermatosis as their primary concern. Only two patients were older than 17 years. The median duration of lesions was 4 months. The most common lesion locations were the neck, ankles, and face. Before presenting to the dermatology clinic, three patients had undergone endocrine evaluations, and four had been prescribed topical corticosteroids. Terra firma-forme dermatosis is relatively common and most often occurs in children on the neck or posterior malleolus. This series exemplifies the importance of recognizing Terra firma-forme dermatosis so as to provide rapid relief for patients and avoid unnecessary tests and treatments. © 2011 Wiley Periodicals, Inc.

Memory for conversation and the development of common ground.

PubMed

McKinley, Geoffrey L; Brown-Schmidt, Sarah; Benjamin, Aaron S

2017-11-01

Efficient conversation is guided by the mutual knowledge, or common ground, that interlocutors form as a conversation progresses. Characterized from the perspective of commonly used measures of memory, efficient conversation should be closely associated with item memory-what was said-and context memory-who said what to whom. However, few studies have explicitly probed memory to evaluate what type of information is maintained following a communicative exchange. The current study examined how item and context memory relate to the development of common ground over the course of a conversation, and how these forms of memory vary as a function of one's role in a conversation as speaker or listener. The process of developing common ground was positively related to both item and context memory. In addition, content that was spoken was remembered better than content that was heard. Our findings illustrate how memory assessments can complement language measures by revealing the impact that basic conversational processes have on memory for what has been discussed. By taking this approach, we show that not only does the process of forming common ground facilitate communication in the present, but it also promotes an enduring record of that event, facilitating conversation into the future.
