Hospital-onset clostridium difficile infection rates in persons with cancer or Hematopoietic stem cell transplant: A C3IC network report

A multicenter survey of 11 cancer centers was performed to determine the rate of hospital-onset Clostridium difficile infection (HO-CDI) and surveillance practices. Pooled rates of HO-CDI in patients with cancer were twice the rates reported for all US patients (15.8 vs 7.4 per 10,000 patient-days). Rates were elevated regardless of diagnostic test used

Population Analysis of the Fusarium graminearum Species Complex from Wheat in China Show a Shift to More Aggressive Isolates

A large number of Fusarium isolates was collected from blighted wheat spikes originating from 175 sampling sites, covering 15 provinces in China. Species and trichothecene chemotype determination by multilocus genotyping (MLGT) indicated that F. graminearum s. str. with the 15-acetyl deoxynivalenol (15ADON) chemotype and F. asiaticum with either the nivalenol (NIV) or the 3-acetyl deoxynivalenol (3ADON) chemotype were the dominant causal agents. Bayesian model-based clustering with allele data obtained with 12 variable number of tandem repeats (VNTR) markers, detected three genetic clusters that also show distinct chemotypes. High levels of population genetic differentiation and low levels of effective number of migrants were observed between these three clusters. Additional genotypic analyses revealed that F. graminearum s. str. and F. asiaticum are sympatric. In addition, composition analysis of these clusters indicated a biased gene flow from 3ADON to NIV producers in F. asiaticum. In phenotypic analyses, F. asiaticum that produce 3ADON revealed significant advantages over F. asiaticum that produce NIV in pathogenicity, growth rate, fecundity, conidial length, trichothecene accumulation and resistance to benzimidazole. These results suggest that natural selection drives the spread of a more vigorous, more toxigenic pathogen population which also shows higher levels of fungicide resistance

The contribution of embarrassment to phobic dental anxiety: a qualitative research study

BACKGROUND: Embarrassment is emphasized, yet scantily described as a factor in extreme dental anxiety or phobia. Present study aimed to describe details of social aspects of anxiety in dental situations, especially focusing on embarrassment phenomena. METHODS: Subjects (Ss) were consecutive specialist clinic patients, 16 men, 14 women, 20–65 yr, who avoided treatment mean 12.7 yr due to anxiety. Electronic patient records and transcribed initial assessment and exit interviews were analyzed using QSR"N4" software to aid in exploring contexts related to social aspects of dental anxiety and embarrassment phenomena. Qualitative findings were co-validated with tests of association between embarrassment intensity ratings, years of treatment avoidance, and mouth-hiding behavioral ratings. RESULTS: Embarrassment was a complaint in all but three cases. Chief complaints in the sample: 30% had fear of pain; 47% cited powerlessness in relation to dental social situations, some specific to embarrassment and 23% named co-morbid psychosocial dysfunction due to effects of sexual abuse, general anxiety, gagging, fainting or panic attacks. Intense embarrassment was manifested in both clinical and non-clinical situations due to poor dental status or perceived neglect, often (n = 9) with fear of negative social evaluation as chief complaint. These nine cases were qualitatively different from other cases with chief complaints of social powerlessness associated with conditioned distrust of dentists and their negative behaviors. The majority of embarrassed Ss to some degree inhibited smiling/laughing by hiding with lips, hands or changed head position. Secrecy, taboo-thinking, and mouth-hiding were associated with intense embarrassment. Especially after many years of avoidance, embarrassment phenomena lead to feelings of self-punishment, poor self-image/esteem and in some cases personality changes in a vicious circle of anxiety and avoidance. Embarrassment intensity ratings were positively correlated with years of avoidance and degree of mouth-hiding behaviors. CONCLUSIONS: Embarrassment is a complex dental anxiety manifestation with qualitative differences by complaint characteristics and perceived intensity. Some cases exhibited manifestations similar to psychiatric criteria for social anxiety disorder as chief complaint, while most manifested embarrassment as a side effect
