Lower Recovery

Abstract In previous experiments, the turbidimetric method for determining chlortetracycline-HCI (CTC-HCl) in feeds showed lower recovery than the AOAC plate method. Although the addition of vitamins to the turbidimetric medium improved results, values by the turbidimetric method remained about 10% lower than by the plate method. A modified (1.7 × the weight recommended by the manufacturer) turbidimetric assay medium decreased assay sensitivity but did not significantly change the slope of S. aureus response to CTC-HCl. There was no evidence that vitamin fortification of the modified medium had any significant effect on the growth rate of test organism. Examination of about 100 samples of commercial feeds containing CTC-HCl showed excellent agreement in results between the turbidimetric and plate methods.

Callous Unemotional Traits

AbstractDifferent patterns of emotional reactivity characterize proactive and reactive functions of aggressive behavior, and theory also suggests a link of both types with narcissism. How people with narcissistic traits respond emotionally to competitive scenarios could influence their aggressiveness. Participants were 85 adolescent boys from a detention center. Several indices of emotional functioning were assessed, including attentional bias to negative emotional stimuli and psychophysiological responding. In addition, we included self-report and laboratory measures of aggression and measures of psychopathy-linked narcissism, callous–unemotional traits, and impulsivity. Psychopathy-linked narcissism was uniquely related to unprovoked aggression (i.e., proactive aggression) and to heightened attention to pictures depicting others’ distress. Compared with those scoring low on narcissism, those high on narcissism, who were the least physiologically reactive group, evinced greater proactive aggression, whereas those showing a pattern of coactivation (i.e., sympathetic and parasympathetic autonomic reactivity) evinced greater reactive aggression. Results are consistent with descriptions of narcissistic individuals as being hypervigilant to negative cues and exhibiting poor emotion regulation. These characteristics may lead to aggressive and violent behavior aimed at maintaining dominance over others.

Colonic Manometry

Abstract Background A defecation reflex involves sensory information from the colon sent to the central nervous system which results in propulsive motor patterns in the colon through programmed neural activity from the autonomic nervous system. Neurological causes of constipation are recognized but specific neurological pathways that contribute to pathophysiology of the disease is underexplored. Diagnosis and treatment usually do not involve the autonomic nervous system. Aims Our objective was to assess autonomic dysfunction and abnormal defecation reflexes as a possible cause of chronic constipation. Methods Defecation reflexes were assessed by high-resolution colonic manometry through balloon distention, meal intake, and rectal bisacodyl. Specific heart rate variability (HRV) parameters were used to assess general orthostatic autonomic reactivity, and autonomic functioning during high resolution colonic manometry, in 14 patients with chronic refractory constipation considered for surgery. Results All patients had a unique combination of motility, reflex ability and HRV profiles. Patients overall did not generate HAPWs or had lower HAPW amplitude and lower propulsive activity compared to healthy individuals. Half of the 14 patients were tested to have high sympathetic tone based on Baevsky’s stress index prior to HRCM, and 11 of the patients had sympathetic hyper-reactivity and/or low parasympathetic reactivity to at least one type of colonic stimulation during HRCM. Abnormal autonomic tone or autonomic reactivity to colonic stimulation was present in all four patients with absence of the vagosacral defecation reflex. Five of the seven patients with absence of the sacral defecation reflex showed high sympathetic tone or high sympathetic reactivity to stimulation. Only two patients had abnormality in coloanal coordination and this was associated with low parasympathetic reactivity to stimulation in both patients. Conclusions The assumption that colonic resection was needed to remove an inert colon was wrong in most patients, but most patients had some form of reflex abnormality. Sympathetic dominance far outweighed parasympathetic dysfunction. Incorporation of assessments of defecation reflexes and autonomic nervous system activity into diagnosis of chronic refractory constipation provides a comprehensive pathophysiological understanding of specific defective neurological pathways contributing to dysmotility. This forms the basis for our individualized treatment efforts through sacral neuromodulation. Funding Agencies CIHR
