TL;DR: It is possible that changes in evoked potential measurementss may be useful as a neurophysiological indicator of anaesthetic depth.
Abstract: Somatosensory, visual and brainstem auditory evoked potentials were recorded in 10 unpremedicated patients anaesthetized with isoflurane in oxygen. Recordings were made at 0.5%, 1.1% and 1.65% (six patients) end-tidal isoflurane concentration. There were statistically significant increases in the latencies of the somatosensory (N20), visual and brainstem auditory potentials (waves III and V) with increasing concentrations of isoflurane. The central conduction time was prolonged. Amplitudes of the somatosensory and visual potentials were reduced with increasing concentrations of isoflurane. The effects of isoflurane on evoked potentials are similar to those of halothane and enflurane. It is possible that changes in evoked potential measurements may be useful as a neurophysiological indicator of anaesthetic depth.

TL;DR: It is concluded that neonates with high resistance patterns of blood flow velocity in the superior mesenteric artery on the first day of life are at increased risk of developing necrotizing enterocolitis.
Abstract: Objective The purpose of this work was to relate Doppler indices of splanchnic perfusion and vascular resistance to the risk of developing necrotizing enterocolitis. Methods We conducted a prospective cohort study with analysis of Doppler flow velocity waveforms of splanchnic vessels on the first day of life. Clinical management and diagnosis of necrotizing enterocolitis were performed blind to the Doppler results in a tertiary NICU on 64 eligible preterm neonates admitted for intensive care. We measured necrotizing enterocolitis using an objective diagnostic classification. Results When adjusted for gestational age at birth, the following indices of the Doppler flow velocity wave form in the superior mesenteric artery were significantly predictive of the risk of necrotizing enterocolitis: end-diastolic velocity, mean velocity, and pulsatility index. The association between necrotizing enterocolitis and Doppler velocimetry indicative of high vascular resistance was independent of a range of other factors and comorbidities (race, mode of delivery, umbilical arterial catheter, growth restriction, patent ductus arteriosus, jaundice, respiratory distress syndrome, mechanical ventilation, and hypotension). Conclusions We concluded that neonates with high resistance patterns of blood flow velocity in the superior mesenteric artery on the first day of life are at increased risk of developing necrotizing enterocolitis.

TL;DR: In one of two XX males with psychosis, the breakpoint on the Y is located within the distal region of homology to the block in Xq21, consistent with the hypothesis that an X-Y homologous determinant of cerebral asymmetry carries the variation that contributes to the predisposition to psychotic illness.
Abstract: The hypothesis that psychosis arises as a part of the genetic diversity associated with the evolution of language generates the prediction that illness will be linked to a gene determining cerebral asymmetry, which, from the evidence of sex chromosome aneuploidies, is present in homologous form on the X and Y chromosomes. We investigated evidence of linkage to markers on the X chromosome in 1) 178 families multiply affected with schizophrenia or schizoaffective disorder with a series of 16 markers spanning the centromere (study 1), and 2) 180 pairs of left-handed brothers with 14 markers spanning the whole chromosome (study 2). In study 1, excess allele-sharing was observed in brother-brother pairs (but not brother-sister or a small sample of sister-sister pairs) over a region of approximately 20 cM, with a maximum LOD score of 1.5 at DXS991. In study 2, an association between allele-sharing and degree of left-handedness was observed extending over approximately 60 cM, with a maximum lod score of 2.8 at DXS990 (approximately 20 cM from DXS991). Within the overlap of allele-sharing is located a block in Xq21 that transposed to the Y chromosome in recent hominid evolution and is now represented as two segments on Yp. In one of two XX males with psychosis we found that the breakpoint on the Y is located within the distal region of homology to the block in Xq21. These findings are consistent with the hypothesis that an X-Y homologous determinant of cerebral asymmetry carries the variation that contributes to the predisposition to psychotic illness.

TL;DR: Treatment options are very limited for individuals with schizophrenia resistant to clozapine and the hypothesis that amisulpride augmentation would lead to an improvement in patients is tested.
Abstract: Objective: Treatment options are very limited for individuals with schizophrenia resistant to clozapine. We tested the hypothesis that amisulpride augmentation would lead to an improvement in these patients.
Method: This was an open non-randomized study. Thirty-three patients with sub-optimal response to clozapine were commenced on amisulpride in addition to clozapine. Clinical status was evaluated at baseline, 3 and 6 months using the Positive And Negative Syndrome Scale (PANSS), Scale for the Assessment of Negative Symptoms (SANS), Global Assessment Scale (GAS), Calgary Depression Scale, Calgary Anxiety Scale and various side effect rating scales.
Results: Twenty-eight subjects completed 6 months treatment on clozapine and amisulpride. There was a statistically significant improvement in the mean scores for PANSS, SANS and GAS at follow-up and no significant changes in side effect ratings.
Conclusion: Co-administration of amisulpride, in a group of patients partially or non-responsive to clozapine, may lead to a substantial improvement in positive and negative symptoms, without worsening the side effect burden.
