Trauma-informed measurement-based care for children: Implementation in diverse treatment settings

Ongoing and comprehensive assessment is a critical part of the implementation of evidence-based care; yet, most providers fail to routinely incorporate measurement into their clinical practice. Few studies have focused on the complex application of routine assessment or measurement-based care (MBC) with children. This pilot examined the acceptability, appropriateness, adoptability, and feasibility of an MBC effort, the Clinical Improvement through Measurement Initiative (CIMI), across several child-serving settings (e.g., community mental health center, residential treatment facility). CIMI includes a comprehensive mental health assessment protocol and combines a mobile technology platform with implementation support. Survey and focus group information, assessing implementation constructs and outcomes, was collected from 44 clinicians and staff. Overall, participants agreed that the implementation process and technology were acceptable, appropriate, and feasible for use in child mental health and that CIMI can be used to guide case conceptualization, facilitate treatment planning, and monitor outcomes. Strategies that supported the implementation process were identified as were recommendations to enhance adoption. Significant differences were observed by Community versus Specialized settings with respect to feasibility and appropriateness, likely because of factors associated with inner setting (climate, compatibility), outer setting (patient needs), and the phase of implementation achieved by sites. Implications and recommendations for tailoring MBC implementation by characteristics related to setting are discussed. MBC across child service settings are discussed in the context of implementation frameworks. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Granulomatous Rhinitis in a Horse due to Mycobacterium intracellulare Infection

Mycobacterial infections in horses are uncommon, but are caused most frequently by Mycobacterium bovis of the Mycobacterium tuberculosis complex or Mycobacterium avium of the M. avium complex. Disease caused by Mycobacterium intracellulare, the second most common species within the M. avium complex, has not been reported in horses to date. Mycobacteriosis in horses most often presents as enteric, pulmonary or, rarely, systemic disease. Here we report a case of M. intracellulare infection in a horse presenting as a granulomatous nasal mass.

Quality of Life of Young Adult Survivors of Pediatric Burns Using World Health Organization Disability Assessment Scale II and Burn Specific Health Scale-Brief: A Comparison

The objective was to determine long-term psychological distress and quality of life (QOL) in young adult survivors of pediatric burns using the World Health Organization Disability Assessment Scale II (WHODAS) and the Burn Specific Health Scale-Brief (BSHS-B). Fifty burn survivors 2.5 to 12.5 years postburn (16-21.5 years old; 56% male, 82% Hispanic) completed the WHODAS and BSHS-B. The WHODAS measures health and disability and the BSHS-B measures psychosocial and physical difficulties. Scores were calculated for each instrument, and then grouped by years postburn, TBSA, sex, burn age, and survey age to compare the effects of each. Next, the instruments were compared with each other. The WHODAS disability score mean was 14.4 ± 2.1. BSHS-B domain scores ranged from 3 to 3.7. In general, as TBSA burned increased, QOL decreased. Female burn survivors, survivors burned prior to school entry, and adolescents who had yet to transition into adulthood reported better QOL than their counterparts. In all domains except Participation, the WHODAS consistently identified more individuals with lower QOL than the BSHS-B. Young adult burn survivors' QOL features more disability than their nonburned counterparts, but score in the upper 25% for QOL on the BSHS-B. This analysis revealed the need for long-term psychosocial intervention for survivors with larger TBSA, males, those burned after school entry, and those transitioning into adulthood. Both instruments are useful tools for assessing burn survivors' QOL and both should be given as they discern different individuals. However, the WHODAS is more sensitive than the BSHS-B in identifying QOL issues.

A high-fat diet supplemented with fish oil improves metabolic features associated with type 2 diabetes

OBJECTIVE

The goal of this study was to investigate the effects of a high-fat diet supplemented with fish oil or olive oil, fed to C57BL/6J mice for an extended period, on metabolic features associated with type 2 diabetes.

METHODS

Mice were fed one of four diets for 30 wk: a low-fat diet, a high-fat diet supplemented with lard, a high-fat diet supplemented with fish oil, or a high-fat diet supplemented with olive oil. Phenotypic and metabolic analysis were determined at 15 and 25 to 30 wk, thereby providing comparative analysis for weight gain, energy consumption, fat distribution, glucose and insulin tolerance, and hepatic/plasma lipid analysis.

RESULTS

Mice fed a high-fat diet supplemented with fish oil had improved glucose tolerance after an extended period compared with mice fed a high-fat diet supplemented with lard. Moreover, mice fed a high-fat diet supplemented with fish oil had significantly decreased concentrations of liver cholesterol, cholesteryl ester, and triacylglycerol compared with mice fed a high-fat diet supplemented with either lard or olive oil.

CONCLUSION

Mice fed a high-fat diet supplemented with fish oil improved metabolic features associated with type 2 diabetes such as impaired glucose tolerance and hepatic steatosis.

The Niemann-Pick C1 gene is downregulated in livers of C57BL/6J mice by dietary fatty acids, but not dietary cholesterol, through feedback inhibition of the SREBP pathway

The Niemann-Pick C1 (NPC1) gene is associated with human obesity. Mouse models with decreased Npc1 gene dosage are susceptible to weight gain when fed a high-fat diet, but not a low-fat diet, consistent with an Npc1 gene-diet interaction. The objectives of this study were to define regulation of the Npc1 gene and to investigate the Npc1 gene-diet interaction responsible for weight gain. The experimental design involved feeding C57BL/6J male mice a low-fat diet (with 0.00, 0.10, or 1.00% cholesterol) or a high-fat diet (with 0.02% cholesterol) until 30 wk to determine regulation of the Npc1 gene in liver. The key results showed that the Npc1 gene was downregulated by dietary fatty acids (54%, P = 0.022), but not by dietary cholesterol, through feedback inhibition of the sterol regulatory element-binding protein (SREBP) pathway. However, the dietary fatty acids secondarily increased liver cholesterol, which also inhibits the SREBP pathway. Similarly, the Npc1 gene was downregulated in peritoneal fibroblasts isolated from C57BL/6J weanling male mice not exposed to the experimental diets and incubated in media supplemented with purified oleic acid (37%, P = 0.038) but not in media supplemented with purified cholesterol. These results are important because they suggest a novel mechanism for the interaction of fatty acids with the Npc1 gene to influence energy balance and to promote weight gain. Moreover, the responsiveness of the Npc1 gene to fatty acids is consistent with studies that suggest that the encoded NPC1 protein has a physiologic role in regulating both cholesterol and fatty acid metabolism.

Multiple processes underlie benzodiazepine-mediated increases in the consumption of accepted and avoided stimuli

Hyperphagia is a reported side effect of anxiolytic benzodiazepines such as chlordiazepoxide (CDP). Prior research has focused primarily on the ingestive responses to sweet or solid foods. We examined CDP effects on licking for normally accepted and avoided taste solutions across a range of concentrations. The effect of CDP (10 mg/kg) versus saline on the licking patterns of water-restricted rats for water and 3 concentrations of sucrose, saccharin, NaCl, monosodium glutamate (MSG), citric acid, and quinine (Q-HCl) solutions was evaluated during 1 h tests. CDP increased meal size for all tastants except citric acid. Analysis of licking microstructure revealed 3 dissociable effects of CDP. CDP affected oromotor coordination as indicated by a uniform increase in the modal interlick interval for all stimuli. CDP increased meal size as indicated by shorter pauses during consumption of water, MSG, and weaker saccharin concentrations, and by fewer long interlick intervals (250-2000 ms) for normally avoided tastants. CDP also increased meal size by increasing burst size, burst duration, and the initial rate of licking for most solutions, suggesting increased hedonic taste evaluation. CDP did not affect variables associated with postingestive feedback such as meal duration or number of bursts, and the results also suggest that CDP did not enhance the perceived taste intensity. We hypothesize that the reduction of pause duration is consistent with an increased motivation to sample the stimulus that synergizes with changes in taste-mediated responsiveness to some but not all stimuli to yield increases in the consumption of both normally accepted and avoided taste stimuli.

Effect of pancreatic and leukocyte elastase on hydraulic conductivity in lung interstitial segments

Elastase-induced changes in flow were used to quantify the degradation of lung interstitial elastin. Degassed rabbit lungs were inflated with silicon rubber via airways and vessels. The lungs were cut into 1-cm-thick sections. Two chambers were bonded to each section to enclose the interstitium surrounding an arterial segment. Flow of albumin solution (0-5 g/dl) between the chambers was followed by that of the albumin solution with 0.25 g/dl pancreatic elastase solution. Driving pressure was 5 cmH(2)0, and mean interstitial pressure was either 0 or 10 cmH(2)O. Elastase caused an increase in flow in approximately 70% of the interstitial segments and a reduction in flow in the remaining segments. The elastase-induced response in flow was independent of both albumin concentration and mean interstitial pressure. Leukocyte elastase (5 units/dl) produced flow responses similar to those of 0.25 g/dl pancreatic elastase. The increased flow of leukocyte elastase was reduced by a subsequent flow with 0.25 g/dl pancreatic elastase but enhanced by a subsequent flow with a 10-fold lower concentration. A change in the order of the elastase flows reversed the concentration-dependent responses. This behavior suggests a complex interaction among the interstitial fibers after degradation by pancreatic and leukocyte elastase. Endogenous elastase-induced increases in interstitial permeability might affect blood-lymph barrier permeability, whereas elastase-induced cessation of flow might be related to the alveolar septal wall destruction observed in emphysema.

Modulation detection interference in cochlear implant subjects

The aim of this study was to determine whether detection thresholds for amplitude modulated signals on a single electrode were influenced by a masking modulation on a second electrode in cochlear implant users. Data were collected from four post-linguistically deafened subjects using the Cochlear Limited prosthesis. Investigated were the effects of the spatial separation between test and masker electrodes, 0 to 5 electrodes (0 to 3.75 mm), and the amount of masking modulation: 24%, 48%, 72%, and 96% above detection thresholds. Initially, modulation detection thresholds for stimulation on a single electrode without masking modulation were obtained for a set of six electrodes in the middle of the array. Modulation detection thresholds on a fixed test electrode were then obtained with unmodulated and modulated masking on a second electrode, which was one of the six electrodes in the initial study. In both studies, thresholds were measured for modulated pulse duration at the modulation frequencies of 10-200 Hz. In the first study, the shape of the detection thresholds as a function of modulation frequency, the temporal modulation transfer function, generally resembled a low-pass filter for two subjects. For the other two subjects, the functions were relatively flat across modulation frequencies. In the second study, unmodulated masking resulted in a small elevation in detection thresholds across electrodes. Modulation detection interference (MDI), the difference between thresholds for the modulated maskers and the unmodulated masker, was greater for larger amounts of masking modulation than for smaller amounts of masking modulation. For three of the four subjects, MDI was higher for smaller spatial separations between the two electrodes than for larger spatial separations suggesting that a portion of MDI may be due to overlap of neural excitation distributions produced by stimulation on two electrodes in close proximity on the array.

Studies of prosody perception by cochlear implant patients

Prosodic information is conveyed to normally-hearing listeners by variations in acoustic fundamental frequency, amplitude envelope, and duration of speech segments. This study measured cochlear implant patients' sensitivity to these parameters in electrically coded speech. The psychophysical discrimination of electric parameters used to code prosodic information, were examined, together with prosody perception using speech processing strategies which modified the contributions of these parameters. Patients were implanted with the Cochlear Limited prosthesis and used the MPEAK speech processing strategy. In the psychophysical studies, difference limens were measured for steady-state and time-varying stimuli, of different pulse rates and pulse durations, over a series of different stimulus durations. These limens were obtained using an adaptive procedure which converged on the 50 per cent correct point. In the prosody perception studies, performance was measured for the MPEAK strategy and for strategies which modified the contributions of pulse rate and pulse duration. Data were collected for five tests of prosodic contrasts. Difference limens for steady-state pulse rates were larger at higher rates (17 per cent at 400 pulses/s) than at lower rates (6 per cent at 100 pulses/s). For some patients, limens for the time-varying pulse rates were larger than those for the steady-state pulse rates while for the other patients, the limens were similar. Difference limens for pulse duration were 0.3 dB, corresponding to 4 per cent of the dynamic range, for steady-state stimuli and doubled in size for the time-varying stimuli. Prosody perception performance was generally poorer for the modified strategies than for the MPEAK strategy, suggesting that the removal of information coded by pulse rate and pulse duration reduced the perception of prosodic contrasts.

Pitch perception for different modes of stimulation using the cochlear multiple-electrode prosthesis

Numerical estimations of pitch were obtained from nine postlinguistically deafened adults using the 22-electrode cochlear implant manufactured by Cochlear Pty. Limited. A series of electrodes on the array were stimulated using three modes of stimulation: Bipolar (BP), common ground (CG), and monopolar (MONO). In BP stimulation, an electric current was passed between two electrodes separated by one electrode for eight patients and two electrodes for one patient. In CG stimulation, a single electrode was activated and the other electrodes on the array were connected together to serve as the return path for the current. In MONO stimulation, an electric current was passed between a single electrode and the most basal electrode on the array. Pitch estimations were generally consistent with the tonotopic organization of the cochlea. There was a marked reversal in pitch for electrodes in the middle of the array using CG stimulation for three patients. A reduced range of pitch using MONO stimulation was recorded for patients where the most basal electrode was internal to the cochlea. There were also individual differences in pitch estimations between the three modes of stimulation for most patients. The current levels required to elicit threshold (T) and comfortable listening (C) levels were, in general, higher for BP stimulation than for CG stimulation and were lowest for MONO stimulation. For CG stimulation, there was a tendency for T and C levels to be higher for electrodes in the middle of the array than at the basal or apical ends. For MONO stimulation, T and C levels uniformly increased in an apical to basal direction for the majority of patients. There was no consistent pattern in T and C levels for BP stimulation. The size of the range of usable hearing using CG stimulation tended to be similar to that using BP stimulation and was usually higher than that using MONO stimulation.

The effects of auditory feedback from the nucleus cochlear implant on the vowel formant frequencies produced by children and adults

Cochlear implants provide an auditory signal with which profoundly deaf users may monitor their own speech production. The vowel production of two adults and three children who used the Nucleus multiple-electrode cochlear implant was examined to assess the effect of altered auditory feedback. Productions of words were recorded under conditions where the talkers received auditory feedback (speech processor turned on) and where no auditory feedback was provided (speech processor turned off). Data were collected over 3 days at weekly intervals. First and second formant frequencies were measured and the data were analysed to assess significant differences between auditory feedback conditions, vowel context, and data collection points. Overall, the results varied across talkers, across the data collection days, and depended on the consonant environment of the vowel. However, two effects of auditory feedback were noted. First, there was a generalized shift in first formant frequencies between the processor on and processor off conditions across three of the five subjects, but the shift differed in direction for each subject. Second, for three of the five talkers, the two front vowels /epsilon/ and /i/ were more neutralised in the absence of auditory feedback. However, this effect was less pronounced than that noted by previous studies.

Immune thrombocytopenias: tests for platelet antibodies

In a study of 49 consecutive patients for whom a test for platelet antibodies had been ordered, tests were performed for both cell-bound and serum platelet antibodies. In cases of autoimmune thrombocytopenia (ITP), the test result for cell-bound antibody was more likely to be positive than was the test result for serum antibody. In three patients with ITP who were taking systemic corticosteroids, however, the result of the CBPAT was negative. A similar phenomenon occurred in a patient with SLE. The result of the SPAT correlated best with the presence of alloantibodies formed during pregnancy or after blood transfusion.

Studies in the childhood psychoses. 3. The family and social background in childhood psychoses

The first paper of this sequence discussed the division of childhood psychoses into those with onset before the age of 3 (infantile psychoses, I.P.) and those with onset after the age of 5 (late onset psychoses, L.O.P.). The second paper described in detail the clinical phenomena in 80 psychotic children so classified at Oxford or Newcastle (see Table I), and showed that this division corresponded to clear-cut distinctions in the clinical pictures. The I.P. group showed gaze avoidance, abnormal pre-occupations, self-isolating patterns of behaviour, echolalia, overactivity. The L.O.P. group showed hallucinations and thought disorder. With these two groups clearly established we now look to see whether anything in their family and background also distinguishes them.
