Data has been presented in support of the prophylactic utilization of a comprehensive therapeutic program for patients with cystic fibrosis. Ninety-eight consecutive patients have been followed for 3 to 7 years (average 4½ years). The course of the disease as shown by the clinical evaluations of General Activity, Physical Examination of the Chest, Nutrition, and Chest X-ray for the 49 of these patients considered to be on prophylactic therapy has been significantly different from the accepted natural course of the disease and from that of the 49 patients who had irreversible pulmonary damage when first seen. Objective data collected on these patients including growth and weight changes, morbidity and mortality experience, and pulmonary function studies showed good correlation with the clinical evaluations. No evidence of significant progression in the pulmonary lesion was observed by any criteria for the prophylactically treated group. Indeed, mean pulmonary function test results for these patients were well within the range of normal values even at the end of the average 4½-year follow-up period at an average age of 7 years. No deaths occurred in this group. The mortality rate of only 2% per year of follow-up, with no deaths under 6 years of age, for the entire group of 98 patients indicates the over-all effectiveness of the therapeutic program. This study supports the need for early diagnosis and the prophylactic approach to treatment.

The effect of radiotherapy on the pulmonary damage caused by paraquat (24% solution of 1,1'dimethyl-4,4'-bipyridylium dichloride) was investigated in a preliminary series of nine patients. Paraquat intoxication was diagnosed by quantitative analysis of urine and plasma using colorimetry after extraction of a cation exchange column. The irradiation was given as a planned procedure from day 2 in cases 1 to 7, and after changes in chest X-ray were recognized in cases 8 and 9. A cobalt-60 unit with opposed anterior and posterior portals was used to give a total dose of 12.50 Gy (uncorrected) over 10 fractions, sparing the pericardium and mediastinum as much as possible. Each fraction consisted of 1.25 Gy (125 rad) given once a day, alternating between the left and right lungs. Radiological diagnosis consisted of clear chest X-rays (cases 2 to 4), pulmonary oedema (cases 7 and 9) and interstitial infiltrates (cases 1, 5, 6 and 8). Cases 1, 5, and 8 survived. Case 8 had residual interstitial infiltrates three months after ingestion but these had cleared one month later, suggesting that the diagnosis of irreversible fibrosis should only be made after a follow-up period of at least one year. The results have failed to show a definite benefit, but do support the fact that radiotherapy should be assessed carefully in a randomized trial which is now in progress.

AbstractNeurobiology-based interventions for mental diseases and searches for useful biomarkers of treatment response have largely failed. Clinical trials should assess interventions related to environmental and social stressors, with long-term follow-up; social rather than biological endpoints; personalized outcomes; and suitable cluster, adaptive, and n-of-1 designs. Labor, education, financial, and other social/political decisions should be evaluated for their impacts on mental disease.

AbstractA long-term photographic search programme for minor planets was begun at the Kleť Observatory at the end of seventies using a 0.63-m Maksutov telescope, but with insufficient respect for long-arc follow-up astrometry. More than two thousand provisional designations were given to new Kleť discoveries. Since 1993 targeted follow-up astrometry of Kleť candidates has been performed with a 0.57-m reflector equipped with a CCD camera, and reliable orbits for many previous Kleť discoveries have been determined. The photographic programme results in more than 350 numbered minor planets credited to Kleť, one of the world's most prolific discovery sites. Nearly 50 per cent of them were numbered as a consequence of CCD follow-up observations since 1994.This brief summary describes the results of this Kleť photographic minor planet survey between 1977 and 1996. The majority of the Kleť photographic discoveries are main belt asteroids, but two Amor type asteroids and one Trojan have been found.

During a project in which regenerative changes were studied in autotransplanted canine kidneys, intranuclear crystals were seen in a small number of tubular epithelial cells. These crystalline structures were seen in the control specimens and also in regenerating specimens; the main differences being in size and number of them. The control specimens showed a few tubular epithelial cell nuclei almost completely occupied by large crystals that were not membrane bound. Subsequent follow-up biopsies of the same kidneys contained similar intranuclear crystals but of a much smaller size. Some of these nuclei contained several small crystals. The small crystals occurred at one week following transplantation and were seen even four weeks following transplantation. As time passed, the small crystals appeared to fuse to form larger crystals.

Scanning microscopy was used to study the surface of human gallstones and the surface of fractures. The specimens were obtained by operation, washed with water, dried at room temperature and shadowcasted with carbon and aluminum. Most of the specimens belong to patients from a series of X-ray follow-up study, examined during the last twenty years. So it was possible to evaluate approximately the age of these gallstones and to get information on the intensity of growing and solving.Cholesterol, a group of bile pigment substances and different salts of calcium, are the main components of human gallstones. By X-ray diffraction technique, infra-red spectroscopy and by chemical analysis it was demonstrated that all three components can be found in any gallstone. In the presence of water cholesterol crystallizes in pane-like plates of the triclinic crystal system.

A modification of the Paired-Stimuli Parent Program (Florance, 1977) was adapted for the treatment of articulatory errors of visually handicapped children. Blind high school students served as clinical aides. A discussion of treatment methodology, and the results of administrating the program to 32 children, including a two-year follow-up evaluation to measure permanence of behavior change, is presented.

Purpose The current investigation is a follow-up from a previous study examining child language diagnostic decision making in school-based speech-language pathologists (SLPs). The purpose of this study was to examine the SLPs' perspectives regarding the use of evidence-based practice (EBP) in their clinical work. Method Semistructured phone interviews were conducted with 25 school-based SLPs who previously participated in an earlier study by Fulcher-Rood et al. 2018). SLPs were asked questions regarding their definition of EBP, the value of research evidence, contexts in which they implement scientific literature in clinical practice, and the barriers to implementing EBP. Results SLPs' definitions of EBP differed from current definitions, in that SLPs only included the use of research findings. SLPs seem to discuss EBP as it relates to treatment and not assessment. Reported barriers to EBP implementation were insufficient time, limited funding, and restrictions from their employment setting. SLPs found it difficult to translate research findings to clinical practice. SLPs implemented external research evidence when they did not have enough clinical expertise regarding a specific client or when they needed scientific evidence to support a strategy they used. Conclusions SLPs appear to use EBP for specific reasons and not for every clinical decision they make. In addition, SLPs rely on EBP for treatment decisions and not for assessment decisions. Educational systems potentially present other challenges that need to be considered for EBP implementation. Considerations for implementation science and the research-to-practice gap are discussed.

Purpose A significant relationship between verbal short-term memory (STM) and language performance in people with aphasia has been found across studies. However, very few studies have examined the predictive value of verbal STM in treatment outcomes. This study aims to determine if verbal STM can be used as a predictor of treatment success. Method Retrospective data from 25 people with aphasia in a larger randomized controlled trial of phonomotor treatment were analyzed. Digit and word spans from immediately pretreatment were run in multiple linear regression models to determine whether they predict magnitude of change from pre- to posttreatment and follow-up naming accuracy. Pretreatment, immediately posttreatment, and 3 months posttreatment digit and word span scores were compared to determine if they changed following a novel treatment approach. Results Verbal STM, as measured by digit and word spans, did not predict magnitude of change in naming accuracy from pre- to posttreatment nor from pretreatment to 3 months posttreatment. Furthermore, digit and word spans did not change from pre- to posttreatment or from pretreatment to 3 months posttreatment in the overall analysis. A post hoc analysis revealed that only the less impaired group showed significant changes in word span scores from pretreatment to 3 months posttreatment. Discussion The results suggest that digit and word spans do not predict treatment gains. In a less severe subsample of participants, digit and word span scores can change following phonomotor treatment; however, the overall results suggest that span scores may not change significantly. The implications of these findings are discussed within the broader purview of theoretical and empirical associations between aphasic language and verbal STM processing.

Purpose This study investigated the extent to which speech-language pathologists (SLPs) facilitate parents' completion of homework activities for children with speech sound disorder (SSD). In addition, this study explored factors related to more consistent communication about homework completion and strategies considered particularly effective for supporting this element of parental involvement. Method Licensed SLPs serving at least one child with SSD were invited to participate in an online survey. Questions relevant to this study gathered information regarding (a) frequency of communication about homework distribution and follow-up, (b) demographic and workplace characteristics, and (c) an open-ended question about the specific strategies used to support parental involvement and completion of homework activities. Results Descriptive results indicated considerable variability with respect to how frequently SLPs engaged in communication about homework completion, but that school-based SLPs were significantly less likely to engage in this type of follow-up. Strategies considered effective, however, were similar across therapy contexts. Conclusion These results suggest potentially important differences between school-based services and therapy in other contexts with respect to this particular aspect of service provision for children with SSD.
