RESUMEN

PURPOSE: This study explored the feasibility, impact and parent experiences of ENVISAGE (ENabling VISions And Growing Expectations)-Families, a parent-researcher co-designed and co-led program for parents/caregivers raising children with early-onset neurodisabilities. METHODS: Parents/caregivers of a child with a neurodisability aged ≤6 years, recruited in Australia and Canada, participated in five weekly online workshops with other parents. Self-report measures were collected at baseline, immediately after, and 3 months post-ENVISAGE-Families; interviews were done following program completion. Quantitative data were analyzed with generalized estimating equations and qualitative data using interpretive description methodology. RESULTS: Sixty-five parents (86% mothers) were recruited and 60 (92%) completed the program. Strong evidence was found of effects on family empowerment and parent confidence (all p ≤ 0.05 after the program and maintained at 3-month follow-up). The ENVISAGE-Families program was relevant to parents' needs for: information, connection, support, wellbeing, and preparing for the future. Participants experienced opportunities to reflect on and/or validate their perspectives of disability and development, and how these perspectives related to themselves, their children and family, and their service providers. CONCLUSIONS: ENVISAGE was feasible and acceptable for parent/caregivers. The program inspired parents to think, feel and do things differently with their child, family and the people who work with them.Implications for rehabilitationENVISAGE (ENabling VISions And Growing Expectations)-Families is a co-designed, validated parent/researcher "early intervention and orientation" program for caregivers raising a child with neurodevelopmental disabilities (NDDs).ENVISAGE-Families empowered parents' strengths-based approaches to their child, family, disability, and parenting.ENVISAGE-Families increased caregivers' confidence in parenting children with NDD's and provided them tools to support connection, collaboration, and wellbeing.Raising children with NDD can have a profound impact on caregivers, who can benefit from strengths-based, future focused supports early in their parenting experience.

RESUMEN

Walker and Gopnik (2017) suggest they have solved a longstanding problem in comparative and developmental psychology: How to provide an unambiguous measure of analogical reasoning in nonverbal subjects. We argue that this test, much like many others that purport to measure analogical reasoning in nonverbal subjects, does not distinguish between the two competing accounts of successful performance: the use of perceptual variance among stimuli to support higher-order concepts like "same" and "different" versus use of perceptual variance alone.

RESUMEN

In accidents resulting in severe injuries, a clinical forensic examination is generally abandoned in the initial phase due to high-priority clinical needs. However, in many cases, data from clinical computed tomography (CT) examinations are available. The goals of this prospective study were (a) to evaluate clinical CT data as a basis for forensic reconstruction of the sequence of events, (b) to assess if forensic radiological follow-up reading improves the forensic diagnostic benefit compared to the written clinical radiological reports, and (c) to evaluate if full data storage including additional reconstructed 0.6-mm slices enhances forensic analysis. Clinical CT data of 15 living individuals with imaging of at least the head, thorax, and abdomen following polytrauma were examined regarding the forensic evaluation of the sequence of events. Additionally, 0.6-mm slices and 3D images were reconstructed for forensic purposes and used for the evaluation. At the forensic radiological readings, additional traumatic findings were observed in ten of the 15 patients. The main weakness of the clinical reports was that they were not detailed enough, particularly regarding the localization of injuries and description of wound morphology. In seven cases, however, forensic conclusions were possible on the basis of the written clinical reports, whereas in five cases forensic reconstruction required specific follow-up reading. The additional 0.6-mm slices were easily available and with improved 3D image quality and forensic diagnostics. In conclusion, the use of clinical CT data can considerably support forensic expertise regarding reconstruction issues. Forensic follow-up reading as well as the use of additional thin slices for 3D analysis can further improve its benefit for forensic reconstruction purposes.

RESUMEN

Infections with orthopoxviruses usually lead to cross-protection among all species of the family. This has been a prerequisite for successful eradication of smallpox. Here we report the rare case of a 17-year-old male, who survived a generalised cowpox virus infection of unusual severity but surprisingly did not show a proper seroconversion. Only a very weak antibody production was observed in early and late serum samples, which initially appeared to be cowpox virus specific in immunofluorescence. No neutralising antibodies were detected and in Western blotting antibody specificity was restricted to the orthopoxvirus H3L protein only. The patient had been hospitalised for alcohol and cannabis intoxication 2 months prior to the orthopoxvirus infection and high levels of cannabinoids have been found repeatedly in the urine and upon one occasion also benzodiazepines. As these substances are known to interfere with antibody production and no immunodeficiencies were detected, drug-induced immunosuppression can be suspected as the most likely cause. Therefore a possible link between "soft" drug use and sufficient immunosuppression to warrant alterations in vaccine policies using live virus vaccines like smallpox vaccine should be further studied.

RESUMEN

In a case-control study that included a total of 98 patients and 83 controls, the possible link between various pathogens and abdominal aortic aneurysms was investigated. For 68 patients with abdominal aortic aneurysm and age-matched controls, no differences were detected in the levels of immunoglobulin (Ig)A and IgG Chlamydiaceae and Chlamydophila pneumoniae antibodies. Patients with IgA titers positive for Chlamydophila pneumoniae showed progressive disease (defined as an annual increase of the aneurysm diameter of > or = 0.5 cm) more frequently than patients with negative IgA titers (p = 0.046). Polymerase chain reactions performed to detect DNA for Chlamydophila pneumoniae, Chlamydia trachomatis, Chlamydophila psittaci, human cytomegalovirus, Borrelia burgdorferi and Helicobacter pylori in tissue specimens of 30 patients and 15 controls were negative. In summary, Chlamydophila pneumoniae may contribute to aortic aneurysm disease progression, but DNA of this and other pathogens was not found in patients' specimens.

RESUMEN

We investigated 15 polymorphic short tandem repeat (STR) loci (D1S1656, D7S1517, D8S306, D8S639, D9S304, D10S2325, D11S488, D12S391, D14S608, D16S3253, D17S976, D18S1270, D19S253, D20S161, and D21S1437) which are not included in the standard sets of forensic loci. The markers were selected according to the complexity of the polymorphic region: Of the 15 investigated loci, 7 loci showed a simple repeat structure (D9S304, D10S2325, D14S608, D16S3253, D18S1270, D19S253, and D21S1437), 3 loci (D7S1517, D12S391, and D20S161) consisted of compound repeat units, and 5 loci (D1S1656, D8S306, D8S639, D11S488, and D17S976) showed a more complex polymorphic region partly including different repeat blocks and incomplete repeat units, which resulted in a relatively high proportion of intermediate alleles. A population study on a sample of 270 unrelated persons from Austria was carried out. We did not observe significant deviations from Hardy-Weinberg expectations. The combined probability of exclusion for the 15 loci was 0.99999998. In combination with the conventional set of STR markers included in commercially available kits (no linkage was observed between these 15 loci and the Powerplex 16 System loci), these markers are approved as highly discriminating forensic tools, also suitable for the analysis of difficult paternity and kinship constellations.

RESUMEN

The conversion factor Q, obtained by division of blood alcohol concentration (BAC) by breath alcohol concentration (BrAC) is a widely discussed topic due to its great variance. By Austrian law, regulations frequently require an estimation of a corresponding BAC by a measured BrAC. It is known that Q depends among other things, on the alcohol kinetic state of the person being tested, which mathematically can be transformed to a dependency on the BrAC. Theoretically calculated Q values per BrAC level form a hyperbola shaped curve, thus decreasing with increasing BrAC values. Applying Austrian forensic standards for BAC and BrAC measurements, these calculations were verified in a study under practical conditions with BAC and BrAC data of 390 individuals. Q decreases from 2629 (+/- 455) for BrAC levels < 0.1 mg/l to 2229 (+/- 160) for a BrAC range of 0.4-0.5 mg/l and increases again to 2428 (+/- 124) for BrAC levels > 0.6 mg/l. Since these results were obtained under realistic practical conditions they can be directly applied in routine forensic expert opinion and can eliminate avoidable variances in the calculation of Q.

RESUMEN

A multiplex PCR was designed for the loci D2S1338, D16S539, D18S51, TH01 and FGA using redesigned primers in order to reduce the lengths of the amplification products compared to the designs used in commercially available multiplex PCR kits, also including amelogenin. The new PCR primers were used to amplify highly degraded DNA from casework samples, which had shown no or only poor results for these loci in previous analyses with standard primer sets. The application of the new miniSTR-multiplex resulted in an increased overall typing success rate for degraded DNA samples. In a concordance study between the conventional and the newly designed primers, no genotype differences were revealed in 124 randomly selected individuals.

RESUMEN

When testing the Microgenics CEDIA assay for immunological buprenorphine analysis, cross-reactivity between the buprenorphine reagents and opiates was observed at concentrations higher than 120 mg/l morphine, 320 mg/l methadone, 30 mg/l codeine, 60 mg/l dihydrocodeine and 520 mg/l morphine-3-glucuronide. The cross-reactivity with morphine has the greatest impact on routine screening as opiate maintenance therapy in Austria is also performed with slow-release oral morphine. The use of a second cutoff value of 30 mug/l for urine samples that are (immunologically) positive for opiates is therefore suggested, compared to the cutoff value of 5 microg/l proposed by the manufacturer.

RESUMEN

Unusually large variant alleles were observed in the short tandem repeat (STR) systems D3S1358 and D21S11, both of which are included in the international standard set of loci (ISSOL) and routinely typed in National DNA intelligence databases worldwide. The observed alleles fell within the size range of the adjacent STR marker, which could easily cause problems with respect to correct allele assignments for both loci concerned. We compared the amplification and potential interpretation with three different commercially available kits, which are frequently used in forensic work. PCR products were cloned and sequenced in order to determine the structure of these unusual allele variants and confirm their size and designation (D3S1358 allele 26, D21S11 allele 46). In the locus D21S11 we observed an as yet undescribed partial duplication of the constant region.

RESUMEN

Resuscitation of patients in hemorrhagic shock remains one of the most challenging aspects of trauma care. We showed in experimental studies that vasopressin, but not fluid resuscitation, enabled short-term and long-term survival in a porcine model of uncontrolled hemorrhagic shock after penetrating liver trauma. In this case report, we present two cases with temporarily successful cardiopulmonary resuscitation (CPR) using vasopressin and catecholamines in uncontrolled hemorrhagic shock with subsequent cardiac arrest that was refractory to catecholamines and fluid replacement. In a third patient, an infusion of vasopressin was started before cardiac arrest occurred; in this case, we were able to stabilize blood pressure thus allowing further therapy. The patient underwent multiple surgical procedures, developed multi-organ failure, but was finally discharged from the critical care unit without neurological damage.

RESUMEN

A total of 34 deployed driver and passenger airbags from altogether 20 vehicles after frontal collisions were investigated. In 80% of the airbags possible biological traces could be located with an alternative light source (ALS, Polilight) at a wavelength of 450-470 nm. These traces were swabbed, a part of them additionally cut and subjected to DNA analysis, which led to comparable SGMplus profiles in about 60%. In the 20% of the airbags on which no possible biological traces could be located, the whole surfaces were swabbed. In these cases subsequent DNA profiling mostly led to non-interpretable results. For the evaluation and interpretation of the data, buccal swab samples provided by drivers and co-drivers were analysed. The results and conclusions from DNA analyses and the declarations from the involved passengers were always concordant. Thus, molecular biological analysis of deployed airbags can help to determine the occupants positions within a vehicle (driver or passenger status) at the time of impact.

RESUMEN

A 47-year-old male patient died unexpectedly 10 years after replacement of the aortic valve with a Carbomedics heart valve prosthesis required for post-endocarditic valve stenosis. The man was in regular medical attendance by his general practitioner and in hospital. Clinical data and examinations did not suggest the reoccurrence of endocarditis. Three months before his death a haemolytic anaemia of unknown genesis was diagnosed. One afternoon, while lifting a heavy object, the man suffered acute chest pain and collapsed. Resuscitation failed and the patient died in hospital. Autopsy revealed the completely detached valve prosthesis within the ascending aorta. Histological examination confirmed a chronic endocarditis at the site of the valve implantation.

RESUMEN

A case of suicide with the insecticide omethoate is reported. An 18-year-old apprentice gardener had ingested an unknown amount of omethoate. His body was found in his room lying in the storage space under his bed. The autopsy first showed multiple superficial incisions in the skin of his wrists, furthermore hemorrhagic pulmonary oedema, dilation of the right cardiac ventricle and oedema of the brain. The gastric mucosa was swollen and showed a dark brownish colour. An intensive, chemical-like smell rose from the corpse and organs. Toxicological analysis detected omethoate in cardiac blood (208 micro g/ml), urine (225 micro g/ml) and bile (524 micro g/ml), in the liver (341 micro g/ml) and kidneys (505 micro g/ml). In the gastric content the level was 48223 micro g/ml. The amount of the active AChE in peripheral blood serum was reduced to less than 0.2% of the normal level. To our knowledge no case of a fatal suicide by ingestion of omethoate has been reported in literature.

RESUMEN

A fatal accident after isoflurane abuse is presented in this report. A hospital employee was found dead in the operating area with a plastic bag over his head. In his locker an almost empty bottle of isoflurane was found. Autopsy revealed signs of asphyxiation and toxicological examination revealed nordazepam and isoflurane in non-toxic concentrations in the blood. Quantification of the anaesthetic was also carried out in urine, gastric contents, liver, kidney and brain samples, and in addition, oxazepam, prothipendyl and metabolites of midazolam and prothipendyl were found in the urine. Although the drug problems of the deceased were known before, no efforts had been made to restrict access to these drugs.

RESUMEN

Repeat measurements of patient characteristics are often used to assess response to treatment. In this paper we discuss a normal mixture model for the observed change in the characteristic of interest in treated patients. The methods described can be used to estimate the overall proportion of non-response to treatment and also the probability that a patient has not responded to treatment given his or her observed change. The model parameters are estimated using maximum likelihood, and the delta method is used to construct a pointwise confidence band for the conditional probability that a patient is a non-responder to treatment. The work was initially motivated by analysis issues in the Fracture Intervention Trial (FIT), a randomized trial of the osteoporosis drug alendronate, and the method is illustrated with data from that study. We also evaluate key aspects of the estimation procedure with two simulation studies. In the first, the data generation model is the assumed normal mixture model, and in the second, the data are generated according to a shifted and scaled central t-distribution model suggested by the FIT data.

RESUMEN

An important assumption for DNA fingerprinting of Mycobacterium tuberculosis is that patients are infected with only one strain at a time. Nonetheless, we demonstrate a case of simultaneous infection with two drug-susceptible strains of M. tuberculosis in an immunocompetent patient by IS6110 restriction fragment length polymorphism and spoligotyping. Epidemiological data prove the patient's involvement in two independent clusters. Thus, double infections should be suspected with fingerprints showing divergent band intensities.

RESUMEN

The mechanism of the interaction of eserine with butyrylcholinesterase has been proposed only on the basis of analogy with acetylcholinesterase. Here the interactions was studied in detail and the results analysed by classical kinetic methods and by means of mathematical modelling. An appropriate kinetic scheme was developed, an adequate equation derived and the corresponding kinetic parameters evaluated. The findings suggest that a fast but relatively weak binding of eserine to the enzyme's active site is followed by a slow acylation step and by an even slower rate limiting deacylation step so misrepresenting eserine as an irreversible inhibitor. The proposed kinetic scheme also suggests that the reaction of eserine with a peripheral substrate site is unlikely as seen with the substrate, butyrylthiocholine.
