The aim of the present study was to examine whether infants would accept an oral motor pacifier (OMP).
Sixteen infants were examined for their immediate acceptance of an OMP. The pacifier was regarded as accepted, if the child took it in the mouth and kept it there actively, i.e. sucked it in one way or other. Their parents were informed verbally and in writing literally about how to offer the OMP to the child and how to use it. The OMP was presented to the child and the child permitted to insert it into her/his mouth by her/himself or if the child failed to do so, the OMP was gently put to the child's mouth. The subjects' reactions were structurally evaluated in terms of 11 statements. The parents of the children received a structured questionnaire with a space for optional free comments and personal opinions.
The median age (6 females, 10 males) was 18 months (mean 19.2 months, s.d. 10.6 and range 2-38 months). The statement scores showed no significant differentiation based on the age of the subject. The parents' reports indicated that 14 (87.5%) of the 18 subjects accepted the OMP, 13 (81.3%) enjoyed watching the pacifier as it was shown to them, and 11 (68.8%) explored it with their fingers while holding it in their hands.
The vast majority of the children accepted the new OMP either at the first trial or after a few trials.
People of South-Asian origin have an increased prevalence of coronary artery disease. Although cardiac rehabilitation (CR) is effective, South Asians are among the least likely people to participate in these programs. Automatic referral increases CR use and may reduce access inequalities. This study qualitatively explored whether CR referral knowledge and access varied among South-Asian patients. Participants were South-Asian cardiac patients receiving treatment at hospitals in Ontario, Canada. Each hospital refers to CR via one offour methods: automatically through paper or electronically, through discussion with allied health professionals (liaison referral), or through referral at the physician's discretion. Data were collected via interviews and analyzed using interpretive-descriptive analysis. Four themes emerged: the importance of predischarge CR discussions with healthcare providers, limited knowledge of CR, ease of the referral process for facilitators of CR attendance, and participants'needs for personal autonomy regarding their decision to attend CR. Liaison referral was perceived to be the most suitable referral method for participants. It facilitated communication between patients and providers, ensuring improved understanding of CR. Automatic referral may not be as well suited to this population because of reduced patient-provider communication.
To propose and evaluate a novel nonrigid image registration approach for improved myocardial T1 mapping.
Myocardial motion is estimated as global affine motion refined by a novel local nonrigid motion estimation algorithm. A variational framework is proposed, which simultaneously estimates motion field and intensity variations, and uses an additional regularization term to constrain the deformation field using automatic feature tracking. The method was evaluated in 29 patients by measuring the DICE similarity coefficient and the myocardial boundary error in short axis and four chamber data. Each image series was visually assessed as "no motion" or "with motion." Overall T1 map quality and motion artifacts were assessed in the 85 T1 maps acquired in short axis view using a 4-point scale (1-nondiagnostic/severe motion artifact, 4-excellent/no motion artifact).
Increased DICE similarity coefficient (0.78 ± 0.14 to 0.87 ± 0.03, P
The hygiene hypothesis stipulates that microbial exposure during early life induces immunologic tolerance via immune stimulation, and hence reduces the risk of allergy development. Several common lifestyle factors and household practices, such as dishwashing methods, may increase microbial exposure. The aim of this study was to investigate if such lifestyle factors are associated with allergy prevalence.
Questionnaire-based study of 1029 children aged 7 to 8 years from Kiruna, in the north of Sweden, and Mölndal, in the Gothenburg area on the southwest coast of Sweden. Questions on asthma, eczema, and rhinoconjunctivitis were taken from the International Study of Asthma and Allergies in Childhood questionnaire.
Hand dishwashing was associated with a reduced risk of allergic disease development (multivariate analysis, odds ratio 0.57; 95% confidence interval: 0.37-0.85). The risk was further reduced in a dose-response pattern if the children were also served fermented food and if the family bought food directly from farms.
In families who use hand dishwashing, allergic diseases in children are less common than in children from families who use machine dishwashing. We speculate that a less-efficient dishwashing method may induce tolerance via increased microbial exposure.
Time-study techniques were used at several chemical enterprises to assess 13 basic elements of the operator's labour, and to determine their average energy inputs in the conditions of a modern chemical plant. A table was drawn up as a time-study guidance for establishing energy inputs in a unit of time, thus determining the labour intensity degree. The contributors set forth a hypothesis regarding the influence of chemical processing products on the non-direct calorimetry indices in energy input analyses. It was further shown that, with the workers contacts with chemical substances in the concentrations peculiar of a modern chemical plant, no correlation corresponding to the chemical factors was required.
The object of the investigation reported in this paper was to study, from the point of view of statistical and geometric theory of pattern recognition, the DNA optical density distribution peculiarities in the interphase nuclei of buccal epithelium present in the pathology of the thyroid and mammary glands. Two new indices to characterize this distribution (ratio of modal class volumes and relief index) are proposed. It is shown that in malignant neoplasms of the thyroid and mammary glands the changes in the nuclei of buccal epithelium are characterized by an increase in the optical density of DNA over a range from 0.15 to 0.30 in conventional units of measure, as compared with its values in benign pathological processes. The sensitivity of the proposed criterion for diseases of the thyroid gland is equal to 76.2% and the specificity is equal to 85.8%. For diseases of the mammary gland (excluding IDLC) we have discovered that the sensitivity of the method is equal to 94.29% and its specificity equal to 90.91%. In diseases of the mammary gland (including IDLC) we have discovered that the sensitivity of the method is equal to 71.42% and its specificity is equal to 90.91%.
With the help of mathematical methods of pattern recognition the analysis of complex cancer risk factors was conducted aiming at estimation the role of chronic radiation exposure in development of lung and breast cancer in dwellers of an industrial city exposed to irregular radioactive contamination as a result of an accident at PO "Mayak". It was shown, that chronic radiation exposure is an important factor, influenced the development of malignant neoplasms in city population.
BACKGROUND: Patients with type 2 diabetes often suffer from impairments in vision as well as manual dexterity. The purpose of this study was to assess the reliability of dose selection and setting of five insulin devices by patients using auditory and sensory confirmation. METHODS: A total of 48 patients (30 men, 18 women; mean +/- SD age 60.5 +/- 14.0 years; hemoglobin A(1c) 8.7 +/- 1.9%) were randomized to test the following devices: NovoPen 3 (Novo Nordisk A/S, Bagsvaerd, Denmark), HumaPen Ergo (Eli Lilly, Indianapolis, IN), Humalog Pen (Eli Lilly), InnoLet (Novo Nordisk), and FlexPen(Novo Nordisk). RESULTS: Significantly more patients detected an auditory confirmation of dose setting when using the NovoPen 3 compared with the Humalog Pen (P
This paper presents an automated procedure developed to extract quantitative information from video recordings of neonatal seizures in the form of motor activity signals. This procedure relies on optical flow computation to select anatomical sites located on the infants' body parts. Motor activity signals are extracted by tracking selected anatomical sites during the seizure using adaptive block matching. A block of pixels is tracked throughout a sequence of frames by searching for the most similar block of pixels in subsequent frames; this search is facilitated by employing various update strategies to account for the changing appearance of the block. The proposed procedure is used to extract temporal motor activity signals from video recordings of neonatal seizures and other events not associated with seizures.
