Completeness and timeliness of diphtheria-tetanus-pertussis,measles-mumps-rubella,and polio vaccines in young children with chronic health conditions: A systematic review

Objective

To systematically review literature on uptake and timeliness of diphtheria-tetanus-pertussis, measles-mumps-rubella, and/or polio-containing vaccines in infants who were born preterm, with a low birth weight, and/or with chronic health conditions that were diagnosed within the first 6?months of life.

Promoting autonomy and independence for older people within nursing practice: a literature review

The principles of promoting autonomy and independence underpin many approaches to improving the quality of nursing care for older people in whatever setting, and are in line with wider developments in health care such as the Patient's Charter. However, these concepts require careful definition if nursing practices which might promote autonomy and independence are to be identified. Although the generalizability of the research-based literature in this field is limited by a focus upon older people in continuing-care settings, a review of the literature found a number of indicators associated with attempts to promote patient autonomy and independence. These were grouped into the following categories: systems of care delivery which promote comprehensive individualized assessment and multidisciplinary care planning; attempts to encourage patients/clients to participate in decisions about their care; patterns of communication which avoid exerting power and control over patients/clients and attempts to modify the environment to promote independence and minimize risk. It is suggested that the review identifies a number of principles for nursing practice which can be applied in a range of care settings in order to promote the autonomy and independence of older people.

Dentoskeletal treatment changes in Class II subdivision malocclusions in submentovertex and posteroanterior radiographs.

The objective of this study was to evaluate the dentoskeletal changes consequent to orthodontic treatment in subjects with Class II subdivision malocclusions, treated with asymmetric extractions, compared with a normal-occlusion control group. The sample consisted of 3 groups, with 30 subjects in each: normal-occlusion subjects (group 1), untreated Class II subdivision subjects (group 2), and Class II subdivision patients treated with asymmetric extractions (group 3). All subjects had a full complement of permanent teeth at the beginning of treatment. The average ages of the subjects were 22.42, 15.76, and 18.57 years, respectively, in groups 1, 2, and 3. Measurements of relative differences in the spatial position of dental and skeletal bilateral landmarks were obtained from the submentovertex and posteroanterior cephalometric (PA) radiographs. The t test for independent samples was used to compare group 1 with groups 2 and 3 at different times. Results from the submentovertex radiograph showed that asymmetric extractions in Class II subdivision malocclusions will maintain the differences in the anteroposterior positions of right and left, maxillary and mandibular first molars, as would be expected with the treatment protocols used. There were no significant skeletal changes that could be attributed to the treatment approaches investigated or transverse collateral effects with the asymmetric mechanics used. It was also demonstrated that treatment of Class II subdivision malocclusions with asymmetric extractions produced corrections of maxillary and mandibular dental midline deviations with the midsagittal plane, without canting the occlusal plane or any other investigated horizontal plane, as seen in the PA radiograph. Treatment of Class II subdivision malocclusions with asymmetric extractions constitutes a beneficial approach to this problem.     

Postretention relapse of mandibular anterior crowding in patients treated without mandibular premolar extraction.

Treatment stability is one of the most important objectives in orthodontics, but, despite decades of research, it is still agreed that the stability of aligned teeth is variable and largely unpredictable. This study aimed to evaluate the relapse of mandibular anterior crowding in patients treated without mandibular premolar extraction. The sample comprised 40 patients of both sexes with Class I or II malocclusions who received nonextraction treatment in the mandibular arch with edgewise mechanics. Lateral cephalograms and dental casts of each patient were obtained at pretreament, posttreatment, and 5 years postretention. Relapse of mandibular anterior crowding was assessed, and associations between this relapse and other clinical factors were also investigated. Mandibular anterior crowding was measured by the Little irregularity index, and the data were evaluated by the Mann-Whitney test. The mean relapse of mandibular anterior crowding was 1.95 mm (26.54%) over the long term. No clinical factor studied was predictive of crowding relapse in the long term.     

Why do some overweight children experience psychological problems? The role of weight and shape concern.

OBJECTIVE: To examine the associations between weight status, weight and shape concern, self-esteem, body dissatisfaction and depression in children. METHODS: Interviews were conducted with 7- to 13-year-old overweight (n = 89) and healthy weight (n = 118) children, using the Child Eating Disorder Examination, Self-Perception Profile for Children, Children's Body Image Scale and Child Depression Inventory. RESULTS: Overweight children were more concerned about weight and shape than healthy weight children. After controlling for BMI z-score, children with high weight and shape concern reported lower self-esteem, higher body dissatisfaction and higher depression than children with low weight and shape concern. Concern about weight and shape mediated the relationships between BMI z-score and low self-esteem, body dissatisfaction and depression. CONCLUSIONS: Results support the hypothesis that differences in weight and shape concern, within samples of overweight and healthy weight children, can account for differences in degree of psychological distress. Findings have implications for the prevention and treatment of psychological problems in overweight children.     

Development of a flow cytometry based method for rapid and sensitive detection of a novel marine fish iridovirus in cell culture

A sensitive and accurate flow cytometry (FCM) based method has been developed to detect and quantitate a novel marine fish iridovirus (Singapore grouper iridovirus, SGIV) after amplification in cell cultures. Confluent grouper cell (GP) monolayers were infected with SGIV. When advanced cytopathic effect (CPE) appeared, the cell cultures were fixed and permeabilized, and then reacted with monoclonal antibodies specific against SGIV, followed by a second antibody conjugated with FITC (anti-mouse IgG-FITC). A Coulter EPICS Elite ESP flow cytometer was used to directly detect and analyze the percentage of virus-infected cells. Three fixation and permeabilization methods were evaluated. The kinetics of the virus infection process was determined. The FCM procedure enables large amounts of cells to be screened rapidly for infectivity, and it can also detect low levels of virus infection. As early as 8 h after inoculation with the virus, 0.34% of infected cells were detected in cell culture. The maximum level of infection was obtained at 72 h. The efficiency and reliability of the FCM procedure were compared with those of the standard methods of immunofluorescence microscopy and PCR.
