Longitudinal Development of Mother–Infant Interaction During the First Year of Life Among Mothers with Substance Abuse and Psychiatric Problems and Their Infants

The quality of mother–infant interaction during the first year may be hampered by maternal substance abuse and co-existing non-optimal factors such as psychiatric problems and difficult relational experiences. In the present study three groups of women were recruited during pregnancy: One group with substance abuse problems from residential treatment centers (n = 28), a second group from psychiatric outpatient treatment centers (n = 22), and a third group from well-baby clinics (n = 30). Four maternal optimality indexes were assessed (substance abuse, psychiatric problems, relational experiences and SES). Mother–infant interaction was observed at 3 and 12 months. The substance abuse group showed the most disturbed mother–infant interaction at 12 months. Low maternal optimality as well as impairments in maternal affective involvement at 3 months influenced negatively both on infant and dyadic affective behavior in interaction at 12 months. Long-term interventions are needed to promote affective reciprocity among mother–baby pairs with low optimality.     

Hematological features in adolescents with periodontitis

The aim of this study was to assess whether adolescent cases of periodontitis present with different hemogram findings than control subjects. This case-control study comprised 87 adolescent cases presenting with clinical attachment loss ≥3 mm in at least two teeth and 73 control subjects. Blood samples were obtained by venipuncture and analyzed in an Abbott Cell-Dyn 3,500 hematology analyzer for values of white blood cells and red blood cells, hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, red-cell distribution width, platelets, and mean platelet volume. Hematocrit values were obtained using volume fractions read from capillary tubes. The associations between log-transformed hemogram variables with each of the three exposure variables "case status" (yes/no), a "high percent sites with PD ≥4 mm" (yes/no), and a "high percent sites with BOP" (yes/no) were investigated using multivariate linear regression analyses. Periodontitis cases presented with 5% higher values for the mean platelet volume than did controls. Subjects with a high percent sites with probing depth ≥4 mm had eosinophil counts that were on average 27% lower than among subjects with fewer deepened pockets. They also had 7% higher values for the mean platelet volume than did persons with less pocketing. Eosinophil counts and mean platelet volumes may be associated with the parameters of periodontitis in adolescents. While standard hematological testing did not show abnormalities in adolescents with periodontitis compared to healthy controls, eosinophil counts and mean platelet volumes may reflect periodontal inflammation.     

A 24-month evaluation of amalgam and resin-based composite restorations: Findings from The National Dental Practice-Based Research Network

BackgroundKnowing which factors influence restoration longevity can help clinicians make sound treatment decisions. The authors analyzed data from The National Dental Practice-Based Research Network to identify predictors of early failures of amalgam and resin-based composite (RBC) restorations.MethodsIn this prospective cohort study, the authors gathered information from clinicians and offices participating in the network. Clinicians completed a baseline data collection form at the time of restoration placement and annually thereafter. Data collected included patient factors, practice factors and dentist factors, and the authors analyzed them by using mixed-model logistic regression.ResultsA total of 226 practitioners followed up 6,218 direct restorations in 3,855 patients; 386 restorations failed (6.2 percent) during the mean (standard deviation) follow-up of 23.7 (8.8) months. The number of tooth surfaces restored at baseline helped predict subsequent restoration failure; restorations with four or more restored surfaces were more than four times more likely to fail. Restorative material was not associated significantly with longevity; neither was tooth type. Older patient age was associated highly with failure (P N/A .001). The failure rate for children was 4 percent, compared with 10 percent for people 65 years or older. Dentist’s sex and practice workload were associated significantly with restoration longevity.ConclusionsIn this prospective cohort study, these factors were significantly predictive of failure for amalgam and RBC restorations: patient’s age, a higher number of surfaces restored at baseline, the dentist’s sex and the practice workload. Material choice was not significantly predictive in these early results.Practical ImplicationsIf clinicians can recognize and identify the risk factors associated with early restoration failure, more effective treatment plans may be offered to the patient.     

Improvements in health-related quality of life after treatment with tocilizumab in patients with rheumatoid arthritis refractory to tumour necrosis factor inhibitors: results from the 24-week randomized controlled RADIATE study

Objective. To investigate the effect of tocilizumab on patient-reported outcomes (PROs) in RA patients with inadequate responses to TNF inhibitors (TNFis). Methods. In a Phase III randomized controlled trial, 489 patients received 4 or 8 mg/kg tocilizumab or placebo every 4 weeks plus MTX for 24 weeks. Mean changes from baseline over time and proportions of patients reporting improvements greater than or equal to minimum clinically important differences (MCIDs) in PROs were analyzed. Results. At week 24, 8?mg/kg resulted in significantly greater improvements vs placebo in pain, global assessment of disease activity (P?=?0.001), Health Assessment Questionnaire-Disability Index (HAQ-DI; P?相似文献   

The effect of a pre- and post-operative orthogeriatric service on cognitive function in patients with hip fracture. The protocol of the Oslo Orthogeriatrics Trial

ABSTRACT: BACKGROUND: Hip fracture mainly affect older people. It is associated with high morbidity and mortality, and in particular a high frequency of delirium. Incident delirium following hip fracture is associated with an increased risk of dementia in the following months, but it is still not firmly established whether this is an association or a causal relationship. Orthogeriatric units vary with respect to content and timing of the intervention. One main effect of orthogeriatric care may be the prevention of delirium, especially if preoperative and postoperative care are provided. Thus, the aim of Oslo Orthogeriatric Trial, is to assess whether combined preoperative and postoperative orthogeriatric care can reduce the incidence of delirium and improve cognition following hip fracture. Methods/design: Inclusion and randomisation will take place in the Emergency Department, as soon as possible after admission. All patients with proximal femur fractures are eligible, irrespective of age, pre-fracture function and accommodation, except if the fracture is caused by a high energy trauma or the patient is terminally ill. The intervention is pre-and post-operative orthogeriatric care delivered on a dedicated acute geriatric ward. The primary outcome measure is a composite endpoint combining the Clinical Dementia Rating Scale (CDR) and the 10 word memory task at four months after surgery. Secondary outcomes comprise incident delirium, length of stay, cognition, mobility, place of residence, activities of daily living and mortality, measured at 4 and 12 months after surgery. We have included 332 patients in the period 17th September 2009 to 5th January 2012. DISCUSSION: Our choice of outcome measures and our emphasis of orthogeriatric care in the preoperative as well as the postoperative phase will enable us to provide new knowledge on the impact of orthogeriatric care on cognition.
