Effects on the maxilla and cranial base caused by cervical headgear : a longitudinal study
2011
Objectives: The aim of this study is to test the possible orthopedic effects of cervical headgear on the cranial base and maxilla. Study design: a sample consisting of 79 subjects with skeletal class II malocclusion was divided into two groups. The experimental group was made up of 41 patients all treated with cervical headgear. The control group included a total of 38 non-treated patients. Each one of these groups was then subdivided according to age into one of three groups: prepubescent, pubescent or post-pubescent. Cephalometric parameters were compared in both groups in order to measure the cranial base angle and the vertical and sagittal position of the maxilla. Additionally, cephalom…
Pet ownership and symptoms of depression: a prospective study of older adults
2020
Abstract Background This paper aims to examine associations between pet ownership and symptoms of depression in a large, population-based sample of older adults. Specifically, we tested whether: (i) people who report more depressive symptoms are more likely to own a pet; (ii) pet ownership protects against an increase in depressive symptoms over time; (iii) associations differ by symptom type. Methods Data were drawn from the English Longitudinal Study of Ageing, a longitudinal panel study of men and women aged 50 and older (n = 7,617, 52.5% female). Pet ownership (dog/cat/other/none) was self-reported in 2010/11. Depressive symptoms were assessed in 2010/11 and 2016/17 using the 8-item cen…
Functional and social discomfort during orthodontic treatment--effects on compliance and prediction of patients' adaptation by personality variables.
2000
During the course of treatment orthodontic patients frequently endure a number of functional complaints and are anxious about their appearance. The aims of this longitudinal study were to follow the progress of patients' adaptation to discomfort, to elucidate the putative relationship between the type of appliance worn and functional and social discomfort experienced, to study potential predictability by their attitude to treatment and to evaluate the effects of discomfort as predictors of patients' compliance. Eighty-four patients undergoing either removable, functional, or fixed appliance treatment monitored their complaints during the first 7 days of treatment and rated them retrospectiv…
Persistent offenders and adolescence-limited offenders: Differences in life-courses.
2020
Background and Aims As our previous study indicated, almost half of juvenile delinquents continued offending in adulthood, while the rest ceased to do so. We compared these groups with each other and with non‐offenders in the life‐course use of alcohol, identity development and life situation. Methods Based on the Jyväskylä Longitudinal Study of Personality and Social Development, four groups were formed at age 42 for men and women: persistent, adolescence‐limited and adult‐onset offenders and non‐offenders. Longitudinal data (N = 369; 53% males) have been collected at ages 8, 14, 20, 27, 36, 42 and 50. Results Persistent offending, but not adolescence‐limited offending, was associated with…
Partners of nulliparous women with severe fear of childbirth: A longitudinal study of psychological well-being.
2018
Background Little is known about the psychological status of partners of women with severe fear of childbirth (FOC). In this longitudinal study from Helsinki University Central Hospital, we investigated FOC, depression, and posttraumatic stress in the partners of women with severe FOC, and possible effects of group psychoeducation and mode of birth.Methods: During pregnancy, 250 partners of nulliparous women with severe FOC participated, 93 in the intervention group and 157 in the control group. At 3 months postpartum, 52 partners in the intervention group and 93 in the control group participated. Both the partners and the childbearing women filled in the Wijma Delivery Expectancy/Experienc…
Friendship Moderates Prospective Associations Between Social Isolation and Adjustment Problems in Young Children
2007
This longitudinal study investigated prospective links between social isolation and adjustment problems among 166 (77 girls, 89 boys) Finnish children ages 7 to 9. Peer nominations for social engagement and self‐reports of internalizing and externalizing problems were collected in the spring of the 1st and 2nd grade. Friendship moderated prospective associations between peer and adjustment variables. Among friended children, there were no prospective associations between social isolation and either internalizing or externalizing problems. Among unfriended children, initial social isolation was positively linked to subsequent increases in internalizing and externalizing problems, and initial…
Long-Term Clinical Outcomes According to Previous Manifestations of Atherosclerotic Disease (from the FAST-MI 2010 Registry)
2017
IF 3.398; International audience; The prognosis of patients with acute myocardial infarction (AMI) has notably improved in the past 20 years. Using the French Registry of ST-Elevation and Non-ST-elevation Myocardial Infarction (FAST-MI) 2010 registry, we investigated whether previous manifestations of atherosclerotic disease (i.e., previous MI, or a history of any form of atherosclerotic disease) are at truly increased risk compared with those in whom AMI is the first manifestation of the disease. FAST-MI 2010 is a nationwide French registry including 3,079 patients with AMI, among whom 1,062 patients had a history of cardiovascular atherosclerotic disease and 498 patients had a history of …
The Healthy Nordic Diet and Mediterranean Diet and Incidence of Disability 10 Years Later in Home-Dwelling Old Adults.
2019
Background/Objective: Diet has a major impact on a person's health. However, limited information exists on the long-term role of the whole diet on disability. We investigated the association of the healthy Nordic diet and the Mediterranean diet with incident disability 10 years later. Design: Longitudinal, with a follow-up of 10 years. Settings/Participants: A total of 962 home-dwelling men and women from the Helsinki Birth Cohort Study, mean age 61.6 years, who were free of disability at baseline. Measurements: At baseline, 2001-2004, the Nordic diet score (NDS) and modified Mediterranean diet score (mMDS) were calculated using a validated 128-item food-frequency questionnaire. Higher scor…
Management of elderly patients suffering from cancer: Assessment of perceived burden and of quality of life of primary caregivers
2017
International audience; Objective: To evaluate the perceived burden and the quality of life (QoL) at 3 and 6 months of the primary caregiver (PC) of patients aged 70 and over suffering from cancer and the predictors of QoL in this population.Methods: In this prospective observational study, 98 patients aged 70 and older with cancer and 96 PCs were included between 01/06/2014 and 18/03/2015. The Medical Outcomes Study 12-item Short Form Health Survey (SF-12) was used to assess the QoL of PCs and the Zarit Burden Interview (ZBI) was used to measure the perceived burden at 3 and 6 months. The major determinants of QoL were identified using mixed linear models for the dimensions of the SF-12 th…
Widespread pain among 11-year-old Finnish twin pairs
2001
Objective To examine the prevalence of widespread musculoskeletal pain (WSP) symptoms in 11-year-old Finnish twins and to determine the relative role of genetic and environmental factors in the etiology of WSP. Methods Data on current pain items were collected from 1995 to 1998 from a national sample of Finnish families with 11-year-old twins born between 1984 and 1987. The presence of WSP was determined using a validated questionnaire method. Pairwise similarity was computed for 583 monozygotic (MZ) pairs, 588 same-sex dizygotic (DZ) pairs, and 618 opposite-sex DZ twin pairs. Variance components for genetic and environmental factors were estimated using biometric structural equation modeli…
