Morale in the oldest old: the Umeå 85+ study

OBJECTIVE: to describe morale among the oldest old, and to investigate which social, functional and medical factors are associated with morale in this population. DESIGN: a cross-sectional study. SETTING: a population-based study in the municipality of Ume?, a city in Northern Sweden. SUBJECTS: half of the 85-year-old population, and the total population of 90-year-olds and > or = 95-year-olds (95-103) were asked to participate (n = 319) and 238 were interviewed. METHODS: structured interviews and assessments during home visits, interviews with relatives and caregivers and review of medical charts. The 17-item Philadelphia Geriatric Center Morale Scale (PGCMS) was used to measure morale. Participants were assessed with the Barthel Activities of Daily Living (ADL) Index, Geriatric Depression Scale (GDS-15), Mini-Mental State Examination (MMSE), Mini Nutritional Assessment (MNA), and a symptom questionnaire. Multiple regression analyses were conducted to find independent factors to explain the variation in the PGCMS score. RESULTS: eighty-four per cent (n = 199) of those interviewed answered the PGCMS. Three-quarters had middle range or high morale. GDS score, type of housing, previous stroke, loneliness and number of symptoms, adjusted for age group and sex, explained 49.3% of the variance of total PGCMS score. CONCLUSIONS: a large proportion of the oldest old had high morale. The most important factors for high morale were the absence of depressive symptoms, living in ordinary housing, having previously had a stroke and yet still living in ordinary housing, not feeling lonely and low number of symptoms. The PGCMS seems applicable in the evaluation of morale among the oldest old.     

In situ fixation of slipped capital femoral epiphysis with Steinmann pins

Background and purpose

Slipped capital femoral epiphysis (SCFE) is often treated by surgical fixation; however, no agreement exists regarding technique. We analyzed the outcome of in situ fixation with Steinmann pins.

Patients and methods

All 67 subjects operated for slipped capital femoral epiphysis at Haukeland University Hospital during the period 1990–2007 were included. All were treated by in situ fixation with 2 or 3 parallel Steinmann pins (8 mm threads at the medial end). The follow-up evaluation consisted of clinical examination and hip radiographs. Radiographic outcome was based on measurements of slip progression, growth of the femoral neck, leg length discrepancy, and signs of avascular necrosis and chondrolysis.

Results

67 subjects (41 males) were operated due to unilateral slips (n = 47) or bilateral slips (n = 20). Mean age at time of diagnosis was 13 (7.2–16) years. Mean age at follow-up was 19 (14–30) years, with a mean postoperative interval of 6.0 (2–16) years. The operated femoral neck was 9% longer at skeletal maturity than at surgery, indicating continued growth of the femoral neck. At skeletal maturity, 12 subjects had radiographic features suggestive of a previous asymptomatic slip of the contralateral hip. The total number of bilateral cases of SCFE was 32, i.e half of the children had bilateral SCFE. 3 subjects required additional surgery and mild avascular necrosis of the femoral head was seen in 1 patient. None had slip progression or chondrolysis.

Interpretation

In situ pinning of SCFE with partly threaded Steinmann pins appears to be a feasible and safe method, with few complications. The technique allows further growth of the femoral neck.Slipped capital femoral epiphysis (SCFE) is a disease of unknown etiology, but mechanical, biological and hereditary factors are likely to play a role (Barrios et al. 2005, Murray and Wilson 2008). The rationale for treatment of SCFE is to restore hip function, prevent further slip, and to reduce the risk of subsequent degenerative changes. Several surgical techniques have been recommended such as cannulated screws (Chen et al. 2009), hook-pins (Hansson 1982), specially constructed screws (Wensaas and Svenningsen 2005), and most recently surgical hip dislocation with subcapital correction osteotomy (Leunig et al. 2007). However, currently there is no evidence to support the superiority of one particular technique over another.In situ fixation is advocated by most authors (Boyer et al. 1981, Carey et al. 1987, Givon and Bowen 1999) since peroperative reduction may increase the risk of avascular necrosis (Ordeberg et al. 1983, Carney et al. 1991, Lim et al. 2007). Physiodesis to prevent further growth—thus stabilizing the physis—is recommended by some authors (Carey et al. 1987, Aronsson and Karol 1996). Slip of the contralateral hip is reported in more than half of the cases (Hägglund et al. 1988, Castro et al. 2000) and controversies exist regarding prophylactic fixation of the contralateral hip. According to Jerre et al. (1994), more than two-thirds of the contralateral slips are asymptomatic and are therefore only detected at close follow-ups including hip radiographs at short intervals. Immediate prophylactic fixation of the contralateral hip has been advocated by several authors (Hägglund et al. 1988, Schultz et al. 2002, Krauspe et al. 2004).In this paper, we present clinical and radiographic results of a novel, simple technique for in situ fixation of the femoral head with partially threaded Steinmann pins to enable further growth of the femoral neck.     

Effect of a high-intensity functional exercise program on functional balance: preplanned subgroup analyses of a randomized controlled trial in residential care facilities

OBJECTIVES: To evaluate whether age, sex, depression, dementia disorder, nutritional status, or level of functional balance capacity influences the effect of a high‐intensity functional weight‐bearing exercise program on functional balance. DESIGN: Preplanned subgroup analyses of a randomized controlled trial. SETTING: Nine residential care facilities. PARTICIPANTS: One hundred ninety‐one people aged 65 to 100 dependent in activities of daily living and with Mini‐Mental State Examination scores of 10 or greater. INTERVENTION: A high‐intensity functional weight‐bearing exercise program or a control activity, each comprising 29 sessions over 3 months. MEASUREMENTS: Functional balance capacity was assessed blindly using the Berg Balance Scale (BBS) at baseline, 3 months, and 6 months. The BBS consists of 14 tasks, common in everyday life, such as standing up from sitting and, while standing, reaching forward or turning 360°. Interactions between allocation to activity group and each subgroup were evaluated according to the intention‐to‐treat principle. RESULTS: The subgroup analyses revealed no statistically significant interaction for age, sex, depression, dementia disorder, nutritional status, or level of functional balance capacity at 3 (P=.65, .65, .51, .78, .09, .67, respectively) or 6 (P=.69, .62, .20, .94, .48, .85, respectively) months. In addition, at 3 and 6 months there was no significant interaction for cognitive level (P=.28, .47, respectively) or number of depressive symptoms (P=.85, .49, respectively). CONCLUSION: Older age, female sex, depression, mild to moderate dementia syndrome, malnutrition, and severe physical impairment do not seem to have a negative effect on functional balance from a high‐intensity functional weight‐bearing exercise program. Consequently, people with these characteristics in residential care facilities should not be excluded from offers of rehabilitation including high‐intensity exercises.     

Design of homogeneous, monopegylated erythropoietin analogs with preserved in vitro bioactivity

OBJECTIVE: Erythropoietin (Epo) bioactivity is significantly reduced by modification of lysine residues with amine-reactive reagents, which are the most commonly used reagents for attaching polyethylene glycols (PEGs) to proteins to improve protein half-life in vivo. The aims of this study were to determine whether Epo bioactivity can be preserved by targeting attachment of maleimide-PEGs to engineered cysteine analogs of Epo, and to determine whether the pegylated Epo cysteine analogs have improved pharmacokinetic properties in vivo. MATERIALS AND METHODS: Thirty-four Epo cysteine analogs were constructed by site-directed mutagenesis and expressed as secreted proteins in baculovirus-infected insect cells. Following purification, monopegylated derivatives of 12 cysteine analogs were prepared using 20-kDa maleimide-PEGs. In vitro biological activities of the proteins were measured in an Epo-dependent cell proliferation assay. Plasma levels of insect cell-expressed wild-type Epo (BV Epo) and a pegylated Epo cysteine analog were quantitated by ELISA following intravenous administration to rats. RESULTS: Biological activities of 17 purified Epo cysteine analogs and 10 purified pegylated Epo cysteine analogs were comparable to that of BV Epo in the in vitro bioassay. The only pegylated cysteine analogs that displayed consistently reduced in vitro bioactivities were substitutions for lysine residues, PEG-K45C and PEG-K154C. The pegylated Epo cysteine analog had a slower initial distribution phase and a longer terminal half-life than BV Epo in rats, but the majority of both proteins were cleared rapidly from the circulation. CONCLUSIONS: Targeted attachment of maleimide-PEGs to engineered Epo cysteine analogs permits rational design of monopegylated Epo analogs with minimal loss of in vitro biological activity. Insect cell-expressed Epo proteins are cleared rapidly from the circulation in rats, possibly due to improper glycosylation. Site-specific pegylation appears to improve the pharmacokinetic properties of Epo.

Fracture of Colvin-Galloway-Future band in a patient with mitral valve annuloplasty

Annuloplasty with various annuloplasty ring systems is a fundamental part of mitral valve repair and has been frequently performed since its introduction by Carpentier in 1969. Due to the different advantages or disadvantages of each system, some controversies exist regarding the best type of ring annuloplasty support. Here we describe, for the first time, the case of a female patient in which a fracture of a semi-rigid open annuloplasty ring occurred, leading to annular deformation and mitral regurgitation.     

Low Physical Activity Is a Predictor of Thinness and Low Self-rated Health: Gender Differences in a Swedish Cohort

PurposeTo examine the relationship between leisure time physical activity in 15-year-old students, and weight status and self-rated health 3 years later.MethodsData were used from two follow-up waves, one in 2002 (grade 9, age 15 years) and one in 2005 (grade 12, age 18 years) of a cohort of approximately 2,500 adolescents. Adolescents reported height and weight, health behaviors, and self-rated health by a questionnaire at both occasions. Age and gender-specific body mass index cut-off points for thinness, overweight, and obesity were used to assess weight status. Logistic regression analyses were performed with weight status and self-rated health as the outcomes and level of leisure time physical activity as the independent variable. Adjustments were made for parental years of education, student's current smoking habits, and baseline body mass index.ResultsAs compared with students who were active for more than 4 hours per week during leisure time, being active 2–4 hours (odds ratio [OR]: 4.15, confidence interval [CI]: 1.62–10.60) and <2 hours (OR: 3.92, CI: 1.30–11.78) predicted thinness in boys. In girls, the risk was smaller and became significant at <2 hours per week (OR: 2.57, CI: 1.38–4.77). Overweight or obesity was not significantly predicted by physical activity. A significant risk of low self-rated health was found at follow-up in boys active for <4 hours per week compared with those active for >4 hours per week.ConclusionPhysical activity is important to maintain a healthy body weight and for future self-rated health in boys.
