Vertebral Strength and Estimated Fracture Risk Across the BMI Spectrum in Women

Somewhat paradoxically, fracture risk, which depends on applied loads and bone strength, is elevated in both anorexia nervosa and obesity at certain skeletal sites. Factor‐of‐risk (Φ), the ratio of applied load to bone strength, is a biomechanically based method to estimate fracture risk; theoretically, higher Φ reflects increased fracture risk. We estimated vertebral strength (linear combination of integral volumetric bone mineral density [Int.vBMD] and cross‐sectional area from quantitative computed tomography [QCT]), vertebral compressive loads, and Φ at L₄ in 176 women (65 anorexia nervosa, 45 lean controls, and 66 obese). Using biomechanical models, applied loads were estimated for: 1) standing; 2) arms flexed 90°, holding 5 kg in each hand (holding); 3) 45° trunk flexion, 5 kg in each hand (lifting); 4) 20° trunk right lateral bend, 10 kg in right hand (bending). We also investigated associations of Int.vBMD and vertebral strength with lean mass (from dual‐energy X‐ray absorptiometry [DXA]) and visceral adipose tissue (VAT, from QCT). Women with anorexia nervosa had lower, whereas obese women had similar, Int.vBMD and estimated vertebral strength compared with controls. Vertebral loads were highest in obesity and lowest in anorexia nervosa for standing, holding, and lifting (p < 0.0001) but were highest in anorexia nervosa for bending (p < 0.02). Obese women had highest Φ for standing and lifting, whereas women with anorexia nervosa had highest Φ for bending (p < 0.0001). Obese and anorexia nervosa subjects had higher Φ for holding than controls (p < 0.03). Int.vBMD and estimated vertebral strength were associated positively with lean mass (R = 0.28 to 0.45, p ≤ 0.0001) in all groups combined and negatively with VAT (R = –[0.36 to 0.38], p < 0.003) within the obese group. Therefore, women with anorexia nervosa had higher estimated vertebral fracture risk (Φ) for holding and bending because of inferior vertebral strength. Despite similar vertebral strength as controls, obese women had higher vertebral fracture risk for standing, holding, and lifting because of higher applied loads from higher body weight. Examining the load‐to‐strength ratio helps explain increased fracture risk in both low‐weight and obese women. © 2015 American Society for Bone and Mineral Research.     

Patient education in Parkinson's disease: Formative evaluation of a standardized programme in seven European countries

OBJECTIVE: To evaluate a newly developed education programme for Parkinson's disease (PD) patients. METHODS: The programme consisted of eight sessions and aimed at improving knowledge and skills related to self-monitoring, health promotion, stress management, depression, anxiety, social competence, and social support, all with special reference to PD. The programme was formatively evaluated in seven European countries (Spain, Finland, Italy, The Netherlands, United Kingdom, Estonia, Germany) with 151 patients diagnosed with idiopathic PD. The evaluation included patients' ratings of the comprehensibility and feasibility of the programme as well as mood ratings before and after each session. Patients also completed questionnaires at the beginning and end of the programme to explore possible changes in disease-related psychosocial problems, quality of life, and depression. RESULTS: The programme was feasible to run, and patients were able to understand its elements. Patients reported mood elevations following individual sessions and reduced disease-related psychosocial problems after completing the programme. There were no substantial differences in results between cultures. CONCLUSION: Patient education appears to have potential as a useful and feasible intervention, complementing medical treatment in PD. PRACTICE IMPLICATIONS: The present programme will soon be available in seven European languages and can be tested in different health care systems.     

Chronic meningitis in systemic lupus erythematosus: An unusual etiology

Chronic aseptic meningitis is a rare manifestation of systemic lupus erythematosus (SLE). Apart from immunological causes and drugs, the aseptic meningitis group can include some unidentified viral infections that cannot be detected by routine microbiological testing. It is imperative to do complete cerebrospinal fluid (CSF) workup before implicating the symptoms to disease activity or drugs, as untreated infections cause significant mortality in SLE. We present a case of young female with SLE who presented with chronic meningitis of an uncommon etiology.     

Leishmanial lipid suppresses tumor necrosis factor alpha, interleukin-1beta, and nitric oxide production by adherent synovial fluid mononuclear cells in rheumatoid arthritis patients and induces apoptosis through the mitochondrial-mediated pathway

OBJECTIVE: Leishmanial lipid is a strong immunosuppressor of host cells. Inhibition of the inflammatory responses of synovial cells through induction of apoptosis is one of the main targets of therapeutic intervention in rheumatoid arthritis (RA). This study was undertaken to examine the antiinflammatory and apoptosis-inducing effects of leishmanial lipid on adherent synovial fluid mononuclear cells (SFMCs) in patients with RA. METHODS: Lipid was extracted from a Leishmania donovani promastigote (MHO/IN/1978/UR6) by the Bligh and Dyer method. Nitric oxide (NO) was measured using the Griess reaction, and enzyme-linked immunosorbent assays for cytokines, NF-kappaB, and cytochrome c were performed. Levels of cytokines, inducible nitric oxide synthase, caspases, Bcl-2, Bax, t-Bid, and cytochrome c in the cell lysate and of NF-kappaB p65 in the nucleus were determined by Western blotting. Microscopic analysis, nuclear staining, DNA fragmentation assay, fluorescence-activated cell sorting, colorimetric assay for caspases, and fluorescent probe for measurement of mitochondrial membrane potential were used to study the leishmanial lipid-induced apoptotic pathway in SFMCs. RESULTS: Leishmanial lipid inhibited the release of tumor necrosis factor alpha, interleukin-1beta, and NO in the culture, decreased their cytosolic protein levels, and decreased NF-kappaB p65 levels in SFMCs, in a dose-dependent manner. It had the reverse effect on interleukin-10 levels. Leishmanial lipid-induced apoptosis involved the activation of caspase 3, caspase 9, and Bax, the release of cytochrome c, the alteration of mitochondrial membrane potential, and the down-regulation of Bcl-2. CONCLUSION: These results suggest that leishmanial lipid has strong antiinflammatory and apoptosis-inducing effects on SFMCs from patients with RA, and that apoptosis occurs via the mitochondrial pathway.

The Utilization of Quality KPIs in the Pharmaceutical Industry

Purpose

The overall aim of this study was to investigate the significance of quality key performance indicators (KPIs) and how comprehensively they are used in the pharmaceutical industry. A specific aim was to find which KPIs were relevant to personnel from the perspective of their own work responsibilities. A further aim was to determine which factors motivate personnel enough to respond to improve KPIs.

Methods

Qualitative theme interviews of ten staff from one case company were conducted to study the impact of KPIs. Interview data were analyzed using qualitative content analysis and reductive analysis.

Results

Personnel considered deviations in manufacturing and packaging to be the most important quality KPI when they considered their own work responsibilities. The quality indicators data were utilized quite efficiently, for example, in complaint and deviation handling processes, and they provided useful information for corrective and preventive actions (CAPA)-reporting. The most important factors that motivated supervisors, managers, and experts regarding KPIs were those that affected interviewees own particular work responsibilities, the cooperation within the operators own departments, and the cooperation between different departments. The interviewees opined that the production bonus was the most important motivational factor for production operators to improve upon quality indicator performance.

Conclusions

Quality indicator feedback data were utilized widely by the case company and were considered to be a useful tool to guide personnel in ensuring or potentially improving the quality of operations.     

Predictors of mortality in children with typhoid ileal perforation in a Nigerian tertiary hospital

Purpose

Childhood typhoid ileal perforation is associated with high morbidity and mortality. Our aim was to ascertain the predictors of survival in children.

Materials and methods

This is a tertiary hospital-based retrospective review of patients aged ≤15 years managed for typhoid ileal perforations between January 2005 and December 2013. The details of their biodata, potential risk factors and outcome were evaluated.

Results

Forty-five children out of a total of 97 with typhoid fever had typhoid ileal perforation. The age range was 2–15 years, mean (±SD) = 9.3 (±3.31) years, median = 10 years. There were more males than females (26:19). Thirty-nine (86.7 %) patients were >5 years old. There were nine deaths (20 % mortality). The mean (±SD) age of survivors was 9.8 (±2.9) years and 7.1 (±4.2) for non-survivors (p = 0.026). The duration of illness at presentation, gender, admission temperature, nutritional status and packed cell volume, perforation-operation interval, number of perforations, surgical procedure, and the duration of surgery did not statistically influence survival (p > 0.05). The age of the patients and burst abdomen attained statistical significance (p < 0.05).

Conclusion

The patients’ age and postoperative burst abdomen were significant determinants of survival in children with typhoid ileal perforation.
