Iron stores and coagulation parameters in patients with hypoxemic polycythemia secondary to chronic obstructive pulmonary disease: the effect of phlebotomies.

UNLABELLED This study was designed to determine the effects of phlebotomy on iron body contents and coagulation tests of COPD patients with polycythemia secondary to hypoxemia. Seventeen patients with COPD and hematocrits higher than 54 percent (mean Hct: 57 +/- 0.49 percent), who had not received anti-inflammatory or antiplatelet aggregation agents recently. Their mean forced expiratory volume at 1 second (FEV1) was 0.92 +/- 0.11 L. INTERVENTION Blood work was collected to evaluate the following: serum iron and ferritin levels, total iron binding capacity, transferrin saturation index, fibrinogen plasma levels, activated partial thromboplastin time, platelet count, platelet aggregation measurements, and thromboelastography coagulation parameters. The blood samples were obtained before and about 7 days after the hematocrit correction by 300-400 ml phlebotomies done every other day. The mean number of phlebotomies done for each patient was 4.4. Postphlebotomy iron serum levels decreased from 90.1 +/- 14.8 to 59.7 +/- 9.9 mg/dl and the ferritin serum levels from 133.8 +/- 37.9 to 70.8 +/- 32.7 ng/ml (p < 0.05). Regarding the coagulation studies, there were significant increases in the platelet count, from 227,300 +/- 13,900 to 312,500 +/- 30,200 per mm3, and in the maximum clot amplitude (a) obtained by thromboelastography (from 53.6 +/- 1.4 percent to 60.4 +/- 1.1 percent). The coagulation time (k) of the thromboelastography also decreased significantly, from 7.5 +/- 0.7mm prephlebotomy to 4.5 +/- 0.3mm postphlebotomy. Although the coagulation changes were small amount, the observed significant decrease in iron contents may have clinical implications.
Acute and Chronic Effects of Resistive Exercise on Blood Pressure in Hypertensive Elderly Women

Abstract Mota, MR, de Oliveira, RJ, Dutra, MT, Pardono, E, Terra, DF, Lima, RM, Simões, HG, and da Silva, FM. Acute and chronic effects of resistive exercise on blood pressure in hypertensive elderly women. J Strength Cond Res 27(12): 3475–3480, 2013—The purpose of this study was to investigate postexercise hypotension (PEH) during a 4-month period of resistance training in hypertensive elderly women. Sixty-four women were divided into 2 groups: an experimental group (EG), which performed resistance training, and a control group (CG) that did not practice any exercise. The EG carried out the following steps: (a) 3 weeks of exercise adaptation and 1 repetition maximum (1RM) test (month 1); (b) resistance exercise at 60% 1RM (month 2); (c) resistance exercise at 70% 1RM (month 3); (d) resistance exercise at 80% 1RM (month 4); and (e) PEH analyses at the end of each month. Measurements of systolic (SBP) and diastolic blood pressure (DBP) were calculated each 5 minutes during a 20-minute resting period before the sessions and each 15 minutes during 1 hour of post-session recovery. Analysis of covariance for repeated measures showed a reduction in SBP of about 14 mm Hg (p ⩽ 0.05) and in DBP of 3.6 mm Hg (p ⩽ 0.05) between resting values after the training period. In the EG group, SBP showed acute PEH during months 2 and 3, whereas DBP showed acute PEH during months 2 and 4. The CG did not show acute PEH or variations during the 4-month period. Postexercise hypotension occurrence and chronic reduction of resting blood pressure observed in the EG may have a protective effect on the cardiovascular system of the study participants.
Inactivation and stabilization of stabilisins in neat organic solvents

The stability of the serine proteases from Bacillus amyloliquefaciens (subtillisin BPN') and Bacillus licheniformis (subtilisin Carlsberg) was investigated in various anhydrous solvents at 45°C. The half‐life of subtilisin BPN' in dimethyl‐formamide dramatically depends on the pH of the aqueous solutions from which the enzyme was lyophilized, increasing from 48 min to 20 h when the pH is raised from 6.0 to 7.9. Both subtilisins exhibited substantial inactivation during multihour incubations in tert‐amyl alcohol and acetonitrile when enzymatic activities were also measured in these solvents; however, when the enzymes were assayed in water instead, hardly any loss of activity was detected. This surprising difference appears to stem from the partitioning of the bound water essential for catalytic activity from the enzymes into the solvents. When assayed in organic solvents, this time‐dependent stripping of water results in decay of enzymatic activity; however, when assayed in water, where the dehydrated subtilisins can undergo rehydration thereby recovering catalytic activity, little inactivation is observed. In agreement with this hypothesis, the addition of small quantities of water tert‐amyl alcohol stabilized the subtilisins in it even when enzymatic activity was measured in the nonaqueous solvent. Ester substrates (vinyl butyrate and trichloroethyl butyrate) greatly enhanced the stability of both subtilisins in organic solvents possibly because of the formation of the acyl‐enzymes.
Quantitation of cytomegalovirus (CMV) DNA by real‐time PCR for occurrence of CMV disease in HIV‐infected patients receiving highly active antiretroviral therapy

In HIV‐infected patients treated with highly active antiretroviral therapy (HAART) included in the Predivir cohort, we have evaluated the usefulness of CMV DNA quantitation by a TaqMan® PCR assay from peripheral blood leukocytes (PBLs) to predict CMV disease occurrence. In parallel with the immune restoration after treatment by HAART, the percentage of positive samples decreased progressively from 7.3% at Day 0 to 3.5% at Month 12. Among the CMV markers, the smallest concordance with PBL CMV TaqMan® PCR, as evaluated by kappa, was observed with pp65 antigenemia, whereas concordance with all other CMV markers was high. Among the 16 patients with CMV DNA copies at least once >100/150,000 cells, CMV disease occurred in six during follow‐up, whereas among the 159 patients with CMV DNA copies always <10/150,000 cells, CMV disease occurred in three and among the seven patients with CMV DNA copies >10 and <100 occurred in only one. In univariate Cox models, all the CMV markers including PBL CMV TaqMan® PCR >10/150,000 cells (RR: 27.6, IC95: 7.1–107.2), the CD4 cell count <75 cells/mm3 and the HIV viral load >100,000 copies/ml were predictive for CMV disease. In a stepwise multivariate analysis, which should be interpreted with caution due to the small number of events (n = 10), three covariates were associated independently with CMV disease: pp65 antigenemia >100 nuclei/200,000, PBL CMV TaqMan® PCR >10 copies/150,000 cells and HIV viral load remaining or increasing >100,000 copies/ml.

Determination of the Rate of Transformation from Growth Curves of Transformed Streptococci

A rapid method of determining the rate of transformation of group H streptococci to streptomycin resistance has been developed. The new technique, which involves analysis of the growth response of transformed streptococci in liquid medium containing streptomycin, is independent of chain length fluctuations and is demonstrably more accurate than the standard plating method. The relatively short generation time of streptococci under these conditions permits transformation rates to be estimated in 9 to 14 hr depending on the number of transformants in the inocula as compared to 50 hr by the agar plate procedure.
Fear of childbirth during pregnancy may increase the risk of emergency cesarean section

BACKGROUND The purpose of our study was to elucidate the association between fear of childbirth, general anxiety, and stress coping during the third trimester of pregnancy, and a subsequent delivery by emergency cesarean section. METHODS In a case-control study, 1,981 Swedish-speaking women completed three self-assessment questionnaires at 32 weeks' gestation. Ninety-seven of these women were delivered by emergency cesarean section. Fear of childbirth, general anxiety and the stress coping ability of these 97 cases were compared with the same features in 194 controls, matched for age and parity. RESULTS Women, subsequently delivered by emergency cesarean section, reported a greater anxiety and a poorer stress coping ability, and, most obviously, a greater fear of childbirth at 32 weeks' gestation. After elimination of possible confounders, the odds ratio for emergency cesarean section was examined for women whose scores were above various cut-off points according to the fear of childbirth measuring instrument. For women with a serious fear of childbirth the odds ratio was 3.0 (95% confidence interval 1.4 to 6.6), and the population attributable risk 0.167. CONCLUSION Fear of childbirth during the third trimester of pregnancy may increase the risk of subsequent emergency cesarean section.
Co-creation of Social Innovation: Corporate Universities as Innovative Strategies for Chinese Firms to Engage with Society

Corporate social innovation is a novel, strategic means for enterprise to establish competitive advantage through collaboration with powerful stakeholders, like governments, where firms are simultaneously able to meet social needs and benefit themselves. There is, however limited empirical research investigating how such collaboration enables the co-creation of innovation between firms and society, particularly in emerging markets. In response, this paper takes corporate universities (CUs), a typical manifestation of corporate social innovation, as an example, and explores whether CUs encourage employees to engage in innovation and pro-environmental behaviors, thereby contributing to their firms and local communities in China. Using quantitative methods, we found that employees’ participation in CU training/education courses significantly affects employees’ innovation and environmentally-friendly behaviors in both work and life, and that it enhances their normative commitment (NC) to organizations. Moreover, this commitment mediates employees’ participation in the university program, in terms of both their innovation and pro-environmental behaviors. The main contribution of this paper is to enrich the innovation literature by suggesting a fresh, co-creation mechanism of social innovation between enterprise and government, while offering valuable first-hand evidence in a non-Western context. Our results allow policy makers and stakeholders to gain an in depth understanding of relevant issues.
Printable pneumatic artificial muscles for anatomy-based humanoid robots

We propose a printable, pneumatic artificial muscle with great flexibility in design that is suitable for bio-inspired machines, especially, anatomy-based musculoskeletal robots. This artificial muscle is based on the recently developed thermal fabrication technique of inflatable actuators on sheet materials. In contrast to the cylindrical shape of the McKibben artificial muscle, the proposed actuator has a free two-dimensional shape that is less than 0.1 mm thick. We investigated known morphologies of the muscles in anatomy, such as parallel/pennate muscles, and biceps/triceps muscles. A sample of a 120 mm long and 50 mm wide rectangular muscle with a weight of 1.2 g yielded a maximum output force of up to 35 N at a pressure of 40 kPa. The data showed that the actuator can mimic the properties of the pennate muscle, which has angled muscle fibers. We also implemented muscles with anatomy-based designs on a bionic arm.
The emerging role of microRNA in regulation of endotoxin tolerance

Endotoxin tolerance is a phenomenon where cells show reduced responsiveness toward repeated endotoxin stimulation. Regulation of tolerance occurs at multiple levels of the cell signaling cascade, and many of these levels are potentially regulated by miRNA, which are a class of small RNA that bind to mRNA to down‐regulate gene expression at the post‐transcriptional level. Roles have been identified for miR‐146a, miR‐221, miR‐579, miR‐125b, miR‐155, let‐7e, and miR‐98 in regulating the TLR4 signaling pathway during the development of endotoxin tolerance at receptor, signaling pathway, and gene transcription and translational levels. miRNA represent exciting, new potential targets in attempts to exogenously modulate development of endotoxin tolerance.
Treatment of Community‐Acquired Pneumonia in Adults: Analysis of the National Dispensing Database

Crude national ambulatory antibiotic dispensing data (2007–2011) of adult patients (aged between 20 and below 65 years) with CAP were obtained and expressed as DDD per 1000 inhabitants and per day (DID). European quality indicators of antibiotic prescribing were calculated and adherence rate to the national CAP guideline was assessed. Antibiotic use for CAP in adults ranged between 0.27 and 0.30 DID in various years. The most frequently used antibacterials were levofloxacin, co‐amoxiclav and clarithromycin. Antibiotic use in CAP was compliant with the European recommendations in 6.4% in 2007, which decreased to 4.9% by 2011, in contrast to the optimal compliant range of 80–100%. The consumption of fluoroquinolones mounted up to ~40% in both genders, which exceeded the recommended range (0–5%) substantially. National guideline also favoured the use of macrolides in the empiric therapy of CAP in otherwise healthy adults; hence, guideline‐concordant antibiotic use ranged between 24.0–32.3%. Agents that were contra‐indicated in the empiric therapy of CAP were also used in 6.5–9.0% in various years. These data reflect some worrisome figures and trends in the outpatient antibiotic treatment of adults with CAP. Clarified and updated national guidelines focusing on outpatients and incentives/regulations to increase guideline concordance are warranted.
DIABETES AND PREDIABETES ARE SIGNIFICANTLY HIGHER IN MORBIDLY OBESE CHILDREN COMPARED WITH OBESE CHILDREN.

OBJECTIVE The objective of this study was to examine the prevalence and characteristics of comorbidities in obese and morbidly obese children with a comparison between the 2 sets of children. METHODS This was a retrospective electronic chart review of obese and morbidly obese children and adolescents as defined by body mass index. We evaluated medical history of comorbid conditions, medication use, and cardiovascular risk markers, including blood pressure, lipid profile, and glycosylated hemoglobin. RESULTS There were 1,111 subjects (African American = 635; non-Hispanic white = 364; Hispanic = 36; others = 86), of which 274 were obese and 837 were morbidly obese children with a mean age of 12.7 ± 3.37 years. Morbidly obese children had a higher prevalence of prediabetes (19.5% of obese versus 27.3% of morbidly obese; P<.0001) and type 2 diabetes (39.8% of obese versus 52.4% of morbidly obese; P<.0001). Use of medications for treatment of asthma was significantly higher in the morbidly obese group compared with the obese group (21% versus 14%; P = .01). CONCLUSION Morbidly obese children have a higher prevalence of diabetes, prediabetes, and use of asthma medications compared with obese children.
Fas-Deficient lpr Mice Are More Susceptible to Graft-Versus-Host Disease1

The Fas/Fas ligand (FasL) pathway is involved in a variety of regulatory mechanisms that could be important for the development of graft-vs-host disease (GVHD) after bone marrow transplantation (BMT), such as cytolysis of target cells by cytotoxic T cells, regulation of inflammatory responses, peripheral deletion of autoimmune cells, costimulation of T cells, and activation-induced cell death. To further evaluate the role of Fas/FasL in the complex pathophysiology of GVHD, we used Fas-deficient B6.lpr mice as recipients in a MHC-matched minor histocompatibility Ag-mismatched murine model for GVHD after allogeneic BMT (C3H.SW→B6). We found a significantly higher morbidity and mortality from GVHD compared with control B6 recipients. In contrast, B6.lpr recipients had very little hepatic GVHD, although all other specific GVHD target organs (skin, intestines, and thymus) were more severely affected than in the control B6 recipients. B6.lpr recipients with GVHD demonstrated intact donor lymphoid engraftment and an increase in expansion of donor T cells and monocytes/macrophages compared with control B6 recipients. Serum levels of IFN-γ and TNF-α were higher in B6.lpr recipients than in control B6 recipients, and monocytes/macrophages in B6.lpr recipients appeared more sensitized. B6.lpr recipients had more residual peritoneal macrophages after BMT, and peritoneal macrophages from B6.lpr mice could induce a greater proliferative response from C3H.SW splenocytes. This study demonstrates that the expression of Fas in the recipient is required for GVHD of the liver, but shows unexpected consequences when host tissues lack the expression of Fas for the development of GVHD in other organs and systemic GVHD.
Learning from the mobile payment role model: lessons from Kenya for neighboring Rwanda

ABSTRACT Nationwide adoption of mobile payment (m-payment) has been a key driver for the socio-economic development in emerging markets. The Rwandan m-payment adoption lags behind the one in neighboring Kenya and its own ambition. This explorative study examines the factors that could enhance m-payment adoption in Rwanda. We extend the Technological, Organizational, and Environmental (TOE) framework (Tornatzky, L., & Fleischer, M. (1990). The process of technology innovation. Lexington, MA: Lexington Books) and apply it first to Kenya’s success story of M-Pesa and then to Rwanda’s main m-payment service. Based on our analysis, we determine several anchor points where Rwanda – to improve its economic situation and national welfare – could learn from M-Pesa. Further, we offer country-specific recommendations to enhance Rwanda’s national welfare via m-payment adoption also among the formerly unbanked population.
Factors influencing the implementation of the guideline triage in emergency departments: a qualitative study.

AIMS AND OBJECTIVES The objectives are: (1) to identify factors that influence the implementation of the guideline Triage in emergency departments [2004] in emergency departments in the Netherlands, and (2) to develop tailored implementation strategies for implementation of this guideline. BACKGROUND Guideline dissemination is no guarantee for guideline implementation. In 2004 the guideline Triage in Emergency Departments was disseminated in Dutch hospitals. Guideline revision was scheduled in 2008. Prior to the revision, factors which influenced the implementation of the guideline [2004] were studied to be addressed at the implementation of the revised guideline. METHODS This is an exploratory study using a qualitative design including: a questionnaire sent to all emergency departments in the Netherlands (n = 108): four focus group interviews, including nurses and ward managers and in-depth interviews with ward managers and doctors. Based on the results, tailored implementation strategies and activities were suggested which target the identified influencing factors. RESULTS Various factors at individual, social context and organisational level were identified as influencing the implementation of the 2004 version of the guideline, namely: level of knowledge; insight and skills; work preferences; motivation and/or commitment; support; informed doctors; preliminary work and arrangements for implementation; description of tasks and responsibilities; workload and resources. Ward managers, nurses and doctors mentioned similar as well as different factors. Consequently, tailored implementation strategies and activities related to education, maintenance of change, motivation and consensus-building, information, organisation and facilitation were suggested. CONCLUSION Nurses, ward managers and doctors broadly indicated similar influencing factors, although the importance of these factors differed for the different groups. For nurses, resistance and lack of resources are most important, ward managers mentioned culture and doctors the availability of doctors at the emergency department. RELEVANCE TO CLINICAL PRACTICE Insight into the barriers for implementation and tailoring implementation strategies to these barriers improves the implementation.
Predictors of Blood Pressure Reduction With Nocturnal Continuous Positive Airway Pressure Therapy in Patients With Obstructive Sleep Apnea and Prehypertension

Previous studies showed that treatment of obstructive sleep apnea syndrome (OSAS) with continuous positive airway pressure (CPAP) significantly reduced the blood pressure (BP) in hypertensive patients. We investigated the predictors of BP change in normotensive patients with OSAS who underwent CPAP. A total of 24 patients with OSAS (19 male; age: 48.7 ± 10.4 years) were enrolled. The 24-hour mean BP (24 hMBP), subjective sleepiness, fasting venous blood samples, and anthropometric measurements were assessed at baseline, 6th week and 12th week of CPAP treatment. The 24 hMBP fell at 12 weeks from 89.2 ± 8.4 to 82.9 ± 7.3 mm Hg (P < .0001) irrespective of the severity of disease. Also, both daytime and nighttime BP showed significant reduction after CPAP. Male gender, Epworth sleepiness scale, body mass index, smoking, alcohol use, and baseline 24 hMPB were the independent predictors of a fall in 24 hMBP. The CPAP therapy may provide benefit even in the absence of overt hypertension by reducing both daytime and nighttime BP.
The Influence of Maternal Body Mass Index on Infant Adiposity and Hepatic Lipid Content

Maternal overweight and obesity are associated with adverse offspring outcome in later life. The causal biological effectors are uncertain. Postulating that initiating events may be alterations to infant body composition established in utero, we tested the hypothesis that neonatal adipose tissue (AT) content and distribution and liver lipid are influenced by maternal BMI. We studied 105 healthy mother-neonate pairs. We assessed infant AT compartments by whole body MR imaging and intrahepatocellular lipid content by 1H MR spectroscopy. Maternal BMI ranged from 16.7 to 36.0. With each unit increase in maternal BMI, having adjusted for infant sex and weight, there was an increase in infant total (8 mL; 95% CI, 0.09–14.0; p = 0.03), abdominal (2 mL; 95% CI, 0.7–4.0; p = 0.005), and nonabdominal (5 mL; 95% CI, 0.09–11.0; p = 0.054) AT, and having adjusted for infant sex and postnatal age, an increase of 8.6% (95% CI, 1.1–16.8; p = 0.03) in intrahepatocellular lipid. Infant abdominal AT and liver lipid increase with increasing maternal BMI across the normal range. These effects may be the initiating determinants of a life-long trajectory leading to adverse metabolic health.
Physiotherapy practice in stroke rehabilitation: a survey

Objective : This survey aimed to provide an expert consensus view of the theoretical beliefs underlying physiotherapy practice in stroke rehabilitation the United Kingdom. Method : Questionnaires (with sections related to: therapist background, physiotherapy management, theoretical beliefs and gait re-education strategies used) were posted to all senior level physiotherapists working in stroke care ( n =1022). Results : The majority of respondents had more than 10 years experience overall, and at least 5 years experience in stroke care. The Bobath concept was the preferred approach ( n =67%) followed by an 'eclectic' approach ( n =31%). This survey identified four theoretical themes underlying current practice in neurological physiotherapy: the promotion of normal movement, the control of tone, the promotion of function, and the recovery of movement with optimization of compensation. Conclusions : A consensus was obtained on 16 theoretical beliefs; however the evidence base underlying these beliefs remains sparse. Many of these beliefs require further debate within the physiotherapy profession such as the amount of time spent on preparation for function, the automatic translation of movement into function, carry over outside therapy, and the way in which tasks should be practised.
