    Bone resorption associated with local trauma occurring during insertion of joint prostheses is recognized as an early event. Being an osteoclastic inhibitor, alendronate is a potential candidate means to decrease early periprosthetic bone resorption and thereby improve implant fixation. We...... investigated the influence of oral alendronate treatment on early implant fixation in two implant interface settings representing sites of an implant that are in contact with surrounding bone, and other sites without intimate bone contact. One plasma-sprayed cylindrical titanium implant (6 mm diameter) was...... inserted into each proximal tibia of 16 dogs. On one side the implant was inserted press-fit whereas on the contralateral side, the implants were surrounded by a 2 mm concentric gap. Oral alendronate (0.5 mg/kg/day) was given 2 weeks following surgery to eight dogs. The dogs were euthanized after 10 weeks...

    Full Text Available Background: Morinda citrifolia Linn (noni, as a “pain killer”, has been used as a traditional medicine by Polynesians for over 2000 years. It was reported to have a broad range of therapeutic effects including analgesic and anti-inflammation. The in-vitro and in vivo antiinflammatory and analgesic properties of noni juice (NJ suggest that NJ may be a useful adjunctive treatment for osteoarthritis (OA. In this pilot study we explored whether NJimproves the symptoms and Quality of Life (QoL for adults with OA. We also sought toevaluate the tolerability and safety of NJ for patients with OA in a primary care setting. Methods: This was an open label three-month intervention pilot study. Data were collected by pre/post intervention survey and laboratory testing. Inclusion criteria were: adults of both sexes aged 40 to 75, with a diagnosis of OA on the hip or knee by x-ray examination provided by theirprimary care physician, not on prescription medicine for OA, and who were willing to drink 3 oz of NJ a day for 90 days. Results: Of the 64 questions measuring different aspects of QoL asked on the pre/post survey, 49 (77% had significant pre/post mean scale differences as measured by independent t-test. The OA patients reported being significantly more satisfied with their current health conditions including mobility, walking and bending, hand, finger, and arm functions, household tasks, social activity, arthritis pain, work ability, level of tension, and mood. The study participantswere also more positive about their future health and reported taking less over-the-counter (OTC pain relievers. Pre/post laboratory testing including: lipid panel, liver and kidney functions were in the normal ranges. High Sensitive C Reactive Protein (hsCRP, an inflammatory biomarker, was reduced by 10% after the intervention. Conclusion: As a nutritional supplement, NJ demonstrated a potential therapeutic effect and improved the symptoms and the QoL for adults with OA

    An increase in procollagen type I amino-terminal propeptide (PINP) early after teriparatide initiation was shown to correlate with increased lumbar spine areal BMD and is a good predictor of the anabolic response to teriparatide. Few data exist correlating PINP and bone microstructure, and no data exist in patients on teriparatide following prior potent antiresorptive treatment. This exploratory analysis aimed to investigate the effects of teriparatide on cancellous bone microstructure and correlations of bone markers with microstructure in alendronate-pretreated patients. This was a post hoc analysis of changes in bone markers and three-dimensional indices of bone microstructure in paired iliac crest biopsies from a prospective teriparatide treatment study in postmenopausal women with osteoporosis who were either treatment-naïve (TN, n=16) or alendronate-pretreated (ALN, n=29) at teriparatide initiation. Teriparatide (20μg/day) was given for 24months; biopsies were taken at baseline and endpoint, and serum concentrations of PINP and type 1 collagen cross-linked C-telopeptide (βCTX) were measured at intervals up to 24months. In the TN and ALN groups, respectively, mean (SD) increases in three-dimensional bone volume/tissue volume were 105 (356)% (P=0.039) and 55 (139)% (P<0.005) and trabecular thickness 30.4 (30)% (P<0.001) and 30.8 (53)% (P<0.001). No significant changes were observed in trabecular number or separation. In the ALN patients, 3-month change of neither PINP nor βCTX correlated with indices of cancellous bone microstructure. However, 12-month changes in biochemical bone markers correlated significantly with improvements in bone volume/tissue volume, r=0.502 (P<0.01) and r=0.378 (P<0.05), trabecular number, r=0.559 (P<0.01) and r=0.515 (P<0.01), and reduction of trabecular separation, r=-0.432 (P<0.05) and r=-0.530 (P<0.01), for PINP and βCTX, respectively. We conclude that cancellous bone microstructure improved with teriparatide therapy

    Alendronate is an antiosteolytic agent under investigation for the treatment of a number of bone disorders. Since the compound is a zwitterion with five pKa values and is completely ionized in the intestine at the physiological pH, absorption is poor; less than 1% of an oral dose is available systemically in rats. In the present studies, absorption was found to be predominantly in the upper part of the small intestine. Administration of buffered solutions of alendronate (pH 2-11) did not improve absorption. Whereas food markedly impaired the absorption of alendronate, EDTA enhanced absorption in a dose-dependent manner. Pretreatment of rats with ulcerogenic agents, mepirizole, acetylsalicylic acid, or indomethacin, resulted in a 3-7-fold increase in the oral absorption of alendronate. The absorption of phenol red, added as an indicator of intestinal tissue damage, was also increased in rats with experimental peptic ulcers. The enhanced absorption of alendronate observed in rats with experimental peptic ulcers was attributed to the alteration of the integrity of the intestinal membrane. PMID:7891304

  8. Evaluation of QOL in cancer patients treated with radiation therapy

    International Nuclear Information System (INIS)

    Evaluation of quality of life (QOL) in cancer patients is an important theme. However, we do not have an established method to assess QOL in cancer patients during radiotherapy in Japan. We evaluated both the changes of QOL and the factors affecting QOL in radiotherapy patients. Three hundred fifty-five cancer patients, who filled in a questionnaire at the beginning, middle, and end of radiotherapy between 1998 and 2001, were studied. We used The QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs (QOL-ACD)'' devised by Kurihara et al, the Ministry of Health and Welfare. The QOL Questionnaire had five categories: physical activity, physical condition, mental state, social interaction, and face scale. The total score, sum of the score of five categories, were established synthetically (maximum score is 110). The mean of total QOL scores were 75.8, 77.6, and 78.2 at the beginning, middle, and end of radiotherapy respectively. Patients with symptoms related to cancer had apparent improvement of QOL score. Patients receiving chemotherapy had a decreased QOL score at the end of radiotherapy. The score of physical condition was reduced improvement. It was suggested that radiotherapy could be performed without losing QOL of cancer patients, including older patients. However, patients receiving chemotherapy and those with head and neck cancer may lose their QOL, therefore, we should treat such patients carefully. (author)

Titanium (Ti) is used in the field of orthopedic and dental implants because of its excellent biocompatibility and outstanding mechanical properties. Therefore, in the field of materials science and tissue engineering, there has been extensive research to immobilize bioactive molecules on the surface of implant materials in order to provide the implants with improved adhesion to the host bone tissue. In this study, chemically active functional groups were introduced on the surface of Ti by a grafting reaction with heparin and then the Ti was functionalized by immobilizing alendronate onto the heparin-grafted surface. In the MC3T3-E1 cell osteogenic differentiation study, the alendronate-immobilized Ti substrates significantly enhanced alkaline phosphatase activity (ALP) and calcium content. Additionally, nuclear factor kappa B ligand (RANKL)-induced osteoclast differentiation of RAW264.7 cells was inhibited with the alendronate-immobilized Ti as confirmed by TRAP analysis. Real time PCR analysis showed that mRNA expressions of osteocalcin and osteopontin, which are markers for osteogenesis, were upregulated in MC3T3-E1 cells cultured on alendronate-immobilized Ti. The mRNA expressions of TRAP and Cathepsin K, markers for osteoclastogenesis, in RAW264.7 cells cultured on alendronate-immobilized Ti were down-regulated.

    The evaluation of QOL (Quality of Life) in the medical field has revolved around the development of self-measurement scales comprising two or more questions based on psychometric theory. QOL research in the field of child health progressed in the latter half of the 80s in the United States, and aspects of ambiguity and adaptation to the environment of children were recognized. Objective health and subjective health differ significantly among children and are strongly influenced by environmental factors. In addition, QOL in early life anticipates the later health status in adolescence and youth. For these reasons, QOL research in the field of child health is very important. More than 20 scales, exemplified by CHQ, PedsQL, TACQOL/TAPQOL, and COOP charts, exist as standard generic QOL indices for children. Disease-specific scales cover epilepsy, asthma, and allergic disease, as discussed in a number of early studies. Diabetes, skin disease, and cancer are also major research subjects. Self-evaluation is one of the principles of QOL research; it is stated that children in the age group of 5-6 years are already capable of expressing pain and their physical condition and that the competency to describe abstract concepts such as pride and happiness matures around the age of 9-10 years. Sources of information such as the computer have developed and spread remarkably in recent years. The use of such technology facilitates the evaluation of young children with a high level of accuracy. The problems currently faced are the low reliability of responses of children, difficulties in cross-cultural comparison, and transformation of the sense of values according to growth. In conclusion, the development of QOL research in the field of child health should allow realization of an improved health situation in which children's points of view are included in the decision-making process for required treatments and health care policy.

    Full Text Available Jun Iwamoto1, Yoshihiro Sato2, Tsuyoshi Takeda1, Hideo Matsumoto21Department of Sports Medicine, Keio University School of Medicine, Tokyo, Japan; 2Department of Neurology, Mitate Hospital, Fukuoka, JapanAbstract: Osteoporosis most commonly affects postmenopausal women, placing them at a significant risk of fractures. In particular, hip fractures are an important cause of mortality and morbidity among postmenopausal women. Anti-resorptive therapies that produce greater decreases in bone turnover markers together with greater increases in bone mineral density (BMD are associated with greater reductions in fracture risk, especially at sites primarily composed of cortical bone such as the hip. Thus, treatment with potent anti-resorptive drugs like alendronate is a strategy for preventing hip fractures in postmenopausal women with osteoporosis. The purpose of this paper is to discuss the efficacy of alendronate against hip fractures and the mechanism for this anti-fracture efficacy in postmenopausal women with osteoporosis. A meta-analysis of randomized controlled trials has shown that alendronate reduces the risk of hip fractures by 55% in postmenopausal women with osteoporosis. According to the analyses of the Fracture Intervention Trial, each 1 standard deviation reduction in a 1-year change in bone-specific alkaline phosphatase (BSAP is associated with 39% fewer hip fractures in alendronate-treated postmenopausal women, and those with at least 30% reduction in BSAP have a 74% lower risk of hip fractures relative to those with less than 30%. Alendronate is effective in reducing the risk of hip fractures across a spectrum of ages. The mechanism for this anti-fracture efficacy has been clarified; alendronate strongly suppresses bone turnover and subsequently increases hip BMD, decreases cortical porosity, improves parameters of hip structure geometry (cortical thickness, cross-sectional area, section modulus, and buckling ratio, and produces more

    OBJECTIVE To assess the postoperative QOL(Quality of Life) of Chinese laryngeal cancer patients who have undergone a partial or total laryngectomy, and to analyze their prognostic factors, as well as to assess the feasibility of using the University of Washington Quality of Life (UW-QOL)questionnaire in QOL studies of laryngeal cancer patients.METHODS Using the UW-QOL questionnaire, a survey was conducted in patients treated by a partial or total laryngectomy for laryngeal cancer.RESULTS Questionnaires were sent to 142 patients who were diseasefree for more than half a year after surgery. Replies were received from130 patients (91% response rate) with 118 patients completing the questionnaire. These patients were divided into 2 groups: a partial-laryngectomy group (n=81; excluding cordectomy) and a total-laryngectomy group (n=37). The composite QOL scores of the partial-laryngectomy group (692.3 ±127.9) were higher than those of total-laryngectomy group(636.4±140.0), showing a statistically significant difference (P<0.05). The partial-laryngectomy group (74.3±23.8; 80.9±20.3) was better than the total-laryngectomy group (40.3±25.8; 69.6±27.1) in speech and appearance (P<0.001; P<0.05); but the total-laryngectomy group (92.6±13.0)was superior to the partial-laryngectomy group (83.0±20.5) in pain (P<0.01). Six factors including cancer stage, operative modality, complications, postoperative radiotherapy or chemotherapy, living partners and chronic disease before or after operation were related to postlaryngectomy QOL.CONCLUSION Partial laryngectomy is superior to total laryngectomy in speech, appearance and overall QOL. Besides operative modality, cancer stage, complications, postoperative radiotherapy or chemotherapy,living partners and chronic diseases before or after operation are factors influencing postlaryngectomy QOL. As a whole, the UW-QOL questionnaire is a good instrument for studying QOL of laryngeal cancer patients in China, and it can be

    Full Text Available Introduction: Osteoporosis which is primarily known as an adult disease may be encountered secondarily due to chronic diseases in children. Biphosphonates can be safely used in treatment with proven benefits. Alendronate is often preferred because of its advantage of oral use. Here, the efficiency and safety of alendronate in children with secondary osteoporosis were evaluated. Materials and Method: A total of 46 children (28 boys; 60.9% and 18 girls; 39.1% with secondary osteoporosis were included. Alendronate was given orally at a dose of 5 mg once daily for children less than 30 kg and 10 mg once daily for those weighing 30 kg or more. Bone mineral density (BMD was evaluated with DEXA taken at baseline, at 6th month, at 12th month and at 24th month. Results: Mean standard deviation scores (SDS of height, weight and body mass index were -2.43, -2.82 and -1.72, respectively. Serum Ca, P and ALP levels were all normal. Mean BMD SDS at baseline, 6th month, 12th month and 24th month were -4.03±0.96 -3.51±1.02, -2.82±1.09 and -2.43±0.93, respectively. Improvements in BMD z-scores at 6th, 12th and 24th months compared to baseline were all statistically significant.Conclusion: Our results showed that oral alendronate treatment which is more comfortable and cheaper than parenteral ones results in significant improvements in BMD, can be safely used and easily tolerated in children with secondary osteoporosis, as in adults. Though a plenty of studies were performed in children, there is still no consensus on the preferred and safe dose of the drug and the duration of treatment, as well as from the beginning of what age can the drug be introduced to the children requiring osteoporosis treatment.

Among the diagnostic techniques, functional images are the most sensitive in detecting osteomyelitis in its early stages. However, these techniques do not have adequate specificity. By contrast, radiolabeled antibiotics could improve selectivity, since they are specifically recognized by the bacteria. The incorporation of these radiopharmaceuticals in drug-delivery systems with high affinity for bones could improve the overall uptake. In this work, long-circulating and alendronate-coated liposomes containing 99mtechnetium-radiolabeled ceftizoxime were prepared and their ability to identify infectious foci (osteomyelitis in animal models was evaluated. The effect of the presence of PEGylated lipids and surface-attached alendronate was evaluated. The bone-targeted long-circulating liposomal 99mtechnetium–ceftizoxime showed higher uptake in regions of septic inflammation than did the non-long-circulating and/or alendronate-non-coated liposomes, showing that both the presence of PEGylated lipids and alendronate coating are important to optimize the bone targeting. Scintigraphic images of septic or aseptic inflammation-bearing Wistar rats, as well as healthy rats, were acquired at different time intervals after the intravenous administration of these liposomes. The target-to-non-target ratio proved to be significantly higher in the osteomyelitis

    In this article, the synthesis of a novel calcification-targeting nanoparticle (NP) is reported, which is realized through dopamine self-polymerization on the poly(lactic-co-glycolic acid) (PLGA) particle surface and subsequent alendronate conjugation. Cell viability and proliferation tests confirmed that such particle has low cytotoxicity and good biocompatibility. Experiments were designed to observe whether the synthesized NPs can pass through an obstructive hydrogel and directly bind themselves to hydroxyapatite (HA) NPs (mimicking calcified spots) and HA porous scaffolds (mimicking calcified tissues); and the result was positive, indicating ingenious targeting of NPs on calcifications. The calcification-targeting NPs are expected to be with promising applications on calcification-related disease diagnoses and therapies. PMID:26970822

    Alendronate (ALN) and risedronate (RIS) are ideal as first-choice therapy options in the treatment of postmenopausal osteoporosis. What to do for patients who do not respond adequately to bisphosphonates has not been conclusively determined, but transitioning to other therapies should be considered....... The aim of this article is to describe potential alternatives for patients switching from ALN or RIS to other therapies for osteoporosis. A systematic search of PubMed was conducted to find papers that evaluate the effects of switching therapies on fractures, bone mineral density (BMD), or bone...... turnover markers. Results from 11 studies that prospectively assessed treatment after ALN or RIS in women with postmenopausal osteoporosis were reviewed. All studies are of short duration (all 24 months or less) and assess the topic of transitioning therapy from ALN or RIS. None of the studies had the...

  4. The Quality of Life Scale (QOLS: Reliability, Validity, and Utilization

    2003-10-01

    Full Text Available Abstract The Quality of Life Scale (QOLS, created originally by American psychologist John Flanagan in the 1970's, has been adapted for use in chronic illness groups. This paper reviews the development and psychometric testing of the QOLS. A descriptive review of the published literature was undertaken and findings summarized in the frequently asked questions format. Reliability, content and construct validity testing has been performed on the QOLS and a number of translations have been made. The QOLS has low to moderate correlations with physical health status and disease measures. However, content validity analysis indicates that the instrument measures domains that diverse patient groups with chronic illness define as quality of life. The QOLS is a valid instrument for measuring quality of life across patient groups and cultures and is conceptually distinct from health status or other causal indicators of quality of life.

    Fukutin-related protein-muscular dystrophy is characterized by defects in glycosylation of α-dystroglycan with variable clinical phenotypes, most commonly as limb-girdle muscular dystrophy 2I. There is no effective therapy available. Glucocorticoid steroids have become the standard treatment for Duchenne and other muscular dystrophies with serious adverse effects, including excessive weight gain, immune suppression, and bone loss. Bisphosphonates have been used to treat Duchenne muscular dystrophy for prevention of osteoporosis. Herein, we evaluated prednisolone and alendronate for their therapeutic potential in the FKRPP448L-mutant mouse representing moderate limb-girdle muscular dystrophy 2I. Mice were treated with prednisolone, alendronate, and both in combination for up to 6 months. Prednisolone improved muscle pathology with significant reduction in muscle degeneration, but had no effect on serum creatine kinase levels and muscle strength. Alendronate treatment did not ameliorate muscle degeneration, but demonstrated a limited enhancement on muscle function test. Combined treatment of prednisolone and alendronate provided best improvement in muscle pathology with normalized fiber size distribution and significantly reduced serum creatine kinase levels, but had limited effect on muscle force generation. The use of alendronate significantly mitigated the bone loss. Prednisolone alone and in combination with alendronate enhance functionally glycosylated α-dystroglycan. These results, for the first time, demonstrate the efficacy and feasibility of this alliance treatment of the two drugs for fukutin-related protein-muscular dystrophy. PMID:27109613

    Highlights: ► The synthesized mesoporous hydroxyapatite has nanostructure and bioactivity. ► The materials have high surface area and amino group. ► The materials show higher drug loading and slower release rate than pure HAP. - Abstract: Mesoporous nanosized hydroxyapatite (HAP) functionalized by alendronate (ALN) was synthesized using cationic surfactant CTAB as template. The structural, morphological and textural properties were fully characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR) and N{sub 2} adsorption/desorption. Then the obtained materials were performed as drug delivery carriers using ibuprofen (IBU) as a model drug to investigate their drug storage/release properties in simulated body fluid (SBF). The materials showed relatively slower release rate compared with HAP due to the ionic interaction between -NH{sub 3}{sup +} on the matrix and -COO{sup −}belongs to IBU. The system provides a new concept for improving the drug loading or slowing down the release rate.

    This study compared the effects of extracorporeal shock wave therapy (ESWT) and alendronate sodium (alendronate) in osteoarthritis (OA) of rat knees. The control group was subjected to a sham surgery and did not receive either ESWT or alendronate treatment. The OA group underwent anterior cruciate ligament transection (ACLT) and medial meniscectomy (MM) surgery and did not receive either ESWT or alendronate. The ESWT group underwent ACLT and MM surgery and received ESWT after the surgery. The alendronate group received alendronate after ACLT and MM surgery. The evaluations included radiograph, bone mineral density (BMD), serum C-telopeptide collagen II (CTX-II), cartilage oligomeric protein (COMP), alkaline phosphatase and osteocalcin, histopathological examination and immunohistochemical analysis. Radiographs at 12 weeks showed pronounced OA changes in the OA group. The BMD values, CTX-II, COMP, alkaline phosphatase and osteocalcin showed no significant difference between ESWT and alendronate groups. In histopathology, the Mankin and Safranin O scores significantly increased in the OA, ESWT and alendronate groups, but without any significant difference between the ESWT and alendronate groups. In immunohistochemical analysis, the von Willebrand factor (vWF), vascular endothelial factor (VEGF), soluble vascular cell adhesion molecule (sVCAM), proliferating cell nuclear antigen (PCNA), bone morphogenetic protein 2 (BMP-2), and osteocalcin expressions in articular cartilage and subchondral bone showed a significant decrease in the OA group, but no difference was noted between the ESWT and alendronate groups. In conclusion, ESWT and alendronate sodium demonstrate equal protective effects from developing osteoarthritis of the knee in rats.

    2010-10-01

    Full Text Available This paper reports a biological evaluation of a non-resorbable acrylic cement loaded with alendronate for the treatment of osteoporotic vertebral compression fractures. The cement formulation was based on polymethyl methacrylate and acrylic monomers; one of these had covalently linked vitamin E residues. The same cement in the absence of alendronate was used as a control. The setting of the charged cement presented a maximum polymerization temperature of 44ºC, a setting time of 24 min, a residual monomer content lower than 3 wt.%, a compressive strength of 99±10 MPa and an elastic modulus of 1.2±0.2 GPa. Cytotoxicity studies using human osteoblast cultures revealed that the leachable substances of the alendronate loaded cement collected between 1 and 7 days decreased cell viability to values lower than 80%. However, morphological changes and cellular damage in cells produced by the extracts decreased with the leak time. Cell adhesion and growth on charged cement was significantly lower than on the control. Implantation of the cement paste in the intra-femoral cavity of rabbits showed that initially the osteogenic activity was evident for the cement charged with alendronate, and the osteosynthesis process took place mainly in the trabeculae and was manifested by the presence of a non-mineralised osseous spicule. The interface between material and adjacent bone tissue was initially characterized by a variable fibrous response that in many cases it appeared reduced to thin connective tissue after a 24-week-period.

    In this study, the characteristics of the alveolar bone of rats with induced osteoporosis were examined. Thirty-two rats were divided into four groups according to the induction of osteoporosis and drugs administered: OG, osteoporotic rats without treatment (negative control); SG, rats which underwent sham surgery ovariectomy (SHAM); alendronate (AG), osteoporotic rats treated with alendronate; and RG, osteoporotic rats treated with raloxifene (RG). On the 8th day after ovariectomy and SHAM surgeries, drug therapy was started with AG or RG. On the 52nd day, 20 mg/kg calcein was administered to all of the rats, and on the 80th day, 20 mg/kg alizarin red was administered. Euthanasia was performed on the 98th day. The bone area marked by fluorochromes was calculated and data were subjected to two-way ANOVA test and Tukey's post-hoc test (p<0.05). The comparison of the induced osteoporosis groups showed no statistically significant differences in bone turnover only between RG and SG (p=0.074) and AG and OG (p=0.138). All other comparisons showed significant differences (p<0.001). The largest bone turnover was observed in RG and SG groups. RG was the medication that improved the dynamics of the alveolar bone of rats with induced osteoporosis, resembling that of healthy rats.

    Full Text Available ABSTRACT INTRODUCTION: Rhinosinusitis constitutes an important health problem, with significant interference in personal, professional, and social functioning. This study presents the validation process of the Portuguese version of the RhinoQOL, to be used as a routine procedure in the assessment of patients with chronic rhinosinusitis. OBJECTIVE: To demonstrate that the Portuguese version of the RhinoQOL is as valid as the English version to measure symptoms and health-related quality of life in chronic rhinosinusitis. METHODS: The Portuguese version of the RhinoQOL was administered consecutively to 58 patients with chronic rhinosinusitis with and without nasal polyps, assessed for endoscopic sinus surgery. A follow-up survey was completed three months after surgery. Statistical analysis was performed to determine its psychometric properties. RESULTS: Face and content validity were confirmed by similar internal consistency as the original questionnaire for each sub-scale, and strong correlation between individual items and total score. The questionnaire was easy and quick to administer (5.5 min. At three months, there was a significant decrease from baseline for all sub-scale scores, indicating clinical improvement, with an effect size considered as large. CONCLUSION: This study provides a questionnaire that is equivalent to the original English version, with good responsiveness to change, which can be especially valuable to measure the outcome of surgery.

    Background Alendronate, a nitrogen-containing bisphosphonate is a specific inhibitor of bone resorption and now in the forefront of treatment of osteoporosis. In this study, we reported a significant increase in bone mineral density (BMD) of the spine and the hip in postmenopausal women taking alendronate at 10 mg/d for 1, 2 and 3 years. Methods Participants had received daily, oral, 10 mg dose of alendronate for one to three years and placed into one of three groups according to alendronate treatment duration: 41 women received alendronate for 1 year (group Ⅰ), 46 received alendronate for 2 years (group Ⅱ), and 30 received alendronate for 3 years (group Ⅲ). Measurements of bone density had been made by dual energy X-ray absorbtiometry once each year. Results The differences in L2-L4, L2, L4, femoral neck and trochanter BMD values before and after treatment for first group were significantly different. In second group, significant differences between initial and after treatment were found at the other sites except at the Ward's triangle. In the third group, only a significant increase in the L2-L4, L2, L3, L4, trochanter BMD values between before treatment and at the end of third year was found. Comparisons between groups were performed with Student's t test. ANOVA was used to test the age, menopause age, menopause duration and initial BMD values between the three groups. Calculated P values of less than 0.05 were considered statistically significant. Conclusions Alendronate had increased BMD significantly at the spine and hip in postmenopausal women over three years. Increases of BMD in third group were significant during the first and second years. However, continued therapy with alendronate had been required to maintain the gain in BMD over the third year.

    The objective of this study was to measure the impact of edentulism and dental prostheses on quality of life (QOL) in older adults in Bogota, Colombia. Edentulism is a frequent condition in older adults and has great impact on their QOL. No epidemiological data are currently available on edentulism among older adults in Colombia. Data were obtained from the SABE-Bogota study, a cross-sectional study conducted in 2012, and used to analyze the EQ-VAS (Visual Analog Scale) from the EuroQol instrument to measure the perception of quality of life (QOL) in relation to edentulism. The study included 2,000 individuals over 60 years old. The Spearman-Rho correlation was used to analyze the correlation between EQ-VAS and edentulism. Chi-Square, ANOVA and t-test were used to study the differences in EQ-VAS scores between edentulous and healthy subjects. Statistical significance was set at psocial class and lower education were related to edentulism. Individuals with fewer teeth and dental prostheses had lower EQ-VAS scores (paffects QOL in older adults and the use of dental prosthesis does not improve the perception of QOL. PMID:26355885

Though fracture risk is lowered, an increase in microdamage accumulation has been documented in patients receiving alendronate, leading to questions about the potentially detrimental effects of remodeling suppression on the local tissue (material) properties. In this study, trabecular bone cores from the distal femur of beagle dogs treated for one year with alendronate, at doses scaled by weight to approximate osteoporotic and Paget's disease treatment doses in humans, were subjected to uniaxial compression to induce microdamage. Tissue level von Mises stresses were computed for alendronate-treated and non-treated controls using finite element analysis and correlated to microdamage morphology. Using a modified version of the Moore and Gibson classification for damage morphology, we determined that the von Mises stress for trabeculae exhibiting severe and linear microcrack patterns was decreased by approximately 25% in samples treated with alendronate compared with non-treated controls (pbone's architecture and matrix properties associated with one year of alendronate administration reduce trabecular bone's ability to resist the formation of loading-induced severe and linear microcracks, both of which dissipate less energy prior to fracture than does diffuse damage.

    Precise techniques for the measurement of maxillary bone mineral density (BMD) are useful for the early diagnosis of systemic diseases. The aim of this study was to compare in vivo the efficacy of dual energy x-ray absorptiometry (DXA) and radiographic densitometry for the measurement of BMD after systemic administration of sodium alendronate. Wistar rats were randomly allocated to a control group (n = 5), which received distilled water, and a sodium alendronate group (n = 8), which received two doses of chemically pure sodium alendronate (1 mg/kg) per week. After 8 weeks, the animals were euthanized, the tibias were removed, and the BMD of the proximal tibial metaphysis was analyzed radiographically and by DXA. The data were subjected to statistical analysis by the Kruskal-Wallis test at a significance level of 5%. Both of the techniques revealed that the alendronate-treated group had a significantly higher BMD (p < 0.05) than the control group after 8 weeks of treatment. Comparing the groups with and without alendronate therapy revealed increases of 14.9% and 29.6% in BMD, as detected radiographically and by DXA, respectively. In conclusion, both of the methods were able to detect an increase in BMD of the proximal tibial metaphysis after alendronate therapy. (author)

  8. Effects of radiotherapy for brain metastases on quality of life (QoL). Prospective pilot study of the DEGRO QoL working party

    International Nuclear Information System (INIS)

    Background: Prospective data on quality-of-life (QoL) effects of radiotherapy for brain metastases are currently lacking, but would be of great interest to guide therapeutic decisions. Patients and Methods: From 01/2007 to 08/2007, 46 patients with previously untreated brain metastases were recruited at eight centers. QoL was measured at start of treatment (T0) and at 3 months (T3mo). In the pilot study, two combinations of QoL instruments could be used at the discretion of the centers (A: EORTC QLQ-C30 and B: EORTC QLQ-C15-PAL both with brain module BN20, assessment by proxies with A: Palliative Care Outcome Scale, B: self-constructed brain-specific instrument). Results: All patients received whole-brain radiotherapy, four with an additional boost irradiation. At T3mo, 26/46 patients (56.5%) had died. 17/20 survivors (85%) completed the questionnaires. In 3-month survivors, QoL deteriorated in most domains, significant in drowsiness, hair loss and weakness of legs. The scores for headaches and seizures were slightly better after 3 months. Assessment by proxies also suggested worsening of QoL. Initial QoL at T0 was better in those alive than in those deceased at T3mo, significant for physical function and for the symptom scales of fatigue and pain, motor dysfunction, communication deficit and weakness of legs. Conclusion: Practicability and compliance appeared better with the (shorter) version B. This version is now used in the ongoing main phase of the study with additional centers. First results indicate a moderate worsening of QoL during the first 3 months after start of palliative radiotherapy for brain metastases. QoL at initiation of radiotherapy may be prognostic for survival. (orig.)

    We aimed to characterize incident users of alendronate from Denmark and Spain, and investigate their eligibility for participation in the pivotal Fracture Intervention Trial (FIT). This is an international cross-sectional study, where the data were obtained from the SIDIAP database (Sistema d'Informació per al Desenvolupament de l'Investigació en Atenció Primària) from Catalonia (Spain) and the Danish Health Registries (DHR). This study included patients who were incident users of alendronate, ≥40 years old with no history of Paget's disease. Our measurements were the proportion of incident users of alendronate who were not eligible to participate in FIT. 14,316 and 21,221 subjects initiated alendronate in 2006-2007 (SIDIAP) and 2005-2006 (DHR), respectively. SIDIAP and DHR alendronate user cohorts had 2347 (16.4 %) and 5275 (24.9 %) subjects aged >80 years old, reported 9 (0.1 %) and 91 (0.4 %) diagnoses of myocardial infarction, 423 (3 %) and 368 (1.7 %) of erosive gastro-intestinal disease, 200 (1.4 %) and 1109 (5.2 %) of dyspepsia, and 349 (2.4 %) and 149 (0.7 %) of metabolic bone disease, all of which were exclusion criteria in FIT. Men [3818 (26.7 %) in SIDIAP and 3885 (18.3 %) in DHR] and glucocorticoid users [1229 (8.6 %) in SIDIAP and 4716 (22.2 %) in DHR] were also excluded from the FIT trial. Overall, 3447 (35.4 %) SIDIAP and 6228 (44.5 %) (when not considering men and glucocorticoid users) DHR of incident alendronate users would have been excluded from FIT. One in two real-life users of alendronate exhibited one or more clinical characteristics that would have led to them being excluded from the FIT trial. PMID:27099132

    2014-03-01

    Full Text Available Introduction: Alendronate sodium enhances bone formation and increases osteoblast proliferation and maturation and leads to the inhibition of osteoblast apoptosis. Therefore, a rapid and simple spectrofluorometric method has been developed and validated for the quantitative determination of it. Methods: The procedure is based on the reaction of primary amino group of alendronate with o-phthalaldehyde (OPA in sodium hydroxide solution. Results: The calibration graph was linear over the concentration range of 0.0-2.4 μM and limit of detection and limit of quantification of the method was 8.89 and 29 nanomolar, respectively.The enthalpy and entropy of the reaction between alendronate sodium and OPA showed that the reaction is endothermic and entropy favored (ΔH = 154.08 kJ/mol; ΔS = 567.36 J/mol K which indicates that OPA interaction with alendronate is increased at elevated temperature. Conclusion: This simple method can be used as a practical technique for the analysis of alendronate in various samples.

    Full Text Available OBJECTIVE: To evaluate the effect of two different concentrations of sodium alendronate on the quantity of organic matrix in the femur of rats with estrogen suppression caused by ovariectomy.METHODS: Sixty-days-old Wistar rats (Rattus norvegicus were subjected to bilateral laparotomy to remove the ovaries. The animals were divided into a control group, in which they only underwent laparotomy; an ovariectomized group (OVX; an ovariectomized group treated with 1 mg/kg of alendronate (OVX 1 mg; and an ovariectomized group treated with 2 mg/kg of alendronate (OVX 2 mg. The rats received alendronate twice a week for 90 days. The left femur was then removed, fixed and processed for embedding in paraffin. Semi-serial sections stained with hematoxylin and eosin were used to determine the area occupied by organic bone matrix, by means of image analysis software. The animals' weights were obtained at the beginning and end of the experiment.RESULTS: The ovariectomized animals and those treated with 1 mg/kg of alendronate presented significant increases in body weight (p 0.05 to that of the non-ovariectomized control animals (2,04,800 ± 9590, which indicates that this medication had a preventive effect with regard to bone mass loss.CONCLUSION: The higher concentration of the medication, administered twice a week for 90 days, was more effective than the dose of 1 mg/kg over the same period.

    Loss of bone mass during periods of skeletal unloading remains an important clinical problem. To determine the extent to which resorption contributes to the relative loss of bone during skeletal unloading of the growing rat and to explore potential means of preventing such bone loss, 0.1 mg P/kg alendronate was administered to rats before unloading of the hindquarters. Skeletal unloading markedly reduced the normal increase in tibial mass and calcium content during the 9 day period of observation, primarily by decreasing bone formation, although bone resorption was also modestly stimulated. Alendronate not only prevented the relative loss of skeletal mass during unloading but led to a dramatic increase in calcified tissue in the proximal tibia compared with the vehicle-treated unloaded or normally loaded controls. Bone formation, however, assessed both by tetracycline labeling and by [3H]proline and 45Ca incorporation, was suppressed by alendronate treatment and further decreased by skeletal unloading. Total osteoclast number increased in alendronate-treated animals, but values were similar to those in controls when corrected for the increased bone area. However, the osteoclasts had poorly developed brush borders and appeared not to engage the bone surface when examined at the ultrastructural level. We conclude that alendronate prevents the relative loss of mineralized tissue in growing rats subjected to skeletal unloading, but it does so primarily by inhibiting the resorption of the primary and secondary spongiosa, leading to altered bone modeling in the metaphysis.

  16. Measurement of Quality of Life IV. Use of the SEQOL, QOL5, QOL1, and Other Global and Generic Questionnaires

    2003-01-01

    Full Text Available Quality-of-life (QOL rating scales can be used to measure and describe the quality of life of a specific population or patient group. Many decisions can be taken and policies implemented when we know more about a group or population. The global quality-of-life concept may help in expressing the objective of the initiatives taken to benefit specific groups. The objective may be that we hope the efforts will increase their quality of life by a certain percentage. This explicit expectation will force the decision makers to stand by their noble intentions. They are obliged to evaluate their efforts and will have to learn something from it.A questionnaire thus constitutes a useful scientific instrument, as databases based on comprehensive and thorough questionnaire surveys that seek to encompass all aspects of life can provide valuable and precise information. The value of such a database depends on the correct use of the questionnaires and this paper examines some examples of how quality-of-life rating scales can be used.We identified at least ten ways to use the quality-of-life questionnaire: describing the quality of life of a population or patient group; formulating an objective for support, treatment, or care; screening or identifying individuals who need treatment; evaluating treatment and care; facilitating communication between physician and patients; involving the patient in the decision-making process; allocating resources; investigating the causal relation between the quality of life and ill health in prospective studies; creating an awareness of the quality of life and health promotion; and helping the practitioner to accumulate knowledge.Enhancing the quality of life is therefore a determining factor in the process of increasing awareness and responsible conduct in relation to the environment, natural resources, the working environment, and the structure of society. Putting the quality of life on the agenda inherently has a constructive

    Development of biomimetic scaffolds represents a promising direction in bone tissue engineering. In this study, we designed a two-step process to prepare a type of biomimetic hybrid hydrogels that were composed of collagen, hydroxyapatite (HAP) and alendronate (ALN), an anti-osteoporosis drug. First, water-soluble ALN-conjugated HAP (HAP-ALN) containing 4.0wt.% of ALN was synthesized by treating HAP particles with ALN. Hydrogels were then formed from HAP-ALN conjugate and collagen under physiological conditions using genipin (GNP) as the crosslinker. Depending on the ALN/collagen molar ratio and GNP concentration, the gelation time of hydrogels ranged from 5 to 37min. Notably, these hybrid hydrogels exhibited markedly improved mechanical property (storage modulus G'=38-187kPa), higher gel contents, and lower swelling ratios compared to the hydrogels prepared from collagen alone under similar conditions. Moreover, they showed tunable degradation behaviors against collagenase. The collagen/HAP-ALN hybrid hydrogels supported the adhesion and growth of murine MC3T3-E1 osteoblastic cells well. Such tough yet enzymatically degradable hybrid hydrogels hold potential as scaffolds for bone tissue engineering. PMID:26998869

  18. Alendronate reduced peri-tunnel bone loss and enhanced tendon graft to bone tunnel healing in anterior cruciate ligament reconstruction

    2013-01-01

    Full Text Available Peri-tunnel bone loss after anterior cruciate ligament (ACL reconstruction is commonly observed, both clinically and experimentally. We aimed to study the effect and mechanisms of different doses of alendronate in the reduction of peri-tunnel bone loss and promotion of graft-bone tunnel healing in ACL reconstruction. Eighty-four ACL-reconstructed rats were divided into 4 groups. Alendronate at different dosages, or saline, were injected subcutaneously weekly, for 2 or 6 weeks post-reconstruction, for vivaCT (computed tomography imaging, biomechanical tests, histology and immunohistochemistry. Alendronate significantly increased bone mass and density of tissue inside bone tunnels except at the epiphyseal region of tibial tunnel. The femoral tunnel diameter decreased significantly in the mid-dose and high-dose alendronate groups compared to that in the saline group at week 6. Alendronate significantly increased the peri-tunnel bone mass and density along all tunnel regions at week 6. Better graft-bone tunnel integration and intra-tunnel graft integrity were observed in the alendronate groups. The ultimate load was significantly higher in the mid-dose and high-dose alendronate groups at week 2, but not at week 6. There was a reduction in matrix metalloprotein (MMP1, MMP13 and CD68-positive cells at the peri-tunnel region and graft-bone interface in the alendronate-treated group compared to the saline group. Alendronate reduced peri-tunnel bone resorption, increased mineralised tissue inside bone tunnel as well as histologically and biomechanically promoted graft-bone tunnel healing, probably by reducing the expression of MMP1, MMP13 and CD68-positive cells. Alendronate might be used for reducing peri-tunnel bone loss and promoting graft-bone tunnel healing at early stage post-ACL reconstruction.

    Full Text Available The hydrophilic drug sodium alendronate was encapsulated in blended microparticles of Eudragit® S100 and Methocel® F4M or Methocel® K100LV. Both formulations prepared by spray-drying showed spherical collapsed shape and smooth surface, encapsulation efficiencies of 85 and 82% and mean diameters of 11.7 and 8.4 µm, respectively. At pH 1.2, in vitro dissolution studies showed good gastro-resistance for both formulations. At pH 6.8, the sodium alendronate release from the microparticles was delayed and was controlled by Fickian diffusion. In conclusion, the prepared microparticles showed high encapsulation efficiency of sodium alendronate presenting gastro-resistance and sustained release suitable for its oral administration.

  2. Metallic stents provide better QOL than plastic stents in patients with stricture of unresectable advanced esophageal cancer

    International Nuclear Information System (INIS)

    The aim of this study was to elucidate the utility and safety of treatment with esophageal stents (plastic and metallic stents) for unresectable advanced esophageal cancer. Between 1992 and 2002, 14 cases of unresectable advanced esophageal cancer were treated with esophageal stents (the plastic stent group, 7 cases; and the metallic stent group, 7 cases). Of these, 10 cases had a history of chemotherapy and or radiotherapy. An improvement in oral intake and performance status (PS), survival time, periods at home, and adverse events were compared between the two groups. After stenting, oral intake and PS were significantly improved in the metallic stent group. Follow-up at home was possible in 71.4%. There was no significant difference in survival or duration of time at home between the two groups. All adverse events were controllable and there was no difference between the two groups. Stenting not only improved oral intake and PS but also allowed a stay at home, resulting in a marked improvement in patients' quality of life (QOL). Stenting was performed safely even in cases with a history of radiotherapy. There was no difference in survival, ratios of staying at home, and safety between the two groups, but QOL was significantly improved in the metallic stent group. These outcomes indicate that placement of metallic stents should be actively considered to treat stricture due to advanced esophageal cancer. (author)

    Full Text Available Sodium alendronate is an antiresorptive drug used for the treatment of postmenopausal osteoporosis. However, its oral administration is associated with low bioavailability and gastroesophageal irritation. This work aimed at developing tablets containing sodium alendronate-loaded microparticles by direct compression to achieve a safe and effective form. The parameters evaluated were average weight, hardness, thickness and drug content. In vitro release tests were carried out using simulated gastric and intestinal fluids, and the profiles were analyzed through the Korsmeyer-Peppas mono- or biexponential dependent approaches. Tablets presented adequate average weight, thickness, good mechanical properties and drug content close to 100%. Moreover, the formulation released less than 11% of sodium alendronate in gastric fluid, exhibiting a good gastroresistance. At pH 6.8, almost 100% of the drug was released in 12h, showing a prolonged profile. The mathematical modeling indicated that the experimental data was better fitted to the biexponential equation. Furthermore, a good correlation coefficient was obtained for the Korsmeyer-Peppas model and the release exponent suggested that the drug dissolution was driven by anomalous transport. In conclusion, the microparticulated tablets can be considered a promising alternative for oral delivery of sodium alendronate.

    This study investigated the healing potential of allograft from bisphosphonate-treated animals in anterior lumbar spine interbody fusion. Three levels of anterior lumbar interbody fusion with Brantigan cages were performed in two groups of five landrace pigs. Empty Brantigan cages or cages filled with either autograft or allograft were located randomly at different levels. The allograft materials for the treatment group were taken from the pigs that had been fed with alendronate, 10 mg daily for 3 months. The histological fusion rate was 2/5 in alendronate-treated allograft and 3/5 in non-treated allograft. The mean bone volume was 39% and 37.2% in alendronate-treated or non-treated allograft (NS), respectively. No statistical difference was found between the same grafted cage comparing two groups. The histological fusion rate was 7/10 in all autograft cage levels and 5/10 in combined allograft cage levels. No fusion was found at all in empty cage levels. With the numbers available, no statistically significant difference was found in histological fusion between autograft and allograft applications. There was a significant difference of mean bone volume between autograft (49.2%) and empty cage (27.5%) (P<0.01). In conclusion, this study did not demonstrate different healing properties of alendronate-treated and non-treated allograft for anterior lumbar interbody fusion in pigs. PMID:15248057

    Cognitive impairment after stroke has a direct impact on daily functioning and quality of life (QoL) of patients and is associated with higher mortality and healthcare costs. The aim of this study was to determine the effect of a computer-based brain training programme on cognitive functioning, QoL and self-efficacy compared to a control condition in stroke patients. Stroke patients with self-perceived cognitive impairment were randomly allocated to the intervention or control group. The intervention consisted of an 8-week brain training programme (Lumosity Inc.®). The control group received general information about the brain weekly. Assessments consisted of a set of neuropsychological tests and questionnaires. In addition, adherence with trained computer tasks was recorded. No effect of the training was found on cognitive functioning, QoL or self-efficacy when compared to the control condition, except for very limited effects on working memory and speed. This study found very limited effects on neuropsychological tests that were closely related to trained computer tasks, but no transfers to other tests or self-perceived cognitive failures, QoL or self-efficacy. These findings warrant the need for further research into the value of computer-based brain training to improve cognitive functioning in the chronic phase after stroke. PMID:27184585

    Treatment of osteoporosis with alendronate sodium has several challenges. The first challenge is the low bioavailability. The second main challenge is side effects, which include oesophageal ulceration. The aim of this research was to reformulate alendronate sodium as enteric coated solid lipid nanoparticles in order to enhance its bioavailability, and preventing the free alendronate sodium from coming into direct contact with the gastrointestinal mucosa, and thereby reducing the possibility of side effects. Enteric coated solid lipid nanoparticles were prepared according to the Box-Behnken design employing Design expert® software, and characterized for size, morphology, and entrapment efficiency. The optimized formula was coated with an Eudragit S100 and evaluated for drug release in acidic and basic media, stability studies and pharmacokinetic evaluations on rabbits. The results indicated that, using Derringer's desirability functional tool for optimization, the highest entrapment efficiency value of 74.3% and the smallest size value of 98 nm were predicted under optimum conditions with a desirability value of 0.917. The optimized nanoparticles released alendronate sodium only at an alkaline pH. The pharmacokinetic evaluation revealed that alendronate sodium bioavailability was enhanced by more than 7.4-fold in rabbits. In conclusion, enteric coated solid lipid nanoparticles is a promising formula for the delivery of alendronate sodium, eliminating its oesophageal side effects and enhancing its bioavailability.

    In this study, we sought to explore the prevalence of depression and fatigue in colorectal cancer patients during and after treatment to examine how these variables affect quality of life (QoL). In total, 170 patients with colorectal cancer participated in this study. The study population was divided into two groups: one receiving treatment and another that had finished treatment. The results showed that depression and fatigue measurements were higher in patients receiving treatment. Depression was a strong and significant predictor of QoL in both groups, whereas fatigue was not, with the exception of the symptom score. These findings underscore the importance of early detection and management of depression and fatigue during the treatment and survival stages of patients with colorectal cancer. Our findings indicate that health care professionals should provide appropriate nursing intervention to decrease depression and fatigue and enhance patient QoL. PMID:26902798

    We measured intracellular cAMP levels in cells during attachment and spreading on different extracellular matrix (ECM) proteins. Increases in cAMP were observed within minutes when cells attached to fibronectin, vitronectin, and a synthetic RGD-containing fibronectin peptide (Petite 2000), but not when they adhered to another integrin alpha nu beta 3 ligand, echistatin. Because echistatin also inhibits bone resorption, we measured the effects of adding another osteoporosis inhibitor, alendronate, in this system. Alendronate inhibited the cAMP increase induced by ligands that primarily utilize integrin alpha nu beta 3 (vitronectin, Peptite 2000), but not by fibronectin which can also use integrin alpha 5 beta 1. These results show that cell adhesion to ECM can increase intracellular cAPM levels and raise the possibility that inhibitors of osteoporosis may act, in part, by preventing activation of this pathway by integrins.

    could be present. Objective — Report a case of a patient who underwent total gastrectomy with Y-en-Roux anastomosis for a gastric carcinoid tumor and developed an esophagus-enteric anastomosis ulceration after the use of alendronate. Patient and Method — A 63-year-old woman started medical therapy with alendronate in a dose of 10 mg daily. After a period of one month of medical treatment with this drug she began to complain of dysphagic symptoms and abdominal pain. She was submitted to endoscopic examination that showed an esophageal ulceration, an enteric ulceration of the anastomosis and an esophageal stenosis. Results - Medical treatment with alendronate was discontinued and the symptom of abdominal pain desapeared. The intensity of dysphagia has decreased. The ulcerated lesion remitted although esophageal stenosis did not. The patient was subsequently treated with esophagus-enteric anastomosis dilation. She improved in her general state and nowadays she is free of symptoms. Conclusion — Alendronate sodium could cause lesions of the inferior esophageal portion or in distal segments of the gastrointestinal tube, in patients with a fast gastrointestinal transit. Special attention must be given to gastrectomized patients that use this drug because of the possibility to develop mucosal lesions in the enteric anastomosed part and its fearfull complications as stenosis.

    The National Institute for Health and Clinical Excellence (NICE) in the UK has recently issued health economic appraisals for the primary and secondary prevention of osteoporotic fracture that are more restrictive than previous guidelines for the management of osteoporosis despite a marked reduction of the cost of intervention. The aim of the present study was to examine the cost-effectiveness of the bisphosphonate, alendronate for the prevention and treatment of fractures associated with osteoporosis. A second aim was to investigate reasons for any disparities in cost-effectiveness between our findings and the NICE appraisals. We compared the effects of alendronate 70 mg weekly by mouth for 5 years with no treatment in postmenopausal women with clinical risk factors for fracture and computed the incremental cost-effectiveness ratio (ICER) using a lifetime simulation model based on Markov cohort methodology. A sensitivity analysis examined other common interventions. Using a threshold of pound sterling 30,000 and pound sterling 20,000 per quality of life-year (QALY) gained to determine cost-effectiveness, alendronate was cost-effective for the primary prevention of fracture in women with osteoporosis irrespective of age as was treatment of women with a prior fragility fracture irrespective of BMD. Cost-effective scenarios were also found in women with strong risk factors for fracture with a bone mineral density value above the threshold for osteoporosis. The results were robust over reasonable assumptions in sensitivity analysis. We conclude that alendronate is a cost-effective agent for the prevention and treatment of fractures associated with osteoporosis. These findings, suitable for informing practice guidance, contrast with recent appraisals from NICE. PMID:18156107

    Alendronate belongs to a class of drugs called bisphosphonates. Bisphosphonates (BP) therapy is a vital option to reduce the risk of bone fracture in people who suffer from osteoporosis. Yet, bisphosphonate have displayed several side effects. Lepidium sativum (LS) seeds have been used in traditional folk medicine to heal fractured bones. However, there is a dearth of information on the impact of LS on bone metabolism especially in cases of glucocorticoids induced osteoporosis. Therefore, the...

  2. Effect of alendronate on endochondral ossification in mandibular condyles of growing rats

    2012-05-01

    Full Text Available The replacement of the calcified cartilage by bone tissue during the endochondral ossification of the mandibular condyle is dependent of the resorbing activity of osteoclats. After partial resorption, calcified cartilage septa are covered by a primary bone matrix secreted by osteoblasts. Osteoadherin (OSAD is a small proteoglycan present in bone matrix but absent in cartilage during the endochondral ossification. The aim of this study was to analyze the effect of alendronate, a drug known to inhibit bone resorption by osteoclasts, on the endochondral ossification of the mandibular condyle of young rats, by evaluating the distribution of osteoclasts and the presence of OSAD in the bone matrix deposited. Wistar newborn rats (n=45 received daily injections of alendronate (n=27 or sterile saline solution as control (n=18 from the day of birth until the ages of 4, 14 and 30 days. At the days mentioned, the mandibular condyles were collected and processed for transmission electron microscopy analysis. Specimens were also submitted to tartrate resistant acid phosphatase (TRAP histochemistry and ultrastructural immunodetection of OSAD. Alendronate treatment did not impede the recruitment and fusion of osteoclasts at the ossification zone during condyle growth, but they presented inactivated phenotype. The trabeculae at the ossification area consisted of cartilage matrix covered by a layer of primary bone matrix that was immunopositive to OSAD at all time points studied. Apparently, alendronate impeded the removal of calcified cartilage and maturation of bone trabeculae in the mandibular ramus, while in controls they occurred normally. These findings highlight for giving attention to the potential side-effects of bisphosphonates administered to young patients once it may represent a risk of disturbing maxillofacial development.

    Odanacatib (ODN) is a bone resorption inhibitor which differs from standard antiresorptives by its ability to reduce bone resorption without decreasing bone formation. What is the reason for this difference? In contrast with other antiresorptives, such as alendronate (ALN), ODN targets only the very last step of the resorption process. We hypothesize that ODN may therefore modify the remodeling events immediately following osteoclastic resorption. These events belong to the reversal phase and...

  7. Effect of alendronate on skeletal uptake of technetium-99m MDP in a rat model

    International Nuclear Information System (INIS)

    Full text: Bisphosphonate compounds are now commonly used in the treatment of osteoporosis and their use is increasing in both myeloma and breast cancer patients. Whether bisphosphonates interfere with the uptake of bone seeking radiopharmaceuticals which have a similar chemical structure remains controversial. The effect of Alendronate on the uptake of methylene diphosphonate (MDP) was assessed in a group of 20 Wistar rats; 10 were given oral Alendronate approximately 1mg/kg/day for seven days against 10 controls. Four MBq 99Tcm-MDP was administered into a central vein under barbiturate anaesthesia. Four hours later samples of blood, thigh muscle and both femurs were obtained. These samples were weighed and the activity measured using a gamma counter then expressed as percent dose per gram of tissue. Mean activity, standard deviation and statistical significance were calculated for the blood, muscle and femurs. No significant difference was present in femoral activity, on comparison of the test and control groups at a significance level of 5%. In conclusion, oral Alendronate administration does not cause a significant reduction in the skeletal uptake of 99Tcm-MDP in rats, based on the sample size and dose used. A further 20 animals will be studied using a higher test dose of approximately 5mg/kg/day. Copyright (2000) The Australian and New Zealand Society of Nuclear Medicine Inc

  14. Production, quality control, biodistribution assessment and preliminary dose evaluation of 166Ho-alendronate as a bone marrow ablative agent

    International Nuclear Information System (INIS)

    In this study, production, quality control and biodistribution studies of 166Ho-alendronate have been presented and followed by dosimetric evaluation for human based on biodistribution data in wild-type rats. 166Ho chloride was obtained by thermal neutron irradiation of natural 165Ho(NO3)3 samples. 166Ho-alendronate complex was prepared by adding the desired amount of alkaline alendronate solution (0.2 mL, 150 mg/mL) to 3-5 mCi of the 166HoCl3 solution. Radiochemical purity of the complex was monitored by instant thin layer chromatography (ITLC). 166Ho-alendronate complex was prepared in high radiochemical purity (> 99%, ITLC) and specific activity of 4.4 GBq/mmol. Stability studies of the complex in the final preparation and in the presence of human serum were performed up to 48 h. The major accumulation of the radio-complex was in the bone tissues followed by absorbed dose evaluation of each human organ by RADAR software used for modelling the radiation dose delivered. The final preparation was administered to wild-type rats and biodistribution of the complex was performed 2-48 h post injection showing major accumulation of the complex in the bone tissue. The highest absorbed dose for 166Ho-alendronate is observed in bone surface and red marrow with 2.670 and 1.880 mSv/MBq; respectively. These findings suggest that 166Ho-alendronate has considerable characteristics compared to 166Ho-DOTMP and can be a possible candidate for bone marrow ablation in patients with multiple myeloma.

    Full Text Available Due to their well-established fracture risk reduction, bisphosphonates are the most frequently used therapeutic agent to treat osteoporosis. Bisphosphonates reduce fracture risk by suppressing bone resorption, but the lower bone turnover could have a negative impact on bone quality at the tissue level. Here, we directly assess the structural and mechanical characteristics of cancellous bone from the lumbar vertebrae (L5 in non-treated osteoporotic controls (n = 21, mid-term alendronate-treated osteoporotic patients (n = 6, and long-term alendronate-treated osteoporotic patients (n = 7. The strength and toughness of single trabeculae were evaluated, while the structure was characterised through measurements of microdamage accumulation, mineralisation distribution, and histological indices. The alendronate-treated cases had a reduced eroded surface (ES/BS, p < 0.001 and a higher bone mineralisation in comparison to non-treated controls (p = 0.037, which is indicative of low turnover associated with treatment. However, the amount of microdamage and the mechanical properties were similar among the control and treatment groups. As the tissue mineral density (TMD increased significantly with alendronate treatment compared to non-treated osteoporotic controls, the reduction in resorption cavities could counterbalance the higher TMD allowing the alendronate-treated bone to maintain its mechanical properties and resist microdamage accumulation. A multivariate analysis of the possible predictors supports the theory that multiple factors (e.g., body mass index, TMD, and ES/BS can impact the mechanical properties. Our results suggest that long-term alendronate treatment shows no adverse impact on mechanical cancellous bone characteristics.

GRDF tablets were characterized with the effects of different molecular weights (MWs of chitosan (CS and hydroxyethyl cellulose (HEC at various ratios on swelling, floating, and physical integrity. The CS component was formed using various acids: acetic, lactic, malic, succinic, and citric, and a high viscosity grade of HEC was selected. The results demonstrated that the swelling ratios of the formulations comprising high MW CS were lower than those of low or medium MW CS when salts were formed with any countering acids except for acetic acid. The decreasing ranking of the swelling rates was: CS-citrate > CS-malate > CS-lactate > CS-succinate > CS-acetate. A negative correlation was found between the pKa of the respective countering acid and the swelling rate. The swelling rate was promoted if an acidic salt of CS with a lower water content was incorporated, while it became slower when tablet hardness was higher or the compression force to form tablets was increased. Although HEC did not contribute to swelling or floating, it played a role in maintaining structural integrity. A prolonged dissolution profile of alendronate GRDF tablets developed in this study was observed.Keywords: gastroretentive dosage form, chitosan, hydrogel, hydroxyethyl cellulose, swelling, alendronate

  17. Pullulan: an advantageous natural polysaccharide excipient to formulate tablets of alendronate-loaded microparticles

    2015-03-01

    Full Text Available This work reports the preparation of tablets by direct compression of sodium alendronate-loaded microparticles, using pullulan as filler. The tableting properties of pullulan were compared with those of microcrystalline cellulose and lactose. Pullulan tablets showed low variations in average weight, thickness and drug content. Moreover, these tablets exhibited a higher hardness compared to the other excipients. In vitro release studies showed that only pullulan was capable to maintain gastroresistance and release properties of microparticles, due to its ability to protect particles against damage caused by compression force. Thus, pullulan was considered an advantageous excipient to prepare tableted microparticles.

    At present there is no oral medicine available which is effective for advanced or recurrent case of elderly patients with gynecologic cancer. We report that a low-dose biweekly paclitaxel administration preserves quality of life (QOL) and seems to be "tumor dormancy like" therapy of good compliance with few side effects. A total of 11 cases were in ovarian cancer (5), uterine cancer (3), cervical cancer (2), and uterine sarcoma (1). The median age was 68 years old and the age range was 50 to 79 years old. We performed a standard treatment as a first time treatment. Afterwards, we obtained complete informed consent from the patients for progressive or recurrent cancer and administered biweekly paclitaxel 70 mg/m2 (80-100 mg/body) on an outpatient basis. We reviewed the effect, side effect and compliance of the medication. We judged the side effect based on the Japanese cancer treatment society common toxicity criteria. The result was only one patient death from PD and the other 10 patients were PR or a state of NC without side effect. An ovary cancer case patient lived for 67 months at best, an endometrial cancer case patient lived for 62 months at best, a cervical cancer case patient lived for 74 months at best, and a recurrent uterine sarcoma case patient lived for 76 months after recurrence and the QOL was good. In addition, there was no onset of side effect more than grade 2 in all of the cases and a compliance of medical administration was good. In these cases, we thought that a low-dose of biweekly paclitaxel administration was regarded as a therapy to preserve QOL without a serious side effect and a good compliance of medication. Furthermore, we intend to increase more cases and would like to report them in the future. PMID:15918575

  19. Alendronate augments interleukin-1β release from macrophages infected with periodontal pathogenic bacteria through activation of caspase-1

    International Nuclear Information System (INIS)

    Nitrogen-containing bisphosphonates (NBPs) are anti-bone-resorptive drugs with inflammatory side effects that include osteomyelitis and osteonecrosis of the jaw. Oral bacteria have been considered to be a trigger for these NBP-associated jaw bone diseases. The present study examined the effects of alendronate (a typical NBP) and clodronate (a non-NBP) on the production of proinflammatory cytokines by macrophages infected with Porphyromonas gingivalis and Tannerella forsythia, which are important pathogens of periodontal diseases. Pretreatment with alendronate augmented IL-1β, but not TNFα, production by macrophages infected with P. gingivalis or T. forsythia. This augmentation of IL-1β production was inhibited by clodronate. Furthermore, caspase-1, a promoter of IL-1β production, was activated by treatment with alendronate, and caspase-1 inhibitor reduced the production of IL-1β induced by alendronate and P. gingivalis. These results suggest that NBPs augment periodontal pathogenic bacteria-induced IL-1β release via caspase-1 activation, and this phenomenon may contribute to the development of NBP-associated inflammatory side effects including jaw osteomyelitis. Co-treatment with clodronate may prevent and/or reduce these inflammatory effects induced by NBPs

    2011-09-01

    Mesoporous silica is a promising drug delivery vehicle due to its large surface area and order porous structure. Hydroxyapatite-modified mesoporous silica materials (MSH) have been developed, and the cytotoxicity of MSH and unmodified mesoporous silica (HMS) has also been studied in this work. The results indicated that MSH exhibited lower cytotoxicity than HMS. The drug release property of MSH was also investigated in this paper. Alendronate (AL) was laden into MSH and HMS, respectively. MSH exhibited long release period lasting over 30 days with a weak burst release in the first 5 days; however, the AL release period of HMS was just 5 days with a remarkable burst release. In addition, the osteogenic commitment induced in human marrow mesenchymal stem cells (MSCs) by MSH-alendronate (MSH-AL) was also investigated, and the osteogenesis of MSCs was evaluated by alkaline phosphatase (ALP) assay. The osteogenesis of MSCs induced by MSH-AL is comparable to that induced by the osteogenic medium. Taken together, MSH can be severed as potential bone repair materials with lower cytotoxicity.

    Full Text Available Venous insufficiency is a common, chronic disease that affects nearly half of the population in highly developed countries. The vast majority of affected patients suffer from varicose veins (VV. Recently, the priority in medicine has been patient satisfaction with treatment and high quality of life. Therefore, disease-specific questionnaires that measure quality of life have been developed. One of these is VEINES-QOL/Sym with two subscales that assess quality of life and disease symptoms. To date, it has been used to examine patients with venous ulcers and thrombosis. No data are available concerning the use of VEINES to assess patients after VV surgery.

    The objective of the present study was to evaluate the effect of 17beta-estradiol or alendronate in preventing bone loss in 3-month-old ovariectomized Wistar rats. One group underwent sham ovariectomy (control, N = 10), and the remaining three underwent double ovariectomy. One ovariectomized group did not receive any treatment (OVX, N = 12). A second received subcutaneous 17beta-estradiol at a dose of 30 microg/kg for 6 weeks (OVX-E, N = 11) and a third, subcutaneous alendronate at a dose of 0.1 mg/kg for 6 weeks (OVX-A, N = 8). Histomorphometry, densitometry, osteocalcin and deoxypyridinoline measurements were applied to all groups. After 6 weeks there was a significant decrease in bone mineral density (BMD) at the trabecular site (distal femur) in OVX rats. Both alendronate and 17beta-estradiol increased the BMD of ovariectomized rats, with the BMD of the OVX-A group being higher than that of the OVX-E group. Histomorphometry of the distal femur showed a decrease in trabecular volume in the untreated group (OVX), and an increase in the two treated groups, principally in the alendronate group. In OVX-A there was a greater increase in trabecular number. An increase in trabecular thickness, however, was seen only in the OVX-E group. There was also a decrease in bone turnover in both OVX-E and OVX-A. The osteocalcin and deoxypyridinoline levels were decreased in both treated groups, mainly in OVX-A. Although both drugs were effective in inhibiting bone loss, alendronate proved to be more effective than estradiol at the doses used in increasing bone mass. PMID:11471040

    The aim of the present study was to investigate the local effect of 10% doxycycline and 1% alendronate combined with poly(lactic-co-glycolic acid) (PLGA) on bone repair. Thirty rats were divided into three groups, as follows: control group (CG), drug group (DG), and vehicle-PLGA group (VG). Bone defect was created in the right femur and filled with the following: blood clot (CG); PLGA gel, 10% doxycycline and 1% alendronate (DG); or vehicle-PLGA (VG). The animals were euthanized 7 or 15 days after surgery. Bone density, bone matrix and number of osteoclasts were quantified. At 7 days, the findings showed increased density in DG (177.75 ± 76.5) compared with CG (80.37 ± 27.4), but no difference compared with VG (147.1 ± 41.5); no statistical difference in bone neoformation CG (25.6 ± 4.8), VG (27.8 ± 4), and DG (18.9 ± 7.8); and decrease osteoclasts in DG (4.6 ± 1.9) compared with CG (26.7 ± 7.4) and VG (17.3 ± 2.7). At 15 days, DG (405.1 ± 63.1) presented higher density than CG (213.2 ± 60.9) and VG (283.4 ± 85.8); there was a significant increase in percentage of bone neoformation in DG (31.5 ± 4.2) compared with CG (23 ± 4), but no difference compared with VG (25.1 ± 2.9). There was a decreased number of osteoclasts in DG (20.7 ± 4.7) and VG (29.5 ± 5.4) compared with CG (40 ± 9.4). The results suggest that the association of 10% doxycycline and 1% alendronate with PLGA-accelerated bone repair. PMID:26381914

    Bisphosphonates (BPs) have been shown to influence angiogenesis. This may contribute to BP-associated side-effects such as osteonecrosis of the jaw (ONJ) or atypical femoral fractures (AFF). The effect of BPs on the production of angiogenic factors by osteoblasts is unclear. The aims were to investigate the effect of (1) alendronate on circulating angiogenic factors; vascular endothelial growth factor (VEGF) and angiopoietin-1 (ANG-1) in vivo and (2) zoledronate and alendronate on the production of VEGF and ANG-1 by osteoblasts in vitro. We studied 18 post-menopausal women with T score⩽-2 randomized to calcium/vitamin D only (control arm, n=8) or calcium/vitamin D and alendronate 70mg weekly (treatment arm, n=10). Circulating concentrations of VEGF and ANG-1 were measured at baseline, 3, 6 and 12months. Two human osteoblastic cell lines (MG-63 and HCC1) and a murine osteocytic cell line (MLO-Y4) were treated with zoledronate or alendronate at concentrations of 10(-12)-10(-6)M. VEGF and ANG-1 were measured in the cell culture supernatant. We observed a trend towards a decline in VEGF and ANG-1 at 6 and 12months following treatment with alendronate (p=0.08). Production of VEGF and ANG-1 by the MG-63 and HCC1 cells decreased significantly by 34-39% (p<0.01) following treatment with zoledronate (10(-9)-10(-6)M). Treatment of the MG-63 cells with alendronate (10(-7) and 10(-6)) led to a smaller decrease (25-28%) in VEGF (p<0.05). Zoledronate (10(-10)-10(-)(6)M) suppressed the production of ANG-1 by MG-63 cells with a decrease of 43-49% (p<0.01). Co-treatment with calcitriol (10(-8)M) partially reversed this zoledronate-induced inhibition. BPs suppress osteoblastic production of angiogenic factors. This may explain, in part, the pathogenesis of the BP-associated side-effects. PMID:25461393

  9. Brachytherapy of stage II mobile tongue carcinoma. Prediction of local control and QOL

    International Nuclear Information System (INIS)

    There is no consensus as to the prognostic model for brachytherapy of tongue carcinoma. This study was designed to evaluate the prognostic factors for local control based on a large population under a unified treatment policy. Between 1970 and 1998, 433 patients with stage II tongue squamous cell carcinoma were treated by low-dose-rate brachytherapy. This series included 277 patients treated with a linear source with a minimum follow-up of 3 years. A spacer was introduced in 1987. The primary local control rates were 85.6%. In the multivariate analysis, an invasive growth pattern was a significant factor for local recurrence. The disease-related survival was influenced by old age and an invasive growth pattern. A spacer lowered mandibular bone complications. The growth pattern was the most important factor for recurrence. Brachytherapy was associated with a high cure rate and the use of spacers brought about good quality of life (QOL)

    We conducted a microstudy to elicit health state descriptions and utility values, using the EuroQol instrument, from a sample of acutely ill inpatients on 5 wards at University College London Medical School. Most current work to date has elicited such descriptive and valuation data from random surveys of the general population. One problem with this is that most responders from the general population have not actually experienced the states being valued. Our goal was to ascertain whether there were any differences between the values given by inpatients and those of the general population. However, the small sample size of patients included in our feasibility study means our conclusions must remain tentative. Nevertheless, the results suggest that patients give higher values than the general population. We suggest that more research needs to be done eliciting values from patients. PMID:10155609

Forty-seven postmenopausal women with osteoporosis (mean age at baseline 65.7 years treated with ALN for over seven years in our outpatient clinic were analyzed. Lumbar spine bone mineral density (BMD was measured using dual energy X-ray absorptiometry, and urinary levels of cross-linked N-terminal telopeptides of type I collagen (NTX and serum alkaline phosphatase (ALP were monitored during the seven-year treatment period. Urinary NTX and serum ALP levels decreased (-48.2% at three months and -15.7% at seven years, respectively and lumbar spine BMD increased (+12.8% at seven years compared with baseline values. No serious adverse events were observed, including osteonecrosis of jaw, atypical femoral diaphysis fractures, or atrial fibrillation. To our knowledge, this is the first report of the outcome of ALN treatment for seven years in Japanese patients with osteoporosis. ALN successfully suppressed bone turnover and increased lumbar spine BMD from the baseline value over the course of the seven-year treatment period without causing any severe adverse events.Keywords: alendronate, osteoporosis, long-term treatment, bone mineral density, bone turnover

    Full Text Available OBJECTIVE: To test psychometrics of the Short Form 36 Health Survey version 2 (SF-36v2 and the Quality of Life Scale for Drug Addicts (QOL-DAv2.0 in Chinese mainland patients with methadone maintenance treatment (MMT. METHODS: A total of 1,212 patients were recruited from two MMT clinics in Xi'an, China. Reliability was estimated with Cronbach's α and intra-class correlation (ICC. Convergent and discriminant validity was assessed using multitrait-multimethod correlation matrix. Sensitivity was measured with ANOVA and relative efficiency. Responsiveness was evaluated by pre-post paired-samples t-test and standardized response mean based on the patients' health status changes following 6-month period. RESULTS: Cronbach's α of the SF-36v2 physical and mental summary components were 0.80 and 0.86 (eight scales range 0.73-0.92 and the QOL-DAv2.0 was 0.96 (four scales range: 0.80-0.93. ICC of the SF-36v2 two components were 0.86 and 0.85 (eight scales range: 0.72-0.87 and the QOL-DAv2.0 was 0.94 (four scales range: 0.88-0.92. Convergent validity was lower between the two instruments (γ <0.70 while discriminant validity was acceptable within each instrument. Sensitivity was satisfied in self-evaluated health status (both instruments and average daily methadone dose (SF-36v2 physical functioning and vitality scales; QOL-DAv2.0 except psychology scale. Responsiveness was acceptable in the improved health status change (SF-36v2 except vitality scale; QOL-DAv2.0 except psychology and symptoms scales and deteriorated health status change (SF-36v2 except vitality, social functioning and mental health scales; QOL-DAv2.0 except society scale. CONCLUSIONS: The SF-36v2 and the QOL-DAv2.0 are valid tools and can be used independently or complementary according to different emphases of health-related quality of life evaluation in patients with MMT.

    Full Text Available Abstract Aims To compare quality of life (QOL for patients with irritable bowel syndrome (IBS between the U.S. and Japan, it is indispensable to develop common instruments. The IBS-QOL, which is widely used in Western countries, was translated into Japanese as there has been a lack of Japanese disease-specific QOL measures for IBS. Methods The original 34 items of the IBS-QOL were translated from English into Japanese through two independent forward translations, resolution, back translation, and resolution of differences. Forty nine patients who had GI symptoms but did not have any organic diseases (including 30 IBS patients diagnosed by Rome II criteria were recruited from Tohoku University Hospital in Sendai, Japan and completed a Japanese version of the IBS-QOL (IBS-QOL-J concomitant with a Japanese version of the IBS severity index (IBSSI-J twice within 7–14 days. Results The IBS-QOL-J demonstrated high internal consistency (Cronbach's alpha; 0.96 and high reproducibility (intraclass correlation coefficient; 0.92, p Conclusion The IBS-QOL-J is a reliable instrument to assess the disease-specific QOL for IBS. Considering cross-cultural comparison, this measure is likely to be a valuable tool to investigate the QOL in Japanese patients with IBS.

    Information exchange is popular among local Laotian women where the infrastructure is insufficient and health interventions often use existing local networks or information exchanges. In this study, we explored the relationship between quality of life (QOL) among Laotian women and their active or passive relationship with their neighborhood. A total of 666 households were randomly selected in four villages in Vientiane Capital. The housewife or equivalent in each household was asked for both face-to-face interview and self-administered questionnaire regarding her health condition and communication over the past four weeks. A Lao translation of the brief version of the World Health Organization QOL questionnaire (WHOQOL-BREF) was used to measure the subjects' health-related QOL scores. The participants were divided into active and passive communication groups based on their information exchange style. The WHOQOL- BREF scores were compared between the two groups. The active communication group had significantly higher QOL scores compared with the passive communication group (3.44 ± 0.36 vs 3.35 ± 0.36; mean ± standard deviation, p=0.003). The statistical significance remained unchanged (p=0.037) even after adjusting for age, education, occupation, and illness. In a multiple regression analysis, the standardized regression coefficient for communication style was the third largest (0.081), following education (0.189) and occupation (0.086). In conclusion, QOL related to individual health was associated with active communication among women. Besides the effects of education and occupation, QOL can be affected by active communication. Further study regarding the association between social capital and network analysis is needed. PMID:25507615

    Bisphosphonates (BPs) inhibit osteocyte and osteoblast apoptosis via opening of connexin (Cx) 43 hemichannels and activating the extracellular signal regulated kinases ERKs. Previously, we hypothesized that intracellular survival signaling is initiated by interaction of BPs with Cx43. However, using whole cell binding assays with [3H]-alendronate, herein we demonstrated the presence of saturable, specific and high affinity binding sites in the Cx43-expressing ROS 17/2.8 osteoblastic cells, au...

    Phosphonates have emerged as an alternative for functionalization of titanium surfaces by the formation of homogeneous self-assembled monolayers (SAMs) via Ti-O-P linkages. This study presents results from an investigation of the modification of Ti6Al4V alloy by chemisorption of osseoinductive alendronate using a simple, effective and clean methodology. The modified surfaces showed a tailored topography and surface chemistry as determined by SEM microscopy and RAMAN spectroscopy. X-ray photoelectron spectroscopy revealed that an effective mode of bonding is created between the metal oxide surface and the phosphate residue of alendronate, leading to formation of homogenous drug distribution along the surface. In-vitro studies showed that alendronate SAMs induce differentiation of hMSC to a bone cell phenotype and promote bone formation on modified surfaces. Here we show that this novel method for the preparation of functional coatings on titanium-based medical devices provides osseoinductive bioactive molecules to promote enhanced integration at the site of implantation.

    Full Text Available Abstract Background There is no consensus as to the prognostic model for brachytherapy of tongue carcinoma. This study was designed to evaluate the prognostic factors for local control based on a large population under a unified treatment policy. Results Between 1970 and 1998, 433 patients with stage II tongue squamous cell carcinoma were treated by low-dose-rate brachytherapy. This series included 277 patients treated with a linear source with a minimum follow-up of 3 years. A spacer was introduced in 1987. The primary local control rates were 85.6%. Conclusion In the multivariate analysis, an invasive growth pattern was a significant factor for local recurrence. The disease-related survival was influenced by old age and an invasive growth pattern. A spacer lowered mandibular bone complications. The growth pattern was the most important factor for recurrence. Brachytherapy was associated with a high cure rate and the use of spacers brought about good quality of life (QOL.

  3. Development of a head and neck companion module for the quality of life-radiation therapy instrument (QOL-RTI)

    International Nuclear Information System (INIS)

    Purpose/Objective: A review of available head and neck quality of life (QOL) instruments reveals them to inadequately address important radiation related side effects, or to be too cumbersome for routine use. The purpose of this study was to develop a head and neck disease specific module as a companion to the previously developed quality of life - radiation therapy instrument (QOL-RTI). The goal was to create a more complete, yet concise, head and neck site-specific module geared toward patients receiving radiation therapy for head and neck cancer. Methods and Materials: This exploratory study included 34 consecutive patients undergoing definitive radiotherapy over a 6-7 week course (60-79.8 Gy). We developed and administered a 14-item questionnaire to all eligible patients treated with radiotherapy for head and neck cancer who were not already registered in another research study assessing quality of life (e.g., RTOG). During the treatment period, the QOL-RTI general tool and the head and neck (H and N) module were administered as follows: at baseline, at week four (for test-retest), and at the end of the treatment period. For validation purposes the QOL-RTI/H and N was compared to the functional assessment cancer tool head and neck (FACT-H and N) questionnaire. The FACT-H and N was administered one time at week 4, on the same day as the QOL-RTI/H and N. This report includes the treatment phase of the study (during the course of radiation). Results: Mean age was 62 years (range 40-75). Internal consistency of the module was satisfactory (Chronbach's α = 0.85). Test-retest yielded a correlation coefficient of 0.90 (p < 0.001). Concurrent validity, established by comparing the module to the FACT/H and N , yielded a correlation coefficient of 0.85. Significant changes in quality of life scores during a course of radiation was noted for both general quality of life tool and the site specific module. For the head and neck module, the difference in the mean baseline

    Full Text Available The effects of alendronate (ALN treatment on the bone mineral density (BMD, bone turnover markers, and fracture incidence remain to be established in older Japanese patients. The aim of the present study was to compare the outcome of ALN treatment for 3 years among postmenopausal osteoporotic Japanese women <80 years of age and those ≥80 years of age. One hundred ninety-eight postmenopausal osteoporotic women who had been treated with ALN for more than 3 years were analyzed. The 3-year outcome was compared between women <80 years of age (control group, n=167 and those ≥80 years of age (older group, n=31. During the 3-year treatment period, the urinary cross-linked N-terminal telopeptides of the type I collagen and serum alkaline phosphatase levels significantly decreased and the lumbar spine BMD significantly increased, compared with the baseline values, in manners that were similar in the control and older groups. However, the incidence of non-vertebral fractures, but not of vertebral fractures, was significantly higher in the older group than in the control group (16.1% vs 3.0%. These results suggested that the incidence of non-vertebral fractures was significantly higher among postmenopausal osteoporotic Japanese women ≥80 years of age who were treated with ALN than among those <80 years of age despite the similar effect of ALN treatment on surrogate markers.

  5. A novel PHBV/HA microsphere releasing system loaded with alendronate

    International Nuclear Information System (INIS)

    Microspheres of poly(β-hydroxybutyrate-co-β-hydroxyvalerate) (PHBV) incorporated with hydroxyapatite (HA) and loaded with alendronate (AL), an osteoporosis preventing drugs, were prepared by single emulsion technique. Several methods were used to evaluate this novel drug carrier microsphere system (referred as PHBV/HA-AL). Fourier transform infrared (FTIR) was used to evaluate the enwrapping of HA and the X-ray diffraction (XRD) analysis further confirmed the success. The morphology of PHBV/HA-AL microspheres was observed by scanning electron microscope (SEM), showing rough surface with HA particles enwrapped in the PHBV matrix. The in vitro drug releasing profile of PHBV/HA-AL system was investigated in a 26-day period. There is a sustained releasing pattern after a slight burst release during the first few days. Additionally, rabbit mesenchymal stem cells (MSCs) were used to evaluate the cytotoxicity of the PHBV/HA-AL composites. This controlled release system can well support the proliferation of MSCs. The novel PHBV/HA-AL controlled release system is promising for bone repair therapy.

    2005-07-01

    Full Text Available Abstract Background Alendronate has been found to reduce the risk of fractures in postmenopausal women as demonstrated in multiple randomized controlled trials enrolling thousands of women. Yet there is a paucity of such randomized controlled trials in osteoporotic men. Our objective was to systematically review the anti-fracture efficacy of alendronate in men with low bone mass or with a history of prevalent fracture(s and incorporate prior knowledge of alendronate efficacy in women in the analysis. Methods We examined randomized controlled trials in men comparing the anti-fracture efficacy of alendronate to placebo or calcium or vitamin D, or any combination of these. Studies of men with secondary causes of osteoporosis other than hypogonadism were excluded. We searched the following electronic databases (without language restrictions for potentially relevant citations: Medline, Medline in Process (1966-May 24/2004, and Embase (1996–2004. We also contacted the manufacturer of the drug in search of other relevant trials. Two reviewers independently identified two trials (including 375 men, which met all inclusion criteria. Data were abstracted by one reviewer and checked by another. Results of the male trials were pooled using Bayesian random effects models, incorporating prior information of anti-fracture efficacy from meta-analyses of women. Results The odds ratios of incident fractures in men (with 95% credibility intervals with alendronate (10 mg daily were: vertebral fractures, 0.44 (0.23, 0.83 and non-vertebral fractures, 0.60 (0.29, 1.44. Conclusion In conclusion, alendronate decreases the risk of vertebral fractures in men at risk. There is currently insufficient evidence of a statistically significant reduction of non-vertebral fractures, but the paucity of trials in men limit the statistical power to detect such an effect.

    In this study, production, quality control and biodistribution studies of {sup 166}Ho-alendronate have been presented and followed by dosimetric evaluation for human based on biodistribution data in wild-type rats. {sup 166}Ho chloride was obtained by thermal neutron irradiation of natural {sup 165}Ho(NO{sub 3}){sub 3} samples. {sup 166}Ho-alendronate complex was prepared by adding the desired amount of alkaline alendronate solution (0.2 mL, 150 mg/mL) to 3-5 mCi of the {sup 166}HoCl{sub 3} solution. Radiochemical purity of the complex was monitored by instant thin layer chromatography (ITLC). {sup 166}Ho-alendronate complex was prepared in high radiochemical purity (> 99%, ITLC) and specific activity of 4.4 GBq/mmol. Stability studies of the complex in the final preparation and in the presence of human serum were performed up to 48 h. The major accumulation of the radio-complex was in the bone tissues followed by absorbed dose evaluation of each human organ by RADAR software used for modelling the radiation dose delivered. The final preparation was administered to wild-type rats and biodistribution of the complex was performed 2-48 h post injection showing major accumulation of the complex in the bone tissue. The highest absorbed dose for {sup 166}Ho-alendronate is observed in bone surface and red marrow with 2.670 and 1.880 mSv/MBq; respectively. These findings suggest that {sup 166}Ho-alendronate has considerable characteristics compared to {sup 166}Ho-DOTMP and can be a possible candidate for bone marrow ablation in patients with multiple myeloma.

  9. Hearing preservation after radiotherapy for vestibular schwannomas is comparable to hearing deterioration in healthy adults and is accompanied by local tumor control and a highly preserved quality of life (QOL) as patients’ self-reported outcome

    International Nuclear Information System (INIS)

    Purpose: To evaluate long-term results and patients’ self-reported outcome of high-precision photon radiotherapy for the treatment of patients with vestibular schwannoma (VS). Methods and materials: We treated 246 patients with 248 VS with fractionated stereotactic radiotherapy (FSRT) or stereotactic radiosurgery (SRS). For FSRT, a median total dose of 57.6 Gy was prescribed in median single doses of 1.8 Gy, for SRS, a median dose of 13 Gy/80% isodose was applied. Of all patients, 51 patients died during follow-up. To evaluate long-term toxicity and QOL, we sent out a questionnaire to all living patients; of these, 81 patients (42%) sent back the questionnaire. Results: Median local control was 84 months, actuarial local control rates for both groups (SRS and FSRT) were 98% after 2, 95% after 5, and 93% after 10 years; there was no statistical difference between FSRT and SRS. Hearing deterioration was significantly higher in the SRS group than the FSRT group. However, when comparing FSRT to SRS with doses ⩽ 13 Gy, hearing preservation is comparable. In patients with useful hearing, hearing preservation was 89.7% at 1 year, 84.7% at 3 years, 76.5% at 5 years, and 68.6% at 10 years. After 10 years of follow-up, hearing deterioration can be observed in both subgroups. In the FSRT group, facial nerve toxicity rate was 1.6%. Trigeminal nerve toxicity was observed in 2.1% after FSRT. Overall QOL was unchanged in 47% of the patients after RT, and 31% reported an improvement in QOL during follow-up. Conclusion: Patients’ self-reported outcome confirms good results with respect to tumor control and QOL after FSRT or SRS in patients with VS. SRS can be associated with higher side effect following a dose-dependency. In long-term follow-up, hearing deterioration is most likely attributed to normal aging, but not treatment-related

    Full Text Available Abstract Background In order to adapt oral care and treatment to the demands of the growing group of frail dentulous older people, it is important to understand how and to which extent having natural teeth contributes to the quality of life (QoL of frail older people and how frailty influences their perspective. Methods A qualitative approach was used. Interviews with 38 Dutch frail older dentulous people were tape-recorded, transcribed, coded for content and analyzed. Additional information was collected which included age, gender, living situation, use of dental prostheses, self-reported oral health status, chronic disorders, and an index for frailty. Results Seven themes were identified in the relationship between natural teeth and the QoL of the participants: pride and achievement; intactness; sense of control; oral function; appearance; comfort; along with coping and adapting to disabilities. Having natural teeth generally had a positive effect on QoL. Positive effects through pride and achievement, intactness, and sense of control were most apparent for the most severely frail. They compared themselves with peers who are more often edentate, and valued the good state of their teeth against the background of their declining health, especially those with disabilities causing severe chronic pain or impaired fine-motor skills. The effect of coping with and adaptation to tooth loss was also most apparent for the most severely frail. There was a gender effect in that the men generally cared less about having natural teeth than women, regardless of their level of frailty. Conclusions QoL of frail older people is positively influenced by natural teeth, and this effect seems to increase with increasing frailty. Preservation of teeth contributes to a positive body image and self-worth. Oral care for frail people should aim to preserve natural teeth if possible.

These methodologies employed reversed-phase or ion-exchange HPLC analysis, both associated with different detectors: UV and fluorescence detection after derivatization of the drug, conductivity and refractive index detectors, as well as the indirect UV detection. Titrimetry and spectrophotometry (with previous complexation of the drug, which are simpler procedures, were also described, but they showed poor specificity when compared to liquid chromatography.

    Aim: To investigate the long-term effects of alendronate (Aln), a widely used oral bisphosphonate, on fracture healing and bone remodeling in ovariectomized rats. Methods: Adult female SD rats underwent ovariectomy, and then bilateral femoral osteotomy at 12 weeks post-ovariectomy. From d 2 post-ovariectomy, the animals were divided into 3 groups, and treated with Aln (3 mg·kg−1·d−1, po) for 28 weeks (Aln/Aln), Aln for 12 weeks and saline for 16 weeks (Aln/Saline) or saline for 28 weeks (Sali...

  18. Mutual augmentation of the induction of the histamine-forming enzyme, histidine decarboxylase, between alendronate and immuno-stimulants (IL-1, TNF, and LPS), and its prevention by clodronate

    International Nuclear Information System (INIS)

    Nitrogen-containing bisphosphonates (N-BPs), powerful anti-bone-resorptive drugs, have inflammatory side effects, while histamine is not only an inflammatory mediator, but also an immuno-modifier. In murine models, a single intraperitoneal injection of an N-BP induces various inflammatory reactions, including the induction of the histamine-forming enzyme histidine decarboxylase (HDC) in tissues important in immune responses (such as liver, lungs, spleen, and bone marrow). Lipopolysaccharide (LPS) and the proinflammatory cytokines IL-1 and TNF are also capable of inducing HDC. We reported previously that in mice (i) the inflammatory actions of N-BPs depend on IL-1 (ii) N-BP pretreatment augments both LPS-stimulated IL-1 production and HDC induction, and (iii) the co-administration of clodronate (a non-N-BP) with an N-BP inhibits the latter's inflammatory actions (including HDC induction). Here, we add the new findings that (a) pretreatment with alendronate (a typical N-BP) augments both IL-1- and TNF-induced HDC elevations, (b) LPS pretreatment augments the alendronate-induced HDC elevation, (c) co-administration of clodronate with alendronate abolishes these augmentations, (d) alendronate does not induce HDC in IL-1-deficient mice even if they are pretreated with LPS, and (e) alendronate increases IL-1β in all tissues tested, but not in the serum. These results suggest that (1) there are mutual augmentations between alendronate and immuno-stimulants (IL-1, TNF, and LPS) in HDC induction, (2) tissue IL-1β is important in alendronate-stimulated HDC induction, and (3) combination use of clodronate may have the potential to reduce the inflammatory effects of alendronate (we previously found that clodronate, conveniently, does not inhibit the anti-bone-resorptive activity of alendronate)

    This study assessed quality of life (QoL), depression, and anxiety before and after orthognathic surgery and identified risk factors for poorer postoperative outcome. This multicentre prospective study included 140 patients from five French medical centres. We assessed patients before surgery (T1), 3 months after surgery (T2), and 12 months after surgery (T3). We assessed the severity of the orofacial deformity, physical, psychological, social, and environmental QoL (WHOQOL-BREF), and depression and anxiety (GHQ-28). Risk factors for poorer outcome were identified using linear mixed models. Between baseline and 12 months, there was significant improvement in psychological and social QoL and in depression (although below the norms reported in the general population), but not in anxiety. Physical QoL was poorer in patients who were younger, who had a mild orofacial deformity, and who were depressed. Psychological QoL was poorer in younger patients and in depressed patients. Social QoL was poorer in patients who were single, who had a mild orofacial deformity, and who were depressed. Although orthognathic surgery provides a moderate improvement in psychological and social QoL, the systematic screening and treatment of depression could further improve QoL after surgery because it is a major predictor of poor QoL in this population.

  20. Characterization of alendronate sodium-loaded UHMWPE for anti-osteolysis in orthopedic applications

    International Nuclear Information System (INIS)

    Ultra-high molecule weight polyethylene (UHMWPE) loaded with alendronate sodium (ALN), a potential drug to prevent debris-induced osteolysis, was developed in our previous study. This study aims to investigate the wear performance of UHMWPE–ALNs. In this study, wear test, mechanical test, differential scanning calorimetry (DSC) and contact angle test were applied to characterize the wear performance, mechanical behavior and physical properties of UHMWPE–ALNs. The effect of ALN on the wear performance of UHMWPE–ALNs was investigated by scanning electron microscope (SEM), back scattering electrons (BSE) and energy dispersive X-ray spectrum (EDX). The results of wear test showed that the friction coefficient and volumetric loss of UHMWPE–ALN 0.5 wt.% were comparable with those of UHMWPE. The result of SEM-BSE-EDX revealed that the wear debris detached easily from the ALN-agglomerated regions, which was mainly responsible for the decrease of wear resistance of UHMWPE–ALN 1.0 wt.%. The loaded ALN resulted in the increase of hydrophilicity of UHMWPE–ALNs. The decrease of toughness and crystallinity of UHMWPE–ALN 1.0 wt.% attributed to the non-uniform distribution of ALN. The UHMWPE–ALN 0.5 wt.%, in which no ALN agglomeration was observed, possessed approving mechanical properties and wear performance, might have potential clinical application to prevent the debris-induced osteolysis in prosthetic joints. - Highlights: ► The wear resistance, mechanical and physical properties UHMWPE–ALN 0.5 wt.% are not significantly different with those of UHMWPE. ► The hydrophilicity of UHMWPE increased after loaded ALN. ► The decrease of wear performance of UHMWPE–ALN 1.0 wt.% attributed to the non uniform distribution of ALN. ► The ALN-agglomerated region of UHMWPE–ALN 1.0 wt.% was most easily worn out during wear processing.

    Osteoporosis (OP) is a major health problem characterized by compromised bone strength. Osteoarthritis (OA) is a joint disease that progresses slowly and is characterized by breakdown of the cartilage matrix. Alendronate (ALN), a nitrogen-containing bisphosphonate (BIS), inhibits bone loss and increases bone mineralization, and has been used clinically for the treatment of OP. It is still controversial whether BIS is effective in inhibiting the progression of OA. Chondrocyte apoptosis has been described in both human and experimentally induced OA models. In our study we aimed to detect whether ALN could protect articular cartilage from degeneration and reduce apoptosis rates in experimentally OA induced rats. For this rats were ovariectomized (ovex), nine weeks after operation rats were injected 30 µg/kg/week ALN subcutaneously for six weeks. After six weeks articular cartilages were obtained. We did Safranin O staining and Mankin and Pritzker scorings to evaluate degeneration and investigated the expressions of p53, cleaved caspase 3, Poly ADP-ribose (PAR), Poly ADP-ribose polymerase 1 (PARP 1), and applied TUNEL technique to determine apoptotis rates. We found a significant decrease in glycosaminoglycan (GAG) amount and increased apoptosis which indicates damage on articular cartilages of ovex rats. GAG amount was higher and apoptosis rate was lower on articular cartilages of ALN treated ovex rats compared to the ovex group. In contrary to studies showing that early ALN treatment has a protective effect, our study shows late ALN treatment has a chondroprotective effect on articular cartilage since we treated rats nine weeks after ovariectomy.

  3. In vitro incorporation studies of 99mTc-alendronate sodium at different bone cell lines

    International Nuclear Information System (INIS)

    Bisphosphonates can be labeled with Technetium-99m (99mTc) and are used for bone imaging because of their good localization in the skeleton and rapid clearance from soft tissues. Over the last decades bone scintigraphy has been used extensively in the evaluation of oncological patients to provide information about the sites of bone lesions, their prognosis and the effectiveness of therapy by showing the sequential changes in tracer uptake. Since the lesion visualization and lesion/bone ratio are important utilities for a bone scanning radiopharmaceutic; in this study incorporation of 99mTc labeled alendronate sodium (99mTc-ALD) was evaluated in U2OS (human bone osteosarcoma) and NCI-H209 (human bone carcinoma) cell lines. ALD was directly labeled by 99mTc, radiochemical purity and stability of the complex were analyzed by radioactive thin layer chromatography and radioactive high performance liquid chromatography studies. For cell incorporation study, NCI-H209 and U2OS cell lines were used with standard cell culture methods. The six well plates were used for all experiments and the integrity of each cell monolayer was checked by measuring its transepithelial electrical resistance (TEER) with an epithelial voltammeter. Results confirmed that ALD was successfully radiolabeled with 99mTc. 99mTc-ALD incorporated with NCI-H209 and U2OS cells. The uptake percentages of 99mTc-ALD in NCI-H209 and U2OS cell lines were found significantly different. Since 99mTc-ALD highly uptake in cancer cell line, the results demonstrated that radiolabeled ALD may be a promising agent for bone cancer diagnosis. (author)

    Hepatocellular carcinoma (HCC) is the third leading cause of cancer related deaths around the world. Due to late diagnosis and development of drug resistance in patients suffering from HCC, development of more effective therapeutic strategies is inevitable. The aim of this study was to evaluate the combined apoptotic effect of 5'-Azacytidine (5'-AzaC) and alendronate (ALN) on Huh-7 HCC cell line and to explore differential expression at genomics and proteomics level. Incubation of HCC cell line with 5'-AzaC alone showed cell death in a time and dose dependent manner while in combination with ALN, increased cytotoxicity was observed. Up-regulation of CASP7(Caspase7) and LZTS1 (leucine zipper, putative tumor suppressor 1) and down-regulation of DNMT1(DNA (cytosine-5-)-methyltransferase 1) was noted in treated cells. Proteomic studies on the treated cells revealed altered expression of different proteins including peroxiredoxin 2 (Prx2), Annexin 5 (Anx5), Rho GTPase activating protein (RhoGAP), Nuclear factor-kappa B (NF-kB), tumor necrosis factor alpha-induced protein (TNF), triosephosphate isomerase (TPI), Glutathione S transferase (GSTP1) and Heat shock protein60 (HSP60). Our study demonstrated the cytotoxic effect of 5'-AzaC and ALN drug combination on Huh-7 HCC cells suggesting such combinations may be explored as a possible therapeutic approach. Current study revealed that Huh-7 HCC cells are sensitive to 5'-AzaC and ALN drug combination and such combination approaches could lead to the development of new therapeutic strategies. Furthermore, we also report the expression of Anx5 exclusively in untreated cancerous cell line indicating the possibility of being used as a potential therapeutic target and biomarker.

    Odanacatib (ODN) is a bone resorption inhibitor which differs from standard antiresorptives by its ability to reduce bone resorption without decreasing bone formation. What is the reason for this difference? In contrast with other antiresorptives, such as alendronate (ALN), ODN targets only the very last step of the resorption process. We hypothesize that ODN may therefore modify the remodeling events immediately following osteoclastic resorption. These events belong to the reversal phase and include recruitment of osteoblasts, which is critical for connecting bone resorption to formation. We performed a histomorphometric study of trabecular remodeling in vertebrae of estrogen-deficient rabbits treated or not with ODN or ALN, a model where ODN, but not ALN, was previously shown to preserve bone formation. In line with our hypothesis, we found that ODN treatment compared to ALN results in a shorter reversal phase, faster initiation of osteoid deposition on the eroded surfaces, and higher osteoblast recruitment. The latter is reflected by higher densities of mature bone forming osteoblasts and an increased subpopulation of cuboidal osteoblasts. Furthermore, we found an increase in the interface between osteoclasts and surrounding osteoblast-lineage cells. This increase is expected to favor the osteoclast-osteoblast interactions required for bone formation. Regarding bone resorption itself, we show that ODN, but not ALN, treatment results in shallower resorption lacunae, a geometry favoring bone stiffness. We conclude that, compared to standard antiresorptives, ODN shows distinctive effects on resorption geometry and on reversal phase activities which positively affect osteoblast recruitment and may therefore favor bone formation.

    Importance A recent randomized radiation dose escalation trial in unresectable stage III NSCLC showed a lower survival in the high-dose arm (74Gy vs. 60Gy) with concurrent chemotherapy. Quality of life (QOL), an important secondary endpoint, is presented here. Objective The primary QOL hypothesis predicted a clinically meaningful decline (CMD) in QOL via the Functional Assessment of Cancer Therapy-Lung Cancer Subscale (FACT-LCS) in the high-dose RT-arm at 3 months. Design RTOG 0617 was a randomized phase III study (conducted from Nov 2007 to Nov 2011) in stage III NSCLC using a 2×2 factorial design and stratified by histology, PET staging, performance status and radiation technique (3D-conformal RT [3DCRT] vs. intensity-modulated radiation [IMRT]). Setting 185 institutions in the USA and Canada. Participants Of 424 eligible stage III NSCLC patients randomized, 360 (85%) consented to QOL, of whom 313 (88%) completed baseline QOL assessments. Intervention for Clinical Trials 74Gy vs. 60Gy with concurrent and consolidation carboplatin/paclitaxel +/− cetuximab. Main Outcomes and Measures QOL was collected prospectively via FACT-Trial Outcome Index (FACT-TOI), equaling Physical-Well-Being (PWB) + Functional-Well-Being (FWB) + Lung Cancer Subscale (LCS). Data are presented at baseline & 3 and 12 months via minimal clinically meaningful changes of >=2 points for PWB, FWB or LCS or >=5 points for TOI. Results Patient demographics and baseline QOL scores were comparable between the 74Gy and 60Gy arms. Two-hundred-nineteen (72%) of living patients who completed QOL at baseline did so at 3 months and 137 (57%) of living patients did so at 12 months. Significantly more patients on 74Gy arm had clinically meaningful decline in FACT-LCS at 3 months than on the 60Gy arm (45% vs. 30%, p=0.02). At 12 months, fewer patients who received IMRT (vs 3DCRT) had clinically meaningful decline in FACT-LCS (21% vs 46%, p=0.003). Baseline FACT-TOI was associated with overall survival in

    Bisphosphonates (BPs) inhibit osteocyte and osteoblast apoptosis via opening of connexin (Cx) 43 hemichannels and activating the extracellular signal regulated kinases ERKs. Previously, we hypothesized that intracellular survival signaling is initiated by interaction of BPs with Cx43. However, using whole cell binding assays with [(3)H]-alendronate, herein we demonstrated the presence of saturable, specific and high affinity binding sites in the Cx43-expressing ROS 17/2.8 osteoblastic cells, authentic osteoblasts and MLO-Y4 cells expressing Cx43 or not, as well as in HeLa cells lacking Cx43 expression and ROS 17/2.8 cells pretreated with agents that disassemble Cx channels. In addition, both BPs and the PTP inhibitor Na(3)VO(4) increased proliferation of cells expressing Cx43 or not. Furthermore, although BPs are internalized and inhibit intracellular enzymes in osteoclasts, whether the drugs penetrate non-resorptive bone cells is not known. To clarify this, we evaluated the osteoblastic uptake of AF-ALN, a fluorescently labeled analog of alendronate. AF-ALN was rapidly internalized in cells expressing Cx43 or not indicating that this process is not mediated via Cx43 hemichannels. Altogether, these findings suggest that although required for triggering intracellular survival signaling by BPs, Cx43 is dispensable for cellular BP binding, its uptake, as well as the proliferative effects of these agents.

  9. Development of a head and neck companion module for the quality of life - radiation therapy instrument (QOL-RTI)

    International Nuclear Information System (INIS)

    Purpose/Objective: The purpose of this study is to develop a Likert version, disease specific module for the Quality of Life - Radiation Therapy Instrument (QOL-RTI) for head and neck patients. This module combined with the QOL-RTI may help us to determine what changes, if any, occur in the quality of life of patients receiving primary radiation therapy for head and neck cancer. A compelling reason to study head and neck patients is because of the extensive difficulties these patients experience while undergoing radiotherapy. Their psychological and emotional well-being may also have an adverse affect on their quality of life as they strive to cope with both a life-threatening disease and with the prospect of disfigurement or dysfunction that cannot be hidden from view. Many tools have been developed to measure quality of life, however, previously published literature has focused on quantifying functional status and toxicity assessment rather than the alteration of quality of life as perceived by the patient. This study, limited to patients receiving primary radiation, is expected to yield a tool that is applicable to the patient receiving multi-modality treatment for head and neck cancer and will be useful to the physician/nurse in determining interventions for these patients. Materials and Methods: This study is an uncontrolled, non-randomized exploratory study, including fifty (50) consecutive eligible patients undergoing definitive primary radiotherapy. The questionnaires were given to all eligible patients being treated with radiotherapy for head and neck cancer who are not already registered on another research study assessing Quality of Life (i.e. RTOG). During the 5-8 week treatment period, the QOL-RTI/H and N instrument is administered as follows: at baseline evaluation (immediately prior to the beginning of radiotherapy), at week four (4) two days in a row (for test-retest) and at the end of the treatment period. For validation purposes the QOL-RTI/H and

A retrospective study was conducted to investigate the 3-year outcome of combined treatment with alendronate and alfacalcidol in patients with severe bone loss (BMD ≤ 50% of the young adult mean and osteoporotic fracture.Methods: Thirty-four patients (six men and 28 postmenopausal women with primary or secondary osteoporosis who had been treated with alendronate and alfacalcidol for more than 3 years were analyzed. The lumbar spine or total hip BMD and bone turnover markers were monitored, and the incidence of osteoporotic fractures was assessed.Results: The urinary level of cross-linked N-terminal telopeptides of type I collagen and serum level of alkaline phosphatase significantly decreased (-42.5% at 3 months and -18.9% at 3 years, and the lumbar spine BMD, but not the total hip BMD, significantly increased (14.8% at 3 years, compared with the baseline values. However, the incidence of vertebral and nonvertebral fractures was 26.5% and 2.9%, respectively, suggesting a high incidence of vertebral fractures.Conclusion: The results of the present study suggest that combined treatment with alendronate and alfacalcidol may be useful to reduce bone turnover and increase the lumbar spine BMD in patients with severe bone loss and osteoporotic fracture. However, its efficacy against vertebral fractures appears not to be sufficient. Thus, anabolic agents such as teriparatide should be taken into consideration as first-line drugs in patients with severe osteoporosis.Keywords: osteoporosis

    Current osteoporosis treatments improve bone mass by increasing net bone formation: anti-resorptive drugs such as bisphosphonates block osteoclast activity, while anabolic agents such as parathyroid hormone (PTH) increase bone remodeling, with a greater effect on formation. Although these drugs are widely used, their role in modulating formation and resorption is not fully understood, due in part to technical limitations in the ability to longitudinally assess bone remodeling. Importantly, it is not known whether or not PTH-induced bone formation is independent of resorption, resulting in controversy over the effectiveness of combination therapies that use both PTH and an anti-resorptive. In this study, we developed a μCT-based, in vivo dynamic bone histomorphometry technique for rat tibiae, and applied this method to longitudinally track changes in bone resorption and formation as a result of treatment with alendronate (ALN), PTH, or combination therapy of both PTH and ALN (PTH+ALN). Correlations between our μCT-based measures of bone formation and measures of bone formation based on calcein-labeled histology (r = 0.72 - 0.83) confirm the accuracy of this method. Bone remodeling parameters measured through μCT-based in vivo dynamic bone histomorphometry indicate an increased rate of bone formation in rats treated with PTH and PTH+ALN, together with a decrease in bone resorption measures in rats treated with ALN and PTH+ALN. These results were further supported by traditional histology-based measurements, suggesting that PTH was able to induce bone formation while bone resorption was suppressed. PMID:25554598

    Full Text Available Introduction: celiac disease is a chronic condition that requires continued treatment, with the resultant impact on health-related quality of life (HRQOL of people who suffer it. Most studies in this field have used generic questionnaires to measure HRQOL in celiac patients. It was therefore decided to conduct a study to translate into Spanish and validate a specific questionnaire for celiac disease, the Celiac Disease Quality Of Life Survey (CD-QOL. Objectives: to translate and validate in Spanish the specific celiac disease questionnaire CD-QOL. Methods: a multicenter, prospective, observational study was designed consisting of two phases: In the first phase, the questionnaire was translated and adapted into Spanish using the translation/back translation procedure and an understandability study. In the second phase, internal consistency of the translated questionnaire was analyzed. For this, results of the CD-QOL were compared to those of EuroQol and the Daily Fatigue Impact Scale (D-FIS. Understandability of the translated and adapted questionnaire was tested in six patients, and the validation study was done in 298 celiac patients (201 treated with a gluten-free diet and 97 at diagnosis. Results: in both celiac groups, Cronbach's alpha coefficient was high (0.90, feasibility was excellent (99.2 % of patients completed all questions, and there were no ceiling and floor effects. Spearman correlation to EuroQol and D-FIS was statistically significant (p < 0.05. CD-QOL score was different depending on whether state of health was good, fair, or poor based on the EuroQol score. Conclusion: the Spanish version of the CD-QOL is a valid tool for measuring HRQOL in celiac patients.

    [Purpose] This study investigated the effectiveness of a class- and home-based exercise with massage between Thai traditional and standardized physical therapy (TPT and SPT) in older people with knee osteoarthritis (KOA). [Subjects and Methods] Thirty-one subjects with KOA (aged 50-85 years) in two selected villages were randomly assigned into the TPT or SPT programs. Seventeen TPT subjects received Thai exercise with traditional massage, and 14 SPT individuals performed strengthening exercise with Swedish massage. Both programs consisted of a class with supervision plus home self-care for 8 weeks; the subjects then managed home self-care for 1 year. [Results] After 2 months, the six-minute walk test (6MWT), Western Ontario and McMaster Universities Arthritis Index (WOMAC), and SF-36 testing showed significant improvement in both groups, but the improvement of the TPT group was greater. After 1year, only the score for the 6MWT was greater in the TPT group than in the SPT group. [Conclusion] The TPT program yielded better results for the 6MWT, but, both programs had beneficial effects on the pain, function, and QOL of middle-aged and older patients with KOA in the community setting.

    The present study was performed in order to examine bone loss and calcium homeostasis in mice with glucocorticoid (GC)-induced osteoporosis (GIOP) following treatment with the aqueous extract of pomegranate seed (AE-PS). In addition, a comparative study with alendronate was performed. Biomarkers in the serum and the urine were measured. The tibias, kidney and duodenum were removed in order to measure the levels of bone calcium, protein expression as well as to perform histomorphological analysis of the bone. GC treatment facilitated the induction of hypercalciuria in the mice, and the AE-PS‑treated mice exhibited a greater increase in serum calcium and a decrease in urine calcium. The AE-PS reversed the deleterious effects on the trabecular bone induced by DXM and stimulated bone remodeling, including an increase in bone calcium and alkaline phosphatase‑b (ALP-b) and a decrease in a the critical bone resorption markers C-terminal telopeptide of type I collagen (CTX) and tartrate‑resistant acid phosphatase-5b (TRAP-5b). Hematoxylin and eosin (H&E) staining revealed the increased disconnections and separation between the growth plate and the trabecular bone network as well as the reduction in the trabecular bone mass of the primary and secondary spongiosa throughout the proximal metaphysis of the tibia in the DXM group. Moreover, the decreased protein expression of transient receptor potential vanilloid (TRPV)5, TRPV6 and calbindin‑D9k (CaBP‑9k) was reversed by the AE-PS or alendronate supplementation in the kidneys and the duodenum as well as plasma membrane Ca2+‑ATPase1 (PMCA1) expression in the kidneys of mice with GIOP. There was no marked difference in pharmacological effectiveness between alendronate and the AE-PS. Taken together, these findings suggest that the AE-PS may be an alternative therapy suitable for use in the management of secondary osteoporosis. PMID:27278225

  17. A randomized assessment of three quality of life (QOL) questionnaires for prostate cancer patients undergoing different radiation treatment modalities

    International Nuclear Information System (INIS)

    Purpose: The goal of this prospective, randomized study was to assess and compare compliance of patients diagnosed with prostate cancer to completing three different validated QOL instruments pre-treatment and six months later. Materials and Methods: Between April 2000 and April 2001, 124 patients were asked to fill out only one of three randomly selected QOL questionnaires (version A, B, C). Each addressed urinary and sexual function. One also addressed patients' physical, social, family, emotional, and functional well being. Study patients received External Beam Radiation Therapy (EBRT) or Brachytherapy (BRACHY), according to departmental policy. Exclusion criteria included current/previous hormone therapy and prostatectomy. Patients were asked to return the questionnaire at their first treatment visit. The three tools were: A The Functional Assessment of Cancer Therapy for Prostate Patients (FACT-P), The Sexual Adjustments Questionnaire (SAQ), and The American Urological Association (AUA) Questionnaire. The Fact-P questionnaire elicits information about physical, social, family, emotional, and functional well being as they relate to prostate cancer. SAQ focuses on sexual function; the AUA on urinary symptoms. B SAQ and AUA only; identical to Version A, but does not address physical, social, family, emotional, and functional well-being. C The International Prostate Symptom Score (I-PSS) Questionnaire, which addresses urinary symptoms and Patient Sexual Function Questionnaire, which focuses on erectile function. Additionally, patients were asked to respond yes/no to four variables designed to evaluate these questionnaires: 1) ease of understanding, 2) too personal, 3)addresses concerns regarding urinary function and sexual potency and 4) willingness to complete questionnaire in six months. These variables were examined for any trends that may exist between the different questionnaires. Results: Fifteen (12%) of the 124 patients returned incomplete questionnaires

    This prospective, cross-sectional study evaluated the impact of dysphagia on quality of life in healthy ageing and in subjects with Parkinson's disease (PD) using the Swallowing Quality of Life (SWAL-QOL) questionnaire. Sixteen healthy young adults (8 males, mean age = 25.1 years) and 16 healthy elders (8 males, mean age = 72.8 years) were recruited. Thirty-two subjects with idiopathic PD (mean age = 68.5 years) were recruited from a movement disorders clinic. The severity of PD was staged using the Hoehn and Yahr scale. Results revealed that elders experienced symptoms of dysphagia more frequently than young adults but the overall SWAL-QOL scores were not significantly different. Subjects with PD who experienced dysphagia reported greatly reduced QOL, and significant differences were found in all but one subsection of the SWAL-QOL. Disease progression detrimentally impacts QOL, with subjects in later-stage PD experiencing further reduction in the desire to eat, difficulty with food selection, and prolonged eating duration. These features, which increase with disease severity, are likely to impact negatively upon nutritional status, which is already under threat from PD-related dysphagia. PMID:19680723

    Modification of the lifestyle centering on dietary therapy has been proven to be effective for the treatment of diabetes mellitus, which is increasing progressively. However, lifetime treatment for diabetes inevitably puts economic as well as physical and mental burdens on the patients, and many patients drop out by discontinuing or neglecting treatment, promoting exacerbation of the condition. In this study, an original "Quality of life (QOL) questionnaire for patients with type II diabetes" using a visual analogue scale was tentatively prepared. To evaluate the reliability and validity of this questionnaire, 126 patients (64 males and 62 females) being treated as outpatients or inpatients at 8 university or public hospitals in Fukuoka Prefecture were selected at random, and valid answers from 73 patients were analyzed. From the 46 questions, those in which no significant correlation was observed or which were not answered by many patients were excluded. Since the value of sampling adequacy was 0.673 according to the Kaiser-Meyer-Olkin (KMO) measure, the sampling adequacy is considered to have been average. When factor analysis by varimax rotation was performed using the Statistical Package for Social Science, 4 factors consisting of 18 question items were extracted. Eventually, these 4 factors of 18 questions were adopted for the QOL questionnaire for patients with type II diabetes. The alpha values of the 4 factors were high at 0.867, 0.795, 0.706, and 0.756. These results confirmed the internal consistency of the questionnaire and sufficient reliability of this analytical method. PMID:18046991

    The maxillofacial prosthesis (MFP) is well accepted as one of the modalities to ameliolate the postsurgical crippling in the patients with maxillary malignancy. In this report, we analyzed 55 primary cases of MFP out of 100, from July, 1981 to July, 1987 in terms of the time of start after operation, and the duration and procedure of the MFP-making. MFP-making set about within 4 weeks in 35% of patients, 8 weeks in 25%, 12 weeks in 22%, and more than 12 weeks in 18%. The completion of MFP-making averaged 10 days. As a result of simplifying of MFP-making, we shortened a period requiring MFP-making within 3 days in recent 10 cases. There were no adverse effects of early wear of MFP after operation. We believe that early wear of MFP after operation improve the quality of life of patients with maxillary malignancy and considered that wear of MFP is not the completion of treatment, but is one of the procedures of treatment for the patients undergone maxillectomy.

    Quality of life (QoL) refers to the degree of satisfaction, or the sense of well being, people experience in organizations including universities. The quality of life students experience in a university increases when they believe their needs are aligned with the goals of the university because they perceive that the university is responsive to their needs. Quality of University Life (QuL) refers to the students' ability to stabilize their life regarding social activities, academic performance, health and spiritual. A study was undertaken to investigate the accountability of Universiti Teknologi MARA (UiTM), Malaysia, in terms of teaching and learning. The objective of this paper is to identify and evaluate the determinants of QoL and QuL measurement models. Data from 788 students who responded to a set of questionnaire were collected from nine faculties. Factor analysis performed on the data resulted in six determinants for QuL; friendly, skills, satisfaction, interest, learning and feeling. Only two determinants, environment and quality represented QoL. Results indicated that the measures were highly reliable (in terms of internal consistency) based on Cronbach Alpha values ranging from 0.705 to 0.905 for QuL and 0.826 to 0.888 for QoL. Construct validity was supported by Average Variance Extraction values of more than 0.5 for QuL (0.481 - 0.724) and QoL. (0.503 and 0.519). The construct reliability (CR) values ranging between 0.623 to 0.882 for QuL and 0.731 to 0.815 for QoL suggested good reliability construct.

    The purpose of this study was to develop alendronate (Aln)-eluting Ti substrates to induce osteogenic differentiation of human buccal fat cells (HBFCs). The surface of pristine Ti was modified by dopamine (DOPA) and then heparin was grafted onto the aminated Ti surfaces to achieve the Aln-eluting Ti system. Aln was subsequently immobilized on the surface of heparinized Ti (Hep-Ti). Pristine Ti and surface-modified-Ti were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and contact angle. Osteogenic differentiation of HBFCs on the surface of pristine-Ti, Hep-Ti, Aln (1 mg)/Hep-Ti, and Aln (5 mg)/Hep-Ti was demonstrated by alkaline phosphatase (ALP) activity, calcium deposition, and osteocalcin and osteopontin mRNA expression. Successful immobilization of Aln on Hep-Ti was confirmed by XPS and contact angle. Aln/Hep-Ti showed the sustained release for up to 28 days. Additionally, HBFCs cultured on Aln/Hep-Ti substrates showed significantly induced ALP activity, calcium deposition, and osteocalcin and osteopontin mRNA expression. These results suggest that Aln-eluting Ti substrates have a potential effect on osteogenic differentiation of HBFCs and will be a promising material for bone regeneration.

Forty postmenopausal Japanese women with osteoporosis or osteopenia and clinical risk factors for fractures (mean age: 75.4 years were analyzed; 33 patients were treated with alendronate and 7 were treated with alfacalcidol (ALF, controls in an outpatient clinic run by general practitioners. The metacarpal bone mineral density (BMD measured using a computed X-ray densitometer, urinary levels of cross-linked N-terminal telopeptides of type I collagen (NTX, and serum levels of alkaline phosphatase (ALP were monitored during the 5-year treatment period. The urinary NTX and serum ALP levels decreased significantly in the ALN group, compared with the ALF group. The metacarpal BMD was sustained in the ALN group but decreased significantly in the ALF group; the difference between these two groups was also significant. The present study evaluated the outcome of treatment with ALN for 5 years in postmenopausal Japanese women with osteoporosis or osteopenia and clinical risk factors for fractures. ALN successfully suppressed bone turnover and sustained the metacarpal BMD over the 5-year period of treatment in postmenopausal Japanese women with an increased risk of fractures.Keywords: alendronate, osteoporosis, osteopenia, risk factors for fractures, postmenopausal women

    Purpose Osteoporosis is a chronic disease and an important health and social burden due to its worldwide prevalence. Literature and clinical experience report incomplete adherence to the therapy. This retrospective observational study aimed at assessing the adherence to first-line antiosteoporosis drugs (AODs; reimbursed by the National Health System, according to the Italian Medicine Agency recommendation number 79), alendronate or risedronate, with or without calcium and/or vitamin D supplements, in a real, Italian clinical setting. Patients and methods Analyses were carried out on data present in the ARNO Observatory, a population-based patient-centric Italian database. From a population of 5,808,832 inhabitants with available data, a cohort of 3.3 million of patients aged ≥40 years was selected. New users of first-line AODs as monotherapy (accrual period, 2007–2009) were followed up over 3 years to assess adherence at 6, 12, and 36 months to AODs and to supplements and related determinants. Results Approximately 40,000 new users were identified: mostly women, aged on average (standard deviation) 71±10 years. Alendronate was the most prescribed (38.2% of patients), followed by risedronate (34.9%) and alendronate with colecalciferol as a fixed-dose combination (25.8%). Adherence at the 6-month follow-up was 54%, and this constantly and significantly decreased after 1 year to 46%, and after 3 years to 33% (P50 years were more likely to adhere to treatment regimen (P5 drugs), cardiovascular, and neurological therapies were significantly associated with low adherence throughout the follow-up period. Conclusion In a huge clinical practice sample, this study highlights suboptimal adherence to first-line AODs and to supplements and important determinants, such as concomitant therapies.

    The treatment of choice for tooth avulsion is replantation. The ideal replantation should be realized as quickly as possible, or at least, the avulsed tooth should be kept in an adequate solution to preserve the periodontal ligament attached to the root. If that is not possible, treatment of the radicular surface should be done in order to prevent radicular resorption. The purpose of this study was to test sodium alendronate as a substance for topical treatment of the radicular surface of avulsed teeth in an attempt to prevent the occurrence of dental resorptions. Fifty-four rat maxillary right central incisors were extracted and replanted. Group I--extra-alveolar dry period of 15 min, intracanal dressing with calcium hydroxide (CALEN, S.S. White, Artigos Dentários LTDA, Rio de Janeiro, Brazil) and replantation; Groups II and III - extra-alveolar dry periods of 30 and 60 min, respectively, immersion in 1% sodium hypochlorite for 30 min for removal of the periodontal ligament, washing in saline solution for 5 min, and treatment of the radicular surface with 3.2 mg/l sodium alendronate solution for 10 min. Intracanal dressing with calcium hydroxide and replantation followed. At 15, 60, and 90 days post-reimplantation, the animals were killed and the samples obtained and processed for microscopic analysis. The results indicated that sodium alendronate was able to reduce the incidence of radicular resorption, but not of dental ankylosis. No significant differences were observed regarding variations in the extra-alveolar periods among the groups. PMID:16422756

    International Nuclear Information System (INIS)

    Microspheric scaffolds of poly-(lactide-co-caprolactone) loaded with alendronate sodium, a family precursor of bisphosphonate drug and bioactive glass-ceramic (BGS) were prepared for the treatment of osteoporosis like bone defects with the rationale of getting a combined effect/concurrent advantage of osteoclast apoptosis as well as the augmentation of bone regeneration. The porous microspheres were generated by oil in water/solvent evaporation technique. The distribution of bioactive glass-ceramic was evidenced by the microcomputed tomography (μ-CT) and scanning electron microscopy analyses. The microspheres were evaluated for their in vitro cytocompatibility using L929 cell line and were found to be noncytotoxic. The osteoinductivity of the scaffold was assessed by its response in simulated body fluid and observed an excellent hydroxy carbonate apatite (HCA) layer formation on the surface which revealed the bone bonding and bone regeneration capability of the scaffold. The cell adhesion studies was performed with L-929 cell line and a marking cell growth on the surface as well as in the pores of the bioactive glass-ceramic as well as bioactive glass-ceramic cum drug incorporated microspheres was evidenced by the Confocal laser scanning microscopy (CLSM) investigation. No cell adhesion was observed onto the surface of the bare microspheres prepared by the copolymer alone where as the bioactive glass-ceramic and drug cum bioactive glass-ceramic loaded microspheres were found to promote the cell adhesion. The viability of the adhered cells on the microspheres was checked by flourescein diacetate (FDA) staining and it was observed that the adhered cells were viable and metabolically active. The release of the drug, alendronate sodium, directly into the problem site makes the presently prepared microsphere superior to the oral variety of drug available which is associated with oral discomfort and low bioavailability. - Highlights: ► Predicted model for osteoclast

    Chronic non-specific lung disease (CNSLD) encompasses asthma as well as chronic obstructive pulmonary disease (COPD). Recently in health care, there has been increasing awareness in the functional, psychological and social aspects of the health of patients; their quality of life (QOL). Quality-of-life research addressing CNSLD patients has been rather underdeveloped for a long period of time. Recently, however, the importance of QOL is being increasingly recognized, and several research groups have started to study QOL in CNSLD patients in more detail. This paper describes the construction of a disease-specific QOL instrument for patients with mild to moderately severe CNSLD. Items relating to several domains of QOL were listed, and 171 CNSLD patients in general practice were asked how much of a problem each item had been (assessed on a seven-point Likert scale). After applying an item-selection procedure, a uni-dimensional QOL questionnaire was constructed consisting of 55 items divided into seven domain subscales: breathing problems, physical problems, emotions, situations triggering or enhancing breathing problems, general activities, daily and domestic activities, and social activities, relationships and sexuality. Reliability estimates of the domain subscales of the constructed questionnaire varied from 0.68 to 0.89, and was 0.92 for the QOL for Respiratory Illness Questionnaire (QOL-RIQ) total scale. A first impression of the construct validity of the questionnaire was gained by investigation of the relationship between the QOL domain subscales and several indicators of illness severity, as well as the relative contribution of illness severity variables, background characteristics and symptoms to QOL, using regression analysis. Further research to validate the questionnaire to a greater extent (construct validity, test-retest reliability and responsiveness to change) is currently taking place. PMID:9176649

    Aim:To investigate the long-term effects of alendronate (Aln),a widely used oral bisphosphonate,on fracture healing and bone remodeling in ovariectomized rats.Methods:Adult female SD rats underwent ovariectomy,and then bilateral femoral osteotomy at 12 weeks post-ovariectomy.From d 2 post-ovariectomy,the animals were divided into 3 groups,and treated with Aln (3 mg·kg-1d-1,po) for 28 weeks (Aln/Aln),Aln for 12 weeks and saline for 16 weeks (Aln/Saline) or saline for 28 weeks (Saline/Saline).At 6 and 16 weeks post-fracture,the fracture calluses were examined with X-ray radiography,and biomechanical testing and histological analysis were performed.The calluses were labeled with tetracycline and calcein to evaluate the mineral apposition rate (MAR).Results:The fracture line was less distinct in the 2 Aln-treated groups at 6 weeks post-fracture,and disappeared in all the 3 groups at 16 weeks post-fracture.The size of the callus and radiographic density of the femora in the Aln/Aln group were the highest among the 3 groups at 6 and 16 weeks post-fracture.Similar results were observed in the ultimate load at failure and energy absorption.However,the treatment with Aln delayed endochondral ossification of the callus,and significantly increased the total sagittal-sectional area,percentage callus area and callus thickness,and decreased the MAR at 6 and 16 weeks post-fracture.Conclusion:In the ovariectomized rat model,Aln is beneficial for the mechanical properties of the callus,but delays callus remodeling by suppressing the remodeling of woven bone into lamellar bone.

    Full Text Available Recent studies indicated that alendronate enhanced osteogenesis in osteoblasts and human bone marrow-derived stem cells. However, the time- and dose-dependent effects of Aln on osteogenic differentiation and cytotoxicity of hBMSCs remain undefined. In present study, we investigated the effective dose range and timing of hBMSCs. hBMSCs were treated with various Aln doses (1, 5 and 10 µM according to the following groups: group A was treated with Aln during the first five days of bone medium, groups B, C and D were treated during the first, second, and final five days of osteo-induction medium and group E was treated throughout the entire experiment. The mineralization level and cytotoxicity were measured by quantified Alizarin Red S staining and MTT assay. In addition, the reversal effects of farnesyl pyrophosphate and geranylgeranyl pyrophosphate replenishment in group B were also investigated. The results showed that Aln treatment in groups A, B and E enhanced hBMSC mineralization in a dose-dependent manner, and the most pronounced effects were observed in groups B and E. The higher dose of Aln simultaneously enhanced mineralization and caused cytotoxicity in groups B, C and E. Replenishment of FPP or GGPP resulted in partial or complete reverse of the Aln-induced mineralization respectively. Furthermore, the addition of FPP or GGPP also eliminated the Aln-induced cytotoxicity. We demonstrated that hBMSCs are susceptible to 5 µM Aln during the initiation stage of osteogenic differentiation and that a 10 µM dose is cytotoxic.

    Similar efficacy of the cathepsin K inhibitor odanacatib (ODN) and the bisphosphonate alendronate (ALN) in reducing bone turnover markers and increasing bone mineral density in spine and hip were previously demonstrated in ovariectomized (OVX)-monkeys treated for 20 months in prevention mode. Here, we profiled RNA from tibial metaphysis and diaphysis of the same study using Affymetrix microarrays, and selected 204 probe sets (p < 0.001, three-group ANOVA) that were differentially regulated by ODN or ALN versus vehicle. Both drugs produced strikingly different effects on known bone-related genes and pathways at the transcriptional level. Although ALN either reduced or had neutral effects on bone resorption-related genes, ODN significantly increased the expression of osteoclast genes (eg, APC5, TNFRSF11A, CTSK, ITGB3, and CALCR), consistent with previous findings on the effects of this agent in enhancing the number of nonresorbing osteoclasts. Conversely, ALN reduced the expression of known bone formation-related genes (eg, TGFBR1, SPP1, RUNX2, and PTH1R), whereas ODN either increased or had neutral effects on their expression. These differential effects of ODN versus ALN on bone resorption and formation were highly correlative to the changes in bone turnover markers, cathepsin K (Catk) target engagement marker serum C-terminal cross-linked telopeptide (1-CTP) and osteoclast marker tartrate resistant acid phosphatase isoform 5b (TRAP5b) in the same monkeys. Overall, the molecular profiling results are consistent with the known pharmacological actions of these agents on bone remodeling and clearly differentiate the molecular mechanisms of ODN from the bisphosphonates. © 2016 American Society for Bone and Mineral Research.

    Full Text Available Abstract Background Atraumatic teeth extractions protocols are highly encouraged in patients taking bisphosphonates (Bps to reduce surgical trauma and, consequently, the risk of jaws osteonecrosis development. In this way, this paper aims to report the findings of increased surgical difficulty during simple exodontias in animals treated with bisphosphonates. Methods Sixty male Holtzman rats were randomly distributed into three groups of 20 animals and received daily subcutaneous administration of 1 mg/kg (AL1 or 3 mg/kg (AL3 of alendronate or saline solution (CTL. After 60 days of drug therapy all animals were submitted to first lower molars extractions under general anesthesia. Operatory surgical time and the frequency of teeth fractures were measured as principal outcomes and indicators of surgical difficulty degree. Results Animals treated with alendronate (AL1 and AL3 were associated to higher operatory times and increased frequency of teeth fractures compared to match controls. Conclusions The bisphosphonate therapy may be associated with an increased surgical difficulty and trauma following simple exodontias protocols, which is considered a critical issue when it comes to osteonecrosis development.

  17. The hydrogen sulfide donor, Lawesson's reagent, prevents alendronate-induced gastric damage in rats

    International Nuclear Information System (INIS)

    Our objective was to investigate the protective effect of Lawesson's reagent, an H2S donor, against alendronate (ALD)-induced gastric damage in rats. Rats were pretreated with saline or Lawesson's reagent (3, 9, or 27 µmol/kg, po) once daily for 4 days. After 30 min, gastric damage was induced by ALD (30 mg/kg) administration by gavage. On the last day of treatment, the animals were killed 4 h after ALD administration. Gastric lesions were measured using a computer planimetry program, and gastric corpus pieces were assayed for malondialdehyde (MDA), glutathione (GSH), proinflammatory cytokines [tumor necrosis factor (TNF)-α and interleukin (IL)-1β], and myeloperoxidase (MPO). Other groups were pretreated with glibenclamide (5 mg/kg, ip) or with glibenclamide (5 mg/kg, ip)+diazoxide (3 mg/kg, ip). After 1 h, 27 µmol/kg Lawesson's reagent was administered. After 30 min, 30 mg/kg ALD was administered. ALD caused gastric damage (63.35±9.8 mm2); increased levels of TNF-α, IL-1β, and MDA (2311±302.3 pg/mL, 901.9±106.2 pg/mL, 121.1±4.3 nmol/g, respectively); increased MPO activity (26.1±3.8 U/mg); and reduced GSH levels (180.3±21.9 µg/g). ALD also increased cystathionine-γ-lyase immunoreactivity in the gastric mucosa. Pretreatment with Lawesson's reagent (27 µmol/kg) attenuated ALD-mediated gastric damage (15.77±5.3 mm2); reduced TNF-α, IL-1β, and MDA formation (1502±150.2 pg/mL, 632.3±43.4 pg/mL, 78.4±7.6 nmol/g, respectively); lowered MPO activity (11.7±2.8 U/mg); and increased the level of GSH in the gastric tissue (397.9±40.2 µg/g). Glibenclamide alone reversed the gastric protective effect of Lawesson's reagent. However, glibenclamide plus diazoxide did not alter the effects of Lawesson's reagent. Our results suggest that Lawesson's reagent plays a protective role against ALD-induced gastric damage through mechanisms that depend at least in part on activation of ATP-sensitive potassium (KATP) channels

    Critical limb ischemia (CLI) has a poor prognosis and adversely affects patients’ quality of life (QOL). Therapeutic angiogenesis may improve mobility, mortality, and QOL in CLI patients. However, the effectiveness of gene therapy on such patients’ QOL is unknown. DVC1-0101, a non-transmissible recombinant Sendai virus vector expressing human fibroblast growth factor-2 gene, demonstrated safety and efficacy in a phase I/II study of CLI patients. We investigated the effects of DVC1-0101 on QOL in this cohort. QOL was assessed using the Short Form-36 health survey version 2 (SF-36) in 12 patients at pre-administration, 28 days, and 3, 6, and 12 months post-treatment. We examined differences between pre and post-administration QOL scores and correlations between QOL scores and vascular parameters. Patients demonstrated low baselines scores on every SF-36 dimension. Post-treatment scores showed significant improvements in physical functioning at 3 and 6 months (P < 0.05), role-physical at 3, 6, and 12 months (P < 0.05), bodily pain at 1, 3, 6, and 12 months (P < 0.05), vitality at 1, 6, and 12 months (P < 0.05), and physical component summary at 6 and 12 months (P < 0.05). DVC1-0101-based gene therapy may improve QOL in CLI patients over a 6-month period. PMID:27418463

    Exercise has established efficacy as an antidepressant in people with depression. However, few meta-analyses have assessed the effects of exercise across different domains of Quality of Life (QoL) in people with depression. Furthermore, there has been no previous meta-analysis of control group response in relation to QoL in exercise trials for depression. Randomized Clinical Trials(RCTs) were initially identified from a Cochrane review, and those including QoL assessments were included in the analysis. Search of major electronic databases were conducted to identify RCTs that compared the exercise effects on QoL versus control condition in people with depression. A random effects meta-analysis was employed to evaluate the Standardized Mean Difference (SMD). Six RCTs were included. Exercise significantly improved physical and psychological domains and overall QoL. Effects on social relationship and environment domains were not significant. No significant control group response was found for any domain or overall QoL. Exercise can be considered as a therapeutic strategy to improve physical and psychological domains and overall QoL of people with depression, with no effect evident across the social and environmental domains. The lack of improvement among control groups reinforces the role of exercise as a treatment for depression with benefits to QoL. PMID:27155287

  2. Validation of the quality of life-radiation therapy instrument (QOL-RTI) in patients receiving definitive radiation therapy for locally advanced prostate cancer

    International Nuclear Information System (INIS)

    Purpose/Objective: The incidence of prostate cancer has tripled over the last 10 years, doubled over the last four years and continues to increase. A common method of treating prostate cancer is with external beam radiotherapy with or without hormones. Accurate and comprehensive documentation through prospective studies with long term follow-up is necessary to reduce the negative impact of treatment on a patient's quality of life. While it is increasingly recognized that radiation therapy treatment for prostate cancer may result in permanent alteration of the patient's quality of life, the extent and timing of this change in quality of life has not been adequately investigated in a comprehensive and prospective manner. Furthermore, there are limited instruments developed for use with patients undergoing definitive radiotherapy. The purpose of this paper is to report on the validation of the Quality of Life Radiation Therapy Instrument (QOL-RTI), a 24-item visual analogue general quality of life tool developed for use with patients receiving radiotherapy. Materials and Methods: Health related quality of life was assessed in a prospective study of 62 patients treated with either combined hormonal therapy (HT) plus external beam radiotherapy (EBRT) or EBRT alone for locally advanced prostate cancer. Quality life was measured prospectively before, during, and after radiation therapy. Results: The estimated reliability of the subscales was assessed with coefficient alpha which ranged from 0.57 to 0.68. Internal consistency was calculated using initial questionnaires for the entire sample, yielding a Cronbach's alpha of 0.82. Test-retest produced a correlation coefficient of 0.75 (p<0.0001) [n=60]. Construct validity was assessed by a repeated measures design to look for time effect, group effect, group and time interaction effect. We examined quality of life total scores, subscale total scores and performance status scores for patients who were treated with HT+ EBRT and

    Actinic keratoses (AKs), especially on areas of the face, have a negative impact on a patient's quality of life (QoL). These lesions manifest on sun-damaged skin and have the potential to progress to squamous cell carcinoma. Field-directed therapy alone and in combination with lesion-directed treatment is effective in clearing both visible and nonvisible AK lesions. Topical treatments of AKs thus have the potential to improve a patient's well-being. However, evidence demonstrating improvements in patient QoL is limited, and is mostly based on observational or retrospective studies. Some prospective studies have reported unchanged or even worsening QoL despite excellent treatment outcomes. Our prospective, pilot study demonstrated a significant increase in QoL in 28 subjects with AKs of the face treated with ingenol mebutate gel 0.015%. QoL was assessed at days 0 and 60 using the Skindex-16 survey. Mean overall scores improved from 24.5% at baseline to 15.5% at day 60 (P=0.031). Improvements in QoL were consistent with an 80% reduction in AK lesion number at day 60. These improved QoL findings are in line with those from a recent retrospective study using ingenol mebutate 0.015% gel. This study therefore further demonstrates the potential for field therapy to improve both treatment outcomes and patient satisfaction. PMID:27143946

    Cathepsin K (CK), a lysosomal cysteine protease, is highly expressed in mature osteoclasts and degrades type 1 collagen. Odanacatib (ODN) is a selective and reversible CK inhibitor that inhibits bone loss in preclinical and clinical studies. Although an antiresorptive, ODN does not suppress bone formation, which led us to hypothesize that ODN may display restorative effect on the osteopenic bones. In a curative study, skeletally mature New Zealand rabbits were ovarectomized (OVX) and after induction of bone loss were given a steady-state exposure of ODN (9 mM/d) for 14 weeks. Sham-operated and OVX rabbits treated with alendronate (ALD), 17b-estradiol (E2), or parathyroid hormone (PTH) served as various controls. Efficacy was evaluated by assessing bone mineral density (BMD), bone microarchitecture (using micro-computed tomography), fluorescent labeling of bone, and biomechanical strength. Skeletal Ca/P ratio was measured by scanning electron microscopy (SEM) with X-ray microanalysis, crystallinity by X-ray diffraction, and bone mineral density distribution (tissue mineralization) by backscattered SEM. Between the sham and ODN-treated osteopenic groups, lumbar and femur metaphyseal BMD, Ca/P ratio, trabecular microstructure and geometric indices, vertebral compressive strength, trabecular lining cells, cortical parameters (femoral area and thickness and periosteal deposition), and serum P1NP were largely comparable. Skeletal improvements in ALD-treated or E2-treated groups fell significantly short of the sham/ODN/PTH group. However, the ODN group displayed reduced ductility and enhanced brittleness of central femur, which might have been contributed by higher crytallinity and tissue mineralization. Rabbit bone marrow stromal cells expressed CK and when treated with ODN displayed increased formation of mineralized nodules and decreased apoptosis in serum-deficient medium compared with control. In vivo, ODN did not suppress remodeling but inhibited osteoclast activity

A prospective open-labeled trial was conducted to compare the effects of short-term combined treatment with alendronate (ALN and ECT on bone mineral density (BMD and bone turnover with those of single treatment with ALN in postmenopausal women with osteoporosis. Two hundred and five postmenopausal osteoporotic women (mean age: 70 years were recruited in our outpatient clinic. Forty-six women with back pain were treated with ALN and ECT (intramuscular, 20 units a week, and 159 women without obvious back pain were treated with ALN alone. The lumbar BMD, urinary levels of cross-linked N-terminal telopeptides of type I collagen (NTX, and serum levels of alkaline phosphatase (ALP were measured during the six-month treatment period. The baseline characteristics, except for age, body weight and number of patients with prevalent vertebral fractures, were not significantly different between the two groups. The mean increase rate in the lumbar BMD at six months was similar in the ALN (+4.41% and ALN+ECT (+5.15% groups, following similar reduction rates in urinary NTX levels (-40.2% and -43.0%, respectively, at three months and serum ALP levels (-19.0% and -19.7%, respectively, at six months. These results were consistent even after adjustments for age, body weight, and number of patients with prevalent vertebral fractures.

    We have reported our "new questionnaire of QOL (quality of life) in anti-emetic therapies during cancer chemotherapy" and demonstrated its reliability and validity. In the present study we investigated the utility of tropisetron capsules for delayed nausea and vomiting induced by cancer chemotherapies with CDDP single administration in a placebo-controlled double-blind comparative study using the questionnaire. The questionnaire was composed of the following scales: a physiological scale (appetite, feeling, vomiting, nausea), a psychological scale (sleep, mental fatigue, anxiety, pain, abdominal condition), a respiratory condition related scale (sputum, respiratory distress), an active scale (daily life in a hospital), a social relation scale (understanding of the family), a linear analogue scale for evaluation of the influence of nausea and vomiting in patient's life during 24 hours, and a face scale as the global scale. First, all patients were administered a preventive dose of tropisetron capsule on day 1 (the day of CDDP administration) and then allotted to once-daily oral administration of either a tropisetron (T group) or a placebo (P group) capsule during days 2 to 5 by a double-blind method. Chronological changes of QOL during the study period were measured by the area under the curve (AUC) generally used for calculation of blood levels of drugs. The maximum fluctuation (Difmax) of QOL scores throughout the whole study period was also evaluated. The data were collected from 114 cases, and 98 cases (51 in P group, 47 in T group) were analyzed. 1) The total score or 13 items (a modified linear analogue scale with 5 graduations), the face scale and linear analogue scale of T group were higher (better) than those of P group. 2) As for the total score of each scale, the physiological, psychological and active scales in the T group showed higher (better) levels than the P group. 3) As for the AUC values, the T group was lower (better) than the P group in most

    To establish whether biochemical markers could be used to monitor alendronate (ALN) treatment and predict long-term response in bone mass, we used results from an ongoing, randomized trial of ALN treatment for prevention of postmenopausal osteoporosis (n = 1202). In women treated with ALN (5 mg...... a 4- to 5-fold greater increase at month 24 in BMD in the tertiles, with the greatest decrease at month 6 in NTX or OC. In women treated with ALN (5 mg) who had a change at month 24 in spine BMD of at least 0%, 86% (NTX) and 79% (OC) had a decrease at month 6 of at least 40% (NTX) or 20% (OC......) (sensitivity). The corresponding specificities were 48% (NTX) and 53% (OC). In conclusion, change at month 6 in NTX and OC, in groups of women treated with ALN, indicated the numeric long-term response in BMD within these groups. In individual women, a decrease at month 6, in NTX or OC below the cut...

    Suramin sodium (SS), which can directly inhibit the committed step of Gsα activation, seems to be a promising drug for treating fibrous dysplasia (FD). Therefore, how to efficiently deliver SS to the lesion site becomes an urgent problem to be solved. Here a bone-targeted and pH-sensitive drug delivery system was constructed to deliver SS for treating FD with high efficiency. The novel type of bone-targeted cationic hyperbranched poly(amine-ester) (HBPAE) was synthesized by the proton-transfer polymerization of triethanolamine and glycidyl methacrylate, followed by surface carboxyl-modification and then conjugation of an alendronate (ALE) bone-targeting moiety. The resultant Suc-HBPAE-ALE formed nanoparticles in aqueous solution, and SS could be encapsulated into the Suc-HBPAE-ALE nanoparticles via electrostatic attraction. The dynamic light scattering (DLS) and transmission electron microscopy (TEM) assays showed that the SS-loaded nanoparticles had a spherical morphology with a mean diameter of 65 nm. The strong affinity of Suc-HBPAE-ALE nanoparticles to bone was verified by the hydroxyapatite (HA) adsorbing experiment. The therapeutic potential of the SS-loaded Suc-HBPAE-ALE nanoparticles was evaluated via the methylthiazoletetrazolium (MTT) assay and flow cytometry (FCM) analysis against FD cells. The experimental results indicated that the SS-loaded Suc-HBPAE-ALE nanoparticles were a highly promising drug delivery system with high efficiency for inhibiting the proliferation of diseased FD cells.

    The aim of this study was to investigate the drug distribution in ultra-high molecular weight polyethylene (UHMWPE) loaded with alendronate sodium (ALN), which was developed to treat particle-induced osteolysis after artificial joint replacements, since the drug distribution in UHMWPE could play a key role in controlling drug release. A mixture of UHMWPE powder and ALN was dried and hot pressed to prepare UHMWPE loaded with ALN (UHMWPE-ALN). Fourier transform infrared spectroscopy analysis demonstrated that the hot press had no effect on the functional groups of ALN in UHMWPE-ALN. X-ray diffraction indicated that there was no phase change of the UHMWPE after hot pressing. Time-of-flight secondary ion mass spectrometry (ToF-SIMS) spectra revealed the existence of characteristic elements and functional groups from ALN in UHMWPE-ALN, such as Na{sup +}, C{sub 3}H{sub 8}N{sup +}, PO{sup -}{sub 3} and PO{sub 3}H{sup -}. In addition, SIMS images suggested that ALN did not agglomerate in UHMWPE-ALN. A small punch test and hardness test were carried out and the results indicated that ALN did not affect the mechanical properties at the present content level. The present study demonstrated that it was feasible to fabricate the un-agglomerated distributed drug in UHMWPE with good mechanical properties. This ALN loaded UHMWPE would have potential application in clinics.

    A new questionnaire on QOL of patients with chemotherapy-induced emesis and vomiting was developed, and its reliability and validity were investigated in the present multi-center clinical trial. The questionnaire consisted of 15 items which included descriptive questions on appetite, feeling, sleep, mental fatigue, anxiety, pain, sputum, respiratory distress, nausea, vomiting, abdominal condition, daily life in a hospital and relationship with family, a linear analogue scale representing influence of nausea and vomiting on patient's life during 24 hours, and a face scale as the global scale. Data from 98 patients with cancer were analyzed by principal component analysis and correlation analysis. The results were summarized as follows: 1) Recollect rate was 78.1% and complete response rate was 86.0% in this QOL measurement. 2) A clear correlation was observed between appetite, feeling, nausea, vomiting and the physiological scale, between sleep, mental fatigue, anxiety, pain, abdominal condition and the psychological scale, between sputum, respiratory distress and the respiratory condition related scale, between daily life in hospital and the active scale, between relationship with family and the social relation scale. These results satisfied internal consistency. 3) As for test-retest reliability, the total score of 13 descriptive items between the day before and two days before the start of chemotherapy showed no significant difference. 4) The 13 items were grouped into physiological, the psychological, the respiratory condition related, the active and the social relation scales, and these scales belonged to a different dimension. 5) The linear analogue scale, the face scale and the total scores of 13 descriptive items correlated respectively with all of items except item of, relationship with family. 6) As for concurrent validity, vomiting frequency, severity of nausea and anorexia correlated with the physiological scale. Severity of nausea and anorexia also

    Full Text Available OBJETIVO: Analisar, por meio da histomorfometria, o efeito do alendronato de sódio sobre o trabeculado ósseo de ratos, quando administrado simultaneamente com imobilização gessada. MÉTODOS: Foram utilizados quatro grupos com cinco fêmeas de ratos Wistar: 1 imobilizado; 2 não imobilizado + alendronato; 3 imobilizado + alendronato; e 4 controle. A imobilização foi feita com gesso pelvipodálico aplicado até o membro posterior direito e o alendronato foi administrado em doses semanais. O período de observação foi de 28 dias e realizada histomorfometria da metáfise proximal da tíbia, com análise do número de trabéculas, volume ósseo, espessura trabecular e separação trabecular. RESULTADOS: O grupo imobilizado apresentou volume ósseo menor que os demais grupos. Os animais que receberam alendronato semanal, tanto imobilizados, quanto não imobilizados, apresentaram volume ósseo maior que o controle. A espessura trabecular no grupo imobilizado foi menor do que nos grupos controle e não imobilizado que recebeu alendronato, mas não apresentou diferença significativa em relação ao imobilizado com alendronato. O grupo imobilizado apresentou separação trabecular maior que os demais grupos. Os grupos não imobilizado, sem imobilização que recebeu alendronato e imobilizado que recebeu alendronato apresentaram aumento no número de trabéculas em relação ao grupo imobilizado. CONCLUSÃO: A imobilização empregada efetivamente levou à osteopenia, verificada pela diminuição de todos os principais parâmetros histomorfométricos estudados. Estas alterações foram prevenidas pela administração concomitante de alendronato sódico, exceto com relação à espessura trabecular. O alendronato de sódio foi capaz de aumentar os parâmetros morfométricos, mesmo em animais não imobilizados.OBJECTIVE: Using histomorphometric means to analyze the effect of alendronate sodium on the bone trabeculate of rats administered

Compliance was calculated as the sum of prescription durations for all prescriptions for each patient over 1 year. Persistence was calculated as the time between first and last prescriptions over 2 years (1 year for deferasirox and desferrioxamine. Data from Germany and the UK were available and used for analysis.Results: Incremental improvements in compliance were +30% in the UK and +26% in Germany for alendronate once weekly vs once daily, +14% in the UK and +19% in Germany for extended-release vs immediate-release methylphenidate, and +15% in Germany for desferrioxamine vs deferasirox. Incremental improvements in persistence were +9 months in the UK and +8 months in Germany for alendronate once weekly vs once daily, +4 months in the UK and +3 months in Germany for extended-release vs immediate-release methylphenidate, and +2 months in Germany for deferasirox vs desferrioxamine.Conclusion: The new formulations that we evaluated were associated with better compliance and persistence compared with older formulations. Despite the fact that some sources of bias could not be excluded, it is likely that these improvements can be attributed to the lower treatment burdens of the galenic formulations of the drugs considered

  5. Persistence of 1,25D-induced hypercalciuria in alendronate-treated genetic hypercalciuric stone-forming rats fed a low-calcium diet.

    Genetic hypercalciuric stone-forming (GHS) rats demonstrate increased intestinal Ca absorption, increased bone resorption, and reduced renal tubular Ca reabsorption leading to hypercalciuria and all form kidney stones. GHS have increased vitamin D receptors (VDR) at these sites of Ca transport. Injection of 1,25(OH)2D3 (1,25D) leads to a greater increase in urine (u)Ca in GHS than in control Sprague-Dawley (SD), possibly due to the additional VDR. In GHS the increased uCa persists on a low-Ca diet (LCD) suggesting enhanced bone resorption. We tested the hypothesis that LCD, coupled to inhibition of bone resorption by alendronate (alen), would eliminate the enhanced 1,25D-induced hypercalciuria in GHS. SD and GHS were fed LCD and half were injected daily with 1,25D. After 8 days all were also given alen until euthanasia at day 16. At 8 days, 1,25D increased uCa in SD and to a greater extent in GHS. At 16 days, alen eliminated the 1,25D-induced increase in uCa in SD. However, in GHS alen decreased, but did not eliminate, the 1,25D-induced hypercalciuria, suggesting maximal alen cannot completely prevent the 1,25D-induced bone resorption in GHS, perhaps due to increased VDR. There was no consistent effect on mRNA expression of renal transcellular or paracellular Ca transporters. Urine CaP and CaOx supersaturation (SS) increased with 1,25D alone in both SD and GHS. Alen eliminated the increase in CaP SS in SD but not in GHS. If these results are confirmed in humans with IH, the use of bisphosphonates, such as alen, may not prevent the decreased bone density observed in these patients. PMID:24573387

    This is a preplanned subgroup analysis on 318 patients with glucocorticoid-induced osteoporosis (GIOP) from an open, prospective, multi-centered, uncontrolled study on a large cohort of elderly patients with a high risk of falls and fractures. The entire group of 2579 patients was recruited by 818 practicing physicians and treated for three months with a new combination package containing 4 or 12 self-explanatory one-week blisters, each with one tablet of 70 mg alendronate (CAS 260055-05-8) and 7 capsules of 1 pg alfacalcidol (CAS 41294-56-8) (Tevabone"). The average age of the GIOP patients was 71 years and the mean body mass index 26.7 kg/m2. 58% had a diagnosis of increased risk of falls, prevalent vertebral and non-vertebral fractures were documented in 70% and 65% of the patients, respectively, and a creatinine clearance (CrCl) below 65 ml/min was documented in 55 %. Main outcome parameters were the Chair Rising Test (CRT), Timed Up and Go Test (TUG), back pain and safety at onset and after 3 months. In addition, an evaluation of the package design was done at the end of the study. The percentage of patients able to perform the CRT within 10 sec increased from 21.1% to 39.4% after 3 months (increase 87%, p sec increased by 84% (p sec (p = 0.0025) (difference of 1.9 sec) and for the TUG the mean time decreased from 16.86 sec to 14.64 sec (p = 0.0056) (difference of 2.2 sec). Mean back pain measured by a 0-10 visual analogue scale decreased significantly by 43% from 6.0 to 3.4 (p compliance. This may contribute to the previously shown significant effect on reducing falls and fractures with the same regimen during a controlled long-term trial in primary osteoporosis. PMID:21428245

    There is little information on the effects of combination therapy for osteoporosis at the tissue level. Using quadruple tetracycline-labeled bone biopsies, we have compared the bone formation response to teriparatide (TPTD) in treatment-naïve subjects (Rx-Naïve) and in subjects on prior and ongoing alendronate (ALN) treatment (ALN-Rx). Three bone envelopes were analyzed: cancellous, endocortical, and intracortical. TPTD was given as a standard, continuous daily injection or as a cyclic regimen (3 months on daily TPTD, 3 months off, 3 months on daily TPTD). Subjects were biopsied at 7 weeks and at 7 months to allow comparison of the bone formation response to the first and second cycles of TPTD. Baseline values for dynamic bone formation indices were lower in ALN-Rx than Rx-Naïve subjects. Both Rx-Naïve and ALN-RX subjects responded to TPTD with significant increases in bone formation indices at both time points. With cyclic TPTD treatment, the first and second cycles of TPTD stimulated bone formation rate in the cancellous and endocortical envelopes to a similar extent in ALN-Rx and Rx-Naïve subjects. However, in Rx-Naïve patients, bone formation rate (BFR/BS) was higher in patients receiving daily treatment compared with those receiving cyclic TPTD treatment in all three envelopes in the 7-month biopsies. This suggests that the cyclic approach does not provide a skeletal benefit in treatment-naive patients. In the 7-month biopsies, cortical porosity was higher in the Rx-Naïve group receiving daily TPTD than in all other groups. These data provide supporting evidence at the tissue level for previous biochemical and densitometric data suggesting that addition of either cyclic or daily TPTD to ongoing ALN treatment may be an effective approach for patients with severe osteoporosis already treated with ALN who remain at high risk of fracture. © 2016 American Society for Bone and Mineral Research.

    Efficacy and safety of a new combination package containing 4 or 12 self-explanatory one-week blisters, each with one tablet of 70 mg alendronate (CAS 260055-05-8) and 7 capsules of 1 microg alfacalcidol (CAS 41294-56-8) (Tevabone) on muscle power, muscle function, balance and back pain was investigated in an open, multi-centered, uncontrolled, prospective study on a cohort of elderly patients with a high risk of falls and fractures. 818 practicing physicians all over Germany recruited 2579 patients for a 3-month observational trial being treated with the above combination package. 92.4% were women [89.7% of the women had postmenopausal osteoporosis (PMO)]. Their average age was 74.1 years and the mean body mass index 26.4 kg/m2. 55.4% had a history of falls. Prevalent vertebral and non-vertebral fractures were documented in 62.9% and 61.4% of the patients, respectively, and a creatinine clearance below 65 ml/min was documented in 65.5%. Main outcome parameters were the Chair Rising Test (CRT), Timed Up and Go Test (TUG), back pain and safety at onset and after 3 months. In addition an evaluation of the package design was done at the end of the study. The percentage of patients able to perform the CRT within 10 sec increased from 26.3% to 42.9% after 3 months (increase 63%, p sec of TUG increased by 54% (p sec (p sec (p sec in the performance of TUG results in a 24% increased risk for non-vertebral fractures. Mean back pain measured by a 0-10 visual analogue scale decreased significantly by 41% from 5.9 to 3.5 (p compliance. This may contribute to the previously shown significant effect on reducing falls and fractures with the same regimen during a controlled long-term trial. The same trend was found in all mentioned efficacy parameters and no different trend in safety in the large subgroup of 2106 women with documented PMO. PMID:21355445

    Evaluation of men with a point scale is a simple method that can be used both in primary care and specialist in-patient treatment. Although its use is not widespread. International scoring system for evaluation of symptoms of the prostate is common in Poland (IPSS). Responses to the questionnaire are the basis of IPSS scale. Quality of life form (QoL) is in addition to the scale of IPSS. It defines subjective assessment of patient well-being in case of symptoms of lower urinary tract at the same level as at the time of the study. 5-point questionnaire IIEF-5 has been used in Poland since 1999 to assess men's sexual life. The aim of the study is to compare the assessment of disuric disorders measured using the International Prostate System Score (IPSS) and Quality of Life scale versus scale of men's sexual self-esteem IIEF-5 in men at the age of 50-70. The study included 1746 randomly selected residents of the district Cracow-Downtown, at the age of 50-70. Medical interview was carried out (including complaints of lower urinary tract symptoms (IPSS), quality of life (QoL) and sexual dysfunction (IIEF-5); physical examination with assessment of individual systems with particular emphasis on genitourinary system, physical examination of the prostate (DRE), PSA level in total and free fractions, a biopsy of the prostate under ultrasound control if necessary. For the analysis qualified 1746 men. The men were divided into groups called groups of disease: a suspicion of prostate cancer, can not rule out prostate cancer, prostate cancer confirmed, probable benign prostatic hyperplasia (BPH), no lesions. The largest was the group with probable benign prostatic hyperplasia 64.89% of the total respondents, followed by a group of men without lesions, 26.29%, a group of probable prostate cancer was 6.41% of the respondents, a group with whom you can not rule out prostate cancer was 1.89%, the smallest was the group with confirmed prostate cancer, 0.52% of all male respondents

    Boehncke et al. suggested that decorative cosmetics can improve the quality of life (QOL) of skin diseases. But dermatologists sometimes discourage female acne patients from applying make-up since decorative cosmetics are considered one of the aggravating factors for acne eruptions. The purpose of this study is to assess whether make-up application interferes with acne treatments and how QOL changes when the make-up items are designed for acne patients and used in order to disguise acne eruptions. Eighteen female acne patients were trained by a make-up artist and advised to apply acne-designed basic and decorative cosmetics for 2 to 4 weeks while their acne was appropriately treated. The acne-severity and QOL of patients were assessed before and after the study. The results revealed that the number of acne eruptions decreased even though patients were applying make-up. The QOL scores of Skindex-16, GHQ30 and anxiety state index greatly improved. Our results suggest that dermatologists should encourage acne patients to utilize appropriate make-up to improve their QOL. PMID:16048760

    The objective of this study is to assess swallowing and speech outcome after chemoradiation therapy for head and neck cancer, based on the patient-reported outcome measures Swallowing Quality of Life Questionnaire (SWAL-QOL) and Speech Handicap Index (SHI), both provided with cut-off scores. This is a cross-sectional study. Department of Otolaryngology/Head and Neck Surgery of a University Medical Center. Sixty patients, 6 months to 5 years after chemoradiation for head and neck squamous cell carcinoma. Swallowing Quality of Life Questionnaire (SWAL-QOL) and SHI, both validated in Dutch and provided with cut-off scores. Associations were tested between the outcome measures and independent variables (age, gender, tumor stage and site, and radiotherapy technique, time since treatment, comorbidity and food intake). Fifty-two patients returned the SWAL-QOL and 47 the SHI (response rate 87 and 78 %, respectively). Swallowing and speech problems were present in 79 and 55 %, respectively. Normal food intake was noticed in 45, 35 % had a soft diet and 20 % tube feeding. Patients with soft diet and tube feeding reported more swallowing problems compared to patients with normal oral intake. Tumor subsite was significantly associated with swallowing outcome (less problems in larynx/hypopharynx compared to oral/oropharynx). Radiation technique was significantly associated with psychosocial speech problems (less problems in patients treated with IMRT). Swallowing and (to a lesser extent) speech problems in daily life are frequently present after chemoradiation therapy for head and neck cancer. Future prospective studies will give more insight into the course of speech and swallowing problems after chemoradiation and into efficacy of new radiation techniques and swallowing and speech rehabilitation programs.

Our objective was, therefore, to summarize studies addressing the impact of telehealth on QoL in patients with COPD.Design: Systematic review.Methods: A series of systematic searches were carried out using the following databases: PubMed, EMBASE, Cochrane Controlled Trials Register, and Clinical Trials.gov (last updated November 2015. A predefined search algorithm was utilized with the intention to capture all results related to COPD, QoL, and telehealth published since year 2000.Outcome measures: Primary outcome was QoL, assessed by validated measures.Results: Out of the 18 studies fulfilling the criteria for inclusion in this review, three studies found statistically significant improvements in QoL for patients allocated to telemedical interventions. However, all of the other included studies found no statistically significant differences between control and telemedical intervention groups in terms of QoL.Conclusion: Telehealth does not make a strong case for itself when exclusively looking at QoL as an outcome, since statistically significant improvements relative to control groups have been observed only in few of the available studies. Nonetheless, this does not only rule out the possibility that telehealth is superior to standard care with regard to other outcomes but also seems to call for more research, not least in large-scale controlled trials.

    Odanacatib (ODN) is a selective and reversible Cathepsin K (CatK) inhibitor currently being developed as a once weekly treatment for osteoporosis. Here, effects of ODN compared to alendronate (ALN) on bone turnover, DXA-based areal bone mineral density (aBMD), QCT-based volumetric BMD (vBMD) and geometric parameters were studied in ovariectomized (OVX) rhesus monkeys. Treatment was initiated 10 days after ovariectomy and continued for 20 months. The study consisted of four groups: L-ODN (2 mg/kg, daily p.o.), H-ODN (8/4 mg/kg daily p.o.), ALN (15 μg/kg, twice weekly, s.c.), and VEH (vehicle, daily, p.o.). L-ODN and ALN doses were selected to approximate the clinical exposures of the ODN 50-mg and ALN 70-mg once-weekly, respectively. L-ODN and ALN effectively reduced bone resorption markers uNTx and sCTx compared to VEH. There was no additional efficacy with these markers achieved with H-ODN. Conversely, ODN displayed inversely dose-dependent reduction of bone formation markers, sP1NP and sBSAP, and L-ODN reduced formation to a lesser degree than ALN. At month 18 post-OVX, L-ODN showed robust increases in lumbar spine aBMD (11.4%, p<0.001), spine trabecular vBMD (13.7%, p<0.001), femoral neck (FN) integral (int) vBMD (9.0%, p<0.001) and sub-trochanteric proximal femur (SubTrPF) int vBMD, (6.4%, p<0.001) compared to baseline. L-ODN significantly increased FN cortical thickness (Ct.Th) and cortical bone mineral content (Ct.BMC) by 22.5% (p<0.001) and 21.8% (p<0.001), respectively, and SubTrPF Ct.Th and Ct.BMC by 10.9% (p<0.001) and 11.3% (p<0.001) respectively. Compared to ALN, L-ODN significantly increased FN Ct. BMC by 8.7% (p<0.05), and SubTrPF Ct.Th by 7.6% (p<0.05) and Ct.BMC by 6.2% (p<0.05). H-ODN showed no additional efficacy compared to L-ODN in OVX-monkeys in prevention mode. Taken together, the results from this study have demonstrated that administration of ODN at levels which approximate clinical exposure in OVX-monkeys had comparable efficacy to ALN in

    Full Text Available Gregory J FeldmanS Carolina Pharmaceutical Research, Alliance Biomedical Group International, Spartanburg, SC, USAAbstract: Chronic obstructive pulmonary disease (COPD is a common disease in the general population and it places a considerable burden on patients, with the disease negatively affecting quality of life. In practice, patients with COPD generally seek medical attention because of symptoms, particularly breathlessness, and the resulting physical limitations, which affect the health-related quality of life (HR-QOL in patients. The defining feature of COPD is airflow limitation that causes air trapping and increased hyperinflation as the ventilation rate increases during physical effort. Hyperinflation causes or worsens breathlessness as breathing becomes inefficient, with the end result being an avoidance of physical exertion and a cycle of increasing dyspnea caused by inactivity and deconditioning, with deleterious effects on HR-QOL. Current published guidelines for COPD state that the goals of pharmacologic therapy should be to control symptoms, improve health status and exercise tolerance, and reduce the frequency of COPD exacerbations. Effective and sustained bronchodilation has emerged as a key strategy for improving dyspnea and ability to exercise. As there is no cure for COPD, a major goal of treatment and of research into new therapies is to improve HR-QOL in COPD patients.Conclusion: More recently, indacaterol, an inhaled ultra-long-acting β2-agonist (24-hour action, has been approved in many countries at different doses (between 75 and 300 µg once daily for treatment of patients with stable but symptomatic COPD. The aim of this review was to explore once-daily indacaterol clinical data as related to improvement in HR-QOL in COPD. Indacaterol studies have shown significant improvements in lung function of COPD patients, and these improvements have also translated into clinically meaningful improvements in patient symptoms and

    Full Text Available Background: To investigate the improvement in quality of life (QoL of alcohol-dependent patients during a 3-week inpatient withdrawal programme, and to identify the sociodemographic, clinical and alcohol-related variables associated with baseline QoL on admission and with improvement of QoL during residential treatment. Methods: This prospective, observational study included 414 alcohol-dependent patients, hospitalised for a period of 3 weeks. QoL was measured on admission and at discharge using the French version of the Medical Outcome Study SF-36. The mean scores for each dimension and for the Physical and Mental Component Summary scores were calculated. Results: The mean scores per dimension and the mean Physical and Mental Component Summary scores were significantly lower on admission than at discharge; the lowest scores being observed for social functioning and role limitations due to emotional problems. At discharge, the mean scores per dimension were similar to those observed in the French general population. Female gender, age >45 years, living alone, working as a labourer or employee, somatic comorbidity, and the existence of at least five criteria for alcohol dependence according to the DSM-IV classification were associated with a low Physical Component Summary score on admission; psychiatric comorbidity, the presence of at least five DSM-IV dependence criteria, smoking and suicidality were associated with a low Mental Component Summary score on admission. The increase in Physical and Mental Component Summary scores during hospitalisation was more marked when the initial scores were low. Apart from the initial score, the greatest improvement in Physical Component Summary score was seen in patients with a high alcohol intake and in those without a somatic comorbidity; the increase in Mental Component Summary score was greatest in patients without psychotic symptoms and in those who abused or were dependent on illegal drugs.

    Background Cancer patients suffer from diverse symptoms, including depression, anxiety, pain, and fatigue and lower quality of life (QoL) during disease progression. This study aimed to evaluate the benefits of Traditional Chinese Medicine psycho-behavioral interventions (TCM PBIs) on improving QoL by meta-analysis. Methods Electronic literature databases (PubMed, CNKI, VIP, and Wanfang) were searched for randomized, controlled trials conducted in China. The primary intervention was TCM PBIs. The main outcome was health-related QoL (HR QoL) post-treatment. We applied standard meta analytic techniques to analyze data from papers that reached acceptable criteria. Results The six TCM PBIs analyzed were acupuncture, Chinese massage, Traditional Chinese Medicine five elements musical intervention (TCM FEMI), Traditional Chinese Medicine dietary supplement (TCM DS), Qigong and Tai Chi. Although both TCM PBIs and non-TCM PBIs reduced functional impairments in cancer patients and led to pain relief, depression remission, reduced time to flatulence following surgery and sleep improvement, TCM PBIs showed more beneficial effects as assessed by reducing both fatigue and gastrointestinal distress. In particular, acupuncture relieved fatigue, reduced diarrhea and decreased time to flatulence after surgery in cancer patients, while therapeutic Chinese massage reduced time to flatulence and time to peristaltic sound. Conclusion These findings demonstrate the efficacy of TCM PBIs in improving QoL in cancer patients and establish that TCM PBIs represent beneficial adjunctive therapies for cancer patients.

    Full Text Available FUNDAMENTO: A hipertensão arterial é uma desordem caracterizada por alterações relevantes no tecido ósseo. O alendronato sódico tem indicação no tratamento de doenças ósseas, por causa de sua afinidade pela hidroxiapatita, inibindo as reabsorções ósseas. OBJETIVO: Analisar a ação local do alendronato sódico na reparação óssea de ratos espontaneamente hipertensos (SHR. MÉTODOS: Um defeito ósseo foi criado no fêmur esquerdo de 80 ratos. De acordo com o material utilizado no local, criaram-se quatro grupos: controle (C, amido (Am, alendronato 1 mol (A1 e alendronato 2 mol (A2. Após 7 e 21 dias, os animais foram sacrificados. Foram realizadas análises histológicas e histomorfométricas e os dados foram submetidos a análise de variância (ANOVA e teste de Tukey (5%. RESULTADOS: Aos 7 dias, observou-se, na área do defeito, tecido conjuntivo com hemorragia e inflamação em todos os grupos. Alguns apresentavam matriz osteóide. Os grupos A1 e A2 apresentaram, ainda, uma rede de fibrina. Aos 21 dias, as trabéculas ósseas fechavam praticamente a extensão do defeito nos grupos C e Am. No grupo A1 de animais machos, observaram-se trabéculas que se irradiavam do canal medular até a área do defeito. Nos grupos A1 e A2, constatou-se apenas a presença de tecido conjuntivo com mínima deposição de osteóide. Um achado histológico marcante foi a formação de tecido ósseo extracortical subperiosteal nos animais dos grupos A1 e A2. CONCLUSÃO: Concluiu-se que a administração do alendronato sódico não contribuiu para o reparo ósseo nos ratos SHR, mas possivelmente tenha sido responsável pelas formações ósseas extracorticais observadas.BACKGROUND: The arterial hypertension is a disorder characterized by relevant alterations in the bone tissue.

Sudarshan Kriya yoga (SKY intervention is acknowledged for its positive impact on health. It is hypothesised that SKY would improve PLHIV′s QOL, justifying an evaluation. Methods: In this open label randomized controlled pilot trial, 61 adult PLHIV with CD4 count more than 400 cells/µl and Karnofsky scale score above 70 were enrolled. Those with cardiac disease, jaundice, tuberculosis, or on antiretroviral therapy/yoga intervention were excluded. All were given standard care, randomized to SKY intervention (31: I-SKY and only standard of care in control (30: O-SOC arms. The I-SKY participants were trained for six days to prepare for daily practice of SKY at home for 30 min. A validated 31-item WHOQOL-HIVBREF questionnaire was used to document effect in both arms from baseline to three visits at 4 wk interval. Results: Baseline QOL scores, hypertension and CD4 count were similar in both arms. An overall 6 per cent improvement of QOL scores was observed in I-SKY group as compared to O-SOC group, after controlling for baseline variables like age, gender, education and occupation ( p0 =0.016; 12 per cent for physical ( p0 =0.004, 11 per cent psychological ( p0 =0.023 and 9 per cent level of independence ( p0 =0.001 domains. Improvement in I-SKY observed at post-training and in the SKY adherence group showed increase in these two domains. Conclusions: A significant improvement in QOL scores was observed for the three health related QOL domains in SKY intervention arm. This low cost strategy improved physical and psychological state of PLHIV calling for upscaling with effective monitoring for sustainability of quality of life.

    Full Text Available Bisphosphonates are currently used in the treatment of many diseases involving increased bone resorption such as osteoporosis. Statins have been widely used for the treatment of hypercholesterolemia and recent studies have shown that these drugs are also capable of stimulating bone formation. The purpose of this study was to evaluate the influence of an estrogen deficient state and the effects of simvastatin and sodium alendronate therapies on alveolar bone in female rats. Fifty-four rats were either ovariectomized (OVX or sham operated. A month later, the animals began to receive a daily dose of simvastatin (SIN - 25 mg/kg, sodium alendronate (ALN - 2 mg/kg or water (control orally. Thirty-five days after the beginning of the treatment, the rats were sacrificed and their left hemimandibles were removed and radiographed using digital X-ray equipment. The alveolar radiographic density under the first molar was determined with gray-level scaling and the values were submitted to analysis of variance (a = 5%. Ovariectomized rats gained more weight (mean ± standard deviation: 20.06 ± 6.68% than did the sham operated animals (12.13 ± 5.63%. Alveolar radiographic density values, expressed as gray levels, were lowest in the OVX-water group (183.49 ± 6.47, and differed significantly from those observed for the groups receiving alendronate (sham-ALN: 193.85 ± 3.81; OVX-ALN: 196.06 ± 5.11 and from those of the sham-water group (193.66 ± 4.36. Other comparisons between groups did not show significant differences. It was concluded that the ovariectomy reduced alveolar bone density and that alendronate was efficient for the treatment of this condition.Os bisfosfonatos são empregados atualmente para o tratamento de várias doenças caracterizadas pelo aumento da reabsorção óssea, como a osteoporose. As estatinas são amplamente utilizadas para redução de níveis elevados de colesterol e estudos recentes têm revelado sua ação anabólica no osso

    Purpose: Anatomic and dosimetric changes have been reported during intensity modulated radiation therapy (IMRT) in patients with nasopharyngeal carcinoma (NPC). The purpose of this study was to evaluate the effects of replanning on quality of life (QoL) and clinical outcomes during the course of IMRT for NPC patients. Methods and Materials: Between June 2007 and August 2011, 129 patients with NPC were enrolled. Forty-three patients received IMRT without replanning, while 86 patients received IMRT replanning after computed tomography (CT) images were retaken part way through therapy. Chinese versions of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and Head and Neck Quality of Life Questionnaire 35 were completed before treatment began and at the end of treatment and at 1, 3, 6, and 12 months after the completion of treatment. Overall survival (OS) data were compared using the Kaplan-Meier method. Results: IMRT replanning had a profound impact on the QoL of NPC patients, as determined by statistically significant changes in global QoL and other QoL scales. Additionally, the clinical outcome comparison indicates that replanning during IMRT for NPC significantly improved 2-year local regional control (97.2% vs 92.4%, respectively, P=.040) but did not improve 2-year OS (89.8% vs 82.2%, respectively, P=.475). Conclusions: IMRT replanning improves QoL as well as local regional control in patients with NPC. Future research is needed to determine the criteria for replanning for NPC patients undergoing IMRT.

    Full Text Available Cardiac Syndrome X (CSX was considered a stable coronary syndrome, yet due to its nature, CSX symptoms often have a great impact on patients’ Quality of Life (QoL. According to ESC 2013 stable coronary artery disease criteria, CSX was replaced by Microvascular Angina (MA.Unfortunately, most CSX or MA patients, after classical angina (involving main coronary vessels has been ruled out, often do not receive proper treatment. Indications for pharmacological treatment of MA patients were introduced only recently. Another problematic issue is that scientists describing the pathophysiology of both CSX and MA stress a lack of a deeper insight into the multifactorial etiology of the source of pain associated with this disease. In the presented article we have attempted to study the influence of cardiac rehabilitation (3 months programme on the QoL of patients recognized as suffering from MA, as well as to check if changes in myocardial perfusion in these patients at baseline and after completion of cardiac rehabilitation match changes in their QoL. Therefore, after screening 436 women for MA, we studied 55 of them who were confirmed as having MA and who agreed to participate in the study. Exercise tests, Myocardial Perfusion Imaging, and QoL questionnaires were studied at baseline and after completing 3 months period of cardiac rehabilitation. Results were subsequently compared, which showed a link between improved perfusion score in SPECT study and improved overall physical capacity, on one hand, and improved QoL score on the other. These results confirm that cardiac rehabilitation is a very useful treatment option for MA patients. It seems that training during cardiac rehabilitation is a very important factor (improved physical efficiency –> increase in self-belief, and that taking into consideration the multifactor pathophysiology of pain, it is connected with a better quality of life for MA patients.

    Translational evaluation of disease progression and treatment response is critical to the development of therapies for osteoporosis. In this study, longitudinal in-vivo monitoring of odanacatib (ODN) treatment efficacy was compared to alendronate (ALN) in ovariectomized (OVX) non-human primates (NHPs) using high-resolution peripheral computed tomography (HR-pQCT). Treatment effects were evaluated using several determinants of bone strength, density and quality, including volumetric bone mineral density (vBMD), three-dimensional structure, finite element analysis (FEA) estimated peak force and biomechanical properties at the ultradistal (UD) radius at baseline, 3, 6, 9, 12, and 18 months of dosing in three treatment groups: vehicle (VEH), low ODN (2 mg/kg/day, L-ODN), and ALN (30 μg/kg/week). Biomechanical axial compression tests were performed at the end of the study. Bone strength estimates using FEA were validated by ex-vivo mechanical compression testing experiments. After 18months of dosing, L-ODN demonstrated significant increases from baseline in integral vBMD (13.5%), cortical thickness (24.4%), total bone volume fraction BV/TV (13.5%), FEA-estimated peak force (26.6%) and peak stress (17.1%), respectively. Increases from baseline for L-ODN at 18 months were significantly higher than that for ALN in DXA-based aBMD (7.6%), cortical thickness (22.9%), integral vBMD (12.2%), total BV/TV (10.1%), FEA peak force (17.7%) and FEA peak stress (11.5%), respectively. These results demonstrate a superior efficacy of ODN treatment compared to ALN at the UD radii in ovariectomized NHPs. PMID:23791777

The aim of the present clinical practice-based observational study was to examine the influence of ALN treatment for 1 year on the speed of sound (SOS of the calcaneus and bone turnover markers in postmenopausal Japanese women with osteoporosis.Patients and methods: Forty-five postmenopausal Japanese women with osteoporosis who had received treatment with ALN for more than 1 year were enrolled in the study. The SOS and bone turnover markers were monitored over 1 year of ALN treatment.Results: The urinary levels of cross-linked N-terminal telopeptides of type I collagen and serum levels of alkaline phosphatase decreased significantly from the baseline values (–44.9% at 3 months and –22.2% at 12 months, respectively. The SOS increased modestly, but significantly, from the baseline value (0.6% at both 6 and 12 months. The percentage decrease in the urinary levels of cross-linked N-terminal telopeptides of type I collagen at 3 months was significantly correlated with the percentage increase in the SOS only at 6 months (correlation coefficient, 0.299.Conclusion: The present study confirmed that ALN treatment suppressed bone turnover, producing a clinically significant increase in the SOS of the calcaneus in postmenopausal Japanese women with osteoporosis.Keywords: postmenopausal osteoporosis, quantitative ultrasound (QUS, SOS, bone turnover, biochemical markers

    Objective. To investigate the effects of sitting Tai Chi on muscle strength, balance control, and quality of life (QOL) among survivors with spinal cord injuries (SCI). Methods. Eleven SCI survivors participated in the sitting Tai Chi training (90 minutes/session, 2 times/week for 12 weeks) and eight SCI survivors acted as controls. Dynamic sitting balance was evaluated using limits of stability test and a sequential weight shifting test in sitting. Handgrip strength was also tested using a hand-held dynamometer. QOL was measured using the World Health Organization's Quality of Life Scale. Results. Tai Chi practitioners achieved significant improvements in their reaction time (P = 0.042); maximum excursion (P = 0.016); and directional control (P = 0.025) in the limits of stability test after training. In the sequential weight shifting test, they significantly improved their total time to sequentially hit the 12 targets (P = 0.035). Significant improvement in handgrip strength was also found among the Tai Chi practitioners (P = 0.049). However, no significant within and between-group differences were found in the QOL outcomes (P > 0.05). Conclusions. Twelve weeks of sitting Tai Chi training could improve the dynamic sitting balance and handgrip strength, but not QOL, of the SCI survivors. PMID:25688276

Materials and Methods: RAW264.7 macrophages and UMR106 osteoblasts were co-cultured for 8 days, with BSA or AGEs (50-200 µg/ml, with or without Alendronate (10-8-10-4M. The effect of these culture conditions on Oc formation was evaluated (number of Oc, cell-associated tartrate-resistant acid phosphatase [TRAP] activity, as well as Oc expression of RAGE (receptor for AGEs, and osteoblastic expression of RANK ligand (RANKL. These last two parameters were evaluated by indirect immunofluorescence, in order to estimate the expression and sub-cellular distribution of both membrane-associated proteins. Results: AGEs (50-200 µg/ml dose-dependently inhibited TRAP activity (10-30 % and the number of multinucleated Oc (55 %. Similar results were observed for low doses of Alendronate (10-8M-10-6M. The co-incubation of low doses of Alendronate with 100 mg/ml of AGEs, did not induce an additional inhibition of TRAP activity or Oc number, to that observed for AGEs alone. High levels of Alendronate (10-5M-10-4M inhibited Oc TRAP activity (20-25 % inhibition versus BSA, and 17 % versus AGEs, and also decreased the number of Oc formed in the presence of AGEs (16 % inhibition versus AGEs. Oc incubated in the presence of 100 µg/ml AGEs, showed a significant increase in the expression of RAGE (152 % versus BSA. Similar results were found after incubating with 10-8M Alendronate (130 % versus BSA. On the contrary, high doses of Alendronate (10-5M did not affect the expression of RAGE in co-cultures incubated with BSA (95 % versus BSA. On the other hand, low doses of Alendronate in the presence of AGEs, did not affect the up-regulation of RAGE induced by AGEs (145 % versus BSA. However, when the Oc were co-incubated with AGEs and 10-5M Alendronate, this dose of BP was able to block the stimulation of RAGE expression induced by AGEs (105

    Multiple sclerosis (MS) affects approximately 400,000 people in the United States and 2.1 million people worldwide. It is the most common chronic, non-traumatic neurological disorder afflicting young people during their peak productive ages. MS can diminish quality of life (QOL) by interfering with the ability to work, pursue leisure activities, and carry on usual life roles. Symptoms that affect QOL may include impaired mobility, fatigue, depression, pain, spasticity, cognitive impairment, sexual dysfunction, bowel and bladder dysfunction, vision and hearing problems, seizures, and sDwallowing and breathing difficulties. Direct medical costs of MS in the United States are estimated in excess of $10 billion per year. Indirect costs of MS include costs of reduced employment or unemployment, assistive equipment, disability related home modifications, and paid and unpaid personal care. Although direct medical costs predominate in the earlier stages of MS, indirect costs of productivity loss are responsible for higher costs later. Disease-modifying therapies (DMTs) lessen symptoms, reduce relapses, and delay disability progression. Unfortunately, many DMTs might produce only modest improvements in QOL. Although symptom-specific therapies do not delay disease progression, they may delay unemployment and dependency, thereby reducing indirect costs. PMID:21761952

These lesions manifest on sun-damaged skin and have the potential to progress to squamous cell carcinoma. Field-directed therapy alone and in combination with lesion-directed treatment is effective in clearing both visible and nonvisible AK lesions. Topical treatments of AKs thus have the potential to improve a patient's well-being. However, evidence demonstrating improvements in patient QoL is limited, and is mostly based on observational or retrospective studies. Some prospective studies have reported unchanged or even worsening QoL despite excellent treatment outcomes. Our prospective, pilot study demonstrated a significant increase in QoL in 28 subjects with AKs of the face treated with ingenol mebutate gel 0.015%. QoL was assessed at days 0 and 60 using the Skindex-16 survey. Mean overall scores improved from 24.5% at baseline to 15.5% at day 60 (P=0.031. Improvements in QoL were consistent with an 80% reduction in AK lesion number at day 60. These improved QoL findings are in line with those from a recent retrospective study using ingenol mebutate 0.015% gel. This study therefore further demonstrates the potential for field therapy to improve both treatment outcomes and patient satisfaction.

    Men receiving androgen deprivation therapy (ADT) for prostate cancer (PCa) are likely to develop metabolic conditions such as diabetes, cardiovascular disease, abdominal obesity and osteoporosis. Other treatment-related side effects adversely influence quality of life (QoL) including vasomotor distress, depression, anxiety, mood swings, poor sleep quality and compromised sexual function. The objective of this study was to systematically review the nature and effects of dietary and exercise interventions on QoL, androgen deprivation symptoms and metabolic risk factors in men with PCa undergoing ADT. An electronic search of CINAHL, CENTRAL, Medline, PsychINFO and reference lists was performed to identify peer-reviewed articles published between January 2004 and December 2014 in English. Eligible study designs included randomised controlled trials (RCTs) with pre- and post-intervention data. Data extraction and assessment of methodological quality with the Cochrane approach was conducted by two independent reviewers. Seven exercise studies were identified. Exercise significantly improved QoL, but showed no effect on metabolic risk factors (weight, waist circumference, lean or fat mass, blood pressure and lipid profile). Two dietary studies were identified, both of which tested soy supplements. Soy supplementation did not improve any outcomes. No dietary counselling studies were identified. No studies evaluated androgen-deficiency symptoms (libido, erectile function, sleep quality, mood swings, depression, anxiety and bone mineral density). Evidence from RCTs indicates that exercise enhances health- and disease-specific QoL in men with PCa undergoing ADT. Further studies are required to evaluate the effect of exercise and dietary interventions on QoL, androgen deprivation symptoms and metabolic risk factors in this cohort. PMID:26584972

    Quality of life (QoL) for people with epilepsy is considered worse than the condition's clinical and medical prognosis would predict. Quantity and quality of social interaction considerably determine QoL. Research shows that a significant proportion of patients with epilepsy experience difficulties with social functioning that is thought to be related to impaired QoL. The aim of this review article is to provide an evidence base for conceptualising and developing interventions to improve quality of life through social functioning, for adults with epilepsy. Previous and current research is considered initially with regards to why such difficulties arise and established interventions that address social competence and functioning are reviewed and explored from the field of schizophrenia, a condition also associated with similar difficulties in social cognition, cognition and negative symptoms. The paper considers the advantages and disadvantages of these interventions, the outcomes and emerging research in this area. Positive findings are found from interventional studies in schizophrenia such as the enhancing potential and generalisation of training in social cognition, the benefits of an integrated approach to improving social functioning and proposal of 'online' interaction approaches. These findings provide interesting and exciting directions for the ultimate goal towards interventions for the improvement of social functioning and quality of life in patients with epilepsy. This is of particular significance as at present there is currently no such dedicated program for people with epilepsy. PMID:25799896

    Chronic productive cough is a common symptom in patients with bronchiectasis that is associated with a reduction in health-related quality of life (QOL). Bronchopulmonary hygiene physical therapy (BHPT) is widely prescribed for patients with bronchiectasis, although the evidence for its efficacy is limited. We set out to prospectively evaluate the impact of BHPT on health-related QOL in patients with non-cystic fibrosis bronchiectasis. We assessed cough symptoms (0-100mm visual analogue scale; VAS) and cough-related QOL in 53 patients with stable non-cystic fibrosis bronchiectasis at baseline and >4 weeks after outpatient-based BHPT. Cough specific health status was assessed with the Leicester Cough Questionnaire (LCQ; total score range 3-21, higher scores representing better QOL). All patients with bronchiectasis complained of cough as the major symptom and had mean (SEM) FEV(1) of 2.1 (0.1)L. Cough-related health status was reduced at baseline; mean (SEM) LCQ score 14.3 (0.6). There were significant improvements in cough symptoms (mean cough VAS before 43.3 (3.6) vs after 27.5 (3.1); mean difference 15.8; 95% CI of difference 9.6-22; p<0.0001) and cough-related health status after BHPT (mean LCQ total score before 14.2 vs after 17.3; mean difference 3.1; 95% confidence interval of difference 2.4-3.9; p<0.001). A significant improvement was seen in all LCQ health-related domains (physical, psychological and social; all p<0.001). Our findings suggest that bronchopulmonary hygiene physical therapy can lead to a significant improvement in cough-related quality of life. PMID:18585027

    Full Text Available Los glucocorticoides son usados comúnmente para el tratamiento de enfermedades inflamatorias, autoinmunes, enfermedades malignas, y en la prevención de rechazo de órganos trasplantados. Un efecto secundario frecuente del tratamiento prolongado es la pérdida de masa ósea que se produce por varios mecanismos y es causa de osteoporosis y fracturas vertebrales. El tratamiento con disfosfonatos ha sido propuesto para esta situación. Presentamos un caso clínico de osteoporosis grave en una niña con dermatomiositis juvenil, que respondió favorablemente al tratamiento con disfosfonatos orales.Glucocorticoids are used for the treatment of inflammatory and autoimmune diseases, cancer, and in prevention of organ rejects. A frequent secondary effect of longterm treatment with corticoids is the loss of bone mass, caused by several mechanisms: decrease in the intestinal calcium absorption, increase of the renal calcium excretion at the distal renal tubule, suppressive effect on the osteoblast and also in apoptosis of osteoclasts, inhibition in local production of IGF I (Insulin-like growth factor and IGFBPs (binding IGF I proteins necessary for bone metabolism, and decrease on osteocalcin production. Longterm treatment with corticoids is associated with osteoporosis and vertebral fractures. To improve this condition, treatment with bisphosphonates has been proposed. We present here a clinical case of a girl with dermatomyositis and severe osteoporosis with vertebral crushes, who responded well to oral bisphophonate treatment.

    The advent of effective immune treatment has meant that myasthenia gravis (MG) is most often not lethal. However, many MG patients still find it difficult to maintain daily activities due to chronic residual fatigability and long-term side effects of medication, since full remission without immune treatment is not common. Our analysis demonstrated that disease severity, dose of oral corticosteroids, and depressive state are the major independent factors negatively associated with self-reported QOL (MG-QOL15-J score). It is noteworthy that oral corticosteroid, the first-line agent for MG, is negatively associated with patients' QOL. When the analysis took into account MGFA postintervention status and dose of oral prednisolne (PSL), the MG-QOL15-J score of MM status patients taking ≤ 5 mg PSL per day is identically low (i.e., just as good QOL) as that seen in CSR and is a target of treatment. In order to veer away from high-dose oral corticosteroids and to achieve early MM or better status with PSL ≤ 5 mg/day, we advocate the early aggressive treatment strategy that can achieve early improvement by performing an aggressive therapy using combined treatment with plasmapheresis and high-dose intravenous methylprednisolone and then maintain an improved clinical status using low-dose oral corticosteroids and calcineurin inhibitors (cyclosporine microemulsion and tacrolimus). The early stages of MG are susceptible to treatment with calcineurin inhibitors. When using cyclosporine microemulsion for MG, blood concentrations 2 h after administration (C2) correlate with clinical improvement and immediately before administration (C0) with side effects (increased serum creatinine and/or hypertension). Monitoring of C2 and C0 levels is useful to estimate efficacy and safety of the drug. PMID:23196511

  10. Can a management pathway for chronic cough in children improve clinical outcomes: protocol for a multicentre evaluation

    Science.gov (United States)

    2010-01-01

    Background Chronic cough is common and is associated with significant economic and human costs. While cough can be a problematic symptom without serious consequences, it could also reflect a serious underlying illness. Evidence shows that the management of chronic cough in children needs to be improved. Our study tests the hypothesis that the management of chronic cough in children with an evidence-based management pathway is feasible and reliable, and improves clinical outcomes. Methods/Design We are conducting a multicentre randomised controlled trial based in respiratory clinics in 5 major Australian cities. Children (n = 250) fulfilling inclusion criteria (new patients with chronic cough) are randomised (allocation concealed) to the standardised clinical management pathway (specialist starts clinical pathway within 2 weeks) or usual care (existing care until review by specialist at 6 weeks). Cough diary, cough-specific quality of life (QOL) and generic QOL are collected at baseline and at 6, 10, 14, 26, and 52 weeks. Children are followed-up for 6 months after diagnosis and cough resolution (with at least monthly contact from study nurses). A random sample from each site will be independently examined to determine adherence to the pathway. Primary outcomes are group differences in QOL and proportion of children that are cough free at week 6. Discussion The clinical management pathway is based on data from Cochrane Reviews combined with collective clinical experience (250 doctor years). This study will provide additional evidence on the optimal management of chronic cough in children. Trial registration ACTRN12607000526471 PMID:21054884

Results: Repeated measures analysis of variance (ANOVA revealed a significant time effect in the general health, vitality, social functioning, and mental health domains of the Short Form 36. It also indicated significant treatment effects on the bodily pain, social functioning, role-emotional, and mental health domains, with higher scores in the TBTR group. One-way analysis of covariance (ANCOVA, using pretreatment values as covariates, showed that TBTR was associated with significantly better QoL post-treatment (bodily pain, social functioning and role-emotional and at follow-up (role-emotional. A significant treatment effect on the role-emotional domain at 12-month follow-up denoted a sustained effect of TBTR relative to CCT. Conclusion: This study provided preliminary evidence that TBTR is at least as effective as CCT in improving several domains of QoL in SAD, specifically when the standard 7-column DTR and the PDL are used.

    Full Text Available PURPOSE: To investigate the effects of bisphosphosnate alendronate (ALD and metotrexate (MTX on an experimental model of Walker 256 carcinosarcoma developed in the oral cavity of rats. METHODS Walker 256 carcinosarcoma cell suspension (0,1 mL containing 10(6 cell/mL was implanted in the alveoli of the first and second molars. The animals were divided and treated with saline, MTX, ALD, and MTX plus ALD. Later, the animals were sacrificed, the tumors were measured and the mandibles were removed for radiographic and histological analysis. RESULTS: In the control group, the radiographic images demonstrated radioluscency with poorly defined borders, and the microscopic examination revealed tumor infiltration into the peripheral and central regions of the bone. Areas of necrosis were commonly seen. In the treated groups with ALD, associated or not with MTX, the radiographic analysis revealed circumscribed tumor-induced osteolysis and various degrees of radiotransparence; while, histologically, preserved bone trabeculae with osteoid formation was observed among malignant cells. CONCLUSION: The bisphosphonate alendronate exherted an osteoprotective effect and induced bone neoformation on the Walker 256 carcinosarcoma inoculated in rat mandibles. The combination of metotrexate with bisphosphonate alendronate is more successful than treatment with the agents alone in controlling the growth of neoplastic cells and in stimulating reactive new bone. Therefore, this may be an alternative treatment to malignant lesions of maxillaries with osteolysis.OBJETIVO: Avaliar o efeito do bisfosfonato alendronato (ALD e do metotrexato (MTX em modelo do carcinossarcoma 256 de Walker na mandíbula de ratos.

    Objective To observe comparatively the efficacies between alendronate and active vitamin D3 in controlling glucocorticoid induced osteoporosis (GIOP) in premenopausal patients with systemic lupus erythematosus (SLE) and without a history of fragility fracture. Methods 91 premenopausal female SLE patients with low-dose glucocorticoids (GCs) therapy or high-dose GCs therapy were divided into 2 groups, including 47 patients who were collected from the outpatient department and received low-dose GCs and 44 patients who were collected from the inpatient department and received high-dose GCs. The patients with either therapy were randomly divided into 3 groups: the calcium group, calcium plus active vitamin D3 group and calcium plus alendronate group. Bone metabolism serological markers and bone mineral density (BMD) values were tested in the first 0, 3 and 6 months. The incidence of fractures and femoral head necrosis was recorded during the treatment process. Results (1) In all groups with low-dose GCs therapy, there was no significant difference in the serum levels of calcium (Ca), inorganic phosphate (PO4) and alkaline phosphatase (ALP) before and after treatment. The serum levels of N-MID osteocalcin (N-MID) and β collagen decomposition segment (β-CT) significantly decreased after the treatment in the calcium plus alendronate group (P0.05). In the calcium plus alendronate group, the BMD values significantly increased after the treatment (P0.05). (3) There was no fracture and femoral head necrosis in all groups with low-dose GCs therapy. In all groups with high-dose GCs therapy, femoral head necrosis occurred in the calcium group and calcium plus active vitamin D3 group, and meanwhile, there was no femoral head necrosis in the calcium plus alendronate group. Conclusions When premenopausal female SLE patients receive low-dose or high-dose GCs therapy respectively, alendronate can better decrease bone turnover, increase BMD and reduce the incidence of femoral head

    This study assessed impact of community based self care integrative treatment provided through mass camps in villages of three districts of Kerala, India endemic for lymphatic filariasis (LF). Two most endemic Primary Health centres (PHCs) were selected from each of the three districts, where maximum concentration of LF patients is recorded. Fourteen one day LF camps, each attended by 30-40 patients were conducted. Trained Accredited Social Health Activists encouraged LF patients to attend camps. Skin wash and drying, care of bacterial entry points using dermatology drugs, and simple yoga and breathing exercises were demonstrated in these camps. Patients were advised to continue these self care activities daily at home for six months. The quality of life (QoL) of LF patients was determined for Indian life style domains using validated and pretested specific questionnaire (LF-specific QoL questionnaire-LFSQQ). It addressed conditions and state of individuals with reference to LF. The questionnaire had 7 domains and each domain consisted of a series of questions with likert scale (no problem, mild, moderate, severe, most severe). 446 patients attended one day camps to get training on integrative self care treatment. 425 patients (95.3%) were followed up after six months and QoL was reassessed. Each patient's QoL in mobility, self care, usual activity, pain and discomfort and social relationship significantly improved (P value change. The disease burden, for the purpose of the study was measured by asking questions about history of painful redness, swelling and cellulitis of legs (filarial fever), foul smell (odor), itching (eczema/discharge from limb), wound (non healing ulcer) and weight/size of the limb. The difference in disease burden as recorded during the sixth month follow up was measured using dependent t test, reduced significantly (P value <0.01) in 409 (96.2%) patients. 103 (24.2%) patients experienced fever during follow up.

    Full Text Available Objectives: Cognitive impairment is a common problem among the elderly and is believed to be a precursor to dementia. This study aimed to explore the effectiveness of a combined dance and relaxation intervention as compared to relaxation alone in reducing anxiety and depression levels and improving quality of life (QOL and cognitive function among the cognitively impaired elderly. Methods: This quasi-experimental study was conducted between May and December 2013 in Peninsular Malaysia. Subjects from four government residential homes for older adults aged ≥60 years with mild to moderate cognitive function as assessed by the Mini-Mental State Examination were included in the study. Subjects were divided into an intervention group and a control group; the former participated in a combined poco-poco dance and relaxation intervention whilst the latter participated in relaxation exercises only. Both groups participated in two sessions per week for six weeks. Anxiety and depression were self-assessed using the Hospital Anxiety and Depression Scale and QOL was self-assessed using the Quality of Life in Alzheimer’s Disease questionnaire. Results: A total of 84 elderly subjects were included in the study; 44 were in the intervention group and 40 were in the control group. When compared to control subjects, those in the intervention group showed significantly decreased anxiety (P <0.001 and depression (P <0.001 levels as well as improved QOL (P <0.001 and cognitive impairment (P <0.001. Conclusion: Dance as a form of participationbased physical exercise was found to reduce anxiety and depression levels and improve QOL and cognitive function among the studied sample of cognitively impaired elderly subjects in Malaysia.

    Full Text Available Abstract Background Beside traditional outcomes of safety and (cost-effectiveness, the Institute of Medicine states patient-centeredness as an independent outcome indicator to evaluate the quality of healthcare. Providing patient-centered care is important because patients want to be heard for their ideas and concerns. Healthcare areas associated with high emotions and intensive treatment periods could especially benefit from patient-centered care. How care can become optimally improved in patient-centeredness is unknown. Therefore, we will conduct a study in the context of Dutch fertility care to determine the effects of a multifaceted approach on patient-centeredness, patients’ quality of life (QoL and levels of distress. Our aims are to investigate the effectiveness of a multifaceted approach and to identify determinants of a change in the level of patient-centeredness, patients’ QoL and distress levels. This paper presents the study protocol. Methods/Design In a cluster-randomized trial in 32 Dutch fertility clinics the effects of a multifaceted approach will be determined on the level of patient-centeredness (Patient-centredness Questionnaire – Infertility, patients’ QoL (FertiQoL and levels of distress (SCREENIVF. The multifaceted approach includes audit and feedback, educational outreach visits and patient-mediated interventions. Potential determinants of a change in patient-centeredness, patients’ QoL and levels of distress will be collected by an addendum to the patients’ questionnaire and a professionals’ questionnaire. The latter includes the Organizational Culture Assessment Instrument about the clinic’s culture as a possible determinant of an increase in patient-centered care. Discussion The study is expected to yield important new evidence about the effects of a multifaceted approach on levels of patient-centeredness, patients’ QoL and distress in fertility care. Furthermore, determinants associated with a change

  18. A mixed exercise training programme is feasible and safe and may improve quality of life and muscle strength in multiple myeloma survivors

    International Nuclear Information System (INIS)

    Exercise programmes are beneficial for cancer patients however evidence is limited in patients with multiple myeloma (MM), a cancer that is characterised by osteolytic bone disease, giving rise to high levels of bone morbidity including fractures and bone pain. We conducted a single arm phase 2 study of an exercise programme (EP) as rehabilitation for treated MM patients, to evaluate feasibility, effects on QOL and physiological parameters. Patients were given individualised programmes, comprising stretching, aerobic and resistance exercises, carried out under supervision for 3 months then at home for a further 3 months. Study uptake was high, 60 of 75 (80%) patients approached consented to the study. Screen failures (11, due to fracture risk and disease relapse) and patient withdrawals (12) resulted in a final 37 patients enrolling on the programme. These 37 patients demonstrated high attendance rates in the supervised classes (87%), and high levels of adherence in home exercising (73%). Patients reported better QOL following the EP, with improvement in FACT-G and Fatigue scores over time from baseline (p<0.01 for both, one-way repeated measures ANOVA) to 6 months. Upper and lower limb strength also improved on the EP, from baseline to 6 months (p<0.01 for both). There were no adverse reactions. An EP in MM patients is feasible and safe, with high attendance and adherence. Benefits in QOL, fatigue and muscle strength await confirmation in randomized studies, prompting urgent evaluation of the benefits of EP in the rehabilitation of MM patients

  20. Improvement of cancer cachexia with chemothermotherapy in a patient with advanced pancreatic cancer

    International Nuclear Information System (INIS)

    The ultimate goal of cancer treatment is to achieve a complete eradication of the cancer. However, patients with terminal cancer are also treated to obtain an improvement in their quality of life (QOL). In this report, we describe the dramatic response of an end-stage pancreatic cancer patient with cachexia to a combination of hyperthermia (HT) and chemotherapy (CH). The patient was treated with a combination of intermittent 5-fluorouracil (5-FU)/cisplatin (CDDP) therapy and HT. Three months later, the local recurrent cancer had disappeared, the liver metastases were reduced by 80%, the lung metastatic lesion was markedly reduced, tumor markers had returned to normal, and the cachexia had been almost reversed. Performance status (PS) improved from 4 to 1, QOL improved, and the patient survived until his 258th hospital day. In this patient, the combination of CH and HT was useful not only for improvement of cachexia, but also for tumor reduction. A possible mechanism leading to this effect is discussed. (author)

    Full Text Available Abstract Background Successful highly active antiretroviral therapy (HAART regimens have resulted in substantial improvements in the systemic health of HIV infected persons and increased survival times. Despite increased systemic health, the prevalence of minor HIV-associated cognitive impairment appears to be rising with increased longevity, and it remains to be seen what functional outcomes will result from these improvements. Cognitive impairment can dramatically impact functional ability and day-to-day productivity. We assessed the relationship of quality of life (QOL and neuropsychological functioning with successful HAART treatment. Methods In a prospective longitudinal study, subjects were evaluated before instituting HAART (naïve or before changing HAART regimens because current therapy failed to maintain suppression of plasma viral load (treatment failure. Subjects underwent detailed neuropsychological and neurological examinations, as well as psychological evaluation sensitive to possible confounds. Re-evaluation was performed six months after institution of the new HAART regimen and/or if plasma viral load indicated treatment failure. At each evaluation, subjects underwent ultrasensitive HIV RNA quantitative evaluation in both plasma and cerebrospinal fluid. Results HAART successes performed better than failures on measures exploring speed of mental processing (p Conclusion Our study investigated the relationship between HIV-associated neurocognitive impairment and quality of life. HAART failures experienced slower psychomotor processing, and had increased self-reports of physical health complaints and substance abuse. Contrariwise, HAART successes experienced improved mental processing, demonstrating the impact of successful treatment on functioning. With increasing life expectancy for those who are HIV seropositive, it is important to measure cognitive functioning in relation to the actual QOL these individuals report. The study

    An investigation of the effect of facial lipofilling on patient's satisfaction is a challenging and ongoing research area. Therefore, the aim of this study was to investigate the impact of aesthetic intervention on self-perceived improvement in facial appearance and quality of life (QoL) after 1- and 6-month follow-ups. In the period from October 1, 2014, to March 1, 2015, a total of 63 consecutive subjects who underwent a facial lipofilling were included in the study. The satisfaction with facial appearance was estimated by using the Satisfaction with Facial Appearance Overall scale. QoL was assessed by using the 36-Item Short Form Health Survey (SF-36). Severity of depressive and anxiety symptoms was quantified by using the Hamilton depression and anxiety rating scales. The self-esteem was assessed by Rosenberg self-esteem scale. The average Satisfaction with Facial Appearance Overall scale score at baseline was 45.5 ± 13.0, while this score reached values of 84.5 ± 16.2 after 1 month (Z = -6.744, p Appearance Overall scale score from baseline to 1-month follow-up was 38.9 ± 21.2 and from baseline to 6-month follow-up was 37.1 ± 18.9. Statistically significant improvement in QoL at each subsequent time point, compared with those at baseline, was detected for all domains of the SF-36 except for subscales of physical functioning and pain. It has been highlighted that advanced social life was strongly associated with improvement in satisfaction with facial appearance, better self-esteem, and lower level of anxiety and depression during the period of follow-up after facial lipofilling. The results of this study supported the hypothesis that the level of self-confidence and mental health-related QoL could be significantly improved following facial lipofilling treatment.

  12. Improving treatment satisfaction and other patient-reported outcomes in people with type 2 diabetes: the role of once-daily insulin glargine.

    Insulin therapy becomes essential for many people with type 2 diabetes. After starting insulin, people with diabetes that is poorly controlled with oral agents typically report improved well-being and treatment satisfaction. However, healthcare professionals and people with type 2 diabetes are often reluctant to begin insulin treatment, citing concerns such as time/resources needed to educate patients, increased risks of hypoglycaemia and fear of injections, which lead them to focus on intensifying conventional oral therapy. Insulin glargine, which offers people with diabetes a once-a-day injection regimen with low risk of hypoglycaemia, is more likely to overcome such initial barriers than other more complex insulin regimens. Once-daily insulin glargine, in combination with modern glucose-dependent oral agents that do not need to be chased with food to prevent hypoglycaemia, does not require the fixed mealtimes and set amounts of carbohydrates necessary with twice-daily injection mixes and older sulphonylureas. We know that it is such dietary restrictions that cause the most damage to quality of life (QoL). To avoid damaging QoL unnecessarily and to ensure optimal satisfaction with treatment, it is important to evaluate the effects of treatment on QoL, treatment satisfaction and other patient-reported outcomes (PROs) using questionnaires validated for this purpose, such as the widely used Diabetes Treatment Satisfaction Questionnaire and the Audit of Diabetes-Dependent Quality of Life measure. A systematic electronic literature search identified reports of studies evaluating PROs associated with insulin glargine in comparison with other treatments. The studies show that insulin glargine is usually associated with greater improvements in treatment satisfaction and other PROs compared with intensifying oral therapy or alternative insulin regimens.

    Full Text Available BACKGROUND: The Dementia In Residential care: EduCation intervention Trial (DIRECT was conducted to determine if delivery of education designed to meet the perceived need of GPs and care staff improves the quality of life of participants with dementia living in residential care. METHODOLOGY/PRINCIPAL FINDINGS: This cluster-randomised controlled trial was conducted in 39 residential aged care facilities in the metropolitan area of Perth, Western Australia. 351 care facility residents aged 65 years and older with Mini-Mental State Examination ≤ 24, their GPs and facility staff participated. Flexible education designed to meet the perceived needs of learners was delivered to GPs and care facility staff in intervention groups. The primary outcome of the study was self-rated quality of life of participants with dementia, measured using the QOL-Alzheimer's Disease Scale (QOL-AD at 4 weeks and 6 months after the conclusion of the intervention. Analysis accounted for the effect of clustering by using multi-level regression analysis. Education of GPs or care facility staff did not affect the primary outcome at either 4 weeks or 6 months. In a post hoc analysis excluding facilities in which fewer than 50% of staff attended an education session, self-rated QOL-AD scores were 6.14 points (adjusted 95%CI 1.14, 11.15 higher at four-week follow-up among residents in facilities randomly assigned to the education intervention. CONCLUSION: The education intervention directed at care facilities or GPs did not improve the quality of life ratings of participants with dementia as a group. This may be explained by the poor adherence to the intervention programme, as participants with dementia living in facilities where staff participated at least minimally seemed to benefit.

  17. CANDU improvement

    International Nuclear Information System (INIS)

    The evolution of the CANDU family of nuclear power plants is based on a continuous product development approach. Proven equipment and system concepts from operating stations are standardized and used in new products. Due to the modular nature of the CANDU reactor concept, product features developed for CANDU 9 can easily be incorporated in other CANDU products such as CANDU 6. Design concepts are being developed for advanced CANDU 6 or larger advanced CANDU, depending on the number of fuel channels and the fuel cycle selected. This paper provides a description of the design improvements being incorporated in CANDU 9 and further design enhancements being studied for future incorporation in CANDU 6 or larger advanced CANDU meeting the requirements of future CANDU owners. The design enhancement objectives are: To improve operational simplicity by applying modern information technology; to improve safety in a cost effective way; to improve system and component reliability and to increase plant life; to improve economics and to reduce owners' risks during all phases of a project using up-front licensing, an improved engineering process and project tools during design, construction and operation; to continue to exploit the neutron economy of CANDU with the development of advanced fuels and fuel cycles.

    Full Text Available A previously unknown side effect of biphosphonate use is emerging. In a specific patient group on long term biphosphonate therapy stress femur fractures seem to occur. The typical presentation consists of prodromal pain in the affected leg and/or a discrete cortical thickening on the lateral side of the femur in conventional radiological examination or the presentation with a spontaneous transverse subtrochanteric femur with typical features. We present three cases of this stress fracture in patients on bisphosphonate therapy. One of these patients suffered a bilateral femur fracture of the same type. In our opinion, in patients on bisphosphonate therapy who present with a spontaneous femur fracture, seizing therapy is advisable. In bilateral cases preventive nailing should be considered.

    Full Text Available Background. Diabetic patients with chronic kidney disease (CKD suffer from low quality of life (QOL. We aim to assess the effectiveness of auricular acupressure for QOL improvement in these patients. Materials and Methods. Sixty-two participants were randomly assigned to an auricular or a control arm in a randomized controlled trial. Participants in the auricular arm were instructed to perform auricular acupressure 3–5 times per day for 3 months, when they were receiving conventional treatments. Participants in the control arm received conventional treatments only. The primary outcome was the summarized score of Kidney Disease and Quality of Life Short-Form (KDQOL-SF at 3 months after randomization. The secondary outcomes included the 36-Item Short Form Health Survey (SF-36, glycosylated hemoglobin (HbA1c, and estimated glomerular filtration rate (eGFR. Results. The summarized KDQOL differed significantly between the acupressure (76.6, 95% CI, 72.2 to 81.0 and the control group (61.8, 95% CI, 57.7 to 65.9. Similar results were found in the SF-36 scores. HbA1c and eGFR were not found to be significantly different between the arms and neither were the adverse events. Conclusion. Auricular acupressure was well tolerated in diabetic patients with chronic kidney diseases receiving hemodialysis. Future research is needed to confirm these results.

  3. Concomitant treatment of brain metastasis with Whole Brain Radiotherapy [WBRT] and Temozolomide [TMZ] is active and improves Quality of Life

    International Nuclear Information System (INIS)

    Brain metastases (BM) represent one of the most frequent complications related to cancer, and their treatment continues to evolve. We have evaluated the activity, toxicity and the impact on Quality of Life (QoL) of a concomitant treatment with whole brain radiotherapy (WBRT) and Temozolomide (TMZ) in patients with brain metastases from solid tumors in a prospective Simon two stage study. Fifty-nine patients were enrolled and received 30 Gy WBRT with concomitant TMZ (75 mg/m2/day) for ten days, and subsequently TMZ (150 mg/m2/day) for up to six cycles. The primary end points were clinical symptoms and radiologic response. Five patients had a complete response, 21 patients had a partial response, while 18 patients had stable disease. The overall response rate (45%) exceeded the target activity per study design. The median time to progression was 9 months. Median overall survival was 13 months. The most frequent toxicities included grade 3 neutropenia (15%) and anemia (13%), and only one patient developed a grade 4 thrombocytopenia. Age, Karnofsky performance status, presence of extracranial metastases and the recursive partitioning analysis (RPA) were found to be predictive factors for response in patients. Overall survival (OS) and progression-free survival (PFS) were dependent on age and on the RPA class. We conclude that this treatment is well tolerated, with an encouraging objective response rate, and a significant improvement in quality of life (p < 0.0001) demonstrated by FACT-G analysis. All patients answered the questionnaires and described themselves as 'independent' and able to act on their own initiatives. Our study found a high level of satisfaction for QoL, this provides useful information to share with patients in discussions regarding chemotherapy treatment of these lesions

METHODS Eighty four patients with Chronic Kidney Disease (CKD were enrolled in the study. Quality of life (QoL was measured by means of Short Form-36 (SF-36 and subscale scores were calculated prior to the education and counseling . The education and counseling program focuses on behaviour style including excersize and diet issues and also cessation of smoking and alcohol consumption. These programs has been conducted by a nurse twice a week, throughout eight weeks. After this program, the patients have been evaluated by means of SF-36 and a questionary for CKD patients. Data were analysed by SPSS pocket program. RESULTS All dimensions of QoL of patients were signicicantly better after the education and counseling, as compared with that of prior to the intervention. The mean of exercize duration and percent of patients who adjusted diet programme were increased and serum albumin means were increased, serum urea and serum creatinine means were decreased after the education and counseling compared with that of prior to the education and counseling. Systolic tension arteriel means were lower after the education and counseling compared with that of prior to the education and counseling. However, the number of cigarette in a day, the glass of alcohol in a week and the diastolic tension arteriel means were not different after the education and counseling compared with that of prior to the intervention. CONCLUSION The patients with chronic kidney disease positevely improved their health-related quality of life and some renal functions after the education and counseling.

    Full Text Available Abstract Background Frequent rehospitalisations and poorer survival chances in heart failure (HF patients may partly be explained by poor medication adherence. There are multiple medication-related reasons for suboptimal adherence, but psychological reasons may also be important. A novel TELEmonitoring device may improve MEDication adherence in HF patients (TELEMED-HF. TELEMED-HF is a randomized, controlled clinical intervention trial designed to examine (1 the efficacy and cost-efficiency of an electronic medication adherence support system in improving and monitoring HF patients' medication adherence; (2 the effect of medication adherence on hospitalizations and health care consumption; as well as on (3 clinical characteristics, and Quality of Life (QoL; and (4 clinical, sociodemographic, and psychological determinants of medication adherence. Methods/Design Consecutive patients with chronic, systolic HF presenting to the outpatient clinic of the TweeSteden Hospital, The Netherlands, will be approached for study participation and randomly assigned (1:1 following blocked randomization procedures to the intervention (n = 200 or usual care arm (n = 200. Patients in the intervention arm use the medication support device for six months in addition to usual care. Post-intervention, patients return to usual care only and all patients participate in four follow-up occasions over 12 months. Primary endpoints comprise objective and subjective medication adherence, healthcare consumption, number of hospitalizations, and cost-effectiveness. Secondary endpoints include disease severity, physical functioning, and QoL. Discussion The TELEMED-HF study will provide us a comprehensive understanding of medication adherence in HF patients, and will show whether telemonitoring is effective and cost-efficient in improving adherence and preventing hospitalization in HF patients.

    Abstract Background/Introduction: Aidi injection plus radiotherapy is widely used for lung cancer in China. Can Aidi injection alleviate the toxicity and improve the clinical efficacy of radiotherapy in lung cancer? Has Aidi injection the attenuation and synergistic efficacy to radiotherapy? There is lack of strong evidence to prove it. Objectives: To reveal its real attenuation and synergistic efficacy to radiotherapy and provide sufficient evidence for adjuvant chemotherapy strategies to lung cancer, we systematically evaluated all related studies. Data Sources: We collected all studies about Aidi injection plus radiotherapy for lung cancer in Medline, Embase, Web of Science, China national knowledge infrastructure database (CNKI), Chinese scientific journals full-text database (VIP), Wanfang database, China biological medicine database (CBM) (established to June 2015), and Cochrane Central Register of Controlled Trials (June 2015), evaluated their quality according to the Cochrane evaluation handbook of randomized controlled trials (5.1.0), extracted data following the PICO principles and synthesized the data by Meta analysis. Results: Sixteen randomized controlled trials (RCTs) with 1192 lung cancer patients were included, with general methodological quality in most trials. The merged relative risk (RR) values and their 95% CI of meta-analysis for objective response rate (ORR), disease control rate (DCR), and quality of life (QOL) were as follows: 1.54, (1.39,1.70), 1.10 (1.02, 1.19), and 2.13 (1.68, 2.68).

    In elderly men, benign prostatic hyperplasia (BPH) is a major risk factor for sexual dysfunctions (SDys). Additionally, the standard treatments for BPH symptoms, alpha blockers and 5-alpha-reductase inhibitors, cause SDys themselves. Preparations from saw palmetto berries are an efficacious and well-tolerated symptomatic treatment for mild to moderate BPH and have traditionally been used to treat SDys. We conducted an open multicentric clinical pilot trial to investigate whether the saw palmetto berry preparation Prostasan® influenced BPH symptoms and SDys. Eighty-two patients participated in the 8-week trial, taking one capsule of 320 mg saw palmetto extract daily. At the end of the treatment, the International Prostate Symptom Score was reduced from 14.4 ± 4.7 to 6.9 ± 5.2 (p BPH QoL-9 sex total improved from 137.3 ± 47.9 to 195.0 ± 56.3 (p BPH symptoms and reduced SDys. This was the first trial with saw palmetto to show improvement in BPH symptoms and SDys as well. [Corrections made here after initial online publication.] PMID:22522969

    Full Text Available At present, liver transplantation remains the only curative option for the patients with cirrhosis and end-stage liver diseases. The survival rate and recurrent diseases remain the major issues in the patient post-transplantation. Unani medicine is one of the oldest traditional systems of medicine which has been treating chronic liver diseases and cirrhosis (Talayyaful-Kabid for centuries. The current study aimed to assess the impact of Unani treatment on decompensated cirrhosis and collect data to warrant further clinical trials. Authors conducted a case series on five patients with decompensated cirrhosis and portal hypertension. The disease was confirmed through FibroScan and ultrasound and treated with Unani treatment orally for seven months. Results were evaluated based on FibroScan, liver function test (LFT, EuroQol-5D (EQ5D, Child-Pugh and TTO-TIME (trade-off question. Significant improvements in LFT, fibrosis and quality of life were achieved in the studied patients. The literature related to the herbal constituents of chief medicines used to treat in this case was reviewed. The herbs proved their potential anti-oxidative, anti-inflammatory, hepato-protective, immuno-modulator and antiviral activities, suggesting plausible mechanisms of action in the cases. The preliminary findings indicated the potential therapeutic role of Unani treatment in decompensated cirrhosis. Clinical trials should be conducted to explore further therapeutic potential of Unani treatment in decompensated cirrhosis.

    Full Text Available Information technology (IT is pushing ahead with drastic reforms of modern life for improvement of human welfare. Objects constitute “Information Networks” through smart, self-regulated information gathering that also recognizes and controls current information states in Wireless Sensor Networks (WSNs. Information observed from sensor networks in real-time is used to increase quality of life (QoL in various industries and daily life. One of the key challenges of the WSNs is how to achieve lossless data transmission. Although nowadays sensor nodes have enhanced capacities, it is hard to assure lossless and reliable end-to-end data transmission in WSNs due to the unstable wireless links and low hard ware resources to satisfy high quality of service (QoS requirements. We propose a node and path traffic prediction model to predict and minimize the congestion. This solution includes prediction of packet generation due to network congestion from both periodic and event data generation. Simulation using NS-2 and Matlab is used to demonstrate the effectiveness of the proposed solution.

    Full Text Available The purpose of this paper is to verify the association between outcome measures of health-related quality of life (HRQoL and disability, BMI, gender, and age. Adult obese patients were clustered using HRQoL (IWQoL-Lite and disability (WHO-DAS II scores into three groups: mild, moderate, and high. One-way ANOVA with Bonferroni post hoc test was used to evaluate differences in age and BMI between subjects from different clusters, contingency coefficient to test the relationship between cluster groups and gender. In total, 117 patients were enrolled: subjects with higher disability and HRQoL decrement were older and had higher BMI. Women were more likely to present moderate disability and reduction in HRQoL, while men more likely presented mild disability and HRQoL reduction. Our data further confirm the connection between disability and HRQoL, high BMI and older age. These data obtained with outcomes measures might better address rehabilitation programs.

  5. DASH (disabilities of the arm, shoulder, and hand) evaluation of QOL for carpal tunnel syndrome

    International Nuclear Information System (INIS)

    The questionnaire on the disabilities of the arm, shoulder, and hand is a region-specific, self-administered outcome instrument that is developed as a measure of self-rate upper extremity disability and symptoms. Last year, the Japanese version of disabilities of the arm, shoulder and hand (DASH) was cross-culturally adapted. The main purpose of this study is to analyze the relationship between DASH and clinical assessment (findings of MRI and electrodiagnostic parameters). The subjects comprised 41 patients (6 males and 35 females) with carpal tunnel syndrome (CTS), except for cases with other upper extremity disorders. These subjects prospectively completed DASH 1 (disability module), DASH 2 (symptom module), and DASH (disability and symptom module) before the release of the open carpal tunnel. The patients were divided into 3 groups based on the symptom duration (A: shorter than 3 months, B: 4-11 months, C: longer than 12 months). All patients were preoperatively assessed with regard to sensory conduction velocity (SCV) and compound muscle action potential (CMAP). In addition, all patients underwent MRI in order to evaluate the flexor tenosynovial swelling represented by palmar bowing of the flexor retinaculum (PBFR). The relationships were estimated using the Spearman rank score, unpaired t tests, and Bonferroni tests. DASH 2 scores indicated greater responsiveness than DASH 1, which reflected the character of CTS. DASH 1 scores were higher in patients who were affected in their dominant hand than in those whose nondominant hand was affected. The DASH scores decreased significantly in groups A and B, with the exception of C. However, DASH did not show any correlation either with the parameters, age, or MRI assessment. DASH can be used for the research of preoperative outcomes related to CTS. It also has the advantage of being useful in assessing and comparing the outcome for various other hand disorders. (author)

    Full Text Available Abstract Background Improving the quality of health care services requires tailoring facilities to fulfil patients' needs. Satisfying patients' healthcare needs, listening to patients' opinions and building a closer provider-user partnership are central to the NHS. Few published studies have discussed cardiovascular patients' health needs, but they are not comprehensive and fail to explore the contribution of outcome to needs assessment. Method A comprehensive self-administered health needs assessment (HNA questionnaire was developed for concomitant use with generic (Short Form-12 and EuroQOL and specific (Seattle Angina Questionnaire health-related quality of life (HRQL instruments on 242 patients admitted to the Acute Cardiac Unit, Nottingham. Results 38% reported difficulty accessing health facilities, 56% due to transport and 32% required a travelling companion. Mean HRQOL scores were lower in those living alone (P Conclusions Patients wanted more social (suitable accommodation, companionship, social visits and physical (help aids, access to healthcare services, house work support. The construct validity and intra-class reliability of the HNA tool were confirmed. Our results indicate a gap between patients' health needs and available services, highlighting potential areas for improvement in the quality of services.

    Directory of Open Access Journals (Sweden)

    Jeffrey W. Young

    2013-01-01

    Full Text Available Chronic stable angina (CSA is a significant problem in the United States that can negatively impact patient quality of life (QoL. An accurate assessment of the severity of a patient’s angina, the impact on their functional status, and their risk of cardiovascular complications is key to successful treatment of CSA. Active communication between the patient and their healthcare provider is necessary to ensure that patients receive optimal therapy. Healthcare providers should be aware of atypical symptoms of CSA in their patients, as patients may continue to suffer from angina despite the availability of multiple therapies. Patient questionnaires and symptom checklists can help patients communicate proactively with their healthcare providers. This paper discusses the prevalence of CSA, its impact on QoL, and the tools that healthcare providers can use to assess the severity of their patients’ angina and the impact on QoL.

    The analysis and prediction of time series data have been addressed by researchers. Many techniques have been developed to be applied in various areas, such as weather forecasting, financial markets and hydrological phenomena involving data that are contaminated by noise. Therefore, various techniques to improve the method have been introduced to analyze and predict time series data. In respect of the importance of analysis and the accuracy of the prediction result, a study was undertaken to test the effectiveness of the improved nonlinear prediction method for data that contain noise. The improved nonlinear prediction method involves the formation of composite serial data based on the successive differences of the time series. Then, the phase space reconstruction was performed on the composite data (one-dimensional) to reconstruct a number of space dimensions. Finally the local linear approximation method was employed to make a prediction based on the phase space. This improved method was tested with data series Logistics that contain 0%, 5%, 10%, 20% and 30% of noise. The results show that by using the improved method, the predictions were found to be in close agreement with the observed ones. The correlation coefficient was close to one when the improved method was applied on data with up to 10% noise. Thus, an improvement to analyze data with noise without involving any noise reduction method was introduced to predict the time series data.

    The Stratospheric Observatory for Infrared Astronomy (SOFIA) is a joint project between NASA and Deutsches Zentrum fuer Luft- und Raumfahrt (DLR), the German Space Agency. SOFIA is based in a Boeing 747 SP and flown in the stratosphere to observe infrared wavelengths unobservable from the ground. In 2007 Dryden Flight Research Center (DFRC) inherited and began work on improving the plane and its telescope. The improvements continue today with upgrading the plane and improving the telescope. The Observatory Verification and Validation (V&V) process is to ensure that the observatory is where the program says it is. The Telescope Status Display (TSD) will provide any information from the on board network to monitors that will display the requested information. In order to assess risks to the program, one must work through the various threats associate with that risk. Once all the risks are closed the program can work towards improving the observatory.

    International Nuclear Information System (INIS)

    During the last six years since HANARO commenced power operation in 1995, the facility has been improved and enhanced continuously. Every performance of reactor systems is being measured and analyzed to confirm that all the results of the reactor performance meet design values. The utilization facilities in HANARO have been equipped following the installation schedule within the given budget. Recently some improvements have been made in the systems to enhance their functions. The first one is fuel failure detection system (FFDS) using NaI, which was not so sensitive to monitor gamma activity due to the fuel failure and the system was renovated by changing NaI with BF3. The second is pool cover, which is presently used to prevent any materials from being dropped into the reactor pool during the reactor operation. The function of this pool cover has been changed to accommodate some utilization facilities on the cover to provide a convenient working place. The third improvement is the aluminum plugging of the infrequently using vertical irradiation holes in the reflector tank in order to increase the neutron flux of frequently using holes. The aluminum plugging of the holes caused significant neutron increases to the actively utilizing holes. In this paper described are how the system and component are improved and what the present expansion of utilization fields is in HANARO and what kinds of action are taken in order to enhance the utilization of the facility. And then, finally the prospect of the facility was drawn as a conclusion. (orig.)

The aim of this study is to compare the quality of life (QoL in partially edentulous osteoporotic women who have missing teeth restored with dental implant retained restorations with those who do not and, secondarily, to report the rate of osteonecrosis in this sample. Methods. 237 participants completed the Utian QoL survey, a 23-question document measuring across psychosocial domains of well-being including occupational, health, emotional, and sexual domains which together contribute to an overall score. The subset of participants having dental implant supported prosthesis (64 was compared to the subset having nonimplant supported fixed restorations (47, the subset having nonimplant supported removable restorations (60, and the subset having no restoration of missing teeth (66. Results. ANOVA showed significant difference in all QoL domains between the four subsets (p<0.05. Although 134 reported oral bisphosphonate and 51 reported IV bisphosphonate use, no signs of ONJ were identified in any participants. Conclusion. These findings show implant retained oral rehabilitation has a statistically significant impact over nonimplant and traditional fixed restorations, removable restorations, and no restoration of missing teeth in far reaching areas including occupational, health, emotional, sexual, and overall QoL. These findings also support future examination of psychosocial outcomes associated with oral rehabilitation and the incorporation of oral health into women’s health promotion.

    Full Text Available Outcomes of cataract surgery are worse than we would like them to be. Community-based studies show that up to 40% of eyes have a postoperative presenting vision of < 6/60. Eyes with intraocular lenses (IOLs do better; however, it has been shown that even in prosperous middle-income countries, such as Venezuela, in 20% of pseudophakic eyes presenting vision was < 6/60 and in 15% best corrected vision was worse than 6/60.Poor outcomes matter. Patients deserve improved vision whenever possible and poor outcomes deter prospective patients from coming for surgery and probably reduce their willingness to pay for their treatment – particularly if they have to pay in advance!In this article, we offer some suggestions for improving the quality of cataract surgery. We admit that there is little evidence base for most of these suggestions and that some of them are controversial. However, we hope to stimulate debate.

    Rush Prudential Health Plans, a managed care company located in Chicago, Illinois, is implementing a service quality improvement process across the three products it markets in the Chicago area: The Anchor Plan (a primarily staff model HMO), The Affiliates Plan (a network model HMO), and The Plus Plan (a point of service plan). In 1994, the company instituted an annual member satisfaction research study, conducted across the three plans, and began building a link between external customer requirements and internal operations. The research process consisted of three stages: determining external customer requirements, translating these customer-defined "symptoms" into underlying root causes, and developing a service quality improvement action plan. Rush Prudential determined that traditional "report card" surveys would not meet their goals for the information measurement process. A detailed diagnostic telephone survey was used to provide a picture of the entire clinical encounter, from scheduling an appointment through the time a member left the physician's office.

    During the recent LHC shutdown period, ATLAS performed vital maintenance and improvements on the various sub-detectors. For the calorimeters, repairs were carried out on front-end electronics and power supplies to recover detector coverage that had been lost since the last maintenance period. The ALFA luminosity detector was installed along the beam line and is currently being commissioned. Smaller scale repairs were needed on the Inner Detector. Maintenance on the muon system included repairs on the readout as well as updates and leak checks in the gas systems. Six TGC chambers were also replaced. This poster summarizes the repairs and their expected improvement for physics performance and reliability of ATLAS for the upcoming LHC run.

  10. Improving PPM Using Dictionaries

    Hu, Yichuan; Zhang,; Khan, Farooq; Li, Ying

    2010-01-01

    We propose a method to improve traditional character-based PPM text compression algorithms. Consider a text file as a sequence of alternating words and non-words, the basic idea of our algorithm is to encode non-words and prefixes of words using character-based context models and encode suffixes of words using dictionary models. By using dictionary models, the algorithm can encode multiple characters as a whole, and thus enhance the compression efficiency. The advantages of the proposed algorithm are: 1) it does not require any text preprocessing; 2) it does not need any explicit codeword to identify switch between context and dictionary models; 3) it can be applied to any character-based PPM algorithms without incurring much additional computational cost. Test results show that significant improvements can be obtained over character-based PPM, especially in low order cases.

  11. Strategies for Improving Justification

    International Nuclear Information System (INIS)

    Good practice in radiology relies on a core principle that each examination is justified for the patient involved. An international workshop organized by the IAEA and the European Commission concluded that: “There is a significant and systemic practice of inappropriate examination in radiology.” Audit reveals that 20–50% of examinations are routinely not justified and the figure can be as high as 60–77% in particular cases (e.g. for lumbar spine examinations or cardiac angiography). Doctors/health professionals generally have poor awareness of the risks involved and consistently underestimate them. Knowledge of, and compliance with, guidelines for referral for common examinations is poor. The ethical background considerations to this situation are briefly reviewed and a strategy for improvement is proposed, i.e. the global ‘three As’ campaign of improving awareness, appropriateness and audit adopted by the IAEA.

    Utilizing the comment section of patient satisfaction surveys, Clark Memorial Hospital in Jeffersonville, IN went through a thoughtful process to arrive at an experience that patients said they wanted. Two Lean Six Sigma tools were used--the Voice of the Customer (VoC) and the Affinity Diagram. Even when using these tools, a facility will not be able to accomplish everything the patient may want. Guidelines were set and rules were established for the Process Improvement Team in order to lessen frustration, increase focus, and ultimately be successful. The project's success is driven by the team members carrying its message back to their areas. It's about ensuring that everyone is striving to improve the patients' experience by listening to what they say is being done right and what they say can be done better. And then acting on it.

    The CANDU 9 is a family of single-unit Nuclear Power Plant designs based on proven CANDU concepts and equipment from operating CANDU plants capable of generating 900 MWe to 1300 MWe depending on the number of fuel channel used and the type of fuel, either natural uranium fuel or slightly enriched uranium fuel. The basic design, the CANDU 9 480/NU, uses the 480 fuel channel Darlington reactor and employs Natural Uranium (NU) fuel Darlington, the latest of the 900 MWe Class CANDU plants, consists of four integrated units with a total output of approximately 3740 MWe located in Ontario, Canada. AECL has completed the concept definition engineering for this design, and will be completing the design integration engineering by the end of 1996. AECL's design philosophy is to build-in product improvements in evolutionary from the initial prototype plants, NPD and Douglas Point, to today's operating CANDU's construction projects and advanced designs. CANDU 9 safety design follows the evolutionary path, including simple improvements based on existing well-proven CANDU safety concepts. The CANDU 9 builds on the experience base for the Darlington reference plant, and on AECL's extensive safety design experience with single unit CANDU 6 power plants. The latest CANDU 6 plants are being built in Korea by KEPCO at Wolsong 2,3 and 4. The Safety improvements for the CANDU 9 power plant are intended to provide the owner-operator with increased assurance of reliable, trouble-free operation, with greater safety margin, with improved public acceptance, and with ease of licensibility

    Teleophthalmology is gaining importance as an effective eye care delivery modality worldwide. In many developing countries, teleophthalmology is being utilized to provide quality eye care to the underserved urban population and the unserved remote rural population. Over the years, technological innovations have led to improvement in evidence and teleophthalmology has evolved from a research tool to a clinical tool. The majority of the current teleophthalmology services concentrate on patient screening and appropriate referral to experts. Specialty care using teleophthalmology services for the pediatric group includes screening as well as providing timely care for retinopathy of prematurity (ROP). Among geriatric eye diseases, specialty teleophthalmology care is focused toward screening and referral for diabetic retinopathy (DR), glaucoma, age-related macular degeneration (ARMD), and other sight-threatening conditions. Comprehensive vision screening and refractive error services are generally covered as part of most of the teleophthalmology methods. Over the past decades, outcome assessment of health care system includes patients’ assessments on their health, care, and services they receive. Outcomes, by and large, remain the ultimate validators of the effectiveness and quality of medical care. Teleophthalmology produces the same desired clinical outcome as the traditional system. Remote portals allow specialists to provide care over a larger region, thereby improving health outcomes and increasing accessibility of specialty care to a larger population. A high satisfaction level and acceptance is reported in the majority of the studies because of increased accessibility and reduced traveling cost and time. Considering the improved quality of patient care and patient satisfaction reported for these telemedicine services, this review explores how teleophthalmology helps to improve patient outcomes.

Memory is the ability of the brain to store, retain and subsequently to recall information received fromthe world. Cognition can be defined as organization of information. It includes acquiring information (perception,selecting (attention, representing (understanding and retaining (memory information and using it to guidebehavior (reasoning and coordination of motor outputs.There are so many conditions associated with memory and cognitive impairment which include Aging,Alzheimer’s disease, Stroke, Stress, Head injuries, Seizures, Benzodiazepines, Brain tumors, Depression, Temporallobe defects and Schizophrenia etc.Choline rich foods can enhance memory and learning and may be useful in improving cognitive abilities. Theseinclude sea foods, liver, egg yolk, soysbeans, broccoli, ash gourd. Coloured fruits and vegetables are good source ofantioxidants which improve concentration. It is advised to decrease the consumption of foods rich in transfats likehydrogenated oils, fried foods, beef, pork, mutton and ice creams and pastries. Such foods increase the deposition offats in the neurons and impair cognition. Tea, cocoa and turmeric are reported to have good nootropic activity i.e.improving memory and learning.

    Full Text Available Purpose: of this paper is to present the results of research programme on improve polymer materials properties by irradiation. This method can be helpful in improving some of mechanical properties and thermal stability of polymers.Design/methodology/approach: Radiation processing involves the use of natural or man-made sources of high energy radiation on an industrial scale. The principle of the radiation processing is the ability of the high energy radiation to produce reactive cations, anions, and free radicals in materials. The industrial application of the radiation processing of plastic and composites includes polymerization, cross-linking and grafting. Radiation processing involves mainly the use of either electron beams from electron accelerators or gamma radiation from Cobalt-60 sources. The big advantage of radiation processing is, that does not make the product radioactive. In this research programme, the properties of natural (not irradiated and irradiated polypropylene (PP, both unfilled and filled with 25% of glass fibres, were compared. Flexural strength, tensile strength, impact strength, thermal stability and complex modulus E* were researched. The injection moulding machine DEMAG – EGROTECH 50 – 200 was used for sample preparation. Irradiation was carried out in the company BGS Beta Gamma Service GmbH Co, KG, Saal am Donau, Germany with the electron rays, electron energy 10 MeV, doses of 15 and 33 kGy.Findings: The most important results are the enormous improvement of the thermal stability and some mechanical properties of irradiated PP.Practical implications: From the practical point of view the most important is the enormous improvement of the thermal stability of irradiated PP. The majority of industrial applications of radiation processing are cross-linking of wire and cable insulations, tube, heat shrink cables, components of tires, composites, moulded products for automotive and electrical industry etc

The aim of this study was to investigate different domains of the QoL in persons with obsessive-compulsive disorder (OCD before and after a multimodal, disorder-specific in- and outpatient treatment. Methods Data of 73 persons with OCD treated in an inpatient setting followed by outpatient treatment were analyzed. The World Health Organization Quality of Life abbreviated (a multidimensional measure of the QoL and the Beck Depression Inventory were administered prior to (baseline and 12 months after the inpatient treatment (follow-up. Results At baseline, participants reported a significantly diminished psychological, social, physical, and global QoL compared to the German general population. Environmental QoL was not impaired in the present sample. The QoL was significantly improved at follow-up, except for social QoL, but remained below norm values. The QoL improvement was predicted by improvements of depressive symptoms. Conclusions The results indicate that persons with OCD suffer from a very low QoL. The QoL was significantly improved after 12 months of intensive state-of-the-art treatment. However, the QoL indices remained considerably lower than population norm values, indicating the need for additional research into novel treatment options for persons with OCD.

    Late-life immigration among seniors for purposes of family reunification is a growing phenomenon in developed countries. Using the World Health Organization's Quality of Life instrument short form (WHOQOL-BREF) and other psychosocial measures related to the political/legal context of immigration, and personal and environmental autonomy (mastery, immigration status, access to transportation, and language barrier), this study examined quality of life (QoL) in Asian Indian seniors (N = 109), who immigrated to the United States to reunite with their adult children. The sample scores on Overall QoL and QoL domains (physical and psychological health, social relationships, and environment) were similar to established norms. Although all QoL domains correlated significantly with Overall QoL at the bivariate level, multivariate analysis showed that only environmental domain contributed significantly to Overall QoL. Linear regressions indicated: Mastery contributed significantly to Overall QoL and all QoL domains; access to transport contributed to Overall QoL, physical health, and environmental QoL; immigration status (a proxy for political/legal context) contributed to environmental QoL whereas language barrier contributed to none. Implications for improving perceptions of QoL, mastery, access to transport and other services are discussed. PMID:27245988

    Investigations conducted by a NASA task force concerning the development of aeronautical fuel-conservation technology are considered. The task force estimated the fuel savings potential, prospects for implementation in the civil air-transport fleet, and the impact of the technology on air-transport fuel use. Propulsion advances are related to existing engines in the fleet, to new production of current engine types, and to new engine designs. Studies aimed at the evolutionary improvement of aerodynamic design and a laminar flow control program are discussed and possibilities concerning the use of composite structural materials are examined.

    CERN Document Server

    D'Agostini, G

    2010-01-01

    This paper reviews the basic ideas behind a Bayesian unfolding published some years ago and improves their implementation. In particular, uncertainties are now treated at all levels by probability density functions and their propagation is performed by Monte Carlo integration. Thus, small numbers are better handled and the final uncertainty does not rely on the assumption of normality. Theoretical and practical issues concerning the iterative use of the algorithm are also discussed. The new program, implemented in the R language, is freely available, together with sample scripts to play with toy models.

    Text Summary In 2004, Centura Health's long-term care centers took part in a pilot project, sponsored by the Centers for Medicare & Medicaid Services, called "Improving Nursing Home Culture through Workforce Retention." A 30-member team comprising Centura leaders and long-term facility staff looked at Centura's eight participating facilities through residents' and employees' eyes. The goal of the team's reflection and subsequent changes was to create a culture in which decisions are focused on resident care and organizational policies are based on respect for employees. At the end of the first year, residents seemed happier and employee satisfaction and involvement increased at all eight Centura facilities. PMID:16519278

    International Nuclear Information System (INIS)

    An improved container is described for transporting radioactive materials, such as irradiated Magnox fuel elements. It has a lid fixed to the container body and at the corners of the lid has shock absorbers that project from the corners and have part-spheroidal shape. The centre of curvature of the surface of the spheroid is positioned within the lid, so that impact loads on a shock absorber tend to hold it to the container rather than dislodge it. The shock absorbers may be Al-Si alloy castings. (U.K.)

    For my CERN Summer Student programme I have been working with ATLAS reprocessing group. Data taken at ATLAS experiment is not only processed after being taken, but is also reprocessed multiple times afterwards. This allows applying new alignments, calibration of detector and using improved or faster algorithms. Reprocessing is usually done in campaigns for different periods of data or for different interest groups. The idea of my project was to simplify the definition of tasks and monitoring of their progress. I created a LIST configuration files generator script in Python and a monitoring webpage for tracking current reprocessing tasks.

Drugs and pharmacology do not fully address motor, cognitive, and psychosocial symptoms; therefore, adjunctive therapies have been researched for their efficacy at addressing these issues. One form of exercise, dance, has received attention because recent studies have demonstrated dance's ability to improve mobility and HRQOL in people with PD. The purpose of this integrative review was to present evidence supporting or refuting improved HRQOL in individuals with PD after participation in a dance- or music-based movement intervention. Potential mechanisms of HRQOL improvement are offered. Search terms including "Parkinson's disease", "dance", "quality of life", "exercise", "dance/movement therapy", and "music" were entered in groupings into PubMed, CINAHL®, EMBASE™, PsycINFO®, Web of Science™, and the Cochrane Library databases. Papers were included if they were randomized controlled trials, pilot studies, or case reports that were related to HRQOL and dance/movement and/or specifically related to determining the mechanisms potentially underlying dance effects. To date, the available research has been inconclusive in demonstrating that dance has a positive impact on HRQOL; however, further research is required. This review suggests that, at the very least, dance has the potential to impact the

    2014-12-01

    Microbes drive processes in the Earth system far exceeding their physical scale, affecting crop yields, water quality, the mobilization of toxic materials, and fundamental aspects of soil biogeochemistry. The tools of synthetic biology have the potential to significantly improve our understanding of microbial Earth system processes: for example, synthetic microbes can be be programmed to report on environmental conditions that stimulate greenhouse gas production, metal oxidation, biofilm formation, pollutant degradation, and microbe-plant symbioses. However, these tools are only rarely deployed in the lab. This research gap arises because synthetically programmed microbes typically report on their environment by producing molecules that are detected optically (e.g., fluorescent proteins). Fluorescent reporters are ideal for petri-dish applications and have fundamentally changed how we study human health, but their usefulness is quite limited in soils where detecting fluorescence is challenging. Here we describe the construction of gas-reporting biosensors, which release nonpolar gases that can be detected in the headspace of incubation experiments. These constructs can be used to probe microbial processes within soils in real-time noninvasive lab experiments. These biosensors can be combined with traditional omics-based approaches to reveal processes controlling soil microbial behavior and lead to improved environmental management decisions.

  7. Improvements to mass spectrometers

    International Nuclear Information System (INIS)

    This invention concerns mass spectrometers and, specifically, an ion beam analyser that facilitates the use of these spectrometers. Its object is to provide an improved apparatus for determining the desorption characteristics by field effect of a sample. It also aims to provide an improved system for carrying out sample analyses by using field effect desorption. Under the invention, facilities are added to the analyser to put out of action a part at least of the separation facilities so that the ion beam coming from the source of ions is not deflected. Detection means are located along the non deflected ion beam to detect the ions of the sample when they effectively appear and finally, actuating facilities are coupled to the out-of-action system so that the mass separation facilities may be brought back into action. This enables the operator to vary the parameters, such as the position of the source (emitter), the temperature and the electric field intensity until ions are released by the unknown sample

Therefore, best practices on reliability improvement in industries that operate in high volume consumer product can be used as a reference toward managing product reliability improvement. In reliability improvement the method should not only focus on how to achieve the expected deliverable but also to sustain the improvement itself and to close the improvement loop. The importance of managing product reliability improvement is on how to ensure that the project moves to the right direction without loosing its flexibility.

  9. The Square Curve Paradigm for Research in Alternative, Complementary, and Holistic Medicine: A Cost-Effective, Easy, and Scientifically Valid Design for Evidence-Based Medicine and Quality Improvement

    Directory of Open Access Journals (Sweden)

    Soren Ventegodt

    2003-01-01

    Full Text Available In this paper we present a new research paradigm for alternative, complementary, and holistic medicine — a low-cost, effective, and scientifically valid design for evidence-based medicine. Our aim is to find the simplest, cheapest, and most practical way to collect data of sufficient quality and validity to determine: (1 which kinds of treatment give a clinically relevant improvement to quality of life, health, and/or functionality; (2 which groups of patients can be aided by alternative, complementary, or holistic medicine; and (3 which therapists have the competence to achieve the clinically relevant improvements. Our solution to the problem is that a positive change in quality of life must be immediate to be taken as caused by an intervention. We define “immediate” as within 1 month of the intervention. If we can demonstrate a positive result with a group of chronic patients (20 or more patients who have had their disease or state of suffering for 1 year or more, who can be significantly helped within 1 month, and the situation is still improved 1 year after, we find it scientifically evidenced that this cure or intervention has helped the patients. We call this characteristic curve a “square curve”. If a global, generic, quality-of-life questionnaire like QOL5 or, even better, a QOL-Health-Ability questionnaire (a quality-of-life questionnaire combined with a self-evaluated health and ability to function questionnaire is administered to the patients before and after the intervention, it is possible to document the effect of an intervention to a cost of only a few thousand Euros/USD. A general acceptance of this new research design will solve the problem that there is not enough money in alternative, complementary, and holistic medicine to pay the normal cost of a biomedical Cochrane study. As financial problems must not hinder the vital research in nonbiomedical medicine, we ask the scientific community to accept this new research

Rigid applicators made of stainless steel of 1.6 mm in diameter were indwelt with a template as usual for 30 hours in 14 patients (group A). Flexible applicators made of polyoxymethylene rosin (POM) of 2.0 mm in diameter were indwelt without a template for 30 hours after the applicator insertion in 6 patients (group B). We made inquiries about lumbago, inconvenience and necessity of assistant help and sleep in the course of therapy, and urinary incontinence and erectile function after the course of therapy as the QOL. The stress during the course of therapy in the patients of group B was obviously less than that of group A. There were no significant differences in urinary incontinence and erectile function after the course of therapy between group A and B. In this study, our trial successfully reduced the stress during the course of therapy in the patients with localized prostate cancer in the course of high-dose rate Iridium-192 brachytherapy.

  13. Towards improved CZT crystals

    International Nuclear Information System (INIS)

    Past experimental efforts to improve CZT crystals for gamma spectrometer applications have been focused on reducing micron-scale defects such as tellurium inclusions and precipitates. While these micron-scale defects are important, experiments have shown that the micron-scale variations in transport can be caused by the formation and aggregation of atomic-scale defects such as dislocations and point defect clusters. Moreover, dislocation cells have been found to act as nucleation sites that cause the formation of large precipitates. To better solve the uniformity problem of CZT, atomic-scale defects must be understood and controlled. To this end, we have begun to develop an atomistic model that can be used to reveal the effects of small-scale defects and to guide experiments for reducing both atomic- and micron-scale (tellurium inclusions and precipitates) defects. Our model will be based upon a bond order potential (BOP) to enable large-scale molecular dynamics simulations of material structures at a high-fidelity level that was not possible with alternative methods. To establish how BOP improves over existing approaches, we report here our recent work on the assessment of two representative literature CdTe interatomic potentials that are currently widely used: the Stillinger-Weber (SW) potential and the Tersoff-Rockett (TR) potential. Careful examinations of phases, defects, and surfaces of the CdTe system were performed. We began our study by using both potentials to evaluate the lattice constants and cohesive energies of various Cd, Te, and CdTe phases including dimer, trimer, chain, square, rhomboid, tetrahedron, diamond-cubic (dc), simple-cubic (sc), body-centered-cubic (bcc), face-centered cubic (fcc), hexagonal-close-packed (hcp), graphite-sheet, A8, zinc-blende (zb), wurtzite (wz), NaCl, CsCl, etc. We then compared the results with our calculations using the density functional theory (DFT) quantum mechanical method. We also evaluated the suitability of the

  14. Improving tumour response

    International Nuclear Information System (INIS)

    Radiation oncology is in the middle of the most exciting developments in its 100-year history. Progress in treatment planning and delivery, in medical imaging and in basic cancer and normal tissue biology is likely to change the indication for radiotherapy as well as the way it is prescribed and delivered. Technological and conceptual advances, in particular the development of the multi-leaf collimator and the concept of inverse treatment planning, have led to the introduction of intensity modulated radiation therapy (IMRT) with its capability to plan and deliver non-uniform dose distributions in the clinic. This has forced us to re-think radiation oncology: refining the indication for radiotherapy, optimizing the prescription of dose distributions and considering how, based on clinical evidence, radiation can best be combined with other treatment modalities, surgery, cytotoxic chemotherapy and biologically targeted therapies. The attraction of radiation therapy as an element of multi-modality cancer therapy is that it induces DNA damage that can be modulated in space and time. Progress in basic cancer biology, genomics and proteomics, as well as biological imaging provides novel avenues for individualization of cancer therapy and for biological optimization of radiotherapy. In improving cancer care, it is the therapeutic ratio, rather than tumour control per se, that must be optimised. Interestingly, the two main avenues for improving the effectiveness of radiotherapy currently being actively pursued in the clinic generally aim at different sides of the therapeutic ratio: 3D conformal radiotherapy and IMRT predominantly aim to reduce normal-tissue side effects - and by doing this, open the way for dose escalation that may lead to increased tumour control rates - whereas combined radio-chemotherapy aims to improve tumour response - while keeping the fingers crossed that this will not increase normal-tissue complications to the same extent. In parallel with these

  16. Mutations in lettuce improvement.

    Science.gov (United States)

    Mou, Beiquan

    2011-01-01

    Lettuce is a major vegetable in western countries. Mutations generated genetic variations and played an important role in the domestication of the crop. Many traits derived from natural and induced mutations, such as dwarfing, early flowering, male sterility, and chlorophyll deficiency, are useful in physiological and genetic studies. Mutants were also used to develop new lettuce products including miniature and herbicide-tolerant cultivars. Mutant analysis was critical in lettuce genomic studies including identification and cloning of disease-resistance genes. Mutagenesis combined with genomic technology may provide powerful tools for the discovery of novel gene alleles. In addition to radiation and chemical mutagens, unconventional approaches such as tissue or protoplast culture, transposable elements, and space flights have been utilized to generate mutants in lettuce. Since mutation breeding is considered nontransgenic, it is more acceptable to consumers and will be explored more in the future for lettuce improvement. PMID:22287955

    Holmes-Rovner, M; Rovner, D R

    2000-08-01

    Patient decision support (PDS) tools or decision aids have been developed as adjuncts to the clinical encounter. Their aim is to support evidence-based patient choice. Clinical trials of PDS tools have used an array of outcome measures to determine efficacy, including knowledge, satisfaction, health status and consistency between patient choice and values. This paper proposes that the correlation between 'subjective expected utility' (SEU) and decision may be the best primary endpoint for trials. SEU is a measure usually used in behavioural decision theory. The paper first describes how decision support tools may use decision analysis to structure the presentation of evidence and guide patient decision-making. Uses of expected utility (EU) are suggested for evaluating PDS tools when improving population health status is the objective. SEU is the theoretically better measure when internal consistency of patient choices is the objective. PMID:11083037

    The relationship of energy and poultry production was explored in three areas: methane production from litter, broiler house insulation, and broiler house HVAC systems. The findings show that while a methane plant would not be popular with individual American poultry producers; the pay back in fuel and fertilizer, if the plant was located in close proximinity to the processing plant, would be favorable. Broiler house insulation has been dramatically improved since the outset of this study. Presently, all new installations in the survey area are the Environmental houses which are fully insulated. HVAC systems have had to keep pace with the introduction of better insulation. The new Environmental houses HVAC systems are fully automated and operating on a positive atmosphere principal. Ammonia and other problems have been kept in check while reducing air changes per house from a high of 7 per hour to as little as 3 per hour.

    ENGLISH ABSTRACT: This paper examines the results of a concerted effort to move to a more rigorous and scientific basis for managing for improved productivity. The point of departure is a question, in the mouth of the chief executive officer of an organization: "How can we improve productivity?" The hypothesis is framed in terms of two contextual factors and six specific factors. The contextual factors are: create a questioning or learning culture, and develop a "cause-effect vision" to motivate questioning. The specific activities of the organization should be characterized by goals, feedback, participation, experimenation, pressure, and perseverance. The results of twelve audits of South African organizations, involving some 200 interviews and 2000 questionnaires, have been used to test the above hypothesis. The paper presents some of these results to indicate support for aspects of the hypothesis.

    Purpose - The purpose of this paper is to present the results of exploratory research designed to develop an awareness of healthcare behaviors, with a view toward improving the customer satisfaction with healthcare services. It examines the relationship between healthcare providers and their consumers/patients/clients. Design/methodology/approach - The study uses a critical incident methodology, with both effective and ineffective behavioral specimens examined across different provider groups. Findings - The effects of these different behaviors on what Berry (1999) identified as the common core values of service organizations are examined, as those values are required to build a lasting service relationship. Also examined are categories of healthcare practice based on the National Quality Strategy priorities. Research limitations/implications - The most obvious is the retrospective nature of the method used. How accurate are patient or consumer memories? Are they capable of making valid judgments of healthcare experiences (Berry and Bendapudi, 2003)? While an obvious limitation, such recollections are clearly important as they may be paramount in following the healthcare practitioners' instructions, loyalty for repeat business, making recommendations to others and the like. Further, studies have shown retrospective reports to be accurate and useful (Miller et al., 1997). Practical implications - With this information, healthcare educators should be in a better position to improve the training offered in their programs and practitioners to better serve their customers. Social implications - The findings would indicate that the human values of excellence, innovation, joy, respect and integrity play a significant role in building a strong service relationship between consumer and healthcare provider. Originality/value - Berry (1999) has argued that the overriding importance in building a lasting service business is human values. This exploratory study has shown how

    Quality of life (QOL), as a relevant area of research in the understanding of heart failure (HF) patient outcomes, has been increasingly studied during the last two decades. The purposes of this review article are to (1) describe QOL in older adults with HF, (2)identify and critique research designed to test interventions to improve QOL, (3) identify gaps in the literature, and (4) provide recommendations for future research. Seventeen studies describing QOL in older adults with HF were identified. Elderly HF patient QOL has been reported to be fair to poor and is worse as compared to a healthy control group. Furthermore, there is some evidence that suggests that QOL is better in older adults than younger adults and worse in women (both older and younger) than in men, although these findings are not consistent across studies. Predictors of QOL and its dimensions in older HF patients included demographic, clinical, and psychosocial variables. Sixteen interventional studies were identified that reported QOL as an outcome in older adults. Findings among randomized clinical trials (RCTs) to improve QOL outcomes in elderly HF patients do not allow strong conclusions about the benefits of the interventions. It must be noted, though, that while not all studies reported improvements in QOL (either significant or as a trend),no studies reported deterioration in QOL with randomization to an intervention versus control. These studies were limited by several methodological issues. While there has been some research of QOL in this elderly cohort, it is paramount that we address methodological issues and thereby improve the scientific rigor of our research, continue to explore QOL in elderly HF patients, and design intervention trials for elders at risk for poor QOL.

    Transport of people, personal belongings and goods in private cars is fundamental to our modern welfare society and economic growth, and has grown steadily over many decades. Motor fuels have been based almost entirely on crude oil for the last century. During the last couple of decades engines built for traditional fuels have become more advanced and efficient; this has reduced fuel consumption by around 40% and emissions by more than 90%. Only in the same time span have we begun to look at alternatives to fossil fuels. Biofuels such as biodiesel, bioethanol, biomethanol and biogas can replace petrol and diesel, and in recent years algae have shown a new potential for diesel fuel. Natural gas is also becoming an interesting fuel due to its large resources worldwide. GTL, CTL and BTL are liquid fuels produced from solid or gaseous sources. GTL and CTL are expensive to produce and not very CO{sub 2}-friendly, but they are easily introduced and need little investment in infrastructure and vehicles. DME is an excellent fuel for diesel engines. Methanol and DME produced from biomass are among the most CO{sub 2}-reducing fuels and at the same time the most energy-efficient renewable fuels. Fuel cell vehicles (FCVs) are currently fuelled by hydrogen, but other fuels are also possible. There are, however, several barriers to the implementation of fuel cell vehicles. In particular, a hydrogen infrastructure needs to be developed. Electric vehicles (EVs) have the advantage that energy conversion is centralised at the power plant where it can be done at optimum efficiency and emissions. EVs have to be charged at home, and also away from home when travelling longer distances. With an acceptable fast charging infrastructure at least 85% of the one-car families in Denmark could be potential EV customers. Range improvements resulting from better batteries are expected to create a large increase in the number of EVs in Denmark between 2020 and 2030. The hybrid electric vehicle

    The Interstate Oil and Gas Compact Commission (IOGCC) engaged in numerous projects outlined under the scope of work discussed in the United States Department of Energy (DOE) grant number DE-FC26-04NT15456 awarded to the IOGCC. Numerous projects were completed that were extremely valuable to state oil and gas agencies as a result of work performed utilizing resources provided by the grant. There are numerous areas in which state agencies still need assistance. This additional assistance will need to be addressed under future scopes of work submitted annually to DOE's Project Officer for this grant. This report discusses the progress of the projects outlined under the grant scope of work for the 2005-2006 areas of interest, which are as follows: Area of Interest No. 1--Regulatory Streamlining and Improvement: This area of interest continues to support IOGCC's regulatory streamlining efforts that include the identification and elimination of unnecessary duplications of efforts between and among state and federal programs dealing with exploration and production on public lands. Area of Interest No. 2--Technology: This area of interest seeks to improve efficiency in states through the identification of technologies that can reduce costs. Area of Interest No. 3--Training and Education: This area of interest is vital to upgrading the skills of regulators and industry alike. Within the National Energy Policy, there are many appropriate training and education opportunities. Education was strongly endorsed by the President's National Energy Policy Development group. Acting through the governors offices, states are very effective conduits for the dissemination of energy education information. While the IOGCC favors the development of a comprehensive, long-term energy education plan, states are also supportive of immediate action on important concerns, such as energy prices, availability and conservation.

    Forecasting how plumes of particles, such as radioactive particles from a nuclear disaster, will be transported and dispersed in the atmosphere is an important but computationally challenging task. During the Fukushima nuclear disaster in Japan, operational plume forecasts were produced each day, but as the emissions continued, previous emissions were not included in the simulations used for forecasts because it became impractical to rerun the simulations each day from the beginning of the accident. Draxler and Rolph examine whether it is possible to improve plume simulation speed and flexibility as conditions and input data change. The authors use a method known as a transfer coefficient matrix approach that allows them to simulate many radionuclides using only a few generic species for the computation. Their simulations work faster by dividing the computation into separate independent segments in such a way that the most computationally time consuming pieces of the calculation need to be done only once. This makes it possible to provide real-time operational plume forecasts by continuously updating the previous simulations as new data become available. They tested their method using data from the Fukushima incident to show that it performed well. (Journal of Geophysical Research-Atmospheres, doi:10.1029/2011JD017205, 2012)

  10. Improved Search Techniques

    2012-01-01

    Thousands of millions of documents are stored and updated daily in the World Wide Web. Most of the information is not efficiently organized to build knowledge from the stored data. Nowadays, search engines are mainly used by users who rely on their skills to look for the information needed. This paper presents different techniques search engine users can apply in Google Search to improve the relevancy of search results. According to the Pew Research Center, the average person spends eight hours a month searching for the right information. For instance, a company that employs 1000 employees wastes $2.5 million dollars on looking for nonexistent and/or not found information. The cost is very high because decisions are made based on the information that is readily available to use. Whenever the information necessary to formulate an argument is not available or found, poor decisions may be made and mistakes will be more likely to occur. Also, the survey indicates that only 56% of Google users feel confident with their current search skills. Moreover, just 76% of the information that is available on the Internet is accurate.

    Effective handovers are vital to patient safety and continuity of care, and this is recognised by several national bodies including the GMC. The existing model at Great Western Hospital (GWH) involved three general surgical teams and a urology team placing their printed patient lists, complete with weekend jobs, in a folder for the on-call team to collect at the weekend. We recognised a need to reduce time searching for patients, jobs and reviews, and to streamline weekend ward rounds. A unified weekend list ordering all surgical patients by ward and bed number was introduced. Discrepancies in the layout of each team's weekday list necessitated the design of a new weekday list to match the weekend list to facilitate the easy transfer of information between the two lists. A colour coding system was also used to highlight specific jobs. Prior to this improvement project only 7.1% of those polled were satisfied with the existing system, after a series of interventions satisfaction increased to 85.7%. The significant increase in overall satisfaction with surgical handover following the introduction of the unified weekend list is promising. Locating patients and identifying jobs is easier and weekend ward rounds can conducted in a more logical and timely fashion. It has also helped facilitate the transition to consultant ward rounds of all surgical inpatients at the weekends with promising feedback from a recent consultants meeting. PMID:26734294

  12. Improving operating room schedules.

    2016-09-01

    Operating rooms (ORs) in US hospitals are costly to staff, generate about 70 % of a hospital's revenues, and operate at a staffed-capacity utilization of 60-70 %. Many hospitals allocate blocks of OR time to individual or groups of surgeons as guaranteed allocation, who book surgeries one at a time in their blocks. The booking procedure frequently results in unused time between surgeries. Realizing that this presents an opportunity to improve OR utilization, hospitals manually reschedule surgery start times one or two days before each day of surgical operations. The purpose of rescheduling is to decrease OR staffing costs, which are determined by the number of concurrently staffed ORs. We formulate the rescheduling problem as a variant of the bin-packing problem with interrelated items, which are the surgeries performed by the same surgeon. We develop a lower bound (LB) construction algorithm and prove that the LB is at least (2/3) of the optimal staffing cost. A key feature of our approach is that we allow hospitals to have two shift lengths. Our analytical results form the basis of a branch-and-bound algorithm, which we test on data obtained from three hospitals. Experiments show that rescheduling saves significant staffing costs.

    Full Text Available The objective of this research is to develop firms’ project manufacturing coordination. The development will be made by centralizing the manufacturing information flows in one system. To be able to centralize information, a deep user need assessment is required. After user needs have been identified, the existing system will be developed to match these needs. The theoretical background is achieved through exploring the literature of project manufacturing, development project success factors and different frameworks and tools for development project execution. The focus of this research is rather in customer need assessment than in system’s technical expertise. To ensure the deep understanding of customer needs this study is executed by action research method. As a result of this research the information system for project manufacturing coordination was developed to respond revealed needs of the stakeholders. The new system improves the quality of the manufacturing information, eliminates waste in manufacturing coordination processes and offers a better visibility to the project manufacturing. Hence it provides a solid base for the further development of project manufacturing.

  15. Cold Lake profitability improvement

    International Nuclear Information System (INIS)

    For the past ten years, Imperial Oil Ltd. has been carrying out a world scale commercial project, using cyclic steam stimulation (CSS) to extract bitumen from the Cold Lake area. Because of the very heavy and viscous nature of Cold Lake bitumen, Imperial Oil has employed CSS as a means of in-situ enhanced recovery. Although this method has been very effective, production has been challenged by the cost of generating and treating steam. To comply with pipeline constraints, Cold Lake bitumen has had to be blended with a diluent. The blended product has been a desirable refinery feedstock, however, it sells for less that light sweet crude, clearly indicating the need for unit cost reduction. Since the start-up of operations nearly a decade ago cost reductions have been achieved in many areas, including production technology, water management, fuel efficiency, services and maintenance, people productivity, electricity costs, and chemical costs. The combined value of these reductions was claimed to be about one third of production costs, resulting in significantly improved competitive position and profitable development of the Cold Lake deposit. 5 figs

  2. CONFORMANCE IMPROVEMENT USING GELS

    Energy Technology Data Exchange (ETDEWEB)

    Randall S. Seright

    2003-09-01

    This report describes work performed during the second year of the project, ''Conformance Improvement Using Gels.'' The project has two objectives. The first objective is to identify gel compositions and conditions that substantially reduce flow through fractures that allow direct channeling between wells, while leaving secondary fractures open so that high fluid injection and production rates can be maintained. The second objective is to optimize treatments in fractured production wells, where the gel must reduce permeability to water much more than that to oil. Pore-level images from X-ray computed microtomography were re-examined for Berea sandstone and porous polyethylene. This analysis suggests that oil penetration through gel-filled pores occurs by a gel-dehydration mechanism, rather than a gel-ripping mechanism. This finding helps to explain why aqueous gels can reduce permeability to water more than to oil. We analyzed a Cr(III)-acetate-HPAM gel treatment in a production well in the Arbuckle formation. The availability of accurate pressure data before, during, and after the treatment was critical for the analysis. After the gel treatment, water productivity was fairly constant at about 20% of the pre-treatment value. However, oil productivity was stimulated by a factor of 18 immediately after the treatment. During the six months after the treatment, oil productivity gradually decreased to approach the pre-treatment value. To explain this behavior, we proposed that the fracture area open to oil flow was increased substantially by the gel treatment, followed by a gradual closing of the fractures during subsequent production. For a conventional Cr(III)-acetate-HPAM gel, the delay between gelant preparation and injection into a fracture impacts the placement, leakoff, and permeability reduction behavior. Formulations placed as partially formed gels showed relatively low pressure gradients during placement, and yet substantially reduced the

    2004-09-30

    This report describes work performed during the third and final year of the project, ''Conformance Improvement Using Gels.'' Corefloods revealed throughput dependencies of permeability reduction by polymers and gels that were much more prolonged during oil flow than water flow. This behavior was explained using simple mobility ratio arguments. A model was developed that quantitatively fits the results and predicts ''clean up'' times for oil productivity when production wells are returned to service after application of a polymer or gel treatment. X-ray computed microtomography studies of gels in strongly water-wet Berea sandstone and strongly oil-wet porous polyethylene suggested that oil penetration through gel-filled pores occurs by a gel-dehydration mechanism, rather than gel-ripping or gel-displacement mechanisms. In contrast, analysis of data from the University of Kansas suggests that the gel-ripping or displacement mechanisms are more important in more permeable, strongly water-wet sandpacks. These findings help to explain why aqueous gels can reduce permeability to water more than to oil under different conditions. Since cement is the most commonly used material for water shutoff, we considered when gels are preferred over cements. Our analysis and experimental results indicated that cement cannot be expected to completely fill (top to bottom) a vertical fracture of any width, except near the wellbore. For vertical fractures with apertures less than 4 mm, the cement slurry will simply not penetrate very far into the fracture. For vertical fractures with apertures greater than 4 mm, the slurry may penetrate a substantial distance into the bottom part of the fracture. However, except near the wellbore, the upper part of the fracture will remain open due to gravity segregation. We compared various approaches to plugging fractures using gels, including (1) varying polymer content, (2) varying placement (extrusion) rate

  4. Improving the bottom line

    International Nuclear Information System (INIS)

    With slower sales in North America and Europe, manufacturers are looking to supply power equipment in the expanding global markets. In doing so, they are finding opportunities and challenges. Competition is tougher in these markets; as well, each market has its own demands. Independent Energy recently spoke with a number of the top manufacturing companies and several system packagers about the markets for power equipment. The topics ranged from higher efficiencies and lower emissions on gas turbines to larger boilers. A growing need for cleaner combustion technologies in many emerging nations, are leading vendors to keep research and development (R ampersand D) budgets at the top of priority lists. In order to find ways to meet cleaner, more efficient demands, some of the equipment industry's leaders are renewing old partnerships and making new ones through alliances and joint ventures. Combining R ampersand D efforts and offering equipment delivery from points around the world instead of one central source is crucial to success in these expanding markets. As well, these alliances offer manufacturers the opportunity to find partners in the countries where much of the new power generation supply will be built. This makes doing business with local or state utilities - and developers who also are seeking local partners - less risky. At the same time, it offers opportunities for these companies to expand into new markets and provide equipment from a local level, boosting economic growth in emerging nations. As manufacturers adjust their market positions, they prepare themselves for an expanding world marketplace which demands more competitive, more efficient and constantly improving ways of doing business

    Research on how implant surface shape contributes to long-term stability after implantation is important in the field of orthopaedics. In particular, technology that controls various bone quality parameters and voluntary bone inducement in implant surroundings should be developed for the next generation of implants and this will improve the patient's quality of life (QOL). For this research, we focused on the inducement of the appropriate alignment for biological apatite (BAp) crystallites and related collagen (Col.) fibres as a bone quality parameter. In this study, we predicted that when stress is applied to bone, the BAp/Col. preferential alignment can be formed if osteocytes are in an environment that is aligned with the principle stress vector. We tested this idea by introducing grooves in the principal stress direction on the surface of an implant. This work thus analyzes the effect of stress transmission by a load at the proximal femur on the bone inside and near the grooves by using mechanical simulation in which groove angles can be changed on the implant surface. Coordinate data from the mechanical simulation of the combined bone/implant environment was verified against the coordinate data obtained by CT scans of actual canine bone. Results suggest that the tendency of stress transmission differs depending on the position and angle of the grooves and based on a vector diagram of the maximum and minimum principal stresses. The simulation was able to predict bone dynamics in vivo and enabled a best design of an implant to control the BAp/Col. alignment as an index of bone quality.

    The Interstate Electrification Improvement Project, publicly known as the Shorepower Truck Electrification Project (STEP), started in May 2011 and ended in March 2015. The project grant was awarded by the Department of Energy’s Vehicles Technology Office in the amount of $22.2 million. It had three overarching missions: 1. Reduce the idling of Class 8 tractors when parked at truck stops, to reduce diesel fuel consumption and thus U.S. dependence on foreign petroleum; 2. Stimulate job creation and economic activity as part of the American Reinvestment and Recovery Act of 2009; 3. Reduce greenhouse gas emissions (GHG) from diesel combustion and the carbon footprint of the truck transportation industry. The project design was straightforward. First, build fifty Truck Stop Electrification (TSE) facilities in truck stop parking lots across the country so trucks could plug-in to 110V, 220V, or 480VAC, and shut down the engine instead of idling. These facilities were strategically located at fifty truck stops along major U.S. Interstates with heavy truck traffic. Approximately 1,350 connection points were installed, including 150 high-voltage electric standby Transport Refrigeration Unit (eTRU) plugs--eTRUs are capable of plugging in to shore power1 to cool the refrigerated trailer for loads such as produce, meats and ice cream. Second, the project provided financial incentives on idle reduction equipment to 5,000 trucks in the form of rebates, to install equipment compatible with shore power. This equipment enables drivers to shut down the main engine when parked, to heat or cool their cab, charge batteries, or use other household appliances without idling—a common practice that uses approximately 1 gallon of diesel per hour. The rebate recipients were intended to be the first fleets to plug into Shorepower to save diesel fuel and ensure there is significant population of shore power capable trucks. This two part project was designed to complement each other by

    An outcome questionnaire that is patient-centred should encompass the aims, values and treatment effects that are prioritised by individuals, and should enable each individual to provide an unambiguous assessment of change over time. There is little evidence about how well outcome questionnaires perform in this regard. This paper describes how interviews that combined in-depth enquiry and cognitive techniques were used to explore patients' experiences of completing three outcome questionnaires over a 6 month period. The 23 interviewees all had chronic disease and were receiving acupuncture treatment for the first time. Many of the problems uncovered by this study can be ameliorated by attention to questionnaire design. For example, by the provision of at least five response options, by being explicit about including co-morbidity, and by measuring medication change as a separate outcome. The study also highlighted more fundamental conceptual difficulties, such as response shift and the respondent's conflict between scoring external function and internal distress (what they did, vs. what they felt). These issues relate to the co-existence of different perspectives and the impossibility of reducing health status to one 'single truth'. The study concludes that qualitative evaluations have an important role to play in questionnaire design and development and are likely to lead to more modest and realistic appraisals of outcome questionnaire performance.

    AIM: To summarize the empirical research on assessing quality of life (QOL) in patients with gastric carcinoma. METHODS: Literature searches were conducted in MedLine from 1966 to February 2004. RESULTS: Twenty-six studies were identified. QOL was used as an outcome measure in virtually all identified studies, such as those examining the effects of gastric cancer and various medical or surgical treatments in the patients. QOL was assessed mainly with generic measures; the social dimensions of QOL were largely neglected. The lack of gastric cancer-specific QOL measures hampers QOL research up to now. The gastric cancer-specific EORTCQLQ-STO22 and the FACT-Ga are important additions to the arsenal of disease-specific QOL measures. In most of the studies, the label QOL is used for questionnaires, which only assess symptoms or performance status, or are physician-reported rather than patient-reported outcomes. CONCLUSION: QOL in patients with gastric cancer deserves more systematic studies, especially as one of the outcome measures in randomized clinical trials. Results of studies that include QOL in patients with gastric cancer should be applied in clinical care, which aims at improving QOL of these patients.

    Full Text Available There has been much research where the flow of patients was improved, but most of this study is case-specific and only a few papers offer guidelines for patient flow analysis and improvement. In this study a general framework for the analysis and improvement of patient flow is presented, based on a literature review and on experience from a case study in a hospital in Mexico dealing with identifying improvement opportunities that reduced waiting times in the obstetrics/gynecology area of the emergency department. The framework involves an initial analysis using basic tools followed by the selection of a strategy based on system complexity; financial investment required and team participation. The alternative strategies considered were use of advanced analysis tools; use of kaizen events; or direct recommendations. The aim of the framework is to serve as guideline in patient flow improvement projects by helping select the most appropriate improvement path, resulting in project success.

    Health care organizations are experiencing increasing internal and external pressures to improve the quality of care that they provide. However, there is not a framework that can be used to help understand the value of quality improvement projects and to prioritize competing projects. By understanding the current processes, costs and outcomes of care, enumerating the costs and benefits of change, anticipating the timing of the costs and benefits, and performing a financial analysis, quality improvement efforts can be evaluated as investments. Only by understanding and adapting to the financial environments in which health care organizations operate can continuous quality improvement in health care succeed. PMID:12512466

    Full Text Available Background/Aim. It has been observed that a large number of patients with low urinary tract symptoms due to benign prostatic hyperplasia (LUTS/BPH has been treated with a combination of tamsulosin (TAM + Serenoa repens (SR (TAM + SR. The aim of this study was to compare a combination TAM + SR with TAM and SR alone, to see if there was any difference in efficacy and tolerance of each in patients with LUTS/BPH. Methods. In this prospective study patients had to have prostate volume (PV 3, a maximal flow rate (Qmax of 5-15 mL/s, with post voiding residual volume (PVR < 150 mL and serum prostatic antigen (PSA < 4 ng/mL. TAM (0.4 mg was administered once a day, SR (320 mg daily or SR (320 mg + TAM (0.4 mg daily for a median period of 6 months. Results. A total of 297 patients were recruited, whereas 265 patients were fully available: 87 into the group TAM, 97 into the group SR and 81 into the group TAM + SR. There was no statistically significant difference between the treatment groups in the sense of demographic and other baseline parameters. No difference was found among the 3 treatment groups, neither in the major endpoint of the study in the sense of a change between baseline and final evaluation in total IPSS, obstructive and irritative subscores, improvement of QoLs, increase in Qmax, nor for the second endpoint including diminution of PV, PSA and PVR. During the treatment period 20 (23% of the patients managed with TAM and 17 (21% with TAM + SR had drug-treated with related adverse reactions. No adverse effect was detected in the group SR. Conclusion. Treatment of BPH by both SR and TAM seems to be efficacious alone. None of them had superiority over another and, additionally, a combined therapy (TAM + SR does not provide extra benefits. Furthermore, SR is a well-tolerated agent that can be used alternatively in the treatment of LUTS/BPH.

    The term Quality of Life (QoL) has been increasingly used in medical and philosophical literatures for the past four decades. The purpose of this article is to analyze how QoL is being used in medicine and in philosophy to understand its current status. In the 1960s and 1970s new technologies raised new questions for clinicians, so they used QoL as a parameter for making decisions in health issues. Consequently, researchers focused their interest on the construction and testing of instruments designed to measure health and QoL. However, all these instruments showed some conceptual and methodological problems that made the use of QoL in medicine difficult. While some researchers considered QoL an "idiosyncratic mystery", others believed that QoL was useful in implementing the patient's point of view into clinical practice and they suggested improving QoL's definition and methodology. In the 1980s, some consequentialist philosophers used QoL to formulate moral judgment, in particular they justified infanticide for some severely handicapped infants, and both euthanasia and suspension of life-sustaining treatment using QoL. In the 1990s, welfarist philosophers opened a new debate about QoL and they associated it with health and happiness. These philosophers developed QoL and those other concepts as subjectivist notions; consequently their definition and their measurements pose challenges. Afterwards researchers' interest in theoretical issues regarding QoL has fallen; nevertheless, physicians have continued to use QoL in clinical practice. PMID:21717042

    Although ADHD significantly affects the quality of life (QoL) of patients and their families, QoL in children with ADHD has rarely been investigated in association with psychopathological profile, and the relationship remains unclear. The open-label OBSEER study evaluated the effectiveness and tolerability of Equasym XL(®), a modified-release methylphenidate, in routine care of children and adolescents (aged 6-17 years) with ADHD. At baseline, questionnaires assessing psychopathological profile (Strengths and Difficulties Questionnaire, SDQ; parental ratings) and QoL (KINDL; parent, child or adolescent versions) were completed; QoL was reassessed at final visit. We analysed the relationship between psychopathology and parent/patient-rated QoL in ADHD at baseline. Data from 721 consecutively referred children and adolescents were analysed. QoL was similarly low from parent and self-ratings and independent of severity on the SDQ subscale hyperactivity/inattention. Self-ratings indicated that additional conduct disorder was associated with further reduction in QoL. Similarly, children with high scores from parent and adolescent ratings on the SDQ subscale conduct problems had reduced QoL on some KINDL subscales. Adolescents with ADHD not receiving medication at baseline reported lower QoL than those already on medication. Results show that children and adolescents with ADHD have low QoL, independent of core symptom severity. Additional conduct problems may further impact QoL negatively, while ADHD medication use may show a trend towards improved QoL. Not all psychopathological problems associated with ADHD affect QoL similarly. As parents appear to have a less critical view of QoL compared with children's self-ratings, both parent and child ratings should be included in clinical assessments. PMID:21901415

    Quality improvement (QI) using a clinical microsystems approach provides cystic fibrosis (CF) centers the opportunity to make a significant positive impact on the health of their patients. The availability of center-specific outcomes data and the support of the Cystic Fibrosis Foundation are important advantages for these quality improvement efforts. This article illustrates how the clinical microsystems methodology can improve care delivery and outcomes by describing the gradual application of quality improvement principles over the past 5 years by the CF team at the Lewis Walker Cystic Fibrosis Center at Akron Children's Hospital in Akron, Ohio. Using the example of a project to improve the pulmonary function of the pediatric patients at our center as a framework, we describe the QI process from the initial team-building phase, through the assessment of care processes, standardization of care, and developing a culture of continuous improvement. We outline how enthusiastic commitment from physician leadership, clinical managers and central administration, the availability of coaches, and an appreciation of the importance of measurement, patient involvement, communication, and standardization are critical components for successful process improvement.

    post S and 20 pts post RT; at 6 months (mos) from the start of induction CT it 7 pts on S and RT arms each; at 12 mos, 10 and 8 pts S and RT, respectively. QOL was improved in pts that experienced palliation of hemoptysis (p<0.05); palliation of cough also improved QOL (p<0.01). Patients that achieved a response to induction CT had improved QOL over baseline (p<0.025); pts not achieving a response did not significantly change from baseline QOL. On average post RT and post S pts did not change in QOL from baseline. Response to therapy did not correlate with improved QOL. Pts experiencing any lung or esophageal toxicity had a deterioration in QOL, though not statistically significant. At six months post therapy, RT and S pts had worse QOL compared to pretreatment, but had improved by 1 year. Pts with a response to therapy at 1 year had improved QOL, though not statistically significant. Conclusion: KPS and gender influenced initial QOL reports and should be stratification factors in future QOL studies in NSCLC. Response to therapy is correlated with improved QOL, although immediate side-effects of therapy may outweigh the importance of response. In the long-term, pts in response report an improvement in QOL from pretreatment levels. The overall importance for QOL of palliation versus cure needs to be further adressed in NSCLC pts

    International Nuclear Information System (INIS)

    After 1991, when Lithuania became independent, the new safety improvement activities were initiated. Lithuania committed its responsibility for Ignalina NPP safety. However, it was lack of money for adequate safety improvement. Countries of Western Europe, USA and IAEA assisted Lithuania to carry out a comprehensive Ignalina NPP safety improvement program. Agreement with EBRD was signed in 1994. As a result of some bilateral and multilateral cooperation projects the Ignalina NPP Safety Improvement Programme (SIP-1) was accepted in 1993.This program was being implemented during 1993-1996. The Safety Analysis Report was issued in 1996. Review of the SAR was performed and RSR report was issued. On basis of both documents the Ignalina Safety Panel prepared recommendations for Lithuanian Government. These documents were used as a basis for the Safety Improvement Programme No.2. SIP-2 was accepted in 1997 and shall be finished in 2000

    Full Text Available INTRODUCTION The incidence of patients presenting with advanced pelvic malignancy with obstructive uropathy is high in our country. Relentless progress of the malignancy will cause deterioration of renal function, aggravation of pain, infection, deterioration of Quality of Life (QOL, uremia and death. Decreased renal function is considered as a contraindication for palliative chemo and radiotherapy. However urinary diversion in these patients will lead to improvement in renal function and may help in administration of palliative therapy and thus, improve the quality of life of these patients. MATERIALS AND METHODS The present study includes the obstructive uropathy patients secondary to pelvic malignancy referred to our institution for urinary diversion between Jan 2010 to Dec 2014. Total 40 patients were included, of which, 25 patients underwent PCN, 9 patients retrograde DJ stenting, 4 patients refused the treatment, 2 patients were not fit for any intervention due to coagulopathy & comorbid conditions. Of 34 treated patients, 30 were female patients and 4 were male patients. All the patients were explained about the procedure and proper consent taken. Laboratory investigations like CBC, coagulation profile, LFT, routine urine analysis, urine C&S and serum electrolytes were carried out. Haemodialysis was done for 10 patients whose serum creatinine was >6mg% & potassium >6meq. USG guided PCN insertion was done in 8 patients, and in those who failed in this procedure, fluoroscopic C-ARM guided PCN insertion done in 17 patients. Post operatively RFT and serum electrolytes were assessed on 3, 7, 15, & 30th day. PCN catheter was changed once in 3 months. RESULTS 8 patients succeeded in USG guided PCN insertion and 17 patients who failed USG PCN insertion, was done under C–Arm guidance. 3 patients received blood transfusion. No deaths were seen during or post procedure in the hospital. Renal functions improved and normalised in most of the

  16. Improvements in automotive fuel economy

    Borcherts, R.H.; Stadler, H.L.; Brehob, W.M.; Auiler, J.E.

    1978-01-01

    Significant improvements in automotive fuel economy can be obtained by reductions in weight, aerodynamic drag (better streamlining) and rolling resistance (tire improvements) as well as improvements in engine and powertrain efficiency. As applied to a six-passenger 3700 lb present day vehicle powered with a 250 CID six-cylinder engine through an automatic transmission, the improvements in EPA M/H fuel economy for 1% reductions in either weight, aerodynamic drag or rolling resistance are projected to be 0.75%, 0.35% and 0.28% respectively. This is under the constraints of constant performance and equal emissions. The extent to which large changes in these parameters can be obtained resulting in significant improvements in fuel economy depends not only upon solving manufacturing and technical problems related to costs but also upon government regulations and customer acceptance in the marketplace. If large reductions in these parameters could be accomplished along with realistic improvements in engine and powertrain efficiency, significant improvements in fuel economy could be achieved.

    Quality improvement teams are different from other work groups in their purpose, leadership, membership, training, procedures, and dynamics. To have effective quality improvement teams, health care organizations must focus on six key process variables, with particular attention to group dynamics. Quality improvement teams progress through the "traditional" stages of team development--forming, storming, norming, and performing--with a "special stage" of closing. Within each stage, there are two core dimensions--team process ("relationship" issues) and the project itself ("task" issues)--and critical tasks that need to be performed by the Quality Council, team members, team leader, and the facilitator.

  3. Evaluation of quality of life and psychological response in cancer patients treated with radiotherapy

    International Nuclear Information System (INIS)

    The importance of the quality of life (QOL) and mental condition of patients being treated for cancer is now recognized. In this study, we evaluated QOL and mental condition in patients with cancer before and after radiotherapy. The subjects were 170 patients who had undergone radiotherapy. The examination of QOL was performed using the quality of life questionnaire for cancer patients treated with anticancer drugs (QOL-ACD), and mental condition (anxiety and depression) was examined using the hospital anxiety and depression scale (HADS). These examinations were performed at the start of radiotherapy and immediately after radiotherapy. The QOL score was slightly higher in all patients after the completion of radiotherapy than before the start of radiotherapy. In the palliative radiotherapy group, QOL score was significantly improved by treatment. Anxiety and depression were improved after radiotherapy. There was a correlation between the degrees of improvement of the HADS and QOL score. We could treat cancer patients by radiotherapy without reducing their QOL, and improvement in QOL was significant in the palliative radiotherapy group. Mental condition was also improved after radiotherapy. (author)

    A previous study showed that imposing economic restrictions improves the forecasting ability of food demand systems, thus warranting their use even when they are rejected in-sample. This article evaluates whether this result is due to economic restrictions enhancing degrees of freedom or containing nonsample information. Results indicate that restrictions improve forecasting ability even when they are not derived from economic theory, but theoretical restrictions forecast best.

    Cannulation of arteriovenous fistulae is technically more challenging than cannulation of arteriovenous grafts. With the advent of the National Vascular Improvement Initiative, Fistula First, the United States has seen an increase in the number of arteriovenous fistulae. The problem we now face is how to refocus and reeducate nurses to the intricacies of arteriovenous fistula cannulation. Through evidenced-based practice and current best-demonstrated practices, this article will provide the tools needed to improve arteriovenous fistulae cannulation skills. PMID:16425809

    Selective breeding and improved nutritional management over the past 20-30 years has resulted in dramatic improvements in growth efficiency for pigs and poultry, particularly lean tissue growth. However, this has been achieved using high-quality feed ingredients, such as wheat and soya that are also used for human consumption and more recently biofuels production. Ruminants on the other hand are less efficient, but are normally fed poorer quality ingredients that cannot be digested by human subjects, such as grass or silage. The challenges therefore are to: (i) maintain the current efficiency of growth of pigs and poultry, but using more ingredients not needed to feed the increasing human population or for the production of biofuels; (ii) improve the efficiency of growth in ruminants; (iii) at the same time produce animal products (meat, milk and eggs) of equal or improved quality. This review will describe the use of: (a) enzyme additives for animal feeds, to improve feed digestibility; (b) known growth promoting agents, such as growth hormone, β-agonists and anabolic steroids, currently banned in the European Union but used in other parts of the world; (c) recent transcriptomic studies into molecular mechanisms for improved growth efficiency via low residual feed intake. In doing so, the use of genetic manipulation in animals will also be discussed. PMID:27087253

The present study is a consequence of an imperative requirement from the nursing staff, which, in closecooperation with the surgeon, the physical therapist and the psychologist intend a better understanding regardingpatient perception of the so-called post-discharge health-related quality of life (HRQOL. Material and method: Ourstudy included a pilot retrospective study performed on a group of 26 patients investigated and operated for total hipreplacement, between June 2010 – June 2011 in the Orthopaedic Clinic in the Rehabilitation Hospital in Iasi, Romania.We have evaluated QOL by applying a WOMAC scoring system and questionnaire to this group of patiens. We haveobtained data from those patients in preoperative step but also at 3 months postoperatively. All patients in this studywere operated by the same orthopaedic surgeon and followed the same rehabilitation program started during hospitalstay and continued under thorough supervision at home or in hospital linked institutions. Preoperative andpostoperative at 3 months data were reported and gathered for each patient in the form of Western Ontario andMcMaster Universities Osteoarthritis Index (WOMAC scores. Results: Following this evaluation we have looked foreach main index correlation in the WOMAC pre and postoperatively. For the pain item correlations we have obtained a0.617 between preoperative and 3 months postoperative pain. For the stiffness item correlations we have obtained a0.071 between preoperative and 3 months postoperative stiffness. For the functionality item correlations we haveobtained a 0.808 between preoperative and 3 months postoperative pain.

    Full Text Available Obstructive sleep apnea (OSA is associated with significant cardiovascular andcerebrovascular morbidity and mortality. Usual parameters studied in sleep laboratoryare unable to measure overall impact of OSA on human life. Consequently, it isimportant to measure Quality of Life (QoL in OSA. QoL can be measured with genericinstruments like SF-36 or OSA specific questionnaires like Calgary Sleep ApneaQuality of Life (SAQLI questionnaire. Most of the studies suggest that there issignificant impairment of QoL in patients of OSA. But the present evidence suggeststhat impairment in QoL is not proportional to severity of OSA. There is no consensus onthe question of improvement in QoL with Continuous Positive Airway Pressure(CPAP therapy. A recent Cochrane review concluded that CPAP improves QoL inpeople with moderate and severe OSA.Key words : Obstructive sleep apnea, Quality of Life, Continuous Positive AirwayPressure

    Full Text Available Based on the performance analysis technique developed in Part I, this paper presents improvability indicators for assembly lines with unreliable machines. In particular, it shows that assembly lines are unimprovable with respect to workforce re-distribution if each buffer is, on the average, close to being half full. These lines are unimprovable with respect to buffer capacity re-distribution if each machine is starved and blocked with almost equal frequency. In addition, the paper provides indicators for identification of bottleneck machines and bottleneck buffers. Finally, the paper reports on an application of these improvability indicators in a case study at an automotive components plant.

  16. Longitudinal Assessments of Quality of Life in Endometrial Cancer Patients: Effect of Surgical Approach and Adjuvant Radiotherapy

    International Nuclear Information System (INIS)

    Purpose: Adjuvant radiotherapy (RT) is often considered for endometrial cancer. We studied the effect of RT and surgical treatment on patients' quality of life (QOL). Methods and Materials: All patients referred to the gynecologic oncology clinics with biopsy findings showing endometrial cancer were recruited. QOL assessments were performed using the European Organization for Research and Treatment of Cancer QOL questionnaire-C30, version 3. Assessments were obtained at study entry and at regular 3-month intervals for a maximum of 2 years. Open-ended telephone interviews were done every 6 months. Linear mixed regression models were built using QOL domain scores as dependent variables, with the predictors of surgical treatment and adjuvant RT type. Results: A total of 40 patients were recruited; 80% of the surgeries were performed by laparotomy. Significant improvements were seen in most QOL domains with increased time from treatment. Adjuvant RT resulted in significantly more severe bowel symptoms and improvement in insomnia compared with conservative follow-up. No significant adverse effect from adjuvant RT was seen on the overall QOL. Bowel symptoms were significantly increased in patients treated with laparotomy compared with laparoscopy in the patients treated with whole pelvic RT. Qualitatively, about one-half of the patients noted improvements in their overall QOL during follow-up, with easy fatigability the most prevalent. Conclusion: No significant adverse effect was seen on patients' overall QOL with adjuvant pelvic RT after the recovery period. The acute adverse effects on patients' QOL significantly improved with an increasing interval from diagnosis.

  17. Evolutionary CANDU 9 plant improvements

    International Nuclear Information System (INIS)

    The CANDU 9 is a 935 MW(e) nuclear power plant (NPP) based on the multi-unit Darlington and Bruce B designs with additional enhancements from our ongoing engineering and research programs. Added to the advantages of using proven systems and components, CANDU 9 offers improvement features with enhanced safety, improved operability and maintenance including a control centre with advanced man-machine interface, and improved project delivery in both engineering and construction. The CANDU 9 NPP design incorporated safety enhancements through careful attention to emerging licensing and safety issues. The designers assessed, revised and evolved such systems as the moderator, end shield, containment and emergency core cooling (ECC) systems while providing an integrated final design that is more passive and severe-accident-immune. AECL uses a feedback process to incorporate lessons learned from operating plants, from current projects experiences and from the implementation or construction phase of previous projects. Most of the requirements for design improvements are based on a systematic review of current operating CANDU stations in the areas of design and reliability, operability, and maintainability. The CANDU 9 Control Centre provides plant staff with improved operability and maintainability capabilities due to the combination of systematic design with human factors engineering and enhanced operating and diagnostics features. The use of advanced engineering tools and modem construction methods will reduce project implementation risk on project costs and schedules. (author)
