    Abstract Sodium alendronate is a bisphosphonate drug that exerts antiresorptive action and is used to treat osteoporosis. Objective The aim of this study was to evaluate the bone repair process at the bone/implant interface of osteoporotic rats treated with sodium alendronate through the analysis of microtomography, real time polymerase chain reactions and immunohistochemistry (RUNX2 protein, bone sialoprotein (BSP), alkaline phosphatase, osteopontin and osteocalcin). Material and Methods A total of 42 rats were used and divided in to the following experimental groups: CTL: control group (rats submitted to fictitious surgery and fed with a balanced diet), OST: osteoporosis group (rats submitted to a bilateral ovariectomy and fed with a low calcium diet) and ALE: alendronate group (rats submitted to a bilateral ovariectomy, fed with a low calcium diet and treated with sodium alendronate). A surface treated implant was installed in both tibial metaphyses of each rat. Euthanasia of the animals was conducted at 14 (immunhostochemistry) and 42 days (immunohistochemistry, micro CT and PCR). Data were subjected to statistical analysis with a 5% significance level. Results Bone volume (BV) and total pore volume were higher for ALE group (P<0.05). Molecular data for RUNX2 and BSP proteins were significantly expressed in the ALE group (P<0.05), in comparison with the other groups. ALP expression was higher in the CTL group (P<0.05). The immunostaining for RUNX2 and osteopontin was positive in the osteoblastic lineage cells of neoformed bone for the CTL and ALE groups in both periods (14 and 42 days). Alkaline phosphatase presented a lower staining area in the OST group compared to the CTL in both periods and the ALE at 42 days. Conclusion There was a decrease of osteocalcin precipitation at 42 days for the ALE and OST groups. Therefore, treatment with short-term sodium alendronate improved bone repair around the implants installed in the tibia of osteoporotic rats. PMID

    A randomized controlled trial was conducted to determine the effect of 6 months of whole body vibration (WBV) exercise on physical function in postmenopausal osteoporotic women treated with alendronate. Fifty-two ambulatory postmenopausal women with osteoporosis (mean age: 74.2 years, range: 51-91 years) were randomly divided into two groups: an exercise group and a control group. A four-minute WBV exercise was performed two days per week only in the exercise group. No exercise was performed in the control group. All the women were treated with alendronate. After 6 months of the WBV exercise, the indices for flexibility, body balance, and walking velocity were significantly improved in the exercise group compared with the control group. The exercise was safe and well tolerated. The reductions in serum alkaline phosphatase and urinary cross-linked N-terminal telopeptides of type I collagen during the 6-month period were comparable between the two groups. The present study showed the benefit and safety of WBV exercise for improving physical function in postmenopausal osteoporotic women treated with alendronate.

    Clinical evidence suggests that, compared with alendronate, risedronate reduces fracture risk faster and more potently, with less bone mass gain. We tested the hypothesis that risedronate improves bone quality faster than alendronate using calcium-deficient, ovariectomized (OVX) rats. Female Sprague-Dawley rats at 24 weeks of age were divided into sham-operated and OVX groups and fed a low-calcium (0.05%) diet under paired feeding. After 12 weeks, OVX rats were divided into five groups and treated with vehicle, risedronate (3.5 and 17.5 μg/kg/week, s.c.) or alendronate (7 and 35 μg/kg/week, s.c.). Rats were killed 6-8 weeks later and the bone architecture and strength of the left femur were evaluated by micro-computed tomography and a three-point bending test. Trabecular bone mineral density (BMD), number and thickness were significantly lower in OVX rats than in the sham-operated group. Cortical BMD, bone area (Ct.Ar), and thickness (Ct.Th) were similarly decreased. Risedronate significantly improved Ct.Ar (+8%) and Ct.Th (+9%) at 6 weeks, while alendronate only caused a significant improvement in Ct.Ar (+8% at 6 weeks) and only at the higher dose. At 8 weeks, both risedronate and alendronate significantly increased trabecular BMD compared with the vehicle. Bone strength parameters showed a significant correlation between Ct.Ar and Ct.Th. Risedronate significantly improved maximum load at 6 weeks, while alendronate failed to produce any significant changes. Our results suggest that risedronate is superior to alendronate at improving cortical bone architecture and strength, and that enhanced bone quality partly accounts for risedronate's efficacy.

  7. Alendronate Can Improve Bone Alterations in Experimental Diabetes by Preventing Antiosteogenic, Antichondrogenic, and Proadipocytic Effects of AGEs on Bone Marrow Progenitor Cells

    Science.gov (United States)

    2016-01-01

    Bisphosphonates such as alendronate are antiosteoporotic drugs that inhibit the activity of bone-resorbing osteoclasts and secondarily promote osteoblastic function. Diabetes increases bone-matrix-associated advanced glycation end products (AGEs) that impair bone marrow progenitor cell (BMPC) osteogenic potential and decrease bone quality. Here we investigated the in vitro effect of alendronate and/or AGEs on the osteoblastogenic, adipogenic, and chondrogenic potential of BMPC isolated from nondiabetic untreated rats. We also evaluated the in vivo effect of alendronate (administered orally to rats with insulin-deficient Diabetes) on long-bone microarchitecture and BMPC multilineage potential. In vitro, the osteogenesis (Runx2, alkaline phosphatase, type 1 collagen, and mineralization) and chondrogenesis (glycosaminoglycan production) of BMPC were both decreased by AGEs, while coincubation with alendronate prevented these effects. The adipogenesis of BMPC (PPARγ, intracellular triglycerides, and lipase) was increased by AGEs, and this was prevented by coincubation with alendronate. In vivo, experimental Diabetes (a) decreased femoral trabecular bone area, osteocyte density, and osteoclastic TRAP activity; (b) increased bone marrow adiposity; and (c) deregulated BMPC phenotypic potential (increasing adipogenesis and decreasing osteogenesis and chondrogenesis). Orally administered alendronate prevented all these Diabetes-induced effects on bone. Thus, alendronate could improve bone alterations in diabetic rats by preventing the antiosteogenic, antichondrogenic, and proadipocytic effects of AGEs on BMPC. PMID:27840829

    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

    Osteoporosis is associated with compromised quality of life (QOL), to which pain has the most important contribution. Elcatonin, a derivative of calcitonin, is widely used in the treatment of osteoporosis in two ways. One is as the inhibitor of osteoclastic bone resorption. The other is for osteoporosis-related pain based on the unique analgesic effects of elcatonin. Since pain is subjective in nature, and QOL is the only clinical outcome representing the patients' subjective perception of health status, pain associated with osteoporosis would be best evaluated based on QOL assessment. Evidence based medicine gives the highest remarks to the double-blinded, randomized controlled trial, which, however, cannot be free from methodological problems on some occasions. For example, it is practically impossible to remain blinded in the trial of a potent analgesia, which in turn causes biases. Thus, the significance of taking the patients' preference into account is increasingly acknowledged. In this study, 45 osteoporotic patients were given brochures describing the pros and cons on the three treatment choices; calcium and alfacalcidol, additional use of elcatonin, and additional use of bisphosphonate. Those who favored elcatonin were older, had more vertebral fractures, and lower QOL scores. QOL was evaluated before and three months after the treatment using SF-8; the most widely used generic questionnaire, and RDQ; a lumbago-specific measure. Elcatonin treatment improved physical function, general health, and vitality of SF-8, and RDQ score. Although this is a preliminary study, our results suggest that patients with vertebral fracture(s) have impaired QOL and more likely to favor elcatonin treatment expecting analgesia.

    Context • Combined treatment with an extract of Lentinula edodes mycelia (LEM) and chemotherapy has been reported to improve quality of life (QOL) and immunological function in cancer patients. However, those effects have not been elucidated for patients receiving cancer immunotherapy. Objective • The present study intended to investigate the effects of oral LEM on QOL and immunological function in cancer patients receiving immunotherapy. Design • The research team designed an open-label, single-armed pilot study. Setting • The study took place at Bio-Thera Clinic, a facility associated with Tokyo Women's Medical University in Tokyo, Japan. Participants • The participants were 10 cancer patients undergoing cancer immunotherapy at Bio-Thera Clinic. Intervention • The participants received either dendritic cell (DC)-based cancer vaccine therapy or CD3-activated T-lymphocyte (CAT) therapy as immunotherapy. They received the immunotherapy only for the first 4 wk of the study, and then oral LEM (1800 mg/d) was added for the next 4 wk. Outcome Measures • Preintervention and at 4 and 8 wk after the start of the study, participants completed a QOL survey, and immunological parameters were measured. Results • Participants' QOL symptom scores increased (ie, worsened) by 5.1 ± 1.7 during the first 4 wk of treatment when they were receiving immunotherapy only, but it decreased (ie, improved) by -2.5 ± 1.6 during the next 4 wk when the immunotherapy was combined with the LEM, P immunotherapy combined with LEM showed that the amount of interferon-γ (IFN-γ) produced in the peripheral blood tended to increase as compared with that during the first 4 wk of immunotherapy only. The rise in IFN-γ was correlated with changes in several regulatory T cells (Tregs) (ie, forkhead box P3 [FOXP3]+/cluster of differentiation 4 [CD4]+ and transforming growth factor beta [TGF-β]). Conclusions • The findings suggest that a combined treatment of LEM and immunotherapy might

    A 73-year-old woman had undergone mastectomy for left breast cancer. One year later, bone metastasis was detected. After 7 years, the patient experienced epigastric discomfort, and gastrointestinal endoscopy showed stenosis of the pylorus and enlarged gastric folds. Stomach cancer was suspected at first, but gastric metastasis of breast cancer was diagnosed on the basis of endoscopic reexamination and computed tomography(CT)images. The patient could not drink water, and therefore, gastrointestinal stenting was performed, which facilitated ingestion to some extent. However, at the same time, an elevated serum carcinoembryonic antigen(CEA)level and jaundice were observed. Therefore, biliary tract stenosis due to carcinomatous peritonitis was diagnosed. We attempted to treat the jaundice with endoscopic retrograde cholangiopancreatography( ERCP)or percutaneous transhepatic cholangiography(PTCD), but the treatment was not successful, and an increase in ascites was noted. Accordingly, gemcitabine was administered as systemic therapy. As a result, ascites decreased and jaundice improved. Patients with gastric metastasis of breast cancer have poor quality of life(QOL)because of difficulties in ingestion or vomiting, and poor prognoses, because of frequent concurrent carcinomatous peritonitis. We experienced a case of gastric metastasis and carcinomatous peritonitis, and were able to improve the patient's QOL by gastrointestinal stenting and gemcitabine administration.

    Social health is important to measure when assessing outcomes in community mental health. Our objective was to validate social health scales using items from two broader commonly used measures that assess mental health outcomes. Participants were 609 adults receiving psychological treatment services. Items were identified from the California Quality of Life (CA-QOL) and Mental Health Statistics Improvement Program (MHSIP) outcome measures by their conceptual correspondence with social health and compared to the Social Functioning Questionnaire (SFQ) using correlational analyses. Pearson correlations for the identified CA-QOL and MSHIP items with the SFQ ranged from .42 to .62, and the identified scale scores produced Pearson correlation coefficients of .56, .70, and, .70 with the SFQ. Concurrent validity with social health was supported for the identified scales. The current inclusion of these assessment tools allows community mental health programs to include social health in their assessments.

    We present a case of polyarticular synovitis following alendronate treatment for osteoporosis. The patient had no evidence of rheumatoid arthritis, pyrophosphate arthropathy, or seronegative/seropositive arthritis. Our main aim in this study is to highlight the potential adverse effects of alendronate and to warn orthopedic surgeons about the possibility of such a side effect that might lead orthopedic surgeons to administer wrong and unnecessary treatments like arthrocentesis. The withdrawal of alendronate is found to be the treatment of choice. Alendronate should be considered as a possible cause of synovitis or polyarthritis in patients treated with this agent in the absence of any other pathology. An association between alendronate and synovitis has rarely been described in the literature. We present a patient who developed polyarticular synovitis after treatment with alendronate and responded to its withdrawal.

    Highlights: {yields} We examine bone metabolism of engineered alendronate attached to Ti surfaces. {yields} Alendronate-immobilized Ti enhances activation of osteoblast differentiation. {yields} Alendronate-immobilized Ti inhibits osteoclast differentiation. {yields} Alendronate-immobilized Ti may be a bioactive implant with dual functions. -- Abstract: The failure of orthopedic and dental implants has been attributed mainly to loosening of the implant from host bone, which may be due to weak bonding of the implant material to bone tissue. 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. Our study suggests that alendronate-immobilized Ti may be a bioactive implant with dual functions to enhance

    The present study assessed the real life therapeutic effects of weekly doses of alendronate in treating a group of osteoporotic patients in Iran. The present historical cohort was conducted on patients who had undergone two or more bone mineral densitometry within an interval of 1.5-2 years in Shariati Hospital bone mineral density department between 2002 and 2010.patients were asked by phone about consumption of alendronate. The mean increase in the BMD values at different sites was calculated. There was a significant increase in the body mass index (BMI) values of both the individuals taking alendronate and the control group (P<0.001). Taking the weekly dosage of the drug was associated with a 7.67% increase in the BMD values at the femoral neck, 8.68% at the total hip, and 3.17% at the lumbar spine. Moreover, our results showed a significant difference between the height decline in the two groups (alendronate taking: 0.7±2.4 vs. control: -0.7±2.6, P<0.001). Comparing the results of the present study with that of previous ones revealed the drug is beneficial in improving bone mineral density in Iranians; as well alendronate is more effective in Iranian postmenopausal women when compared with the Americans.

    The purpose of this study was to clarify the factors affecting the quality of life (QOL) of the elderly home-bound patients. Data were collected from 56 chronically disabled elderly persons (mean age of 76.7 years) who needed a long-term home-based care. They were assessed on QOL, range of activity, functional capacity, and capacity of family care functioning as well as socio-economic condition. The QOL was evaluated by using Philadelphia Geriatric Center Morale Scale (PGC Morale Scale). The activities of daily living (ADL) and handicaps were evaluated by the Barthel index and the ESCROW profile, respectively. The capacity of family care functioning was also recorded according to the "Family Care Scale" developed by Hamamura. As a result, there was a significant difference between PGC Morale Scale score and Barthel index score (P QOL of the home-bound elderly disabled were determined by the motivation, functional capacity, and capacity of family care functioning (P QOL, ADL must be improved, therefore, rehabilitation should be continued to maintain their function after discharging from hospitals and that we should take these factors into consideration, such as living environments and social conditions of the family care. The results also indicate how the patient's independence in the daily life influences social and economic status, and consequently it affects the quality of life.

    . The other half of the implants continued pistoning. Half of the dogs were exposed to alendronate (oral). Results Stabilization of the revision implant was more effective at improving fixation (higher shear strength) than administering alendronate. As expected, the fibrous membrane remained under unstable...... model with controlled motion to evaluate the relative effects of implant motion and bisphosphonate. We implemented our established 8-week experimental revision protocol to obtain a bony and soft tissue setting of revision joint replacement in 16 dogs. At 8 weeks, we had stabilized half of the implants...

    The main goal of therapy for Graves' orbitopathy (GO) is to restore visual function and to improve quality of life (QOL); therefore, the idea of self-assessment of eye changes by the patient has been developed. We developed a validated Polish version of the GO-QOL questionnaire (GO-QOLpl). As an original version we used the English version of GO-QOL, which consists of 15 questions summarised in two subscales. GO-QOLpl was translated and validated in accordance with standard principles for translation of patient-reported outcomes (PRO). GO-QOLpl is a linguistically validated version of the original GO-QOL questionnaire, which is recommended by the European Group of Graves' Orbitopathy (EUGOGO). We strongly support the use of GO-QOLpl for the assessment of QOL among Polish patients with GO in clinical practice.

    Osteomyelitis is a progressive destruction of bones caused by microorganisms. Inadequate or absent treatment increases the risk of bone growth inhibition, fractures, and sepsis. 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 (99m)technetium-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 (99m)technetium-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-bearing animals for all investigated time intervals. Biodistribution studies were also performed after the intravenous administration of the formulation in osteomyelitis-bearing animals. A significant amount of liposomes were taken up by the organs of the mononuclear phagocyte system (liver and spleen). Intense renal excretion was also observed during the entire experiment period. Moreover, the liposome uptake by the infectious focus was

    Full Text Available Abstract Background To identify high-risk patients and provide pharmacological treatment is one of the effective approaches in prevention of osteoporotic fractures. This study investigated the effect of 12-month Alendronate treatment on bone mineral density (BMD and bone turnover biochemical markers in postmenopausal women with one or more non-traumatic fractures, i.e. patients with established osteoporosis. Methods A total of 118 Hong Kong postmenopausal Chinese women aged 50 to 75 with low-energy fracture at distal radius (Colles' fracture were recruited for BMD measurement at lumbar spine and non-dominant hip using Dual-Energy X-ray Absorptiometry (DXA. 47 women with BMD T-score below -2 SD at either side were identified as patients with established osteoporosis and then randomized into Alendronate group (n = 22 and placebo control group (n = 25 for BMD measurement at spine and hip using DXA and distal radius of the non-fracture side by peripheral quantitative computed tomography (pQCT, and bone turnover markers, including bone forming alkaline phosphatase (BALP and bone resorbing urinary Deoxypyridinoline (DPD. All measurements were repeated at 6 and 12 months. Results Alendronate treatment significantly increased BMD, more in weight-bearing skeletons (5.1% at spine and 2.5% at hip than in non-weight bearing skeleton (0.9% at distal radius after 12 months treatment. Spine T-score was significant improved in Alendronate group (p Conclusion 12 months Alendronate treatment was effective to increase BMD at both axial and appendicular skeletons in postmenopausal women with established osteoporosis.

    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

    Alendronate, a nitrogen-containing bisphosphonate, is a potent inhibitor of bone resorption used for the treatment and prevention of osteoporosis. Recent findings suggest that alendronate and other N-containing bisphosphonates inhibit the isoprenoid biosynthesis pathway and interfere with protein prenylation, as a result of reduced geranylgeranyl diphosphate levels. This study identified farnesyl disphosphate synthase as the mevalonate pathway enzyme inhibited by bisphosphonates. HPLC analysis of products from a liver cytosolic extract narrowed the potential targets for alendronate inhibition (IC(50) = 1700 nM) to isopentenyl diphosphate isomerase and farnesyl diphosphate synthase. Recombinant human farnesyl diphosphate synthase was inhibited by alendronate with an IC(50) of 460 nM (following 15 min preincubation). Alendronate did not inhibit isopentenyl diphosphate isomerase or GGPP synthase, partially purified from liver cytosol. Recombinant farnesyl diphosphate synthase was also inhibited by pamidronate (IC(50) = 500 nM) and risedronate (IC(50) = 3.9 nM), negligibly by etidronate (IC50 = 80 microM), and not at all by clodronate. In osteoclasts, alendronate inhibited the incorporation of [(3)H]mevalonolactone into proteins of 18-25 kDa and into nonsaponifiable lipids, including sterols. These findings (i) identify farnesyl diphosphate synthase as the selective target of alendronate in the mevalonate pathway, (ii) show that this enzyme is inhibited by other N-containing bisphosphonates, such as risendronate, but not by clodronate, supporting a different mechanism of action for different bisphosphonates, and (iii) document in purified osteoclasts alendronate inhibition of prenylation and sterol biosynthesis.

    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.

    Sodium alendronate is an effective treatment for osteoporosis, but its oral administration is associated with adverse gastrointestinal effects. The aim of this work was to evaluate gastroresistant sodium alendronate-loaded microparticles prepared by spray-drying using Eudragit S100 or a blend of Eudragit S100/Methocel E4M. Both formulations presented high encapsulation efficiencies, mean diameters below 17 microm, and similar collapsed shape. Dissolution experiments showed good gastro-resistance for the microparticles at pH 1.2. At pH 6.8, the blended microparticles retarded the drug release. In vivo studies showed that the formulations were able to protect the rat stomachs against ulcer formation by sodium alendronate. In conclusion, the microparticles seems to be promising oral carriers for sodium alendronate.

    Aminobisphosphonate aledronate is a compound commonly used clinically for the treatment of osteoporosis and other bone diseases, as a result of it preventing bone resorption. However, in previous years it has also been used to obtain cellular and animal models of a rare genetic disorder termed Mevalonate Kinase Deficiency (MKD). MKD is caused by mutations affecting the mevalonate kinase enzyme, in the cholesterol pathway and alendronate can be used to biochemically mimic the genetic defect as it inhibits farnesyl pyrophosphate synthase in the same pathway. Despite evidence in favor of the inhibition exerted on the mevalonate pathway, there is at least one clinical case of MKD in which alendronate improved not only skeletal and bone fractures, as expected, but also MKD clinical features. Based on this finding, the present study assessed the anti‑inflammatory properties of this aminobisphosphonate in vitro. No anti‑inflammatory effects of alendronate were observed in the in vitro experiments. Since MKD lacks specific treatments, these results may assist scientists and physicians in making the decision as to the most suitable choice of therapeutic compounds for this neglected disease.

    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 statistical...

    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.

    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.

    The purpose of the present study was to precisely compare both the efficacy and abdominal symptom-related quality of life after treatment with daily minodronate and weekly alendronate in patients with primary postmenopausal osteoporosis. The efficacy of the two drugs was assessed based on improvements in a bone turnover marker, back pain, and gastrointestinal symptoms that impair quality of life, which was assessed using the Izumo scale questionnaire. In the minodronate group, there were no significant changes during the treatment period in the specific scores for heartburn, epigastralgia and epigastric fullness, whereas all of the scores were significantly elevated at some time point after drug administration in the alendronate group. Urinary N-telopeptide of type I collagen (uNTX), a bone resorption marker, and bone-specific alkaline phosphatase, a bone formation marker, significantly decreased in both groups, but decreases in uNTX in the minodronate group was observed significantly earlier compared with those in the alendronate group. The back pain scores, which were obtained using a visual analog scale, were significantly reduced in both groups. However, analgesic effects were detected earlier in the minodronate group. In conclusion, compared with weekly alendronate, daily minodronate improved bone turnover and back pain more promptly without causing upper gastrointestinal symptoms.

    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 (pbone turnover only between RG and SG (p=0.074) and AG and OG (p=0.138). All other comparisons showed significant differences (pbone 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.

Upper endoscopy frequency, cancer incidence and mortality was examined in 30,606 alendronate users (female, age 50¿+¿) and 122,424 matched controls......Recent studies have reached conflicting conclusions regarding the risk of esophageal cancer with oral bisphosphonates. Prior studies did not record the number of cancer deaths or endoscopy rates, which could be higher in bisphosphonate users and lead to more cancers being diagnosed at a stage when....... Primary outcomes were esophageal cancer incidence and death due to esophageal cancer. The analysis showed that alendronate users were more likely to have undergone recent upper endoscopy (4.1 vs 1.7%, p¿...

    Nicolau CONTE NETO

    Full Text Available Abstract The main objective of this study was to cause bisphosphonate-related osteonecrosis of the jaws to develop in a rodent model. Adult male Holtzman rats were assigned to one of two experimental groups to receive alendronate (AL; 1 mg/kg/week; n = 6 or saline solution (CTL; n = 6. After 60 days of drug therapy, all animals were subjected to first lower molar extraction, and 28 days later, animals were euthanized. All rats treated with alendronate developed osteonecrosis, presenting as ulcers and necrotic bone, associated with a significant infection process, especially at the inter-alveolar septum area and crestal regions. The degree of vascularization, the levels of C-telopeptide cross-linked collagen type I and bone-specific alkaline phosphatase, as well as the bone volume were significantly reduced in these animals. Furthermore, on radiographic analysis, animals treated with alendronate presented evident sclerosis of the lamina dura of the lower first molar alveolar socket associated with decreased radiographic density in this area. These findings indicate that the protocol developed in the present study opens new perspectives and could be a good starting model for future property design.

    This study aimed to demonstrate the validity, reliability and responsiveness of a new disease-specific quality of life (QoL) questionnaire for children and adults with thalassaemia major, the Transfusion-dependent QoL questionnaire (TranQol). 106 participants (51 adults and 55 children) were recruited from six North American thalassaemia treatment centres with a mean age of 20·7 years (standard deviation [SD] 9, range 7-51 years). The mean total TranQol score was 71 (SD 17, 32-97) on a scale of 0-100. Patients with co-morbidities had significantly lower scores (63 vs. 75, P = 0·001). TranQol scores showed substantial agreement (P < 0·001) with the Health Utilities Index Mark 3 (all patients, r = 0·65), the Pediatric QoL (children, r = 0·77) and the Short Form (36) physical (adults, r = 0·69) and mental summary scores (r = 0·76). In the subgroup who rated their QoL as better, there was a 4·0 point (SD 9·0) improvement in TranQol scores, from baseline of 67·1-71·1 one week later (P = 0·008). Test-retest reliability was excellent (intra-class correlation coefficient, 0·93). The TranQol was valid, with acceptable correlation for all administered measures and was reliable and responsive to change. The TranQol can be incorporated into future studies of thalassaemia major.

    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.

    The time trade-off (TTO) valuation technique is widely used to determine utility values of health outcomes to inform quality-adjusted life-year (QALY) calculations for use in economic evaluation. Protocols for implementing TTO vary in aspects such as the trade-off framework, iteration procedure and its administration model and method, training of respondents and interviewers, and quality control of data collection. The most widely studied and utilized TTO valuation protocols are the Measurement and Valuation of Health (MVH) protocol, the Paris protocol and the EuroQol Valuation Technology (EQ-VT) protocol, all developed by members of the EuroQol Group. The MVH protocol and its successor, the Paris protocol, were developed for valuation of EQ-5D-3L health states. Both protocols were designed for a trained interviewer to elicit preferences from a respondent using the conventional TTO framework with a fixed time horizon of 10 years and an iteration procedure combining bisection and titration. Developed for valuation of EQ-5D-5L health states, the EQ-VT protocol adopted a composite TTO framework and made use of computer technology to facilitate data collection. Training and monitoring of interviewers and respondents is a pivotal component of the EQ-VT protocol. Research is underway aiming to further improve the EuroQol protocols, which form an important basis for the current practice of health technology assessment in many countries.

    Full Text Available The aim of this study was to compare the effect of alendronate and calcitonin treatments on bone mineral density (BMD and quality of life of women with postmenopausal osteoporosis. One hundred ninety-three patients were randomly assigned to two groups: 93 patients received daily doses of 10 mg alendronate and calcium 1000 mg, and 98 patients used intranasal salmon calcitonin (sCt at a dosage of 200 IU/day and they also received daily doses of 1000 mg calcium supplements. DXA was used for the measurement of BMD of the lumbar spine and proximal femur before and after the study period. SF-36 was used as a measure of health-related quality of life. At the end of the treatment, ALN produced significant increases in BMD at the lumbar spine (p< 0.001, femur neck (p<0.05, trochanteric region (p<0.001 and at the Ward triangle (p<0.05. In contrast, intranasal sCt treatment resulted in a significant bone loss in the femur neck (p<0.01 and Ward triangle (p<0.05, and only a significant increase in BMD of the lumbar spine was observed with calcitonin treatment(p< 0.05. Quality of life as assessed by SF-36 improved significantly in both groups(p<0.05. In conclusion, alendronate seemed to be more effective than calcitonin, increasing both spinal and femoral BMD, for the treatment of postmenopausal osteoporosis. Both treatments were found to be effective for the improvement of quality of life.

    Aim: Chondrosarcoma is a malignant primary bone tumor that responds poorly to both chemotherapy and radiation therapy. The aim of the present study was to investigate the effect of alendronate, a bisphosphonate, on the invasion and migration of human chondrosarcoma cells (JJ012). Methods: JJ012 cells were treated with alendronate of various concentrations up to 100 μmol/L for a speci-fied period, and then gelatin zymography and matrigel invasion assay was per-formed to study the effects of alendronate on matrix metalloproteinase (MMP)-2 activity and the invasion ability of JJ012 cells, respectively. Results: Our data showed that alendronate exerted a dose- and time-dependent inhibitory effect on the invasion and migration of JJ012 cells. Furthermore, gelatin zymography and RT-PCR showed that alendronate treatment decreased the activity and mRNA levels of MMP-2 in a concentration-dependent manner. Conclusion: Our find-ings suggest that alendronate may reduce MMP-2 secretion at the transcriptional and translational levels, and inhibit the invasion of chondrosarcoma cell. Therefore,alendronate may be a potential candidate for the systemic therapy of chondro-sarcomas, as well as other malignant diseases.

    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.

    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)

    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.

    Sodium alendronate, an antiresorptive drug, primarily used in the treatment of osteoporosis was encapsulated in blended microparticles composed of Eudragit S100 and Methocel K15M. The micropowder obtained by spray-drying technique was characterized in terms of its morphology, particle size, encapsulation efficiency and in vitro drug release. In vivo studies were carried out in order to evaluate the pharmacodynamic effect and the ulcerogenic activity of sodium alendronate-loaded microparticles after oral administration in rats. Drug encapsulation efficiency was close to 80% and particle mean diameter of 13.8 microm. SEM analysis showed spherical collapsed shape particles with smooth surface. At pH 1.2, in vitro experiments showed that <10% of the drug was released from the microparticles. At pH 6.8, the microparticles were able to prolong the sodium alendronate release for 12h. In vivo experiments carried out in ovariectomized rats showed bone mineral density significantly higher for the sodium alendronate-loaded microparticles than for the negative control groups. Furthermore, the microencapsulation of the drug showed a significant reduction in the ulcerative lesion index. In conclusion, the blended microparticles are excellent oral carriers for sodium alendronate since they were able to maintain the drug antiresorptive effect and to reduce the gastrointestinal drug toxicity.

    Glucocorticoid-induced osteoporosis (GIOP) is a serious problem for patients with rheumatic diseases requiring long-term glucocorticoid treatment. Alendronate, a bisphosphonate, has been recommended in the prevention of GIOP. However, the efficacy and safety of alendronate in preventing GIOP remains controversial. We performed a meta-analysis to investigate the efficacy and safety of alendronate in preventing GIOP in patients with rheumatic diseases.We retrieved randomized controlled trials from PubMed, EMBASE, and the Cochrane Library. Two reviewers extracted the data and evaluated the risk of bias and quality of the evidence. We calculated the risk ratio (RR) with a 95% confidence interval (CI) for dichotomous outcomes, and the mean difference (MD) with a 95% CI for continuous outcomes using Review Manager, version 5.3.A total of 339 studies were found, and 9 studies (1134 patients) were included. Alendronate was not able to reduce the incidence of vertebral fractures (RR = 0.63, 95% CI: 0.10-4.04, P = 0.62) and nonvertebral fractures (RR = 0.40, 95% CI: 0.15-1.12, P = 0.08). Alendronate significantly increased the percent change in bone mineral density (BMD) at the lumbar spine (MD = 3.66, 95% CI: 2.58-4.74, P power.

    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 (T{sub 0}) and at 3 months ({sub 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 T{sub 3mo}, 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 T{sub 0} was better in those alive than in those deceased at T{sub 3mo}, 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.)

    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.

    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.

    An autoimmune disease of rheumatoid arthritis (RA) causes severe inflammation on the synovial membrane, which results in the destruction of articular cartilage and bone. Here, Tocilizumab (TCZ) - Alendronate (ALD) conjugate is synthesized for the early intervention of RA. A humanized monoclonal antibody of TCZ shows an immunosuppressive effect, targeting interleukin-6 (IL-6) receptor in the RA pathogenesis. ALD is an anti-inflammatory bisphosphonate drug which can bind to the exposed bone surface. ALD is conjugated selectively to N-glycan on Fc region of TCZ using a chemical linker of 3-(2-pyridyldithio) propionyl hydrazide (PDPH) - poly(ethylene glycol) - N-hydroxysuccinimide (PDPH-PEG-NHS). The successful synthesis of TCZ-ALD conjugate is corroborated by 1H NMR, the purpald assay, mass spectrometry (MS), and high performance liquid chromatography (HPLC). In vitro binding affinity and cell viability tests confirmed the biological activity of TCZ-ALD conjugate. Furthermore, in vivo efficacy of TCZ-ALD conjugate is confirmed by micro computed tomography (CT), histological, and western blot analyses for the treatment of RA.

    Therapy with bisphosphonates, including alendronate (ALN), is considered a safe and effective treatment for osteoporosis. However, recent studies have reported an unexpected increase in serious atrial fibrillation (AF) in patients treated with bisphosphonates. The mechanism that explains this side effect remains unknown. Since AF is associated with an altered sarcoendoplasmic reticulum calcium load, we studied how ALN affects cardiomyocyte calcium homeostasis and protein isoprenylation in vitro. Acute and long-term (48h) treatment of atrial and ventricular cardiomyocytes with ALN (10(-8)-10(-6)M) was performed. Changes in calcium dynamics were determined by both fluorescence measurement of cytosolic free Ca(2+) concentration and western blot analysis of calcium-regulating proteins. Finally, effect of ALN on protein farnesylation was also identified. In both atrial and ventricular cardiomyocytes, ALN treatment delayed and diminished calcium responses to caffeine. Only in atrial cells, long-term exposure to ALN-induced transitory calcium oscillations and led to the development of oscillatory component in calcium responses to caffeine. Changes in calcium dynamics were accompanied by changes in expression of proteins controlling sarcoendoplasmic reticulum calcium. In contrast, ALN minimally affected protein isoprenylation in these cells. In summary, treatment of atrial cardiomyocytes with ALN-induced abnormalities in calcium dynamics consistent with induction of a self-stimulatory, pacemaker-like behavior, which may contribute to the development of cardiac side effects associated with these drugs.

    Summary Bisphosphonates have been commonly used in the treatment of osteoporosis, demonstrating its efficacy in fracture risk reduction. However, even if are generally safe and well tolerated, concerns have emerged about atypical fractures related to its prolonged use. Although atypical femoral fracture are more common, case reports demonstrated that even other skeletal areas can be involved by unusual pattern of fracture. We report a atypical acetabular periprosthetic fracture in a 83-year-old female patient after prolonged alendronate treatment for osteoporosis and isolated acetabular revision surgery. The patient underwent to clinical, bioumoral and radiological evaluation and all the history cases were fully reported. We believe this periprosthetic fracture, according to the available data, may have similar underlying pathology to atypical femoral fractures. Awareness of symptoms, in addition to a regular radiographic survey may facilitate early diagnosis and possible prevention of spontaneous periprosthetic fractures, in patients receiving bisphosphonate therapy beyond 5 years. The treatment of this atypical periprosthetic fracture should include both surgical than pharmacological therapy to obtained bone healing. PMID:28228784

    Full Text Available In this case report, the efficacy of 12-month alendronate and cholecalciferol combination therapy for the treatment of osteoporosis in two male patients with chronic viral hepatitis aged above 60 years who were on antiviral treatment was evaluated. The patients were diagnosed with osteoporosis via dual energy x-ray absorptiometry while receiving 245 mg tenofovir disoproxil fumarate once daily and started on alendronate and cholecalciferol combination (70 mg/2800 IU. Baseline T-scores of the two patients were -2.6 and -4.9, respectively. Baseline bone mineral density (BMD and 25(OHD (ng/ml values were compared with post-treatment values. Regarding the first case, following treatment, lumbar, femoral neck and total hip BMD values were improved by 1.9%, 5.2% and 13.8%, respectively. In the second case, L1-L4 lumbar, femoral neck and total hip BMD values were improved by 23.2%, 25.9% and 14.8%, respectively. However, when pre- and posttreatment 25(OHD levels were compared, a decrease was observed in both patients. In conclusion, 12-month treatment with alendronate and cholecalciferol combination improved BMD values, in patients with chronic viral hepatitis who were on antiviral therapy. Considering that tenofovir therapy effects vitamin D metabolism independently in these patients, it is necessary to control 25(OHD levels in a regular basis and to support the patient with adequate vitamin D supplementation, in order to optimize serum vitamin D levels and prevent from vitamin D insufficiency.

    Full Text Available Purpose: To describe the definition of quality of life (QoL and identify the most appropriate tool for QoL assessment used in patients with TBI.Method: Searching was conducted from PubMed, CINAHL, EBSCO, and ProQuest during 2000-2011. A total of 33 studies were analyzed for this review consisting of 9 review studies, 2 intervention studies, and 22 descriptive studies.Result: Two important definitions of QoL were used in studies related to TBI namely achievement and subjective well-being. Although varieties of generic measurements have been used to measure QoL in TBI patients, there was a lack of TBI-specific Health-related Quality of Life (HRQoL instrument. Despite the different approach and time measured either short or long outcomes, appropriate domains of QoL tool seem essential particularly among those with moderate and severe TBI.Conclusion: QoL is a wide concept which can be defined in several dimensions. The QOLIBRI as a new disease-specific QoL measurement in TBI seems a feasible and valid approach for the assessment of QoL in TBI. However, the application across cultural remains a challenge and needs a validation.

    The importance of quality of life (QOL) measurement among breast cancer survivors (BCS) is well-recognized by researchers and clinicians. With data from 427 rural BCS, the authors used a combination of clinical expertise and statistical analysis to revise a 48-item measure of QOL specific to BCS. The revised 15-item measure showed adequate psychometric properties and provides the basis for a brief yet comprehensive multidimensional measure of QOL applicable to most BCS. Future work includes fine-tuning the measurement model and examining its generalizability among non-rural BCS.

    A combined therapy with the strongly antiresorptive Alendronate and the pleiotropically acting D-hormone analogue Alfacalcidol may have additive effects on bone quality, falls and fracture risk in established osteoporosis. The aim of this study (Alfacalcidol Alendronate Combined-AAC) was to compare the efficacy and safety of a combined parallel therapy with Alendronate and Alfacalcidol to the treatment with either Alendronate in combination with plain vitamin D or Alfacalcidol alone in patients with established postmenopausal or male osteoporosis. Ninety patients were included as matched triplets to receive randomly either 1 microg Alfacalcidol daily + 500 mg calcium (group A, n = 30) or 70 mg Alendronate weekly + 1,000 mg calcium + 1,000 IU vitamin D daily (group B, n = 30) or 1 microg Alfacalcidol daily + 70 mg Alendronate weekly + 500 mg calcium daily (group C, n = 30). Patients were recruited in one centre and were followed up for 24 months. Analysis was intention-to-treat and the primary outcome was lumbar spine and total hip bone mineral density (measured observer blind). BMD was measured at the lumbar spine and at the proximal femur with dual energy X-ray absorptiometry (LUNAR Prodigy, GE, USA) at the beginning and after 12 and 24 months. During the 2-year-study we observed descriptively significant increases at the lumbar spine of 3.0% in group A compared to baseline, of 5.4% in group B and of 9.6% in group C, respectively. The superiority of the Alendronate + Alfacalcidol treatment group over Alfacalcidol alone and over Alendronate + vitamin D was of more than large rele-vance (both tests: MW > 0.71; CI-LB > 0.64; P vitamin D, but not versus Alfacalcidol alone. We found 80% of the patients in the Alendronate + Alfacalcidol group free from back pain at month 24, compared to 30% in the Alendronate + vitamin D and 43% in the Alfacalcidol monotherapy group. The superiority is relevant (both tests: MW > 0.64; CI-LB > 0.56; P back pain over either Alendronate in

    In economic evaluation of healthcare programmes both QOL and productivity of patients are aspects to be studied. Normally, the former is part of the measurement of the effectiveness of the programme and the latter is part of the measurement of its costs. In this paper we highlight the relationship between QOL and productivity. Two aspects are discussed: (i) the relationship between perceived productivity and health-state valuations; and (ii) the observed relationship between productivity and QOL. The first aspect relates to the fact that in health-state valuations, respondents may consider income changes and ability to work. While this may have important methodological and practical implications, little empirical evidence exists in this area. The second aspect relates to the fact that the observed productivity of individuals is expected to be related to their health-related QOL. Worse health states are expected to be associated with lower productivity. Again, empirical investigation is lacking; however, this relationship may prove important, for instance in modelling productivity costs with use of information on QOL. This paper explores these relationships between productivity and QOL to stimulate debate and research in this area.

    Khaled Mohamed Hosny

    Full Text Available 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.

    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.

    The objective of this study was to evaluate the effect of physical activity from the "Menopause in Form" program on physical aptitude, functional capacity, corporal balance and QoL among elderly women. In addition, correlations among these variables were examined. The present work was a longitudinal study that was quasi-experimental and correlational. A total of 323 elderly women (age: 69.0±5.53 years) participated in this study. Subjects were non-institutionalized, post-menopausal individuals residing at the Elderly Care Center in Belém Municipality (Pará, Brazil) and practiced one activity (i.e., dancing or walking) over a 10-month period. The assessment protocols used were the following: the Fullerton functional fitness test battery (physical aptitude); the activities of daily living (ADL) indices (functional capacity); the Tinetti-scale (corporal balance); and the WHOQOL-OLD questionnaire (QoL). The adopted significance level was p<0.05. Results from the Wilcoxon test demonstrated significant differences for the post-test assessment of functional capacity (Δ%=5.63%; p=0.0001) and general QoL (Δ%=9.19%; p=0.001). These results suggest that the physical activities employed during the "Menopause in Form" program resulted in significant improvements in the functional capacity and QoL of post-menopausal elderly women.

    The wide use of cosmetics and their perceived benefits upon well-being imply objective descriptions of their effects upon the different dimensions contributing to the quality of life (QoL). Such a goal pleas for using relevant and validated scientific instruments with robust measurement methods. This paper discusses the interest of the new validated questionnaire BeautyQoL specifically designed to assess the effect of cosmetic products on physical appearance and QoL. After conducting a review of skin appearance and QoL, three phases of the international codevelopment have been carried out in the following sequence: semi-directed interviews (Phase 1), acceptability study (Phase 2), and validation study (Phase 3). Data collection and validation process have been carried out in 16 languages. This review confirms that QoL instruments developed in dermatology are not suitable to assess cosmetic products, mainly because of their lack of sensitivity. General acceptability of BeautyQol was very good. Forty-two questions have been structured in five dimensions that explained 76.7% of the total variance: Social Life, Self-confidence, Mood, Vitality, and Attractiveness. Cronbach's alpha coefficients are between 0.932 and 0.978, confirming the good internal consistency of the results. The BeautyQol questionnaire is the first international instrument specific to cosmetic products and physical appearance that has been validated in 16 languages and could be used in a number of clinical trials and descriptive studies to demonstrate the added value of these products on the QoL.

    Full Text Available Abstract Background Avascular necrosis of bone (osteonecrosis can cause structural failure and subsequent deformation, leading to joint dysfunction and pain. Structural failure is the result of resorption of necrotic bone during revascularization, before new bone has formed or consolidated enough for loadbearing. Bone resorption can be reduced by bisphosphonates. If resorption of the necrotic bone could be reduced during the revascularization phase until sufficient new bone has formed, it would appear that structural failure could be avoided. Methods To test whether resorption of necrotic bone can be prevented, structural grafts were subjected to new bone ingrowth during systemic bisphosphonate treatment in a rat model. Results In rats treated with alendronate the necrotic bone was not resorbed, whereas it was almost entirely resorbed in the controls. Conclusion Systemic alendronate treatment prevents resorption of necrotic bone during revascularization. In patients with osteonecrosis, bisphosphonates may therefore prevent collapse of the necrotic bone.

    We translated and adapted the English RC-QOL (rotator cuff quality of life) questionnaire into Italian and performed reliability and validity evaluations of the Italian RC-QOL version in patients with rotator cuff tears. The RC-QOL English version was translated into Italian by a bilingual orthopaedic surgeon. The back translation of the Italian version into English was performed by another bilingual orthopaedic surgeon. The original version was compared with the back translation. The RC-QOL questionnaire was then administered to 22 subjects (range 45-74 years) with a diagnosis of rotator cuff tears. For test-retest evaluation, the 22 patients were asked to complete the questionnaire at first examination, and 30 min following the end of this examination. The intraclass correlation coefficient for the 22 patients was 0.94 (95% CI = 0.85-0.98), indicating a high reliability. There were no significant differences between the scores immediately after the consultation and 30 min later. The Italian and the English versions of the RC-QOL questionnaire evaluate the same aspects of clinical severity in patients with rotator cuff tears.

    The integration of bone implants within native bone tissue depends on periprosthetic bone quality, which is severely decreased in osteoporotic patients. In this work, we have synthesized bone-like hydroxyapatite nanocrystals (nHA) using an acid-base neutralization reaction and analysed their physicochemical properties. Subsequently, we have functionalized the nHA with alendronate (nHAALE), a well-known bisphosphonate drug used for the treatment of osteoporosis. An in vitro osteoclastogenesis test was carried out to evaluate the effect of nHAALE on the formation of osteoclast-like cells from monocytic precursor cells (i.e. RAW264.7 cell line) showing that nHAALE significantly promoted apoptosis of osteoclast-like cells. Subsequently, nHA and nHAALE were deposited on titanium disks using electrospray deposition (ESD), for which characterisation of the deposited coatings confirmed the presence of alendronate in nHAALE coatings with nanoscale thickness of about 700 nm. These results indicate that alendronate linked to hydroxyapatite nanocrystals has therapeutic potential and nHAALE can be considered as an appealing coating constituent material for orthopaedic and oral implants for application in osteoporotic patients.

    Full Text Available The aim of this study was to compare the effect of alendronate and calcitonin treatments on bone mineral density (BMD in men with idiopathic osteoporosis. After performing a detailed clinical and laboratory assessment in order to eliminate secondary factors that can lead to osteoporosis, fifty-two men with idiopathic osteoporosis were randomly assigned to two groups: 28 patients in the first group received intranasal salmon calcitonin at a dosage of 200 IU/ day and they also received daily doses of 1000 mg calcium supplements. Twenty-four patients in the second group used 10 mg alendronate/day and 1000 mg calcium/day. DXA was used for the measurement of BMD of the lumbar spine and proximal femur before and after the study period. At the end of the treatment, alendronate produced significant increases in BMD at the lumbar spine (p0.05. When the groups were compared with each other, a significant increase in lumbar BMD was obtained in favor of alendronate treatment (p<0.05. In conclusion, alendronate seemed to be more effective than calcitonin, increasing both spinal and femoral BMD, for the treatment of idiopathic male osteoporosis.

    Full Text Available Aim: The aim of this study was to examine the effect of alendronate 70 mg weekly on knee symptoms in elderly women with osteoporosis and knee OA coexistence. Material and Methods: Elderly women who diagnosed as osteoporosis between 60-75 years old, underwent radiography of the knee if they reported symptoms of knee OA. Radiographs were read for Kellgren and Lawrence grade and individual features of OA. Osteoporotic patients with Knee OA treated with 70 mg alendronate once weekly for one year. Knee symptoms were assessed by interview before the treatment and 6 and 12 months after the treatment, and knee pain severity was evaluated using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC, Lequense index, VAS at rest and at movement. Results: Alendronate 70 mg once weekly use was associated with less severity of knee pain as assessed by WOMAC scores, Lequense index, VAS at rest and at movement at 6th and 12th month assessments. Conclusion: This current study has shown that Alendronate 70 mg once weekly use was associated with less severity of knee symptoms in elderly women with osteoporosis and knee OA coexistence. Additional long-term randomised, placebo controlled clinical trials are needed to confirm this effect of weekly Alendronate. (From the World of Osteoporosis 2010;16:17-21

    Osteoporosis has become an important health problem in postmenopausal Chinese women. Bisphosphonates currently are the preferred therapy for treating osteoporosis. However, the use of daily regimen of alendronate in women at risk for osteoporosis has been relatively low in China because of its dosing inconvenience. To determine the efficacy and tolerability of once-weekly alendronate 70 mg in Chinese, a multicenter, randomized, double blind, placebo controlled study was performed in China. Five hundred and sixty postmenopausal women (osteoporosis were randomly assigned to receive either alendronate 70 mg or placebo once-weekly for 12 months. All women received calcium 500 mg daily and vitamin D 200 IU daily. A significant increase in lumbar spine BMD was already evident at 6 months of alendronate treatment (P or =0% and > or =3% BMD increase in lumbar spine was significantly greater in women with alendronate than placebo (P osteoporosis in Chinese women.

    Health-related quality of life (HRQOL) estimates can play an important role in patient care by providing information about the patient's perception of impairment and disability and the degree to which the patient tolerates disease manifestations. The 15-item myasthenia gravis quality of life scale (MG-QOL15) is an HRQOL evaluative instrument specific to patients with myasthenia gravis (MG) that was designed to be easy to administer and interpret. In this multicenter study we demonstrate the construct validity of the MG-QOL15 in the practice setting. To assess the construct validity, score distributions were examined for test items in different MG patient groups that represent the clinical spectrum of the disease. For example, patients in remission more frequently scored test items as normal than did patients in other groups. Patients with lower (better) MG composite scores also more frequently scored items as normal than did patients with higher (worse) scores. There was also appropriate correlation between the MG-QOL15 and the other MG-specific scales studied. The study findings shed light on what troubles MG patients. The MG-QOL15 has construct validity in the clinical practice setting and represents an efficient and valuable tool for assessing HRQOL for patients with MG.

    Full Text Available Sarcopenia, or age-related muscle loss is emerging as a major public health concern. A reduced quality of life (QoL due to impaired physical performance associated with this disease has been evidenced in these individuals. Generic instruments, such as Short Form 36 questionnaire (SF-36, do not accurately assess the impact of sarcopenia on QoL. SarQol (Sarcopenia Quality of Life questionnaire, was the first disease-specific questionnaire addressing quality of life in patients with sarcopenia and has been recently designed for providing a global picture on quality of life in community-dwelling elderly subjects aged 65 years and older. Our aim was the translation and cultural adaptation of the original SarQol, to finally obtain a highly reliable instrument for the assessment of the quality of life of Romanian patients, affected by sarcopenia. We followed the recommended process, the international protocol of translation. The pretest process involved 20 subjects (10 sarcopenic and 10 non sarcopenic with different educational and socioeconomic backgrounds who were asked to complete the questionnaire. Feedbacks were requested from all subjects regarding the clearness of questions, difficulties in completing the test or understanding the meaning of questions. Using the recommended best practice protocol for translation, the pre-final version is comparable with the original instrument in terms of content and accuracy. After the validation of psychometric properties, it should be a useful tool to assess Quality of Life and sarcopenia among elderly romanian patients.

    Full Text Available Abstract Background Metastatic prostate cancer is associated with a high morbidity and mortality but the spreading mechanisms are still poorly understood. The aminobisphosphonate alendronate, used to reduce bone loss, has also been shown to inhibit the invasion and migration of prostate cancer cells in vitro. We used a modified orthotopic PC-3 nude mouse tumor model of human prostate cancer to study whether alendronate affects prostate tumor growth and metastasis. Methods PC-3 cells (5 × 105 were implanted in the prostates of nude mice and the mice were treated with alendronate (0.5 mg/kg/day in PBS, s.c. or vehicle for 4 weeks. After sacrifice, the sizes of tumor-bearing prostates were measured and the tumors and prostate-draining regional iliac and sacral lymph nodes were excised for studies on markers of proliferation, apoptosis, angiogenesis and lymphangiogenesis, using histomorphometry and immunohistochemistry. Results Tumor occurrence in the prostate was 73% in the alendronate-treated group and 81% in the control group. Mean tumor size (218 mm3, range: 96–485 mm3, n = 11 in the alendronate-treated mice was 41% of that in the control mice (513 mm3, range: 209–1350 mm3, n = 13 (p p p p Conclusion Our results demonstrate that alendronate treatment opposes growth of orthotopic PC-3 tumors and decreases tumor metastasis to prostate-draining lymph nodes. This effect could be at least partly explained by decreased angiogenesis and increased apoptosis. The results suggest that bisphosphonates have anti-tumoral and anti-invasive effects on primary prostate cancer.

    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.

    Joop P W van den Bergh

    Full Text Available INTRODUCTION: An increasing number of generic alendronate formulations have become available. Although expected to have the same tolerability and efficacy, head-to head comparison of generic and brand alendronate was never performed. Therefore, we compared the tolerability and efficacy of generic and brand alendronate. METHODS: In a randomized double-blinded single centre cross-over study in 37 postmenopausal women (mean age 65.4±6.4 years with osteoporosis were treated with generic and branded alendronate during 24 (2x12 weeks. Tolerance was evaluated by the Gastro intestinal Symptom Rating Scale (GSRS and self-reported side effects. Efficacy was assessed by serum bone turnover markers, carboxy terminal telopeptide (CTX and procollagen type I N-terminal propeptide (PINP. No wash out period was allowed (ethical reasons. Because of possible carry over effect only data of the first 12 weeks were analyzed using linear mixed models. RESULTS: There were no significant differences in overall tolerance (GSRS between treatment groups. However, for subscale abdominal pain, patients using generic had a significantly higher mean GSRS score at week 4 (estimated mean difference (B: 0.40; 95%CI: 0.05 to 0.74, p = 0.024. The level of bone turnover markers significantly decreased over 12 weeks of follow-up for generic and branded alendronate (p < 0.001. Mean level of CTX was significantly lower with branded at week 4 (B: 121.3; 95%CI: 52.0 to 190.5, but not at week 12 (B: 53.6; 95%CI:-3.7 to 110.9. No significant differences were found for PINP at week 4 or 12. CONCLUSIONS: Bone turnover markers were significantly reduced with branded and generic alendronate. With branded, CTX was significantly lower at 4 weeks. Generic caused significantly higher abdominal pain scores in the first 4 weeks of treatment. Therefore, generic alendronate may not have the same tolerability and efficacy as branded alendronate in the first weeks after starting treatment in patients

    Objective Research has established that human immunodeficiency virus (HIV) causes hearing loss. Studies have yet to evaluate the impact on quality of life (QOL). This project evaluates the effect of hearing loss on QOL by HIV status. Methods The study participants were from the Multicenter AIDS Cohort Study (MACS) and the Women's Interagency HIV study (WIHS). A total of 248 men and 127 women participated. Pure-tone air conduction thresholds were collected for each ear at frequencies from 250 through 8000 Hz. Pure-tone averages (PTAs) for each ear were calculated as the mean of air conduction thresholds in low frequencies (i.e., 250, 500, 1000 and 2000 Hz) and high frequencies (i.e., 3000, 4000, 6000 and 8000 Hz). QOL data were gathered with the Short Form 36 Health Survey and Medical Outcome Study (MOS)-HIV instrument in the MACS and WIHS, respectively. A median regression analysis was performed to test the association of PTAs with QOL by HIV status. Results There was no significant association between hearing loss and QOL scores at low and high pure tone averages in HIV positive and negative individuals. HIV status, HIV biomarkers and treatment did not change the lack of association of low and high pure tone averages with poorer QOL. Conclusion Although we did not find a statistically significant association of hearing loss with QOL by HIV status, testing for hearing loss with aging and recommending treatment may offset any presumed later life decline in QOL.

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.

    The quality of life is subjective experience which involves in somatic, mental, social, and general feelings.In the clinical research, we can see many interventions to treat depression, but many researchers play close attentions to the effecacy of invevtions. We think we should care more about the improvement of QOL in the patients. As the Evaluating indicator of clinical effect on the depression, the QOL scale should be extensive used in the clinical research in the future.%抑郁症患者的生活质量是一个主观的、动态的概念,涉及躯体、精神、心理、社会及总体感受等多个方面,对生活质量(QOL)的研究已经越来越受到社会的关注,目前临床采取众多干预措施治疗抑郁症,在关注干预措施治疗抑郁症有效性、痊愈率的同时,我们应该更加关注治疗手段是否能够提高患者的生活质量.QOL作为评价抑郁症临床疗效的指标应该在临床上不可或缺,应该得到广泛应用.

    Recent research has employed different analytical techniques to estimate the impact of the various long-term complications of type 2 diabetes on health-related utility and health status. However, limited patient numbers or lack of variety of patient experience has limited their power to discriminate between separate complications and grades of severity. In this study alternative statistical model forms were compared to investigate the influence of various factors on self-assessed health status and calculated utility scores, including the presence and severity of complications, and type of diabetes therapy. Responses to the EuroQol EQ-5D questionnaire from 4641 patients with type 2 diabetes in 5 European countries were analysed. Simple multiple regression analysis was used to model both visual analogue scale (VAS) scores and time trade-off index scores (TTO). Also, two complex models were developed for TTO analysis using a structure suggested by the EuroQol calculation algorithm. Both VAS and TTO models achieved greater explanatory power than in earlier studies. Relative weightings for individual complications differed between VAS and TTO scales, reflecting the strong influence of loss of mobility and severe pain in the EuroQol algorithm. Insulin-based therapy was uniformly associated with a detrimental effect equivalent to an additional moderate complication. Evidence was found that TTO values are not responsive in cases where 3 or more multiple complications are present, and therefore may underestimate utility loss for patients most adversely affected by complex chronic diseases like diabetes.

    Obinutuzumab recently received accelerated approval from the US Food and Drug Administration with breakthrough therapy designation for use in combination with chlorambucil in patients with untreated chronic lymphocytic leukemia (CLL). Obinutuzumab is a CD20 targeting fully humanized, type II, IgG1 antibody. CD20 is weakly expressed on the surface of CLL cells but has been demonstrated to be an effective in vivo target as shown by the activity observed with the use of rituximab and ofatumomab.2-4 Obinutuzumab binds selectively to the extracellular domain of CD20 with reduced internalization and its structural modifications explain its enhanced effectiveness. The antibody is modified in the hinge region which allows for more potent direct cytotoxicity. More importantly, afucosylation in the Fc region allows for enhanced antibody dependent cellular cytotoxicity (ADCC) through robust engagement of Fc-gamma receptor type III on effector cells. Together, these modifications translate into a higher efficacy compared with rituximab both in preclinical and clinical studies.

    The purpose of this study was to evaluate the delivery of alendronate, calcitonin, and osteoprotegerin (OPG) through human dentin by both diffusion and iontophoresis for the potential treatment of invasive cervical resorption. Radiolabeled alendronate, calcitonin, and OPG were added to the top of a split chamber device that contained 1-mm thick dentin disks devoid of a smear layer. Transdentinal movement of medicaments by either random diffusion or application of an iontophoretic current was measured by analysis of gamma emission of effluent fractions. In addition, calcitonin delivery was evaluated at differing magnitudes of current (0-4 mA) by using the aforementioned chamber. Diffusion of all 3 medicaments was minimal. In contrast, the application of a 3-mA iontophoretic gradient significantly increased delivery for all 3 compounds at 10-, 20-, and 30-minute intervals. In addition, a linear increase in permeability was seen for calcitonin as milliamperes were increased from 0 to 4 (r = 0.947), with more than a 100-fold increase in delivery observed with iontophoresis. Delivery of the tested medicaments by using iontophoresis might prove to be a useful technique for treatment of invasive cervical resorption.

    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.

    The purpose of this study was to examine the psychometric properties of the Chinese version of Cerebral Palsy Quality of Life for Children (CP QOL-Child) questionnaire. We performed forward (into Chinese) and backward translation of the CP QOL-Child for: (1) the primary caregiver form (for parents of children with CP aged 4-12 years); and (2) the child self-report form (for children with cerebral palsy aged 9-12 years). Psychometric properties assessed included test-retest reliability, internal consistency, item discrimination, construct validity, and concordance between the forms of questionnaire. The Chinese CP QOL-Child was completed by 145 caregivers and 44 children. Excellent test-retest reliability and internal consistency were obtained. Item discrimination analysis revealed a majority of the items have moderate to good discriminating power. Confirmatory factor analysis demonstrated distinguishable domain structure as on the original English version. Significant associations were found between lower QOL and more severe motor disability. Consistent with the English version, the highest correlation between the primary caregiver and child forms on QOL was in the domain of functioning. Results of this study indicate that the Chinese CP QOL-Child appears to be valid for use in Mandarin-Chinese speaking children with cerebral palsy.

  1. The Bone Resorption Inhibitors Odanacatib and Alendronate Affect Post-Osteoclastic Events Differently in Ovariectomized Rabbits

    2014-01-01

    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...... 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...

    2015-01-01

    Full Text Available Biphasic calcium phosphate (BCP scaffolds have been widely used in orthopedic and dental fields as osteoconductive bone substitutes. However, BCP scaffolds are not satisfactory for the stimulation of osteogenic differentiation and maturation. To enhance osteogenic differentiation, we prepared alendronate- (ALN- eluting BCP scaffolds. The coating of ALN on BCP scaffolds was confirmed by scanning electron microscopy (FE-SEM, energy-dispersive X-ray spectroscopy (EDS, and attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR. An in vitro release study showed that release of ALN from ALN-eluting BCP scaffolds was sustained for up to 28 days. In vitro results revealed that MG-63 cells grown on ALN-eluting BCP scaffolds exhibited increased ALP activity and calcium deposition and upregulated gene expression of Runx2, ALP, OCN, and OPN compared with the BCP scaffold alone. Therefore, this study suggests that ALN-eluting BCP scaffolds have the potential to effectively stimulate osteogenic differentiation.

    Full Text Available Kazuhiro Imai Department of Life Sciences, Graduate School of Arts and Sciences, The University of Tokyo, Tokyo, Japan Abstract: Osteoporosis is a skeletal disorder characterized by loss of bone mass, decreased bone strength, and an increased risk of bone fracture. The disease progresses with age, especially in postmenopausal women. Japan is one of the most rapidly aging societies worldwide. Japanese individuals over 65 years of age constituted 23.0% of the population in 2010 and 25.1% to 25.2% as of 2013. The estimated number of people with osteoporosis in Japan is currently 13 million. Bisphosphonates increase bone mineral density by inhibiting osteoclast-mediated bone resorption, thereby reducing the risk of fractures. Alendronate sodium hydrate (alendronate is a bisphosphonate that potently inhibits bone resorption and is used to treat osteoporosis. Sufficient water is required to take an alendronate oral tablet; insufficient water could result in digestive system diseases, such as esophageal ulceration. Elderly patients with swallowing difficulty may choke on the tablet. Taking a tablet with oral jelly is a method to prevent digestive system disease and reduce the choking hazard. Once-weekly alendronate oral jelly was approved in 2012 by the Ministry of Health, Labour, and Welfare of Japan as the world's first drug for osteoporosis in a jelly formulation. It consists of a jelly portion and an air portion. The jelly formulation is smoothly discharged by pushing the air portion. Therefore, elderly patients with physical disabilities are able to easily take all of the jelly formulation from the package. In this review, this new formulation of alendronate sodium hydrate (oral jelly is introduced and discussed in terms of osteoporosis treatment. This new formulation provides an alternative so that patients may select a method of dosing tailored to their preferences. Management of osteoporosis involves assessing fracture risk and preventing

    Two cases of radiation enterocolitis with markedly impaired QOL for a long period were reported. Case 1: A 61 years old female. She received 60 Gy irradiation post hysterectomy and ovariectomy due to uterine cancer at the age of 39 y. She suffered from fecal incontinence and anal pain at 58 y, was diagnosed to have radiation colitis. She was hospitalized due to neurosis, anal pain and hypertension at 59 y. She received nephrostomy due to hydronephrosis and ureterostenosis at 60 y, and colostomy and ileal conduit formation due to anal pain and dyschezia. Case 2: A 70 years old female who received 60 Gy irradiation post surgery similar to case 1 at the age of 61 y. She suffered from ileus, intestinal retention and hydronephrosis thereafter. She was hospitalized due to metastasis of the cancer to sacred bone, and received further 40 Gy radiation therapy at the age of 65 y. Up to the present, she received several operations such as ileostomy, nephrostomy and hemorrhoids excision. It is important for surgeons to understand the actual QOL of patients with radiation enterocolitis. (K.H.)

    Postmenopausal osteoporosis is a chronic disease wherein increased bone remodeling reduces bone mass and bone strength. Antiresorptive agents including bisphosphonates are commonly used to mitigate bone loss and fracture risk. Osteoclast inhibition via denosumab (DMAb), a RANKL inhibitor, is a newer approach for reducing fracture risk in patients at increased risk for fracture. The safety of transitioning from bisphosphonate therapy (alendronate; ALN) to DMAb was examined in mature ovariectomized (OVX) cynomolgus monkeys (cynos). One day after OVX, cynos (7-10/group) were treated with vehicle (VEH, s.c.), ALN (50 μg/kg, i.v., twice monthly) or DMAb (25 mg/kg/month, s.c.) for 12 months. Other animals received VEH or ALN for 6 months and then transitioned to 6 months of DMAb. DMAb caused significantly greater reductions in serum CTx than ALN, and transition from ALN to DMAb caused further reductions relative to continued ALN. DMAb and ALN decreased serum calcium (Ca), and transition from ALN to DMAb resulted in a lesser decline in Ca relative to DMAb or to VEH-DMAb transition. Bone histomorphometry indicated significantly reduced trabecular and cortical remodeling with DMAb or ALN. Compared with ALN, DMAb caused greater reductions in osteoclast surface, eroded surface, cortical porosity and fluorochrome labeling, and transition from ALN to DMAb reduced these parameters relative to continued ALN. Bone mineral density increased in all active treatment groups relative to VEH controls. Destructive biomechanical testing revealed significantly greater vertebral strength in all three groups receiving DMAb, including those receiving DMAb after ALN, relative to VEH controls. Bone mass and strength remained highly correlated in all groups at all tested skeletal sites, consistent with normal bone quality. These data indicate that cynos transitioned from ALN to DMAb exhibited reduced bone resorption and cortical porosity, and increased BMD and bone strength, without

    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.

To this experimental study the elderly women (65±6.40 years old) were randomly separated in experimental group (EG, n=31) and a control group (CG, n=28). A 6-min-walking test (aerobic resistance); a protocol of autonomy evaluation of the Latin-American Group for Maturity Development (functional autonomy), and the WHO QoL-old tests were utilized. The intervention happened with classes of recreation and walking practice, three times a week, for 1h, during 4 months. The results found revealed significant improvement for the EG at the aerobic resistance (Δ%=29.06%, p=0.0001), functional autonomy (Δ%=-27.15%, p=0.0001) and QoL (Δ%=15.47%, p=0.0001). It was concluded that the systematic physical exercise interferes in a positive way at the autonomy, aerobic resistance and QoL of the elderly women.

    Background A new treatment strategy is to target specific areas of the skeletal system that are prone to clinically significant osteoporotic fractures.We term this strategy as the "local treatment of osteoporosis".The study was performed to investigate the effect of alendronate-loaded calcium phosphate cement (CPC) as a novel drug delivery system for local treatment of osteoorosis.Methods An in vitro study was performed using CPC fabricated with different concentrations of alendronate (ALE,0,2,5,10 weight percent (wt%)).The microstructure,setting time,infrared spectrum,biomechanics,drug release,and biocompatibility of the composite were measured in order to detect changes when mixing CPC with ALE.An in vivo study was also performed using 30 Sprague-Dawley rats randomly divided into six groups:normal,Sham (ovariectomized (OVX) + Sham),CPC with 2% ALE,5%ALE,and 10% ALE groups.At 4 months after the implantation of the composite,animals were sacrificed and the caudal vertebrae (levels 4-7) were harvested for micro-CT examination and biomechanical testing.Results The setting time and strength of CPC was significantly faster and greater than the other groups.The ALE release was sustained over 21 days,and the composite showed good biocompatibility.In micro-CT analysis,compared with the Sham group,there was a significant increase with regard to volumetric bone mineral density (BMD) and trabecular number (Tb.N) in the treated groups (P <0.05).Trabecular spacing (Tb.Sp) showed a significant increase in the Sham group compared to other groups (P <0.01).However,trabecular thickness (Tb.Th) showed no significant difference among the groups.In biomechanical testing,the maximum compression strength and stiffness of trabecular bone in the Sham group were lower than those in the experimental groups.Conclusions The ALE-loaded CPC displayed satisfactory properties in vitro,which can reverse the OVX rat vertebral trabecular bone microarchitecture and biomechanical

    Systemic administration of bisphosphonates, e.g. sodium alendronate (Aln) is characterized by extremely low bioavailability and high toxicity. To omit aforementioned drawbacks an injectable system for the intra-bone delivery of Aln based on Aln-loaded nanoparticles (NPs-Aln) suspended in a hydrogel matrix (gellan gum, GG) was developed. Aln was encapsulated in poly(lactide-co-glycolide) (PLGA 85:15) by solid-oil-water emulsification. Drug release tests showed that within 25 days all the encapsulated drug was released from NPs-Aln and the release rate was highest at the beginning and decreased with time. In contrast, by suspending NPs-Aln in a GG matrix, the release rate was significantly lower and more constant in time. The GG-NPs-Aln system was engineered to be easily injectable and was able to reassemble its structure after extrusion as shown by rheological measurements. Invitro studies showed that the GG-NPs-Aln was cytocompatible with MG-63 osteoblast-like cells and it inhibited RANKL-mediated osteoclastic differentiation of RAW 264.7 cells. The injectability, the sustained local delivery of small doses of Aln and the biological activity render the GG-NPs-Aln system promising for the local treatment of osteoporosis and other bone tissue disorders.

    Microspheres of poly({beta}-hydroxybutyrate-co-{beta}-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.

    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.

    Severe short stature resulting from a deficiency in insulin-like growth factor-I (IGF-I) is a prominent feature of Laron syndrome (LS). Whether patients with LS are osteopenic or not, and whether they need treatment with bisphosphonates, remains uncertain. The aim of this study was to investigate the action of alendronate on the IGF-I-deficient bones of adult patients with LS and osteoporosis, as determined by dual X-ray absorptiometry . Seven patients (5 women and 2 men) of mean age 40.8+/-7.6 years and mean bone mass density (BMD) 0.843+/-0.06 g/cm2 (T score -2.9+/-0.5) at the lumbar spine and 0.734+/-0.11 g/cm2 (T score -2.2+/-0.9) at the femoral neck were treated with alendronate 70 mg once/weekly over a 12-month period. Treatment led to an increase of 5.3% in BMD (p=0.038) at the femoral neck. There was a similar trend at the lumbar spine, but the difference was not statistically significant (2.3%, p=0.34). Mean total alkaline phosphatase decreased by 14% from normal range at baseline (p=0.007). Urinary deoxypyridinoline levels, which were elevated at baseline (10+/-2.3 nM/mMcre), showed a nonsignificant change during treatment. Our study suggests that treatment with alendronate may have positive effects in patients with LS and low BMD on dual X-ray absorptiometry.

    Full Text Available This paper presents a review of some published proposals for the analysis of sodium alendronate. The drug is an aminobisphosphonate compound used to inhibit the osteoclastic resorption of bone, and different methods were developed for its quantitative determination. 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.

    Alendronate (ALN) is an antiresorptive agent widely used for the treatment of osteoporosis. Its suppressive effect on osteoclasts has been extensively studied. However, the effect of ALN on bone formation is not as clear as its effect on resorption. The objective was to determine the effect of short-term ALN on bone formation and tooth extraction wound healing. Molar tooth extractions were performed in mice. ALN, parathyroid hormone (PTH), or saline (vehicle control) was administered. PTH was used as the bone anabolic control. Mice were euthanized at 3, 5, 7, 10, and 21 d after extractions. Hard tissue healing was determined histomorphometrically. Neutrophils and lymphatic and blood vessels were quantified to evaluate soft tissue healing. Gene expression in the wounds was assessed at the RNA level. Furthermore, the vossicle bone transplant system was used to verify findings from extraction wound analysis. Alkaline phosphatase (ALP) was visualized in the vossicles to assess osteoblast activity. ALN exhibited no negative effect on bone formation. In intact tibiae, ALN increased bone mass significantly more than PTH did. Consistently, significantly elevated osteoblast numbers were noted. In the extraction sockets, bone fill in the ALN-treated mice was equivalent to the control. Genes associated with bone morphogenetic protein signaling, such as bmp2, nog, and dlx5, were activated in the extraction wounds of the ALN-treated animals. Bone formation in vossicles was significantly enhanced in the ALN versus PTH group. In agreement with this, ALN upregulated ALP activity considerably in vossicles. Neutrophil aggregation and suppressed lymphangiogenesis were evident in the soft tissue at 21 d after extraction, although gross healing of extraction wounds was uneventful. Bone formation was not impeded by short-term ALN treatment. Rather, short-term ALN treatment enhanced bone formation. ALN did not alter bone fill in extraction sockets.

    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: Black-Right-Pointing-Pointer The wear resistance, mechanical and physical properties UHMWPE-ALN 0.5 wt.% are not significantly different with those of UHMWPE. Black-Right-Pointing-Pointer The hydrophilicity of UHMWPE increased after loaded ALN. Black-Right-Pointing-Pointer The decrease of wear performance of UHMWPE-ALN 1.0 wt.% attributed to the non uniform distribution of ALN. Black-Right-Pointing-Pointer The ALN-agglomerated region of UHMWPE-ALN 1.0 wt.% was most easily worn out during wear processing.

    The aim of this study is to investigate the tribological behaviors and wear mechanisms of ultra-high molecular weight polyethylene (UHMWPE) loaded with alendronate sodium (ALN), a potential drug to treat osteolysis, under different normal loads and lubrication conditions. A mixture of UHMWPE powder and ALN (1.0 wt.%) solution was dried and hot pressed. The static and dynamic friction coefficients of UHMWPE-ALN were slightly higher than those of UHMWPE except under normal load as 10 N and in 25 v/v % calf serum. The specific wear rates of UHMWPE-ALN and UHMWPE were the lowest in 25 v/v % calf serum compared to those in deionized water or physiological saline. In particular, the specific wear rate of UHMWPE-ALN was lower than that of UHMWPE at 50 N in 25 v/v % calf serum. The main wear mechanisms of UHMWPE and UHMWPE-ALN in deionized water and UHMWPE in physiological saline were abrasive. The main wear mechanism of UHMWPE-ALN in physiological saline was micro-fatigue. In 25 v/v % calf serum, the main wear mechanism of UHMWPE and UHMWPE-ALN was abrasive wear accompanied with plastic deformation. The results of Micro-XRD indicated that the molecular deformation of UHMWPE-ALN and UHMWPE under the lower stress were in the amorphous region but in the crystalline region at the higher stress. These results showed that the wear of UHMWPE-ALN would be reduced under calf serum lubricated, which would be potentially applied to treat osteolysis.

    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.

    There is some evidence indicating that psychotropic medications might lead to health-related quality of life (QOL) improvements among children and adolescents with psychiatric disorders. The aim of this systematic review is to assess evidence regarding whether antidepressant treatment improves QOL among children and adolescents with depressive or anxiety disorders. A comprehensive search resulted in 5 clinical trials to be included in this review: 4 trials with major depressive disorder (MDD) and 1 trial with social anxiety disorder (SAD). In one MDD trial, fluoxetine combined with cognitive behavior therapy (CBT) significantly improved QOL compared to fluoxetine or CBT alone (effect sizes were 0.53 and 0.69, respectively). In 2 combined trials, sertraline alone significantly improved QOL among adolescents with MDD (effect size was 0.29), but not among children with MDD. Essentially, it was observed that antidepressants in these trials had minor positive effects on QOL improvement, which were lower than their potential to improve depressive symptoms. Although fluoxetine with CBT or sertraline monotherapy were shown to have some potential to improve QOL, this systematic review found inconclusive evidence that antidepressant treatments improve QOL among children and adolescents with depressive or anxiety disorders. More research is required, considering that QOL is currently under-evaluated in clinical trials with antidepressants among children and adolescents and available trials have limited methodological quality when reporting QOL data.

    Lumbago is one of the most prevalent symptoms in patients with osteoporotic vertebral fracture. Roland-Morris Disability Questionnaire (RDQ) is a quality of life (QOL) questionnaire targeted for evaluating lumbago. Although total score is the usual way of analysis, we have tried to make more use of it by subscale analysis. Forty-four osteoporotic patients were evaluated for their QOL using RDQ and SF-8; a widely accepted generic (non disease-specific) QOL questionnaire. Subscales and summary scores of SF-8 were significantly lower than Japanese norm. Patients with fracture had significantly lower scores including RDQ. Multiple regression analysis has shown that total score of RDQ was significantly contributed by bodily pain as well as other subscales of SF-8. Principal component analysis has revealed that RDQ consists of two components representing general, and mental or social aspect of lumbago. Defining the component structure and determining the procedure to obtain the subscales would make the most use of RDQ, and contribute to the better evaluation of patients with lumbago.

Principal component analysis has revealed that RDQ consists of two components representing general, and mental or social aspect of lumbago. Defining the component structure and determining the procedure to obtain the subscales would make the most use of RDQ, and contribute to the better evaluation of patients with lumbago. PMID:23885184

    Objectives To determine the skeletal safety and efficacy of long term (≥10 years) alendronate use in patients with osteoporosis. Design Open register based cohort study containing two nested case control studies. Setting Nationwide study of population of Denmark. Participants 61 990 men and women aged 50-94 at the start of treatment, who had not previously taken alendronate, 1996-2007. Interventions Treatment with alendronate. Main outcome measures Incident fracture of the subtrochanteric femur or femoral shaft (ST/FS) or the hip. Non-fracture controls from the cohort were matched to fracture cases by sex, year of birth, and year of initiation of alendronate treatment. Conditional logistic regression models were fitted to calculate odds ratios with and without adjustment for comorbidity and comedications. Sensitivity analyses investigated subsequent treatment with other drugs for osteoporosis. Results 1428 participants sustained a ST/FS (incidence rate 3.4/1000 person years, 95% confidence interval 3.2 to 3.6), and 6784 sustained a hip fracture (16.2/1000 person years, 15.8 to 16.6). The risk of ST/FS was lower with high adherence to treatment with alendronate (medication possession ratio (MPR, a proxy for compliance) >80%) compared with poor adherence (MPR 80% was associated with a decreased risk of hip fracture (0.73, 0.68 to 0.78; Pfracture outcomes, even for over 10 years of continuous use.

    Full Text Available Aim: The aim of this study was to assess and compare the response to two forms of treatment-immobilization with zoledronic acid injection and immobilization with oral weekly Alendronate, in patients with diabetes mellitus and acute Charcot arthropathy (CA of foot in terms of clinical and radiological parameters. Material and Methods: Patients attending the endocrinology and podiatry clinic with history of diabetes mellitus and Acute CA were taken for study. The patients were randomized into two treatment groups. Group Z-zoledronic acid injection along with total contact cast (TCC. Group A-Tab. Alendronate 70 mg. once a week till the complete clinical resolution of acute CA along with TCC. Forty-five patients were randomized and 40 of them completed the study. The primary end point was complete clinical resolution of acute CA-defined as temperature difference between normal and affected foot <1oF. Results: Among the 40 patients, 30 (75% had complete clinical resolution. The mean number of days taken for complete clinical resolution since the initiation of treatment (either Zoledronic acid or Alendronate was approximately 122 days. There was no significant difference in a number of days required for complete clinical resolution, between the two forms of therapy. There was more than 50% reduction in the visual score between the baseline and the final scan. The target to non-target ratio in the skeletal phase also showed an average of 40% reduction from the baseline to the final skeletal scintigraphy. Conclusion: Both Intravenous Zoledronic acid and oral alendronate had comparable efficacy with respect to the time taken for attaining complete clinical resolution of acute CA of foot. However, Alendronate therapy was cost effective among the two. 99m Tc MDP bone scan can be used as an adjuvant to the clinical parameters in assessing the response to therapy.

    Full Text Available 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.

    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

    BACKGROUND: Estrogen-replacement therapy prevents osteoporosis in postmenopausal women by inhibiting bone resorption, but the balance between its long-term risks and benefits remains unclear. Whether other antiresorptive therapies can prevent osteoporosis in these women is also not clear. METHODS......: We studied the effect of 2.5 mg or 5 mg of alendronate per day or placebo on bone mineral density in 1174 postmenopausal women under 60 years of age. An additional 435 women who were prepared to receive a combination of estrogen and progestin were randomly assigned to one of the above treatments...... or open-label estrogen-progestin. The main outcome measure was the change in bone mineral density of the lumbar spine, hip, distal forearm, and total body measured annually for two years by dual-energy x-ray absorptiometry. RESULTS: The women who received placebo lost bone mineral density at all measured...

    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.

    We herein report two cases of atypical femoral fracture (AFF). X-ray examinations at the first visit of these two female patients showed a complete fracture of the femoral diaphysis diagnosed as an atypical femoral fracture (AFF). X-rays of these two cases also showed localized cortical thickening of the femoral diaphysis. Both patients had been taking alendronate for more than 3 years because of postmenopausal osteoporosis. We assumed that both of the fractures were associated with the long-term use of alendronate. However, we retrospectively identified localized cortical thickening of the femoral diaphysis on an X-ray taken before the alendronate therapy in both of these cases. Therefore, we suspected a pathogenesis of AFFs in which preexisting stress or an insufficient fracture unrelated to bisphosphonate (BP) therapy and subsequent suppression of bone turnover due to BP administration led to the occurrence of an AFF. The patient underwent surgery using intramedullary nails in both of these cases, followed by the administration of teriparatide, and they were able to walk without any support at the final follow-up examination.

    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.

    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.

    Full Text Available The aim of this study was to compare the bone uptake of alendronate sodium (ALD from vaginal suppositories prepared with massa estarinum AB (ME and polyethylene glycol 1500 (PEG bases. For this purpose, ALD was radiolabeled with 99mTecnetium Pertechnetate (99mTc by direct method. Radiochemical purity and stability of 99mTc-ALD was performed with chromatographic studies. 99mTc-ALD containing suppositories were prepared with ME and PEG bases. Physical properties of suppositories were evaluated. The physicochemical diffusion study was carried out to compare the release of ALD from different suppository bases. The bone uptake of 99mTc-ALD was observed by gamma scintigraphy studies. 99mTc-ALD containing suppositories were administrated to rabbits via vaginal route. The scintigraphic images were obtained with a gamma camera at different time intervals up to 240 minutes. According to our studies, radiochemical purity of 99mTc-ALD was observed more than 95% up to 6 hours. At 240 minutes of physicochemical diffusion studies, released ALD has 0.620 ± 0.091 mm and 10.465 ± 0.651 mm diameter zone from ME and PEG base suppositories respectively. According to the gamma scintigraphy studies, although no bone uptake observed after ME suppositories application, rabbit’s bones were clearly visible after PEG suppositories applied. The results of physicochemical diffusion and gamma scintigraphy studies were found compatible in each other

    Full Text Available This study investigated the effect of alendronate (Aln released from biphasic calcium phosphate (BCP scaffolds. We evaluated the in vitro osteogenic differentiation of Aln/BCP scaffolds using MG-63 cells and the in vivo bone regenerative capability of Aln/BCP scaffolds using a rat tibial defect model with radiography, micro-computed tomography (CT, and histological examination. In vitro studies included the surface morphology of BCP and Aln-loaded BCP scaffolds visualized using field-emission scanning electron microscope, release kinetics of Aln from BCP scaffolds, alkaline phosphatase (ALP activity, calcium deposition, and gene expression. The in vitro studies showed that sustained release of Aln from the BCP scaffolds consisted of porous microstructures, and revealed that MG-63 cells cultured on Aln-loaded BCP scaffolds showed significantly increased ALP activity, calcium deposition, and gene expression compared to cells cultured on BCP scaffolds. The in vivo studies using radiograph and histology examination revealed abundant callus formation and bone maturation at the site in the Aln/BCP groups compared to the control group. However, solid bony bridge formation was not observed at plain radiographs until 8 weeks. Micro-CT analysis revealed that bone mineral density and bone formation volume were increased over time in an Aln concentration-dependent manner. These results suggested that Aln/BCP scaffolds have the potential for controlling the release of Aln and enhance bone formation and mineralization.

Although there have been important advances in defining and measuring QOL for this population, there is a need for interventions that are tied to standardized measurement and quality improvement programs. This paper describes the development and testing of a structured, tailored assessment and care planning process for improving the QOL of nursing home residents. The Quality of Life Structured Resident Interview and Care Plan (QOL.SRI/CP builds on a decade of research on measuring QOL and is designed to be easily implemented in any US nursing home. The approach was developed through extensive and iterative pilot testing and then tested in a randomized controlled trial in three nursing homes. Residents were randomly assigned to receive the assessment alone or both the assessment and an individualized QOL care plan task. The results show that residents assigned to the intervention group experienced improved QOL at 90- and 180-day follow-up, while QOL of residents in the control group was unchanged.

At 3-month follow up, the EQ-5D (self classifier and EQ-VAS was administered in consultation or by telephone. EQ-VAS varies from 0 (better HRQL to 100 (worst HRQL. An unweighted scoring for EQ5D-index was calculated. EQ5D-index ranges from -0.59 to 1. Test-retest reliability of the EQ-5D was tested using Kappa coefficient and intraclass correlation coefficient (ICC. Criterion validity was assessed by correlating EQ-VAS and EQ5D-index with the Short Form 36 (SF-36. Construct validity was tested using simple and multiple liner regression to assess factors influencing patients'HRQL. 145 survivors answered the EQ-5D. Median EQ5D-index was 0.52 [0.20-1]. Mean EQ-VAS was 62 ± 20. Test-retest reliability was conducted in 83 patients. ICCs of EQ5D-index and EQ-VAS were 0.95 and 0.92 respectively. For EQ-5D self classifier, agreement by kappa was above 0.40. Significant correlations were noted between EQ5D-index, EQ-VAS and SF-36 (p p = 0.017 and higher educational level (β = -0.2; p = 0.001. For EQ-VAS men were associated with better HRQL (β = 6.5; p = 0.048. Conclusions The Arabic version for Morocco of the EQ-5D is reliable and valid. Women, high educational level and longer ICU length of stay were associated with poorer HRQL.

    The Irritable Bowel Syndrome (IBS)-Quality of Life (QOL) is the most extensively validated health-related quality of life (HRQOL)-specific instrument for IBS with appropriate evidence for psychometric validity. Our aim was to linguistically validate the IBS-QOL for Mexico according to standard guidelines, to conduct further psychometric validation, and to compare the HRQOL between IBS patients from Mexico and North Carolina (University of North Carolina). Construct validity was tested by correlating scores from the Mexican Spanish IBS-QOL with those for anxiety and depression obtained by the Hospital Anxiety and Depression scale. Also, HRQOL from Rome I female IBS patients who consulted a tertiary referral center in Mexico was compared with that of female patients from UNC matched by age and bowel habit. A general univariate linear model was done to determine the most important variable over HRQOL, place of origin, or bowel habit. The majority of the IBS-QOL items had a negative correlation with depression as well as with anxiety. Compared to patients from UNC, the Mexican ones reported significant lower scores on Body Image and Health Worry and a trend in Interference with activities and in the Overall score. There were some differences in Dysphoria and Interference that were related to bowel habit, independently of the place of origin. In conclusion, the IBS-QOL validated in Mexican Spanish has shown construct validity. Using this instrument we found that female IBS patients who consulted a tertiary referral center in Mexico have lower HRQOL than those in North Carolina at least in factors such as Body Image and Health Worry.

    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......-point, validly identified women who responded, on ALN treatment, with a stabilization or an increase in bone mass. However, lack of decrease below the cut-point in NTX or OC could not be used to identify women with a bone loss during ALN treatment....

    Aim: The present study aims to compare the peri-implant bone status around immediately loaded dental implants treated with aminobisphosphonate solution and untreated control implants in terms of clinical and radiographical parameters. Materials and Methods: A total of 24 patients were randomly divided equally into two groups. This study was conducted in accordance to the Helsinki's declaration of 1975, revised in 2000, and with the approval of the institutional ethical committee. In the control group after preparation, osteotomy sites were irrigated with normal saline solution, whereas in the test group osteotomy sites were irrigated with modified bisphosphonate solution and then TRX-OP, Hi-Tec dental implants were inserted. Clinical parameters, such as modified plaque and gingival index, probing depth, mobility, and radiographic parameters were recorded at baseline (0), 3, 6, and 9 months. Data analysis was performed using the Statistical Package for the Social Sciences version 17 for windows, and the statistical techniques employed were repeated measures analysis of variance, independent sample t-test, and paired sample t-test. Results: Reduction in mean radiographic bone levels (height) was observed on the mesial and distal aspect of the control group in comparison to its baseline at all intervals. In the test group, there was reduction in mean radiographic bone levels on mesial and distal aspect of the implant site in comparison to its baseline till 6-month follow up, however, at 9 month, there was gain in bone level on both mesial and distal aspect of implant. This represents the effectiveness of sodium alendronate in enhancing the bone formation. On comparison, between both groups on mesial and distal aspect of implants, statistically significant differences were observed at 3 and 9 months on mesial and distal aspect, respectively, without any clinical evidence of mobility in the test group. Conclusion: Implant site treated with aminobisphosphonate solution

    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.

  17. Relief of BPO or improvement in quality of life?

    Benign prostatic hyperplasia (BPH) can cause benign prostatic enlargement with subsequent benign prostatic obstruction (BPO) and lower urinary tract symptoms (LUTS). A reduction in the size of the prostate has long been considered one of the most important treatment goals. However, there is a poor correlation between prostate size and both LUTS and BPO, and between BPO and symptoms. Today, the urologist's primary objectives are to minimize symptoms, relieve BPO and decrease the morbidity associated with BPO. From the patient's point of view, rapid relief of LUTS and immediate improvement in associated quality of life (QOL) are the most important factors. Although there is a good correlation between relief of symptoms (as measured by the International Prostate Symptom Score [I-PSS], for example) and associated improvement in bothersomeness and QOL, particularly that associated with filling ('irritative') symptoms, it is still important to quantify LUTS-related bothersomeness and QOL. Various questionnaires have been developed to measure bothersomeness (e.g. Symptom Problem Index [SPI], Danish PSS [DAN-PSS], International Continence Society BPH Study Group [ICSmale] questionnaire) and QOL (e.g. I-PSS-QOL, BPH Impact Index [BII] and QOL9 BPH-specific questionnaire). In addition, the impact of treatment on sexual function should also be taken into account when judging the overall well being or QOL of the patient. A grading system to evaluate the global improvement in patients following treatment has been established. Patients are either graded as showing 'slight', 'moderate' or 'marked' improvement, with the reduction in I-PSS or BII scores required for each classification dependent on baseline symptom severity. Medical treatment strategies designed to alleviate the symptoms of BPH and consequently improve the patient's QOL are now becoming increasingly important.

    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.

    Using alendronate and teriparatide simultaneously can increase bone mass density (BMD),but the effect was lower than that in teriparatide used alone.Using alendronate and terinaration in sequence can increase BMD,as well as bone microstructure and the homogeneous distribution of mineral substance.Using alendronate and teriparatide intermittently,such as using teriparatide for a while,and then combined with alendronate followed by alendronate treatment only,can increase BMD.Therefore,different combinations have positive but different effects on osteoporosis,which are helpful in providing the theoretical basis for osteoporosis treatment.%阿仑膦酸钠与特立帕肽同步应用,可增加骨密度,但疗效比特立帕肽单独治疗低.阿仑膦酸钠与特立帕肽序贯治疗,在增加骨密度的同时还能够促进骨组织微损伤修复和提高骨矿物质分布的均一性;阿仑膦酸钠与特立帕肽间断疗法,如在特立帕肽单药治疗基础上联合阿仑膦酸钠、然后停止特立帕肽并继续应用阿仑膦酸钠,可增加骨密度.不同联合方案对骨质疏松均有一定的疗效而作用不尽相同,为骨质疏松的临床治疗提供了理论依据.

    This study aimed at evaluating and describing the QoL and its association with the severity of disease among Brazilian Parkinson's disease (PD) patients. In this cross-sectional study 68 PD patients were interviewed using the World Health Organization Quality of Life Instrument Short Form (WHOQOL-BREF) and the Hoehn-Yahr (HY) scale. Analysis of variance, chi(2), Kruskal-Wallis and Mann-Whitney U-tests, Spearman and Cronbach reliability coefficients were used to analyze the data. The results indicate: (1) physical capacity was the domain that showed the most deterioration; (2) severity of PD is associated with QoL measured by WHOQOL-BREF; (3) overall QoL, working capacity, activities of daily living (ADL) and self-esteem are affected in both transitional periods in the progression of PD (mild to moderate and moderate to advanced). Satisfaction with general health, pain, energy, positive feelings, personal relationship and satisfaction with home are affected in the first period of transition while mobility, body image, sexual activity and access to information are affected in the second. This study mainly shows specific facets that are affected depending on the specific periods of PD progression, which can help to understand the impact of the disease, the effectiveness of care, and the demand for health care resources.

    Our objective was to investigate the protective effect of Lawesson's reagent, an H{sub 2}S 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 mm{sup 2}); 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 mm{sup 2}); 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 (K

    AIM: To compare postoperative quality of life (QOL) in patients with gastric cancer treated by esophagogastrostomy reconstruction after proximal gastrectomy.METHODS: QOL assessments that included functional outcomes (a 24-item survey about treatment-specific symptoms) and health perception (Spitzer QOL Index) were performed in 149 patients with gastric cancer in the upper third of the stomach, who had received proximal gastrectomy with additional esophagogastrostomy.RESULTS: Fifty-four patients underwent reconstruction by esophagogastric anterior wall end-to-side anastomosis combined with pyloroplasty (EA group); 45 patients had reconstruction by esophagogastric posterior wall end-to-side anastomosis (EP group); and 50 patients had reconstruction by esophagogastric end-to-end anastomosis (EE group). The EA group showed the best postoperative QOL, such as recovery of body weight, less discomfort after meals, and less heart burn or belching at 6 and 24 mo postoperatively. However, the survival rates, surgical results and Spitzer QOL index were similar among the three groups.CONCLUSION: Postoperative QOL was better in the EA than EP or EE group. To improve QOL afterproximal gastrectomy for upper third gastric cancer, the EA procedure using a stapler is safe and feasible for esophagogastrostomy.

    Objective To evaluate the effect of salmon calcitonin combined with alendronate sodium on bone and joint pain, and to observe the changes of bone mineral density ( BMD) , and the serum concentrations of bone Gla protein (BGP) and calcitonin (CT) in senile osteoporosis patients. Methods Seventy-four senile osteoporosis patients in our hospital were treated with salmon calcitonin combined with alendronate sodium. All of them were given an intramuscular injection of 50 IU salmon calcitonin once every other day. After 15 continuous injections, they were given an oral medication of 1 capsule alendronate sodium once a week. The whole treatment lasted for 6 months. The degree of bone and joint pain before and after treatment was estimated with visual analogue scale (VAS). BMD of the lumbar vertebrae (L2-L4) , the femur neck, and Wards region was tested before and after the treatment. Serum concentrations of BGP and calcitonin were tested before and after the treatment. All the results were statistically analyzed. Results After 6-month treatment with salmon calcitonin combined with alendronate sodium in senile osteoporosis patients, the relief of pain in bone and joint was obvious , and the difference was significant ( P < 0. 01). BMD and the serum concentrations of BGP and calcitonin after the treatment were significantly different from those before the treatment (P < 0. 05 ). Conclusion The treatment with salmon calcitonin combined with alendronate sodium in senile osteoporosis patients can significantly improve BMD and serum concentration of calcitonin, and can reduce the serum concentration of bone Gla protein , relieve bone and joint pain in patients, ameliorate the symptoms, and increase BMD.

    Objective To describe the development and psychometric properties of the Spinal Cord Injury-Quality of Life (SCI-QOL) Self-esteem item bank. Design Using a mixed-methods design, we developed and tested a self-esteem item bank through the use of focus groups with individuals with SCI and clinicians with expertise in SCI, cognitive interviews, and item-response theory- (IRT) based analytic approaches, including tests of model fit, differential item functioning (DIF) and precision. Setting We tested a pool of 30 items at several medical institutions across the United States, including the University of Michigan, Kessler Foundation, the Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital, and the James J. Peters/Bronx Department of Veterans Affairs hospital. Participants A total of 717 individuals with SCI completed the self-esteem items. Results A unidimensional model was observed (CFI = 0.946; RMSEA = 0.087) and measurement precision was good (theta range between −2.7 and 0.7). Eleven items were flagged for DIF; however, effect sizes were negligible with little practical impact on score estimates. The final calibrated item bank resulted in 23 retained items. Conclusion This study indicates that the SCI-QOL Self-esteem item bank represents a psychometrically robust measurement tool. Short form items are also suggested and computer adaptive tests are available. PMID:26010972

    The EuroQol five-dimensional (EQ-5D) questionnaire is used worldwide as a patient-reported outcome (PRO) instrument for the measurement and valuation of health. Several variants of the instrument now exist, including versions with three and five levels of severity and one for respondents aged 8 to 14 years. From the outset, a demand for new language versions of the EQ-5D questionnaire meant that there was a need to implement standardized procedures, which ensured that such versions were produced following international recommendations for the cultural adaptation of patient-reported outcomes. The availability of new variants and formats of the instrument, such as telephone-administered or electronic formats, complicated the task of providing and controlling the quality of cultural adaptations. Although cultural adaptations of the instrument are widely used, the procedures currently used to produce them have not been widely disseminated. The present article therefore describes the evolution of the production of other language versions of the instrument from the earliest days of simultaneous production and translation of the EQ-5D questionnaire to the more recent, broader-based strategy of version management. We describe current adaptation procedures and innovations within those procedures. We also describe how version management is organized within the EuroQol Group, review aspects related to quality control, and provide an overview of the number of currently available language versions for each variant of the EQ-5D questionnaire: three-level, five-level, and youth versions. We conclude by discussing some of the relevant issues related to cultural adaptation for frequently used instruments such as the EQ-5D questionnaire.

    Waon therapy (WT), which in Japanese means soothing warmth, is a repeated sauna therapy that improves cardiac and vascular endothelial function in patients with chronic heart failure (CHF). We investigated whether WT could improve the quality of life (QOL) of CHF patients in addition to improving cardiac function and exercise capacity.A total of 49 CHF patients (69 ± 14 years old) were treated with a 60°C far infrared-ray dry sauna bath for 15 minutes and then kept in a bed covered with blankets for 30 minutes once a day for 3 weeks. At baseline and 3 weeks after starting WT, cardiac function, 6-minute walk distance (6MWD), flow mediated dilation (FMD) of the brachial artery, and SF36-QOL scores were determined.WT significantly improved left ventricular ejection fraction (LVEF), B-type natriuretic peptide (BNP), 6MWD, and FMD (3.6 ± 2.3 to 5.1 ± 2.8%, P improved not only the physical (PC) but also mental component (MC) of the QOL scores. WT-induced improvement of PC was negatively correlated with changes in BNP (r = -0.327, P improvement was not related directly to changes in BNP, LVEF, or 6MWD. WT-induced changes in MC were not parallel to PC improvement.WT improved QOL as well as cardiac function and exercise capacity in patients with CHF. Mental QOL improved independently of WT-induced improvement of cardiac function and exercise capacity.

    Full Text Available Abstract Background Among people living with HIV (PLHIV on antiretroviral therapy (ART, it is important to determine how quality of life (QOL may be improved and HIV-related stigma can be lessened over time. This study assessed the effect of peer support on QOL and internal stigma during the first year after initiating ART among a cohort of PLHIV in north-eastern Vietnam. Methods A sub-sample study of a randomised controlled trial was implemented between October 2008 and November 2010 in Quang Ninh, Vietnam. In the intervention group, participants (n = 119 received adherence support from trained peer supporters who visited participants’ houses biweekly during the first two months, thereafter weekly. In the control group, participants (n = 109 were treated according to standard guidelines, including adherence counselling, monthly health check and drug refills. Basic demographics were measured at baseline. QOL and internal stigma were measured using a Vietnamese version of the WHOQOL-HIVBREF and Internal AIDS-related Stigma Scale instruments at baseline and 12 months. T-tests were used to detect the differences between mean values, multilevel linear regressions to determine factors influencing QOL. Results Overall, QOL improved significantly in the intervention group compared to the control group. Among participants initiating ART at clinical stages 3 and 4, education at high school level or above and having experiences of a family member dying from HIV were also associated with higher reported QOL. Among participants at clinical stage 1 and 2, there was no significant effect of peer support, whereas having children was associated with an increased QOL. Viral hepatitis was associated with a decreased QOL in both groups. Lower perceived stigma correlated significantly but weakly with improved QOL, however, there was no significant relation to peer support. Conclusion The peer support intervention improved QOL after 12 months among ART

    2015-01-01

    Full Text Available IINTRODUCTION. Remission criteria of acromegaly are based on biochemical variables, i.e. normalization of increased hormone levels. However, the established reduction in Quality of Life (QoL is suggested to be independent of biochemical control. The aim of this study was to test which aspects predict Qol best in acromegaly. METHODS/Design. This is a prospective cohort study in 80 acromegalic patients, with a cross-sectional and longitudinal part. The main outcome measure was health-related quality of life (QoL, measured by a generic and a disease-specific questionnaire (the SF-36 and AcroQol. Main predictors were age, gender, biochemical control, disease characteristics, treatment modalities and psychopathology. RESULTS. Our cohort of 80 acromegalics had a mean age 54.7 ± 12.3 years with an average disease duration of 10.8 ± 10.0 years. Ratio macro-/microadenoma was 54/26. In adjusted mixed method models, we found that psychopathology significantly predicts QoL in acromegaly (in models including the variables age, gender, disease duration, tumor size, basal hormone levels, relevant treatment modalities and relevant comorbidities, with a higher degree of psychopathology indicating a lower QoL (depression vs. AcroQoL: B=-1.175, p<0.001, depression vs. SF36: B=-1.648, p<0.001, anxiety vs. AcroQoL: B=-0.399, p<0.001, anxiety vs. SF36: B=-0.661, p<0.001. The explained variances demonstrate superiority of psychopathology over biochemical control and other variables in predicting QoL in our models. DISCUSSION. Superiority of psychopathology over biochemical control calls for a more extensive approach regarding diagnosing depression and anxiety in pituitary adenomas to improve QoL. Depressive symptoms and anxiety are modifiable factors that might provide valuable targets for possible future treatment interventions.

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

    The aim of this study was to investigate the in vitro release and the effect of RAW 264.7 macrophages of critical-sized wear particles of ultra-high molecular weight polyethylene (UHMWPE) loaded with alendronate sodium (ALN), one of the most effective drugs to treat osteoporosis in clinic. The critical-sized UHMWPE-ALN 0.5 wt.% wear particles were prepared by vacuum gradient filtration combined with Pluronic F-68. In vitro release of ALN from critical-sized UHMWPE-ALN wear particles was investigated in phosphate buffered saline (PBS) at 37 °C with a shaker. Cell morphology, proliferation, lactate dehydrogenase (LDH) leakage and secretions of cytokines were evaluated after co-cultured with critical-sized UHMWPE-ALN wear particles in vitro. Results showed that ALN released from critical-sized UHMWPE-ALN wear particles included burst release and slow release in vitro. Macrophages would be chemotaxis and aggregated around the critical-sized UHMWPE-ALN or UHMWPE wear particle, which was phagocytosed with time. The proliferation of macrophages co-cultured with critical-sized UHMWPE-ALN wear particles was significantly decreased compared with that of critical-sized UHMWPE group. Meanwhile, the critical-sized UHMWPE-ALN wear particles significantly induced the LDH leakage of macrophages, which indicated the cell death. The death of macrophages induced by ALN was one of pathways to inhibit their proliferation. The secretions of cytokines (interleukin-6 and tumor necrosis factor-alpha) in critical-sized UHMWPE-ALN group were significantly lower than those in critical-sized UHMWPE group due to the released ALN. The present results suggested that UHMWPE-ALN had the potential application in clinic to treat osteolysis induced by wear particles.

    Parathyroid hormone (PTH) is the anabolic standard of care for patients with severe osteoporosis. The CaSR allosteric antagonist JTT-305/MK-5442, a PTH secretagogue, could offer an oral osteoanabolic treatment alternative for postmenopausal women with osteoporosis. Here we disclose the pharmacokinetic profile of JTT-305/MK-5442 and its activity on bone remodeling in ovariectomized (OVX) osteopenic rats. Daily treatments (0.3 to 2.4 mg/kg/d) for 12 weeks resulted in plateaued BMD increases (3.8 to 5.3%) at axial and appendicular skeletal sites. However, treatment effects were not statistically significant, in agreement with effects seen in animals treated with low dose PTH (1-84) (5 μg/kg/d). In a consecutive study we tested JTT-305/MK-5442 effects on bone formation in OVX-rats challenged with combined alendronate (ALN) treatment paradigms. At 7 month, JTT-305/MK-5442 treatment significantly increased BMD in lumbar vertebrae (LV), while no change in BMD was observed in femora or tibiae. ALN add-on co-treatment produced incremental increases in LV, distal femur (DF) and proximal tibia (PT) BMD over the respective ALN control. Histological analyses confirmed modest increases in mineralized surface (MS/BS) and bone formation rate (30.5±1.9%) on trabecular surfaces by JTT-305/MK-5442. As expected, ALN administration profoundly reduced bone formation, however, JTT-305/MK-5442 significantly stimulated MS/BS and BFR in ALN treated groups. In summary, JTT-305/MK-5442 acts as a PTH secretagogue in the osteopenic OVX-rat, eliciting consistent, though modest effects on remediation of BMD due to estrogen depletion. Induction of bone formation by JTT-305/MK-5442 at trabecular bone surfaces appears to be resilient to ALN-mediated suppression of bone formation. This study provides for the first time, a mechanistic evaluation of combination treatment of a PTH secretagogue with ALN.

    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%, pmonkeys 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 DXA-based aBMD and QCT-based vBMD. However, FN cortical mineral content clearly demonstrated superior efficacy of ODN versus ALN in this model of estrogen-deficient non-human primates.

    Women with breast cancer are naturally exposed to strain related to diagnosis and treatment, and this influences their experienced quality of life (QoL). The present paper reports the effect, with regard to QoL aspects, of an art therapy intervention among 41 women undergoing radiotherapy treatment for breast cancer. The women were randomized to an intervention group with individual art therapy sessions for 1 h/week (n = 20), or to a control group (n = 21). The WHOQOL-BREF and EORTC Quality of Life Questionnaire-BR23, were used for QoL assessment, and administrated on three measurement occasions, before the start of radiotherapy and 2 and 6 months later. The results indicate an overall improvement in QoL aspects among women in the intervention group. A significant increase in total health, total QoL, physical health and psychological health was observed in the art therapy group. A significant positive difference within the art therapy group was also seen, concerning future perspectives, body image and systemic therapy side effects. The present study provides strong support for the use of art therapy to improve QoL for women undergoing radiotherapy treatment for breast cancer.

    The purpose of this study was to determine the factors explaining changes in the generic quality of life among patients with Menière's disorder (MD) and to evaluate the EuroQol 5D (EQ-5D) quality-of-life measures. A questionnaire focusing on symptoms and disabilities caused by MD was collected from 726 individuals. General health-related quality of life (EQ-5D) was evaluated using the time trade-off (TTO) and visual-analogue scale (VAS). Personal traits were measured with the sense of coherence. The TTO-VAS score difference was modeled with activity limitations, participation restrictions, attitudes, and symptoms. For TTO as the outcome measure, one symptom-based, three attitude-based, one activity limitation, and one participation restriction item explained 43% of the variability. For VAS, six attitude-based, one symptom-based, three activity limitations, and one participation restriction item explained 43% of the variability of the data. The correlation between TTO and VAS (r=0.515, PTTO and VAS was reflected in attitudes towards the illness. The model explained 10% of the variability in the VAS and TTO difference. There was a disease duration effect in the TTO-VAS difference. In conclusion, a symptom-based model combined with disabilities provided a good description of general quality of life in MD. The TTO-based and VAS-based evaluation explained somewhat different aspects of MD. The difference between TTO and VAS could be described as an attitude toward the ailment. Evaluation of disabilities and the difference in TTO and VAS can be used to guide the rehabilitation to promote attitude change.

    This study evaluates predictors of health-related quality of life (HRQoL) and fatigue in systemic sclerosis (SSc) using two novel self-report indices. A cross-sectional study of patients with SSc was undertaken using a postal questionnaire including the EuroQol-5Domain health questionnaire (EQ-5D™), Functional Assessment of Chronic Illness Therapy-Fatigue scale (FACIT-F) and the Scleroderma Health Assessment Questionnaire (SHAQ). The EQ-5D assesses five domains of health quality and is quantified as a time trade-off (TTO) value and patient global assessment (0-100 visual analogue scale [VAS]). The FACIT-F is a 13-item questionnaire (0-52 scale). Higher scores for both the EQ-5D and FACIT-F indicate better health. Case notes were scrutinised for patient demographics, disease duration, serology and clinical phenotype. Sixty-eight patients (60 females, mean age 62.6 years) completed the questionnaires. Fatigue correlated closely with HRQoL (r (s) = 0.78 and 0.77 for FACIT-F vs. EQ-5D VAS and TTO respectively, p < 0.01) and disability (r (s) = -0.74 for FACIT-F vs. HAQ-DI, p < 0.01). Pain was the most frequently reported health problem (80 %) in the EQ-5D. HRQoL also correlated closely with disability (r (s) = 0.83 for EQ-5D vs. HAQ-DI, p < 0.01). SHAQ-VAS scores correlated well with the FACIT-F, EQ-5D and HAQ-DI scores (p < 0.05 for all comparisons). Of the patient demographics and clinical disease associations, only the absence of upper gastrointestinal complications was associated with better levels of fatigue, HRQoL and function. There is a strong correlation between disability, fatigue and HRQoL measured using self-reports, possibly reflecting similarly perceived health beliefs amongst patients across outcomes. There was little association between self-report indices and patient demographics and/or clinical phenotype.

    While in other chronic diseases combined treatment regimens are the rule there is a lack of reported experience or study data on combining different specific drugs to treat osteoporosis. Significant differences in the mode of action (MOA) of the substances to be combined may be important for achieving optimal therapeutic results. Recognising that today bisphosphonates are the leading therapy for osteoporosis we suggest that the active D-hormone analog alfacalcidol with its completely different mechanisms of action could be an interesting combination to improve the therapeutic outcome of the pure antiresoptive action of bisphosphonates. Alfacalcidol is activated by the enzyme 25-hydroxylase in the liver for systemic and in osteoblasts for local D-hormone actions. It possesses a unique pattern of pleiotropic effects on, e.g. gut, bone, pararthyroids, muscle and brain. Alfacalcidol is superior to plain vitamin D (cholecalciferol) because the final kidney activation of the latter is regulated by a negative feedback mechanism. In vitamin D replete patients or patients with impaired kidney function no increased D-hormone action at the target tissues can be achieved. Animal studies and several trials in humans with alendronate plus calcitriol or alfacalcidol proved that the combination induced significantly higher increases of bone mineral density (BMD) than the respective mono-therapies. The results of the 2-year AAC-trial from our group indicate that the combination alendronate and alfacalcidol is also superior in terms of falls, fractures and back pain. From the review of the literature and the own new results we conclude that this combined therapeutic regimen is a very promising option for treating established osteoporosis and propose a differentiated use of alfacalcidol alone or the combination with alendronate in different stages and clinical situations of osteoporosis.

    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 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.

    Objectives To investigate longitudinal changes in behavior and quality-of-life (QoL) in children with sleep disordered breathing (SDB) after adenotonsillectomy (AT). Methods This study prospectively enrolled 148 children who underwent AT for SDB. Caregivers filled out Korean attention deficit hyperactivity disorder (ADHD) rating scale (K-ARS) and Korean version of the obstructive sleep apnea-18 (KOSA-18) at preoperative 1 day, postoperative 1 month, and postoperative 6 months. Longitudinal changes in K-ARS and KOSA-18 were evaluated and compared among subgroups. Results Both K-ARS and KOSA-18 scores improved immediately at postoperative 1 month and were maintained at postoperative 6 months. The mean preoperative K-ARS scores of the non-ADHD, ADHD-trait, and overt-ADHD groups showed uniformly immediate and sustained improvements. Also, the mean preoperative KOSA-18 scores of the small, moderate, and large impact groups were significantly improved both at postoperative 1 month and 6 months. The changes in behavior and QoL showed no significant differences with regard to the aforementioned factors. Conclusion After AT, we may expect immediate and sustained improvements in behavior and QoL in children with SDB regardless of preoperative symptom severity. Moreover, by performing AT, improvements in behavior and QoL are expected regardless of sex, age, allergic trait, or concurrent coblation-assisted turbinoplasty. These findings may help our colleague physicians counselling pediatric SDB patients and their caregivers. PMID:27090276

    course of disease was 9.71 years. There were 7 (25%) patients with abnormal MKI images and 12 (42.86%) patients with a very low IQ (FIQ ≤50). The percentages of seizure freedom at 1KU and 5FU reached 17.86% and 10.71% , respectively. The percentages of patients with 50% or more seizure frequency reduction at 1FU and 5FU were 64.28% and 57.14%,respectively. No statistically significant difference was found in seizure control between lFUand5FU (P>0.05). The improvement of FIQ at 1FU was presented in 13 cases (46.43 %), and 64.28 % (18/28) patients rendered an improvement in total QOL. Postoperative seizure control was not correlated in the changes of IQ and QOL. Postoperative transient complications were seen in 4 cases, but no long-term complication occurred. Conclusions Anterior CCT is promising and safe for patients with LGS at adolescence. It is conducive to the patients' QOL and IQ improvement and suitable for surgical treatment of LGS.

    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

    利用社会调查资料,借鉴生活质量与贫困概念,分析西安市单亲女性群体的生活质量与贫困化现状。研究结果表明:(1)与已婚家庭女性群体相比,她们的客观生活质量和主观生活质量均明显偏低。(2)因为离婚或丧偶,经济收入、健康状况和抚养子女及住房压力显著影响她们的生活质量。(3)她们的经济满意度、居住满意度和生活总体满意度之间具有显著的正向相关关系。(4)考虑到生活质量,她们已经成为城市贫困中不可忽视的重要群体。分析城市单亲女性群体的生活质量有利于把握其贫困程度。建议,将她们纳入社会保障体系中重点优抚,特别是就业保障和住房保障应成为政府制定政策重点考虑的事项。%Using the data of social investigation and the concept of quality of life (QOL) and poverty, the paper analyzes the current situation of the QOL and the impoverishment of the single women with children in Xi’an city. The research results show:(1)Compared with the married women, single women’s objective quality of life and subjective quality of life are signifi-cantly lower;(2)Because of divorce or widow, economic income, health condition and raising children and housing pressure greatly influence their quality of life;(3)Their subjective quality of life has significant positive correlation among the econom-ic, resident and overall satisfaction;(4)In consideration of the seriousness of their QOL,they have become urban poverty pop-ulation that cannot be ignored. To study urban single women’s quality of life is helpful to master their impoverishment and of-ficial policy should emphatically consider the social vulnerable groups. The article suggests that they should be brought into the social security system prioritized by governments,especially the employment security and housing security.

  7. Cardiac rehabilitation: a good measure to improve quality of life in peri- and postmenopausal women with microvascular angina

    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.

    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.

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

    The choice of general (GA) versus local anesthesia (LA) in open inguinal hernia repair (OIHR) has a substantial financial impact and may influence clinical outcomes. Our study compares postoperative quality of life (QOL) in patients undergoing OIHR under LA versus GA. A cooperative prospective study from centers in 10 countries was performed through the International Hernia Mesh Registry from 2007 to 2012. QOL was compared at one, six, 12, and 24 months for LA versus GA with univariate and multivariate analysis controlling for known confounding variables. Of 1128 patients who underwent OIHR, 585(52%) used GA and 533(48%) used LA. Most were male (92%) with unilateral (94%), primary (91%) repairs with a mean age 57 ± 16 years. There was no difference (P > 0.05) in age, gender, operative time, mesh size, length of stay, infection, recurrence, reoperation, or death. Multivariate analysis demonstrated significant QOL differences between groups: GA had higher odds of discomfort at one and six months [odds ratio (OR) 3.3, 2.0], movement limitation at one and six months (OR 3.5, 2.8), and mesh sensation at one and 12 months (OR 2.9, 1.8). Overall, patients undergoing OIHR under LA had improved postoperative QOL in the short and long term compared with GA.

    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.

    The antifracture efficacy of vitamin D in osteoporosis is due to its direct action on bones and indirect extraskeletal effects to prevent falls. Eldecalcitol is an analog of active vitamin D3 that improves bone mineral density and reduces the risk of osteoporotic fractures. However, the effects of eldecalcitol on muscle strength and static and dynamic postural balance are unclear. In this open-label randomized controlled study, we assessed the effects of eldecalcitol on muscle strength and static and dynamic postural balance in 50 postmenopausal women (mean age 74 years) with osteoporosis treated with bisphosphonate. Participants were randomly divided into a bisphosphonate group (alendronate at 35 mg/week; n = 25) or an eldecalcitol group (eldecalcitol at 0.75 μg/day and alendronate at 35 mg/week; n = 25) and were followed up for 6 months. Trunk muscle strength, including back extensor strength and iliopsoas muscle strength, was measured. Static standing balance was evaluated and the one leg standing test was performed to assess static postural balance. Dynamic sitting balance was evaluated and the 10-m walk test, functional reach test, and timed up and go test were performed to assess dynamic postural balance. At 6 months, there were no significant changes in any measure of muscle strength or balance in the bisphosphonate group, whereas eldecalcitol significantly increased back extensor strength (p = 0.012) and iliopsoas muscle strength (p = 0.035). Eldecalcitol also significantly improved findings on the timed up and go test (p = 0.001) and dynamic sitting balance (p = 0.015) at 6 months. These results with eldecalcitol may have an impact on prevention of falls.

    Objective. Adults with attention deficit hyperactivity disorder (ADHD) display affective problems and impaired attention. Mood in ADHD can be improved by mindful awareness practices (MAP), but results are mixed regarding the enhancement of attentional performance. Here we evaluated MAP-induced changes in quality of life (QoL), mood, and attention in adult ADHD patients and controls using more measures of attention than prior studies. Methods. Twenty-one ADHD patients and 8 healthy controls underwent 8 weekly MAP sessions; 22 similar patients and 9 controls did not undergo the intervention. Mood and QoL were assessed using validated questionnaires, and attention was evaluated using the Attentional Network Test (ANT) and the Conners Continuous Performance Test (CPT II), before and after intervention. Results. MAP enhanced sustained attention (ANT) and detectability (CPT II) and improved mood and QoL of patients and controls. Conclusion. MAP is a complementary intervention that improves affect and attention of adults with ADHD and controls. PMID:26137496

    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.

    For patients with nonsmall cell lung cancer (NSCLC) receiving chemotherapy, current clinical evidence has indicated add-on benefit of Chinese herbal medicine (CHM) in improving quality of life (QoL). However, the relative performance among different CHM is unknown. The aim of this overview of systematic reviews (SRs) and network meta-analyses (NMA) is to evaluate the comparative effectiveness of different CHM. Seven electronic databases including both international databases and Chinese databases were searched. SRs focus on randomized controlled trials (RCTs) with comparison of CHM plus chemotherapy against chemotherapy alone on QoL among NSCLC patients were considered eligible. Data from RCTs were extracted for random effect pairwise meta-analyses. Pooled relative risk (RR) with 95% confidence interval (CI) was used to quantify the impact of CHM on QoL. NMA was used to explore the most effective CHM for improving QoL when used with chemotherapy. From 14 SRs, 61 RCTs (n = 4247) assessing 11 different CHM were included. Result from pairwise meta-analyses showed 6 CHM (Kang-lai-te injection, Shei-qi-fu-zheng injection, Compound ku-shen injection, Kang-ai injection, Zi-jin-long tablet, and Shen-fu injection) has significant beneficial effect on QoL among NSCLC patients when used with chemotherapy, even after adjustment for publication bias. Pooled RR varied from 1.38 (95% CI: 1.11-1.72, I2 = 0.0%, Kang-lai-te injection) to 3.36 (95% CI: 1.30-8.66, I2 = 0.0%, Zi-jin-long tablet). One trial comparing Hai-shen-su (a protein extract from Tegillarca granosa L.) plus chemotherapy with chemotherapy also demonstrated beneficial effect of combined treatment (RR = 3.13, 95% CI: 1.41-6.98). Results from NMA showed no differences on the comparative effectiveness among CHM, but Hai-shen-su plus chemotherapy has the highest probability (62.3%) of being the best option for improving QoL. Use of CHM on top of chemotherapy can significantly improve QoL in NSCLC patients. Although Hai

    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.

    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

    Due to concern over long term safety of continuous treatment with cyclosporin, the aim of this 1-year study was to assess the effect of intermittent therapy with cyclosporin (Neoral) on the quality of life of patients suffering from chronic plaque psoriasis. A total of 41 patients with chronic plaque psoriasis (26 male, mean age: 36 years, range: 18-61; duration of psoriasis 17 years, range: 2-31) entered a 9-centre open study in which cyclosporin was taken as an initial dose of 5 mg/kg/daily for a maximum of 12 weeks for up to three cycles. Each patient completed a psoriasis specific QOL measure (Psoriasis Disability Index, PDI) at the beginning and end of each treatment cycle and at the end of study. Clinical parameters including Psoriasis Area and Severity Index (PASI) were measured. The PDI scores showed a significant improvement (p < 0.01) between the beginning and end of all three treatment cycles. The various clinical assessments for each treatment period also showed significant improvement (p < 0.001) for all three cycles. When comparing the last follow-up value to baseline there was a clear indication of relapse, but these scores were still significantly better than at baseline (p < 0.01). Notably, the mean PASI score improved by more than 50% (p < 0.001) between first baseline and end of the study. These findings indicate that a short course of intermittent therapy with cyclosporin in microemulsion formulation, used at starting doses of 5 mg/kg/day, improves QOL of patients with chronic plaque psoriasis. Once again, the applicability and validity of the PDI as a useful QOL tool has been demonstrated.

Cordyceps sinensis is a traditional Chinese medicine that is evaluated clinically for the treatment of many diseases, such as chronic allograft nephropathy, diabetic kidney disease, and lung fibrosis. In order to investigate the effects of Cordyceps sinensis on patients with moderate-to-severe persistent asthma, 120 subjects were randomized to receive Corbin capsule containing Cordyceps sinensis for 3 months (treatment group, n=60, whereas the control group (n=60 did not receive treatment with Corbin capsule. Inhaled corticosteroid and as-needed β-agonists were used in the treatment of both groups. HR-QOL was measured with the Juniper’s Asthma Quality of Life Questionnaire (AQLQ. The incidence of asthma exacerbation, pulmonary function testing, and serum measurements of inflammatory mediators were also evaluated. The results showed that the treatment group indicated a significant increase in AQLQ scores and lung function compared with the control group. The expression levels of the inflammation markers IgE, ICAM-1, IL-4, and MMP-9 in the serum were decreased and IgG increased in the treatment group compared with the control group. Therefore, the conclusion was reached that a formulation of Cordyceps sinensis improved the HR-QOL, asthma symptoms, lung function, and inflammatory profile of the patients with moderate-to-severe asthma.

    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 Gilles de la Tourette Syndrome (GTS is characterized by motor and vocal tics, as well as associated comorbid conditions including obsessive-compulsive disorder (OCD, attention deficit/hyperactivity disorder (ADHD, depression, and anxiety which are present in a substantial number of patients. Although randomized controlled trials including a large number of patients are still missing, aripiprazole is currently considered as a first choice drug for the treatment of tics. The aim of this study was to further investigate efficacy and safety of aripiprazole in a group of drug-free, adult patients. Specifically, we investigated the influence of aripiprazole on tic severity, comorbidities, premonitory urge (PU, and quality of life (QoL. Moreover we were interested in the factors that influence a patient’s decision in electing for-or against- pharmacological treatment. In this prospective uncontrolled open-label study, we included 44 patients and used a number of rating scales to assess tic severity, PU, comorbidities, and QoL at baseline and during treatment with aripiprazole. 18 out of 44 patients decided for undergoing treatment for their tics with aripiprazole and completed follow-up assessments after 4-6 weeks. Our major findings were (1 aripiprazole resulted in significant reduction of tics, but did not affect PU; (2 aripiprazole significantly improved OCD and showed a trend towards improvement of other comorbidities including depression, anxiety and ADHD; (3 neither severity of tics, nor PU or QoL influenced patients’ decisions for or against treatment of tics with aripiprazole; instead patients with comorbid OCD tended to decide in favor of, while patients with comorbid ADHD tended to decide against tic treatment; (4 most frequently reported adverse effects were sleeping problems; (5 patients’ QoL was mostly impaired by comorbid depression.

    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.

    Allogeneic hematopoietic stem cell transplantation (HSCT) is rarely performed in adult patients with sickle cell disease (SCD). We utilized the chemotherapy-free, alemtuzumab/total body irradiation 300 cGy regimen with sirolimus as post-transplantation immunosuppression in 13 high-risk SCD adult patients between November 2011 and June 2014. Patients received matched related donor (MRD) granulocyte colony-stimulating factor-mobilized peripheral blood stem cells, including 2 cases that were ABO incompatible. Quality-of-life (QoL) measurements were performed at different time points after HSCT. All 13 patients initially engrafted. A stable mixed donor/recipient chimerism was maintained in 12 patients (92%), whereas 1 patient not compliant with sirolimus experienced secondary graft failure. With a median follow-up of 22 months (range, 12 to 44 months) there was no mortality, no acute or chronic graft-versus-host disease (GVHD), and no grades 3 or 4 extramedullary toxicities. At 1 year after transplantation, patients with stable donor chimerism have normalized hemoglobin concentrations and improved cardiopulmonary and QoL parameters including bodily pain, general health, and vitality. In 4 patients, sirolimus was stopped without rejection or SCD-related complications. These results underscore the successful use of a chemotherapy-free regimen in MRD HSCT for high-risk adult SCD patients and demonstrates a high cure rate, absence of GVHD or mortality, and improvement in QoL including the applicability of this regimen in ABO mismatched cases (NCT number 01499888).

    Full Text Available Adverse drug reaction (ADR is widely concerned for public health issue. ADRs are one of most common causes to withdraw some drugs from market. Prescription event monitoring (PEM is an important approach to detect the adverse drug reactions. The main problem to deal with this method is how to automatically extract the medical events or side effects from high-throughput medical events, which are collected from day to day clinical practice. In this study we propose a novel concept of feature matrix to detect the ADRs. Feature matrix, which is extracted from big medical data from The Health Improvement Network (THIN database, is created to characterize the medical events for the patients who take drugs. Feature matrix builds the foundation for the irregular and big medical data. Then feature selection methods are performed on feature matrix to detect the significant features. Finally the ADRs can be located based on the significant features. The experiments are carried out on three drugs: Atorvastatin, Alendronate, and Metoclopramide. Major side effects for each drug are detected and better performance is achieved compared to other computerized methods. The detected ADRs are based on computerized methods, further investigation is needed.

    Curcuminoids are bioactive polyphenolics with potent antiinflammatory properties. Although several lines of in vitro and preclinical evidence suggest potent anticancer effects of curcuminoids, clinical findings have not been conclusive. The present randomized double-blind placebo-controlled trial aimed to evaluate the efficacy of curcuminoids as adjuvant therapy in cancer patients. Eighty subjects with solid tumors who were under standard chemotherapy regimens were randomly assigned to a bioavailability-boosted curcuminoids preparation (180 mg/day; n = 40) or matched placebo (n = 40) for a period of 8 weeks. Efficacy measures were changes in the health-related quality of life (QoL) score (evaluated using the University of Washington index) and serum levels of a panel of mediators implicated in systemic inflammation including interleukins 6 (IL-6) and 8 (IL-8), TNF-α, transforming growth factor-β (TGFβ), high-sensitivity C-reactive protein (hs-CRP), calcitonin gene-related peptide (CGRP), substance P and monocyte chemotactic protein-1 (MCP-1). Curcuminoid supplementation was associated with a significantly greater improvement in QoL compared with placebo (p life variations were associated with changes in serum TGFβ levels in both correlation and regression analyses. Adjuvant therapy with a bioavailable curcuminoid preparation can significantly improve QoL and suppress systemic inflammation in patients with solid tumors who are under treatment with standard chemotherapy protocols.

    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.

    Full Text Available Abstract 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

    Breast cancer patients suffer impairment in cardiorespiratory fitness after treatment for primary disease, affecting patients' health and survival. The aim of this study was to evaluate the ability of a pragmatic exercise intervention to improve cardiorespiratory fitness of breast cancer patients after primary treatment. Between February 2013 and December 2014, 94 women with early stage (I-III) breast cancer, 1-36 months post-chemotherapy, and radiotherapy were randomly assigned to an intervention program (EX) combining supervised aerobic and resistance exercise (n = 44) or usual care (CON) (n = 45) for 12 weeks. Primary study endpoint was VO2max. Secondary endpoints were muscle strength, shoulder range of motion, body composition, and quality of life (QoL). Assessments were undertaken at baseline, 12-week, and 6-month follow-ups. Eighty-nine patients aged 29-69 years were assessed at baseline and 12 weeks. The EX group showed significant improvements in VO2max, muscle strength, percent fat, and lean mass (p ≤ 0.001 in all cases) and QoL compared with usual care (CON). Apart from body composition, improvements were maintained for the EX at 6-month follow-up. There were no adverse events during the testing or exercise intervention program. A combined exercise intervention produced considerable improvement in cardiorespiratory fitness, physical function, and quality of life in breast cancer patients previously treated with chemotherapy and radiation therapy. Importantly, most of these benefits were maintained 6 months after ceasing the supervised exercise intervention.

    Previous research has shown that breathing exercises may improve the prognosis and health status in patients with lung cancer by enhancing pulmonary function and quality of life (QOL). However, individually published results are inconclusive. The aim of the present meta-analysis was to evaluate the clinical value of breathing exercises on post-operative pulmonary function and QOL in patients with lung cancer. A literature search of Pubmed, Embase, the Web of Science and CBM databases was conducted from their inception through to October 2012. Crude standardized mean differences (SMDs) with 95% confidence intervals (CIs) were used to assess the effect of breathing exercises. A total of eight clinical studies were ultimately included with 398 lung cancer patients. When all the eligible studies were pooled into the meta-analysis, there was a significant difference between the pre-intervention and post-intervention results of breathing exercises on post-operative pulmonary function; forced expiratory volume in 1 sec (FEV1): SMD, 3.37; 95% CI, 1.97-4.77; Pintervention with breathing exercises; there were significant differences between the pre-intervention and post-intervention results on the ability of self-care in daily life (SMD, -1.00; 95% CI, -1.467 to -0.52; P<0.001), social activities (SMD, -0.94; 95% CI, -1.73 to -0.15; P=0.02), symptoms of depression (SMD, -0.91; 95% CI, -1.25 to -0.57; P<0.001) and symptoms of anxiety (SMD, -0.91; 95% CI, -1.20 to -0.63; P<0.001). Results from the present meta-analysis suggest that breathing exercises may significantly improve post-operative pulmonary function and QOL in patients with lung cancer.

    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.

    Oral function with removable dentures is improved when dental implants are used for support. A variety of methods is used to measure change in masticatory performance, bite force, patient's satisfaction and nutritional state. A systematic review describing the outcome of the various methods to assess patients' appreciation has not been reported. The objective is to systematically review the literature on the possible methods to measure change in masticatory performance, bite force, patient's satisfaction and nutritional state of patients with removable dentures and to describe the outcome of these. Medline, Embase and The Cochrane Central Register of Controlled Trials were searched (last search July 1, 2014). The search was completed by hand to identify eligible studies. Two reviewers independently assessed the articles. Articles should be written in English. Study design should be prospective. The outcome should be any assessment of function/satisfaction before and at least 1 year after treatment. Study population should consist of fully edentulous subjects. Treatment should be placement of any kind of root-form implant(s) to support a mandibular and/or maxillary overdenture. Fifty-three of 920 found articles fulfilled the inclusion criteria. A variety of methods was used to measure oral function; mostly follow-up was 1 year. Most studies included mandibular overdentures, three studies included maxillary overdentures. Implant-supported dentures were accompanied by high patient's satisfaction with regard to denture comfort, but this high satisfaction was not always accompanied by improvement in general quality of life (QoL) and/or health-related QoL. Bite force improved, masseter thickness increased and muscle activity in rest decreased. Patients could chew better and eat more tough foods. No changes were seen in dietary intake, BMI and blood markers. Improvements reported after 1 year apparently decreased slightly with time, at least on the long run. Treating

    Neodymium yttrium-aluminium-garnet (Nd : YAG) laser resection is one of the mostly used interventional pulmonology techniques for urgent desobstruction of malignant central airway obstruction (CAO). The major aim of this trial was to evaluate potential influence of Nd : YAG laser resection on overall quality of life (QoL) in patients with central lung cancer. Patients with malignant CAO scheduled for Nd : YAG laser resection were prospectively recruited in the trial. All patients were given European Organization for Research and Treatment, Quality of Life questionnaire (EORTC QLQ-30 v.3) before the procedure and approximately 2 weeks after the treatment. There were 37 male and 10 female patients, average age 54 ± 10 years. Most common tumour type was adenocarcinoma diagnosed in 51% of patients. Majority of patients were diagnosed in stage IIIB (53.2%) and stage IV (25.5%). Most common Eastern Cooperative Oncology Group performance status was 1 (72.3%). Nd : YAG laser resection significantly improved (Plife, social activities and financial situation, we did not observe statistically significant improvement. Nd : YAG laser resection of malignant CAO significantly improves QoL and overall health in patients with lung cancer.

    Full Text Available Abstract Background Quality of life (QoL decreases as heart failure worsens, which is one of the greatest worries of these patients. Physical exercise has been shown to be safe for people with heart failure. Previous studies have tested heterogeneous exercise programs using different QoL instruments and reported inconsistent effects on QoL. The aim of this study is to evaluate the effectiveness of a new exercise program for people with heart failure (EFICAR, additional to the recommended optimal treatment in primary care, to improve QoL, functional capacity and control of cardiovascular risk factors. Methods/Design Multicenter clinical trial in which 600 patients with heart failure in NYHA class II-IV will be randomized to two parallel groups: EFICAR and control. After being recruited, through the reference cardiology services, in six health centres from the Spanish Primary Care Prevention and Health Promotion Research Network (redIAPP, patients are followed for 1 year after the beginning of the intervention. Both groups receive the optimized treatment according to the European Society of Cardiology guidelines. In addition, the EFICAR group performs a 3 month supervised progressive exercise program with an aerobic (high-intensity intervals and a strength component; and the programme continues linked with community resources for 9 months. The main outcome measure is the change in health-related QoL measured by the SF-36 and the Minnesota Living with Heart Failure Questionnaires at baseline, 3, 6 and 12 months. Secondary outcomes considered are changes in functional capacity measured by the 6-Minute Walking Test, cardiac structure (B-type natriuretic peptides, muscle strength and body composition. Both groups will be compared on an intention to treat basis, using multi-level longitudinal mixed models. Sex, age, social class, co-morbidity and cardiovascular risk factors will be considered as potential confounding and predictor variables. Discussion

  7. Long-Term Alendronate Use Not without Consequences?

    2009-01-01

    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 According to WHO reports Hepatocellular carcinoma remains an Asian health problem. Its prevalence disproportionately shares large of the world's nearly 78%. Treatment options of HCC are limited and the effectiveness of treatment varies due to development of therapy-related adverse effects in Allopathic medicine. We report herein a case of HCC admitted to Sir Sundarlal Hospital, Banaras Hindu University, Varanasi was treated with integrated Ayurvedic herbo – mineral medicine, with desirable results of improvement in QoL. The patient was treated with a holistic inter disciplinary approach i.e., Modern medicine treatment followed by Ayurveda, health education for cancer care and psychotherapeutic measures such as Yoga, psychological counseling etc. The symptoms were managed according to its clinical presentation and daily clinical evaluation. This paper demonstrates the findings of our experience in treating a case of HCC with Ayurvedic herbo mineral medicine as an adjuvant treatment for improvement of QoL. Moreover, it emphasized the needs to be explored Ayurvedic cancer management with more advance methodology.

    Full Text Available Traditional steel ties reinforcement cannot provide superior confinement for reinforced concrete (RC columns due to the constraints on tie spacing and disturbance of concrete continuity. This paper presents a practical confinement configuration consisting of single Expanded Metal Mesh (EMM layer in additional to regular tie reinforcement. The EMM layer is warped above ties. The proposed transverse reinforcement, with various volumetric ratios of ties, was investigated in sixteen square short RC column specimens categorized in two groups according to their slenderness ratios. The specimens were cast in vertical position simulating the construction field and they were tested under concentric compression till failure. The results indicated that the columns, confined with proposed lateral reinforcement, revealed significant improvement in the strength and ductility. Also, high reduction in ties volumetric ratio with no loss in ultimate load could be achieved by installing the EMM layer.

  11. Strengthening exercises improve symptoms and quality of life but do not change autonomic modulation in fibromyalgia: a randomized clinical trial.

    Maria Bernadete Renoldi Oliveira Gavi

    Full Text Available OBJECTIVE: Autonomic dysfunction is an important mechanism that could explain many symptoms observed in fibromyalgia (FM. Exercise is an effective treatment, with benefits potentially mediated through changes in autonomic modulation. Strengthening is one of the less studied exercises in FM, and the acute and chronic effects of strengthening on the autonomic system remain unknown. The objective of this study was to assess the chronic effects of strengthening exercises (STRE on autonomic modulation, pain perception and the quality of life (QOL of FM patients. METHODS: Eighty sedentary women with FM (ACR 1990 were randomly selected to participate in STRE or flexibility (FLEX exercises in a blinded controlled trial. The intensity of STRE was set at 45% of the estimated load of 1 Repetition Maximum (RM in 12 different exercises. Outcomes were Visual Analog Scale (VAS for pain, Heart Rate Variability (HRV analysis, treadmill test, the sit and reach test (Wells and Dillon's Bench, maximal repetitions test and handgrip dynamometry; and quality of life by the Fibromyalgia Impact Questionnaire (FIQ, the Beck and Idate Trait-State Inventory (IDATE, a short-form health survey (SF-36. RESULTS: The STRE group was more effective to strength gain for all muscles and pain control after 4 and 16 weeks (p<0.05. The FLEX group showed higher improvements in anxiety (p<0.05. Both groups showed improvements in the QOL, and there was no significant difference observed between the groups. There was no change in the HRV of the STRE and FLEX groups. CONCLUSIONS: Strengthening exercises show greater and more rapid improvements in pain and strength than flexibility exercises. Despite the benefits in fitness, pain, depression, anxiety and quality of life, no effect was observed on the autonomic modulation in both groups. This observation suggests that changes in autonomic modulation are not a target tobe clinically achieved in fibromyalgia. TRIAL REGISTRATION: Clinical

    Bariatric surgery is often pursued to improve quality of life (QOL). This paper systematically reviews the literature examining QOL following bariatric surgery. Fifteen controlled trials examined changes in QOL in obese (BMI > 30) adults (18–65 years) following bariatric surgery; seven compared bariatric surgery to non-surgical interventions and six compared different types of bariatric surgery. Bariatric surgery resulted in greater improvements in QOL than other obesity treatments. Significant differences in QOL improvements were found between different types of bariatric surgery. QOL improvements were more likely to occur within the first 2 years following surgery, with greater improvements in physical QOL than mental QOL. Bariatric surgery improves QOL. Future research is needed to investigate changes in QOL in different domains in the short- and long-term following bariatric surgery.

    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.

    Full Text Available Problem statement: The social demands for the Quality Of Life (QOL are increasing with the exponentially expanding silver generation. To improve the QOL of the disabled and elderly people, robotic researchers and biomedical engineers have been trying to combine their techniques into the rehabilitation systems. Various biomedical signals (biosignals acquired from a specialized tissue, organ, or cell system like the nervous system are the driving force for the entire system. Examples of biosignals include Electro-Encephalogram (EEG, Electrooculogram (EOG, Electroneurogram (ENG and (EMG. Approach: Among the biosignals, the research on EMG signal processing and controlling is currently expanding in various directions. EMG signal based research is ongoing for the development of simple, robust, user friendly, efficient interfacing devices/systems for the disabled. The advancement can be observed in the area of robotic devices, prosthesis limb, exoskeleton, wearable computer, I/O for virtual reality games and physical exercise equipments. An EMG signal based graphical controller or interfacing system enables the physically disabled to use word processing programs, other personal computer software and internet. Results: Depending on the application, the acquired and processed signals need to be classified for interpreting into mechanical force or machine/computer command. Conclusion: This study focused on the advances and improvements on different methodologies used for EMG signal classification with their efficiency, flexibility and applications. This review will be beneficial to the EMG signal researchers as a reference and comparison study of EMG classifier. For the development of robust, flexible and efficient applications, this study opened a pathway to the researchers in performing future comparative studies between different EMG classification methods.

    Full Text Available Abstract Background Chronic congestive heart failure (CHF is a complex disease with rising prevalence, compromised quality of life (QoL, unplanned hospital admissions, high mortality and therefore high burden of illness. The delivery of care for these patients has been criticized and new strategies addressing crucial domains of care have been shown to be effective on patients' health outcomes, although these trials were conducted in secondary care or in highly organised Health Maintenance Organisations. It remains unclear whether a comprehensive primary care-based case management for the treating general practitioner (GP can improve patients' QoL. Methods/Design HICMan is a randomised controlled trial with patients as the unit of randomisation. Aim is to evaluate a structured, standardized and comprehensive complex intervention for patients with CHF in a 12-months follow-up trial. Patients from intervention group receive specific patient leaflets and documentation booklets as well as regular monitoring and screening by a prior trained practice nurse, who gives feedback to the GP upon urgency. Monitoring and screening address aspects of disease-specific self-management, (nonpharmacological adherence and psychosomatic and geriatric comorbidity. GPs are invited to provide a tailored structured counselling 4 times during the trial and receive an additional feedback on pharmacotherapy relevant to prognosis (data of baseline documentation. Patients from control group receive usual care by their GPs, who were introduced to guideline-oriented management and a tailored health counselling concept. Main outcome measurement for patients' QoL is the scale physical functioning of the SF-36 health questionnaire in a 12-month follow-up. Secondary outcomes are the disease specific QoL measured by the Kansas City Cardiomyopathy questionnaire (KCCQ, depression and anxiety disorders (PHQ-9, GAD-7, adherence (EHFScBS and SANA, quality of care measured by an adapted

  20. Leg Lengthening as a Means of Improving Ambulation Following an Internal Hemipelvectomy

    2016-01-01

    Full Text Available Reconstructive surgery following an internal hemipelvectomy for a malignant pelvic tumor is difficult due to the structural complexity of the pelvis and the massive extension of the tumor. While high complication rates have been encountered in various types of reconstructive surgery, resection without reconstruction reportedly involved fewer complications. However, this method often results in limb shortening with resultant instability during walking. We reported herein leg lengthening performed to correct lower limb shortening after an internal hemipelvectomy, which improved ambulatory stability and overall QOL. An 18-year-old male patient came to our hospital to correct a lower limb discrepancy resulting from a left internal hemipelvectomy. His left pelvis and proximal femur had been resected, and the femur remained without an acetabular roof. His left lower limb was about 8 centimeters shorter. The left tibia was lengthened 8 centimeters with an external fixator. After the lengthening, the patient was able to walk without support and his gait remarkably improved. Additionally he no longer required placing a wallet in his back pocket as a pad as a means of raising the left side of his torso while sitting. Leg lengthening was a useful method of improving ambulation after an internal hemipelvectomy.

    Full Text Available AIM The purpose of this study was to describe of life-style modifiying education and counseling to examine their effect on renal function and quality of life. 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.

    The objective of this study was to investigate the significance of changes from the standard dosing schedule of sunitinib, which is 4 weeks of treatment and 2 weeks off (schedule 4/2), to an alternative schedule with 2 weeks of treatment and 1 week off (schedule 2/1), after encountering dose-limiting toxicity in 45 consecutive Japanese patients with metastatic renal cell carcinoma (mRCC). Despite a definitively improved relative dose intensity of sunitinib by changing from schedule 4/2 to 2/1, this difference was not significant. Adverse events (AEs) occurred in all patients on both schedules 4/2 and 2/1; however, the proportion of patients experiencing AEs ≥ grade 3 on schedule 2/1 was significantly lower than that on schedule 4/2. Quality of life (QOL) analysis using SF-36 revealed that all eight scores during schedule 2/1 were more favorable than those during schedule 4/2, and there were significant differences in 2 of the 8 scores between these two schedules. Furthermore, multivariate analyses, which were performed to evaluate the contribution of several AEs on schedule 2/1 to the improvement of each score in SF-36, revealed that fatigue had independent impacts on two scores, despite the lack of an independent association between any scores and the remaining AEs examined. These findings suggest that schedule 2/1 is the optimal dosing schedule of sunitinib against mRCC that balances efficacy and toxicity, since treatment on schedule 2/1 resulted in a markedly improved QOL compared with that on schedule 4/2 by relieving the profile of sunitinib-related AEs.

    Objectives. To compare the effectiveness of real acupressure versus sham acupressure therapy in improving sleep quality in patients receiving hemodialysis (HD) or hemodiafiltration (HDF). Methods. A multicenter, single-blind, randomized controlled trial was conducted in two Australian dialysis units located in Princess Alexandra Hospital and Logan Hospital, respectively. Forty-two subjects with self-reported poor sleep quality were randomly assigned to real (n = 21) or sham (n = 21) acupressure therapy delivered thrice weekly for four consecutive weeks during routine dialysis sessions. The primary outcome was the Pittsburgh Sleep Quality Index (PSQI) score measured at week four adjusted for baseline PSQI measurements. Secondary outcomes were quality of life (QOL) (SF-8), adverse events, and patient acceptability (treatment acceptability questionnaire, TAQ). Results. The two groups were comparable on global PSQI scores (difference 0.19, 95% confidence interval [CI] −1.32 to 1.70) and on the subscale scores. Similar results were observed for QOL both in the mental (difference −3.88, 95% CI −8.63 to 0.87) and the physical scores (difference 2.45, 95% CI −1.69 to 6.58). There were no treatment-related adverse events and acupressure was perceived favorably by participants. Conclusion. Acupressure is a safe, well-tolerated, and highly acceptable therapy in adult hemodialysis patients in a Western healthcare setting with uncertain implications for therapeutic efficacy.

    Full Text Available Abstract Background Fibromyalgia engulfs patients in a downward, reinforcing cycle of unrestorative sleep, chronic pain, fatigue, inactivity, and depression. In this study we tested whether a mostly raw vegetarian diet would significantly improve fibromyalgia symptoms. Methods Thirty people participated in a dietary intervention using a mostly raw, pure vegetarian diet. The diet consisted of raw fruits, salads, carrot juice, tubers, grain products, nuts, seeds, and a dehydrated barley grass juice product. Outcomes measured were dietary intake, the fibromyalgia impact questionnaire (FIQ, SF-36 health survey, a quality of life survey (QOLS, and physical performance measurements. Results Twenty-six subjects returned dietary surveys at 2 months; 20 subjects returned surveys at the beginning, end, and at either 2 or 4 months of intervention; 3 subjects were lost to follow-up. The mean FIQ score (n = 20 was reduced 46% from 51 to 28. Seven of the 8 SF-36 subscales, bodily pain being the exception, showed significant improvement (n = 20, all P for trend Conclusion This dietary intervention shows that many fibromyalgia subjects can be helped by a mostly raw vegetarian diet.

    2011-12-01

    The year 2011 was declared the 'European Year of Volunteering' to recognise the contribution volunteers make to society. Such cross-national events reflect the high profile of volunteering and political imperatives to promote it. The purpose of this review is to provide a comprehensive review of current knowledge (articles published between 2005 and 2011) regarding the role of volunteering in improving older people's quality of life (QoL) and to identify areas requiring further research. Volunteering was defined as an activity that is freely chosen, does not involve remuneration and helps or benefits those beyond an individual's immediate family. Our search identified 22 studies and 5 review articles that addressed the benefits of volunteering on older people's quality of life. Most of the research had been conducted in the United States, Canada and Australia using data from longitudinal studies. The majority of the studies concluded that there is a positive association between older people's quality of life and engagement in volunteering. Due to the study designs and the heterogeneity of the research, causality is difficult to demonstrate and the knowledge the studies bring to the subject is variable. This review shows that volunteering may help to maintain and possibly improve some older adults' quality of life. However, there are still major gaps in our understanding of who actually benefits, the social and cultural context of volunteering and its role in reducing health and social inequalities.

    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 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 Abstract Background Although previous research has demonstrated that referral to pre-dialysis clinics is associated with favourable objective outcomes, the benefit of a pre-dialysis clinic from the perspective of patient-perceived subjective outcomes, such as quality of life (QOL, is less well defined. Methods A retrospective incident cohort study was conducted to determine if pre-dialysis clinic attendance was a predictor of better QOL scores measured within the first six months of hemodialysis (HD initiation. Inclusion criteria were HD initiation from January 1 1998 to January 1 2000, diagnosis of chronic renal failure, and completion of the QOL questionnaire within six months of HD initiation. Patients receiving HD for less than four weeks were excluded. An incident cohort of 120 dialysis patients was identified, including 74 patients who attended at least one pre-dialysis clinic and 46 patients who did not. QOL was measured using the SF 36-Item Health Survey. Independent variables included age, sex, diabetes, pre-dialysis clinic attendance and length of attendance, history of ischemic heart disease, stroke, peripheral vascular disease, heart failure, malignancy, and chronic lung disease, residual creatinine clearance at dialysis initiation, and kt/v, albumin and hemoglobin at the time of QOL assessment. Bivariate and multivariate linear regression analyses were used to identify predictors of QOL scores.

    Objective: The aim of this study is to compare a cognitive behavioral group therapy (CBT) with a health enhancement program (HEP) for stress reduction and the impact on quality of life (QoL) in patients with Parkinson’s disease (PD). Method: Thirty patients with PD participated in the study: 16 received CBT including stress-reducing elements and 14 took part in a HEP. The two groups did not differ significantly in their baseline demographic characteristics. The patients in both groups underwent weekly sessions of 2 h duration for 9 weeks. The Parkinson’s Disease Questionnaire with 39 items (PDQ-39), the Burden Questionnaire for Parkinson’s Disease (translated from the original German: Belastungsfragebogen für Parkinsonpatienten (BELA) and the Disease-Related Questionnaire [Fragebogen zur krankheitsbezogenen Kommunikation (FKK)] were used for assessment. Ratings were completed at baseline and after 9 weeks (immediately after the last treatment session). Results: The patients in the CBT group achieved significantly better BELA, FKK and PDQ-39 scores (p < 0.05). Subscale analysis revealed that the scores on the BELA subscales “emotional well-being” and “somatic motor function” contributed significantly to stress reduction (p < 0.05). The FKK revealed significant improvement in social skills in the CBT group (p < 0.05). Conclusion: Cognitive Behavioral Group Therapy appears to be an effective way for patients with PD to lessen stress and improve their quality of life. PMID:28101066

    2012-01-01

    Full Text Available Abstract Background Self-rated Health (SRH and health-related quality of life (HRQoL are used to evaluate health disparities. Like all subjective measures of health, they are dependent on health expectations that are associated with socioeconomic characteristics. It is thus needed to analyse the influence played by socioeconomic position (SEP on the relationship between these two indicators and health conditions if we aim to use them to study health disparities. Our objective is to assess the influence of SEP on the relationship between physical health status and subjective health status, measured by SRH and HRQoL using the SF-36 scale. Methods We used data from the French National Health Survey. SEP was assessed by years of education and household annual income. Physical health status was measured by functional limitations and chronic low back pain. Results Regardless of their health status, people with lower SEP were more likely than their more socially advantaged counterparts to report poor SRH and poorer HRQoL, using any of the indicators of SEP. The negative impact of chronic low back pain on SRH was relatively greater in people with a high SEP than in those with a low SEP. In contrast, chronic low back pain and functional limitations had less impact on physical and mental component scores of quality of life for socially advantaged men and women. Conclusions Both SRH and HRQoL were lower among those reporting functional limitations or chronic low back pain. However, the change varied according SEP and the measure. In relative term, the negative impact of a given health condition seems to be greater on SRH and lower on HRQoL for people with higher SEP in comparison with people with low SEP. Using SRH could thus decrease socioeconomic differences. In contrast using HRQoL could increase these differences, suggesting being cautious when using these indicators for analyzing health disparities.

    The aim of this study is to clarify the associations between diurnal blood pressure variation, physical activity and health-related quality of life (HRQOL). Ninety-seven volunteers, including 52 hypertensive patients and 45 healthy subjects (average age, 48 years) participated in this study. Twenty-four hour ambulatory blood pressure and heart rate variability were measured using TM2425 (A&D Co). Physical activity was measured using actigraphy, and HRQOL was assessed by a Medical Outcome Study Short-Forum 36-Item Health Survey (SF-36). Awake mean physical activity positively correlated with the nocturnal dip in systolic blood pressure (SBP) (r = 0.242, p physical functioning positively correlated with awake mean physical activity (r = 0.265, p physical activity (r = 0.269, p = 0.01). Using multiple regression analysis, the nocturnal dip in SBP was found to be correlated with awake and sleep mean physical activities (p physical activity is associated with the nocturnal dip in blood pressure. Moreover, physical activity correlates with some of the factors of HRQOL.

One month after the start of oral administration of alendronate (35 mg per week, his bone pain had fallen from a visual analog scale score of 83 out of 100 to 30 out of 100 and, at nine months, was further reduced to 3 out of 100. The treatment was discontinued at 15 months because of successful pain reduction. At 30 months, our patient had no pain and the radiographic findings revealed marked improvement in regional osteoporotic changes. Conclusions We believe low-dose oral administration of bisphosphonate is worth considering for the treatment of idiopathic complex regional pain syndrome type I accompanied by regional osteoporotic change.

    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.

    Full Text Available Abstract Background 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. Methods 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. Results 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. Conclusion We conclude that this treatment is well tolerated, with an encouraging objective response rate, and a significant improvement in quality of life (p

    Types in programming languages provide a powerful tool for the programmer to document the code so that a large aspect of the intent can not only be presented to fellow programmers but also be checked automatically by compilers. The precision with which types model the behavior of programs...... is crucial to the quality of these automated checks, and in this thesis we present three different improvements to the precision of types in three different aspects of the Java programming language. First we show how to extend the type system in Java with a new type which enables the detection of unintended...... mixing of unrelated types. Secondly, we present an improvement of the type checking algorithm in Java which enables the compiler to detect and ease the use of a common programming idiom called guarded casts. Thirdly, we present an improvement of the precision with which classes generated by a parser...

    As lithium-ion battery technologies mature, the size and energy of these systems continues to increase (> 50 kWh for EVs); making safety and reliability of these high energy systems increasingly important. While most material advances for lithium-ion chemistries are directed toward improving cell performance (capacity, energy, cycle life, etc.), there are a variety of materials advancements that can be made to improve lithium-ion battery safety. Issues including energetic thermal runaway, electrolyte decomposition and flammability, anode SEI stability, and cell-level abuse tolerance continue to be critical safety concerns. This report highlights work with our collaborators to develop advanced materials to improve lithium-ion battery safety and abuse tolerance and to perform cell-level characterization of new materials.

    2009-01-01

    In order to improve the unitarity of the S-matrix, an improved variational formulism is derived by proposing new generating functionals and adopting proper asymptotic boundary conditions for trial relative wave functions. The formulas with the weighted line-column balance for the single-channel and multi-channel scatterings, where the non-central interaction is implicitly considered, are presented. A numerical check is performed with a soluble model in a four coupled channel scattering problem. The result shows that the high accuracy and the unitarity of the S-matrix are reached.

    Nuclear energy already today plays an important role in decarbonisation of the electricity sector while providing energy security and being economically competitive. Nuclear energy is characterized by its very high energy density and is well suited for large-scale, baseload electricity supply. Similar to renewable energy sources such as wind, solar or biomass, nuclear power is characterized by an abundant supply of its primary energy source, uranium, but is not limited to the same extent as these renewable energy sources from being an intermittent energy supply or imposing severe restrictions on land-use. Improving energy efficiency of nuclear power plants has contributed to a better utilization of the uranium resources and has helped improving the economic performance of nuclear power plants. This is to a large degree accomplished through optimisation of nuclear fuel assemblies as well as renewing turbines and generators. More importantly however, the overall economy of nuclear power has improved though better plant management leading to higher capacity factors and by extending the lifetimes of existing nuclear power plants. Provided that improved safety, economics and successful waste management can be demonstrated nuclear power is likely to grow in the future. Non-electricity applications may further boost the growth of nuclear energy, especially with the development of new reactor systems allowing for cogeneration of electricity and hydrogen or biofuels for transport.

    AIM: To assess the safety of enhanced recovery after surgery(ERAS) program in gastrectomy and influences on nutrition state and insulin-resistance. METHODS: Our ERAS program involved shortening the fasting periods and preoperative carbohydrate loading. Eighty gastrectomy patients were randomly assigned to either the conventional group(CG) or ERAS group(EG). We assessed the clinical characteristics and postoperative outcomes prospectively. The primary endpoint was noninferiority in timely discharge from the hospital within 12 d. Secondary endpoints were the incidence of aspiration at anesthesia induction, incidence of postoperative complications, health related quality of life(HRQOL) using the SF8 Health Survey questionnaire, nutrition state [e.g., albumin, transthyretin(TTR), retinal-binding protein(RBP), and transferrin(Tf)], the homeostasis model assessment-insulin resistance(HOMA-R) index, postoperative urine volume,postoperative weight change, and postoperative oral intake.RESULTS: The ERAS program was noninferior to the conventional program in achieving discharge from the hospital within 12 d(95.0% vs 92.5% respectively; 95%CI:-10.0%-16.0%). There was no significant difference in postoperative morbidity between the two groups. Adverse events such as vomiting and aspiration associated with the induction of general anesthesia were not observed. There were no significant differences with respect to postoperative urine volume, weight change, and oral intake between the two groups. EG patients with preoperative HOMA-R scores above 2.5 experienced significant attenuation of their HOMA-R scores on postoperative day 1 compared to CG patients(P = 0.014). There were no significant differences with respect to rapid turnover proteins(TTR, RBP and Tf) or HRQOL scores using the SF8 method.CONCLUSION: Applying the ERAS program to patients who undergo gastrectomy is safe, and improves insulin resistance with no deterioration in QOL.

    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.

    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.

  11. Diversification improves interpolation

    CERN Document Server

    Giesbrecht, Mark

    2011-01-01

    We consider the problem of interpolating an unknown multivariate polynomial with coefficients taken from a finite field or as numerical approximations of complex numbers. Building on the recent work of Garg and Schost, we improve on the best-known algorithm for interpolation over large finite fields by presenting a Las Vegas randomized algorithm that uses fewer black box evaluations. Using related techniques, we also address numerical interpolation of sparse complex polynomials, and provide the first provably stable algorithm (in the sense of relative error) for this problem, at the cost of modestly more interpolation points. A key new technique is a randomization which makes all coefficients of the unknown polynomial distinguishable, producing what we call a diverse polynomial. Another departure of our algorithms from most previous approaches is that they do not rely on root finding as a subroutine. We show how these improvements affect the practical performance with trial implementations.

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 Learning is a lifelong process of transforming information and experience into knowledge, skills, behaviorand attitudes. 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. Apart from the foods, one should keep the brain active to maintain its cognitivefunction well.

  19. Improved flywheel materials :

    Energy Technology Data Exchange (ETDEWEB)

    Boyle, Timothy J.; Bell, Nelson S; Ehlen, Mark Andrew; Anderson, Benjamin John; Miller, William Kenneth

    2013-09-01

    As alternative energy generating devices (i.e., solar, wind, etc) are added onto the electrical energy grid (AC grid), irregularities in the available electricity due to natural occurrences (i.e., clouds reducing solar input or wind burst increasing wind powered turbines) will be dramatically increased. Due to their almost instantaneous response, modern flywheel-based energy storage devices can act a mechanical mechanism to regulate the AC grid; however, improved spin speeds will be required to meet the necessary energy levels to balance these green energy variances. Focusing on composite flywheels, we have investigated methods for improving the spin speeds based on materials needs. The so-called composite flywheels are composed of carbon fiber (C-fiber), glass fiber, and a glue (resin) to hold them together. For this effort, we have focused on the addition of fillers to the resin in order to improve its properties. Based on the high loads required for standard meso-sized fillers, this project investigated the utility of ceramic nanofillers since they can be added at very low load levels due to their high surface area. The impact that TiO2 nanowires had on the final strength of the flywheel material was determined by a three-point-bend test. The results of the introduction of nanomaterials demonstrated an increase in strength of the flywheels C-fiber-resin moiety, with an upper limit of a 30% increase being reported. An analysis of the economic impact concerning the utilization of the nanowires was undertaken and after accounting for new-technology and additional production costs, return on improved-nanocomposite investment was approximated at 4-6% per year over the 20-year expected service life. Further, it was determined based on the 30% improvement in strength, this change may enable a 20-30% reduction in flywheel energy storage cost ($/kW-h).

Las variables recogidas fueron: demograficas, de tratamiento, clinicas y de seguridad. Se considero efectividad del tratamiento al aumento de la densidad mineral osea hasta obtener Z-score > -2,5 DE. Resultados: un total de 12 pacientes, 8 varones, con una media de edad de 11 anos (} 3 DE), fueron tratados con acido alendronico. Tras un tiempo medio de tratamiento de 2,15 anos (} 1,2 DE), se produjo aumento de la densidad mineral osea en todos los pacientes, 9 de los cuales obtuvieron Z-score > -2,5 DE, por lo que el farmaco se considero efectivo en el 75% de los casos. Ningun paciente presento fracturas oseas ni manifesto efectos adversos durante el tratamiento. Conclusiones: el acido alendronico incremento la densidad mineral osea y se tolero bien en todos los pacientes, por lo que se podria considerar como opcion terapeutica en el tratamiento de la osteoporosis infantil.

  3. Deceleration Orbit Improvements

    1991-04-26

    During the accelerator studies period of 12/90-1/91 much study time was dedicated to improving the E760 deceleration ramps. 4 general goals were in mind: (1) Reduce the relative orbit deviations from the nominal reference orbit as much as possible. This reduces the potential error in the orbit length calculation - which is the primary source of error in the beam energy calculation. (2) Maximize the transverse apertures. This minimizes beam loss during deceleration and during accidental beam blow-ups. (3) Measure and correct lattice parameters. Knowledge of {gamma}{sub T}, {eta}, Q{sub h}, Q{sub v}, and the dispersion in the straight sections allows for a more accurate energy calculation and reliable SYNCH calculations. (4) Minimize the coupling. This allows one to discern between horizontal and vertical tunes.

    As we have shown above, wind energy can help to secure energy efficiency in power generation, and research results and tools are being developed that will increase the role of wind energy in the global energy supply. An important instrument is the development of wind turbine technology to reduce capital and operational costs. This has not been the emphasis in this chapter, though; instead we have focused on equally important instruments, namely making best use of the wind resource and available sites, adapting wind farm layout and technology to the increased exploitation of wind, and improving the interaction between wind farms and the power system. With these developments we expect that wind energy can become the backbone of the power system globally and play a major role in creating an efficient and sustainable power system. (Author)

    Full Text Available This article investigates the current data management practices of university researchers at an Intermountain West land-grant research university in the United States. Key findings suggest that researchers are primarily focused on the collection and housing of research data. However, additional research value exists within the other life cycle stages for research data—specifically in the stages of delivery and maintenance. These stages are where most new demands and requirements exist for data management plans and policies that are conditional for external grant funding; therefore, these findings expose a “gap” in current research practice. These findings should be of interest to academics and practitioners alike as findings highlight key management gaps in the life cycle of research data. This study also suggests a course of action for academic institutions to coalesce campus-wide assets to assist researchers in improving research value.

  7. Improved Lattice Radial Quantization

    2014-01-01

    Lattice radial quantization was proposed in a recent paper by Brower, Fleming and Neuberger[1] as a nonperturbative method especially suited to numerically solve Euclidean conformal field theories. The lessons learned from the lattice radial quantization of the 3D Ising model on a longitudinal cylinder with 2D Icosahedral cross-section suggested the need for an improved discretization. We consider here the use of the Finite Element Methods(FEM) to descretize the universally-equivalent $\\phi^4$ Lagrangian on $\\mathbb R \\times \\mathbb S^2$. It is argued that this lattice regularization will approach the exact conformal theory at the Wilson-Fisher fixed point in the continuum. Numerical tests are underway to support this conjecture.

    The 2015 Institute of Medicine report on diagnostic error has placed a national spotlight on the importance of improving communication among clinicians and between clinicians and patients [1]. The report emphasizes the critical role that communication plays in patient safety and outlines ways that pathologists can support this process. Despite recognition of communication as an essential element in patient care, pathologists currently undergo limited (if any) formal training in communication skills. To address this gap, we at the University of Washington Medical Center developed communication training with the goal of establishing best practice procedures for effective pathology communication. The course includes lectures, role playing, and simulated clinician-pathologist interactions for training and evaluation of pathology communication performance. Providing communication training can help create reliable communication pathways that anticipate and address potential barriers and errors before they happen.

    Full Text Available Abstract Background With current treatments, approximately 75% of children diagnosed with cancer can expect to achieve disease-free survival. However, treatments are complex and aggressive, potentially compromising QOL for children and their parents. Although previous work has shown increased anxiety and depression among parents after diagnosis, the recent development of standardised measures of QOL enables us to look more directly at the impact of diagnosis on mothers' and children's QOL. The aims of this study are to i describe QOL for children and their mothers after diagnosis by comparing their scores with population norms, ii explore the relationship between mothers' worries about the illness and their QOL, and iii determine the relationship between mothers ratings of their own QOL and their child. Method A total of 87 families took part, constituting 60% of those eligible. The children included 58 males and 29 females aged between 2 years 6 months to 16 years 3 months (mean = 7 years, median = 5 years 8 months. Diagnoses were acute lymphoblastic leukaemia (ALL, n = 57, brain tumours (n = 11, bone tumours (n = 17 and 2 rare cancers. Mothers completed questionnaires about their own and the child's QOL. Results Mothers' reported their own and the child's QOL to be significantly lower than population norms. There were significant correlations between mothers' worries and their own and their ratings of the child's QOL and mothers' ratings of their own QOL correlated with their ratings of the child's QOL. Conclusion Both children and their mothers experience significantly compromised QOL in the months following diagnosis. Mothers who rated their own QOL to be poor also rate their child's QOL to be low. These results suggest caution is required where mothers rate their child's QOL. Efforts must continue to be made to improve QOL of children especially in the period immediately following diagnosis.

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

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.

    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

  17. Refines Efficiency Improvement

    Refinery processes that convert heavy oils to lighter distillate fuels require heating for distillation, hydrogen addition or carbon rejection (coking). Efficiency is limited by the formation of insoluble carbon-rich coke deposits. Heat exchangers and other refinery units must be shut down for mechanical coke removal, resulting in a significant loss of output and revenue. When a residuum is heated above the temperature at which pyrolysis occurs (340 C, 650 F), there is typically an induction period before coke formation begins (Magaril and Aksenova 1968, Wiehe 1993). To avoid fouling, refiners often stop heating a residuum before coke formation begins, using arbitrary criteria. In many cases, this heating is stopped sooner than need be, resulting in less than maximum product yield. Western Research Institute (WRI) has developed innovative Coking Index concepts (patent pending) which can be used for process control by refiners to heat residua to the threshold, but not beyond the point at which coke formation begins when petroleum residua materials are heated at pyrolysis temperatures (Schabron et al. 2001). The development of this universal predictor solves a long standing problem in petroleum refining. These Coking Indexes have great potential value in improving the efficiency of distillation processes. The Coking Indexes were found to apply to residua in a universal manner, and the theoretical basis for the indexes has been established (Schabron et al. 2001a, 2001b, 2001c). For the first time, a few simple measurements indicates how close undesired coke formation is on the coke formation induction time line. The Coking Indexes can lead to new process controls that can improve refinery distillation efficiency by several percentage points. Petroleum residua consist of an ordered continuum of solvated polar materials usually referred to as asphaltenes dispersed in a lower polarity solvent phase held together by intermediate polarity materials usually referred to as

    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.

    We tried to improve the materials and methods of high-dose rate Iridium-192 brachytherapy for localized prostate cancer and evaluated the stress during the treatment in 20 patients with whom the therapy was performed. 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.

    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.

    Randall S. Seright

    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

    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

    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.

    Objectives The olfactory function highly impacts quality of life (QoL). Continuous positive airway pressure is an effective treatment for obstructive sleep apnea (OSA) and is often applied by nasal masks (nCPAP). The influence of nCPAP on the olfactory performance of OSA patients is unknown. The aim of this study was to assess the sense of smell before initiation of nCPAP and after three months treatment, in moderate and severe OSA patients. Methods The sense of smell was assessed in 35 patients suffering from daytime sleepiness and moderate to severe OSA (apnea/hypopnea index ≥ 15/h), with the aid of a validated test battery (Sniffin’ Sticks) before initiation of nCPAP therapy and after three months of treatment. Additionally, adherent subjects were included in a double-blind randomized three weeks CPAP-withdrawal trial (sub-therapeutic CPAP pressure). Results Twenty five of the 35 patients used the nCPAP therapy for more than four hours per night, and for more than 70% of nights (adherent group). The olfactory performance of these patients improved significantly (p = 0.007) after three months of nCPAP therapy. When considering the entire group of patients, olfaction also improved significantly (p = 0.001). In the randomized phase the sense of smell of six patients deteriorated under sub-therapeutic CPAP pressure (p = 0.046) whereas five patients in the maintenance CPAP group showed no significant difference (p = 0.501). Conclusions Olfactory performance improved significantly after three months of nCPAP therapy in patients suffering from moderate and severe OSA. It seems that this effect of nCPAP is reversible under sub-therapeutic CPAP pressure. Trial registration ISRCTN11128866 PMID:28158212

    2014-07-01

    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.

    A variety of surface modifications have been tested for the enhancement of screw fixation in bone, and locally delivered anti-osteoporosis drugs such as bisphosphonates (BP) are then of interest. In this in vivo study, the impact of surface immobilized BP was compared with systemic BP delivery and screws with no BP. After due in vitro characterization, differently treated stainless steel (SS) screws were divided into four groups with 10 rats each. Three of the groups received screws coated with sol-gel derived TiO(2) and calcium phosphate (SS+TiO(2)+CaP). One of these had no further treatment, one had alendronate (BP) adsorbed to calcium phosphate mineral, and one received systemic BP treatment. The fourth group received uncoated SS screws and no BP (control). The screw pullout force was measured after 4 weeks of implantation in rat tibiae. The immobilized amount and release rate of alendronate could be controlled by different immersion times. The SS+TiO(2)+CaP coating did not increase the pullout force compared to SS alone. Surface delivered alendronate enhanced the pullout force by 93% [p = 0.000; 95% Confidence Interval (CI): 67-118%] compared to SS, and by 39% (p = 0.044; 95% CI: 7-71%) compared to systemic alendronate delivery. Both surface immobilized and systemically delivered alendronate improved implant fixation. Also, locally delivered, that is, surface immobilized alendronate showed a better fixation than systemically delivered. Using sol-gel derived TiO(2) as a platform, it is possible to administer controllable amounts of a variety of BPs.

    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.

    Northsea, C

    1996-12-01

    Opportunities for improvements in patient outcomes through applied continuous quality improvement (CQI) programs are endless and exciting. Improving vascular access outcomes has been a long-standing clinical problem for hemodialysis patients and the nephrology team. During the past few years there has been a dramatic increase in the use of dialysis catheters as permanent accesses for hemodialysis patients. All hemodialysis with dialysis catheters are at risk for catheter occlusion. An innovative, 2-year CQI program was developed, implemented, and designed to improve dialysis catheter patency rates with the use of urokinase. The CQI program resulted in a number of clinical outcomes that were beneficial to the patients and dialysis staff, and were cost-effective to the program.

  5. Improving self-esteem by improving physical attractiveness.

    Patzer, G L

    1997-01-01

    Many characteristics comprise a person's personality: achievement orientation, interest to be sociable, aggressiveness, need for order, disposition, and so on. One of the most important personality characteristics in every person's life is self-esteem, which can be defined in terms of cognitive generalizations derived from past experiences. Since people are not isolated from their environment, a person's experiences impact his or her self-esteem. Since a person's physical attractiveness is known to be a major factor in his or her experiences, it is logical (as well as empirically documented) to be a substantial influence on self-esteem. The research shows that improving a physical trait improves attitude, personality, and self-esteem. Likewise, improving physical attractiveness improves interpersonal interactions. These more positive interactions are internalized intrapersonally (within a person), with direct, corresponding impact on the person's self-esteem.

  7. Lessons Learned on Stage: How Improv Can Improve Science Communication

    Wong, G. J.; Kohn, C.; McPeek, M. A.; Serrell, N.

    2014-12-01

    A challenge facing STEM graduate students is the daunting task of communicating their research to a non-specialist audience. Strategies that work well in lab group meetings, such as using acronyms and jargon, do not work in the real world. Ideally, scientists should directly connect with any audience, responding spontaneously and actively, distilling their messages into conversational morsels that resonate with that audience. Scientists should listen. This presentation highlights a 10-week, interdisciplinary graduate course at Dartmouth College that teaches methods for communicating science with clarity, vividness, and emotion. The course was developed in partnership with Stony Brook University's Alan Alda Center for Communicating Science, and emphasizes story-telling, two-way communication, active listening, and so much more. Effective message development and communication skills - spontaneity, authenticity, and connectivity - are honed through improvisational theater exercises. One might ask, "why improv?" As a co-developer/co-instructor of this graduate course and a Ph.D. candidate in Earth Sciences, my response is, "why not improv?" Improv is acting without a script. It is also underground rap battles, baking from scratch, and playing jazz flute. Improv is Macguyver. Improv is not any one particular thing so much as it is a process through which we do things. Improv can teach us a lot: how to play, how to feel comfortable and present even while flailing, and how to truly listen.

    Introduction Health-related quality of life (HRQOL) is affected by numerous clinical variables, including disease activity, damage, fibromyalgia, depression and anxiety. However, these associations have not yet been described in Mexican patients with systemic lupus erythematosus (SLE). Objective To evaluate the relationship between disease activity, damage, depression and fibromyalgia and HRQOL measured by the LupusQoL-instrument in Mexican patients with SLE. Methods A cross-sectional study was conducted in women fulfilling the 1997 ACR classification criteria for SLE. HRQOL was evaluated using a disease-specific instrument for SLE, the LupusQoL (validated for the Spanish-speaking population). Patients were evaluated clinically to determine the degree of disease activity and damage using the Mexican Systemic Lupus Erythematosus Disease Activity Index (Mex-SLEDAI) and Systemic Lupus International Collaborating Clinics-Damage Index (SLICC), respectively. Fibromyalgia and depression were assessed using the ACR criteria and the CES-D scale, respectively. The relationship between HRQOL and these variables was measured using Spearman’s rank correlation coefficient and linear regression analysis. Results A total of 138 women with SLE, age 40.3±11 years, disease duration 8.8±6.4 years, with disease activity in 51.4%, depression in 50%, damage in 43% and fibromyalgia in 19.6% were included. Poorer HRQOL correlated with depression (r = -0.61; p< 0.005), fibromyalgia (r = -0.42; p< 0.005), disease activity (r = -0.37; p < 0.005) and damage (r = -0.31; p < 0.005). In the multivariate linear regression analysis, damage (β = -3.756, p<0.005), fibromyalgia (β = -0.920, p<0.005), depression (β = -0.911, p<0.005) and disease activity (β = -0.911, p<0.005) were associated with poor HRQOL. Conclusion SLE disease activity, damage, fibromyalgia and depression were associated with poor HRQOL in our sample of Mexican SLE patients. PMID:28114336

We therefore investigated the validity of the Chinese (Singapore version of EQ-VAS in patients with diabetes. Methods In a cross-sectional survey, patients with type 2 diabetes seen in a primary care facility completed an identical Chinese or English questionnaire containing the EQ-5D-3L and questions assessing other health and disease-related characteristics. Convergent and known-groups validity of the EQ-VAS was examined for Chinese- and English-speaking respondents separately. Results The EQ-VAS was correlated with the EQ-5D-3L health index and a 5-point Likert-type scale for assessing global health in both Chinese-speaking (N = 335 and English-speaking respondents (N = 298, suggesting convergent validity. The mean EQ-VAS scores differed between English-speaking patients with differing duration of diabetes ( Conclusions Chinese- and English-speaking Singaporeans respond differently to the EQ-VAS. The Chinese version of EQ-VAS appears less sensitive than its English version for measuring global health in patient populations in Singapore.

    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.

    The term "lean production," also known as "Lean," describes a process of operations management pioneered at the Toyota Motor Company that contributed significantly to the success of the company. Although developed by Toyota, the Lean process has been implemented at many other organizations, including those in health care, and should be considered by dental schools in evaluating their clinical operations. Lean combines engineering principles with operations management and improvement tools to optimize business and operating processes. One of the core concepts is relentless elimination of waste (non-value-added components of a process). Another key concept is utilization of individuals closest to the actual work to analyze and improve the process. When the medical center of the University of Kentucky adopted the Lean process for improving clinical operations, members of the College of Dentistry trained in the process applied the techniques to improve inefficient operations at the Walk-In Dental Clinic. The purpose of this project was to reduce patients' average in-the-door-to-out-the-door time from over four hours to three hours within 90 days. Achievement of this goal was realized by streamlining patient flow and strategically relocating key phases of the process. This initiative resulted in patient benefits such as shortening average in-the-door-to-out-the-door time by over an hour, improving satisfaction by 21%, and reducing negative comments by 24%, as well as providing opportunity to implement the electronic health record, improving teamwork, and enhancing educational experiences for students. These benefits were achieved while maintaining high-quality patient care with zero adverse outcomes during and two years following the process improvement project.

    This paper represents an investigation into the determinants of young children's quality of life (QOL) in Thailand. The empirical work is based upon a sample of 498 children (aged 5-8); 220 were urban children and 278 children of construction workers in Bangkok. Their QOL was assessed using a new self-report QOL measure for children. Multiple regression analyses indicated that the father's income and education, type of school, mode of transportation to school, and the amount of time that the child spent on extra study courses were significant explanatory variables. It was found that these factors had different influences on the QOL of urban children and those of construction workers. Extra sport-related activities and extra work (other than housework) improved the QOL of urban children, while the QOL of construction workers' children was directly linked to father's education and income. This result is consistent with income having a diminishing marginal effect on the QOL of children. There is also evidence that amongst construction workers' children, boys have a lower QOL than girls. The different causal explanations for the QOL of urban and construction workers' children suggests that it is context specific, and what impacts one group of children's QOL within a particular context may not impact another group in a different situation. This has important policy implications. Throughout the study we could find no significant impact of health on QOL-neither chronic, acute nor severe illness has any significant impact on QOL. This is consistent with the hypothesis that QOL is influenced by expectations (Social Science and Medicine 41 (10) (1995) 1403). Findings of the effects of social and environmental factors on children's QOL are new in this field and should be further investigated.

    Ongoing efforts to decrease costs in the clinical laboratory make continuous process improvement especially important in difficult economic times. Process improvement can result in decreased workload, cost savings, and increased customer satisfaction but is an abstract concept in and of itself. To illustrate the steps of process improvement, we applied them to our blood component retrieval policy. By identifying the problems with the current system, proposing and implementing solutions, and measuring the effects before and after revamping the process, we have been able to show impressive reductions in the number of component retrievals initiated, the number acted on, wasted components, and customer complaints, all of which translate into cost savings. Once the cycle is completed, it begins anew. There must always be continuous process improvement.

    We aim to analyze factors associated with the quality of life (QOL) response of individuals with rheumatic diseases treated by the Public Health System (Sistema Único de Saúde) with biological disease-modifying antirheumatic drugs (bDMARDs). Data from 428 patients using bDMARDs were collected using a standardized form at baseline and 6 months after the onset of treatment. The average reduction of the scores on EuroQol-five dimension was 0.11 ± 0.18 6 months after the onset of treatment with bDMARDs, denoting significant improvement of the participants' QOL. All the investigated types of disease exhibited significant improvement at the 6-month assessment, without any difference among them (p = 0.965). The participants with baseline poorest functionality and best QOL exhibited the best QOL outcomes after 6 months of treatment. Our study showed that the use of biological drugs induced considerable improvement in the participants' QOL.

    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.

    Depressive symptoms and pain are common in patients on chronic hemodialysis (HD), yet their associations with quality of life (QOL) are not fully understood. We sought to characterize the longitudinal associations of these symptoms with QOL. As part of a trial comparing two symptom management strategies in patients receiving chronic HD, we assessed depressive symptoms using the Patient Health Questionnaire-9 (PHQ-9), and pain using the Short Form McGill Pain Questionnaire (SF-MPQ) monthly over 24 months. We assessed health-related QOL (HR-QOL) quarterly using the Short Form 12 (SF-12) and global QOL (G-QOL) using a single-item survey. We used random effects linear regression to analyze the independent associations of depressive symptoms and pain, scaled based on 5-point increments in symptom scores, with HR-QOL and G-QOL. Overall, 286 patients completed 1417 PHQ-9 and SF-MPQ symptom assessments, 1361 SF-12 assessments, and 1416 G-QOL assessments. Depressive symptoms were independently and inversely associated with SF-12 physical HR-QOL scores (β = -1.09; 95% confidence interval [CI]: -1.69, -0.50, P < 0.001); SF-12 mental HR-QOL scores (β = -4.52; 95% CI: -5.15, -3.89, P < 0.001); and G-QOL scores (β = -0.64; 95%CI: -0.79, -0.49, P < 0.001). Pain was independently and inversely associated with SF-12 physical HR-QOL scores (β = -0.99; 95% CI: -1.30, -0.68, P < 0.001) and G-QOL scores (β = -0.12; 95%CI: -0.20, -0.05, P = 0.002); but not with SF-12 mental HR-QOL scores (β = -0.16; 95%CI: -0.050, 0.17, P = 0.34). In patients receiving chronic HD, depressive symptoms and to a lesser extent pain, are independently associated with reduced HR-QOL and G-QOL. Interventions to alleviate these symptoms could potentially improve patients' HR-QOL and G-QOL.

    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.

    Bell layered space-time architecture (BLAST) is a multi-antenna communication structure with high spectrum efficiency, and it has found wide applications in LANs and WLANs. However, its performance is much poorer than those of other space-time coding approaches. In order to improve its performance, an improved BLAST based on RAKE receiving is investigated. The new system introduces orthogonal spreading sequences (OSS) into the transmitter while retains the basic structure of BLAST. The proposed receiver suppresses interferences from other antennas by the orthogonality contained in the received signals, and extracts information from each receiving antenna by using RAKE receiving principle to construct efficient statistic decision. Simulation results show that the improved system performs well over both frequency-flat and frequency-selective fading channels.

    NASA Dryden presents an improved and automated site-specific algorithm for heat-stress approximation using standard atmospheric measurements routinely obtained from the Edwards Air Force Base weather detachment. Heat stress, which is the net heat load a worker may be exposed to, is officially measured using a thermal-environment monitoring system to calculate the wet-bulb globe temperature (WBGT). This instrument uses three independent thermometers to measure wet-bulb, dry-bulb, and the black-globe temperatures. By using these improvements, a more realistic WBGT estimation value can now be produced. This is extremely useful for researchers and other employees who are working on outdoor projects that are distant from the areas that the Web system monitors. Most importantly, the improved WBGT estimations will make outdoor work sites safer by reducing the likelihood of heat stress.

    An improved ternary subdivision interpolation scheme was developed for computer graphics applications that can manipulate open control polygons unlike the previous ternary scheme, with the resulting curve proved to be still C2-continuous. Parameterizations of the limit curve near the two endpoints are given with expressions for the boundary derivatives. The split joint problem is handled with the interpolating ternary subdivision scheme. The improved scheme can be used for modeling interpolation curves in computer aided geometric design systems, and provides a method for joining two limit curves of interpolating ternary subdivisions.

    Peripartum cardiomyopathy (PPCM) is a rare condition with a diverse spectrum of potential outcomes, ranging from frequent complete recovery to fulminant heart failure and death. The pathogenesis of PPCM is not well understood, and relatively little is known about its incidence and prevalence. PPCM is often under-recognised in the clinical setting. Early investigation and diagnosis with subsequent expert management may improve outcomes. The development of registries will allow this condition to be better characterised and may help answer crucial questions regarding its optimal medical and surgical management. This paper reviews the potential approaches to improve outcomes in patients with PPCM.

    2014-08-01

    This article reviews the literature regarding the impact of cosmetic surgery on health-related quality of life (QOL). Studies were identified through PubMed/Medline and PsycINFO searches from January 1960 to December 2011. Twenty-eight studies were included in this review, according to specific selection criteria. The procedures and tools employed in cosmetic surgery research studies were remarkably diverse, thus yielding difficulties with data analysis. However, data indicate that individuals undergoing cosmetic surgery began with lower values on aspects of QOL than control subjects, and experienced significant QOL improvement post-procedurally, an effect that appeared to plateau with time. Despite the complexity of measuring QOL in cosmetic surgery patients, most studies showed an improvement in QOL after cosmetic surgery procedures. However, this finding was clouded by measurement precision as well as heterogeneity of procedures and study populations. Future research needs to focus on refining measurement techniques, including developing cosmetic surgery-specific QOL measures.

    2005-06-01

    In this paper, it is demonstrated that partnership arrangements between farmers might be a way to secure the economic viability of their farms as well as to increase profitability. The article discusses empirical analyses of three different forms of collaboration, with an emphasis on the environmental improvements associated with collaboration. Collaboration between a dairy farm and a crop farm is analyzed in the first case. The results show that potential gains from improved diversification and crop rotation are substantial, and even larger when the collaboration also involves machinery. The second analysis considers external integration between farrowing and finishing-pig operations. Gains from collaboration originate from biological and technical factors, such as improved growth rate of the pigs and better utilization of buildings. Finally, an evaluation of a group of collaborating crop farmers is performed. In this case, the benefits that arise are mainly due to reduced machinery costs and/or gains due to other factors, such as improved crop rotation and managerial/marketing strategies.

    The viscosity index of an oil or an oil formulation is an important physical parameter. Viscosity index improvers, VIIs, are comprised of five main classes of polymers: polymethylmethacrylates (PMAs), olefin copolymers (OCPs), hydrogenated poly(styrene-co-butadiene or isoprene) (HSD/SIP/HRIs), esterified polystyrene-co-maleic anhydride (SPEs) and a combination of PMA/OCP systems. The chemistry, manufacture, dispersancy and utility of each class are described. The comparative functions, properties, thickening ability, dispersancy and degradation of VIIs are discussed. Permanent and temporary shear thinning of VII-thickened formulations are described and compared. The end-use performance and choice of VI improvers is discussed in terms of low- and high-temperature viscosities, journal bearing oil film thickness, fuel economy, oil consumption, high-temperature pumping efficiency and deposit control. Discussion of future developments concludes that VI improvers will evolve to meet new challenges of increased thermal-oxidative degradation from increased engine operating temperatures, different base stocks of either synthetic base oils or vegetable oil-based, together with alcohol- or vegetable oil-based fuels. VI improvers must also evolve to deal with higher levels of fuel dilution and new types of sludge and also enhanced low-temperature requirements.

    Despite the potential of improved cookstoves to reduce the adverse environmental and health impacts of solid fuel use, their adoption and use remains low. Social marketing-with its focus on the marketing mix of promotion, product, price, and place-offers a useful way to understand household behaviors and design campaigns to change biomass fuel use. We report on a series of pilots across 3 Indian states that use different combinations of the marketing mix. We find sales varying from 0% to 60%. Behavior change promotion that combined door-to-door personalized demonstrations with information pamphlets was effective. When given a choice amongst products, households strongly preferred an electric stove over improved biomass-burning options. Among different stove attributes, reduced cooking time was considered most valuable by those adopting a new stove. Households clearly identified price as a significant barrier to adoption, while provision of discounts (e.g., rebates given if households used the stove) or payments in installments were related to higher purchase. Place-based factors such as remoteness and nongovernmental organization operations significantly affected the ability to supply and convince households to buy and use improved cookstoves. Collectively, these pilots point to the importance of continued and extensive testing of messages, pricing models, and different stove types before scale-up. Thus, we caution that a one-size-fits-all approach will not boost improved cookstove adoption.
