    Full Text Available Abstract Introduction Radiation recall dermatitis is a well known but still poorly understood inflammatory reaction. It can develop in previously irradiated areas and has been shown to be triggered by a variety of different drugs, including cytostatic agents. Pemetrexed may cause radiation recall dermatitis in pre-irradiated patients. Case presentation We present the case of a 49-year-old Caucasian woman with non-small cell lung cancer who was initially treated with carboplatin and paclitaxel concomitant with radiotherapy after suffering a painful plexus brachialis infiltration. Due to disease progression, a second-line treatment with pemetrexed was started. A severe soft tissue necrosis developed despite steroid treatment and plastic surgery. Conclusion To the best of our knowledge, we present the first case of a patient with severe soft tissue necrosis in a pre-irradiated area after pemetrexed therapy. We believe that physicians treating patients with pemetrexed should be aware of the severe, possibly life-threatening effects that may be induced by pemetrexed after previous radiation therapy.

    Standard platinum-based chemotherapy combinations for advanced non-small-cell lung cancer (NSCLC) have reached a plateau in terms of the survival benefit they offer for patients. In addition, the emerging clinical trend of tailored treatment based on patient characteristics has led to the development of therapeutic strategies that target specific cancer-related molecular pathways, including epidermal growth factor receptor (EGFR), angiogenesis, and anaplastic lymphoma kinase inhibitors. Current research is focused on combining targeted therapy with platinum-based chemotherapy in an endeavor to achieve an additional benefit in specific patient populations. Currently, pemetrexed is indicated for use in the first-line, maintenance, and second-line settings for the treatment of nonsquamous NSCLC. The combination of pemetrexed and cisplatin is well tolerated and is the approved standard first-line therapy. Thus, the pemetrexed-platinum backbone provides an attractive option for combination with targeted therapies. This review aims to summarize the current knowledge and future prospects of the use of pemetrexed-platinum as a backbone for combination with targeted therapies for NSCLC.

    Pemetrexed, a multitargeting antifolate cytotoxic drug, plays a leading role in front-line chemotherapy for patients with advanced non-squamous non-small-cell lung cancer (NSCLC). Following its approval as second-line monotherapy for locally advanced or metastatic non-squamous NSCLC, pemetrexed has established itself as the first-line regimen in combination with cisplatin, and its powerful antitumor effects and less cumulative toxicities were then taken advantage of in the JMEN and PARAMOUNT trials, respectively, to pioneer a new treatment strategy of switch and continuation maintenance monotherapy. These developments have brought about a marked paradigm shift, and made pemetrexed indispensable in the treatment for non-squamous NSCLC. So far, only three drugs have been approved for maintenance therapy; pemetrexed both by switch and continuation maintenance, erlotinib by switch maintenance, and bevacizumab by continuation maintenance. Compared with observation alone after defined cycles of the first-line chemotherapy, subsequent pemetrexed maintenance therapy has provided significantly longer survival and infrequent severe adverse events. The cost-effectiveness of pemetrexed maintenance therapy is controversial, as well as the other two maintenance drugs, bevacizumab and erlotinib. The latest attractive attention is a combination maintenance therapy. We may have to consider epidermal growth factor receptor (EGFR) mutation status for selection of a combination pattern. A combination maintenance therapy of pemetrexed plus bevacizumab is potential for patients with wild-type EGFR status, while a EGFR tyrosine kinase inhibitor-containing combination is promising for patients with active EGFR mutation status. Pemetrexed will be a pivotal drug when a combination maintenance therapy is used in practice. For future maintenance therapy, we need to explore reliable predictive selection or exclusion markers that can predict who will really benefit from maintenance therapy.

Pemetrexed, a new generation antifolate drug, is one of the primary treatments for breast cancer. However, multidrug resistance (MDR in breast cancer greatly hampers the therapeutic efficacy of chemotherapies such as pemetrexed. Nanomedicine is emerging as a promising alternative technique to overcome cancer MDR. Thus, pemetrexed-loaded d-alpha tocopheryl polyethylene glycol 1000 succinate (vitamin E TPGS liposomes (liposomal pemetrexed were developed as a strategy to overcome MDR to pemetrexed in breast cancer. Materials and methods: Liposomal pemetrexed was developed using the calcium acetate gradient method. The cytotoxic effects, apoptosis-inducing activity, in vivo distribution, and antitumor activity of liposomal pemetrexed were investigated. Results: Liposomal pemetrexed was small in size (160.77 nm, with a small polydispersity of <0.1. The encapsulation efficacy of liposomal pemetrexed was 63.5%, which is rather high for water-soluble drugs in liposomes.

    Pemetrexed, a thymidylate synthase (TS) and transferase inhibitor, is in phase III trials with Eli Lilly as a potential treatment for several common solid tumors, including non-small cell lung cancer (NSCLC) and mesothelioma [321789], [410731]. Studies on pemetrexed have concluded that not only is the compound a TS inhibitor but also a potent inhibitor of human dihydrofolate reductase (DHFR). The results suggest that pemetrexed acts upon multiple intracellular targets and that the antitumor effect may be derived from its simultaneous inhibition of multiple folate-requiring enzymes [203662]: this compound has been designated as a multitargeted antifolate (MTA) [386680]. The drug also causes concentration- and time-dependent apoptosis [284380]. Other studies in which the 4-oxo group of the pyrimidine ring portion of pemetrexed was replaced with a hydrogen atom, demonstrated that the resulting analogs were potent DHFR inhibitors with very little activity against the enzymes glycinamide ribonucleotide formyltransferase (GARFT) and TS [310674]. In phase II European studies in 64 patients with advanced breast cancer, encouraging responses were seen in anthracycline-failure (23%) and anthracycline-refractory (19%) patients. Responses were observed in 28% of patients who had been previously treated with a taxane [326097]. Data from a phase II trial of pemetrexed (500 mg/m2 once every 21 days as a 10 min i.v. infusion) as a salvage therapy in advanced breast cancer showed that supplementation of the treatment regime with folic acid (FA) and vitamin B12 reduced its already manageable and tolerable toxicities [408821], [409650]. At doses of 500 mg/m2, the drug was also safely administered to 35 patients with impaired renal function [409953]. Phase I and II trials have shown that the main side effects include neutropenia, thrombocytopenia, mucositis, nausea and vomiting [203666], [272241].

    Objectives: To evaluate abortion and fetal congenital anomaly rates in women previously submitted to radioiodine therapy for differentiated thyroid carcinoma. Study design: A case-control study of 108 pregnant women, 48 cases whose pregnancies were evaluated after they had undergone radioiodine therapy for differentiated thyroid carcinoma, and the control group consisted of 60 healthy pregnant women. Results: Of a total of 66 pregnancies, 14 conceived within the first year, 51 one or more years after the last administration of 131 I, the medical record of one patient was not available. The interval between the last radioiodine therapy administration and conception ranged from 1 month to 10 years. There were a total of 4 miscarriages, 2 of them for unknown reasons. There was one case of congenital anomaly and two preterms birth. Nine women presented the following pregnancy events: placental insufficiency, hypertensive crisis, placental detachment, risk of miscarriage, preterm labour and four miscarriages. No statistical difference was observed between the studied and control groups. Conclusion: Radioiodine was followed by no significant increase in untoward effects in neither the pregnancy nor the offspring. (author)

    Icotinib has been previously shown to be non-inferior to gefitinib in non-selected advanced non-small-cell lung cancer patients when given as second- or further-line treatment. In this open-label, randomized, phase 3 CONVINCE trial, we assessed the efficacy and safety of first-line icotinib versus cisplatin/pemetrexed plus pemetrexed maintenance in lung adenocarcinoma patients with epidermal growth factor receptor (EGFR) mutation. Eligible participants were adults with stage IIIB/IV lung adenocarcinoma and exon 19/21 EGFR mutations. Participants were randomly allocated (1 : 1) to receive oral icotinib or 3-week cycle of cisplatin plus pemetrexed for up to four cycles; non-progressive patients after four cycles were maintained with pemetrexed until disease progression or intolerable toxicity. The primary end point was progression-free survival (PFS) assessed by independent response evaluation committee. Other end points included overall survival (OS) and safety. Between January 2013 and August 2014, 296 patients were randomized, and 285 patients were treated (148 to icotinib, 137 to chemotherapy). Independent response evaluation committee-assessed PFS was significantly longer in the icotinib group (11.2 versus 7.9 months; hazard ratio, 0.61, 95% confidence interval 0.43-0.87; P = 0.006). No significant difference for OS was observed between treatments in the overall population or in EGFR-mutated subgroups (exon 19 Del/21 L858R). The most common grade 3 or 4 adverse events (AEs) in the icotinib group were rash (14.8%) and diarrhea (7.4%), compared with nausea (45.9%), vomiting (29.2%), and neutropenia (10.9%) in the chemotherapy group. AEs (79.1% versus 94.2%; P icotinib group than in the chemotherapy group. First-line icotinib significantly improves PFS of advanced lung adenocarcinoma patients with EGFR mutation with a tolerable and manageable safety profile. Icotinib should be considered as a first-line treatment for this patient population. © The Author

    Pemetrexed-platinum doublet therapy is a standard treatment for stage IIIb/IV nonsquamous non small cell lung cancer (NSCLC). While the regimen is associated with several grade ≥3 toxicities, hyponatremia is not a commonly reported adverse effect. Here we report an unusually high incidence of grade ≥3 hyponatremia in Indian patients receiving pemetrexed-platinum doublet, and the pharmacological basis for this phenomenon. Forty-six patients with advanced NSCLC were enrolled for a bioequivalence study of two pemetrexed formulations. All patients received the pemetrexed-platinum doublet for six cycles followed by single-agent pemetrexed maintenance until progression. Pharmacokinetic blood samples were collected at predefined time points during the first cycle and the concentration-time profile of pemetrexed was investigated by noncompartmental analysis. Hyponatremic episodes were investigated with serum electrolytes, serum osmolality, urinary sodium, and urine osmolality. Sixteen of 46 patients (35%) had at least one episode of grade ≥3 hyponatremia. Twenty-four episodes of grade ≥3 hyponatremia were observed in 200 cycles of doublet chemotherapy. Plasma exposure to pemetrexed was significantly higher in patients with high-grade hyponatremia than in those with low-grade or no hyponatremia (P=0.063 and P=0.001, respectively). Pemetrexed clearance in high-grade hyponatremia was quite low compared with normal and low-grade hyponatremia (P=0.001 and P=0.055, respectively). Median pemetrexed exposure in this cohort was much higher than that reported in the literature from Western studies. Higher exposure to pemetrexed is associated with grade ≥3 hyponatremia. The pharmacogenetic basis for higher exposure to pemetrexed in Indian patients needs further investigation

    Full Text Available Ranjit K GoudarDepartment of Medicine, Division of Hematology, Medical Oncology and Cellular Therapy, Duke University Medical Center, Durham, NC, USAAbstract: Malignant pleural mesothelioma is a resistant form of lung cancer, and its incidence continues to rise in Europe and Australia. Until recently, chemotherapy had not been shown to be effective in the treatment of this slowly progressive disease. In 2004, the combination of pemetrexed and cisplatin was shown to induce high response rates in MPM. This article reviews the published literature describing the development and testing of this therapeutic combination in mesothelioma, and examines in detail the key phase III clinical trial that led to the approval of pemetrexed by the US FDA. Ongoing research will further define the role of pemetrexed plus cisplatin in the treatment of MPM.Keywords: malignant pleural mesothelioma, mesothelioma, pemetrexed, cisplatin

    Continuation maintenance treatment with pemetrexed is approved by current clinical guidelines as a category 2A recommendation after induction therapy with cisplatin and pemetrexed chemotherapy (CP strategy) for patients with advanced nonsquamous non-small-cell lung cancer (NSCLC). However, the cost-effectiveness of the treatment remains unclear. We completed a trial-based assessment, from the perspective of the Chinese health care system, of the cost-effectiveness of maintenance pemetrexed treatment after a CP strategy for patients with advanced nonsquamous NSCLC. A Markov model was developed to estimate costs and benefits. It was based on a clinical trial that compared continuation maintenance pemetrexed therapy plus best supportive care (BSC) versus placebo plus BSC after a CP strategy for advanced nonsquamous NSCLC. Sensitivity analyses were conducted to assess the stability of the model. The model base case analysis suggested that continuation maintenance pemetrexed therapy after a CP strategy would increase benefits in a 1-, 2-, 5-, or 10-year time horizon, with incremental costs of $183,589.06, $126,353.16, $124,766.68, and $124,793.12 per quality-adjusted life-year gained, respectively. The most sensitive influential variable in the cost-effectiveness analysis was the utility of the progression-free survival state, followed by proportion of patients with postdiscontinuation therapy in both arms, proportion of BSC costs for PFS versus progressed survival state, and cost of pemetrexed. Probabilistic sensitivity analysis indicated that the cost-effective probability of adding continuation maintenance pemetrexed therapy to BSC was zero. One-way and probabilistic sensitivity analyses revealed that the Markov model was robust. Continuation maintenance of pemetrexed after a CP strategy for patients with advanced nonsquamous NSCLC is not cost-effective based on a recent clinical trial. Decreasing the price or adjusting the dosage of pemetrexed may be a better option

    Full Text Available Abstract Background Although first-line therapy for patients affected by advanced mesothelioma is well established, there is a lack of data regarding the impact of second-line treatment. Methods We retrospectively collected data of patients affected by advanced mesothelioma, already treated with first-line therapy based on pemetrexed and platin, with a response (partial response or stable disease lasting at least 6 months, and re-treated with a pemetrexed-based therapy at progression. The primary objective was to describe time to progression and overall survival after re-treatment. Results Overall across several Italian oncological Institutions we found 30 patients affected by advanced mesothelioma, in progression after a 6-month lasting clinical benefit following a first-line treatment with cisplatin and pemetrexed, and re-challenged with a pemetrexed-based therapy. In these patients we found a disease control rate of 66%, with reduction of pain in 43% of patients. Overall time to progression and survival were promising for a second-line setting of patients with advanced mesothelioma, being 5.1 and 13.6 months, respectively. Conclusions In our opinion, when a patient has a long-lasting benefit from previous treatment with pemetrexed combined with a platin compound, the same treatment should be offered at progression.

    Objectives: This article reviews pharmacology, pharmacokinetic properties, clinical efficacy, and safety in metastatic breast cancer patients, as well as the predictive biomarkers for outcome of treatment with pemetrexed-based regimens. Methods: PubMed, Embase, OVID, and the Cochrane Library databases were searched from the beginning of each database without any limitations to the date of publication. Search terms were‘‘pemetrexed’’ or‘‘LY231514’’ or“Alimta”,“metastatic breast cancer”, and“advanced breast cancer”. Results: There were 15 studies (n ¼ 1002) meeting our criteria for evaluation. Eight single-agent trials (n ¼ 551) and seven using combinations with other agents (n ¼ 451) were identified that evaluated pemetrexed for use in patients with metastatic breast cancer. Response rates to pemetrexed as a single agent varied from 8%to 31%, and with combination therapy have been reported to be between 15.8% and 55.7%. With routine supplementation of patients with folic acid, dexamethasone, and vitamin B12, the toxicity profile of these patients was mild, including dose-limiting neutropenia and thrombocytopenia, as well as lower grades of reversible hepatotoxicity and gastrointestinal toxicity. Expression of thymidylate synthase (TS) and other biomarkers are associated with the prognosis and sensitivity for pemetrexed in breast cancer. Conclusion: Pemetrexed has shown remarkable activity with acceptable toxicities for treatment of metastatic breast cancer patients. Translational research on pemetrexed in breast cancer identified biomarkers as well as additional genes important to its clinical activity and toxicity. Further research is needed to clarify the role of pemetrexed in breast cancer treatment in order to guide oncologists. Copyright © 2015, Chinese Medical Association Production.

    Gene therapy is one of the most attractive fields in medicine.

    Choroidal melanoma is the most common primary malignant intraocular tumor, and very few effective therapies are available to treat it. Our study aimed to understand whether pemetrexed plus cisplatin exerts a beneficial synergistic effect in human choroidal melanoma cells and to delineate the underlying molecular mechanism. To accomplish these aims, we treated choroidal melanoma cells with pemetrexed and cisplatin and assessed cell survival with SRB and MTT assays. Proteins were detected using western blotting analysis. NOXA and CHOP were knocked down with siRNA. We found that pemetrexed or cisplatin alone inhibited survival and induced apoptosis in human choroidal melanoma cells. Furthermore, the expression levels of c-FLIP, an anti-apoptotic protein in the extrinsic apoptosis pathway, and Mcl-1, an anti-apoptotic protein in the intrinsic apoptosis pathway, were decreased by pemetrexed or cisplatin respectively, while the expression of a pro-apoptotic protein in the intrinsic apoptosis pathway, NOXA, was up-regulated. Moreover, pemetrexed or cisplatin alone increased the protein expression of the endoplasmic reticulum stress markers IRE1α, Bip and CHOP. Silencing CHOP expression reduced NOXA expression. These findings suggest that the pemetrexed or cisplatin induced intrinsic apoptosis via activation of the ER stress response. Importantly, combining the two compounds more strongly induced apoptosis. Following the cotreatment, CHOP and NOXA expression increased, while c-FLIP and Mcl-1 expression decreased, and these effects were more pronounced than when using either compound alone. This result suggests that pemetrexed and cisplatin synergistically activate ER stress response-induced apoptosis in choroidal melanoma cells. To summarize, the c-FLIP and NOXA/Mcl-1 axis participated in the synergistic effect of pemetrexed plus cisplatin in human choroidal melanoma cells. Intrinsic apoptosis was induced via activation of the ER stress response. Our study provides

    Objectives: To evaluate abortion and fetal congenital anomaly rates in women previously submitted to radioiodine therapy for differentiated thyroid carcinoma. Study design: A case-control study of 108 pregnant women, 48 cases whose pregnancies were evaluated after they had undergone radioiodine therapy for differentiated thyroid carcinoma, and the control group consisted of 60 healthy pregnant women. Results: Of a total of 66 pregnancies, 14 conceived within the first year, 51 one or more years after the last administration of {sup 131}I, the medical record of one patient was not available. The interval between the last radioiodine therapy administration and conception ranged from 1 month to 10 years. There were a total of 4 miscarriages, 2 of them for unknown reasons. There was one case of congenital anomaly and two preterms birth. Nine women presented the following pregnancy events: placental insufficiency, hypertensive crisis, placental detachment, risk of miscarriage, preterm labour and four miscarriages. No statistical difference was observed between the studied and control groups. Conclusion: Radioiodine was followed by no significant increase in untoward effects in neither the pregnancy nor the offspring. (author)

    Sorafenib has demonstrated single agent activity in non-small cell (NSCLC) and small cell lung cancer (SCLC). Carboplatin/pemetrexed (CbP) and cisplatin/etoposide (PE) are commonly used in the treatment of these diseases. A phase I trial escalating doses of sorafenib in combination with fixed doses of PE (Arm A) or CbP (Arm B) was performed using a 3-patient cohort design to determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLT); DLT were assessed in the first cycle. The trial was subsequently amended with closure of Arm B and to include Arm C with a reduced dose of carboplatin. Between 9/2007 and 9/2008, 20 pts were treated on the trial; median age 62 (range 42-73), male/female ratio 12/8, PS 0/1 ratio 6/14, and median number of prior therapies 2 (range 1-4). The most common tumor types were NSCLC and SCLC. On Arm A at dose level 0 (sorafenib 200 mg BID), 2 of 4 patients experienced DLT; 2 patients were enrolled at dose level -1 (sorafenib 200 mg QD) without DLT, but this arm was closed due to slow accrual. On Arm B, 2 of 3 patients experienced DLT at dose level 0 (sorafenib 200 mg BID). On Arm C at dose level 0 (sorafenib 200 mg BID), 1 of 6 patients experienced DLT, and at dose level +1 (sorafenib 400 mg BID) 2 of 5 patients experienced a DLT. The MTD of sorafenib was 200 mg BID continuously in combination with carboplatin (AUC of 5) and pemetrexed 500 mg/m² every 3 weeks. However, only 6 patients were treated at this dose level, and the results should be interpreted cautiously. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    Pemetrexed is a new generation antifolate approved for the treatment of mesothelioma and non-small cell lung cancer. Caffeine is known to augment radiation or chemotherapeutic drug-induced cell killing. The current study addresses the impact of caffeine on the activity of pemetrexed in mesothelioma cell lines. Caffeine enhanced pemetrexed activity in all four mesothelioma cell lines tested (H2052, H2373, H28 and MSTO-211H). Caffeine sensitized H2052 cells in a dose- and schedule-dependent manner, and was associated with a markedly decreased clonogenic survival. Caffeine sensitization occurred only in cells subjected to pulse, but not continuous, exposure to pemetrexed. Similar pemetrexed sensitization was also observed with the clinically better tolerated caffeine analog, theobromine. Pemetrexed sensitization by caffeine was associated with an increase in pemetrexed-induced phosphorylation of ataxia-telangiectasia-mutated (ATM) and Chk1. These data indicate that caffeine and its analog, theobromine, may be a useful approach to enhance pemetrexed-based chemotherapy. PMID:17594092

    In recent years, the treatment landscape in advanced non-squamous non-small-cell lung cancer (nsNSCLC) has changed. New therapies (e.g., bevacizumab indicated in first line) have become available and other therapies (e.g., pemetrexed in first line and second line) moved into earlier lines in the treatment paradigm. While there has been an expansion of the available treatment options, it is still a key research question which therapy sequence results in the best survival outcomes for patients with nsNSCLC. A therapy-sequencing disease model that approximates treatment outcomes in up to five lines of treatment was developed for patients with nsNSCLC. The primary source of data for progression-free survival (PFS) and time to death was published pivotal trial data. All patients were treatment-naïve and in the PFS state, received first-line treatment with either bevacizumab-based therapy or doublet chemotherapy (including the option of pemetrexed + cisplatin). Patients would then progress to a subsequent line of therapy, remain in PFS or die. In case of progression, it was assumed that each survivor would receive a subsequent line of therapy, based on EMA licensed therapies. Weibull distribution curves were fitted to the data. All bevacizumab-based first-line therapy sequences analyzed achieved total PFS of around 15 months. Bevacizumab + carboplatin + paclitaxel (first line) → pemetrexed (second line) → erlotinib (third line) → docetaxel (fourth line) resulted in total mean PFS time of 15.7 months, for instance. Sequences with pemetrexed in combination with cisplatin in first line achieved total PFS times between 12.6 and 12.8 months with a slightly higher total PFS time achieved when assuming pemetrexed continuation therapy in maintenance after pemetrexed + cisplatin in first-line induction. Overall survival results followed the same trend as PFS. The model suggests that treatment-sequencing strategies starting with a bevacizumab-based combination in first line

    Pemetrexed is a multitargeted, antifolate, antineoplastic agent that is indicated for single-agent use in locally advanced or metastatic non-small-cell lung cancer after prior chemotherapy and in combination with cisplatin for the treatment of malignant pleural mesothelioma not treatable by surgery. Currently, there is no information on the long-term stability of pemetrexed beyond 24 hours. To evaluate the longer-term physical and chemical stability of pemetrexed 2, 10, and 20 mg/mL in polyvinyl chloride (PVC) bags of dextrose 5% injection and NaCl 0.9% injection. Triplicate samples of pemetrexed were prepared in the concentrations and infusion solutions required. Evaluations for physical and chemical stability were performed initially and over 2 days at 23 degrees C protected from light and exposed to fluorescent light, and over 31 days of storage at 4 degrees C protected from light. Physical stability was assessed using turbidimetric and particulate measurement as well as visual observation. Chemical stability was evaluated by HPLC. All pemetrexed solutions remained chemically stable, with little or no loss of pemetrexed over 2 days at 23 degrees C, protected from light and exposed to fluorescent light, and over 31 days of storage at 4 degrees C, protected from light. The room temperature samples were physically stable throughout the 48 hour test period. However, pemetrexed admixtures developed large numbers of microparticulates during refrigerated storage exceeding 24 hours. Pemetrexed is chemically stable for 2 days at room temperature and 31 days refrigerated in dextrose 5% injection and NaCl 0.9% injection. However, substantial numbers of microparticulates may form in pemetrexed diluted in the infusion solutions in PVC bags, especially during longer periods of refrigerated storage. Limiting the refrigerated storage period to the manufacturer-recommended 24 hours will limit particulate formation.

    In non-small cell lung cancer (NSCLC), the well-developed epidermal growth factor receptor (EGFR) is an important therapeutic target. EGFR activating gene mutations have been proved strongly predictive of response to EGFR-tyrosine kinase inhibitors (TKI) in NSCLC. However, both in daily clinical practice and clinical trials, patients with unknown EGFR gene status (UN-EGFR-GS) are very common. In this study, we assessed efficacy and tolerability of sequential treatment of first-line pemetrexed followed by icotinib in Chinese advanced lung adenocarcinoma with UN-EGFR-GS. We analyzed 38 patients with advanced lung adenocarcinoma with UN-EGFR-GS treated with first-line pemetrexed-based chemotherapy followed by icotinib as maintenance or second-line therapy. The response rates to pemetrexed and icotinib were 21.1% and 42.1%, respectively. The median overall survival was 27.0 months (95% CI, 19.7-34.2 months). The 12-month overall survival probability was 68.4%. The most common toxicities observed in icotinib phase were rashes, diarrheas, and elevated aminotransferase. Subgroup analysis indicated that the overall survival is correlated with response to icotinib. The sequence of first-line pemetrexed-based chemotherapy followed by icotinib treatment is a promising option for advanced lung adenocarcinoma with UN-EGFR-GS in China.

    Full Text Available The preparation of stable amorphous pemetrexed disodium of pharmaceutical purity as well as the process optimization for the preparation of the hemipentahydrate form of pemetrexed disodium are described. Analytical methods for the polymorphic and chemical purity studies of pemetrexed disodium and pemetrexed diacid forms were developed. The physicochemical properties of the amorphous and hydrate forms of pemetrexed disodium, as well as new forms of pemetrexed diacid (a key synthetic intermediate were studied by thermal analysis and powder X-ray diffraction. High-performance liquid chromatography and gas chromatography methods were used for the chemical purity and residual solvents determination. In order to study the polymorphic and chemical stability of the amorphous and hemipentahydrate forms, a hygroscopicity test (25 °C, 80% RH was performed. Powder diffraction and high-performance liquid chromatography analyses revealed that the amorphous character and high chemical purity were preserved after the hygroscopicity test. The hemipentahydrate form transformed completely to the heptahydrate form of pemetrexed disodium. Both pemetrexed disodium forms were produced with high efficiency and pharmaceutical purity in a small commercial scale. Amorphous pemetrexed disodium was selected for further pharmaceutical development. Two new polymorphs (forms 1 and 2 of pemetrexed diacid were used for the preparation of high purity amorphous pemetrexed disodium.

    Full Text Available Abstract Background To improve the efficacy of first-line therapy for advanced non-small cell lung cancer (NSCLC, additional maintenance chemotherapy may be given after initial induction chemotherapy in patients who did not progress during the initial treatment, rather than waiting for disease progression to administer second-line treatment. Maintenance therapy may consist of an agent that either was or was not present in the induction regimen. The antifolate pemetrexed is efficacious in combination with cisplatin for first-line treatment of advanced NSCLC and has shown efficacy as a maintenance agent in studies in which it was not included in the induction regimen. We designed a phase III study to determine if pemetrexed maintenance therapy improves progression-free survival (PFS and overall survival (OS after cisplatin/pemetrexed induction therapy in patients with advanced nonsquamous NSCLC. Furthermore, since evidence suggests expression levels of thymidylate synthase, the primary target of pemetrexed, may be associated with responsiveness to pemetrexed, translational research will address whether thymidylate synthase expression correlates with efficacy outcomes of pemetrexed. Methods/Design Approximately 900 patients will receive four cycles of induction chemotherapy consisting of pemetrexed (500 mg/m2 and cisplatin (75 mg/m2 on day 1 of a 21-day cycle. Patients with an Eastern Cooperative Oncology Group performance status of 0 or 1 who have not progressed during induction therapy will randomly receive (in a 2:1 ratio one of two double-blind maintenance regimens: pemetrexed (500 mg/m2 on day 1 of a 21-day cycle plus best supportive care (BSC or placebo plus BSC. The primary objective is to compare PFS between treatment arms. Secondary objectives include a fully powered analysis of OS, objective tumor response rate, patient-reported outcomes, resource utilization, and toxicity.

    Tyrosine kinase inhibitors of the epidermal growth factor receptor (EGFR) are becoming the standard treatment option for patients with advanced non-small cell lung cancer (NSCLC) harboring an EGFR mutation, but the economic impact of this practice is unclear, especially in a health resource-limited setting. A decision-analytic model was developed to simulate 21-day patient transitions in a 10-year time horizon. The health and economic outcomes of four first-line strategies (pemetrexed plus cisplatin [PC] alone, PC followed by maintenance with pemetrexed, or initial treatment with gefitinib or icotinib) among patients harboring EGFR mutations were estimated and assessed via indirect comparisons. Costs in the Chinese setting were estimated. The primary outcome was the incremental cost-effectiveness ratio (ICER). Sensitivity analyses were performed. The icotinib strategy resulted in greater health benefits than the other three strategies in NSCLC patients harboring EGFR mutations. Relative to PC alone, PC followed by pemetrexed maintenance, gefitinib and icotinib resulted in ICERs of $104,657, $28,485 and $19,809 per quality-adjusted life-year gained, respectively. The cost of pemetrexed, the EGFR mutation prevalence and the utility of progression-free survival were factors that had a considerable impact on the model outcomes. When the icotinib Patient Assistance Program was available, the economic outcome of icotinib was more favorable. These results indicate that gene-guided therapy with icotinib might be a more cost-effective treatment option than traditional chemotherapy.

    A comparative study of two radiation-hygienic methods of interstitial gamma-therapy: with subsequent introduction of radioactive needles of a standard type; with subsequent manual introduction of 60 Co sources have been carried out. Chronometry-dosimetric methods of investigation and the methods of individual dosimetry underlie the studies. The obtained data showed, that doses of irradiation to which medical personnel is subjected during the use of the method of subsequent manual introduction of the active sources are 3-4 times lower, than those during the introduction of standard radioactive needles with a higher quality of the procedure performance, ensuring a good therapeutic effect. All this makes it possible to consider interstitial gamma-therapy with the use of the principle of subsequent introduction of the source to be a more perspective method than interstitial gamma-therapy with the use standard radioactive needless 60 Co

    Purpose: To evaluate the feasibility and safety of concurrent pemetrexed/cisplatin/thoracic radiotherapy followed by consolidation pemetrexed/cisplatin for unresectable Stage IIIA/B non-small-cell lung cancer (NSCLC). Methods and Materials: Eligible patients with 2 on Days 1 and 22 for Dose Levels 1, 2, and 3/4, respectively) and cisplatin (25 mg/m 2 Days 1-3 for Dose Levels 1-3; 20 mg/m 2 Days 1-5 for Dose Level 4) concurrent with thoracic radiation (61-66 Gy in 31-35 fractions). Consolidation consisted of two cycles of pemetrexed/cisplatin (500 mg/m 2 , 75 mg/m 2 ) 21 days apart, after concurrent therapy. Results: Between January 2006 and October 2007, 16 patients entered the study. Median follow-up was 17.2 months. No dose-limiting toxicities were observed. Median radiation dose was 64 Gy (range, 45-66 Gy). Rates of significant Grade 3/4 hematologic toxicity were 38% and 7%, respectively. One patient experienced Grade 3 acute esophagitis, and 2 experienced late (Grade 3) esophageal stricture, successfully managed with dilation. One patient experienced Grade 3 pneumonitis. The overall response rate was 88%. One-year overall survival was 81%. Conclusions: Full systemic dose pemetrexed seems to be safe with full-dose cisplatin and thoracic radiation in Stage IIIA/B NSCLC. Pemetrexed is the first third-generation cytotoxic agent tolerable at full dose in this setting. A Phase II study evaluating Dose Level 4 is ongoing.

    This phase I study aims at assessing the safety and tolerability of LY2603618, a selective inhibitor of Checkpoint Kinase 1, in combination with pemetrexed and determining the maximum tolerable dose and the pharmacokinetic parameters. This was an open-label, multicenter, dose-escalation study in patients with advanced solid tumors. Increasing doses of LY2603618 (40-195 mg/m(2)) were combined with 500 mg/m(2) of pemetrexed. LY2603618 was administered on Days 1 and 9 and pemetrexed on Day 8 in a 28-day cycle. For all subsequent 21-day cycles, pemetrexed was administered on Day 1 and LY2603618 on Day 2. Antitumor activity was evaluated as per Response Evaluation Criteria in Solid Tumors 1.0. A total of 31 patients were enrolled into six cohorts (three at 40 mg/m(2) over 4.5-hour infusion, 1-hour infusion in subsequent cohorts: three each at 40 mg/m(2), 70 mg/m(2), and 195 mg/m(2); 13 at 105 mg/m(2); six at 150 mg/m(2)). Four patients experienced a dose-limiting toxicity: diarrhea (105 mg/m(2)); reversible infusion-related reaction (150 mg/m(2)); thrombocytopenia (195 mg/m(2)); and fatigue (195 mg/m(2)). The maximum tolerated dose was defined as 150 mg/m(2). The pharmacokinetic data demonstrated that the exposure of LY2603618 increased in a dose-dependent manner, displayed a suitable half-life for maintaining required human exposures while minimizing the intra- and inter-cycle accumulation, and was unaffected by the pemetrexed administration. The pharmacokinetic-defined biologically efficacious dose was achieved at doses ≥105 mg/m(2). LY2603618 administered approximately 24 h after pemetrexed showed acceptable safety and pharmacokinetic profiles.

    Full Text Available This report presents the case of a 60-year-old woman who was diagnosed with stage IV lung adenocarcinoma with asymptomatic brain metastases and commenced chemotherapy with cisplatin/pemetrexed (CDDP/Pem. She experienced tonic-clonic convulsions on day 9 of the first cycle, which were accompanied by increased blood pressure (173/69 mm Hg and headache. Therefore, brain MRI was performed to check for stroke or progression of brain metastatic foci. T2-weighted, FLAIR, and ADC map images showed high-intensity areas in the subcortical region of the bilateral parieto-occipital lobes, leading to a diagnosis of posterior reversible encephalopathy syndrome (PRES. The symptoms improved after treatment with antihypertensive and antiepileptic drugs. Clinicians should keep it in mind that central nervous system symptoms during anticancer therapy containing Pem may indicate possible PRES.

    Full Text Available Maintenance pemetrexed offers survival benefit with well-tolerated toxicities for advanced non-squamous non-small cell lung cancer (NSCLC. We present 3 consecutively enrolled patients with advanced non-squamous NSCLC, receiving stereotactic ablative radiotherapy (SABR for oligoprogressive disease during maintenance pemetrexed. All of them had sustained local control of thoracic oligoprogression after the SABR, while maintenance pemetrexed were kept for additionally long progression-free interval. SABR targeting oligoprogression with continued pemetrexed is an effective and safe approach to extend exposure of maintenance pemetrexed, thus maximizing the benefit from it.

    Data from murine models suggest that CD40 activation may synergize with cytotoxic chemotherapy. We aimed to determine the maximum tolerated dose (MTD) and toxicity profile and to explore immunological biomarkers of the CD40-activating antibody CP-870,893 with cisplatin and pemetrexed in patients with malignant pleural mesothelioma (MPM). Eligible patients had confirmed MPM, ECOG performance status 0-1, and measurable disease. Patients received cisplatin 75 mg/m(2) and pemetrexed 500 mg/m(2) on day 1 and CP-870,893 on day 8 of a 21-day cycle for maximum 6 cycles with up to 6 subsequent cycles single-agent CP-870,893. Immune cell subset changes were examined weekly by flow cytometry. Fifteen patients were treated at three dose levels. The MTD of CP-870,893 was 0.15 mg/kg, and was exceeded at 0.2 mg/kg with one grade 4 splenic infarction and one grade 3 confusion and hyponatraemia. Cytokine release syndrome (CRS) occurred in most patients (80%) following CP-870,893. Haematological toxicities were consistent with cisplatin and pemetrexed chemotherapy. Six partial responses (40%) and 9 stable disease (53%) as best response were observed. The median overall survival was 16.5 months; the median progression-free survival was 6.3 months. Three patients survived beyond 30 months. CD19+ B cells decreased over 6 cycles of chemoimmunotherapy (P CP-870,893 with cisplatin and pemetrexed is safe and tolerable at 0.15 mg/kg, although most patients experience CRS. While objective response rates are similar to chemotherapy alone, three patients achieved long-term survival. ACTRN12609000294257. © The Author 2015.

    Combination therapy using anticancer drugs and nucleic acid is a more promising strategy to overcome multidrug resistance in cancer and to enhance apoptosis. In this study, lipid-polymer hybrid nanoparticles (LPNs), which contain both pemetrexed and miR-21 antisense oligonucleotide (anti-miR-21), have been developed for treatment of glioblastoma, the most aggressive type of brain tumor. Prepared LPNs have been well characterized by particle size distribution and zeta potential measurements, determination of encapsulation efficiency, and in vitro release experiments. Morphology of LPNs was determined by transmission electron microscopy. LPNs had a hydrodynamic size below 100 nm and exhibited sustained release of pemetrexed up to 10 h. Encapsulation of pemetrexed in LPNs increased cellular uptake from 6% to 78%. Results of confocal microscopy analysis have shown that co-delivery of anti-miR-21 significantly improved accumulation of LPNs in the nucleus of U87MG cells. Nevertheless, more effective cytotoxicity results could not be obtained due to low concentration of anti-miR-21, loaded in LPNs. We expect that the effective drug delivery systems can be obtained with higher concentration of anti-miR-21 for the treatment of glioblastoma.

The treatment of RSM remains challenging, and the role of intravenous immunoglobulin (IVIG in RSM is controversial. Case report: Mrs HM, 37 years old, obstetric summary: P0+1+13+1, a known case of hypothyroidism/polycystic ovary syndrome, married to an unrelated 47-year-old man, presented to our RSM clinic in early January 2014 for investigation and treatment. She has had multiple failed in vitro fertilization trials and 13 first-trimester missed miscarriages terminating at 6–7 weeks, all without IVIG therapy. Her tenth pregnancy was spontaneous, managed in London, UK, with multiple supportive therapy and courses of IVIG starting from the third to the 30th week of pregnancy. The pregnancy ended at 36 weeks of gestation with a cesarean section and a live girl baby was delivered. Mrs HM had balanced translocation, 46XX t (7:11 (p10:q10. Preimplantation genetic diagnosis/intracytoplasmic sperm injection/in vitro fertilization was performed with embryo transfer on May 29, 2014, and resulted in a successful pregnancy. She was commenced immediately on metformin, luteal support, and IVIG therapy, started at 6 weeks of gestation and at monthly intervals until 30 weeks of gestation, and also received additional therapy. The pregnancy was monitored with ultrasound, progressed uneventfully until admission at 35 weeks of gestation, with mildly elevated liver enzymes and suspected fetal growth restriction.

    Home-based care in oncology is mainly reserved for patients at the end of life. Regulations regarding home delivery of cytotoxics differ across Europe, with a notable lack of practice guidelines in most countries. This has led to a lack of data addressing the feasibility of home-based administration of cytotoxic chemotherapy. In advanced non-squamous non-small cell lung cancer, pemetrexed is approved as maintenance therapy after first-line chemotherapy. In this setting, patients have the potential to be treated long-term with maintenance therapy, which, in the absence of unacceptable toxicity, is continued until disease progression. The favourable safety profile of pemetrexed and the ease of its administration by 10-minute intravenous infusion every 3 weeks make this drug a suitable candidate for administration in a home setting. Literature and regulations relevant to the home-based delivery of cytotoxic therapy were reviewed, and a phase II feasibility study of home administration of pemetrexed maintenance therapy was designed. At least 50 patients with advanced non-squamous non-small cell lung cancer, Eastern Cooperative Oncology Group performance status 0-1 and no progressive disease after four cycles of platinum-based first-line therapy are required to allow investigation of the feasibility of home-based administration of pemetrexed maintenance therapy (500 mg/m(2) every 3 weeks until progressive disease or unacceptable toxicity). Feasibility is being assessed as adherence to the home-based administration process (primary endpoint), patient safety, impact on patients' quality of life, patient and physician satisfaction with home care, and healthcare resource use and costs. Enrolment of patients from the UK and Sweden, where home-based care is relatively well developed, commenced in December 2011. This feasibility study addresses an important aspect of maintenance therapy, that is, patient comfort during protracted home-based chemotherapy. The study design

    Combination of chemotherapy and epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) had been proved to be a potent anti-drug for the treatment of tumors. However, survival time was not extended for the patients with lung adenocarcinoma (AdC) compared with first-line chemotherapy. In the present study, we attempt to assess the optimal schedule of the combined administration of pemetrexed and icotinib/erlotinib in AdC cell lines. Human lung AdC cell lines with wild-type (A549), EGFR T790M (H1975) and activating EGFR mutation (HCC827) were applied in vitro to assess the differential efficacy of various sequential regimens on cell viability, cell apoptosis and cell cycle distribution. The results suggested that the antiproliferative effect of the sequence of pemetrexed followed by icotinib/erlotinib was more effective than that of icotinib/erlotinib followed by pemetrexed. Additionally, a reduction of G1 phase and increased S phase in sequence of pemetrexed followed by icotinib/erlotinib was also observed, promoting cell apoptosis. Thus, the sequential administration of pemetrexed followed by icotinib/erlotinib exerted a synergistic effect on HCC827 and H1975 cell lines compared with the reverse sequence. The sequential treatment of pemetrexed followed by icotinib/erlotinib has been demonstrated promising results. This treatment strategy warrants further confirmation in patients with advanced lung AdC.

    Previous studies have shown that both pemetrexed, a cytotoxic drug, and erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), inhibit the cell growth of pancreatic cancer cells. However, whether they exert a synergistic antitumor effect on pancreatic cancer cells remains unknown. The present study aimed to assess the synergistic effect of erlotinib in combination with pemetrexed using different sequential administration schedules on the proliferation of human pancreatic cancer BXPC-3 and PANC-1 cells and to probe its cellular mechanism. The EGFR and K-ras gene mutation status was examined by quantitative PCR high-resolution melting (qPCR-HRM) analysis. BXPC-3 and PANC-1 cells were incubated with pemetrexed and erlotinib using different administration schedules. MTT assay was used to determine cytotoxicity, and cell cycle distribution was determined by flow cytometry. The expression and phosphorylation of EGFR, HER3, AKT and MET were determined using Western blotting. Both pemetrexed and erlotinib inhibited the proliferation of BXPC-3 and PANC-1 cells in a dose- and time-dependent manner in vitro. Synergistic effects on cell proliferation were observed when pemetrexed was used in combination with erlotinib. The degree of the synergistic effects depended on the administration sequence, which was most obvious when erlotinib was sequentially administered at 24-h interval following pemetrexed. Cell cycle studies revealed that pemetrexed induced S arrest and erlotinib induced G(0)/G(1) arrest. The sequential administration of erlotinib following pemetrexed induced S arrest. Western blot analyses showed that pemetrexed increased and erlotinib decreased the phosphorylation of EGFR, HER3 and AKT, respectively. However, both pemetrexed and erlotinib exerted no significant effects on the phosphorylation of c-MET. The phosphorylation of EGFR, HER3 and AKT was significantly suppressed by scheduled incubation with pemetrexed followed by erlotinib

    Full Text Available Thyroid storm is a rare and potentially life-threatening medical emergency. We experienced a case of thyroid storm associated with sepsis caused by pneumonia, which had a catastrophic course including recurrent cardiac arrest and subsequent multiple organ failure (MOF. A 22-year-old female patient with a 10-year history of Graves’ disease was transferred to our emergency department (ED. She had a cardiac arrest at her home and a second cardiac arrest at the ED. Her heart recovered after 20 min of cardiac resuscitation. She was diagnosed with thyroid storm associated with hyperthyroidism complicated by pneumonia and sepsis. Although full conventional medical treatment was given, she had progressive MOF and hemodynamic instability consisting of hyperthermia, tachycardia and hypotension. Because of hepatic and renal failure with refractory hypotension, we reduced the patient’s dose of beta-blocker and antithyroid drug, and she was started on continuous veno-venous renal replacement therapy (CRRT with intravenous albumin and plasma supplementation. Subsequently, her body temperature and pulse rate began to stabilize within 1 h, and her blood pressure reached 120/60 mmHg after 6 h. We discontinued antithyroid drug 3 days after admission because of aggravated hyperbilirubinemia. The patient exhibited progressive improvement in thyroid function even after cessation of antithyroid drug, and she successfully recovered from thyroid storm and MOF. This is the first case of thyroid storm successfully treated by CRRT in a patient considered unfit for antithyroid drug treatment.

    Purpose: To investigate the roles of radiation therapy and chemotherapy in the occurrence of subsequent leukemia after childhood cancer. Methods and Materials: We analyzed data from a case-control study with 35 cases and 140 controls. The active bone marrow (ABM) was segmented into 19 compartments, and the radiation dose was estimated in each. The chemotherapy drug doses were also estimated to enable adjustments. Models capable of accounting for radiation dose heterogeneity were implemented for analysis. Results: Univariate analysis showed a significant trend in the increase of secondary leukemia risk with radiation dose, after accounting for dose heterogeneity (P=.046). This trend became nonsignificant after adjustment for doses of epipodophyllotoxins, alkylating agents, and platinum compounds and the first cancer on multivariate analysis (P=.388). The role of the radiation dose appeared to be dwarfed, mostly by the alkylating agents (odds ratio 6.9, 95% confidence interval 1.9-25.0). Among the patients who have received >16 Gy to the ABM, the radiogenic risk of secondary leukemia was about 4 times greater in the subgroup with no alkylating agents than in the subgroup receiving ≥10 g/m{sup 2}. Conclusions: Notwithstanding the limitations resulting from the size of our study population and the quite systematic co-treatment with chemotherapy, the use of detailed information on the radiation dose distribution to ABM enabled consideration of the role of radiation therapy in secondary leukemia induction after childhood cancer.

    Background: We consider the use of dermal matrix associated with a skin graft to cover deep wounds in the extremities when tendon and bone are exposed. The objective of this article was to evaluate the efficacy of covering acute deep wounds through the use of a dermal regeneration template (Integra) associated with vacuum therapy and subsequent skin grafting. Methods: Twenty patients were evaluated prospectively. All of them had acute (up to 3 weeks) deep wounds in the limbs. We consider a deep wound to be that with exposure of bone, tendon, or joint. Results: The average area of integration of the dermal regeneration template was 86.5%. There was complete integration of the skin graft over the dermal matrix in 14 patients (70%), partial integration in 5 patients (25%), and total loss in 1 case (5%). The wound has completely closed in 95% of patients. Conclusions: The use of Integra dermal template associated with negative-pressure therapy and skin grafting showed an adequate rate of resolution of deep wounds with low morbidity. PMID:25289363

    Pemetrexed, a multitargeted antifolate, is eliminated by tubular secretion via human organic anion transporter 3 (hOAT3). Although proton pump inhibitors (PPIs) are frequently used in cancer patients, the drug interaction between PPIs and pemetrexed remains to be clarified. In this study, we examined the drug interaction between pemetrexed and PPIs in hOAT3-expressing cultured cells, and retrospectively analyzed the impact of PPIs on the development of hematologic toxicity in 108 patients who received pemetrexed and carboplatin treatment of nonsquamous non-small cell lung cancer for the first time between January 2011 and June 2015. We established that pemetrexed was transported via hOAT3 (Km = 68.3 ± 11.1 µM). Lansoprazole, rabeprazole, pantoprazole, esomeprazole, omeprazole, and vonoprazan inhibited hOAT3-mediated uptake of pemetrexed in a concentration-dependent manner. The inhibitory effect of lansoprazole was much greater than those of other PPIs and the apparent IC50 value of lansoprazole against pemetrexed transport via hOAT3 was 0.57 ± 0.17 µM. The inhibitory type of lansoprazole was competitive. In a retrospective study, multivariate analysis revealed that coadministration of lansoprazole, but not other PPIs, with pemetrexed and carboplatin was an independent risk factor significantly contributing to the development of hematologic toxicity (odds ratio: 10.004, P = 0.005). These findings demonstrated that coadministration of lansoprazole could exacerbate the hematologic toxicity associated with pemetrexed, at least in part, by competitive inhibition of hOAT3. Our results would aid clinicians to make decisions of coadministration drugs to avoid drug interaction-induced side effects for achievement of safe and appropriate chemotherapy with pemetrexed.

    Pemetrexed (PEM) improves the overall survival of patients with advanced non-small cell lung cancer (NSCLC) when administered as maintenance therapy. However, PEM resistance often appears during the therapy. Although thymidylate synthase is known to be responsible for PEM resistance, no other mechanisms have been investigated in detail. In this study, we explored new drug resistance mechanisms of PEM-treated NSCLC using two combinations of parental and PEM-resistant NSCLC cell lines from PC-9 and A549. PEM increased the apoptosis cells in parental PC-9 and the senescent cells in parental A549. However, such changes were not observed in the respective PEM-resistant cell lines. Quantitative RT-PCR analysis revealed that, besides an increased gene expression of thymidylate synthase in PEM-resistant PC-9 cells, the solute carrier family 19 member1 ( SLC19A1) gene expression was markedly decreased in PEM-resistant A549 cells. The siRNA-mediated knockdown of SLC19A1 endowed the parental cell lines with PEM resistance. Conversely, PEM-resistant PC-9 cells carrying an epidermal growth factor receptor (EGFR) mutation acquired resistance to a tyrosine kinase inhibitor erlotinib. Although erlotinib can inhibit the phosphorylation of EGFR and Erk, it is unable to suppress the phosphorylation of Akt in PEM-resistant PC-9 cells. Additionally, PEM-resistant PC-9 cells were less sensitive to the PI3K inhibitor LY294002 than parental PC-9 cells. These results indicate that SLC19A1 negatively regulates PEM resistance in NSCLC, and that EGFR-tyrosine-kinase-inhibitor resistance was acquired with PEM resistance through Akt activation in NSCLC harboring EGFR mutations.

    Full Text Available Cytoreductive surgery (CRS with heated intraoperative intraperitoneal chemotherapy (HIPEC has emerged as optimal treatment for diffuse malignant peritoneal mesothelioma (DMPM showing median survivals of 36–92 months. However, recurrences occur frequently even in patients undergoing optimal cytreduction and are often confined to the abdomen. We initiated a Phase II study of adjuvant intraperitoneal pemetrexed combined with intravenous cisplatin for patients undergoing CRS and HIPEC for DMPM. The treatment consisted of pemetrexed 500 mg/m2 intraperitoneally and cisplatin 50 mg/m2 intravenously given simultaneously on day 1 of every 21 day cycle for 6 cycles. The primary endpoint of the study was treatment related toxicity. From July 2007 until July 2009 ten patients were enrolled. Nine of 10 completed all 6 cycles of adjuvant treatment per protocol. The most common toxicities were fatigue, nausea and abdominal pain grade 1 or 2. There was one grade 3 toxicity consisting of a catheter infection. The median survival for all 10 patients was 33.5 months. Pharmacokinetic analysis of intraperitoneal pemetrexed showed a peritoneal to plasma area under the curve ratio of 70. Our study shows that adjuvant intravenous cisplatin and intraperitoneal pemetrexed can be used following CRS and HIPEC for DMPM with low morbidity.

    Most patients with lung cancer have non-small cell lung cancer (NSCLC) subtype and have advanced disease at the time of diagnosis. Improvements in both first-line and subsequent therapies are allowing longer survival and enhanced quality of life for these patients. The median overall survival observed in many second-line trials is approximately 9 months, and many patients receive further therapy after second-line therapy. The cytotoxic agents pemetrexed and docetaxel and the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) erlotinib and gefitinib are standard second-line therapies. For patients with EGFR mutation, a TKI is the favored second-line therapy if not already used in first-line therapy. For patients without the EGFR mutation, TKIs are an option, but many oncologists favor cytotoxic therapy. The inhibitor of the EML4/ALK fusion protein, crizotinib, has recently become a standard second-line treatment for patients with the gene rearrangement and has promise for patients with the ROS1 rearrangement.

    Whether it is a requirement to continue with anti-secretory therapy following anti-Helicobacter therapy in H. pylori positive gastric ulcers is an important question. As gastric ulcers tend to heal more slowly than duodenal ulcers, may be asymptomatic or only causing mild symptoms and success at curing H. pylori with current fist line therapies is 80% at best, clinicians will likely err on the side of caution and continue acid suppressive therapy to ensure healing of gastric ulcers. This is certainly recommended when dealing with bleeding ulcers.

    Abstract Rationale: Tyrosine kinase inhibitors (TKIs) are known to have greater efficacy in epidermal growth factor receptor (EGFR) mutation nonsmall cell lung cancer (NSCLC). However, about 10% of EGFR wild-type (wt) patients respond to TKIs. Patient concerns: Several strategies to increase the efficacy of TKIs in wt NSCLC are the subjects of ongoing investigations. One of them is combining EGFR TKI with intercalated chemotherapy. Diagnoses: We describe a patient with EGFR wt NSCLC, who was found with ovarian and lung metastasis, was treated with pemetrexed and intercalated icotinib. Interventions: In this case, we reported the successful long-term maintenance treatment of a patient with EGFR wt NSCLC with pemetrexed and Icotinib. The patient (40-year-old female) was found with ovarian masses and lung masses. Pathological, immunohistochemical, and amplification refractory mutation system (ARMS) assay examinations of ovarian specimen suggested the expression of metastatic lung adenocarcinoma with wt EGFR. After failure treatment with paclitaxel-carboplatin, the patient received 4 cycles of pemetrexed plus platinum with intercalated icotinib and then remained on pemetrexed and icotinib. Outcomes: A partial response was achieved after the treatment. The patient's condition had remained stable on pemetrexed and icotinib for more than 20 months, with no evidence of progression. Lessons: To our knowledge, this is the first report using the long-term maintenance treatment with pemetrexed and intercalated icotinib in EGFR wt patient. The therapeutic strategies warrant further exploration in selected populations of NSCLC. PMID:28816950

    Q-switched Nd: YAG laser is the most effective laser for tattoo removal. Photobiomodulation (PBM) therapy is an alternative method applied to accelerate the wound healing. This paper investigated the effects of PBM therapy using 808 nm diode laser on tattooed skin after laser tattoo removal. Forty-five rats were selected and tattooed with black ink on their dorsal, and then distributed into three groups. G0 was received non-laser irradiation. G1 was treated by laser tattoo removal using 1064 nm with energy density of 3.4 J/cm 2 without PBM therapy, while G2 was treated daily with PBM therapy using 808 nm diode laser of 5 J/cm 2 after a single session of laser tattoo removal. The effects of tattoo removal and healing progress of the wound were analyzed using histological studies. Findings showed 808 nm laser promotes the healing process through enhancing epithelialization and collagen deposition. Moreover, PBM therapy stimulated immune cells to improve phagocytosis process for removing the tattoo ink fragments effectively. The PBM therapy treated group was capable of improving the healing process and increasing the quality of skin following the laser tattoo removal. It was also found that stimulation of cellular function by PBM therapy increased tattoo clearance efficiency. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Full Text Available Background – Platinum based therapy in combination with 5-fluorouracil with cetuximab has shown the best survival in pts with recurrent/metastatic squamous cell carcinoma of the head and neck (R/M SCCHN. The purpose of this study is to evaluate the efficacy and tolerability of carboplatin, pemetrexed and to assess differential outcomes in patients with oropharyngeal primary and HPV related disease.Patients and Methods –The charts of consecutive patients with R/M SCCHN were reviewed. All patients receiving at least 1 cycle of the 2-drug regimen (pemetrexed 500 mg/m2, carboplatin area under the curve of 5 intravenously, were included for assessment of response, safety, toxicity and survival.Results - A total of 86 patients received this regimen between January 2008 and December 2012, of which, 63 were included in this analysis. Forty one percent (26 of the patients had cancers of the oropharynx, and of those, 50% had HPV positive disease, 32% (20 had cancers of the larynx and 24% (15 of the oral cavity. Median number of cycles administered was 4 (range 1-14 cycles with 50% of the patients receiving 4 or more cycles. Half the patients achieved stable disease as their best response, 8% (5 attained a partial response, 24% progressed on therapy and the remaining patients (12 could not have their response assessed.On the basis of Kaplan Meier analysis, median progression free survival (PFS was 5.1 months (95% CI 3.2, 6.2 and median overall survival (OS was 9.4 months (95% CI 4.3, 13.1. Among pts with oropharyngeal primary (n=26, median PFS was 6.4 months (95% CI 2.8, 7.9 and median OS was 16.6 months (95% CI 9.6, 19.5. Among HPV+ pts (n=13, median PFS was 7.0 months (95% CI 4.8, ne and median OS was 17.1 months (95% CI 11.2, 21.7. Conclusion: Combination carboplatin-pemetrexed is an effective and well tolerated treatment, associated with a median PFS of 5.1 months and a clinical benefit in at least 57% of the patients treated.

    Thailand does not currently require Budget Impact Analysis (BIA) assessment. The present study aimed to estimate the annual drug cost and the incremental impact on the hospital pharmaceutical budget of the introduction of pemetrexed to a Thai teaching hospital. The budget impact model was conducted in accordance with the Guidelines for preparing submissions to the Pharmaceutical Benefits Advisory Committee (PBAC). The model variables consisted of number of patients, growth rate of lung cancer, uptake rate of pemetrexed over time, unit prices of drugs, and the length and cost of treatment. Sensitivity analysis was performed to determine changes in budgetary impact due to variation of parameters or assumptions in the model. The introduction of pemetrexed was estimated to cause considerable costs for the teaching hospital. In the base-case analysis, the incremental costs were estimated at 8,553,984 Baht in the first year increasing to 12, 118, 144 Baht, 17,820,800 Baht and 17,820,800 Baht in the following years. The 4-year net budgetary impact was 20,154,480 Baht or approximately 127,560 Baht per patient. Sensitivity analyses found that number of treatment cycles andproportion of patients assumed to be treated with pemetrexed were the two most important influencing factors in the model. New costly innovative interventions should be evaluated using the BIA model to determine whether they are affordable. The Thai government should consider requiring the BIA study as one of the requirements for drug submission to assist in the determination of listing and subsidizing decision for medicines.

    Purpose Cancer and Leukemia Group B conducted a randomized phase II trial to investigate two novel chemotherapy regimens in combination with concurrent thoracic radiation therapy (TRT). Patients and Methods Patients with unresectable stage III non–small-cell lung cancer (NSCLC) were randomly assigned to carboplatin (area under the curve, 5) and pemetrexed (500 mg/m2) every 21 days for four cycles and TRT (70 Gy; arm A) or the same treatment with cetuximab administered concurrent only with TRT (arm B). Patients in both arms received up to four cycles of pemetrexed as consolidation therapy. The primary end point was the 18-month overall survival (OS) rate; if the 18-month OS rate was ≥ 55%, the regimen(s) would be considered for further study. Results Of the 101 eligible patients enrolled (48 in arm A and 53 in arm B), 60% were male; the median age was 66 years (range, 32 to 81 years); 44% and 35% had adenocarcinoma and squamous carcinoma, respectively; and more patients enrolled onto arm A compared with arm B had a performance status of 0 (58% v 34%, respectively; P = .04). The 18-month OS rate was 58% (95% CI, 46% to 74%) in arm A and 54% (95% CI, 42% to 70%) in arm B. No significant difference in OS between patients with squamous and nonsquamous NSCLC was observed (P = .667). The toxicities observed were consistent with toxicities associated with concurrent chemoradiotherapy. Conclusion The combination of pemetrexed, carboplatin, and TRT met the prespecified criteria for further evaluation. This regimen should be studied further in patients with locally advanced unresectable nonsquamous NSCLC. PMID:21747084

    To evaluate the effect of improvement in the control grade of intermittent exotropia using part-time occlusion therapy on the final postoperative outcome. Control of intermittent exotropia was graded as good, fair, or poor in 89 consecutive patients with intermittent exotropia during their first visit. The patients were reevaluated after part-time preoperative occlusion therapy and divided into two groups (improvement and no improvement) according to whether they showed improvement in control grade. The surgical success rate was compared retrospectively between the two groups. The mean angle of deviation on the first visit was 27.61 ± 5.40 prism diopters (PD) at distance and 29.82 ± 5.28 PD at near. There were significant improvements in the angles of deviation for distance (26.17 ± 5.09 PD) and near (27.26 ± 5.56 PD) after part-time occlusion (both P Part-time occlusion therapy improves the control grade of intermittent exotropia, leading to a better likelihood of successful surgery and a reduction of the angles of deviation for distance and near.

    Introduction: Yttrium-90 (Y-90) labeled anti-CD20 monoclonal antibody (ibritumomab tiuxetan or Zevalin TM ) is a novel therapy for patients with relapsed CD20+ B-cell non-Hodgkin's lymphoma (NHL). Patients treated with Zevalin radioimmunotherapy (RIT) are limited from higher doses due to transient and reversible platelet and neutrophil suppression. Patients with indolent NHL who relapse or are refractory to chemotherapy have a 70-80% overall response rate and a 20-30% complete response rate when treated with Zevalin RIT. Therefore additional treatment is required in a minority of patients shortly after Zevalin therapy and in many others at relapse. Relapsed patients are generally treated with chemotherapy alone or high dose chemotherapy followed by autologous transplantation. We wanted to evaluate the ability of patients to tolerate subsequent therapy given at relapse following Zevalin RIT. Methods: We had 58 patients who relapsed after receiving Zevalin RIT and later received additional therapy. The clinical records and lab results were reviewed and compared with a matched control group of patients treated prior to Zevalin availability who received chemotherapy without prior Zevalin RIT. Results: The toxicity in 58 patients treated with Zevalin RIT and subsequent therapy was not significantly different from the control group who did not receive Zevalin RIT. Patients had a median of two subsequent therapies (range, 1-7) after Zevalin. Twenty eight percent required blood cell growth factor support with subsequent chemotherapy and 2 patients required reductions from the standard chemotherapy doses due to prolonged myelosuppression. Eight patients subsequently had successful autologous hematologic stem cell transplant with cells collected after Zevalin. Thirteen of the 58 patients (28%) treated with standard dose chemotherapy were hospitalized for neutropenic fever or thrombocytopenia. Conclusions: Chemotherapy or high dose chemotherapy with autologous transplantation

Digital polymerase chain reaction (PCR is a promising procedure for the detection of mutant alleles in plasma of cancer patients.Methods: This prospective study enrolled patients with NSCLC and known epidermal growth factor receptor (EGFR mutations and who had experienced disease progression during ongoing EGFR-tyrosine kinase inhibitor (TKI therapy. Eligible patients received daily gefitinib and either pemetrexed or S-1 every 3 weeks until disease progression or the development of unacceptable toxicity. Peripheral blood was collected before and after the combination therapy for digital PCR and hepatocyte growth factor measurement.Results: From May 2012 to January 2014, nine patients with a median age of 67 (range 52–80 years were enrolled. Patterns of disease progression during adjacent EGFR-TKI therapy were acquired resistance, observed in seven patients, and primary resistance, observed in two patients. Known EGFR mutations were detected in plasma samples of six (67% patients at study enrollment. Of these, T790M mutation was concurrently detected in three (50% patients

    Full Text Available OBJECTIVES: to compare costs of pemetrexed versus docetaxel in patients with non-small cell lung cancer previously treated with chemotherapy paying special attention to the adverse events. MATERIALS AND METHODS: a cost analysis was carried out performing comparison between pemetrexed and docetaxel. Clinical data (overall survival and resource consumption (chemotherapy drugs, G-CSF, and hospitalizations due to adverse events were obtained from a randomized phase III trial. The economic evaluation was based on direct costs using local Italian unit costs (euro 2005. The perspective was the National Health Service’s. RESULTS: the study results showed that mean survival of pemetrexed (8,3 months; 0,69 years was higher than mean survival of docetaxel (7,9 months; 0,66 years. The mean cost of treatment with pemetrexed was 8.684,26 euros and with docetaxel was 6.182,87 euros. This difference was nearly offset by the difference in the costs of adverse events: the mean cost of adverse events due to chemotherapy treatment with pemetrexed (493,93 euros turned out to be lower than with docetaxel (2.394,34 euros. CONCLUSION: the present cost-analysis could be a stable ground for a further cost-utility analysis, aimed at reaching a more cost-effectiveness management of the chemotherapy-related adverse effects in patients with NSCLC.

    A combination of pemetrexed and cisplatin has been shown to improve the outcome in patients with malignant pleural mesothelioma (MPM), however, there is a great heterogeneity in treatment response among patients. The aim of our study was to evaluate the influence of polymorphisms in folate pathway and transporter genes on pemetrexed treatment outcome in Slovenian patients with MPM. MPM patients treated with pemetrexed in the course of a prospective randomized clinical trial were genotyped for nineteen polymorphisms in five genes of folate pathway and six transporter genes. Logistic regression was used to assess the influence of polymorphisms on treatment efficacy and toxicity, while Cox regression was used to determine their influence on progression-free and overall survival. Patients with at least one polymorphic MTHFD1 rs2236225 allele had a significantly lower response rate (p = 0.005; odds ratio [OR] = 0.12; 95% confidence interval [CI] = 0.03−0.54) and shorter progression-free survival (p = 0.032; hazard ratio [HR] = 3.10; 95% CI = 1.10−8.74) than non-carriers. Polymorphisms in transporter genes did not influence survival; however, several were associated with toxicity. Liver toxicity was significantly lower in carriers of polymorphic ABCC2 rs2273697 (p = 0.028; OR = 0.23; 95% CI = 0.06−0.85), SLCO1B1 rs4149056 (p = 0.028; OR = 0.23; 95% CI = 0.06−0.85) and rs11045879 (p = 0.014; OR = 0.18; 95% CI = 0.05−0.71) alleles compared to non-carriers, as well as in patients with SLCO1B1 GCAC haplotype (p = 0.048; OR = 0.17; 95% CI = 0.03−0.98). Gastrointestinal toxicity was much more common in patients with polymorphic ABCC2 rs717620 allele (p = 0.004; OR = 10.67; 95% CI = 2.15−52.85) and ABCC2 CAG haplotype (p = 0.006; OR = 5.67; 95% CI = 1.64−19.66). MTHFD1 polymorphism affected treatment response and survival, while polymorphisms in ABCC2 and SLCO1B1 transporter genes influenced the risk for toxicity. These polymorphisms could serve as potential

Methods 25 patients with IIIa lung adenocarcinoma undergoing lobectemy or pneumonectomy with mediastinal lymphadenectomy after induction bevacizumab (Bev plus pemetrexed/carboplatin (PC were selected. Toxicity of chemotherapy and postoperative complications were analyzed. Results Grade 3 or 4 neoadjuvant-related adverse events included fatigue (3 patients, neutropenia (3 patients, hypertension (1 patient. The adverse events thought to be related to bevacizumab included epistaxis in 2 patients (grade 1: 1; grade 2: 1 and hypertension in 3 patients (grade 1: 2; grade 3: 1. Postoperative complications included pneumonia in 2 patients, bronchial stump insufficiency in 1 case, atelectasis in 2 cases, and arrhythmia in 1 case. Hemorrhage events, thromboembolic events and wound-healing problems were not observed in the perioperative period. Conclusion The treatment modality of neoadjuvant Bev-PC appears to be safe and tolerant in patients with stage IIIa lung adenocarcinoma.

    Virginie Frings

    Full Text Available OBJECTIVES: Pemetrexed is a thymidylate synthase (TS inhibitor and is effective in non-small cell lung cancer (NSCLC. 3'-deoxy-3'-[¹⁸F]fluorothymidine (¹⁸F-FLT, a proliferation marker, could potentially identify tumor specific TS-inhibition. The aim of this study was to investigate the effect of pemetrexed-induced TS-inhibition on ¹⁸F-FLT uptake 4 hours after pemetrexed administration in metastatic NSCLC patients. METHODS: Fourteen NSCLC patients underwent dynamic ¹⁸F-FLT positron emission tomography (PET scans at baseline and 4 hours after the first dose of pemetrexed. Volumes of interest were defined with a 41%, 50% and 70% threshold of the maximum pixel. Kinetic analysis and simplified measures were performed. At one, two, four and six hours after pemetrexed, plasma deoxyuridine was measured as systemic indicator of TS-inhibition. Tumor response measured with response evaluation criteria in solid tumors (RECIST, time to progression (TTP and overall survival (OS were determined. RESULTS: Eleven patients had evaluable ¹⁸F-FLT PET scans at baseline and 4 hours after pemetrexed. Two patients had increased ¹⁸F-FLT uptake of 35% and 31% after pemetrexed, whereas two other patients had decreased uptake of 31%. In the remaining seven patients ¹⁸F-FLT uptake did not change beyond test-retest borders. In all patients deoxyuridine levels raised after administration of pemetrexed, implicating pemetrexed-induced TS-inhibition. ¹⁸F-FLT uptake in bone marrow was significantly increased 4 hours after pemetrexed administration. Six weeks after the start of treatment 5 patients had partial response, 4 stable disease and 2 progressive disease. Median TTP was 4.2 months (range 3.0-7.4 months; median OS was 13.0 months (range 5.1-30.8 months. Changes in ¹⁸F-FLT uptake were not predictive for tumor response, TTP or OS. CONCLUSIONS: Measuring TS-inhibition in a clinical setting 4 hours after pemetrexed revealed a non-systematic change in

    Tyrosine kinase inhibitors (TKIs) are known to have greater efficacy in epidermal growth factor receptor (EGFR) mutation nonsmall cell lung cancer (NSCLC). However, about 10% of EGFR wild-type (wt) patients respond to TKIs. Several strategies to increase the efficacy of TKIs in wt NSCLC are the subjects of ongoing investigations. One of them is combining EGFR TKI with intercalated chemotherapy. We describe a patient with EGFR wt NSCLC, who was found with ovarian and lung metastasis, was treated with pemetrexed and intercalated icotinib. In this case, we reported the successful long-term maintenance treatment of a patient with EGFR wt NSCLC with pemetrexed and Icotinib. The patient (40-year-old female) was found with ovarian masses and lung masses. Pathological, immunohistochemical, and amplification refractory mutation system (ARMS) assay examinations of ovarian specimen suggested the expression of metastatic lung adenocarcinoma with wt EGFR. After failure treatment with paclitaxel-carboplatin, the patient received 4 cycles of pemetrexed plus platinum with intercalated icotinib and then remained on pemetrexed and icotinib. A partial response was achieved after the treatment. The patient's condition had remained stable on pemetrexed and icotinib for more than 20 months, with no evidence of progression. To our knowledge, this is the first report using the long-term maintenance treatment with pemetrexed and intercalated icotinib in EGFR wt patient. The therapeutic strategies warrant further exploration in selected populations of NSCLC.

    Expert guidelines recommend non-pharmacologic treatments and non-opioid medications for chronic pain and recommend against initiating long-term opioid therapy (LTOT). We examined whether veterans with incident chronic pain receiving care at facilities with greater utilization of non-pharmacologic treatments and non-opioid medications are less likely to initiate LTOT. Retrospective cohort study PARTICIPANTS: Veterans receiving primary care from a Veterans Health Administration facility with incident chronic pain between 1/1/2010 and 12/31/2015 based on either of 2 criteria: (1) persistent moderate-to-severe patient-reported pain and (2) diagnoses "likely to represent" chronic pain. The independent variable was facility-level utilization of pain-related treatment modalities (non-pharmacologic, non-opioid medications, LTOT) in the prior calendar year. The dependent variable was patient-level initiation of LTOT (≥ 90 days within 365 days) in the subsequent year, adjusting for patient characteristics. Among 1,094,569 veterans with incident chronic pain from 2010 to 2015, there was wide facility-level variation in utilization of 10 pain-related treatment modalities, including initiation of LTOT (median, 16%; range, 5-32%). Veterans receiving care at facilities with greater utilization of non-pharmacologic treatments were less likely to initiate LTOT in the year following incident chronic pain. Conversely, veterans receiving care at facilities with greater non-opioid and opioid medication utilization were more likely to initiate LTOT; this association was strongest for past year facility-level LTOT initiation (adjusted rate ratio, 2.10; 95% confidence interval, 2.06-2.15, top vs. bottom quartile of facility-level LTOT initiation in prior calendar year). Facility-level utilization patterns of non-pharmacologic, non-opioid, and opioid treatments for chronic pain are associated with subsequent patient-level initiation of LTOT among veterans with incident chronic pain

    Malignant pleural mesothelioma is a rare cancer that is typically associated with exposure to asbestos. Patients with malignant pleural mesothelioma have poor outcomes with suboptimal therapeutic options and currently no treatment is curative. The standard frontline treatment, cisplatin plus pemetrexed chemotherapy, has only short and insufficient efficacy, and no validated treatment beyond first-line therapy is available. New therapeutic strategies are therefore needed. The addition of bevacizumab (an anti-VEGF antibody) combined with cisplatin plus pemetrexed has shown some promise. However, immunotherapy, especially immune checkpoint inhibitors, has generated a lot of excitement because of data suggesting the potential value of immune checkpoint inhibitors for patients who have failed chemotherapy. In this Review, we describe immune checkpoint inhibitors, other immunotherapies, targeted therapies, or combinations of novel drugs being investigated in malignant pleural mesothelioma, as well as the issues surrounding the selection of the best candidates for these treatments.

    The present work was to develop lipid drug conjugated (LDC) nanoparticles for the potential oral delivery of pemetrexed diacid (PTX) and evaluation of its in vitro, ex vivo and in vivo potentials. The LDC was prepared by salt formation of PTX with stearic acid and followed by cold homogenization technique to produce the LDC nanoparticles. FTIR analysis of LDC proved the presence of amide bond in LDC powder indicating the conjugation between drug and lipid. LDC nanoparticles was found to have particle size 121.9±1.85nm and zeta potential -51.6mV±1.23 and entrapment efficiency 81.0±0.89%. TEM images revealed spherical morphology and were in corroboration with particle size measurements. Ex vivo gut permeation studies revealed a very good enhancement in permeation of drug present in the LDC as compared to plain drug solution and were confirmed by CLSM. MTT assay conformed significant% toxicity at the end of 24h and 48h. Furthermore, the AUC 0-24 of PTX from the optimized LDC nanoparticels was found to be 4.22 folds higher than that from PTX suspension on oral administration. Thus, LDC has high potential for the oral delivery of PTX in cancer therapy and future prospects for the industrial purpose. Copyright © 2017 Elsevier B.V. All rights reserved.

    The chronic nephropathy is often present in pts with rheumatoid arthritis (RA). In the study the authors retrospectively analyzed the clinical course of the disease and outcomes of subsequent dialysotherapy in a group of pts with RA and end-stage renal disease ESRD. During last 5 years ESRD connected with RA was found in 10 (8 F, 2 M) pts out of 325 chronically dialyzed pts (peritoneal dialysis and hemodialysis) representing 3,1% of pts. The mean age at the initiation of dialysotherapy in these pts was 62,8 +/- 10,2 (range 46-76) years. Mean time from the diagnosis of RA to the start of dialysotherapy was 18,8 +/- 11,6 (range 5-40) years. Earlier the patients were treated with many disease modifying antirheumatic drugs (DMARDS) also with glucocorticosteroids and many nonsteroidal anti-inflammatory drugs. It means that they had rather aggressive type of RA. Amyloidosis was histological confirmed in 6 pts (4 F, 2 M). Peritoneal dialysis (PD) was the first choice therapy in 8 pts (2 on APD, 6 on CAPD). The main complication was increased incidence of peritonitis. 3 pts died on PD after 5, 9, 24 months (respectively) of CAPD treatment. 3 pts were transferred to HD after 5, 15, 18 (respectively) months of CAPD because of recurrent peritonitis. 2 pts up to date continue PD (one 12 months, the second 46 months on CAPD). In 5 pts who needed hemodialysis treatment there have been very serious problems with permanent vascular access formation. All used permanent indwelling catheters (Permcath). We concluded that: occurrence of ESRD in pts with RA was connected with aggressive type of disease. Pts with RA represent a dialysis group that is particularly prone to complications of PD (enteric peritonitis) and HD (vascular access problems). It seems to be connected with secondary vasculitis often found in pts with aggressive type of RA.

    Pemetrexed inhibits folate-dependent enzymes involved in pyrimidine and purine synthesis. Previous studies of genetic variation in these enzymes as predictors of pemetrexed efficacy have yielded inconsistent results. We investigated whether red blood cell (RBC) total folate, a phenotypic rather than genotypic, marker of cellular folate status was associated with the response to pemetrexed-based chemotherapy in advanced nonsquamous non-small-cell lung cancer (NSCLC). We conducted a prospective cohort study of patients with stage IV nonsquamous NSCLC receiving first-line chemotherapy containing pemetrexed. The pretreatment RBC total folate level was quantified using liquid chromatography mass spectrometry. We then compared the objective response rate (ORR) between patients with RBC total folate concentrations greater than and less than an optimal cutoff value determined from the receiver operating characteristic curve. A logistic regression model was used to adjust for age, sex, and the use of bevacizumab. The ORR was 62% (32 of 52 patients). Receiver operating characteristic analysis was used to establish that a RBC total folate cutoff value of 364.6 nM optimally discriminated between pemetrexed responders and nonresponders. Patients with RBC total folate  364.5 nM (P = .01). This difference persisted after adjusting for age, sex, and the use of bevacizumab (odds ratio, 0.07; 95% confidence interval, 0.01-0.57; P = .01). A low pretreatment RBC total folate was associated with an inferior response to pemetrexed-based chemotherapy in stage IV nonsquamous NSCLC. Larger, multicenter studies are needed to validate RBC total folate as a predictive marker of pemetrexed response. Copyright © 2016 Elsevier Inc. All rights reserved.

    Objectives Pemetrexed inhibits folate-dependent enzymes involved in pyrimidine and purine synthesis. Prior studies of genetic variation in these enzymes as predictors of pemetrexed efficacy have yielded inconsistent results. We investigated whether red blood cell (RBC) total folate, a phenotypic rather than genotypic marker of cellular folate status, was associated with response to pemetrexed-based chemotherapy in advanced non-squamous non-small-cell lung cancer (NSCLC). Materials and methods We conducted a prospective cohort study of patients with stage IV non-squamous NSCLC receiving first-line chemotherapy containing pemetrexed. Pretreatment RBC total folate was quantified using liquid chromatography/mass spectrometry. We then compared objective response rate (ORR) between patients with RBC total folate concentrations above and below an optimal cut-off value determined from the receiver operating characteristic (ROC) curve. A logistic regression model was used to adjust for age, sex, and use of bevacizumab. Results The ORR was 62% (32 of 52 patients). ROC analysis was used to establish that a RBC total folate cutoff value of 364.6 nM optimally discriminated between pemetrexed responders and non-responders. Patients with RBC total folate below 364.5 nM had an ORR of 27%, compared to 71% in patients with RBC total folate above this value (p=0.01). This difference persisted after adjusting for age, sex, and use of bevacizumab (OR 0.07, 95% CI 0.01 - 0.57, p=0.01). Conclusions Low pretreatment RBC total folate is associated with inferior response to pemetrexed-based chemotherapy in stage IV non-squamous NSCLC. Larger, multicenter studies are needed to validate RBC total folate as a predictive marker of pemetrexed response. PMID:27863923

    ABCG2 is a potential biomarker causing multidrug resistance (MDR) in Non-Small Cell Lung Cancer (NSCLC). We conducted this study to investigate whether Icotinib, a small-molecule inhibitor of EGFR tyrosine kinase, could interact with ABCG2 transporter in NSCLC. Our results showed that Icotinib reversed ABCG2-mediated MDR by antagonizing the drug efflux function of ABCG2. Icotinib stimulated the ATPase activity in a concentration-dependent manner and inhibited the photolabeling of ABCG2 with [125I]-Iodoarylazidoprazosin, demonstrating that it interacts at the drug-binding pocket. Homology modeling predicted the binding conformation of Icotinib at Asn629 centroid-based grid of ABCG2. However, Icotinib at reversal concentration did not affect the expression levels of AKT and ABCG2. Furthermore, a combination of Icotinib and topotecan exhibited significant synergistic anticancer activity against NCI-H460/MX20 tumor xenografts. However, the inhibition of transport activity of ABCG2 was insufficient to overcome pemetrexed resistance in NCI-H460/MX20 cells, which was due to the co-upregulated thymidylate synthase (TS) and ABCG2 expression. This is the first report to show that the up-regulation of TS in ABCG2-overexpressing cell line NCI-H460/MX20 may play a role of resistance to pemetrexate. Our findings suggested different possible strategies of overcoming the resistance of topotecan and pemetrexed in the NSCLC patients.

    Full Text Available Abstract Background Second-line treatment of advanced non-small-cell lung cancer (NSCLC improves overall survival. There is a lack of data regarding the impact on patients' overall health condition. This prospective, non-interventional study evaluated performance status (PS and health-related quality of life (HR-QoL during second-line pemetrexed treatment in routine clinical practice. Methods Stage III/IV NSCLC patients who initiated second-line pemetrexed (standard vitamin and dexamethasone supplementation were observed for a maximum of 9 treatment cycles. The primary objective was to evaluate the proportion of patients achieving improvement of Karnofsky Index (KI of ≥ 10% (absolute or maintaining KI ≥ 80% after the second treatment cycle ("KI benefit response". HR-QoL was self-rated using the EuroQoL-5D questionnaire (EQ-5D. Factors potentially associated with KI benefit response were evaluated using logistic regression models. Results Of 521 eligible patients (73.5% Stage IV, median age 66.3 yrs, 36.1% ≥ 70 yrs, 62.0% with KI ≥ 80%, 471 (90.4% completed at least 2 treatment cycles. 58.0% (95%CI 53.6%;62.2% achieved KI benefit response after the second cycle. Patients with baseline KI ≥ 80%, no Grade 3/4 toxicities during the first 2 cycles, or combination regimen as prior first-line therapy were more likely to achieve a KI benefit response. EQ-5D scores improved over time. Grade 3/4 toxicities were reported in 23.8% of patients (mainly fatigue/asthenia 15.9%, neutropenia 8.7%. Conclusions In this large prospective, non-interventional study of second-line pemetrexed treatment in patients with advanced NSCLC, including 36% elderly patients ( ≥ 70 years, physician-rated PS and self-rated HR-QoL were maintained or improved in the majority of patients.

    The safety and effectiveness of pemetrexed(PEM)in patients with non-small cell lung cancer(NSCLC)were reviewed using data from post-marketing surveillance. Among 699 patients registered from June 2009 to May 2010, 683 patients were analyzed(343, first-line therapy: 340, second-line therapy or beyond). Patient backgrounds were as follows: median age=65 years(16.1%B75 years old); 64.7% male; 91.9% performance status 0-1; 83.2% Stage IV; 99.0% non-squamous cell cancer. Also, 86% of the first-line and 20% of the second-line cohort were receiving a concomitant anti-cancer drug(mostly platinum agents). The incidence rate of adverse drug reactions(ADR)was 76.7%, including serious cases(18.0%). The most common ADRs were decreased white blood cell count(26.8%), decreased neutrophil count(25.3%), anemia(19.2%), decreased platelet count(17.0%), and nausea(23.0%). The incidence of interstitial lung disease, which is a concern during chemotherapy, was 2.6%. Peripheral neuropathy and alopecia, events influencing a patient's quality of life, were less than 1%. The estimated median survival time was 23.2 months[95%CI: 19.8 months-not calculable]in the first-line cohort, and 11.8 months[95% CI: 10.5-13.7 months]in the B second-line cohort. The surveillance results showed no apparent difference in total ADRs in this current study compared to the safety profile established in clinical trials previously conducted in Japan and overseas. These results demonstrate the safety and effectiveness of PEM treatment for NSCLC patients in daily clinical settings.

    This phase I study investigates the feasibility of carboplatin plus dose-dense (q2-week) pemetrexed given concurrently with radiotherapy (XRT) for locally advanced and oligometastatic non-small cell lung cancer (NSCLC). Eligible patients had Stage III or IV (oligometastatic) NSCLC. Patients received XRT to 63 Gy in standard fractionation. Patients received concurrent carboplatin (AUC = 6) during weeks 1 and 5 of XRT, and pemetrexed during weeks 1, 3, 5, and 7 of XRT. The starting dose level (level 1) of pemetrexed was 300 mg/m 2 . Following the finding of dose limiting toxicity (DLT) in dose level 1, an amended dose level (level 1A) continued pemetrexed at 300 mg/m 2 , but with involved field radiation instead of extended nodal irradiation. Consolidation consisted of carboplatin (AUC = 6) and pemetrexed (500 mg/m 2 ) q3 weeks × 2 -3 cycles. Eighteen patients were enrolled. Fourteen patients are evaluable for toxicity analysis. Of the initial 6 patients treated on dose level 1, two experienced DLTs (one grade 4 sepsis, one prolonged grade 3 esophagitis). There was one DLT (grade 5 pneumonitis) in the 8 patients treated on dose level 1A. In 16 patients evaluable for response (4 with oligometastatic stage IV disease and 12 with stage III disease), the median follow-up time is 17.8 months. Thirteen of 16 patients had in field local regional response. The actuarial median survival time was 28.6 months in all patients and 34.7 months (estimated) in stage III patients. Concurrent carboplatin with dose-dense (q2week) pemetrexed at 300 mg/m 2 with involved field XRT is feasible and encouraging in patients with locally advanced and oligometastatic NSCLC.

    Research suggests psychological therapy as the treatment of choice for individuals diagnosed with NEAD. This study explored the experience of adjusting to a diagnosis of NEAD and engagement with therapy through a qualitative methodology. Semi-structured interviews were conducted with 6 people with a diagnosis of NEAD and analysed using thematic analysis. Six master-themes were generated, with four discussed. Two themes were not discussed due to previous coverage in the literature and their less direct relevance to the service context. Theme 1: 'understanding NEAD' incorporated participants' evolving understanding of the diagnosis and their reflections on this. Theme 2: 'I can't deal with you' centres on participants' accounts of relationships with professionals in the context of NEAD. Theme 3: 'experiences of psychological therapy' reflected participants' experience of being referred to psychology and gaining a deeper understanding of themselves through therapy. Theme 4: 'adjusting to life with NEAD' explores participants' views on living with NEAD and their expectations for the future. This study extended previous research by highlighting the impact of how the diagnosis is received and understood on engagement in therapy. Improving awareness of NEAD amongst healthcare professionals is of key importance in reducing stigma and encouraging engagement in therapy. Copyright © 2014 British Epilepsy Association.

    Enzastaurin is an oral serine/threonine kinase inhibitor that targets protein kinase C-beta (PKC-β) and the phosphatidylinositol-3-kinase/AKT pathway. This trial assessed pemetrexed-carboplatin ± enzastaurin to docetaxel-carboplatin in advanced non-small cell lung cancer. Patients with stage IIIB (with pleural effusion) or IV non-small cell lung cancer and performance status 0 or 1 were randomized to one of the three arms: (A) pemetrexed 500 mg/m and carboplatin area under the curve 6 once every 3 weeks for up to 6 cycles with a loading dose of enzastaurin 1125 or 1200 mg followed by 500 mg daily until disease progression, (B) the same regimen of pemetrexed-carboplatin without enzastaurin, or (C) docetaxel 75 mg/m and carboplatin area under the curve 6 once every 3 weeks for up to six cycles. The primary end point was time to disease progression (TTP). Between March 2006 and May 2008, 218 patients were randomized. Median TTP was 4.6 months for pemetrexed-carboplatin-enzastaurin, 6.0 months for pemetrexed-carboplatin, and 4.1 months for docetaxel-carboplatin (differences not significant). Median survival was 7.2 months for pemetrexed-carboplatin-enzastaurin, 12.7 months for pemetrexed-carboplatin, and 9.2 months for docetaxel-carboplatin (log-rank p = 0.05). Compared with the other arms, docetaxel-carboplatin was associated with lower rates of grade 3 thrombocytopenia and anemia but a higher rate of grade 3 or 4 febrile neutropenia. There was no difference in TTP between the three arms, but survival was longer with pemetrexed-carboplatin compared with docetaxel-carboplatin. Enzastaurin did not add to the activity of pemetrexed-carboplatin.

    Erlotinib and pemetrexed have been approved for the second-line treatment of non-small cell lung cancer (NSCLC). These two agents have different mechanisms of action. Combined treatment with erlotinib and pemetrexed could potentially augment the antitumor activity of either agent alone. In the present study, we investigated the safety profile of combined administration of the two agents in pretreated NSCLC patients. A phase I dose-finding study (Trial registration: UMIN000002900) was performed in patients with stage III/IV nonsquamous NSCLC whose disease had progressed on or after receiving first-line chemotherapy. Patients received 500 mg/m 2 of pemetrexed intravenously every 21 days and erlotinib (100 mg at Level 1 and 150 mg at Level 2) orally on days 2–16. Twelve patients, nine males and three females, were recruited. Patient characteristics included a median age of 66 years (range, 48–78 years), stage IV disease (nine cases), adenocarcinoma (seven cases) and activating mutation-positives in the epidermal growth factor receptor gene (two cases). Treatment was well-tolerated, and the recommended dose of erlotinib was fixed at 150 mg. Dose-limiting toxicities were experienced in three patients and included: grade 3 elevation of serum alanine aminotransferase, repetitive grade 4 neutropenia that required reduction of the second dose of pemetrexed and grade 3 diarrhea. No patient experienced drug-induced interstitial lung disease. Three patients achieved a partial response and stable disease was maintained in five patients. Combination chemotherapy of intermittent erlotinib with pemetrexed was well-tolerated, with promising efficacy against pretreated advanced nonsquamous NSCLC

    Full Text Available Abstract Background Metastatic melanoma is a lethal skin cancer and its incidence is rising every year. It represents a challenge for oncologist, as the current treatment options are non-curative in the majority of cases; therefore, the effort to find and/or develop novel compounds is mandatory. Pemetrexed (Alimta®, MTA is a multitarget antifolate that inhibits folate-dependent enzymes: thymidylate synthase, dihydrofolate reductase and glycinamide ribonucleotide formyltransferase, required for de novo synthesis of nucleotides for DNA replication. It is currently used in the treatment of mesothelioma and non-small cell lung cancer (NSCLC, and has shown clinical activity in other tumors such as breast, colorectal, bladder, cervical, gastric and pancreatic cancer. However, its effect in human melanoma has not been studied yet. Results In the current work we studied the effect of MTA on four human melanoma cell lines A375, Hs294T, HT144 and MeWo and in two NSCLC cell lines H1299 and Calu-3. We have found that MTA induces DNA damage, S-phase cell cycle arrest, and caspase- dependent and –independent apoptosis. We show that an increment of the intracellular reactive oxygen species (ROS and p53 is required for MTA-induced cytotoxicity by utilizing N-Acetyl-L-Cysteine (NAC to blockage of ROS and p53-defective H1299 NSCLC cell line. Pretreatment of melanoma cells with NAC significantly decreased the DNA damage, p53 up-regulation and cytotoxic effect of MTA. MTA was able to induce p53 expression leading to up-regulation of p53-dependent genes Mcl-1 and PIDD, followed by a postranscriptional regulation of Mcl-1 improving apoptosis. Conclusions We found that MTA induced DNA damage and mitochondrial-mediated apoptosis in human melanoma cells in vitro and that the associated apoptosis was both caspase-dependent and –independent and p53-mediated. Our data suggest that MTA may be of therapeutic relevance for the future treatment of human malignant melanoma.

  14. Differential effect of IP- and IV-injected nitrogen mustard on subsequently-irradiated intestinal crypts: implications for 'dose-effect factors' predicted by experimental, combined modality therapy

    In experimental chemotherapy-radiotherapy, cytotoxic drugs are almost invariably injected by the intraperitoneal (IP) route. This contrasts with normal clinical practice, which is to employ the intravenous (IV) route. We have used a clonogenic assay of gastrointestinal (GI) injury in mice to show that a given administered dose of nitrogen mustard (HN 2 ), injected IP, results in a much greater reduction in the subsequent radiation dose required to achieve an isoeffect, than if the drug is injected IV. At an administered dose of 3.5 mg kg -1 of HN 2 (the animal LDsub(10/30) for IP injection), the radiation dose-reduction factor for 10% survival of intestinal crypts, was 1.94 for IP HN 2 and only 1.28 for IV HN 2 . Even the grossly-equitoxic (mouse LDsub(10/30)) dose of IV HN 2 resulted in a smaller predicted radiation dose reduction for GI injury, by a factor of 1.45. The validity of using the IP route in combined chemotherapy-radiotherapy studies designed to generate quantitative estimates of toxicity is discussed. (author)

    Purpose: Aim of this study was to optimize the magnetic field strengths of two quadrupole magnets in a particle therapy facility in order to obtain a beam quality suitable for spot beam scanning. Methods: The particle transport through an ion-optic system of a particle therapy facility consisting of the beam tube, two quadrupole magnets and a beam monitor system was calculated with the help of Matlab by using matrices that solve the equation of motion of a charged particle in a magnetic field and field-free region, respectively. The magnetic field strengths were optimized in order to obtain a circular and thin beam spot at the iso-center of the therapy facility. These optimized field strengths were subsequently transferred to the Monte-Carlo code FLUKA and the transport of 80 MeV/u C12-ions through this ion-optic system was calculated by using a user-routine to implement magnetic fields. The fluence along the beam-axis and at the iso-center was evaluated. Results: The magnetic field strengths could be optimized by using Matlab and transferred to the Monte-Carlo code FLUKA. The implementation via a user-routine was successful. Analyzing the fluence-pattern along the beam-axis the characteristic focusing and de-focusing effects of the quadrupole magnets could be reproduced. Furthermore the beam spot at the iso-center was circular and significantly thinner compared to an unfocused beam. Conclusion: In this study a Matlab tool was developed to optimize magnetic field strengths for an ion-optic system consisting of two quadrupole magnets as part of a particle therapy facility. These magnetic field strengths could subsequently be transferred to and implemented in the Monte-Carlo code FLUKA to simulate the particle transport through this optimized ion-optic system

    The main objective of this study was to evaluate the safety of second-line pemetrexed in Stage IIIB or IV NSCLC. Overall, 95 patients received pemetrexed 500 mg/m 2 i.v. over Day 1 of a 21-day cycle. Patients also received oral dexamethasone, oral folic acid and i.m. vitamin B12 supplementation to reduce toxicity. NCI CTC 2.0 was used to rate toxicity. All the adverse events were graded in terms of severity and relation to study treatment. Dose was reduced in case of toxicity and treatment was delayed for up to 42 days from Day 1 of any cycle to allow recovering from study drug-related toxicities. Tumor response was measured using the RECIST criteria. Patients received a median number of 4 cycles and 97.8% of the planned dose. Overall, 75 patients (78.9% of treated) reported at least one adverse event: 34 (35.8%) had grade 3 as worst grade and only 5 (5.2%) had grade 4. Drug-related events occurred in 57.9% of patients. Neutropenia (8.4%) and leukopenia (6.3 %) were the most common grade 3/4 hematological toxicities. Grade 3 anemia and thrombocytopenia were reported in 3.2% and 2.1% of patients, respectively. Diarrhea (6.3%), fatigue (3.2%) and dyspnea (3.2%) were the most common grade 3/4 non-hematological toxicities. The most common drug-related toxicities (any grade) were pyrexia (11.6%), vomiting, nausea, diarrhea and asthenia (9.5%) and fatigue (8.4%). Tumor Response Rate (CR/PR) in treated patients was 9.2%. The survival at 4.5 months (median follow-up) was 79% and the median PFS was 3.1 months. Twenty patients (21.1%) died mainly because of disease progression. Patients with locally advanced or metastatic NSCLC could benefit from second-line pemetrexed, with a low incidence of hematological and non-hematological toxicities

    Occupational and physical therapy (OT/PT) services seek to reduce morbidity, mortality, and improve the quality of life of individuals; however, little is known about the needs and use of OT/PT for older adults with cancer. The goal of this study was to describe the functional deficits and their associations with other factors, and to examine the use of OT/PT after a noted functional deficit. This study analyzed data from an institution-based registry that included geriatric assessments of older adults with cancer linked to billing claims data. Logistic regression was used to model predictors of functional deficits. Use of OT/PT was determined and validated with medical chart review. 529 patients with cancer, a median age of 71, 78% were female, 87% Caucasian, 57% married, 53% post-secondary education, and 63% with breast cancer were included. In a multivariable model, the odds of having any functional deficits increased with age [5 year OR: 1.31, 95% CI: (1.10, 1.57)] were higher for those with a high school diploma versus those with advanced degrees [OR: 1.66, 95% CI: (1.00, 2.77)] and were higher for patients with comorbidities [OR: 1.15, 95% CI: (1.10, 1.21)]. Of patients with functional deficits only 9% (10/111) received OT/PT within 12 months of a noted deficit. The odds of having any potentially modifiable functional deficit were higher in patients with increasing age, comorbid conditions, and with less than a college degree. Few were referred for OT/PT services suggesting major underutilization of these potentially beneficial services. Copyright © 2015 Elsevier Inc. All rights reserved.

    Regorafenib is an oral multitargeted kinase inhibitor with potent antiangiogenic activity. In this phase I trial we evaluated the safety, pharmacokinetics, and efficacy of regorafenib with cisplatin and pemetrexed for patients with advanced nonsquamous non-small-cell lung cancers (nsNSCLCs). Nine patients enrolled before premature termination of the study. Five of 9 (56%) patients had a partial response and the median progression-free survival was 7 months (range, 1.5-15.1 months). Regorafenib had acceptable tolerability and minor pharmacokinetic interactions in combination with standard doses of cisplatin and pemetrexed in patients with advanced nsNSCLCs. The combination of bevacizumab, an antiangiogenesis agent, with cytotoxic chemotherapy improves survival in patients with advanced nonsquamous non-small-cell lung cancers (nsNSCLCs). Regorafenib is an oral multitargeted kinase inhibitor with potent antiangiogenic activity that is approved for patients with advanced colorectal cancer and gastrointestinal stromal tumors. In this phase I trial we evaluated the safety, pharmacokinetics (PK), and efficacy of regorafenib with cisplatin and pemetrexed for patients with advanced nsNSCLCs. Chemotherapy-naive patients with advanced nsNSCLCs were treated with regorafenib 60 mg/d continuously and cisplatin 75 mg/m(2) with pemetrexed 500 mg/m(2) once every 21 days for up to 6 cycles. Thereafter, regorafenib with or without pemetrexed could be continued as maintenance. Nine patients enrolled before premature termination of the study because of slow recruitment and a change in the development strategy of regorafenib by the study sponsor. Five patients experienced at least 1 treatment-related Grade 3 adverse event. No Grade 4 or 5 toxicity occurred. Five of 9 (56%) patients had a partial response and the median progression-free survival was 7 months (range, 1.5-15.1 months). Minor PK interactions between regorafenib and chemotherapy were observed. Regorafenib had acceptable

    Non-small cell lung cancer (NSCLC) remains one of the leading causes of cancer related deaths worldwide across both sex. Patients with Advanced -NSCLC (A-NSCLC) do not have curative treatment options, so the primary endpoint of every therapeutic decision aims to prolong survival, improving or maintain a good Quality of Life (QoL). Histology could represent a positive predictive factor for patients with Non squamous NSCLC (Nsq-NSCLC) respect to pemetrexed treatment. Pemetrexed is an antifolate that inhibits primarily thymidylate synthase (TS), together with dihydrofolate reductase and glycinamide ribonucleotide formyl transferase. Pemetrexed in combination with cisplatin is approved in the first line setting and as monotherapy in the switch or continuous maintenance of Non Squamous A-NSCLC. Maintenance therapy is a widely used therapeutic option in other solid and hematologic malignancies, but in the A-NSCLC represent an innovative approach. The rationale in this new setting of patients is based on the evidence that patients who benefit from an initial induction therapy platinum based may benefit from maintenance therapy with the third generation agent dropping the platinum drug after four to six cycles. We can define two types of maintenance therapy: continuation maintenance and switch maintenance. Major results in prolonging Overall Survival (OS) was reported with the continuation maintenance strategy as in the PARAMOUNT trial.

    Pemetrexed, a novel multi-targeted agent established for the treatment of mesothelioma, has been under investigation for other malignancies, and in recent years particularly for non-small-cell lung cancer (NSCLC). In the present trial we investigated pemetrexed in combination with paclitaxel as front-line treatment in advanced or metastatic NSCLC. Our objectives were to determine the response rate, median and overall survival and toxicity. From April 2005 until May 2006, 51 patients with advanced or metastatic NSCLC were enrolled and 48 were considered evaluable. There were 39 males and nine females, median age 62 years (range 37-81 years), one patient stage IIIA N(2), 23 patients, IIIB and 24, stage IV. All patients had a cytologically- or histologically-confirmed diagnosis. Pemetrexed was administered at a standard dose of 500mg/m(2) and paclitaxel at an escalating dose starting at 135mg/m(2), then 150mg/m(2) and ending at a dose of 175mg/m(2); the level was increased every three patients. Both agents were administered on day 1, repeated every 3 weeks for six courses. A 39.6% partial response rate was observed with a median survival of 14 months. Toxicity was mild with 8.3% grade 3 and 4 neutropenia and other very mild hematologic and non-hematologic adverse reactions. The combination of pemetrexed and paclitaxel at doses of 500mg/m(2) and 175mg/m(2), respectively, has been shown to be an effective combination with very limited toxicity.

    Structured Abstract Purpose The addition of bevacizumab, an anti-angiogenesis agent, to cytotoxic chemotherapy improves survival in patients with advanced non-squamous non-small cell lung cancers (nsNSCLCs). Regorafenib is an oral multi-targeted kinase inhibitor with potent anti-angiogenic activity that is approved for patients with advanced colorectal cancer and gastrointestinal stromal tumors. This phase I trial evaluated the safety, pharmacokinetics, and efficacy of regorafenib with cisplatin and pemetrexed for patients with advanced nsNSCLCs. Methods Chemotherapy-naïve patients with advanced nsNSCLCs were treated with regorafenib 60mg/day continuously and cisplatin 75mg/m2 plus pemetrexed 500mg/m2 once every three weeks for up to six cycles. Thereafter, regorafenib with or without pemetrexed could be continued as maintenance. Results Nine patients enrolled prior to premature termination of the study due to slow recruitment and a change in the development strategy of regorafenib by the study sponsor, partially due to slow enrollment. Five patients experienced at least one treatment-related Grade 3 adverse event. No grade 4–5 toxicity occurred. 5 of 9 (56%) patients had a partial response and the median progression-free survival was 7 months (range 1.5–15.1). Minor pharmacokinetic (PK) interactions between regorafenib and chemotherapy were observed. Conclusions Regorafenib had acceptable tolerability and minor PK interactions in combination with standard doses of cisplatin and pemetrexed in patients with advanced nsNSCLCs. Encouraging activity was appreciated in chemotherapy-naïve patients with advanced nsNSCLCs. However, the small number of patients treated limits conclusions that can be drawn from these results.

    Full Text Available Background and objective Platinum-based doublet chemotherapy is still the standard first-line treatment for non-small cell lung cancer (NSCLC. Previous studies have demonstrated that pemetrexed combined with platinum had promising efficacy and safety profile in NSCLC, especially in patients with nonsquamous NSCLC. This trial was conducted to evaluate the efficacy and safety of pemetrexed made in China as first-line treatment. Methods The present study was a randomized, controlled, multicenter clinical trial. Patients were randomly assigned (1:1 to receive cisplatin plus pemetrexed chemotherapy (PC group or gemcitabine plus cisplatin (GC group every 3 weeks. The primary end point was progression free survival (PFS and the secondary end points included 1 year survival rate, objective response rate (ORR, survival without grade 3/4 toxicity (SWT3/4 and safety profile. Results A total of 288 patients from 20 institutions across China were enrolled into the study. Based on the Full Analyses Set (FAS, the PFS was 168 days (5.6 months vs 140 days (4.7 months (P=0.16, one year survival rate was 50.0% vs 54.9% (P=0.47, ORR was 24.4% vs 14.2% (P=0.06 in the PC group and the GC group, respectively; Survival without grade 3/4 toxicity was 11.3 months in GC group vs 8.1 months in PC group (P=0.23. In terms of the safety, side effects were less observed on the PC group (81.95% vs 93.75%, P=0.003. The main side effects included leukopenia, neutropenia, emesis, anemia, thrombopenia. Conclusion The both regimens have similar efficacy as the treatment for advanced nonsquamous NSCLC, but pemetrexed plus cisplatin regimen has better safety profile and seems to have longer PFS, which makes it a new option as the first line setting.

    We conducted a prospective multi-institutional study to determine the feasibility of trimodality therapy (TMT) comprising induction chemotherapy followed by extrapleural pneumonectomy (EPP) and radiation therapy in Japanese patients with malignant pleural mesothelioma (MPM). Major eligibility criteria were histologically confirmed diagnosis of MPM, including clinical subtypes T0-3, N0-2, M0 disease; no prior treatment for the disease; age 20-75 years; Eastern Cooperative Oncology Group performance status 0 or 1; predicted postoperative forced expiratory volume >1000 ml in 1 s; written informed consent. Treatment methods comprised induction chemotherapy using pemetrexed (500 mg/m(2)) plus cisplatin (60 mg/m(2)) for three cycles, followed by EPP and postoperative hemithoracic radiation therapy (54 Gy). Primary endpoints were macroscopic complete resection (MCR) rate for EPP and treatment-related mortality for TMT. Forty-two eligible patients were enrolled: median age 64.5 (range 43-74) years; M:F = 39:3, clinical stage I:II:III = 14:13:15; histological type epithelioid were sarcomatoid; biphasic; others = 28:1:9:4. Of 42 patients, 30 completed EPP with MCR and 17 completed TMT. The trial met the primary endpoints, with an MCR rate of 71 % (30/42) and treatment-related mortality of 9.5 % (4/42). Overall median survival time and 2-year survival rate for 42 registered patients were 19.9 months and 42.9 %, respectively. Two-year relapse-free survival rate of 30 patients who completed EPP with MCR was 37.0 %. This phase II study met the predefined primary endpoints, but its risk/benefit ratio was not satisfactory.

    Self-harm is common in the community with a lifetime prevalence of 13 %. It is associated with an elevated risk of overall mortality and suicide. People who harm themselves are high users of public services. Estimates of the 1-year risk of repetition vary between 5 and 15 % per year. Currently, limited evidence exists on the effectiveness of clinical interventions for young people who engage in self-harm. Recent reviews have failed to demonstrate any effect on reducing repetition of self-harm among adolescents receiving a range of treatment approaches. Family factors are particularly important risk factors associated with fatal and non-fatal self-harm among children and adolescents. Family therapy focuses on the relationships, roles and communication patterns between family members, but there have been relatively few studies of specifically family-focused interventions with this population. The Self-Harm Intervention: Family Therapy (SHIFT) Trial was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme (grant no. 07/33/01) following a commissioned call for this research. SHIFT is a pragmatic, phase III, multicentre, individually randomised, controlled trial comparing Family Therapy (FT) with treatment as usual (TAU) for adolescents aged 11 to 17 who have engaged in at least two episodes of self-harm. Both therapeutic interventions were delivered within the National Health Service (NHS) Child and Adolescent Mental Health Services (CAMHS) in England. Participants and therapists were, of necessity, aware of treatment allocation, but the researchers were blind to the allocations to allow unbiased collection of follow-up data. Primary outcome data (repetition of self-harm leading to hospital attendance 18 months post-randomisation) were collected from the Health and Social Care Information Centre (HSCIC), augmented by directed searches of medical records at Acute Trusts.

    Malignant pleural mesothelioma is an aggressive tumor that has a poor prognosis and is resistant to unimodal approaches. Multimodal treatment has provided encouraging results. Phase II, open-label study of the combination of chemotherapy (pemetrexed 500 mg/m 2 +cisplatin 75 mg/m 2 IV every 21 days × 3 cycles), followed by surgery (en-bloc extrapleural pneumonectomy, 3–8 weeks after chemotherapy) and hemithoracic radiation (total radiation beam 54 Gy, received 4–8 weeks post-surgery). The primary endpoint was event-free survival, defined as the time from enrollment to time of first observation of disease progression, death due to any cause, or early treatment discontinuation. Fifty-four treatment-naïve patients with T1-3 N0-2 malignant pleural mesothelioma were enrolled, 52 (96.3%) completed chemotherapy, 45 (83.3%) underwent surgery, 22 (40.7%) completed the whole treatment including 90-day post-radiation follow-up. The median event-free survival was 6.9 months (95%CI: 5.0-10.5), median overall survival was 15.5 months (95%CI 11.0-NA) while median time-to-tumor response was 4.8 months (95%CI: 2.5-8.0). Eighteen (33.3%) and 13 (24.1%) patients were still event-free after 1 and 2 years, respectively. The most common treatment-emergent adverse events were nausea (63.0%), anemia (51.9%) and hypertension (42.6%). Following two cardiopulmonary radiation-related deaths the protocol was amended (21 [38.9%] patients were already enrolled in the study): the total radiation beam was reduced from 54 Gy to 50.4 Gy and a more accurate selection of patients was recommended. The combination of pemetrexed plus cisplatin followed by surgery and hemithoracic radiation is feasible and has a manageable toxicity profile in carefully selected patients. It may be worthy of further investigation. Clinicaltrial.com registrationID #NCT00087698

    Self-harm in adolescents is common and repetition rates high. There is limited evidence of the effectiveness of interventions to reduce self-harm. To assess the clinical effectiveness and cost-effectiveness of family therapy (FT) compared with treatment as usual (TAU). A pragmatic, multicentre, individually randomised controlled trial of FT compared with TAU. Participants and therapists were aware of treatment allocation; researchers were blind to allocation. Child and Adolescent Mental Health Services (CAMHS) across three English regions. Young people aged 11-17 years who had self-harmed at least twice presenting to CAMHS following self-harm. Eight hundred and thirty-two participants were randomised to manualised FT delivered by trained and supervised family therapists ( n  = 415) or to usual care offered by local CAMHS following self-harm ( n  = 417). Rates of repetition of self-harm leading to hospital attendance 18 months after randomisation. Out of 832 young people, 212 (26.6%) experienced a primary outcome event: 118 out of 415 (28.4%) randomised to FT and 103 out of 417 (24.7%) randomised to TAU. There was no evidence of a statistically significant difference in repetition rates between groups (the hazard ratio for FT compared with TAU was 1.14, 95% confidence interval 0.87 to 1.49; p  = 0.3349). FT was not found to be cost-effective when compared with TAU in the base case and most sensitivity analyses. FT was dominated (less effective and more expensive) in the complete case. However, when young people's and caregivers' quality-adjusted life-year gains were combined, FT incurred higher costs and resulted in better health outcomes than TAU within the National Institute for Health and Care Excellence cost-effectiveness range. Significant interactions with treatment, indicating moderation, were detected for the unemotional subscale on the young person-reported Inventory of Callous-Unemotional Traits ( p  = 0.0104) and the affective involvement

    Malignant pleural mesothelioma (MPM) is a rare malignancy, and pemetrexed/cisplatin (PC) is the gold standard first-line regime. This study evaluated the cost-effectiveness of the addition of bevacizumab to PC (with maintenance bevacizumab) for unresectable MPM based on a phase III trial that showed a survival benefit compared with chemotherapy alone. To estimate the incremental cost-effectiveness ratio (ICER) of the incorporation of bevacizumab, a Markov model based on the MAPS trial, including the disease states of progression-free survival, progressive disease and death, was used. Total costs were calculated from a Chinese payer perspective, and health outcomes were converted into quality-adjusted life year (QALY). Model robustness was explored in sensitivity analyses. The addition of bevacizumab to PC was estimated to increase the cost by $81446.69, with a gain of 0.112 QALYs, resulting in an ICER of $727202.589 per QALY. In both one-way sensitivity and probabilistic sensitivity analyses, the ICER exceeded the commonly accepted willingness-to-pay threshold of 3 times the gross domestic product per capita of China ($23970.00 per QALY). The cost of bevacizumab had the most important impact on the ICER. The combination of bevacizumab with PC chemotherapy is not a cost-effective treatment option for MPM in China. Given its positive clinical value and extremely low incidence of MPM, an appropriate price discount, assistance programs and medical insurance should be considered to make bevacizumab more affordable for this rare patient population.

    Full Text Available To compare the efficacy and toxicities of pemetrexed plus platinum with other platinum regimens in patients with previously untreated advanced non-small cell lung cancer (NSCLC.A meta-analysis was performed using trials identified through PubMed, EMBASE, and Cochrane databases. Two investigators independently assessed the quality of the trials and extracted data. The outcomes included overall survival (OS, progression-free survival (PFS, response rate (RR, and different types of toxicity. Hazard ratios (HRs, odds ratios (ORs and their 95% confidence intervals (CIs were pooled using RevMan software.Four trials involving 2,518 patients with previously untreated advanced NSCLC met the inclusion criteria. Pemetrexed plus platinum chemotherapy (PPC improved survival compared with other platinum-based regimens (PBR in patients with advanced NSCLC (HR = 0.91, 95% CI: 0.83-1.00, p = 0.04, especially in those with non-squamous histology (HR = 0.87, 95% CI: 0.77-0.98, p = 0.02. No statistically significant improvement in either PFS or RR was found in PPC group as compared with PBR group (HR = 1.03, 95% CI: 0.94-1.13, p = 0.57; OR = 1.15, 95% CI: 0.95-1.39, p = 0.15, respectively. Compared with PBR, PPC led to less grade 3-4 neutropenia and leukopenia but more grade 3-4 nausea. However, hematological toxicity analysis revealed significant heterogeneities.Our results suggest that PPC in the first-line setting leads to a significant survival advantage with acceptable toxicities for advanced NSCLC patients, especially those with non-squamous histology, as compared with other PRB. PPC could be considered as the first-line treatment option for advanced NSCLC patients, especially those with non-squamous histology.

    Objective The aim of this study was to prospectively investigate the efficacy and safety profiles of low-dose dasatinib therapy (50 mg once daily). Methods Patients with chronic myeloid leukemia in the chronic phase (CML-CP) who were being treated with low-dose imatinib (≤200 mg/day), but were resistant to this agent were enrolled in the current study (referred to as the LD-CML study). Results There subjects included 9 patients (4 men and 5 women); all were treated with dasatinib at a dose of 50 mg once daily. Among 8 patients who had not experienced major molecular response (MMR; BCR-ABL1 transcript ≤0.1% according to International Scale [IS]) at study enrollment, 5 attained MMR by 12 months. In particular, 3 of 9 patients demonstrated a deep molecular response (DMR; IS ≤0.0069%) by 18 months. Five patients developed lymphocytosis accompanied by cytotoxic lymphocyte predominance. There was no mortality or disease progression, and all continue to receive dasatinib therapy at 18 months with only 2 patients requiring dose reduction. Toxicities were mild-to-moderate, and pleural effusion was observed in 1 patient (grade 1). Conclusion Low-dose dasatinib can attain MMR and DMR without severe toxicity in patients with CML-CP who are unable to achieve MMR with low-dose imatinib. Switching to low-dose dasatinib should therefore be considered for patients in this setting, especially if they are otherwise considering a cessation of treatment. PMID:29033428

    We aimed to evaluate the efficiency and safety of cis/carboplatin plus gemcitabine, which was previously used for mesothelioma but with no recorded proof of its efficiency, compared with cis/carboplatin plus pemetrexed, which is known to be effective in mesothelioma, in comparable historical groups of malignant pleural mesothelioma. One hundred and sixteen patients received cis/carboplatin plus pemetrexed (group 1), while 30 patients received cis/carboplatin plus gemcitabine (group 2) between June 1999 and June 2012. The two groups were compared in terms of median survival and adverse events to chemotherapy. The mean ages of groups 1 and 2 were 60.7 and 60.8 years, respectively. Most of the patients (78.1%) had epithelial type tumors, and 47% of the patients had stage IV disease. There was no difference between the two groups in terms of age, gender, asbestos exposure, histology, stage, Karnofsky performance status, presence of pleurodesis, prophylactic radiotherapy, second-line chemotherapy and median hemoglobin and serum albumin levels. The median survival time from diagnosis to death or the last day of follow up with a 95% confidence interval was 12 ± 0.95 months (95% CI: 10.15-13.85) for group 1 and 11.0 ± 1.09 months (95% CI: 8.85-13.15) for group 2 (Log-Rank: 0.142; p = 0.706). The median survival time from treatment to death or the last day of follow-up with a 95% confidence interval was 11.0 ± 0.99 months (95% CI: 9.06-12.94) for group 1 and 11.0 ± 1.52 months (95% CI: 8.02-13.97) for group 2 (Log-Rank: 0.584; p = 0.445). The stage and Karnofsky performance status were found to be significant variables on median survival time by univariate analysis. After adjusting for the stage and Karnofsky performance status, the chemotherapy schema was not impressive on median survival time (OR: 0.837; 95% CI: 0.548-1.277; p = 0.409). The progression free survival was 7.0 ± 0.61 months for group I and 6.0 ± 1.56 months for group II (Log-Rank: 0.522; p = 0

    This meta-analysis compared safety profiles (selected drug-related treatment-emergent adverse events [TEAEs]) of first-line pemetrexed plus carboplatin (PCb) area under the concentration-time curve 5 mg/min•mL (PCb5) or 6 mg/min•mL (PCb6), two widely used regimens in clinical practice for advanced non-squamous non-small cell lung cancer. All patients received pemetrexed 500 mg/m 2 every 21 days with either of two carboplatin doses for up to 4-6 cycles. Safety profiles of PCb doses were compared using three statistical analysis methods: frequency table analysis (FTA), generalized linear mixed effect model (GLMM), and the propensity score method. Efficacy outcomes of PCb5 and PCb6 regimens were summarized. A total of 486 patients mainly from the US, Europe, and East Asia were included in the analysis; 22% (n = 105) received PCb5 in one trial and 78% (n = 381) received PCb6 in four trials. The FTA comparison demonstrated that PCb5 vs PCb6 was associated with a statistically significantly lower incidence of TEAEs, including all-grade thrombocytopenia, anemia, fatigue, and vomiting, and grade 3/4 thrombocytopenia. In the GLMM analysis, PCb5 patients were numerically less likely to experience all-grade and grade 3/4 neutropenia, anemia, and thrombocytopenia. The propensity score regression analysis showed PCb5 group patients were significantly less likely than PCb6 group patients to experience all-grade hematologic TEAEs and grade 3/4 thrombocytopenia and anemia. After applying propensity score 1:1 matching, FTA analysis showed that the PCb5 group had significantly less all-grade and grade 3/4 hematologic toxicities. Overall efficacy outcomes, including overall survival, progression-free survival, and response rate, were similar between the two carboplatin doses. Acknowledging the limitations of this meta-analysis of five trials, heterogeneous in patient's characteristics and trial designs, the results show that the PCb5 regimen was generally associated

    Full Text Available Introduction: Lung cancer is the third most frequent neoplastic tumour in Spain, with around 27 000 new cases diagnosed per year; 80-95% of these are non-small-cell cancer (NSCLC, and the majority of cases are diagnosed in advanced stages of the disease, and for this reason it is one of the oncologic conditions with higher mortality rates (21.4% mean survival at 5 years. The main treatment regimens used for first-line treatment of NSCLC are: isplatin/pemetrexed (cis/pem, cisplatin/gemcitabine/ bevacizumab (cis/gem/bev, and carboplatin/paclitaxel/ bevacizumab (carb/pac/bev. The objective of this study was to evaluate the cost-effectiveness ratio of antineoplastic 1st line NSCLC treatment regimens, from the point of view of hospital management. Methodology: A cost-efficacy mathematical model was prepared, based on a decision tree. The efficacy variable was Progression Free Survival, obtained from the PARAMOUNT, AVAIL and SAIL Phase III clinical trials. The study was conducted from the perspective of the hospital management, considering only the direct costs of drug acquisition. A deterministic sensitivity analysis was conducted to confirm the robustness of outcomes. Results: The PFS obtained in clinical trials with cis/pem, cis/ gem/bev and carb/pac/bev was: 6.9, 6.7 and 6.2 months, respectively. Based on our model, the mean cost of treatment per patient for these regimens was: 19 942 €, 15 594 € and 36 095 €, respectively. The incremental cost-effectiveness ratio per month of additional PFS between cis/pem and cis/gem/bev was 19 303 €. Estimating a 30% reduction in acquisition costs for pemetrexed (Alimta®Eli Lilly Nederland B.V., due to the forthcoming launch of generic medications, the cis/pem treatment would become the predominant alternative for 1st line treatment of NSCLC patients, by offering the best health results at a lower cost.

    The long-term effects of tumor necrosis factor (TNF)-blocking therapies on weight-bearing joints in patients with rheumatoid arthritis (RA) have not been fully characterized. The purpose of this study was to assess the radiographic changes of weight-bearing joints in patients with RA during 3-year of TNF-blocking therapies and to identify factors related to the progression of joint damage. Changes in clinical variables and radiological findings in 243 weight-bearing joints (63 hips, 54 knees, 71 ankles, and 55 subtalar joints) in 38 consecutive patients were investigated during three years of treatment with TNF-blocking agents. Multivariate logistic regression analysis was used to identify risk factors for the progression of weight-bearing joint damage. Seventeen (14.5%) of proximal weight-bearing joints (hips and knees) showed apparent radiographic progression during three years of treatment, whereas none of the proximal weight-bearing joints showed radiographic evidence of improvement or repair. In contrast, distal weight-bearing joints (ankle and subtalar joints) displayed radiographic progression and improvement in 20 (15.9%) and 8 (6.3%) joints, respectively. Multivariate logistic analysis for proximal weight-bearing joints identified the baseline Larsen grade (p bearing joints identified disease activity at one year after treatment (p bearing joints. Disease activity after treatment was an independent factor for progression of damage in proximal and distal weight-bearing joints. Early treatment with TNF-blocking agents and tight control of disease activity are necessary to prevent the progression of damage of the weight-bearing joints.

    Full Text Available Abstract Background The RECIST guidelines are commonly used in phase II and III clinical trials. The correct definition of response can be controversial in some situations, as in the case we describe. Case presentation A 43 year-old man with advanced gastric cancer was enrolled in a phase II trial where he was treated with pemetrexed 500 mg/m2 plus oxaliplatin 120 mg/m2 every 3 weeks. At baseline, the target lesions were lymph-nodes, and the non-target lesions were small pulmonary nodules. At first re-evaluation, the target lesions showed partial response and the non-target lesions showed complete response, but new diffuse osteoblastic lesions appeared. The investigator decided to continue treatment until the second re-evaluation. CT scan confirmed the response of the target and non-target lesions, while the osteoblastic lesions did not change. Conclusion The appearance of osteoblastic lesions after an active antitumor treatment, a phenomenon known as flare, can complicate the definition of the best overall response using RECIST criteria. This possibility should be considered by oncologists involved in clinical trials.

    Purpose BIRCH was designed to examine the efficacy of atezolizumab, a humanized anti-programmed death-ligand 1 (PD-L1) monoclonal antibody, in advanced non-small-cell lung cancer (NSCLC) across lines of therapy. Patients were selected on the basis of PD-L1 expression on tumor cells (TC) or tumor-infiltrating immune cells (IC). Patients and Methods Eligible patients had advanced-stage NSCLC, no CNS metastases, and zero to two or more lines of prior chemotherapy. Patients whose tumors expressed PD-L1 using the SP142 immunohistochemistry assay on ≥ 5% of TC or IC (TC2/3 or IC2/3 [TC or IC ≥ 5% PD-L1-expressing cells, respectively]) were enrolled. Atezolizumab 1,200 mg was administered intravenously every 3 weeks. Efficacy-evaluable patients (N = 659) comprised three cohorts: first line (cohort 1; n = 139); second line (cohort 2; n = 268); and third line or higher (cohort 3; n = 252). The primary end point was independent review facility-assessed objective response rate (ORR; Response Evaluation Criteria in Solid Tumors [RECIST] version 1.1). Secondary end points included median duration of response, progression-free survival, and overall survival (OS). Results BIRCH met its primary objective of demonstrating a significant ORR versus historical controls. With a minimum of 12 months of follow-up, the independent review facility-assessed ORR was 18% to 22% for the three cohorts, and 26% to 31% for the TC3 or IC3 subgroup; most responses are ongoing. Responses occurred regardless of EGFR or KRAS mutation status. The median OS from an updated survival analysis (minimum of 20 month follow up) for cohort 1 was 23.5 months (26.9 months for TC3 or IC3 patients); the median OS in cohorts 2 and 3 was 15.5 and 13.2 months, respectively. The safety profile was similar across cohorts and consistent with previous atezolizumab monotherapy trials. Conclusion BIRCH demonstrated responses with atezolizumab monotherapy in patients with PD-L1-selected advanced NSCLC, with good

    What are the effects of experience on subsequent learning? We explored the effects of language-specific word order knowledge on the acquisition of sequential conditional information. Korean and English adults were engaged in a sequence learning task involving three different sets of stimuli: auditory linguistic (nonsense syllables), visual non-linguistic (nonsense shapes), and auditory non-linguistic (pure tones). The forward and backward probabilities between adjacent elements generated two equally probable and orthogonal perceptual parses of the elements, such that any significant preference at test must be due to either general cognitive biases, or prior language-induced biases. We found that language modulated parsing preferences with the linguistic stimuli only. Intriguingly, these preferences are congruent with the dominant word order patterns of each language, as corroborated by corpus analyses, and are driven by probabilistic preferences. Furthermore, although the Korean individuals had received extensive formal explicit training in English and lived in an English-speaking environment, they exhibited statistical learning biases congruent with their native language. Our findings suggest that mechanisms of statistical sequential learning are implicated in language across the lifespan, and experience with language may affect cognitive processes and later learning.

  9. Targeted Therapies for Lung Cancer.

    Stinchcombe, Thomas E

    Targeted therapies have become standard therapies for patients with non-small cell lung cancer (NSCLC). A phase III trial of carboplatin and paclitaxel with and without bevacizumab in patients with advanced NSCLC with non-squamous histology demonstrated a statistically significant improvement in efficacy. In patients with NSCLC with an activating epidermal growth factor receptor (EGFR) mutation (defined as exon 19 deletion and exon 21 L858R point mutation), phase III trials of EGFR tyrosine kinase inhibitors (TKI) compared to platinum-based chemotherapy have demonstrated superior efficacy in the first-line setting. In patients with NSCLC with anaplastic lymphoma kinase (ALK) rearrangements, phase III trials of crizotinib have demonstrated superior efficacy compared to platinum-pemetrexed in the first-line setting and standard chemotherapy in the second-line setting. A second-generation ALK inhibitor, ceritinib, is available for patients who have progressed after or were intolerant of crizotinib. Crizotinib has also demonstrated activity on patients with ROS1 rearrangements, and BRAF inhibitors (dabrafenib, vemurafenib) have demonstrated activity in patients with NSCLC with BRAF V600E mutation. The oncogenic mutations that are susceptible to targeted therapy are mainly found in non-squamous NSCLC. The development of targeted therapy in patients with squamous NSCLC has been more challenging due to the genomic complexity observed in the squamous histology and the low prevalence of EGFR, ALK, and ROS1 molecular alterations. A phase III trial of cisplatin and gemcitabine with and without necitumumab in patients with advanced NSCLC with squamous histology demonstrated a statistically significant improvement in progression-free and overall survival.

    Full Text Available Background: Insulin-like growth factor 1 receptor (IGF-1R regulates cell growth, proliferation and apoptosis. Adenocarcinoma and never-smokers have a higher expression of IGF-1R, which is associated with worse overall survival. Dalotuzumab-MK0646 (D is a humanized monoclonal antibody that targets IGF-1R. Pemetrexed (P has higher activity in non-squamous lung cancer (NSQL. We initiated a randomized phase II trial to test the combination of P and Cisplatin (C +/- D in NSQL.Methods: Eligibility criteria: untreated NSQL stage IIIB or IV, ECOG 0 or 1, measurable disease, adequate renal, hepatic and hematologic function, and no other intercurrent illness. P at 500mg/m2 and C at 75mg/m2 IV were given every 3 weeks. D was given at 10mg/kg IV weekly on days 1, 8 and 15 of every 3-week cycle in the experimental group. The patients had a radiographic assessment after every 2 cycles and were treated for a maximum of 6 cycles if there was a response or stable disease. The primary objective of the study was to compare the clinical response rates of PC vs PC+D. Results: From 1/2009 to 2/2011, the study accrued 26 subjects: 16 male and 10 female, with a median age of 59; 14 were treated with PC and 12 were treated with PC+D. We observed 2 partial responses (PR, 7 stable disease (SD, 3 progressive disease (PD, and 2 were not evaluable (NE in the PC arm. In comparison, for the PC+D arm there were: 3 PR, 4 SD, 4 PD and 1 NE. The hematologic toxicity was similar in both groups. There higher incidence of hyperglycemia the experimental group; 4 cases with grade 3 and 1 case with grade 4. Conclusion: PC+D had a similar response rate compared to PC, with a higher rate of hyperglycemia. Identification of responders using predictive markers would be key to continuing the study of D in NSQL.

    Full Text Available The issue of CEO age and gender vs. concurrent performance is extensively examined, but the association with subsequent performance has limited treatment in the financial literature, and with conflicting findings. In the current study, we examine the association between CEO age and gender, and subsequent company market performance using a more recent set of observations and the standard four-factor model to estimate future cumulative abnormal shareholder returns. We find that subsequent abnormal shareholder returns are marginally significantly higher for female CEOs than for their male counterparts, but no material pattern is observed between CEO age and subsequent abnormal shareholder return performance.

  14. Development and optimization of targeted radionuclide tumor therapy using folate based radiopharmaceuticals

    CERN Document Server

    Reber, Josefine Astrid

    The folate receptor (FR) has been used for a quarter of a century as a tumor-associated target for selective delivery of drugs and imaging agents to cancer cells. While several folic acid radioconjugates have been successfully employed for imaging purposes in (pre)clinical studies, a therapeutic application of folic acid radioconjugates has not yet reached the critical stage which would allow a clinical translation. Due to a substantial expression of the FR in the proximal tubule cells, radiofolates accumulate in the kidneys which are at risk of damage by particle-radiation. To improve this situation, we aimed to develop and evaluate strategies for the performance of FR-targeted radionuclide therapy by decreasing the renal uptake of radiofolates and thereby reducing potential nephrotoxic effects. Two different strategies were investigated. First, the combination of radiofolates with chemotherapeutic agents such as pemetrexed (PMX) and 5-fluorouracil (5-FU) and secondly, an approach based on radioiodinated fol...

    Therapy-resistant and therapy-refractory arterial hypertension differ in prevalence, pathogenesis, prognosis and therapy. In both cases, a structured approach is required, with the exclusion of pseudoresistance and, subsequently, secondary hypertension. Resistant hypertension has been reported to be more responsive to intensified diuretic therapy, whereas refractory hypertension is presumed to require sympathoinhibitory therapy. Once the general measures and the drug-based step-up therapy have been exhausted, interventional procedures are available.

    Purpose: To prospectively assess the survival, patterns of failure, and prognostic factors in a large cohort of patients with malignant pleural mesothelioma who had undergone a novel trimodal therapeutic approach, including lung-sparing surgery, chemotherapy, and subsequent treatment with high doses of intensity modulated radiation therapy (IMRT) to the whole hemithorax. Methods and Materials: The analysis was conducted on the data from 69 patients. Of the 69 patients, 35 underwent extended pleurectomy/decortication (P/D), with resection of the entire pleura, along with portions of the pericardium and diaphragm and 34, partial pleurectomy, defined as partial removal of parietal or visceral pleura for diagnostic purposes, leaving gross tumor behind in all cases. All patients received cisplatin/pemetrexed chemotherapy. Postoperative IMRT was delivered to the entire hemithorax, excluding the intact lung. The IMRT dose was 50 Gy in 25 fractions. Any fluorodeoxyglucose-avid areas or regions of particular concern for residual disease were given a simultaneous boost to 60 Gy. Results: The median follow-up duration was 19 months. No difference was seen in overall survival and locoregional control between the extended P/D group and the partial pleurectomy group. The 2-year overall survival was 65% and 58% in the extended P/D and partial pleurectomy groups, respectively (P=.94). Locoregional control at 2 years was 65% and 64% in the extended P/D and partial pleurectomy groups, respectively (P=.75). The predominant pattern of failure was distant: 19 patients (27.5%) developed distant metastases as the first site of relapse. Gross residual disease after surgery was significantly associated with overall survival (hazard ratio 3.45). One fatal pneumonitis was reported; 14 cases (20%) of grade 2 to 3 pneumonitis were documented. Conclusions: Radical IMRT after lung-sparing surgery and chemotherapy for malignant pleural mesothelioma leads to promising survival results and

    Maintenance therapy (MT) with pemetrexed has been shown to improve overall and progression-free survival of patients with non-squamous non-small cell lung cancer (NSCLC), without impairing patients' health-related quality of life (HRQOL) substantially. Comprehensive data on HRQOL under real-life conditions are necessary to enable informed decision-making. This study aims to (1) assess HRQOL during first-line chemotherapy and subsequent MT and (2) record patients' and physicians' reasons leading to clinical decisions on MT. Patients treated for NSCLC at three Austrian medical centres were included. HRQOL was assessed at every chemotherapy cycle using the EORTC QLQ-C30/+LC13 questionnaire. Semi-structured interviews were conducted before MT initiation and at the time of discontinuation to evaluate patients' and physicians' reasons for treatment decisions. Longitudinal QOL analysis was based on linear mixed models. Sixty-one (73%) out of 84 patients were considered for MT. Thirty-six patients (43%) received MT and 29 (35%) discontinued therapy. Decisions on MT initiation (in 20 cases by the physician vs 4 by the patient) and discontinuation (19 vs 10) were mainly voiced by the physician. Treatment toxicity of first-line chemotherapy was the main reason for rejection of MT in patients with stable disease and was more often indicated by patients than clinicians. HRQOL data were collected from 83 patients at 422 assessment time points and indicated significantly lower symptom severity during MT compared with first-line therapy for nausea and vomiting (p = 0.006), sleep disturbances (p loss (p = 0.043), constipation (p = 0.017) and chest pain (p = 0.022), and a deterioration in emotional functioning (p = 0.023) and cognitive functioning (p = 0.044) during MT. Our results indicate that HRQOL and symptom burden improve between first-line treatment to MT in some respects, although some late toxicity persists. Discrepancies between patients' and physicians

    In a fusion reactor or tritium handling facilities, contamination of concrete by tritium and subsequent release from it to the reactor or experimental rooms is a matter of problem for safety control of tritium and management of operational environment. In order to evaluate these tritium behavior, interaction of tritiated water with concrete or cement should be clarified. In the present study, HTO sorption and subsequent release from cement were studied by combining various experimental methods. From the basic studies on tritium-cement interactions, it has become possible to evaluate tritium uptake by cement or concrete and subsequent tritium release behavior as well as tritium removing methods from them

    In an open, prospective study, we embolised intracranial meningiomas in seven patients, without subsequent surgery. Follow-up over a mean of 20 months included serial neurological examination, MRI and MR spectroscopy. Clinically, embolisation had no adverse effects. Symptomatic patients showed clinical improvement. On MRI marked tumour shrinkage occurred after embolisation in six patients, and was most pronounced during the first 6 months. In a young boy the tumour was unchanged despite complete angiographic devascularisation. Embolisation without subsequent surgery may cause substantial tumour shrinkage and thus be used in selected in patients. However, thorough follow-up is mandatory to ascertain the effects of embolisation. (orig.)

    Based on their different mechanisms of action, non-overlapping side effects and radiosensitising potential, combining the antimetabolites pemetrexed (multitargeted antifolate, MTA) and gemcitabine (2',2'-difluorodeoxycytidine, dFdC) with irradiation (RT) seems promising. This in vitro study, for the first time, presents the triple combination of MTA, dFdC and irradiation using various treatment schedules. The cytotoxicity, radiosensitising potential and cell cycle effect of MTA were investigated in A549 (NSCLC) and CAL-27 (SCCHN) cells. Using simultaneous or sequential exposure schedules, the cytotoxicity and radiosensitising effect of 24 h MTA combined with 1 h or 24 h dFdC were analysed. Including a time interval between MTA exposure and irradiation seemed favourable to MTA immediately preceding or following radiotherapy. MTA induced a significant S phase accumulation that persisted for more than 8 h after drug removal. Among different MTA/dFdC combinations tested, the highest synergistic interaction was produced by 24 h MTA followed by 1 h dFdC. Combined with irradiation, this schedule showed a clear radiosensitising effect. Results from our in vitro model suggest that the sequence 24 h MTA → 1 h dFdC → RT is the most rational design and would, after confirmation in an in vivo setting, possibly provide the greatest benefit in the clinic

    Nine percent of new mothers in the United States who participated in the Listening to Mothers II Postpartum Survey screened positive for meeting the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for posttraumatic stress disorder after childbirth. Women who have had a traumatic birth experience report fewer subsequent children and a longer length of time before their second baby. Childbirth-related posttraumatic stress disorder impacts couples' physical relationship, communication, conflict, emotions, and bonding with their children. The purpose of this study was to describe the meaning of women's experiences of a subsequent childbirth after a previous traumatic birth. Phenomenology was the research design used. An international sample of 35 women participated in this Internet study. Women were asked, "Please describe in as much detail as you can remember your subsequent pregnancy, labor, and delivery following your previous traumatic birth." Colaizzi's phenomenological data analysis approach was used to analyze the stories of the 35 women. Data analysis yielded four themes: (a) riding the turbulent wave of panic during pregnancy; (b) strategizing: attempts to reclaim their body and complete the journey to motherhood; (c) bringing reverence to the birthing process and empowering women; and (d) still elusive: the longed-for healing birth experience. Subsequent childbirth after a previous birth trauma has the potential to either heal or retraumatize women. During pregnancy, women need permission and encouragement to grieve their prior traumatic births to help remove the burden of their invisible pain.

  10. Maintenance therapy in advanced non-small cell lung cancer: current status and future implications.

    Stinchcombe, Thomas E; Socinski, Mark A

    2011-01-01

    Maintenance therapy for patients with advanced non-small cell lung cancer has been an area of intense investigation. Maintenance therapy has been divided into two broad categories: continuation maintenance when the chemotherapy or targeted agent was part of a defined number of cycles of combination therapy and in the absence of disease progression is continued as a single agent or switch maintenance when a third agent is initiated after four cycles of platinum-based double-agent chemotherapy in the absence of disease progression. Two monoclonal antibodies, cetuximab and bevacizumab, are used as continuation maintenance, but the incremental benefit of the maintenance therapy with these agents is undetermined. Phase III trials have not revealed an overall survival benefit for continuation maintenance chemotherapy, and this approach should be considered investigational. Phase III trials have demonstrated an improvement in overall survival with switch maintenance therapy with pemetrexed compared with placebo in patients with nonsquamous histology and erlotinib compared with placebo. Phase III trials have not revealed an improvement in quality of life with maintenance therapy. In the trials of maintenance therapy, 30 to 40% of patients enrolled in the observation or placebo arm did not receive second-line therapy, and among the patients who did receive second-line therapy, there was significant heterogeneity in the therapy. The development of maintenance therapy has raised issues about the role of treatment-free intervals in routine clinical care, trial design issues such as the optimal endpoint, the ethics of a placebo arm, and the implications of maintenance therapy for first-line trials.

    Abstract Periodontitis is a systemic and chronic inflammatory disease associated with multiple physical conditions. Distress and depression are other problems affecting the progression of periodontitis. However, the causal relationship between depression and periodontitis has not been adequately investigated. This aim of this study was to determine the association between periodontitis and the subsequent development of depression. We identified 12,708 patients with newly diagnosed periodontitis from 2000 to 2005 and 50,832 frequency-matched individuals without periodontitis. Both groups were followed until diagnosed with depression, withdrawal from the National Health Insurance program, or the end of 2011. The association between periodontitis and depressio was analyzed using Cox proportional hazard regression models. The incidence density rate of depression was higher in the periodontitis group than in the nonperiodontitis group, with an adjusted hazard ratio of 1.73 (95% confidence interval 1.58–1.89) when adjusting for sex, age, and comorbidity. Cox models revealed that periodontitis was an independent risk factor for depression in patients, except for comorbidities of diabetes mellitus (DM), alcohol abuse, and cancer. Periodontitis may increase the risk of subsequent depression and was suggested an independent risk factor regardless of sex, age, and most comorbidities. However, DM, alcohol abuse, and cancer may prevent the development of subsequent depression because of DM treatment, the paradoxical effect of alcohol, and emotional distress to cancer, respectively. Prospective studies on the relationship between periodontitis and depression are warranted. PMID:26705230

    There has been continued interest in the extent to which women have positive and negative reactions to abortion. To document emotional reactions to abortion, and to examine the links between reactions to abortion and subsequent mental health outcomes. Data were gathered on the pregnancy and mental health history of a birth cohort of over 500 women studied to the age of 30. Abortion was associated with high rates of both positive and negative emotional reactions; however, nearly 90% of respondents believed that the abortion was the right decision. Analyses showed that the number of negative responses to the abortion was associated with increased levels of subsequent mental health disorders (Pabortion and reporting negative reactions had rates of mental health disorders that were approximately 1.4-1.8 times higher than those not having an abortion. Abortion was associated with both positive and negative emotional reactions. The extent of negative emotional reactions appeared to modify the links between abortion and subsequent mental health problems.

    Twenty-seven children with acute leukemia were studied in order to detect the subsequent neurologic complications due to chemotherapy and radiation therapy. Twenty-four patients with ALL received central nervous system prophylaxis including cranial irradiation. The methods of evaluation consisted of electroencephalogram (EEG), computed tomography of the head (CT scan), soft neurological sign, intelligence quotient (IQ) and Bender Gestalt test. The patients with relapse showed severe abnormalities in various kinds of examinations. Younger children at diagnosis were associated with a higher abnormality rate of soft neurological signs and Bender Gestalt test. Factors which were found to be closely associated with a lower IQ score included younger children at diagnosis and longer duration of remission time. These results indicate the need for caution for the dosage of cranial irradiation for younger patients in CNS prophylaxis, and improvement of a lower IQ score in long-term survivors requires further investigation as to the appropriate intellectual environment for their development after remission.

    In a fusion reactor or tritium-handling facilities, contamination of concrete by tritium and subsequent release from it to the reator or experimental room is a matter of problem for safe control of tritium and management of operational environment. In order to evaluate this tritium behavior, interaction of tritiated water with concrete or cement should be clarified. In the present study, HTO sorption and subsequent release from cement were experimentally studied.(1)Sorption experiments were conducted using columns packed with cement particles of different sizes. From the analysis of the breakthrough curve, tritium diffusivity in macropores and microparticles were evaluated.(2)From the short-term tritium release experiments, effective desorption rate constants were evaluated and the effects of temperature and moisture were studied.(3)In the long-term tritium release experiments to 6000h, the tritium release mechanism was found to be composed of three kinds of water: initially from capillary water, and in the second stage from gel water and from the water in the cement crystal.(4)Tritium release behavior by heat treatment to 800 C was studied. A high temperature above 600 C was required for the tritium trapped in the crystal water to be released. (orig.)

    Cross-sectional studies demonstrate that exposure to bullying in the workplace is positively correlated with self-reported health problems. However, these studies do not provide a basis to draw conclusions on the extent to which bullying leads to increased health problems or whether health problems increase the risk of being bullied. To provide better indications of a causal relationship, knowledge from prospective studies on the association between bullying in the workplace and health outcomes is therefore summarised. We conducted a systematic literature review of original articles from central literature databases on longitudinal associations between bullying in the workplace and health. Average associations between bullying and health outcomes are calculated using meta-analysis. A consistent finding across the studies is that exposure to bullying is significantly positively related to mental health problems (OR =1.68; 95% KI 1.35-2.09) and somatic symptoms (OR = 1.77; 95% KI 1.41-2.22) over time. Mental health problems are also associated with subsequent exposure to bullying (OR = 1.74; 95% KI 1.44-2.12). Bullying is positively related to mental health problems and somatic symptoms. The association between mental health problems and subsequent bullying indicates a self-reinforcing process between mental health and bullying. The methodological quality of the studies that were conducted is relatively sound. However, based on the existing knowledge base there are no grounds for conclusions regarding an unambiguous causal relationship between bullying and health.

    Human activity recognition is one of the most important research topics in the era of Internet of Things. To separate different activities given sensory data, we utilize a Minimal Distinguishing Subsequence (MDS) mining approach to efficiently find distinguishing patterns among different activities. We first transform the sensory data into a series of sensor triggering events and operate the MDS mining procedure afterwards. The gap constraints are also considered in the MDS mining. Given the multi-class nature of most activity recognition tasks, we modify the MDS mining approach from a binary case to a multi-class one to fit the need for multiple activity recognition. We also study how to select the best parameter set including the minimal and the maximal support thresholds in finding the MDSs for effective activity recognition. Overall, the prediction accuracy is 86.59% on the van Kasteren dataset which consists of four different activities for recognition.

    Behavioural studies over half a century indicate that making categorical choices alters beliefs about the state of the world. People seem biased to confirm previous choices, and to suppress contradicting information. These choice-dependent biases imply a fundamental bound of human rationality. However, it remains unclear whether these effects extend to lower level decisions, and only little is known about the computational mechanisms underlying them. Building on the framework of sequential-sampling models of decision-making, we developed novel psychophysical protocols that enable us to dissect quantitatively how choices affect the way decision-makers accumulate additional noisy evidence. We find robust choice-induced biases in the accumulation of abstract numerical (experiment 1) and low-level perceptual (experiment 2) evidence. These biases deteriorate estimations of the mean value of the numerical sequence (experiment 1) and reduce the likelihood to revise decisions (experiment 2). Computational modelling reveals that choices trigger a reduction of sensitivity to subsequent evidence via multiplicative gain modulation, rather than shifting the decision variable towards the chosen alternative in an additive fashion. Our results thus show that categorical choices alter the evidence accumulation mechanism itself, rather than just its outcome, rendering the decision-maker less sensitive to new information. © 2015 The Author(s) Published by the Royal Society.

  19. Mental imagery affects subsequent automatic defense responses

    Full Text Available Automatic defense responses promote survival and appropriate action under threat. They have also been associated with the development of threat-related psychiatric syndromes. Targeting such automatic responses during threat may be useful in populations with frequent threat exposure. Here, two experiments explored whether mental imagery as a pre-trauma manipulation could influence fear bradycardia (a core characteristic of freezing during subsequent analogue trauma (affective picture viewing. Image-based interventions have proven successful in the treatment of threat-related disorders, and are easily applicable. In Experiment 1 43 healthy participants were randomly assigned to an imagery script condition. Participants executed a passive viewing task with blocks of neutral, pleasant and unpleasant pictures after listening to an auditory script that was either related (with a positive or a negative outcome or unrelated to the unpleasant pictures from the passive viewing task. Heart rate was assessed during script listening and during passive viewing. Imagining negative related scripts resulted in greater bradycardia (neutral-unpleasant contrast than imagining positive scripts, especially unrelated. This effect was replicated in Experiment 2 (N = 51, again in the neutral-unpleasant contrast. An extra no-script condition showed that bradycardia was not induced by the negative related script, but rather that a positive script attenuated bradycardia. These preliminary results might indicate reduced vigilance after unrelated positive events. Future research should replicate these findings using a larger sample. Either way, the findings show that highly automatic defense behavior can be influenced by relatively simple mental imagery manipulations.

    Based on CT findings one year after shunting, ventricular dialtion was classified into five degrees for examining prognosis of communicating hydrocephalus subsequent to purulent meningitis. Factors causing and aggravating hydrocephalus were also examined. Patients with hydrocephalus tended to have spasms frequently as the first symptom within one month after birth when there were few characteristic findings. Spasm and disturbance of consciousness occurred frequently during the first week of the occurrence of disease. Large numbers of cells in the spinal fluid and high volume of spinal cord protein were persistent in patients aged one month or less. Chloride transport decreased in patients aged two months or more. The occurrence of syndrome of the pyramidal tract, eye symptoms, movement of head to the left and right, and involuntary movement suggested serious conditions of the disease. Disturbance of movement could be relieved by giving adequate antibiotics as soon as meningitis was discovered within one month after birth and by giving chloramphenicol when symptoms suggesting the development of serious conditions occurred. However, mental retardation and epilepsy could not be prevented. (Namekawa, K.)

    We present a new algorithm for subsequence matching in grammar compressed strings. Given a grammar of size n compressing a string of size N and a pattern string of size m over an alphabet of size \\(\\sigma \\), our algorithm uses \\(O(n+\\frac{n\\sigma }{w})\\) space and \\(O(n+\\frac{n\\sigma }{w}+m\\log N\\log...... w\\cdot occ)\\) or \\(O(n+\\frac{n\\sigma }{w}\\log w+m\\log N\\cdot occ)\\) time. Here w is the word size and occ is the number of minimal occurrences of the pattern. Our algorithm uses less space than previous algorithms and is also faster for \\(occ=o(\\frac{n}{\\log N})\\) occurrences. The algorithm uses...... a new data structure that allows us to efficiently find the next occurrence of a given character after a given position in a compressed string. This data structure in turn is based on a new data structure for the tree color problem, where the node colors are packed in bit strings....

  2. Second-line combination therapies in nonsmall cell lung cancer without known driver mutations

    2015-12-01

    Full Text Available In advanced nonsmall cell lung cancer (NSCLC patients, platinum-based combination chemotherapy is standard treatment in the first-line setting; however, the large majority of patients ultimately progress. For more than a decade, single-agent therapy with docetaxel, pemetrexed or erlotinib has been the standard of care after failure with platinum salts, showing some benefit over best supportive care. Nonetheless, prognosis remains poor and new second-line strategies are urgently needed. Combinations of cytotoxic agents, including rechallenge with platinum salts, do not offer clear benefit over single-agent therapy for the majority of patients. In patients without a known tumoural oncogenic driver mutation, regimens based on combinations of targeted agents have shown promising results; however, a clear role in therapeutic management is yet to be established. Some success has been reported in recent research combining a cytotoxic agent with targeted therapies. In this review, we summarise published data for the various strategies evaluated over the past decade in second-line treatment of NSCLC patients without a known driver mutation. We focus on combination treatments and consider future perspectives, including the need to identify predictive markers to support personalised therapeutic strategies.

    Wheezing in infancy has been associated with subsequent asthma, but whether cough similarly influences asthma risk has been little studied. We sought to determine whether prolonged cough and cough without cold in the first year of life are associated with childhood asthma. Participants in the Infant Immune Study, a non-selected birth cohort, were surveyed 7 times in the first 9 months of life regarding the presence of wheeze and cough. Cough for more than 28 days was defined as prolonged. Parents were asked at 1 year if the child ever coughed without a cold. Asthma was defined as parental report of physician diagnosis of asthma, with symptoms or medication use between 2 and 9 years. Logistic regression was used to assess adjusted odds for asthma associated with cough characteristics. A total of 24% (97) of children experienced prolonged cough and 23% (95) cough without cold in the first 9 months, respectively. Prolonged cough was associated with increased risk of asthma relative to brief cough (OR 3.57, CI: 1.88, 6.76), with the risk being particularly high among children of asthmatic mothers. Cough without cold (OR 3.13, 95% CI: 1.76, 5.57) was also independently associated with risk of childhood asthma. Both relations persisted after adjustment for wheeze and total IgE at age 1. Prolonged cough in infancy and cough without cold are associated with childhood asthma, independent of infant wheeze. These findings suggest that characteristics of cough in infancy are early markers of asthma susceptibility, particularly among children with maternal asthma. © 2015 John Wiley & Sons Ltd.

    Full Text Available Ewing’s sarcoma is a primary bone cancer that mainly affects the long bones. This malignancy is particularly common in pediatric patients. Primary cranial involvement accounts for 1% of cases, with occipital involvement considered extremely rare. In this case study, primary occipital Ewing’s sarcoma with a posterior fossa mass and subsequent relapse resulting in spinal seeding is reported. A 3-year-old patient presented with a 1-year history of left-sided headaches, localized over the occipital bone with progressive torticollis. Computed tomography (CT imaging showed a mass in the left posterior fossa compressing the brainstem. The patient then underwent surgical excision followed by adjuvant chemoradiation therapy. Two years later, the patient presented with severe lower back pain and urinary incontinence. Whole-spine magnetic resonance imaging (MRI showed cerebrospinal fluid (CSF seeding from the L5 to the S4 vertebrae. Primary cranial Ewing’s sarcoma is considered in the differential diagnosis of children with extra-axial posterior fossa mass associated with destructive permeative bone lesions. Although primary cranial Ewing’s sarcoma typically has good prognosis, our patient developed metastasis in the lower spine. Therefore, with CNS Ewing’s sarcoma, screening of the entire neural axis should be taken into consideration for early detection of CSF seeding metastasis in order to decrease the associated morbidity and mortality.

    Control of non-small-cell lung cancer (NSCLC) with brain metastasis is clinically challenging. This study retrospectively evaluated the efficacy of different adjuvant therapies for 776 cases of advanced NSCLCs with brain metastasis who treated with chemotherapy, chemotherapy plus bevacizumab, tyrosine kinase inhibitor (TKI) alone, or supportive care. The median progression-free survival (mPFS) and median overall survival (mOS) of patients treated with chemotherapy plus bevacizumab were 8.5 and 10.5 months, respectively, which were better than those of patients treated with other three therapies(P chemotherapy plus bevacizumab but was significantly better than that of other therapies. Moreover, for patients with EGFR wild-type NSCLC, the mPFS and mOS after chemotherapy plus bevacizumab were greater than those with other two therapies (P Chemotherapy plus bevacizumab was more effective for NSCLC patients with brain metastasis. Further studies will investigate the benefit of TKI alone for patients with EGFR-mutated. For patients with EGFR wild-type, chemotherapy plus bevacizumab did improve PFS and OS. Furthermore, regimens including pemetrexed led to a greater RR.

    This phase III study investigated whether continuation maintenance with gemcitabine or switch maintenance with erlotinib improves clinical outcome compared with observation in patients with advanced non-small-cell lung cancer (NSCLC) whose disease was controlled after cisplatin-gemcitabine induction chemotherapy. Four hundred sixty-four patients with stage IIIB/IV NSCLC without tumor progression after four cycles of cisplatin-gemcitabine were randomly assigned to observation or to gemcitabine (1,250 mg/m(2) days 1 and 8 of a 3-week cycle) or daily erlotinib (150 mg/day) study arms. On disease progression, patients in all three arms received pemetrexed (500 mg/m(2) once every 21 days) as predefined second-line therapy. The primary end point was progression-free survival (PFS). PFS was significantly prolonged by gemcitabine (median, 3.8 v 1.9 months; hazard ratio [HR], 0.56; 95% CI, 0.44 to 0.72; log-rank P benefit was consistent across all clinical subgroups. Both maintenance strategies resulted in a nonsignificant improvement in overall survival (OS); patients who received second-line pemetrexed or with a performance status of 0 appeared to derive greater benefit. Exploratory analysis showed that magnitude of response to induction chemotherapy may affect the OS benefit as a result of gemcitabine maintenance. Maintenance gemcitabine and erlotinib were well tolerated with no unexpected adverse events. Gemcitabine continuation maintenance or erlotinib switch maintenance significantly reduces disease progression in patients with advanced NSCLC treated with cisplatin-gemcitabine as first-line chemotherapy. Response to induction chemotherapy may affect OS only for continuation maintenance.

    Justification for the Use of Statins in Primary Prevention: An Intervention Trial Using Rosuvastatin (JUPITER) reported reduced cardiovascular and all-cause mortality with statin treatment in patients with elevated C-reactive protein (CRP) and average cholesterol levels who were not eligible for lipid-lowering treatment on the basis of existing guidelines. The aim of this study was to determine the prevalence of eligibility and mortality in a general population sample on the basis of eligibility for statin treatment using the JUPITER criteria. The study group consisted of 30,229 participants in the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort, an observational study of US African American and white participants aged > or =45 years, enrolled in their homes from 2003 to 2007 and followed biannually by telephone. Among 11,339 participants age eligible for JUPITER and without vascular diagnoses or using lipid-lowering treatment, 21% (n = 2,342) met JUPITER entry criteria. Compared with JUPITER participants, they had similar low-density lipoprotein cholesterol and CRP levels, were more often women, were more often black, had metabolic syndrome, and used aspirin for cardioprotection. Over 3.5 years of follow-up, the mortality rate in REGARDS participants eligible for JUPITER was 1.17 per 100 patient-years (95% confidence interval 0.94 to 1.42). Compared with those otherwise JUPITER eligible who had CRP levels or =2 mg/L had a multivariate-adjusted relative risk of 1.5 (95% confidence interval 1.1 to 2.2) for total mortality. In conclusion, 21% not otherwise eligible would be newly eligible for lipid lowering treatment on the basis of JUPITER trial eligibility.

    Full Text Available Collateral in terms of subsequently acquired assets namely subsequently acquired credit might be charged with fiduciary security. This collateral is not considered ideal regarding the high risk a bank must take. To minimize the risks, the bank analyzes the credit thoroughly, impose fiduciary security officials perfectly and performs monitoring of credits regularly to avoid misconduct committed by the debtor. If a default occurs, the bank will take over the assets. Nevertheless, the problems of execution on the subsequently acquired credits might arise due to debtor’s default and bad debts to the third party. Consequently, subsequently acquired assets as collateral provides as additional collateral. Keywords: bank, subsequently acquired objects, fiduciary, security, loans.

    Fast neutron therapy began as long ago as 1938 and subsequently proton, alpha particle, heavy ion, pion and neutron capture therapy have been used. To date it is estimated that in excess of 45000 people have undergone some form of hadron therapy. In the future it is expected that fast neutron therapy will be used for selected tumour types for which neutron are known to show improved cure rates. The future trends in charged particle therapy will be driven by increasing commercialization. The future of neutron capture therapy will depend on current clinical trials with epithermal neutron beams and the development of new tumour-seeking drugs

    2010-11-01

    Lung cancer is the most common cancer worldwide with non-small cell lung cancer (NSCLC), including squamous carcinoma, adenocarcinoma and large cell carcinoma, accounting for about 85% of all lung cancer types with most of the patients presenting with advanced disease at the time of diagnosis. In this setting first-line platinum-based chemotherapy for no more than 4-6 cycles are recommended. After these cycles of treatment, non-progressing patients enter in the so called "watch and wait" period in which no further therapy is administered until there is disease progression. In order to improve the advanced NSCLC outcomes, the efficacy of further treatment in the "watch and wait" period was investigated. This is the "maintenance therapy". Recently, the results coming from randomized phase III trials investigating two new agents, pemetrexed and erlotinib, in this setting led to their registration for maintenance therapy. Here, we report and discuss these results. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Healthy children are often required to repeatedly undergo painful medical procedures (eg, immunizations). Although memory is often implicated in children's reactions to future pain, there is a dearth of research directly examining the relationship between the 2. The current study investigated the influence of children's memories for a novel pain stimulus on their subsequent pain experience. One hundred ten healthy children (60 boys) between the ages of 8 and 12 years completed a laboratory pain task and provided pain ratings. Two weeks later, children provided pain ratings based on their memories as well as their expectancies about future pain. One month following the initial laboratory visit, children again completed the pain task and provided pain ratings. Results showed that children's memory of pain intensity was a better predictor of subsequent pain reporting than their actual initial reporting of pain intensity, and mediated the relationship between initial and subsequent pain reporting. Children who had negatively estimated pain memories developed expectations of greater pain prior to a subsequent pain experience and showed greater increases in pain ratings over time than children who had accurate or positively estimated pain memories. These findings highlight the influence of pain memories on healthy children's expectations of future pain and subsequent pain experiences and extend predictive models of subsequent pain reporting.

    Background Previous work has suggested significant associations between various psychological symptoms (e.g. depression, anxiety, anger, alcohol abuse) and hypertension. However, the presence and extent of associations between common mental disorders and subsequent adult onset of hypertension remains unclear. Further, there is little data available on how such associations vary by gender or over life course. Methods Data from the World Mental Health Surveys (comprising 19 countries, and 52,095 adults) were used. Survival analyses estimated associations between first onset of common mental disorders and subsequent onset of hypertension, with and without psychiatric comorbidity adjustment. Variations in the strength of associations by gender and by life course stage of onset of both the mental disorder and hypertension were investigated. Results After psychiatric comorbidity adjustment, depression, panic disorder, social phobia, specific phobia, binge eating disorder, bulimia nervosa, alcohol abuse, and drug abuse were significantly associated with subsequent diagnosis of hypertension (with ORs ranging from 1.1 to 1.6). Number of lifetime mental disorders was associated with subsequent hypertension in a dose-response fashion. For social phobia and alcohol abuse, associations with hypertension were stronger for males than females. For panic disorder, the association with hypertension was particularly apparent in earlier onset hypertension. Conclusions Depression, anxiety, impulsive eating disorders, and substance use disorders disorders were significantly associated with the subsequent diagnosis of hypertension. These data underscore the importance of early detection of mental disorders, and of physical health monitoring in people with these conditions.. PMID:24342112

    2013-01-01

    This study sought to increase understanding of women's thoughts and feelings about decision making and the experience of subsequent pregnancy following stillbirth (intrauterine death after 24 weeks' gestation). Eleven women were interviewed, 8 of whom were pregnant at the time of the interview. Modified grounded theory was used to guide the research methodology and to analyze the data. A model was developed to illustrate women's experiences of decision making in relation to subsequent pregnancy and of subsequent pregnancy itself. The results of the current study have significant implications for women who have experienced stillbirth and the health professionals who work with them. Based on the model, women may find it helpful to discuss their beliefs in relation to healing and health professionals to provide support with this in mind. Women and their partners may also benefit from explanations and support about the potentially conflicting emotions they may experience during this time. © 2013 by the American College of Nurse-Midwives.

    The testing effect is the finding that prior retrieval of information from memory will result in better subsequent memory for that material. One explanation for these effects is that initial free recall testing increases the recollective details for tested information, which then becomes more available during a subsequent test phase. In three experiments we explored this hypothesis using a source-monitoring test phase after the initial free recall tests. We discovered that memory is differentially enhanced for certain recollective details depending on the nature of the free recall task. Thus further research needs to be conducted to specify how different kinds of memorial details are enhanced by free recall testing.

    The description of passive components and systems published by the IAEA in its TECDOC-626 was developed in the course of a Technical Committee Meeting held in Sweden and two subsequent Consultants Meetings held in Vienna. This description is reviewed and discussed in terms of the philosophies behind it, alternatives considered, problems encountered, and conclusions drawn. Also discussed is an Appendix to the TECDOC, which illustrates the spectrum of possibilities from passive to active by describing four typical categories of passivity. Subsequent thoughts on passive safety include a discussion of its advantages and disadvantages, concluding with a summary of current views and problems with it. (author). 8 refs.

  12. A Novel Image Encryption Algorithm Based on DNA Subsequence Operation

    Directory of Open Access Journals (Sweden)

    Qiang Zhang

    2012-01-01

    Full Text Available We present a novel image encryption algorithm based on DNA subsequence operation. Different from the traditional DNA encryption methods, our algorithm does not use complex biological operation but just uses the idea of DNA subsequence operations (such as elongation operation, truncation operation, deletion operation, etc. combining with the logistic chaotic map to scramble the location and the value of pixel points from the image. The experimental results and security analysis show that the proposed algorithm is easy to be implemented, can get good encryption effect, has a wide secret key's space, strong sensitivity to secret key, and has the abilities of resisting exhaustive attack and statistic attack.

  14. Nerve agent intoxication: Recent neuropathophysiological findings and subsequent impact on medical management prospects

    International Nuclear Information System (INIS)

    Collombet, Jean-Marc

    2011-01-01

    This manuscript provides a survey of research findings catered to the development of effective countermeasures against nerve agent poisoning over the past decade. New neuropathophysiological distinctive features as regards organophosphate (OP) intoxication are presented. Such leading neuropathophysiological features include recent data on nerve agent-induced neuropathology, related peripheral or central nervous system inflammation and subsequent angiogenesis process. Hence, leading countermeasures against OP exposure are down-listed in terms of pre-treatment, protection or decontamination and emergency treatments. The final chapter focuses on the description of the self-repair attempt encountered in lesioned rodent brains, up to 3 months after soman poisoning. Indeed, an increased proliferation of neuronal progenitors was recently observed in injured brains of mice subjected to soman exposure. Subsequently, the latter experienced a neuronal regeneration in damaged brain regions such as the hippocampus and amygdala. The positive effect of a cytokine treatment on the neuronal regeneration and subsequent cognitive behavioral recovery are also discussed in this review. For the first time, brain cell therapy and neuronal regeneration are considered as a valuable contribution towards delayed treatment against OP intoxication. To date, efficient delayed treatment was lacking in the therapeutic resources administered to patients contaminated by nerve agents. - Highlights: → This review focuses on neuropathophysiology following nerve agent poisoning in mice. → Extensive data on long-term neuropathology and related inflammation are provided here. → Delayed self-repair attempts encountered in lesioned rodent brains are also described. → Cell therapy is considered as a valuable treatment against nerve agent intoxication.

  15. Early pneumothorax as a feature of response to crizotinib therapy in a patient with ALK rearranged lung adenocarcinoma

    Single arm phase 1 and 2 studies on Crizotinib in ALK-positive patients so far have shown rapid and durable responses. Spontaneous pneumothoraces as a result of response to anti-cancer therapy are rare in oncology but have been documented in a number of tumour types including lung cancer. This includes cytotoxic chemotherapy as well as molecular targeted agents such as gefitinib and Bevacizumab. These often require chest drain insertion or surgical intervention with associated morbidity and mortality. They have also been associated with response to treatment. This is the first report we are aware of documenting pneumothorax as response to crizotinib therapy. A 48-year-old Caucasian male presented with a Stage IV, TTF1 positive, EGFR wild-type adenocarcinoma of the lung. He received first line chemotherapy with three cycles of cisplatin-pemetrexed chemotherapy with a differential response, and then second-line erlotinib for two months before further radiological evidence of disease progression. Further analysis of his diagnostic specimen identified an ALK rearrangement by fluorescence in situ hybridization (FISH). He was commenced on crizotinib therapy 250 mg orally twice daily. At his 4-week assessment he had a chest radiograph that identified a large left-sided pneumothorax with disease response evident on the right. Chest CT confirmed a 50% left-sided pneumothorax on a background of overall disease response. A chest tube was inserted with complete resolution of the pneumothorax that did not recur following its removal. Our case demonstrates this potential complication of crizotinib therapy and we therefore recommend that pneumothorax be considered in patients on crizotinib presenting with high lung metastatic burden and with worsening dyspnoea

    Individuals who sustain their first concussion during childhood may be at greater risk of sustaining multiple concussions throughout their lifetime because of a longer window of vulnerability. This article aims to estimate the association between age at first concussion and number of subsequent concussions. A total of 23,582 collegiate athletes from 26 universities and military cadets from three military academies completed a concussion history questionnaire (65% males, age 19.9 ± 1.4 years). Participants self-reported concussions and age at time of each injury. Participants with a history of concussion (n = 3,647, 15.5%) were categorized as having sustained their first concussion during childhood (less than ten years old) or adolescence (≥10 and ≤18 years old). Poisson regression was used to model age group (childhood, adolescence) predicting the number of subsequent concussions (0, 1, 2+). A second Poisson regression was developed to determine whether age at first concussion predicted the number of subsequent concussions. Participants self-reporting their first concussion during childhood had an increased risk of subsequent concussions (rate ratio = 2.19, 95% confidence interval: 1.82, 2.64) compared with participants self-reporting their first concussion during adolescence. For every one-year increase in age at first concussion, we observed a 16% reduction in the risk of subsequent concussion (rate ratio = 0.84, 95% confidence interval: 0.82, 0.86). Individuals self-reporting a concussion at a young age sustained a higher number of concussions before age 18. Concussion prevention, recognition, and reporting strategies are of particular need at the youth level. Copyright © 2018 Elsevier Inc. All rights reserved.

    Jastreboff, P J

    2007-01-01

    Tinnitus retraining therapy (TRT) is a specific clinical method based on the neurophysiological model of tinnitus described by Jastreboff (Jastreboff, P.J. (1990). Neurosci. Res., 8: 221-254). The method is aimed at habituation of reactions evoked by tinnitus, and subsequently habituation of the tinnitus perception. Several other methods have been suggested for habituation of tinnitus, but in TRT two components that strictly follow the principles of the neurophysiological model of tinnitus are implemented and necessary: (1) counseling, aimed at reclassification of tinnitus to a category of a neutral signals and (2) sound therapy, aimed at weakening tinnitus-related neuronal activity as suggested by Jastreboff and Hazell (Jastreboff, P.J. and Hazell, J.W.P. (2004). Cambridge University Press, Cambridge). This chapter outlines the theoretical basis of TRT as well as comments on the clinical outcome of the use of TRT for different kinds of tinnitus.

  13. Histopathologic changes in fallopian tubes subsequent to sterilization procedures.

    Science.gov (United States)

    Stock, R J

    1983-01-01

    Longitudinal serial and serial step sections of fallopian tubes from more than 100 patients, subsequent to tubal sterilization procedures, were examined. Thirteen of these patients had pregnancies following their sterilizations. The histologic findings at the previous surgical sites were compatible with what would be expected for a normal healing process. Evidence for a unique tubal epithelial process, as suggested by the terms "endosalpingiosis" or "recanalization," was lacking. Likewise, the author found no evidence of tuboperitoneal fistula formation and/or the subsequent occurrence of pregnancy secondary to localized endometriosis. The histologic notations of proximal luminal dilatation, plical attenuation, chronic inflammatory infiltrates with pseudopolyp formation, and the findings of plical thickening in the distal segment of remaining tube after an interruption type of procedure seem to be associated with the length of time from the sterilization procedure. These may be factors related to the apparent reduced success rate, with time, of microsurgical reanastomotic procedures.

    To quantify the incidence of and identify the risk factors for subsequent shoulder procedures after isolated SLAP repair. New York's Statewide Planning and Research Cooperative System database was searched between 2003 and 2014 to identify individuals with the sole diagnosis of a SLAP lesion who underwent isolated arthroscopic SLAP repair. Patients were longitudinally followed up for a minimum of 3 years to analyze for subsequent ipsilateral shoulder procedures. Between 2003 and 2014, 2,524 patients met our inclusion criteria. After 3 to 11 years of follow-up, 10.1% of patients (254 of 2,524) underwent repeat surgical intervention on the same shoulder as the initial SLAP repair. The mean time to repeat shoulder surgery was 2.3 ± 2.1 years. Subsequent procedures included subacromial decompression (35%), debridement (26.7%). repeat SLAP repair (19.7%), and biceps tenodesis or tenotomy (13.0%). After isolated SLAP repair, patients aged 20 years or younger were more likely to undergo arthroscopic Bankart repair (odds ratio [OR], 2.91; 95% confidence interval [CI], 1.36-6.21; P = .005), whereas age older than 30 years was an independent risk factor for subsequent acromioplasty (OR, 2.3; 95% CI, 1.4-3.7; P surgery after isolated SLAP repair, often related to an additional diagnosis, suggesting that clinicians should consider other potential causes of shoulder pain when considering surgery for patients with SLAP lesions. In addition, the number of isolated SLAP repairs performed has decreased over time, and management of failed SLAP repair has shifted toward biceps tenodesis or tenotomy over revision SLAP repair in more recent years.

    2011-01-01

    Quartz crystal microbalance with dissipation (QCM-D) technique was employed for protein adsorption and subsequent fibroblast adhesion on hydroxyapatite (HAp) nanocrystals. The pre-adsorption of three proteins (albumin (BSA) or fibronectin (Fn) or collagen (Col)) and subsequent adsorption of fetal bovine serum (FBS), and the adhesion of fibroblasts on the surface were in situ monitored, and evaluated with the frequency shift (Δf) and dissipation energy shift (ΔD), and the viscoelastic change as ΔD-Δf plot. The Col adsorption showed larger Δf and ΔD values compared with BSA or Fn adsorption, and the subsequent FBS adsorption depended on the pre-adsorbed proteins. The ΔD-Δf plot of the cell adhesion also showed the different behaviour on the surfaces, indicating the process affected by cell-protein interactions. The confocal laser scanning microscope images of adherent cells showed the different morphology and pseudopod on the surfaces. The cells adhered on the surfaces modified with Fn and Col had the uniaxially expanded shape with fibrous pseudopods, while those modified with BSA had round shape. The different cell-protein interaction would cause the arrangement of extracellular matrix and cytoskeleton changes at the interfaces.

    2013-07-02

    The objective was to examine the effect of consuming breakfast on subsequent energy intake. Participants who habitually ate breakfast and those who skipped breakfast were recruited for two studies. Using a randomized crossover design, the first study examined the effect of having participants consume either (a) no breakfast, (b) a high carbohydrate breakfast (335 kcals), or (c) a high fiber breakfast (360 kcals) on three occasions and measured ad libitum intake at lunch. The second study again used a randomized crossover design but with a larger, normal carbohydrate breakfast consumed ad libtum. Intake averaged 624 kcals and subsequent food intake was measured throughout the day. Participants ate only foods served from the Cornell Human Metabolic Research Unit where all foods were weighed before and after consumption. In the first study, neither eating breakfast nor the kind of breakfast consumed had an effect on the amount consumed at lunch despite a reduction in hunger ratings. In the second study, intake at lunch as well as hunger ratings were significantly increased after skipping breakfast (by 144 kcal), leaving a net caloric deficit of 408 kcal by the end of the day. These data are consistent with published literature demonstrating that skipping a meal does not result in accurate energy compensation at subsequent meals and suggests that skipping breakfast may be an effective means to reduce daily energy intake in some adults.

    Previous studies in various medical specialties have shown that fewer than 50% of abstracts presented at meetings are subsequently published. The purpose of the present study was to determine the publication rate of abstracts presented at the annual meetings of the American Association of Oral and Maxillofacial Surgeons. The titles and authors of the abstracts from all oral abstract session presentations and posters by American contributors were collected from the Final Programs of the American Association of Oral and Maxillofacial Surgeons annual meetings for 2006 to 2009. A PubMed search for published articles through December 2010 was then performed using the authors' names, abstract titles, and key words. A total of 311 abstract presentations were done at the 4 annual meetings. Of these, only 85 (24%) were subsequently published. No difference was found between abstracts from oral or poster presentations. Most of the articles were published in the Journal of Oral and Maxillofacial Surgery. Because of deficiencies that can occur in abstracts and the need to disseminate the information they contain, it is important to take the appropriate measures to ensure that full articles are subsequently published.

    Quartz crystal microbalance with dissipation (QCM-D) technique was employed for protein adsorption and subsequent fibroblast adhesion on hydroxyapatite (HAp) nanocrystals. The pre-adsorption of three proteins (albumin (BSA) or fibronectin (Fn) or collagen (Col)) and subsequent adsorption of fetal bovine serum (FBS), and the adhesion of fibroblasts on the surface were in situ monitored, and evaluated with the frequency shift ({Delta}f) and dissipation energy shift ({Delta}D), and the viscoelastic change as {Delta}D-{Delta}f plot. The Col adsorption showed larger {Delta}f and {Delta}D values compared with BSA or Fn adsorption, and the subsequent FBS adsorption depended on the pre-adsorbed proteins. The {Delta}D-{Delta}f plot of the cell adhesion also showed the different behaviour on the surfaces, indicating the process affected by cell-protein interactions. The confocal laser scanning microscope images of adherent cells showed the different morphology and pseudopod on the surfaces. The cells adhered on the surfaces modified with Fn and Col had the uniaxially expanded shape with fibrous pseudopods, while those modified with BSA had round shape. The different cell-protein interaction would cause the arrangement of extracellular matrix and cytoskeleton changes at the interfaces.

  4. Influences of multisensory experience on subsequent unisensory processing

    Full Text Available Multisensory perception has been the focus of intense research in recent years. It is now well established that crossmodal interactions are ubiquitous in perceptual processing and endow the system with improved precision, accuracy, processing speed, etc. While these findings have shed much light on principles and mechanisms of perception, ultimately it is not very surprising that multiple sources of information provide benefits in performance compared to a single source of information.Here, we argue that the more surprising recent findings are those showing that multisensory experience also influences the subsequent unisensory processing. For example, exposure to auditory-visual stimuli, can change the way auditory or visual stimuli are processed subsequently even in isolation. We review three sets of findings that represent three different types of learning ranging from perceptual learning, to sensory recalibration, to associative learning. In all these cases exposure to multisensory stimuli profoundly influences the subsequent unisensory processing. This diversity of phenomena may suggest that continuous modification of unisensory representations by multisensory relationships may be a general learning strategy used by the brain.

    Examine parents' concerns about subsequent pregnancies after experiencing an infant or child death (newborn to 18 years). Thirty-nine semistructured parent (white, black, Hispanic) interviews 7 and 13 months post infant/child death conducted in English and/or Spanish, audio-recorded, transcribed, and content analyzed. Mothers' mean age was 31.8 years, fathers' was 39 years; 11 parents were white, 16 black, and 12 Hispanic. Themes common at 7 and 13 months: wanting more children; fear, anxiety, scared; praying to God/God's will; thinking about/keeping the infant's/child's memory and at 7 months importance of becoming pregnant for family members; and at 13 months happy about a new baby. Parents who lost a child in neonatal intensive care unit (NICU) commented more than those who lost a child in pediatric intensive care unit (PICU). Black and Hispanic parents commented more on praying to God and subsequent pregnancies being God's will than white parents. Loss of an infant/child is a significant stressor on parents with documented negative physical and mental health outcomes. Assessing parents' subsequent pregnancy plans, recognizing the legitimacy of their fears about another pregnancy, discussing a plan should they encounter problems, and carefully monitoring the health of all parents who lost an infant/child is an essential practitioner role. ©2015 American Association of Nurse Practitioners.

    Individuals react differently to social experiences; for example, people who are more sensitive to negative social experiences, such as being excluded, may be more likely to adapt their behavior to fit in with others. We examined whether functional brain connectivity during social exclusion in the fMRI scanner can be used to predict subsequent conformity to peer norms. Adolescent males (n = 57) completed a two-part study on teen driving risk: a social exclusion task (Cyberball) during an fMRI session and a subsequent driving simulator session in which they drove alone and in the presence of a peer who expressed risk-averse or risk-accepting driving norms. We computed the difference in functional connectivity between social exclusion and social inclusion from each node in the brain to nodes in two brain networks, one previously associated with mentalizing (medial prefrontal cortex, temporoparietal junction, precuneus, temporal poles) and another with social pain (dorsal anterior cingulate cortex, anterior insula). Using predictive modeling, this measure of global connectivity during exclusion predicted the extent of conformity to peer pressure during driving in the subsequent experimental session. These findings extend our understanding of how global neural dynamics guide social behavior, revealing functional network activity that captures individual differences.

    The authors wished to determine the proportion of patients with intermediate-category and intermediate-probability ventilation-perfusion scintigraphy (IVQS) who proceed to further imaging for investigation of thromboembolism, to identify the defining clinical parameters and to determine the proportion of patients who have a definite imaging diagnosis of thromboembolism prior to discharge from hospital on anticoagulation therapy. One hundred and twelve VQS studies performed at the Flinders Medical Centre over a 9-month period were reported as having intermediate category and probability for pulmonary embolism. Medical case notes were available for review in 99 of these patients and from these the pretest clinical probability, subsequent patient progress and treatment were recorded. Eight cases were excluded because they were already receiving anticoagulation therapy. In the remaining 91 patients the pretest clinical probability was considered to be low in 25; intermediate in 30; and high in 36 cases. In total, 51.6% (n = 47) of these patients (8% (n = 2) with low, 66% (n = 20) with intermediate, and 69.4% (n = 25) with high pretest probability) proceeded to CT pulmonary angiography (CTPA) and/or lower limb duplex Doppler ultrasound (DUS) evaluation. Of the patients with IVQS results, 30.7% (n 28) were evaluated with CTPA. No patient with a low, all patients with a high and 46% of patients with an intermediate pretest probability initially received anticoagulation therapy. This was discontinued in three patients with high and in 12 patients with intermediate clinical probability prior to discharge from hospital. Overall, 40% of patients discharged on anticoagulation therapy (including 39% of those with a high pretest probability) had a positive imaging diagnosis of thromboembolism The results suggest that, although the majority of patients with intermediate-to-high pretest probability and IVQS proceed to further imaging investigation, CTPA is relatively underused in

    Twenty-seven children with acute leukemia were studied in order to detect the subsequent neurologic complications due to chemotherapy and radiation therapy. Twenty-four patients with ALL received central nervous system prophylaxis including cranial irradiation. The methods of evaluation consisted of electroencephalogram (EEG), computed tomography of the head (CT scan), soft neurological sign, intelligence quotient (IQ) and Bender Gestalt test. The patients with relapse showed severe abnormalities in various kinds of examinations. Younger children at diagnosis were associated with a higher abnormality rate of soft neurological signs and Bender Gestalt test. Factors which were found to be closely associated with a lower IQ score included younger children at diagnosis and longer duration of remission time. These results indicate the need for caution for the dosage of cranial irradiation for younger patients in CNS prophylaxis, and improvement of a lower IQ score in long-term survivors requires further investigation as to the appropriate intellectual environment for their development after remission.

    Smoking is an established risk factor for a human papillomavirus (HPV) infection advancing to cervical precancer and cancer, but its role earlier in the natural history is less clear. Smoking is inversely associated with possessing HPV antibodies from a past infection suggesting that smoking may influence acquiring subsequent infections. In a cohort of 1976 U.S. women, we evaluate whether reduced antibodies to HPV-16 is a mechanism for smoking's role on acquiring a subsequent HPV-16 infection, through the analytic technique of causal mediation analysis. We posit a causal model and estimate two counterfactually defined effects: a smoking impaired antibody-mediated indirect effect and a nonmediated direct effect representing all other potential mechanisms of smoking. Compared to never smokers, current smokers had increased odds of HPV-16 infection by the antibody-mediated indirect effect (odds ratio [OR] = 1.29; 95% confidence interval [CI]: 1.11, 1.73); the estimated direct effect was very imprecise (OR = 0.57; 95% CI, 0.26-1.13). We observed a stronger estimated indirect effect among women who smoked at least half a pack of cigarettes daily (OR = 1.61, 95% CI, 1.27-2.15) than among women who smoked less than that threshold (OR = 1.09; 95% CI, 0.94-1.44). This is the first study to directly test the mechanism underlying smoking as an HPV cofactor. The results support current smoking as a risk factor earlier in the natural history of HPV and are consistent with the hypothesis that smoking increases the risk of a subsequent infection by reducing immunity.

    2018-05-01

    Full Text Available Background: Minorities’ Diminished Return (MDR theory suggests that socioeconomic position (SEP may have a smaller effect on health and well-being of members of the minority than the majority groups. Aim: Built on the MDR theory, this study compared Whites and African Americans for the effects of three family SEP indicators (family type, parental education, and parental employment during adolescence on subsequent symptoms of anxiety 18 years later during young adulthood. Methods: Flint Adolescents Study (FAS, 1994–2012, followed 359 youth (ages 13 to 17, 295 African American and 64 Whites for 18 years. The independent variables were family type, parental education, and parental employment during adolescence. The dependent variable was subsequent symptoms of anxiety, measured using the Brief Symptom Inventory (BSI, 18 years later. Age and gender were the covariates and race/ethnicity was the focal effect modifier (moderator. Four linear regression models were estimated to investigate the effects of the three family SEP indicators at age 15 on subsequent symptoms of anxiety at age 33 in the pooled sample and also by race/ethnicity. Results: In the pooled sample, having married parents at age 15 was inversely associated with symptoms of anxiety at age 33. We found an interaction between race/ethnicity and family type, indicating a smaller protective effect of having married parents against symptoms of anxiety for African American compared to White participants. The other two SEP indicators did not show any effect and did not interact with race/ethnicity on the outcome. Conclusion: In support of the MDR theory, marital status of parents during adolescence protects White but not African American young adults against anxiety symptoms. Diminished return of SEP is one of many underlying mechanisms involved in shaping racial and ethnic disparities in anxiety, however, that is often overlooked.

    Emotionally negative stimuli serve as a mechanism of biological preparedness to enhance attention. We hypothesized that emotionally negative stimuli would also serve as motivational priming to increase attention resources for subsequent stimuli. To that end, we tested 11 participants in a dual sensory modality task, wherein emotionally negative pictures were contrasted with emotionally neutral pictures and each picture was followed 600 ms later by a tone in an auditory oddball paradigm. Each trial began with a picture displayed for 200 ms; half of the trials began with an emotionally negative picture and half of the trials began with an emotionally neutral picture; 600 ms following picture presentation, the participants heard either an oddball tone or a standard tone. At the end of each trial (picture followed by tone), the participants categorized, with a button press, the picture and tone combination. As expected, and consistent with previous studies, we found an enhanced visual late positive potential (latency range=300-700 ms) to the negative picture stimuli. We further found that compared to neutral pictures, negative pictures resulted in early attention and orienting effects to subsequent tones (measured through an enhanced N1 and N2) and sustained attention effects only to the subsequent oddball tones (measured through late processing negativity, latency range=400-700 ms). Number pad responses to both the picture and tone category showed the shortest response latencies and greatest percentage of correct picture-tone categorization on the negative picture followed by oddball tone trials. Consistent with previous work on natural selective attention, our results support the idea that emotional stimuli can alter attention resource allocation. This finding has broad implications for human attention and performance as it specifically shows the conditions in which an emotionally negative stimulus can result in extended stimulus evaluation.

    The paper investigates the effect of child malnutrition on the risk of mortality in Burundi, a very poor country heavily affected by civil war. We use anthropometric data from a longitudinal survey (1998-2007). We find that undernourished children, as measured by the height-for-age z-scores (HAZ) in 1998 had a higher probability to die during subsequent years. In order to address the problem of omitted variables correlated with both nutritional status and the risk of mortality, we use the len...

  14. Radiation degration and the subsequent enzymatic hydrolysis of waste papers

    1982-01-01

    In recent years, many methods have been proposed for the hydrolysis of waste cellulose to utilize it as a new source of alcohol. Because it is difficult to hydrolyze waste cellulosic materials effectivley with an enzyme, the effects of preirradiating waste papers on subsequent enzymatic hydrolysis was studied. Preirradiation (x rays from 60 Co) accelerated the hydrolysis rate of newspaper by cellulase and the reducing-sugar yield increased with increasing irradiation dose. It is thought that preirradiation probably contributes to loosening and releasing the compactly entangled structure of cellulose and lignin in the materials by radiation degradation

    Although many studies have examined the link between parental divorce and subsequent well-being, some theories of the effects of divorce suggest that the negative associations should have declined over time. However, few studies have examined the extent to which the associations have remained stable over time. Using data from two British cohorts, we analyzed both shorter- and longer-term outcomes of children who experienced parental divorce and the extent to which the associations have changed over time. Estimating similar models for both cohorts, we found little evidence of any change in the size of the relationship as divorce became more commonplace.

    Full Text Available The objective of this study was to determine cow characteristics and farm management factors during the dry period associated with early postparturient intramammary infection (IMI and subsequent clinical mastitis (CM. Data were collected three times: before drying off (P1, during the dry period (P2, and 5 to 14 days after calving (P3, using questionnaires and farm investigation. Milk samples were aseptically collected for bacterial identification at P1 and P3. Factors associated with IMI and CM were analyzed using multiple logistic regression models. The final model showed that IMI in early postpartum was significantly associated with full insertion of dry cow antibiotic, dry cows in barns with a combination of tie and free stalls, body condition score (BCS in dry period and after calving, and milk yield before drying off. For IMI cows, factors significantly associated with clinical expression of mastitis were having daily barn cleaning, teat disinfected with alcohol before administration of dry cow therapy, BCS before drying off, milk yield before drying off, and days in milk at drying off. In conclusion, both cow and farm management factors are associated with the IMI rate and subsequent expression of clinical signs of mastitis in early postpartum cows.

  17. Recurrent hypoglycemia increases anxiety and amygdala norepinephrine release during subsequent hypoglycemia

    Full Text Available Recurrent hypoglycemia (RH is a common and debilitating side effect of therapy in patients with both type 1 and, increasingly, type 2 diabetes. Previous studies in rats have shown marked effects of RH on subsequent hippocampal behavioral, metabolic, and synaptic processes. In addition to impaired memory, patients experiencing RH report alterations in cognitive processes that include mood and anxiety, suggesting that RH may also affect amygdala function. We tested the impact of RH on amygdala function using an elevated plus-maze test of anxiety together with in vivo amygdala microdialysis for norepinephrine (NEp, a widely used marker of basolateral amygdala cognitive processes. In contrast to findings in the hippocampus and pre-frontal cortex, neither RH nor acute hypoglycemia alone significantly affected plus-maze performance or NEp release. However, animals tested when hypoglycemic who had previously experienced RH had elevated amygdala NEp during plus-maze testing, accompanied by increased anxiety (i.e. less time spent in the open arms of the plus-maze. The results show that RH has widespread effects on subsequent brain function, which vary by neural system.

    The present paper delves into the question of whether and to what extent it is appropriate to leave addiction problems between the conflicting priorities of therapy and criminalization. After outlining the issue the criminal addictive behaviour including crimes associated with drug misuse and with obtaining drugs is described. Subsequently it is discussed if and how you could make allowances for addiction-related legal insanity in the criminal law sector. Following a few remarks on the principle of "voluntary therapy instead of penal sanction" as a way to alleviate the strict law on narcotic drugs misuse a summary and an outlook with criminal-political demands complete the issue.

    Fractures in elderly are always a dramatic event and the healing is often not complete. In a context of bone fragility, repeated fractures are a growing problem in the industrialized world, in which the mean age of population is increasing. The aim of this study was to identify those general factors which may increase the risk of subsequent trochanteric fractures after an initial lesion. Three-hundred and thirty-one patients who underwent intramedullary fixation for trochanteric fractures between January 2012 and December 2013 were studied. Forty subjects yet alive (group 1), affected by a subsequent contralateral hip fracture, were compared with 202 patients (group 2) affected by isolated trochanteric fracture. Days of hospitalization before surgery, hospitalization, period of rehabilitation, type of discharge and comorbidities, that are reported in literature as possible risk factors for hip refracture, were analyzed. In addition, all patients were interviewed in order to assess if a therapy for osteoporosis was prescribed after the initial fracture and how their gait had been modified by fractures. Days of hospitalization before surgery, hospitalization, period of rehabilitation and type of discharge were not predictive factors for subsequent fractures, as well as diabetes mellitus, hypertension and cardiac diseases. The presence of neurologic and respiratory diseases were associated to a higher risk of refractures, as well as the absence of specific medical treatment for osteoporosis. Neurologic and respiratory comorbidities and the absence of osteoporosis medical treatment are the variables associated to a higher risk of contralateral fractures. Physicians can do more in terms of prevention and strategies must consider these risk factors.

    The aim of our study was to evaluate the relationship between routine treatment of periodontal disease (PD) and the subsequent risks for cancers in Taiwan. Study participants were selected from the Taiwan National Health Insurance (NHI) system database. The PD with a routine treatment cohort contained 38 902 patients. For each treatment cohort participant, two age- and sex-matched comparison (control) cohort participants were randomly selected. Cox's proportional hazards regression analysis was used to estimate the effects of PD with treatment on the subsequent risk of cancer. The overall risk of developing cancer was significantly lower in the treatment cohort than in the patients without treatment (adjusted Hazard ratio = 0.72, 95% confidence interval = 0.68-0.76). The risks of developing most gastrointestinal tract, lung, gynecological and brain malignancies were significantly lower in the treatment cohort than in the comparison cohort. In contrast, the risks of prostate and thyroid cancers were significantly higher in the treatment cohort than in the comparison cohort. Our findings suggest that PD with treatment is associated with a significantly reduced overall risk of cancer and reduced risks of certain types of cancers. © The Author 2014.

    2017-01-01

    Low temperature (LT) flow modulation epitaxy (FME) or "pulsed" growth was successfully used to prevent magnesium from Metalorganic Chemical Vapor Deposition (MOCVD) grown p-GaN:Mg layers riding into subsequently deposited n-type layers. Mg concentration in the subsequent layers was lowered from ˜1 × 1018 cm-3 for a medium temperature growth at 950 °C to ˜1 × 1016 cm-3 for a low temperature growth at 700 °C via FME. The slope of the Mg concentration drop in the 700 °C FME sample was 20 nm/dec—the lowest ever demonstrated by MOCVD. For growth on Mg implanted GaN layers, the drop for a medium temperature regrowth at 950 °C was ˜10 nm/dec compared to >120 nm/dec for a high temperature regrowth at 1150 °C. This drop-rate obtained at 950 °C or lower was maintained even when the growth temperature in the following layers was raised to 1150 °C. A controlled silicon doping series using LT FME was also demonstrated with the lowest and highest achieved doping levels being 5 × 1016 cm-3 and 6 × 1019 cm-3, respectively.

  2. Transported biofilms and their influence on subsequent macrofouling colonization.

    2017-05-01

    Biofilm organisms such as diatoms are potential regulators of global macrofouling dispersal because they ubiquitously colonize submerged surfaces, resist antifouling efforts and frequently alter larval recruitment. Although ships continually deliver biofilms to foreign ports, it is unclear how transport shapes biofilm microbial structure and subsequent macrofouling colonization. This study demonstrates that different ship hull coatings and transport methods change diatom assemblage composition in transported coastal marine biofilms. Assemblages carried on the hull experienced significant cell losses and changes in composition through hydrodynamic stress, whereas those that underwent sheltered transport, even through freshwater, were largely unaltered. Coatings and their associated biofilms shaped distinct macrofouling communities and affected recruitment for one third of all species, while biofilms from different transport treatments had little effect on macrofouling colonization. These results demonstrate that transport conditions can shape diatom assemblages in biofilms carried by ships, but the properties of the underlying coatings are mainly responsible for subsequent macrofouling. The methods by which organisms colonize and are transferred by ships have implications for their distribution, establishment and invasion success.

    Splenectomy may be necessary to treat systemic lupus erythematosus (SLE) patients with thrombocytopenia; however, whether performing a splenectomy on patients without SLE increases the subsequent risk of SLE remains unknown. Therefore, this study was conducted to determine the association between splenectomy and SLE. We conducted a cohort study by using data from the Taiwan National Health Institute Research Database to identify 10,298 patients with received a splenectomy between 2000 and 2006 and 41,192 participants without received a splenectomy who were selected by frequency matched based on sex, age, and the index year. Cox proportional hazards models were used to estimate the hazard ratios (HRs) and 95 % confidence intervals (CIs) of developing SLE associated with splenectomy compared with patients who did not receive a splenectomy. During the study period, the overall incidence density rate of SLE was higher in the splenectomy cohort than in the non-splenectomy cohort (adjusted HR 10.55; 95 % CI 50.55-20.05). The incidence density rates of SLE in women and men who received a splenectomy were higher than those of patients who did not receive a splenectomy. Non-traumatic splenectomy increases the subsequent risk of SLE. The risk of SLE should be considered before performing a splenectomy, particularly in women and younger patients.

  4. Play Therapy

    Play therapy is a treatment modality in which the therapist engages in play with the child. Its use has been documented in a variety of settings and with a variety of diagnoses. Treating within the context of play brings the therapist and the therapy to the level of the child. By way of an introduction to this approach, a case is presented of a six-year-old boy with oppositional defiant disorder. The presentation focuses on the events and interactions of a typical session with an established patient. The primary issues of the session are aggression, self worth, and self efficacy. These themes manifest themselves through the content of the child’s play and narration of his actions. The therapist then reflects these back to the child while gently encouraging the child toward more positive play. Though the example is one of nondirective play therapy, a wide range of variation exists under the heading of play therapy. PMID:19724720

    interventions of media alone as well as through the intervention of media in conjunction with personal support within the groups. However, analyses of the inter-group comparisons offer no statistically significant difference. However, analyses of the inter-group comparisons offer no statistically significant difference. Comparative analyses confirm the effectiveness of behaviour therapy in combination with additional drug treatment when compared to behaviour therapy alone.In all the studies presented here, relevant changes in weight of -5% to -10% are only partially achieved. High weight losses of less than -10% were found among the intervention group in two of the studies. One study reported a weight loss of -11.4% with the “group therapy” intervention method, while another study reported a weight loss of -11.2% with the “behaviour therapy plus drug treatment” intervention method. Studies with a subsequent follow-up period indicate a clear weight loss at the end of the intervention followed by a renewed weight gain towards the end of the follow-up period.For the evaluation of economic, social-ethical or legal aspects we could not identify any studies. Discussion: A comparative assessment among the studies proved difficult due to their heterogeneous nature. Little conformity can be detected in either the contents of the behaviour therapy or in the treatment plans. The length of the follow-up periods also varies from study to study. Many studies only analyze weight changes within one group or for the entire study population. However, the results of these analyses all indicate a significant weight loss at the end of the intervention. Conclusion: Some effects of behaviour therapy on a reduction in weight can be shown. However, relevant weight changes of -5% to -10% are only achieved to a certain extent. The extremely heterogeneous nature of the interventions makes a comparison of the study results very difficult. A trend can be detected indicates that those treatments

    The digital health landscape in the United States is evolving and electronic health record data hold great promise for improving health and health equity. Like many scientific and technological advances in health and medicine, there exists an exciting narrative about what we can do with the new technology, as well as reflection about what we should do with it based on what we value. Ethical reflections about the use of EHR data for research and quality improvement have considered the important issues of privacy and informed consent for subsequent use of data. Additional ethical aspects are important in the conversation, including data validity, patient obligation to participate in the learning health system, and ethics integration into training for all personnel who interact with personal health data. Attention to these ethical issues is paramount to our realizing the benefits of electronic health data. Published by Elsevier Inc.

    1986-01-01

    B. subtilis spores exposed to thermal treatment at 70 or 80 0 C for 1 hr were more sensitive to subsequent radiation exposure than non-heated spores. Deactivation of previously heated spores by increasing dose of 0-radiation followed an exponential function while, for non-heated spores a shoulder followed by exponential deactivation was noticed. Combined heat-radiation treatment exhibited a synergistic effect on spore deactivation at low irradiation doses, while at high irradiation doses, the effect was more or less additive. Added values of spore injury was higher for B. subtilis spores that received heat and radiation separately than the observed injury for spores that received combined treatment (heat followed by radiation). Results of spore deactivation and injury due to heat followed by radiation treatment are discussed in comparison to those of spores that received radiation-heat sequence

    This study follows the occurrence of refractive errors in population and the possible selection of the appropriate type of corrective aids. Objective measurement and subsequent determination of the subjective refraction of the eye is on essential act in opotmetric practice. The file represented by 615 patients (1230 eyes) is divided according to the refractive error of myopia, hyperopia and as a control group are listed emetropic clients. The results of objective and subjective values of refraction are compared and statistically processed. The study included 615 respondents. To determine the objective refraction the autorefraktokeratometer with Placido disc was used and the values of spherical and astigmatic correction components, including the axis were recorded. These measurements were subsequently verified and tested subjectively using the trial lenses and the projection optotype to the normal investigative distance of 5 meters. After this the appropriate corrective aids were then recommended. Group I consists of 123 men and 195 women with myopia (n = 635) of clients with an average age 39 +/- 18,9 years. Objective refraction - sphere: -2,57 +/- 2,46 D, cylinder: -1,1 +/- 1,01 D, axis of: 100 degrees +/- 53,16 degrees. Subjective results are as follows--the value of sphere: -2,28 +/- 2,33 D, cylinder -0,63 +/- 0,80 D, axis of: 99,8 degrees +/- 56,64 degrees. Group II is represented hyperopic clients and consists of 67 men and 107 women (n = 348). The average age is 58,84 +/- 16,73 years. Objective refraction has values - sphere: +2,81 +/- 2,21 D, cylinder: -1,0 +/- 0,94 D; axis 95 degree +/- 45,4 degrees. Subsequent determination of subjective refraction has the following results - sphere: +2,28 +/- 2,06 D; cylinder: -0,49 +/- 0,85 D, axis of: 95,9 degrees +/- 46,4 degrees. Group III consists from emetropes whose final minimum viasual acuity was Vmin = 1,0 (5/5) or better. Overall, this control group is represented 52 males and 71 females (n = 247). The average

    Full Text Available Recent research has demonstrated that the cognitive processes associated with goal pursuit can continue to interfere with unrelated tasks when a goal is unfulfilled. Drawing from the self-regulation and goal-striving literatures, the present study explored the impact of goal failure on subsequent cognitive and physical task performance. Furthermore, we examined if the autonomous or controlled motivation underpinning goal striving moderates the responses to goal failure. Athletes (75 male, 59 female, Mage = 19.90 years, SDage = 3.50 completed a cycling trial with the goal of covering a given distance in 8 minutes. Prior to the trial, their motivation was primed using a video. During the trial they were provided with manipulated performance feedback, thus creating conditions of goal success or failure. No differences emerged in the responses to goal failure between the primed motivation or performance feedback conditions. We make recommendations for future research into how individuals can deal with failure in goal striving.

  14. SWAMP+: multiple subsequence alignment using associative massive parallelism

    2010-10-18

    A new parallel algorithm SWAMP+ incorporates the Smith-Waterman sequence alignment on an associative parallel model known as ASC. It is a highly sensitive parallel approach that expands traditional pairwise sequence alignment. This is the first parallel algorithm to provide multiple non-overlapping, non-intersecting subsequence alignments with the accuracy of Smith-Waterman. The efficient algorithm provides multiple alignments similar to BLAST while creating a better workflow for the end users. The parallel portions of the code run in O(m+n) time using m processors. When m = n, the algorithmic analysis becomes O(n) with a coefficient of two, yielding a linear speedup. Implementation of the algorithm on the SIMD ClearSpeed CSX620 confirms this theoretical linear speedup with real timings.

    Although antibiotics have significantly improved human health and life expectancy, their disruption of the existing microbiota has been linked to significant side effects such as antibiotic-associated diarrhea, pseudomembranous colitis, and increased susceptibility to subsequent disease. By using antibiotics to break colonization resistance against Clostridium, Salmonella, and Citrobacter species, researchers are now exploring mechanisms for microbiota-mediated modulation against pathogenic infection, revealing potential roles for different phyla and family members as well as microbiota-liberated sugars, hormones, and short-chain fatty acids in regulating pathogenicity. Furthermore, connections are now being made between microbiota dysbiosis and a variety of different diseases such as rheumatoid arthritis, inflammatory bowel disease, type 1 diabetes, atopy, and obesity. Future advances in the rapidly developing field of microbial bioinformatics will enable researchers to further characterize the mechanisms of microbiota modulation of disease and potentially identify novel therapeutics against disease.

    Empathy is related to a variety of prosocial behaviors, but the brain mechanisms producing the experience of empathy have not been fully characterized. This study investigated whether the experience of empathy raises oxytocin levels and affects subsequent generosity toward strangers. Short video clips of an emotional scene and an unemotional scene were used as stimuli. Participants rated the emotions they experienced and then played a $40 ultimatum game to gauge their generosity. We found that empathy was associated with a 47% increase in oxytocin from baseline. We also found the empathy-oxytocin response was stronger in women than in men. Higher levels of empathy were also associated with more generous monetary offers toward strangers in the ultimatum game. Our findings provide the first evidence that oxytocin is a physiologic signature for empathy and that empathy mediates generosity.

    Full Text Available Neighborhood development is primarily comprised of structural elements that include design elements, nearby amenities and ecological attributes. This paper assumes that the process of development itself also influences the character of the neighborhood—specifically, that the rate of development and build-out ratio influences neighborhood turnover. While the structural components clearly set a framework for development, the process of development expresses the character of the neighborhood in subtle messages conveyed through the market. Neighborhoods in the rapidly growing university town of College Station, Texas are analyzed in terms of neighborhood design, nearby amenities and landscape ecology components. Residential property records are used to characterize each neighborhood in terms of the rate of development and current build-out ratio. The multivariate analysis indicates that the development rate increases subsequent neighborhood turnover rates while the build-out ratio decreases it.

    Understanding the influence of strength training intensity on subsequent recovery in elderly is important to avoid reductions in physical function during the days following training. Twenty-two elderly were randomized in two groups: G70 (65.9 ± 4.8 years, n = 11) and G95 (66.9 ± 5.1, n = 11...... in elderly depending on the type of physical function and intensity of training. Higher intensity resulted in greater impairment. Exercise prescription in elderly should take this into account, e.g., by gradually increasing intensity during the first months of strength training. These results have relevance...... for elderly who have to be fit for work or other activities in the days following strength training....

    2013-07-01

    The risk that abortion may be correlated with subsequent mental disorders needs a careful assessment, in order to offer women full information when facing a difficult pregnancy. All research papers published between 1995 and 2011, were examined, to retrieve those assessing any correlation between abortion and subsequent mental problems. A total of 36 studies were retrieved, and six of them were excluded for methodological bias. Depression, anxiety disorders (e.g. post-traumatic stress disorder) and substance abuse disorders were the most studied outcome. Abortion versus childbirth: 13 studies showed a clear risk for at least one of the reported mental problems in the abortion group versus childbirth, five papers showed no difference, in particular if women do not consider their experience of fetal loss to be difficult, or if after a fetal reduction the desired fetus survives. Only one paper reported a worse mental outcome for childbearing. Abortion versus unplanned pregnancies ending with childbirth: four studies found a higher risk in the abortion groups and three, no difference. Abortion versus miscarriage: three studies showed a greater risk of mental disorders due to abortion, four found no difference and two found that short-term anxiety and depression were higher in the miscarriage group, while long-term anxiety and depression were present only in the abortion group. In conclusion, fetal loss seems to expose women to a higher risk for mental disorders than childbirth; some studies show that abortion can be considered a more relevant risk factor than miscarriage; more research is needed in this field. © 2013 The Authors.

    Dextrose gel is increasingly used as first-line treatment for neonatal hypoglycaemia. Treatment with 400 mg/kg previously has been reported to impair subsequent feeding. We sought to determine if the recommended dose of 200 mg/kg altered feeding. Hypoglycaemic babies were randomised to 200 mg/kg dextrose gel or placebo and fed. Prefeed alertness, quality and duration of breast feeding, and the volume of formula taken were assessed on the next feeding. Prefeed alertness scores were similar in babies (n=211) treated with dextrose or placebo gel (124 episodes, OR=1.30 (95% CI 0.62 to 2.77), p=0.49). Breastfed babies were more likely to have good feeding scores after dextrose gel (160 episodes, OR=3.54 (95% CI 1.30 to 9.67), p=0.01) but similar breastfeeding duration (57 episodes, median (range) 20 (3-90) vs 25 (2-80) min, p=0.62). Formula volumes taken were also similar (24 episodes, median (range) 4.6 (2.2-11.3) vs 6.4 (2.0-8.9) mL/kg, p=0.30). Treating hypoglycaemic babies with dextrose gel 200 mg/kg does not depress subsequent feeding and may improve breastfeeding quality.

    Epilepsy, febrile seizures, and attention-deficit/hyperactivity disorder (ADHD) are disorders of the central nervous system and share common risk factors. Our goal was to examine the association in a nationwide cohort study with prospective follow-up and adjustment for selected confounders. We hypothesized that epilepsy and febrile seizures were associated with subsequent ADHD. A population-based cohort of all children born in Denmark from 1990 through 2007 was followed up until 2012. Incidence rate ratios (IRRs) and 95% confidence intervals (95% CIs) for ADHD were estimated by using Cox regression analysis, comparing children with epilepsy and febrile seizure with those without these disorders, adjusted for socioeconomic and perinatal risk factors, as well as family history of neurologic and psychiatric disorders. A total of 906 379 individuals were followed up for 22 years (∼10 million person-years of observation); 21 079 individuals developed ADHD. Children with epilepsy had a fully adjusted IRR of ADHD of 2.72 (95% CI, 2.53-2.91) compared with children without epilepsy. Similarly, in children with febrile seizure, the fully adjusted IRR of ADHD was 1.28 (95% CI, 1.20-1.35). In individuals with both epilepsy and febrile seizure, the fully adjusted IRR of ADHD was 3.22 (95% CI, 2.72-3.83). Our findings indicate a strong association between epilepsy in childhood and, to a lesser extent, febrile seizure and subsequent development of ADHD, even after adjusting for socioeconomic and perinatal risk factors, and family history of epilepsy, febrile seizures, or psychiatric disorders.

    A number of successful systemic therapies are available for treatment of disseminated cancers. However, tumor response is often transient, and therapy frequently fails due to emergence of resistant populations. The latter reflects the temporal and spatial heterogeneity of the tumor microenvironment as well as the evolutionary capacity of cancer phenotypes to adapt to therapeutic perturbations. Although cancers are highly dynamic systems, cancer therapy is typically administered according to a fixed, linear protocol. Here we examine an adaptive therapeutic approach that evolves in response to the temporal and spatial variability of tumor microenvironment and cellular phenotype as well as therapy-induced perturbations. Initial mathematical models find that when resistant phenotypes arise in the untreated tumor, they are typically present in small numbers because they are less fit than the sensitive population. This reflects the "cost" of phenotypic resistance such as additional substrate and energy used to up-regulate xenobiotic metabolism, and therefore not available for proliferation, or the growth inhibitory nature of environments (i.e., ischemia or hypoxia) that confer resistance on phenotypically sensitive cells. Thus, in the Darwinian environment of a cancer, the fitter chemosensitive cells will ordinarily proliferate at the expense of the less fit chemoresistant cells. The models show that, if resistant populations are present before administration of therapy, treatments designed to kill maximum numbers of cancer cells remove this inhibitory effect and actually promote more rapid growth of the resistant populations. We present an alternative approach in which treatment is continuously modulated to achieve a fixed tumor population. The goal of adaptive therapy is to enforce a stable tumor burden by permitting a significant population of chemosensitive cells to survive so that they, in turn, suppress proliferation of the less fit but chemoresistant

    This chapter first summarizes the therapy of addiction disorder, and elaborates on the progress of medication. First, the difference between dependency and addiction are introduced. The basic principles of the therapy of substance and non-substance addiction are then put forward. It is also pointed out in this chapter that with the progress of the study, the goal of addiction disorder therapy is expected to transfer from reducing the relapse and harm of the addiction to completely eliminating and recovering from it. This chapter also introduces the progress of psychological addiction elimination technology, especially the "Unconditioned Stimulus Retrieval Extinction Paradigm and Conditioned Stimulus Retrieval Extinction Paradigm" and PITDH technology. Finally it is pointed out that in addiction disorder therapy, comprehensive intervention has become a trend. With regard to the medication for addiction disorders, this chapter also includes the progress and deficiencies of substance and non-substance addiction. In terms of addiction disorder rehabilitation, the foundation of substance addiction is medication which is, however, limited for non-substance addiction. The key to the rehabilitation of addiction disorder is psycho-behavioral therapy, which is especially effective in eliminating craving.

  7. Neutron therapy

    Standard radiotherapy uses Xrays or electrons which have low LET (linear energy transfer); in contrast, particles such as neutrons with high LET have different radiobiological responses. In the late 1960s, clinical trials by Mary Catterall at the Hammersmith Hospital in London indicated that fast neutron radiation had clinical advantages for certain malignant tumours. Following these early clinical trials, several cyclotron facilities were built in the 1980s for fast neutron therapy, for example at the University of Washington, Seattle, and at UCLA. Most of these newer machines use extracted cyclotron proton beams in the range 42 to 66 MeV with beam intensities of 15 to 60 microamps. The proton beams are transported to dedicated therapy rooms, where neutrons are produced from beryllium targets. Second-generation clinical trials showed that accurate neutron beam delivery to the tumour site is more critical than for photon therapy. In order to achieve precise beam geometries, the extracted proton beams have to be transported through a gantry which can rotate around the patient and deliver beams from any angle; also the neutron beam outline (''field shape'') must be adjusted to extremely irregular shapes using a flexible collimation system. A therapy procedure has to be appropriately organized, with physicians, radiotherapists, nurses, medical physicists and other staff in attendance; other specialized equipment, such as CT or MRI scanners and radiation simulators must be made available. Neutron therapy is usually performed only in radiation oncology departments of major medical centres

    Ethanol is important both forensically ('drunk driving' or driving while under the influence, 'DWI', regulations) and commercially (alcoholic beverages). Blood- and breath-alcohol testing can be imposed on individuals operating private vehicles such as cars, boats, or snowmobiles, or operators of commercial vehicles like trucks, planes, and ships. The various levels of blood alcohol that determine whether these operators are considered legally impaired vary depending on the circumstances and locality. Accurate calibration and validation of instrumentation is critical in areas of forensic testing where quantitative analysis directly affects the outcome of criminal prosecutions, as is the case with the determination of ethanol in blood and breath. Additionally, the accurate assessment of the alcoholic content of beverages is a commercially important commodity. In 2002, the CCQM conducted a Key Comparison (CCQM-K27) for the determination of ethanol in aqueous matrix with nine participants. A report on this project has been approved by the CCQM and can be found at the BIPM website and in this Technical Supplement. CCQM-K27 comprised three samples, one at low mass fraction of ethanol in water (nominal concentration of 0.8 mg/g), one at high level (nominal concentration of 120 mg/g), and one wine matrix (nominal concentration of 81 mg/g). Overall agreement among eight participants using gas chromatography with flame ionization detection (GC-FID), titrimetry, isotope dilution gas chromatography/mass spectrometry (GC-IDMS), and gas chromatography-combustion-isotope ratio mass spectrometry (ID-GC-C-IRMS) was good. The ninth participant used a headspace GC-FID method that had not been validated in an earlier pilot study (CCQM-P35). A follow-on Key Comparison, CCQM-K27-Subsequent, was initiated in 2003 to accommodate laboratories that had not been ready to benchmark their methods in the original CCQM-K27 study or that wished to benchmark a different method.

    Deep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT) is a method of neuromodulation used for refractory focal epilepsy. We report a patient suffering from drug-resistant epilepsy who developed novel visual symptoms and atypical seizures with the onset of ANT-DBS therapy. Rechallenge under video electroencephalography recording confirmed that lowering the stimulation voltage alleviated these symptoms. Subsequent stimulation with the initial voltage value did not cause the recurrence of either the visual symptoms or the new seizure type, and appeared to alleviate the patient's seizures in long-term follow-up. We therefore hypothesize that the occurrence of stimulation induced seizures at the onset of DBS therapy should not be considered as a failure in the DBS therapy, and the possibility of a subsequent favorable response to the treatment still exists.

    Full Text Available Deep brain stimulation (DBS of the anterior nucleus of the thalamus (ANT is a method of neuromodulation used for refractory focal epilepsy. We report a patient suffering from drug-resistant epilepsy who developed novel visual symptoms and atypical seizures with the onset of ANT-DBS therapy. Rechallenge under video electroencephalography recording confirmed that lowering the stimulation voltage alleviated these symptoms. Subsequent stimulation with the initial voltage value did not cause the recurrence of either the visual symptoms or the new seizure type, and appeared to alleviate the patient’s seizures in long-term follow-up. We therefore hypothesize that the occurrence of stimulation induced seizures at the onset of DBS therapy should not be considered as a failure in the DBS therapy, and the possibility of a subsequent favorable response to the treatment still exists.

    Abstract Based on a Jungian approach, this article will introduce an integrative model to therapeutic change using art therapy methods as practical tools, with the aim of improving quality of life and in the prevention of depression. In a research study involving six participants, painting, clay...... work and drumming were used together with imagination and personal dialogues linked to the artwork. These art therapy processes attempted to combine the participant’s experience of inner and outer reality. The effect of gaining more knowledge about their inner reality using dreams and symbols......, was that participants gained a new understanding about their personal life. In addition, some participants were able to continue to use art therapy experiences as selfdevelopmental tools after the research study terminated.

    Full Text Available LTOT is prescribed for people with chronic lung disease in whom there is a decrease in the ability of the lungs to supply enough oxygen to the body. The heart is obliged to pump faster to meet the body's oxygen requirements. This may place undue stress on the heart, resulting in palpitations, dizziness and fatigue. A low oxygen level in arterial blood is also harmful to the heart, the brain and the pulmonary blood vessels. Oxygen therapy is used to break this cycle. A person with low blood oxygen will often be able to accomplish more with less fatigue with the help of supplemental oxygen therapy. Shortness of breath is a mechanical problem resulting from the effects of chronic obstructive pulmonary disease. Oxygen therapy may or may not reduce shortness of breath, but it will help the lungs and heart to function with less stress.

    IMPORTANCE It is clear that mental disorders in treatment settings are associated with a higher incidence of chronic physical conditions, but whether this is true of mental disorders in the community, and how generalized (across a range of physical health outcomes) these associations are, is less clear. This information has important implications for mental health care and the primary prevention of chronic physical disease. OBJECTIVE To investigate associations of 16 temporally prior DSM-IV mental disorders with the subsequent onset or diagnosis of 10 chronic physical conditions. DESIGN, SETTING, AND PARTICIPANTS Eighteen face-to-face, cross-sectional household surveys of community-dwelling adults were conducted in 17 countries (47 609 individuals; 2 032 942 person-years) from January 1, 2001, to December 31, 2011. The Composite International Diagnostic Interview was used to retrospectively assess the lifetime prevalence and age at onset of DSM-IV–identified mental disorders. Data analysis was performed from January 3, 2012, to September 30, 2015. MAIN OUTCOMES AND MEASURES Lifetime history of physical conditions was ascertained via self-report of physician’s diagnosis and year of onset or diagnosis. Survival analyses estimated the associations of temporally prior first onset of mental disorders with subsequent onset or diagnosis of physical conditions. RESULTS Most associations between 16 mental disorders and subsequent onset or diagnosis of 10 physical conditions were statistically significant, with odds ratios (ORs) (95% CIs) ranging from 1.2 (1.0–1.5) to 3.6 (2.0–6.6). The associations were attenuated after adjustment for mental disorder comorbidity, but mood, anxiety, substance use, and impulse control disorders remained significantly associated with onset of between 7 and all 10 of the physical conditions (ORs [95% CIs] from 1.2 [1.1–1.3] to 2.0 [1.4–2.8]). An increasing number of mental disorders experienced over the life course was significantly

    2008-11-01

    In studies aimed at assessing the accuracy and repeatability of non-contact tonometers, the order in which these tonometers and the Goldmann tonometer are used is usually randomised despite studies in the literature that demonstrate an ocular massage effect that occurs post-applanation but not after non-contact tonometry. The purpose of this study was to investigate the effect of repeated corneal applanation on subsequent assessments of IOP. Data were obtained from 65 left eyes of 65 young, oculovisual normals. Three sets of IOP measurements were obtained, one set with the Goldmann applanation tonometer and two with the Topcon CT80 non-contact tonometer (one set each before and after applanation with the Goldmann tonometer), in each one of two separate measurement sessions, one week apart. The average (and SD) IOP measured with the Goldmann tonometer in the first session (14.8+/-2.9 mmHg) did not vary significantly from the IOP measured with the non-contact tonometer (pre-applanation) in both sessions or with the average Goldmann IOP in the second session. The bias (mean difference +/- SD) between methods was 0.3+/-1.4 mmHg and 0.4+/-1.4 mmHg, respectively, for the first and second sessions, with the CT80 (pre-applanation) recording the higher IOP in both sessions. The within-session repeatability coefficients were +/-2.3 mmHg, +/-2.6 mmHg, +/-2.1 mmHg and +/-2.0 mmHg for the CT80 (pre-applanation) in the first and second sessions, and the Goldmann tonometer in the first and second sessions, respectively. Test-retest repeatability coefficients were +/-2.8 mmHg and +/-2.5 mmHg for the CT80 (pre-applanation) and the Goldmann tonometer respectively. Post-applanation with the Goldmann tonometer, there was a statistically significant (pcontact tonometer in both sessions. These results suggest that repeated corneal applanation leads to a statistically significant reduction in IOP on subsequent measurements.

Secondary Objective was to study the maternal and foetal complications following shorter interpregnancy interval. MATERIALS AND METHODS This study was done in OBG Department, Government TD Medical College, Alappuzha, during 2011 to 2013. A total of 347 cases were studied who have had a miscarriage before the current pregnancy. RESULTS Compared with women with an interpregnancy interval of 6-12 months, those who conceived again within six months were more likely to have another miscarriage and ectopic gestation (odds ratio 0.106, p value 0.000.. Compared with women with interpregnancy interval of <6 months, women who conceived again in 6-12 months went on to have a vaginal delivery in the second pregnancy (Odd’s ratio 0.79 and p value in is significant.Lower segment caesarean section (LSCS is significantly high in women whose interpregnancy interval is more than 12 months (Odds ratio 0.64 and p value 0.000.

    The new insights and controversies concerning the radiobiological properties of malignant melanoma and how these relate to new clinical approaches are reviewed. The recent clinical experience with large individual fraction sizes is analyzed. The treatment of malignant melanoma in certain specialized sites is also described. An attempt is made to place in perspective the usefulness of radiation therapy in the treatment of this complex disease. Finally, certain new applications for radiation therapy both alone and in combustion with other treatment modalities are proposed that may ultimately prove appropriate for clinical trials

    This experiment studied congenital transmission in sheep experimentally infected with oocysts of Toxoplasma gondii and reinfected at one of three stages of pregnancy. Twenty ewes were experimentally infected with T. gondii strain ME49 (day 0). After the T. gondii infection became chronic (IFAT≤512), the ewes were allocated with rams for coverage. After the diagnosis of pregnancy, these ewes were allocated into four experimental groups (n = 5): I-reinfected with T. gondii on the 40th day of gestation (DG); II-reinfected on DG 80; III-reinfected on DG 120; and IV-saline solution on DG 120 (not reinfected). Five ewes (IFATewes produced lambs serologically positive for T. gondii. The results of the mouse bioassay, immunohistochemistry and PCR assays revealed the presence of T. gondii in all 20 sheep and their lambs. The congenital transmission of T. gondii was associated with fetal loss and abnormalities in persistently infected sheep and in ewes infected and subsequently reinfected by this protozoan. Therefore, congenital T. gondii infection was common when ewes were chronically infected prior to pregnancy, with or without reinfection during at various stages of gestation.

    Although psychotic experiences in people without diagnosed mental health problems are associated with mental health service use, few studies have assessed this prospectively or measured service use by real-world clinical data. To describe and investigate the association between psychotic experiences and later mental health service use, and to assess the role of symptoms of common mental health disorders in this association. We linked a representative survey of south-east London (SELCoH-1, n =1698) with health records from the local mental healthcare provider. Cox regression estimated the association of PEs with rate of mental health service use. After adjustments, psychotic experiences were associated with a 1.75-fold increase in the rate of subsequent mental health service use (hazard ratio (HR) 1.75, 95% CI 1.03-2.97) compared with those without PEs. Participants with PEs experienced longer care episodes compared with those without. Psychotic experiences in the general population are important predictors of public mental health need, aside from their relevance for psychoses. We found psychotic experiences to be associated with later mental health service use, after accounting for sociodemographic confounders and concurrent psychopathology.

    The extent to which abortion has harmful consequences for mental health remains controversial. We aimed to examine the linkages between having an abortion and mental health outcomes over the interval from age 15-25 years. Data were gathered as part of the Christchurch Health and Development Study, a 25-year longitudinal study of a birth cohort of New Zealand children. Information was obtained on: a) the history of pregnancy/abortion for female participants over the interval from 15-25 years; b) measures of DSM-IV mental disorders and suicidal behaviour over the intervals 15-18, 18-21 and 21-25 years; and c) childhood, family and related confounding factors. Forty-one percent of women had become pregnant on at least one occasion prior to age 25, with 14.6% having an abortion. Those having an abortion had elevated rates of subsequent mental health problems including depression, anxiety, suicidal behaviours and substance use disorders. This association persisted after adjustment for confounding factors. The findings suggest that abortion in young women may be associated with increased risks of mental health problems.

    It is well known that successful retrieval enhances subsequent adults' learning by promoting long-term retention. Recent research has also found benefits from unsuccessful retrieval, but the evidence is not as clear-cut when the participants are children. In this study, we employed a methodology based on guessing-the weak associate paradigm-to test whether children can learn from generated errors or whether errors are harmful for learning. We tested second- and third-grade children in Experiment 1 and tested preschool and kindergarten children in Experiment 2. With slight differences in the method, in both experiments children heard the experimenter saying one word (cue) and were asked to guess an associate word (guess condition) or to listen to the correspondent target-associated word (study condition), followed by corrective feedback in both conditions. At the end of the guessing phase, the children undertook a cued-recall task in which they were presented with each cue and were asked to say the corrected target. Together, the results showed that older children-those in kindergarten and early elementary school-benefited from unsuccessful retrieval. Older children showed more correct responses and fewer errors in the guess condition. In contrast, preschoolers produced similar levels of correct and error responses in the two conditions. In conclusion, generating errors seems to be beneficial for future learning of children older than 5years. Copyright © 2017 Elsevier Inc. All rights reserved.

    Previous research suggests that cervical cancer patients have a lower risk of breast cancer than women in the general population. Possible explanations include opposing risk factors for cervical cancer and breast cancer, the effect of irradiation used to treat cervical cancer, or both. The purpose of this study was to explore the relationship between irradiation for cervical cancer and the subsequent development of breast cancer. There was no statistically significant relationship between radiation to the ovarian area and the risk of breast cancer in this study. However, the results were consistent with a 19% reduction in risk for women irradiated for cervical cancer when compared to nonirradiated women. In a dose-response analysis, there was a nonsignificant trend of decreased risk of breast cancer with increased radiation up to 1800 rad. There was no consistent pattern for higher doses. The trend, although nonsignificant, differed by age. Women <60 years of age at irradiation were generally at a lower risk of breast cancer than nonirradiated women. Women over 59 years were at an increased risk. There are some potentially important findings from this study which might influence medical care. These should be examined in the larger International Radiation Study

  3. A Finnic holy word and its subsequent history

    Full Text Available This article concentrates on a specific ancient holy word in Finnish and its subsequent development, hiisi. In the Finnish language region hiisi appears as an element in place names in over 230 villages established by the end of the thirteenth century, and at least a majority of these must have existed since prehistoric times. In Finland as well as in Estonia it is possible to demonstrate an earlier sacral function in places which contain hiisi as a component of their name, partly with the help of archeological discoveries, and partly with the help of oral folk tradition. It is particularly among the earliest settlement areas of Southwest Finland, Satakunta and Häme that hiisi features in the names of sacrificial sites or trees, in other words in the same areas where it features in the names of burial grounds. Names in which the hiisi element precedes a word meaning a lake, pond, or other water formation, occur particularly in the eastern Finnish dialect regions, as well as in the regions of Karelian, Olonets, Lydian, and Vepsian. In addition to its factual meaning of cult place, the Finnish word hiisi has come to denote a supernatural entity both in terms of its reference to a place and in terms of its reference to a being.

  4. Undernutrition, subsequent risk of mortality and civil war in Burundi.

    The paper investigates the effect of child undernutrition on the risk of mortality in Burundi. Using anthropometric data from a longitudinal survey (1998-2007) we find that undernourished children, measured by the height-for-age z-scores (HAZ) in 1998 had a higher probability to die during subsequent years. In order to address the problem of omitted variables correlated with both nutritional status and the risk of mortality, we use the length of exposure to civil war prior to 1998 as a source of exogenous variation in a child's nutritional status. Children exposed to civil war in their area of residence have worse nutritional status. The results indicate that one year of exposure translates into a 0.15 decrease in the HAZ, resulting in a 10% increase in the probability to die. For boys, we find a 0.34 decrease in HAZ per year of exposure, resulting in 25% increase in the probability to die. For girls, the results are statistically not significant at the usual thresholds. We show the robustness of our results and we derive policy conclusion for a nutrition intervention in times of conflict. Copyright © 2011 Elsevier B.V. All rights reserved.

    Cascade phenomenon may lead to catastrophic disasters which extremely imperil the network safety or security in various complex systems such as communication networks, power grids, social networks and so on. In some flow-based networks, the load of failed nodes can be redistributed locally to their neighboring nodes to maximally preserve the traffic oscillations or large-scale cascading failures. However, in such local flow redistribution model, a small set of key nodes attacked subsequently can result in network collapse. Then it is a critical problem to effectively find the set of key nodes in the network. To our best knowledge, this work is the first to study this problem comprehensively. We first introduce the extra capacity for every node to put up with flow fluctuations from neighbors, and two extra capacity distributions including degree based distribution and average distribution are employed. Four heuristic key nodes discovering methods including High-Degree-First (HDF), Low-Degree-First (LDF), Random and Greedy Algorithms (GA) are presented. Extensive simulations are realized in both scale-free networks and random networks. The results show that the greedy algorithm can efficiently find the set of key nodes in both scale-free and random networks. Our work studies network robustness against cascading failures from a very novel perspective, and methods and results are very useful for network robustness evaluations and protections.

    Distinctive encoding is greatly influenced by gist-based processes and has been shown to suffer when highly similar items are presented in close succession. Thus, elucidating the mechanisms underlying how presentation format affects gist processing is essential in determining the factors that influence these encoding processes. The current study utilised multivariate partial least squares (PLS) analysis to identify encoding networks directly associated with retrieval performance in a blocked and intermixed presentation condition. Subsequent memory analysis for successfully encoded items indicated no significant differences between reaction time and retrieval performance and presentation format. Despite no significant behavioural differences, behaviour PLS revealed differences in brain-behaviour correlations and mean condition activity in brain regions associated with gist-based vs. distinctive encoding. Specifically, the intermixed format encouraged more distinctive encoding, showing increased activation of regions associated with strategy use and visual processing (e.g., frontal and visual cortices, respectively). Alternatively, the blocked format exhibited increased gist-based processes, accompanied by increased activity in the right inferior frontal gyrus. Together, results suggest that the sequence that information is presented during encoding affects the degree to which distinctive encoding is engaged. These findings extend our understanding of the Fuzzy Trace Theory and the role of presentation format on encoding processes.

    Full Text Available The use of labour force acquires new aspects in the stages subsequent to the economic and financial crisis in Romania and we would like to present them in this paper. The imbalances caused by the Romanian economy restructuring were visible in the labour market evolution, offering a new dimension to the issue of adapting the labour force to the market requirements, within the regions and their counties. Through this paper, we want to offer an overview of the Romanian labour market, integrating it in the realities of the international labour market. We will thus seek to observe if the labour market responds, and to what extend if so, to the current requirements given by the realities emerged as a consequence of the crisis’ effects. In order to analyse what we had set to, we used the most recent statistical data on the official labour market but, in order to get an even clearer image of the field, we also appealed to data offered by the National Prognosis Commission, indicating the source. Analysing the practical features when taking into consideration the emigration possibility presents a major interest for completing this study, as lately we are witnesses to massive migration, especially of the qualified youth, which leads to a decrease in labour force quality in the country. Also, an analysis of the sectors with significant imbalances between the number of job vacancies and the number of employees may contribute to identifying the current labour market trends.

  9. Association between systemically administered radioisotopes and subsequent malignant disease

    There is a long history recording the association of x radiation and the subsequent development of malignant tumors. For systemically administered isotopes this came into prominence when Martland discovered the association between cancer, particularly of the bone, and ingestion of radioactive isotopes by radium dial painters. This association was amplified by the development of cancer in patients given thorotrast as a contrast medium for diagnostic radiologic examination. Acute leukemia was reported 30 years ago in patients with polycythemia vera treated with 32 P. Acute leukemia also occurs in patients with polycythemia vera treated only with phlebotomy or drugs. A controlled study is now underway to provide a more definite answer to question what is the incidence of acute leukemia in patients with polycythemia vera treated by phlebotomy alone, chlorambucil, or 32 P. 131 I for the treatment of hyperthyroidism probably does not induce cancer, but in the doses used for thyroid cancer there was an increased incidence of neoplasms (12/200 in one study). This was higher than the expected incidence of neoplasms. The doses of radioactive isotopes used currently for diagnostic purposes have not induced cancer, but it is difficult and probably impossible to verify this with absolute certainty

    2017-11-01

    The use of diagnostic medical imaging is becoming increasingly more commonplace in the pediatric setting. However, many medical imaging modalities expose pediatric patients to ionizing radiation, which has been shown to increase the risk of cancer development in later life. This review article provides a comprehensive overview of the available data regarding the risk of cancer development following exposure to ionizing radiation from diagnostic medical imaging. Attention is paid to modalities such as computed tomography scans and fluoroscopic procedures that can expose children to radiation doses orders of magnitude higher than standard diagnostic x-rays. Ongoing studies that seek to more precisely determine the relationship of diagnostic medical radiation in children and subsequent cancer development are discussed, as well as modern strategies to better quantify this risk. Finally, as cardiovascular imaging and intervention contribute substantially to medical radiation exposure, we discuss strategies to enhance radiation safety in these areas.

    Radiation-induced lung disease is a known complication of therapeutic lung irradiation, but the features have not been well described in children. We report the clinical, radiologic and histologic features of interstitial lung disease (ILD) in a 4-year-old child who had previously received lung irradiation as part of successful treatment for metastatic Wilms tumor. Her radiologic abnormalities and clinical symptoms developed in an indolent manner. Clinical improvement gradually occurred with corticosteroid therapy. However, the observed radiologic progression from interstitial and reticulonodular opacities to diffuse cystic lung disease, with subsequent improvement, is striking and has not been previously described in children.

    Of the cases of lung cancer in which radiation therapy was given between 1961 and November 1981, 399 cases for which histological type was confirmed, and irradiated as follows were reviewed. The cases of squamous cell carcinoma and adenocarcinoma irradiated with more than 5,000 rad or more, those of undifferentiated carcinoma irradiated with 3,000 rad or more, and those irradiated pre- and post-operatively with 3,000 rad or more. The actual 5 year survival rate for stages I, II, III and IV were 29.6, 9.3, 7.5 and 1.9% respectively, and the survival rate tended to be better for adenocarcinoma than squamous cell carcinoma at stages I, II and III, but not different at stage IV. There was no difference between large cell, small cell and squamous cell carcinomas. Irradiation with 200 rad every other day or 150 rad daily was better than that with 200 rad, and daily irradiation with 150 rad was used since 1976. The therapy of stage III small cell carcinoma at the age of up to 80 years was improved with the combination of anticancer agents, maintenance therapy and immunotherapy, but these combined therapies were not significantly effective for the cancers with other histological types or at other stages. Although there was no significant difference in statistics for resectable cases, clinically, the results were experienced to be better after resection, and surgery was done in combination as much as possible.

    Therapies administered by mental health nurses, aimed at "curing" gay people of their sexual preference were still in common use in the UK in the 1960s and early 1970s. Some nurses tried to avoid participating in these practices, but many believed that they were helping their patients, as a new book reveals.

    Treatment patterns for metastatic castration-resistant prostate cancer (mCRPC) have changed substantially in the last few years. In trial COU-AA-302 (chemotherapy-naïve men with mCRPC), abiraterone acetate plus prednisone (AA) significantly improved radiographic progression-free survival and overall survival (OS) when compared to placebo plus prednisone (P). This post hoc analysis investigated clinical responses to docetaxel as first subsequent therapy (FST) among patients who progressed following protocol-specified treatment with AA, and characterized subsequent treatment patterns among older (≥75 yr) and younger (AA arm received subsequent treatment with one or more agents approved for mCRPC. Efficacy analysis was performed for patients for whom baseline and at least one post-baseline prostate-specific antigen (PSA) values were available. Baseline and at least one post-baseline PSA values were available for 100 AA patients who received docetaxel as FST. While acknowledging the limitations of post hoc analyses, 40% (40/100) of these patients had an unconfirmed ≥50% PSA decline with first subsequent docetaxel therapy, and 27% (27/100) had a confirmed ≥50% PSA decline. The median docetaxel treatment duration among these 100 patients was 4.2 mo. Docetaxel was the most common FST among older and younger patients from each treatment arm. However, 43% (79/185) of older patients who progressed on AA received no subsequent therapy for mCRPC, compared with 17% (60/361) of younger patients. Patients with mCRPC who progress with AA treatment may still derive benefit from subsequent docetaxel therapy. These data support further assessment of treatment patterns following AA treatment for mCRPC, particularly among older patients. ClinicalTrials.gov NCT00887198. Treatment patterns for advanced prostate cancer have changed substantially in the last few years. This additional analysis provides evidence of clinical benefit for subsequent chemotherapy in men with advanced

    Full Text Available This study investigated the release and proteomic profile of tissue factor microparticles (TFMPs prospectively (up to 6 months following a myocardial infarction (MI in a chronic porcine model to establish their utility in tracking cellular level activities that predict physiologic outcomes. Our animal groups (n = 6 to 8 each consisted of control, noninfarcted (negative control; infarcted only (positive control; and infarcted animals treated with cardiac resynchronization therapy (CRT and a β-blocker (BB (metoprolol succinate. The authors found different protein profiles in TFMPs between the control, infarcted only group, and the CRT + BB treated group with predictive impact on the outward phenotype of pathological remodeling after an MI within and between groups. This novel approach of monitoring cellular level activities by profiling the content of TFMPs has the potential of addressing a shortfall of the current crop of cardiac biomarkers, which is the inability to capture composite molecular changes associated with chronic maladaptive signaling in a spatial and temporal manner.

  17. Proton therapy

    Ideal radiotherapy deposits a large amount of energy in the tumour volume, and none in the surrounding healthy tissues. Proton therapy comes closer to this goal because of a greater concentration of dose, well defined proton ranges and points of energy release which are precisely known - the Bragg peak1. In the past, the development of clinical proton therapy has been hampered by complexity, size, and cost. To be clinically effective, energies of several hundred MeV are required; these were previously unavailable for hospital installations, and pioneering institutions had to work with complex, inadequate equipment originally intended for nuclear physics research. Recently a number of specialist organizations and commercial companies have been working on dedicated systems for proton therapy. One, IBA of Belgium, has equipment for inhouse hospital operation which encompasses a complete therapy centre, delivered as a turnkey package and incorporating a compact, automated, higher energy cyclotron with isocentric gantries. Their system will be installed at Massachusetts General Hospital, Boston. The proton therapy system comprises: - a 235 MeV isochronous cyclotron to deliver beams of up to 1.5 microamps, but with a hardware limitation to restrict the maximum possible dose; - variable energy beam (235 to 70 MeV ) with energy spread and emittance verification; - a beam transport and switching system to connect the exit of the energy selection system to the entrances of a number of gantries and fixed beamlines. Along the beam transport system, the beam characteristics are monitored with non-interceptive multiwire ionization chambers for automatic tuning; - gantries fitted with nozzles and beamline elements for beam control; both beam scattering and beam wobbling techniques are available for shaping the beam;

    Purpose: To evaluate the patterns and timing of initial recurrence in patients with Hodgkin's lymphoma (HL) who subsequently underwent high-dose chemotherapy with autologous stem cell transplantation to enhance our understanding of the natural history of this disease and its modern treatment strategies and to direct approaches to disease surveillance. Methods and Materials: The records of 69 patients with HL who had undergone high-dose chemotherapy with autologous stem cell transplantation in our center between May 1992 and June 2006 were analyzed. The initial diagnosis had been made between April 1982 and January 2005 at a median patient age of 33 years (range, 19-65). The patients were segregated according to the initial stage (Stage I-II vs. III-IV). Results: Early-stage HL patients developed a relapse at a median of 2.1 years (range, 0.5-10.3), with 91% of relapses at the initial disease site, 71% of which (65% overall) were only in previously involved sites. Advanced-stage HL patients developed a relapse at a median of 1.5 years (range, 0.6-10.5), with 97% at the initial site, 71% of which (69% overall) were only in previously involved sites. Single-site relapses occurred in 47% of early- vs. 26% of advanced-stage patients, and extranodal relapses occurred in 12% of early- vs. 31% of advanced-stage patients. Conclusions: Almost all patients with HL who develop relapse and subsequently undergo high-dose chemotherapy with autologous stem cell transplantation initially developed recurrence in previously involved disease sites. Early-stage HL relapses often occurred in single sites, and advanced-stage disease relapses were more likely in multiple and extranodal sites. The interval to recurrence was brief, suggesting that the frequency of screening should be the greatest in the early post-therapy years.

    The objective of this study was to examine the potentiating effects of performing a single sprint-style sled push on subsequent unresisted 20m sprint performance. Randomized crossover design. Following a familiarization session, twenty rugby league players performed maximal unresisted 20m sprints before and 15s, 4, 8 and 12min after a single sled push stimulus loaded with either 75 or 125% body mass. The two sled push conditions were performed in a randomized order over a one-week period. The fastest sprint time recorded before each sled push was compared to that recorded at each time point after to determine the post-activation potentiation (PAP) effect. After the 75% body mass sled push, sprint time was 0.26±1.03% slower at the 15s time point (effect size [ES]=0.07) but faster at the 4 (-0.95±2.00%; ES=-0.22), 8 (-1.80±1.43%; ES=-0.42) and 12 (-1.54±1.54%; ES=-0.36)min time points. Sprint time was slower at all the time points after the 125% body mass sled (1.36±2.36%-2.59±2.90%; ESs=0.34-0.64). Twenty-meter sprint performance is potentiated 4-12min following a sled push loaded with 75% body mass while it is impaired after a 125% body mass sled. These results are of great importance for coaches seeking to potentiate sprint performance with the sled push exercise. Copyright © 2017 Sports Medicine Australia. Published by Elsevier Ltd.

    Many states have enacted laws to improve school nutrition. We tested whether stronger state nutrition laws are associated with subsequently decreased obesity. We conducted a retrospective national multi-year panel data study (analyzed 2014-2016 at the Children's Hospital of Philadelphia). The predictors were 2010 laws regarding 9 nutrition categories from the Classification of Laws Associated with School Students, which grades the strength of state laws (none, weak, or strong). The outcome was weight status (healthy weight, overweight, or obese) in elementary, middle, and high school from the 2011/2012 National Survey of Children's Health. We tested the association between the strength of laws and weight using multinomial logistic regression. To further evaluate our main results, we conducted state-level longitudinal analyses testing the association between competitive food and beverage laws on the change in obesity from 2003-2011. In main analyses of 40,177 children ages 10-17years, we found strong state laws restricting the sale of competitive food and beverages in elementary school (OR: 0.68; 95% CI: 0.48, 0.96) and strong advertising laws across all grades (OR: 0.63; 95% CI: 0.46, 0.86) were associated with reduced odds of obesity. In longitudinal analyses, states with strong competitive food and beverage laws from 2003-2010 had small but significant decreases in obesity, compared to states with no laws. Although further research is needed to determine the causal effect of these laws, this study suggests that strong state laws limiting the sale and advertising of unhealthy foods and beverages in schools are associated with decreased obesity rates.

    Full Text Available To examine the association between a woman's birth weight and her subsequent fecundability.In this prospective cohort study, we included 2,773 Danish pregnancy planners enrolled in the internet-based cohort study "Snart-Gravid", conducted during 2007-2012. Participants were 18-40 years old at study entry, attempting to conceive, and were not receiving fertility treatment. Data on weight at birth were obtained from the Danish Medical Birth Registry and categorized as <2,500 grams, 2,500-2,999 grams, 3,000-3,999 grams, and ≥ 4,000 grams. In additional analyses, birth weight was categorized according to z-scores for each gestational week at birth. Time-to-pregnancy measured in cycles was used to compute fecundability ratios (FR and 95% confidence intervals (CI, using a proportional probabilities regression model.Relative to women with a birth weight of 3,000-3,999 grams, FRs adjusted for gestational age, year of birth, and maternal socio-demographic and medical factors were 0.99 (95% CI: 0.73;1.34, 0.99 (95% CI: 0.87;1.12, and 1.08 (95% CI: 0.94;1.24 for birth weight <2,500 grams, 2,500-2,999 grams, and ≥ 4,000 grams, respectively. Estimates remained unchanged after further adjustment for markers of the participant's mother's fecundability. We obtained similar results when we restricted to women who were born at term, and to women who had attempted to conceive for a maximum of 6 cycles before study entry. Results remained similar when we estimated FRs according to z-scores of birth weight.Our results indicate that birth weight appears not to be an important determinant of fecundability.

  2. Melatonin Secretion during a Short Nap Fosters Subsequent Feedback Learning

    Full Text Available Sleep helps to protect and renew hippocampus-dependent declarative learning. Less is known about forms of learning that mainly engage the dopaminergic reward system. Animal studies showed that exogenous melatonin modulates the responses of the dopaminergic reward system and acts as a neuroprotectant promoting memory. In humans, melatonin is mainly secreted in darkness during evening hours supporting sleep. In this study, we investigate the effects of a short period of daytime sleep (nap and endogenous melatonin on reward learning. Twenty-seven healthy, adult students took part in an experiment, either taking a 90-min afternoon nap or watching videos (within-subject design. Before and after the sleep vs. wake interval, saliva melatonin levels and reward learning were measured, and in the nap condition, a polysomnogram was obtained. Reward learning was assessed using a two-alternative probabilistic reinforcement-learning task. Sleep itself and subjective arousal or valence had no significant effects on reward learning. However, this study showed for the first time that an afternoon nap can elicit a small but significant melatonin response in about 41% of the participants and that the magnitude of the melatonin response predicts subsequent reward learning. Only in melatonin responders did a short nap improve reward learning. The difference between melatonin-responders and non-responders occurred very early during learning indicating that melatonin might have improved working memory rather than reward learning. Future studies should use paradigms differentiating working memory and reward learning to clarify which aspect of human feedback learning might profit from melatonin.

    To determine outcomes after removal of two synthetic mid-urethral slings (MUS) at a tertiary care center. Following IRB approval, a retrospective chart review of non-neurogenic, symptomatic women requiring re-operation after ≥2 MUS was performed. Data reviewed by a third party included: demographics, prior anti-incontinence surgery, complications, pelvic/urinary symptoms, subsequent investigations, surgical repair and outcomes (including UDI-6/IIQ-7 questionnaires) at a minimum 6 months follow-up. Cure was defined as being continent, no dyspareunia, and no additional surgical therapy. Between 2007 and 2014, 21 women met the inclusion criteria. Mean age was 57 years (range: 40-82) and mean follow-up was 30.2 months (range: 6-78). The majority of patients presented with one or more symptoms of voiding dysfunction (95%), urinary incontinence (86%), irritative voiding symptoms (62%), dyspareunia (57%), recurrent urinary tract infections (UTIs) (29%), vaginal extrusion (20%) and erosion involving the urinary tract (5%). Patients had a mean of 2 prior anti-incontinence procedures (range 2-3). Over two-thirds had a combination of retropubic and transobturator MUS. Mean number of pre-operative investigations was 3.5 (1-6) including voiding cystourethrogram, cystoscopy and urodynamics. Two patients had complete remission, 14 partial remission, and five failed. Mean postoperative total UDI-6 and IIQ-7 scores at last clinic visit were 10 (range: 0-16/SD 4.1) and 11 (range: 0-28/SD 10.3), respectively. The management of women with suboptimal outcomes following two synthetic MUS from transvaginal excision results in modest symptomatic improvement but low permanent complete remission and frequent need for additional therapies. © 2017 John Wiley & Sons Australia, Ltd.

Physicists played a major role in proposing the potential applications in radiotherapy as well as in the development of particle therapy. A brief review of the current status of particle radiotherapy with some historical perspective is presented and specific contributions made by physicists will be pointed out wherever appropriate. The rationale of using particles in cancer treatment is to reduce the treatment volume to the target volume by using precise dose distributions in three dimensions by using particles such as protons and to improve the differential effects on tumors compared to normal tissues by using high-LET radiations such as neutrons. Pions and heavy ions combine the above two characteristics.

    1975-01-01

    To determine the long-term effects of therapeutic pulmonary irradiation and treatment with actinomycin D during a period of lung growth, 12 patients treated for Wilms' tumor metastatic to the lung and 8 patients treated for Wilms' tumor with no evidence of pulmonary metastases were studied 7 to 14 years after their initial tumor therapy. All patients had received irradiation to the tumor bed and treatment with actinomycin D. Group 1 had received a single course of bilateral pulmonary irradiation; group 2 had received additional pulmonary irradiation and/or thoracic surgery; group 3 had received no therapeutic irradiation directed primarily to the chest. Total lung capacity (TLC) averaged 71 percent of predicted value in group 1, 58 percent in group 2, and 94 percent in group 3. Diffusing capacity in groups 1 and 2 was reduced to the same extent as lung volume. Quasi-static pressure-volume relationships, studied in three of six patients in group 1, were within the normal range when lung volume was expressed as percentage of observed TLC. Airway resistance, evaluated by spirometry, maximum expiratory flow-volume curves, and resistance of the total respiratory system, was normal or reduced. The data support the hypothesis that therapeutic irradiation during a period of lung growth primarily affects the lung parenchyma and produces a decrease in subsequent size of both the lung and chest wall. No effect of actinomycin D alone upon the lung could be demonstrated

    In the present study, we tested the hypothesis that calories consumed at a prior meal (lunch) may impair glycemic control after a subsequent meal (supper) even if the pre-supper glucose did not differ regardless of the size of the lunch meal. Nine subjects with Type 1 diabetes using continuous subcutaneous (s.c.) insulin infusion (CSII) therapy were studied on two separate days. Lunch (1200 h) was randomly assigned as 25% or 50% of the usual daily intake on alternate study days. The CSII was stopped at 1000 h on the day of the study and glucose was controlled until supper by adjusting the rate of intravenous (i.v.) insulin based on glucose measurements every 15 min. The CSII was restarted 1 h before supper and i.v. insulin discontinued 15 min before the first bite of supper. An identical supper meal and pre-supper s.c. bolus of short-acting insulin were administered on both visits. Pre-supper glycemia was nearly identical on each of the two study days. However, the post-supper glucose area under the curve was 27.5% greater on the day of the antecedent large lunch compared with the small lunch (P = 0.0039). For optimal postprandial glucose control, people with Type 1 diabetes may need to consider not only anticipated meal calories, but also prior food intake, a practice not commonly recommended based on currently used insulin dosing algorithms.

Here, we present a rare case of lung adenocarcinoma harboring EGFR activating mutation and ALK overexpression. During the EGFR-tyrosine kinase inhibitors treatment, next-generation sequencing revealed phosphatidylinositol 3-kinase/Akt/mammalian target of rapamycin pathway amplifications in tumor specimen and subsequent T790M mutation via plasma circulating tumor DNA. In conclusion, this case illustrates the existence of concomitant resistance mechanisms and demonstrates that circulating tumor DNA can reflect tumor heterogeneity.

    Purpose: To analyze the value of Transrectal ultrasound(TRUS), Color flow doppler(CFD) and Prostate specific antigen(PSA) in identifying residual disease in the prostate status post external beam radiation therapy and to determine the value of this pathologic information in predicting subsequent disease progression. Materials and Methods: As part of four prospective protocols, 146 patients had scheduled TRUS guided prostate biopsies 6-25 months status post radiation therapy. The stage distribution was: 13% T1, 51% T2, and 36% T3/T4. Fifty six percent had neo-adjuvant hormones. Conformal photon or mixed neutron/photon irradiation was given to a median 2 Gy/fraction equivalent dose of 77 Gy(range 74 to 84 Gy). Following treatment, patients were assessed by digital rectal exam (DRE), PSA and TRUS guided biopsies at 6, 12 and/or 18 months. The ultrasound and CFD results were scored as normal, suspicious or abnormal. Sextant biopsies were obtained as well as ultrasound guided biopsies from any abnormal ultrasound or doppler area. The biopsies, all read by one pathologist (DG), were graded as negative, marked, moderate, minimal therapeutic effect or positive. The median followup post radiation therapy was 33.6 months and post biopsy was 25.3 months. Comparisons were done by Kappa index with corresponding 95% CI, chi square and Fisher's exact tests. Results: Twenty-eight patients had biopsies at both six and 12-18 months. Overall 35% of patients had all negative cores, 30% had at least one core showing a marked therapeutic effect, and 35% had at least one core showing moderate or minimal therapeutic effect or were positive. Although CFD correlated with a positive biopsy in 9% and a suspicious doppler identified cancer in 15% of cases, an abnormal TRUS identified cancer in 29.5% biopsies ((49(166))). However, a serum PSA >1.5ng/ml at the time of biopsy predicted 61% of positive biopsies ((23(38))). A negative biopsy was associated with low stage (≤T2c, p=0.001), low pre

    Full Text Available Four crossbred cows with mummified fetus were utilized for the study. The cows weresubjected togynecologicalexamination and based on the findings the cases were diagnosed asmummified fetus. The cows were treated with 2 mg estradiol valerate and 500 μg cloprostenoland were examined every 12 hr after 24 hr of the treatment for cervical dilatation and othersigns related to fetal expulsion. The time duration between treatment and starting of cervicaldilatation ranged from 48 to 58h (53.00 ± 2.08 hr. Complete dilatation of cervix was observedafter 70.00 ± 2.94 hr post treatment (Range = 64-76 hr. The mean fetalcrown-rump length(CRL was 31.5 cm, which ranged from 27.5 to 38 cm. The number of cotyledons in pregnanthorn also showed wide variation (Range 24-38 numbers with mean ± SE of 30.3 ± 3.07numbers. In the placenta of three animals irregular shaped large adventitious cotyledons wereobserved in the inter-cotyledonary areas. Out of the four animals treated, three animals wereconceived within three estrous cycles and one animal had cystic ovary in the next cycle and wasnot conceived even after four cycles. It was concluded that the estradiolandprostaglandin F2α(PGF2αcombinationtherapy was effective for expulsion of mummified fetus in crossbred cowswithout affecting much on future fertility.

    The authors describe Gestalt Therapy. They retrace its fundamental theoretical axes. These are psychoanalysis, character analysis, the german Gestalt theory of perception, existentialism, and the Orient. Some principal concepts are then elaborated more fully such as the cycle of awareness, desensitization, excitation anxiety and the five defense mechanisms: retroflection, introjection, projection, deflection, and confluence. The nature and goals of the therapeutic process are also described before the presentation of some techniques specific to this approach such as enactment and role playing. Finally, certain basic Gestalt rules, which aim at facilitating and intensifying the communication process among group members, are enunciated.

    The radiation oncologist encounters the critically ill immunosuppressed patient in four settings. First, the newly diagnosed cancer patient presents for initial evaluation and treatment, with immunosuppression from the cancer itself, malnutrition, concomitant infectious disease, prior drug or alcohol abuse or other medical problems. Second, the previously treated cancer patient presents with metastatic or recurrent primary cancer causing local symptoms. Immune dysfunction in this setting may be due to prior chemotherapy and/or radiation as well as any of the original factors. Third, the patient previously treated with radiation presents with a life-threatening problem possibly due to complications of prior therapy. In this setting, the radiation oncologist is asked to evaluate the clinical problem and to suggest whether radiation might be causing part or all of the problem and what can be done to treat these sequelae of radiation. Fourth, the patient with a benign diagnosis (not cancer) is seen with a problem potentially emeliorated by radiation (e.g., kidney transplant rejection, preparation for transplant, or intractable rheumatoid arthritis). This chapter reviews these four issues and presents clinical and radiobiologic principles on which recommendations for therapy are based

    2015-06-01

    The treatment of multiple myeloma has evolved significantly over the past 2 decades due to the use of high-dose chemotherapy and autologous stem cell transplantation, and the subsequent introduction of the immunomodulatory agents (thalidomide and lenalidomide) and the proteasome inhibitor (bortezomib). The median overall survival of multiple myeloma patients has increased significantly with patients younger than age 50 years experiencing a 10-year survival rate of around 40%. However, despite the increased effectiveness of the first-line agents, the majority of patients will eventually relapse and become drug resistant. Promising novel therapies have recently emerged and are being used to treat relapsed and refractory patients. This review will cover the clinical data regarding these emergent therapies that include new generation of proteasome inhibitors (carfilzomib, ixazomib, oprozomib, and marizomib), immunomodulatory drugs (pomalidomide), monoclonal antibodies (elotuzumab and daratumumab), signal transduction modulator (perifosine), and histone deacetylase inhibitors (vorinostat and panobinostat).

    Using a questionnaire the EANM Task Group Radionuclide Therapy in 1993 collected data on the current practice of radionuclide therapy in European countries. Subsequently, at the request of the EANM Executive Committee, the EANM Radionuclide Therapy Committee has made an inventory of the distribution of facilities for radionuclide therapy and undertaken an assessment of the total number of patients treated throughout Europe and of the types of treatment provides, with the aim of supporting the development of policy to adjust the available capacity to the needs by the year 2000. For this purpose, a second, more detailed questionnaire was sent out the members and national advisors of the Committee (see below), who gathered the data for each country that was a member of the EANM at the time. It is concluded that a wide bariation in therapy practice exists across Europe, particularly in the utilisation of radionuclide therapy, the requirement and availability of proper isolation facilities and the background training of those undertaking therapy. More uniform guidelines and legislation are required, although changes in legislation may have a significant impact in some countries. Although there is wide variation in the therapies used in each country, one the whole it appears that there is an underutilisation of nuclear medicine as a therapeutic modality. A rapidly increasing role may be expected, in particular for oncological indications requiring high-dose radionuclide treatment. Therefore there is an urgent need for a greater number of isolation beds in dedicated centers throughout Europe

    2008-01-01

    Purpose: Subsequent malignant neoplasms (SMNs) are a dominant cause of morbidity and mortality in children treated for Hodgkin's disease (HD). We evaluated select demographic and therapeutic factors associated with SMNs, specifically gender and radiation dose. Methods and Materials: A total of 930 children treated for HD at five institutions between 1960 and 1990 were studied. Mean age at diagnosis was 13.6 years, and mean follow-up was 16.8 years (maximum, 39.4 years). Treatment included radiation alone (43%), chemotherapy alone (9%), or both (48%). Results: We found that SMNs occurred in 102 (11%) patients, with a 25-year actuarial rate of 19%. With 15,154 patient years of follow-up, only 7.18 cancers were expected (standardized incidence ratio [SIR] = 14.2; absolute excess risk [AER] = 63 cases/10,000 years). The SIR for female subjects, 19.93, was significantly greater than for males, 8.41 (p < 0.0001). After excluding breast cancer, the SIR for female patients was 15.4, still significantly greater than for male patients (p = 0.0012). Increasing radiation dose was associated with an increasing SIR (p = 0.0085). On univariate analysis, an increased risk was associated with female gender, increasing radiation dose, and age at treatment (12-16 years). Using logistic regression, mantle radiation dose increased risk, and this was 2.5-fold for female patients treated with more than 35 Gy primarily because of breast cancer. Conclusions: Survivors of childhood HD are at risk for SMNs, and this risk is greater for female individuals even after accounting for breast cancer. Although SMNs occur in the absence of radiation therapy, the risk increases with RT dose

    Recently, pulmonary rehabilitation program is widely considered one of the most effective and evidence-based treatment for not only chronic obstructive pulmonary disease (COPD) but many clinical situations including neuro-muscular disease, post-operative status and weaning period from the ventilator, etc. The essential components of a pulmonary rehabilitation program are team assessment, patient training, psycho-social intervention, exercise, and follow-up. In 2003, Japanese medical societies (J. Thoracic Society, J. Pul. Rehabilitation Society and J. Physiotherapist Society) made a new guideline for pulmonary rehabilitation, especially how to aproach the execise training. As for the duration after surgical operation, airway cleaning is the important technique to prevent post-operative complications including pneumonia. Postural dranage technique is well known for such condition, at the same time, several instruments (flutter vulve, positive expiratory mask, high frequecy oscillation, etc) were also used for the patient to expectrate airway mucus easier. Lung transplantation is a new method of treatment for the critically-ill patients with chronic respiratoy failure. Several techniques of physical therapy are must be needed before and after lung transplantation to prevent both pulmonary infection and osteoporosis.

    We identified 10 patients with disseminated Mycobacterium chimaera infections subsequent to open-heart surgery at three European Hospitals. Infections originated from the heater-cooler unit of the heart-lung machine. Here we describe clinical aspects and treatment course of this novel clinical entity. Interdisciplinary care and follow-up of all patients was documented by the study team. Patients' characteristics, clinical manifestations, microbiological findings, and therapeutic measures including surgical reinterventions were reviewed and treatment outcomes are described. The 10 patients comprise a 1-year-old child and nine adults with a median age of 61 years (range 36-76 years). The median duration from cardiac surgery to diagnosis was 21 (range 5-40) months. All patients had prosthetic material-associated infections with either prosthetic valve endocarditis, aortic graft infection, myocarditis, or infection of the prosthetic material following banding of the pulmonary artery. Extracardiac manifestations preceded cardiovascular disease in some cases. Despite targeted antimicrobial therapy, M. chimaera infection required cardiosurgical reinterventions in eight patients. Six out of 10 patients experienced breakthrough infections, of which four were fatal. Three patients are in a post-treatment monitoring period. Healthcare-associated infections due to M. chimaera occurred in patients subsequent to cardiac surgery with extracorporeal circulation and implantation of prosthetic material. Infections became clinically apparent after a time lag of months to years. Mycobacterium chimaera infections are easily missed by routine bacterial diagnostics and outcome is poor despite long-term antimycobacterial therapy, probably because biofilm formation hinders eradication of pathogens.

  16. Radiomic signature of infiltration in peritumoral edema predicts subsequent recurrence in glioblastoma: implications for personalized radiotherapy planning.

    Standard surgical resection of glioblastoma, mainly guided by the enhancement on postcontrast T1-weighted magnetic resonance imaging (MRI), disregards infiltrating tumor within the peritumoral edema region (ED). Subsequent radiotherapy typically delivers uniform radiation to peritumoral FLAIR-hyperintense regions, without attempting to target areas likely to be infiltrated more heavily. Noninvasive in vivo delineation of the areas of tumor infiltration and prediction of early recurrence in peritumoral ED could assist in targeted intensification of local therapies, thereby potentially delaying recurrence and prolonging survival. This paper presents a method for estimating peritumoral edema infiltration using radiomic signatures determined via machine learning methods, and tests it on 90 patients with de novo glioblastoma. The generalizability of the proposed predictive model was evaluated via cross-validation in a discovery cohort ([Formula: see text]) and was subsequently evaluated in a replication cohort ([Formula: see text]). Spatial maps representing the likelihood of tumor infiltration and future early recurrence were compared with regions of recurrence on postresection follow-up studies with pathology confirmation. The cross-validated accuracy of our predictive infiltration model on the discovery and replication cohorts was 87.51% (odds ratio = 10.22, sensitivity = 80.65, and specificity = 87.63) and 89.54% (odds ratio = 13.66, sensitivity = 97.06, and specificity = 76.73), respectively. The radiomic signature of the recurrent tumor region revealed higher vascularity and cellularity when compared with the nonrecurrent region. The proposed model shows evidence that multiparametric pattern analysis from clinical MRI sequences can assist in in vivo estimation of the spatial extent and pattern of tumor recurrence in peritumoral edema, which may guide supratotal resection and/or intensification of postoperative radiation therapy.

  17. Antimetabolites: Established cancer therapy

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Cell death has been divided into two main types: programmed cell death, in which the cell plays an active role, and passive (necrotic cell death. Senescence arrest, accelerated senescence and differentiation are also responses that can be induced in response to DNA-damaging agents. Apoptosis may occur as a primary event following chemotherapy, in which genes that regulate apoptosis will influence the outcome of therapy or, alternatively, as an event secondary to the induction of lethal damage that involves the subsequent processing of cellular damage. The particular type of response induced is highly dependent on the agent and dose employed, the type of DNA damage induced as well as the genetic and cellular phenotypes. It has been proposed that apoptosis may play a lesser role in tumor response to radiation in comparison with the induction of cell death through mitotic catastrophe or a senescence-like irreversible growth arrest. However, in comparison with the induction of apoptosis, there is a lack of as much definitive information on other cell death processes that occur in cancer cells in response to chemotherapeutic agents, including antimetabolites. This article reviews what is known about these processes at the present time in response to experimental or clinically used agents that are analogs of 5-fluorouracil, cytidine or purines, hydroxyurea, or that belong to the family of folate antagonists.

    Full Text Available The role of cutaneous human papillomavirus (HPV infection in the development of subsequent cutaneous squamous cell carcinoma (SCC is unknown. Pathologically confirmed cases of SCC (n=150 enrolled in a previously conducted case-control study were included in a retrospective cohort study to examine the association of cutaneous HPV at the time of SCC diagnosis with the risk of subsequent SCC development. Data on HPV seropositivity, HPV DNA in eyebrow hairs (EB and SCC tumors were available from the parent study. Incidence of subsequent SCC was estimated using person-years of follow up. Cox Proportional Hazards ratios were estimated to evaluate the associations of both, HPV seropositivity and HPV DNA positivity with subsequent SCC. The five year cumulative incidence of subsequent SCC was 72%. Seropositivity to cutaneous HPV was not associated with the risk of subsequent SCC (HR = 0.83, 95% CI = 0.41–1.67. Any beta HPV infection in EB was associated with reduced risk (HR = 0.30, 95% CI = 0.11–0.78 of subsequent SCC among cases who were positive for beta HPV DNA in tumor tissue. Infection with beta HPV type 2 (HR = 0.32, 95% CI = 0.12–0.86 in EB was associated with reduced risk of subsequent SCC among HPV DNA positive SCCs. In conclusion, beta HPV infection was inversely associated with the risk of subsequent SCC.

    2008-03-01

    Cartilage defects of the upper ankle joint reflect the problem that great force is transmitted and balanced out over a relatively small surface area. As a pathophysiological factor, cartilage-bone contusions play a significant role in the development of cartilage defects of the upper ankle joint. Physiotherapeutic procedures belong to the standard procedures of conservative therapy. The use and selection of the type of therapy is based on empirical considerations and experience and investigations on effectiveness of particular therapies are relatively rare. At present a symptom-oriented therapy of cartilage defects of the upper ankle joint seems to be the most sensible approach. It can be assumed that it makes sense that the symptomatic treatment of cartilage defects or initial stages of arthritis also includes the subsequent symptoms of pain, irritated condition and limited function. This leads to starting points for physiotherapy with respect to pain therapy, optimisation of pressure relationships, avoidance of pressure points, improvement of diffusion and pressure release. In addition to the differential physiotherapeutic findings, the determination of a curative, preventive or rehabilitative procedure is especially important. In physical therapy special importance is placed on a scheduled serial application corresponding to the findings, employing the necessary methods, such as physiotherapy, sport therapy, medical mechanics, manual therapy, massage, electrotherapy and warmth therapy. From this the findings-related therapy is proposed as a practical therapy concept: locomotive apparatus pain therapy, optimisation of pressure relationships, improvement of diffusion and decongestion therapy. Therapy options have been selected base on the current literature and are summarised in tabular form. The art of symptomatic therapy of cartilage defects of the upper ankle joint does not lie in the multitude of sometimes speculative procedures, but in the targeted selection

    Full Text Available A permutation π is said to be τ-avoiding if it does not contain any subsequence having all the same pairwise comparisons as τ. This paper concerns the characterization and enumeration of permutations which avoid a set F j of subsequences increasing both in number and in length at the same time. Let F j be the set of subsequences of the form σ(j+1(j+2, σ being any permutation on {1,...,j}. For j=1 the only subsequence in F 1 is 123 and the 123-avoiding permutations are enumerated by the Catalan numbers; for j=2 the subsequences in F 2 are 1234 2134 and the (1234,2134 avoiding permutations are enumerated by the Schröder numbers; for each other value of j greater than 2 the subsequences in F j are j! and their length is (j+2 the permutations avoiding these j! subsequences are enumerated by a number sequence {a n } such that C n ≤ a n ≤ n!, C n being the n th Catalan number. For each j we determine the generating function of permutations avoiding the subsequences in F j according to the length, to the number of left minima and of non-inversions.

  9. Sub-sequence Factorization-an Effective Approach for Projective Reconstruction under Occlusion

    Institute of Scientific and Technical Information of China (English)

    LU Le; HU Zhanyi

    2001-01-01

    Projective reconstruction is a key step for 3D metric reconstruction from a sequence of images captured by an uncalibrated camera. Due to its inherent robustness, the factorization method is widely used in literatures. However, the main shortcoming of the standard factorization method is that it requires the corresponding points to appear across ALL the images. When large changes of view angles occur in the image sequence, or the scene is easy to be self-occluded, nearly it will be very difficult to have some corresponding points visible across all the images. But it is much easier for only several images to have enough correspondences required by factorization method. These images are called as a subsequence in the whole image set. In this paper,a sub-sequence factorization method is proposed to cope with the problem. The basic principle of the sub-sequence factorization method is to divide a long image sequence into several short subsequences according to its spatial continuity, and the standard factorization method is employed for each subsequence.Then, a novel alignment process is invoked to transform different reconstructions under different subsequences into one reference coordinates system. It is more practical as it only demands that there are enough correspondences in each subsequence, not the whole sequence. The proposed sub-sequence factorization method preserves the robustness aspect embedded in the standard factorization method. The experiments on synthetic and real images validate our proposed new method.

    2013-01-01

    This article details the evaluation of a clinical services program for teen mothers in the District of Columbia. The program's primary objectives are to prevent unintended subsequent pregnancy and to promote contraceptive utilization. We calculated contraceptive utilization at 6, 12, 18, and 24 months after delivery, as well as occurrence of subsequent pregnancy and birth. Nearly seven in ten (69.5%) teen mothers used contraception at 24 months after delivery, and 57.1% of contraceptive users elected long-acting reversible contraception. In the 24-month follow-up period, 19.3% experienced at least one subsequent pregnancy and 8.0% experienced a subsequent birth. These results suggest that an integrated clinical services model may contribute to sustained contraceptive use and may prove beneficial in preventing subsequent teen pregnancy and birth.

  14. An IP Framework for the Crew Pairing Problem Using Subsequence Generation

    DEFF Research Database (Denmark)

    Rasmussen, Matias Sevel; Lusby, Richard Martin; Ryan, David

    In this paper we consider an important problem for the airline industry. The widely studied crew pairing problem is typically formulated as a set partitioning problem and solved using the branch-and-price methodology. Here we develop a new integer programming framework, based on the concept...... of subsequence generation, for solving the set partitioning formulation. In subsequence generation one restricts the number of permitted subsequent flights, that a crew member can turn to after completing any particular flight. By restricting the number of subsequences, the number of pairings in the problem...... decreases. The aim is then to dynamically add attractive subsequences to the problem, thereby increasing the number of possible pairings and improving the solution quality. Encouraging results are obtained on 19 real-life instances supplied by Air New Zealand and show that the described methodology...

    Intravenous enzyme replacement therapy is a first-line therapy for Gaucher disease type 1, and substrate reduction therapy represents an oral treatment alternative. Both enzyme replacement therapy and substrate reduction therapy are generally used as monotherapies in Gaucher disease. However, one randomized study and several case reports have described combination therapy over short time periods. We report two female Gaucher disease type 1 patients of mainly Anglo-Saxon descent, where combined enzyme replacement therapy and miglustat substrate reduction therapy were administered to overcome refractory clinical symptoms. The first patient was diagnosed at age 17 and developed Gaucher disease-related bone manifestations that worsened despite starting imiglucerase enzyme replacement therapy. After switching to miglustat substrate reduction therapy, her bone symptoms improved, but she developed tremors and eventually switched back to enzyme replacement therapy. Miglustat was later recommenced in combination with ongoing enzyme replacement therapy due to continued bone pain, and her bone symptoms improved along with maintained visceral manifestations. Enzyme replacement therapy was subsequently tapered off and the patient has since been successfully maintained on miglustat. The second patient was diagnosed aged 3, and commenced imiglucerase enzyme replacement therapy aged 15. After 9 years on enzyme replacement therapy she switched to miglustat substrate reduction therapy and her core symptoms were maintained/stable for 3 years. Imiglucerase enzyme replacement therapy was later added as a boost to therapy and her symptoms were subsequently maintained over a 2.3-year period. However, miglustat was discontinued due to her relocation, necessitating an increase in enzyme replacement therapy dose. Overall, both patients benefited from combination therapy. While the majority of Gaucher disease type 1 patients will not need treatment with both substrate reduction therapy

    A body of epidemiological studies has examined football injuries and associated risk factors among collegiate athletes. However, few existing studies specifically analyzed injury risk in terms of initial or subsequent injuries. To determine athlete-exposures (AEs) and rates of initial and subsequent injury among collegiate football athletes. Descriptive epidemiological study. Injury and exposure data collected from collegiate football players from two Division I universities (2007-2011) were analyzed. Rate of initial injury was calculated as the number of initial injuries divided by the total number of AEs for initial injuries, while the rate for subsequent injury was calculated as the number of subsequent injuries divided by the total number of AEs for subsequent injury. Poisson regression was used to determine injury rate ratio (subsequent vs initial injury), with adjustment for other covariates. The total AEs during the study period were 67,564, resulting in an overall injury rate of 35.2 per 10,000 AEs. Rates for initial and subsequent injuries were 31.7 and 45.3 per 10,000 AEs, respectively, with a rate ratio (RR) of 1.4 for rate of subsequent injury vs rate of initial injury (95% CI, 1.1-1.9). Rate of injury appeared to increase with each successive injury. RR during games was 1.8 (95% CI, 1.1-3.0). The rate of subsequent injuries to the head, neck, and face was 10.9 per 10,000 AEs, nearly double the rate of initial injuries to the same sites (RR = 2.0; 95% CI, 1.1-3.5). For wide receivers, the rate of subsequent injuries was 2.2 times the rate of initial injuries (95% CI, 1.3-3.8), and for defensive linemen, the rate of subsequent injuries was 2.1 times the rate of initial injuries (95% CI, 1.1-3.9). The method used in this study allows for a more accurate determination of injury risk among football players who have already been injured at least once. Further research is warranted to better identify which specific factors contribute to this increased risk

    Yun, Richard J; Krystal, John H; Mathalon, Daniel H

    2010-03-01

    The human working memory system provides an experimentally useful model for examination of neural overload effects on subsequent functioning of the overloaded system. This study employed functional magnetic resonance imaging in conjunction with a parametric working memory task to characterize the behavioral and neural effects of cognitive overload on subsequent cognitive performance, with particular attention to cognitive-limbic interactions. Overloading the working memory system was associated with varying degrees of subsequent decline in performance accuracy and reduced activation of brain regions central to both task performance and suppression of negative affect. The degree of performance decline was independently predicted by three separate factors operating during the overload condition: the degree of task failure, the degree of amygdala activation, and the degree of inverse coupling between the amygdala and dorsolateral prefrontal cortex. These findings suggest that vulnerability to overload effects in cognitive functioning may be mediated by reduced amygdala suppression and subsequent amygdala-prefrontal interaction.

    Purpose: To determine the effect of prostate cancer therapy (surgery or external beam irradiation, or both or none) on the actuarial incidence of subsequent bladder cancer. Methods and Materials: The Surveillance, Epidemiology, and End Results registry from 1973 to 2005 was analyzed. Treatment was stratified as radiotherapy, surgery, both surgery and adjuvant radiation, and neither modality. Brachytherapy was excluded. Results: In all, 555,337 prostate carcinoma patients were identified; 124,141 patients were irradiated; 235,341 patients were treated surgically; 32,744 patients had both surgery and radiation; and 163,111 patients received neither modality. Bladder cancers were diagnosed in: 1,836 (1.48%) men who were irradiated (mean age, 69.4 years), 2,753 (1.09%) men who were treated surgically (mean age, 66.9 years); 683 (2.09%) men who received both modalities (mean age, 67.4 years), and 1,603 (0.98%) men who were treated with neither modality (mean age, 71.8 years). In each treatment cohort, Kaplan-Meier analyses showed that increasing age (by decade) was a significant predictor of developing bladder cancer (p < 0.0001). Incidence of bladder cancer was significantly different for either radiation or surgery alone versus no treatment, radiation versus surgery alone, and both surgery and radiation versus either modality alone (p < 0.0001). On multivariate analysis, age and irradiation were highly significant predictors of being diagnosed with bladder cancer. Conclusions: Following prostate cancer, increasing age and irradiation were highly significant predictors of being diagnosed with bladder cancer. While use of radiation increased the risk of bladder cancer compared to surgery alone or no treatment, the overall incidence of subsequent bladder cancer remained low. Routine bladder cancer surveillance is not warranted.

    A blinded, negative controlled, randomized intervention study was undertaken to test the hypothesis that addition of meloxicam, a nonsteroidal anti-inflammatory drug, to antimicrobial treatment of mild to moderate clinical mastitis would improve fertility and reduce the risk of removal from the herd. Cows (n=509) from 61 herds in 8 regions (sites) in 6 European countries were enrolled. Following herd-owner diagnosis of mild to moderate clinical mastitis within the first 120 d of lactation in a single gland, the rectal temperature, milk appearance, and California Mastitis Test score were assessed. Cows were randomly assigned within each site to be treated either with meloxicam or a placebo (control). All cows were additionally treated with 1 to 4 intramammary infusions of cephalexin and kanamycin at 24-h intervals. Prior to treatment and at 14 and 21 d posttreatment, milk samples were collected for bacteriology and somatic cell count. Cows were bred by artificial insemination and pregnancy status was subsequently defined. General estimating equations were used to determine the effect of treatment (meloxicam versus control) on bacteriological cure, somatic cell count, the probability of being inseminated by 21 d after the voluntary waiting period, the probability of conception to first artificial insemination, the number of artificial insemination/conception, the probability of pregnancy by 120 or 200 d postcalving, and the risk of removal by 300 d after treatment. Cox's proportional hazards models were used to test the effect of treatment on the calving to first insemination and calving to conception intervals. Groups did not differ in terms of age, clot score, California Mastitis Test score, rectal temperature, number of antimicrobial treatments given or bacteria present at the time of enrollment, but cows treated with meloxicam had greater days in milk at enrollment. Cows treated with meloxicam had a higher bacteriological cure proportion than those treated with

    A short description outlines the development of commission focused short-term therapy (AFoG) for children and adolescents. Subsequently the generic principles of psychotherapy are applied to AFoG in order to underline the basic assumptions of this variation of systemic group therapy. Behavioural changes arising in different contexts (school, family, group therapy) show the need for an appropriate flexibility of group therapy techniques. The evaluation was accomplished using the Child Behaviour Checklist (CBCL 4-18) at the beginning and 3 month after the end of the group therapy. The results show positive effects which finally are discussed critically.

  2. Radiation therapy of peritoneal mesothelioma

    International Nuclear Information System (INIS)

    Lederman, G.; Recht, A.

    1986-01-01

    The role of radiation therapy in the treatment of peritoneal mesotheliomas remains ill-defined despite its association with the few long-term survivals reported for this disease. The rationale for local therapy is clear as the disease most often is confined to the peritoneal cavity at the time of initial diagnosis and remains there for much of the subsequent course. Effective local treatment of this intra-abdominal disease would likely improve survival. The absence of randomized studies has made analysis of the various treatments of the disease and the few reported success difficult. Nonetheless, scrutiny of the available data may offer insights and guide future clinical trials, as well as the clinician responsible for the treatment of current patients with peritoneal mesothelioma. The radiotherapeutic approach to oncology stresses anatomic considerations in an attempt to understand the patterns of spread of the primary tumor. The observed location and bulk of disease by clinical examination, radiologic study, surgical exploration, and autopsy suggest mechanisms of metastases (direct extension, lymphatic or hematogenous). This dictates the administration of radiation that best achieves a successful outcome

    This article discusses the benefits and limitations of inhalation therapy in horses. Inhalation drug therapy delivers the drug directly to the airways, thereby achieving maximal drug concentrations at the target site. Inhalation therapy has the additional advantage of decreasing systemic side effects. Inhalation therapy in horses is delivered by the use of nebulizers or pressured metered dose inhalers. It also requires the use of a muzzle or nasal mask in horses. Drugs most commonly delivered through inhalation drug therapy in horses include bronchodilators, antiinflammatories, and antimicrobials.

    To examine the occurrence of subsequent preterm birth (PTB) among women who experienced a cervical tear during prior delivery. A retrospective study conducted at a single teaching hospital on data from January 1994 to March 2014. The study group included all women who had a cervical tear detected at uterine and cervical examination, performed due to early postpartum hemorrhage. The control group consisted of women who delivered vaginally, experienced an early postpartum hemorrhage, and had an intact cervix at uterine and cervical examination. The control group was matched for maternal age and ethnicity at a ratio of 1:2. Women who had a cervical tear but then did not have a subsequent delivery, or had multiple fetal gestations or cervical cerclage at subsequent pregnancies were excluded. Primary outcome was spontaneous PTB rate (PTBs in other subsequent pregnancies. Overall, 389 women were included. Of all cases of cervical tear, 129 were identified eligible and included in the final analysis. The control group included 260 women with an intact cervix. No significant differences were found between the study and control groups in the incidence of spontaneous PTB in the immediate subsequent pregnancy [1.6% (2/129) vs. 3.8% (10/260), respectively, p = 0.35]. The incidence of any spontaneous PTBs in all subsequent pregnancies did not differ also [4.7% (6/129) vs. 7.3% (19/260), respectively, p = 0.31]. Cervical tear detected after delivery does not increase the risk of spontaneous PTB in subsequent pregnancies.

    Full Text Available Performance on working memory (WM tasks may partially be supported by long-term memory (LTM processing. Hence, brain activation recently being implicated in WM may actually have been driven by (incidental LTM formation. We examined which brain regions actually support successful WM processing, rather than being confounded by LTM processes, during the maintenance and probe phase of a WM task. We administered a four-pair (faces and houses associative delayed-match-to-sample (WM task using event-related fMRI and a subsequent associative recognition LTM task, using the same stimuli. This enabled us to analyze subsequent memory effects for both the WM and the LTM test by contrasting correctly recognized pairs with incorrect pairs for either task. Critically, with respect to the subsequent WM effect, we computed this analysis exclusively for trials that were forgotten in the subsequent LTM recognition task. Hence, brain activity associated with successful WM processing was less likely to be confounded by incidental LTM formation. The subsequent LTM effect, in contrast, was analyzed exclusively for pairs that previously had been correctly recognized in the WM task, disclosing brain regions involved in successful LTM formation after successful WM processing. Results for the subsequent WM effect showed no significantly activated brain areas for WM maintenance, possibly due to an insensitivity of fMRI to mechanisms underlying active WM maintenance. In contrast, a correct decision at WM probe was linked to activation in the retrieval success network (anterior and posterior midline brain structures. The subsequent LTM analyses revealed greater activation in left dorsolateral prefrontal cortex and posterior parietal cortex in the early phase of the maintenance stage. No supra-threshold activation was found during the WM probe. Together, we obtained clearer insights in which brain regions support successful WM and LTM without the potential confound of the

    Associations between depression/anxiety and pain are well established, but its directionality is not clear. We examined the associations between temporally previous mental disorders and subsequent self-reported chronic back/neck pain onset, and investigated the variation in the strength of associations according to timing of events during the life course, and according to gender. Data were from population-based household surveys conducted in 19 countries (N = 52,095). Lifetime prevalence and age of onset of 16 mental disorders according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, and the occurrence and age of onset of back/neck pain were assessed using the Composite International Diagnostic Interview. Survival analyses estimated the associations between first onset of mental disorders and subsequent back/neck pain onset. All mental disorders were positively associated with back/neck pain in bivariate analyses; most (12 of 16) remained so after adjusting for psychiatric comorbidity, with a clear dose-response relationship between number of mental disorders and subsequent pain. Early-onset disorders were stronger predictors of pain; when adjusting for psychiatric comorbidity, this remained the case for depression/dysthymia. No gender differences were observed. In conclusion, individuals with mental disorder, beyond depression and anxiety, are at higher risk of developing subsequent back/neck pain, stressing the importance of early detection of mental disorders, and highlight the need of assessing back/neck pain in mental health clinical settings. Previous mental disorders according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition are positively associated with subsequent back/neck pain onset, with a clear dose-response relationship between number of mental disorders and subsequent pain. Earlier-onset mental disorders are stronger predictors of subsequent pain onset, compared with later-onset disorders

The subsequent LTM effect, in contrast, was analyzed exclusively for pairs that previously had been correctly recognized in the WM task, disclosing brain regions involved in successful LTM formation after successful WM processing. Results for the subsequent WM effect showed no significantly activated brain areas for WM maintenance, possibly due to an insensitivity of fMRI to mechanisms underlying active WM maintenance. In contrast, a correct decision at WM probe was linked to activation in the "retrieval success network" (anterior and posterior midline brain structures). The subsequent LTM analyses revealed greater activation in left dorsolateral prefrontal cortex and posterior parietal cortex in the early phase of the maintenance stage. No supra-threshold activation was found during the WM probe. Together, we obtained clearer insights in which brain regions support successful WM and LTM without the potential confound of

    Music therapy is a predominantly non-verbal psychotherapy based on music improvisation, embedded in a therapeutic relationship. This is the reason why music therapy is also used to treat depression. To examine the efficacy of music therapy and to report on the results of recent research into the value of music therapy as a treatment for depression. We reviewed the literature on recent research into music therapy and depression, reporting on the methods used and the results achieved, and we assessed the current position of music therapy for depression in the context of evidence-based scientific research. A wide variety of research methods was used to investigate the effects of using music therapy as a psychotherapy. Most studies focused usually on the added value that music therapy brings to the standard form of psychiatric treatment, when administered with or without psychopharmacological support. Music therapy produced particularly significant and favourable results when used to treat patients with depression. Current research into music therapy and depression points to a significant and persistent reduction in patients' symptoms and to improvements in their quality of life. However, further research is needed with regard to the best methods of illustrating the effects of music therapy.

    2016-01-01

    The publication of this fourth edition, more than ten years on from the publication of Radiation Therapy Physics third edition, provides a comprehensive and valuable update to the educational offerings in this field. Led by a new team of highly esteemed authors, building on Dr Hendee’s tradition, Hendee’s Radiation Therapy Physics offers a succinctly written, fully modernised update. Radiation physics has undergone many changes in the past ten years: intensity-modulated radiation therapy (IMRT) has become a routine method of radiation treatment delivery, digital imaging has replaced film-screen imaging for localization and verification, image-guided radiation therapy (IGRT) is frequently used, in many centers proton therapy has become a viable mode of radiation therapy, new approaches have been introduced to radiation therapy quality assurance and safety that focus more on process analysis rather than specific performance testing, and the explosion in patient-and machine-related data has necessitated an ...

    Radon therapies are used since more than 100 years in human medicine. Today this method is controversially discussed due to the possible increase of ionizing radiation induced tumor risk. Although the exact mode of biological radiation effect on the cell level is still not known new studies show the efficiency of the radon therapy without side effect for instance for rheumatic/inflammatory or respiratory disorders.

    Approximately 1 in 20 unrelated donors are asked to make a second donation of hematopoietic progenitor cells, the majority for the same patient. Anthony Nolan undertook a study of subsequent hematopoietic progenitor cell donations made by its donors from 2005 to 2011, with the aims of predicting those donors more likely to be called for a second donation, assessing rates of serious adverse reactions and examining harvest yields. This was not a study of factors predictive of second allografts. During the study period 2591 donations were made, of which 120 (4.6%) were subsequent donations. The median time between donations was 179 days (range, 21–4016). Indications for a second allogeneic transplant included primary graft failure (11.7%), secondary graft failure (53.2%), relapse (30.6%) and others (1.8%). On multivariate analysis, bone marrow harvest at first donation was associated with subsequent donation requests (odds ratio 2.00, P=0.001). The rate of serious adverse reactions in donors making a subsequent donation appeared greater than the rate in those making a first donation (relative risk=3.29, P=0.005). Harvest yields per kilogram recipient body weight were equivalent between donations, although females appeared to have a lower yield at the subsequent donation. Knowledge of these factors will help unrelated donor registries to counsel their donors. PMID:23812935

  14. Satisfaction in motion: Subsequent search misses are more likely in moving search displays.

    People often conduct visual searches in which multiple targets are possible (e.g., medical X-rays can contain multiple abnormalities). In this type of search, observers are more likely to miss a second target after having found a first one (a subsequent search miss). Recent evidence has suggested that this effect may be due to a depletion of cognitive resources from tracking the identities and locations of found targets. Given that tracking moving objects is resource-demanding, would finding a moving target further increase the chances of missing a subsequent one? To address this question, we had participants search for one or more targets hidden among distractors. Subsequent search misses were more likely when the targets and distractors moved throughout the display than when they remained stationary. However, when the found targets were highlighted in a unique color, subsequent search misses were no more likely in moving displays. Together, these results suggest that the effect of movement is likely due to the increased cognitive demands of tracking moving targets. Overall, our findings reveal that activities that involve searching for moving targets (e.g., driving) are more susceptible to subsequent search misses than are those that involve searching for stationary targets (e.g., baggage screening).

    Systematic review to determine any association between imaging features of idiopathic mesenteric panniculitis (MP) and subsequent malignancy. Two researchers searched primary literature independently for imaging studies of MP. They extracted data focusing on methodology for unbiased patient accrual and capability to determine a link between MP and subsequent malignancy. They noted imaging features of MP. Data were accrued and meta-analysis intended. Fourteen of 675 articles were eligible; 1,226 patients. Only three (21 %) accrued patients prospectively. Twelve (86 %) studies described CT features. Follow-up varied widely; 1 month to 8 years. Prevalence of MP was influenced by accrual: 0.2 % for keyword search versus 1.7 % for consecutive series. Accrual bias affected nine (64 %) studies. 458 (38 %) of 1,209 patients had malignancy at accrual but varied widely (8-89 %), preventing meta-analysis. Sixty (6.4 %) of 933 patients developed new malignancy subsequently, also varying widely (0-11 %). Of just four studies that determined the proportion of unselected, consecutive patients with MP developing subsequent malignancy, three were retrospective and the fourth excluded patients with lymphadenopathy, likely excluding patients with MP. Studies were heterogeneous, with biased accrual. No available study can determine an association between MP and subsequent malignancy with certainty. (orig.)

    Reducing avoidable readmission and posthospitalization emergency department (ED) utilization has become a focus of quality-of-care measures and initiatives. For pediatric patients, no systematic efforts have assessed the evidence for interventions to reduce these events. We sought to synthesize existing evidence on pediatric discharge practices and interventions to reduce hospital readmission and posthospitalization ED utilization. PubMed and the Cumulative Index to Nursing and Allied Health Literature. Studies available in English involving pediatric inpatient discharge interventions with at least 1 outcome of interest were included. We utilized a modified Cochrane Good Practice data extraction tool and assessed study quality with the Downs and Black tool. Our search identified a total of 1296 studies, 14 of which met full inclusion criteria. All included studies examined multifaceted discharge interventions initiated in the inpatient setting. Overall, 2 studies demonstrated statistically significant reductions in both readmissions and subsequent ED visits, 4 studies demonstrated statistically significant reductions in either readmissions or ED visits, and 2 studies found statistically significant increases in subsequent utilization. Several studies were not sufficiently powered to detect changes in either subsequent utilization outcome measure. Interventions that demonstrated reductions in subsequent utilization targeted children with specific chronic conditions, providing enhanced inpatient feedback and education reinforced with postdischarge support. Interventions seeking to reduce subsequent utilization should identify an individual or team to assume responsibility for the inpatient-to-outpatient transition and offer ongoing support to the family via telephone or home visitation following discharge. © 2013 Society of Hospital Medicine.

    Skeletal myoblasts have been extensively used to study muscle growth and differentiation, and were recently tested for their application as cell therapy and as a gene delivery system to treat muscle and nonmuscle diseases. However, contamination of fibroblasts in isolated cells from skeletal muscle is one of the long-standing problems for routine expansion. This study aimed to establish a simple one-step process to purify myoblasts and maintain their purity during expansion. Mixed cells were preplated serially on laminin- and collagen type I-coated surfaces in a different array for 5, 10, and 15 min. Immunocytochemical staining with antibodies specific to myoblasts was performed to evaluate myoblast attachment efficiency, purity, and yield. It was found that laminin-coated surface favors the attachment of myoblasts. Highest myoblast purity of 78.9% ± 6.8% was achieved by 5 min of preplating only on the laminin-coated surface with a yield of 56.9% ± 3.3%. Primary cells, isolated from skeletal muscle (n = 4), confirm the enhancement of purity through preplating on laminin-coated surface for 5 min. Subsequent expansion after preplating enhanced myoblast purity due to an increase in myoblast growth than fibroblasts. Myoblast purity of ∼ 98% was achieved when another preplating was performed during passaging. In conclusion, myoblasts can be purified and efficiently expanded in one step by preplating on laminin-coated surface, which is a simple and robust technique.

    The present study was undertaken to examine the effect of marrow preservation at 4 degrees C on subsequent long-term culture, which evaluates both hematopoietic precursor cells and hematopoietic microenvironmental cells. Storage of unfractionated marrow was superior to storage of buffy-coat cells in tissue culture medium with 20% fetal calf serum. CFU-C recovery in unfractionated marrow was 48.4% at four days and 21.4% at seven days. Long-term marrow cultures from cells stored at 4 degrees C for up to seven days produced CFU-C for up to seven weeks and established confluent marrow stromal cell layers. Suspension cultures of marrow cells preserved at 4 degrees C for seven days cultured with irradiated allogeneic marrow stromal cell layers from normal long-term marrow cultures showed significantly increased CFU-C production from week 2 to week 5 when compared with the control cultures without adherent cell layers. These data suggest that marrow storage at 4 degrees C for up to seven days preserves early hematopoietic precursor cells and microenvironmental cells and may be used for autologous rescue from marrow ablative therapy

    Prolonged viewing of a visual stimulus can result in sensory adaptation, giving rise to perceptual phenomena such as the tilt aftereffect (TAE). However, it is not known if short-term memory maintenance induces such effects. We examined how visual short-term memory (VSTM) maintenance modulates the strength of the TAE induced by subsequent visual adaptation. We reasoned that if VSTM maintenance induces aftereffects on subsequent encoding of visual information, then it should either enhance or reduce the TAE induced by a subsequent visual adapter, depending on the congruency of the memory cue and the adapter. Our results were consistent with this hypothesis and thus indicate that the effects of VSTM maintenance can outlast the maintenance period.

  20. Firms’ Negative Perceptions on Patents, Technology Management Strategies, and Subsequent Performance

    Full Text Available While patents do have many advantages, their disadvantages include requiring disclosure of technical information and imposing the burden of patenting and litigation costs. In this study, we investigate the relationship between a firm’s negative perception on patents, technology management strategies, and subsequent performance. For this purpose, we use a categorical canonical correlation analysis of the top 200, large, R&D-intensive firms in Korea. We find that negative perceptions such as burdensome transaction costs, non-patenting culture, and uncertainty of the outcome of patent litigation are associated with firms’ technology management strategies, such as purchase of licenses, and subsequent performance, such as an increase in the number of inventions from the cross-fertilization of different technologies. The results of this study are expected to contribute to a better understanding of firms’ negative attitudes toward the effects of patents, their subsequent technology management strategies, and resulting performance.

    The irradiation notably influences responsiveness of cellulose and lignin to the subsequent pyrogenic distillation though both weight and the form of samples do not change almost at doses up to 3 MGy. Decreases in overpoint of lignin and cellulose irradiated at 2.2 MGy are ∼80°and ∼100°, respectively. Third of condensate from cellulose and almost half from lignin are distilled-off at lower temperatures. The thermally instable compounds convertible mainly to furans via subsequent heating are forming in cellulose. Distillation of the irradiated lignin gives less tar which, however, is richer by methoxy-phenols. In distilled-off water–organic fraction the content of soluble organic compounds is increased. - Highlights: • Irradiation facilitates subsequent dry distillation of cellulose and lignin. • Overpoints of irradiated samples are decreasing. • Furans and methoxy-phenols formation improves

    Declarative and non-declarative memories are thought be supported by two distinct memory systems that are often posited not to interact. However, Wagner, Maril, and Schacter (2000a) reported that at the time priming was assessed, greater behavioural and neural priming was associated with lower levels of subsequent recognition memory, demonstrating an interaction between declarative and non-declarative memory. We examined this finding using a similar paradigm, in which participants made the same or different semantic word judgements following a short or long lag and subsequent memory test. We found a similar overall pattern of results, with greater behavioural priming associated with a decrease in recognition and recall performance. However, neither various within-participant nor various between-participant analyses revealed significant correlations between priming and subsequent memory performance. These data suggest that both lag and task have effects on priming and declarative memory performance, but that they are largely independent and occur in parallel.

    Knowledge of the role of brain maturation in the development of cognitive abilities derives primarily from studies of school-age children to adults. Little is known about the morphological features of the neonatal brain that support the subsequent development of abilities in early childhood, when maturation of the brain and these abilities are the most dynamic. The goal of our study was to determine whether brain morphology during the neonatal period supports early cognitive development through 2 years of age. We correlated morphological features of the cerebral surface assessed using deformation-based measures (surface distances) of high-resolution MRI scans for 33 healthy neonates, scanned between the first to sixth week of postmenstrual life, with subsequent measures of their motor, language, and cognitive abilities at ages 6, 12, 18, and 24 months. We found that morphological features of the cerebral surface of the frontal, mesial prefrontal, temporal, and occipital regions correlated with subsequent motor scores, posterior parietal regions correlated with subsequent language scores, and temporal and occipital regions correlated with subsequent cognitive scores. Measures of the anterior and middle portions of the cingulate gyrus correlated with scores across all three domains of ability. Most of the significant findings were inverse correlations located bilaterally in the brain. The inverse correlations may suggest either that a more protracted morphological maturation or smaller local volumes of neonatal brain tissue supports better performance on measures of subsequent motor, language, and cognitive abilities throughout the first 2 years of postnatal life. The correlations of morphological measures of the cingulate with measures of performance across all domains of ability suggest that the cingulate supports a broad range of skills in infancy and early childhood, similar to its functions in older children and adults.

  4. IMPACT OF SEX COMPOSITION OF LIVING CHILDREN AND COUPLES' AGREEMENT ON SUBSEQUENT FERTILITY IN INDIA.

    The desire for children could be considered a reliable predictor of subsequent fertility. At the same time, the sex composition of surviving children, along with other demographic and socioeconomic factors, may affect a couple's fertility desire and, therefore, their subsequent fertility. This study examined the impact of the sex composition of living children and a couple's agreement on fertility desire on their subsequent fertility in India using data came from two rounds of nationally representative surveys: the India Human Development Survey (IHDS)-I (2004-05) and IHDS-II (2011-12). To understand which factors affect the chances of an additional pregnancy or childbirth, a random effects logistic regression model was applied to the panel data. It was found that the fertility desires of both marital partners were important in determining the chances of subsequent fertility. About 35% of the couples wanting to limit children had undergone pregnancy or childbirth, while 76% of the couples wanting more children had conceived or given birth to children. In the case of discordance between the spouses, subsequent fertility was found to remain intermediate between those agreeing to continue childbirth and those wanting to limit it. The findings also affirmed that child sex preference, specifically son preference, still persists in Indian society. More than 80% of the couples with only daughters in IHDS-I mutually wanted to have additional children, whereas in families that only had sons, the chance of a subsequent pregnancy was inversely associated with the number of sons. Strong patriarchal settings, combined with cultural and socioeconomic factors, affect the persistence of sex preference in India. Programmes aimed at increasing family planning use need to address son preference and should include components that promote the value of girl children.

    The objective is to investigate the effect of atmospheric pressure dielectric barrier discharge (APDBD) plasma and subsequent cellulase enzyme treatment on the properties of flax fabrics. The changes of surface morphology and structure, physico-mechanical properties, hydrophilicity, bending properties, whiteness, and dyeing properties of the treated substrate were investigated. The results indicated that atmospheric pressure dielectric barrier discharge plasma pre-treatment and subsequent cellulase enzyme treatment could diminish the hairiness of flax fabrics, endowing the flax fabrics with good bending properties, water uptake and fiber accessibility while keeping their good mechanical properties compared with those treated with cellulase enzyme alone.

    2018-02-01

    This project explored whether disruption of articulation during listening impacts subsequent speech production in 4-yr-olds with and without speech sound disorder (SSD). During novel word learning, typically-developing children showed effects of articulatory disruption as revealed by larger differences between two acoustic cues to a sound contrast, but children with SSD were unaffected by articulatory disruption. Findings suggest that, when typically developing 4-yr-olds experience an articulatory disruption during a listening task, the children's subsequent production is affected. Children with SSD show less influence of articulatory experience during perception, which could be the result of impaired or attenuated ties between perception and articulation.

    We evaluated the subsequent memory and forgotten effects for Chinese using event-related fMRI. Sixteen normal subjects were recruited and performing incidental memory tasks where semantic decision was required during memory encoding. Consistent with previous studies, our results showed bilateral frontal regions as the main locus for the subsequent memory effect. However, contrast between miss and hit responses revealed larger activation in bilateral superior temporal gyrus. We proposed that larger activation in the superior temporal gyrus may reflect alteration of self-monitoring process which resulted in unsuccessful memory encoding for the miss items.

    Folate-based radiopharmaceuticals have the potential to be used for imaging and therapy of tumours positive for the folate receptor (FR). We describe the in vitro and in vivo evaluation of a DOTA-folate conjugate. Radiolabelling of the DOTA-folate was carried out via standard procedures using {sup 111}InCl{sub 3} and {sup 177}LuCl{sub 3}, respectively. The distribution coefficient (log D) was determined in octanol/PBS (pH 7.4). Tissue distribution was investigated in nude mice bearing KB tumour xenografts at different time points after administration of {sup 111}In-DOTA-folate (radiofolate 1) or {sup 177}Lu-DOTA-folate (radiofolate 2) (1 MBq, 1 nmol per mouse). Pemetrexed (PMX, 400 {mu}g) was injected 1 h prior to the radiofolate in order to reduce renal uptake. Images were acquired with a SPECT/CT camera 24 h after injection of the radiofolate (40-50 MBq, 3 nmol per mouse). The hydrophilic character of the DOTA-folate was represented by a low log D value (radiofolate 1 -4.21{+-}0.11). In vivo, maximal tumour uptake was found 4 h after injection (radiofolate 1 5.80{+-}0.55% ID/g; radiofolate 2 7.51{+-}1.25% ID/g). In FR-positive kidneys there was considerable accumulation of the radiofolates (radiofolate 1 55.88{+-}3.91% ID/g; radiofolate 2 57.22{+-}11.05% ID/g; 4 h after injection). However, renal uptake was reduced by preinjection of PMX (radiofolate 1 9.52{+-}1.07% ID/g; radiofolate 2 13.43{+-}0.54% ID/g; 4 h after injection) whereas the tumour uptake was retained (radiofolate 1 6.32{+-}0.41% ID/g; radiofolate 2 8.99{+-}0.43% ID/g; 4 h after injection). SPECT/CT images clearly confirmed favourable tissue distribution of the novel radiofolates and the positive effect of PMX. The preliminary requirements for the therapeutic use of the novel DOTA-folate are met by its favourable tissue distribution that can be ascribed to its hydrophilic properties and combined administration with PMX.

    Doycheva, D; Deuter, C; Zierhut, M

    2014-12-01

    Intermediate uveitis is a form of intraocular inflammation in which the vitreous body is the major site of inflammation. Intermediate uveitis is primarily treated medicinally and systemic corticosteroids are the mainstay of therapy. When recurrence of uveitis or side effects occur during corticosteroid therapy an immunosuppressive treatment is required. Cyclosporine A is the only immunosuppressive agent that is approved for therapy of uveitis in Germany; however, other immunosuppressive drugs have also been shown to be effective and well-tolerated in patients with intermediate uveitis. In severe therapy-refractory cases when conventional immunosuppressive therapy has failed, biologics can be used. In patients with unilateral uveitis or when the systemic therapy is contraindicated because of side effects, an intravitreal steroid treatment can be carried out. In certain cases a vitrectomy may be used.

    With increased survival of increasing numbers of cancer patients as a result of therapy, the consequences, early and late, of the therapies must be realized. It is the treating physician's duty to preserve as much reproductive potential as possible for patients, consistent with adequate care. With radiotherapy this means shielding the gonads as much as possible, optimal but not excessive doses and fields, oophoropexy, or sperm collection and storage prior to irradiation. With chemotherapy it means the shortest exposure to drugs consistent with best treatment and prior to therapy the collection and storage of sperm where facilities are available. At present this is still an experimental procedure. Artificial insemination for a couple when the male has received cancer therapy is another alternative. Finally, it is the responsibility of physicians caring for patients with neoplasms to be knowledgeable about these and all other effects of therapy so that patients may be counseled appropriately and understand the implications of therapy for their life

  19. Is Bicarbonate Therapy Useful?

    Science.gov (United States)

    Hopper, Kate

    2017-03-01

    Despite concerns about the negative effects of metabolic acidosis, there is minimal evidence that sodium bicarbonate administration is an effective treatment. In addition, sodium bicarbonate therapy is associated with many adverse effects, including paradoxic intracellular acidosis, hypokalemia, hypocalcemia, hypernatremia, and hyperosmolality. Definitive recommendations regarding bicarbonate therapy are challenging as there is little high-quality evidence available. In most clinical scenarios of metabolic acidosis, treatment efforts should focus on resolution of the underlying cause, and sodium bicarbonate therapy should be used with caution, if at all. An exception to this is kidney disease, wherein sodium bicarbonate therapy may have a valuable role. Published by Elsevier Inc.

  1. Medical Art Therapy

    Directory of Open Access Journals (Sweden)

    Birgul Aydin

    2012-03-01

    Full Text Available Art therapy is a form of expressive therapy that uses art materials. Art therapy combines traditional psychotherapeutic theories and techniques with an understanding of the psychological aspects of the creative process, especially the affective properties of the different art materials. Medical art therapy has been defined as the clinical application of art expression and imagery with individuals who are physically ill, experiencing physical trauma or undergoing invasive or aggressive medical procedures such as surgery or chemotherapy and is considered as a form of complementary or integrative medicine. Several studies have shown that patients with physical illness benefit from medical art therapy in different aspects. Unlike other therapies, art therapy can take the patients away from their illness for a while by means of creative activities during sessions, can make them forget the illness or lost abilities. Art therapy leads to re-experiencing normality and personal power even with short creative activity sessions. In this article definition, influence and necessity of medical art therapy are briefly reviewed.

    Biological therapies and new imaging techniques have changed the therapeutic and diagnostic approach to spondyloarthritis. In patients with axial spondyloarthritis, tumor necrosis factor α (TNFα) inhibitor treatment is currently the only effective therapy in patients for whom conventional therapy with nonsteroidal anti-inflammatory drugs (NSAIDs) has failed. TNFα inhibitor treatment is more effective in preventing articular damage in peripheral joints than in axial ones. It is important to treat patients at an early stage of disease to reduce disease progression; moreover it is necessary to identify causes of therapy inefficacy in preventing joint damage in the axial subset.

  15. Prior methylphenidate self-administration alters the subsequent reinforcing effects of methamphetamine in rats.

    Science.gov (United States)

    Baladi, Michelle G; Nielsen, Shannon M; Umpierre, Anthony; Hanson, Glen R; Fleckenstein, Annette E

    2014-12-01

    Methylphenidate (MPD) is clinically effective in treating the symptoms of attention-deficit hyperactivity disorder; however, its relatively widespread availability has raised public health concerns on nonmedical use of MPD among certain adult populations. Most preclinical studies investigate whether presumed therapeutically relevant doses of MPD alter sensitivity to the reinforcing effects of other drugs, but it remains unclear whether doses of MPD likely exceeding therapeutic relevance impact the subsequent reinforcing effects of drugs. To begin to address this question, the effect of prior MPD self-administration (0.56 mg/kg/infusion) on the subsequent reinforcing effects of methamphetamine (METH, 0.032 or 0.1 mg/kg/infusion) was investigated in male Sprague-Dawley rats. For comparison, it was also determined whether prior experimenter-administered MPD, injected daily at a presumed therapeutically relevant dose (2 mg/kg), altered the subsequent reinforcing effects of METH. Results indicated that, under the current conditions, only a history of MPD self-administration increased sensitivity to the subsequent reinforcing effects of METH. Furthermore, MPD did not impact food-maintained responding, suggesting that the effect of MPD might be specific to drug reinforcers. These data suggest that short-term, nonmedical use of MPD might alter the positive reinforcing effects of METH in a manner relevant to vulnerability to drug use in humans.

  19. Emotion regulation during the encoding of emotional stimuli: Effects on subsequent memory.

    Science.gov (United States)

    Leventon, Jacqueline S; Bauer, Patricia J

    2016-02-01

    In the adult literature, emotional arousal is regarded as a source of the enhancing effect of emotion on subsequent memory. Here, we used behavioral and electrophysiological methods to examine the role of emotional arousal on subsequent memory in school-age children. Furthermore, we implemented a reappraisal instruction to manipulate (down-regulate) emotional arousal at encoding to examine the relation between emotional arousal and subsequent memory. Participants (8-year-old girls) viewed emotional scenes as electrophysiological (EEG) data were recorded and participated in a memory task 1 to 5days later where EEG and behavioral responses were recorded; participants provided subjective ratings of the scenes after the memory task. The reappraisal instruction successfully reduced emotional arousal responses to negative stimuli but not positive stimuli. Similarly, recognition performance in both event-related potentials (ERPs) and behavior was impaired for reappraised negative stimuli but not positive stimuli. The findings indicate that ERPs are sensitive to the reappraisal of negative stimuli in children as young as 8years. Furthermore, the findings suggest an interaction of emotion and memory during the school years, implicating the explanatory role of emotional arousal at encoding on subsequent memory performance in female children as young as 8years.

  2. The Influence of Pre-Exercise Glucose versus Fructose Ingestion on Subsequent Postprandial Lipemia

    Directory of Open Access Journals (Sweden)

    Tsung-Jen Yang

    2018-01-01

    Full Text Available Ingestion of low glycemic index (LGI carbohydrate (CHO before exercise induced less insulin response and higher fat oxidation than that of high GI (HGI CHO during subsequent exercise. However, the effect on the subsequent postprandial lipid profile is still unclear. Therefore, the aim of this study was to investigate ingestion of CHO drinks with different GI using fructose and glucose before endurance exercise on the subsequent postprandial lipid profile. Eight healthy active males completed two experimental trials in randomized double-blind cross-over design. All participants ingested 500 mL CHO (75 g solution either fructose (F or glucose (G before running on the treadmill at 60% VO2max for 1 h. Participants were asked to take an oral fat tolerance test (OFTT immediately after the exercise. Blood samples were obtained for plasma and serum analysis. The F trial was significantly lower than the G trial in TG total area under the curve (AUC; 9.97 ± 3.64 vs. 10.91 ± 3.56 mmol × 6 h/L; p = 0.033 and incremental AUC (6.57 ± 2.46 vs. 7.14 ± 2.64 mmol/L × 6 h, p = 0.004. The current data suggested that a pre-exercise fructose drink showed a lower postprandial lipemia than a glucose drink after the subsequent high-fat meal.

    This study was undertaken to determine the incidence of subsequent oophorectomy due to ovarian pathology or ovarian cancer in women with prior hysterectomy for benign gynecologic conditions at Chiang Mai University Hospital. Medical records of women who underwent hysterectomy for benign gynecologic diseases and pre-cancerous lesions between January 1, 2004 and December 31, 2013 at Chiang Mai University Hospital were retrospectively reviewed. The incidence and indications of oophorectomy following hysterectomy were analyzed. During the study period, 1,035 women had hysterectomy for benign gynecologic conditions. Of these, 590 women underwent hysterectomy with bilateral salpingo-oophorectomy and 445 hysterectomy with bilateral ovarian preservation or unilateral salpingo-oophorectomy. The median age was 47 years (range, 11-75 years). Ten women (2.45 %) had subsequent oophorectomy for benign ovarian cysts. No case of ovarian cancer was found. The mean time interval between hysterectomy and subsequent oophorectomy was 43.1 months (range, 2-97 months) and the mean follow-up time for this patient cohort was 51 months (range, 1.3-124.9 months). According to our hospital-based data, the incidence of subsequent oophorectomy in women with prior hysterectomy for benign gynecologic conditions is low and all present with benign conditions.

    To compare changes in oxygenation after manual turning and percussion (standard therapy) and after automated rotation and percussion (kinetic therapy). Randomized crossover trial. General and cardiac pediatric intensive care units. Intubated and mechanically ventilated pediatric patients who had an arterial catheter and no contraindications to using a PediDyne bed. Patients were placed on a PediDyne bed (Kinetic Concepts) and received 18 hrs blocks of standard and kinetic therapy in an order determined by randomization. Arterial blood gases were measured every 2 hrs during each phase of therapy. Oxygenation index and arterial-alveolar oxygen tension difference [P(A-a)O(2)] were calculated. Indexes calculated at baseline and after each 18-hr phase of therapy were analyzed. Fifty patients were enrolled. Data from 15 patients were either not collected or not used due to reasons that included violation of protocol and inability to tolerate the therapies in the study. Indexes of oxygenation were not normally distributed and were compared using Wilcoxon signed rank testing. Both therapies led to improvements in oxygenation, but only those from kinetic therapy achieved statistical significance. In patients receiving kinetic therapy first, median oxygenation index decreased from 7.4 to 6.19 (p = .015). The median P(A-a)O(2) decreased from 165.2 to 126.4 (p = .023). There were continued improvements in oxygenation after the subsequent period of standard therapy, with the median oxygenation index decreasing to 5.52 and median P(A-a)O(2) decreasing to 116.0, but these changes were not significant (p = .365 and .121, respectively). When standard therapy was first, the median oxygenation index decreased from 8.83 to 8.71 and the median P(a-a)o(2) decreased from 195.4 to 186.6. Neither change was significant. Median oxygenation index after the subsequent period of kinetic therapy was significantly lower (7.91, p = .044) and median P(A-a)O(2) trended lower (143.4, p = .077

    The initial effect of anticancer therapy, such as radiation and chemotherapy, is on the rapidly proliferating cells of the oral epithelium. As a consequence, the epithelium may show atrophy and ulceration. The sites of these alterations are related to the rate of epithelial proliferation. Regions of rapid proliferation, such as the oral lining mucosa, show a greater frequency of ulceration than masticatory mucosa or skin. Subsequent changes in the mucosa reflect damage to connective tissue, including fibroblasts and blood vessels. This results in hyalinization of collagen, hypovascularity, and ischemia. Indirect effects of anticancer therapy may include granulocytopenia and reduced salivary secretion, so that the protective mucin coating of the epithelium is compromised. These changes result in tissue with reduced barrier function and impaired ability to heal and to resist entry of pathogens, thus increasing the risk of systemic infections

    Radioiodine therapy of benign and malignant thyroid diseases is a well-established procedure in Nuclear Medicine. However, the therapeutic use of radioisotopes in other diseases is relatively unknown among our refering physicians. The therapeutic effects of intraarticular (rheumatoid arthritis) and intracavitary (pleural and peritoneal carcinosis) applications yields good results. The radiophosphorus therapy in polycythemia vera rubra has always to be considered as an alternative to chemotherapy. The use of analgetics may be reduced by pain therapy of bone metastasis by injection of bone-seeking beta emitters like Rh-186 HEDP. Other procedures like therapeutic application of meta-iodo-benzylguanidine in neuroblastoma and malignant pheochromocytoma resulted in at least remissions of the disease. Radioimmunotherapy needs further evaluation before it can be recommended as a routine procedure. (orig.).

    In a retrospective population-based study we assessed whether and how self-reported former fractures sustained at the ages of 20-34 are associated with subsequent fractures sustained at the ages of 35-57. The 12,162 women who responded to fracture questions of the baseline postal enquiry (in 1989) of the Kuopio Osteoporosis Study, Finland formed the study population. They reported 589 former and 2092 subsequent fractures. The hazard ratio (HR), with 95% confidence interval (CI), of a subsequent fracture was 1.9 (1.6-2.3) in women with the history of a former fracture compared with women without such a history. A former low-energy wrist fracture was related to subsequent low-energy wrist [HR = 3.7 (2.0-6.8)] and high-energy nonwrist [HR = 2.4 (1.3-4.4)] fractures, whereas former high-energy nonwrist fractures were related only to subsequent high-energy nonwrist [HR = 2.8 (1.9-4.1)] but not to low-energy wrist [HR = 0.7 (0.3-1.8)] fractures. The analysis of bone mineral density (BMD) data of a subsample of premenopausal women who underwent dual x-ray absorptiometry (DXA) during 1989-91 revealed that those with a wrist fracture due to a fall on the same level at the age of 20-34 recorded 6.5% lower spinal (P = 0.140) and 10.5% lower femoral (P = 0.026) BMD than nonfractured women, whereas the corresponding differences for women with a former nonwrist fracture due to high-energy trauma were -1.8% (P = 0.721) and -2.4% (P = 0. 616), respectively. Our results suggest that an early premenopausal, low-energy wrist fracture is an indicator of low peak BMD which predisposes to subsequent fractures in general, whereas early high-energy fractures are mainly indicators of other and more specific extraskeletal factors which mainly predispose to same types of subsequent fractures only.

    The risk of metachronous colorectal cancer is high after surgical resection for first colon cancer in Lynch syndrome. This study aimed to examine whether extended surgery decreases the risk of subsequent colorectal cancer and improves long-term survival. This was a retrospective study. Data were collected from a nationwide registry. Two hundred forty-two Lynch syndrome pathogenic variant carriers who underwent surgery for a first colon cancer from 1984 to 2009 were included. Patients underwent standard segmental colectomy (n = 144) or extended colectomy (n = 98) for colon cancer. Patients were followed a median of 14.6 up to 25 years. Risk of subsequent colorectal cancer in either group, overall and disease-specific survival, and operative mortality were the primary outcomes measured. Subtotal colectomy decreased the risk of subsequent colorectal cancer (HR, 0.20; 95% CI, 0.08-0.52; p = 0.001), compared with segmental resection. Subsequent colorectal cancer decreased in MLH1 carriers. The MSH2 carriers showed no statistical difference, possibly because of their small number. Disease-specific and overall survival within 25 years did not differ between the standard and extended surgeries (82.7% vs 87.2%, p = 0.76 and 47.2% vs 41.4%, p = 0.83). The cumulative risk of subsequent colorectal cancer was 20% in 10 years and 47% within 25 years after standard resection and 4% and 9% after extended surgery. The cumulative risk of metachronous colorectal cancer was 7% within 25 years after subtotal colectomy with ileosigmoidal anastomosis. One patient died of postoperative septicemia within 30 days after segmental colectomy. Data on surgical procedures were primarily collected retrospectively. Lynch syndrome pathogenic variant carriers may undergo subtotal colectomy to manage first colon cancer and avoid repetitive abdominal surgery and to reduce the remaining bowel to facilitate easier endoscopic surveillance. It provides no survival benefit, compared with segmental colon

    While the primary goal of ranking applicants for surgical residency training positions is to identify the candidates who will subsequently perform best as surgical residents, the effectiveness of the ranking process has not been adequately studied. We evaluated our general surgery resident recruitment process between 2001 and 2011 inclusive, to determine if our recruitment ranking parameters effectively predicted subsequent resident performance. We identified 3 candidate ranking parameters (United States Medical Licensing Examination [USMLE] Step 1 score, unadjusted ranking score [URS], and final adjusted ranking [FAR]), and 4 resident performance parameters (American Board of Surgery In-Training Examination [ABSITE] score, PGY1 resident evaluation grade [REG], overall REG, and independent faculty rating ranking [IFRR]), and assessed whether the former were predictive of the latter. Analyses utilized Spearman correlation coefficient. We found that the URS, which is based on objective and criterion based parameters, was a better predictor of subsequent performance than the FAR, which is a modification of the URS based on subsequent determinations of the resident selection committee. USMLE score was a reliable predictor of ABSITE scores only. However, when we compared our worst residence performances with the performances of the other residents in this evaluation, the data did not produce convincing evidence that poor resident performances could be reliably predicted by any of the recruitment ranking parameters. Finally, stratifying candidates based on their rank range did not effectively define a ranking cut-off beyond which resident performance would drop off. Based on these findings, we recommend surgery programs may be better served by utilizing a more structured resident ranking process and that subsequent adjustments to the rank list generated by this process should be undertaken with caution.

    Potentially inappropriate medication (PIM) is associated with an increased risk for detrimental health outcomes in elderly patients. Some antidepressant drugs are considered as PIM, but previous research on the association between antidepressants and subsequent dementia has been inconclusive. Therefore, we investigated whether the intake of antidepressants, particularly of those considered as PIM according to the Priscus list, would predict incident dementia. We used data of a prospective cohort study of non-demented primary care patients (n = 3239, mean age = 79.62) to compute Cox proportional hazards models. The risk for subsequent dementia was estimated over eight follow-ups up to 12 years depending on antidepressant intake and covariates. The intake of antidepressants was associated with an increased risk for subsequent dementia (HR = 1.53, 95% CI: 1.16-2.02, p = .003; age-, sex-, education-adjusted). PIM antidepressants (HR = 1.49, 95% CI: 1.06-2.10, p = .021), but not other antidepressants (HR = 1.04, 95% CI: 0.66-1.66, p = .863), were associated with an increased risk for subsequent dementia (in age-, sex-, education-, and depressive symptoms adjusted models). Significant associations disappeared after global cognition at baseline was controlled for. Methodological limitations such as selection biases and self-reported drug assessments might have influenced the results. Only antidepressants considered as PIM were associated with an increased subsequent dementia risk. Anticholinergic effects might explain this relationship. The association disappeared after the statistical control for global cognition at baseline. Nonetheless, physicians should avoid the prescription of PIM antidepressants in elderly patients whenever possible. Copyright © 2017 Elsevier B.V. All rights reserved.

    Major depressive disorder (MDD) has been associated with an increased risk of subsequent Parkinson's disease (PD) in case-control and cohort studies. However, depression alone is unlikely to be a useful marker of prodromal PD due to its low specificity. In this longitudinal observational study, we assessed whether the presence of other potential markers of prodromal PD predicts the subsequent development of PD in MDD patients. Of 57 patients with severe MDD but no diagnosis of PD who underwent a structured interview, olfactory and motor investigation and transcranial sonography at baseline, 46 (36 women; mean age 54.9 ± 11.7 years) could be followed for up to 11 (median, 10) years. Three patients (2 women; age 64, 65 and 70 years) developed definite PD after 1, 7, and 9 years, respectively. The combined finding of mild asymmetric motor slowing, idiopathic hyposmia, and substantia nigra hyperechogenicity predicted subsequent PD in all patients who could be followed for longer than 1 year. Out of the whole study cohort, only the subjects with subsequent PD presented with the triad of asymmetric motor slowing, idiopathic hyposmia, and substantia nigra hyperechogenicity in combination with at least two out of four reportable risk factors (family history of PD, current non-smoker, non-coffee drinker, constipation) at baseline investigation. Post-hoc analysis revealed that additional rating of eye and eye-lid motor abnormalities might further improve the prediction of PD in larger cohorts. Findings of this pilot-study suggest that MDD patients at risk of subsequent PD can be identified using an inexpensive non-invasive diagnostic battery.

  17. Recent intensified impact of December Arctic Oscillation on subsequent January temperature in Eurasia and North Africa

    This study reveals an intensified influence of December Arctic Oscillation (AO) on the subsequent January surface air temperature (SAT) over Eurasia and North Africa in recent decades. The connection is statistically insignificant during 1957/58-1979/80 (P1), which becomes statistically significant during 1989/90-2011/12 (P2). The possible causes are further investigated. Associated with positive December AO during P2, significant anomalous anticyclone emerges over the central North Atlantic, which is accompanied with significant westerly and easterly anomalies along 45°-65°N and 20°-40°N, respectively. This favors the significant influence of December AO on the subsequent January SAT and atmospheric circulation over Eurasia and North Africa via triggering the North Atlantic tripole sea surface temperature (SST) anomaly that persists into the subsequent January. By contrast, the December AO-related anomalous anticyclone during P1 is weak and is characterized by two separate centers located in the eastern and western North Atlantic. Correspondingly, the westerly and easterly anomalies over the North Atlantic Ocean are weak and the-related tripole SST anomaly is not well formed, unfavorable for the persistent impact of the December AO into the subsequent January. Further analyses indicate that the different anomalous anticyclone associated with the December AO over the North Atlantic may be induced by the strengthened synoptic-scale eddy feedbacks over the North Atlantic, which may be related to the interdecadal intensification of the storm track activity. Additionally, the planetary stationary wave related to the December AO propagates from surface into upper stratosphere at mid-latitudes during P2, which further propagates downward to the troposphere and causes anomalous atmospheric circulation in the subsequent January.

    Clostridium difficile infection (CDI) is a common nosocomial diarrheal illness increasingly associated with mortality in United States. The underlying factors and mechanisms behind the recent increases in morbidity from CDI have not been fully elucidated. Murine models suggest a mucosal barrier breakdown leads to bacterial translocation and subsequent bloodstream infection (BSI). This study tests the hypothesis that CDI is associated with subsequent BSI in humans. We conducted a retrospective cohort study on 1132 inpatients hospitalized >72 h with available stool test results for toxigenic C. difficile. The primary outcome was BSI following CDI. Secondary outcomes included 30-day mortality, colectomy, readmission, and ICU admission. Unadjusted and adjusted logistic regression models were developed. CDI occurred in 570 of 1132 patients (50.4%). BSI occurred in 86 (7.6%) patients. Enterococcus (14%) and Klebsiella (14%) species were the most common organisms. Patients with BSI had higher comorbidity scores and were more likely to be male, on immunosuppression, critically ill, and have a central venous catheter in place. Of the patients with BSI, 36 (42%) had CDI. CDI was not associated with subsequent BSI (OR 0.69; 95% CI 0.44-1.08; P = 0.103) in unadjusted analysis. In multivariable modeling, CDI appeared protective against subsequent BSI (OR 0.57; 95% CI 0.34-0.96; P = 0.036). Interaction modeling suggests a complicated relationship among CDI, BSI, antibiotic exposure, and central venous catheter use. In this cohort of inpatients that underwent testing for CDI, CDI was not a risk factor for developing subsequent BSI. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Although the many positive and negative psychosocial consequences of alcohol use are well documented, evidence of the association between prior drinking consequences and subsequent alcohol-related outcomes is mixed. Social learning theory highlights that cognitive appraisals of prior drinking consequences play a crucial intermediate role in the relation of prior drinking consequences with subsequent alcohol-related outcomes. This prospective study was designed to test the mediating effects of subjective evaluations (i.e., perceived valence and controllability) in the association of prior drinking consequences with change in binge drinking and drinking consequences over time. Participants were 171 college students (69% female, 74% White, M age = 18.95 years, SD = 1.35) who completed 2 online surveys, with an average interval of 68 days (SD = 10.22) between assessments. Path analyses of the data did not support mediational effects of perceived valence or controllability of prior drinking consequences on subsequent alcohol-related outcomes. Specifically, greater frequency of negative consequences was associated with lower perceived valence and controllability, and greater frequency of positive consequences was associated with lower perceived controllability of the experienced consequences. However, perceptions of valence and controllability were not in turn associated with subsequent binge drinking and drinking consequences. Instead, greater frequency of positive consequences was directly associated with greater subsequent frequency of binge drinking. Findings highlight the importance of prior positive consequences in the escalation of binge drinking over a short period of time, although this relation may not be accounted for by perceptions of valence and controllability of the prior drinking consequences.

    Between 1973 and 1985, 105 patients received radiation therapy as all or part of their treatment for pituitary tumor at the New York University Medical Center. Of these, 48 patients underwent computed tomography (CT) at a minimum of 2 years following treatment, with detailed reports available for analysis of tumor regression. There were 28 men with a median age of 46 years (range, 18-71 years) and 20 women with a median age of 53 years (range, 28-80 years). Tumors were classified as secretory in 23 patients, nonsecretory in 21, and undetermined in four. Sixteen patients were treated with radiation therapy alone, 23 patients with surgery and radiation therapy, and the other with bromocriptine and radiation therapy, with or without surgery. With a median follow-up of 5 years (range, 2-14 years), 16 patients developed an empty sella, 25 patients had residual sellar mass, and seven patients had persistent extrasellar components or no change in their intrasellar mass. Among patients who did not have hypopituitarism at the inception of radiation therapy, five of 13 with empty sellas and 12 of 22 with residual mass subsequently required therapy. The authors conclude that residual mass is commonly found in long-term follow-up after radiation therapy, that isolated imaging studies revealing such findings after treatment in no way herald a diagnosis of recurrence, and that hypopituitarism following pituitary radiation therapy does not correlate with the ablation or persistence of tissue within the sella

    Full Text Available OBJECTIVE: To examine alcohol use and subsequent HIV risky behaviors among a sample of predominately ethnic minority people living with HIV/AIDS (PLWHA in a rural community in Yunnan Province, China. METHOD: A cross-sectional study with a face-to-face questionnaire interview was conducted among eligible participants. RESULTS: In total, 455 (94.4% out of 482 eligible HIV patients participated in the study. Of them, 82.6% were ethnic minorities; 15.4% were never married; 96.5% were sexually experienced; 55.4% had used drugs, 67% were receiving antiretroviral therapy (ART. Over 65% were ever drinkers; of whom 61.5% were current drinkers. Among current drinkers, 32.4% drank daily and 41.2% were hazardous drinkers. Chinese white wine was the preferred choice. Higher level of alcohol use among drinkers in the preceding month was positively associated with being males (OR = 2.76, 95%CI: 1.03-7.43, ethnic minorities (OR Jingpo = 2.21, 95%CI: 1.06-4.59; OR other minorities = 3.20, 95%CI: 1.34-7.62, higher education (OR1-6 = 1.98, 95%CI: 0.99-3.96; OR≥7 = 2.35, 95%CI: 1.09-5.06 and being ART-naive (OR = 2.69, 95%CI: 1.67-4.32. About 39% of ever drinkers reported having engaged in sex after drinking since HIV diagnosis. Those who were younger than 46 years (OR16-25 = 7.77, 95%CI: 1.22-49.60, OR26-35 = 2.79, 95%CI: 1.06-7.35, OR36-45 = 2.96, 95%CI: 1.57-7.58, hazardous drinkers (OR = 1.99, 95%CI: 1.00-3.97 and drug users (OR = 3.01, 95%CI: 1.19-7.58 were more likely to have had sex after drinking. Approximately 56% of drug users had used drugs after drinking. CONCLUSIONS: High prevalence of alcohol use and subsequent risky behaviors including sexual engagement and drug use among HIV patients in rural Yunnan require tremendous and integrated efforts for prevention and control of alcohol and drug abuse and HIV spreading.

    2013-08-10

    Two decades after the initial gene therapy trials and more than 1700 approved clinical trials worldwide we not only have gained much new information and knowledge regarding gene therapy in general, but also learned to understand the concern that has persisted in society. Despite the setbacks gene therapy has faced, success stories have increasingly emerged. Examples for these are the positive recommendation for a gene therapy product (Glybera) by the EMA for approval in the European Union and the positive trials for the treatment of ADA deficiency, SCID-X1 and adrenoleukodystrophy. Nevertheless, our knowledge continues to grow and during the course of time more safety data has become available that helps us to develop better gene therapy approaches. Also, with the increased understanding of molecular medicine, we have been able to develop more specific and efficient gene transfer vectors which are now producing clinical results. In this review, we will take a historical view and highlight some of the milestones that had an important impact on the development of gene therapy. We will also discuss briefly the safety and ethical aspects of gene therapy and address some concerns that have been connected with gene therapy as an important therapeutic modality.

  17. Malignant pleural mesothelioma in a child

    Full Text Available Malignant pleural mesothelioma (MPM is an aggressive malignancy that occurs extremely rarely in the pediatric population. It carries a dismal prognosis. Adult studies are often used to guide therapy in the pediatric population, as a limited number of case reports form the body of pediatric literature. Herein, we document the course and treatment of an 8-year old male diagnosed with MPM. The diagnosis came after he presented to his family physician with dyspnea and was found to have a large right-sided chest mass on subsequent imaging. Through an initial right pneumonectomy and subsequent chest wall excision, followed by chemotherapy with Pemetrexed and Cisplatin he remains virtually disease free today, almost 2 years following surgery.

  20. Tumor targeted gene therapy

    Knowledge of molecular mechanisms governing malignant transformation brings new opportunities for therapeutic intervention against cancer using novel approaches. One of them is gene therapy based on the transfer of genetic material to an organism with the aim of correcting a disease. The application of gene therapy to the cancer treatment had led to the development of new experimental approaches such as suicidal gene therapy, inhibition of oncogenes and restoration of tumor-suppressor genes. Suicidal gene therapy is based on the expression in tumor cells of a gene encoding an enzyme that converts a prodrug into a toxic product. Representative suicidal genes are Herpes simplex virus type 1 thymidine kinase (HSV1-tk) and cytosine deaminase (CD). Especially, physicians and scientists of nuclear medicine field take an interest in suicidal gene therapy because they can monitor the location and magnitude, and duration of expression of HSV1-tk and CD by PET scanner
