Abstract
BACKGROUND Fluphenazine decanoate licenced as a long-acting injectable (LAI) first-generation antipsychotic (FGA) was withdrawn from sale in 2018. This study evaluates if its withdrawal resulted in increased relapse rates of psychosis in an Irish patient cohort and examines which prescribed alternative antipsychotic medications were associated with more optimal outcomes. METHODS Fifteen participants diagnosed with a psychotic disorder were included. A mirror-image study over 24-months' pre-and post-withdrawal of fluphenazine was conducted. Kaplan-Meier survival and proportional hazards analyses were conducted. The impact of alternate antipsychotic agents (LAI flupenthixol compared to other antipsychotic medications) was evaluated. Semi-structured interviews with participants examined subjective opinions regarding the change in their treatment. RESULTS Seven participants (46.7%) relapsed in the 24-month period subsequent to fluphenazine discontinuation compared to one individual (6.7%) in the previous identical time-period (p = 0.035). Flupenthixol treatment was associated with reduced relapse rates compared to other antipsychotics (χ2 = 5.402, p = 0.02). Thematic analysis revealed that participants believed that the discontinuation of fluphenazine deleteriously impacted the stability of their mental disorder. CONCLUSION The withdrawal of fluphenazine was associated with increased relapse rate in individuals previously demonstrating stability of their psychotic disorder. While acknowledging the limitation of small sample size, preliminary evidence from this study suggests that treatment with the first-generation antipsychotic (FGA) flupenthixol was associated with a lower risk of relapse compared to SGAs. Reasons for this lower risk of relapse are not fully clear but could be related to dopamine hypersensitivity with this treatment change.

Abstract
OBJECTIVES We previously demonstrated that three months into the COVID-19 pandemic, the impact on individuals with treatment-resistant psychotic disorders was modest. Here, we examined and compared the psychological and social impact of the COVID-19 pandemic on the same patient cohort 12 months after their initial study engagement. METHODS Semi-structured interviews were conducted with 54 individuals (85.7% response rate) between June 12 and July 29, 2021, 12 months after their initial interviews. Participants' subjective experience of the impact of the COVID-19 pandemic on anxiety symptoms, social and vocational functioning was measured utilising the same Likert scales at both time points. Anxiety symptoms were additionally measured using subjective (Beck Anxiety Inventory) and objective (Hamilton Anxiety Rating Scale (HARS)) psychometric instruments. Paired t-tests or Wilcoxon ranked tests compared parametric or non-parametric data over time. Free-text responses pertaining to participants' perspectives on the impact of COVID-19 were grouped into themes. RESULTS A minor increase in anxiety symptoms was demonstrated utilising the HARS (1.9 points, z = 3.017, p = 0.003), with a minimal increase in depressive symptoms noted using Likert ratings (0.8 points, z = 2.119, p = 0.034). Five themes were identified with the most prevalent being (i) positivity regarding vaccination, (ii) social isolation from family members and (iii) looking forward to post-COVID-19 'normality'. However, negative views pertaining to the psychosocial impact of COVID-19 and vaccination were additionally reported. CONCLUSIONS No significant overall clinical change in symptomatology or functioning over time was noted.The study demonstrated that positive views regarding vaccination and optimism for the future were evident for some participants.

Abstract
BACKGROUND AND PURPOSE Contrast curve truncation in CTP protocols may introduce errors. We sought to identify risk factors and design a protocol to avoid truncation while limiting radiation. MATERIALS AND METHODS In an initial fixed-timing cohort, patients underwent a 65-second CTP with 2-second delay postcontrast injection. Multivariable analysis identified factors associated with truncation. A later case-specific cohort underwent either the original protocol or a low cardiac output protocol with a 7-second delay and 75-second scanning window, with selection determined by CTA test-dose enhancement upswing delay. Time-density curves were assessed for truncation and compared between the 2 groups, and the radiation dose was evaluated. RESULTS From September 2017 through May 2018, one hundred fifty-three patients underwent the standard fixed-timing protocol. Age (OR, 1.82/10-year increase; P = .019), reduced left ventricle ejection fraction (OR, 9.23; P = .001), and hypertension (OR, 0.32; P = .06) were independently associated with truncation in an exploratory multivariable model. From May 2018 through April 2019, one hundred fifty-seven patients underwent either the standard (72 patients) or low cardiac output protocol (85 patients). The fixed-timing cohort had 15 truncations (9.8%) versus 4 in the case-specific cohort (2.5%; P = .009). If the low cardiac output protocol were applied to those with >10.6% predicted risk of truncation based on age, left ventricle ejection fraction, and hypertension, the number of truncations would have decreased from 15 to 4 in the fixed-timing cohort. CONCLUSIONS Older age, left ventricle ejection fraction, and the absence of hypertension increase the risk of time-density curve truncation. However, a CTA test-dose-directed case-specific protocol can reduce truncation to ensure accurate data while mitigating radiation dose increases.

Abstract
Few diet and physical activity evidence-based interventions have been routinely used in community settings to achieve population health outcomes. Adapting interventions to fit the implementation context is important to achieve the desired results. Harvest for Health is a home-based vegetable gardening intervention that pairs cancer survivors with certified Master Gardeners from the Cooperative Extension Service with the ultimate goal of increasing vegetable consumption and physical activity, and improving physical functioning and health-related quality-of-life. Harvest for Health has potential for widespread dissemination since Master Gardener Programs exist throughout the United States. However, state- and population-specific adaptations may be needed to improve intervention adoption by other Master Gardener Programs. Our primary objective was to adapt this evidence-informed intervention that was initially incepted in Alabama, for the drastically different climate and growing conditions of New Mexico using a recommended adaptation framework. Our secondary objective was to develop a study protocol to support a pilot test of the adapted intervention, Southwest Harvest for Health. The adaptation phase is a critical first step towards widespread dissemination, implementation, and scale-out of an evidence-based intervention. This paper describes the adaptation process and outcomes, and the resulting protocol for the ongoing pilot study that is currently following 30 cancer survivors and their paired Extension Master Gardener mentors.

Abstract
Abstract
BACKGROUND
FGFR mutations and translocations occur in approximately 10% of glioblastomas (GBMs). FGFR3-TACC3 fusion has been reported as predictive of response to FGFR tyrosine kinase inhibitor therapy both pre-clinically and clinically. Infigratinib (BGJ398) is a selective small-molecule pan-FGFR kinase inhibitor that has demonstrated anti-tumor activity in several solid tumors with FGFR genetic alterations. Therefore, we conducted a phase II trial to test the efficacy of infigratinib in FGFR-altered recurrent GBM (NCT01975701).
METHODS
This open-label trial accrued adults with recurrent high-grade gliomas following failure of initial therapy that harbored FGFR1-TACC1 or FGFR3-TACC3 fusions; activating mutations in FGFR1, 2 or 3; or FGFR1, 2, 3, or 4 amplification. Oral infigratinib was administered 125 mg on days 1–21 every 28 days. Prophylaxis for hyperphosphatemia, a common toxicity, was recommended. The primary endpoint was the 6-month progression-free survival (6mPFS) rate by RANO (locally assessed, estimated by K-M method), with a goal of >40%.
RESULTS
As of the Sep 2017 data cut-off, 26 patients (16 men, 10 women; median age 55 years, range 20–76 years; 50% with ≥2 prior regimens) were treated, and 24 (92.3%) discontinued for disease progression (n=21) or other reasons (n=3). All patients had FGFR1 or FGFR3 gene alterations, and 4 had >1 gene alteration. The estimated 6mPFS rate was 16% (95% CI 5.0–32.5%); median PFS was 1.7 months (95% CI 1.1–2.8 months); median OS was 6.7 months (95% CI 4.2–11.7 months); ORR was 7.7% (95% CI 1.0–25.1%). The best overall response was: partial response 7.7% (FGFR1 mutation n=1; FGFR3 amplification n=1); stable disease 26.9%; progressive disease 50.0%; missing/unknown 15.3%. The most common (>15%) all-grade treatment-related adverse events (AEs) were hyperphosphatemia, fatigue, diarrhea, hyperlipasemia, and stomatitis. There were no grade 4 treatment-related AEs. Eleven patients (42.3%) had treatment-related AEs requiring dose interruptions or reductions (most commonly hyperphosphatemia).
CONCLUSIONS
Infigratinib induced partial response or stable disease in approximately one-third of patients with recurrent GBM and/or other glioma subtypes harboring FGFR alterations. Most AEs were reversible and manageable. Further potential combinations are being explored in patients with proven FGFR-TACC fusion genes and analysis of biomarker data is ongoing.

Abstract
Linguistic diversity, now and in the past, is widely regarded to be independent of biological changes that took place after the emergence of Homo sapiens We show converging evidence from paleoanthropology, speech biomechanics, ethnography, and historical linguistics that labiodental sounds (such as "f" and "v") were innovated after the Neolithic. Changes in diet attributable to food-processing technologies modified the human bite from an edge-to-edge configuration to one that preserves adolescent overbite and overjet into adulthood. This change favored the emergence and maintenance of labiodentals. Our findings suggest that language is shaped not only by the contingencies of its history, but also by culturally induced changes in human biology.

Abstract
BACKGROUND We report longitudinal health-related quality-of-life (HRQoL) data from the international, randomized, double-blind, placebo-controlled phase III ExteNET study, which demonstrated an invasive disease-free survival benefit of extended adjuvant therapy with neratinib over placebo in human epidermal growth factor receptor-2-positive early-stage breast cancer. PATIENTS AND METHODS Women (N = 2840) with early-stage HER2-positive breast cancer who had completed trastuzumab-based adjuvant therapy were randomly assigned to neratinib 240 mg/day or placebo for 12 months. HRQoL was an exploratory end point. Patients completed the Functional Assessment of Cancer Therapy-Breast (FACT-B) and EuroQol 5-Dimensions (EQ-5D) questionnaires at baseline and months 1, 3, 6, 9, and 12. Changes from baseline were compared using analysis of covariance with no imputation for missing values. Sensitivity analyses used alternative methods. Changes in HRQoL scores were regarded as clinically meaningful if they exceeded previously reported important differences (IDs). RESULTS Of the 2840 patients (intention-to-treat population), 2407 patients were evaluable for FACT-B (neratinib, N = 1171; placebo, N = 1236) and 2427 patients for EQ-5D (neratinib, N = 1186; placebo, N = 1241). Questionnaire completion rates exceeded 85%. Neratinib was associated with a decrease in global HRQoL scores at month 1 compared with placebo (adjusted mean differences: FACT-B total, -2.9 points; EQ-5D index, -0.02), after which between-group differences diminished at later time-points. Except for the FACT-B physical well-being (PWB) subscale at month 1; all between-group differences were less than reported IDs. The FACT-B breast cancer-specific subscale showed small improvements with neratinib at months 3-9, but all were less than IDs. Sensitivity analyses exploring missing data did not change the results. CONCLUSIONS Extended adjuvant neratinib was associated with a transient, reversible decrease in HRQoL during the first month of treatment, possibly linked to treatment-related diarrhea. With the exception of the PWB subscale at month 1, all neratinib-related HRQoL changes did not reach clinically meaningful thresholds. ClinicalTrials.gov: NCT00878709.

Abstract
Linguistic diversity, now and in the past, is widely regarded to be independent of biological changes that took place after the emergence of Homo sapiens We show converging evidence from paleoanthropology, speech biomechanics, ethnography, and historical linguistics that labiodental sounds (such as "f" and "v") were innovated after the Neolithic. Changes in diet attributable to food-processing technologies modified the human bite from an edge-to-edge configuration to one that preserves adolescent overbite and overjet into adulthood. This change favored the emergence and maintenance of labiodentals. Our findings suggest that language is shaped not only by the contingencies of its history, but also by culturally induced changes in human biology.

Abstract
Breast cancer-associated fibroblasts (CAFs) have a crucial role in tumor initiation, metastasis and therapeutic resistance by secreting various growth factors, cytokines, protease and extracellular matrix components. Soluble factors secreted by CAFs are involved in many pathways including inflammation, metabolism, proliferation and epigenetic modulation, suggesting that CAF-dependent reprograming of cancer cells affects a large set of genes. This paracrine signaling has an important role in tumor progression, thus deciphering some of these processes could lead to relevant discoveries with subsequent clinical implications. Here, we investigated the mechanisms underlying the changes in gene expression patterns associated with the cross-talk between breast cancer cells and the stroma. From RNAseq data obtained from breast cancer cell lines grown in presence of CAF-secreted factors, we identified 372 upregulated genes, exhibiting an expression level positively correlated with the stromal content of breast cancer specimens. Furthermore, we observed that gene expression changes were not mediated through significant DNA methylation changes. Nevertheless, CAF-secreted factors but also stromal content of the tumors remarkably activated specific genes characterized by a DNA methylation pattern: hypermethylation at transcription start site and shore regions. Experimental approaches (inhibition of DNA methylation, knockdown of methyl-CpG-binding domain protein 2 and chromatin immunoprecipitation assays) indicated that this set of genes was epigenetically controlled. These data elucidate the importance of epigenetics marks in the cancer cell reprogramming induced by stromal cell and indicated that the interpreters of the DNA methylation signal have a major role in the response of the cancer cells to the microenvironment.

Abstract
Innate lymphocyte populations, such as innate lymphoid cells (ILCs), γδ T cells, invariant natural killer T (iNK T) cells and mucosal-associated invariant T (MAIT) cells are emerging as important effectors of innate immunity and are involved in various inflammatory and autoimmune diseases. The aim of this study was to assess the frequencies and absolute numbers of innate lymphocytes as well as conventional lymphocytes and monocytes in peripheral blood from a cohort of anti-neutrophil cytoplasm autoantibody (ANCA)-associated vasculitis (AAV) patients. Thirty-eight AAV patients and 24 healthy and disease controls were included in the study. Patients with AAV were sampled both with and without immunosuppressive treatment, and in the setting of both active disease and remission. The frequencies of MAIT and ILC2 cells were significantly lower in patients with AAV and in the disease control group compared to healthy controls. These reductions in the AAV patients remained during remission. B cell count and frequencies were significantly lower in AAV in remission compared to patients with active disease and disease controls. Despite the strong T helper type 2 (Th) preponderance of eosinophilic granulomatosis with polyangiitis, we did not observe increased ILC2 frequency in this cohort of patients. The frequencies of other cell types were similar in all groups studied. Reductions in circulating ILC2 and MAIT cells reported previously in patients with AAV are not specific for AAV, but are more likely to be due to non-specific manifestations of renal impairment and chronic illness. Reduction in B cell numbers in AAV patients experiencing remission is probably therapy-related.

Abstract
PurposeFungal keratitis is relatively rare in temperate climates with only one previous population-based study, which reported a minimum annual incidence of 0.32 per million population in the United Kingdom. We performed a nationwide study in the Republic of Ireland of cases over a 6-year period to establish the incidence, risk factors, treatment, and outcomes of fungal keratitis.Patients and methodsAll corneal scraping specimens positive for fungal species over a 6-year period were identified at the microbiology departments of the seven main ophthalmology units in the Republic of Ireland. Census data was used to establish national minimum annual incidence.ResultsForty-two eyes were treated for confirmed fungal keratitis during the 6-year period. This resulted in a minimum incidence of 1.53 cases per million population per year. Twenty-eight of 42 cases (67%) were due to filamentary fungi, with the most common species being Aspergillus. Pre-existing ocular surface disease was the most common risk factor constituting 42.9%; 26.2% underwent keratoplasty. No eyes underwent evisceration. Two eyes resulted in a level of vision of no perception of light. The mean LogMAR acuity in the remainder of cases was 0.89 with a range from -0.10 to 4.00.ConclusionThis study demonstrates a much higher minimum annual incidence than previously reported. The causative organism is highly related to risk factor. The range of visual outcomes remains broad in all subgroups. The wide range of outcomes and treatments used highlights the need for better evidence-based guidelines for fungal keratitis.

Abstract
Components of the SWI/SNF chromatin remodeling complex, including BRG1 (also SMARCA4), are inactivated in cancer. Among other functions, SWI/SNF orchestrates the response to retinoid acid (RA) and glucocorticoids (GC) involving downregulation of MYC. The epigenetic drugs SAHA and azacytidine, as well as RA and GC, are currently being used to treat some malignancies but their therapeutic potential in lung cancer is not well established. Here we aimed to determine the possible therapeutic effects of azacytidine and SAHA (A/S) alone or in combination with GC plus RA (GC/RA) in lung cancers with either BRG1 inactivation or MYC amplification. In vitro, responses to GC/RA treatment were more effective in MYC-amplified cells. These effects were mediated by BRG1 and involved a reprogramming towards prodifferentiation gene expression signatures and downregulation of MYC. In MYC-amplified cells, administration of GC/RA enhanced the cell growth inhibitory effects of A/S which, in turn, accentuated the prodifferentiation features promoted by GC/RA. Finally, these treatments improved overall survival of mice orthotopically implanted with MYC-amplified, but not BRG1-mutant, cells and reduced tumor cell viability and proliferation. We propose that the combination of epigenetic treatments with retinoids and corticoids of MYC-driven lung tumors constitute a strategy for therapeutic intervention in this otherwise incurable disease.

Abstract
OBJECTIVE The development of effective therapies for cartilage protection has been limited by a lack of efficient quantitative cartilage imaging modalities in pre-clinical in vivo models. Our objectives were two-fold: first, to validate a new contrast-enhanced 3D imaging analysis technique, equilibrium partitioning of an ionic contrast agent-micro computed tomography (EPIC-μCT), in a rat medial meniscal transection (MMT) osteoarthritis (OA) model; and second, to quantitatively assess the sensitivity of EPIC-μCT to detect the effects of matrix metalloproteinase inhibitor (MMPi) therapy on cartilage degeneration. METHODS Rats underwent MMT surgery and tissues were harvested at 1, 2, and 3 weeks post-surgery or rats received an MMPi or vehicle treatment and tissues harvested 3 weeks post-surgery. Parameters of disease progression were evaluated using histopathology and EPIC-μCT. Correlations and power analyses were performed to compare the techniques. RESULTS EPIC-μCT was shown to provide simultaneous 3D quantification of multiple parameters, including cartilage degeneration and osteophyte formation. In MMT animals treated with MMPi, OA progression was attenuated, as measured by 3D parameters such as lesion volume and osteophyte size. A post-hoc power analysis showed that 3D parameters for EPIC-μCT were more sensitive than 2D parameters requiring fewer animals to detect a therapeutic effect of MMPi. 2D parameters were comparable between EPIC-μCT and histopathology. CONCLUSION This study demonstrated that EPIC-μCT has high sensitivity to provide 3D structural and compositional measurements of cartilage and bone in the joint. EPIC-μCT can be used in combination with histology to provide a comprehensive analysis to screen new potential therapies.

Abstract
The introduction of new therapies against particular genetic mutations in non-small-cell lung cancer is a promising avenue for improving patient survival, but the target population is small. There is a need to discover new potential actionable genetic lesions, to which end, non-conventional cancer pathways, such as RNA editing, are worth exploring. Herein we show that the adenosine-to-inosine editing enzyme ADAR1 undergoes gene amplification in non-small cancer cell lines and primary tumors in association with higher levels of the corresponding mRNA and protein. From a growth and invasion standpoint, the depletion of ADAR1 expression in amplified cells reduces their tumorigenic potential in cell culture and mouse models, whereas its overexpression has the opposite effects. From a functional perspective, ADAR1 overexpression enhances the editing frequencies of target transcripts such as NEIL1 and miR-381. In the clinical setting, patients with early-stage lung cancer, but harboring ADAR1 gene amplification, have poor outcomes. Overall, our results indicate a role for ADAR1 as a lung cancer oncogene undergoing gene amplification-associated activation that affects downstream RNA editing patterns and patient prognosis.

Abstract
Close to half of de novo acute myeloid leukemia (AML) cases do not exhibit any cytogenetic aberrations. In this regard, distortion of the DNA methylation setting and the presence of mutations in epigenetic modifier genes can also be molecular drivers of the disease. In recent years, somatic missense mutations of the DNA methyltransferase 3A (DNMT3A) have been reported in ~20% of AML patients; however, no obvious critical downstream gene has been identified that could explain the role of DNMT3A in the natural history of AML. Herein, using whole-genome bisulfite sequencing and DNA methylation microarrays, we have identified a key gene undergoing promoter hypomethylation-associated transcriptional reactivation in DNMT3 mutant patients, the leukemogenic HOX cofactor MEIS1. Our results indicate that, in the absence of mixed lineage leukemia fusions, an alternative pathway for engaging an oncogenic MEIS1-dependent transcriptional program can be mediated by DNMT3A mutations.

Abstract
OBJECTIVE Current histological scoring methods to evaluate efficacy of potential therapeutics for slowing or preventing joint degeneration are time-consuming and semi-quantitative in nature. Hence, there is a need to develop and standardize quantitative outcome measures to define sensitive metrics for studying potential therapeutics. The objectives of this study were to use equilibrium partitioning of an ionic contrast agent via Equilibrium Partitioning of an Ionic Contrast-Microcomputed tomography (EPIC-μCT) to quantitatively characterize morphological and compositional changes in the tibial articular cartilage in two distinct models of joint degeneration and define localized regions of interest to detect degenerative cartilage changes. MATERIALS AND METHODS The monosodium iodoacetate (MIA) and medial meniscal transection (MMT) rat models were used in this study. Three weeks post-surgery, tibiae were analyzed using EPIC-μCT and histology. EPIC-μCT allowed measurement of 3D morphological changes in cartilage thickness, volume and composition. RESULTS Extensive cartilage degeneration was observed throughout the joint in the MIA model after 3 weeks. In contrast, the MMT model showed more localized degeneration with regional thickening of the medial tibial plateau and a decrease in attenuation consistent with proteoglycan (PG) depletion. Focal lesions were also observed and 3D volume calculated as an additional outcome metric. CONCLUSIONS EPIC-μCT was used to quantitatively assess joint degeneration in two distinct preclinical models. The MMT model showed similar features to human Osteoarthritis (OA), including localized lesion formation and PG loss, while the MIA model displayed extensive cartilage degeneration throughout the joint. EPIC-μCT imaging provides a rapid and quantitative screening tool for preclinical evaluation of OA therapeutics.

Abstract
Disruption of the histone modification patterns is one of the most common features of human tumors. However, few genetic alterations in the histone modifier genes have been described in tumorigenesis. Herein we show that the histone methyltransferase SETDB1 undergoes gene amplification in non-small and small lung cancer cell lines and primary tumors. The existence of additional copies of the SETDB1 gene in these transformed cells is associated with higher levels of the corresponding mRNA and protein. From a functional standpoint, the depletion of SETDB1 expression in amplified cells reduces cancer growth in cell culture and nude mice models, whereas its overexpression increases the tumor invasiveness. The increased gene dosage of SETDB1 is also associated with enhanced sensitivity to the growth inhibitory effect mediated by the SETDB1-interfering drug mithramycin. Overall, the findings identify SETDB1 as a bona fide oncogene undergoing gene amplification-associated activation in lung cancer and suggest its potential for new therapeutic strategies.

Abstract
OBJECTIVE To report the long-term safety and efficacy results from CAMMS223 comparing alemtuzumab with interferon β-1a in early, active relapsing-remitting multiple sclerosis (RRMS). What are the long-term effects of alemtuzumab treatment, received 36 to 48 months previously, on relapse and disability in early, active RRMS? This study provides evidence of the effectiveness of alemtuzumab in reducing the relapse rate and accumulation of disability compared with interferon β-1a (IFNβ-1a) through extended follow-up (up to 60 months from baseline). METHODS Of 334 patients originally randomized, 198 participated in the extension phase (151 [68%] alemtuzumab and 47 [42%] IFNβ-1a). Disability, relapses, and safety were assessed as in the original study period. Efficacy outcomes were analyzed from baseline of the original trial period to 60 months. Safety data extended beyond 60 months. RESULTS Over 5 years, alemtuzumab lowered the risk of sustained accumulation of disability by 72% and the rate of relapse by 69% compared with IFNβ-1a (both p < 0.0001). The annualized relapse rate from baseline to month 60 was 0.11 for alemtuzumab and 0.35 for IFNβ-1a. Complete safety follow-up reflected 988 and 376 person-years for alemtuzumab and IFNβ-1a patients, respectively. Serious infections were seen in 7% of alemtuzumab patients and 3% of IFNβ-1a patients, and thyroid disorders were seen in 30% of alemtuzumab patients vs 4% of IFNβ-1a patients. Immune thrombocytopenia occurred in 3% of alemtuzumab patients and 0.9% of IFNβ-1a patients during the initial study period; no additional events were reported during the extension phase. One alemtuzumab patient developed Goodpasture disease 39 months after the second annual cycle of alemtuzumab. CONCLUSIONS Through extended follow-up, alemtuzumab remained significantly more efficacious than IFNβ-1a, with a safety profile consistent with previous reports. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that alemtuzumab is more effective than interferon β-1a in reducing relapses and disability in patients with RRMS in a long-term follow-up of a rater-blinded, randomized clinical trial with 59.5% of patients participating in the extended follow-up period.

Abstract
BACKGROUND The American Society of Bariatric Surgery has initiated a Bariatric Surgery Center of Excellence Program and the American College of Surgeons has followed with their Bariatric Surgery Center Network Accreditation Program. These programs postulate that concentration of weight loss operations in high-volume centers will decrease surgical mortality and improve outcomes. METHODS The purpose of this study was to calculate the in-hospital mortality for bariatric operations accomplished at the highest volume bariatric surgery center in the state of New Jersey. After receiving Institutional Revew Board approval, the revised surgical schedule was used to identify all patients undergoing weight loss surgery (WLS) at Hackensack University Medical Center from 1998 through June, 2006. Data for these patients were then harvested from the hospital's electronic medical record. Step-wise and univariate logistic regression analysis tested the impact of various factors on hospital length of stay and in-hospital mortality. RESULTS Between 1998 and June, 2006, 5,365 patients underwent WLS surgery: 2,099 open vertical banded gastroplasty-Roux en Y gastric bypass (VBG-RYGB); 2,177 laparoscopic Roux en Y gastric bypass (LRYGB); and 1,089 laparoscopic adjustable gastric banding (LAGB). 75.5% of patients were women. Median age was 41 years old (13-79), median weight 128 kg (81.2-290.3), and median body mass index 46.1 kg/m2 (35.0-92.6). Median total operating room time for VBG-RYGB was 115 min (33-328); LRYGB 155 min (53-493), and LAGB 92 min (33-274). Median length of stay for VBG-RYGB was 3 days (1-39 days), LRYGB 2 days (1-46 days), and LAGB 1 day (1-20). Seven patients died in hospital after the 5,365 WLS operations (0.13%): four after VBG-RYGB (0.19%); three after LRYGB (0.14%); and none after LAGB (0%). The characteristics of the patients who died did not significantly differ from the group as a whole. CONCLUSION Surgeons at Hackensack University Medical Center, a high volume, accredited 1A American College of Surgeons Bariatric Surgery Center, achieved a 0.13% mortality among 5,365 patients undergoing weight loss operations between 1998 and June, 2006. This study supports the concept that high-volume centers perform bariatric operations with low mortalities.

Abstract
Astragaloside IV, a natural product purified from the Chinese medical herb Astragalus membranaceus (Fisch) Bge, is now being developed as a cardioprotective agent for treating cardiovascular diseases. The purpose of the present study was to examine in vivo pharmacokinetics and tissue distribution in both rats and dogs by using an established high-performance liquid chromatography (HPLC) coupled with tandem mass spectrometry quantitative detection method. Astragaloside IV showed moderate to fast elimination; the elimination half-life of astragaloside IV was 98.1, 67.2 and 71.8 min in male rats, and 34.0, 66.9 and 131.6 min in female rats at doses of 0.75, 1.5 and 3.0 mg/kg, respectively. There was no significant difference in systemic clearance at three dose levels, suggesting that astragaloside IV may have linear pharmacokinetic characteristics in rats within the dose ranges tested. The highest concentration of astragaloside IV was detected in the lung and liver. However, limited distribution to the brain, indicates that astragaloside IV may have difficulty penetrating the blood brain barrier. In addition, only about 50% of the parent astragaloside IV was recovered in both urine and feces. These results indicate that there was about 83% astragaloside IV binding to plasma protein and that the binding to the plasma is linear at the concentration range of 250-1000 ng/ml. As in rats, astragaloside IV may have linear pharmacokinetic characteristics in dogs within the dose ranges tested. Astragaloside IV was slowly cleared via hepatic clearance with a systemic clearance (CL) of about 0.004 l/kg/min. Based on the favorable pharmacokinetic properties in both rats and dogs, astragaloside IV warrants further investigation for the prevention of cardiovascular diseases.

Abstract
The objective of this study was to evaluate the safety, tolerability, maximum tolerated dose, pharmacokinetics, and pharmacodynamics of five fixed doses of ganstigmine (CHF 2819) in patients with probable Alzheimer's disease (AD). This randomized, double-blind, placebo-controlled trial evaluated five dose levels (5, 7.5, 10, 12.5, and 15 mg) administered orally once daily for 7 days. Adverse events and continuous telemetry were collected on successive panels of six patients (five active, one placebo). Acetylcholinesterase, butyrylcholinesterase, and plasma drug levels were measured. A total of 29 patients were randomized and 18 completed the study. A total of seven patients, including five of five in the 12.5-mg panel, discontinued because of adverse events. Four patients were withdrawn administratively from the first panel while an episode of atrial fibrillation (the only serious adverse event) was investigated. This panel was then repeated. Mild, transient headache or nausea were the most commonly reported adverse events. Multiple moderate adverse events in the 12.5-mg panel (including nausea, vomiting, and anorexia) led to the decision not to proceed with a 15-mg panel. Ten milligrams was determined to be the maximum tolerated dose. Ganstigmine exhibited nonlinear pharmacokinetics, was absorbed rapidly, and reached peak concentrations within 1 hour. Acetylcholinesterase inhibition was dose dependent and lasted as long as 24 hours. Ganstigmine, a novel cholinesterase inhibitor, was well tolerated within a dosing range of 5 to 10 mg. Once-daily dosing is supported by data on acetylcholinesterase inhibition.

Abstract
Forty-eight patients with myelodysplastic syndromes and a platelet count greater than 80 x 10(9)/L were the subjects of a study of platelet function. A whole-blood platelet lumi-aggregometer was used for simultaneous measurement of platelet aggregation by the impedance method and of adenosine triphosphate-dense granule release. The results were correlated with skin bleeding time and episodes of clinical bleeding or thrombosis. Thirty-five patients had at least 1 abnormal result indicating platelet hypoactivity; 7 patients had mixed platelet hypoactivity and hyperactivity; and 4 patients had platelet hyperactivity. Only 2 patients had normal results. There was good correlation between platelet hypoactivity and prolonged skin bleeding time (P = .005); however, several patients with platelet hypoactivity had normal skin bleeding times. This finding suggested that whole-blood platelet aggregation studies may be more sensitive than bleeding time in identification of patients at risk of bleeding. Clinical hemorrhage was frequent (32 patients) in this cohort despite platelet counts greater than 100 x 10(9)/L. This finding indicated platelet hypofunction was clinically important. In contrast, only 2 of the 13 patients with thrombotic events had evidence of platelet hyperactivity, suggesting that other clinical factors are probably more important determinants of thrombosis. These observations confirm that platelet dysfunction is common in patients with myelodysplastic syndromes and suggest a useful role for routine whole-blood platelet aggregation studies to identify patients at risk of bleeding.
