Abstract
Reproductive cycling in fattening gilts can be associated with undesirable effects, such as estrus-related aggressive behavior, reduced feed intake and, in production systems where gilts are co-housed with entire males, unwanted pregnancy. Immunization against Gonadotrophin Releasing Factor (IM) can temporarily suppress ovarian activity, including related negative consequences on animal welfare and productivity. Feed intake has been shown to be higher after IM, resulting in both increased growth and increased carcass fat. A series of studies was conducted to confirm these effects on production and look at their dynamics over time. Three trials were performed to a similar design, each involving 240 gilts divided into 4 experimental groups at 12 weeks of age. One group remained untreated while the others had the two dose, IM course completed 8, 6 or 4 weeks before harvest, which was on a single day at 24, 25 or 26 weeks of age depending on the study. Feed intake was measured daily and bodyweight weekly, allowing growth parameters to be calculated on a weekly basis and for specific longer periods. Carcass weight, backfat depth and lean meat percentage were recorded at harvest. No effects were observed before the second application of the immunological product (V2) and completion of the IM course. Starting in the second week after V2 all IM groups showed a marked and consistent increase in Average Daily Feed Intake (ADFI), typically peaking at over 120% of the control group 3 to 4 weeks after V2 and then slowly declining, but still remaining elevated at 8 weeks. Weekly Average Daily Gain (ADG) showed a similar pattern but with a faster decline, resulting in the initially favorable impact on feed efficiency becoming less favorable as the V2 to harvest interval (V2H) progressed. Carcass weights were higher in IM gilts and backfat depths were greater, with the effects increasing with increasing V2H. Correspondingly, carcass lean meat percentage tended to decrease, although the higher carcass weights meant that the absolute weight of lean meat remained similar or higher. Carcass yield was generally unaffected by IM, but some between-group differences were statistically significant, and it is possible that different factors predominated at different times after V2, creating a complex relationship with V2H duration. The optimum IM protocol will depend on local conditions and production objectives but, as a generalization and assuming ad libitum feeding, a shorter V2H will favor efficient growth, while a longer duration will maximize carcass changes, such as increased fat coverage. It is suggested that the growth performance changes seen after IM in gilts might be viewed as a process of adjustment to a heavier and fatter target body type.

Abstract
Aim: To assess associations between relapses and psychosocial outcomes in adult patients with schizophrenia treated in United States (US) healthcare settings. Methods: Data were derived from a point-in-time survey of psychiatrists and their patients with schizophrenia conducted across the US, France, Spain, China, and Japan between July and October 2019. For the purposes of this analysis, only data from US practitioners and patients were included. Disease-specific programmes (DSPs) are large surveys with a validated methodology conducted in clinical practise; they describe current disease management, disease burden, and associated treatment effects (clinical and physician-perceived). Participating psychiatrists completed patient record forms for their next 10 consecutive adult consulting patients with schizophrenia, with the same patients invited to voluntarily complete a patient self-completion (PSC) questionnaire. Surveys contained questions on the patients' disease background, treatment history, prior hospitalisation due to schizophrenia relapse and a series of psychosocial outcomes. Associations between relapses in the last 12 months and psychosocial outcomes were examined using multiple regression. Results: A total of 124 psychiatrists provided data on 1,204 patients. Of these, 469 patients (mean age, 39.6 years; 56.5% male) had known hospitalisation history for the last 12 months and completed a PSC; 116 (24.7%) patients had ≥1 relapse. Compared to patients without relapses, patients who relapsed were more likely to be homeless, unemployed, previously incarcerated, and currently have difficulties living independently (all p < 0.05). Patients who experience a relapse also had greater working impairment and poorer quality of life compared with those who did not relapse. In general, psychosocial outcomes became poorer with an increasing number of relapses. Conclusions: In this population of patients with schizophrenia from the US, relapse was significantly associated with poor psychosocial outcomes, with a greater number of relapses predicting worse outcomes. Early intervention to reduce the risk of relapse may improve psychosocial outcomes in patients with schizophrenia.

Abstract
Background: Diabetes-related distress is common among persons affected by diabetes and is associated with suboptimal glycemic control and complications, thus constituting a relevant patient-report outcome (PRO). Improving glycemic control may reduce diabetes distress and improve treatment satisfaction. This post hoc analysis evaluated PRO data for a pooled cohort of adults with type 1 diabetes (T1D) receiving sotagliflozin as adjunct to optimized insulin in the inTandem1 and inTandem2 studies. Methods: Clinically meaningful changes in the Diabetes Treatment Satisfaction Questionnaire status version (DTSQs) and the two-item Diabetes Distress Scale (DDS2) total and individual scores were examined in the pooled data from the first 24 weeks of the studies. Results: In the cohort of patients with a baseline DTSQs total score ≤32 (∼76% of entire cohort), nearly twice as many patients treated with sotagliflozin 200 (45.9%) or 400 mg (42.3%) experienced a >3-point improvement from baseline versus those treated with placebo (24%). Treatment with sotagliflozin led to statistically significant (P < 0.05) improvements across all DTSQs items. Approximately 42% of all patients were considered to have a high risk of diabetes distress (total DDS2 score ≥6) at baseline following insulin optimization. More patients shifted from high to low risk with sotagliflozin compared with placebo (∼40% vs. 23%; P ≤ 0.0002). The baseline-adjusted difference in DDS2 from placebo was significantly (P < 0.001) reduced by -0.5 and -0.6 for sotagliflozin 200 and 400 mg, respectively. Conclusions: Patients with T1D treated with sotagliflozin in addition to optimized insulin therapy reported meaningful improvements in treatment satisfaction and diabetes distress. NCT02384941 and NCT02421510.

Abstract
BACKGROUND Long-acting injectable (LAI) antipsychotics, compared with oral antipsychotics (OA), have been found to significantly improve patient outcomes, including reduced hospitalizations and emergency room (ER) admissions and increased medication adherence among adult patients with schizophrenia. In turn, the clinical benefits achieved may translate into lower economic burden. Real-world evidence of the comparative effectiveness of LAI is needed to understand the potential benefits of LAI outside of the context of clinical trials. This study aimed to provide a comprehensive synthesis of recent published real-world studies comparing healthcare utilization, costs, and adherence between patients with schizophrenia treated with LAI versus OA in the United States. METHODS In this systematic literature review, MEDLINE® was searched for peer-reviewed, real-world studies (i.e., retrospective or pragmatic designs) published in English between January 1, 2010 and February 10, 2020. Comparative studies reporting hospitalizations, ER admissions, healthcare costs, or medication adherence (measured by proportion of days covered [PDC]) in adults with schizophrenia treated with LAI versus OA (or pre- vs post-LAI initiation) in the United States were retained. Random effects meta-analyses were conducted among eligible studies to evaluate the association of LAI versus OA use on hospitalizations, ER admissions, healthcare costs, and treatment adherence. A sensitivity analysis among the subset of studies that compared OA with paliperidone palmitate once monthly (PP1M), specifically, was conducted. RESULTS A total of 1083 articles were identified by the electronic literature search, and two publications were manually added subsequently. Among the 57 publications meeting the inclusion criteria, 25 provided sufficient information for inclusion in the meta-analyses. Compared with patients treated with OA, patients initiated on LAI had lower odds of hospitalization (odds ratio [OR] 0.62, 95% confidence interval [CI] 0.54-0.71, n = 7), fewer hospitalizations (incidence rate ratio [IRR] [95% CI] 0.75 [0.65-0.88], n = 9), and fewer ER admissions (IRR [95% CI] 0.86 [0.77-0.97], n = 6). The initiation of LAI was associated with higher per-patient-per-year (PPPY) pharmacy costs (mean difference [MD] [95% CI] $5603 [3799-7407], n = 6), which was offset by lower PPPY medical costs (MD [95% CI] - $5404 [- 7745 to - 3064], n = 6), resulting in no significant net difference in PPPY total all-cause healthcare costs between patients treated with LAI and those treated with OA (MD [95% CI] $327 [- 1565 to 2219], n = 7). Patients initiated on LAI also had higher odds of being adherent to their medication (PDC ≥ 80%; OR [95% CI] 1.89 [1.52-2.35], n = 9). A sensitivity analysis on a subset of publications evaluating PP1M found results similar to those of the main analysis conducted at the LAI class level. CONCLUSIONS Based on multiple studies with varying sub-types of patient populations with schizophrenia in the United States published in the last decade, this meta-analysis demonstrated that LAI antipsychotics were associated with improved medication adherence and significant clinical benefit such as reduced hospitalizations and ER admissions compared with OA. The lower medical costs offset the higher pharmacy costs, resulting in a non-significant difference in total healthcare costs. Taken together, these findings provide strong evidence on the clinical and economic benefits of LAI compared with OA for the treatment of schizophrenia in the real world.

Abstract
Abstract
Background
Recurrent pericarditis (RP) is characterized by recurrence of symptoms of pericarditis after the original episode has ceased for 4–6 weeks. Though RP is associated with significant morbidity, there is little information regarding the impact of RP on patients' health-related quality of life (HRQOL).
Purpose
To describe clinical characteristics of and HRQOL burden in patients with RP in the United States.
Methods
An IRB-approved web-based survey was conducted among patients ≥18 years old with RP who experienced ≥1 recurrence during the prior 12 months. Respondents were recruited from the RHAPSODY clinical trial recruitment database. Patients who met the survey inclusion criteria were asked to provide information on their demographic/clinical characteristics, treatments for RP, and to complete an 11-point pericarditis pain numerical rating scale, the Patient Global Impression of Pericarditis Severity scale, the Patient-Reported Outcomes Measurement Information System® (PROMIS®) Global Health and Sleep Disturbance scales, and questions about the impact of RP on daily life.
Results
Of the 83 respondents with RP included in the study, 25% responded while experiencing a recurrence. Most respondents were Caucasian (76%) and 55% were female, with mean (standard deviation [SD]) age of 49.3 (13.7) years. Patients frequently reported history of hypertension (39%), anxiety (37%), and depression (34%); 16% and 15% of patients reported having pre-existing autoimmune disease and diabetes, respectively. About half (49%) of patients reported ≥3 recurrences in the prior year, and 40% visited the ER and 25% were hospitalized for their most recent recurrence. Among patients not actively experiencing a recurrence, 37% reported that the duration of their prior episode lasted ≥8 days. Medications most frequently used for RP and pain in the prior year included non-steroidal anti-inflammatory drugs (82%), colchicine (63%), and corticosteroids (29%). Commonly reported symptoms included chest pain (93%), shortness of breath (66%), weakness/fatigue (64%), and heart palpitations (52%). Two-thirds of patients rated the severity of symptoms during the most recent RP episode as moderately severe to very severe, and 48% reported “quite a bit” or “very much” fear of pericarditis recurrence. The mean (SD) value for worst pericarditis pain (0–10 scale) during the recent recurrence was 6.1 (2.3), with 48% reporting severe pain (≥7 on the scale). Patients had substantially worse mean [SD] T scores for PROMIS physical health (37.6 [8.6]), mental health (42.8 [9.9]), and sleep disturbance (60.6 [8.3]) than the general population (50 [10]).
Conclusions
RP is a burden on the daily lives of patients, resulting in severe pain and impaired quality-of-life including poor physical and mental health, sleep disturbance, and fear of recurrence. This study demonstrates the unmet need for therapies that can rapidly resolve symptoms and prevent recurrences.

Abstract
Abstract
Background
The EnSite Precision™ Cardiac Mapping System is a catheter navigation and mapping system capable of displaying the three-dimensional (3D) position of conventional and sensor enabled electrophysiology catheters, as well as displaying cardiac electrical activity as waveform traces and dynamic 3-D maps of cardiac chambers.
Objective
The EnSite Precision™ Observational Study was designed to quantify and characterize the use of the EnSite Precision™ Cardiac Mapping System for mapping and ablation of cardiac arrhythmias in a real-world environment and to evaluate procedural and subsequent clinical outcomes.
Methods
1065 patients were enrolled at 38 centers in the U.S. and Canada between 2017–2018. Eligible subjects were adults undergoing a cardiac electrophysiology mapping and radiofrequency ablation procedures using the EnSite Precision™ System.
Results
Of 989 patients who completed the protocol, a geometry was created in 936 (94.7%). Most initial maps were created using Automap (n=545, 67.0%) or a combination of Automap and manually mapping (n=151, 18.6%). Median time to create an initial map was 9.0 min (IQR 5.0–15.0), with a median number of used mapping points per minute of 92.7 (IQR 30.0–192.0). During ablation, AutoMark was used in 817 (82.6%) of procedures. The most frequent metrics for lesion color were Impedance Drop or Impedance Drop Percent (45.5% combined), time (23.9%) and average force (14.2%). At Canadian sites where LSI was an option, it was used as the color metric in 87 (45.8%) of cases (10.6% overall). The EnSite System was stable throughout 79.7% (n=788 of 989) of procedures. Factors affecting stability were respiratory change (n=88 of 989, 8.9%), patient movement (n=73, 7.4%), CS Positional Reference dislodgement (n=32, 3.2%), and cardioversion (n=19, 1.9%). Conscious sedation was used in 189 (19.1%) of patients. Acute success was reached based on the pre-defined endpoints for the procedure in 97.4% (n=963) of cases.
Conclusion
In a real-world study analysis, the EnSite Precision™ mapping system was associated with a high prevalence of acute procedural success, low mapping times, and high system stability.

Abstract
OBJECTIVE Recently, long non-coding ribonucleic acids (lncRNAs) have attracted more attention for their roles in tumor progression. The aim of this study was to investigate the exact role of lncRNA MIAT in the progression of non-small cell lung cancer (NSCLC) and to explore the possible underlying mechanism. PATIENTS AND METHODS MIAT expression in NSCLC tissue samples was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The association between the expression of MIAT and the prognosis of NSCLC patients were explored. Furthermore, the wound healing assay and the transwell assay were conducted in vitro. In addition, the luciferase assay and the RNA immunoprecipitation assay (RIP) were used to elucidate the underlying mechanism. RESULTS The MIAT expression in NSCLC tissues was significantly higher than that of the corresponding normal tissues. Meanwhile, the MIAT expression was associated with the overall survival time of NSCLC patients. The migration and invasion of cells were significantly promoted after MIAT was over-expressed in vitro. Meanwhile, the cell migration and cell invasion were obviously remarkedly inhibited after MIAT knock-down in vitro. Bioinformatics analysis predicted that microRNA-1246 (miR-1246) was as a novel target for MIAT. The expression of miR-1246 was significantly down-regulated or up-regulated after the overexpression or down-expression of MIAT, respectively. Further mechanism assays showed that miR-1246 was a direct target of MIAT in NSCLC. CONCLUSIONS MIAT enhanced the NSCLC cell migration and invasion via targeting miR-1246, which might be a potential biomarker in NSCLC.

Abstract
Background:The optimal methotrexate (MTX) dose is defined as 0.3mg/kg/week or ≥ 20mg/week at 6 months. [1] Considering average weight of Chinese, [2] the optimal MTX should be >15mg/w. However, not more than 30% in 25191 RA cases ever had MTX treatment in CREDIT (Chinese Registry of Rheumatoid arthritis). [3] The biggest concern is side effects of MTX. Our study is to investigate whether increasing MTX would get better results accompanied with more side effects to Chinese people.Objectives:Hakka people have the purest genes of the majority people-Han in China. It is planned to recruit 160 RA patients in Meizhou, where is a gathering place of Hakka people.Methods:The RA volunteers had no relief with 10 mg/w oral dose of MTX with/without other 1-2 inadequate dose of DMARDs for at least 3 months. They were randomly divided into 1:1 groups*. The experimental group would be treated with original DMARDs and incremental MTX (gradually increased to the optimal oral dose (0.3 mg/k/w) in the first 12 weeks and folic acid (the dose adjusted on demand with range from 5 mg/w to 5mg tid). While the control group would be treated with original MTX dose(10mg/w) but incremental original DMARDs(gradually increased to the maximum dose in the first 12 weeks). The two groups would keep the treatment at 12thweek last to the 36thweek, and the efficacy and safety indexes would be evaluated during the whole study.Results:1)We planned to recruit 160 RA patients in our study. 46 Hakka RA patients were enrolled in the study so far. 2 of 46 finished the 24thweek visit and 24 finished the 36thweek visit. The average age is 54.2± 9.3 years old, the average weight is 59.1±11.1kg, and the female to male ratio is 41:5.2)The average Folic acid dose is 14.4±9.5mg/w in the experimental group at the 12thweek.3)The morning stiffness time, PGA, PhGA, HAQ, DAS28 were better in experimental group after 12 weeks though slightly worse during 0-12 weeks. 100%(12) patients in experimental group, while 66.67%(8/12) in control group reach ACR20.4) Only 1 case(5.9%,1/23)had adverse event while 6 cases (26%,6/23) occurred adverse events. All events were mild level. 1 case (4.2%,1/23) in control group withdrew from the study because the disease was getting worse during 0-24 weeks.Conclusion:Hakka patients in China might have better outcomes due to increasing MTX to the 0.3mg/kg/w dose than increasing the other DMARDs. Therefore, We recommended the Chinses patients choose MTX as first incremental DMARD. The appropriate dose of Folic acid plus with the optimal dose of MTX in our study is higher than previous studies (such as 13.0±4.8mg/w reported by Gaujoux-Viala, 2018[1]). We recommended Chinese patients take 15mg/w folic acid to prevent MTX side effects in view of lower folic acid level in Chinese population.[3]References:[1]Gaujoux-Viala C, Rincheval N, Dougados M, et al.

Abstract
Isoflurane has been demonstrated to induce mitochondrial damage and cell apoptosis. The isoflurane-induced inflammation may be an important reason for this phenomenon. Studies have shown that ulinastatin (UTI) has an anti-inflammatory effect. Our aim was to investigate whether UTI could attenuate isoflurane-induced mitochondrial damage and cell apoptosis by inhibiting inflammation. Human neuroglioma H4 cells were exposed to isoflurane with or without UTI. The ratio of cell apoptosis was evaluated by flow cytometry. β-Amyloid (Aβ) peptide and cleaved caspase 3 expression were evaluated by Western blot analysis. The concentrations of tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β) were detected by sandwich enzyme-linked immunosorbent assays. Mitochondrial structural changes were detected by transmission electron microscopy. Mitochondrial membrane potential (Δψm) was determined by 5,5',6,6'-Tetrachloro-1,1',3,3'-tetraethyl-imidacarbocyanine iodide (JC-1). The activity of the mitochondrial electron transport chain (ETC) complexes I, II, III, and IV was determined by assay kits. UTI attenuated the TNF-α and IL-1β release induced by isoflurane. UTI could also reduce mitochondrial structure damage, mitigate the decrease in Δψm, and improve ETC complexes dysfunction. Furthermore, it decreased cell apoptosis induced by isoflurane in H4 cells. UTI had no effect on isoflurane-induced Aβ expression. UTI may mitigate isoflurane-induced mitochondrial damage and cytotoxicity by inhibiting inflammation.

Abstract
Several bioactive molecules isolated from the saliva of blood-sucking arthropods, such as mosquitoes, have been shown to exhibit potential anticoagulant function. We have previously identified a 30kDa allergen named Aegyptin-like protein (alALP), which is highly homologous to Aegyptin, from the salivary glands of female Aedes albopictus (Asian tiger mosquito). In this study, we identified the conserved functional domain of alALP by using bioinformatic tools, and expressed the His-tagged alALP recombinant protein in sf9 insect cells by generation and transfection of a baculoviral expression plasmid carrying the fulllength cDNA of alALP. We purified this recombinant protein and examined its function on the inhibition of blood coagulation. The results showed that the purified His-alALP prolonged the Activated Partial Thromboplastin Time (APTT), Prothrombin Time (PT) and Thrombin Time (TT) in vitro as well as the Bleeding Time (BT) in vivo, which suggest that alALP could be a novel anticoagulant.

Abstract
BACKGROUND Diabetes health care resource utilization (HCRU) studies tend to focus on patients with type 2 diabetes (T2D) or pool patients with T2D and type 1 diabetes (T1D). There is a paucity of recent data on the cost of treating patients with T1D in the United States. OBJECTIVES To (a) estimate the per-patient per-year (PPPY) HCRU and costs, from a payer perspective, associated with treating U.S. adults with T1D and (b) compare these with the HCRU and costs for patients with T2D. METHODS This retrospective cohort study used claims data from the Optum Clinformatics database between January 2015 and December 2017. Adults (aged ≥ 18 years) with a diagnosis of T1D were propensity score-matched to adults with T2D. Overall and nondiabetes-related HCRU and costs were assessed for T1D and T2D and compared between the 2 groups. RESULTS Propensity scores were used to match 10,103 patient pairs from T1D and T2D cohorts (mean ages 54.4 and 56.9 years, respectively). In the T1D cohort, inpatient, emergency department (ED), outpatient, and prescription claims occurred in 14.0%, 17.3%, 85.5%, and 100% of patients, respectively, resulting in a mean total cost of U.S. $18,817 PPPY (diabetes-related = $11,002; nondiabetes-related = $7,816). The T1D cohort had significantly higher mean total costs than the T2D cohort ($18,817 vs. $14,148 PPPY; P < 0.001). When extrapolating these findings to a commercial health plan with 1 million covered lives, the estimated total direct medical costs of T1D would be $103.4 million. CONCLUSIONS This study showed that the total annual cost of managing an adult with T1D is significantly higher than that of an adult with T2D. Nondiabetes costs accounted for 40% of the total per-patient cost, similar to patients with T2D, confirming that as patients with T1D live longer lives, they may also be at greater risk for cardiometabolic complications. DISCLOSURES This study was funded by Sanofi U.S. and Lexicon Pharmaceuticals as part of a business partnership in a diabetes program at the time this study was conducted. Joish and Davies are employees and stockholders of Lexicon Pharmaceuticals. Zhou, Preblick, and Paranjape are employees and stockholders of Sanofi.

Abstract
Purpose Serum immunoglobulins (Igs) play a critical role in modulating the immune response by neutralizing pathogens, although little is known about the effect of Igs in development of atherosclerotic cardiovascular disease (ASCVD). Elevated serum Immunoglobulin A (IgA) concentrations have been identified in previous studies in populations with obesity and hypertriglyceridemia, whereas variable concentrations of Immunoglobulin M (IgM) have been observed in the setting of dyslipidemia. Methods In this cross-sectional study, investigators examined the association of serum Ig concentrations with components of metabolic syndrome, including obesity, diabetes, and dyslipidemia. All consecutive adult patients aged 18 years or older discharged from two academic teaching hospitals with serum Immunoglobulin G (IgG) concentration measured during their admission were evaluated, with a total of 1809 individuals included and stratified into two groups: those with and those without dyslipidemia. Results Mean IgG concentration in individuals with and without dyslipidemia was 997 ± 485 mg/dL and 1144 ± 677 mg/dL, respectively (P < 0.0001). After controlling for confounders in the generalized linear model (GLM), the least square mean IgG concentration in individuals with and without dyslipidemia was 1095 and 1239 mg/dL, respectively (P < 0.0001). The mean IgA and IgM concentrations were not significantly different in individuals with and without dyslipidemia both before and after adjusting covariates. After controlling for confounding variables, all three serum Ig concentrations were not significantly different in individuals with and without diabetes. Conclusion Dyslipidemia was associated with a lower mean serum IgG concentration. No association with any serum Ig was indentified in individuals with diabetes. Exploration of the association between alterations in serum Igs and metabolic syndrome and the role of alterations of Ig concentrations in disease progression represents an important step in identification of appropriate targeted treatment options for reducing cardiovascular risk.
