RESUMO

Phytoremediation provides substantial advantages, including eco-friendliness, cost-effectiveness, efficiency, and visual appeal. However, the current knowledge of the factors influencing phytoremediation in pesticide-contaminated environments remains limited. It is critical to understand phytoremediation and the factors affecting the variation in removal efficiency. In this study, we compiled 72 previous research articles to quantify plant-induced improvements in removal efficiency and identify factors that influence variations in phytoremediation behavior through meta-analysis. We observed a significant increase in the removal efficiency of phytoremediation compared to the control group which did not involve phytoremediation. Pesticides significantly affect removal efficiency in terms of their modes of action, substance group, and properties. Plants demonstrated higher efficiency in remediating environments contaminated with pesticides possessing lower molecular masses and log Kow values. Plant species emerged as a crucial determinant of variations in removal efficiency. Annual plants exhibited a 1.45-fold higher removal efficiency than perennial plants. The removal efficiencies of different plant types decreased in the following order: agri-food crops > aquatic macrophytes > turfgrasses > medicinal plants > forage crops > woody trees. The Gramineae family, which was the most prevalent, demonstrated a robust and consistent phytoremediation ability. This study offers a more comprehensive triangular relationship between removal efficiency, pesticides, and plants, expanding the traditional linear model. Our findings offer valuable insights into the behavior of phytoremediation in pesticide-contaminated environments and the factors determining its success, ultimately guiding further research toward developing strategies for higher removal efficiency in phytoremediation.

RESUMO

@#Abstract: Objective To investigate the clinical and laboratory characteristics of pulmonary infection caused by Nocardia otitidiscaviarum. Methods The clinical data of a patient with pulmonary infection caused by Nocardia otitidiscaviarum were reported, and the clinical characteristics, laboratory characteristics and drug sensitivity of pulmonary infection caused by Nocardia otitidiscaviarum were summarized in combination with the relevant literature at home and abroad from January 2010 to December 2022. Results A 67-year-old female patient was admitted to the hospital on June 30, 2020 because of "repeated chest tightness and shortness of breath for 3 years, aggravated cough, expectoration and fever". The sputum, alveolar lavage fluid and blood of the patient were collected for culture, and the detected pathogenic bacteria were identified. There are pathogenic bacteria growing in sputum and alveolar lavage fluid, which are identified as Nocardia otitidiscaviarum by Autof ms mass spectrometer. According to the results of pathogenic bacteria and the patient's condition, meropenem combined with compound sulfamethoxazole tablets were given anti-infection treatment, and the patient's condition improved and discharged. Conclusion The clinical manifestations and imaging features of nocardiosis are lack of specificity, and are prone to misdiagnosis and missed diagnosis. Etiology is the key to disease diagnosis, and clinical examination and culture should be conducted in time.

RESUMO

Rapid and accurate evaluations of hematoma volume can guide the treatment of traumatic subdural hematoma. We aim to explore the consistency between the measurement results of traumatic subdural hematoma (TSDH) using a deep learn-based image segmentation algorithm. A retrospective study was conducted on 90 CT images of patients diagnosed with TSDH in our hospital from January 2019 to January 2022. All image data were measured by manual segmentation, convolutional neural networks (CNN) algorithm segmentation, and ABC/2 volume formula. With manual segmentation as the "golden standard," a consistency test was carried out with CNN algorithm segmentation and ABC/2 volume formula, respectively. The percentage error of CNN algorithm segmentation is less than ABC/2 volume formula. There is no significant difference between CNN algorithm segmentation and manual segmentation (P > 0.05). The area under curve of the ABC/2 volume formula, manual segmentation, and CNN algorithm segmentation is 0.811 (95% CI: 0.717~0.905), 0.840 (95% CI: 0.753~0.928), and 0.832 (95% CI: 0.742~0.922), respectively. From our results, the algorithm based on CNN has a good efficiency in segmentation and accurate calculation of TSDH hematoma volume.

RESUMO

OBJECTIVE: To explore the effectiveness of the micro-lecture education on the ability of self-management and lifestyle changes in patients with coronary artery disease. DESIGN: A randomized control trial with a 12-week follow-up. SETTING: Cardiology wards of a large Chinese University Hospital. SUBJECTS: One hundred eligible inpatients with coronary artery disease were recruited. INTERVENTION: Intervention group received the micro-lecture education, while the control group received the traditional cardiac rehabilitation education. MAIN MEASURES: Primary outcome of the ability of coronary self-management was assessed by the Coronary self-management scaleat baseline, 12-week after discharge. Secondary outcomes of smoking status, exercise status, and six-minute walk distance were evaluated at the baseline, week4 and week 12 after discharge. The chi-square test,Fisher's exact test, group t-test and the repeated measure variance were used for the data analysis. RESULTS: Eighty-nine of 100 eligible participants responded, and mean age was 60.2 ± 11.3 years.After the intervention, the mean score of the coronary self-management scale (3.84 ± 0.36) was higher than that in the control group (2.78 ± 0.57).At week 12, the rate of re-smoked in the intervention group (6%) was significantly lower than that in the control group (43%),the frequency of the exercise (85%), and the 6MWD (495.55 ± 85.94) in the intervention group were better than the control group. CONCLUSION: Micro-lecture education program presented a positive effect on promoting the ability of self-management, and apotential effect on the therapeutic lifestyle changes for the coronary artery disease patients.

RESUMO

BACKGROUND: Emotional intelligence training relieves stress and promotes resilience among nurses. Previous studies have not sufficiently explored the effect of emotional intelligence training among nurses on the experience of inpatients under their care. OBJECTIVE: To explore the effects of emotional intelligence training on emotional intelligence, resilience, and perceived stress among nurses and examine how training affects inpatient experience. DESIGN: Randomized controlled trial. SETTING: A tertiary general hospital in Changsha, China. PARTICIPANTS: A total of 103 nurses were randomly selected from 20 wards. METHODS: The wards were randomized into two groups. The intervention group (n = 53 nurses) received emotional intelligence training in two phases: Phase I-system training phase, twice a week for one month; Phase II-a consolidated learning phase, once a week for 11 months. The control group (n = 50) received daily briefings in meetings between head nurses, which were held regularly to discuss specific problems. There was no emotional intelligence training conducted with the control group. Data were collected at baseline and after the intervention. RESULTS: Emotional intelligence training improved emotional intelligence, resilience, and stress in the intervention group. The control group scored lower on the Wong and Law's Emotional Intelligence Scale and all subscales, showed stability in the scores on the Connor-Davidson Resilience Scale and its subscales, and very little change in stress scores. Repeated measures analysis of variance showed significantly greater beneficial changes in the intervention group on all but the optimism subscale. There were suggestive differences in the predicted direction between the emotional intelligence training wards and the control wards at post-test on the patient experience scale and the four subscales. CONCLUSION: Our study suggests that emotional intelligence training improves emotional intelligence, resilience, and stress among nurses and leads to improvements in inpatient experience. Emotional intelligence training should be part of nurse education to improve the quality of care nurses provide and their ability to work without increased stress.

RESUMO

Fungi play an irreplaceable role in drug discovery in the course of human history, as they possess unique abilities to synthesize diverse specialized metabolites with significant medicinal potential. Trichoderma are well-studied filamentous fungi generally observed in nature, which are widely marketed as biocontrol agents. The secondary metabolites produced by Trichoderma have gained extensive attention since they possess attractive chemical structures with remarkable biological activities. A large number of metabolites have been isolated from Trichoderma species in recent years. A previous review by Reino et al. summarized 186 compounds isolated from Trichoderma as well as their biological activities up to 2008. To update the relevant list of reviews of secondary metabolites produced from Trichoderma sp., we provide a comprehensive overview in regard to the newly described metabolites of Trichoderma from the beginning of 2009 to the end of 2020, with emphasis on their chemistry and various bioactivities. A total of 203 compounds with considerable bioactivities are included in this review, which is worth expecting for the discovery of new drug leads and agrochemicals in the foreseeable future. Moreover, new strategies for discovering secondary metabolites of Trichoderma in recent years are also discussed herein.

RESUMO

Marine-derived fungi are a treasure house for the discovery of structurally novel secondary metabolites with potential pharmaceutical value. In this study, a pair of new nor-bisabolane derivative enantiomers (±)-1 and two new phthalides (4 and 5), as well as four known metabolites, were isolated from the culture filtrate of the marine algal-derived endophytic fungus Penicillium chrysogenum LD-201810. Their structures were established by detailed interpretation of spectroscopic data (1D/2D NMR and ESI-MS). The optical resolution of compound (±)-1 by chiral HPLC successfully afforded individual enantiomers (+)-1 and (-)-1, and their absolute configurations were determined by TDDFT-ECD calculations. Compound (±)-1 represents the first example of bisabolane analogs with a methylsulfinyl substituent group, which is rare in natural products. All of the isolated compounds 1-7 were evaluated for their cytotoxic activity against A549, BT-549, HeLa, HepG2, MCF-7, and THP-1 cell lines, as well as for antifungal activity against four plant pathogenetic fungi (Alternaria solani, Botrytis cinerea, Fusarium oxysporum, and Valsa mali). Compound 2, a bisabolane-type sesquiterpenoid, was shown to possess excellent activity for control of B. cinerea with half-maximal inhibitory concentration (IC50) of 13.6 µg/mL, whereas the remaining investigated compounds showed either weak or no cytotoxic/antifungal activity in this study.

RESUMO

Yin and Yang are the two counter-balancing aspects in ancient Chinese philosophy. In traditional Chinese medicine, Yin deficiency syndrome (YDS) is a common sub-health state with complex causes. While the syndrome may be treated to various degrees of effectiveness with traditional Chinese medicine, efficient modern methods are yet to be developed for diagnosing and treating the YDS. Here we performed a metabolomics study on YDS in rats. Serum metabolites in rats were analyzed using ultra-performance liquid chromatography-mass spectrometry (UPLC-MS) method to identify potential biomarkers for YDS. The rats were divided randomly into the healthy control group, the untreated YDS group, and the anemarrhena treated YDS group. Compared with the control group, significant increase in the metabolites such as dihydrotestosterone (DHT) and 5ß-DHT, 4-imidazolone-5-propanoate, 4-(L-alanin-3-yl)-2-hydroxy-cis,cis-muconate 6-semialdehyde, and 5-(L-alanin-3-yl)-2-hydroxy-cis,cis-muconate 6-semialdehyde were observed in the serum of untreated YDS group, which returned to normal in the anemarrhena treated group. Therefore, these metabolites may serve as potential biomarkers for YDS, and may facilitate the diagnosis and treatment of YDS.

RESUMO

BACKGROUND: Delayed cerebral ischemia (DCI) is a severe complication after aneurysmal subarachnoid hemorrhage (aSAH). Tissue kallikrein (TK), a subgroup of serine proteinases, is an important component of the kallikrein-kinin system. Exogenous TK attenuated cerebral vasospasm in a rabbit model of subarachnoid hemorrhage. We intended to discern association of serum TK levels with aSAH-related DCI. METHODS: Serum TK levels were detected in a total of 92 aSAH patients and 92 healthy controls. A multivariate logistic regression model was configured to investigate relationship between TK levels and occurrence of DCI. RESULTS: TK levels were substantially lower in aSAH patients than in controls. TK levels were strongly correlated with World Federation of Neurological Surgeons (WFNS) score and modified Fisher score. Serum TK, WFNS score and modified Fisher score retained as the three independent predictors for DCI. Under receiver operating characteristic curve, predictive capability of TK levels was in the range of WFNS score and modified Fisher score, as well as TK levels could remarkably improve predictive abilities of WFNS score and modified Fisher score. CONCLUSIONS: Serum TK emerges as a potential biomarker for assessment of hemorrhagic severity and prediction of DCI following aSAH.

RESUMO

BACKGROUND: Lipoprotein-associated phospholipase A2 (Lp-PLA2) is reflective of vascular inflammation and plays a role in the pathophysiology of cerebrovascular disease. We determine usefulness of serum Lp-PLA2 as a prognostic biomarker for intracerebral hemorrhage (ICH). METHODS: In this prospective, observational study, serum Lp-PLA2 concentrations were detected among 164 patients with acute spontaneous basal ganglia hemorrhage and 164 healthy controls. Using multivariate analysis, we analyzed its association with poor outcome (modified Rankin Scale >2) at poststroke 90 days and hemorrhagic severity indicated by National Institutes of Health Stroke Scale (NIHSS) score and hematoma volume. RESULTS: Serum Lp-PLA2 concentrations were remarkably higher in patients than in controls. Lp-PLA2 concentrations were independently correlated with NIHSS score (t = 5.095, P < .001) and hematoma volume (t = 2.850, P = .005). At 90-day follow-up, 85 patients (51.8%) had poor outcome. Under receiver operating characteristic curve, serum Lp-PLA2 showed a significant prognostic discriminatory capability (AUC, 0.813; 95% CI, 0.744-0.869). Serum Lp-PLA2 concentrations ≥304 ng/ml was an independent predictor associated with poor outcome (OR 7.052; 95% CI 1.971-25.228). CONCLUSIONS: Rising serum Lp-PLA2 concentrations are closely hemorrhagic severity and clinical outcomes after ICH, substantializing serum Lp-PLA2 as a potential prognostic biomarker of ICH.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Zhibai Dihuang Granule (ZDG), a traditional Chinese medicine (TCM) made from eight Chinese herbs, has been classically used to treat Yin-deficiency-heat (YDH) syndrome. ZDG is well known with the therapeutic efficacy of nourishing Yin and decreasing internal heat in clinic, but the mechanism of ZDG's therapeutic effect is still not clear. MATERIALS AND METHODS: High doses of triiodothyronine (T3) were given intraperitoneally to induce Hyperthyroid YDH syndrome in SD rats. The animals were then treated with ZDG for one week. The iTRAQ-coupled with two-dimensional liquid chromatography-tandem mass spectrometry (2D LC-MS/MS) technique was used to screen the differentially expressed serum proteins between ZDG treated rats and YDH syndrome rats. The differentially expressed proteins were analyzed by bioinformatics method and were verified by enzyme-linked immunosorbent assay (ELISA). RESULTS: A total of 55 differentially expressed proteins were identified, including 23 up-regulated proteins (>1.25 fold, p < 0.05) and 32 down-regulated proteins (<0.80 fold, p < 0.05). Among the differentially expressed proteins, 26 proteins returned to normal after ZDG treatment. Bioinformatics analysis showed that these proteins were mainly involved in immune response, including regulation of immune system process, complement activation, and humoral immune response mediated by circulating immunoglobulin. ELISA revealed significantly increased levels of Zinc-alpha-2-glycoprotein (Azgp1), L-selectin, C-reactive protein (Crp), Plasminogen (Plg), Kininogen 1 (Kng1), and significantly decreased levels of Mannose binding lectin 2 (Mbl2) and Complement C1qb chain (C1qb) in ZDG treated rats compared with YDH syndrome rats. Bioinformatics analyses indicated that Azgp1 participated in antigen processing and presentation, Crp, C1qb, and Mbl2 were involved in complement activation, while L-selectin, Plg, and Kng1 were involved in regulating the inflammatory response. CONCLUSIONS: Our study provides experimental evidence to understand the therapeutic mechanism of ZDG in YDH syndrome. The results suggested that ZDG may regulate the complement activation and inflammatory response, and promote the ability to recognize antigens to alleviate YDH syndrome.

RESUMO

Rapid and efficient methods for the determination of cured pulmonary tuberculosis (TB) are lacking. We screened serum miRNAs using the Solexa sequencing method among untreated TB patients, two-month treated TB patients, cured TB patients, and healthy controls. A total of 100 differentially expressed miRNAs were identified in cured TB patients, including 37 up-regulated (fold change >1.50, P < 0.05) and 63 down-regulated (fold change <0.60, P < 0.05) miRNAs. Gene ontology (GO) enrichment analysis revealed that most of the predicted genes were present in the nucleus with a strong protein binding function. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis strongly suggested alterations in the metabolic pathways. Following quantitative real time chain reaction (qRT-PCR), significantly reduced expression levels of miR-21-5p (0.30, P < 0.001), miR-92a-3p (0.63, P < 0.001), and miR-148b-3p (0.17, P < 0.001) were found in the cured TB patients compared with the untreated TB patients, while significantly increased expression levels of miR-21-5p (2.09, P = 0.001), miR-92a-3p (1.40, P = 0.005), and miR-148b-3p (4.80, P = 0.003) were found in the untreated TB patients compared with the healthy controls. And significantly increased level of miR-125a-5p was found between two-month treated TB patients and untreated TB patients (1.81, P = 0.004). We established a cured TB model with 83.96% accuracy by four miRNAs (miR-21-5p, miR-92a-3p, miR-148b-3p, and miR-125a-5p), and also established a diagnostic model with 70.09% accuracy. Our study provides experimental data for establishing objective indicators of cured TB, and also provides a new experimental basis to understand the pathogenesis and prognosis of TB.

RESUMO

BACKGROUND: Outpatient facilities, such as community behavioral health organizations (CBHOs), play a critical role in the care of patients with serious mental illness, but there is a paucity of "real-world" patient outcomes data from this health care setting. Therefore, we conducted The Research and Evaluation of Antipsychotic Treatment in Community Behavioral Health Organizations, Outcomes (REACH-OUT) trial, a real-world, prospective, noninterventional observational study of patients with mental illness treated at CBHOs across the United States. We describe demographic and clinical characteristics, antipsychotic therapy (APT) treatment patterns, and health care resource utilization in patients with schizophrenia undergoing medical care as usual. METHODS: This study enrolled adults with schizophrenia or bipolar I disorder who initiated APT treatment at various time points: 1) within 8 weeks of initiating risperidone long-acting injectables (RLAIs) or other APTs except paliperidone palmitate (PP), 2) after more than 24 weeks of continuous RLAI treatment, or 3) at any time after initiating PP LAI treatment (schizophrenia only). Study assessments were performed via participant interview, medical chart abstraction, and clinical survey at enrollment and at month 12. RESULTS: A total of 1065 patients from 46 CBHOs were enrolled. Of these, 944 (88.6%) had a diagnosis of schizophrenia and 121 (11.4%) had bipolar I disorder. At enrollment, 599 (63.5%) of patients with schizophrenia were receiving RLAIs or PP LAI, 281 (29.8%) were receiving oral APTs, and 64 (6.8%) were receiving other injectable APTs. A number of differences in patient characteristics and outcomes were observed between patients in the LAI APT cohort and the oral APT cohort. CONCLUSION: Descriptive analyses from this observational study suggest differences in the patient characteristics, treatment patterns, and clinical and economic outcomes among those with schizophrenia treated at CBHOs with LAI APT or oral APTs. Additional analyses will be conducted to delineate the impact of LAI APT versus oral APTs on patient outcomes. TRIAL REGISTRATION: Clinical Trial Registry: NCT01181960 . Registered 12 August 2010.

RESUMO

BACKGROUND: Zhibai Dihuang Granule (ZDG) is a traditional Chinese medicine which has been used to treat Yin-deficiency-heat (YDH) syndrome for thousands of years in China. However, little work has been conducted to explore the molecular mechanism of ZDG in YDH syndrome, and the processes of YDH syndrome prevention and treatment have been developed slowly. The present study was aimed to explore the therapeutic mechanism of ZDG on YDH syndrome. METHODS: The YDH syndrome rats were induced by hot Chinese herbs, then treated by ZDG orally for 1 week. Body weight was measured every 2 days. After sacrifice, blood samples were collected and the thymus, adrenal glands, spleen, and liver were immediately removed and weighed. iTRAQ-based proteomics approach was applied to explore the serum protein alterations with the treatment of ZDG, and to investigate the underlying mechanism of ZDG in treating YDH syndrome. RESULTS: The body weights of YDH syndrome rats were significantly decreased compared with control group, and increased in ZDG treated rats. The relative weights of thymus in YDH syndrome rats were increased compared with the control rats, and significantly decreased in after ZDG treatment. In the proteomic analyses, seventy-one proteins were differentially expressed in the YDH syndrome group and the ZDG treated group, including 10 up-regulated and 61 down-regulated proteins. Gene ontology analysis revealed that the differentially expressed proteins were mostly related to immune response, and pathway enrichment analysis showed that these proteins were enriched in coagulation and complement cascades. Enzyme-linked immunosorbent assay was performed to detect the protein levels in coagulation and complement cascades, and the results showed that complement component 5 levels were significantly increased, while fibrinogen gamma chain levels were significantly decreased in the ZDG treated group. CONCLUSIONS: We found that ZDG treatment could lead to proteins alteration in immune response, especially in coagulation and complement cascades. ZDG can up-regulate the proteins in the complement cascade to eliminate pathogens, and down-regulate the proteins in the coagulation cascade to suppress inflammation. Our study provides experimental basis to understand the therapeutic mechanism of ZDG and revealed that ZDG can regulate coagulation and complement cascades in treating YDH syndrome.

RESUMO

AIM: Long-acting injectable antipsychotics (APs) are not well studied in recent-onset schizophrenia. This exploratory analysis of a study designed to reflect real-world schizophrenia, as defined by patients, interventions and outcomes, compared relative treatment effect between once-monthly paliperidone palmitate (PP) and daily oral APs in patients with recent-onset or chronic illness METHODS: This randomized, open-label, event monitoring board-blinded study compared treatment response in subjects with schizophrenia and a history of criminal justice system involvement following treatment with PP or oral APs for 15 months (ClinicalTrials.gov identifier, NCT01157351). Event-free probabilities were estimated using Kaplan-Meier method; hazard ratios (HRs) were estimated using Cox proportional hazard models. This subgroup analysis analysed data by disease duration (≤5 (recent-onset) or >5 years (chronic illness) since first psychiatric diagnosis). RESULTS: Seventy-seven subjects met the criteria for recent-onset illness; 365 for chronic illness. HRs (95% CI) for treatment failure for oral APs versus PP were 1.73 (0.87-3.45; P = 0.121) for recent-onset and 1.37 (1.02-1.85; P = 0.039) for chronic illness. Most common adverse events for PP versus oral APs were injection site pain (recent-onset, 26% vs. 0%; chronic, 17% vs. 0%), increased weight (14% vs. 6%; 12% vs. 6%), akathisia (14% vs. 9%; 10% vs. 7%), insomnia (12% vs. 17%; 18% vs. 10%) and anxiety (12% vs. 6%; 10% vs. 8%). CONCLUSIONS: Although neither pre-planned nor adequately powered, the estimated HRs suggest that the relative advantage of PP over oral APs for reducing the risk for treatment failure may be greater in patients with recent-onset schizophrenia than in those with more chronic illness.

RESUMO

AIM: This study aimed to compare the outcomes of pelvic floor muscle training (PFMT) between postpartum and non-postpartum women with stress urinary incontinence (SUI) and to detect potential factors that may influence these outcomes. METHODS: A total of 54 and 79 participants were recruited into postpartum (PP group) and non-postpartum (non-PP group) groups, respectively. A physiotherapist treated the participants twice a week for 6-8 weeks. At baseline and 6 and 12 months after treatment, the 1-h pad weight test (PWT), vaginal contraction pressure (VCP), and Incontinence Impact Questionnaire Short Form (IIQ-7) were assessed by an evaluator or physiotherapist. The primary outcome was PWT improvement. The participants whose PWT improvement reached a >50% reduction relative to baseline were considered responders. Secondary outcomes included VCP, IIQ-7 score, and patient satisfaction rate. RESULTS: The PWT improvement was 87.04% (95%CI: 0.78, 0.96) in the PP group at 1-year follow-up, which was significantly better than the 72.15% improvement (95%CI: 0.62, 0.82) in the non-PP group (OR = 2.591, 95%CI: 1.018, 6.595, P = 0.041). Changes in VCP and BMI were significant predictors of responders in the regression analysis. As the change in VCP increased by 1 cmH2 O, the efficiency increased by 4.2% (OR = 1.042, 95%CI: 1.010, 1.070). The change in BMI increased by 1 kg/m2 , and the efficiency decreased 23.0% (OR = 0.770, 95%CI: 0.633, 0.937). CONCLUSIONS: The outcome of PFMT in postpartum participants with SUI was better than that in non-postpartum participants. Women with more improvements in VCP and weight loss showed better amelioration of SUI symptoms after PFMT.

RESUMO

INTRODUCTION: Comorbid substance abuse is known to blunt response to treatment for underlying psychiatric disorders, but it has not been investigated in schizophrenia when comparing the effects of long-acting injectable antipsychotics with those of oral antipsychotics. METHODS: This exploratory analysis compared once-monthly paliperidone palmitate (PP1M) with daily oral antipsychotics on time to treatment failure in patients with schizophrenia and a history of incarceration. Subjects were stratified into substance abuse (reported substance or alcohol misuse in the past 30days on the baseline Addiction Severity Index-Lite Version and/or met criteria for a current MINI diagnosis of a substance abuse disorder) and nonabuse cohorts. RESULTS: In the substance abuse cohort, treatment failure was observed in 56.2% (73/130) and 64.2% (86/134) of subjects in the PP1M and oral antipsychotic groups, respectively. For the nonabuse cohort, treatment failure was observed in 36.5% (35/96) and 53.6% (45/84) of subjects in the PP1M and oral antipsychotic groups, respectively. Median (95% confidence interval [CI]) time to first treatment failure was 291 (179-428) days and 186 (94-296) days in the PP1M and oral antipsychotic groups, respectively. Median (95% CI) time to first treatment failure was >450 and 284 (147 to >450) days in the respective treatment groups. CONCLUSION: Greater treatment effects were evident with PP1M compared with oral antipsychotics in both cohorts. The observed beneficial effect of PP1M was attenuated in the substance-abuse cohort, further reinforcing both the need for and value of continued research to optimize patient care in these complex patient populations.

RESUMO

Pulmonary tuberculosis (TB) is among the diseases with the highest morbidity and mortality worldwide. Effective diagnostic methods for TB are lacking. In this study, we investigated long non-coding RNAs (lncRNAs) in plasma using microarray and the potential diagnostic value of lncRNAs for TB. We found a total of 163 up-regulated lncRNAs and 348 down-regulated lncRNAs. Gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and coding-noncoding co-expression (CNC) analyses showed that functions of differentially expressed lncRNAs were mainly enriched in the regulation of alpha-beta T cell activation and the T cell receptor signalling pathway. Four differentially expressed lncRNAs, NR_038221 (fold change = 3.79, P < 0.01), NR_003142 (fold change = 1.69, P < 0.05), ENST00000570366 (fold change = 3.04, P < 0.05), and ENST00000422183 (fold change = 2.11, P < 0.001), were verified using RT-qPCR. Among those, NR_038221, NR_003142, and ENST00000570366 were found to be up-regulated, while ENST00000422183 was down-regulated. The value of the area under the curve (AUC) for the diagnostic model consisting of the four lncRNAs was 0.845 (sensitivity = 79.2%, specificity = 75%). We further predicted 85 mRNAs and 404 miRNAs that potentially interact with these lncRNAs. Our study revealed the potential value of lncRNAs as biomarkers for early diagnosis of TB and the underlying mechanisms of these abnormally expressed lncRNAs in the pathogenesis of TB.

RESUMO

OBJECTIVE: This analysis of the Paliperidone Palmitate Research in Demonstrating Effectiveness (PRIDE) study (NCT01157351) compared outcomes after administration of once-monthly paliperidone palmitate (PP) vs conventional oral antipsychotics (COAs) or atypical oral antipsychotics (AOAs). METHODS: PRIDE was a 15-month study of 444 individuals with schizophrenia and a history of incarceration. They were randomly assigned to PP or to 1 of 7 commonly prescribed OAs. Primary endpoint was time to first treatment failure (TF). Event-free probabilities were estimated using the Kaplan-Meier method; treatment group differences (PP vs COAs, PP vs AOAs, and PP vs oral paliperidone/risperidone) were assessed using a log-rank test. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards regression models. No adjustment was made for multiplicity. RESULTS: Compared with PP, risk for first TF was 34% higher with COAs (HR: 1.34; 95% CI: 0.80-2.25), 41% higher with AOAs (HR: 1.41; 95% CI: 1.06-1.88), and 39% higher with paliperidone/risperidone (HR: 1.39; 95% CI: 0.97-1.99). Incidences of extrapyramidal symptom-related adverse events (AEs) were 45.7%, 13.7%, and 10.6% in the COA, AOA, and oral paliperidone/risperidone groups vs 23.9% in the PP group. Incidences of prolactin-related AEs were 5.7%, 3.8%, and 3.5% vs 23.5%, and incidences of ≥7% weight increase were 11.4%, 14.9%, and 16.0% vs 32.4%. CONCLUSIONS: Results suggest a lower risk of TF but a higher rate of some AEs after treatment with PP vs COAs, AOAs, and paliperidone/risperidone. Deselection of specific OAs and low patient-compliance rates with OAs likely biased the safety results.

RESUMO

OBJECTIVE: The increasing importance of real-world data for clinical and policy decision making is driving a need for close attention to the pragmatic versus explanatory features of trial designs. ASPECT-R (A Study Pragmatic-Explanatory Characterization Tool-Rating) is an instrument informed by the PRECIS tool, which was developed to assist researchers in designing trials that are more pragmatic or explanatory. ASPECT-R refined the PRECIS domains and includes a detailed anchored rating system. This analysis established the inter-rater reliability of ASPECT-R. DESIGN: Nine raters (identified from a convenience sample of persons knowledgeable about psychiatry clinical research/study design) received ASPECT-R training materials and 12 study publications. Selected studies assessed antipsychotic treatment in schizophrenia, were published in peer-reviewed journals, and represented a range of studies across a pragmatic-explanatory continuum as determined by authors (CB/LA). After completing training, raters reviewed the 12 studies and rated the study domains using ASPECT-R. Intraclass correlation coefficients were estimated for total and domain scores. Qualitative ratings then were assigned to describe the inter-rater reliability. RESULTS: ASPECT-R scores for the 12 studies were completed by seven raters. The ASPECT-R total score intraclass correlation coefficient was 0.87, corresponding to an excellent inter-rater reliability. Domain intraclass correlation coefficients ranged from 0.85 to 0.31, corresponding to excellent to poor inter-rater reliability. CONCLUSION: The inter-rater reliability of the ASPECT-R total score was excellent, with excellent to good inter-rater reliability for most domains. The fair to poor inter-rater reliability for two domains may reflect a need for improved domain definition, anchoring, or training materials. ASPECT-R can be used to help understand the pragmaticexplanatory nature of completed or planned trials.
