Caught in the "NEET Trap": The Intersection Between Vocational Inactivity and Disengagement From an Early Intervention Service for Psychosis.

OBJECTIVE: Given the benefits of early intervention for psychosis and the social disengagement of youths not in education, employment, or training (NEET), this study sought to examine how being vocationally inactive (NEET) affects engagement in early intervention services. Both baseline vocational status and vocational trajectory in the first year of treatment were analyzed. METHODS: Data from 394 patients of a Canadian early intervention service were analyzed using time-to-event and Cox proportional hazards regression analyses. Two-year disengagement rates were compared between patients who were vocationally inactive and active at baseline and between those who remained vocationally inactive until month 12 and those who were vocationally inactive only at baseline. Pertinent sociodemographic (age, sex, visible minority status, social and material deprivation indices, and family involvement), and clinical (duration of untreated psychosis, substance use disorder, medication nonadherence, and baseline positive and negative symptoms) factors were considered. RESULTS: There was no statistically significant difference between the disengagement rates of those who were vocationally inactive (N=154) and those who were vocationally active (N=240) at baseline. Those who remained vocationally inactive at month 12 (N=77) were likelier to disengage in the second year than those who were vocationally inactive only at baseline (N=48) (χ2=5.44, df=1, p<0.05). This comparison remained significant in the regression analysis (hazard ratio [HR]=8.52, 95% confidence interval [95% CI]=1.54-47.1). The association of disengagement from services with lack of family contact with the treatment team (HR=3.91, 95% CI=0.98-15.6) and with greater material deprivation (HR=1.03, 95% CI=1.00-1.07) trended toward significance. CONCLUSIONS: The functional recovery of youths who are vocationally inactive when they enter services can affect their long-term service engagement and merits targeting by evidence-based interventions.
Sulfur Doping: Unique Strategy To Improve the Supercapacitive Performance of Carbon Nano-onions.

Recently, enhancement of the energy density of a supercapacitor is restricted by the inferior capacitance of negative electrodes, which impedes the commercial development of high-performance symmetric and asymmetric supercapacitors. This article introduces the in situ bulk-quantity synthesis of hydrophilic, porous, graphitic sulfur-doped carbon nano-onions (S-CNO) using a facile flame-pyrolysis technique and evaluated its potential applications as a high-performance supercapacitor electrode in a symmetric device configuration. The high-surface wettability in the as-prepared state enables the formation of highly suspended active conducting material S-CNO ink, which eliminates the routine use of binders for the electrode preparation. The as-prepared S-CNO displayed encouraging features for electrochemical energy storage applications with a high specific surface area (950 m2 g-1), ordered mesoporous structure (∼3.9 nm), high S-content (∼3.6 at. %), and substantial electronic conductivity, as indicated by the ∼80% sp2 graphitic carbon content. The in situ sulfur incorporation into the carbon framework of the CNO resulted in a high-polarized surface with well-distributed reversible pseudosites, increasing the electrode-electrolyte interaction and improving the overall conductivity. The S-CNOs showed a specific capacitance of 305 F g-1, an energy density of 10.6 W h kg-1, and a power density of 1004 W kg-1 at an applied current density of 2 A g-1 in a symmetrical two-electrode cell configuration, which is approximately three times higher than that of the pristine CNO-based device in a similar electrochemical testing environment. Even at 11 A g-1, the S-CNO||S-CNO device rendered an energy density (6.1 W h kg-1) at a deliverable power density of 5.5 kW kg-1, indicating a very good rate capability and power management during peak power delivery applications. Furthermore, it showed a high degree of electrochemical reversibility with excellent cycling stability, retaining ∼95% of its initial capacitance after more than 10 000 repetitive charge-discharge cycles at an applied current density of 5 A g-1.
Enhancing hydrogen production through anaerobic co-digestion of fruit waste with biosolids

Abstract In the present study, anaerobic co-digestion process was carried out with 23 mixed substrates proportion (MSP) of fruit waste (FRW), municipal wastewater treatment plant aerated biosolid (MPABS) and dairy effluent treatment plant returned biosolid (DPRBS). During co-digestion process, the effect of MSP on carbon/nitrogen (C/N) ratio and hydrogen production was investigated. The results revealed that MSP17 (70 FRW:20 MPABS:10 DPRBS) has yielded maximal hydrogen production of 295 mL with C/N ratio of 30, followed by MSP9 (70 FRW:30 DPRBS) exhibiting 253 mL of hydrogen production with C/N ratio of 29 and MSP2 (90 FRW:10 MPABS) attained 223 mL of hydrogen production with C/N ratio of 27. Then, SEM analysis of digested substrate sample was also performed in which flocs observed to be small and loose in structure in co-digested samples and intact form in non co-digested samples. Hence, this study results can be used for a sustainable approach by utilizing the FRW and biosolids for hydrogen production.
Suppressor of Variegation 3–9 Homolog 2, a Novel Binding Protein of Translationally Controlled Tumor Protein, Regulates Cancer Cell Proliferation

Suppressor of Variegation 3–9 Homolog 2 (SUV39H2) methylates the lysine 9 residue of histone H3 and induces heterochromatin formation, resulting in transcriptional repression or silencing of target genes. SUV39H1 and SUV39H2 have a role in embryonic development, and SUV39H1 was shown to suppress cell cycle progression associated with Rb. However, the function of human SUV39H2 has not been extensively studied. We observed that forced expression of SUV39H2 decreased cell proliferation by inducing G1 cell cycle arrest. In addition, SUV39H2 was degraded through the ubiquitin-proteasomal pathway. Using yeast two-hybrid screening to address the degradation mechanism and function of SUV39H2, we identified translationally controlled tumor protein (TCTP) as an SUV39H2-interacting molecule. Mapping of the interacting regions indicated that the N-terminal 60 amino acids (aa) of full-length SUV39H2 and the C-terminus of TCTP (120–172 aa) were critical for binding. The interaction of SUV39H2 and TCTP was further confirmed by co-immunoprecipitation and immunofluorescence staining for colocalization. Moreover, depletion of TCTP by RNAi led to up-regulation of SUV39H2 protein, while TCTP overexpression reduced SUV39H2 protein level. The half-life of SUV39H2 protein was significantly extended upon TCTP depletion. These results clearly indicate that TCTP negatively regulates the expression of SUV39H2 post-translationally. Furthermore, SUV39H2 induced apoptotic cell death in TCTP-knockdown cells. Taken together, we identified SUV39H2, as a novel target protein of TCTP and demonstrated that SUV39H2 regulates cell proliferation of lung cancer cells.
Comparison of Gemcitabine monotherapy with Gemcitabine and Cisplatin combination in metastatic pancreatic cancer: a retrospective analysis.

PURPOSE Gemcitabine is among the standard first-line agents for the treatment of metastatic pancreatic cancer. However, as the median survival with gemcitabine monotherapy is 6 months, different combinations are being studied for better, prolonged survival. In this multicenter study, we aimed to compare the results of gemcitabine monotherapy with those of gemcitabine and cisplatin combination therapy as first-line treatments for metastatic pancreatic cancer. METHODS Data of 664 patients diagnosed with metastatic pancreatic cancer between January 2007 and December 2016 from seven oncology centers in Turkey were retrospectively evaluated, and 319 patients with gemcitabine alone (n=138) or gemcitabine and cisplatin combination (n=181) as first-line treatment were included. RESULTS The median patient age was 62 years (range 42-79), being 60 years (42-75) in the gemcitabine/cisplatin arm and 67 years (52-79) in gemcitabine alone arm. no complete response was observed in either arm, whereas partial response rates were 30.1% in gemcitabine/cisplatin arm and 15.3% in gemcitabine alone arm (p=0.001). median overall survival was 8 months (95% CI:7.7-10.2) and was significantly longer in the gemcitabine/cisplatin arm than in the gemcitabine alone arm (10 vs. 6 months, p=0.004). CONCLUSION The cemcitabine and cisplatin combination therapy as first-line treatment of metastatic pancreatic cancer yields significantly prolonged survival over gemcitabine monotherapy. In patients with favorable performance conditions, the combination therapy should be preferred.
Maize Dek15 Encodes the Cohesin-Loading Complex Subunit SCC4 and Is Essential for Chromosome Segregation and Kernel Development[OPEN]

The classic maize mutant dek15 is mutated in a cohesin loader subunit SISTER CHROMATID COHESION PROTEIN 4 that is essential for mitotic chromosome segregation and maize kernel development. Cohesin complexes maintain sister chromatid cohesion to ensure proper chromosome segregation during mitosis and meiosis. In plants, the exact components and functions of the cohesin complex remain poorly understood. Here, we positionally cloned the classic maize (Zea mays) mutant defective kernel 15 (dek15), revealing that it encodes a homolog of SISTER CHROMATID COHESION PROTEIN 4 (SCC4), a loader subunit of the cohesin ring. Developing dek15 kernels contained fewer cells than the wild type, but had a highly variable cell size. The dek15 mutation was found to disrupt the mitotic cell cycle and endoreduplication, resulting in a reduced endosperm and embryo lethality. The cells in the dek15 endosperm and embryo exhibited precocious sister chromatid separation and other chromosome segregation errors, including misaligned chromosomes, lagging chromosomes, and micronuclei, resulting in a high percentage of aneuploid cells. The loss of Dek15/Scc4 function upregulated the expression of genes involved in cell cycle progression and stress responses, and downregulated key genes involved in organic synthesis during maize endosperm development. Our yeast two-hybrid screen identified the chromatin remodeling proteins chromatin remodeling factor 4, chromatin remodeling complex subunit B (CHB)102, CHB105, and CHB106 as SCC4-interacting proteins, suggesting a possible mechanism by which the cohesin ring is loaded onto chromatin in plant cells. This study revealed biological functions for DEK15/SCC4 in mitotic chromosome segregation and kernel development in maize.
Optimizing robot path in dynamic environments using Genetic Algorithm and Bezier Curve

Robots have recently gained a great attention due to their potential to work in dynamic and complex environments with obstacles, which make searching for an optimum path on-the-fly an open challenge. To address this problem, this paper proposes a Genetic Algorithm (GA) based path planning method to work in a dynamic environment called GADPP. The proposed method uses Bezier Curve to refine the final path according to the control points identified by our GADPP. To update the path during its movement, the robot receives a signal from a Base Station (BS) based on the alerts that are periodically triggered by sensors. Compared to the state-of-the-art methods, GADPP improves the performance of robot based applications in terms of the path length, the smoothness of the path, and the required time to get the optimum path. The improvement ratio regarding the path length is between 6% and 48%. While the path smoothness is improved in the range of 8% and 52%. In addition, GADPP reduces the required time to get the optimum path by 6% up to 47%.
Aberrant Excitatory–Inhibitory Synaptic Mechanisms in Entorhinal Cortex Microcircuits During the Pathogenesis of Alzheimer’s Disease

Abstract Synaptic dysfunction is widely proposed as an initial insult leading to the neurodegeneration observed in Alzheimer’s disease (AD). We hypothesize that the initial insult originates in the lateral entorhinal cortex (LEC) due to deficits in key interneuronal functions and synaptic signaling mechanisms, in particular, Wnt (Wingless/integrated). To investigate this hypothesis, we utilized the first knock-in mouse model of AD (AppNL-F/NL-F), expressing a mutant form of human amyloid-β (Aβ) precursor protein. This model shows an age-dependent accumulation of Aβ, neuroinflammation, and neurodegeneration. Prior to the typical AD pathology, we showed a decrease in canonical Wnt signaling activity first affecting the LEC in combination with synaptic hyperexcitation and severely disrupted excitatory–inhibitory inputs onto principal cells. This synaptic imbalance was consistent with a reduction in the number of parvalbumin-containing (PV) interneurons, and a reduction in the somatic inhibitory axon terminals in the LEC compared with other cortical regions. However, targeting GABAA receptors on PV cells using allosteric modulators, diazepam, zolpidem, or a nonbenzodiazepine, L-838,417 (modulator of α2/3 subunit-containing GABAA receptors), restored the excitatory–inhibitory imbalance observed at principal cells in the LEC. These data support our hypothesis, providing a rationale for targeting the synaptic imbalance in the LEC for early stage therapeutic intervention to prevent neurodegeneration in AD.
An anthropometry-based equation of fat mass percentage as a valid discriminator of obesity

Abstract Objective To develop a new predictive equation for fat mass percentage (%FM) based on anthropometric measurements and to assess its ability to discriminate between obese and non-obese individuals. Design Cross-sectional study. Setting Mexican adults. Participants Adults (n 275; 181 women) aged 20–63 years with BMI between 17·4 and 42·4 kg/m2. Results Thirty-seven per cent of our sample was obese using %FM measured by air-displacement plethysmography (BOD POD®; Life Measurement Instruments). The fat mass was computed from the difference between weight and fat-free mass (FFM). FFM was estimated using an equation obtained previously in the study from weight, height and sex of the individuals. The %FM estimated from the obtained FFM showed a sensitivity of 90·3 (95 % CI 86·8, 93·8) % and a specificity of 58·0 (95 % CI 52·1, 63·8) % in the diagnosis of obesity. Ninety-three per cent of participants with obesity and 65 % of participants without obesity were correctly classified. Conclusions The anthropometry-based equation obtained in the present study could be used as a screening tool in clinical and epidemiological studies not only to estimate the %FM, but also to discriminate the obese condition in populations with similar characteristics to the participant sample.
TP53 Mutation and Its Prognostic Significance in Waldenstrom's Macroglobulinemia

Purpose: TP53 is a tumor-suppressor gene that functions as a regulator influencing cellular responses to DNA damage, and TP53 alterations are associated with pejorative outcome in most B-lymphoid disorders. Little is known regarding TP53 alteration in Waldenstrom's macroglobulinemia (WM). Experimental Design: Here, we have explored the incidence of TP53 alteration using Sanger sequencing and ultradeep-targeted sequencing in 125 WM and 10 immunoglobulin M (IgM) monoclonal gammopathy of undetermined significance (MGUS), along with the clinical features and the associated genomic landscape using single-nucleotide polymorphism array and mutational landscape in an integrative study. Results: Overall, we have identified alteration of TP53 locus including mutation, deletion, and copy-neutral LOH in 11.2% of WM. TP53 mutation was acquired in 7.3% of patients with WM at diagnosis, being absent in IgM MGUS, and was highly correlated to deletion 17p. No correlation with CXCR4 mutations was observed. Patients with TP53 alteration had a greater number of genomic abnormalities. Importantly, WM with TP53 alteration had a significantly shorter overall survival, particularly in symptomatic WM, and independently of the international prognostic scoring system for Waldenstrom macroglobulinemia (IPSSWM) score. Specific treatment for WM with TP53 may have to be studied. Nutlin-3a–targeted p53 signaling induced cytotoxicity preclinically, along with new compounds such as ibrutinib, PrimaMet, or CP31398 that bypass p53 pathway in WM, paving the path for future treatment-tailored options. Conclusions: Our results highlight the clinical significance of detection of TP53 alteration in WM to determine the prognosis of WM and guide the treatment choice.

Mortality and Kidney Transplantation Outcomes Among Hepatitis C Virus-Seropositive Maintenance Dialysis Patients: A Retrospective Cohort Study.

RATIONALE & OBJECTIVE Hepatitis C virus (HCV) infection is common among maintenance dialysis patients. Few studies have examined both dialysis survival and transplantation outcomes for HCV-seropositive patients because registry data sets lack information for HCV serostatus. STUDY DESIGN Retrospective cohort study. SETTING & PARTICIPANTS Adult long-term dialysis patients treated by a US national dialysis provider between January 1, 2004, and December 31, 2014. EXPOSURE HCV antibody serostatus obtained as part of clinical data from a national dialysis provider. OUTCOMES Mortality on dialysis therapy, entry onto the kidney transplant waiting list, kidney transplantation, and estimated survival benefit from kidney transplantation versus remaining on the waitlist. ANALYTICAL APPROACH After linking clinical data with data from the Organ Procurement and Transplantation Network, Cox and cause-specific hazards regression were implemented to estimate the associations between HCV seropositivity and mortality, as well as entry onto the kidney transplant waitlist. Cox regression was also used to estimate the survival benefit from transplantation versus dialysis among HCV-seropositive individuals. RESULTS Among 442,171 dialysis patients, 31,624 (7.2%) were HCV seropositive. HCV seropositivity was associated with a small elevation in the rate of death (adjusted HR [aHR], 1.09; 95% CI, 1.07-1.11) and a substantially lower rate of entry onto the kidney transplant waitlist (subdistribution HR [sHR], 0.67; 95% CI, 0.61-0.74). Once wait-listed, the kidney transplantation rate was not different for HCV-seropositive (sHR 1.10; 95% CI, 0.96-1.27) versus HCV-seronegative patients. HCV-seropositive patients lived longer with transplantation (aHR at 3 years, 0.42; 95% CI, 0.27-0.63). Receiving an HCV-seropositive donor kidney provided a survival advantage at the 2-year posttransplantation time point compared to remaining on dialysis therapy waiting for an HCV-negative kidney. LIMITATIONS No data for HCV viral load or liver biopsy. CONCLUSIONS HCV-seropositive patients experience reduced access to the kidney transplantation waitlist despite deriving a substantial survival benefit from transplantation. HCV-seropositive patients should consider foregoing HCV treatment while accepting kidneys from HCV-infected donors to facilitate transplantation and prolong survival.
Problematic Eating Behaviors Are More Prevalent in African American Women Who Are Overweight or Obese Than African American Women Who Are Lean or Normal Weight

Problematic eating behaviors such as overeating and loss of control over consumption can lead to obesity. Problematic eating behaviors among women of differing body mass indexes were explored through focus group methodology, the Palatable Eating Motives Scale (PEMS), and a taste test in a sample of low-income African American women (n = 45). Women who were overweight or obese (W-O/O) reported more problematic eating behaviors including eating in the absence of hunger, frequent overeating, and increased food thoughts than women who were lean or normal weight (W-L/N). The W-O/O appear to possess more problematic eating behaviors than W-L/N.
Detection of anomalous nitrogen dioxide (NO2) concentration in urban air of India using proximity and clustering methods

ABSTRACT Owing to accurate future air quality estimates, need for detecting the anomalously high increase in concentration of pollutants cannot be adjourned. Plentiful approaches were proposed in the past to substantially determine the abnormal conditions, but most of the statistical approaches were computationally expensive and ignored the false alarm ratios. Thus, a hybrid of proximity- and clustering-based anomaly detection approaches to identify anomalies in the air quality data is suggested in this work. The Gaussian distribution property of the real-world data set is utilized further to segregate out anomalies. The results depicted twofold advantages of our approach, by efficient extraction of anomalies and with increased accuracy by reducing the number of false alarms. Specifically, the presence of NO2 concentration in air is investigated in this work, considering its constant increase over decades as well as its inevitable health risks. Furthermore, spatiotemporal segments with anomalously high NO2 concentrations for 14 residential, industrial, and commercial areas of five cities in India are extracted. To validate the results, a comparative analysis with existing approaches of anomaly detection and with two benchmark data sets is performed. Results showed that our method outperformed the existing methods of anomaly detection, when evaluated over metrics such as sensitivity, miss rate, and false alarms. Further, a detailed analysis of extracted anomalies and a detailed discussion about the factors responsible for such anomalies are presented in this work. This study is helpful in educating government and people about spatiotemporal, geographical, and economic conditions responsible for anomalously high NO2 concentrations in air. Implications: Using our methodology, days with extremely high concentration of any pollutant in air, at any particular location, can be extracted. The reasons for such extremely high pollutant concentration on particular days of a year can be studied and preventive measures can be taken by the government. Thus, by identification of causes of anomalies, future similar events can be avoided. This would also help in people’s decision making in case such events occur in the future.
Geriatric nutritional risk index predicts all‐cause deaths in heart failure with preserved ejection fraction

The objective of the study was to evaluate whether the geriatric nutritional risk index (GNRI) at discharge may be helpful in predicting the long‐term prognosis of patients hospitalized with heart failure (HF) with preserved ejection fraction (HFpEF, left ventricular ejection fraction ≥50%), a common HF phenotype in the elderly.
