The burden of illness of hepatorenal syndrome (HRS) in the United States: a retrospective analysis of electronic health records

Abstract Objectives: Hepatorenal Syndrome (HRS) is characterized by renal failure in patients with advanced chronic liver disease (CLD) and is the leading cause of hospitalizations in CLD. This study examines the clinical and economic burden, outcomes, and unmet need of HRS treatment in US hospitals. Method: A retrospective cohort study was conducted based on a large electronic health records database (Cerner HealthFacts) with records for hospitalized HRS patients from January 2009–June 2015. Demographics, clinical characteristics, treatment patterns, and economic outcomes were analyzed. Prognostic indicators of cirrhosis, kidney injury, end-stage liver disease, and acute-on-chronic liver failure were used to determine mortality risk. Results: A total of 2,542 patients hospitalized with HRS were identified (average age = 57.9 years, 61.8% males, 74.2% Caucasian), with an average total hospital charge of $91,504 per patient and a mean length of stay (LOS) of 30.5 days. The mortality rate was 36.9% with 8.9% of patients discharged to hospice. Of all patients, 1,660 patients had acute kidney injury, 859 with Stage 3 disease, and 26.7% had dialysis. The 30-day readmission rate was 33.1%, 41% of which were unplanned. Nearly one-third of study patients had commercial insurance (30.2%), followed by Medicare (29.9%); hospital charges varied by LOS, receipt of dialysis, and discharge status. Regression analysis demonstrated that HRS costs are associated with LOS, dialysis, and hospital mortality. Conclusion: HRS is associated with poor outcomes and high hospital costs. Analysis of HRS cost drivers demonstrated an unmet need for additional treatment options to improve outcomes in this patient population.
SnS2 Nanosheets/H-TiO2 Nanotube Arrays as a Type II Heterojunctioned Photoanode for Photoelectrochemical Water Splitting.

Improving the separation efficiency of photogenerated electron-hole pairs and the conductivity of electrons to photoanode substrates are critical to achieve high-performance photoelectrochemical (PEC) water splitting. Here, a SnS2 /H-TiO2 /Ti heterojunction photoanode was fabricated with SnS2 nanosheets vertically grown on hydrogen-treated TiO2 (H-TiO2 ) nanotube arrays on a Ti substrate. It showed a significantly enhanced photocurrent of 4.0 mA cm-2 at 1.4 V (vs. reversible hydrogen electrode) under AM 1.5 G illumination, 70 times higher than that of SnS2 /TiO2 /Ti. Kelvin probe force microscopy measurements indicated that photogenerated electrons could be easily transported through the SnS2 /H-TiO2 interface but not through the SnS2 /TiO2 interface. Through hydrogen treatment, defects were created in H-TiO2 nanotubes to convert type I junctions to type II with SnS2 nanosheets. As a result, a high efficiency of electron-hole separation at the SnS2 /H-TiO2 interface and a high electron conductivity in H-TiO2 nanotubes were achieved and improved PEC performance. These findings show an effective route towards high-performance photoelectrodes for water splitting.
Effect of surface-bound sulfide on oxygen reduction reaction on Pt: Breaking the scaling relationship and mechanistic insights.

A combined in situ electrochemical attenuated total reflection-surface enhanced IR absorption spectroscopy, microkinetic simulation, and density functional theory calculation study shows that not only can the adsorbed sulfide disproportionally affect the surface binding of OOH* (EOOH* ) vs OH* (EOH* ), i.e., breaking the original scaling relationship of pure metals (Ir, Pd, Pt, Au), to enhance oxygen reduction reaction (ORR) activity but can also be used as a reaction pathway alternating species to help deepen our mechanistic understanding of ORR.
Syncytin-1 and Glial Cells Missing a: Hypoxia-Induced Deregulated Gene Expression along with Disordered Cell Fusion in Primary Term Human Trophoblasts

Background/Aims: Pre-eclampsia, a major cause of perinatal morbidity, is characterized by alterations in placental oxygen availability and trophoblast differentiation. We investigated how different levels of hypoxia alter the expression of syncytin-1, glial cells missing a (GCMa) and syncytin-1 receptor ASCT2 and affect syncytialization in primary term human trophoblasts. Methods: Cells were incubated at 1, 3, 6 and 21% O2 for 24, 48 and 72 h with or without cyclic adenosine monophosphate (cAMP). Gene expression was analyzed by real-time PCR. Syncytialization was assessed using β-human chorionic gonadotropin measurement and desmoplakin immunostaining. Results: Following incubation with cAMP at 21% O2, peak gene expression of syncytin-1 and GCMa was found after 24 h along with syncytium formation at 72 h. Conversely, incubation at 1% O2 led to a time-dependent reduction of GCMa and syncytin-1 at the transcriptional level. Cell fusion occurred at 21 and 6% O2 and was suppressed at 1% O2. ASCT2 mRNA levels were preserved at normoxia and downregulated at 1% O2 after 48 h. Conclusion: Our data support the premise that the expression of GCMa and syncytin-1 precedes syncytialization of trophoblasts, e.g. at 6% O2, which is assumed to resemble physiological conditions. Severe hypoxia is associated with reduced GCMa and syncytin-1 transcripts and altered fusion of primary trophoblasts.
Complete mitochondrial genome of Diptychus maculatus (Cypriniformes: Cyprinidae: Schizothoracinae)

Abstact The complete mitogenome sequence of the mitochondrial genome of Diptychus maculatus was amplified and analyzed in this study. It was 16,895 bp in length and contained 13 protein-coding genes, 2 ribosomal RNA genes, 22 tRNA and 1 control region. Most of the genes were encoded on the heavy strand except for eight tRNA genes and DN6. The overall base composition of the complete mtDNA was 27.80% A, 26.70% T, 19.01% G and 26.49% C. A 312 bp-long sequence containing a tandem repeat array (37 bp) was found between tRNAThr and tRNAPro.
Unconventional mental health treatment: reexamining the racial-ethnic disparity in treatment-seeking behavior.

OBJECTIVE The aim of this study was to examine whether a more inclusive definition of mental health treatment that incorporates unconventional treatment may partially account for the racial disparity in treatment-seeking behavior. METHODS Using 2005-2007 pooled data (N=102,749) from the National Survey on Drug Use and Health (NSDUH), logistic regression models were used to examine the relationship between race (non-Hispanic white, non-Hispanic black, and Hispanic) and the type of mental health treatment sought. Treatment types were classified as conventional care (outpatient or inpatient), psychotropic medication, or unconventional treatment. Unconventional treatment was further classified as complementary and alternative medicine or parochial care, defined as treatment that appeals to a specific religious group that is provided at no cost outside a health delivery system. RESULTS Compared with whites, blacks had 53% lower odds and Hispanics had 41% lower odds of seeking any type of mental health treatment in the past year. Both blacks and Hispanics were significantly less likely to report use of any single type of conventional or unconventional mental health treatment other than parochial care. Blacks had 60% greater odds and Hispanics had 36% greater odds than whites of using parochial care only. CONCLUSIONS Although blacks and Hispanics were more likely than whites to use parochial mental health treatment, accounting for use of this type of unconventional treatment did not explain the racial disparity in treatment-seeking behavior.
ARE PSYCHOTIC PSYCHOPATHOLOGY AND NEUROCOGNITION ORTHOGONAL? A SYSTEMATIC REVIEW OF THEIR ASSOCIATIONS

A systematic review (58 studies, 5,009 individuals) is presented of associations between psychopathological dimensions of psychosis and measures of neurocognitive impairment in subjects with a lifetime history of nonaffective psychosis. Results showed that negative and disorganized dimensions were significantly but modestly associated with cognitive deficits (correlations from -.29 to -.12). In contrast, positive and depressive dimensions of psychopathology were not associated with neurocognitive measures. The patterns of association for the 4 psychosis dimensions were stable across neurocognitive domains and were independent of age, gender, and chronicity of illness. In addition, significantly higher correlations were found for the negative dimension in relation to verbal fluency (p = .005) and for the disorganized dimension in relation to reasoning and problem solving (p = .004) and to attention/vigilance (p = .03). Psychotic psychopathology and neurocognition are not entirely orthogonal, as heterogeneity in nonaffective psychosis is weakly but meaningfully associated with measures of neurocognition. This association suggests that differential latent cerebral mechanisms underlie the cluster of disorganized and negative symptoms versus that of positive and affective symptoms.
Saturated Fat Intake Is Associated with Lung Function in Individuals with Airflow Obstruction: Results from NHANES 2007–2012

Nutritional status is a well-recognized prognostic indicator in chronic obstructive pulmonary disease (COPD); however, very little is known about the relationship between lung function and saturated fat intake. We used data from the cross-sectional National Health and Nutrition Examination Surveys (NHANES) to assess the relationship between saturated fatty acid (SFA) intake and lung function in the general US adult population. Adults in NHANES (2007–2012) with pre-bronchodilator spirometry measurements and dietary SFA intake were included. Primary outcomes were lung function including forced expiratory volume in one second (FEV1), FEV1, forced vital capacity (FVC), FEV1/FVC ratio, percent predicted FEV1 and percent predicted FVC. Multivariable regression models in the general population as well as those with spirometry-defined airflow obstruction were used to assess the relationship between lung function measurements and dietary SFA intake after adjustment for confounders. 11,180 eligible participants were included in this study. Univariate analysis revealed a statistically significant positive association between total SFA intake and lung function outcomes; however, these relationships were attenuated after adjustment for covariates. A secondary analysis of individuals with spirometry-defined airflow obstruction (FEV1/FVC < 0.7) revealed that a lower intake of SFA was associated with reduced FEV1 (β = −126.4, p = 0.04 for quartile 1 vs. quartile 4), FVC (β = −165.8. p = 0.01 for quartile 1 vs. quartile 4), and percent predicted FVC (β = −3.3. p = 0.04 for quartile 1 vs. quartile 4), after adjustment for relevant confounders. No associations were observed for the FEV1/FVC ratio and percent predicted FEV1. It is possible that characteristics such as food source and fatty acid chain length may influence associations between saturated fatty acid intake and health outcomes.
Autophagy And Apoptosis Specifc Knowledgebases-Guided Systems Pharmacology Drug Research.

BACKGROUNDS Autophagy and apoptosis are the basic physiological processes in cells that clean up aged and mutant cellular components or even the entire cells. Both autophagy and apoptosis are disrupted in most major diseases such as cancer and neurological disorders. Recently, increasing attention is paid to understand the crosstalk between autophagy and apoptosis due to their tightly synergetic or opposite functions in several pathological processes. OBJECTIVE This study aims to assist autophagy and apoptosis-related drug research, clarify the intense and complicated connections between two processes, and provide a guide for novel drug development. METHOD We established two chemical-genomic databases which are specifically designed for autophagy and apoptosis, including autophagy- and apoptosis-related proteins, pathways and compounds. We then performed network analysis on the apoptosis- and autophagy-related proteins and investigated the full protein-protein interaction (PPI) network of these two closely connected processes for the first time. RESULTS The overlapping targets we discovered show a more intense connection with each other than other targets in the full network, indicating a better efficacy potential for drug modulation. We also found that Death-associated protein kinase 1 (DAPK1) is a critical point linking autophagy- and apoptosis-related pathways beyond the overlapping part, and this finding may reveal some delicate signaling mechanism of the process. Finally, we demonstrated how to utilize our integrated computational chemogenomics tools on in silico target identification for small molecules capable of modulating autophagy- and apoptosis-related pathways. CONCLUSION The knowledgebases for apoptosis and autophagy and the integrated tools will accelerate our work in autophagy and apoptosis-related research and can be useful sources for information searching, target prediction, and new chemical discovery.
Ontogeny of symbiont community structure in two carotenoid‐rich, viviparous marine sponges: comparison of microbiomes and analysis of culturable pigmented heterotrophic bacteria

Summary Marine sponges harbour diverse communities of microbes. Mechanisms used to establish microbial symbioses in sponges are poorly understood, and the relative contributions of horizontal and vertical transmission are unknown for most species. We examined microbial communities in adults and larvae of carotenoid‐rich Clathria prolifera and Halichondria bowerbanki from the mid‐Atlantic region of the eastern United States. We sequenced microbiomes from larvae and their mothers and seawater (16S rRNA gene sequencing), and compared microbial community characteristics between species and ambient seawater. The microbial communities in sponges were significantly different than those found in seawater, and each species harboured a distinctive microbiome. Larval microbiomes exhibited significantly lower richness compared with adults, with both sponges appearing to transfer to larvae a particular subset of the adult microbiome. We also surveyed culturable bacteria isolated from larvae of both species. Due to conspicuous coloration of adults and larvae, we focused on pigmented heterotrophic bacteria. We found that the densities of bacteria, in terms of colony‐forming units and pigmented heterotrophic bacteria, were higher in larvae than in seawater. We identified a common mode of transmission (vertical and horizontal) of microbes in both sponges that might differ between species.
PET Radiopharmaceuticals for Specific Bacteria Imaging: A Systematic Review

Background: Bacterial infections are still one of the main factors associated with mortality worldwide. Many radiopharmaceuticals were developed for bacterial imaging, both with single photon emission computed tomography (SPECT) and positron emission tomography (PET) isotopes. This review focuses on PET radiopharmaceuticals, performing a systematic literature review of published studies between 2005 and 2018. Methods: A systematic review of published studies between 2005 and 2018 was performed. A team of reviewers independently screened for eligible studies. Because of differences between studies, we pooled the data where possible, otherwise, we described separately. Quality of evidence was assessed by Quality Assessment of Diagnostic Accuracy Studies (QUADAS) approach. Results: Eligible papers included 35 published studies. Because of the heterogeneity of animal models and bacterial strains, we classified studies in relation to the type of bacterium: Gram-positive, Gram-negative, Gram-positive and negative, others. Conclusions: Results highlighted the availability of many promising PET radiopharmaceuticals for bacterial imaging, despite some bias related to animal selection and index test, but few have been translated to human subjects. Results showed a lack of standardized infection models and experimental settings.
Two amino acid sequences direct Aspergillus nidulans protein kinase C (PkcA) localization to hyphal apices and septation sites

The Aspergillus nidulans ortholog of protein kinase C (pkcA) is involved in the organism’s putative cell wall integrity (CWI) pathway, and PkcA also is highly localized at growing tips and forming septa. In the present work we identify the regions within PkcA that are responsible for its localization to hyphal tips and septation sites. To this end, we used serially truncated pkcA constructs and expressed them as green fluorescent protein (GFP) chimeras and identified two regions that direct PkcA localization. The first region is a 10 amino-acid sequence near the carboxyl end of the C2 domain that is required for localization to hyphal tips. Proteins containing this sequence also localize to septation sites. A second region between C2 and C1B (encompassing C1A) is sufficient for localization to septation sites but not to hyphal tips. We also report that localization to hyphal tips and septation sites alone is not sufficient for truncated constructs to complement hypersensitivity to the cell wall compromising agent calcofluor white in a strain bearing a mutation in the pkcA gene. Taken together, these results suggest that localization and stress response might be independent.
When Loading Working Memory Reduces Distraction: Behavioral and Electrophysiological Evidence from an Auditory-Visual Distraction Paradigm

The sensitivity of involuntary attention to top-down modulation was tested using an auditory-visual distraction task and a working memory (WM) load manipulation in subjects performing a simple visual classification task while ignoring contingent auditory stimulation. The sounds were repetitive standard tones (80%) and environmental novel sounds (20%). Distraction caused by the novel sounds was compared across a 1-back WM condition and a no-memory control condition, both involving the comparison of two digits. Event-related brain potentials (ERPs) to the sounds were recorded, and the N1/MMN (mismatch negativity), novelty-P3, and RON components were identified in the novel minus standard difference waveforms. Distraction was reduced in the WM condition, both behaviorally and as indexed by an attenuation of the late phase of the novelty-P3. The transient/change detection mechanism indexed by MMN was not affected by the WM manipulation. Sustained, slow frontal and parietal waveforms related to WM processes were found on the standard ERPs. The present results indicate that distraction caused by irrelevant novel sounds is reduced when a WM component is involved in the task, and that this modulation by WM load takes place at a late stage of the orienting response, all in all confirming that involuntary attention is under the control of top-down mechanisms. Moreover, as these results contradict predictions of the load theory of selective attention and cognitive control, it is suggested that the WM load effects on distraction depend on the nature of the distractor-target relationships.
Inhibition of the deubiquitinase USP9x induces pre-B cell homeobox 1 (PBX1) degradation and thereby stimulates prostate cancer cell apoptosis

Chemoresistance is a leading obstacle in effective management of advanced prostate cancer (PCa). A better understanding of the molecular mechanisms involved in PCa chemoresistance could improve treatment of patients with PCa. In the present study, using immune histochemical, chemistry, and precipitation assays with cells from individuals with benign or malignant prostate cancer or established PCa cell lines, we found that the oncogenic transcription factor pre-B cell leukemia homeobox-1 (PBX1) promotes PCa cell proliferation and confers to resistance against common anti-cancer drugs such as doxorubicin and cisplatin. We observed that genetic PBX1 knockdown abrogates this resistance, and further experiments revealed that PBX1 stability was modulated by the ubiquitin-proteasomal pathway. To directly probe the impact of this pathway on PBX1 activity, we screened for PBX1-specific deubiquitinases (Dubs) and found that ubiquitin-specific peptidase 9 X-linked (USP9x) interacted with and stabilized the PBX1 protein by attenuating its Lys-48–linked polyubiquitination. Moreover, the USP9x inhibitor WP1130 markedly induced PBX1 degradation and promoted PCa cell apoptosis. The results in this study indicate that PBX1 confers to PCa chemoresistance and identify USP9x as a Dub of PBX1. We concluded that targeting the USP9x/PBX1 axis could be a potential therapeutic strategy for managing advanced prostate cancer.
Cardiovascular events in hospitalised patients with schizophrenia: a survival analysis

Abstract Objective: To evaluate the occurrence of cardiovascular (CV), cerebrovascular events and mortality rates, and compare the predictive ability of two scores, Framingham Risk Score (FRS) and Atherosclerotic Cardiovascular Disease (ASCVD), of detecting a cardiovascular event in a cohort of schizophrenic patients. Methods: A cohort of 329 hospitalised schizophrenic patients is being monitored since 1 January 2013. Patients’ file review was performed to detect the CV events of interest. Results: Out of the 329 patients with schizophrenia, with a mean study follow-up of 41.07 ± 12.55 months, 29 cardiovascular events were recorded; of those events, we recorded 4 myocardial infarction, 1 stroke, 6 heart failure and 18 cardiovascular deaths. The major composite outcome of cardiovascular events rate was equal to 9.0 per 100 patient-years. The secondary composite outcome of cardiovascular events rate was equal to 7.2 per 100 patient-years (0.072 events per patient). The association between survival curve of patients with high and low CVR according to FRS score tended to significance (RR = 1.90, p = .078). Patients classified as high cardiovascular risk according to ASCVD presented a reduced cardiovascular survival (RR = 3.35, p = .005). Conclusion: The ASCVD items should be included in the medical assessment in any patient with severe mental illness. Key points The major composite outcome of cardiovascular events rate was equal to 9.0 per 100 patient-years.
