Rigorous Screened Interactions for Realistic Correlated Electron Systems.

We derive a widely applicable first-principles approach for determining two-body, static effective interactions for low-energy Hamiltonians with quantitative accuracy. The algebraic construction rigorously conserves all instantaneous two-point correlation functions in a chosen model space at the level of the random phase approximation, improving upon the traditional uncontrolled static approximations. Applied to screened interactions within a quantum embedding framework, we demonstrate these faithfully describe the relaxation of local subspaces via downfolding high-energy physics in molecular systems, as well as enabling a systematically improvable description of the long-range plasmonic contributions in extended graphene.

Autologous cell immunotherapy (IGV-001) with IGF-1R antisense oligonucleotide in newly diagnosed glioblastoma patients.

Standard-of-care first-line therapy for patients with newly diagnosed glioblastoma (ndGBM) is maximal safe surgical resection, then concurrent radiotherapy and temozolomide, followed by maintenance temozolomide. IGV-001, the first product of the Goldspire™ platform, is a first-in-class autologous immunotherapeutic product that combines personalized whole tumor-derived cells with an antisense oligonucleotide (IMV-001) in implantable biodiffusion chambers, with the intent to induce a tumor-specific immune response in patients with ndGBM. Here, we describe the design and rationale of a randomized, double-blind, phase IIb trial evaluating IGV-001 compared with placebo, both followed by standard-of-care treatment in patients with ndGBM. The primary end point is progression-free survival, and key secondary end points include overall survival and safety.

Glioblastoma (GBM) is a fast-growing brain tumor that happens in about half of all gliomas. Surgery is the first treatment for patients with newly diagnosed GBM, followed by the usual radiation and chemotherapy pills named temozolomide. Temozolomide pills are then given as a long-term treatment. The outcome for the patient with newly diagnosed GBM remains poor. IGV-001 is specially made for each patient. The tumor cells are removed during surgery and mixed in the laboratory with a small DNA, IMV-001. This mix is the IGV-001 therapy that is designed to give antitumor immunity against GBM. IGV-001 is put into small biodiffusion chambers that are irradiated to stop the growth of any tumor cells in the chambers. In the phase IIb study, patients with newly diagnosed GBM are chosen and assigned to either the IGV-001 or the placebo group. A placebo does not contain any active ingredients. The small biodiffusion chambers containing either IGV-001 or placebo are surgically placed into the belly for 48 to 52 h and then removed. Patients then receive the usual radiation and chemotherapy treatment. Patients must be adults aged between 18 and 70 years. Patients also should be able to care for themselves overall, but may be unable to work or have lower ability to function. Patients with tumors on both sides of the brain are not eligible. The main point of this study is to see if IGV-001 helps patients live longer without making the illness worse compared with placebo. Clinical Trial Registration: NCT04485949 (ClinicalTrials.gov).

A biologic-device combination product delivering tumor-derived antigens elicits immunogenic cell death-associated immune responses against glioblastoma.

BACKGROUND: IGV-001 is a personalized, autologous cancer cell-based immunotherapy conceived to deliver a tumor-derived antigenic payload in the context of immunostimulatory signals to patients with glioblastoma (GBM). IGV-001 consists of patient-derived GBM cells treated with an antisense oligodeoxynucleotide against insulin-like growth factor 1 receptor (IGF1R) and placed in proprietary biodiffusion chambers (BDCs). The BDCs are then exposed to 5-6 Gy radiation and implanted at abdominal sites for ~48 hours. IGV-001 has previously been shown to be generally safe with promising clinical activity in newly diagnosed GBM patients. METHODS: Mouse (m) or human (h) variants of IGV-001 were prepared using GL261 mouse GBM cells or human GBM cells, respectively. BDCs containing vehicle or mIGV-001 were implanted in the flanks of C57BL/6 albino female mice in preventative and therapeutic experiments, optionally in combination with a programmed cell death 1 (PD-1) blocker. Bioactivity of the general approach was also measured against hepatocellular carcinoma Hepa 1-6 cells. Mice were followed for the growth of subsequently implanted or pre-existing tumors and survival. Draining lymph nodes from mice receiving mIGV-001 were immunophenotyped. mIGV-001 and hIGV-001 were analyzed for extracellular ATP and high mobility group box 1 (HMGB1) as indicators of immunogenic cell death (ICD), along with flow cytometric analysis of viability, surface calreticulin, and reactive oxygen species. Stress and cell death-related pathways were analyzed by immunoblotting. RESULTS: IGV-001 causes oxidative and endoplasmic reticulum stress in GL261 cells, resulting in a cytotoxic response that enables the release of antigenic material and immunostimulatory, ICD-associated molecules including ATP and HMGB1 from BDCs. Immunophenotyping confirmed that IGV-001 increases the percentage of dendritic cells, as well as effector, and effector memory T cells in BDC-draining lymph nodes. Consistent with these observations, preventative IGV-001 limited tumor progression and extended overall survival in mice intracranially challenged with GL261 cells, a benefit that was associated with an increase in tumor-specific T cells with effector features. Similar findings were obtained in the Hepa 1-6 model. Moreover, therapeutically administered IGV-001 combined with PD-1 delayed progression in GBM-bearing mice. CONCLUSIONS: These results support treatment with IGV-001 to induce clinically relevant ICD-driven anticancer immune responses in patients with GBM.

Identification of a ß-arrestin-biased negative allosteric modulator for the ß2-adrenergic receptor.

Catecholamine-stimulated ß2-adrenergic receptor (ß2AR) signaling via the canonical Gs-adenylyl cyclase-cAMP-PKA pathway regulates numerous physiological functions, including the therapeutic effects of exogenous ß-agonists in the treatment of airway disease. ß2AR signaling is tightly regulated by GRKs and ß-arrestins, which together promote ß2AR desensitization and internalization as well as downstream signaling, often antithetical to the canonical pathway. Thus, the ability to bias ß2AR signaling toward the Gs pathway while avoiding ß-arrestin-mediated effects may provide a strategy to improve the functional consequences of ß2AR activation. Since attempts to develop Gs-biased agonists and allosteric modulators for the ß2AR have been largely unsuccessful, here we screened small molecule libraries for allosteric modulators that selectively inhibit ß-arrestin recruitment to the receptor. This screen identified several compounds that met this profile, and, of these, a difluorophenyl quinazoline (DFPQ) derivative was found to be a selective negative allosteric modulator of ß-arrestin recruitment to the ß2AR while having no effect on ß2AR coupling to Gs. DFPQ effectively inhibits agonist-promoted phosphorylation and internalization of the ß2AR and protects against the functional desensitization of ß-agonist mediated regulation in cell and tissue models. The effects of DFPQ were also specific to the ß2AR with minimal effects on the ß1AR. Modeling, mutagenesis, and medicinal chemistry studies support DFPQ derivatives binding to an intracellular membrane-facing region of the ß2AR, including residues within transmembrane domains 3 and 4 and intracellular loop 2. DFPQ thus represents a class of biased allosteric modulators that targets an allosteric site of the ß2AR.

The forensic assessment of dissociation: Distinguishing real from the unreal.

Because a wide range of disorders incorporate dissociative symptoms, evaluators should be familiar with evidence-based approaches to evaluating dissociation claims in the clinical and forensic context. This article provides specific guidelines for practitioners when conducting a forensic assessment of individuals who report dissociative symptoms. We review the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition disorders that include dissociation as a symptom, highlight how to distinguish genuine versus atypical symptoms of dissociative identity disorder, and summarize strengths and weaknesses of structured assessments in the evaluation of dissociative claims.

A "moment-conserving" reformulation of GW theory.

We show how to construct an effective Hamiltonian whose dimension scales linearly with system size, and whose eigenvalues systematically approximate the excitation energies of GW theory. This is achieved by rigorously expanding the self-energy in order to exactly conserve a desired number of frequency-independent moments of the self-energy dynamics. Recasting GW in this way admits a low-scaling O[N4] approach to build and solve this Hamiltonian, with a proposal to reduce this further to O[N3]. This relies on exposing a novel recursive framework for the density response moments of the random phase approximation, where the efficient calculation of its starting point mirrors the low-scaling approaches to compute RPA correlation energies. The frequency integration of GW, which distinguishes so many different GW variants, can be performed without approximation directly in this moment representation. Furthermore, the solution to the Dyson equation can be performed exactly, avoiding analytic continuation, diagonal approximations, or iterative solutions to the quasiparticle equation, with the full-frequency spectrum obtained from the complete solution of this effective static Hamiltonian. We show how this approach converges rapidly with respect to the order of the conserved self-energy moments and is applied across the GW100 benchmark dataset to obtain accurate GW spectra in comparison to traditional implementations. We also show the ability to systematically converge all-electron full-frequency spectra and high-energy features beyond frontier excitations, as well as avoiding discontinuities in the spectrum, which afflict many other GW approaches.

11ß-HSD1 inhibition in men mitigates prednisolone-induced adverse effects in a proof-of-concept randomised double-blind placebo-controlled trial.

Glucocorticoids prescribed to limit inflammation, have significant adverse effects. As 11ß-hydroxysteroid dehydrogenase type 1 (11ß-HSD1) regenerates active glucocorticoid, we investigated whether 11ß-HSD1 inhibition with AZD4017 could mitigate adverse glucocorticoid effects without compromising their anti-inflammatory actions. We conducted a proof-of-concept, randomized, double-blind, placebo-controlled study at Research Unit, Churchill Hospital, Oxford, UK (NCT03111810). 32 healthy male volunteers were randomized to AZD4017 or placebo, alongside prednisolone treatment. Although the primary endpoint of the study (change in glucose disposal during a two-step hyperinsulinemic, normoglycemic clamp) wasn't met, hepatic insulin sensitivity worsened in the placebo-treated but not in the AZD4017-treated group. Protective effects of AZD4017 on markers of lipid metabolism and bone turnover were observed. Night-time blood pressure was higher in the placebo-treated but not in the AZD4017-treated group. Urinary (5aTHF+THF)/THE ratio was lower in the AZD4017-treated but remained the same in the placebo-treated group. Most anti-inflammatory actions of prednisolone persisted with AZD4017 co-treatment. Four adverse events were reported with AZD4017 and no serious adverse events. Here we show that co-administration of AZD4017 with prednisolone in men is a potential strategy to limit adverse glucocorticoid effects.

ß2 -Adrenoceptor agonist profiling reveals biased signalling phenotypes for the ß2 -adrenoceptor with possible implications for the treatment of asthma.

BACKGROUND AND PURPOSE: ß-Adrenoceptor agonists relieve airflow obstruction by activating ß2 -adrenoceptors, which are G protein-coupled receptors (GPCRs) expressed on human airway smooth muscle (HASM) cells. The currently available ß-adrenoceptor agonists are balanced agonists, however, and signal through both the stimulatory G protein (Gs )- and ß-arrestin-mediated pathways. While Gs signalling is beneficial and promotes HASM relaxation, ß-arrestin activation is associated with reduced Gs efficacy. In this context, biased ligands that selectively promote ß2 -adrenoceptor coupling to Gs signalling represent a promising strategy to treat asthma. Here, we examined several ß-adrenoceptor agonists to identify Gs -biased ligands devoid of ß-arrestin-mediated effects. EXPERIMENTAL APPROACH: Gs -biased ligands for the ß2 -adrenoceptor were identified by high-throughput screening and then evaluated for Gs interaction, Gi interaction, cAMP production, ß-arrestin interaction, GPCR kinase (GRK) phosphorylation of the receptor, receptor trafficking, ERK activation, and functional desensitization of the ß2 -adrenoceptor. KEY RESULTS: We identified ractopamine, dobutamine, and higenamine as Gs -biased agonists that activate the Gs /cAMP pathway upon ß2 -adrenoceptor stimulation while showing minimal Gi or ß-arrestin interaction. Furthermore, these compounds did not induce any receptor trafficking and had reduced GRK5-mediated phosphorylation of the ß2 -adrenoceptor. Finally, we observed minimal physiological desensitization of the ß2 -adrenoceptor in primary HASM cells upon treatment with biased agonists. CONCLUSION AND IMPLICATIONS: Our work demonstrates that Gs -biased signalling through the ß2 -adrenoceptor may prove to be an effective strategy to promote HASM relaxation in the treatment of asthma. Such biased compounds may also be useful in identifying the molecular mechanisms that determine biased signalling and in design of safer drugs.

Recovery in glioblastoma multiforme during inpatient rehabilitation is equivalent in first versus repeat resection: A 10-year retrospective analysis.

BACKGROUND: Inpatient rehabilitation improves function in people with brain tumors, including glioblastoma multiforme (GBM) but there are limited data on the impact of multiple resections on outcomes. We hypothesize that outcomes will be more favorable for those patients with a single resection when compared to those with more than one resection. OBJECTIVE: To examine functional outcomes in inpatient rehabilitation for people with GBM who underwent one or more resections prior to admission. DESIGN: Retrospective analysis. SETTING: Inpatient rehabilitation unit within a large, urban, academic medical center. PARTICIPANTS: Patients who were admitted to our institution for the treatment of initial GBM or GBM recurrence necessitating surgical resection or repeat resection. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE(S): Total FIM Change, Total Functional Independence Measure (FIM) Efficiency, Motor and Cognitive FIM efficiency, and proportion discharged home. RESULTS: From 2006 to 2016, 94 persons with GBM were admitted. Eight were readmissions classified as "repeat" and another seven transferred to the medical floor and excluded. Of the 79 patients included, 56 were first and 23 second resections, with a group mean age of 62.7 + 12.2 years and were 51% male. On analysis of covariance, change in FIM score from admission to discharge was insignificant between groups, adjusted for age and acute care length of stay (17.1 vs. 17.4, F[1, 75] = 0.027, P = .871). Likewise, the proportion of home discharge was not significant between groups (chi-square, 75.0% vs. 78.3%, P = .758). CONCLUSIONS: Patients who have undergone second resections for GBM are reasonable candidates for admission to the inpatient rehabilitation units despite carrying a poor prognosis and having multiple exposures to surgical morbidity. Factors to take into account are that candidates considered for a second resection may be relatively younger or healthier and therefore may perform better from a functional standpoint. In addition, postoperative steroid administration may play a role in the similarities the authors noted. A larger, multicenter study should validate our findings (limited by sample size and a single location) and identify factors predicting a successful outcome.

Long-term safety of the tafenoquine antimalarial chemoprophylaxis regimen: A 12-month, randomized, double-blind, placebo-controlled trial.

BACKGROUND: Tafenoquine is a long-acting 8-aminoquinoline approved for antimalarial prophylaxis for ≤6 months. Additional data is needed to establish the drug's longer-term safety profile, including potential ophthalmic or neuropsychiatric effects. METHOD: This was a randomized, double-blind, placebo-controlled trial in 600 healthy adults. Eligible subjects were randomized 1:1 to receive tafenoquine 200 mg weekly (antimalarial prophylactic regimen) or placebo for 52 weeks. Scheduled safety visits occurred at Weeks 4, 12, 24, 52 (dosing completed), and 64 (final follow-up). Safety assessments included ophthalmic changes, general and neuropsychiatric adverse events (AEs), and laboratory value changes. RESULTS: The percentage of subjects with a protocol-defined Serious Ophthalmic Safety Event was lower in the Tafenoquine Group (18.2%) versus the Placebo Group (19%, p = 0.308). There was no significant difference between the percentages of subjects with at least one AE in the Tafenoquine Group (91.0%) versus Placebo (89.9%, p = 0.65). Common AEs seen at a significantly higher incidence for tafenoquine included reversible cornea verticillata (54.5%) and nausea (13.0%), leading to 0.0% and 0.7% discontinuations. Psychiatric AEs occurred at similar percentages in both study groups. Reversible changes in hemoglobin, methemoglobin, creatinine, and blood urea nitrogen (BUN) were noted. CONCLUSIONS: This study supports the safety of extended 52-week tafenoquine prophylaxis. CLINICAL TRIAL REGISTRATION NUMBER/CLINICALTRIALS. GOV IDENTIFIER: NCT03320174.

Re/turning to soil: becoming one-bodied with the Earth.

This paper curates four experiential narratives and poetry by the five co-authors that illustrate epistemic and ontic shift from the Modern Western (ModWest) mindset to a holistic, embodied and animistic mindset. Coming from different cultural backgrounds, yet having been systemically influenced by the dominant ModWest views and values, each author has initiated an ongoing shift in consciousness, demonstrating how such transformations are possible. Affirming that a shift in consciousness is not simply a matter of cognitive change but is a thoroughly holistic process, the authors write in autobiographical narratives and poetry to capture and convey embodied and emplaced, experiential understanding and feelings, or 'felt sense.' Deep changes in the consciousness, such as these epistemic shifts, take the whole ensemble of "body + mind + heart + soul + spirit + the world" as the unit of change for learning. Through these writings, they sensuously and feelingly, existentially-and-spiritually and discursively explore possibilities of becoming one-bodied with the animate Earth. They call this the re-bonding project through which they address humanity's first-order bonding rupture between Humans and the Earth community.

Predicting the risk of developing type 2 diabetes in Chinese people who have coronary heart disease and impaired glucose tolerance.

AIMS: Robust diabetes risk estimates in Asian patients with impaired glucose tolerance (IGT) and coronary heart disease (CHD) are lacking. We developed a Chinese type 2 diabetes risk calculator using Acarbose Cardiovascular Evaluation (ACE) trial data. METHODS: There were 3105 placebo-treated ACE participants with requisite data for model development. Clinically relevant variables, and those showing nominal univariate association with new-onset diabetes (P < .10), were entered into BASIC (clinical variables only), EXTENDED (clinical variables plus routinely available laboratory results), and FULL (all candidate variables) logistic regression models. External validation was performed using the Luzhou prospective cohort of 1088 Chinese patients with IGT. RESULTS: Over median 5.0 years, 493 (15.9%) ACE participants developed diabetes. Lower age, higher body mass index, and use of corticosteroids or thiazide diuretics were associated with higher diabetes risk. C-statistics for the BASIC (using these variables), EXTENDED (adding male sex, fasting plasma glucose, 2-hour glucose, and HbA1c), and FULL models were 0.610, 0.757, and 0.761 respectively. The EXTENDED model predicted a lower 13.9% 5-year diabetes risk in the Luzhou cohort than observed (35.2%, 95% confidence interval 31.3%-39.5%, C-statistic 0.643). CONCLUSION: A risk prediction model using routinely available clinical variables can be used to estimate diabetes risk in Chinese people with CHD and IGT.

A patient-centric pathway for testicular cancer - A multicentre study investigating the uptake of semen cryopreservation and impact on treatment.

BACKGROUND: The option of semen cryopreservation following a diagnosis of testicular cancer shows a variable uptake with the option to cryopreserve before surgery often dependent on the preference of the treating clinician and the fertility laboratory resources available. OBJECTIVES: To assess whether the introduction of a patient-centric pathway for managing suspected testicular cancer increases the uptake of semen cryopreservation and the impact of this on surgical waiting times. MATERIALS AND METHODS: A multicentre retrospective analysis of patients treated as part of a patient-centric pathway was conducted for suspected testicular cancer at two specialist centres within a one-stop testicular clinic. Clinical information, including semen cryopreservation acceptance rate, time intervals to surgery and CT scan, TNM stage, histology and age, was recorded from an institutional database. RESULTS: Eighty nine patients (median age: 34 years (range: 14-89)) underwent orchidectomy for suspected testicular cancer over a 15-month period after the introduction of a patient-centric testicular cancer pathway at two UK centres. The overall uptake of semen cryopreservation was 68.5% (n = 61) with all men under the age of 33 years accepting this option. A microdissection oncoTESE was performed in 9/61 (14.8%) patients who attempted cryopreservation but were found to be azoospermic. Pre-operative CT imaging was completed for 85.4% of patients, and the median time from initial outpatient consultation to orchidectomy was 9 days. DISCUSSION AND CONCLUSIONS: A patient-centric pathway ensures that the uptake of semen cryopreservation remains high particularly for those men within the common age for paternity. It also identifies men who may benefit from microdissection oncoTESE for complex cases such as tumours in solitary testicles, bilateral tumours or an atrophic contralateral testicle as well as those diagnosed with de novo azoospermia. The additional time taken for semen cryopreservation to be performed did not significantly delay orchidectomy or influence the decisions for adjuvant treatment.

Phase Ib Clinical Trial of IGV-001 for Patients with Newly Diagnosed Glioblastoma.

PURPOSE: Despite standard of care (SOC) established by Stupp, glioblastoma remains a uniformly poor prognosis. We evaluated IGV-001, which combines autologous glioblastoma tumor cells and an antisense oligonucleotide against IGF type 1 receptor (IMV-001), in newly diagnosed glioblastoma. PATIENTS AND METHODS: This open-label protocol was approved by the Institutional Review Board at Thomas Jefferson University. Tumor cells collected during resection were treated ex vivo with IMV-001, encapsulated in biodiffusion chambers with additional IMV-001, irradiated, then implanted in abdominal acceptor sites. Patients were randomized to four exposure levels, and SOC was initiated 4-6 weeks later. On the basis of clinical improvements, randomization was halted after patient 23, and subsequent patients received only the highest exposure. Safety and tumor progression were primary and secondary objectives, respectively. Time-to-event outcomes were compared with the SOC arms of published studies. RESULTS: Thirty-three patients were enrolled, and median follow-up was 3.1 years. Six patients had adverse events (grade ≤3) possibly related to IGV-001. Median progression-free survival (PFS) was 9.8 months in the intent-to-treat population (vs. SOC, 6.5 months; P = 0.0003). In IGV-001-treated patients who met Stupp-eligible criteria, PFS was 11.6 months overall (n = 22; P = 0.001) and 17.1 months at the highest exposure (n = 10; P = 0.0025). The greatest overall survival was observed in Stupp-eligible patients receiving the highest exposure (median, 38.2 months; P = 0.044). Stupp-eligible patients with methylated O6-methylguanine-DNA methyltransferase promoter (n = 10) demonstrated median PFS of 38.4 months (P = 0.0008). Evidence of immune activation was noted. CONCLUSIONS: IGV-001 was well tolerated, PFS compared favorably with SOC, and evidence suggested an immune-mediated mechanism (ClinicalTrials.gov: NCT02507583).

Femoroacetabular translation in female athletes and dancers assessed by dynamic hip ultrasonography.

OBJECTIVE: To compare femoroacetabular (FA) translation between dancers and athletes with hip pain and between dancers with and without hip pain. METHODS: In this cross-sectional study, 171 female athletes and dancers with hip pain underwent dynamic hip ultrasound (DHUS) of FA translation in three positions: neutral (N), neutral with contralateral hip flexion (NF), apprehension position with contralateral hip flexion (EER-F). Multivariable linear regression analysis was used to assess variation in FA translation between dancers and athletes in the presence of age, Beighton score/hypermobility, BMI, radiographic markers of acetabular dysplasia and femoral version angles. Symptomatic dancers were matched to asymptomatic dancer controls on age, height and BMI, and comparison analyses of FA translation were conducted controlling for matched propensity score and Beighton score. RESULTS: In the symptomatic cohort, dancers were younger, had higher Beighton scores and were more hypermobile than non-dancers. Dancers also showed greater NF, EER-F and max US-min US (delta) compared with non-dancers (mean 5.4 mm vs 4.4 mm, p=0.02; mean 6.3 mm vs 5.2 mm, p=0.01; 4.2 mm vs 3.6 mm, p=0.03, respectively). Symptomatic dancers showed greater NF and EER-F compared with asymptomatic dancers (mean 5.5 mm vs 2.9 mm, p<0.001; mean 6.3 mm vs 4.2 mm, p<0.001, respectively). Comparison of symptomatic dancers with and without hip dysplasia showed no difference in DHUS measurements. CONCLUSION: DHUS measurements of FA translation are greater in female dancers with hip pain relative to female non-dancer athletes with hip pain and asymptomatic female dancers.

Special Considerations for Growing Dancers.

Care of young dancers requires a unique approach during a critical time of growth and development. Young dancers' well-being depends on factors including sleep, mental health, growth-associated musculoskeletal imbalances, and nutrition. Puberty is a particularly important time for young dancers. It coincides with an increased commitment to their art form and physical/psychosocial changes. It is imperative for practitioners to understand these various factors in order to optimize young dancers' health and allow them to safely train and perform.

Predicting heart failure events in patients with coronary heart disease and impaired glucose tolerance: Insights from the Acarbose Cardiovascular Evaluation (ACE) trial.

AIMS: Heart failure is a fatal complication of type 2 diabetes but little is known about its incidence in people with impaired glucose tolerance (IGT). We used Acarbose Cardiovascular Evaluation (ACE) trial data to identify predictors of hospitalisation for heart failure (hHF) or cardiovascular (CV) death in patients with coronary heart disease (CHD) and IGT randomised to acarbose or placebo. METHODS: Independent hHF/CV death risk factors were determined using Cox proportional hazards models, with participants censored at first hHF event, CV death, or end of follow-up. RESULTS: During median 5-year follow-up, the composite outcome of hHF/CV death occurred in 393 (6.0%) participants. Significant hHF/CV death multivariate predictors were higher age and plasma creatinine, and prior heart failure (HF), myocardial infarction (MI), atrial fibrillation (AF) and stroke. Acarbose, compared with placebo, did not reduce hHF/CV death (hazard ratio [HR] 0.89, 95% CI 0.64-1.24, P = 0.48) or hHF (HR 0.90, 95% CI 0.74-1.10, P = 0.32). CONCLUSIONS: Patients with CHD and IGT at greater risk of hHF/CV death were older with higher plasma creatinine, prior HF, MI, AF or stroke. Addition of acarbose to optimised CV therapy to reduce post-prandial glucose excursions did not reduce the risk of hHF/CV death or hHF.

Theory and implementation of a novel stochastic approach to coupled cluster.

We present a detailed discussion of our novel diagrammatic coupled cluster Monte Carlo (diagCCMC) [Scott et al. J. Phys. Chem. Lett. 10, 925 (2019)]. The diagCCMC algorithm performs an imaginary-time propagation of the similarity-transformed coupled cluster Schrödinger equation. Imaginary-time updates are computed by the stochastic sampling of the coupled cluster vector function: each term is evaluated as a randomly realized diagram in the connected expansion of the similarity-transformed Hamiltonian. We highlight similarities and differences between deterministic and stochastic linked coupled cluster theory when the latter is re-expressed as a sampling of the diagrammatic expansion and discuss details of our implementation that allow for a walker-less realization of the stochastic sampling. Finally, we demonstrate that in the presence of locality, our algorithm can obtain a fixed errorbar per electron while only requiring an asymptotic computational effort that scales quartically with system size, independent of the truncation level in coupled cluster theory. The algorithm only requires an asymptotic memory cost scaling linearly, as demonstrated previously. These scaling reductions require no ad hoc modifications to the approach.

The Cal-DSH diversion guidelines.

The Cal-DSH Diversion Guidelines provide 10 general guidelines that jurisdictions should consider when developing diversion programs for individuals with a serious mental illness (SMI) who become involved in the criminal justice system. Screening for SMI in a jail setting is reviewed. In addition, important treatment interventions for SMI and substance use disorders are highlighted with the need to address criminogenic risk factors highlighted.
