Anticipatory, Relief-Oriented and Permissive Beliefs in Patients with Suicidal Behaviors: An Exploratory Case-Control Study

Abstract Objective The objective is to propose a specific understanding of decision-making in suicidal behavior by using a psychometric instrument, namely the Suicidal Ambivalence Scale (SAS). The SAS, initially used in addictive disorders, allows to distinguish 3 types of thoughts: first anticipatory beliefs [A] (positive expectations regarding behavior); second relief-oriented beliefs [R] (aim to reduce the feeling of suffering) and finally, permissive beliefs [P] (authorize the passage to the act). In addictions disorders, these thoughts favor craving and the act of consumption. We make the hypothesis that the processes of suicidal thoughts function similarly to thought processes in addiction and that all thoughts [A, S and P] are significantly more present in suicidal patients. Methods 120 suicidal crisis patients and 161 healthy controls were compared on clinical dimensions (levels of depression, hopelessness). Anticipatory, relief-oriented and permissive beliefs were evaluated with the suicidal ambivalence scale. Results Patients have statistically more of beliefs in favor of suicidal behavior to compared healthy controls (t = 2.375, p = 0.019, d = 0.57), more particularly, anticipatory and permissive beliefs. Conversely, patients have statistically less of protective thoughts against the suicidal behavior to compared healthy controls (t = 2.195, p = 0.03, d = 0.499). Conclusion This study showed the role of anticipatory, relief-oriented and permissive beliefs in the suicidal crisis and the need to create a simple and easy to use clinical tool for more accurate assessments of beliefs in patients with the suicidal crisis.
Brain Stiffness Relates to Dynamic Balance Reactions in Children With Cerebral Palsy

Cerebral palsy is a neurodevelopmental movement disorder that affects coordination and balance. Therapeutic treatments for balance deficiencies in this population primarily focus on the musculoskeletal system, whereas the neural basis of balance impairment is often overlooked. Magnetic resonance elastography (MRE) is an emerging technique that has the ability to sensitively assess microstructural brain health through in vivo measurements of neural tissue stiffness. Using magnetic resonance elastography, we have previously measured significantly softer grey matter in children with cerebral palsy as compared with typically developing children. To further allow magnetic resonance elastography to be a clinically useful tool in rehabilitation, we aim to understand how brain stiffness in children with cerebral palsy is related to dynamic balance reaction performance as measured through anterior and posterior single-stepping thresholds, defined as the standing perturbation magnitudes that elicit anterior or posterior recovery steps. We found that global brain stiffness is significantly correlated with posterior stepping thresholds (P = .024) such that higher brain stiffness was related to better balance recovery. We further identified specific regions of the brain where stiffness was correlated with stepping thresholds, including the precentral and postcentral gyri, the precuneus and cuneus, and the superior temporal gyrus. Identifying brain regions affected in cerebral palsy and related to balance impairment can help inform rehabilitation strategies targeting neuroplasticity to improve motor function.
The interplay between childhood trauma, cognitive biases, and cannabis use on the risk of psychosis in nonclinical young adults in Poland

Abstract Background. Childhood traumatic events are risk factors for psychotic-like experiences (PLEs). However, the mechanisms explaining how trauma may contribute to the development of PLEs are not fully understood. In our study, we investigated whether cannabis use and cognitive biases mediate the relationship between early trauma and PLEs. Methods. A total sample of 6,772 young adults (age 26.6 ± 4.7, 2,181 male and 3,433 female) was recruited from the general population to participate in an online survey. We excluded 1,158 individuals due to a self-reported lifetime diagnosis of any mental disorder. The online survey included selected items from the following questionnaires: Traumatic Experience Checklist (TEC, 3 items), Childhood Experience of Care and Abuse Questionnaire (CECA.Q, 3 items), Cannabis Problems Questionnaire (CPQ, 10 items), Davos Assessment of Cognitive Biases Scale (DACOBS-18, 9 items), and Prodromal Questionnaire-16 (PQ-16). Mediation analyses were performed with respect to different categories of traumatic experiences (emotional, physical and sexual abuse as well as emotional neglect). Results. Our results showed significant associations of any time of childhood trauma with higher scores of cannabis use (CPQ), cognitive biases (DACOBS), and PLEs (PQ-16) (p < 0.001). We found a direct effect of childhood trauma on PLEs as well as significant indirect effect mediated through cannabis use and cognitive biases. All models tested for the effects of specific childhood adversities revealed similar results. The percentage of variance in PQ-16 scores explained by serial mediation models varied between 32.8 and 34.2% depending on childhood trauma category. Conclusion. Cannabis use and cognitive biases play an important mediating role in the relationship between childhood traumatic events and the development of PLEs in a nonclinical young adult population.
Subarachnoid Extension Predicts Lobar Intracerebral Hemorrhage Expansion

Background and Purpose— We investigated whether subarachnoid extension (SAHE) of intracerebral hemorrhage (ICH) is associated with hematoma expansion (HE). Methods— Retrospective analysis of patients with primary spontaneous ICH admitted at 3 academic hospitals in Italy. The study population was divided into a development and a replication cohort. SAHE was rated on baseline noncontrast computed tomography by investigators blinded to clinical data. The main outcome of interest was HE, defined as ICH growth >33% mL and/or >6 mL. Predictors of HE were explored with multivariable logistic regression stratified by ICH location (lobar versus nonlobar). Results— A total of 360 and 192 patients were included in the development and replication cohort, respectively. SAHE was identified with good interrater reliability (K=0.82), and its frequency was 27.8% in the development and 24.5% in the replication cohort. In univariate analysis, HE was more common in patients with SAHE (52.0% versus 27.3%; P<0.001). When controlling for confounders in logistic regression, SAHE was an independent predictor of lobar HE (odds ratio, 6.00 [95% CI, 2.16–16.64]; P=0.001) whereas there was no association with HE in nonlobar ICH (odds ratio, 0.55 [95% CI, 0.17–1.84]; P=0.334). The increased risk of HE in lobar ICH with SAHE was confirmed in the replication cohort (odds ratio, 3.46 [95% CI, 1.07–11.20]; P=0.038). Conclusions— SAHE predicts HE in lobar ICH. This may improve the stratification of HE risk in clinical practice or future trials targeting HE. Further research is needed to confirm our findings and characterize the underlying biological mechanisms.
A Multi-Level Analyses of Charges and Cost of Fall-Related Hospitalizations Among Older Adults: Individual, Hospital, and Geospatial Variation

ABSTRACT The growing population of older adults has attracted concern from policymakers due in part to the fact that they are at higher risk of costly and potentially injurious falls. Responding to this concern, this study investigated fall-related hospitalizations among those aged 65 and older. Hospitalizations rose from 49,299 to 58,931, with charges and costs (estimated based on charges) increasing from $2.5 billion to $3.6 billion and under $900 million to over $1.1 billion, respectively. The intraclass correlation coefficients from linear mixed-effect models (with charges and costs serving as dependent variables) indicated differences in hospitals accounted for nearly half or more of medical cost variation among older adults suffering a fall-related hospitalization. Nonmetropolitan residence, being aged 65–69 (versus older), and higher risk-of-mortality on admission indicated higher costs. Identifying trends of fall-related hospitalizations over time allows for key stakeholders to not only track the burden of falls among older adults but to also use this information to attract funding for fall prevention strategies from policy makers at various levels (e.g., locally, at the state). Further, identifying characteristics of individuals (e.g., age, race, sex) and places (e.g., rural areas) that carry a higher relative cost can serve to inform the targeted allocation of finite resources including local, state, or federal funding, but also existing evidence-based practices such as community and clinical interventions.
Enhanced antitumour efficacy of functionalized doxorubicin plus schisandrin B co-delivery liposomes via inhibiting epithelial-mesenchymal transition

Abstract Non-small cell lung cancer (NSCLC) is a malignant cancer characterized by easy invasion, metastasis and poor prognosis, so that conventional chemotherapy cannot inhibit its invasion and metastasis. Doxorubicin (DOX), as a broad-spectrum antitumour drug, cannot be widely used in clinic because of its poor targeting, short half-life, strong toxicity and side effects. Therefore, the aim of our study is to construct a kind of PFV modified DOX plus schisandrin B liposomes to solve the above problems, and to explore its potential mechanism of inhibiting NSCLC invasion and metastasis. The antitumour efficiency of the targeting liposomes was carried out by cytotoxicity, heating ablation, wound healing, transwell, vasculogenic mimicry channels formation and metastasis-related protein tests in vitro. Pharmacodynamics were evaluated by tumour inhibition rate, HE staining and TUNEL test in vivo. The enhanced anti-metastatic mechanism of the targeting liposomes was attributed to the downregulation of vimentin, vascular endothelial growth factor, matrix metalloproteinase 9 and upregulation of E-cadherin. In conclusion, the PFV modified DOX plus schisandrin B liposomes prepared in this study provided a treatment strategy with high efficiency for NSCLC.
Branched-Chain Amino Acid Catabolism Promotes Thrombosis Risk by Enhancing Tropomodulin-3 Propionylation in Platelets

Supplemental Digital Content is available in the text. Background: Branched-chain amino acids (BCAAs), essential nutrients including leucine, isoleucine, and valine, serve as a resource for energy production and the regulator of important nutrient and metabolic signals. Recent studies have suggested that dysfunction of BCAA catabolism is associated with the risk of cardiovascular disease. Platelets play an important role in cardiovascular disease, but the functions of BCAA catabolism in platelets remain unknown. Methods: The activity of human platelets from healthy subjects before and after ingestion of BCAAs was measured. Protein phosphatase 2Cm specifically dephosphorylates branched-chain α-keto acid dehydrogenase and thereby activates BCAA catabolism. Protein phosphatase 2Cm–deficient mice were used to elucidate the impacts of BCAA catabolism on platelet activation and thrombus formation. Results: We found that ingestion of BCAAs significantly promoted human platelet activity (n=5; P<0.001) and arterial thrombosis formation in mice (n=9; P<0.05). We also found that the valine catabolite α-ketoisovaleric acid and the ultimate oxidation product propionyl-coenzyme A showed the strongest promotion effects on platelet activation, suggesting that the valine/α-ketoisovaleric acid catabolic pathway plays a major role in BCAA-facilitated platelet activation. Protein phosphatase 2Cm deficiency significantly suppresses the activity of platelets in response to agonists (n=5; P<0.05). Our results also suggested that BCAA metabolic pathways may be involved in the integrin αIIbβ3–mediated bidirectional signaling pathway that regulates platelet activation. Mass spectrometry identification and immunoblotting revealed that BCAAs enhanced propionylation of tropomodulin-3 at K255 in platelets or Chinese hamster ovary cells expressing integrin αIIbβ3. The tropomodulin-3 K255A mutation abolished propionylation and attenuated the promotion effects of BCAAs on integrin-mediated cell spreading, suggesting that K255 propionylation of tropomodulin-3 is an important mechanism underlying integrin αIIbβ3–mediated BCAA-facilitated platelet activation and thrombosis formation. In addition, the increased levels of BCAAs and the expression of positive regulators of BCAA catabolism in platelets from patients with type 2 diabetes mellitus are significantly correlated with platelet hyperreactivity. Lowering dietary BCAA intake significantly reduced platelet activity in ob/ob mice (n=4; P<0.05). Conclusions: BCAA catabolism is an important regulator of platelet activation and is associated with arterial thrombosis risk. Targeting the BCAA catabolism pathway or lowering dietary BCAA intake may serve as a novel therapeutic strategy for metabolic syndrome–associated thrombophilia.
Associations of Peripheral Artery Disease With Calf Skeletal Muscle Mitochondrial DNA Heteroplasmy

Background Patients with peripheral artery disease (PAD) undergo frequent episodes of ischemia‐reperfusion in lower extremity muscles that may negatively affect mitochondrial health and are associated with impaired mobility. We hypothesized that skeletal muscle from PAD patients will show high mitochondrial DNA heteroplasmy, especially in regions more susceptible to oxidative damage, such as the displacement loop, and that the degree of heteroplasmy will be correlated with the severity of ischemia and mobility impairment. Methods and Results Mitochondrial mutations and deletions and their relative abundance were identified by targeted mitochondrial DNA sequencing in biopsy specimens of gastrocnemius muscle from 33 PAD (ankle brachial index <0.9) and 9 non‐PAD (ankle brachial index >0.9) subjects aged ≥60 years. The probability of heteroplasmy per DNA base was significantly higher for PAD subjects than non‐PAD within each region. In adjusted models, PAD was associated with higher heteroplasmy than non‐PAD (P=0.003), but the association was limited to microheteroplasmy, that is heteroplasmy found in 1% to 5% of all mitochondrial genomes (P=0.004). Heteroplasmy in the displacement loop and coding regions were significantly higher for PAD than non‐PAD subjects after adjustment for age, sex, race, and diabetes mellitus (P=0.037 and 0.004, respectively). Low mitochondrial damage, defined by both low mitochondrial DNA copy number and low microheteroplasmy, was associated with better walking performance. Conclusions People with PAD have higher “low frequency” heteroplasmy in gastrocnemius muscle compared with people without PAD. Among people with PAD, those who had evidence of least mitochondrial damage, had better walking performance than those with more mitochondrial damage.

Do Patients With Parkinson’s Disease With Freezing of Gait Respond Differently Than Those Without to Treadmill Training Augmented by Virtual Reality?

Background. People with Parkinson’s disease and freezing of gait (FOG+) have more falls, postural instability and cognitive impairment compared with FOG−. Objective. To conduct a secondary analysis of the V-TIME study, a randomized, controlled investigation showing a greater reduction of falls after virtual reality treadmill training (TT + VR) compared with usual treadmill walking (TT) in a mixed population of fallers. We addressed whether these treadmill interventions led to similar gains in FOG+ as in FOG−. Methods. A total of 77 FOG+ and 44 FOG− were assigned randomly to TT + VR or TT. Participants were assessed pre- and posttraining and at 6 months’ follow-up. Main outcome was postural stability assessed by the Mini Balance Evaluation System Test (Mini-BEST) test. Falls were documented using diaries. Other outcomes included the New Freezing of Gait Questionnaire (NFOG-Q) and the Trail Making Test (TMT-B). Results. Mini-BEST scores and the TMT-B improved in both groups after training (P = .001), irrespective of study arm and FOG subgroup. However, gains were not retained at 6 months. Both FOG+ and FOG− had a greater reduction of falls after TT + VR compared with TT (P = .008). NFOG-Q scores did not change after both training modes in the FOG+ group. Conclusions. Treadmill walking (with or without VR) improved postural instability in both FOG+ and FOG−, while controlling for disease severity differences. As found previously, TT + VR reduced falls more than TT alone, even among those with FOG. Interestingly, FOG itself was not helped by training, suggesting that although postural instability, falls and FOG are related, they may be controlled by different mechanisms.
Lipid and cardiometabolic features of T2DM patients achieving stricter LDL-C and non-HDL-C targets in accordance with ESC/EAS 2019 guidelines

Abstract Background New recommendations call for lowering LDL-C < 55 mg/dL and non-HDL-C < 85 mg/dL in very-high cardiovascular risk (VH-CVR) patients with type 2 diabetes (T2DM). This study assessed the proportion of VH-CVR diabetics currently meeting these primary and secondary lipid targets, and which therapies/phenotypes predict combined goals achievement. Methods We analysed the cardiometabolic phenotype, use of lipid-modulatind drugs (LMD), pre- and post-LMD lipids levels, and CV complications among 1196 T2DM with high (n = 221; 18%) or VH-CVR (n = 975; 82%). Among the latter, the characteristics of combined lipid goal-achievers (n = 158) were compared to those of non-achievers (n = 817), with subgroup analyses of on-statin patients (n = 732) and those with established CVD taking statins (n = 362). Presence of statin-associated muscle symptoms (SAMS) was also recorded. Results 75% of VH-CVR patients were on statins. Both LDL-C and non-HDL-C goals were achieved by 16.2% of all VH-CVR, 19.3% of on-statin VH-CVR, and 24.3% of patients with established CVD taking statins. Achieving both targets was associated with high-intensity statins, specifically rosuvastatin, [statin + ezetimibe] combination, lower baseline LDL-C, smaller LDLs, lower TG and lipoprotein(a), and reduced metabolic syndrome frequency. SAMS reporting did not differ between achievers and non-achievers. Conclusions More than 80% of patients are above targets. To bridge this gap, apart from treating more LMD-naive/refractory diabetics, one should consider for LDL-C to put most patients on high-intensity statins, more often with ezetimibe and, within statins, to switch preferably to rosuvastatin. As regards non-HDL-C, the off-target patients’ phenotype suggests that intensifying lifestyle measures against metabolic syndrome should supplement current therapies.
Repression of the Type I Interferon pathway underlies MYC & KRAS-dependent evasion of NK & B cells in Pancreatic Ductal Adenocarcinoma.

MYC is implicated in the development and progression of Pancreatic cancer, yet the precise level of MYC deregulation required to contribute to tumour development has been difficult to define. We used modestly elevated expression of human MYC, driven from the Rosa26 locus, to investigate the pancreatic phenotypes arising in mice from an approximation of MYC trisomy. We show that this level of MYC alone suffices to drive pancreatic neuroendocrine tumours, and to accelerate progression of KRAS-initiated precursor lesions to metastatic pancreatic ductal adenocarcinoma. Our phenotype exposed suppression of the Type I Interferon pathway by the combined actions of MYC and KRAS and we present evidence of repressive MYC/MIZ1 complexes binding directly to the promoters of type I Interferon regulators IRF5, IRF7, STAT1 and STAT2. De-repression of Interferon regulators allows pancreatic tumour infiltration of B and NK cells, resulting in increased survival.
Measuring Family Members’ Experiences of Integrating Chronic Illness Into Family Life: Preliminary Validity and Reliability of the Family Integration Experience Scale:Chronic Illness (FIES:CI)

Measures of family members’ experiences of integrating chronic conditions (CC) or chronic illnesses (CI) into family life are needed to optimize family care. This article reports development and psychometric testing of the Family Integration Experience Scale: Chronic Illness (FIES:CI), a measure of family member perceptions of integrating CC or CI into evolving family life. Family Systems Nursing (FSN), the Reintegration Within Families in the Context of Chronic Illness Model, and measurement theory guided the study. Participants were those (N = 328) managing a CC or CI. Concurrent validity (r = +.629; p < .001) and discriminant validity, F(1, 155) = 7.09; p < . 05, were demonstrated. Exploratory factor analysis revealed a two-dimensional model explaining 63.8% variance. Scale internal reliability was α = . 70 and . 785, and factor reliabilities were α = . 798 (Factor 1) and α = . 847 (Factor 2). Test–retest item and subscale correlations, while accounting for intra-family correlation, were acceptable. The FIES:CI contributes a valuable new measure of family integration in the context of CC or CI with preliminary validity and reliability as tested in these samples.
Effects of HIV status on non-metastatic cervical cancer progression among patients in Lusaka, Zambia

Introduction Sub-Saharan Africa has the highest global incidence of cervical cancer. Cervical cancer is the most common cause of cancer morbidity and mortality among women in Zambia. HIV increases the risk for cervical cancer and with a national Zambian adult HIV prevalence of 16%, it is important to investigate the impact of HIV on the progression of cervical cancer. We measured differences in cervical cancer progression between HIV-positive and HIV-negative patients in Zambia. Methods This study included 577 stage I and II cervical cancer patients seen between January 2008 and December 2012 at the Cancer Diseases Hospital in Lusaka, Zambia. The inclusion criteria for records during the study period included known HIV status and FIGO stage I and II cervical cancer at initial date of registration in the Cancer Diseases Hospital. Medical records were abstracted for clinical and epidemiological data. Cancer databases were linked to the national HIV database to assess HIV status among cervical cancer patients. Logistic regression examined the association between HIV and progression, which was defined as metastatic or residual tumor after 3 months of initial treatment. Results A total of 2451 cervical cancer cases were identified, and after exclusion criteria were performed the final analysis population totaled 537 patients with stage I and II cervical cancer with known HIV status (224 HIV-positive and 313 HIV-negative). HIV-positive women were, on average, 10 years younger than HIV-negative women who had a median age of 42, ranging between 25 and 72. A total of 416 (77.5%) patients received external beam radiation, and only 249 (46.4%) patients received the recommended treatment of chemotherapy, external beam radiation, and brachytherapy. Most patients were stage II (85.7%) and had squamous cell carcinoma (74.7%). HIV-positive patients were more likely to receive lower doses of external beam radiation than HIV-negative patients (47% vs 37%; P<0.05, respectively). The median total dose of external beam radiation for HIV-positive and HIV-negative patients was 46 Gy and 50 Gy, respectively. HIV positivity did not lead to tumor progression (25.4% in HIV-positive vs 23.9% in HIV-negative, OR 1.04, 95% CI [0.57, 1.92]). However, among a subset of HIV-positive patients, longer duration of infection was associated with lower odds of progression. Conclusion There was no significant impact on non-metastatic cervical cancer progression by HIV status among patients in Lusaka, Zambia. The high prevalence of HIV among cervical cancer patients suggest that HIV-positive patients should be a primary target group for HPV vaccinations, screening, and early detection.
