Cognitive performance in patients with neuromyelitis optica: clinical and imaging characteristics

This study aimed to identify the prevalence, clinical and radiographic characteristics, and risk factors for cognitive dysfunction in patients with Neuromyelitis optica spectrum disorder (NMOSD). Eighty-three participants who were diagnosed with NMOSD were recruited. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) and Frontal Assessment Battery (FAB). The mean age of the patients was 47.78 ± 13.14 years, with an average of 12.05 ± 4.62 years of formal education. The majority (54%) exhibited cognitive impairment, defined by a MoCA score < 25 (mean: 22.96 ± 3.82). Disease severity (evaluated by the Expanded Disability Status Scale) and lower formal education levels were associated with cognitive impairment (p = 0.011 and < 0.001, respectively). The annualized relapse rate, disease duration, and AQP4 antibody status were not associated with cognitive impairment. Interestingly, informant-reported cognitive decline was associated with poorer cognitive performance (p = 0.027). Radiographic findings of lesion location and severity were associated with MoCA-assessed cognitive performance, particularly for lesions in the right parietal lobes (p = 0.023). Hippocampal atrophy was negatively correlated with FAB scores. In conclusion, approximately half of the Thai patients with NMOSD exhibited cognitive impairment, which was associated with age, formal education level, disease severity, relative perception, and specific radiological findings. Further studies incorporating comprehensive neuropsychological tests and subjective cognitive complaints are warranted.

Sleep and circadian disruption in bipolar disorders: From psychopathology to digital phenotyping in clinical practice.

Sleep and biological rhythms are integral to mood regulation across the lifespan, particularly in bipolar disorder (BD), where alterations in sleep phase, structure, and duration occur in all mood states. These disruptions are linked to poorer quality of life, heightened suicide risk, impaired cognitive function, and increased relapse rates. This review highlights the pathophysiology of sleep disturbances in BD and aims to consolidate understanding and clinical applications of these phenomena. It also summarizes the evolution of sleep and biological rhythms assessment methods, including ecological momentary assessment (EMA) and digital phenotyping. It underscores the importance of recognizing circadian rhythm involvement in mood regulation, suggesting potential therapeutic targets. Future research directions include elucidating circadian clock gene mechanisms, understanding environmental impacts on circadian rhythms, and investigating the bidirectional relationship between sleep disturbances and mood regulation in BD. Standardizing assessment methods and addressing privacy concerns related to EMA technology and digital phenotyping are essential for advancing research. Collaborative efforts are crucial for enhancing clinical applicability and understanding the broader implications of biological rhythms in BD diagnosis and treatment. Overall, recognizing the significance of sleep and biological rhythms in BD offers promise for improved outcomes through targeted interventions and a deeper understanding of the disorder's underlying mechanisms.

Protocol for systematic review and meta-analysis on the efficacy and safety of acupuncture for residual low back pain after percutaneous kyphoplasty in patients with osteoporotic vertebral compression fracture

IntroductionOsteoporotic vertebral compression fracture (OVCF) is a common complication in elderly patients with osteoporosis. Despite undergoing percutaneous kyphoplasty (PKP) treatment, a significant percentage of OVCF patients (1.8% to 31.9%) continue...

Meta-analysis of the effectiveness of early endoscopic treatment of Acute biliary pancreatitis based on lightweight deep learning model

BackgroundAcute biliary pancreatitis (ABP) is a clinical common acute abdomen. After the first pancreatitis, relapse rate is high, which seriously affects human life and health and causes great economic burdens to family and society. According to a great many research findings, endoscopic retrograde cholangiopancreatography (ERCP) is an effective treatment method. However, whether ERCP should be performed in early stage of ABP is still controversial in clinical practice.MethodsRelated articles were retrieved from Pubmed, Web of Science core library, Nature, Science Direct, and other databases published from January 2000 until now. The keywords included early ERCP, delayed ERCP, ABP, laparoscopy, and cholecystectomy, all which were connected by “or” and “and”. The language of articles was not restricted during the retrieval and Review Manager5.3 was employed to perform meta-analysis of experimental data. Finally, a total of 8 eligible articles were selected, including 8,801 patients.ResultsThe results of the meta-analysis demonstrated that no remarkable differences were detected in the incidence of complications, mortality, and operation time between patients undergoing ERCP in early stage and those receiving delayed ERCP. However, the hospitalization time of patients in experimental group was notably shorter than that among patients in control group.ConclusinsEarly ERCP treatment is as safe as late ERCP treatment for biliary pancreatitis, and can significantly shorten the hospital stay. Hence, the therapy was worthy of clinical promotion. The research findings provided reference and basis for clinical treatment of relevant diseases.

Kinases Inhibitors as New Therapeutic Opportunities in Cutaneous T-Cell Lymphoma

Cutaneous T-cell lymphomas (CTCLs) are a heterogeneous group of T-cell lymphomas characterised by high relapse rates and no curative treatments unless the allogeneic stem cell transplantation. The main complication in the management of this kind of malignancy is the variability that characterises the genetic and clinical features among the CTCL subtypes. JAK/STAT, MAPK/ERK, PI3K/Akt, and NF-kB are those signalling pathways that are found altered in CTCL and that are responsible for promoting both T-cell malignancy and the pro-tumorigenic microenvironment. Thus, targeting key players of these pathways can be an advantageous therapeutic option for CTCL. In this review, we aim to summarise the different approaches that precisely inhibit the kinases of each cited signalling. JAK inhibitors seem to be the most promising kinase inhibitors for CTCL. However, adverse events have been reported especially in patients with immunosuppression or an underlying autoimmune disease. More studies are needed, especially clinical trials, to investigate the benefits of these drugs for the treatment of cutaneous T-cell lymphomas.

Association between low incidence of TP53 mutations and reduced early relapse rates in Uygur DLBCL.

Diffuse large B-cell lymphoma (DLBCL) demonstrates significant heterogeneity, investigations into the distinctions in clinical and molecular characteristics between Chinese Uygur and Han DLBCL patients remain unexplored. We retrospectively reviewed 279 DLBCL patients (105 Uygur and 174 Han patients), of which 155 patients underwent genetic profiling by NGS. Compared with Han patient, Uygur patients have better clinical prognostic indicators, including a higher proportion of patients with 0-1 extranodal involvement and I/II Ann Arbor staging. Consistently, Uygur patients were significantly associated with lower risk of relapse (P = 0.06), with a one-year relapse rate of 5% vs 17% and two-year relapse rate of 19% vs 36% compared to Han patients. At the molecular level, TP53 (21.3%) was among the top frequently altered gene in the cohort. Notably, the Uygur patients exhibited a significantly lower frequency of TP53 alterations and higher frequency of ASXL3 alterations. Logistic regression analysis showed that the lowered frequency of TP53 and enrichment of ASXL3 in the Uygur patients were independent of other factors. However, only patients with TP53 mutations had higher relapse rate than those with wild type TP53 (one-year, 20% vs 10%; two-year, 51% vs 21%). Our findings highlight the notable contribution of a low TP53 mutation frequency in Uygur patients as a pivotal factor associated with the favorable prognosis of this population.

Pharmacogenetics of Toxicities Related to Endocrine Treatment in Breast Cancer: A Systematic Review and Meta-analysis.

Endocrine therapy is the standard treatment for hormone receptor-positive (HR+) breast cancer (BC). Yet, it is accompanied by treatment-related toxicities, leading to poor treatment adherence, high relapse, and low rates of survival. While pharmacogenomic variants have the potential to guide personalized treatment, their predictive value is inconsistent across published studies. To systematically assess the literature's current landscape of pharmacogenomics of endocrine therapy-related adverse drug effects, systematic searches in MEDLINE, Embase, Cochrane CENTRAL, Google Scholar and PharmGKB databases were conducted. We identified 87 articles. Substantial heterogeneity and variability in pharmacogenomic effects were evident across studies, with many using data from the same cohorts and predominantly focusing on the Caucasian population and postmenopausal women. Meta-analyses revealed Factor V Leiden mutation as a predictor of thromboembolic events in tamoxifen-treated women (p<0.0001). Meta-analyses also found that rs7984870 and rs2234693 were associated with musculoskeletal toxicities in postmenopausal women receiving aromatase inhibitors (p<0.0001 and p<0.0001, respectively). Overall, the current body of evidence regarding the potential role of pharmacogenomics in endocrine therapy-related toxicity in BC remains largely inconclusive. Key concerns include the heterogeneity in toxicity definitions, lack of consideration for genotype-treatment interactions, and the failure to account for multiple testing. The review underscores the necessity for larger and well-designed studies, particularly with the inclusion of premenopausal women and non-Caucasian populations.

Self-control as mediator and social support as moderator in stress-relapse dynamics of substance dependency

Substance Use Disorders (SUDs) present a significant challenge to global public health, with prolonged drug use not only impairing individual health but also hindering social development. Despite various interventions aimed at addressing drug abuse and dependence, a high relapse rate remains a prominent issue. In light of this, this study aims to explore the impact of perceived stress on the relapse of individuals with SUDs, as well as the mediating role of self-control and the moderating role of social support, in hopes of providing new perspectives for interventions to reduce the risk of relapse among individuals with SUDs. By utilizing a convenience sampling method, 420 male individuals with SUDs were recruited from detoxification centers in Guangxi, China. They completed questionnaires on perceived stress, self-control, social support, and tendencies towards relapse. A total of 401 valid datasets were obtained and analyzed using the SPSS Process plugin to conduct a moderated mediation model analysis. Results: (1) Perceived stress had a positive impact on the relapse of individuals with SUDs, (2) Self-control played a partial mediating role between perceived stress and the relapse, (3) The direct effect of perceived stress on the relapse and its first half of the indirect effect were moderated by social support. The research emphasize the critical importance of learning stress management strategies, enhancing self-control, and receiving comprehensive social support in the prevention and treatment of substance dependence. By strengthening self-control and social support as both internal and external resources, the likelihood of relapse among individuals with SUDs can be reduced, contributing to more effective and comprehensive drug rehabilitation strategies.

Comparative efficacy of subcutaneous versus intravenous natalizumab on annualized relapse rate: A post-hoc analysis of the REFINE study

BackgroundThe non-inferiority of the efficacy of subcutaneous (SC) vs intravenous (IV) administration of natalizumab (NTZ) once every 4 weeks in relapsing-remitting multiple sclerosis (RRMS) was recently demonstrated on the primary outcome of the REFINE study, i.e. MRI “combined unique active lesions number” (CUAL). To provide further evidence on the comparative efficacy of the two NTZ formulations, the effect of NTZ-SC vs NTZ-IV on annualized relapse rate (ARR) was investigated re-analysing the REFINE dataset. MethodsPost-hoc analysis of the REFINE study dataset aimed at exploring the non-inferiority of the efficacy of NTZ-SC vs NTZ-IV on ARR, i.e. the main secondary outcome of the REFINE study. Robustness of the non-inferiority analysis on CUAL with respect to the presence of cases from the SC arm who received a rescue treatment, including NTZ-IV, was also assessed by sensitivity analyses. Three non-inferiority margins were selected, corresponding to 25 %, 33 %, and 50 % fractions of the effect size of NTZ-IV vs placebo observed in the AFFIRM study on ARR (i.e. 0.125, 0.170, and 0.250). ResultsNinety-nine RRMS patients were included. The mean difference in the effect of NTZ-SC vs NTZ-IV on ARR was close to 0. The lower bound of the 95 % confidence interval (worst case scenario) was –0.119, corresponding to 25 % (p = 0.025) of the effect of NTZ-IV vs placebo on ARR. Sensitivity analyses confirmed the results of the primary non-inferiority analysis on the outcome CUAL. ConclusionsNTZ-SC resulted not inferior to NTZ-IV on ARR for all the non-inferiority margins. The non-inferiority analysis of the efficacy of NTZ-SC vs NTZ-IV on CUAL was demonstrated to be robust with respect to rescued patients.

Pearls & Oy-sters: Optic Neuritis as First Demyelinating Event During Pregnancy in 2 Young Hispanic Women: MS vs MOGAD.

Optic neuritis (ON) can present as the first demyelinating attack in both multiple sclerosis (MS) and myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD), which may require different treatment depending on the final diagnosis. We present 2 young Hispanic women who presented with ON during pregnancy, one of whom was diagnosed with MS and the other with MOGAD. We describe key clinical features to help differentiate between MS and MOGAD including ON features, brain and spinal MRI, CSF profiles, and serum MOG and aquaporin-4 (AQP-4) antibodies, which all can help guide clinicians to an ultimate diagnosis. Pregnancy is usually considered an immunotolerant state because complex immunologic shifts arising to support tolerance of the developing fetus seem to decrease the risk of relapses. However, relapses may still occur during pregnancy, and relapse rates increase immediately postpartum. Our cases raise the possibility that young Hispanic patients may face increased risk of demyelinating disease activity even during the relatively immunotolerant state of pregnancy. A high index of suspicion for demyelinating disease should be maintained to accelerate diagnosis and prevent disability.

Clinical Efficacy and Safety of CD7-Targeted CAR T Cell Therapy for T-cell Malignancies: A Systematic Review and Meta-analysis.

Although T-cell malignancies are relatively less prevalent compared to B-cell malignancies, they are highly malignant, and patients usually have poor prognoses. Employing CD7-targeted chimeric antigen receptor (CAR) T cell therapy as a novel immunotherapy to treat malignant T cells faces numerous challenges and is in its early phase. To evaluate this possibility, we aimed to review and meta-analyze the related clinical trials systematically. On October 9, 2023, the online databases of PubMed, Scopus, Embase, and Web of Science were systematically searched for pertinent studies. After completing a two-step title/abstract and full-text screening process, the eligible studies were included. We observed a pooled overall response rate (ORR) of 100%. Partial response (PR), stringent and/or complete response (sCR/CR), and relapse rate were 6%, 85%, and 18%, respectively. Additionally, the pooled rate of minimal residual disease (MRD) negativity was 85%. The most common grade ≥3 adverse events were related to hematological toxicities, including neutropenia (100%), thrombocytopenia (79%), and anemia (57%). Cytokine release syndrome (CRS) was also a frequent complication with a 100% rate; however, 81% of CRS events were low grades. No grade ≥3 GVHD was reported, and the immune effector cell-associated neurotoxicity syndrome (ICANS grade ≥3) was rare (4%). CD7 is an active and safe target that shows promising results in the treatment of relapsed and/or refractory (r/r) T-cell malignancies.

Rituximab in secondary progressive multiple sclerosis: a meta-analysis.

To evaluate the efficacy of rituximab (RTX) in stabilizing disability progression in secondary progressive multiple sclerosis (SPMS). A systematic review was conducted, encompassing studies from inception to April 2023, utilizing the MEDLINE and EMBASE databases. Inclusion criteria comprised studies with a minimum of 3 SPMS patients receiving intravenous RTX in at least one infusion, with a follow-up duration of at least 6 months. Primary outcome measures included changes in Expanded Disability Status Scale (EDSS) scores. Mean differences in pre- and post-RTX EDSS scores were analyzed using a random-effects model. Meta-regression examined age at RTX initiation, pre-RTX EDSS scores, disease duration, and outcome reported time as variables. Secondary outcomes assessed changes in the annualized relapse rate (ARR). Thirteen studies, involving 604 SPMS patients, met the inclusion criteria. Following a mean follow-up of 2 years, the mean difference in EDSS scores (ΔEDSS = EDSSpre-RTX - EDSSpost-RTX) was -0.21 (95% CI -0.51 to 0.08, p = 0.16), indicating no significant variation. Multivariable meta-regression identified significant associations between EDSS score mean difference and pre-RTX EDSS scores, disease duration at RTX initiation, and outcome reported time. However, age at RTX initiation showed no significant association. Pre- and post-RTX ARR data were available for 245 out of 604 SPMS patients across seven studies, revealing a mean difference in ARR (ΔARR = ARRpre-RTX - ARRpost-RTX) of 0.74 (95% CI 0.19-1.29, p = 0.008). RTX demonstrates efficacy in reducing relapse frequency and exhibits potential in stabilizing disability progression over a 2-year follow-up, particularly among individuals with shorter disease duration.

Towards collaborative care for severe and enduring Anorexia Nervosa – a mixed-method approach

BackgroundSevere and Enduring Eating Disorders (SEED), in particular SEED-Anorexia Nervosa (SE-AN), may represent the most difficult disorder to treat in psychiatry. Furthermore, the lack of empirical research in this patient group, and, consequently the lack of guidelines, call for an urgent increase in research and discussion within this field. Meanwhile experts concur that effective care should be structured in a collaborative manner.ObjectiveTo identify the challenges in providing care to patients with SE-AN in the Dutch healthcare context, and propose a collaborative care treatment model to address these issues.MethodsA pragmatic mixed-method approach was used, structured as follows: (1) Identifying perceived barriers and treatment needs from the viewpoint of both patients and eating disorder healthcare professionals through an evaluation questionnaire; (2) Investigating current treatment practices for SEED/SE-AN via benchmarking; (3) Gaining insight into the optimal structure and content of care by interviewing network partners and experts-by-experience. Based on these findings, and drawing from literature on severe and enduring disorders, a treatment model for SE-AN was proposed and implemented.ResultsThe key challenges identified included a lack of knowledge about eating disorders among network partners, treatment ambivalence among patients and poor collaboration between professionals. The proposed model enhances self-management and collaborative relationships with healthcare providers, offers user-friendly and practical guidance, and aims at stabilization, reducing relapses, deterioration, and readmissions, thereby being cost-effective. Importantly, the model operates across levels of care (primary, secondary, tertiary).ConclusionThis study, describing a collaborative care program for SE-AN, developed and implemented in a highly specialized treatment center for eating disorders, sets the stage for further explanatory/efficacy research to build on the findings in this study, with the following aims: addressing the critical gap in care for SEED/SE-AN, improving better healthcare organization, reducing relapse rates, and lowering costs for this often overlooked patient group.

Long-term outcomes of infliximab treatment in neuro-Behcet syndrome: A single-center retrospective study.

Behcet's syndrome is a rare inflammatory disorder characterized by oral and genital ulcers, skin lesions, and uveitis. It exhibits a higher prevalence along the historic Silk Road. Neuro-Behcet syndrome (NBS) affects the central nervous system and poses significant morbidity and mortality risks. Infliximab, a TNF-alpha antagonist, has shown potential in NBS management, although the current evidence is mainly derived from case series due to the lack of randomized controlled trials. This retrospective study aimed to evaluate the disease outcomes during the first and second years following infliximab treatment in NBS patients experiencing attacks despite prior conventional immunosuppressive therapy. The study also sought to investigate the safety profile and adverse effects associated with infliximab. Fifty-three NBS patients were examined, with 22 receiving infliximab as either monotherapy or in combination with other therapies. Retrospective analysis was conducted on demographic data, clinical characteristics, and treatment responses. Treatment efficacy was measured using the Expanded Disability Status Scale (EDSS) modified for NBS. The study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist guidelines. Among the study cohort, 60.4% had parenchymal NBS, and 39.6% had nonparenchymal NBS. Treatment with infliximab resulted in remission or disease stabilization in 95% of patients after one year and 68.7% after 2years. Relapse rates were 4.5% at 1year and 18.7% at 2years, with disease progression observed in two cases. Adverse effects were primarily mild to moderate, with no reports of serious adverse events. Infliximab exhibited efficacy in achieving remission or stabilization in NBS patients, maintaining a favorable safety profile. The timing of infliximab treatment may prevent the accumulation of disability and hinder disease progression. Nonetheless, future prospective studies are necessary to confirm these findings and refine treatment strategies for this complex condition.

Bed nucleus of the stria terminalis network responses to unpredictable threat in early alcohol abstinence.

Anxiety during early alcohol abstinence, likely resulting from neural changes caused by chronic alcohol use, contributes to high relapse rates. Studies in rodents show heightened activation during early abstinence in the bed nucleus of the stria terminalis (BNST)-a neural hub for anxiety-and its extended anxiety-related corticolimbic network. Despite the clinical importance of early abstinence, few studies investigate the underlying neural mechanisms. To address this gap, we investigated brain function in early alcohol abstinence (EA = 20, 9 women) relative to controls (HC = 20, 11 women) using an unpredictable threat task shown to engage the BNST and corticolimbic brain regions involved in anxiety and alcohol use disorder (AUD). Group, anxiety, and sex were predictors used to determine whole-brain activation and BNST functional connectivity. We found widespread interactions of group × anxiety and group × anxiety × sex for both activation and BNST connectivity during unpredictable threat. In the EA group, higher anxiety was correlated with activation in the BNST, rostral anterior cingulate cortex (ACC), insula (men only), and dorsal ACC (men only). In the HC group, higher anxiety was negatively correlated with activation in the BNST, nucleus accumbens, thalamus, and insula (men only). For connectivity, anxiety was positively correlated in EA and negatively correlated in HC, between the BNST and the amygdala, ventromedial prefrontal cortex (PFC), and dorsomedial PFC; EA men showed stronger BNST-vmPFC connectivity than HC men. These novel findings provide preliminary evidence for alterations in the BNST and anxiety-related corticolimbic brain regions in early alcohol abstinence, adding to growing literature in humans supporting the BNST's role in anxiety and sex-dependent effects of chronic alcohol use.

Bupropion in Comorbid Post-Traumatic Stress Disorder and Methamphetamine Use Disorder.

Background: Post-traumatic stress disorder (PTSD) and substance use disorder (SUD) frequently occur together. Serotonergic agents are preferred medications to treat PTSD, while bupropion is reserved due to limited evidence. Ongoing studies suggest bupropion may be effective for treating methamphetamine use disorder (MUD). Investigators aimed to evaluate if bupropion would confer benefit to patients with Diagnostic and Statistical Manual of Mental Disorders, Fifth edition diagnoses for PTSD and MUD compared to traditional pharmacotherapy. Methods: This report describes four patients with comorbid PTSD and MUD who had a positive response to medication regimens containing bupropion compared to non-bupropion regimens for their trauma symptoms. Investigators were able to compare this to a control group of 41 patients receiving serotonergic agents alone. Case Report: PTSD checklist-civilian scores at time of medication initiation, site discharge, and post-discharge in the bupropion and non-bupropion group were 77, 35, and 29, compared to 51 ± 15, 52 ± 20 and 53 ± 10, respectively. Rates of relapse, average time to relapse, and hospital utilization in the bupropion vs non-bupropion group were 25.0% vs 48.8%, 107 days vs 210 ± 191 days, and 0% vs 29.3%, respectively. Discussion: Use of bupropion showed a greater reduction in PTSD symptom severity and a lower frequency of methamphetamine relapse and hospital utilization. Though missing data limited inclusion of patients in all outcomes, quantitative data suggests benefit with bupropion in comorbid PTSD and MUD. Conclusion: This case series suggests the potential for earlier initiation of bupropion treatment in those with PTSD who have comorbid MUD.

Optimizing Gastroesophageal Reflux Disease treatment: A call to shift from omeprazole.

Gastroesophageal reflux disease (GERD) is a disorder of the upper respiratory tract, which develops due to the regurgitation of acid from the stomach into the oesophagus. If left untreated, GERD may cause serious complications such as Barrett's oesophagus, oesophageal strictures, and oesophageal adenocarcinoma. According to a study published by Nirwan JS et al in 2020, individuals suffering from Gastroesophageal reflux disease globally is 1.03 billion.[1] Proton pump inhibitors (PPIs) are frequently used drugs for the treatment of GERD. Omeprazole belongs to PPIs class of drugs and it has been a drug of choice for GERD because it is affordable, easily available, and it can be taken along with other medicines. However, Proton pump inhibitors are not completely risk-free, chronic use of Proton Pump inhibitors has been associated with decreased calcium and magnesium absorption increasing the risk of osteoporosis and electrolyte disturbances respectively. It also increases the risk of community-acquired pneumonia [2] However, Esomeprazole the s-isomer of omeprazole yields much better results than omeprazole. It is more effective and safe in the treatment of GERD, not only does it decrease the symptoms of the disease rapidly ie. heartburn [4] but also it reduces the relapse of the symptoms twice that of omeprazole. Maintenance of intragastric pH &gt; 4 is an effective measure for the management of gastroesophageal reflux disease, esomeprazole has demonstrated improved acid inhibition over omeprazole with a high mean percentage of 24-hour intragastric pH &gt; 4. The healing rate for reflux esophagitis and relapse was also higher for esomeprazole than that of omeprazole.[3] According to a study, the number of individuals with GERD in the South Asia region is around 8000 per 100000 [4]. Knowing the extent of Gastroesophageal patients present in Pakistan and how rapidly this number can escalate due to poor lifestyle modifications. Omeprazole which is the most frequent drug prescribed for the treatment of GERD [5] should be discouraged and Esomeprazole being more beneficial in terms of healing time and relapse of symptoms should be promoted to prevent chronic use adverse effects of Proton pump inhibitors. Overall, such a measure will improve the quality of life of a person suffering from gastroesophageal reflux disease which otherwise may lead to more severe implications.

BMP4-Induced Suppression of Breast Cancer Metastasis Is Associated with Inhibition of Cholesterol Biosynthesis.

We reported previously that in preclinical models, BMP4 is a potent inhibitor of breast cancer metastasis and that high BMP4 protein levels predict favourable patient outcomes. Here, we analysed a breast cancer xenograft with or without enforced expression of BMP4 to gain insight into the mechanisms by which BMP4 suppresses metastasis. Transcriptomic analysis of cancer cells recovered from primary tumours and phosphoproteomic analyses of cancer cells exposed to recombinant BMP4 revealed that BMP4 inhibits cholesterol biosynthesis, with many genes in this biosynthetic pathway being downregulated by BMP4. The treatment of mice bearing low-BMP4 xenografts with a cholesterol-lowering statin partially mimicked the anti-metastatic activity of BMP4. Analysis of a cohort of primary breast cancers revealed a reduced relapse rate for patients on statin therapy if their tumours exhibited low BMP4 levels. These findings indicate that BMP4 may represent a predictive biomarker for the benefit of additional statin therapy in breast cancer patients.
