Pancreatic cancer metastasis is a leading cause of cancer-related deaths, yet very little is understood regarding the underlying biology. As a result, targeted therapies to inhibit metastasis are lacking. click here Here, we report that the parathyroid hormone-related protein (PTHrP encoded by PTHLH) is frequently amplified as part of the KRAS amplicon in patients with pancreatic cancer. PTHrP upregulation drives the growth of both primary and metastatic tumors in mice and is highly enriched in pancreatic ductal adenocarcinoma metastases. Loss of PTHrP-either genetically or pharmacologically-dramatically reduces tumor burden, eliminates metastasis, and enhances overall survival. These effects are mediated in part through a reduction in epithelial-to-mesenchymal transition, which reduces the ability of tumor cells to initiate metastatic cascade. Spp1, which encodes osteopontin, is revealed to be a downstream effector of PTHrP. click here Our results establish a new paradigm in pancreatic cancer whereby PTHrP is a driver of disease progression and emerges as a novel therapeutic vulnerability. SIGNIFICANCE Pancreatic cancer often presents with metastases, yet no strategies exist to pharmacologically inhibit this process. link2 Herein, we establish the oncogenic and prometastatic roles of PTHLH, a novel amplified gene in pancreatic ductal adenocarcinoma. We demonstrate that blocking PTHrP activity reduces primary tumor growth, prevents metastasis, and prolongs survival in mice.This article is highlighted in the In This Issue feature, p. 1601.Immune checkpoint blockade (ICB) therapy revolutionized cancer treatment, but many patients with impaired MHC-I expression remain refractory. Here, we combined FACS-based genome-wide CRISPR screens with a data-mining approach to identify drugs that can upregulate MHC-I without inducing PD-L1. CRISPR screening identified TRAF3, a suppressor of the NFκB pathway, as a negative regulator of MHC-I but not PD-L1. The Traf3-knockout gene expression signature is associated with better survival in ICB-naïve patients with cancer and better ICB response. We then screened for drugs with similar transcriptional effects as this signature and identified Second Mitochondria-derived Activator of Caspase (SMAC) mimetics. We experimentally validated that the SMAC mimetic birinapant upregulates MHC-I, sensitizes cancer cells to T cell-dependent killing, and adds to ICB efficacy. Our findings provide preclinical rationale for treating tumors expressing low MHC-I expression with SMAC mimetics to enhance sensitivity to immunotherapy. The approach used in this study can be generalized to identify other drugs that enhance immunotherapy efficacy. SIGNIFICANCE MHC-I loss or downregulation in cancer cells is a major mechanism of resistance to T cell-based immunotherapies. click here Our study reveals that birinapant may be used for patients with low baseline MHC-I to enhance ICB response. This represents promising immunotherapy opportunities given the biosafety profile of birinapant from multiple clinical trials.This article is highlighted in the In This Issue feature, p. 1307.The key differences between tumors arising in children and those in adults stem from the cellular origin of cancer at different ages, with adult cancers arising within aging cell hierarchies, as a consequence of accumulated damage and mutagenesis, in contrast to childhood tumors that are born in aberrantly developing tissues. A distinct biological property of childhood tumor cells-a block of developmental maturation-may hold the key to advancing the treatment of childhood cancer beyond cytotoxic strategies.A phase I trial evaluated the selective estrogen receptor degrader elacestrant in breast cancer.Pancreatic injury plus oncogenic Kras mutation produced cancer-associated chromatin states in vivo.Global health research should generate new knowledge to improve the health and well-being of those considered disadvantaged and marginalised. link2 This goal motivates much of the global health research being undertaken today. Yet simply funding and conducting global health research will not necessarily generate the knowledge needed to help reduce health disparities between and within countries. Global health research grants programmes and projects must be structured in a particular way to generate that type of information. But how exactly should they be designed to do so? Through a programme of ethics research starting in 2009, an ethical framework called Research for Health Justice was developed that provides guidance to global health researchers and funders on how to design research projects and grants programmes to promote global health equity. It provides guidance on, for example, what research populations and questions ought to be selected, what research capacity strengthening ought to be performed and what post-study benefits ought to be provided. This paper describes how the 'research for health justice' framework was generated and pulls together a body of work spanning the last decade to provide a comprehensive and up-to-date version of its guidance.Across the globe, the well-being of newborns is significantly influenced by the knowledge and practices of family members, yet global health policies and interventions primarily focus on strengthening health services to save newborn lives. Predominant approaches to promote newborn survival in non-western cultures across the Global South are based on a western, nuclear family model and ignore the roles of caregivers within wider family systems, whose attitudes and practices are determined by culturally prescribed strategies. In this paper, I review evidence of a neglected facet of newborn care, the role and influence of senior women or grandmothers.Based on a family systems frame, I reviewed research from numerous settings in Africa, Asia and Latin America that provides insight into family roles related to newborn care, specifically of grandmothers. I identified primarily published studies which provide evidence of grandmothers' role as culturally designated and influential newborn advisors to young mothers and direct caregivers. Research from all three continents reveals that grandmothers play similar core roles in newborn care while their culturally specific practices vary. This review supports two main conclusions. First, future newborn research should be conceptualised within a family systems framework that reflects the structure and dynamics of non-western collectivist cultures. Second, newborn interventions should aim not only to strengthen health services but also influential family caregivers, particularly grandmothers and the indigenous social support networks of which they are a part, in order to improve family-level newborn practices and save newborn lives.
Proton pump inhibitor (PPI) use has risen substantially, primarily driven by ongoing use over months to years. However, there is no consensus on how to define long-term PPI use. Our objectives were to review and compare definitions of long-term PPI use in existing literature and describe the rationale for each definition. Moreover, we aimed to suggest generally applicable definitions for research and clinical use.

The databases PubMed and Cochrane Library were searched for publications concerning long-term use of PPIs and ClinicalTrials.gov was searched for registered studies. Two reviewers independently screened the titles, abstracts, and full texts in two series and subsequently extracted data.

A total of 742 studies were identified, and 59 met the eligibility criteria. In addition, two ongoing studies were identified. The definition of long-term PPI use varied from >2 weeks to >7 years. The most common definition was ≥1 year or ≥6 months. link3 A total of 12/61 (20%) of the studies rationalised theirdies of adverse effects may require a tailored definition depending on the necessary exposure time. We recommend to always rationalise the choice of definition.Given the limited efficacy of pharmacological treatments, the use of musical intervention as a non-drug treatment for patients with Alzheimer's disease is strongly recommended. Musical interventions appear to improve the socio-emotional and cognitive functioning of these patients, and benefits increase when patients' motor skills are engaged. Our study evaluates the factors that may influence patients' socio-emotional and motor engagement during musical activities and measures their sensorimotor synchronisation (SMS) abilities. Participants were asked to tap in time to a metronomic or musical rhythm, in the presence of a musician who performed the task with them. The musician's presence was either physical (live condition) or virtual (video condition). link3 Two tempos were tested a slow tempo (inter-onset interval of 800 ms) and a fast tempo (inter-onset interval of 667 ms). link2 The results showed that patients spontaneously produced more rhythmic movements in response to the music than to the metronome. However, the consistency and accuracy of sensorimotor synchronisation was better with the metronome than with the music and was also better when the musician was present through the video rather than in person. These effects were modulated by the tempo of the auditory sequences. These results confirm the importance of the musical context and social interactions on these different performances. By simultaneously evaluating the sensorimotor synchronisation of the hands, spontaneous motor behaviours, and socio-emotional behaviours using quantitative and controlled measurements, this study validates a multimodal approach to evaluating patients' engagement in a musical task. These initial results provide promising prospects in terms of application while providing clinicians and researchers with a rigorous methodology for understanding the factors that are at the origin of the therapeutic benefits of musical activities on the behaviour and well-being of patients and their caregivers.
Cystic fibrosis (CF) is caused by mutations in the gene encoding the CF transmembrane regulator (CFTR) protein, a chloride channel located in the epithelial cell membrane. Over than 2,000CFTR mutations have been identified, which contribute to the variety of clinical phenotypes of CF. We performed a case-control study to determine p.Met470Val (M470V), p.Thr854= (T854) and p.Gln1463= (Q1463) polymorphisms frequencies in CF patients and healthy controls and to elaborate haplotype based on these SNPs.

The genotyping of M470V (exon 10), T854 (exon 14a), and Q1463 (exon 24) variants were identified using polymorphism restriction fragment length polymorphism (RFLP).

Statistical difference was noted in the genotype distribution of two markers, M470V and T854, between CF and control groups. link3 However, the Q1463 polymorphism is not identified in two studied groups. Three haplotypes were found in CF patients and controls. An exclusive association between the ancestral haplotype 1-1-2 and p.Phe508del (F508del) mutation was shown. In Tunisia, this is the first work to be interested in the analysis of M470V, T854 and Q1463 polymorphisms and haplotypes associated with the most common mutation, F508del, in the Tunisian population and worldwide.
