Pyruvate metabolism dictates fibroblast sensitivity to GLS1 inhibition during fibrogenesis.

Fibrosis is a chronic disease characterized by excessive extracellular matrix production, which leads to disruption of organ function. Fibroblasts are key effector cells of this process, responding chiefly to the pleiotropic cytokine transforming growth factor-β1 (TGF-β1), which promotes fibroblast to myofibroblast differentiation. We found that extracellular nutrient availability profoundly influenced the TGF-β1 transcriptome of primary human lung fibroblasts and that biosynthesis of amino acids emerged as a top enriched TGF-β1 transcriptional module.

Single-cell analysis of bronchoalveolar cells in inflammatory and fibrotic post-COVID lung disease.

Background: Persistent radiological lung abnormalities are evident in many survivors of acute coronavirus disease 2019 (COVID-19). Consolidation and ground glass opacities are interpreted to indicate subacute inflammation whereas reticulation is thought to reflect fibrosis. We sought to identify differences at molecular and cellular level, in the local immunopathology of post-COVID inflammation and fibrosis.

The effectiveness of out-of-hours palliative care telephone advice lines: A rapid systematic review.

Background: People with palliative care needs and their carers often rely on out-of-hours services to remain at home. Policymakers have recommended implementing telephone advice lines to ensure 24/7 access to support. However, the impact of these services on patient and carer outcomes, as well as the health care system, remains poorly understood.

Age-specific nasal epithelial responses to SARS-CoV-2 infection.

Children infected with SARS-CoV-2 rarely progress to respiratory failure. However, the risk of mortality in infected people over 85 years of age remains high. Here we investigate differences in the cellular landscape and function of paediatric (<12 years), adult (30-50 years) and older adult (>70 years) ex vivo cultured nasal epithelial cells in response to infection with SARS-CoV-2.

Telephone advice lines for adults with advanced illness and their family carers: a qualitative analysis and novel practical framework.

Background: Telephone advice lines have been recommended internationally to support around-the-clock care for people living at home with advanced illness. While they undoubtedly support care, there is little evidence about what elements are needed for success. A national picture is needed to understand, improve and standardise service delivery/care.

Elevated ferritin, mediated by IL-18 is associated with systemic inflammation and mortality in acute respiratory distress syndrome (ARDS).

Background: Inflammatory subphenotypes have been identified in acute respiratory distress syndrome (ARDS). Hyperferritinaemia in sepsis is associated with hyperinflammation, worse clinical outcomes, and may predict benefit with immunomodulation. Our aim was to determine if raised ferritin identified a subphenotype in patients with ARDS.

Pulmonary fibrosis: Emerging diagnostic and therapeutic strategies.

Fibrosis is the concluding pathological outcome and major cause of morbidity and mortality in a number of common chronic inflammatory, immune-mediated and metabolic diseases. The progressive deposition of a collagen-rich extracellular matrix (ECM) represents the cornerstone of the fibrotic response and culminates in organ failure and premature death. Idiopathic pulmonary fibrosis (IPF) represents the most rapidly progressive and lethal of all fibrotic diseases with a dismal median survival of 3.

Nutrition-based implications and therapeutics in the development and recovery of bronchopulmonary dysplasia.

Premature births account for over 10% of live births worldwide. Bronchopulmonary dysplasia (BPD) represents a severe sequela in neonates born very prematurely and remains the most common chronic neonatal lung disease, often leading to serious adverse consequences in adulthood. Nutrition plays a crucial role in lung development and repair.

A preparative small-molecule mimic of liver CYP450 enzymes in the aliphatic C-H oxidation of carbocyclic -heterocycles.

An emerging trend in small-molecule pharmaceuticals, generally composed of nitrogen heterocycles (-heterocycles), is the incorporation of aliphatic fragments. Derivatization of the aliphatic fragments to improve drug properties or identify metabolites often requires lengthy de novo syntheses. Cytochrome P450 (CYP450) enzymes are capable of direct site- and chemo-selective oxidation of a broad range of substrates but are not preparative.

Assessing the Effectiveness of the Respecting the Circle of Life Project on Condom and Contraception Self-efficacy Among American Indian Youth.

Respecting the Circle of Life (RCL) is a teen pregnancy prevention program that was evaluated for effectiveness on sexual health risk behaviors through a two-arm randomized control trial (RCT) with American Indian (AI) youth ages 11-19. The objective of this study is to investigate the effects of RCL compared to a control group on items of condom and contraception self-efficacy. Linear regression analysis was used to compare differences in each item that included condom and contraception self-efficacy scales among the intervention and control participants at baseline, 3 and 9 months post intervention.

Implementation Fidelity and Theory-Informed Dose Effects of a Teen Pregnancy Prevention Program for Native American Youth.

In 2019, Native youth had the highest rate of teen pregnancy of all racial/ethnic groups. "Respecting the Circle of Life" (RCL) is one of the first evidence-based teen pregnancy prevention programs for Native teens and there is interest in replicating the program across tribal communities. To inform replication, it is important to consider process data including quality, fidelity, and dosage as these may all moderate impact of the program.

Inclusion of palliative and end of life care in health strategies aimed at integrated care: a documentary analysis [version 2; peer review: 2 approved].

Background: In England, Integrated Care Systems have been established to improve integration of care, as part of the NHS Long Term Plan. For people near the end of life, palliative care can improve integration of care. We aimed to understand whether and how palliative and end of life care was included in Integrated Care System strategies, and to consider priorities for strengthening this.

Adaptation and multicentre validation of a patient-centred outcome scale for people severely ill with COVID (IPOS-COV).

Background: Patient-centred measures to capture symptoms and concerns have rarely been reported in severe COVID. We adapted and tested the measurement properties of the proxy version of the Integrated Palliative care Outcome Scale-IPOS-COV for severe COVID using psychometric approach.

Methods: We consulted experts and followed consensus-based standards for the selection of health status measurement instruments and United States Food and Drug Administration guidance for adaptation and analysis.

Translation and cross-cultural adaptation of the Integrated Palliative Care Outcome Scale in Hindi: Toward capturing palliative needs and concerns in Hindi speaking patients.

Background: Culturally relevant patient-centered outcomes tools are needed to identify the needs of patients and to assess their palliative care concerns.

Aim: To translate and culturally adapt the Integrated Palliative Care Outcome Scale (IPOS) into Hindi.

Design: The study applied a standardized methodology entailing six phases for translation and content validation: equivalence setting through a three-step process; forward translation; blind backward translation; expert review by a panel of the POS team; cognitive de-briefing with patients; and proof-reading of the final tool.

Residual Lung Abnormalities after COVID-19 Hospitalization: Interim Analysis of the UKILD Post-COVID-19 Study.

Shared symptoms and genetic architecture between coronavirus disease (COVID-19) and lung fibrosis suggest severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may lead to progressive lung damage. The UK Interstitial Lung Disease Consortium (UKILD) post-COVID-19 study interim analysis was planned to estimate the prevalence of residual lung abnormalities in people hospitalized with COVID-19 on the basis of risk strata. The PHOSP-COVID-19 (Post-Hospitalization COVID-19) study was used to capture routine and research follow-up within 240 days from discharge.

Symptom management in people dying with COVID-19: multinational observational study.

Objectives: To describe multinational prescribing practices by palliative care services for symptom management in patients dying with COVID-19 and the perceived effectiveness of medicines.

Methods: We surveyed specialist palliative care services, contacted via relevant organisations between April and July 2020. Descriptive statistics for categorical variables were expressed as counts and percentages.

Charitably funded hospices and the challenges associated with the COVID-19 pandemic: a mixed-methods study (CovPall).

Background: Independent charitably funded hospices have been an important element of the UK healthcare response to the COVID-19 pandemic. Hospices usually have different funding streams, procurement processes, and governance arrangements compared to NHS provision, which may affect their experiences during the COVID-19 pandemic. The aim of this study is to understand the challenges faced by charitably funded hospices during the COVID-19 pandemic.

Predictors of STD Screening From the Indigenist Stress-Coping Model Among Native Adults With Binge Substance Use.

Objective: The American Indian/Alaska Native (AI/AN) population in the U.S. is thriving in spite of settler colonialist efforts of erasure.
