Socioeconomic inequalities in waiting times for breast cancer surgery.

Prompt access to cancer care is a policy priority in several OECD countries, because delayed access can exacerbate deleterious health outcomes. Access to care based on need remains a key pillar of publicly-funded health systems. This study tests for the presence of inequalities in waiting times by socioeconomic status for patients receiving breast cancer surgery (mastectomy or breast conserving surgery) in England using the Hospital Episode Statistics.

Assessing the uptake of incentivised physical health checks for people with serious mental illness: a cohort study in primary care.

Background: People with serious mental illness are more likely to experience physical illnesses. The onset of many of these illnesses can be prevented if detected early. Physical health screening for people with serious mental illness is incentivised in primary care in England through the Quality and Outcomes Framework (QOF).

Post-translational modification-centric base editor screens to assess phosphorylation site functionality in high throughput.

Signaling pathways that drive gene expression are typically depicted as having a dozen or so landmark phosphorylation and transcriptional events. In reality, thousands of dynamic post-translational modifications (PTMs) orchestrate nearly every cellular function, and we lack technologies to find causal links between these vast biochemical pathways and genetic circuits at scale. Here we describe the high-throughput, functional assessment of phosphorylation sites through the development of PTM-centric base editing coupled to phenotypic screens, directed by temporally resolved phosphoproteomics.

Single-Molecule DNA Methylation Reveals Unique Epigenetic Identity Profiles of T Helper Cells.

Both identity and plasticity of CD4 T helper (Th) cells are regulated in part by epigenetic mechanisms. However, a method that reliably and readily profiles DNA base modifications is still needed to finely study Th cell differentiation. Cytosine methylation in CpG context (5mCpG) and cytosine hydroxymethylation (5hmCpG) are DNA modifications that identify stable cell phenotypes, but their potential to characterize intermediate cell transitions has not yet been evaluated.

Proteome-wide base editor screens to assess phosphorylation site functionality in high-throughput.

Signaling pathways that drive gene expression are typically depicted as having a dozen or so landmark phosphorylation and transcriptional events. In reality, thousands of dynamic post-translational modifications (PTMs) orchestrate nearly every cellular function, and we lack technologies to find causal links between these vast biochemical pathways and genetic circuits at scale. Here, we describe "signaling-to-transcription network" mapping through the development of PTM-centric base editing coupled to phenotypic screens, directed by temporally-resolved phosphoproteomics.

Microsimulation Models on Mental Health: A Critical Review of the Literature.

Objectives: To retrieve and synthesize the literature on existing mental health-specific microsimulation models or generic microsimulation models used to examine mental health, and to critically appraise them.

Methods: All studies on microsimulation and mental health published in English in MEDLINE, Embase, PsycINFO, and EconLit between January 1, 2010, and September 30, 2022, were considered. Snowballing, Google searches, and searches on specific journal websites were also undertaken.

The preparation of visible-light-driven photocatalysts has become highly appealing for environmental remediation through simple, fast and green chemical methods. The current study reports the synthesis and characterization of graphitic carbon nitride/titanium dioxide (g-CN/TiO) heterostructures through a fast (1 h) and simple microwave-assisted approach. Different g-CN amounts mixed with TiO (15, 30 and 45 wt.

Reduced cardiovascular risk score following bilateral cataract phacoemulsification surgery: A retrospective observational cohort study.

Objective: To assess the cardiovascular risk (CV risk) change following bilateral phacoemulsification cataract surgery.

Methods: We performed a retrospective observation cohort study on 112 selected patients who underwent uncomplicated bilateral cataract surgery at Centro Hospitalar de Entre o Douro e Vouga (CHEDV) between 2018 and 2019. This patient cohort was further subdivided in 2 different groups: Good VA - no to mild visual impairment, ≤0.

Enhanced Fe-TiO Solar Photocatalysts on Porous Platforms for Water Purification.

In this study, polyethylene glycol-modified titanium dioxide (PEG-modified TiO) nanopowders were prepared using a fast solvothermal method under microwave irradiation, and without any further calcination processes. These nanopowders were further impregnated on porous polymeric platforms by drop-casting. The effect of adding iron with different molar ratios (1, 2, and 5%) of iron precursor was investigated.

Optical coherence tomography angiography in herpetic leucoma.

Background: Herpes simplex virus (HSV) keratitis remains a leading infectious cause of blindness worldwide. Although all forms of HSV keratitis are commonly recurrent, the risk is greatest in stromal keratitis, which is the most likely to result in corneal scarring, thinning, and neovascularization. Recent studies showed the ability of Optical Coherence Tomography Angiography (OCTA) to detect and study vascular abnormalities in the anterior segment, including abnormal corneal vessels.

Regulatory T cell differentiation is controlled by αKG-induced alterations in mitochondrial metabolism and lipid homeostasis.

Suppressive regulatory T cell (Treg) differentiation is controlled by diverse immunometabolic signaling pathways and intracellular metabolites. Here we show that cell-permeable α-ketoglutarate (αKG) alters the DNA methylation profile of naive CD4 T cells activated under Treg polarizing conditions, markedly attenuating FoxP3+ Treg differentiation and increasing inflammatory cytokines. Adoptive transfer of these T cells into tumor-bearing mice results in enhanced tumor infiltration, decreased FoxP3 expression, and delayed tumor growth.

Objectives: The aim of this study was to examine the incidence of coronavirus disease 2019 (COVID-19) among patients with immunomediated inflammatory diseases (IMIDs) treated with biologic or targeted synthetic disease-modifying antirheumatic drugs (bDMARDs and tsDMARDs) and to evaluate the influence of either IMIDs or related therapies on the incidence and evolution of COVID-19.

Methods: This observational, cross-sectional study was conducted from January 31, 2020, to May 15, 2020. Data of 902 patients were obtained from clinical records in hospitals, primary care units, and community pharmacies.

Targeting Glutamine Metabolism and PD-L1: A Novel Anti-tumor Pas de Deux.

In this issue of Molecular Cell, Byun et al. (2020) find that the dual targeting of glutamine metabolism and the PD-L1 checkpoint inhibitor augments anti-tumor immunity. Mechanistically, decreased glutamine availability attenuated S-glutathionylation of SERCA, resulting in an increase in cytosolic calcium, enhanced NF-κB activity, and upregulation of programmed death-ligand 1.

EUS-FNA Diagnosis with Core Biopsy of Pancreatic Metastases from Primary Breast Cancer.

Background: The pancreas as a site of metastasis of other primary tumors is a rare event. Pancreatic metastases may occur years after the start of treatment of a neoplasm of another organ or may be the initial manifestation of an unidentified primary tumor. The most commonly reported primary sites for pancreatic metastases are the kidneys, lungs, breast, bowel, and skin (melanoma).

Dysregulation of glycerophospholipid metabolism during Behçet's disease contributes to a pro-inflammatory phenotype of circulating monocytes.

Behçet's disease (BD) is a relapsing, multisystem and inflammatory condition characterized by systemic vasculitis of small and large vessels. Although the etiopathogenesis of BD remains unknown, immune-mediated mechanisms play a major role in the development of the disease. BD patients present leukocyte infiltration in the mucocutaneous lesions as well as neutrophil hyperactivation.

Aged biochar changed copper availability and distribution among soil fractions and influenced corn seed germination in a copper-contaminated soil.

Biochar has been recommended as a multi-beneficial amendment for the in situ remediation of heavy metals contaminated soils due to its high recalcitrance, stability, specific surface area and retention capacity, which leads to a long-lasting influence on the immobilization of soil contaminants. The influence of biochar on the availability of heavy metals such as copper is not fully understood and may be related to a change in copper association with soils fractions. Therefore, a long-time laboratory incubation study was set up as a completely randomized design to test the effect of biochar from different sources (coconut husks-CHB, orange bagasse-OBB and sewage sludge-SSB) at two rates of application (30 and 60 t ha) on the distribution of copper in a copper-contaminated soil after 24 months incubation.

Is food insecurity related to health-care use, access and absenteeism?

Objective: Food insecurity (FI) is defined as uncertain access to healthy food in quantity and quality. We hypothesize that FI may be associated with greater health-care use and absenteeism because it may amplify the effect of diseases; also, FI may be associated with reduced health-care access because it reflects economic vulnerability. The present study estimates the association between FI and health-care use and access, and absenteeism.

for oral mucositis in patients with head and neck cancer: a protocol of a randomised clinical trial.

Introduction: Oral mucositis is an iatrogenic condition of erythematous inflammatory changes which tends to occur on buccal and labial surfaces, the ventral surface of the tongue, the floor of the mouth and the soft palate of patients receiving chemotherapy. This protocol of ongoing randomised parallel group clinical trial aims to access the therapeutic effect of an herbal gel containing 2.5% Verlot standardised extract on oral mucositis in patients with head and neck cancer compared with low-level laser therapy.

Reforming the Portuguese mental health system: an incentive-based approach.

Background: To promote an effective mental health system, the World Health Organization recommends the involvement of primary care in prevention and treatment of mild diseases and community-based care for serious mental illnesses. Despite a prevalence of lifetime mental health disorders above 30%, Portugal is failing to achieve such recommendations. It was argued that this failure is partly due to inadequate financing mechanisms of mental health care providers.

Resveratrol stimulates the metabolic reprogramming of human CD4 T cells to enhance effector function.

The polyphenol resveratrol activates the deacetylase Sirt1, resulting in various antioxidant, chemoprotectant, neuroprotective, cardioprotective, and anti-inflammatory properties. We found that at high concentrations of resveratrol, human CD4 T cells showed defective antigen receptor signaling and arrest at the G stage of the cell cycle, whereas at low concentrations, cells were readily activated and exhibited enhanced Sirt1 deacetylase activity. Nevertheless, low-dose resveratrol rapidly stimulated genotoxic stress in the T cells, which resulted in engagement of a DNA damage response pathway that depended on the kinase ATR [ataxia telangiectasia-mutated (ATM) and Rad3-related], but not ATM, and subsequently in premitotic cell cycle arrest.

Cell surface Glut1 levels distinguish human CD4 and CD8 T lymphocyte subsets with distinct effector functions.

CD4 and CD8 T lymphocyte activation requires the generation of sufficient energy to support new biosynthetic demands. Following T cell receptor (TCR) engagement, these requirements are met by an increased glycolysis, due, at least in part, to induction of the Glut1 glucose transporter. As Glut1 is upregulated on tumor cells in response to hypoxia, we assessed whether surface Glut1 levels regulate the antigen responsiveness of human T lymphocytes in both hypoxic and atmospheric oxygen conditions.

Glutamine-dependent α-ketoglutarate production regulates the balance between T helper 1 cell and regulatory T cell generation.

T cell activation requires that the cell meet increased energetic and biosynthetic demands. We showed that exogenous nutrient availability regulated the differentiation of naïve CD4(+) T cells into distinct subsets. Activation of naïve CD4(+) T cells under conditions of glutamine deprivation resulted in their differentiation into Foxp3(+) (forkhead box P3-positive) regulatory T (Treg) cells, which had suppressor function in vivo.

Rhizosphere characteristics of two arsenic hyperaccumulating Pteris ferns.

Better understanding of the processes controlling arsenic bioavailability in the rhizosphere is important to enhance plant arsenic accumulation by hyperaccumulators. This greenhouse experiment was conducted to evaluate the chemical characteristics of the rhizosphere of two arsenic hyperaccumulators Pterisvittata and Pterisbiaurita. They were grown for 8 weeks in rhizopots containing arsenic-contaminated soils (153 and 266 mg kg(-1) arsenic).
