Both drugs counteracted these effects. In non-diabetic mice, only linagliptin accelerated recovery.These findings shed light on the interplay between obesity and T2D in stroke recovery. Moreover, they promote the use of rehabilitative strategies based on efficacious glycemia regulation, even if initiated days after stroke.Background Delays in referral for patients with colorectal cancer may occur if the presenting symptom is falsely attributed to a benign condition. Aim To investigate whether delays in referral from primary care are associated with a later stage of cancer at diagnosis and worse prognosis. Design and setting A national retrospective cohort study in England including adult patients with colorectal cancer identified from the cancer registry with linkage to Clinical Practice Research Datalink, who had been referred following presentation to their GP with a 'red flag' or 'non-specific' symptom. Method The hazard ratios (HR) of death were calculated for delays in referral of between 2 weeks and 3 months, and >3 months, compared with referrals within 2 weeks. Results A total of 4527 (63.5%) patients with colon cancer and 2603 (36.5%) patients with rectal cancer were included in the study. The percentage of patients presenting with red-flag symptoms who experienced a delay of >3 months before referral was 16.9% of those with colon cancer and 13.5% of those with rectal cancer, compared with 35.7% of patients with colon cancer and 42.9% of patients with rectal cancer who presented with non-specific symptoms. Patients referred after 3 months with red-flag symptoms demonstrated a significantly worse prognosis than patients who were referred within 2 weeks (colon cancer HR 1.53; 95% confidence interval [CI] = 1.29 to 1.81; rectal cancer HR 1.30; 95% CI = 1.06 to 1.60). This association was not seen for patients presenting with non-specific symptoms. Delays in referral were associated with a significantly higher proportion of late-stage cancers. Conclusion The first presentation to the GP provides a referral opportunity to identify the underlying cancer, which, if missed, is associated with a later stage in diagnosis and worse survival.Background Understanding barriers to safe opioid prescribing in primary care is critical amid the epidemic of prescription opioid abuse, misuse, and overdose in the US. Selleck Trichostatin A Educational outreach strategies, such as academic detailing (AD), provide a forum for identification of barriers to, and strategies to facilitate, safe opioid prescribing in primary care. Aim To identify barriers to safe opioid prescribing among primary care providers (PCPs) through AD. Design and setting Qualitative analysis of data was collected through an existing AD intervention to improve safe opioid prescribing in primary care. The AD intervention was delivered from June 2018 to August 2018 to licensed PCPs with prescriptive authority within a large independent health system in the metropolitan Chicagoland area. Method The AD intervention involved visits by trained detailers to PCPs who contemporaneously documented details from each visit via field notes. Using qualitative analysis, field notes were analysed to identify recurring themes related to opioid prescribing barriers. Results Detailer-entered field notes from 186 AD visits with PCPs were analysed. Barriers to safe opioid prescribing were organised into six themes 1) gaps in knowledge; 2) lack of prescription monitoring programme (PMP) utilisation; 3) patient pressures to prescribe opioids; 4) insurance coverage policies; 5) provider beliefs; and 6) health system pain management practices. Conclusion Barriers to safe opioid prescribing in primary care, identified through AD visits among this large group of PCPs, support the need for continued efforts to enhance pain-management education, maximise PMP utilisation, and increase access to, and affordability of, non-opioid treatments.Background The complex nature of heart failure (HF) management, often involving multidimensional care, is widely recognised, but overall health service utilisation by patients with HF has not previously been described. Aim To describe overall health service use by adults with HF living in a community setting. Design and setting Cross-sectional analysis of prevalent HF cases from January 2015 to December 2018 using an administrative dataset covering primary and secondary care, and 'other' (community, mental health, social care) services in North West London. Method Healthcare use of each service was described overall and by individual components of secondary care (such as, outpatient appointments), and 'other' services (such as, nursing contacts). Usage patterns were identified using k-means cluster analysis, using all distinct contacts for the whole study period, and visualised with a heatmap. Results A total of 39 301 patients with a prevalent diagnosis of HF between 1 January 2015 and 31 December 2018 were found. Of those, approximately 90% used health services during the study period, most commonly outpatient services, GP consultations, unplanned accident and emergency visits, and community services. Use of cardiology-specific services ranged from around 3% (cardiology-related community care) to around 20% (outpatient cardiology visits). GP consultations decreased by 11% over the study period. Five clusters of patients were identified, each with statistically significantly different care usage patterns and patient characteristics. Conclusion Patients with HF make heavy but heterogeneous use of services. Relatively low and falling use of GP consultations, and the apparently low uptake of community rehabilitation services by patients with HF, is concerning and suggests challenges in primary care access and integration of care.Global demand for phosphorus (P) requires new agronomic practices to address sustainability challenges while increasing food production. Foliar P fertilization could increase P use efficiency; however, leaf entry pathways for inorganic phosphate ion (Pi) uptake remain unknown and it is unclear whether foliar P applications can meet plant nutrient demands. We developed two techniques to trace foliar P uptake in P-deficient spring barley (Hordeum vulgare) and to monitor the effectiveness of the treatment on restoring P functionality. Firstly, a whole-leaf P status assay was developed using an Image PAM system;non-photochemical quenching (NPQ) was a proxy for P status, asP-deficient barley developed NPQ at a faster rate than P-sufficient barley.. The assay showed restoration of P functionality in P-deficient plants 24 h after foliar P application. Treated leaves reverted to P-deficiency after 7 d, while newly emerging leaves exhibited partial restoration compared to untreated P-deficient plants, indicating Pi remobilization. Secondly, vanadate (V) was tested as a possible foliar Pi analogue using high resolution laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS)elemental mapping. The strong co-localization of 51V and 31P signal intensities demonstrated that V was a sensitive and useful Pi tracer. V and Pi uptake predominantly occurred via fiber cells located above leaf veins, with pathways to the vascular tissue possibly facilitated by the bundle sheath extension. Minor indications of stomatal and cuticular Pi uptake were also observed. These techniques provided an approach to understand how Pi crosses the leaf surface and assimilates to meet plant nutrient demands.Uropathogenic E. coli (UPEC) is the leading cause of urinary tract infections (UTI). These bacteria undertake a multi-stage infection cycle involving invasion of and proliferation within urinary tract epithelial cells, leading to the rupture of the host cell and dispersal of the bacteria, some of which have a highly filamentous morphology. Here we established a microfluidics-based model of UPEC infection of immortalized human bladder epithelial cells that recapitulates the main stages of bacterial morphological changes during the acute infection cycle in vivo and allows the development and fate of individual cells to be monitored in real-time by fluorescence microscopy. The UPEC-infected bladder cells remained alive and mobile in non-confluent monolayers during the development of intracellular bacterial communities (IBCs). Switching from a flow of growth medium to human urine resulted in immobilization of both uninfected and infected bladder cells. IBCs continued to develop and then released many highly filamentous bacteria via an extrusion-like process, whereas others showed strong UPEC proliferation yet no detected filamentation. The filamentation response was dependent on the weak acidity of human urine and required component(s) in a low molecular-mass ( less then 3000 Da) fraction from a mildly dehydrated donor. The developmental fate for bacteria therefore appears to be controlled by multiple factors that act at the level of the whole IBC, suggesting that variable local environments or stochastic differentiation pathways influence IBC developmental fates during infection.Human rhinovirus (hRV) is frequently detected in the upper respiratory tract, and symptomatic infection is associated with increased nasopharyngeal bacterial load with subsequent development of secondary bacterial diseases. Nontypeable Haemophilus influenzae (NTHI) is a commensal bacterial species of the human nasopharynx however, in the context of prior or concurrent upper respiratory tract viral infection, this bacterium commonly causes multiple diseases throughout the upper and lower respiratory tracts. The present study was conducted to determine the mechanism(s) by which hRV infection promotes development of NTHI-induced diseases. We showed that hRV infection of polarized primary human airway epithelial cells resulted in increased adherence of NTHI, due in part to augmented expression of CEACAM1 and ICAM1, host cell receptors to which NTHI binds via engagement of multiple adhesins. Antibody blockade of these host cell receptors significantly reduced NTHI adherence. With a specific focus on the NTHI Type IV pilus (T4P) which we've previously shown binds to ICAM1, an essential adhesin and virulent determinant, we next showed that T4P-directed antibody blockade significantly reduced NTHI adherence to hRV-infected airway cells and further, that expression of this adhesin was required for the observed enhanced adherence. Collectively, these data provide a mechanism by which the 'common cold' promotes diseases due to NTHI and add further support for use of PilA (the majority subunit of T4P) as a vaccine antigen, as antibodies directed against PilA are expected to limit the notably increased bacterial load associated with hRV co-infection and thereby prevent secondary NTHI-induced diseases of the respiratory tract.C-type lectin receptors (CLRs) play key roles in anti-fungal defense. CLR-induced NF-κB is central to CLR functions in immunity and thus, molecules that control the amplitude of CLR-induced NF-κB could profoundly influence host defense against fungal pathogens. However, little is known about the mechanisms that negatively regulate CLR-induced NF-κB and molecules which act on the CLR family broadly, and which directly regulate acute CLR-signaling cascades remain unidentified. Here we identify the ubiquitin-editing enzyme A20 as a negative regulator of acute NF-κB activation downstream of multiple CLR pathways. Absence of A20 suppression results in exaggerated CLR responses in cells which are A20-deficient and also cells which are A20-haplosufficient, including multiple primary immune cells. Loss of a single allele of A20 results in enhanced defense against systemic Candida albicans infection and prolonged host survival. Thus, A20 restricts CLR-induced innate immune responses in vivo and is a suppressor of host defense against systemic fungal infection.
