The role of point-of-care testing (POCT) out of hospital, especially in home care and ambulatory care settings, is an issue meriting further research. We reviewed studies reporting cardiovascular events as a result of the implementation of B-type natriuretic peptide or N-terminal pro B-type natriuretic peptide POCT (BNP/NT-proBNP POCT) for heart disease patients in the settings.
Life-sustaining treatment (LST) decisions for patients and caregivers at the end-of-life (EOL) process are supported by the "Act on Hospice and Palliative Care and Decisions on LST for Patients at the EOL," enforced in February 2018. It remains unclear whether the act changes EOL decisions and LST implementation in clinical practice. For this study, we investigated patients' decision-making regarding LSTs during the EOL process since the act's enforcement.
N-terminal pro-brain natriuretic peptide (NT-proBNP) is a widely used point-of-care (POC) cardiac biomarker in human medicine. Canine NT-proBNP is used less in veterinary medicine, possibly due to the lack of a POC canine NT-proBNP assay resulting in temporal delay, increased degradation in transport, and high reported variability in the available assay. A new quantitative POC analyzer allows fast, onsite measurement of NT-proBNP, minimizing preanalytical error and reducing variability.
Establishing and designating specialized hospice palliative care units (HPCUs) has been an important part of national policy to promote hospice palliative care in Korea in the recent decade. However, few studies have sought to identify patterns and barriers for utilizing HPCU over the period of national policy implementation. We aimed to investigate factors related with utilizing HPCU for terminal cancer patients after consultation with a palliative care team (PCT).
An accurate prediction of mortality in end-of-life care is crucial but presents challenges. Existing prognostic tools demonstrate moderate performance in predicting survival across various time frames, primarily in in-hospital settings and single-time evaluations. However, these tools may fail to capture the individualized and diverse trajectories of patients. Limited evidence exists regarding the use of artificial intelligence (AI) and wearable devices, specifically among patients with cancer at the end of life.
Background: More than 50% of patients worldwide die in hospitals and end-of-life care is costly. We aimed to explore whether support from the palliative team can influence end-of-life costs. Methods: This was a descriptive retrospective case-control study conducted at a Czech tertiary hospital. We explored the difference in daily hospital costs between patients who died with and without the support of the hospital palliative care team from January 2019 to April 2020. Big data from registries of routine visits were used for case-control matching. As secondary outcomes, we compared the groups over the duration of the terminal hospitalization, intensive care unit (ICU) days, intravenous antibiotics, magnetic resonance imaging/computed tomography scans, oncological treatment in the last month of life, and documentation of the dying phase. Standard descriptive statistics were used to describe the data, and differences between the case and control groups were tested using Fisher's exact test for categorical variables and the Mann-Whitney U test for numerical data. Results: In total, 213 dyads were identified. The average daily costs were three times lower in the palliative group (4392.4 CZK per day = 171.3 EUR) than in the nonpalliative group (13992.8 CZK per day = 545.8 EUR), and the difference was probably associated with the shorter time spent in the ICU (16% vs. 33% of hospital days). Conclusions: We showed that the integration of the palliative care team in the dying phase can be cost saving. These data could support the implementation of hospital palliative care in developing countries.
Ultraviolet (UV) irradiation is a potent inducer for skin photoaging. This paper investigated the anti-photoaging effects of the acetylated and amidated hexapeptide (AAH), originally identified from Spirulina platensis, in (Ultraviolet B) UVB-irradiated Human immortalized keratinocytes (Hacats) and mice. The results demonstrated that AAH had much lower toxicity on Hacats than the positive matrixyl (81.52% vs. 5.32%). Moreover, AAH reduced MDA content by 49%; increased SOD, CAT, and GSH-Px activities by 103%, 49%, and 116%, respectively; decreased MMP-1 and MMP-3 expressions by 27% and 29%, respectively, compared to UVB-irradiated mice. Employing isobaric tags for relative and absolute quantitation (iTRAQ)-based proteomics, 60 differential proteins were identified, and major metabolic pathways were determined. Network analysis indicated that these differential proteins were mapped into an interaction network composed of two core sub-networks. Collectively, AAH is protective against UVB-induced skin photoaging and has potential application in skin care cosmetics.
Fibronectin (FN) is known to be a large multifunction glycoprotein with binding sites for many substances, including N-terminal and C-terminal heparin-binding domains. We investigated the effects of highly purified rhFNHN29 and rhFNHC36 polypeptides originally cloned from the two heparin-binding domains on the adhesion and invasion of highly metastatic human hepatocellular carcinoma cells (MHCC97H) and analyzed the underlying mechanism involved.
Survival estimates are very important to patients with terminal cancer. The C-reactive protein (CRP)/albumin ratio is associated with cancer outcomes. However, few studies have investigated the dose-response association in terminal cancer patients. Therefore, we aimed to evaluate the association between the CRP/albumin ratio and mortality in terminal cancer patients using a longitudinal analysis. We retrospectively investigated the electronic medical records of 435 inpatients with terminal cancer admitted to the palliative care unit of Yeouido St. Mary's Hospital between October 8, 2015, and January 17, 2018. In total, 382 patients with terminal cancer were enrolled in the study. The serum CRP/albumin ratio measured at admission had a linear dose-response relationship with the risk of death among the terminal cancer patients (P for linearity = .011). The multivariate analyses showed that the CRP/albumin ratio was an independent prognostic factor (Model 1, CRP/albumin ratio >48.53 × 10: HR = 2.68, 95% CI = 1.82-3.93; Model 2, tertile 2: HR = 1.91, 95% CI = 1.31-2.82 and tertile 3: HR = 3.66, 95% CI = 2.24-5.97). The relationship between a high CRP/albumin ratio and poor survival was a flat L-shape for survival time with an inflection point at approximately 15 days, while the relationship was not significant in terminal cancer patients who survived beyond 30 days. This study demonstrated that high CRP/albumin ratios are significantly and independently associated with the short-term survival prognosis of terminal cancer patients within 30 days.
The epidermis serves as a critical protective barrier between the internal and external environment of the human body. Its remarkable barrier function is established through the keratinocyte (KC) terminal differentiation program. The transcription factors specifically regulating terminal differentiation remain largely unknown. Using a RNA-sequencing (RNA-seq) profiling approach, we found that forkhead box c 1 (FOXC1) was significantly up-regulated in human normal primary KC during the course of differentiation. This observation was validated in human normal primary KC from several different donors and human skin biopsies. Silencing FOXC1 in human normal primary KC undergoing differentiation led to significant down-regulation of late terminal differentiation genes markers including epidermal differentiation complex genes, keratinization genes, sphingolipid/ceramide metabolic process genes and epidermal specific cell-cell adhesion genes. We further demonstrated that FOXC1 works down-stream of ZNF750 and KLF4, and upstream of GRHL3. Thus, this study defines FOXC1 as a regulator specific for KC terminal differentiation and establishes its potential position in the genetic regulatory network.
Introduction Kawasaki disease (KD) is an idiopathic, acute systemic vasculitis typically affecting medium-sized blood vessels with an inclination towards the coronary arteries. There is no specific diagnostic test established for it yet. Hence, our study aims to evaluate serum N-terminal pro-brain natriuretic peptide (NT-proBNP), hydrogen sulfide (H2S), and interleukin-6 (IL-6) levels as potential diagnostic tools in children with KD and determine its relationship with the development of coronary artery lesions (CAL) in the pediatric population visiting a tertiary care hospital in Karachi. Methods A prospective observational study was performed on a sample of 500 children at a tertiary care hospital over a period of two years from June 2017 to June 2019. Blood samples were collected from two groups labeled CAL and non-coronary artery lesion (NCAL), and different biomarkers including NT-proBNP, IL-6, and H2S were compared between them to predict the diagnostic properties of each marker. Results Among the 500 children, 50% were between the age of one to five years. All presented with fever and varying degrees of associated symptoms. On lab investigations, levels of NT-proBNP and IL-6 during the acute phase of the disease were found to be higher in the CAL group than the NCAL and control groups (p<0.001). However, H2S levels during the acute attack were significantly lower in the CAL group when compared to the NCAL or control groups (p<0.001). Conclusion Elevated levels of NT-proBNP and IL-6 can be utilized as potential clinical markers for identifying children at risk of developing CAL as a complication of KD. Reduced H2S levels are also proposed as an indicator of progress towards CAL and should be considered in reaching a diagnosis.
Effective palliative care is one of the most valuable skills a physician may acquire. It involves not only control of physical symptoms, but relief of emotional symptoms. Relief of emotional symptoms requires truth telling in a context of supportive, skillful communication. Important communication skills include empathy, legitimation, support, partnership, and respect. Using these skills and the development of a limited treatment plan, along with pharmacological intervention, when necessary, to treat anxiety, depression, and confusion, may provide a significant measure of relief for the suffering that often accompanies terminal cancer.
The potential of rapid point-of-care (POC) tests has been subject of doubt due to an eventual risk of production errors. The aim was therefore to evaluate the two separate production lots of a commercial POC lateral flow test, intended for the detection of IgM and IgG against the SARS-CoV-2 spike protein (S1). Control samples consisted of serum from individuals with confirmed SARS-CoV-2 infection and pre-COVID-19 negative sera gathered from a biobank. The presence of anti-S1 IgM/IgG in the sera was verified by an in-house Luminex-based serological assay (COVID-19 SIA). One hundred samples were verified as positive for anti-S1 IgG and 74 for anti-S1 IgM. Two hundred samples were verified as negative for anti-S1 IgM/IgG. For the two lots of the POC-test, the sensitivities were 93.2% and 87.8% for IgM and 93.0% and 100% for IgG. The specificities were 100% for IgM and 99.5% for IgG. The positive predictive value was 100% for IgM and 98.9% and 99.0% for IgG. The negative predictive value was 97.6% and 95.7% for IgM, and 96.6% and 100% for IgG. The evaluated POC-test is suitable to assess anti-SARS-CoV-2 S1 IgM and IgG, as a measure of previous virus exposure on an individual level. The external validation of separate lots of rapid POC-tests is encouraged to ensure high sensitivity before market introduction.
A rat model of levodopa-induced dyskinesia (LID) showed enlarged axon terminals of striatal direct pathway neurons in the internal segment of the globus pallidus (GPi) with excessive gamma-aminobutyric acid (GABA) storage in them. Massive GABA release to GPi upon levodopa administration determines the emergence of LID.
