The relationship between hemoglobin-to-red cell distribution width (RDW) ratio (HRR) and mortality in stroke patients.

In recent years, many studies have shown that hemoglobin to red cell distribution width ratio (HRR), which is the ratio of hemoglobin (Hb) to red cell distribution width (RDW), is associated with inflammation. Inflammation is linked to both the development of stroke and the severe effects that follow. Therefore, the relationship between the HRR and mortality in patients with stroke was investigated in our study. 127 stroke patients who visited the emergency department between March 1, 2023, and June 1, 2023, were retrospectively evaluated. The National Institutes of Health Stroke Scale (NIHSS) was used to measure stroke severity. All stroke patients were divided into four groups: patients with atrial fibrillation (AF), those without AF, and those with low and high HRR. HRR levels were compared between patients with and without AF. The relationship between HRR and mortality was also analyzed. HRR levels were found to be significantly lower in patients with AF compared to those without AF (p<0.05 for all). NIHSS, requirement for mechanical ventilation, and mortality rate were significantly higher in the low HRR (HRR≤0.795) group compared to the high HRR group (HRR>0.795) (p<0.05 for all). HRR outperformed Hb and RDW alone in predicting mortality (AUC; 0.975, 0.952, 0.911, respectively). Additionally, a significant positive correlation was found between HRR levels and NIHSS (p<0.001). Low HRR measured on admission is a useful marker for predicting mortality and determining the severity of stroke.

Performance Improvement Program Review of Institutional Massive Transfusion Protocol Adherence: An Opportunity for Improvement.

Given the acuity of patients who receive MTPs and the resources they require, MTPs are a compelling target for performance improvement. This study evaluated adherence with our MTP's plasma:red blood cell ratio (FFPR) of 1:2 and platelet:red blood cell ratio (PLTR) of 1:12, to test the hypothesis that ratio adherence is associated with lower inpatient mortality. The registry of an urban level I trauma center was queried for adult patients who received at least 6 units of packed red blood cells within 4 hours of presentation. Patients were excluded for interfacility transfer, cardiac arrest during the prehospital phase or within one hour of arrival, or for head AIS ≥5. Univariate analysis and multiple logistic regressions were performed to identify variables associated with early transfusion protocol noncompliance and the effect on inpatient mortality. Three hundred and eighty-three patients were included, with mean ISS of 25.9 ± 13.3 and inpatient mortality of 28.5%. Increasing age, ISS, INR, and total units of blood product transfused were associated with increased odds of mortality, while an increase in revised trauma score was associated with a decreased odds ratio of mortality. Achieving our goal ratios were protective against mortality, with OR of .451 (P = .013) and .402 (P=.003), respectively. Large proportions of critically injured patients were transfused fewer units of plasma and platelets than our MTP dictated; failure to achieve intended ratios at 4 hours was strongly associated with inpatient mortality. MTP processes and outcomes should be critically assessed on a regular basis as part of a mature performance improvement program to ensure protocol adherence and optimal patient outcome.

Effect of Red and Blue Light on the Growth and Antioxidant Activity of Alfalfa Sprouts

Alfalfa sprouts are popular as a gourmet vegetable that contains a variety of antioxidants with anti-cancer and anti-coronary heart disease properties. In this study, under a photosynthetic photon flux density (PPFD) of 30 mol·L−1 photoperiod of 12 h for 3 days, and a temperature of 25 ± 2 °C, we investigated the effects of different light qualities on the growth, nutritional quality and antioxidant activity of alfalfa sprouts by modulating LEDs with different red and blue ratios, and searched for suitable light-quality conditions for alfalfa sprout growth. The experimental results showed that the dark treatment favored the growth of alfalfa sprout hypocotyls and the increase of soluble sugar content; alfalfa fresh weight was the largest under the white and red light treatments; nitrate content was the lowest in the treatment with a red-to-blue ratio of 2:2 (2R2B); soluble proteins and total phenolic content were the highest in the treatment with red-to-blue ratio of 1:3 (1R3B); and the total antioxidant activity of sprouts was the highest in the blue light treatment.

The Predictive Value of Hemoglobin to Red Cell Blood Distribution Width Ratio Combined with Serum Sodium for MACE of Acute Heart Failure with Preserved Ejection Fraction in Elderly Patients.

To investigate the predictive value of hemoglobin (Hb) to red blood cell distribution width (RDW) (Hb/RDW) ratio in combination with serum sodium for major adverse cardiovascular events (MACE) in elderly acute heart failure patients with preserved ejection fraction at 30 days after discharge. 130 elderly acute heart failure patients with preserved ejection fraction were enrolled and followed up at 30 days after discharge. They were classified into the MACE group (n=11) and none-MACE group (n=119). On the day of admission, clinical baseline characteristics were measured and results from laboratory tests were gathered. The correlation and predictive value of Hb/RDW and serum sodium with the occurrence of MACE at 30 days after discharge in acute heart failure patients with preserved ejection fraction in the elderly were analyzed. Spearman correlation analysis showed that the occurrence of MACE was negatively correlated with Hb/RDW, serum sodium (r=-0.209, r=0.291, p<0.05) and Hb/RDW (OR=0.484, 95% CI:0.254, 0.922), serum sodium (OR=0.779, 95% CI:0.646,0.939) were independent risk factors (p<0.05) analyzed by multifactorial logistic. Receiver operating characteristic curves (ROC) analysis showed that the area under the curve (AUC) for the prediction of MACE by Hb/RDW was 0.73, with an optimal threshold of 9.28, sensitivity 81.80%, specificity 70.60%, positive predictive value (PPV) 20.50%, negative predictive value (NPV) 97.70%; the AUC of serum sodium for predicting the occurrence of MACE was 0.76, with an optimal threshold of 140.35 mmol/L, sensitivity 90.90%, specificity 57.10%, PPV 16.40%, NPV 98.60%; and the AUC of Hb/RDW combined serum sodium to predict the occurrence of MACE was 0.83, with sensitivity 90.90%, specificity 78.20%, PPV 27.80% and NPV 98.90%. Hb/RDW and serum sodium had negative correlation with MACE and were independent risk factors of 30-day MACE; Hb/RDW combined with serum sodium can predict 30-day MACE occurrence in elderly acute heart failure patients with preserved ejection fraction.

Red, blue or mix: choice of optimal light qualities for enhanced plant growth and development through in silico analysis

Abstract In smart greenhouse farming, the impact of light qualities on plant growth and development is crucial but lacks systematic identification of optimal combinations. This study addresses this gap by analysing various light properties’ effects (photoperiod, intensity, ratio, light–dark order) on Arabidopsis thaliana growth using days-to-flower (DTF) and hypocotyl length as proxies to measure plant growth and development. After establishing suitable ranges through a comprehensive literature review, these properties varied within those ranges. Compared to white light, a 16-h cycle of blue light reduces DTF and hypocotyl length by 12 % and 3 %, respectively. Interestingly, similar results can be achieved using a shorter photoperiod of 14-h light (composed of 8 h of a mixture of 66.7 μmol m−2s−1 red and 800 μmol m−2s−1 blue lights (i.e. blue:red ratio of 12:1) followed by 6 h of monochromatic red light and 10-h dark. These findings offer potential for efficient growth light recipes in smart greenhouse farming, optimizing productivity while minimizing energy consumption.

Exploring the potential of lanthanide-doped oxyfluoride materials for bright green upconversion and their promising applications towards temperature sensing and drug delivery.

The most efficient upconversion (UC) materials reported to date are based on fluoride hosts with low phonon energies, which reduce the amount of nonradiative transitions. In particular, NaYF4 doped with Yb3+ and Er3+ at appropriate ratios is known as one of the most efficient UC phosphors. However, its low thermal stability limits its use for certain applications. On the other hand, oxide hosts exhibit better thermal stability, yet they have higher phonon energies and are thus prone to lower UC efficiencies. As a result, developing host nanomaterials that combine the robustness of oxides with the high upconversion efficiencies of fluorides remains an intriguing prospect. Herein, we demonstrate the formation of ytrrium doped oxyfluoride (YOF:Yb3+,Er3+) particles, which are prepared by growing a NaYF4:Yb3+,Er3+ layer around SiO2 spherical particles and consecutively applying a high-temperature annealing step followed by the removal of SiO2 template. Our interest lies in employing these materials as Boltzmann type physiological range luminescence thermometers, but their weak green emission is a drawback. To overcome this issue, and engineer materials suitable for Boltzmann type thermometry, we have studied the effect of introducing different metal ion co-dopants (Gd3+, Li+ or Mn2+) into the YOF:Yb3+,Er3+ particles, focusing on the overall emission intensity, as well as the green to red ratio, upon 975 nm laser excitation. These materials are explored for their use as ratiometric thermometers, and further also as drug carriers, including their simultaneous use for these two applications. The investigation also includes examining their level of toxicity towards specific human cells - normal human dermal fibroblasts (NHDFs) - to evaluate their potential use for biological applications.

Physical Properties Investigation on Sunscreens with Red Dragon Fruit Peel Extract

Red dragon fruit peel extract is reported as an active ingredient in sunscreen because of its ability to protect the skin. UV exposure to the skin can cause reddish skin to develop skin cancer. This study aimed to determine the characteristics of the cream made from ZnO and red dragon fruit peel extracts (Hylocereus costaricensis), such as sun protection factor (SPF), pH, stability, viscosity, spreadability, and adhesion. Red dragon fruit peel extract was obtained by maceration using methanol, and DPPH-scavenging activity resulted in an IC50 of 0.96 μg/mL. Measurement of diffuse UV-vis reflectance shows that ZnO has absorption at λex 385 nm, which correlates with a bandgap energy of 3.22 eV. F1 formulation cream (red dragon fruit peel extract and ZnO ratio of 0:1) has the highest SPF value of 17. The Kruskal-Wallis test shows that there is a significant difference in adhesion between the F1 formulation cream with F2 (p-value = 0.002) and F4 (p-value = 0.03).

The ratio of lymphocyte/red blood cells and platelets/lymphocytes are predictive biomarkers for lymph node metastasis in patients with breast cancer.

Axillary lymph node metastasis (LNM) affects the progression of breast cancer. However, it is difficult to preoperatively diagnose axillary lymph node status with high sensitivity. Therefore, we hypothesized that platelets/lymphocytes ratio (PLR) and lymphocytes/ red blood cells ratio (LRR) might help in the prognosis of lymph node metastasis in T1-T2 breast cancer. 166 patients (Chang Ning Maternity & Infant Health Institute) were included in our study, and the associations of PLR and LPR with lymph node metastasis were investigated. Peripheral blood was collected one week before the surgery, and the patients were divided into different categories based on their PLR and LRR. The incidence of LNM was significantly increased in the high PLR group (p= 0.002) compared with the low PLR group; LNM was also significantly increased in the low LRR group (p= 0.036) compared with the high LPR group. Further, our study revealed that high PLR (p< 0.001, OR = 4.397, 95% CI = 2.005-9.645), low LRR (p= 0.017, OR = 0.336, 95%CI = 0.136-0.825) and high clinical T stage (p< 0.001, OR = 3.929, 95%CI = 1.913-8.071) are independent predictors of LNM. PLR and LRR could be identified as predictors of LNM in patients with T1/T2 breast cancer.

Impacts of ultraviolet and photosynthetically active radiations on photosynthetic efficiency and antioxidant systems of the cyanobacterium Spirulina subsalsa HKAR-19.

This study summarizes the response of cyanobacterium Spirulina subsalsa HKAR-19 under simulated light conditions of photosynthetically active radiation (PAR), PAR+UV-A (PA), and PAR+UV-A+UV-B (PAB). Exposure to UV radiation caused a significant (P < 0.05) decrease in chlorophyll a, phycocyanin, and total protein. In contrast, total carotene content increased significantly (P < 0.05) under PA and PAB with increasing irradiation time. The photosynthetic efficiency of photosystem II also decreased significantly in PA and PAB radiation. We havealso recorded a decrease in the fluorescence emission intensity of phycocyanin under PA and PAB exposure. The phycocyanin fluorescence shifted towards shorter wavelengths (blue-shift) after 72h of PA and PAB exposure. Intracellular reactive oxygen species (ROS) levels increased significantly in PA and PAB. Fluorescence microscopic images showed an increase in green fluorescence, indicating ROS generation in UV radiation. We havealso quantified ROS generation using green and red fluorescence ratio represented as G/R ratio. A 2-6-foldincrease in antioxidative enzymes activity was observed to overcome the damaging effects caused by UV stress as compared to untreated control cultures. The lipid peroxidation was assessed in terms of malondialdehyde content which increases significantly (P < 0.05) as the duration of exposure increases. These results suggest that a combined effect of PAR, UV-A, and UV-B was more deleterious than an individual one.

Beyond Traditional Treatments: Exploring Cutting-Edge Approaches for Androgenetic Alopecia

Androgenetic Alopecia is a genetically predetermined disorder resulting in hair loss from an excessive sensitivity to androgens. Several treatment options have been investigated for androgenetic alopecia, yet only topical minoxidil and finasteride have received approval from the US Food and Drug Administration. This review article examines and evaluates the efficacy of new, cutting-edge techniques for treating AGA, including Low-Level Laser Therapy, Platelet Rich Plasma Therapy, Micro needling, and Topical Growth Factors and Peptides. Several essential factors are stimulated by minoxidil, including vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), and insulin-like growth factor (IGF)-1. IGF-1 also plays a significant role in regulating follicular differentiation, which makes it a vital regulator of hair follicle development and function. Low-level laser therapy (LLLT) uses low-intensity light at red or near-infrared wavelengths to induce changes in cellular activity, which improves blood circulation, reduces inflammation, and boosts cellular energy, ultimately leading to improved hair follicle density and diameter. Platelet-rich plasma therapy (PRP) is used in dermatology for acne scar treatment, lipid transplantation, wound healing, and hair regeneration. It involves a centrifugation process that increases the platelet concentration and reduces the red blood cell ratio. Micro needling is a minimally invasive procedure that stimulates the production of collagen, growth factors, and neovascularization, which promotes tissue rejuvenation. It is most utilized for individuals who are unable to achieve successful results using medical therapy. These approaches have shown positive outcomes in terms of hair regrowth, improved hair density, increased hair shaft thickness, and patient satisfaction.

Objective: To determine the association of red cell distribution width (RDW)and neutrophil-lymphocyte ratio (NLR)with the severity of rheumatoid arthritis by using DAS28 ESR. Additionally, toxic granulations were assessed as an indicator of disease severity. Study Design: Cross-sectional study. Place and Duration of Study: Rheumatology Outpatient Department, Federal Government Polyclinic Hospital, IslamabadPakistan, from Dec 2020 to Jun 2021. Methodology: Two hundred ninety rheumatoid arthritis patients were included. DAS 28 ESR was calculated using the DAS 28 ESR calculator, and RDW and NLR were extracted from the complete blood picture and peripheral smears. Results: There were 238(82.1%) female and 52 17.9%) male study participants. The mean age of patients was 45.2±12.8. The mean RDW, NLR and DAS 28 ESR in the study were 45.67±4.25, 2.93±1.35 and 4.29±1.25, respectively. Toxic granulations on peripheral smears were also found in 188(64.8%) patients. A significant positive association was found using the Spearman rho correlation between the DAS28 ESR score, RDW and NLR (p-value 0.024 and &lt;0.001, respectively). Conclusion: Red cell distribution width and neutrophil-lymphocyte ratio, along with toxic granulations, can be used as reliable biomarkers of inflammation in rheumatoid arthritis patients. Values higher than the reference range indicate higher disease severity.

Prognostic significance of prognostic nutritional index and hemoglobin to red cell distribution width ratio in metastatic colorectal cancer patients

Aims: Malnutrition and systemic inflammation are poor prognostic factors in cancer. Prognostic nutritional index (PNI) and Hemoglobin to red blood cell distribution witdh (HRR) are considered indicators of malnutrition and systemic inflammation. We aimed to investigate the prognostic importance of PNI and HRR on metastatic colorectal cancer survival.&#x0D; Methods: We retrospectively reviewed all patients diagnosed with metastatic colorectal cancer treated at Kayseri City Training and Research Hospital and Erciyes University Medical School. PNI is calculated as (serum albumin (g/L) +5 x total lymphocyte count (10⁹/L)). And HRR was calculated as the ratio of hemoglobin (g/dl) and RDW (%). PNI was divided into two groups based on the cut off points 46.175 as PNI high and low. And we compared these two groups according to general characteristics and overall survival. We performed another comparision between HRR low and high groups based on the cut off points 0.8675 according to general characteristics and overall survival. Kaplan Meier method was used to analyse overall survival and compared survival rates with the log-rank test.&#x0D; Results: We reviewed 346 metastatic colorectal cancer patients and we included 145 of them who fit to inclusion criteria to the study. Univariate analysis revealed that presence of initially metastatic disease, right located tumor, low HRR, low PNI were independent prognostic markers of poor overall survival. In multivariate analysis, presence of initially metastatic disease and low PNI remain statistically significant independent prognostic markers of poor survival. The median overall survival was statistically longer in HRR and PNI low groups than high groups.&#x0D; Conclusion: Both PNI and HRR are associated with poor overall survival in metastatic colorectal cancer.

Strawberry ripeness classification method in facility environment based on red color ratio of fruit rind

Strawberry detection and ripeness classification are important concerns in robotic harvesting, as precondition for efficient and nondestructive picking. However, the different sizes and overlap of strawberries complicate detection, and research on strawberry ripeness classification is lacking. Therefore, this study proposes the red color ratio as a new parameter for strawberry ripeness quantification. This parameter considers the proportion of the strawberry red area as a key factor. First, an adaptive strawberry feature augmentation network (ASFA-net) is proposed to generate masks for the strawberries. ASFA-net uses the shifted window (Swin) Transformer as the backbone network for strawberry feature extraction and employs a feature pyramid network along with the proposed strawberry feature adaptive fusion module, to augment the features. The proposed decoupled head network is then applied to generate the final results. Second, the red region within the mask of ripe strawberries is segmented based on hue, saturation, and value (HSV) to calculate the proportion of the red area of individual strawberries. ASFA-net was verified on a home-made strawberry dataset. The results show that ASFA-net can detect strawberries accurately and efficiently with mean average precision of 95.91 ± 0.64 % and mean intersection over union of 90.15 ± 1.49 %. The strawberry ripeness classification method exhibited good performance with an accuracy of 95.94 ± 1.40 %, false positive rate of 3.09 ± 0.46 %, and false negative rate of 4.22 ± 1.68 %. The purpose of this study is to establish a method for simultaneous strawberry detection and ripeness classification in a facility environment, to provide a new reference method for the vision system of robots.

Synergistic Effects of Red Clay and Lime for Improving Phyllite Soil

Phyllite soil and red clay belong to the soils that negatively impact the engineering performance of railway subgrade and may cause subgrade bulges, uneven subgrade settlement, and other subgrade distresses. In order to make full use of these two soils, a collaborative improvement plan was proposed. A series of tests were conducted to analyze the synergistic effects of lime and red clay on the improvement of phyllite soil. The tests included the no loading swelling ratio, swelling pressure, consolidation, and direct shear tests. Additionally, scanning electron microscopy was used to investigate the role of lime and red clay in soil improvement. The test results show that a red clay ratio of 60% + lime content of 3% is the optimal composite improvement scheme. The scheme led to a 93% reduction in the no loading swelling ratio and an 88% reduction in swelling pressure. Additionally, cohesion, the internal friction angle, and the compression modulus increased by 345%, 73%, and 373%. Red clay and lime had weak synergistic improvement effects on the no loading swelling ratio, the swelling pressure, and the internal friction angle of phyllite soil, that is, the synergistic improvement effect of red clay and lime was less than the sum of the single improvement effect but greater than the single improvement effect. Red clay and lime had a strong synergistic improvement effect on the cohesion and the compression modulus of phyllite, that is, the synergistic improvement effect of red clay and lime was greater than the sum of the single improvement effect. The microstructure analysis test results show that red clay can fill the pores of phyllite soil and improve its immediate strength. Through hardening and cementation, lime can enhance the strength of phyllite soil as well as address the issue of the reduced engineering properties of phyllite soil and red clay when exposed to water. Red clay and lime promote each other’s reactions and have a synergistic improvement effect on phyllite soil.

The influence of the ratio of red and far red on the growth of seedlings of cucumber Cucumis sativus L. variety Courage

Far red light is not included in the range of photosynthetically active radiation, but plays an important role for plants as an informational indicator of the state of the environment. Plants evolved a system of receptors for recording the amount of far red light and a set of responses to changes in the red/far red ratio. This paper describes the results of an experiment on cultivation of cucumber seedlings under different light conditions by the red/far red ratio factor. Significant differences in the length of internodes were revealed in cucumber plants grown under additional illumination with far red compared to the control.

The relationship between hemoglobin/red blood cell distribution width ratio and mortality in patients with intracranial hemorrhage: a possible protective effect for the elderly?

Intracranial hemorrhage (ICH) is a neurological emergency with a poor prognosis. This study aimed to understand the association between hemoglobin levels, red blood cell distribution width ratio (HRR), and mortality in patients with ICH. Information on patients with ICH was extracted from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. Cox proportional risk models were used to assess the relationship between HRR and 28-day and 90-day mortality, and constructed by adjusting for relevant covariates. Segmented regression models and smoothing curves were used to analyze the linear relationship between HRR and mortality. This study recruited 4,716 patients with ICH. The HRR Q4 group was negatively associated with the 28- and 90-day mortality. For patients aged > 65years, the right-hand threshold inflection points of the HRR were 0.92 and 0.93, respectively, which were negatively associated with 28-day mortality (HR:0.06, 95% CI 0.01, 0.35, p = 0.0016) and with 90-day mortality (p = 0.0006). In the non-linear model, both 28-day mortality (HR, 0.17; 95% CI 0.04-0.75, p = 0.0191; HRR > 0.89) and 90-day mortality (HR, 0.13; 95% CI 0.04-0.49, p = 0.0022; HRR > 0.85) were associated in men. In the subgroup analysis, the negative association between HRR and mortality was more pronounced in patients > 65years of age, as well as in patients with non-dementia, diabetes, and malignant cancer. We found a non-linear relationship between mortality and the HRR in elderly patients, and a higher HRR was negatively associated with mortality in patients with ICH.

Hemoglobin to red cell distribution width ratio: A predictor of clinical outcome and diuretic response in patients with acute heart failure

BackgroundHemoglobin to Red Cell Distribution Width Ratio (HRR) is a novel inflammatory marker in the prognostic assessment of tumors. Nevertheless, its focus on the cardiovascular field is relatively limited, particularly regarding its correlation with diuretic responses and clinical outcomes. MethodsThis is a secondary analysis of the Renal Optimization Strategies Evaluation (ROSE AHF) clinical trial. The outcomes of interest included all-cause death, rehospitalization and diuretic responses. Multivariable Cox proportional hazard regression and linear regression models were performed, respectively. Prognostic outcomes and diuretic response were further evaluated in ejection fraction (EF) subgroups (preserved EF ≥ 50% and reduced EF<50%). ResultsA total of 351 patients were included in the present study and further categorized according to HRR median (0.7131) value at admission: low HRR group (n = 176) and high HRR group (n = 175). High HRR were found to be independently associated with decreased risk of all-cause death (HR = 0.51; 95% CI,0.30–0.87, P = 0.013), reduced risk of developing all-caused death or rehospitalization (HR = 0.62; 95% CI,0.39–0.98, P = 0.039). Furthermore, high HRR indicated lower cumulative urine output (OR: -992.33, P = 0.004) and less weight loss (OR: 3.08, P < 0.001) within 72 h after diuresis. Subgroup analysis revealed no significant interaction effect between EF and HRR in prognostic impact or diuretic responses, and HRR was negatively correlated with plasma volume. ConclusionHigh HRR demonstrated a lower risk of developing adverse clinical outcomes and a poorer diuretic response that might be due to less volume overload in AHF patients.
