Comparative histological analysis of spleens in pediatric patients with hemolytic anemias: Insights into the pathophysiological mechanisms of spleen destruction in sickle cell anemia.

While sickle cell anemia (SCA) and hereditary spherocytosis (HS) share common features of increased spleen erythrophagocytosis due to increased red blood cell (RBC) turnover, SCA is specifically characterized by susceptibility to infections. In this study, histological lesions in the spleens of pediatric patients with SCA were analyzed, in close correlation with past clinical history and comparatively to HS, healthy and transfused β-thalassemia patients (TDT). An evaluation of red pulp elementary lesions (red pulp fibrosis, iron deposition, number of Gandy-Gamna, and RBC trapping) combined into a severity score was established, as well as B-cell follicles analysis. Quantification on digitalized slides of iron deposition, RBC trapping, and red pulp fibrosis was additionally performed. Spleens from 22 children with SCA, eight with HS, eight with TDT, and three healthy controls (HC) were analyzed. Median age at splenectomy was not different between SCA and HS patients, 6.05 years (range: 4.5-16.0) versus 4.75 (range: 2.2-9.5). Marked heterogeneity was found in SCA spleens in contrast to other conditions. Contrary to previous reports, B-cell follicles were generally preserved in SCA. While RBC trapping was significantly increased in both SCA and HS (compared to TDT and HC), quantitative fibrosis and overall red pulp severity score were significantly increased in SCA spleens compared to other conditions. Moreover, there was an inverse correlation between quantitative fibrosis and number of B-cell follicles, linking these two compartments as well as spleen fibrosis to infectious susceptibility in SCA, potentially through impaired red pulp macrophage scavenging and B-cell subpopulations defects.

Manual therapy and exercise effects on inflammatory cytokines: a narrative overview.

Matching disease and treatment mechanisms is a goal of the Precision Medicine Initiative. Pro- and anti-inflammatory cytokines (e.g., Tumor Necrosis Factor-alpha, Transforming Growth Factor-beta, and Interleukin-2, 10, and 12) have gained a significant amount of interest in their potential role in persistent pain for musculoskeletal (MSK) conditions. Manual therapy (MT) and exercise are two guideline-recommended approaches for treating MSK conditions. The objective of this narrative overview was to investigate of the effects of MT and exercise on pro- and anti-inflammatory cytokines and determine the factors that lead to variability in results. Two reviewers evaluated the direction and variabilities of MT and exercise literature. A red, yellow, and green light scoring system was used to define consistencies. Consistencies in responses were seen with acute and chronic exercise and both pro- and anti-inflammatory cytokines. Chronic exercise is associated with a consistent shift towards a more anti-inflammatory cytokine profile (Transforming Growth Factor-beta, and Interleukin-2 and 13, whereas acute bouts of intense exercise can transiently increase pro-inflammatory cytokine levels. The influence of MT on cytokines was less commonly studied and yielded more variable results. Variability in findings is likely related to the subject and their baseline condition or disease, when measurement occurs, and the exercise intensity, duration, and an individual's overall health and fitness.

Role of nutritional support in nursing practice for improving surgical site wound healing in patients post-surgery with risk of pressure ulcers.

To explore the role of nutritional support in nursing practice on postoperative surgical site wound healing in patients undergoing surgery at risk for pressure ulcers. This study adopted a retrospective experimental design and included a total of 60 patients at risk of pressure ulcers, divided into a nutritional support group and a control group, with 30 people in each group. The nutritional support group implemented specific nutritional support measures after surgery, while the control group received standard postoperative care. Outcome measures included redness and swelling scores, edema scores, anxiety assessments, pain scores, bleeding volume, recovery time and incidence of pressure ulcers. The result indicates that patients who received nutritional support exhibited lower postoperative wound redness and swelling scores compared to the control group (3.11 ± 0.45 vs. 4.85 ± 0.74, p < 0.05). Additionally, the nutritional support group showed significantly lower edema scores (2.75 ± 0.37 vs. 3.53 ± 0.62, p < 0.05). Anxiety levels, as measured by the anxiety assessment scale (SAS), were also lower in the nutritional support group (6.52 ± 1.19 vs. 7.60 ± 1.62, p < 0.05). Moreover, the average healing time was shorter for the nutritional support group (7.27 ± 1.36 days) compared to the control group (9.71 ± 1.84 days, p < 0.05). Postoperative pain scores were lower in the nutritional support group (4.13 ± 0.72 vs. 5.43 ± 0.62, p < 0.05), and patient satisfaction scores were higher (9.42 ± 0.76 vs. 7.25 ± 0.81, p < 0.05). Nutritional support has a positive effect on postoperative wound healing at surgical sites in patients at risk of pressure ulcers in nursing practice. It can significantly reduce redness, swelling, edema, anxiety, and pain scores, reduce bleeding, shorten recovery time, and reduce pressure ulcers. incidence rate.

The efficacy of bandage contact lens in relieving the aggravation of dry eye disease after complicated cataract or/and IOL surgery

PurposeIn the present study, we aimed to evaluate the efficacy of the bandage contact lens (BCLs) in the treatment of dry eye disease (DED) after complicated cataract or/and intraocular lens (IOL) surgery.MethodsIn this retrospective, single-centered, observational study, we collected data from 69 patients who underwent complicated cataract or/and IOL surgery. Of these, 35 cases wore their own BCLs immediately after the operation, while the other 34 cases did not have their own BCLs and were instead covered with gauze. The Ocular Surface Disease Index (OSDI) questionnaire, slit-lamp microscope examination, keratograph analysis, and Schirmer I test were measured at baseline, 1 week and 1 month postoperatively.ResultsIn the BCL group, the score of the OSDI questionnaire was significantly decreased at 1 week and 1 month postoperatively compared with baseline levels (P = 0.000, collectively). Moreover, the fluorescein staining score of the BCL group was remarkably decreased 1-week and 1-month postoperatively compared with the non-BCL group (P = 0.000 and P = 0.000, respectively). Furthermore, the redness score of the BCL group was also better compared with the non-BCL group at 1 week and 1 month postoperatively (P = 0.014 and P = 0.004, respectively).ConclusionsComplicated cataract or/and IOL surgery would intensify the DED. Early application of BCLs postoperatively improved patients’ comfort and alleviated dry eye-related symptoms and signs. Furthermore, this mechanism might involve the acceleration of corneal epithelial healing, the alleviation of ocular stress response and the stabilization of the tear film.Trial registrationTrial registration ClinicalTrials, NCT04120389.

Efficacy of Topical Palmitoylethanolamide (Levagen+) for the Management of Eczema Symptoms: A Double-Blind, Comparator-Controlled, Randomized Clinical Trial

Introduction: Eczema is a debilitating skin disorder clinically characterised by the development of itchy, dry, rough, and scaling skin caused by a series of rudimentary clinical phenotypes. Methods: This double-blind, randomised, comparator-controlled trial evaluated the effectiveness of topical application of a novel palmitoylethanolamide formulation (Levagen+) compared with a standard moisturiser (comparator) to reduce eczema severity and improve patient outcomes. Seventy-two participants aged over 18 years old with atopic eczema (symptoms including redness, dry skin, scaling, and/or itchiness) on their hands or arm were recruited. Participants were randomly allocated to one of two treatment groups (Levagen + or comparator). Treatment was applied to the affected area twice daily for 4 weeks. Outcome measures included Self-Assessed Eczema Area Severity Index (SA-EASI) scoring and Patient-Oriented Eczema Measure (POEM) from baseline to week 4. Results: Levagen+ was effective at alleviating symptom severity of eczema over 4 weeks. Levagen+ significantly reduced redness, dryness, and total POEM score compared to a comparator cream. Conclusion: Levagen+ can significantly reduce eczema symptom severity compared to a comparator product, supporting its use as a potential treatment for eczema.

External validation of a red cell-based blood prognostic score in patients with metastatic renal cell carcinoma treated with first-line immunotherapy combinations

Immunotherapy combinations with tyrosine-kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) had significantly improved outcomes of patients with mRCC. Predictive and prognostic factors are crucial to improve patients’ counseling and management. The present study aimed to externally validate the prognostic value of a previously developed red cell-based score, including hemoglobin (Hb), mean corpuscular volume (MCV) and red cell distribution width (RDW), in patients with mRCC treated with first-line immunotherapy combinations (TKI plus ICI or ICI plus ICI). We performed a sub-analysis of a multicentre retrospective observational study (ARON-1 project) involving patients with mRCC treated with first-line immunotherapy combinations. Uni- and multivariable Cox regression models were used to assess the correlation between the red cell-based score and progression-free survival (PFS), and overall survival (OS). Logistic regression were used to estimate the correlation between the score and the objective response rate (ORR). The prognostic impact of the red cell-based score on PFS and OS was confirmed in the whole population regardless of the immunotherapy combination used [median PFS (mPFS): 17.4 vs 8.2 months, HR 0.66, 95% CI 0.47–0.94; median OS (mOS): 42.0 vs 17.3 months, HR 0.60, 95% CI 0.39–0.92; p < 0.001 for both]. We validated the prognostic significance of the red cell-based score in patients with mRCC treated with first-line immunotherapy combinations. The score is easy to use in daily clinical practice and it might improve patient counselling.

Efficacy and Skin Microbiome Modulation Effects of a Fixed-Concentration Combination of Benzoyl Peroxide 4% Plus Niacinamide 4% in a Film-Forming Cream in Subjects with Mild-to-Moderate Acne: A Non-Sponsored, Prospective, Assessor-Blinded, Pilot Trial

Benzoyl peroxide (BPO) and niacinamide (Niac) are commonly used alone or in combination with other molecules in the treatment of acne. BPO and Niac in the same product could exert complementary and synergistic effects improving efficacy in acne. Furthermore, Niac could reduce some side effects of BPO, such as skin irritation and erythema. A film-forming cream product containing BPO 4% and Niac 4%, vehiculated in a mixture of polyvinyl alcohol (PVA) and perfluoropolyether (PFPE) has been recently developed (B-N cream). A 28-day, assessor-blinded pilot trial was conducted to evaluate the clinical efficacy, skin tolerability, sebum production, skin redness, and skin microbiome modulation of B-N cream in subjects with mild to moderate acne of the face. Twenty-two adult men and women with mild-to-moderate acne of the face participated in this trial, after their written informed consent. B-N cream was applied once daily in the evening. The use of B-N cream was associated with a statistically significant decrease in acne lesions after treatment in comparison with baseline (non-inflammatory lesions: −40%; inflammatory lesions: −43% and total lesions: −41%). The use of the cream was not associated with a skin barrier function alteration. The skin redness score (−11%) and the sebum production (−42%) were significantly reduced after treatment. The use of B-N cream determined a reduction in the relative abundance of the Actinobacteria phylum (Corynebacterium and Propionibacterium, from 56% to 47%) and a significant increase in the abundance of Bacteroidetes phylum (from 3% to 5.2%). In addition, the product was well tolerated. In conclusion, this film-forming, medical device cream was effective in subjects with mild-to-moderate acne, reducing acne lesions and sebum production without altering skin barrier function, offering good skin tolerability. Furthermore, this product exerts positive skin microbiome modulation effects.

Effects of Aqua-acupuncture on Wound Healing in Rainbow Trout

This study investigated the effect of a single aqua-acupuncture (aqua-AP) treatment on wound healing after surgical ventral incision in rainbow trout, Oncorhynchus mykiss. Three experiments were conducted using 20 fish per experiment (10 aqua-AP, 10 non-acupuncture): 1) ventral incision closed with two sutures and insertion of an acoustic transmitter, 2) ventral incision closed with two sutures (no transmitter), and 3) unclosed ventral incision. Aqua-acupuncture was performed by injecting a 0.25 mL bleb of vitamin B12 - saline mixture intramuscularly at 4 points around the surgical site. Statistical differences between aqua-AP and non-acupuncture for survival, transmitter retention, wound closure and redness (inflammation) were conducted (p&lt;0.05). Experiment 1 had significantly lower (p=0.007) redness scores with aqua-AP treatment when compared to non-acupuncture. In the second and third experiments, there were no significant differences in wound closure times or redness, and acoustic transmitter retention was not significantly different between treatments. Experiment 3 had granuloma formation (50% both groups) in place of skin edge closure at 6 weeks. By study termination (12 weeks), only 1 aqua-AP fish still had a granuloma compared to 4 fish in non-acupuncture (p&lt;0.04). There were no significant differences in wound closure times (aqua-AP versus non-acupuncture). While the overall results of this study were inconclusive for wound healing time, the decreased redness (Experiment 1) and improved granuloma resolution (Experiment 3) suggest that there may be potential benefit from aqua-AP use in rainbow trout wound healing. Aqua-AP appears safe to use on fish with future research directed at technique refinement.

Rosacea treatment with mussel adhesive protein delivered via microneedling: Invivo and clinical studies.

Rosacea is a prevalent chronic dermatological condition marked by facial inflammation and erythema, significantly compromising the quality of life for affected individuals. Current treatment methods for rosacea are not considered ideal because of the complex etiology of the disease. Mussel adhesive protein (MAP) is a glycoprotein derived from the foot gland of mussels. The protein exhibits anti-inflammatory properties, relieves skin itching, and promotes wound healing. We aimed to explore the feasibility of using MAP administered via microneedle delivery for treating rosacea and the potential molecular mechanism involved. The therapeutic effect and mechanism of MAP microneedle delivery in an LL-37-induced rosacea-like mouse model were observed using morphological and histological methods. Twenty-seven patients with erythematotelangiectatic rosacea (ETR) underwent treatment once every 1 month, with three treatments constituting one treatment course. The therapeutic effect was evaluated by comparing the clinical images taken at baseline, after the first treatment course, and after the second treatment course. The red value, CEA, and GFSS score were also calculated. In response to the microneedle delivery of MAP, innate immunity, inflammatory infiltration, and abnormal neurovascular regulation improved significantly in rosacea-like mice. In the clinical experiments, the microneedle delivery of MAP significantly improved the symptoms of erythema, flushing, and telangiectasia in patients with ETR, and no obvious adverse reactions were observed. MAP delivered by microneedling is effective and safe for treating ETR.

Colchicine Alleviates Rosacea by Inhibiting Neutrophil Inflammation Activated by the TLR2 Pathway.

Rosacea is a chronic facial inflammatory skin disease that occurs with dysfunction of the immune system. Colchicine was reported to have anti-inflammatory properties. However, the impact of colchicine on rosacea remains unclear. In the present study, the phenotype of rosacea lesions was evaluated by the redness score, inflammatory biomarkers were analyzed by reverse transcription PCR (RT‒PCR), and the infiltration of inflammatory cells was assessed by IHC analysis and immunofluorescence in a rosacea-like mouse model. In vitro, RT‒PCR was used to identify the inflammatory factors that Toll-like receptor 2 (TLR2) agonist caused neutrophils to produce, and immunofluorescence and coimmunoprecipitation were used to identify putative signalling pathways. We found that skin erythema and histopathological alterations, as well as elevated proinflammatory factors (IL-1β, IL-6, TNFα, CXCL2) and CAMP, were significantly ameliorated by colchicine treatment in LL37-induced rosacea-like mice. In addition, colchicine reduced the colocalization of TLR2 and neutrophils and the formation of neutrophil extracellular trap networks (NET) in mouse lesions. In neutrophils, colchicine markedly reduced TLR2 agonist-induced inflammatory biomarker expression, NET formation, and ROS production. Moreover, we found that LL37 could bind to TLR2 upon activation of TLR2 in neutrophils. Importantly, colchicine could repress the combination of TLR2 and LL37 in vivo. Finally, bioinformatics methods further validated the key molecules of neutrophil-related inflammation in rosacea, which is consistent with our experimental findings. Collectively, colchicine ameliorated rosacea-like dermatitis by regulating the neutrophil immune response activated by the TLR2 pathway, indicating that it could be an effective therapeutic option for patients with rosacea.

P436 The AI based Red Density score is correlated with the established and new histological indices for Ulcerative Colitis in an independent cohort

Abstract Background Red Density (RD) is an automated endoscopic tool that is developed for the objective evaluation of disease activity in ulcerative colitis (UC). The initial development integrated histological disease activity based on Robarts histological index (RHI) in the machine learning algorithm. New histological scores for UC have been developed since. The aim of this study was to establish the correlation between RD and the Nancy histological index (NHI) and PICaSSO Histologic Remission Index (PHRI). Methods Patients included in 4 centers in the ongoing PROCEED-UC study (NCT04408703) had assessment with RD in the rectum and sigmoid at baseline, w52 or early termination visit. Biopsies were taken according to protocol. Biopsies were scored for the Geboes score (GBS), RHI, NHI, PHRI in a blinded way after initial scoring convention training. Correlation was tested on patient level between mean RD per segment and the different histological indices based on Spearman correlation. Results In total 96 patients from 4 centers were included representing 2634 RD images from 400 colonic segments with biopsies and corresponding RD score. Mean (± SEM) rectal RD score was 32.7 (± 4.54), 33.69 (± 5.25) and 64.86 (± 31.71) at baseline, w52 and ET respectively. Mean sigmoidal RD score was 38.13 (± 3.68), 42.82 (± 11.80) and 77.33 (± 24.65) at baseline, w52 and ET respectively. Analysis based on the segment with the highest mean RD score per patient showed significant correlation with NHI (r=0.60, p&amp;lt;0.0001), PHRI (r=0.62, p&amp;lt;0.0001). In the rectum the RD score at all time points correlated significant with NHI (r =0,53, p&amp;lt;0.0001) and PHRI (r=0.63, p&amp;lt;0.0001). Similar correlation was seen in the sigmoid for NHI (r=0.51, p&amp;lt;0.0001) and PHRI (r=0.22, p0.0108). A RD score of &amp;lt;57.5 (Likelihood Ratio (LR) 4.176; AUC 0.7820 (95CI 0.7047 - 0.8593), p&amp;lt;0.0001) was associated with histological remission based on NHI (&amp;lt;2) and a RD score of &amp;lt; 64.5 (LR 9.821; AUC 0.8133 (95%CI 0.7053 - 0.9212), p&amp;lt;0.0001) with histological remission based on PHRI (=0). The current dataset demonstrated to be stable in line with the previously established RD cut-off with GBS and RHI. 1 Conclusion In an independent cohort of patients with UC the correlation with the established and new histological indices for UC is confirmed. This underlines the value of RD as an objective endoscopic tool for the assessment of histological and endoscopic disease activity in UC.

The impact of the newly developed school-based 'Digital Health Contact'-Evaluating a health and wellbeing screening tool for adolescents in England.

Supporting adolescents with their health and wellbeing is an international public health priority. Schools are well placed to universally detect unmet health needs and support pupils. This study aimed to evaluate the effectiveness of a digital health and wellbeing screening tool, called the 'Digital Health Contact' (DHC) implemented in schools in the East Midlands of England. The DHC, delivered by Public Health Nurses (School Nurses) (PHN(SN)), aims to identify pupils with unmet health needs (via a 'red flag' system) and provide appropriate support. Using data from 22 schools which took part in the DHC and 14 schools which did not take part, across three academic years (2018-2020), we conducted a controlled interrupted timeseries analysis with negative binomial regression to explore the effect of the DHC on the number of annual referrals to PHN(SN). Using DHC data from 164 pupils, we further conducted a Difference-in-Difference analysis to explore the impact of 'red flag' and referral via the DHC in Year 9 (age 13-14) on the number of red flags in Year 11 (age 15-16). Across all schools, the mean annual number of referrals increased over the three year follow-up period. In the adjusted model, the number of referrals was comparable between schools taking part in the DHC and non-participating schools (0.15 referrals [95% CI -0.21, 0.50]). Red flag score was not significantly different among Year 11 pupils, after being referred via the DHC in Year 9 (-0.36 red flags [95% CI -0.97, 0.24]). The DHC, and similar screening tools, have the potential to raise awareness of the health and wellbeing support in schools and provide an additional pathway of referral to this support for pupils with unmet health needs, without replacing the traditional pathway where pupils refer themselves or are referred by teachers.

Chemical, Microbial, and Sensory Effects of Natural Preservatives as Sulfur Dioxide Replacers in Boerewors

This study determined whether natural preservatives, when used as substitutes for sulfur dioxide (SO2) in Boerewors, influenced water activity (aw), pH, and moisture content; microbial and sensory quality; and the lipid oxidative and color stability in Boerewors models. The inclusion of sulfur dioxide at 0.035% (positive control), formulation without preservatives (negative control); protective cultures (PrC1 and PrC2), containing lactic acid bacteria; and plant extract blends (KD1 and KD2), containing rosemary and acerola extracts and buffered vinegar, were evaluated. The use of KD2 increased pH on Days 0 and 6, but the increased pH did not affect the microbial preservative effect. The aw of the treatments was stable over 6 days and therefore also did not have an influence on the microbial preservative effect of the natural preservatives. Both plant extract preservatives (KD1 and KD2) increased the oxidative stability of lipids more than any other treatment, including the positive control. The microbial stability results were inconclusive because of the protective cultures, which increased the total bacteria count. The counts of coliform and Enterobacteriaceae, Escherichia coli, and Staphylococcus aureus were analyzed, but significant differences between the treatments were not observed. KD1, which contained rosemary plant extract, maintained the lowest TBC at the same level as the positive control but had a slightly lower redness score. Treatments had no effect on sensory evaluation. The use of KD1 and KD2 plant preservatives proofed to be worthy as replacers of SO2 in Boerewors. This manuscript contains research data that formed part of an M.Sc. thesis. This manuscript also contains materials and methods that were used in a Ph.D. thesis where salt reduction in South African meat products was evaluated.

Global patterns of plumage color evolution in island-living passeriform birds

Island environments have the potential to change evolutionary trajectories of morphological traits in species relative to their mainland counterparts due to habitat and resource differences, or by reductions in the intensity of social or sexual selection. Latitude, island size, and isolation may further influence trait evolution through biases in colonization rates. We used a global dataset of passerine plumage color as a model group to identify selective pressures driving morphological evolution of island animals using phylogenetically-controlled analyses. We calculated chromaticity values from red and blue scores extracted from images of the majority of Passeriformes and tested these against the factors hypothesized to influence color evolution. In contrast to predictions based on sexual and social selection theory, we found consistent changes in island female color (lower red and higher blue chromaticity), but no change in males. Instead, island size and distance from mainland and other islands influenced color in both sexes, reinforcing the importance of island physiognomy in shaping evolutionary processes. Interactions between ecological factors and latitude also consistently influenced color for both sexes, supporting a latitudinal gradient hypothesis. Finally, patterns of color evolution varied among families, indicating taxon-specific microevolutionary processes in driving color evolution. Our results show island residency influences color evolution differently between sexes, but the patterns in both sexes are tempered by ecological, island characteristics, and phylogenetic effects that further vary in their importance among families. The key role of environmental factors in shaping bird plumage on islands further suggests a reduced importance of sexual and social factors in driving color evolution.

Topical Application of Acerola Cherry Powder in Combination With Rosemary Extract Extends the Shelf Life of Beef Chuck Roll and Bone-In Short Rib Steaks

Improving the shelf life of steaks from beef chuck rolls and bone-in short ribs, items commonly exported, will increase the demand of beef in international markets. Our objectives were to determine the effect of topically applying combinations of acerola cherry powder and rosemary extract on steak color and lipid oxidation of beef chuck roll and bone-in short rib. USDA Choice beef chuck rolls (Institutional Meat Purchase Specifications [IMPS] 116A; N=9) andbone-in short ribs (IMPS 123A; N=18) were aged (0°C) 28 d and cut into 1.0 cm-thick steaks. Steak treatments included the following: untreated control (C) or topically sprayed (2 mL) with an acerola cherry powder solution (0.05% A), rosemary extract solution (0.10% R), or mixture of acerola cherry powder and rosemary extract (M1=0.05% A+0.1% R; M2=0.1% A+0.1% R; M3=0.05% A+0.2% R; M4=0.1% A+0.2% R). On day 0 of retail display, oxygen consumption, metmyoglobin-reducing activity, and lipid oxidation were measured. Lipid oxidation was evaluated again following 4 d of retail display. Chuck roll steak color was scored twice daily, whereas short rib lean and bone marrow color were scored once daily throughout 4 d of retail display. Treating chuck roll steaks with M2, M3, and M4 decreased lipid oxidation compared to C and A (P=0.004). In short rib steaks, lipid oxidation remained constant from day 0 to 4 treated with M4 but increased for all other treatments (P&amp;lt;0.001). Chuck roll steaks treated with A, M2, and M3 were redder than C steaks (P=0.001). On days 0 and 4, untreated bone marrow was less red than all the antioxidant treated bone marrow (P=0.011). Antioxidant treatment did not improve subjective lean color for the chuck roll (P=0.324) or bone-in short rib (P=0.081). Topical application of M4 (0.1% acerola cherry powder and 0.2% rosemary extract) reduced lipid oxidation in both chuck roll and bone-in short rib steaks. Additionally, antioxidants alone or in combination with one another improve objective redness scores by up to 2 points; however, the subjective color panel did not observe lean color improvement.

Effects of Diquafosol Sodium Ophthalmic Solution on Tear Film Matrix Metallopeptidase-9 and Corneal Nerve Density in Patients with Type 2 Diabetic Dry Eye.

Purpose: Diabetes mellitus has been associated with increased dry eye disease (DED) and exacerbates DED's pathology. This preliminary short-term study aimed to evaluate the effects of 3% Diquafosol Sodium ophthalmic solution (DQS) on ocular surface inflammation and corneal nerve density in diabetic dry eye (DDE) patients. Methods: In this perspective, participants used 1 drop of 3% DQS (Diquas; Santen Pharmaceutical Co., Ltd., Osaka, Japan) 6 times daily for 8 weeks. Non-invasive tear breakup time (NITBUT), tear film lipid layer (TFLL), conjunctival hyperemia [redness score (RS)], corneoconjunctival staining (CFS), corneal sensitivity (CS), Meibomian gland quality (MGQ) and Meibomian gland expressibility (MGEx), corneal nerve fiber density (CNFD), and Standard Patient Evaluation Eye Dryness (SPEED) questionnaire were assessed at baseline, at weeks 4, and up to 8 weeks. Matrix metalloproteinase-9 (MMP-9) of tear samples was measured at baseline and weeks 8. Results: The mean age was 61.27 ± 11.68 years. At baseline NITBUT = 5.89 ± 2.81 s, tear meniscus height = 0.17 ± 0.05 mm, TFLL = 2.74 ± 0.51, CFS = 4.35 ± 0.68, CS = 53.83 ± 9.63 mm, MMP-9 = 49.10 ± 10.42 ng/mL, RS = 1.65 ± 0.44, MGEx = 1.85 ± 0.72, MGQ = 2.65 ± 0.50, CNFD = 20.36 ± 8.20 no./mm2, and SPEED = 12.62 ± 3.91. At week 4, significant improvements were found in all parameters except RS (1.59 ± 0.46, P = 0.172) and CNFD (21.46 ± 8.41, P = 0.163). Finally, at week 8, all parameters had significant improvements. Conclusion: Preliminary short-term findings suggest that treatment of DDE patients with DQS was found to be safe and efficacious in improving dry eye parameters. In addition, inflammatory marker and corneal nerve density were significantly improved. This study was registered with ClinicalTrials.gov (NCT05193331).

Pengaruh metode akupuntur terhadap penurunan kekeringan dan kemerahan kulit pada pasien xerosis

Background: Xerosis, or dehydrated skin, significantly impacts comfort. Severely dry skin can cause severe itching, irritation, and physical discomfort. It can disrupt sleep, concentration, and daily performance of individuals. Although several studies have evaluated the impact of acupuncture on skin health, strong scientific evidence regarding its effectiveness in treating xerosis is still limited.Objectives: This study aimed to evaluate the influence of acupuncture on reducing skin dryness and redness in patients with xerosis.Methods: This research collected data from 30 patients with xerosis who underwent acupuncture sessions. Skin dryness and redness scores were measured before and after the acupuncture session. The collected data were then analyzed using descriptive statistics and paired samples t-tests.Results: The results of the study showed that acupuncture significantly influenced reducing skin dryness scores by 7,36% and skin redness scores by 15,2% in patients with xerosis after the acupuncture session. This indicates that acupuncture effectively addresses the symptoms of xerosis by reducing skin dryness and redness. This research provides evidence supporting the use of acupuncture as an effective alternative therapy in managing xerosis and improving the quality of life for patients.Conclusion: In this study, acupuncture has been proven to reduce skin dryness and redness in patients with xerosis significantly. These findings suggest that acupuncture can be an effective therapeutic option in addressing the symptoms of xerosis, such as skin dryness and redness. The use of acupuncture as a non-invasive and safe alternative therapy can enhance the quality of life for patients experiencing xerosis.

Comparison of Phaco-Tanito Microhook Trabeculotomy between Propensity-Score-Matched 120-Degree and 240-Degree Incision Groups

This study compared the effectiveness and safety of 120-degree (nasal) and 240-degree (bilateral) incisions in Tanito Microhook Trabeculotomy (TMH) combined with cataract surgery in patients with open-angle glaucoma. From a pool of 185 eyes, 67 eyes from 67 subjects were selected for each incision group using propensity score matching to align age, sex, glaucoma type, and preoperative intraocular pressure (IOP). The study found that preoperative IOP, initially 18.6 mmHg in both groups, decreased to 13.2 mmHg in the nasal group and 12.8 mmHg in the bilateral group 12 months postoperatively, representing reductions of 29% and 31%, respectively. Similarly, medication scores decreased from 3.4 to 2.7 in the nasal group and from 3.1 to 2.5 in the bilateral group. Notably, the bilateral incision group exhibited a significantly higher hyphema red blood cell score compared to the nasal group (p &lt; 0.0001). Across the study period, other parameters such as IOP, medication score, visual acuity, anterior chamber flare, corneal endothelial cell density, visual field mean deviation, and the frequency of surgical complications other than hyphema were similar between the groups. The study concluded that TMH combined with cataract surgery is equally effective and safe regardless of incision width, although narrower incisions resulted in reduced early postoperative hyphema.
