Assessing Skin Tear Knowledge Among Nurses: A Multicentre Cross-Sectional Survey.

AIMS: To assess the knowledge of nurses in Chinese hospitals regarding skin tears, focusing on evaluating their understanding and proficiency in managing and preventing skin tears, exploring the impact of demographic and professional factors on their knowledge levels and identifying specific areas where additional training or education is needed. DESIGN: This study is a multicentre cross-sectional survey conducted in the Henan province of China using a stratified cluster sampling method. METHODS: The study utilised the Chinese version of the Skin Tear Knowledge Assessment Instrument (OASES) for evaluating nurses' knowledge levels based on a questionnaire comprising 22 questions on the online platform Wenjuanxing (www.wjx.cn). All questions had to be answered, with only one option selectable per question. Response validity was ensured by excluding questionnaires that showed a clear response pattern, were completed in under 60 s, or scored 0 points. Descriptive analysis, item-level analysis and multiple linear regression analysis were performed. RESULTS: A total of 1675 clinical nurses participated in this study. Age was a significant factor influencing skin tear knowledge, with older nurses (age, 41-60 vs. 18-40 years) demonstrating higher knowledge scores. Additionally, female nurses exhibited higher average knowledge scores compared to male nurses. Further, different departments, education levels, job titles and having completed relevant courses significantly influenced skin tear knowledge among nurses. However, on multivariate analyses, we found that working in the intensive care unit, having a higher education background and job title and having studied courses on wound, ostomy or incontinence were independent factors influencing knowledge on skin tear, indicating the need for targeted educational interventions. CONCLUSION: In conclusion, targeted educational interventions and continuous professional development are essential to bridge the identified knowledge gaps among nurses in Chinese hospitals regarding skin tear management. REPORTING METHOD: The Strengthening the Report of Observational Studies in Epidemiology checklist guidelines were followed. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Enhancing nurses' knowledge and skills in skin tear management through targeted educational programmes could improve patient care quality, reduce the incidence of skin tears and promote better wound care outcomes in clinical settings. IMPACT: This study addresses the problem of knowledge gaps in skin tear management among nurses. The main findings indicate varied understanding and significant factors influencing this knowledge. The research impacts nurses and patients in Chinese hospitals, emphasising the need for specialised training and professional development to improve skin tear management and patient care. No patient or public contribution.

Longitudinal Analysis of Tear Cytokine Ratios in Association with Dry Eye Signs and Symptoms in the Dry Eye Assessment and Management (DREAM) Study.

PURPOSE: To extend cross-sectional data on cytokine ratios (CRs) in dry eye disease (DED) signs by investigating longitudinal change in pro- to anti-inflammatory CRs and associations with change in DED signs and symptoms. METHODS: Secondary analysis of fifty-four subjects [mean age 57.3 (SD 13.2) years, 85.2% female; 68.5% white] with ≥ 4 uL pooled tear volumes at months 0, 6, and 12. Pro-inflammatory (IL-1b, IL-6, IL-8, IL-17A, IFN-g, and TNF-a) to anti-inflammatory (IL-6, IL-10) cytokine ratios (CR) were calculated. DED signs (corneal and conjunctival staining scores, tear break-up time, Schirmer test, Meibomian gland plugging, tear osmolarity, composite sign severity score) and symptoms [Ocular Surface Disease Index (OSDI)] were measured. Changes over time in DED signs, symptoms, and CRs were evaluated using longitudinal models. Correlations between changes in CR and changes in DED signs and symptoms were evaluated using Spearman correlation coefficients (rho). RESULTS: DED signs which improved over time (p < 0.001) included corneal and conjunctival staining score, tear break-up time, tear osmolarity, and composite sign severity score. Using IL-10 as anti-inflammatory, changes in corneal and conjunctival staining and composite severity score significantly correlated with changes in pro- to anti-inflammatory CRs from month 0 to 6 (|rho|: 0.29-0.45, p: 0.003-0.04) but not between month 0 to 12 (|rho|: 0.01 to 0.24, all p > 0.08). DED symptoms decreased across one year (p < = 0.001) for all OSDI measures; these changes did not correlate with changes in CRs (|rho|: 0.00 to 0.29, all p > 0.04). CONCLUSIONS: Improvement in some DED signs across one year correlated weakly with decreases in pro- to anti-inflammatory CRs, in alignment with the understanding of DED as inflammatory. CRs may provide greater insight than absolute tear cytokine concentrations as possible DED biomarkers. Additional studies that provide standardized clinical information and tear collection and analysis are needed to validate CRs in DED.

Arthroscopic Assessment of the Incidence of Biceps Pulley Lesions Associated With Rotator Cuff Tears: An Observational Study.

The shoulder joint houses a stabilizing structure called the biceps pulley. Biceps pulley lesions can trigger anterior shoulder pain and frequently coincide with rotator cuff tears, whose prevalence rises with age. In our study, we aim to assess the incidence of biceps pulley lesions associated with rotator cuff tears in patients undergoing arthroscopic repair, the possible associated factors, and whether MRI findings were correlated with them. This study was a prospective observational one conducted at Al-Hadra University Hospital. The patients aged 40 to 65 years were indicated for arthroscopic repair of a rotator cuff tear. We used IBM Corp. Released 2011. IBM SPSS Statistics for Windows, Version 20.0. Armonk, NY: IBM Corp. to conduct the analysis. A total of 60 patients were enrolled in the study. The mean age was 50.97 ± 6.90. The overall incidence of biceps pulley lesions was 85%. Older age was found to be significantly associated with increased incidence. On the other hand, gender, and the mode of injury (cuff tear) had no significant associations with the incidence. Also, formal MR had no significance in diagnosing biceps pulley lesions. The overall incidence of biceps pulley lesions in the current study was 85%. The older the patient with a cuff tear, the greater the incidence of finding a pulley lesion arthroscopically. Moreover, MRI did not have a significant role in diagnosing the biceps pulley lesions.

The Trillat procedure: the man and the technique revisited through the lens of arthroscopy.

The Trillat procedure, initially described by Albert Trillat, is historically one of the first techniques for addressing recurrent anterior shoulder instability, incorporating fascinating biomechanical mechanisms. After lowering, medializing, and fixing the coracoid process to the glenoid neck, the subcoracoid space is reduced, the subscapularis lowered, and its line of pull changed, accentuating the function of the subscapularis as a humeral head depressor centering the glenohumeral joint. Furthermore, the conjoint tendon creates a 'seatbelt' effect, preventing anteroinferior humeral head dislocation. Even though contemporary preferences lean towards arthroscopic Bankart repair with optional remplissage, bone augmentation, and the Latarjet procedure, enduring surgical indications remain valid for the Trillat procedure, which offers joint preservation and superior outcomes in two distinct scenarios: (i) older patients with massive irreparable cuff tears and anterior recurrent instability with an intact subscapularis tendon regardless of the extent of glenoid bone loss; (ii) younger patients with instability associated shoulder joint capsule hyperlaxity without concomitant injuries (glenoid bone loss, large Hill-Sachs lesion). Complications associated with the Trillat procedure include recurrent anterior instability, potential overtightening of the coracoid, leading to pain and a significant reduction in range of motion, risk of subcoracoid impingement, and restriction of external rotation by up to 10°, a limitation that is generally well-tolerated. The Trillat procedure may be an effective alternative technique for specific indications and should remain part of the surgical armamentarium for addressing anterior shoulder instability.

Recurrent ganglion cyst in the anterolateral portal following knee arthroscopy.

Ganglion cysts (GC) are an uncommon complication following arthroscopic knee surgery. Due to high rates of recurrence following GC resection, many symptomatic patients can experience pain and discomfort for years. The presence of a GC at the site of an arthroscopic knee portal has only been reported once before in the literature. This case report details the history, physical and treatment of an active-duty soldier who had undergone various aspirations and surgical resections with limited improvement until the most recent operative intervention. At 18 months postoperatively, the patient had not experienced recurrence and had returned to all activities. We believe this surgical technique yielded resolution of the GC because following resection, the joint was checked to exclude areas of fluid extravasation, the capsule closure was performed with non-absorbable barbed suture and the operative extremity was immobilised in extension for 2 weeks to promote soft tissue rest and healing.

Overview of 37 Tear Substitutes in Europe Based on Various Physicochemical Parameters.

INTRODUCTION: Dry eye disease (DED) is one of the most prevalent eye conditions worldwide, with artificial tears serving as a primary treatment option. Despite their wide availability on the European market, there is a lack of established classifications based on their physicochemical properties. The aim of our study was therefore (i) to develop an analytical method that measures the concentration and the molecular weight (MW) of the hyaluronic acid (HA) in commercialized products, and (ii) to propose an overview based on their various physicochemical parameters. METHODS: The intrinsic viscosity and MW of the HA, as well as osmolarity, pH, rheological profile, and viscosity, were measured or determined. A specific method was developed to measure the average intrinsic viscosity and HA content using a liquid size-exclusion chromatography system. The MW was determined using the Mark-Houwink equation. RESULTS: Thirty-seven products commercialized in Europe were analyzed, with 21 of them containing HA. The HA MW was lowest (300 kDa) for Thealose®, Thealoz Duo® Gel, and Hyabak®, and highest (1300 kDa) for Vismed® Multi, Vismed® Gel, and Neovis® Gel. The pH values varied between 5.94 for Treovis® and 8.06 for Systane® Ultra. Osmolarity ranged between 148 mOsm/L and 325 mOsm/L for Neovis® and Treovis®, respectively. Viscosity was highly variable, ranging from 0.38 mPas·s for Hylolipid® to 337.47 mPas·s for Thealoz® Duo Gel. Finally, rheological profile analysis revealed different shear-thinning behaviors. CONCLUSION: While the perfect eye drop does not exist, a multitude of options are available to choose from. This study improves our understanding of the major tear substitutes available on the European market based on several physicochemical properties. A better understanding and awareness of these parameters is crucial in order to offer the best treatment for patients with DED.

Comparison of the efficacy and safety of lacrimal gland botulinum toxin injection in functional versus non-functional epiphora.

OBJECTIVE: To determine whether botulinum toxin is effective and safe for the treatment of epiphora, and to compare its utility in functional versus non-functional epiphora using both qualitative and quantitative methods. MATERIALS AND METHODS: Patients were divided into two groups (functional and non-functional epiphora) according to the presence of lacrimal drainage obstruction. All patients were injected with 2.5 units of botulinum toxin into the palpebral lobe of the lacrimal gland, and improvement in epiphora and quality of life were assessed both objectively and subjectively using Schirmer's I test, indoor and outdoor Munk scores, TEARS score, watery eye quality of life score, and tear meniscus measurements at pre-injection, and 1, 3, and 6 months post-injection. Functional and non-functional epiphora groups were compared. RESULTS: Botulinum toxin was injected into 72 lacrimal glands of 65 patients with functional and non-functional epiphora. In both the functional and non-functional epiphora groups, the mean Schirmer's I test value, indoor and outdoor Munk scores, TEARS score, watery eye quality of life score, tear meniscus height, depth, and area values improved significantly at 1, 3, and 6 months after injection compared with pre-injection values (p < 0.05). There were statistically significant differences in mean Schirmer's I test, tear meniscus height, depth, and area values between the functional and non-functional epiphora groups at 1, 3, and 6 months after botulinum toxin injection (p < 0.05). In the functional epiphora group, a greater proportion of patients reported improvement than in the non-functional group. All complications were minor and resolved within 2 weeks after the injection. CONCLUSION: Botulinum toxin injection into the lacrimal glands of patients with functional and non-functional epiphora was a simple, effective, and safe treatment. In addition to qualitative methods, quantitative methods, such as tear meniscus measurement, provided direct evidence that symptomatic improvement occurred more in those with functional versus non-functional epiphora after botulinum toxin injection.

Rotator cuff repair with all-suture anchor enhances biomechanical properties and tendon-bone integration in a rabbit model.

Background: All-suture anchor (ASA) is a special type of suture anchor. It has been used to repair rotator cuff tears (RCTs). However, mechanical properties and tendon-bone integration at different time postoperatively remains to be unclear. Methods: Mechanical testing and water contact angle measurements were conducted for ASA. In vitro biocompatibility was assessed using rat bone marrow stem cells (BMSCs), including live/dead cell staining and Cell Counting Kit-8 assays. ASA was implanted for rotator cuff repair (ASA group) in a New Zealand White rabbit model of RCTs, and a natural rotator cuff was used as a control (natural group). The animals were sacrificed, and tissue samples were harvested for biomechanical, radiographic, and histological analysis at 4, 8, and 12 weeks postoperatively. Results: ASA was hydrophobic and had a strong mechanical property in vitro. The biocompatibility analysis showed that ASA had no effect on the viability of BMSCs. Mechanical testing in vivo revealed that a gradually improved failure load of ASA group was 118.0 ± 22.53N at 12 weeks postoperatively, which was recovered to the natural group. Micro-CT analysis indicated that an initial decrease in BMD and trabecular quality following ASA implantation, with a slight recovery observed at 12 weeks. Additionally, histological analysis showed the tendon-bone interface gradually integrated in the ASA group. A significant increase in tendon-bone interface scores was found from 4 weeks to 12 weeks. Tendon maturing score also improved in the ASA group, and Type I collagen content recovered to 18.58 ± 4.378 % at 12 weeks and no different from that of the natural group. Conclusion: Rotator cuff repair with ASA in a rabbit model demonstrated the capacity to enhance biomechanical properties and tendon-bone integration.

A systematic review of the outcomes of partial ulnar collateral ligament tears of the elbow in athletes treated non-operatively with platelet-rich plasma injection.

Background: This study aimed to analyze the effects of platelet-rich plasma (PRP) for partial ulnar collateral ligament (UCL) tears in athletes and predicted positive outcomes. Methods: The researchers systematically reviewed the PubMed, Cochrane CENTRAL, MEDLINE, Scopus, and Google Scholar databases to identify studies with clinical outcomes of PRP for partial UCL tears. They excluded studies that did not stratify data by tear type or included surgical management. Results: Five studies with 156 patients were included. The timing, amount, platelet concentration, type, and number of PRP injections were highly variable among the studies. However, 75% (n = 97/127) of athletes returned to sport (RTS) at a weighted average of 82.1 days (37-84) after PRP injection. One study showed significant improvements in patient-reported outcomes. Two studies showed positive outcomes in the modified Conway scale, complete reconstitution of the UCL in 87% of patients on MRI, and significant improvement in the humeral-ulnar joint space after PRP injection via ultrasound. The Coleman methodology score (CMS) averaged 48/100, indicating an overall poor quality of evidence. Conclusion: This review demonstrates favorable RTS, clinical, and radiographic outcomes in patients receiving PRP for partial UCL tears, but the literature remains heterogeneous and of low quality. Level of Evidence: III.

Prevalence of Articular Surface Injuries in Patients Undergoing Meniscal Surgery: A Retrospective Analysis of 758 Cases.

Background and aim Meniscal tears are often associated with articular surface damage, which could be an important factor in the clinical outcome. However, these concomitant lesions are usually reported as binary variables. Reports of the severity/extent of the concomitant lesions and stratification by meniscal tear are scarce in the literature; in addition, sample sizes of previous reports are limited. This study aimed to characterize meniscal lesions, determine the prevalence of articular surface lesions and their severity, and correlate these lesions with meniscal injury characteristics. Methods A cross-sectional study of patients undergoing meniscal surgery between 2017 and 2023 was conducted. Patient characteristics and arthroscopic findings on the location and type of meniscal injury as well as the degree of chondral lesion (sICRS score) were recorded by the surgeon. Statistical analysis included frequency reporting for patient characteristics and study variables, including the median and interquartile range of the sICRS classification of articular surface lesions. Meniscal tear types were categorized as degenerative or non-degenerative to explore associations with chondral injury. Chi-square test and univariate and multivariate logistic regression models were employed to analyze relationships between variables. Results A total of 758 surgeries were analyzed, with a mean age of 39.56 years (SD: 12.71) and 67.90% male participants. Medial meniscus injuries accounted for 57.52%, lateral meniscus 36.02%, and both menisci 6.64%. Significant differences were found in vascular area, topography, and lesion type between isolated medial and lateral meniscus lesions (p<0.01). Chondral lesions were present in 35.22% of cases, with significant differences among meniscal injury types (p<0.01). Degenerative tears showed higher rates of chondral damage compared to non-degenerative tears, particularly in lateral meniscus injuries (p<0.01). Regression analysis identified age, gender, meniscal injury characteristics, and meniscectomy percentage as risk factors for articular surface injuries. Conclusion Articular surface injuries frequently accompany meniscal lesions, with associations between affected menisci and articular damage extent. Femoral condyles show greater involvement corresponding to compartment-specific meniscal lesions, unlike tibial plateaus. Meniscal degeneration is present in about half of articular cartilage injury cases. Some meniscal tear types may relate to more severe articular lesions, but larger studies are needed to confirm these findings and explore other tear patterns.

Review of Hydroxypropyl Methylcellulose in Artificial Tears for the Treatment of Dry Eye Disease.

Dry eye disease (DED) is a highly prevalent condition, resulting in reduced quality of life, lower participation in social life and impaired work efficiency. Hydroxypropyl methylcellulose (HPMC) is a cellulose-based viscosity-enhancing agent and is one of the most popular therapeutic ingredients in artificial tears. This review aims to evaluate the literature on the efficacy and safety of HPMC used in the treatment of DED. Literature searches were conducted in PubMed and Cochrane CENTRAL. A total of 28 clinical trials from 26 publications are included in this review, including 21 clinical intervention studies evaluating the effect of HPMC treatment over time and seven single instillation studies evaluating the short-term physical and symptomatic effects of HPMC after drop-instillation. The duration of clinical intervention studies ranged from 2 weeks to 5.5 months. DED severity ranged from mild to severe. Drop frequency ranged from two to up to 16 drops per day. HPMC concentration in artificial tears ranged from 0.2% to 0.5%. No major complications or adverse events were reported. Artificial tears containing HPMC were effective at improving symptoms and some signs of DED. However, combination drops with HPMC plus other therapeutic ingredients seem more effective than HPMC alone. HPMC appears to be equally effective or inferior to hyaluronic acid (HA). There is no evidence of superiority or inferiority to either carboxymethylcellulose (CMC) or polyethylene glycol 400/propylene glycol (PEG/PG). No single study explained the choice of drop frequency or HPMC concentration. More well-designed studies are needed to determine an evidence-based standard for HPMC treatment, including drop frequency, concentration and molecular weight for different DED severity and subgroups.

Comparison of Knotless Versus Knot-Tying Suture Anchors for Arthroscopic Repair of Hip Labral Tears.

Background: Both knotless and knot-tying anchors are commonly employed in the arthroscopic repair of hip labral tears. Purpose: To compare the midterm clinical results of arthroscopic hip labral repair using knot-tying versus knotless suture anchors. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent arthroscopic hip labral repair between January 2017 and January 2021 and who had at least 2 years of follow-up were included. The patients were divided into 2 groups based on the suture anchor type: a 2.9-mm knotless suture anchor (knotless group) or a 1.8-mm knot-tying suture anchor (knot-tying group). All patients underwent femoroplasty for cam lesions and acetabular rim trimming for pincer lesions. The modified Harris Hip Score (mHHS), Hip Outcome Score-Sport-Specific Subscale (HOS-SSS), Hip Outcome Score-Activities of Daily Living (HOS-ADL), 12-item International Hip Outcome Tool (iHOT-12), and visual analog scale (VAS) for pain were administered both preoperatively and postoperatively. The consistency of the outcome scores was assessed using the minimal clinically important difference and Patient Acceptable Symptom State. The statistical significance between groups was evaluated using the Mann-Whitney test and quantile-based analysis of variance. Results: A total of 413 patients were included: 256 patients in the knotless group (median age, 35 years [interquartile range, 31-38 years]; median follow-up, 34 months) and 157 patients in the knot-tying group (median age, 34 years [interquartile range, 30-38 years]; median follow-up, 25 months). There were no significant differences in postoperative mHHS, HOS-ADL, or iHOT-12 scores between the 2 groups. However, there were significant differences, favoring the knotless group over the knot-tying group, in postoperative HOS-SSS (87 ± 2 vs 86 ± 1, respectively) and VAS pain (1 vs 2, respectively) scores (P < .0001 for both). Postoperative synovitis was found in significantly more patients in the knot-tying group than in the knotless group (17 vs 5, respectively; P = .01). Conclusion: In this study, patients who underwent arthroscopic hip labral repair with knotless suture anchors had slightly better postoperative HOS-SSS and VAS pain scores and a lower incidence of postoperative synovitis compared with patients who underwent repair with knot-tying suture anchors.

High-resolution Ultrasound of the Foot and Ankle.

High-resolution ultrasound (US) can be used to assess soft tissue abnormalities in the foot and ankle. Compared to MRI, it has lower cost, is widely available, allows portability and dynamic assessment. US is an excellent method to evaluate foot and ankle tendon injuries, ligament tears, plantar fascia, peripheral nerves, and the different causes of metatarsalgia.

The bioinductive collagen implant yields positive histological, clinical and MRI outcomes in the management of rotator cuff tears: A systematic review.

PURPOSE: The aim of this study is to report and discuss the outcomes of clinical, histological and animal studies exploring the application of bio-inductive collagen implants (BCIs) to partial and full-thickness rotator cuff tears (PT- and FT-RCTs) in addition to reporting on cost-related factors. METHODS: Review of literature was performed using the PRISMA guidelines. A systematic electronic literature search was conducted using the CENTRAL, CINAHL, Cochrane Library, EBSCOhost, EMBASE and Google Scholar bibliographic databases. Microsoft Excel was used to create tables onto which extracted data were recorded. Tables were organized based on the research statement formulated using the PICO approach. No statistical analysis was performed. RESULTS: Nine studies evaluated clinical and MRI outcomes of BCI augmentation for FT-RCTs, seven evaluated similar outcomes when applied to PT-RCTs, two additional studies were case reports and three studies assessed application to FT- and PT-RCTs without stratification of results, one of which also reported on histological data. Two studies reported on histological data alone, and finally, two reported on healthcare costs. BCI augmentation, alone and combined with rotator cuff repair (RCR), displays generally good histological, postoperative clinical and MRI outcomes for PT- and FT-RCT treatment. Recent economic analyses seem to be in favour of the use of this procedure, when selected and applied for appropriate patient populations. CONCLUSION: Several studies have shown promising results of BCI application to PT- and FT-RCTs, both concomitantly and independently from RCR. Investigations report promising histological characteristics, improved clinical outcomes, increased tendon thickness, reduced defect size and lower re-tear rates. LEVEL OF EVIDENCE: Level IV.

The relationship between the shape of rotator cuff tears and shoulder anatomical parameters.

BACKGROUND: The aim of this study is to investigate the potential relationship between shoulder anatomical parameters and the shape of rotator cuff tears (L-shaped, U-shaped, and crescent-shaped). MATERIALS AND METHODS: The study included 160 (n:160) patients. Patients were divided into four groups: crescent type, u type and L type tears and control group. There were 40 cases in each group. The operated patients were divided into three groups based on the shape of the tears in arthroscopic images. Measurements of Critical Shoulder Angle (CSA), Greater Tuberosity Angle (GTA), Acromion Index (AI), Lateral Acromion Angle (LAA), and Humerus Footprint width (coronal width and sagittal width) were taken in each group and compared. RESULTS: Patients were divided into four different groups: Crescent type group (n:40), L type group (n:40), U type group (n:40) and control group (n:40). Upon assessing the coronal and sagittal width measurements, The mean coranal width measurement of the L-type tear group was 12.62 ± 0.29 mm, which was significantly higher than all other groups (p < 0.05). The mean sagittal width of the L-type tear group was 34.95 ± 0.29 mm, which was significantly higher than all other groups (p < 0.05). When the groups were evaluated based on GTA, CSA, and AI data, the mean GTA measurement of the L-type tear group was 73.03 ± 0.95 degrees, which was significantly higher than all other groups (p < 0.05). The mean CSA measurement of the L-type tear group was 34.77 ± 0.66 degrees, which was significantly higher than all other groups (p < 0.05). The mean AI measurement of the L-type tear group was 0.77 ± 0.02, which was significantly higher than all other groups (p < 0.05). When the groups were evaluated based on LAA data, the mean LAA measurement of the L-type tear group was 76.98 ± 1.04 degrees, which was significantly lower than all other groups (p < 0.05). CONCLUSION: In our study, especially in L-shaped tears, measurements of GTA, CSA, AI, LAA, coronal and sagittal width were found to be different compared to the control group. These results suggest that shoulder anatomy affects the mechanisms of rotator cuff tear formation and that these parameters play a more significant role in L-shaped tears.

Exploring novel pharmacological trends: Natural compounds in dry eye disease management.

Dry eye disease (DED) is an ocular condition characterized by altered tear film homeostasis, resulting in symptoms like tear film instability, hyperosmolarity, inflammation, and neurosensory abnormalities. It affects visual acuity and quality of life and is influenced by age, gender, and environmental factors. The first line of treatment consists of dynamically developing artificial tears, gels, and eyelid sprays, which can be supplemented with natural ingredients for enhanced efficacy. Other therapeutic steps include auto-logous serum tears, anti-inflammatory and immunosuppressive eyedrops, or oral tablets. Management also targets Meibomian gland dysfunction and the ocular surface micro-biome. This article explores various therapeutic approaches, including natural compounds and complementary strategies. Natural compounds, such as vitamins, and herbal substances (e.g., trehalose), offer promising benefits in enhancing tear film stability and ocular surface protection. Apitherapeutic products like manuka honey and propolis exhibit antibacterial and anti-inflammatory properties. Additionally, human tissue-derived solutions, such as auto-logous serum tears and amniotic membrane extracts, hold the potential for ocular surface regeneration. Other strategies, including polyherbal eye drops, liposomal eyelid sprays, and microbiome-supporting solutions offer alternative therapeutic avenues. Moreover, patient education, lifestyle modifications, and interdisciplinary collaboration play crucial roles in DED management, emphasizing the importance of holistic care approaches.

Obstetric Perineal Tears, Birth Characteristics and the Association with Urinary Incontinence Among Primiparous Women 12 Months Postpartum: A Prospective Cohort Study.

INTRODUCTION AND HYPOTHESIS: Postpartum urinary incontinence (UI) is common and a concern for many women, as UI leads to a lower quality of life and self-esteem. Perineal tears may be a risk factor for UI, yet few studies have investigated the association between the degree of perineal tear and risk of developing UI postpartum. The objective was to examine how the degree of perineal tear and selected obstetric risk factors were associated with any UI and stress ultrasound (SUI) 12 months postpartum among primiparous women. METHODS: A prospective cohort study was conducted at four Danish hospitals. Baseline data were obtained at a clinical examination 2 weeks postpartum. Symptoms of UI were evaluated 12 months postpartum by the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form questionnaire (web-based). Multivariate regression analyses were performed to investigate the risk factors for UI. RESULTS: A total of 603 primiparous women (203 with none/labia/first-degree tears, 200 with second-degree tears and 200 with third-/fourth-degree tears) were included between July 2015 and January 2018. Women with tears involving the perineal muscles reported any UI more often than women with no/labia or first-degree tears (spontaneous second-degree tear: RR 2.04, 95% CI 0.92-4.50; episiotomy: RR 2.22, 95% CI 0.99-4.96; third- or fourth-degree tear: RR 2.73, 95% CI 1.18-6.28). The same was found for SUI, but with wider confidence intervals. CONCLUSIONS: A higher prevalence of any UI and SUI was found among women with perineal tears involving any perineal muscles, compared with women with no, labia, or first-degree tears.

Analyze interleukin-1ß, interleukin-6, and tumor necrosis factor-α levels in dry eye and the therapeutic effect of cyclosporine A.

BACKGROUND: Dry eye is a common eye disease. Artificial tears supplements are widely used for the treatment of dry eyes. However, multiple adverse effects have been observed in patients receiving long-term treatment with artificial tears, which may affect the therapeutic effect. AIM: To analyze the characteristics of interleukin-1ß (IL-1ß), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) levels in patients with dry eye and the therapeutic effect of artificial tears combined with cyclosporine A. METHODS: A total of 124 dry eye patients treated at The First People's Hospital of Xining from April 2020 to April 2022 were selected as the observation group, while 20 healthy individuals served as the control group during the same period. Levels of inflammatory markers, including IL-1ß, IL-6, and TNF-α, were analyzed. The observation group was further divided into a study group and a control group, each consisting of 62 patients. The control group received artificial tears, whereas the study group received a combination of artificial tears and cyclosporine A. Inflammatory markers, Schirmer's test (SIT), tear break-up time (TBUT), corneal fluorescein staining (CFS), National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) scores, and adverse events (AEs) were compared between the two groups. RESULTS: The observation group exhibited significantly elevated serum levels of IL-1ß, IL-6, and TNF-α in comparison to the healthy group. Following treatment, the study group demonstrated substantial reductions in IL-1ß, IL-6, and TNF-α levels relative to the control group. Moreover, after treatment, the study group experienced a marked decrease in CFS scores and significant increases in both SIT and BUT levels when compared to the control group. Additionally, significant improvements were observed in the primary symptom of dry eye and secondary symptoms such as photophobia, foreign body sensation, fatigue, red eye, and burning sensation within the study group. Furthermore, post-treatment NEI-VFQ-25 scores across all dimensions exhibited significant enhancements in the study group compared to the control group (P < 0.05). It is noteworthy that significant AEs were reported in both groups throughout the treatment period. CONCLUSION: Cyclosporine A combined with artificial tears is effective in treating dry eye, yielding enhanced outcomes by improving SIT and TBUT levels, reducing CFS scores, and ameliorating vision-related quality of life.

A larger radius of the medial femoral posterior condyle is a risk factor for medial meniscus posterior root tears.

BACKGROUND: Studies have shown an association between medial meniscus posterior root tears (MMPRT) and morphologic characteristics of the bone. However, the association between distal femoral bone morphology and MMPRT, particularly the medial femoral posterior condyle, is poorly understood. Our study aimed to determine the association between the morphologic characteristics of the medial posterior femoral condyle and MMPRT. METHODS: A retrospective case-control study was performed from January 2021 to January 2022. After screening based on the inclusion and exclusion criteria, two matched groups were analyzed: the MMPRT group and the isolated lateral meniscus tears group. The hip-knee-ankle angle (HKA) and Kellgren-Lawrence grade (KLG) were measured on radiographs; the medial tibial slope angle (MTSA), medial tibial plateau depth (MTPD), and radius of the medial femoral posterior condyle (RMFPC) were measured on magnetic resonance imaging (MRI) in both groups. The area under the curve (AUC) and the best cutoff value for predicting MMPRT were calculated by using receiver operating characteristic (ROC) curve analysis. RESULTS: The final analysis included a total of 174 patients (87 MMPRT patients and 87 controls). Significant differences were shown in the RMFPC (17.6 ± 1.0 vs. 16.2 ± 1.0, p < 0.01) and MTSA (6.4 ± 2.0 vs. 4.0 ± 1.3, p < 0.01), which were larger than those of the control group. The MTPD (1.8 ± 0.6 vs. 2.9 ± 0.7, p < 0.01) and HKA (175.4 ± 2.2 vs. 179.0 ± 2.7, p < 0.01) of the injury group were significantly different from the control group, and both were lower than the control group. However, between the MMPRT and control groups on the KLG (2.3 ± 0.6 vs. 2.2 ± 0.6, p = 0.209), there was no statistically significant difference. Among them, the RMFPC cutoff value was calculated to be 16.8 mm by ROC curve analysis, and the sensitivity and specificity were both 81.61%. CONCLUSIONS: This study demonstrated that larger RMFPC, MTSA, smaller MTPD, and HKA were all associated with MMPRT, and RMFPC ≥ 16.8 mm was considered as a significant risk factor for MMPRT.
