Meniscal healing status after medial meniscus posterior root repair negatively correlates with a midterm increase in medial meniscus extrusion.

The second-look arthroscopic score of pullout repair for medial meniscus posterior root tears (MMPRTs) is associated with contemporaneous clinical scores and progression of cartilage damage. However, the relationship among these scores, midterm clinical scores and magnetic resonance imaging (MRI) evaluations is unknown. The relationship between the second-look arthroscopic score at 1 year and the clinical scores or MRI at 3 years was evaluated. Sixty-three patients were included. Medial meniscus extrusion (MME) was evaluated preoperatively and at 3 years postoperatively. Clinical scores were evaluated preoperatively, and 1 and 3 years postoperatively. Meniscal healing status was assessed using the semiquantitative second-look arthroscopic score at 1 year postoperatively. Correlation coefficients between patient characteristics, postoperative clinical scores or second-look arthroscopic score and the change in MME (ΔMME) were evaluated. Multiple regression analysis was performed on the ΔMME to evaluate the effects of patient characteristics and second-look arthroscopic scores. No significant correlation was observed between patient characteristics and ΔMME. In contrast, a significant correlation was found between the second-look arthroscopic score and ΔMME (p < 0.001) and visual analogue scale pain score (p = 0.016) at 3 years postoperatively. In the subitems of the second-look arthroscopic score, width (p < 0.001) and stability (p = 0.009) scores also showed significant correlations with ΔMME. Multiple regression analysis showed a significant association between the second-look arthroscopic score and ΔMME (p = 0.001). The second-look arthroscopic score at 1 year postoperatively correlated with the ΔMME and clinical score at 3 years postoperatively. Second-look arthroscopic scores predict midterm meniscal function after pullout repair of MMPRTs. Level IV.

Validation of spectral sleep scoring with polysomnography using forehead EEG device

IntroductionVisual scoring of sleep electroencephalography (EEG) has long been considered the gold standard for sleep staging. However, it has several drawbacks, including high cost, time-intensiveness, vulnerability to human variability, discomfort to patients, lack of visualization to validate the hypnogram, and no acknowledgment of differences between delta and slow oscillation deep sleep. This report highlights a spectral scoring approach that addresses all these shortcomings of visual scoring. Past algorithms have used spectral information to help classify traditional visual stages. The current method used the clearly visible spectral patterns to develop new spectral stages, which are similar to but not the same as visual stages. Importantly, spectral scoring delivers both a hypnogram and a whole-night spectrogram, which can be visually inspected to ensure accurate scoring.MethodsThis study compared traditional visual scoring of 32-channel polysomnography with forehead-only spectral scoring from an EEG patch worn concurrently. The PSG was visually scored by trained technicians and the forehead patch was scored spectrally. Because non-rapid eye movement (NREM) stage divisions in spectral scoring are not based on visual NREM stages, the agreements are not expected to be as high as other automated sleep scoring algorithms. Rather, they are a guide to understanding spectral stages as they relate to the more widely understood visual stages and to emphasize reasons for the differences.ResultsThe results showed that visual REM was highly recognized as spectral REM (89%). Visual wake was only scored as spectral Wake 47% of the time, partly because of excessive visual scoring of wake during Light and REM sleep. The majority of spectral Light (predominance of spindle power) was scored as N2 (74%), while less N2 was scored as Light (65%), mostly because of incorrect visual staging of Lo Deep sleep due to high-pass filtering. N3 was scored as both Hi Deep (13 Hz power, 42%) and Lo Deep (0–1 Hz power, 39%), constituting a total of 81% of N3.DiscussionThe results show that spectral scoring better identifies clinically relevant physiology at a substantially lower cost and in a more reproducible fashion than visual scoring, supporting further work exploring its use in clinical and research settings.

Memory in female adolescents with congenital adrenal hyperplasia due to 21-hydroxylase deficiency.

In females with congenital adrenal hyperplasia (CAH), the influence of hyperandrogenism and glucocorticoid supplementation on neurocognition is controversial. To identify possible differences in visual working memory and verbal memory in adolescent girls with CAH due to 21-hydroxylase deficiency and matched controls. Moreover, to study if any relationship between variables associated with CAH and the scores of the selected memory tests was present. In total 39 individuals were studied, female adolescents with CAH and age and pubertal stage matched healthy male and female controls (13 in each group). Sociodemographic, clinical, hormonal, and neurocognitive variables were explored. In female adolescents with CAH, variables related to the disease (age at diagnosis, clinical form, time since diagnosis, and glucocorticoid doses) were correlated with the scores obtained for neurocognitive variables. The mean age was 13.9 ± 3.3 years. In female adolescents with CAH the results were worse compared to controls in Free Recall (p = 0.039) and in Visual Memory Span score (p = 0.016). Age at diagnosis was negatively correlated to number of hits (p = 0.04), number recalled backward (p = 0.03), Visual Memory Span test score (p = 0.04) and Total Free Recall (p = 0.04), i.e., memory was worse with later diagnosis. Female adolescents with CAH had worse visual working memory compared to matched controls, but not in verbal memory. Age at diagnosis was negatively associated with the memory tests.

Screening of Rice (Oryza sativa L.) Genotypes for salinity at Reproductive Stage

This study highlights the varying degrees of tolerance to salinity among different rice genotypes. It's interesting to note that despite rice being considered moderately sensitive to salinity. The phenotypic response of 20 rice genotypes with salt stress at EC=12dsm-1 was assessed under hydroponic condition at reproductive stage through visual scoring. Five genotypes, viz., MCM103,CSR27,MCM151-3-2-1-1 , MCM208-12-1-1, AC39416A demonstrated tolerant and 12 genotypes MCM 100, MCM109, MCM125 , MCM1471-1-2-1 , IR04A115, MCM153-1-1-1-1, MCM106-2-10-2-2, MCM258-8-2-1-1-1 , MCM148-2-1-1-1 , IR18T1045, IR100120-B-B-B-11 and MCM159-3-1-1-1 considered as moderately tolerant in the face of salt stress.Conversely,3 genotypes like FL478 ,BPT5204 ,PUSA44 showed susceptibility.

Long-Term Outcomes of Wrist Arthroplasty Using the ReMotion™ Implant in Non-inflammatory Wrist Pathology.

Background: Wrist arthroplasty is increasingly offered to patients with symptomatic wrist arthritis as an alternative to wrist arthrodesis. The purpose of this study was to present our outcomes with the ReMotion™ wrist arthroplasty in a consecutive series of patients with wrist arthritis from non-inflammatory conditions. Methods: Thirteen (eight women, nine dominant wrists) patients, 68 (44-85) years of age with advanced radiocarpal arthritis due to SLAC/SNAC (11) and Kienbock disease (2) had a ReMotion™ (Stryker, Michigan, USA) wrist arthroplasty implanted, and were prospectively followed for 7 (4-9) years. The outcome measures included patient-rated wrist and hand evaluation (PRWHE) score, disabilities of the arm, shoulder and hand questionnaire (QuickDASH) score, visual analogue pain score (0-10) on the radial and ulnar aspect of the wrist at rest (VASrR/VASuR) and activity (VASrA/VASuA), active wrist range of motion (AROM) including flexion, extension, ulnar and radial deviation, pronation and supination and grip and key-pinch strength measured preoperatively and at yearly follow-ups by independent hand therapists. Results: Six patients had ten re-operations during the follow-up including four revisions to a new arthroplasty. Four were considered loose at follow-up. A significant reduction in PRWHE (63 to 12), radial pain at activity (6 to 1) and increased pronation (85° v 90°) was observed. Conclusions: We found a high complication and reoperation rate, two out of 13 had no complications or reoperations. The ReMotion™ arthroplasty should be used with caution in non-inflammatory wrist patients and the patients followed closely. A high reoperation and revision rate can be expected, and surgeons familiar with revision arthroplasty procedures should perform the surgery. Level of Evidence: Level II (Therapeutic).

Metacarpal Fracture Fixation with Intramedullary Screws.

Background: Intramedullary screws (IMS) have become a viable option for metacarpal fracture fixation. To further appraise their utility, this study assessed clinical and patient-reported short- and medium-term outcomes of IMS fixation for extra-articular metacarpal fractures. Methods: A retrospective cohort study was performed in a series of 32 patients (with a total of 37 fractures) who underwent metacarpal fracture fixation over a 42-month period between January 2020 and July 2023. Results: Mean time for return to work was 39.8 days; mean time for return to full function was 88.4 days; total active motion was 250.7° (range: 204.9-270.9); Quick Disabilities of the Arm, Shoulder and Hand score was 2.3 (range: 0-22.7); mean visual analogue pain score was 0.9 out of 10 (range: 0-6) and a single complication was observed. Conclusions: The use of IMS in metacarpal fracture fixation is a practicable surgical option. IMS fixations yields a satisfactory duration for return to function, good postoperative range of movement, modest pain scores and low rates of complications. Level of Evidence: Level IV (Therapeutic).

Outcomes of Arthrodesis of the Metacarpophalangeal Joint of the Thumb for Sequelae of Collateral Ligament Injuries: A Series of 18 Cases with 6-Year Follow-Up.

Background: Untreated or insufficiently treated collateral ligament injuries of the thumb metacarpophalangeal (MP) joint can lead to instability or even osteoarthritis. Arthrodesis is one of the treatment options available for the treatment of the sequelae of collateral ligament injuries. The objective of our study was to evaluate the radiological, clinical and functional outcomes of MP joint arthrodesis performed for sequelae of collateral ligament injuries. Methods: We conducted a retrospective, single-centre study and reviewed the files of patients who had a thumb MP joint arthrodesis following a collateral ligament injury between 2011 and 2019. We collected patient's demographic data and the results of the radiological and clinical examinations. Results: Eighteen patients were included in the study. The average age was of 53.6 years and the time between injury to arthrodesis averaged 7 years. Four patients (22%) had nonunion. In the remaining 14 patients with solid union at an average of 72 months follow-up, the visual analogue pain score at rest was 0.14, the thumb opposition was 82%, grip strength 85%, tip pinch 92% and key pinch 79% of the contralateral side. Conclusions: The clinical and functional results of patients with a successful arthrodesis are satisfactory with restoration of good grip and pinch strength. Despite a lack of thumb MP joint flexion, stability allowed force transmission and may be preferred for manual workers. Level of Evidence: Level IV (Therapeutic).

Impact of the leptin receptor gene on pig performance and quality traits

The recessive T allele of the missense polymorphism rs709596309 C > T of the leptin receptor gene is associated with intramuscular fat. However, its overall impact on pork production is still partial. In this work, we investigated the all-round effects of the TT genotype on lean growth efficiency and carcass, meat and fat quality using data from an experiment that compared the performance of 48 TT and 48 C– (24 CT and 24 CC) Duroc barrows. The TT pigs were less efficient for lean growth than the C– pigs. Although heavier, their carcasses had less lean content, were shorter and had lighter loins. Apart from increasing marbling and saturated fatty acid content, changes caused by the TT genotype in meat and fat quality are likely not enough to be perceived by consumers. The effect on visual marbling score exceeded that on intramuscular fat content, which suggests a direct influence of the T allele on the pattern of fat distribution in muscle. With current low-protein diets, the T allele is expected to be cost-effective only in niche markets where a very high level of marbling is critical.

Development of the Food Acceptance Questionnaire for Thai Partial and Complete Edentulism

This study aimed to develop the Food Acceptance Questionnaire (FAQ) to assess the masticatory ability of Thai older adults (≥60 years). Fifty participants were interviewed using open-ended questions about food they regularly consumed and avoided due to difficulty chewing. From a list of 140 items, 100 were recruited for a trial version of the FAQ. A total of 154 participants responded to the 5-point Likert scale on their chewing perception of each food item (1, impossible to chew; 5, most easily eaten). The average response of each food item was used as the chewing index (CI). The 100 food items were ranked and divided into five grades based on their CIs. Masticatory performance (MP) was objectively assessed by a visual scoring method using gummy jelly (UHA Mikakuto). Two foods from each grade that demonstrated the highest correlation with MP were selected to form the final 10-item FAQ. The FAQ score was calculated by summarizing the responses of 10 items. MP correlated strongly with the FAQ score (r = 0.57, p &lt; 0.001), indicating its predictive validity. Furthermore, the FAQ indicates strong internal consistency (Cronbach’s alpha coefficient = 0.90), indicating high reliability. In conclusion, this newly developed 10-item FAQ is valid and reliable for assessing the masticatory ability of Thai older adults.

Comparing Visual and Software-Based Quantitative Assessment Scores of Lungs’ Parenchymal Involvement Quantification in COVID-19 Patients

(1) Background: Computed tomography (CT) plays a paramount role in the characterization and follow-up of COVID-19. Several score systems have been implemented to properly assess the lung parenchyma involved in patients suffering from SARS-CoV-2 infection, such as the visual quantitative assessment score (VQAS) and software-based quantitative assessment score (SBQAS) to help in managing patients with SARS-CoV-2 infection. This study aims to investigate and compare the diagnostic accuracy of the VQAS and SBQAS with two different types of software based on artificial intelligence (AI) in patients affected by SARS-CoV-2. (2) Methods: This is a retrospective study; a total of 90 patients were enrolled with the following criteria: patients’ age more than 18 years old, positive test for COVID-19 and unenhanced chest CT scan obtained between March and June 2021. The VQAS was independently assessed, and the SBQAS was performed with two different artificial intelligence-driven software programs (Icolung and CT-COPD). The Intraclass Correlation Coefficient (ICC) statistical index and Bland–Altman Plot were employed. (3) Results: The agreement scores between radiologists (R1 and R2) for the VQAS of the lung parenchyma involved in the CT images were good (ICC = 0.871). The agreement score between the two software types for the SBQAS was moderate (ICC = 0.584). The accordance between Icolung and the median of the visual evaluations (Median R1–R2) was good (ICC = 0.885). The correspondence between CT-COPD and the median of the VQAS (Median R1–R2) was moderate (ICC = 0.622). (4) Conclusions: This study showed moderate and good agreement upon the VQAS and the SBQAS; enhancing this approach as a valuable tool to manage COVID-19 patients and the combination of AI tools with physician expertise can lead to the most accurate diagnosis and treatment plans for patients.

Comparative analysis of late gadolinium enhancement assessment techniques for monitoring fibrotic changes in myocarditis follow-up.

To compare the repeatability and interrelation of various late gadolinium enhancement (LGE) assessment techniques for monitoring fibrotic changes in myocarditis follow-up. LGE extent change between baseline and 3-month cardiovascular magnetic resonance (CMR) was compared in patients with acute myocarditis using the full width at half maximum (FWHM), gray-scale thresholds at 5 and 6 standard deviations (SD5 and SD6), visual assessment with threshold (VAT) and full manual (FM) techniques. In addition, visual presence score (VPS), visual transmurality score (VTS), and a simplified visual change score (VCS) were assessed. Intraclass-correlation (ICC) was used to evaluate repeatability, and methods were compared using Spearman's correlation. Forty-seven patients (38 male, median age: 27 [IQR: 21; 38] years) were included. LGE extent change differed among quantitative techniques (p < 0.01), with variability in the proportion of patients showing LGE change during follow-up (FWHM: 62%, SD5: 74%, SD6: 66%, VAT: 43%, FM: 60%, VPS: 53%, VTS: 77%, VCS: 89%). Repeatability was highest with FWHM (ICC: 0.97) and lowest with SD5 (ICC: 0.89). Semiquantitative scoring had slightly lower values (VPS ICC: 0.81; VTS ICC: 0.71). VCS repeatability was excellent (ICC: 0.93). VPS and VTS correlated with quantitative techniques, while VCS was positively associated with VPS, VTS, VAT, and FM, but not with FWHM, SD5, and SD6. FWHM offers the least observer-dependent LGE follow-up after myocarditis. VPS, VTS, and VCS are practical alternatives, showing reliable correlations with quantitative methods. Classification of patients exhibiting either stable or changing LGE relies on the assessment technique. This study shows that LGE monitoring in myocarditis is technique-dependent; the FWHM method yields the most consistent fibrotic tracking results, with scoring-based techniques as reliable alternatives. Recognition of fibrotic changes during myocarditis follow-up is significantly influenced by the choice of the quantification technique employed. The FWHM technique ensures highly repeatable tracking of myocarditis-related LGE changes. Segment-based visual scoring and the simplified visual change score offer practical, reproducible alternatives in resource-limited settings.

Silajathu Rasayana in Management of Rheumatoid Arthritis

Rheumatoid Arthritis is a systemic autoimmune disease characterized by inflammatory arthritis and extra-articular involvement. Considering the pathophysiology, clinical features, and extra-articular manifestations it can be correlated to Vataraktha in Ayurveda. In this case, a 24-year-old female patient who was diagnosed with Juvenile Rheumatoid Arthritis at the age of 15 and was under Disease-modifying anti-rheumatic drug therapy for several years, complaints of pain and swelling over symmetrical joints of upper and lower limbs along with morning stiffness, and evident boutonniere deformity. She also had pain in her left hip for 4 years. Ayurvedic treatment was initiated with a primary focus on Amapachana, Shodhana, and Rasayana therapies. Patient assessment was conducted using a Visual analog scale, DAS28 score, HAQ-DI score, and Ama assessment tool on the 0th and 69th day. DAS 28 score improved from 7.73 to 3.19, and HAQ-DI score improved from 1.63 to 0.88. The visual analog scale was improved from 8 to 4. Following 69 days of treatment incorporated with Ayurvedic treatment procedures coupled with Rasayana therapy, demonstrated a notable amelioration of symptoms, an enhancement in the overall quality of life, and an improvement in laboratory parameters.

133 The effect of sire lines and endpoint cooking temperature on consumer eating experience and visual appeal in pork loin chops

Abstract Prior research and public perception of pork suggest breed influence visual characteristics like color and size and palatability traits like tenderness and flavor of pork chops. Therefore, the objective of this study was to assess consumer perception of visual appeal and palatability of pork loin chops from three sire lines cooked to two different degrees of doneness (DOD). Boneless pork loins from three sire lines (Duroc, Berkshire, and Synthetic) were aged to 14 d post-mortem. Loin quality was then measured, and 2.54-cm chops were frozen from each loin. Chops from each sire line were overwrap-packaged in sets of two and displayed in a retail case with two representative packages per sire line. Panelists rated each package for color, marbling, and size on a just about right (JAR) scale and then indicated their overall liking of each package. Chops from each sire line were cooked to either 63°C or 71°C, cut into 1-cm cubes and two samples from each chop were served to each consumer. Panelists rated 6 samples, each sire line and DOD, for tenderness, flavor, and juiciness on a JAR scale and then rated overall liking. Data were analyzed as a randomized complete block design (RCBD) in SAS 9.4 with panelist age range serving as an influence effect for all panel data. Berkshire chops did not differ (P &amp;gt; 0.08) in redness from other chops, but required 0.13 kg less force to shear, and had a 16.23 cm2 smaller LEA compared with Synthetic and Duroc chops (P &amp;lt; 0.02). Duroc chops had the greatest marbling (P &amp;lt; 0.04) but did not differ in visual color score from other treatments (P &amp;gt; 0.10). There were no differences in consumer visual evaluations (P &amp;gt; 0.45), with traits from all sire lines averaging between 43 and 57 (JAR = 50). Sire line also did not alter visual liking (P = 0.94). There were tendencies for interactions (P &amp;gt; 0.09) between DOD and sire line for consumer sensory evaluation. In general, consumers rated Berkshire chops cooked to 63°C more favorably than other sire line and DOD combinations. Consumers rated chops with different DOD similarly for tenderness and flavor, but tended to score juiciness of chops cooked to 63°C closer to JAR (P = 0.07). Duroc chops were the least tender and least acceptable (P &amp;lt; 0.05). Berkshire chops were juicer than Duroc and Synthetic chops (P &amp;lt; 0.02). Overall, consumers scored all chops between 3.1 and 12.3 units below the JAR line (100-unit scale) regardless of sire line or DOD for tenderness, juiciness, and flavor with overall acceptability within 10 units of neither like nor dislike, which may be indicative of consumers general negative perceptions of pork loin chops.

Comparison of intraperitoneal instillation of Bupivacaine vs Normal Saline for postoperative pain relief after laparoscopic cholecystectomy.

Objective: To evaluate whether local irrigation of Bupivacaine reduces post-operative pain after cholecystectomy. Study Design: Prospective, Randomized Controlled Trial. Setting: Department of Surgery, Government Teaching Hospital, Shahdara Lahore. Period: June 2020 to December 2022. Methods: For this study, 86 participants were divided into two groups, each containing 43 participants (Bupivacaine vs. no Bupivacaine). The control group (Group A) received an infiltration of 15 ml of 0.5% bupivacaine in the sub-diaphragmatic region on the right side and at port sites, while normal saline was administered to Group B. The Visual Analogue Pain Score Scale was employed to assess pain levels at 0-3, 3-5, 5-7, and above 7-10 hours post-surgery (VAS). Results: In this study, the total number of included individuals was 86. Moreover, the overall mean and median ages in months for both groups were 47.7 ± 8.97 and 47 (18-60) respectively, with the majority of patients being male (59 individuals, 68.6%). Furthermore, there was a statistically significant mean difference in pain scores on the visual analogue scale at 0–3 hours, 3–5 hours, 5–7 hours, and 7–10 hours (p-value &lt; 0.05). Similarly, there was a statistically significant mean difference in pain scores on the visual analogue scale after more than three to five hours, more than seven hours, and more than ten hours (p-value &lt; 0.05). Conclusion: Consequently, we inferred that intraperitoneal and local infiltration of Bupivacaine following laparoscopic cholecystectomy significantly reduced the level of postoperative discomfort and the requirement for analgesics.

Rheumatoid arthritis disease activity significantly impacts on the severity of interstitial lung disease

ObjectivesRheumatoid arthritis (RA) related interstitial lung disease (ILD) impacts on the treatment strategy and its prognosis in patients with RA. However, the relationship between RA disease activity and the severity of comorbid ILD has not been fully investigated. This study aimed to investigate the impact of RA disease activity on the severity of comorbid ILD in detail based on currently established visual scoring method along with physiological severity.MethodsConsecutive patients with RA visiting to our Rheumatology Centre between December 2020 and December 2023 were analysed. The radiological severity of ILD was evaluated by averaging the extent of the combined lesion of ground glass opacity, reticulation and honeycombing in 5% increments in six representative high-resolution computed tomography slices ranging from 0% (no involvement) to 100% (all lung fields affected) according to Goh and Walsh’s method. Associations between the radiological and physiological severity of ILD and patients’ features were investigated using linear regression analysis.ResultsAmong 124 patients (32 men, 92 women), the median age was 70 years, and the median disease duration was 2.92 years. Radiological severity of ILD was 0% (without ILD) in 107 (86.2%), ILD with extent < 10% in nine (7.2%), ILD with extent ≥10% and < 20% in three (2.4%), ILD with extent ≥20% in five (4.0%). Both disease activity score (DAS)28-erythrocyte sedimentation rate (ESR) (standardized coefficient = 0.199, P = 0.03) and rheumatoid factor titre (standardized coefficient = 0.247, P = 0.01) were significantly associated with the radiological quantitative severity of ILD in multivariate analysis adjusted for age, sex, disease duration, smoking status and anti-citrullinated peptide antibody titre. DAS28-ESR was significantly associated with forced vital capacity% predicted (standardized coefficient = -0.230, P = 0.047).ConclusionsDisease activity of RA was significantly associated with the severity of RA-ILD both radiologically and physiologically.

Defining Minimal Clinically Important Difference, Patient Acceptable Symptomatic State and Substantial Clinical Benefit for the Visual Analog Scale Pain Score After Arthroscopic Rotator Cuff Repair

IntroductionPatient satisfaction after arthroscopic rotator cuff repair (RCR) is commonly assessed with patient-reported outcome measures (PROMs), and there is an increased need to establish clinical relevance within these measures. The purpose of this study was to (1) define Minimal Clinically Important Difference (MCID), Patient Acceptable Symptomatic State (PASS) and Substantial Clinical Benefit (SCB) for the visual analog scale (VAS) pain score in patients undergoing arthroscopic RCR, and (2) identify preoperative predictors of achieving each of these threshold values. MethodsData from consecutive patients who underwent primary arthroscopic rotator cuff repair study between 2010 and 2016 were prospectively collected. Baseline data and VAS pain scores were collected preoperatively and at 1 year and 2 years postoperatively. MCID, PASS and SCB were determined using an anchor-based approach, with anchor questions assessing postoperative satisfaction and expectation fulfilment. Multivariate logistic regression analysis was also used to identify preoperative predictors for achieving MCID, PASS and SCB. ResultsA total of 286 patients were included in the final analysis, with an average age of 60.2 ± 10.4 and the majority being female (61.2%). The values for VAS pain score identified to represent MCID, PASS, and SCB, respectively at 1-year postoperatively were: 5, 2 and 1. The rates of achieving clinically significant improvement based on VAS were 60.5%, 63.3% and 57.2% respectively. A higher preoperative VAS was predictive for achieving MCID (odds ratio [OR], 1.84; P<0.01). ConclusionThis study identified threshold VAS pain scores of 5, 2 and 1 for achieving MCID, PASS, and SCB, respectively, at 1-year follow-up after arthroscopic rotator cuff repair. A higher preoperative VAS pain score was also identified as a statistically significant predictor of attaining MCID after arthroscopic rotator cuff repair. Level of evidenceII

A Visualization and Radiation Treatment Plan Quality Scoring Method for Triage in a Population-Based Context

PurposeTo develop a clinically intuitive and easily understandable scoring method using statistical metrics to visually determine the quality of a radiation treatment plan. Methods and MaterialsData from 111 head and neck cancer patients were used to establish a percentile-based scoring system for treatment plan quality evaluation on both a plan-by-plan and objective-by-objective basis. The percentile scores for each clinical objective and the overall treatment plan score were then visualized using a daisy plot. To validate our scoring method, 6 physicians were recruited to assess 60 plans each using a scoring table consisting of a 5-point Likert scale (with scores ≥3 considered passing). Spearman correlation analysis was conducted to assess the association between increasing treatment plan percentile rank and physician rating, with Likert scores of 1 and 2 representing clinically unacceptable plans, scores of 3 and 4 representing plans needing minor edits, and a score of 5 representing clinically acceptable plans. Receiver operating characteristic curve analysis was used to assess the scoring system's ability to quantify plan quality. ResultsOf the 60 plans scored by the physicians, 8 were deemed as clinically acceptable; these plans had an 89.0th ± 14.5 percentile value using our scoring system. The plans needing minor edits or deemed unacceptable had more variation, with scores falling in the 62.6th ± 25.1 percentile and 35.6th ± 25.7 percentile, respectively. The estimated Spearman correlation coefficient between the physician score and treatment plan percentile was 0.53 (P < .001), indicating a moderate but statistically significant correlation. Receiver operating characteristic curve analysis demonstrated discernment between acceptable and unacceptable plan quality, with an area under the curve of 0.76. ConclusionsOur scoring system correlates with physician ratings while providing intuitive visual feedback for identifying good treatment plan quality, thereby indicating its utility in the quality assurance process.

Association of Retinal Thickness at Month 1 Post-Treatment with Later Thickness and Visual Acuity in Central Vein Occlusion

Purpose: To investigate the association of retinal thickness 1 month post-randomization (1 month after first study injection with aflibercept or bevacizumab) with later retinal thickness, visual acuity, and number of treatments in eyes with central or hemiretinal vein occlusion enrolled in the SCORE2 trial. DesignCohort study using data from a randomized multicenter clinical trial. MethodsAnalysis included 350 SCORE2 participants through 2 years of follow-up. Main outcome measures are central subfield thickness (CST) on spectral domain optical coherence tomography, best-corrected visual acuity letter score (VALS), and number of treatments for macular edema. CST was classified as thin (≤216µm), medium (>216µm and ≤300µm), or thick (>300µm). ResultsAt Month 1, 15% (51/350) of study eyes were in the thin CST class, 57% (199/350) in the medium CST class, and 29% (100/350) in the thick CST class. Of eyes with thin CST at Month 1, 89-96% were also thin during Months 2-12. Over all visits studied, the VALS of eyes in the medium Month 1 CST class was significantly greater than the Month 1 thin class. During Months 6-12 (p<0.001) and 12-24 (p <0.001), but not during Months 0-6 (p=0.36) when monthly treatment was protocol-specified, the mean number of treatments for macular edema per study eye was highest in the thick CST class and lowest in the thin CST class. The thin CST class is significantly more likely to have disorganization of the retinal inner layers inside the central subfield, more paracentral acute middle maculopathy at Month 1, and a history of anti-VEGF treatment prior to trial enrollment. ConclusionsEyes with a thin CST at Month 1 were more likely to be in their Month 1 CST class during Months 2-12 than eyes in the thick or medium Month 1 CST classes. Eyes in the medium CST class had the best VALS, with fewest treatments in the thin class after Month 6. These findings suggest that having a post-treatment thin CST can be as detrimental to visual acuity as having a post-treatment thick CST.

Comparison of Clinical Outcomes After Different Surgical Approaches for Lateral Epicondylitis: A Systematic Review and Meta-analysis.

Lateral epicondylitis (LE) is one of the most common causes of lateral elbow pain. When nonoperative treatment fails, 1 of the 3 surgical approaches-open, percutaneous, or arthroscopic-is used. However, determining which approach has the superior clinical outcome remains controversial. To review the outcomes of different operative modalities for LE qualitatively and quantitatively. Systematic review; Level of evidence, 4. This review was performed and reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Studies published in PubMed, Medline (via EBSCO), and ScienceDirect databases that treated LE with open, percutaneous, or arthroscopic approaches with at least 12 months of follow-up were included. Study quality was assessed using the Cochrane Risk of Bias 2 tool and the Methodological Index for Non-Randomized Studies score. The primary outcome was the success rate of each operative treatment approach-open, percutaneous, and arthroscopic. From an initial search result of 603 studies, 43 studies (n = 1941 elbows) were ultimately included. The arthroscopic approach had the highest success rate (91.9% [95% CI, 89.2%-94.7%]) compared with the percutaneous (91% [95% CI, 87.3%-94.6%]) and open (82.7% [95% CI, 75.6%-89.8%]) approaches for LE surgery with changes in the mean visual analog scale pain score of 5.54, 4.90, and 3.63, respectively. According to the Disabilities of the Arm, Shoulder and Hand score, the functional outcome improved in the arthroscopic group (from 54.11 to 15.47), the percutaneous group (from 44.90 to 10.47), and the open group (from 53.55 to 16.13). The overall improvement was also found in the Mayo Elbow Performance Score, the arthroscopic group (from 55.12 to 90.97), the percutaneous group (from 56.31 to 87.65), and the open group (from 64 to 93.37). Arthroscopic surgery had the highest rate of success and the best improvement in functional outcomes among the 3 approaches of LE surgery.

“Counting Sheep PSG”: EEGLAB-Compatible Open-Source MATLAB Software for Signal Processing, Visualization, Event Marking and Staging of Polysomnographic Data

BackgroundProgress in advancing sleep research employing polysomnography (PSG) has been negatively impacted by the limited availability of widely available, open-source sleep-specific analysis tools. New methodHere, we introduce Counting Sheep PSG, an EEGLAB-compatible software for signal processing, visualization, event marking and manual sleep stage scoring of PSG data for MATLAB. ResultsKey features include: (1) signal processing tools including bad channel interpolation, down-sampling, re-referencing, filtering, independent component analysis, artifact subspace reconstruction, and power spectral analysis, (2) customizable display of polysomnographic data and hypnogram, (3) event marking mode including manual sleep stage scoring, (4) automatic event detections including movement artifact, sleep spindles, slow waves and eye movements, and (5) export of main descriptive sleep architecture statistics, event statistics and publication-ready hypnogram. Comparison with existing methodsCounting Sheep PSG was built on the foundation created by sleepSMG (https://sleepsmg.sourceforge.net/). The scope and functionalities of the current software have made significant advancements in terms of EEGLAB integration/compatibility, preprocessing, artifact correction, event detection, functionality and ease of use. By comparison, commercial software can be costly and utilize proprietary data formats and algorithms, thereby restricting the ability to distribute and share data and analysis results. ConclusionsThe field of sleep research remains shackled by an industry that resists standardization, prevents interoperability, builds-in planned obsolescence, maintains proprietary black-box data formats and analysis approaches. This presents a major challenge for the field of sleep research. The need for free, open-source software that can read open-format data is essential for scientific advancement to be made in the field.
