Anterior Cruciate Ligament Reconstruction Utilizing Double Adjustable-Loop Suspensory Fixation Devices Provides Good Clinical Outcomes in Patients under the Age of 40 Years at Two-Year Follow-Up.

Background: Anterior cruciate ligament reconstruction (ACLR) using double adjustable fixation gained popularity in the last decade due to its minimally invasive technique. However, suspensory fixation devices could be related to recurrent instability, poor clinical outcomes, and patient dissatisfaction. The present study aims to evaluate the clinical outcomes following ACLR using double adjustable-loop suspensory fixation devices in the demanding population of young patients. Methods: Between 2019 and 2022, 95 patients with knee post-traumatic anterior cruciate ligament insufficiency were treated with primary ACLR using semitendinosus quadrupled graft and double adjustable-loop suspensory fixation devices and followed for at least two years. Concomitant lesions were also treated at the same surgical time. The knee examination form of the International Knee Documentation Committee (IKDC) was used to assess clinical evaluation, and the return to physical activities using the Tegner Activity Scale was recorded. Patient-reported objective measures (PROMs) were also evaluated, including the IKDC subjective and Lysholm scores. Results: Sixty-six males and twenty-nine females with a mean age of 23.8 (range 18-37) and a mean BMI of 24.9 (SD ± 2.42) kg/m2 were included in this study. All patients were evaluated clinically as normal or nearly normal at the final follow-up. PROMs also significantly improved postoperatively (p < 0.05) compared to the preoperative values. The Tegner Activity Scale increased from 2 to 7, the IKDC mean score improved from 43.9 (±8.9) to 93.3 (±12.3), and the modified Lysholm from 47.3 (±11.1) to 92.9 (±16.6). No complications or adverse events were recorded. Conclusions: Anterior cruciate ligament reconstruction utilizing double adjustable-loop suspensory fixation devices provides good clinical and functional outcomes in young patients at a two-year follow-up.

Salivary flow rate, subjective oral dryness and dental caries 5 years after haematopoietic cell transplantation

BackgroundThe aim of this study was to describe salivary flow rate, subjective oral dryness and dental caries 5 years post haematopoietic cell transplantation (HCT).MethodsHCT survivors of a previous longitudinal observational cohort study in the Netherlands (the H-OME study) were invited to participate in this additional follow-up after 5 years (the HOME2 study). During the additional follow-up appointment, stimulated (SWS) and unstimulated whole saliva (UWS) was collected, participants rated subjective oral dryness on a 0 – 10 scale, and caries lesions were assessed. Furthermore, dental records, including treatments and radiographs, were requested for the 5 years preceding and the 5 years following transplantation. Paired t-tests were performed to determine changes in UWS and SWS flow rates and subjective oral dryness from pre-HCT, and to compare the number of caries-related dental treatments (restorations, endodontic treatments or extractions) before and after HCT. Hyposalivation of UWS (< 0.2 mL/min) and SWS (< 0.7 mL/min) at 3 and 12 months, was used to explore the predictive potential of hyposalivation on a high dental treatment need (> 3 treatments) over the 5 years post-HCT.ResultsFive years post-HCT, 39 HCT survivors were included. The mean UWS flow rate was 0.36 mL/min (SD 0.26) and the mean SWS flow rate 1.02 (SD 0.57); survivors were diagnosed with a median of 0 dentine lesions (range 0 – 12) and 73% reported a subjective oral dryness score ≥ 1. Survivors underwent a median of 3 (range 0 – 20) dental treatments during the 5 years following transplantation. The mean difference in UWS 5 years post-HCT compared to pre-HCT was 0.03 (95% CI: -0.07 – 10.12), the mean difference for SWS was -0.18 (95% CI: -0.45 – 0.08) and for subjective oral dryness 1.2 (95% CI: 0.2 – 2.1). In the 5 years post-HCT, non-significantly more treatments were performed compared to the 5 years pre-HCT (mean difference: 0.5, 95%CI: -1.2 – 2.2). Seventy eight percent of patients with hyposalivation of SWS at 12 months had a high dental treatment need, compared with 38% with no hyposalivation.ConclusionsFive years post-HCT, mean UWS and SWS flow rates were not significantly different from pre-HCT levels but subjective oral dryness scores were elevated.

Measuring the value of teachers from traditional certification pathways in Texas: A comprehensive study

While teacher preparation in the United States continues a long period of decline, the largest-producing state, Texas, is experiencing substantial changes in how it prepares teachers. The number of teachers prepared by traditional university pathways continues to decline, and the number from alternative pathways is rising. Using extensive data from Texas, we find that traditionally prepared teachers from universities obtain significantly higher student learning gains than alternatives. We use value-added models to estimate changes in student test scores in many grade levels and test subjects as a function of teacher preparation pathway. We compare all Traditional programs to all Alternative programs, and we compare all For-Profit programs to all Not for-Profit programs. For most subjects and grade levels, students learn significantly more from Traditional or Not for-Profit program teachers: 0.02 to 0.05 in standard deviation units. There is not one significant estimate in any model where students learn more from Alternative and For-Profit programs teachers than they do from Traditional and Not For-Profit program teachers.

Analyzing Online Conversations on Reddit: A Study of Stress and Anxiety Through Topic Modeling and Sentiment Analysis.

This study analyses the topic of stress and anxiety in 3,765 Reddit posts to determine key themes and emotional undertones using natural language processing (NLP) techniques. Five major category topics are identified from the posts using the latent Dirichlet allocation (LDA) algorithm. The topics identified are general discontent and lack of direction; panic and anxiety attacks; physical symptoms of anxiety, stress, and mental health concerns; and seeking help for anxiety. Sentiment analysis with the help of TextBlob showed a neutral score, for the most part: an average polarity score of 0.009 and a subjectivity score of 0.494. Several kinds of visualizations, including word clouds, bar charts, and pie charts, have been used to show the distribution and importance of these topics. These findings underscore the important role played by online communities in extending their support to those in distress because of mental health problems. This information is very important to mental health professionals and researchers. This study shows the effectiveness of using a combination of topic modeling and sentiment analysis to identify problems related to mental health discussed on social media. These results direct the possibilities for future research in using advanced NLP techniques and expanding to larger datasets.

Exploring the Relationships Between Clinical Examination Findings, Subjective Reported Symptoms and Objective Nasal Patency Measures in Nasal Obstruction: A Baseline NAIROS Sub-Study Analysis.

The role of objective nasal airflow measures using peak nasal inspiratory flow (PNIF) and rhinospirometry in supporting clinical examination findings when offering patients septoplasty remain undefined. To explore the baseline relationships between clinical examination findings, subjective reported symptoms and objective nasal patency measures in nasal obstruction. This is a sub-study of the NAIROS trial. Participants with nasal obstruction secondary to septal deviation were included in this NAIROS sub-study. The side of septal deviation, enlargement of inferior turbinate (IT), the need for IT reduction if septoplasty was being performed, the area of septum deflecting into the airway and observer rated airway block (ORAB-arbitrarily divided by <50% and >50% blockage) were assessed by clinicians. The subjective score of nasal obstruction was assessed using the Double Ordinal Assessed Subjective Scale (DOASS). Objective nasal patency measures (e.g., nasal partitioning ratio, [NPR] and PNIF) were measured using PNIF and rhinospirometry. The mean NPR for left-sided, both-sided and right-sided septal deviation was -0.35, -0.02 and 0.51, respectively (p < 0.001). There was very weak correlation between the requirement for IT reduction and PNIF change (0.13, p < 0.01). There was no difference in mean PNIF (94 L/min vs. 93 L/min) and mean DOASS (0.33 vs. 0.38) for participants with ORAB rated <50% and >50%. The mean NPR for participants with ORAB >50% was higher than for those with ORAB <50% (0.51 vs. 0.41, p = 0.002). There was strong correlation between the DOASS and NPR (+0.737, p < 0.001). The mean DOASS score for right-sided, both-sided and left-sided septal deviation was 0.32, 0.05 and -0.29, respectively (p < 0.001). This study identified strong relationships between the clinician rated side of septal deflection, the patient reported DOASS and the objective NPR measurements. NPR and the clinician rated degree of airway blockage were concordant.

Comparison of Performance for Cochlear-Implant Listeners Using Audio Processing Strategies Based on Short-Time Fast Fourier Transform or Spectral Feature Extraction.

We compared sound quality and performance for a conventional cochlear-implant (CI) audio processing strategy based on short-time fast-Fourier transform (Crystalis) and an experimental strategy based on spectral feature extraction (SFE). In the latter, the more salient spectral features (acoustic events) were extracted and mapped into the CI stimulation electrodes. We hypothesized that (1) SFE would be superior to Crystalis because it can encode acoustic spectral features without the constraints imposed by the short-time fast-Fourier transform bin width, and (2) the potential benefit of SFE would be greater for CI users who have less neural cross-channel interactions. To examine the first hypothesis, 6 users of Oticon Medical Digisonic SP CIs were tested in a double-blind design with the SFE and Crystalis strategies on various aspects: word recognition in quiet, speech-in-noise reception threshold (SRT), consonant discrimination in quiet, listening effort, melody contour identification (MCI), and subjective sound quality. Word recognition and SRTs were measured on the first and last day of testing (4 to 5 days apart) to assess potential learning and/or acclimatization effects. Other tests were run once between the first and last testing day. Listening effort was assessed by measuring pupil dilation. MCI involved identifying a five-tone contour among five possible contours. Sound quality was assessed subjectively using the multiple stimulus with hidden reference and anchor (MUSHRA) paradigm for sentences, music, and ambient sounds. To examine the second hypothesis, cross-channel interaction was assessed behaviorally using forward masking. Word recognition was similar for the two strategies on the first day of testing and improved for both strategies on the last day of testing, with Crystalis improving significantly more. SRTs were worse with SFE than Crystalis on the first day of testing but became comparable on the last day of testing. Consonant discrimination scores were higher for Crystalis than for the SFE strategy. MCI scores and listening effort were not substantially different across strategies. Subjective sound quality scores were lower for the SFE than for the Crystalis strategy. The difference in performance with SFE and Crystalis was greater for CI users with higher channel interaction. CI-user performance was similar with the SFE and Crystalis strategies. Longer acclimatization times may be required to reveal the full potential of the SFE strategy.

Evaluation of fatigue and fatigability in people with Duchenne muscular dystrophy using a dynamic arm support – a pilot study

Background Due to progressive muscle wasting and weakness in patients with Duchenne Muscular Dystrophy (DMD), physical fatigability increases, upper extremity function reduces, which negatively impacts quality of life. Assistive technology such as dynamic arm supports (DAS) may help reduce this fatigability. This study aims to assess whether the novel Yumen ‘EXone’ DAS can reduce upper extremity fatigue and fatigability in DMD patients and healthy controls (HC), both with and without the DAS. Additionally, longitudinal changes in DMD patients were evaluated. Methods Five DMD patients from the Yumen Bionics pioneer program and five HCs participated. Two submaximal tests simulating drinking and reaching were performed for two minutes, each with and without DAS. DMD participants completed these tests twice, at baseline (T0) and after 6-9 months (T1), while HCs completed them once. Physical fatigability was measured by the number of repetitions and changes in surface electromyography (sEMG) amplitude. Subjective fatigue was assessed using the Borg Scale (6-20) Rate of Perceived Exertion (RPE). Results DMD participants generally performed more repetitions with the DAS than without. HCs showed similar or increased repetitions with the DAS. Assessing fatigability with sEMG was difficult due to the compensatory mechanisms used for the tests. Subjective fatigue scores on the Borg Scale were lower with the DAS for both DMD patients and HCs. Conclusion The Yumen ‘EXone’ DAS effectively reduces both fatigue and fatigability in DMD patients and healthy controls. Despite the methodological shortcomings, this research is one of the first studies investigating the impact of DAS on fatigue and fatigability.

Unveiling the Neurocognitive Impact of Food Aroma Molecules on Pleasantness Perception: Insights From EEG and Key Brain LFT Activation

ABSTRACTFood aroma molecules have the potential to influence people's emotions through the olfactory pathway and are anticipated to emerge as a new method for regulating emotional states, owing to their simplicity and high acceptance. Current research on food aroma predominantly centres on the physicochemical properties and formation mechanisms of aroma components, neglecting the effects of aroma molecules in emotional regulation. Moreover, the evaluation of pleasantness, a pivotal dimension of emotions, lacks objective assessment methods. In this study, sensory assessments of pleasantness for 12 aroma compounds were gathered from 45 subjects, and their correlation with the brain's activity responses in the left frontal‐temporal lobe (LFT) and right frontal‐temporal lobe (RFT) using electroencephalogram (EEG) signals was analysed. The results revealed a close relationship between brain activity in the LFT and the perception of aroma pleasantness. Furthermore, a substantial correlation was observed between the α, β and γ frequency bands in the LFT and the subjective pleasantness scores. These findings demonstrate that the LFT plays a critical role in evaluating the pleasantness of aroma molecules, and that changes in the power of the α, β and γ bands serve as important evaluation indicators. Consequently, this method offers a new objective means for assessing pleasantness to find higher pleasantness aroma molecules and the emotional regulation of food aroma.

A prospective longitudinal study assessing the impact of rhinovirus and bacterial infections in acute exacerbations of chronic rhinosinusitis.

Acute exacerbations of chronic rhinosinusitis (AECRS) are thought to arise from common viral infections progressing to secondary bacterial infections. However, the pathophysiology of AECRS remains poorly understood due to a lack of prospective longitudinal studies. We conducted a one-year prospective longitudinal study involving chronic rhinosinusitis (CRS) adults. At baseline, we assessed subjective symptom scores using a validated upper respiratory infection questionnaire (WURSS), sinonasal outcome testing scores (SNOT-22), and endoscopic scores (modified Lund-Kennedy score). Every 2weeks, we contacted subjects to collect WURSS and SNOT-22 scores. If WURSS scores were ≥1 and SNOT-22 scores were ≥ 8.9 compared with baseline, subjects underwent an AECRS assessment. We identified rhinovirus (RV) incidence through viral nasal brushings at each visit and bacterial infection through bacterial swabs if mucus scores were ≥1. Thiry-five of 80 CRS subjects reported at least one AECRS episode during the year, predominantly occurring in the fall and winter seasons. RV infections were detected in 8 of 35 cases, bacterial infections in 17 of 35, and co-occurring infections in 7 of 35. All subjects with AECRS visits exhibited significantly higher endoscopic scores compared with baseline. Subjects with co-occurring RV and bacterial infections demonstrated higher disease severity compared with those with either RV or bacterial infection, or no infection. In a one-year prospective longitudinal study involving CRS adults, we identified significant risk factors for AECRS including seasonality and the presence of RV and bacterial infections. These data suggest a standard definition of AECRS and the need to target RV and bacterial infections if we are to help reduce disease severity.

Outcomes of Common Peroneal Nerve Decompression.

Common peroneal nerve (CPN) neuropathy is the most common lower extremity mononeuropathy. When delayed or no recovery from CPN neuropathy is suspected, surgical CPN decompression (CPND) is considered to relieve symptoms. This study aimed to evaluate patient outcomes post-CPND performed by a single surgeon at a tertiary medical center. Patient outcomes after CPND performed by a single surgeon were reviewed. Motor, sensation, and pain scores post-CPND were assessed in 47 of the 46 patients. Patient demographics, including age, concomitant morbidities, time from injury to surgery, and body mass index (BMI), were also analyzed for correlations with outcomes after CPND by logistic regression. 29/34 patients with impaired motor function improved by at least one motor grade, 19/42 with altered sensation reported restored normal sensation, and 31/37 reported improved pain after CPND. No correlation of patient demographic factors with motor or pain improvement after CPND was observed. However, a BMI greater than 29.15 and a time between injury and surgery exceeding 506 days were associated with lower odds of reporting restored sensation. Operative decompression of CPN neuropathy improves objective motor scores and subjective sensation and pain scores.

Relationship Between Patient-reported Outcome Measures and Accelerometer-measured Physical Activity and Sleep in Patients With Postherpetic Neuralgia.

Available treatment for chronic neuropathic pain is still limited, and the positive effects are modest. Thus, clinicians aim to improve activity and quality of life despite pain. The objective monitoring of activity is attracting attention in chronic pain assessments. Therefore, we objectively evaluated daytime activity and sleep in patients with postherpetic neuralgia (PHN), using actigraphy to determine risk factors for decreased activity. Participants with PHN wore an actigraph (a wristwatch-like accelerometer) on the nondominant hand. The actigraph measured day-time activity and sleep, which were compared with participant-reported subjective pain and sleep assessments. Fifty-four individuals with PHN who visited our outpatient clinic completed questionnaires and a week of actigraph monitoring. Subjective scores of pain intensity, neuropathic pain, disability in daily life, pain-catastrophizing thoughts, and insomnia were all well correlated. However, the actigraph-monitored activity levels, using 2 equations, and sleep quality were not associated with any pain or sleep-related subjective scores. The discrepancy between the subjective and objective scores in this study may be due to (1) features of PHN, an archetype of peripheral neuropathic pain affecting no motor nerves, (2) actigraph measurement limitations regarding the sedentary life of the elderly, or (3) activity misperception, a new proposition explaining the discrepancy between subjective and objective measures of activity, similar to the sleep state misperception. In patients with PHN, high pain intensity may be reported in those with highly maintained activity, in which treatment must be selected cautiously to prevent interruption of their physical abilities.

Association between folate intake and radiographic progression, pain function scores in subjects with radiographic knee osteoarthritis: Data from the osteoarthritis initiative.

Folate has an important role in the functioning of the musculoskeletal system, including modulation of inflammation, immunity, cartilage regeneration, prevention of osteoporosis, and maintenance of muscle strength, but evidence on the association between folate intake and knee pain, functional scores, and radiographic progression in patients with knee osteoarthritis (OA) is still limited. Our population-based cohort was extracted from the osteoarthritis initiative (OAI), focusing on individuals with prevalent radiographic knee OA (with a Kellgren-Lawrence score ≥2). Folate consumption was determined using the food frequency questionnaire. Data regarding the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores and radiographic readings were collected over 48 months. We analyzed the compiled data using generalized additive mixed models. Our cohort consisted of 1472 OA patients (626 men and 846 women, mean [SD] age 62.35 [8.92]). At the 48-month follow-up, we observed a significant correlation between higher folate intake and a slower progression of knee pain and functional scores, as evidenced by a statistically significant decrease in the WOMAC total score, WOMAC pain subscale score, and WOMAC function/disability subscale score (p < .05). The fully adjusted models estimated a reduction of -0.028 points per 50 μg/1000 kcal of daily folate intake on the WOMAC pain subscale, -0.117 points on the WOMAC function subscale, and -0.160 points on the total WOMAC scale. Furthermore, our nonparametric fit analysis suggested that a higher intake of folate might decelerate the radiographic progression of OA. Stratified analyses indicated that an increase in folate consumption might particularly benefit men, older adults, overweight and obese individuals, and those with a higher dietary fiber intake. Higher folate intake is correlated with improved knee function and reduced pain in patients with knee OA and might deter the radiographic progression of OA. The benefits appear to be more pronounced in men, older adults, overweight and obese individuals, and those with a higher dietary fiber intake.

Outcomes After Extracorporeal Shockwave Therapy for Chronic Noninsertional Achilles Tendinopathy Compared With Chronic Insertional Achilles Tendinopathy: A Retrospective Review.

Extracorporeal shockwave therapy (ESWT) is a noninvasive treatment modality that is used in the treatment of chronic Achilles tendinopathy (AT). To (1) retrospectively assess outcomes after ESWT for both noninsertional AT (NAT) and insertional AT (IAT) at >1-year follow-up and (2) identify potential predictors of outcomes. Cohort study; Level of evidence, 3. Chart review was conducted to identify patients who underwent ESWT for AT with a minimum of 1-year follow-up. Data collected and assessed included patient demographic characteristics, pathological characteristics including the location of AT (NAT or IAT), presence of a Haglund deformity, and severity of tendon degeneration on magnetic resonance imaging (MRI), in addition to treatment characteristics including number of sessions and intensity of ESWT. The Victorian Institute of Sports Assessment-Achilles (VISA-A) and visual analog scale (VAS) pain scores were obtained before ESWT, 6 months after ESWT, and at final follow-up. Failures were also recorded, which were defined as no improvement in VISA-A or VAS scores or need for surgical intervention. Linear regression was performed to identify potential predictors of inferior subjective clinical outcomes and failures. Survival analysis was conducted using Kaplan-Meier curves. The study included 52 patients with IAT and 34 patients with NAT. The mean follow-up in the NAT cohort was 22.3 ± 10.2 months and the mean follow-up in the IAT cohort was 26.8 ± 15.8 months. Improvements in VISA-A and VAS scores were observed in the NAT cohort at 6-month follow-up and at final follow-up (P < .05). Improvements in VISA-A and VAS scores were recorded in the IAT cohort at 6-month follow-up, which subsequently deteriorated at final follow-up. In the NAT cohort, the failure rate at 6-month follow-up was 11.8%, which increased to 29.4% at final follow-up. In the IAT cohort, the failure rate at 6-month follow-up was 32.7%, which increased to 59.6% at final follow-up. Predictors of inferior subjective clinical outcomes and failures in the NAT cohort included pre-ESWT subjective clinical score, male sex, presence of a cardiovascular risk factor, and more severe MRI grading of tendinopathy. Predictors of inferior subjective clinical outcomes and failures in the IAT cohort included pre-ESWT subjective clinical score and more severe MRI grading of tendinopathy. Superior subjective clinical outcomes together with a lower failure rate were maintained for >1 year in the NAT cohort compared with the IAT cohort, calling into question the long-term benefit of ESWT for patients with IAT.

Full-reference calibration-free image quality assessment

Objective Image Quality Assessment (IQA) methods often lack of linearity of their quality estimates with respect to scores expressed by human subjects and therefore IQA metrics undergo a calibration process based on subjective quality examples. However, example-based training presents a challenge in terms of generalization hampering result comparison across different applications and operative conditions. In this paper, new Full Reference (FR) techniques, providing estimates linearly correlated with human scores without using calibration are introduced. We show that on natural images, application of estimation theory and psychophysical principles to images degraded by Gaussian blur leads to a so-called canonical IQA method, whose estimates are linearly correlated to both the subjective scores and the viewing distance. Then, we show that any mainstream IQA methods can be reconducted to the canonical method by converting its metric based on a unique specimen image. The proposed scheme is extended to wide classes of degraded images, e.g. noisy and compressed images. The resulting calibration-free FR IQA methods allows for comparability and interoperability across different imaging systems and on different viewing distances. A comparison of their statistical performance with respect to state-of-the-art calibration prone methods is finally provided, showing that the presented model is a valid alternative to the final 5-parameter calibration step of IQA methods, and the two parameters of the model have a clear operational meaning and are simply determined in practical applications. The enhanced performance are achieved across multiple viewing distance databases by independently realigning the blur values associated with each distance.

The Arthroscopically Guided Bristow-Latarjet Procedure With Cortical Button Fixation: A Minimum 10-Year Follow-up

Background: Despite improved visualization, the use of arthroscopic surgery to perform the Latarjet procedure has not decreased the rates of complications and glenohumeral osteoarthritis (OA) in the long term. Many of the reported complications are related to the use of screws for bone block fixation with freehand drilling. Purpose: To evaluate the long-term (at a minimum 10-year follow-up) clinical and radiological outcomes of the arthroscopic Bristow-Latarjet procedure using a posterior guided drilling technique and suture button for coracoid bone graft fixation. Study Design: Case series; Level of evidence, 4. Methods: Consecutive patients who underwent the arthroscopic Bristow-Latarjet procedure with suture button fixation between 2011 and 2013 were reviewed by 2 independent evaluators. Complications and revision surgery were recorded, and we evaluated patient-reported outcomes including subjective scores, recurrence of shoulder instability (dislocation or subluxation), range of motion limitations, and return to sports. Patients had radiographs taken at least 10 years after surgery to assess glenohumeral OA according to the Samilson-Prieto classification system and computed tomography scans to assess bone block positioning and healing. Results: A total of 65 consecutive patients (68 shoulders) with a mean follow-up of 135 months (range, 120-156 months) were included. The mean age at the time of surgery was 25 ± 8 years; 7 patients had previous failed Bankart repair. At follow-up, 94% (64/68) of the shoulders had no recurrence of instability. The 4 cases of instability recurrence were traumatic and occurred at 3 weeks (a fall), 4 months, 2 years, and 7 years after surgery. No hardware failures, coracoid fractures, or neurological complications were observed. Overall, 61 patients (94%) were still participating in sports, with 44 (68%) at the same or higher level. Range of motion showed nonsignificant restrictions in external rotation with the arm at the side (7° ± 9°) and with the arm at 90° of abduction (9° ± 10°) compared with the contralateral side. Additionally, 11 shoulders (16%) had some residual anterior apprehension on clinical examination. At last follow-up, 77% (47/61) of the shoulders had no OA development or progression. Previous failed Bankart repair was a risk factor for the development of OA. Patients with OA had significantly lower Subjective Shoulder Value scores (79% vs 91%, respectively; P = .01) and decreased external rotation with the arm at the side (40° vs 65°, respectively; P = .001) compared with patients with no or little OA. Conclusion: The arthroscopically guided Bristow-Latarjet procedure with suture button fixation is a safe and durable surgical treatment method for recurrent anterior shoulder instability, allowing a high rate of return to sports without significant motion restrictions and no or little OA in the long term.

Residential Instability and Children’s Mental Health: Emotional and Behavioral Consequences of Frequent Relocation

Residential instability, characterized by frequent relocations, poses significant risks to children’s mental health, impacting their emotional and behavioral development. This study explores the emotional and behavioral consequences of frequent relocations on children aged 5 to 15, using a mixed-methods approach that combines longitudinal quantitative data and qualitative interviews. The findings reveal that children who experience three or more relocations within five years exhibit significantly higher levels of anxiety, depression, and attachment issues, alongside increased externalizing behaviors such as aggression and defiance and internalizing behaviors such as social withdrawal and anxiety. Academic performance also suffers, with lower average scores in core subjects like mathematics and reading observed among frequently relocated children. These outcomes are moderated by factors such as parental support, community integration, and economic stability, highlighting the complex interplay between individual, familial, and contextual variables. The study underscores the need for targeted interventions and supportive policies to mitigate the negative impacts of residential instability and promote children’s mental health and well-being. Future research should focus on the long-term effects, specific vulnerable populations, and protective factors to better understand and address the challenges faced by children in unstable housing situations.

Association of the Inlay Structure Used in the Modified Bristow Procedure With Accelerated Bone Union: Comparing the Cuistow and Modified Bristow Procedures.

The Chinese unique inlay Bristow (Cuistow) procedure is a modified Bristow surgery in which an inlay (mortise-and-tenon) structure is added to the contact surface between the coracoid tip and the glenoid. Patients who have undergone the Cuistow procedure have had satisfying clinical performance and excellent postoperative bone healing rates (96.1%). To compare the clinical and radiographic outcomes after the arthroscopic Cuistow procedure and the arthroscopic Bristow procedure. Cohort study; Level of evidence, 3. A total of 91 patients who underwent either the Cuistow or Bristow procedure between January 2017 and March 2018 were selected, and 69 patients (70 shoulders; 35 in the Cuistow group and 35 in the Bristow group) were included. Clinical assessment at minimum 24 months postoperatively, including the visual analog scale for pain and instability, American Shoulder and Elbow Surgeons score, Rowe score, subjective shoulder value score, and active range of motion, was completed by independent observers and compared with values collected preoperatively. Assessment with 3-dimensional computed tomography scans was performed preoperatively; immediately after the operation; at 3, 6, and 12 months postoperatively; and at the final follow-up. A total of 69 patients (70 shoulders) were included, with a mean follow-up duration of 34.41 ± 5.99 months (range, 24-50 months). Both groups saw significant improvement in visual analog scale for pain and instability, American Shoulder and Elbow Surgeons, Rowe, and subjective shoulder value scores at the final follow-up compared with the preoperative values (P < .001 for all), with no significant between-group differences on any clinical outcomes at the final follow-up. The 3-month postoperative graft union rate on computed tomography was significantly higher in the Cuistow group compared with the Bristow group (82.9% vs 51.4%, respectively, P = .003), although the graft union rate at the final follow-up was not significantly different (94.3% vs 85.7%, respectively; P = .449). Patients receiving the Cuistow procedure had equivalent clinical outcomes and a significantly higher bone union rate at 3 months postoperatively than those in the Bristow group. The inlay structure used in the Cuistow procedure was found to be associated with accelerated bone union.

Verification of image quality improvement by deep learning reconstruction to 1.5T MRI in T2-weighted images of the prostate gland.

This study aimed to evaluate whether the image quality of 1.5T magnetic resonance imaging (MRI) of the prostate is equal to or higher than that of 3T MRI by applying deep learning reconstruction (DLR). To objectively analyze the images from the 13 healthy volunteers, we measured the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the images obtained by the 1.5T scanner with and without DLR, as well as for images obtained by the 3T scanner. In the subjective, T2W images of the prostate were visually evaluated by two board-certified radiologists. The SNRs and CNRs in 1.5T images with DLR were higher than that in 3T images. Subjective image scores were better for 1.5T images with DLR than 3T images. The use of the DLR technique in 1.5T MRI substantially improved the SNR and image quality of T2W images of the prostate gland, as compared to 3T MRI.

Double-Level Torsional Osteotomy in Severe Torsional Malalignment: A Surgical Technique

Background: Torsional malalignment of the femur and/or tibia is associated with patellar maltracking, and torsional osteotomies have shown to improve clinical symptoms. In patients with severe torsional malalignment, a double-level torsional osteotomy may be necessary. Indications: Symptomatic torsional malalignment leading to patellofemoral maltracking associated with anterior knee pain and/or patellofemoral instability. Technique Description: A double-level torsional osteotomy correcting both increased internal femoral torsion and increased external tibial torsion, is described. Meticulous preoperative deformity analysis and planning of the osteotomy is mandatory. An arthroscopy of the knee is performed first to evaluate the patellofemoral joint and patellar tracking. Tibial torsional correction is performed by a lateral approach. A biplanar osteotomy is performed, and the amount of torsional correction is controlled by 2 Schanz screws. Osteosynthesis can be done via a bended 5-hole DC-Plate or an angle-stable plate. The femoral osteotomy is performed by a medial approach. A uniplanar osteotomy is performed perpendicular to the mechanical axis of the femur. The amount of torsional correction is controlled by 2 Schanz screws. Osteosynthesis is achieved by an angle-stable plate. Results: Double-level torsional osteotomy has been shown to be an effective treatment for patients with patellar dislocation or subluxation associated with severe torsional malalignment. In a series of 18 patients, double-level osteotomy led to improved patellofemoral stability, decreased pain, and increases subjective outcome scores. Discussion/Conclusion: In patients with patellofemoral problems caused by a combined increased tibial external torsion and increased femoral internal torsion, a double-level torsional osteotomy is able to correct torsional angles to normal. Available clinical data on this procedure are promising. Patient Consent Disclosure Statement: The author(s) attests that consent has been obtained from any patient(s) appearing in this publication.

Comparison of Subjective and Biomechanical Outcomes Between Proprioceptive Training and Modified Broström-Gould Surgery for Chronic Ankle Instability: A Randomized Controlled Trial.

Both proprioceptive training and modified Broström-Gould surgery can improve ankle stability in patients with chronic ankle instability (CAI), but further biomechanical evaluation is necessary to determine the optimal treatment. To compare the clinical outcomes and biomechanical changes after proprioceptive training versus modified Broström-Gould surgery in patients with CAI. Randomized controlled trial; Level of evidence, 2. A total of 56 patients with CAI were assigned randomly to either a nonoperative group (n = 28) who underwent 3 months of proprioceptive training or an operative group (n = 28) who underwent modified Broström-Gould surgery. Foot and Ankle Ability Measure (FAAM) scores, foot pressure during walking, center of pressure (COP) velocity, and time for the COP to reach the balance boundary (time to boundary [TTB]) during single-leg standing were collected before the intervention (baseline) and at 3, 6, and 12 months after the intervention. Two-way repeated-measures analysis of variance was used to compare group differences and changes over time. The nonoperative group had significant improvements from baseline in FAAM-Sports score and significantly decreased TTB in both the anterior-posterior and medial-lateral directions at all timepoints, while the operative group showed significant improvements only in FAAM-Sports scores and TTB and COP velocity in the anterior-posterior direction at 6 and 12 months postintervention. During walking, the nonoperative group had significantly increased peak force under the medial foot at 3 months, which dropped back to baseline levels at 12 months, while the operative group had significantly increased peak force under the medial midfoot and hindfoot that persisted until 12 months (P < .05). In this study, both proprioceptive training and modified Broström-Gould surgery led to improved subjective functional scores, foot pressure distribution during walking, and postural stability during standing for patients with CAI but with different biomechanical patterns. Proprioceptive training led to an earlier recovery of sports function and better medial-lateral stability recovery, while surgery provided more persistent results.
