Comparing the tolerability of preservative-free tafluprost versus preserved latanoprost in the management of glaucoma and ocular hypertension - an observer blinded active-control trial.

Dry eye is a condition related to long-term topical eye therapy. We wish to evaluate the effectiveness and tolerability of preservative free prostaglandin drops versus benzalkonium chloride containing prostaglandin drops in the treatment of glaucoma. Patients undergoing prostaglandin monotherapy underwent a washout period of at least 1 month after which baseline measurements of dry eye severity were taken. Patients were randomised to receive either 0.0015% tafluprost drops or 0.005% latanoprost preserved with 0.02% benzalkonium chloride. Repeat measurements were taken after a 2-month interval. Thirty-five patients completed randomised treatment. No significant difference between groups was found in objective and subjective measurements of dry eye severity. No significant difference was found in measurement of treatment effectiveness. Preservative-free and benzalkonium chloride-containing drops were found to be equally effective in lowering IOP with no significant difference in either subjective or objective measurements of dry eye severity.

Objective measurement of movement variability using wearable sensors predicts ASD outcomes in infants at high likelihood for ASD and ADHD.

Early motor delays and differences are common among children with autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). Yet, little work has shown whether there are early atypical motor signs that differentiate these groups. Quantitative measures of movement variability hold promise for improving the identification of subtle and specific differences in motor function among infants and toddlers at high likelihood for ASD and ADHD. To this end, we created a novel quantitative measure of movement variability (movement curvature) and conducted a preliminary investigation as to whether this measure improves outcome predictions. We used a wearable triaxial accelerometer to evaluate continuous motion-based activity in infants at high and low likelihood for ASD and ADHD at 12, 18, 24, and 36 months of age. At 36 months, participants were categorized into three outcome groups: ASD (n = 19), ADHD concerns (n = 17), and a comparison group (n = 82). We examined group differences in movement curvature and whether movement curvature is predictive of a later ASD or ADHD concerns classification. We found that movement curvature was significantly lower in infants with later ASD diagnosis at 18, 24, and 36 months of age compared to infants with either ADHD concerns or those in the comparison group. Movement curvature was also a significant predictor of ASD at 18, 24, and 36 months (AUC 0.66-0.71; p = 0.005-0.039) and when adjusting for high ASD likelihood at 18 and 24 months (AUC 0.90, p = 0.05-0.019). These results indicate that lower movement curvature may be a feature of early motor differences in infants with later ASD diagnosis as early as 18 months of age.

Three-Dimensional Photography for Evaluating the Effectiveness of Botulinum Toxin Injection for Masseter Hypertrophy.

Masseter hypertrophy is a common condition that causes a undesirable square face, and often treated with botulinum toxin type A (BoNTA). Subjective assessments of BoNTA effectiveness vary from physician to patient, necessitating an objective approach for evaluation. This study introduces three-dimensional photography (3DP) for the first time in clinical assessment to evaluate BoNTA treatment for masseter hypertrophy. Ten patients received 36U of BoNTA at three injection points on each side masseter muscle. 3DP scanner using Artec Eva® was taken at the first, third, and sixth postoperative months for objective evaluation. Patient's self-perceived prominence, patients self-rated satisfaction, and physicians provided 5-grade scores were the subjective indicators. A significant decrease in left masseter volume at the sixth month (P = 0.002, P = 0.004 at rest and clenching, respectively) was observed. Patient's self-perceived prominence decreased at the first (P = 0.021) and third (P = 0.039) months. Physicians' scores significantly decreased at all postoperative months. No significant changes were noted in the right masseter volume and patients self-rated satisfaction. Patient self-rated satisfaction did not consistently correlate with objective measures, except for left masseter with clenching at the sixth month. Three-dimensional photography accurately quantifies facial changes post-BoNTA treatment. Despite objective improvements, patient satisfaction may not align consistently. Reliable assessment tools are crucial in cosmetic surgery to manage expectations and prevent disputes. This journal requires that authors assign a level of evidence to each article.

Sleep deficiency and symptoms of pain, fatigue, and depressed mood in youth with and without childhood systemic lupus erythematosus.

To describe and compare sleep deficiency and symptoms of pain, fatigue, and depressed mood in youth with childhood Systemic lupus erythematosus (cSLE) to a healthy comparison group of youth; and to test the associations between sleep and symptoms of pain, fatigue, and depressed mood in youth with cSLE. Forty-three youth (23 youth with cSLE; 20 age, sex-matched healthy youth) wore actigraphs and completed sleep diaries for 10 days, and completed self-report questionnaires on sleep quality, pain, fatigue, and depressed mood. On average, both groups had a total sleep time of less than 7 hours. Youth with cSLE had worse sleep efficiency (73.3%) and sleep regularity index scores (55.4) compared to the healthy comparison group of youth (79.2%, 60.1, respectively). Youth with cSLE had worse pain (p = .03) and fatigue (p = .004) compared to the healthy comparison group. Negative associations were found among self-reported sleep quality, sleep satisfaction, and symptoms of pain, fatigue, and depressed mood in youth with cSLE and wake after sleep onset was positively associated with fatigue. Poor sleep efficiency and sleep irregularity accompanied by symptoms of pain, fatigue, and depressed mood was prevalent in youth with cSLE. Youth with lupus should be encouraged to maintain a regular sleep schedule. Since, this is the first study to incorporate objective sleep and sleep regularity measures in youth with cSLE, additional studies with objective and self-report sleep measures are needed to replicate our findings.

The relationship of gastroesophageal reflux disease and asthma control

ABSTRACT Purpose To study whether ACT responses are confounded by gastro-esophageal status (GERD), and if this is in concordance with the variation in Forced Expiratory Volume in 1 second (FEV1%) and Fractional Excretion of Nitric Oxide (FeNO). Materials and Methods This is a prospective cohort study (n = 307). Patients were surveyed for demographics data, and underwent ACT scoring, FEV1% and FeNO testing. Results Patients with GERD had mean ACT scores that were 4.1 (p < .001) lower than without-GERD group. Not-well-controlled asthmatics (FEV1% <80, high FeNO) with-GERD had mean ACT scores that were 2.9 (p < .001) for FEV1% <80 and 3.8 (p = .008) for high FeNO lower than without-GERD group respectively. Well-controlled asthmatics (FEV1% ≥80, low FeNO) with-GERD had mean ACT scores that were 5.2 (p < .001) for FEV1% ≥80 and 5.1 (p < .001) for low FeNO lower than without-GERD group respectively. Conclusion Our study demonstrates that symptoms of GERD can lead to an inaccurate perception of asthma control and ACT as compared to objective measures, such as FEV1% and FeNO. Hence, this can lead to mismanagement of asthma, especially when objective measures are not conducted along with ACT.

Safety-in-Numbers for route choice of bicycle trips: A choice experiment approach for commuters

Safety-in-Numbers (SiN) implies that the risk of collision per road user is less when there are more road users. Although the available literature has confirmed the existence of SiN as an objective measure of safety, the effect on perceived safety, especially in the context of bicycle riders, has received much less attention. This study investigates the SiN effect on the perceived safety of bicycle riders that influences route choice behavior. A stated preference survey was performed in the South Delhi district of Delhi. The effect of attributes like posted speed limit, the volume of motorized traffic, bicycle infrastructure, and bicycle traffic/ crowding on route choice behavior was investigated. A binary logit model was developed to quantify the effect of these attributes on route choice. The results indicate that, in general, riders prefer routes with more bicycle traffic, hence validating SiN. But the effect does not always hold. For some riders, in the presence of dedicated bicycle infrastructure, when the perceived safety is higher, the presence of more bicycle traffic acts as crowding and demotivates riders to choose that route. The study also reveals that riders prefer routes with a low volume of motorized traffic and dedicated bicycle infrastructure. The outcomes suggest that a policy that encourages infrastructural development to provide lateral separation will encourage more people, hence increasing bicycle mode share as well as the perceived safety of riders.

Effects of noise exposure on stress hormone changes during task performance in young Korean men: quasi-experimental study

ABSTRACT Numerous studies have suggested that noise exposure might be associated with changes in stress hormone levels. However, quantitative evidence for these effects in humans is rare and remains controversial. This study aimed to investigate the acute effects of exposure to noise and its different levels on stress hormone changes in task performance. Quasi-experimental noise exposure environment was established for 90 male university student volunteers in their twenties, and each was exposed to different noise levels during task performance. The stress hormones tested included cortisol, adrenocorticotropic hormone (ACTH), adrenaline, and noradrenaline. A one-way ANOVA was performed to investigate differences in hormone levels measured in the three groups according to the noise exposure levels (35, 45, or 75 dB). Analysis of covariance (ANCOVA) was used to adjust for confounding factors that might affect hormone levels. After adjusting for confounders, significant exposure-dependent differences were found in hormone levels in salivary cortisol, serum cortisol, serum ACTH, and serum adrenaline. The amount of hormonal increase in 75 dB exposure group compared to 35 or 45 dB groups was detected. Similar results were also seen in the rate of change analysis. Our findings indicate that short-term noise exposure during task performance elevates stress hormone levels. Further, the extent of stress hormone alterations varies with noise exposure levels. Changes in hormone levels are an objective measure that may be used to identify health effects and stress responses in various noise environments.

Associations between personality traits and different types of mobile phone use while driving: A cross-sectional study

This study investigated the interplay between personality traits and mobile phone use while driving (MPUWD) among 392 drivers in Zahedan. The study revealed that individuals with higher levels of agreeableness and conscientiousness were less likely to MPUWD. For each unit increase in agreeableness or conscientiousness, there was an 8 % decrease in the odds of MPUWD, along with decreases in various phone-related activities. Conversely, individuals with higher levels of neuroticism were more likely to engage in MPUWD, with increased odds for various activities. Open-minded individuals tended to avoid MPUWD, showing decreases in odds for certain activities with each unit increase. Additionally, higher extraversion scores were associated with decreased odds of taking pictures while driving. Notably, the study highlighted the positive association between agreeableness and hands-free MPUWD. Additionally, the study demonstrated that personality traits molded TBP constructs and moral norms. The multiple regression model revealed that agreeableness exhibited significant relationships with behavior intention, while conscientiousness was linked to attitude, perceived behavior control, and subjective norms. Furthermore, moral norms demonstrated significant associations with both agreeableness and conscientiousness. However, the study's reliance on self-reported measures may introduce biases, highlighting the importance of incorporating objective measures and observational data in future research to enhance validity.

Transcutaneous Discrimination of Fetal Heart Rate from Maternal Heart Rate: A Fetal Oximetry Proof-of-Concept.

Intrapartum care uses electronic fetal heart rate monitoring (EFHRM) for over 50years to indirectly assess fetal oxygenation. However, this approach has been associated with an increase in cesarean delivery rates and limited improvements in neonatal hypoxic outcome. To address these shortcomings, a novel transabdominal fetal pulse oximeter (TFO) is being developed to provide an objective measurement of fetal oxygenation. Previous studies have evaluated the performance of TFO on pregnant ewe. Building on the animal model, this study aims to determine whether TFO can successfully capture human fetal heart rate (FHR) signals during non-stress testing (NST) as a proof-of-concept. Eight ongoing pregnancies meeting specific inclusion criteria (18-40years old, singleton, and at least 36weeks' gestation) were enrolled with consent. Each study session was 15 to 20min long. Reference maternal heart rate (MHR) and FHR were obtained using finger pulse oximetry and cardiotocography for subsequent comparison. The overall root-mean-square error was 9.7BPM for FHR and 4.4 for MHR, while the overall mean-absolute error was 7.6BPM for FHR and 1.8 for MHR. Bland-Altman analysis displayed a mean bias ± standard deviation between TFO and reference of -3.9 ± 8.9BPM, with limits of agreement ranging from -21.4 to 13.6 BPM. Both maternal and fetal heart rate measurements obtained from TFO exhibited a p-value < 0.001, showing significant correlation with the reference. This proof-of-concept study successfully demonstrates that TFO can accurately differentiate maternal and fetal heart signals in human subjects. This achievement marks the initial step towards enabling fetal oxygen saturation measurement in humans using TFO.

Yoga Exercises as a Therapeutic Approach for Adults with Insomnia to Promote better Sleep: A Randomized Control Trial

Background: Insomnia is a prevalent sleep disorder that significantly impacts the quality of life and is associated with various health complications, including high blood pressure, heart disease, diabetes, anxiety, and depression. Traditional treatments for insomnia often involve pharmacological interventions, but there is growing interest in alternative therapies such as yoga. This study investigates the efficacy of yoga as a therapeutic approach to improving sleep quality in adults with insomnia. Objective: The objective of this study was to evaluate the effects of a structured yoga program on sleep quality and sleep latency in adults diagnosed with insomnia. Methods: The study employed a cross-sectional design conducted at multiple healthcare facilities, including the Physiotherapy Outpatient Department at Holy Family Hospital, Benazir Bhutto Hospital, and District Headquarters Hospital in Rawalpindi. The study duration was four months, involving 54 participants selected through random sampling techniques. Inclusion criteria included adults aged 18 to 65 years diagnosed with insomnia according to the International Classification of Sleep Disorders (ICSD) or the Diagnostic and Statistical Manual of Mental Disorders (DSM). Exclusion criteria included severe medical or psychiatric disorders, substance abuse, pregnancy, or recent changes in sleep medication. Participants in the intervention group engaged in a standardized yoga program consisting of gentle yoga postures, controlled breathing techniques, and mindfulness meditation, conducted twice weekly for eight weeks, with each session lasting 60 minutes. The control group received standard care for insomnia. Data collection involved subjective assessments of sleep quality using validated questionnaires and objective measures through polysomnography. Statistical analysis was performed using SPSS version 25.0, with independent sample t-tests comparing means between groups and repeated measures ANOVA for within-group analysis. Results: The yoga group showed significant improvements in subjective sleep quality and sleep latency. The mean sleep quality score improved from 2.18 ± 0.66 pre-intervention to 0.92 ± 0.37 post-intervention (p=0.0001), while the control group showed a less marked improvement from 2.37 ± 0.48 to 2.03 ± 0.18 (p=0.0012). Sleep latency in the yoga group decreased from 3.00 ± 0.00 to 1.29 ± 0.40 (p=0.0002), whereas the control group showed a reduction from 2.44 ± 0.49 to 2.11 ± 0.31 (p=0.0013). ANOVA results confirmed the statistical significance of these findings, with an F-value of 69.897 for sleep quality (p=0.0001) and 361.947 for sleep latency (p=0.0002). Conclusion: The findings indicate that a structured yoga program significantly improves sleep quality and reduces sleep latency in adults with insomnia. Yoga appears to be an effective non-pharmacological intervention for managing insomnia, offering a viable alternative to traditional treatments.

Global longitudinal strain as a predictor of mortality in patients with cardiogenic shock

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): Aarhus University Dagmar Marshalls Fond. Background The assessment of left ventricular (LV) function through transthoracic echocardiography (TTE) is essential for guiding diagnosis and treatment in cases of cardiogenic shock (CS). Myocardial global longitudinal strain (GLS) provides an objective and reproducible measure of systolic function, independently predicting outcomes in acute heart failure, regardless of left ventricular ejection fraction (LVEF). However, whether assessment of GLS can predict mortality in patients with CS remains unknown. Purpose In this study, we aimed to evaluate the prognostic significance of GLS in patients with CS. Methods Data from cardiac intensive care unit (CICU) patients admitted between 2007 and 2018 with CS who received vasoactive agents and/or mechanical circulatory support were analysed. GLS (as absolute values) and biplane LVEF were measured via TTE performed within 24 hours of CICU admission. Patients with CS were categorised based on the GLS quartile: mild (GLS &amp;gt;9.7%), moderate (7.0% &amp;lt; GLS &amp;lt;9.6%), severe (5.0% &amp;lt; GLS &amp;lt; 6.9%), and very severe (GLS ≤ 4.9%). CICU and in-hospital mortality were compared across GLS categories, and the relationship between GLS and mortality was assessed using multivariable logistic regression. Results The study included 626 patients with a median age of 68.6 years, a median LVEF of 31% (IQR 24 to 40%), and a median GLS of 7.0% (IQR 5.0 to 9.7%). In-hospital mortality was 29.1%. As GLS deteriorated, there was an increasing need for vasopressors (P&amp;lt;0.001). Patients with progressively lower GLS exhibited significantly higher CICU and in-hospital mortality across the GLS quartiles (Figure A; P&amp;lt;0.001). Patients in the severe (adjusted OR 2.67; p&amp;lt;0.001) and very severe category (adjusted OR 3.54; P&amp;lt;0.001) had significantly increased risk of in-hospital death compared with mild category. In multivariable analysis, every 1% decrease in GLS corresponded to a 14% higher risk of in-hospital mortality (P&amp;lt;0.001). Finally, GLS outperformed LVEF for discrimination of in-hospital mortality (P=0.002), and when both measurements were included in the same multivariable model, only GLS remained significant. When patients were divided according to whether they had GLS and/or LVEF below the median value, patients with low GLS had higher mortality irrespective of the LVEF (Figure B). Conclusion In patients with CS, GLS assessment surpasses LVEF in its prognostic value and improves risk stratification. Routine evaluation of GLS should be considered for patients with CS.Figure AFigure B

A systematic review to determine the effect of strategies to sustain chronic disease prevention interventions in clinical and community settings: study protocol

BackgroundThe primary purpose of this review is to synthesise the effect of strategies aiming to sustain the implementation of evidenced-based interventions (EBIs) targeting key health behaviours associated with chronic disease (i.e. physical inactivity, poor diet, harmful alcohol use, and tobacco smoking) in clinical and community settings. The field of implementation science is bereft of an evidence base of effective sustainment strategies, and as such, this review will provide important evidence to advance the field of sustainability research.MethodsThis systematic review protocol is reported in accordance with the Preferred Reporting Items for Systematic review and Meta-Analysis (PRISMA) checklist. Methods will follow Cochrane gold-standard review methodology. The search will be undertaken across multiple databases, adapting filters previously developed by the research team, data screening and extraction will be performed in duplicate, strategies will be coded using an adapted sustainability-explicit taxonomy, and evidence will be synthesised using appropriate methods (i.e. meta-analytic following Cochrane or non-meta-analytic following SWiM guidelines). We will include any randomised controlled study that targets any staff or volunteers delivering interventions in clinical or community settings. Studies which report on any objective or subjective measure of the sustainment of a health prevention policy, practice, or programme within any of the eligible settings will be included. Article screening, data extraction, risk of bias, and quality assessment will be performed independently by two review authors. Risk of bias will be assessed using Version 2 of the Cochrane risk-of-bias tool for randomised trials (RoB 2). A random-effect meta-analysis will be conducted to estimate the pooled effect of sustainment strategies separately by setting (i.e. clinical and community). Sub-group analyses will be undertaken to explore possible causes of statistical heterogeneity and may include the following: time period, single or multi-strategy, type of setting, and type of intervention. Differences between sub-groups will be statistically compared.Discussion/conclusionThis will be the first systematic review to determine the effect of strategies designed to support sustainment on sustaining the implementation of EBIs in clinical and community settings. The findings of this review will directly inform the design of future sustainability-focused implementation trials. Further, these findings will inform the development of a sustainability practice guide for public health practitioners.Systematic review registrationPROSPERO CRD42022352333.

Electroencephalographic Correlates of Clinical Severity in the Natural history study of RTT and Related Disorders.

This study was undertaken to characterize quantitative electroencephalographic (EEG) features in participants from the Natural history study of RTT and Related Disorders and to assess the potential for these features to act as objective measures of cortical function for Rett syndrome (RTT). EEG amplitude and power features were derived from the resting EEG of 60 females with RTT (median age = 10.7 years) and 26 neurotypical females (median age = 10.6 years). Analyses focus on group differences and within the RTT group, associations between the EEG parameters and clinical severity. For a subset of participants (n = 20), follow-up data were available for assessing the reproducibility of the results and the stability in the parameters over 1 year. Compared to neurotypical participants, participants with RTT had greater amplitude variability and greater low-frequency activity as reflected by greater delta power, more negative 1/f slope, and lower theta/delta, alpha/delta, beta/delta, alpha/theta, and beta/theta ratios. Greater delta power, more negative 1/f slope, and lower power ratios were associated with greater severity. Analyses of year 1 data replicated the associations between 1/f slope and power ratios and clinical severity and demonstrated good within-subject consistency in these measures. Overall, group comparisons reflected a greater predominance of lower versus higher frequency activity in participants with RTT, which is consistent with prior clinical interpretations of resting EEG in this population. The observed associations between the EEG power measures and clinical assessments and the repeatability of these measures underscore the potential for EEG to provide an objective measure of cortical function and clinical severity for RTT.

Perioperative alpha blockers in voiding dysfunction secondary to prostate biopsy: A meta‐analysis

AbstractIntroduction and ObjectivesVoiding dysfunction remains a common side effect postprostate biopsy leading to significant morbidity. Alpha blockers have emerged as a potential therapeutic option to mitigate this risk, with various centres already incorporating its use in practice. Despite this, the literature regarding its efficacy remains inconclusive. Hence, a systematic review was performed to quantify the effect of perioperative alpha blockers on prostate biopsy‐related voiding function.MethodsA systematic search in MEDLINE, Embase and PubMed between January 1989 and July 2023 was performed to identify relevant articles. Two independent reviewers independently screened abstracts, full texts and performed data extraction. Data including International Prostate Symptom Scores (IPSS), voiding flow rates (Qmax), postvoid residuals (PVR), rates of acute urinary retention (AUR) and quality of life (QoL) scores were extracted. Results were combined in an inverse variance random effects meta‐analysis.ResultsA total 808 patients from six randomised controlled trials (RCTs) comparing alpha blockers to controls were included. All articles excluded patients with pre‐existing voiding dysfunction. Pooled outcomes demonstrated statistically significant differences favouring alpha blocker usage in all objective and subjective measures including IPSS (mean difference 4.21, 95% confidence interval [CI] 2.58–5.84, p &lt; 0.00001), PVR (mean difference 20.41 mL, 95% CI 3.44–37.39, p = 0.02), Qmax (mean difference 3.07 mL/s, 95% CI 2.55–3.59, p &lt; 0.00001), QoL (weighted‐mean difference 0.82, CI 0.17–1.48, p = 0.01) as well as overall risk of AUR (odds ratio 0.22, CI 0.09–0.55, p = 0.001). There was variable heterogeneity (I2 = 0–86%) between outcomes.ConclusionsThis review highlights the potential role of alpha blockers in improving urinary function and reducing adverse voiding outcomes postprostate biopsy. The standard practice of incorporating the usage of perioperative alpha blockers may be considered to reduce the morbidity of voiding complications secondary to prostate biopsy.

Review of Image Quality Assessment Methods for Compressed Images

The compression of images for efficient storage and transmission is crucial in handling large data volumes. Lossy image compression reduces storage needs but introduces perceptible distortions affected by content, compression levels, and display environments. Each compression method generates specific visual anomalies like blocking, blurring, or color shifts. Standardizing efficient lossy compression necessitates evaluating perceptual quality. Objective measurements offer speed and cost efficiency, while subjective assessments, despite their cost and time implications, remain the gold standard. This paper delves into essential research queries to achieve visually lossless images. The paper describes the influence of compression on image quality, appropriate objective image quality metrics (IQMs), and the effectiveness of subjective assessment methods. It also provides an overview of the existing literature, surveys, and subjective and objective image quality assessment (IQA) methods. Our aim is to offer insights, identify challenges in existing methodologies, and assist researchers in selecting the most effective assessment approach for their needs.

JAKinhibs in Psoriatic Disease: Analysis of the Efficacy/Safety Profile in Daily Clinical Practice

Psoriatic disease (PsD) affects multiple clinical domains and causes a significant inflammatory burden in patients, requiring comprehensive evaluation and treatment. In recent years, new molecules such as JAK inhibitors (JAKinhibs) have been developed. These have very clear advantages: they act quickly, have a beneficial effect on pain, are well tolerated and the administration route is oral. Despite all this, there is still little scientific evidence in daily clinical practice. This observational, retrospective, single-center study was carried out in patients diagnosed with PsA in the last two years, who started treatment with Tofacitinib or Upadacitinib due to failure of a DMARD. The data of 32 patients were analyzed, and the majority of them (75%) started treatment with Tofacitinib. Most had moderate arthritis activity and mild psoriasis involvement according to activity indices. Both Tofacitinib and Upadacitinib demonstrated significant efficacy, with rapid and statistically significant improvement in joint and skin activity indices, C-reactive protein reduction, and objective measures of disease activity such as the number of painful and inflamed joints. Although there was some difference in the baseline characteristics of the cohort, treatment responses were comparable or even superior to those in the pivotal clinical trials. In addition, there was a low frequency of mild adverse events leading to treatment discontinuation and no serious adverse events. These findings emphasize the strong efficacy and tolerability of JAKinhibs in daily clinical practice, supporting their role as effective therapeutic options for patients with PsD.

Kinematics of 90° change of direction in young football players: Insights for ACL injury prevention from the CUTtheACLstudy on 6008 trials.

To investigate the 90° change of direction (COD) task in an extensive cohort of competitive healthy football players within the CUTtheACLstudy and to provide normative values and differences between males and females for full-body kinematics based on two-dimensional (2D) video analysis and scoring system. One-thousand-and-two competitive football (soccer) players (age 16.3 ± 2.8 years, 264 females) were prospectively enroled. Each player performed three preplanned 90° COD tasks per limb. The 2D evaluation was performed through objective measures (collected through three high-speed cameras) of frontal and sagittal plane joint kinematics at the cut initial foot contact (IC) and maximum knee flexion angle. A previously published scoring system was adopted to measure the movement quality of the COD task. The scoring system included five criteria (limb stability [LS], pelvis stability [PS], trunk stability [TS], shock absorption [SA], movement strategy [MS]) ranked from 0/2 (nonadequate) to 2/2 (adequate) with a maximum score of 10/10. Normative data were provided for all the variables; statistical differences between male and female players were investigated (p < 0.05). A total of 6008 valid attempts were included. Frontal plane knee projection angle (FPKPA) at initial contact was 24.4 ± 9.8° (95thpercentile: FPKPA > 40°). The total score was ≤4/10 in 71.2% of the trials, the lowest subscores were LS and PS. Female players showed different movement patterns with lower hip and trunk flexion both at IC and maximum knee flexion angle (p < 0.01, ES = 0.41-0.64). Female players also showed worse scores than males in SA, MSand total score (p < 0.01). Female players seem more prone to stiffer lower limb strategy and greater pelvis-trunk frontal plane instability than males. Clinicians could adopt normative data and sex-specific differences in players' movement techniques to improve ACL injury risk mitigation protocols. Level IV.

P-LDPC coded image transmission with OFDM over underwater acoustic channel

Underwater environment is still an attractive area to explore and exploit by human beings. However, underwater characteristics limit communications due to harsh channel conditions, and efficient channel codes are essential to deploy. This study presents an underwater system based on protograph low-density parity check (P-LDPC) codes and orthogonal frequency division multiplexing (OFDM) for image transmission. The system proves a successful reconstruction of P-LDPC coded images with different levels of comparison. The performance of the proposed system is evaluated using nine objective measures such as bit error rate (BER) and peak signal to noise ratio (PSNR). Firstly, the proposed system performance is evaluated with different block lengths of P-LDPC code. Then, the implemented system shows a coding gain of approximately 1.75 dB for applying P-LDPC when compared to polar with cyclic redundancy check at 0.0001 BER. Additionally, image subjective assessment is obtained to demonstrate how the P-LDPC outweighs polar and turbo product codes in terms of estimated image quality. Lastly, further investigation is performed to study the effect of varying fast Fourier transform (FFT) size and cyclic prefix (CP) length on image reserved quality. The results show that the received image is better reconstructed for larger FFT sizes since that produce longer CP and symbol duration, and that in turn helps the system to combat the multipath fading introduced by the underwater channel.
