Validity of the Functional Classification of the Upper Extremities for Duchenne Muscular Dystrophy.

Objectives: Some upper-limb function assessments can evaluate treatments in the non-ambulatory stage of Duchenne muscular dystrophy (DMD). The Functional Classification of the Upper Extremities (FCUE) was developed for DMD in Japan. The FCUE is easier to use than the Performance of Upper Limb (PUL) and is more detailed than the Brooke Upper Extremity Scale. This study aimed to determine the concurrent validity of FCUE with other methods of assessment for DMD. Methods: This retrospective study reviewed the medical records of 39 boys with DMD from the National Center of Neurology and Psychiatry to evaluate the concurrent validity of the FCUE and PUL using non-parametric Spearman rank correlation (ρ). We also determined the concurrent validity of the Brooke Upper Extremity Scale and PUL for comparison. Results: The ρ value between the FCUE and PUL was -0.914 (P<0.001). The FCUE showed robust concurrent validity with the PUL. That correlation between the FCUE and Brooke Upper Extremity Scale gave a ρ value of -0.854 (P<0.001). Conclusions: The FCUE had a higher concurrent validity with the PUL than with the Brooke Upper Extremity Scale. The FCUE is considered a valid assessment tool of upper-limb function in boys with DMD. Selecting the best assessment method depends on the severity of the patient's condition and a balance between assessment accuracy and evaluation time.

Prognostic Factors Associated with Tumor Recurrence and Overall Survival in Soft Tissue Sarcomas of the Extremities in a Colombian Reference Cancer Center.

Introduction: Soft tissue sarcomas (STS) are low-incidence tumors whose clinical and histopathological factors are associated with adverse oncological outcomes. This study evaluated prognostic factors (PF) associated with tumor recurrence and overall survival (OS) in patients diagnosed with STS of the extremities, treated at the Instituto Nacional de Cancerología (INC), Bogotá, Colombia. Materials and Methods: An analytical observational study of a historical cohort was carried out, including patients diagnosed with STS and managed surgically in the Functional Unit for Breast and Soft Tissue Tumors of the INC from January 2008 to December 2018. Results: A total of 227 patients were included; 74.5% had tumors greater than 5 cm. Most patients (29.1%) were in stage IIIB at diagnosis. Age was associated with higher mortality (HR = 1.01; CI95%: 1-1.02; p = 0.048). Tumor persistence at admission to the INC (HR = 2.34; CI95%: 1.25-4.35; p = 0.007) and histologic grade III (HR = 5.36; CI95%: 2.29-12.56; p = <0.001) showed statistical significance in the multivariate analysis for recurrence of any type, as did the PFs associated with a higher risk of local recurrence (HR = 2.85; CI95%: 1.23-6.57; p = 0.014 and HR = 6.09; CI95%: 2.03-18.2; p = 0.001), respectively. Tumor size (HR = 1.03; CI95%: 1-1.06; p = 0.015) and histologic grade III (HR = 4.53; CI95%: 1.42-14.49; p = 0.011) were associated with a higher risk of distant recurrence. Conclusions: This cohort showed that in addition to histologic grade and tumor size, tumor persistence at the time of admission has an impact on disease recurrence, so STS should be managed by a multidisciplinary team with experience in this pathology in high-volume reference centers.

Neuromuscular Fitness Is Associated with Serve Speed in Young Female Tennis Players.

In tennis, the serve plays a key role in determining the success of a player. The speed of a serve is influenced by a multitude of interconnected skills and abilities. The objective of this study was to establish the correlation between the explosive strength of the throwing type, the grip strength and flexibility of the arms, and the shoulder girdle with the serve speed in young female tennis players. Additionally, the study aimed to develop a regression model that accurately predicts the serve speed by analyzing the interplay among these variables. The study was carried out on a group of 20 tennis players, who had an average age of 13.10 ± 0.74 years. Additionally, their height was recorded as 165.70 ± 4.90 cm, and their body mass was measured at 51.45 ± 5.84 kg. To assess the motor abilities of the upper extremities, four tests were used that aimed to measure the explosive strength of the throwing type; one test was for the strength of the hand and forearm muscles, and one test was for the flexibility of the arms and shoulder girdle. Of all the variables examined, the medicine ball throw shot put (MBTSP) (r = 0.75), overhead medicine ball throw (OMBT) (r = 0.70), and grip strength (GS) (r = 0.71) displayed a notable correlation with serve speed (p < 0.05). The results obtained from the multiple regression analysis indicate that the combination of selected predictors (MBTSP-medicine ball throw shot put, OMBT-overhead medicine ball throw and GS-grip strength) explained 75% of the variability in serve speed. Significantly, MBTSP surfaced as the predominant predictor, autonomously elucidating 51% of the variability in serve speed. The importance of improving the analyzed motor skills of young female tennis players to enhance their serve in terms of speed is emphasized by the findings of this research.

Current Outcomes Following Upper and Lower Extremity Arterial Trauma from the National Trauma Data Bank.

OBJECTIVE: The modern treatments of trauma have changed in recent years. We aim to evaluate the factors associated with limb salvage and mortality after extremity arterial trauma, especially with respect to the type of conduit utilized in revascularization. METHODS: The National Trauma Data Bank was queried to identify patients with upper and lower extremity (UE and LE) arterial injuries between 2016 - 2020. The patients were stratified by the types of arterial repair. The primary outcome was in-hospital mortality. RESULTS: 8,780 patients were found with 5,054 (58%) UE and 3,726 (42%) LE injuries. Eighty-three percent were men, and the mean age was 34 ± 15 years. Penetrating mechanism was the predominant mode of injury in both UEs and LEs (73% and 67%, respectively) with a mean injury severity score (ISS) of 14 ± 8. For UEs, the majority underwent primary repair (67%, p<0.001), while the remainder received either a bypass (20%) or interposition graft (12%). However, LEs were more likely to receive a bypass (52%, p<0.00001) than primary repair or interposition graft (34% and 14%, respectively). Compared to the extremely low rates of amputation and mortality among UE patients (2% for both), LE injuries were more likely to result in both amputation (10%, p<0.001) and death (6%, p<0.001). Notably, compared to primary repair, use of a prosthetic conduit was associated with a 6.7-fold increase in risk of amputation in UE and 2.4-fold increase in LE (p<0.0001 for both). Synthetic bypasses were associated with a nearly 3-fold increase in return to the OR in UE bypasses (p<0.05) and a 2.4-fold increase in return to the OR in LE bypasses (p<0.0001). CONCLUSIONS: In recent years, most extremity vascular trauma was due to penetrating injury with a substantial burden of morbidity and mortality. However, both limb salvage rates and survival rates have remained high. Overall, LE injuries more often led to amputation and mortality than UE injuries. The most frequently used bypass conduit was vein, which was associated with less risk of unplanned return to the OR and limb loss, corroborating current practice guidelines for extremity arterial trauma.

Diagnosis and treatment of deep vein thrombosis of the lower and upper limbs. 2024 recommendations of the thromboembolic disease group of the Spanish Society of Internal Medicine.

Deep vein thrombosis (DVT) of the limbs is a common disease and causes significant morbidity and mortality. It is frequently the prelude to pulmonary embolism (PE), it can recur in 30% of patients and in 25-40% of cases they can develop post-thrombotic syndrome (PTS), with a significant impact in functional status and quality of life. This document contains the recommendations on the diagnosis and treatment of acute DVT from the Thromboembolic Disease group of the Spanish Society of Internal Medicine (SEMI). PE and thrombosis of unusual venous territories (cerebral, renal, mesenteric, superficial, etc.) are outside its scope, as well as thrombosis associated with catheter and thrombosis associated with cancer, which due to their peculiarities will be the subject of other positioning documents of the Thromboembolic Disease group of the Spanish Society of Internal Medicine (SEMI).

Markerless gait analysis through a single camera and computer vision.

The assessment of gait performance using quantitative measures can yield crucial insights into an individual's health status. Recently, computer vision-based human pose estimation has emerged as a promising solution for markerless gait analysis, as it allows for the direct extraction of gait parameters from videos. This study aimed to compare the lower extremity kinematics and spatiotemporal gait parameters obtained from a single-camera-based markerless method with those acquired from a marker-based motion tracking system across a healthy population. Additionally, we investigated the impact of camera viewing angles and distances on the accuracy of the markerless method. Our findings demonstrated a robust correlation and agreement (Rxy > 0.75, Rc > 0.7) between the markerless and marker-based methods for most spatiotemporal gait parameters. We also observed strong correlations (Rxy > 0.8) between the two methods for hip flexion/extension, knee flexion/extension, hip abduction/adduction, and hip internal/external rotation. Statistical tests revealed significant effects of viewing angles and distances on the accuracy of the identified gait parameters. While the markerless method offers an alternative for general gait analysis, particularly when marker use is impractical, its accuracy for clinical applications remains insufficient and requires substantial improvement. Future investigations should explore the potential of the markerless system to measure gait parameters in pathological gaits.

Adverse Events Reported in Trials Assessing Manual Therapy to the Extremities: A Systematic Review.

Objective: This review aimed to describe the quality and comprehensiveness of adverse event (AE) reporting in clinical trials incorporating manual therapy (MT) as an intervention for extremity conditions using the Consolidated Standards of Reporting Trials (CONSORT)-Harms extension as the benchmark. The secondary aim was to determine whether the quality of AE reporting improved after the availability of the CONSORT reporting checklist. Design: Systematic review. Methods: A literature search was conducted using multiple databases to identify trials where MT was used to treat extremity conditions. Studies that reported AEs were identified and evaluated using the CONSORT-Harms extension. The frequency of trials reporting study AEs before and after the publication of the updated 2010 CONSORT statement was calculated, along with the categorization of how study AEs were reported. Results: Of the 55,539 studies initially identified, 220 trials met all inclusion criteria. Eighty trials (36.4%) reported AE occurrence. None of the studies that reported AEs adhered to all 10 criteria proposed by the 2010 CONSORT-Harms extension. The most commonly reported criterion was number four, which clarified how AE-related information was collected (30% of trials). The least reported criterion was number six, which describes the participant withdrawals for each arm due to AEs and the experience with the allocated treatment (1.3% of trials). The nomenclature used to describe AEs varied substantially. Fifty-nine of 76 trials (33.3%) were published after the updated CONSORT Harms-checklist was available, compared to 21 of 44 trials (46.7%) published before it was available. Conclusion: Reporting of AEs in trials investigating MT for extremity conditions is poor. Every included trial lacked adherence to all 10 criteria proposed by the CONSORT-Harms Extension. The quality and comprehensiveness of AE reporting did not improve after the most recent CONSORT update recommending AE reporting. Clinicians must obtain informed consent before performing any intervention, including MT, which requires disclosing potential risks, which could be better known with improved tracking, analyzing, and reporting of AEs. The authors recommend improved adherence to best practices for adequately tracking and reporting AEs in future MT trials.

Comparison of the Pre-Established and Finally Selected Treatment Strategies for Endovascular Treatment in Femoropopliteal Artery Lesions.

This study aimed to compare lower limb events associated with preplanned and finally selected treatment strategies-the validity and usefulness of the physician-chosen strategy were verified.We examined the data of 1003 patients in the registry of multicenter endovascular treatment for superficial femoral and popliteal artery disease study and prospectively enrolled patients who underwent endovascular treatment (EVT) of the femoropopliteal (FP) artery between February 2017 and June 2018 from 67 Japanese institutes. The outcome measures were major adverse limb events (MALE) and target vessel revascularization.The EVT strategies were classified into balloon angioplasty-alone (37.3%), primary stenting (26.7%), and provisional stenting (36.0%) groups. In the initial strategy analysis for the balloon angioplasty-alone, primary stenting, and provisional stenting groups, two-year rates of freedom from MALE (95% confidence interval) were 0.680 (0.620-0.732), 0.754 (0.688-0.808), and 0.798 (0.746-0.840), respectively. Additionally, the rate of MALE was significantly higher among patients in the balloon angioplasty-alone group than among those in the primary or provisional stenting groups in the initial strategy analysis (P = 0.007). Changes in treatment strategy were more frequent in the primary stenting group than in the other groups. Furthermore, the rate of MALE did not significantly differ among the three groups in the final strategy analysis (P = 0.56).Limb outcomes for the final applied strategy did not differ among the three strategies. Additionally, the physician's selection bias was mostly appropriate in the EVT of the FP artery.

A prognostic nomogram for recurrence survival in post-surgical patients with varicose veins of the lower extremities.

Varicose veins of the lower extremities (VVLEs) are prevalent globally. This study aims to identify prognostic factors and develop a prediction model for recurrence survival (RS) in VVLEs patients after surgery. A retrospective analysis of VVLEs patients from the Third Hospital of Nanchang was conducted between April 2017 and March 2022. A LASSO (Least Absolute Shrinkage and Selection Operator) regression model pinpointed significant recurrence predictors, culminating in a prognostic nomogram. The model's performance was evaluated by C-index, receiver operating characteristic (ROC) curves, calibration plots, and decision curve analysis (DCA). The LASSO regression identified seven predictors for the nomogram predicting 1-, 2-, and 5-year RS. These predictors were age, body mass index (BMI), hypertension, diabetes, the Clinical Etiological Anatomical Pathophysiological (CEAP) grade, iliac vein compression syndrome (IVCS), and postoperative compression stocking duration (PCSD). The nomogram's C-index was 0.716, with AUCs (Area Under the Curve scores) of 0.705, 0.725, and 0.758 for 1-, 2-, and 5-year RS, respectively. Calibration and decision curve analyses validated the model's predictive accuracy and clinical utility. Kaplan-Meier analysis distinguished between low and high-risk groups with significant prognostic differences (P < 0.05). This study has successfully developed and validated a nomogram for predicting RS in patients with VVLEs after surgery, enhancing personalized care and informing clinical decision-making.

[Endovascular treatment of deep vein thrombosis of the upper extremities]. / Endovaskulyarnoe lechenie trombozov glubokikh ven verkhnikh konechnostei.

OBJECTIVE: To improve the results of treatment of deep vein thrombosis of the upper extremities sing endovascular technologies. MATERIAL AND METHODS: We analyzed safety and effectiveness of treatment in 24 patients with deep vein thrombosis of the upper extremities. All ones were divided into 2 homogeneous groups by 12 people each. In the first group, conventional anticoagulation was performed. In the second group, we used additional regional catheter thrombolysis with alteplase and, if necessary, venous stenting or balloon angioplasty for residual stenosis. Patients received apixaban at baseline and throughout 6 postoperative months. After 12 months, we performed ultrasound and clinical examination to identify deep vein patency and venous outflow disorders. Vein recanalization was evaluated as follows: <50% - minimal, 50-99% - partial, 100% - complete. The quality of life of patients was studied using the SF-36 questionnaire. RESULTS: In the first group, we observed complete vein recanalization in 25% of cases, partial - in 33%, minimal - in 41% of cases; in the second group - 83.3% and 16.7% of patients, respectively. In the first group, clinical manifestations of venous outflow disorders were absent in 25% of patients, mild disorders - 25%, moderate - 8.3%, severe - 41.7% of patients. In the second group, venous outflow was not impaired in 83.7% of patients, mild violations occurred in 16.7% of patients. In the first group, physical health was equal to 44.2±1.7 scores, psychological health - 49.3±2.3 scores; in the second group - 69.3±5.7 and 71.3±5.4 scores, respectively. CONCLUSION: Endovascular treatment improved postoperative outcomes.

Clinicopathological Profile and Survival Outcomes in Patients with Localised Extremity Synovial Sarcomas.

AIMS: Synovial sarcoma is a rare but aggressive variant of soft-tissue sarcoma. Literature is sparse and reported mostly from the West. We analysed the clinical profiles and prognostic factors of extremity synovial sarcoma patients in order to study their clinical journey. MATERIALS AND METHODS: This was a retrospective analysis. All patients with extremity synovial sarcoma treated between 1992 and 2020 were included. Patients with metastases at presentation were excluded. A descriptive analysis of demographic and clinicopathological features of patients undergoing limb salvage surgery (LSS) or amputation was carried out. Overall survival and disease-free survival were calculated for the entire cohort as well as for the LSS and amputation groups. Factors prognostic for survival were identified. RESULTS: In total, 157 patients had localised extremity synovial sarcoma. Predominantly, young adults (median 31 years) and males (61%) were affected. Over 70% of patients presented after recurrence or unplanned surgeries. Sixty-seven per cent of tumours were >5 cm, 69% were deep and 23% involved bone. The limb salvage rate was 64%. In the LSS group, adjuvant radiotherapy and chemotherapy were given to 72% and 68% of patients, respectively. In the amputation group, 72% of patients received adjuvant chemotherapy. In a median follow-up of 59 months, 39.4% of patients had recurrences, the majority (61.2%) were systemic. Five-year overall survival and disease-free survival were 53.4% and 49.8%, respectively. Overall survival was 63.9% and 29.7% in the LSS and amputation groups, respectively. On multivariate analysis, tumour size, depth, omission of radiotherapy and bone invasion were found to be the adverse prognostic factors. CONCLUSION: This is one of the largest studies on extremity synovial sarcoma. Mostly males and young adults were affected. The limb salvage rate was 64%, despite most being referred after unplanned surgery. Almost 70% of patients received radiotherapy and chemotherapy. Overall survival was inferior in the amputation group. Tumour size >5 cm, depth and bone invasion were negative, whereas adjuvant radiotherapy was a positive prognostic factor for survival. Chemotherapy had no impact on survival.

A pilot study of p53 immunohistochemistry in atypical squamous lesions, using a vulvar scoring system.

BACKGROUND: Histopathologic overlap between cutaneous squamous cell carcinoma (cSCC) and its indolent mimics likely leads to the overdiagnosis of cSCC. OBJECTIVE: To perform a pilot study of the p53 immunohistochemical scoring system developed on vulvar squamous lesions in cSCC. METHODS: The consistency and reliability of p53 immunostaining using a scoring system developed on vulvar cases, as compared with TP53 genomic sequencing, was studied in an initial cohort of 28 cutaneous cases. p53 labeling was further assessed in an additional 63 cases of atypical squamous lesions, including 20 atypical squamous lesions classified by the authors as benign, 22 cases diagnosed as cSCC without high-risk features, and 21 cases of high-risk cSCC (cSCC-HR). RESULTS: The concordance of p53 labeling and TP53 sequencing was 82.1%. Four positive patterns of p53 mutation were identified: basal, parabasal/diffuse, null, and cytoplasmic. p53 positivity in atypical, benign squamous lesions (10%) was significantly lower than that of low-risk cSCC (63.6%, p = 0.0004) or cSCC-HR (90.5%, p < 0.0001). p53 positivity in low-risk cSCC versus cSCC-HR was not statistically significant (p = 0.07). CONCLUSION: p53 Labeling may be a helpful biomarker to support the diagnosis of cSCC and distinguish cSCC from atypical but benign mimics.

Artificial intelligence diagnostic model for multi-site fracture X-ray images of extremities based on deep convolutional neural networks.

Background: The rapid and accurate diagnosis of fractures is crucial for timely treatment of trauma patients. Deep learning, one of the most widely used forms of artificial intelligence (AI), is now commonly employed in medical imaging for fracture detection. This study aimed to construct a deep learning model using big data to recognize multiple-fracture X-ray images of extremity bones. Methods: Radiographic imaging data of extremities were retrospectively collected from five hospitals between January 2017 and September 2020. The total number of people finally included was 25,635 and the total number of images included was 26,098. After labeling the lesions, the randomized method used 90% of the data as the training set to develop the fracture detection model, and the remaining 10% was used as the validation set to verify the model. The faster region convolutional neural networks (R-CNN) algorithm was adopted to construct diagnostic models for detection. The Dice coefficient was used to evaluate the image segmentation accuracy. The performances of detection models were evaluated with sensitivity, specificity, and area under the receiver operating characteristic curve (AUC). Results: The free-response receiver operating characteristic (FROC) curve value was 0.886 and 0.843 for the detection of single and multiple fractures, respectively. Additionally, the effective identification AUC for all parts was higher than 0.920. Notably, the AUC for wrist fractures reached 0.952. The average accuracy in detecting bone fracture regions in the extremities was 0.865. When analyzing single and multiple lesions at the patient level, the sensitivity was 0.957 for patients with multiple lesions and 0.852 for those with single lesions. In the segmentation task, the training set (the data set used by the machine learning model to train and learn) and the validation set (the data set used to evaluate the performance of the model) reached 0.996 and 0.975, respectively. Conclusions: The faster R-CNN training algorithm exhibits excellent performance in simultaneously identifying fractures in the hands, feet, wrists, ankles, radius and ulna, and tibia and fibula on X-ray images. It demonstrates high accuracy, low false-negative rates, and controllable false-positive rates. It can serve as a valuable screening tool.

Comparison of ground reaction force among stride types in baseball pitching.

This study aims to investigate the different ground reaction force (GRF) characteristics from different stride types. This study included 30 Taiwanese elite college and professional baseball pitchers. Each pitcher was classified into one of the following stride types: tall and fall (TF), dip and drive (DD), or mixed (MX). Our findings indicated that DD pitchers pressed their bodies forward earlier than TF pitchers. In contrast, the GRF of the pivot leg of TF pitchers increased slowly in the first half of the stride phase and continued to increase even after the stride leg touched the ground. This type of continuous pressing in TF was different from that in DD and MX pitchers, which decreased rapidly into the arm-cocking & acceleration phases. We conclude that the lower extremities were used differently by TF, DD and MX pitchers. This information could serve as a training guideline for coaches and pitchers to enhance training effectiveness, while simultaneously lowering injury risks.

Antenatal description of large 4q13.2q21.23 deletion and outcomes.

BACKGROUND: 4q21 microdeletion syndrome is an emergent non-recurrent genomic disorder characterized by facial dysmorphy, progressive growth retardation, severe intellectual deficit, and absent or severely delayed speech. Deletions occur in clusters along 4q interstitial or terminal regions. 4q chromosomal aberrations are variable in type, size, and breakpoint. Genotype-phenotype correlation is a challenging task. The recurrent antenatal feature associated a posteriori with this syndrome is intrauterine growth retardation. There are very few precise antenatal descriptions of this syndrome. METHODS: We report here the first antenatal history of one of the largest deletion of this region. RESULTS: Our case harbored a 16.9 Mb deletion encompassing 135 protein coding genes including 20 OMIM morbid genes involved in neurological and cognitive abilities. Those breakpoints overlap two clusters of described microdeletion syndromes of cytogenetic band 4q13 and 4q21. CONCLUSION: From the end of the second trimester, set of call signs associated with this syndrome can be completed by: excess of amniotic fluid, mild growth retardation, short long bones, bony anomalies of the extremities, and bulging cheeks. So, emphasis should be placed on the examination of the extremities, and the face during the routine targeted prenatal ultrasound.

Rare deep vein thrombosis in pregnancy and puerperium 3 case series; upper extremities vein thrombosis, ovarian vein thrombosis, portal and superior mesenteric vein thrombosis.

Pregnancy induces a hypercoagulable state, elevating thrombosis risk by 5-6 times compared to non-pregnant conditions. Predominantly affecting the left lower extremity due to anatomical and hematological factors, deep vein thrombosis can escalate into pulmonary embolism, impacting mortality. The authors aim to report rare incidents of thrombosis beyond the norm, including upper extremity vein thrombosis, right ovarian vein thrombosis, and portal vein and superior mesenteric vein thrombosis, highlighting their significance. Obstetricians should be mindful that thrombosis can occur not only in the lower extremities but also in other areas. Especially when symptoms such as fever unresponsive to antibiotics, atypical pain, and an abnormally high C-reactive protein level are present. Considering the possibility of a rare thrombosis is crucial. Understanding these less common thrombotic events during pregnancy and the postpartum period can contribute to the improvement of timely diagnosis and management strategies.

New interpretation of "Miu Ci". / "缪刺"新识.

Based on the record of Miu Ci theory from Huangdi Neijing (The Yellow Emperor's Internal Classic), and incorporating the relevant discussions of medical scholars from various dynasties, this article interprets and analyzes the Miu Ci technique, the points to be needled, and the diseases can be treated. The following innovative understandings are proposed： 1) The original meaning of "Miu" in Miu Ci is "to prick in a different way from the meridians (needle the major collaterals)", not "needle left and right interchangeably". Needle left and right interchangeably is not a necessary operation in Miu Ci. 2) The stimulation sites of Miu Ci are the "four extremities" of the human body, referred to as the "major collaterals of qi", and the nail bed of the four extremities is not equivalent to the commonly reco-gnized "Jing-well points". 3) Miu Ci can treat critical illnesses, not just limited to musculoskeletal pain or mild conditions at the early stage of a disease. 4) Miu Ci is not equivalent to Luo Ci needling (pricking bloodletting therapy).

Geo-ecological, shoreline dynamic, and flooding impacts of Cyclonic Storm Mocha: A geospatial analysis.

This research comprehensively assesses the aftermath of Cyclonic Storm Mocha, focusing on the coastal zones of Rakhine State and the Chittagong Division, spanning Myanmar and Bangladesh. The investigation emphasizes the impacts on coastal ecology, shoreline dynamics, flooding patterns, and meteorological variations. Employed were multiple vegetation indices-Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), Modified Vegetation Condition Index (mVCI), Disaster Vegetation Damage Index (DVDI), and Fractional Vegetation Cover (FVC)-to evaluate ecological consequences. The Digital Shoreline Assessment System (DSAS) aided in determining shoreline alterations pre- and post-cyclone. Soil exposure and flood extents were scrutinized using the Bare Soil Index (BSI) and Modified Normalized Difference Water Index (MNDWI), respectively. Additionally, the study encompassed an analysis of microclimatic variables, comparing meteorological data across pre- and post-cyclone periods. Findings indicate significant ecological impacts: an estimated 8985.46 km2 of dense vegetation (NDVI >0.6) was adversely affected. Post-cyclone, there was a discernible reduction in EVI values. The mean mVCI shifted negatively from -0.18 to -0.33, and the mean FVC decreased from 0.39 to 0.33. The DVDI underscored considerable vegetation damage in various areas, underscoring the cyclone's extensive impact. Meteorological analysis revealed a 245 % increase in rainfall (20.22 mm on May 14, 2023 compared to the May average of 5.86 mm), and significant increases in relative humidity (14 %) and wind speed (205 %). Erosion was observed along 74.60 % of the studied shoreline. These insights are pivotal for developing comprehensive strategies aimed at the rehabilitation and conservation of critical coastal ecosystems. They provide vital data for emergency response initiatives and offer resources for entities engaged in enhancing coastal resilience and protecting local community livelihoods.

The Effect of Maternal Lower Limb Compression on Amniotic Fluid Index, Uteroplacental Perfusion, and Fetal Blood Flow in Isolated Oligohydramnios.

INTRODUCTION: The aim of this study was to examine the efficacy of pneumatic compression of the maternal lower extremities in increasing the amniotic fluid index (AFI) in pregnancies complicated by isolated oligohydramnios. METHODS: Women with isolated oligohydramnios (AFI <5 cm) at 32-41 weeks of pregnancy were connected to a sequential compression device for 60 min. Prior and after the application, AFI and the pulsatility index (PI) of a number of arteries were measured. RESULTS: The median (interquartile range) maternal age of the 21 women included was 29 years (26.50-32.00), the median parity was 1 (1-2), and the median gestational age at intervention was 37.60 weeks (37.00-39.40). The median AFI increased after the application from 4.00 (3.62-4.50) to 6.08 cm (4.90-7.03) (p < 0.001). The median PI of the fetal renal artery decreased from 2.30 (2.01-2.88) to 2.26 (1.68-2.71) (p = 0.01). The hourly fetal urine production did not increase. Changes were not significant in the PI of the umbilical artery, the middle cerebral artery, and the bilateral uterine arteries. CONCLUSION: Short-term activation of pneumatic compression on maternal lower extremities could increase the AFI in women with isolated oligohydramnios.

Effect of intranasal sufentanil on acute post-traumatic pain in the emergency department: a randomised controlled trial.

BACKGROUND: Intranasal sufentanil is a potent opioid which can be used in patients with traumatic injuries presenting to the ED. Although previous studies have demonstrated the superiority of intranasal sufentanil over intravenous morphine in terms of pain relief, its clinical superiority in patients with traumatic injuries receiving adequate multimodal analgesia with acetaminophen and non-steroidal anti-inflammatory drugs is uncertain. We compared pain relief offered by intranasal sufentanil with that offered by oral and intravenous opioids in patients with acute traumatic injuries also receiving a specified regimen of non-opioid treatment. METHODS: In this single-centre, open-label, parallel-group, randomised controlled superiority trial conducted between January 2020 and February 2022, trauma patients presenting to the ED with a pain score of ≥7 on a visual analogue scale (VAS) were randomised to receive either intranasal sufentanil or other oral/intravenous opioids alongside oral/intravenous acetaminophen and non-steroidal anti-inflammatory drugs. The primary outcome was reduction in VAS score 15-20 min after randomisation. RESULTS: An intention-to-treat analysis included 170 out of 205 patients screened for inclusion. The intranasal sufentanil group (83 patients) showed a significantly greater reduction in pain when compared with the oral/intravenous opioid group (87 patients) 15-20 min after randomisation (reduction in VAS score 3.0 (IQR 1.7-5.0) vs 1.5 (IQR 0.9-3.0); p<0.001). Similarly, a greater reduction in pain was observed in the intranasal sufentanil group 60 min after randomisation (5.0 (IQR 3.0-7.0) vs 3.0 (IQR 2.0-5.3); p<0.001). However, side effects were more frequent in the intervention group (71.1% vs 23%; p<0.001). CONCLUSIONS: Intranasal sufentanil was associated with more effective pain relief than oral/intravenous opioids in patients with traumatic injuries treated with coanalgesia. Intranasal sufentanil could be considered for the management of pain in patients with traumatic injuries associated with severe pain. TRIAL REGISTRATION NUMBER: NCT04137198.
