Модели восприятия амбивалентного Другого в условиях негативного пре-стимула

<p>The effects of framing with pre-stimulus information on the target object assessment were simulated in the perception of self-presentation video interview. Non-target personages of extremely positive and negative personal valence were presented as pre-stimuli. Two path models were built: the first one (Attitude Model) reproduced the structural logic of the attitude formation, and the second one (TraitsтModel) — the logic of dispositional traits perception. The sample consisted of 394 students from 17 to 27 years old (M = 20.06, SD = 1.24). It was found that the shifts in the target object's scores were occurred according to the contrast effect, however, this effect was triggered only by the negative pre-stimulus. In the Attitude Model, the primary “target” of the negative pre-stimulus is the cognitive component of the attitude. Slightly changing towards growth, it caused an avalanche-like positive shift in the emotional and behavioral components. In the Traits Model, the shift in the perception of personality traits was also occurred according to the principle of contrast. Negative pre-stimulus had a direct impact on the perception of Agreeableness and Extraversion, which, in turn, mediated the perception of Conscientiousness and Openness to experience. The results obtained could be used to create directed perceptual effects in the process of pedagogical, media or therapeutic influence.</p>

Effect of different degrees of primary varus knee on short-term effectiveness of anterior cruciate ligament reconstruction

To investigate whether different degrees of primary varus knee affect joint function and stability in patients undergoing anterior cruciate ligament (ACL) reconstruction. A clinical data of 160 patients with primary varus knee, who were admitted between January 2020 and December 2021 and met the selection criteria, was retrospectively analyzed. All patients underwent primary ACL reconstruction using autologous single-bundle hamstring tendon. Patients were divided into three groups based on the hip-knee-ankle angle (HKA): group A (64 patients with HKA 0°-3°), group B (55 patients with HKA 3°-6°), and group C (41 patients with HKA 6°-9°). Except for the significant difference in HKA among the three groups ( P<0.05), baseline data such as age, gender, affected side, body mass index, interval between injury and operation, Kellgren-Lawrence grading, posterior tibial slope, proportion of combined meniscal injuries, Tegner score, Lysholm score, and International Knee Documentation Committee (IKDC) objective score, anterior drawer test, Lachman test, pivot shift test, and the results of KT1000 (side-to-side difference, SSD) showed no significant difference ( P>0.05). At last follow-up, joint stability was assessed through the anterior drawer test, Lachman test, pivot shift test, and SSD; joint function was evaluated using the Tegner score, Lysholm score, and IKDC objective score. All incisions in the three groups healed by first intention after operation. All patients were followed up 24-31 months, with an average of 26 months; there was no significant difference in the follow-up time among the three groups ( Z=0.675, P=0.714). At last follow-up, the knee stability and functional assessment indicators in each group significantly improved when compared to preoperative ones ( P<0.05); there was no significant difference among the three groups ( P>0.05) in terms of the anterior drawer test, Lachman test, pivot shift test, IKDC objective scores, and the changes of the Lysholm scores and Tegner scores. The Kellgren-Lawrence grading and HKA at last follow-up were consistent with preoperative results in the three groups. Varying degrees of primary varus knee do not affect early knee joint stability and functional recovery after ACL reconstruction, and there is no significant difference in effectiveness between different degrees of varus knee.

Semi-Supervised One-Stage Object Detection for Maize Leaf Disease

Maize is one of the most important crops globally, and accurate diagnosis of leaf diseases is crucial for ensuring increased yields. Despite the continuous progress in computer vision technology, detecting maize leaf diseases based on deep learning still relies on a large amount of manually labeled data, and the labeling process is time-consuming and labor-intensive. Moreover, the detectors currently used for identifying maize leaf diseases have relatively low accuracy in complex experimental fields. Therefore, the proposed Agronomic Teacher, an object detection algorithm that utilizes limited labeled and abundant unlabeled data, is applied to maize leaf disease recognition. In this work, a semi-supervised object detection framework is built based on a single-stage detector, integrating the Weighted Average Pseudo-labeling Assignment (WAP) strategy and AgroYOLO detector combining Agro-Backbone network with Agro-Neck network. The WAP strategy uses weight adjustments to set objectness and classification scores as evaluation criteria for pseudo-labels reliability assignment. Agro-Backbone network accurately extracts features of maize leaf diseases and obtains richer semantic information. Agro-Neck network enhances feature fusion by utilizing multi-layer features for collaborative combinations. The effectiveness of the proposed method is validated on the MaizeData and PascalVOC datasets at different annotation ratios. Compared to the baseline model, Agronomic Teacher leverages abundant unlabeled data to achieve a 6.5% increase in mAP (0.5) on the 30% labeled MaizeData. On the 30% labeled PascalVOC dataset, the mAP (0.5) improved by 8.2%, demonstrating the method’s potential for generalization.

Learning sparse feature representation for blind quality assessment of night-time images

Capturing Night-Time Images (NTIs) with high-quality is quite challenging for consumer photography and several practical applications. Thus, addressing the quality assessment of night-time images is urgently needed. Since there is no available reference image for such images, Night-Time image Quality Assessment (NTQA) should be done blindly. Although Blind natural Image Quality Assessment (BIQA) has attracted a great deal of attention for a long time, very little work has been done in the field of NTQA. Due to the capturing conditions, NTIs suffer from various complex authentic distortions that make it a challenging field of research. Therefore, previous BIQA methods, do not provide sufficient correlation with subjective scores in the case of NTIs and special methods of NTQA should be developed. In this paper we conduct an unsupervised feature learning method for blind quality assessment of night-time images. The features are the sparse representation over the data-adaptive dictionaries learned on the image exposure and gradient magnitude maps. Having these features, an ensemble regression model trained using least squares gradient boosting scheme predicts high correlated objective scores on the standard datasets.

Development and validation of a technical skill score for internal version and total breech extraction of the second twin: An interventional prospective study.

To develop and test an Objective Structured Assessment of Technical Skills (OSATS) score for the internal version and total breech extraction of the second twin if in a non-engaged cephalic position. This prospective interventional study took place in a tertiary obstetrics department in France. An objective scoring system was developed, and a standardized simulation scenario was set up. Score evaluation was blinded and analyzed according to group and number of past successful vaginal twin deliveries in real life. A satisfaction evaluation was performed, based on the "Student Design Scale" questionnaire. Simulation was performed on 33 participants in three groups: novice group (15 first- and second-year residents), intermediate group (11 third- to sixth-year residents), and expert group (seven senior obstetricians). The total score obtained by experts was higher than that of the intermediate group (P = 0.001), which was higher than that of the novice group (P < 0.001). In the intermediate group, no correlation was found between OSATS score and number of past successful vaginal twin deliveries. Participants' satisfaction was excellent. The OSATS score developed was reliable and valid to evaluate an internal version and a total breech extraction of the second twin, and to differentiate novice, intermediate, and expert practitioners.

Also, in Functional knee score in each of Pre- and Post-operative was 51.39±8.67, compared to 73.80±7.75 respectively. 4 patients (8.9%) had complications out of them 3 patients (6.7%) had superficial infection and 1 patient (2.2%) had acute coronary syndrome. Conclusion With careful preoperative patient selection bilateral Simultaneous total knee arthroplasty can be safe with low mortality and complication rates.

P-240 Is the intelligent Data Analysis Score (iDAScore) a reliable tool to predict pregnancy? Our center’s experience

Abstract Study question Is the intelligent Data Analysis Score (iDAScore) reliable in predicting a positive pregnancy test, clinical pregnancy and miscarriage rate after single vitrified-warmed blastocyst transfer (SVBT)? Summary answer There is a significant increase in positive pregnancy test and clinical pregnancy rates as iDAScore increases. The miscarriage rate is lower with increased iDAScore. What is known already With the improvement of assisted reproductive technology (ART), elective single embryo transfer has become a standard. Optimizing embryo selection is a major challenge to increase reproductive outcomes. The Gardner embryo grading system is widely adopted for the evaluation of blastocyst quality, but this tool is subject to inter- and intra-variability. In recent years, artificial intelligence has found diverse applications in healthcare. Based on time-laps sequences of &amp;gt; 180’000 developing embryos, iDAScore is a new deep-learning model for objective and standardized blastocyst scoring. However, its reliability in predicting pregnancy and miscarriage rates remains unknown. Study design, size, duration This monocentric retrospective pilot study was conducted from May 2023 to December 2023. A total of 206 homologous SVBT cycles from 206 patients were analyzed (one patient, one cycle). Exclusion criteria included: cycles involving preimplantation genetic testing, multiple and/or fresh blastocyst transfer, and blastocysts obtained after testicular sperm extraction. All vitrified-warmed blastocysts were scored using iDAScore version 1.0 model, ranging from 1 – 9.9. Participants/materials, setting, methods Scores were stratified into 3 groups: high-score (9.9 – 7.7), medium-score (7.6 – 5.5) and low-score (5.4 – 3.1). For each group, positive pregnancy test, clinical pregnancy and miscarriage rates were analyzed. SVBT cycles were then stratified into four maternal age groups (&amp;lt; 35, 35-37, 38-40, &amp;gt;41 years) and the same outcomes were analyzed. χ2 was used for statistics analysis. Main results and the role of chance Mean maternal age was 36.8 ± 4.9. Among the 206 vitrified-warmed blastocysts, 122 were scored as high-score, 57 as medium-score and 27 as low-score. Positive pregnancy test rate was significantly higher with increased iDAScore with 58% in the high-score group, 36.8% in the medium-score group and 17% in the low-score group (p &amp;lt; 0.0001). Clinical pregnancy rate, defined as the visualization of a fetal heartbeat at ultrasound scan, was also significantly higher with increased iDAScore, with 51.6% in the high-score group, 31.6% in the medium-score group and 17% in the low-score group (p &amp;lt; 0.0001). The miscarriage rate was lower with increased iDAScore, with 8.1% in the high-score group, 16.6% in the medium-score group and 50% in the low-score group, but this difference was not statistically significative (p 0.032). When adjusted to age group however, the miscarriage rate was found to be significantly lower in the high-score group when compared to the medium-score group (p &amp;lt; 0.0001); statistical analysis was not achieved in the low-score group due to the small sample size. Limitations, reasons for caution The major limitation of our study is its small sample size. Data collection is ongoing, to increase the study power. Additionally, many other factors, such as genetic, hormonal, metabolic and/or immunological, may play a role in achieving pregnancy. Wider implications of the findings Our results indicate that iDAScore may be a strong predictor of pregnancy and could be used as a complementary tool to the Gardner embryo grading system in the decision-making process of which blastocyst to transfer.

Surgical Cholecystectomy Score (SCS) for grading the difficulty of laparoscopic cholecystectomy.

Laparoscopic cholecystectomy (LC) is the standard of care for symptomatic gall stone disease. A good scoring system is necessary to standardize the reporting. Our aim was to develop and validate an objective scoring system, the Surgical Cholecystectomy Score (SCS) to grade the difficulty of LC. The study was conducted in a single surgical unit at a tertiary care hospital in two phases from January 2017 to April 2021. Retrospective data was analysed and the difficulty of each procedure was graded according to the modified Nassar's scoring system. Significant preoperative and intraoperative data obtained was given a weightage score. In phase II, these scores were validated on a prospective cohort. Each procedure was classified either as easy, moderately difficult or difficult. A univariate analysis was performed on the data followed by a multivariate regression analysis. Bidirectional stepwise selection was done to select the most significant variables. The Beta /Schneeweiss scoring system was used to generate a rounded risk score. Data of 800 patients was retrieved and graded. 10 intraoperative parameters were found to be significant. Each variable was assigned a rounded risk score. The final SCS range for intraoperative parameters was 0-15. The scoring system was validated on a cohort of 249 LC. In the final scoring, cut off SCS of > 8 was found to correlate with difficult procedures. Score of < 2 was equivalent to easy LC. A score between 2 and 8 indicated moderate difficulty. The area under ROC curve was 0.98 and 0.92 for the intraoperative score indicating that the score was an excellent measure of the difficulty level of LCs. The scoring system developed in this study has shown an excellent correlation with the difficulty of LC. It needs to be validated in different cohorts and across multiple centers further.

Immediate Latissimus Dorsi Flap Reconstruction: Assessing Aesthetic Outcomes Following Mastectomy in Breast Cancer Patients.

Breast Cancer has now become the leading cause of cancer-related deaths among women. In a traditional radical mastectomy, there can be complications that may affect the physiological characteristics of the breast and subsequently cause profound psychological stress to the patients. Hence, latissimus dorsi (LD) flap reconstruction provides an aesthetic approach in patients undergoing mastectomy. The goal is to maximize the flap's soft tissue coverage while minimizing the magnitude of donor site defect and complication. A prospective observational study was conducted in the Department of General Surgery, Safdarjung Hospital, New Delhi, India, where 30 breast cancer patients were enrolled and had undergone mastectomy with immediate LD flap reconstruction. Cosmetic assessments using BREAST-Q questionnaires were conducted postoperatively at various intervals starting from postoperative day one, week two, and week six. The subjective evaluation was done by the patient, while a blinded nurse and surgeon did the objective assessment. The majority (n=23, 76.7%) were aged 31-50 years. Initial postoperative BREAST-Q scores declined but significantly improved by week six, attributed to gradual wound healing over time, resulting in improved breast shape and contour. The objective scoring done by the blinded surgeon and nurse improved at six weeks compared to two weeks postoperatively. Almost similar outcomes were observed between preoperative and six-week postoperative scores with a significant overall p-value of <0.001. No significant statistical differences were noted between blinded surgeons and nurses for objective scoring. The rising trend of breast cancer in younger demographics emphasizes the importance of balancing cosmetic satisfaction with oncological outcomes. Immediate LD flap breast reconstruction provides a reliable means for soft tissue coverage with acceptable perioperative morbidities for patients undergoing mastectomy. Complication rates were acceptable, with donor site seroma, surgical site infection (SSI), and shoulder weakness among them. They could be prevented or treated (prolonged drain in situ, quilting sutures, and seroma aspiration) or resolved with time (SSI and shoulder function).

Preoperative Medial Meniscus Extrusion on Magnetic Resonance Imaging Is Associated With a Tendency Toward Varus Shifting of Open-Wedge High Tibial Osteotomy: A Minimum 5-Year Follow-Up Study

PurposeTo investigate serial changes in postoperative alignment over 5 years after open-wedge high tibial osteotomy (OWHTO) and to identify risk factors associated with alterations in the postoperative weight-bearing line WBL ratio. MethodsPatients who underwent OWHTO during 2011–2017 were retrospectively reviewed. Inclusion criteria were (1) follow-up duration ≥5 years and (2) serial postoperative long-standing hip-to-ankle radiographs to evaluate alignment alterations. The WBL ratio was measured preoperatively and at 3 months, 6 months, 1 year, and 5 years postoperatively to evaluate serial changes. Alterations in the WBL ratio were analyzed using a linear mixed model, considering potential risk factors including International Cartilage Repair Society (ICRS) grades of each compartment, and medial meniscus extrusion (≥3 mm). Clinical outcomes were assessed using the Knee Society (KS) objective and functional scores, and the correlations between clinical outcomes and alignment alteration were examined. ResultsA total of 78 knees were investigated. During the study period, the overall WBL ratio decreased by 5.5 ± 7.2%, signifying varus shifting, from 58.6 ± 11.5% at 3 months post-surgery to 51.5 ± 12.7% at 5 years post-surgery. Based on univariate regression analyses, ICRS grade of the medial compartment and medial meniscus extrusion were included in a linear mixed model regarding alignment alteration. The model identified medial meniscus extrusion as a significant risk factor after adjusting for time (p <0.001). Medial meniscus extrusion also had a significant interaction with time (p <0.001), indicating greater alignment alteration in cases of medial meniscus extrusion. The extrusion was noted in 68 out of 78 knees. ConclusionIn the midterm following OWHTO, the overall alignment had a tendency toward varus shifting. A linear mixed model found that preoperative medial meniscus extrusion on magnetic resonance imaging is associated with the tendency.

Comparative Evaluation of Pain Perception with Conventional and Septoject XL Needle in 6-8-year-old Children: A Randomized Controlled Trial.

To evaluate and compare pain perception with Septoject XL and conventional needles in 6-8 years old children. In this split-mouth randomized controlled trial, a single-blinded study, 24 children (6-8 years) were assigned at random to receive the local anesthetic (LA) injection for treatment needs either with Septoject XL or conventional needle for the first visit in one of the quadrants, while during the second visit in a different quadrant with the other one. Children's pain levels were assessed during each visit using an objective sound eye motor (SEM) scale and subjective Wong-Baker faces rating scale (FRS). The mean objective score rating using SEM for the conventional needle (3.8 ± 2.35) and Septoject XL needle (3.3 ± 2.01) was not found to be statistically significant among the two study groups Septoject XL or conventional needle (Z score-0.996, p = 0.3). Using the Wilcoxon test, the mean subjective rating score was not found to be statistically significant among the two study groups [Z score = 0.636 and p-value = 0.524, nonsignificant (NS)]. In the gender-wise comparison of male (n =15), (6.8667 ± 91548) and female (n = 9), (6.8889 ± 1.05409), NS mean ages of male and female study participants was observed (p = 0.873). Statistically, NS difference was observed in the pain perception while administration of LA using Septoject XL or conventional needle in 6-8-year-old children. This research can be useful in the selection of the gauge of the needle to be used while planning the treatment for different behavior groups.

A comparative study on assessment methods used by high school teachers in Uganda and Turkey

Assessment and evaluation are crucial to improving educational quality. Examining the opinions of teachers from various countries on in-class assessments can significantly enhance education systems. Similarities and differences in Uganda’s and Turkey’s educational systems justify comparing them. This study aimed to examine and compare the assessment methods used by teachers working in high schools in Uganda and Turkey to determine student achievement. The researcher administered the questionnaire to 119 Ugandan and 85 Turkish high school teachers working in public and private schools in both countries. The researcher used Casual comparative research. The Mann–Whitney U test was used for data analysis. The findings show that Turkish teachers use many in-class assessment methods more often than Ugandan teachers. Compared to Turkish teachers, Ugandan teachers view themselves as more capable of giving student feedback but less competent in taking measures to increase objective scoring. The article outlines further findings and provides recommendations.

Association between sleep state misperception and bedtime behavior in patients with chronic insomnia

Previous studies on sleep state misperception have objectively evaluated sleep status in special environments using polysomnography. There is a paucity of data from studies that evaluated habitual sleep status in home environments. The present study aimed to investigate sleep state misperception in the home environment of patients with chronic insomnia using a lumbar-worn actigraphy to identify sleep habits associated with sleep state misperception severity. Thirty-one patients and 42 healthy volunteers were included in the insomnia and non-insomnia group, respectively. Participants recorded subjective assessments in sleep diaries, objective assessments with an actigraphy worn for 14 days, and self-assessments using questionnaires. Both groups had similar objective sleep ratings; however, insomnia group had significantly worse subjective ratings (total sleep time, wake after sleep onset, and sleep onset latency). A significant correlation was found between subjective and objective total sleep time scores in non-insomnia group but not in insomnia group. Insomnia group had earlier bedtimes, significantly longer bedtimes, and impaired daytime functioning (Sheehan Disability Scale score); additionally, they underestimated their total sleep time, particularly with earlier bedtimes and longer laying durations. Monitoring the sleep status and habits of individuals in home environments could be instrumental in identifying key points for targeted interventions on sleep hygiene and cognitive behavioral therapy for insomnia.

Generation of virtual monoenergetic images at 40 keV of the upper abdomen and image quality evaluation based on generative adversarial networks

BackgroundAbdominal CT scans are vital for diagnosing abdominal diseases but have limitations in tissue analysis and soft tissue detection. Dual-energy CT (DECT) can improve these issues by offering low keV virtual monoenergetic images (VMI), enhancing lesion detection and tissue characterization. However, its cost limits widespread use.PurposeTo develop a model that converts conventional images (CI) into generative virtual monoenergetic images at 40 keV (Gen-VMI40keV) of the upper abdomen CT scan.MethodsTotally 444 patients who underwent upper abdominal spectral contrast-enhanced CT were enrolled and assigned to the training and validation datasets (7:3). Then, 40-keV portal-vein virtual monoenergetic (VMI40keV) and CI, generated from spectral CT scans, served as target and source images. These images were employed to build and train a CI-VMI40keV model. Indexes such as Mean Absolute Error (MAE), Peak Signal-to-Noise Ratio (PSNR), and Structural Similarity (SSIM) were utilized to determine the best generator mode. An additional 198 cases were divided into three test groups, including Group 1 (58 cases with visible abnormalities), Group 2 (40 cases with hepatocellular carcinoma [HCC]) and Group 3 (100 cases from a publicly available HCC dataset). Both subjective and objective evaluations were performed. Comparisons, correlation analyses and Bland-Altman plot analyses were performed.ResultsThe 192nd iteration produced the best generator mode (lower MAE and highest PSNR and SSIM). In the Test groups (1 and 2), both VMI40keV and Gen-VMI40keV significantly improved CT values, as well as SNR and CNR, for all organs compared to CI. Significant positive correlations for objective indexes were found between Gen-VMI40keV and VMI40keV in various organs and lesions. Bland-Altman analysis showed that the differences between both imaging types mostly fell within the 95% confidence interval. Pearson’s and Spearman’s correlation coefficients for objective scores between Gen-VMI40keV and VMI40keV in Groups 1 and 2 ranged from 0.645 to 0.980. In Group 3, Gen-VMI40keV yielded significantly higher CT values for HCC (220.5HU vs. 109.1HU) and liver (220.0HU vs. 112.8HU) compared to CI (p < 0.01). The CNR for HCC/liver was also significantly higher in Gen-VMI40keV (2.0 vs. 1.2) than in CI (p < 0.01). Additionally, Gen-VMI40keV was subjectively evaluated to have a higher image quality compared to CI.ConclusionCI-VMI40keV model can generate Gen-VMI40keV from conventional CT scan, closely resembling VMI40keV.

An End-to-End Geometric Characterization-aware Semantic Instance Segmentation Network for ALS Point Clouds

Abstract. Semantic instance segmentation from scenes, serving as a crucial role for 3D modelling and scene understanding. Conducting semantic segmentation before grouping instances is adopted by the existing state-of-the-art methods. However, without additional refinement, semantic errors will fully propagate into the grouping stage, resulting in low overlap with the ground truth instance. Furthermore, the proposed methods focused on indoor level scenes, which are limited when directly applied to large-scale outdoor Airborne Laser Scanning (ALS) point clouds. Numerous instances, significant object density and scale variations make ALS point clouds distinct from indoor data. In order to address the problems, we proposed a geometric characterization-aware semantic instance segmentation network, which utilized both semantic and objectness score to select potential points for grouping. And in point cloud feature learning stage, hand-craft geometry features are taken as input for geometric characterization awareness. Moreover, to address errors propagated from previous modules after grouping, we have additionally designed a per-instance refinement module. To assess semantic instance segmentation, we conducted experiments on an open-source dataset. Additionally, we performed semantic segmentation experiments to evaluate the performance of our proposed point cloud feature learning method.

How Do Discrepancies between Subjective and Objective Health Predict the Risk of Injurious Falls? A Study of Community-Dwelling Swedish Older Adults

ObjectivesPrevious studies demonstrated that discrepancies between subjective and objective health measures are associated with physical and mental health–related outcomes in older adults. We investigate whether such discrepancies are also associated with risk of injurious falls in community-dwelling Swedish older adults. DesignA prospective, observational cohort study. Setting and ParticipantsUsing data from the Swedish National Study on Aging and Care in Kungsholmen, we followed 2222 community-dwelling older adults aged ≥60 years at baseline, across a 10-year period of data collection (2001-2011). MethodsA “health asymmetry” metric classified older adults into 4 categories, based on the level of agreement between their subjective and objective health scores (“health pessimist”, “health optimist”, “poor health realist”, and “good health realist”). Time-varying Cox proportional hazard and Laplace regressions were employed to investigate if these categories were associated with the risk of injurious falls. ResultsOver a 10-year follow-up, 23.5% of the sample experienced an injurious fall. Health optimists had the greatest risk of experiencing an injurious fall [hazard ratio (HR) 2.16, 95% confidence interval (CI) 1.66, 2.80], compared with good health realists. Poor health realists (HR 1.77, 95% CI 1.50, 2.11) and health pessimists (HR 1.66, 95% CI 1.21, 2.29) also had an increased risk of experiencing injurious falls, compared with good health realists. Being a health pessimist was only associated with the risk of injurious falls within the younger-old (HR 2.43, 95% CI 1.63, 3.64) and among males (HR 1.95, 95% CI 1.14, 3.33). Conclusions and ImplicationsOlder adults with similar objective health levels may differ in terms of their injurious fall risk, depending on their subjective health. Interpreting subjective health alongside objective health is clinically pertinent when assessing injurious fall risk.

Ultrasound-guided mid-point transverse process to pleura block versus thoracic paravertebral block in pediatric open-heart surgery: A randomized controlled non-inferiority study

Study objectiveThe mid-point transverse process to pleura block (MTPB) is a new variant of thoracic paravertebral block (TPVB). This study aimed to compare TPVB and MTPB with respect to intraoperative attenuation of the hemodynamic stress response to surgery and postoperative analgesia in pediatric open heart surgery with midline sternotomy. DesignA single-center, randomized, controlled, double-blind, non-inferiority study. SettingTertiary care children's university hospital. PatientsWe recruited 83 children aged 2–12 years of both sexes with American Society of Anesthesiologists (ASA) physical status class II who were scheduled for elective open cardiac surgeries with midline sternotomy for the repair of simple noncyanotic congenital heart defects. InterventionsEligible participants were randomized into either the TPVB or MTPB groups at a ratio of 1:1. In the TPVB group, patients were bilaterally injected with 0.4 ml/kg of 0.25% bupivacaine in the paravertebral space at T4 and T5. In the MTPB group, patients were bilaterally injected with 0.4 ml/kg of 0.25% bupivacaine mid-transverse process and pleura just posterior to superior costotransverse ligament at the level of T4 and T5. MeasurementsThe primary outcome was the hemodynamic responses to sternotomy incision, including heart rate (HR) and invasive mean arterial pressure (MAP), recorded before and after the induction of anesthesia, after skin incision, after sternotomy, 15 min after cardiopulmonary bypass (CPB), and after the closure of the sternum. The secondary outcomes were time needed to perform the bilateral block, intraoperative fentanyl consumption, postoperative fentanyl consumption, modified objective pain score (MOPS) measured at 1, 2, 6, 12, 18, and 24 h after extubation, extubation time, intensive care unit (ICU) discharge time, and the incidence of non-surgical complications (postoperative pruritus, postoperative vomiting, pneumothorax, hematoma or local anesthetic toxicity). Main resultsThere were no significant differences in HR and MAP in the TPVB group compared with the MTPB group at the following time points: baseline, after induction, after skin incision, after sternotomy, 15 min after CPB, and after sternal closure. Intergroup comparisons of HR and MAP did not reveal significant differences between the groups. The median (IQR) time needed to perform bilateral MTPB (7[6–8] min) was significantly (p < 0.001) shorter than that of TPVB (12[10−13] min). Intraoperative fentanyl consumption and fentanyl consumption in the first postoperative 24 h after extubation were similar in the TPVB and MTPB groups (4[2–4] vs 4[2–4] and 4.66 ± 0.649 vs 4.88 ± 1.082 μg/kg), respectively. Extubation time and ICU discharge time were comparable in the TPVB and MTPB groups (2[1–3] vs 2[1–3] h and 21.2 ± 2.5 vs 20.8 ± 2.6 h), respectively. Measurements of MOPS pain scores at 1, 2, 6, 12, 18, and 24 h after extubation were similar in both groups. The incidence of nonsurgical complications was similar in both groups. ConclusionsMTPB is non-inferior to TPVB in attenuating the intraoperative hemodynamic stress response to noxious surgical stimuli and in reducing perioperative opioid consumption, extubation time, and ICU discharge time. Moreover, MTPB is technically easier than TPVB and requires less time to perform.Clinical trial registration numberThe clinical trial registration was prospectively performed at the Pan African Clinical Trials Registry (PACTR202204901612169, approval date 01/04/2022, URL https://pactr.samrc.ac.za/TrialDisplay.aspx?TrialID=22602).

Analysis of factors affecting in-hospital emergency response capability based on objective assessment

To analyze the factors affecting the quality of cardiopulmonary resuscitation (CPR) performed by medical staff in hospital and to explore the training methods to enhance their in-hospital emergency response capabilities. A cross-sectional study was conducted, involving medical staff of intensive care unit (ICU) and general internal medicine wards in China-Japan Friendship Hospital in December 2021. The American Heart Association (AHA) resuscitation quality improvement (RQI) model was used to evaluate the skills of the subjects in performing external chest compressions and bag-mask ventilation on adult and infant simulators. While ICU subjects were undergoing RQI model objective assessment, two instructors also provided subjective scoring for their operations. The study compared the differences in RQI model objective assessment scores between ICU and general internal medicine ward subjects, between doctors and nurses, in the RQI model objective scoring for adult and infant resuscitation, in the scoring differences of different positions for chest compressions, and the differences between traditional subjective scoring and RQI objective scoring when ICU subjects were assessed for compression and ventilation. A total of 75 medical staffs were enrolled, consisting of 50 from the ICU (including 24 doctors and 26 nurses) and 25 from the general internal medicine wards (including 10 doctors and 15 nurses). The ICU medical staff's scores for adult resuscitation skills were significantly higher than those of the general internal medicine ward medical staff [adult compression score: 82.5 (66.0, 96.5) vs. 65.0 (52.5, 74.5), adult ventilation score: 82.0 (68.8, 98.0) vs. 61.0 (48.0, 82.0), both P < 0.01]. The nursing group's compression scores for both adult and infant were significantly higher than those of the doctor group [adult compression score: 77.0 (68.5, 89.5) vs. 63.0 (40.8, 90.3), infant compression score: 54.4±25.1 vs. 41.5±18.5, both P < 0.05]. The compression and ventilation scores for the infant were significantly lower than those for adult resuscitation [compression score: 48 (29, 65) vs. 76 (58, 90), ventilation score: 56 (42, 75) vs. 76 (60, 96), both P < 0.01]. When the rescuer was positioned on the right side of the model, the compression score for the adult significantly increased [79.0 (65.0, 92.0) vs. 65.0 (51.3, 77.0), P < 0.05]. The ICU medical staff's traditional subjective scores of compression and ventilation assessments for adult were significantly higher than the RQI model objective scores [adult compression score: 88.8 (79.4, 92.5) vs. 82.5 (66.0, 95.5), adult ventilation score: 95.0 (80.0, 98.1) vs. 82.0 (68.8, 98.0), both P < 0.01]. Rich experience in emergency rescue is related to the improvement of CPR skills, and performing chest compressions from the right side of the adult model is more effective. Objective scoring of resuscitation skills based on the RQI model may more accurately reflect the performance of the trainees.

Characterization of cancer survivors clustered by subjective and objective cognitive function scores.

Cancer-related cognitive impairment (CRCI) is a prevalent condition that significantly impacts the quality of life of individuals who receive cancer treatment. Clinical management of CRCI presents challenges due to the absenceof a standardized assessment. This study identified clinically relevant phenotypic clusters of CRCI based on subjective and objective cognitive function scores. In this cross-sectional study, participants were clustered using the VARCLUS™ based on subjective cognitive impairment assessed through the PROMIS® version 1.0 short-form subscales of cognitive abilities and cognitive concerns and the CANTAB Cambridge Cognition® scores, which included measures of visuospatial working memory capacity, visual episodic memory, new learning, working memory, executive function, and sustained attention. Each cluster's characteristics were described using demographics, physical and psychosocial factors (physical function, affect, optimism, and social support), and psychoneurological symptoms (anxiety, depression, fatigue, neuropathic pain, and sleep disturbance). We obtained five clusters from a total of 414 participants, where 99% were female, and 93% were self-reported white. Clusters 4 and 5 showed the highest PROMIS® cognitive abilities and the lowest measures of cognitive concern, while Clusters 1 and 2 showed the lowest cognitive abilities and the highest cognitive concerns. Clusters 4 and 5 had higher education, income, employment, and higher scores in physical function, positive affect, optimism, and social support. Additionally, individuals in these clusters were less prone to experience severe cancer-related psychoneurological symptoms. Our clustering approach, combining subjective and objective cognitive function information, shows promise in identifying phenotypes that hold clinical relevance for categorizing patient presentation of CRCI and facilitating individualized management strategies.

Patient’s perception of cancer treatment outcomes in geriatric age groups: A retrospective analysis from a tertiary care centre in India.

e13774 Background: Geriatric population forms a significant part of the total cancer patients in any given country and their expectations, their needs and challenges are different from younger patients. Patients may perceive their “chances” differently from what is expected with cancer treatment. In our analysis we aimed to look at such perceived intent of therapy in geriatric patients and factors that might influence these perceptions. Methods: We retrospectively looked at data of comprehensive geriatric assessment (CGA) which is maintained by the geriatric clinic at our institute. Patients are referred to our geriatric clinic after their joint clinic meetings and after their meetings with their primary oncologists. We identified 2962 patients who underwent CGA and collected data of age, gender, social support, marital status, education level, actual intent of therapy, patients’ perception of intent, their desire of disclosure of disease status. We also collected objective scores of GDS, GAD 7, TUG and ECOG performance status. Descriptive statistics were performed to find out the factors significantly affecting patient’s perception of intent of therapy. Results: The median age of our cohort was 68 years (Interquartile range- 64-72 years). Results are shown (Table). 70.6% wanted full disclosure of disease. Out of 1404 patients who were in palliative setting, 40.2 percent patient had misperception of treatment. Conclusions: Our data highlights the significant impact of patient’s general wellbeing both physical and mental on the perception of their treatment goals. It brings forth the need to address these issues along with cancer therapy in an already vulnerable geriatric population. Our data also highlights the desire to know about the disease status in majority which may empower terminal patients to spend their time and energy on things they value. A nearly 41% misperception in palliative patients is indicative of an urgent need for better communication practices to help patients be more aware of outcomes and thus may be able to put more quality in the limited time they have.
