3D fusion is superior to 2D point-to-point contrast-enhanced US to evaluate the ablative margin after RFA for hepatocellular carcinoma.

To compare the efficiency of three-dimensional (3D) and two-dimensional (2D) contrast-enhanced ultrasound (CEUS)-derived techniques in evaluating the ablative margin (AM) after radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). In total, 98 patients with 98 HCCs were enrolled. The 2D CEUS point-to-point imaging (2D CEUS-PI) was conducted by comparing the pre- and post-RFA 2D CEUS images manually, and the 3D CEUS fusion imaging (3D CEUS-FI) was conducted by fusing the pre- and post-RFA 3D CEUS images automatically. These two techniques were compared in distinguishing an adequate AM ≥ 5mm. Risk factors for local tumor progression (LTP) after RFA were analyzed by the Kaplan-Meier method with log-rank test. The mean registration time of 3D CEUS-FI and 2D CEUS-PI was 5.0 and 9.3min, respectively (p < 0.0001). The kappa coefficient was 0.680 for agreement between 2D CEUS-PI and 3D CEUS-FI in the evaluation of AM (p < 0.0001). Tumors with AM < 5mm by 2D CEUS-PI were all identified as AM < 5mm by 3D CEUS-FI. Nonetheless, 16 (26%) tumors identified as AM ≥ 5mm by 2D CEUS-PI were re-classified as AM < 5mm by 3D CEUS-FI. During a median follow-up time of 31.2months (range, 3.2-66.0months), LTP was identified in 8 tumors. The estimated 1-/2-/3-year cumulative incidence of LTP was 4.4%, 8.1%, and 10.3%, respectively. Higher estimated cumulative incidence of LTP was identified in tumors with AM < 5mm by 2D CEUS-PI (at 3-year, 27.2% vs 0%; p < 0.001), and by 3D CEUS-FI (at 3-year, 20.7% vs 0%; p = 0.004). 3D CEUS-FI excelled in the evaluation of AM when compared with 2D CEUS-PI. With equivalent efficacy in the prediction of LTP, 3D CEUS-FI was superior to 2D CEUS-PI for its automatic and time-saving procedure. 3D CEUS fusion imaging may serve as an effective tool in evaluating ablative margin and predicting local tumor progression after RFA in HCC. • Both 2D and 3D CEUS-derived techniques could evaluate ablative margin (AM) after RFA for hepatocellular carcinoma. • 3D CEUS fusion imaging was more precise in the evaluation of AM compared to 2D CEUS point-to-point imaging, with advantages of its automatic and time-saving procedure. • An inadequate AM < 5mm evaluated by CEUS-derived techniques was the only risk factor of LTP after RFA for hepatocellular carcinoma (p < 0.001 for 2D CEUS point-to-point imaging, and p = 0.004 for 3D CEUS fusion imaging).

Factors affecting augmented reality head-mounted device performance in real OR.

Over the last years, interest and efforts to implement augmented reality (AR) in orthopedic surgery through head-mounted devices (HMD) have increased. However, the majority of experiments were preclinical and within a controlled laboratory environment. The operating room (OR) is a more challenging environment with various confounding factors potentially affecting the performance of an AR-HMD. The aim of this study was to assess the performance of an AR-HMD in a real-life OR setting. An established AR application using the HoloLens 2 HMD was tested in an OR and in a laboratory by two users. The accuracy of the hologram overlay, the time to complete the trial, the number of rejected registration attempts, the delay in live overlay of the hologram, and the number of completely failed runs were recorded. Further, different OR setting parameters (light condition, setting up partitions, movement of personnel, and anchor placement) were modified and compared. Time for full registration was higher with 48s (IQR 24s) in the OR versus 33s (IQR 10s) in the laboratory setting (p < 0.001). The other investigated parameters didn't differ significantly if an optimal OR setting was used. Within the OR, the strongest influence on performance of the AR-HMD was different light conditions with direct light illumination on the situs being the least favorable. AR-HMDs are affected by different OR setups. Standardization measures for better AR-HMD performance include avoiding direct light illumination on the situs, setting up partitions, and minimizing the movement of personnel.

Sistem Informasi Penerimaan Siswa Baru Berbasis Android dengan Push Notifikasi di SMK PGRI 1 Palembang

SMK PGRI 1 Palembang annually holds PSB activities where currently prospective new students can register by coming directly to the information section, filling out the Google Forms form, or contacting the WA PSB officer. These three registration methods have several drawbacks such as additional expenses for ATK and transportation, as well as a limited registration time. In addition, officers must re-enter data from new prospective students with the existing desktop system because the database has not yet been integrated and new prospective students need to be contacted one by one if there are changes such as changes to the briefing schedule. This resulted in PSB activities at SMK PGRI 1 PALEMBANG being less efficient, tiring, and slow. The proposed solution to the problem is to create an Android-based PSB application with push notifications and integrated with the current MSYQL database. Push notifications allow direct notifications to be sent to certain parties if an event occurs such as a new registration or registration being responded to by the admin. This means that new registrations can be immediately recognized and responded to by the admin.

Multi-sensor remote sensing image alignment based on fast algorithms

Abstract Remote sensing image technology to the ground has important guiding significance in disaster assessment and emergency rescue deployment. In order to realize the fast automatic registration of multi-sensor remote sensing images, the remote sensing image block registration idea is introduced, and the image reconstruction is processed by using the conjugate gradient descent (CGD) method. The scale-invariant feature transformation (SIFT) algorithm is improved and optimized by combining the function-fitting method. By this way, it can improve the registration accuracy and efficiency of multi-sensor remote sensing images. The results show that the average peak signal-to-noise ratio of the image processed by the CGD method is 25.428. The average root mean square value is 17.442. The average image processing time is 6.093 s. These indicators are better than the passive filter algorithm and the gradient descent method. The average accuracy of image registration of the improved SIFT registration method is 96.37%, and the average image registration time is 2.14 s. These indicators are significantly better than the traditional SIFT algorithm and speeded-up robust features algorithm. It is proved that the improved SIFT registration method can effectively improve the accuracy and operation efficiency of multi-sensor remote sensing image registration methods. The improved SIFT registration method effectively solves the problems of low accuracy and long time consumption of traditional multi-sensor remote sensing image fast registration methods. While maintaining high registration accuracy, it improves the image registration speed and provides technical support for a rapid disaster assessment after major disasters such as earthquakes and floods. And it has an important value for the development of the efficient post-disaster rescue deployment.

Simultaneous Ground and Satellite Measurements of the Polarization Jet at the Yakutsk Station Meridian

The data of simultaneous measurements of the polarization jet from the Yakutsk ground-based vertical radio sounding station and satellite observations of narrow electron density dips or fast westward drifts of the ionospheric plasma from satellites of the Defense Meteorological Satellite Program (DMSP) series. The events are based on ground-based ionospheric measurements and cover the time interval from March 1989 to December 2015, i.e. about 26 years. The simultaneity of observations is ensured by a time period of approximately ±1.5 h from the time of registration of signs of a polarization jet according to the data of a ground-based ionospheric sounding station or by the an orbital period of DMSP satellites around the Earth. Based on data of long-term simultaneous satellite and ground-based measurements (126 events), it was shown and confirmed that the presence of characteristic additional traces of reflections on ionograms indicates the presence of narrow and fast drifts of ionospheric plasma or a polarization jet near the zenith of the observation station. It is also shown that the quasi-instantaneous longitude extent of a polarization jet at subauroral latitudes can in some cases reach 8 h or 120° by longitude.

Learning curves for robotic-assisted spine surgery: an analysis of the time taken for screw insertion, robot setting, registration, and fluoroscopy.

The purpose of this study was to clarify the learning curve for robotic-assisted spine surgery. We analyzed the workflow in robotic-assisted spine surgery and investigated how much experience is required to become proficient in robotic-assisted spine surgery. The data were obtained from consecutive 125 patients who underwent robotic-assisted screw placement soon after introducing a spine robotic system at a single center from April 2021 to January 2023. The 125 cases were divided into phases 1-5 of sequential groups of 25 cases each and compared for screw insertion time, robot setting time, registration time, and fluoroscopy time. There were no significant differences in age, body mass index, intraoperative blood loss, number of fused segments, operation time, or operation time per segment between the 5 phases. There were significant differences in screw insertion time, robot setting time, registration time, and fluoroscopy time between the 5 phases. The screw insertion time, robot setting time, registration time, and fluoroscopy time in phase 1 were significantly longer than those in phases 2, 3, 4, and 5. In an analysis of 125 cases after the introduction of the spine robotic system, the screw insertion time, robot setting time, registration time, and fluoroscopy time were significantly longer in the 25 cases in the period initially after introduction. The times were not significantly different in the subsequent 100 cases. Surgeons can be proficient in robotic-assisted spine surgery after their experience with 25 cases.

Radiotherapy trend in elderly hepatocellular carcinoma: retrospective analysis of patients diagnosed between 2005 and 2017.

To report the trends of radiotherapy in the management of elderly patients with hepatocellular carcinoma (HCC). We retrospectively reviewed patients who entered HCC registry of Samsung Medical Center between 2005 and 2017. Patients who were 75 years or older at the time of registration were defined as elderly. They were categorized into three groups based on the year of registration. Radiotherapy characteristics were compared between the groups to observe differences by age groups and period of registration. Out of 9,132 HCC registry patients, elderly comprised 6.2% (566 patients) of the registry, and the proportion increased throughout the study period (from 3.1% to 11.4%). Radiotherapy was administered to 107 patients (18.9%) in elderly group. Radiotherapy utilization in the early treatment process (within 1 year after registration) has rapidly increased from 6.1% to 15.3%. All treatments before 2008 were delivered with two-dimensional or three-dimensional conformal radiotherapy, while more than two-thirds of treatments after 2017 were delivered with advanced techniques such as intensity-modulated radiotherapy, stereotactic body radiotherapy, or proton beam therapy. Overall survival (OS) of elderly was significantly worse than younger patients. However, for patients who received radiotherapy during the initial management (within one month after registration), there was no statistically significant difference in OS between age groups. The proportion of elderly HCC is increasing. Radiotherapy utilization and adoption of advanced radiotherapy technique showed a consistently increasing trend for the group of patients, indicating that the role of radiotherapy in the management of elderly HCC is expanding.

Juridical Study of Registration Period Transfer of Land Ownership Rights at the Land Office Jayapura City

In Jayapura City there are still many people who have not registered the transfer of rights as heirs, so land registration related to the time of land registration in Jayapura City is very important and needs attention. The purpose of this research is to find out the time of registration of the transfer of land rights and the factors that cause the heirs not to register the transfer of their land rights to the Jayapura City Land Office. The method used in this research is normative and empirical law. Research has shown that registration of transfer of title based on inheritance submitted within six months of the death of the testator is free of charge. If the real estate to be inherited is not registered, it is necessary to submit documents proving ownership or a certificate that the real estate has not been certified in the land registry. The reasons for the heirs not registering the transfer of their land rights at the Jayapura City Land Office include the lack of public understanding of the transfer of land rights through inheritance, and the amount of funds and fees that must be paid.

Natural history of NASH cirrhosis in liver transplant waitlist registrants

Non-alcoholic steatohepatitis (NASH) cirrhosis is rapidly growing as an indication for liver transplant(ation) (LT). However, the natural history of NASH cirrhosis among LT waitlist registrants has not been established. The present study aimed to define the natural history of NASH cirrhosis using the Scientific Registry of Transplant Recipients database. The study cohort comprised patients registered on the LT waitlist between 1/1/2016 to 12/31/2021. The primary outcomes included probability of LT and waitlist mortality, comparing NASH (n= 8,120) vs. non-NASH (n= 21,409) cirrhosis. Patients with NASH cirrhosis were listed with lower model for end-stage liver disease (MELD) scores despite bearing a greater burden of portal hypertension, especially at lower MELD scores. The overall transplant probability in LT waitlist registrants with NASH [vs. non-NASH] cirrhosis was significantly lower at 90 days (HR 0.873, p <0.001) and 1 year (HR 0.867, p <0.001); this was even more pronounced in patients with MELD scores >30 (HR 0.705at 90 days and HR 0.672at 1 year, p <0.001 for both). Serum creatinine was the key contributor to MELD score increases leading to LT among LT waitlist registrants with NASH cirrhosis, while bilirubin was in patients with non-NASH cirrhosis. Finally, waitlist mortality at 90 days (HR 1.15, p <0.001) and 1 year (1.25, p <0.001) was significantly higher in patients with NASH cirrhosis compared to those with non-NASH cirrhosis. These differences were more pronounced in patients with lower MELD scores at the time of LT waitlist registration. LT waitlist registrants with NASH cirrhosis are less likely to receive a transplant compared to patients with non-NASH cirrhosis. Serum creatinine was the major contributor to MELD score increases leading to LT in patients with NASH cirrhosis. This study provides important insights into the distinct natural history of non-alcoholic steatohepatitis (NASH) cirrhosis among liver transplant (LT) waitlist registrants, revealing that patients with NASH cirrhosis face lower odds of transplantation and higher waitlist mortality than those with non-NASH cirrhosis. Our study underscores the significance of serum creatinine as a crucial contributor to model for end-stage liver disease (MELD) score in patients with NASH cirrhosis. These findings have substantial implications, emphasizing the need for ongoing evaluation and refinement of the MELD score to more accurately capture mortality risk in patients with NASH cirrhosis on the LT waitlist. Moreover, the study highlights the importance of further research investigating the impact of the implementation of MELD 3.0 across the US on the natural history of NASH cirrhosis.

Time-Domain Multiply–Accumulate Unit

In this article, a novel approach for performing multiply–accumulate (MAC) operations in the time-domain is presented. The Internet of Things, machine learning, and 5G are driving up demand for this type of operation, which is also crucial for many applications that rely on digital signal processing (DSP). For accomplishing this operation, a fully time-domain MAC unit capable of consecutively multiplying two input time pulses and adding them to previously stored signals is proposed. The main component of the circuit is the time register, which adds and stores time information. The MAC unit design is realized in commercial 180-nm CMOS process and occupies an estimated area of about 3167 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\mu$</tex-math> </inline-formula> m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .

Implementation of Face Recognition for Patient Identification Using the Transfer Learning Method

The hospital's status as a health center requires it to ensure patient safety, decrease incidents and treat patients. Identification of the patient is the primary source of patient safety difficulties. In addition to the patient's name and number, further patient-identifying components are needed to reduce this neglect. This work provides a solution in the form of biometric authentication, namely, face recognition. The convolutional neural network (CNN) approach can enable machine facial recognition. CNN is one of the deep learning techniques used to detect and identify picture objects. In this study, facial recognition was carried out using the transfer learning technique, VGGFace2 model pretraining, and SENet 50 model architecture. The dataset was collected via one-shot learning or a single sample per individual sampling. Applying the CNN model to the patient identification system yields two distinct outcomes: patient registration and verification. Registration utilizes a minimum distance of 0.35 and matches data with the complete database, whereas patient verification has a minimum distance of 0.28 and matches only the face in question. At the time of patient registration, the accuracy was between 90% and 100%. However, at the time of patient verification, the accuracy was 100%.

A Speedy Point Cloud Registration Method Based on Region Feature Extraction in Intelligent Driving Scene.

The challenges of point cloud registration in intelligent vehicle driving lie in the large scale, complex distribution, high noise, and strong sparsity of lidar point cloud data. This paper proposes an efficient registration algorithm for large-scale outdoor road scenes by selecting the continuous distribution of key area laser point clouds as the registration point cloud. The algorithm extracts feature descriptions of the key point cloud and introduces local geometric features of the point cloud to complete rough and fine registration under constraints of key point clouds and point cloud features. The algorithm is verified through extensive experiments under multiple scenarios, with an average registration time of 0.5831 s and an average accuracy of 0.06996 m, showing significant improvement compared to other algorithms. The algorithm is also validated through real-vehicle experiments, demonstrating strong versatility, reliability, and efficiency. This research has the potential to improve environment perception capabilities of autonomous vehicles by solving the point cloud registration problem in large outdoor scenes.

A Pilot Human Cadaveric Study on Accuracy of the Augmented Reality Surgical Navigation System for Thoracolumbar Pedicle Screw Insertion Using a New Intraoperative Rapid Registration Method.

To evaluate the feasibility and accuracy of AR-assisted pedicle screw placement using a new intraoperative rapid registration method of combining preoperative CT scanning and intraoperative C-arm 2D fluoroscopy in cadavers. Five cadavers with intact thoracolumbar spines were employed in this study. Intraoperative registration was performed using anteroposterior and lateral views of preoperative CT scanning and intraoperative 2D fluoroscopic images. Patient-specific targeting guides were used for pedicle screw placement from Th1-L5, totaling 166 screws. Instrumentation for each side was randomized (augmented reality surgical navigation (ARSN) vs. C-arm) with an equal distribution of 83 screws in each group. CT was performed to evaluate the accuracy of both techniques by assessing the screw positions and the deviations between the inserted screws and planned trajectories. Postoperative CT showed that 98.80% (82/83) screws in ARSN group and 72.29% (60/83) screws in C-arm group were within the 2-mm safe zone (p < 0.001). The mean time for instrumentation per level in ARSN group was significantly shorter than that in C-arm group (56.17 ± 3.33s vs. 99.22 ± 9.03s, p < 0.001). The overall intraoperative registration time was 17.2 ± 3.5s per segment. AR-based navigation technology can provide surgeons with accurate guidance of pedicle screw insertion and save the operation time by using the intraoperative rapid registration method of combining preoperative CT scanning and intraoperative C-arm 2D fluoroscopy.

Utility of Ferritin at Registration as a Screen for Development of Anemia in Third Trimester [ID: 1362276

INTRODUCTION: The objective of this study was to assess the utility of screening ferritin (&lt;20 weeks of gestation) in pregnant patients on hemoglobin (Hgb) and hematocrit (Hct) later in gestation. METHODS: Pregnant patients who received nondiagnostic ferritin labs at less than 20 weeks of gestation from 2019 to 2021 were retrospectively identified. Patients were excluded if ferritin testing was conducted for diagnostic purposes or if the patient had a history of anemia. Labs at the time of registration, 28 weeks of gestation, and at delivery were analyzed. Anemia was defined as Hgb less than 11 g/dL. This study was approved by the University of Washington IRB, and patient consent was waived. RESULTS: Forty-four patients underwent routine ferritin screening at registration, with ferritin levels ranging from 10 to 136 ng/mL (average 52.5 ng/mL). Average Hgb/Hct at registration were 12.6 g/dL and 37.3%, respectively. At 28 weeks of gestation, Hgb/Hct were obtained on 42 patients, of whom 9 patients were diagnosed with anemia. Patients diagnosed with anemia had a screening ferritin level of 33.6 ng/mL, and nonanemic patients had a ferritin level of 57.4 ng/mL (P=.1). When a cutoff of 50 ng/mL was studied to compare patients with “low” versus “normal” ferritin, ferritin less than or equal to 50 ng/mL had significantly lower Hgb levels at 28 weeks compared to those with ferritin greater than 50 ng/mL (P=.013). On labor and delivery (L&amp;D), Hgb/Hct was obtained on 44 patients, and 14 were diagnosed with anemia. Anemic patients on L&amp;D had significantly lower screening ferritin compared to nonanemic, 31.9 and 62.2 ng/mL, respectively (P=.016). CONCLUSION: Ferritin screening in early pregnancy may help predict lower Hgb in later gestation. Using a higher ferritin cutoff of 50 ng/mL in early pregnancy for identifying patients at risk for anemia in the third trimester may be warranted. Larger prospective studies are needed to evaluate further the utility of ferritin screening.

Multiresolution discrete optimization registration method of ultrasound and magnetic resonance images based on key points

The registration of preoperative magnetic resonance (MR) images and intraoperative ultrasound (US) images is very important in the planning of brain tumor surgery and during surgery. Considering that the two-modality images have different intensity range and resolution, and the US images are degraded by lots of speckle noises, a self-similarity context (SSC) descriptor based on local neighborhood information was adopted to define the similarity measure. The ultrasound images were considered as the reference, the corners were extracted as the key points using three-dimensional differential operators, and the dense displacement sampling discrete optimization algorithm was adopted for registration. The whole registration process was divided into two stages including the affine registration and the elastic registration. In the affine registration stage, the image was decomposed using multi-resolution scheme, and in the elastic registration stage, the displacement vectors of key points were regularized using the minimum convolution and mean field reasoning strategies. The registration experiment was performed on the preoperative MR images and intraoperative US images of 22 patients. The overall error after affine registration was (1.57 ± 0.30) mm, and the average computation time of each pair of images was only 1.36 s; while the overall error after elastic registration was further reduced to (1.40 ± 0.28) mm, and the average registration time was 1.53 s. The experimental results show that the proposed method has prominent registration accuracy and high computational efficiency.

Estimating complete cancer prevalence in Europe: validity of alternative vs standard completeness indexes.

Comparable indicators on complete cancer prevalence are increasingly needed in Europe to support survivorship care planning. Direct measures can be biased by limited registration time and estimates are needed to recover long term survivors. The completeness index method, based on incidence and survival modelling, is the standard most validated approach. Within this framework, we consider two alternative approaches that do not require any direct modelling activity: i) empirical indices derived from long established European registries; ii) pre-calculated indices derived from US-SEER cancer registries. Relying on the EUROCARE-6 study dataset we compare standard vs alternative complete prevalence estimates using data from 62 registries in 27 countries by sex, cancer type and registration time. For tumours mostly diagnosed in the elderly the empirical estimates differ little from standard estimates (on average less than 5% after 10-15 years of registration), especially for low prognosis cancers. For early-onset cancers (bone, brain, cervix uteri, testis, Hodgkin disease, soft tissues) the empirical method may produce substantial underestimations of complete prevalence (up to 20%) even when based on 35-year observations. SEER estimates are comparable to the standard ones for most cancers, including many early-onset tumours, even when derived from short time series (10-15 years). Longer observations are however needed when cancer-specific incidence and prognosis differ remarkably between US and European populations (endometrium, thyroid or stomach). These results may facilitate the dissemination of complete prevalence estimates across Europe and help bridge the current information gaps.

Electroacupuncture at Baliao point alleviates post-operative pain and anal distension after procedure for prolapse and hemorrhoids (stapled hemorrhoidopexy): a prospective randomized clinical trial

PurposeThe purpose of this study was to explore the effect of electroacupuncture (EA) at Baliao point on short-term complications, such as anal pain and swelling, after procedure for prolapse and hemorrhoids (PPH) in patients with mixed hemorrhoids.MethodsA total of 124 eligible patients undergoing PPH surgery were included in this study and randomly divided into a control group (n = 67) and an EA group (n = 57), with patients in the control group receiving only PPH surgery and patients in the EA group receiving PPH surgery and EA at Baliao point.ResultsThe visual analogue scale (VAS) scores of EA group at 8, 24, 48, and 72 h after operation were significantly lower than those of control group. The anal distension scores at 8, 48, and 72 h after operation were also significantly lower than those of control group. The number of postoperative analgesic drug administration per patient was also significantly lower in the EA group. The incidence of urinary retention and tenesmus in EA group was significantly lower than that in control group within the first day after surgery.ConclusionEA treatment at the Baliao point can alleviate short-term anal pain and anal swelling after the procedure for prolapse and hemorrhoids, reduce the incidence of urinary retention, and decrease the use of postoperative analgesic drugs.Trial registrationThis study was approved and registered by the Chinese Clinical Trial Center, Registration number: ChiCTR2100043519, Registration time: February 21, 2021 (https://www.chictr.org.cn/).

Predicting a kidney transplant patient’s pre-transplant functional status based on information from waitlist registration

With over 100,000 patients on the kidney transplant waitlist in 2019, it is important to understand if and how the functional status of a patient may change while on the waitlist. Recorded both at registration and just prior to transplantation, the Karnofsky Performance Score measures a patient’s functional status and takes on values ranging from 0 to 100 in increments of 10. Using machine learning techniques, we built a gradient boosting regression model to predict a patient’s pre-transplant functional status based on information known at the time of waitlist registration. The model’s predictions result in an average root mean squared error of 12.99 based on 5 rolling origin cross validations and 12.94 in a separate out-of-time test. In comparison, predicting that the pre-transplant functional status remains the same as the status at registration, results in average root mean squared errors of 14.50 and 14.11 respectively. The analysis is based on 118,401 transplant records from 2007 to 2019. To the best of our knowledge, there has been no previously published research on building a model to predict kidney pre-transplant functional status. We also find that functional status at registration and total serum albumin, have the most impact in predicting the pre-transplant functional status.

Therefore, delay in presentation, diagnosis, or management can increase the risk of testicular loss. While several studies have examined the time burden of multiple components of the management course for testicular torsion, our study aims to evaluate other factors, including management by the day or on-call team, management by a pediatric or adult attending, and impact of patient age. METHODS: A retrospective case-controlled study of patients with a history of testicular torsion between 2012 and 2022 at a single institution was conducted. Variables impacting testicular torsion management time was assessed using univariate analyses. RESULTS: 134 patients were included, of whom 49 underwent an orchiectomy and 84 underwent an orchiopexy. There was no significant difference between efficiency of the on-call team versus day team regarding time from registration to ultrasound (113 vs 97 min, p=0.37), ultrasound to urology consult (66 vs 86 min, p=0.46), ED registration to OR (219 vs 196 min, p=0.39), ultrasound to OR (155 vs 126 min, p=0.30), and testicular salvage rate (35.7% vs 38.8%, p=0.80). A difference was seen, however, when patients were stratified by age (>18 vs≤18 years old). Patients greater than 18 years of age had significantly longer symptom duration (91.9 vs 20.0 min, p=0.005), longer time to receive an ultrasound from ER registration (152 vs 87 min, p<0.001), longer time to OR from ER registration (268 vs 185 min, p<0.001) and longer time to OR from ultrasound read (187 vs 123 min, p=0.03). In comparing pediatric attendings to adult attendings, there was no difference in time to surgery, intraoperative length of surgery, or testicular salvage rates. Intra-operatively, adult attending urologists had shorter length of surgery approaching significance (58 minutes vs 65 min, p=0.07) and older patients had lower rates of testicular salvage approaching significance (orchiectomy rate 48.8% vs 31.5%, p=0.057). CONCLUSIONS: While no significant delays in testicular torsion management was detected between management by on-call versus day team nor pediatric versus adult attending, age of patient was associated with greater delays in receiving definitive surgical management of testicular torsion. Greater suspicion for testicular torsion diagnosis in older patients with acute scrotum may improve the rate of testicular salvage.
