In cardiology, magnetic resonance imaging (MRI) provides a clinical standard for measuring ventricular volumes. Owing to their reliability, volumetric measurements with cardiac MRI have become an essential tool for quantitative assessment of ventricular function. However, as volumetric indices are indirectly related to myocardial motion that drives ventricular filling and ejection, cardiac MRI cannot provide comprehensive evaluation of ventricular performance. To overcome this limitation, the presented work sought to measure ventricular wall motion directly with optical flow analysis of real-time cardiac MRI. By modeling left ventricle (LV) walls in real-time images based on myocardial architecture, we developed an optical flow approach to analyzing LV radial and circumferential wall motion for improved quantitative assessment of ventricular function. For proof-of-concept, a cardiac MRI study was conducted with healthy volunteers and heart failure (HF) patients. It was found that, as real-time images provided sufficient temporal information for correlation analysis between different LV wall motion velocity components, optical flow assessment detected the difference of ventricular performance between the HF patients and the healthy volunteers more effectively than volumetric measurements. We expect that this model-based optical flow assessment with real-time cardiac MRI would offer intricate analysis of ventricular function beyond conventional volumetric measurements.
In preventing Chronic Postoperative Inguinal Pain (CPIP) after inguinal herniorrhaphy, mesh position and mesh fixation seem important factors. The SOFTGRIP trial compared the TransInguinal PrePeritoneal (TIPP) repair to Polysoft mesh, to the Open anterior repair (Lichtenstein) using the self-gripping ProGrip mesh. Since CPIP might resolve and recurrence rate increase, this study reports the SOFTGRIP trial's long-term results (with a minimal follow-up of 5years).

All patients initially randomized in the SOFTGRIP trial were contacted if not deceased. Patients were invited for an interview and physical examination. The procedures and methodology of this randomized clinical trial have been published together with the short-term results. The main outcomes for this long-term follow-up study were chronic pain, recurrences, re-operations and numbness.

A total of 193 patients (81.4% of the initially randomized patients) were included for long-term follow-up analyses, 96 after TIPP, 97 after ProGrip Lichtenstein.harms of the different inguinal hernia repair techniques.

Chronic upper airway obstruction caused by adenotonsillar hypertrophy is one of the major cause of morbidity in children. It can lead to Obstructive Sleep Apnoea Syndrome, Pulmonary Hypertension, Cor Pulmonale and right heart failure. The study aimed to evaluate and compare various parameters of cardiac function with the help of echocardiography preoperatively and postoperatively in children undergoing adenotonsillectomy.

A prospective cohort study was conducted on 23 patients at an apex care institute, under the age group of 4-12years, who were diagnosed with adenotonsillar hypertrophy. Preoperative symptom analysis and Echocardiographic examination were done. After the assessment, all patients underwent surgery in the form of adenotonsillectomy. Follow-up symptom analysis and echocardiographic examination was done after 3months postoperatively.

Significant improvement in the obstructive symptoms were noted in postoperative group as expected (p =  < 0.001) and also in parameters such as mPAP (p =  &e helpful in identifying and preventing the development of cardiopulmonary complication. These changes can be reversed by performing adenotonsillectomy.
The aim of the study was to investigate the listening comprehension (LC) skills in deaf and hard of hearing children (DHH) using cochlear implants (CI). Besides, personal and audiological variablesthat could influence the levels of competence reached were analyzed.

Thirty-four children using CI were enrolled. LC skills were assessed through the standardized Italian test "Comprensione Orale-Test e Trattamento" (CO-TT). A univariate analysis was conducted to compare LC with gender, listening mode (unilateral or bilateral), maternal level of education and family income. https://www.selleckchem.com/EGFR(HER).html A bivariate analysis was performed to search possible connections between children's performances and their individual characteristics, audiological conditions, and language levels. Finally, a multivariate analysis was performed using a stepwise hierarchical linear regression model which included all variables whose p value resulted  ≤ 0.05.

Twenty-one children using CI (61.8%) showed adequate performances in terms of chronological age, while 13 (38.2%) showed difficulties in LC. Maternal level of education, age at diagnosis and non-verbal cognitive level accounted for 43% of the observed variance. Auditory attention skills explained an additional 15% of variance. Morphosyntactic comprehension added a further 12% of variance.

CI can really help many DHH children to reach adequate LC skills, but in some cases difficulties remain. Factors influencing LC need to be early investigated and considered when planning an appropriate rehabilitative intervention.

Ingestion of a toothbrush is an unusual event but may occur either accident or by intent. Radiological examinations play a crucial role in determining the exact location of the object within the gastrointestinal tract and in planning for its removal by endoscopic or surgical intervention.

Medical and radiological records of 8 patients who had swallowed the broken heads or entire toothbrush were retrospectively reviewed. This series included 4 men and 4 women, ranging in age from 21 to 57 years (mean 34 years).

Radiographs and computed tomography of the abdomen demonstrated the ingested toothbrushes within the stomach in 3, lodged in the duodenum in 1, and entrapped in various parts of the colon in 4 patients. link= https://www.selleckchem.com/EGFR(HER).html They were removed by laparotomy in 3, laparoscopy in 2, colonoscopy in 2, and upper gastrointestinal endoscopy in 1 patient. There were no perforations or associated complications, and all patients had uneventful recoveries.

Ingested toothbrushes can be easily identified on radiological studies because of the radiopaque wires holding the nylon bristles. The plastic parts of it, however, are only visible on computed tomography. All cases would require endoscopic or surgical removal of the retained toothbrushes because spontaneous passage per rectum does not occur.

Erectile Dysfunction (ED) is defined as the inability to obtain or maintain an erection firm enough for satisfactory sexual performance and affects the quality of life of over 50% of men aged over 40years. Venogenic ED is elucidated as a cause in a subgroup of patients. The study aims to investigate the clinical success, technical success, safety and durability of venous embolisation for management of venogenic ED.

After providing informed consent, and subsequent to confirmation of venogenic ED by Doppler ultrasound (dUS) and cavernosography, 80 men referred for cavernosography and pelvic vein embolisation, will undergo randomisation by a computer system either to treatment or sham groups. Efficacy will be assessed using dUS and a validated questionnaire, the International Index of Erectile Function (IIEF). Pharmacologic agents used during the trial will be recorded. The primary outcome of PiVET-ED is to establish clinical success at 3 and 6months post venous embolisation, as defined by end diastolic velocity in the cavernosal artery < 5cm/s with dUS and by a > 4-point improvement in IIEF. Durability of the embolisation procedurewill be assessed annually to 5years. Quality of life will be assessedat all study time points using the 36-Item Short Form Survey (SF-36).

The PiVET-ED trial is a prospective, randomised, single-blinded, single centre, sham controlled study, which aims to establish the safety, efficacy and durability of pelvic vein embolisation for the treatment of venogenic erectile dysfunction.

To develop and assess the accuracy of a mixed reality (MR) needle guidance application on smartglasses.

An MR needle guidance application on HoloLens2, without pre-procedural CT image reconstruction or import by manually matching the spatial and MR coordinate systems, was developed. First, the accuracy of the target locations in the image overlay at 63 points arranged on a 45 × 35 × 21cm box and needle angles from 0° to 80°, placed using the MR application, was verified. The needle placement errors from 12 different entry points in a phantom by seven operators (four physicians and three non-physicians) were compared using a linear mixed model between the MR guidance and conventional methods using protractors.

The average errors of the target locations and needle angles placed using the MR application were 5.9 ± 2.6mm and 2.3 ± 1.7°, respectively. The average needle insertion error using the MR guidance was slightly smaller compared to that using the conventional method (8.4 ± 4.0mm vs. 9.6 ± 5.1mm, p = 0.091), particularly in the out-of-plane approach (9.6 ± 3.5mm vs. 12.3 ± 4.6mm, p = 0.003). The procedural time was longer with MR guidance than with the conventional method (412 ± 134s vs. 219 ± 66s, p < 0.001).

MR needle guidance without pre-procedural CT image import is feasible when matching coordinate systems, and the accuracy of needle insertion is slightly better than that of the conventional method.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causes lung tissue damage directly by targeting cells or indirectly by producing inflammatory cytokines. However, whether functional alterations are related to metabolic changes in lung cells after SARS-CoV-2 infection remains unknown. Here, we analyzed the lung single-nucleus RNA-sequencing (snRNA-seq) data of several deceased COVID-19 patients and focused on changes in transcripts associated with cellular metabolism. We observed upregulated glycolysis and oxidative phosphorylation in alveolar type 2 progenitor cells, which may block alveolar epithelial differentiation and surfactant secretion. Elevated inositol phosphate metabolism in airway progenitor cells may promote neutrophil infiltration and damage the lung barrier. Further, multiple metabolic alterations in the airway goblet cells are associated with impaired muco-ciliary clearance. Increased glycolysis, oxidative phosphorylation, and inositol phosphate metabolism not only enhance macrophage activation but also contribute to SARS-CoV-2 induced lung injury. The cytotoxicity of natural killer cells and CD8+ T cells may be enhanced by glycerolipid and inositol phosphate metabolism. Glycolytic activation in fibroblasts is related to myofibroblast differentiation and fibrogenesis. Glycolysis, oxidative phosphorylation, and glutathione metabolism may also boost the aging, apoptosis and proliferation of vascular smooth muscle cells, resulting in pulmonary arterial hypertension. In conclusion, this preliminary study revealed a possible cellular metabolic basis for the altered innate immunity, adaptive immunity, and niche cell function in the lung after SARS-CoV-2 infection. Therefore, patients with COVID-19 may benefit from therapeutic strategies targeting cellular metabolism in future.
Premature neonates have a high risk of intraventricular hemorrhage (IVH) at birth, the blood products of which activate inflammatory cascades that can cause hydrocephalus and long-term neurological morbidities and sequelae. However, there is no consensus for one treatment strategy. While the mainstay of treatment involves CSF diversion to reduce intracranial pressure, a number of interventions focus on blood product removal at various stages including extraventricular drains (EVD), intra-ventricular thrombolytics, drainage-irrigation-fibrinolytic therapy (DRIFT), and neuroendoscopic lavage (NEL).

We performed a systematic review and meta-analysis to compare the risks and benefits commonly associated with active blood product removal treatment strategies. We searched MEDLINE, Embase, Scopus, Cochrane Library, and CINAHL databases through Dec 2020 for articles reporting on outcomes of EVDs, thrombolytics, DRIFT, and NEL. Outcomes of interest were rate of conversion to ventriculoperitoneal shunt (VPS), infec DRIFT (p  less then  0.001) but did not differ among the other modalities. NEL also had lower mortality relative to EVD (p  less then  0.001) and thrombolytics (p = 0.013), which was no longer significant after adjusting for year of publication. Thus, NEL appears to be safer than DRIFT in terms of risk of hemorrhage, and not different than other blood-product removal strategies in terms of mortality. Outcomes-in terms of shunting and cognitive impairment-did not differ. Later year of publication was predictive of lower rates of mortality, but not the other outcome variables. Further prospective and randomized studies will be necessary to directly compare NEL with other temporizing procedures.
This study describes a modified technique addressing bony defects and incomplete ossification after endoscopic strip craniectomy (ESC) for SC followed by postoperative helmet therapy (PHT). The study aims to delineate quantitative and qualitative outcomes of this modified ESC technique followed by PHT and discern the optimal duration of PHT following ESC. A secondary aim is to address the effects of the technique on bony defects.

Patients undergoing ESC followed by PHT between 2017 and 2021 were included. Patient sex, age at surgery, duration of surgery, red blood cell transfusion, length of hospital stay, PHT duration, cephalic index (CI) at multiple time points, and bony defect information were collected. Descriptive and correlative analysis was done.

Thirty-one patients (25 male, 6 female) were operated in study period. Mean age at surgery was 12.81weeks, mean duration of surgery was 57.50min, average transfused RBC volume was 32cc, mean length of hospital stay was 1.84days, mean PHT duration was 33.16weeks, and mean follow-up time was 63.42weeks. Mean preoperative CI was 70.6, and mean CI at the end of PHT was significantly higher, being 77.1. Maximum improvement in CI (CI
) took place at week 22.97. PHT duration did not have a correlation with CI at last follow up. There were no bony defects.

Modified ESC technique is effective in successful correction of sagittal craniosynostosis. CI
already takes place, while PHT is continuing, but there is no certain time point for dishelmeting. The technique avoided bony defects and incomplete ossification.

Genetic testing confirmed a rare pathogenic, sporadic, heterozygous c.2041 + 1G > A gene mutation in intron 16 of the TSC1 gene, diagnostic for tuberous sclerosis. Post-operatively, the infant remained seizure free for at least 1 year. Following recurrence of her seizures, she has continued on multiple anti-seizure medications and everolimus therapy. We review the pathological and molecular features of this condition and highlight the ethics of intervention and steps taken toward safe neurosurgical intervention in this very young infant.
To increase safety in elite alpine ski racing Injury Surveillance Systems were implemented and preventive measures introduced. link2 However, studies analysing the change in athletes' injury risk by controlling for their exposure are still scarce.

This study aimed to describe and analyse the risk of in-competition severe injury events (SIE
) in elite alpine ski racing.

Data recorded in the Austrian Ski Federation's Injury Surveillance System were used to analyse the SIE
incidence. Information on athletes' competition exposure was obtained from the official website of the International Ski Federation. In 23 seasons, 2333 skier seasons were recorded for the Austrian Ski Team. Within a total of 114,531 runs 169 SIE
occurred. Generalised Estimating Equation for Poisson Regressions were applied.

The SIE
incidence per 1000 runs was 1.48 [95% confidence interval (CI) 1.26-1.73] for elite alpine ski racers and 2.21 (95% CI 1.79-2.75) for the subgroup of World Cup racers. A significant sex difference was detected for the subgroup of junior racers with a higher risk for female athletes [risk ratio (RR) 2.97, 95% CI 1.46-6.05]. Between the seasons of 1997 and 2020, the seasonal SIE
incidence increased by a factor of 2.67 for elite alpine ski racers and 3.53 for World Cup racers. Downhill (2.75, 95% CI 2.18-3.47) had the highest SIE
incidence, followed by super-G (1.94, 95% CI 1.30-2.88), giant slalom (1.40, 95% CI 1.06-1.85), and slalom (0.64, 95% CI 0.43-0.96).

Although many preventive measures have been implemented in elite alpine ski racing, the risk of SIE
has increased over the last two decades.

MR urography has evolved into a comprehensive evaluation of the urinary tract that combines anatomical imaging with functional evaluation in a single test without ionizing radiation. Quantitative functional MR imaging is based on dynamic contrast-enhanced MR acquisitions that provide progressive, visible enhancement of the renal parenchyma and urinary tract. The signal changes related to perfusion, concentration and excretion of the contrast agent can be evaluated using both quantitative and qualitative measures. Functional evaluation with MR has continued to improve as a result of significant technical advances allowing for faster image acquisition as well as the development of new tracer kinetic models of renal function. The most common indications for MR urography in children are the evaluation of congenital anomalies of the kidney and urinary tract including hydronephrosis and renal malformations, and the identification of ectopic ureters in children with incontinence. In this paper, we review the underlying acquisition schemes and techniques used to generate quantitative functional parameters including the differential renal function (DRF), asymmetry index, mean transit time (MTT), signal intensity versus time curves as well as the calculation of individual kidney glomerular filtration rate (GFR). link2 Visual inspection and semi-quantitative assessment using the renal transit time (RTT) and calyceal transit times (CTT) are fundamental to accurate diagnosis and are used as a basis for the interpretation of the quantitative data. The importance of visual assessment of the images cannot be overstated when analyzing the quantitative measures of renal function.Herein we report synthesis of hematite (α-Fe2O3) nanorods by calcinating hydrothermally synthesized goethite nanorods at 5000C. The structural, optical and MRI imaging guided cancer therapeutic properties of fabricated nanorods have been discussed in this manscript. FESEM and TEM imaging techniques were used to confirm the nanorod like morphology of as prepared materials. As we know that Fe2O3 nanorods with size in the range of 25-30 nm exhibit super magnetism. After coating with the PEG, the as prepared nanorods can be used as T2 MR imaging contrast agents. An excellent T2 MRI contrast of 38.763 mM-1s-1 achieved which is highest reported so far for α-Fe2O3. Besides the as prepared nanorods display an excellent photothermal conversion efficiency of 39.5% thus acts as an excellent photothermal therapeutic agent. Thus, we envision the idea of testing our nanorods for photothermal therapy and MR imaging application both in vitro and in vivo, achieving an excellent T2 MRI contrast and photothermal therapy effect with as prepared PEGylated nanorods.Species with large local abundances tend to occupy more sites. One of the mechanisms proposed to explain this widely reported inter-specific relationship is a cross-scale hypothesis based on dynamics at the population level. Called the vital rates mechanism; it uses within-population demographic processes of population growth and density dependence to predict when inter-specific abundance-occupancy relationships can arise and when these relationships can weaken and even turn negative. Even though the vital rates mechanism is mathematically simple, its predictions has never been tested directly because of the difficulty estimating the demographic parameters involved. Here, using a recently introduced mark-recapture analysis method, we show that there is no relationship between abundance and occupancy among 17 bird species. Our results are consistent with the predictions of the vital rate mechanism regarding the demographic processes that are expected to weaken this relationship. Specifically, we find that intrinsic growth rate and local abundance are not correlated, and density dependence strength shows considerable variation across species. Variability in density dependence strength is related to variability in species-level local average abundance and intrinsic growth rate; species with lower growth rate have higher abundance and are strongly regulated by density dependent processes, especially acting on survival rates. More generally, our findings support a cross-scale mechanism of macroecological abundance-occupancy relationship emerging from density-dependent dynamics at the population level.Access to water through shallow groundwater wells is a common practice in coastal settlements. This, coupled with a lack of planning for wastewater disposal promotes fecal contamination of groundwater and poses a threat to human health. Here, the spatial and temporal dynamics of groundwater fecal contamination was evaluated during summer and winter (2013 and 2014) in a coastal protected area having a high touristic relevance (Cabo Polonio, Uruguay). Fecal coliforms (FC) abundance in groundwater was significantly higher during summer, related to an influx of ~ 1000 tourists per day. A significant spatial autocorrelation was found in 2014, when the abundance of FC in a well was influenced by its three nearest wells (Moran and Geary tests). The applied statistical models (mixed models) indicated that total phosphorus and organic matter were the variables significantly explaining FC abundance. The risk for human health was estimated using groundwater-extracted DNA and qPCR of genes encoding for E. coli virulence factors (stx1, stx2, and eae). Potential Shiga toxin-producing enteropathogenic and enterohemorrhagic pathotypes were detected, even at FC abundances ≤ 1 CFU (100 mL-1). Moreover, we found that contaminated groundwater reached the beach, being the presence of FC in sand detected even in winter and showing its highest frequency nearby groundwater wells consistently having high FC abundance (hot spots). Altogether, the results show that fecal contamination of shallow groundwater in Cabo Polonio involves a risk for human health that intensifies during summer (associated to a significant increase of tourists). This contamination also impacts the beach, where FC can remain through the whole year.
This study compared the mechanical behavior of two fixation techniques used in three sections representing the sagittal split ramus osteotomy (SSRO) in polyurethane replicas that were divided into groups, according to type of section, and sub-groups according to type of fixation, simulating 11-mm advancement and 6º clockwise mandibular rotation.

Loads were applied in two regions, aiming at progressive application and consequent strength value, measured in kilogram-force in displacements of 1, 3, 5, and 7mm, from the load application tip. Shapiro-Wilk test was performed, followed by two-way analysis of variance (ANOVA-2 way), and Bonferroni's multiple comparison.

The results showed no statistically significant difference in the type of section and type of fixation used when load was applied to the inter-incisor region. However, when load was applied to the first molar region, statistically significant difference was observed in 1-mm displacement, in which section described by Epker with two modifications showed greater strength, regardless of type of fixation used (p = 0.007).

In the application of load in the inter-incisor region, there was no statistical difference between the type of osteotomy and the type of fixation used. When applying loads to molars, there was a difference for the type of osteotomy, where the Epker osteotomy with 2 modifications presented greater resistance, regardless of the type of fixation used.

Monoacylglycerol lipase (MAGL) regulates cannabinoid neurotransmission and the pro-inflammatory arachidonic acid pathway by degrading endocannabinoids. MAGL inhibitors may accordingly act as cannabinoid-potentiating and anti-inflammatory agents. Although MAGL dysfunction has been implicated in neuropsychiatric disorders, it has never been visualized in vivo in human brain. The primary objective of the current study was to visualize MAGL in the human brain using the novel PET ligand
F-T-401.

Seven healthy males underwent 120-min dynamic
F-T-401-PET scans with arterial blood sampling. Six subjects also underwent a second PET scan with
F-T-401 within 2weeks of the first scan. For quantification of MAGL in the human brain, kinetic analyses using one- and two-tissue compartment models (1TCM and 2TCM, respectively), along with multilinear analysis (MA1) and Logan graphical analysis, were performed. Time-stability and test-retest reproducibility of
F-T-401-PET were also evaluated.

F-T-401 showed rapid first demonstration of in vivo visualization of MAGL in the human brain. 18F-T-401 showed excellent test-retest reliability, reversible kinetics, and stable estimation of VT values consistent with known regional MAGL expressions. PET with 18F-T-401-PET is promising tool for measurement of central MAGL.

F]FDG PET/CT is of utmost importance for radiation treatment (RT) planning and response monitoring in lung cancer patients, in both non-small and small cell lung cancer (NSCLC and SCLC). This topic has been addressed in guidelines composed by experts within the field of radiation oncology. However, up to present, there is no procedural guideline on this subject, with involvement of the nuclear medicine societies.

A literature review was performed, followed by a discussion between a multidisciplinary team of experts in the different fields involved in the RT planning of lung cancer, in order to guide clinical management. The project was led by experts of the two nuclear medicine societies (EANM and SNMMI) and radiation oncology (ESTRO).

More specifically, we prove that, under certain technical assumptions on the jump sizes and rates, there is convergence of the laws of the stochastic process to a unique stationary distribution supported far away from extinction. We show how the techniques and conditions used in proving SSP for general Kolmogorov systems driven solely by Brownian motion must be adapted and tailored in order to account for the jumps of the driving noise. We provide examples of applications to the case where the underlying food-web is (a) a 1-predator, 2-prey food-web, and (b) a multi-layer food-chain.
Accurate sex estimation is an important component of a biological profile in forensic anthropology. The pelvis is widely accepted as the most dimorphic osseous structure, and thus, this dimorphism is also reflected by the sacrum.

This study aimed to explore sacral morphology and to derive a practically applicable discriminant function formula for sex estimation.

A total of 20 three-dimensional landmarks were digitised on a sample of 200 sacra from a sample of South Africans of African descent (Black South Africans) with ages ranging between 20 and 90years, equally distributed for sex.

Geometric morphometric methods were used to analyse sacral morphology and sexual dimorphism as it captures size-independent shape variation and three-dimensional morphology.

Size-independent shape analysis revealed four sacral structures and metrics that account for most of its shape variation. When these were compared between the sexes, we found that sacral curvature pattern, rather than depth, differed between sexes contribute to our understanding of sacral dimorphism and will assist in forensic casework.This study investigated genetic linkage, recombination fractions and mutation rates of 16 X chromosomal short tandem repeat (X-STR) markers using a recently developed multiplex PCR assay for Sinhalese population of Sri Lanka, by analyzing 81 three-generation families including 81 grandfathers with daughters and 162 grandsons. In addition, 31 two generation families involving mother father daughter trios were included for mutation analysis. The analysis of recombination fractions between marker pairs identified two linkage blocks (maximum LOD scores > 3.0) each spanning a physical distance of 44.35 Mb and 6.04 Mb respectively. Though recombination events are usually rare among closely linked markers, crossovers were observed for markers located  less then  1.0 Mb apart. The recombination fractions observed are not fully concordant with those reported earlier, including the second-generation Rutgers combined linkage-physical map. This suggests that linkage is not uniform among different populations. However, the overall and marker-specific mutation rates of the present study did not differ from previous reports, though it needs confirmation with a much larger sample set. The findings presented here will provide the baseline information required for biostatistical calculations conducted using X-STR markers, in complex kinship analysis of Sinhalese population.Human identification plays a significant role in the investigations of disasters and criminal cases. Human identification could be achieved quickly and efficiently via 3D sphenoid sinus models by customized convolutional neural networks. https://www.selleckchem.com/EGFR(HER).html In this retrospective study, a deep learning neural network was proposed to achieve human identification of 1475 noncontrast thin-slice CT scans. A total of 732 patients were retrieved and studied (82% for model training and 18% for testing). By establishing an individual recognition framework, the anonymous sphenoid sinus model was matched and cross-tested, and the performance of the framework also was evaluated on the test set using the recognition rate, ROC curve and identification speed. Finally, manual matching was performed based on the framework results in the test set. Out of a total of 732 subjects (mean age 46.45 years ± 14.92 (SD); 349 women), 600 subjects were trained, and 132 subjects were tested. The present automatic human identification has achieved Rank 1 and Rank 5 accuracy values of 93.94% and 99.24%, respectively, in the test set. In addition, all the identifications were completed within 55 s, which manifested the inference speed of the test set. We used the comparison results of the MVSS-Net to exclude sphenoid sinus models with low similarity and carried out traditional visual comparisons of the CT anatomical aspects of the sphenoid sinus of 132 individuals with an accuracy of 100%. The customized deep learning framework achieves reliable and fast human identification based on a 3D sphenoid sinus and can assist forensic radiologists in human identification accuracy.
The purpose of this study was to compare the outcome of the piezo-assisted turbinoplasty with a partial turbinectomy technique in the treatment of chronic nasal obstruction due to inferior turbinate enlargement.

This is a prospective randomized single-center study in a cohort of 100 consecutive patients which underwent external septorhinoplasty and concomitant hybrid type of turbinoplasty.

Patients were randomly assigned into two groups. The first group included 50 patients who underwent piezo-assisted outfracturing of the inferior turbinates in combination with bipolar coagulation. The second group included 50 patients who underwent a treatment based on turbinate bipolar coagulation and partial resection of the inferior border of the turbinate. The severity of nasal obstruction was measured in both patient groups with a patient-related outcome questionnaire (NOSE) and objective measures (anterior rhinomanometry and acoustic rhinometry). Assessments were conducted prior to surgery and 3 months after thee-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors www.springer.com/00266 .
We conducted this study to describe the feasibility of high-resolution ultrasound (HRUS) in characterizing a breast implant in patients receiving an implant-based augmentation mammaplasty.

The current study was conducted in a total of 612 patients (n=612) receiving an implant-based augmentation mammaplasty at other hospitals between August 31, 2017 and August 31, 2020. Of these, 136 patients (n=136; 272 breasts) receiving reoperation were included in the current study. We compared between the patients' subjective awareness of a breast implant and its HRUS findings and an agreement between HRUS findings of a breast implant and its findings at reoperation.

The proportion of the patients receiving a silicone gel-filled breast implant was increased from 65.44% (89/136) to 81.61% (111/136) on HRUS. Moreover, HRUS was effective in identifying a manufacturer of the device.

In conclusion, our results indicate that HRUS is feasible in characterizing a breast implant in patients receiving an implant-based augmentation mammaplasty. But further prospective, large-scale studies are warranted to corroborate our results.

Following health notification by the FDA in 2008 of serious complications with transvaginal mesh for anterior pelvic organ prolapse, there has been a return to native tissue repairs. Earlier work with a self-retaining support (SRS) implant showed a high anatomical success rate with minimal implant-related complications over a medium-term follow-up. It is proposed that post-implant complications are more a consequence of the method of mesh anchoring rather than the implant itself. Our system incorporates an ultralight mesh with a frame that provides level I, II, and III support without the need for fixation. The first long-term outcomes of SRS implantation are presented.

A prospective multicenter trial was conducted using two consecutive identical protocols of the use of the SRS implant in women with symptomatic anterior compartment prolapse extending their follow-up to 36months. Anatomical success (Pelvic Organ Prolapse Quantification stage 0 or 1 or a Ba ≤ -2) was recorded along with subjective success a minimal risk of complications or need for reintervention.
Although D2 lymphadenectomy is currently considered a standard procedure for advanced gastric cancer (GC) worldwide, there is room for discussion about the appropriate range of suprapancreatic D2 lymphadenectomy. Focusing on the posterior hepatic plexus (PHP), which is not well recognized, we developed a surgical technique of suprapancreatic D2 lymphadenectomy, which we have called PHP-D2, and its short-term and long-term efficacies were evaluated in comparison with non-PHP-D2.

GC patients who underwent distal gastrectomy with D2 lymphadenectomy between July 2006 and May 2013 were enrolled, from which patients who had peritoneal metastasis and/or were peritoneal cytology-positive during surgery were excluded. Their medical records were retrospectively reviewed.

Ninety-two patients (non-PHP-D2 48, PHP-D2 44) were enrolled. Shorter operation time (330min vs 275min, p < 0.0001) and less blood loss (290mL vs 125mL, p < 0.0001) were observed in PHP-D2, and no pancreatic fistulas were observed in PHP-D2. More lymph nodes of #11p (1 vs 1.5, p = 0.0328) and #12a lymph nodes (0 vs 1, p = 0.0034) were retrieved in PHP-D2, with no significant differences in #8a and #9 lymph nodes. Lymphatic recurrence was significantly less in PHP-D2 (p = 0.0166), and univariate and multivariate analyses showed that non-PHP-D2 was a significant risk factor for lymphatic recurrence (p = 0.0158), although there were no significant differences between non-PHP-D2 and PHP-D2 in 5-year overall survival and 5-year relapse-free survival.

PHP-D2 was a safe and feasible procedure that had the potential to reduce lymphatic recurrence, and it can be a standard procedure of D2 lymphadenectomy for advanced GC.

The best approach for minimally invasive adrenalectomy is still under debate.

A systematic search of randomized clinical trials was carried out. A frequentist random-effects network meta-analysis was made reporting the surface under the cumulative ranking (SUCRA). The primary endpoint regarded both in-hospital mortality and morbidity. The secondary endpoints were operative time (OP), blood loss (BL), length of stay (LOS), conversion, incisional hernia, and disease recurrence rate.

Eight studies were included, involving 359 patients clustered as follows 175 (48.7%) in the TPLA arm; 55 (15.3%) in the RPLA arm; 10 (2.8%) in the Ro-TPLA arm; 25 (7%) in the TPAA arm; 20 (5.6%) in the SILS-LA arm; and 74 (20.6%) in the RPA arm. The RPLA had the highest probability of being the safest approach (SUCRA 69.6%), followed by RPA (SUCRA 63.0%). TPAA, Ro-TPLA, SILS-LA, and TPLA have similar probability of being safe (SUCRA values 45.2%, 43.4%, 43.0%, and 38.5%, respectively). Analysis of the secondary endpoints confirmed the superiority of RPA regarding OP, BL, LOS, and incisional hernia rate.

The best choice for patients with adrenal masses candidate for minimally invasive surgery seems to be RPA. An alternative could be RPLA. The remaining approaches could have some specific advantages but do not represent the first minimally invasive choice.

Inferior vena cava (IVC) leiomyosarcomas (LMS) are a rare group of retroperitoneal tumors. R0 surgical resection is the only curative modality of treatment. IVC resection for retroperitoneal sarcoma is a complex surgery with no definitive guidelines for reconstruction.

Retrospective review of all patients who underwent surgical resection of primary leiomyosarcoma of the IVC requiring resection from 2010 to 2020 at our tertiary care center was performed.

Among 24 patients who required IVC resection for LMS, only 7 (29%) required reconstruction of IVC. According to Clavien-Dindo classification, there was one grade 3 or more morbidity and 1 post-operative mortality. Seventeen patients underwent R0 resection whereas 7 patients had R1 resection on final histopathology. At a median follow-up of 25months (range 8-91months), the median OS was 40months with median DFS of 28months. Two patients presented with local recurrence while 13 patients developed systemic recurrence on follow-up.

Careful preoperative multidisciplinary planning can make IVC resection without reconstruction feasible with acceptable perioperative morbidity, mortality, and oncological outcomes for IVC LMS.

While paraaortic lymph node (PAN) dissection (PAND) has been found to be efficacious for patients with extensive lymph node metastasis (ELM) of locally advanced gastric cancer (LGC), the optimal indications for PAND remain to be elucidated. link3 Thus, the prognostic factors among these patients were evaluated.

A total of 35 patients with ELM of LGC who underwent gastrectomy with D2 and PAND between August 2008 and December 2019 were included and evaluated for long-term outcomes and prognostic factors.

Preoperative chemotherapy was administered to 33 patients [neoadjuvant chemotherapy (NAC), n = 26; palliative chemotherapy followed by conversion surgery, n = 7], none of whom suffered surgical mortality. The pathological analysis identified PAN metastasis in 11 patients (31.4%). The 5-year overall and relapse-free survival (RFS) survival were 66.4% and 52.6%, respectively. Locoregional recurrence was found in one patient. The multivariate analysis revealed that NAC (P = 0.011) and < 3 metastatic PANs on preoperative imaging (P = 0.017) were independently associated with RFS.

D2 and PAND after NAC can be a promising approach for patients with ELM of LGC. In particular, patients with a limited number of metastatic PANs can be considered good candidates for PAND.

The most affected clinical domain of the disease determines the therapeutic approach. We report the case of a 34-year-old man with all six crucial domains of psoriatic arthritis (psoriasis, peripheral arthritis, axial skeletal manifestations, dactylitis, nail changes, and enthesitis) treated unsuccessfully with conventional synthetic DMARDs, NSAID's, and steroids as well as topical treatment and phototherapy. With golimumab as the first line of bDMARD partial remission was achieved. After 24 months the treatment was switched to secukinumab due to secondary inefficacy. The psoriasis and psoriatic arthritis relapsed after 21 months of treatment with secukinumab. The patient was cycled to ixekizumab with an excellent result. IL-17A inhibitor cycling may be a successful treatment option in some difficult to treat psoriatic arthritis patients.Small-molecule metabolism has been extensively studied in the past decades, notably driven by the development of new pharmaceutical ingredients. The understanding of metabolism is critical to the anticipation of reactive metabolite formation in vivo that is often associated with toxicity. Electrochemistry has been proposed to simulate the oxidoreductive metabolism reaction catalyzed by cytochrome P450, a family of microsomal enzymes strongly involved in xenobiotic metabolism. The implementation of an electrochemical cell online with mass spectrometry allows for the fast formation and identification of the reaction end products. link3 This study discusses the ability of the synthetic electrochemical approach to simulate a complex lactamization reaction that involves the formation of reactive metabolites. Aristolochic acid I was used as a model molecule to evaluate the ability of electrochemical simulation to generate nitroso, hydroxylamine, N-hydroxylactam, lactam, and nitrenium ion metabolites.
The Fundamental Use of Surgical Energy (FUSE) program was developed by The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) to promote the safe use of surgical energy. A curriculum that could be used in hospital educational programs was needed to expand access. The goal of this project was to develop a short, inexpensive, online module that emphasizes key FUSE learning objectives. The accompanying survey assessed perceived relevancy.

The SAGES FUSE Committee developed the Hospital Compliance Module. The target audience included all OR personnel. The Module was piloted at Beth Israel Deaconess Medical Center. The data were analyzed using Chi-square with Yates' correction two-tailed test.

Three-hundred-eighty individuals completed the survey 198 (52%) surgeons, 139 (37%) nurses, 28 (7%) surgical technicians, and 15 (4%) house staff. For "…the Module taught me valuable information" 155 (41%) responded extremely and 350 (92%) responded at least somewhat. For "As a result of [the Module] how likely are you to change how you set up or use energy devices…?" 103 (27%) responded extremely and 305 (80%) responded at least somewhat. For "How likely are you to recommend this compliance module…?" 143 (38%) responded extremely and 333 (88%) responded at least somewhat.

The FUSE Hospital Compliance Module is effective and efficient. It should be considered for widespread distribution by hospitals to enhance staff education.

To evaluate a conceptually simple model to predict new-baseline-glomerular-filtration-rate (NBGFR) after radical nephrectomy (RN) based on split-renal-function (SRF) and renal-functional-compensation (RFC), and to compare its predictive accuracy against a validated non-SRF-based model. RN should only be considered when the tumor has increased oncologic potential and/or when there is concern about perioperative morbidity with PN due to increased tumor complexity. In these circumstances, accurate prediction of NBGFR after RN can be important, with a threshold NBGFR > 45ml/min/1.73m
correlating with improved overall survival.

236 RCC patients who underwent RN (2010-2012) with preoperative imaging (CT/MRI) and relevant functional data were included. NBGFR was defined as GFR 3-12months post-RN. SRF was determined using semi-automated software that provides differential parenchymal-volume-analysis (PVA) from preoperative imaging. Our SRF-based model was Predicted NBGFR = 1.24 (× Global GFR

The purpose of the study was to utilize a large-scale biomorphometric computer tomography (CT) database to determine the desirable starting point and angle for placement of the femoral intramedullary rod in the sagittal plane.

A CT-based modeling and analytics system (SOMA, Stryker, Mahwah, NJ) was used to evaluate 1029 entire-femur CT scans. From this, 19,464 simulations were run to test whether a 20cm intramedullary rod, with a radius of 4mm, would successfully pass through the femoral canal before contacting cortical bone. First, modelling included varying angles from 0-6 degrees in the sagittal plane, at 1-degree intervals. Next, the start point was adjusted with an assumed 3 degrees of induced flexion in comparison to the mechanical axis.

A total of 5012 simulations were able to place the femoral intramedullary rod 20cm into the canal. The angle of the rod that created the highest proportion of successful jig placement was at a 3-degree angle of induced flexion to the orthogonal plane of the transepicondylar axis (TEA), with 33.7% successful jig placements. The starting point for the greatest proportion of successful guide placements was 48.5% along the distance between the sTEA, slightly closer to the lateral side. In the AP plane, the average distance to the ideal start point was 12.1mm anterior to the PCL.

By examining over a thousand femoral CT scans, an angle of 3 degrees of induced flexion was identified in the sagittal plane with the highest proportion of successful placement of an intramedullary rod before cortical contact. It is important to note the high rate of failure in completely inserting the 20mm rod.
