Abstract
OBJECTIVES To comprehensively examine the characteristics and prognosis of bilateral sudden sensorineural hearing loss (BSSHL) and its subtypes compared to unilateral sudden sensorineural hearing loss (USSHL). DATA SOURCES PubMed, Scopus, and CINAHL. REVIEW METHODS Databases were searched from inception to December 5, 2023, for studies reporting patient characteristics and audiometric outcomes for BSSHL and its simultaneous (Si-BSSHL) and sequential (Se-BSSHL) subtypes. Meta-analysis of continuous measures, proportions (%), mean differences (Δ), and odds ratio (OR) were performed. RESULTS Eleven studies were included, consisting of 368 patients with BSSHL and 2,705 patients with USSHL. The pooled prevalence among all SSHL cases was 88.1% (95% CI: 81.2%-93.6%) for USSHL and 11.9% (95% CI: 6.4% to 18.8%) for BSSHL. PTA improvement following treatment with steroids was significantly worse in patients with BSSHL (Δ15.3 dB; 95% CI: 14.6 to 15.9; p < 0.0001) compared to patients with USSHL. There was no significant difference in post-treatment PTA improvement between the BSSHL subtypes. Patients with Si-BSSHL were significantly less likely to have an idiopathic etiology (OR: 0.4; 95% CI: 0.2 to 0.8; p = 0.01) and significantly more likely to have an autoimmune disease etiology (OR: 27.4; 95% CI: 2.2 to 336.1; p = 0.01), comorbid cardiovascular disease (OR: 2.3; 95% CI: 1.1 to 5.1; p = 0.03), and comorbid hypertension (OR: 2.5; 95% CI: 1.6 to 3.8; p < 0.0001) compared to patients with USSHL. CONCLUSIONS BSSHL is a considerably rarer form of SSHL with worse prognosis compared to USSHL. BSSHL, and Si-BSSHL in particular, has significantly greater associations with systemic pathologies compared to USSHL. Laryngoscope, 2024.

Abstract
Ipsilateral hip and knee dislocation is a rare and complex injury that usually results from high-energy trauma. Only 14 cases were reported in the literature so far. We report the case of a 35-year-old man who presented with an ipsilateral right hip and knee dislocation after being involved in a road traffic accident. A contralateral floating knee was associated. The hip dislocation was associated to a posterior wall fracture of the acetabulum and a femoral head fracture. The knee dislocation was compound and associated with a patella fracture. The hip dislocation was reduced. The posterior wall and the femoral head fractures were treated conservatively. The knee dislocation was reduced and stabilized by external fixator. Early postoperative infection occurred and was treated surgically. At the last follow-up, the knee was ankylosed at 5° of flexion with a bony bridge between the femoral condyle and the tibial plateau. The patient described an occasional hip pain on exertion. He had full range of motion of the right hip. No avascular necrosis of the femoral head was seen. Outcomes of simultaneous hip and knee dislocation are very variable and remain unpredictable. The timing of reducing the hip joint and the knee.

Abstract
In this paper, we reported the first case of mirrored spontaneous intracranial hemorrhage with almost identical hematoma morphological characteristics. This patient's first symptom was loss of consciousness, without any local neurological symptoms. This clinical presentation fits well with the atypical computed tomography (CT) image showing bilateral hematomas, and indicates that the distribution of hypertensive vascular damage may be symmetric and that the degree of the bilateral lesions may be similar.

Abstract
Total knee arthroplasty is one of the most common orthopedic procedures. Simultaneous bilateral knee arthroplasty involves performing total knee arthroplasty on both knees in a single anesthetic session. This systematic review and meta-analysis followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020. A primary search was performed using PubMed, EBSCO, Scopus, Web of Science, Clarivate, and Google Scholar databases. Quantitative data synthesis was performed using MedCalc® Statistical Software version 20.115 to determine the pooled prevalence of the infection among patients who underwent simultaneous bilateral knee arthroplasty. The Newcastle-Ottawa Scale was used to assess study quality. We included 30 studies in our quantitative data synthesis, with a total population of 118,502 patients (237,004 knees). The pooled prevalence of superficial infection, deep infection, and unspecified surgical site infection was estimated to be 0.86% (95% confidence interval: 0.62-1.13%), 0.84% (95% confidence interval: 0.64-1.05%), and 1.18% (95% confidence interval: 0.45-2.27%), respectively. There was significant heterogeneity (I2 >50%) in all analyses, and inspection of funnel plots revealed a symmetrical distribution of plotted data. We found that the infection rates following simultaneous bilateral knee arthroplasty were relatively low but heterogeneous, as the data showed marked variability. Superficial infections were more common than deep infections; however, there was a small difference in their prevalence. Furthermore, the reliability of our findings was limited owing to significant heterogeneity.

Abstract
Patients on long-term anticoagulation therapy require frequent testing of prothrombin time/international normalized ratio (PT/INR) to ensure therapeutic efficacy. Point-of-care (POC) PT tests for at-home monitoring eliminate the burden of visiting the clinic, but realizing a cost-effective and robust at-home POC test for PT has remained elusive. Recent demonstrations of printed PT sensors show promise for addressing the cost concerns; however, the printed sensors have lacked quality control to ensure reliability between tests. In this work, on-chip redundancy is introduced with fully printed impedimetric PT sensors by incorporating simultaneous testing with a single fingerstick volume of blood (8 μL). The influence of electrode dimensions and composition were studied, revealing an optimal electrode spacing of 200 μm and an unexpected dependence on the morphology of the electrodes. Three distinct silver morphologies were studied: aerosol jet printed silver nanoparticles (AgNPs), aerosol jet printed silver nanowires (AgNWs), and evaporated silver (Ag). In general, AgNPs exhibited the best PT sensor performance, due to relatively low conductance and high porosity. Overall, the printed impedimetric PT sensor functionalization was improved by incorporating simultaneous testing and, when combined with a handheld control device, shows promise for leading to a system that overcomes the challenges of commercial PT/INR coagulometers.

Abstract
BACKGROUND Patients who have bilateral hip arthritis can be treated with bilateral total hip arthroplasty (bTHA) in either a staged or simultaneous fashion. The goal of this study was to determine whether staged and simultaneous posterior bTHA patients differ in regard to (1) patient-reported outcome measures, (2) 90-day complication rates, and (3) discharge dispositions and cumulative lengths of stay. METHODS Patients who (1) underwent simultaneous bTHA or staged bTHA (within 12 months) using the posterior approach, and (2) completed preoperative and 1-year postoperative Hip dysfunction and Osteoarthritis Outcome Score for Joint Replacement surveys were included in the study. A total of 266 patients (87 simultaneous bTHA and 179 staged bTHA) were included. Chart review was performed to collect patient-level variables, postoperative complications, discharge dispositions, and lengths of stay. RESULTS Staged bTHA patients had higher Hip dysfunction and Osteoarthritis Outcome Score for Joint Replacement, Lower Extremity Activity Scale, and Veterans RAND 12-Item Health Survey physical component scores compared to simultaneous bTHA patients at 6 weeks after surgery (P = .019, .006, and .008, respectively), but these differences did not meet the minimal clinically important difference threshold for any questionnaire. Simultaneous bTHA was associated with higher rate of periprosthetic fractures (P = .034) and discharge to a location other than home (P < .001). CONCLUSIONS There were statistically significant, but likely not clinically meaningful differences in patient-reported outcomes for staged and simultaneous bTHA patients at 6 weeks after surgery. Surgeons should be aware of the higher periprosthetic fracture risk and greater likelihood of discharge to a rehabilitation facility associated with simultaneous bTHA. Further research should aim to understand which patients may benefit most from simultaneous bTHA.

Abstract
Deadwood provides habitat for fungi and serves diverse ecological functions in forests. We already have profound knowledge of fungal assembly processes, physiological and enzymatic activities, and resulting physico-chemical changes during deadwood decay. However, in situ detection and identification methods, fungal origins, and a mechanistic understanding of the main lignocellulolytic enzymes are lacking. This study used metaproteomics to detect the main extracellular lignocellulolytic enzymes in 12 tree species in a temperate forest that have decomposed for 8 ½ years. Mainly white-rot (and few brown-rot) Basidiomycota were identified as the main wood decomposers, with Armillaria as the dominant genus; additionally, several soft-rot xylariaceous Ascomycota were identified. The key enzymes involved in lignocellulolysis included manganese peroxidase, peroxide-producing alcohol oxidases, laccase, diverse glycoside hydrolases (cellulase, glucosidase, xylanase), esterases, and lytic polysaccharide monooxygenases. The fungal community and enzyme composition differed among the 12 tree species. Ascomycota species were more prevalent in angiosperm logs than in gymnosperm logs. Regarding lignocellulolysis as a function, the extracellular enzyme toolbox acted simultaneously and was interrelated (e.g. peroxidases and peroxide-producing enzymes were strongly correlated), highly functionally redundant, and present in all logs. In summary, our in situ study provides comprehensive and detailed insight into the enzymatic machinery of wood-inhabiting fungi in temperate tree species. These findings will allow us to relate changes in environmental factors to lignocellulolysis as an ecosystem function in the future.

Abstract
Background Keratoconus (KC) is degenerative corneal disorder, with central and paracentral thinning and corneal ectasia. For KC progressive cases, primary treatment included corneal collagen cross linking (CXL) to stabilize coning and intracorneal rings segment (ICRS) to correct visual acuity. Aim The aim of the study is to assess efficacy and safety of ICRS and CXL on one session (Simultaneous) or two sessions (sequential) with maximum of 1 month apart. Patients and Methods This Prospective Intervention Comparative research made at Armed forces hospital, Cairo, Egypt from January 2017 to December 2019. Forty patients (60 eyes) with mild to moderate KC were enrolled. Patients sorted into Simultaneous group includes 21 patients (30 eyes) undergo two procedures (ICRS then CXL) at the same session and Sequential group included 19 patients (30 eyes) undergo ICRS then CXL on two sessions with month apart. Patients followed up at end of 1st, 3rd, and 6th months. Assessment included changes in corrected corneal surface irregularities as minimum keratometric 1 (K1), maximum keratometric readings (K2), and mean keratometric (Km) readings. Results Improvement of K1, K2, and Km in Simulations and Sequential groups achieved at end of 1st-, 3rd-, and 6th-month postoperative versus preoperative. Maximum improvement in Simulations and Sequential groups in K1 achieved at end of 6th and 1st months, in K2 at end of 3rd and 6th months and in Km at end of 1st and 3rd months. Conclusions Combined ICRS and CXL act safely in one or two sessions and there are no statistically significant variations between results on both methods in keratometric readings.

Abstract
Bilateral total knee arthroplasty (BTKA) is a common intervention for bilateral knee osteoarthritis, and the choice between simultaneous (SimBTKA) and staged (StaBTKA) procedures remains a critical decision. This meta-analysis systematically reviews and analyzes the existing literature to compare mortality outcomes associated with SimBTKA and StaBTKA. A comprehensive search was conducted across major databases for studies reporting mortality outcomes in SimBTKA and StaBTKA. Inclusion criteria encompassed studies published up to the cutoff date of January 2023, and a total of 37 studies were included in the quantitative synthesis. Meta-analysis was performed using a random-effects model to calculate odds ratios (ORs) with 95% confidence intervals (CIs) using the Review Manage 5.4 software. The meta-analysis included 86,333 SimBTKA cases and 115,146 StaBTKA cases. The overall mortality rate in SimBTKA was 0.66%, while StaBTKA's was 0.43%. The pooled OR for mortality in SimBTKA versus StaBTKA was 1.55 [1.16, 2.08], indicating a statistically significant higher mortality risk in SimBTKA. Our findings suggest that SimBTKA is associated with an increased risk of mortality compared to StaBTKA. This meta-analysis provides valuable insights into the comparative mortality outcomes of SimBTKA and StaBTKA. While SimBTKA may offer potential advantages, including a single anesthesia event and shorter recovery time, clinicians should consider the increased mortality risk associated with this approach. Future research should focus on prospective studies with standardized reporting to further elucidate the nuanced factors influencing mortality outcomes in bilateral knee arthroplasty.

Abstract
OBJECTIVE Carpal tunnel syndrome (CTS) presents bilaterally in nearly 60%-70% of affected patients. Bilateral carpal tunnel release (CTR) can be performed in a staged or simultaneous fashion. There remains a limited understanding of the optimal preoperative factors to use for patient selection when determining simultaneous versus staged bilateral CTR. Moreover, it is unclear how these factors influence postoperative outcomes. In this study, the authors aimed to identify and compare preoperative comorbidities and postoperative outcomes in patients who had undergone simultaneous versus staged open and endoscopic bilateral CTR. METHODS The authors performed a retrospective analysis of data collected from the TriNetX database. Patients with bilateral CTS who had been treated from February 1, 2002, to February 1, 2022, were dichotomized by their bilateral release approach: simultaneous or staged within 3 months. The resulting groups were analyzed separately by open versus endoscopic techniques. Next, cohorts were analyzed for preoperative comorbidities to identify possible factors for surgical determination. Then, they were propensity score matched on demographics and comorbidities. Postoperative outcomes within 6 months of surgery were measured with and without matching. RESULTS After matching, 9286 and 3709 patients remained in the open and endoscopic groups, respectively. Those who had undergone staged surgeries via an open or endoscopic approach had more preoperative comorbidities. After matching, staged open release was associated with significantly higher rates of postprocedural care, hand/joint pain, limb pain, trigger finger, and upper respiratory tract infections. Simultaneous open release was associated with higher rates of emergency room visits. Staged endoscopic release was associated with significantly higher rates of postprocedural care, limb pain, and trigger finger. No significant outcomes were favored in the simultaneous endoscopic group. CONCLUSIONS Before matching, patients who had undergone staged CTR had significantly higher rates of preoperative medical comorbidities compared with patients in the simultaneous CTR group. Moreover, staged CTR was significantly associated with higher rates of postoperative complications. After matching on demographics and comorbidities, staged CTR was still associated with higher rates of postoperative complications, suggesting that preoperative comorbidities do not influence postoperative outcome. Further prospective studies could be used to validate these results and provide new findings for the management and treatment of these groups.

Abstract
The objective of this study is to review our experience with simultaneous bilateral cochlear implantation (BiCI) in adults, and assess its feasibility. This could shorten the time required to regain binaural hearing, prevent social isolation, and potentially eliminate the need for hearing aids, as seen with sequential BiCI. A retrospective study was conducted involving adult patients who received simultaneous BiCI at our center between 2010 and 2023. The feasibility of simultaneous BiCI was assessed through postoperative clinical evaluations, outpatient visits, discharge status, and the acceptance of device fitting. Twenty-seven patients underwent simultaneous BiCIs. Their mean age was 37 years, comprising 59.3% males and 40.7% females. Out of the included patients, 51.9% had childhood-onset hearing loss, while 29.6% developed hearing loss later in life. Causes of hearing loss included meningitis 7.4%, trauma 11.1%, non-specific high-grade fever 11.1%, and Brucellosis infection 3.7%. Labyrinthine ossificans (LO) was present in 7.4%, and retrofenestral otospongiosis in 3.7%. The post-operative period and initial outpatient visit were uneventful for 88.8% and 81.5% of patients, respectively. Intraoperative complications were absent in 96.2% of cases. Simultaneous BiCI is feasible in adults without major intraoperative complications or troublesome recovery periods, offering potential benefits by reducing the number of surgeries and hospital admissions compared to the sequential method.

Abstract
In this work, we introduce a super-resolution method that generates a high-resolution (HR) sodium (23 Na) image from simultaneously acquired low-resolution (LR) 23 Na density-weighted MRI and HR proton density, T1 , and T2 maps from proton (1 H) MR fingerprinting in the brain at 7 T. The core of our method is a partial least squares regression between the HR (1 H) images and the LR (23 Na) image. An iterative loop and deconvolution with the point spread function of each acquired image were included in the algorithm to generate a final HR 23 Na image without losing features from the LR 23 Na image. The method was applied to simultaneously acquired HR proton and LR sodium data with in-plane resolution ratios between sodium and proton data of 3.8 and 1.9 and the same slice thickness. Four volunteers were scanned to evaluate the method's performance. For the data with a resolution ratio of 3.8, the mean absolute difference between the generated and ground truth HR 23 Na images was in the range of 1.5%-7.2% of the ground truth with a multiscale structural similarity index (M-SSIM) of 0.93 ± 0.03. For the data with a resolution ratio of 1.9, the mean absolute difference was in the range of 4.8%-6.3% with an M-SSIM of 0.95 ± 0.01.

Abstract
OBJECTIVE To analyze the clinical effect of endoscopy-assisted functional rhinoplasty. METHODS Endoscopy-assisted functional rhinoplasty was performed in all patients. Deviated nasal septum was corrected, nasal septum cartilage graft was prepared through open access under the assistance of endoscopy, the nasal frame structure was adjusted with the endoscopy-assisted rhinoplasty combined with middle and inferior turbinoplasty, and the patient's nasal ventilation function and external nose cosmetology were restored. Visual Analogue Scale (VAS), Nasal Obstruction Symptom Evaluation (NOSE), nasal acoustic reflex, and nasal resistance were examined preoperatively and 6 months postoperatively. Rhinoplasty Outcome Evaluation (ROE), nasal appearance deviation value, and morphological measurement of the external nose were used to assess the external nasal appearance. Finally, postoperative satisfaction was used for overall evaluation. RESULTS In terms of nasal ventilation evaluation, the VAS and NOSE scores of nasal obstruction decreased significantly at 6 months after the operation compared with that before the operation (1.96 ± 0.84 vs 6.68 ± 1.28, 4.25 ± 1.80 vs 12.25 ± 2.50; P < .05). Among the objective indexes, MCA1, MCA2 and NV5 were significantly increased whereas RT, MCA1a/MCA1b, MCA2a/MCA2b, MD1a/MD1b, and MD2a/MD2b were significantly decreased compared with those before the operation (P < .05). The MD1 and MD2 levels before and after operation had no significant differences (P > .05). In the evaluation of external nose morphology, postoperative ROE was significantly increased, and the deviation value of nasal appearance was significantly decreased [(16.93 ± 2.61 vs 10.64 ± 3.01), (1.46 ± 1.11 mm vs 5.72 ± 2.30 mm), P < .05]. In terms of postoperative patient satisfaction: 26 cases (92.9%) were very satisfied with nasal ventilation function, 2 cases (7.1%) were satisfied with nasal ventilation function, 24 cases (85.7%) were very satisfied with nasal appearance, and 4 cases (14.3%) were satisfied with nasal appearance. CONCLUSIONS Nasal endoscopy-assisted functional rhinoplasty can improve the nasal ventilation function and external nasal morphology at the same time. Moreover, its clinical effect is good, and the patient satisfaction is high.

Abstract
OBJECTIVES The incidence of cholelithiasis is higher among individuals who have undergone gastric surgery. The benefits of concomitant gallbladder removal in asymptomatic gallstone patients remain uncertain. The aim was to investigate the necessity and safety of simultaneous cholecystectomy in this particular patient population. METHODS We performed a systematic review and meta-analysis to assess the incidence of asymptomatic cholelithiasis converting to symptomatic after gastric surgery and the complication rate associated with simultaneous cholecystectomy. PubMed, Embase, and the Cochrane Library were searched for relevant articles published until 10 March 202210 March 2022. RESULTS Patients with asymptomatic cholelithiasis after gastric surgery were at a higher risk of developing symptomatic cholelithiasis compared to those without cholelithiasis (relative risk [RR] 2.28, 95% confidence interval [CI] 1.23-4.25) and those with unknown gallbladder conditions (RR 2.70, 95% CI 1.54-4.73). Additionally, patients who underwent simultaneous cholecystectomy did not face a higher risk of complications compared to those who only underwent gastric surgery (RR 0.86, 95% CI 0.48-1.53). CONCLUSIONS Simultaneous cholecystectomy is both necessary and safe for patients with asymptomatic cholelithiasis undergoing gastric surgery. It is crucial to assess the gallbladder's condition before gastric surgery, and if the gallbladder status is unknown, simultaneous cholecystectomy should be avoided.

Abstract
In multi-analyte extractions, tissue is typically homogenized in a lysis buffer, and then DNA, RNA, and protein are purified from the supernatant. However, yields are typically lower than in dedicated, single-analyte extractions. In a two-part experiment, we assessed whether yields could be improved by revisiting the normally discarded, post-homogenized tissue debris. We initially performed additional homogenizations, each followed by a simultaneous extraction. These yielded no additional RNA, 13% additional DNA (which became progressively more degraded), and 161.7% additional protein (which changed in proteome when analyzed using SDS-PAGE). We then digested post-homogenized tissue debris from a simultaneous extraction using proteinase K and extracted DNA using silica spin columns or alcohol precipitation. An average additional DNA yield of 27.1% (silica spin columns) or 203.9% (alcohol precipitation) was obtained with/without compromising DNA integrity (assessment by long-range PCR, DNA Integrity Numbers, and size at peak fluorescence of electropherogram). Validation using a cohort of 65 tissue blocks returned an average additional DNA yield of 31.6% (silica columns) and 54.8% (alcohol precipitation). Users can therefore refreeze the homogenized remnants of tissue blocks rather than disposing of them and then perform additional DNA extractions if yields in the initial multi-analyte extractions were low.

Abstract
Near-infrared fluorescence (NIRF) image-guided surgery is a useful tool that can help reduce perioperative complications and improve tissue recognition. Indocyanine green (ICG) dye is the most frequently used in clinical studies. ICG NIRF imaging has been used for lymph node identification. However, there are still many challenges in lymph node identification by ICG. There is increasing evidence that methylene blue (MB), another clinically applicable fluorescent dye, can also be useful in the intraoperative fluorescence-guided identification of structures and tissues. We hypothesized that MB NIRF imaging could be used for lymph node identification. The aim of this study was to evaluate the feasibility of intraoperative lymph node fluorescence detection using intravenously (IV) administered MB and compare it to ICG via a camera that has two dedicated near-infrared (NIR) channels. Three pigs were used in this study. ICG (0.2 mg/kg) was administered via a peripheral venous catheter followed by immediate administration of MB (0.25 mg/kg). NIRF images were acquired as video recordings at different time points (every 10 min) over an hour using the QUEST SPECTRUM® 3 system (Quest Medical Imaging, Middenmeer, The Netherlands), which has two dedicated NIR channels for simultaneous intraoperative fluorescence guidance. The 800 nm channel was used to capture ICG fluorescence and the 700 nm channel was used for MB. The target (lymph nodes and small bowel) and the background (vessels-free field of the mesentery) were highlighted as the regions of interest (ROIs), and corresponding fluorescence intensities (FI) from these ROIs were measured. The target-to-background ratio (TBR) was then computed as the mean FI of the target minus the mean FI of the background divided by the mean FI of the background. In all included animals, a clear identification of lymph nodes was achieved at all time points. The mean TBR of ICG in lymph nodes and small bowel was 4.57 ± 1.00 and 4.37 ± 1.70, respectively for the overall experimental time. Regarding MB, the mean TBR in lymph nodes and small bowel was 4.60 ± 0.92 and 3.27 ± 0.62, respectively. The Mann-Whitney U test of the lymph node TBR/small bowel TBR showed that the TBR ratio of MB was statistically significantly higher than ICG. The fluorescence optical imaging technology used allows for double-wavelength assessment. This feasibility study proves that lymph nodes can be discriminated using two different fluorophores (MB and ICG) with different wavelengths. The results suggest that MB has a promising potential to be used to detect lymphatic tissue during image-guided surgery. Further preclinical trials are needed before clinical translation.

Abstract
The ongoing COVID-19 pandemic highlights that complications and mortality associated with infectious diseases increase with age. Various vaccines are recommended for adults, but coverage rates remain suboptimal. Although co-administration would improve vaccine uptake and timely immunization, this is not routine practice in adults. We review key data on co-administration of vaccines in children and adults to reassure healthcare providers about its safety and advantages. In European countries and the United States, combined tetanus, diphtheria, and acellular pertussis boosters as well as meningococcal and human papillomavirus vaccines are recommended for healthy adolescents and adults of certain ages. Vaccination against influenza (annually), pneumococcal disease, and herpes zoster is recommended for older adults and specific risk groups. While co-administration is well established in children, it is less common in adults. Travelers can also receive multiple co-administered vaccines. Pediatric and travel vaccine co-administration has a well-established positive benefit-risk profile and is an efficient and cost-saving strategy to improve coverage. Healthcare providers could more often recommend and practice vaccine co-administration; this would not risk patient safety and health, would improve protection against vaccine-preventable diseases, and would help comply with national vaccination calendars. Recommending bodies may consider revising vaccination schedules to reduce the number of visits.

Abstract
Evaluation and understanding of the thermal behavior of polymers is crucial for many applications, e.g., polymer processing at relatively high temperatures, and for evaluating polymer-polymer miscibility. In this study, the differences in the thermal behavior of poly(vinyl alcohol) (PVA) raw powder and physically crosslinked films were investigated using various methods, such as thermogravimetric analysis (TGA) and derivative TGA (DTGA), differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). Various strategies were adopted, e.g., film casting from PVA solutions in H2O and D2O and heating of samples at carefully selected temperatures, in order to provide insights about the structure-properties relationship. It was found that the physically crosslinked PVA film presents an increased number of hydrogen bonds and increased thermal stability/slower decomposition rate compared to the PVA raw powder. This is also depicted in the estimated values of specific heat of thermochemical transition. The first thermochemical transition (glass transition) of PVA film, as for the raw powder, overlaps with mass loss from multiple origins. Evidence for minor decomposition that occurs along with impurities removal is presented. The overlapping of various effects (softening, decomposition, and evaporation of impurities) has led to confusion and apparent consistencies, e.g., from the XRD, it is derived that the film has decreased crystallinity, and apparently this is in agreement with the lower value of heat of fusion. However, the heat of fusion in this particular case has a questionable meaning.

Abstract
Humans can direct attentional resources to a single sound occurring simultaneously among others to extract the most behaviourally relevant information present. To investigate this cognitive phenomenon in a precise manner, we used frequency-tagging to separate neural auditory steady-state responses (ASSRs) that can be traced back to each auditory stimulus, from the neural mix elicited by multiple simultaneous sounds. Using a mixture of 2 frequency-tagged melody streams, we instructed participants to selectively attend to one stream or the other while following the development of the pitch contour. Bottom-up attention towards either stream was also manipulated with salient changes in pitch. Distributed source analyses of magnetoencephalography measurements showed that the effect of ASSR enhancement from top-down driven attention was strongest at the left frontal cortex, while that of bottom-up driven attention was dominant at the right temporal cortex. Furthermore, the degree of ASSR suppression from simultaneous stimuli varied across cortical lobes and hemisphere. The ASSR source distribution changes from temporal-dominance during single-stream perception, to proportionally more activity in the frontal and centro-parietal cortical regions when listening to simultaneous streams. These findings are a step forward to studying cognition in more complex and naturalistic soundscapes using frequency-tagging.

Abstract
Three different preclinical evaluation methods of MTF through-frequency response, MTF through-focus-response and expected visual acuity were used to compare and analyze the imaging differences of IOLs with four different optical designs. The research work could be used in the simultaneous vision IOLs in the optical design stage and verify the optical quality of the IOLs, the results can predict the visual representation of the patients better. The evaluation results can provide reference for IOL manufacturers and users in product design, development, validation and application selection.

Abstract
Bisphosphonates have recently been used as a first-line treatment for osteoporosis. However, prolonged bisphosphonate use may be associated with insufficiency and atypical femoral fractures. In this case report, we present a patient with simultaneous bilateral insufficiency femoral fractures after using alendronate for 11 years, which were treated surgically. Our patient also had a history of a previous right femoral atypical fracture eight years before the latest ones, while on 3-year alendronate treatment. To our knowledge, it is the first patient reported with three atypical - insufficiency fractures covering all the anatomical areas of the proximal half of the femur after long-term bisphosphonate treatment.

Abstract
Objective To evaluate the clinical characteristics of simultaneous bilateral sudden sensorineural hearing loss (Si-BSSNHL) as well as its prognostic factors. Methods Patients with Si-BSSNHL who were admitted to the Department of Otology Medicine between December 2018 and December 2021 were enrolled in the case group. Propensity score matching (PSM) for sex and age was used to select the control group, which included people who had unilateral sudden sensorineural hearing loss (USSNHL) during the same time period. Hearing recovery, audiological examinations, vestibular function assessments, laboratory tests, and demographic and clinical manifestations were analyzed for intergroup comparisons. Binary logistic regressions were used for both univariate and multivariate analyses of Si-BSSNHL prognostic factors. Results Before PSM, the Si-BSSNHL and USSNHL groups differed significantly (p < 0.05) in terms of time from onset to treatment, initial pure-tone average (PTA), final PTA, hearing gain, audiogram curve type, proportion of tinnitus, high-density lipoprotein level, homocysteine level, and effective rate. After PSM, significant differences were also observed in time from onset to treatment, initial PTA, final PTA, hearing gain, total and indirect bilirubin levels, homocysteine level, and effective rate between the two groups (p < 0.05). There was a significant difference in the classification of therapeutic effects between the two groups (p < 0.001). For prognostic analysis, the audiogram curve type was significantly different between the effective group and the ineffective groups of Si-BSSNHL (p = 0.01), in which the sloping type was an independent risk factor for the prognosis of the right ear in Si-SSNHL (95% confidence interval, 0.006-0.549, p = 0.013). Conclusion Patients with Si-BSSNHL had mild deafness, elevated total and indirect bilirubin and homocysteine levels, and poorer prognosis than those with USSNHL. Audiogram curve type was linked to the therapeutic effect of Si-BSSNHL, and the sloping type was an independent risk factor for a poor prognosis in the right ear of Si-SSNHL.

Abstract
Neurofeedback (NF) is a biofeedback technique that teaches individuals self-control of brain functions by measuring brain activations and providing an online feedback signal to modify emotional, cognitive, and behavioral functions. NF approaches typically rely on a single modality, such as electroencephalography (EEG-NF) or a brain imaging technique, such as functional magnetic resonance imaging (fMRI-NF). The introduction of simultaneous EEG-fMRI tools has opened up the possibility of combining the high temporal resolution of EEG with the high spatial resolution of fMRI, thereby increasing the accuracy of NF. However, only a few studies have actively combined both techniques. In this study, we conducted a systematic review of EEG-fMRI-NF studies (N = 17) to identify the potential and effectiveness of this non-invasive treatment for neurological conditions. The systematic review revealed a lack of homogeneity among the studies, including sample sizes, acquisition methods in terms of simultaneity of the two procedures (unimodal EEG-NF and fMRI-NF), therapeutic targets field, and the number of sessions. Indeed, because most studies are based on a single session of NF, it is difficult to draw any conclusions regarding the therapeutic efficacy of NF. Therefore, further research is needed to fully understand non-clinical and clinical potential of EEG-fMRI-NF.

Abstract
Although thermosets and various biopolymers cannot be softened without being decomposed, the vast majority of thermoplastics are believed to exhibit thermal transitions solely related to physical alterations of their structure-a behavior typical of low molecular weight substances. In this study, Differential Scanning Calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR) and Thermogravimetry (TGA) were used to study the softening of four common non-hydrogen-bonded thermoplastic polymers (polypropylene, polypropylene-grafted-maleic anhydride, poly(vinyl chloride) and polystyrene) along with a hydrogen-bonded polymer as a reference, namely, poly(vinyl alcohol). It is shown that the softening of these polymers is a thermochemical transition. Based on fundamental concepts of statistical thermodynamics, it is proposed that the thermal transition behavior of all kinds of polymers is qualitatively the same: polymers cannot be softened without being decomposed (in resemblance with their incapability to boil) and the only difference between the various types of polymers is quantitative and lies in the extent of decomposition during softening. Decomposition seems to reach a local maximum during softening; however, it is predicted that polymers constantly decompose even at room temperature and, by heating, (sensible) decomposition is not initiated but simply accelerated. The term "latent decomposition" is proposed to describe this concept.

Abstract
Common methodologies such as liquid-liquid extraction and solid-phase extraction are applied for the extraction of opioids from biological specimens i.e., blood and urine. Techniques including LC-MS/LC-MSMS, GC-MS, etc. are used for qualitative or quantitative determination of opioids. The goal of the present work is to design a green, economic, rugged, and simple extraction technique for famous opioids in human blood and urine and their simultaneous quantification by GC-MS equipped with an inert plus electron impact (EI) ionization source at SIM mode to produce reproducible and efficient results. Morphine, codeine, 6-acetylmorphine, nalbuphine, tramadol and dextromethorphan were selected as target opioids. Anhydrous Epsom salt was applied for dSPE of opioids from blood and urine into acetonitrile extraction solvent with the addition of sodium phosphate buffer (pH 6) and n-hexane was added to remove non-polar interfering species from samples. BSTFA was used as a derivatizing agent for GC-MS. Following method validation, the LOD/LLOQ and ULOQ were determined for morphine, codeine, nal-buphine, tramadol, and dextromethorphan at 10 ng/mL and 1500 ng/mL, respectively, while the LOD/LLOQ and ULOQ were determined for 6-acetylmorphine at 5 ng/mL and 150 ng/mL, respectively. This method was applied to real blood and urine samples of opioid abusers and the results were found to be reproducible with true quantification.

Abstract
Magnetic resonance signals from different nuclei can be excited or received at the same time,rendering simultaneous or rapidly interleaved multi-nuclear acquisitions feasible. The advan-tages are a reduction of total scan time compared to sequential multi-nuclear acquisitions or that additional information from heteronuclear data is obtained at thesame time and anatomical position. Information content can be qualitatively increased by delivering a more comprehensive MR-based picture of a transient state (such as an exercise bout). Also, combiningnon-proton MR acquisitions with 1 Hinformation (e.g., dynamic shim updates and motion correction) can be used to improve data quality during long scans and benefits image coregistration. This work reviews the literature on interleaved and simultaneous multi-nuclear MRI and MRS in vivo. Prominent use cases for this methodology in clinical and research applications are brain and muscle, but studies have also been carried out in other targets, including the lung, knee, breast and heart. Simultaneous multi-nuclear measurements in the liver and kidney have also been performed, but exclusively in rodents. In this review, a consistent nomenclature is proposed, to help clarify the terminology used for this principle throughout the literature on in-vivo MR. An overview covers the basic principles, the technical requirements on the MR scanner and the implementations realised either by MR system vendors or research groups, from the early days until today. Considerations regarding the multi-tuned RF coils required and heteronuclear polarisation interactions are briefly discussed, and fields for future in-vivo applications for interleaved multi-nuclear MR pulse sequences are identified.

Abstract
BACKGROUND Female gender and surgical drain use have been associated with an increased transfusion risk following single-anesthetic bilateral total knee arthroplasty (SBTKA). This study evaluated allogenic blood transfusion rates among female and male patients undergoing SBTKA with intraoperative tourniquet, tranexamic acid and contemporary blood transfusion thresholds but without surgical drain use. METHODS We performed a retrospective electronic medical record review for 125 consecutive patients undergoing SBTKA (250 knees) between May 1, 2015 and July 10, 2021. Patient demographic characteristics (age, gender, body mass index, American Society of Anesthesiologists), preoperative and postoperative hemoglobin levels, perioperative transfusions, operative time, and hospital length of stay were compared between 76 female (60.8%) and 49 male (39.2%) patient cohorts using paired Student's t-test or Fisher's exact test with a P value <.05 for significance. RESULTS No patient in either gender-based cohort received a perioperative allogeneic or autologous blood transfusion (P = 1). There were no significant differences in patient demographic features or medical comorbidities. Male patients had significantly higher mean preoperative (14.7 versus 13.7 g/dL, P < .01) and postoperative (12.7 versus 11.8 g/dL, P < .01) hemoglobin levels and a shorter mean hospital length of stay (2.5 versus 3.0 days, P < .01). There was no difference in the mean operative time (154.7 versus 150.7 minutes, P = .34) or change in the hemoglobin level (2.1 versus 1.9 g/dL, P = .27). CONCLUSION SBTKA can be performed with a limited risk of perioperative transfusion with a combination of intraoperative tourniquet, tranexamic acid, conservative blood transfusion criteria, and avoidance of postoperative drain use. Study results were not influenced by patient gender. LEVEL OF EVIDENCE This is a level III, retrospective cohort study.

Abstract
OBJECTIVES Evidence on the outcomes of simultaneous transurethral resection of bladder tumor (TURB) for bladder cancer and transurethral resection of the prostate (TURP) for obstructive benign prostatic hyperplasia is limited and contradictory. The aim of this study was to determine the oncological impact and adverse events of performing simultaneous TURB and TURP. MATERIALS AND METHODS Patients from twelve European hospitals treated with either TURB alone or simultaneous TURB and TURP (TURB+TURP) were retrospectively analyzed. A propensity-score matching (PSM) 1:1 was performed with patients from the TURB+TURP group matched to TURB-alone patients. Associations between surgery approach with recurrence-free (RFS) and progression-free (PFS) survivals were assessed in Cox regression models before and after PSM. We performed a subgroup analysis in patients with risk factors for recurrence (multifocality and/or tumor size >3cm). RESULTS A total of 762 men were included, among whom, 76% (n=581) underwent a TURB-alone and 24% (n=181) a TURB+TURP. There was no difference in terms of tumor characteristics between the groups. We observed comparable length of stay as well as complication rates including major complications (Clavien-Dindo grade ≥ 3) for the TURB alone versus TURB+TURP groups, while the latest led to longer operative time (p<0.001). During a median follow-up of 44 months, there were more recurrences in the TURB-alone (47%) compared to the TURB+TURP group (28%; p<0.001). Interestingly, there were more recurrences at the bladder neck/prostatic fossa in the TURB-alone group (55% vs. 3%; p<0.001). TURB+TURP procedures were associated with improved RFS (HR 0.39, 95% CI 0.29-0.53, p<0.001), but not PFS (HR 1.63, 95% CI 0.90-2.98, p=0.11). Within the PSM cohort of 254 patients, the simultaneous TURB+TURP was still associated with improved RFS (HR 0.33, 95% CI 0.22-0.49, p<0.001). This was also true in the subgroup of 380 patients with recurrence risk factors (HR 0.41, 95% CI 0.28-0.62, p<0.001). CONCLUSION In our contemporary cohort, simultaneous TURB and TURP seems to be oncologically safe option that may, even, improve RFS by potentially preventing disease recurrence at the bladder neck and in the prostatic fossa.

Abstract
BACKGROUND Quadriceps tendon rupture (QTR) is a rare clinical condition often caused by indirect injury in healthy people. In addition, spontaneous and bilateral ruptures can occur in patients with predisposing factors, such as endocrine or rheumatic disease. Currently, several QTR repair techniques have been proposed; however, no consensus exists about the best repair technique. CASE PRESENTATIONS A 55-year-old man with renal failure secondary to glomerulonephritis suffered from spontaneous bilateral quadriceps tendon ruptures. Based on a knotless suture anchor and internal brace, a novel double-row suture-bridge configuration surgical approach was used to treat the patient. At 11-month follow-up, the patient maintained excellent function, with a Lysholm score of 91 for both knees. CONCLUSIONS This technique may be an effective method for repairing ruptured quadriceps tendons.

Abstract
BACKGROUND Published comparisons between bilateral and unilateral total knee arthroplasties (TKAs) remain biased, as most patients undergoing bilateral TKA are prescreened and healthier than average patients having unilateral procedures. Our objectives were to compare postoperative complications and resource utilization of patients having simultaneous bilateral TKAs with similar patients having unilateral procedures. METHODS The Nationwide Inpatient Sample (NIS) database was used to identify patients undergoing primary elective TKA from 2002 to 2011. A total of 4,445,263 patients were identified. Of these, 190,783 (4%) were having same-day bilateral procedures. Patients with staged bilateral TKA during the same hospitalization were excluded. Complications and costs were compared to a matched cohort of patients having unilateral procedures. This cohort was matched based on age, gender, and 30 comorbid-defined elements in the NIS. RESULTS A total of 172,366 (90%) simultaneous bilateral procedures were matched 1:1 to patients with unilateral procedures for the adjusted analysis. Patients with bilateral procedures were at an increased risk for many complications including postoperative anemia (OR: 2.3; 95% CI: 2.2-2.3, P < .001), cardiac (OR: 2.1; 95% CI: 2.0-2.3, P < .001), and inhospital mortality (OR: 3.3; 95% CI: 2.6-4.3). These patients also incurred in higher hospital costs ($19,343 vs $12,852, P < .001) and were discharged more commonly to a rehabilitation facility (70% vs 32%, P < .001). CONCLUSION Patients undergoing simultaneous bilateral TKA are at an increased risk of developing important postoperative complications and mortality compared with unilateral cases. These data highlight the importance of patient selection and optimization for bilateral TKA and potential cost savings.

Abstract
BACKGROUND This study aimed to evaluate the effect of perioperative dexamethasone on acute phase response (APR) after simultaneous bilateral total hip arthroplasty (SimBTHA). METHODS A retrospective case-control study was performed on 177 SimBTHA procedures. The patients were divided into 2 cohorts: patients receiving perioperative dexamethasone and patients in whom no dexamethasone was administered. We observed the effects of perioperative dexamethasone on the APR following SimBTHA by trending C-reactive protein and interleukin-6. Besides, the incidence of postoperative nausea and vomiting (PONV), postoperative visual analog scale (VAS) score, use of antiemetic and analgesic rescue, and complications were also compared. RESULTS Compared to the no dexamethasone group, patients receiving dexamethasone yielded a significantly decreased C-reactive protein on postoperative days 1, 2 and 3. Such differences of interleukin-6 were also detected. In addition, the incidence of PONV, postoperative VAS score, and use of antiemetic and analgesic rescue were significantly decreased without increasing the risk of early surgical wound infection and gastrointestinal hemorrhage in patients receiving dexamethasone. CONCLUSION The anti-inflammatory effects of dexamethasone can attenuate the APR after SimBTHA as well as decrease the PONV, postoperative VAS score, and use of antiemetic and analgesic rescue.

Abstract
In this paper, the classical least-squares (CLS) method with molecular absorption spectrophotometric measurement was used to determine simultaneously paracetamol (PAR), ibuprofen (IBU), and caffeine (CAF) in tablets. The absorbance spectra of the standard solutions and samples were measured over a wavelength from 220 to 300 nm with a 0.5 nm step. The concentration of PAR, IBU, and CAF in the sample solutions was calculated by using Visual Basic for Applications (VBA) and a program called CLS-Excel written in Microsoft Excel 2016. The method and the CLS-Excel program were tested on mixed standard laboratory samples with different PAR, IBU, and CAF concentration ratios, and they showed only small errors and a satisfying repeatability. An analytical procedure for tablets containing PAR, IBU, and CAF was developed. The reliability of the procedure was proved via the recovery and repeatability of the analysis results with an actual tablet sample and by comparing the mean contents of active substances in the tablets obtained from the analytical procedure with the HPLC method. The procedure is simple with a reduced cost compared with the HPLC standard method.

Abstract
BACKGROUND It is currently unknown if simultaneous bilateral total knee arthroplasty (si-BTKA) can also be safely performed in the outpatient setting. The primary aim of this study was to compare 30-day postoperative complication rates between outpatient and inpatient si-BTKA. METHODS Adults undergoing simultaneous bilateral total knee arthroplasty (si-BTKA) from 2015-2019 were queried using the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. Our primary analysis compared the rates of complications between outpatient si-BTKA and inpatient si-BTKA using bivariate comparisons and multivariable logistic regression of outpatient and inpatient cases controlling for differences in baseline demographics and comorbidities. RESULTS From 2015 to 2019, the utilization of outpatient si-BTKA increased from 0.6% to 10.5%. Outpatient si-BTKA were found to have significantly lower odds of any complication (OR = 0.49), minor complication (OR = 0.50), and postoperative transfusion (OR = 0.66) compared to inpatient cases. Outpatient si-BTKA also had a significantly shorter operative time. CONCLUSION Compared to inpatient si-BTKA, patients who undergo outpatient si-BTKA do not demonstrate increased rates of any complication, severe complications, and minor complications within 30-days postoperatively. Further insight is needed on the effect of outpatient si-BTKA on long-term outcomes.

Abstract
BACKGROUND Alcohol and marijuana are commonly used by young adults, and use of both substances, particularly at the same time, is prevalent among this population. Understanding the prevalence, patterns, correlates, and consequences of simultaneous alcohol and marijuana (SAM) use is important to inform interventions. However, this literature is complicated by myriad terms used to describe SAM use, including use with overlapping effects and same-day co-use. OBJECTIVES This scoping review identifies and describes the peer-reviewed literature focused on SAM use by young adults and distinguishes simultaneous use from same-day co-use of alcohol and marijuana. This review also provides a narrative summary of the prevalence of SAM use, patterns of SAM and other substance use, psychosocial correlates, and consequences of SAM use. ELIGIBILITY CRITERIA This review is limited to papers written in English and published in peer-reviewed journals between January 2000 and August 2021. It includes papers assessing simultaneous use or same-day co-use of alcohol and marijuana among young adults ages 18 to 30. Review papers, qualitative interviews, experimental lab studies, policy work, toxicology or medical reports, and papers focused on neurological outcomes are excluded. SOURCES OF EVIDENCE PubMed, PsycINFO, and Web of Science databases were searched. Databases were selected and the search strategy developed in consultation with an information specialist. CHARTING METHODS A data charting form was utilized to specify which information would be extracted from included papers. Eight categories of data were extracted: (1) research questions and hypotheses; (2) sample characteristics; (3) study procedures; (4) definition of SAM use; (5) prevalence of SAM use; (6) patterns of SAM and other substance use; (7) psychosocial correlates of SAM use; and (8) consequences of SAM use. RESULTS A total of 1,282 papers were identified through initial search terms. Through double-blind title/abstract screening and full-text review, the review was narrowed to 74 papers that met review inclusion criteria. Review of these papers demonstrated that SAM use was prevalent among young adults, particularly among those who reported heavier quantities and more frequent use of alcohol and marijuana. Enhancement-related motives for use were consistently positively associated with SAM use. SAM use was associated with greater perceived positive and negative consequences of alcohol and/or marijuana use. Inconsistencies in prevalence, patterns, correlates, and consequences were found between studies, which may be due to large variations in measurement of SAM use, populations studied, methodological design (e.g., cross-sectional vs. intensive longitudinal), and the covariates included in models. CONCLUSIONS The literature on simultaneous use and same-day co-use of alcohol and marijuana has expanded rapidly. Of the 74 included papers (61 on SAM use; 13 on same-day co-use), 60 papers (47 on SAM use; 13 on same-day co-use) were published within the last 5 years. Future research focusing on the ways in which SAM use confers acute risk, above and beyond the risks associated with separate consumption of alcohol and marijuana, is needed for understanding potential targets for intervention.

Abstract
Bisphosphonates are generally used to treat osteoporosis and decrease the risk of femoral neck and vertebral fractures in patients with osteoporosis. Recently, it has been suggested that long-term bisphosphonate use can lead to decreased bone remodeling and an increased risk of atypical fractures. Atypical fractures often occur in the femur. The purpose of the present report is to describe a rare case of simultaneous, bilateral, atypical femoral fractures. An 80-year-old female was walking when she sustained bilateral femoral fractures that were diagnosed as atypical. The patient had received bisphosphonate treatment over the prior nine years.

Abstract
BACKGROUND Simultaneous bilateral total knee arthroplasty (sim-BTKA) is reported to be safe in a select group of patients. Patients with symptomatic bilateral knee arthritis who are not candidates for sim-BTKA require staged surgery (stag-BTKA). This study aimed to compare the safety and complications associated with sim-BTKA with stag-BTKA performed at 2 time intervals. METHODS This retrospective study of prospectively collected data includes bilateral TKA cases performed between 2001 and 2019. A cohort of sim-BTKA (n = 2728) was compared to a cohort of stag-BTKA (n = 1658). The staged group was subdivided according to the interval between surgeries: ≤90 days (early) and ≥91 days (later). Multivariate logistic regression analyses were used to adjust for confounding variables. RESULTS In-hospital complication rates were lower in both arms of the stag-BTKA groups vs the sim-BTKA. The sim-BTKA group had higher odds ratio of anemia, electrolyte disturbances, pulmonary embolism, and respiratory, urinary, gastrointestinal, and neurological complications. Lower rates of all-cause revision were found in stag-BTKA vs sim-BTKA groups. There was a trend toward revision due to deep infection when increasing the interim before the second stag-BTKA procedure. No differences in complication rates after the second surgery were detected between the early and later stag-BTKA. CONCLUSION This study demonstrates that sim-BTKA is associated with more complications and revisions when compared to stag-BTKA. Performing the second-stage TKA at 90 days or less after the first TKA is not associated with increased risk of complications. Performing sim-BTKA, simply for convenience, is not warranted and should be reserved for a select group of patient matching specific criteria.

Abstract
BACKGROUND In acute pancreatitis (AP), serum amylase, lipase and imaging help establish a diagnosis with recognised lipase superiority. Recent literature has debated serum amylase testing and proposed its elimination, but little is known about the diagnostic role of simultaneously measured serum amylase levels in patients with non-diagnostic lipase. This study examined the contribution of pancreatic enzymes and imaging and the role of simultaneously measured serum amylase in children with non-diagnostic serum lipase. METHODS Retrospective medical records review of children aged <18 years with a verified discharge diagnosis of first-attack AP between January 01, 1994, and December 31, 2016. RESULTS First-attack AP was confirmed in 127 children (median age, 12.5 years). The sensitivity was 90.4%, 54.3%, 42.2% and 36.4% for lipase, amylase, contrast-enhanced computed tomography and ultrasonography (US), respectively. Combination US and lipase identified 96.6% of AP cases. Simultaneous amylase and lipase measurements in 125 children showed that either was ≥3× the upper limit of normal (ULN) in 95.2%, while both were <3× the ULN in 4.8% of cases. Nondiagnostic lipase was seen in 12 (9.6%) children, and diagnosis was based on amylase level ≥3× the ULN in six children and imaging in the other six. CONCLUSIONS Serum amylase, serum lipase and imaging should continue for the conclusive diagnosis of AP in children. Simultaneous serum amylase measurement helped diagnose AP with non-diagnostic lipase.

Abstract
Background: Hybrid treatments (HT) aim to reduce conventional open surgery invasiveness and address multilevel peripheral arterial disease (PAD). Herein, the simultaneous HT treatment in patients with chronic limb-threatening ischemia (CLTI) is reported. Methods: Retrospective analysis, for the period from May 2012 to April 2018, of patients presenting multilevel PAD with CLTI addressed with simultaneous HT. The outcomes of these interventions were measured the following metrics: early technical successes (within 30 days following treatment) and late technical successes (30 days or more following treatment) and included mortality, morbidity symptoms recurrence, and amputation. Survival and patencies were estimated. The median follow-up was 43.77 months. Results: In the 45 included patients, the HT consisted of femoral bifurcation patch angioplasty followed by an endovascular treatment in 38 patients (84.4%) and endovascular treatment followed by a surgical bypass in 7 patients (15.6%). Technical success was 100% without perioperative mortality. Eight (17.8%) patients presented early complications without major amputations. During the follow-up, seven (15.6%) deaths occurred and six patients (13.3%) experienced symptoms recurrence, with five of those patients requiring major amputation. An estimated survival time of 5 years, primary patency, and secondary patency was 84.4%, 79.2%, and 83.3% respectively. Conclusions: Hybrid treatments are effective in addressing patients presenting with multilevel PAD and CLTI. The common femoral artery involvement influences strategy selection. Larger studies with longer-term outcomes are required to validate the hybrid approach, indications, and results.

Abstract
Simultaneous bilateral patellar tendon rupture is an infrequent and debilitating injury. Although tendon rupture is associated with multiple systemic diseases, there is limited literature regarding its association with osteogenesis imperfecta and successful treatment techniques. We report a case of a 56-year-old man with a history of osteogenesis imperfecta type I who experienced bilateral patellar tendon rupture following a fall from standing height in the absence of other risk factors. Both injuries were effectively treated with primary open repair utilizing Krackow suture technique and transosseous tunnel fixation bilaterally. The patient demonstrated full functional recovery at 14-month follow-up. Osteogenesis imperfecta is a risk factor for the development of bilateral patellar tendon rupture. Open bilateral transosseous suture repair has proven to be successful despite defects in type 1 collagen and underlying tendon weakness.

Abstract
BACKGROUND Bilateral unicompartmental knee arthroplasty (UKA) can be divided into one or two stages clinically. Compared with staged bilateral UKA, whether simultaneous bilateral UKA has better clinical efficacy remains to be verified. METHODS PubMed, EBSCO, and Web of Science were searched by us for meta-analysis. Studies were considered eligible for inclusion if they included simultaneous and staged UKA. We excluded studies unrelated to the research question, studies in non-selected languages, and studies where the full-text was not available. The data were extracted by two independent investigators, and disagreements were resolved through discussions with a third party. If important data or information about the content of the paper were not available, authors were contacted. Publication bias in studies has been assessed. Meta-analysis was done using Review Manager 5.3. RESULTS The systematic review and meta-analysis identified 3370 trials, of which 8 studies (963 patients) compared simultaneous with staged bilateral UKA. The meta-analysis showed that the clinical outcomes of simultaneous bilateral UKA goes down in operating time (weighted mean difference [WMD] = -19.34, 95% confidence interval [CI] -22.44 to -16.25, P < .00001), postoperative hemoglobin (Std. mean difference [SMD] = -0.46, 95% CI -0.71 to -0.20, P = .0004), length of stay (LOS) (WMD = -4.73, 95% CI -6.39 to -3.06, P < .00001), hospital cost (SMD = -5.42, 95% CI -6.54 to -4.30, P < .00001). There were no significant difference in blood transfusion, venous thrombosis, infection, cardiac complications, pulmonary complications, Oxford Knee Score (OKS) between simultaneous and staged bilateral UKA. CONCLUSION Simultaneous bilateral UKA can effectively reduce the operating time, LOS, and hospital cost without increasing postoperative complications compared to stage bilateral UKA.

Abstract
PURPOSE Bilateral total knee arthroplasty (TKA) can be performed in patients with bilateral knee arthritis. Outside of nationwide database studies, which have limitations, few studies have compared outcomes for same-day versus staged TKA. We sought to compare patient outcomes at a single tertiary referral center. METHODS The institutional database was queried from March 2014 to December 2017 for primary TKA. Patients undergoing bilateral procedures were stratified by same-day versus staged; length of stay (LOS), disposition, 90-day emergency department (ED) visits, and 90-day readmissions were examined through univariable and multivariable analyses. RESULTS A total of 676 patients were evaluated (113 same-day and 563 staged bilateral TKA patients) with mean age 66.0 (8.5) at first surgery and 292.1 (241.6) days between staged procedures. Same-day bilateral TKA patients were younger (p < 0.001), had lower body mass index (BMI) (p = 0.010), and had lower American Society of Anesthesiologists (ASA) scores (p = 0.030). They were more likely to have a prolonged LOS (p < 0.001) and be discharged to skilled nursing facility or rehab facility (p < 0.001). Total LOS for separate hospitalizations in staged procedures was greater than LOS for same-day bilateral TKAs (p < 0.001). There was no difference in 90-day ED visits (p = 0.623) or readmission (p = 0.286). In a multivariable model controlling for age, BMI, and ASA score, same-day bilateral TKA was not significantly associated with ED visits or readmissions. CONCLUSIONS Patients undergoing same-day bilateral TKAs were more likely to be discharged to post-acute care facilities, however they did not have increased 90-day readmissions.

Abstract
BACKGROUND The purpose of this study is to evaluate early postoperative surgical and medical complications in patients undergoing staged bilateral total knee arthroplasty (TKA) and determine if the interval to the second stage influences the risk of complications. METHODS A retrospective review was performed from 2016 through 2018 of all staged bilateral primary TKA procedures, yielding a cohort of 1005 patients (2010 TKAs). Four groups were created based on the timing of the second stage: 3 to 6 weeks, 7 to 12 weeks, 13 to 24 weeks, and >24 weeks. Clinical data compared between groups included demographics, knee range of motion, University of California, Los Angeles (UCLA) activity score, Knee Society pain score, Knee Society clinical score, and Knee Society functional score. Postoperative complications within 90 days were evaluated, with complications after the second knee being the primary outcome. RESULTS The mean follow-up after second stage was 10.7 months (range, 3 to 37 months). No significant differences were found between groups in the range of motion, Knee Society pain, Knee Society clinical score, Knee Society functional score, or University of California Los Angeles activity score in either the first or second knee. After the first knee surgery, medical complications were highest in the >24-week group. After the second knee, there were no significant difference in manipulation (P = .9), wound complications (P = .7), venous thromboembolism (P = .8), or other medical complications (P = 1) based on the interval duration. CONCLUSION The interval between staged TKA did not affect early medical or surgical complications after the second stage. Early clinical and function results were not different based on timing of the second surgery.

Abstract
INTRODUCTION Bilateral renal tumors accounts for approximately 3% of renal tumors. However, surgical treatment methods for bilateral renal tumors have not yet been established. It is imperative to balance the need for curative surgery with the goal of maximal functional preservation in patients with bilateral synchronous renal tumors. Therefore, partial nephrectomy may be the optimal surgical treatment for bilateral synchronous renal tumors. METHODS We conducted a retrospective, observational study to analyze the clinical outcome of simultaneous robotic-assisted partial nephrectomy (RAPN) for bilateral renal tumors at our institution between 2016 and 2019. A total of eight patients were enrolled and the number of renal masses in the 16 kidneys was 18. RESULTS There was no positive surgical margin after RAPN in our case series and no local recurrence or metastasis during the follow-up period. The only complication of simultaneous RAPN in the present case series was that one patient experienced acute kidney injury after operation without need for dialysis therapy. CONCLUSION Our study suggests that simultaneous RAPN for bilateral renal tumors might be feasible both for the preservation of renal function and for oncological outcome such as negative surgical margin.

Abstract
OBJECTIVE Estimation of finger kinematics is an important function of an intuitive human-machine interface, such as gesture recognition. Here, we propose a novel deep learning method, named Long Exposure Convolutional Memory Network (LE-ConvMN), and use it to proportionally estimate finger joint angles through surface electromyographic (sEMG) signals. APPROACH We use a convolution structure to replace the neuron structure of traditional Long Short-Term Memory (LSTM) networks, and use the long exposure data structure which retains the spatial and temporal information of the electrodes as input. The Ninapro database, which contains continuous finger gestures and corresponding sEMG signals was used to verify the efficiency of the proposed deep learning method. The proposed method was compared with LSTM and Sparse Pseudo-input Gaussian Process (SPGP) on this database to predict the 10 main joint angles on the hand based on sEMG. The correlation coefficient (CC) was evaluated using the three methods on eight healthy subjects, and all the methods adopted the root mean square (RMS) features. MAIN RESULTS The experimental results showed that the average CC, RMSE, NRMSE of the proposed LE-ConvMN method (0.82±0.03,11.54±1.89,0.12±0.013) was significantly higher than SPGP (0.65±0.05, p<0.001; 15.51±2.82, p<0.001; 0.16±0.01, p<0.001) and LSTM (0.64±0.06, p<0.001; 14.77±3.21, p<0.001; 0.15±0.02, p=<0.001). Furthermore, the proposed real-time-estimation method has a computation cost of only approximately 82 ms to output one state of ten joints (average value of 10 tests on TitanV GPU). SIGNIFICANCE The proposed LE-ConvMN method could efficiently estimate the continuous movement of fingers with sEMG, and its performance is significantly superior to two established deep learning methods.

Abstract
In patients with specific dermatologic disorders who are affected by new corona virus, we know little about disease course (underlying disease and new onset infection), and the most proper management strategies include both issues that are what this systematic review targets. Databases of PubMed, Scopus, Google Scholar, Medscape, and Centre of Evidence-Based Dermatology, coronavirus dermatology resource of Nottingham University searched completely up to May 15, 2020, and initial 237 articles were selected to further review and finally 9 articles (including 12 patients) entered to this study. From 12 patients with chronic underlying dermatologic disease treated with systemic therapies, only 1 patient required Intensive Care Unit admission, the others have been treated for mild-moderate symptoms with conventional therapies. The biologic or immunosuppressive/immunomodulator agents have been ceased during the course of disease. The course of coronovirus diseases 2019 (COVID-19) and its management was as similar as normal populations. Their underlying dermatologic disease were exacerbating from mild to moderate. Their treatment has been continued as before, after the symptoms improved. Exacerbation of patients underlying dermatologic disease was mild to moderate. Discontinuing the treatment in the acute period of COVID and the restart after recovery may prevent severe recurrence and disturbing cytokine storms in these patients.

Abstract
Background The niche surgery of same-day bilateral total knee arthroplasty (sd-BTKA) continues to create debate amongst specialists in arthroplasty. To date, there is a significant lack of literature on obese patients undergoing sd-BTKA, and no study has evaluated outcomes of this procedure when compared to non-obese patients. Therefore, this study will perform a retrospective analysis to compare (I) incidence, (II) demographics, and (III) complications of sd-BTKA in non-obese, obese, and morbidly obese patients in the United States from 2009 to 2016. Methods The National Inpatient Sample (NIS) database was queried for all individuals that underwent sd-BTKA from 2009 to 2016. This returned 184,844 non-obese patients, 39,901 obese patients, and 20,394 morbidly obese patients. Analyzed variables included mean age, mean length of stay (LOS), race, payer, age-adjusted Charlson Comorbidity Index score, discharge disposition, hospital charges, hospital costs, and complications. Chi-square analyses and analyses of variance were utilized to assess categorical and continuous variables, respectively. Results Non-obese patients most commonly underwent sd-BTKA over the course of the study. As weight status increased, mean age decreased and the proportion of females, LOS, hospital charges and costs, and proportion of discharges to skilled nursing facilities increased. Regression analysis demonstrated obese and morbidly obese cohorts were at an overall increased odds for experiencing complications. Specifically, obese patients were at increased risk for pulmonary emboli, periprosthetic joint infections, and respiratory failures, while morbidly obese patients are at increased risk for pulmonary emboli, respiratory failures, and urinary tract infections. Conclusions Surgeons should thoroughly evaluate the risks and benefits of performing sd-BTKA on obese and morbidly obese patients, as both confer higher overall complication rates and increased length of stay. More research is necessary to characterize the cost analysis of this procedure, as health care models continue to transition to more cost-effective procedures.

Abstract
It is known that children and older adults produce more false alarms in target absent line-ups and that weaker facial encoding increases choosing bias. However, there has been no investigation of how age or facial encoding strength impacts line-up position selections in either sequential or simultaneous line-ups. In the present study, we presented participants with four live targets (one by one) while manipulating sequential and simultaneous line-ups between participants and target present and target absent line-ups within participants. In order to investigate facial encoding strength, we presented the targets at distances between 5 and 110 m. Our main hypotheses were that children due to deficits with inhibition would be more biased toward indiscriminate selections in the first position of sequential line-ups compared with subsequent line-up positions and that first position selections would increase for all age groups as facial encoding became weaker. In simultaneous line-ups, we expected to find a top row bias. In our sample (N = 1,588 participants; 6–77 years), we found that younger children (6–11 years) and the oldest adults (60–77 years) showed a first position bias in sequential line-ups, and as facial encoding became weaker, all age groups (6–11, 12–17, 18–44, 45–59, and 60–77 years) showed an increased tendency to make first position selections. We also found a weak top row preference in simultaneous line-ups, which was moderated by age and increased distance. The main finding is that the results suggest that younger children and the oldest adults had a tendency toward a first position selection bias in sequential line-ups. Based on the combined results, we recommend caution when using sequential line-ups with younger children or older adults.

Abstract
BACKGROUND Perioperative hospital adverse events represent a significant outcome that is often overlooked. Even "minor events" such as fever or tachycardia may lead to significant costs due to workup tests, interconsultations, and/or increased length of stay (LOS). The optimal timing of bilateral direct anterior approach total hip arthroplasty (DAA-THA) remains unsettled. Consequently, we wanted to compare hospital LOS, discharge disposition, hospital adverse events (major and minor), and transfusion rates between simultaneous and staged bilateral DAA-THA. METHODS A retrospective chart review was conducted on a consecutive series of 347 primary bilateral DAA-THAs (204 patients) performed by 2 surgeons in a single institution (2010-2016). The hips finally included were categorized as simultaneous (Sim-n = 61), staged 1 (Stg1-n = 143), or staged 2 (Stg2-n = 143). We also compared simultaneous with staged surgeries performed ≤1 and >1 year apart. Baseline demographics, LOS, discharge disposition, hospital adverse events, and transfusions were assessed. RESULTS The simultaneous group had significantly younger patients and a higher proportion of males when compared with the staged groups and showed significant longer LOS [2.61 (Sim) vs 2.06 (Stg1) vs 1.63 (Stg2) days, P < .001], lower proportion of home discharge [77% (Sim) vs 91.6% (Stg1) vs 96.5% (Stg2), P < .001], as well as higher (overall) rate of adverse events [31.1% (Sim) vs 28.7% (Stg1) vs 14.0% (Stg2), P = .003] and transfusions [45.9% (Sim) vs 6.3% (Stg1) vs 7.0% (Stg2), P < .001]. However, most transfusions were autologous [37.7% (Sim) vs 3.5% (Stg1) vs 0% (Stg2), P < .001]. CONCLUSION Our data show that bilateral DAA-THAs performed in a staged fashion, rather than simultaneously, have a shorter hospital LOS and decreased rates of adverse events and overall transfusions. Notwithstanding, simultaneous surgery should still be considered an option in selected patients. LEVEL OF EVIDENCE Level III.
