Through a projection map used to synchronize the signal, the distortion effect of the mobile phone is removed.<br /><br /> The experimental results show that the average correlation coefficient (ρ) between the recovery signal obtained by the proposed method and the reference signal is 0.9855±0.0108 for FHR and 0.9866 ± 0.1020 for UC, and the root mean square errors (RMSE) of FHR and UC processed by the proposed method are 1.0366 ± 0.4953 and 2.0355 ± 1.0246, and the mean absolute errors (MAE) of FHR and UC processed by the proposed method are 0.8735 ± 0.0684 and 1.4991 ± 0.2837, which are higher than those of the existing digitization methods. Compared with clinical signals, no significant difference is found in the feature of digitization CTG.<br /><br /> The proposed digitization method is a promising useful tool to realize the electronization of CTG signal.<br /><br />The proposed digitization method is a promising useful tool to realize the electronization of CTG signal.Soon after reports of a novel coronavirus capable of causing severe pneumonia surfaced in late 2019, expeditious global spread of the Severe Acute Respiratory Distress Syndrome Coronavirus 2 (SARS-CoV-2) forced the World Health Organization to declare an international state of emergency. Although best known for causing symptoms of upper respiratory tract infection in mild cases and fulminant pneumonia in severe disease, Coronavirus Disease 2019 (COVID-19) has also been associated with gastrointestinal, neurologic, cardiac, and hematologic presentations. Despite concerns over poor specificity and undue radiation exposure, chest imaging nonetheless remains central to the initial diagnosis and monitoring of COVID-19 progression, as well as to the evaluation of complications. Classic features on chest CT include ground-glass and reticular opacities with or without superimposed consolidations, frequently presenting in a bilateral, peripheral, and posterior distribution. More recently, studies conducted with MRI hantamination of scanner bays is a time-consuming process, and proper ventilation of scanner suites may additionally require up to an hour of downtime to allow for sufficient air exchange.

Especially for patients with concomitant malignancies and other states of immunocompromise, prompt recognition of infection and early initiation of supportive care is crucial to maximizing outcomes and improving survivability.<br /><br /> The coronavirus disease 2019 pandemic restricted movement of individuals and altered provision of health care, abruptly transforming health care-use behaviors. It serves as a natural experiment to explore changes in presentations for surgical diseases including acute appendicitis. The objective was to determine if the pandemic was associated with changes in incidence of acute appendicitis compared to a historical control and to determine if there were associated changes in disease severity.<br /><br /> The study is a retrospective, multicenter cohort study of adults (N= 956) presenting with appendicitis in nonpandemic versus pandemic time periods (December 1, 2019-March 10, 2020 versus March 11, 2020-May 16, 2020). Corresponding time periods in 2018 and 2019 composed the historical control. Primary outcome was mean biweekly counts of all appendicitis presentations, then stratified by complicated (n= 209) and uncomplicated (n= 747) disease. Trends in presentations were compared using difference-in-differences methodolses of uncomplicated appendicitis may resolve without progression to complicated disease.<br /><br />The pandemic was associated with decreased incidence of uncomplicated appendicitis without an accompanying increase in complicated disease. Changes in individual health care-use behaviors may underlie these differences, suggesting that some cases of uncomplicated appendicitis may resolve without progression to complicated disease.<br /><br /> Surgery is a common gateway to opioid-related morbidity. Ambulatory anorectal cases are common, with opioids widely prescribed, but there is limited data on their role in this crisis. We sought to determine prescribing trends, new persistent opioid use rates, and factors associated with new persistent opioid use after ambulatory anorectal procedures.<br /><br /> The Optum Clinformatics claims database was analyzed for opioid-naïve adults undergoing outpatient hemorrhoid, fissure, or fistula procedures from January 1, 2010, to June 30, 2017. The main outcome measure was the rate of new persistent opioid use after anorectal cases. Secondary outcomes were annual rates of perioperative opioid fills and the prescription size over time (oral morphine equivalents).<br /><br /> A total of 23,426 cases were evaluated 69.09% (n= 16,185) hemorrhoids, 24.29% (n= 5,690) fissures, and 6.45% (n= 1,512) fistulas. The annual rate of perioperative opioid fills decreased on average 1.2%/year, from 72% in 2010 to 66% in 2017 (P &lt; .001). Prescrn little change in the amount prescribed. This demonstrates a need to develop and disseminate best practices for anorectal surgery, focusing on eliminating unnecessary opioid prescribing.<br /><br />Over 2% of ambulatory anorectal procedures develop new persistent opioid use. Despite small annual reductions in opioid prescriptions, there has been little change in the amount prescribed. This demonstrates a need to develop and disseminate best practices for anorectal surgery, focusing on eliminating unnecessary opioid prescribing.Multi-fragment fractures are still a challenge current clinical practice relies on plates and screws. Treatment of fractures of the proximal humerus has the intra-operative risk of articular damage when inserting multiple screws. Distal-varus collapse of the head is a frequent complication in osteoporotic patients. The aim of this biomechanical study was to investigate if an Innovative-cement-technique (the screws are replaced by injection of cement) provides the same or better stability of the reconstructed head compared to the Standard-technique (locking screws). A four-fragment fracture was simulated in twelve pairs of humeri, with removal of part of the cancellous bone to simulate osteoporotic "eggshell" defect. One humerus of each pair was repaired either with a Standard-technique (locking plate, 2 cortical and 6 locking screws), or with the Innovative-cement-technique (injection of a partially-resorbable reinforced bone substitute consisting of PMMA additivated with 26% beta-TCP). Cement injection was performed both in the lab and under fluoroscopic monitoring.
