The prepared aspirin-loaded hybrid nanofibers can be further transferred into an oral dosage form for potential application in countering COVID-19 in the future.The Coronavirus (COVID-19) pandemic sparked rapid widespread adoption of telemedicine throughout specialties, including orthopaedics.  learn more A succession of factors, starting with payers, followed by provider adoption, and reciprocated by patient approval, created newly accepted telehealth practices that have moved from trial to norm in a short time span. Orthopaedic surgeons believe telehealth will endure as a permanent change to their practice beyond the COVID-19 era, however, many permanent changes must take place by payers, providers, and patients to sustain telehealth into the future. The goal of this paper is to highlight the indelibility of telemedicine adoption in orthopaedic practices globally, characterize the chain of events that led to its large-scale adoption, and catalyze discussion around actionable next steps to sustain its benefits.
Orthopedic surgical procedures (OSPs) are known to generate bioaerosols, which could result in transmission of infectious diseases. Hence, this review was undertaken to analyse the available evidence on bioaerosols in OSPs, and their significance in COVID-19 transmission.

A systematic review was conducted by searching the PubMed, EMBASE, Scopus, Cochrane Library, medRxiv, bioRxiv and Lancet preprint databases for studies on bioaerosols in OSPs. Random-effects metanalysis was conducted to determine pooled estimates of key bioaerosol characteristics. Risk of bias was assessed by the RoB-SPEO tool; overall strength of evidence was assessed by the GRADE approach.

17 studies were included in the systematic review, and 6 in different sets of meta-analyses. The pooled estimate of particle density was 390.74μg/m
, Total Particle Count, 6.08×10
/m
, and Microbial Air Contamination, 8.08CFU/m
. Small sized particles (</=0.5 μm) were found to be 37 and 1604 times more frequent in the aerosol cloud in comparison to medium and large sized particles respectively. 4 studies reported that haemoglobin could be detected in aerosols, and one study showed that HIV could be transmitted by blood aerosolized by electric saw and burr. The risk of bias for all studies in the review was determined to be high, and the quality of evidence, low.

Whereas there is evidence to suggest that OSPs generate large amounts of bioaerosols, their potential to transmit infectious diseases like COVID-19 is questionable. High-quality research, as well as consensus minimum reporting guidelines for bioaerosol research in OSPs is the need of the hour.

Involvement of locoregional lymph nodes is the most significant prognostic factor for patients with penile cancer. In this study, we reviewed clinical data of all patients who underwent modified inguinal lymph node dissection as a means to diagnose micro-metastasis in inguinal lymph nodes, and analysed the outcomes. We retrospectively reviewed the hospital clinical charts of patients treated for carcinoma of the penis. Inguinal and distant metastases were assessed by physical examination, ultrasound imaging of the inguinal region, computed tomography of the abdomen and pelvis and a chest radiograph. Patients with clinically negative inguinal lymph nodes underwent modified lymph node dissection (mILND) both to diagnose and stage the disease. Complications occurring during a 30-day period after surgery were defined as early and thereafter as late complications. A total of 40 patients with a mean age of 52.27±13.10 (range 25-73) years underwent mILND. Wedge biopsy from the primary lesion had revealed intermediate-risk disease in 22 (55%) patients and high-risk disease in 18 (45%) patients. Histopathological examination of the primary penile lesion revealed a pT1 lesion in 32 patients and a pT2 lesion in the remaining 8 patients. Fourteen (35%) of the 40 patients showed micro-metastases in the inguinal lymph nodes on frozen sections. The mean follow-up in these patients was 56.6±18.09 months. There were no instances of local or systemic recurrences seen in 38 (95%) patients within 5 years. Superficial lymph node dissection and where facilities are available DSLNB remain the standard of care in the management of patients with clinically groin-negative (cN0) intermediate- and high-risk groups. Modified inguinal lymph node dissection would be a safe and appropriate alternative to this in all centres that do not have access to newer modalities like DSLNB, video-endoscopic (VEIL) or robotic-assisted techniques.Several transanal platforms were used to perform transanal total mesorectal excision (TaTME). They can be classified into rigid reusable platforms or flexible single-use platforms. The choice of transanal platform usually depends on the availability and the surgeon's discretion. To the best of our knowledge, this is the first study to compare the operative and oncologic outcome of flexible and rigid platforms during TaTME. This is a retrospective cohort study in which rectal cancer patients operated by TaTME in two tertiary centers from June 2013 to April 2019 were included. They were classified into two groups according to the platform used either the rigid platform group (n = 17) or the flexible platform (n = 14). Operative feasibility and short-term oncologic data were analyzed and reported. A total number of 31 patients were divided into either the rigid platform group (n = 17) versus the flexible platform one (n = 14). Shorter operating time, less blood loss, better TME specimens, and lymph node yield were reported in the flexible platform group. Flexible platforms were associated with better operative outcomes. Although there were no differences in circumferential and distal margins between the two groups, better TME specimens' quality and lymph node yield were reported in the flexible platform group. Future prospective trials are encouraged to provide better evidence.
