Coronavirus disease (COVID-19) rapidly spread worldwide in a few months and was declared as a worldwide pandemic by WHO in March 2020. Transient benign hyperphosphatasemia (THI) is a benign condition associated with marked elevation of alkaline phosphatase (ALP) without any other kidney, bone, and liver pathologies.

Herein, we report a previously healthy 16-month-old female patient who developed a secondary transient benign hyperphosphatasemia associated with SARS-CoV-2. Patient whole family's SARS-CoV-2 real-time reverse transcription-polymerase chain reaction (RT-PCR) results were positive. Since THI is a diagnosis of exclusion, other reasons that may cause ALP elevation should be ruled out. ALP activity decreased and turned to normal ranges within the following month. THI has been reported to be in association with various conditions. Its relationship with many viruses has been reported previously.

If ALP elevation is detected in patients with COVID 19 due to the increasing number of infections, THI should be considered if there is no other accompanying pathology.

These particles were shown to accelerate wound healing, through delivery of regenerative mediators, such as microRNAs. Herein we describe an optimized and upscalable process for the isolation of EV smaller than 200 nm (sEV), secreted by umbilical cord blood mononuclear cells (UCB-MNC) under ischemic conditions and propose quality control thresholds for the isolated vesicles, based on the thorough characterization of their protein, lipid and RNA content. Ultrafiltration and size exclusion chromatography (UF/SEC) optimized methodology proved superior to traditional ultracentrifugation (UC), regarding production time, standardization, scalability, and vesicle yield. Using UF/SEC, we were able to recover approximately 400 times more sEV per mL of media than with UC, and upscaling this process further increases EV yield by about 3-fold. UF/SEC-isolated sEV display many of the sEV/exosomes classical markers and are enriched in molecules with anti-inflammatory and regenerative capacity, such as hemopexin and miR-150. Accordingly, treatment with sEV promotes angiogenesis and extracellular matrix remodeling, in vitro. In vivo, UCB-MNC-sEV significantly accelerate skin regeneration in a mouse model of delayed wound healing. The proposed isolation protocol constitutes a significant improvement compared to UC, the gold-standard in the field. Isolated sEV maintain their regenerative properties, whereas downstream contaminants are minimized. The use of UF/SEC allows for the standardization and upscalability required for mass production of sEV to be used in a clinical setting.
Adrenocortical carcinoma (ACC) is often a contraindication to minimally invasive adrenalectomy (MIA). We used an administrative data set to analyze postoperative outcomes. We hypothesized that small tumors would have better short- and long-term outcomes, independent of the operative approach.

The National Cancer Database (2010-2016) identified patients with ACC who underwent adrenalectomy. Tumors were grouped<5 cm (n = 125), 5-10 cm (n = 431), and>10 cm (n = 443). The primary and secondary outcomes were margin positivity and overall survival, respectively.

Nine hundred and ninety-ninepatients were analyzed 37% MIA and 63% open adrenalectomy (OA). As the size increased, the rate of attempted MIA decreased. Larger tumors were associated with conversion to open. ALK inhibitor Althoughtumors with local invasion and those which required conversion to open were associated with an increased likelihood of a positive margin, tumor size was not. Although "complete" MIA (vs. OA) and tumor size were not associated with differences in survival, conversion (HR = 1.83, p = .02), positive margins (HR = 1.54, p = .01), and local invasion (HR = 1.84, p < .001) were associated with poor survival.

Positive margins are associated with poor survival in ACC. Tumors ≥ 5 cm were associated with an increased conversion rate and subsequent increase in margin positivity. MIA may be considered for select patients with small tumors but adequate oncologic resection is critical.

Inclusion body myositis (IBM) is a progressive inflammatory myopathy with dysphagia as a debilitating sequalae. Otolaryngologists are consulted for surgical candidacy when there are findings of cricopharyngeal dysfunction. We aim to compare transcervical cricopharyngeal myotomy (TCPM) versus endoscopic cricopharyngeal myotomy (ECPM) in the IBM population with particular focus on objective swallow study outcomes, complications, and recurrence rates.

A retrospective cohort study was performed on IBM patients who underwent TCPM or ECPM (1981-2020) in the Department of Otolaryngology at a tertiary academic center with a high volume IBM referral base. Videofluoroscopic swallow studies, Eating Assessment Tool (EAT-10), Reflux Symptom Index (RSI), and Functional Outcome Swallowing Scale (FOSS) were collected at preoperative and follow-up visits. Baseline patient characteristics, intraoperative data, and postoperative course were recorded.

Forty-one patients were identified (18 TCPM; 23 ECPM). There was no significant difference in the recurrence rates, complications, hospitalization length, operative time, or return to preoperative diet between approaches. For the 12 patients (11 ECPM; 1 TCPM) that had subjective swallow data, there was a statistically significant difference in the pre and postoperative scores for EAT-10, RSI, and FOSS (P < .05). There was a statistically significant improvement in the degree of narrowing between pre and postoperative imaging for both approaches (P < .05).

Both TCPM and ECPM are safe approaches for the management of dysphagia in patients with IBM with objective evidence of cricopharyngeal dysfunction. Cricopharyngeal myotomy is a durable technique that has demonstrated improved subjective and objective outcomes in this patient population.

In this study, we focus on mRNA, protein and viral miRNA expression profiles in C. auratus gibelio caudal fin (GiCF) cells infected with CyHV-2, using high-throughput sequence techniques and TMT-labelled analyses. The results revealed that 156 virus genes were differentially expressed during the infection. Among these differentially expressed genes, 7 viral genes were significantly up-regulated and 28 were significantly down-regulated at 96 hpi (hours post-infection) vs 48 hpi. Besides, a total of 78 viral proteins, including a large number of membrane proteins and capsid proteins associated with the viral assembly, were successfully detected by using proteome analysis. Furthermore, a total of 225,143,474 raw reads were generated from cDNA library of CyHV-2-infected GiCF cells using high-throughput sequencing technology. Following annotation and secondary structure prediction, 10 viral miRNAs were found as significantly modulated in CyHV-2-infected GiCF cells (2 down-regulated and 8 up-regulated). Finally, the CyHV-2 genes (orf19, orf23, orf118, orf121, orf127) targeted by the viral miRNA CyHV-2-KT-635 identified in this study, were predicted and validated by quantitative reverse transcription polymerase chain reaction (qRT-PCR), and the regulation of CyHV-2-KT-635 on orf121 protein expression was verified by western blotting assay. Taken together, this study provides a valuable basis for further research on the expression of virus genes during CyHV-2 replication and the molecular mechanisms by which miRNA may regulate CyHV-2 virus.
There has been a growing trend toward minimally invasive surgery (MIS) for colon cancer. Pathological analysis of a minimum of 12 lymph nodes (LNs) is a benchmark for adequate resection. Here, we present a comparison of surgical techniques in achieving a full oncologic resection.

Patients undergoing surgery for Stage I-III colon cancer (2010-2016) were identified from the National Cancer Database. Cases were stratified by surgical approach. Trends in approach were assessed, including whether the 12-LN benchmark was met. Uni- and multivariate regression was used to assess overall survival (OS).

A total of 290,776 colectomies were analyzed. MIS increased from 32.8% to 57.2% from 2010 to 2016 (p < .001). An overall median of 18 LNs were harvested and compliance with the 12-LN benchmark increased (84.6%-91.6%, p < .001); there were no difference between open and MIS. A subset analysis comparing hospital type revealed that regardless of approach, compliance was lower at community hospitals (p < .001). OS was better for patients treated at academic or National Cancer Institute centers, underwent MIS, and in those meeting the 12-LN benchmark (all p ≤ .002).

As MIS colon resections continue to increase, we demonstrate that there is no difference in the ability to achieve the 12-LN benchmark with open and MIS approaches.

In order to maintain the barrier function, the gut utilizes many defense mechanisms including proliferation, apoptosis, and apical junctional complexes. Disruption of any of these parameters due to injury or disease could negatively impact the intestinal barrier function and homeostasis resulting in increased intestine inflammation, permeability, bacterial dysbiosis, and tissue damage. MicroRNAs are small noncoding RNA sequences that are master regulators of normal cellular homeostasis. These regulatory molecules affect cellular signaling pathways and potentially serve as candidates for providing a mechanism of impaired gut barrier integrity following GI-related pathologic conditions, ethanol exposure, or trauma such as burn injury. MicroRNAs influence cellular apoptosis, proliferation, apical junction complex expression, inflammation, and the microbiome.
