Due to the COVID-19 pandemic, the Food and Drug Administration issued an Emergency Use Authorization to permit developers of certain serological tests to market their product prior to a comprehensive review. Nonetheless, the reliability of these assays is of great importance in order to be useful as a tool in estimating the relative proportions of different populations that have been exposed to SARS-CoV-2. We provide a sampling of 145 individuals from an ambulatory setting simultaneously tested with a qualitative point of care rapid finger prick Lateral Wave® IgM and IgG assay and a sample for the Mayo Clinic enzyme linked immunosorbent assay (ELISA) IgM/IgG antibody assay. Significant discrepancies did exist between the purported antibody responses as demonstrated by each assay.
To investigate the course of biomarkers on admission and follow-up in order to identify early predictors for poor outcome in COVID-19 patients.
In this study, 132 COVID-19 patients were classified as good outcome (n=62) and poor outcome (n=70) groups. Laboratory parameters were evaluated on admission and within 5-7 days after hospitalization.
Baseline levels of neutrophil-lymphocyte ratio, CRP, procalcitonin, ferritin, D-dimer and LDH were higher (
<0.01); lymphocyte count was lower in the poor outcome patients. During follow-up there was a larger decrease in lymphocyte count and more prominent increases in other biomarkers (
<0.001). In ROC analysis, the AUCs strongly indicated the poor outcome on days 5-7 of the hospitalization.
This study suggests that the follow-up measurements of the biomarkers better predict the poor outcome in COVID-19 pneumonia.

Calprotectin is a biomarker of gastrointestinal inflammation and disease activity. We aimed to evaluate the performance of a new fecal calprotectin (FC) test (CALiaGold®) in comparison with two other rapid FC immunoassays.
Fecal samples were analyzed with all three FC tests. YAP inhibitor Correlation between the FC tests was assessed. Agreement to discriminate FC-positive samples was also evaluated according to the manufacturers' cut-off values.
A correlation coefficient of over 0.800 was found in all comparisons. Lower deviation of linearity was observed between immunoturbidimetric assays. Agreement on FC-positive sample detection was reduced in comparisons with the immunochromatographic assay.
The CALiaGold® test showed good performance for FC assessment. Better correlation and agreement between immunoturbidimetric assays were confirmed.

In the interim, we have the opportunity to consider its clinicopathobiology in the context of the pharmacologic correlates available from the existing medical literature to prevent the COVID-19 infected patient from progressing into a fatal stage. This commentary serves as a forum for that end and suggests relatively non-toxic therapies that could be applied in a combinatorial fashion for consideration by the physicians and their patients with COVID-19 infection.The present study reported a rare case with thymic carcinoid as the first manifestation of multiple endocrine neoplasia type 1 (MEN1) syndrome, which presented with gene mutations of the MEN1 and glucokinase regulatory protein (GCKR). In this report, a 40-year-old male was diagnosed as MEN1 syndrome with thymic carcinoid, pancreatic cancer, hyperparathyroidism, and insulinoma with intrahepatic metastasis. Genetic testing showed the mutations of the MEN1 (c.378 G>A, p. Trp126*) in the patient, his children and two sisters, and GCKR (c.151C>T, p. Arg51*) gene in the patient and his children. The pathological examination showed that neuroendocrine tumor (NET) of the pancreas was characterized as 6 mitoses per 10 high-power fields (HPF), infiltration of adipose tissue, no intravascular tumor thrombus and nerve infiltration. In addition, NET of the liver was characterized as 4 mitoses per 10 HPF, no intravascular tumor thrombus and nerve infiltration. Immunohistochemical staining showed Ckpan (+), Syn (+), CgA (+), CD 56 (+), PGP 9.5 (+), and Ki67-positive cells (8-10%) in NET. Therefore, we suggested that genetic testing in family members of MEN1 patient, which may be helpful for early diagnosis.Baraitser-Winter Cerebro-fronto-facial syndrome (BWCFF, OMIM #243310, #614583) is caused by a heterozygous gain-of-function mutation of ACTB and ACTG1 that encodes actin. The syndrome is characterized by striking facial features, structural brain abnormalities, ocular coloboma, hearing loss, cardiac defects, intellectual disabilities, short stature, and developmental delay. We report a two-year-old girl who had distinctive facial features, including hypertelorism, arched eyebrows, bilateral ptosis, short broad nose with a flat nasal tip, long philtrum, retrognathia, low-set ears, and a thin upper lip. In addition, she also exhibited short stature, pectus excavatum, developmental delay, brain malformation, and hearing loss. Targeted gene panel sequencing identified a de novo heterozygous missense variant c.826G>A (p.Glu276Lys) in ACTB This is the first Korean case of BWCFF with a novel mutation in ACTB.Adenomatoid tumor is a rare tumor of mesothelial origin, usually arising in the epididymis. It is the most common paratesticular tumor of middle-aged men. A rare variant of adenomatoid tumor is leiomyoadenomatoid tumor which is characterized by prominent spindle cell myoblastic and myofibroblastic proliferation in the background of an adenomatoid tumor with tubular spaces lined by mesothelial cells. In some cases, the spindle cell component obscures the adenomatoid tumor component, complicating accurate diagnosis. Here, we report two cases of paratesticular leiomyoadenomatoid tumor in 28-year-old and 50-year-old patients. The tumors from both cases were centered in the epididymis and measured 1.0 cm and 3.0 cm, respectively. Both had similar morphology with myofibroblastic proliferation in one case and myoblastic (smooth muscle) proliferation in the other. Both cases followed a benign course without local recurrence or distant metastasis for 14 and 22 months postoperatively, respectively. We propose the use of the term "adenomyomatoid tumor" to describe a neoplasm exhibiting adenomatoid tumor admixed with either leiomyomatous or myofibroblastic proliferation.Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a rare primary and highly aggressive intestinal T-cell lymphoma derived from intraepithelial lymphocytes. MEITL is previously designated as type II enteropathy-associated T cell lymphoma (EATL). Unlike to classic form of EATL, MEITL is not associated with celiac disease. The diagnosis of MEITL is very challenging and the clinical outcome of patients with MEITL is very poor. Herein we describe a series of four patients diagnosed with MEITL identified upon a 10-year institutional retrospective review. Histopathologic examination of these cases revealed monotonous population of medium sized cells infiltrating intestinal mucosa, positive for CD3, CD8 and CD56 in all four cases. Two patients had the combination chemotherapy; however, the average survival time was only 7.5 months for these two patients after diagnosis. The aim of the present case series is to highlight the pathology, diagnosis and clinical course of the patients with MEITL based on the current literature.

We aimed at investigating the expression level of vascular endothelial growth factor-A (VEGF-A) in patients with primary Sjögren's Syndrome (pSS) and evaluating the relationship between serum VEGF-A and the laboratory indicators that are associated with it in pSS.
The VEGF-A levels were measured by ELISA in a total of 88 participants, including 58 patients with pSS and 30 healthy people. The VEGF-A levels between two groups were analyzed.
The serum levels of VEGF-A in pSS and control groups were 175.50 (112.00,296.50) pg/mL and 181.50 (155.25,288.50) pg/mL, without statistically significant difference. The associations were found between serum levels of VEGF-A with C reactive protein (CRP) (r=0.265,
<0.05), white blood cells (WBC) (r=0.302, P<0.05), neutrophils (NEUT) (r=0.349,
<0.05), platelets(PLT) (r=0.276,
<0.05), complement 3 (C3) (r=0.477, P<0.05), complement 4 (C4) (r=0.387,
<0.05) and CA19-9 (r=0.392,
<0.05). Among these laboratory indicators, VEGF-A was correlated with platelets and complement 4 in patients with pSS.
In patients with pSS, the levels of VEGF-A were independently influenced by the levels of platelet and complement 4, which indicated the intermodulation between the growth factor and immune system in the autoimmune disease.

Major ABO incompatible hematopoietic progenitors from bone marrow (HPC(M)) donor collections that are destined for clinical transplantation are typically processed to deplete products of red blood cells (RBCs). The purpose of this study was to compare RBC depletion when using the Spectra Optia® relative to a 2-step method involving a COBE2991 instrument to obtain a buffy coat followed by a hydroxyethyl starch (HES) density gradient (COBE+HES) of the buffy coat.
Post-processing recoveries of products undergoing 4, 8, and 10 bone marrow processing (BMP) cycles (i.e. 1 cycle=1 volume of HPC(M)) with the Spectra Optia® were determined for volume, RBC content, viable total nucleated cells (vTNC), viable CD34+ cells (vCD34), viable CD3+ cells (vCD3) and colony-forming-cells (CFC). Subsequent RBC depletions with Spectra Optia® were then performed with 10 BMP cycles on additional HPC(M) collections and were compared against a retrospective analysis of historical COBE+HES post-processing data.
Ten BMP cycles of HPC(M) (n=6) products were identified as optimal with volume reductions of 81.
