Background Analyses of blood biomarkers involved in the host response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral infection can reveal distinct biological pathways and inform development and testing of therapeutics for COVID-19. Our objective was to evaluate host endothelial, epithelial and inflammatory biomarkers in COVID-19. Methods We prospectively enrolled 171 ICU patients, including 78 (46%) patients positive and 93 (54%) negative for SARS-CoV-2 infection from April to September, 2020. We compared 22 plasma biomarkers in blood collected within 24 h and 3 days after ICU admission. Results In critically ill COVID-19 and non-COVID-19 patients, the most common ICU admission diagnoses were respiratory failure or pneumonia, followed by sepsis and other diagnoses. Similar proportions of patients in both groups received invasive mechanical ventilation at the time of study enrollment. COVID-19 and non-COVID-19 patients had similar rates of acute respiratory distress syndrome, severe acute kidney injury, and in-hospital mortality. While concentrations of interleukin 6 and 8 were not different between groups, markers of epithelial cell injury (soluble receptor for advanced glycation end products, sRAGE) and acute phase proteins (serum amyloid A, SAA) were significantly higher in COVID-19 compared to non-COVID-19, adjusting for demographics and APACHE III scores. In contrast, angiopoietin 2:1 (Ang-2:1 ratio) and soluble tumor necrosis factor receptor 1 (sTNFR-1), markers of endothelial dysfunction and inflammation, were significantly lower in COVID-19 (p Conclusions These studies demonstrate that, unlike other well-studied causes of critical illness, endothelial dysfunction may not be characteristic of severe COVID-19 early after ICU admission. Pathways resulting in elaboration of acute phase proteins and inducing epithelial cell injury may be promising targets for therapeutics in COVID-19.

Critically ill patients manifest many of the same immune features seen in coronavirus disease 2019 (COVID-19), including both “cytokine storm” and “immune suppression.” However, direct comparisons of molecular and cellular profiles between contemporaneously enrolled critically ill patients with and without severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) are limited. We sought to identify immune signatures specifically enriched in critically ill patients with COVID-19 compared with patients without COVID-19. We enrolled a multisite prospective cohort of patients admitted under suspicion for COVID-19, who were then determined to be SARS-CoV-2-positive ( n = 204) or -negative ( n = 122). SARS-CoV-2-positive patients had higher plasma levels of CXCL10, sPD-L1, IFN-γ, CCL26, C-reactive protein (CRP), and TNF-α relative to SARS-CoV-2-negative patients adjusting for demographics and severity of illness (Bonferroni P value < 0.05). In contrast, the levels of IL-6, IL-8, IL-10, and IL-17A were not significantly different between the two groups. In SARS-CoV-2-positive patients, higher plasma levels of sPD-L1 and TNF-α were associated with fewer ventilator-free days (VFDs) and higher mortality rates (Bonferroni P value < 0.05). Lymphocyte chemoattractants such as CCL17 were associated with more severe respiratory failure in SARS-CoV-2-positive patients, but less severe respiratory failure in SARS-CoV-2-negative patients ( P value for interaction < 0.01). Circulating T cells and monocytes from SARS-CoV-2-positive subjects were hyporesponsive to in vitro stimulation compared with SARS-CoV-2-negative subjects. Critically ill SARS-CoV-2-positive patients exhibit an immune signature of high interferon-induced lymphocyte chemoattractants (e.g., CXCL10 and CCL17) and immune cell hyporesponsiveness when directly compared with SARS-CoV-2-negative patients. This suggests a specific role for T-cell migration coupled with an immune-checkpoint regulatory response in COVID-19-related critical illness.

Isolated hematotrachelos is an ex- tremely rare condition. More commonly it is associated with hematometra and/or hematocolpos. It may devel- op secondary to congenital anomalies of the reproductive tract or may be an acquired condition following cervical surgery or manipulation. No case has been reported fol- lowing abdominal myomec- tomy.A 40-year-old, nul- ligravid woman was diag- nosed with isolated hemato- trachelos when she presented with severe abdominal pain following ovulation induction with clomiphene citrate. After the diagnosis was obtained, she recounted 2 similar presentations occurring months earlier. Both episodes had been attributed to gastroenteritis, but each had re- solved with "explosive" onset of menses. All 3 episodes plus 1 later recurrence happened within a 36-month period following an abdominal myomectomy.Acquired hematotrachelos is a rare condition, and the diagnosis is often missed. To our knowledge, this is the first reported case of isolated, recurrent hematotrachelos following the use of a uterine manipulator cannula in association with an abdominal myomectomy.

Six women with pseudocyesis were studied by 15-min blood sampling for 12 to 24 h to determine their gonadotropin and PRL secretory profiles aiming to clarify the endocrine alterations in this form of hypothalamic amenorrhea. Clinical and biochemical evidence of hyperandrogenism was found in 4 patients. Persistent hyperprolactinemia was present only in one patient. Significant circadian and ultradian periodicities were identified by time series analysis in the 12-24 h profiles of FSH, LH and PRL secretion. Pulse analysis by the Van Cauter (UL-TRA.JN) method revealed a 24-h mean LH interpulse interval of 91±21 min with a mean LH amplitude of 5.4±0.8 IU/l. There was a significantly lower pulse frequency at night than during the daytime. The mean 24-h PRL interpulse interval and pulse amplitude were 134±22 min and 9.2±1.8 IU/l, respectively. Both FSH and LH mean levels were higher during the daytime than at night, while the reverse was true for PRL values. Decreased LH pulse frequeny and amplitude emerged as the most distinctive findings. Antecedent hypothalamic-pituitary aberrations due to other endocrinopathies and the timing of the hormonal assessment (e.g. recovery phase) may explain, at least in part, the reported heterogeneity of neuroendocrinologic findings in pseudocyesis.

Objective To evaluate the efficacy and cost-effectiveness of postoperative follow-up telephone calls among pediatric patients who underwent adenotonsillectomy. Design Prospective study with a follow-up questionnaire administered by telephone. Setting Tertiary-care children's hospital. Patients One hundred thirty-four children between the ages of 4 and 18 years who underwent adenotonsillectomy between December 1997 and June 1998 and did not have associated cardiac, pulmonary, bleeding, or syndromic disorders were included in this pilot study. Intervention Parents of these patients were given the opportunity to participate in our study, and it was emphasized that, at any time during the child's care, if the parent desired a follow-up visit or if the child experienced any symptoms that caused concern, the parent should contact the clinic for a follow-up appointment. A telephone call was placed 3 to 4 weeks postoperatively by an otolaryngology nurse, and a questionnaire was filled out using the parents' responses. Main Outcome Measures The incidence rates of voice change, velopharyngeal insufficiency, bleeding, constipation, dehydration, and pain were measured. Parent satisfaction, patient safety, and cost-benefit were also evaluated. Results Less than 5% of patients reported temporary velopharyngeal insufficiency, while 2% of patients required operative intervention for bleeding episodes and 1% required hospitalization. Voice change, reported by approximately 70% of all patients, was the most common complaint, but it resolved in all instances. Pain was reported to be most severe on postoperative day 1. Ninety-six percent of parents requested no further follow-up visit. Conclusions Our pilot study revealed that a follow-up telephone call is a safe and cost-effective method of postoperative management for pediatric patients who have undergone adenotonsillectomy and that this method of follow-up is also desirable to parents.

Objective The aim of our study was to determine the prevalence of human immunodeficiency virus-1 (HIV-1) in an infertile population. Design The study design included a retrospective anonymous survey of clinical data and screening for HIV-1 antibody by enzyme-linked immunoabsorbent assay (ELISA) in stored sera. Samples that were ELISA-positive were further tested by Western blot assay. Frequency distributions were analyzed by Fisher's exact test. Setting University tertiary care center. Participants Based on availability of stored frozen sera, the total study population included 182 of 304 consecutively registered infertile couples. Results Seventy-five percent of the study population were found to have one or more risk factors for HIV infection. Of the 252 sera tested, 10 were repeatedly reactive by ELISA, and Western blot testing confirmed HIV-1 infection in one woman and two men. Conclusions This relatively high HIV-1 seroprevalence (male: 2.6%; female: 0.6%) in a low-middle class infertile population emphasizes the urgent need to implement on-site HIV-infection counseling aimed at preventing the spread of disease to the healthy partner and fetus and to discuss therapeutic and reproductive options.

Articulation therapy was administered to 240 children by 17 speech clinicians working in a suburban school system. Articulation testing was completed both before and after an eight and one-half months' treatment period. Group therapy was found to be as effective as individual therapy, regardless of the severity of speech defectiveness or grade levels of the children.
