Fibrotic posterior capsular opacification (PCO), one of the major complications of cataract surgery, occurs when lens epithelial cells (LCs) left behind post cataract surgery (PCS) undergo epithelial to mesenchymal transition, migrate into the optical axis and produce opaque scar tissue. LCs left behind PCS robustly produce fibronectin, although its roles in fibrotic PCO are not known. In order to determine the function of fibronectin in PCO pathogenesis, we created mice lacking the fibronectin gene (FN conditional knock out -FNcKO) from the lens. While animals from this line have normal lenses, upon lens fiber cell removal which models cataract surgery, FNcKO LCs exhibit a greatly attenuated fibrotic response from 3 days PCS onward as assessed by a reduction in surgery-induced cell proliferation, and fibrotic extracellular matrix (ECM) production and deposition. This is correlated with less upregulation of Transforming Growth Factor β (TGFβ) and integrin signaling in FNcKO LCs PCS concomitant with sustained Bone Morphogenetic Protein (BMP) signaling and elevation of the epithelial cell marker E cadherin. Although the initial fibrotic response of FNcKO LCs was qualitatively normal at 48 hours PCS as measured by the upregulation of fibrotic marker protein αSMA, RNA sequencing revealed that the fibrotic response was already quantitatively attenuated at this time, as measured by the upregulation of mRNAs encoding molecules that control, and are controlled by, TGFβ signaling, including many known markers of fibrosis. Most notably, gremlin-1, a known regulator of TGFβ superfamily signaling, was upregulated sharply in WT LCs PCS, while this response was attenuated in FNcKO LCs. As exogenous administration of either active TGFβ1 or gremlin-1 to FNcKO lens capsular bags rescued the attenuated fibrotic response of fibronectin null LCs PCS including the loss of SMAD2/3 phosphorylation, this suggests that fibronectin plays multifunctional roles in fibrotic PCO development. STUDY OBJECTIVE To assess hormone replacement therapy (HRT) prescription pattern in patients undergoing premature surgical menopause based on surgical indication. DESIGN Retrospective cohort study SETTING Academic tertiary care center PATIENTS Surgically menopausal patients age ≤45 years who underwent minimally invasive hysterectomy with salpingo-oophorectomy. INTERVENTIONS HRT prescription in the 6-week postoperative period. MEASUREMENTS AND MAIN RESULTS Sixty-three patients met inclusion criteria. Of those, 52% (n=33) were prescribed HRT in the 6-week postoperative period. Indications for surgical menopause included pelvic pain/endometriosis (31.7%), gynecological malignancy (20.6%), BRCA gene mutation (17.4%), breast cancer (9.5%), Lynch syndrome (4.8%), and other (15.8%). Eighty percent of pelvic pain patients, 25% of gynecological malignancy, 45% of BRCA patients, 33.3% of breast cancer patients, and 66.6% of Lynch syndrome patients used HRT postoperatively. In patients who utilized HRT postoperatively, 76% were offered preoperative HRT counseling. This is in contrast those who did not utilize HRT postoperatively, in which only 33% of patients were offered HRT counseling (p less then 0.001). Perioperative complications were not predictive of HRT use postoperatively. In patients who did not use HRT postoperatively 13.3% utilized alternative non-hormonal therapy. CONCLUSIONS In patients who underwent premature surgical menopause, 52% utilized HRT postoperatively. Patients with pelvic pain and Lynch syndrome were more likely to use HRT, whereas those with gynecologic or breast malignancy and BRCA gene mutations were less likely to use HRT. Preoperative HRT counseling is associated with postoperative HRT use. Failure of pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate and emtricitabine occurs uncommonly despite perfect adherence, resulting in breakthrough HIV infection. Delayed seroconversion associated with antiretroviral use may complicate the picture, causing uncertainties in interpreting adherence pattern for establishing the true cause of PrEP failure. OBJECTIVES To explore the epidemiological information, clinical characteristics, therapeutic outcomes and temporal progression of laboratory findings in 2019-coronavirus disease (COVID-19) patients exposed to lopinavir. METHODS We collected data from ten COVID-19 patients admitted between January 22, 2020 and February 11, 2020 at Xixi hospital in Hangzhou, China. RESULTS Of ten patients, secondary, tertiary and quartus patients emerged, the incubation period was 3-7 days. Mainly initial symptoms were cough and low fever (37.3-38.0 ℃). An asymptomatic case presented normal radiography, the others existed ground glass opacities. All cases (three transferred, seven discharged) exposed to lopinavir on initial hospitalization. Three patients stopped lopinavir using because of adverse effect, two of them deteriorated, one hospitalized longer than others who with sustained lopinavir using. Levels of potassium, albumin, lymphocyte were low, but increased persistently after treatment. Eosinophil values were low on initial hospitalization, then all returned to normal before discharge. Viral load of SARS-CoV-2, radiography and eosinophil improved continuously in 3-14, 6-8 and 7-9 days, respectively. CONCLUSIONS Increasing eosinophils may be an indicator of COVID-19 improvement. The COVID-19 patients may benefit from sustained lopinavir using. More researches on a larger scale are needed to verify these points. INTRODUCTION The global Guinea Worm Eradication Program has reduced numbers of human infections of Guinea worm disease (dracunculiasis) to 49 cases in four countries. However, infections of domestic animals (dogs and cats) have recently been recognized and are increasing. Typically, Guinea worm (Dracunculus medinensis) transmission occurs via ingestion of copepods from water. Despite several interventions, including tethering of dogs while worms emerge, the number of infected dogs continue to increase. One hypothesis is that dogs could be infected through ingestion of copepods in provisioned water. OBJECTIVES The purpose of this study was to evaluate if copepods can survive in water containers under typical Chadian temperatures. METHODS Four container types (plastic, glass, gourd, and metal) were seeded with copepods and exposed to simulated Chadian temperatures. RESULTS All copepods in the metal containers die within four hours. this website Conversely, after eight hours, live copepods were still present in plastic, glass, and gourd containers.
