Journal of Clinical Nursing published by John Wiley & Sons Ltd.Kisspeptin1 (KISS1) is a tumor metastatic suppressor, and its increased expression is validated in human placenta trophoblast cells. Nonetheless, the actions of KISS1 in hydrogen peroxide (H2 O2 )-impaired human trophoblast HTR8 cells still remain imprecise. This research aims to uncover whether KISS1 can mitigate H2 O2 -triggered cell injury. HTR8 cells were pretreated with 250 μM H2 O2 for 4 hours; the autophagic markers (Beclin-1 and LC3B), cell viability, invasion and apoptosis were appraised. Real-time quantitative polymerase chain reaction and Western blot trials were enforced for the valuation of KISS1 mRNA and protein levels. PFK15 After si-KISS1 transfection and 3-MA manipulation, the aforesaid biological processes were reassessed for ascertaining the influences of repressed KISS1 in H2 O2 -impaired HTR8 cells. Phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) pathway was eventually estimated. H2 O2 enhanced Beclin-1 and LC3B expression, restricted cell viability, and invasion, and meanwhile caused apoptosis. The elevation of KISS1 evoked by H2 O2 was observed in HTR8 cells. In addition, silencing KISS1 was distinctly annulled the function of H2 O2 in HTR8 cells. Eventually, we observed that the repression of KISS1 triggered the activation of PI3K/AKT/mTOR in HTR8 cells under H2 O2 management. The diverting research unveiled that KISS1 repression eased H2 O2 -caused HTR8 cells injury via mediating PI3K/AKT/mTOR pathway. © 2020 Wiley Periodicals, Inc.The brown planthopper is a notorious rice pest in many areas of Asia. The evolution of insecticide resistance in N. lugens has become to a serious problem in the effective control of this pest in the paddy field. In this article, the current susceptibility of N. lugens field populations to novel mesoionic insecticide triflumezopyrim and major classes of chemical insecticides was determined and compared. The monitoring results indicated that field populations of N. lugens had developed low resistance to triflumezopyrim (resistant ratio, RR 1.3-7.3-fold) during 2015-2018 in China, and the LC50 values varied from 0.05 to 0.29 mg/L. Additionally, during 2017 to 2018, field populations of N. lugens showed high resistance levels to thiamethoxam (RR 456.1-1025.6-fold), imidacloprid (RR 2195.3-6899.0-fold) and buprofezin (RR 1241.5-4521.7-fold), moderate to high resistance levels to dinotefuran (RR 97.6-320.1-fold), clothianidin (RR 69.4-230.1-fold) and isoprocarb (RR 44.1-108.0-fold), and low to moderate level of resistance to chlorpyrifos (RR 12.0-29.7-fold) and nitenpyram (RR 6.9-24.1-fold). In contrast, N. lugens just showed low resistance to sulfoxaflor (RR 3.3-8.5-fold) and etofenprox (RR 5.0-9.1-fold) in the field. Additionally, P450 gene CYP6ER1 was found to be significantly overexpressed in all five field populations of N. lugens collected in 2018 when compared with a laboratory susceptible strain. Our findings will provide useful information to delay the evolution of insecticide resistance in N. lugens. This article is protected by copyright. All rights reserved.

AIMS To determine whether clinical manifestations of IMD have changed due to increased incidence of MenW and MenY. METHODS We performed a retrospective review of IMD cases notified to the Department of Health and Human Services in Victoria, Australia. We compared the period between January 2013 and June 2015 (defined as P1) immediately before the increase in MenW and MenY was noted, with the equal time period of July 2015 to December 2017 (P2), when this increase was observed. RESULTS IMD was notified more frequently in P2 than P1 (1.24 vs 0.53 per 100 000 person-years; p less then  0.001). IMD cases in P2 were older (46 vs 19 years; p less then  0.001), and more likely due to MenW (92/187, 49.2% vs 11/80, 13.8%, p less then  0.001) or MenY (31/187, 16.6% vs 4/80, 5.0%, p = 0.01). IMD cases from P2 were more likely bacteraemic (151/187, 80.7% vs 55/80, 68.8%, p = 0.04), while meningitis (68/187, 36.4% vs 41/80, 51.3%, p = 0.03) and rash (65/181, 35.9% vs 45/78, 57.7%, p = 0.002) were less frequent. ICU admission rates and in-hospital mortality were unchanged. CONCLUSION Alongside an increase in IMD in Victoria, the proliferation of cases of MenW and MenY occurred in older patients, and were more often identified through bacteraemia rather than meningitis or purpura fulminans. Clinicians should be aware of these changes to facilitate earlier identification and treatment of IMD. This article is protected by copyright. All rights reserved.

Vulnerable individuals including those in which vaccinations is contraindicated, may be reliant on normal human immunoglobulin (NHIG) prophylaxis in an aim to prevent disease. This paper will summarise and discuss a tertiary paediatric hospital's clinical experience and the practicalities of administering intramuscular (IM) NHIG to paediatric patients as per the current measles prophylaxis guidelines in Australia. Following potential exposure within the emergency department, 17 paediatric patients (0-15 years) were recommended IM NHIG for prophylaxis. The dose of NHIG ranged from 0.6 to 15 mL and required multiple (2-8) injections. Two patients required sedation for staff to safely administer the injections. Staff involved with these cases reported administering multiple injections to paediatric patients to be a traumatising experience. They also expressed views that the injection of large volumes via the IM route was an impractical method of administration. Based on this experience, we recommend intravenous immunoglobulin be considered when large volumes of NHIG are recommended intramuscularly. © 2020 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).
