The striped cucumber beetle (SCB) Acalymma vittatum (F.) is one of the most important pests in North American cucurbit crops. While conventional chemical control methods are usually effective in controlling SCB populations, few alternative control methods are available for organic cucurbit crops.

Article Synopsis
  • The study assessed health-related quality of life (HRQoL) in 84 patients with locally advanced basal cell carcinoma (laBCC) treated with cemiplimab.
  • Patients received cemiplimab every 3 weeks for up to 9 cycles, and HRQoL was evaluated using the QLQ-C30 and Skindex-16 questionnaires at various points.
  • Results showed that 62-90% of patients experienced improvement or maintenance in HRQoL, except for fatigue, which remained a concern throughout the treatment.

Background: Prior to the Food and Drug Administration approval of cemiplimab in 2018, the median overall survival (OS) for adult patients with advanced CSCC receiving systemic therapy was approximately 8 to 15 months. Limited real-world data are available on cemiplimab for this indication in the US.

Patients And Methods: This retrospective cohort study included US patients with advanced CSCC initiating cemiplimab monotherapy in a real-world database (2018-2021).

Introduction: Evidence of patients' experiences of living with advanced basal cell carcinoma (aBCC) are limited, particularly after hedgehog pathway inhibitor (HHI) treatment. We explored the burden of aBCC on symptoms and patients' everyday lives post HHI treatment.

Methods: In-depth, semi-structured, approximately 1-h qualitative interviews of US patients with aBCC and prior HHI treatment were conducted.

Introduction: The efficacy of sarilumab and upadacitinib, in combination with disease-modifying antirheumatic drugs (DMARDs), was demonstrated in phase 3 clinical trials of patients with rheumatoid arthritis (RA) refractive to previous biologic DMARDs. In the absence of head-to-head clinical trials, the matching-adjusted indirect comparison (MAIC) and simulated treatment comparison (STC) estimate the relative efficacy of sarilumab and upadacitinib in patients with RA who had an inadequate response to previous biologic DMARDs.

Methods: Patient-level data for sarilumab were obtained from the TARGET trial (NCT01709578) and published aggregate data for upadacitinib were obtained from the SELECT-BEYOND trial (NCT02706847).

Background: In a phase III, randomised, active-controlled study (EMPOWER-Cervical 1/GOG-3016/ENGOT-cx9; R2810-ONC-1676; NCT03257267) and cemiplimab significantly improved survival versus investigator's choice of chemotherapy among patients with recurrent cervical cancer who had progressed on platinum-based therapy. Here we report patient-reported outcomes in this pivotal study.

Methods: Patients were randomised 1:1 to open-label cemiplimab (350 mg intravenously every 3 weeks) or investigator's choice of chemotherapy in 6-week cycles.

The striped cucumber beetle (SCB) (F.) (Coleptera: Chrysomelidae) is a prime problem in North American cucurbit crops. While certain chemical pesticides efficiently control SCB in conventional cucurbit fields, alternative solutions are required due to the ever-evolving regulations on pesticides.

Introduction: Until recently, patients discontinuing first-line (1L) hedgehog inhibitors (HHIs) for basal cell carcinoma (BCC) had few subsequent treatment options. The objective of this study was to describe the treatment journey and prognosis of patients discontinuing 1L HHI for BCC.

Methods: This was a retrospective cohort study of patients with BCC who discontinued 1L HHI treatment in The US Oncology Network between 1 January 2012 and 1 January 2019 (with follow-up until 1 May 2020).

Genetic diversity at population scale, depends on species life-history traits, population dynamics and local and global environmental factors. We first investigate the effect of life-history traits on the neutral genetic diversity of a single population using a deterministic mathematical model. When the population is stable, we show that semelparous species with precocious maturation and iteroparous species with delayed maturation exhibit higher diversity because their life history traits tend to balance the lifetimes of non reproductive individuals (juveniles) and adults which reproduce.

Background: Technologies used in the processing of whole blood and blood component products, including pathogen reduction, are continuously being adopted into blood transfusion workflows to improve process efficiencies. However, the economic implications of these technologies are not well understood. With the advent of these new technologies and regulatory guidance on bacterial risk-control strategies, an updated systematic literature review on this topic was warranted.

Dispersal is a fundamental and crucial ecological process for a metapopulation to survive in heterogeneous or changing habitats. In this paper, we investigate the effect of the habitat quality and the dispersal on the neutral genetics diversity of a metapopulation. We model the metapopulation dynamics on heterogeneous habitats using a deterministic system of ordinary differential equations.

Purpose: The purpose of this study was to examine the association of patient and prescription factors with statin adherence of patients enrolled a self-insured university health plan.

Methods: We conducted a retrospective, longitudinal analysis of pharmacy claims data from a self-insured university for those enrollees prescribed a statin during a 38-month period (2009-2012). Adherence was calculated as the portion of days covered and was defined as portion of days covered ≥80%.

Altered metabolism is a reemerging hallmark of tumorigenesis. Increased cell proliferation results in metabolic reprogramming to facilitate the needs of the rapidly dividing tumor cells. In addition to increased glucose uptake, tumors also take up increased levels of glutamine.

At the time of this research, there were only two insecticides registered for control of cabbage maggot, Delia radicum L., in rutabaga in Canada, one of which (diazinon) will be deregistered by 2017, and resistance having been reported in some areas for the other (chlorpyrifos). To screen for chemistries to replace these organophosphates, and obtain efficacy data comparable between key vegetable brassica production areas in Canada, four small plot field studies were conducted concurrently in British Columbia, Saskatchewan, Ontario, and Quebec in 2009.

Mowat-Wilson syndrome (MWS) is a rare genetic syndrome characterized by a specific facial gestalt, intellectual deficiency, Hirschsprung disease and multiple congenital anomalies. Heterozygous mutations or deletions in the zinc finger E-box-binding homeobox2 gene (ZEB2) cause MWS. ZEB2 encodes for Smad-interacting protein 1, a transcriptional co-repressor involved in TGF-beta and BMP pathways and is strongly expressed in early stages of development in mice.

Purpose: To report the clinical presentation and outcome of delayed-onset endophthalmitis caused by Moraxella species and to evaluate the eubacterial polymerase chain reaction (PCR) in aqueous humor samples for the microbiologic diagnosis.

Patients And Methods: Seven patients with bleb-related delayed onset-endophthalmitis caused by Moraxella were included in a prospective multicenter study (FRIENDS group, 2004 to 2005). Eubacterial PCR followed by direct sequencing and conventional cultures were carried out on aqueous humor samples taken before the first intravitreal antibiotic injection and on vitreous samples taken during pars plana vitrectomy.
