AI Article Synopsis

  • Many Parkinson's patients experience long and variable wait times for levodopa to take effect, leading to challenges with motor fluctuations.
  • A study tested a new oral solution of levodopa methyl ester (ME) with benserazide and dispersible Madopar (DM) on 13 fasting patients to assess the timing and effectiveness of these preparations.
  • Results showed that ME and DM had faster onset times compared to standard Sinemet, providing potential benefits for patients needing quicker relief from "off" periods without compromising the duration of effectiveness.

Article Abstract

For many patients with Parkinson disease and levodopa-related motor fluctuations, the latency to onset of action of a single dose of a levodopa preparation may be both long and variable. In an effort to find a more rapidly acting and reliable preparation of levodopa, we therefore studied the efficacy of single doses of an oral solution of 250 mg of levodopa methyl ester (ME) with benserazide, 50 mg and of a molar equivalent dose of dispersible Madopar (DM) (50/200) in 13 patients in the fasting state after overnight drug withdrawal. The response of seven of these patients was compared to that after two Sinemet 25/100. The latency to "on" was equally fast with ME and DM, and significantly faster than after standard Sinemet. The duration of "on" was similar with all three. Because of this more rapid relief of "off" periods, both ME and DM offer a potential clinical advantage over standard preparations of levodopa.

Factors Influencing Preoperative Psychological Resilience in Patients With Traumatic Lower Extremity Fractures.

J Trauma Nurs

January 2025

Author Affiliations: School of Nursing and Health Management, Shanghai University of Medicine & Health Sciences, Shanghai (Mss Jiang and Ying and Drs Xu, Cao, and Zhou); and Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai, China (Ms Liu).

Background: The psychological resilience of patients with traumatic lower extremity fractures is relevant and has been studied in the postoperative rehabilitation phase; yet, few studies have focused on the early preoperative phase.

Objective: This study aims to explore preoperative psychological resilience in patients with traumatic lower extremity fractures.

Methods: This single-center cross-sectional survey design study was conducted over 5 months from December 2022 to April 2023 in a tertiary hospital in Shanghai, China.

Stereotactic Radiosurgery for World Health Organization Grade 2 and 3 Oligodendroglioma: An International Multicenter Study.

Neurosurgery

September 2024

Department of Surgery, Division of Neurosurgery, Centre de recherche du Centre Hospitalier Universitaire de Sherbrooke, Université de Sherbrooke, Sherbrooke, Québec, Canada.

Background And Objectives: Oligodendrogliomas are primary brain tumors classified as isocitrate deshydrogenase-mutant and 1p19q codeleted in the 2021 World Health Organization Classification of central nervous system tumors. Surgical resection, radiotherapy, and chemotherapy are well-established management options for these tumors. Few studies have evaluated the efficacy of stereotactic radiosurgery (SRS) for oligodendroglioma.

This study aimed to evaluate the efficacy of pyrotinib, an orally administered small molecule tyrosine kinase inhibitor, combined with neoadjuvant chemotherapy in treating patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer. Pyrotinib works by inhibiting the HER2 signaling pathway, thereby preventing tumor cell growth. This single-arm clinical trial aimed to assess the total pathological complete response (tpCR; ypT0/is and ypN0) rate as the primary endpoint.

FDA Approval Summary: Tovorafenib for Relapsed or Refractory BRAF-altered Pediatric Low-Grade Glioma.

Clin Cancer Res

January 2025

United States Food and Drug Administration, Silver Spring, Maryland, United States.

On April 23, 2024, FDA granted accelerated approval to tovorafenib, a type II RAF kinase inhibitor, for the treatment of patients 6 months of age and older with relapsed or refractory pediatric low-grade glioma (pLGG) harboring a BRAF fusion or rearrangement, or BRAF V600 mutation. Efficacy was evaluated in FIREFLY-1 (NCT04775485), a single-arm, open-label, multicenter trial that enrolled patients 6 months to 25 years of age with relapsed or refractory pLGG with an activating BRAF alteration who had received prior systemic therapy. The major efficacy outcome measure was radiologic overall response rate (ORR), defined as the proportion of patients with complete response, partial response, or minor response as determined by blinded independent central review using Response Assessment in Pediatric Neuro-Oncology (RAPNO) criteria.

Based on the notion that hypomorphic germline genetic variants are linked to autoimmune diseases, we reasoned that novel targets for cancer immunotherapy might be identified through germline variants associated with greater T-cell infiltration into tumors. Here, we report that while investigating germline polymorphisms associated with a tumor immune gene signature, we identified PKCδ as a candidate. Genetic deletion of PKCδ in mice resulted in improved endogenous antitumor immunity and increased efficacy of anti-PD-L1.
