Objective: Rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone, once every 3 weeks (R-CHOP21) is commonly used in non-Hodgkin's lymphoma (NHL), but accompanied by pneumonia (PCP) as a fatal treatment complication. This study aims to estimate the specific effectiveness and cost-effectiveness of PCP prophylaxis in NHL undergoing R-CHOP21.
Design: A two-part decision analytical model was developed. Prevention effects were determined by systemic review of PubMed, Embase, Cochrane Library and Web of Science from inception to December 2022. Studies reporting results of PCP prophylaxis were included. Enrolled studies were quality assessed with Newcastle-Ottawa Scale. Costs were derived from the Chinese official websites, and clinical outcomes and utilities were obtained from published literature. Uncertainty was evaluated through deterministic and probabilistic sensitivity analyses (DSA and PSA). Willingness-to-pay (WTP) threshold was set as US$31 315.23/quality-adjusted life year (QALY) (threefold the 2021 per capita Chinese gross domestic product).
Setting: Chinese healthcare system perspective.
Participants: NHL receiving R-CHOP21.
Interventions: PCP prophylaxis versus no prophylaxis.
Main Outcome Measures: Prevention effects were pooled as relative risk (RR) with 95% CI. QALYs and incremental cost-effectiveness ratio (ICER) were calculated.
Results: A total of four retrospective cohort studies with 1796 participants were included. PCP risk was inversely associated with prophylaxis in NHL receiving R-CHOP21 (RR 0.17; 95% CI 0.04 to 0.67; p=0.01). Compared with no prophylaxis, PCP prophylaxis would incur an additional cost of US$527.61, and 0.57 QALYs gained, which yielded an ICER of US$929.25/QALY. DSA indicated that model results were most sensitive to the risk of PCP and preventive effectiveness. In PSA, the probability that prophylaxis was cost-effective at the WTP threshold was 100%.
Conclusion: Prophylaxis for PCP in NHL receiving R-CHOP21 is highly effective from retrospective studies, and routine chemoprophylaxis against PCP is overwhelmingly cost-effective from Chinese healthcare system perspective. Large sample size and prospective controlled studies are warranted.

Objectives: There is conflicting evidence as to whether the combined administration of two vaccines can lead to poorer immunogenicity and reactogenicity. The co-administration of the Omicron-adapted COVID-19 vaccine from Novavax (NVX-CoV2601) and a 20-valent pneumococcal conjugate vaccine (PCV20) has not been previously investigated.
Methods: In this randomised, double-blind, placebo-controlled, non-inferiority trial, immunocompetent participants aged ≥60 years were randomised in a 1:1:1:1 ratio to four groups: NVX-CoV2601 plus PCV20 (combination group); NVX-CoV2601 plus placebo (NVX-only group); PCV20 plus placebo (PCV20-only group); or placebo plus placebo (placebo group).

Background: Human papillomavirus (HPV), a common sexually transmitted infection in the US, contributes to oropharyngeal and urogenital cancers. To improve HPV vaccine uptake, quality improvement (QI) interventions that address barriers to vaccination in primary care may help. This study aims to understand pediatric primary care providers' (PCP) perspectives on participating in an HPV QI intervention that utilized practice facilitation to improve HPV vaccine uptake in pediatric primary care clinics.

Objectives: The objective of this study was to develop and validate an automated solid-phase extraction (SPE) coupled with ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for the detection of sodium pentachlorophenolate (PCP-Na) residues on cutting boards. Given the potential hazards and environmental persistence of PCP-Na, a sensitive and reliable method is crucial for monitoring its residues in food contact materials to ensure consumer safety.
Methods: Wood shavings from cutting boards were extracted using 10% methanol in water, followed by purification using an automated SPE system.

Background: Pneumocystis jirovecii pneumonia (PCP) is an opportunistic infection in patients undergoing immunosuppressive therapy, such as glucocorticoid (GC) medication, for systemic autoimmune diseases like systemic lupus erythematosus (SLE). Despite the confirmed effectiveness of PCP prophylaxis, its clinical administration, especially in conjunction with GC dosage, remains unclear. We aimed to describe the clinical practice of PCP prophylaxis in association with SLE in Japan, evaluate the relationship between GC dosage and PCP prophylaxis, and explore the practice patterns associated with PCP prophylaxis.
