    Efficacy of oral remdesivir in treating feline infectious peritonitis: a prospective observational study of 29 cats

    Objectives: The primary aim of this prospective observational study was to document clinical progression, survival, remission and relapse in New Zealand cats with feline infectious peritonitis (FIP) that were treated with compounded oral remdesivir with or without initial parenteral remdesivir therapy. The secondary aims were to determine the optimal monitoring protocols and report the adverse effects of treatment and complications associated with FIP. Methods: A total of 29 client-owned cats with a clinical diagnosis of FIP were prospectively recruited. Cats were administered oral remdesivir (30 mg/kg q24h), rounded up to the nearest capsule size as the sole treatment, or after initial parenteral remdesivir (15–30 mg/kg q24h). Rechecks were recommended at weeks 1, 2, 4, 8 and 12 during treatment, and at 2 and 12 weeks after treatment. A full physical examination (including neurological and ophthalmic examination) and point-of-care ultrasound were performed at each recheck. A complete blood count and biochemistry panel were performed at weeks 4, 8, 12 and 24. Molnupiravir was offered as a rescue therapy for cats that relapsed. Results: In total, 25 (86%) cats entered remission and survived beyond 6 months (range 6–27). A total of 22 (75%) cats achieved remission within 84 days while receiving oral remdesivir. Three cats received subsequent molnupiravir rescue therapy to achieve remission. Five cats (20%) experienced relapse: four with non-effusive disease and one with effusive disease. Notably, 4/8 (50%) non-effusive cases relapsed, compared with only 1/20 (5%) with effusive disease. Conclusions and relevance: This study demonstrates that oral remdesivir at a dose rate of 30 mg/kg q24h is an effective treatment for effusive FIP. The survival rate in non-effusive cats was significantly lower; therefore, an increased dose rate or frequency of administration should be considered in these cats. Oral remdesivir is a viable antiviral option where GS-441524 is unavailable.

    Recommended vs. Practice: smallholder fertilizer decisions in central Myanmar
    (MDPI (Basel, Switzerland), 2021-01-14) Thar SP; Farquharson RJ; Ramilan T; Coggins S; Chen D
    Agriculture in Myanmar has substantial development potential given the abundance of land, water, and labor resources in the country. Despite this, agricultural productivity in Myanmar is low and farm incomes are amongst the lowest in Asia. The underperformance of crops and low yield is widely reported to be due to low fertilizer use by smallholders. This study investigated the perceptions of smallholders about fertilizer use for cereal crops by considering their motives and decision making. We reported results of a 600 smallholders’ survey and tested whether the reportedly low fertilizer use by smallholders is generally true for central Myanmar. We compared the fertilizer application timing against recommended “good management practices”. Among the surveyed rice farmers, the average fertilizer applied was much higher than previously reported national average fertilizer rates while the majority of the surveyed maize farmers were found to be applying less than the national recommended rates. With respect to timing, nearly half of the surveyed smallholders were not applying nitrogen at the estimated panicle initiation stage, which is often crucial to increase yield, and the majority (82%) of smallholders were applying phosphorus throughout the growth stages, when earlier applications are desirable. Smallholders may be able to reduce the cost of labor by reducing the number of P applications and avoiding late applications.
