RESUMEN

OBJECTIVE: To investigate short-term efficacy and safety of a novel lipid ibuprofen formulation 1200 mg/day compared with standard ibuprofen 1200 mg/day and 2400 mg/day in episodic knee arthralgia/flaring pain. DESIGN: Multicentre, randomised, double-blind, 3-arm, non-inferiority trial conducted at 27 primary care centres. Adults with ≥1 knee flare episode within 12 months were recruited within 24 h of new flare with pain severity ≥5 on a 0-10 numerical rating scale (NRS). Primary outcome was change from baseline in WOMAC pain subscale over 5 days. Main secondary outcome was Gastrointestinal Symptom Rating Scale (GSRS) change from baseline. Other endpoints included assessment of WOMAC total subscale scores and self-reported NRS for pain, subject nominated activity, stiffness and swelling. RESULTS: 462 patients were enrolled (58.9% males; mean age 52.2 years). Treatment allocation comprised 148 lipid 1200 mg, 155 soft-gel 1200 mg, 159 soft-gel 2400 mg. WOMAC pain subscale scores decreased in all groups, with lipid 1200 mg being non-inferior to soft-gel 1200 mg (adjusted mean difference -0.26 [95% confidence interval [CI] -0.69, 0.17]) and to soft-gel 2400 mg (difference 0.19 [95% CI -0.24, 0.62]). No differences were seen in mean GSRS total scores. NRS secondary endpoints suggested greater improvements in the lipid 1200 mg group compared to soft-gel 1200 mg, with similar results to soft-gel 2400 mg. The most frequent drug-related adverse events (AEs) were gastrointestinal (GI) disorders, with statistically fewer events for lipid 1200 mg vs soft-gel 2400 mg (P = 0.01, post-hoc analysis). CONCLUSIONS: Ibuprofen 1200 mg/day lipid formulation was non-inferior to standard ibuprofen soft-gel capsules 1200 mg and 2400 mg/day in relieving flaring knee pain. NRS endpoints showed lipid 1200 mg was numerically similar to soft-gel 2400 mg. TRIAL REGISTRATION NUMBER: EudraCT number: 2014-004254-33.

RESUMEN

OBJECTIVES: To investigate the efficacy and safety of CS1002, an over-the-counter cough treatment containing diphenhydramine, ammonium chloride and levomenthol in a cocoa-based demulcent. DESIGN: A multicentre, randomised, parallel group, controlled, single-blinded study in participants with acute upper respiratory tract infection-associated cough. SETTING: 4 general practitioner (GP) surgeries and 14 pharmacies in the UK. PARTICIPANTS: Participants aged ≥18 years who self-referred to a GP or pharmacist with acute cough of <7 days' duration. Participant inclusion criterion was cough severity ≥60 mm on a 0-100 mm visual analogue scale (VAS). Exclusion criteria included current smokers or history of smoking within the past 12 months (including e-cigarettes). 163 participants were randomised to the study (mean participant age 38 years, 57% females). INTERVENTIONS: Participants were randomised to CS1002 (Unicough) or simple linctus (SL), a widely used cough treatment, and treatment duration was 7 days or until resolution of cough. MAIN OUTCOME MEASURES: The primary analysis was intention-to-treat (157 participants) and comprised cough severity assessed using a VAS after 3 days' treatment (prespecified primary end point at day 4). Cough frequency, sleep disruption, health status (Leicester Cough Questionnaire (LCQ-acute)) and cough resolution were also assessed. RESULTS: At day 4 (primary end point), the adjusted mean difference (95% CI) in cough severity VAS between CS1002 and SL was -5.9 mm (-14.4 to 2.7), p=0.18. At the end of the study (day 7) the mean difference in cough severity VAS was -4.2 mm (-12.2 to 3.9), p=0.31. CS1002 was associated with a greater reduction in cough sleep disruption (mean difference -11.6 mm (-20.6 to 2.7), p=0.01) and cough frequency (mean difference -8.1 mm (-16.2 to 0.1), p=0.05) compared with SL. There was greater improvement in LCQ-acute quality of life scores with CS1002 compared with SL: mean difference (95% CI) 1.2 (0.05 to 2.36), p=0.04 after 5 days' treatment. More participants prematurely stopped treatment due to cough improvement in the CS1002 group (24.4%) compared with SL (10.7%; p=0.02). Adverse events (AEs) were comparable between CS1002 (20.5%) and SL (27.6%) and largely related to the study indication. 6 participants (7%) in the CS1002 group reduced the dose of medication due to drowsiness/tiredness, which subsequently resolved. These events were not reported by participants as AEs. CONCLUSIONS: Although the primary end point was not achieved, CS1002 was associated with greater reductions in cough frequency, sleep disruption and improved health status compared with SL. TRIAL REGISTRATION NUMBER: EudraCT number 2014-004255-31.

RESUMEN

Wild populations of nonhuman primates live in regions of sylvatic arbovirus transmission. To assess the status of arbovirus transmission in Bornean forests and the susceptibility of wild orangutans to arboviral infection, blood samples of wild orangutans, semi-captive orangutans, and humans were examined. Samples were tested by plaque reduction neutralization test for antibodies to viruses representing three families (Flaviviridae, Alphaviridae, and Bunyaviridae), including dengue-2, Japanese encephalitis, Zika, Langat, Tembusu, Sindbis, Chikungunya, and Batai viruses. Both wild and semi-captive orangutan groups as well as local human populations showed serologic evidence of arbovirus infection. The presence of neutralizing antibodies among wild orangutans strongly suggests the existence of sylvatic cycles for dengue, Japanese encephalitis, and sindbis viruses in North Borneo. The present study demonstrates that orangutans are susceptible to arboviralinfections in the wild, although the impact of arboviral infections on this endangered ape remain unknown.

RESUMEN

Diagnosis of active mycobacterial disease in orangutans (Pongo pygmaeus) has been impeded by high levels of non-specific intradermal skin test reactivity to mycobacterial antigens. This may be due in part to cross reactivity between antigens, tuberculin concentrations used or other species-specific factors. Antigen 85 (Ag85) complex proteins are major secretory products of actively growing mycobacteria, and measurement of serum Ag85 could provide a method for determining active mycobacterial infections that was not dependent on host immunity. Serum Ag85 was measured by dot-immunobinding assay using monoclonal anti-Ag85, purified Ag85 standard and enhanced chemiluminescence technology in coded serum samples from 14 captive orangutans from a zoo in Colorado, 15 semi-captive orangutans in Malaysia, and 19 free-ranging wild orangutans in Malaysia. Orangutans from Colorado (USA) were culture negative for Mycobacterium tuberculosis and M. avium, although all had laboratory suspicion or evidence of mycobacterial infection; median serum Ag85 was 10 microU/ml (range, <0.25-630 microU/ml). Of the semi-captive orangutans, six were skin test reactive and two were culture positive for M. avium on necropsy. Median serum Ag85 for this group was 1,880 microU/ml (0.75-7,000 microU/ml), significantly higher than that of Colorado zoo or free-ranging Malaysian orangutans. Median serum Ag85 in the latter group was 125 microU/ml (range, 0.75-2,500 microU/ml). These data suggest that suggest that additional studies using more specific reagents and more samples from animals of known status are appropriate.

RESUMEN

The Field Veterinary Program (FVP) of the Wildlife Conservation Society (WCS) was created in 1989 to combat the wildlife disease and health problems that increasingly complicate the process of wildlife conservation. The FVP provides veterinary services for the more than 300 WCS conservation projects located in more than 50 countries around the world. Most of these projects are in tropical regions and many have a wildlife/domestic livestock component. Wildlife health care provided by the FVP staff includes (1) identifying critical health factors; (2) monitoring health status; (3) crisis intervention; (4) developing and applying new technologies; (5) animal handling and welfare concerns; and (6) training. Additionally, the staff of the FVP give expert advice to many governmental and non-governmental agencies that are involved in setting policies directly related to wildlife health and conservation issues. In this paper, two FVP projects are presented as examples of studies that have increased our understanding of the role wildlife diseases may play in the health of livestock and human populations, as well as the role humans and livestock may play in the health of wildlife populations. Examples of the collaborative work between the FVP staff and scientists from many disciplines (e.g., acarologists, mycobacterium experts, ecologists, and biologists) are also presented.

RESUMEN

Wild primate populations, an unexplored source of information regarding emerging infectious disease, may hold valuable clues to the origins and evolution of some important pathogens. Primates can act as reservoirs for human pathogens. As members of biologically diverse habitats, they serve as sentinels for surveillance of emerging pathogens and provide models for basic research on natural transmission dynamics. Since emerging infectious diseases also pose serious threats to endangered and threatened primate species, studies of these diseases in primate populations can benefit conservation efforts and may provide the missing link between laboratory studies and the well-recognized needs of early disease detection, identification, and surveillance.
