To evaluate the performance of the acute flaccid paralysis (AFP) surveillance system in Ghana’s Upper West Region between 2021 and 2023 against WHO benchmarks in order to identify strengths and weaknesses and sustain Ghana’s progress towards a polio-free future.

Retrospective analysis of routinely collected AFP surveillance data.

The Upper West Region of Ghana, a remote and resource-limited border region with high vulnerability to poliovirus importation and circulation.

All 213 AFP cases reported in the Upper West Region between January 2021 and December 2023.

WHO-recommended AFP surveillance indicators, including non-polio AFP (NP-AFP) rate, stool adequacy rate, timeliness of case notification and investigation, stool specimen transport and condition and non-polio enterovirus (NPENT) isolation rate.

A total of 213 AFP cases were reported in the Upper West region between 2021 and 2023, with an average age of 24 months. The NP-AFP rate was consistently above the WHO target, averaging 26.7 per 100 000 population under 15 years. However, stool adequacy rates varied, averaging 73%, with a notable increase from 51% in 2021 to 97% in 2022 and a decline to 70% in 2023. The proportion of districts meeting both NP-AFP and stool adequacy targets fluctuated, with 64% in 2022 but dropping to 27% in 2023. Timeliness of case reporting remained high (≥94%), while investigations within 48 hours declined to 74% in 2023. Stool specimen transport was weak, with only 6% reaching the laboratory within 3 days of collection in 2023. NPENT isolation exceeded the WHO benchmark of ≥10% throughout the study period, with rates of 12% in 2021, 31% in 2022 and 11% in 2023, confirming specimen integrity and laboratory sensitivity despite transport challenges.

The AFP surveillance system in the region demonstrated high sensitivity, as reflected by the NP-AFP rate, but challenges remain in maintaining stool adequacy and sample transportation standards. Strengthening sample transportation and logistics, as well as addressing district-level disparities in surveillance performance, will be essential to improving the overall quality of AFP surveillance in the region.

Atopic dermatitis (AD) is a chronic, relapsing, heterogeneous skin disease affecting 2%–7% of adults, with roughly 30% having moderate-to-severe disease. AD symptoms, like intense itching and skin pain, carry a substantial disease burden that negatively impacts patients’ quality of life (QoL) and psychosocial well-being. Lebrikizumab is a novel, high-affinity monoclonal antibody that selectively binds to and neutralises interleukin-13 with high potency. Three clinical trials with lebrikizumab (ADvocate 1 and 2; ADhere) demonstrated significant clinical benefit in patients with AD, while the 3-year long-term extension study of lebrikizumab (ADjoin) further demonstrated long-term efficacy and safety in patients with AD. The ADTrust study will evaluate patient well-being, their relationship with their skin, long-term effectiveness, and safety of lebrikizumab, treatment satisfaction, and long-term effect of lebrikizumab treatment on different aspects of patients’ lives, including itch, pain, sleep, fatigue, work impairment and overall QoL among adult patients with moderate-to-severe AD in a real-world setting.

This non-interventional, prospective, observational, real-world evidence study will involve approximately 150 sites across Europe and approximately 1200 adults with moderate-to-severe AD treated with lebrikizumab for 2 years. The primary endpoint is patient well-being assessed by the 5-item WHO Well-Being Index (WHO-5) questionnaire. Key secondary endpoints include clinical effectiveness (Eczema Area and Severity Index and Investigator’s Global Assessment Scale), disease symptomatology and control (Patient-Oriented Eczema Measure, 24-hour peak pruritus, skin pain, fatigue and sleep quality Numerical Rating Scale, and safety and tolerability. Other validated endpoints will evaluate physician-reported and patient-reported QoL and treatment satisfaction (Dermatology Life Quality Index, Treatment Satisfaction Questionnaire-9), patients’ work productivity and impairment (Work Productivity and Activity Impairment (WPAI)-AD) and disease control (AD Control Tool). Novel experimental endpoints will also be evaluated with the aim to assess patients’ relationship with their skin (SkinLove questionnaire), disease control (intensity and frequency of flares) and an Effectiveness Diary^+© (a brief monthly survey on a voluntary basis with the aim to assess the long-term impact of lebrikizumab on three fundamental aspects of the patients’ life: the well-being (WHO-5), the itch intensity (24 hours peak pruritus) and the frequency and intensity of flares). Statistical analyses will be descriptive and explorative and based on observed cases. Missing data imputation may be used to handle missing data for primary endpoints and secondary effectiveness endpoints.

This study will be conducted according to the protocol, which has ethics committee approval (Hamburg Ethic Committee in Germany: 2024-101358-BO-ff), and all applicable laws and regulatory requirements for each participating country. The results will be disseminated through scientific publications and congress presentations.

NCT06815380 (Pre-results).

Guidelines for symptomatic knee osteoarthritis (OA) dictate the initiation of conservative treatment (physical therapy, analgesics and intra-articular injections with corticosteroids) as a first line defence. When conservative treatment fails, the golden standard is invasive joint replacement surgery, but for a substantial group of patients who do not respond to the current conservative treatment, this is not (yet) indicated. The RADIOPHENOL study investigates if denervation of knee sensory (genicular) nerves can serve the gap between conservative and invasive treatment for younger patients and for patients who cannot undergo joint replacement surgery due to comorbid health conditions.

The RADIOPHENOL study is a multicentre unblinded randomised controlled trial with three parallel arms (1:1:1). In total, 192 patients with knee OA Kellgren-Lawrence grades 2–4 but not eligible for joint replacement according to the orthopaedic surgeon due to young age, old age and/or comorbidity or technical reasons are eligible and will be randomised to three groups of 64 patients. Group A: traditional radiofrequency ablation, group B: chemical neurolysis with phenol, group C: conservative medical management. Primary outcome is the Oxford Knee Score at 6 months. Secondary outcomes include Western Ontario and McMaster Universities Osteoarthritis Index, knee pain by numeric rating scale, physical functionality, health-related quality of life, mental health, change in medication use, predictive value of a diagnostic block, procedure time, patient discomfort score during the intervention and adverse events.

The protocol (V.2.0, 15 May 2023), was approved by the Ethics Committee of Amsterdam UMC (NL83410.018.22 – METC2022.0890) on 31 July 2023. We aim to publish our results in international peer-reviewed journals.
