Vaccination against SARS-CoV-2 was a crucial public health measure during the COVID-19 pandemic. Among the multiple strategies developed to increase vaccine uptake, governments often employed vaccine mandates. However, little evidence exists globally about the impact of these mandates and their subsequent removal on vaccine uptake, including in Australia, France, Italy and the USA. The aim of this study is to provide a protocol to evaluate and quantify the impact of COVID-19 vaccine mandates and removals on vaccine uptake in these countries, with a specific focus on comparing Australian policies with those from Europe and the USA. Actualising the work outlined in this protocol will help to provide policy and technical guidance for future pandemic preparedness and routine immunisation programmes.
This protocol outlines a retrospective study using existing data sources including Australian Immunisation Register-Person Level Integrated Data Asset for Australia and publicly available data for France, Italy and California (USA). Causal inference methods such as interrupted time series, regression discontinuity design, difference-in-differences, matching and synthetic control will be employed to assess the estimated effects of vaccine mandates and removals on vaccine uptake.
The University of Newcastle’s human research ethics committee has approved the study (reference number: H-2024-0160). Peer-reviewed papers will be submitted, and results will be presented at public health, immunisation and health economic conferences nationally and internationally. A lay summary will be published on the MandEval website.
Chronic wounds pose significant challenges to patients and potentially reduce patients' quality of life. A prospective randomised control trial (RCT) was conducted in Russia between 2018 and 2021 to assess the effectiveness of treating chronic wounds with a high-intensity Erbium: Yttrium Aluminium Garnet (Er:YAG with RecoSMA (Reconstructive Spatially Modulated Ablation module for distributing laser radiation into microbeams) laser technology versus sharp debridement in 144 patients (treatment group N = 71; control N = 73) with diabetic foot, venous and arterial leg ulcers. The median ulcer size at baseline in the treatment and control group was 11 cm2 and 10 cm2 with median ulcer duration of 16 months and 15 months, respectively. The endpoints were the time to achieve a clean wound bed, time to granulation, extent of complete and marginal epithelialisation, change in wound area, presence of bacteria, levels of topical wound pain, and the patients' tolerance of debridement. A difference at p < 0.05 was considered statistically significant. After a 30-day observation period, complete epithelialisation occurred in more than twice as many wounds in the treatment group (56.3%) compared to the control group (26%). The Er:YAG laser was more effective than sharp debridement in clearing wounds of microbial flora, stimulating tissue regeneration, promoting early granulation, marginal epithelialisation and wound healing, suggesting that Er:YAG laser therapy may offer greater benefits than conventional methods of sharp debridement of slow healing wounds.

BackgroundAmong acute stroke patients (ASPs), diabetes mellitus (DM) is associated with a higher risk of death, functional dependency, and recurrence. This study aimed to determine the impact of DM on the 30-day mortality among admitted ASPs in northern Tanzania.
Materials and methodsThis was a hospital-based prospective cohort study performed among ASPs with and without DM who were admitted to Kilimanjaro Christian Medical Centre from November 2022 to May2023. ASPs were followed for 30 days after the onset of an acute stroke to identify the primary outcome, which was all-cause mortality. Descriptive statistics, logistic regression, and survival analysis were conducted,
ResultsOut of 213 ASP, 82 (38.5%) had DM. The overall crude mortality rate was 46.9%. ASPs with DM had a higher mortality rate of 53.7% compared with those without DM (42.7%). A higher proportion of acute stroke patients with DM (84.1%) had a poor outcome (mRS 3-6) (p = 0.038). DM was statistically non-significant for 30-day mortality (aHR 1.56; 95% CI: 0.73–3.32; p = 0.252). However, fever (p = 0.005), severe admission Glasgow coma scale (p = 0.005), severe stroke (p = 0.008), elevated serum creatinine (p = 0.008), and an abnormal respiratory pattern (p = 0.042), were predictors of 30-day mortality,
ConclusionThis study demonstrated a high mortality in ASPs. Although DM did not have a significant impact on 30-day mortality, other factors, such as altered mental state, stroke severity, fever, elevated creatinine, and abnormal respiration, need to be accounted for that may have a significant impact on the mortality in ASPs. These findings highlight the significant burden of DM in stroke patients and underscore the importance of early diagnosis and treatment of ASPs, in the hopes of improving clinical practice and guidelines and reducing morbidity and mortality in Tanzania.
