Article
Clozapine treatment for schizophrenia is typically long-term and is associated with a high rate of diabetes. Mental health and diabetes specialist teams at a local hospital in Australia have undertaken a series of joint specialist case conferences (JSCCs) where the diabetes team works with the psychiatry team to improve diabetes management. In this...

We performed a systematic review and meta-analysis of SARS-CoV-2 serology studies to estimate time-dependent sensitivity for a large set of serological assays. We find that seroreversion depends strongly on the antigen and the analytic technique of the assay. We estimate the average time-varying sensitivity for different types of assays, as defined...
Article
We estimated the degree to which language used in the high profile medical/public health/epidemiology literature implied causality using language linking exposures to outcomes and action recommendations; examined disconnects between language and recommendations; identified the most common linking phrases; and estimated how strongly linking phrases...

Background Retraction is the final safeguard against research error/misconduct. In principle, retraction exists to prevent serious issues identified in published research through post-publication review. Our study investigated the citing of clinical research papers retracted during the COVID-19 pandemic. Methods We used the Retraction Watch databa...
Article
Background: Multiple vaccines against Covid-19 have passed through phase-3 trials; however, concerns have been raised about alleged excessive similarity of efficacy across age groups for the Sputnik V vaccine. Study Question: How likely are the observed efficacies for all age subgroups to fall within the range of by-age efficacies claimed for th...

Introduction Avoidance of health services, in particular hospital and community services, is problematic for people with diabetes. Evidence has demonstrated that such missed attendances are associated with worse health, faster declines in functioning, and higher rates of mortality long-term. This paper investigated the impact of the pandemic on hea...

The cost and comorbidity of obesity in hospitalized inpatients, is less known. A retrospective study of patients presenting to a large district hospital in Western Sydney (April 2016‐February 2017) using clinical, pathological as well as diagnostic coding data for obesity as per ICD‐10. Of 43 212 consecutive hospital presentations, 390 had an obesi...

We read with interest the paper written by Savaris et al. entitled “Stay-at-home policy is a case of exceptional fallacy: an internet-based ecological study”[1]. We believe that the topic of whether non-pharmaceutical interventions (NPIs) have an impact on COVID-19 mortality is a key metric that is important to measure, and applaud the authors for...
Article
The small sample size (n=10) and the sample’s composition have not been justified and introduce a lack of representativeness. Brauner et al. [2] (n=41), along with others, present contradictory results with bigger samples that are not discussed in the manuscript. The authors do not present adequate reasoning for such a small pool of data and exclud...

An important unknown during the coronavirus disease-2019 (COVID-19) pandemic has been the infection fatality rate (IFR). This differs from the case fatality rate (CFR) as an estimate of the number of deaths and as a proportion of the total number of cases, including those who are mild and asymptomatic. While the CFR is extremely valuable for expert...
