We derive an exact upper bound on the epidemic overshoot for the Kermack-McKendrick SIR model. This maximal overshoot value of 0.2984 · · · occurs at [Formula: see text]. In considering the utility of the notion of overshoot, a rudimentary analysis of data from the first wave of the COVID-19 pandemic in Manaus, Brazil highlights the public health hazard posed by overshoot for epidemics with near 2. Using the general analysis framework presented within, we then consider more complex SIR models that incorporate vaccination.

Assessing Willingness to Pay for IVF Among Infertile Women in Greece: A Single-Center Case Study.
Health Sci Rep
January 2025
Healthcare Management Program, School of Social Sciences Hellenic Open University Patras Greece.
Background And Aims: In recent years, In Vitro fertilization (IVF) science has grown by leaps and bounds in the field of assisted reproduction, helping millions of couples worldwide. The aim of this study is to examine the extent to which infertile women are willing to pay for IVF services in Greece.
Methods: Through the distribution of questionnaires, willingness to pay (WTP) is recorded according to IVF success rates, and the relationship between WTP and the respondents' demographic characteristics is analyzed.
Causal Estimands for Analyses of Averted and Avertible Outcomes due to Infectious Disease Interventions.
Epidemiology

Center for Communicable Disease Dynamics, Department of Epidemiology, Harvard T.H. Chan School of Public Health, Boston, Massachusetts, USA.
During the coronavirus disease (COVID-19) pandemic, researchers attempted to estimate the number of averted and avertible outcomes due to vaccination campaigns to quantify public health impact. However, the estimands used in these analyses have not been previously formalized. It is also unclear how these analyses relate to the broader framework of direct, indirect, total, and overall causal effects under interference.

Vaccines (Basel)
January 2025
Division of Infectious Diseases, Cincinnati Children's Hospital Medical Center, 3333 Burnet Avenue, Cincinnati, OH 45229, USA.
Background: Noroviruses, which cause epidemic acute gastroenteritis, and parasites, which lead to malaria, are two infectious pathogens that pose threats to public health. The protruding (P) domain of norovirus VP1 and the αTSR domain of the circumsporozoite protein (CSP) of sporozoite are the glycan receptor-binding domains of the two pathogens for host cell attachment, making them excellent targets for vaccine development. Modified norovirus P domains self-assemble into a 24-meric octahedral P nanoparticle (P NP).

Justifying a proposed government regulation intended to reduce firearm violence requires a conceptually sound estimate of the monetized value of that impact and how that value is distributed across the population. Some previous estimates do not serve as a valid basis for policy evaluation or are out of date. A nationally representative survey was conducted by the AP-NORC Center for Public Affairs Research in August 2022 (n = 660).

Background: Pancreatic cancer (PDAC: pancreatic ductal adenocarcinoma, the commonest form), a lethal disease, is best treated with surgical excision but is feasible in less than a fifth of patients. Around a third of patients presentlocally advanced, inoperable, non-metastatic (laPDAC), whose stadrd of care is palliative chemotherapy; a small minority are down-sized sufficiently to enable surgical excision. We propose a phase II clinical trial to test whether a combination of standard chemotherapy (gemcitabine & nab-Paclitaxel: GEM-NABP) and repurposing All Trans Retinoic Acid (ATRA) to target the stroma may extend progression-free survival and enable successful surgical resection for patients with laPDAC, since data from phase IB clinical trial demonstrate safety of GEM-NABP-ATRA combination to patients with advanced PDAC with potential therapeutic benefit.
