Article Abstract
Background And Aim: While the entire world is still experiencing the dramatic emergency due to SARS-CoV-2, Italy has a prominent position since it has been the locus of the first major outbreak among Western countries. The aim of this study is the evaluation of temporal connection between SARS-CoV-2 positive tests (cases) and deaths in Italy in the first wave of the epidemic.
Methods: A temporal link between cases and deaths was determined by comparing their daily/weekly trends using surveillance data of the period March 2-June 2020.
Results: The monitoring of the cases/deaths evolution during the first wave of the outbreak highlights a striking correlation between infections of a certain week and deaths of the following one. We defined a weekly lethality rate that is virtually unchanged over the entire months of April and May until the first week of June (≈13.6%). Due to the rather low number of cases/deaths, this parameter starts to fluctuate in the following three weeks.
Conclusions: The analysis indicates that the weekly lethality rate is virtually unchanged over the entire first wave of the epidemic, despite the progressive increase of the testing. As observed for the overall lethality, this parameter uniformly presents rather high values. The definition of a temporal link between cases and deaths will likely represent a useful tool for highlighting analogies and differences between the first and the second wave of the pandemic and for evaluating the effectiveness, even if partial, of the strategies applied during the ongoing outbreak.

Objective: To evaluate the real-world treatment practices and survival outcomes of patients with de novo metastatic nasopharyngeal carcinoma (dnMNPC) after the combination of programmed death-1(PD-1) inhibitors with chemotherapy.
Methods: We retrospectively gathered data from patients with dnMNPC who were treated with a combination of chemotherapy and PD-1 inhibitors between August 2019 and August 2023. Kaplan-Meier analysis and Cox proportional hazards regression model were used for statistical analyses.

Head and neck squamous cell carcinoma (HNSCC) is among the most prevalent human malignancies globally, with approximately 887,000 new cases diagnosed each year. Currently, the standard treatment for HNSCC involves surgery, followed by radiotherapy, chemotherapy and immunotherapy. However, despite these available treatments, the survival rate of patients with HNSCC remains low.

Police investigations often give rise to multiple hypothetical pathways for how the crime was conducted. Investigators may develop several hypotheses, often based on different pieces of evidence. It is often the case that investigators have too many potential hypotheses rather than too few.

The study also evaluated changes in critical treatment intervals: onset to door (O2D), door to balloon (D2B) and door to needle (D2N) and assessed 30-day clinical outcomes. This study examined MI care trends in India during the COVID-19 lockdown period, irrespective of patients' COVID-19 infection status.
