Response to neoadjuvant chemotherapy leads to better survival outcomes in upper tract urothelial carcinoma.

Objectives: To evaluate the benefit of neoadjuvant chemotherapy (NAC) for patients with high-risk upper tract urothelial carcinoma (UTUC) using a large, well-curated multi-institutional database.

Patients And Methods: This study was a multi-institutional retrospective analysis conducted by the UTUC Collaborative Network (UCAN), combining data from 2276 patients with UTUC who underwent radical nephroureterectomy at seven high-volume tertiary care centres in the United States. The UCAN data were analysed to evaluate the impact of response to NAC on survival outcomes in patients with UTUC.

Implementation outcomes of 1-3-7 focus investigation for malaria in a low transmission setting in Southern Province, Zambia: A mixed methods study.

Eleven countries have been certified as malaria free since 2016, but none of these are in subSaharan Africa where elimination challenges are unique. The 1-3-7 focus investigation approach is an implementation strategy that requires case reporting, case investigation/classification, and focal classification/response to be completed one, three, and seven days, respectively, after index case diagnosis. Real-time short-messaging-service reports are sent at each step to add accountability and data transparency.

Inefficient transfer of diatoms through the subpolar Southern Ocean twilight zone.

The Southern Ocean, a region highly vulnerable to climate change, plays a vital role in regulating global nutrient cycles and atmospheric CO via the biological carbon pump. Diatoms, photosynthetically active plankton with dense opal skeletons, are key to this process as their exoskeletons are thought to enhance the transfer of particulate organic carbon to depth, positioning them as major vectors of carbon storage. Yet conflicting observations obscure the mechanistic link between diatoms, opal and particulate organic carbon fluxes, especially in the twilight zone where greatest flux losses occur.

Long-term health consequences and costs of changes in alcohol consumption in England during the COVID-19 pandemic.

Background And Aims: The COVID-19 pandemic led to changes in alcohol consumption in England. Evidence suggests that one-fifth to one-third of adults increased their alcohol consumption, while a similar proportion reported consuming less. Heavier drinkers increased their consumption the most and there was a 20% increase in alcohol-specific deaths in England in 2020 compared with 2019, a trend continuing through 2021 and 2022.
