Background: Surgical staging procedures of the axilla in initially clinically node-positive (cN +) breast cancer patients receiving neoadjuvant chemotherapy (NACT) vary across countries. Different procedures such as axillary lymph node dissection, sentinel lymph node biopsy, target lymph node biopsy and targeted axillary dissection are currently in use. To date, data on radar reflectors as a non-wire and non-radioactive technique for marking target lymph nodes are limited.

- A study was conducted to evaluate the effects of malaria infection during the first trimester of pregnancy on adverse outcomes for mothers and babies in Kenya, Zambia, and the Democratic Republic of the Congo.
- Using rigorous testing methods, researchers found specific risks such as higher rates of preterm birth and anemia later in pregnancy among affected women.
- The findings suggest that first-trimester malaria is linked to increased prevalence of anemia and highlight the need for more research on its impact on other pregnancy complications like preterm birth and low birth weight.
In our recent study, increased viscosity, delayed mucociliary clearance as well as hyposensitivity/dysesthesia of the nasopharynx seemed to play a relevant role in the pathophysiology of postnasal drip (PND) (1). Earlier concepts of PND, regarding an increased volume of secretions and atopy, do not seem to hold true since our latest analyses showed no significant difference between cases and controls (1). However, to this day its therapy is debated and the evidence for an effective treatment of PND is lacking so far.

Design: The study, a planned prospective, observational secondary analysis of the A-PLUS randomised controlled trial of azithromycin, was conducted in Global Network sites in seven countries: Bangladesh, Pakistan, India (two sites), Kenya, Zambia, the Democratic Republic of Congo and Guatemala.
We report the synthesis of two rotaxanes (1 and 2) whose rings have appended thiourea units for the selective recognition of Cl anions. Rotaxane 1 transports Cl across synthetic lipid bilayers more efficiently than 2, exhibiting EC values of 0.243 mol% 0.
