Some people living with HIV can have chronic lung and breathing issues. We want to learn if the immune system of the nose may lead to these problems. We will collect a sample from the nose using a small strip of paper put in the nose for two minutes. This sample will be tested for inflammation and bacteria. We will do this test in 150 people with HIV and 100 without HIV. We will ask 100 people to come back in 6 months to do the sample again.

Family caregivers of older adults with cognitive impairment experience significant care burden, impacting their mental health and well-being. Studies indicate that heightened caregiver burden can negatively affect the caregiver-patient relationship, leading to increased behavioral and psychological symptoms in patients with cognitive impairment. These symptoms, in turn, increase caregiver burden and worsen their mental health. However, limited evidence characterizes these complex interpersonal dynamics. Therefore, the overall objective of the study is to deeply explore the experiences of family caregivers of individuals with cognitive impairment, with a focus on their mental well-being.

To assess the nature of ideological intuitions citizens use when making informed guesses about other people's political issue positions. In other words, what do people conclude about each other's wider system of political beliefs upon learning that a conversation partner supports (or opposes) a certain policy position or regulation (e.g. support for renewable energy investments, opposition to the death penalty). Intuitions about wider sets of political beliefs may be relevant to political decision making (e.g. voting, candidate appraisal) and in everyday social interactions (deciding which friend-circles to enter, whom to associate with, which clubs, associations to join, ect). The goal of this study is to gain an overview of the prevalence and relative strength of ideological intuitions for a set of 16 different political attitudes and identity markers.

The purpose of this consultative process is to engage a broad set of family planning experts to identify what factors should be prioritized in selecting new family planning metrics at the global, country and programmatic levels.
