Background: The uptake of HIV partner status notification remains limited in low- and lower-middle-income countries. This mixed-methods systematic review aims to summarize the barriers and facilitators of HIV partner status notification in these settings.

Methods: We searched PubMed, Embase, CINAHL, PsychINFO, Scopus, and Web of Science from January 01, 2000, to August 31, 2023, for empirical qualitative and quantitative studies.

Ammonium (NH) enhances plant defense mechanisms but can be phytotoxic as the sole nitrogen source. To investigate the impact of a balanced NH and NO ratio on plant defense parameters without adverse effects, cucumber plants (Cucumis sativus L.) were grown under control (14 mM NO + 2 mM NH) and elevated level of NH (eNH, 8 mM NO+ 8 mM NH).

Background: Pre-exposure prophylaxis (PrEP) significantly reduces HIV transmission, but it is not commonly prescribed in Iran. Therefore, this study aimed to identify facilitators and barriers to PrEP use among four key populations (KPs) in Iran.

Methods: We conducted in-depth qualitative interviews with female sex workers (FSW), men who have sex with men (MSM), people who inject drugs (PWID), and sexual partners of people living with HIV (PLHIV) to obtain deep insights into the participants' experiences, beliefs, and viewpoints.

Article Synopsis
  • Hepatitis B virus (HBV) infection is a significant public health issue among people who inject drugs (PWID), highlighting the importance of testing and vaccination to reduce infection rates and chronic health issues.
  • A study of 2,684 PWID in Iran revealed that only 14.2% reported having been tested for HBV, while 16.4% had been vaccinated, with factors such as academic education and a history of homelessness influencing these rates.
  • The findings indicate a crucial need to identify and overcome barriers preventing PWID from accessing HBV testing and vaccination to alleviate the impact of HBV within this vulnerable demographic.

Real-time and non-invasive measurements of tissue concentrations of oxyhemoglobin (HbO2) and deoxyhemoglobin (HbR) are invaluable for research and clinical use. Frequency-domain near-infrared spectroscopy (FD-NIRS) enables non-invasive measurement of these chromophore concentrations in human tissue. We present a small form factor, dual-wavelength, miniaturized FD-NIRS instrument for absolute optical measurements, built around a custom application-specific integrated circuit and a dual-slope/self-calibrating (DS/SC) probe.
