This paper presents a demonstration of the feasibility of fabricating micro-cantilever harvesters with extended stress distribution and enhanced bandwidth by exploiting an M-shaped two-degrees-of-freedom design. The measured mechanical response of the fabricated device displays the predicted dual resonance peak behavior with the fundamental peak at the intended frequency. This design has the features of high energy conversion efficiency in a miniaturized environment where the available vibrational energy varies in frequency. It makes such a design suitable for future large volume production of integrated self powered sensors nodes for the Internet-of-Things.

Objective: The public health nutrition workforce is well-placed to contribute to bold climate action, however tertiary educators are seeking practical examples of how to adequately prepare our future workforce. This study examines the responses of university students engaged in a co-designed planetary health education workshop as part of their public health nutrition training.
Design: A mixed-methods approach was used to collect and interpret student responses to four interactive tasks facilitated during an in-person workshop.

Objective: This study assessed the association between baseline sociodemographic variables, body composition and 4-year changes in the intake of food groups, including sugar sweetened beverages (SSBs) among children, after implementation of the health promotion levy.
Design: Prospective cohort study.
Setting: 10 schools in North West Province, South Africa.

Objective: Humanitarian aid, including food aid, has increasingly shifted towards provision of cash assistance over in-kind benefits. This paper examines whether food security mediates the relationship between receipt of humanitarian cash transfers and subjective wellbeing among Syrian refugee youth in Jordan.
Design: Secondary analysis of the 2020-21 Survey of Young People in Jordan, which is nationally representative of Syrian youth aged 16-30.

Objectives: The objective was to investigate the role of double extraction in reducing data errors in evidence synthesis for pharmaceutical and non-pharmaceutical interventions.
Design: Crossover randomized controlled trial (RCT).
Setting: University and hospital with teaching programs in evidence-based medicine.

Background: Monkeypox (Mpox), is a disease of global public health concern, as it does not affect only countries in western and central Africa.
Aim: To assess Burundi healthcare workers (HCWs)s' level of knowledge and confidence in the diagnosis and management of Mpox.
Methods: We conducted a cross-sectional study an online survey designed mainly from the World Health Organization course distributed among Burundi HCWs from June-July 2023.
