Social prescribing is a model of care, usually in the community-setting, which aims to address people's unmet social needs. Volunteers support primary health care and community-based care in non-medical roles. However, few studies focus on volunteers in social prescribing, therefore, aimed to synthesize the effect of health or peer volunteer-led interventions on psychosocial and behavioural outcomes for middle-aged and older adults with Type 2 Diabetes Mellitus (T2DM) to inform future work for volunteering in social prescribing.

We examined the effectiveness of Hockey Fans in Training (Hockey FIT), a gender-sensitised lifestyle intervention that engages men with overweight/obesity through their passion as fans of a local sports team, on weight change and other health indicators.
Methods: Pragmatic, cluster randomised trial (aged 35-65 years, body mass index ≥ 27 kg/m) within 42 community-based sites in Canada and the United States, randomly assigned (1:1) to intervention (Hockey FIT) or control (wait-list) and stratified by region.
The megaspore mother cell (MMC) arises from somatic cells in the ovule primordium and enters meiosis to generate four megaspores. Only the most chalazal (functional megaspore, FM) survives, undergoing a series of mitoses to form the female gametophyte. We show that this commitment to the sexual germline requires spatial regulation of ().

- - The study focuses on how proper regulation of communication between cells is essential for the differentiation of cells in plants, particularly in *Arabidopsis thaliana*.
- - Researchers analyzed gene expression in surrounding somatic and germline cells and found that β-1,3-glucan, a polysaccharide, plays a significant role in cell insulation and signaling through channels called plasmodesmata.
- - The presence of β-1,3-glucanase in the female germline disrupted this insulation, allowing for changes that affected gene expression and ultimately halted germline development, indicating its crucial role in successful female gamete formation.
Ambulatory management of congestive heart failure (HF) continues to be a challenging clinical problem. Recent studies have focused on the role of HF clinics, nurse practitioners and disease management programmes to reduce HF readmissions. This pilot study is a pragmatic factorial study comparing a coach intervention, a SMARTPHONE REMINDER system intervention and BOTH interventions combined to Treatment as USUAL (TAU).
