Does Cranial Base Angle Make a Difference in the Effectiveness of Functional Orthopedic Treatment? A Retrospective Cohort Study.

The literature suggests that the cranial base angle is considered one of the contributing factors to sagittal jaw malpositions when its relationship with the viscerocranium is examined. Our study aims to compare and evaluate the outcomes of fixed functional orthopedic treatment in patients with mandibular retrognathia across different cranial base groups. Participants were treated at Erciyes University with fixed functional appliances and categorized by CBA into low (<130°), medium (130°-134°), and high (>134°) groups.

Introduction: This study evaluated the dentoskeletal effects of miniscrew-anchored maxillary protraction, which included a mandibular anchorage bar and a night facemask in adolescents.
Methods: A total of 20 growing patients with Class III malocclusion and maxillary deficiency were treated with a hybrid hyrax expander with 2 miniscrews in the maxilla and a mandibular anchor bar supported in 2 miniscrews in the anterior region of the mandible. Class III elastics were used from the maxillary first molars to the mandibular anchorage bar, joining the mandibular miniscrews installed between permanent incisors and canines.
Early biological and psychosocial factors associated with PTSD onset and persistence in youth.

Posttraumatic stress disorder (PTSD) is a debilitating mental health condition that can develop after experiencing or witnessing a traumatic event. While considerable research has investigated PTSD in adults, little is known about the biological, psychological, and social factors that contribute to its onset, development, and persistence in youth. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify longitudinal studies examining factors associated with PTSD status and symptom severity in children and adolescents.

Background: Prematurity and low birth weight (LBW) are the main causes of neonatal mortality in South Africa (SA). Home visits by lay health workers (LHWs) may be effective in addressing this.
Aim: To inform a national guideline on LHW home visits as part of the Global Evidence, Local Adaptation (GELA) project, we conducted a rapid qualitative evidence synthesis exploring the acceptability, feasibility and equitability of this intervention for preterm and LBW babies.

This study presents the first comprehensive assessment of microplastics (MPs) in alcoholic (AB) and non-alcohol (NAB) beverages in South Africa. Beverages in various packaging materials, specifically glass, aluminium, and polyethylene terephthalate (PET) were tested for MP content. The samples were filtered and digested, then stained with Rose Bengal dye to facilitate particle identification, followed by physical and chemical characterisation using stereomicroscopy and micro-Raman spectroscopy, respectively.
