The hallmark of dementia with Lewy bodies (DLB) is the “Lewy body”, an abnormal aggregation of alpha-synuclein found in some areas of the brain. The brain is the organ/system that is most vulnerable to this oxidative damage, and reactive oxygen species can cause neurodegenerative diseases. Different models of mitochondrial deregulation have been compared in DLB. The results are consistent with the hypothesis that alpha-synuclein affects the mitochondria themselves, increasing their sensitivity or leading to cell death through protective (neurosin) and accelerating (cytochrome c) factors. This systematic review suggests that mitochondria play an important role in neurodegeneration and a crucial role in the formation of Lewy bodies. DLB is a disease characterized by abnormal accumulation of alpha-synuclein that could result in the release of cytochrome c and subsequent activation of the apoptotic cascade.

Benefits of Remote-Based Mindfulness on Physical Symptom Outcomes in Cancer Survivors: Systematic Review and Meta-Analysis.
JMIR Cancer
January 2025
Kulliyah of Nursing, International Islamic University Malaysia, Selangor, Malaysia.
Background: Many cancer survivors experience a wide range of symptoms closely linked to psychological problems, highlighting the need for psychological treatment, one of the most popular being mindfulness. The use of the internet has greatly increased in the last decade, and has encouraged the use of remote-based interventions to help people living with cancer access treatment remotely via devices.
Objective: The primary aim of this study was to explore the efficacy of internet-based mindfulness interventions on the physical symptoms of people living with cancer, where physical symptoms are defined as distressing somatic experiences (eg fatigue, insomnia, and pain) regardless of the underlying cause.
The influence of Dexmedetomidine as an additive to local anesthetics in dental procedures: A systematic review.

January 2025
Department of Oral and Maxillofacial Surgery Dental School, University of Pernambuco Arnóbio Marques St., 310 Zip code 50100-130, Recife, PE, Brazil
Background: This review aimed to assess if the use of dexmedetomidine as an additive to local anesthetics promotes greater safety and efficacy than local anesthetics alone in dental procedures.
Material And Methods: the systematic review was structured according to the PICO strategy and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist. Studies were included based on the eligibility criteria, and data from the included studies were collected by one author.

Is efficacy of miniscrew-assisted rapid palatal expansion in mid to late adolescents and young adults related to craniofacial sutures opening? A systematic review and meta-analysis.

Background: Transverse maxillary deficiency is a relatively common type of malocclusion, that if left untreated will probably affect the permanent dentition. Recent investigations have proposed the use of bone-supported miniscrews around the midpalatal suture to expand the palate in late adolescents. The aim of this systematic review was to assess the efficacy of the Miniscrew Assisted Rapid Palatal Expansion (MARPE) technique in young adult patients, by quantifying skeletal expansion in relation to the age of the patient, as well as the impact upon other craniofacial sutures, and to describe the possible dental side effects.
