RESUMO

BACKGROUND: Cardiovascular disease (CVD) is one of the world's leading causes of increased morbidity and mortality. Current interventions for CVD, including percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass grafting (CABG), carry certain risks and complications, which may also affect the patient's quality of life. It is important to minimize those risks and complications while speeding up the recovery. Insulin Growth Factor-1 (IGF-1) is a growth factor responsible for cellular migration, proliferation, differentiation, and angiogenesis, which supports cardiovascular regeneration. METHODS: In light of the current trend of regenerative medicine, the present review aims to pool data relating to the incorporation of IGF-1 in regenerative medicine and provide input on the current research gaps and concerns arising on translating this approach from benchwork into clinical settings. RESULTS: Using the keywords IGF-1 'OR' Insulin Growth Factor 1 'AND' Mesenchymal Stem Cells 'AND' Tissue Healing from 2009 to 2020, we identified 160 and 52 from Medline and PubMed, screening out 202 articles due to non-fulfilment of the inclusion criteria. CONCLUSION: Incorporating IGF-1 into regenerative and personalized medicine may be promising for treating CVD; however, the concerns include the role of IGF-1 in inducing cancer growth and its ability to migrate to the specific site of injury, especially for those who present with multiple pathologies should be addressed prior to its translation from bench work into clinical settings.

RESUMO

Stroke remains a leading cause of adult disability, and it decreases the health-related quality of life due to functional disability and poor functional recovery in stroke. Tai Ji has been recently introduced to overcome disabilities. This review aims to explain the effects of Tai Ji on functional recovery in stroke patients, linking it to current approaches, concepts and therapies such as Bobath and proprioceptive neuromuscular facilitation techniques. A compilation of recent literature on Tai Ji's use in stroke rehabilitation from Google scholar and PubMed Central (2018 to 2022). The benefits of Tai Ji in stroke functional recovery were studied and explained based on its similarity in concepts to current conventional stroke rehabilitation approaches. There were few randomized controlled trials on Tai Ji in functional recovery among stroke patients. However, all literature identified Tai Ji as beneficial in stroke rehabilitation. However, there was no literature on explaining the Tai Ji movement based on current conventional stroke rehabilitation approaches. Tai Ji carries similar theories to the current neurorehabilitation approach. Tai Ji can be modified and incorporated into stroke rehabilitation programs based on patients' needs to produce promising outcomes.

RESUMO

BACKGROUND: Pregnant women have an increased risk of urinary incontinence (UI), affecting their quality of life (QoL). This study aims to determine UI and its relationship with QoL among incontinent pregnant women. METHODS: This was a cross-sectional study in a semi-urban primary care clinic in Selangor, Malaysia, among pregnant women aged 18 years old and above. The validated study instruments consisted of questions on socio-demography, the International Consultation on Incontinence Questionnaire-UI Short Form (ICIQ-UI SF) to determine UI and the International Consultation on Incontinence Questionnaire Lower Urinary Tract Symptoms Quality of Life Module (ICIQ-LUTSQoL) to assess their QoL. A generalised linear model was used to determine the association between the continent and incontinent pregnant women with QoL. RESULTS: Of the approached 610 respondents, 440 consented to participate in the study, resulting in a response rate of 72.1%. The mean age was 29.8 years old (SD 4.69) with 82.2% (n = 148) having stress UI. Significant independent factors related to the decreased QoL were mid to late trimester (OR 3.06, 95% CI 1.48-6.32), stress UI, (OR 6.94, 95%CI 4.00-12.04) and urge UI (OR3.87, 95%CI 0.48-31.28). Non-Malay improved QoL (OR 0.29, 95% CI 0.16-0.52). CONCLUSIONS: All types of UI significantly affecting pregnant women's QoL. This information is useful in enhancing antenatal management at the primary care level, whereby they should be screened for UI and provided with effective early intervention to improve their QoL.

RESUMO

Parkinson's disease (PD) is a neurodegenerative disorder defined by progressive deterioration of dopaminergic neurons in the substantia nigra pars compacta (SNpc). Dental pulp stem cells (DPSCs) have been proposed to replace the degenerated dopaminergic neurons due to its inherent neurogenic and regenerative potential. However, the effective delivery and homing of DPSCs within the lesioned brain has been one of the many obstacles faced in cell-based therapy of neurodegenerative disorders. We hypothesized that DPSCs, delivered intranasally, could circumvent these challenges. In the present study, we investigated the therapeutic efficacy of intranasally administered DPSCs in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced mouse model of PD. Human deciduous DPSCs were cultured, pre-labelled with PKH 26, and intranasally delivered into PD mice following MPTP treatment. Behavioural analyses were performed to measure olfactory function and sensorimotor coordination, while tyrosine hydroxylase (TH) immunofluorescence was used to evaluate MPTP neurotoxicity in SNpc neurons. Upon intranasal delivery, degenerated TH-positive neurons were ameliorated, while deterioration in behavioural performances was significantly enhanced. Thus, the intranasal approach enriched cell delivery to the brain, optimizing its therapeutic potential through its efficacious delivery and protection against dopaminergic neuron degeneration.

RESUMO

BACKGROUND: Parkinson's disease (PD) is a neurodegenerative disease caused by the loss of dopaminergic (DA-ergic) neurons in the substantia nigra (SN) and represented as a huge threat to the geriatric population. Cell replacement therapies (CRTs) have been proposed as a promising strategy to slow down or replace neuronal loss. Among the widely available cell sources, dental pulp stem cells (DPSCs) portray as an attractive source primarily due to their neural crest origin, ease of tissue procurement and less ethical hurdles. MATERIALS AND METHODS: We first demonstrated the in vitro differentiation ability of DPSCs towards DA-ergic-like cells before evaluating their neuro-protection/neuro-restoration capacities in MPTP-induced mice. Transplantation via intrathecal was performed with behavioural assessments being evaluated every fortnight. Subsequent analysis investigating their immuno-modulatory behaviour was conducted using neuronal and microglial cell lines. RESULTS: It was apparent that the behavioural parameters began to improve corresponding to tyrosine hydroxylase (TH), dopamine transporter (DAT) and dopamine decarboxylase (AADC) immunostaining in SN and striatum as early as 8-week post-transplantation (P < 0·05). About 60% restoration of DA-ergic neurons was observed at SN in MPTP-treated mice after 12-week post-transplantation. Similarly, their ability to reduce toxic effects of MPTP (DNA damages, reactive oxygen species and nitric oxide release) and regulate cytokine levels was distinctly noted (P < 0·05) upon exposure in in vitro model. CONCLUSIONS: Our results suggest that DPSCs may provide a therapeutic benefit in the old-aged PD mice model and may be explored in stem cell-based CRTs especially in geriatric population as an attempt towards 'personalized medicine'.
