Agbulut N. Assessing nerve injuries in oral surgery: a survey-based study on prevention and management. Med Oral Patol Oral Cir Bucal 2025; 30:e462-e468. [PMID: 40121682 PMCID: PMC12019647 DOI: 10.4317/medoral.26995] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2024] [Accepted: 02/17/2025] [Indexed: 03/25/2025] Open
Abstract
BACKGROUND Understanding and mitigating iatrogenic nerve injuries, specifically IAN and LN, is crucial in the field of oral and maxillofacial surgery. These injuries may lead to profound sensory deficits, pain syndromes, and impaired quality of life for patients. This study aims to assess the prevention and management practices for inferior alveolar nerve and lingual nerve injuries among dental professionals. By gathering data through a survey, the study seeks to evaluate current experiences, awareness, and protocols, ultimately contributing to improved guidelines for nerve injury management. MATERIAL AND METHODS This cross-sectional study utilized an online survey distributed via Turkish Dental Association to registered dentists and specialists. The predictor variables were the procedure types associated with nerve injuries. The main outcome variables were preventive measures and patient management strategies. Demographic profiling including age, years in profession, specialty, and type of current workplace were determined as covariates. RESULTS 1477 respondents provided complete answers, with questions addressing demographics, nerve injury incidents, preventive measures, and management strategies. The most reported IAN and LN injuries were linked to dental implant surgery (n=1067), mandibular third molar surgery (n=958), and local anesthesia applications (n=459). Interestingly, more than 30% of participants reported no experience with nerve injuries. For preventive measures in tooth extraction, 281 respondents performed coronectomies, and in implant surgery over 80% of the participants evaluated tomographic images in high-risk cases. Most common management strategies for paresthesia included vitamin B12 (n=1093) and NSAIDs (n=1051). The use of gabapentin, and non-medical treatments like biofeedback and alternative therapies were rarely employed. CONCLUSIONS The survey revealed a diverse range of practices regarding nerve injury prevention and management, emphasizing the need for evidence-based approaches and consensus guidelines. Understanding current practices for managing IAN and LN injuries can inform future guidelines, reduce complications, and improve patient outcomes in oral and maxillofacial surgery.

Optimizing Peripheral Nerve Regeneration: Surgical Techniques, Biomolecular and Regenerative Strategies-A Narrative Review. Int J Mol Sci 2025; 26:3895. [PMID: 40332790 PMCID: PMC12027958 DOI: 10.3390/ijms26083895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2025] [Revised: 04/09/2025] [Accepted: 04/18/2025] [Indexed: 05/08/2025] Open
Abstract
Peripheral nerve injury disrupts the function of the peripheral nervous system, leading to sensory, motor, and autonomic deficits. While peripheral nerves possess an intrinsic regenerative capacity, complete sensory and motor recovery remains challenging due to the unpredictable nature of the healing process, which is influenced by the extent of the injury, age, and timely intervention. Recent advances in microsurgical techniques, imaging technologies, and a deeper understanding of nerve microanatomy have enhanced functional outcomes in nerve repair. Nerve injury initiates complex pathophysiological responses, including Wallerian degeneration, macrophage activation, Schwann cell dedifferentiation, and axonal sprouting. Complete nerve disruptions require surgical intervention to restore nerve continuity and function. Direct nerve repair is the gold standard for clean transections with minimal nerve gaps. However, in cases with larger nerve gaps or when direct repair is not feasible, alternatives such as autologous nerve grafting, vascularized nerve grafts, nerve conduits, allografts, and nerve transfers may be employed. Autologous nerve grafts provide excellent biocompatibility but are limited by donor site morbidity and availability. Vascularized grafts are used for large nerve gaps and poorly vascularized recipient beds, while nerve conduits serve as a promising solution for smaller gaps. Nerve transfers are utilized when neither direct repair nor grafting is possible, often involving re-routing intact regional nerves to restore function. Nerve conduits play a pivotal role in nerve regeneration by bridging nerve gaps, with significant advancements made in material composition and design. Emerging trends in nerve regeneration include the use of 3D bioprinting for personalized conduits, gene therapy for targeted growth factor delivery, and nanotechnology for nanofiber-based conduits and stem cell therapy. Advancements in molecular sciences have provided critical insights into the cellular and biochemical mechanisms underlying nerve repair, leading to targeted therapies that enhance axonal regeneration, remyelination, and functional recovery in peripheral nerve injuries. This review explores the current strategies for the therapeutic management of peripheral nerve injuries, highlighting their indications, benefits, and limitations, while emphasizing the need for tailored approaches based on injury severity and patient factors.

Pediatr Cardiol 2025:10.1007/s00246-025-03863-z. [PMID: 40244319 DOI: 10.1007/s00246-025-03863-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2025] [Accepted: 04/10/2025] [Indexed: 04/18/2025]
Abstract
To investigate the correlation between prognostic nutritional index (PNI) and vasovagal syncope (VVS) in children, as well as its predictive value. 151 children (68 males, aged 4-18 years) diagnosed with VVS due to unexplained syncope and presyncope in our hospital from January 2022 to December 2023 were the study group, 152 healthy children (72 males, aged 7-14 years) who underwent physical examination in the same hospital during the same period of time were matched as the control group. Serum albumin (SA), serum globulin (SG), albumin/globulin (AGR), and peripheral blood lymphocyte absolute count (Lc) were measured, and PNI was calculated. ①PNI (51.35 vs. 55.28), SA (40.90 g/L vs. 43.05 g/L), AGR (1.65 vs. 1.75), and Lc (2.08 × 109/L vs. 2.49 × 109/L) were decreased in VVS group compared with control group (P < 0.05). ②Predictive analysis of VVS by PNI: The area under receiver operator characteristic curve of PNI prediction of VVS was 0.814, which indicated that PNI had moderate predictive value for VVS diagnosis. When PNI cutoff value was 55.00, the sensitivity, specificity, and Youden index of predicting VVS were 90.73%, 54.61%, and 0.45, respectively. ③PNI (OR = 0.65, 95%CI: 0.58-0.74, P < 0.001) is also as an independent protective factor for VVS. PNI is correlated with VVS in children, holds predictive value for the diagnosis of pediatric VVS, and serves as an independent protective factor for VVS occurrence in children.

Abstract
Wernicke's encephalopathy (WE) is an acute or subacute neuropsychiatric condition associated with thiamine deficiency that is more often seen in cases of alcohol abuse. The current study presents a rare case of primary cervical cancer complicated by WE. A 44-year-old woman who underwent a laparoscopic radical hysterectomy with endoscopic pelvic lymphadenectomy for primary cervical adenocarcinoma in 2014 developed multiple metastases in the pelvic and abdominal cavities, right iliopsoas muscle and iliac wing 2 years post-surgery. The patient was hospitalized due to the rupture of a mass in the right lower abdomen in August 2019. A computed tomography scan demonstrated the spreading of primary cervical cancer to the right lower abdomen, which broke through the skin. In this terminal stage of cervical cancer accompanied with malnutrition, the patient suddenly presented with cognitive impairment, particularly in recent and immediate memory, as well as bilateral sustained nystagmus during hospitalization. Brain magnetic resonance imaging showed hyperintensity in the periaqueductal midbrain on T2 fluid-attenuated inversion recovery imaging. Based on these findings, a diagnosis of WE was made, and thiamine (100 mg) was immediately administered intramuscularly three times a day. After a week, the patient's eye movement disorder and recent memory improved gradually. The present case report with literature review aims to demonstrate the significant comorbidity between cancer and WE, raising awareness about the importance of recognizing the risk of thiamine deficiency in advanced cancer to prevent the development of WE.

Vitamin D, B9, and B12 Deficiencies as Key Drivers of Clinical Severity and Metabolic Comorbidities in Major Psychiatric Disorders. Nutrients 2025; 17:1167. [PMID: 40218925 PMCID: PMC11990871 DOI: 10.3390/nu17071167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2025] [Revised: 03/21/2025] [Accepted: 03/25/2025] [Indexed: 04/14/2025] Open
Abstract
Background/Objectives: Severe mental illnesses such as schizophrenia, major depressive disorder, and bipolar disorder are often accompanied by metabolic comorbidities. While the role of vitamins in physical health is well-established, their involvement in psychiatric disorders has garnered increasing attention in recent years. Methods: We conducted a cross-sectional analysis of 1003 patients diagnosed with severe mental illnesses. Vitamin D, B9, and B12 serum levels were measured, and deficiencies were defined using established clinical cutoffs. Multivariate regression analyses were performed to identify associations between vitamin deficiencies and clinical outcomes. Results: Our findings revealed that vitamin deficiencies were prevalent across all diagnostic groups, with particularly high rates in patients with schizophrenia and major depressive disorder. Vitamin D deficiency was significantly associated with worse psychiatric outcomes, including increased depressive symptoms (adjusted OR = 1.89, p = 0.018), lower Global Assessment of Functioning scores (adjusted OR = -0.18, p < 0.001), and higher rates of metabolic syndrome (adjusted OR = 1.97, p = 0.007). Folate and B12 deficiencies were also linked to greater psychiatric symptom severity and metabolic disturbances, including increased risks of obesity and dyslipidemia. Conclusions: Our study highlights the critical role of vitamins deficiencies in both psychiatric and metabolic health of patients with severe mental illnesses. These findings underscore the importance of routine screening and correction of these deficiencies as part of comprehensive care in psychiatric populations. The integration of nutritional interventions may offer a novel and holistic approach to improving both mental and physical health outcomes.

Abstract
Peripheral neuropathy (PN) is a prevalent condition characterized by damage to peripheral nerves, often linked to risk factors such as diabetes. This condition results from various forms of neural damage, including injury to the cell body, axons, or demyelination, frequently beginning with small and thinly or unmyelinated fibers. Such nerve damage disrupts normal signaling, leading to symptoms like numbness, tingling, and pain. Effective nerve repair and regeneration, particularly through remyelination, are essential therapeutic objectives. While vitamin B12's role in repair processes has been well established, emerging evidence suggests that other neurotropic vitamins, specifically B1 and B6, also contribute significantly to nerve health and symptom relief in PN. In this study, we demonstrate that a combination treatment of vitamins B1, B6, and B12 enhances repair and oxidative stress responses in co-cultures of neural and Schwann cells, leading to improved cell maturation and connectivity compared to vitamin B12 alone. Furthermore, proteomic analysis supports these observations at the molecular level, with enhanced cellular recycling processes like proteasome enhancement, as well as protein synthesis upregulation, needed to rebuild nerve connections and combatting oxidative stress. Our combined morphological and molecular results highlight the potential therapeutic advantage of the B1, B6, and B12 combination over vitamin B12 alone.

Jang K. An Observational Study on the Association Between Nutritional Intake and Mental Health Among Older Adults in Rural Areas. Nurs Health Sci 2025; 27:e70080. [PMID: 40101703 PMCID: PMC11919469 DOI: 10.1111/nhs.70080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2024] [Revised: 03/01/2025] [Accepted: 03/07/2025] [Indexed: 03/20/2025]
Abstract
This study examined the relationship between nutritional intake and mental health, focusing on depressive symptoms among older adults in rural areas. Using data from the 2022 Korea National Health and Nutrition Examination Survey (KNHANES), the nutritional intake of 465 individuals aged 65 and older was analyzed against recommended nutrient intakes (RNI). Mental health was assessed using the PHQ-9 and GAD-7 scales, with logistic regression identifying predictors of depressive symptoms. Results showed deficiencies in essential vitamins, including A, B3 (niacin), C, D, and E. Higher intakes of niacin (≥ 5 mg/day) and Vitamin E (≥ 5 mg α-TE/day) were associated with reduced depressive symptoms. Energy, protein, and fiber intake also negatively correlated with depressive symptoms, emphasizing the importance of overall nutritional balance. Interestingly, Vitamin C intake was positively associated with anxiety symptoms, suggesting complex diet -mental health interactions. Implications for clinical practice highlight the importance of integrated nutritional screening and mental health interventions, particularly in underserved rural communities. However, given the observational nature of this study, further research is recommended to establish causality and explore the effectiveness of targeted supplementation programs.

Ahmed HS, Thrishulamurthy CJ. Vincristine-induced ptosis in pediatric patients: a systematic review and practice recommendations. Eur J Pediatr 2025; 184:209. [PMID: 39994116 DOI: 10.1007/s00431-025-06039-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2024] [Revised: 12/30/2024] [Accepted: 02/12/2025] [Indexed: 02/26/2025]
Abstract
Vincristine, a chemotherapy drug primarily used in pediatric cancer treatments like acute lymphoblastic leukemia and Wilms' tumor, is known for neurotoxic side effects, including a rare but under-discussed manifestation-vincristine-induced ptosis. This systematic review (PROSPERO: CRD42024617946) analyzed data from three databases, identifying 379 articles. Of these, 28 articles encompassing 31 unique pediatric cases were included, with Turkey contributing the highest number of cases (9 cases, 29.03%). The median age was 3 years (IQR: 2 - 5.5), with 58.06% male (18 cases) and 41.93% female (13 cases). Ptosis appeared bilaterally in 61.29% (19 cases) and unilaterally in 38.71% (12 cases), showing a left-side predominance in unilateral cases. The median time to symptom onset after the last vincristine dose was 6 days (IQR: 2 - 12). Treatment protocols varied; 74.19% (23 cases) adjusted or discontinued vincristine, with 34.78% (8 cases) restarting after skipping doses. Pyridoxine with or without pyridostigmine was used in 70% (14 of 20 treated cases), and recovery was generally favorable, with symptoms resolving within 28 days (IQR: 22.75 - 42) in most cases. Mild residual ptosis was noted in 9.67% (3 cases). Our review shows the significant variability inherent to management approaches in this patient demographic and highlights the need for standardized documentation and treatment approaches, proposing "VINTOSIS-3" as a practical treatment protocol. Furthermore, the VICTORIA (Vincristine-InduCed pTOsis cRIteriA) Grading is introduced to standardize ptosis severity evaluation. We further emphasize the importance of early detection, vigilant monitoring, and tailored interventions to balance neurotoxicity management with chemotherapy efficacy. What is Known: • Vincristine, a widely used chemotherapeutic agent in pediatric oncology, is associated with toxic side effects, primarily peripheral neuropathy. • Ocular complications of vincristine, including ptosis, have been reported but remain under-recognized. What is New: • Vincristine-induced ptosis is predominantly bilateral, but when unilateral, it shows a left-sided predominance and typically appears after a median of four doses. • The proposed VICTORIA Grading standardizes severity assessment, and the VINTOSIS-3 protocol provides a structured approach to management.

Abstract
Alzheimer's disease (AD), the most common form of dementia, is a progressive neurodegenerative disorder that profoundly impacts cognitive function and the nervous system. Emerging evidence highlights the pivotal roles of iron homeostasis dysregulation and microbial inflammatory factors in the oral and gut microbiome as potential contributors to the pathogenesis of AD. Iron homeostasis disruption can result in excessive intracellular iron accumulation, promoting the generation of reactive oxygen species (ROS) and oxidative damage. Additionally, inflammatory agents produced by pathogenic bacteria may enter the body via two primary pathways: directly through the gut or indirectly via the oral cavity, entering the bloodstream and reaching the brain. This infiltration disrupts cellular homeostasis, induces neuroinflammation, and exacerbates AD-related pathology. Addressing these mechanisms through personalized treatment strategies that target the underlying causes of AD could play a critical role in preventing its onset and progression.

Pharmaceutics 2025; 17:73. [PMID: 39861721 PMCID: PMC11769253 DOI: 10.3390/pharmaceutics17010073] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2024] [Revised: 12/30/2024] [Accepted: 01/02/2025] [Indexed: 01/27/2025] Open
Abstract
Background/Objectives: Retinal ganglion cell (RGC) protection represents an unmet need in glaucoma. This study assessed the neuroprotective, antioxidant, and anti-inflammatory effect of a new nutraceutical formulation named Epicolin, based on citicoline, homotaurine, epigallocatechin-3-gallate, forskolin, and vitamins, through in vitro and in vivo studies. Methods: The neuroprotective effect of Epicolin or its single components, and Epicolin compared to an untreated control and two marketed formulations [Formulation G (FG) and N (FN)], was evaluated in neuroblastoma cells (SH-SY5Y) challenged with staurosporine. The antioxidant potential and the scavenging activity of Epicolin compared to the untreated control, and FG and FN, was evaluated in SH-SY5Y cells and through oxygen radical absorbance capacity acellular assay, respectively. Moreover, the protective effect against hypoxic damage was evaluated in Muller cells (MIO-M1) subjected to hypoxia. The efficacy of Epicolin was also evaluated in DBA/2J glaucomatous mice through the use of a pattern electroretinogram (PERG), immunostaining, and real-time PCR. Results: Among the nutraceutical formulations tested, only Epicolin showed a significant neuroprotective effect on SH-SY5Y attributable to the synergistic action of its single ingredients. As for antioxidant and scavenging activity, Epicolin showed a higher efficacy compared to FG and FN. Furthermore, Epicolin showed the same protective effect on MIO-M1 cells reducing HIF-1α expression. Finally, Epicolin treatment on DBA/2J mice protected the RGCs from loss of function, as demonstrated by PERG analysis, and attenuated their death by enhancing brain-derived neurotrophic factor (BDNF) and reducing interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) expression. Conclusions: Epicolin, due to its neuroprotective, antioxidant, and anti-inflammatory properties, represents a promising potential treatment for glaucoma.

Abstract
Neuropathies, which encompass a wide array of peripheral nervous system disorders, present significant challenges due to their varied causes, such as metabolic diseases, toxic exposures, and genetic mutations. This review article, focused on the critical role of neurotrophins in peripheral neuropathy, highlights the intricate balance of neurotrophins necessary for nerve health and the pathophysiological consequences when this balance is disturbed. Neurotrophins, including Nerve Growth Factor (NGF), Brain-Derived Neurotrophic Factor (BDNF), Neurotrophin-3 (NT- 3), and Neurotrophin-4 (NT-4), are essential for neuronal survival, axonal growth, and synaptic plasticity. Their signaling pathways are crucial for maintaining peripheral nervous system integrity, primarily via the Tropomyosin receptor kinase (Trk) receptors and the p75 neurotrophin receptor p75(NTR). Dysregulation of neurotrophins is implicated in various neuropathies, such as diabetic neuropathy and chemotherapy-induced peripheral neuropathy, leading to impaired nerve function and regeneration. Understanding neurotrophin signaling intricacies and their alterations in neuropathic conditions is crucial for identifying novel therapeutic targets. Recent advancements illuminate neurotrophins' potential as therapeutic agents, promising disease-modifying treatments by promoting neuronal survival, enhancing axonal regeneration, and improving functional recovery post-nerve injury. However, translating these molecular insights into effective clinical applications faces challenges, including delivery methods, target specificity, and the instability of protein- based therapies.

Neuropharmacology 2024; 261:110169.

Abstract
Peripheral nerve injury (PNI), typically caused by traumatic accidents or medical events, is currently one of the most common diseases that leads to limb disability. After PNI, tetrodotoxin-resistant voltage-gated sodium channel Nav1.8 is upregulated at the lesion site. Our earlier study suggested that ropivacaine promotes axon regrowth by regulating Nav1.8-mediated macrophage signaling. Nevertheless, the mechanism of ropivacaine in regulation of Nav1.8 expression remains incompletely understood. Kinesin family 5b (KIF5b) was reported to mediate the Nav1.8 axonal transport from dorsal root ganglia (DRGs) to lesion site. Herein, we investigated whether ropivacaine promotes axon regeneration through inhibition of KIF5b-mediated Nav1.8 transport. Reduced levels of KIF5b and Nav1.8 in DRGs coincide with their increase at the lesion site. Nav1.8 mRNA was significantly increased at the lesion site but not in DRGs. Surprisingly, ropivacaine reversed the alterations of Nav1.8 and KIF5b protein expression without affecting Nav1.8 mRNA level. Due to KIF5b overexpression in DRGs, Nav1.8 protein level was significantly decreased in DRGs and increased at the lesion site. We also found KIF5b overexpression significantly impaired behavioral functions, reduced the recovery index of compound muscle action potential (CMAP) amplitude, inhibited axonal regrowth, slowed M1 macrophage infiltration and shift to M2 phenotype, and delayed myelin debris clearance. Notably, all aforementioned results caused by KIF5b overexpression were alleviated by ropivacaine. Furthermore, we demonstrated that inhibition of Nav1.8 transport by A-803467 produced mitigating effects on the impairment of regenerative capacity induced by KIF5b overexpression similar to ropivacaine. These results suggest that ropivacaine promotes axonal regeneration at least partially by inhibiting KIF5b-mediated Nav1.8 forward transport.

Abstract
Background/Objectives: Radiculopathy leads to pain, consequently reducing patient's quality of life (QoL). Research indicates that certain nucleotides, such as cytidine and uridine, along with vitamins B1 and B12, may help alleviate pain and enhance QoL. This study assessed the impact of adding a supplement containing cytidine and uridine nucleotides and vitamins B1 and B12, alongside standard treatment, on radiculopathy-associated pain. Methods: A multicenter, prospective, two-cohort, randomized, open-label study was conducted. The control group received standard treatment, while the experimental group received standard treatment plus the supplement. The primary endpoint was pain reduction measured by a Visual Analog Scale (VAS). Secondary endpoints included functional improvement (Roland Morris questionnaire), clinical improvement (Clinical Global Impression [CGI] scale), and QoL improvement (EQ-5D-5L questionnaire). Results: A total of 122 patients were included from 17 centers across Spain. Both groups showed pain improvement, but the VAS reduction (control: 24.58 vs. experimental: 31.35) was not statistically significant. The Roland Morris score decreased significantly in the experimental group (estimate: -1.70, 95% CI -3.29 to -0.10; p = 0.038), and these patients were 5 times more likely to progress to a better CGI category (OR = 0.20, 95% CI 0.07 to 0.57; p = 0.003). No significant differences were observed in EQ-5D-5L scores or analgesic consumption. Conclusions: The addition of supplemental pyrimidine nucleotides and vitamins B1 and B12 to standard of care treatment improved radiculopathy functional and clinical outcomes. Regarding pain, however, although there was a numerical improvement, it did not reach statistical significance.

Abstract
Background/Objectives: Photobiomodulation therapy (PBM) creates a biostimulatory or modulatory effect, promoting tissue regeneration and improving patients' health-related quality of life (HRQoL). PBM has shown promise as an effective treatment and management strategy for peripheral nerve injuries, including inferior alveolar nerve (IAN) damage. This study aims to assess the impact of PBM on HRQoL in patients with iatrogenic IAN injuries. Methods: A prospective study was implemented to investigate the research question. PBM treatments were administered weekly, with patient discharge contingent upon either complete recovery or stabilization of associated signs and symptoms. HRQoL was assessed using the EQ-5D-5L questionnaire at the initial and final appointments. Results: The study included 71 participants, divided into 3 groups based on etiology: inferior third molar surgery, mandibular orthognathic surgery, and dental implant surgery. The results showed a widespread reduction of symptoms along with a statistically significant improvement (p < 0.001) across four of the five dimensions of the EQ-5D-5L questionnaire, as well as in patients' perceived health levels in both Groups I and II. Group III patients also demonstrated a notable improvement; however, due to the small sample size, statistical analysis was not conducted for this group. Conclusions: PBM demonstrated a comparable ability to enhance HRQoL and alleviate symptoms in patients with IAN injuries within different etiologies. These findings underscore the effectiveness of the protocol used in this study and highlight potential avenues for expanding research in this field.

Abstract
Alzheimer's disease (AD) remains one of the most debilitating disease and most common neurological disorder in the world at large. However, with many years of multiple research and billions of dollars invested for the purpose of research, not many therapeutic options exist for the management of this disease. As at 2023, the number has only increased to 7, one of which is a combination of two existing therapies. However, research has continued still in the search for a cure. The roles and functions of thiamine, pyridoxine and cobalamin in the proper function of the nervous system has been well researched over time and their role in the management of neurological diseases have been of interest in the last decade. This review describes the roles of the aforementioned chemicals in the management of different models of AD and AD-like pathologies as mono-therapeutic agents and prospective adjuvant for combination therapy.

PURPOSE Optic neuritis is the most common optic neuropathy affecting adults, especially women. Lactational optic neuritis is a rare entity occurring during the postpartum period with a high chance of recurrence. Through this study, we evaluated the clinical profile and visual outcome of lactational optic neuritis. METHODS This was a retrospective study where patients with optic neuritis presenting during the first year of the postpartum period to the neuro-ophthalmology clinic between January 2016 and December 2022 were included in the study. RESULTS This study included seven eyes of six patients. The mean age of presentation was 24.6 years, with all patients presenting after the first 3 months of the postpartum period. All patients had unilateral involvement except one, presenting with painful vision loss. Best corrected visual acuity ranged from 6/18 to hand movements. Relative afferent pupillary defect and dyschromatopsia were present in all patients. Disc edema was seen in all but one case. Three patients were treated with steroids along with multivitamins, and the remaining three refused treatment with steroids, receiving multivitamins alone. All patients had complete recovery by the end of 12 weeks. CONCLUSION Optic neuritis during lactation is attributed more to post-pregnancy immunological changes rather than lactation itself. The presentation and clinical features are similar to classic optic neuritis and remain an important differential diagnosis for visual dysfunction in the postpartum period.

Abstract
BACKGROUND Numerous studies reported a higher prevalence of polyneuropathy (PNP) in patients with Parkinson's disease (PD) compared to the general population. Importantly, PNP symptoms can aggravate both motor and sensory disturbances in PD patients and negatively impact the disease course. Recent analyses indicate distinct PNP patterns in PD. MAIN TEXT This review aims to provide an overview of the current insights into etiological factors, diagnostic methods, and management strategies of large fiber neuropathy in PD. Despite the higher prevalence, the causes of PNP in PD are still not fully understood. A genetic predisposition can underlie PNP onset in PD. Main research attention is focused on long-term levodopa exposure which is suggested to increase PNP risk by depletion of methylation cofactors such as vitamin B12 and accumulation of homocysteine that altogether can alter peripheral nerve homeostasis. Beyond a potential "iatrogenic" cause, alpha-synuclein deposition has been detected in sural nerve fibers that could contribute to peripheral neuronal degeneration as part of the systemic manifestation of PD. Whereas mild axonal sensory PNP predominates in PD, a considerable proportion of patients also show motor and upper limb nerve involvement. Intriguingly, a correlation between PNP severity and PD severity has been demonstrated. Therefore, PNP screening involving clinical and instrument-based assessments should be implemented in the clinical routine for early detection and monitoring. Given the etiological uncertainty, therapeutic or preventive options remain limited. Vitamin supplementation and use of catechol-O-methyltransferase-inhibitors can be taken into consideration. CONCLUSION PNP is increasingly recognized as a complicating comorbidity of PD patients. Long-term, large-scale prospective studies are required to elucidate the causative factors for the development and progression of PD-associated PNP to optimize treatment approaches. The overall systemic role of "idiopathic" PNP in PD and a putative association with the progression of neurodegeneration should also be investigated further.

Abstract
Background The causal relationship between familial hypercholesterolemia (FH) and various vitamin deficiencies has not yet been elucidated. Therefore, this study investigated the cause-and-effect relationship between FH and the risk of multiple vitamin deficiencies in humans. Methods Mendelian randomization (MR) analysis was performed by extracting six datasets for FH, FH with ischemic heart disease (IHD), and vitamin deficiency (vitamin A, thiamine, other B-group vitamins, and vitamin D) from the FinnGen study, covering a total of 329,115; 316,290; 354,932; 354,949; 355,411 and 355,238 individuals, respectively. Results FH was suggestively associated with higher odds of thiamine deficiency [inverse variance weighted odds ratio (ORIVW) 95% confidence interval (CI): 1.62 (1.03, 2.55), P = 0.036] and vitamin D deficiencies [ORIVW CI: 1.35 (1.04, 1.75), P = 0.024], low-density lipoprotein receptor (LDLR) rs112898275 variant, rs11591147 and rs499883 in proprotein convertase subtilisin/kexin 9 (PCSK9), rs9644862 in cyclin-dependent kinase inhibitor 2 B antisense RNA1 (CDKN2B-AS1), and rs142834163 in dedicator of cytokinesis 6 (DOCK6) and rs115478735 in ABO blood group (ABO) strongly influenced the risk of thiamine deficiency, while the rs7412 variant in apolipoprotein E (APOE) mostly influenced the risk of vitamin D deficiency. FH with IHD was suggestively associated with higher odds of vitamin D deficiency (ORIVW, weighted median [WM][95%CI]: 1.31 [1.05, 1.64]; 1.47 [1.10, 1.97]) (P = 0.018; 0.010) without any single significant SNPs observed. Conclusion FH was positively associated with increased risks of thiamine and vitamin D deficiencies, revealing a prospective and unfortunate complication of FH.

Abstract
Neuropathic pain, a debilitating condition, remains challenging to manage effectively. An insight into neuropharmacological mechanisms is critical for optimizing treatment strategies. This systematic review aims to evaluate the role of neuropharmacological agents based on their efficacy, involved neurotransmitters, and receptors. A manual literature search was undertaken in PubMed including Medline, Cochrane Library, Google Scholar, Plos One, Science Direct, and clinicaltrials.gov from 2013 until 2023. Out of the 13 included studies, seven evaluated the role of gabapentinoids. Two main drugs from this group, gabapentin and pregabalin, function by binding voltage-gated calcium channels, lowering neuronal hyperexcitability and pain signal transmission, thereby relieving neuropathic pain. Four of the pooled studies reported the use of tricyclic antidepressants (TCAs) including amitriptyline and nortriptyline which work by blocking the reuptake of norepinephrine and serotonin, their increased concentration is thought to be central to their analgesic effect. Three articles assessed the use of serotonin-norepinephrine reuptake inhibitors (SNRIs) and reported them as effective as the TCAs in managing neuropathic pain. They work by augmenting serotonin and norepinephrine. Three studies focused on the use of selective serotonin reuptake inhibitors (SSRIs), modulating their effect by increasing serotonin levels; however, they were reported as not a highly effective treatment option for neuropathic pain. One of the studies outlined the use of cannabinoids for neuropathic pain by binding to cannabinoid receptors with only mild adverse effects. It is concluded that gabapentinoids, TCAs, and SNRIs were reported as the most effective therapy for neuropathic pain; however, for trigeminal neuralgia, anticonvulsants like carbamazepine were considered the most effective. Opioids were considered second-line drugs for neuropathic pain as they come with adverse effects and a risk of dependence. Ongoing research is exploring novel drugs like ion channels and agents modulating pain pathways for neuropathic pain management. Our review hopes to inspire further research into patient stratification by their physiology, aiding quicker and more accurate management of neuropathic pain while minimizing inadvertent side effects.

Abstract
Background While deficiencies in vitamin B6, folate, and vitamin B12 are linked to various human diseases, including anemia, depression, peripheral neuropathy, and cardiovascular disease (CVD), literature regarding the association between vitamin B6, folate, and vitamin B12 and erectile dysfunction (ED) is scarce. We aimed to determine the dietary intake of vitamin B6, folate, and vitamin B12 and ED in the United States population. Methods We extracted data from the 2001-2004 cycles of the National Health and Nutrition Examination Survey (NHANES). Dietary intakes of B vitamins were collected based on one 24-hour dietary recall. The association between dietary intake of vitamin B6, folate, vitamin B12 and ED was examined using multivariate logistic regression models. Results A total of 3,875 participants were included for analysis, with 1,201 reporting ED and 2,894 not experiencing ED. The multivariable odds ratios (ORs) for the highest vs. lowest quartiles of vitamin B6 was 0.77 [95% confidence interval (CI): 0.60-0.99; P for trend =0.03] for the prevalence of ED. Subgroup analyses demonstrated a significant inverse association between dietary intake of vitamin B6, folate, vitamin B12 and the prevalence of ED among men aged ≤60 years, individuals of Mexican American and non-Hispanic White ethnicity, and those without a history of CVD, diabetes, hypertension, and high cholesterol. Conclusions The consumption of dietary vitamin B6, folate, and vitamin B12 was significantly linked to decreased risks of ED among younger healthier men, suggesting a potential protective role of these nutrients against ED in United States adults.

Vitamin B6 status and chronic chemotherapy-induced peripheral neuropathy: a prospective cohort study among patients with non-metastatic colorectal cancer receiving oxaliplatin-based chemotherapy. BMJ ONCOLOGY 2024; 3:e000462.

Abstract
Objective Chronic chemotherapy-induced peripheral neuropathy (CIPN) is a long-lasting side-effect of oxaliplatin. Vitamin B6 might play a role in the pathogenesis of CIPN. Therefore, we investigated associations between plasma vitamin B6 markers and the occurrence and severity of chronic CIPN in patients with non-metastatic colorectal cancer (CRC). Methods and analysis 242 patients with CRC receiving oxaliplatin-based chemotherapy were included. Blood samples were collected at diagnosis (ie, before chemotherapy), and 6 and 12 months after diagnosis (ie, during and after chemotherapy, respectively). Pyridoxal 5'-phosphate (PLP), pyridoxal (PL) and xanthurenic acid:3-hydroxykynurenine (XA:HK) ratio were measured as vitamin B6 markers using liquid chromatography tandem mass spectrometry. Chronic CIPN was assessed 12 months after diagnosis using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-CIPN twenty-item scale questionnaire. Prevalence ratios (PRs) and restricted cubic splines (RCSs) were used to assess associations with chronic CIPN occurrence, and linear regressions were used to assess associations with chronic CIPN severity. Analyses were adjusted for age, sex, smoking, alcohol consumption, diabetes and timing of chemotherapy (neoadjuvant/adjuvant/both). Results Chronic CIPN was found in 80% (n=194) of patients. Higher PLP levels and XA:HK ratios during chemotherapy were associated with lower occurrence of chronic CIPN (PRperdoubling 0.75, 95% CI 0.62 to 0.91 and PRCS<0.05, respectively) and lower chronic CIPN severity (βperdoubling -4.54, 95% CI -7.12 to -1.96 and βperdoubling -6.30, 95% CI -9.53 to -3.07, respectively). No associations between PL levels and chronic CIPN were observed. Conclusion Within this population, merely having PLP levels within the normal range, higher vitamin B6 status during chemotherapy was associated with lower occurrence and severity of chronic CIPN. Future research is warranted to investigate causality and the optimal vitamin B6 status during chemotherapy.

Abstract
Traumatic brain injury is a major cause of death and disability worldwide, affecting over 69 million individuals yearly. One-carbon metabolism has been shown to have beneficial effects after brain damage, such as ischemic stroke. However, whether increasing one-carbon metabolite vitamins impacts traumatic brain injury outcomes in patients requires more investigation. The aim of this review is to evaluate how one-carbon metabolites impact outcomes after the onset of traumatic brain injury. PubMed, Web of Science, and Google Scholar databases were searched for studies that examined the impact of B-vitamin supplementation on traumatic brain injury outcomes. The search terms included combinations of the following words: traumatic brain injury, dietary supplementation, one-carbon metabolism, and B-vitamins. The focus of each literature search was basic science data. The year of publication in the literature searches was not limited. Our analysis of the literature has shown that dietary supplementation of B-vitamins has significantly improved the functional and behavioral recovery of animals with traumatic brain injury compared to controls. However, this improvement is dosage-dependent and is contingent upon the onset of supplementation and whether there is a sustained or continuous delivery of vitamin supplementation post-traumatic brain injury. The details of supplementation post-traumatic brain injury need to be further investigated. Overall, we conclude that B-vitamin supplementation improves behavioral outcomes and reduces cognitive impairment post-traumatic brain injury in animal model systems. Further investigation in a clinical setting should be strongly considered in conjunction with current medical treatments for traumatic brain injury-affected individuals.

Abstract
(1) Background: To investigate the risk factors associated with optic neuropathy (ON) and validate the hypothesis that concomitant isoniazid use and other causes of toxic ON affect the development of ON in ethambutol users. (2) Methods: This cohort study identified ethambutol users who initiated ethambutol therapy between January 2015 and December 2021 and had no ON prior to ethambutol therapy. ON incidence up to 31 December 2022 was evaluated. The users were grouped on the basis of the presence of ON. Demographic and clinical characteristics were investigated for risk factor analyses of ON. Odds ratios (ORs) were calculated using multivariate logistic regression analyses. (3) Results: Among 204,598 ethambutol users, 5277 (2.6%) patients developed ON over the study period. Patients with ON included a higher percentage of women and had a higher mean age than patients without ON. In the multivariate analyses, the risk factors for ON and visual impairment included sex, age, cumulative dose, extrapulmonary indications for ethambutol use, and systemic conditions such as diabetes, hypertension, hyperlipidemia, diabetes, kidney disease, and liver disease. Malnutrition or nutritional disorders significantly increased the risk of ON (OR = 1.27, 95% confidence interval [CI] = 1.19-1.34), whereas concomitant isoniazid use decreased the risk (OR = 0.78, 95% CI = 0.72-0.86). (4) Conclusion: An increased risk of ON in patients with systemic diseases and nutritional deficiency was identified, whereas concomitant isoniazid use was associated with a decreased risk of ON. Patients with these risk factors should be carefully monitored to minimize the vision-threatening ON.

Abstract
Multiple organs and tissues coordinate to respond to dietary and environmental challenges. It is interorgan crosstalk that contributes to systemic metabolic homeostasis. The liver and brain, as key metabolic organs, have their unique dialogue to transmit metabolic messages. The interconnected pathogenesis of liver and brain is implicated in numerous metabolic and neurodegenerative disorders. Recent insights have positioned the liver not only as a central metabolic hub but also as an endocrine organ, capable of secreting hepatokines that transmit metabolic signals throughout the body via the bloodstream. Metabolites from the liver or gut microbiota also facilitate a complex dialogue between liver and brain. In parallel to humoral factors, the neural pathways, particularly the hypothalamic nuclei and autonomic nervous system, are pivotal in modulating the bilateral metabolic interplay between the cerebral and hepatic compartments. The term "liver-brain axis" vividly portrays this interaction. At the end of this review, we summarize cutting-edge technical advancements that have enabled the observation and manipulation of these signals, including genetic engineering, molecular tracing, and delivery technologies. These innovations are paving the way for a deeper understanding of the liver-brain axis and its role in metabolic homeostasis.

Abstract
Charcot-Marie-Tooth (CMT) neuropathy is a polygenic disorder of peripheral nerves with no effective cure. Thiamine (vitamin B1) is a neurotropic compound that improves neuropathies. Our pilot study characterizes therapeutic potential of daily oral administration of thiamine (100 mg) in CMT neuropathy and its molecular mechanisms. The patient hand grip strength was determined before and after thiamine administration along with the blood levels of the thiamine coenzyme form (thiamine diphosphate, ThDP), activities of endogenous holo-transketolase (without ThDP in the assay medium) and total transketolase (with ThDP in the assay medium), and transketolase activation by ThDP [1 - (holo-transketolase/total transketolase),%], corresponding to the fraction of ThDP-free apo-transketolase. Single cases of administration of sulbutiamine (200 mg) or benfotiamine (150 mg) reveal their effects on the assayed parameters within those of thiamine. Administration of thiamine or its pharmacological forms increased the hand grip strength in the CMT patients. Comparison of the thiamin status in patients with different forms of CMT disease to that of control subjects without diagnosed pathologies revealed no significant differences in the average levels of ThDP, holo-transketolase, or relative content of holo and apo forms of transketolase. However, the regulation of transketolase by thiamine/ThDP differed in the control and CMT groups: in the assay, ThDP activated transketolase from the control individuals, but not from CMT patients. Thiamine administration paradoxically decreased endogenous holo-transketolase in CMT patients; this effect was not observed in the control group. Correlation analysis revealed sex-specific differences in the relationship between the parameters of thiamine status in both the control subjects and patients with the CMT disease. Thus, our findings link physiological benefits of thiamine administration in CMT patients to changes in their thiamine status, in particular, the blood levels of ThDP and transketolase regulation.

[PMID: 38928831 PMCID: PMC11203375 DOI: 10.3390/foods13121890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Revised: 06/11/2024] [Accepted: 06/14/2024] [Indexed: 06/28/2024] Open
Abstract
Metals are integral components of the natural environment, and their presence in the food supply is inevitable and complex. While essential metals such as sodium, potassium, magnesium, calcium, iron, zinc, and copper are crucial for various physiological functions and must be consumed through the diet, others, like lead, mercury, and cadmium, are toxic even at low concentrations and pose serious health risks. This study comprehensively analyzes the presence, importance, and consequences of metals in the food chain. We explore the pathways through which metals enter the food supply, their distribution across different food types, and the associated health implications. By examining current regulatory standards for maximum allowable levels of various metals, we highlight the importance of ensuring food safety and protecting public health. Furthermore, this research underscores the need for continuous monitoring and management of metal content in food, especially as global agricultural and food production practices evolve. Our findings aim to inform dietary recommendations, food fortification strategies, and regulatory policies, ultimately contributing to safer and more nutritionally balanced diets.

Abstract
Objective Long-term alcohol consumption can cause organic damage to the brain, resulting in mental and nervous system abnormalities and intellectual impairment. Huanglian Jiedu decoction (HLJDD) is the classic representative of clearing heat and detoxifying. This study aimed to explore the effects and possible mechanisms of HLJDD on brain injury in chronic alcohol-exposed mice. Methods The alcohol-exposed mice were treated with different doses of HLJDD to observe behavioral changes, hippocampal Aβ1-42 deposition, number and ultrastructural changes of neurons in the hippocampus and prefrontal cortex, and expressions of synaptic proteins. On this basis, transcriptome sequencing was used to analyze the differentially expressed genes in different treatment groups, and functional enrichment analysis was performed. Then, WB and RT-PCR were used to verify the expression of the pathway. Results Chronic alcohol exposure reduced body weight in mice, led to motor cognitive impairment, increased Aβ1-42 in the hippocampus, decreased the number of neurons in the hippocampus and prefrontal cortex, and the expression of PSD95 and SYN in the hippocampus. HLJDD significantly improved the cognitive dysfunction of mice and alleviated the damage of the hippocampus and prefrontal cortex. Transcriptome sequencing results showed that the regulatory effects of HLJDD on chronic alcohol-exposed mice may be related to the RAS pathway. Further experiments confirmed that chronic alcohol exposure caused a significant increase in protein and gene expressions of the RAS-RAF-MEK-ERK pathway in mouse, and this activation was reversed by HLJDD. Conclusion HLJDD may ameliorate brain damage caused by chronic alcohol exposure by regulating the RAS-RAF-MEK-ERK pathway.

Abstract
Introduction Painful diabetic neuropathy (PDN) is a leading cause of pain and disability globally with a lack of consensus on the appropriate treatment of those suffering from this condition. Recent advancements in both pharmacotherapy and interventional approaches have broadened the treatment options for PDN. There exists a need for a comprehensive guideline for the safe and effective treatment of patients suffering from PDN. Objective The SWEET Guideline was developed to provide clinicians with the most comprehensive guideline for the safe and appropriate treatment of patients suffering from PDN. Methods The American Society of Pain and Neuroscience (ASPN) identified an educational need for a comprehensive clinical guideline to provide evidence-based recommendations for PDN. A multidisciplinary group of international experts developed the SWEET guideline. The world literature in English was searched using Medline, EMBASE, Cochrane CENTRAL, BioMed Central, Web of Science, Google Scholar, PubMed, Current Contents Connect, Meeting Abstracts, and Scopus to identify and compile the evidence for diabetic neuropathy pain treatments (per section as listed in the manuscript) for the treatment of pain. Manuscripts from 2000-present were included in the search process. Results After a comprehensive review and analysis of the available evidence, the ASPN SWEET guideline was able to rate the literature and provide therapy grades for most available treatments for PDN utilizing the United States Preventive Services Task Force criteria. Conclusion The ASPN SWEET Guideline represents the most comprehensive review of the available treatments for PDN and their appropriate and safe utilization.

Abstract
BACKGROUND Peripheral neuropathy is caused by a malfunction in the axons and myelin sheaths of peripheral nerves and motor and sensory neurons. In this context, nonpharmacological treatments with antioxidant potential have attracted much attention due to the issues that some conventional pharmaceutical therapy can generate. Most of these treatments contain lipoic acid, but issues have emerged regarding its use. Considering this, the present study evaluated the beneficial effects of nutraceuticals based on Gastrodiae elata dry extract 10:1 or lipoic acid in combination with other substances (such as citicholine, B vitamins, and acetyl L-carnitine). METHOD To assess the combination's absorption and biodistribution and exclude cytotoxicity, its bioavailability was first examined in a 3D intestinal barrier model that replicated oral ingestion. Subsequently, a 3D model of nerve tissue was constructed to investigate the impacts of the new combination on the significant pathways dysregulated in peripheral neuropathy. RESULTS Our findings show that the novel combination outperformed in initial pain relief response and in recovering the mechanism of nerve healing following Schwann cell injury by successfully crossing the gut barrier and reaching the target site. CONCLUSION This article describes a potential alternative nutraceutical approach supporting the effectiveness of combinations with Gastrodiae elata extract in decreasing neuropathy and regulating pain pathways.

Abstract
This consensus guidance is for community pharmacists in diabetic peripheral neuropathy (DPN) management with a combination of neurotropic B vitamins. A multidisciplinary team including endocrinology, neurology, and pharmacy from Thailand discussed and aligned the practical scheme of DPN management in the community pharmacy setting, using the literature review and having face-to-face meeting. Five major statements have been endorsed as consensus recommendations for DPN care with strong acknowledgment. The aims of DPN management included reducing symptoms and the risk of complications, minimising adverse reactions from treatment regimens, and improving patients' knowledge and adherence to the treatment strategies. An initial screening process using a 7 items interview of Douleur Neuropathique 4 (DN4) questionnaire should be implemented to identify patients at risk of developing DPN. Subsequently, pharmacologic, and non-pharmacologic treatment should be employed based on patient-centered care. An interesting approach is combination of neurotropic B vitamins, which may be used as monotherapy or combination therapy to control DPN symptoms. The combined therapy potentially exhibits a synergistic effect and improves patient adherence. The consensus would be further considered in context of harmonisation of routine practice and country requirements.

Abstract
Memory impairment during aging and amnesia is attributed to compromised mitochondrial dynamics and mitophagy and other mitochondrial quality control mechanisms. Mitochondrial dynamics involves the continuous process of fission and fusion of mitochondria within a cell and is a fundamental mechanism for regulating mitochondrial quality and function. An extensive range of potential nutritional supplements has been shown to improve mitochondrial health, synaptic plasticity, and cognitive functions. Previous findings revealed that supplementation of vitamin B12-folic acid reduces locomotor deficits and mitochondrial abnormalities but enhances mitochondrial and neuronal health. The present study aims to explore the impact of combined vitamin B12-folic acid supplementation on mitochondrial dynamics, neuronal health, and memory decline in old age and scopolamine-induced amnesia, which remains elusive. The results demonstrated that supplementation led to a noteworthy increase in recognition and spatial memory and expression of memory-related protein BDNF in old and amnesic mice. Moreover, the decrease in the fragmented mitochondrial number was validated by the downregulation of mitochondrial fission p-Drp1 (S616) protein and the increase in elongated mitochondria by the upregulation of mitochondrial fusion Mfn2 protein. The increased spine density and dendritic arborization in old and amnesic mice upon supplementation were confirmed by the enhanced expression level of PSD95 and synaptophysin. Furthermore, supplementation reduced ROS production, inhibited Caspase-3 activation, mitigated neurodegeneration, and enhanced mitochondrial membrane potential, ATP production, Vdac1 expression, myelination, in old and amnesic mice. Collectively, our findings imply that combined supplementation of vitamin B12-folic acid improves mitochondrial dynamics and neuronal health, and leads to recovery of memory during old age and amnesia.

Abstract
The importance of neurotropic vitamins in the prevention and adjuvant therapy of peripheral neuropathy - A pharmacist's comprehensive view Peripheral neuropathy is one of the most common neurological diseases of the peripheral nervous system. According to current statistics, it affects 2.4% of the Czech population, and its prevalence continues to increase with age. The possibilities of its treatment are to a large extent limited, and its effectiveness and the patient's tolerance of pharmacotherapy are individual. Neurotropic vitamins, which support the function of neurons and contribute to their protection and regeneration, represent a promising possibility for prevention and use in adjuvant therapy for patients suffering from this disease. Despite the fact that the diagnosis and treatment of peripheral neuropathy belong to the doctor, the role of the pharmacist can be crucial not only in the area of ensuring effective and safe pharmacotherapy and adherence to it, but also in pre-screening of at-risk persons visiting pharmacies. The primary aim of the article is therefore to familiarize readers with the significance of neurotropic vitamins in the prevention and adjunct therapy of peripheral neuropathy, as well as the role of the pharmacist in the care of patients suffering from this condition.

[PMID: 38146761 PMCID: PMC10750320 DOI: 10.2478/aiht-2023-74-3754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 07/01/2023] [Accepted: 12/01/2023] [Indexed: 12/27/2023] Open
Abstract
The contribution of certain occupational and personal factors to the development of carpal tunnel syndrome (CTS) is still uncertain. We investigated which specific occupational and non-occupational factors correlate with the level of clinical manifestations and work disability related to CTS. The study included 190 workers who work with a computer and have diagnosed CTS (100 men, 90 women, aged 20-65 years). Subjective experience of CTS-related impairments was assessed with the Symptom Severity Scale (SSS) and the Functional Status Scale (FSS) of the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ). The objective, neural impairments were tested with electrodiagnostics (EDX), whereas CTS-related work disability data were collected from medical records. We found a high inter-correlation between BCTQ, EDX, and work disability data. These also showed high correlations with certain occupational factors (duration of computer-working in months and hours spent daily in computer-working, certain ergonomic, microclimatic, and other occupational conditions) and non-occupational factors (demographic and lifestyle factors: nutritional status, diet, smoking, alcohol consumption, and physical activity). Despite its limitations, our study has identified occupational and non-occupational risk factors that can aggravate CTS and work disability, but which can also be improved with workplace and lifestyle preventive and corrective measures. More research is needed, though, to establish the possible causal relationships and the independent influence of each of those risk factors.

Abstract
Introduction B vitamins help generate energy within cells. A significant portion of populations in developed countries suffer a deficiency in one or more B vitamins. This study assesses the use of vitamin B supplements and their effects. Methodology This cross-sectional study was conducted using public participants in Saudi Arabia. Participants from all over Saudi Arabia were recruited through self-conducted surveys to study the effects of using vitamin B supplements on appetite, BMI, energy, and sleep, and to identify any side effects in participants. Inclusion criteria included age (18 years or older) and use of vitamin B supplements. Children, pregnant women, adults who had never used vitamin B, and those not willing to participate in the study were excluded. Results In total, 1,521 adults were recruited. Most of the participants were young Saudi Females. While taking vitamin B supplements, a minority of participants complained of mild gastrointestinal upset, but a significant proportion experienced no side effects. In this study, a significant proportion of participants experienced an increase in appetite, which was associated with a significant increase in BMI after taking vitamin B supplements. This study also explored increases in energy, which were significant and associated with significant increases in sleeping time. Male participants in the present study noticed a significant increase in erectile dysfunction (ED). Conclusions This study found significant effects of vitamin B supplements on BMI, appetite, energy, and sleep, as well as an increase in ED in male participants. More studies are needed to further explore these findings.

Abstract
COVID-19 Related Long-Term Taste Impairment (CRLTTI) is a condition that can be expressed after COVID-19 contagion, lasting for months or even years, affecting the routine and quality of life of individuals. Participants expressing CRLTTI, with a minimum of 2 months, attested by PCR-RT test were assessed for taste and smell, and underwent experimental treatments in 6 distinct groups: Photobiomodulation (PBM) in tongue dorsum and lateral (660 nm, 808 nm, association of 660 and 808 nm), Transmucosal Laser Irradiation of Blood (TLIB)-ventral surface of tongue (660 nm), B complex supplementation, and Sham laser. No intergroup statistical differences were observed at the final evaluation, despite the tendencies of better results with PBM and TLIB observed. PBM, TLIB, and B complex might be treatment options in the management of CRLTTI, despite the lack of total remission of taste and smell perception after 8 sessions (PBM and TLIB) or 30 days of B complex supplementation.

Abstract
Thiamine (thiamin, B1) is a vitamin necessary for proper cell function. It exists in a free form as a thiamine, or as a mono-, di- or triphosphate. Thiamine plays a special role in the body as a coenzyme necessary for the metabolism of carbohydrates, fats and proteins. In addition, it participates in the cellular respiration and oxidation of fatty acids: in malnourished people, high doses of glucose result in acute thiamine deficiency. It also participates in energy production in the mitochondria and protein synthesis. In addition, it is also needed to ensure the proper functioning of the central and peripheral nervous system, where it is involved in neurotransmitter synthesis. Its deficiency leads to mitochondrial dysfunction, lactate and pyruvate accumulation, and consequently to focal thalamic degeneration, manifested as Wernicke's encephalopathy or Wernicke-Korsakoff syndrome. It can also lead to severe or even fatal neurologic and cardiovascular complications, including heart failure, neuropathy leading to ataxia and paralysis, confusion, or delirium. The most common risk factor for thiamine deficiency is alcohol abuse. This paper presents current knowledge of the biological functions of thiamine, its antioxidant properties, and the effects of its deficiency in the body.

Cancers (Basel) 2023; 15:4938. [PMID: 37894305 PMCID: PMC10605534 DOI: 10.3390/cancers15204938] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Revised: 10/06/2023] [Accepted: 10/10/2023] [Indexed: 10/29/2023] Open
Abstract
The management of patients with vitamin B12 deficiency after total gastrectomy (TG) remains controversial. We aimed to evaluate the effect of vitamin B12 replacement intervals on the clinical characteristics in these patients. The data from patients who received vitamin B12 supplementation after TG between 2007 and 2018 at the National Cancer Center, Korea, were retrospectively evaluated. Vitamin B12 deficiency was defined as a serum vitamin B12 level of <200 pg/mL or urine methylmalonic acid level > 3.8 mg/gCr. The patients were divided into a regular replacement group (patients received an intramuscular injection or oral medication regularly), and a lab-based replacement group (patients received vitamin B12 intermittently after checking the level). The symptoms and biochemical parameters were compared between these groups. The regular and lab-based replacement groups included 190 and 216 patients, respectively. The median vitamin B12 replacement intervals were 1 and 9 months, respectively (p < 0.001). After replacement, the regular replacement group had higher vitamin B12 levels than the lab-based replacement group (p < 0.001). However, the serum hemoglobin level showed no significant changes. After replacement, there was no significant difference in the proportion of the symptomatic patients between the groups. Replacing vitamin B12 with a lab-based protocol may be sufficient for TG patients.

Abstract
Notably the integration of additives such as growth factors, vitamins, and drugs with scaffolds promoted nerve tissue engineering. This study tried to provide a concise review of all these additives that facilitates nerve regeneration. An attempt was first made to provide information on the main principle of nerve tissue engineering, and then to shed light on the effectiveness of these additives on nerve tissue engineering. Our research has shown that growth factors accelerate cell proliferation and survival, while vitamins play an effective role in cell signalling, differentiation, and tissue growth. They can also act as hormones, antioxidants, and mediators. Drugs also have an excellent and necessary effect on this process by reducing inflammation and immune responses. This review shows that growth factors were more effective than vitamins and drugs in nerve tissue engineering. Nevertheless, vitamins were the most commonly used additive in the production of nerve tissue.

Abstract
Trace elements and vitamins, collectively known as micronutrients, are essential for basic metabolic reactions in the human body. Their deficiency or, on the contrary, an increased amount can lead to serious disorders. Research in recent years has shown that long-term abnormal levels of micronutrients may be involved in the etiopathogenesis of some neurological diseases. Acute and chronic alterations in micronutrient levels may cause other serious complications in neurological diseases. Our aim was to summarize the knowledge about micronutrients in relation to selected neurological diseases and comment on their importance and the possibilities of therapeutic intervention in clinical practice.

Abstract
BACKGROUND Congenital thumb duplication comes under the Wassel type IV classification is the hypoplastic variety, with the extra digit growing from the dominant thumb's soft tissue alone. Excising the hypoplastic finger while reconstructing for the retained one has been the most adopted approach. Tourniquets are commonly utilized tools in orthopedic surgeries to reduce the amount of blood, thus enhancing the visibility. Unfortunately, tourniquet-related nerve injury (TNRI) is gaining more attention as a serious complication of tourniquet use in surgery. CASE REPORT A 13-year-old Asian boy with preaxial polydactyly Wassel type IV of the right hand underwent reconstruction surgery. A pneumatic tourniquet was applied at 200 mmHg on the right mid-upper arm and maintained for 90 min. After the surgery, the patient had total weakness with numbness, tingling, and burning sensation from his right upper arm to his fingertips. The neurological examination and nerve conduction studies (NCS) results were consistent with axonotmesis lesions. Pharmacological and physical rehabilitation therapy had successfully restored full motoric and sensory function after 6 months. CONCLUSIONS Nerve injury should be acknowledged as a possible complication from routinely-utilized tourniquets in orthopedic surgeries. Our cases may expand the need for further studies to establish a guideline for tourniquet use and TRNI management.

Abstract
This study evaluated and compared the functional recovery and histopathological outcomes of treatment involving low-intensity pulsed ultrasound (LIPUS) and methylcobalamin (B12) on brachial plexus injury (BPI) in an experimental rat model. Three days after BPI, the rats were assigned to receive either LIPUS or methylcobalamin alone or in combination consecutively for 12 days. Serial changes in sensory and motor behavioral responses, as well as morphological and immunohistochemical changes for substance P (SP), ionized calcium-binding adapter molecule 1 (iba1), brain-derived neurotrophic factor (BDNF), and S100 were examined 28 days after BPI as the outcome measurements. Early intervention of LIPUS and methylcobalamin, whether alone or in combination, augmented the sensory and motor behavioral recovery as well as modulated SP and iba1 expression in spinal dorsal horns, BDNF, and S100 in the injured nerve. Moreover, the combined therapy with its synergistic effect gave the most beneficial effect in accelerating functional recovery. In view of the effective initiation of early recovery of sensory and motor functions, treatment with LIPUS and methylcobalamin in combination has a potential role in the clinical management of early-phase BPI.

Abstract
This study investigated the ameliorating effects of a natural antioxidant formula (NAF) consisting of Ginkgo biloba leaf extract, docosahexaenoic acid/eicosapentaenoic acid, ferulic acid, flaxseed oil, vitamin E, and vitamin B12 on a lipopolysaccharide (LPS)-induced cognitive dysfunction model in rats. Six-week-old rats received a diet containing 0.5% (w/w) NAF for 38 days from Day 1, and LPS (1 mg/kg body weight) was administered intraperitoneally once daily on Days 8 and 10. On Day 11, LPS alone increased interleukin-1β and tumor necrosis factor-α in the hippocampus and cerebral cortex and the numbers of M1-type microglia/macrophages and GFAP+ reactive astrocytes in the hilus of the hippocampal dentate gyrus. NAF treatment decreased brain proinflammatory cytokine levels and increased the number of M2-type microglia/macrophages. During Days 34-38, LPS alone impaired fear memory acquisition and the extinction learning process, and NAF facilitated fear extinction learning. On Day 38, LPS alone decreased the number of type-3 neural progenitor cells in the hippocampal neurogenic niche, and NAF restored the number of type-3 neural progenitor cells and increased the numbers of both immature granule cells in the neurogenic niche and reelin+ hilar interneurons. Thus, NAF exhibited anti-inflammatory effects and ameliorated LPS-induced adverse effects on hippocampal neurogenesis and fear memory learning, possibly through amplification of reelin signaling by hilar interneurons. These results suggest that neuroinflammation is a key factor in the development of LPS-induced impairment of fear memory learning, and supplementation with NAF in the present study helped to prevent hippocampal neurogenesis and disruptive neurobehaviors caused by neuroinflammation.

Abstract
Alzheimer's disease (AD) is a brain disorder that progressively undermines memory and thinking skills by affecting the hippocampus and entorhinal cortex. The main histopathological hallmarks of AD are the presence of abnormal protein aggregates (Aβ and tau), synaptic dysfunction, aberrant proteostasis, cytoskeletal abnormalities, altered energy homeostasis, DNA and RNA defects, inflammation, and neuronal cell death. However, oxidative stress or oxidative damage is also evident and commonly overlooked or considered a consequence of the advancement of dementia symptoms. The control or onset of oxidative stress is linked to the activity of the amyloid-β peptide, which may serve as both antioxidant and pro-oxidant molecules. Furthermore, oxidative stress is correlated with oxidative damage to proteins, nucleic acids, and lipids in vulnerable cell populations, which ultimately lead to neuronal death through different molecular mechanisms. By recognizing oxidative stress as an integral feature of AD, alternative therapeutic or preventive interventions are developed and tested as potential or complementary therapies for this devastating neurodegenerative disease.

Blood-letting therapy combined with Master Tung's Five-tiger Point Scraping (Gua Sha) for patients with hematological malignancy and chemotherapy-induced peripheral neuritis. Am J Transl Res 2023; 15:5304-5313. [PMID: 37692923 PMCID: PMC10492046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Accepted: 08/12/2023] [Indexed: 09/12/2023]
Abstract
OBJECTIVE To investigate the clinical efficacy of Shixuan and Qiduan blood-letting therapy combined with Master Tung's Five-tiger Point (11.27) Scraping for patients with hematological malignancy and peripheral neuritis. METHODS A total of 70 patients with hematological malignancy who were admitted to Langfang TCM Hospital between January 2020 and December 2022 for treating chemotherapy-induced peripheral neuritis were enrolled retrospectively. The patients were divided into a single treatment group that received western nutritional interventions alone, and a combined treatment group that underwent additional Traditional Chinese Medicine (TCM) Shixuan and Qiduan blood-letting therapy, along with Master Tung's Five-tiger Point (11.27) Scraping. Statistical analyses were carried out to compare the clinical efficacy of the two treatment plans in the patients. Scores of sensory disturbance rating (SDR), numeric rating scale (NRS) for pain, nail fold microcirculation (NFM) of the infected extremity, and the quality of life (QoL), as well as the motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of the median and peroneal nerves of patients in both groups were recorded and compared before and after treatment. The incidence rate of adverse events was compared between the two groups. Furthermore, the clinical outcomes of patients in the two groups were followed up and analyzed for correlated factors using univariate and multivariate analyses. RESULTS The clinical efficacy rate achieved by the combined therapy was 88.57%, significantly higher than 68.57% for patients undergoing single therapy (P=0.041). Moreover, the scores of SDR, pain NRS, QoL, and NFM of the affected extremity, as well as the MNCV and SNCV of patients in the two groups were all improved after treatment, with better improvements in the combined treatment group than in the single treatment group. The incidence rate of adverse events was higher in the single treatment group compared to that of the combined treatment group (17.14% vs. 11.42%) (P=0.466). In addition, during the six-month follow-up period, a total of 27 patients in both groups developed chronic neural disorders. Logistic regression analysis revealed that the MNCV and SNCV of the median and peroneal nerves, together with the duration of chemotherapy, served as independent influencing factors. CONCLUSION Shixuan and Qiduan blood-letting therapy combined with Master Tung's Five-tiger Point (11.27) Scraping could improve the SDR and pain NRS scores, facilitate the recovery of neural functions, and advance the QoL of patients with chemotherapy-induced peripheral neuritis without increasing the risk of adverse reactions.
