Abstract
Multiple sclerosis (MS) is a neurodegenerative condition that results in axonal and permanent damage to the central nervous system, necessitating healing owing to autoimmune reactions and persistent neuroinflammation. Antioxidant and anti-inflammatory drugs are essential for the management of oxidative stress and neuroinflammation. Additionally, multivitamin supplementation, particularly vitamin B12 (cobalamin), may be beneficial for neuronal protection. Although there is no documented connection between vitamin B12 deficiency and MS, researchers have explored its potential as a metabolic cause. This review highlights the therapeutic benefits of cobalamin (Cbl) in patients with MS.

Cardiac and Liver Fibrosis Assessed by Multiparametric MRI in Patients with Fontan Circulation. Pediatr Cardiol 2024:10.1007/s00246-024-03522-9. [PMID: 38771376 DOI: 10.1007/s00246-024-03522-9] [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: 03/19/2024] [Accepted: 05/06/2024] [Indexed: 05/22/2024]
Abstract
The abnormal hemodynamics in Fontan circulation due to persistently increased systemic venous pressure results in hepatic venous congestion and Fontan-associated liver disease. Combined assessment of cardiac and liver fibrosis and cardiac remodeling using multiparametric MRI in this context have not been fully explored. To evaluate cardiac and liver fibrosis and cardiac remodeling using multiparametric MRI in patients who have undergone Fontan procedures. Thirty-eight patients and 23 controls underwent cardiac and liver MRI examinations in a 3.0-T scanner. Mann-Whitney, Fisher exact test, and Spearman's correlation were applied to evaluate myocardial volumes, function, native cardiac and liver T1 mapping, ECVs and liver stiffness. The mean native cardiac T1 value (p = 0.018), cardiac ECV (p < 0.001), liver native T1 (p < 0.001), liver ECV (p < 0.001), and liver stiffness (p < 0.001) were higher in patients than controls. The indexed end-diastolic volume (EDVi) correlated with the myocardial ECV (r = 0.356; p = 0.033), native liver T1 (r = 0.571; p < 0.001), and with liver stiffness (r = 0.391; p = 0.015). In addition, liver stiffness correlated with liver ECV (r = 0.361; p = 0.031) and native liver T1 (r = 0.458; p = 0.004). An association between cardiac remodeling and cardiac and liver fibrosis were found in this population. The usefulness of MRI to follow cardiac and liver involvement in these patients is critical to improve treatment strategies and to prevent the need for combined liver and heart transplantation.

Abstract
Obesity, whose prevalence is increasing globally, is malnutrition that causes micro/macronutrients and vitamin deficiencies in adolescents. Vitamin B12 plays a prominent role in the body systems such as remethylation, deoxidation, and DNA synthesis. We aimed to examine the relationship between severe obese/obese adolescents and vitamin B12 levels in this study. This study was conducted as a case-control study consisting of 44 obese and 40 healthy control adolescents aged 11-17 years. Obesity was diagnosed using body mass index (BMI) charts defined by the World Health Organization according to age and gender. Vitamin B12 deficiency was found to be 34.1% in the patient obesity group, while it was 12.5% in the control group (p = 0.02). Homeostatic Model Assessment for Insulin Resistance levels were found to be 3.09 (1.9-5.29) higher in the severely obese group (p < 0.001). The median level of vitamin B12 in the obese group was 173 (122.5-220.7) in the severe obese group, 197 (146.5-302.7) in the obese group, and 252.5 (192.8-302) in the control group (p = 0.021). We found that obesity has a 1.6-fold decreasing effect on vitamin B12 levels. This study shows the clinician the importance of monitoring BMI and vitamin B12 levels in obese adolescents, given the effects of vitamin B12 on neuronal migration, metabolic reactions, and many systems in the body. Further researches are needed to investigate the pathophysiology and effect of low vitamin B12 levels in obese adolescents.

AMERICAN JOURNAL OF CASE REPORTS 2024; 25:e942553. [PMID: 38332578 PMCID: PMC10862081 DOI: 10.12659/ajcr.942553] [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: 09/14/2023] [Revised: 12/30/2023] [Accepted: 12/22/2023] [Indexed: 02/10/2024]
Abstract
BACKGROUND Fermented foods, such as yogurt, are often considered healthy; however, there have been numerous reported cases of bacteremia associated with their consumption. In this report, we present a case of Bacillus subtilis var. natto (B. subtilis var. natto) bacteremia related to the consumption of natto, a traditional Japanese food made from fermented soybeans. We also conducted a literature review on B. subtilis bacteremia. CASE REPORT We report the case of a 41-year-old woman who presented with fever, had a medical history of congenital liver fibrosis, and experienced recurrent B. subtilis var. natto bacteremia along with acute cholangitis. Although she discontinued eating natto, she developed pyogenic thrombophlebitis due to B. subtilis var. natto. We successfully treated her with meropenem and an anti-coagulant. To investigate the management and prognosis of B. subtilis var. natto bacteremia, we conducted a literature review of B. subtilis intra-abdominal infection. We identified 17 papers describing 30 cases of B. subtilis intra-abdominal infection, 4 cases of which were caused by B. subtilis var. natto; the median age of the patients was 71 years (range, 15-96 years), 14 patients (47%) were female, and 3 patients (10%) died. From our findings, our case was the only one of recurrent B. subtilis var. natto infection. Even after patients discontinue eating natto, they should be carefully monitored. CONCLUSIONS Due to advancements in PCR identification techniques, case reports of infections caused by B. subtilis var. natto are increasing.

Abstract
Congenital hepatic fibrosis is a rare, autosomal recessive, fibro-polycystic disease resulting from ductal plate malformation, leading to proliferation and fibrosis of bile ducts. Progressive hepatic fibrosis leads to portal hypertension and varices which can present with life threatening gastrointestinal hemorrhage. We report a case of congenital hepatic fibrosis in a 2-year-old child who presented with 8 days of fever without any significant medical history or physical examination findings.

Abstract
Fibrotic diseases result in organ remodelling and dysfunctional failure and account for one-third of all deaths worldwide. There are no ideal treatments that can halt or reverse progressive organ fibrosis, moreover, organ transplantation is complicated by problems with a limited supply of donor organs and graft rejection. The development of new approaches, especially induced pluripotent stem cell (iPSC)-based therapy, is becoming a hot topic due to their ability to self-renew and differentiate into different cell types that may replace the fibrotic organs. In the past decade, studies have differentiated iPSCs into fibrosis-relevant cell types which were demonstrated to have anti-fibrotic effects that may have the potential to inform new effective precision treatments for organ-specific fibrosis. In this review, we summarize the potential of iPSC-based cellular approaches as therapeutic avenues for treating organ fibrosis, the advantages and disadvantages of iPSCs compared with other types of stem cell-based therapies, as well as the challenges and future outlook in this field.
