Exploring the link between genetic polymorphisms in folate metabolism genes (MTHFR, MTR, and MTRR) and cardiovascular disease (CVD), this study evaluates the effect of B vitamin supplements (methylfolate, pyridoxal-5\'-phosphate, and methylcobalamin) on homocysteine and lipid levels, potentially guiding personalized CVD risk management. In a randomized, double-blind, placebo-controlled trial, 54 patients aged 40-75 with elevated homocysteine and moderate LDL-C levels were divided based on MTHFR, MTR, and MTRR genetic polymorphisms. Over six months, they received either a combination of methylfolate, P5P, and methylcobalamin, or a placebo. At the 6 months follow-up, the treatment group demonstrated a significant reduction in homocysteine levels by 30.0% (95% CI: -39.7% to -20.3%) and LDL-C by 7.5% (95% CI: -10.3% to -4.7%), compared to the placebo (p < 0.01 for all). In the subgroup analysis, Homozygous Minor Allele Carriers showed a more significant reduction in homocysteine levels (48.3%, 95% CI: -62.3% to -34.3%, p < 0.01) compared to mixed allele carriers (18.6%, 95% CI: -25.6% to -11.6%, p < 0.01), with a notable intergroup difference (29.7%, 95% CI: -50.7% to -8.7%, p < 0.01). LDL-C levels decreased by 11.8% in homozygous carriers (95% CI: -15.8% to -7.8%, p < 0.01) and 4.8% in mixed allele carriers (95% CI: -6.8% to -2.8%, p < 0.01), with a significant between-group difference (7.0%, 95% CI: -13.0% to -1.0%, p < 0.01). Methylfolate, P5P, and methylcobalamin supplementation tailored to genetic profiles effectively reduced homocysteine and LDL-C levels in patients with specific MTHFR, MTR, and MTRR polymorphisms, particularly with homozygous minor allele polymorphisms.

The mass extinction of amphibians necessitates specialized programs to ensure species\' survival. Maryland Zoo in Baltimore houses the largest assurance population of the critically endangered Panamanian golden frog (Atelopus zeteki). However, individuals in this population experience a tetany-like syndrome, characterized by rigid/inappropriately positioned limbs and difficulty hopping, swimming, and righting. In this study, a syndrome case definition was assigned and the associated clinical signs were described. Then, four different treatments were systematically assessed in order to find the most effective protocol for treatment and begin to elucidate its underlying causes. Eighty-three frogs fulfilled the case definition and were treated orally for 14 d with either calcium gluconate, magnesium chloride, supplemental gavage feeding, or combination of calcium, magnesium, and vitamin B complex. Frogs were tested with a defined protocol assessing hopping, righting, and swimming abilities. Testing was performed at symptom onset and repeated weekly until resolution occurred. Analyses revealed that combination treatment was significantly more effective in eliminating clinical signs of tetany syndrome. Results show the most effective way to treat this syndrome, but do not help elucidate the underlying cause. Future work will focus on examining factors (e.g., diet, husbandry) that may elicit the syndrome for a more complete understanding of its etiology.

BACKGROUND: Musculoskeletal disorders are an important cause of work absence. Clinical practice guidelines recommend nonsteroidal anti-inflammatory drugs (NSAIDs) for grade I-II cervical sprains. The combination of thiamine + pyridoxine + cyanocobalamin vitamins has been used, alone and in combination with NSAIDs, for pain and inflammation in musculoskeletal disorders.
OBJECTIVE: The objective of this study was to demonstrate the analgesic synergy of dexketoprofen, and the combination of vitamins thiamine + pyridoxine + cyanocobalamin in a fixed-dose combination (FDC) for the treatment of acute pain caused by grade I-II cervical sprains.
METHODS: We conducted a multicentre, prospective, randomized, double-blind, phase IIIb clinical study comparing two treatment groups: (1) dexketoprofen 25 mg/vitamin B (thiamine 100 mg, pyridoxine 50 mg and cyanocobalamin 0.50 mg) in an FDC (two or more active ingredients combined in a single dosage form) versus (2) dexketoprofen 25 mg monotherapy (single drug to treat a particular disease), one capsule or tablet orally, every 8 h for 7 days. Final mean, average change, and percentage change in pain perception (measured using a visual analogue scale [VAS]) were compared with baseline between groups. A p value < 0.05 was considered statistically significant. Analyses were conducted using SPSS software, v.29.0.
RESULTS: A statistically significant reduction in pain intensity was observed from the third day of treatment with the FDC compared with monotherapy (- 3.1 ± - 1.5 and - 2.6 ± - 1.1 cm, respectively) measured using the VAS (p = 0.011). Regarding the degree of disability, using the Northwick Park Neck Pain Questionnaire (NPQ), statistical difference was observed for the final measurement (7.5%, interquartile range [IQR] 2.5, 10.5; vs. 7.9%, IQR 5.0, 13.8; p = 0.028). A lower proportion of adverse events was reported when using the FDC.
CONCLUSIONS: The FDC of dexketoprofen/thiamine + pyridoxine + cyanocobalamin vitamins demonstrated superior efficacy and a better safety profile compared with dexketoprofen monotherapy for pain treatment in patients with grade I-II cervical sprains.

OBJECTIVE: Feeding intolerance (FI) is a common problem in late preterm infants (34 weeks ≤ gestational age < 37 weeks). This study aimed to evaluate the efficacy and safety of phentolamine combined with B vitamins in treating FI in late preterm infants and to explore its effects on gastrointestinal symptoms, inflammation and complications.
METHODS: We randomly assigned 118 late preterm infants with FI to a treatment group (n = 56) or a control group (n = 62). The treatment group received intravenous phentolamine and intramuscular B vitamins, whereas the control group received basic treatment only. We measured the time of disappearance of gastrointestinal symptoms, the time of basal at-tainment, the time of hospitalisation, the incidence of complications, the concentrations of inflammatory markers and the overall effective rate of treatment.
RESULTS: The treatment group had a shorter duration of gastrointestinal symptoms than did the control group (p < 0.01). The treatment group also had lower concentrations of inflammatory markers and a higher overall effective rate than did the control group (p < 0.05). There was no difference between the two groups in the time of hospitalisation, basal attainment, weight re-covery and the incidence of complications (p > 0.05).
CONCLUSIONS: Phentolamine and B vitamins can reduce gastrointestinal symptoms and inflammation in late preterm infants with FI but do not affect the occurrence of complications.

BACKGROUND: Numerous researches have indicated a correlation between the intake of dietary micronutrients and the occurrence of constipation. Nevertheless, the correlation between constipation and vitamin B1 remains uninvestigated. The main aim of this research was to examine the association between chronic constipation and the consumption of vitamin B1 in the diet among adult participants of the National Health and Nutrition Examination Survey (NHANES).
METHODS: This study used data from the NHANES, a survey on health and nutrition conducted between 2005 and 2010. The respondents\' dietary information was gathered by utilizing the 24-hour dietary records. Various statistical analyses, such as multiple logistic regression, subgroup analysis, and curve-fitting analysis, were employed to investigate the correlation between dietary intake of vitamin B1 and chronic constipation.
RESULTS: In the trial, there were 10,371 participants, out of which 1,123 individuals (10.8%) were identified as having chronic constipation. Fully adjusted multiple logistic regression analyses showed that increasing dietary intake of vitamin B1 (OR = 0.87, 95% CI: 0.77-0.99) was significantly associated with a reduced risk of constipation. Following adjustment for multiple variables in Model 3, the odds ratio (OR) and 95% confidence interval (CI) for the third tertile, in comparison to the first tertile (reference group), was 0.80 (0.65, 0.99). In addition, subgroup analyses and interaction tests showed a significant inverse association between vitamin B1 intake and the prevalence of constipation, especially among men, non-hypertensive, and non-diabetic individuals (all P-values less than 0.05).
CONCLUSIONS: This research uncovered an inverse correlation between the consumption of vitamin B1 in the diet and the occurrence of chronic constipation. One potential explanation for this phenomenon is that the consumption of vitamin B1 in one\'s diet is linked to the softening of stools and an augmented occurrence of colonic peristalsis. Additional extensive prospective research is required to thoroughly examine the significance of thiamine in long-term constipation.

BACKGROUND: The main objective of this study was to evaluate the neurological consequences of delayed pyridoxine administration in patients diagnosed with Pyridoxin Dependent Epilepsies (PDE).
METHODS: We reviewed 29 articles, comprising 52 genetically diagnosed PDE cases, ensuring data homogeneity. Three additional cases were included from the General Pediatric Operative Unit of San Marco Hospital. Data collection considered factors like age at the first seizure\'s onset, EEG reports, genetic analyses, and more. Based on the response to first-line antiseizure medications, patients were categorized into four distinct groups. Follow-up evaluations employed various scales to ascertain neurological, cognitive, and psychomotor developments.
RESULTS: Our study includes 55 patients (28 males and 27 females), among whom 15 were excluded for the lack of follow-up data. 21 patients were categorized as \"Responder with Relapse\", 11 as \"Resistant\", 6 as \"Pyridoxine First Approach\", and 2 as \"Responders\". The neurological outcome revealed 37,5 % with no neurological effects, 37,5 % showed complications in two developmental areas, 15 % in one, and 10 % in all areas. The statistical analysis highlighted a positive correlation between the time elapsed from the administration of pyridoxine after the first seizure and worse neurological outcomes. On the other hand, a significant association was found between an extended latency period (that is, the time that elapsed between the onset of the first seizure and its recurrence) and worse neurological outcomes in patients who received an unfavorable score on the neurological evaluation noted in a subsequent follow-up.
CONCLUSIONS: The study highlights the importance of early recognition and intervention in PDE. Existing medical protocols frequently overlook the timely diagnosis of PDE. Immediate administration of pyridoxine, guided by a swift diagnosis in the presence of typical symptoms, might improve long-term neurological outcomes, and further studies should evaluate the outcome of PDE neonates promptly treated with Pyridoxine.

UNASSIGNED: The purpose of this study is to explore the effect of vitamin B complex supplementation following periodontal flap surgery on clinical and microbiological parameters.
UNASSIGNED: A randomized controlled trial on 10 patients with periodontitis in split-mouth design was undertaken to find the effect of vitamin B complex supplementation with open flap debridement on periodontal wound healing. Multiplex polymerase chain reaction (PCR) for Tannerella forsythus and Porphyromonas gingivalis was done using subgingival plaque samples at 0 and 90th day.
UNASSIGNED: The results showed a significant reduction (P < 0.01) of clinical (plaque index, gingival index, gingival bleeding index, probing pocket depth, and relative attachment level) and microbial profile in both treatment groups, whereas on intergroup analysis, more reduction in all clinical parameters were observed in the test group, but statistically, the results were insignificant.

UNASSIGNED: The study aimed to understand the cause of glossitis that occurred among boarding students in a central school in Chhukha, Bhutan, and the outcome after 15 days of treatment with a vitamin B complex tablet.
UNASSIGNED: The researcher extracted data from the treatment records of patients treated for glossitis from 30 September 2020 to 30 October 2020 at the boarding school and conducted a retrospective descriptive study. A total of 97 records were used in the study: the age, gender,date of reporting to school, treatment, dietary preferences, and outcome of treatment.
UNASSIGNED: In all, 63 (64.9%) patients were females. The students who were staying in the hostel for longer duration were more in proportion among the patients. About 80% of the patients had subjective improvement after treatment with two doses of one tablet of vitamin B complex tablet for 15 days. There were no deaths.
UNASSIGNED: The study could not ascertain the definite cause of glossitis among boarding students but 80 % of the patients showed subjective improvement after treatment with daily two doses of 32.5 mg of vitamin B complex tablet. The study recommends a prospective study to understand the cause of glossitis among boarding students to prevent similar future outbreaks.

OBJECTIVE: The aim was to study the association between dietary intake of B vitamins in childhood and the risk of islet autoimmunity (IA) and progression to type 1 diabetes (T1D) by the age of 10 years.
METHODS: We followed 8500 T1D-susceptible children born in the U.S., Finland, Sweden, and Germany in 2004 -2010 from the Environmental Determinants of Diabetes in the Young (TEDDY) study, which is a prospective observational birth cohort. Dietary intake of seven B vitamins was calculated from foods and dietary supplements based on 24-h recall at 3 months and 3-day food records collected regularly from 6 months to 10 years of age. Cox proportional hazard models were adjusted for energy, HLA-genotype, first-degree relative with T1D, sex, and country.
RESULTS: A total of 778 (9.2) children developed at least one autoantibody (any IA), and 335 (3.9%) developed multiple autoantibodies. 280 (3.3%) children had IAA and 319 (3.8%) GADA as the first autoantibody. 344 (44%) children with IA progressed to T1D. We observed that higher intake of niacin was associated with a decreased risk of developing multiple autoantibodies (HR 0.95; 95% CI 0.92, 0.98) per 1 mg/1000 kcal in niacin intake. Higher intake of pyridoxine (HR 0.66; 95% CI 0.46, 0.96) and vitamin B12 (HR 0.87; 95% CI 0.77, 0.97) was associated with a decreased risk of IAA-first autoimmunity. Higher intake of riboflavin (HR 1.38; 95% CI 1.05, 1.80) was associated with an increased risk of GADA-first autoimmunity. There were no associations between any of the B vitamins and the outcomes \"any IA\" and progression from IA to T1D.  CONCLUSION: In this multinational, prospective birth cohort of children with genetic susceptibility to T1D, we observed some direct and inverse associations between different B vitamins and risk of IA.

OBJECTIVE: To develop a predictive model for thiamine responsive disorders (TRDs) among infants and young children hospitalized with signs or symptoms suggestive of thiamine deficiency disorders (TDDs) based on response to therapeutic thiamine in a high-risk setting.
METHODS: Children aged 21 days to <18 months hospitalized with signs or symptoms suggestive of TDD in northern Lao People\'s Democratic Republic were treated with parenteral thiamine (100 mg daily) for ≥3 days in addition to routine care. Physical examinations and recovery assessments were conducted frequently for 72 hours after thiamine was initiated. Individual case reports were independently reviewed by three pediatricians who assigned a TRD status (TRD or non-TRD), which served as the dependent variable in logistic regression models to identify predictors of TRD. Model performance was quantified by empirical area under the receiver operating characteristic curve.
RESULTS: A total of 449 children (median [Q1, Q3] 2.9 [1.7, 5.7] months old; 70.3% exclusively/predominantly breastfed) were enrolled; 60.8% had a TRD. Among 52 candidate variables, those most predictive of TRD were exclusive/predominant breastfeeding, hoarse voice/loss of voice, cyanosis, no eye contact, and no diarrhea in the previous 2 weeks. The area under the receiver operating characteristic curve (95% CI) was 0.82 (0.78, 0.86).
CONCLUSIONS: In this study, the majority of children with signs or symptoms of TDD responded favorably to thiamine. While five specific features were predictive of TRD, the high prevalence of TRD suggests that thiamine should be administered to all infants and children presenting with any signs or symptoms consistent with TDD in similar high-risk settings. The usefulness of the predictive model in other contexts warrants further exploration and refinement.
