RESUMO

Nutritional peripheral neuropathies are a global problem, heavily influenced by geopolitical, cultural and socioeconomic factors. Peripheral neuropathy occurs most frequently secondary to B-vitamin deficiencies, which is suspected to increase in years to come due to the popularity of vegan and vegetarian diets and increased use of bariatric surgery.This review will focus on the common B-vitamins for which a causal link to peripheral neuropathy is more established (vitamins B1, B2, B6, B9 and B12). We will review the historical human and animal data on which much of the clinical descriptions of vitamin deficiencies are based and summarise current available tools for accurately diagnosing a nutritional deficiency. We will also review recently described genetic diseases due to pathogenic variants in genes involved in B-vitamin metabolism that have helped to inform the phenotypes and potential causality of certain B-vitamins in peripheral neuropathy (B2 and B9).Endemic outbreaks of peripheral neuropathy over the last two centuries have been linked to food shortages and nutritional deficiency. These include outbreaks in Jamaican sugar plantation workers in the nineteenth century (Strachan's syndrome), World War two prisoners of war, Cuban endemic neuropathy and also Tanzanian endemic optic neuropathy, which remains a significant public health burden today. An improved understanding of lack of which vitamins cause peripheral neuropathy and how to identify specific deficiencies may lead to prevention of significant and irreversible disability in vulnerable populations.

RESUMO

PURPOSE: Chronic pancreatitis (CP) leads to diabetes and pancreatic exocrine insufficiency (PEI). PEI may lead to maldigestion and malnutrition, which may cause fat-soluble vitamin deficiency, sarcopenia and abnormal bone density. We aim to study the prevalence of osteoporosis, sarcopenia and vitamin deficiency among CP patients. METHODS: Long-term (4-5 years) follow-up was implemented on CP patients. We recorded CP duration, BMI, smoking, alcohol consumption and medication. We determined the serum values for A, D and E vitamins, albumin, creatinine, haemoglobin, calcium and magnesium. Bone density measurement was taken from the proximal femur and lumbar spine. CT/MRI scans were used to measure for psoas muscle area. RESULTS: A total of 33 patients (median age 62 [39-81] years, 61% male) were included. None of these patients had earlier diagnosis of osteopathy, and none of them had known vitamin deficiency or were sarcopenic. Nineteen patients (57%) had pancreatic exocrine insufficiency and of these seven patients (37%) had no pancreatic enzyme replacement therapy (PERT) and one (5%) had inadequate enzyme therapy. During the study, osteoporosis was diagnosed in 20% and possible sarcopenia in 48% of patients. PEI and inadequate PERT was associated with low E vitamin levels (75% vs. 0%, p = 0.012), higher risk of osteoporosis (43% vs. 5.6%, p = 0.013) and sarcopenia (80% vs. 36%, p = 0.044). CONCLUSION: This study demonstrates that chronic pancreatitis is associated with osteoporosis, sarcopenia and vitamin deficiency. If untreated, pancreatic exocrine insufficiency is associated with increased risk of these outcomes. This highlights the importance of identifying and treating PEI in CP patients.

RESUMO

Patients with cystic fibrosis (CF) are at high risk of fat-soluble vitamin deficiencies, even with supplementation. The contribution of a suboptimal vitamin K status to respiratory and endocrine pathophysiology in CF has been inadequately characterized. This is a cross-sectional study in adult CF patients (≥18 years old) from the Montreal Cystic Fibrosis Cohort. Vitamin K1 (VK1) was measured with high-performance liquid chromatography, using fasted serum samples collected during an oral glucose tolerance test (OGTT: 2 h with plasma glucose and insulin every 30 min) (n = 168). Patients were categorized according to VK1 status (suboptimal defined as <0.30 nmol/L). Suboptimal VK1 levels were observed in 66% of patients. Patients with a suboptimal VK1 status have a higher risk of colonization with Pseudomonas aeruginosa (p = 0.001), have lower body mass index (BMI) (p = 0.003), and were more likely to have exocrine pancreatic insufficiency (p = 0.002). Using an established threshold for VK1, we did show significantly reduced OGTT-derived measures of insulin secretion in patients with a VK1 status below 0.30 nmol/L (first- and second-phase area under the curve (AUC)INS/GLU (p = 0.002 and p = 0.006), AUCINS (p = 0.012) and AUCINS/GLU (p = 0.004)). Subclinical vitamin K deficiency is more common than other fat-soluble vitamin deficiencies in patients with CF. We demonstrate an association between a suboptimal VK1 status and measures of insulin secretion. We highlight the potential associations of mild vitamin K deficiency with pseudomonal colonization and lower BMI, although these need to be validated in prospective studies.

RESUMO

ABSTRACT: Pancreatic ductal adenocarcinoma (PDAC) is currently an increasing contributor to cancer-related mortality. Despite advances in cancer treatment, PDAC survival rates have remained roughly unchanged over the years. Specifically, late diagnosis and insensitivity to currently available therapeutic regimens have been identified as the main causes for its poor survival. Pancreatic exocrine insufficiency (PEI) is a typical complication associated with PDAC diagnosis and pancreatic surgery. Pancreatic exocrine insufficiency, a major contributor to maldigestion in PDAC, is often not treated because it remains undetected because of lack of overt signs and symptoms. In this review, we will focus on the major consequences of PEI, including the inadequacy of lipase excretion, which results in deficiency of fat-soluble vitamins. Because PDAC is known for its immune-high jacking mechanisms, we describe key features in which deficiencies of fat-soluble vitamins may contribute to the aggressive biological behavior and immune evasion in PDAC. Because PEI has been shown to worsen survival rates in patients with PDAC, detecting PEI and the related fat-soluble vitamin deficits at the time of PDAC diagnosis is critical. Moreover, timely supplementation of pancreatic enzymes and fat-soluble vitamins may improve outcomes for PDAC patients.

RESUMO

Over the past few years, growing interest has been shown for the impact of dietary requirements and nutritional factors on chronic diseases. As a result, nutritional programs have been reinforced by public health policies. The precise role of micronutrients in chronic liver disease is currently receiving particular attention since abnormalities in vitamin levels are often detected. At present, treatment programs are focused on correcting vitamin deficiencies, which are frequently correlated to higher rates of comorbidities with poor outcomes. The literature reviewed here indicates that liver diseases are often related to vitamin disorders, due to both liver impairment and abnormal intake. More specific knowledge about the role of vitamins in liver disease is currently emerging from various results and recent evidence. The most significant benefits in this area may be observed when improved vitamin intake is combined with a pharmacological treatment that may also affect the progression of the liver disease, especially in the case of liver tumors. However, further studies are needed.

RESUMO

Polycystic ovary syndrome (PCOS) is an increasingly common problem for women in the reproductive age throughout the entire world. A reduction diet with a low glycaemic index (GI) has proved to support the treatment of PCOS. The aim of the study was to analyse the influence of the diet on the level of vitamins soluble in water. The study included 55 women, 40 of which suffered from PCOS (identified by means of the Rotterdam Criteria) and 15 healthy women of the Caucasian race. The level of vitamins before and after the dietary intervention was measured. The diet was a reduction diet with a reduced glycaemic index (GI). Biochemical analyses were made on the basis of liquid chromatography-Infinity 1260 Binary liquid chromatography (LC) Agilent Technology. The level of vitamins in the serum was analysed together with the consumption before and after the dietary intervention. A higher level of vitamin C in the plasma was observed before and after the dietary intervention in the PCOS group in comparison to the control group despite the lower intake of this vitamin in the PCOS group. The remaining vitamins were at a comparable or lower level (B1, B3, B5, B6 and B12). After the dietary intervention, only B1 and B9 were at a clearly lower level (a trend of p = 0.093 and p = 0.085). A properly balanced reduction diet with reduced GI improves the supply of vitamins in women with PCOS. An additional recommendation should be the additional supplementation of B1, niacinamide and the combination of folates with inositol. The level of vitamin C in the plasma may not be a good marker of its supply in the PCOS group.

RESUMO

Background and purpose - There is growing evidence that hypoproteinemia is an important risk factor for adverse events after surgery. Less is known about the impact of vitamin deficiency on postoperative outcome. Therefore we evaluated the prevalence and impact of malnutrition and vitamin deficiency in geriatric patients undergoing elective orthopedic surgery.Patients and methods - In a retrospective analysis of 599 geriatric patients who had undergone elective orthopedic surgery in 2018 and 2019, hypoproteinemia, and deficiency of vitamin D, vitamin B12, and folate were assessed. Reoperation rates, readmission rates, complication rates, and transfusion rates were compared between malnourished patients and patients with normal parameters. Multivariable logistic regression models were used to assess the relationship between malnutrition and postoperative adverse events, controlling for confounding factors such as age, sex, diabetes mellitus, and frailty.Results - Patients with malnutrition showed a higher rate of reoperation (13% vs. 5.5%; p = 0.01) and exhibited more wound-healing disorders (7.4% vs. 1.3%, p = 0.001) as well as Clavien-Dindo IV° complications (7.4% vs. 2.4%; p = 0.03). Deficiency of vitamin D led to a higher rate of falls (8.4% vs. 2.9%, p = 0.006). Deficiency of vitamin B12 and folate did not affect postoperative adverse events. Although correlated to frailty (p = 0.004), multivariable regression analysis identified malnutrition as independent risk factor for reoperation (OR 2.6, 95% CI 1.1-6.2) and wound healing disorders (OR 7.1, CI 1.9-26).Interpretation - Malnutrition is common among geriatric patients undergoing elective orthopedic surgery and represents an independent risk factor for postoperative adverse events.

RESUMO

Idiopathic pulmonary fibrosis (IPF) is a chronic disease mainly associated with aging and, to date, its causes are still largely unknown. It has been shown that dietary habits can accelerate or delay the occurrence of aging-related diseases; however, their potential role in IPF development has been underestimated so far. The present review summarizes the evidence regarding the relationship between diet and IPF in humans, and in animal models of pulmonary fibrosis, in which we discuss the bioactivity of specific dietary food ingredients, including fatty acids, peptides, amino acids, carbohydrates, vitamins, minerals and phytochemicals. Interestingly, many animal studies reveal preventive and therapeutic effects of particular compounds. Furthermore, it has been recently suggested that the lung and gut microbiota could be involved in IPF, a relationship which may be linked to changes in immunological and inflammatory factors. Thus, all the evidence so far puts forward the idea that the gut-lung axis could be modulated by dietary factors, which in turn have an influence on IPF development. Overall, the data reviewed here support the notion of identifying food ingredients with potential benefits in IPF, with the ultimate aim of designing nutritional approaches as an adjuvant therapeutic strategy.

RESUMO

Megaloblastic anemia causes macrocytic anemia from ineffective red blood cell production and intramedullary hemolysis. The most common causes are folate (vitamin B9) deficiency and cobalamin (vitamin B12) deficiency. Megaloblastic anemia can be diagnosed based on characteristic morphologic and laboratory findings. However, other benign and neoplastic diseases need to be considered, particularly in severe cases. Therapy involves treating the underlying cause-eg, with vitamin supplementation in cases of deficiency, or with discontinuation of a suspected medication.

RESUMO

Vitamins are indispensable nutrients for metabolism. Adequate vitamin intake plays vital role in physiological processes including embryonic development, cellular and immunity proliferation and differentiation, DNA synthesis and oxidative response. In contrast, insufficient vitamin levels usually lead to a large number of clinical manifestations including xerophthalmia, nyctalopia, hyperpigmentation, vitiligo, jaundice, megaloblastic anemia, glossitis, scurvy, stroke, cancer, coronary heart disease, Alzheimer's disease, multiple sclerosis and Parkinson's disease. In recent years, more and more researches have focused on the relationship between vitamin family and otorhinolaryngologic diseases. This review will summarize the current knowledge of vitamin family and vitamin-mediated regulating role in those related otorhinolaryngologic diseases.

RESUMO

Heart failure (HF) is a chronic condition with many imbalances, including nutritional issues. Next to sarcopenia and cachexia which are clinically evident, micronutrient deficiency is also present in HF. It is involved in HF pathophysiology and has prognostic implications. In general, most widely known micronutrients are depleted in HF, which is associated with symptoms and adverse outcomes. Nutritional intake is important but is not the only factor reducing the micronutrient availability for bodily processes, because absorption, distribution, and patient comorbidity may play a major role. In this context, interventional studies with parenteral micronutrient supplementation provide evidence that normalization of micronutrients is associated with improvement in physical performance and quality of life. Outcome studies are underway and should be reported in the following years.

RESUMO

This report describes the post-bariatric-surgery evolution of an obese patient who had low adherence to the diet and micronutrient supplementation. Four years after two bariatric surgeries, the patient was admitted due to transient loss of consciousness, slow thinking, anasarca, severe hypoalbuminemia, in addition to vitamin and mineral deficiencies. She had subcutaneous foot abscess but did not present fever. Received antibiotics, vitamins A, D, B12, thiamine, calcium, and parenteral nutrition. After hospitalization (twenty-eight days), there was a significant body weight reduction probably due to the disappearance of clinical anasarca. Parenteral nutrition was suspended after twenty-five days, and the oral diet was kept fractional. After hospitalization (weekly outpatient care), there was a gradual laboratory data improvement, which was now close to the reference values. Such outcome shows the need for specialized care in preventing and treating nutritional complications after bariatric surgeries as well as clinical manifestations of infection in previously undernourished patients.

RESUMO

The study is based on the fact that left atrial (LA) volume measurement is a marker of the presence of diastolic dysfunction and that Vitamin D deficiency may be associated with ventricular remodeling, worsening of left ventricular (LV) diastolic and systolic function, and activation of the renin-angiotensin-aldosterone system. Objective: To evaluate whether LAV changes are related to vitamin D deficiency. Method: A cross-sectional, population-based, unicentric study in which 640 patients over 45 years of age enrolled in the Niterói's Médico de Família program, RJ, were evaluated. Patients were submitted to tissue Doppler echocardiography to evaluate the parameters of diastolic and systolic function and vitamin D dosage. The presence or absence of hypovitaminosis D associated with structural and functional cardiac changes was compared between each group. A p < 0.05 value was considered as an indicator of statistical significance. Results: Of the 640 individuals analyzed, hypovitaminosis D was confirmed in 39.2% of the patients, of whom 34.8% had diastolic dysfunction. The most relevant echocardiographic parameters that were statistically significant were non-indexed AEDs and LAV, E'/A' and E wave deceleration time, which were associated with the presence of hypovitaminosis D (P < 0.01). Conclusion: The study of the association of hypovitaminosis D and the appearance of structural and functional cardiac abnormalities may contribute to the discussion of the adoption of one more criterion to select individuals at risk of developing clinical cardiac insufficiency in primary care since, with the use of echocardiography, the subclinical condition of cardiac involvement, with prognostic and treatment implications for the referred patients with hypovitaminosis D, can be identified early

RESUMO Este relato descreve a evolução pós-cirurgia bariátrica de uma paciente obesa que apresentou baixa adesão à dieta e suplementação de micronutrientes. Quatro anos após duas cirurgias bariátricas, a paciente foi internada por perda transitória de consciência, raciocínio lento, anasarca, hipoalbuminemia grave, além de deficiências vitamínicas e minerais. Apresentava abscesso subcutâneo no pé, mas não apresentava febre. Recebeu antibióticos, vitaminas A, D, B12, tiamina, cálcio e nutrição parenteral. Após a internação (28 dias) houve redução significativa do peso corporal, provavelmente devido ao desaparecimento clínico da anasarca. A nutrição parenteral foi suspensa após 25 dias e a dieta oral foi mantida fracionada. Após a internação (atendimento ambulatorial semanal) houve uma melhora gradativa dos dados laboratoriais, que estavam próximos dos valores de referência. Tal desfecho mostra a necessidade de cuidados especializados na prevenção e tratamento de complicações nutricionais após cirurgias bariátricas, bem como manifestações clínicas de infecção em pacientes previamente desnutridos.

RESUMO

We investigate the long-term effect of very-low dose exposure to a mixture of six pesticides associated with hydrophilic vitamin deficiency on the neurobehavioral outcomes of rats. Two hundred Wistar rats were divided into four groups, two control groups, a vitamin sufficient control group and a vitamin deficiency control group and 2 test groups, a vitamin sufficient test group, and a vitamin deficiency group. The test groups were exposed for 9 months to a mixture of diquat, imazamox, imazethapyr, tepraloxydin, bentazone and acifluorfen in doses of 0.01xNOAEL (mg/kg bw/day). After 9 months of exposure, the behavior changes were evaluated by open field test and elevated plus maze test and the memory was assessed by passive avoidance test. Chronic vitamin deficiency decreased locomotor and special orientation activity and increased anxiety-like behavior in rats. Exposure to very low doses of a mixture of 6 pesticides caused central nervous effects, manifested as decreased locomotor activity, and increased anxiety levels. Vitamin deficiency and low dose chronic pesticides mixture exposure thus affected the central nervous system, especially long-term memory.

RESUMO

BACKGROUND: Anaemia in pregnancy is a common medical condition managed by general practitioners (GPs) in Australia. OBJECTIVE: The aim of this article is to raise awareness of anaemia that occurs in pregnancy, understand its increasing complexities with an expanding migrant population, identify at-risk groups and promote appropriate management. DISCUSSION: With anaemia reportedly occurring in 25% of women in pregnancy and GPs managing the majority of preconception and early pregnancy care, it is important to have a sound understanding of the aetiology, risks and management options. While iron deficiency anaemia is most commonly seen, a more complex understanding in regard to other causes and haemoglobinopathy screening is required.

RESUMO

Hospital mortality of severe sepsis and septic shock is still around 40 % according to recent studies. In accordance to the current sepsis definition, sepsis is a life-threatening organ dysfunction caused by a dysregulated response of the organism to infection. Septic shock is defined by vasopressor-dependent circulatory failure and lactic acidosis. Patients with sepsis and septic shock are often old and/or characterized by severe comorbidities, e. g. tumor or liver disease. These factors also predispose to malnutrition and hence to a corresponding deficiency of essential nutritional components e. g. vitamins. A number of recent studies and reviews have addressed the question whether deficiencies in certain vitamins may facilitate the transition from infection to septic shock. In addition, studies have investigated the effect of high-dose vitamin therapies on sepsis mortality and sepsis-associated organ dysfunctions. This article would like to summarize this current discussion with a focus on vitamin B1 (thiamine), vitamin C and vitamin D.

RESUMO

BACKGROUND: Nutritional deficiencies have been reported in bariatric surgery patients with inconsistent results. However, scarce data exist for Chinese patients. We aimed to assess nutritional deficiencies in Chinese patients undergoing Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), and to identify predictors of postoperative nutritional status. METHODS: A retrospective review of a prospectively collected database was conducted in the patients undergoing RYGB and SG in our hospital between June 2013 and January 2017. Anthropometric data and nutritional data were collected before surgery, at 6 and 12 months postoperatively. RESULTS: This study enrolled 269 patients (120 RYGB, 149 SG). Nutritional deficiencies were common in Chinese bariatric candidates, with vitamin D deficiency the most serious (78.8%), followed by vitamin B1 (39.2%), vitamin B6 (28.0%), folate (26.8%), vitamin C (18.0%) albumin (13.4%), transferrin (11.6%), and phosphorus (11.5%). Despite postoperative routine multivitamin and calcium supplements, nutritional deficiencies were still obvious for RYGB and SG patients. The prevalence of hemoglobin and vitamin B12 deficiencies increased remarkably in the RYGB group; the levels of hemoglobin, globin, vitamin B12, and ferritin decreased significantly (P < 0.05). Preoperative hemoglobin, vitamin B12, and ferritin levels were independently associated with postoperative decrease, respectively. Deficiencies of vitamin D, vitamin B1, vitamin B6, vitamin C, and albumin before surgery were predictors for deficiencies 1 year after surgery, respectively. CONCLUSION: Nutritional deficiencies are common in Chinese bariatric surgery candidates. Similar deficiencies were also seen after RYGB and SG. Routine evaluation and related corrections of preoperative nutritional abnormity could contribute to postoperative nutrient balance.

RESUMO

Hair loss is a common condition that affects most people at some point in their lives. It can exist as an isolated problem or with other diseases and conditions. Androgenetic alopecia (AGA) and its association with the metabolic syndrome (MetS) have received increasing interest since 1972, when the first link between cardiovascular risk factors and hair loss was raised. We have reviewed studies concerning the relationship between alopecia and MetS. Many studies have investigated the relationship among AGA and MetS and its individual components, particularly in men, where a disproportionately large number of these studies supports this association. AGA has also been associated with other metabolic-related conditions, including coronary artery disease, polycystic ovary syndrome, and Cushing syndrome, as well as several nutritional deficiencies, all of which have led to many clinicians advocating for the screening of MetS and cardiovascular risk factors in patients who present with AGA.

RESUMO

The study's objective was to investigate the association between inadequate dietary consumption of micronutrients and indicators of general and abdominal obesity. Cross-sectional analysis of the second wave of the EpiFloripa Adults longitudinal study, including 1,222 individuals, aged 22-63 years and residing in Florianópolis, Santa Catarina State, Southern Brazil. Food consumption data was obtained from two 24-hour food recalls, and habitual consumption and prevalence rates of inadequate consumption of calcium, iron, zinc, and vitamins A, C, D, and E were estimated according to the Institute of Medicine and National Research Council guidelines. General obesity was defined based on the body mass index (BMI) values and abdominal obesity was based on waist circumference (WC) values. For most of the micronutrients investigated (calcium and vitamins A, C, D, and E), consumption levels were below the recommendations, with high prevalence of inadequate consumption in the sample as a whole. Only inadequate vitamin C intake was higher among obese individuals (general or abdominal). In addition, there was an inverse association between lower consumption of calcium and iron and higher BMI and WC, and between lower consumption of vitamins A and D and higher WC levels (ß = -0.92cm; 95%CI: -1.76; -0.08 and ß = -0.69 cm; 95%CI: -1.32; -0.06, respectively), especially in young adults. The study showed an inverse association between inadequate dietary consumption of micronutrients and general and abdominal obesity in a sample of adults in Southern Brazil.


O objetivo do estudo foi investigar a associação entre o consumo alimentar inadequado de micronutrientes e indicadores de obesidade geral e abdominal. Análise transversal, da segunda onda do estudo longitudinal EpiFloripa Adultos, incluindo 1.222 indivíduos de 22-63 anos, residentes em Florianópolis, Santa Catarina, Sul do Brasil. Os dados de consumo alimentar foram obtidos mediante aplicação de dois recordatórios de 24 horas, sendo o consumo habitual e as prevalências de inadequação no consumo de cálcio, ferro, zinco, e das vitaminas A, C, D e E estimadas conforme as recomendações do Instituto de Medicina e do Conselho Nacional de Pesquisa dos Estados Unidos. O estado nutricional de obesidade geral foi determinado considerando-se valores do índice de massa corporal (IMC), e a obesidade abdominal, considerando-se valores da circunferência da cintura (CC). Para a maioria dos micronutrientes investigados (cálcio, vitaminas A, C, D e E), as médias de consumo mostraram-se aquém dos valores recomendados, com prevalências elevadas de inadequação para toda a amostra. Somente a inadequação no consumo de vitamina C foi maior entre indivíduos obesos (geral ou abdominal). Além disso, associação inversa foi observada entre o menor consumo de cálcio e ferro com valores maiores do IMC e da CC, e entre o menor consumo das vitaminas A e D com valores maiores da CC (ß = -0,92cm; IC95%: -1,76; -0,08 e ß = -0,69cm; IC95%: -1,32; -0,06, respectivamente), principalmente entre adultos jovens. Foi possível identificar a existência de associação inversa entre o consumo alimentar inadequado de micronutrientes e o estado nutricional de obesidade geral e abdominal também em uma amostra de adultos residentes no Sul do Brasil.
