Cheilitis is a common inflammatory disorder of the vermillion and adjacent skin of the lips. A special type is angular cheilitis. The disease has a mixed etiology, mostly with bacterial and fungal components. Angular cheilitis may be a clinical sign of an underlying disease. It has two age peaks: one during childhood and another in adults. It becomes more frequent with aging. Clinical presentation, differential diagnoses, and treatment are discussed. Angular cheilitis is of importance in primary care of patients, in geriatrics, dentistry, pediatrics, internal medicine, and in dermatology., (© 2024.

Freshwater scarcity demands exploration of alternative resources like saline water and soils. Understanding the molecular mechanisms behind NaCl regulation in potential crop plants becomes increasingly important for promoting saline agriculture. This study investigated the euhalophyte Salicornia europaea , analyzing its gene expression, yield, and total phenolic compounds under hydroponic cultivation. We employed five salinity levels (0, 7.5, 15, 22.5, and 30 g/L NaCl) across five harvests at 15-day intervals, capturing plant development. Notably, this design deviated from conventional gene expression studies by recording organ-specific responses (shoots and roots) in plants adapted to long-term salinity treatments at various developmental stages. The highest fresh mass of S. europaea was observed four months after germination in 15 g/L NaCl. Identifying a reliable set of reference genes for normalizing gene expression data was crucial due to comparisons across shoots, roots, developmental stages, and salinity levels. A set of housekeeping genes - ubiquitin c ( SeUBC ), actin ( SeActin ) and dnaJ-like protein ( SeDNAJ ) - was identified for this purpose. Interestingly, plants grown without NaCl (0 g/L) displayed upregulation of certain genes associated with a NaCl deficiency related nutritional deprivation. These genes encode a tonoplast Na + /H + -antiporter ( SeNHX1) , a vacuolar H + -ATPase ( SeVHA-A ), two H + -PPases ( SeVP1 , SeVP2 ), a hkt1-like transporter ( SeHKT ), a vinorine synthase ( SeVinS ), a peroxidase ( SePerox ), and a plasma membrane Na + /H + -antiporter ( SeSOS1 ). Other genes encoding an amino acid permease ( SeAAP ) and a proline transporter ( SeProT ) demonstrated marginal or dispersing salinity influence, suggesting their nuanced regulation during plants development. Notably, osmoregulatory genes ( SeOsmP , SeProT ) were upregulated in mature plants, highlighting their role in salinity adaptation. This study reveals distinct regulatory mechanisms in S. europaea for coping with varying salinity levels. Identifying and understanding physiological reactions and sodium responsive key genes further elucidate the relationship between sodium tolerance and the obligate sodium requirement as a nutrient in euhalophytes., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Fussy and Papenbrock.)

Peroneal neuropathy, characterized by the occurrence of a foot drop, can develop due to a variety of factors, such as tumors, trauma, or metabolic conditions, making it one of the most prevalent peripheral neuropathies of the lower limbs. This condition is becoming more identifiable among patients who have undergone substantial weight reduction through bariatric surgery. The condition may present with symptoms like pain, sporadic paresthesia, and functional restrictions, primarily linked to foot drop. This case study explores an episode of acute foot drop in a patient who underwent a sleeve gastrectomy, leading to substantial weight loss.The patient, a middle-aged woman with a history of obesity, underwent sleeve gastrectomy and achieved normal body mass index (BMI) within a year. Eleven months post-surgery, she experienced a right-sided foot drop following a minor knee injury. Detailed history taking revealed noncompliance with vitamin supplementation, recurrent vomiting episodes, and a recent diagnosis of pancreatic insufficiency. Peripheral neuropathy, particularly peroneal nerve involvement, was confirmed through nerve conduction studies and radiological imaging. The mechanism of injury was attributed to rapid weight loss, potential nutrient deficiencies, and possible traction to the nerve.This case underscores the importance of early identification, comprehensive nutritional assessment, and timely intervention in managing neurological complications of post-bariatric surgery. Increased awareness among healthcare providers, particularly musculoskeletal specialists, is crucial as the prevalence of bariatric surgery continues to grow, ensuring optimal care for patients in this vulnerable population.

Purpose: Hyperemesis gravidarum has the potential to affect the long-term health of offspring. We examined whether maternal hyperemesis gravidarum was associated with the risk of hospitalization for childhood morbidity., Methods: We conducted a longitudinal cohort study of 1,189,000 children born in Quebec, Canada, between April 2006 and March 2021. The main exposure measure was maternal hyperemesis gravidarum requiring hospitalization in the first or second trimester. The outcome was any pediatric admission between birth and 16 years of age, with follow-up ending in March 2022. We used Cox regression models adjusted for maternal and socioeconomic factors to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association between maternal hyperemesis gravidarum and childhood hospitalization., Results: Among 1,189,000 children, 6904 (0.6%) were exposed to maternal hyperemesis gravidarum. Hospitalization rates at age 16 years were higher for children exposed to hyperemesis gravidarum than unexposed children (47.6 vs 43.9 per 100 children). Relative to no exposure, hyperemesis gravidarum was associated with a 1.21 times greater risk of any hospitalization before 16 years (95% CI 1.17-1.26). Hyperemesis gravidarum was associated with hospitalization for neurologic (HR 1.50, 95% CI 1.32-1.71), developmental (HR 1.51, 95% CI 1.29-1.76), digestive (HR 1.40, 95% CI 1.30-1.52), and allergic disorders (HR 1.39, 95% CI 1.24-1.56). When contrasted with preeclampsia, hyperemesis gravidarum was a stronger risk factor for these outcomes., Conclusions: Maternal hyperemesis gravidarum is associated with an increased risk of childhood hospitalization, especially for neurologic, developmental, digestive, and atopic disorders., What Is Known: • Hyperemesis gravidarum is associated with neurodevelopmental disorders in offspring. • However, the effect of hyperemesis gravidarum on other childhood morbidity is unclear., What Is New: • In this longitudinal cohort study of 1.2 million children, maternal hyperemesis gravidarum was associated with a greater risk of hospitalization before age 16 years. • Exposure to hyperemesis gravidarum was associated with developmental, neurologic, atopic, and digestive morbidity in childhood., (© 2024.

Copper is a trace element that plays an essential role in neurodevelopment and neurologic function. Acquired copper deficiency has a range of neurologic manifestations, with myelopathy being the most common association. We describe here the clinical, radiologic, histopathologic, and toxicologic findings of a rabbit with malnutrition, neurodegeneration, and suspected copper deficiency. A stray, adult female dwarf rabbit cross ( Oryctolagus cuniculus ) in poor body condition developed ataxia and pelvic limb weakness progressing to lateral recumbency and urine retention. The clinical findings suggested multifocal brainstem disease with right-sided central vestibular involvement; however, microscopic examination identified thoracic and lumbosacral spinal cord myelopathy. Differentials for the spinal cord changes included neurodegenerative disease, nutritional deficiency, neurotoxin, trauma to the lumbosacral region, and ischemia. Hepatic copper levels were suboptimal at 18 ppm dry weight (RI: 24-150 ppm dry weight). While speculative, copper-deficiency myelopathy is a treatable cause of non-compressive myelopathy that may occur in this species., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Advances in intensive care over the past few decades have significantly improved the chances of survival for patients with acute critical illness. However, this progress has also led to a growing population of patients who are dependent on intensive care therapies, including prolonged mechanical ventilation (PMV), after the initial acute period of critical illness. These patients are referred to as the "chronically critically ill" (CCI). CCI is a syndrome characterized by prolonged mechanical ventilation, myoneuropathies, neuroendocrine disorders, nutritional deficiencies, cognitive and psychiatric issues, and increased susceptibility to infections. It is associated with high morbidity and mortality as well as a significant increase in healthcare costs. In this article, we will review disease burden, outcomes, psychiatric effects, nutritional and ventilator weaning strategies as well as the role of palliative care for CCI with a specific focus on those requiring PMV., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Wernicke's encephalopathy (WE) is a rare, life-threatening condition in which thiamine deficiency causes dysfunction of the Kreb's cycle, accumulation of lactic acid in the brain tissues, and irreversible cognitive impairment. Prompt treatment with IV thiamine can reverse the process. The classic Wernicke's triad of ataxia, memory issues, and ocular abnormalities is not often present. Caine's criteria, which requires two of the following: dietary deficiencies, ocular abnormalities, altered cognition or mental status, and cerebellar dysfunction, is highly sensitive and specific for Wernicke's diagnosis, especially in patients with alcohol use disorder. Refeeding syndrome (RS) has similar risk factors to WE, including disease states that lead to malnutrition. Patients with RS develop WE due to thiamine depletion that occurs when oral nutrition is reinitiated after a period of poor oral intake. We present a patient with initially undetected WE who developed RS after the initiation of treatment with IV thiamine. RS prolonged the neurologic symptoms of WE and led to an extended hospital stay and significant physical debility. In our patient, WE preceded RS instead of occurring as a consequence of it. The case highlights that if one of these disorders is present, the other may not be far behind. When WE precedes RS, prolonged treatment with IV thiamine may be warranted until the symptoms of both disorders resolve., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Neuro-ophthalmic manifestations of Wernicke encephalopathy (WE) are uncommon and vary from nystagmus, oculomotor palsies, anisocoria, and optic disc edema to vision loss. We describe a case of a 53-year-old woman presenting with subacute bilateral painless vision decline, lower-extremities weakness with impaired ambulation, headache, and abdominal pain. Neurological examination was pertinent for confabulation, bilateral decreased visual acuity with an absent blink to threat, absent afferent pupillary defect and fundus abnormalities, and significant allodynia in bilateral lower extremities. Besides elevated inflammatory marker with an erythrocyte sedimentation rate (ESR) of 130 mm/hr, her infectious, autoimmune, paraneoplastic, and neuromyelitis optica work-up was overall unremarkable. Brain MRI showed abnormal fluid-attenuated inversion recovery (FLAIR) signaling in bilateral mammillary bodies and around periaqueductal gray matter concerning WE. Due to concerns of Wernicke-Korsakoff syndrome (WKS), parenteral high-dose thiamine was initiated with significant clinical improvement. The patient was also later found to have a positive anti-myelin oligodendrocyte glycoprotein (MOG) antibody, which was deemed false positive given the atypical phenotype and symptomatic improvement with thiamine supplementation. This case encourages the consideration of vision loss as a manifestation of WKS, especially in patients who have risk factors. Testing serum levels of thiamine is strongly encouraged; however, initiating empiric treatment is advocated for high clinical suspicion due to its reversible nature and minimal risk for side effects., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background: Solid pediatric tumors refer to cancers that affect children and adoles-cents, and they present unique challenges due to their distinct biological characteristics and their vulnerability to young patients. This study aims to shed light on addressing anemia and the causes of anemia in patients with solid pediatric tumors., Materials and Methods: This retrospective cohort comprised 200 healthy children as controls and 235 patients with solid tumors. The study was conducted at first Affiliated Hospital of Zhengzhou University between January 2020 and June 2023. We evaluated different parameters of blood components in controls and patients with solid tumors such as medulloblastoma, neuroblastoma, rhabdomyosarcoma, germ cell tumors, hepatoblastoma and nephroblastoma before and patients with only these tumors 3 weeks after the first cycle of chemotherapy. Further, we evaluated the relationship between serum ferritin and the weight of patients and assessed the relationship be-tween anemia and metastasis to the bone marrow in patients with neuroblastoma and hepatoblas-toma., Results: We observed various combinations of derangements in blood parameters such as hemo-globin, red blood cells, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscu-lar hemoglobin concentration, hematocrit, red cell distribution width, white blood cells, and plate-let in medulloblastoma, neuroblastoma, rhabdomyosarcoma, germ cell tumors, hepatoblastoma and nephroblastoma before and 3 weeks after first cycle of chemotherapy. We found a significant correlation between serum ferritin levels and weight in neuroblastoma patients who are ≤ 2 years (p = 0.022). Involvement of tumor cells in bone marrow correlates with decreased Hb levels in both neuroblastoma (CI = 93.21-106.68, p = 0.001) and hepatoblastoma (CI = 113.36-121.00, p = 0.001)., Conclusion: Anemia may manifest as an early symptom in neuroblastoma, hepatoblastoma, and nephroblastoma. Also, anemia may be worse in patients with neuroblastoma and hepatoblastoma after chemotherapy and might warrant anemia therapy., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background: Nutritional disorders of phosphorus (P), due to deficiency or toxicity, reduce the development of Eucalyptus spp. seedlings. Phosphorus deficiency often results in stunted growth and reduced vigor, while phosphorus toxicity can lead to nutrient imbalances and decreased physiological function. These sensitivities highlight the need for precise management of P levels in cultivation practices. The use of the beneficial element silicon (Si) has shown promising results under nutritional stress; nevertheless, comprehensive studies on its effects on Eucalyptus spp. seedlings are still emerging. To further elucidate the role of Si under varying P conditions, an experiment was conducted with clonal seedlings of a hybrid Eucalyptus spp. (Eucalyptus grandis × Eucalyptus urophylla, A207) in a soilless cultivation system. Seedlings were propagated using the minicutting method in vermiculite-filled tubes, followed by treatment with a nutrient solution at three P concentrations: a deficient dose (0.1 mM), an adequate dose (1.0 mM) and an excessive dose (10 mM), with and without the addition of Si (2mM). This study assessed P and Si concentration, nutritional efficiency, oxidative metabolism, photosynthetic parameters, and dry matter production., Results: Si supply increased phenolic compounds production and reduced electrolyte leakage in seedlings provided with 0.1 mM of P. On the other hand, Si favored quantum efficiency of photosystem II as well as chlorophyll a content in seedlings supplemented with 10 mM of P. In general, Si attenuates P nutritional disorder by reducing the oxidative stress, favoring the non-enzymatic antioxidant system and photosynthetic parameters in seedlings of Eucalyptus grandis × Eucalyptus urophylla., Conclusion: The results of this study indicate that Eucalyptus grandis × Eucalyptus urophylla seedlings are sensitive to P deficiency and toxicity and Si has shown a beneficial effect, attenuating P nutritional disorder by reducing the oxidative stress, favoring the non-enzymatic antioxidant system and photosynthetic parameters., (© 2024.

Scurvy, a condition caused by vitamin C deficiency, is characterized by a syndrome of multisystem disorder due to defective collagen production and antioxidative function. This condition is infrequent in this modern era; thus, it is often not within the list of differential diagnoses. The broad clinical picture is generally overlooked as other systemic illnesses, resulting in an extensive investigation that delays the diagnosis. Herein, we report a case of an 8-year-old boy with underlying autism spectrum disorder who presented with lower limb pain and other constitutional symptoms. Examination revealed multiple hyperpigmented scars over the upper and lower limbs and gingival hyperpigmentation. With history of picky eating habits and clinical symptoms supported by radiographic findings, scurvy was suspected and subsequently confirmed based on a low level of ascorbic acid. With vitamin C supplementation and proper nutritional support, the patient recovered well., Competing Interests: We have no conflicts of interest to disclose., (© Academy of Family Physicians of Malaysia.)

Vitamin deficiencies, especially after Bariatric surgery, are common and, when not properly addressed, can lead to debilitating complications. Bariatric procedures, to variable degrees, alter the anatomy and physiology of the gastrointestinal; this alteration makes these patients more susceptible to developing nutritional deficiencies. Peripheral neuropathy is one of the complications that can arise from nutritional deficiencies, and it can cause severe functional impairment. Vision loss is a relatively uncommon complication after weight loss procedure. Changes in the retinal nerve fiber layer, choroidal thickness, and visual fields due to hypovitaminosis result in nutritional optic neuropathy and retinopathy. The main retinal complication is nyctalopia (night blindness), which is caused by vitamin A deficiency. We present a case of concomitant peripheral neuropathy and vision loss secondary to reduced levels of multiple vitamins following gastric bypass surgery. This case highlights the need for regular vitamin level monitoring and appropriate replenishment in patients after bariatric surgery to prevent significant morbidities., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Khalid et al.)

Background Special needs children have various health problems, and the most common problems are nutritional deficiency and malnourishment which leads to increased morbidity affecting their quality of life. This study aims to assess the nutritional status and health-seeking behaviour of special needs children. Methods The study was conducted among 46 special needs children at a special needs children's home. After collecting basic sociodemographic details, they were assessed for nutritional status and health-seeking behaviour using a semi-structured questionnaire followed by general and clinical examination. Results Out of these 46 special needs children, 69.6% were male and 30.4% were female. The mean age was 11.69±4.62 years. In this study, 65.22% were underweight; 6.52% were overweight; 10.87% were obese I; 4.35% were obese III; 13.04% were normal. Among them, 37% seek Government healthcare facilities for their healthcare needs. Referral advice was provided to all required children. Conclusion A high proportion of the special needs children were screened positive for nutritional deficiency and malnourishment which needs to be addressed. Interventions should be aimed at correcting the nutritional deficiency and malnourishment by involving the caretakers, mainly mothers of these children., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, K S et al.)

Background: Malnutrition is a major health concern among children especially in low and middle-income countries. However, there are limited studies on school health in Bangladesh. This study aimed to reduce malnutrition among primary school children in Bangladesh by increasing awareness and knowledge through school nurse-led health education., Methods and Materials: A prospective, open-label, parallel-group (1:1), cluster nonrandomized controlled trial on primary school children conducted in rural Bangladesh. The study lasted 13 months between September 2021 and September 2022. Four schools were selected and assigned to the intervention and control groups (CGs). Next, school nurses provided evidence-based health education to the children in the intervention group (IG) for 9 months to improve awareness and knowledge of malnutrition. Data were collected at baseline, midline, and endline., Results: Overall, 604 children were enrolled at the baseline; among them, 455 (CG, n = 220; IG, n = 235) completed the study. Changes in the malnutrition rate-the primary outcome-were not significant ( P = 0.225). However, after adjusting the endline data with baseline and sociodemographic data, the children's body mass index improved significantly in the IG than in the CG ( P < 0.05). Changes in eating behavior, and awareness and knowledge of malnutrition-the secondary outcomes-significantly differed between the groups ( P < 0.001)., Conclusion: The school nurse-led health education program significantly improved primary school children's awareness and knowledge of malnutrition. This study revealed the effectiveness of school nurses in reducing malnutrition among children, which may decrease future morbidity and mortality rates in children., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Family Medicine and Primary Care.)

Background: Bariatric surgery has been associated with numerous micronutrient deficiencies. Several observational studies have found that these deficiencies are more common in racially/ethnically minoritized patients., Objectives: To conduct a systematic review to investigate whether racially/ethnically minoritized patients experience worse nutritional outcomes after bariatric surgery., Setting: University of Wisconsin-Madison., Methods: PubMed, CINAHL, PsychINFO, and Cochrane databases were queried. We searched for manuscripts that reported micronutrient levels or conditions related to micronutrient deficiencies according to race/ethnicity (White, African American/Black, and Hispanic) after laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass between 2002 and 2022. Eleven micronutrients (vitamins A, B1 [thiamine], B12, D, E, K, calcium, copper, folate, iron, and zinc), and four conditions (anemia, bone loss, fractures, and hyperparathyroidism) were assessed., Results: Abstracts from 953 manuscripts were screened; 18 full-text manuscripts were reviewed for eligibility, and ten met the inclusion criteria. Compared to White patients, African Americans had a higher prevalence of thiamine, vitamin D, and vitamin A deficiencies. There were no differences in calcium and vitamin B12 deficiencies. The other six micronutrients were not assessed according to race/ethnicity. Hyperparathyroidism was more prevalent in African Americans than White patients in the three studies that evaluated it. The prevalence of fractures was mixed. Anemia and bone loss were not evaluated according to race/ethnicity., Conclusions: Although the literature on micronutrient outcomes following bariatric surgery according to race/ethnicity is limited, African Americans appear to experience a higher prevalence of vitamin deficiencies and associated conditions. Qualitative and quantitative research to explore these disparities is warranted., (Published by Elsevier Inc.)

Background: To assess the state and trends of global nutrition, our best tools are nationally representative assessments using human biomarker assays, yet these are expensive and logistically challenging. We instead often rely on more easily produced global nutrient datasets-measures of nutrients provided by the diet-as a proxy for nutritional intake and deficiency, due to their greater geographic and temporal coverage. However, the accuracy of global nutrient datasets is questionable., Objective: We aimed to test whether estimates of inadequate dietary intake derived from existing global nutrient datasets reliably associate with biophysical deficiency., Design: We performed linear regressions of estimates of inadequate dietary nutrient intake derived from three global nutrient datasets-Global Dietary Database, Global Nutrient Database, and Global Expanded Nutrient Supply (GENuS) model-against the existing suite of nationally representative biomarker survey data for three key nutrients of global concern in two vulnerable demographic groups: zinc, folate, and vitamin A in females of childbearing age; and zinc and vitamin A in children younger than 5 y., Results: We found significant associations (P < 0.1) for only 3 of 22 regressions between global nutrition datasets and biophysical deficiency: zinc for females of childbearing age from GENuS and Global Dietary Database, and zinc for children under 5 y from GENuS. Folate and vitamin A show no reliable relationship between nutrient datasets and independent biomarker surveys. Applying the successful models for zinc to the accompanying full datasets yield estimates of global zinc deficiency of 31%-37% for these demographic groups., Conclusions: We found that few estimates of nutritional inadequacy from global dietary datasets are associated with more direct measures of biophysical deficiency from biomarker studies. Researchers and policymakers must be cautious when applying global nutrient datasets to questions of global health and use them for limited applications., (Copyright © 2023 The Author(s).

Severe malnutrition following one-anastomosis gastric bypass (OAGB) remains a concern. Fifty studies involving 49,991 patients were included in this review. In-hospital treatment for severe malnutrition was needed for 0.9% (n = 446) of patients. Biliopancreatic limb (BPL) length was 150 cm in five (1.1%) patients, > 150 cm in 151 (33.9%), and not reported in 290 (65%) patients. OAGB was revised to normal anatomy in 126 (28.2%), sleeve gastrectomy in 46 (10.3%), Roux-en-Y gastric bypass in 41 (9.2%), and shortening of BPL length in 17 (3.8%) patients. One hundred fifty-one (33.8%) patients responded to treatment; ten (2.2%) did not respond and was not reported in 285 (63.9%) patients. Eight (0.02%) deaths were reported. Standardisation of the OAGB technique along with robust prospective data collection is required to understand this serious problem., (© 2023.

Introduction: Rice heavily relies on nitrogen fertilizers, posing environmental, resource, and geopolitical challenges. This study explores sustainable alternatives like animal manure and remote sensing for resource-efficient rice cultivation. It aims to assess the long-term impact of organic fertilization and remote sensing monitoring on agronomic traits, yield, and nutrition., Methods: A six-year experiment in rice fields evaluated fertilization strategies, including pig slurry (PS) and chicken manure (CM) with mineral fertilizers (MIN), MIN-only, and zero-fertilization. Traits, yield, spectral responses, and nutrient content were measured. Sentinel-2 remote sensing tracked crop development., Results: Cost-effective organic fertilizers (PS and CM) caused a 13% and 15% yield reduction but still doubled zero-fertilization yield. PS reduced nitrogen leaching. Heavy metals in rice grains were present at safe amounts. Organic-fertilized crops showed nitrogen deficiency at the late vegetative stages, affecting yield. Sentinel-2 detected nutrient deficiencies through NDVI., Discussion: Organic fertilizers, especially PS, reduce nitrogen loss, benefiting the environment. However, they come with yield trade-offs and nutrient management challenges that can be managed and balanced with reduced additional mineral applications. Sentinel-2 remote sensing helps manage nutrient deficiencies. In summary, this research favors cost-effective organic fertilizers with improved nutrient management for sustainable rice production., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Marti-Jerez, Català-Forner, Tomàs, Murillo, Ortiz, Sánchez-Torres, Vitali and Lopes.)

Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy characterized by simple operation and few postoperative complications have gradually become the two most commonly used surgical methods in clinical practice.A series of complications often occur after bariatric surgery,including gallstone disease,anemia,malnutrition,gastroesophageal reflux disease,kidney stones,and birth defects in offspring of women of childbearing age.There are controversies regarding the causes and countermeasures of these complications.This article mainly reviews the risk factors and countermeasures for the complications after bariatric surgery.

Background: Bariatric surgery (BS) can lead to postoperative nutritional deficiencies (NDs) due to restrictive and malabsorptive mechanisms, but there is limited literature quantifying NDs' prevalence over time and their predictors among patients undergoing BS., Objective: To characterize time trends and predictors of postoperative NDs., Setting: This retrospective cohort study used the U.S. IBM MarketScan commercial claims database (2005-2019) to include adults who underwent BS with continuous enrollment., Methods: BS included Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), adjustable gastric band (AGB), and biliopancreatic diversion with duodenal switch. NDs included protein malnutrition, deficiencies in vitamins D and B12, and anemia that may be related to NDs. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of NDs across BS types after adjusting for other patient factors., Results: Within 83,635 patients (mean age [SD], 44.5 [9.5] yr; 78% female patients), 38.7%, 32.9%, and 28% underwent RYGB, SG, and AGB, respectively. Age-adjusted prevalence of any NDs within 1, 2, and 3 years after BS ranged from 23%, 34%, and 42%, respectively (in 2006) to 44%, 54%, and 61%, respectively (in 2016). Relative to the AGB group, the adjusted OR of any 3-year postoperative NDs was 3.00 (95% CI, 2.89-3.11) for the RYGB group and 2.42 (95% CI, 2.33-2.51) for the SG group., Conclusions: RYGB and SG were associated with 2.4- to 3.0-fold odds of developing 3-year postoperative NDs compared with AGB, independent of baseline ND status. Pre- and postoperative nutritional assessments are recommended for all patients undergoing BS to optimize postoperative outcomes., (Copyright © 2023 American Society for Metabolic and Bariatric Surgery.

Humans are constantly facing multiple health challenges from both communicable and non-communicable diseases that significantly affect their health. Additionally, drug resistance or failure has made the situation even worse and poses serious challenges for researchers to develop new drugs. Hence, to address these problems, there is an urgent need to discover and develop timely and long-term-based therapeutic treatments from different sources. One such approach is harnessing the potential of plant secondary metabolites. Plants have been utilized for therapeutic purposes in addition to being used for nutritional benefits. In the last two decades, plant-based drug developments have been one of the effective means of treating human diseases owing to their multiple functions. More recently, anti-nutritional factors (ANFs) have emerged as one of the important targets for novel plant-based drug development due to their multifaceted and potential pharmacological properties. However, their anti-nutritional properties have been the major setback for their limited success in the pharmacological sector. In this review, we provide an overview of ANFs and their beneficial roles in preventing human diseases with multiple case studies. We also highlight the recent developments and applications of ANFs in the food industry, agriculture, and pharmaceutics with future perspectives. Furthermore, we evaluate meta-analyses on ANFs from the last 30 years in relation to their function in human health benefits. This review is an endeavor to reevaluate the merit of these natural compounds and explore their potential for both human and animal health., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Salim, Nehvi, Mir, Tyagi, Ali and Bhat.)

Introduction: Nutritional vitamin B12 deficiency has been shown to cause Infantile epileptic spasms syndrome (IESS) in infants in anecdotal studies., Methods: In this retrospective cohort study, we intended to study the clinical presentation, neurophysiological, laboratory abnormalities, treatment, and neurodevelopmental outcome at 6-months in infants presenting with IESS secondary to nutritional vitamin B12 deficiency (NVBD) and to compare these variables from the rest of the infants with IESS without vitamin B12 deficiency. We included only spasm-free cases or those who showed at least a 50% reduction in spasm frequency on D7 after starting oral/parenteral vitamin B12. We used well-validated measurement tools like the Developmental Assessment Scale for Indian Infants (DASII), Child Feeding Index (CFI), Burden of amplitudes and epileptiform discharges (BASED) score, countable Hypsarrhythmia paroxysm index (cHPI), durational Hypsarrhythmia paroxysm index (dHPI), and Early childhood epilepsy severity scale (E-CHESS) score for documenting these variables., Results: Data from 162 infants with IESS (21 caused by NVBD) were included in our study. The NVBD group had more patients residing in the rural region, with lower socioeconomic status, vegetarian mothers and poor complementary feeding index (p<0.001 for all). The NVBD group also had less number of patients requiring antiseizure medications (ASMs) and hormonal therapy(p<0.001), remained seizure free at six months (p=0.008), lower number of clusters per day (p=0.02) and the number of spasms per clusters at presentation (p=0.03), lower BASED score (p=0.03) and cHPI, dHPI at presentation (p<0.001). All of them remained spasm-free, with normal electroencephalogram at 6-months. Development quotient at baseline, at 6-months, and improvement in development quotient between these two-time points were more in the vitamin B12 deficiency group (p<0.001). All of them had clinical features of pre-ITS (infantile tremor syndrome) or ITS and it was found to be the only independent predictor of NVBD in infants with IESS. Mothers of all these infants had low serum vitamin B12 levels (<200 pg/ml)., Conclusions: Nutritional vitamin B12 deficiency may cause IESS in infants. Hence, vitamin B12 deficiency needs to be ruled out in patients with IESS without any definite etiology., Competing Interests: Declaration of Competing Interest None, (Copyright © 2023 British Epilepsy Association.

Beef cattle are less prone to metabolic diseases as compared with dairy cattle; however, there are disease entities of concern in feedlot and cow-calf beef cattle operations. In one study, a prevalence of 2% was found for ruminant acidosis in a feedlot; however, there is little prevalence information published with regard to metabolic diseases in beef cattle.1 Metabolic diseases covered in this article are hypomagnesemia, ruminal acidosis, and all of the common sequelae, polioencephalomalacia, manganese deficiency, and protein-energy malnutrition (PEM)., (Copyright © 2023 Elsevier Inc.

Root hairs tie the root system to the soil substrate, facilitate water and nutrient absorption, and enable the interaction with microbes in the soil. Root hair development can be classified into three main development types (I-III). Root hair development type III has been extensively studied, mainly represented using the model plant Arabidopsis thaliana . Transcription factors, plant hormones, and proteins are involved at different root hair developmental stages. The mechanisms underlying development in types I and II have been examined using other representative plant species but have not been studied as intensively. Many key developmental genes in types I and II are highly homologous with those in type III, exhibiting conservation of related mechanisms. Root hairs are also involved in the regulation of plant response to abiotic stress by altering developmental patterns. Abiotic stress, regulatory genes, and plant hormones jointly regulate root hair development and growth; however, few studies have focused on how root hair recognizes abiotic stress signals. This review examines the molecular mechanisms of root hair development and adaptations under stress, and prospective future developments in root hair research are also discussed.

Objective: The macromorphological characteristics and frequency of endocranial abnormal blood vessel impressions (ABVI) and periosteal appositions of dura mater (PADM), and their association with sex, age-at-death and scurvy-like lesions were studied. The possible etiologies of these lesions were discussed., Materials: A total of 144 adult skulls excavated from an early modern (16th-19th c. CE) cemetery at the Czysty Square in Wrocław (Poland) were examined, most of which were intact., Methods: The endocranial surface was inspected with an endoscope for the presence, location, and severity of ABVI and PADM. Frequencies of ABVI and PADM were grouped by sex and age-at-death., Results: A little more than a half (53.5 %) of the examined skulls were affected by ABVI and/or PADM. PADM were more frequent in females. However, both alteration types occurred with similar frequencies across all age-at-death categories., Conclusions: The high frequency of ABVI and PADM suggests that meningeal infections and/or hemorrhage among inhabitants of early modern Wrocław, especially in females, were common., Significance: The paper emphasizes the need for using an endoscope in standard anthropological analysis of intact skulls, as it allows for a nondestructive inspection of the endocranial surface., Limitations: The endoscope did not allow for an accurate examination of the middle cranial fossa., Suggestions for Further Research: Comparative studies with other historical populations are necessary to better understand the possible etiologies of macromorphological and demographic characteristics of ABVI and PADM., Competing Interests: Declarations of interest None., (Copyright © 2023 Elsevier Inc.

Introduction The majority of nail diseases in children are comparable to those in adults, while there are some physiological changes that start to happen around this age and go away over a few years. These conditions could be symptoms of infections and systemic illnesses. Pediatric nail disorders are typically easy to diagnose clinically, although there are occasionally conditions that masquerade as juvenile nail problems. Dermoscopy has grown in favour as a rapid, easy, non-invasive clinical procedure for examining nail diseases. This study aims to assess dermoscopic findings of child nail diseases. Methods A prospective analysis was conducted for seven months between January and July, 2022, at PNS Shifa Hospital, Karachi, Pakistan. A total of 180 patients who presented in the outpatient department with any dermatological complaint underwent thorough history and examination. Special emphasis was given to clinical and dermoscopic examinations of nails. Data analysis enclosed descriptive and inferential statistics. The quantitative data was presented with help of mean and standard deviation, while the qualitative data was presented with help of frequency and percentage tables. Chi-square test was applied to compare nail findings diagnosed on clinical examination and dermoscopic examination. Results The mean age of study subjects was 9.4±3.2 years and ranged between five years and 18 years. The most common nail changes were hand eczema (n=41, 23%) followed by nail changes due to nutritional disorders (n=38, 21%), anaemia (n=34, 19%) and habit tic deformity (n=31, 17.2%). Conclusions Clinical evaluation is crucial for nail disease diagnosis. Dermoscopy of nails can help with the final diagnosis of nail disease and confirm clinical diagnoses. Also, it aids in the management of nail illnesses by providing a clearer picture of pathology and nail structure., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Zahoor et al.)

Iron deficiency is a public health problem with devastating health, developmental and behavioral effects which often exacerbated due to affordability and access to screening and diagnosis. Using IronScan ™ a portable, point-of-care diagnostic system capable of quantitatively measuring ferritin in blood, we validated IronScan™ ferritin measurements using whole blood and serum with a lab-based, regulator-approved analytical device for measuring ferritin in venous serum. Capillary (finger stick) and venous whole blood samples were obtained from 44 male and female volunteers. Venous serum (vSer) ferritin concentrations were measured on Immulite 2000 Xpi (gold standard). Capillary whole blood (cWB), venous whole blood (vWB), and vSer ferritin levels were measured by IronScan™ . cWB ferritin concentrations from IronScan™ were significantly correlated (R 2 = 0.86) with vSer measured with the FDA-approved Immulite system. The results from the multiple regression analysis indicate that 10% of the variability was due to the method of blood collection (venous vs. capillary) and 6% was due to the form of blood analysis (whole blood vs. serum). The sensitivity of diagnosing iron deficiency using the WHO cutoff of <30 ng/mL is 90%, with a specificity of 96%. In conclusion, IronScan™ is a rapid viable option for measuring ferritin as a point-of-care system.

Immune suppression in elderly individuals is one of the most important hygienic problems in aged societies. The primary immune organ thymus is histologically and functionally reduced by aging, which is known as thymic involution. The thymus is also involuted by nutritional deficiency, which frequently occurs in elderly individuals. However, there is no information on the thymic changes caused by nutritional deficiency with aging. Therefore, this study was conducted to examine the histological and molecular responses of the thymus to nutritional deficiency in young and aged mice. The thymic size was significantly smaller in 16- or 18-week-old aged mice than in 7-week-old young mice. Dietary restriction for 48 h reduced the thymic size in young mice, but not in aged mice. Immunostaining with anti-keratin 5 antibody revealed that the integrity of the corticomedullary boundary was maintained in the aged thymus, whereas dietary restriction induced its disorganization in both young and aged thymus. The numbers of immunoglobulin G (IgG)-positive cells were increased upon dietary restriction in aged, but not in young, thymus. Dietary restriction, but not aging, upregulated the mRNA levels of T-helper 2 (Th2)-related Il5, Il6, and Il10, whereas aging increased that of Th1-related interferon-γ (Ifng). The dietary restriction-induced upregulation of prostanoid-synthesizing enzymes was clearly observed in the young thymus but attenuated in the aged thymus. Thus, nutritional deficiency and aging cause an involuted thymus with different properties. Moreover, the thymus in aged mice does not show further reduction in size by nutritional deficiency but still responds differently compared with that in young mice.

Background: Osteoporosis may result from risk factors such as smoking, alcohol, low body mass index, less physical exercise, and dietary calcium deficiency. The risk of osteoporosis fractures can be reduced with lifestyle changes, which include diet, exercise, and preventing falls. The present study is an effort to measure the burden of risk factors of osteoporosis in adult male soldiers in the Armed Forces., Methods: The present study was a cross-sectional study among serving soldiers in South-Western part of India, and 400 participants consented to be included in the study. After obtaining informed consent, the questionnaire was distributed. Venous blood samples were collected to measure serum calcium, phosphorus, vitamin D, and parathyroid hormone (PTH)., Results: The prevalence of vitamin D3 severe deficiency (<10 ng/mL) was 38.5%, and the prevalence of vitamin D3 deficiency (10-19 ng/mL) was 33%. Low serum calcium (<8.4 mg/dL) and serum phosphorus (<2.5 mg/dL) were found among 19.5% and 11.5%, respectively, whereas a raised serum PTH level (>66.5 pg/mL) was seen in 5.5% of the participants. A statistically significant association was found between consumption of milk and milk products and levels of calcium. With a cutoff value of 20 ng/mL for vitamin D3 deficiency, a statistically significant association was found for consumption of fish, physical activity, and sun exposure., Conclusion: A remarkably large percentage of otherwise normal healthy soldiers have deficiency or insufficiency of vitamin D and might be prone to osteoporosis. Despite significant advances in our understanding and management options for male osteoporosis, there still remain important gaps in knowledge which needs to be looked into., Competing Interests: The authors have none to declare., (© 2021 Director General, Armed Forces Medical Services.

Climate change brings exposures to heat, air pollution, poorer quality food, and infectious disease that have significant direct effects on women and their mental health. These environmental impacts are multifaceted in their consequences and raise risks of depression, suicide, violent victimization, post-traumatic stress disorder, and various other neuropsychiatric symptoms. Women also suffer increased climate psychological risks from higher rates of stillbirth, preterm birth, and developmental problems in their children. Here we review what is known about the overlap of women's individual mental health and climate change, and highlight areas where more research is needed., (© 2022 International Federation of Gynecology and Obstetrics.)

Background & Aims: We aimed to estimate the prevalence of the inadequate intake and status of magnesium, zinc, and vitamins A, C, E, and D and identify factors associated with micronutrient deficiency in serum/plasma among residents of São Paulo, Brazil., Methods: Data from 824 individuals aged ≥14 years were obtained from the 2015 ISA-Nutrition, a population-based, cross-sectional survey. Dietary and supplement intakes were assessed using two 24-h dietary recalls, and the micronutrient inadequacies were estimated using the National Cancer Institute method. Micronutrient status was measured in serum or plasma, and deficiency was established according to the lower limit of the reference values. Receiver operating characteristic curve analysis was used to identify the effect of intake on the micronutrient status in serum/plasma. Logistic regression analysis was applied to assess the association between micronutrient status and individual characteristics., Results: More than 80% of the population had an inadequate dietary intake of magnesium, vitamin E, and vitamin D. Males had a high prevalence of inadequate dietary intake of vitamin A and zinc. A high-to-moderate prevalence of inadequate vitamin C intake was observed. Vitamin D was the only nutrient with a deficient status comparable to its dietary inadequacy. The other nutrients demonstrated a lower deficiency prevalence compared to dietary inadequacy, and vitamin A demonstrated the lowest prevalence of deficiency in plasma. Generally, dietary intake showed a non-notable association with micronutrient deficiency in serum/plasma. Individuals with fasting glucose concentrations ≥100 mg/dL and those using diuretic drugs had a higher risk of serum magnesium deficiency. Those using lipid-lowering drugs and those with high plasma adiponectin concentrations had a higher risk of serum zinc deficiency. Individuals who smoked and those with hypertension showed a higher risk of plasma vitamin C deficiency. Individuals with average leptin concentrations had a higher risk of plasma vitamin E deficiency. Finally, those with sufficient leisure-time physical activity had a lower risk of serum vitamin D deficiency., Conclusions: Residents of the urban areas of São Paulo demonstrated substantially inadequate intakes of most of the assessed micronutrients; however, micronutrient deficiency in serum/plasma was not associated with dietary inadequacy, and it usually demonstrated a lower prevalence than dietary indicators. Thus, using micronutrient intake to determine the serum/plasma profile should be done with caution. The status of the micronutrients varied according to individual characteristics, indicating the interplay of complex mechanisms underlying micronutrient balance., Competing Interests: Conflict of interest All authors declare no conflicts of interest that could inappropriately influence this article., (Copyright © 2022 European Society for Clinical Nutrition and Metabolism.

Introduction: Single Anastomosis Duodenal-Ileal Bypass with Sleeve Gastrectomy (SADI-S), like other hypoabsorptive procedures, could be burdened by long-term nutritional deficiencies such as malnutrition, anemia, hypocalcemia, and hyperparathyroidism., Objectives: We aimed to report our experience in terms of mid-term (2 years) bariatric, nutritional, and metabolic results in patients who underwent SADI-S both as a primary or revisional procedure., Methods: One hundred twenty-one patients were scheduled for SADI-S as a primary or revisional procedure from July 2016 to February 2020 and completed at least 2 years of follow-up. Demographic features, bariatric, nutritional, and metabolic results were analyzed during a stepped follow-up at 3 months, 6 months, 1 year and 2 years., Results: Sixty-six patients (47 female and 19 male) were included. The median preoperative BMI was 53 (48-58) kg/m 2 . Comorbidities were reported in 48 (72.7%) patients. At 2 years, patients had a median BMI of 27 (27-31) kg/m 2 ( p < 0.001) with a median %EWL of 85.3% (72.1-96.1), a TWL of 75 (49-100) kg, and a %TWL of 50.9% (40.7-56.9). The complete remission rate was 87.5% for type 2 diabetes mellitus, 83.3% for obstructive sleep apnea syndrome and 64.5% for hypertension. The main nutritional deficiencies post SADI-S were vitamin D (31.82%) and folic acid deficiencies (9.09%)., Conclusion: SADI-S could be considered as an efficient and safe procedure with regard to nutritional status, at least in mid-term (2 years) results. It represents a promising bariatric procedure because of the excellent metabolic and bariatric outcomes with acceptable nutritional deficiency rates. Nevertheless, larger studies with longer follow-ups are necessary to draw definitive conclusions.

Background: Vitamin B deficiencies are involved with several outcomes in fertility and pregnancy. In Brazil, the national prevalence rates of these micronutrient deficiencies in women of reproductive age were not known. This study aims to systematically identify, select, evaluate, analyze, and report the prevalence rates of vitamin B complex deficiencies in women of reproductive age in Brazil and identify variables that may modify the outcome rates., Methods: A systematic review will be conducted guided by the following question: "What is the prevalence of vitamin B deficiencies in women of reproductive age in Brazil?". The studies will be identified and selected from a literature search using electronic databases, consultation with researchers/specialists, and reference lists of eligible studies and reviews on the topic. Major eligibility criteria include observational cross-sectional and cohort studies carried out in Brazil and performed in women 10-49 years old, or pregnant and lactating mothers, and investigated the deficiency of vitamin B complex by laboratory test. Two reviewers independently will perform the screening and selection of the studies, data extraction, and risk of bias assessment. For the data report, a narrative approach will be used to present the characteristics of the included studies and individual findings. A random meta-analysis model will be implemented to summarize the individual prevalence rates in a global value if the studies are sufficiently homogeneous., Discussion: This study aims to identify the national and regional prevalence rates of vitamin B complex deficiencies in women of reproductive age; allow the policymakers discuss, plan, and implement public policies to screen; and prevent and/or treat these malnutrition conditions. This also aims to know the rates of nutritional deficiencies over the years, serving as an indirect indicator of the socioeconomic and dietary patterns of the population. Specifically for folate, this study allows to compare the prevalence rates of deficiency of this vitamin before and after the mandatory fortification of wheat and corn flours implemented since 2004 in Brazil, in this specific population. The evidence gathered may highlight the need for population-based studies to investigate the deficiency of these vitamins., Systematic Review Registration: PROSPERO CRD42020188474., (© 2023.

Vitamin C deficiency resulting in scurvy, is considered to be a rare nutritional disorder in developed countries, thus leading to underdiagnosis with exposure to unnecessary investigations and delay in appropriate treatment. The wide myriad of clinical signs and symptoms with which vitamin C deficiency can present (including haematological, musculoskeletal and vague constitutional symptoms that overlap with other common medical conditions), also contributes to this diagnostic challenge. Despite scurvy being habitually thought to be present in children with neurodevelopmental conditions such as autism spectrum disorder, other important at-risk groups that frequently tend to be forgotten include children with persistent fussy eating behaviour, and children with abnormal vitamin C metabolism. We hereunder present a case of a 10-year-old boy who presented to an acute general hospital for further investigation with gait disturbance. The lack of detailed nutritional assessment on presentation in the first instance led to a missed diagnosis of vitamin C deficiency, thus exposing the child to a wide array of unnecessary investigations and treatments. The added perplexity to the case resulting from false positive results of investigations performed as part of this child's workup, is also discussed.

Background: Tuberculosis (TB) and malnutrition are major global health problems, with multidrug-resistant (MDR) TB complicating international efforts. The role of vitamin D in susceptibility to and as an adjunctive treatment for TB is being studied extensively, although no study has included MDR-TB patients in context to dietary profile with vitamin D levels and sunlight exposure. Objective: This study aimed to estimate vitamin D serum levels and examine their association with dietary intake of vitamin D and sun exposure in patients with MDR-TB. Methods: North Indian participants were enrolled in three groups: MDR-TB, drug-susceptible pulmonary TB (DS-PTB), and healthy controls. All consenting participants underwent the estimation of macro- and micronutrient intake and sunlight exposure using structured questionnaires. Serum biochemistry, including 25-hydroxyvitamin D and calcium levels, was measured, and the correlation between variables was determined. Results: 747 participants were enrolled. Significant differences among the three groups were found in mean serum 25-hydroxyvitamin D levels, body mass index, macronutrient intake, dietary vitamin D and calcium content, and sun exposure index (SEI). All except sun exposure (SEI was highest in DS-PTB patients) were found to follow the trend: MDR-TB < DS-PTB < healthy controls. The mean serum vitamin D levels of all groups were deficient and correlated positively with dietary intake and SEI. Conclusion: In this study's we found significant association of serum vitamin D concentrations, dietary intake and sunlight exposure in MDR-TB, DS-PTB patients and healthy controls. Dietary intake may be more important than sun exposure in determining serum levels. However, the significance of this finding is uncertain. Further studies are required to confirm the association, direction, and potential for vitamin D supplementation to treat or prevent MDR-TB infection.

Background: Although previous studies have shown that vitamin A deficiency is associated with incident tuberculosis (TB) disease, the direction of the association has not been established. We investigated the impact of vitamin A deficiency on TB disease progression., Methods: We conducted a longitudinal cohort study nested within a randomized clinical trial among HIV-infected patients in Haiti. We compared serial vitamin A levels in individuals who developed TB disease to controls matched on age, gender, follow-up time, and time to antiretroviral therapy initiation. We also evaluated histopathology, bacterial load, and immune outcomes in TB infection in a guinea pig model of dietary vitamin A deficiency., Results: Among 773 participants, 96 developed incident TB during follow-up, 62.5% (60) of whom had stored serum samples obtained 90-365 days before TB diagnosis. In age- and sex- adjusted and multivariate analyses, respectively, incident TB cases were 3.99 times (95% confidence interval [CI], 2.41 to 6.60) and 3.59 times (95% CI, 2.05 to 6.29) more likely to have been vitamin A deficient than matched controls. Vitamin A-deficient guinea pigs manifested more extensive pulmonary pathology, atypical granuloma morphology, and increased bacterial growth after experimental TB infection. Reintroduction of dietary vitamin A to deficient guinea pigs after established TB disease successfully abrogated severe disease manifestations and altered cellular immune profiles., Conclusions: Human and animal studies support the role of baseline vitamin A deficiency as a determinant of future TB disease progression., Competing Interests: Potential conflicts of interest.

Purpose: The primary aim is to identify the micronutrient deficiencies commonly reported in SSc. The exploratory aim is to evaluate associations between micronutrient deficiencies and SSc clinical manifestations., Patient and Methods: We conducted a scoping review of all published reports on SSc and nutrition in PubMed from its inception to August 2020. Clinical trials, observational studies, meta-analyses, and case series (with ≥20 cases) containing data on nutritional deficiency and SSc were included. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) for reporting our findings. Two reviewers (ADN and ERV) studied the titles and abstracts of all search results with pre-specified inclusion and exclusion criteria., Results: Among 790 retrieved publications, 35 full-length articles and 3 abstracts met the inclusion/exclusion criteria. Included studies took place across multiple geographic locations and included patients with both diffuse and limited cutaneous SSc. Vitamin D deficiency was the most commonly reported deficiency described in SSc, followed by vitamin B12, vitamin B9, selenium, zinc, and iron. In addition, some small studies found deficiencies in vitamins B1, B6, C, E, and A. While some studies reported associations between specific micronutrient deficiencies and SSc disease features (eg, interstitial lung disease was commonly associated with vitamin D deficiency and elevated homocysteine [Hcy]), the evidence to support these associations was not robust., Conclusion: Micronutrient deficiencies are common in SSc and are associated with specific SSc features. Routine screening for micronutrient deficiencies may lead to early detection of malnutrition. Future studies are needed to understand how interventions to replete micronutrient deficiencies affect patient outcomes in SSc., Competing Interests: Elizabeth R Volkmann reports grants and personal fees from Boehringer Ingelheim, and grants from Kadmon, Horizon, Corbus, and Forbius, outside the submitted work.

Nutritional deficiency is prevalent among the elderly, and it is associated with many adverse health consequences. China is rapidly moving toward an aging society with a large population; however, evidence on the epidemiological trends in nutritional deficiency among the Chinese elderly is limited. Data on the incidence of nutritional deficiency among Chinese adults aged 65 years or above from 1990 to 2019 were extracted from the Global Burden of Disease 2019 database. We used the joinpoint regression method to estimate the average annual percentage change (AAPC) and to describe trend patterns. Age, period, and cohort effects were determined using age-period-cohort models. From 1990 to 2019, the incidence of vitamin A deficiency and iodine deficiency among Chinese older adults decreased from 1784.12 and 8.20 to 304.27 and 7.26 per 100,000, with AAPCs of -0.41 (-0.44, -0.38)% and -5.86 (-6.29, -5.43)%, respectively. A continually increasing trend was seen for incidence rates of protein-energy malnutrition, from 1342.02 to 2275.87 per 100,000 person-years, with an AAPC of 1.70 (1.40, 2.01)%. These trends were more pronounced among men than women. A strong age effect and birth cohort effect were present. Specifically, the population that was older or born later had a lower incidence of deficiencies in vitamin A and iodine but a higher incidence of protein-energy malnutrition. The results show a substantial reduction in vitamin A and iodine deficiencies among the Chinese elderly, and health policies and public awareness are needed to address the burden of protein-energy malnutrition in this population.

Background: The intervertebral disc is the largest avascular tissue in the human body. The nucleus pulposus (NP) consumes glucose and oxygen to generate energy to maintain cellular metabolism via nutrients that diffuse from the cartilage endplate. The microenvironment in the intervertebral disc becomes nutritionally deficient during degeneration, and nutritional deficiency has been shown to inhibit the viability and proliferation of NP cells., Methods: To investigate the molecular mechanism by which nutritional deficiency reduces viability and decreases proliferation, we created an in vitro model by using decreasing serum concentration percentages., Results: In this study, we found that nutritional deficiency reduced NP cell viability and increased cell apoptosis and that the upregulation of ATF4 expression and the downregulation of PKM2 expression were involved in this process. Moreover, we found that PKM2 inhibition can reduce the cell apoptosis induced by ATF4 silence under nutritional deficiency., Conclusion: Our findings revealed that PKM2 inhibition reduces the cell apoptosis induced by ATF4 silence under nutritional deficiency by inhibiting AKT phosphate. Revealing the function and mechanism of NP cell development under nutritional deficiency will provide new insights into the etiology, diagnosis, and treatment of intervertebral disc and related diseases., (© 2022.

Objectives: The primary objective of the study was to compare the number of patients with febrile seizure recurrence within 1 year of presenting to our institute, among patients who received and didn't receive oral iron supplementation., Materials and Methods: This prospective intervention study with historical controls was conducted to compare the number of patients with febrile seizure recurrence within 1 year, among patients who received and did not receive oral iron supplementation. The intervention group additionally received prophylactic iron supplementation of 20 mg biweekly for 1 year., Results: A total of 53 patients each were enrolled in both the groups, with comparable baseline characteristics. Although there was a trend toward a lower rate of recurrence of febrile seizures in the interventional group, as compared to the control group, it did not reach the point of statistical significance ( P = 0.35). Both in the worst-case scenario and best-case scenario, there was a trend toward less risk of recurrence of febrile seizure in the intervention group, but it did not reach the point of statistical significance ( P = 0.43 and 0.52). For the original scenario, worst-case scenario, and best-case scenario, the absolute risk reduction was 6.5%, 7%, and 6%, respectively, with corresponding number needed to treat (NNT) being 15, 14, and 16, respectively. The trend for absolute risk reduction was more pronounced in those with complex febrile seizures with an NNT of 6.5, but it still did not reach the point of statistical significance ( P = 0.16). Moderate/severe IDA was also found to be an independent risk factor for recurrence of febrile seizure in the intervention group ( P = 0.03)., Conclusion: Oral serum iron supplementation does not significantly reduce the recurrence rate of febrile seizures in children aged 6-60 months. However, there is a trend toward reduction in the frequency of recurrence of febrile seizures, which is more pronounced in the subset with complex febrile seizures., Competing Interests: There are no conflicts of interest., (© 2022 Published by Scientific Scholar on behalf of Journal of Neurosciences in Rural Practice.)
