Jain S, Lamba BY, Dubey SK. Recent advancements in the sensors for food analysis to detect gluten: A mini-review [2019-2023]. Food Chem 2024; 449:139204. [PMID: 38613992 DOI: 10.1016/j.foodchem.2024.139204] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 03/24/2024] [Accepted: 03/29/2024] [Indexed: 04/15/2024]
Abstract
People with celiac disease or gluten sensitivity may experience an immune reaction to the protein called gluten, which is present in wheat, barley, and rye. A strict gluten-free diet is the sole cure for these ailments. There are chances of food fraud about the claim of being gluten-free food items. As a result, there is a rising need for trustworthy and precise ways to identify gluten. There are many methods to detect gluten in food samples viz., enzyme-linked immunosorbent assay 1 Surface plasmon resonance (SPR), Electrochemical sensors, Fluorescence-based sensors, etc. The use of sensors is one of the most promising methods for gluten detection. For detecting gluten, a variety of sensors, including optical, electrochemical, and biosensors, have been developed with different limits of detection and sensitivity. The present review reports the recent advancements (2019-2023) in the development of sensors for gluten detection in food. We may conclude that sensitivity and limit of detection are not related to the type of sensor used (aptamer or antibody-based), however, there are advancements, with the year, on the simplicity of the material used like paper-based sensors and paradigm shift to reagent free sensors by the spectral analysis. Also, recent work shows the potential of IoT-based studies for gluten detection.

Abstract
Ionic liquids (ILs) are a class of liquid salts with characteristics such as a low melting point, an ionic nature, non-volatility, and tunable properties. Because of their adaptability, they have a significant influence in the field of fluorescence. This paper reviews the primary literature on the use of ILs in fluorescence sensing technologies. The kind of target material is utilized to classify the fluorescence sensors made with the use of ILs. They include using ILs as probes for metals, nitro explosives, small organic compounds, anions, and gases. The efficacy of an IL-based fluorescence sensor depends on the precise design to guarantee specificity, sensitivity, and a consistent reaction to the desired analyte. The precise method can differ depending on the chemical properties of the IL, the choice of fluorophore, and the interactions with the analyte. Overall, the viability of the aforementioned materials for chemical analysis is evaluated, and prospective possibilities for further development are identified.

Evaluation of 700 patients referred with a preliminary diagnosis of biotinidase deficiency by the national newborn metabolic screening program: a single-center experience. J Pediatr Endocrinol Metab 2023:jpem-2023-0003. [PMID: 37119528 DOI: 10.1515/jpem-2023-0003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 04/08/2023] [Indexed: 05/01/2023]
Abstract
OBJECTIVES This study aimed to investigate the clinical, demographic and laboratory characteristics of the patients referred with a preliminary diagnosis of biotinidase deficiency through the national newborn metabolic screening program. We also attempted to determine the cut-off level of the fluorometric method used for screening biotinidase deficiency by the Ministry of Health. METHODS A total of 700 subjects who were referred to the Pediatric Metabolism Outpatient Clinic with a preliminary diagnosis of biotinidase deficiency through the national newborn metabolic screening program were retrospectively evaluated. Patients detected by family screening were excluded. Biotinidase enzyme activity was assessed and BTD gene analysis was performed in all patients. RESULTS Of 700 subjects who were referred by the screening program, 284 (40.5 %) had biotinidase deficiency (BD). The enzyme activity was 0-10, 10-30 and >30 % in 39 (5.5 %), 245 (35 %) and 416 (59.5 %) patients, respectively. The BD was partial in majority of patients (86.2 %). The cut-off level was 59.5 MRU for partial BD and 50.5 MRU for profound BD. The most common mutation detected was p.Arg157His (c.470G>A) among patients with profound BD, and p.D444H (c.1330G>C) among patients with partial BD. CONCLUSIONS Treatment should be initiated promptly in patients who are referred by the newborn screening program. Any mean activity under 59.5 MRU should be considered partial BD, while less than 50.5 MRU should be considered profound BD. It should be kept in mind that clinical manifestations may develop both in profound and partial BD.

Abstract
Innovative medical education greatly relies on lifelong learning with universal standards in research, for generating novel knowledge for improvement maximum patient care. The other side of innovative medical education relies on success of development of novel ideas, perspective; skill building, future career objectives. Leaders have curious roles in the research assistant education. In the current century, both technology and education raced forward in many countries. Mobbing and bullying is an important problem in all fields, every sphere of life in workplaces. Unethical behavior must not take place in universities because universities are the centers of learning, and best academic teaching in ethical standards. Bullying may damage every individual in every academic degree and effect academic performance. In this paper I will discuss a mobbing case which is done to a young academician in many years ago, which is not most frequently observed type. However, such bullying behaviors may increase due to COVID-19 pandemic. Because COVID-19 pandemic may cause various problems in social groups difficulties, anxiety, and economic challenges, problems. Nowadays everybody is experiencing worry, uncertainty, anxiety, fear of economic problems, fear of dying. COVID-19 pandemic has created some unexpected problems to everybody however, academic researchers have additional worries and fears such as; the expiration time of chemicals, problems on chemicals are not imported from abroad on time also difficulties of knockout or transgenic experimental animals cannot be imported from abroad on time, and all these problems cause fear of unsuccessful experimental results, spending extra time. All these anxieties may cause arouse increasing unstable friendships and mobbing possibilities. The COVID-19 disease takes our future and experimental plans to waste basket and change everything including friendship.

High Incidence of Partial Biotinidase Deficiency in the First 3 Years of a Regional Newborn Screening Program in Italy. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19138141. [PMID: 35805799 PMCID: PMC9265859 DOI: 10.3390/ijerph19138141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Revised: 06/28/2022] [Accepted: 06/29/2022] [Indexed: 02/04/2023]
Abstract
Biotinidase deficiency (BD) is an autosomal recessive inherited disorder in which the enzyme biotinidase is totally or partially defective and the vitamin biotin is not recycled. BD meets the major criteria for a population screening program. Newborn bloodspot screening (NBS) allows early diagnosis of BD, thus preventing the high morbidity and mortality associated with untreated disease. Both profound and partial BD variant can be detected by NBS test, and serum enzyme activity and/or mutational analysis are required for definitive diagnosis. In Italy, BD is included in the screening panel for inborn errors of metabolism (IEMs) that has been declared mandatory in 2016. We analyzed the data of the first 3 years of the NBS for BD in our region (Abruzzo, Italy), with the aim to describe the outcomes of this recently introduced screening program. In over 26,393 newborns screened, we found 2 carriers and 16 cases with genotype associated with partial BD. Since the serum biotinidase assay has been recently introduced in our algorithm, only three of our newborns met the criteria of genetic and biochemical confirmation, with an incidence of 1:8797, which is in the high range of what has been reported in the literature. All affected infants carried the 1330G>C (D444H) variant in compound heterozygosis, with variants known to be associated with profound BD. A variant previously not described and likely pathogenic was found in one newborn. None of the infants had signs or symptoms. The study of the distribution of the enzyme activity in our population allowed us to validate the adopted cutoff with which the program has a positive predictive value of 18% and to analyze some preanalytical factors influencing biotinidase activity: A correlation of the enzyme activity with gestational age and time at specimen collection was found. Lower mean values of enzyme activity were found in infants born in the summer.

Abstract
Background Biotinidase deficiency (OMIM 253260) is an autosomal recessively inherited disorder affecting about 1/60,000 people worldwide. The absence or deficiency of biotinidase impairs free biotin recycling and affects biotin‐dependent carboxylase functions. Methods A Chinese patient with spontaneous recurrent epilepsy, an eczema‐like rash, hair loss, hypotonia, and hearing loss began at three months of age. Her biotinidase activity was 1.0 nmol/ml/min, 9.5% of the mean control activity, which confirmed profound biotinidase deficiency. Results Compound heterozygous for c.250‐1G > C and c.878dupT variants in the BTD gene were identified in this patient. These two variants were novel and absent in the population matched controls and any databases. Conclusions This study expanded the mutation spectrum of alterations of the BTD gene. Our patient also emphasized the critical role of biotinidase activity measurement combined with mutation analysis in early diagnosis of biotinidase deficiency.

Abstract
Disclaimer: These ACMG Standards and Guidelines are intended as an educational resource for clinical laboratory geneticists to help them provide quality clinical laboratory genetic services. Adherence to these Standards and Guidelines is voluntary and does not necessarily assure a successful medical outcome. These Standards and Guidelines should not be considered inclusive of all proper procedures and tests or exclusive of others that are reasonably directed to obtaining the same results. In determining the propriety of any specific procedure or test, clinical laboratory geneticists should apply their professional judgment to the specific circumstances presented by the patient or specimen. Clinical laboratory scientists and geneticists are encouraged to document in the patient's record the rationale for the use of a particular procedure or test, whether or not it is in conformance with these Standards and Guidelines. They also are advised to take notice of the date any particular guideline was adopted, and to consider other relevant medical and scientific information that becomes available after that date. It also would be prudent to consider whether intellectual property interests may restrict the performance of certain tests and other procedures.Biotinidase deficiency is an autosomal recessively inherited disorder of biotin recycling that is associated with neurologic and cutaneous consequences if untreated. Fortunately, the clinical features of the disorder can be ameliorated or prevented by administering pharmacological doses of the vitamin biotin. Newborn screening and confirmatory diagnosis of biotinidase deficiency encompasses both enzymatic and molecular testing approaches. These guidelines were developed to define and standardize laboratory procedures for enzymatic biotinidase testing, to delineate situations for which follow-up molecular testing is warranted, and to characterize variables that can influence test performance and interpretation of results.

Abstract
Background Alzheimer’s disease (AD) is a severe multifactorial neurodegenerative proteopathy associated with advanced age. Discrepancies in the renal function of these patients compared to geriatric patients with dementia have rarely been reported. In this study, we aimed to disclose the importance of associated renal changes for the pathogenesis of AD. Methods Patients with AD (n=107) and geriatric patients with dementia and without dementia (n=124) (231 patients in total) from Dokuz Eylul and Cukurova University Hospitals were enrolled in the study. We measured serum Na, K, Cl, Ca, BUN, creatinine, total protein levels and MDRD [eGFR] in all groups. Results From Izmir Center, the first study arm consisted of patients with AD dementia (n=74), and the second arm included geriatric patients with dementia (n=79). From Adana, 78 patients were recruited to the study, of which 33 were with AD and 45 were geriatric patients without dementia. When we analyzed comparatively the AD and geriatric dementia patients study arms, a statistically significant difference was observed both in the median age (p<0.001), as well as in the biochemical parameters from Izmir Center: Na (p<0.001), K (p<0.001), Cl (p<0.05), Ca (p<0.001), BUN (p<0.05), creatinine (p<0.001), total protein (p<0.001) and MDRD [eGFR] (p<0.001). However, these were not significantly different between AD and geriatric patients without dementia in the Adana group. Conclusions Our results indicate that renal function is prone to alterations in different age groups of patients with AD. However, there is no conclusive evidence that renal function is one of the risk factors in AD.
