Published: September 2023

The delayed sleep phase syndrome (DSPS) is a neurological dream disorder with a multifactorial etiology. It consists of a change between the time of going to sleep and the time of waking up, thus affecting the sleep-wake cycle. This disorder affects people of all ages, nevertheless it has increased in young people due to the use of blue-light emitting electronic devices, such as cell phones, computers, tablets, and others. The use of these short-length waves devices (430- 460 nm; blue light) stimulates the retina’s photoreceptive ganglionic cells inducing the synthesis and secretion of melanop[1]sin. This will inhibit eventually the production and secretion of melatonin, a sleep-inducing hormone produced by the pi[1]neal gland. The prevalence of this syndrome is not well known since it is an underestimated entity. Previous studies show that 16% of the young population worldwide, suffers from this clinical entity. The short and long-term consequences of DSPS are: headaches, somnolence, fatigue, cognitive decline, metabolic and immunologic dysregulation, as well as mental disorders such as anxiety, depression, and bipolarity disorder. Its diagnosis is made following standardized criteria and using subjective tools such as the medical history and a sleep diary. The treatment focuses on pharmacological and non-pharmacological options, such as: melatonin administration, behavioral therapies, and short-length wave blocking devices. The aim of this study was to describe the characteristics of DSPS and emit recommendations to diminish the long-lasting use of blue light-emitting devices.

Los textos dibujan un territorio con pasado glorioso y notables avances, donde comienza a emerger el turismo moderno.
Circulación de imágenes y libros prohibidos en Chiapas. Una aproximación a través del juicio contra un arriero (1844)
Authors: Bárcenas García Felipe
Published: September 2023

Este artículo parte del interés por entender cómo circulaban los libros prohibidos en las regiones periféricas de México y en qué medida la literatura política en boga influyó en los sectores populares durante el siglo XIX. Se analiza el juicio contra un arriero de Tuxtla, Chiapas, en 1844, por poseer una caja de música con una imagen obscena en su interior y una montura con figuras de diablos, así como libros de Rousseau y Voltaire. Esta investigación demuestra que, para reconstruir el circuito del libro decimonónico, no basta con estudiar la trayectoria de los editores y libreros más destacados, sino que también es necesario examinar otro tipo de actores, como los arrieros, quienes, además de comerciar impresos en las zonas más alejadas del centro político y cultural del país, divulgaban oralmente las ideas polémicas de la época en lugares diversos como plazas, caminos, haciendas y comercios.

Authors: Ahmed Idris , Tembhurkar A. R.
Published: September 2023

Abstract: Rapid Urbanization and economic growth of the country has led to increase in vehicular population thereby increasing noise levels. Schools’ buildings especially located at major roadside are often subjected to higher outdoor noise levels wherein the performance of the student is reported to be decreased. Assessment of noise pollution in a school building and providing necessary mitigating measures are deeply felt to prevent deterioration of performance and health. Hence the present study is envisaged to investigate the impact of noise pollution on children in school building located along the roadside. A 12-hours measurements study is recorded in 30 minutes interval using DAWE (Model No. 1421C) sound level meter in Chaitanaya International High School for duration of one month. This study concern with measurement noise levels, its sources, and investigate the effects of noise in the working environment of school building. The study revealed that the LAeq values are between 66 ± 3.7 dBA which are higher compared to permissible values (50 dB (A) during the day and 40 dB (A) at nights) prescribed the Central Pollution Board, New Delhi. On studying the annoyance level, the respondents claimed that the road traffic noise, chatter in the classroom and scraping sounds from tables and chairs are the most annoying noise sources.
Consequences of Psychological Conflict on Handwritings
Authors: Sharma Ravindra , . Deepak , Choudhary Rajat
Published: September 2023

Abstract: Nowadays, stress management has become an important part of our daily life. The inability of an individual to manage stress results in psychological conflict, which ultimately lead to anxious behaviour. This anxious behaviour may cause domestic violence or sometimes results in suicidal attempts. The dying declaration in the form of suicide notes is the crucial evidence in such cases. The admissibility of this crucial evidence in the court of law depends upon the positive identification of the author of suicide notes. It is well established fact that the handwriting of an individual depends upon the neuromuscular coordination, hence handwriting is unique to every individual. Any conflict in brain and condition of muscles of arms and hand, affect the handwriting of an individual. The degree of such effect depends upon the grade of psychological conflict in addition to the condition of muscles of arms and hand. The study presents a exceptional case of suicide in which the Forensic Document Experts (FDEs) infer the effect of psychological conflict on the handwriting executed in the suicide note
Anomaly Detection in Time Series Flight Parameter Data Using Machine Learning Approach
Authors: Shilpi Shama , Aryan Shwetank
Published: September 2023

Abstract: Infrastructure monitoring is more crucial than ever, especially in the aviation industry. To attempt to overcome the difficulties brought on by the problems given by the exponential growth of connected devices and data volume, this study analyzes the application of machine learning approaches for anomaly identification in time series flight parameter data. The introduction of network telemetry, which automates data collecting, is presented as a remedy, however processing enormous data quantities in real-time still poses a challenge. With a focus on time-series data, the paper explores the role of machine learning in network telemetry anomaly detection. Statistical, proximity-based, deviation-based, and supervised classifiers are used to identify anomalies, or departures from predicted patterns, in flight parameter data. For a few examples of anomalous data, long short-term memory networks (LSTMs) are used. The objective is to provide an effective anomaly detection system that can process complex time series flight data and includes data purification, anomaly discovery, temporal reference, and value prediction. The methodology describes the univariate anomaly detection strategy, in which distinct models record particular patterns for each flight parameter. The findings offer new understanding of thresholds, repeated anomaly correction, and prediction errors. The results show that the method is accurate in separating instances of normal data from those containing anomalies, making it a useful tool for practical applications needing accurate anomaly identification.

Published: September 2023

The study looked into i) the relationship that exists between test anxiety and secondary school students’ academic performance in Mathematics. ii) Whether there is difference between the academic performances of students with high and low test anxiety levels in mathematics. Two research questions and two hypotheses guided the study. A correlation survey design was adopted. The study population consisted of 42,299 senior secondary two (SS2) students offering mathematics 2021/2022 in Delta State, Nigeria and 1,650 of those students were selected using a multistage sampling procedure. Mathematics Test Anxiety Questionnaire (MTAQ), which was validated by three experts, was used as the instrument for data collection which had Cronbach Alpha coefficient of 0.69. The students’ achievement scores in Mathematics in SS1 for 2021/2022 session represent their performance scores in the subject. Pearson product moment correlation was used to analyze the collected data. The study’s findings revealed there was a negative correlation and also majority of the students experienced high test anxiety. There was no significant connection between test anxiety and students’ academic performance in mathematics. Also, there was a significant difference between students with high and low anxiety, and their academic performance in mathematics. In light of the findings, it was recommended among other things, that mathematics teachers, school guidance counsellors should make a concerted effort to reduce the test anxiety of their students through proper teaching and conditioning and modeling the behavior of the students for better mathematics performance.

Authors: HARINE G , Bharathi Priya K. , Pavithra A , Jayakumar Devachandran , Farazuddin Mohammed , Tejaswini Satya
Published: September 2023

The aim of the study was to assess DVT prophylaxis using two models (Caprini RAM & DOH tool) for the prevention of DVT in postoperative or critically ill patients and for better predictability of disease. In this prospective observational study, we compared the Caprini RAM and DOH tool in the ICU setting on 229 patients (140 men and 89 women). 205 patients were considered in the study, out of which 97 had Caprini RAM and 108 had DOH tool. A Prospective, observational comparative study was carried out in a tertiary care hospital for a period of 6 months. Patients were divided into two groups according to the RAM. The data were analyzed using SPSS software and the results were compared using the student t-test. Both GROUP A and GROUP B revealed that the majority of the patients (67.1% & 55.6%) were above 60 years and a large proportion of them required DVT prophylaxis. In GROUP A 93% of forms were complete with 79% accuracy. In GROUP B 83% were complete. The most appropriate prophylaxis received by patients was Enoxaparin sodium 40 mg OD for about 97 (30%) patients and Heparin 5000 IU BD for 108 (30%) based on their Caprini scores and NICE guidelines respectively. The majority of patients in Group A did not require dosage adjustments, but in 20% of cases, it was necessary. Statistical significance was achieved with a p-value less than 0.05. The study demonstrates DOH tool is better than Caprini RAM to be used in hospitals, for risk assessment of VTE in both medical and surgical patients for accuracy and predictability of the prophylaxis.

Disintegrants are materials or mixtures of substances added in the drug formulations, which make easier dispersion or breakup of tablets and ingredients of capsules in small-scale particles for fast dissolution then it comes in contact with water in the GI tract. Immediate drug release dosage forms disintegrate rapidly after administration with an enhanced rate of dissolution. The superdisintegrants provide instantaneous disintegration of tablets after administration in the stomach. In this field, immediate-release liquid dosage forms and parenteral dosage forms have also been introduced for treating patients. The oral route is the most convenient route for the administration of solid dosage form, about 85% of solid dosage is administered by the oral route because of its advantages over others. The therapeutic activity of these formulations is obtained through a typical manner like disintegration followed by dissolution. Hence disintegration has a major role in facilitating drug activity. Diverse categories of superdisintegrants such as synthetic, semi-synthetic, natural, co-processed blends, multifunctional superdisintegrants, etc. have been employed to develop effectual orodispersible tablets and to overcome the limitations of conventional tablet dosage forms. The objective of the present review article is to highlight the various kinds of traditional, Natural crude drugs containing gum and mucilage, Co-processed, semisynthetic and synthetic disintegrants along with a concentration in tablet and capsule disintegration and effect on drug release, which are being used in the formulation to provide the safer, effective drug delivery with patient compliance. Also highlights the mechanism and use of disintegrants in the immediate release dosage form.

Crime and Punishment as a Novel of Consciousness
Authors:   State Social and Humanitarian University, Viktorovich Vladimir A.
Published: September 2023

The article proposes a genre definition of Dostoevsky’s novel as a novel of consciousness. The term has been used relatively recently, mainly in English-language literature of the last decades. In this article, it is used in a slightly different sense, emphasizing not the plurality of consciousnesses, but the universalization of consciousness in general. The difference of Crime and Punishment from the tradition of Western European and Russian social and psychological novel was already felt by its first readers and formulated initially by critics N.D. Akhsharumov, N.N. Strakhov, and Fr. Theodore (A.M. Bukharev). The unique fusion of the novel’s hero with the reader was achieved by Dostoevsky on the basis of the postulated common nature of human consciousness. The new aesthetics found its expression in the narrative structure, as the use of improper direct speech builds the communicating vessels (author-hero-reader) of the flowing unified “all-human” consciousness.
The Italian Events of 1867 in Fyodor Dostoevsky’s Calligraphic Sketches: Based on Newspaper Chronicles
Authors:   Institute of Russian Literature (Pushkin House) of the Russian Academy of Sciences, Tarasova Natalia A.
Published: September 2023

The paper examines the calligraphic sketches contained in Dostoevsky’s workbooks with entries for 1867: mentions in calligraphy of the name Garibaldi, as well as Italian toponyms (Acquapendente, Viterbo, Monterotondo, Roma, Tivoli, Frosinone). The analysis of the semantic context formed by these and other calligraphies (inscriptions with the names of Roman Caesars, King of Italy Victor Emmanuel II, Pope Pius IX, etc.) reveals the influence on these records of newspaper periodicals, which widely covered the events of the Risorgimento at that time and attracted the attention of Dostoevsky, as follows from documentary evidence. The context revealed by these calligraphic notes indicates thematic connections between Dostoevsky’s notes of the 1860s, his novels and the future Diary of a Writer.
Semaglutide: A potential treatment of obesity in PCOD patients
Authors: Javeria fnu , Kamal Ayesha , Mohammadi Zohra
Published: September 2023

Semaglutide is a Glucagon Like Peptide GLP agonist, Semaglutide has been
shown to be effective in inducing weight loss in patients with obesity.
Studies have shown that the infusion of GLP 1 results in reduced
gastrointestinal emptying and an increased rate of fasting and
postprandial gastric volumes, resulting in a decrease in hepatic
glycemia. Polycystic ovarian syndrome (PCOS) is the most common
endocrine disorder among women of reproductive age, Semaglutide affects
the brain’s hunger control centers, causing a reduction in food intake
and an increased feeling of fullness, that is helpful in people who are
struggling to lose weight. Multiple trials have shown that introduction
of Semaglutide in regime helps with weight loss in patients of PCOD and
is also effective in management of insulin resistance and lowering high
levels of VLDL, LDL and triglycerides. Possible introduction of
Semaglutide in the treatment of PCOD and obesity should be considered.
Impact of Late Census of India 2021 on Migration: A Review Discussion
Authors: Bordoloi Prantik
Published: September 2023

The Census of India 2021, similar to other national censuses, plays a
crucial role in capturing accurate migration data. However, due to the
unprecedented challenges posed by the COVID-19 pandemic, the census
experienced significant delays, affecting its impact on migration
patterns. This abstract explores the potential consequences of the
delayed census on understanding and analysing migration trends in India.
The nationwide lockdowns and restrictions imposed to curb the spread of
the virus disrupted the regular timeline of conducting the census. The
delayed census raises concerns regarding the accuracy and
comprehensiveness of migration-related data. The pandemic-induced
disruptions in internal and international migration further complicate
the analysis of migration patterns. People’s movement was restricted due
to travel bans, economic uncertainty, and fear of infection.
Consequently, the population shifts and migration trends during the
pandemic might not be adequately captured due to the incomplete census
data. The potential Impact on data sampling techniques used in the
census also warrants attention. The accuracy of population estimates and
statistical inferences related to migration may be affected by limited
access to certain regions or groups of people during the pandemic.
Adjustments and considerations will be essential to account for
potential data biases stemming from these limitations.
Sustainability Metrices for Wind turbine life cycle with environmental impacts, embodied energy and Human toxicity using Open LCA.
Authors: S Shenbagaraman , K Gnanavel B
Published: September 2023

Wind turbines produce electricity with almost no emissions; nonetheless,
there are environmental consequences associated with their life cycle
stages. The present study focus on offshore wind farm in rural areas of
Tamilnadu during their entire life cycle from Manufacturing,
transportation, installation, operation and maintenance, finally
decommissioning with cradle to grave system boundary. The process is
modelled by Open LCA software following ISO 14044 standards. CML, TRACI,
Ecoindicator, and ReCiPe were compared for environmental impacts and
cumulative energy demand for embodies energy assessment respectively.
Acidification, Eutrophication, Global warming, Ozone layer depletion,
and human toxicity were some of the impacts. A Sensitivity analysis was
performed with recycling scenarios for 50% and 80% showed 6 times and
negligible reduction of global warming potential respectively. According
to life cycle analysis, environmental consequences are concentrated in
the manufacturing stage, which accounts for 78% of impacts. Assumptions
in the LCA procedure were methodically addressed, with special emphasis
on the O&M and transportation stages. Steel, iron, epoxy fibers in the
manufacturing stage contributes 84%, 78%, and 86% of total CO2, SOx
and CFC, concrete contributed 85% in the installation stage produces
more emissions and energy intensive. Significant impact category among
all is the human toxicity which contributed by styrene and glass fibres
predominantly affects adults on dermal exposure. The energy pay back
time 1.51 months for the embodied energy calculated was 539 MJeq. Higher
percentage of recycling at the decommissioning stage reduces the kg CO2
emissions by 74 – 83% average.

The global signal (GS) in the brain potentially carries information that
related with neural activities. However, the impacts of the GS on the
interpretation of the consciousness-related measures during different
types of anesthetics-induced unconsciousness remain unknown. Thirteen
glioma patients underwent propofol and sevoflurane induced general
anesthesia were enrolled for analysis. Blood oxygenation level dependent
(BOLD) signals were recorded for all patients in awake state (i.e.,
baseline) and general anesthesia (i.e., unconscious state) by using
functional magnetic resonance imaging (fMRI). Under the scenario of with
GS and without GS, we examined the temporal variability and amplitude of
low-frequency fluctuation (ALFF) to analyze the BLOD changes. The
functional connectivity and brain networks were analyzed to investigate
the alteration in different brain regions. In time domain and frequency
domain analysis, both anesthetics significantly decreased in standard
deviation (SD) (BF10 > 3) under both scenarios. While
comparing baseline to the unconscious state, only propofol exhibited a
significant normalized ALFF reduction under with GS scenario (BF10
> 3). In functional connectivity analysis, removing GS
changed the significance of functional connectivity especially in Limbic
network and Default network for propofol. For sevoflurane, most of
functional connectivity (FC) significances were remarkably altered. In
brain network analysis, removing GS changed the nodal indices, with
different effects on different networks. In summary, for both
anesthetics, the effects of GS had noticeable impacts on in functional
connectivity and brain networks analysis-based measures. GS has a
significant impact on explaining the changes of anesthetics induced
functional connectivity and brain networks.
The influence of coral reef spur and groove morphology on wave energy dissipation and wave overtopping under future climate change scenarios

Published: September 2023

Coral reefs protect coastlines from inundation and flooding, servicing
over 200 million people globally. Wave transformation has previously
been studied on coral reef flats with limited focus on forereef zones
where wave transformation is greatest during high-energy conditions.
This study investigates the role of forereef spur and groove (SaG)
morphology on wave energy dissipation and overtopping on coral reefs.
Using XBeach on LiDAR-derived bathymetry, we reproduced dissipation
rates comparable to SaG field studies. Our results emphasize accurate
bathymetries’ role in forereef wave energy dissipation models by
including morphological features (e.g., groove sinuosity, irregular
forereef slopes) that control the mode of wave energy dissipation
(frictional and breaking). We then investigated changes to wave energy
dissipation and wave overtopping based on IPCC AR5 low and high emission
scenarios (RCP2.6 and RCP8.5) and a total disaster scenario (TD) for the
year 2100 considering changes to SaG morphology, wave power and relative
sea-level rise. For RCP2.6, an increase in wave heights of 0.8 m and an
increase in water level of 0.3 m resulted in a two-fold increase in
dissipation rates. For RCP8.5 and TD, with no increase in incident wave
height, dissipation rates were 29% and 395% lower than RCP2.6. This
resulted in increased overtopping at the reef crest by 1.8 m and 2.7 m
for RCP8.5 and TD scenarios, respectively, when compared to RCP2.6.
Decreased dissipation rates and increased wave overtopping in forecasted
climate conditions suggest the need for strategies to promote coral
growth to facilitate high dissipation rates in the future.
Transient response of Southern Ocean ecosystems during Heinrich stadials
Authors: Saini Himadri , Meissner Katrin Juliane , Kvale Karin F , Menviel Laurie
Published: September 2023

Antarctic ice core records suggest that atmospheric CO2 increased by 15
to 20 ppm during Heinrich stadials (HS). These periods of abrupt CO2
increase are associated with a significant weakening of the Atlantic
meridional overturning circulation (AMOC), and a warming at high
southern latitudes. As such, modelling studies have explored the link
between changes in AMOC, high southern latitude climate and atmospheric
CO2. While proxy records suggest that the aeolian iron input to the
Southern Ocean decreased significantly during HS, the potential impact
on CO2 of reduced iron input combined with oceanic circulation changes
has not been studied in detail. Here, we quantify the respective and
combined impacts of reduced iron fertilisation and AMOC weakening on CO2
by performing numerical experiments with an Earth system model under
boundary conditions representing 40,000 years before present (ka). Our
study indicates that reduced iron input can contribute up to 6 ppm rise
in CO2 during an idealized Heinrich stadial. This is caused by a 5%
reduction in nutrient utilisation in the Southern Ocean, leading to
reduced export production and increased carbon outgassing from the
Southern Ocean. An AMOC weakening under 40ka conditions and without
changes in surface winds leads to a ~0.5 ppm CO2
increase. The combined impact of AMOC shutdown and weakened iron
fertilisation is almost linear, leading to a total CO2 increase of 7
ppm. Therefore, this study highlights the need of including changes in
aeolian iron input when studying the processes leading to changes in
atmospheric CO2 concentration during HS.

The thyroid gland is affected by many factors, such as age, gender, and ethnicity. The gland is also influenced by metabolism, stress, and psychological state. In this clinical scenario, establishing a reference period for TSH, T3, and T4 is critical for the diagnosis of thyroid functional disorders before and after screening. The aim of this study is to assess the effect of mental stress on the levels of TSH, T3, and T4 before and after the exam. The study was conducted from December until the end of February 2022 at the Middle Technical College, University of Baghdad. 45 healthy young students, ranging in age from 19 to 23 years, were included in this study. The results found a significant difference between T4 levels in pre- and post-exam in males when compared with females, and there was also a difference between the levels of T3 and TSH in pre- and post-exam. Conclusion: Mental stress affects thyroid hormones by affecting the central regulation of TSH levels.
Increased Incidence in Gestational Diabetes Mellitus by Race and Ethnicity during the COVID-19 Pandemic: Results from a Large Medical Center in the United States
Authors: Chen Liwei
Published: September 2023

Background: Gestational diabetes mellitus (GDM) is a common pregnancy complication, and its risk increases in females exposed to stressful events. The COVID-19 pandemic has affected the healthcare system and individuals’ behaviors, but its impact on GDM risk remains unclear. We aimed to investigate the influence of the pandemic on GDM risk in the United States (US), overall and by race/ethnicity. Methods: This retrospective cohort study included pregnancies in an academic medical system in Los Angeles, California. We divided 8,518 pregnancies into the pre-COVID cohort (4,507 delivered between 9/1/2018 and 2/29/2020; 18 months) and the intra-COVID cohort (4,011 delivered between 3/1/2020 and 8/31/2021; 18 months). We ascertained GDM cases using the ICD-10 codes, calculated the age-standardized GDM incidences, and estimated the risk ratios (RR) of GDM (intra-COVID vs. pre-COVID) using Poisson regressions. Results: The age-standardized GDM incidence was 8.49% in the pre-COVID and 10.02% in the intra-COVID cohorts. The GDM risk was 17% higher in the intra-COVID cohort than in the pre-COVID cohort (RR=1.17; 95% CI: 1.02, 1.35) after adjusting for race/ethnicity, maternal age, nulliparity, marital status, pre-pregnancy body mass index, gestational weight gain, and utilization days of prenatal care. When stratified by race/ethnicity, the GDM risk was higher in non-Hispanic Whites (RR=1.34; 95% CI: 1.03, 1.74), Hispanics (RR=1.26; 95% CI: 1.00, 1.59), and potentially in non-Hispanic Blacks (RR=1.32; 95% CI: 0.63, 2.76), but not in Asians (RR=0.99; 95% CI: 0.75, 1.30). Conclusion: GDM incidences increased during the COVID-19 pandemic in a large US city, especially among non-Hispanic Whites, Hispanics, and non-Hispanic Blacks.
Persistence of Measles Transmission despite of Measles Elimination Program Progressing
Authors: Yoshikura Hiroshi
Published: September 2023

The number of measles cases per million was plotted in linear scale or in logarithmic scale in the vertical axis along years from 1974 to 2021 in the horizontal axis. In the linear scale plot, measles cases persisted with consecutive peaks till early 1990s and then became invisible. In logarithmic scale plot, the plots were horizontally distributed at high level till early 1990s and declined to lower level with ups and downs. Though proportion of measles cases in older population gradually increased over time, as of 2021, the number of measles cases was still correlated with population size of age group <14 years.
Current COVID-19 Epidemic Risks in Brazil
Authors: Liu Zirui
Published: September 2023

This research uses raw clinical observational data to propose a new spatio-temporal approach for the precise prediction of the likelihood of the COVID-19 epidemic occurring at any moment in any interest Brazil state. This article presents a new bio-system reliability method that is especially appropriate for multi-regional environmental and health systems and that has been watched for a long enough time to produce a reliable long-term forecast of the likelihood of a virus outbreak. All impacted Brazilian states' daily COVID-19 recorded patient counts were taken into consideration. This research sought to benchmark a cutting-edge technique that allows for the analysis of dynamically witnessed patient numbers while accounting for pertinent regional mapping. The suggested strategy might assist in keeping track of and forecasting potential pandemic breakouts in a wide range of multi-regional biological systems.

Published: September 2023

Introduction & BackgroundThe shift towards plant-based diets remains on the rise. Several observational studies have suggested that adopting these diets can result in some fundamental nutrient deficiencies, such as iodine deficiency. This can be especially harmful to a developing fetus, leading to growth impairment and, in extreme cases, cretinism. Nonetheless, understanding of long-term health consequences of this shift remains a challenge, particularly regarding nutritional impact at broader population scales.

Objectives & ApproachOur study focuses on the effects of transitioning to plant-based diets on the purchasing and assumed intake of essential nutrients like iodine, calcium, and vitamin B12. We analysed anonymized shopping records of 10,626 loyal customers who switched from regular milk to alternative milk products. By matching the transaction data with nutritional information, we estimated the weekly nutrient purchases before and after the transition. Our data was collected from a national food retailer across the UK.

Relevance to Digital FootprintsLoyalty-card transactional logs held by retailers reflect a valuable lens into nutritional intake data. This data can provide insight into the potential impact of purchasing behaviours, such as the potential health effects of dietary changes at scale. Our approach leverages AI modelling accompanied by rigorous variable importance methods to uncover potentially hidden insights on the impact of nutritional shifts to plant-based goods.

ResultsResults indicate that 83% of individuals deemed regular customers, who switched to plant-based milk, experienced a decrease in their purchases of iodine (44%), calcium (30%), and vitamin B12 (39%) from their normal purchase patterns at the retailer. Additionally, 57% of these individuals decreased their iodine purchases by more than 50%. The reduction in these nutrients is even more significant for those who switch to plant-based dairy and meat products.

Conclusions & ImplicationsOur research indicates that dietary changes, such as switching from purchasing regular milk to alternative milks, may lead to insufficient intake of essential dietary nutrients such as iodine. This represents a significant potential health concern for the public if not remediated, especially in countries that do not require salt to be fortified with iodine.
