The impact of area-level socioeconomic status in childhood on mental health in adolescence and adulthood: A prospective birth cohort study in Aotearoa New Zealand.

Mental health conditions pose a significant public health challenge, and low area-level socioeconomic status (SES) is a potentially important upstream determinant. Childhood exposure might have influences on later-life mental health. This study, utilises data from the Christchurch Health and Development Study birth cohort, examining the impact of area-level SES trajectories in childhood (from birth to age 16) on mental health at age 16 and from age 18-40 years. Findings revealed some associations between distinct SES trajectories and mental health. The study underscores the importance of using a spatial lifecourse epidemiology framework to understand long-term environmental impacts on later-life health.

Genome sequencing reanalysis increases the diagnostic yield in dystonia.

PURPOSE: We investigated the contribution of genomic data reanalysis to the diagnostic yield of dystonia patients who remained undiagnosed after prior genome sequencing. METHODS: Probands with heterogeneous dystonia phenotypes who underwent initial genome sequencing (GS) analysis in 2019 were included in the reanalysis, which was performed through gene-specific discovery collaborations and systematic genomic data reanalysis. RESULTS: Initial GS analysis in 2019 (n = 111) identified a molecular diagnosis in 11.7 % (13/111) of cases. Reanalysis between 2020 and 2023 increased the diagnostic yield by 7.2 % (8/111); 3.6 % (4/111) through focused gene-specific clinical correlation collaborative efforts [VPS16 (two probands), AOPEP and POLG], and 3.6 % (4/111) by systematic reanalysis completed in 2023 [NUS1 (two probands) and DDX3X variants, and a microdeletion encompassing VPS16]. Seven of these patients had a high phenotype-based dystonia score ≥3. Notable unverified findings in four additional cases included suspicious variants of uncertain significance in FBXL4 and EIF2AK2, and potential phenotypic expansion associated with SLC2A1 and TREX1 variants. CONCLUSION: GS data reanalysis increased the diagnostic yield from 11.7 % to 18.9 %, with potential extension up to 22.5 %. While optimal timing for diagnostic reanalysis remains to be determined, this study demonstrates that periodic re-interrogation of dystonia GS datasets can provide additional genetic diagnoses, which may have significant implications for patients and their families.

Variation in harms and benefits of prostate-specific antigen screening for prostate cancer by socio-clinical risk factors: A rapid review.

Objective: To analyse the latest evidence on the relative harms and benefits of screening and diagnostic pathways with close examination of (i) men aged 50 years or older, (ii) men whose ethnicity places them at higher risk and (iii) men with a family history. Methods: We conducted a literature search using PubMed and Cochrane Central Register of Controlled Trials (CENTRAL) databases and other sources, from January 1990 to 25 January 2023. Two independent reviewers selected for randomised controlled trials (RCTs) and cohort studies which met our inclusion criteria. Results: Twenty-eight articles were selected, from six trials, including the Göteborg trial-reported separately from European Randomised Study of Screening for Prostate Cancer (ERSPC). Prostate-specific antigen (PSA)-based screening led to the increased detection of low-grade cancer and reduction of advanced/metastatic disease but had contradictory effects on prostate cancer (PCa)-specific mortality (no difference or reduced), possibly due to issues of contamination or compliance. Screening men from a relatively young age (50-55) reduced risk of PCa-specific mortality in a subanalysis of an 18-year follow-up study and in a 17-year cohort study from the main Göteborg trial. Moreover, one Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial analysis reported a trend of reduced risk of PCa-specific mortality for men with a family history who were screened. [Correction added on 05 March 2024, after first online publication: "Cancer Screening Trial" has been added to the preceding sentence.] However, we did not find relevant studies for ethnicity. Conclusion: Under current UK practice, the choice to conduct a PSA test relies on a shared decision-making approach guided by known risk factors. However, we found there was a lack of strong evidence on the harms and benefits of PSA screening by socio-clinical risk factors and suggest further research is required to understand the long-term impact of screening on high-risk populations in the current diagnostic setting.

The impact of pre-biopsy MRI and additional testing on prostate cancer screening outcomes: A rapid review.

Objective: This work aims to examine the latest evidence on the impact of pre-biopsy MRI, in addition to prostate-specific antigen (PSA) testing, on health outcomes and quality of life. Methods: We conducted a literature search including PubMed and Cochrane Central Register of Controlled Trials (CENTRAL) databases, with a limited scan of (i) guidelines and (ii) references from trial reports, from January 2005 to 25th January 2023. Two independent reviewers selected randomised controlled trials (RCT) and cohort studies which met our inclusion criteria. Results: One hundred thirty-seven articles were identified, and seven trial articles were selected. Trial interventions were as follows: (i) PSA blood test, (ii) additional tests such as pre-biopsy multiparametric magnetic resonance imaging (mpMRI) and Biparametric MRI (bpMRI), and (iii) MRI targeted biopsy and standard biopsy. Compared with standard biopsy, MRI-based interventions led to increased detection of clinically significant cancers in three studies and decreased detection of clinically insignificant cancer (Gleason grade 3 + 3) in four studies. However, PROstate Magnetic resonance Imaging Study (PROMIS) and Stockholm3 with MRI (STHLM3-MRI) studies reported different trends depending on the scenario studied in PROMIS (MRI triage and MRI directed biopsy vs. MRI triage and standard biopsy) and thresholds used in STHLM3-MRI (≥0·11 and ≥0·15). MRI also helped 8%-49% of men avoid biopsy, in six out of seven studies, but not in STHLM3-MRI at ≥0.11. Interestingly, the proportion of men who experienced sepsis and UTI was low across studies. Conclusion: This review found that a combination of approaches, centred on the use of pre-biopsy MRI, may improve the detection of clinically significant cancers and reduce (i) the diagnosis of clinically insignificant cancers and (ii) unnecessary biopsies, compared with PSA testing and standard biopsy alone. However, the impact of such interventions on longer term outcomes such as prostate cancer-specific mortality has not yet been assessed.

Proximity of alcohol outlets and presentation to hospital by young people after self-harm: A retrospective geospatial study using the integrated data infrastructure.

OBJECTIVES: There is a well-established association between alcohol use, misuse, intoxication and self-harm, the latter of which is associated with suicide. This study aimed to better understand the association between proximity to alcohol outlets and the likelihood of young people presenting to hospital following self-harm. METHODS: This was a nationwide retrospective geospatial study using data from the New Zealand Integrated Data Infrastructure using population-level data for 10-29-year-olds for the 2018 and 2017 calendar years. Presentations to hospital following self-harm were identified using the national minimum data set. Proximity to alcohol outlets was defined in road network distance (in kilometres) and ascertained using Integrated Data Infrastructure geospatial data. Alternative measures of proximity were employed in sensitivity analyses. Complete-case two-level random intercept logistic regression models were used to estimate the relationship between alcohol outlet proximity and hospital presentation for self-harm. Adjusted models included sex, age, ethnicity, area-level deprivation, urbanicity and distance to nearest medical facility. Analyses were also stratified by urbanicity. RESULTS: Of the 1,285,368 individuals (mean [standard deviation] age 20.0 [5.9] years), 7944 (0.6%) were admitted to hospital for self-harm. Overall, the odds of presenting to hospital for self-harm significantly decreased as the distance from the nearest alcohol outlet increased, including in adjusted models (adjusted odds ratio 0.980; 95% confidence interval = [0.969-0.992]); the association was robust to changes in the measure of alcohol proximity. The effect direction was consistent across all categorisations of urbanicity, but only statistically significant in large urban areas and rural areas. CONCLUSIONS: The findings of this study show a clear association between young people's access to alcohol outlets and presentation to hospital for self-harm and may provide a mandate for government policies and universal interventions to reduce young people's access to alcohol outlets. Further research regarding causative mechanisms is needed.

Association between air temperature and unintentional drowning risk in the United Kingdom 2012-2019: A nationwide case-crossover study.

OBJECTIVE: Drowning is a leading cause of death. The World Health Organization (WHO) and United Nations (UN) emphasise the need for population-level data-driven approaches to examine risk factors to improve water safety policies. Weather conditions, have the potential to influence drowning risk behaviours as people are more likely to spend time around water and/or undertake risky activities in aquatic spaces as a behavioural thermoregulatory response (e.g., seeking coolth). METHODS: A case-crossover approach assessed associations between changes in daily maximum air temperature (data from the nearest weather station to each drowning event) and unintentional drowning risk using anonymous data from the validated UK Water Incident Database 2012-2019 (1945 unintentional deaths, 82% male). Control days were selected using a unidirectional time-stratified approach, whereby seven and 14 days before the hazard day were used as the controls. RESULTS: Mean maximum air temperature on case and control days was 15.36 °C and 14.80 °C, respectively. A 1 °C increase in air temperature was associated with a 7.2% increase in unintentional drowning risk. This relationship existed for males only. Drowning risk was elevated on days where air temperature reached 15-19.9 °C (Odds Ratio; OR: 1.75), 20-24.9 °C (OR: 1.87), and ≥ 25 °C (OR: 4.67), compared with days <10 °C. The greatest elevations in risk appeared to be amongst males and when alcohol intoxication was suspected. Precipitation showed no significant association with unintentional drowning risk. CONCLUSIONS: Identifying such relationships highlights the value of considering weather conditions when evaluating environmental risk factors for drowning, and may inform water safety policy and allocating resources to prevention and rescue.

InAsSb Photodiode Fibre Optic Thermometry for High-Speed, near-Ambient Temperature Measurements.

Infrared radiation thermometers (IRTs) overcome many of the limitations of thermocouples, particularly responsiveness and calibration drift. The main challenge with radiation thermometry is the fast and reliable measurement of temperatures close to room temperature. A new IRT which is sensitive to wavelengths between 3 µm and 11 µm was developed and tested in a laboratory setting. It is based on an uncooled indium arsenide antimony (InAsSb) photodiode, a transimpedance amplifier, and a silver halogenide fibre optic cable transmissive in the mid- to long-wave infrared region. The prototype IRT was capable of measuring temperatures between 35 °C and 100 °C at an integration time of 5 ms and a temperature range between 40 °C and 100 °C at an integration time of 1 ms, with a root mean square (RMS) noise level of less than 0.5 °C. The thermometer was calibrated against Planck's law using a five-point calibration, leading to a measurement uncertainty within ±1.5 °C over the aforementioned temperature range. The thermometer was tested against a thermocouple during drilling operations of polyether ether ketone (PEEK) plastic to measure the temperature of the drill bit during the material removal process. Future versions of the thermometer are intended to be used as a thermocouple replacement in high-speed, near-ambient temperature measurement applications, such as electric motor condition monitoring; battery protection; and machining of polymers and composite materials, such as carbon-fibre-reinforced plastic (CFRP).

Change in the food environment and measured adiposity in adulthood in the Christchurch Health and development birth cohort, Aotearoa, New Zealand: A birth cohort study.

This study investigated associations between change in the food environment and change in measured body mass index (BMI) and waist circumference (WC) in the Christchurch Health and Development Study (CHDS) birth cohort. Our findings suggest that cohort members who experienced the greatest proportional change towards better access to fast food outlets had the slightly larger increases in BMI and WC. Contrastingly, cohort members who experienced the greatest proportional change towards shorter distance and better access to supermarkets had slightly smaller increases in BMI and WC. Our findings may help explain the changes in BMI and WC at a population level.

A new national health system: the opportunity to address data quality issues in maternal immunisation coverage.

AIM: Maternal immunisation coverage is suboptimal in Aotearoa New Zealand. Our objective was to highlight discrepancies resulting from how maternal immunisation coverage for pertussis and influenza is measured in Aotearoa New Zealand. METHOD: A retrospective cohort study of pregnant people was undertaken using administrative datasets. Maternity and immunisation data from three sources (National Immunisation Register [NIR], general practice [GP], and pharmaceutical claims) were linked to determine the proportion of immunisation records not recorded in the NIR but captured in claims data, and to compare this with coverage data available from Te Whatu Ora - Health New Zealand. RESULTS: We found that while increasing numbers of maternal immunisations are being captured in the NIR, around 10% remain unrecorded on the NIR, but within claims datasets. CONCLUSION: Accurate maternal immunisation coverage data is important for public health action. Implementation of the whole-of-life Aotearoa Immunisation Register (AIR) is an important opportunity to improve completeness and consistency of maternal immunisation coverage reporting.

Adolescents and oral health service utilization in Canterbury, New Zealand: A geospatial cross-sectional study.

OBJECTIVE: Non-utilization of dental care during adolescence can result in poorer oral health and subsequently higher expenditures on dental services. This study examined the geospatial and epidemiological factors associated with utilization of the publicly funded Adolescent Oral Health Services (AOHS) in Canterbury, Aotearoa New Zealand (NZ). METHODS: A secondary analysis of prospectively collected routine data from AOHS visits of adolescents in school Year 9 (13-14 years) for the financial year 2019-2020. Geographic information systems examined distance from home to dental practices. Multilevel mixed-effects Poisson regression models investigated associations between geospatial, demographic and clinical factors and non-utilization of dental services. Models were adjusted for sex, ethnicity, area-level deprivation, rural/urban classification, previous caries experience and the distance from home address to dental practice referred. RESULTS: Dental practices were concentrated in large urban areas and in the least deprived neighbourhoods, with several service area gaps identified. Rural areas and the most deprived areas of Christchurch City had the highest non-utilization rates. After adjustment, adolescents residing in the most deprived areas had a higher risk of non-utilization (adjusted risk ratio [aRR] = 1.38; 95% CI 1.26-1.51) compared to adolescents in the least deprived areas. Adolescents in remote areas also had an increased risk of non-utilization (aRR = 1.36; 95% CI 1.20-1.54) compared to adolescents in urban core areas. Finally, Maori (aRR = 1.37; 95% CI 1.29-1.46) and Pasifika (aRR = 1.46; 95% CI 1.35-1.59) adolescents had significantly higher risks of non-utilization compared to their NZ European counterparts. CONCLUSION: Inequitable utilization of dental services exists among adolescents in Canterbury, NZ, and is associated with Maori, Pasifika and those living in rural and most deprived areas. Adolescents at the greatest oral health risk are geographically underserved by current oral health services. The current health system should also explore the possibility of partnering with Maori and Pasifika communities to provide services within culturally appropriate settings.

Disparities in utilisation of combined oral contraceptives in Aotearoa New Zealand: A cross-sectional whole-of-population study.

AIMS: The combined oral contraceptive (COC) is the most commonly used hormonal contraceptive in Aotearoa New Zealand (Aotearoa/NZ). Currently there is limited data available on who uses COC in Aotearoa/NZ. The aims were to (i) define the population of reproductive-aged females in Aotearoa/NZ in 2018 and identify the rate of COC use among this group and (ii) describe the sociodemographic and geographic characteristics of the population of COC users compared to the general population of reproductive-aged females in 2018. METHODS: This whole-of-population cross-sectional study used the Integrated Data Infrastructure, a large research database managed by Statistics New Zealand. Females aged 16-50 years with complete sociodemographic and geographic information in 2018 from Aotearoa/NZ's estimated resident population were included. COC dispensing records to this cohort were identified from the national Pharmaceutical Collection. This paper reports descriptive counts of COC use and employs generalised linear regression with a binomial distribution and a log link to estimate adjusted risk ratios (aRR) of COC use for key sociodemographic and geographic subgroups. RESULTS: Of 1 113 750 individuals in the study, 159 789 (14.3%) were dispensed as COC in 2018. European/other individuals were most likely to use COC (aRR: 2.72, 2.67-2.78), and Pacific Peoples were least likely (aRR: 0.56, 0.55-0.58) to use COC. Individuals residing in the most deprived quintile had less COC use than individuals in the least deprived quintile (aRR: 0.73, 0.72-0.74). CONCLUSION: Our study is able to highlight significant disparities in use by ethnicity, area-level deprivation, and geographic factors.

Economic evaluation of population-based, expanded reproductive carrier screening for genetic diseases in Australia.

PURPOSE: This study aimed to evaluate the cost effectiveness of population-based, expanded reproductive carrier screening (RCS) for a 300 recessive gene panel from health service and societal perspectives. METHODS: A microsimulation model (PreConMod) was developed using 2016 Australian Census data as the base population. Epidemiologic, health, and indirect cost data were based on literature review. The study assessed the incremental cost effectiveness ratio of expanded RCS compared with (1) no population screening and (2) 3-condition screening for cystic fibrosis, spinal muscular atrophy, and fragile X syndrome in a single birth cohort. Averted affected births and health service savings with expanded RCS were projected to year 2061. Both one-way and probability sensitivity analyses were conducted to assess the uncertainty of the parameter inputs. RESULTS: Expanded RCS was cost saving compared with no population screening and cost effective compared with the 3-condition screening (incremental cost effectiveness ratio of Australian dollar [AUD] 6287 per quality-adjusted life year gained) at an uptake rate of 50% for RCS, 59% for in vitro fertilization and preimplantation genetic testing, 90% for prenatal diagnosis testing, and 50% for elective termination of affected pregnancies and a cost of AUD595 per couple screened. Our model predicts that expanded RCS would avert one-third of affected births in a single birth cohort and reduce lifetime health service spending by AUD632.0 million. Expanded RCS was estimated to be cost saving from the societal perspective. CONCLUSION: Expanded RCS is cost effective from health service and societal perspectives. Expanded RCS is projected to avert significantly more affected births and result in health service saving beyond those expected from 3-condition screening or no population screening.

Improving longitudinal research in geospatial health: An agenda.

All aspects of public health research require longitudinal analyses to fully capture the dynamics of outcomes and risk factors such as ageing, human mobility, non-communicable diseases (NCDs), climate change, and endemic, emerging, and re-emerging infectious diseases. Studies in geospatial health are often limited to spatial and temporal cross sections. This generates uncertainty in the exposures and behavior of study populations. We discuss a research agenda, including key challenges and opportunities of working with longitudinal geospatial health data. Examples include accounting for residential and human mobility, recruiting new birth cohorts, geoimputation, international and interdisciplinary collaborations, spatial lifecourse studies, and qualitative and mixed-methods approaches.

The pattern of association between early childhood caries and body mass index in pre-school children within Aotearoa | New Zealand: a national cross-sectional study.

OBJECTIVES: The relationship between childhood anthropometric measurements and dental caries has an inconsistent evidence-base. This study investigated dental caries experience and body mass index (BMI) measurements of children aged 4 years in a national cohort, after accounting for key confounding variables. METHODS: A near whole-population cross-sectional study of children who had a health and developmental assessment, as part of the nationwide B4 School Check screening program, conducted in Aotearoa | New Zealand (ANZ) between 1 July 2010 and 30 June 2021 was studied. The extracted database included 582 820 children, of whom 572 523 (98.2%) had valid BMI and oral health records. Dental caries experience was derived from the 'lift the lip' oral health screening, and measured height and weight were used to calculate sex-specific BMI-for-age z-scores (BMIz). Analyses were adjusted for age, sex, ethnicity and area-level deprivation. Modified Poisson regression models using 2-degree fractional polynomial curves for BMIz were employed. RESULTS: In the extracted sample, the median age was 4.3 years (interquartile range: 4.1-4.5 years), 283 565 (48.7%) were female, 135 734 (23.4%) and 74 237 (12.8%) were identified as Maori and Pacific, respectively, and 140 931 (24.4%) lived in the most deprived areas of ANZ. Overall, 81 926 (14.2%) had dental caries identified. In unadjusted analyses, a significant J-shaped association was observed between dental caries experience and BMIz. However, in the adjusted analysis, a significant flattened S-shaped association was found; those with lower BMIz had lower predicted probabilities of dental caries experience. Large differences in predicted probabilities were observed between different sex, ethnicity and area-level deprivation groups. CONCLUSIONS: This study found significant non-linear associations between dental caries experience and BMI in 4-year-old children. However, the inclusion of confounders importantly changed the shape of this non-linear association. Sex, ethnicity and area-level deprivation inequalities had a greater impact on dental caries experience than BMI.

Investigating where adolescents engage in moderate to vigorous physical activity and sedentary behaviour: An exploratory study.

BACKGROUND: There is a persistent lack of understanding on the influence of the environment on behaviour and health. While the environment is considered an important modifiable determinant of health behaviour, past research assessing environments often relies on static, researcher-defined buffers of arbitrary distance. This likely leads to misrepresentation of true environmental exposures. This exploratory study aims to compare researcher-defined and self-drawn buffers in reflecting the spaces and time adolescents engage in physical activity (PA) and sedentary behaviour. It also investigates if adolescent's access the PA facility and greenspace nearest their home or school for PA, as well as examine how much time adolescents spent in PA at any PA facilities and greenspaces. METHODS: Adolescents (aged 14-18 years; n = 34) were recruited from schools in West Yorkshire, England. Seven consecutive days of global positioning system (GPS) and accelerometer data were collected at 15 second intervals. Using ArcGIS, we compared 30 different researcher-defined buffers including: radial, network and ellipse buffers at 400m, 800m, 1000m, 1600m and 3000m and participant-defined self-drawn neighbourhoods to objectively measured PA and sedentary space and PA time. Location of PA was also compared to Points of Interest data to determine if adolescents use the nearest PA facility or greenspace to their home or school and to examine how much PA was undertaken within these locations. RESULTS: Our exploratory findings show the inadequacy of researcher-defined buffer size in assessing MVPA space or sedentary space. Furthermore, less than 35% of adolescents used the greenspaces or PA facilities nearest to their home or school. Approximately 50% of time spent in PA did not occur within the home, school, PA facility, or greenspace environments. CONCLUSION: Our exploratory findings help to begin to quantify the inadequacy of researcher-defined, and self-drawn buffers in capturing adolescent MVPA and sedentary space, as well as time spent in PA. Adolescents often do not use PA facilities and greenspaces nearest their home and school and a large proportion of PA is achieved outside PA facilities and greenspaces. Further research with larger samples are needed to confirm the findings of this exploratory study.

Aerosol jet printing polymer dispersed liquid crystals on highly curved optical surfaces and edges.

We demonstrate a new technique for producing Polymer Dispersed Liquid Crystal (PDLC) devices utilising aerosol jet printing (AJP). PDLCs require two substrates to act as scaffold for the Indium Tin Oxide electrodes, which restricts the device geometries. Our approach precludes the requirement for the second substrate by printing the electrode directly onto the surface of the PDLC, which is also printed. The process has the potential to be precursory to the implementation of non-contact printing techniques for a variety of liquid crystal-based devices on non-planar substrates. We report the demonstration of direct deposition of PDLC films onto non-planar optical surfaces, including a functional device printed over the 90° edge of a prism. Scanning Electron Microscopy is used to inspect surface features of the polymer electrodes and the liquid crystal domains in the host polymer. The minimum relaxation time of the PDLC was measured at 1.3 ms with an 800 Hz, 90 V, peak-to-peak (Vpp) applied AC field. Cross-polarised transmission is reduced by up to a factor of 3.9. A transparent/scattering contrast ratio of 1.4 is reported between 0 and 140 V at 100 Hz.

High-Speed Infrared Radiation Thermometer for the Investigation of Early Stage Explosive Development and Fireball Expansion.

The understanding of blast loads is critical for the development of infrastructure that protects against explosions. However, the lack of high-quality experimental work on the characterisation of such loads prevents a better understanding of many scenarios. Blast loads are typically characterised by use of some form of pressure gauge, from which the temperature can be inferred from a pressure measurement. However, such an approach to temperature measurement is limited; it assumes ideal gas laws apply throughout, which may not be the case for high temperature and pressure scenarios. In contrast, infrared radiation thermometers (IRTs) perform a measurement of temperature based upon the emitted radiance from the target object. The IRTs can measure fast changes in transient temperature, making them seemingly ideal for the measurement of a fireball's temperature. In this work, we present the use of a high-speed IRT for the measurement of early-stage explosive development and fireball expansion within a confined blast, with the temperature of the explosive fireball measured from its emitted radiance. The temperature measured by the IRT was corroborated against the temperature inferred from a pressure gauge measurement; both instruments measured the same temperature from the quasi-static pressure (QSP) point onwards. Before the QSP point, it is deduced that the IRT measures the average temperature of the fireball over a wide field-of-view (FOV), as opposed to that inferred from the singular shocks detected by the pressure gauge. Therefore, use of an IRT, in tandem with a pressure gauge, provides a potential invaluable measurement technique for the characterisation the early stages of a fireball as it develops and expands.

High-Resolution Hyperspectral Imaging Using Low-Cost Components: Application within Environmental Monitoring Scenarios.

High-resolution hyperspectral imaging is becoming indispensable, enabling the precise detection of spectral variations across complex, spatially intricate targets. However, despite these significant benefits, currently available high-resolution set-ups are typically prohibitively expensive, significantly limiting their user base and accessibility. These limitations can have wider implications, limiting data collection opportunities, and therefore our knowledge, across a wide range of environments. In this article we introduce a low-cost alternative to the currently available instrumentation. This instrument provides hyperspectral datasets capable of resolving spectral variations in mm-scale targets, that cannot typically be resolved with many existing low-cost hyperspectral imaging alternatives. Instrument metrology is provided, and its efficacy is demonstrated within a mineralogy-based environmental monitoring application highlighting it as a valuable addition to the field of low-cost hyperspectral imaging.
