Iterative evaluation of mobile computer-assisted digital chest x-ray screening for TB improves efficiency, yield, and outcomes in Nigeria
<p>Wellness on Wheels (WoW) is a model of mobile systematic tuberculosis (TB) screening of high-risk populations combining digital chest radiography with computer-aided automated detection (CAD) and chronic cough screening to identify presumptive TB clients in communities, health facilities, and prisons in Nigeria. The model evolves to address technical, political, and sustainability challenges.</p> <p>Screening methods were iteratively refined to balance TB yield and feasibility across heterogeneous populations. Performance metrics were compared over time. Screening volumes, risk mix, number needed to screen (NNS), number needed to test (NNT), sample loss, TB treatment initiation and outcomes. Efforts to mitigate losses along the diagnostic cascade were tracked. Participants with high likelihood on CAD4TB (≥80) who tested negative on a single spot GeneXpert were followed-up to assess TB status at six months.</p> <p>An experimental calibration method achieved a viable CAD threshold for testing. High-risk groups and key stakeholders were engaged. Operations evolved in real-time to fix problems. Incremental improvements in mean client volumes (128 to 140/day), target group inclusion (92% to 93%), on-site testing (84% to 86%), TB treatment initiation (87% to 91%), and TB treatment success (71% to 85%). Attention to those as highest risk boosted efficiency (the NNT declined from 8.2 ± SD8.2 to 7.6 ± SD7.7). Clinical diagnosis was added after follow-up among those with ≥ 80 CAD scores initially spot-sputum negative found 11 additional TB cases (6.3%) after 121 person-years of follow-up.</p> <p>Iterative adaptation in response to performance metrics foster feasible, acceptable, and efficient TB case-finding in Nigeria. High CAD scores can identify subclinical TB and those at risk of progression to bacteriologically-confirmed TB disease in the near term.</p> <p>Policy makers, donors, and community advocates are hesitant to invest in the steep infrastructure costs for mobile digital chest x-ray and GeneXpert MTB/RIF (dCXR/GXP) laboratories without a better understanding of how to maximize and sustain their impact. It is rarely possible to conduct the months of local CAD calibration recommended by experts via costly universal testing with a reference standard.4,9 Stakeholder needs and resource limitations require a more rapid and cost-conscious means of setting a sustainable algorithm. Viable, field-robust methodologies are needed, and optimization strategies informed by routine field findings were lacking. A precise assessment of the contribution of routine mobile TB screening has been challenging because few authors fully disaggregate losses along the diagnostic cascade or track TB treatment outcomes. Publication bias has limited access to results of active case finding pilots with suboptimal risk group targeting, community engagement, yield, or treatment outcomes.10–14 Evaluations (and scrutiny) of routine data are needed that make the demands, constraints, costs and choices facing implementers more explicit.</p>

Castletown Arra Chest Tomb (TN019-002003-)
Stone lid of a 17th century chest tomb belonging to Terence (Turlogh) O'Brien (1508-1601-) of Castletown Arra and his wife Marie Mor O'Brien (nee O'Carroll) standing up against the external face of the northern wall of Castletown Arra church ruins (TN019-002001-) in County Tipperary. Around the edge of the lid runs a poorly preserved Latin inscription, the lower section of which has been broken off. This family who ruled over the Gaelic territory of Arra lived in the Castle located across the road from the medieval church and graveyard. Terence (Turlogh) O'Brien died February 1601 aged 73 years old. Marie Mor O'Brien (1552-1638) Their son was Murchadh (Murrough, Maurice) O'Brien Aradh, bishop of Killaloe between 1576–1613.

"Ron de Oro" - Treasure Chest Challenge
The great treasure "El Ron de Oro" A rum that can only be obtained from a snake called Cannae Devorantem. Its poison is the most feared, since with its smell it can lead to madness, but every 100 years it undergoes a great transformation into solid gold from the scales to every vein in its body. That day the snake expels its venom, but instead of madness it delivers the Golden Rum, whoever ingests it will enjoy true happiness for the rest of their life. The snake was locked in a barrel after driving an entire town mad, but the temptation of those who captured it by the power of its venom led them to lock it up with enough food to survive for 100 years, hoping to retain its power. It was passed from generation to generation with a ritual that allowed it to be opened every 100 years to collect its poison and deliver food for its awakening. Even today the stories of people who lose their sanity are still heard ... the only thing they remember is a wooden barrel and a whistle inside... Tttsssssssss Source: Objaverse 1.0 / Sketchfab

Stylised Treasure Chest
First attempt at duplicating UVs. A quarter of the model was created and then sculpted and textured. Then the original low poly was mirrored on the X and Z axes. Also my first proper go at using Substance Painter beyond just sticking a smart material on a model and calling it good. Turned out all right but you can see some seams at the lines of symmetry. In the future I will model, then sculpt, then mirror original model, and THEN paint, which will hopefully remove the possibility of those seams. In general though, I am pleased with this model.

HIGH Postimerkkilaatikko - Stamp chest
Postimerkkilaatikkoa on voitu käyttää postimerkkien ja muiden rahanarvoisten paperien säilyttämiseen. Se on ollut käytössä 1890-luvulla. Puusta valmistettu laatikko on vahvistettu raudoituksilla ja sen kansi avautuu saranoilla. Laatikko on ollut alun perin lukittava. Postimerkkilaatikon etusivulla on jäänteitä suurehkosta sinetistä, jolla kansi on voitu sinetöidä esimerkiksi kuljetuksen ajaksi. Stamp chest may have been used for storage of postage stamps and other valuables. It was used from the 1890's onwards. The chest is made of wood and reinforced with iron bands. The chest was furnished with a lock. On the front side of the chest is a large partially preserved wax seal for sealing the lid for transportation or other reasons. The object (PM-ES-87) and 3D model: Finnish Postal Museum (member of Traffic Museums Association). The photogrammetric 3D model may include touch-ups and modelled additions. https://www.finna.fi/Record/postimuseo.1b123a02-eeca-4b19-9158-43e75866922d Source: Objaverse 1.0 / Sketchfab

Low Poly Treasure Chest
A buried treasure is an important part of the popular beliefs surrounding pirates and Old West outlaws. According to popular conception, criminals and others often buried their stolen fortunes in remote places, intending to return for them later, often with the use of treasure maps.

Dendrochonological dataset related to a medieval chest from the city of Antwerp ('Privilegiekom') and several associated wooden boxes, as published by Haneca et al. 2022 in the International Journal of Wood Culture
<p>This repository contains detailed macro-photographs of the wood structure and tree-ring pattern observed on the examined elements of the medieval ‘Privilegiekom’ chest and individual wooden boxes that were stored inside this chest. On these digital macro-photographs the ring-width pattern could be accuratly measured, and are available in this repository as well. The recorded tree-ring series were further analysed and published by <strong>Haneca <em>et al. </em>2022</strong> in the <em><strong>International Journal of Wood Culture</strong></em>.</p>
Pediatric chest lymphoma with segmentation
<p>30 CT scans from 30 different pediatric patients diagnosed with any type of lymphoma were collected. All patients were hospitalized between the years 2013 and 2020. One CT scan per patient was included to maximize potential variance in the data and increase model generalizability. There were 17 boys and 13 girls in the study group, and the mean age was 12.8 (SD 4.1, minimum age 2, maximum age 17).</p> <p>Subsequently, two radiology residents performed segmentation of thoracic lymph nodes in 3D Slicer software. <br> The first 17 segmentations were performed manually. Then, an initial model was trained on these scans and used to perform initial segmentations on the remaining 13 scans to accelerate the process. All initial segmentations were subsequently reviewed by the radiology residents responsible for segmentation, and necessary adjustments were made.</p> <p>Dataset consists of raw CT scans and accompanying segmentation. </p> <p>Dataset publication and collection were funded by Polish National Science Centre grant 2020/36/T/NZ5/00515</p>
