Toward a tipping point in federated learning in healthcare and life sciences.

We discuss the real-world application of federated learning (FL) in the healthcare and life sciences industry, noting a tipping point in its adoption beyond academia. Sharing our experiences with multi-hospital and multi-pharma collaborations, we highlight the importance of involving key stakeholders to develop production-grade FL solutions that are fully compliant with stringent privacy and security standards.

A photometric stereo-based 3D imaging system using computer vision and deep learning for tracking plant growth.

Background: Tracking and predicting the growth performance of plants in different environments is critical for predicting the impact of global climate change. Automated approaches for image capture and analysis have allowed for substantial increases in the throughput of quantitative growth trait measurements compared with manual assessments. Recent work has focused on adopting computer vision and machine learning approaches to improve the accuracy of automated plant phenotyping.

Innovative 3D and 2D machine vision methods for analysis of plants and crops in the field.

Machine vision systems offer great potential for automating crop control, harvesting, fruit picking, and a range of other agricultural tasks. However, most of the reported research on machine vision in agriculture involves a 2D approach, where the utility of the resulting data is often limited by effects such as parallax, perspective, occlusion and changes in background light - particularly when operating in the field. The 3D approach to plant and crop analysis described in this paper offers potential to obviate many of these difficulties by utilising the richer information that 3D data can generate.

Does Graves' disease or thyrotoxicosis affect the prognosis of thyroid cancer.

Twenty-one patients who underwent surgical treatment for thyrotoxicosis and who were found at operation to have thyroid cancer are presented. Sixteen had Graves' disease and 5 had toxic nodular goiter. The group with Graves' is compared with 110 euthyroid patients with thyroid cancer who underwent their initial surgery in the same time period and who were of the same age (+/- 1 yr) and sex as the patients with Graves' disease.

A therapeutic dilemma: suppressive doses of thyroxine significantly reduce bone mineral measurements in both premenopausal and postmenopausal women with thyroid carcinoma.

We measured lumbar spine, femoral neck, and forearm bone mineral (BMD) in 24 women (14 premenopausal and 10 postmenopausal) who had been treated with total thyroidectomy and 131 Iodine ablation therapy for nonanaplastic thyroid carcinoma and 24 case controls. At the time of the study, all patients were free of cancer (negative 131 Iodine whole body scan and serum thyroglobulin levels less than 0.3 micrograms/L) and all were receiving doses of T4 sufficiently high to prevent a rise in a serum thyroid-stimulating hormone concentration after an iv bolus of TRH.

The effect of o,p'-DDD on adrenal steroid replacement therapy requirements.

Two patients with adrenal carcinoma treated with 2,2-bis (2-chlorophenyl-4-chlorophenyl)-1,1-dichloroethane (o,p'-DDD) as adjuvant therapy were studied. Both patients developed hypoadrenalism while on o,p'-DDD and apparently adequate dexamethasone replacement therapy. The hypoadrenalism was overcome by increasing steroid replacement therapy.

The assay for thyroid stimulating immunoglobulins using cultured human thyroid cells.

Recent reports have shown that thyroid-stimulating immunoglobulins (TSI) may be detected by measuring cyclic AMP increases in cultures of isolated thyroid cells in response to added patient immunoglobulins (Ig). We have compared the frequency that TSI may be detected in the Ig fraction of 114 sera from 112 patients with a variety of thyroid disorders, to the presence of thyrotrophin binding inhibitor Ig (TBII). Whereas the sera of 46 out of 48 (95.

Cardiac function in acute hypothyroidism.

It has been established that chronic hypothyroidism may affect cardiac function by several mechanisms. It is not known how long the patient has to be hypothyroid for cardiac involvement to develop. This study was undertaken to assess the effect of a short period of hypothyroidism (10 days) on cardiac function.

Two cases of lymphoma of the parotid gland following ablative radioiodine therapy for thyroid carcinoma.

Two adult patients are described in whom 131I therapy thyroid carcinoma was followed by the development of non-Hodgkin's lymphoma in salivary glands. Histologically one was lymphocytic and the other histiocytic. The total doses of 131I given were 27 GBq (675 mCi) and 14GBq (350 mCi), lymphoma presenting 10 and 3 years respectively after the initial therapeutic dose of 131I.

A comparative study of 99mTc and 131I in thyroid scanning.

Thyroid scans performed with both 99mTc pertechnetate (99mTcO4) and (131I) were compared in 46 patients with palpable thyroid nodules to determine whether 131I scanning is any longer a necessary procedure. A discrepancy between the two types of scan existed in only three cases, in one of which the thyroid nodule showed uptake of 99mTcO4 but not of 131I. Subsequent surgery revealed a thyroid malignancy in this patient.

Thyroid stimulating immunoglobulin in Graves' disease.

There is excellent presumptive evidence that an IgG plays an aetiological role in the development of hyperthyroidism in Graves' disease but available methods for detecting thyroid stimulating immunoglobulins (TSI) are still far from satisfactory. They show considerable variation in specificity, sensitivity and precision, and comparison of the experimental data, obtained with these various methods, is difficult. A need exists for an in vitro TSI assay which is based upon the propensity of IgG molecules to stimulate the thyroid gland.

Small cell carcinoma of the lung: primary site and hepatic metastases both detected on Tc-99m-pyrophosphate bone scan.

A case of small cell anaplastic carcinoma of the lung with hepatic secondaries has been found to accumulate Tc-99m-pyrophosphate in both lung primary and hepatic metastases and to our knowledge is the first such case reported in the literature. There was no radiographic evidence of calcification in the tumor or hepatic metastases.

Transient metastatic calcification in primary hyperparathyroidism.

Metastatic calcification has been visualised on bone scan in many hypercalcaemic states. This report illustrates the phenomenon occurring in a patient with primary hyperparathyroidism and its subsequent disappearance after therapy.

High ectopic kidney presenting as an abnormal liver-lung scan: case report.

An unusual cause for a positive liver-lung scan is presented. A cold area between the base of the right lung and the liver in a 78-year-old woman was reported as being due to a subphrenic abscess. This defect was subsequently found to be a right subphrenic kidney.
