Set of samples resulting from an evaluative, population-based cross-sectional study, approved by the Research Ethics Committee of Federal University of Alfenas, protocol: 415856. These samples pertain to 1,027 rural workers from the southern region of Minas Gerais, Brazil, where comprehensive data on socioeconomic factors, history of pesticide intoxication and hospitalization, and usage of personal protective equipment were collected. Blood samples were obtained to measure biomarkers of pesticide exposure as well as indicators of renal and hepatic sequelae.

This dataset includes data from 43 hospitalized patients with type 2 diabetes mellitus. Dexcom G5 and Dexcom G6 mobile continuous glucose measurement (CGM) devices were used to measure continuous blood glucose levels. The data collection period is from April 2019 to January 2022. We selected 43 patients whose records with a more extended recording period of more than seven days. Data was collected for 7 to 10 days at 5-minute intervals. This data can be used for glucose level prediction or hypoglycemia occurrence prediction for patient with type 2 diabetes mellitus.

The demand for artificial intelligence (AI) in healthcare is rapidly increasing. However, significant challenges arise from data scarcity and privacy concerns, particularly in medical imaging. While existing generative models have achieved success in image synthesis and image-to-image translation tasks, there remains a gap in the generation of 3D semantic medical images. To address this gap, we introduce Med-DDPM, a diffusion model specifically designed for semantic 3D medical image synthesis, effectively tackling data scarcity and privacy issues.

The accurate placement of a needle into the spinal column is critical for spinal anesthesia, spinal taps, and other spinal procedures. Currently, the insertion of the needle is guided by visual and palpation feedback, which can be limited in accuracy and reliability. This study presents a novel approach to providing tactile feedback during needle insertion into the spinal column. This study aims to investigate the effectiveness of providing feedback during the insertion of a needle into the epidural column.

We present a sEMG signal database corresponding to the Indian population named “ElectroMyography Analysis of Human Activities - DataBase -2 (EMAHA-DB2).” This data set consists of two different weight training activities which involve isotonic and isometric contractions. Weight training activities are effective for improving muscle strength, overall health, and regaining limb functionality for people undergoing rehabilitation post stroke-related episodes. The EMG signals acquired during weight training can be used for muscle recruitment analysis.

This article provides an introduction to the field of datasets, including their types, characteristics, and applications. Datasets refer to collections of data that have been organized for specific purposes. They can come in various forms, including structured data, unstructured data, and semi-structured data. Each type of dataset has its own unique characteristics and uses. For example, structured data typically includes datasets that have been organized into tables and rows, such as spreadsheets or databases, while unstructured data typically includes text, images, and videos.

<p> The dataset is digital health data. It contains heart rate data extracted from Fitbit version 2 smartwatch worn by a healthy male Asian person of 48 years old. Data is of one-month duration. We have uploaded a zip file that contains data from different days. Data for each day has a separate file. The file name contains the date. Each file is in csv format. Each file has two columns – timestamp and heart rate. It is a continuous time-series heart rate data. Heart rate was recorded seamlessly at 5 sec interval. However, there may be missing datum.

Objective: The current study investigates
whether, during a Cochlear Implant (CI) surgery, conditioning
(i.e. applying short bursts of electrical stimulation)
within a saline solution can have positive effects on subsequent
intra-operative measurements. We hypothesize that,
based on previous research, the impedance values will be
reduced, and that the reproducibility of Electrically Evoked
Compound Action Potentials (ECAPs) is improved as a
result of conditioning.
Methods: We conditioned half of the electrode contacts,
within a saline solution, before CI insertion, using 23 MEDEL
implants. Impedance was measured for both the conditioned
and non-conditioned groups at five time points.
Repeated ECAP recordings were measured and compared
between the conditioned and non-conditioned groups.
Results: Impedance of the electrode contacts were reduced
by 31% after conditioning in saline solution; however,
there were no clinically relevant differences after
the implantation of the electrode array. The hypothesis
that measurement reproducibility would be increased after
conditioning could not be confirmed with our data.
Within the saline solution, we observed that 44% of the
electrode contacts were covered with air bubbles, which
most disappeared after implantation. However, these air
bubbles limited the effectiveness of the conditioning within
the saline solution. Lastly, the effect of conditioning on the
reference electrode stimulation was approximately 16% of
the total reduction in impedance.
Conclusion: Our data does not suggest that intraoperative
conditioning is clinically required for cochlear implantation
with MED-EL implants. Additionally, an in-vivo ECAP
recording can be considered as a method of conditioning
the electrode contacts.
Significance: We confirm that the common clinical practice
does not need to be changed.

Use of medical devices in the magnetic resonance environment is regulated by standards that include the ASTM-F2213 magnetically induced torque. This standard prescribes five tests. However, none can be directly applied to measure very low torques of slender lightweight devices such as needles. Methods: We present a variant of an ASTM torsional spring method that makes a “spring” of 2 strings that suspend the needle by its ends. The magnetically induced torque on the needle causes it to rotate. The strings tilt and lift the needle.
