Palpreast—A New Wearable Device for Breast Self-Examination

Portable noninvasive technologies for early breast cancer detection: A systematic review

Breast cancer remains a leading cause of cancer mortality worldwide, with early detection crucial for improving outcomes. This systematic review evaluates recent advances in portable non-invasive technologies for early breast cancer detection, assessing their methods, performance, and potential for clinical implementation. A comprehensive literature search was conducted across major databases for relevant studies published between 2015 and 2024. Data on technology types, detection methods, and diagnostic performance were extracted and synthesized from 41 included studies. The review examined microwave imaging, electrical impedance tomography (EIT), thermography, bioimpedance spectroscopy (BIS), and pressure sensing technologies. Microwave imaging and EIT showed the most promise, with some studies reporting sensitivities and specificities over 90 %. However, most technologies are still in early stages of development with limited large-scale clinical validation. These innovations could complement existing gold standards, potentially improving screening rates and outcomes, especially in underserved populations, whiles decreasing screening waiting times in developed countries. Further research is therefore needed to validate their clinical efficacy, address implementation challenges, and assess their impact on patient outcomes before widespread adoption can be recommended.

Bioinspired Materials for Wearable Devices and Point-of-Care Testing of Cancer

Wearable, point-of-care diagnostics, and biosensors are on the verge of bringing transformative changes in detection, management, and treatment of cancer. Bioinspired materials with new forms and functions have frequently been used, in both translational and commercial spaces, to fabricate such diagnostic platforms. Engineered from organic or inorganic molecules, bioinspired systems are naturally equipped with biorecognition and stimuli-sensitive properties. Mechanisms of action of bioinspired materials are deeply connected with thermodynamically or kinetically controlled self-assembly at the molecular and supramolecular levels. Thus, integration of bioinspired materials into wearable devices, either as triggers or sensors, brings about unique device properties usable for detection, capture, or rapid readout for an analyte of interest. In this review, we present the basic principles and mechanisms of action of diagnostic devices engineered from bioinspired materials, describe current advances, and discuss future trends of the field, particularly in the context of cancer.

Breast Cancer Awareness and Associated Factors Amongst Women in Peshawar, Pakistan: A Cross-Sectional Study

BACKGROUND

Breast cancer is the most common cancer in women, and the second overall, following lung cancer. Breast cancer can occur at any age, with an increased incidence in women 40 years and above. Worldwide the incidence is around 1 million cases per year, 60% of the cases reported from low- and middle-income countries. The current study was conducted to determine knowledge, attitude, and practices related to breast cancer, the associated risk factors, and screening methods in women presenting to a health care facility from resource-poor settings in Pakistan.

METHODS

A cross-sectional study design was used, and participants were recruited phase-wise from three major outpatient departments (OPDs) (Gynecology and Obstetrics OPD, Medical OPD, and Surgical OPD). Data were collected through the validated "Breast Cancer Awareness Measure" developed by Cancer Research UK, King's College London, and University College London in 2009. Data were analyzed through Statistical Package for Social Sciences software (SPSS) version 23.0. Students's T-Test, ANOVA, and linear regression analysis were conducted.

RESULTS

A total of 430 women were invited for participation in the study from the 3 main OPDs, and 400 took part in the study (response rate = 93.02%). The mean age of the women was 33.62 years ± 12.3 years, and the mean years of formal education were 5.05 ± 6.3 years. Less than a quarter of the participants were aware of the breast cancer warning signs, and 23.3% recognized the pain in the armpit or one of the breasts as a sign of breast cancer. The proportion of women aware of age-related and lifetime risk of getting breast cancer was 15.0%. Furthermore, only 2.5% performed breast self-examination at least once a month. Women identified many barriers like embarrassment, transport, and confidentiality issues in seeking medical help.

CONCLUSION

Overall, women had poor knowledge of breast cancer, related warning signs, breast self-examination, risk factors, and screening methods.

Co-design open-source medical devices: how to minimize the human error using UBORA e-infrastructure

In the complex context of the medical device industry and healthcare systems, the reduction in cost may increase access to medical technologies moving towards global health equity. This paper is focused on the description of UBORA, an e-infrastructure based on a new concept of biomedical engineering which promotes the open-source approach for co-designing medical devices, fostering innovative ideas, needs-based, low-cost and safe technology. UBORA structures the entire design process using EN ISO 13485:2016, standard related to medical technology for inspiration. As a proof of concept, this paper shows an example of the development of an open source medical device for hand rehabilitation, designed using UBORA. We demonstrate the straightforward pathway to gather information on safety requirements. Finally, we describe a usability test of the e-infrastructure performed during the 4^th WHO Global Forum on Medical Devices in India.
