Objective: Early detection and treatment of cervical precancers can prevent disease progression. However, in low-resource communities with a high incidence of cervical cancer, high equipment costs and a shortage of specialists hinder preventative strategies. This manuscript presents a low-cost multiscale in vivo optical imaging system coupled with a computer-aided diagnostic system that could enable accurate, real-time diagnosis of high-grade cervical precancers., Methods: The system combines portable colposcopy and high-resolution endomicroscopy (HRME) to acquire spatially registered widefield and microscopy videos. A multiscale imaging fusion network (MSFN) was developed to identify cervical intraepithelial neoplasia grade 2 or more severe (CIN 2+). The MSFN automatically identifies and segments the ectocervix and lesions from colposcopy images, extracts nuclear morphology features from HRME videos, and integrates the colposcopy and HRME information., Results: With a threshold value set to achieve sensitivity equal to clinical impression (0.98 [p = 1.0]), the MSFN achieved a significantly higher specificity than clinical impression (0.75 vs. 0.43, p = 0.000006)., Conclusion: Our findings show that multiscale optical imaging of the cervix allows the highly sensitive and specific detection of high-grade precancers., Significance: The multiscale imaging system and MSFN could facilitate the accurate, real-time diagnosis of cervical precancers in low-resource settings.

Background: The World Psychiatric Association recently emphasised that the protection of human rights in mental healthcare was a 'central concern'. This paper examines recent literature on human rights and mental healthcare., Aims: To (a) outline how international human rights law distinguishes between the protection and promotion of human rights; and (b) explore the literature on promoting human rights in mental healthcare which avoids what has been termed the 'Geneva impasse' between those who argue that compulsory care and treatment can never comply with human rights law and those who argue that they can if certain conditions are met., Method: The following doctrinal methodology was used: (a) identification and detailed analysis of international human rights conventions and commentaries; (b) identification of key literature on human rights and mental healthcare; and (c) critical analysis of key issues emerging from the literature., Results: Much of the literature on human rights and mental healthcare focuses on whether restrictions on compulsory care are required to meet the requirements of United Nations Conventions. There is an emerging literature identifying measures to promote the right to the enjoyment of the highest attainable standard of mental health., Conclusions: There has been a focus on protecting the rights to liberty and equality before the law for mental health patients. The nascent literature on promoting human rights in mental healthcare could mark a way forward beyond the 'Geneva impasse' that has dominated public debate in recent years.

Significance: Despite recent advances in multimodal optical imaging, oral imaging systems often do not provide real-time actionable guidance to the clinician who is making biopsy and treatment decisions., Aim: We demonstrate a low-cost, portable active biopsy guidance system (ABGS) that uses multimodal optical imaging with deep learning to directly project cancer risk and biopsy guidance maps onto oral mucosa in real time., Approach: Cancer risk maps are generated based on widefield autofluorescence images and projected onto the at-risk tissue using a digital light projector. Microendoscopy images are obtained from at-risk areas, and multimodal image data are used to calculate a biopsy guidance map, which is projected onto tissue., Results: Representative patient examples highlight clinically actionable visualizations provided in real time during an imaging procedure. Results show multimodal imaging with cancer risk and biopsy guidance map projection offers a versatile, quantitative, and precise tool to guide biopsy site selection and improve early detection of oral cancers., Conclusions: The ABGS provides direct visible guidance to identify early lesions and locate appropriate sites to biopsy within those lesions. This represents an opportunity to translate multimodal imaging into real-time clinically actionable visualizations to help improve patient outcomes., (© 2023 The Authors.)

Cervical cancer remains a leading cause of cancer death among women in low-and middle-income countries. Globally, cervical cancer prevention programs are hampered by a lack of resources, infrastructure, and personnel. We describe a multimodal mobile colposcope (MMC) designed to diagnose precancerous cervical lesions at the point-of-care without the need for biopsy. The MMC integrates two complementary imaging systems: 1) a commercially available colposcope and 2) a high speed, high-resolution, fiber-optic microendoscope (HRME). Combining these two image modalities allows, for the first time, the ability to locate suspicious cervical lesions using widefield imaging and then to obtain co-registered high-resolution images across an entire lesion. The MMC overcomes limitations of high-resolution imaging alone; widefield imaging can be used to guide the placement of the high-resolution imaging probe at clinically suspicious regions and co-registered, mosaicked high-resolution images effectively increase the field of view of high-resolution imaging. Representative data collected from patients referred for colposcopy at Barretos Cancer Hospital in Brazil, including 22,800 high resolution images and 9,900 colposcope images, illustrate the ability of the MMC to identify abnormal cervical regions, image suspicious areas with subcellular resolution, and distinguish between high-grade and low-grade dysplasia., Competing Interests: R.

Traditional methods to detect and quantify nucleic acids rely on polymerase chain reaction (PCR) and require the use of expensive thermocyclers with integrated fluorescence detection of amplicons. Isothermal nucleic acid amplification technologies eliminate the need for thermal cycling; however, fluorescence-based detection of products is still required for real-time, quantitative results. Several portable isothermal heaters with integrated fluorescence detection are now commercially available; however, the cost of these devices remains a significant barrier to widespread adoption in resource-limited settings. Described here is a protocol for the design and assembly of a modular, low-cost fluorimeter constructed from off-the-shelf components. Enclosed in a compact 3D printed housing, the fluorimeter is designed to be placed atop a commercially available heat block holding a PCR tube. The fluorimeter described here was optimized to detect fluorescein isothiocyanate (FITC) dye, but the system can be modified for use with dyes commonly used as reporters in real-time nucleic acid amplification reactions. Clinical applicability of the system is demonstrated by performing real-time nucleic acid detection with two isothermal amplification technologies: recombinase polymerase amplification (RPA) for detection of positive control DNA provided in a commercial kit and reverse transcription loop-mediated isothermal amplification (RT-LAMP) for detection of clinically meaningful levels of SARS-CoV-2 RNA.

The use of physical, mechanical and/or chemical restraint is authorised by mental health legislation in most Australian jurisdictions. Research indicates that women have different experiences and needs in relation to the use of restraint, but legislation does not mention sex or gender as relevant considerations in the authorisation, use or monitoring of these practices. This is especially problematic in light of the potential for restraint use to traumatise, or retraumatise, women service users. This section discusses the treatment of gender- and trauma-related considerations in Australian mental health legislation and supporting policy, pointing to several gaps and proposing appropriate changes to practice and regulation., Competing Interests: None.

The World Health Organization and several United Nations bodies and personnel have called for a human rights perspective to be integrated into mental health and community services. While there are ongoing debates about what this means for law reform and practice, the World Health Organization QualityRights program provides a starting point for educational training in human rights that may be of benefit for mental health practitioners. This column explores some of the challenges for integrating a human rights perspective into mental health treatment and care and outlines the QualityRights program.
