Deep Personalized Medical Recommendations Based on the Integration of Rating Features and Review Sentiment Analysis

To comply with the rapid development of big data in mobile services, an increasing number of websites have begun to provide users with recommendation decisions in various areas, like shopping, tourism, food, and medical treatment. However, there are still some challenges in the field of medical recommendation systems, such as the lack of personalized medical recommendations and the problem of data sparseness, which seriously restricts the effectiveness of such recommendations. In this paper, we propose a personalized medical recommendation method based on a convolutional neural network that integrates revised ratings and review text, called revised rating and review based on a convolutional neural network (RR&R-CNN). First, the review text is divided into user and doctor datasets, and BERT vectorized representations are performed on them. Moreover, the original rating features are revised by adding the sentiment analysis values of the review text. Then, the vectorized review text and the revised rating features are spliced together and input into the convolutional neural network to extract the deep nonlinear feature vectors of both users and doctors. Finally, we use a factorization machine for feature interaction. We conduct comparison experiments based on a Yelp dataset in the “Health & Medical” category. The experimental results confirm the conclusion that RR&R-CNN has a better effect compared to a traditional method.

Sexism in Russian neurosurgery

The work is devoted to the study of the issue of gender inequality in Russian neurosurgery. Materials and methods: the study is based on an anonymous survey of neurosurgeons working in Russia. The authors have developed 2 questionnaires, different for men and women. 103 certified neurosurgeons were interviewed, 53 of them were men and 50 — women. Results: on average, male neurosurgeons were older, with more work experience, more often had a medical category (p <0.05) and performed a greater number of independent operations (p <0.01). In all the same questions characterizing the perception of the image of a female neurosurgeon, significant differences were revealed between men and women (p <0.01). Women do not feel less trust in the quality of their work because of their gender, but throughout their medical education and work, they regularly face the notion that neurosurgery is not a suitable profession for women. Harassment is not a typical phenomenon in Russian neurosurgery. Among the authors of articles in the 5 most cited Russian neurosurgical journals for 2016–2018, there were 20.7 % women; 15 % of the first authors were women. Conclusions: female neurosurgeons in Russia face manifestations of gender discrimination in the professional environment, which is an additional obstacle to becoming a neurosurgeon. The perception of the image of a female neurosurgeon differs significantly among neurosurgeons, depending on their gender.

Assessing the Quality of Mobile Health-Related Apps: Interrater Reliability Study of Two Guides

Background There is a huge number of health-related apps available, and the numbers are growing fast. However, many of them have been developed without any kind of quality control. In an attempt to contribute to the development of high-quality apps and enable existing apps to be assessed, several guides have been developed. Objective The main aim of this study was to study the interrater reliability of a new guide — the Mobile App Development and Assessment Guide (MAG) — and compare it with one of the most used guides in the field, the Mobile App Rating Scale (MARS). Moreover, we also focused on whether the interrater reliability of the measures is consistent across multiple types of apps and stakeholders. Methods In order to study the interrater reliability of the MAG and MARS, we evaluated the 4 most downloaded health apps for chronic health conditions in the medical category of IOS and Android devices (ie, App Store and Google Play). A group of 8 reviewers, representative of individuals that would be most knowledgeable and interested in the use and development of health-related apps and including different types of stakeholders such as clinical researchers, engineers, health care professionals, and end users as potential patients, independently evaluated the quality of the apps using the MAG and MARS. We calculated the Krippendorff alpha for every category in the 2 guides, for each type of reviewer and every app, separately and combined, to study the interrater reliability. Results Only a few categories of the MAG and MARS demonstrated a high interrater reliability. Although the MAG was found to be superior, there was considerable variation in the scores between the different types of reviewers. The categories with the highest interrater reliability in MAG were “Security” (α=0.78) and “Privacy” (α=0.73). In addition, 2 other categories, “Usability” and “Safety,” were very close to compliance (health care professionals: α=0.62 and 0.61, respectively). The total interrater reliability of the MAG (ie, for all categories) was 0.45, whereas the total interrater reliability of the MARS was 0.29. Conclusions This study shows that some categories of MAG have significant interrater reliability. Importantly, the data show that the MAG scores are better than the ones provided by the MARS, which is the most commonly used guide in the area. However, there is great variability in the responses, which seems to be associated with subjective interpretation by the reviewers.

In situ grommet and fitness for flying

Introduction: Current policies followed in the country do not permit aircrew to fly with in situ grommet. This paper discusses the aeromedical implications of in situ grommet, assessment of its flying fitness, and the factors which may be considered for possible reflighting of such cases. Case Details: A 19 year old civil pilot developed otitic barotrauma middle ear (right) which was managed with the placement of grommet in the tympanic membrane (TM). He was awarded fitness to fly on removal of grommet and after complete closure of the residual TM perforation. Another case, a 50 year old military pilot, a case of chronic suppurative otitis media (inactive) left ear, after uneventful recovery, was awarded flying medical category initially for in situ grommet and subsequently for single dry perforation TM in the left ear with an waiver from the competent medical authority. Discussion: Insertion of grommet, in cases with middle ear effusion and/or infection following Eustachian tube dysfunction, is a common practice to promote early recovery. However, as per the current policies in India, such aircrew are considered unfit for flying duty. Policies in other countries, military and civil, are mostly silent. This paper recommends the award of flying fitness for aircrew with in situ grommet provided that the clinical condition is stable, there are no complications and hearing is normal. This paper also discusses the award of flying fitness for aircrew with single and uncomplicated TM perforation with normal hearing for a specific type of aircraft.

Is there a pathological way of ageing?

This think piece discusses ‘Alzheimer’s disease’ from a critical anthropological perspective. I aim to challenge the taken-for-granted biomedical framing in four steps. First, a brief genealogical account shows that Alzheimer’s disease as a biomedical category has only recently become a public and global health preoccupation. Second, the concept of medicalization is mobilized to illustrate the construction of and the uncertainty around this new medical object. Third, I build a case for analysing this medical category within a sociocultural context. Finally, a brief account of the relevance of social intervention is given.

Aphrodisiacs in the global history of medical thought

The study of aphrodisiacs is an overlooked area of global history which this article seeks to remedy by considering how such substances were commercially traded and how medical knowledge of them was exchanged globally between 1600 and 1920. We show that the concept of ‘aphrodisiacs’ as a new nominal category of pharmacological substances came to be valued and defined in early modern Latin, English, Dutch, Swiss, and French medical sources in relation to concepts transformed from their origin in both the ancient Mediterranean world and in medieval Islamicate medicine. We then consider how the general idea of aphrodisiacs became widely discredited in mid-nineteenth-century scientific medicine until after the First World War in France and in the US, alongside their commercial proliferation in the context of new colonial trade exchanges between Europe, the US, Southeast Asia, Africa, India, and South America. In both examples, we propose that global entanglements played a significant role in both the cohesion and the discreditation of the medical category of aphrodisiacs.

Walking Together in Exile: Medical Moral Injury and the Clinical Chaplain

This article examines various sides of the recent discussion about establishing a medical category within the “moral injury” discourse. Essential differences between the nature and development of moral injury among physicians and combat veterans are acknowledged. Essential similarities are also explored. Case notes from a 3-year encounter between a clinical chaplain and a disoriented physician are offered as an illustration of how moral injury interventions with veteran populations can inform care for physicians experiencing burnout.

The (trans)formation of identity: The evolution of categories related to gender diversity in the case of trans-activism in Barcelona (1978–2010)

Since the emergence of trans-activism in Barcelona (pioneer in the Spanish context) in 1970, identity categories to refer to people who do not identify with the socially-assigned gender identity have experienced a major transformation. In this article, we analyse the evolution of identity categories related to gender diversity from 1978 to 2010 in order to recover the history of trans-activism and explore its specificities with regard to the hegemonic logic in other western countries. In the period analysed, five associations were identified and studied, revealing a trend that predominantly conceives identity categories in a fluid manner, contrary to the main trans-activism in western countries, which reinforced the medical category ‘transsexual’ in opposition to those of ‘homosexual’ and ‘transvestite’. Moreover, in this period, a profound change can be observed in the political subject (from trans-women working in sex work to middle-class trans-boys), as well as a transformation of alliances: from the rejection of trans-associations by gay and lesbian associations to the subsequent coalition and progressive rapprochement towards feminism.
