When and in what circumstances is patient-targeted googling acceptable for health and social care professionals? A narrative review and thematic analysis.

Background: Patient-targeted Googling (PTG) is the use of Internet search engines by care professionals to source information about their patients. Objective: To thematically analyse research evidence on PTG and explain what, why and how it can be used for the benefit of patient care. Methods: The Scale for the Assessment of Narrative Review articles was used as a reporting tool. Studies were identified via AMED, CINAHL, MEDLINE and APA PsycInfo, ProQuest, and grey literature via Google Scholar. Results: 19 studies were included, and content was thematically analysed. Themes included practitioner behaviours, attitudes and experience, the nature of online information, when PTG is not acceptable, when, why and how is PTG acceptable and the need for education and training on PTG. Discussion & conclusion: In the absence of professional guidance, it makes practical recommendations about why and in what circumstances can use patient-targeted Googling for the benefit of patient care.

Public interest and seasonal peaks for wisdom teeth related web inquiries - A google trends analysis.

Objective: The study aimed to analyze the public interest in wisdom teeth-related search terms as well as regional and seasonal trends based on information from the Google search engine. METHODS: With the help of the online search query tool, Google Trends, the public interest in the primary search term "wisdom teeth" for the timeframe between January 1st, 2004 and September 31st, 2021 was analyzed. To do so, a country-specific search was conducted in English-speaking countries (the USA, the UK, Canada, and Australia) in the northern and southern hemispheres. The extracted time series was examined for reliability, and a Cosinor analysis evaluated the statistical significance of seasonal interest peaks. RESULTS: The reliability of averaged time series data on the search term "wisdom teeth" was excellent in all examined countries. In all countries analyzed, "wisdom teeth removal" was one of the most common related search terms. Significant interest peaks for wisdom teeth-related search terms were found in Canada and the USA during summer (p < .001). In Canada and the USA, significant seasonal patterns with the highest interest during the summer months, could be displayed. CONCLUSION: This phenomenon could be caused by increased wisdom teeth-related complaints induced by seasonal climate changes.

Ostomy Information on the Internet-Is It Good Enough?

PURPOSE: The aim of this study was to determine which internet search engines and keywords patients with ostomies utilize, to identify the common websites using these terms, to determine what aspects of information they wanted, and to perform a quality and readability assessment for these websites. DESIGN: A cross-sectional survey of persons with ostomies to identify search engines and terms, followed by a structured assessment of the quality and readability of the identified web pages. SUBJECT AND SETTINGS: The sample comprised 20 hospitalized patients with ostomies cared for on a colorectal surgical ward of a tertiary care hospital located in Melbourne, Australia. There were 15 (75%) adult males and 5 (25%) adult females; their mean age was 52.2 years. Participants were surveyed between August and December 2020. METHODS: Patients with newly formed ostomies were surveyed about which search engines and keywords they would use to look for information and for which questions regarding ostomies they wanted answers. In addition, 2 researchers then performed independent searches using the search terms identified by patient participants. These searches were conducted in August 2021, with the geographical location set to Australia. The quality of the websites was graded using the DISCERN, Ensuring Quality Information for Patients, and Quality Evaluation Scoring Tool scoring assessments, and their readability was graded using the Flesch Reading Ease Score tool. RESULTS: Participants used Google as their primary search engine. Four keywords/phrases were identified: stoma for bowel surgery, ileostomy, colostomy, and caring for stoma. Multiple web pages were identified, 8 (21%) originated from Australia, 7 (18%) were from the United Kingdom, and 23 (61%) were from the United States. Most web pages lacked recent updates; only 18% had been undated within the last 12 months. The overall quality of the online information on ostomies was moderate with an average level of readability, deemed suitable for patient educational purposes. CONCLUSIONS: Information for persons living with an ostomy can be obtained from multiple web pages, and many sites have reasonable quality and are written at a suitable level. Unfortunately, these websites are rarely up-to-date and may contain advice that may not be applicable to individual patients.

Validated geographic search filters for bibliographic databases: a scoping review protocol.

OBJECTIVE: The purpose of this scoping review is to identify validated geographic search filters and report their methodology and performance measures. INTRODUCTION: Data on specific geographic areas can be required for evidence syntheses topics, such as the investigation of regional inequalities in health care or to answer context-specific epidemiological questions. Search filters are useful tools for reviewers aiming to identify publications with common characteristics in bibliographic databases. Geographic search filters limit the literature search results to a specific geographic feature (eg, a country or region). INCLUSION CRITERIA: We will include reports on validated geographic search filters that aim to identify research evidence about a defined geographic area (eg, a country/region or a group of countries/regions). METHODS: This review will be conducted in accordance with JBI methodology for scoping reviews. The literature search will be conducted in PubMed and Embase. The InterTASC Information Specialists' Sub-Group Search Filter resource and Google Scholar will also be searched. Reports published in any language, from database inception to the present, will be considered for inclusion. Two researchers will independently screen the title, abstract, and full text of the search results. A third reviewer will be consulted in the event of any disagreements. The data extraction will include study characteristics, basic characteristics of the geographical search filter (eg, country/region), and the methods used to develop and validate the search filter. The extracted data will be summarized narratively and presented in a table. REVIEW REGISTRATION: Open Science Framework https://osf.io/5czhs.

Online Interest for Electronic Cigarettes Using Google Trends in the UK: A Correlation Analysis.

BACKGROUND: Google Trends provides an easily accessible and cost-effective method of providing real-time insight into user interest. OBJECTIVE: to address the gap in UK prevalence data for e-cigarettes by analyzing Google Trends to identify correlations with official data from Action on Smoking and Health. The study further evaluates Google Trend's sensitivity to real-time events and the ability for predictive models to forecast future data based on Google Trends. METHODS: UK Google Trends data from 2012 to 2021 was analyzed to assess (a) the most popular electronic nicotine device terminology; (b) statistically significant points in time; (c) correlations between Relative Search Volumes and official reports on electronic cigarette use and (d) whether Google Trends could predict future patterns in data. These were achieved using Locally Weighted Scatterplot Smoothing regression, Pruned Exact Linear Time Method, cross correlation, and Autoregressive Integrated Moving Average algorithms respectively. RESULTS: "Vape" was revealed to be the most popular electronic nicotine device terminology with a correlation coefficient greater than +0.9 when compared to official electronic cigarette consumption data within a one-year timescale (lag 0). Results from ARIMA modeling were varied with the algorithms forecasted trends line occasionally lying outside of a 95% prediction interval. CONCLUSION: Google Trends may correspond to population-based prevalence of electronic cigarette use. The changing trends coincide with changing policy decisions. Google Trends based prediction for online interest in electronic cigarettes requires further validation so should currently be used in conjunction with other traditional methods of data collections.

Measuring environmental awareness: An analysis using google search data.

Environmental awareness is usually measured using surveys. This paper aims to offer an alternative measure: an Environmental Awareness Index (EAI) constructed using Google search data provided by Google Trends. The benefits of using Google search data over surveys are that (i) they are less costly to obtain, (ii) they are available at high frequency, and (iii) they cover countries where no surveys are available. To test the validity of the proposed EAI, this study empirically assesses the impact of the computed index on individuals' pro-environmental behaviors using the Special Eurobarometer: Attitudes of European citizens towards the Environment data. Results show that the EAI is positively related to pro-environmental behaviors with a statistical significance at the one percent level. This finding stays robust in pooled OLS as well as in panel regression analysis when GDP, mean years of schooling, and population are included as control variables and when time-fixed effects are introduced. Further, the results confirm that environmental awareness is not stable over time and underline the importance of having a timely measure of environmental awareness at hand. Finally, the findings offer several practical implications for managers and policymakers, who will be able to use a timely measure of environmental awareness, assess and measure the impact of their policies aiming to raise environmental awareness as well as depict the type of behavior influenced by their policies.

MS Annika 2.0 Identifies Cross-Linked Peptides in MS2-MS3-Based Workflows at High Sensitivity and Specificity.

Cross-linking mass spectrometry has become a powerful tool for the identification of protein-protein interactions and for gaining insight into the structures of proteins. We previously published MS Annika, a cross-linking search engine which can accurately identify cross-linked peptides in MS2 spectra from a variety of different MS-cleavable cross-linkers. In this publication, we present MS Annika 2.0, an updated version implementing a new search algorithm that, in addition to MS2 level, only supports the processing of data from MS2-MS3-based approaches for the identification of peptides from MS3 spectra, and introduces a novel scoring function for peptides identified across multiple MS stages. Detected cross-links are validated by estimating the false discovery rate (FDR) using a target-decoy approach. We evaluated the MS3-search-capabilities of MS Annika 2.0 on five different datasets covering a variety of experimental approaches and compared it to XlinkX and MaXLinker, two other cross-linking search engines. We show that MS Annika detects up to 4 times more true unique cross-links while simultaneously yielding less false positive hits and therefore a more accurate FDR estimation than the other two search engines. All mass spectrometry proteomics data along with result files have been deposited to the ProteomeXchange consortium via the PRIDE partner repository with the dataset identifier PXD041955.

Mistle: bringing spectral library predictions to metaproteomics with an efficient search index.

MOTIVATION: Deep learning has moved to the forefront of tandem mass spectrometry-driven proteomics and authentic prediction for peptide fragmentation is more feasible than ever. Still, at this point spectral prediction is mainly used to validate database search results or for confined search spaces. Fully predicted spectral libraries have not yet been efficiently adapted to large search space problems that often occur in metaproteomics or proteogenomics. RESULTS: In this study, we showcase a workflow that uses Prosit for spectral library predictions on two common metaproteomes and implement an indexing and search algorithm, Mistle, to efficiently identify experimental mass spectra within the library. Hence, the workflow emulates a classic protein sequence database search with protein digestion but builds a searchable index from spectral predictions as an in-between step. We compare Mistle to popular search engines, both on a spectral and database search level, and provide evidence that this approach is more accurate than a database search using MSFragger. Mistle outperforms other spectral library search engines in terms of run time and proves to be extremely memory efficient with a 4- to 22-fold decrease in RAM usage. This makes Mistle universally applicable to large search spaces, e.g. covering comprehensive sequence databases of diverse microbiomes. AVAILABILITY AND IMPLEMENTATION: Mistle is freely available on GitHub at https://github.com/BAMeScience/Mistle.

Users choose to engage with more partisan news than they are exposed to on Google Search.

If popular online platforms systematically expose their users to partisan and unreliable news, they could potentially contribute to societal issues such as rising political polarization1,2. This concern is central to the 'echo chamber'3-5 and 'filter bubble'6,7 debates, which critique the roles that user choice and algorithmic curation play in guiding users to different online information sources8-10. These roles can be measured as exposure, defined as the URLs shown to users by online platforms, and engagement, defined as the URLs selected by users. However, owing to the challenges of obtaining ecologically valid exposure data-what real users were shown during their typical platform use-research in this vein typically relies on engagement data4,8,11-16 or estimates of hypothetical exposure17-23. Studies involving ecological exposure have therefore been rare, and largely limited to social media platforms7,24, leaving open questions about web search engines. To address these gaps, we conducted a two-wave study pairing surveys with ecologically valid measures of both exposure and engagement on Google Search during the 2018 and 2020 US elections. In both waves, we found more identity-congruent and unreliable news sources in participants' engagement choices, both within Google Search and overall, than they were exposed to in their Google Search results. These results indicate that exposure to and engagement with partisan or unreliable news on Google Search are driven not primarily by algorithmic curation but by users' own choices.

Analysis of google trends and search results for ophthalmic symptoms of monkeypox.

PURPOSE: In July 2022, the World Health Organization (WHO) declared monkeypox virus's global spread a "public health emergency of international concern." About a quarter of monkeypox cases feature ophthalmic symptoms. We assessed trends in worldwide search interest in monkeypox ophthalmic involvement and inclusion in online search engine queries. METHODS: The following keywords were searched on Google Trends from April 1, 2022, to August 12, 2022: monkeypox + eye, pink eye, eye infection, eyelid, vision, blurry vision, vision loss, blindness, eye symptoms, eye problems, eye pain, eye redness, conjunctivitis, conjunctiva, cornea, keratitis, corneal ulcer, and blepharitis. We analyzed trends, correlated search interest with case count data, and compared popularity of search terms via nonparametric Mann-Whitney-U analysis. Inclusion of ophthalmic symptoms in Google search results for "monkeypox symptoms" was assessed. RESULTS: "Monkeypox eye" had the highest average search interest worldwide and in the United States. Search interest peaked between mid-May and late July 2022. When compared to interest in "monkeypox rash," the most searched monkeypox symptom, the average interest in "monkeypox eye" was lower (p < 0.01). Of the first 50 results from the Google search of "monkeypox symptoms," 10/50 (20%) mentioned ophthalmic symptoms. 6/50 (12%) mentioned the eye as a route of virus transmission. CONCLUSION: Search interest in monkeypox ophthalmic symptoms corresponds with geographic and temporal trends, i.e., timing and location of the first reported non-endemic cases and WHO announcement. Although ophthalmic symptoms are not as widely searched currently, inclusion in public health messaging is key for diagnosis, appropriate management, and reduction of further transmission.

Comparison of Database Searching Programs for the Analysis of Single-Cell Proteomics Data.

Single-cell proteomics is emerging as an important subfield in the proteomics and mass spectrometry communities, with potential to reshape our understanding of cell development, cell differentiation, disease diagnosis, and the development of new therapies. Compared with significant advancements in the "hardware" that is used in single-cell proteomics, there has been little work comparing the effects of using different "software" packages to analyze single-cell proteomics datasets. To this end, seven popular proteomics programs were compared here, applying them to search three single-cell proteomics datasets generated by three different platforms. The results suggest that MSGF+, MSFragger, and Proteome Discoverer are generally more efficient in maximizing protein identifications, that MaxQuant is better suited for the identification of low-abundance proteins, that MSFragger is superior in elucidating peptide modifications, and that Mascot and X!Tandem are better for analyzing long peptides. Furthermore, an experiment with different loading amounts was carried out to investigate changes in identification results and to explore areas in which single-cell proteomics data analysis may be improved in the future. We propose that this comparative study may provide insight for experts and beginners alike operating in the emerging subfield of single-cell proteomics.

Implementing the MSFragger Search Engine as a Node in Proteome Discoverer.

Here, we describe the implementation of the fast proteomics search engine MSFragger as a processing node in the widely used Proteome Discoverer (PD) software platform. PeptideProphet (via the Philosopher tool kit) is also implemented as an additional PD node to allow validation of MSFragger open (mass-tolerant) search results. These two nodes, along with the existing Percolator validation module, allow users to employ different search strategies and conveniently inspect search results through PD. Our results have demonstrated the improved numbers of PSMs, peptides, and proteins identified by MSFragger coupled with Percolator and significantly faster search speed compared to the conventional SEQUEST/Percolator PD workflows. The MSFragger-PD node is available at https://github.com/nesvilab/PD-Nodes/releases/.

iBench: A ground truth approach for advanced validation of mass spectrometry identification method.

The discovery of many noncanonical peptides detectable with sensitive mass spectrometry inside, outside, and on cells shepherded the development of novel methods for their identification, often not supported by a systematic benchmarking with other methods. We here propose iBench, a bioinformatic tool that can construct ground truth proteomics datasets and cognate databases, thereby generating a training court wherein methods, search engines, and proteomics strategies can be tested, and their performances estimated by the same tool. iBench can be coupled to the main database search engines, allows the selection of customized features of mass spectrometry spectra and peptides, provides standard benchmarking outputs, and is open source. The proof-of-concept application to tryptic proteome digestions, immunopeptidomes, and synthetic peptide libraries dissected the impact that noncanonical peptides could have on the identification of canonical peptides by Mascot search with rescoring via Percolator (Mascot+Percolator).

Construction and validation of a COVID-19 pandemic trend forecast model based on Google Trends data for smell and taste loss.

Aim: To explore the role of smell and taste changes in preventing and controlling the COVID-19 pandemic, we aimed to build a forecast model for trends in COVID-19 prediction based on Google Trends data for smell and taste loss. Methods: Data on confirmed COVID-19 cases from 6 January 2020 to 26 December 2021 were collected from the World Health Organization (WHO) website. The keywords "loss of smell" and "loss of taste" were used to search the Google Trends platform. We constructed a transfer function model for multivariate time-series analysis and to forecast confirmed cases. Results: From 6 January 2020 to 28 November 2021, a total of 99 weeks of data were analyzed. When the delay period was set from 1 to 3 weeks, the input sequence (Google Trends of loss of smell and taste data) and response sequence (number of new confirmed COVID-19 cases per week) were significantly correlated (P < 0.01). The transfer function model showed that worldwide and in India, the absolute error of the model in predicting the number of newly diagnosed COVID-19 cases in the following 3 weeks ranged from 0.08 to 3.10 (maximum value 100; the same below). In the United States, the absolute error of forecasts for the following 3 weeks ranged from 9.19 to 16.99, and the forecast effect was relatively accurate. For global data, the results showed that when the last point of the response sequence was at the midpoint of the uptrend or downtrend (25 July 2021; 21 November 2021; 23 May 2021; and 12 September 2021), the absolute error of the model forecast value for the following 4 weeks ranged from 0.15 to 5.77. When the last point of the response sequence was at the extreme point (2 May 2021; 29 August 2021; 20 June 2021; and 17 October 2021), the model could accurately forecast the trend in the number of confirmed cases after the extreme points. Our developed model could successfully predict the development trends of COVID-19. Conclusion: Google Trends for loss of smell and taste could be used to accurately forecast the development trend of COVID-19 cases 1-3 weeks in advance.

Variabilidad clínica del síndrome de ovario poliquístico / Clinical variability in polycystic ovary syndrome

Introducción: El síndrome de ovario poliquístico es la forma más común de anovulación crónica relacionada con exceso de andrógenos. La prevalencia oscila según el criterio diagnóstico utilizado entre 4-21 pòr ciento. Objetivo: Describir las características clínicas de las pacientes con síndrome de ovario poliquístico. Métodos: Se seleccionaron los consensos hasta ahora realizados y artículos originales de los último 10 años, disponibles en los siguientes buscadores: Pubmed, Medscape, Scielo, Bireme. Se consideraron otras publicaciones que por su importancia clínica no han sido replicados. Conclusiones: La variedad de fenotipos presentes en el SOP hace que las manifestaciones clínicas y factores de riesgo para otras morbilidades sean heterogéneas. La influencia que ejerce además su etiopatogenia, no completamente dilucidada, hace que el diagnóstico y por consiguiente el manejo actual de estas pacientes tenga un enfoque multidisciplinario, individualizado y enfocado a las prioridades e inconformidades que puedan afectar su calidad de vida(AU)

Introduction: Polycystic ovary syndrome (PCOS) is the most common form of chronic anovulation related to androgen excess. The prevalence ranges according to the diagnostic criteria used between 4-21 percent. Objective: To describe the clinical characteristics of patients with polycystic ovary syndrome. Methods: The consensuses and original articles of the last 10 years were selected, which were available in the following search engines: Pubmed, Medscape, Scielo, and Bireme. Other publications that due to their clinical importance have not been replicated were considered. Conclusions: The variety of phenotypes present in the polycystic ovary syndrome makes the clinical manifestations and risk factors for other morbidities heterogeneous. The influence exerted also by its etiopathogenesis, not completely elucidated, causes the diagnosis and therefore the current management of these patients to have a multidisciplinary approach which is individualized and focused on the priorities and nonconformities that may affect the patients' quality of life(AU)
