International policies guiding the selection, analysis, and clinical management of secondary findings from genomic sequencing: A systematic review.

Secondary findings (SFs) from genomic sequencing can have significant impacts on patient health, yet existing practices guiding their clinical investigation are inconsistent. We systematically reviewed existing SFs policies to identify variations and gaps in guidance. We cataloged and appraised international policies from academic databases (n = 5, inception-02/2022) and international human genetic societies (n = 64; inception-05/2022), across the continuum of SFs selection, analysis, and clinical management. We assessed quality using AGREE-II and interpreted results using qualitative description. Of the 63 SFs policies identified, most pertained to clinical management of SFs (98%; n = 62; primarily consent and disclosure), some guided SFs analysis (60%; n = 38), while fewer mentioned SFs selection (48%; n = 30). Overall, policies recommend (1) identifying clinically actionable, pathogenic variants with high positive predictive values for disease (selection), (2) bioinformatically filtering variants using evidence-informed gene lists (analysis), and (3) discussing with affected individuals the SFs identified, their penetrance, expressivity, medical implications, and management (clinical management). Best practices for SFs variant analysis, clinical validation, and follow-up (i.e., surveillance, treatment, etc.) were minimally described. Upon quality assessment, policies were highly rated for scope and clarity (median score, 69) but were limited by their rigor and applicability (median scores, 27 and 25). Our review represents a comprehensive international synthesis of policy guiding SFs across the continuum of selection, analysis, and clinical management. Our synthesis will help providers navigate critical decision points in SFs investigation, although significant work is needed to address gaps in SFs analysis, clinical validation, and follow-up processes and to support evidence-based practice.

The landscape of the methodology in drug repurposing using human genomic data: a systematic review.

The process of drug development is expensive and time-consuming. In contrast, drug repurposing can be introduced to clinical practice more quickly and at a reduced cost. Over the last decade, there has been a significant expansion of large biobanks that link genomic data to electronic health record data, public availability of various databases containing biological and clinical information and rapid development of novel methodologies and algorithms in integrating different sources of data. This review aims to provide a thorough summary of different strategies that utilize genomic data to seek drug-repositioning opportunities. We searched MEDLINE and EMBASE databases to identify eligible studies up until 1 May 2023, with a total of 102 studies finally included after two-step parallel screening. We summarized commonly used strategies for drug repurposing, including Mendelian randomization, multi-omic-based and network-based studies and illustrated each strategy with examples, as well as the data sources implemented. By leveraging existing knowledge and infrastructure to expedite the drug discovery process and reduce costs, drug repurposing potentially identifies new therapeutic uses for approved drugs in a more efficient and targeted manner. However, technical challenges when integrating different types of data and biased or incomplete understanding of drug interactions are important hindrances that cannot be disregarded in the pursuit of identifying novel therapeutic applications. This review offers an overview of drug repurposing methodologies, providing valuable insights and guiding future directions for advancing drug repurposing studies.

Tools to facilitate communication during physician-patient consultations in cancer care: An overview of systematic reviews.

Tools have been developed to facilitate communication and support information exchange between people diagnosed with cancer and their physicians. Patient-reported outcome measures, question prompt lists, patient-held records, tape recordings of consultations, decision aids, and survivorship care plans have all been promoted as potential tools, and there is extensive literature exploring their impact on patient outcomes. Eleven systematic reviews of studies evaluating tools to facilitate patient-physician communication were reviewed and summarized in this overview of systematic reviews. Across the systematic reviews, 87 publications reported on 84 primary studies involving 15,381 participants. Routine use of patient-reported outcome measures and feedback of results to clinicians can improve pain management, physician-patient communication, and symptom detection and control; increase utilization of supportive care; and increase patient involvement in care. Question prompt lists can increase the number of questions asked by patients without increasing consultation length and may encourage them to reflect and plan questions before the consultation. There is limited benefit in audio recording consultations or using patient-held records during consultations. Physicians should be supported by adequately resourced health services to respond effectively to the range of clinical and broader patient needs identified through the routine use of tools to facilitate communication.

The American Society for Microbiology collaboration with the CDC Laboratory Medicine Best Practices initiative for evidence-based laboratory medicine.

SUMMARYClinical medicine has embraced the use of evidence for patient treatment decisions; however, the evaluation strategy for evidence in laboratory medicine practices has lagged. It was not until the end of the 20th century that the Institute of Medicine (IOM), now the National Academy of Medicine, and the Centers for Disease Control and Prevention, Division of Laboratory Systems (CDC DLS), focused on laboratory tests and how testing processes can be designed to benefit patient care. In collaboration with CDC DLS, the American Society for Microbiology (ASM) used an evidence review method developed by the CDC DLS to develop a program for creating laboratory testing guidelines and practices. The CDC DLS method is called the Laboratory Medicine Best Practices (LMBP) initiative and uses the A-6 cycle method. Adaptations made by ASM are called Evidence-based Laboratory Medicine Practice Guidelines (EBLMPG). This review details how the ASM Systematic Review (SR) Processes were developed and executed collaboratively with CDC's DLS. The review also describes the ASM transition from LMBP to the organization's current EBLMPG, maintaining a commitment to working with agencies in the U.S. Department of Health and Human Services and other partners to ensure that EBLMPG evidence is readily understood and consistently used.

Sodium-glucose cotransporter-2 inhibitors and their potential role in dementia onset and cognitive function in patients with diabetes mellitus: a systematic review and meta-analysis.

This systematic review and meta-analysis aimed to determine the association between the use of sodium-glucose cotransporter 2 (SGLT-2) inhibitors and dementia onset as well as cognitive function in patients with diabetes mellitus. We comprehensively searched the MEDLINE, Embase, and CENTRAL databases to select relevant studies published up to August 2023. The use of SGLT-2 inhibitors significantly lowers dementia risk compared to SGLT-2i non-users (Hazard ratio: 0.68, 95 % CI: 0.50-0.92). Furthermore, our findings indicated a positive effect of SGLT-2 inhibitor use on cognitive function score improvement, as demonstrated by the standardized mean difference of 0.88 (95 % CI: 0.32-1.44), particularly among populations with mild cognitive impairment or dementia. This systematic review and meta-analysis indicate a potential role of SGLT-2 inhibitors in reducing the risk of dementia in patients with diabetes mellitus. These findings underscore the need for well-controlled large clinical trials and future research in this field.

Symptoms of mental disorders and oral contraception use: A systematic review and meta-analysis.

Worldwide, over 150 million adolescent and adult women use oral contraceptives (OC). An association between OC-use and the emergence of symptoms of mental disorders has been suggested. This systematic review and meta-analysis provide an overview of published research regarding symptoms of mental disorders in association with OC-use, factoring the influence of OC types, age of first-use, duration of OC-intake, and previous diagnoses of mental disorders. A systematic literature search was conducted between June-July 2022. 22 studies were included. While most found no significant OC-use effects on mental symptoms, some hinted at OCs as a potential risk. The existing evidence regarding the potential link between progestin-only OC-use and an elevated risk of mental symptoms in comparison to combined OC-use remains inconclusive. However, due to emerging indications suggesting that the formulation of OC might play a role in mental health outcomes, this topic warrants further investigation. Moreover, indications of an increased risk for depressive symptoms in adolescent OC-users should be noted. Hence, while general population effects seem unlikely, they cannot be completely disregarded. The decision on OC-use should depend on the patient's medical history and should be re-evaluated regularly.

Application of deep learning in cancer epigenetics through DNA methylation analysis.

DNA methylation is a fundamental epigenetic modification involved in various biological processes and diseases. Analysis of DNA methylation data at a genome-wide and high-throughput level can provide insights into diseases influenced by epigenetics, such as cancer. Recent technological advances have led to the development of high-throughput approaches, such as genome-scale profiling, that allow for computational analysis of epigenetics. Deep learning (DL) methods are essential in facilitating computational studies in epigenetics for DNA methylation analysis. In this systematic review, we assessed the various applications of DL applied to DNA methylation data or multi-omics data to discover cancer biomarkers, perform classification, imputation and survival analysis. The review first introduces state-of-the-art DL architectures and highlights their usefulness in addressing challenges related to cancer epigenetics. Finally, the review discusses potential limitations and future research directions in this field.

Recent application of artificial intelligence on histopathologic image-based prediction of gene mutation in solid cancers.

PURPOSE: Evaluation of genetic mutations in cancers is important because distinct mutational profiles help determine individualized drug therapy. However, molecular analyses are not routinely performed in all cancers because they are expensive, time-consuming and not universally available. Artificial intelligence (AI) has shown the potential to determine a wide range of genetic mutations on histologic image analysis. Here, we assessed the status of mutation prediction AI models on histologic images by a systematic review. METHODS: A literature search using the MEDLINE, Embase and Cochrane databases was conducted in August 2021. The articles were shortlisted by titles and abstracts. After a full-text review, publication trends, study characteristic analysis and comparison of performance metrics were performed. RESULTS: Twenty-four studies were found mostly from developed countries, and their number is increasing. The major targets were gastrointestinal, genitourinary, gynecological, lung and head and neck cancers. Most studies used the Cancer Genome Atlas, with a few using an in-house dataset. The area under the curve of some of the cancer driver gene mutations in particular organs was satisfactory, such as 0.92 of BRAF in thyroid cancers and 0.79 of EGFR in lung cancers, whereas the average of all gene mutations was 0.64, which is still suboptimal. CONCLUSION: AI has the potential to predict gene mutations on histologic images with appropriate caution. Further validation with larger datasets is still required before AI models can be used in clinical practice to predict gene mutations.

Clinical manifestations of dengue, Zika and chikungunya in the Pacific Islands: A systematic review and meta-analysis.

Dengue, Zika and chikungunya outbreaks pose a significant public health risk to Pacific Island communities. Differential diagnosis is challenging due to overlapping clinical features and limited availability of laboratory diagnostic facilities. There is also insufficient information regarding the complications of these arboviruses, particularly for Zika and chikungunya. We conducted a systematic review and meta-analysis to calculate pooled prevalence estimates with 95% confidence intervals (CI) for the clinical manifestations of dengue, Zika and chikungunya in the Pacific Islands. Based on pooled prevalence estimates, clinical features that may help to differentiate between the arboviruses include headache, haemorrhage and hepatomegaly in dengue; rash, conjunctivitis and peripheral oedema in Zika; and the combination of fever and arthralgia in chikungunya infections. We estimated that the hospitalisation and mortality rates in dengue were 9.90% (95% CI 7.67-12.37) and 0.23% (95% CI 0.16-0.31), respectively. Severe forms of dengue occurred in 1.92% (95% CI 0.72-3.63) of reported cases and 23.23% (95% CI 13.58-34.53) of hospitalised patients. Complications associated with Zika virus included Guillain-Barré syndrome (GBS), estimated to occur in 14.08 (95% CI 11.71-16.66) per 10,000 reported cases, and congenital brain malformations such as microcephaly, particularly with first trimester maternal infection. For chikungunya, the hospitalisation rate was 2.57% (95% CI 1.30-4.25) and the risk of GBS was estimated at 1.70 (95% CI 1.06-2.48) per 10,000 reported cases. Whilst ongoing research is required, this systematic review enhances existing knowledge on the clinical manifestations of dengue, Zika and chikungunya infections and will assist Pacific Island clinicians during future arbovirus outbreaks.

Risk of kidney and liver diseases after COVID-19 infection: A systematic review and meta-analysis.

COVID-19 is not only associated with substantial acute liver and kidney injuries, but also with an elevated risk of post-acute sequelae involving the kidney and liver system. We aimed to investigate whether COVID-19 exposure increases the long-term risk of kidney and liver disease, and what are the magnitudes of these associations. We searched PubMed, Embase, Web of Science, ClinicalTrials.gov, and the Living Overview of the Evidence COVID-19 Repository for cohort studies estimating the association between COVID-19 and kidney and liver outcomes. Random-effects meta-analyses were performed to combine the results of the included studies. We assessed the certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation approach. Fifteen cohort studies with more than 32 million participants were included in the systematic review COVID-19 was associated with a 35% greater risk of kidney diseases (10 more per 1000 persons; low certainty evidence) and 54% greater risk of liver disease (3 more per 1000 persons; low certainty evidence). The absolute increases due to COVID-19 for acute kidney injury, chronic kidney disease, and liver test abnormality were 3, 8, and 3 per 1000 persons, respectively. Subgroup analyses found no differences between different type of kidney and liver diseases. The findings provide further evidence for the association between COVID-19 and incident kidney and liver conditions. The absolute magnitude of the effect of COVID-19 on kidney and liver outcomes was, however, relatively small.

The Impact of HIV Upon the PCI Results: A Systematic Review and Meta-Analysis.

The aim of this systematic review and meta-analysis was to comprehensively evaluate the latest evidences and summarise the impact of HIV on PCI outcomes. A PRISMA guided literature search was conducted on 14 February 2024 in Web of Science, PubMed, Virtual Health Library, Google Scholar and Scopus. We searched with the term '("percutaneous coronary intervention" OR "PCI") AND ("human immunodeficiency virus" OR "HIV" OR "acquired immunodeficiency syndrome" OR "AIDS")' after selecting the keywords from randomly chosen included papers. We included 8 papers of 781 screened records. HIV (+) patients had significant in-hospital, 1-year and overall (event at the last follow up point) all-cause mortality compared to HIV (-) group (OR: 1.73, 95%CI: 1.57-1.90, p < 0.01), (OR: 1.39, 95%CI: 1.07-1.81, p = 0.01) and (OR: 1.69, 95%CI: 1.55-1.85, p < 0.01), respectively. HIV (+) patients had significantly higher odds of developing MACE (OR: 1.35, 95%CI: 1.12-1.62, p = 0.001) compared to the HIV (-) group. No differences between both groups were detected regarding in-hospital and overall CV mortality, TVR, TLR, post-PCI TIMI grade 3 flow, cerebrovascular accidents and recurrent coronary events (p > 0.05). Our study revealed that people with HIV who underwent PCI in this modern era may have worse short and long-term PCI outcomes. This finding highlights the need for specialised cardiovascular care protocols for the HIV population. However, enhanced clinical management and preventative measures are imperative to improve PCI success rates in patients with HIV.

An overview of SARS-CoV2 natural infections in companion animals: A systematic review of the current evidence.

This systematic review provides a comprehensive overview of natural SARS-CoV-2 infections in companion animals. The findings show that these infections are relatively rare. Among the examined dogs, only 1.32% tested positive for SARS-CoV-2, while for cats, the rate was 1.55%. Infections in rabbits and ferrets were even less common, at less than 1%. These results support previous research indicating the infrequency of natural infections in companion animals. The review also includes updated studies that involved various pets, such as cats, dogs, ferrets, and rabbits. The majority of the studies analyzed were primarily concerned with screening pets that visited veterinary clinics, regardless of whether they showed any specific signs of SARS-CoV-2 infection. Only a limited number of studies investigated infections in animals suspected of being in contact with owners or other animals that had COVID-19 or were exhibiting symptoms. The most common variant identified among the SARS-CoV-2 variants in the reviewed studies was B.1.1.7 (alpha), followed by B.1.617.2 (delta), B.1.526 (Iota), and others. The emergence of these variants raises concerns about their potential for increased transmissibility and virulence, highlighting the importance of ongoing monitoring of SARS-CoV-2 infections in both humans and animals. Furthermore, most of the reviewed studies indicated that infected pets either showed no symptoms or experienced mild symptoms. This aligns with previous reports suggesting that animals infected with SARS-CoV-2 generally have less severe illness compared to humans. However, it is essential to recognize the possibility of severe illness or death in animals, particularly those with underlying health conditions. Continuous surveillance of SARS-CoV-2 infections in companion animals is crucial for better understanding the virus's epidemiology in animals and developing effective strategies to protect both animal and human health.

Global seroprevalence and prevalence of infection of influenza in dogs (Canis familiaris): A systematic review and meta-analysis.

Influenza in dogs holds considerable public health significance due to their close companionship with humans, yet several facets of this phenomenon remain largely unexplored. This study undertook a systematic review and meta-analysis of observational studies to gauge the global seroprevalence of influenza in dogs. We also assessed whether pet dogs exhibited a higher seroprevalence of influenza compared to non-pet dogs, explored seasonal variations in seroprevalence, scrutinised the design and reporting standards of existing studies, and elucidated the geographical distribution of canine influenza virus (cIV). A comprehensive analysis of 97 studies spanning 27 countries revealed that seroprevalence of various influenza strains in dogs consistently registered below 10% and exhibited relative stability over the past decade. Significantly, we noted that seroprevalence of human influenza virus was notably higher in pet dogs compared to their non-pet counterparts, whereas seroprevalence of other influenza strains remained relatively uniform among both categories of dogs. Seasonal variations in seroprevalence of cIV were not observed. In summary, our findings indicated the global circulation of cIV strains H3N2 and H3N8, with other strains primarily confined to China. Given the lack of reported cases of the transmission of cIV from dogs to humans, our findings suggest a higher risk of reverse zoonosis than zoonosis. Finally, we strongly advocate for standardised reporting guidelines to underpin future canine influenza research endeavours.

Systematic Review of the Efficacy and Safety of RSV-Specific Monoclonal Antibodies and Antivirals in Development.

Respiratory syncytial virus (RSV) is a leading cause of acute respiratory infection amongst all ages, causing a significant global health burden. Preventative and therapeutic options for RSV infection have long been under development, and recently, several widely-publicised vaccines targeting older adult and maternal populations have become available. Promising monoclonal antibody (mAb) and antiviral (AV) therapies are also progressing in clinical trials, with the prophylactic mAb nirsevimab recently approved for clinical use in infant populations. A systematic review on current progress in this area is lacking. We performed a systematic literature search (PubMed, Embase, Web of Science, ClinicalTrials.gov, EudraCT, ANZCTR-searched Nov 29th, 2023) to identify studies on all RSV-specific mAbs and AV therapies that has undergone human clinical trials since year 2000. Data extraction focused on outcomes related to the therapeutic efficacy and safety of the intervention on trial, and all studies were graded against the OCEBM Levels of Evidence Table. Results from 59 studies were extracted, covering efficacy and safety data on six mAbs (motavizumab, motavizumab-YTE, nirsevimab, ALX-0171, suptavumab, clesrovimab) and 12 AV therapies (ALN-RSV01, RSV604, presatovir, MDT-637, lumicitabine, IFN-α1b, rilematovir, enzaplatovir, AK0529, sisunatovir, PC786, EDP-938). Of the mAbs reviewed, nirsevimab and clesrovimab hold considerable promise. The timeline for RSV-specific AV availability is less advanced, although EDP-938 and AK0529 have reported promising phase 2 efficacy and safety data. Moving forward, passive immunisation and treatment options for RSV infection will play a significant role in reducing the health burden of RSV, complementing recent advancements in vaccine development.

Prevalence and factors associated with viral non-suppression in people living with HIV receiving antiretroviral therapy in sub-Saharan Africa: A systematic review and meta-analysis.

Despite advances in HIV treatment, the burden of viral non-suppression (VNS) remains a treatment success concern, particularly in Sub-Saharan African (SSA) countries. We determined the prevalence and factors associated with VNS for people living with HIV (PLHIV) receiving antiretroviral therapy (ART). This review, registered with PROSPERO (CRD42023470234), conducted an extensive search for evidence, focusing on PLHIV living in SSA on ART from the year 2000 to 19th October 2023, across databases including PubMed/MEDLINE, Embase, Web of Science, and Scopus. A total of 2357 articles were screened, from which 32 studies met the criteria for the final analysis, involving 756,620 PLHIV of all ages. The pooled prevalance for VNS was found to be 20.0% (95% CI: 15.43%-25.52%, I2 = 100%, p-value <0.01) Children and adolescents demonstrated the highest prevalence of VNS (viral load ≥1000 copies/mL) at 27.98% (95% CI: 21.91%-34.97%, I2 = 94%, p-value <0.01). The study revealed various factors associated with increased odds (risk) of VNS, p-value <0.05. These factors encompassed socio-demographics such as sex, age, education level, and marital status. Additionally, aspects related to HIV care, such as the facility attended, HIV status disclosure and adherence exhibited higher odds of VNS. Suboptimal ART adherence, longer duration on ART, socio-economic factors, lack of family and social support, presence of co-morbidities, advanced WHO HIV clinical stage, ART regimens, lower CD4+ count, abnormal body mass index, history of treatment interruptions, and progression of HIV illness were associated with VNS. Furthermore, behavioural/psychological factors including depression, substance use, negative perceptions towards ART, experiences of abuse, alcohol use, stigma, and certain patterns of sexual behaviour were also identified as factors for VNS. The occurrence of two VNS to every ten PLHIV on ART poses a threat to the progress made towards reaching the third 95% UNAIDS target in SSA. Additionally, these findings highlight the intricate interplay of various factors, encompassing patient characteristics, behavioural patterns, sociocultural influences, and pharmacological factors, all impacting VNS among PLHIV. Recognising its multifaceted nature, we recommend designing and implementing high impact interventions to effectively address VNS in SSA.

A methodological framework for rigorous systematic reviews: Tailoring comprehensive analyses to clinicians and healthcare professionals.

Systematic reviews represent a fundamental study design, providing the highest level of evidence across diverse research inquiries, encompassing both public health and clinical research and practice. However, for healthcare professionals, the process of selecting, synthesizing, and interpreting evidence can be challenging, and requires specialized skills. Therefore, it is imperative to explore innovative solutions aimed at simplifying and making the traditional systematic review process more accessible while ensuring the validity and reliability of results. In this perspective, our research objective is to develop a systematic review framework that, while maintaining a rigorous methodological approach, streamlines the process for healthcare professionals. This study describes such approach in every phase, from the collection of evidence to the writing of the text, creating a guide for the healthcare professional who approaches this type of research. The qualitative and organizational analysis tools are also described, providing useful information for the use of non-paid programs. This systematic review aims to develop a framework with a rigorous methodological approach that allows simplify the process for clinicians and healthcare professionals. The implementation of this methodology in clinical practice offers new perspectives to ensure a thoughtful consideration and application of scientific evidence and opens the way to innovative and easily accessible solutions to facilitate the conduct of systematic reviews in the clinical care setting.

International treaties have mostly failed to produce their intended effects.

There are over 250,000 international treaties that aim to foster global cooperation. But are treaties actually helpful for addressing global challenges? This systematic field-wide evidence synthesis of 224 primary studies and meta-analysis of the higher-quality 82 studies finds treaties have mostly failed to produce their intended effects. The only exceptions are treaties governing international trade and finance, which consistently produced intended effects. We also found evidence that impactful treaties achieve their effects through socialization and normative processes rather than longer-term legal processes and that enforcement mechanisms are the only modifiable treaty design choice with the potential to improve the effectiveness of treaties governing environmental, human rights, humanitarian, maritime, and security policy domains. This evidence synthesis raises doubts about the value of international treaties that neither regulate trade or finance nor contain enforcement mechanisms.

The win ratio in cardiology trials: lessons learnt, new developments, and wise future use.

The win ratio method for analysing a composite clinical hierarchy of outcomes is growing in popularity especially in cardiovascular trials. This article gives a perspective on its use so far and the issues derived from that experience. Specifically, it focuses on the limitations of a conventional composite outcome; how does the win ratio work, what does it mean, and how to display its findings; guidance on choosing an appropriate clinical hierarchy of outcomes including clinical events, quantitative outcomes, and other options; the additional value of the win difference as a measure of absolute benefit: extension to stratified win ratio, subgroup analysis, matched win ratio, and covariate adjustment; determining trial size for a win ratio outcome; specific insights such as adaptive designs, use of repeat events, and use of margins and time averages for quantitative outcomes; a critique of potential misuses; availability of statistical software; and a statistical appendix on the methodological details. Throughout, each principle is illustrated by examples from specific cardiology trials. The article concludes with a set of recommendations for future use of the win ratio.

Sex differences in treatment of familial hypercholesterolaemia: a meta-analysis.

BACKGROUND AND AIMS: Familial hypercholesterolaemia (FH) is a highly prevalent monogenic disorder characterized by elevated LDL cholesterol (LDL-C) levels and premature atherosclerotic cardiovascular disease. Sex disparities in diagnosis, lipid-lowering therapy, and achieved lipid levels have emerged worldwide, resulting in barriers to care in FH. A systematic review was performed to investigate sex-related disparities in treatment, response, and lipid target achievement in FH (PROSPERO, CRD42022353297). METHODS: MEDLINE, Embase, The Cochrane library, PubMed, Scopus, PsycInfo, and grey literature databases were searched from inception to 26 April 2023. Records were eligible if they described sex differences in the treatment of adults with FH. RESULTS: Of 4432 publications reviewed, 133 met our eligibility criteria. In 16 interventional clinical trials (eight randomized and eight non-randomized; 1840 participants, 49.4% females), there were no differences between males and females in response to fixed doses of lipid-lowering therapy, suggesting that sex was not a determinant of response. Meta-analysis of 25 real-world observational studies (129 441 participants, 53.4% females) found that females were less likely to be on lipid-lowering therapy compared with males (odds ratio .74, 95% confidence interval .66-.85). Importantly, females were less likely to reach an LDL-C < 2.5 mmol/L (odds ratio .85, 95% confidence interval .74-.97). Similarly, treated LDL-C levels were higher in females. Despite this, male sex was associated with a two-fold greater relative risk of major adverse cardiovascular events including myocardial infarction, atherosclerotic cardiovascular disease, and cardiovascular mortality. CONCLUSIONS: Females with FH were less likely to be treated intensively and to reach guideline-recommended LDL-C targets. This sex bias represents a surmountable barrier to clinical care.

Cardiovascular disease risk communication and prevention: a meta-analysis.

BACKGROUND AND AIMS: Knowledge of quantifiable cardiovascular disease (CVD) risk may improve health outcomes and trigger behavioural change in patients or clinicians. This review aimed to investigate the impact of CVD risk communication on patient-perceived CVD risk and changes in CVD risk factors. METHODS: PubMed, Embase, and PsycINFO databases were searched from inception to 6 June 2023, supplemented by citation analysis. Randomized trials that compared any CVD risk communication strategy versus usual care were included. Paired reviewers independently screened the identified records and extracted the data; disagreements were resolved by a third author. The primary outcome was the accuracy of risk perception. Secondary outcomes were clinician-reported changes in CVD risk, psychological responses, intention to modify lifestyle, and self-reported changes in risk factors and clinician prescribing of preventive medicines. RESULTS: Sixty-two trials were included. Accuracy of risk perception was higher among intervention participants (odds ratio = 2.31, 95% confidence interval = 1.63 to 3.27). A statistically significant improvement in overall CVD risk scores was found at 6-12 months (mean difference = -0.27, 95% confidence interval = -0.45 to -0.09). For primary prevention, risk communication significantly increased self-reported dietary modification (odds ratio = 1.50, 95% confidence interval = 1.21 to 1.86) with no increase in intention or actual changes in smoking cessation or physical activity. A significant impact on patients' intention to start preventive medication was found for primary and secondary prevention, with changes at follow-up for the primary prevention group. CONCLUSIONS: In this systematic review and meta-analysis, communicating CVD risk information, regardless of the method, reduced the overall risk factors and enhanced patients' self-perceived risk. Communication of CVD risk to patients should be considered in routine consultations.
