The serological diagnostic value of EBV-related IgA antibody panels for nasopharyngeal carcinoma: a diagnostic test accuracy meta-analysis

BackgroundNasopharyngeal carcinoma (NPC) is diagnosed relatively late and has a poor prognosis, requiring early detection to reduce the disease burden. This diagnostic test accuracy meta-analysis evaluated the serological diagnostic value of nine EBV-related IgA antibody panels (EBNA1-IgA, VCA-IgA, EA-IgA, Zta-IgA, EBNA1-IgA + VCA-IgA, VCA-IgA + EA-IgA, VCA-IgA + Rta-IgG, EBNA1-IgA + VCA-IgA + Zta-IgA and VCA-IgA + EA-IgA + Rta-IgG), aiming to identify suitable serological detection biomarkers for NPC screening.MethodsPubMed, Embase, China National Knowledge Infrastructure and Chinese BioMedical Literature Database were searched from January 1st, 2000 to September 30th, 2023, with keywords nasopharyngeal carcinoma, IgA, screening, early detection, early diagnosis, sensitivity and specificity. Articles on the diagnostic value of serum EBV-related IgA antibody panels for NPC were included. Study selection, data extraction, and quality assessment were performed independently by two researchers, and a third researcher was consulted in the case of disagreement. Bivariate models were used for statistical analysis. The quality of included studies was evaluated through Quality Assessment of Diagnostic Accuracy Studies tool (QUADAS-2).ResultsA total of 70 articles were included, involving 11 863 NPC cases and 34 995 controls. Among the nine EBV-related IgA antibody panels, EBNA1-IgA + VCA-IgA [0.928 (0.898, 0.950)], VCA-IgA + Rta-IgG [0.925 (0.890, 0.949)], EBNA1-IgA + VCA-IgA + Zta-IgA [0.962 (0.909, 0.985)] and VCA-IgA + EA-IgA + Rta-IgG [0.945 (0.918, 0.964)] demonstrated higher pooled sensitivity (95%CI). In terms of diagnostic odds ratio (DOR) (95%CI), EBNA1-IgA + VCA-IgA [107.647 (61.173, 189.430)], VCA-IgA + Rta-IgG [105.988 (60.118, 186.857)] and EBNA1-IgA + VCA-IgA + Zta-IgA [344.450 (136.351, 870.153)] showed superior performance. Additionally, the SROC curves for EBNA1-IgA + VCA-IgA and VCA-IgA + Rta-IgG were more favorable. However, publication bias was detected for VCA-IgA (P = 0.005) and EBNA1-IgA + VCA-IgA (P = 0.042).ConclusionsIn general, parallel detection of serum EBNA1-IgA, VCA-IgA and Zta-IgA antibodies using ELISA demonstrates better pooled sensitivity and DOR among the studied panels. In the cases where fewer indicators are used, serum VCA-IgA and EBNA1-IgA/Rta-IgG antibody panel exhibits a comparable performance.Trial registrationThe International Prospective Register of Systematic Reviews registration number: CRD42023426984, registered on May 28, 2023.

Diagnostic value of expressions of cancer stem cell markers for adverse outcomes of hepatocellular carcinoma and their associations with prognosis: A Bayesian network meta‑analysis.

The expression of cancer stem cell (CSC) markers adversely affect the survival prognosis of patients with hepatocellular carcinoma (HCC), but it is not clear which cancer stem cell marker has the best predictive effect on the survival prognosis and diagnostic value indicators of patients with HCC. Therefore, the present study performed a network meta-analysis to compare the prognostic and diagnostic value of the expressions of several CSC markers for patients with HCC and to identify the most efficient CSC marker. Studies on the associations of positive CSC markers with the overall survival (OS) rate, disease-free survival (DFS) rate, recurrence-free survival (RFS) rate, recurrence rate, differentiation, microvascular invasion and metastasis in patients with HCC were included in the network meta-analysis following searches on the PubMed, Embase, Elsevier and The Cochrane Library databases from January 1, 2013 to November 17, 2023. The Quality Assessment of Diagnostic Accuracy Studies-2 tool was used to assess the quality assessment of studies, and R (version 4.3.1), Stata (version 15.0) and Review Manager (version 5.3) were used for analysis. A total of 37 studies involving 3,980 participants were included. For patients with HCC, simultaneous positivity of cytokeratin 19 (CK19) and epithelial cell adhesion molecule (EpCAM) was the strongest predictor of the OS rate [surface under the cumulative ranking curve (SUCRA), 78.65%], positive keratin 19 (K19) was the strongest predictor of the RFS and DFS rates (SUCRA, 98.93 and 84.95%, respectively), and simultaneous positivity of EpCAM and cluster of differentiation (CD)90 was the strongest predictor of the recurrence rate (SUCRA, 5.61%). In addition, positivity of CD56, K19 and CD133 had the best diagnostic efficacy for poor differentiation [superiority index, 7.4498; 95% confidence interval (CI): 0.3333, 13.0000], microvascular invasion (superiority index, 8.4777; 95% CI: 0.2308, 17.0000), and metastasis (superiority index, 5.6097; 95% CI: 0.3333, 11.0000), respectively. In conclusion, no single CSC marker possessed the best predictive effect on all indexes of survival prognosis and diagnosis of patients with HCC. In terms of survival prognosis, simultaneous positivity of CK19 and EpCAM demonstrated the strongest predictive effect on the OS rate, suggesting an association with a low OS rate in patients with HCC; positive K19 revealed the strongest predictive effect on the RFS rate and DFS rate, suggesting an association with low RFS and DFS rates in patients with HCC; and simultaneous positivity of EpCAM and CD90 had the strongest predictive effect on the recurrence rate, suggesting a high recurrence rate in patients with HCC patients. In terms of diagnostic value, CD56, K19 and CD133 were the strongest predictors of poor differentiation, microvascular invasion and metastasis, respectively. In the future, well-designed randomized controlled trials are required to further confirm these findings.

Sexual and Reproductive Health Rights and Service Use among Undocumented Migrants in the EU: A Systematic Literature Review.

Most EU member states fail to provide essential sexual and reproductive health services to undocumented migrants, a vulnerable population facing limited access, utilization, and worse health-related outcomes. This study systematically reviewed the literature on access to and use of these services, as well as related health, economic, and migratory outcomes for undocumented migrants in the EU-EFTA region. The systematic review is reported based on the PRISMA 2020 checklist and includes 37 studies published between 2017 and 2024. Included studies were based upon original quantitative, qualitative, or mixed-methods data; conducted in one or more European countries; and published in one or more of the following languages: English, Spanish, French, Portuguese, or Romanian. A quality assessment was conducted using the CASP checklist for qualitative studies and the NHLBI Study Quality Assessment Tools for quantitative studies. The findings revealed numerous access barriers, including refusal of care, lack of knowledge about national healthcare schemes, bureaucratic hurdles, and affordability issues. Even when care was available, stigma, fear of deportation, socio-economic precarity, and abuse further hindered utilization. These barriers contributed to generally worse reproductive health outcomes for undocumented migrants in Europe, though the findings may not generalize to all EU-EFTA countries.

Diagnostic test accuracy of screening tools for the detection of neurocognitive disorders in older adults post-trauma: A protocol for a systematic review.

Neurocognitive disorders (NCDs), including delirium, cognitive impairment, or dementia are prevalent in up to 39% of older adults in acute care, particularly older trauma patients. Undiagnosed NCDs result in poor outcomes, such as increased incidence of depressive symptoms, longer length of stay, and mortality. This study aims to identify the diagnostic test accuracy of screening tools for the detection of NCDs in older trauma patients in acute settings. Systematic review protocol. Electronic databases (MEDLINE, Embase, CINAHL, PsycInfo, Cochrane Library) will be searched for journal articles. Search terms related to NCDs, delirium and cognitive screening tools, and diagnostic accuracy will be included. Cross-sectional, prospective, or retrospective cohort studies of adults aged ≥60 post-trauma, in an acute setting, will be included where the study aimed to validate a screening tool for detection of 1) delirium or 2) cognitive impairment, or dementia against a reference standard of a clinical decision, based on standardised diagnostic criteria or a validated tool. Two review authors will conduct study selection, data extraction, and appraisal. Data will be extracted based on the Preferred Reporting Items for a Systematic Review and Meta-analysis of Diagnostic Test Accuracy Studies (PRISMA-DTA) checklist. Studies will be assessed for methodological quality by two independent review authors using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. Narrative summaries will be generated describing risk of bias and concerns regarding applicability. Quantitative synthesis of study findings will be conducted. This systematic review will aim to identify screening tools with the best diagnostic accuracy for detection of 1) delirium and 2) cognitive impairment or dementia in adults aged ≥60 post-trauma in acute care settings. Results will inform clinical practice to enhance the probability of patients with NCDs receiving appropriate care and management.

Meta-analysis of the GALAD model for diagnosing primary hepatocellular carcinoma.

Ever since the GALAD (gender-age-Lens culinaris agglutinin-reactive alpha-fetoprotein-alpha-fetoprotein-des-gamma-carboxy prothrombin) logistic regression model was established to diagnose hepatocellular carcinoma (HCC), there has been no high-level evidence that evaluates and summarizes it. This meta-analysis was performed to assess the diagnostic ability of the GALAD model. The following databases were systematically searched for original diagnostic studies on HCC: PubMed, Embase, Medline, the Web of Science, Cochrane Library, China National Knowledge Infrastructure Wanfang (China), Wiper and the Chinese BioMedical Literature Database. After screening the search results according to our criteria, the Quality Assessment of Diagnostic Accuracy Studies 2 tool was used to evaluate the methodologic qualities, and statistical software were used to output the statistics. Ultimately, 10 studies were included and analyzed. The results revealed the pooled sensitivity and specificity of the GALAD model to be 0.86 (95% confidence interval [CI]: 0.82, 0.90) and 0.90 (95% CI: 0.87, 0.92), respectively, for all-stage HCC. The area under the curve (AUC) was 0.94. For early-stage HCC, the pooled sensitivity and specificity of the GALAD model were 0.83 (95% CI: 0.78, 0.87) and 0.81 (95% CI: 0.78, 0.83), respectively. The AUC was 0.90. This meta-analysis confirmed that the GALAD model has excellent diagnostic performance for early-stage and all-stage HCC and can maintain high sensitivity and specificity in early-stage HCC. Therefore, the GALAD model is qualified for screening early-stage canceration from chronic liver disease.

Prevalence of dental caries among children and adolescents with intellectual disability in India: A scoping review.

Children with intellectual and developmental disabilities are at a higher risk of developing dental caries. Few scoping reviews have been conducted in India to understand their issues. We aimed to summarise the distribution and risk factors of dental caries among children and adolescents with intellectual disabilities in India. A scoping review was conducted based on the Arksey O Malley framework. Quality assessment of studies, descriptive and thematic analyses were also conducted. We charted, collated, and summarised from four databases. Thirty-one studies met the study criteria consisting of children and adolescents with intellectual disabilities. Median caries prevalence was 70%, decayed missing and fIlled permenant teeth (DMFT) was 2.4, decayed missing and filled decidous teeth (dmft) was 2.36, and DMFS was 3.7. Major determinants were the severity of disability, socioeconomic status and parents' education. Oral care and dental visits were inadequate. Further exploration is required to improve access and reduce caries experience and prevalence among children with intellectual and developmental disabilities in India.

Effectiveness of mobile health for exercise promotion on cardiorespiratory fitness after a cancer diagnosis: A systematic review and meta-analysis.

Cancer survivors are at greater risk for cardiovascular-related mortality. Mobile health (mHealth) is an increasingly prevalent strategy for health promotion, but whether it consistently improves cardiorespiratory outcomes after a cancer diagnosis is unknown. We sought to determine the effectiveness of mHealth fitness/physical activity interventions on cardiorespiratory fitness outcomes among cancer patients and survivors. Leveraging MEDLINE/PubMed, Scopus, and ClinicalTrials.gov, we identified studies through May 2023. Included studies provided a quantitative evaluation of an mHealth intervention in a primary or secondary capacity on cardiorespiratory fitness (6-minute walk test, VO2max, 3-minute step test, or systolic blood pressure; or any mention of cardiac measure) and were meta-analyzed (using a random effects model) if they were a randomized controlled trial with sufficient quantitative information. Four coders were involved in applying inclusion/exclusion criteria, coding using a standardized data extraction sheet, and assessing study quality, with each study coded by at least two. Of 656 articles, nine (n = 392) met systematic review inclusion criteria (mean age range 19-62 years, 71.9% female, 60.9% breast cancer). Interventions included mobile apps (k = 6), smartwatches (k = 2), or a smartwatch plus a supplemental web/mobile/tablet app (k = 1); median duration of mHealth-use was 12 weeks. Seven (n = 341) fit criteria for meta-analysis. mHealth was associated with improved cardiorespiratory fitness (d = 0.33; 95% CI = 0.07-0.60) compared to a control group. Relationships remained after accounting for lipid-based outcomes (d = 0.30; 95% CI = 0.03-0.56). There was no evidence for heterogeneity or publication-bias. mHealth exercise interventions appear to be a viable strategy for improving cardiorespiratory fitness after a cancer diagnosis.

A Corpus-Assisted Study of Translation Criticism and Translation Quality Assessment

Translation criticism is mainly used to assess the quality and value of translation works, which is different from the traditional descriptive translation research. At present, some researchers often confuse the two, resulting in some corpus-based translation criticism stopping at the descriptive level and hindering the development of translation criticism. In view of this, this paper attempts to clarify the difference between corpus-assisted translation criticism and corpus translation studies, corpus translation criticism, and to explore the research scope of corpus-assisted translation criticism and refine its research design. In addition, the paper explores the development direction of this research paradigm and the limitations due to the constraints of current corpus technology and natural language processing technology. This paper aims to further promote the development of translation criticism in a scientific and systematic direction, so that scholars can more effectively assess translation quality and guide translation practice.

The cost-effectiveness of preventing, diagnosing, and treating postpartum haemorrhage: A systematic review of economic evaluations.

Postpartum haemorrhage (PPH) is an obstetric emergency. While PPH-related deaths are relatively rare in high-resource settings, PPH continues to be the leading cause of maternal mortality in limited-resource settings. We undertook a systematic review to identify, assess, and synthesise cost-effectiveness evidence on postpartum interventions to prevent, diagnose, or treat PPH. This systematic review was prospectively registered on PROSPERO (CRD42023438424). We searched Medline, Embase, NHS Economic Evaluation Database (NHS EED), EconLit, CINAHL, Emcare, Web of Science, and Global Index Medicus between 22 June 2023 and 11 July 2024 with no date or language limitations. Full economic evaluations of any postpartum intervention for prevention, detection, or management of PPH were eligible. Study screening, data extraction, and quality assessments (using the CHEC-E tool) were undertaken independently by at least 2 reviewers. We developed narrative syntheses of available evidence for each intervention. From 3,993 citations, 56 studies were included: 33 studies of preventative interventions, 1 study assessed a diagnostic method, 17 studies of treatment interventions, 1 study comparing prevention and treatment, and 4 studies assessed care bundles. Twenty-four studies were conducted in high-income countries, 22 in upper or lower middle-income countries, 3 in low-income countries, and 7 studies involved countries of multiple income levels. Study settings, methods, and findings varied considerably. Interventions with the most consistent findings were the use of tranexamic acid for PPH treatment and using care bundles. In both cases, multiple studies predicted these interventions would either result in better health outcomes and cost savings, or better health outcomes at acceptable costs. Limitations for this review include that no ideal setting was chosen, and therefore, a transferability assessment was not undertaken. In addition, some sources of study uncertainty, such as effectiveness parameters, were interrogated to a greater degree than other sources of uncertainty. In this systematic review, we extracted, critically appraised, and summarised the cost-effectiveness evidence from 56 studies across 16 different interventions for the prevention, diagnosis, and treatment of PPH. Both the use of tranexamic acid as part of PPH treatment, and the use of comprehensive PPH bundles for prevention, diagnosis, and treatment have supportive cost-effectiveness evidence across a range of settings. More studies utilizing best practice principles are required to make stronger conclusions on which interventions provide the best value. Several high-priority interventions recommended by World Health Organization (WHO) such as administering additional uterotonics, non-pneumatic anti-shock garment, or uterine balloon tamponade (UBT) for PPH management require robust economic evaluations across high-, middle-, and low-resource settings.

Assessment of Respiratory Health Implications of Vaping: A Systematic Review of Toxicity Mechanisms and Adverse Effects of Electronic Nicotine Delivery Systems.

E-cigarettes are thought to aid in tobacco smoking cessation, but there are concerns about their overall effectiveness and safety for the general population, particularly adults. This review aims to investigate the mechanisms of toxicity and adverse effects of e-cigarettes on the respiratory system, comparing these effects with those of conventional smoking. A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches were performed on PubMed, Embase, and the Cochrane Library using keywords, controlled vocabulary, and text words, with the following criteria: studies published in English from 2014 to 2024, open access, peer-reviewed, and full-text availability. Study selection, quality assessment, and data extraction were carried out by two independent reviewers. The Cochrane Risk of Bias 2.0 tool was used to evaluate the risk of bias in included randomized controlled trials, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool was employed to assess the strength of evidence and determine its generalizability. Electronic nicotine delivery systems (ENDS) have diverse mechanisms of toxicity, including inflammation, hypoxia, cardiovascular stress, and metabolic changes. Reported adverse effects include cough, throat irritation, nausea, and hemodynamic changes. However, ENDS are associated with fewer risks compared to conventional cigarette smoking. ENDS users experience fewer respiratory and cardiovascular issues and have lower levels of biomarkers such as NNAL and CO compared to traditional smokers. Additionally, ENDS are more effective than nicotine replacement therapy (nicotine patches) for smoking cessation, particularly in pregnant women. The side effects of ENDS and nicotine-free vaping are similar to those of conventional smoking in pregnant women, with the exception of a lower birth weight among newborns exposed to ENDS (p < 0.05). ENDS present a complex balance of benefits and risks regarding respiratory health. While there are adverse effects, ENDS are considered less detrimental than conventional smoking and a viable option for smoking cessation. Longitudinal studies are needed to evaluate their safety with long-term use (>16 weeks). Policymakers and health practitioners should use these findings to develop balanced public health policies that weigh the benefits of ENDS against potential health risks, enabling informed decision-making for users.

The Risks for HIV and Sexually Transmitted Infections Among Men Who Have Sex with Men Who Engage in Chemsex in Low- and Middle-Income Countries: A Mixed Methods Systematic Review and Meta-Analysis.

Chemsex, the use of drugs during and/or prior to sex, has been found to increase the risk of HIV and sexually transmitted infections (STI) among men who have sex with men (MSM). Many studies and reviews on chemsex were focused among MSM in high-income countries (HIC), with less attention given to understanding chemsex in low- and middle-income countries (LMIC). We estimated the prevalence of chemsex and its association with sexual risk behaviors, HIV, and STI among MSM in LMIC. We searched MEDLINE, Embase, GlobalHealth, PsychINFO, and CINAHL for quantitative, qualitative, and mixed-methods studies describing chemsex and its association with sexual risk behaviors, HIV, and STI among MSM in LMIC, published January 1, 2000-October 15, 2023. We used the Mixed Methods Appraisal Tool to assess study quality. We developed a narrative review and performed meta-analysis using a random effects model and the DerSimonian and Laird approach (PROSPERO #CRD42022339663). Thirty-two studies from LMIC, particularly from Asia, Africa, Latin America, and the Middle East, were included. MSM who engaged in chemsex had higher prevalence of condomless anal intercourse, group sex, having multiple sexual partners, and of HIV and STI compared to MSM who did not. We estimated a pooled prevalence for recent chemsex (≤ 12 months) of 16% (95% CI 11%-22%, τ = 0.01, I2 = 99.07%, p < 0.01). Chemsex and its associated behaviors are associated with HIV and STI among MSM in LMIC. Integration of harm reduction and sexual health services and structural changes could prevent HIV and STI prevention among MSM who engage in chemsex in LMIC.

Impaired glucose metabolism and the risk of vascular events and mortality after ischemic stroke: A systematic review and meta-analysis

BackgroundDiabetes mellitus (DM), prediabetes, and insulin resistance are highly prevalent in patients with ischemic stroke (IS). DM is associated with higher risk for poor outcomes after IS.ObjectiveInvestigate the risk of recurrent vascular events and mortality associated with impaired glucose metabolism compared to normoglycemia in patients with IS and transient ischemic attack (TIA).MethodsSystematic literature search was performed in PubMed, Embase, Cochrane Library on 21st March 2024 and via citation searching. Studies that comprised IS or TIA patients and exposures of impaired glucose metabolism were eligible. Study Quality Assessment Tool was used for risk of bias assessment. Covariate adjusted outcomes were pooled using random-effects meta-analysis.Main outcomesRecurrent stroke, cardiac events, cardiovascular and all-cause mortality and composite of vascular outcomes.ResultsOf 10,974 identified studies 159 were eligible. 67% had low risk of bias. DM was associated with an increased risk for composite events (pooled HR (pHR) including 445,808 patients: 1.58, 95% CI 1.34–1.85, I2 = 88%), recurrent stroke (pHR including 1.161.527 patients: 1.42 (1.29–1.56, I2 = 92%), cardiac events (pHR including 443,863 patients: 1.55, 1.50–1.61, I2 = 0%), and all-cause mortality (pHR including 1.031.472 patients: 1.56, 1.34–1.82, I2 = 99%). Prediabetes was associated with an increased risk for composite events (pHR including 8,262 patients: 1.50, 1.15–1.96, I2 = 0%) and recurrent stroke (pHR including 10,429 patients: 1.50, 1.18–1.91, I2 = 0), however, not with mortality (pHR including 9,378 patients, 1.82, 0.73–4.57, I2 = 78%). Insulin resistance was associated with recurrent stroke (pHR including 21,363 patients: 1.56, 1.19–2.05, I2 = 55%), but not with mortality (pHR including 21,363 patients: 1.31, 0.66–2.59, I2 = 85%).DiscussionDM is associated with a 56% increased relative risk of death after IS and TIA. Risk estimates regarding recurrent events are similarly high between prediabetes and DM, indicating high cardiovascular risk burden already in precursor stages of DM. There was a high heterogeneity across most outcomes.

Continuous glucose monitoring using machine learning models and IoT device data: A meta-analysis.

Machine learning offers diverse options for effectively managing blood glucose levels in diabetes patients. Selecting the right ML algorithm is critical given the array of available choices. Integrating data from IoT devices presents promising opportunities to enhance real-time blood glucose management models. This meta-analysis aims to evaluate the effectiveness of machine learning models utilizing IoT device data for predicting blood glucose levels. We systematically searched electronic databases for studies published between 2019 and 2023. We excluded studies lacking ML model derivation or performance metrics. The Quality Assessment of Diagnostic Accuracy Studies tool assessed study quality. Our primary outcomes compared ML models for BG level prediction across different prediction horizons (PHs). We analyzed ten eligible studies across prediction horizons of 15, 30, 45, and 60 minutes. ML models exhibited mean absolute RMSE values of 15.02 (SD 1.45), 21.488 (SD 2.92), 30.094 (SD 3.245), and 35.89 (SD 6.4) mg/dL, respectively. Random Forest demonstrated superior performance across these PHs. We observed significant heterogeneity across all subgroups, indicating diverse sources of variability. As the PH lengthened, the RMSE for blood glucose prediction by the ML model increased, with Random Forest showing the highest relative performance among the ML models.

TDMD: A Database for Dynamic Color Mesh Quality Assessment Study.

Dynamic colored meshes (DCM) are widely used in various applications. However, this kind of meshes may undergo different processes, such as compression or transmission, which can distort them and degrade their quality. To facilitate the development of objective metrics for DCMs and study the influence of typical distortions on their perception, we create the Tencent - Dynamic colored Mesh Database (TDMD) containing eight reference DCM objects with six typical distortions. Using processed video sequences (PVS) derived from the DCM, we conduct a large-scale subjective experiment that resulted in 303 distorted DCM samples with mean opinion scores, making the TDMD the largest available DCM database to our knowledge. This database enables us to study the impact of different types of distortion on human perception and offers recommendations for DCM compression and related tasks. Additionally, we have evaluated three types of state-of-the-art objective metrics on the TDMD, including image-based, point-based, and video-based metrics, on the TDMD. Our experimental results highlight the strengths and weaknesses of each metric, and we provide suggestions about the selection of metrics in practical DCM applications. The TDMD is publicly available at the following location: https://multimedia.tencent.com/resources/tdmd.

Effectiveness and Feasibility of Home-Based Palliative Care Interventions for Geriatric Oncology Patients: A Systematic Review Using Narrative Synthesis.

Due to an urgent need to develop palliative care services for geriatric patients with advanced cancer, an overview of available information regarding home-based palliative care interventions would be valuable. To summarize current literature for interventions targeted to homebound, older patients with incurable cancer, and investigate whether these patients can be benefited from home-based palliative care and achieve improved outcomes. A search strategy consisting of terms related to home care, palliation, oncology, and geriatrics was employed. A protocol following PRISMA guidelines was prospectively uploaded at PROSPERO (ID = CRD42023404675). Pubmed (MEDLINE), Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov, and Epistemonikos.org databases were searched from inception until the present day. Eligibility criteria were selected based on the research question, the population of interest, and the research design. The Risk of Bias Assessment Tool version 2 (RoB-2) was used to appraise study quality. A total of 10 articles including 871 patients (out of 1236 titles and 141 fully-reviewed texts) were selected. Four studies assessed exercise interventions, two evaluated multi-component home-care models, two focused on supervision services, and two had nutrition and activity components. Eight studies reported improved outcomes in either specified or mixed cancer geriatric populations. There is a scarcity of clinical trials regarding home-based palliative care for geriatric oncology patients, resulting in poor information and a lack of evidence. At-home interventions seem feasible and have a positive effect on pain management and functional status, but more high-quality studies are required.

Social Media Use and Well-Being: A Systematic Review and Meta-Analysis.

Prior research has investigated the link between social media use (SMU) and negative well-being. However, the connection with positive well-being has not been extensively studied, leading to a situation where there are inconsistent and inconclusive findings. This study fills this gap by examining the correlation between excessive and problematic SMU and subjective as well as psychological well-being (PWB). We conducted a systematic search across databases such as PubMed, Scopus, and Web of Science, and gray literature sources such as Research Gate and ProQuest, yielding 51 relevant studies for meta-analysis, encompassing a sample size of 680,506 individuals. Employing the Newcastle-Ottawa Scale, we assessed study quality, whereas statistical analysis was executed using R Studio. Excessive SMU showed no significant association with subjective (ES = 0.003, 95% confidence interval [95% CI]: -0.08, 0.09; p = 0.94, I2 = 95.8%, k =16) and PWB (ES = 0.16, 95% CI: -0.15, 0.45; p = 0.26, I2 = 98%, k = 7). Conversely, problematic SMU showed a negative correlation with subjective (ES = -0.14, 95% CI: -0.20, -0.09; p = 0.00, I2 = 93.3%, k = 25) and PWB (ES = -0.19, 95% CI: -0.31, -0.06; p = 0.01, I2 = 95%, k = 5), with two outliers removed. No publication bias was detected. Subgroup analysis highlighted effects of "sampling method" (p < 0.05), "study quality" (p < 0.05), "developmental status" (p < 0.05), "forms of social media" (p < 0.05), and "type of population" (p < 0.01) on the estimated pooled effect sizes. Although univariate meta-regression showed the effects of "% of Internet users" (p < 0.05) and "male%" (p < 0.05), and multivariate meta-regression showed the combined effect of moderators only on the relationship between problematic SMU and subjective well-being.

Experiences of undergraduate nursing students and new graduate nurses in paid employment models and health-related work influencing the transition to practice: a qualitative systematic review protocol.

This review aims to synthesize qualitative literature exploring the experiences of undergraduate nursing students and newly graduated nurses who are employed for less than 1 year in clinical settings after graduation. It will focus on those who had paid employment and health-related work experience during their undergraduate studies, examining the influence of these experiences on the transition to practice. Nursing professionals undergo a transformative journey, starting from envisioning themselves as nurses, to developing professional identity and competence. However, the initial transition to nursing practice often poses challenges for undergraduates and newly graduated nurses. To ease this transition, gaining additional clinical experience through paid employment or health-related work during undergraduate studies can be beneficial. This review will include qualitative studies on the experiences of undergraduate nursing students and newly graduated nurses in paid employment models and health-related work. No restrictions on the publication date or country will be applied; however, only English-language publications will be included. The JBI methodology for qualitative systematic reviews will be employed. Searches will be conducted in MEDLINE, Embase, Emcare (Ovid); CINAHL Complete (EBSCOhost); and ERIC (ProQuest), along with gray literature in ProQuest Dissertations and Theses and Google Scholar. Study selection, quality assessment, and data extraction will be conducted as per the JBI methodology. Findings will be synthesized using meta-aggregation, and a ConQual Summary of Findings will be created. PROSPERO CRD42024520724.

The Role of Radiomics in the Prediction of Clinically Significant Prostate Cancer in the PI-RADS v2 and v2.1 Era: A Systematic Review.

Early detection of clinically significant prostate cancer (csPCa) has substantially improved with the latest PI-RADS versions. However, there is still an overdiagnosis of indolent lesions (iPCa), and radiomics has emerged as a potential solution. The aim of this systematic review is to evaluate the role of handcrafted and deep radiomics in differentiating lesions with csPCa from those with iPCa and benign lesions on prostate MRI assessed with PI-RADS v2 and/or 2.1. The literature search was conducted in PubMed, Cochrane, and Web of Science databases to select relevant studies. Quality assessment was carried out with Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2), Radiomic Quality Score (RQS), and Checklist for Artificial Intelligence in Medical Imaging (CLAIM) tools. A total of 14 studies were deemed as relevant from 411 publications. The results highlighted a good performance of handcrafted and deep radiomics methods for csPCa detection, but without significant differences compared to radiologists (PI-RADS) in the few studies in which it was assessed. Moreover, heterogeneity and restrictions were found in the studies and quality analysis, which might induce bias. Future studies should tackle these problems to encourage clinical applicability. Prospective studies and comparison with radiologists (PI-RADS) are needed to better understand its potential.
