The optimal approach for retrieving systematic reviews was achieved when searching MEDLINE and Epistemonikos in addition to reference checking: a methodological validation study

BackgroundSystematic reviews (SRs) are used to inform clinical practice guidelines and healthcare decision making by synthesising the results of primary studies. Efficiently retrieving as many relevant SRs as possible is challenging with a minimum number of databases, as there is currently no guidance on how to do this optimally. In a previous study, we determined which individual databases contain the most SRs, and which combination of databases retrieved the most SRs. In this study, we aimed to validate those previous results by using a different, larger, and more recent set of SRs.MethodsWe obtained a set of 100 Overviews of Reviews that included a total of 2276 SRs. SR inclusion was assessed in MEDLINE, Embase, and Epistemonikos. The mean inclusion rates (% of included SRs) and corresponding 95% confidence intervals were calculated for each database individually, as well as for combinations of MEDLINE with each other database and reference checking. Features of SRs not identified by the best database combination were reviewed qualitatively.ResultsInclusion rates of SRs were similar in all three databases (mean inclusion rates in % with 95% confidence intervals: 94.3 [93.9–94.8] for MEDLINE, 94.4 [94.0-94.9] for Embase, and 94.4 [93.9–94.9] for Epistemonikos). Adding reference checking to MEDLINE increased the inclusion rate to 95.5 [95.1–96.0]. The best combination of two databases plus reference checking consisted of MEDLINE and Epistemonikos (98.1 [97.7–98.5]). Among the 44/2276 SRs not identified by this combination, 34 were published in journals from China, four were other journal publications, three were health agency reports, two were dissertations, and one was a preprint. When discounting the journal publications from China, the SR inclusion rate in the recommended combination (MEDLINE, Epistemonikos and reference checking) was even higher than in the previous study (99.6 vs. 99.2%).ConclusionsA combination of databases and reference checking was the best approach to searching for biomedical SRs. MEDLINE and Epistemonikos, complemented by checking the references of the included studies, was the most efficient and produced the highest recall. However, our results point to the presence of geographical bias, because some publications in journals from China were not identified.Study registrationhttps://doi.org/10.17605/OSF.IO/R5EAS (Open Science Framework).

Contextual Factors Influencing Firearm Deaths Occurring Among Children.

Contextual factors that contribute to firearm injuries among children aged 0 to 10 are not well understood. A retrospective review of the National Fatality Review-Case Reporting System was conducted for firearm deaths of children aged 0 to 10 from 2004 to 2020. Descriptive analyses characterized child and parent demographics, incident details, firearm characteristics, and firearm use. Cluster analysis identified key clustering of contextual variables to inform prevention efforts. Within the study timeframe, 1167 child firearm deaths were reported (Mage = 4.9; 63.2% male; 39.4% urban). At the time of the incident, 52.4% of firearms were reported unlocked and 38.5% loaded. Firearm deaths occurred primarily at the child's home (69.0%) or a friend or relative's home (15.9%), with most involving a handgun (80.6%). Children were supervised in 74.6% of incidents, and 38.4% of child supervisors were impaired during the incident. Cluster analysis identified incident contextual factors clustering in distinct groups, including unsupervised firearm play, long gun discharge while cleaning, hunting, or target shooting, supervised discharge within the child's home, murder-suicide events, deaths occurring in the context of intimate partner violence, and community violence firearm deaths. Data highlight the importance of primary prevention through secure firearm storage to prevent child firearm deaths. Efforts focused on identifying and reducing intimate partner violence, addressing community violence (eg, community greening), and implementing policy that limit firearm access (eg, domestic violence restraining orders, background checks), may reduce child firearm deaths.

Employer Credit Checks: Poverty Traps Versus Matching Efficiency

Abstract We develop a framework to understand pre-employment credit screening as a signal from credit markets that alleviates adverse selection in labour markets. In our theory, people differ in both their propensity to default on debt and the profits they create for firms that employ them; in our calibrated economy, highly productive workers have a low default probability. This leads firms to create more jobs for those with good credit, which creates a poverty trap: an unemployed worker with poor credit has a low job finding rate, but cannot improve her credit without a job. This manifests as an endogenous loss in present-discounted wages that is typically taken as exogenous in quantitative models of consumer default. Banning employer credit checks eliminates the poverty trap, but pools job seekers and reduces matching efficiency: average unemployment duration rises by 2 days for high productivity workers and falls by 13 days for low-productivity workers.

Electronic screening and brief interventions promoting healthy diet and physical activity among adult patients in medical settings: A systematic review

Background & AimsElectronic screening and brief interventions (eSBIs) are promising health promoting approaches but their utilization towards nutrition outcomes has been little documented so far. The aim of this systematic review is to examine the nature and findings of eSBIs targeting diet and/or physical activity (PA) among adult patients in healthcare settings since smartphone technologies emerged. MethodsThree systematic searches in PubMed, ScienceDirect and PsycINFO were conducted from January 2010 to May 2023. We include all studies assessing eSBI towards lifestyle habits (dietary habits and/or PA at least), implemented in healthcare settings and targeting adult participants. ResultsOf 1981 articles identified, 15 studies met inclusion criteria. Most of them documented eSBIs implemented in primary care (n=11), targeting PA (n=11) and diet (n=9) alone or combined (n=5). Some eSBIs targeted additional behaviors (e.g. smoking, drinking). Delivery modes included computer (n=8), printed documents (n=8) or phone (n=2) but only four eSBIs were interactive (or partially automated). In addition to personalized feedback, most common behavior change techniques were “information about social and environmental consequences” (n=9), “goal setting” (n=7), and “information about health consequences” (n=7). Most studies assessing behavior change had a control group (8 in 10), and eight studies found positive changes in behavior. ConclusionsAlthough implementing eSBIs towards PA/diet among adult patients in medical settings seems promising for primary, secondary and tertiary prevention, common conceptual framework, intervention and outcomes are severely lacking, and the extent to which they follow existing SBI guidelines remains unclear. Demonstrating their effectiveness requires fixing these issues before conducting prospective assessment studies in medical settings.

Quality of life after screening for atrial fibrillation: a substudy from a randomised screening trial

Abstract Background Screening for atrial fibrillation (AF) is rising, yet trials have failed to show efficacy for stroke prevention from screening and subsequent anticoagulation. Quality of life is an important outcome for patients and physicians, however, it is largely unknown how this outcome is affected by screening for AF. The adverse effects of screening should be considered before implementing systematic screening. Purpose To explore changes in quality of life associated with screening for AF and subsequent anticoagulant treatment upon AF detection. Methods We used quality of life data from 6,004 persons with stroke risk factors randomised to usual care (n=4,503) or screening for AF using implantable loop recorder and anticoagulation for AF episodes lasting ≥6 minutes (n=1,501). The validated EQ-5D-5L tool evaluates health-related quality of life in five domains (mobility, selfcare, usual activities, pain/discomfort and anxiety/depression), rendering a final score in EQ-index (worst=-0.76 best=1.00) combined with an EQ-VAS score (worst=0, best=100). EQ-index and EQ-VAS were analysed with linear mixed models from baseline through year three. The domains were also analysed with logistic regression to report the risk of major problems (defined as a rating of 3, 4, or 5 in the range [1-5], where 1 corresponds to no problem and 5 corresponds to an extreme problem within a given domain) overall and separately. Sensitivity analyses with imputation for missing data were performed. Results Data were available for 5,162 (86.0%) participants at baseline and in year three, and 227 (5.0%) in usual care and 65 (4.3%) in the screened group had died before the last assessment. At baseline, 1,202 of 5,162 (23.3%) participants reported major pain/discomfort problems, and 666 of 5,162 (12.9%) reported major mobility problems (Figure 1). Major selfcare problems were the least frequent problem reported by 83 of 5,162 participants (1.6%). The occurrence of major problems was increased after 3 years in all domains and in both randomisation groups, with a 2% higher occurrence of major pain/discomfort in the control group compared to the screened group. At baseline, the average EQ-index was 0.88 (±0.16) and EQ-VAS 78.4 (±16.2). After three years, the EQ-index decreased by -0.05 (-0.05; -0.04), p<0.0001 in the control group vs. -0.04 (-0.05; -0.02) in the screened group and EQ-VAS with -6.06 (-6.54; -5.57) in the control group vs. -5.18 (-6.52; -3.78) in the screened group, resulting in no statistically significant difference between the groups (p=0.063 and p=0.056) (Figure 2). The screened group was equally likely to report at least one major problem in quality of life after three years (odds ratio 0.93 (0.77;1.13)), but was less likely to report major pain/discomfort (odds ratio 0.84 (0.72;0.98)), compared with the control group. Conclusion Systematic and intensive screening for atrial fibrillation did not improve quality of life compared to usual practice.

Atrial fibrillation screening to prevent stroke in persons with low-normal thyrotropin

Abstract Background Screening for atrial fibrillation (AF) has been proposed as a method to prevent strokes in high-risk individuals. Recent trials were unable to prove efficacy for stroke prevention but suggested that a more refined approach may be beneficial. Low-normal thyroid-stimulating hormone (TSH) is a marker for AF and stroke risk and may be used to select individuals for AF screening. Purpose To explore TSH as a tool to select individuals for AF screening to prevent stroke. Methods Post hoc analysis of a clinical trial enrolling 6004 participants with stroke risk factors but no known AF randomized 1:3 to implantable loop recorder (ILR) screening for AF and initiation of oral anticoagulation (OAC) upon AF detection versus usual care (control group). The primary outcome was stroke or systemic embolism (SE). Secondary outcomes included the combination of stroke, SE, or cardiovascular (CV) death, all-cause death, AF diagnosis, and OAC initiation. All outcomes were adjudicated. Results Baseline TSH was measured in 6003 participants (99.98%); 1500 randomized to ILR vs 4503 to control. The mean age was 75±4 years, 2836 (47%) were women. The tertiles of TSH were at ≤1.2, 1.2-1.9, and >1.9 mIU/L. Participants in the first tertile had slightly higher levels of the thyroid hormones (T3, T4, and free T4), were slightly younger, had more smoking pack-years, and higher pulse rate compared to other tertiles. The median follow-up duration was 5.4 (4.9-5.8) years, and no participants were lost to follow-up. AF was diagnosed in 476 (31.7%) participants in the ILR group vs 550 (12.2%) in the control group and this difference was similar across tertiles (p-interaction=0.44). Similar patters were observed for OAC initiation. In the first TSH tertile, participants in the ILR group were significantly less likely to experience the primary outcome (hazard ratio 0.52 [0.30–0.90]; p=0.019) or the combination of stroke, SE, or CV death (hazard ratio 0.54 [0.35–0.84]; p=0.006, respectively) compared to control, while there was no effect in participants with higher TSH (p-interaction 0.029 and 0.014, respectively) and there was no effect on all-cause death in any tertile. When TSH was modelled as a continuous variable, the effect of ILR screening gradually increased with decreasing TSH, with the upper bound of the confidence interval reaching HR<1 at TSH<1.2-1.5 mIU/L. Sensitivity analyses excluding participants with baseline TSH outside reference range (0.3-4.0 mIU/L) and/or treated with thyroid hormone replacement or antithyroid agents yielded similar results. Conclusion In persons with stroke risk factors and TSH <1.2-1.5 mIU/L, ILR screening for AF and anticoagulation upon detection led to significantly decreased stroke risk. There was no effect in persons with higher TSH, though the yield of screening was similar across levels. This suggests that low-normal TSH may indicate benefit from AF screening while higher levels may lead to overdiagnosis.TableFigure

Coronary CTA and CT-FFR in trans-catheter aortic valve implantation candidates: a systematic review and meta-analysis

Abstract Objectives To perform a systematic review and meta-analysis on diagnostic accuracy and other outcomes of coronary computed tomography angiography (CCTA) and CT-derived fractional flow reserve (CT-FFR) in candidates for trans-catheter aortic valve implantation (TAVI). Background Screening for obstructive coronary artery disease (CAD) with CCTA during TAVI work-up could prevent unnecessary invasive coronary angiography (ICA). This becomes increasingly relevant as the TAVI-population grows. CT-FFR improves CCTA accuracy in chest pain patients, but its reliability is unknown in the TAVI-population. Methods Pubmed, Embase and Web of Science were searched for studies regarding CCTA and/or CT-FFR in TAVI-candidates. Primary endpoint was correct identification and rule-out of obstructive CAD. Results were pooled in a meta-analysis. Results Twenty-four of the 29 included articles were part of the meta-analysis, reporting results for CCTA and CT-FFR in 3.494 and 797 patients respectively. Reference standard was anatomical severity of CAD in most studies. At patient-level, pooled CCTA sensitivity was 94.3% and specificity 74.8%. CT-FFR sensitivity was 91.5% and specificity 60.3% with strong variation between studies. CCTA correctly ruled out CAD in 52% of all patients, but 42% of positive CCTAs were false positives. CT-FFR correctly ruled out CAD in 47% of all patients included in this meta-analysis, but showed better accuracy than CCTA in studies that compared both. In these studies, sensitivity of CCTA versus CT-FFR was 70.7% versus 79.0% and specificity was 64.4% versus 92.9%. Conclusions Negative CCTA effectively rules-out CAD in the TAVI-population. Adding CCTA to TAVI work-up could lead to significant reduction in pre-TAVI ICA procedures, but the proportion of false-positives remains high. In studies performing a direct comparison, CT-FFR performed better than CCTA. This is not reflected in the CT-FFR meta-analysis. Therefore, diagnostic accuracy of CT-FFR and added value over CCTA in the TAVI-population remains unclear. Further research regarding validation and reliability is warranted.Meta-analysis of CCTA and CT-FFR

The role of co-infections on cervical intraepithelial neoplasia prevalence in western Kenya.

Background Screening for co-infections with HIV, HSV-2 and Chlamydia trachomatis (CT ) among high-risk human papilloma virus (hr-HPV) positive women remains essential in alleviating high morbidity of cervical cancer (CC). The aim of this study was to determine the prevalence of cervical intraepithelial neoplasia (CIN) among women referred for CC screening at a referral hospital in Kisumu County, Kenya; and to establish the role of co-infection on CIN. Method In a cross-sectional study, we collected HPV, HIV, HSV-2 and CT data, cervical cytology results, and demographic information from 517 referrals. Blood samples were obtained for HIV and HSV-2 tests; urine for CT test and cervical swabs for hr-HPV test. Results The overall prevalence of CIN was 18.4% (95/517) with CIN1 observed in 56(29.6%), CIN2 in 27(`14.3%), CIN3 + in 12(6.3%) and normal biopsy in 94(49.7%) of the patients out of which high grade CIN2 and above (CIN2+) was 7.54% (39/517) equivalent to 32.5 per 100,000 women per year. HPV/HIV co-infection (infected vs. uninfected: OR 2.79; 95% CI 1.56-5.10, p < 0.001); HPV/HSV-2 co-infection (infected vs. uninfected: OR 2.41, 95% CI: 1.12-5.46, p < 0.024); HPV/CT co-infection (infected vs. uninfected: OR 3.83; 95% CI 1.84-8.51, p < 0.001) were found to be significantly associated with CIN. Conclusion Overall prevalence of CIN was high in the region although high-grade CIN2 + remained relatively lower as reported earlier. Age factor, widowhood and co-infections with HIV, HSV-2 or Chlamydia trachomatis were associated with increased risk of testing positive for CIN.

Maternal Nutrition and Human Milk Nutrients

Abstract Purpose: To explore the influence of maternal nutrition factors, including body mass index, nutritional supplementation, and dietary intake during the breastfeeding period, on macro and micronutrient composition in human milk. Study Design and Methods: We conducted a scoping review using the PRISMA-ScR checklist, initially identifying 5,984 original studies published in the English language from PubMed, Scopus, and Web of Science that presented findings on the association of maternal nutritional factors on human milk nutrient composition. After screening the title and abstract, we selected 69 studies for full review, including 3 studies found through checking reference lists. After full review, we included 23 studies in this scoping review. Results: Most studies found maternal body mass index and supplement consumption affected human milk macro and micronutrient composition, whereas inconsistent results were found on the relationship between maternal diet and human milk nutrients. Methodologies varied substantially across studies, especially for milk sample collection methods and maternal nutrition assessments. Clinical implications: Maternal nutrition factors may affect levels of human milk nutrients, requiring maternal nutrition monitoring during breastfeeding. However, given the considerable variability in the results between studies and methodological approaches, further studies should use standardized and validated procedures to strengthen the findings on this topic.

A-359 Clinical Performance Evaluation of the Polymerase Chain Reaction (PCR)-Based cobas CT/NG/MG Test for Use on the cobas liat System in a Clinical Laboratory Setting and Point-of-Care (POC) Location

Abstract Background Screening for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Mycoplasma genitalium (MG) can be achieved rapidly (in approximately 20 minutes) with the cobas® CT/NG/MG test (assay not cleared by US FDA. Submission currently under review and subject to change per health authority feedback). This automated, qualitative, real-time PCR-based nucleic acid amplification test (NAAT) is for use on the cobas® liat® system. This study evaluated the test’s clinical performance using urogenital samples from symptomatic and asymptomatic patients. Methods This non-interventional, non-observational study used prospective clinician-collected and self-collected specimens (urine, and vaginal swabs, all in cobas® PCR Media) from symptomatic/asymptomatic patients ≥14 years old from 13 POC sites across the US. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of cobas liat CT/NG/MG were calculated with respect to patient infected status (PIS), as determined using results from three FDA-approved NAATs and one laboratory-developed test. Due to insufficient positive NG samples during the trial period, further testing used archived samples. Results The median (range) age of the study population (N=4,800) was 35.0 (15.0-81.0) years; 40.4% (n=1,941) were symptomatic and 51.9% (n=2,489) were assigned female at birth. The cobas CT/NG/MG nucleic acid test demonstrated good clinical performance (Table 1). Across all specimen types, specificity was &amp;gt;97% for each analyte. Sensitivity was ≥95%, except in female urine (CT 87.0%, NG 93.1%, MG 78.9%). Regardless of specimen type, PPV and NPV were ≥95% for CT and NG; PPV for MG was highest in male urine (92.7%) and NPV was &amp;gt;97.5% across analytes. Conclusions In a clinical setting, the cobas CT/NG/MG nucleic acid test showed good clinical performance for the detection of CT, NG, and MG in urogenital samples, in addition to providing a short turn-around time and centralized testing lab quality at the POC for both self- and clinician-collected samples.

Comprehensive Analysis Of Background Screening Impact On Employee Experience And Organizational Outcomes

This comprehensive study examines the multifaceted impact of background checks on employee experience and organizational outcomes, with a particular focus on the implementation of a nationwide, standardized employment screening system. The research is guided by six interconnected themes: trust, transparency, fairness, diversity and inclusion, engagement, and retention. In the contemporary business landscape, background checks have transcended their traditional role as a mere formality, evolving into critical assets for enhancing employee satisfaction, organizational trust, and retention rates. This review synthesizes a wide array of studies to analyze the complex interplay between background screening practices and employer-employee relationships. It establishes robust evidence for how fair, transparent, and reasonable background checks can significantly enhance organizational commitment and employee loyalty. The results underscore the critical importance of awareness and transparency in the background check process, highlighting how these factors foster trust and perceptions of fairness, ultimately leading to positive employee attitudes and improved organizational outcomes. The study also delves into the potential adverse effects of excessive or biased background checks on workforce diversity, with a particular emphasis on historically marginalized groups and individuals with criminal records. It proposes that employers who embrace equality in the workplace and ensure that their background check processes are free from unlawful discrimination can cultivate and maintain a diverse, inclusive, and highperforming workforce. The implications for practice and research are far-reaching. To optimize employee experience and key outcomes such as organizational commitment, job satisfaction, and reduced turnover intention, employers must prioritize fairness, transparency, and inclusiveness in their background check processes. The study identifies critical areas for further research, including sector-specific effects of background screening practices and the impact of emerging technologies and data privacy concerns on background check processes. By reconceptualizing background checks as a strategic tool for building trust and enhancing employee commitment, rather than a mere compliance exercise, organizations can achieve superior outcomes across multiple dimensions of performance. This research provides a comprehensive framework for understanding and implementing effective background screening practices that balance organizational risk management with positive employee experiences.

Cost-Effectiveness of Serum Pepsinogen as a Gastric Cancer Targeted Screening Strategy in the United States

Background and AimsCurrent gastric cancer (GC) screening modalities are invasive and expensive. Noninvasive screening for GC precursors with serum pepsinogen (PG) may improve early detection and prevention. Test characteristics of PG based on US prospective data was recently reported and used to study the cost-effectiveness of PG screening versus no screening in the US. MethodsA patient-level state transition microsimulation of gastric adenocarcinoma analyzed noninvasive screening versus no screening in a hypothetical cohort of average risk US individuals. Primary outcomes included life expectancy, quality-adjusted life years (QALYs), total costs, and incremental cost-effectiveness ratios (ICERs). Secondary outcomes included total GC incidence and mortality. Base-case PG sensitivity and specificity were 34.1% and 94.7%, respectively, with a wide range of PG performance characteristics also examined. ResultsOne-time serum PG screening at age 40 was cost-effective compared to no screening with an ICER of $4,913.29 per QALY. PG screening resulted in 10.9% relative reduction in lifetime GC incidence and 10.8% relative decrease in cumulative GC mortality. Localized stage at diagnosis increased from 30.5% to 33.6% and metastatic stage decreased from 40.8% to 37.4%. Sensitivity analysis showed PG screening was most sensitive to endoscopy costs, chronic atrophic gastritis quality of life, and PG prevalence. PG screening remained cost-effective across a wide range of test values. ConclusionPG screening is a cost-effective strategy to improve GC mortality, however, mortality benefit will depend on the test characteristics of the biomarker. Future blood-based screening tests that have better performance characteristics could further improve GC prevention.

ANTICIPATING BIOSECURITY HAZARDS: DISTRIBUTION AND RECOGNITION OF BIOLOGICAL THREATS

Understanding the potential biological weapons that can be created, the technologies involved, and the entities capable of producing them is crucial for biosecurity. Equally important is comprehending the various targets a biological weapon might be aimed at, the deployment methods, and available detection strategies to counteract illegal biological threats. This chapter delves into these aspects, starting with methods of deployment. The Center for Disease Control and Prevention (CDC) categorizes disease transmission into direct and indirect modes. Direct transmission involves contact with an infected person or environmental reservoir, including droplet spread, proven highly effective in densely populated areas. Indirect transmission occurs through contaminated objects or vectors. Vehicle-based transmission involves contaminating inanimate objects like food, water, and biological products. Vector-based transmission involves organisms carrying and transmitting pathogens. Airborne transmission, receiving significant attention for its potential in biological attacks, involves pathogens suspended in the air, posing significant risks, especially in crowded areas. Biological weapons could target humans, agriculture, technology, and the environment. Attacks on humans, often the focus of biosecurity efforts, pose catastrophic outcomes. State-sponsored programs often focus on human pathogens like Bacillus anthracis and Yersinia pestis. Agroterrorism, targeting agriculture and livestock, can lead to economic losses and social instability. Attacks on technology, utilizing synthetic biology, have shown the potential to manipulate DNA to store and deploy malicious code, highlighting vulnerabilities in sequencing systems. While attacks on the environment remain theoretical, advancements in gene drives raise concerns about manipulating ecosystems. Effective biosecurity involves pre- and post-deployment screening techniques. Pre-deployment screening, particularly gene synthesis, focuses on preventing the acquisition of DNA fragments for weapon production. Current measures involve background checks and screening against pathogen lists, yet gaps exist, including inadequate international policies and the potential to hide malicious sequences within longer ones. Post-deployment detection relies on traditional molecular diagnostic methods, but synthetic pathogens may evade detection, necessitating ongoing advancements in detection techniques. Real-time sensors and biosensors offer promising avenues for quick and accurate pathogen recognition, although challenges remain in detecting novel pathogens against a natural background. In conclusion, understanding the range of biological weapons, their potential targets, deployment methods, and detection strategies is essential for effective biosecurity. Continued research and advancements in detection technologies are crucial to staying ahead of evolving biological threats, ensuring a safer and more secure future.

Understanding lived experiences and perceptions of perinatal depression in Nigeria: a qualitative evidence synthesis

Background Perinatal depression is a common mental health disorder which spans during and after pregnancy. Unfortunately, there is poor healthcare-seeking behaviour for this treatable condition. Additionally, maternal healthcare workers sometimes overlook the signs and symptoms, failing to diagnose it adequately. This review aims to provide a framework for understanding the in-depth perceptions and implementation gaps surrounding perinatal depression in Nigeria. Methods This study employed a rigorous qualitative evidence synthesis methodology to gather and analyse both published and unpublished qualitative research on the lived experiences and perceptions of perinatal depression in Nigeria. The research was conducted by searching multiple electronic databases, citation chaining, and checking reference lists. The studies were then screened by title, abstract, and full text, and the quality of the included studies was evaluated using the Critical Appraisal Skills Programme (CASP) checklist for appraising a qualitative study. The data extracted from these studies were then synthesized using the ‘best-fit’ framework method, which combines deductive and inductive approaches to analysis. Results 10 eligible papers were identified. Data were organised into themes eight themes mapped to an already existing framework: Recognitions of perinatal mental distress, labelling of mental distress, symptom patterns, social norms, roles and expectations, supernatural factors, physical/bodily issues, coping strategies, help-seeking from professionals/medical institutions. No study was excluded as a result of methodological limitations. Conclusions The review highlights the significance of integrating mental health services into routine perinatal care and the need for comprehensive interventions that consider sociocultural factors. The findings emphasize the importance of increasing awareness and education among women and healthcare providers to improve early detection and intervention. Healthcare professionals play a crucial role in identifying and managing perinatal depression; therefore, it is essential to provide them with comprehensive and regular training.

Efficiency of a technology-assisted nutritional screening system: A retrospective analysis of 11,722 admissions in a tertiary hospital

Background and AimNutritional screening is essential for addressing malnutrition and its consequences. However, routine implementation in large hospitals faces several challenges. To overcome these obstacles, the Clinical Nutrition Service of a tertiary hospital developed a technology-assisted nutritional screening system. This study evaluates the system's efficiency in detecting and assessing patients at nutritional risk upon hospital admission. It also examines the association between nutritional risk, clinical outcomes, and sociodemographic characteristics. MethodsThis retrospective, analytical, observational study examined 11,722 hospital admissions of adult patients in 2019, each with a minimum hospital stay of 48 hours in a tertiary hospital. Rates and timing for the detection, referral, and assessment of patients at nutritional risk were calculated. Participants were divided into low (Malnutrition Screening Tool [MST] < 2 points) and moderate/high (MST ≥ 2) nutritional risk groups to evaluate the relationship between nutritional risk and clinical and demographic variables. ResultsWe found that 91% of patients underwent nutritional screening within the first hours of admission, with a median time of 9 hours from admission to screening (interquartile range [IQR] 3-19). The prevalence of nutritional risk (MST ≥ 2) was 21%. All patients identified as being at nutritional risk were immediately referred for a nutritional assessment once identified, with a median referral time of 0 hours (IQR 0-0). This assessment was carried out by a nutritionist for 98% of these patients, with a median time of 19 hours from referral to assessment (IQR 6-24). Compared to the low-risk group, patients with nutritional risk were older, had higher rates of mortality and admission to the intensive care unit (ICU), longer hospital stays, and a higher proportion of men and cancer diagnoses (p=0.00 for all comparisons). After adjusting for age and sex, nutritional risk was significantly associated with a higher probability of ICU admission (Odds Ratio [OR] 1.13; 95% CI 1.02-1.24) and in-hospital mortality (OR 2.32; 95% CI 1.97-2.73). ConclusionThe integration of technology into nutritional screening was highly efficient for early detection and assessment of at-risk patients upon hospital admission. Features of this system could guide other hospitals. The association found between nutritional risk and clinical outcomes emphasizes the importance of prompt and appropriate nutritional interventions.

Poor adherence to proper Barrett’s esophagus screening and surveillance guidelines in patients with newly diagnosed esophageal adenocarcinoma

Background Screening for Barrett’s esophagus (BE) remains controversial, even for high-risk populations. Our study aimed to evaluate the proportion of patients diagnosed with esophageal adenocarcinoma (EAC) who were not screened for BE or did not receive recommended BE surveillance screening. We then evaluated the relationship between cancer staging and screening/surveillance opportunities. Methods This single-center retrospective study included 187 patients from January 2016 to January 2022 with newly diagnosed EAC. Data extracted from patient charts included BE risk factors, and BE, endoscopic, and histologic history. Results A total of 187 patients had a new diagnosis of EAC. Among this group, 44% had appropriate BE surveillance adherence, and 47% of patients met the criteria for BE screening but had not been screened prior to EAC diagnosis. Adherence to BE surveillance was associated with earlier stages of cancer on biopsy. No significant difference in cancer staging was found in those with missed BE screening opportunities. Discussion Patients with a diagnosis of BE who adhered to surveillance guidelines had earlier stage EAC at diagnosis, which emphasizes the importance of surveillance. Most of those with an initial diagnosis of EAC had not received any BE screening.

Demographic differences in perceived effectiveness for policies to prevent school shootings: results from a representative survey in New Jersey

ObjectiveTo determine what firearm policies New Jersey residents believe will prevent school shootings and the extent to which this varies by sex, firearm ownership status, and political affiliation.MethodsA representative sample of New Jersey residents (N = 1,018) was collected via the Eagleton Center on Public Interest Polling (ECPIP). Data were weighted to reflect the state's population. Participants were asked to rate how helpful they perceived different firearm-related policies to be for preventing school shootings.ResultsFindings indicate that participants perceived universal and expanded background checks, increased mental health funding, and requiring a license for firearm purchases as most effective for preventing school shootings. Arming school personnel, prayer in schools, decreasing the number of entrances at schools, and secure storage requirements were viewed as less effective. Firearm ownership, sex, and political affiliation significantly influenced perceptions of the effectiveness of these policies.ConclusionThe study examined the perceived effectiveness of policies to prevent school shootings. The study highlights disparities and commonalities in policy support among different groups, emphasizing the importance of collective efforts to address gun violence in schools.

Canada's Medical Assistance in Dying System can Enable Healthcare Serial Killing.

The Canadian approach to assisted dying, Medical Assistance in Dying (MAiD), as of early 2024, is assessed for its ability to protect patients from criminal healthcare serial killing (HSK) to evaluate the strength of its safeguards. MAiD occurs through euthanasia or self-administered assisted suicide (EAS) and is legal or considered in many countries and jurisdictions. Clinicians involved in HSK typically target patients with the same clinical features as MAiD-eligible patients. They may draw on similar rationales, e.g., to end perceived patient suffering and provide pleasure for the clinician. HSK can remain undetected or unconfirmed for considerable periods owing to a lack of staff background checks, poor surveillance and oversight, and a failure by authorities to act on concerns from colleagues, patients, or witnesses. The Canadian MAiD system, effectively euthanasia-based, has similar features with added opportunities for killing afforded by clinicians' exemption from criminal culpability for homicide and assisted suicide offences amid broad patient eligibility criteria. An assessment of the Canadian model offers insights for enhancing safeguards and detecting abuses in there and other jurisdictions with or considering legal EAS. Short of an unlikely recriminalization of EAS, better clinical safeguarding measures, standards, vetting and training of those involved in MAiD, and a radical restructuring of its oversight and delivery can help mitigate the possibility of abuses in a system mandated to accommodate homicidal clinicians.

Universal Background Checks, Permit Requirements, and Firearm Homicide Rates

A loophole in US gun policy is that people can purchase guns from private sellers without going through any background check. Some states have addressed this loophole by requiring universal background checks for all gun sales, either at the point of sale or through a permit system; however, most studies on the effectiveness of universal background checks have not analyzed these 2 policy mechanisms separately. To assess the association of point-of-sale background check law and gun permit law, separately, with firearm homicide rates from 1976 through 2022 using the same methods and model specification. This cross-sectional study used a difference-in-differences, fixed-effects regression model to evaluate firearm laws and firearm homicide rates in 48 states from 1976 through 2022. Data were obtained for 48 states except New Hampshire and Vermont and were analyzed in January 2024. Implementation of either the law requiring a universal background check at point of sale for all firearms without a permit or the laws combining universal background checks and a state permit requirement for all gun purchasers. Annual, state-specific rates of firearm homicide per 100 000 people. From 1976 through 2022, 12 states adopted the universal background check laws without permitting requirements and 7 states implemented gun permit laws covering all firearms. The mean (SD) firearm homicide rate was 4.3 (0.1) per 100 000 people. Universal background checks for all firearms alone (without a state permitting system) were not associated with overall homicide rates (percentage change, 1.3%; 95% CI, -6.9% to 10.4%) or firearm homicide rates (percentage change, 3.7%; 95% CI, -5.3% to 13.6%). A law requiring a permit for the purchase of all firearms was associated with significantly lower overall homicide rates (percentage change, -15.4%; 95% CI, -28.5% to -0.01%) and firearm homicide rates (percentage change, -18.3%; 95% CI, -32.0% to -1.9%). This cross-sectional study found that universal background checks alone were not associated with firearm homicide rates, but a permit requirement for the purchase and possession of firearms was associated with substantially reduced rates of firearm homicide. The findings suggest that combining universal background checks and permit-to-purchase requirements is an effective strategy for firearm-related fatality reduction.
