The development of microbial products for cancer treatment has been in the spotlight in recent years. In order to accelerate the lengthy and expensive drug development process, in silico screening tools are systematically employed, especially during the initial discovery phase. Moreover, considering the steadily increasing number of molecules approved by authorities for commercial use, there is a demand for faster methods to repurpose such drugs. Here we present a review on virtual screening web tools, such as publicly available databases of molecular targets and libraries of ligands, with the aim to facilitate the discovery of potential anticancer drugs based on microbial products. We provide an entry-level step-by-step description of the workflow for virtual screening of microbial metabolites with known protein targets, as well as two practical examples using freely available web tools. The first case presents a virtual screening study of drugs developed from microbial products using Caver Web, a web tool that performs docking along a tunnel. The second case comprises a comparative analysis between a wild type isocitrate dehydrogenase 1 and a mutant that results in cancer, using the recently developed web tool PredictSNPOnco. In summary, this review provides the basic and essential background information necessary for virtual screening experiments, which may accelerate the discovery of novel anticancer drugs.

PurposeThe aim of our study was to investigate the value of baseline and preoperative neutrophil-to-lymphocyte ratio (NLR) in predicting the pathological response and disease-free survival (DFS) of neoadjuvant chemotherapy alone or combined with programmed cell death-1 (PD-1) checkpoint inhibitors in patients with resectable non‒small cell lung cancer (NSCLC).Materials and MethodsResectable NSCLC patients who underwent neoadjuvant chemotherapy alone or combined with PD-1 checkpoint inhibitors between January 2018 and January 2020 were included. Peripheral venous blood samples of the patients were collected within 3 days prior to the first neoadjuvant treatment and within 3 days prior to surgery.ResultsA total of 79 patients in neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors group and 89 patients in neoadjuvant chemotherapy alone group were included. Thirty-five point four percent of the patients achieved pathological complete response (pCR) in neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors group, whereas only 9.0% reached pCR in the group of neoadjuvant chemotherapy. High NLR level were correlated with poor pathological response and DFS in neoadjuvant chemotherapy or combined with PD-1 checkpoint inhibitors group. Multivariate analysis revealed that baseline NLR could independently predict pathological response and DFS in the neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors group. ConclusionHigh NLR level were correlated with poor pathological response and shorter DFS in patients with NSCLC undergoing neoadjuvant chemotherapy or combined with PD-1 checkpoint inhibitors. Meanwhile, baseline NLR could independently predict response to pathological response and DFS, revealing its potential as a screening tool in NSCLC patients who received neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors.

Background The loco-check has been widely used to raise awareness of locomotive syndrome (LS) not only in the general population but also among medical practitioners. However, a screening tool of the loco-check for LS-1, LS-2, and LS-3 has not yet been established. The present study developed a screening tool for use with the loco-check to detect LS-1, LS-2, and LS-3. Methods A cross-sectional study of 1659 community-dwelling older adults (730 males, 929 females) with a mean age of 73.8 ± 6.0 years old (range, 65–96 years old) was conducted, based on the Standards for Reporting Diagnostic Accuracy (STARD). All subjects underwent the loco-check as an index test and the 25-question Geriatric Locomotive Function Scale (GLFS-25) as a reference standard at the same time. Subjects with a GLFS-25 total score of ≤6 points, 7–15 points, 16–23 points, and ≥24 points were diagnosed with non-LS, LS-1, LS-2, and LS-3, respectively. A conventional receiver-operating characteristic curve analysis was used to confirm the optimal cut-off values of the loco-check score and their sensitivity and specificity to identify LS-1, LS-2, and LS-3, with a preference for a slightly higher sensitivity as the tool is intended primarily for screening purposes. Results The optimal cut-off values of the loco-check score to discriminate LS-1, LS-2, and LS-3 as a screening tool were 1 point (sensitivity 85.4% and specificity 64.9%), 2 points (sensitivity 88.8% and specificity 75.1%), and 3 points (sensitivity 87.6% and specificity 84.6%), respectively. Conclusions Our findings may help both the general population and medical practitioners become roughly aware of and estimate the severity of LS, which will contribute to its use in community health activities and the dissemination of the concept of LS.

Youth involved in the juvenile justice system are at elevated risk for suicide and co-occurring mental health symptoms. This study aims to examine the suicide risk and treatment needs of court-involved, non-incarcerated (CINI) youth, and to understand the acceptability and effectiveness of implementing a mental health screening procedure at time of first court contact. By embedding a forensic mental health screening tool into the intake process of a family court diversionary program, a total of 891 youth (aged 12-18) were assessed using the Massachusetts Youth Screening Instrument-2 (MAYSI-2). Analysis of screening responses revealed 12.5% of youth indicated risk for suicide with risk levels differentiated by youth sex, race and ethnicity. Suicide ideation was also significantly associated with flagging, an indication of clinical risk, on all other scales of the MAYSI-2, as well as subsequent referrals to treatment. Screening for suicide at first point of court contact within an existing diversionary program may serve as a critical and effective point of intervention for youth in need.

Purpose People with type 1 diabetes have an increased risk of disordered eating (DE) and eating disorders (ED). Screening is recommended however little is known about patients’ perspectives on screening questionnaires. This paper reports qualitative analyses of patients’ perspectives on the questionnaire Diabetes Eating Problem Survey Revised (DEPS-R), including acceptability, attitudes, and cognitive understanding. Research design and methods 15 adolescents with type 1 diabetes between 11 and 18 years, were interviewed. A semi-structured format and a qualitative Interpretive Descriptive (ID) methodology was chosen. Results The analyses identified four themes: (1) The Questionnaire, (2) Reframing Diabetes Visits, (3) This is (not) for me, and (4) Out in the Open. The DEPS-R was completed with-in 5–10 min. with no technical difficulties. The questionnaire altered the diabetes visit for some, creating a new dialog, and time for self-reflection. Adolescents appreciated the direct approach in the questionnaire, and showed willingness to complete the questionnaire, when presented to them by a health care professional (HCP). One item in the DEPS-R proved difficult to understand for some participants. Conclusion The study highlights DEPS-R as a clinically relevant screening questionnaire. Completing DEPS-R prior to a consultation opens the door to a consultation that invites the adolescent to address matters of eating behavior. Our findings suggest that systematic screening of DE/ED using the DEPS-R is both accepted and welcomed by adolescents with type 1 diabetes. Future research should focus on a potential update of selected items in DEPS-R. Level of evidence V – qualitative study.

Background Hereditary transthyretin amyloidosis (ATTRv) is a rare, debilitating and fatal disease, mostly characterized by progressive axonal peripheral neuropathy. Diagnosis is still challenging and diagnostic delay in non-endemic area is about 3–4 years. The aim of this study was to arrange a clinical and electrophysiological score to select patients with axonal neuropathy that deserve screening for TTR mutation. Methods Thirty-five ATTRv patients and 55 patients with chronic idiopathic axonal polyneuropathy (CIAP) were retrospectively analyzed. Clinical and electrophysiological findings at first evaluation were collected. Based on significant results between the two groups, a compound (clinical and electrophysiological) score was arranged, and ROC analysis was performed to identify the ideal cut-off able to discriminate between the two groups. Results ATTRv patients presented a later age at onset, more frequent muscle weakness and carpal tunnel syndrome history. On the other hand, electrophysiological analysis showed that ATTRv patients had lower CMAP and SAP amplitude in all examined nerves. We arranged a compound score constituted by 7 total items, ranging from 0 to 12. ROC analysis showed an Area Under the Curve = 0.8655 and we set the cut-off ≥ 5 points to discriminate ATTRv patients with a sensitivity of 96.6% and a specificity of 63.6%. Conclusion Our study demonstrated that our compound score with cut-off ≥ 5 allows to discriminate ATTRv patients among subject affected by axonal polyneuropathy with a sensitivity > 95%. Thus, our compound score is a quick, easy and effective screening tool.

BACKGROUND Selection of residents is a challenging process. The use of personality inventories to evaluate applicants has been validated in professions outside of healthcare. It has been shown that job applicants could not game the personality evaluation. OBJECTIVE The purpose of this study was to determine if orthopaedic surgery residents could game the personality assessment to make themselves seem like a better fit for orthopaedic surgery residencies. METHODS In 2017, 20 orthopaedic surgery residents at a single program were administered a validated personality assessment twice. On one occasion, they were instructed to answer honestly. On the other, they were instructed to shade their answers in a way that they would want a program to see them. Assessments were scored on 9 scales to determine how many were modified to a more desirable result based on previously determined results for desirability of orthopaedic residents. RESULTS Nineteen of 20 subjects had at least one of the nine scales that was “undesirable” when taking the test honestly. The average was 2.1. Forty-two out of a possible 180 results were “undesirable” when the test was taken honestly. 41 of the 42 became desirable when the subjects were instructed to shade their answers. CONCLUSIONS Orthopaedic surgery residents were able to modify their answers to a personality assessment enough to hide most “red flag” findings when they were instructed to shade questions toward answers they thought would be desirable by a program. This limits the utility of personality assessments as screening tools for residency applications.

This cross-sectional study measured the sensitivity and specificity of muscle ultrasound (MUS) in the assessment of patients with suspected limb-girdle muscular dystrophy (LGMD). Sixty patients with suspected LGMD from the Neuromuscular Unit, Myology Clinic, Ain Shams University Hospital, Cairo, Egypt, and a series of healthy subjects were included. The patients underwent real-time B-mode ultrasonography performed using a General Electric ultrasound machine (GE Logiq P7) and a General Electric 7.5 MHz linear array ultrasound probe (USA). All images were obtained and scored by a single examiner, and muscle echo intensity was visually graded semiquantitatively using Heckmatt's scale. The examiner was blinded to the clinical evaluations and patients' investigations. Statistical analysis using receiver operating characteristic (ROC) curve analysis revealed that the total upper-limb (UL) Heckmatt's US score at a cutoff point1 predicted patients with dystrophy, with good (88%) accuracy and with sensitivity and specificity of 100% and 75%, respectively (p 0.01). Moreover, the total lower-limbs (LL) Heckmatt's US score at a cutoff point1 predicted patients with dystrophy, with excellent (91%) accuracy and with sensitivity and specificity of 100% and 75%, respectively (p 0.01). Finally, the total Heckmatt's US score at a cutoff point2 predicted patients with dystrophy, with good (89%) accuracy and with sensitivity and specificity of 100% and 75%, respectively (p 0.01). Thus, MUS can be considered a valid screening tool in the assessment of patients with suspected LGMD.

Background and Purpose: Two-dimensional high-resolution multicontrast magnetic resonance imaging (2D-MC MRI) is currently the most reliable and reproducible noninvasive carotid vessel wall imaging technique. However, the long scan time required for 2D-MC MRI restricts its practical clinical application. Alternatively, 3-dimensional motion-sensitized driven-equilibrium prepared rapid gradient echo (3D-MERGE) vessel wall MRI can provide high isotropic resolution with extensive coverage in two minutes. In this study, we sought to prove that 3D-MERGE alone can serve as a screening tool to identify advanced carotid lesions. Methods: Two hundred twenty-seven subjects suspected of recent ischemic stroke or transient ischemic attack were imaged using 2D-MC MRI with an imaging time of 30 minutes, then with 3D-MERGE with an imaging time of 2 minutes, on 3T-MRI scanners. Two experienced reviewers interpreted plaque components using 2D-MC MRI as the reference standard and categorized plaques using a modified American Heart Association lesion classification for MRI. Plaques of American Heart Association type IV and above were classified as advanced. Arteries of American Heart Association types I to II and III were categorized as normal or with early lesions, respectively. One radiologist independently reviewed only 3D-MERGE and labeled the plaques as advanced if they had a wall thickness of >2 mm with high or low signal intensity compared with the adjacent sternocleidomastoid muscle. Sensitivity, specificity, and accuracy for 3D-MERGE were calculated. Results: Four hundred forty-nine arteries from 227 participants (mean age 61.2 years old, 64% male) were included in the analysis. Sensitivity, specificity, and accuracy for identification of advanced lesions on 3D-MERGE were 95.0% (95% CI, 91.8–97.2), 86.9% (95% CI, 81.4–92.0), 93.8% (95% CI, 91.1–95.8), respectively. Conclusions: 3D-MERGE can accurately identify advanced carotid atherosclerotic plaques in patients suspected of stroke or transient ischemic attack. It has a more extensive coverage and higher sensitivity and specificity for advanced plaque detection with a much shorter acquisition time than 2D-MC MRI.

OBJECTIVE The aim of this study was to compare the efficacy of a modified Dionne's Egress Test (Egress) as a predictor of falls with the Morse Fall Scale (MFS) in adult medical and surgical patients in an acute care setting. BACKGROUND Nurses must identify fall risk while balancing fall prevention and early mobility in their care delivery. Fall risk screening tools alone are not enough to assist nurses in predicting patients at risk of falling. METHODS A retrospective observational study design was used to compare the Egress as a predictor of falls to the MFS. The sample included data abstracted from 197 electronic health records and internal falls data. RESULTS The Egress and the MFS are moderately and negatively correlated; however, only Egress was a significant predictor of falls. Passing the Egress, not being on benzodiazepines, and having a longer length of stay (LOS) results were associated with being less likely to fall. CONCLUSION Egress is a better predictor of falls than MFS when benzodiazepines and LOS are controlled in the model.

Despite the prevalence of treatment-resistant depression, many pharmaceutical companies have abandoned the development of new antidepressants. Experts have attributed this, in part, to the low quality of preclinical tests available in this field, often citing over-reliance on animal behavioral screens, such as the forced swim test (FST). This retrospective review assessed whether compounds tested in the FST by major pharmaceutical companies were shown to have antidepressant effects in humans. Of 109 compounds identified, only 28% had been explored for antidepressant effects in humans. Of these, there were only three for which the FST appeared to positively predict antidepressant efficacy, but none are currently approved to treat any type of depression. With such poor accuracy for identifying novel antidepressants, the FST might not be a useful screening tool for this purpose.

Patients suffering from chronic inflammatory diseases such as psoriasis are prone to develop depressive symptoms. However, within the time constraints of dermatological clinics, depressive symptoms in psoriasis patients are often overlooked and thus underdiagnosed. The Two Questions Test may serve as a quick screening tool for an initial assessment of depressive burden in these patients. We evaluated its usefulness in the clinical context analyzing the records of patients starting systemic treatment for psoriasis with a selective interleukin (IL)23- or IL17A-inhibitor. In a total sample of N = 139 patients, baseline Two Questions Test scores were analyzed together with measures of psoriatic and psychiatric symptoms. In addition, the development of the Two Questions Test scores over the course of the first 28 weeks of treatment was assessed. No association was found between the Two Questions Test scores and skin symptoms measured by the Psoriasis Area and Severity Index and the visibility of skin lesions. However, skin related quality of life analyzed with the Dermatology Life Quality Index was associated with the Two Questions Test scores. In addition, the longitudinal analysis revealed improvement in Two Questions Test outcomes over the course of patients’ treatment. These results indicate the Two Questions Test's usefulness both as an initial screening tool of depressive symptoms, as well as in its use as a sensitive tool for the repeated assessment of depressive symptoms in psoriasis patients.

Objective Headaches are common among youth and are associated with significant negative outcomes. Despite advances in interdisciplinary treatments for youth with chronic pain, research suggests disparities in access to these services. Methods A total of 186 youth (M = 14.19 years old, 70.8% female) presenting to a neurology appointment at a children’s hospital system were screened using the Pediatric Pain Screening Tool (PPST), a brief, validated measure to identify youth that may benefit from additional pain management services. Results Two-thirds of participants (n = 124, 66.7%) screened as medium or high risk on the PPST. Risk categorization did not vary by patient age or sex. A greater proportion of Hispanic/Latino patients were categorized as low-risk relative to non-Hispanic/Latino patients (55.6% vs. 30.1%), and a somewhat lower proportion of patients of color were categorized as medium-risk relative to White patients (14.0% vs. 30.5%). Three-quarters (n = 94, 75.8%) of patients who were screened as medium or high risk were not referred for any additional pain management services. Referrals did not vary by patient age or ethnicity. While not statistically significant, a lower proportion of males received referrals at both medium (8.3% vs. 17.6%) and high levels of risk (15.8% vs. 34.5%), and a greater proportion of youth of color who screened as medium risk received referrals relative to White youth categorized as medium risk (37.5% vs. 10.3%). Conclusion Future research should continue to explore factors influencing decision-making regarding referral to specialized pain management services for youth with headache.

Introduction Because of low pediatric HIV prevalence, more tests are needed to find 1 HIV-positive child compared with adults. In Uganda, the number needed to test (NNT) to find 1 new HIV-positive child was 64 in outpatient departments (OPDs) and 31 through index testing. We aimed to develop and validate a pediatric (1.5-14 years) screening tool to optimize testing approaches. Methods Phase 1 evaluated the performance of 10 screening questions in 14 OPDs using a variable selection algorithm to evaluate combinations of screening questions. Using logistic regression, we identified the number of screening questions with the best predictive accuracy using the receiver operation characteristic curve. Phase 2 validated the proposed tool in 15 OPDs and 7 orphan and vulnerable children programs. We estimated sensitivity, specificity, and NNT accounting for intercluster correlations. Results A total of 3482 children were enrolled. The optimal model included reported HIV-positive maternal status or 2/5 symptoms (sickly in the last 3 months, recurring skin problems, weight loss, not growing well, and history of tuberculosis). The proposed tool had sensitivity of 83.6% [95% confidence interval (CI): 68.1 to 92.4] and specificity of 62.5% (95% CI: 55.0 to 69.4). The tool was validated in a sample of 11,342 children; sensitivity was 87.8% (95% CI: 80.9 to 92.5) and specificity 62.6% (95% CI: 54.8 to 69.7) across OPDs and community sites. In OPDs, sensitivity was 88.1% (95% CI: 80.8 to 92.8) and specificity 69.0% (95% CI: 61.9 to 75.3). The NNT was 43 (95% CI: 28 to 67) across settings and 28 (95% CI: 20 to 38) for OPD. Conclusions This HIV screening tool has high sensitivity and reasonable specificity, increasing testing efficiency and yield for children and adolescents.

Since parental burnout can have detrimental consequences for parents, couples, and children, easy-to-use, reliable, and valid practical tools for the early detection of parental burnout are required. We developed and validated a brief scale to identify burned-out parents and parents at burnout risk. In Study 1, we developed the 5-item Brief Parental Burnout scale (BPBs) based on the gold standard measure of parental burnout, the Parental Burnout Assessment (PBA). We applied Item Response Theory Graded Response Model (GRM) analyses on the data of 1,725 Finnish parents. Compared against the PBA total score, the five selected items showed both high sensitivity and specificity in screening parental burnout. As expected, burned-out parents and those at burnout risk according to the BPBs displayed higher depressive symptoms, lower self-esteem, and more frequent sleep disruptions than non-burned-out parents. In Study 2, we tested the sensitivity and specificity of the BPBs by using both the BPBs and the PBA as independent assessment tools in a sample of 1,088 Finnish parents. In Study 3, the high sensitivity and specificity of the BPBs found in Study 2 were replicated in an independent sample of 104 Belgian parents. We further demonstrated the concurrent validity of the BPBs test score interpretations by showing that burned-out parents, or those at burnout risk, reported higher child neglect and parental violence than non-burned-out parents. Because of its user-friendliness and the strong psychometric properties of its test score, the BPBs is a good candidate to use as a screening tool for parental burnout.

Summary In this editorial, we examine how the STRoke After Surgery (STRAS) screening tool and similar risk scoring systems can be used to identify high-risk patients for postoperative stroke. Specific challenges to develop and implement preventative measures aimed at improving postoperative outcomes are discussed. Finally, we suggest potential future areas of research in this field.

BACKGROUND For cancer patients nearing death, the prediction of their prognosis by physicians is crucial. This study examined the usefulness of the 1-Day Surprise Question (1DSQ). METHODS This study was conducted as part of a multicenter prospective observational study. The physicians answered the 1DSQ "Would I be surprised if this patient died in the next 1 day?" when patients have palliative performance scale (PPS) ≤20. We calculated the sensitivity and specificity of the 1DSQ. Moreover, using multivariate analysis, we evaluated the characteristics of patients who died among those whose physicians answered the 1DSQ as "not surprised". RESULTS Overall, 1,896 patients were enrolled, and 1411 (74.4%) were analyzed between January and December 2017. Among these, 847 (60.0%) patients were placed in the "not surprised" group. The sensitivity, specificity, and positive and negative predictive values of the 1DSQ were 82.0% [95% confidence interval (CI): 77.5-85.8%], 45.5% (95% CI: 44.4-46.4%), 27.4% (95% CI: 25.9-28.7%), and 91.0% (95% CI: 88.9-92.9%), respectively. Multivariate analysis revealed that urine output over last 12 hours

Family history screening to identify individuals at increased risk for hereditary cancers could be a powerful strategy to prevent cancer but is used inconsistently in primary care. The objective was to improve identification of women with at-risk family histories using a point-of-care family history screening tool administered on an electronic tablet device during well-woman appointments. A total of 288 women were invited to participate and 136 women (47.2%) completed the electronic family history screening tool. Significantly more women were identified and referred to the genetics department with the electronic family history screening tool than the standard-of-care paper questionnaire (11.8% versus 0.8%, P < 0.001). There were no statistically significant differences in the proportion of referred women who were evaluated by the genetic counselors, and no pathogenic variants were found with either family history screening method. Implementing innovative self-reporting tools may improve inherited cancer risk detection.

Screening ligands directly binding to an ensemble of intrinsically disordered proteins (IDP) to discover potential hits or leads for new drugs is an emerging but challenging area as IDPs lack well-defined and ordered 3D-protein structures. To explore a new IDP-based rational drug discovery strategy, a differential binding score (DIBS) is defined. The basis of DIBS is to quantitatively determine the binding preference of a ligand to an ensemble of conformations specified by IDP versus such preferences to an ensemble of random coil conformations of the same protein. Ensemble docking procedures performed on repeated sampling of conformations, and the results tested for statistical significance determine the preferential ligand binding sites of the IDP. The results of this approach closely reproduce the experimental data from recent literature on the binding of the ligand epigallocatechin gallate (EGCG) to the intrinsically disordered N-terminal domain of the tumor suppressor p53. Combining established approaches in developing a new method to screen ligands against IDPs could be valuable as a screening tool for IDP-based drug discovery.

BackgroundChest radiographs (CXR) are frequently used as a screening tool for patients with suspected COVID-19 infection pending reverse transcriptase polymerase chain reaction (RT-PCR) results, despite recommendations against this. We evaluated radiologist performance for COVID-19 diagnosis on CXR at the time of patient presentation in the Emergency Department (ED).Materials and MethodsWe extracted RT-PCR results, clinical history, and CXRs of all patients from a single institution between March and June 2020. 984 RT-PCR positive and 1043 RT-PCR negative radiographs were reviewed by 10 emergency radiologists from 4 academic centers. 100 cases were read by all radiologists and 1927 cases by 2 radiologists. Each radiologist chose the single best label per case: Normal, COVID-19, Other – Infectious, Other – Noninfectious, Non-diagnostic, and Endotracheal Tube. Cases labeled with endotracheal tube or non-diagnostic were excluded. Remaining cases were analyzed for label distribution, clinical history, and inter-reader agreement.Results1727 radiographs (732 RT-PCR positive, 995 RT-PCR negative) were included from 1,594 patients (51.2% male, 48.8% female, age 59 ± 19 years). For 89 cases read by all readers, there was poor agreement for RT-PCR positive (Fleiss Score 0.36) and negative (Fleiss Score 0.46) exams. Agreement between two readers on 1,638 cases was 54.2% (373/688) for RT-PCR positive cases and 71.4% (679/950) for negative cases. Agreement was highest for RT-PCR negative cases labeled as Normal (50.4%, n= 479). Reader performance did not improve with clinical history or time between CXR and RT-PCR result.ConclusionAt the time of presentation to the emergency department, emergency radiologist performance is non-specific for diagnosing COVID-19.

OBJECTIVE To determine the prevalence rates of frail, prefrail, robust and mobility disabled older adults living in retirement villages within regional Victoria, Australia. METHODS This cross-sectional, observational study invited residents of retirement villages to complete the self-report questionnaires Fried Frailty Phenotype and Frail Non-Disabled screening tool to classify respondents as frail, prefrail, robust and/or mobility disabled. RESULTS From 212 respondents, prevalence rates of frail and prefrail status were 34% and 35%, respectively. A fifth (20%) of residents were mobility disabled. The prevalence of residents classified as frail or prefrail (ie, not robust) was higher in women (74%) than in men (58%). Classification as not robust increased with increasing age. CONCLUSIONS This study is the first to estimate prevalence rates of frailty and mobility disability in retirement village residents in regional Australia. Findings from this study have potential to inform the development of facilities and programs to support people living in this setting.

Objectives Hantavirus is endemic in the Four Corners region of Arizona, Colorado, New Mexico, and Utah, and hantavirus cardiopulmonary syndrome (HCPS) disproportionately affects the Navajo Nation. We describe the application of a rapid screening tool for identification of HCPS. Methods A rapid screening tool for HCPS was implemented at Tséhootsooí Medical Center (TMC) in collaboration with academic partners. Results Since its implementation in 2016, 20 TMC staff members have been trained to perform this test, and 189 screens for HCPS have been reported. Although hantavirus infection is rare even in high-risk areas, use of this tool resulted in the identification of 4 acute cases of hantavirus infection. Conclusions The results demonstrate the successful implementation of a 5-point screening tool for hantavirus infection in an endemic setting by a laboratory in a small community hospital.

Maternal alloimmunisation against red blood cell antigens can cause haemolytic disease of the fetus and newborn (HDFN). Although most frequently caused by anti-D, since the implementation of rhesus D (RhD) immunoglobulin prophylaxis, other alloantibodies have become more prevalent in HDFN. Recent advances in non-invasive prenatal testing (NIPT) have allowed early prediction of HDFN risk in alloimmunised pregnancies and allow clinicians to focus health resources on those pregnancies that require intervention. This article aims to provide updates on the current status of NIPT in Australia as both a diagnostic and screening tool in pregnancy.

PURPOSE Childhood cancer survivors (CCS) are at risk of developing subsequent malignant neoplasms (SMNs) resulting from exposure to prior therapies. CCS with underlying cancer predisposition syndromes are at additional genetic risk of SMN development. The McGill Interactive Pediatric OncoGenetic Guidelines (MIPOGG) tool identifies children with cancer at increased likelihood of having a cancer predisposition syndrome, guiding clinicians through a series of Yes or No questions that generate a recommendation for or against genetic evaluation. We evaluated MIPOGG's ability to predict SMN development in CCS. METHODS Using the provincial cancer registry (Ontario, Canada), and adopting a nested case-control approach, we identified CCS diagnosed and/or treated for a primary malignancy before age 18 years (1986-2015). CCS who developed an SMN (cases) were matched, by primary cancer and year of diagnosis, with CCS who did not develop an SMN (controls) over the same period (1:5 ratio). Potential predictors for SMN development (chemotherapy, radiation, and MIPOGG output) were applied retrospectively using clinical data pertaining to the first malignancy. Conditional logistic regression models estimated hazard ratios and 95% CIs associated with each covariate, alone and in combination, for SMN development. RESULTS Of 13,367 children with a primary cancer, 317 (2.4%) developed an SMN and were matched to 1,569 controls. A MIPOGG output recommending evaluation was significantly associated with SMN development (hazard ratio 1.53; 95% CI, 1.06 to 2.19) in a multivariable model that included primary cancer therapy exposures. MIPOGG was predictive of SMN development, showing value in nonhematologic malignancies and in CCS not exposed to radiation. CONCLUSION MIPOGG has additional value for SMN prediction beyond treatment exposures and may be beneficial in decision making for enhanced individualized SMN surveillance strategies for CCS.

OBJECTIVE This study evaluated the effects of a social determinants of health (SDH) screening tool and service referral on emergency department (ED) use among patients at a Federally Qualified Health Center primary care clinic. STUDY DESIGN Quasi-experimental. SAMPLE Three-hundred and eleven English-speaking patients 18 years and older. MEASURES The Core 5 SDH screening tool consists of five yes/no items assessing food, housing, utilities, transportation, and safety needs. The number of ED visits 3 months before and after the intervention were collected from electronic health records. INTERVENTION The research team administered the Core 5 SDH screening tool and if desired, referred patients with an identified need for SDH services. RESULTS Approximately 43% of patients reported a SDH need with food insecurity most prevalent (62.2%). The number of ED visits was significantly lower 3 months post-intervention compared to 3 months before for the 125 participants who wanted and received the SDH service referral (IRR = 0.64, 95% CI = 0.41, 0.99) and for the 35 participants who reported receiving some/all of the needed services at the 2-week follow-up (IRR = 0.36, 95% CI = 0.17, 0.76). CONCLUSIONS Addressing patients' SDH needs may reduce ED visits, lower healthcare costs, and ultimately, improve health.

PURPOSE To compare Netra smartphone-based and automated refraction with subjective refraction for screening of refractive errors. METHODS Cross-sectional study at the University of Malaya Medical Centre, Kuala Lumpur. Subjects underwent subjective refraction, then automated refraction, and finally Netra smartphone-based refraction. All results were converted to power vectors (M, J0 and J45) and were analysed using repeated-measures ANOVA and Bland-Altman plots. Sensitivity and specificity were determined. The best cut-off points were determined from ROC curve analysis. P .05), but those between automated and subjective refraction were (0.06 vs 0.11 and 0.07 vs -0.02, p = .004 and p

Background Preoperative assessment of mental health rarely occurs within routine surgery. Any screening tool selected to form part of this process must be deemed practical, acceptable and valid by clinicians and consumers alike. This study aims to assess the acceptability and face validity of two existing mental health screening tools to select one for further development and use in the routine surgical setting. Methods A survey of clinicians and consumers was conducted from October 2020 to March 2021 at a tertiary hospital in Sydney, Australia. Using a Likert scale (1–5, lowest to highest rating), the clinicians evaluated four domains for acceptability and two for validity (six overall) and the consumers four domains for acceptability and one for validity (five overall) on the preoperative use of the amended Kessler Psychological Distress Scale (K10) and the Somatic and Psychological Health Report-12 (SPHERE-12). Consensus was achieved through a rating of 4 or 5 being given by 70% or more of participants with domains able to remain unchanged. Free text responses were analysed into themes. Results A total of 73 participants (51 clinicians; 22 consumers) were included. The K10 received consensus scores (≥ 70%) in four out of six domains for clinicians (4/4 acceptability; 0/2 validity), and all five domains for consumers (4/4 acceptability; 1/1 validity). The SPHERE-12 received consensus scores (≥ 70%) in three domains for clinicians (3/4 acceptability; 0/2 validity), and three domains for consumers (3/4 acceptability; 0/1 validity). Six qualitative themes were described including (1) amendments to tool structure and language; (2) scale response options; (3) difficulty with somatic questions; (4) practicality and familiarity with K10; (5) challenges for specific patient cohorts and (6) timing considerations for patients. Conclusion Adequate acceptability was established for the K10. However further development is required to strengthen its validity for this specific surgical cohort and purpose. Future research to determine the feasibility and acceptability of implementing and using the K10 in the routine surgical setting is now needed.

Background: The influencing factors of diabetic kidney disease (DKD) in Chinese patients with type 2 diabetes mellitus (T2DM) were explored to develop and validate a DKD diagnostic tool based on nomogram approach for patients with T2DM.Methods: A total of 2,163 in-hospital patients with diabetes diagnosed from March 2015 to March 2017 were enrolled. Specified logistic regression models were used to screen the factors and establish four different diagnostic tools based on nomogram according to the final included variables. Discrimination and calibration were used to assess the performance of screening tools.Results: Among the 2,163 participants with diabetes (1,227 men and 949 women), 313 patients (194 men and 120 women) were diagnosed with DKD. Four different screening equations (full model, laboratory-based model 1 [LBM1], laboratory-based model 2 [LBM2], and simplified model) showed good discriminations and calibrations. The C-indexes were 0.8450 (95% confidence interval [CI], 0.8202 to 0.8690) for full model, 0.8149 (95% CI, 0.7892 to 0.8405) for LBM1, 0.8171 (95% CI, 0.7912 to 0.8430) for LBM2, and 0.8083 (95% CI, 0.7824 to 0.8342) for simplified model. According to Hosmer-Lemeshow goodness-of-fit test, good agreement between the predicted and observed DKD events in patients with diabetes was observed for full model (χ2=3.2756, P=0.9159), LBM1 (χ2=7.749, P=0.4584), LBM2 (χ2=10.023, P=0.2634), and simplified model (χ2=12.294, P=0.1387).Conclusion: LBM1, LBM2, and simplified model exhibited excellent predictive performance and availability and could be recommended for screening DKD cases among Chinese patients with diabetes.

Human trafficking, also known as modern-day slavery, is a public health crisis and a growing worldwide crime exploiting approximately 40.3 million victims. A decade ago approximately 79% of human trafficking crimes were related to sexual exploitation and 18% were related to forced labor, but more recent reports show approximately 50% and 38%, respectively. Although sexual exploitation continues to make up the majority of human trafficking crimes, forced labor continues to grow at an alarming rate. The purpose of this paper is 2-fold. First, to empower healthcare providers and community volunteers serving potential victims of human trafficking in traditional and nontraditional settings with human trafficking identification training. This education should include the use of a validated human trafficking screening tool and the timely provision of resources. Second, to guide professional nurses in the holistic approach to caring for potential victims of human trafficking. The core values of holistic nursing practice and Watson's Theory of Human Caring are the pillars guiding mindful and authentic nursing care. Merging evidence-based practice with holistic care will boost victim identification and rescue.

Traditional review of EEG for seizure detection requires time and the expertise of a trained neurophysiologist; therefore, it is time- and resource-intensive. Quantitative EEG (qEEG) encompasses a variety of methods to make EEG review more efficient and allows for nonexpert review. Literature supports that qEEG is commonly used by neurophysiologists and nonexperts in clinical practice. In this review, the different types of qEEG trends and spectrograms used for seizure detection in adults, from basic concepts to clinical applications, are discussed. The merits and drawbacks of the most common qEEG trends are detailed. The authors detail the retrospective literature on qEEG sensitivity, specificity, and false alarm rate as interpreted by experts and nonexperts alike. Finally, the authors discuss the future of qEEG as a useful screening tool and speculate on the trajectory of future investigations in the field.

The diagnosis of depression or anxiety is often difficult to establish in patients with Chronic Obstructive Pulmonary Disease (COPD) as many physical symptoms are shared. There is no consensus on a screening tool for depression and anxiety in patients with COPD. The aim of this systematic review is to review screening tools for depression and anxiety suitable for application among patients with COPD in the clinical setting. A systematic review was made using predefined search terms and eligibility criteria. Of 274 initially screened articles, seven studies were found eligible. Three depression screening tools (BASDEC, BDI-II and HADS-D) had a sensitivity of 100% and a specificity >85%. The best performing anxiety screening tool (GAI) had a sensitivity of 86% and a specificity of 78%. Three screening tools had acceptable psychometric properties according to sensitivity and specificity to detect depression among patients with COPD, but the screening tools for anxiety were of less quality. Further research in and validation of the screening tools is needed to recommend one specific tool.

Background Intimate partner violence (IPV) is a major public health problem with harmful consequences. In Australia, there is no national standard screening tool and screening practice is variable across states. The objectives of this study were to assess in the antenatal healthcare setting: i) the validity of a new IPV brief screening tool and ii) women’s preference for screening response format, screening frequency and comfort level. Methods One thousand sixty-seven antenatal patients in a major metropolitan Victorian hospital in Australia completed a paper-based, self-administered survey. The survey included four screening items about whether they were Afraid/Controlled/Threatened/Slapped or physically hurt (ACTS) by a partner or ex-partner in the last 12 months; and the Composite Abuse Scale (reference standard). The ACTS screen was presented firstly with a binary yes/no response format and then with a five-point ordinal frequency format from ‘never’ (0) to ‘very frequently’ (4). The main outcome measures were test statistics of the four-item ACTS screening tool (sensitivity, specificity, predictive values, and area under the curve) against the reference standard and women’s screening preferences. Results Twelve-month IPV prevalence varied depending on the ACTS response format with 8% (83) positive on ACTS yes/no format, 12.8% (133) positive on ACTS ordinal frequency format and 10.5% (108) on the reference Composite Abuse Scale. Overall, the ACTS screening tool demonstrated clinical utility for the ordinal frequency format (AUC, 0.80; 95% CI = 0.76 to 0.85) and the binary yes/no format (AUC, 0.74, 95% CI = 0.69 to 0.79). The frequency scale (66%) had greater sensitivity than the yes/no scale (51%). The positive and negative predictive values were 56 and 96% for the frequency scale and 68 and 95% for the yes/no scale. Specificity was high regardless of screening question response options. Half (53%) of the women categorised as abused preferred the yes/no scale. Around half of the women (48%, 472) thought health care providers should ask pregnant women about IPV at every visit. Conclusions The four-item ACTS tool (using the frequency scale and a cut-off of one on any item) is recommended for written self-administered screening of women to identify those experiencing IPV to enable first-line response and follow-up.

Introduction Using pediatric social determinants of health screening data from a large medical system, we explored social needs dislosures and identified which needs were associated with resource connection requests. Method Data came from records of outpatient pediatric patients (0–18 years) seen between October 2018 and March 2020 (39,251 encounters). We assessed percent of encounters where families (1) indicated a social need, and (2) requested a resource connection. We conducted multivariable logistic regression to identify which needs were associated with resource connection requests. Results Among all encounters, 8% indicated a need and 2% requested a resource connection. Among families indicating a need, needs associated with resource requests included: housing (odds ratio [OR], 3.49 [2.42–5.03]), employment (OR, 3.15 [2.21–4.50]), food (OR, 1.89 [1.41–2.52]), and transportation (OR, 1.82 [1.30–2.56]). Discussion Families seldom requested resource connections to address social needs. Better understanding families’ interests in receiving assistance is an important next step in pediatric social determinants of health screening system development.

Recommendations for social distancing and avoidance of mass gatherings during the COVID-19 pandemic have correlated with increased depressive symptoms in some individuals, such as loss of interest in daily activities, sleeplessness, or sadness. Perinatal depression screening using established, validated tools can aid with early diagnosis, guide management strategies, and optimize outcomes for pregnant women and their families. Identifying at-risk patients early in pregnancy and implementing a plan of care with appropriate mental health resources such as counseling or therapy have been shown to decrease clinical depression by more than 40%., RNs are uniquely positioned to identify depressive or anxiety symptoms during pregnancy and in the postpartum period. This article discusses use of the Edinburgh Postnatal Depression Scale to help recognize patients at risk for perinatal depression.

Aim To determine and compare the level of prevalence of intimate partner violence (IPV) at 12 months before pregnancy and during pregnancy and to identify the predictors of physical IPV. Design A cross‐sectional, correlational design was used for data collection and analysis. Methods Convenience sampling was used to recruit 247 women for the study. The women's IPV experience was measured by the Arabic version of the World Health Organization's Domestic Violence Questionnaire Screening Tool. Results The women reported that they experienced substantial levels of different types of IPV during pregnancy: 93.1% control, 66% psychological, 31.2% physical and 8.9% sexual. The levels of psychological, physical and sexual IPV during pregnancy were statistically significantly lower than those before pregnancy. In the case of physical IPV, women's age and verbal fighting were independent positive predictors, while women's educational level, husbands' educational level and level of mutual understanding were independent negative predictors. It is therefore recommended that policymakers focus on providing marital advice and marriage counselling and on empowering women by education in order to tackle IPV during pregnancy.

The predictive ability and efficiency of inpatient harm screening tools is unclear. We performed a retrospective analysis of approximately 25 000 people admitted to our hospital in 2019. We found that the discriminatory ability of the harm screening tools was at best moderate and could be attributed to one or two questions that overlapped with each other in the harm they predicted.

The effect of malnutrition on outcomes after carotid artery stenting (CAS) is not well known. This study reports the relationship between malnutrition and post-procedure 30-day major adverse events (MAEs). A total of 978 patients hospitalized for CAS were enrolled in the study. Controlling nutritional status (CONUT) score, the nutritional risk index (NRI), and the prognostic nutritional index (PNI) were calculated. MAEs (myocardial infarction, stroke/transient ischemic attack and mortality) were compared. According to the CONUT score, NRI, and PNI, 9.4%, 41%, and 11.4% patients were moderately or severely malnourished, respectively; 74.8% were at least mildly malnourished by at least 1 score. Forty-seven patients (4.8%) had a post-procedure 30-day MAE. Continuous classifications of the indexes were independently associated with higher MAE. CONUT showed the highest predictive ability, whereas NRI had the lowest (C-index: CONUT, 0.701; NRI, 0.681; PNI, 0.688). According to categorical classification of indexes, only CONUT and PNI showed predictive ability for MAE. Malnutrition assessment could identify patients with CAS at elevated risk for MAE. CONUT, NRI, and PNI continuous scores were independent prognostic factors for the post-procedure 30-day MAE. According to our study, CONUT showed the highest predictive ability.

A concussion occurs when a direct or indirect force is transmitted to the brain, causing a change in brain function. Given that approximately half the brain circuits are involved in vision and the control of eye movements, a concussion frequently results in visual symptoms. Ophthalmic abnormalities are helpful in the assessment of acute concussion, identified by rapid automized naming tasks and eye movement assessments. In particular, convergence, eye-tracking and the vestibular-ocular motor screening tool may be used. For patients suffering from post-concussion syndrome more than three months from the original injury, abnormalities may be found in convergence, accommodation and smooth pursuit. Orthoptic exercises are useful rehabilitation tools to allow patients to return to school, work and recreation. This article provides a brief overview of concussion as it relates to vision and ophthalmic practice.

The Female Sexual Function Index is a powerful screening tool for female sexual dysfunction extensively used worldwide. Nonetheless, its factorial structure and psychometric properties have been tested almost exclusively with heterosexual samples. The current study aimed to testing the original factorial structure, reliability and temporal stability in two samples of women (heterosexual and lesbian), and to assess the measurement invariance across sexual orientation. An online sample of 752 Portuguese women (376 lesbian women and 376 heterosexual women) recruited between May 2012 and 2013 participated in the study and completed a sociodemographic questionnaire and the FSFI. For temporal stability, 30 Portuguese women were recruited online in May 2017. Confirmatory factor analysis, reliability analysis and temporal stability were assessed independently for each sample. Measurement invariance (configural, metric, and scalar) was also assessed. Main findings for both samples corroborate the six-factor structure and revealed excellent levels of temporal stability, with Cronbach alphas and McDonalds Omega of .95 for heterosexual sample, and .96 for lesbian women sample. Results corroborate measurement invariance (configural, metric, and scalar) across sample type. Overall, the FSFI revealed a good-fit for the six-factor model in both heterosexual and women sample, with excellent levels of reliability and temporal stability, and showed measurement invariance across sexual orientation. These findings support the use of the FSFI with lesbian women.

PURPOSE OF REVIEW This article reviews available assessment instruments for three of the feeding and eating disorder diagnostic categories: avoidant restrictive food intake disorder (ARFID), pica, and rumination disorder (RD). It includes an overview of the current status of screening tools, questionnaire measures, and diagnostic instruments. RECENT FINDINGS Screening instruments are available for all three disorders; however, for pica and RD, these typically include single screening items only and do not cover any specific features of these presentations. Only one questionnaire suitable for clinical populations is included, covering ARFID only. Standardized diagnostic interviews are limited to two covering both pica and RD, only one of which provides further clinical information. Of the five diagnostic instruments for ARFID described here, two include diagnostic items as well as allowing more detailed assessment of clinical features. SUMMARY There are a limited number of assessment measures available for all three disorders, with instruments for ARFID being the greatest in number and widest in terms of scope. A commonly encountered difficulty is that many assessment instruments do not adequately cover diagnostic exclusion criteria, which raises the likelihood of false positive findings. All currently available measures require further study to determine their reliability and validity.

Measuring the dietary intakes of individuals for research and monitoring purposes is notoriously challenging and is subject to both random and systematic measurement error. In this review, the strengths and limitations of current methods to assess dietary and supplemental exposures are described. Traditional methods of dietary assessment include food records, food frequency questionnaires, 24-hour recalls, and screening tools; digital and mobile methods that leverage technology are available for these traditional methods. Ultimately, the choice of assessment method is dependent upon the research question, the study design, sample characteristics, and the size of the sample, to name just a few. Despite their challenges, dietary assessment tools are an important dimension of nutrition research and monitoring.

Reliably diagnosing autism spectrum disorders (ASD) in adulthood poses a challenge to clinicians due to the absence of specific diagnostic markers. This study investigated the potential of interpersonal synchrony (IPS), which has been found to be reduced in ASD, to augment the diagnostic process. IPS was objectively assessed in videos of diagnostic interviews in a representative referral population from two specialized autism outpatient clinics. In contrast to the current screening tools that could not reliably differentiate, we found a significant reduction of IPS in interactions with individuals later diagnosed with ASD (n = 16) as opposed to those not receiving a diagnosis (n = 23). While these findings need to be validated in larger samples, they nevertheless underline the potential of digitally-enhanced diagnostic processes for ASD.

AIM To explore the experiences of Jordanian nurses regarding the psychosocial care needs of children with thalassaemia and their families. DESIGN A descriptive phenomenological approach was employed. METHODS A purposive sampling strategy was used to select 10 nurses who had experience in caring for children with thalassaemia. Unstructured, face-to-face interviews were conducted. Coliazzi's data analysis process was applied. RESULTS The analysis revealed three major themes: (1) valuing psychosocial support; (2) caring for paediatric patients needs certain competencies in nurses and (3) barriers to providing psychosocial care. Nurses expressed the importance of providing psychosocial care. A lack of specialists in psychosocial care as well as a lack of screening tools, and entertainment facilities for children was identified to be impeding effective psychosocial care. Implementing training programmes for nurses concerning providing psychosocial care and making the appropriate changes in nursing curricula at the educational level are recommended.

PurposeValid and reliable screening tools are needed to improve early detection and optimize developmental outcomes for toddlers at risk for autism spectrum disorder (ASD). The current study aimed to evaluate the utility of the Systematic Observation of Red Flags (SORF) for ASD at 12 months of age in a sample of high-risk infant siblings of children with ASD.MethodAs part of a prospective, longitudinal study, we examined the sensitivity and specificity of the SORF at 12 months for predicting a diagnosis of ASD at 24 months in a sample of 122 infants, 31 of whom were diagnosed with ASD.ResultsThe optimal SORF Composite cutoff score of 18 correctly identified 24 of the 31 twelve-month-olds who were diagnosed with ASD, yielding a sensitivity of .77 and a specificity of .76. The optimal SORF Red Flags cutoff score of 7 correctly identified 20 of the 31 infants, yielding a sensitivity of .65 and a specificity of .75.ConclusionThis preliminary study demonstrates the potential of the SORF as an effective observational screening measure for 12-month-olds at risk for ASD with good discrimination, sensitivity, and specificity.

In this study, we evaluated the performance of the flow cytometer-based Sysmex UF-5000 automated urine analyzer as a screening tool for ruling out urinary tract infections in elderly patients presenting at the emergency department. A total of 1119 unselected patient samples (including 544 samples from elderly patients) submitted for urine culture were included in this study. Samples were measured on UF-5000 and dipsticks and the results were compared with interpretation of culture results, which is the gold standard. We obtained a diagnostic sensitivity of 99% and specificity of 51% with a low rate of false negatives (0.2%) and a negative predictive value of 99% at 108 colony forming bacteria/L (CFB/L). A bacterial count ≥ 50x106/L or yeast like cells ≥ 25x106/L was used as the cutoff value. At this cutoff value, 30% of the urine cultures would have been redundant. This resulted in 35% false positive samples, mainly due to particle contamination or nongrowing bacteria. In comparison, at best, the dipsticks have a diagnostic sensitivity of 89%, a specificity of 52% and a negative predictive value of 92% at 108 CFB/L.
