Abstract
OBJECTIVE Essential vocal tremor (EVT) manifests as nearly rhythmic modulations of fundamental frequency (fo) and intensity and causes a shaky voice. Although research on behavioral therapy for EVT is limited, previous studies have shown that a breathy voice reduces the perception of simulated EVT and might be an effective compensatory strategy. The current study aimed to measure the acoustical and perceptual effects of a breathy voice strategy in speakers with EVT. STUDY DESIGN A single-case experimental design (SCED) was used to investigate acoustical effects, and a pair comparison listening task was used to investigate perceptual effects. METHODS Three participants with EVT matched five different levels of breathiness produced by a computational model. Acoustical analyses of the rate and extent of fo and intensity modulation were performed to estimate EVT severity for baseline and treatment trials. Statistical analyses were completed using Tau-U. Twenty novice listeners participated in the perceptual study to determine if treatment trials sounded less "shaky" than baseline trials. Statistical analyses were completed using one sample t tests. RESULTS The acoustical effects were variable across different levels of breathiness for all three participants. All participants were able to adjust their levels of breathiness based on auditory models and verbal cues but did not achieve the target levels of breathiness. Listeners did not perceive the breathy trials to be less "shaky" than baseline trials for any level of breathiness. CONCLUSION The breathy voice strategy had variable effects on the acoustical measures of EVT, supporting the use of a single-case experimental design to investigate the effectiveness of behavioral treatment for EVT. Listeners perceived breathy trials to be "shakier" than baseline trials, which was inconsistent with our hypothesis and previous studies of EVT. Future research should evaluate the use of a breathy voice in speakers with confirmed laryngeal tremor, optimize cueing for breathiness, and provide more opportunities to practice the breathy strategy.

Abstract
Background and Objectives Previous studies have found that pain is associated with fall worry among community-dwelling older people. However, both pain and fall worry are poorly understood and underaddressed among community-dwelling older people with cognitive impairment (CI). It is essential to examine the association between pain and fall worry, and how sociodemographic and health characteristics may shape fall worry among this subgroup. Research Design and Methods We used data from the 2015 National Health and Aging Trends Study (analytic sample: n = 1150 community-dwelling older people with CI; were self-interviewed; mean age: 81; age range: 65-107). The number of pain sites in the prior month was assessed by presenting a card listing common pain sites (eg, back, knees). Two questions assessed past-month fall worry, "did you worry about falling down" and "did this worry ever limit your activities." Following descriptive statistics, we fit multinomial logistic regression models to examine the associations between different pain characteristics (number of sites, severity, location) and non-activity-limiting and activity-limiting fall worry. Results Non-activity-limiting fall worry was endorsed by 21.1% and activity-limiting fall worry by 13.6% of community-dwelling older people with CI. After adjusting for sociodemographic characteristics and fall-worry-related covariates, multinomial logistic regression analysis found that a greater number of pain sites (relative risk ratio [RRR] = 1.22, 95% Confidence Interval [95% CI] = 1.12-1.33, p <.001) and severe pain (RRR = 2.05, 95% CI = 1.12-3.75, p = .020) was associated with activity-limiting fall worry. Both lower body (knee, foot, and leg) and upper body (hand, wrist, shoulder, neck, and stomach) pain were found to be associated with a high risk of activity-limiting fall worry. Discussion and Implications These findings suggest pain and fall worry are common among community-dwelling older people with CI and can be elicited directly from those who are communicative. Fall prevention for this population should prioritize pain management to mitigate activity-limiting fall worry because activity limitation increases the risk of falls.

Abstract
Background: Ancestry is often viewed as a more objective and less objectionable population descriptor than race or ethnicity. Perhaps reflecting this, usage of the term "ancestry" is rapidly growing in genetics research, with ancestry groups referenced in many situations. The appropriate usage of population descriptors in genetics research is an ongoing source of debate. Sound normative guidance should rest on an empirical understanding of current usage; in the case of ancestry, questions about how researchers use the concept, and what they mean by it, remain unanswered. Methods: Systematic literature analysis of 205 articles at least tangentially related to human health from diverse disciplines that use the concept of ancestry, and semi-structured interviews with 44 lead authors of some of those articles. Results: Ancestry is relied on to structure research questions and key methodological approaches. Yet researchers struggle to define it, and/or offer diverse definitions. For some ancestry is a genetic concept, but for many-including geneticists-ancestry is only tangentially related to genetics. For some interviewees, ancestry is explicitly equated to ethnicity; for others it is explicitly distanced from it. Ancestry is operationalized using multiple data types (including genetic variation and self-reported identities), though for a large fraction of articles (26%) it is impossible to tell which data types were used. Across the literature and interviews there is no consistent understanding of how ancestry relates to genetic concepts (including genetic ancestry and population structure), nor how these genetic concepts relate to each other. Beyond this conceptual confusion, practices related to summarizing patterns of genetic variation often rest on uninterrogated conventions. Continental labels are by far the most common type of label applied to ancestry groups. We observed many instances of slippage between reference to ancestry groups and racial groups. Conclusion: Ancestry is in practice a highly ambiguous concept, and far from an objective counterpart to race or ethnicity. It is not uniquely a "biological" construct, and it does not represent a "safe haven" for researchers seeking to avoid evoking race or ethnicity in their work. Distinguishing genetic ancestry from ancestry more broadly will be a necessary part of providing conceptual clarity.

Abstract
A wide range of research uses patterns of genetic variation to infer genetic similarity between individuals, typically referred to as genetic ancestry. This research includes inference of human demographic history, understanding the genetic architecture of traits, and predicting disease risk. Researchers are not just structuring an intellectual inquiry when using genetic ancestry, they are also creating analytical frameworks with broader societal ramifications. This essay presents an ethics framework in the spirit of virtue ethics for these researchers: rather than focus on rule following, the framework is designed to build researchers' capacities to react to the ethical dimensions of their work. The authors identify one overarching principle of intellectual freedom and responsibility, noting that freedom in all its guises comes with responsibility, and they identify and define four principles that collectively uphold researchers' intellectual responsibility: truthfulness, justice and fairness, anti-racism, and public beneficence. Researchers should bring their practices into alignment with these principles, and to aid this, the authors name three common ways research practices infringe these principles, suggest a step-by-step process for aligning research choices with the principles, provide rules of thumb for achieving alignment, and give a worked case. The essay concludes by identifying support needed by researchers to act in accord with the proposed framework.

Abstract
BackgroundGlucocorticoids (GCs) are a key treatment for inflammatory rheumatic diseases, but they cause a wide range of adverse side-effects which are of concern both to patients and clinicians.ObjectivesThe objective of this study was to explore the impact of GC therapy on health-related quality of life (HRQoL) during treatment for rheumatic diseases, as a basis for development of a Patient-Reported Outcome Measure (PROM) to be used in clinical trials and practice.MethodsPatients from the UK, USA and Australia who were treated with GCs in the last two years for a rheumatic condition were invited to take part in semi-structured qualitative interviews. Purposive sampling was used to include participants with a range of demographic and disease features. A steering committee of patient research partners, clinicians and methodologists devised an initial conceptual framework, which informed interview prompts and cues. Interviews were carried out by experienced qualitative researchers who encouraged participants to tell their stories and talk about the effects, both adverse and beneficial, of their experiences and perceptions of treatment with GCs, to identify salient physical and psychological symptoms and aspects of HRQoL. The interview data were organised using NVivo, and inductive analysis identified initial themes and domains. Candidate questionnaire items were developed and refined using cognitive interviewing, linguistic assessment, and input from patient research partners.ResultsSixty semi-structured qualitative interviews were conducted (UK n=34, USA n=10, Australia n=16). Mean participant age was 58 years; 39 (66.1%) were female. Purposive sampling of participants provided a broad range of demographic features, GC dosages and inflammatory rheumatic conditions, with 27% having connective tissue disease, 25% inflammatory arthritis, 30% systemic vasculitis and 16% other rheumatic conditions.Initial domains were developed to identify key themes relating to treatment using GCs and their impact on HRQoL; see Figure 1.Figure 1.Steroid PRO Initial ThemesA long-list of 134 initial candidate questionnaire items was developed from the individual themes. These items were reviewed by a qualitative working group of patient research partners, researchers and clinicians to reduce duplication and ambiguity of items. The resulting 62 items were tested and refined by piloting with patient research partners, iterative rounds of cognitive interviews with patients with a range of rheumatic conditions from the UK, USA and Australia, and a linguistic translatability assessment, to define a draft questionnaire of 40 items.ConclusionThis international qualitative study underpins the development of candidate items for a treatment-specific PROM for patients with rheumatic diseases. The draft questionnaire is currently being tested in an online large-scale survey to determine the final scale structure and measurement properties using Rasch analysis, factor analysis, test-retest, comparison with EQ5D, and known groups analysis.Disclosure of InterestsSusan Bridgewater Grant/research support from: Vifor Pharma, Michael A Shepherd Grant/research support from: Vifor Pharma, Jill Dawson: None declared, Pamela Richards: None declared, Christine Silverthorne: None declared, Mwidimi Ndosi: None declared, Celia Almeida: None declared, Rachel J Black: None declared, Jonathan T.L.

Abstract
BackgroundImmune checkpoint inhibitors (ICI) have markedly improved the treatment of many advanced cancers; however, they can result in immune-related adverse events (irAE) including ICI arthritis (ICI-A). ICI-A often resembles rheumatoid arthritis (RA) and ~9% of ICI-A patients are anti-citrullinated peptide antibody (ACPA) positive. In RA, ACPA epitope expansion occurs over the years prior to onset of clinical disease. In this study we examined the degree of ACPA epitope expansion in seropositive ICI-A patients in order to determine whether it is similar to early RA, or more suggestive of the pre-clinical phase of disease1.ObjectivesTo compare the number of ACPA epitopes targeted in seropositive ICI-A versus RA.MethodsWe used clinical data and serum from 12 ACPA+ ICI-A patients enrolled in a prospective registry and 39 ACPA+ RA patients enrolled in the CATCH-US early RA cohort. ACPA screening was done using a commercial ELISA (positive >20 units/mL). A custom, bead-based antigen array was used to identify antibody reactivities to 16 putative RA associated citrullinated proteins. Synovial fluid (SF) samples from 3 of the ICI-A patients were also tested using the bead-based microarray. Hierarchical clustering software was used to create heatmaps to identify ACPA levels. Z-scores for fluorescence intensity were also calculated separately for each peptide, and a fluorescence level above the mean (Z-score>0) was defined as a positive ACPA. The number of positive epitopes for each patient was determined and compared categorically between the ICI-A and RA patients using Fischer’s exact test.ResultsCharacteristics of ICI-A and early RA patients are listed in Table 1. Compared to RA patients, ICI-A patients were older (mean 71 years vs. 48 years), more likely to have ever smoked (67% vs. 36%) and less likely to have positive rheumatoid factor (RF) (8% vs. 69%). Median symptom duration for ICI-A patients was 3.7 months compared to 6.7 months in RA patients. The median ACPA titer was lower in ICI-A patients than RA patients (42 units/mL vs. 250 units/mL). As demonstrated in Figure 1, lower signal intensities (level of ACPA) and a lower number of distinct ACPA epitopes were seen in the serum of ICI-A patients compared to RA patients. Of ICI-A patients, 67% were positive for 0-4 ACPA epitopes, 8% for 5-10 epitopes and 25% for >10 epitopes, as opposed to 23% of RA patients positive for 0-4 epitopes, 36% for 5-10 epitopes, and 41% for >10 epitopes (p=0.02). The one ICI-A patient who was also RF positive had 12 positive ACPA epitopes. There was no significant difference in the number of ACPA epitopes in ICI-A patients who were smokers vs. nonsmokers, RA-like vs. PMR-like, or who received ICI combination vs. ICI monotherapy. In the 3 ICI-A patients with synovial fluid samples, SF ACPA was not demonstrated.Table 1.Baseline Characteristics of ACPA+ ICI-A and RA PatientsICI-A (N=12)Early RA (N=39)Age in years, mean (SD)71.0 (8.3)48.2 (14.6)Female Sex7 (58%)33 (85%)White/Caucasian9 (75%)27 (69%)Symptom Duration in months, median [IQR]3.7 [1.0,11.3]6.7 [4.0,9.7]RF Positive1 (8%)27 (69%)ACPA level (units/mL), median [IQR]42.2 [29.4,70.5]250 [107.5,251.0]Obese (BMI≥30)3 (25%)9 (23%)Current/Past Smoker8 (67%)14 (36%)Cancer Typeǂ Melanoma4 (33%) Renal Cell Carcinoma3 (25%)ICI Regimen PD-1/PD-L17 (58%) CTLA-4+PD-15 (42%)ICI-A Phenotype RA-like9 (75%) PMR-like3 (25%)ǂOther cancer types in ICI-A patients included urothelial carcinoma (n=2), non-small cell lung cancer (n=2), and head and neck cancer (n=1).Figure 1.Heat Map of ACPA repertoire in RA Patients and ICI-A Patients.ConclusionICI-A patients had lower ACPA titers and targeted fewer ACPA epitopes than early RA patients. It remains to be determined if ICI-A represents an accelerated model of RA pathogenesis with ICI triggering an early transition from pre-clinical to clinical disease. This would require sequential sampling and analysis.References[1]Sokolove J. et al.

Abstract
BackgroundElectronic patient portals, such as MyChart by Epic, allow patients to view their medical records, request medication refills, and communicate with their health care providers. Factors associated with portal use include being younger, female, White, having private insurance, and having chronic illness.1The Hospital for Special Surgery (HSS) rheumatology clinic serves primarily patients with public insurance (Medicaid, which insures low-income adults, and Medicare, which insures adults >65 years old and those with eligible chronic illness/disability). These patients may be at increased risk for poor health outcomes due to clinical and socioeconomic factors and they are less likely to use MyChart than patients seen in HSS private practices. Increased MyChart use may benefit this high-risk group and improve health equity.ObjectivesThis study aims to identify characteristics associated with MyChart activation and reasons for its underutilization among patients seen in the HSS rheumatology clinic.MethodsWe identified all patients aged ≥ 18 years seen in the HSS rheumatology clinic at least twice between January 15, 2019 and January 14, 2021, with at least one visit occurring between July 15, 2020 and January 14, 2021. MyChart status (active vs. inactive) and sociodemographic and clinical variables were extracted from the electronic health record (EHR). We used chi-square tests and t-tests to compare characteristics between patients with and without active MyChart; p-value <0.05 was considered significant (Table 1). In addition, 10 rheumatology fellows were prompted on 3 occasions over 6 weeks to informally survey their own clinic patients with inactive MyChart accounts by asking: “What is your primary reason for not using MyChart?”.Table 1.Baseline Characteristics of Hospital for Special Surgery Rheumatology Clinic Patients Stratified by MyChart Activation StatusMyChart Active (N=726)MyChart Inactive (N=501)p-valueAge, yrs - Mean (SD)50.3 (15.6)60.0 (15.3)<0.01Female - N (%)601 (82.8)412 (82.2)0.80Race - N (%)0.37•White/Caucasian275 (37.9)184 (36.7)•Black/African American185 (25.5)135 (27.0)•Asian58 (8.0)25 (5.0)•Other189 (26.0)145 (28.9)•Unknown18 (2.5)11 (2.2)Ethnicity - N (%)0.27•Hispanic/Latino294 (40.5)226 (45.1)•Not Hispanic/Latino422 (58.1)268 (53.5)•Unknown10 (1.4)7 (1.4)Preferred language - N (%)<0.01•English611 (84.2)332 (66.3)•Spanish72 (9.9)134 (26.8)•Other43 (5.9)35 (7.0)Needs interpreter - N (%)106 (14.6)156 (31.1)<0.01ResultsThere were 1,227 patients included (93.2% with Medicaid and/or Medicare insurance). Compared to patients with inactive MyChart (42.9%), those with active MyChart (57.1%) were younger (50.3 ± 15.6 vs. 60.0 ± 15.3 years, p<0.01). The majority of patients in both groups was female. There was no significant difference in race or ethnicity between groups. Patients without active MyChart were less likely to identify English as their preferred language and more likely to require an interpreter for clinic visits (Table 1).The rheumatology fellows collectively asked 16 clinic patients with inactive MyChart their primary reason for non-use. The most commonly cited reason was difficulty using the technology (n=8; 50.0%); others included visual impairment (n=2; 12.5%), preference for using the telephone (n=2; 12.5%), concerns about security/spam (n=2; 12.5%), not having a smart phone/computer (n=1; 6.3%), and having a language barrier (n=1; 6.3%).ConclusionIn the HSS rheumatology clinic, patients who did not have active MyChart were older and less likely to be English-speaking than those who did. The most common barrier to MyChart use reported by patients was difficulty with the technology. This pilot data suggests a need for interventions to facilitate patient-provider communication, specifically targeting older and non-English-speaking rheumatology clinic patients, with the goal of advancing patient engagement and health equity.References[1]Ancker JS, et al.

Abstract
Background:Glucocorticoids (GCs) are a key treatment for the autoimmune rheumatic diseases; however, they produce numerous physical and psychological side effects.1 The Outcome Measures in Rheumatology (OMERACT) Glucocorticoid Working Group have identified that there are no Patient Reported Outcome Measures (PROMs) for assessing the impact of systemic GC therapy across multiple rheumatic diseases from the patient’s perspective.2,3Objectives:The aim is to explore the impact of GCs on the symptoms and health-related quality of life of adults with rheumatic inflammatory diseases, to inform items for inclusion in a PROM. Key considerations will include patient perceptions of GC therapy at diagnosis and over the course of treatment, for use in future randomised controlled trials or in clinical practice.Methods:An international steering committee comprising researchers, rheumatology clinicians, methodologists and patient partners in the UK, Australia and USA developed an initial conceptual framework informed by a review of the literature. Semi-structured interviews were conducted in each country with patients who had an autoimmune rheumatic disease and had received GC therapy. The interviews explored salient aspects of health-related quality of life associated with being treated with GCs.Results:Interviews have been completed in three continents with patients who had a range of demographic features, rheumatological conditions and duration and dosage of GC therapy. Figure 1 shows the initial conceptual framework for developing the GC PROM (Steroid PRO).Figure 1.Conclusion:This conceptual framework will act as an evolving guide in the development of a PROM for assessing patients’ perspectives of systemic glucocorticoid therapy. Future work will include inductive analysis of qualitative transcripts to inform candidate questionnaire items, cognitive interviewing, linguistic translatability assessment, and an international validation survey to define the final PROM questionnaire and its measurement properties.References:[1]Cheah JTL, Robson JC, Black RJ, et al.

Abstract
OBJECTIVE To compare outcomes before and after implementation of medical abortion (termination of pregnancy) without ultrasound via telemedicine. DESIGN Cohort analysis. SETTING The three main abortion providers. POPULATION OR SAMPLE Medical abortions at home at ≤69 days' gestation in two cohorts: traditional model (in-person with ultrasound, n = 22 158) from January to March 2020 versus telemedicine-hybrid model (either in person or via telemedicine without ultrasound, n = 29 984, of whom 18 435 had no-test telemedicine) between April and June 2020. Sample (n = 52 142) comprises 85% of all medical abortions provided nationally. METHODS Data from electronic records and incident databases were used to compare outcomes between cohorts, adjusted for baseline differences. MAIN OUTCOME MEASURES Treatment success, serious adverse events, waiting times, gestation at treatment, acceptability. RESULTS Mean waiting time from referral to treatment was 4.2 days shorter in the telemedicine-hybrid model and more abortions were provided at ≤6 weeks' gestation (40% versus 25%, P < 0.001). Treatment success (98.8% versus 98.2%, P > 0.999), serious adverse events (0.02% versus 0.04%, P = 0.557) and incidence of ectopic pregnancy (0.2% versus 0.2%, P = 0.796) were not different between models. In the telemedicine-hybrid model, 0.04% were estimated to be over 10 weeks' gestation at the time of the abortion; all were completed safely at home. Within the telemedicine-hybrid model, effectiveness was higher with telemedicine than in-person care (99.2% versus 98.1%, P < 0.001). Acceptability of telemedicine was high (96% satisfied) and 80% reported a future preference for telemedicine. CONCLUSIONS A telemedicine-hybrid model for medical abortion that includes no-test telemedicine and treatment without an ultrasound is effective, safe, acceptable and improves access to care. TWEETABLE ABSTRACT Compelling evidence from 52 142 women shows no-test telemedicine abortion is safe, effective and improves care.

Abstract
Eventration of diaphragm is an abnormal elevation of diaphragmatic musculature while retaining normal attachments to the sternum, ribs and dorsolumber spine. It is a rare anomaly where the continuity of diaphragm remains intact. Pathological process can affect either all or only a portion of hemidiaphragm. Symptoms vary according to size of the defect. Large defect may mimic diaphragmatic hernia. The present case represents a full term female newborn that developed respiratory distress, cyanosis and feeding difficulties since 1st day of life. Clinical features and chest imaging of this case was assumed to be left sided diaphragmatic hernia which was found wrong in the operation theater. She was found to have left sided eventration of diaphragm to create symptom. Successful plication of ipsilateral diaphragm was done on 13th day of life. Supervised post operative ventilatory support along with other postoperative care improved the condition of this neonate. A large defect with eventration of diaphragm may be life threatening but a timely good management can save neonate from such condition.

Abstract
Squamous cell carcinoma antigen (SCC Ag) was estimated in 30 controls, in 16 patients with benign lesions of the uterine cervix, and in 51 patients with uterine cervical carcinoma. The rate of positivity of the antigen among the cancer patients was 87% (N = 49). SCC Ag estimations were of no diagnostic value, since 37% of patients with bening lesions had elevated levels compared to controls. SCC Ag was highly correlated to histologic subtype. The highest values were obtained in keratinizing tumors, followed by large cell nonkeratinizing and small cell nonkeratinizing types. Moreover, elevation of SCC Ag was statistically significant (p < 0.001) among all the three histologic subtypes compared to controls. However, SCC Ag levels were not consistently correlated to the stage of the disease. Patients with pretherapeutic SCC Ag levels above 30 ng/ml had a faster recurrence rate and shorter survival than those who exhibited antigen values below 2.0 ng/ml. From our results, it is suggested that SCC Ag has limited use as a parameter for early diagnosis of cervical carcinoma, but it seems to reflect advancement of the disease. These findings indicate that SCC Ag elevation may prove to be a valuable marker in predicting subclinical disease.

Abstract
Circulating prolactin, CA 15–3 and TPA were assayed pre-therapeutically and sequentially thereafter from 68 breast cancer patients attending the Gujarat Cancer and Research Institute, Ahmedabad — a regional cancer institute in Western India. The three marker values were correlated with the stage, histologic grade and disease status. At least one of the markers was elevated in 82% of patients. CA 15–3 and TPA levels were elevated with the advancement of stage. Prolactin levels were high in poorly differentiated tumors of pre-menopausal patients. The disease status was effectively reflected by the levels of prolactin and CA 15–3. TPA showed high false positivity so was of no use as an indicator of disease status. Recurrence could be predicted early, with a lead time of 3–6 months using prolactin and CA 15–3.

Abstract
The purpose of this study was to examine the association of telomerase activity with clinical and histopathological prognostic variables in primary breast cancer (n=64). Telomerase activity in breast cancer was also compared with that in benign (n=10) and non-malignant tissues (n=8; post-lumpectomy tissues histopathologically defined as containing no residual tumor). The parameter was assessed using the Telomerase PCR ELISA kit. Values above OD 0.120 were considered positive. Estrogen and progesterone receptors (ER and PgR) were assayed by the dextran-coated charcoal method and levels >10 fmol/mg cytosol protein were taken as positive. Telomerase activity was detected in 20% and 50% of the patients with benign lesions and primary breast cancer, respectively, and in 50% of post-lumpectomy breast tissues histopathologically defined as containing no residual tumor. Telomerase activity was present in all stages of breast carcinoma and showed a significant inverse correlation with lymph node status (p=0.006), lymphatic invasion (p=0.035) and necrosis (p=0.033). Moreover, when stage II patients were grouped according to nodal involvement, a trend towards significance was observed (p=0.055). No correlation was observed with ER and PgR. The results of our study suggest that telomerase activity might be associated with the presence of cancer cells. Furthermore, telomerase activation may occur early in breast cancer and may be periodically downregulated during subsequent tumor progression.

Abstract
Background: Ultrasound has become an increasingly utilized tool for the imaging of the musculoskeletal system, especially for imaging the components of the knee. Even though MRI is touted as being the golden standard for identifying knee pathologies, the use of ultrasound has gained popularity in this field given its ability for rapid diagnosis. This study aims to investigate the efficacy of point-of-care ultrasound (POCUS) to diagnose injuries to the medial knee compartment when compared to magnetic resonance imaging (MRI). Methods: This was a prospective, observational study conducted at an orthopedic outpatient clinic. Prospective patients with medial knee pain scheduled for an MRI of the knee were evaluated by POCUS prior to the MRI. Sonographic findings were then compared to MRI results to assess correlation. Results: Nine patients were enrolled in the study. Median age was 53 years and eight were male (89%). POCUS demonstrated 100% sensitivity and 50% specificity for medial meniscus tear and 67% sensitivity and 83% specificity for medial collateral ligament (MCL) tear. Conclusion: Ultrasound may have a role as the initial rapid imaging modality in patients with suspected medial meniscus or MCL tears as it is highly sensitive, and it may serve as an effective screening tool for patients with both acute and chronic knee pain.

Abstract
Background & objectives: Anthrax caused by Bacillus anthracis is primarily a disease of herbivorous animals, although several mammals are vulnerable to it. ELISA is the most widely accepted serodiagnostic assay for large scale surveillance of cutaneous anthrax. The aims of this study were to develop and evaluate a quantitative ELISA for determination of IgG antibodies against B. anthracis protective antigen (PA) in human cutaneous anthrax cases. Methods: Quantitative ELISA was developed using the recombinant PA for coating and standard reference serum AVR801 for quantification. A total of 116 human test and control serum samples were used in the study. The assay was evaluated for its precision, accuracy and linearity. Results: The minimum detection limit and lower limit of quantification of the assay for anti-PA IgG were 3.2 and 4 µg/ml, respectively. The serum samples collected from the anthrax infected patients were found to have anti-PA IgG concentrations of 5.2 to 166.3 µg/ml. The intra-assay precision per cent CV within an assay and within an operator ranged from 0.99 to 7.4 per cent and 1.7 to 3.9 per cent, respectively. The accuracy of the assay was high with a per cent error of 6.5 - 24.1 per cent. The described assay was found to be linear between the range of 4 to 80 ng/ml (R2=0.9982; slope=0.9186; intercept = 0.1108). Interpretation & conclusions: The results suggested that the developed assay could be a useful tool for quantification of anti-PA IgG response in human after anthrax infection or vaccination.

Abstract
The spatial and the angular variants of the Imbert-Federov (IF) beam shifts and the angular Goos-Hänchen (GH) shift contribute in a complex interrelated way to the resultant beam shift in partial reflection at planar dielectric interfaces. Here, we show that the two variants of the IF effects can be decoupled and separately observed by weak value amplification and subsequent conversion of spatial ↔angular nature of the beam shifts using appropriate pre and post selection of polarization states. Such optimized weak measurement schemes also enable one to nullify one effect (either the GH or the IF) and exclusively observe the other. We experimentally demonstrate this and illustrate various other intriguing manifestations of optimized weak measurements in elliptical and / or linear polarization basis. We also present a Poincare sphere based analysis on conversion / retention of the angular or spatial nature of the shifts with pre and post selection of states in weak measurement. The demonstrated ability to amplify, controllably decouple or combine the beam shifts via weak measurements may prove to be valuable for understanding the different physical contributions of the effects and for their applications in sensing and precision metrology.

Abstract
The optical analogue of quantum weak measurements has shown considerable promise for the amplification and observation of tiny optical beam shifts, namely Goos-Hänchen (GH) and Imbert-Fedorov (IF) shifts. Here, we demonstrate simultaneous weak value amplification of both the angular GH and the IF shifts in partial reflection of a fundamental Gaussian beam at planar dielectric interfaces. We employ pre and postselection schemes with appropriate linear polarization basis states for simultaneous weak measurements and amplification of both of these shifts. The experimentally observed enhancement of the beam shifts and their dependence on the angle of incidence are analyzed/interpreted via theoretical treatment of weak measurements.

Abstract
Non-invasive criteria determining the progress of brain healing are especially important in aging, providing a case-specific therapeutic strategy in populations with dysregulated neurorepair mechanisms. We hypothesized that temporal evolution of magnetic resonance imaging (MRI) of T2 tissue relaxation values correlate with neurological severity scores (NS), and provide a robust indicator of healing in the aging brain after stroke. Pre-treatment of aged rats with brain-only proton irradiation was undertaken to pre-condition the inflammatory system. Irradiation was performed 10days prior to right middle cerebral artery occlusion (MCAO) for 50min (MCAO+Rad). Control rats included naïve (no ischemia, no radiation), irradiated-only (Rad), irradiated ischemic, or ischemic-only (MCAO). MRI and NS were obtained at 3, 14 and 28days post-stroke. At 28days post-stroke, immunofluorescence for visualizing blood vessels (Von Willebrand factor; vWF), neurons (neuronal nuclear antigen; NeuN), astrocytes (glial fibrillary acidic protein; GFAP), activated microglia/macrophages (ionized calcium-binding adapter molecule 1, Iba1), T-lymphocytes (CD3), phagocytes (ED1) and apoptotic cells (caspase-3) was assessed. We found a positive T2-NS correlation in irradiated, ischemic rats that corresponded to late-stage brain recovery. Late-stage brain recovery was characterized by improved neovascularization, formation of glio-vascular complexes (visualized by GFAP/vWF) and enhanced neuronal viability (by NeuN/caspase-3) in the peri-lesional zone. The immune response plateaued at the late stage of repair as evidenced by significantly decreased expression (41.7%) and distribution of phagocytes (phagocytic rim decreased 44.6%). We also found reduced infiltration of T-lymphocytes (CD3) in the brain and normalization of blood lymphocytes. The observed T2-NS correlations may provide a simple MRI-based criterion for recognition of regenerative brain transformation in aged patients following stroke. Selective activation of innate immunity and accelerated transition from pro-inflammatory to pro-healing macrophage phenotypes induced by localized brain irradiation is a potential mechanism for enhancing repair ability in the elderly.

Abstract
The longitudinal and transverse beam shifts, namely, the Goos-Hänchen (GH) and the Spin-Hall (SH) shifts are usually observed at planar interfaces. It has recently been shown that the transverse SH shift may also arise due to scattering of plane waves. Here, we show that analogous in-plane (longitudinal) shifts also exist in the scattering of plane waves from micro/nano systems. We study both the GH and the SH shifts in plasmonic metal nanoparticles/nanostructures and dielectric micro-particles employing a unified framework that utilizes the transverse components of the Poynting vector of the scattered wave. The results demonstrate that the interference of neighboring resonance modes in plasmonic nanostructures (e.g., electric dipolar and quadrupolar modes in metal spheres) leads to great enhancement of the GH shift in scattering from such systems. We also unravel interesting correlations between these shifts with the polarimetry parameters, diattenuation and retardance.

Abstract
Despite recent controversies about toxicity and reduced efficacy, vancomycin remains the current treatment of choice for methicillin-resistant Staphylococcus aureus (MRSA) bacteraemia. The parameter associated with treatment success is the vancomycin 24-h area under concentration-time curve to MIC ratio (AUC0-24/MIC). We aimed to determine the utility of calculated AUCs and explore the optimal AUC0-24/MIC targets associated with treatment success. In this single-centre retrospective observational cohort study of 127 patients with MRSA bacteraemia, forty-five (35.4%) did not respond to vancomycin treatment. Patient characteristics were essentially the same between those who did not respond to vancomycin treatment and those with treatment success, with independent predictors of treatment failure being source of bacteraemia (odds ratio (OR), 4.29; 95% confidence interval (CI), 1.50-12.26; p 0.007) and not achieving an AUC0-24/MICBMD (using broth microdilution) target of ≥398 (OR, 11.4; 95% CI, 4.57-28.46; p< 0.001). Bacteraemic source-specific thresholds were observed with a higher AUC0-24/MICBMD target of 440 required for high-risk sources (e.g. infective endocarditis) compared with 330 for low-risk sources (line related bacteraemia). Overall treatment success in patients with MRSA bacteraemia was associated with a vancomycin AUC0-24/MICBMD target of ≥398, with source-specific targets observed. Future vancomycin practice guidelines will need to take into account MIC methodology, source of bacteraemia and patient populations prior to setting targets and monitoring recommendations.

Abstract
Quantitative fluorescence spectroscopic Mueller matrix measurements from the connective tissue regions of human cervical tissue reveal intriguing fluorescence diattenuation and polarizance effects. Interestingly, the estimated fluorescence linear diattenuation and polarizance parameters were considerably reduced in the precancerous tissues as compared to the normal ones. These polarimetry effects of the autofluorescence were found to originate from anisotropically organized collagen molecular structures present in the connective tissues. Consequently, the reduction of the magnitude of these polarimetric parameters at higher grades of precancer was attributed to the loss of anisotropic organization of collagen, which was also confirmed by control experiments. These results indicate that fluorescence spectral diattenuation and polarizance parameters may serve as potentially useful diagnostic metrics.

Abstract
The spin orbit interactions (SOI) of light mediated by single scattering from plasmon resonant metal nanoparticles (nanorods and nanospheres) are investigated using Jones and Mueller matrix polarimetry formalism. The effect of neighboring resonances in plasmonic nanostructures (e.g., orthogonal electric dipolar modes in rods or electric dipolar and quadrupolar modes in spheres) on the individual SOI effects are analyzed and interpreted via the Mueller matrix-derived polarimetry characteristics, namely, diattenuation d and retardance δ. The results clearly reveal that each of these can be controllably tuned and enhanced by exploiting the interference of neighboring modes.

Abstract
Schwannomas are benign tumours that arise from the Schwann cells of nerve fibres. They commonly occur in the head and neck, mediastinum and extremities. They are extremely rare in the pelvis. These are usually slow-growing tumours and are often detected incidentally. Preoperative diagnosis is extremely difficult as there are no definitive signs on imaging. Aspiration biopsy is often inconclusive or misleading. Surgical excision is both diagnostic and therapeutic. As these tumours are often large in size, open excision is most commonly performed. We describe a case of a large, cystic schwannoma of the pelvis causing bladder outlet obstruction and bilateral hydroureteronephrosis. Complete surgical excision was performed laparoscopically.

Abstract
Antioxidative stress response of free-floating aquatic fern (Salvinia natans Linn.) was studied under increasing toxic amount of aluminium (Al) and its modulation by exogenous application of polymaine. Increased levels of superoxide (O2 (-)) and hydrogen peroxide (H2O2) species from affected tissues suggested that plants were undergoing oxidative stress and it was concominant with increased accumulation of Al in a dose dependent manner. Application of polyamine like putrescine (Put) led to a decrease in oxidative stress as revealed by reduced level of O2 (-) and H2O2. Al toxicity resulted into decreased biomass that was ameliorated by the application of Put. The changes observed in lipid peroxidation (MDA) and protein oxidation also indicated that plats are undergoing Al induced oxidative stress. In order to circumvent the oxidative stress resulting from Al toxicity, plants enzymatic and nonenzymatic antioxidant pathways were active. The ratio of both oxidized and reduced cellular glutathione exhibited significant variation in response to Al stress and was improved upon Put treatment. Peroxidase and glutathione were upregulated whereas catalse was downregulated under varying doses of Al. Isozyme profile of above enzymes also showed a trend with increasing amount of Al. The nuclear disintegration study using comet assay was indicative of Al induced oxidative stress. In the present study, we have explored the antioxidative response of aquatic fern Salvinia natans Linn in response to Al toxicity. The application of polyamine Put improved the overall antioxidative response and thus would make it a better candidate to be used as hyper accumulator of Al and other toxic metals.

Abstract
Self-mutilation of genitalia is an extremely rare entity, usually found in psychotic patients. Klingsor syndrome is a condition in which such an act is based upon religious delusions. The extent of genital mutilation can vary from superficial cuts to partial or total amputation of penis to total emasculation. The management of these patients is challenging. The aim of the treatment is restoration of the genital functionality. Microvascular reanastomosis of the phallus is ideal but it is often not possible due to the delay in seeking medical attention, non viability of the excised phallus or lack of surgical expertise. Hence, it is not unusual for these patients to end up with complete loss of the phallus and a perineal urethrostomy. We describe a patient with Klingsor syndrome who presented to us with near total penile amputation. The excised phallus was not viable and could not be used. The patient was managed with surgical reconstruction of the penile stump which was covered with loco-regional flaps. The case highlights that a functional penile reconstruction is possible in such patients even when microvascular reanastomosis is not feasible. This technique should be attempted before embarking upon perineal urethrostomy.

Abstract
Bacillus anthracis, the causative agent of anthrax is one of the most important biological warfare agents. In this study, surface plasmon resonance (SPR) technology was used for indirect detection of B. anthracis by detecting protective antigen (PA), a common toxin produced by all live B. anthracis bacteria. For development of biosensor, a monoclonal antibody raised against B. anthracis PA was immobilized on carboxymethyldextran modified gold chip and its interaction with PA was characterized in situ by SPR and electrochemical impedance spectroscopy. By using kinetic evaluation software, KD (equilibrium constant) and Bmax (maximum binding capacity of analyte) were found to be 20 fM and 18.74, respectively. The change in Gibb's free energy (∆G = -78.04 kJ/mol) confirmed the spontaneous interaction between antigen and antibody. The assay could detect 12 fM purified PA. When anthrax spores spiked soil samples were enriched, PA produced in the sample containing even a single spore of B. anthracis could be detected by SPR. PA being produced only by the vegetative cells of B. anthracis, confirms indirectly the presence of B. anthracis in the samples. The proposed method can be a very useful tool for screening and confirmation of anthrax suspected environmental samples during a bio-warfare like situation.

Abstract
The rice varieties viz. Nonabokra and Swarna were evaluated on the basis of their responses for oxidative stress induced by sodium chloride (NaCl) and the effects of exogenously applied polyamine thereon. Rice seedlings were treated with 200 mM of NaCl supplemented with two dosages: 1 mM and 2 mM putrescine. Following treatments, plants were evaluated for accumulation of reactive oxygen species (ROS) like O2 (-), H2O2 etc. in tissues, lipid peroxidation, protein carbonylation, accumulation of flavonoids and anthocyanin, activities of different oxidative enzymes like guaiacol peroxidase (GPX), catalase (CAT) and glutathione reductase (GR). Preliminary, oxidative stress out of salinity was ensured by plants from significantly higher accumulation of O2 (-) and H2O2 in the tissues of the NaCl treated varieties. Irrespective of varieties, there recorded a significant variation of the endogenous polyamine profiles under NaCl stress. Interestingly, exogenous application of putrescine had a close relationship on O2 (-) and H2O2 content for both the varieties. However, Nonabokra was evident as more respondent than Swarna to applied putrescine. The other effects of oxidative stress was impacted on plants as higher values of MDA content, enhanced rate of protein oxidation and putrescine recorded as an alleviating agent regardless of varieties with dose dependant manner. The generation of ROS and cellular disintegration was accompanied by up regulation of non-enzymatic and enzymatic antioxidation pathways with exogenous application of putrescine. For non-enzymatic antioxidant, it revealed that putrescine was highly effective for sustaining the anthocyanin and flavonoid content in both the varieties under salinity. Whereas, antioxidative enzyme, CAT showed its diminished activity; but activity of GPX and GR were significantly induced under salinity and it was according to the concentration of applied putrescine.
