Translation and Validation of Hindi Version of Adolescent Peer Relation Instrument for Bullying Victimization.

OBJECTIVES: To translate and validate Hindi version of Adolescent Peer Relation Instrument (APRI) and to evaluate burden of bullying victimization among school-going adolescents. METHODS: A school-based cross-sectional study was performed from July 2021 to June 2022 on 9th-12thclass students. Adolescent peer relation instrument was used to evaluate bullying victimization. Reliability and validity of tool, prevalence and strength of association was analyzed by appropriate statistical methods. RESULTS: Bullying and victimization were present in 70.8% and 62.9% adolescents, respectively. Total bullying was significantly less in students <16 years of age (OR 0.995, 95% CI 0.483, 2.049) and those with less than three friends (OR 0.816, 95% CI 0.482, 1.383). Total bullying and total victimization was significantly more in boys (OR 1.993, 95% CI 1.281, 3.099 for bullying and OR 1.584, 95% CI 1.047, 2.397 for victimization). Cronbach's alpha for bullying and victimization was 0.89 and 0.897, respectively. Convergent validity between items of different subscales of bullying and victimization was observed (r value > 0.7) except for social bullying and social victimization. There was weak correlation between subscales of bullying and victimization suggestive of discriminant validity (r value < 0.4). CONCLUSIONS: The Hindi version of APRI has a good reliability and construct validity. About three-fourths and two-thirds of adolescents were involved in bullying and victimization, respectively, with a few identified risk factors. Special counselling sessions at schools must be implemented for children involved in bullying.

TROPHY-U-01, a phase II open-label study of sacituzumab govitecan in patients with metastatic urothelial carcinoma progressing after platinum-based chemotherapy and checkpoint inhibitors: updated safety and efficacy outcomes.

BACKGROUND: Sacituzumab govitecan (SG) is a Trop-2-directed antibody-drug conjugate containing cytotoxic SN-38, the active metabolite of irinotecan. SG received accelerated US Food and Drug Administration approval for locally advanced (LA) or metastatic urothelial carcinoma (mUC) previously treated with platinum-based chemotherapy and a checkpoint inhibitor, based on cohort 1 of the TROPHY-U-01 study. Mutations in the uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) gene are associated with increased adverse events (AEs) with irinotecan-based therapies. Whether UGT1A1 status could impact SG toxicity and efficacy remains unclear. PATIENTS AND METHODS: TROPHY-U-01 (NCT03547973) is a multicohort, open-label, phase II registrational study. Cohort 1 includes patients with LA or mUC who progressed after platinum- and checkpoint inhibitor-based therapies. SG was administered at 10 mg/kg intravenously on days 1 and 8 of 21-day cycles. The primary endpoint was objective response rate (ORR) per central review; secondary endpoints included progression-free survival, overall survival, and safety. Post hoc safety analyses were exploratory with descriptive statistics. Updated analyses include longer follow-up. RESULTS: Cohort 1 included 113 patients. At a median follow-up of 10.5 months, ORR was 28% (95% CI 20.2% to 37.6%). Median progression-free survival and overall survival were 5.4 months (95% CI 3.5-6.9 months) and 10.9 months (95% CI 8.9-13.8 months), respectively. Occurrence of grade ≥3 treatment-related AEs and treatment-related discontinuation were consistent with prior reports. UGT1A1 status was wildtype (∗1|∗1) in 40%, heterozygous (∗1|∗28) in 42%, homozygous (∗28|∗28) in 12%, and missing in 6% of patients. In patients with ∗1|∗1, ∗1|∗28, and ∗28|∗28 genotypes, any grade treatment-related AEs occurred in 93%, 94%, and 100% of patients, respectively, and were managed similarly regardless of UGT1A1 status. CONCLUSIONS: With longer follow-up, the ORR remains high in patients with heavily pretreated LA or mUC. Safety data were consistent with the known SG toxicity profile. AE incidence varied across UGT1A1 subgroups; however, discontinuation rates remained relatively low for all groups.

Recommended Resting-State fMRI Acquisition and Preprocessing Steps for Preoperative Mapping of Language and Motor and Visual Areas in Adult and Pediatric Patients with Brain Tumors and Epilepsy.

Resting-state (rs) fMRI has been shown to be useful for preoperative mapping of functional areas in patients with brain tumors and epilepsy. However, its lack of standardization limits its widespread use and hinders multicenter collaboration. The American Society of Functional Neuroradiology, American Society of Pediatric Neuroradiology, and the American Society of Neuroradiology Functional and Diffusion MR Imaging Study Group recommend specific rs-fMRI acquisition approaches and preprocessing steps that will further support rs-fMRI for future clinical use. A task force with expertise in fMRI from multiple institutions provided recommendations on the rs-fMRI steps needed for mapping of language, motor, and visual areas in adult and pediatric patients with brain tumor and epilepsy. These were based on an extensive literature review and expert consensus.Following rs-fMRI acquisition parameters are recommended: minimum 6-minute acquisition time; scan with eyes open with fixation; obtain rs-fMRI before both task-based fMRI and contrast administration; temporal resolution of ≤2 seconds; scanner field strength of 3T or higher. The following rs-fMRI preprocessing steps and parameters are recommended: motion correction (seed-based correlation analysis [SBC], independent component analysis [ICA]); despiking (SBC); volume censoring (SBC, ICA); nuisance regression of CSF and white matter signals (SBC); head motion regression (SBC, ICA); bandpass filtering (SBC, ICA); and spatial smoothing with a kernel size that is twice the effective voxel size (SBC, ICA).The consensus recommendations put forth for rs-fMRI acquisition and preprocessing steps will aid in standardization of practice and guide rs-fMRI program development across institutions. Standardized rs-fMRI protocols and processing pipelines are essential for multicenter trials and to implement rs-fMRI as part of standard clinical practice.

Fetal cardiovascular changes during open and fetoscopic in-utero spina bifida closure.

OBJECTIVE: Laparotomy-assisted fetoscopic closure of spina bifida utilizing heated-humidified carbon dioxide gas has been associated with less maternal morbidity than open in-utero spina bifida closure. Fetal cardiovascular changes during these surgical interventions are not well defined. Our objective was to compare fetal bradycardia (defined as fetal heart rate (FHR)<110 bpm over 10 minutes) and changes in umbilical artery Doppler parameters throughout open in-utero closure with those observed during laparotomy-assisted fetoscopic closure. METHODS: We conducted a prospective cohort study of 22 open and 46 fetoscopic consecutive in-utero closures between 2019 and 2023. Both cohorts had similar preoperative counseling and clinical management. FHR and umbilical artery velocimetry were systematically obtained during preoperative assessment, every 5 minutes during the intraoperative period, and in the postoperative assessment. FHR, pulsatility indexes and end-diastolic flows were segmented into hourly periods during surgery, and the lowest values were averaged for analysis. Umbilical vein maximum velocities were measured in the fetoscopic cohort. Each fetal heart rate recording time point was correlated to maternal parameters, including heart rate, systolic and diastolic blood pressures. RESULTS: Fetal bradycardia occurred in 4/22 cases (18.2%) of open in-utero closure and in 21/46 cases (45.7%) of fetoscopic closure. FHR gradually decreased in both cohorts after general anesthesia and decreased further during surgery. FHR were significantly lower after two hours of surgery in the fetoscopic closure than in the open in-utero closure group. In addition, the FHR (BPM) change in the final stages of the fetal surgery from the baseline FHR was significantly lower in the fetoscopic cohort (-32.3 (-35.7, -29.1)) compared to the open cohort (-23.5 (-28.1, -18.8)) (p=0.002). Abnormal end-diastolic flow (defined as absent or reversed end-diastolic flow) in the umbilical artery Doppler velocity occurred in 3/22 (13.6%) of the open closure cohort and in 23/46 (50%) of the fetoscopic closure cohort (p=0.004). There were no differences in umbilical artery end-diastolic flow and pulsatility index between closure techniques during the various stages of assessment. CONCLUSIONS: We observed a decrease in the FHR and abnormalities in umbilical artery Doppler parameters in both open in-utero and fetoscopic closure groups. Fetal bradycardia was more prominent during fetoscopic closure following heated-humidified carbon dioxide insufflation, but the FHR recovered after cessation of the heated-humidified carbon dioxide. Changes in FHR and umbilical artery Doppler parameters during in-utero spina bifida closure were observed to be transient, no cases required emergency delivery and no fetoscopic closure were converted to open closure. These observations should inform algorithms for perioperative management of fetal bradycardia associated with in-utero spina bifida closure. This article is protected by copyright.

Nicotine promotes epithelial to mesenchymal transition and gemcitabine resistance via hENT1/RRM1 signalling in pancreatic cancer and chemosensitizing effects of Embelin-a naturally occurring benzoquinone.

Pancreatic cancer is lethal due to poor prognosis with 5-year survival rate lesser than 5 %. Gemcitabine is currently used to treat pancreatic cancer and development of chemoresistance is a major obstacle to overcome pancreatic cancer. Nicotine is a known inducer of drug resistance in pancreatic tumor micro-environment. Present study evaluates chemoresistance triggered by nicotine while treating with gemcitabine and chemosensitization using Embelin. Embelin is a naturally occurring benzoquinone from Embelia ribes possessing therapeutic potency. To develop nicotine-induced chemo-resistance, pancreatic cancer cells PANC-1 and MIA PaCa-2 were continuously treated with nicotine followed by exposure to gemcitabine. Gemcitabine sensitivity assay and immunoblotting was performed to assess the chemo-resistance. Antiproliferative assays such as migration assay, clonogenic assay, Mitochondrial Membrane Potential (MMP) assay, dual staining assay, comet assay, Reactive Oxygen Species (ROS) assay, cell cycle analysis and immunoblotting assays were performed to witness the protein expression involved in chemoresistance and chemosensitization. Epithelial to mesenchymal transition was observed in nicotine induced chemoresistant cells. Gemcitabine sensitivity assay revealed that relative resistance was increased to 6.26 (p < 0.0001) and 6.45 (p < 0.0001) folds in resistant PANC-1 and MIA PaCa-2 compared to parental cells. Protein expression studies confirmed resistance markers like hENT1 and dCK were downregulated with subsequent increase in RRM1 expression in resistant cells. Embelin considerably decreased the cell viability with an IC50 value of 4.03 ± 0.08 µM in resistant PANC-1 and 2.11 ± 0.04 µM in resistant MIA PaCa-2. Cell cycle analysis showed Embelin treatment caused cell cycle arrest at S phase in resistant PANC-1 cells; in resistant MIA PaCa-2 cells there was an escalation in the Sub G1. Embelin upregulated Bax, γH2AX, p53, ERK1/2 and hENT1 expression with concomitant down regulation of Bcl-2 and RRM1. Bioactive molecule embelin, its combination with gemcitabine could provide new vistas to overcome chemo resistance in pancreatic cancer.

Tetrahydrobenzothiophene derivatives ameliorate Mia PaCa-2 cell progression and induces apoptosis via inhibiting EGFR2 tyrosine kinase signal.

A series of new thiophene analogues with acarbonitrile-basedmoiety were designed and synthesized via structural optimization. The conjugates were assessed for their in-vitro cytotoxic activity against a human pancreatic cancer cell line (Mia PaCa-2) and among them compound 5b showed IC50 value of 13.37 ± 2.37 µM. The compounds 5b (20 µM & 25 µM) and 7c (30 & 35 µM) also showed reduced clonogenicity, enhanced ROS and decreased mitochondrial membrane potential in Mia PaCa-2 cells. Treatment with these compounds also increased apoptotic population as evident with the double staining assay. Among the evaluated series, compounds 5b, 5g, 7c, and 9a attained a greater inhibitory potency than first generation's reversible EGFR inhibitor, Gefitinib. EGFR2 enzyme inhibitory studies revealed that 5b efficiently and arbitrarily suppressed the development of EGFR2 dependent cells and inhibited the enzymatic activity with an IC50 value of 0.68 µM; interestingly, the most effective molecule 5b with N-methyl piperazine substitution, has 1.29-fold greater potency than well-known EGFR inhibitor Gefitinib and increased Gefitinib's anti-growth impact with 2.04 folds greater against Mia PaCa-2. The in-vitro studies were validated with in-silico docking studies wherein compounds 5b and 7c exhibited binding energies of -8.2 and -7.4 Kcal/mol respectively. The present study reveals that tetrahydrobenzothiophene based analogues could be a promising lead for the evolution of potent chemo preventives over pancreatic cancer.

CLINICAL AND OBJECTIVE TEST CHARACTERISTICS OF VESTIBULAR MIGRAINE: IMPLICATIONS FOR DIAGNOSIS AND MANAGEMENT.

The research we provided look at a number of factors, such as age, unilateral testing, and squinting both during the ictal and interictal periods to define vestibular migraine. One hundred and ten adults with recurrent spontaneous and positional vertigo participated in the study, which the investigators did. Vestibular migraines (VM) or probable vestibular migraine constituted the two diagnoses given to the patients (n = 29 and n = 76, respectively). The findings revealed those surveyed frequently complained of headache (85.3%), spinning vertigo (76.2%), and Mal de Débarquement (60.2%), with movement hypersensitivity (32.6%). After an episode, 75.2% of individuals having vestibular migraine showed spontaneous squinting, whereas 16.5% did so among assaults, although fixing was forbidden. 27.3% of people had clear spatial squinting after an assault, while 57.3% did so after assaults. In 51.2% of instances, the direction of ictal spontaneous Nystagmus was straight, while in 19.5% of cases, it was vertical. Positional and spontaneously ictal squinting was evaluated at speeds between 0.0 and 59.3 degrees per second and 0.0 and 99.9 levels per minute, respectively. In 92.6% and 25.1% of instances, respectively, the interact spontaneous and positional nystagmus velocities were typically less than 3 degrees/second. When contrasted with the time within assaults, squinting speeds were substantially greater after an assault. According to additional tests, 98.6% of those tested exhibited normal lateral video head impulse test gains, indicating that their vestibule-ocular responses were in place. The calorie test findings were symmetrical in 86.4% of the instances, showing normal vestibular function. In 90.4% and 95.2% of cases misogynic potentials displayed symmetrical magnitudes. In 69.8% and 98.1% of instances, misogynic possibilities were identical. In 89.3% of cases, the audiometer data is generally uniform and age-consistent. In outcome, low-velocity squinting that can be horizontal, vertical, or torsional motions occur throughout a sensory migraines event. The investigation also discovered that patients with vestibular migraine often had acceptable audio vestibular test findings.

Long-Term Follow-up of Multinodular and Vacuolating Neuronal Tumors and Implications for Surveillance Imaging.

BACKGROUND AND PURPOSE: Most multinodular and vacuolating neuronal tumors (MVNTs) are diagnosed and followed radiologically without any change across time. There are no surveillance guidelines or quantitative volumetric assessments of these tumors. We evaluated MVNT volumes during long follow-up periods using segmentation tools with the aim of quantitative assessment. MATERIALS AND METHODS: All patients with MVNTs in a brain MR imaging report in our system were reviewed. Patients with only 1 brain MR imaging or in whom MVNT was not clearly the most likely diagnosis were excluded. All MVNTs were manually segmented. For all follow-up examinations, absolute and percentage volume change from immediately prior and initial examinations were calculated. RESULTS: Forty-eight patients (32 women; median age, 50.5 years at first scanning) underwent 158 brain MRIs. The median duration between the first and last scan was 15.6 months (interquartile range, 5.7-29.6 months; maximum, 6.4 years) and between consecutive scans, it was 6.7 months (interquartile range, 3.3-12.4 months; maximum, 4.9 years). Pearson correlation coefficients between days since immediately prior scan versus absolute and percentage volume change from immediately prior scan were r = 0.05 (P = .60) and r = 0.07 (P = .45), respectively. For the relationship between days since the first scan versus absolute and percentage volume change from the first scan, values were r = -0.06 (P = .53) and r = -0.04 (P = .67), respectively. CONCLUSIONS: MVNT segmentation across follow-up brain MR imaging examinations did not demonstrate significant volume differences, suggesting that these tumors do not enlarge with time. Hence, frequent surveillance imaging of newly diagnosed MVNTs may not be necessary.

Microsecond Isomer at the N=20 Island of Shape Inversion Observed at FRIB.

Excited-state spectroscopy from the first experiment at the Facility for Rare Isotope Beams (FRIB) is reported. A 24(2)-µs isomer was observed with the FRIB Decay Station initiator (FDSi) through a cascade of 224- and 401-keV γ rays in coincidence with ^{32}Na nuclei. This is the only known microsecond isomer (1 µs≤T_{1/2}<1 ms) in the region. This nucleus is at the heart of the N=20 island of shape inversion and is at the crossroads of the spherical shell-model, deformed shell-model, and ab initio theories. It can be represented as the coupling of a proton hole and neutron particle to ^{32}Mg, ^{32}Mg+π^{-1}+ν^{+1}. This odd-odd coupling and isomer formation provides a sensitive measure of the underlying shape degrees of freedom of ^{32}Mg, where the onset of spherical-to-deformed shape inversion begins with a low-lying deformed 2^{+} state at 885 keV and a low-lying shape-coexisting 0_{2}^{+} state at 1058 keV. We suggest two possible explanations for the 625-keV isomer in ^{32}Na: a 6^{-} spherical shape isomer that decays by E2 or a 0^{+} deformed spin isomer that decays by M2. The present results and calculations are most consistent with the latter, indicating that the low-lying states are dominated by deformation.

Trends in clinical validation and usage of US Food and Drug Administration-cleared artificial intelligence algorithms for medical imaging.

AIM: To examine the current landscape of US Food and Drug Administration (FDA)-approved artificial intelligence (AI) medical imaging devices and identify trends in clinical validation strategy. MATERIALS AND METHODS: A retrospective study was conducted that analysed data extracted from the American College of Radiology (ACR) Data Science Institute AI Central database as of November 2021 to identify trends in FDA clearance of AI products related to medical imaging. Product and clinical validation information of each device was gathered from their respective public 510(k) summary or de novo request submission, depending on their type of authorisation. RESULTS: Overall, the database included a total of 151 AI algorithms that were cleared by the FDA between 2008 and November 2021. Out of the 151 FDA summaries reviewed, 97 (64.2%) reported the use of clinical data to validate their device, with six (4%) revealing study participant demographics, and eight (5.3%) reporting the specifications of the machines used. A total of 51 (33.8%) AI devices characterised their clinical data as multicentre, three (2%) as single-centre, and the remaining 97 (64.2%) did not specify. The ground truth used for clinical validation was specified in 78 (51.6%) FDA summaries. CONCLUSION: A wide breadth of AI algorithms has been developed for medical imaging. Most of the FDA summaries of the devices mention their use of clinical data and patient cases for device validation; however, few devices revealed the patient demographics or machine specifications used in their clinical studies, which may lead some consumers to question their external validation.

Crossing N=28 Toward the Neutron Drip Line: First Measurement of Half-Lives at FRIB.

New half-lives for exotic isotopes approaching the neutron drip-line in the vicinity of N∼28 for Z=12-15 were measured at the Facility for Rare Isotope Beams (FRIB) with the FRIB decay station initiator. The first experimental results are compared to the latest quasiparticle random phase approximation and shell-model calculations. Overall, the measured half-lives are consistent with the available theoretical descriptions and suggest a well-developed region of deformation below ^{48}Ca in the N=28 isotones. The erosion of the Z=14 subshell closure in Si is experimentally confirmed at N=28, and a reduction in the ^{38}Mg half-life is observed as compared with its isotopic neighbors, which does not seem to be predicted well based on the decay energy and deformation trends. This highlights the need for both additional data in this very exotic region, and for more advanced theoretical efforts.

Prediction and Prevention of Gestational Diabetes Mellitus and Its Sequelae by Administering Metformin in the Early Weeks of Pregnancy.

Diabetes mellitus in recent years has become a relentlessly evolving pandemic. Measures for the screening and early detection of diabetes are practiced all around the world. However, considering the ever-increasing magnitude of the problem, the present efforts should especially focus on the primordial prevention of diabetes. A ray of hope for preventing the development of diabetes in an individual arises from the concept that many adult-onset diseases have already been programmed while the individual was still in-utero. In women with hyperglycemia-in-pregnancy, maternal hyperglycemia results in fetal hyperinsulinemia, which leads to increased adiposity in the fetus, and insulin resistance and diabetes in adulthood. We have ventured to point out that the fetal beta-cells start secreting insulin at 10-11 weeks of pregnancy and fetal hyperinsulinemia persists with maternal hyperglycemia, in a pregnant woman who would develop gestational diabetes. Considering the fetal glucose-steal phenomenon and the fetal renal threshold for glucose, we have suggested a two-hour post-prandial blood-glucose (PPBG) value of >110 mg/dL as the cut-off for the prediction of gestational diabetes in the early weeks of pregnancy. Furthermore, we have emphasized the use of metformin in addition to medical nutrition therapy in the early weeks to maintain PPBG around 110 mg/dL to prevent gestational diabetes. In this paper, we recommend early, universal screening of all pregnant women during the early weeks of the first trimester and put forward that a two-hour PPBG of >110 mg/dl during the 8th-10th week of pregnancy would predict the risk of gestational diabetes in the pregnant woman. We suggest early testing and intervention to prevent the development of fetal hyperinsulinemia as a primordial prevention approach for diabetes.

Spatial Relationship of Maxillary Posterior Teeth with Maxillary Sinus Floor in Sagittal, Coronal and Axial Planes by Using Cone-Beam Computed Tomography in a Subpopulation of Central India.

Inadvertent perforation of the root apex during endodontic procedure in maxillary posterior teeth may unnecessarily invite the complications of sinusitis or inflammatory responses. This becomes even more important when performing endodontic surgical procedures. Thus, it is mandatory to have the precise knowledge of anatomic structures which are in close proximity to the apex of roots and its variations among different geographic area. This retrospective observational study was performed in the Central India to assess the spatial relationships between the maxillary second pre-molar (sPM), maxillary first molar (M1), maxillary second molar (M2) with the maxillary sinus floor using cone beam computed tomography (CBCT) in all three axial, sagittal and coronal sections from year 2016 to 2021. Three hundred and sixty teeth were examined through sixty full volumes CBCT scans of the patients in between year 2016-2021 in Indore, (MP, India). The Distances (D) between the examined roots and the sinus floor, were evaluated using CBCT in all three sections, and grouped in 7 classes. To simplify, Class 1 and 2 were grouped as Negative Configuration where apices are protruding into sinus floor, Class 3 as Zero and Class 4-7 as Positive configuration. The data were analyzed statistically using SPSS system. The prevalence of class 1 and 2 (negative configuration) was the highest for the Palatal of M1 (16.67%) followed by Distobuccal of M1 (13.34%). The prevalence of class 3 that is Zero configuration was the highest for the Mesiobuccal of M2 (63.33%). The results suggested all the three teeth roots showed closed proximity with sinus floor, closest relationship with the sinus floor was seen in palatal of M1 in this study.

Confronting implicit bias toward patients: a scoping review of post-graduate physician curricula.

BACKGROUND: Physicians' behavior may unknowingly be impacted by prejudice and thereby contribute to healthcare inequities. Despite increasingly robust data demonstrating physician implicit bias (The Office of Minority Health. Minority Population Profiles, 2021; COVID-19 Shines Light on Health Disparities, National Conference of State Legislatures 2021), the evidence behind how to change this with training programs remains unclear. This scoping review therefore reports on the implementation, outcomes, and characteristics of post-graduate physician implicit bias curricula. METHODS: The authors conducted a literature review using scoping review methodology. They searched 7 databases in February and November 2020 for English-language academic and gray literature on implicit bias curricula for physicians at all levels of post-graduate training. Ten reviewers screened studies for eligibility independently, then extracted data from these studies and compiled it into a chart and analytical summary. RESULTS: Of the 4,599 articles screened, this review identified 90 articles on implicit bias interventions for post-graduate physicians. Inductive data analysis revealed a spectrum of educational approaches, which were categorized int o 4 educational models called Competence, Skills-Based, Social Contact, and Critical Models. The most commonly reported strength was the interactive nature of the curricula (26%), and the most frequently identified challenges were related to time and resources available (53%). Half of the interventions discussed facilitator preparation, and the majority (62%) evaluated outcomes using pre and post self-assessments. CONCLUSIONS: This review provides a comprehensive synthesis of the literature on physician implicit bias curricula. It is our goal that this supports medical educators in applying and improving aspects of these interventions in their own programs.

Evidence of a Near-Threshold Resonance in

A narrow near-threshold proton-emitting resonance (E_{x}=11.4 MeV, J^{π}=1/2^{+}, and Γ_{p}=4.4 keV) was directly observed in ^{11}B via proton resonance scattering. This resonance was previously inferred in the ß-delayed proton emission of the neutron halo nucleus ^{11}Be. The good agreement between both experimental results serves as a ground to confirm the existence of such exotic decay and the particular behavior of weakly bound nuclei coupled to the continuum. R-matrix analysis shows a sizable partial decay width for both, proton and α (Γ_{α}=11 keV) emission channels.

Patients not taking a previously prescribed bone active medication now prescribed medication through Ontario FLS.

In an Ontario fracture liaison service (FLS), we compared medication prescription rates among patients not taking a previously prescribed bone active medication to those with no previous prescription. Prescription rates were similar between these two groups of patients. The FLS provided a secondary opportunity for patients to initiate bone active medication. PURPOSE: We compared bone active medication prescription rates among patients presenting to an Ontario fracture liaison service (FLS) who reported not taking a previously prescribed bone active medication to those with no history of prescription. METHODS: Eligible patients were those screened in 39 fracture clinics between July 1, 2017, and September 15, 2019, who were not taking bone active medication at the time of screening and classified as high risk for future fracture based on CAROC or FRAX. Sociodemographic and clinical risk factor variables were assessed at screening. Bone active medication prescription rate was assessed within 6 months of screening and defined as having received a prescription for the medication from either a specialist or primary care provider. In cases where a specialist report was not available, patient self-reported data were collected. The chi-square test of independence was used to assess differences in prescription rates. RESULTS: Of 17,575 patients screened, eligible patients were 350 with a previous prescription and 2644 without a previous prescription. Compared with patients who reported no previous prescription, those who had a previous prescription were older, more likely to be female and to report a previous fracture, and less likely to smoke. There was no statistically significant difference between the medication prescription rate of patients with a previous prescription (73.7%) compared to patients with no previous prescription (70.7%) (p = 0.157). CONCLUSION: A large jurisdiction-wide FLS approach provided a secondary opportunity to patients who were not taking a previously prescribed bone active medication to initiate that medication.

Identifying high risk patients post myocardial infarction with reduced left ventricular function using loop recorders INSPIRE-ELR clinical study.

AIMS: Sudden cardiac death (SCD) continues to be a devastating complication amongst survivors of myocardial infarction (MI). Mortality is high in the initial months after MI. The aims of the INSPIRE-ELR study were to assess the proportion of patients with significant arrhythmias early after MI and the association with mortality during 12 months of follow-up. METHODS: The study included 249 patients within 14 days after MI with left ventricular ejection fraction (LVEF) ≤35% at discharge in 11 hospitals in India. Patients received a wearable external loop recorder (ELR) 5 ± 3 days after MI to monitor arrhythmias for 7 days. RESULTS: Patients were predominantly male (86%) with a mean age of 56 ± 12 years. In 82%, reperfusion had been done and all received standard of care cardiovascular medications at discharge. LVEF was 32.2 ± 3.9%, measured 5.1 ± 3.0 days after MI. Of the 233 patients who completed monitoring (7.1 ± 1.5 days), 81 (35%) experienced significant arrhythmias, including Ventricular Tachycardia/Fibrillation (VT/VF): 10 (4.3%); frequent Premature Ventricular Contractions (PVCs): 65 (28%); Atrial Fibrillation (AF): 8 (3.4%); chronic atrial flutter: 4 (1.7%); 2nd or 3rd degree Atrioventricular (AV) block: 4 (1.7%); and symptomatic bradycardia: 8 (3.4%). In total, 26 patients died. Mortality was higher in patients with clinically significant arrhythmia (at 12 months: 23.6% vs 4.8% with 19 vs 7 deaths, hazard ratio (HR) = 5.5, 95% confidence interval (CI) 2.3 to 13.0, p < 0.0001). Excluding 7 deaths during ELR monitoring, HR = 4.5, p < 0.001. CONCLUSION: ELR applied in patients with acute MI and LV dysfunction at the time of discharge identifies patients with high mortality risk.

Fragility fracture patients with a history of prior fractures more likely to present with multiple risk factors: findings from a province-wide fracture liaison service.

We examined the demographic characteristics and risk factors of FLS fragility fracture patients who had sustained prior fragility fracture(s) and found that this is an important high-risk subgroup that warrants further attention within FLS priority pathways in order to disrupt their fragility fracture cycle. PURPOSE: Our primary objective was to examine whether fragility fracture patients presenting to a provincial fracture liaison service (FLS) having a history of prior fractures, versus those without, differ in demographic characteristics and risk factors for future fracture. A secondary objective was to understand if those who report two or more prior fractures differ from those reporting one prior fracture. METHODS: This cohort study included fragility fracture patients aged 50 + enrolled in the Ontario FLS between July 2017 and September 2019. Patients with versus those without prior fractures were compared on age, sex, index fracture site, biological parents' history of hip fracture, current fracture due to a fall, history of feeling unsteady when walking, history of falls in the past year, smoking, oral steroid use, and comorbid chronic conditions. Pearson's chi-square, Fischer's exact, and analysis of variance tests were used to assess differences. RESULTS: Among 14,454 patients, 16.8% (n = 2428) reported a history of one or more prior fractures after the age of 40. They were significantly more likely to be older, female, with a higher number of comorbidities, with greater incidence of falls, and feel unsteady when walking. Compared to those with one prior fracture, patients with greater than one prior fracture were more likely to report falls in the past year and feel unsteady when walking. CONCLUSION: Findings suggest that FLS fragility fracture patients who had sustained prior fragility fracture are an important high-risk subgroup that warrants further attention within FLS priority pathways in order to disrupt their fragility fracture cycle.

Safety assessment of Streptococcus salivarius M18 a probiotic for oral health.

The development of probiotics targeting non-intestinal body sites continues to generate interest amongst researchers, biotech companies and consumers alike. A key consideration for any bacterial strain to be developed into a probiotic is a robust assessment of its safety profile. Streptococcus salivarius strain M18 was originally isolated from a healthy adult and evaluated for its probiotic capabilities targeted to dental and oral health applications. This publication presents the safety characterisation of strain M18. Application of a diverse range of techniques showed that strain M18 can be specifically distinguished from other S. salivarius using a variety of molecular and phenotypic methodologies and that it lacks any relevant antibiotic resistance or virulence determinants. Direct comparison of the strain M18 safety profile with that of the prototype S. salivarius probiotic, S. salivarius strain K12, supports the proposition that strain M18 is indeed safe for probiotic application in humans.
