Abstract

Limited access to radiotherapy (RT) training in low- and middle-income countries (LMICs) hinders workforce growth and beneficial technology adoption. To this end, a virtual SBRT/SRS curriculum designed for RT professionals in Latin American LMICs was developed by a non-profit organization based in U.S. We report outcomes of large-scale, flexible participation. The program was announced through email and WhatsApp across Latin America, targeting centers with compatible technology to implement and master high-quality SBRT/SRS. Enrollment was free, open for 1 month, and allowed two types of participation: synchronous or asynchronous. Training was provided in Spanish with 15-weekly live, interactive video lectures for the participants in the synchronous cohort. Videos were recorded each week for the asynchronous cohort. The 4-month curriculum focused on simulation and registration of intracranial and extracranial sites, plan evaluation and optimization, site specific learning cases, quality assurance, and image-guided RT. Before the program and then again upon completion, synchronous participants self-evaluated confidence across 10 domains related to SBRT/SRS implementation and treatment on a 1-5 Likert scale and completed a knowledge-based 20-question multiple choice exam. Scores were analyzed using paired-t test. All participants were asked to describe their use of SBRT/SRS across brain, spine, prostate, lung, liver, and pancreas disease sites before vs. now within a 3-week window of the final training session. This cohort included 1,551 participants (1,128 synchronous; 418 asynchronous; 5 uncategorized) from 520 clinics in 24 countries. These comprised 678 (43.7%) radiation oncologists, 746 (48.1%) medical physicists, 92 (5.9%) radiation therapists, and 35 (2.3%) other professionals. Among synchronous participants, 799 (70.8%) provided paired responses after attending a mean 11.7 out of 15 sessions. Mean confidence across all SBRT/SRS domains increased from 2.95 to 3.61 (p < 0.01), and knowledge scores of SBRT/SRS increased from 45.1% to 52.7% (p < 0.01). From the beginning to the end of the course, the number of participants who said they were vs. are now not using, implementing, or already using SBRT/SRS changed significantly from 1884 to 993, 1132 to 1836, and 1667 to 1848, respectively. The shift to increased implementation and utilization held for both synchronous and asynchronous participants and was observed across all disease sites. This program, tailored to LMICs, saw substantial longitudinal participation and improved knowledge/implementation of SBRT/SRS. This is the first report of outcomes comparing virtual synchronous and asynchronous methods of participation. With participants selecting their preferred option, both methods appeared feasible and effective. Given the potential and position of e-learning, further research on e-learning outcomes for RT professionals in LMICs is warranted. [ABSTRACT FROM AUTHOR]

Abstract

Summary: The objective of this case–control study was to investigate the source of contamination and risk factors for colonisation and infection during an outbreak of extended-spectrum β-lactamase (ESBL)-producing Enterobacter cloacae in the University Medical Center Freiburg. A risk factor analysis was performed on 23 patients with ESBL-producing E. cloacae in the medical and surgical departments by comparing them with 46 non-colonised controls, who were matched for ward and length of hospital stay. For these, a risk factor analysis was conducted. Suspected sources for transmission of ESBL were examined and staff received training in infection control measures. The higher risk in colonised patients was attributed to dialysis with mobile units [odds ratio (OR): 4.00; 95% confidence interval (CI): 1.05–15.234; P =0.04]. Dialysis units were examined, but no contamination was found. Improvement in dialysis procedures, additional staff training and renewed training in standard precautions led to a substantial fall in case numbers. Risk factor analysis showed that colonised patients carried more invasive devices than controls (central venous catheter: OR: 2.50; 95% CI: 0.74–8.45; P =0.14; Foley catheter: 5.08; 0.61–42.23; P =0.13) and were given a greater number of different antibiotics (penicillins: 2.52; 0.71–8.89; P =0.15; fluoroquinolones: 2.37; 0.77–7.28; P =0.13). The differences in mobile dialysis frequency and antibiotic use between cases and controls were relevant, although the latter was not statistically significant. It was possible to contain the high frequency of ESBL colonisation or infection by reinforcing infection control measures and training the staff involved. [Copyright &y& Elsevier]

Abstract

Background: Despite a paucity of evidence-based guidelines, the use of PET/CT (positron emission tomography/computed tomography) in the management of cancer patients is increasing. As widespread clinical application increases, unexpected radiographic findings are occasionally identified. These incidental findings are often suspicious for a second primary malignancy. The purpose of this study was to determine the clinical impact of these incidental PET/CT findings. Methods: A query of our prospectively acquired Nuclear Medicine database was performed to identify patients with a known malignancy being staged or serially imaged with PET/CT. Patients with incidental findings suggestive of a second primary malignancy were selected. Statistical analysis was performed to determine the ability of PET/CT to identify a second primary malignancy. All PET/CT were interpreted by board certified nuclear radiologists. Results: Of 3,814 PET/CT scans performed on 2,219 cancer patients at our institution from January 1, 2005, to December 29, 2008, 272 patients (12% of all patients) had findings concerning for a second primary malignancy. An invasive work-up was performed on 49% (133/272) of these patients, while 15% (40/272) had no further evaluation due to an advanced primary malignancy. The remaining 36% (99/272) had no further evaluation secondary to a low clinical suspicion determined by the treating team, a clinical plan of observation, or patients lost to follow-up. Of the 133 patients evaluated further, clinicians identified a second primary malignancy in 41 patients (31%), benign disease in 62 patients (47%), and metastatic disease from their known malignancy in 30 patients (23%). The most common sites for a proven second primary malignancy were: lung (N = 10), breast (N = 7), and colon (N = 5). Investigation of these lesions was performed using several techniques, including 24 endoscopies (6 malignant). A surgical procedure was performed in 74 patients (29 malignant), and a percutaneous biopsy was performed on 34 patients (12 malignant). The overall positive predictive value for PET/CT to detect a second primary malignancy was 31% in this subgroup. At a median follow-up of 22 months, 9 of 41 patients with a second primary were dead of a malignancy, 20 were alive with disease, and 12 had no evidence of disease. Conclusion: Incidental PET/CT findings consistent with a second primary are occasionally encountered in cancer patients. In our data, approximately half of these findings were benign, a third were consistent with a second primary malignancy or a metastatic focus, and the remainder were never evaluated due to physician and patient decision. Advanced primary tumors are unlikely to be impacted by a second primary tumor suggesting that this subset of patients will not benefit from further investigation. Our data suggests that, despite the high rate of false positivity, incidental PET/CT findings should be investigated when the results will impact treatment algorithms. The timing and route of investigation should be dictated by clinical judgment and the status of the primary tumor. Further investigation will need to be performed to determine the long-term clinical impact of incidentally identified second primary malignancies. [Copyright &y& Elsevier]

Abstract

In patients implanted with durable left ventricular assist device (LVAD), the incidence of myocardial recovery leading to device explant or decommission is low, and reliable predictors of myocardial recovery remain lacking. Here, we investigate the potential of outflow cannula systolic slope as a non-invasive predictor of successful LVAD liberation amongst select cohort of patients with high recovery potential. We first identified a cohort of patients with high recovery likelihood by querying all LVAD patients at our institution who underwent reverse ramp test, a protocol developed to assess native myocardial contractility with sequential LVAD turn-down to minimal support. We then queried all echocardiographic studies of these patients within one year of the reverse ramp tests. In the subset of patients with adequate Doppler images of the outflow cannula, the systolic slope, a load-independent marker of contractility, was measured as previously described, and the clinical outcomes were correlated. Between September 1, 2015 and August 23, 2019, a total of 10 patients underwent reverse ramp test at our institution per published protocol. Of these, 4 patients had adequate echocardiographic window of the LVAD outflow cannula, and the systolic slope was calculated. 3 of the 4 patients had outflow cannula systolic slope of <1200 cm/s2 (813 ±148 cm/s2, range 651-1010 cm/s2; top figure), and none was able to achieve sustainable recovery (1 was bridged to transplant, 1 remains on LVAD support, and 1 was deceased). 1 out of the 4 patients had outflow cannula systolic slope >1200 cm/s2 (1788 cm/s2), and she underwent successful percutaneous decommission of her LVAD device (bottom figure). In a small case series of 4 patients from reverse ramp database with available echocardiographic images of the outflow cannula, high systolic slope value (>1200 cm/s2) identified the patient with clinical recovery leading to successful LVAD decommission.

Abstract

The hydrochemistry of minor elements and traces such as bromide, lithium, strontium, uranium and selenium, together with the chemical analysis of major ions, has been used in the study of salinization process. This process occurs in a semi-confined aquifer that corresponds to a Pliocene–Pleistocene fluvial environment. The semi-confined aquifer is located in the littoral of the cities of Ensenada and Berisso, in the region of the middle Río de la Plata estuary, Argentina. Groundwater salinization was detected in the semi-confined aquifer in the coastal plain area, with salt contents that increase from the loess plain towards the river. The content of major ions that predominate in sea water (Cl − , Na + and Mg 2 + ), as well as the Cl − /Br − and U vs. Cl − ratios, demonstrates that such salinization is related to sea water, which shows no correspondence with estuary water. In the salinized area, Li, Sr and Se enrichments occur, and are used as tracers of the average time that a substance remains in solution in sea water in the aquifer. The study of such minor ions together with the geological evolution of the area made it possible to recognize that the salt water in the semi-confined aquifer corresponds to a palaeo-intrusion of sea water associated with the Pleistocene–Holocene ingressions caused by the climate changes occurring during the Quaternary.

Abstract

Mar Chiquita is a coastal lagoon located in the Argentine Buenos Aires province in South America. The aim of this study is to estimate the annual contribution of inland waters to the carbon cycle in this lagoon's catchment by estimating the corresponding local carbon budget. Fifteen pairs of water samples were chosen to carry out hydrogeochemical modeling using PHREEQC software. Groundwater samples were considered as recharge water (initial solutions), while streamwater samples were taken as groundwater discharge (final solutions for inverse modeling/reference solutions for direct modeling). Fifteen direct models were performed, where each groundwater sample was constrained to calcite equilibrium under two different carbon dioxide partial pressure (PCO2) conditions: atmospheric conditions (log PCO2 (atm) = -3.5) and a PCO2 value of log PCO2 (atm) = -3. Groundwater samples are close to calcite equilibrium conditions. The calcite precipitation process is kinetically slower than gas diffusion, causing oversaturation of this reactant phase in streamwater samples. This was accompanied by a pH increase of approximately two units due to a PCO2 decrease. From the fifteen inverse models it was estimated that, of the total carbon that enters per year in the hydrological cycle of the study area, about 11.9% is delivered to the atmosphere as CO2 and around 6.7% is buried in sediments. This would indicate that 81.4% of the remaining carbon is retained in equilibrium within the system or discharged into the Mar Chiquita lagoon and/or directly to the ocean through regional flows.

Abstract

This is a single center prospective research study using an Apple iPhone 7 stock voice recorder application to assess the relationship between LVAD frequency and invasive hemodynamics. Patients were enrolled prior to their standard of care invasive speed adjustment/optimization study or routine RHC. A 35 second recorded auscultation using an iPhone 7 placed at the location of apex overlying the LVAD. Chest x-ray was utilized for estimation of ideal iPhone placement. Invasive hemodynamic data was recorded and baseline characteristics collected at time of acoustic acquisition. Acoustic data was analyzed post hoc using Audacity sound analysis software to produce frequency and decibel values for each audio file. Variation in frequency and decibels were observed between HVAD and HM3 despite differences in speed and rotational flow. 8 consecutive patients were studied, median age 59 years, male (63%) with 75% African American and 25% Caucasian. Mean height 173cm and weight 98kg. HVAD (3), Heartmate II (1) and Heartmate 3 (4) were included. Median CVP was 12mmHg, PCWP 17 mmHg, CO(F) 4.7, CI(F) 2.2, LVEDD 6.45cm and PASAT 62.9%. CVP was evaluated over a range of 7-15 mmHg and PCWP ranged from 10-23 mmHg. Mean frequency of HM3 was 53.5 Hz, HM2 68Hz and HVAD 49.7Hz. LVAD frequencies ranged from 48-63Hz in HM3, 68Hz HM2 and 47Hz-53Hz in HVAD. Pearson Correlation Coefficient R = -0.6616 (R² = 0.4377) for dB and PCWP (P=.07). This moderate negative correlation described a tendency for high dB variable scores to coincide with low PCWP scores. This interim analysis demonstrates a relationship between cardiac filling pressures and acoustics. Using a universal audio recording application may aid in the medical management of LVAD patients in the inpatient and outpatient setting. This cross platform technology should be further investigated as a potential diagnostic tool. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: Background: On occasion, patients followed with positron emission tomographic (PET)/computed tomographic (CT) imaging for nonbreast malignancies will have incidental breast findings concerning for second primary breast cancers. The aim of this study was to determine the predictive value of PET/CT imaging to identify breast cancers in these patients. Methods: Patients with primary nonbreast malignancies and findings concerning for second primary breast cancers were identified from a prospectively acquired nuclear medicine database from January 2005 to July 2008. Chart reviews were then performed. Results: Nine hundred two women underwent PET/CT imaging to evaluate nonbreast malignancies. Nine women (1%) had concerning breast findings, and 5 (56%) had subsequent breast cancer diagnoses. The positive predictive value of PET/CT imaging in these patients was 63%. Evidence of compliance with current screening guidelines was present in only 22% of these patients. Conclusions: The data suggest that findings concerning for an additional primary breast cancer should be evaluated and that age-appropriate screening tools should not be abandoned.

Abstract

Patients supported with left ventricular assist devices (LVADs) are burdened by frequent hemocompatibility-related adverse events related to patient-pump interactions. These predominantly vascular events include stroke, gastrointestinal bleeding, and pump thrombosis. Our center performs routine, invasive hemodynamic ramp speed titrations in LVAD patients to determine the optimal rotational speed after implantation. We sought to interrogate changes in vascular hemodynamics during an exercise ramp study to understand the influence of pump speed and exercise on outflow graft and cerebrovascular flow. A 71-year-old male patient supported by Heartware HVAD operating at a baseline speed of 2700 RPM presented for LVAD ramp and exercise study with vascular imaging. A right heart catheterization, echocardiography with Doppler imaging of the patient's LVAD outflow graft, and vascular Doppler of the left common carotid artery and middle cerebral artery were performed. The patient's LVAD operating speed was reduced to 2400 RPM and then increased stepwise to a maximum speed of 3000 RPM. At each increment of operating speed, Doppler imaging was attempted and right heart catheterization was repeated. After reviewing data from the ramp study, the patient's operating speed was set to 2900 RPM and then a staged exercise protocol with bicycle ergometer was performed. Pertinent findings of vascular imaging include a blunting of peak systolic to end-diastolic velocity ratio in vascular beds with incremental speed increase and partial recovery of pulsatility with exercise (Figure). This case demonstrates the influence LVAD speed adjustment and exercise have on carotid artery and outflow graft pulsatility. With exercise the outflow graft and carotid artery peak systolic and end-diastolic velocities were similar to those at the lowest LVAD pump speed, suggesting that intrinsic contractility and native LV unloading was restored with exercise despite a higher pump speed.

Abstract

Proton-proton collision data recorded in 2011 and 2012 by the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb(-1), are analysed to search for the charmless B-0 -> rho(0)rho(0) decay. More than 600 B-0 -> (pi(+)pi(-))(pi(+)pi(-)) signal decays are selected and used to perform an amplitude, analysis, under the assumption of no CP violation in the decay, from which the B-0 -> rho(0)rho(0) decay is observed for the first time with 7.1 standard deviations significance. The fraction of B-0 -> rho(0)rho(0) decays yielding a longitudinally polarised final state is measured to be f(L) = 0.745(-0.058)(+0.048)(stat) +/- 0.034(syst). The B-0 -> rho(0)rho(0) branching fraction, using the B-0 -> phi K*(892)(0) decay as reference, is also reported as B(B-0 -> rho(0)rho(0)) = (0.94 +/- 0.17(stat) +/- 0.09(syst) +/- 0.06(BF)) x 10(-6).
