Single organ metastatic sites in non-small cell lung cancer: Patient characteristics, treatment patterns and outcomes from a large retrospective Canadian cohort. Lung Cancer 2024; 192:107823. [PMID: 38763103 DOI: 10.1016/j.lungcan.2024.107823] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2024] [Revised: 04/17/2024] [Accepted: 05/12/2024] [Indexed: 05/21/2024]
Abstract
BACKGROUND There is a paucity of information about the characteristics, treatment patterns, and outcomes of non-small cell lung cancer (NSCLC) patients with single organ metastasis (SOM). METHODS This retrospective cohort study includes all patients with a diagnosis of stage IV NSCLC diagnosed from 2014 to 2016 and treated at Princess Margaret Cancer Centre. We compared baseline characteristics and patterns of metastatic sites between patients with SOM versus multiple (M)OM. Additionally, we identified treatment modalities and outcomes for patients with SOM. Cox multivariable models (MVA) were utilized to evaluate differences in overall survival (OS) between the SOM and MOM cohorts. RESULTS Of 893 pts analyzed, 457 (51 %) had SOM, while 436 (49 %) had MOM at initial diagnosis. Demographics were comparable between the two groups. Brain was the most common site of metastasis for SOM patients. When compared to the MOM group, the SOM group had lower percentages of liver and adrenal metastases. Amongst SOM patients, 54 % received single modality treatment, and 20 % did not receive any treatment for their SOM. In MVA, patients with liver (HR 2.4), bone (HR 1.8), and pleural (HR 1.7) metastasis as their SOM site had the worst outcomes, with median OS of 6.8 months, 12.1 months, and 13.0 months respectively. Patients with SOM had a significantly improved median OS compared to those with MOM (15.9 months vs. 10.6 months; HR 0.56, 95 % CI 0.47-0.66, p < 0.001). CONCLUSION In NSCLC patients who presented with SOM, survival correlated with the initial organ involved and was better overall compared to patients with MOM. SOM NSCLC may benefit from specific management strategies and SOM patients could be considered as a specific subgroup for survival analyses in observational and non-randomized interventional studies. In clinical trials, SOM can be considered as a stratification factor in the future.

Abstract
Background Prior research has demonstrated that platelet-rich plasma (PRP) has shown promising results in the treatment of knee osteoarthritis, lateral epicondylitis, and rotator cuff disease. However, there is a lack of standardization with PRP regarding its use for partial thickness rotator cuff tears (PTRCTs). The primary objective of this review is to assess the location of PRP injections in the shoulder, and how it corresponds to shoulder functional outcomes in PTRCTs. Methods Data sources included randomized controlled trials (RCTs) conducted between January 2010 and September 2021 with the terms PRP, partial thickness rotator cuff tears, intra-articular injections, subacromial injections, and intratendinous injections. Major inclusion criteria: partial thickness rotator cuff tears only, functional outcome scores pre-injection and post-injection, minimum 2-month follow-up time, and nonsurgical PRP injections only. Major exclusion criteria: PRP used as an adjunct therapy, full-thickness rotator cuff tears, and surgical intervention before treatment. Results A total of 8 RCTs were included which utilized PRP injected into the shoulder for PTRCTs. Studies were grouped by the location of the injection with the following breakdown: 1 glenohumeral joint, 4 subacromial bursa, and 3 intratendinous as the site of injection of PRP. Intra-articular PRP showed a 46.2% improvement (P < .05) in the Disabilities of the Arm, Shoulder, and Hand score at 12-month follow-up, however PRP compared to physical therapy had no statistical difference. For subacromial injections, one study showed no statistical difference between hyaluronic acid and PRP vs PRP, but both groups showed improvement compared to normal saline at 3, 6, and 12 months (P < .05). For intratendinous injections, PRP was found to be superior in the Shoulder Pain and Disability Index scores at 66.1% improvement (P < .05) at 3 months and 71.6% at 6 months (P < .05) after two PRP injections when compared to dry needling. Another study showed a statistically significant difference in ASES score when combining LP-PRP injection intratendinous and subacromial bursa when compared to corticosteroid at 3 months. Furthermore, at 6-month follow-up, the PRP group showed significant improvement in the Oxford Shoulder Score compared to a subacromial bursa corticosteroid group 53.8% vs 31.7% (P < .01). Conclusion Based on our review of current literature, there is inconclusive evidence of the ideal location to inject PRP when partial rotator cuff tear is present. Despite PRP showing improved functional outcomes in patients diagnosed with PTRCT regardless of the injection site, more research is needed to figure out the optimal concentration of PRP, frequency of injection, and who are ideal candidates when utilizing PRP for PTRCTs.

Abstract
Recent times have witnessed a growing demand for sustainable technology for food preservation that can retain its freshness, promises lower contents of additives and preservatives, safe consumption, eco-friendly milder processing technologies and eco-friendlier packaging solutions. Application of Biopolymers has served as the most sustainable and viable option to its synthetic counterparts. These biopolymers have been incorporated to develop biodegradable packaging like edible films and coatings owing to their biological origin. Nanoemulsion technology offers a leap forward to upgrade the features of conventional biodegradable packaging items. The present review discusses various trends and perspectives of nanoemulsion technology in post-harvest preservation for enhancing the shelf life of fresh fruits and vegetables. It investigates the interconnectedness between food preservation techniques, biodegradable packaging materials made from biopolymers, and nanoemulsions. It further addresses the preservation challenges post-harvest and underscores the limitations of conventional preservation methods, advocating for eco-friendly alternatives with a specific focus on the potential of nanoemulsions in enhancing food safety and quality. This review elaborates on the composition, formulation techniques, nanoemulsion products and role of nanoemulsions in the management of foodborne pathogens. Furthermore, it examines the potential health hazards linked to the use of nanoemulsions and stresses the significance of a regulatory framework for food safety. In conclusion, this review offers insights into the promising prospects of using nanoemulsions in food preservation.

Osteoma of the stylohyoid chain: A rare presentation in a CBCT study. Imaging Sci Dent 2024; 54:109-113. [PMID: 38571770 PMCID: PMC10985526 DOI: 10.5624/isd.20230222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 12/07/2023] [Accepted: 12/20/2023] [Indexed: 04/05/2024] Open
Abstract
A 54-year-old male patient presented for a periodic check-up at the dental clinic. A panoramic radiograph showed bilateral ossification of the stylohyoid ligament with an oval radiopacity on the right side. Cone-beam computed tomography revealed a well-defined, homogenous hyperdense entity from the lower third of the ossified stylohyoid ligament on the right side. The differential diagnosis of osteoma on the stylohyoid chain includes Eagle syndrome and benign tumors of the stylohyoid chain and adjacent structures. Osteoma rarely manifests in the neck. Even more infrequent are tumors originating from the stylohyoid chain, with only a single documented case of osteoma reported in the literature in 1993. Due to the asymptomatic status, no surgical intervention was advised, and the case would be monitored periodically. This case report describes the details of an osteoma that emerged from the stylohyoid chain, marking it as the second recorded occurrence of this highly rare condition.

A volumetric asymmetry study of gray matter in individuals with and without dyslexia. J Neurosci Res 2024; 102:e25305.

Abstract
Brain imaging work aimed at increased classification of dyslexia has underscored an important relationship between anterior (i.e., the inferior frontal gyrus; IFG) and posterior (i.e., superior temporal gyrus and supramarginal gyrus) brain regions. The extent to which the three components of the inferior frontal gyrus, namely the pars orbitalis, triangularis, and opercularis, are differentially related to the posterior regions, namely the superior temporal gyrus and supramarginal gyrus, needs further elucidation. Information about the nature of the anterior-posterior connections would facilitate our understanding of the neural underpinnings associated with dyslexia. Adult participants (N = 38; 16 with dyslexia) took part in an MRI study, whereby high-resolution structural scans were obtained. Volumetric asymmetry of the three regions of the IFG, the superior temporal gyrus, and the supramarginal gyrus was extracted. Significant differences were found for each of the three IFG regions, such that skilled readers had a greater leftward asymmetry of the orbitalis and triangularis, and greater rightward asymmetry of the opercularis, when compared to individuals with dyslexia. Furthermore, the pars triangularis was significantly associated with leftward asymmetry of the superior temporal gyrus for skilled but not dyslexic participants. For individuals with dyslexia, the cortical asymmetry of the IFG, and the corresponding connections with other reading-related brain regions, is inherently different from skilled readers. We discuss our findings in the context of the print-to-speech framework to further our understanding of the neural underpinnings associated with dyslexia.

The Role of Palliative Care Consultation in Withdrawal of Life-Sustaining Treatment among ICU Patients Receiving Veno-Venous Extracorporeal Membrane Oxygenation (VV-ECMO): A Retrospective Case-Control Study. Am J Hosp Palliat Care 2024; 41:150-157. [PMID: 37117039 PMCID: PMC10751975 DOI: 10.1177/10499091231173092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 04/30/2023] Open
Abstract
Background: Extracorporeal membrane oxygenation (ECMO) has extended the survivability of critically ill patients beyond their unsupported prognosis and has widened the timeframe for making an informed decision about the goal of care. However, an extended time window for survival does not necessarily translate into a better outcome and the sustaining treatment is ultimately withdrawn in many patients. Emerging evidence has implicated the determining role of palliative care consult (PCC) in direction of the care that critically ill patients receive. Objective: To evaluate the impact of PCC in withdrawal of life-sustaining treatment (WOLST) among critically ill patients, who were placed on venovenous ECMO (VV-ECMO) at the intensive care unit (ICU) of a tertiary care hospital. Methods: In a retrospective observational study, electronic medical records of 750 patients admitted to the ICU of our hospital between January 1, 2015, and October 31, 2021, were reviewed. Data was collected for patients on VV-ECMO, for whom WOLST was withdrawn during the ICU stay. Clinical characteristics and the underlying reasons for WOLST were compared between those who received PCC (PCC group) and those who did not (non-PCC group). Results: A total of 95 patients were included in our analysis, 63 in the PCC group and 32 in the non-PCC group. The average age of the study population was 48.8 ± 12.6 years, and 64.2% were male. There was no statistically significant difference between the two groups in terms of demographics or clinical characteristics at the time of ICU admission. The average duration of ICU stay and VV-ECMO were 14.1 ± 19.9 days and 9.4 ± 16.6 days, respectively. The number of PCC visits was correlated with the length of ICU stay. The average duration of ICU stay (40.3 ± 33.2 days vs 27.8 ± 19.3 days, P = .05) and ECMO treatment (31.9 ± 27 days vs 18.6 ± 16.1 days, P = .01) were significantly longer in patients receiving PCC than those not receiving PCC. However, the frequency of life sustaining measures or the underlying reasons for WOLST did not significantly differ between the two groups (P > .05). Conclusion: Among ICU patients requiring ECMO support, longer duration of ICU stay and treatment with a higher number of life-sustaining measures seemed to be correlated with the number of PCC visits. The underlying reasons for WOLST seem not to be affected by PCC.

Abstract
INTRODUCTION The United States Food and Drug Administration Manufacturer and User Facility Device Experience (MAUDE) dataset represents a unique source for post-market surveillance data on adverse events (AE). An analysis of AE with percutaneous mechanical circulatory support (pMCS) devices has previously been reported specifically for microaxial flow pumps. The characteristic AE for the intra-aortic balloon pump (IABP) have not been similarly analyzed or reported. MATERIAL AND METHODS All events in the MAUDE dataset between January 1, 2016 and December 31, 2021 were reviewed involving the Linear, Mega and Sensation devices (Datascope/Getinge, Wayne New Jersey). Data was analyzed by two authors and categorized based on AE type, date, event type and device-related or patient-related AE. RESULTS A total of 2795 AE were reported over five years. Device malfunction (91.4 %) was the most frequent classification followed by death (5.6 %) and injury (3.0 %). Catheter deformation/fracture/leak accounted for 37.9 % of total AEs. The most common patient event categorization was asymptomatic (90.8 %). Vessel damage/hemorrhage occurred in 1.4 % of reports. Death occurred in 5.6 % of reports and was associated with cardiac arrest in 110 of 156 events. Thrombus formation was described in 1.1 % of AEs. Device optic AE were common and unique to Sensation catheters. Calibration errors were also more common with Sensation (4.6 % versus 1.3 %) compared to other models. CONCLUSIONS Publicly reported AE with IABPs are predominantly device malfunctions without clinical sequelae. Injury, vascular damage, bleeding and thrombosis AEs are not frequent amongst reported AEs. Emphasis should be placed on understanding mechanisms of device malfunction in order to improve both reliability and user experience.

Effects of Laser Bandwidth in Direct-Drive High-Performance DT-Layered Implosions on the OMEGA Laser. PHYSICAL REVIEW LETTERS 2023; 131:105101.

Abstract
In direct-drive inertial confinement fusion, the laser bandwidth reduces the laser imprinting seed of hydrodynamic instabilities. The impact of varying bandwidth on the performance of direct-drive DT-layered implosions was studied in targets with different hydrodynamic stability properties. The stability was controlled by changing the shell adiabat from (α_{F}≃5) (more stable) to (α_{F}≃3.5) (less stable). These experiments show that the performance of lower adiabat implosions improves considerably as the bandwidth is raised indicating that further bandwidth increases, beyond the current capabilities of OMEGA, would be greatly beneficial. These results suggest that the future generation of ultra-broadband lasers could enable achieving high convergence and possibly high gains in direct drive ICF.

The intracortical excitability changes underlying the enhancing effects of rewards and punishments on motor performance. Brain Stimul 2023; 16:1462-1475.

Abstract
Monetary rewards and punishments enhance motor performance and are associated with corticospinal excitability (CSE) increases within the motor cortex (M1) during movement preparation. However, such CSE changes have unclear origins. Based on converging evidence, one possibility is that they stem from increased glutamatergic (GLUTergic) facilitation and/or decreased type A gamma-aminobutyric acid (GABAA)-mediated inhibition within M1. To investigate this, paired-pulse transcranial magnetic stimulation was used over the left M1 to evaluate intracortical facilitation (ICF) and short intracortical inhibition (SICI), indirect assays of GLUTergic activity and GABAA-mediated inhibition, in an index finger muscle during the preparation of sequences initiated by either the right index or little finger. Behaviourally, rewards and punishments enhanced both reaction and movement time. During movement preparation, regardless of rewards or punishments, ICF increased when the index finger initiated sequences, whereas SICI decreased when both the index and little fingers initiated sequences. This finding suggests that GLUTergic activity increases in a finger-specific manner whilst GABAA-mediated inhibition decreases in a finger-unspecific manner during preparation. In parallel, both rewards and punishments non-specifically increased ICF, but only rewards non-specifically decreased SICI as compared to neutral. This suggests that to enhance performance rewards both increase GLUTergic activity and decrease GABAA-mediated inhibition, whereas punishments selectively increase GLUTergic activity. A control experiment revealed that such changes were not observed post-movement as participants processed reward and punishment feedback, indicating they were selective to movement preparation. Collectively, these results map the intracortical excitability changes in M1 by which incentives enhance motor performance.

Abstract
INTRODUCTION Studies finding perioperative hyperglycaemia is associated with adverse patient outcomes in surgical procedures spurred the development of blood glucose guidelines at many institutions. In this trial, we will assess the implementation of a clinical decision support tool that is integrated into the intraoperative portion of our electronic health record and provides real-time best practice recommendations for intraoperative insulin dosing in surgical patients at high risk for hyperglycaemia. METHODS AND DESIGN We will assess this intervention using a sequential and repeated cross-over design at the institutional level with periods of time for wash-out, control and study intervention. The unit of analysis will be the surgical case. The primary outcome will be the frequency of hyperglycaemia (>180 mg/dL (10 mmol/L)) at first postoperative anaesthesia care unit measurement. There are several prespecified secondary analyses focused on perioperative glycaemic control. DISCUSSION This protocol and statistical analysis plan describes the methodology, primary and secondary analyses. The PeRiOperative Glucose PRAgMatic (PROGRAM) trial was approved by the Vanderbilt University Institutional Review Board (IRB), Vanderbilt University Medical Center, Nashville, Tennessee, USA (IRB, 220991). The study results will be disseminated via publication in a peer-reviewed journal and presented at national scientific conferences. The results of PROGRAM trial will inform best practice for perioperative standardised insulin administration in surgical patients at high risk of hyperglycaemia.

Efficient and Secure Encapsulation of a Natural Phase Change Material in Nanofibers Using Coaxial Electrospinning for Sustainable Thermal Energy Storage. ACS SUSTAINABLE CHEMISTRY & ENGINEERING 2023; 11:11570-11579.

Abstract
In this study, we present an ecofriendly technique for encapsulating lauric acid (LA), a natural phase change material, within polystyrene (PS) nanofibers through coaxial electrospinning. The resulting LAPS core-sheath nanofibers exhibited a melting enthalpy of up to 136.6 J/g, representing 75.8% of the heat storage capacity of pristine LA (180.2 J/g), a value surpassing all previously reported core-sheath fibers. Scanning electron microscopy revealed uniform LAPS nanofibers free of surface LA until the core LA feed rate reached 1.3 mL/h. As the core LA feed rate increased, the fiber diameter shrank from 2.24 ± 0.31 to 0.58 ± 0.45 μm. Infrared spectra demonstrated a proportional increase in the LA content with rising core LA injection rates. Thermogravimetric analysis found the maximum core LA content in core-sheath nanofibers to be 75.0%. Differential scanning calorimetry thermograms displayed a trend line shift upon LA leakage for LA1.3PS nanofibers. LAPS fibers containing 75.0% LA effectively maintained consistent cycling stability and reusability across 100 heating-cooling cycles (20-60 °C) without heat storage deterioration. The core LA remained securely within the PS sheath after 100 cycles, and the LAPS nanofibers retained an excellent structural integrity without rupture. The energy-dense and form-stable LAPS core-sheath nanofibers have great potential for various thermal energy storage applications, such as building insulation, smart textiles, and electronic cooling systems, providing efficient temperature regulation and energy conservation.

Abstract
Polycystic ovarian syndrome (PCOS) is a widespread, complex, and multi-system hormonal disorder that occurs in women of reproductive age. The wide variation in practice in the treatment of PCOS is a direct consequence of the lack of sufficient evidence on alternative treatment strategies, as well as a poor understanding of the disorder itself. The aim of our systematic review was to assess the therapeutic advantages and adverse effects of metformin (MET), a standard treatment modality, with myoinositol (MI), a recent substitute that may be used alone or in combination with other remedies to treat PCOS. A literature search was done using PubMed Central, PubMed, Medline, Cochrane, Science Direct, and Google Scholar. Studies were limited to those published in English between 2012 and 2022 that focused on the management of PCOS with both MET and MI. The systematic review complied with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Using standard quality assessment tools, two reviewers independently assessed the content of the incorporated studies. Three meta-analyses, eight randomized controlled trials (RCTs), and one non-randomized non-controlled trial (NN-RCT) were deemed eligible. Following extensive analysis, we found that MET and MI are comparable in their effects on clinical, hormonal, and biochemical profiles. MI, however, had a better safety profile and tolerance due to minimal side effects compared to MET. These results demonstrate the potential role of MI as a novel asset in the armamentarium in the management of PCOS.

Abstract
This study aims to characterize and contrast the triennial rates at which doctors prescribe PT, determine patient, doctor, and practicing characteristics related to every therapy suggestion, and assess pain relievers, lifestyle counseling, and PT as effective treatments for knee osteoarthritis (OA). We analyzed the National Ambulatory Medical Care Survey. Nonsteroidal anti-inflammatory drugs (NSAID), narcotics prescriptions, physical therapy referrals, and primary care physician visits for knee OA have been determined and evaluated. The average yearly rate after three years of therapy was determined. Using multivariable logistic modeling with adjustments for complicated sample design, we analyzed the relationships among patient, physician, and practice characteristics and treatments. Over time the patients were prescribed physical therapy to improve their lifestyle whereas the percentage of patients who were prescribed NSAIDs or drugs. Physical therapy, lifestyle therapy, and drugs were prescribed at similar rates across time for basic care doctor visits. There was an association between nonclinical characteristics and treatment suggestions, such as provider type, practice setting, and geographic proximity. Physical therapy (PT) and lifestyle counseling (LC) seem underused in patients with knee OA, but prescriptions for pain medication rose over the studied period. The treatment decisions varied due to variables outside of medicine. Increased usage of physical therapy and lifestyle changes, as well as decreased treatment variance for knee OA, are important areas for further study.

Abstract
Regular exercise helps to enhance health outcomes and lower risk factors, making it a crucial element in the prevention of chronic diseases. By being physically active, people can improve their general health and delay the onset of a number of chronic illnesses. For understanding the relationship between increased physical activity or decreased physical inactivity and favorable health outcomes, observational studies are the main source of information. We will look for systematic analyses of randomized controlled trials with a main emphasis on outcomes linked to diseases in the Cochrane Database of systematic studies. Evaluation will be limited to those in a few key chronic conditions. Preventing chronic illness and achieving better results in the management or treatment of chronic illness are the main outcomes of interest. For each chronic condition (such as the control of glucose in diabetes or any change in hypertension blood pressure), these results will be summarized and displayed. The design and implementation of chronic conditions, physical exercise illness conditions, and adverse physical activity-related events are of secondary interest. Our findings should help decision-makers, guideline organizations, and academics identify the most effective physical activity programs for major chronic disease management and prevention. Exercise and physical activity (PA) offers a non-invasive approach to the management of chronic disorders. More physiological, biochemical, and molecular data on the positive effects of PA and exercise on health should constitute a primary focus of future studies.

Abstract
BACKGROUND Diplomatic personnel frequently relocate as part of their roles, requiring them to adapt to various cultural and political conditions; many are also at risk of experiencing trauma from being deployed to high-threat postings. With diplomatic personnel having to balance the usual pressures of their work with the uncertainties of COVID-19 in recent years, it is particularly important now to understand how to protect their mental health. AIMS To synthesize existing literature on the well-being of diplomatic personnel to improve understanding of how to protect their mental health. METHODS A scoping review was carried out to explore what is already known about the well-being of staff working in diplomatic roles. Four databases were searched and reference lists, as well as one key journal, were hand-searched. RESULTS Fifteen relevant publications were included. There was little consensus as to how the psychological well-being of diplomatic personnel compares to other populations or which factors predict well-being. Diplomats' psychological responses to traumatic experiences appeared similar to those of other trauma-exposed occupational groups. CONCLUSIONS Further research is needed to better understand the well-being of diplomatic personnel, particularly those not deployed to high-threat posts.

Prevalence and Patterns of Nodal Metastasis Among Oral Cavity Cancer Patients: A Prospective Observational Study. J Maxillofac Oral Surg 2023; 22:245-251. [PMID: 36703656 PMCID: PMC9871083 DOI: 10.1007/s12663-022-01739-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Accepted: 05/24/2022] [Indexed: 01/29/2023] Open
Abstract
Introduction Lip and oral cavity cancer remains the most common cancer among Indian males and third most common cause of cancer-related deaths in India. Cervical lymph node metastasis is one of the most important prognostic factors in oral cavity cancer. The aim of present study was to estimate the prevalence of nodal involvement and analyse patterns of nodal metastasis in oral cavity cancer patients. Methods This prospective observational study was conducted between January 2019 and June 2020. Patients of oral cavity squamous cell carcinoma undergoing surgery with simultaneous neck dissection were included. Data pertaining to the clinical profile, treatment and histology details were collected and analysed. Results A total of 63 patients were included in present study. Out of 63 patients, unilateral neck dissection was performed in 47 (75%), while 16 (25%) underwent bilateral neck dissection. Overall clinical and pathological nodal positivity rates were 75% and 52%, respectively. Level I (48%) followed by IIa (20%) were most commonly involved stations. Combined involvement of level IV and V was seen in only 5%, and no skip metastasis was reported in level IV and V. Conclusion Level I and II are the most commonly involved stations in oral cavity squamous cell carcinoma (SCC). Oral SCC has a predictable nodal spread pattern with no skip metastasis to level IV/V noted in present study. There is a need for good quality randomised control trials to optimise the treatment protocols in clinically node-positive patients with respect to level IIB and V dissection.

Surgical outcomes of T4b oral cancers: assessment of prognostic factors and a need to re-evaluate the current staging system. Int J Oral Maxillofac Surg 2023; 52:143-151.

Abstract
T4b oral cancer is a broad umbrella term for all advanced oral cancers, the prognosis of which varies drastically for disease of the same stage, according to the extent of the masticator space involvement. This was a retrospective observational study including all consecutive T4b oral squamous cell carcinoma patients treated surgically between January 2015 and January 2016 and followed up until January 2020. The disease was classified as upper disease or lower disease based on the anatomical location in relation to an imaginary plane passing through the base of the retromolar trigone. The prime objective was to evaluate overall survival and prognostic factors affecting overall survival. The projected 5-year overall and disease-free survival rates were 40.7% and 35.6%, respectively. The assessment of prognostic factors revealed that lower disease (lower anatomical subsites), bone invasion, and lymph nodal spread significantly affected survival. Patients with disease in an upper anatomical location without bone and nodal involvement can achieve fairly good survival (projected 5-year overall survival of 64.2%) when compared to the other subsets of patients. We propose a re-evaluation of the current staging system based on the prognostic features, so that all patients are not considered under a single stage, since their survival differs significantly.

Abstract
OBJECTIVE Bariatric surgery is a successful treatment for sustainable weight loss and has been associated with improvement in cardiovascular function. Pregnancy after bariatric surgery is becoming increasingly common; however, little is known about the maternal cardiovascular system postsurgery. The aim of this study was to investigate maternal cardiovascular adaptation to pregnancy in women with previous bariatric surgery, compared with that in women with no history of weight-loss surgery and an early-pregnancy body mass index (BMI) similar to the presurgery BMI of the postbariatric women. METHODS This was a prospective, observational, longitudinal study conducted from April 2018 to June 2020 including 30 pregnant women who had undergone bariatric surgery and 30 who had not, matched for presurgery BMI. Participants were seen at three timepoints during pregnancy: 12-14, 20-24 and 30-32 weeks' gestation. At all visits, maternal blood pressure (BP) was measured and cardiac geometry and function were assessed using two-dimensional (2D) transthoracic echocardiography. On a subset of patients (15 in each group), 2D speckle tracking was performed to assess global longitudinal and circumferential strain. Offline analysis was performed, and multilevel linear mixed-effects models were used for all comparisons. RESULTS Compared with the no-surgery group, and across all trimesters, pregnant women with previous bariatric surgery had lower BP, heart rate and cardiac output and higher peripheral vascular resistance (P < 0.01 for all). Similarly, the postbariatric group demonstrated more favorable cardiac geometry and diastolic indices, including lower left ventricular mass, left atrial volume and relative wall thickness, together with higher E-wave/A-wave flow velocity across the mitral valve and higher mitral velocity (E') at the lateral and medial annulus on tissue Doppler imaging (P < 0.01 for all). There was no difference in ejection fraction, although global longitudinal strain was lower in postbariatric women (P < 0.01), indicating better systolic function. CONCLUSION Our findings indicate better maternal cardiovascular adaptation in women with previous bariatric surgery compared with presurgery BMI-matched pregnant women with no history of weight-loss surgery. © 2022 The Authors.

Observation of a Strongly Isospin-Mixed Doublet in ^{26}Si via β-Delayed Two-Proton Decay of ^{26}P. PHYSICAL REVIEW LETTERS 2022; 129:242502.

Abstract
β decay of proton-rich nuclei plays an important role in exploring isospin mixing. The β decay of ^{26}P at the proton drip line is studied using double-sided silicon strip detectors operating in conjunction with high-purity germanium detectors. The T=2 isobaric analog state (IAS) at 13 055 keV and two new high-lying states at 13 380 and 11 912 keV in ^{26}Si are unambiguously identified through β-delayed two-proton emission (β2p). Angular correlations of two protons emitted from ^{26}Si excited states populated by ^{26}P β decay are measured, which suggests that the two protons are emitted mainly sequentially. We report the first observation of a strongly isospin-mixed doublet that deexcites mainly via two-proton decay. The isospin mixing matrix element between the ^{26}Si IAS and the nearby 13 380-keV state is determined to be 130(21) keV, and this result represents the strongest mixing, highest excitation energy, and largest level spacing of a doublet ever observed in β-decay experiments.

Diagnosing low-mode (ℓ < 6) and mid-mode (6 ≤ ℓ ≤ 60) asymmetries in the post-stagnation phase of laser-direct-drive deuterium-tritium cryogenic implosions on OMEGA.

Abstract
Low- and mid-mode perturbations are possible candidates for performance limitations in cryogenic direct-drive implosions on the OMEGA laser at the Laboratory of Laser Energetics. Simulations with a 3D hydrocode demonstrated that hotspot imagers do not show evidence of the shell breakup in the dense fuel. However, these same simulations revealed that the low- and mid-mode perturbations in the dense fuel could be diagnosed more easily in the post-stagnation phase of the implosion by analyzing the peak in the x-ray emission limb at the coronal-fuel interface than before or at the stagnation phase. In experiments, the asymmetries are inferred from gated images of the x-ray emission of the implosion by using a 16-pinhole array imager filtered to record x-ray energies >800 eV and an x-ray framing camera with 40-ps time integration and 20-μm spatial resolution. A modal analysis is applied to the spatial distribution of the x-ray emission from deuterium and tritium cryogenic implosions on OMEGA recorded after the bang time to diagnose the low- and mid-mode asymmetries, and to study the effect that the beam-to-target ratio (Rb/Rt) has on the shell integrity.

Abstract
A series of two-dimensional particle-in-cell simulations with speckled laser drivers was carried out to study hot electron generation in direct-drive inertial confinement fusion on OMEGA. Scaling laws were obtained for hot electron fraction and temperature as functions of laser/plasma conditions in the quarter-critical region. Using these scalings and conditions from hydro simulations, the temporal history of hot electron generation can be predicted. The scalings can be further improved to predict hard x-rays for a collection of OMEGA warm target implosions within experimental error bars. These scalings can be readily implemented into inertial confinement fusion design codes.

Abstract
In laser-driven implosions for laboratory fusion, the comparison of hot-spot x-ray yield to neutron production can serve to infer hot-spot mix. For high-performance direct-drive implosions, this ratio depends sensitively on the degree of equilibration between the ion and electron fluids. A scaling for x-ray yield as a function of neutron yield and characteristic ion and electron hot-spot temperatures is developed on the basis of simulations with varying degrees of equilibration. We apply this model to hot-spot x-ray measurements of direct-drive cryogenic implosions typical of the direct-drive designs with best ignition metrics. The comparison of the measured x-ray and neutron yields indicates that hot-spot mix, if present, is below a sensitivity estimated as ∼2% by-atom mix of ablator plastic into the hot spot.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531.

Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
BackgroundAxial spondyloarthritis (axSpA) is characterised by inflammation of the sacroiliac joints and spine. Sleep disturbance, pain and fatigue are reported in the literature to be key symptoms and impacts of axSpA. Three customised Patient-Reported Outcomes Measurement Information System (PROMIS) Short Forms (Sleep Disturbance, Pain Interference and Fatigue), previously developed for use in rheumatoid arthritis, have been proposed for use in patients with axSpA to assess the key concepts.ObjectivesTo conduct in-depth qualitative interviews to further understand the patient experience of axSpA and evaluate the content validity of the three PROMIS Short Forms to support their use as endpoints in axSpA clinical trials.MethodsA non-interventional, cross-sectional qualitative (concept elicitation [CE] and cognitive debriefing [CD]) study was conducted in 28 adult patients with diagnosed axSpA, including radiographic axSpA (r-axSpA), also known as ankylosing spondylitis (AS, n=12), and non-radiographic axSpA (nr-axSpA, n=16). Patients took part in 90-minute telephone interviews. A semi-structured interview guide was used to assist discussions. The CE section used broad, open-ended questions to elicit information about symptoms and impact experienced by patients. The CD section involved a ‘think-aloud’ exercise in which patients read out each instruction, item and response option for the three PROMIS Short Forms and shared their feedback. Patients were also asked detailed questions about the relevance of the items, response options and recall period. Verbatim interview transcripts were subject to thematic and content analysis.ResultsPatients were from the United States (n=20) and Germany (n=8), mean age was 52.8 years, and 57% (n=16) were male; mean time since diagnosis of axSpA was 9.5 years (range 0.3–31.3 years). The CE section identified 12 distinct signs and symptoms that characterised patients’ experience of axSpA: pain, sleep problems, fatigue/tiredness, stiffness, swelling, vision/eye issues, restricted body movements, headache/migraine, spasms, change in posture/stature, balance/coordination problems and numbness. Pain, sleep problems and fatigue/tiredness were all reported to be experienced by ≥90% of patients, occurring simultaneously and exacerbating one another. 78% (n=21/27) of patients reported pain to be the most bothersome symptom, and 88% (n=23/26) described it as the symptom they would most like treatment to improve. Patients reported axSpA to impact their lives across six health-related quality of life (HRQoL) domains: physical functioning (100%), emotional wellbeing (89%), work/volunteering (79%), social functioning (75%), activities of daily living (61%) and cognitive functioning (54%). Impacts were most frequently described as being associated with pain, stiffness and fatigue. The experiences of symptoms and impacts were consistent between the AS and nr-axSpA patients. CD showed all three PROMIS instruments are conceptually comprehensive and well understood by patients with axSpA. No patients reported misunderstanding of instructions and/or items of the sleep disturbance instrument, and only one and four items had a small number of instances of misunderstanding for the fatigue and pain interference instruments, respectively. Across each instrument, all items were relevant to at least half of patients, and almost all patients reported the instruments to be appropriate for measuring their experience of sleep problems, pain and fatigue due to axSpA. Both AS and nr-axSpA patients confirmed the three PROMIS Short Forms to be relevant and appropriate for assessing their disease experience.ConclusionPain, sleep problems and fatigue are pivotal symptoms of axSpA and associated with HRQoL impacts. Interpretability and content validity of the PROMIS customised Short Forms have been confirmed, with each deemed to adequately assess key impacts associated with axSpA, making them suitable for use in clinical trials of patients with axSpA.Funding: GSK [209770]AcknowledgementsMedical writing support was provided by Tony Reardon, of of Aura, a division of Spirit Medical Communications Group Limited (Manchester, UK), and was funded by GlaxoSmithKline.Disclosure of InterestsAmy Findley Grant/research support from: employee of Adelphi Values, who received fees from GlaxoSmithKline for the conduct of this study, Jessica Middlehurst Grant/research support from: employee of Adelphi Values, who received fees from GlaxoSmithKline for the conduct of this study, Chloe Howse Grant/research support from: employee of Adelphi Values, who received fees from GlaxoSmithKline for the conduct of this study, Molly Clifford Grant/research support from: employee of Adelphi Values, who received fees from GlaxoSmithKline for the conduct of this study, William Neill Grant/research support from: employee of Adelphi Values, who received fees from GlaxoSmithKline for the conduct of this study, Sophi Tatlock Grant/research support from: employee of Adelphi Values, who received fees from GlaxoSmithKline for the conduct of this study, Wen-Hung Chen Shareholder of: GlaxoSmithKline, Employee of: GlaxoSmithKline, Marguerite Bracher Shareholder of: GlaxoSmithKline, Employee of: GlaxoSmithKline, Dharm Patel Shareholder of: GlaxoSmithKline, Employee of: GlaxoSmithKline

Abstract
Hypertension is highly prevalent in African American patients with a greater incidence of cardiovascular and renal complications of hypertension as compared to other ethnic groups. However, data is sparse on positive behavioral modifiers that can help lower hypertension.
Purpose:
To evaluate the effects of a hypertension survey on patients’ self-management and self-awareness.
Method:
In an urban outpatient clinic, a prospective randomized study was conducted in African American patients with controlled hypertension. Patients were randomly assigned to survey and control (no survey) groups and were followed up 3-6 months later. The survey included demographic information, weight, number of hypertension medications, self blood pressure (BP) monitoring, hypertension complication awareness, exercise frequency, and salt intake.
Results:
There were 117 respondents in the survey and control group. In the survey group, 54% (63 of 117) were males with an average age of 57 years. Average BP was 125/79 mm hg vs 127/80 mm hg post survey. On follow up average BMI decreased (35.1 vs 32.9, p = 0.038), self BP monitoring increased (25.6% vs 81.1% [30 vs 95 of 117, p < 0.005]), low salt diet intake increased (32% vs 60% [38 vs 71 of 117, p = 0.016]), exercise frequency 3-5 days/week increased (29% to 49% [34 vs 58 of 117, p = 0.028]), awareness of hypertensive complication improved (15% vs 74% [18 vs 87 of 117, p < 0.005]), and BP control without medication increased (4.3% vs 10.2% [5 vs 12 of 117, p = 0.046]). In the control group, 58% (67 of 117) were males with an average age of 56 years. Average BP was 126/80 vs 125/72 post survey. On follow up average BMI decreased (34.3 vs 33.8, p = 0.809), self BP monitoring increased from (28.2% vs 35% [33 vs 41of 117, p = 0.582]), Low salt diet intake increased (30% vs 36% [36 vs 43 of 117, p = 0.773 ]), exercise frequency 3-5 days/week decreased (31% to 24% [36 vs 29 of 117]), awareness of hypertensive complication improved (16% vs 23% [19 vs 28 of 11, p = 0.682]), and BP control without medication decreased (5.1% vs 1.7% [6 vs 2 of 117]).
Conclusion:
Our study suggests the action of completing a survey served as a positive behavioral and self-awareness modifier. The survey group showed a higher incidence of positive change compared to the control group.

Abstract
Enteric fever (EF) is an infection caused by the bacteria called Salmonella Typhi or Paratyphi. Infection is acquired through swallowing contaminated food or water. Most EF in England occurs in people returning from South Asia and other places where EF is common; catching EF in England is rare. The main symptom is fever, but stomach pain, diarrhoea, muscle aches, rash and other symptoms may occur. EF is diagnosed by culturing the bacteria from blood and/or stool in a microbiology laboratory. EF usually responds well to antibiotic treatment. Depending on how unwell the individual is, antibiotics may be administered by mouth or by injection. Over the past several years, there has been an overall increase in resistance to antibiotics used to treat enteric fever, in all endemic areas. Additionally, since 2016, there has been an ongoing outbreak of drug-resistant EF in Pakistan. This infection is called extensively drug-resistant, or XDR, EF and only responds to a limited number of antibiotics. Occasionally individuals develop complications of EF including confusion, bleeding, a hole in the gut or an infection of the bones or elsewhere. Some people may continue to carry the bacteria in their stool for a longtime following treatment for the initial illness. These people may need treatment with a longer course of antibiotics to eradicate infection. Travellers can reduce their risk of acquiring EF by following safe food and water practices and by receiving the vaccine at least a few weeks before travel. These guidelines aim to help doctors do the correct tests and treat patients for enteric fever in England but may also be useful to doctors and public health professionals in other similar countries.

A Behavioral Lifestyle Intervention to Improve Frailty in Overweight or Obese Older Adults with Type 2 Diabetes: A Feasibility Study. J Frailty Aging 2022; 11:74-82. [PMID: 35122094 PMCID: PMC8068458 DOI: 10.14283/jfa.2021.17] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Accepted: 03/26/2021] [Indexed: 12/14/2022]
Abstract
BACKGROUND Older adults with Type 2 diabetes (T2D) are more likely to be frail, which increases the risk for disability and mortality. OBJECTIVES To determine the feasibility of a behavioral lifestyle intervention, enhanced with mobile health technology for self-monitoring of diet and activity, to improve frailty in overweight/obese older adults (≥65 years) diagnosed with T2D. DESIGN, SETTING, AND PARTICIPANTS Single arm, 6-month study of a behavioral lifestyle intervention in 20 overweight/obese (BMI>25) older adults (≥ 65 years) with self-reported T2D diagnosis who owned a smartphone. A Fitbit tracker was provided to all participants for self-monitoring of diet and physical activity. Our primary outcome of feasibility was measured by session attendance, adherence to Fitbit usage to self-monitor diet and physical activity, and study retention. Secondary outcomes included the preliminary efficacy of the intervention on frailty, physical function, quality of life, and T2D-related outcomes. RESULTS Eighteen participants completed the study. The mean age was 71.5 (SD ± 5.3) years, 56% were female, and half were Hispanic. At baseline, 13 (72%) were pre-frail, 4 (22%) were frail, and 1 (6%) were non-frail. At follow-up, frailty scores improved significantly from 1.61 ± 1.15 to 0.94 ± 0.94 (p=0.01) and bodyweight improved from 205.66 ± 45.52 lbs. to 198.33 ± 43.6 lbs. (p=<0.001). CONCLUSION This study provides evidence for the feasibility of a behavioral lifestyle intervention in overweight/obese older adults with T2D and preliminary results support its potential efficacy in improving frailty score.

Effect of a very low negative dietary cation-anion difference (DCAD) diet on plasma and urine metabolomics of prepartum Holstein cows. JDS COMMUNICATIONS 2022; 3:59-65. [PMID: 36340673 PMCID: PMC9623625 DOI: 10.3168/jdsc.2021-0154] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Accepted: 09/09/2021] [Indexed: 06/16/2023]
Abstract
The objectives of this cross-sectional, nonintervention, observational study were to compare urine and blood parameters between cows consuming a positive dietary cation-anion difference (DCAD) diet [early dry cows, DCAD + 250 mEq/kg of dry matter (DM), n = 15] with the same cows consuming a negative DCAD diet (-220 mEq/kg of DM) 10 d after moving them from the early dry to the prepartum group. The most remarkable finding was that cows consuming the anionic diet had very low urine pH and very low base excess in blood, suggestive of uncompensated metabolic acidosis. Importantly, the metabolomics data revealed that only urine concentrations of essential and aromatic amino acids were decreased, and that concentrations of total nonessential amino acids and glucogenic amino acids were increased in plasma and reciprocally decreased in urine, suggesting that the cows fed anionic salts were attempting to meet a high glucose demand by mobilizing gluconeogenic amino acid reserves. Notably, the dietary anionic salts exerted marked effects on glycerophospholipids, with a reduction in most phosphatidylcholine containing diacyl (PC aa) and acyl-alkyl (PC ae) moieties in plasma and urine. Further characterization of these metabolomic profiles may lead to the development of novel biomarkers to identify cows susceptible to metabolic acidosis and other metabolic diseases.

Texts don't nudge: An adaptive trial to prevent the spread of COVID-19 in India. JOURNAL OF DEVELOPMENT ECONOMICS 2021; 153:102747. [PMID: 34602705 PMCID: PMC8464082 DOI: 10.1016/j.jdeveco.2021.102747] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Revised: 08/26/2021] [Accepted: 08/30/2021] [Indexed: 06/13/2023]
Abstract
We conduct an adaptive randomized controlled trial to evaluate the impact of a SMS-based information campaign on the adoption of social distancing and handwashing in rural Bihar, India, six months into the COVID-19 pandemic. We test 10 arms that vary in delivery timing and message framing, changing content to highlight gains or losses for either one's own family or community. We identify the optimal treatment separately for each targeted behavior by adaptively allocating shares across arms over 10 experimental rounds using exploration sampling. Based on phone surveys with nearly 4,000 households and using several elicitation methods, we do not find evidence of impact on knowledge or adoption of preventive health behavior, and our confidence intervals cannot rule out positive effects as large as 5.5 percentage points, or 16%. Our results suggest that SMS-based information campaigns may have limited efficacy after the initial phase of a pandemic.
