Bridging the Knowledge Gap: A Toolkit on Reproductive Rights for Pediatric Surgeons in the Post-Dobbs Era.

BACKGROUND: The ripple effect of the Supreme Court ruling in Dobbs v. Jackson Women's Health Organization has impacted physicians and patients across numerous medical specialties. In pediatric surgery, the patient population ranges from fetus to the pregnant patient. There is a gap in the knowledge of pediatric surgeons regarding abortion laws and access. This project aims to bridge the gap by creating access to reliable resources which may be used to optimize patient care and support physicians. METHODS: We collaborated with the Reproductive Health Coalition, co-founded by the American Medical Women's Association and Doctors for America, to curate a list of resources beneficial to pediatric surgeons. RESULTS: We created a web-based toolkit with the purpose of providing easily accessible and reliable information on reproductive rights in the United States. We identified up-to-date resources on state-by-state abortion laws, legal resources, patient-centered information on obtaining abortion care, and resources for physicians interested in getting involved in advocacy. CONCLUSION: Pediatric surgery rests at a critical juncture with respect to reproductive rights in the United States. Our toolkit enables users to understand the current climate and identify next steps to advocate for patients and physicians amidst a formidable legal environment. LEVEL OF EVIDENCE: Level V.

Navigating the Impact of the Dobbs Decision: Perspectives from Pediatric Surgeons on Reproductive Health Care.

SUMMARY: Nationwide abortion restrictions resulting from the Dobbs v. Jackson Women's Health Organization (2022) decision have generated confusion and uncertainty among healthcare professionals, with concerns for liability impacting clinical decision-making and outcomes. The impact on pediatric surgery can be seen in prenatal counseling for fetal anomaly cases, counseling for fetal intervention, and recommendations for pregnant children and adolescents who seek termination. It is essential that all physicians and healthcare team members understand the legal implications on their clinical practices, engage with resources and organizations which can help navigate these circumstances, and consider advocating for patients and themselves. Pediatric surgeons must consider the impact of these changing laws on their ability to provide comprehensive and ethical care and counseling to all patients.

Extraction, characterization and biological activity of Galactomannan rich endosperm of Borassus flabellifer (Linn.) suitable for biofabrication of tissue scaffolds.

The study deals with the isolation, purification and characterization of galactomannan from the endosperm of Borassus labellifer (Linn.) to be used for biomaterial fabrication in tissue engineering (TE) applications. The isolated Borassus flabellifer (Linn.) galactomannan (BFG) through a sequential aqueous dissolution, centrifugation and ethanol precipitation presented a total yield of 19.77 ± 1.05 % (w/w) with advantageous compositional and functional properties. BFG was found to have mannose to galactose (M/G) ratio of 1.4:1. The molecular weight of BFG was found to be 4.9 × 105 g/mol and the molecular structure analysis by FTIR and NMR spectroscopy revealed the presence of α-linked, d-galactopyranose units and ß-linked, D-mannopyranose units. Further characterization by rheometer confirmed the non-Newtonian and pseudo-plastic behavior of different BFG concentrations and structural analysis by XRD and SEM confirmed the amorphous nature of BFG with the presence of pores and cervices on the rough surface. Finally, the favorable biological activity demonstrated in response to fibroblast cells against different BFG concentrations substantiates its relevance to be used in biofabrication of tissue scaffolds.

Diversity of electroencephalographic patterns during propofol-induced burst suppression.

Burst suppression is a brain state consisting of high-amplitude electrical activity alternating with periods of quieter suppression that can be brought about by disease or by certain anesthetics. Although burst suppression has been studied for decades, few studies have investigated the diverse manifestations of this state within and between human subjects. As part of a clinical trial examining the antidepressant effects of propofol, we gathered burst suppression electroencephalographic (EEG) data from 114 propofol infusions across 21 human subjects with treatment-resistant depression. This data was examined with the objective of describing and quantifying electrical signal diversity. We observed three types of EEG burst activity: canonical broadband bursts (as frequently described in the literature), spindles (narrow-band oscillations reminiscent of sleep spindles), and a new feature that we call low-frequency bursts (LFBs), which are brief deflections of mainly sub-3-Hz power. These three features were distinct in both the time and frequency domains and their occurrence differed significantly across subjects, with some subjects showing many LFBs or spindles and others showing very few. Spectral-power makeup of each feature was also significantly different across subjects. In a subset of nine participants with high-density EEG recordings, we noted that each feature had a unique spatial pattern of amplitude and polarity when measured across the scalp. Finally, we observed that the Bispectral Index Monitor, a commonly used clinical EEG monitor, does not account for the diversity of EEG features when processing the burst suppression state. Overall, this study describes and quantifies variation in the burst suppression EEG state across subjects and repeated infusions of propofol. These findings have implications for the understanding of brain activity under anesthesia and for individualized dosing of anesthetic drugs.

Screening and identification of potential inhibitor for visceral leishmaniasis (VL) through computational analysis.

AIM: The aim of this investigation is to detect potential inhibitor for visceral leishmaniasis through computational analysis. BACKGROUND: Leishmaniasis is categorized as a vector born pathogenic infection prevalent in tropical, subtropical, and in Mediterranean zones spread by intra-macrophage protozoa. The clinical syndrome of leishmaniasis is divided into the following type's namely cutaneous leishmaniasis, mucocutaneous leishmaniasis, visceral leishmaniasis, and dermal leishmaniasis. Trypanothione synthetase is a key enzyme involving in glutathione biosynthesis as well as hydrolysis. Trypanothione is one of the promising drug targets for parasites. Parasites are inimitable with concern to their dependence on trypanothione to regulate intracellular thiol-redox balance in fighting against oxidative stress and biochemical anxiety. However, trypanothione synthetase was presumed as the target therapeutic alternate in VL therapy. OBJECTIVE: The important objective of this current investigation is to identify or analyze the potential inhibitor for V. leishmaniasis through computational approaches which include virtual screening, molecular docking, ADME prediction, and molecular dynamic simulation. METHODS: An investigation was performed to develop a 3D protein structure, using computational screening among associated similar structured proteins from popular compound database banks such as Specs, Maybridge, and Enamine, to detect novel staging with a series of validation for emerging innovative drugs molecules. Modeled protein ligand complex was further analyzed to know the binding ability of the complex. Molecular dynamics were performed to ascertain its stability at 50 ns. RESULTS: Trypanothione synthetase overall ability in the outcome of series of analysis. Among three database compounds screened, the compound from the Specs database exhibited the better protein-ligand docking scores and fulfilled the drug-like properties through ADMET analysis, and the docked complexes had better stability throughout the simulation. Besides, the other two database leads fulfilled the pharmacological properties, and the complexes were stable in the simulation. CONCLUSION: By analyzing the various compounds from different databases, we concluded that the Specs database compound exhibits potential activity against the target protein and is considered a promising inhibitor for trypanothione synthetase.

Wearable Reduced-Channel EEG System for Remote Seizure Monitoring.

Epitel has developed Epilog, a miniature, wireless, wearable electroencephalography (EEG) sensor. Four Epilog sensors are combined as part of Epitel's Remote EEG Monitoring platform (REMI) to create 10 channels of EEG for remote patient monitoring. REMI is designed to provide comprehensive spatial EEG recordings that can be administered by non-specialized medical personnel in any medical center. The purpose of this study was to determine how accurate epileptologists are at remotely reviewing Epilog sensor EEG in the 10-channel "REMI montage," with and without seizure detection support software. Three board certified epileptologists reviewed the REMI montage from 20 subjects who wore four Epilog sensors for up to 5 days alongside traditional video-EEG in the EMU, 10 of whom experienced a total of 24 focal-onset electrographic seizures and 10 of whom experienced no seizures or epileptiform activity. Epileptologists randomly reviewed the same datasets with and without clinical decision support annotations from an automated seizure detection algorithm tuned to be highly sensitive. Blinded consensus review of unannotated Epilog EEG in the REMI montage detected people who were experiencing electrographic seizure activity with 90% sensitivity and 90% specificity. Consensus detection of individual focal onset seizures resulted in a mean sensitivity of 61%, precision of 80%, and false detection rate (FDR) of 0.002 false positives per hour (FP/h) of data. With algorithm seizure detection annotations, the consensus review mean sensitivity improved to 68% with a slight increase in FDR (0.005 FP/h). As seizure detection software, the automated algorithm detected people who were experiencing electrographic seizure activity with 100% sensitivity and 70% specificity, and detected individual focal onset seizures with a mean sensitivity of 90% and mean false alarm rate of 0.087 FP/h. This is the first study showing epileptologists' ability to blindly review EEG from four Epilog sensors in the REMI montage, and the results demonstrate the clinical potential to accurately identify patients experiencing electrographic seizures. Additionally, the automated algorithm shows promise as clinical decision support software to detect discrete electrographic seizures in individual records as accurately as FDA-cleared predicates.

Factors predicting outcome after salvage treatment for stage IV oral squamous cell carcinoma: Evidence of the potential importance of the cyclooxygenase-2-prostaglandin E2 pathway.

BACKGROUND: We determined the clinicopathological factors that predicted outcome after salvage treatment for stage IV oral squamous cell carcinoma (OSCC). Additionally, the prognostic significance of the cyclooxygenase-2 (COX-2)/microsomal prostaglandin-E synthase-1 (mPGES-1) pathway was evaluated. METHODS: Thirty-one patients who underwent salvage surgery were included. COX-2 and mPGES-1 levels were quantified by real time polymerase chain reaction (PCR). RESULTS: The 2-year disease-free and overall survival rates were 46% and 53%, respectively. Adequacy of initial treatment, tobacco smoking, and the presence of pathological risk factors were predictive of mortality. In patients who had not received chemotherapy before salvage surgery, high levels of intratumoral COX-2 and mPGES-1 were associated with poor prognosis. By contrast, high intratumoral COX-2 and mPGES-1 after chemotherapy were associated with improved outcomes. CONCLUSION: Clinicopathological factors may inform treatment decisions in patients with stage IV OSCC. Expression patterns of COX-2 and mPGES-1 correlated with outcome and warrant further investigation. © 2014 Wiley Periodicals, Inc. Head Neck 37: 1142-1149, 2015.

Tablet in the bronchus--an unusual cause for persistent cough in a 64 year old gentleman.

Foreign body aspiration in adults without any background risk factors is uncommon. We report a 64 year gentleman evaluated for persistent cough incidentally detected to have a foreign body (FB) in the left main bronchus (LMB), which after removal by rigid bronchoscopy turned out to be a tablet. This demonstrates the possible risk of silent aspiration of solid foreign bodies and in our case presenting as a persistent cough after months of aspiration. Bronchoscopic evaluation should be carried out in the differential diagnosis of persistent or recurrent pulmonary symptoms.

Cancers of upper gingivobuccal sulcus, hard palate and maxilla: A tertiary care centre study in North India.

INTRODUCTION: Oral cancer is the sixth most common malignancy in the world, and the third most common in southeast Asia. Cancers of the upper gingivo-buccal complex are uncommon and reported infrequently. In this article, we have assessed the clinicopathological features of such cancers and their optimal management. MATERIALS AND METHODS: We studied 64 patients with cancer of the upper gingivobuccal sulcus (GBS), hard palate, and maxilla seen between February 2009 and 2013 over a span of 4 years. RESULTS: Of the 64 patients studied, 45 were male. The mean age at presentation was 50.59 years (24-80 years). Of the 64, 48 patients (75%) had a history of substance abuse in the form of tobacco chewing, smoking or alcohol. On presentation, 48 of the 64 patients (75%) had T4 disease, eight had T3, six had T2 lesion, one had T1 lesion, and 1 patient had a neck recurrence with distant metastatic disease (Tx). Out of the 64 patients, 31 had clinically palpable neck disease and two patients had distant metastatic disease. Of the 64 patients, 58 had squamous cell carcinoma, two had adenoid cystic carcinoma of the hard palate and one patient each had melanoma, sarcoma, neuroendocrine tumor, and mucoepidermoid carcinoma. Following imaging, 18 patients (28.13%) underwent upfront surgery and six following neoadjuvant chemotherapy. 14 of the 24 patients operated had simultaneous neck dissection. 2 patients with distant metastasis and 1 with cavernous sinus thrombosis received palliative chemotherapy. Out of the 64 patients, the other 24 who were inoperable were referred to radiotherapy. CONCLUSION: Upper GBS, hard palate and maxilla cancers are uncommon and are diagnosed at an advanced stage due to delay in presentation and ignorance of our population. Surgery offers the best form of treatment. NACT may be tried to downstage the disease in selected patients with borderline operable disease. However, generous margins should be taken post chemotherapy with concomitant neck dissection. Adjuvant radiotherapy is recommended in selected patients after surgery.

Age related changes in postural stability.

Postural instability is a commonly encountered problem in elderly population. In a large number of persons this can be attributed to the physiological changes associated with aging. To investigate the changes in postural stability with aging this study was conducted in 64 healthy volunteers aged eight to seventy years using dynamic posturography. Three tests, namely sensory organization test, limits of stability and rhythmic weight shift which included a total of ten parameters were done. Of these, equilibrium score, strategy score, reaction time, movement velocity and on axis velocity showed statistically significant deterioration with progression of age. Disturbances in postural stability were detected from the fourth decade onwards in the population studied. This instability was not related to any disease process and possibly reflects the process of aging. Adequate precautionary measures should be taken by elderly persons to avoid the possible adverse consequences of postural instability.
