Iterative Design and Manufacturing of a 3D-Printed Pediatric Open and Laparoscopic Integrated Simulator for Hernia Repair (POLISHeR).

Background: Inguinal hernia is a common childhood pathology, making inguinal hernia repair (IHR) a key pediatric surgical procedure. Surgical success relies heavily on knowledge of groin anatomy, and both open and laparoscopic approaches require considerable repetition to master. As surgical simulators have been shown to improve performance for other surgical procedures, we developed a combined open and laparoscopic pediatric IHR simulator-named POLISHeR-to train residents, fellows, and practicing surgeons in both types of repair.

Sonic hedgehog medulloblastoma cells in co-culture with cerebellar organoids converge towards in vivo malignant cell states.

Background: In the malignant brain tumor sonic hedgehog medulloblastoma (SHH-MB) the properties of cancer cells are influenced by their microenvironment, but the nature of those effects and the phenotypic consequences for the tumor are poorly understood. The aim of this study was to identify the phenotypic properties of SHH-MB cells that were driven by the nonmalignant tumor microenvironment.

Methods: Human induced pluripotent cells (iPSC) were differentiated to cerebellar organoids to simulate the nonmaliganant tumor microenvironment.

Institutional Experience With Robotic Lobectomy After Neoadjuvant Immunotherapy and Chemotherapy.

Background: The real-world safety of robotic resections after neoadjuvant chemoimmunotherapy remains poorly defined in patients with non-small cell lung cancer. Due to reported increased operative challenges after neoadjuvant immunotherapy, we aim to describe our early institutional experience and outcomes after robotic resection in this clinical context.

Methods: We performed a retrospective chart review of patients with non-small cell lung cancer who underwent a robotic lobectomy, comparing patients from June 1, 2022, through October 31, 2023, who were treated with neoadjuvant chemoimmunotherapy consistent with the Checkmate-816 protocol and a control group with upfront resection.

Assessing Orofacial Esthetics in Prosthodontic Care: A Systematic Review and Meta-Analysis of Psychometric Properties.

Objective: To validate and ascertain the reliability of the Orofacial Esthetic Scale specifically within the context of prosthodontic patients, aiming to establish it as a credible and standardized tool for evaluating orofacial esthetics in this specialized cohort.

Methods: The systematic analysis adhered to the guidelines outlined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A systematic search using four databases PubMed /Medline, Web of Science, Scopus, Science Direct along with manual and grey literature (ProQuest and Google scholar) till 30 October 2023 was performed.

SARS-CoV-2 infections before, during, and after the Omicron wave: a 2-year Indian community cohort study.

Background: We measured the incidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and re-infections in an adult community-based cohort in southern India.

Methods: We conducted a 2-year follow-up on 1229 participants enrolled between May and October 2021. Participants provided vaccination histories, weekly saliva samples, and blood samples at 0, 6, 12, and 24 months.

Indonesian dentists' views on providing oral health care for older adults.

Background: With demographic changes in aging populations, dentists require special care protocols to treat older adults with diverse and complex oral health needs and problems. Knowledge, positive attitudes, and sufficient practice experience are essential components for promptly treating older adults. However, many dentists encounter multiple barriers influencing their willingness to provide care for older adults.

Biofilm Formation on Denture Base Material Reinforced With a Novel Organic Material.

Background: Microcrystalline cellulose (MCC) is a novel organic material developed by one of the authors in this study. When MCC was incorporated with conventionally available denture base resin, it demonstrated increased flexural strength and flexural modulus. However, it was speculated that because the material is organic, it can promote the growth of .

The respiratory route of transmission of virulent polioviruses.

Aims: The route of transmission of wild and circulating vaccine-derived polioviruses remains controversial, between respiratory and faecal-oral, and we aim to identify the most plausible one to settle the controversy.

Methods: We explored available epidemiological clues and evidence in support of either route in order to arrive at an evidence-based conclusion.

Results: Historically the original concept was respiratory transmission based on epidemiological features of age distribution, which was later revised to faecal-oral as the rationale for popularising the live attenuated oral polio vaccine in preference to the inactivated poliovirus vaccine.

Penicillin allergy de-labeling: Adaptation of risk stratification tool for patients and families.

Penicillin allergy is reported in 10% of the population; however, over 90% of patients are deemed non-allergic upon allergist assessment. The goal of this quality improvement project is to validate a patient-driven assessment tool to safely identify patients at low risk of penicillin allergy and de-label them. Pediatric patients and pregnant women referred to the institution's allergy clinics for penicillin allergy assessment were invited to use the patient tool to complete a self-assessment, resulting in the assignment of a risk category.

Human fascioliasis emergence in southern Asia: Complete nuclear rDNA spacer and mtDNA gene sequences prove Indian patient infection related to fluke hybridization in northeastern India and Bangladesh.

Fascioliasis is a snail-borne zoonotic disease with impact on the development of human subjects and communities. It is caused by two liver-infecting fasciolid trematode species, the globally-distributed and the Africa/Asia-restricted but more pathogenic, larger . is the cause of endemicity in livestock throughout the warm lowlands from Pakistan to southeastern Asia since old times.

Intestinal mucosal immunity is unimportant for polio eradication: the failure of oral polio vaccination.

Aims: To explore if intestinal immunity induced by infection with live viruses in the oral poliovirus vaccine (OPV) is essential, necessary or even helpful in interrupting transmission of wild poliovirus (WPV) for global polio eradication.

Methods: We reviewed the biology of virus-host interactions in WPV infection and its alterations by OPV-induced immunity for direct evidence of the usefulness of intestinal immunity. We also explored indirect evidence by way of the effect of the inactivated poliovirus vaccine (IPV) on the biology and on transmission dynamics of WPV.

Antipsychotics possess anti-glioblastoma activity by disrupting lysosomal function and inhibiting oncogenic signaling by stabilizing PTEN.

The repurposing of medications developed for central nervous system (CNS) disorders, possessing favorable safety profiles and blood-brain barrier permeability, represents a promising strategy for identifying new therapies to combat glioblastoma (GBM). In this study, we investigated the anti-GBM activity of specific antipsychotics and antidepressants in vitro and in vivo. Our results demonstrate that these compounds share a common mechanism of action in GBM, disrupting lysosomal function and subsequently inducing lysosomal membrane rupture and cell death.
