Purpose: Gender is a known social determinant of health which has been linked disparities in medical care. This study intends to assess the impact of gender on 90-day and long-term morbidity and mortality outcomes following supratentorial brain tumor resection in a coarsened-exact matched population.

Materials And Methods: A total of 1970 consecutive patients at a single, university-wide health system undergoing supratentorial brain tumor resection over a six-year period (09 June 2013 to 26 April 2019) were analyzed retrospectively.

Covid-19-associated neurological manifestations are being reported with increased frequency throughout the world. In a study from China, symptoms referable to peripheral nervous system (PNS) were described in approximately 9% of hospitalized Covid-19 patients. Common PNS symptoms reported in the study were loss of taste/smell and muscle pains.

Article Synopsis
  • Graphene (GR) and graphene oxide (GO) are potential materials for biomedical uses, but their safety and toxicity require careful evaluation.
  • Adult zebrafish were exposed to different concentrations of GR and GO for 14 days, and their behaviors were assessed through various tests.
  • The study found that exposure to GR and GO altered zebrafish behaviors and neurotransmitter levels, indicating potential toxicity and contributing to the understanding of these materials' biosafety.

Purpose: This study characterizes the association of risk factors including race, ethnicity, and insurance status with presenting visual acuity (VA) and diabetic retinopathy (DR) severity in patients initiating treatment with anti-vascular endothelial growth factor (VEGF) therapy for diabetic macular edema (DME).

Design: Retrospective, cross-sectional study.

Participants: The Academy Intelligent Research in Sight (IRIS) Registry database was queried for patients who initiated anti-VEGF injection treatment for DME between 2012 and 2020 (n = 203 707).

Background: Chordomas present challenges for en bloc surgical resection, which optimally reduces local recurrence and increases patient survival. Navigated ultrasonic osteotomy, also known as piezosurgery, provides a distinct advantage for achieving negative margins after en bloc resection.

Methods: Eight consecutive patients with chordomas (2 cervical, 3 lumbar, and 3 sacral) treated with navigated ultrasonic osteotomy to achieve en bloc resection were identified from our institutional spine tumor database (2016-2019) and retrospectively reviewed.

The COVID-19 pandemic has awakened the need for telemedicine and teleconsultation to continue medical care while maintaining social distancing for safety against infection. The concept of the electronic intensive care unit (e-ICU) is evolving rapidly in developed nations. e-ICU in developing countries like India not only has great potential but also has many roadblocks.

Objective: This study evaluated overlapping surgery on long-term outcomes following elective, single-level lumbar fusion on exact matched patients undergoing surgery with or without overlap.

Patients And Methods: 3799 consecutive adult patients undergoing single-level, posterior-only lumbar fusion over a six-year period at a multi-hospital university health system were retrospectively followed. Reported outcomes included reoperation, emergency department (ED) visit, readmission, overall morbidity and mortality in the 90 days following surgery.

Introduction: The LACE+ (Length of Stay, Acuity of Admission, Charlson Comorbidity Index (CCI) Score, Emergency Department (ED) visits within the previous 6 months) index has never been tested in a purely spine surgery population. This study assesses the ability of LACE + to predict adverse patient outcomes following discectomy for far lateral disc herniation (FLDH).

Patients And Methods: Data were obtained for patients (n = 144) who underwent far lateral lumbar discectomy at a single, multi-hospital academic medical center (2013-2020).

The relationship between social determinants of health (SDOH) and neurosurgical outcomes has become increasingly relevant. To date, results of prior work evaluating the impact of social determinants in neurosurgery have been mixed, and the need for robust data on this subject remains. The present review evaluates how gender, race, and socioeconomic status (SES) influence outcomes following various brain tumor resection procedures.

Objective: To assess the influence of race on short-term patient outcomes in a pituitary tumor surgery population.

Patients And Methods: Coarsened exact matching was used to retrospectively analyze consecutive patients (n = 567) undergoing pituitary tumor resection over a six-year period (June 07, 2013 to April 29, 2019) at a single, multi-hospital academic medical center. Black/African American and white patients were exact matched based on twenty-nine (29) patient, procedure, and hospital characteristics.

Aim: To compare the oocyte yield using three-dimensional (3D) automated and two-dimensional (2D) ultrasound-based follicle tracking in women undergoing fertilization-embryo transfer (IVF-ET).

Settings And Design: A randomized controlled trial was conducted in the Reproductive Medicine Unit of a teaching medical institute from January 2017 to December 2018.

Materials And Methods: A total of 130 patients undergoing IVF-ET were enrolled and randomized into two groups (65 patients in each group).

Background: Artificial intelligence (AI) has been described as the "fourth industrial revolution" with transformative and global implications, including in healthcare, public health, and global health. AI approaches hold promise for improving health systems worldwide, as well as individual and population health outcomes. While AI may have potential for advancing health equity within and between countries, we must consider the ethical implications of its deployment in order to mitigate its potential harms, particularly for the most vulnerable.

Background: Paraneoplastic Cerebellar degeneration (PCD) is one of the classical paraneoplastic syndromes (PNS) which is characterised by subacute onset, progressive cerebellar ataxia and is usually associated with small cell lung carcinoma, adeno carcinoma of breast and ovary followed by Hodgkin's lymphoma.

Objective: We herein report a case of subacute onset, progressive cerebellar ataxia in a 37-year-old female, who on evaluation was found to have non-Hodgkin's lymphoma and experienced good clinical response to treatment.

Discussion: As compared to solid tumours, chances of association of PNS with Lymphomas is quite low and there are only few case reports in the literature showing association of PCD with non-Hodgkin's lymphoma.

Importance: Police in Philadelphia, Pennsylvania, routinely transport patients with penetrating trauma to nearby trauma centers. During the past decade, this practice has gained increased acceptance, but outcomes resulting from police transport of these patients have not been recently evaluated.

Objective: To assess mortality among patients with penetrating trauma who are transported to trauma centers by police vs by emergency medical services (EMS).

The inhibition of Plasmodium cytosolic phenylalanine tRNA-synthetase (cFRS) by a novel series of bicyclic azetidines has shown the potential to prevent malaria transmission, provide prophylaxis, and offer single-dose cure in animal models of malaria. To date, however, the molecular basis of Plasmodium cFRS inhibition by bicyclic azetidines has remained unknown. Here, we present structural and biochemical evidence that bicyclic azetidines are competitive inhibitors of L-Phe, one of three substrates required for the cFRS-catalyzed aminoacylation reaction that underpins protein synthesis in the parasite.

Purpose: It is well documented that the interaction between many social factors can affect clinical outcomes. However, the independent effects of economics on outcomes following surgery are not well understood. The goal of this study is to investigate the role socioeconomic status has on postoperative outcomes in a cerebellopontine angle (CPA) tumor resection population.

Objective: Gender can contribute to adverse patient outcomes through social and biological factors. It is important to assess the effects of gender on long-term patient outcomes after care has already been accessed, in order to improve quality of care and mitigate healthcare disparities.

Patients And Methods: 277 consecutive patients undergoing cerebellopontine angle tumor resection over a six-year period (June 09, 2013 - April 29, 2019) at a university health system were retrospectively evaluated.
