Brainstem Hemorrhage Following Lumbar Drain for Post-traumatic Hydrocephalus.

Post-traumatic hydrocephalus is common after traumatic brain injury (TBI), particularly following decompressive craniectomy. Cerebrospinal fluid (CSF) removal by lumbar drain (LD) aids in the workup of post-traumatic hydrocephalus and serves as a bridge to definitive CSF diversion. Hemorrhagic complications following LD are rare but can include intracranial hemorrhage.

An Internally Validated Prognostic Risk-Score Model for Disease-Specific Survival in Clinical Stage I and II Merkel Cell Carcinoma.

Background: Merkel cell carcinoma (MCC) is a rare cutaneous malignancy for which factors predictive of disease-specific survival (DSS) are poorly defined.

Methods: Patients from six centers (2005-2020) with clinical stage I-II MCC who underwent sentinel lymph node (SLN) biopsy were included. Factors associated with DSS were identified using competing-risks regression analysis.

Background: Anxiety disorders are common in childhood and adolescence but evidence-based guidance on their management is limited in the UK. In the absence of guidelines, we examined what treatment young people with anxiety disorders receive in primary care in the year following diagnosis.

Method: We delineated a cohort of individuals diagnosed with anxiety disorders aged 10-18 using the Clinical Practice Research Datalink (CPRD).

The Impact of World Trade Center Related Medical Conditions on the Severity of COVID-19 Disease and Its Long-Term Sequelae.

The individuals who served our country in the aftermath of the attacks on the World Trade Center (WTC) following the attacks of 11 September 2001 have, since then, been diagnosed with a number of conditions as a result of their exposures. In the present study, we sought to determine whether these conditions were risk factors for increased COVID-19 disease severity within a cohort of N = 1280 WTC responders with complete information on health outcomes prior to and following COVID-19 infection. We collected data on responders diagnosed with COVID-19, or had evidence of receiving positive SARS-CoV-2 polymerase chain reaction or antigen testing, or were asymptomatic but had IgG positive antibody testing.

Clinical Considerations and Outcomes for Spine Surgery Patients with a History of Transplant: A Systematic Scoping Review Protocol.

Spine surgery patients with a history of organ transplantation are a complex population due to their unique anesthetic considerations, immunologic profiles, drug interactions, and potential organ dysfunction. It is common for these patients to develop neck/back pain and pathology that warrants surgical intervention. However, there is a relative dearth of literature examining their outcomes and clinical considerations.

The Macrotextured Implant Recall: Breast Implant-Associated-Anaplastic Large Cell Lymphoma Risk Aversion in Cosmetic and Reconstructive Plastic Surgery Practices.

Background: The recall of Allergan Biocell (Irvine, CA) devices due to the association between anaplastic large cell lymphoma (ALCL) and macrotextured breast implants means that plastic surgeons are faced with the challenge of caring for patients with these implants in situ. Cosmetic and reconstructive surgeons have been contacting affected patients to encourage them to follow up and discuss the most appropriate risk-reduction strategies.

Objectives: The aim of this study was to evaluate patient concerns about the risk of breast implant-associated ALCL (BIA-ALCL) and to compare management differences between cosmetic and reconstructive patients.

Correlation Between Intolerance of Uncertainty and Post-Operative Regret in Otolaryngology Patients.

Objective: To determine if intolerance of uncertainty, depression, anxiety, worry, or stress are related to post-op regret in otolaryngology patients.

Methods: Adult patients or parents giving consent for pediatric patients meeting criteria for otolaryngologic surgery were recruited and completed the Intolerance of Uncertainty Scale (IUS-12), Penn State Worry Questionnaire (PSWQ), and Depression, Anxiety and Stress Scale-21 (DASS-21) preop and the Decisional Regret (DR) scale 1-month post-op. Pearson correlations were calculated.

Sequence-specific H, C and N backbone NMR assignments for the N-terminal IgV-like domain (D1) and full extracellular region (D1D2) of PD-L1.

The co-inhibitory immune checkpoint interaction between programmed cell death-protein 1 (PD-1) and programmed cell death-ligand 1 (PD-L1) serves to regulate T-cell activation, promoting self-tolerance. Over-expression of PD-L1 is a mechanism through which tumour cells can evade detection by the immune system. Several therapeutic antibodies targeting PD-L1 or PD-1 have been approved for the treatment of a variety of cancers, however, the discovery and development of small-molecule inhibitors of PD-L1 remains a challenge.

Incidence of nonvalvular atrial fibrillation and oral anticoagulant prescribing in England, 2009 to 2019: A cohort study.

Background: Atrial fibrillation (AF) is an important risk factor for ischaemic stroke, and AF incidence is expected to increase. Guidelines recommend using oral anticoagulants (OACs) to prevent the development of stroke. However, studies have reported the frequent underuse of OACs in AF patients.

Cincinnati Prehospital Stroke Scale Implementation of an Urban County Severity-Based Stroke Triage Protocol: Impact and Outcomes on a Comprehensive Stroke Center.

Background And Purpose: Screening scales are recommended to assist field-based triage of acute stroke patients to designated stroke centers. Cincinnati prehospital stroke scale (CPSS) is a commonly used prehospital stroke screening tool and has been validated to identify large vessel occlusion (LVO). This study addresses the impact of county-based CPSS implementation to triage suspected LVO patients to a comprehensive stroke center (CSC).

The efficacy of immune checkpoint blockade for melanoma in-transit with or without nodal metastases - A multicenter cohort study.

Purpose: Guidelines addressing melanoma in-transit metastasis (ITM) recommend immune checkpoint inhibitors (ICI) as a first-line treatment option, despite the fact that there are no efficacy data available from prospective trials for exclusively ITM disease. The study aims to analyze the outcome of patients with ITM treated with ICI based on data from a large cohort of patients treated at international referral clinics.

Methods: A multicenter retrospective cohort study of patients treated between January 2015 and December 2020 from Australia, Europe, and the USA, evaluating treatment with ICI for ITM with or without nodal involvement (AJCC8 N1c, N2c, and N3c) and without distant disease (M0).

SARS-CoV-2 variant trends in Ireland: Wastewater-based epidemiology and clinical surveillance.

SARS-CoV-2 RNA quantification in wastewater is an important tool for monitoring the prevalence of COVID-19 disease on a community scale which complements case-based surveillance systems. As novel variants of concern (VOCs) emerge there is also a need to identify the primary circulating variants in a community, accomplished to date by sequencing clinical samples. Quantifying variants in wastewater offers a cost-effective means to augment these sequencing efforts.

Evaluation of the Indications for Sentinel Node Biopsy in Early-Stage Melanoma with the Advent of Adjuvant Systemic Therapy: An International, Multicenter Study.

Background: Patients presenting with early-stage melanoma (AJCC pT1b-pT2a) reportedly have a relatively low risk of a positive SNB (~5-10%). Those patients are usually found to have low-volume metastatic disease after SNB, typically reclassified to AJCC stage IIIA, with an excellent prognosis of ~90% 5-year survival. Currently, adjuvant systemic therapy is not routinely recommended for most patients with AJCC stage IIIA melanoma.
