Posterior Circulation Ischemic Stroke Is Associated with More Severe Forward Head Posture in Patients with Cervicalgia.

INTRODUCTION: Chronic risk factors of posterior circulation ischemic strokes remain unknown. There is, however, evidence that anatomical variations within the vertebrobasilar system could potentially lead to the development of posterior circulation strokes. We investigated the association of forward head posturing (FHP), a chronic anatomic change seen in patients with cervicalgia, with posterior circulation strokes. METHODS: In this case control study, we identified adult patients diagnosed with cervicalgia and ischemic posterior circulation infarcts from 2007 to 2023. Patients were paired to cervicalgia controls without posterior circulation stroke and matched for known risk factors. Patients' C0-C2 angle, C2-C7 angle, and sagittal vertical axis (SVA) shift were measured as metrics for FHP severity on lateral cervical spine x-rays. Paired T-tests were applied to compare patient stroke risk factors and FHP between groups. RESULTS: 206 patients (103 cases and 103 controls) were included with an average age of 64.4 years with 51.5% female. There were no statistically significant differences between the patients' risk factors for stroke, including hypertension, hyperlipidemia, diabetes, smoking, hypercoagulable state, and atrial fibrillation. There were statistically significant differences in C0-C2 angle (30.7 degrees vs 23.2 degrees, P-value=0.002) and SVA shift (35.4 mm vs 25.3 mm, P-value<0.001). CONCLUSIONS: This case control matched pair study found that within adults with cervicalgia, posterior circulation ischemic stroke was associated with more severe FHP as noted in C0-C2 angle and SVA shift measurements. This study further speculates that this association may be because of chronic changes in circulation flow dynamics within the vertebrobasilar system with the postural change.

Looking beyond duty hours: Offering a balanced quantitative-qualitative approach to resident burnout.

Burnout, stress and overwork are highly prevalent amongst junior training physicians worldwide, which explains the widespread phenomenon of physicians leaving the field and organised protests/strikes for better working conditions. Back in 2003, the mandatory duty hour restriction was a landmark intervention rolled out by the Accreditation Council for Graduate Medical Education that formally mandated limiting working hours of trainee residents to no more than 80 h per week, and not exceeding 24-h shifts with 6 added hours for education and handover. Nonetheless, 20 years later, this measure continues to be subject to multiple debates on its purported efficacy in achieving its intended objectives and fails to adequately prevent physician burnout and exodus. In our view, the current duty hour restriction model is, in and of itself, inadequate for combating burnout amongst medical residents for several reasons, including insignificant reduction in duty hours with suboptimal adherence/reporting, failure to account for off-site clinical and non-clinical duties, as well as nature of clinical work which typically involves high work intensity in less-than-optimal/unconducive work environments and significant psychoemotional stress. In this article, we offer our perspectives on pursuing a balanced approach towards both meaningful quantitative reduction in working hours as well as practical qualitative improvement in nature of clinical and non-clinical work that could collectively address resident burnout and improve work and training outcomes.

Clinical reasoning in real-world practice: a primer for medical trainees and practitioners.

Clinical reasoning is a crucial skill and defining characteristic of the medical profession, which relates to intricate cognitive and decision-making processes that are needed to solve real-world clinical problems. However, much of our current competency-based medical education systems have focused on imparting swathes of content knowledge and skills to our medical trainees, without an adequate emphasis on strengthening the cognitive schema and psychological processes that govern actual decision-making in clinical environments. Nonetheless, flawed clinical reasoning has serious repercussions on patient care, as it is associated with diagnostic errors, inappropriate investigations, and incongruent or suboptimal management plans that can result in significant morbidity and even mortality. In this article, we discuss the psychological constructs of clinical reasoning in the form of cognitive 'thought processing' models and real-world contextual or emotional influences on clinical decision-making. In addition, we propose practical strategies, including pedagogical development of a personal cognitive schema, mitigating strategies to combat cognitive bias and flawed reasoning, and emotional regulation and self-care techniques, which can be adopted in medical training to optimize physicians' clinical reasoning in real-world practice that effectively translates learnt knowledge and skill sets into good decisions and outcomes.

Evaluating the Impact of the COVID-19 Pandemic on Late-Canceled and No-Show Appointments at the Department of Neurological Surgery.

The coronavirus disease 2019 (COVID-19) pandemic resulted in unprecedented restrictions on the general public and disturbances to the routines of hospitals worldwide. These restrictions are now being relaxed as the number of vaccinated individuals increases and as the rates of incidence and prevalence decrease; however, they left a lasting impact on healthcare systems that is still being felt today. This retrospective study evaluated the total number of canceled or missed outpatient clinic appointments in a Neurological Surgery department before and after peak COVID-19 restrictions and attempted to assess the impact of these disruptions on neurosurgical clinical attendance. We also attempted to compare our data with the data from another surgical subspecialty department. We evaluated 32,558 scheduled appointments at the Loyola University Medical Center Department of Neurological Surgery, as well as 139,435 scheduled appointments with the Department of Otolaryngology. Appointments before April 2020 were defined as pre-COVID, while appointments during or after April 2020 were defined as post-COVID. Here, we compare no-show and non-attendance rates (no-shows plus late-canceled appointments) within the respective time range. Overall, we observed that before COVID-19 restrictions were put into place, there was an 8.9% no-show rate and a 17.4% non-attendance rate for the Department of Neurological Surgery. After COVID restrictions were implemented, these increased to 10.9% and 18.3%, respectively. Greater no-show and cancellation rates (9.8% in the post-COVID era vs 8.0% in the pre-COVID era) were associated with varying socioeconomic and racial demographics. African-American patients (2.56 times higher), new-visit patients (1.67 times higher), and those with Medicaid/Medicare insurance policies (1.48 times higher) were at the highest risk of no-show in the post-COVID era compared to the pre-COVID era.

The rise of medical influencers: The pros and the cons.

In the past few years, the online influencer industry has exponentially expanded, fuelled by the COVID pandemic lockdown, increased social media platforms and lifestyle appeal of influencership. This phenomenon has likewise infiltrated the medical field, where many healthcare practitioners have taken to social media platforms for content creation and influencer marketing. There are many reasons that underlie medical influencership - some may use it to improve public health literacy and correct medical misinformation, engage in medical advocacy or use the platform simply as a means of humanistic expression of the medical career, while others may seek to advertise private practice/medical products, boost personal reputation, and gain popularity and monetary benefits. Regardless of the underlying motivations of the medical influencers, some have fallen afoul of professionally accepted practices and ethical boundaries in their use of social media platforms, leading to serious consequences such as professional sanctioning or termination of employment. In this article, we hope to provide a comprehensive review of the 'good' (positive practices), the 'bad' (practices with possible unintended negative consequences) and the outright unprofessional or unethical behaviours aspects of social media use by medical influencers and offer practical strategies to ensure responsible and meaningful use of influencer platforms at both the physician and health systems level.

National Trends and Factors Associated with Voluntary Refusal of Glioblastoma Treatment: A Retrospective Review of the National Cancer Database.

OBJECTIVE: Adherence to combinatorial treatments are important predictors of improved long-term outcomes for patients with glioblastoma (GB); however, factors associated with refusal of surgery, chemotherapy, or radiotherapy (RT) by patients with GB have not been studied. METHODS: The National Cancer Database was queried from 2004 to 2018 to identify patients with a primary diagnosis of GB who underwent surgical resection alone or followed by either RT or chemotherapy. Adult patients who voluntarily rejected a physician's recommendations for 1 or more treatment were selected. Multivariable regression was used to identify factors associated with rejection of surgical resection, chemotherapy, and RT. Patients receiving treatment were 3:1 propensity score matched to those rejecting treatment and median overall survival (OS) was compared. RESULTS: 58,788 patients were included in the analysis. Factors associated with voluntary refusal of GB treatment included: old age, nonprivate insurance, female sex, Black race, comorbidities, treatment at a nonacademic facility, and living 55+ miles away from a treatment facility (P < 0.05). On propensity matched analysis, refusal of surgery conferred a 4 month decrease in OS (P < 0.001), RT an 8 month decrease in OS (P < 0.001), and chemotherapy a 7 month decrease in OS (P < 0.001). CONCLUSIONS: In patients with GB, age, sex, race, nonprivate insurance, medical comorbidities, distance from treatment facility, and geographic location were associated with refusal of surgery, postsurgical RT, and chemotherapy. In addition, treatment refusal had a significant impact on OS length.

Informed consent in clinical practice: Old problems, new challenges.

Informed consent is a fundamental tenet of patient-centred clinical practice as it upholds the ethical principle of patient autonomy and promotes shared decision-making. In the medicolegal realm, failure to meet the accepted standards of consent can be considered as medical negligence which has both legal and professional implications. In general, valid consent requires three core components: (1) the presence of mental capacity - characterised by the patient's ability to comprehend, retain information, weigh options and communicate the decision, (2) adequate information disclosure - based on the 'reasonable physician' or 'reasonable patient' standards and (3) voluntariness in decision-making. Nonetheless, in real-world clinical settings, informed consent is not always optimally achieved, due to various patient, contextual and systemic factors. In this article, I herein discuss three major challenges to informed consent in clinical practice: (1) patient literacy and sociocultural factors, (2) psychiatric illnesses and elderly patients with cognitive impairment and (3) artificial intelligence in clinical care, and sought to offer practical mitigating strategies to address these barriers.

When I say Socratic questioning.

In this article, Ng et al. define the core concepts of Socratic questioning and how it can be appropriately applied in clinical education.

Drug-induced chylothorax as a rare pleural complication in dasatinib therapy for chronic myeloid leukaemia.

Chylothorax is a lymphatic chylous pleural effusion typically associated with traumatic (iatrogenic, non-iatrogenic) and non-traumatic (infections, malignancy, lymphatic disorders) aetiologies. Drug-induced chylothorax is uncommon and mostly reported in association with BCR-ABL tyrosine kinase inhibitor therapy.
