Cardiovascular disease is common in patients with prostate cancer and is a significant cause of death. Cardiovascular risk factors are frequent in this population and are often not addressed to thresholds recommended by cardiovascular practice guidelines. Androgen deprivation therapy reduces muscle strength and increases adiposity, increasing the risk for diabetes and hypertension, although its relationship with adverse cardiovascular events requires confirmation.

Optimal treatment strategies for metastatic hormone-sensitive prostate cancer (mHSPC) are evolving with novel multimodal approaches. For well-selected patients, early local radiotherapy can play a pivotal role in high-volume mHSPC. Radiotherapy controls local disease, reduces symptoms, and may potentially delay castration resistance, warranting its consideration alongside systemic therapies in high-volume mHSPC.

Background: The epidemiology of idiopathic pediatric epilepsy globally continues to be defined. To date there has been no evaluation of how national food availability may associate with the incidence and disability-adjusted life years (DALYs) lost from this condition. Correspondingly, the aim of this study was to define if such associations exist.

Background: There are limited data on the physical effects of androgen deprivation therapy (ADT) for prostate cancer (PC), and on the relationships of such measures of adiposity and strength to cardiovascular outcomes.

Objectives: The primary objective of this study was to evaluate the relationships of measures of adiposity and strength to cardiovascular outcomes (cardiovascular death, myocardial infarction, stroke, heart failure, arterial revascularization, peripheral arterial disease, and venous thromboembolism) in patients with PC. A secondary objective was to characterize the relationships between ADT use and 12-month changes in these physical measures.

Background: Prostate cancer (PCa) management commonly involves the utilization of prostate radiotherapy (PRT), pelvic nodal radiotherapy (PNRT), and androgen deprivation therapy (ADT). However, the potential association of these treatment modalities with bone marrow (BM) suppression remains inadequately reported in the existing literature. This study is designed to comprehensively evaluate the risk of myelosuppression associated with PRT, shedding light on an aspect that has been underrepresented in prior research.

Article Synopsis
  • The Prostate Cancer Study 5 (PCS5) aimed to compare the effectiveness and side effects of two types of radiotherapy: conventional fractionated radiotherapy (CFRT) and hypofractionated radiotherapy (HFRT) for high-risk prostate cancer patients.
  • The study included 329 patients who were randomly assigned to receive either CFRT or HFRT, with the primary focus on comparing toxicity and secondary outcomes like survival rates over a 5-year median follow-up.
  • Results showed no significant differences in overall survival or other survival metrics between the two treatments, suggesting that HFRT could be adopted as a new standard treatment option for high-risk patients.

Hydrocephalus is a neurosurgical condition that is highly prevalent in pediatric medicine. In the infant population, there is a distinct set of features that all primary pediatricians would benefit from understanding. Infant hydrocephalus can present prenatally on imaging and postnatally with symptomatic enlargement of the head and associated skull features and raised intracranial pressures.

Background: Surgical selective dorsal rhizotomy (SDR) in appropriate pediatric cerebral palsy patients is an effective treatment for spasticity. However, there remains heterogeneity reported in postoperative pain management with and without opioid medication in this delicate cohort. The objective of this study was to aggregate pertinent metadata by means of systematic review to summarize all relevant postoperative pain regimens in the literature.

Background: Shunt failure is an undesirable but common occurrence following neurosurgical shunting for pediatric hydrocephalus. Little is known about the occurrence of failure in lower-middle income country (LMIC) settings in South America. The objective of this study was to evaluate shunt failure in the sole publicly funded pediatric hospital in La Paz, Bolivia, with limited resources.

Objective: The current pediatric neurosurgery capacity in lower-middle-income countries (LMICs) in South America is poorly understood. Correspondingly, the authors sought to interrogate the neurosurgical inpatient experience of the sole publicly funded pediatric hospital in one of the largest regional departments of Bolivia to better understand this capacity.

Methods: A retrospective review of all neurosurgical procedures performed at the Children's Hospital of La Paz, Bolivia (Hospital del Niño "Dr.

Background: How pediatric medulloblastoma patients fare in Lower Middle-Income Country (LMICs) in South America is not well understood. Correspondingly, the aim of this study was to summarize the pediatric neurosurgical experience of an institution in La Paz, and compare outcomes to that of a generalized High Income Country (HIC) United States (US) experience.

Prostate-specific membrane antigen (PSMA) is highly expressed in prostate cancer and a therapeutic target. Lutetium-177 (Lu)-PSMA-617 is the first radioligand therapy to be approved in Canada for use in patients with metastatic castration-resistant prostate cancer (mCRPC). As this treatment represents a new therapeutic class, guidance regarding how to integrate it into clinical practice is needed.

Article Synopsis
  • There's a meeting called the Canadian Consensus Forum (CCF3) where doctors talked about how to manage prostate cancer (PCa) better.
  • They discussed important topics like treatment options and how to test for the disease using new technology.
  • The doctors agreed on more than half of the questions discussed, helping to guide future treatment and research to improve care for patients with prostate cancer.

Background: Cellular senescence can have positive and negative effects on the body, including aiding in damage repair and facilitating tumor growth. Adamantinomatous craniopharyngioma (ACP), the most common pediatric sellar/suprasellar brain tumor, poses significant treatment challenges. Recent studies suggest that senescent cells in ACP tumors may contribute to tumor growth and invasion by releasing a senesecence-associated secretory phenotype.

Background: There continues to be clinical significance of pediatric sports-related concussion (pSRC) for pediatric specialists. The overall trends of pSRC are not well understood. The aim of this study was to summarize the epidemiology of pSRC presenting to the emergency room (ER) in the United States (US) over the last decade.

Background: Awake craniotomy allows neurosurgeons to make critical decisions when operating in eloquent regions of the brain. The phenomenon of "waking up" during surgery is underexplored in pediatric patients, and the operative outcomes following awake craniotomy are not well understood. Correspondingly, the aim of this study was to quantitatively aggregate the contemporary metadata regarding the operative outcomes of awake craniotomy when used in the pediatric setting.

Purpose: Around 40% of men with intermediate-risk or high-risk prostate cancer will experience a biochemical recurrence after radical prostatectomy (RP). The aim of this review is to describe both toxicity and oncological outcomes following stereotactic body radiation therapy (SBRT) delivered to the prostate bed (PB).

Method: In april 2023, we performed a systematic review of studies published in MEDLINE or ClinicalTrials.

Background: Pediatric tumors of the brain and central nervous system (CNS) are a worldwide issue with variances in epidemiology. How exactly incidence and mortality rates have changed over time has not been summarized. Correspondingly, the aim of this study was to quantitively define the global, regional, and national epidemiological trends of these tumors.

Background: Chiari malformation type I (CIM) diagnoses have increased in recent years. Controversy regarding the best operative management prompted a review of the literature to offer guidance on surgical interventions.

Objective: To assess the literature to determine (1) whether posterior fossa decompression or posterior fossa decompression with duraplasty is more effective in preoperative symptom resolution; (2) whether there is benefit from cerebellar tonsillar resection/reduction; (3) the role of intraoperative neuromonitoring; (4) in patients with a syrinx, how long should a syrinx be observed for improvement before additional surgery is performed; and 5) what is the optimal duration of follow-up care after preoperative symptom resolution.
