A rare case of syphilitic Charcot joint involving left elbow.

Charcot arthropathy is characterized by joint dislocations, pathologic fractures, and debilitating deformities. Syphilis was believed to be the most common cause of Charcot arthropathy a century back, but now, it is one of the rare causes which get missed in the routine evaluation. We present a rare case of syphilitic Charcot joint in a middle aged, paraplegic, wheel-chaired bound male, who presented with a history of recurrent painless joint swelling.

Dynamical stability indicator based on autoregressive moving-average models: Critical transitions and the Atlantic meridional overturning circulation.

A statistical indicator for dynamic stability, known as the Υ indicator, is used to gauge the stability and, hence, detect approaching tipping points of simulation data from a reduced five-box model of the North Atlantic Meridional Overturning Circulation (AMOC) exposed to a time-dependent hosing function. The hosing function simulates the influx of fresh water due to the melting of the Greenland ice sheet and increased precipitation in the North Atlantic. The Υ indicator is designed to detect changes in the memory properties of the dynamics and is based on fitting auto-regressive moving-average models in a sliding window approach to time series data.

A neural circuit for flexible control of persistent behavioral states.

To adapt to their environments, animals must generate behaviors that are closely aligned to a rapidly changing sensory world. However, behavioral states such as foraging or courtship typically persist over long time scales to ensure proper execution. It remains unclear how neural circuits generate persistent behavioral states while maintaining the flexibility to select among alternative states when the sensory context changes.

COVID-19 ARDS: A Multispecialty Assessment of Challenges in Care, Review of Research, and Recommendations.

Physicians and care providers are familiar with the management of ARDS, however, when it occurs as a sequalae of COVID-19, it has different features and there remains uncertainty on the consensus of management. To answer this question on how it compares and contrasts with ARDS from other causes, the authors reviewed the published literature and management guidelines as well as their own clinical experience while managing patients with COVID-19 ARDS. For research, a PubMed search was conducted on 01.

Incidence of Renal Tract Abnormalities on Ultrasonography in Patients with Spinal Cord Injury: A Retrospective Pilot Study of a Military Cohort Undergoing Long-Term Institutional Rehabilitation.

Study Design: Retrospective pilot study.

Purpose: To assess the incidence of renal tract abnormalities using ultrasonography (US) in a military cohort with traumatic spinal cord injury (TSCI) at a tertiary level spinal cord injury center.

Overview Of Literature: Neurogenic bladder in TSCI patients results in significant urological morbidity.
