Toward Correcting Anxious Movements Using Haptic Cues on the Da Vinci Surgical Robot.

Surgical movements have an important stylistic quality that individuals without formal surgical training can use to identify expertise. In our prior work, we sought to characterize quantitative metrics associated with surgical style and developed a near-real-time detection framework for stylistic deficiencies using a commercial haptic device. In this paper, we implement bimanual stylistic detection on the da Vinci Research Kit (dVRK) and focus on one stylistic deficiency, "Anxious", which may describe movements under stressful conditions.

COVID-19 in HIV: a Review of Published Case Reports.

Patients with COVID-19 present with a myriad of comorbidities. An immunocompromised state like HIV in patients with COVID-19 can be life-threatening. We searched PubMed/Medline, Scopus, and Web of Science for case reports and case series about COVID-19 in HIV patients.

Characterizing the Structural Integrity of Endotracheal Tube Taping Techniques: A Simulation Study.

Background: Endotracheal tubes (ETTs) are commonly secured with tape to prevent undesirable tube migration. Many methods of taping have been described, although little has been published comparing various methods of taping to one another. In this study, we evaluated several methods for securing ETTs with tape.

Meshy business: MRI and ultrasound evaluation of pelvic floor mesh and slings.

Pelvic floor disorders are a complex set of conditions including but not limited to stress urinary incontinence and pelvic organ prolapse that generally affect older and multiparous women. Of the several surgical options available for treatment of these conditions, synthetic mid-urethral slings for stress urinary incontinence and vaginal mesh for pelvic organ prolapse are amenable to imaging evaluation by ultrasound and magnetic resonance imaging techniques. Ultrasound can evaluate the sub- and immediate peri-urethral portions of sling due to its ability to differentiate synthetic material from native tissues with real-time imaging, while MRI is able to better depict the global pelvic floor anatomy and assess the more distant components of mesh and slings material.

Does 3DMR provide equivalent information as 3DCT for the pre-operative evaluation of adult Hip pain conditions of femoroacetabular impingement and Hip dysplasia?

Objective:: Femoroacetabular impingement (FAI) and hip dysplasia (HD) are frequently evaluated by isotropic CT (3DCT) for preoperative planning at the expense of radiation. The aim was to determine if isotropic MRI (3DMR) imaging can provide similar quantitative and qualitative morphological information as 3DCT.

Methods:: 25 consecutive patients with a final diagnosis of FAI or HD were retrospectively selected from December 2016-December 2017.

Management of pseudomeningocele following neurotologic procedures.

Objectives: A pseudomeningocele results from the escape of cerebrospinal fluid through a dural defect with trapping of subarachnoid fluid in surrounding soft tissue. The present study evaluates the incidence of pseudomeningocele following neurotologic procedures and delineates an algorithm for management.

Methods: A retrospective review of 375 consecutive patients undergoing neurotologic procedures at a single institution identified 17 patients with the postoperative complication of pseudomeningocele.

Characterization of a novel MICA allele, MICA*047.

We report the identification of a novel MICA allele, MICA*047. It was initially detected because of an unusual hybridization pattern with sequence-specific oligonucleotides (SSOP) in a normal subject of Caucasian origin. Cloning and sequencing of both strands, and comparison of the sequence with previously defined MICA alleles, revealed that the new allele is similar to MICA*041 except for one nucleotide substitution at position 811 (C-->G).
