Remote assessment of the Penn computerised neurocognitive battery in individuals with 22q11.2 deletion syndrome

BACKGROUND

Neurocognitive functioning is an integral phenotype of 22q11.2 deletion syndrome relating to severity of psychopathology and outcomes. A neurocognitive battery that could be administered remotely to assess multiple cognitive domains would be especially beneficial to research on rare genetic variants, where in-person assessment can be unavailable or burdensome. The current study compares in-person and remote assessments of the Penn computerised neurocognitive battery (CNB).

METHODS

Participants (mean age = 17.82, SD = 6.94 years; 48% female) completed the CNB either in-person at a laboratory (n = 222) or remotely (n = 162).

RESULTS

Results show that accuracy of CNB performance was equivalent across the two testing locations, while slight differences in speed were detected in 3 of the 11 tasks.

CONCLUSIONS

These findings suggest that the CNB can be used in remote settings to assess multiple neurocognitive domains.

Gathering the Stakeholder's Perspective: Experiences and Opportunities in Rare Genetic Disease Research

BACKGROUND

Research participant feedback is rarely collected; therefore, investigators have limited understanding regarding stakeholders' (affected individuals/caregivers) motivation to participate. Members of the Genes to Mental Health Network (G2MH) surveyed stakeholders affected by copy number variants (CNVs) regarding perceived incentives for study participation, opinions concerning research priorities, and the necessity for future funding. Respondents were also asked about feelings of preparedness, research burden, and satisfaction with research study participation.

METHODS

Modified validated surveys were used to assess stakeholders´ views across three domains: (1) Research Study Enrollment, Retainment, Withdrawal, and Future Participation; (2) Overall Research Experience, Burden, and Preparedness; (3) Research Priorities and Obstacles. Top box score analyses were performed.

RESULTS

A total of 704 stakeholders´ responded from 29 countries representing 55 CNVs. The top reasons for initial participation in the research included reasons related to education and altruism. The top reasons for leaving a research study included treatment risks and side effects. The importance of sharing research findings and laboratory results with stakeholders was underscored by participants. Most stakeholders reported positive research experiences.

CONCLUSIONS

This study provides important insight into how individuals and families affected with a rare CNV feel toward research participation and their overall experience in rare disease research. There are clear targets for areas of improvement for study teams, although many stakeholders reported positive research experiences. Key findings from this international survey may help advance collaborative research and improve the experience of participants, investigators, and other stakeholders moving forward.

Relationship between surgically induced neuropathy and outcome of pelvic organ prolapse surgery

The aim of the study was to determine whether surgically induced perineal neuropathy relates to the outcome of surgery for the correction of pelvic organ prolapse. Perineal nerve terminal motor latencies (PeNTML) were obtained in 31 women prior to and following transvaginal surgery for the correction of pelvic organ prolapse consisting of bilateral sacrospinous ligament vault suspension and bilateral paravaginal cystocele repair. Mean follow-up was 32 months (range 12-60). Surgical outcome was defined as optimal (asymptomatic, with the apex of the vagina above the levator plate with no tissue protruding beyond the hymen in the upright position with maximum Valsalva), or suboptimal (apical descent of > 50%, or any vaginal wall protrusion beyond the hymen in the upright position with maximum Valsalva). Surgically induced neuropathy was defined as an increase of 0.6 ms or more in the averaged right and left PeNTML measurements following the surgery. All women had preoperative symptomatic prolapse and the mean preoperative PeNTML was prolonged compared to established normals. Using strict definitions, 11 women had optimal outcome and 20 had suboptimal outcome. The outcome groups were similar with respect to age, weight, parity, degree of preoperative prolapse and preoperative perineal neuropathy. Eleven women had surgically induced perineal neuropathy. This was associated with suboptimal outcome compared to optimal outcome (P = 0.03). The relative risk of suboptimal outcome with surgically induced neuropathy was 1.82 (95% CI 1.13-2.93). It was concluded that a relationship exists between the outcome of organ prolapse surgery and surgically induced perineal neuropathy as measured by PeNTML. Such neuropathy may play a role in failed pelvic reconstructive surgery.
