Follow-up observation of eye movements in multiple system atrophy and Parkinsons disease: a cohort study

Objectives
We aimed to explore the changes in oculomotor deficiencies during the follow-up of patients with multiple system atrophy (MSA) and Parkinson’s disease (PD), and to investigate the value of dynamic eye movement examination in their differential diagnosis.

Design
This was a cohort study conducted from 2017 to 2023.

Setting
The Movement Disorders Clinic at a tertiary hospital in Beijing, China.

Participants
56 patients with PD and 13 patients with MSA from an initial cohort of over 1100 with parkinsonism were included in the final longitudinal analysis.

Outcome measures
Multisystem evaluations were performed at baseline. Videonystagmography (VNG) was repeated to assess oculomotor dysfunction at baseline and during follow-up. Abnormalities in the fixation and gaze-holding test, without-fixation test, reflexive and memory-guided saccade tests, smooth pursuit test and optokinetic test were qualitatively and quantitatively recorded and statistically analysed.

Results
The median follow-up time of MSA (16 months) was significantly shorter than that of PD (27 months). In MSA, the incidence of abnormalities in fixation and gaze-holding tests (0% vs 30.8%, p=0.030), reflexive saccade tests (46.2% vs 84.6%, p=0.039, with slow saccades increasing from 7.7% to 46.2%, p=0.027) and smooth pursuit tests (38.5% vs 76.9%, p=0.047) increased significantly from baseline to the end of follow-up. In PD, no significant changes were revealed during follow-up.

Conclusions
MSA exhibited more rapid and prominent changes in fixation and gaze-holding tests, reflexive saccades and smooth pursuit tests than PD. Dynamic observation of oculomotor function may aid in the differential diagnosis of Parkinson’s syndrome.

Qualitative study on postbariatric surgery follow-up in France: a new patient-physician relationship

Background
Most studies on bariatric patients to date have only examined mortality and morbidities in terms of surgery or no surgery. Few have investigated loss to follow-up in post-surgery patients.

Purpose
This study aimed to describe the dynamics behind non-adherence to follow-up in bariatric patients postsurgery.

Design
Using semi-structured interviews, we performed a qualitative study. Using a thematic analysis, we described themes involved in patient adherence to postsurgery follow-up.

Setting
Participants were recruited from a university hospital near Paris and via social networks.

Participants
17 patients who had undergone surgery, some of whom were lost to follow-up, 15 women and 2 men, were interviewed, during a mean time of 90 min. 10 were adherent, and 7 were lost to follow-up.

Results
Follow-up was seen as a support in which the care provider–patient relationship can act on the four following themes: (1) regaining control, (2) knowledge acquisition, (3) management of fears and (4) overall restructuring of one’s life postsurgery.

Conclusions
Patients’ experiences and representations of postsurgery follow-up should be documented in detail in order to define the specific roles of the various care providers offering support to this population, and to strengthen the coordination of care pathways between these actors. In addition, improving the quality of communication could improve adherence to follow-up after bariatric surgery.

What drives clinic follow-up after traumatic spinal injury? An observational cohort study from Tanzania

Objectives
To evaluate factors associated with clinic follow-up after traumatic spinal injury (TSI) in Tanzania, focusing on demographic, injury-related and hospital variables. We hypothesised that socioeconomic and injury-specific factors would predict follow-up adherence.

Design
Retrospective observational cohort study.

Setting
Tertiary government referral centre for neurosurgery and orthopaedics in Dar es Salaam, Tanzania.

Participants
443 adults with TSI admitted between September 2016 and October 2021. Inclusion criteria included survival to discharge and availability of the discharge date. Patients with missing data were excluded.

Primary and secondary outcome measures
Primary outcomes were any clinic follow-up and 1-year follow-up post-discharge. Secondary outcome was time to loss of follow-up. Logistic regression was used to identify factors associated with follow-up, and Kaplan-Meier survival analysis assessed follow-up duration.

Results
Of 443 patients (85.8% male, median age 34 years), 52.4% returned for follow-up. Independent factors associated with return included private insurance (adjusted OR (aOR) 2.69, 95% CI 1.38 to 5.45, p=0.005), involvement in a road traffic accident (aOR 2.15, 95% CI 1.22 to 3.83, p=0.009), lumbar injuries (aOR 2.26, 95% CI 1.30 to 4.00, p=0.004), neurological improvement at discharge (aOR 3.52, 95% CI 1.72 to 7.64, p=0.001) and hospital stays shorter than 24 days (aOR 1.63, 95% CI 1.07 to 2.47, p=0.022). Among those who returned, only 25.4% completed 1 year of follow-up. Predictors of 1-year follow-up included being female (aOR 4.87, 95% CI 2.31 to 10.56, p
