Understanding internal accountability in Nigeria’s routine immunization system: perspectives from government officials at the national, state, and local levels
BACKGROUND: Routine immunization coverage in Nigeria has remained low, and studies have identified a lack of accountability as a barrier to high performance in the immunization system. Accountability lies at the heart of various health systems strengthening efforts recently launched in Nigeria, including those related to immunization. Our aim was to understand the views of health officials on the accountability challenges hindering immunization service delivery at various levels of government.
METHODS: A semi-structured questionnaire was used to interview immunization and primary healthcare (PHC) officials from national, state, local, and health facility levels in Niger State in north central Nigeria. Individuals were selected to represent a range of roles and responsibilities in the immunization system. The questionnaire explored concepts related to internal accountability using a framework that organizes accountability into three axes based upon how they drive change in the health system.
RESULTS: Respondents highlighted accountability challenges across multiple components of the immunization system, including vaccine availability, financing, logistics, human resources, and data management. A major focus was the lack of clear roles and responsibilities both within institutions and between levels of government. Delays in funding, especially at lower levels of government, disrupted service delivery. Supervision occurred less frequently than necessary, and the limited decision space of managers prevented problems from being resolved. Motivation was affected by the inability of officials to fulfill their responsibilities. Officials posited numerous suggestions to improve accountability, including clarifying roles and responsibilities, ensuring timely release of funding, and formalizing processes for supervision, problem solving, and data reporting.
CONCLUSION: Weak accountability presents a significant barrier to performance of the routine immunization system and high immunization coverage in Nigeria. As one stakeholder in ensuring the performance of health systems, routine immunization officials reveal critical areas that need to be prioritized if emerging interventions to improve accountability in routine immunization are to have an effect

Dopamine Transporter Imaging in Psychogenic Parkinsonism and Neurodegenerative Parkinsonism with Psychogenic Overlay: A Report of Three Cases
Background: Differentiating psychogenic parkinsonism from neurodegenerative Parkinson's disease (PD) with psychogenic features is a diagnostic challenge.
Case report: We report a detailed longitudinal clinical description of three cases presenting with suspected psychogenic parkinsonism. Dopamine transporter single-photon emission computed tomography (DAT-SPECT) was used as a supplemental diagnostic study and influenced clinical management.
Discussion: DAT-SPECT quantified the integrity of the striatal dopaminergic system in these cases of clinically uncertain parkinsonism and supported clinical decision-making
Understanding Internal Accountability in Nigeria’s Routine Immunization System: Perspectives From Government Officials at the National, State, and Local Levels
Background: Routine immunization coverage in Nigeria has remained low, and studies have identified a lack of
accountability as a barrier to high performance in the immunization system. Accountability lies at the heart of various
health systems strengthening efforts recently launched in Nigeria, including those related to immunization. Our aim
was to understand the views of health officials on the accountability challenges hindering immunization service delivery
at various levels of government.
Methods: A semi-structured questionnaire was used to interview immunization and primary healthcare (PHC) officials
from national, state, local, and health facility levels in Niger State in north central Nigeria. Individuals were selected to
represent a range of roles and responsibilities in the immunization system. The questionnaire explored concepts related
to internal accountability using a framework that organizes accountability into three axes based upon how they drive
change in the health system.
Results: Respondents highlighted accountability challenges across multiple components of the immunization system,
including vaccine availability, financing, logistics, human resources, and data management. A major focus was the

Conclusion: Weak accountability presents a significant barrier to performance of the routine immunization system
and high immunization coverage in Nigeria. As one stakeholder in ensuring the performance of health systems,
routine immunization officials reveal critical areas that need to be prioritized if emerging interventions to improve
accountability in routine immunization are to have an effect

REM Sleep Behavior and Motor Findings in Parkinson’s Disease: A Cross-sectional Analysis
Background: Parkinson's disease (PD) represents a major public health challenge that will only grow in our aging population. Understanding the connection between PD and associated prodromal conditions, such as rapid eye movement sleep behavioral disorder (RBD), is critical to identifying prevention strategies. However, the relationship between RBD and severity of motor findings in early PD is unknown. This study aims to examine this relationship.
Methods: The study population consisted of 418 PD patients who completed the Movement Disorders Society‐United Parkinson's Disease Rating Scale (MDS‐UPDRS) and rapid eye movement sleep (REM) disorder questionnaires at the baseline visit of the Michael J. Fox's Parkinson's Progression Markers Initiative (PPMI). Cross‐sectional analysis was carried out to assess the association between REM Sleep Behavior Screening Questionnaire score and MDS UPDRS‐3 (motor) score categories. Correlation with a higher score category was described as “worse motor findings”. A score of 5 on the REM disorder questionnaire was defined as predictive of RBD.
Results: Out of the 418 PD patients, 113 (27.0%) had RBD. With univariate logistic regression analysis, individuals with scores predictive of RBD were 1.66 times more likely to have worse motor findings (p = 0.028). Even with age, gender, and Geriatric Depression Scale scores taken into account, individuals with scores predictive of RBD were 1.69 times more likely to have worse motor findings (p = 0.025).
Discussion: PD patients with RBD symptoms had worse motor findings than those unlikely to have RBD. This association provides further evidence for the relationship between RBD and PD
Clinicopathological Correlates in a PRNP P102L Mutation Carrier with Rapidly Progressing Parkinsonism-dystonia
Parkinsonism-dystonia is rare in carriers of PRNP P102L mutation. Severity and distribution of prion protein (PrP) deposition may influence the clinical presentation. We present such clinic-pathological correlation in a 56-year-old male with a PRNP P102L mutation associated with a phenotype characterized by rapidly progressing parkinsonism-dystonia. The patient was studied clinically (videotaped exams, brain MRIs); molecular genetically (gene sequence analysis); and neuropathologically (histology, immunohistochemistry) during his 7-month disease course. The patient had parkinsonism, apraxia, aphasia, and dystonia, which progressed rapidly. Molecular genetic analysis revealed PRNP P102L mutation carrier status. Brain MRIs revealed progressive global volume loss and T2/FLAIR hyperintensity in neocortex and basal ganglia. Postmortem examination showed neuronal loss, gliosis, spongiform changes, and PrP deposition in the striatum. PrP immunohistochemistry revealed widespread severe PrP deposition in the thalamus and cerebellar cortex. Based on the neuropathological and molecular-genetic analysis, the rapidly progressing parkinsonism-dystonia correlated with nigrostriatal, thalamic, and cerebellar pathology
No Sex Differences in Use of Dopaminergic Medication in Early Parkinson Disease in the US and Canada - Baseline Findings of a Multicenter Trial
Background: Sex differences in Parkinson disease clinical features have been reported, but few studies have examined sex influences on use of dopaminergic medication in early Parkinson disease. The objective of this study was to test if there are differences in the type of dopaminergic medication used and levodopa equivalent daily dose between men and women with early Parkinson disease enrolled in a large multicenter study of Creatine as a potential disease modifying therapy – the National Institute of Neurological Disorders and Stroke Exploratory Trials in Parkinson Disease Long-Term Study-1. Methods: Baseline data of 1,741 participants from 45 participating sites were analyzed. Participants from the United States and Canada were enrolled within five years of Parkinson Disease diagnosis. Two outcome variables were studied: type of dopaminergic medication used and levodopa equivalent daily dose at baseline in the Long-Term Study-1. Chi-square statistic and linear regression models were used for statistical analysis. Results: There were no statistically significant differences in the frequency of use of different types of dopaminergic medications at baseline between men and women with Parkinson Disease. A small but statistically significant difference was observed in the median unadjusted levodopa equivalent daily dose at baseline between women (300 mg) and men (325 mg), but this was not observed after controlling for disease duration (years since Parkinson disease diagnosis), disease severity (Unified Parkinson's Disease Rating Scale Motor and Activities of Daily Living Scores), and body weight. Conclusions: In this large multicenter study, we did not observe sex differences in the type and dose of dopaminergic medications used in early Parkinson Disease. Further research is needed to evaluate the influence of male or female sex on use of dopaminergic medication in mid- and late-stage Parkinson Disease
Sex Differences in Clinical Features of Early, Treated Parkinson\u27s Disease
INTRODUCTION: To improve our understanding of sex differences in the clinical characteristics of Parkinson\u27s Disease, we sought to examine differences in the clinical features and disease severity of men and women with early treated Parkinson\u27s Disease (PD) enrolled in a large-scale clinical trial.
METHODS: Analysis was performed of baseline data from the National Institutes of Health Exploratory Trials in Parkinson\u27s Disease (NET-PD) Long-term Study-1, a randomized, multi-center, double-blind, placebo-controlled study of 10 grams of oral creatine/day in individuals with early, treated PD. We compared mean age at symptom onset, age at PD diagnosis, and age at randomization between men and women using t-test statistics. Sex differences in clinical features were evaluated, including: symptoms at diagnosis (motor) and symptoms at randomization (motor, non-motor, and daily functioning).
RESULTS: 1,741 participants were enrolled (62.5% male). No differences were detected in mean age at PD onset, age at PD diagnosis, age at randomization, motor symptoms, or daily functioning between men and women. Differences in non-motor symptoms were observed, with women demonstrating better performance compared to men on SCOPA-COG (Z = 5.064, p\u3c0.0001) and Symbol Digit Modality measures (Z = 5.221, p\u3c0.0001).
CONCLUSIONS: Overall, men and women did not demonstrate differences in clinical motor features early in the course of PD. However, the differences observed in non-motor cognitive symptoms suggests further assessment of the influence of sex on non-motor symptoms in later stages of PD is warranted

Dual Treatment of Hemichorea-Hemiballismus Syndrome with Tetrabenazine and Chemodenervation
Background: Hemichorea–hemiballismus involves unilateral involuntary flailing movements and random jerking movements involving proximal or distal muscles. We describe a case of hemichorea–hemiballismus with dystonia after stroke. Treatment with tetrabenazine and chemodenervation produced beneficial responses. Effective treatment of both hemichorea–hemiballismus and dystonia due to stroke has not been reported. Case Report: A 65-year-old male developed left hemichorea–hemiballismus and dystonia after a right hemisphere stroke. He underwent initial treatment with neuroleptics and anticonvulsants without improvement. Subsequent treatment with tetrabenazine improved the hemichorea–hemiballismus and chemodenervation reduced the dystonia. Discussion: Hemichorea–hemiballismus associated with dystonia can be improved with both tetrabenazine and chemodenervation.</p
