Emergency Department Visits for Mild Traumatic Brain Injury: Associations with Geriatric Age, Sex, and Fall Injury.

PURPOSE: The highest rates mTBI occurrence are seen among geriatric populations (ages ≥65), and these patients often have persistent and untreated symptoms. This study's purpose was to explore mild traumatic brain injury initial onset (mTBI-IN) and mild traumatic brain injury subsequent (mTBI-S) emergency department (ED) visit population percentages and associations with geriatric (population ages ≥65), sex, and fall mechanism of injury. METHODS: The design was a population-based cross-sectional study using data from the 2018 Nationwide Emergency Department Sample (NEDS). Study sample size was 261,349. An independent t-test was used to investigate mean age differences between mTBI-IN and mTBI-S. Pearson's chi-squared correlational analyses were used to investigate associations of age, sex, and fall injury with mTBI-IN and mTBI-S. RESULTS: The mean age of those in 2018 with ED visits suggested that age was older for those patients with mTBI-S (age mean, 50.4 yrs) than those with mTBI-IN (age mean, 41.4 yrs) (95% CI 9.77, 8.30; p=0.025). The number of visits for those aged ≥65 was significantly associated with mTBI-S (p<0.001). More males than females reported mTBI-S ED visits in all ages (p=0.022). Falls injury alone was not found to be significantly associated with visits (p<0.001). CONCLUSIONS: Those returning to the ED for continued care after mTBI were associated with those aged ≥65. Monitoring after mTBI ED visits may need to target geriatric populations for medical management.

The national distribution of lymphatic filariasis cases in Malawi using patient mapping and geostatistical modelling.

BACKGROUND: In 2020 the World Health Organization (WHO) declared that Malawi had successfully eliminated lymphatic filariasis (LF) as a public health problem. Understanding clinical case distributions at a national and sub-national level is important, so essential care packages can be provided to individuals living with LF symptoms. This study aimed to develop a national database and map of LF clinical cases across Malawi using geostatistical modelling approaches, programme-identified clinical cases, antigenaemia prevalence and climate information. METHODOLOGY: LF clinical cases identified through programme house-to-house surveys across 90 sub-district administrative boundaries (Traditional Authority (TA)) and antigenaemia prevalence from 57 sampled villages in Malawi were used in a two-step geostatistical modelling process to predict LF clinical cases across all TAs of the country. First, we modelled antigenaemia prevalence in relation to climate covariates to predict nationwide antigenaemia prevalence. Second, we modelled clinical cases for unmapped TAs based on our antigenaemia prevalence spatial estimates. PRINCIPLE FINDINGS: The models estimated 20,938 (95% CrI 18,091 to 24,071) clinical cases in unmapped TAs (70.3%) in addition to the 8,856 (29.7%), programme-identified cases in mapped TAs. In total, the overall national number of LF clinical cases was estimated to be 29,794 (95% CrI 26,957 to 32,927). The antigenaemia prevalence and clinical case mapping and modelling found the highest burden of disease in Chikwawa and Nsanje districts in the Southern Region and Karonga district in the Northern Region of the country. CONCLUSIONS: The models presented in this study have facilitated the development of the first national LF clinical case database and map in Malawi, the first endemic country in sub-Saharan Africa. It highlights the value of using existing LF antigenaemia prevalence and clinical case data together with modelling approaches to produce estimates that may be used for the WHO dossier requirements, to help target limited resources and implement long-term health strategies.

Elimination of lymphatic filariasis as a public health problem in Malawi.

BACKGROUND: Lymphatic filariasis (LF) is a parasitic disease transmitted by mosquitoes, causing severe pain, disfiguring, and disabling clinical conditions such as lymphoedema and hydrocoele. LF is a global public health problem affecting 72 countries, primarily in Africa and Asia. Since 2000, the World Health Organization (WHO) has led the Global Programme to Eliminate Lymphatic Filariasis (GPELF) to support all endemic regions. This paper focuses on the achievements of the Malawi LF Elimination Programme between 2000 and 2020 to eliminate LF as a public health problem, making it the second sub-Saharan country to receive validation from the WHO. METHODOLOGY/PRINCIPAL FINDINGS: The Malawi LF Programme addressed the widespread prevalence of LF infection and disease across the country, using the recommended WHO GPELF strategies and operational research initiatives in collaboration with key national and international partners. First, to stop the spread of infection (i.e., interrupt transmission) and reduce the circulating filarial antigen prevalence from as high as 74.4% to below the critical threshold of 1-2% prevalence, mass drug administration (MDA) using a two-drug regime was implemented at high coverage rates (>65%) of the total population, with supplementary interventions from other programmes (e.g., malaria vector control). The decline in prevalence was monitored and confirmed over time using several impact assessment and post-treatment surveillance tools including the standard sentinel site, spot check, and transmission assessment surveys and alternative integrated, hotspot, and easy-access group surveys. Second, to alleviate suffering of the affected populations (i.e., control morbidity) the morbidity management and disability prevention (MMDP) package of care was implemented. Specifically, clinical case estimates were obtained via house-to-house patient searching activities; health personnel and patients were trained in self-care protocols for lymphoedema and/or referrals to hospitals for hydrocoele surgery; and the readiness and quality of treatment and services were assessed with new survey tools. CONCLUSIONS: Malawi's elimination of LF will ensure that future generations are not infected and suffer from the disfiguring and disabling disease. However, it will be critical that the Malawi LF Elimination programme remains vigilant, focussing on post-elimination surveillance and MMDP implementation and integration into routine health systems to support long-term sustainability and ongoing success. SUMMARY: Lymphatic filariasis, also known as elephantiasis, is a disabling, disfiguring, and painful disease caused by a parasite that infected mosquitoes transmit to millions of people worldwide. Since 2000, the Global Programme to Eliminate Lymphatic Filariasis (GPELF) has supported endemic countries such as Malawi in south-eastern Africa, to eliminate the disease as a public health problem. The Malawi National LF Elimination Programme has worked tirelessly over the past two decades to implement the GPELF recommended strategies to interrupt the transmission with a two-drug regime, and to alleviate suffering in patients with lymphoedema and/or hydrocoele through morbidity management and disability prevention. Additionally, the LF Programme has collaborated with national and international stakeholders to implement a range of supplementary operational research projects to address outstanding knowledge gaps and programmatic barriers. In 2020, the World Health Organisation validated that Malawi had successfully eliminated LF as a public health problem, making it the second country in sub-Saharan Africa to achieve this, which is remarkable given that Malawi previously had very high infection rates. The LF Programme now remains vigilant, putting its efforts towards post-elimination surveillance and the continued implementation of care for patients with chronic conditions. Malawi's elimination of LF will ensure that future generations are not affected by this devastating disease.

Mental health conditions in people affected by filarial lymphoedema in Malawi: prevalence, associated risk factors and the impact of an enhanced self-care intervention.

BACKGROUND: This study aimed to determine the key mental health indicators affecting people affected by lymphatic filariasis (LF) lymphoedema by assessing the prevalence of depressive symptoms and quality of life (QOL), identifying associated sociodemographic and clinical risk factors, and evaluating the impact of an enhanced self-care intervention for lymphoedema management. METHODS: A prospective cohort study of adults with filarial lymphoedema from two regions of Malawi was conducted over six months in 2021. Depressive symptoms and QOL were assessed using Patient Health Questionnaire (PHQ-9) and LF Specific QOL Questionnaire, respectively, at baseline (pre-intervention), 3- and 6-months (postintervention). Beta regression analysis identified risk factors, and assessed the impact of the intervention. RESULTS: Three hundred eleven affected individuals were surveyed with 23% (95% CI 18%-29%) reporting mild/moderate depressive symptoms and 31% (95% CI 26%-37%) reporting moderately low/low QOL. Higher depressive symptom scores were associated with high frequency of acute filarial attack episodes. Individuals with higher depressive symptoms (Adjusted Odds Ratios (AOR) 0.93, 95% CI 0.93-0.93) and lower QOL (AOR 0.98, 0.98-0.98) showed greatest improvement in mental health indicators over 3-months but was not sustained to the same level at 6-months. CONCLUSIONS: Sustained morbidity management and psychological support is recommended for affected persons to ensure long-term positive mental health and clinical outcomes. CONTEXTE: Cette étude vise à déterminer les principaux indicateurs de santé mentale affectant les personnes atteintes de lymphœdème dû à la filariose lymphatique (FL) en évaluant la prévalence des symptômes dépressifs et la qualité de vie (QV), en identifiant les facteurs de risque sociodémographiques et cliniques associés, et en évaluant l'impact d'une intervention améliorée d'autosoins pour la gestion du lymphœdème. MÉTHODES: Une étude de cohorte prospective d'adultes atteints de lymphoedème filaire dans deux régions du Malawi a été menée pendant six mois en 2021. Les symptômes dépressifs et la qualité de vie ont été évalués à l'aide du questionnaire sur la santé des patients (PHQ-9) et du questionnaire sur la qualité de vie spécifique au lymphœdème, respectivement, au début de l'étude (avant l'intervention), et à 3 puis 6 mois après l'intervention. Une analyse de régression beta a permis d'identifier les facteurs de risque et d'évaluer l'impact de l'intervention. RÉSULTATS: Trois cent onze personnes affectées ont été interrogées, dont 23% (95% CI 18%-29%) ont déclaré des symptômes dépressifs légers/modérés et 31% (95% CI 26%-37%) ont déclaré une qualité de vie modérément faible/faible. Des scores élevés de symptômes dépressifs ont été associés à une fréquence élevée d'épisodes de crises filariennes aiguës. Les personnes présentant des symptômes dépressifs plus élevés (rapport de cotes ajusté (RCA) 0.93, IC à 95 % 0.93-0.93) et une qualité de vie plus faible (RCA 0.98, 0.98-0.98) ont montré la plus grande amélioration des indicateurs de santé mentale au cours des trois mois, mais cette amélioration ne s'est pas maintenue au même niveau au cours des six mois suivants. CONCLUSION: Gestion de la morbidité et soutien psychologique sont des éléments clés pour garantir une santé mentale et des résultats cliniques satisfaisants de personnes atteintes sur le long terme. ANTECEDENTES: Este estudio tuvo como objetivo determinar los indicadores clave de salud mental que afectan a las personas afectadas por linfedema por filariasis linfática (FL) mediante la evaluación de la prevalencia de síntomas depresivos y calidad de vida (CdV), la identificación de factores de riesgo sociodemográficos y clínicos asociados, y la evaluación del impacto de una intervención de autocuidado mejorada para el manejo del linfedema. MÉTODOS: Se realizó un estudio prospectivo de cohortes de adultos con linfedema filarial de dos regiones de Malawi durante seis meses en 2021. Los síntomas depresivos y la calidad de vida se evaluaron mediante el Cuestionario de Salud del Paciente (PHQ-9) y el Cuestionario de Calidad de Vida específico para el LF Cuestionario, respectivamente, al inicio (preintervención) y a los 3 y 6 meses (posintervención). El análisis de regresión beta identificó los factores de riesgo y evaluó el impacto de la intervención. RESULTADOS: Se encuestó a 311 afectados, de los cuales el 23% (IC 95%, 18%-29%) presentaba síntomas depresivos leves/moderados y el 31% (IC 95%, 26%-37%) una CdV moderadamente baja/baja CdV. Las puntuaciones más altas de síntomas depresivos se asociaron con una alta frecuencia de episodios de ataques agudos de filarias. Los individuos con mayores síntomas depresivos (Odds Ratios Ajustados [ORA] 0.93; IC 95%: 0.93-0.93) y menor CdV (ORA 0.98; 0.98-0.98) mostraron la mayor mejoría en los indicadores de salud mental a los 3 meses, pero no se mantuvo al mismo nivel a los 6 meses. CONCLUSIONES: Se recomienda el manejo sostenido de la morbilidad y el apoyo psicológico a las personas afectadas para garantizar resultados clínicos y de salud mental positivos a largo plazo.

Differential screen and treatment of vestibular dysfunction in an elderly patient: A case report.

BACKGROUND/PURPOSE: Concussion sequelae in the elderly is under recognized and negatively impacts quality of life. Labyrinthine concussion (LC) is an uncommon diagnosis, as is multiple canal (MC) benign paroxysmal positional vertigo (BPPV). This case report highlights physical therapist (PT) evaluation and treatment of an elderly male misdiagnosed with LC and successfully treated for MC BPPV. CASE DESCRIPTION: A 72 year old male presented to his PT 23 days after falling off a ladder, resulting in a mild traumatic brain injury (mTBI). Diagnosed with LC, he was referred to PT due to ongoing symptoms of "falling backwards," poor gait, and diminished mobility. PT examination revealed an atypical BPPV. Thus, the patient was treated in two PT visits, which included canalith repositioning techniques and neuromuscular reeducation. OUTCOMES: The PT diagnosis was MC BPPV, including the right lateral and left posterior semicircular canals. Initial positive findings of Head Impulse Test, Bow and Lean Test, Dix-Hallpike, and Roll Test were negative on the last visit. Patient-Specific Functional Scale improved from 0 to 9.9 (10 being no limitations). The patient progressed from minimum assistance to independence in bed mobility, transfers, gait, and previous activities. DISCUSSION: The patient's presentation was atypical in signs and symptoms with a diagnosis of LC. PT examination and intervention successfully resolved the patient's signs and symptoms within two visits. Further research is needed regarding identification and treatment of elderly individuals with head injuries, such as MC BPPV, as well as the efficacy of a PT seeing patients shortly after mTBI.

Successful Management of Severe Unilateral Lower Extremity Lymphedema in an Outpatient Setting.

BACKGROUND AND PURPOSE: Non-cancer-related lymphedema is frequently unrecognized until it has advanced and, therefore, presents substantial management challenges. Treatment for lymphedema reflects cancer research and not the distinct complexities of non-cancer-related lymphedema. This case report describes an outpatient intervention for a patient with non-cancer-related unilateral lower extremity lymphedema. CASE DESCRIPTION: The patient was a 42-year-old woman who was morbidly obese and had left lower extremity chronic stage III lymphedema. Massive disfiguring lymphedema of her lower leg caused chronic wounds, pain, difficulty ambulating, and the inability to lift her leg in transfers. The patient received complete decongestive therapy (CDT) in an outpatient setting. OUTCOMES: The volume of the patient's leg decreased more than 66%, so that her massive lower leg was transformed to nearly the same size as her unaffected limb. Proper compression management restored independent transfers and pain-free ambulation. DISCUSSION: Delayed diagnosis and treatment of non-cancer-related lymphedema result in increased severity and impaired mobility, making this a unique, complex condition requiring modifications to CDT in the outpatient setting. This case report demonstrates successful outpatient treatment of a patient with severe unilateral lower extremity lymphedema associated with large wounds and impaired mobility using CDT that was modified to accommodate her complex medical status, transportation barriers, and health insurance availability. Following 23 weeks of physical therapist interventions, the patient's affected lower extremity was the same size as the unaffected lower extremity, and she was independent in ambulation and stair climbing.
