Impact of population based indoor residual spraying with and without mass drug administration with dihydroartemisinin-piperaquine on malaria prevalence in a high transmission setting: a quasi-experimental controlled before-and-after trial in northeastern Uganda.

BACKGROUND: Declines in malaria burden in Uganda have slowed. Modelling predicts that indoor residual spraying (IRS) and mass drug administration (MDA), when co-timed, have synergistic impact. This study investigated additional protective impact of population-based MDA on malaria prevalence, if any, when added to IRS, as compared with IRS alone and with standard of care (SOC). METHODS: The 32-month quasi-experimental controlled before-and-after trial enrolled an open cohort of residents (46,765 individuals, 1st enumeration and 52,133, 4th enumeration) of Katakwi District in northeastern Uganda. Consented participants were assigned to three arms based on residential subcounty at study start: MDA+IRS, IRS, SOC. IRS with pirimiphos methyl and MDA with dihydroartemisinin- piperaquine were delivered in 4 co-timed campaign-style rounds 8 months apart. The primary endpoint was population prevalence of malaria, estimated by 6 cross-sectional surveys, starting at baseline and preceding each subsequent round. RESULTS: Comparing malaria prevalence in MDA+IRS and IRS only arms over all 6 surveys (intention-to-treat analysis), roughly every 6 months post-interventions, a geostatistical model found a significant additional 15.5% (95% confidence interval (CI): [13.7%, 17.5%], Z = 9.6, p = 5e-20) decrease in the adjusted odds ratio (aOR) due to MDA for all ages, a 13.3% reduction in under 5's (95% CI: [10.5%, 16.8%], Z = 4.02, p = 5e-5), and a 10.1% reduction in children 5-15 (95% CI: [8.5%, 11.8%], Z = 4.7, p = 2e-5). All ages residents of the MDA + IRS arm enjoyed an overall 80.1% reduction (95% CI: [80.0%, 83.0%], p = 0.0001) in odds of qPCR confirmed malaria compared with SOC residents. Secondary difference-in-difference analyses comparing surveys at different timepoints to baseline showed aOR (MDA + IRS vs IRS) of qPCR positivity between 0.28 and 0.66 (p < 0.001). Of three serious adverse events, one (nonfatal) was considered related to study medications. Limitations include the initial non-random assignment of study arms, the single large cluster per arm, and the lack of an MDA-only arm, considered to violate equipoise. CONCLUSIONS: Despite being assessed at long time points 5-7 months post-round, MDA plus IRS provided significant additional protection from malaria infection over IRS alone. Randomized trials of MDA in large areas undergoing IRS recommended as well as cohort studies of impact on incidence. TRIAL REGISTRATION: This trial was retrospectively registered 11/07/2018 with the Pan African Clinical Trials Registry (PACTR201807166695568).

Patterns of amygdala region pathology in LATE-NC: subtypes that differ with regard to TDP-43 histopathology, genetic risk factors, and comorbid pathologies.

Transactive response (TAR) DNA-binding protein 43 kDa (TDP-43) pathology is a hallmark of limbic-predominant age-related TDP-43 encephalopathy (LATE). The amygdala is affected early in the evolution of LATE neuropathologic change (LATE-NC), and heterogeneity of LATE-NC in amygdala has previously been observed. However, much remains to be learned about how LATE-NC originates and progresses in the brain. To address this, we assessed TDP-43 and other pathologies in the amygdala region of 184 autopsied subjects (median age = 85 years), blinded to clinical diagnoses, other neuropathologic diagnoses, and risk genotype information. As previously described, LATE-NC was associated with older age at death, cognitive impairment, and the TMEM106B risk allele. Pathologically, LATE-NC was associated with comorbid hippocampal sclerosis (HS), myelin loss, and vascular disease in white matter (WM). Unbiased hierarchical clustering of TDP-43 inclusion morphologies revealed discernable subtypes of LATE-NC with distinct clinical, genetic, and pathologic associations. The most common patterns were: Pattern 1, with lamina II TDP-43 + processes and preinclusion pathology in cortices of the amygdala region, and frequent LATE-NC Stage 3 with HS; Pattern 2, previously described as type-ß, with neurofibrillary tangle-like TDP-43 neuronal cytoplasmic inclusions (NCIs), high Alzheimer's disease neuropathologic change (ADNC), frequent APOE ε4, and usually LATE-NC Stage 2; Pattern 3, with round NCIs and thick neurites in amygdala, younger age at death, and often comorbid Lewy body disease; and Pattern 4 (the most common pattern), with tortuous TDP-43 processes in subpial and WM regions, low ADNC, rare HS, and lower dementia probability. TDP-43 pathology with features of patterns 1 and 2 were often comorbid in the same brains. Early and mild TDP-43 pathology was often best described to be localized in the "amygdala region" rather than the amygdala proper. There were also important shared attributes across patterns. For example, all four patterns were associated with the TMEM106B risk allele. Each pattern also demonstrated the potential to progress to higher LATE-NC stages with confluent anatomical and pathological patterns, and to contribute to dementia. Although LATE-NC showed distinct patterns of initiation in amygdala region, there was also apparent shared genetic risk and convergent pathways of clinico-pathological evolution.

Exploring a collaborative approach to the involvement of patients, carers and the public in the initial education and training of healthcare professionals: A qualitative study of patient experiences.

OBJECTIVE: This study aimed to explore patients' experiences of their involvement in the design and delivery of interprofessional education interventions focussing on mental ill-health for students studying in undergraduate healthcare and healthcare-related programmes. DESIGN: A qualitative methodology using a Grounded Theory approach was used to undertake an iterative series of focus groups with members of a university's Patient, Carer and Public Involvement (PCPI) Group who have a history of mental ill-health and were involved in the development and delivery of educational interventions for students on undergraduate healthcare and healthcare-related programmes. Their experiences of being involved in teaching and learning activities, collaboration with academic staff and integration into the academic faculty were explored. Constant comparative analysis facilitated the identification and prioritisation of salient themes. RESULTS: Five salient inter-related themes emerged from the data: (1) reduced stigma and normalisation of experience of illness; (2) enhanced self-worth; (3) improved well-being; (4) community and connection; and (5) enduring benefits. CONCLUSIONS: A supportive university community and a designated academic PCPI co-ordinator facilitate a supportive environment for patients and carers to develop as educators, contribute to the training of future healthcare professionals and improve their own personal well-being. Appropriately resourced and well-supported initiatives to integrate patients, carers and the public into the functions of an academic faculty can result in tangible benefits to individuals and facilitate meaningful and enduring connections between the university and the wider community within which it is situated. PATIENT AND PUBLIC INVOLVEMENT: Patients have been involved in the design of the teaching and learning initiatives that this study was primarily focused on. Patients were given autonomy in determining how their experiences should be incorporated into teaching and learning experiences.

Stability testing of dried Plasmodium falciparum positive quality control samples for malaria rapid diagnostic tests in Liberia and Benin.

BACKGROUND: Malaria rapid diagnostic tests (RDTs) are largely responsible for the gains made in the proportion of malaria cases confirmed with a parasitological test. However, quality assurance programs to support their use remain a challenge. A dried tube specimen (DTS) method was developed that showed potential for use as a stable source of quality control (QC) sample for RDTs and for use in external quality assessments or proficiency testing (PT). DTS was further assessed with focus on sample stability under field settings in Benin and Liberia. METHODS: DTS were prepared using Plasmodium falciparum 3D7 or W2 strains at concentrations of 1000, 500 or 0 parasites/µL and tested for baseline reactivity at the Centers for Disease Control and Prevention, Atlanta before shipping. In Benin and Liberia, DTS were stored under refrigeration in a reference laboratory (RL) or in health centres under ambient temperatures. Seven rounds of testing were performed at 4-week intervals during which DTS were tested on RDTs stored at the RL or at health centres. Observed DTS reactivity at the RL and health centres were compared to expected reactivity to determine DTS stability. DTS were also assembled into a PT panel and tested by health facility staff at the mid and end time-points of the study. Daily maximum and minimum storage temperatures for RDTs and DTS were recorded. RESULTS: In Benin, DTS, irrespective of storage conditions, produced the expected reactivity at all time points. However, evidence of degradation was observed at weeks 20 and 24 for DTS stored at ambient temperatures at the health centres and not those stored under refrigeration at the RL. In Liberia, sample degradation was observed starting at week 8 especially among DTS stored at the health facilities. The degradation was associated with prolonged storage of DTS under ambient temperature prior to study commencement and less than optimal storage temperatures at the RL. Use of DTS in a PT enabled identification of health worker errors in performing the tests. CONCLUSION: DTS is a feasible tool for use as QC material and for PT under field conditions. Long-term (> 5 months) storage of DTS requires refrigeration.

ATRX protein loss and deregulation of PI3K/AKT pathway is frequent in pilocytic astrocytoma with anaplastic features.

INTRODUCTION: Pilocytic astrocytoma (PA) with anaplastic features (PAAF) is a rare entity associated with decreased survival. It is characterized by hypercellularity, atypia, brisk mitotic activity, variable necrosis, and association with a classic PA component or anaplastic transformation in a recurrent tumor with a previously-documented classic PA. MATERIALS AND METHODS: We present 5 PAAF cases with clinical, radiological, pathological, and molecular correlation. We interrogated ATRX, IDH, TP53, PTEN, EGFR, BRAF, 6q23, p16(Ink4a) by sequencing, FISH, and immunohistochemistry. RESULTS: Four tumors were located in the cerebellum, and 1 was supratentorial. All showed ATRX protein loss by immunohistochemistry, loss of heterozygosity for PTEN, and had no IDH/TP53/BRAF mutations, nor EGFR amplification. Two of 5 tumors showed BRAF duplication by pyrosequencing. All showed loss of PTEN nuclear expression in subsets of tumor cells, which was associated with variable cytoplasmic positivity for pS6. There was a relative correlation between loss of PTEN expression and pS6 cytoplasmic expression. p53 was expressed in ~ 50% of tumor cells in all tumors. P16 was variably lost in all cases. One tumor showed MYB/6q23 deletion. CONCLUSION: We confirm ATRX protein loss suggestive of ATRX alteration as well as dysregulation of the PI3K/AKT pathway and, less often, of the MAPK/ERK pathway in PAAF.

Third Nerve Palsy as the Presenting Sign of Metastatic Endometrial Carcinoma with Lymphovascular Space Invasion.

We present a case of endometrial carcinoma (EC) presenting with a third cranial nerve palsy due to metastasis to the cavernous sinus. Although the tumour was only stage 1B, histopathologic features including higher grade and lymphovascular space invasion (LVSI) increase the risk of recurrent and metastatic disease. To our knowledge, this is the first case of EC presenting as a third cranial nerve palsy in the English-language ophthalmic literature. Clinicians should be aware that the risk of metastatic EC including neuro-ophthalmic presentations depends upon not only stage and grade but also the presence of unique histopathological findings such as LVSI.

Supraorbital Nerve and Cavernous Sinus Invasion with Poorly Differentiated Carcinoma of Unknown Primary.

A 50-year-old man presented with a 4-month history of right-sided trigeminal neuropathy in the V1 and V2 distribution, right sixth nerve palsy and Horner syndrome. Magnetic resonance imaging (MRI) showed enhancement and thickening along the right ophthalmic nerve and supraorbital nerve and fullness at the right cavernous sinus extending to Meckel's cave. Evaluation for a primary tumour was negative. Cavernous sinus biopsy showed infiltrating poorly differentiated carcinoma; the patient underwent radiation therapy. To our knowledge this is the only case of poorly differentiated carcinoma involving the supraorbital nerve presenting with trigeminal neuropathy and Horner syndrome in the English ophthalmic literature.

Expanding the spectrum of neuronal pathology in multiple system atrophy.

Multiple system atrophy is a sporadic alpha-synucleinopathy that typically affects patients in their sixth decade of life and beyond. The defining clinical features of the disease include progressive autonomic failure, parkinsonism, and cerebellar ataxia leading to significant disability. Pathologically, multiple system atrophy is characterized by glial cytoplasmic inclusions containing filamentous alpha-synuclein. Neuronal inclusions also have been reported but remain less well defined. This study aimed to further define the spectrum of neuronal pathology in 35 patients with multiple system atrophy (20 male, 15 female; mean age at death 64.7 years; median disease duration 6.5 years, range 2.2 to 15.6 years). The morphologic type, topography, and frequencies of neuronal inclusions, including globular cytoplasmic (Lewy body-like) neuronal inclusions, were determined across a wide spectrum of brain regions. A correlation matrix of pathologic severity also was calculated between distinct anatomic regions of involvement (striatum, substantia nigra, olivary and pontine nuclei, hippocampus, forebrain and thalamus, anterior cingulate and neocortex, and white matter of cerebrum, cerebellum, and corpus callosum). The major finding was the identification of widespread neuronal inclusions in the majority of patients, not only in typical disease-associated regions (striatum, substantia nigra), but also within anterior cingulate cortex, amygdala, entorhinal cortex, basal forebrain and hypothalamus. Neuronal inclusion pathology appeared to follow a hierarchy of region-specific susceptibility, independent of the clinical phenotype, and the severity of pathology was duration-dependent. Neuronal inclusions also were identified in regions not previously implicated in the disease, such as within cerebellar roof nuclei. Lewy body-like inclusions in multiple system atrophy followed the stepwise anatomic progression of Lewy body-spectrum disease inclusion pathology in 25.7% of patients with multiple system atrophy, including a patient with visual hallucinations. Further, the presence of Lewy body-like inclusions in neocortex, but not hippocampal alpha-synuclein pathology, was associated with cognitive impairment (P = 0.002). However, several cases had the presence of isolated Lewy body-like inclusions at atypical sites (e.g. thalamus, deep cerebellar nuclei) that are not typical for Lewy body-spectrum disease. Finally, interregional correlations (rho ≥ 0.6) in pathologic glial and neuronal lesion burden suggest shared mechanisms of disease progression between both discrete anatomic regions (e.g. basal forebrain and hippocampus) and cell types (neuronal and glial inclusions in frontal cortex and white matter, respectively). These findings suggest that in addition to glial inclusions, neuronal pathology plays an important role in the developmental and progression of multiple system atrophy.

Epithelial and organ-related marker expression in pituitary adenomas.

The histologic expression of epithelial and organ-related immunohistochemical markers in primary sellar region tumors has received little attention to date. This lack of empirical data may lead to mistaken assumptions in the evaluation of sellar region neoplasms. To address this issue, the frequency and specificity of epithelial (cytokeratin 7(CK7), CK20) and organ-related differentiation markers (gross cystic disease fluid protein-15 (GCDFP-15), thyroid transcription factor-1 (TTF-1), Napsin A, paired box 8 (PAX-8), hepatocyte paraffin 1 (HepPar1) and estrogen receptor (ER)) were studied in 40 patients with adenomas comprising five hormonal sub-types. Non-parametric statistical procedures were used to examine associations between marker expression and tumor sub-type. CK7 and CK20 immunoreactivity were seen in 48% and 8% of tumors, respectively, although never in a diffuse pattern. CK20 expression was nearly exclusive to corticotrophs, whereas CK7 frequently highlighted cells with dendritic-type morphology. The specificity of organ-related differentiation markers was 100% (monoclonal Napsin A, GCDFP-15 and TTF-1), 97% (HepPar1 and PAX-8), 90% (polyclonal Napsin A) and 72% (ER); no tumors demonstrated significant co-expression of these organ-related markers with either CK7 or CK20. The first major conclusion of this study is that CK7 staining in adenoma is more frequent than has been previously than has been previously described. CK7 immunoreactive cells often displayed a dendritic-type morphology, including within large macroadenomas, which raises the question as to whether these represent tumor cells with folliculo-stellate cell-type differentiation, as these also have dendritic cell-type morphology and express CK7 in non-neoplastic glands. The second major conclusion, which confirms earlier findings, is that CK20 staining is a very infrequent immunohistochemical finding in adenomas that is virtually limited to corticotrophs and thus is helpful in diagnostic confirmation of that sub-type. The final conclusion is in regard to those features that separate adenomas from sellar region metastases: adenomas do not demonstrate significant expression of TTF-1, monoclonal Napsin A, PAX-8, HepPar1 or GCDFP-15, nor do they exhibit diffuse expression of CK7 and CK20.

Suprasellar Primitive Neuroectodermal Tumor in an Adult.

Primitive neuroectodermal tumors (PNET) of the central nervous system (CNS) are a heterogeneous group of embryonal malignancies that are composed of undifferentiated or poorly differentiated neuroepithelial cells. Supratentorial PNET is the second most common CNS embryonal malignancy in children, but it is rare in adults. We report the case of a 31-year-old woman with bilateral vision loss and a bitemporal hemianopia. Neuroimaging revealed a suprasellar mass, and pathology was consistent with PNET. After surgical debulking of the tumor followed by radiation therapy and chemotherapy, the patient had significant visual recovery and remained stable over 14 months of follow-up.

Monitoring Effect of Human Papillomavirus Vaccines in US Population, Emerging Infections Program, 2008-2012.

In 2007, five Emerging Infections Program (EIP) sites were funded to determine the feasibility of establishing a population-based surveillance system for monitoring the effect of human papillomavirus (HPV) vaccine on pre-invasive cervical lesions. The project involved active population-based surveillance of cervical intraepithelial neoplasia grades 2 and 3 and adenocarcinoma in situ as well as associated HPV types in women >18 years of age residing in defined catchment areas; collecting relevant clinical information and detailed HPV vaccination histories for women 18-39 years of age; and estimating the annual rate of cervical cancer screening among the catchment area population. The first few years of the project provided key information, including data on HPV type distribution, before expected effect of vaccine introduction. The project's success exemplifies the flexibility of EIP's network to expand core activities to include emerging surveillance needs beyond acute infectious diseases. Project results contribute key information regarding the impact of HPV vaccination in the United States.

Is CMV a target in pediatric glioblastoma? Expression of CMV proteins, pp65 and IE1-72 and CMV nucleic acids in a cohort of pediatric glioblastoma patients.

While the 5-year overall survival is better in pediatric than in adult patients diagnosed with glioblastoma (GBM), outcomes in children remain very poor. Understanding the mechanisms of tumorigenesis and tumor propagation can identify therapeutic targets to improve these outcomes. Human cytomegalovirus (CMV) proteins and nucleic acids are present in the majority of adult GBM. Indeed, CMV is emerging as a potential glioma-associated target for anti-CMV agents and cellular therapeutics. Furthermore, CMV appears to contribute to GBM's malignant phenotype, although its role in tumorigenesis is less certain. In this cohort of 25 serially diagnosed pediatric GBMs, the largest described cohort to date, we used immunohistochemical staining and in situ hybridization to show the presence of CMV antigens pp65 and IE1-72 as well as CMV nucleic acids, respectively. Our cohort indicated either CMV antigen pp65 or IE1-72 was present in approximately 67 % of pediatric GBM samples. The majority of samples stained positive for either CMV antigen showing a cytoplasmic pattern in 25-50 % of cells within the sample at a moderate intensity, while a few samples showed nuclear staining and higher grade/intensity. Of 16 samples where in situ hybridization was performed, 13 (81 %) showed specific staining using a CMV genome specific probe cocktail. ISH positive samples showed high concordance with being pp65 or IE1-72 positive. These findings, paired with the association of CMV expression with poor prognosis and overall survival, indicate the need to further investigate how these antigens are promoting tumor growth and preventing cell death. Also, the expression of these antigens in a majority of tumor tissues should be considered for immunotherapeutic targets in cases of pediatric GBM.

Recurrent subependymoma of fourth ventricle with unusual atypical histological features: A case report.

Subependymoma is a rare subtype of benign ependymal neoplasm with distinct histological features. Anaplastic transformation has not yet been reported in this tumor to date. We present here a very unusual case of a 62-year-old woman with recurrent subependymoma of the fourth ventricle with multiple atypical histological features. Histologically, the resected recurrent tumor showed characteristic small cell clusters and nests of ependymal cells with an interspersed gliofibrillary matrix as seen in a classic subependymoma. In addition, there were very unusual histological features, including multiple areas of necrosis, microvascular proliferation, thrombosed blood vessels, and scattered mitotic figures. No coexisting ependymoma component of higher World Health Organization (WHO) grade was present. Immunohistochemically, MIB-1 labeling index was high, with up to 15% in the highest areas. Review of this patient's initial tumor, which was resected 6 years prior to recurrence, demonstrated features of a typical classic subependymoma without atypical features or a secondary tumor component. Subependymomas are known to be low-grade tumors and are usually cured if completely excised. The tumor presented here is unique in that several atypical pathological features were found in an otherwise typical subependymoma. Our case may represent anaplastic transformation of subependymoma, although no such examples have been reported to date.

Overexpression and constitutive nuclear localization of cohesin protease Separase protein correlates with high incidence of relapse and reduced overall survival in glioblastoma multiforme.

Separase, an enzyme that cleaves the chromosomal cohesin during mitosis, is overexpressed in a wide range of human epithelial cancers of breast, bone and prostate (Meyer et al., Clin Cancer Res 15(8):2703-2710, 2009). Overexpression of Separase in animal models results in aneuploidy and tumorigenesis. We have examined the expression and localization of Separase protein in adult and pediatric glioblastoma and normal brain specimens. Immunofluorescence microscopy and Western blot analysis showed significant overexpression of Separase in all adult and a subset of pediatric glioblastoma cells. Tumor status and patient survival strongly correlate with the mislocalization of Separase into the nucleus throughout all stages of the cell cycle. Unlike exclusively nuclear localization in mitotic control cells, glioblastoma samples have a significantly higher number of resting (interphase) cells with strong nuclear Separase staining. Additionally, patient survival analysis demonstrated a strong correlation between overexpression of Separase protein in adult glioblastoma and a high incidence of relapse and reduced overall survival. These results further strengthen our hypothesis that Separase is an oncogene whose overexpression induces tumorigenesis, and indicate that Separase overexpression and aberrant nuclear localization are common in many tumor types and may predict outcome in some human malignancies.

T cells redirected to EphA2 for the immunotherapy of glioblastoma.

Outcomes for patients with glioblastoma (GBM) remain poor despite aggressive multimodal therapy. Immunotherapy with genetically modified T cells expressing chimeric antigen receptors (CARs) targeting interleukin (IL)-13Rα2, epidermal growth factor receptor variant III (EGFRvIII), or human epidermal growth factor receptor 2 (HER2) has shown promise for the treatment of gliomas in preclinical models and in a clinical study (IL-13Rα2). However, targeting IL-13Rα2 and EGFRvIII is associated with the development of antigen loss variants, and there are safety concerns with targeting HER2. Erythropoietin-producing hepatocellular carcinoma A2 (EphA2) has emerged as an attractive target for the immunotherapy of GBM as it is overexpressed in glioma and promotes its malignant phenotype. To generate EphA2-specific T cells, we constructed an EphA2-specific CAR with a CD28-ζ endodomain. EphA2-specific T cells recognized EphA2-positive glioma cells as judged by interferon-γ (IFN-γ) and IL-2 production and tumor cell killing. In addition, EphA2-specific T cells had potent activity against human glioma-initiating cells preventing neurosphere formation and destroying intact neurospheres in coculture assays. Adoptive transfer of EphA2-specific T cells resulted in the regression of glioma xenografts in severe combined immunodeficiency (SCID) mice and a significant survival advantage in comparison to untreated mice and mice treated with nontransduced T cells. Thus, EphA2-specific T-cell immunotherapy may be a promising approach for the treatment of EphA2-positive GBM.

Neurohistopathological findings at the electrode-tissue interface in long-term deep brain stimulation: systematic literature review, case report, and assessment of stimulation threshold safety.

OBJECTIVES: Despite the widespread use of deep brain stimulation (DBS) in the treatment of neurologic disorders for over a quarter of a century, there has not been a systematic review and analyses of cases in which long-term postmortem clinic-pathologic data have been collected demonstrating the effects of chronically implanted electrodes and electrical stimulation on human brain tissue. Our objective is to provide a comprehensive systematic review of the literature on clinicopathologic findings of DBS tissue-electrode interface (TEI) and to determine types and prevalences of neuropathological findings among electrode materials and stimulation parameters and to augment this with previously unpublished histopathological data, images, and analyses from a DBS case implanted for 12 years, providing the longest duration histopathological follow-up. MATERIALS AND METHODS: A Medline literature review identified DBS cases upon which postmortem clinicopathologic follow-up was performed with adequate characterization of TEI. Direct follow-up with authors augmented this with unpublished data and neuropathological details. RESULTS: We identified 40 cases, mean age 59.1 ± 13.0 (range: 21-88) years, involving 58 implanted DBS electrodes. The mean postmortem histopathological follow-up of the implanted DBS electrodes was 22.2 ± 29.2 (range: 0.067-146) months, including our case with a 12-year follow-up. The following histological changes were identified: fibrous sheaths (5-25 µm thickness) surrounding the electrode (94%), fibrillary gliosis (73%), reactive astrocytes (78%), multinucleated giant cells (75%), mononuclear leukocytes (92%), and macrophages (91%). Microglial activation (60%), axonal spheroids (64%), and neuronal loss (60%) were less common and absent at 12-year follow-up in the index case. This is seventh case reporting T cell presence at the TEI. CONCLUSIONS: Neuropathological findings from published cases and our 12-year follow-up index case confirm the long-term safety of neuromodulation and stimulation thresholds and demonstrate persistence of T cells and occasional subclinical focal tissue injury.

Caring for Caregivers: National Case Management Week: October 13-10, 2024.

The population of individuals over the age of 60 is expected to double by 2050, resulting in nearly 2.1 billion people. Statistics show that unpaid family caregiving is on the rise and will likely go higher. A look at caregiver statistics is revealing. There are ways that institutions and case managers can support this growing population.

Advanced Hospital Healthcare at Home-How Is It Going?

The Centers for Medicare & Medicaid Services' (CMS) Acute Hospital Care at Home (AHCAH) waiver, which launched in November 2020, has prompted hundreds of hospitals across the country to initiate programs that allow certain patients to complete their acute care stays in the familiar comfort of their homes. But this waiver is about to expire in December 2024. It is a success; but can we continue it?
