Divergent Caregiver and Youth Perspectives Regarding Behavioral Health Needs and Psychosocial Functioning: An Exploratory Study

Background. To promote effectiveness in behavioral health treatment, the system of care framework and wraparound model accentuate inclusion of family and youth as important stakeholders, not just as consumers. This has challenged conventional practices; and youth and caregivers' perspectives have become integral to treatment planning and service delivery. This study explored caregivers and youth's perspectives of behavioral health needs and psychosocial functioning. Methods. This exploratory study utilized data collected in a Midwestern, suburban county as part of the national Child and Family Study of youth with complex behavioral health needs enrolled in the Child Mental Health Wraparound initiative. The sample consisted of 25 caregiver-youth pairs. Assessment measures included the Pediatric Symptom Checklist (PSC) and the Columbia Impairment Scale (CIS). Independent t-tests were used to examine differences in caregiver and youth perspectives. Results. Significant differences were identified in caregivers and youth's perspectives of youth's behavioral health on the PSC, but no significant differences between caregivers and youth on the CIS measure. Responses showed that compared to youth, caregivers perceived a higher level of functional impairment in interpersonal relationships, academic, and community functioning. Further, caregivers' views of severity of functional impairment varied based on the caregiver type. Conclusion. Divergent perspectives regarding youth's behavioral health needs and functioning between caregivers and youth have implications for behavioral health treatment planning and service delivery. Additional research is needed on collaborative assessments and implications of different views for practice and outcomes

Transcriptome-based analysis of blood samples reveals elevation of DNA damage response, neutrophil degranulation, cancer and neurodegenerative pathways in Plasmodium falciparum patients

Background: Malaria caused by Plasmodium falciparum results in severe complications including cerebral malaria (CM) especially in children. While the majority of falciparum malaria survivors make a full recovery, there are reports of some patients ending up with neurological sequelae or cognitive deficit.// Methods: An analysis of pooled transcriptome data of whole blood samples derived from two studies involving various P. falciparum infections, comprising mild malaria (MM), non-cerebral severe malaria (NCM) and CM was performed. Pathways and gene ontologies (GOs) elevated in the distinct P. falciparum infections were determined.// Results: In all, 2876 genes were expressed in common between the 3 forms of falciparum malaria, with CM having the least number of expressed genes. In contrast to other research findings, the analysis from this study showed MM share similar biological processes with cancer and neurodegenerative diseases, NCM is associated with drug resistance and glutathione metabolism and CM is correlated with endocannabinoid signalling and non-alcoholic fatty liver disease (NAFLD). GO revealed the terms biogenesis, DNA damage response and IL-10 production in MM, down-regulation of cytoskeletal organization and amyloid-beta clearance in NCM and aberrant signalling, neutrophil degranulation and gene repression in CM. Differential gene expression analysis between CM and NCM showed the up-regulation of neutrophil activation and response to herbicides, while regulation of axon diameter was down-regulated in CM.// Conclusions: Results from this study reveal that P. falciparum-mediated inflammatory and cellular stress mechanisms may impair brain function in MM, NCM and CM. However, the neurological deficits predominantly reported in CM cases could be attributed to the down-regulation of various genes involved in cellular function through transcriptional repression, axonal dysfunction, dysregulation of signalling pathways and neurodegeneration. It is anticipated that the data from this study, might form the basis for future hypothesis-driven malaria research

Effects of Fish Cage Culture on Water and Sediment Quality in the Gorge Area of Lake Volta in Ghana: A Case Study of Lee Fish Cage Farm

The study determined the impacts of fish cage farming on the gorge area of Lake Volta. Water and sediment samples were collected from six sites in the Lee Cage Farm; four from sections with cages and two from about 1300 m upstream of the farm which served as the control. Water quality variables monitored were pH, temperature, dissolved oxygen, nitrate-nitrogen, ammonia-nitrogen, orthophosphate, faecal coliforms and total coliforms. Variables monitored in the sediment were organic matter, total carbon, total nitrogen and total phosphorus. There were variations in water quality between the farmed and control sites but the differences were not significant (p > 0.05). The mean counts of total coliform in the water ranged from 940 - 3318 cfu/100 ml while faecal coliforms ranged from 113 - 552 cfu/100 ml at the farmed site. The mean total coliform count at the control site ranged from 837 - 6960 cfu/100 ml while the faecal coliforms ranged from 48 - 120 cfu/100 ml. Therefore, there was significant variation between the faecal coliforms count at the two sites (p = 0.046). The results suggest that the general microbiological quality of the water at the study area was unacceptable

Prodromal frontotemporal dementia: clinical features and predictors of progression

Background: The prodromal phase of frontotemporal dementia (FTD) is still not well characterized, and conversion rates to dementia and predictors of progression at 1-year follow-up are currently unknown. // Methods: In this retrospective study, disease severity was assessed using the global CDR plus NACC FTLD. Prodromal FTD was defined to reflect mild cognitive or behavioural impairment with relatively preserved functional independence (global CDR plus NACC = 0.5) as well as mild, moderate and severe dementia (classified as global CDR plus NACC = 1, 2, 3, respectively). Disease progression at 1-year follow-up and serum NfL measurements were acquired in a subgroup of patients. // Results: Of 563 participants, 138 were classified as prodromal FTD, 130 as mild, 175 as moderate and 120 as severe FTD. In the prodromal and mild phases, we observed an early increase in serum NfL levels followed by behavioural disturbances and deficits in executive functions. Negative symptoms, such as apathy, inflexibility and loss of insight, predominated in the prodromal phase. Serum NfL levels were significantly increased in the prodromal phase compared with healthy controls (average difference 14.5, 95% CI 2.9 to 26.1 pg/mL), but lower than in patients with mild FTD (average difference -15.5, 95% CI -28.4 to -2.7 pg/mL). At 1-year follow-up, 51.2% of patients in the prodromal phase had converted to dementia. Serum NfL measurements at baseline were the strongest predictors of disease progression at 1-year follow-up (OR 1.07, 95% CI 1.03 to 1.11, p < 0.001). // Conclusions: Prodromal FTD is a mutable stage with high rate of progression to fully symptomatic disease at 1-year follow-up. High serum NfL levels may support prodromal FTD diagnosis and represent a helpful marker to assess disease progression

Effect of Social Support and Marital Status on Perceived Surgical Effectiveness and 30-Day Hospital Readmission

Study Design: Retrospective cohort review. Objective: To determine whether higher levels of social support are associated with improved surgical outcomes after elective spine surgery. Methods: The medical records of 430 patients (married, n = 313; divorced/separated/widowed, n = 71; single, n = 46) undergoing elective spine surgery at a major academic medical center were reviewed. Patients were categorized by their marital status at the time of surgery. Patient demographics, comorbidities, and postoperative complication rates were collected. All patients had prospectively collected outcomes measures and a minimum of 1-year follow-up. Patient reported outcomes instruments (Oswestry Disability Index, Short Form-36, and visual analog scale-back pain/leg pain) were completed before surgery, then at 1 year after surgery. Results: Baseline characteristics were similar in all cohorts. There was no statistically significant difference in the length of hospital stay across all 3 cohorts, although single patients had longer duration of in-hospital stays that trended toward significance (single 6.24 days vs married 4.53 days vs divorced/separated/widowed 4.55 days, P = .05). Thirty-day readmission rates were similar across all cohorts (married 7.03% vs divorced/separated/widowed 7.04% vs single 6.52%, P = .99). Additionally, there were no significant differences in baseline and 1-year patient reported outcomes measures between all groups. Conclusions: Increased social support did not appear to be associated with superior short and long-term clinical outcomes after spine surgery; however, it was associated with a shorter duration of in-hospital stay with no increase in 30-day readmission rates

Distinct conformations, aggregation and cellular internalization of different tau strains

The inter-cellular propagation of tau aggregates in several neurodegenerative diseases involves, in part, recurring cycles of extracellular tau uptake, initiation of endogenous tau aggregation, and extracellular release of at least part of this protein complex. However, human brain tau extracts from diverse tauopathies exhibit variant or “strain” specificity in inducing inter-cellular propagation in both cell and animal models. It is unclear if these distinctive properties are affected by disease-specific differences in aggregated tau conformation and structure. We have used a combined structural and cell biological approach to study if two frontotemporal dementia (FTD)-associated pathologic mutations, V337M and N279K, affect the aggregation, conformation and cellular internalization of the tau four-repeat domain (K18) fragment. In both heparin-induced and native-state aggregation experiments, each FTD variant formed soluble and fibrillar aggregates with remarkable morphological and immunological distinctions from the wild type (WT) aggregates. Exogenously-applied oligomers of the FTD tau-K18 variants (V337M and N279K) were significantly more efficiently taken up by SH-SY5Y neuroblastoma cells than WT tau-K18, suggesting mutation-induced changes in cellular internalization. However, shared internalization mechanisms were observed: endocytosed oligomers were distributed in the cytoplasm and nucleus of SH-SY5Y cells and the neurites and soma of human induced pluripotent stem cell-derived neurons where they co-localized with endogenous tau and the nuclear protein nucleolin. Altogether, evidence of conformational and aggregation differences between WT and disease-mutated tau K18 is demonstrated, which may explain their distinct cellular internalization potencies. These findings may account for critical aspects of the molecular pathogenesis of tauopathies involving WT and mutated tau

Immediate Postoperative Pain Scores Predict Neck Pain Profile up to 1 Year Following Anterior Cervical Discectomy and Fusion

Study Design: Retrospective cohort review. Objective: To assess whether immediate postoperative neck pain scores accurately predict 12-month visual analog scale-neck pain (VAS-NP) outcomes following Anterior Cervical Discectomy and Fusion surgery (ACDF). Methods: This was a retrospective study of 82 patients undergoing elective ACDF surgery at a major academic medical center. Patient reported outcomes measures VAS-NP scores were recorded on the first postoperative day, then at 6-weeks, 3, 6, and 12-months after surgery. Multivariate correlation and logistic regression methods were utilized to determine whether immediate postoperative VAS-NP score accurately predicted 1-year patient reported VAS-NP Scores. Results: Overall, 46.3% male, 25.6% were smokers, and the mean age and body mass index (BMI) were 53.7 years and 28.28 kg/m2, respectively. There were significant correlations between immediate postoperative pain scores and neck pain scores at 6 weeks VAS-NP (P = .0015), 6 months VAS-NP (P = .0333), and 12 months VAS-NP (P = .0247) after surgery. Furthermore, immediate postoperative pain score is an independent predictor of 6 weeks, 6 months, and 1 year VAS-NP scores. Conclusion: Our study suggests that immediate postoperative patient reported neck pain scores accurately predicts and correlates with 12-month VAS-NP scores after an ACDF procedure. Patients with high neck pain scores after surgery are more likely to report persistent neck pain 12 months after index surgery

A genome-wide association study of plasma phosphorylated tau181

Plasma phosphorylated tau at threonine-181 (P-tau181) demonstrates promise as an accessible blood-based biomarker specific to Alzheimer's Disease (AD), with levels recently demonstrating high predictive accuracy for AD-relevant pathology. The genetic underpinnings of P-tau181 levels, however, remain elusive. This study presents the first genome-wide association study of plasma P-tau181 in a total sample of 1153 participants from 2 independent cohorts. No loci, other than those within the APOE genomic region (lead variant = rs429358, beta = 0.32, p =8.44 × 10−25) demonstrated association with P-tau181 at genome-wide significance (p < 5 × 10−08), though rs60872856 on chromosome 2 came close (beta = -0.28, p = 3.23 × 10−07, nearest gene=CYTIP). As the APOE ε4 allele is already a well-established genetic variant associated with AD, this study found no evidence of novel genetic associations relevant to plasma P-tau181, though presents rs60872856 on chromosome 2 as a candidate locus to be further evaluated in future larger size GWAS
