ABSTRACT

AIM OF THE WORK: This study aimed at assessing the dominance of risk practices associated with HCV endemicity in Egypt and detecting the behavioral development level concerning different aspects of HCV risk behaviors with respect to age and gender. The survey highlights the most cost-effective strategies that could accelerate HCV elimination in Egypt.

SUBJECTS AND METHODS: A national household survey targeted 3780 individuals (age range: 10-85 years). The sample was a systematic probability proportionate to size from 6 governorates representing the six major subdivisions of Egypt. The indicators used for assessing the behavioral development level towards HCV included six domains: awareness (7 indicators), perceived risk (5 indicators), motivation with the intention to change (4 and 5 indicators for males and females respectively), trial, rejection or adoption (6 and 5 indicators for males and females respectively).

RESULTS: The study revealed that along the continuum of behavior development, the percentage of the participants who acquired half of the scores was as follows: 73.1% aware, 69.8% developed perceived risk, 80.6% motivated with only 28.9% adopting the recommended behaviors, 32% rejected them, 2.3% were in the trial stage versus 35.8% who did not try any. Adolescents had significantly lower levels of development for almost all domains when compared to adults. Statistical higher significance was detected in favor of adults, employees, married, Lower Egypt governorates, and university-educated participants (p<0.001) regarding awareness, perceived risk, and motivation scores. More than half of the participants incorrectly believed that contaminated food, sharing food utilities, contaminated water, mosquitoes, and schistosomiasis would lead to HCV transmission.

CONCLUSION: Egypt would be closer to HCV elimination when cost-effective strategies are directed not towards creating awareness, perceived risk or motivation to change- (at an acceptable level)- but towards motivating adopting risk-reduction behaviors for HCV, tackling misconceptions and reinforcement of social support.

ABSTRACT

CT-based quantitative analysis of any ossification center in the cranium has not previously been carried out due to the limited availability of human fetal material. Detailed morphometric data on the development of ossification centers in the human fetus may be useful in the early detection of congenital defects. Ossification disorders in the cranium are associated with either a delayed development of ossification centers or their mineralization. These aberrations may result in the formation of accessory skull bones that differ in shape and size, and the incidence of which may be misdiagnosed as, e.g., skull fractures. The study material comprised 37 human fetuses of both sexes (16♂, 21♀) aged 18-30 weeks. Using CT, digital image analysis software, 3D reconstruction and statistical methods, the linear, planar and spatial dimensions of the occipital squama ossification center were measured. The morphometric characteristics of the fused ossification center of the occipital squama show no right-left differences. In relation to gestational age, the ossification center of the occipital squama grows linearly in its right and left vertical diameters, logarithmically in its transverse diameters of both the interparietal and supraoccipital parts and projection surface area, and according to a quadratic function in its volume. The obtained numerical findings of the occipital squama ossification center may be considered age-specific references of relevance in both the estimation of gestational age and the diagnostic process of congenital defects.

ABSTRACT

BACKGROUND: Epilepsy is thought to be caused by witchcraft, evil spirit, and God’s punishment for sins in many developing countries. As a result, people with epilepsy and their families usually suffer from stigma, discrimination, depression, and other psychiatric problems. Thus, this study aimed to assess the quality of life and its associated factors among epileptic patients attending public hospitals in North Wollo Zone, Northeast Ethiopia.

METHODS: An institution-based cross-sectional study design was employed in this study. A simple random sampling technique was utilized. Health-related quality of life was measured based on the total score of the Quality of Life in Epilepsy Inventory (QOLIE-31) instrument. Data were entered into Epi-data 3.1 statistical package and exported to SPSS Version 20 for further analysis. Linear regression models were used to assess the relationship between quality of life and the independent variables. Statistically significant values were declared at a P-value of < 0.05.

RESULTS: A total of 395 patients participated in the study making the response rate 98.5%. The mean age of the participants was 32.39 ±10.71 years. More than half, 199 (50.4%) of epileptic patients had an overall weighted average health related quality of life score of mean and above. Male sex (B = 4.34, 95%CI, 0.41, 8.27, P = 0.03), higher educational status (B = 7.18, 95%CI, 1.39, 13.00, P = 0.015) and age at onset of epilepsy (B = 0.237, 95%CI, 0.02, 0.45, P = 0.035) were associated with increased health related quality of life score. On the other hand, family history of epilepsy (B = -4.78, 95%CI,-9.24,-0.33, P = 0.035), uncontrolled seizure (B = -11.08, 95%CI,-15.11,-7.05, P < 0.001), more than 5 pre-treatment number of seizures (B = -4.86, 95%CI,-8.91,-0.81, P = 0.019), poor drug adherence (B = -11.65, 95%CI,-16.06,-7.23, P < 0.001), having moderate (B = -4.526, 95%CI,-8.59,-0.46, P = 0.029) to sever (B = -12.84, 95%CI,-18.30,-7.37, P < 0.001) anxiety and depression, believing that epilepsy is caused by evil spirit (B = -7.04, 95%CI,-11.46,-2.61, P = 0.002), drinking alcohol (B = -5.42, 95%CI,-10.72,-0.13, P = 0.045), and having other co-morbidities (B = -9.35, 95%CI,-14.35,-4.36, P < 0.001) were significantly negatively associated with the health related quality of life score among epileptic patients.

CONCLUSIONS: Only around half of the epileptic patients have a good health-related quality of life. In addition, multiple variables including family history, uncontrolled seizure, and poor drug adherence were associated with quality of life among epileptic patients. Hence, targeting these variables in epilepsy management is recommended.

ABSTRACT

PURPOSE: To describe the extent of participation and engagement in family activities and explore variables potentially impacting on these factors in family activities among girls and young women with Rett syndrome (RTT) under the age of 21.

MATERIALS AND METHODS: The Child Participation in Family Activities (Child-PFA) questionnaire was sent to parents in the target group (n = 42). Additionally, age, number of siblings at home, ambulation level, clinical severity and level of hand function were recorded to explore possible impact. Data were analyzed using descriptive statistics, Fishers exact test and cross-tables.

RESULTS: 23 families participated. Highest degrees of participation and engagement were seen in social and stationary family activities. Indoor activities were frequent and showed high levels of participation and engagement, Outdoor activities were infrequent and showed low levels of participation despite a high degree of engagement. Routine activities were frequent but showed moderate to low participation and engagement. A negative association was found between participation in watching a movie and number of siblings living at home, and positive associations between engagement and age in three family activities.

CONCLUSION: Therapists working with this target group may benefit from focusing on engagement in routine activities and modification of family activities.IMPLICATIONS FOR REHABILITATIONTherapists may benefit from focusing on engagement in routine activities in the goal setting process and intervention as they occur on a daily basis, giving the opportunity for development of new skills.Therapists may benefit from focusing on assistive devices or other compensatory strategies for outdoor activities and activities that require a certain amount of hand function.Therapists may benefit from modifying the family’s activities so that they require more social and mental participation and focus on experiencing different types of sensory input e.g., sound, tactile, visual or vestibular input rather than taking part in the activity by using their hands.

ABSTRACT

BACKGROUND: Forecasting methods rely on trends and averages of prior observations to forecast coronavirus disease 2019 (COVID-19) case counts. COVID-19 forecasts have received much media attention and numerous platforms have been created to inform the public. However, forecasting effectiveness varies by geographic scope and are affected by changing assumptions in behaviors and preventative measures in response to the pandemic. Due to time requirements for developing a COVID-19 vaccine, evidence is needed to inform short-term forecasting method selection at county, health district, and state levels.

OBJECTIVE: COVID-19 forecasts keep the public informed and contribute to public policy. As such, proper understanding of forecasting purposes and outcomes is needed to advance knowledge of health statistics for policy makers and the public. Using publicly available real-time data provided online, we evaluate the performance of seven forecasting methods utilized to forecast cumulative COVID-19 case counts. Forecasts are evaluated based on how well they forecast one-. three-, and seven-days forward when utilizing one-, three-, seven-, or all-prior days’ cumulative case counts during early onset. This study provides an objective evaluation of the forecasting methods to identify forecasting model assumptions that contribute to lower error in forecasting COVID-19 cumulative case growth. This information benefits professionals, decision makers, and the public relying on the data provided by short-term case count estimates at varied geographic levels.

METHODS: One-, three-, and seven-days forecasts are created at the county, health district, and state levels using: (1) a naïve approach; (2) Holt-Winters exponential smoothing (HW); (3) growth rate (Growth); (4) moving average (MA); (5) autoregressive (AR); (6) autoregressive moving average (ARMA); and (7) autoregressive integrated moving average (ARIMA). Forecasts rely on Virginia’s 3,463 historical county-level cumulative case counts from March 7 – April 22, 2020, as reported by The New York Times. Statistically significant results are identified using 95% confidence intervals of Median Absolute Error (MdAE) and Median Absolute Percentage Error (MdAPE) error metrics of the resulting 216,698 forecasts.

RESULTS: Next-day MA forecast with three-day lookback obtained the lowest MdAE (0.67, 0.49-0.84, P < .001) and statistically significantly differs from 39 (66.1%) to 53 (89.8%) of alternatives at each geographic level at a significance level of 0.01. For short-range forecasting, methods assuming stationary means of prior days’ counts outperform methods with assumptions of weak- or non-stationarity means. MdAPE results reveal statistically significant differences across geographic levels.

CONCLUSIONS: For short-range COVID-19 cumulative case count forecasting at the county, health district, and state levels during early onset: (1) MA is effective for forecasting one-, three-, and seven-days’ cumulative case counts; (2) exponential growth is not the best representation of case growth during early onset when the public is aware of the virus; and (3) geographic resolution is a factor in forecasting method selection.

ABSTRACT

BACKGROUND: Few ICU staffing studies examine collaboration structures among healthcare workers. Knowledge about how healthcare workers (HWs) are connected to care for critically ill COVID-19 (C19) patients provides evidence for characterizing the relationship between team structures, care quality, and patient safety.

OBJECTIVE: To discover the distinctions of teamwork structures in C19 critical care by comparing HW collaboration associated with the management of critically ill patients with and without C19.

METHODS: In this retrospective study, we apply network analysis to the utilization of electronic health records (EHRs) of 76 critically ill patients (38 with and 38 without C19) admitted to a large academic medical center to learn HW collaboration. We use the EHRs for adult patients admitted to the C19 ICU at Vanderbilt University Medical Center (Nashville, Tennessee, USA) between March 17, 2020 and May 31, 2020. We matched each C19 patient on age, gender, and length of stay, with NC19 patients admitted to the Medical ICU (MICU) between December 1, 2019 and February 29, 2020. Then we use two sociometric measurements, including eigencentrality and betweenness, to quantify HWs’ status in the networks. Eigencentrality characterizes the degree to which an HW is likely to be a core person in the collaboration. Betweenness centrality refers to whether an HW lies on the path of others who are not directly connected, which is leveraged to characterize the broad skillsets of an HW. We further measure patient staffing intensity in terms of the number of HWs interacting with the EHR of a patient. We assess the extent to which the core and betweenness status of HWs, as well as patient staffing intensity, in C19 and Non-C19 (NC19) critical care are statistically different using Mann-Whitney U tests at the 95% confidence level.

RESULTS: HWs are likely to more frequently work with each other in C19 than NC19 critical care (median eigencentrality values of 0.096 vs. 0.057, respectively; p = 1.5×10e-9). Internal medicine physicians exhibit a higher core status in the C19 critical care than NC19 (p = 1.2 ×10e-3). Nurse practitioners exhibit a more betweenness status in the C19 than NC19 care (p = 3.10 ×10e-4). In comparison to the NC19 setting, the EHRs of C19 critically ill patients were utilized by a larger number of internal medicine nurse practitioners (p = 1.27 ×10e-5), cardiovascular nurses (p = 8.48 ×10e-6) and surgical ICU nurses (p = 1.62 ×10e-3), as well as a smaller number of resident physicians (p = 5.96 ×10e-4).

CONCLUSIONS: Network analysis methodologies and EHR utilization data provide a novel way to learn distinctions of collaboration structures in C19 critical care, which can be leveraged by healthcare organizations to understand the novel additions the C19 brings to the collaboration structure in urgent care.

ABSTRACT

BACKGROUND: COVID-19 pandemic caused by SARS-CoV-2 continued to impact health systems throughout the world with serious medical challenges being imposed on many African countries such as Nigeria. Although emerging studies have identified lymphopenia as a driver of cytokine storm, disease progression and poor outcomes in infected patients, its immunopathogenesis, environmental and genetic determinants remain unclear. Understanding the interplay of these determinants in the context of lymphopenia and COVID-19 complications in African patients may help in risk stratification and appropriate deployment of targeted treatment regimens with repurposed drugs to improve prognosis.

OBJECTIVE: This study is designed to investigate the role of vitamin D status, vasculopathy, apoptotic pathway and vitamin D receptor gene polymorphisms in the immunopathogenesis of lymphopenia among SARS-CoV-2 infected Africans.

METHODS: This cross-sectional study will enrol 200 study participants categorized as SARS-CoV-2 negative (n=69), COVID-19 mild (n=32), hospitalized (n=72) and recovered (n=37) from two purposively selected health facilities in Lagos State. Sociodemographic, travel history and co-morbidity information will be obtained from case file and study pre-tested interviewer-based structured questionnaire. Venous blood samples (5ml) collected between 8.00-10.00 h and aliquoted into EDTA and plain tubes will be used for complete blood count and CD4 T cells assays to determine lymphopenia (Lymphocyte count < 1000 cells/uL) and CD4 T lymphocyte levels as well as measuring the concentrations of vitamin D, caspase 3, sVCAM-1 and sFasL using an autoanalyzer, flow cytometry and ELISA techniques. Genomic DNA will be extracted from buffy coat and used as template for the amplification of apoptosis related genes (Bax, Bcl-2, BCl-2LI2) by PCR and genotyping of vitamin D receptor (VDR: Apa1, Foh1 and Bsm1) gene polymorphisms by PCR-RFLP and capillary sequencing. Total RNA will also be extracted, reverse transcribed and subsequently quantitated by RT-PCR to monitor the expression of apoptosis genes in the four categories of COVID-19 study participants enrolled. Data analyses, which include test of association between VDR gene polymorphisms and study outcomes (Lymphopenia and hypovitaminosis D prevalence, mild/moderate and severe infections) will be performed using the R Statistical Software. Hardy-Weinberg Equilibrium (HWE) and linkage disequilibrium analyses for alleles, genotype and haplotypes of the genotyped VDR gene will also be carried out.

RESULTS: A total of 45 participants comprising 37 SARS-CoV-2 negative and 8 COVID-19 recovered participants have been enrolled so far with their complete blood counts and CD4 T lymphocyte counts determined as well as having all their serum samples and genomic DNA and RNA sample extracted and stored at -200C until further analyses. Other expected outcomes include prevalence and distribution of lymphopenia and hypovitaminosis D among the control (SARS-CoV-2 negative), confirmed, hospitalized and recovered SARS-CoV-2 positive study participants, association lymphopenia with CD4 T lymphocyte level, serum vitamin D, sVCAM-1, sFasL and caspase 3 levels in hospitalized COVID-19 patients, expression levels of apoptosis related genes among hospitalized COVID-19 study participants, those with lymphopenia compared with those without lymphopenia and Frequency distribution of alleles, genotypes and haplotypes of VDR gene polymorphisms in COVID-19 afflicted Nigerians studied.

CONCLUSIONS: This study will aid in the genotypic and phenotypic stratification of COVID-19 afflicted Nigerian patients with and without lymphopenia to enable biomarker discovery and pave way for appropriate and timely deployment of patient-centered treatments to improve prognosis.

ABSTRACT

Purpose Developmental language disorder (DLD) is a developmental disorder where children fail to acquire language in the absence of a clear cause. Many studies have reported general motor deficits in children with DLD, but no studies have uncovered a cure. The purpose of our study is to better understand the underlying motor deficits in DLD, starting from uninhibited primary reflexes-which are the most basic stage of motor development. Knowledge of this motor-language relationship should lead to earlier and more targeted interventions in young children with DLD. Method Children with DLD (n = 75, age range: 4-10 years) and 99 age-matched typically developing (TD) children completed a nonword repetition test to assess DLD and six other tests to assess primitive reflexes. Results Children with DLD demonstrated higher levels of persistent primitive reflexes compared to TD children. As the scores for neuromotor immaturity increased, nonword repetition test scores decreased (r = -.44, p < .01). Results indicated that TD children exhibited lower neuromotor immaturity (M = 7.63, SD = 3.75) compared to children with DLD (M = 13.51, SD = 4.47). All primitive reflexes (the Moro reflex, the symmetrical tonic neck reflex in flexion and in extension, the asymmetrical tonic neck reflex, the tonic labyrinthine reflex, and the Galant reflex) turned out to be statistically significantly different for the TD and DLD groups (p < .001). We also observed some differences between sexes. Conclusions Children with impaired language development underwent slower neuromotor development. However, further research is needed to determine whether motor intervention programs that inhibit primitive reflexes are helpful for children with DLD.

ABSTRACT

PURPOSE: Patients with the activated B-cell-like (ABC) subtype of diffuse large B-cell lymphoma (DLBCL) historically showed inferior survival with standard rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Phase II studies demonstrated that adding the immunomodulatory agent lenalidomide to R-CHOP improved outcomes in ABC-type DLBCL. The goal of the global, phase III ROBUST study was to compare lenalidomide plus R-CHOP (R2-CHOP) with placebo/R-CHOP in previously untreated, ABC-type DLBCL.

METHODS: Histology and cell-of-origin type were prospectively analyzed by central pathology prior to random assignment and study treatment. Patients with ABC-DLBCL received lenalidomide oral 15 mg/d, days 1-14/21 plus standard R-CHOP21 versus placebo/R-CHOP21 for six cycles. The primary end point was progression-free survival (PFS) per independent central radiology review.

RESULTS: A total of 570 patients with ABC-DLBCL (n = 285 per arm) were stratified by International Prognostic Index score, age, and bulky disease, and randomly assigned to R2-CHOP or placebo/R-CHOP. Baseline demographics were similar between arms. Most patients completed six cycles of treatment: 74% R2-CHOP and 84% placebo/R-CHOP. The most common grade 3/4 adverse events for R2-CHOP versus placebo/R-CHOP were neutropenia (60% v 48%), anemia (22% v 14%), thrombocytopenia (17% v 11%), and leukopenia (14% v 15%). The primary end point of PFS was not met, with a hazard ratio of 0.85 (95% CI, 0.63 to 1.14) and P = .29; median PFS has not been reached for either arm. PFS trends favoring R2-CHOP over placebo/R-CHOP were seen in patients with higher-risk disease.

CONCLUSION: ROBUST is the first DLBCL phase III study to integrate biomarker-driven identification of eligible ABC patients. Although the ROBUST trial did not meet the primary end point of PFS in all patients, the safety profile of R2-CHOP was consistent with individual treatments with no new safety signals.

ABSTRACT

Purpose This article describes the development and initial validation of the Speech-Language Pathologist (SLP) Involvement in Multi-Tiered System of Supports (MTSS) Questionnaire. It was developed to measure the extent to which SLPs are involved in MTSS at their school site(s). Method A total of 567 SLPs practicing in the United States responded to up to 39 Likert-type items meant to reflect six domains: scope of practice, professional development, leadership, consulting/collaborating, assessment and analysis, and intervention. Measurement quality was evaluated in terms of score reliability and validity. An exploratory factor analysis was conducted to evaluate the internal structure of the questionnaire responses. A three-factor model with the following dimensions of Carrying out Roles and Responsibilities, Leading, and Planning and Providing Interventions was supported. Loadings for retained factors ranged from .35 to .87. Internal consistency estimates ranged from .87 to .92. Descriptive statistics summarized the overall involvement of SLPs in MTSS, and responses to questions to assess the feasibility and acceptability of this questionnaire were analyzed. Results Questionnaire responses indicated that SLPs infrequently engage in MTSS activities. The item with the highest mean was related to SLPs collaborating with teachers to help them address students’ speech and language disorders in their classrooms. Most of the SLPs who took the questionnaire found it easy to complete, but only some found the information to be useful. Conclusions The infrequent involvement of SLPs in MTSS indicates a need to disseminate information on the potentially valuable roles SLPs can play in MTSS implementation. This tool may be used by SLPs to better understand contributions they can make within an MTSS framework and self-reflect on their current levels of involvement.
