Never Deaf of Learning with Heart: Understanding the Essence of Handling Pupils with Hearing Impairment
This transcendental phenomenology study aimed at describing and understanding the lived experience of eight (8) Special education teachers handling learners with hearing impairment.Specifically, they were private school teachers in the cities of Biñan, Sta. Rosa and San Pedro Laguna, Philippines who were purposively selected using inclusion criteria. Framed with the approach of Moustakas (1994) as cited by Creswell (2007), the researchers carefully analyzed the participantsâ verbatim accounts which resulted in six (6) themes categorized into textural and structural descriptions. Collectively taken, the essence of the study highlighted the participantsâ experience in handling hearing-impaired learners which covered engaging them in different activities (Theme 1), customized communication with them (Theme 2), and love and drive to reach out to these individuals (Theme 3). They coped with the challenges they face by clinging to the vital role of assessment tools (Theme 4), highlighting values in teaching (Theme 5) and viewing their profession as a calling of commitment and devotion (Theme 6). The lived experiences of special education teachers with learners diagnosed with hearing impairment may serve as a feedback for special education instructional materials suppliers or developers in improving the contents of their works to better cater the needs of special education teachers in terms of the choice of innovated instructional materials that specifically address the learning needs of students in special education
Therapeutic considerations for prevention and treatment of thrombotic events in COVID-19
Thrombosis is a known complication of SARS-CoV-2 infection, particularly within a severely symptomatic subset of patients with COVID-19 disease, in whom an aggressive host immune response leads to cytokine storm syndrome (CSS). The incidence of thrombotic events coinciding with CSS may contribute to the severe morbidity and mortality observed in association with COVID-19. This review provides an overview of pharmacologic approaches based upon an emerging understanding of the mechanisms responsible for thrombosis across a spectrum of COVID-19 disease involving an interplay between immunologic and pro-thrombotic events, including endothelial injury, platelet activation, altered coagulation pathways, and impaired fibrinolysis
Global Search for New Physics with 2.0/fb at CDF
Data collected in Run II of the Fermilab Tevatron are searched for
indications of new electroweak-scale physics. Rather than focusing on
particular new physics scenarios, CDF data are analyzed for discrepancies with
the standard model prediction. A model-independent approach (Vista) considers
gross features of the data, and is sensitive to new large cross-section
physics. Further sensitivity to new physics is provided by two additional
algorithms: a Bump Hunter searches invariant mass distributions for "bumps"
that could indicate resonant production of new particles; and the Sleuth
procedure scans for data excesses at large summed transverse momentum. This
combined global search for new physics in 2.0/fb of ppbar collisions at
sqrt(s)=1.96 TeV reveals no indication of physics beyond the standard model.Comment: 8 pages, 7 figures. Final version which appeared in Physical Review D

Genetic variation associated with circulating monocyte count in the eMERGE Network
With white blood cell count emerging as an important risk factor for chronic inflammatory diseases, genetic associations of differential leukocyte types, specifically monocyte count, are providing novel candidate genes and pathways to further investigate. Circulating monocytes play a critical role in vascular diseases such as in the formation of atherosclerotic plaque. We performed a joint and ancestry-stratified genome-wide association analyses to identify variants specifically associated with monocyte count in 11 014 subjects in the electronic Medical Records and Genomics Network. In the joint and European ancestry samples, we identified novel associations in the chromosome 16 interferon regulatory factor 8 (IRF8) gene (P-value = 2.78Ă10(â16), ÎČ = â0.22). Other monocyte associations include novel missense variants in the chemokine-binding protein 2 (CCBP2) gene (P-value = 1.88Ă10(â7), ÎČ = 0.30) and a region of replication found in ribophorin I (RPN1) (P-value = 2.63Ă10(â16), ÎČ = â0.23) on chromosome 3. The CCBP2 and RPN1 region is located near GATA binding protein2 gene that has been previously shown to be associated with coronary heart disease. On chromosome 9, we found a novel association in the prostaglandin reductase 1 gene (P-value = 2.29Ă10(â7), ÎČ = 0.16), which is downstream from lysophosphatidic acid receptor 1. This region has previously been shown to be associated with monocyte count. We also replicated monocyte associations of genome-wide significance (P-value = 5.68Ă10(â17), ÎČ = â0.23) at the integrin, alpha 4 gene on chromosome 2. The novel IRF8 results and further replications provide supporting evidence of genetic regions associated with monocyte count
Pauci-immune necrotizing and crescentic glomerulonephritis in a patient with systemic lupus erythematosus
We report a case of pauci-immune proliferative necrotizing and crescentic glomerulonephritis in a patient with systemic lupus erythematosus (SLE) who presented with a nephrotic syndrome, while SLE was clinically and serologically quiescent. Immunofluorescence and electron microscopy examination of the kidney biopsy failed to reveal any significant deposit of immunoglobulins as well as of complement C3 and C1q, excluding lupus nephritis as the determinant of crescentic glomerulonephritis. Anti-myeloperoxydase (MPO) as well as anti-proteinase 3 (PR3) antibodies were absent in the serum. An immunosuppressive regimen including corticosteroids and IV cyclophosphamide led to a dramatic decrease of proteinuria. We conclude that necrotizing glomerulonephritis unrelated to lupus nephritis may occur in a patient with quiescent SLE. An underlying dysfunction of cell-mediated immunity might explain the association of pauci-immune crescentic glomerulonephritis and SLE

Linkage to Primary Care and Survival After Hospital Discharge for HIV-Infected Adults in Tanzania
IntroductionLittle is known about outcomes after hospitalization for HIV-infected adults in sub-Saharan Africa. We determined 12-month, posthospital mortality rates in HIV-infected vs. uninfected adults and predictors of mortality.MethodsIn this prospective cohort study, we enrolled adults admitted to the medical wards of a public hospital in northwestern Tanzania. We conducted standardized questionnaires, physical examinations, and basic laboratory analyses including HIV testing. Participants or proxies were called at 1, 3, 6, and 12 months to determine outcomes. Predictors of in-hospital and posthospital mortality were determined using logistic regression. Cox regression models were used to analyze mortality incidence and associated factors. To confirm our findings, we studied adults admitted to another government hospital.ResultsWe enrolled 637 consecutive adult medical inpatients: 38/143 (26.6%) of the HIV-infected adults died in hospital vs. 104/494 (21.1%) of the HIV-uninfected adults. Twelve-month outcomes were determined for 98/105 (93.3%) vs. 352/390 (90.3%) discharged adults, respectively. Posthospital mortality was 53/105 (50.5%) for HIV-infected adults vs. 126/390 (32.3%) for HIV-uninfected adults (adjusted P = 0.006). The 66/105 (62.9%) HIV-infected adults who attended clinic within 1 month after discharge had significantly lower mortality than the other HIV-infected adults [adjusted hazards ratio = 0.17 (0.07-0.39), P < 0.001]. Adults admitted to a nearby government hospital had similar high rates of posthospital mortality.ConclusionsPosthospital mortality is disturbingly high among HIV-infected adult inpatients in Tanzania. The posthospital period may offer a window of opportunity to improve survival in this population. Interventions are urgently needed and should focus on increasing posthospital linkage to primary HIV care
Fine-needle aspiration for diagnosis of tuberculous lymphadenitis in children in Bangui, Central African Republic
N2 - BACKGROUND: Tuberculosis (TB) is a major cause of childhood morbidity and mortality in developing countries. One of the main difficulties is obtaining adequate specimens for bacteriological confirmation of the disease in children.The aim of this study is to evaluate the adequacy of fine-needle aspiration (FNA) for the diagnosis of TB. METHODS: In a prospective study conducted at the paediatric hospital in Bangui in 2007--2009, we used fine-needle aspiration to obtain samples for diagnosis of TB from 131 children aged 0--17 years with persistent lymphadenitis. RESULTS: Fine-needle aspiration provided samples that could be used for bacteriological confirmation of TB. Ziehl-Neelsen staining for acid-fast bacilli was positive in 42.7% of samples, and culture identified TB in 67.2% of cases. Of 75 samples that were stain-negative, 49 (65.3%) were culture-positive, while 12 stain-positive samples remained culture-negative. Ten of the 12 stain-positive, culture-negative samples were from patients who had received previous antimicrobial therapy. With regard to phenotypic drug susceptibility, 81/88 strains (91.1%) were fully susceptible to isoniazid, rifampicin, ethambutol and streptomycin, six (6.8%) were resistant to one drug, and one multidrug-resistant strain was found. CONCLUSIONS: Fine-needle aspiration is simple, cost-effective and non-invasive and can be performed by trained staff. Combined with rapid molecular diagnostic tests, fine-needle aspirates could improve the diagnosis of TB and provide valuable information for appropriate treatment and drug resistance
