Subacute sclerosing panencephalitis: case based review

Subacute sclerosing panencephalitis (SSPE) is a chronic debilitating condition that occurs in children affected with measles. SSPE is broadly distinguished as typical SSPE, the more rampant form, occurring over a period of years following primary measles infection, while the atypical has a more rapidly progressive course over weeks to months. SSPE can present with cognitive, epileptic, autonomic, pyramidal and ophthalmologic manifestations with scholastic decline being the primary feature. The management of SSPE focuses on improvement of quality of life and prolongation of survival which can be achieved with the use of supportive care modalities and immunomodulators respectively. This is a comprehensive review which discusses several parameters of SSPE such as epidemiology, pathophysiology, clinical presentations, and detailed management protocol for this condition. As part of this review, we also discuss a case of rapidly progressive, fulminant and atypical SSPE in a five-year-old male presenting clinically with myoclonic jerks of lower extremities

Knowledge, attitudes, and practices related to antibiotic use in Paschim Bardhaman District: A survey of healthcare providers in West Bengal, India

IntroductionAntibiotic misuse is widespread and contributes to antibiotic resistance, especially in less regulated health systems such as India. Although informal providers are involved with substantial segments of primary healthcare, their level of knowledge, attitudes, and practices is not well documented in the literature.ObjectivesThis quantitative study systematically examines the knowledge, attitudes, and practices of informal and formal providers with respect to antibiotic use.MethodsWe surveyed a convenience sample of 384 participants (96 allopathic doctors, 96 nurses, 96 informal providers, and 96 pharmacy shopkeepers) over a period of 8 weeks from December to February using a validated questionnaire developed in Italy. Our team created an equivalent, composite KAP score for each respondent in the survey, which was subsequently compared between providers. We then performed a multivariate logistic regression analysis to estimate the odds of having a low composite score (ResultsDoctors scored highest in questions assessing knowledge (77.3%) and attitudes (87.3%), but performed poorly in practices (67.6%). Many doctors knew that antibiotics were not indicated for viral infections, but over 87% (n = 82) reported prescribing them in this situation. Nurses, pharmacy shopkeepers, and informal providers were more likely to perform poorly on the survey compared to allopathic doctors (OR: 10.4, 95% CI 5.4, 20.0, pConclusionsOur findings indicate poor knowledge and awareness of antibiotic use and functions among informal health providers, and dissonance between knowledge and practices among allopathic doctors. The nexus between allopathic doctors, pharmaceutical company representatives, and informal health providers present promising avenues for future research and intervention

Community-based management of severe acute malnutrition in India: new evidence from Bihar.

BACKGROUND: An estimated one-third of the world's children who are wasted live in India. In Bihar state, of children -2 SDs and MUAC >110 mm. These variables changed in July 2010 to admission on the basis of an MUAC <115 mm and discharge at an MUAC ≥120 mm. Uncomplicated SAM cases were treated as outpatients in the community by using a WHO-standard, ready-to-use, therapeutic lipid-based paste produced in India; complicated cases were treated as inpatients by using F75/F100 WHO-standard milk until they could complete treatment in the community. RESULTS: A total of 8274 children were admitted including 5149 girls (62.2%), 6613 children aged 6-23 mo (79.9%), and 87.3% children who belonged to Scheduled Caste, Scheduled Tribe, or Other Backward Caste families or households. Of 3873 children admitted under the old criteria, 41 children (1.1%) died, 2069 children (53.4%) were discharged as cured, and 1485 children (38.3%) defaulted. Of 4401 children admitted under the new criteria, 36 children (0.8%) died, 2526 children (57.4%) were discharged as cured, and 1591 children (36.2%) defaulted. For children discharged as cured, the mean (±SD) weight gain and length of stay were 4.7 ± 3.1 and 5.1 ± 3.7 g · kg(-1) · d(-1) and 8.7 ± 6.1 and 7.3 ± 5.6 wk under the old and new criteria, respectively (P < 0.01). After adjustment, significant risk factors for default were as follows: no community referral for admission, more severe wasting on admission, younger age, and a long commute for treatment. CONCLUSIONS: To our knowledge, this is the first conventional CMAM program in India and has achieved low mortality and high cure rates in nondefaulting children. The new admission criteria lower the threshold for severity with the result that more children are included who are at lower risk of death and have a smaller WHZ deficit to correct than do children identified by the old criteria. This study was registered as a retrospective observational analysis of routine program data at http://www.isrctn.com as ISRCTN13980582

Simple and Effective Multi-Paragraph Reading Comprehension

We consider the problem of adapting neural paragraph-level question answering models to the case where entire documents are given as input. Our proposed solution trains models to produce well calibrated confidence scores for their results on individual paragraphs. We sample multiple paragraphs from the documents during training, and use a shared-normalization training objective that encourages the model to produce globally correct output. We combine this method with a state-of-the-art pipeline for training models on document QA data. Experiments demonstrate strong performance on several document QA datasets. Overall, we are able to achieve a score of 71.3 F1 on the web portion of TriviaQA, a large improvement from the 56.7 F1 of the previous best system.Comment: 11 pages, updated a referenc

Lived experiences of palliative care among people living with HIV/AIDS: a qualitative study from Bihar, India.

OBJECTIVES: This study aimed to assess the lived experiences of palliative care among critically unwell people living with HIV/AIDS (PLHA), caregivers and relatives of deceased patients. It also aimed to understand the broader palliative care context in Bihar. DESIGN: This was an exploratory, qualitative study which used thematic analysis of semistructured, in-depth interviews as well as a focus group discussion. SETTING: All interviews took place in a secondary care hospital in Patna, Bihar which provides holistic care to critically unwell PLHA. PARTICIPANTS: We purposively selected 29 participants: 10 critically unwell PLHA, 5 caregivers of hospitalised patients, 7 relatives of deceased patients who were treated in the secondary care hospital and 7 key informants from community-based organisations. RESULTS: Critically ill PLHA emphasised the need for psychosocial counselling and opportunities for social interaction in the ward, as well as a preference for components of home-based palliative care, even though they were unfamiliar with actual terms such as 'palliative care' and 'end-of-life care'. Critically unwell PLHA generally expressed preference for separate, private inpatient areas for end-of-life care. Relatives of deceased patients stated that witnessing patients' deaths caused trauma for other PLHA. Caregivers and relatives of deceased patients felt there was inadequate time and space for grieving in the hospital. While both critically ill PLHA and relatives wished that poor prognosis be transparently disclosed to family members, many felt it should not be disclosed to the dying patients themselves. CONCLUSIONS: Despite expected high inpatient fatality rates, PLHA in Bihar lack access to palliative care services. PLHA receiving end-of-life care in hospitals should have a separate dedicated area, with adequate psychosocial counselling and activities to prevent social isolation. Healthcare providers should make concerted efforts to inquire, understand and adapt their messaging on prognosis and end-of-life care based on patients' preferences

Combination Treatment for Visceral Leishmaniasis Patients Coinfected with Human Immunodeficiency Virus in India.

BACKGROUND: There are considerable numbers of patients coinfected with human immunodeficiency virus (HIV) and visceral leishmaniasis (VL) in the VL-endemic areas of Bihar, India. These patients are at higher risk of relapse and death, but there are still no evidence-based guidelines on how to treat them. In this study, we report on treatment outcomes of coinfected patients up to 18 months following treatment with a combination regimen. METHODS: This retrospective analysis included all patients with confirmed HIV-VL coinfection receiving combination treatment for VL at a Médecins Sans Frontières treatment center between July 2012 and September 2014. Patients were treated with 30 mg/kg body weight intravenous liposomal amphotericin B (AmBisome) divided as 6 equal dose infusions combined with 14 days of 100 mg/day oral miltefosine (Impavido). All patients were encouraged to start or continue on antiretroviral therapy (ART). RESULTS: 102 patients (76% males, 57% with known HIV infection, 54% with a prior episode of VL) were followed-up for a median of 11 months (interquartile range: 4-18). Cumulative incidence of all-cause mortality and VL relapse at 6, 12, and 18 months was 11.7%, 14.5%, 16.6% and 2.5%, 6.0%,13.9%, respectively. Cumulative incidence of poor outcome at 6, 12, and 18 months was 13.9%, 18.4%, and 27.2%, respectively. Not initiating ART and concurrent tuberculosis were independent risk factors for mortality, whereas no factors were associated with relapse. CONCLUSIONS: In this Bihar-based study, combination therapy appeared to be well tolerated, safe, and effective and may be considered as an option for treatment of VL in HIV coinfected patients

Visceral leishmaniasis and HIV co-infection in Bihar, India: long-term effectiveness and treatment outcomes with liposomal amphotericin B (AmBisome).

BACKGROUND: Visceral Leishmaniasis (VL; also known as kala-azar) is an ultimately fatal disease endemic in the Indian state of Bihar, while HIV/AIDS is an emerging disease in this region. A 2011 observational cohort study conducted in Bihar involving 55 VL/HIV co-infected patients treated with 20-25 mg/kg intravenous liposomal amphotericin B (AmBisome) estimated an 85.5% probability of survival and a 26.5% probability of VL relapse within 2 years. Here we report the long-term field outcomes of a larger cohort of co-infected patients treated with this regimen between 2007 and 2012. METHODS AND PRINCIPAL FINDINGS: Intravenous AmBisome (20-25 mg/kg) was administered to 159 VL/HIV co-infected patients (both primary infections and relapses) in four or five doses of 5 mg/kg over 4-10 days. Initial cure of VL at discharge was defined as improved symptoms, cessation of fever, improvement of appetite and recession of spleen enlargement. Test of cure was not routinely performed. Antiretroviral treatment (ART) was initiated in 23 (14.5%), 39 (24.5%) and 61 (38.4%) before, during and after admission respectively. Initial cure was achieved in all discharged patients. A total of 36 patients died during follow-up, including six who died shortly after admission. Death occurred at a median of 11 weeks (IQR 4-51) after starting VL treatment. Estimated mortality risk was 14.3% at six months, 22.4% at two years and 29.7% at four years after treatment. Among the 153 patients discharged from the hospital, 26 cases of VL relapse were diagnosed during follow-up, occurring at a median of 10 months (IQR 7-14) after discharge. After accounting for competing risks, the estimated risk of relapse was 16.1% at one year, 20.4% at two years and 25.9% at four years. Low hemoglobin level and concurrent infection with tuberculosis were independent risk factors for mortality, while ART initiated shortly after admission for VL treatment was associated with a 64-66% reduced risk of mortality and 75% reduced risk of relapse. SIGNIFICANCE: This is the largest cohort of HIV-VL co-infected patients reported from the Indian subcontinent. Even after initial cure following treatment with AmBisome, these patients appear to have much higher rates of VL relapse and mortality than patients not known to be HIV-positive, although relapse rates appear to stabilize after 2 years. These results extend the earlier findings that co-infected patients are at increased risk of death and require a multidisciplinary approach for long-term management

Prevalence and determinants of asymptomatic Leishmania infection in HIV-infected individuals living within visceral leishmaniasis endemic areas of Bihar, India

People living with HIV (PLHIV) have an increased risk of developing visceral leishmaniasis (VL) and poor outcomes compared to HIV negative individuals. Here, we aim to establish the prevalence and determinants of asymptomatic Leishmania infection (ALI) in a cohort of PLHIV in Bihar, India. We hoped to evaluate optimal diagnostic algorithms to detect ALI in PLHIV. We conducted a cross-sectional survey of PLHIV ≥18 years of age with no history or current diagnosis of VL or post kala-azar dermal leishmaniasis (PKDL) at anti-retroviral therapy centres within VL endemic districts of Bihar. ALI was defined as a positive rK39 enzyme-linked immunosorbent assay (ELISA), rK39 rapid diagnostic test (RDT) and/or quantitative polymerase chain reaction (qPCR). Additionally, the urinary Leishmania antigen ELISA was evaluated. Determinants for ALI were established using logistic regression and agreement between diagnostic tests calculated using Cohen’s Kappa. A total of 1,296 PLHIV enrolled in HIV care, 694 (53.6%) of whom were female and a median age of 39 years (interquartile range 33–46), were included in the analysis. Baseline prevalence of ALI was 7.4% (n = 96). All 96 individuals were positive by rK39 ELISA, while 0.5% (n = 6) and 0.4% (n = 5) were positive by qPCR and rK39 RDT, respectively. Negligible or weak agreement was seen between assays. Independent risk factors for ALI were CD4 counts <100 (OR 3.1; 95% CI 1.2–7.6) and CD4 counts 100–199 (OR = 2.1;95% CI:1.1–4.0) compared to CD4 counts ≥300, and a household size ≥5 (OR = 1.9;95% CI:1.1–3.1). A total of 2.2% (n = 28) participants were positive by Leishmania antigen ELISA, detecting 20 additional participants to the asymptomatic cohort. Prevalence of ALI in PLHIV in VL endemic villages in Bihar was relatively high. Using the Leishmania antigen ELISA, prevalence increased to 9.0%. Patients with low CD4 counts and larger household size were found to have significantly higher risk of ALI

Host Biomarkers Reflect Prognosis in Patients Presenting With Moderate Coronavirus Disease 2019: A Prospective Cohort Study

Efficient resource allocation is essential for effective pandemic response. We measured host biomarkers in 420 patients presenting with moderate coronavirus disease 2019 and found that different biomarkers predict distinct clinical outcomes. Interleukin (IL)-1ra, IL-6, IL-10, and IL-8 exhibit dose-response relationships with subsequent disease progression and could potentially be useful for multiple use-cases
