Background: Pneumonia and diarrhoea are the leading causes of childhood mortality and morbidity worldwide. Recurrence of these common infections are one of the immediate causes of malnutrition, which puts children at risk of further infection. While studies have focused on how gut microbiota is broadly protective against respiratory infection, there has been less attention paid to the reverse relationship, of respiratory microbiota and pathogens influencing the gut, and subsequent association with growth. Methods: In this sub-study of a prospective cohort study, 27 children (2-24 months) who tested positive for Cryptosporidium were followed up over 8 weeks. Respiratory and stool pathogens were detected using quantitative molecular methods. Nutritional outcomes were assessed as length-for-age (LAZ), weight-for-length (WLZ) and weight-for-age (WAZ) z-scores. Changes over the study period were compared using repeated analysis of variance and mixed effects model analysis. Results: In this period,104 sputum and stool samples were collected. All stool samples had at least one pathogen detected, with an average of 5.1 (SD 2.1) stool pathogens, compared to 84% of the sputum samples with an average 3.5 (SD1.8). Diarrhoeagenic E. coli were the most common stool pathogens (92%), followed by Cryptosporidium (52%) and Campylobacter pan (39%). In sputum, S. pneumoniae was most prevalent (84%), seconded by Rhinovirus (56%) and M. catarrhalis (50%). There was a significant change in WAZ over the follow-up period. Children who had ≥3 GI pathogens had significantly a lower LAZ mean score at enrollment (-1.8 (SD 1.4)) and across the follow-up period. No relationship between respiratory pathogens and short-term growth was observed. Out of 49 sputum samples that had ≥3 pathogens, 42 (85%) simultaneously had ≥3 GI pathogens. Conclusion: Among young children hospitalized with diarrhoea, multiple gut and respiratory pathogens were prevalent over an 8-week follow-up period. The presence of more GI, but not respiratory, pathogens was significantly associated with reduced short-term growth.

Background: Diarrhea is a major contributor to childhood mortality and morbidity in the developing world. Objective: The study was aimed to determine the prevalence of Entamoeba histolytica among children diagnosed with acute diarrhea in Kura General Hospital Kano, from February to August 2017. Methodology: A total of 236 stools samples were collected from children within the age group of 0 – 5 years diagnosed with acute diarrhea attending the Hospital. The stool samples were examined for Entamoeba Histolytica cysts and trophozoites using direct wet preparation and Formol Ether concentration techniques. Results: The result showed that 23 samples which accounted for 9.75% of the samples were found to be positive for the parasite. Highest incidence of the parasite was found among children within the age category of 4 - 5 years. The results also indicated that males (56.5%) were more infected than females (43.5%). However, there is no statistical difference in the rate of infection among the sex and age group of the patients at p< 0.05. Conclusion: In conclusion, maintenance of personal hygiene and improved sanitation of the environment will indeed prevent contamination of food and water sources.

The Impact

Rotavirus A (RVA) vaccines succeeded in lowering the burden of acute gastroenteritis (AGE) worldwide, especially preventing severe disease and mortality. In 2019, Brazil completed 13 years of RVA vaccine implementation (Rotarix™) within the National Immunization Program (NIP), and as reported elsewhere, the use of Rotarix™ in the country has reduced childhood mortality and morbidity due to AGE. Even though both marketed vaccines are widely distributed, the surveillance of RVA causing AGE and the monitoring of circulating genotypes are important tools to keep tracking the epidemiological scenario and vaccines impact. Thus, our study investigated RVA epidemiological features, viral load and G and P genotypes circulation in children and adults presenting AGE symptoms in eleven states from three out of five regions in Brazil. By using TaqMan®-based one-step RT-qPCR, we investigated a total of 1536 stool samples collected from symptomatic inpatients, emergency department visits and outpatients from January 2018 to December 2019. G and P genotypes of RVA-positive samples were genetically characterized by multiplex RT-PCR or by nearly complete fragment sequencing. We detected RVA in 12% of samples, 10.5% in 2018 and 13.7% in 2019. A marked winter/spring seasonality was observed, especially in Southern Brazil. The most affected age group was children aged >24–60 months, with a positivity rate of 18.8% (p < 0.05). Evaluating shedding, we found a statistically lower RVA viral load in stool samples collected from children aged up to six months compared to the other age groups (p < 0.05). The genotype G3P[8] was the most prevalent during the two years (83.7% in 2018 and 65.5% in 2019), and nucleotide sequencing of some strains demonstrated that they belonged to the emergent equine-like G3P[8] genotype. The dominance of an emergent genotype causing AGE reinforces the need for continuous epidemiological surveillance to assess the impact of mass RVA immunization as well as to monitor the emergence of novel genotypes.

Background: The use of composite magnetic resonance imaging (MRI) measures has been suggested to better explain disability in patients with multiple sclerosis (MS). However, little is known about the utility of composite scores at the earliest stages of the disease. Objective: To investigate whether, in patients with clinically isolated syndrome (CIS), a composite MRI measure, rather than the single metrics, would explain conversion to MS and would better correlate with disability at baseline and at 1 year of follow-up. Methods: Corticospinal tract (CST), corpus callosum (CC) and optic radiation (OR) volume, fractional anisotropy (FA), and mean diffusivity (MD) values were measured in 27 CIS patients and 24 healthy controls (HCs). Z-scores of FA, MD, and tract volume measures were calculated in patients, based on the corresponding measures obtained from HCs, and then combined in a composite score for each tract. Correlations between Z-scores at baseline and both the Expanded Disability Status Scale (EDSS) at baseline and at follow-up (FU-EDSS) were investigated. Results: Only CST, CC, and OR composite scores as well as the CST volume were significantly associated with FU-EDSS ( p = 0.005, p = 0.007, p = 0.020, and p = 0.010, respectively). Conclusion: The combination of MRI measures rather than the individual metrics better captured the association between tissue damage in both the CC, OR and CST and short-term follow-up disability.

Abstract Abstract Background-Globally, acute malnutrition accounts for >50% cases of childhood mortality in under 5 children each year. Moderate acute malnutrition treatment would be to reduce child mortality and morbidity. Study done in Ethiopia showed treatment food share, lack of water and other factor suggested to cause lower chance of recovery at end of 16 week as per Ethiopian acute malnutrition treatment guide line. Methods- Retrospective cohort study design was conducted among children aged 6–59 months which were treated in targeted supplementary feeding program. A total of 402 children were selected from eight health posts by systematic random sampling. Data were collected by reviewing registration records and interview from January 1-10/2018. Data were analyzed using SPSS version 20, bivariate and multivariate statistical methods were used to analyze and describe the data and p < 0.05 was considered as significant. Results-the overall average timely recovery was 15 week (SD,3.3). Children treated by super cereal were 2.44 times more likely to recover timely than children treated by corn soybean blend (AHR 2.44; 95% CI 1.85-3.21). Children that had regular follows up has 48% (AHR 1.48; 95% CI 1.09-2.00) more chance of recovery than intermittent treatment follow up, children’s from sever food in secured family had 51% lower chance to recover than moderate food insecured house hold (AHR 0.49; 95% CI 0.21-0.11) and, admission MUAC³11.6 cm had 1.18 times higher proportion of recovery than admission MUAC = 11.5 cm (AHR 1.18; 95% CI 1.13-1.12). Children who have no transport access has 2 times lower proportion of recovery than who have access (AHR 0.5; 95% CI 0.38-0.64). Conclusion- the mean time to recovery was 15 week which is consistent with the national standard 16 weeks. Type of treatment foods, treatment follow up status, and admission mid upper arm circumference had significant association with time recovery moderate acute malnutrition treatment.

Purpose A significant relationship between verbal short-term memory (STM) and language performance in people with aphasia has been found across studies. However, very few studies have examined the predictive value of verbal STM in treatment outcomes. This study aims to determine if verbal STM can be used as a predictor of treatment success. Method Retrospective data from 25 people with aphasia in a larger randomized controlled trial of phonomotor treatment were analyzed. Digit and word spans from immediately pretreatment were run in multiple linear regression models to determine whether they predict magnitude of change from pre- to posttreatment and follow-up naming accuracy. Pretreatment, immediately posttreatment, and 3 months posttreatment digit and word span scores were compared to determine if they changed following a novel treatment approach. Results Verbal STM, as measured by digit and word spans, did not predict magnitude of change in naming accuracy from pre- to posttreatment nor from pretreatment to 3 months posttreatment. Furthermore, digit and word spans did not change from pre- to posttreatment or from pretreatment to 3 months posttreatment in the overall analysis. A post hoc analysis revealed that only the less impaired group showed significant changes in word span scores from pretreatment to 3 months posttreatment. Discussion The results suggest that digit and word spans do not predict treatment gains. In a less severe subsample of participants, digit and word span scores can change following phonomotor treatment; however, the overall results suggest that span scores may not change significantly. The implications of these findings are discussed within the broader purview of theoretical and empirical associations between aphasic language and verbal STM processing.

Summary. Background: To assess the impact of short- vs. long-term anticoagulation in addition to standard dual antiplatelet therapy (DAPT) upon endovascular treatment of (sub)acute thrombembolic occlusions of the lower extremity. Patient and methods: Retrospective analysis was conducted on 202 patients with a thrombembolic occlusion of lower extremities, followed by crirical limb ischemia that received endovascular treatment including thrombolysis, mechanical thrombectomy, or a combination of both between 2006 and 2015 at a single center. Following antithrombotic regimes were compared: 1) dual antiplatelet therapy, DAPT for 4 weeks (aspirin 100 mg/d and clopidogrel 75 mg/d) upon intervention, followed by a lifelong single antiplatelet therapy; 2) DAPT plus short term anticoagulation for 4 weeks, followed by a lifelong single antiplatelet therapy; 3) DAPT plus long term anticoagulation for > 4 weeks, followed by a lifelong anticoagulation. Results: Endovascular treatment was associated with high immediate revascularization (> 98 %), as well as overall and amputation-free survival rates (> 85 %), independent from the chosen anticoagulation regime in a two-year follow up, p > 0.05. Anticoagulation in addition to standard antiplatelet therapy had no significant effect on patency or freedom from target lesion revascularization (TLR) 24 months upon index procedure for both thrombotic and embolic occlusions. Severe bleeding complications occurred more often in the long-term anticoagulation group (9.3 % vs. 5.6 % (short-term group) and 6.5 % (DAPT group), p > 0.05). Conclusions: Our observational study demonstrates that the choice of an antithrombotic regime had no impact on the long-term follow-up after endovascular treatment of acute thrombembolic limb ischemia whereas prolonged anticoagulation was associated with a nominal increase in severe bleeding complications.
