Background
Acute Respiratory Infections (ARI) are a leading cause of childhood mortality and morbidity. Malawi has high childhood mortality but limited data on the prevalence of disease in the community.Methods
A cross‐sectional study of children aged 0‐59 months. Health passports were examined for ARI diagnoses in the preceding 12 months. Children were physically examined for malnutrition or current ARI.Results
828 children participated. The annual prevalence of ARI was 32.6% (95% CI 29.3‐36.0%). Having a sibling with ARI (OR 1.44, P = .01), increasing household density (OR 2.17, P = .02) and acute malnutrition (OR 1.69, P = .01) were predictors of infection in the last year. The point prevalence of ARI was 8.3% (95% CI 6.8‐10.4%). Risk factors for current ARI were acute‐on‐chronic malnutrition (OR 3.06, P = .02), increasing household density (OR1.19, P = .05) and having a sibling with ARI (OR 2.30, P = .02).Conclusion
This study provides novel data on the high prevalence of ARI in Malawi. This baseline data can be used in the monitoring and planning of future interventions in this population. 相似文献3.

Micro‐ribonucleic acid‐binding site variants of type 2 diabetes candidate loci predispose to gestational diabetes mellitus in Chinese Han women 下载免费PDF全文

Aims/Introduction
Emerging evidence has suggested that the genetic background of gestational diabetes mellitus (GDM) was analogous to type 2 diabetes mellitus. In contrast to type 2 diabetes mellitus, the genetic studies for GDM were limited. Accordingly, the aim of the present study was to extensively explore the influence of micro‐ribonucleic acid‐binding single‐nucleotide polymorphisms (SNPs) in type 2 diabetes mellitus candidate loci on GDM susceptibility in Chinese.Materials and Methods
A total of 839 GDM patients and 900 controls were enrolled. Six micro‐ribonucleic acid‐binding SNPs were selected from 30 type 2 diabetes mellitus susceptibility loci and genotyped using TaqMan allelic discrimination assays.Results
The minor allele of three SNPs, PAX4 rs712699 (OR 1.366, 95% confidence interval 1.021–1.828, P = 0.036), KCNB1 rs1051295 (OR 1.579, 95% confidence interval 1.172–2.128, P = 0.003) and MFN2 rs1042842 (OR 1.398, 95% confidence interval 1.050–1.862, P = 0.022) were identified to significantly confer higher a risk of GDM in the additive model. The association between rs1051295 and increased fasting plasma glucose (b = 0.006, P = 0.008), 3‐h oral glucose tolerance test plasma glucose (b = 0.058, P = 0.025) and homeostatic model assessment of insulin resistance (b = 0.065, P = 0.017) was also shown. Rs1042842 was correlated with higher 3‐h oral glucose tolerance test plasma glucose (b = 0.056, P = 0.028). However, no significant correlation between the other included SNPs (LPIN1 rs1050800, VPS26A rs1802295 and NLRP3 rs10802502) and GDM susceptibility were observed.Conclusions
The present findings showed that micro‐ribonucleic acid‐binding SNPs in type 2 diabetes mellitus candidate loci were also associated with GDM susceptibility, which further highlighted the similar genetic basis underlying GDM and type 2 diabetes mellitus. 相似文献9.

Analysis of pancreatic volume in acute‐onset,slowly‐progressive and fulminant type 1 diabetes in a Japanese population 下载免费PDF全文

Aims/Introduction
A decrease in the size of the pancreas is observed in islet autoantibody‐positive non‐diabetic donors and acute‐onset type 1 diabetes irrespective of the diabetes duration. Little is known, however, about the relationship between the size of the pancreas and type 1 diabetes subtypes, including fulminant type 1 diabetes.Materials and Methods
We examined the pancreatic volume (PV) in 44 adult patients with type 1 diabetes (16 acute‐onset type 1 diabetes, 18 slowly progressive type 1 diabetes and 10 fulminant type 1 diabetes) and 39 age‐ and body mass index‐matched non‐diabetic controls. PV was measured by computed tomography. The ability to secrete insulin was assessed by stimulated C‐peptide after intravenous glucagon administration.Results
PV was significantly correlated with bodyweight in both control participants and type 1 diabetes patients. The PV index (PVI; PV/bodyweight) was decreased by 39% in type 1 diabetes compared with that in controls. PVI was significantly decreased in acute‐onset type 1 diabetes patients and slowly progressive type 1 diabetes patients (both P < 0.0001), but not in fulminant type 1 diabetes patients (P = 0.10), compared with control participants. In cases patients with recent‐onset type 1 diabetes (0–7 days post‐diagnosis), PVI was significantly decreased in acute‐onset type 1 diabetes patients (n = 8, P = 0.0005), but not in fulminant type 1 diabetes patients (n = 7, P = 0.44), compared with controls. PVI showed no correlations with the diabetes duration, C‐peptide levels, glycated hemoglobin, glutamic acid decarboxylase autoantibody levels, serum amylase or daily total insulin dose in type 1 diabetes subtypes.Conclusions
The present results show that patients with acute‐onset type 1 diabetes and slowly progressive type 1 diabetes have small pancreases irrespective of the diabetes duration or C‐peptide levels. In contrast to earlier findings on acute‐onset type 1 diabetes, we found no reduction of PVI at the onset of fulminant type 1 diabetes. 相似文献12.
Background
Intestinal colonization by Staphylococcus aureus among hospitalized patients has been associated with increased risk of staphylococcal infection and could potentially contribute to transmission. We hypothesized that S. aureus intestinal colonization is associated with increased frequency of S. aureus on patients' skin and nearby environmental surfaces. 相似文献13.

1 Background
T‐cell depletion (TCD) effectively reduces severe graft‐versus‐host disease in recipients of HLA‐mismatched allografts. However, TCD is associated with delayed immune recovery and increased infections. We hypothesized that specific depletion of CD45RA+ naive T cells, rather than broad depletion of CD3+ T cells, can preserve memory‐immunity in the allografts and confer protection against important viral infections in the early post‐transplant period.2 Methods
Sixty‐seven patients who received TCD haploidentical donor transplantation for hematologic malignancy on 3 consecutive trials were analyzed.3 Results
Patients receiving CD45RA‐depleted donor grafts had 2000‐fold more donor T cells infused, significantly higher T‐cell counts at Day +30 post transplant (550/μL vs 10/μL; P < .001), and higher T‐cell diversity by Vbeta spectratyping at Day +100 (P < .001). Importantly, these recipients experienced a significant reduction in both the incidence (P = .002) and duration (P = .02) of any viremia (cytomegalovirus, Epstein‐Barr virus, or adenovirus) in the first 6 months post transplant. Specifically, recipients of CD3‐depleted grafts were more likely to experience adenovirus viremia (27% vs 4%, P = .02).4 Conclusion
CD45RA‐depletion provided a large number of donor memory T cells to the recipients and was associated with enhanced early T‐cell recovery and protection against viremia. 相似文献15.
