RESULTS Children under surveillance contributed to 126,657 child years of observations. Sixty-three thousand three hundred eighty-four illness episodes were assessed in the UHCs. Blood specimens were collected from 8,668 suspected IPD cases and CSF from 177 suspected meningitis cases. Streptococcus pneumoniae was isolated from 46 cases; 32 (70%) were vaccine serotype. The population-based incidence of IPD was 36.3/100,000 child years of observations. About 80% of the cases occurred in children below two years of age. DISCUSSION IPD was common in rural Bangladesh suggesting the potential benefit of an effective vaccine. Measurement of the burden of IPD requires multiple surveillance modalities.A fluorescence marker mOrange was inserted to the popular pLentiCrispr-V2 to create pLentiCrispr-V2-mOrange (V2mO) that contained both a puromycin selection and a fluorescent marker, making viral production and target transduction visible. Lentiviruses packaged with this plasmid and appropriate guide RNAs (gRNAs) successfully knocked out the genes RhoA, Gli1, and Gal3 in human gastric cancer cell lines. Cas9-gRNA editing efficiency could be estimated directly from Sanger electropherograms of short polymerase chain reaction products around the gRNA regions in Cas9-gRNA transduced cells. Single cloning of transduced target cell pools must be performed to establish stable knockout clones. Rescue of wildtype (RhoA and Gal3) and mutant (RhoA.Y42C) genes into knockout cells was successful only when cDNAs, where gRNAs bind, were modified by three nucleotides while the amino acid sequences remained unchanged. Stringent on-target CRISPR/Cas9 editing was observed in Gal3 gene, but not in RhoA gene since RhoA.Y42C already presented a nucleotide change in gRNA5 binding site. In summary, our improved strategy added these advantages adding visual marker to the popular lentiviral system, monitoring lentiviral production and transduction efficiencies, cell-sorting Cas9+ cells in target cells by fluorescence-activated cell sorting, direct estimation of gene editing efficiency of target cell pools by short PCR electropherograms around gRNA binding sites, and successful rescue of wildtype and mutant genes in knockout cells, overcoming Cas9 editing by modifying cDNAs.BACKGROUND CMV infection of the fetus or neonate can lead to devastating disease, and there are no effective prevention strategies to date. Vitamin D is a potent immunomodulator, supports antiviral immune responses, and plays an important role in placental immunity. METHODS Retrospective cohort study to evaluate the impact of low maternal vitamin D on congenital and early postnatal transmission of CMV among HIV-infected, non-breastfeeding women and their HIV exposed but negative infants from an urban HIV clinic. Vitamin D panel was performed on stored maternal plasma obtained near time of delivery. Infant CMV testing at 0-6 months included urine and oral cultures, and/or serum polymerase chain reaction testing. RESULTS Cohort included 340 mother-infant pairs (births 1991-2014). Among 38 infants (11%) with a CMV+ test between 0-6 months, 4.7% (14/300) had congenital CMV transmission (CMV+ test 0-3 weeks), and 7.6% (24/315) had peri/postnatal CMV (CMV+ test >3 weeks-6 months). Women with lower calcitriol (1,25-dihydroxyvitamin D), the active form of vitamin D, were more likely to have an infant with congenital (OR 12.2 [95% CI 1.61-92.2] P = 0.02) and peri/postnatal (OR 9.84 [95% CI 2.63-36.8] P = 0.0007) infections in multivariate analyses, independent of maternal HIV viral load and CD4 count. CONCLUSION This study demonstrates an association between inadequate maternal calcitriol during pregnancy and increased congenital and early postnatal acquisition of CMV among non-breastfeeding women with HIV and their HIV negative infants.OBJECTIVE Fluid overload is common among critically ill patients and is associated with worse outcomes. We aimed to assess the effect of diuretics on urine output, vasopressor dose, acute kidney injury (AKI) incidence, and need for renal replacement therapies (RRT) among patients who receive vasopressors. PATIENTS AND METHODS This is a single-center retrospective study of all adult patients admitted to the intensive care unit between January 2006 and December 2016 and received >6 hours of vasopressor therapy and at least one concomitant dose of diuretic. We excluded patients from cardiac care units. Hourly urine output and vasopressor dose for 6 hours before and after the first dose of diuretic therapy was compared. Rates of AKI development and RRT initiation were assessed with a propensity-matched cohort of patients who received vasopressors but did not receive diuretics. RESULTS There was an increasing trend of prescribing diuretics in patients receiving vasopressors over the course of the study. We includencidence, and need for renal replacement therapy.BACKGROUND Serum vitamin D insufficiency is a public health issue, especially among older women. Sun exposure is fundamental in the production of vitamin D, but older women have less optimal sun exposure. Linsitinib order Therefore, factors such as body composition and diet become more essential in sustaining sufficient serum levels of vitamin D. The objective of the current study is to determine factors contributing towards serum vitamin D insufficiency among 214 older women. METHODS The respondents had their body weight, height, waist circumference and body fat percentage measured, as well as interviewed for their socio-demographic characteristics, sun exposure and dietary intake. Fasting blood samples were obtained from the respondents to measure their serum 25-hydroxyvitamin D [25(OH)D] concentration. RESULTS There were 82.7% (95% CI 77.6%, 87.8%) of the respondents that had serum vitamin D insufficiency ( less then 50 nmol/L) with an average of 37.4 ± 14.3nmol/L. In stepwise multiple linear regression, high percentage of body fat (ß = -0.211, p less then 0.01) and low consumption of milk and dairy products (ß = 0.135, p less then 0.05) were the main contributors towards insufficient serum vitamin D levels, but not socio-demographic characteristics, other anthropometric indices, sun exposure and diet quality. CONCLUSION Older women with high body fat percentage and low dairy product consumption were more likely to have serum vitamin D insufficiency. Older women should ensure their body fat percentage is within a healthy range and consume more milk and dairy products in preventing serum vitamin D insufficiency.
