When we evaluated the effect of reconstructed prairie strips on bees in the context of the surrounding landscape, we found that these conservation practices had positive effects on bees in agriculturally-dominated areas and that these effects were detectable in low to high complexity landscapes with 8-69% natural habitat. In landscapes dominated by crops with few pollen and nectar resources the inclusion of native prairie strips can buffer the decline of bees and effectively increase bee abundance and diversity.Decreasing the cost of high-throughput DNA sequencing technologies, provides a huge amount of data that enables researchers to determine haplotypes for diploid and polyploid organisms. Although various methods have been developed to reconstruct haplotypes in diploid form, their accuracy is still a challenging task. Also, most of the current methods cannot be applied to polyploid form. In this paper, an iterative method is proposed, which employs hypergraph to reconstruct haplotype. The proposed method by utilizing chaotic viewpoint can enhance the obtained haplotypes. For this purpose, a haplotype set was randomly generated as an initial estimate, and its consistency with the input fragments was described by constructing a weighted hypergraph. Partitioning the hypergraph specifies those positions in the haplotype set that need to be corrected. This procedure is repeated until no further improvement could be achieved. Each element of the finalized haplotype set is mapped to a line by chaos game representation, and a coordinate series is defined based on the position of mapped points. Then, some positions with low qualities can be assessed by applying a local projection. Experimental results on both simulated and real datasets demonstrate that this method outperforms most other approaches, and is promising to perform the haplotype assembly.
Until a vaccine is developed, a test, trace and isolate strategy is the most effective method of controlling the COVID-19 outbreak. Contact tracing and case isolation are common methods for controlling infectious disease outbreaks. However, the effectiveness of any contact tracing system rests on public engagement. Numerous factors may influence an individual’s willingness to engage with a contact tracing system. Understanding these factors has become urgent during the COVID-19 pandemic.
To identify facilitators and barriers to uptake of, and engagement with, contact tracing during infectious disease outbreaks.
A rapid systematic review was conducted to identify papers based on primary research, written in English, and that assessed facilitators, barriers, and other factors associated with the uptake of, and engagement with, a contact tracing system.
Four themes were identified as facilitators to the uptake of, and engagement with, contact tracing collective responsibility; personal benefit; co-production of contact tracing systems; and the perception of the system as efficient, rigorous and reliable. Five themes were identified as barriers to the uptake of, and engagement with, contact tracing privacy concerns; mistrust and/or apprehension; unmet need for more information and support; fear of stigmatization; and mode-specific challenges.
By focusing on the factors that have been identified, contact tracing services are more likely to get people to engage with them, identify more potentially ill contacts, and reduce transmission.

The overwhelmed health care systems and the strict social containment measures have had an impact on the threshold at which patients seek medical care for diseases other than COVID-19, including cardiovascular conditions.Dear Editor, I would like to share ideas on the publication by Olivares- Gazca et al.1, titled Infusion of convalescent plasma is associated with clinical improvement in critically ill patients with COVID-19 A pilot study. The authors stated that “although other treatment were also administered to the patients and as a result data are difficult to interpret, it seems that the addition of CoPla improved pulmonary function1.” In fact, it is possible that convalescent plasma therapy might be useful in management of the COVID-19 patients.
The best timing of peritoneal dialysis (PD) initiation after catheter implantation is still controversial. It is necessary to explore whether there exists a waiting period to minimize the risk of complications.
A systematic review and meta-analysis were searched in multiple electronic databases published from inception to February 29, 2020, to identify cohort studies for evaluating the outcome and safety of unplanned-start PD (<14 days after catheter insertion). see more Risks of bias across studies were evaluated using Newcastle-Ottawa Quality Assessment Scale.
Fourteen cohort studies with a total of 2,401 patients were enrolled. We found that early-start PD was associated with higher prevalence of leaks (RR 2.67, 95% CI, 1.55-4.61) and omental wrap (RR 3.28, 95% CI, 1.14-9.39). Furthermore, patients of unplanned-start PD in APD group have higher risk of leaks, while those in CAPD group have a higher risk of leaks, omental wrap, and catheter malposition. In shorter break-in period (BI) group, the risk of sufg early technical survival, which may not be associated with infectious complications. Rigorous studies are required to be performed.
The evolution and prognostic impact of loop diuretic efficiency according to chronic kidney disease (CKD) severity is unclear.
This retrospective cohort study includes 783 CKD patients on oral loop diuretic therapy with a 24-h urine collection available. Acute kidney injury and history of renal replacement therapy were exclusion criteria. Patients were stratified according to Kidney Disease Improving Global Outcomes (KDIGO) glomerular filtration rate class. Loop diuretic efficiency was calculated as urine output, natriuresis, and chloruresis, each adjusted for loop diuretic dose, and compared among strata. Risk for onset of dialysis and all-cause mortality was evaluated.
Loop diuretic efficiency metrics decreased from KDIGO class IIIB to IV in furosemide users and from KDIGO class IV to V with all loop diuretics (p value <0.05 for all comparisons). The correlation between loop diuretic efficiency and creatinine clearance was moderate at best (Spearman’s ρ 0.298-0.436; p value <0.001 for all correlations).
