Culture-independent analyses of microbial communities have progressed dramatically in the last decade, particularly due to advances in methods for biological profiling via shotgun metagenomics. Opportunities for improvement continue to accelerate, with greater access to multi-omics, microbial reference genomes, and strain-level diversity. To leverage these, we present bioBakery 3, a set of integrated, improved methods for taxonomic, strain-level, functional, and phylogenetic profiling of metagenomes newly developed to build on the largest set of reference sequences now available. Compared to current alternatives, MetaPhlAn 3 increases the accuracy of taxonomic profiling, and HUMAnN 3 improves that of functional potential and activity. These methods detected novel disease-microbiome links in applications to CRC (1262 metagenomes) and IBD (1635 metagenomes and 817 metatranscriptomes). Strain-level profiling of an additional 4077 metagenomes with StrainPhlAn 3 and PanPhlAn 3 unraveled the phylogenetic and functional structure of the common gut microbe Ruminococcus bromii, previously described by only 15 isolate genomes. With open-source implementations and cloud-deployable reproducible workflows, the bioBakery 3 platform can help researchers deepen the resolution, scale, and accuracy of multi-omic profiling for microbial community studies.Several studies have assessed the potential of essential oils as substitutes for synthetic pesticides, in order to counter insect resistance to commercial pesticides. Piper aduncum L. is a very common shrub in the Amazon Rainforest and in other subtropical areas. The objective of this review was to analyse the existing information on P. aduncum essential oil as a raw material for new bioproducts for sustainable pest disease management. With this review, we collected and critically analysed 59 papers, representing all the studies that aimed to evaluate the essential oil properties of this species as an insecticide, acaricide and antiparasitic. The chemical composition differs depending on the origin, although phenylpropanoid dillapiole is the most cited component, followed by myristicin, 1,8-cineole and β-ocimene. Between the acaricidal, antiparasitic and synergistic activities, the insecticidal effects are highly promising, with optimal results against the malaria vector Aedes aegypti, with an LC50 that ranges between 57 and 200μg/mL. Acaricidal activity has mainly been reported against Tetranychus urticae, showing an LC50 that ranges between 5.83 and 7.17μg/mL. Antiparasitic activity has predominately been found on Leishmania amazonensis, and antipromastigote activity has been found to be between 23.8 and 25.9μg/mL. Concerning the synergistic effect between dillapiole and synthetic insecticides, four studies on Spodoptera frugiperda found promising results with cypermethrin. In this review, we highlighted the potential of P. aduncum essential oil as a biopesticide, also focusing on the lack of information about applied research. We also provide suggestions for future investigations.Toxoplasma gondii is an obligate intracellular protozoan parasite that causes toxoplasmosis and threatens warm-blooded animal and human health worldwide. Simple and applicable diagnostic methods are urgently needed to guide development of effective approaches for prevention of toxoplasmosis. Most molecular diagnostic tools for T. gondii infection require high technical skills, sophisticated equipment, and a controlled lab environment. In this study, we developed a loop-mediated isothermal amplification-lateral-flow-dipstick (LAMP-LFD) assay that specifically targets the 529 bp for detecting T. gondii infection. This novel portable device is universal, fast, user-friendly, and guarantees experimental sensitivity as well as low risk of aerosol contamination. Our LAMP-LFD assay has a detection limit of 1 fg of T. gondii DNA, and shows no cross-reaction with other parasitic pathogens, including Cryptosporidium parvum, Leishmania donovani, and Plasmodium vivax. We validated the developed assay by detecting T. gondii in DNA extracted from blood samples collected from 318 stray cats and dogs sampled from Deqing, Wenzhou, Yiwu, Lishui and Zhoushan cities across Zhejiang province, Eastern China. The LAMP-LFD device detected T. gondii DNA in 4.76 and 4.69% of stray cats and dogs, respectively. In conclusion, the developed LAMP-LFD assay is efficient, minimizes aerosol contamination, and is therefore suitable for detecting T. gondii across basic medical institutions and field settings.Eimeria tenella is an obligate intracellular parasite that actively invades cecal epithelial cells of chickens. This parasite encodes a genome of more than 8000 genes. However, more than 70% of the gene models for this species are currently annotated as hypothetical proteins. In this study, a conserved hypothetical protein gene of E. tenella, designated EtCHP18905, was cloned and identified, and its immune protective effects were evaluated. The open reading frame of EtCHP18905 was 1053bp and encoded a protein of 350 amino acids with a molecular weight of 38.7kDa. The recombinant EtCHP18905 protein (rEtCHP18905) was expressed in E. coli. Using western blot, the recombinant protein was successfully recognized by anti GST-Tag monoclonal antibody and anti-sporozoites protein rabbit serum. Real-time quantitative PCR analysis revealed that the EtCHP18905 mRNA levels were higher in sporozoites than in unsporulated oocysts, sporulated oocysts and second-generation merozoites. Western blot analysis showed that EtCHP18905 protein expression levels were lower in sporozoites than in other stages. Immunofluorescence analysis indicated that the EtCHP18905 protein was located on the surface of sporozoites and second-generation merozoites. Inhibition experiments showed that the ability of sporozoites to invade host cells was significantly decreased after treatment with the anti-rEtCHP18905 polyclonal antibody. Vaccination with rEtCHP18905 protein was able to significantly decrease mean lesion scores and oocyst outputs as compared to non-vaccinated controls. The results suggest that the rEtCHP18905 protein can induce partial immune protection against infection with E. tenella and could be an effective candidate for the development of new vaccines.Physiologic changes during pregnancy may increase the risk of coronavirus disease 2019 (COVID-19) infection. Limited data show serious complications of COVID-19 infection and pregnancy. Severe adverse maternal and perinatal outcomes such as preterm delivery, intensive care unit admission, and neonatal and intrauterine death have been reported. Our knowledge of the epidemiology, pathogenesis, disease progression, and clinical course of COVID-19 is continually changing as more information and evidence emerge. The present case adds further insights on COVID-19 and anesthesia considerations for patients undergoing cesarean delivery. In this case report, we describe a successful spinal anesthetic in a pregnant woman with confirmed COVID-19. To prepare for the likelihood of caring for women during labor and cesarean delivery, anesthesia professionals must know how to provide safe, patient-centered care and how to protect every member of the obstetric team from exposure to the virus. In addition, it is paramount that our profession shares our experiences and practices to help guide our multidisciplinary approach in delivering the best care possible to these women.

Non-communicable diseases (NCDs) cause premature mortality among youth. Associated with lifestyle and behavioural choices, these diseases and deaths can and should be prevented among young people. This article presents data showing the gains in life expectancy among youth in the absence of NCD causes of death.

To estimate the levels of NCD mortality among youth (15 - 24 years of age) in South Africa (SA) and show the current and projected additional years of life gained with the elimination of heart disease, cancer and diabetes.

This was a cross-sectional study using 20 years of death notification forms from SA (1997 - 2016). see more The data were nationally representative and the sample was 62 395 youth deaths (age 15 - 24 years) from the selected NCDs. Cause-specific mortality rates, expressed as percentages, were estimated by age group and sex. Cause-deleted life-table techniques were used to estimate current and projected life expectancy (ex) and life expectancy in the absence of specific NCDs (e-ix).

Dea the SA healthcare system and to public health practitioners whose aim is to reduce the strain on public resources and reduce mortality among youth. Future studies should estimate the extent of NCD mortality in households and communities with the aim of developing macro-level interventions.

The quality of international normalised ratio (INR) control determines the effectiveness and safety of warfarin therapy. Data on INR control in non-metropolitan settings of South Africa (SA) are sparse.

To examine the time in therapeutic range (TTR) and its potential predictors in a sample of Garden Route District Municipality primary healthcare clinics (PHCs).

INR records from eight PHCs were reviewed. The TTR and percentage of patients with a TTR >65% were determined. A host of variables were analysed for association with TTR.

The median (interquartile range (IQR)) age of the cohort (N=191) was 56 (44 - 69) years. The median (IQR) TTR was 37.2% (20.2- 58.8); only 17.8% of patients had a TTR ≥65%. Compared with patients aged >50 years, those aged <50 had worse INR control (median (IQR) TTR 26.6% (16.1 - 53.0) v. 43.5% (23.5 - 60.1); p=0.01). Patients hospitalised for any reason during the study period had worse INR control than patients not hospitalised (median (IQR) TTR 26.2% (1e the quality of INR control in patients on warfarin therapy need to be instituted as a matter of urgency.

The association between pre-eclampsia and the subsequent development of metabolic syndrome has not been well documented in low- and middle-income countries.

To compare the prevalence of metabolic syndrome at 6 weeks after delivery among women with pregnancies complicated by pre-eclampsia with that in a normotensive, low-risk control group in an urban South African (SA) setting.

This was a prospective cohort study at two tertiary-level hospitals and one district-level hospital in Pretoria, SA. Women were recruited after delivery and were followed up 6 weeks later to confirm or exclude the diagnosis of metabolic syndrome.

Metabolic syndrome was diagnosed in 48/150 women with pregnancies complicated by pre-eclampsia (32.0%), compared with 33/150 (22.0%) of the control group (p=0.05).

Women who developed pre-eclampsia during pregnancy had an increased chance of metabolic syndrome being diagnosed 6 weeks after delivery. Guidelines should be developed to identify women with cardiometabolic risk, so that interventions may be implemented to modify this risk before and after pregnancy.
