Nitric oxide participates in waterlogging tolerance through enhanced adventitious root formation in the euhalophyte Suaeda salsa.

The interactions of NO and other signalling molecules contribute to adventitious root formation in many plant species. To our knowledge, the role of NO in the adventitious root formation of plants subjected to waterlogging are as yet unknown. Populations of Suaeda salsa L. , a C3 euhalophytic plant, from inland saline sites develop several adventitious roots in response to waterlogging. The NO donor sodium nitroprusside (SNP) and the NO scavenger 2-(4-carboxyphenyl)-4,4,5,5-tetramethyl-imidazoline-1-1-oxyl-3-oxide (cPTIO) were applied to S. salsa seedlings to examine the effects of NO on flooding tolerance and its possible mechanism. SNP alleviated growth inhibition and increased adventitious root formation, endogenous NO levels and adventitious root cell integrity in S. salsa subjected to waterlogging. These SNP-mediated effects were prevented by the extra application of cPTIO. SNP treatment decreased nitrate reductase activity but increased nitric oxide synthase (NOS) activity in adventitious roots. These results suggest that in S. salsa, NO participates in waterlogging tolerance by enhancing adventitious root formation and that NO generation is associated with the NOS-associated pathway.
Parental Awareness of Oral Health and Nutritional Behavior in Children with Congenital Heart Diseases Compared to Healthy Children

Parents of children with congenital heart disease (CHD) seem to underestimate the importance of optimized oral health. The low priority for a good oral hygiene and a healthy diet can be a risk factor for odontogenic bacteremia and infective endocarditis. The aim of this study was the evaluation of the disease awareness and dental knowledge of the parents using a questionnaire. Therefore, parents from 107 children with CHD and a healthy control group (HCG) consisting of 101 children both aged 2 to 6 years were asked to complete a questionnaire containing items about the general health, oral hygiene behavior, preventive measures, dental visits and intake of potential drinks and cariogenic nutrition of their child. The results of the present study show that the CHD group had a poorer oral health behavior than the HCG. Healthy children brushed their teeth significantly more often (65.4%) than the CHD children (45.1%). Only 75% of CHD children used fluorides in their daily life in comparison to 86.6% of the healthy children, 8.7% of their parents neglected completely fluoride supplementation. Of all CHD children 23.1% in comparison to 8.1% of the controls had never visited a dentist before. Furthermore, the daily consumption of cariogenic food and drinks was generally higher in the CHD group. These findings demonstrate a need for improvement in parental knowledge of the efficiency of different measures to improve dental health. This important oral health for CHD children from the early stage of life is obvious, especially regarding their risk for odontogenic bacteria and infective endocarditis.
Determination of Anatomical Levels in Spina Bifida Fetuses with Ultrasound and MRI

Abstract Purpose The goal of this study was to assess the accuracy of prenatal anatomical level determination by ultrasound (US) and magnetic resonance imaging (MRI) by analyzing the congruence with the “true” anatomical level identified by postnatal MRI. Patients and Methods The first 60 patients undergoing fetal myelomeningocele surgery at The Zurich Center for Fetal Diangosis and Therapy were included in this study. Anatomical levels (i. e., first dysraphic vertebra) determined by prenatal US and MRI were compared to postnatal MRI. The level of agreement between the imaging modalities was evaluated with a Cohen’s kappa test. Results > 0.6 were interpreted as good agreement, > 0.8 as excellent. Results The exact congruence between prenatal US and MRI compared to postnatal MRI was 33 % and 48 %, respectively, for an accuracy within one level difference of 80 % and 90 %, and within two levels difference of 95 % and 98 %, respectively. The level of agreement of prenatal US and MRI compared to postnatal MRI was 0.62 and 0.79, respectively. Most of the prenatally incorrectly assigned levels were assigned too high (worse) than the “true” level (US 88 % vs. MRI 65 %). Conclusion Reliable exact prenatal level determination by US and MRI is not possible. However, the prenatal determination of the anatomical level of the lesion is good within one level margin of error. Prenatal US as well as MRI demonstrate a systematic error towards higher levels. The above considerations must be integrated into prenatal counselling.
Emulating a target trial in case-control designs: an application to statins and colorectal cancer.

BACKGROUND Previous case-control studies have reported a strong association between statin use and lower cancer risk. It is unclear whether this association reflects a benefit of statins or is the result of design decisions that cannot be mapped to a (hypothetical) target trial (that would answer the question of interest). METHODS We outlined the protocol of a target trial to estimate the effect of statins on colorectal cancer incidence among adults with low-density lipoprotein (LDL) cholesterol below 5 mmol/L. We then emulated the target trial using linked electronic health records of 752 469 eligible UK adults (CALIBER 1999-2016) under both a cohort design and a case-control sampling of the cohort. We used pooled logistic regression to estimate intention-to-treat and per-protocol effects of statins on colorectal cancer, with adjustment for baseline and time-varying risk factors via inverse-probability weighting. Finally, we compared our case-control effect estimates with those obtained using previous case-control procedures. RESULTS Over the 6-year follow-up, 3596 individuals developed colorectal cancer. Estimated intention-to-treat and per-protocol hazard ratios were 1.00 (95% confidence interval [CI]: 0.87, 1.16) and 0.90 (95% CI: 0.71, 1.12), respectively. As expected, adequate case-control sampling yielded the same estimates. By contrast, previous case-control analytical approaches yielded estimates that appeared strongly protective (odds ratio 0.57, 95% CI: 0.36, 0.91, for ≥5 vs. <5 years of statin use). CONCLUSIONS Our study demonstrates how to explicitly emulate a target trial using case-control data to reduce discrepancies between observational and randomized trial evidence. This approach may inform future case-control analyses for comparative effectiveness research.

Oxidative Stress and Inflammation in COVID-19-Associated Sepsis: The Potential Role of Anti-Oxidant Therapy in Avoiding Disease Progression

Since the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak emerged, countless efforts are being made worldwide to understand the molecular mechanisms underlying the coronavirus disease 2019 (COVID-19) in an attempt to identify the specific clinical characteristics of critically ill COVID-19 patients involved in its pathogenesis and provide therapeutic alternatives to minimize COVID-19 severity. Recently, COVID-19 has been closely related to sepsis, which suggests that most deceases in intensive care units (ICU) may be a direct consequence of SARS-CoV-2 infection-induced sepsis. Understanding oxidative stress and the molecular inflammation mechanisms contributing to COVID-19 progression to severe phenotypes such as sepsis is a current clinical need in the effort to improve therapies in SARS-CoV-2 infected patients. This article aims to review the molecular pathogenesis of SARS-CoV-2 and its relationship with oxidative stress and inflammation, which can contribute to sepsis progression. We also provide an overview of potential antioxidant therapies and active clinical trials that might prevent disease progression or reduce its severity.
Conservative Treatment for Acute Ankle Sprain: A Systematic Review

The aim was to identify conservative treatments available for acute ankle sprain and to evaluate their effectiveness with respect to pain relief and short-term recovery of functional capacity. A systematic review of the relevant literature was conducted via a data search of the PROSPERO, PubMed, Scopus, CINAHL, PyscINFO and SPORTDiscus databases, from inception until December 2019, focusing on randomised control trial studies. Two of the authors independently assessed the quality of each study located and extracted the relevant data. The quality of each paper was assessed using the Cochrane risk of bias tool included in RevMan 5. In all, 20 studies met the inclusion criteria. In terms of absence of bias, only nine papers were classed as “high quality”. Studies (75%) were of low quality in terms of the blinding of participants and personnel and uncertainty in blinding of outcome assessment and all presented one or more other forms of bias. Despite the generally low quality of the studies considered, it can be concluded that conservative treatment for acute ankle sprain normally achieves pain relief and rapidly improved functionality. Research based on higher-quality study designs and procedures would enable more definitive conclusions to be drawn.
Clinical manifestations and outcomes of COVID-19 in the paediatric population: a systematic review.

OBJECTIVE Coronavirus disease 2019 (COVID-19), the respiratory illness caused by severe acute respiratory syndrome coronavirus 2, has affected hundreds of thousands of people. We aim to report the distribution of cases, prevalence, and clinical, radiological, and laboratory signs and outcomes of COVID-19 in paediatric patients. Moreover, we intend to evaluate neonatal clinical outcomes. Hence, our age range of interest is 0 to 19 years. METHODS A systematic literature review was conducted using the Medline database to identify papers published between 1 December 2019 and 9 April 2020 on COVID-19. RESULTS The search identified 27 relevant scientific papers and letters. The review showed that the prevalence of COVID-19 in the paediatric population accounts for a small percentage of patients, whose clinical signs and symptoms are often milder than those of adults. Despite better prognosis and low mortality in children, the disease can progress to severe pneumonia in some cases, especially in the presence of co-morbidities. Children are likely to become a hidden source of infection because of their atypical presentation, and they may play a role in community transmission, leading to unfavourable outcomes. There is little evidence about intrauterine vertical transmission. As no vaccine or specific antiviral is currently available, management plans include supportive treatment. CONCLUSION As compared with that in adults, the presentation of COVID-19 in children is mild and has a better prognosis. Sufficient evidence regarding the probability of intrauterine vertical transmission could not be found, and further studies need to be conducted to establish this relationship.
The Impact of a Virtual Radiology Medical Student Rotation: Maintaining Engagement During COVID-19 Mitigation

ABSTRACT Introduction The purpose of this study is to introduce a virtual radiology rotation curriculum that is being used to safely maintain medical student and intern education and engagement with the Department of Radiology at Walter Reed National Military Medical Center during coronavirus disease 2019 (COVID-19) mitigation. Materials and Methods The curriculum is designed as a 4-week block with each week representing one of the four highest yield radiology subspecialties for medical students; neuroradiology, thoracic radiology, body radiology, and musculoskeletal radiology. A subspecialist radiologist from each section was identified as a primary mentor and tasked with designing a daily schedule for medical students and interns. The first 2 months of virtual rotators were surveyed to assess the effectiveness of the course. Results Thirty-five of 41 rotators responded to the survey, a response rate of 85%. Thirty-one of 35 (89%) of the rotators gave this virtual elective rotation a positive rating, with 16 trainees scoring the course as 4 out of 5 and 15 trainees selecting 5 out of 5. Four respondents selected 3 out of 5. Five out of 5 respondents who had experienced an in-person radiology elective rotation before this virtual rotation rated the virtual elective as more educational than the in-person rotation. We found the 4-week subspecialist mentor-based structure to be highly versatile, allowing us to simultaneously accommodate multiple groups of full or partial block rotators throughout COVID-19 mitigation. Conclusion A virtual rotation curriculum is a viable method of maintaining medical student and intern education and engagement with the department of radiology during COVID-19 mitigation.
Screening of Lactobacillus plantarum subsp. plantarum with Potential Probiotic Activities for Inhibiting ETEC K88 in Weaned Piglets

For screening excellent lactic acid bacteria (LAB) strains to inhibit enterotoxigenic Escherichia coli (ETEC) K88, inhibitory activities of more than 1100 LAB strains isolated from different materials, and kept in the lab, were evaluated in this study. Nine strains with inhibition zones, at least 22.00 mm (including that of a hole puncher, 10.00 mm), and good physiological and biochemical characteristics identified by 16S DNA gene sequencing and recA gene multiple detection, were assigned to Lactobacillus (L.) plantarum subsp. plantarum (5), L. fermentum (1), L. reuteri (1), Weissella cibaria (1) and Enterococcus faecalis (1), respectively. As investigated for their tolerance abilities and safety, only strain ZA3 possessed high hydrophobicity and auto-aggregation abilities, had high survival rate in low pH, bile salt environment, and gastrointestinal (GI) fluids, was sensitive to ampicillin, and resistant to norfloxacin and amikacin, without hemolytic activity, and did not carry antibiotic resistance genes, but exhibited broad spectrum activity against a wide range of microorganisms. Antibacterial substance may attribute to organic acids, especially lactic acid and acetic acid. The results indicated that the selected strain L. plantarum subsp. plantarum ZA3 could be considered a potential probiotic to inhibit ETEC K88 in weaned piglets for further research.
Association of technologically assisted integrated care with clinical outcomes in type 2 diabetes in Hong Kong using the prospective JADE Program: A retrospective cohort analysis

Background Diabetes outcomes are influenced by host factors, settings, and care processes. We examined the association of data-driven integrated care assisted by information and communications technology (ICT) with clinical outcomes in type 2 diabetes in public and private healthcare settings. Methods and findings The web-based Joint Asia Diabetes Evaluation (JADE) platform provides a protocol to guide data collection for issuing a personalized JADE report including risk categories (1–4, low–high), 5-year probabilities of cardiovascular-renal events, and trends and targets of 4 risk factors with tailored decision support. The JADE program is a prospective cohort study implemented in a naturalistic environment where patients underwent nurse-led structured evaluation (blood/urine/eye/feet) in public and private outpatient clinics and diabetes centers in Hong Kong. We retrospectively analyzed the data of 16,624 Han Chinese patients with type 2 diabetes who were enrolled in 2007–2015. In the public setting, the non-JADE group (n = 3,587) underwent structured evaluation for risk factors and complications only, while the JADE (n = 9,601) group received a JADE report with group empowerment by nurses. In a community-based, nurse-led, university-affiliated diabetes center (UDC), the JADE-Personalized (JADE-P) group (n = 3,436) received a JADE report, personalized empowerment, and annual telephone reminder for reevaluation and engagement. The primary composite outcome was time to the first occurrence of cardiovascular-renal diseases, all-site cancer, and/or death, based on hospitalization data censored on 30 June 2017. During 94,311 person-years of follow-up in 2007–2017, 7,779 primary events occurred. Compared with the JADE group (136.22 cases per 1,000 patient-years [95% CI 132.35–140.18]), the non-JADE group had higher (145.32 [95% CI 138.68–152.20]; P = 0.020) while the JADE-P group had lower event rates (70.94 [95% CI 67.12–74.91]; P < 0.001). The adjusted hazard ratios (aHRs) for the primary composite outcome were 1.22 (95% CI 1.15–1.30) and 0.70 (95% CI 0.66–0.75), respectively, independent of risk profiles, education levels, drug usage, self-care, and comorbidities at baseline. We reported consistent results in propensity-score–matched analyses and after accounting for loss to follow-up. Potential limitations include its nonrandomized design that precludes causal inference, residual confounding, and participation bias. Conclusions ICT-assisted integrated care was associated with a reduction in clinical events, including death in type 2 diabetes in public and private healthcare settings.
Human-Animal Interaction and the Emergence of SARS-CoV-2

The COVID-19 pandemic has affected all sectors of society, from health and economics to socialization and travel. The level and extent of this impact are unprecedented. Although the cause of COVID-19 was quickly identified to be a new coronavirus (SARS-CoV-2), the world was poorly prepared for preventing its spread. One important pillar of preparedness is surveillance of the sources of emerging pathogens and responding appropriately to prevent their spread in the human population. The ever-increasing interaction between humans and animals is one leading factor in facilitating the emergence of new pathogens. In this viewpoint, we discuss the possibility of the zoonotic origin of SARS-CoV-2, highlight the importance of understanding human-animal interaction to improve preparedness for future outbreaks, and outline recommendations for prevention.
Recent Advances in Matrix Metalloproteinase Research

マトリックスメタロプロテアーゼ (MMPs) と名付けられた、互いに性質のよく似た幾つかの結合組織分解金属プロテアーゼは、組織に存在する細胞や、炎症時の炎症細胞や腫瘍細胞から、活性のないプロ酵素として分泌され、活性化を受けてから多くの結合組織成分を分解出来るようになる。 cDNA配列の分析から、これらのプロテアーゼが数個のモジュールからなり、その中の幾つかはマトリックスタンパクから由来していることが明らかとなった。 MMPsに対して特異的な一群の組織性阻害物質 (TIMPs) がMMPsの細胞外での活性を調節している。 細胞に於けるMMPsとTIMPsは成長因子類、ホルモン、細胞の形態変化などによって別々に調節されている。 最近、レクチンもまたヒト線維芽細胞の系で、MMP発現を励起し、TIMP量を抑制することが示された。 この結果は、天然に存在するレクチンもまた in vivo でMMPとTIMP遺伝子発現の調節にたずさわっているかも知れないことを示している。
Current distribution and population size of the Blue Swallow Hirundo atrocaerulea in the southern Tanzanian highlands

Two surveys of Blue Swallows were conducted in the southern Tanzanian highland grasslands in order to determine the habitat preferences and estimate the size of this subpopulation. During the 2008/09 and 2012 surveys, a total distance of 3 635 km was travelled in search of Blue Swallows (at an altitude of above 1 400 m above sea level). Blue Swallows showed no preference for any altitude range above 1 400 m. The Blue Swallows showed a preference for natural pastures and for rural villages interspersed with crops and natural pasture. The buildings in the rural villages provide the nesting sites and, in close proximity, the crops, natural pastures, livestock and their dung possibly provide the food source for the aerial arthropods on which the Blue Swallows feed. In total, 151 Blue Swallows were recorded consisting of 62 males, 68 females and 21 unsexed individuals at 62 localities. These data along with environmental variables were used to construct an ecological niche model for the Blue Swallow. It was estimated that a mean of 12 791 km2 of suitable habitat was available for Blue Swallows. The 151 Blue Swallows recorded within the maximum perpendicular distance of 262 m on either side of the survey route resulted in a subpopulation estimate of 1 014 (338 to 507 pairs) Blue Swallows in the southern Tanzanian highland grasslands (12 791 km2). Mean densities were 0.023 to 0.035 pairs km − 2. A density of 0.13 pairs km − 2 recorded on a cattle farm consisting primarily of grasslands and wetlands was similar to the density of pairs found on sites in South Africa and Swaziland of compara- ble size and with matching characteristics to this site in Tanzania. Based on this new information the global Blue Swallow population estimate is updated to between 1 169 and 1 338 pairs.
Equipotency of insulin glargine 300 and 100 U/mL with intravenous dosing but differential bioavailability with subcutaneous dosing in dogs

Insulin glargine 300 U/mL (Gla‐300) contains the same units versus glargine 100 U/mL (Gla‐100) in three‐fold lower volume, and higher subcutaneous (SC) doses are required in people with diabetes. To investigate blood glucose (BG) lowering potency, Gla‐300 and Gla‐100 were compared after intravenous (IV, for 4 h) and SC (for 24 h) injection in healthy Beagle dogs.
Determination of Glyphosate in Water from a Rural Locality in México and Its Implications for the Population Based on Water Consumption and Use Habits

Glyphosate is a broad-spectrum herbicide widely used worldwide. Indeed, it is the herbicide most applied to all Mexican crops. Due to the overuse and poor disposal of the waste, this herbicide can reach the aquatic environments such as groundwater and surface water. Thus, there is a clear need to implement monitoring and surveillance programs for evaluating and controlling the exposure to this herbicide in rural populations. The goal of this study was to quantify the presence of glyphosate in different water bodies (groundwater, surface and drinking water) as well as to identify the uses and managements of water resources by rural communities to evaluate the potential human exposure to glyphosate in the Tenampulco region of the Mexican state of Puebla. Measurements were performed by a rapid and cost-effective ELISA-based method in groundwater and surface water from various sampling sites of the Tenampulco region. Glyphosate was detected in all groundwater samples to be below the maximum limit for glyphosate in water in Mexico. Nevertheless, these results indicate an exposure of glyphosate in these agricultural communities and the need to establish a monitoring program.
