ABSTRACT

CONTEXT: Children with critical CHD are at risk for neurodevelopmental impairments, including delays in expressive and receptive language development. However, no study has synthesised the literature regarding language abilities in children with this condition.

OBJECTIVE: We summarised the literature regarding expressive and receptive language in preschool children with critical CHD.

DATA SOURCES: MEDLINE, Embase, Scopus, Child Development and Adolescent Studies, ERIC, PsycINFO, and CINAHL.

STUDY SELECTION: We included studies published between January, 1990 and 1 July, 2021, focused on children aged ≤5 years with critical CHD requiring a complex cardiac procedure at age <1 year. Language ability was documented using standardised, validated tools assessing both expressive and receptive language outcomes.

DATA EXTRACTION: Data (study, patient and language characteristics, and results) were extracted by two reviewers.

RESULTS: Seventeen studies were included. Among children 2-5 years old with critical CHD, there were statistically significant deficits in overall (standardised mean difference: -0.46; 95 % confidence interval: -0.56, -0.35), expressive (standardised mean difference: -0.45;95 % confidence interval: -0.54, -0.37), and receptive (standardised mean difference: -0.32; 95 % confidence interval: -0.40, -0.23) language compared to normative data. Results reported as medians were similar to meta-analysis findings. Subgroup analysis showed that children with univentricular physiology had lower language scores than children with biventricular physiology.

CONCLUSIONS: Preschool children with critical CHD had statistically significantly lower language outcomes compared to expected population norms. Healthcare professionals should test early and often for language deficits, referring to individually tailored supports.

ABSTRACT

Genetic variation is the basis of selection, evolution and breeding. Maize landraces represent a rich source of allelic diversity, but their efficient utilization in breeding and research has been hampered by their heterogeneous and heterozygous nature and insufficient information about most accessions. While molecular inventories of germplasm repositories are growing steadily, linking these data to meaningful phenotypes for quantitative traits is challenging. Here, we present comprehensive molecular and phenotypic data for ∼1,000 doubled-haploid (DH) lines derived from three pre-selected European maize landraces. Due to their full homozygosity, the DH lines can be multiplied ad libitum and represent a powerful biological resource available to the community. The DH lines allow high-precision phenotyping in repeated experiments and reveal the full additive genetic variance of the population. The DH lines were evaluated for nine agronomically important, quantitative traits in multi-environment field trials comprising seven locations and two years. The DH populations revealed high genetic variance and high heritability for the analysed traits. The DH lines were genotyped with 600k SNP markers. After stringent quality filtering 500k markers remained for further analyses. This is the largest resource of landrace derived DH material in maize, unprecedented in its structure and dimension. The presented data are ideal for linking molecular variation to meaningful phenotypes. They can be used for genome-wide association studies, genomic prediction, and population genetic analyses as well as for developing and testing statistical methods. All plant material is available to the community for conducting additional experiments, extending the panel of traits and environments, and for testing the landrace-derived lines in combination with other genetic material.

ABSTRACT

PURPOSE: To characterize the clinical outcomes of a novel ab interno minimally invasive procedure with the STREAMLINE^® Surgical System for creation of incisional goniotomies and canal of Schlemm viscodilation in eyes with mild to severe primary open-angle glaucoma (POAG).

METHODS: In a prospective, single-arm, first-in-human case series, 20 eyes of 20 subjects with mild to severe POAG underwent creation of incisional goniotomies and canal of Schlemm viscodilation following phacoemulsification cataract extraction after washout of all intraocular pressure (IOP)-lowering medications. The angle surgery portion was performed with a single-use handpiece tipped with a microcannula that creates precise goniotomies through the trabecular meshwork into the canal of Schlemm and delivers a small volume of ophthalmic viscosurgical device directly into the canal via precise catheterization. Outcomes in this interim analysis included mean reduction in IOP and medications through 6 months of follow-up, as well as the proportion of eyes achieving IOP reduction ≥20% from baseline.

RESULTS: At month 6, mean IOP reduction of ≥20% from baseline was achieved in 89.5% of eyes (17/19). Mean (standard deviation) medicated IOP at screening was 16.3 (3.6) mmHg and unmedicated baseline IOP (after washout) was 23.5 (2.5) mmHg. Mean IOP was significantly reduced from baseline through 6 months of follow-up to 14.7 (2.4) mmHg (p<0.001), representing an IOP reduction of 8.8 mmHg (36.9%). Overall, 57.9% (11/19) of eyes decreased dependence on IOP-lowering medications by at least one medication, and 42.1% (8/19) were medication free. Mean medication use was reduced from 2.0 (0.8) at screening to 1.1 (1.1) at 6 months (p<0.001). Three eyes had transient IOP spikes treated with topical medications.

CONCLUSION: The creation of incisional goniotomies and canal of Schlemm viscodilation safely and effectively reduced IOP and the need for IOP-lowering medications by both clinically and statistically significant magnitudes in eyes with mild to severe POAG undergoing concomitant phacoemulsification cataract extraction through the first 6 months of follow-up.

ABSTRACT

The investigation of cancellous bone using ultrasound measurements is not an easy task due to the solid complex trabecular structure filled with fluid-like bone marrow. It is expected that the ultrasound propagated in cancellous bone contains valuable information about the complex structure. In this chapter, the methods to derive useful information by the two-wave phenomenon-based ultrasonic assessment of cancellous bone is introduced. First, the measurements and mathematical descriptions of the two-wave phenomenon are presented in Sect. 6.1. Here, a conventional mathematical method to understand the phenomenon and fundamental results of the experimental measurements are introduced. Next, in Sect. 6.2, the computational simulation methods using models representing real bone structures, the numerical or statistical separation techniques of the two waves, and machine learning techniques for deriving material information are discussed. Finally, in Sect. 6.3, the results and the current limitations of the clinical assessment with a device using the two-wave phenomenon are introduced.

ABSTRACT

INTRODUCTION: To investigate changes in refractive error in schoolchildren before and during the coronavirus disease 2019 (COVID-19) pandemic.

METHODS: This study included 2792 students, who underwent a 3-year follow-up from 2018 to 2020. All participants underwent yearly noncycloplegic refraction and ocular examinations. Time-related changes in sphere, cylinder, and spherical equivalent (SE) measurements in both genders were analyzed.

RESULTS: The myopic sphere (- 0.78 ± 1.83 vs. – 1.03 ± 1.91 D; P = 0.025) and SE (- 1.04 ± 1.90 vs. – 1.32 ± 1.99 D; P = 0.015) progressed significantly from 2018 to 2019. Female participants had a significantly greater change in SE than male participants (P < 0.05), and the low hyperopia, emmetropia, and mild myopia groups significantly deteriorated (P < 0.001) from 2018 to 2019. Significant differences in sphere change (- 0.21 ± 0.97 vs. – 0.36 ± 0.96 D; P < 0.001) and SE change (- 0.23 ± 0.99 vs. – 0.38 ± 0.98 D; P < 0.001) were noted between 2019-2018 and 2020-2019, respectively. The respective changes in cylinder were statistically similar (- 0.03 ± 0.53 vs. – 0.05 ± 0.62 D; P = 0.400).

CONCLUSIONS: The refractive status of schoolchildren showed an increasing myopic shift trend before and during the COVID-19 pandemic. The low hyperopia, emmetropia, and mild myopia groups were more sensitive to environmental changes during COVID-19 than before. The myopic shift was greater in female participants than male participants.

ABSTRACT

OBJECTIVE: To perform a systematic review to assess the effectiveness and safety of Reduning Injection versus neuraminidase inhibitors in treatment of influenza.

METHODS: The MEDLINE, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), Chinese Bio-medical Literature and Retrieval System (Sinomed), China National Knowledge Infrastructure Database (CNKI), China Science and Technology Journal Database (VIP), Wanfang Data Knowledge Service Platform and ClinicalTrails.gov were systematically searched from inception dates to May 2021 for randomized controlled trials (RCTs) exploring Reduning Injection alone or in combination with neuraminidase inhibitors in patients with influenza. Statistical analysis was performed using RevMan 5.4 and Stata 15.1. The qualities of the involved studies were assessed by the risk of bias according to the Cochrane handbook. The evidence quality of each outcome was evaluated by GRADEpro GDT.

RESULTS: Twelve trials with 1,460 patients were included. The included studies had a certain unclear or high risk of bias. Reduning Injection appeared to be more effective in shortening the fever clearance time (MD: -16.20 h, 95% CI: -19.40 to -12.99, 7 trials, 814 patients, I²=94%, very low certainty), fever alleviation time (MD: -4.09 h, 95% CI: -4.22 to -3.96, 3 trials, 366 patients, I²=0%, low certainty), cough alleviation time (MD: -21.34 h, 95% CI: -41.56 to -1.11, 2 trials, 228 patients, I²=89%, very low certainty), fatigue alleviation time (MD: -31.83 h, 95% CI: -36.88 to -26.77, 2 trials, 270 patients, I²=0%, low certainty), sore throat alleviation time (MD: -28.66 h, 95% CI: -32.23 to -25.10, 1 trial, 150 patients, low certainty), and improving the total effective rate (RR: 1.15, 95% CI: 1.06 to 1.25, 10 trials, 1,074 patients, I²=76%, very low certainty). Besides, Reduning Injection seemed generally safe.

CONCLUSIONS: This study provided low or very low evidence indicating Reduning Injection may be effective in the treatment of influenza and might be safe. Further rigorously designed studies are needed to confirm the effectiveness and safety of Reduning Injection and support it as a recommendation for influenza.

ABSTRACT

Although every glioma patient varies in tumor size, location, histological grade and molecular biomarkers, non-tumoral morphological abnormalities are commonly detected by a statistical comparison among patient groups, missing the information of individual morphological alterations. In this study, we introduced an individual-level structural abnormality detection method for glioma patients and proposed several abnormality indexes to depict individual atrophy patterns. Forty-five patients with a glioma in the frontal lobe and fifty-one age-matched healthy controls participated in the study. Individual structural abnormality maps (SAM) were generated using patients’ preoperative T1 images, by calculating the degree of deviation of voxel volume in each patient with the normative model built from healthy controls. Based on SAM, a series of individual abnormality indexes were computed, and their relationship with glioma characteristics was explored. The results demonstrated that glioma patients showed unique non-tumoral atrophy patterns with overlapping atrophy regions mainly located at hippocampus, parahippocampus, amygdala, insula, middle temporal gyrus and inferior temporal gyrus, which are closely related to the human cognitive functions. The abnormality indexes were associated with several molecular biomarkers including isocitrate dehydrogenase (IDH) mutation, 1p/19q co-deletion and telomerase reverse transcriptase (TERT) promoter mutation. Our study provides an effective way to access the individual-level non-tumoral structural abnormalities in glioma patients, which has the potential to significantly improve individualized precision medicine.

ABSTRACT

The COVID-19 pandemic has been monitored by applying different strategies, including SARS-CoV-2 detection with clinical testing or through wastewater-based epidemiology (WBE). We used the latter approach to follow SARS-CoV-2 dispersion in Tapachula city, located in Mexico’s tropical southern border region. Tapachula is a dynamic entry point for people seeking asylum in Mexico or traveling to the USA. Clinical testing facilities for SARS-CoV-2 monitoring are limited in the city. A total of eighty water samples were collected from urban and suburban rivers and sewage and a wastewater treatment plant over 4 months in Tapachula. We concentrated viral particles with a PEG-8000-based method, performed RNA extraction, and detected SARS-CoV-2 particles through RT-PCR. We considered the pepper mild mottle virus as a fecal water pollution biomarker and analytical control. SARS-CoV-2 viral loads (N1 and N2 markers) were quantified and correlated with official regional statistics of COVID-19 bed occupancy and confirmed cases (r > 91%). Our results concluded that WBE proved a valuable tool for tracing and tracking the COVID-19 pandemic in tropical countries with similar water temperatures (21-29 °C). Monitoring SARS-CoV-2 through urban and suburban river water sampling would be helpful in places lacking a wastewater treatment plant or water bodies with sewage discharges.

ABSTRACT

People who use crack cocaine (PWUCC) are a population severely impacted by a concentrated epidemic of HIV. Behavioral interventions to prevent and treat HIV among PWUCC have been implemented around the world including in low- and middle-income countries which have been disproportionately affected by HIV. However, few studies have validated and assessed psychometric properties of measures on PWUCC, especially in transnational populations. Our sample was comprised of 1324 PWUCC, Spanish mono-lingual speakers, residing in the metropolitan area of San Salvador, El Salvador. Exploratory factor analysis and subsequent confirmatory factor analysis using statistical softwares SPSS and Amos were conducted on three abbreviated and translated condom use attitude measures (i.e., Condom Use Attitudes Scale-Spanish Short Form, Condom Use Social Norm-Spanish Short Form [CUSN-SSF], Condom Use Self-Efficacy-Spanish Short Form). Convergent validity was examined by computing bivariate correlations between the scales and condom use and sexually transmitted disease diagnosis. Results indicated that a two-factor, 8-item correlated model for the CUAS-SSF scale had an excellent fit and adequate reliability (α = .76). The confirmatory factor analysis for the 5-item CUSN-SSF scale indicated a satisfactory fit with 3 of 6 fit indices indicating adequate fit. Analysis of the two-factor 5-item CUSE-SSF scale indicated satisfactory fit and adequate reliability (α = .84). There were significant correlations between all measures and with self-reported condom use. Results indicate that these brief measures are reliable and valid and can be utilized to assess the effectiveness of HIV risk reduction interventions among Spanish-speaking PWUCC.

ABSTRACT

PURPOSE: Transsphenoidal surgery (TSS) is the first-line treatment for patients with Cushing’s Disease (CD). Recurrence rates after a first TSS range between 3 and 22% within 3 years. Management of recurrent or persistent CD may include repeat TSS or stereotactic radiosurgery (SRS). We performed a meta-analysis to explore the overall efficacy of TSS and SRS for patients with CD after an initial surgical intervention.

METHODS: EMBASE, PubMed, SCOPUS, and Cochrane databases were searched from their dates-of-inception up to December 2021. Inclusion criteria were comprised of patients with an established diagnosis of CD who presented with persistent or biochemically recurrent disease after a first TSS for tumor resection and were treated with a second TSS or SRS.

RESULTS: Search criteria yielded 2,116 studies of which 37 articles from 15 countries were included for analysis. Mean age ranged between 29.9 and 47.9 years, and mean follow-up was 11-104 months. TSS was used in 669 (67.7%) patients, while SRS was used in 320 (32.4%) patients, and remission rates for CD were 59% (95%CI 0.49-0.68) and 74% (95%CI 0.54-0.88), respectively. There was no statistically significant difference in the remission rate between TSS and SRS (P = 0.15). The remission rate of patients with recurrent CD undergoing TSS was 53% (95%CI 0.32-0.73), and for persistent CD was 41% (95%CI 0.28-0.56) (P = 0.36).

CONCLUSION: Both TSS and SRS are possible approaches for the treatment of recurrent or persistent CD after a first TSS. Our data show that either TSS or SRS represent viable treatment options to achieve remission for this subset of patients.
