Published: November 2019

Abstract
Micromachining by cryo-focused ion beam (FIB) milling coupled to cryo-electron tomography (ET) enables visualization of macromolecules directly inside cells. Yet, spatial control of cell adhesion on electron microscopy (EM) grids remains a bottleneck in the specimen preparation pipeline. This protocol describes a contactless and mask-free photo-micropatterning of EM grids for site-specific deposition of extracellular matrix-related proteins. We achieved accurate and reproducible cell positioning, leading to optimized preparations for cryo-FIB milling. We tested HeLa and RPE1 cell lines on various grid types (gold or titanium mesh coated with SiO2, gold or carbon films). Briefly, grids were passivated with an anti-fouling agent, followed by controlled ablation of the passivation layer, and further functionalization with fibronectin. The micropatterning procedure takes ~3 h. Employing micropatterning to produce complex shapes generated a predictable intracellular organization, allowing direct correlation between cellular architecture and in-cell 3D-structural characterization of the underlying machinery at molecular resolution.

Abstract
Background: Although perioperative care during heart surgery has improved considerably, the rate of postoperative complications has remained stable. It has not been concluded how to better apply grip strength to clinical, postoperative complications. So our study aimed at researching the best way for using grip value for predicting early postoperative complications. Methods: A total of 212 patients with mean age 63.8±6.3 who underwent cardiac surgery participated in our study. We analyzed the ROC curve of grip strength, grip/weight and grip recovery with complications, found the best cutoff point. Logistic regression confirmed the association between grip strength grouping and complications. Results: We found that 36 patients had 30-day complications. EuroSCORE were 2.15±1.52 and 2.42±1.58 between normal and complication groups, respectively. The area under the receiver-operating characteristic curve (AUC) of grip recovery take the most area (0.837, p<0.001), and the cutoff point was 83.92%. In logistic regression, lower grip recovery has higher risk impact on 30-day complications for 25.68 times than normal group, after adjusted surgery-related factors. After regrouped characteristic information by grip recovery cutoff point , we found that percentage of the estimated 6 minute walk distance (41.5 vs 48.3, p=0.028) and hospitalization time (7.2 vs 6.1, p=0.042) had worse trends in lower recovery group. Conclusions: Poor grip recovery may be related to higher risk of postoperative complications within 30 days after discharge in middle-aged and older people independent of surgical risk. The results of this study provide a reference for the development of rehabilitation programs in the early postoperative recovery, and may also be a prognostic indicator for postoperative high-risk groups.

Published: November 2019

Abstract
Background: MicroRNAs (miRNA) in milk-derived exosomes may reflect pathophysiological changes caused by mastitis. This study profiled miRNAs in exosomes from both normal milk and mastitic milk infected by Staphylococcus aureus (S. aureus). The potential targets for differentially expressed (DE) miRNAs were predicted and the target genes for bta-miR-378 and bta-miR-185 were also validated.
Results: Total RNA from milk exosomes was collected from healthy cows (n=3, the control group) and S. aureus infected cows (n=6, the SA group). Two hundred ninety miRNAs (221 known and 69 novel ones) were identified. Among them, 22 known and 15 novel miRNAs were differentially expressed. Target genes of DE miRNAs were significantly enriched in intracellular protein transport, endoplasmic reticulum and identical protein binding. Two miRNAs (bta-miR-378 and bta-miR-185) with high read counts and log 2 fold changes (>3.5) were significantly higher in mastitic milk infected with S. aureus. One target gene (V AT1L) of bta-miR-378 and five target genes (DYRK1B , MLLT3 , HP1BP3 , NPR2 and PGM1) of bta-miR-185 were validated.
Conclusion: DE miRNAs in exosomes from normal and S. aureus infected milk were identified. The predicted targets for two DE miRNAs (bta-miR-378 and bta-miR-185) were further validated. The linkage between the validated target genes and diseases suggested that we should pay particular attention to exosome miRNAs from mastitic milk in terms of milk safety.

Published: November 2019

Abstract
Background: glomerular filtration rate (GFR) is a valid indicator for kidney function. Different factors can affect GFR. The purpose of this study is to assess direct and indirect effects of GFR-related factors using structural equation modeling.Patients and methods:We analyzed data from baseline phase of Ravansar Non-Communicable Disease cohort study. Data on socio-behavioral, nutritional, cardiovascular, and metabolic risk factors were entered in a conceptual model in order to test direct and indirect effects of factors related to GFR,separately in male and female, using the structural equation modeling.Results: Of 8927 individuals participated in this study, 4212 subjects were male (47.20%) and 4715 subjects were female (52.80%). The obtained mean and standard deviation of GFR was 76.05 (±14.31) per 1.73 . GFR for 0.2%, 11.3%, 73.0% and 15.50% of people were <30, , and , respectively. Hypertension and aging in both gender and atherogenic factor in male directly, and in female directly and indirectly had a lower effect on GFR. Blood urea nitrogen and smoking in male and female, directly or indirectly through other variables, were associated with a lower GFR. In female, diabetes had a lower direct and indirect effect on GFR. Obesity in female was directly associated with uper and indirectly associated with lower GFR.Conclusion: According to our results, aging, hypertension, diabetes, obesity and high lipid profile, and BUN had a decreasing direct and indirect effects on GFR. Although low GFR might have different reasons and it is not a consistent sign of CKD, our findings, are in line with other reports, provide more detailed informations about important risk factors of low GFR. Public awareness about such factors can improve public practice of positive health behaviours.

Published: November 2019

Abstract
Aim: To study whether early intervention services (EI) and a follow-up program (FU) influence outcomes of children with cerebral palsy (CP) in Moldova.
Methods: Records from 351 children with CP in Moldova born during 2009 and 2010 were retrieved from hospital and orphanage archives between 1 July 2016 and 30 September 2017. We investigated the proportion enrolled in EI and FU at the Early Intervention Centre Voinicel and at the Institute of Mother and Child in 2009-2012. Logistic regression analyses were applied to calculate crude and adjusted odds ratios (OR) with 95% confidence intervals (CI) for outcomes in children enrolled and not enrolled.
Results: Among all children with CP, 166 (47%) were enrolled in EI and FU. Of the 51 children born extremely preterm (gestational age ≤31 weeks), 46 (90%) were enrolled, compared to 97 (39%) of the 250 children born at term. Among 110 non-walking children with CP, 82 (74%) were enrolled into EI and FU, compared to 84 (35%) of 241 able to walk.
There was no difference in outcomes of cognition, communication, vision and hearing impairments between those enrolled or not enrolled in EI and FU. However, the subgroup analyses showed that the risk of contractures was five times higher among those not enrolled, regardless of GMFCS level (OR = 5.474, 95% CI 3.306–9.063, p <0.000).
Conclusion: In Moldova, EI and FU seem to be offered mostly to extremely preterm and non-walking children with CP. The results indicate a decreased risk for contractures in these children.

Abstract
Objectives: Medication management capacity of a patient on ambulatory care is direct related to adherence. To our knowledge data on medication management capacity for ambulatory care patients exiting outpatient pharmacy outlets in Tanzania are scarce. This study aimed to determine the level of medication management capacity among patients on ambulatory care exiting Muhimbili National Hospital outpatient pharmacy outlet. Results: A total of 424 patients on ambulatory care participated in the study. Three hundred eighty seven (91.3%) out of 424 interview questionnaires had complete data and qualified for data analysis. Majority (62.3%) out of 387 study participants had poor medication management capacity; 65.3% out of 387 patients were unable to correctly read the prescription and match the drugs they are carrying. More than half (57.4%) out of 387 participants were unable to correctly take the dose, 73.9% out of 387 were unable to correctly tell the dosing frequency and duration. Only 10.6% out 155 patients with prescription containing drugs with warning or precaution or contraindication or potential side effects were aware.

Abstract
Background: Current newborn screening (NBS) in China is mainly aimed at detecting biochemical levels of metabolites in the blood, which may generate false positive/negative results. To explore whether next-generation sequencing (NGS) for dried blood spots can increase the detecting rate of genetic disorders, we carried out a pilot study using NGS in 1,173 newborns who had been tested by traditional NBS. With a focus on inherited metabolic diseases (IMDs), our team investigated the current frequencies of genes related to common inherited metabolic diseases in this cohort.
Methods: We designed an NGS panel of 573 genes related to severe diseases and performed NBS in 1,173 individuals who had been screened by tandem mass spectrometry (MS/MS) as well as for phenylalanine (Phe), thyroid-stimulating hormone (TSH), 17-α-hydroxyprogesterone (17-OHP), and glucose-6-phosphate dehydrogenase (G6PD) abnormalities in a traditional biochemical NBS conducted in September 2016. We compared the biochemical results to the genetic variants and investigated the carrier frequencies of 77 genes related to disorders by MS/MS in these newborns.Results: The biochemical results showed that four newborns (all male) were positive for G6PD by enzymatic assay, while the other biochemical findings including MS/MS, Phe, TSH and 17-OHP were negative. Genetic analysis results revealed that all the four newborns with positive G6PD values harbored hemizygous G6PD mutations. The NGS results also revealed an individual (ID 84123) carrying two SLC22A5 mutations (c.760C>T/p.R254* and c.1400C>G/p.S467C) common in Chinese patients with carnitine deficiency, which were later verified to be in trans, who was biochemically negative in 2016. The MS/MS results in 2019 showed free carnitine deficiency, consistent with the genetic analysis findings. The top five genes with the highest carrier frequencies in these newborns were PAH (1.77%), ETFDH (1.24%), MMACHC (1.15%), SLC25A13 (0.98%), and GCDH (0.80%).
Conclusions: Our study provided data combing biochemical results with genetic variants in 1,173 newborns and confirmed a primary carnitine deficiency patient with false-negative biochemical results. This is also the first study to report the carrier frequencies of 77 IMD-causing genes in China.

Abstract
Objective The aim of this study was to determine the prevalence of intestinal parasitic infections and associated factors among school children in Sebeya primary school, Northern Ethiopia, 2017.Results The prevalence of intestinal parasites in school age children was (29.9%). E.histolytica/dispar 62 (49.21%), G.lamblia 28 (22.22%), and A. lumbricoides 23 (18.25%) were the most prevalent parasitic organisms identified. Unclean finger nail (AOR= 1.72), defecating in the open field (AOR=2.82), and being barefooted (AOR=1.72) were the determinant factors for intestinal parasitic infections. Frequently washing hands reduced the chance of infections by 68%. Furthermore, children in grade 1-4 and 5-6 had higher odds developing the infections than those in grade 7-8 (AOR=8.21 and AOR=2.50, respectively).

Published: November 2019

Abstract
Background:

Incisional hernias are among the most frequent complications following abdominal surgery and cause substantial morbidity, impaired health-related quality of life and costs. Despite improvements in abdominal wall closure techniques the risk for developing an incisional hernia is reported to be between 10-30% following midline laparotomies. There have been two recent innovations with promising results to reduce hernia risks, namely the small stitches technique and the placement of a prophylactic mesh. So far, these two techniques have not been evaluated in combination.

Methods:

The HULC trial is a multicentre randomized controlled, observer and patient blinded surgical effectiveness trial with two parallel study groups. A total of 812 patients scheduled for elective abdominal surgery via a midline laparotomy will be randomized in 12 centres after informed consent. Patients will be randomly assigned to the control group receiving closure of the midline incision with a slowly absorbable monofilament suture in small stitches technique or to the intervention group that will receive a small stitches closure followed by augmentation with a light-weight polypropylen mesh in onlay technique. The primary endpoint will be the occurrence of incisional hernias as defined by the European Hernia Society within 24 months after surgery. Further perioperative parameters, as well as patient-reported outcomes, will be analysed as secondary outcomes.

Discussion:

The HULC trial will address the yet unanswered question whether a combination of small stitched fascial closure and onlay mesh augmentation after elective midline laparotomies reduces the risk of incisional hernias. The HULC trial marks the logical and innovative next step in the development of a safe abdominal closure technique.

Abstract
Background: Irritable bowel syndrome (IBS) is one of the most acommon functional gastrointestinal disorders characterized by recurrent abdominal pain associated with defecation or a change in bowel habits. Leading to significant negative effect on patients’ quality of life and huge financial burden to health system, the management of IBS is a great challenge. Probiotics are considered as an effective therapy, however, in a lack of high-quality evidence of efficacy, no specific strain- and dose-probiotics were recommended in clinical guidelines. This study aims to evaluate the efficacy of the bifidobacterium quadruple viable tablet in the treatment of IBS-D.
Methods/design: A multicenter randomized controlled trial will be performed in fourteen hospitals. A total of three hundred patients fulfill the eligible criteria will be stratified divided into an experimental group and a control group randomly in a ratio of 1:1. The experimental group is treated with the bifidobacterium quadruple viable tablet while the control group is treated with placebo. All the patients will receive a 4-week treatment and a 2-week follow-up. The primary outcome is the effectiveness in improving abdominal pain and stool consistency, the secondary outcome include evaluation of overall symptom relief, frequency of defecation, bloating, urgency of defecation, remedial medication, score of IBS-QOL and changes of microbiota and metabonomics. Physical examination, vital signs, laboratory tests, adverse events and concomitant medication will be taken into account for intervention safety assessment during the trial.
Discussion: This multicenter randomized controlled trial may provide high-quality evidence on the efficacy of the bifidobacterium quadruple viable tablet for IBS-D on both physical and mental dimensions in China. To fill the gap of previous probiotics intervention studies, in addition, this study will also present safety assessment which will be a significant emphasis.
Perceptions about preconception care among health care providers in Ibadan, southwest Nigeria - A qualitative study
Authors: Ojifinni Oludoyinmola Omobolade , Ibisomi Latifat 
Published: November 2019

Abstract
Background:
Preconception care (PCC) is a recognised strategy for optimising maternal health and improving maternal and neonatal outcomes. Research has shown that PCC services are minimally available and yet to be fully integrated into maternal health services in Nigeria. This study explored the perceptions about PCC services among health care providers in Ibadan, Nigeria.
Methods:
This was a case study research among 26 health care providers – 16 specialist physicians and nine nurses covering 10 specialties: Obstetrics/Gynaecology, Cardiology, Endocrinology among others at the primary, secondary and tertiary health care levels. In-depth interviews were digitally recorded, transcribed verbatim and analysed on MAXQDA using thematic analysis.
Results:
Six main themes were identified from the data – scope of PCC, people who require PCC, where PCC services can be provided, acceptability of PCC services, relevance of PCC to different specialties including gynaecologists, cardiologists, nephrologists, psychiatrists and possible benefits of PCC. PCC was viewed as care for women, men and couples before pregnancy to optimise health status and ensure positive pregnancy outcomes. Almost all participants stated that PCC services should be offered at all three levels of health care with referral when needed from the lower to higher levels. The prevailing opinion on the circumstances when PCC is required was that although all people of reproductive age would benefit, those who had medical problems such as hypertension, sickle cell disease, diabetes and infertility would benefit more. Participants opined that delayed health care seeking observed in the community may influence acceptability of PCC especially for people without known pre-existing conditions. All specialist physicians identified the relevance of PCC to their practice and identified potential benefits of PCC. The potential benefits outlined included opportunity to plan and prepare for pregnancy to ensure positive pregnancy outcomes.
Conclusion:
Preconception care is perceived as being more important for promoting positive pregnancy outcomes in people with known medical problems and is relevant to different specialities of medical practice. Provision of the service will however require establishment of guidelines and its uptake will depend on acceptability to people with known medical problems who will benefit from the service.

Abstract
Background: Soybean (Glycine max) is an economically important oil and protein crop. Plant height is a key trait that significantly impacts the yield of soybean; however, research on the molecular mechanisms associated with soybean plant height is lacking. The CRISPR (clustered regularly interspaced short palindromic repeat)/Cas9 (CRISPR-associated system 9) system is a recently developed technology for gene editing that has been utilized to edit the genomes of crop plants.
Results: Here, we designed four gRNAs to mutate four LATE ELONGATED HYPOCOTYL (LHY) genes in soybean. In order to test whether the gRNAs could perform properly in transgenic soybean plants, we first tested the CRISPR construct in transgenic soybean hairy roots using Agrobacterium rhizogenes strain K599. Once confirmed, we performed stable soybean transformation and obtained 19 independent transgenic soybean plants. Subsequently, we obtained one T1 transgene-free homozygous quadruple mutant of GmLHY by self-crossing. The phenotypes of the T2-generation transgene-free quadruple mutant plants were observed, and the results showed that the quadruple mutant of GmLHY displayed reduced plant height and shortened internodes. The levels of endogenous gibberellic acid (GA3) in Gmlhy1a1b2a2b was lower than in the wild type (WT), and the shortened internode phenotype could be rescued by treatment with exogenous GA3. In addition, the relative expression levels of GA metabolic pathway genes in the quadruple mutant of GmLHY were significantly decreased in comparison to the WT. These results suggest that GmLHY encodes an MYB transcription factor that affects plant height through mediating the GA pathway in soybean. We also developed genetic markers for identifying mutants for application in breeding studies.
Conclusions: Our results indicate that CRISPR/Cas9-mediated targeted mutagenesis of four GmLHY genes reduces soybean plant height and shortens internodes from 20 to 35 days after emergence (DAE). These findings provide insight into the mechanisms underlying plant height regulatory networks in soybean.
