Published: June 2022

Abstract
Background
Okra (Abelmoschus esculentus L. Moench) is an economically important crop and is known for its slimy juice, which has significant scientific research value. The A. esculentus chloroplast genome has been reported; however, the sequence of its mitochondrial genome is still lacking.

Results
We sequenced the plastid and mitochondrial genomes of okra based on Illumina short reads and Nanopore long reads and conducted a comparative study between the two organelle genomes. The plastid genome of okra is highly structurally conserved, but the mitochondrial genome of okra has been confirmed to have abundant subgenomic configurations. The assembly results showed that okra’s mitochondrial genome existed mainly in the form of two independent molecules, which could be divided into four independent molecules through two pairs of long repeats. In addition, we found that four pairs of short repeats could mediate the integration of the two independent molecules into one complete molecule at a low frequency. Subsequently, we also found extensive sequence transfer between the two organelles of okra, where three plastid-derived genes (psaA, rps7 and psbJ) remained intact in the mitochondrial genome. Furthermore, psbJ, psbF, psbE and psbL were integrated into the mitochondrial genome as a conserved gene cluster and underwent pseudogenization as nonfunctional genes. Only psbJ retained a relatively complete sequence, but its expression was not detected in the transcriptome data, and we speculate that it is still nonfunctional. Finally, we characterized the RNA editing events of protein-coding genes located in the organelle genomes of okra.

Conclusions
In the current study, our results not only provide high-quality organelle genomes for okra but also advance our understanding of the gene dialogue between organelle genomes and provide information to breed okra cultivars efficiently.

Abstract
Objective
The primary percutaneous coronary intervention (PPCI) is the preferred reperfusion strategy for ST-segment elevation myocardial infarction (STEMI). The pharmacoinvasive strategy (PIs) is a reasonable alternative when prompt PPCI is not possible, especially in resource-limited regions. We aimed to compare PPCI versus PIs outcomes in Peru.

Methods
This was a retrospective cohort study based on the second Peruvian Registry of STEMI (PERSTEMI II). We compared the characteristics, in-hospital outcomes and 30-day mortality of patients undergoing PPCI during the first 12 h and those receiving a PIs. A propensity score-matched analysis was conducted to compare the effects of each treatment strategy on clinical outcomes.

Results
PIs patients were younger than PPCI patients, had a shorter first medical contact time, first medical contact to reperfusion time, and total ischemic time until reperfusion. Successful PCI was more frequent in the PIs group (84.4% vs. 71.1%, p = 0.035). There were no differences between PIs and PPCI in terms of total in-hospital mortality (5.2% vs. 6.6%, p = 0.703), cardiovascular mortality (4.2% vs. 5.3%, p = 0.735), cardiogenic shock (8.3% vs. 13.2%, p = 0.326), heart failure (19.8% vs. 30.3%, p = 0.112), or major bleeding (0% vs. 2.6%, p = 0.194). In the propensity score-matched analysis, the rates of cardiovascular mortality, postinfarction heart failure and successful reperfusion were similar.

Conclusions
In this real-world study, no differences were found in the in-hospital outcomes between patients with STEMI who received PIs or PPCI.
Transcatheter arterial chemoembolization alone versus combined with microwave ablation for recurrent small hepatocellular carcinoma after resection: a retrospective comparative study
Authors: Ji Jie , Yang Wei , Shi Hai-Bin , Liu Sheng , Zhou Wei-Zhong 
Published: June 2022

Abstract
Purpose
To compare the efficacy and safety of transcatheter arterial chemoembolization combined with microwave ablation (TACE–MWA) versus TACE alone for the treatment of recurrent small hepatocellular carcinoma (sHCC) after resection.

Materials and methods
From June 2015 to January 2020, a total of 45 patients with recurrent sHCC (size ≤ 3 cm) treated by TACE–MWA or TACE were included in this study. The radiological response at 1-, 3-, 6-month after initial treatment [modified Response Evaluation Criteria in Solid Tumors (mRECIST)], progression-free survival (PFS), overall survival (OS), and complications were evaluated.

Results
The TACE–MWA group showed better 1-, 3-, 6-month tumor response rates than TACE group. The corresponding 1-, 3-, and 5-year PFS rates were 76.5%, 70.6%, and 70.6% for the TACE–MWA group, and 56.1%, 15.0%, and 15.0% for the TACE group (P = 0.003). The 1-, 3-, and 5-year OS rates were 100.0%, 82.1%, and 61.5% for the TACE–MWA group, and 89.0%, 58.1%, and 50.8% for the TACE group (P = 0.389), respectively. Moreover, no major complications related to treatment were observed in either of the groups. Compared with the TACE group, the TACE–MWA group had a significantly lower number of re-TACE sessions (P = 0.003).

Conclusions
Although TACE alone provides equivalent effectiveness for recurrent sHCC in terms of OS rates, TACE–MWA had better 1-, 3-, 6-month tumor response rates and may prolong tumor PFS time.

Published: June 2022

Abstract
Background
Physical activity and a healthy diet are important in helping to maintain mobility with aging. This umbrella review aims to identify group-based physical activity and/or nutrition interventions for community-dwelling older adults that improve mobility-related outcomes.

Methods
Five electronic databases (MEDLINE, Embase, CINAHL, Cochrane CENTRAL, Sociological Abstracts) were searched from inception to December 2021. Eligibility criteria included systematic reviews exploring the effectiveness of physical activity or structured exercise, alone or combined with nutrition interventions on mobility-related outcomes (aerobic capacity, physical function, balance, falls/safety, muscle strength, health-related quality of life/wellbeing). Interventions must have been delivered in a group setting to community-dwelling older adults aged 55+. Two reviewers independently performed eligibility screening, critical appraisal (using AMSTAR 2) and data extraction. The GRADE approach was used to reflect the certainty of evidence based on the size of the effect within each mobility-related outcome category. Older adult/provider research partners informed data synthesis and results presentation.

Results
In total, 62 systematic reviews (1 high, 21 moderate, 40 low/critically low quality) were identified; 53 included physical activity only, and nine included both physical activity and nutritional supplements. No reviews included nutrition interventions alone. Combined aerobic/resistance, general physical activity, and mind-body exercise all improved physical function and balance (moderate-high certainty). Aerobic/resistance training improved aerobic capacity (high certainty). Resistance training and general physical activity improved muscle strength (moderate certainty). Aerobic/resistance training and general physical activity are likely to reduce falls among older adults (moderate certainty). There was no evidence of benefit for nutritional supplementation with physical activity.

Conclusions
Group-based physical activity interventions that combine aerobic and resistance, general PA and mind-body exercise can improve measures of mobility in community-dwelling older adults. We found no reviews focused on nutrition only, highlighting a gap in the literature.

Authors: Kerr C. , Kelleher M. , Coughlan S. , Crowley B. , O’Reilly E. J. , Bergin C. 
Published: June 2022

Abstract
Background
HIV infection is associated with an increased risk of morbidity and mortality from vaccine preventable infections. This research describes, in the context of changing patient demographics, the seroprevalence of vaccine preventable viral infections among attendees of the largest centre for HIV positive patients in Ireland.

Methods
Baseline serum IgG results for measles, mumps, rubella, varicella zoster virus (VZV) & hepatitis A, as well as hepatitis B sAg, cAb and sAb results, were retrieved for 2534 clinic attendees attending in 2018. Results were available for between 990 and 2363 attendees (39–93%), depending on the test, and were compared with 2013 clinic data.

Results
There was a 35% increase in attendees in 2018 when compared to 2013. The largest increase was in attendees of South American origin. In 2018, males accounted for 73% of the entire cohort and the HIV acquisition risk for 48% of attendees was MSM. 47% of attendees were originally from Ireland. Among those tested, 33% were susceptible to at least one component of the MMR vaccine. 5% were VZV non-immune (significantly associated with younger age and the acquisition risk status of injection drug use). 21% were hepatitis A non-immune (significantly associated with younger age and being of European or South American origin). 32% were hepatitis B cAb seropositive (significantly associated with older age, injection drug use status and being originally from Africa). 3% demonstrated hepatitis B sAg positivity. 64% had hepatitis B sAb ≥ 10mIU.

Conclusion
In a cohort of attendees to an HIV clinic in a large urban setting, the susceptibility to several common vaccine preventable viral infections, in particular MMR and hepatitis A and B, was high. These results highlight the importance of proactive screening and immunisation to help protect this high risk patient group against vaccine preventable diseases.
Plasma C4 level was associated with mortality, cardiovascular and cerebrovascular complications in hemodialysis patients
Authors: Xing Zheyu , Wang Yaqin , Gong Kunjing , Chen Yuqing 
Published: June 2022

Abstract
Background
Patients on maintenance hemodialysis (HD) exhibit a high risk of death, cardiovascular and cerebrovascular diseases (CCDs). Previous studies indicated complement activation associated with the increased risk of cardiovascular diseases in HD patients. This study aimed to explore whether the critical complement factors were associated with the adverse outcomes in HD patients.

Methods
A total of 108 HD patients were included and followed up for 52 months. The baseline clinical characteristics and plasma C3c, C1q, CFH, CFB, C4, MAC, C5a, C3a and MBL were measured. The three endpoints were death, cardiovascular and cerebrovascular events (CCEs) and the composition of them. Univariate and multivariate Cox regression identified factors associated with the three endpoints respectively. X-tile analyses determined the optimal cut-off values for high risks. Restricted cubic spline plots illustrated the dose–response relationships. Correlations between the complement factors and risk factors for CCDs were analyzed.

Results
Baseline plasma C4 was finally selected by univariate and multivariate Cox regression analyses for three endpoints, including all-cause mortality, CCEs and the composition of them. When baseline plasma C4 exceeded 0.47 (P = 0.001) or 0.44 (P = 0.018) g/L respectively, the risks for death or achieving the composite endpoint enhanced significantly. The relationships of C4 and HR for the three endpoints showed a positive linear trend. Plasma C4 had prominent correlations with blood TG (r = 0.62, P < 0.001) and HDL (r = -0.38, P < 0.001).

Conclusions
A higher baseline plasma C4 level was significantly associated with the future incidence of decease, CCEs and either of them. Plasma C4 level correlated with blood TG and HDL.
Prepregnancy body mass index, gestational weight gain, and maternal prepartum inflammation in normal pregnancies: findings from a Chinese cohort
Authors: Li Kuanrong , Yang Chuanzi , Fan Jiaying , Li Xiaojun , Gu Chongjuan , Liu Huishu 
Published: June 2022

Abstract
Background
Obesity has been linked to systemic inflammation in population studies.

Objective
To examine the associations of prepregnancy body mass index (pBMI) and total gestational weight gain (tGWG) with maternal prepartum low-grade inflammation (LGI) and clinically significant inflammation (CSI) defined by serum C-reactive protein (CRP) concentration.

Methods
Five thousand four hundred seventy-six Chinese women with uncomplicated pregnancies and recorded data on pBMI and prepartum body weight were included in this study. Blood samples were drawn before delivery for high-sensitivity CRP assay. Inadequate, optimal, and excessive tGWG were defined using the Institute of Medicine's recommendation. Multivariable Poisson regressions were used to estimate relative risks (RRs) for having prepartum LGI and CSI (defined as CRP concentration 3–10 and > 10 mg/L, respectively) across pBMI and tGWG categories.

Results
The mean pBMI, mean tGWG, and median maternal prepartum CRP concentration were 20.4 kg/m2, 13.9 kg, and 3.3 mg/L, respectively. The prevalence of prepartum CSI and LGI was 7.2% and 47.8%. The adjusted RRs (95% confidence interval) of CSI for normal (18.5–24.9 kg/m2) and high (≥ 25 kg/m2) vs. low pBMI (< 18.5 kg/m2) were 1.35 (1.05–1.74) and 2.28 (1.53–3.39), respectively. The respective adjusted RRs of LGI were 1.19 (1.11–1.28) and 1.59 (1.42–1.77). The adjusted RRs for excessive vs. optimal tGWG was 1.18 (0.94–1.48) for CSI and 1.14 (1.07–1.21) for LGI.

Conclusions
Prepregnancy overweight/obesity and excessive tGWG increase the risk of maternal prepartum systemic inflammation, which further highlights the importance of weight management before and during pregnancy.
Preeclampsia risk prediction model for Chinese pregnant women (ChiPERM): research protocol for a randomized stepped-wedge cluster trial
Authors: Zhou Qiongjie , Xu Jinghui , Xiong Yu , Li Xiaotian 
Published: June 2022

Abstract
Background
Despite international clinical guideline recommendations, implementation of Bayes-theorem based preeclampsia risk prediction model in first trimester among Chinese women is limited. The aim of this study is to examine the effectiveness of this risk predictive strategy in reducing the risk of preeclampsia.

Methods
The study will be a randomized, stepped-wedge controlled trial conducted in eighteen hospitals in China. Stepped implementation of Bayes-theorem based risk prediction model will be delivered to hospitals in a random order to support the introduction of this prediction model of preeclampsia. A staged process will be undertaken to develop the risk prediction strategies, which comprise of: combined risk evaluation by maternal risk factors, medium arterial pressure, uterine artery pulse index and placenta growth factor during 11–13+6 gestational weeks, monthly follow up (including blood pressure, newly onset complications, adherence to aspirin). Repeated cross-sectional outcome data will be gathered weekly across all hospitals for the study duration. The primary outcome measures are the incidence of preeclampsia within 42 days postpartum. Data on resources expended during intervention development and implementation will be collected. The incidence of pregnancy related complications will be measured as secondary outcomes.

Discussion
This will be the first randomized controlled trial to evaluate the effectiveness of the Bayes-theorem based preeclampsia risk prediction strategies in first trimester by competing risk model validation. If positive changes in clinical practice are found, this evidence will support health service adoption of this risk prediction model to reduce the risk of preeclampsia among Chinese pregnant women.

Switching to ziv-aflibercept in resistant diabetic macular edema non responsive to ranibizumab injection
Authors: Nawar Amin E. , Wasfy Tamer , Shafik Heba M. 
Published: June 2022

Abstract
Background
Diabetic macular edema (DME) is a leading cause of visual loss in diabetic patients and is managed using multiple anti-vascular endothelial growth factor (VEGF) agents such as bevacizumab, ranibizumab and aflibercept. The present study evaluates effectiveness of intravitreal injection of ziv-aflibercept in resistant diabetic macular edema.

Methods
This is a prospective interventional study that was carried out on 59 eyes of 40 diabetic patients with diabetic macular edema resistant to three prior consecutive ranibizumab injections. On all patients, thorough ophthalmic evaluation including optical coherence tomography was performed. In patients with persistent intraretinal or subretinal fluid, ziv- aflibercept 1.25 mg (0.05 ml) was administered by intravitreal injection monthly during the 6 month study period from June to December 2019.

Results
The central macular thickness (CMT) decreased significantly from 395.08 ± 129.9 um at baseline to 282.39 ± 95.278, 245.36 ± 79.861 and 201.17 ± 54.042 after 1, 3 and 6 months of treatment respectively (p < 0.001). Best corrected visual acuity (BCVA) in log MAR units was significantly improved from 0.95 ± 0.21 to 0.51 ± 0.23 after 6 months (p = 0.001). After treatment, negative correlations were detected between age, number of injections, duration of DM and level of glycated hemoglobin (HbA1c) and variation of both CMT and BCVA. The only significant predictor for low final CMT after 6 months of injection was the CMT after 3 months of injection (p = 0.001).

Conclusion
Ziv-aflibercept is a highly effective and safe drug in cases of DME resistant to previous ranibizumab injections especially in low-income countries.

Branch retina vein occlusion combined with angle-closure glaucoma is associated with a mutation in BEST1: a case report
Authors: Yin Xue , Cai Qinhua 
Published: June 2022

Abstract
Background
It is rare for a patient to be diagnosed with branch retina vein occlusion (BRVO), angle-closure glaucoma (ACG) and autosomal recessive bestrophinopathy (ARB). ARB is strongly associated with ACG. Although glaucoma is a significant risk factor for RVO, there is a plausible relationship between ACG and BRVO. To discuss correlation of these diseases is necessary.

Case presentation
The genetic testing and medical treatment of a patient with ocular fundus diseases and ACG were recorded. We present a 47-year-old male patient with BRVO who was diagnosed with angle-closure glaucoma and a homozygous mutation of c.140G > A (p.R47H) in BEST1. Intravitreal ranibizumab was administered in combination with three antiglaucomatous eyedrops to lower intraocular pressure (IOP) in the right eye. One month later, BCVA improved to 0.3. IOP was controlled at 13 mmHg.

Conclusions
ACG was likely combined to ARB, while there’s a plausible relationship between ACG and BRVO.

AbstractBackgroundChild-oriented goal-setting in pediatric rehabilitation may improve child motivation, engagement in therapy, child outcomes related to therapy, and service delivery efficiency. The primary objective of this trial is to determine the effectiveness of a principles-driven, child-focused approach to goal-setting, Enhancing Child Engagement in Goal-Setting (ENGAGE), on pediatric rehabilitation outcomes compared to usual practice. The three secondary objectives are to 1) compare costs and secondary outcomes of the ENGAGE approach to usual practice, 2) determine the influence of child, parent and therapist characteristics on child engagement in therapy and rehabilitation outcomes, and 3) identify barriers and facilitators to the implementation of ENGAGE.MethodsThis research protocol describes a pragmatic, multi-site, cluster, effectiveness-implementation (hybrid type 1 design) randomized controlled trial. Therapists (n = 12 clusters of two therapists) at participating sites (n = 6) will be randomized to 1) the ENGAGE intervention group, or 2) usual care (control) using a computer-generated, permuted-block randomization sequence with site as a stratification variable designed by a statistician (RR). Each therapist will recruit four children 5–12 years old with neurodevelopmental conditions (n = 96), who will receive ENGAGE or usual care, according to therapist group allocation. ENGAGE therapists will be trained to use a 'toolbox' of evidence-driven, theory-informed principles to optimize child and parent motivation, engagement in the goal-setting process, and performance feedback strategies. Outcomes include goal performance (primary outcome), engagement in therapy, functional abilities, participation, and parent and child quality of life. Qualitative interviews with children, parents, ENGAGE therapists, and managers will explore challenges to implementation and potential mitigation strategies. Mixed effects multiple linear regression models will be developed for each outcome to assess group differences adjusted for clustering. A cost-effectiveness analysis will combine cost and a measure of effectiveness into an incremental cost-effectiveness ratio. Qualitative data on implementation will be analyzed inductively (thematic analysis) and deductively using established implementation science frameworks.DiscussionThis study will evaluate the effects of collaborative goal-setting in pediatric rehabilitation and inform effective implementation of child-focused goal-setting practices.Trial RegistrationNCT05017363(registered August 23, 2021 on ClinicalTrials.gov).
Incontinentia pigmenti inherited from a father with a low level atypical IKBKG deletion mosaicism: a case report
Authors: Kawai Miki , Sugimoto Atsuya , Ishihara Yasunori , Kato Takema , Kurahashi Hiroki 
Published: June 2022

Abstract
Background
Incontinentia pigmenti (IP) is an X-liked dominant genodermatosis caused by mutations of the IKBKG/NEMO gene. IP is mostly lethal in males in utero, and only very rare male cases with a somatic mosaic mutation or a 47,XXY karyotype have been reported.

Case presentation
We here report a case of an IKBKG gene deletion in a female infant presenting with a few blisters and erythema in her upper arms at birth. MLPA analysis revealed a rare 94 kb deletion in this patient, encompassing the IKBKG gene and IKBKGP pseudogene. PCR analysis indicated the presence of Alu elements at both ends of the deletion, suggesting non-allelic homologous recombination as an underlying mechanism. Notably, a low-level mosaic deletion was identified in her father’s peripheral blood leukocytes by PCR, suggesting a rare father-to-daughter transmission of IP.

Conclusion
In family studies for an apparently sporadic IP case, parental analysis that includes the father is recommended due to the possibility of male mosaicism.
