Abstract
Background
Recent advances in prenatal screening and diagnosis have resulted in an increasing number of women receiving a diagnosis of fetal anomalies. In this study, we aimed to clarify the hopes for childbirth and parenting of women diagnosed with fetal anomalies and to suggest a family-centered care tailored for this situation in perinatal settings.

Methods
A descriptive qualitative study was performed. We recruited women diagnosed with fetal anomalies who were over 22 years old, beyond 22 weeks of gestation, and had scheduled pregnancy and delivery management at a tertiary perinatal medical center specializing in neonatal and pediatric care in a metropolitan area of Japan from April 2019 to December 2019. Women who were willing to participate received support from a midwife to create birth plans. Data were collected from the documented birth plans submitted by 24 women and analyzed using content analysis.

Results
We identified three themes of women’s hopes based on the descriptions of the submitted birth plans: (1) Hopes as women who are expecting childbirth, (2) Hopes as mothers of a baby, (3) Hopes of being involved in the family needs. Several distinctive hopes were clarified in the context of the women’s challenging situations. In describing their hopes, the women were neither overoptimistic or overstated their actual situations, nor caused embarrassment to the healthcare providers. The importance of supporting their involvement in baby matters in the way each family wants also emerged. However, several barriers to fulfilling the women’s hopes were identified including the babies’ conditions and hospital regulations against family visits or presence.

Conclusion
All three themes identified in the study provide important insights for analyzing more deeply ways of implementing a family-centered care for women diagnosed with fetal anomalies in perinatal settings. To improve women’s engagement in decision-making as a team member, women’s hopes should be treated with dignity and respect, and included in the perinatal care of women with abnormal fetuses. Further research is needed to improve the inclusion of women’s hopes in their care in clinical settings.

Published: October 2022

Abstract
Objective
To evaluate the effect of gentamicin in surgical perfusion solution on endophthalmitis incidence after cataract surgery.

Methods
A retrospective analysis of endophthalmitis incidence was conducted in two groups of patients who underwent cataract surgery, with (Group B) or without gentamicin (Group A) in the surgical perfusion solution. Endophthalmitis incidence, the isolated pathogenic bacteria strains and their antibiotic sensitivity, and the drug-resistant genotype of the pathogens were examined.

Results
The incidence of endophthalmitis in patients of group A was 0.8‰. Thirteen pathogenic bacterial strains were isolated from the patient samples in group A, including 8 strains of Staphylococcus epidermidis, 1 Staphylococcus aureus, 1 Streptococcus pneumoniae, 1 Streptococcus bovis, 1 Enterococcus faecium and 1 Morganella sp. The incidence of endophthalmitis in group B patients was 0.2‰, which was significantly lower than that in group A (P<0.05). Five strains of pathogenic bacteria were successfully isolated, including 2 strains of Enterococcus faecium, 1 Enterococcus faecalis, 1 Staphylococcus epidermidis and 1 Staphylococcus aureus. There was no significant difference in the proportion of Staphylococcus strains in all isolated bacteria between the two groups (P > 0.05). However, the proportion of Enterococci isolated in group B samples was higher than that in group A (P < 0.05). There were more gentamicin-sensitive strains than levofloxacin-sensitive strains identified (P < 0.05). Interestingly, aminoglycoside-inactivating enzyme resistance gene was detected in Enterococcus strains.

Conclusion
Our data suggest that gentamicin-containing perfusion solution can reduce the incidence of postoperative endophthalmitis in cataract patients. However, the selective pressure imposed by gentamicin may facilitate the development of aminoglycoside-resistant Enterococcos strains.

AbstractBackgroundImmunization is an effective preventive health intervention. In Cameroon, the Expanded Program on Immunization (EPI) aims to vaccinate children under 5 years of age for free, but vaccination coverage has consistently remained below the national target. Vaccines are distributed based on the target population size, factoring in wastage norms. However, the vaccine wastage rate (VWR) may differ among various settings. Our study aimed to assess vaccine wastage for different site settings, seasonality, and vaccine types in comparison to vaccination coverage in order to provide comprehensive insights on vaccine wastage.MethodsA retrospective data collection and analysis were conducted on immunization and vaccine wastage data in the Littoral Region of Cameroon during 2016 and 2017. Health districts were classified as urban or rural, seasonality was categorized as rainy or dry season, and vaccine types were grouped into liquid, lyophilized, oral, and injectable vaccines. VWRs and vaccination coverage rates (VCRs) were calculated, and the vaccine waste factor was investigated.ResultsThe VWR of Bacillus Calmette-Guérin (BCG; 32.19%) was the highest, followed by measles and rubella (MR; 19.05%) and yellow fever (YF; 18.34%) among all EPI vaccines in the Littoral Region of Cameroon during 2016 and 2017. Single-dose vaccine vials exhibited lower VWRs than multi-dose vials. Dry season was associated with higher VWRs for most vaccines, although more lyophilized vaccines (BCG, MR, YF vaccines) were wasted in rainy season in 2016. The VWR was persistently higher in rural than urban health districts. The months of February and November saw a decrease in VCRs. The study found an overall negative correlation between VCR and VWR.ConclusionsMultiple factors may cause wastage of EPI vaccines in Cameroon. Vaccination area characteristics, seasonality, types of vaccines such as multi- or single-dose, lyophilized or injectable vaccines are related to VWRs in Littoral Region. Further research on vaccine wastage and vaccination coverage across Cameroon is needed to better understand the socio-behavioral aspect of vaccine in-take that may affect the level of vaccination and vaccine wastage. Public health system strengthening is warranted to adapt more real-time monitoring of the VWR and VCR for each vaccine in the government’s immunization programs.

AbstractBackgroundAddison’s disease is primary adrenal dysfunction and is characterized by decrease of cortisol level and increase of adrenocorticotropic hormone (ACTH) level. It is known that infection is one of main causes of Addison’s disease. Among various infections, tuberculous infection accounts for the majority of them. Recently the number of subjects with non-tuberculous mycobacterial infection has been increased, and the infection can also bring about Addison’s disease.Mycobacterium aviumcomplex (MAC) pulmonary disease accounts for the majority of non-tuberculous mycobacterial infection.Case presentationAn 83-year-old female was suspected of having adrenal failure in our outpatient care and hospitalized in our institution. There was pigmentation in her face, hands and legs, especially in auricle and nail beds in her hands and legs. In rapid ACTH load test (0.25 mg of 1–24 ACTH), cortisol level was not increased at all. An abdominal computed tomography (CT) showed swelling of both adrenal glands accompanied by calcification. QuantiFERON test was negative andmycobacterium tuberculosiscomplex was negative in PCR test using bronchial lung lavage fluid. These data ruled out the possibility of adrenal tuberculosis. It is known that MAC pulmonary disease accounts for the majority of non-tuberculous mycobacterial infection. In this subject, however, anti-MAC antibody was negative and MAC-related bacteria were not detected in PCR test using bronchial lung lavage fluid. These data ruled out the possibility of MAC pulmonary disease.Mycobacterium abscessus(Mab) was positive in bronchial lung lavage fluid culture. Based on these data, we diagnosed this subject with Addison’s disease triggered by infection withmycobacterium abscessus, but not by adrenal tuberculous or MAC pulmonary disease. Decreased sodium level and increased eosinophil number were normalized and appetite loss was markedly mitigated after starting hydrocortisone therapy. A chest CT which was taken about 6 months later showed drastic reduction of consolidation in the upper lobe of the left lung although calcification in the adrenal gland was still observed.ConclusionsWe should bear in mind the possibility of Addison’s disease triggered by another type of infection rather than adrenal tuberculosis or MAC pulmonary disease.

Abstract
Background
Quercetin is an organic flavonoid present in several fruits and vegetables. The anti-inflammatory, antiviral, antioxidant, cardio-protective, anti-carcinogenic and neuroprotective properties demonstrated by this dietary supplement endorses it as a possible treatment for inflammatory diseases and cancer. Unfortunately, conflicting research has cast uncertainties on the toxicity of quercetin. The main purpose of this study was to determine if quercetin has any toxic properties in mice at doses that have shown efficacy in pre-clinical studies regarding cancer, cancer therapy, and their off-target effects.

Methods
A sub-chronic toxicity study of quercetin was examined in male and female CD2F1 mice. Three different doses of quercetin (62, 125, and 250 mg/kg of diet) were infused into the AIN-76A purified diet and administered to mice ad libitum for 98 days. Body weight (BW), food consumption, water intake, body composition, blood count, behavior, and metabolic phenotype were assessed at various timepoints during the course of the experiment. Tissue and organs were evaluated for gross pathological changes and plasma was used to measure alkaline phosphatase (AP), aspartate transaminase (AST), and alanine transaminase (ALT).

Results
We found that low (62 mg/kg of diet), medium (125 mg/kg of diet), and high (250 mg/kg of diet) quercetin feeding had no discernible effect on body composition, organ function, behavior or metabolism.

Conclusions
In summary, our study establishes that quercetin is safe for use in both female and male CD2F1 mice when given at ~ 12.5, 25, or 50 mg/kg of BW daily doses for 14 weeks (i.e. 98 days). Further studies will need to be conducted to determine any potential toxicity of quercetin following chronic ingestion.
Health insurance status of cross-border migrant children and the associated factors: a study in a Thai-Myanmar border area
Authors: Chamchan Chalermpol , Apipornchaisakul Kanya 
Published: October 2022

Abstract
Background
Although policies of Thailand for migrant health protection are inclusive for all migrant groups, due to existing constraints in practices and policy implementation, many migrant children still lack the protection. This study aimed to assess the health insurance status of children aged 0-14 whose parents were cross-border migrant workers in Thailand, and factors related to the status.

Methods
A Thai-Myanmar border area, being developed as a ‘special economic zone’ by the Thai government, was selected as a study site. With a cross-sectional research design, the study collected primary data in late 2018 by a structured questionnaire from 402 migrant households that contained 803 children. The logistic generalized estimating equation (GEE) technique was applied to examine factors associated with the children’s health insurance status. These included socio-economic factors, migration factors, and health insurance-related factors.

Results
It is found that 83.2% of the migrant children did not have health insurance. Factors associated with the health insurance status included age 12-14 years (Odds ratio (OR) 2.34; 95% confidence interval (CI) 1.23-4.46), having a birth certificate (OR 1.89, 95% CI 1.04-3.45), and plan of the family in the future to remain the child in Thailand (OR 2.37, 95% CI 1.09-5.17). The primary carer’s factors that were important health insurance-related factors included having no legal work permit (OR 4.12, 95% CI 1.88-9.06), having health insurance (OR 8.51, 95% CI 3.93-18.41), little or no ability to communicate in Thai (OR 0.31, 95% CI 0.14-0.66), and understanding the right of migrant children to purchase health insurance (OR 2.57, 95% CI 1.52-4.34).

Conclusions
The findings point to the need for every migrant child to have a birth certificate, diminishing language barriers, and providing education and motivation about the need for health insurance for migrants and their accompanying dependents, especially children. For further studies, it is suggested to include migrant health insurance supply-side factors with qualitative analyses to understand how all the factors interactively determine the health insurance status of migrant children.
Potential contribution of early endothelial progenitor cell (eEPC)-to-macrophage switching in the development of pulmonary plexogenic lesion

Abstract
Background
Plexiform lesions, which have a dynamic appearance in structure and cellular composition, are the histological hallmark of severe pulmonary arterial hypertension in humans. The pathogenesis of the lesion development remains largely unknown, although it may be related to local inflammation and dysfunction in early progenitor endothelial cells (eEPCs). We tested the hypothesis that eEPCs contribute to the development of plexiform lesions by differentiating into macrophages in the setting of chronic inflammation.

Methods
The eEPC markers CD133 and VEGFR-2, macrophage lineage marker mannose receptor C-type 1 (MRC1), TNFα and nuclear factor erythroid 2-related factor 2 (Nrf2) in plexiform lesions in a broiler model were determined by immunohistochemistry. eEPCs derived from peripheral blood mononuclear cells were exposed to TNFα, and macrophage differentiation and angiogenic capacity of the cells were evaluated by phagocytotic and Matrigel plug assays, respectively. The role of Nrf2 in eEPC-to-macrophage transition as well as in MRC1 expression was also evaluated. Intratracheal installation of TNFα was conducted to determine the effect of local inflammation on the formation of plexiform lesions.

Results
Cells composed of the early lesions have a typical eEPC phenotype whereas those in more mature lesions display molecular and morphological characteristics of macrophages. Increased TNFα production in plexiform lesions was observed with lesion progression. In vitro studies showed that chronic TNFα challenge directed eEPCs to macrophage differentiation accompanied by hyperactivation of Nrf2, a stress-responsive transcription factor. Nrf2 activation (Keap1 knockdown) caused a marked downregulation in CD133 but upregulation in MRC1 mRNA. Dual luciferase reporter assay demonstrated that Nrf2 binds to the promoter of MRC1 to trigger its expression. In good agreement with the in vitro observation, TNFα exposure induced macrophage differentiation of eEPCs in Matrigel plugs, resulting in reduced neovascularization of the plugs. Intratracheal installation of TNFα resulted in a significant increase in plexiform lesion density.

Conclusions
This work provides evidence suggesting that macrophage differentiation of eEPCs resulting from chronic inflammatory stimulation contributes to the development of plexiform lesions. Given the key role of Nrf2 in the phenotypic switching of eEPCs to macrophages, targeting this molecular might be beneficial for intervention of plexiform lesions.
Comparative study on antimicrobial activity of mono-rhamnolipid and di-rhamnolipid and exploration of cost-effective antimicrobial agents for agricultural applications
Authors: Zhao Feng , Wang Bingxin , Yuan Menglin , Ren Sijia 
Published: October 2022

AbstractBackgroundChemical pesticides have defects in crop diseases control, such as narrow antimicrobial spectrum, chemicals residue risk and harm to farmland ecosystem. Antimicrobial agents from microbial sources are highly interested in agriculture. Studies showed that rhamnolipid biosurfactants possessed certain antimicrobial activity. The structural differences in rhamnolipid inevitably affect their activities. But the antimicrobial effect of mono-rhamnolipid and di-rhamnolipid is unknown. Rhamnolipid with unique structure can be produced using specific microbial cell factory.ResultsDifferent types of rhamnolipid were produced from differentPseudomonas aeruginosastrains. Rha-C10-C10and Rha-Rha-C10-C10were the main homologues in the separated mono-rhamnolipid and di-rhamnolipid, respectively. Both mono-rhamnolipid and di-rhamnolipid exhibited certain antimicrobial activity against the tested microbial strains, especially the fungi and Gram-positive bacteria. But mono-rhamnolipid was superior to di-rhamnolipid, with inhibition zone diameters larger than 25 mm and inhibition rate higher than 90%. The IC50 values of mono-rhamnolipid were lower than 5 mg/L against the tested bacterium and fungus, whereas the IC50 values of di-rhamnolipid were ranged from 10 mg/L to 20 mg/L. Mono-rhamnolipid stimulated the tested strains to generate higher level of intracellular ROS. Mono-rhamnolipid exhibited better antimicrobial activity to the potential agricultural pathogens, such asAlternaria alternata,Pantoea agglomeransandCladosporiumsp. The mono-rhamnolipid crude extract of strainP.aeruginosaSGΔrhlC can replace the separated mono-rhamnolipid. After 50 times dilution, the fermentation broth of the mono-rhamnolipid producing strain SGΔrhlC exhibited equal antimicrobial effect to mono-rhamnolipid (200 mg/L). Prospects of mono-rhamnolipid were also discussed for antimicrobial applications in agriculture.ConclusionsThis work discovered that mono-rhamnolipid was superior to di-rhamnolipid on antimicrobial activity for agricultural applications. Mono-rhamnolipid is an excellent candidate for agricultural biocontrol. The knockout strainP. aeruginosaSGΔrhlC is an excellent microbial cell factory for high producing mono-rhamnolipid. Its mono-rhamnolipid crude extract and its diluted fermentation broth are cost-effective antimicrobial agents. This work provided new insights to develop green and efficient antimicrobial agents for agricultural applications.

Published: October 2022

Abstract
Background
Ferroptosis is an iron-dependent mode of cell death that could be induced by erastin and exert antitumor effects. However, the clinical and biological roles of ferroptosis-related gene (FRG) signature and the therapeutic value of erastin in multiple myeloma (MM) remained unknown.

Methods
Clinical and gene expression data of MM subjects were extracted from the Gene Expression Omnibus (GEO) public database. Univariable cox analysis was applied to determine FRGs related to survival and the least absolute shrinkage and selection operator (LASSO) regression analysis was used to develop a prognostic model. Prediction accuracy of the model was estimated by receiver operating characteristic (ROC) curves. Functional pathway enrichments and infiltrating immune status were also analyzed. We conducted in vitro experiments to investigate the combination therapy of erastin and doxorubicin.

Results
17 FRGs were strongly associated with patient survival and 11 genes were identified to construct the prognostic model. ROC curves indicated great predictive sensitivity and specificity of the model in all cohorts. Patients were divided into low- and high-risk groups by median risk score in each cohort and the survival of the low-risk group was significantly superior than that of the high-risk group. We also observed a close relevance between functional pathways and immune infiltration with risk scores. Moreover, we combined erastin and doxorubicin in our in vitro experiments and found synergetic antitumor effects of the two agents, and the underlying mechanism is the overgeneration of intracellular Reactive Oxygen Species (ROS).

Conclusions
We demonstrated the important value of ferroptosis in patient prognosis and as a potential antitumor target for MM.
Silver nano-reporter enables simple and ultrasensitive profiling of microRNAs on a nanoflower-like microelectrode array on glass

Published: October 2022

AbstractMicroRNAs (miRNAs) are small non-coding RNAs with ~ 22 nucleotides, playing important roles in the post-transcriptional regulation of gene expression. The expression profiles of many miRNAs are closely related to the occurrence and progression of cancer and can be used as biomarkers for cancer diagnosis and prognosis. However, their intrinsic properties, such as short length, low abundance and high sequence homology, represent great challenges in miRNA detection of clinical samples. To overcome these challenges, we developed a simple, ultrasensitive detection platform of electrochemical miRNAs chip (e-miRchip) with a novel signal amplification strategy using silver nanoparticle reporters (AgNRs) for multiplexed, direct, electronic profiling of miRNAs. A two-step hybridization strategy was used to detect miRNAs, where the target miRNA hybridizes with a stem-loop probe to unlock the probe first, and the opened stem-loop can further hybridize with AgNRs for signaling amplification. To enhance the detection sensitivity, the gold nanoflower electrodes (GNEs) were constructed in the microaperture arrays of the e-miRchips by electroplating. With the optimal size of the GNEs, the e-miRchip showed excellent performance for miR-21 detection with a detection limit of 0.56 fM and a linear range extended from 1 fM to 10 pM. The e-miRchip also exhibited good specificity in differentiating the 3-base mismatched sequences of the target miRNA. In addition, the e-miRchip was able to directly detect miR-21 expression in the total RNA extracts or cell lysates collected from lung cancer cells and normal cells. This work demonstrated the developed e-miRchip as an efficient and promising miniaturized point-of-care diagnostic device for the early diagnosis and prognosis of cancers.
