AbstractBackgroundFlavanone 3-hydroxylase (F3H), a key enzyme in the flavonoid biosynthetic pathway, plays an important role in the regulation of flavonols and anthocyanidins accumulation. Citrus fruit is a rich source of flavonoids with varied flavonoid compositions among different varieties. To date, the study onF3His limited in citrus, and its roles in regulating flavonoid accumulation in citrus fruit are still unclear.ResultsIn this study, we isolated aCitF3Hfrom three different citrus varieties, Satsuma mandarin (Citrus unshiuMarc.), Ponkan mandarin (C.reticulataBlanco) and blood orange ‘Moro’ (C.sinensisOsbeck). Functional analysis showed thatCitF3Hencoded a functional flavanone 3-hydroxylase. It catalyzed the hydroxylation of naringenin to yield dihydrokaempferol, which was a precursor of anthocyanins in flavonoid biosynthetic pathway. In the juice sacs,CitF3Hwas differentially expressed among the three citrus varieties, and its expression level was positively correlated with the accumulation of anthocyanins during the ripening process. In the juice sacs of Satsuma mandarin and Ponkan mandarin the expression ofCitF3Hkept constant at an extremely low level, and no anthocyanin was accumulated during the ripening process. In contrast, the expression ofCitF3Hincreased rapidly along with the accumulation of anthocyanin in the juice sacs of blood orange ‘Moro’ during the ripening process. In addition, we found that blue light irradiation was effective to up-regulate the expression ofCitF3Hand improve anthocyanin accumulation in the juice sacs of blood orange ‘Moro’ in vitro.ConclusionCitF3Hwas a key gene regulating anthocyanin accumulation in the juice sacs of citrus fruit. The results presented in this study will contribute to elucidating anthocyanin biosynthesis in citrus fruit, and provide new strategies to improve the nutritional and commercial values of citrus fruit.

Abstract
Background
To evaluate the role of a standardized first-trimester scan in screening different kinds of central nervous system malformations and to report a 3-year experience from a tertiary center using an unselected cohort.

Methods
This was a retrospective analysis of prospectively collected data from a single center evaluating first-trimester scans with predesigned standardized protocols performed between 1 May 2017 and 1 May 2020, involving 39,526 pregnancies. All pregnant women underwent a series of prenatal ultrasound scans at 11–14, 20–24, 28–34 and 34–38 weeks of gestation. Abnormalities were confirmed by magnetic resonance imaging, postmortem examination or trained ultrasound professionals. Pregnancy outcomes and some postnatal follow-up were obtained from maternity medical records and telephone calls.

Results
A total of 38,586 pregnancies included in the study. The detection rates of CNS anomalies by ultrasound in the first, second, third and late third trimester were 32%, 22%, 25%, and 16%, respectively. And there were 5% of CNS anomalies missed by prenatal ultrasound. In the first-trimester scan, we diagnosed all cases of exencephaly, anencephaly, alobar holoprosencephaly and meningoencephalocele, and some cases of posterior cranial fossa anomalies (20%), open spina bifida (67%), semilobar holoprosencephaly (75%) and severe ventriculomegaly (8%). Vein of Galen aneurysmal malformation, closed spina bifida, lobar holoprosencephaly, intracranial infection, arachnoid cyst, agenesis of the corpus callosum, cysts of the septum pellucidum and isolated absence of the septum pellucidum were never detected during the first trimester. The abortion rates of fetal CNS anomalies detected by first-trimester scan, second-trimester scan, and third- trimester scan were 96%, 84% and 14%, respectively.

Conclusions
The study showed that almost 1/3 of central nervous system anomalies were detected by the standard first-trimester scan and these cases were associated with a high rate of abortion. Early screening for fetal abnormalities gives parents more time for medical advice and safer abortion if needed. It is therefore recommended that some major CNS anomalies should be screened in the first trimester. The standardized anatomical protocol, consisting of four fetal brain planes, were recommended for routine first trimester ultrasound screening.

Abstract
Background
Laparoscopic surgery (LS) has been increasingly applied in perihilar cholangiocarcinoma (pCCA). In this study, we intend to compare the short-term outcomes of LS versus open operation (OP) for pCCA in a multicentric practice in China.

Methods
This real-world analysis included 645 pCCA patients receiving LS and OP at 11 participating centers in China between January 2013 and January 2019. A comparative analysis was performed before and after propensity score matching (PSM) in LS and OP groups, and within Bismuth subgroups. Univariate and multivariate models were performed to identify significant prognostic factors of adverse surgical outcomes and postoperative length of stay (LOS).

Results
Among 645 pCCAs, 256 received LS and 389 received OP. Reduced hepaticojejunostomy (30.89% vs 51.40%, P = 0.006), biliary plasty requirement (19.51% vs 40.16%, P = 0.001), shorter LOS (mean 14.32 vs 17.95 d, P < 0.001), and lower severe complication (CD ≥ III) (12.11% vs. 22.88%, P = 0.006) were observed in the LS group compared with the OP group. Major postoperative complications such as hemorrhage, biliary fistula, abdominal abscess, and hepatic insufficiency were similar between LS and OP (P > 0.05 for all). After PSM, the short-term outcomes of two surgical methods were similar, except for shorter LOS in LS compared with OP (mean 15.19 vs 18.48 d, P = 0.0007). A series subgroup analysis demonstrated that LS was safe and had advantages in shorting LOS.

Conclusion
Although the complex surgical procedures, LS generally seems to be safe and feasible for experienced surgeons.

Abstract
Background
We aimed to assess the trends in urinary tract infections (UTIs) and prognosis of patients with prostate cancer after radical prostatectomy (RP) and radiation therapy (RT) as definitive treatment options.

Methods
The data of patients diagnosed with prostate cancer between 2007 and 2016 were collected from the National Health Insurance Service database. The incidence of UTIs was evaluated in patients treated with RT, open/laparoscopic RP, and robot-assisted RP. The proportional hazard assumption test was performed using the scaled Schoenfeld residuals based on a multivariable Cox proportional hazard model. Kaplan–Meier analysis were performed to assess survival.

Results
A total of 28,887 patients were treated with definitive treatment. In the acute phase (< 3 months), UTIs were more frequent in RP than in RT; in the chronic phase (> 12 months), UTIs were more frequent in RT than in RP. In the early follow-up period, the risk of UTIs was higher in the open/laparoscopic RP group (aHR, 1.63; 95% CI, 1.44–1.83; p < 0.001) and the robot-assisted RP group (aHR, 1.26; 95% CI, 1.11–1.43; p < 0.001), compared to the RT group. The robot-assisted RP group had a lower risk of UTIs than the open/laparoscopic RP group in the early (aHR, 0.77; 95% CI, 0.77–0.78; p < 0.001) and late (aHR, 0.90; 95% CI, 0.89–0.91; p < 0.001) follow-up periods. In patients with UTI, Charlson Comorbidity Index score, primary treatment, age at UTI diagnosis, type of UTI, hospitalization, and sepsis from UTI were risk factors for overall survival.

Conclusions
In patients treated with RP or RT, the incidence of UTIs was higher than that in the general population. RP posed a higher risk of UTIs than RT did in early follow-up period. Robot-assisted RP had a lower risk of UTIs than open/laparoscopic RP group in total period. UTI characteristics might be related to poor prognosis.

Abstract
Background
Childhood obesity is a serious public health concern that confers a greater risk of developing important comorbidities such as MetS and T2DM. Recent studies evidence that gut microbiota may be a contributing factor; however, only few studies exist in school-age children. Understanding the potential role of gut microbiota in MetS and T2DM pathophysiology from early stages of life might contribute to innovative gut microbiome-based interventions that may improve public health. The main objective of the present study was to characterize and compare gut bacteria of T2DM and MetS children against control subjects and determine which microorganisms might be potentially related with cardiometabolic risk factors to propose gut microbial biomarkers that characterize these conditions for future development of pre-diagnostic tools.

Results
Stool samples from 21 children with T2DM, 25 with MetS, and 20 controls (n = 66) were collected and processed to conduct 16S rDNA gene sequencing. α- and β-diversity were studied to detect microbial differences among studied groups. Spearman correlation was used to analyze possible associations between gut microbiota and cardiometabolic risk factors, and linear discriminant analyses (LDA) were conducted to determine potential gut bacterial biomarkers. T2DM and MetS showed significant changes in their gut microbiota at genus and family level. Read relative abundance of Faecalibacterium and Oscillospora was significantly higher in MetS and an increasing trend of Prevotella and Dorea was observed from the control group towards T2DM. Positive correlations were found between Prevotella, Dorea, Faecalibacterium, and Lactobacillus with hypertension, abdominal obesity, high glucose levels, and high triglyceride levels. LDA demonstrated the relevance of studying least abundant microbial communities to find specific microbial communities that were characteristic of each studied health condition.

Conclusions
Gut microbiota was different at family and genus taxonomic levels among controls, MetS, and T2DM study groups within children from 7 to 17 years old, and some communities seemed to be correlated with relevant subjects’ metadata. LDA helped to find potential microbial biomarkers, providing new insights regarding pediatric gut microbiota and its possible use in the future development of gut microbiome-based predictive algorithms.

Abstract
Background
Childhood anemia is an important public health problem in Ethiopia. The northeast part of the country is among the areas affected by recurrent drought. Despite its significance, studies are scarce on childhood anemia particularly, in the study area. This study aimed to assess the proportion and factors associated with anemia among under-five children in Kombolcha town.

Methods
A facility-based cross-sectional study was conducted among 409 systematically selected 6 to 59 months aged children visited health institutions in Kombolcha town. Data were collected using structured questionnaires from mothers/caretakers. The data entry and analysis were done using EpiData version 3.1 and SPSS version 26 respectively. Binary logistic regression was fitted to identify factors associated with anemia. Statistical significance was declared at p-value ≤ 0.05. The effect size was reported using the adjusted odds ratio with its 95% confidence interval.

Results
Of the participants, 213(53.9%) were males with a mean age of 26 months (SD ± 15.2). The proportion of anemia was 52.2% (95% CI, 46.8-57%). Being in the age of 6–11 months (AOR = 6.23, 95% CI: 2.44, 15.95), 12–23 months (AOR = 3.74, 95%CI: 1.63, 8.60), having low dietary diversity score (AOR = 2.61, 95% CI: 1.55, 4.38), having a history of diarrhea (AOR = 1.87, 95% CI: 1.12, 3.12) and having the lowest family monthly income (AOR = 16.97, 95% CI: 4.95, 58.20) were positively associated with anemia. Whereas, maternal age ≥ 30 years (AOR = 0.37 (0.18, 0.77) and exclusive breastfeeding until six months (AOR = 0.27, 95% CI: 0.16, 0.45) were negatively associated with anemia.

Conclusions
Childhood anemia was a public health problem in the study area. Child age, maternal age, exclusive breastfeeding, dietary diversity score, diarrhea, and family income were significantly associated with anemia.
Inequality in quality-adjusted life expectancy by educational attainment in Norway: an observational study
Authors: Gutacker Nils , Kinge Jonas Minet , Olsen Jan Abel 
Published: May 2023

Abstract
Background
Health inequalities are often assessed in terms of life expectancy or health-related quality of life (HRQoL). Few studies combine both aspects into quality-adjusted life expectancy (QALE) to derive comprehensive estimates of lifetime health inequality. Furthermore, little is known about the sensitivity of estimated inequalities in QALE to different sources of HRQoL information. This study assesses inequalities in QALE by educational attainment in Norway using two different measures of HRQoL.

Methods
We combine full population life tables from Statistics Norway with survey data from the Tromsø study, a representative sample of the Norwegian population aged ≥ 40. HRQoL is measured using the EQ-5D-5L and EQ-VAS instruments. Life expectancy and QALE at 40 years of age are calculated using the Sullivan-Chiang method and are stratified by educational attainment. Inequality is measured as the absolute and relative gap between individuals with lowest (i.e. primary school) and highest (university degree 4 + years) educational attainment.

Results
People with the highest educational attainment can expect to live longer lives (men: + 17.9% (95%CI: 16.4 to 19.5%), women: + 13.0% (95%CI: 10.6 to 15.5%)) and have higher QALE (men: + 22.4% (95%CI: 20.4 to 24.4%), women: + 18.3% (95%CI: 15.2 to 21.6%); measured using EQ-5D-5L) than individuals with primary school education. Relative inequality is larger when HRQoL is measured using EQ-VAS.

Conclusion
Health inequalities by educational attainment become wider when measured in QALE rather than LE, and the degree of this widening is larger when measuring HRQoL by EQ-VAS than by EQ-5D-5L. We find a sizable educational gradient in lifetime health in Norway, one of the most developed and egalitarian societies in the world. Our estimates provide a benchmark against which other countries can be compared.

Published: May 2023

Abstract
Background
Food insecurity is a common public health problem in both developed and developing countries. This study aimed to profile food insecurity among university students in a developed country with stable economic circumstances (Germany) and a developing Mediterranean country undergoing a severe economic and financial crisis (Lebanon) and examine the associations between food insecurity and lifestyle behaviors (i.e., physical activity, sleep, and adherence to a healthy eating pattern, such as the Mediterranean diet), stress, and financial well-being.

Method
This online cross-sectional study was conducted between September 2021 and March 2022. Subjects were recruited through social media platforms (Facebook, WhatsApp, Instagram, and personal email) and in-class announcements by several university professors of various majors and from different universities in Lebanon and Germany. The final sample included 547 participants (197 from Lebanon and 350 from Germany).

Results
Our findings showed a higher food insecurity rate in Lebanon compared with Germany (59% versus 33%). In the bivariate analysis, food insecurity was associated with insomnia (r = 0.230; p < 0.001) and stress (r = 0.225; p = 0.001); German university students had higher physical activity (p < 0.001), better diet quality (p < 0.001), and lower adherence to the Mediterranean diet (p < 0001) than Lebanese students. In the multivariable analyses, more stress was related to insomnia (B = 0.178; p < 0.001), while financial well-being was not associated with any of the lifestyle behaviors. Physical activity, insomnia, and Mediterranean diet adherence were not associated with the country or food insecurity (p > 0.05); however, living in Germany was associated with better diet quality (B = -7.85; p < 0.001).

Conclusion
The high prevalence of food insecurity reported in this study is alarming, particularly among Lebanese students; German students had better diet quality and higher physical activity but worse adherence to the Mediterranean diet. Moreover, food insecurity was also associated with worse sleep and stress. Further studies are necessary to assess the role of food insecurity as a mediating factor between sociodemographic characteristics and lifestyle behaviors.

Abstract
Background
Poor knowledge and awareness of cervical cancer screening and vaccination are significant barriers to effective cervical cancer prevention in developing countries. Knowledge of cervical cancer and vaccination against cervical cancer remains low in Nigeria. The purpose of this study was to assess the knowledge, awareness, and attitude of female staff of Afe Babalola University towards cervical cancer screening and vaccinations.

Methods
This study was a cross-sectional study conducted using a semi-structured questionnaire among female staff of Afe Babalola University, Ado-Ekiti, Ekiti State, Nigeria. The workers’ knowledge and awareness were assessed using yes and no questions while the attitude was assessed using Likert scale questions. The workers’ knowledge was ranked as good (≥ 50%) and poor (< 50%) while attitude was ranked as positive (≥ 50%) and negative (< 50%). The relationship between demographics, attitude and knowledge of cervical cancer screening and vaccination was carried out using the Chi-square test. Analyses were conducted using SPSS software version 20.

Results
A total of 200 staff consented to participate in the study out of which 64% were married with mean age 32.81 ± 8.164 years. Majority (60.5%) of the participants knew the causes of cervical cancer while 7.5% strongly agreed that they do not see the need for cervical screening. Majority (63.5%) of the participants showed good knowledge while 46% had a positive attitude towards cervical cancer screening and vaccination.

Conclusions
The study participants showed good knowledge and awareness but poor attitude towards cervical cancer screening and vaccinations. Interventions and continuous education are needed to improve the population’s attitude and eliminate misconceptions.

Published: May 2023

AbstractIntroductionPelvic organ prolapse (POP) affects women’s quality of life in various aspects. However, evidence on the healthcare-seeking behavior of women with POP is limited. Therefore, this review aimed to identify and synthesize the existing evidence on the healthcare-seeking behavior among women with POP.MethodsThis systematic review and narrative synthesis of the literature on healthcare-seeking behavior among women with POP was conducted from 20 June to 07 July 2022. The electronic databases PubMed, African Journals Online, Cumulative Index to Nursing and Allied Health Literature, African Index Medicus and Directory of Open Access Journal, and Google Scholar were searched for relevant literature published from 1996 to April 2022. The retrieved evidence was synthesized using a narrative synthesis approach. The characteristics of included studies and the level of healthcare-seeking behavior were summarized in a table and texts. Error bar was used to show the variability across different studies.ResultsA total of 966 articles were retrieved of which only eight studies with 23,501 women (2,683 women with pelvic organ prolapse) were included in the synthesis. The level of healthcare-seeking behavior ranges from 21.3% in Pakistan to 73.4% in California, USA. The studies were conducted in four different populations, used both secondary and primary data, and were conducted in six different countries. The error bar shows variation in healthcare-seeking behavior.ConclusionsThe level of health-care seeking behavior among women with POP is low in low-income countries. There is substantial variability in the characteristics of the reviewed studies. We recommend a large-scale and robust study which will help to better understand the healthcare-seeking behavior among women with POP.
