Abstract
Background: Plant height, mainly decided by main stem height, is the major agronomic trait and closely correlated to crop yield. A number of studies had been conducted on model plants and crops to understand the molecular and genetic basis of plant height. However, little is known on the molecular mechanisms of peanut main stem height. Results: In this study, a semi-dwarf peanut mutant was identified from 60 Co γ-ray induced mutant population and designated as semi-dwarf mutant 2 ( sdm2 ). The height of sdm2 was only 59.3% of its wild line Fenghua 1 (FH1) at the mature stage. The sdm2 has less internode number and short internode length to compare with FH1. Gene expression profiles of stem and leaf from both sdm2 and FH1 were analyzed using high throughput RNA sequencing. The differentially expressed genes (DEGs) were involved in hormone biosynthesis and signaling pathways, cell wall synthetic and metabolic pathways. BR, GA and IAA biosynthesis and signal transduction pathways were significantly enriched. The expression of several genes in BR biosynthesis and signaling were found to be significantly down-regulated in sdm2 as compared to FH1. Many transcription factors encoding genes were identified as DEGs. Conclusions: A large number of genes were found differentially expressed between sdm2 and FH1. These results provide useful information for uncovering the molecular mechanism regulating peanut stem height. It could facilitate identification of causal genes for breeding peanut varieties with semi-dwarf phenotype.

Abstract
Background: This study evaluated the impact of multifaceted NPS MedicineWise programs conducted in 2009 and 2015 that targeted general practitioners (GPs) to reduce unnecessary prescribing of proton pump inhibitors (PPIs).

Methods: Time series analyses was conducted of the dispensing rates of concessional PPI scripts between January 2006 and June 2016 using the Pharmaceutical Benefits Scheme (PBS) and Medicare Benefits Schedule (MBS) databases in Australia. Participants were GPs with dispensed PPI prescriptions to concessional patients between January 2006 and June 2016. The interventions were national NPS MedicineWise PPI educational programs in 2009 and 2015 delivered to all practising GPs in Australia. The 2015 intervention coincided with the release of Choosing Wisely Australia recommendations from the Royal Australian College of General Practitioners (RACGP). Outcome measures included monthly dispensing rates of standard and low strength PPIs prescribed by GPs among concessional patients in Australia.

Results : Following the 2009 NPS MedicineWise program we observed a 6.7% reduction in the expected dispensing rate of standard strength PPIs among concessional patients between January 2006 and March 2015, and a total 8.6% reduction by June 2016 following the launch of the 2015 program. We observed a significant increase of 5.6% in the dispensing rate of low strength PPIs among concessional patients between April 2009 and March 2015, and no significant change in trend following the 2015 program.

Conclusions: The NPS MedicineWise programs were associated with reductions in the dispensing rate of standard strength PPIs and with an increase in the dispensing rate of low-strength PPIs by June 2016 although a causal relation was not confirmed. Although the rate of standard strength PPI prescribing is declining, these formulations still constitute the majority of PPIs used in Australia. Regular interventions to sustain and improve PPI management by GPs may be warranted.

Abstract
Background : There is a discrepancy about the metastatic rate of internal mammary lymph nodes (IMNs) between clinical and pathologic findings. We aimed to investigate the metastatic rate of IMNs and to provide recommendations on target volume delineation of IMNs for adjuvant radiotherapy in breast cancer patients. Methods : We retrospectively analyzed data from 114 breast cancer patients treated with surgery without adjuvant radiotherapy who developed local and/or regional lymph node recurrence/metastasis at our institute from January 2015 to January 2019. Patients with widely lung or pleural metastases were excluded. We first analyzed the recurrence rate with the chest wall, the metastatic rate of internal mammary/anterior mediastinal, ipsilateral axillary and supraclavicular lymph nodes, and then investigated the distribution of the IMNs. Results : Among the 114 included patients, the recurrence rate with the chest wall, metastatic rate of IMNs, IMNs/anterior mediastinal lymph nodes, ipsilateral axillary lymph nodes, and the ipsilateral supraclavicular lymph nodes was 43%, 37.7%, 59.6%, 12.3%, and 22.8%, respectively. The metastatic IMNs were mainly located from the first to the second intercostal space. However, metastatic lymph nodes could also be observed above the upper edge of the first rib. Conclusions : The metastatic rate is high in the IMNs and irradiation of the internal mammary lymphatic chain is required. It is suggested that the upper bound of the internal mammary lymphatic chain should be up to the subclavian vein with a 5-mm margin, thus connecting to the caudal border of supraclavicular clinical target volume in breast cancer patients at high risk of recurrence.

Abstract
Background: In low-resource settings with few health workers, Fetal Heart Rate (FHR) monitoring in labour can be inconsistent and unreliable. An initiative to improve fetal monitoring was implemented in two public hospitals in rural Liberia; the country with the second lowest number of midwives and nurses in the world (1.007 per 10,000 of the population). The initiative assessed the feasibility of educating women in labour to monitor their FHR and alert a midwife of changes detected.Methods and Interventions: 474 womenadmitted in labour without obstetric complications were approached. 461 consented to participate (97%) and 13 declined. Those consenting were trained to monitor their FHR using a sonicaid for approximately one minute immediately following the end of every uterine contraction and to inform a midwife of changes. If changes were confirmed, standard clinical interventions for fetal distress (lateral tilt, intravenous fluids and oxygen) were undertaken and, when appropriate, accelerated delivery by vacuum or Caesarean section. Participants provided views on their experiences; subsequently categorized into themes. Neonatal outcomes regarding survival, need for resuscitation, presence of birth asphyxia, and treatment were recorded.Results: 461 out of 474 women gave consent, of whom 425 (92%) completed the monitoring themselves. 387 of 400 women who gave comments, reported positive and 13 negative experiences.28 participants reported FHR changes, confirmed in 26 cases with meconium stained liquor in 17. Fetal death was identified on admission during training in one mother. 13 neonates required resuscitation, with 10 admitted to the neonatal unit. One developed temporary seizures suggesting birth asphyxia. All 26 neonates were discharged home apparently well. In 2 mothers, previously unrecognized obstetric complications (cord prolapse and Bandl’s ring with obstructed labour) accompanied FHR changes. Resuscitation was needed in 8 neonates without identified FHR changes including one of birth weight 1.3 Kg who could not be resuscitated. There were no intrapartum stillbirths in participants. Conclusions: Women in labour were able to monitor and detect changes in their FHR. Most found the experience beneficial. The absence of intrapartum stillbirths after admission and the low rate of poor neonatal outcomes are promising and warrant further investigation.

Abstract
Background Copy Number Variations (CNVs) are gain or loss of DNA segments that are known to play a role in shaping a wide range of phenotypes. In this study, we used two dairy cattle populations, Holstein Friesian and Jersey, to discover CNVs using the Illumina BovineHD Genotyping BeadChip aligned to the ARS-UCD1.2 assembly. The discovered CNVs were investigated for their functional impact and their population genetics features.
Results We discovered 14,272 autosomal CNVs, which were aggregated into 1,755 CNV regions (CNVR) from 451 animals. These CNVRs together cover 2.8% of the bovine autosomes. The assessment of the functional impact of CNVRs showed that rare CNVRs (MAF < 0.01) are more likely to overlap with genes, than common CNVRs (MAF ≥ 0.05). The Population differentiation index (Fst) based on CNVRs revealed multiple highly diverged CNVRs between the two breeds. Some of these CNVRs overlapped with candidate genes such as MGAM and ADAMTS17 genes , which are related to starch digestion and body size, respectively. Lastly, linkage disequilibrium (LD) between CNVRs and BovineHD BeadChip SNPs was generally low, close to 0, although common deletions (MAF ≥ 0.05) showed slightly higher LD ( r 2 =~0.1 at 10kb distance) than the rest. Nevertheless, this LD is still lower than SNP-SNP LD ( r 2 =~0.5 at 10kb distance).
Conclusions Our analyses showed that CNVRs detected using BovineHD BeadChip arrays are likely to be functional. This finding indicates that CNVs can potentially disrupt the function of genes and thus might alter phenotypes. Also, the population differentiation index revealed two candidate genes, MGAM and ADAMTS17 , which hint at adaptive evolution between the two populations. Lastly, low CNVR-SNP LD implies that genetic variation from CNVs might not be fully captured in routine animal genetic evaluation, which relies solely on SNP markers.

How many words are Australian children hearing in the first year of life?
Authors: Brushe Mary E , Lynch John W. , Reilly Sheena , Melhuish Edward , Brinkman Sally A. 
Published: January 2020

Abstract
Background: There is evidence that parents from more socioeconomically disadvantaged backgrounds engage in fewer verbal interactions with their child than more advantaged parents. This leads to the so-called, ‘30 million-word gap’. We used improved technology to investigate the number of words children hear in their first year of life. Methods: Mothers were recruited into a five-year prospective cohort study and categorized into either high or low maternal education groups. Data was derived from the first two waves of the study, when the children were six and twelve months old. At both waves, children were involved in day-long audio recordings using the Language Environment Analysis software that provided automatic counts of adult words spoken to the child, child vocalizations and conversational turns. Descriptive results are presented by maternal education groups. Results: There was large variation within each maternal education group, with the number of adult words spoken to the child ranging from 2,958 to 39,583 at six months and 4,389 to 45,849 at twelve months. There were no meaningful differences between adult words, child vocalizations or conversational turns across maternal education groups at either wave of data collection. Conclusions: These results show that a word gap related to maternal education is not apparent up to twelve months of age. The large variability among both maternal education groups suggests that universal interventions that encourage all parents to talk more to their child may be more appropriate than interventions targeted towards disadvantaged families during the first year of life.
Putting RFMix and ADMIXTURE to the test in a complex admixed population
Authors: Uren Caitlin , Hoal Eileen G. , Möller Marlo 
Published: January 2020

Abstract
Background Global and local ancestry inference in admixed human populations can be performed using computational tools implementing distinct algorithms. The development and resulting accuracy of these tools has been tested largely on populations with relatively straightforward admixture histories but little is known about how well they perform in more complex admixture scenarios. Results Using simulations, we show that RFMix outperforms ADMIXTURE in determining global ancestry proportions even in a complex 5-way admixed population, in addition to assigning local ancestry with an accuracy of 89%. RFMix’s ability to determine global and local ancestry to a high degree of accuracy, particularly in admixed populations provides the opportunity for more accurate association analyses. Conclusion This study highlights the utility of the extension of computational tools to become more compatible to genetically structured populations, as well as the need to expand the sampling of diverse world-wide populations. This is particularly noteworthy as modern-day societies are becoming increasingly genetically complex and some genetic tools and commonly used ancestral populations are less appropriate. Based on these caveats and the results presented here, we suggest that RFMix be used for both global and local ancestry estimation in world-wide complex admixture scenarios particularly when including these estimates in association studies.

Published: January 2020

Abstract
Background: Bolivia has the highest prevalence of cervical cancer in South America and the prevalence of viral sexually transmitted infections (STIs) among people in urban cities is increasing. Little is known about the prevalence of viral STIs in rural communities, which generally have limited access to health care. In order to study the prevalence of viral STIs in rural Bolivia, we recruited women from villages and towns in the Department of La Paz in Bolivia. Methods: 394 female participants were assessed for IgG-antibodies to herpes simplex virus type 2 (HSV-2), human immunodeficiency virus (HIV) and hepatitis B virus (HBV, anti-HBc), as well as for the presence of HBV surface antigen (HBsAg) in dried blood spots. The prevalence of 12 high-risk types of human papillomavirus (HPV) was assessed by qPCR in dried cervicovaginal cell spots from 376 of these women. χ 2 test was used to compare variables between the populations and binary logistic regression was used to identify risk factors associated with the positivity of the tests. Results: The seroprevalence of HSV-2 was 53% and of HBV 10.3%. HBAg was detected in 15.8% of women with anti-HBV antibodies indicating chronic infection. The frequency of high-risk HPV infection was 27%, with the most prevalent high-risk HPV types being HPV 56, 39 and 31 followed by HPV 16 and 18. Finally, none of the 394 women were seropositive for HIV, and about 64% of the studied population was positive for at least one of the viral infections. Conclusions: Women in Bolivian rural communities in La Paz show a high prevalence of HBV, HPV and, in particular, HSV-2. In contrast, none of the women were HIV positive, suggesting that the HIV prevalence in this population is low. The pattern of high-risk HPV types differed from many other countries with a predominance of HPV-types not included in the Gardasil vaccine which was officially introduced in Bolivia in April 2017. Key words : Prevalence, Sexually transmitted infections, women, La Paz, Bolivia, rural communities, HSV-2, HIV, high-risk HPV, HBV.

Abstract
Background: Musculoskeletal disorders are prevalent among waste collectors in developing countries. This study aimed to investigate the prevalence of musculoskeletal disorders and risk factors of persistent musculoskeletal disorders among waste collectors in Hanoi, Vietnam. Methods: A cross-sectional survey was utilized to study 331 waste collectors in 2017. The Örebro Musculoskeletal Pain Questionnaire and questionnaires on demographic and work conditions were used to collect data. Descriptive and Linear regression analyses were applied at the significant level p<0.05. Findings: Results showed that the prevalence of musculoskeletal disorders among waste collectors participating into this study was high (100%), multiple-site musculoskeletal disorders (at least two sites) were reported by 81%. Lower back was the most affected site, followed by pain in the neck and shoulders. The risk of persistent musculoskeletal disorders were higher among female workers, workers with the neck bent at an angle of 450, kneeling, repetitive medial rotation while walking, and feeling dissatisfaction with work, stress or anxiety during one week before the survey. Conclusions: High prevalence of musculoskeletal disorders was observed among participated waste collectors and it associated with self-assessed unfavorable work postures and psychological stress at work. The findings imply the need of mechanical and social support at work for waste collectors to prevent the development of musculoskeletal disorders.

Abstract
Background This study aims to investigate the epidemiologic characteristics and variational trends following a hepatitis B vaccine (HepB) inoculation programme carried out in children over the last 22 years in Jiangsu province. It also aims to evaluate the effect of hepatitis B vaccine immunisation and to analyse the influential of HBsAg positive carriers. Finally, the study also provides reliable data and a baseline for adjusting future prevention and intervention strategies in Jiangsu province. Methods The incidence rates of hepatitis B virus (HBV) in Jiangsu province from 2004 to 2014 were obtained from the National Notifiable Disease Reporting System (NNDRS). A stratified cluster random sampling method was used to select 3,002 subjects aged 1-29 years across 13 hepatitis B virus monitoring points throughout the province, which had been classified as either urban or rural. HBV was assessed from venous blood samples using Abbott microparticle enzyme immunoassay (MEIA) kits (Abbott Laboratories, Chicago, Illinois). Results HBV incidence in the 1-29 age group showed a significant downward trend since 2004 (P<0.001). Serological assessments showed that the prevalence values of the hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (anti-HBc) in the 1-29 age group were 1.20% and 5.33%, respectively. And 66.89% tested positive for the hepatitis B surface antibody (anti-HBs). The HBsAg positive rate among participants was significantly lower in subjects who had been vaccinated than in those who had not (0.46% vs 14.93%, p<0.0001). Among persons who had received the full three-dose vaccine regimen, 90.93% received the first dose of the HBV vaccine within 24 hours of the baby’s birth. In this same group, the prevalence rates of HBsAg and anti-HBc were 0.05% and 0.95%, respectively, and the HBV infection rate decreased significantly after 2006. Conclusions The overall rate of Hepatitis B vaccinations and vaccinations administered within 24 hours of the baby’s birth have continuously improved since the HepB vaccine was integrated into the immunisation programme in Jiangsu province. Hepatitis B prevention and control works in the target population has achieved remarkable results.

Abstract
Background With the fast-paced aging and increasing digitalization of society, there has been a growing interest in the effect of mobile device use on cognitive function and depression in older adults. However, research examining this issue among older adults in residential care homes (RCHs) is scant. Therefore, this study aimed to examine the impact of mobile device use on the cognitive function and depressive symptoms of older adults living in RCHs.
Methods A cross-sectional survey was conducted using a sociodemographic questionnaire, the Montreal Cognitive Assessment (MoCA) and the 15-item Geriatric Depression Scale (GDS-15).
Results A total of 235 senior residents (aged 82.58 ± 5.54) in four RCHs were surveyed. Users of mobile devices had a significantly higher total MoCA score (25.02 ± 4.14) and a significantly lower GDS-15 score (3.28±2.74) than non-users (MoCA: 19.34 ± 5.21, GDS-15: 4.69±2.90). Multivariate linear regression indicate that mobile device use is significantly associated with total MoCA score, six of the seven sub-scores (visuospatial abilities and execution functions, attention, language, abstraction, delayed recall, and orientation)(P<0.05). Logistic regression showed that mobile device use was significantly associated with the level of depressive symptoms (OR=0.458, 95%CI=0.249-0.845).
Conclusions Use of mobile devices has a significant association with the cognitive function and depressive symptoms of older adults living in RCHs, and thus should be encouraged as a measure to maintain and improve cognition and prevent depression.
