Background: Stunting is a problem that still occurs in Indonesia. It is a chronic nutritional problem associated with insufficient food intake so that nutritional needs are not fulfilled over a long period. Stunting also can be caused by indirect factors such as environmental and behavioral. Aims: This study aimed to analyze the correlation of child caregivers’ personal hygiene implementation and family smoking behavior on the occurrence of stunting. Methods: This type of research is an analytic survey with a case-control study approach. The number of respondents was 25 cases and 25 controls so the total number of respondents was 50 respondents. Results: The results of the examination found that personal hygiene of caregivers and smoking habits in the families of stunted toddlers were mostly inadequate and there was a smoking habit in the families of stunted toddlers. There is a significant relationship between defecation behaviors and the incidence of stunting with a p-value of 0.02 (<0.05). Based on multivariate analysis, it was found that unqualified defecation behaviors had a 63.3% probability of stunting. Conclusion: There is a significant correlation between defecation behaviors and the occurrence of stunting with a p-value of 0.02 (<0.05). According to multivariate analysis, respondents with defecation behaviors that did not meet the standards had a 4.03 times greater risk of having a child with stunting.

Published: March 2024

Les métiers des filières d’élevage souffrent d’un manque d’attractivité. Un groupe de travail du GIS Avenir Élevages s’est donné pour objectif d’analyser ce manque d’attractivité afin d’y remédier. Ce groupe a conduit de nombreuses enquêtes qualitatives et quantitatives entre 2019 et 2021 pour répondre à plusieurs questions : Quels sont, aujourd’hui, les métiers de l’élevage en tension et quels sont leurs facteurs d’attractivité ? Quelles sont les attentes des personnes susceptibles de les exercer ? Comment pourront évoluer les métiers des filières de l’élevage et leur attractivité d’ici 10 à 15 ans ? Dans un premier temps, un état des lieux des métiers en tension et de leurs facteurs d’attractivité a été réalisé à partir de la bibliographie et d’entretiens auprès d’acteurs des filières d’élevage. Des freins à l’attractivité, communs aux différents métiers, ont été mis en évidence : leur image est mitigée, la rémunération est faible, les conditions de travail sont perçues comme difficiles, et leur accès peut être compliqué. Toutefois, certaines caractéristiques de ces métiers attirent les jeunes, comme le contact avec les animaux et la diversité des tâches inhérents au secteur de l’amont, et le sentiment d’être utile à la société. Dans un second temps, un travail prospectif à moyen terme a été réalisé avec un groupe d’experts et de professionnels de l’élevage. Les métiers de l’élevage ont été décrits dans quatre scénarios prospectifs : un scénario « anti-élevage » ; un scénario « alternatif » ; un scénario « libéral » ; et un scénario « diversification et montée en gamme de l’élevage ». Ces travaux invitent à réfléchir à des pistes d’amélioration de l’attractivité des filières d’élevage, comme une meilleure communication sur la diversité des métiers qu’elles proposent et une amélioration des conditions de travail.

This study aims to determine the projections of the number of school-age residents; ages 7-12 years, ages 13-15 years, and ages 16-18 years; in 2018 to 2025 based on the number of school-age population in 2015, 2016, and 2017. The study also projects the number of students in primary education (SD/ MI and SMP/ MTs) and secondary education (SMA/ SMK/ MA) based on the growing trend of the school-age population. Eventually, the study also calculates the projections of teacher and the projections of infrastructure. The study used a quantitative approach with descriptive methods by describing the documentation and interviews. The study was in Sukamakmur Sub-District, Bogor Regency. The result shows that the growth of the elementary age population,7-12 years, has decreased every year. Conversely, secondary school-age population increase every year. Regarding student projections, it is found that there is a difference between the number of students and the number of school-aged residents attending school at the appropriate level. The result also shows that there are some people who are not aged 7-12 attending primary education.  The same thing happened to the high school level. This indicates that there are many junior high school graduates who do not continue their education to the senior high school level. Regarding teacher projections of elementary school teachers, the ideal ratio of teachers: students are 1:20, but the reality is 1:29. This shows that it is necessary to add the number of teachers to elementary schools in order to achieve the ideal ratio for the sake of effectiveness of learning. In contrast,  junior and senior high school that already meets the ideal ratio, where for junior and senior high school are 1:15 and 1:12 respectively. This shows that there are excess numbers of teachers at the junior and senior high school level. Therefore, it is necessary to increase school enrollment rates

Published: March 2024

Heterocycle skeletal editing has recently experienced a renaissance in chemical synthesis by offering a simple retrosynthetic disconnection between complex structural scaffolds and simple starting materials. However, asymmetric dearomatization of heteroarenes through single atom “cut and paste” remains unknown to date. Herein, we report the first enantiodivergent dearomative skeletal editing of indoles via single-carbon-atom insertion using trifluoromethyl N-triftosylhydrazones as carbene precursors. This strategy provides a straightforward methodology to access both enantiomers of 3,4-dihydroquinolines containing a trifluoromethylated quaternary stereocenter by switching the chirality of catalyst. The synthetic utility and enantiodivergent nature of this methodology were demonstrated by scope evaluation, product derivatization, and the short synthesis of drug analogues. Mechanistic studies disclose that selectivity and asymmetric induction are under catalyst control during the initial cyclopropanation step.

Published: March 2024

Futuristic technologies like morphing aircrafts and superstrong artificial muscles are hinged on metal alloys being as strong as an ultrahigh-strength steel (with a high yield strength σy >1 GPa) yet as flexible as a polymer (with an ultralow elastic modulus E ~10 GPa)1-3. However, achieving such “strong yet flexible” alloys has proven challenging4-9. The difficulty lies in an inevitable trade-off between strength and flexibility5,8,10, which precludes a high-strength alloy from being of polymer-like ultralow modulus. Here we report a Ti-50.8 at.% Ni strain glass alloy showing an unprecedented combination of an ultrahigh yield strength σy ~1.8 GPa with a polymer-like ultralow elastic modulus E ~10.5 GPa, together with a superlarge rubber-like J-shaped elastic strain of ~8%. As a result, it possesses the highest flexibility figure of merit σy/E ~0.17 which far exceeds that of existing structural materials. This alloy was fabricated by a simple 3-step thermomechanical treatment, which leads to not only ultrahigh strength but also ultralow modulus through forming a unique “dual-seed strain glass” (DS-STG) microstructure, being a strain glass matrix embedded with a small amount of R and B19' martensites. In-situ x-ray diffractometry reveals that the DS-STG enables a nucleation-free reversible transition between strain glass and R and B19’ martensites during stress loading/unloading, thereby leading to ultralow modulus and large recoverable strain with narrow hysteresis. Our finding may open a new horizon for designing and mass-producing strong and flexible alloys and such alloys may lead to important applications.

Published: March 2024

Purpose To evaluate the efficacy of ultrasound guided ruthenium (Ru 106) plaque brachytherapy for treatment of exudative retinal detachment in diffuse choroidal haemangioma (DCH).Methods Retrospective analysis of four paediatric patients treated with ultrasound guided Ru 106 plaque brachytherapy for DCH with total exudative retinal detachment directed to the thickest part of the DCH. A dose of 40 Gy to the tumour apex was delivered in all patients. The outcomes of treatment were regression of DCH, resolution of retinal detachment, development of neo-vascular glaucoma or any other radiation associated complications which were assessed clinically and with B scan ultrasonography.Results The mean (median, range) pre-operative tumour thickness was 5.0 (5.12, 4.2–5.5) mm. The visual acuity ranged from 0.8–2.8 LogMAR and 3 of 4 eyes had only light perception at presentation. One eye had been treated with goniotomy for pre-existing secondary glaucoma and was on topical antihypertensive medications. At a mean follow up of 14.6 months (10.5 months, 6–30 months), all patients showed regression of the tumour. The mean tumour thickness reduced to 2.05mm (2.44mm, 1.1-2.6mm) post-operatively. Also, all patients (4/4) had complete resolution of the retinal detachment. The visual acuity remained stable in all the patients with none of the patients developing neovascular glaucoma or any other radiation related complications.Conclusion Ultrasound guided Ru 106 plaque brachytherapy is an effective treatment strategy as a primary treatment in the absence of external beam radiotherapy, to achieve tumour regression and resolution of retinal detachment in DCH.

Published: March 2024

In this study, low density silica nanoparticles (LDS) were produced utilizing the simplified stobber method with amino propyl tri ethoxy siliane (APTES) as an amine. The produced particles were calcined at 400°C to create low density particles. The produced particles were characterized using SEM, FTIR, DLS, and zeta potential analyses. The results confirmed that the particle size, charge, and density varied depending on the APTES concentration. The findings revealed that at lower APTES concentrations, small particles (70–75 nm) were formed, however at higher concentrations, larger particles (420–430 nm) were produced. The particle density varied according to APTES content; following calcination, the control sample had a density of 1.86 g/cm3, while the density of the APTES-added samples differed. UV absorption spectra showed substantial variations between 440 and 480 nm in APTES-added samples. Zeta potential tests showed that the greater concentration of APTES added sample was −10 mV, while the lower concentration was−26 mV. The catalytic activity was determined using crystal violet dye, and the kinetics were described. HRP-coated LDS was employed as a nanosensor to detect H2O2. Results showed linearity of 5×10−10  ~ 1×10−5 (M) (R2 = 0.995), and a detection limit of 5 nm mol. The milk was spiked with H2O2 in various concentrations and utilized as detections for the real sample analysis; the findings showed that the recovery rate was increased.

Methods A retrospective analysis was conducted on the clinical data of 592 patients with acute myocardial infarction who underwent PCI treatment. They were divided into a modeling group (414 cases) and a validation group (178 cases) in a ratio of 7:3.Define prolonged length of stay as hospitalization for more than 7 days after surgery.Single-factor and multi-factor logistic regression analysis were used to construct a predictive model and it was validated.
Results Female gender (OR = 5.72, 95%CI: 2.10-15.58), smoking(OR = 4.41, 95%CI:1.76–11.02), hypertension(OR = 2.32, 95%CI:1.27–4.24), hs-cTnT(OR = 1.12, 95%CI:1.02–1.26)and Killip functional classification were identified as independent factors associated with prolonged length of hospital stay after PCI in patients with acute myocardial infarction (P < 0.05).A column line graph predictive model was built using the aforementioned independent factors. The area under the curve (AUC) for predicting prolonged length of hospital stay after surgery was 0.852 for the modeling group and 0.831 for the validation group.The calibration curve of the predictive model showed good consistency in both groups.
Conclusion This model can effectively predict the risk of prolonged length of hospital stay after PCI in patients with acute myocardial infarction, providing a basis for clinical management and nursing guidance.

Purpose: Early identification of physical inactivity in children and adolescents using a simple reliable test like Incremental shuttle walk test (ISWT) can aid in prescription of evidence based early interventional programs to enhance cardiopulmonary exercise capacity.
Methods: Thousand participants recruited for study were stratified into 3 biological age groups-Group A: 5-8 years, Group B: 9-12 years and Group C: 13-17 years. Anthropometric measures were recorded and ISWT was performed as per standard protocol across a 10-meter shuttle walkway.
Results: Incremental shuttle walk distance was greater in males compared to females in all age groups(ISWD Group 1 females 395.36m, ISWD Group 2 females 492.16m,ISWD Group 3 females 582.22m (p= 0.00), ISWD Group 1 males 414.22m, ISWD Group 2 males 536.71m and ISWD Group 3 males 698.62m(p=0.00) ISWD demonstrated significant positive correlation with age (r=0.491, p=0.00) and weak negative correlation with gender (r-0.123,p=0.00).Stepwise linear regression analysis was performed to generate a predicative equation for ISWD with age and gender model ISWD (r2 = 0.611).
ISWD = 168.23 + (232.93*Height) - (86.47*Gender) + (11.42*Age) (Males 1, Females 0)
Conclusion: Reference values generated for ISWD can be used for prescription and regular monitoring of cardio pulmonary endurance of children and adolescents.

Background
Sheba Medical Center (SMC) is the largest hospital in Israel and has been coping with a steady increase in total Emergency Department (ED) visits. Over 140,000 patients arrive at the SMC's ED every year. Of those, 19% are admitted to the medical wards. Some are very short hospitalizations (one night or less). This puts a heavy burden on the medical wards. We aimed to identify the characteristics of short hospitalizations.
Methods
We retrospectively retrieved data of consecutive adult patients admitted to our hospital during January 1, 2013, to December 31, 2019. We limited the cohort to patients who were admitted to the medical wards. We divided the study group into those with short and those with non-short hospitalization.
Results
Out of 133,126 patients' admissions, 59,994 (45.0%) were hospitalized for short term. Patients in the short hospitalization group were younger and had fewer comorbidities. The highest rate of short hospitalization was recorded during night shifts (58.4%) and the rate of short hospitalization was associated with the ED daily patient load (r = 0.36, p < 0.001). The likelihood of having a short hospitalization was most prominent in patients with suicide attempt (80.0% of those admitted for this complaint had a short hospitalization), followed by hypertension (68.6%). However, these complaints accounted for only 0.7% of the total number of short hospitalizations. Cardiac and neurological complaints however, made up 27.4% of the short hospitalizations.
Conclusions
short hospitalizations in medical wards have special characteristics that may render them predictable. Lowering the ED load may decrease short hospitalizations. Referring patients with cardiac and neurological complains to short term units may decrease the rate of short hospitalizations in the medical wards and improve the care in these wards.
Reappraisal of the volcanic source of the widespread Rocourt Tephra in Belgium (78 – 80 ka)

The Rocourt Tephra (RT) is a widespread stratigraphic marker distributed in Germany, Belgium and the Netherlands, where it is used for stratigraphic correlations, dating of host sediments and of Middle Palaeolithic archaeological assemblages, sometimes including Neandertal remains. Its age is estimated between 78 and 80 ka. This tephra has been linked to the West Eifel Volcanic Field in Germany, but its corresponding source volcano is unknown. Such a discovery would make it possible to confirm or specify the age of the tephra, because this source volcano could be dated by various methods. It would also be possible to know the composition of the magma, which cannot be determined from the altered clasts of the tephra, as well as the original mineralogical composition, thereby strengthening the validity of the marker by providing more distinctive data. Two Eifel volcanoes have been cited as potential sources, the Dreiser Weiher and the Pulvermaar, based on their large sizes and broadly similar compositions. A study of the tephra layers derived from these two known volcanoes was carried out to compare their mineral compositions with that of the Rocourt Tephra. Neither of the two volcanoes can be the source of the RT.

Microorganisms like bacteria and fungi are crucial for host medicinal plant growth and development. However, environmental factors and host genotypes can influence microbiome composition and diversity in plants such as industrial hemp (Cannabis sativa L.), which can help us understand how they cope with climatic stresses and pathogenic attacks. We evaluated the endophytic and rhizosphere microbial communities of two cannabidiol (CBD; Sweet Sensi and Cherry Wine) and two fibers (American Victory and Unknown). The four hemp varieties showed significant variation in microbiome diversity. The roots had significantly abundant fungal and bacterial endophyte diversity indices, whereas the stem had higher fungal than bacterial diversity. Interestingly, the soil system showed no significant diversity variation across CBD vs. fiber genotypes. In fungal phyla, Ascomycota, Basidiomycota, and Mucuromycota were significantly more abundant in root and stem than leaves in CBD-rich genotypes compared to fiber-rich genotypes. The highly abundant bacterial phyla were Proteobacteria, Acidobacteria, and Actinobacteria. We found 16 and 11 core-microbiome bacterial and fungal species across genotypes, respectively. Sphingomonas, Pseudomonas, and Bacillus were the core bacterial microbiome of fiber genotypes with high abundance compared to CBD genotypes. Contrarily, Microbacterium, and Rhizobium were significantly higher in CBD than fiber. The Alternaria and Gibberella formed core-fungal microbiome of fiber-genotype than CBD. Contrarily, Penicillium, and Nigrospora were significantly more abundant in CBD than fiber genotypes. In conclusion, specific hemp genotypes recruit specialized microbial communities. Utilizing the core-microbiome species can help to maintain and improve the growth of hemp plants and to target specialized traits of the genotype.
