Background:
Preterm birth is the most significant factor for infant morbidity and mortality. Preterm infants are highly vulnerable to substantial comorbidities and need to be admitted to the neonatal intensive care unit (NICU). Prematurity and low birth weight (LBW) of infants, in particular, have been found to have a higher substantial burden on family resources and health-care resources after discharge from the hospital.

Objective:
To obtain data as a basis for strategic planning and efficient delivery of health-care resources, this study aims to determine the extent of health-care facility utilization among preterm infants during their first 2 years of life after discharge from the NICU.

Materials and Methods:
This was a retrospective cohort study design by reviewing the electronic medical records of preterm infants (i.e., <37 weeks' gestation) who were discharged from the NICU. Their outcomes were compared to healthy term infants. All examined infants were delivered at King Abdulaziz Medical City, Jeddah, Saudi Arabia, from June 1, 2016, to April 30, 2018.

Results:
In this single-center study, the NICU admission rate was 8.6%, and 4.18% of those were premature. In terms of facility utilization, preterm infants had a significantly higher frequency of outpatient visits, laboratory, and radiology performed as compared to healthy term infants. Preterm infants were also significantly and more likely to be admitted to the inpatient department. In subgroup analysis, very preterm, extremely preterm, low birth weight (LBW), very LBW (VLBW), and extremely LBW (ELBW) infants had higher outpatient visits and higher laboratory and radiology performed.

Conclusions:
Preterm infants utilized more health-care resources than healthy term infants. Very preterm, extremely preterm, VLBW, and ELBW infants had more outpatient visits and utilized the laboratory and radiology services more often than other subgroups. This study suggests developing an innovative strategic plan to effectively meet preterm infants' health-care needs, particularly by improving services in mostly utilized hospital resources.

Published: February 2021

Background:
Necrotizing enterocolitis (NEC) is the most common devastating acquired disease of the gastrointestinal tract in preterm infants.

Objective:
The study is aimed to evaluate maternal, infant risk factors, and radiological manifestation, in addition to the outcome.

Methodology:
This was a retrospective cohort study, all preterm infants born <32 weeks that were delivered in our tertiary care hospital from January 2011 to December 2018 with a confirmed diagnosis of NEC.

Results:
Forty-nine infants full-filled the inclusion criteria. The average weight of infants with NEC was 970 g (1028 ± 401) with P= 0.05. The gestational age of affected infants was 27.5 ± 2.9 weeks with P= 0.007, the average age of NEC diagnosis was 14.8 ± 11.2 days and their average length of stay was 79.9 ± 57.5 days with valueP = 0.015. Bowel stricture occurred in 4 (8.2%) infants with P < 0.001. Short bowel syndrome occurred in 1 (2%) infants with P < 0.001. Bronchopulmonary hypoplasia occurred in 24 (49%) with P < 0.001. Retinopathy of prematurity occurred in 9 (18.8%) with P < 0.001.

Conclusion:
Maternal parity multigravida had increased risk by more than double. More than half of our babies developed advanced NEC, which is double the reported figures found in other studies, which indicate routine needs to use of probiotics.

Published: February 2021

Context and Aim:
Formocresol has been used as the material of choice (gold standard) for pulpotomy procedures because of the ease of use but was discouraged due to its potential immune sensitization and mutagenic effects. Laser irradiation was first applied for pulpotomy procedure in the year 1985. Recently, diode lasers have been used for pulpotomy in primary teeth and have shown clinical success rates comparable to formocresol. The present in vivo study was carried out to compare the clinical and radiographic success rates of mineral trioxide aggregate (MTA) pulpotomy and diode laser-assisted pulpotomy in human primary molars.

Materials and Methods:
The present study was a randomized clinical trial in design wherein 40 primary teeth requiring pulpotomy treatment which met the selection criteria (clinical and radiographic) were divided into two groups, Group 1 (n = 20) wherein the pulpotomy was performed with MTA alone and Group 2 (n = 20) wherein laser-assisted pulpotomy was performed with MTA (L-MTA). The patients were recalled after 3, 6, and 9 months, respectively and evaluated clinically and radiographically.

Statistical Analysis Used:
The data were analyzed using the Statistical Package for the Social Sciences (SPSS) Version 22 (IBM corporation, Washington DC, United States). Descriptive statistics were used to analyze the data while the Pearson's correlation coefficient test was used to analyze the statistical correlation between the overall success rates observed in the clinical and radiographic findings of both the groups. P < 0.05 was considered statistically significant.

Results:
The clinical success rate in the MTA group was 90%, 84.21%, and 88.23% at 3, 6, and 9 months, respectively, with no clinical signs or, symptoms reported at the said follow-up visits while the radiographic success rate was found to be 85%, 84.21%, and 82.3%, respectively. On the contrary, the clinical success rate in the L-MTA group was found to be 95%, 94.74%, and 94.44% at 3, 6, and 9, months, respectively with the radiographic success rate reported being 90%, 89.47%, and 88.89%, respectively.

Conclusion:
The combination of diode laser and MTA yielded better clinical and radiographic success rates over the pulpotomy procedures done with the help of MTA alone, thereby, concluding that lasers may be considered as adjuvant alternatives for vital pulp therapy on human primary teeth.

AbstractFor a finite-dimensional Hopf algebra

$\mathsf {A}$
, the McKay matrix

$\mathsf {M}_{\mathsf {V}}$
of an

$\mathsf {A}$
-module

$\mathsf {V}$
encodes the relations for tensoring the simple

$\mathsf {A}$
-modules with

$\mathsf {V}$
. We prove results about the eigenvalues and the right and left (generalized) eigenvectors of

$\mathsf {M}_{\mathsf {V}}$
by relating them to characters. We show how the projective McKay matrix

$\mathsf {Q}_{\mathsf {V}}$
obtained by tensoring the projective indecomposable modules of

$\mathsf {A}$
with

$\mathsf {V}$
is related to the McKay matrix of the dual module of

$\mathsf {V}$
. We illustrate these results for the Drinfeld double

$\mathsf {D}_n$
of the Taft algebra by deriving expressions for the eigenvalues and eigenvectors of

$\mathsf {M}_{\mathsf {V}}$
and

$\mathsf {Q}_{\mathsf {V}}$
in terms of several kinds of Chebyshev polynomials. For the matrix

$\mathsf {N}_{\mathsf {V}}$
that encodes the fusion rules for tensoring

$\mathsf {V}$
with a basis of projective indecomposable

$\mathsf {D}_n$
-modules for the image of the Cartan map, we show that the eigenvalues and eigenvectors also have such Chebyshev expressions.

ABSTRACTRural communities from Latin America are particularly susceptible to develop serious outbreaks of infectious diseases. Inadequate diagnosis and poor health infrastructure jeopardize proper contact tracing and other actions to reduce the impact of COVID-19 in the region. We herein describe the preliminary data of our ongoing fieldwork of massive testing among nonhospitalized rural population in Manabi Province of the coastal region of Ecuador. A total of 1,479 people from six different rural communities were tested for SARS-CoV-2 by RT-qPCR following the CDC protocol; 350 individuals tested positive, resulting in an overall attack rate of 23.7% for SARS-CoV-2 infection. This ultrahigh prevalence must urge to the public health authorities from Ecuador to take immediate actions to counteract this dramatic scenario in Manabi Province and to improve SARS-CoV-2 testing countrywide.

Cette étude a permis de déterminer la distribution et les habitats potentiels de Newbouldia laevis et de Dracaena arborea dans les zones bioclimatiques du Bénin en vue de leur gestion durable. Trente relevés phytosociologiques ont été effectués dans les formations végétales. La matrice obtenue a permis de discriminer les forêts sacrées (74 genres ; 46 familles ; Richesse spécifique=130 ; H=5,92 bits; R=0,97) des champs/jachères (42 genres ; 28 familles ; Richesse spécifique =69; H=3,40 bits; R=0,62). Les densités moyennes de tiges sont passées en forêts sacrées de 64 à 31 et à 0 tiges.ha-1; puis de 28 à 16 tiges.ha-1 dans les champs/jachères chez D. arborea. Chez N. laevis, ces densités sont passées de 30 à 15 puis à 09 tiges.ha-1 en forêts sacrées et de 89 à 56 et à 13 tiges.ha-1 dans les champs/jachères respectivement en zones guinéo-congolaise, soudano-guinéenne et soudanienne. Les phanérophytes et les espèces guinéo-congolaises sont les plus dominants. D. arborea et N. laevis se conservent mieux respectivement en forêts sacrées et en champs/jachères. Leur introduction dans les programmes de reboisement et la protection de leurs habitats potentiels seraient un atout pour leur meilleure conservation et contribueront à formuler des recommandations soutenues pour leur valorisation au Bénin.Mots clés : Bénin, Distribution, Zones bioclimatiques, Newbouldia laevis, Dracaena arborea.

English Title: Distribution and habitats of Newbouldia laevis (P.Beauv.) Seemann ex Bureau and Dracaena arborea (Willd.) Link in the bioclimatic zones of BeninThis study carried out in the three bioclimatic zones of Benin aims to determine the potential habitats and the geographic distributions of Newbouldia laevis and Dracaena arborea, two anthropophilic agroforestry species in order to conserve them sustainably. Thirty phytosociological surveys were sampled and the matrix gotten was subjected to an analysis of the adjusted correspondences (DCA) to discriminate the sacred forests with great diversity (Rf = 130; H = 5.92; R = 0.97) of the fields/fallows of medium diversity (Rf = 69; H = 3.40; R = 0.62) and balanced. The average densities of stems went from 64, 31 and 0 stems.ha-1 in D. arborea to 30, 15 and 09 stems.ha-1 in N. laevis in sacred forests and in fields/fallows from 28, 16 and 0 stems.ha-1 in D. arborea at 89, 56 and 13 stems.ha-1 in N. laevis respectively in guinean-congolese, sudano-guinean and sudanian zones. Phanerophytes constitute 85% of the average recovery in number and occupation of space. Guinean-congolese species are dominant and have a wide distribution spectrum. D. arborea and N. laevis keep better in sacred forests and fields / fallows respectively. The protection of potential habitats and the introduction of species into national reforestation programs as a priority would be an asset for better conservation.Keywords : Benin, Distribution, bioclimatic zone, Newbouldia laevis, Dracaena arborea.
Crepant resolutions and open strings II
Authors: Brini Andrea , Cavalieri Renzo 
Published: February 2021

We recently formulated a number of Crepant Resolution Conjectures (CRC) for open Gromov-Witten invariants of Aganagic-Vafa Lagrangian branes and verified them for the family of threefold type A-singularities. In this paper we enlarge the body of evidence in favor of our open CRCs, along two different strands. In one direction, we consider non-hard Lefschetz targets and verify the disk CRC for local weighted projective planes. In the other, we complete the proof of the quantized (all-genus) open CRC for hard Lefschetz toric Calabi-Yau three dimensional representations by a detailed study of the G-Hilb resolution of $[C^3/G]$ for $G=\mathbb{Z}_2 \times \mathbb{Z}_2$. Our results have implications for closed-string CRCs of Coates-Iritani-Tseng, Iritani, and Ruan for this class of examples.Comment: v2: typos fixed, minor changes. v3: some minor points have been clarified, further typos fixed. v4: version accepted for publication on EPIGA
Troisi\`eme groupe de cohomologie non ramifi\'ee d'un solide cubique sur un corps de fonctions d'une variable
Authors: Colliot-Thélène Jean-Louis , Pirutka Alena 
Published: February 2021

En combinant une m\'ethode de C. Voisin avec la descente galoisienne sur le groupe de Chow en codimension $2$, nous montrons que le troisi\`eme groupe de cohomologie non ramifi\'ee d'un solide cubique lisse d\'efini sur le corps des fonctions d'une courbe complexe est nul. Ceci implique que la conjecture de Hodge enti\`ere pour les classes de degr\'e 4 vaut pour les vari\'et\'es projectives et lisses de dimension 4 fibr\'ees en solides cubiques au-dessus d'une courbe, sans restriction sur les fibres singuli\`eres. --------------- We prove that the third unramified cohomology group of a smooth cubic threefold over the function field of a complex curve vanishes. For this, we combine a method of C. Voisin with Galois descent on the codimension $2$ Chow group. As a corollary, we show that the integral Hodge conjecture holds for degree $4$ classes on smooth projective fourfolds equipped with a fibration over a curve, the generic fibre of which is a smooth cubic threefold, with arbitrary singularities on the special fibres.Comment: in French

Rigidity properties of holomorphic Legendrian singularities
Authors: Hwang Jun-Muk 
Published: February 2021

We study the singularities of Legendrian subvarieties of contact manifolds in the complex-analytic category and prove two rigidity results. The first one is that Legendrian singularities with reduced tangent cones are contactomorphically biholomorphic to their tangent cones. This result is partly motivated by a problem on Fano contact manifolds. The second result is the deformation-rigidity of normal Legendrian singularities, meaning that any holomorphic family of normal Legendrian singularities is trivial, up to contactomorphic biholomorphisms of germs. Both results are proved by exploiting the relation between infinitesimal contactomorphisms and holomorphic sections of the natural line bundle on the contact manifold.Comment: 21 pages, minor revision
Free Proalgebraic Groups

Replacing finite groups by linear algebraic groups, we study an algebraic-geometric counterpart of the theory of free profinite groups. In particular, we introduce free proalgebraic groups and characterize them in terms of embedding problems. The main motivation for this endeavor is a differential analog of a conjecture of Shafarevic.Comment: 36 pages, final accepted version

Media Iklan yang Ramah Wisatawan Milenial
Authors: Hakim Imam nur 
Published: February 2021

Millennials grow massively. Their immense purchasing power also supports it. So, many sectors in the world make it a market opportunity. This leap is also done by the tourism sector, especially in Indonesia. The generation referred to as the-next-future-tourist has different characteristics in travelling compared to the previous generation. As a result, there are differences in the choice of promotional media that are friendly to millennial tourists. DMO needs to take a different approach and can no longer use conventional media choices to promote. Through a descriptive qualitative approach, this study will use a literature study pattern to link millennial tourist preferences with the right choice of media in the promotion. This study found that social media, influencer's role, email marketing, website, review site, and search engines became â€œfriendlyâ€ media to promote to millennial tourists.

Published: February 2021

Cross-border posts have a big role in contributing foreign tourists to Indonesia, but until now the records carried out are still less optimal. This study aims to identify the potential for tourist visits through the Builaloâ€™s Cross-border Post, so that the development of tourism that depends on this post can be further optimized. By using descriptive methods where data is collected through documentation studies, field observations, and interviews. This research has successfully identified that the Builalo Cross-border Post located in East Nusa Tenggara Province has the potential for foreign tourists to visit an average of 5.55 per day or 2,026 foreign tourists per year. Foreign tourist visits through this gate are strongly influenced by the Market Day which is held every Thursday, where that day always has the highest peak visit in 1 week, and it is estimated that the average visit on that day is 23.7. foreign tourist visits. Inadequate facilities and infrastructure are the most serious challenges in the development of Tourism in the area adjacent to this gate. Because visiting friends or relatives is another main goal besides visiting market days, it creates more economic activity (trade, festivals, etc.) and an increase in supporting facilities is felt very necessary.
