High Voter Participation during the Pandemic Covid-19 (Public Communication Success or Mass Mobilization of Single Candidates)
Authors: Roso Prajoko  , Sri Hartini  , Nurdini Tsabitul Chusna
Published: July 2023

Politics in Boyolali Regency is controlled by the PDI-P with control of 35 seats for DPRD members in parliament, followed by the Golkar Party with 4 chairs, PKS with 3 chairs, PKB with 2 chairs and the Gerindra Party with 1 seat. With the majority of the number of DPRD members in parliament, PDI P rallied with all parties that won seats in parliament to nominate the incumbent as the sole regent candidate, except for the Prosperous Justice Party (PKS) which was neutral. Although only one pair of candidates participated, and it was carried out during the Covid-19 outbreak, the voter turnout rate in Boyolali was very high. This researcher will see, if the high participation is due to the success of political communication between the candidates and the KPU or whether there is a mass mobilization movement from the candidate for regent. This study uses a descriptive qualitative approach. The results of the election of a single candidate against an empty box are unattractive because there is no competition or power struggle. Even though it wasn't interesting, people still came to the polling station due to massive socialization from the Boyolali KPU.
Jurnalisme Advokasi pada Project Multatuli dalam Isu Ibu Kota Negara (IKN) Nusantara
Authors: Alwaton Yogie Alwaton
Published: July 2023

Penelitian ini berangkat dari premis bahwa suara masyarakat yang terpinggirkan sangat jarang tersentuh oleh media. Penelitian ini bertujuan untuk menganalisis penerapan jurnalisme advokasi pada Project Multatuli dalam isu Ibu Kota Negara (IKN) Nusantara. Banyak pihak yang masih tidak setuju dengan pemindahan ibukota ini. Terkait ini, media sudah banyak yang meliput isu IKN. Namun, kebanyakan media tidak banyak meliput mengenai dampak yang dirasakan langsung oleh warga setempat dengan adanya pemindahan IKN ini ke wilayah mereka. Padahal, penolakan justru banyak pula dilontarkan oleh warga Penajam Paser Utara. Namun tak ayal pemberitaan mainstream tanah air justru didominasi oleh perspektif elit dan tidak memerhatikan perspektif warga yang tidak mampu bersuara. Sehingga, disinilah peran dari jurnalisme advokasi. Jurnalisme advokasi adalah salah satu genre dalam jurnalisme yang berfokus pada suara-suara kelompok marjinal yang jarang terekspos oleh media. Dengan menggunakan metode analisis isi kualitatif melalui satu judul artikel Project Multatuli, diperoleh hasil bahwa jurnalisme advokasi pada media alternatif ini sudah diterapkan dengan baik. Kelima unsur jurnalisme diterapkan pada artikel liputan yang ada. Peneliti hanya menemukan satu unsur yang luput dalam jurnalisme advokasi ini, yakni terkait asas legalitas. Namun, tegasnya, Project Multatuli telah melakukan bentuk jurnalisme advokasinya yang sesuai dengan semangatnya untuk mengangkat suara-suara terpinggirkan dan masyarakat kecil.

Indonesian education continues to develop to produce a competitive and morally upright generation. As a process, the administration of Kurikulum Merdeka continues to be developed with an independent learning curriculum as its guiding principle. In addition, it is anticipated that learning will be student-centered by prioritizing children's overall growth and development and by encouraging teachers to always be student-centered. This research seeks to collect field-based information on the implementation of Kurikulum Merdeka in Islamic senior high schools. The descriptive qualitative method with Rogers' theory of diffusion innovation was used, and data analysis was conducted through interviews and direct observations with the school dean and 27 instructors. The findings of this study indicate that the Kurikulum Merdeka not only offers new learning experiences to teachers but is also capable of unifying divisions in the learning process with results derived from both the innovation attribute and innovation development process. The subsequent research is an evaluation of the curriculum that has been implemented in Senior High Schools or Islamic Senior High Schools.Keywords: Islamic Education; Kurikulum Merdeka; Integrated Islamic School

Published: July 2023

This study seeks to identify alternative learning models to increase children's creativity in CIBI student service program schools. The approach utilized is a combined research method consisting of a qualitative research pattern and an exploratory research design. The research procedure consisted of two phases; the first phase entailed analyzing problems and potentials in the world of education, particularly in the CIBI student service program in West Java; the second phase involved drafting a learning model in the scaffolding model. For the second stage, the results of scaffolding model formulation in the field were being piloted as a limited test related to creativity. Calculating t-test (0.025) for a two-tailed test on the student distribution (t) dk = 37 yielded ttab = -2,026, indicating that the use of scaffolding increased the frequency distribution of creativity among students with strong academic credentials. The calculation hit = -5.32 is in the Ho rejection area, and statistical analysis using the t-test indicates that the model is quite effective in increasing creativity in learning at CIBI student service programs. This indicates that the discovered model can positively influence the creative development of children.Keywords: Constructivism; Creativity Scaffolding Model; Educational Management

Published: July 2023

En esta investigación se evaluó la importancia que tienen las arvenses en el sostenimiento de la diversidad de insectos que visitan las flores de café. Se seleccionaron dos parcelas con manejo integrado de arvenses (MIA) y dos con manejo excesivo (MEA). En cada parcela se recolectaron y registraron los insectos visitantes de las flores de café en 30 árboles, en intervalos de ocho minutos por árbol, en tres horarios durante un día. Los muestreos se realizaron en dos eventos de floración por año, durante dos años, para un total de 192 horas de observaciones. Por parcela se identificaron los insectos y se estimaron abundancia, riqueza y diversidad del orden q=1 y q=2. Estos valores fueron comparados mediante una prueba de diferencia mínima significativa al 5%. En las parcelas MIA se trazaron tres transectos y se recolectaron los insectos visitantes de las arvenses, con igual frecuencia y forma que en el muestreo anterior, durante los períodos sin floración del café. En las flores del café de las parcelas MIA se registraron 2.347 individuos y 163 especies, en las parcelas MEA se recolectaron 2.543 individuos y 162 especies; en las arvenses se registraron 735 individuos y 171 especies. La riqueza, abundancia y valores de diversidad del orden q=1 y q=2 fueron estadísticamente iguales entre las parcelas. Las arvenses Bidens pilosa, Commelina difusa, Emilia sonchifolia, Hyptis atrorubens y Galinsoga parviflora, fueron las más visitadas por los insectos. Los resultados muestran una alta diversidad de especies de insectos visitantes florales, tanto en el cultivo del café como en las arvenses.

Authors: Rendón José Raúl , Grajales Angela María , Salazar Hugo Mauricio
Published: July 2023

La raíz del café cumple funciones de soporte, absorción de agua y nutrimentos necesarios para el crecimiento y la producción. Con el objetivo de evaluar la biomasa de raíces de café en diferentes tipos de renovación, se tomaron muestras cada tres meses, durante un año, en 30 árboles seleccionados de forma aleatoria por cada evaluación. Las muestras de suelo y raíces fueron extraídas a 25 y 50 cm de distancia horizontal, desde la base del tallo, en los primeros 20 cm desde la superficie. Se seleccionaron aquellas raíces con diámetro inferior o igual a 3 mm y se clasificaron en vivas o muertas. Para zoca común, poda pulmón y poda calavera1, se encontraron diferencias significativas en la cantidad de biomasa de raíces vivas, tanto a 25 cm como a 50 cm, al comparar los promedios de la fecha inicial y después de la renovación, similar respuesta se encontró al analizar la composición de raíces totales (vivas y muertas). La mayor eliminación de tejido aéreo en las plantas renovadas condujo a la disminución de la biomasa de raíces en el primer año, no obstante, el desarrollo de nuevas raíces se observó a medida que las plantas aumentaron la edad, recuperando hasta un 74% de la biomasa inicial en árboles de zoca común de dos años. De forma complementaria la producción de café en un período de cinco años, presentó para la zoca común un valor acumulado de 50.865 kg de café cereza, superior al registrado con los otros tipos de renovación.

We report on a detailed abundance study of six bright, mostly southern, slowly rotating late B-stars: HD 1279 (B8III), HD 99803 (B9V), HD 123445 (B9V), HD 147550 (B9V), HD 171961 (B8III), and HD 202671 (B5II/III), hitherto reported as normal stars. We compare them to the two classical HgMn stars μ Lep and β Scl, and to the superficially normal star ν Cap. In the spectra of the six stars, the Hg ii line at 3984 Å line is clearly seen and numerous lines of P, Ti, Mn, Fe, Ga, Sr, Y, and Zr appear to be strong absorbers. A comparison of newly acquired and archival spectra of these objects with a grid of synthetic spectra for selected unblended lines reveals large overabundances of P, Ti, Cr, Mn, Sr, Y, Zr, Ba, Pt, and Hg, and underabundances of He, Mg, Sc, and Ni. The effective temperatures, surface gravities, low projected rotational velocities, and the peculiar abundance patterns of the six investigated stars show that they are new chemically peculiar stars, mostly new HgMn stars, and are reclassified as such. The evolutionary status of these stars has been inferred, and their ages and masses estimated. The two most massive objects, HD 1279 and HD 202671, might have evolved away from the main sequence recently, the other stars are main-sequence objects. HD 99803A is a sharp lined HgMn star with grazing eclipses. From TESS and MASCARA photometry, we determine an orbital period of P
orb = 26.12022 ± 0.00004 day.
An Observed Transition of Galaxy Spins on Void Surfaces
Authors: Lee Jounghun , Moon Jun-Sung
Published: July 2023

In linear theory, the galaxy angular momentum vectors that originate from initial tidal interactions with surrounding matter distribution intrinsically develop perpendicular alignments with the directions of maximum matter compression, regardless of galaxy mass. In simulations, however, galaxy spins exhibit parallel alignments in the mass range lower than a certain threshold, which depends on redshift, web type, and background cosmology. We show that the observed three-dimensional spins of the spiral galaxies located on the void surfaces from the Sloan Digital Sky Survey indeed transit from perpendicular to parallel alignments with the directions toward the nearest void centers at the threshold zone,

Luminosity Outburst of a High-mass Young Stellar Object Triggered by the Surrounding Radiation Field
Authors: Liu Jun-Ting , Chen Xi , Chen Xiao-Dian , Chen Zhi-Wei , Song Shi-Min , Wang You-Xin , Zhang Yan-Kun , Zhao Zhang , Li Bin , Xia Bo , Shen Zhi-Qiang
Published: July 2023

We present observations of the 6.7 GHz methanol and 4.8 GHz formaldehyde masers toward the high-mass young stellar object G24.33+0.14 (hereafter G24). Our observations were conducted from 2019 to 2021 using the Shanghai Tianma 65 m Radio Telescope and the Very Large Array in response to the luminosity outburst event traced by these two species masers in 2019. Our results indicate that the provenance of the maser flares is unlikely to be ascribed to the protostar of G24 itself. Through analyzing NEOWISE infrared monitoring data, we identified two light curves of G24 with long-term (3083 days, ∼8.5 yr) and short-term (424 days) periods. Intriguingly, 11 periodic variable sources located in the same bubble as G24 exhibiting periods comparable to the short-term period of G24 were also detected. The analysis of the spectral energy distributions of these periodic variables revealed a possible correlation between their temperature fluctuations and the surrounding radiation field that possibly emanates from the driving source of the bubble. This source could be an individual supergiant protostar of a few hundred solar masses with periodic pulsation potentially accounting for the observed short-term period in the G24 region.

Modeling the Free Inclinations of the Classical Kuiper Belt with the von Mises–Fisher Distribution
Authors: Malhotra Renu , Roy Supriya
Published: July 2023

The orientations of orbital planes of minor planets are directional random variables. Their free inclination is the deviation of the orbit plane from the plane forced by the major planets. We construct a model of the distribution of free inclinations of classical Kuiper Belt objects (CKBOs) based on the von Mises–Fisher (vMF) distribution function, the analog of the normal distribution for directional statistics. The CKBOs are known to have a “cold” component of orbit planes concentrated near the forced plane and a more widely dispersed “hot” component. Adopting a model with a linear combination of two vMF functions, we find that the cold and hot components account for 57% and 43%, characterized by widths of 1.°7 and 12.°9, respectively. This model improves upon previous models based on smaller observational samples and empirical choices of functional forms for inclination distributions.

Technological strategies for the preparation of lipid nanoparticles: an updated review
Authors: Stefanov Stefan , Gugleva Viliana , Andonova Velichka
Published: July 2023

The concept of improving drug biopharmaceutical properties by proper selection of delivery system should begin with a rational choice of relevant dosage form, followed by the precise assessment of physicochemical compatibility between the drug delivery system (DDS) and the active pharmaceutical ingredient (API). Afterwards, according to laboratory availabilities, an efficient production method should be selected and, if possible, to take into account the opportunity for lab-upscale and prevailed industry research needs. Amid the vast diversity of nanostructured drug delivery carriers, lipid nanoparticles (LNs) stand out with their undeniable advantages like exceptive biocompatibility and multiplicity, and their importance as “green” derivatives for biochemical processes. Their distinctive structural properties also allow adequate protection of loaded APIs against chemical degradation in an aggressive biological environment and provide excellent resiliency in modifying drug release profiles. This review highlights different findings reported by the researchers worldwide over the years and focuses on the various production strategies and techniques for the preparation of LNs.
Rosa davurica var. ﻿rubro-stipulata (Rosaceae), the correct name for ﻿R. davurica var. ﻿﻿alpestris
Authors: Kim Young-Soo , Son Dong Chan
Published: July 2023

The name Rosa davurica var. alpestris (Nakai) Kitag. was published in 1979 as a new combination based on R. rubro-stipullata var. alpestris Nakai. It is generally accepted as a deciduous shrub occurring in Russia, Manchuria, Japan, and the northern part of the Korean Peninsula and is distinguished by the presence of eglandular leaves. Rosa rubro-stipullata var. alpestris was originally described as a new variety with a leaf size relatively smaller than that of R. rubro-stipullata var. rubro-stipullata . However, the observation of various specimens showed the leaf size of var. alpestris to be of minor importance, and it was included in var. rubro-stipullata as a synonym. Due to the priority of autonyms, a new combination is required to replace R. davurica var. alpestris. Additionally, it should be noted that the epithet “rubro-stipullata” is derived from the Latin word “stipula” rather than “stipulla.” Therefore, for this variety, we propose a new combination, R. davurica var. rubro-stipulata (Nakai) D. C. Son & Y. S. Kim, comb. nov. & stat. nov.

Published: July 2023

In this paper, the multiple constraint least squares solution of the Sylvester equation $ AX+XB = C $ is discussed. The necessary and sufficient conditions for the existence of solutions to the considered matrix equation are given. Noting that the alternating direction method of multipliers (ADMM) is a one-step iterative method, a multi-step alternating direction method of multipliers (MSADMM) to solve the considered matrix equation is proposed and some convergence results of the proposed algorithm are proved. Problems that should be studied in the near future are listed. Numerical comparisons between MSADMM, ADMM and ADMM with Anderson acceleration (ACADMM) are included.
Ibn ʿAbd al-Barr y los anwāʾ: astronomía y religión en al-Andalus
Authors: Forcada Miquel
Published: July 2023

Ibn ʿAbd al-Barr (368/978-463/1071), uno de los mayores ulemas andalusíes del siglo V/XI, incluye un largo capítulo sobre los anwāʾ en su Kitāb al-Tamhīd, que se estudia, junto a textos afines, en sus dos aspectos fundamentales. En el plano literario, el capítulo contiene una especie de tratado de anwāʾ abreviado que constituye uno de los raros ejemplos de textos andalusíes relacionados con este género en la época de los taifas. En el plano religioso, el capítulo expresa un debate sobre la licitud de los anwāʾ centrado en el hadiz transmitido por Ṣāliḥ ibn Kaysān que condena los anwāʾ en tanto que creencia preislámica. Por su tratamiento extenso y profundo del tema, el capítulo del Tamhīd es uno de los documentos que aporta un mayor conocimiento sobre el problema de fondo del sistema de los anwāʾ y la literatura derivada: su licitud teniendo en cuenta que se basa en una creencia pagana. El debate adquiere todo su sentido cuando se sitúa en una discusión más amplia, frecuente en el s. V/XI andalusi: el uso correcto de la astronomía, ya sea la astronomía matemática de origen griego o la astronomía popular árabe vinculada a los anwāʾ, en un contexto religioso, teniendo en cuenta la oposición a la astrología, considerada generalmente por los ulemas como una disciplina ilícita.
High-Stakes Online Exams
Authors: MacKevett Douglas , Gutmann Martin
Published: July 2023

COVID-19 has affected university assessment procedures on a large scale. This empirical study aims to understand the types of high-stakes exams delivered online at the Lucerne School of Business in Switzerland during the “Corona Semesters” of 2020 and 2021 and the decision-making factors that influenced their implementation. To do so, the authors conducted semi-structured interviews with eight faculty members across a variety of disciplines. Requirements from the exam workflow (preparation, proctoring, grading) were identified and analyzed by course type. Four factors emerged that significantly impacted design and delivery for high-stakes exams online: 1) Digital exam formats significantly impact the nature of exams for procedural subjects such as mathematics; 2) “Group Exams” are not the answer to preventing student collusion on online exams; 3) interrater reliability and low answer variance are considered a central factor for exam quality assurance; 4) second-order effects such as stable wifi and device compatibility will continue to hinder widescale adoption of digital exams. The findings suggest that online exam delivery significantly affects institutional exam practice beyond mere consideration of learning outcomes. The authors conclude by speculating that similar dynamics may have impacted other business schools during their Corona semesters and invite future research on whether the findings from this article can spark discussion and reflection for policy makers in other institutions on post-pandemic legacies.

It is recommended to use different resources to overcome university teachers’ stress.
University Students’ Perceptions of Google Tools in Learning English Courses Online
Authors: Pham Duc Thuan , Nguyen Thi Hong Hanh
Published: July 2023

The disruptions caused by the COVID-19 pandemic stimulated the utility of the technological tools for online language learning at the tertiary level in Vietnam. Many universities chose Google digital tools as a technological solution for online instruction. However, there is still a scarcity of studies on university students’ perceptions of using Google tools in the context of online English learning. This study aims to explore university students’ perceptions of the efficacy of using Google tools (namely, Google Classroom, Google Forms, Google Meet, and Google Sites) as a combined technological solution for online English learning in the last phase of the pandemic at a university in northern Vietnam. The research was carried out in the academic year 2021–2022, with 128 non-English majors taking General English courses online. A Likert-scale questionnaire created by Google Forms was distributed to gather feedback from the students, and semi-structured interviews were conducted with eleven students to gain more in-depth data. The results overall demonstrated that the students favorably perceived the applied Google tools as effective tools to support online English learning. It was also found that females had higher perceptions than males regarding the ease of the tools. Furthermore, first-year students agreed more than second-year students on the effectiveness of the tools in increasing engagement in learning.

Published: July 2023

The paper presents the analysis of strategies and challenges of technology-enhanced personalized language learning at technical universities. The authors specify the meaning of the “personalization” concept in terms of language learning and characteristics of technologyenhanced learning. Skills of personalized learning contribute to the development of learner autonomy and equip students with flexibility and adaptability to the changing demands of today’s labor market. The empirical study was carried out among 101 students from two universities. The questionnaire was aimed at measuring the level of personalized learning skills and digital resources that promote the personalized learning. Students were suggested three questionnaires: one survey on personalized learning skills was performed before and after the experiment, reflection questionnaire and on digital resources ranking were suggested after the experiment. After the introduction of technology-enhanced personalized learning strategies into the educational process, the level of personalized learning skills increased as well as students’ perception of this educational phenomena. There was no significant difference between the results of students from different universities in terms of personalized learning skills. It means that the problem of personalized learning is relevant to the majority of students and requires solutions. The paper provides examples of digital resources’ practical application that intensify the personalization with a promising transition to selfimprovement and successful professional self-realization.
Metaheuristics: A Review of Algorithms
Authors: Sadeeq Haval Tariq , Abdulazeez Adnan Mohsin
Published: July 2023

In science and engineering, many optimization tasks are difficult to solve, and the core concern these days is to apply metaheuristic (MH) algorithms to solve them. Metaheuristics have gained significant attention in recent years, with nature serving as the fundamental inspiration where self-organization property led to collective intelligence emerging from the behavior of a swarm of birds or colony of insects or more and more natural behavior. These swarms or colonies, even with extremely low individual competence, have the ability to accomplish many complicated activities that can be considered necessary for their existence. Accordingly, many MH algorithms have been developed based on natural phenomena. In this article, an analysis review of more than one hundred metaheuristics have been made. Further, the main contributions of this article are to give some vital insights about metaheuristics, presenting and proposing the general mathematical framework of MH algorithms and dividing it into a number of tasks with possible progress for each task. While there are still many open issues in this field, it is worth noting that there have been significant advancements in recent years. As a result, new algorithms are continuously being proposed to address these challenges.

Incidence and Severity of Virus Diseases of Cowpea (Vigna unguiculata L. Walp) Under Varying Planting Density and Insecticidal Spray Regimes
Authors: Alaka S. A. , Balogun O. S.
Published: July 2023

Viral diseases are a major problem for cowpea production in Nigeria, causing yield reductions of up to 100%. To combat this, farmers use insecticide sprays and manipulate plant population densities. A field experiment was conducted in the Southern Guinea Savannah agro-ecological zone of Nigeria in 2016 cropping season to assess the impact of planting density and insecticidal spray regimes on virus diseases in cowpea. The study found that the lowest disease incidence (32.2%) was observed at a density of 25×75 cm, and the highest (41.9%) at a density of 75×75 cm. The combination of a density of 25×7 5cm with three insecticidal spray regimes had the lowest incidence (18.6%), while 75×75 cm with no insecticidal spray had the highest (66.5%) disease incidence. Thus, it is recommended to use a planting density of 25×75 cm with three insecticidal spray regimes. This study emphasizes the importance of planting density and insecticidal spray regimes in managing viral diseases in cowpea production. Farmers can utilize this information to reduce disease incidence and severity and increase yield.

Exploring the oceans for bioactive compounds is an incessant human desire. The present study investigates selected bioactivities; anti-inflammatory, anti-oxidant, cytotoxic, and genotoxic potential of Axinella sp. marine sponge crude extract (SCE). Sponge identification was based on morphology and skeletal analysis. The SCE was prepared by methanol/dichloromethane extraction and tested for zoo-chemicals, anti-inflammatory properties by protein denaturation, heat and hypertonicity-induced bovine erythrocyte membrane stability assays. Radical scavenging activity was tested against 2,2-diphenyl-1-picryl-hydrazil (DPPH), 2,2′-Azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), nitric oxide (NO), and peroxide radicals. The IC50 was calculated for each assay. Cytotoxicity and genotoxicity were tested on Artemia salina and Allium cepa models, respectively. The LC50 and mitotic index (MI) were calculated where appropriate, while chromosomal aberrations were recorded in the A. cepa assay. The results indicated the presence of alkaloids, terpenoids, unsaturated sterols, flavonoids, and saponins in SCE. Potent inhibitory activities on egg albumin denaturation were reported by SCE (IC50=39.55±3.21 μg/ml). Heat and hypertonicity induced bovine erythrocyte membrane stability was reported as IC50=44.64±0.56 μg/ml and IC50=35.7±.0.26 μg/ml, respectively. In comparison to reference drugs, the resulting scavenging activities were strong against NO (IC50=50.63±2.85 μg/ml) and more or less similar against DPPH (IC50=42.49±0.85 μg/ml). However, the potency of ABTS and peroxide radical scavenging activities was low in SCE (IC50=42.49±0.74 μg/ml and IC50=323.52±3.71 μg/ml, respectively). The SCE was toxic to A. salina nauplii (LC50=106.81 μg/ml) and A. cepa root cells (LC50=114.63 μg/ml) with a 7.2% chromosomal aberrations reported in the A. cepa genotoxicity assay. The potent anti-inflammatory, anti-oxidant, cytotoxic, and genotoxic effects of SCE proposes its feasibility as a potential drug lead, followed by further comprehensive research.

Published: July 2023

Background:

Transthoracic echocardiography is a very helpful noninvasive cardiovascular imaging technique for the diagnosis and risk stratification in the management of patients with cardiovascular diseases. We aimed to review the clinical indications for transthoracic echocardiography and the confirmation rate of cardiovascular diseases by echocardiography at a specialist cardiac clinic in Ghana.

Methods:

Using a cross-sectional study design, the echocardiography reports of all patients above the age of 15 who were assessed at the clinic were analyzed. Data on patient demographics, clinical history, clinical indication for echocardiography, and the echocardiographic findings were analyzed using version 25.0 of the Statistical Package for Social Sciences (SPSS).

Results:

A total of 594 participants were studied. The age range of participants was 15–96 years, with a mean (± standard deviation) age of 53.72 (± 17.25) years. There were more females (50.17%) than males (49.83%). Most (54.21%) of the participants had echocardiography for cardiac evaluation. Other indications included hypertension/hypertensive heart disease (HHD) (n = 131; 22.06%), heart failure (n = 69; 11.62%), chest pains (n = 12; 2.02%), and valvular heart disease (VHD) (n = 11; 1.85%). Three hundred and eight-nine (70.30%) of the participants had their clinical diagnoses confirmed by echocardiography; echocardiographic confirmation rates for heart failure, VHD, and HHD were 92.75%, 90.91%, and 88.54%, respectively.

Conclusion:

Echocardiography showed high confirmation rates for our patients with heart failure, VHD, and HHD. Prompt usage of this noninvasive cardiovascular imaging for the initial evaluation of patients with cardiovascular diseases is highly recommended.

Context:

Newborns' low birth weight (LBW) has been linked to early infant morbidity and mortality. However, our understanding of the determinants and outcomes of LBW in this population is still poor.

Aim:

This study aimed to assess determinants and outcomes of LBW among newborns at a tertiary hospital.

Settings and Design:

Retrospective cohort study at Women and Newborn Hospital in Lusaka Zambia.

Subjects and Methods:

We reviewed delivery case records and neonatal files between January 1, 2018, and September 30, 2019, for newborns admitted to the neonatal intensive care unit.

Statistical Analysis Used:

Logistic regression models were used to establish determinants of LBW and describe the outcomes.

Results:

Women living with human immunodeficiency virus infection were more likely to deliver LBW infants (adjusted odds ratio [AOR] = 1.46; 95% confidence interval [CI]: 1.16–1.86). Other maternal determinants of LBW were; increased parity (AOR = 1.22; 95% CI: 1.05–1.43), preeclampsia (AOR = 6.91; 95% CI: 1.48–32.36), and gestational age <37 weeks compared to 37 weeks or more (AOR = 24.83; 95% CI: 13.27–46.44). LBW neonates were at higher odds of early mortality (AOR = 2.16; 95% CI: 1.85–2.52), developing respiratory distress syndrome (AOR = 2.96; 95% CI: 2.53–3.47), and necrotizing enterocolitis (AOR = 1.66; 95% CI: 1.16–2.38) than neonates with a birth weight of 2500 g or more.

Conclusions:

These findings underscore the importance of effective maternal and neonatal interventions to reduce the risk of morbidity and mortality for neonates with LBW in Zambia and other similar settings.

Emphysematous pancreatitis (EP) is a rare and potentially fatal condition of the pancreas. It is associated with gas-forming bacteria and is characterized by the presence of gas in or around the pancreas. It is identified by a computed tomography scan of the abdomen. Although predisposing factors are not precisely known, diabetes mellitus, which predisposes to gas gangrene, is seen to be commonly associated with patients of EP. EP being potentially fatal requires immediate management. Surgery is generally indicated in EP. However, EP can also managed conservatively. In our case, the patient developed recurrent pancreatitis, the cause being idiopathic, and the second episode of acute pancreatitis was complicated by EP and gastroduodenal artery pseudoaneurysm.

Caffeine, a popular over-the-counter methylxanthine, is widely consumed for its potent psychoactive properties. Toxicity generally occurs with intentional overdose and is often multisystemic and life-threatening. Consumption by children is rarely planned, and safe doses are potentially toxic in them. A 12-year-old boy whose parents had denied him coffee on several occasions eventually had access to it. The caffeine dose ingested was sub-toxic although he developed severe and life-threatening multisystemic caffeinism. Following ingestion, he became aggressive and was talking irrationally, with visual and auditory hallucinations. In addition, he had severe abdominal pain, multiple vomiting episodes, circulatory collapse, hypertension, angioedema, dysfunctional tear syndrome, hyperglycemia, ketonuria, hypokalemia, and metabolic acidosis. The clinical presentation, laboratory findings, and interventions are reviewed and discussed. Besides routine immunization, routine anticipatory guidance should be at the center of preventive pediatrics. Packaging of caffeinated beverages should also target the prevention of caffeine toxicity in children.
