Factors associated with knowledge and practice regarding oxygen administration: A cross-sectional study among registered nurses working in wards and ICUs at Muhimbili National Hospital in Dar es Salaam, Tanzania
Authors: Kimario Magdalena S. , Ambikile Joel Seme , Iseselo Masunga K. 
Published: January 2025

Background
Oxygen is a vital therapy approved by WHO, crucial for critically ill patients as a supplemental treatment. Nurses’ pivotal role in oxygen administration is poorly understood. This study aimed to assess factors associated with oxygen administration to critically ill patients among nurses at Muhimbili National Hospital (MNH) in Dar es Salaam, Tanzania.

Methods
A descriptive cross-sectional study was conducted among 208 nurses using a simple random technique to recruit respondents. Data were collected in May 2022 via a self-administered questionnaire, designed and tested by the authors. Mean knowledge and practice scores were used to categorize knowledge and practice as high or low respectively. The Chi-square test and multiple logistic regression analyses were performed to evaluate factors associated with knowledge and practice regarding oxygen administration. Statistical significance was determined at a p-value less than 0.05.

Results
Of the 208 respondents, 96(46.2%) and 78(37.5%) had low knowledge and low practices regarding oxygen administration, respectively. Receiving in-service training on oxygen administration (AOR: 3.515; p<0.001) was positively associated with knowledge of oxygen administration. None of the factors showed a statistically significant association with the practice of oxygen administration.

Conclusion
A substantial proportion of nurses had inadequate knowledge and practices regarding oxygen administration. While none of the assessed factors were found to have a statistical association with practice on oxygen administration, it is important to note their clinical significance. Healthcare institutions can benefit from implementing regular in-service training programs to address these knowledge and skills gaps and ensure that nurses are well-prepared for proper oxygen administration. Additionally, ongoing monitoring and support are essential to help translate improved knowledge into effective clinical practices.
Association between maternal mental health and early childhood development, nutrition, and common childhood illnesses in Khwisero subcounty, Kenya
Authors: Abajobir Amanuel , Maina Daniel , Wambui Elizabeth , Sidze Estelle M. 
Published: January 2025

Background
Despite the significant public health burden of maternal mental health disorders in sub-Saharan Africa (SSA), limited data are available on their effects on early childhood development (ECD), nutritional status, and child health in the region.

Aims
This study investigated the association between maternal mental health and ECD, nutritional status, and common childhood illnesses, while controlling for biological, social, financial, and health-related factors and/or confounders.

Method
As part of the Innovative Partnership for Universal and Sustainable Healthcare (i-PUSH) program evaluation study, initiated in November 2019, a cohort of low-income rural families, including pregnant women or women of childbearing age with children under five, was recruited for this study. A total of 24 villages were randomly selected from a list of villages near two health facilities. Following a census to identify eligible households, 10 households per village were randomly selected. Data collection included maternal mental health, assessed using Centre for Epidemiological Studies Depression (CES-D) scale, ECD, nutritional status (anthropometric measurements), and common childhood illnesses, their symptoms, and healthcare utilization. This study presents a cross-sectional analysis of the data drawn from endline survey of 299 target mothers and 315 children.

Results
The majority of the mothers were aged between 25 and 34 years. The mean age of children was 3.2 years, with 53% being male. The overall maternal mental health score, as measured by the CES-D scale, was 28. Children of mothers with higher CES-D scores exhibited poorer ECD domains, lower nutritional status indicators, and increased incidence of ill-health in the previous two weeks, in both unadjusted and adjusted analyses. Individual, parental, and household factors—including maternal age, household wealth index, and decision-making regarding child healthcare—were significantly associated with children’s development, nutrition status, and health outcomes.

Conclusion
Children of mothers with low mental health scores demonstrated suboptimal developmental outcomes, nutritional status, and overall well-being, particularly for those from impoverished households. These findings suggest that improving the socioeconomic conditions of low-income households is essential for promoting children’s development, nutritional status, and well-being. Longitudinal studies are needed to further investigate the impact of maternal mental health on child development, nutrition, and health outcomes, considering additional factors across the maternal, newborn, and child health continuum.

Super-sized electric vehicles (EVs) will not solve the climate crisis
Authors: Gottesfeld Perry 
Published: January 2025

Electric vehicles (EVs) are growing in size along with their increase in market share. At the same time, auto producers are responding to range anxiety by increasing battery capacity. The mean weight of the lithium-ion batteries in the most common vehicles sold in 2023 were 68% heavier than the models sold 5 years earlier. Larger size EVs with greater range require heavier lithium-ion batteries with more energy intensive inputs and greater lifetime carbon emissions. Consumer messaging glosses over the energy and environmental impacts of increasingly larger EVs with heavier batteries. Government subsidies and tax incentives should be better aligned to account for greenhouse gas emissions over the vehicle lifecycle.
Periodontitis and the Incidence of Inflammatory Bowel Diseases: A Nationwide Population-Based Cohort Study
Authors: Park Yehyun , Park Jung-Hyun , Leem Gwang Hyun , Song Tae-Jin 
Published: January 2025

INTRODUCTION:
Periodontitis and other oral health indicators are reportedly related to systemic inflammation. Our study aimed to investigate a possible association of oral health status (periodontitis and number of missing teeth) and oral hygiene behaviors (frequency of tooth brushing, dental visit, and dental scaling) with the risk of inflammatory bowel disease (IBD) incidence.

METHODS:
Using the Korean National Health Insurance Database, we conducted a nationwide, population-based cohort study involving participants from the 2003 national health screening program. We followed these individuals until December 2020 or the occurrence of censoring events. Crohn's disease (CD) and ulcerative colitis (UC) were defined by disease classification codes from the International Classification of Diseases-10 and national codes for rare intractable disease. The occurrence of IBD was analyzed using the Cox proportional hazard model, with propensity score matching performed to balance baseline characteristics between participants with and without periodontitis.

RESULTS:
Our analysis involved a total of 2,272,012 participants with a median follow-up period of 17.0 years. The incidence rates for CD and UC were 11.6 and 32.4 per 100,000 person-years, respectively. In multivariable analysis after propensity score matching, the presence of periodontitis was associated with an increased risk of both CD (adjusted hazard ratio [aHR] 1.32, 95% confidence interval [CI] 1.14–1.52, P < 0.001) and UC (aHR 1.21, 95% CI 1.10–1.32, P < 0.001). Conversely, frequent tooth brushing ≥3 times a day was associated with a reduced risk of CD (aHR 0.81, 95% CI 0.65–0.99, P = 0.049), but no significant association was observed with UC.

DISCUSSION:
Periodontitis may augment the risk of incidence for CD and UC. This association underscores the potential significance of periodontal health in the context of IBD, emphasizing the importance of comprehensive oral hygiene practices and potential preventive strategies to reduce the risk of CD and UC incidence.

One-pot fabrication of highly porous morphology of ferric oxide-ferric oxychloride/poly-O-chloroaniline nanocomposite seeded on poly-1H pyrrole: Photocathode for green hydrogen generation from natural and artificial seawater
Authors: Rabia Mohamed , Alnuwaiser Maha Abdallah 
Published: January 2025

Abstract
A novel photocathode has been fabricated, featuring a highly porous ferric oxide-ferric oxychloride/poly-O-chloroaniline (Fe2O3-FeOCl/POCA) nanocomposite, integrated onto a poly-1H pyrrole substrate. This photocathode was synthesized using a one-pot technique, which involves the oxidation of o-chloroaniline in the presence of iron sources, resulting in the incorporation of iron oxide and iron oxychloride within the polymer matrix. The photocathode exhibits broad optical absorption extending into the IR region and has a promising bandgap of 1.74 eV, making it a strong candidate for hydrogen gas generation within a constructed three-electrode cell. The photocathode’s performance in natural seawater is impressive, with an estimated hydrogen production rate of 20 µmol/h per 10 cm2. Electrochemical measurements indicate a current density of −0.015 mA/cm2 under these conditions. When tested with artificial seawater that is free of heavy metals, the current density (J
ph) is slightly lower at −0.013 mA/cm2. Furthermore, the photocathode demonstrates excellent sensitivity to various photon energies across wavelengths ranging from 730 to 340 nm, achieving J
ph values of −0.0145 and −0.012 mA/cm2, respectively. The green chemistry approach used in this photocathode’s fabrication, combined with its environmentally friendly operation, highlights its potential for commercial applications. This development could pave the way for industrial-scale production of photoelectrodes designed to convert seawater into hydrogen gas, contributing to sustainable energy solutions.
Vector spatial and spatiotemporal laser solitons

Published: January 2025

Abstract
Dissipative optical solitons, i.e. packets of radiation localized not due to the presence of optical inhomogeneities of the scheme or medium, but due to the balance of energy inflow and outflow in a nonlinear medium, deserve special attention for a number of reasons. First, these solitons are “calibrated” with a discrete set of basic parameters. This will lead to their increased stability: dissipative solitons are attractors, they are not sensitive to small perturbations. Second, progress in laser technology and the emergence of new laser and nonlinear optical materials provides an opportunity not only to study the rich physics of dissipative solitons, but also to propose their promising applications. This paper, which combines both a review of the current level of theory and original results, is devoted mainly to new types of these solitons. These types exploit the topological features of structured radiation, characteristic of vector, polarization dissipative solitons, which have a nontrivial internal structure. We sequentially present one-dimensional (1D), two-dimensional (2D) and three-dimensional (3D) polarization solitons, identify limitations in the topological protection of the information that can be encoded by topological charges and indices and discuss development prospects in this area.
Superior colliculus controls the activity of the substantia nigra pars compacta and ventral tegmental area in an asymmetrical manner

Published: January 2025

Dopaminergic (DA) neurons of the substantia nigra pars compacta (SNc) and ventral tegmental area (VTA) play a crucial role in controlling animals’ orienting and approach behaviors toward relevant environmental stimuli. The ventral midbrain receives sensory input from the superior colliculus (SC), a tectal region processing information from contralateral receptive fields of various modalities. Given the significant influence of dopamine release imbalance in the left and right striatum on animals’ movement direction, our study aimed to investigate the lateralization of the connection between the lateral SC and the midbrain DA system in male rats. We explored the circuit's anatomy using transsynaptic viral tract-tracing, and its physiology using in vivo single unit and ex vivo multielectrode array recordings of SNc and VTA neuronal activity combined with optogenetic stimulation of either ipsilateral or contralateral SC or its terminals. During the experiments, DA neurons were identified optogenetically (in vivo recordings) or pharmacologically (ex vivo recordings). Anatomical findings revealed a bilateral innervation pattern of the lateral SC to the ventral midbrain, with a significantly stronger ipsilateral connection, particularly evident in the SNc, involving both DA and non-DA neurons. This anatomical asymmetry was also expressed during in vivo and ex vivo recordings, which showed a predominance of ipsilateral connection, especially within the SNc. Ex vivo recordings also confirmed that this lateralized pathway is direct. The described features of the SC to VTA/SNc neuronal circuit, particularly its anatomical and physiological asymmetry, suggest its involvement in orienting and approach behaviors guided by the direction of incoming sensory stimuli.Significance statementThe direction of animals' behavior is a manifestation of asymmetry in dopamine (DA) release between the left and right striatum – unilateral activation of DA neurons biases movement towards the contralateral side. Our study demonstrates that such activation is induced by the ipsilateral superior colliculus (SC), which processes sensory information from the contralateral body side. Notably, our previous findings indicate that the SC innervates and activates the rostromedial tegmental nucleus, a primary inhibitory input to the DA system, albeit in the contralateral hemisphere. Thus, our research describes a SC-originating neuronal circuit that directly enhances the activity of ipsilateral DA neurons while simultaneously diminishing the activity of contralateral DA neurons, thereby amplifying the imbalance in DA release between the hemispheres.

Las habilidades lectoras hacen parte fundamental del desarrollo de las competencias comunicativas que incluye elementos de la sintaxis y la semántica para interpretar los eventos comunicativos. En el caso de las personas que presentan discapacidad visual, el desarrollo de estas habilidades se ve afectado a lo largo de su proceso de formación en los ambientes de aprendizajes que se encuentran inmersos y que carecen de herramientas, recursos o estrategias de innovación educativa que responda a las necesidades propias de ellos. Para un buen desarrollo integral de las personas ciegas se requiere adquirir habilidades en la lectura y escritura mediante el uso de códigos alternativos como el sistema Braille, que representa la forma de acceder a la información y transmitir los conocimientos aprendidos, en este sentido, proponer las multimedia interactivas como estrategia que ayude a fortalecer los procesos lectoescritores del sistema Braille por medio de la implementación de recursos táctiles y auditivos facilita al estudiante interiorizar y mejorar aspectos del lenguaje para la organización sintáctica, semántica y la conciencia fonológica. La importancia de esta investigación cualitativa se basa en la implementación de la metodología de la investigación acción participación (IAP), el cual utiliza como técnica de recolección de información la sistematización de las experiencias obtenidas en la aplicación de los instrumentos que conllevan a los resultados esperados. El aprendizaje de la lectoescritura Braille se observa como un proceso analítico – asociativo que permite la interacción con la información que fortalece las habilidades de pensamiento posibilitando la planeación, organización y autorregulación del aprendizaje; por tanto, la apropiación de los códigos del sistema Braille en las personas ciegas, junto con el acompañamiento del docente y el usos de estrategias de enseñanza se convierte en la oportunidad para desarrollar las competencias y mejorar los resultados en la adquisición de la lectoescritura.

Published: January 2025

Abstract
Accurate identification of fracture systems is crucial for analyzing the causal mechanisms of induced earthquakes. Previous studies have been constrained by the low resolution of seismic reflection profile analyses, limiting the characterization of fracture zones with small displacements and short extensions, and hindering the identification of seismogenic structures. This study focuses on the Hutubi gas storage (HUGS) field in Xinjiang, China, a region prone to frequent small-magnitude earthquakes. Although most seismogenic structures in this region are understood, uncertainties remain due to a few earthquake clusters with unconfirmed structures, complicating seismic risk assessment. Utilizing high-resolution 3D seismic reflection data, we identified and explored the seismogenic structures of small-magnitude earthquakes in the peripheral region of HUGS. The causal mechanisms ranged from pre-existing faults to extensive fracturing at various scales around HUGS. We developed a deep-learning-based method for identifying multiscale faults and fractures and applied it to study the seismogenic structures. Large-scale faults and fractures were first identified, and the reliability of this intelligent identification was evaluated alongside manual interpretation. Sample-adaptive methods were then employed to resample the seismic dataset multiple times, identifying small- and medium-scale faults and fractures. Finally, we combined the multiscale identification results with precise earthquake locations to determine the seismogenic structures. The study found that stress perturbations within the HUGS field induce seismic activity along pre-existing faults and small-scale fractures, influencing the spatial distribution of shallow, small-magnitude seismic events. In addition, earthquake clusters on the southeastern margin of HUGS are likely due to stress concentration along the fold axis, leading to intralayer slip and activation of near-surface parallel fractures. These findings suggest that deep-learning-based multiscale fault and fracture identification offers a detailed perspective for studying seismogenic structures and assessing seismic hazards.

La pubertad es el periodo en el que se producen cambios físicos, hormonales, psicológicos y emocionales que marcan la diferencia entre la niñez y la adultez. Su inicio depende de la interrelación de mecanismos complejos con múltiples niveles de regulación que involucran desde el sistema nervioso central hasta las gónadas. Los eventos principales son la gonadarquia y la adrenarquia, que determinan la aparición y progresión de los caracteres sexuales secundarios. Los esteroides sexuales actuando en forma sinérgica con la hormona de crecimiento son responsables del empuje puberal. La pubertad se produce por una secuencia ordenada de eventos que presentan un patrón diferente en varones y mujeres. El conocimiento sobre la pubertad normal y sus variantes permitirá al Pediatra reconocer los cuadros de desarrollo sexual precoz, cuya detección temprana, así como la derivación oportuna al Endocrinólogo Pediatra para su manejo, beneficiará a aquellos que requieran alguna intervención terapéutica.
