Author Factors Influencing Quality of Sleep among Critically Ill Patients in Selected Hospitals in Western Kenya
Title Factors Influencing Quality of Sleep among Critically Ill Patients in Selected Hospitals in Western Kenya Type Journal Article
Year 2018 Publication Journal of Health, Medicine and Nursing Abbreviated Journal
Volume 56 Issue Pages
Keywords Human Health
Abstract Sleep is essential for rest, repair, well-being, and survival of the patient. Sleep quality varies in critically ill patients and is measured by patient's satisfaction of the sleep experience, integrating aspects of sleep initiation, sleep maintenance, quantity of sleep and the refreshment upon awakening. Altered sleep is a common problem experienced by patients in critical care units. This alterations may lead to physiological and psychological dysfunctions that may affect recovery. Critically ill patients frequently experience poor sleep, characterized by frequent disruptions and loss of circadian rhythms. This study investigated factors influencing the quality of sleep among critically ill patients in hospitals in Western Kenya. A cross-sectional descriptive research design was used to examine these factors. A total of 142 patients above 18 years who were admitted to the Intensive Care Unit (ICU) and those transferred from the ICU to the general ward during the study period were conveniently selected for participation in the study. For triangulation, 10 nurses who worked in the ICU also participated in the study. A structured questionnaire was used to collect data from patients while a checklist was used to observe nursing interventions. Descriptive statistical techniques used were frequencies and percentages, while chi-square was used with the p-value set at 0.05 to test the association between factors and quality of sleep. The study results showed that frequent, nursing care activities 96.5% (n=137) noise from ventilator alarms 83.1% (n=118), feeling thirsty 57.7% (n= 82) and pain 52.8% (n=75) were among the major factors influencing the quality of sleep in ICU. A one-way analysis of variance (ANOVA) revealed patient factors significantly associated with quality sleep were age p=.006 and marital status p=.02, environmental factors significantly affecting sleep were presence of light at night with a p <0.0001 and noise from alarms p=.01. Physiological factors included feeling of thirst and hunger (p=0.03). This study recommends optimal use of analgesics and sedatives for pain management, adequate fluid replacement and hydration, noise reduction strategies, including minimizing monitor and ventilator alarms, reducing staff and telephone conversations and use of ear plugs for patients in ICU. Further, nurses should implement clustered procedures to reduce disruption of sleep among critically ill patients.

Title Epigenetics: A Bridge between Artificial Light at Night and Breast Cancer Type Journal Article
Year 2019 Publication Punjab University Journal of Zoology Abbreviated Journal
Volume 34 Issue 2 Pages 231-238
Keywords Review; Human Health
Abstract The second most frequent cancer all over the world is breast cancer (BC). It is

reported that only about 10% BC cases are attributed due to inherited genetic mutations while remaining 90% cancer cases are associated with environmental factors. Artificial light at night (ALAN) is considered one of the major environmental risk factors for breast cancer. It inhibits production of melatonin (MLT) from pineal gland which results in abnormal epigenetic changes that relates with an increased risk of BC. The most important ALAN-mediated epigenetic changes include methylation of DNA and acetylation of histone, which are significant for growth, development and progression of BC. DNA hypermethylation of promoter CpG islands inhibits transcriptional activity by methyltransferase enzyme which results in inactivation of tumor suppressor genes (TSG), while in hypomethylation, demethyltransferase enzyme causes the activation of oncogenes by promoting transcriptional activity. Contrary to DNA methylation, histone acetylation and deacetylation results in chromatin opening and closing, respectively; leading to transcriptional activation and inactivation of genes. Histone acetylation has been frequently detected in oncogenes while histone deacetylation in TSG. Collective data from various studies demonstrate that DNA hypermethylation and histone deacetylation of TSG lead to inactivation of TSG and activation of oncogenes. The purpose of this review is to discuss the evidence based relationship between ALAN and oncogenes expression through epigenetic remodeling by DNA methylation and histone acetylation.

Title Why conservation biology can benefit from sensory ecology Type Journal Article
Year 2020 Publication Nature Ecology & Evolution Abbreviated Journal
Volume 4 Issue Pages 502-511
Keywords Conservation; Animals; Vision
Abstract Global expansion of human activities is associated with the introduction of novel stimuli, such as anthropogenic noise, artificial lights and chemical agents. Progress in documenting the ecological effects of sensory pollutants is weakened by sparse knowledge of the mechanisms underlying these effects. This severely limits our capacity to devise mitigation measures. Here, we integrate knowledge of animal sensory ecology, physiology and life history to articulate three perceptual mechanisms—masking, distracting and misleading—that clearly explain how and why anthropogenic sensory pollutants impact organisms. We then link these three mechanisms to ecological consequences and discuss their implications for conservation. We argue that this framework can reveal the presence of ‘sensory danger zones’, hotspots of conservation concern where sensory pollutants overlap in space and time with an organism’s activity, and foster development of strategic interventions to mitigate the impact of sensory pollutants. Future research that applies this framework will provide critical insight to preserve the natural sensory world.

Title Development of Solar Power Intelligent Street Lights System Type Journal Article
Year 2019 Publication International Journal of Scientific and Research Publications Abbreviated Journal
Volume 9 Issue 6 Pages
Keywords Lighting; Energy
Abstract The lack of natural light during night time in the urban environment has always been a problem. From people not being able to see where they are going, to the greater chance of being attacked or mugged at night which as we all know is a problem that has been in existence since humans started living together. The main advantage of this system exists in the reduction of costs related to energy consumption by the street light by integrating a vehicle/human detection algorithm into the system. The introduction of this vehicle/human detection algorithm further reduces the power consumption costs. In this project, solar PV is used to supply the energy to charge the battery. The battery later powers the operation of the whole system. The 12- 17V of the solar is buck to a steady 12V for battery charging. A light sensor is connected to the microcontroller that sense the light during day time, when the presence of day light is sensed the microcontroller turns ON the mosfet of the buck converter. If the voltage of the solar PV is greater than 12V, it charges the battery and switches off the load transistor. But at dawn, when the solar PV voltage is less than 12V the microcontroller turn OFF the buck converter mosfet and switch ON the load transistor. When no vehicle or human is detected for 10mins the microcontroller dims the LED lamp. If vehicle or human is detected the microcontroller brighten the LED lamp and inform the next microcontroller to brighten its LED lamp. If the next street light did not detect a vehicle or human after 10 mins it dims the lamp but if it detects a vehicle or human the lamp remain brightened. The microcontroller uses the ultrasonic sensor to detect object and the PIR sensor to detect human. The RF module is used for communication between the microcontrollers to inform each other the presence of vehicle or human.

Title Morfología urbana y proceso de urbanización en Ecuador a través de la imagen satelital nocturna de la Tierra, 1992-2012 Type Journal Article
Year 2020 Publication Revista EURE-Revista de Estudios Urbano Regionales Abbreviated Journal
Volume 46 Issue 138 Pages
Keywords Remote Sensing
Abstract Resumen

El artículo analiza los procesos urbanos de los asentamientos del Ecuador por medio del uso de imágenes satelitales nocturnas, considerando la magnitud y la intensidad de la luminosidad, así como su evolución durante las últimas décadas. En una primera parte, se explica la metodología aplicada para determinar el umbral de luminosidad urbana usando las imágenes satelitales de la serie dmsp-ols. Luego se analiza la intensidad de la luminosidad, así como la magnitud de las áreas con luminosidad urbana, y sus variaciones temporales. Los resultados obtenidos concuerdan con la hipótesis de que el proceso expansivo de baja densidad presente en las ciudades del Ecuador genera una rápida extensión de los usos urbanos, que pueden resultar ineficientes desde el punto de vista económico y poco sustentables ambientalmente. Por lo que a los aspectos metodológicos se refiere, el artículo muestra las potencialidades que pueden derivarse del uso de las fuentes y los procedimientos ensayados, relativamente innovadores en el contexto latinoamericano.

Summary

The article analyzes the urban processes of the main urban areas of Ecuador through the use of nocturnal satellite images, considering the magnitude and intensity of the luminosity, as well as its evolution during the last decades. In the first part, the methodology to determine the threshold of urban luminosity using the satellite images of the dmsp-ols series is explained. Afterwards, the intensity of the luminosity is analyzed, along with the magnitude of the areas with urban luminosity, as well as their temporal variations. The results agree with the hypothesis that the expansive process of low-density development present in the cities of Ecuador, generates a rapid extension of the urban uses that can be inefficient from the economic point of view and unsustainable from the environmental perspective. Regarding the methodological aspects, the article shows the potential that can be derived from the sources and procedures tested, relatively innovative in the Latin American context.
