Sleep Patterns of Medical Students in Ahmedabad: A Cross Sectional Study

Back ground: Sleep pattern is related to psychological, clinical, and social aspects. The medical student population is one of the populations that appear to be at increased risk for sleep deprivation. Sleep deprivation has been found to affect cognitive function in medical students. Objectives: To assess the sleep pattern among medical students. Methodology: A cross-sectional questionnaire-based study was done in 400 medical students. Questionnaire includes general information, sleeping patterns details and The Epworth Sleepiness Scale (ESS). Data analysis was done by Microsoft Excel and Epi-Info. Results: 80.75% students had sleep of 7 to 10 hours daily and 69.75% students were taking mid-day nap. 44.25% students were studying 4 to 6 hours daily. The Epworth Sleepiness Scale was normal in 63% participants. Conclusion: Medical students who suffer from sleep deprivation run a major risk of compromising their health but also are prone to commit medical errors in the care of patients.
Energy mix as the basic regularity of the principles of sustainable development

Energy sources are a basic factor of economic development. Within the framework of the climate and energy policy of the European Union (EU), the rural areas that allow the use of renewable energy sources become more important. The aim of the article is to show the direct impact of contemporary EU policy in this area on the economic situation of states. At the same time, we are developing recommendations for the EU regarding future climate and energy policy by analysing empirical data developed by the world's largest organizations and institutions, such as the International Atomic Energy Agency, the World Nuclear Association, Eurostat and the International Energy Agency, and practices used by EU countries. The basis of the presented considerations and recommendations is a review of the subject literature and statistical analysis of empirical data. Conclusions are presented in accordance with the economic effectiveness of various energy sources and the principles of sustainable development.
Outcome of mechanical ventilation in children infected with the human immunodeficiency virus

Objective. To evaluate and compare the outcome of HIV-positive (HIV+) and negative (HIV-) paediatric patients presenting with severe community-acquired pneumonia and requiring mechanical ventilation for respiratory failure. Design. Prospective descriptive analysis. Setting. Multidisciplinary intensive care unit (ICU) in a tertiary care university-based referral hospital, staffed by paediatric intensivists and anaesthetists. Patients. Multidisciplinary intensive care unit (ICU) in a tertiary care university-based referral hospital, staffed by paediatric intensivists and anaesthetists. Patients. All 110 paediatric patients admitted to the ICU with severe community-acquired pneumonia requiring mechanical ventilation during the 2 years 1992 through 1993. No patient had any defined clinical manifestations of acquired immunodeficiency syndrome on admission to the ICU. Methods. HIV infective status was determined by p24 antigen detection. Age, nutritional status, predicted mortality, ventilatory requirements, oxygenation indices, other organ dysfunction and mortality were compared between the 17 HIV+ and 93 HIV - patients. Results. The patient groups did not differ significantly with regard to age or nutritional status. The ventilatory requirement measurements, positive end-expiratory pressure time product, fraction of inspired oxygen (FiO 2 ) time product, and measurements of oxygenation were significantly worse in HIV+ patients. HIV+ patients had a mean predicted mortality of 40.1% compared with 22.2% in HIV-patients on admission. Mortality was close to predicted in the HIV-group at 31% (29/93), while in the HIV+ patients mortality at 88% (15/17) was significatly worse than predicted. All deaths in the HIV+ group were due to severe respiratory failure. Conclusions. Children with HIV infection who present with severe community-acquired pneumonia requiring ventilation prior to any other clinical manifestations of AIDS have a high ICU mortality rate. Regular re-evaluation of management protocols in such patients is required, particularly in centres where resources are limited.
Choosing between personal values: The Pavlovian substrates of intrinsic preferences

Several brain circuits interact in computing the value of choices between options, as when we express our preference between a set of available consumer goods. Here, we used a procedure developed in functional neuroimaging studies of consumer choice to identify the neural substrates activated by choosing between values that, when put into practice, can give meaning to one’s life, such as achievement, community, tradition, or religion, and are unrelated to material needs or financial security. In a first sample (N=18), instead of the neural substrates usually associated with choice between consumer goods, we found activation of the amygdala, a limbic system structure which presides over assignment of values to stimuli according to immediate affective experience and promotes responses according to their association with potential rewards. This unexpected finding was replicated in a second independent sample (N=18). These results are consistent with views arguing for the existential nature of values that give meaning to one’s life here and now, in contrast to maximizing long-term utility.

Impact of Seaweed-derived Xanthophyll Carotenoid on Obesity Management: Overview of the Last Decade

Present-day lifestyle associated with high calorie-fat intake and accumulation, as well as energy imbalance, has led to the development of obesity and its comorbidities, which have emerged as some of the major health issues globally. To combat the disease, many studies have reported the anti-obesity effects of natural compounds in foods, with some advantages over chemical treatments. Carotenoids, particularly xanthophyll derived from seaweeds, have attracted the attention of researchers due to their notable biological activities, which are associated mainly with their antioxidant properties. Their involvement in oxidative stress modulation, regulation of major transcription factors and enzymes as well as their antagonistic effects on various obesity parameters have been examined in both in-vitro and in-vivo studies. The present review is a collation of published research over the last decade on the anti-oxidant properties of seaweed xanthophyll carotenoids, with a focus on fucoxanthin and astaxanthin and their mechanisms of action in obesity prevention and treatment.
Method for Quantitative Broadband Diffuse Optical Spectroscopy of Tumor-Like Inclusions

A hybrid reflectance-based diffuse optical imaging (DOI) technique combining discrete wavelength frequency-domain (FD) near-infrared spectroscopy (NIRS) with broadband continuous wave NIRS measurements was developed to quantify the broadband optical properties of deep tumor-like inclusions. This method was developed to more accurately measure the broadband optical properties of human tumors using a compact handheld imaging probe and without requiring a priori spectral constraints. We simulated the reconstruction of absorption and scattering spectra (650–1000 nm) of human breast tumors in a homogeneous background at depths of 0 to 10 mm. The hybrid DOI technique demonstrated enhanced performance in reconstruction of optical absorption with a mean accuracy over all 71 wavelengths of 8.39% versus 32.26% for a 10 mm deep tumor with the topographic DOI method. The new hybrid technique was also tested and validated on two heterogeneous tissue-simulating phantoms with inclusion depths of 2, 7, and 9 mm. The mean optical absorption accuracy over all wavelengths was similarly improved up to 5x for the hybrid DOI method versus topographic DOI for the deepest inclusions.
COOPERATIVE LEARNING DESIGN IN WEB MEDIA: CONCEPTUAL REVIEW

This paper proposes the conceptual feasibility of designing cooperative learning on web media. Web-based cooperative learning is done by incorporating elements of cooperative learning on the web. Various cooperative learning studies are used as a basis for building cooperative learning steps designed. Preparation before implementing cooperative learning on a website plays an important role. The initial process of preparing cooperative learning on the web: 1) Preparing data about students, 2) Developing an activity plan including objectives, 3) Determining teaching materials, 4) Organizing groups of students, 5) Planning weight values, 6) Determining action instruments (observation sheets, learning outcomes test, questionnaire about learning responses). The results of the study formulate cooperative learning steps on the web using forum chat facilities: 1) Present goals and instruction sets; 2) Arrange students to become learning teams; 3) Helping team work and learning; 4) Test material; 5) Give recognition.
Determinants and Moderators of Intention to Purchase using Social Commerce

Social commerce (SC) is an increasingly popular form of electronic commerce that involvesthe use of social network sites (SNS) as commercial platforms. It is important for practitioners fromthe SC industry and SC researchers to understand which factors drive a user’s intentions to purchasegoods and services using SC. This study proposes a theoretical model of factors derived fromprevious studies which have causal or moderating effects on an individual’s intentions to makepurchases using SC. The model is analyzed and developed using data collected from a sample of399 SC users. The study makes three contributions to theory: insights based on direct, indirect,and total effects rather than only direct effects; the study of social support variables; and theinvestigation of moderating effects due to gender, age, and SC experience. The findings confirmseveral results from previous studies and identify new results.
Cardiovascular manifestations in patients treated with periodic hemodialysis through functional arteriovenous fistula

 A Alonso Herrera Cardiocentro Ernesto Che Guevara Cuba 610, e/ Barcelona y Capitán Velasco. Santa Clara, CP 50200. Villa Clara, Cuba. E-mail address: alainalonsoh@infomed.sld. cu ABSTRACT Introduction: Cardiovascular manifestations produced by the arteriovenous fistula in patients treated with hemodialysis are an important aspect, as cardiovascular disease is the leading cause of morbidity and mortality. Objective: To determine the cardiovascular manifestations in patients with a functional arteriovenous fistula treated with regular hemodialysis. Method: Descriptive, transversal study, with 81 patients in dialysis treatment who had a functional arteriovenous fistula. Clinical records were reviewed, and a transthoracic echocardiogram was carried out. Association between variables was determined by statistical tests. Results: There was a significant difference in the hemodialysis treatment time in patients with hypertrophic cardiomyopathy, 70% in less than 4 years against 100% in more than 4 years (p=0.03), valve diseases 67.4 vs. 94.3% (p=0.03), and pulmonary hypertension 26.1 vs. 57.1% (p=0.05); and also regarding the diameter of the left atrium 45.1±4.7 mm, less than 4 years, against 50.9±7.6 mm, more than 4 years (p=0.00). E' wave velocity 7.9±1.4 cm/s vs. 7.2±1.7 cm/s (p=0.045). Interventricular septum 16.4±3.1 mm vs. 18.5±4.9 mm (p=0.021), and posterior wall 14.6±2.5 vs. 16.5±3.1 mm (p=0.003); as well as mean pulmonary artery pressure 25.6±7.5 mmHg vs. 29.3±8.4 mmHg (p=0.042). Conclusions: No relationship was found between the fistula location and changes in the cardiovascular system. The group of patients with more than four yearsfistula presented major cardiovascular events and significant changes in the echocardiogram.
Microbial Monitoring in the EDEN ISS Greenhouse, a Mobile Test Facility in Antarctica

The EDEN ISS greenhouse, integrated in two joined containers, is a confined mobile test facility in Antarctica for the development and optimization of new plant cultivation techniques for future space programs. The EDEN ISS greenhouse was used successfully from February to November 2018 for fresh food production for the overwintering crew at the Antarctic Neumayer III station. During the 9 months of operation, samples from the different plants, from the nutrition solution of the aeroponic planting system, and from diverse surfaces within the three different compartments of the container were taken [future exploration greenhouse (FEG), service section (SS), and cold porch (CP)]. Quantity as well as diversity of microorganisms was examined by cultivation. In case of the plant samples, microbial quantities were in a range from 102 to 104 colony forming units per gram plant material. Compared to plants purchased from a German grocery, the produce hosted orders of magnitude more microorganisms than the EDEN ISS plants. The EDEN ISS plant samples contained mainly fungi and a few bacteria. No classical food associated pathogenic microorganism, like Escherichia and Salmonella, could be found. Probably due to the used cultivation approach, Archaea were not found in the samples. The bioburden in the nutrition solutions increased constantly over time but never reached critical values like 102–103 cfu per 100 mL in irrigation water as it is stated, e.g., for commercial European plant productions. The surface samples revealed high differences in the microbial burden between the greenhouse part of the container and the SS and CP part. However, the numbers of organisms (bacteria and fungi) found in the planted greenhouse were still not critical. The microbial loaded surfaces showed strong temporal as well as spatial fluctuations. In samples of the nutrition solution and the surface, the amount of bacteria exceeded the amount of fungi by many times. For identification, 16S rRNA gene sequencing was performed for the isolated prokaryotic organisms. Phylogenetic analyses revealed that the most abundant bacterial phyla were Firmicutes and Actinobacteria. These phyla include plant- and human-associated bacterial species. In general, it could be shown that it is possible to produce edible fresh food in a remote environment and this food is safe for consumption from a microbiological point of view.

Phytophagy in a Polypedilum (Diptera: Chironomidae) species new to Australia and Japan: taxonomy and expanded Asian distribution

Polypedilum johannseni Sublette & Sublette (= Chironomus (Polypedilum) anticus Johannsen), described from Indonesia, is recorded from Australia, where larvae are newly reported to feed on species of the aquatic fern Azolla Lam. (Salviniaceae). We extend the Australian distribution for the species that was reported previously as Polypedilum ‘nr seorsus’ from northern Australia. Review of the species in Asia shows previously known presence in Singapore as Polypedilum anticus and in Thailand and the Philippines, where the larva was reported to feed on Azolla. In China, Polypedilum johannseni is reported from a diverse range of aquatic host plants, including Azolla. We also newly report the species from Japan, where larvae feed on hybrid Azolla cristata × Azolla filiculoides and Trapa japonica Flerow (Lythraceae). We review the taxonomy, provide new illustrations, record and map the wider distribution and comment on morphological variation. Here, we also redescribe the Australian Polypedilum seorsus (Skuse) with which P. johannseni has been confused, and from China, we redescribe Polypedilum tigrinum Hashimoto, the larva of which is a proven aquatic phytophage that co‐occurs with several species of Polypedilum, including P. johannseni.
Morphological Variations of Robusta Coffee As a Response to Different Altitude in Lampung

The coffee growth is considered to depend, partly, on the environmental condition at which they develop to accomplish both vegetative and generative stages. An exploratory survey in Lampung aimed at investigating the morphological characteristics of 13 Robusta coffee accessions growing on different altitudes.Local superior coffee clones were selected from eight farms, and subjected to identifications. Three key issues were concerned for both quantitatively, i.e. plant components of leaves, branches, and fruits, and qualitatively such as leaves and fruit characteristics, i.e. colour and shape. The analysis shows a similarity of about 60% of total qualitative variable identified among different accessions. The remaining characters are suggested to be more varying such as flush colour, leaf surface, ripe fruit colour, and stipule shape. Furthermore, a quantitative analysis showed a higher level of similarity for fruit characters, i.e. fruit length, -width, and -thickness, and to a slightly lower level for leaf characteristics, i.e. leaf length and -width, and number of productive branches. It was revealed that some variables, i.e. fruit weight; leaf and seed; and canopy characteristics, explaining the morphological variation of coffee throughout the accessions. Furthermore, cluster analysis may indicated a possible similarity of coffee morphologies either from area with different or the same environmental conditions. A high heterogeneity related to environmental conditions, genotypic variations, plant nutritional status, and agronomic practices, which unable to confirm in the present study, may limit the specific conclusions.
Comparisons of Group-Size, Composition and Movement of Herbivorous Reef Fish in Jamaica and Grand Cayman Island

The decline in herbivorous fishes is an important contributing factor to the degradation of coral reefs, because their reduction contributes to macro algae overgrowth, which can have harmful effects on corals. Herbivorous fish often form mixed-species groups to locate foraging sites and for defense. The movements and compositions of these groups are dependent on the relative numbers of different species present. Some species, such as the striped parrotfish (Scarus iserti) and ocean surgeonfish (Acanthurus bahianus), serve as core species that lead mixed-species groups. Others, such as the redband (Sparisoma aurofrenatum) and stoplight parrotfishes (Sparisoma viride), follow core species as their associates. Despite the potential importance and abundance of mixed-species groups on reefs, little attention has been given to their composition and movements. Our intent was to determine whether the social dynamics of mixed-species groups in Jamaica were similar to those of Grand Cayman. The overall sizes of mixed-species groups were smaller in Grand Cayman. Focal striped parrotfish in Grand Cayman formed smaller groups, changed composition less, and moved less frequently than in Jamaica. Although probably more abundant than striped parrotfish, the ocean surgeonfish in Grand Cayman did not function as a core species but rather attached themselves as associates to the smaller striped parrotfish groups. Redband parrotfish moved less often in Grand Cayman, and appeared to be more dependent on striped parrotfish groups than stoplight parrotfish. While previous studies on herbivorous reef fish have shown that changes in foraging patterns can change with location, perhaps related to structural heterogeneity and resource distribution, this study illustrates that social interactions between common members of mixed-species groups also change. We suggest that the intra and interspecific social interactions in Grand Cayman are less attuned to finding erratically located high quality resources than those in Jamaica. Other plausible explanations are also considered.
