    Introduction: The Intensive Care Unit is a hospital location permeated by not very positive associations, with the multidisciplinary team having to deal with the pain, fears and anxiety of their patients daily and the demands of their families for comprehensive care and less suffering for the patient. Pain is a reaction of the patient with biopsychosocial factors involved. The team does not always act successfully in the face of the patient’s pain, using the psychologist as a mediator of this situation. Objective: to reflect on the role of the psychologist in the face of the patient’s pain in the Intensive Care Unit. Methodology: experience report. Results and discussion: In the intensive care unit, the patient is distant from his family members, without clothes, with monitoring of different equipment and people, with invasive care, which can be felt as threatening his integrity. Pain is an unpleasant sensory experience that may be associated with tissue damage or not. It is a difficult phenomenon to be measured, since it can be an emotional pain, activated by psychological components or not. Each person has a different intensity, manifestation and reaction to pain. There are pain scales that can be used as a strategy to adapt the best intervention in different contexts of illness. The psychologist in this unit acts focused on the patient, his family and team, because everyone involved may be interfering in the recovery process and in the experience of pain and in its coping. In this triad, attentive, neutral listening should be offered to provide psychological support and to facilitate the mediation of these relationships. Conclusion: This study points to the need to study more about the pain process in the ICU context, the role of the psychologist and the importance of humanization in this context.

  • Urban Air Pollution- An emerging concern

    Air pollution in cities and urban sectors are increasing significantly on a time scale at global level. This alarming fact is substantiated with its gravity in the sense that more than 80% of people living in urban areas are exposed to air quality levels that exceed the World Health Organization (WHO) limits. The situation world over is more critical to populations in low – income cities which are most impacted. According to the urban air quality database, 98% of cities in low – and middle income countries with more than 100 000 inhabitants do not meet WHO air quality guidelines. However, the cities in high – income countries this percentage decreases to 56%. The WHO reveals the fact that around 3000 cities in 103 countries have started measuring air pollution levels and recognizing the associated health impacts. With declines of urban air quality, the risk of stroke, heart disease, lung cancer, chronic and acute respiratory diseases, including asthma, increases for the people who live in these cities. An effort has therefore been made by the authors in this paper to explain briefly some of the relevant factors responsible for urban air pollution such as heat island effect, albedo effect, urban planning with environmental inputs, climate change, urban environment policy parameters, sustainable urban transport, environmental sustainability etc. These issues need to be addressed globally on high scientific scale for effective reduction of urban air pollution.

  • The influence of biofertilizer effect on switchgrass (Panicum virgatum) crop yield under greenhouse and field conditions in Guelph, Ontario, Canada

    Greenhouse and field experiments were conducted to test the effectiveness of biofertilizers on switchgrass (Panicum virgatum) yields compared to inorganic fertilizer and a zero-control. In the greenhouse, Variovorax paradoxus JM63, JumpStart® (Penicillium bilaii), inorganic fertilizer and control treatments resulted in significantly higher per L pot biomass yields compared to the control treatment; 2.74 (±0.24), 2.55 (±0.10), 2.52 (±0.24) and 1.34 (±0.09) g L-1, respectively. As JumpStart® is a commercially available biofertilizer, it was used in the field experiment along with inorganic and control treatments. All three treatments were applied to established (2014) switchgrass plots. Significantly (p

  • Comparative analyses of plantain vivoplants responses to different clam shells and Tithonia diversifolia treatments in terms of growth promotion and induced resistance against Mycosphaerella fijiensis

    The seeds availability and quality are the main constraints for agricultural explosion of plantain productivity in sub-Saharan Africa countries. Plantain vivoplants were generated and submitted to different treatments in the nursery, the plant responses were analysed and compared in other to determine the best treatment influencing the growth promotion and induced resistance to Mycosphaerella fijiensis. Plantain explants and vivoplants were treated with five different treatments: clam shells powder (T1), clam shells and Tithonia diversifolia powder (T2), Tithonia diversifolia flakes (T3), Tithonia diversifolia mulch (T4), Tithonia diversifolia liquid extract (T5). The treatments were applied by their incorporation in the substrate (T1, T2, T3 and T4) or by watering of the whole plant (T5). The germination rate was evaluated and recorded in the greenhouse at the germination and pre-emergence stage, followed by the agromorphological measurements on the vivoplants and their inoculation with Mycosphaerella fijiensis in the shade at the vegetative growth stage. Biochemical analysis was done on the vivoplants leaves tissues. The vivoplants respond positively to all the treatments by a quick germination and emergence, coupled with an important biomarker’s accumulation (total proteins and phenolics). It turns out that the best treatment was T5 (T. diversifolia liquid extract), followed by T4 (T. diversifolia mulch). However, depending on the expected response in the vivoplants, all these treatments have proven to be impactful. Therefore, a combination of Tithonia diversifolia liquid extract (T5) with clams’ shells (T1) could be useful to boost the production at low cost and without chemical inputs of large amount of improved vigorous (clean and less susceptible) planting material, impacting thus the food security and poverty alleviation.


    Social science believes that religion is a cultural phenomenon that has emerged in the development of human society to a certain historical stage, an illusory reflection of the objective world, and a social ideology. Primitive religions, also known as tribal religions, refers to the religions of the ancient times and the religions of uncivilized society, such as nature worship, elf worship, totem worship, witch cult, etc. Art refers to a social ideology that uses images to reflect reality but is more typical than reality, including literature, calligraphy, painting, sculpture, architecture, music, dance, drama, film, and Chinese Quyi. There is a close relationship between art and religion, and their production and development are closely linked.

  • Determining the Best Plan for Malls Parking Lot Based on Fuzzy Analytic Hierarchy Process Model

    With the rapid development of social economy, the number of family cars has entered a period of rapid growth and the consequent urban parking problem has become increasingly prominent, gradually becoming one of the problems facing cities in China. The regional planning of parking spaces can expand the number of parking spaces within a unit area. Therefore, considering safety, convenience, efficiency and other factors, how to maximize the number of parking spaces is the key to solve the parking problem. Based on the triangle division of Abdelfattah model and the analysis of PSU planning theory, the planning of mall parking lot is more realistic. This kind of planning maximizes the number of parking spaces on the basis of greatly increasing the flexibility of vehicle entry and exit, which is more conducive to our life.

  • Primary Mucosal Melanoma Mimicking High Grade Urothelial Carcinoma: A Potential Diagnostic Pitfall

    Primary malignant melanomas of the genitourinary tract are rare, representing < 1% of all cases of melanoma1,2. We report a case of a 68-year-old female patient with primary malignant melanoma of the urethra with morphology mimicking that of high grade papillary urothelial carcinoma. The patient presented following a workup with an outside urologist that revealed a urethral mass. The patient complained of urinary incontinence and pelvic pain at initial presentation. A CT scan of the abdomen & pelvis revealed a soft tissue density within the vaginal vault, consistent with urethral cancer. A cystoscopy and urethral excisional biopsy was performed. Histologic examination of the specimen revealed an invasive tumor composed of epithelioid cells with prominent eosinophilic cytoplasm forming papillary structures. However, the tumor cells were negative for CK7, CK20, GATA 3 and Pancytokeratin and positive for S-100, SOX 10 and Melan A. The case was ultimately diagnosed as malignant melanoma.

  • Predicting Traffic Congestion Time Based on Kalman Filter Algorithm

    This paper mainly solved the problem of predicting the time required for vehicles to pass through congested roads. In order to obtain more accurate prediction time, a Kalman prediction model based on multiple linear regression was established in this paper. Taking the 2008 Yanan elevated road in Shanghai as an example, the measured data in this section was collected from the traffic measured data sharing network, and the above model was used to obtain good prediction results. As an improvement, we used BP neural network instead of multiple linear regression to make the prediction result more in line with the actual situation.

  • Rhabdomyolysis requiring emergency dialysis as a consequence of simultaneous administration of simvastatin and clarithromycin

    Iatrogenic complications from polypharmacy have significantly increased over the past decade and clinicians and pharmacists must remain aware of potentially dangerous drug interactions 1–3. Our case is a reminder of the potential for significant patient harm from drug interactions when additional medication that is seemingly innocuous is prescribed in addition to a patient’s regular long-term medications. Our case also highlights the diagnosis and management of rhabdomyolysis and acute kidney injury. A 75-year-old Caucasian male presented to the emergency department with nausea, bilateral calf tenderness and a reduced urine output. Creatinine Kinase (CK) levels demonstrated severe rhabdomyolysis and the patient’s creatinine was significantly elevated with a concurrent metabolic acidosis requiring urgent renal replacement therapy in the intensive care unit (ICU). He was recently prescribed clarithromycin 500mg twice daily as part of Helicobacter pylori eradication therapy in addition to his regular combination therapy of simvastatin 80 mg and ezetimibe 10 mg daily dose. Statins may cause dose dependent Statin Associated Myopathies (SAMs) such as myositis and rhabdomyolysis and are metabolised by the hepatic cytochrome P450 (CYP450) 3A4 enzyme4,5. Clarithromycin is a potent CYP450 3A4 hepatic enzyme inhibitor that leads to significantly elevated plasma levels of statin medications, increasing the risk of SAMs4,6–8. Our patient responded to the cessation of the offending medications and initiation of continuous renal replacement therapy. This case demonstrates the dangerous side effects and interactions of commonly prescribed medications.
