Investigating Doctor of Physical Therapy Student Stress During Pandemic Related Curricular Changes

Introduction: Stress level in physical therapy students has been a focus of research due to multiple documented effects related to physical health, mental health, and ability to learn. Self-reflection has also been a focus of education research, relating it to personal learning, critical thinking, and demonstrable development of professional behaviors and skills. The aim of this study is to investigate student stress in response to programmatic changes wrought by the pandemic and whether stress impacted student self-reflection. Review of literature: Self-reflection is positively associated with growth of professional behavior and academic performance. Student level of self-reflection has been shown to be negatively impacted by stress. Subjects: A convenience sample of 35 students entering the program fall 2019 made up the participants. Methods: Outcome measures were collected six times over two academic years. The Self-Reflection Insight Scale (SRIS) consists of 20 statements rated on a 5-point Likert scale with 3 subscales: need for reflection (N), engaging in reflection (E), and insight (I), scoring from 10 to 100. The Perceived Stress Scale (PSS-10) is a 10-item questionnaire rated on a 4-point Likert scale, scoring from 0 to 40. Results: SRIS scores increased significantly from time 1 to 2, prior to the campus closure; no significant change for times 3 through 6. PSS scores indicated a higher percentage of students reporting a high level of stress at time 3 in the months after campus closure, decreasing significantly from time 3 to 4 during virtual/hybrid learning and increasing from time 5 to 6 as students prepared for clinical internship. No correlation was seen between SRIS and PSS, however a negative correlation was observed between SRIS subscale I and PSS at time 4 and 5. Discussion: Student perceived stress decreased during the study despite a universally stressful time. Student stress increased as students prepared for their first clinical internship experience, consistent with prior research. Initial gains in student self-reflection did not significantly change during the 1.5 years of the pandemic indicating that despite multiple academic and social challenges, students were able to maintain, but not grow, their level of professional self-reflection. Research is needed to further describe the relationship between stress and insight. Conclusion: The Program’s response to pandemic mandates may have positively influenced student stress

On the run for water - Root growth of two phreatophytes in the Taklamakan Desert

Desert phreatophytes require extremely fast root growth for a successful establishment We measured the speed of seedling root growth of two phreatophytic plant species, Alhagi sparsifolia and Karelinia caspia, which form dominant or codominant stands around the river oases at the southern fringe of the Taklamakan Desert. As A sparsifolia occurs at sites with deeper groundwater, we expected the roots of this species to reach down more rapidly than those of K caspia. Furthermore, we expected seedlings experiencing no irrigation and low fertilization to have deeper reaching roots than seedlings with irrigation and fertilization. Seeds of both species were sown into 1 and 2 m long tubes in a glasshouse and in a field experiment, respectively. After 16 weeks of growth in the field roots of K. caspia and A. sparsifolia reached down 2 2 m and 1.7 m, respectively. In accordance with a faster growth, K. caspia had a higher water use, which resulted in a faster decrease of water content in the tubes. Species differences in the vertical reach of roots in the glasshouse experiment were comparable to those in the field experiment After 12 weeks without irrigation, A sparsifolia had a higher rooting depth (0.45 m) than with irrigation (0 30 m), while root depths of K caspia showed the opposite pattern with 062 m and 0 72 m, respectively Fertilizing increased total biomass of both species, while low level of fertilization had the tendency to increase the root shoot ratio and the specific root lengths (SRL), most likely a response to acquire nutrients at lower costs. However, plants of K. caspia showed an increase in SLR already after 12 weeks, while it took 16 weeks for A sparsifolia to increase SRL in the low fertilization level. Our results show clearly that both species are able to reach the groundwater table in the river valleys (6 5 m) within a time span of five to six months after germination However, the encountered vegetation pattern is probably not caused by differences in the speed of rooting depth, but might be the result of a higher capability of growing up with sand accumulation of A sparsifolia. As additional irrigation and fertilization did not enhance rooting depth in both species, these factors will have little impact in restoration procedures (C) 2010 Elsevier Ltd All rights reserve

Effect of Helicobacter Pylori Eradication on Extent of Duodenal Gastric Metaplasia and Grade of Gastritis

The extent of the regression of duodenal gastric metaplasia (DGM) after the eradication of Helicobacter pylori infection is controversial. Therefore, we decided to assess the degree of DGM before, sex weeks and one year after H. pylori eradication. 105 consecutive Helicobacter pylori positive patients with endoscopically proven duodenal ulcer, with DGM and Helicobacter pylori infection were recruited for this study. The diagnosis of Helicobacter pylori infection was based on CLO-test and histology, and DGM was assessed on four bulb biopsies taken before, sex weeks and one year after Helicobacter pylori eradication. Histological assessment of Helicobacter pylori associated gastritis was performed according to the Sydney classification. Follow up study on 98 patients before, six weeks and one year after the eradication of Helicobacter pylori showed that the mean extent of DGM did not change significantly after eradication and did not differ when compared with 14 patients with persisting infection. Our results show that the inflammatory process related to Helicobacter pylori does not play the main role in the development of DGM

Geographic Distribution of Childbirth among Adolescents in Cameroon from 2003 to 2005

Objective. To determine the frequency and the trend of adolescents (10–19 years) in childbirth within a period of 3 years in referral maternity units in Cameroon. Method. Descriptive and retrospective study for a 3-year period (2003–2005) in referral maternity units headed by a qualified Obstetrician-Gynecologist. We analyzed the trend and geographic distribution of 8222 adolescent deliveries over 3 years. Epi Info 3.5 software was used for data analysis. Chi square test for trend was used to assess the contribution of adolescent deliveries over years. The trend was considered significant if P < .05. Results. During the period of the study, there was a total of 8387 deliveries. We excluded 165 women because of lack of information about age. We therefore included a total of 8222 adolescent deliveries. Overall, the contribution of adolescents to deliveries ranged from 6.87% to 26.51%, depending on the region with a national mean of 14.23%. Adolescents aged 16 or less contributed to 2.82% of deliveries while those aged from 17 to 19 contributed to 11.41%. The contribution of adolescents to deliveries decreased significantly over 3 years (P < .0001). Conclusion. The study underscores the importance of Public Health programs in strengthening maternity services for adolescents in Cameroon while taking into consideration geographic differences

Anemia in patients on chronic hemodialysis in Cameroon: prevalence, characteristics and management in low resources setting

Background: Anemia is a common complication of chronic kidney disease. We investigated the prevalence, characteristics and management of anemia in patients on chronic hemodialysis and assessed the response to blood-transfusion based management in Cameroon.Methods: This was a cohort study of five months’ duration (August-December 2008) conducted at the Yaoundé General Hospital’s hemodialysis center, involving 95 patients (67 men, 70.5%) on chronic hemodialysis by a native arterio-venous fistula. A monthly evaluation included full blood counts, number of pints of red cell concentrates transfused, and vital status.Results: At baseline, 75 (79%) patients had anemia which was microcytic and hypochromic in 32 (43%). Anemia was corrected in 67 (70.5%) patients using blood transfusion only, while 28 (29.5%) patients were receiving erythropoietin (11 regularly, 39%). Only 77.2% of 342 pints (median 3.0, range 0-17 per patients) of red cell concentrates prescribed were effectively received during the follow-up at an unacceptably high cost to patients and families. Mean hemoglobin and mean corpuscular hemoglobin levels remained stable during follow-up, while mean corpuscular volume increased. Erythropoietin treatment was the main determinant of favorable trajectories of hematological markers.Conclusions: Patients on chronic hemodialysis have predominantly microcytic hypochromic anemia, with limited capacity for correction using blood transfusion.Key words: Anemia; Blood transfusion; End stage renal disease; Hemodialysis; Sub-Saharan Afric

Using mixed methods for analysing culture : The Cultural Capital and Social Exclusion project

This paper discusses the use of material generated in a mixed method investigation into cultural tastes and practices, conducted in Britain from 2003 to 2006, which employed a survey, focus groups and household interviews. The study analysed the patterning of cultural life across a number of fields, enhancing the empirical and methodological template provided by Bourdieu’s Distinction. Here we discuss criticisms of Bourdieu emerging from subsequent studies of class, culture and taste, outline the arguments related to the use of mixed methods and present illustrative results from the analysis of these different types of data. We discuss how the combination of quantitative and qualitative methods informed our analysis of cultural life in contemporary Britain. No single method was able to shed light on all aspects of our inquiry, lending support to the view that mixing methods is the most productive strategy for the investigation of complex social phenomena

The Effect of Cosmological Background Dynamics on the Spherical Collapse in MOND

The effect of background dynamics of the universe on formation of large scale structures in the framework of Modified Newtonian Dynamics (MOND) is investigated. A spherical collapse model is used for modeling the formation of the structures. This study is done in two extreme cases: ({\it i}) assuming a universe with a low-density baryonic matter without any cold dark matter and dark energy; ({\it ii}) a dark energy dominated universe with baryonic matter, without cold dark matter. We show that for the case ({\it ii}) the structures virialize at lower redshifts with larger radii compared to the low-density background universe. The dark energy slow downs the collapse of the structures. We show that our results are compatible with recent simulations of the structure formation in MOND.Comment: 16 pages, 4 Figures, accepted by New Astronom

An ecological approach to problems of Dark Energy, Dark Matter, MOND and Neutrinos

Modern astronomical data on galaxy and cosmological scales have revealed powerfully the existence of certain dark sectors of fundamental physics, i.e., existence of particles and fields outside the standard models and inaccessible by current experiments. Various approaches are taken to modify/extend the standard models. Generic theories introduce multiple de-coupled fields A, B, C, each responsible for the effects of DM (cold supersymmetric particles), DE (Dark Energy) effect, and MG (Modified Gravity) effect respectively. Some theories use adopt vanilla combinations like AB, BC, or CA, and assume A, B, C belong to decoupled sectors of physics. MOND-like MG and Cold DM are often taken as opposite frameworks, e.g. in the debate around the Bullet Cluster. Here we argue that these ad hoc divisions of sectors miss important clues from the data. The data actually suggest that the physics of all dark sectors is likely linked together by a self-interacting oscillating field, which governs a chameleon-like dark fluid, appearing as DM, DE and MG in different settings. It is timely to consider an interdisciplinary approach across all semantic boundaries of dark sectors, treating the dark stress as one identity, hence accounts for several "coincidences" naturally.Comment: 12p, Proceedings to the 6-th Int.

Metabolic Syndrome X – High Risk Factor for Acute Myocardial Infarction and Its Complications

Metabolic Syndrome X is a clinical entity which comprises the following factors: diabetes mellitus, arterial hypertension, high levels of triglyceride and/or low levels of HDL cholesterol, central obesity and microalbuminuria (by WHO criteria). The first goal of this study was to determine the frequency of the Metabolic Syndrome X (MSX) in patients with acute myocardial infarction compared with the general population. The second goal of the study was to examine the frequency of heart failure and reinfarction rate in the patients with myocardial infarction, with and without MSX. Furthermore, the relationship between gender and MSX was analyzed. A total of 101 patients with acute myocardial infarction took part in randomized trial (32 women and 69 men). MSX and all of its components were diagnosed according to WHO criteria. To determine statistical significance of our results, we used 2 test and t-test for independent samples. From 101 patient 48 had MSX (47.52%), while in the general population incidence of MSX is 3–4%. The reinfarction and the heart failure rate were significantly higher in the group of patients with MSX (p = 0.0067 and p = 0.0217, respectively ). To conclude, the results of the present study confirm that MSX is a high risk factor for myocardial infarction and its complications
