The Patient–Therapist Relationship: Beliefs That Shape Care

Field: Health Professions (Health Sciences)

Abstract The results of a previous inquiry suggest that three images of occupational therapists dominate patients’ stories about them: the images of technician, parent, and collaborator or friend. These ways of being in practice can be said to reflect the various understandings that therapists have about how to enact the profession’s commitment to both competence and caring. When therapists act as technicians or authoritarian parents, patients register their disappointment over a valuation of competence that excludes caring actions. In a more current inquiry into the climate of caring, patients and caregivers reflect about the current health care system and identify three societal constructs that shape a preference for competence over caring: (a) emphasis on the rational fixing of the health care problem, (b) overreliance on methods and protocols, and (c) a health care system driven by business, efficiency, and profit. Occupational therapists who are concerned about complaints that the health care system is increasingly uncaring might benefit from a consideration of the extent to which societal beliefs shape the manner in which they care.
Bloodstream and central line isolates from hematopoietic stem cell transplant recipients: data from a developing country

Field: Medicine (Health Sciences)

Abstract Introduction Bloodstream infections ( BSI s) and central line infections remain among the major causes of morbidity and mortality in transplant recipients because of prolonged neutropenia and mucosal damage. The objective of this study was to determine the frequency and outcome of bacterial and fungal isolates from patients undergoing allogeneic hematopoietic stem cell transplant. Materials and methods This study was conducted at the Aga Khan University and Hospital's bone marrow transplant unit. All patients who underwent an allogeneic stem cell transplant with matched sibling/parent donor were included. The study period ranged from April 2004 to December 2012. Transplantation was performed according to institutional protocols. All patients were admitted in single rooms with positive pressure and high‐efficiency particulate air filters. Ciprofloxacin, fluconazole, and valaciclovir were used for standard prophylaxis, which was started at the time of conditioning. All blood cultures were obtained at clinical suspicion of systemic infection, mainly documented as fever (temperature of >38.5°C). BSI s and line infections were defined as isolation of bacterial or fungal pathogen from at least one blood/central line culture. Results In total, 101 of 108 patients developed febrile neutropenia. In the 101 patients, 245 documented febrile episodes occurred. There were 40 culture‐positive episodes and 205 culture‐negative episodes. Of these 40 culture‐positive episodes, 22 patients had bloodstream isolates and 18 had central line isolates. The median ± standard deviation time of febrile neutropenia was day 7 ± 2 days (range: day −3 to day +13). The most common bloodstream isolate was Escherichia coli ( n = 9) followed by S taphylococcus epidermidis ( n = 5). One patient developed F usarium infection. In central line infections, S . epidermidis was the most common organism ( n = 8). In 2 patients with central venous catheters, C andida albicans was the isolate. Transplant‐related mortality from sepsis occurred in 9.2%. Conclusion E . coli was mainly responsible for BSI , while gram‐positive organisms dominated catheter‐related febrile episodes. Transplant‐related mortality due to sepsis was 9%.
Estimating the long-term residual value of zinc oxide for growing wheat in a sandy duplex soil

Field: Agricultural and Biological Sciences (Life Sciences)

A long-term (17-year duration) field experiment was started on newly cleared zinc (Zn)-deficient sandy duplex soil (sand with lateritic ironstone gravel over clay) in south-western Australia that had never been fertilised to measure the residual value of Zn oxide for growing spring wheat (Triticum aestivum L.). When wheat was grown in the field experiment different amounts of Zn were applied once only to plots in 1983, 1984, 1986, 1990, 1992, 1996, 1997, and 2000. When the field experiment was terminated, we collected soil samples from the top 0.10 m of the field plots to do a glasshouse experiment reported here. In the pot experiment 5 amounts of Zn were applied to subsamples of soil collected from each plot of the field experiment. When a yield increase (response) to the freshly applied Zn was obtained in the pot study the maximum yield plateau for the relationship between yield of 54-day-old dried wheat shoots and the amount of Zn freshly applied was similar regardless of when and how much Zn was applied in the field. The amount of Zn freshly applied to soil in the pots required to produce 90% of the maximum yield of dried wheat shoots was determined for soil previously treated with no Zn or different amounts of Zn in different years in the field to provide DM90 values. The DM90 values were largest when no Zn was applied in the field, decreased as more Zn was applied in the field and, for each amount of Zn applied in the field, increased as the number of years from application of Zn increased. For soil treated with 0.5 and 1.0 kg Zn/ha in the field the relationship between DM90 values and the number of years since Zn was applied in the field was approximately linear. The projected number of years taken for soil previously treated with Zn in the field to require the same DM90 values as soil samples collected from the nil-Zn treatments in the field was 23 and 40 years for the 0.5 and 1.0 kg Zn/ha treatments, respectively. In the pot experiment the Zn concentration in plant parts that was related to 90% of the total yield of dried wheat shoots (critical Zn concentration) was ~12 mg/kg for youngest mature growth (YMG) and 22 mg/kg for rest of shoots (ROS). The relationship between yield of dried wheat shoots and DTPA soil test Zn before sowing was similar for all the Zn treatments applied in both the field and pot studies, and the critical value was ~0.17 mg Zn/kg soil.
Trap Behavior of the Optical Power Fluctuation in AlGaN-Based UV-C LEDs Degradation

Field: Materials Science (Physical Sciences)

The trap behavior of the optical power (OP) fluctuation in the degradation of deep ultraviolet light-emitting diodes (DUV-LEDs) is investigated in this work. The OP fluctuation under current stress is related to the combined action of acceptor activation, migration, and recombination. After stress, the changes observed in the admittance spectroscopy and deep-level transient spectroscopy measurements are due to a reduction in electron traps at ${E}_{c}$ –20 meV ( ${E}_{{1}}$ ) and increases in electron traps at ${E}_{c}$ –0.5 eV ( ${E}_{{2}}$ ), 0.68–0.79 eV ( ${E}_{{3}}$ ), and 0.95–1.2 eV ( ${E}_{{4}}$ ). The electron trap ${E}_{{1}}$ , located at the active region interface, has a prominent proportion in the apparent charge distribution profile and recombines with holes to restrict their entry into the quantum wells. The other traps contribute to an increase in the leakage current and nonradiative recombination. Reduction of the interface traps would weaken the hole transport shielding effect, but the hole injection augmentation would be wasted in the nonradiative recombination centers when defects are greatly generated in the active region during the long-term operation. Our study dissects the complex mechanisms in the electrical stress-induced degradation of DUV-LEDs and provides a constructive perspective on fabricating high-reliability AlGaN-based devices.
New Validated Method for the Determination of Memantine Hydrochloride Content in Tablet Dosage Forms by a High Performance Liquid Chromatography with Evaporative Light Scattering Detector

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

The aim of the present work was to develop and validate a liquid chromatographic method for the determination of memantine hydrochloride in tablet dosage form. Chromatographic separation was achieved on a intersil ODS 3v column (150×4.6 mm), 5 μm column with a HPLC grade methanol and 0.1% trifluroacetic acid buffer in the ratio of 50:50 (v/v/v) as mobile phase under ELS Detector conditions like a evaporation temperature 70°C, nebulization temperature 40°C, nitrogen flow rate 1.2SLM, and LED intensity 90%, injection volume is 20μL, flow rate is 1.0 mL/min and the expected retention of memantine hydrochloride peak is about 6.8 minutes. Response was a linear function of concentration in the range 2–0.01 μg/mL for memantine hydrochloride; correlation coefficiencent was 0.9998, respectively. LOD and LOQ for memantine hydrochloride were found 0.01 μg/mL and 0.03 μg/mL based on signal to noise ratio(S/N). Accuracy (recoveries 88–96%) and reproducibility were found to satisfactory. The present method can be applied successfully for the quantification of active pharmaceutical ingredient content in the combined formulations of memantine hydrochloride.

[Roles of calcium ion channels and its clinical significance in sperm motility].

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

As an important intracellular messenger, Ca2+ plays a major role in sperm motility. In spermatozoa, multiple Ca2(+)-permeable channels have been identified in the plasma membrane of mammalian sperm, including voltage-gated Ca2+ channels (Cav channels), cyclic nucleotide-gated channels (CNGC), cation channels of sperm (CatSper) and the transient receptor potential (TRP) family. As calcium regulation of sperm motility is mainly mediated by these calcium channels, any aberration of the channels can lead to the decline of sperm activities. Recent progress in the researches on the relationship between sperm motility and calcium-related ion channels is briefly reviewed in this article.

National Population Programme 1989-1994. [Summary].

Field: Social Sciences (Social Sciences)

Mexico's National Population Program, 1989-1994, offers the following specific objectives: to promote a better rhythm of population growth be reducing the fertility level (to a growth rate of 1.8% in 1994 and to 1% in 2000), improving population welfare and increasing life expectancy; to achieve a population distribution according to the development potential of the different regions, with consideration of national and international migration, with the hope of lessening the size of the great metropolitan zones and encouraging the growth of small and intermediate cities; to promote the development and welfare of indigenous groups, considering their demographic structure and dynamics, and respecting their ethnic identity; to promote the integration of demographic objectives into the country's economic and social planning, particularly to improve the well-being of those living in extreme poverty; to promote women's participation, in conditions equal to those of men, in economic, political, social, and cultural life, to contribute to the achievement of a better level of individual, family, and community well-being. The priorities established: to promote the reduction of fertility through population education and family planning services; to establish demographic objectives to guide regional development and the development of urban centers to reorient migration flows as required; to support family participation in population policy objectives; to increase women's educational level; to analyze mortality and morbidity trends; to analyze the demographic behavior of the indigenous population to facilitate actions taken to fulfill their needs and preserve their identity; and to balance population actions with other actions taken to assist disadvantaged rural and urban groups. The strategy for implementation: the integration of population policy into development policy; decentralization to the state and municipal levels; coordinating the activities in various sectors (health, education, housing); enhancement of community participation; development of information and research activities and of human resources and strengthening of population education and communication activities.

IDDF2020-ABS-0154 Factors associated with failed non-operative reduction of intussusception in children

Field: Medicine (Health Sciences)

Background

The non-operative method of reduction is the gold standard treatment for intussusception in children. The successful non-operative reduction of intussusception carries less morbidity and mortality, but the literature on the risk factors for failed intussusception reduction is scarce. Hence a study was conducted to evaluate the factors associated with the failure of non-operative reduction of intussusception in children.

Methods

A retrospective study was conducted in a Paediatric Surgery hospital, which included children admitted with intussusception between November 2013 and February 2020.

Results

A total of 106 (67%) children underwent pneumatic reduction. Eighty-nine (84%) children had a successful reduction. Fourteen (13%) children with failed reduction underwent laparotomy. Twelve of these fourteen children had to undergo bowel resection (seven gangrene and five lead points) and the rest two had a successful operative reduction. Two (2%) children with perforation following reduction, a child (1%) each with doubtful reduction and doubtful pneumoperitoneum underwent surgery. Seven (8%) of 89 successful reductions had a recurrence. The management of these children is depicted in figure 1. A higher rate of failed reduction was found in children who presented at or after 48 hours of the onset of symptoms (p-0.03) and abdominal distension at presentation (p<0.002). On multiple logistic regression analysis, the children presenting at or after 48 hours onset of symptoms (OR: 11.3/p-0.039) and abdominal distension at presentation (OR: 4.46/p-0.021) were found to be associated with increased risk of failure of non-operative reduction. The variables age <1 year (OR:0.466/p-0.165), weight <10 kg (OR: 1.641/p-0.468), pain abdomen (OR: 1/p-0.99), vomiting (OR: 0.562/p-0.39), bilious vomiting (OR: 6.75/p-0.136), fever (OR: 2.23/p-0.357), bleeding per rectum (OR: 2.55/p-0.162), and palpable mass (OR: 2.74/p-0.135) were not associated with the failed non-operative reduction.

Conclusions

The risk factors for failed non-operative reduction of intussusception include a presentation at or after 48 hours of the onset of symptoms and the presence of abdominal distension at presentation.
Perception of the envelope-beat frequency of inharmonic complex temporal envelopes

Field: Psychology (Social Sciences)

Listeners can hear slow sinusoidal variations in the depth of sinusoidally amplitude-modulated (SAM) stimuli. Here, the SAM stimulus of frequency fm acts as the carrier, and the slow variation in depth of frequency fm′ (referred to as “second-order” amplitude modulation) corresponds to a beat in the temporal envelope. Recent studies have suggested that second-order amplitude modulation perception is based on a modulation-distortion component or the “venelope” (the Hilbert envelope of the ac-coupled Hilbert envelope), both occurring at the envelope-beat frequency fm′. This was tested by transposing to the modulation domain the matching paradigm used by Schouten et al. [J. Acoust. Soc. Am. 34, 1418–1424 (1962)]. Listeners estimated the envelope-beat frequency evoked by a 5-Hz, second-order SAM white noise with fm either an integer multiple of fm′ or shifted in frequency to make the complex envelope inharmonic. The results indicate that the perception of the envelope-beat frequency was affected by these shifts when fm⩽20Hz. This suggests that, at least at low modulation frequencies, the perceived envelope beat is not determined by a modulation-distortion or venelope component, but rather relies on the time intervals between the main peaks of the first-order envelope.
Predicting Premorbid Ability in African American Elders: Using Demographic and Performance Variables

Field: Psychology (Social Sciences)

Researchers and clinicians require a method of estimating an elderly individual's premorbid ability level in order to determine the amount of cognitive decline that has occurred. This issue has received a great deal of attention within the research literature; however, little attention has been paid to this issue specifically in elderly African American elderly adults. Although researchers have examined the predictive utility of demographic variables, few studies have examined whether including additional demographic variables (i.e., quality of education) improves prediction of premorbid ability. The current sample consisted of 46 African American elderly adults who did not exhibit any cognitive impairment or neurological disorders. Using correlation analysis a number of significant relationships were found between quality and type of education variables and full scale IQ scores. Although, results suggest that including some quality of education variables may slightly improve the ability to predict premorbid ability in African American elders, reading level emerged as the strongest predictor of full-scale IQ. Limitations of the current study and directions for future research are discussed.
Clinical Experiences with 4-Hydroxycoumarin Anticoagulant No. 63 and the Antagonistic Effect of Menadione and Vitamin K 1

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

The successful use of dicumarol in the prevention of intravascular thrombosis and subsequent embolism has led to the investigation of other coumarin compounds as therapeutic anticoagulants. 4-Hydroxycoumain anticoagulant No. 63 is such a compound. Like dicumarol, it induces hypoprothrombinemia and daily tests of prothrombin time are necessary as a guide to dosage. Our experience indicates that a less fluctuating and somewhat more consistent therapeutic hypoprothrombinemia can be established and maintained with anticoagulant No. 63 than with dicumarol. The potential disadvantage of the prolonged hypoprothrombinemia after administration is stopped is counter balanced by the strong and relatively rapid antagonistic effect of vitamin K 1 .
