Is Compressed and Limited Synchronous Delivery of Anatomy Content in a Hybrid Delivery Format Effective in Transitional OT Student Learning?
Hybrid occupational therapy (OT) students transitioning from certified OT assistants (COTAs) to OTs can successfully learn graduate-level anatomy in a compressed format with limited synchronous instruction time. The effectiveness of a human anatomy course with limited synchronous instruction time for transitional hybrid occupational therapy students was investigated. A retrospective, non-randomized study was used. A university graduate level human anatomy course for transitional OT students used prosected (previously dissected) cadavers. Students (n=46, 32 instruction hours over 16 weeks) final anatomy course grades for three cohorts were measured retrospectively. There was a 98% first-time pass rate and 100% second time pass rate. Less than 5% of the students needed to either repeat the course (one student) or withdrew from the course prior to course completion (one student). Results suggest that a hybrid learning model with limited synchronous instruction time is effective for transitional OT students learning human anatomy. Programs should consider how instruction time and distribution impacts anatomy learners, and when there is limited time in the classroom, investigate alternative pedagogies for those few students who would benefit from a more immersive-learning environment. Anatomy knowledge is essential in progressing through occupational therapy curriculums and is needed for client management. Understanding what factors impact learning anatomy could assist in creating more effective anatomy courses for occupational therapy students
Pets or Pest: Peritoneal Dialysis-related Peritonitis due to Pasteurella multocida
Pasteurella multocida is a Gram-negative bacteria found in the oropharynx of many domestic animals. P. multocida can cause a variety of human infections, but it remains a rare cause of peritoneal dialysis-related peritonitis. We describe a severe case of peritoneal dialysis-related peritonitis due to P. multocida infection caused by close contact with a cat
El estado actual de la investigación sobre la congruencia persona-ambiente. Propuesta de aplicación de un diseño experimental
En el presente trabajo se hace una revisión del estado actual de la investigación sobre
la congruencia persona-ambiente, analizando los principales problemas conceptuales
y metodológicos que existen en esta línea de investigación, así como las críticas que
recibe uno de los modelos más representativos del momento: el modelo de la elección
vocacional de Holland. Según este autor, los individuos suelen elegir profesiones que
son congruentes con sus características personales, y este ajuste tiene repercusiones
positivas tanto para el rendimiento como para la satisfacción en el trabajo. Además,
existen otros modelos que han sido propuestos desde diferentes perspectivas (el estrés
laboral, socialización laboral, ajuste laboral...). Teniendo en cuenta los inconvenientes
que presentan la mayoría de los estudios empíricos realizados, se plantea la posibilidad
de abordar el tema desde el paradigma experimental sugiriendo un diseño que permite
solventar, o al menos minimizar, dichos problemas.The aim of this paper is to review the present state of the person-environment
congruence research. We analyze the main conceptual and methodological problems
that this research have and the cristicisms that one of the most representative model
receives: Holland’s vocational choices model. This author suggests that the individuals
tend to choose occupations that are congruent with their personal characteristics, and
that this fi t (or adjustment) has positive implications both for the performance and job satisfaction. On the other hand, models from other approaches have also been proposed
(work stress, work socialization, laboral fi t (or adjustment...). Taking into account the
inconvenients that most of these kind of studies have, the possibility of start on this
subject from an experimental paradigm suggesting a design that may solve or reduce
these problems is proposed
Femoral Neck Fracture Management in the Young Patient: A Case Review
Introduction:The optimal management of femoral neck fractures in the young patient remains controversial. Although there are universally accepted principles, there remains some variability in the optimal timing of surgery and method of fixation. In general, surgery should be performed on an urgent or emergent basis when feasible to decrease peri-operative complications, length of stay, and most importantly the ultimate likelihood of avascular necrosis. However, it is important to note that the preference toward a specific method of fixation remains heterogeneous among orthopedic surgeons.(1)
The purpose of this study is to present our preferred technique for treatment of displaced femoral neck fractures in the young patient. We utilize a two-incision technique. First, an anterior approach (Smith-Peterson) to obtain an anatomic reduction, and a direct lateral approach for the definitive fixation using the Synthes Femoral Neck System (FNS). This technique for open reduction internal fixation (ORIF) is part of a larger case series that reports in more detail on specific outcomes and potential complications that once can expect when treating femoral neck fractures in young individuals. This is a case of a 39-year-old male who fell while playing soccer.
Materials and Methods: Inclusion Criteria: Our criteria includes all patients 50 years old and younger who are admitted and treated for displaced femoral neck fractures, diagnosed by x-ray and CT. All patient were treated by the senior authors, Dr. Frank Gerold or Dr. Michael Lago at the University of Texas Rio Grande Valley in affiliated hospitals. Additionally, the population of study includes mainly Hispanic, non-English speaking patients reflecting the demographics of the Rio Grande Valley. All patients in the study have were treated with ORIF as described above.
Surgical Technique and Post-operative Protocol
The surgical approach for reduction was the anterior Smith-Peterson approach and technique of internal fixation was via with the Synthes FNS. The patient is placed in the supine position on a fracture table with the leg draped free. A skin incision is made beginning 1 cm distal and lateral to the anterior inferior iliac spine (AIIS). The interval between sartorius and tensor fascia latae (TFL) is developed. The lateral femoral cutaneous nerve (LFCN) is identified and carefully retracted medially with sartorius. The tendinous portion of rectus femoris is identified and elevated off the hip capsule. The hip capsule is then opened to expose the femoral neck. Reduction is achieved with bone reduction forceps. A large threaded K-wire can be used a joystick when placed in the proximal fragment to aid in reduction. Provisional fixation is obtained with smooth K-wires and definitive fixation is performed through a small lateral incision, typically less than 5 cm. Post operatively the patient is made non weight-bearing (NWB) for 6 weeks and transition to weight-bearing as tolerated (WBAT) thereafter.
Discussion: The patient went on to achieve union at 4 months post-op as evidence of imaging and clinical functional status. After use of this technique by mentioned surgeons over a span of 2 years, only one complication occurred. Avascular necrosis (AVN) was noted in one patient during follow up; however, patient had comorbidities including mental disability, which could have affected adherence to post operative weight-bearing restrictions.
Treatment options for displaced proximal femoral fractures include closed reduction percutaneous pinning (CRPP), open reduction and internal fixation (ORIF), Hemiarthroplasty (HA), or total hip arthroplasty (THA). Selection of the appropriate implant for a particular patient requires individualized assessment of patient-related (eg, growth potential, activity level, life expectancy, and medical comorbidities) and fracture-related (eg, location, orientation, comminution) factors.
Traditionally implant choice in an open procedure for otherwise healthy active individuals has been between cannulated screws and sliding hip screw.(1) While both implant choices have unique advantages and disadvantages to one another, there remains no substantial evidence to recommend a particular implant or approach.(2-3) This has led to a heterogeneity in techniques and implant uses. Newer constructs such as the Synthes Femoral Neck System (FNS) build on the strengths of traditional methods of fixation, such as cannulated screws and the sliding hip screw, to allow for controlled compression of the fracture while achieving greater rotational stability to decrease the rate of failure and increase union rates.
Conclusion: In our case series, ORIF with the use of the Synthes Femoral Neck System for displaced femoral neck fractures and led to excellent outcomes with a low rate of complication. We recommend this technique as another option, particularly when taking care of the younger, more active sub-population. We strongly believe that anatomic reduction at time of fixation, which can be only achieved though an open approach, is the single most important factor in the decision-making algorithm for the treatment of proximal femoral fractures in the younger population
Establishing Baseline Nutrient and Sediment Input in the Lower Cache River Watershed, AR
Contaminants in waterways continue to be a problem especially in watersheds dominated by land use changes such as agriculture. Clearing the land for agricultural use is needed to support the population; however, agricultural contaminants are cited as contributing the greatest input of suspended solids and nutrients to waterways. Quantifying various contaminants in surface water is useful in determining their origin, thus aiding in their mitigation. This study, focused on the Cache River Watershed, reports pH, dissolved oxygen (DO), conductivity, turbidity, total suspended solids (TSS), NO3 - , NO2 - , and PO4 3- in the lower sub watersheds. It was determined that in the Cache River, at these particular sites, TSS, NO3 - , NO2 - , and PO4 3- concentrations differ due to varying sources of input and land use
Disgust implicated in obsessive-compulsive disorder
Psychiatric classificatory systems consider obsessions and compulsions as forms of anxiety disorder. However, the neurology of diseases associated with obsessive-compulsive symptoms suggests the involvement of fronto-striatal regions likely to be involved in the mediation of the emotion of disgust, suggesting that dysfunctions of disgust should be considered alongside anxiety in the pathogenesis of obsessive-compulsive behaviours. We therefore tested recognition of facial expressions of basic emotions (including disgust) by groups of participants with obsessive-compulsive disorder (OCD) and with Gilles de la Tourette's syndrome (GTS) with and without co-present obsessive-compulsive behaviours (GTS with OCB; GTS without OCB). A group of people suffering from panic disorder and generalized anxiety were also included in the study. Both groups with obsessive-compulsive symptoms (OCD; GTS with OCB) showed impaired recognition of facial expressions of disgust. Such problems were not evident in participants with panic disorder and generalized anxiety, or for participants with GTS without obsessions or compulsions, indicating that the deficit is closely related to the presence of obsessive-compulsive symptoms. Participants with OCD were able to assign words to emotion categories without difficulty, showing that their problem with disgust is linked to a failure to recognize this emotion in others and not a comprehension or response criterion effect. Impaired recognition of disgust is consistent with the neurology of OCD and with the idea that abnormal experience of disgust may be involved in the genesis of obsessions and compulsions
Equatorial restriction of the photoinduced Jahn–Teller switch in Mn(iii)-cyclam complexes
Ultrafast transient absorption spectra were recorded for solutions of [MnIII(cyclam)(H2O)(OTf)][OTf]2 (cyclam = 1,4,8,11-tetraazacyclotetradecane and OTf = trifluoromethanesulfonate) in water to explore the possibility to restrict the equatorial expansion following photoexcitation of the dxy ← dz2 electronic transition, often resulting in a switch from axial to equatorial Jahn–Teller distortion in MnIII complexes. Strong oscillations were observed in the excited state absorption signal and were attributed to an excited state wavepacket. The structural rigidity of the cyclam ligand causes a complex reaction coordinate with frequencies of 333, 368, 454 and 517 cm−1, and a significantly shorter compressed-state lifetime compared to other MnIII complexes with less restricted equatorial ligands. Complementary density functional theory quantum chemistry calculations indicate a switch from an axially elongated to a compressed structure in the first excited quintet state Q1, which is accompanied by a modulation of the axial tilt angle. Computed harmonic frequencies for the axial stretching mode (∼379 cm−1) and the equatorial expansions (∼410 and 503 cm−1) of the Q1 state agree well with the observed coherences and indicate that the axial bond length contraction is significantly larger than the equatorial expansion, which implies a successful restriction of the wavepacket motion. The weak oscillation observed around 517 cm−1 is assigned to a see-saw motion of the axial tilt (predicted ∼610 cm−1). The results provide insights into the structural perturbations to the molecular evolution along excited state potential energy surfaces of MnIII octahedral complexes and can be used to guide the synthesis of optically controlled MnIII-based single-molecule magnets
The impact of mixed emotions on judgements: a naturalistic study during the FIFA world cup
Experiencing mixed emotions, a combination of two oppositely-valenced emotions, has been shown to reduce bias in decision making and improve the accuracy of judgements made. However, most previous research has been limited to laboratory-based experiments. In this pre-registered study, we looked at mixed emotions and judgements in the naturalistic context of watching sport during the FIFA world cup. N = 80 participants reported on mixed emotions before and after each England game during the World Cup, and made score predictions for each game, collecting a total of k = 480 observations. We used a lagged-effect design and multilevel modelling to analyse the data. We found that participants who felt more mixed emotions at the end of a match made significantly more likely score predictions in the following match, indicating that experiencing stronger mixed emotions subsequently predicted more reasonable judgements. This result was supported even after controlling for a number of affective, attitudinal, and socio-demographic variables. This provides evidence that naturally occurring mixed emotions are related to improved real-world judgements. The evidence is discussed through the lens of fantasy realisation theory, and the importance of feeling mixed during decisions involving puzzling or uncertain outcomes is emphasised
Therapeutic approach in glioblastoma multiforme with primitive neuroectodermal tumor components: case report and review of the literature
Glioblastoma multiforme (GBM) is the most common and aggressive malignant glioma that is treated with first-line therapy, using surgical resection followed by local radiotherapy and concomitant/adjuvant temozolomide (TMZ) treatment. GBM is characterised by a high local recurrence rate and a low response to therapy. Primitive neuroectodermal tumour (PNET) of the brain revealed a low local recurrence rate; however, it also exhibited a high risk of cerebrospinal fluid (CSF) dissemination. PNET is treated with surgery followed by craniospinal irradiation (CSI) and platinum-based chemotherapy in order to prevent CSF dissemination. GBM with PNET-like components (GBM/PNET) is an emerging variant of GBM, characterised by a PNET-like clinical behaviour with an increased risk of CSF dissemination; it also may benefit from platinum-based chemotherapy upfront or following failure of GBM therapy. The results presented regarding the management of GBM/PNET are based on case reports or case series, so a standard therapeutic approach for GBM/PNET is not defined, constituing a challenging diagnostic and therapeutic dilemma. In this report, a case of a recurrent GBM/PNET treated with surgical resection and radiochemotherapy as Stupp protocol, and successive platinum-based chemotherapy due to the development of leptomeningeal dissemintation and an extracranial metastasis, is discussed. A review of the main papers regarding this rare GBM variant and its therapeutic approach are also reported. In conclusion, GBM/PNET should be treated with a multimodal approach including surgery, chemoradiotherapy, and/or the early introduction of CSI and platinum-based chemotherapy upfront or at recurrence
