RESUMO

This paper describes the development and psychometric evaluation of a brief self-report measure (BEACON) to inform universal mental health screening in schools. Items assess symptoms and impairment associated with anxiety and attention/hyperactivity problems (grades 4-11) as well as depression and eating difficulties (grades 6-11), with optional items for suicidality and self-harm (grades 7-11). Initial item examination based on Item Response Theory (IRT) and classical test theory involved 3844 students in grades 4 through 11 (Study 1) and identified 18 items for grades 4-5 and 31 items for grades 6-11 that fulfilled pre-set criteria. Study 2 extended testing with 10,479 students in grades 4-11 and added an additional four items assessing impairment associated with eating difficulties for older students (grades 6-11) creating a total of 35 items for grades 6-11. All items, for both grade-level versions, met the pre-set criteria for IRT and classical test theory analysis supporting their strength in the measurement of the dimensions of concern. The measure showed good reliability (subscale alphas .87 to .95). Validity was also demonstrated against standard symptom measures, school grades, school absenteeism, and help-seeking. The BEACON appears to be a psychometrically sound measure to use in the first stage of school-based screening for mental health problems.

RESUMO

Gaming the system, a behavior in which learners exploit a system's properties to make progress while avoiding learning, has frequently been shown to be associated with lower learning. However, when we applied a previously validated gaming detector across conditions in experiments with an algebra tutor, the detected gaming was not associated with reduced learning, challenging its validity in our study context. Our exploratory data analysis suggested that varying contextual factors across and within conditions contributed to this lack of association. We present a new approach, latent variable-based gaming detection (LV-GD), that controls for contextual factors and more robustly estimates student-level latent gaming tendencies. In LV-GD, a student is estimated as having a high gaming tendency if the student is detected to game more than the expected level of the population given the context. LV-GD applies a statistical model on top of an existing action-level gaming detector developed based on a typical human labeling process, without additional labeling effort. Across three datasets, we find that LV-GD consistently outperformed the original detector in validity measured by association between gaming and learning as well as reliability. LV-GD also afforded high practical utility: it more accurately revealed intervention effects on gaming, revealed a correlation between gaming and perceived competence in math and helped understand productive detected gaming behaviors. Our approach is not only useful for others wanting a cost-effective way to adapt a gaming detector to their context but is also generally applicable in creating robust behavioral measures.

RESUMO

OBJECTIVES: To conduct an exploratory analysis comparing in-person vs. virtual training programs about contraceptive care among clinicians and staff at 14 healthcare agencies in Washington state. METHODS: Survey data from in-person trainings were collected between July 2019 and March 2020 and from virtual trainings between June 2020 and January 2021. PRIMARY OUTCOMES: changes in contraceptive knowledge, understanding of contraceptive counseling and care, and participant engagement and experience with the training. RESULTS: Post-survey response rates for in-person trainings were 82% for clinicians and 72% for support staff while post-survey response rates for virtual trainings were 48% for clinicians and 43% for staff. Average knowledge scores for in-person clinician trainings increased from 63% prior to training to 80% post-training (p < 0.05), knowledge scores for virtual clinician trainings increased from 72% to 86% (p < 0.05), and the pre-to-post change in scores between training modalities was similar (p > 0.05 for the score difference). Average knowledge scores among in-person support staff trainings increased from 63% to 84% (p < 0.05), scores among virtual support staff trainings increased from 68% to 87% (p < 0.05) and, again, the pre-to-post change in scores between training modalities was similar (p > 0.05 for the score difference). Only minimal differences in survey scores between modalities were observed on most measures of participant engagement and experience with the trainings (p > 0.05 for most score differences). CONCLUSIONS: These exploratory results suggest that in-person and virtual contraceptive care trainings yielded comparable results among both clinicians and support staff. IMPLICATIONS: Results from this post-hoc analysis of survey data suggest a general equivalency of effectiveness between in-person trainings and virtual trainings, although in-person trainings may be more satisfying or engaging for participants. Further work and research is needed to inform strategies for making virtual trainings more engaging and satisfying for participants.

RESUMO

BACKGROUND: Although lengthening of the lateral column through an osteotomy of the anterior calcaneus is an integral component of flatfoot reconstruction in younger patients with flexible planovalgus deformities, the procedure has been implicated in iatrogenic calcaneocuboid (CC) subluxation and subsequent degenerative changes at the CC articulation. The purpose of this study is to characterize alterations at the CC joint after lateral column lengthening (LCL) and determine if Steinmann pin stabilization of the CC joint before distraction maintains a normal relationship. METHODS: Seven matched pairs of fresh-frozen cadaveric feet underwent preprocedure plain radiography and cross-sectional computed tomography (CT) imaging. LCL by osteotomy through the anterior calcaneus was then performed. One foot of each matched pair had a single smooth Steinmann pin placed centrally across the CC joint before osteotomy distraction. Distraction across each osteotomy was then performed and maintained with a 12-mm porous titanium wedge. Repeat imaging was obtained and compared with preprocedure studies to quantify sagittal and rotational differences at the CC articulation. RESULTS: Following LCL, plain radiography demonstrated statistically significant increases in the percentage of the calcaneal articular surface dorsal to the superior aspect of the cuboid in both the pinned (8.2% vs. 17.6%, P=0.02) and unpinned (12.5% vs. 16.3%, P=0.04) specimens. No difference in the percentage of subluxation was found between the 2 groups after LCL. CT imaging demonstrated statistically significant increases in rotation between the calcaneus and cuboid after LCL in both the pinned (7.6±5.6 degrees, P=0.01) and unpinned (17±12.3 degrees, P=0.01) specimens. The degree of rotation was greater in unpinned specimens after LCL (P=0.043). CONCLUSIONS: Both sagittal and rotatory subluxation seem to occur at the CC joint after LCL regardless of pin stabilization. As a single pin would be expected to limit pure translation while having little effect on rotation, it is possible that the rotational changes identified on 3-dimensional imaging are interpreted as dorsal translation when viewed 2 dimensionally using plain radiography. Consideration should therefore be given to CC stabilization with 2 pins during LCL to prevent this rotatory subluxation. LEVEL OF EVIDENCE: Level V-cadaver study.

RESUMO

BACKGROUND: Although lengthening of the lateral column through a calcaneal neck osteotomy is an integral component of flatfoot reconstruction in younger patients with flexible planovalgus deformities, concern exists as to the effect of this intra-articular osteotomy on subtalar motion. The purpose of this study was to quantify the alterations in subtalar motion following lateral column lengthening (LCL). METHODS: The subtalar motion of 14 fresh-frozen cadaveric feet was assessed using a 3-dimensional motion capture system and materials testing system (MTS). Following potting of the tibia and calcaneus, optic markers were placed into the tibia, calcaneus, and talus. The MTS was used to apply a rotational force across the subtalar joint to a torque of 5 Nm. Abduction/adduction, supination/pronation, and plantarflexion/dorsiflexion about the talus were recorded. Specimens then underwent LCL via a calcaneal neck osteotomy, which was maintained with a 12-mm porous titanium wedge. Repeat subtalar motion analysis was performed and compared to pre-LCL motion using a paired t test. RESULTS: No statistically significant differences in subtalar abduction/adduction (10.9 vs 11.8 degrees, P = .48), supination/pronation (3.5 vs 2.7 degrees, P = .31), or plantarflexion/dorsiflexion (1.6 vs 1.0 degrees, P = .10) were identified following LCL. CONCLUSION: No significant changes in subtalar motion were observed following lateral column lengthening in this biomechanical cadaveric study. CLINICAL RELEVANCE: Although these findings do not obviate concerns of clinical subtalar stiffness following lateral column lengthening for planovalgus deformity correction, they suggest that diminished postoperative subtalar motion, when it occurs, may be due to soft tissue scarring rather than alterations of joint anatomy.

RESUMO

CASE DESCRIPTION: A 3-year-old neutered male domestic shorthair cat with a history of urethral obstruction was evaluated at a veterinary referral center for acute onset of hunched posture and signs of discomfort on being handled. No evidence of urethral obstruction was found; signs initially responded to medical management, but the cat was presented to the primary care veterinarian < 48 hours after the initial examination with signs suggesting urethral obstruction. CLINICAL FINDINGS: No urinary calculi were detected radiographically. Attempted urinary catheter placement was unsuccessful, and the cat was returned to the referral center for evaluation and treatment of suspected urethral obstruction. Hematologic evaluation revealed hyperglobulinemia and leukocytosis; the cat was febrile, its prepuce was swollen, and its urinary bladder was soft but could not be manually expressed. TREATMENT AND OUTCOME: A urinary catheter was placed; urinalysis revealed hematuria, leukocyturia, and bacteriuria. Medical management included analgesic, antimicrobial, urethral antispasmodic, and IV fluid treatment. Positive-contrast cystourethrography results were equivocal for a congenital anomaly versus urethral rupture. Contrast-enhanced CT revealed a sinus communicating with the dorsal aspect of the urethra, and urethral rupture was ruled out. Partial urethral duplication was confirmed surgically; perineal urethrostomy was performed, creating an opening to the accessory urethra, and the strictured orthotopic urethra was ligated. Four weeks after surgery, the cat was doing well. CLINICAL RELEVANCE: This case highlighted the importance of advanced imaging to distinguish between urethral rupture and a congenital malformation in a cat with signs of lower urinary tract disease. This approach was pivotal to appropriate diagnosis and management and a favorable outcome for the patient.

RESUMO

BACKGROUND: The flexor hallucis longus (FHL) and flexor digitorum longus (FDL) tendons are commonly used for tendon transfer in reconstructive foot and ankle procedures. Some patients experience great toe weakness and loss of push-off strength. The objective of this biomechanical study was to quantify plantarflexion force after FHL and FDL harvest and correlate it to variations in tendon crossover patterns at the knot of Henry to determine if specific patterns have an increased tendency toward forefoot weakness. METHODS: Simulated loads through the Achilles, FHL, and FDL were applied to cadaveric specimens while plantarflexion force was measured using a pressure mapping system. Force was recorded with the FDL and FHL unloaded to simulate tendon transfer. Afterward, specimens were dissected to classify the tendinous slips between the FHL and FDL based on a previously determined system. Functional and anatomical relationships between the classification type and loading patterns were analyzed. RESULTS: There were no statistical differences between the tendon crossover patterns in forefoot force reduction after FHL or FDL harvest. Average decrease in great toe and total forefoot pressure after FHL harvest was 31% and 22%, respectively. Average decrease in lesser toe and total forefoot push-off force after FDL harvest was 23% and 9%, respectively. CONCLUSION: This study quantified loss of plantarflexion force after simulated FHL and FDL harvest and correlated these losses to variations in anatomic crossover patterns at the knot of Henry. Variations at the knot of Henry do not contribute to differences in forefoot weakness. CLINICAL RELEVANCE: The decrease in forefoot pressure seen here would help explain the clinical scenario where a patient does note a loss of great toe strength after FHL transfer.

RESUMO

Sexual minority persons have an increased risk for negative mental health outcomes in adulthood. This seems to largely be due to experiences of stigma in social settings. This study sought to understand the relationship between attending a religiously conservative college, internalized homophobia (a measure of sexual stigma), and depressive symptoms for sexual minority adults. Sexual minority adult participants (n = 384) from across the U.S. were recruited and completed a Web-based, anonymous survey. A mediation model predicting depression through college religious conservatism, college acceptance of sexual minority identities, and internalized homophobia was tested using path analysis. Results revealed an indirect effect of increased religious conservatism of a college predicted higher depression through lower college acceptance and higher internalized homophobia. Implications for the mental health of sexual minority adults and future research are examined.

RESUMO

It is hypothesized that a novel crystalline solid dispersion (CSD) of docetaxel (C-DXT) can be engineered by dispersing native docetaxel (DXT, a BCS class II drug) in sodium acetate crystal (SA). DXT is dissolved in glacial acetic/SA solution and freeze-dried. The resulting C-DXT is characterized by differential scanning calorimetry (DSC), powder X-ray analysis (PXRD), LC-MS/MS, scanning electron microscopy (SEM), transmission electron microscopy (TEM), Quartz crystal microbalance with dissipation monitoring (QCM-D) and dynamic light scattering (DLS). Its cytotoxicity on model cancerous (MCF-7, MDA-MB-468) and normal breast cells (MCF-10A) is assessed by MTS assay. SEM/TEM data and the absence of the characteristics peaks of DXT on the DSC curve (at 193.4 °C) and the XRD scan (at 2θ = 15.31 °C and 23.04 °C) confirm the presence of C-DXT in SA. The LC-MS/MS data indicates the chemical stability of DXT. The yield and C-DXT loading are 95.2% and 6.52% w/w, respectively. The C-DXT rapidly forms an aqueous non-rigid nanosuspension with a faster drug dissolution rate compared to native DXT. Unlike, control Tween 80/ethanol, SA is noncytotoxic to normal cells. However, C-DXT's cytotoxicity is time and dose dependent for all diseased cells. This unique CSD process might be applicable to other hydrophobic bioactive agents to enhance their safety and efficacy.

RESUMO

BACKGROUND: Hallux rigidus is a common osteoarthritic disease of the first metatarsophalangeal joint (MTPJ). Few salvage treatment options exist that preserve motion for patients who have failed an initial procedure and who are not amenable to fusion, typically patients who are active or who would like to wear high heels. Allograft tendon interpositional arthroplasty is an unconventional salvage treatment option that may preserve motion and prevent bone loss. METHODS: A retrospective chart review is reported of 19 patients who failed previous procedures and refused fusion who underwent allograft tendon interpositional arthroplasty of the hallux MTPJ by a single surgeon between 2012 and 2015. Outcomes included the American Orthopaedic Foot & Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal scale assessment as well as measurement of apparent joint space on anterior to posterior and lateral views. RESULTS: The cumulative average AOFAS score for all patients was 68.5 preoperatively and 74.1 postoperatively. The average AOFAS pain subscore was 24.7 preoperatively and 26.8 postoperatively (SD = 7.7 and 13.8, respectively). Radiographically, patients had an increase in apparent joint space from pre- to postoperatively, most notable on the lateral view (0.6 to 4.7 mm; SD = 0.7 and 3.2 mm). Five patients required a second operative procedure, for an overall 26% reoperation rate. One patient underwent hallux MTPJ fusion after the interpositional arthroplasty. An additional 4 patients (21%) had symptoms requiring a steroid injection, and another 3 patients (16%) were recommended to undergo a revision procedure based on their symptoms. CONCLUSION: Rolled allograft tendon interposition arthroplasty performed poorly as a salvage strategy for failed previous hallux MTPJ surgery for hallux rigidus because of a high rate of complication and minimal benefits. The senior author has abandoned the technique. LEVEL OF EVIDENCE: Level IV, retrospective case series.

RESUMO

We examined the use of the Personality Assessment Inventory (PAI) in a small sample of 47 U.S. military veterans of the conflicts in Iraq and Afghanistan. Approximately half of the sample met criteria for posttraumatic stress disorder (PTSD) based on the Clinician-Administered PTSD Scale. PAI profiles were compared between the PTSD and non-PTSD groups. The PTSD group had clinically significant scores (≥ 70 T) on the PAI for 5 clinical scales (anxiety, anxiety-related disorders, depression, paranoia, and schizophrenia) and 10 clinical subscales consistent with the typical symptom picture for PTSD. Effect size correlations ( r) between scales and diagnosis group membership were large ( r ≥ .5) for several scales that reflect PTSD symptoms and for the PTSD LOGIT function. In a receiver operating characteristics curve analysis, the PTSD LOGIT function and the Traumatic Stress Subscale both demonstrated good diagnostic utility (areas under the curve > .80).

RESUMO

Daily distribution of dietary protein may be important in protecting against sarcopenia, specifically in terms of per meal amounts relative to a proposed threshold for maximal response. The aims of this study were to determine total and per meal protein intake in older adults, as well as identifying associations with physical activity and sedentary behavior. Three-day food diaries recorded protein intake in 38 participants. Protein distribution, coefficient of variation (CV), and per meal amounts were calculated. Accelerometry was used to collect physical activity data as well as volume and patterns of sedentary time. Average intake was 1.14 g·kg-1·day-1. Distribution was uneven (CV = 0.67), and 79% of participants reported <0.4 g·kg-1 protein content in at least 2/3 daily meals. Protein intake was significantly correlated with step count (r = 0.439, p = 0.007) and negatively correlated with sedentary time (r = -0.456, p = 0.005) and Gini index G, which describes the pattern of accumulation of sedentary time (r = -0.421, p = 0.011). Total daily protein intake was sufficient; however, distribution did not align with the current literature; increasing protein intake may help to facilitate optimization of distribution. Associations between protein and other risk factors for sarcopenia may also inform protective strategies.

RESUMO

OBJECTIVE: To describe the successful treatment of loperamide toxicosis in a dog using intravenous lipid emulsion (ILE). CASE SUMMARY: An 8-month-old male neutered Rough Collie weighing 20.0 kg was given a total dose of 0.75 mg/kg loperamide over 3 days as treatment for diarrhea. The dog was subsequently evaluated for signs of dull mentation, anxiety, ptyalism and ataxia, thought to be a result of loperamide intoxication. The dog was treated with a 1.5 mL/kg IV bolus of 20% ILE solution followed by 0.25 mL/kg/min of the same solution for 2 hours. The dog's mentation improved rapidly following ILE infusion, and he was neurologically normal 3 hours after initiation of ILE treatment. The dog was subsequently found to be homozygous for the ATP-binding cassette (ABC) transporter gene (ABCB1-1∆) mutation. There were no adverse effects noted during or following ILE infusion. NEW OR UNIQUE INFORMATION PROVIDED: ILE was successful in the treatment of loperamide toxicosis in a Collie with the ABCB1-1∆ mutation. ILE may be of benefit for treatment of other intoxications in dogs with ABCB1-1Δ mutations.

RESUMO

BACKGROUND AND AIMS: Physical activity and nutritional supplementation interventions may be used to ameliorate age-related loss of skeletal muscle mass and function. Previous reviews have demonstrated the beneficial effects of resistance exercise training (RET) combined with protein or essential amino acids (EAA) in younger populations. Whether or not older adults also benefit is unclear. The aim of this review was to determine whether regular dietary supplementation with protein/EAA during a RET regimen augments the effects of RET on skeletal muscle in older adults. METHODS: A literature search was conducted in August 2015 using MEDLINE, EMBASE, SPORTDiscus, and CINAHL Plus to identify all controlled trials using a RET regimen with and without protein/EAA supplementation. Outcome variables included muscle strength, muscle size, functional ability, and body composition. RESULTS: Fifteen studies fulfilled the eligibility criteria, including 917 participants with a mean age of 77.4 years. Studies involving both healthy participants and those described as frail or sarcopenic were included. Overall, results indicated that protein supplementation did not significantly augment the effects of RET on any of the specified outcomes. Exceptions included some measures of muscle strength (3 studies) and body composition (2 studies). Meta-analyses were conducted but were limited because of methodologic differences between studies, and results were inconclusive. CONCLUSIONS: Systematic review and meta-analysis of controlled trials reveal that protein/EAA supplementation does not significantly augment the effects of progressive RET in older adults.

RESUMO

OBJECTIVE: To evaluate a clinical population of dogs exposed to selective serotonin reuptake inhibitor (SSRI) antidepressant medications and describe the clinical findings, epidemiological characteristics, outcome, and prognosis. DESIGN: Retrospective study (February 1, 2005-August 31, 2010). SETTING: Animal poison control helpline. ANIMALS: Three hundred thirteen dogs with presumed SSRI toxicosis. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Dogs with presumptive SSRI medication toxicosis identified by a review of the electronic database of Pet Poison Helpline, an animal poison control center, were evaluated. No clinical signs were reported in 76.3% (239/313) of cases. The remaining 23.6% (74/313) of cases demonstrated the following clinical signs: neurological 79.7% (59/74), gastrointestinal 25.6% (19/74), cardiovascular 9.5% (7/74), respiratory 8.2% (6/74), and thermoregulatory 6.7% (5/74). Of the dogs exhibiting neurological signs, 62.7% (37/59) showed depression, 37.2% (22/59) showed hyperactivity, 10.1% (6/59) exhibited ataxia, and 1.7% (1/59) showed other miscellaneous signs (eg, hyperesthesia). There was a significant difference between the dose ingested by symptomatic and asymptomatic dogs for fluoxetine (P = 0.0039), but not with any other SSRI. Ninety-four patients were confirmed to have received veterinary care. In cases where duration of veterinary care was determined (55/313), 67.2% (37/55) of dogs were hospitalized and 32.7% (18/55) treated as outpatients. The average duration of hospitalization was 18.5 hours, excluding outpatient visits. Of those patients that had complete follow-up information available (136/313), overall survival was 100%. CONCLUSIONS: The overall prognosis for animals with SSRI toxicosis is excellent with veterinary attention. Central nervous system depression was the most common clinical sign associated with SSRI toxicosis.

RESUMO

BACKGROUND: The inactivity physiology paradigm proposes that sedentary behaviors, including sitting too much, are independent of the type of physical activity delineated for health in the Physical Activity Guidelines for Americans. Thus, we hypothesized that, when accounting for behaviors across the entire day, variability in the amount of time spent sitting would be independent of the inter-and intra-individual time engaged in sustained moderate-to-vigorous physical activity (MVPA). METHODS: Ninety-one healthy women, aged 40-75 years, completed a demographic questionnaire and assessment of height and weight. Participants wore the activPAL activity monitor for one week and time (minutes/day) spent sitting, standing, stepping, and in sustained bouts (bouts ≥10 minutes) of MVPA were quantified. The women were then stratified into groups based on weekly sustained MVPA. Additionally, each day of data collection for each participant was classified as either a "sufficient" MVPA day (≥ 30 min of MVPA) or an "insufficient" MVPA day for within-participant analyses. RESULTS: Time spent sitting, standing, and in incidental non-exercise stepping averaged 64, 28, and 11 hrs/week, respectively, and did not differ between groups with individuals meeting/exceeding the current exercise recommendation of 150 min/week of sustained MVPA in ≥10 minutes bouts (M = 294 min/week, SD = 22) compared to those with none or minimal levels (M= 20 min/week, SD = 4). Time spent sitting (M = 9.1 hr/day, SD = 0.19 vs. M = 8.8 hr/day, SD = 0.22), standing (M = 3.9 hr/day, SD = 0.16 vs. M = 3.9 hr/day, SD = 0.15), and in intermittent stepping (M = 1.6 hr/day, SD = 0.07 vs. M = 1.6 hr/day, SD = 0.06) did not differ between days with (~55 min/day) and without recommended MVPA. CONCLUSIONS: This study provides the first objective evidence that participation in sustained MVPA is unrelated to daily sitting duration in relatively healthy, middle and older-aged women. More research is needed to extend these findings to other populations and to inform distinct behavioral recommendations focused on sedentary time.

RESUMO

Oral manifestations of nutritional deficiencies can affect the mucous membranes, teeth, periodontal tissue, salivary glands, and perioral skin. This contribution reviews how the water-soluble vitamins (B(2), B(3), B(6), B(12), C, and folic acid), fat-soluble vitamins (A, D, and E), and minerals (calcium, fluoride, iron, and zinc) can affect the oral mucosa.

RESUMO

Following exposure to experimenter-provided examples of space creatures, people tend to conform to the features contained in the examples when creating their own novel space creatures. In three experiments, we manipulated factors known to affect source-monitoring accuracy to determine how these manipulations would influence conformity to experimenter-provided examples. In Experiment 1 we altered people's cognitive agenda by means of the instructions given before the drawing task. In Experiment 2 we examined how time pressure would affect the level of conformity, and in Experiment 3 we manipulated the availability of the creatures during the drawing task by making them available to half the participants. Conformity decreased when extended source-monitoring processes were engaged and increased when these processes were disrupted. The results from the three experiments were consistent with the principles of the source-monitoring framework.
