Evidence of educational inadequacies in region-specific musculoskeletal medicine.
Day, Charles S; Yeh, Albert C
2008-10-01
Recent studies suggest US medical schools are not effectively addressing musculoskeletal medicine in their curricula. We examined if there were specific areas of weakness by analyzing students' knowledge of and confidence in examining specific anatomic regions. A cross-sectional survey study of third- and fourth-year students at Harvard Medical School was conducted during the 2005 to 2006 academic year. One hundred sixty-two third-year students (88% response) and 87 fourth-year students (57% response) completed the Freedman and Bernstein cognitive mastery examination in musculoskeletal medicine and a survey eliciting their clinical confidence in examining the shoulder, elbow, hand, back, hip, knee, and foot on a one to five Likert scale. We specifically analyzed examination questions dealing with the upper extremity, lower extremity, back, and others, which included more systemic conditions such as arthritis, metabolic bone diseases, and cancer. Students failed to meet the established passing benchmark of 70% in all subgroups except for the others category. Confidence scores in performing a physical examination and in generating a differential diagnosis indicated students felt below adequate confidence (3.0 of 5) in five of the seven anatomic regions. Our study provides evidence that region-specific musculoskeletal medicine is a potential learning gap that may need to be addressed in the undergraduate musculoskeletal curriculum.

Polyneuropathy is one of the most prevalent neurologic disorders. Although several studies explored the role of the neurological examination in polyneuropathy, they were mostly restricted to specific subgroups of patients and have not correlated examination findings with symptoms and electrophysiological results. To explore the sensitivity and specificity of different neurological examination components in patients with diverse etiologies for polyneuropathy, find the most sensitive combination of examination components for polyneuropathy detection, and correlate examination findings with symptoms and electrophysiological results. Patients with polyneuropathy attending the neuromuscular clinic from 01/2013 to 09/2015 were evaluated. Inclusion criteria included symptomatic polyneuropathy, which was confirmed by electrophysiological studies. 47 subjects with no symptoms or electrophysiological findings suggestive for polyneuropathy, served as controls. The total cohort included 312 polyneuropathy patients, with a mean age of 60±14 years. Abnormal examination was found in 95%, most commonly sensory findings (86%). The most common abnormal examination components were impaired ankle reflexes (74%), vibration (73%), and pinprick (72%) sensation. Combining ankle reflex examination with vibration or pinprick perception had the highest sensitivity, of 88%. The specificities of individual examination component were generally high, excluding ankle reflexes (62%), and vibration perception (77%). Abnormal examination findings were correlated with symptomatic weakness and worse electrophysiological parameters. The neurological examination is a valid, sensitive and specific tool for diagnosing polyneuropathy, and findings correlate with polyneuropathy severity. Ankle reflex examination combined with either vibration or pinprick sensory testing is the most sensitive combination for diagnosing polyneuropathy, and should be considered minimal essential components of the physical examination in patients with suspected polyneuropathy.

Recent changes in the periodicity of cervical cancer screening have led to questions about the role of screening pelvic examinations among asymptomatic women. To systematically review literature on health benefits, accuracy, and harms of the screening pelvic examination for gynecologic conditions for the US Preventive Services Task Force (USPSTF). MEDLINE, PubMed, and Cochrane Central Register of Controlled Trials for relevant English-language studies published through January 13, 2016, with surveillance through August 3, 2016. Two reviewers independently screened abstracts and studies. The search yielded 8678 unique citations; 316 full-text articles were reviewed, and 9 studies including 27 630 patients met inclusion criteria. Two reviewers rated study quality using USPSTF criteria. Morbidity; mortality; diagnostic accuracy for any gynecologic cancer or condition except cervical cancer, gonorrhea, and chlamydia, which are covered by other USPSTF screening recommendations; harms (false-positive rates, false-negative rates, surgery rates). No trials examined the effectiveness of the pelvic examination in reducing all-cause mortality, reducing cancer- and disease-specific morbidity and mortality, or improving quality of life. Eight studies reported accuracy for the screening pelvic examination: ovarian cancer (4 studies; n = 26 432), bacterial vaginosis (2 studies; n = 930), trichomoniasis (1 study; n = 779), and genital herpes (1 study; n = 779). In the 4 ovarian cancer screening studies, low prevalence of ovarian cancer consistently resulted in low positive predictive values (PPVs) and false-positive rates, with a lack of precision in accuracy estimates (sensitivity range, 0%-100%; specificity range, 91%-99%; PPV range, 0%-3.6%; negative predictive value [NPV] range, ≥99%). Each diagnostic accuracy study for bacterial vaginosis, trichomoniasis, and genital herpes was performed in a high-prevalence population with substantial proportions of symptomatic patients and reported accuracy characteristics for individual physical examination findings (bacterial vaginosis, homogeneous discharge: sensitivity range, 69%-79%; specificity range, 54%-97%; PPV range, 52%-95%; NPV range, 79%-80%; herpes simplex virus, vulvar ulcerations: sensitivity, 20%; specificity, 98%; PPV, 88%; NPV, 57%; trichomoniasis, colpitis macularis: sensitivity, 2%; specificity, 100%; PPV, 100%; NPV, 85%). Surgery rates resulting from an abnormal screening pelvic examination for ovarian cancer ranged from 5% to 36% at 1 year, with the largest study reporting an 11% surgery rate and 1% complication rate within 1 year of a screening pelvic examination with abnormal findings. No direct evidence was identified for overall benefits and harms of the pelvic examination as a 1-time or periodic screening test. Limited evidence was identified regarding the diagnostic accuracy and harms of routine screening pelvic examinations in asymptomatic primary care populations.

To examine the validity of self-reported eye disease, including cataract, age-related macular degeneration (AMD), glaucoma, and diabetic retinopathy (DR), and self-reported surgical treatment for cataract and DR in the Los Angeles Latino Eye Study (LALES). Population-based, cross-sectional study. A total of 6357 Latinos aged 40+ years from the LALES. Participants underwent a detailed interview, including survey questions about ocular health, diagnoses, and timing of last eye examination, and a standardized clinical examination. Self-report was compared with examination to determine sensitivity and specificity by length of time since last eye examination. Stepwise logistic regression was used to determine factors associated with inaccurate self-report. Sensitivity and specificity were calculated for 4 self-reported eye diseases (cataract, AMD, glaucoma, and DR) and for surgical treatment of cataract and DR. Odds ratios (ORs) were determined for factors associated with inaccurate self-report underestimating eye disease and treatment. For each disease, sensitivity and specificity in those who reported their last eye examination as <1 year ago were 36.8% and 92.5% for cataract, 37.7% and 96.3% for glaucoma, 5.1% and 98.9% for AMD, and 25.7% and 94.2% for DR, respectively. Self-report was less accurate with increasing time since last eye examination. Inaccurate self-report was independently associated with better visual acuity (OR, 2.4), <2 comorbidities (OR, 1.7), last eye examination/visit 1 to 5 years ago and ≥ 5 years ago (OR, 2.3 and 4.9, respectively), and less education (OR, 1.3 for 7-12 years and 1.7 for <7 years). Of 88 participants surgically treated for cataract who reported an eye examination <1 year ago, sensitivity and specificity of self-reported surgical history were 90.9% and 99.9%, respectively. Of the 31 participants treated for DR (laser/surgery) and reporting an eye examination <1 year ago, sensitivity and specificity of self-reported surgical history were 19.4% and 99.6%, respectively. Among Latinos, self-reporting of eye disease and surgical history provides a significant underestimate of the disease burden. This may lead to significant misclassification in vision research if self-report alone is used to identify persons with eye disease. Copyright © 2012 American Academy of Ophthalmology.

Vitamin C and survival among women with breast cancer: a meta-analysis.
Harris, Holly R; Orsini, Nicola; Wolk, Alicja
2014-05-01
The association between dietary vitamin C intake and breast cancer survival is inconsistent and few studies have specifically examined vitamin C supplement use among women with breast cancer. The purpose of this study was to summarise results from prospective studies on the association between vitamin C supplement use and dietary vitamin C intake and breast cancer-specific mortality and total mortality. Studies were identified using the PubMed database through February 6, 2014 and by examining the references of retrieved articles. Prospective studies were included if they reported relative risks (RR) with 95% confidence intervals (95% CIs) for at least two categories or as a continuous exposure. Random-effects models were used to combine study-specific results. The ten identified studies examined vitamin C supplement use (n=6) and dietary vitamin C intake (n=7) and included 17,696 breast cancer cases, 2791 total deaths, and 1558 breast cancer-specific deaths. The summary RR (95% CI) for post-diagnosis vitamin C supplement use was 0.81 (95% CI 0.72-0.91) for total mortality and 0.85 (95% CI 0.74-0.99) for breast cancer-specific mortality. The summary RR for a 100mg per day increase in dietary vitamin C intake was 0.73 (95% CI 0.59-0.89) for total mortality and 0.78 (95% CI 0.64-0.94) for breast cancer-specific mortality. Results from this meta-analysis suggest that post-diagnosis vitamin C supplement use may be associated with a reduced risk of mortality. Dietary vitamin C intake was also statistically significantly associated with a reduced risk of total mortality and breast cancer-specific mortality. Copyright © 2014 Elsevier Ltd.

Near Infrared Imaging as a Diagnostic Tool for Detecting Enamel Demineralization: An in vivo Study
NASA Astrophysics Data System (ADS)
Lucas, Seth Adam
Background and Objectives: For decades there has been an effort to develop alternative optical methods of imaging dental decay utilizing non-ionizing radiation methods. The purpose of this in-vivo study was to demonstrate whether NIR can be used as a diagnostic tool to evaluate dental caries and to compare the sensitivity and specificity of this method with that of conventional methods, including bitewing x-rays and visual inspection. Materials and Methods: 31 test subjects (n=31) from the UCSF orthodontic clinic undergoing orthodontic treatment with planned premolar extractions were recruited. Calibrated examiners performed caries detection examinations using conventional methods: bitewing radiographs and visual inspection. These findings were compared with the results from NIR examinations: transillumination and reflectance. To confirm the results found in the two different detection methods, a gold standard was used. After teeth were extracted, polarized light microscopy and transverse microradiography were performed. Results: A total of 87 premolars were used in the study. NIR identified the occlusal lesions with a sensitivity of 71% and a specificity of 77%, whereas, the visual examination had a sensitivity of only 40% and a specifity of 39%. For interproximal lesions halfway to DEJ, specificity remained constant, but sensitivity improved to 100% for NIR and 75% for x-rays. Conclusions: The results of this preliminary study demonstrate that NIR is just as effective at detecting enamel interproximal lesions as standard dental x-rays. NIR was more effective at detecting occlusal lesions than visual examination alone. NIR shows promise as an alternative diagnostic tool to the conventional methods of x-rays and visual examination and provides a non-ionizing radiation technique.

This systematic review examined the effectiveness of specific sensory techniques and sensory environmental modifications to improve participation of children with sensory integration (SI) difficulties. Abstracts of 11,436 articles published between January 2007 and May 2015 were examined. Studies were included if designs reflected high levels of evidence, participants demonstrated SI difficulties, and outcome measures addressed function or participation. Eight studies met inclusion criteria. Seven studies evaluated effects of specific sensory techniques for children with autism spectrum disorder (ASD) or attention deficit hyperactivity disorder: Qigong massage, weighted vests, slow swinging, and incorporation of multisensory activities into preschool routines. One study of sensory environmental modifications examined adaptations to a dental clinic for children with ASD. Strong evidence supported Qigong massage, moderate evidence supported sensory modifications to the dental care environment, and limited evidence supported weighted vests. The evidence is insufficient to draw conclusions regarding slow linear swinging and incorporation of multisensory activities into preschool settings.

Among the non-motor features of Parkinson's disease (PD), cognitive impairment is one of the most troublesome problems. Highly sensitive and specific screening instruments for detecting dementia in PD (PDD) are required in the clinical practice. In our study we evaluated the sensitivity and specificity of different neuropsychological tests (Addenbrooke's Cognitive Examination, ACE; Frontal Assessment Battery, FAB and Mattis Dementia Rating Scale, MDRS) in 73 Parkinson's disease patients without depression. By receiver operating characteristic curve analysis, these screening instruments were tested against the recently established clinical diagnostic criteria of PDD. Best cut-off score for ACE to identify PDD was 80 points (sensitivity = 74.0%, specificity = 78.1%). For FAB the most optimal cut-off value was 12 points (sensitivity = 66.3%, specificity = 72.2%); whereas for MDRS it was 125 points (sensitivity = 89.8%, specificity = 98.3%). Among the examined test batteries, MDRS had the best clinicometric profile for detecting PDD. Although the types of applied screening instruments might differ from movement disorder clinic to clinic within a country, determination of the most specific and sensitive test for the given population remains to be an important task. Our results demonstrated that the specificity and sensitivity of MDRS was better than those of ACE, FAB and MMSE in Hungary. However, further studies with larger sample size and more uniform criteria for participation are required to determine the most suitable screening instrument for cognitive impairment.

Shoulder pain in the general population is common and to identify the aetiology of shoulder pain, history, motion and muscle testing, and physical examination tests are usually performed. The aim of this systematic review was to summarise and evaluate intrarater and inter-rater reliability of physical examination tests in the diagnosis of shoulder pathologies. A comprehensive systematic literature search was conducted using MEDLINE, EMBASE, Allied and Complementary Medicine Database (AMED) and Physiotherapy Evidence Database (PEDro) through 20 March 2015. Methodological quality was assessed using the Quality Appraisal of Reliability Studies (QAREL) tool by 2 independent reviewers. The search strategy revealed 3259 articles, of which 18 finally met the inclusion criteria. These studies evaluated the reliability of 62 test and test variations used for the specific physical examination tests for the diagnosis of shoulder pathologies. Methodological quality ranged from 2 to 7 positive criteria of the 11 items of the QAREL tool. This review identified a lack of high-quality studies evaluating inter-rater as well as intrarater reliability of specific physical examination tests for the diagnosis of shoulder pathologies. In addition, reliability measures differed between included studies hindering proper cross-study comparisons. PROSPERO CRD42014009018. Published by the BMJ Publishing Group Limited.

The goal of the present study was to examine the links between life events and adolescents' social behaviors (prosocial and aggressive behaviors) toward specific targets and to examine how empathic concern may play a role in these associations. The study examined two hypotheses: both the mediating role of empathic concern and the moderating role of empathic concern. The sample included 311 high school students from the Midwest (M age = 16.10 years; age range = 14-19 years; 58.7% girls; 82.7% White, 13.6% Latino). The results demonstrated support for the moderation model as well as complex links between life events and prosocial and aggressive behaviors toward specific targets. The discussion focuses on the role of empathic concern in understanding how life events are ultimately associated with adolescents' social development.

Reference/Citation: Calvert E, Chambers GK, Regan W, Hawkins RH, Leith JM. Special physical examination tests for superior labrum anterior-posterior shoulder injuries are clinically limited and invalid: a diagnostic systematic review. J Clin Epidemiol. 2009;62(5):558–563. Clinical Question: The systematic review focused on diagnostic accuracy studies to determine if evidence was sufficient to support the use of superior labrum anterior-posterior (SLAP) physical examination tests as valid and reliable. The primary question was whether there was sufficient evidence in the published literature to support the use of SLAP physical examination tests as valid and reliable diagnostic test procedures. Data Sources: Studies published in English were identified through database searches on MEDLINE, EMBASE, and the Cochrane database (1970–2004) using the search term SLAP lesions. The medical subject headings of arthroscopy, shoulder joint, and athletic injuries were combined with test or testing, physical examination, and sensitivity and specificity to locate additional sources. Other sources were identified by rereviewing the reference lists of included studies and review articles. Study Selection: Studies were eligible based on the following criteria: (1) published in English, (2) focused on the physical examination of SLAP lesions, and (3) presented original data. A study was excluded if the article was limited to a clinical description of 1 or more special tests without any research focus to provide clinical accuracy data or if it did not focus on the topic. Data Extraction: The abstracts that were located through the search strategies were reviewed, and potentially relevant abstracts were selected. Strict epidemiologic methods were used to obtain and collate all relevant studies; the authors developed a study questionnaire to record study name, year of publication, study design, sample size, and statistics. Validity of the diagnostic test study was determined by applying the 5 criteria proposed by Calvert et al. If the study met the inclusion and validity criteria, 95% confidence intervals were calculated for each sensitivity, specificity, and positive and negative likelihood ratio reported. No specific information was provided about the procedure if the reviewers disagreed on how the evaluation criteria were applied. Main Results: The specific search criteria led to the identification of 29 full-text articles. The studies were reviewed, and inclusion and exclusion criteria were applied. This resulted in 14 excluded studies and 15 eligible studies for analysis. Of the 15 eligible studies, 1 evaluated only a single physical examination test for a SLAP lesion or biceps tendon injury, and 10 studies evaluated 2 to 6 physical examination tests for a SLAP lesion or biceps tendon injury. Nine studies reported sensitivities and specificities greater than 75%, 4 had sensitivities less than 75%, 3 had specificities less than 75%, 1 did not report sensitivity, and 2 did not report specificities. When validity was assessed for those 15 papers, only 1 study that evaluated the biceps tendon met the 5 critical appraisal criteria of Calvert et al and calculated 95% confidence intervals. When the Speed and Yergason tests were each compared with the gold standard (arthroscopy), the confidence intervals for the positive and negative likelihood ratios spanned 1. This indicated that the test result is unlikely to change the odds of having or not having the condition, respectively. Conclusions: The literature currently used as a reference for teaching in medical schools and continuing education lacks the necessary validity to help rule in or out a SLAP lesion or biceps tendon involvement. Based on the results from the systematic review conducted by Calvert et al, no tests clinically diagnose a SLAP lesion. This is a cause for concern as magnetic resonance imaging or magnetic resonance arthrography, which are frequently used to assess a possible SLAP lesion, may also have diagnostic flaws and may be cost prohibitive. Performing arthroscopy on every patient to rule the condition in or out is unethical, especially if a SLAP lesion is not present. More rigorous validity studies should be conducted for SLAP lesion physical examination tests using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tool or Standards for Reporting Diagnostic Accuracy (STARD) criteria.

Evaluation of acute knee pain in primary care.
Jackson, Jeffrey L; O'Malley, Patrick G; Kroenke, Kurt

The evaluation of acute knee pain often includes radiography of the knee. To synthesize the literature to determine the role of radiologic procedures in evaluating common causes of acute knee pain: fractures, meniscal or ligamentous injuries, osteoarthritis, and pseudogout. MEDLINE search from 1966 to October 2002. We included all published, peer-reviewed studies of decision rules for fractures. We included studies that used arthroscopy as the gold standard for measuring the accuracy of the physical examination and magnetic resonance imaging (MRI) for meniscal and ligamentous knee damage. We included all studies on the use of radiographs in pseudogout. We extracted all data in duplicate and abstracted physical examination and MRI results into 2 x 2 tables. Among the 5 decision rules for deciding when to use plain films in knee fractures, the Ottawa knee rules (injury due to trauma and age >55 years, tenderness at the head of the fibula or the patella, inability to bear weight for 4 steps, or inability to flex the knee to 90 degrees) have the strongest supporting evidence. When the history suggests a potential meniscal or ligamentous injury, the physical examination is moderately sensitive (meniscus, 87%; anterior cruciate ligament, 74%; and posterior cruciate ligament, 81%) and specific (meniscus, 92%; anterior cruciate ligament, 95%; and posterior cruciate ligament, 95%). The Lachman test is more sensitive and specific for ligamentous tears than is the drawer sign. For meniscal tears, joint line tenderness is sensitive (75%) but not specific (27%), while the McMurray test is specific (97%) but not sensitive (52%). Compared with the physical examination, MRI is more sensitive for ligamentous and meniscal damage but less specific. When the differential diagnosis for acute knee pain includes an exacerbation of osteoarthritis, clinical features (age >50 years, morning stiffness <30 minutes, crepitus, or bony enlargement) are 89% sensitive and 88% specific for underlying chronic arthritis. Adding plain films improves sensitivity slightly but not specificity. Plain films for pseudogout are not sensitive or specific, according to limited-quality studies. We recommend the Ottawa knee rules to decide when to obtain plain films for suspected knee fracture. A careful physical examination should be sufficient to decide whether to refer patients with potential meniscal and ligament injuries, and we prefer clinical criteria rather than plain films for evaluating osteoarthritis. We do not recommend using plain films to diagnose pseudogout.

Miniaturization has evolved in the creation of a pocket-size imaging device which can be utilized as an ultrasound stethoscope. This study assessed the additional diagnostic power of pocket size device by both experts operators and trainees in comparison with physical examination and its appropriateness of use in comparison with standard echo machine in a non-cardiologic population. Three hundred four consecutive non cardiologic outpatients underwent a sequential assessment including physical examination, pocket size imaging device and standard Doppler-echo exam. Pocket size device was used by both expert operators and trainees (who received specific training before the beginning of the study). All the operators were requested to give only visual, qualitative insights on specific issues. All standard Doppler-echo exams were performed by expert operators. One hundred two pocket size device exams were performed by experts and two hundred two by trainees. The time duration of the pocket size device exam was 304 ± 117 sec. Diagnosis of cardiac abnormalities was made in 38.2% of cases by physical examination and in 69.7% of cases by physical examination + pocket size device (additional diagnostic power = 31.5%, p < 0.0001). The overall K between pocket size device and standard Doppler-echo was 0.67 in the pooled population (0.84 by experts and 0.58 by trainees). K was suboptimal for trainees in the eyeball evaluation of ejection fraction, left atrial dilation and right ventricular dilation. Overall sensitivity was 91% and specificity 76%. Sensitivity and specificity were lower in trainees than in experts. In conclusion, pocket size device showed a relevant additional diagnostic value in comparison with physical examination. Sensitivity and specificity were good in experts and suboptimal in trainees. Specificity was particularly influenced by the level of experience. Training programs are needed for pocket size device users. PMID:21110840

The development of a quality appraisal tool for studies of diagnostic reliability (QAREL).
Lucas, Nicholas P; Macaskill, Petra; Irwig, Les; Bogduk, Nikolai
2010-08-01
In systematic reviews of the reliability of diagnostic tests, no quality assessment tool has been used consistently. The aim of this study was to develop a specific quality appraisal tool for studies of diagnostic reliability. Key principles for the quality of studies of diagnostic reliability were identified with reference to epidemiologic principles, existing quality appraisal checklists, and the Standards for Reporting of Diagnostic Accuracy (STARD) and Quality Assessment of Diagnostic Accuracy Studies (QUADAS) resources. Specific items that encompassed each of the principles were developed. Experts in diagnostic research provided feedback on the items that were to form the appraisal tool. This process was iterative and continued until consensus among experts was reached. The Quality Appraisal of Reliability Studies (QAREL) checklist includes 11 items that explore seven principles. Items cover the spectrum of subjects, spectrum of examiners, examiner blinding, order effects of examination, suitability of the time interval among repeated measurements, appropriate test application and interpretation, and appropriate statistical analysis. QAREL has been developed as a specific quality appraisal tool for studies of diagnostic reliability. The reliability of this tool in different contexts needs to be evaluated.

Background . Rome III criteria add physiological criteria to symptom-based criteria of chronic constipation (CC) for the diagnosis of defecatory disorders (DD). However, a gold-standard test is still lacking and physiological examination is expensive and time-consuming. Aim . Evaluate the usefulness of two low-cost tests-digital rectal examination (DRE) and balloon expulsion test (BET)-as screening or excluding tests of DD. Methods . We performed a systematic search in PUBMED and MEDLINE. We selected studies where constipated patients were evaluated by DRE or BET. Heterogeneity was assessed and random effect models were used to calculate the sensitivity, specificity, and negative predictive value (NPV) of the DRE and the BET. Results . Thirteen studies evaluating BET and four studies evaluating DRE (2329 patients) were selected. High heterogeneity ( I 2 > 80%) among studies was demonstrated. The studies evaluating the BET showed a sensitivity and specificity of 67% and 80%, respectively. Regarding the DRE, a sensitivity of 80% and specificity of 84% were calculated. NPV of 72% for the BET and NPV of 64% for the DRE were estimated. The sensitivity and specificity were similar when we restrict the analysis to studies using Rome criteria to define CC. The BET seems to perform better when a cut-off time of 2 minutes is used and when it is compared with a combination of physiological tests. Considering the DRE, strict criteria seem to improve the sensitivity but not the specificity of the test. Conclusion . Neither of the low-cost tests seems suitable for screening or excluding DD.

Many older adults with Major Depressive Disorder (MDD) do not respond to antidepressant monotherapy. While there are evidence-based treatment options to support treatment beyond monotherapy for adults, the evidence for such strategies specifically in late-life MDD is relatively scarce. This review examines the published data describing strategies for antidepressant augmentation or acceleration studied specifically in older adults, including lithium, stimulants, and second-generation antipsychotics. In addition, the authors suggest strategies for future research, such as study of specific agents, refining understanding of the impact of medical or cognitive comorbidity in late-life depression, and comparative effectiveness to examine methods already used in clinical practice.

In the working age group, diabetic retinopathy is a leading cause of visual impairment. Regular eye examinations and early treatment of retinopathy can prevent visual loss, so screening for diabetic retinopathy is cost-effective. Dilated retinal digital photography with the additional use of ophthalmoscopy is the most effective and robust method of diabetic retinopathy screening. The aim of this study was to estimate the sensitivity and specificity of diabetic retinopathy screening when performed by Norwegian optometrists. This study employed a cross-sectional experimental design. Seventy-four optometrists working in private optometric practice were asked to screen 14 single-field retinal images for possible diabetic retinopathy. The screening was undertaken using a web-based visual identification and management of ophthalmological conditions (VIMOC) examination. The images used in the VIMOC examination were selected from a population survey and had been previously examined by two independent ophthalmologists. In order to establish a "gold standard", images were only chosen for use in the VIMOC examination if they had elicited diagnostic agreement between the two independent ophthalmologists. To reduce the possibility of falsely high specificity occurring by chance, half the presented images were of retinas that were not affected by diabetic retinopathy. Sensitivity and specificity for diabetic retinopathy was calculated with 95% confidence intervals (CIs). The mean (95%CI) sensitivity for identifying eyes with any diabetic retinopathy was 67% (62% to 72%). The mean (95%CI) specificity for identifying eyes without diabetic retinopathy was 84% (80% to 89%). The mean (95%CI) sensitivity for identifying eyes with mild non-proliferative diabetic retinopathy or moderate non-proliferative diabetes was 54% (47% to 61%) and 100%, respectively. Only four optometrists (5%) met the required standard of at least 80% sensitivity and 95% specificity that has been previously set for diabetic retinopathy screening programmes. The evaluation of retinal images for diabetic retinopathy by Norwegian optometrists does not meet the required screening standard of at least 80% sensitivity and 95% specificity. The introduction of measures to improve this situation could have implications for both formal optometric training and continuing optometric professional education.

Interest in subtypes of mental disorders is growing in parallel with continuing research progress in psychiatry. The aim of this study was to examine pure animal phobia in contrast to other specific phobias and a mixed subtype. Data from three representative Swiss community samples were analysed: PsyCoLaus (n = 3720), the ZInEP Epidemiology Survey (n = 1500) and the Zurich Study (n = 591). Pure animal phobia and mixed animal/other specific phobias consistently displayed a low age at onset of first symptoms (8-12 years) and clear preponderance of females (OR > 3). Meanwhile, other specific phobias started up to 10 years later and displayed almost a balanced sex ratio. Pure animal phobia showed no associations with any included risk factors and comorbid disorders, in contrast to numerous associations found in the mixed subtype and in other specific phobias. Across the whole range of epidemiological parameters examined in three different samples, pure animal phobia seems to represent a different entity compared to other specific phobias. The etiopathogenetic mechanisms and risk factors associated with pure animal phobias appear less clear than ever.
Cognitions and distress in caregivers after their child's sexual abuse disclosure.
Runyon, Melissa K; Spandorfer, Ellen D; Schroeder, Christine M
2014-01-01
The impact of child sexual abuse on children is well documented, but few studies have examined the impact of a child's sexual abuse disclosure on maternal caregivers. The studies that have been conducted suggest that parental response postdisclosure is variable. The present study examined the association between maternal attributions and abuse-specific cognitions with depression and trauma symptoms postdisclosure. Participants included 68 nonoffending maternal caregivers of children between the ages of 3 and 17 years who experienced child sexual abuse. Findings indicated that caregivers' abuse-specific cognitions were the best predictor of self-reported symptoms of depression after controlling for general negative attributions. These findings suggest that in order to reduce caregivers' distress and to enhance their support of their children, it is important to assess and treat caregivers' abuse-specific cognitions.

To examine the feasibility of implementing a standardized, clinically relevant genitourinary examination for both men and women, and to identify physical examination findings characteristic of urologic chronic pelvic pain syndrome (UCPPS). This study analyzed 2 samples: men and women with UCPPS who participated in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Research Network Epidemiology and Phenotyping (EP) Study, and age-matched controls who were either positive for chronic fatigue syndrome or healthy (pain-free). We compared physical examination findings in both positive and healthy controls with UCPPS cases: findings from both the EP examinations and from an extended genitourinary examination. EP and extended examinations were performed on 143 participants: 62 UCPPS cases (30 women, 32 men), 42 positive controls (15 women, 27 men), and 39 healthy controls (22 women, 17 men). EP examinations showed that pelvic floor tenderness was more prevalent in cases (55.0%) than in positive (14.6%) or healthy controls (10.5%). Extended examinations revealed specific areas of tenderness in the pelvic floor musculature. Cases were also more likely than healthy controls to report tenderness in multiple areas, including suprapubic, symphysis pubis, and posterior superior iliac spine, and on bimanual examination. No comparative findings were specific to biological sex, and no evidence of pudendal neuropathy was observed on extended examination of cases or controls. The extended genitourinary examination is an easily administered addition to the assessment of men and women during evaluation for UCPPS. Physical findings may help to better categorize patients with UCPPS into clinically relevant subgroups for optimal treatment. Published by Elsevier Inc.

Financial strain and birth weight: the mediating role of psychological distress.
Mitchell, Amanda M; Christian, Lisa M
2017-02-01
The effects of financial strain during pregnancy have received limited attention. In addition, data examining the pathways by which SES indicators contribute to birth weight are lacking. The objective of the current study was to examine the potential pathway of psychological distress in the relationship between financial strain and birth weight. Participants consisted of 138 pregnant women who completed measures assessing financial strain, depressive symptoms, pregnancy-specific distress, perceived stress, and general anxiety during pregnancy (mean gestational age = 18.5, SD = 7.2). Birth outcome data were obtained via medical record review. Simple and parallel mediation models were conducted using PROCESS. Simple mediation models showed that depressive symptoms (95% CI -24.65, -0.90) and pregnancy-specific distress (95% CI -37.31, -5.91), but not perceived stress (95% CI -31.17, 4.69) or anxiety (95% CI -25.84, 5.57), served as mediators in the relationship between financial strain and birth weight. When depressive symptoms and pregnancy-specific distress were included in the same mediation model, only pregnancy-specific distress remained significant. Financial strain was positively associated with all facets of psychological distress and negatively associated with birth weight during pregnancy. The current study demonstrated the mechanistic role of pregnancy-specific distress in the link between financial strain and birth weight in a racially diverse sample. Interventions targeting pregnancy-specific distress may mitigate the effects of financial strain on birth weight. Studies examining whether pregnancy-specific distress accounts for the relationship between other types of stressor exposures and birth weight would be informative.

The objective of this study was to assess the accuracy of palpating crepitus to diagnose rotator cuff tears. Seventy consecutive consenting patients who presented with shoulder pain and no previous imaging or surgery on the affected shoulder were prospectively enrolled during a 10-month period. A standardized patient history and examination, including the crepitus test, were recorded in addition to obtaining standard radiographs. Additional imaging after initial evaluation was performed with magnetic resonance imaging and interpreted by a musculoskeletal radiologist blinded to the examination findings. Statistical analysis was used to determine sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the crepitus test in the clinical diagnosis of a rotator cuff tear. Sixty-three patients had histories, examinations, and imaging studies available for analysis. The crepitus test had a sensitivity of 67%, specificity of 80%, PPV of 91%, and NPV of 43% for all types of rotator cuff tears. The sensitivity and specificity for full-thickness or high-grade partial tears was 82% and 73%, respectively; the PPV and NPV were 77% and 79%. Increasing age improved accuracy as the presence of crepitus in patients older than 55 years had a sensitivity of 76%, specificity of 100%, PPV of 100%, and NPV of 38%. The crepitus test has a favorable sensitivity, specificity, PPV, and NPV to assess the integrity of the rotator cuff and may be a useful examination in the clinical diagnosis of a rotator cuff tear.

Research has shown that depressed patients suffer from reduced autobiographical memory specificity (rAMS). This cognitive phenomenon is associated with the maintenance and recurrence of depressive symptoms. This pilot study aims to investigate the feasibility and effectiveness of a relatively new group-based intervention (Memory Specificity Training; MeST) that aims to reduce rAMS in an outpatient setting. Twenty-six depressed outpatients received MeST during the waiting period prior to psychotherapy. The Client Satisfaction Questionnaire (CSQ-8) was used to measure client satisfaction after the training. The Autobiographical Memory Test (AMT) was used to measure memory specificity before and after the training. Depressive symptoms were measured using the Beck Depression Inventory (BDI-II) and the Montgomery Asberg Depression Rating Scale (MADRS), before and after the training, and at a 3-month follow-up. Participants as well as trainers were positive about the use of MeST. Participants also showed an increase in memory specificity and a decrease in depressive symptoms. This study suggests that MeST is feasible in an outpatient setting, that it increases autobiographical memory specificity and that it may decrease depressive symptoms. A randomized controlled trial is recommended to examine MeST and its effects on autobiographical memory specificity, depressive symptoms and depressive relapse more extensively. Copyright © 2015 John Wiley & Sons, Ltd. Key Practitioner Message: Research suggests that modification of rAMS can advance recovery and reduce the chance of developing a depression relapse. However, most existing psychotherapies for depression do not include these specific interventions. This is the first study to show that MeST in an outpatient setting is feasible and can lead to an increase in autobiographical memory specificity and that it may decrease depressive symptoms. A larger scale randomized controlled trial is required to examine whether the addition of MeST to care as usual decreases depressive symptoms more effectively than care as usual without MeST, and to examine whether subgroups of patients benefit specifically from this intervention (e.g. patients with more severely decreased memory specificity).

The Achilles tendon (AT) is the strongest, largest, and most commonly ruptured tendon in the human body. Physical examination provides high sensitivity and specificity. Imaging studies are not recommended unless there are equivocal findings in the physical examination. Recent studies have shown that the risk of re-rupture is negated with implementation of functional rehabilitation protocols. Heterogeneity in study design makes conclusions on the specifics of functional rehabilitation protocols difficult; however, it is clear that early weight bearing and early controlled mobilization lead to better patient outcome and satisfaction in both surgically and conservatively treated populations.

This review is a historical look at work carried out over the past 50 years examining interactions of Toxoplasma with the host cell and attempts to focus on some of the seminal experiments in the field. This early work formed the foundation for more recent studies aimed at identifying the host and parasite factors mediating key Toxoplasma-host cell interactions. We focus especially on those studies that were performed in vitro and provide discussions of the following general areas: (i) establishment of the parasitophorous vacuole, (ii) the requirement of specific host cell molecules for parasite replication, (iii) the scenarios under which the host cell can resist parasite replication and/or persistence, (iv) host species-specific and host strain-specific responses to Toxoplasma infection, and (v) Toxoplasma-induced immune modulation.

We conducted this study to compare the specificity and sensitivity of the Ortolani and Barlow tests performed by dedicated examiners, and to ascertain the incidence of developmental dysplasia of the hip (DDH) in breech babies. A dedicated examiner underwent specific training and testing by a paediatric orthopaedic surgeon. Routine examiners were medical officers who had basic training in medical school and were briefly trained by their superiors. The dedicated examiner examined 170 babies. Thirty babies including 5 babies with positive tests (according to the dedicated examiner) were examined by a blinded routine examiner. RESULTS of Ortolani and Barlow tests on 30 babies were compared with ultrasound examination by blinded radiologist. Five babies had positive Ortolani and Barlow tests. The routine examiner did not detect positive Ortolani and Barlow tests. The incidence of positive Ortolani and Barlow tests among breech babies was 2.8%. Result of Ortolani and Barlow tests by dedicated hip screener were better than results performed by routine examiner. Ortolani and Barlow, Dedicated Examiner, Routine Examiner, Breech, Ultrasound.

The assessment of periodontitis and treatment needs is primarily based on clinical and radiographic examinations. Albeit effective in predicting treatment needs, these examinations are costly, time-consuming, and impractical for assessing population-level needs. The purpose of the present study is to evaluate a two-domain self-report questionnaire for rapid periodontitis screening. Six hundred white adult individuals, dentate or partially dentate and seeking dental therapy at a university clinic, underwent oral examination utilizing the full-mouth Community Periodontal Index of Treatment Needs (CPITN). To assess predictive value of self-reported periodontal measures (SRPMs) for periodontitis screening, four questions were formulated. Two questions aimed to assess "dentist-diagnosed periodontal disease" and two inquired about "self-assessed periodontitis." Multiple logistic regression models were used to construct receiver-operating characteristic curves, and predictor selection was performed via a forward stepwise selection process. Five hundred thirty-five volunteers with a mean age of 50.1 years elected to respond to SRPMs via telephone interview. After oral examination, 17.8% of participants were assessed as having CPITN = 4, representing compromised periodontal status. Sensitivity and specificity for correctly classifying compromised periodontal status ranged from 5.3% to 72.6%, and 87.8% to 99.5% for individual SRPMs. Sensitivity and specificity were increased when combining a measure of self-assessed periodontal disease and a measure of dentist-diagnosed disease as predictors. Addition of age and sex maximized sensitivity/specificity at 82.1%/82.2%. Diabetic status, smoking, and body mass index did not enhance the prediction. A two-domain self-report measure combining two self-report items with age and sex has good sensitivity and specificity for periodontitis screening in a white, university-based population. The proposed self-report measure can be valuable for periodontitis screening in resource-limited settings where gold standard clinical examination may not be pragmatic. Further validation studies are required to assess whether findings from this study are context-specific.

No study has examined the effectiveness of prescribing seating modifications according to the individual clinical presentation of people with low back pain (LBP). A dynamic, forward-inclined chair ('Back App') can reduce seated paraspinal muscle activation among pain-free participants. This study examined 21 participants whose LBP was specifically aggravated by prolonged sitting and was eased by standing. Low back discomfort (LBD) and overall body discomfort (OBD) were assessed every 15 min while participants sat for 1 h on both the dynamic, forward-inclined chair and a standard office chair. LBD increased significantly more (p = 0.005) on the standard office chair, with no significant difference (p = 0.178) in OBD between the chairs. The results demonstrate that, in a specific flexion-related subgroup of people with LBP, increased LBD during sitting can be minimised through modifying chair design. Mechanisms that minimise seated discomfort may be of relevance in LBP management, as part of a biopsychosocial management plan. This study examined low back discomfort (LBD) during a typing task among people with low back pain (LBP). Sitting on a dynamic, forward-inclined chair resulted in less seated LBD than sitting on a standard office chair. Further research is required to examine the long-term effectiveness of ergonomics interventions in LBP.

Honoring Identity Through Mealtimes in Chinese Canadian Immigrants.
Lam, Ivy T Y; Keller, Heather H
2015-11-01
Mealtimes are opportunities for social interactions and expressions of individual and family identity, and serve as a microcosm of the broader lives of families living with dementia. The Eating Together study and its resulting Life Nourishment Theory (LNT) explicated the importance of mealtimes for honouring individual and family identities in the context of dementia. This sub-study examined a specific ethnocultural group with cultural food-ways and caring expectations, to determine if the concept of honouring identity needed to be modified or extended. Using active interview techniques, two Cantonese speaking researchers completed dyad/triad family and individual interviews with six Chinese Canadian immigrant families, recruited from two service providers in a large, urban, multicultural city. This sub-study provided insight into the challenges and rewards of mealtimes for Chinese immigrant families with dementia in the community and specifically provided further insights into the honouring identity concept. Although LNT and specifically the honouring identity concept was generally confirmed in this group, some culturally-specific themes were also identified. This work serves as a basis for future studies examining the meaning and experience of mealtimes in specific cultural groups living with dementia. Such work would confirm if the LNT can be applied to specific ethnocultural groups as well as the general population living with dementia. © The Author(s) 2012.

Parenting is related to children's adjustment, but little research has examined the role of parenting in children's responses to disasters. This study describes parenting responses specific to the 9/11 terrorist attacks and examines pre-9/11 parenting, child temperament, and 9/11-specific parenting as predictors of children's posttraumatic stress (PTS) symptoms among children geographically distant from the attack locations. A community sample of children and parents (n = 137, ages 9-13 years) participating in an ongoing study were interviewed 1 month following 9/11. Parents reported engaging in a number of parenting responses following 9/11. Pre-9/11 acceptance and 9/11-specific, self-focused parental responses predicted PTS symptoms. Pre-9/11 parenting and temperament interacted to predict PTS symptoms, suggesting that parenting and temperament are important prospective predictors of children's responses to indirect exposure to disasters.

Antibodies against the protective antigen (PA) component of anthrax toxin play an important role in protection against disease caused by Bacillus anthracis. In this study, we examined defined combinations of PA-specific monoclonal antibodies for their ability to neutralize anthrax toxin in cell culture assays. We observed additive, synergistic, and antagonistic effects of the antibodies depending on the specific antibody combination examined and the specific assay used. Synergistic toxin-neutralizing antibody interactions were examined in more detail. We found that one mechanism that can lead to antibody synergy is the bridging of PA monomers by one antibody, with resultant bivalent binding of the second antibody. These results may aid in optimal design of new vaccines and antibody therapies against anthrax. PMID:22441391
The relative health benefits of different sexual activities.
Brody, Stuart
2010-04-01
Although many studies examine purported risks associated with sexual activities, few examine potential physical and mental health benefits, and even fewer incorporate the scientifically essential differentiation of specific sexual behaviors. This review provides an overview of studies examining potential health benefits of various sexual activities, with a focus on the effects of different sexual activities. Review of peer-reviewed literature. Findings on the associations between distinct sexual activities and various indices of psychological and physical function. A wide range of better psychological and physiological health indices are associated specifically with penile-vaginal intercourse. Other sexual activities have weaker, no, or (in the cases of masturbation and anal intercourse) inverse associations with health indices. Condom use appears to impair some benefits of penile-vaginal intercourse. Only a few of the research designs allow for causal inferences. The health benefits associated with specifically penile-vaginal intercourse should inform a new evidence-based approach to sexual medicine, sex education, and a broad range of medical and psychological consultations.
Mexican oil and dependent development

The developmet of Mexico's enormous hydrocarbon resources during the latter part of the 1970's provides an opportunity to examine the impact of Mexico's dependent-state status upon the use of the resource. Specifically, this study examines the hypothesis, drawn from the dependency literature, that the development of this resource within the context of dependency would lead to a greater internationalization of the Mexican economy and, in general, a deepening of Mexico's dependence rather than a lessening of that dependence as Mexico's political leaders suggest. The study also examines the impact of hydrocarbon development upon the growth of the Mexican state andmore » state capitalism. Finally, the study examines the extent to which Mexico has sought to and has been able to modify the conditions of its dependence at the level of international exchange in the specific areas of trade, labor, and energy. Has the ''oil weapon'' been sufficiently powerful to modify substantially and fundamentally the terms of Mexico's dependence as some would argue should be able to do and as Mexico's leaders believed it would. Essentially, the study finds that Mexico's dependence has been exacerbated by the program of hydrocarbon development. Not only has the specific profile of oil, gas, and petrochemicals development been substantially impacted upon by Mexico's dependence, but the program for general economic development based upon the utilization of new oil revenues initiated a new era of dependent development for Mexico.« less

The aim of this study was to evaluate the diagnostic properties of urine Gram stain and urine microscopic examination for screening for urinary tract infection (UTI), and to perform an additional cost utility analysis. This descriptive study was performed on 95 urine samples sent for urine culture to the Department of Microbiology, Faculty of Medicine, Chulalongkorn University. The first part of the study was to determine the diagnostic properties of two screening tests (urine Gram stain and urine microscopic examination). Urine culture was set as the gold standard and the results from both methods were compared to this. The second part of this study was to perform a cost utility analysis. The sensitivity of urine Gram stain was 96.2%, the specificity 93.0%, the positive predictive value 94.3% and the negative predictive value 95.2%. False positives occurred with a frequency of 7.0% and false negatives 3.8%. For the microscopic examination, the sensitivity was 65.4%, specificity 74.4%, positive predictive value 75.6% and negative predictive value 64.0%. False positives occurred with a frequency of 25.6% and false negatives 34.6%. Combining urine Gram stain and urine microscopic examination, the sensitivity was 98.1%, specificity 74.4%, positive predictive value 82.3% and negative predictive value 97.0%. False positives occurred with a frequency of 25.6% and false negatives 1.9%. However, the cost per utility of the combined method was higher than either urine microscopic examination or urine Gram stain alone. Urine Gram stain provided the lowest cost per utility. Economically, urine Gram stain is the proper screening tool for presumptive diagnosis of UTI.

To evaluate the sensitivity, specificity and reliability of the gait, arms, legs and spine (GALS) examination to detect signs and symptoms of rheumatoid arthritis when used by physiotherapy students and physiotherapists. Two physiotherapy students and two physiotherapists were trained to perform the GALS examination by viewing an instructional DVD and attending a workshop. Two rheumatologists familiar with the GALS examination also participated in the workshop. All healthcare professionals performed the GALS examination on 25 participants with rheumatoid arthritis recruited through a rheumatology practice and 23 participants without any arthritides recruited from a primary care centre. Each participant was assessed by one rheumatologist, one physiotherapist and one physiotherapy student. Abnormalities of gait, arms, legs and spine, including their location and description, were recorded, along with whether or not a diagnosis of rheumatoid arthritis was suspected. Healthcare professionals understood the study's objective to be their agreement on GALS findings and were unaware that half of the participants had rheumatoid arthritis. Sensitivity, specificity and likelihood ratios were calculated to determine the ability of the GALS examination to screen for rheumatoid arthritis. Using rheumatologists' findings on the study day as the standard for comparison, sensitivity and specificity were 71 to 86% and 69 to 93%, respectively. Positive likelihood ratios ranged from 2.74 to 10.18, while negative likelihood ratios ranged from 0.21 to 0.38. The GALS examination may be a useful tool for physiotherapists to rule out rheumatoid arthritis in a direct access setting. Differences in duration and type of experience of each healthcare professional may contribute to the variation in results. The merits of introducing the GALS examination into physiotherapy curricula and practice should be explored. Copyright © 2010 Chartered Society of Physiotherapy. Published by Elsevier Ltd.

Prior studies consistently report that men's genital responses correspond to their sexual activity interests (consenting vs. coercive sex) whereas women's responses do not. For women, however, these results may be confounded by the sexual activities studied and lack of suitable controls. We examined the subjective and genital arousal responses of men and women with conventional (22 men and 15 women) or masochistic sexual interests (16 men and 17 women) to narratives describing conventional sex or masochistic sex. The aims of the studies were twofold: (1) to examine whether gender differences in the specificity of sexual arousal previously observed for gender also exist for sexual activity interests; and (2) to examine whether men and women with masochistic sexual interests demonstrate specificity of sexual response for their preferred sexual activities. Surprisingly, the pattern of results was very similar for men and women. Both men and women with conventional sexual interests (WCI) reported more sexual arousal, and responded more genitally, to conventional than to masochistic sex, demonstrating specificity of sexual arousal for their preferred sexual activities. Despite showing specificity for conventional sexual activities, the genital responses of WCI were still gender nonspecific. In contrast, women and men with masochistic sexual interests demonstrated nonspecific subjective and genital responses to conventional and masochistic sex. Indices of genital and subjective sexual arousal to masochistic versus conventional stimuli were positively and significantly correlated with self-reported thoughts, fantasies, interests, and behaviors involving masochism. The results suggest that gender similarities in the specificity of sexual arousal for sexual activity exist despite consistent gender differences in the specificity of sexual arousal for gender.

The Effect of Interruptions on Part 121 Air Carrier Operations
NASA Technical Reports Server (NTRS)
Damos, Diane L.
1998-01-01
The primary purpose of this study was to determine the relative priorities of various events and activities by examining the probability that a given activity was interrupted by a given event. The analysis will begin by providing frequency of interruption data by crew position (captain versus first officer) and event type. Any differences in the pattern of interruptions between the first officers and the captains will be explored and interpreted in terms of standard operating procedures. Subsequent data analyses will focus on comparing the frequency of interruptions for different types of activities and for the same activities under normal versus emergency conditions. Briefings and checklists will receive particular attention. The frequency with which specific activities are interrupted under multiple- versus single-task conditions also will be examined; because the majority of multiple-task data were obtained under laboratory conditions, LOFT-type tapes offer a unique opportunity to examine concurrent task performance under 'real-world' conditions. A second purpose of this study is to examine the effects of the interruptions on performance. More specifically, when possible, the time to resume specific activities will be compared to determine if pilots are slower to resume certain types of activities. Errors in resumption or failures to resume specific activities will be noted and any patterns in these errors will be identified. Again, particular attention will be given to the effects of interruptions on the completion of checklists and briefings. Other types of errors and missed events (i.e., the crew should have responded to the event but did not) will be examined. Any methodology using interruptions to examine task prioritization must be able to identify when an interruption has occurred and describe the ongoing activities that were interrupted. Both of these methodological problems are discussed In detail in the following section,

Temperaments have been described with respect to their adaptive roles. Thus, depressive traits seem to increase sensitivity to suffering, cyclothymic traits appear relevant to creativity, and hyperthymic traits have been implicated in territoriality and leadership and more generally in active pursuits. The temperaments of 1548 candidates applying to become a cadet officer in the Italian air force, who had taken the 2005 entrance examination, were compared with deviant and non-deviant peers. At a psychological level, we also compared those who had applied to become a cadet officer with other applicants who had failed in a previous entrance examination and with applicants who had passed or failed to pass the specific psychological entrance examination. Applicants who took the entrance examination are more hyperthymic than their peers, regardless of any concurrent psychosocial deviance (i.e. drug addiction). The specificity of this correlation is confirmed by the fact that applicants who made a second attempt to pass the entrance examination after an initial failure were more hyperthymic than first-time applicants. Similarly, success in specific psychological admission tests is related to the same temperamental profiles, since those who prove to be psychologically fit are more hyperthymic. The inverse relationship emerges from an examination of other temperamental scales, which are better represented in controls (non-applicants), or other applicants making their first attempt at admission, or those who were excluded due to psychological flaws. In the present study, extremely high scores on the hyperthymic scale combined with extremely low ones in the cyclothymic scale seem to correspond to the specific temperament profile and to the highest likelihood of success in those applying to become a cadet officer in the Italian air force.

Specific phobias are prevalent and often disabling anxiety disorders. The present review examines relevant investigations that have been published during the last 2 years on major aspects of this group of disorders. Recent studies have come mainly from epidemiology, brain imagery and cognitive-behavioral therapy, including virtual reality exposure therapy. Studies published in the last 2 years confirm the high prevalence of specific phobias in the general population and provide new insights into the mechanisms underlying the fear reaction after exposure to a phobic stimulus.

Utilization and value of personal digital assistants on an epidemiology final examination.
Lawler, Frank H; Cacy, Jim
2005-01-01
The utility of personal digital assistants (PDAs) in basic science medical education is uncertain. Student outcomes on an epidemiology course final examination for academic years 2003 and 2004 were examined. Students were given permission to use PDAs on the final examination, and self-selected whether these instruments were used. Performance on the examination based on use of a PDA and whether students thought it was useful for the examination was compared. A total of 389 students took the final examination, with an 88% response rate to the survey questions. No statistically significant differences were found on final examination scores. No trends toward significance were found on analyses of the total examination, specific topical domains, or on specific questions where a PDA might be expected to be especially useful. From this study, it can be concluded that use of PDAs and whether students thought they might be helpful had no measurable effect on performance on an epidemiology final examination. Further delineation of the possible use of PDAs in a basic science course and on the final examination is indicated.

The present study examines the interplay between cognitive deficits and emotional context in obsessive-compulsive disorder (OCD) and social phobia (SP). Specifically, this study examines whether the inflexible use of efficient learning strategies in an emotional context underlies impairments in probabilistic classification learning (PCL) in OCD, and whether PCL impairments are specific to OCD. Twenty-three participants with OCD, 30 participants with SP and 30 healthy controls completed a neutral and an OCD-specific PCL task. OCD participants failed to adopt efficient learning strategies and showed fewer beneficial strategy switches than controls only in an OCD-specific context, but not in a neutral context. Additionally, OCD participants did not show any explicit memory impairments. Number of beneficial strategy switches in the OCD-specific task mediated the difference in PCL performance between OCD and control participants. Individuals with SP were impaired in both PCL tasks. In contrast to neuropsychological models postulating general cognitive impairments in OCD, the present findings suggest that it is the interaction between cognition and emotion that is impaired in OCD. Specifically, activated disorder-specific fears may impair the flexible adoption of efficient learning strategies and compromise otherwise unimpaired PCL. Impairments in PCL are not specific to OCD.

This study examines barriers to economic self-sufficiency among a panel of 219 former Supplemental Security Income (SSI) drug addiction and alcoholism (DA&A) recipients following elimination of DA&A as an eligibility category for SSI disability benefits. Study participants were comprehensively surveyed at six measurement points following the policy change. Generalized estimating equations were used to examine full-sample and gender-specific barriers to economic self-sufficiency. Results indicate that access to transportation, age, and time are the strongest predictors of achieving self-sufficiency for both men and women leaving the welfare system. Gender-specific barriers are also identified. Future research needs to assess the generalizability of these results to other public assistance recipients. PMID:21625301

The age neutrality of the Social Communication Questionnaire (SCQ) was examined as a common screener for ASD. Mixed findings have been reported regarding the recommended cutoff score's ability to accurately classify an individual as at-risk for autism spectrum disorder (ASD) (sensitivity) versus accurately classifying an individual as not at-risk for ASD (specificity). With a sample from the National Database for Autism Research, this study examined the SCQ's sensitivity versus specificity. Analyses indicated that the actual sensitivity and specificity scores were lower than initially reported by the creators of the SCQ.

Sedentary behavior and residual-specific mortality
Loprinzi, Paul D.; Edwards, Meghan K.; Sng, Eveleen; Addoh, Ovuokerie
2016-01-01
Background: The purpose of this study was to examine the association of accelerometer-assessed sedentary behavior and residual-specific mortality. Methods: Data from the 2003-2006 National Health and Nutrition Examination Survey (NHANES) were used (N = 5536), with follow-up through 2011. Sedentary behavior was objectively measured over 7 days via accelerometry. Results: When expressing sedentary behavior as a 60 min/day increase, the hazard ratio across the models ranged from 1.07-1.40 (P < 0.05). There was evidence of an interaction effect between sedentary behavior and total physical activity on residual-specific mortality (Hazard ratiointeraction [HR] = 0.9989; 95% CI: 0.9982-0.9997; P = 0.008). Conclusion: Sedentary behavior was independently associated with residual-specific mortality. However, there was evidence to suggest that residual-specific mortality risk was a function of sedentary behavior and total physical activity. These findings highlight the need for future work to not only examine the association between sedentary behavior and health independent of total physical activity, but evaluate whether there is a joint effect of these two parameters on health.

We sought to summarize accuracy of physical examination, imaging, and Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score in diagnosis of necrotizing soft tissue infection (NSTI) in adults with a soft tissue infection clinically concerning for NSTI. NSTI is a life-threatening diagnosis. Delay to diagnosis and surgical management is associated with increased mortality. We searched 6 databases from inception through November 2017. We included English-language studies reporting diagnostic accuracy of testing or LRINEC Score. Outcome was NSTI confirmed by surgery or histopathology. Two reviewers screened all citations and extracted data independently. Summary measures were obtained from the Hierarchical Summary Receiver Operating Characteristic model. From 2,290 citations, we included 23 studies (n = 5982). Of physical examination signs, pooled sensitivity and specificity for fever was 46.0% and 77.0% respectively, for hemorrhagic bullae 25.2% and 95.8%, and for hypotension 21.0% and 97.7%. Computed tomography (CT) had sensitivity of 88.5% and specificity of 93.3%, while plain radiography had sensitivity of 48.9% and specificity of 94.0%. Finally, LRINEC ≥ 6 had sensitivity of 68.2% and specificity of 84.8%, while LRINEC ≥ 8 had sensitivity of 40.8% and specificity of 94.9%. Absence of any 1 physical examination feature (eg, fever or hypotension) is not sufficient to rule-out NSTI. CT is superior to plain radiography. LRINEC had poor sensitivity, and should not be used to rule-out NSTI. Given the poor sensitivity of these tests, a high clinical suspicion warrants early surgical consultation for definitive diagnosis and management.
Effects of political and military traumas on children: the Palestinian case.
Baker, A; Shalhoub-Kevorkian, N
1999-12-01
Social scientists have long recognized that individuals subjected to traumatic events associated with military and political conflict experience dire psychological consequences. The systematic study of this phenomenon, however, could be considered a nascent event. Research on the psychological sequel of traumatic events (traumatology) is well-rooted in the recognition and development of posttraumatic stress disorder as a separate psychological disorder category. The early studies in this field focused mainly on adult populations. With the recent advent of involvement of children in military conflicts such as in Africa (e.g., Mozambique), the Middle East (e.g., Palestine, Lebanon), and Southeast Asia (e.g., Cambodia), psychologists have taken a keen interest in examining the psychological effects such conflicts reap on children. Hence, a growing but modest body of literature has been amassed within the past 20 years on the subject. This article is an attempt to synthesize this literature in order to examine the universal and culture-specific correlates of political and military trauma. Specifically, the article will focus on the psychological symptoms children display following their exposure to such traumatic events. Special emphasis will be placed on anxiety, phobic, psychosomatic, and depressive symptoms. More importantly, however, an examination will be made to ascertain which factors (e.g., psychosocial, cultural, and political) serve to shield (protect) or predispose (vulnerability) children to psychological dysfunction. Furthermore, the analyses presented will be gender specific. The article will attempt to delineate a paradigm that explains the relationship between trauma, culture, and personality. Although the article will examine studies from various regions, specific emphasis will be placed on the Palestinian experience.

To examine the event-specific relationship between alcohol intoxication and nighttime tobacco smoking among college bar patrons. In this secondary analysis of existing data, we examined event-specific associations between self-report measures of tobacco smoking and breath alcohol concentration (BrAC) readings obtained from 424 patrons exiting on-premise drinking establishments. In a multivariable logistic regression analysis, acute alcohol intoxication was positively associated with same-night incidents of smoking tobacco, adjusting for the effects of established smoking practices and other potential confounders. This investigation is the first known study using data collected in an on-premise drinking setting to link alcohol intoxication to specific incidents of tobacco smoking.

Background Computer-aided dermoscopy using artificial neural networks has been reported to be an accurate tool for the evaluation of pigmented skin lesions. We set out to determine the sensitivity and specificity of a computer-aided dermoscopy system for diagnosis of melanoma in Iranian patients. Methods We studied 122 pigmented skin lesions which were referred for diagnostic evaluation or cosmetic reasons. Each lesion was examined by two clinicians with naked eyes and all of their clinical diagnostic considerations were recorded. The lesions were analyzed using a microDERM® dermoscopy unit. The output value of the software for each lesion was a score between 0 and 10. All of the lesions were excised and examined histologically. Results Histopathological examination revealed melanoma in six lesions. Considering only the most likely clinical diagnosis, sensitivity and specificity of clinical examination for diagnosis of melanoma were 83% and 96%, respectively. Considering all clinical diagnostic considerations, the sensitivity and specificity were 100% and 89%. Choosing a cut-off point of 7.88 for dermoscopy score, the sensitivity and specificity of the score for diagnosis of melanoma were 83% and 96%, respectively. Setting the cut-off point at 7.34, the sensitivity and specificity were 100% and 90%. Conclusion The diagnostic accuracy of the dermoscopy system was at the level of clinical examination by dermatologists with naked eyes. This system may represent a useful tool for screening of melanoma, particularly at centers not experienced in the field of pigmented skin lesions. PMID:16000171

Background. There are relatively few studies published examining the sensitivity and specificity of potassium hydroxide (KOH) smear and fungal culture examination of tinea pedis. Objective. To evaluate the sensitivity and specificity of KOH smear and fungal culture for diagnosing tinea pedis. Methods. A pooled analysis of data from five similarly conducted bioequivalence trials for antifungal drugs was performed. Data from 460 patients enrolled in the vehicle arms of these studies with clinical diagnosis of tinea pedis supported by positive fungal culture were analyzed 6 weeks after initiation of the study to determine the sensitivity and specificity of KOH smear and fungal culture. Results. Using clinical assessment as the gold standard, the sensitivities for KOH smear and culture were 73.3% (95% CI: 66.3 to 79.5%) and 41.7% (34.6 to 49.1%), respectively. The respective specificities for culture and KOH smear were 77.7% (72.2 to 82.5%) and 42.5% (36.6 to 48.6%). Conclusion. KOH smear and fungal culture are complementary diagnostic tests for tinea pedis, with the former being the more sensitive test of the two, and the latter being more specific. PMID:20672004
Muscle Activation During ACL Injury Risk Movements in Young Female Athletes: A Narrative Review.
Bencke, Jesper; Aagaard, Per; Zebis, Mette K
2018-01-01
Young, adolescent female athletes are at particular high risk of sustaining a non-contact anterior cruciate ligament (ACL) injury during sport. Through the last decades much attention has been directed toward various anatomical and biomechanical risk factors for non-contact ACL injury, and important information have been retrieved about the influence of external loading factors on ACL injury risk during given sports-specific movements. However, much less attention has been given to the aspect of neuromuscular control during such movements and only sparse knowledge exists on the specific muscle activation patterns involved during specific risk conditions. Therefore, the aim of this narrative review was (1) to describe anatomical aspects, strength aspects and biomechanical aspects relevant for the understanding of ACL non-contact injury mechanisms in young female athletes, and (2) to review the existing literature on lower limb muscle activation in relation to risk of non-contact ACL-injury and prevention of ACL injury in young female athletes. Studies investigating muscle activity patterns associated with sports-specific risk situations were identified, comprising cohort studies, intervention studies and prospective studies. Based on the retrieved studies, clear gender-specific differences in muscle activation and coordination were identified demonstrating elevated quadriceps activity and reduced hamstring activity in young female athletes compared to their male counterparts, and suggesting young female athletes to be at elevated risk of non-contact ACL injury. Only few studies ( n = 6) examined the effect of preventive exercise-based intervention protocols on lower limb muscle activation during sports-specific movements. A general trend toward enhanced hamstring activation was observed during selected injury risk situations (e.g., sidecutting and drop landings). Only a single study examined the association between muscle activation deficits and ACL injury risk, reporting that low medial hamstring activation and high vastus lateralis activation prior to landing was associated with an elevated incidence of ACL-injury. A majority of studies were performed in adult female athletes. The striking paucity of studies in adolescent female athletes emphasizes the need for increased research activities to examine of lower limb muscle activity in relation to non-contact ACL injury in this high-risk athlete population.

Klatt, Edward C
2014-01-01
General and subject specific practice examinations for students in health sciences studying pathology were placed onto a free public internet web site entitled web path and were accessed four clicks from the home web site menu. Multiple choice questions were coded into. html files with JavaScript functions for web browser viewing in a timed format. A Perl programming language script with common gateway interface for web page forms scored examinations and placed results into a log file on an internet computer server. The four general review examinations of 30 questions each could be completed in up to 30 min. The 17 subject specific examinations of 10 questions each with accompanying images could be completed in up to 15 min each. The results of scores and user educational field of study from log files were compiled from June 2006 to January 2014. The four general review examinations had 31,639 accesses with completion of all questions, for a completion rate of 54% and average score of 75%. A score of 100% was achieved by 7% of users, ≥90% by 21%, and ≥50% score by 95% of users. In top to bottom web page menu order, review examination usage was 44%, 24%, 17%, and 15% of all accessions. The 17 subject specific examinations had 103,028 completions, with completion rate 73% and average score 74%. Scoring at 100% was 20% overall, ≥90% by 37%, and ≥50% score by 90% of users. The first three menu items on the web page accounted for 12.6%, 10.0%, and 8.2% of all completions, and the bottom three accounted for no more than 2.2% each. Completion rates were higher for shorter 10 questions subject examinations. Users identifying themselves as MD/DO scored higher than other users, averaging 75%. Usage was higher for examinations at the top of the web page menu. Scores achieved suggest that a cohort of serious users fully completing the examinations had sufficient preparation to use them to support their pathology education.

Cancer patients can experience work-specific cognitive symptoms post return to work (RTW). The study aims to: 1) describe the course of work-specific cognitive symptoms in the first 18 months post RTW, and 2) examine the associations of work characteristics, fatigue and depressive symptoms with work-specific cognitive symptoms over time. This study used data from the 18-months longitudinal "Work Life after Cancer" cohort. The Cognitive Symptom Checklist-Work, Dutch Version (CSC-W DV) was used to measure work-specific cognitive symptoms. Linear mixed models were performed to examine the course of work-specific cognitive symptoms during 18 months follow-up; linear regression analyses with generalised estimating equations (GEE) were used to examine associations over time. Working cancer patients diagnosed with different cancer types were included (n=378). Work-specific cognitive symptoms were stable over 18 months. At baseline, cancer patients reported more working memory symptoms (M=31.9, CI=23.1, 26.4) compared to executive function symptoms (M=19.3; CI=17.6, 20.9). Cancer patients holding a job with both manual and non-manual tasks reported less work-specific cognitive symptoms (unstandardized regression coefficient b=-4.80; CI=-7.76, -1.83) over time, compared to cancer patients with a non-manual job. Over time, higher depressive symptoms were related to experiencing more overall work-specific cognitive symptoms (b=1.27; CI=1.00, 1.55) and a higher fatigue score was related to more working memory symptoms (b=0.13; CI=0.04, 0.23). Job type should be considered when looking at work-specific cognitive symptoms over time in working cancer patients. To reduce work-specific cognitive symptoms, interventions targeted at fatigue and depressive symptoms might be promising. This article is protected by copyright. All rights reserved.

Several studies have demonstrated skills transfer after virtual reality (VR) simulation training in laparoscopic surgery. However, the impact of VR simulation training on transfer of skills related to laparoscopic colectomy remains not investigated. The present study aimed at determining the impact of VR simulation warm-up on performance during laparoscopic colectomy in the porcine model. Fourteen residents naive to laparoscopic colectomy as surgeons were randomly assigned in block to two groups. Seven trainees completed a 2-h VR simulator training in the laparoscopic sigmoid colectomy module (study group). The remaining seven surgeons (control group) underwent no intervention. On the same day, all participants performed a sigmoid colectomy with anastomosis on a pig. All operations were video recorded. Two board-certified expert colorectal surgeons independently assessed performance during the colectomy on the swine. Examiners were blinded to group assignment. The two examiners used a previously validated clinical instrument specific to laparoscopic colectomy. The primary outcome was the generic and specific skills score values. Surgeons undergoing short-duration training on the VR simulator performed significantly better during laparoscopic colectomy on the pig regarding general and specific technical skills evaluation. The average score of generic skills was 17.2 (16.5-18) for the control group and 20.1 (16.5-22) for the study group (p = 0.002). The specific skills average score for the control group was 20.2 (19-21.5) and 24.2 (21-27.5) for the study group (p = 0.001). There was acceptable concordance (Kendall's W) regarding the video assessment of generic (W = 0.78) and specific skills (W = 0.84) between the two examiners. A single short-duration VR simulator practice positively impacted surgeons' generic and specific skills performance required to accomplish laparoscopic colectomy in the swine model.

Introduction: The present study examines the question whether the selection of dental students should be based solely on average school-leaving grades (GPA) or whether it could be improved by using a subject-specific aptitude test. Methods: The HAM-Nat Natural Sciences Test was piloted with freshmen during their first study week in 2006 and 2007. In 2009 and 2010 it was used in the dental student selection process. The sample size in the regression models varies between 32 and 55 students. Results: Used as a supplement to the German GPA, the HAM-Nat test explained up to 12% of the variance in preclinical examination performance. We confirmed the prognostic validity of GPA reported in earlier studies in some, but not all of the individual preclinical examination results. Conclusion: The HAM-Nat test is a reliable selection tool for dental students. Use of the HAM-Nat yielded a significant improvement in prediction of preclinical academic success in dentistry.

With an increasing focus on biomarkers in dementia research, illustrating the role of neuropsychological assessment in detecting mild cognitive impairment (MCI) and Alzheimer’s dementia (AD) is important. This systematic review and meta-analysis, conducted in accordance with PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) standards, summarizes the sensitivity and specificity of memory measures in individuals with MCI and AD. Both meta-analytic and qualitative examination of AD versus healthy control (HC) studies (n = 47) revealed generally high sensitivity and specificity (≥ 80% for AD comparisons) for measures of immediate (sensitivity = 87%, specificity = 88%) and delayed memory (sensitivity = 89%, specificity = 89%), especially those involving word-list recall. Examination of MCI versus HC studies (n = 38) revealed generally lower diagnostic accuracy for both immediate (sensitivity = 72%, specificity = 81%) and delayed memory (sensitivity = 75%, specificity = 81%). Measures that differentiated AD from other conditions (n = 10 studies) yielded mixed results, with generally high sensitivity in the context of low or variable specificity. Results confirm that memory measures have high diagnostic accuracy for identification of AD, are promising but require further refinement for identification of MCI, and provide support for ongoing investigation of neuropsychological assessment as a cognitive biomarker of preclinical AD. Emphasizing diagnostic test accuracy statistics over null hypothesis testing in future studies will promote the ongoing use of neuropsychological tests as Alzheimer’s disease research and clinical criteria increasingly rely upon cerebrospinal fluid (CSF) and neuroimaging biomarkers.

Clinical examination of the shoulder joint has gained attention as clinicians aim to use an evidence-based examination of the biceps tendon, with the desire for a proper diagnosis while minimizing costly imaging procedures. The purpose of this study is to create a decision tree analysis that enables the development of a clinical algorithm for diagnosing long head of biceps (LHB) pathology. A literature review of Level I and II diagnostic studies was conducted to extract characteristics of clinical tests for LHB pathology through a systematic review of PubMed, Medline, Ovid, and Cochrane Review databases. Tests were combined in series and parallel to determine sensitivities and specificities, and positive and negative likelihood ratios were determined for each combination using a subjective pretest probability. The "gold standard" for diagnosis in all included studies was arthroscopy or arthrotomy. The optimal testing modality was use of the uppercut test combined with the tenderness to palpation of the biceps tendon test. This combination achieved a sensitivity of 88.4% when performed in parallel and a specificity of 93.8% when performed in series. These tests used in combination optimize post-test probability accuracy greater than any single individual test. Performing the uppercut test and biceps groove tenderness to palpation test together has the highest sensitivity and specificity of known physical examinations maneuvers to aid in the diagnosis of LHB pathology compared with diagnostic arthroscopy (practical, evidence-based, comprehensive examination). A decision tree analysis aides in the practical, evidence-based, comprehensive examination diagnostic accuracy post-testing based on the ordinal scale pretest probability.

To examine the chronic illness literature and evaluate the impact on single parenting and children and adolescents with chronic illness. We conducted literature reviews of relevant research pertaining to single-parent families on PubMed, Medline, and PsychINFO and also surveyed pertinent book chapters and all of the articles from the Journal of Pediatric Psychology since 1987 for articles, specifically examining the potential associations of single (lone) parenting versus two-parent households on children's psychosocial functioning and the impact of the child's illness on caregiver functioning. While the literature has examined and discussed the stressors associated with parenting a child with an illness, including the impact of illness on finances, family roles, and caregiver burden, few studies have examined single parents of children and adolescents with chronic illnesses and related stressors stemming from being a lone caregiver. There is a dearth of studies examining the association between lone parenting and psychosocial functioning among children and adolescents with chronic illnesses. Specific questions necessitating future investigation are summarized and recommendations are made for future research in this important area of inquiry.
Self-determination and sexual experience in dating relationships.
Brunell, Amy B; Webster, Gregory D
2013-07-01
The authors propose the Model of Self-Determined Sexual Motivation to examine sexual motivation in dating relationships using a Self-Determination Theory (SDT) framework. This model predicted that sexual need satisfaction would mediate the association between self-determined sexual motives and the outcome variables of psychological well-being and relational quality. Three studies tested this model. Study 1 was a cross-sectional study that investigated sexual motivation in dating relationships. Study 2 was an event-contingent interaction record study that investigated specific sexual interactions over 2 weeks. Study 3 combined event- and interval-contingent methods using a daily diary to examine the model for both partners to enable examination of actor and partner effects. Discussion section focuses on the power of examining SDT in the sexual domain.

This study describes gender-specific patterns of drug use among active rural stimulant users and examines religiosity and spirituality as factors that may be related to stimulant use among males and females. The study includes a sample of 225 active rural stimulant users from Kentucky who were recruited using respondent driven sampling and completed face-to-face interviews. Findings suggest gender specific patterns among active rural stimulant users, with females reporting more amphetamine use. In addition, bivariate findings indicate that there is an inverse relationship between spirituality, religiosity, and stimulant use (specifically methamphetamine and amphetamine use), particularly for males. However, when further examining this relationship in multivariate models controlling for age and race, few significant findings were noted for spirituality and religiosity in predicting gender-specific stimulant use patterns. These findings suggest that treatment interventions that incorporate spirituality and religiosity should not only be gender specific, but should also target clients differentially. Findings on the degree of reported spirituality and religiosity also suggest that religious and/or faithbased organizations could be utilized for drug use interventions for rural stimulant users.

Pregnancy-specific anxiety is an important risk factor for adverse pregnancy outcomes. It is therefore needed to gain insight in which women are at risk for elevated levels (> 85th percentile) of pregnancy-specific anxiety. Additionally, given that unhealthy behaviour has been suggested as a possible pathway linking pregnancy-specific anxiety to adverse pregnancy outcomes, it is important to examine whether higher levels of pregnancy-specific anxiety are associated with negative health-related behaviours (smoking, alcohol use and too much weight gain). Using a study sample of 4541 low-risk pregnant women who filled in the Pregnancy Related Anxiety Questionnaire-Revised (PRAQ-R), we first examined which socio-demographic, pregnancy-related and psychological background characteristics were significantly associated with a PRAQ-R score above the 85th percentile. Secondly, we examined the association between pregnancy-specific anxiety and self-reported health-related behaviours (smoking, alcohol use and too much weight gain) while controlling for significant background characteristics. For both research questions, backward regression analysis was applied. Results showed that nulliparity (OR=2.33, 95% confidence interval (CI)=1.97-2.77), anxious or depressed mood (OR=3.29, 95% CI=2.74-3.94) and non-Dutch ethnicity, especially Turkish (OR=3.47, 95% CI=2.16-5.59) or Moroccan (OR=2.97, 95% CI=1.84-4.81), were most strongly associated with elevated pregnancy-specific anxiety levels. Women with higher pregnancy-specific anxiety levels were more likely to gain too much weight during pregnancy (odds ratio (OR) linear term=1.49, 95% CI=1.21-1.83), while both very low and high levels of pregnancy-specific anxiety were associated with smoking (OR linear term=0.13, 95% CI=0.04-0.45, OR quadratic term=1.81, 95% CI=1.32-2.47). No association with alcohol use was found. In conclusion, our results show nulliparity, anxious or depressed mood and non-Dutch ethnicity as three major vulnerability factors for elevated levels of pregnancy-specific anxiety. Furthermore, our results show an association between pregnancy-specific anxiety and negative health-related behaviours, which is worth examining in future studies. Copyright © 2017 Elsevier Inc.

Findings from prior research have consistently indicated significant associations between self-regulation and externalizing behaviors. Significant associations have also been reported between children's language skills and both externalizing behaviors and self-regulation. Few studies to date, however, have examined these relations longitudinally, simultaneously, or with respect to unique clusters of externalizing problems. The current study examined the influence of preschool self-regulation on general and specific externalizing behavior problems in early elementary school and whether these relations were independent of associations between language, self-regulation, and externalizing behaviors in a sample of 815 children (44% female). Additionally, given a general pattern of sex differences in the presentations of externalizing behavior problems, self-regulation, and language skills, sex differences for these associations were examined. Results indicated unique relations of preschool self-regulation and language with both general externalizing behavior problems and specific problems of inattention. In general, self-regulation was a stronger longitudinal correlate of externalizing behavior for boys than it was for girls, and language was a stronger longitudinal predictor of hyperactive/impulsive behavior for girls than it was for boys.

High comorbidity rates among emotional disorders have led researchers to examine transdiagnostic factors that may contribute to shared psychopathology. Bifactor models provide a unique method for examining transdiagnostic variables by modelling the common and unique factors within measures. Previous findings suggest that the bifactor model of the Depression Anxiety and Stress Scale (DASS) may provide a method for examining transdiagnostic factors within emotional disorders. This study aimed to replicate the bifactor model of the DASS, a multidimensional measure of psychological distress, within a US adult sample and provide initial estimates of the reliability of the general and domain-specific factors. Furthermore, this study hypothesized that Worry, a theorized transdiagnostic variable, would show stronger relations to general emotional distress than domain-specific subscales. Confirmatory factor analysis was used to evaluate the bifactor model structure of the DASS in 456 US adult participants (279 females and 177 males, mean age 35.9 years) recruited online. The DASS bifactor model fitted well (CFI = 0.98; RMSEA = 0.05). The General Emotional Distress factor accounted for most of the reliable variance in item scores. Domain-specific subscales accounted for modest portions of reliable variance in items after accounting for the general scale. Finally, structural equation modelling indicated that Worry was strongly predicted by the General Emotional Distress factor. The DASS bifactor model is generalizable to a US community sample and General Emotional Distress, but not domain-specific factors, strongly predict the transdiagnostic variable Worry.

Alcohol-specific communication, a direct conversation between an adult and an adolescent regarding alcohol use, contains messages about alcohol relayed from the adult to the child. The current study examined the construct of alcohol-specific communication and the effect of messages on adolescent alcohol use and alcohol-related consequences. Parent-adolescent dyads were assessed biannually for 3 years (grades 9-11 at wave 6) to examine these relations in a large longitudinal study of adolescents initially in grades 6 through 8. An exploratory factor analysis identified two factors among alcohol-specific communication items, permissive messages and negative alcohol messages. Results showed previous level of adolescent alcohol use moderated the relation between permissive messages and alcohol use outcomes. Plotting of these interactions showed greater alcohol use and consequences with increasing permissive messages in adolescents with higher versus lower levels of previous alcohol use. Results suggest that parental messages regarding alcohol use may impact adolescent alcohol use beyond the effect of general parenting style and parental alcohol use.

This study examined rates of specific anxiety diagnoses (posttraumatic stress disorder, generalized anxiety disorder, panic disorder, obsessive-compulsive disorder, social anxiety disorder, and specific phobia) and anxiety disorder not otherwise specified (anxiety NOS) in a national sample of Veterans and assessed their mental health service utilization. This study used administrative data extracted from Veteran Health Administration outpatient records to identify patients with a new anxiety diagnosis in fiscal year 2010 (N = 292,244). Logistic regression analyses examined associations among diagnostic specificity, diagnostic location, and mental health service utilization. Anxiety NOS was diagnosed in 38% of the sample. Patients in specialty mental health were less likely to receive an anxiety NOS diagnosis than patients in primary care (odds ratio [OR] = 0.36). Patients with a specific anxiety diagnosis were more likely to receive mental health services than those with anxiety NOS (OR = 1.65), as were patients diagnosed in specialty mental health compared with those diagnosed in primary care (OR = 16.29). Veterans diagnosed with anxiety NOS are less likely to access mental health services than those with a specific anxiety diagnosis, suggesting the need for enhanced diagnostic and referral practices, particularly in primary care settings.

In clinical practice, the diagnosis of cervical radiculopathy is based on information from the patient's history, physical examination, and diagnostic imaging. Various physical tests may be performed, but their diagnostic accuracy is unknown. This study aimed to summarize and update the evidence on diagnostic performance of tests carried out during a physical examination for the diagnosis of cervical radiculopathy. A review of the accuracy of diagnostic tests was carried out. The study sample comprised diagnostic studies comparing results of tests performed during a physical examination in diagnosing cervical radiculopathy with a reference standard of imaging or surgical findings. Sensitivity, specificity, likelihood ratios are presented, together with pooled results for sensitivity and specificity. A literature search up to March 2016 was performed in CENTRAL, PubMed (MEDLINE), Embase, CINAHL, Web of Science, and Google Scholar. The methodological quality of studies was assessed using the QUADAS-2. Five diagnostic accuracy studies were identified. Only Spurling's test was evaluated in more than one study, showing high specificity ranging from 0.89 to 1.00 (95% confidence interval [CI]: 0.59-1.00); sensitivity varied from 0.38 to 0.97 (95% CI: 0.21-0.99). No studies were found that assessed the diagnostic accuracy of widely used neurological tests such as key muscle strength, tendon reflexes, and sensory impairments. There is limited evidence for accuracy of physical examination tests for the diagnosis of cervical radiculopathy. When consistent with patient history, clinicians may use a combination of Spurling's, axial traction, and an Arm Squeeze test to increase the likelihood of a cervical radiculopathy, whereas a combined results of four negative neurodynamics tests and an Arm Squeeze test could be used to rule out the disorder.

Stop identity cue as a cue to language identity
NASA Astrophysics Data System (ADS)
Castonguay, Paula Lisa
The purpose of the present study was to determine whether language membership could potentially be cued by the acoustic-phonetic detail of word-initial stops and retained all the way through the process of lexical access to aid in language identification. Of particular interest were language-specific differences in CE and CF word-initial stops. Experiment 1 consisted of an interlingual homophone production task. The purpose of this study was to examine how word-initial stop consonants differ in terms of acoustic properties in Canadian English (CE) and Canadian French (CF) interlingual homophones. The analyses from the bilingual speakers in Experiment 1 indicate that bilinguals do produce language-specific differences in CE and CF word-initial stops, and that closure duration, voice onset time, and burst spectral SD may provide cues to language identity in CE and CF stops. Experiment 2 consisted of a Phoneme and Language Categorization task. The purpose of this study was to examine how stop identity cues, such as VOT and closure duration, influence a listener to identify word-initial stop consonants as belonging to Canadian English (CE) or Canadian French (CF). The RTs from the bilingual listeners in this study indicate that bilinguals do perceive language-specific differences in CE and CF word-initial stops, and that voice onset time may provide cues to phoneme and language membership in CE and CF stops. Experiment 3 consisted of a Phonological-Semantic priming task. The purpose of this study was to examine how subphonetic variations, such as changes in the VOT, affect lexical access. The results of Experiment 3 suggest that language-specific cues, such as VOT, affects the composition of the bilingual cohort and that the extent to which English and/or French words are activated is dependent on the language-specific cues present in a word. The findings of this study enhanced our theoretical understanding of lexical structure and lexical access in bilingual speakers. In addition, this study provides further insight on cross-language effects at the subphonetic level.

So far, a recognizable pattern of clinical symptoms for child sexual abuse (CSA), especially in young male children, is lacking. To improve early recognition of CSA, we reviewed physical complaints, physical examination, and tests on sexually transmitted infections (STIs) in confirmed victims (predominantly preschool boys) of CSA from the Amsterdam sexual abuse case (ASAC). We retrospectively analyzed the outcomes of the primary assessment using mixed methods: descriptive analysis of physical complaints, physical exams, and STI tests from medical files and a qualitative analysis on expert's interpretations of physical complaints and children's behavior during physical examination. We included 54 confirmed CSA victims, median age 3.2 (0-6) years, 43 boys (80%), and 11 girls (20%). Physical complaints were reported in 50%, of which gastrointestinal and anogenital complaints were most common. None of the children showed CSA-specific genital signs at physical examination. Most prominent finding during physical examination was a deviant behavioral response (anxiety, withdrawal, too outgoing) in 15 children (28%), especially in children who experienced anal/vaginal penetration. Testing for STIs was negative. Physical complaints and physical signs at examinations were non-specific for CSA. Deviant behavioral reactions during physical examination were the most prominent finding. Precise observation of a child's behavior during physical examination is needed. What is known • Child sexual abuse (CSA) affects many children on both the short and the long term but remains unrecognized in most cases. • So far, there is a lack of studies on symptom patterns of CSA in male, preschool children. What is new • None of the children showed CSA-specific findings at physical and anogenital examination; STIs were not found in the confirmed victims of CSA. • The most prominent finding was the deviant behavioral response of the children examined, especially in children who experienced anal/vaginal penetration; therefore, precise observation of a child's behavior during physical examination is a crucial part of the evaluation of suspected CSA.
Sensitivity of physical examination versus arthroscopy in diagnosing subscapularis tendon injury.
Faruqui, Sami; Wijdicks, Coen; Foad, Abdullah
2014-01-01
The purpose of this study was to examine the accuracy of physical examination in the detection of subscapularis tendon tears and compare it with the gold standard of arthroscopy to determine whether clinical examination can reliably predict the presence of subscapularis tendon tears. This was a retrospective analysis of 52 patients (52 shoulders) who underwent arthroscopic subscapularis tendon repairs between September 2008 and April 2012. Positive findings on any combination of the belly press, lift-off, and bear hug tests constituted a positive physical examination result. There was a positive finding on physical examination in 42 of 52 patients. The sensitivity of the physical examination as a whole was 81%. The literature has shown that the belly press, bear hug, and lift-off tests are specific to the subscapularis tendon. To the authors’ knowledge, this is the first study to evaluate the sensitivity of these 3 separate clinical tests as a composite. Knowledge regarding the sensitivity of the subscapularis-specific physical examination as a composite can lead practitioners to implement all 3 components, even when 1 test has a negative finding, thus promoting a more thorough physical examination. Because unrepaired subscapularis tendon tears can result in poor outcomes in the repair of other rotator cuff tendons, a complete physical examination would be beneficial to patients with shoulder pathology. The authors conclude that physical examination, when performed consistently by an experienced practitioner, can reliably predict the presence of subscapularis tendon tears.

Previous studies have examined participation in specific leisure-time physical activities (PA) among US adults. The purpose of this study was to identify specific activities that contribute substantially to total volume of leisure-time PA in US adults. Proportion of total volume of leisure-time PA moderate-equivalent minutes attributable to 9 specific types of activities was estimated using self-reported data from 21,685 adult participants (≥ 18 years) in the National Health and Nutrition Examination Survey 1999-2006. Overall, walking (28%), sports (22%), and dancing (9%) contributed most to PA volume. Attributable proportion was higher among men than women for sports (30% vs. 11%) and higher among women than men for walking (36% vs. 23%), dancing (16% vs. 4%), and conditioning exercises (10% vs. 5%). The proportion was lower for walking, but higher for sports, among active adults than those insufficiently active and increased with age for walking. Compared with other racial/ethnic groups, the proportion was lower for sports among non-Hispanic white men and for dancing among non-Hispanic white women. Walking, sports, and dance account for the most activity time among US adults overall, yet some demographic variations exist. Strategies for PA promotion should be tailored to differences across population subgroups.
Bendectin and birth defects. II: Ecological analyses.
Kutcher, Jeffrey S; Engle, Arnold; Firth, Jacqueline; Lamm, Steven H
2003-02-01
Bendectin was the primary pharmaceutical treatment of nausea and vomiting of pregnancy (NVP) in the United States until the early 1980s. Its manufacture was then discontinued after public allegations that it was causing birth defects. Subsequently, meta-analyses of the many epidemiological cohort and case/control studies used to examine that hypothesis have demonstrated the absence of a detectable teratogenic effect. This study presents an ecological analysis of the same hypothesis that examines specific malformations. Annual birth defect prevalence data for the 1970s to the 1990s have been obtained for specific birth defects from the Center for Disease Control's nationwide Birth Defect Monitoring Program. These data for the US have been compared graphically to the annual US Bendectin sales for the treatment of NVP. Data have also been obtained for annual US rates for hospitalization for NVP. The three data sets have been temporally compared in graphic analysis. The temporal trends in prevalence rates for specific birth defects examined from 1970 through 1992 did not show changes that reflected the cessation of Bendectin use over the 1980-84 period. Further, the NVP hospitalization rate doubled when Bendectin use ceased. The population results of the ecological analyses complement the person-specific results of the epidemiological analyses in finding no evidence of a teratogenic effect from the use of Bendectin.

Introduction: This ground-based investigation accumulated high-level clinical evidence on the sensitivity and specificity of point of care ultrasound performed by expert and novice users for the rapid diagnosis of musculoskeletal (MSK) injuries. We developed preliminary educational methodologies to provide just-in-time training of novice users by creating multi-media training tools and imaging procedures for non expert operators and evaluated the sensitivity and specificity of non-expert performed musculoskeletal ultrasound to diagnose acute injuries in a Level 1 Trauma Center. Methods: Patients with potential MSK injuries were identified in the emergency room. A focused MSK ultrasound was performed by expert operators and compared to standard radiographs. A repeat examination was performed by non-expert operators who received a short, just-in-time multimedia education aid. The sensitivity and specificity of the expert and novice ultrasound examinations were compared to gold standard radiography. Results: Over 800 patients were enrolled in this study. The sensitivity and specificity of expert performed ultrasound exceeded 98% for MSK injuries. Novice operators achieved 97% sensitivity and 99% specificity for targeted examinations with the greatest error in fractures involving the hand and foot. Conclusion: Point of care ultrasound is a sensitive and specific diagnostic test for MSK injury when performed by experts and just-in-time trained novice operators.

Team handball is a complex sport game that is determined by the individual performance of each player as well as tactical components and interaction of the team. The aim of this review was to specify the elements of team-handball performance based on scientific studies and practical experience, and to convey perspectives for practical implication. Scientific studies were identified via data bases of PubMed, Web of Knowledge, SPORT Discus, Google Scholar, and Hercules. A total of 56 articles met the inclusion criteria. In addition, we supplemented the review with 13 additional articles, proceedings and book sections. It was found that the specific characteristics of team-handball with frequent intensity changes, team-handball techniques, hard body confrontations, mental skills and social factors specify the determinants of coordination, endurance, strength and cognition. Although we found comprehensive studies examining individual performance in team-handball players of different experience level, sex or age, there is a lack of studies, particularly for team-handball specific training, as well as cognition and social factors. Key Points The specific characteristics of team-handball with frequent intensity changes, specific skills, hard body confrontations, mental skills and social factors define the determinants of coordination, endurance, strength and cognition. To increase individual and team performance in team-handball specific training based on these determinants have been suggested. Although there are comprehensive studies examining individual performance in team-handball players of different experience level, sex, or age are published, there is a lack of training studies, particularly for team-handball specific techniques and endurance, as well as cognition and social factors.

Purpose: Current methods for estimating and reporting radiation dose from CT examinations are largely patient-generic; the body size and hence dose variation from patient to patient is not reflected. Furthermore, the current protocol designs rely on dose as a surrogate for the risk of cancer incidence, neglecting the strong dependence of risk on age and gender. The purpose of this study was to develop a method for estimating patient-specific radiation dose and cancer risk from CT examinations. Methods: The study included two patients (a 5-week-old female patient and a 12-year-old male patient), who underwent 64-slice CT examinations (LightSpeed VCT, GE Healthcare) of the chest, abdomen, and pelvis at our institution in 2006. For each patient, a nonuniform rational B-spine (NURBS) based full-body computer model was created based on the patient’s clinical CT data. Large organs and structures inside the image volume were individually segmented and modeled. Other organs were created by transforming an existing adult male or female full-body computer model (developed from visible human data) to match the framework defined by the segmented organs, referencing the organ volume and anthropometry data in ICRP Publication 89. A Monte Carlo program previously developed and validated for dose simulation on the LightSpeed VCT scanner was used to estimate patient-specific organ dose, from which effective dose and risks of cancer incidence were derived. Patient-specific organ dose and effective dose were compared with patient-generic CT dose quantities in current clinical use: the volume-weighted CT dose index (CTDIvol) and the effective dose derived from the dose-length product (DLP). Results: The effective dose for the CT examination of the newborn patient (5.7 mSv) was higher but comparable to that for the CT examination of the teenager patient (4.9 mSv) due to the size-based clinical CT protocols at our institution, which employ lower scan techniques for smaller patients. However, the overall risk of cancer incidence attributable to the CT examination was much higher for the newborn (2.4 in 1000) than for the teenager (0.7 in 1000). For the two pediatric-aged patients in our study, CTDIvol underestimated dose to large organs in the scan coverage by 30%–48%. The effective dose derived from DLP using published conversion coefficients differed from that calculated using patient-specific organ dose values by −57% to 13%, when the tissue weighting factors of ICRP 60 were used, and by −63% to 28%, when the tissue weighting factors of ICRP 103 were used. Conclusions: It is possible to estimate patient-specific radiation dose and cancer risk from CT examinations by combining a validated Monte Carlo program with patient-specific anatomical models that are derived from the patients’ clinical CT data and supplemented by transformed models of reference adults. With the construction of a large library of patient-specific computer models encompassing patients of all ages and weight percentiles, dose and risk can be estimated for any patient prior to or after a CT examination. Such information may aid in decisions for image utilization and can further guide the design and optimization of CT technologies and scan protocols. PMID:21361209

Recent smoking cessation studies have shown that decreasing experiential avoidance (EA) (i.e., tendency to reduce or avoid internal distress) improves success, but to date none have examined the moderating effect of EA on the role of specific internal distress in smoking cessation. This study examined whether pre-quit general EA (Acceptance & Action Questionnaire) and smoking-specific EA (Avoidance and Inflexibility Scale) moderated the relations between four measures of post-quit internal distress (depressive symptoms, negative affect, physical withdrawal symptoms, craving), and smoking. Participates: 40 adult smokers who participated in a randomized controlled trial of Distress Tolerance treatment for smokers with a history of early lapse. Results: Multilevel models showed that pre-quit smoking-specific EA, but not general EA, significantly moderated the relationship between all measures of internal distress, except craving, and smoking over 13 weeks post-quit. When examined over 26 weeks, these relations remained unchanged for all, but the moderating effect became trend-level for depressive symptoms. Significant associations between post-quit internal distress and smoking were found only in those with high pre-quit smoking-specific EA. Moreover, pre-quit smoking-specific EA did not predict post-quit levels or changes in internal distress, suggesting that decreasing smoking-specific EA pre-quit may not reduce internal distress, but may instead reduce smoking risk in response to such distress during a quit attempt. Conclusions: Results mainly supported hypothesized relations, but only for smoking-specific EA. Smoking cessation interventions focusing on EA reduction may especially benefit those vulnerable to greater post-quit depressive and withdrawal symptoms, and those who smoke to regulate aversive internal states.

A parsimonious characterization of change in global age-specific and total fertility rates
2018-01-01
This study aims to understand trends in global fertility from 1950-2010 though the analysis of age-specific fertility rates. This approach incorporates both the overall level, as when the total fertility rate is modeled, and different patterns of age-specific fertility to examine the relationship between changes in age-specific fertility and fertility decline. Singular value decomposition is used to capture the variation in age-specific fertility curves while reducing the number of dimensions, allowing curves to be described nearly fully with three parameters. Regional patterns and trends over time are evident in parameter values, suggesting this method provides a useful tool for considering fertility decline globally. The second and third parameters were analyzed using model-based clustering to examine patterns of age-specific fertility over time and place; four clusters were obtained. A country’s demographic transition can be traced through time by membership in the different clusters, and regional patterns in the trajectories through time and with fertility decline are identified.

A clinical study of cutaneous changes in pregnancy.
Panicker, Vinitha V; Riyaz, Najeeba; Balachandran, P K

Pregnant women experience a myriad of physiological and metabolic changes that affect different organ systems in the body. Cutaneous and appendageal alterations that manifest during pregnancy are largely modulated by hormonal, immunologic, and metabolic factors. Detailed reports encompassing physiological changes and specific dermatoses of pregnancy and effects of various dermatoses on pregnant women are scanty in literature. This study was conducted to examine in detail both physiological changes and specific dermatoses. The cutaneous changes are divided into physiological changes, skin diseases aggravated by pregnancy, and specific dermatoses of pregnancy. The objectives were to study the various cutaneous changes of pregnancy and to know the proportion of these cutaneous manifestations in pregnant women. This study included 600 pregnant women attending the Obstetrics and Gynecology Department of a tertiary teaching hospital in Northern Kerala, India. Detailed history elicitation and complete physical and dermatological examination were performed. Skin biopsy was performed in relevant cases. Cutaneous changes were seen in a majority of patients, of which physiological changes were the most common (99%). The most common cutaneous manifestation was hyperpigmentation (526; 87.6%), followed by striae gravidarum (72.8%). Other changes were vascular, including pedal edema (10%), pregnancy gingivitis (1.8%), and varicose veins (1%). Infections were the common dermatological problem in this study group. The most common infections were vulvovaginal candidiasis (21%), Tinea versicolor (6%), scabies (2.8%), dermatophytosis (1.5%), and sexually transmitted infection (0.5%). Specific dermatoses were seen in 12 cases (2%), with the most common being pruritic urticarial papules and plaques of pregnancy (1.3%). Pregnant women are prone to suffer from a wide range of dermatological problems apart from specific dermatoses of pregnancy. The study emphasizes the need for a detailed and meticulous examination of these patients to detect these various disorders. Copyright © 2016 Ministry of Health, Saudi Arabia.

Reducing lumbar spine MRI scanning time while retaining diagnostic accuracy can benefit patients and reduce health care costs. This study compares the effectiveness of a rapid lumbar MRI protocol using 3D T2-weighted sampling perfection with application-optimized contrast with different flip-angle evolutions (SPACE) sequences with a standard MRI protocol for evaluation of lumbar spondylosis. Two hundred fifty consecutive unenhanced lumbar MRI examinations performed at 1.5 T were retrospectively reviewed. Full, rapid, and complete versions of each examination were interpreted for spondylotic changes at each lumbar level, including herniations and neural compromise. The full examination consisted of sagittal T1-weighted, T2-weighted turbo spin-echo (TSE), and STIR sequences; and axial T1- and T2-weighted TSE sequences (time, 18 minutes 40 seconds). The rapid examination consisted of sagittal T1- and T2-weighted SPACE sequences, with axial SPACE reformations (time, 8 minutes 46 seconds). The complete examination consisted of the full examination plus the T2-weighted SPACE sequence. Sensitivities and specificities of the full and rapid examinations were calculated using the complete study as the reference standard. The rapid and full studies had sensitivities of 76.0% and 69.3%, with specificities of 97.2% and 97.9%, respectively, for all degenerative processes. Rapid and full sensitivities were 68.7% and 66.3% for disk herniation, 85.2% and 81.5% for canal compromise, 82.9% and 69.1% for lateral recess compromise, and 76.9% and 69.7% for foraminal compromise, respectively. Isotropic SPACE T2-weighted imaging provides high-quality imaging of lumbar spondylosis, with multiplanar reformatting capability. Our SPACE-based rapid protocol had sensitivities and specificities for herniations and neural compromise comparable to those of the protocol without SPACE. This protocol fits within a 15-minute slot, potentially reducing costs and discomfort for a large subgroup of patients.

In pediatric care, the role of focused abdominal sonography in trauma (FAST) remains ill defined. The objective of this study was to assess the sensitivity and specificity of FAST for detecting free peritoneal fluid in children. The trauma registry of a single level I pediatric trauma center was queried for the results of FAST examination of consecutive pediatric (<18 years) blunt trauma patients over a period of 36 months, from January 2010 to December 2012. Demographics, type of injuries, FAST results, computerized tomography (CT) results, and operative findings were reviewed. During the study period, 543 injured pediatric patients (mean age 8.2 ± 5 years) underwent FAST examinations. In 95 (17.5 %) FAST was positive for free peritoneal fluid. CT examination was performed in 219 (40.3 %) children. Positive FAST examination was confirmed by CT scan in 61/73 (83.6 %). CT detected intra-peritoneal fluid in 62/448 (13.8 %) of the patients with negative FAST results. These findings correspond to a sensitivity of 50 %, specificity of 88 %, positive predictive value (PPV) of 84 %, and a negative predictive value (NPV) of 58 %. In patients who had negative FAST results and no CT examination (302), no missed abdominal injury was detected on clinical ground. FAST examination in the young age group (<2 years) yielded lower sensitivity and specificity (36 and 78 % respectively) with a PPV of only 50 %. This study shows that although a positive FAST evaluation does not necessarily correlate with an IAI, a negative one strongly suggests the absence of an IAI, with a high NPV. These findings are emphasized in the analysis of the subgroup of children less than 2 years of age. FAST examination tempered with sound clinical judgment seems to be an effective tool to discriminate injured children in need of further imaging evaluation.

Leadership practices of health care managers can positively or negatively influence outcomes for organizations, providers and, ultimately, patients. Understanding the factors that contribute to nursing leadership is fundamental to ensuring a future supply of nursing leaders who can positively influence outcomes for health care providers and patients. The purpose of this study was to systematically review the multidisciplinary literature to examine the factors that contribute to nursing leadership and the effectiveness of educational interventions in developing leadership behaviours among nurses. The search strategy began with 10 electronic databases (e.g. CINAHL, Medline). Published quantitative studies were included that examined the factors that contribute to leadership or the development of leadership behaviours in nurse leaders. Quality assessments, data extraction and analysis were completed on all included studies. A total of 27,717 titles/abstracts were screened resulting in 26 included manuscripts reporting on 24 studies. Twenty leadership factors were examined and categorized into four groups - behaviours and practices of individual leaders, traits and characteristics of individual leaders, influences of context and practice settings, and leader participation in educational activities. Specific behaviours and practices of individual leaders, such as taking on or practising leadership styles, skills and roles, were reported as significantly influencing leadership in eight studies. Traits and characteristics of individual leaders were examined in six studies with previous leadership experience (three studies) and education levels (two of three studies) having positive effects on observed leadership. Context and practice settings had a moderate influence on leadership effectiveness (three of five studies). Nine studies that examined participation in leadership development programs all reported significant positive influences on observed leadership. These findings suggest that leadership can be developed through specific educational activities, and by modelling and practising leadership competencies. However, the relatively weak study designs provide limited evidence for specific factors that could increase the effectiveness of current nursing leadership or guide the identification of future nurse leaders. Robust theory and research on interventions to develop and promote viable nursing leadership for the future are needed to achieve the goal of developing healthy work environments for health care providers and optimizing care for patients.

Individuals with chronic conditions can benefit from formulating action plans to engage in regular physical activity. However, the content and the successful translation of plans into action, so-called plan enactment, are rarely adequately evaluated. The aim of this study was to describe the content of user-specified plans and to examine whether participants were more likely to enact their plans if these plans were highly specific, viable, and instrumental. The study presents secondary analyses from a larger behavioural intervention in cardiac and orthopaedic rehabilitation. The content of 619 action plans from 229 participants was evaluated by two independent raters (i.e., qualitative analyses and ratings of specificity) and by participants themselves (i.e., instrumentality and viability). Plan enactment was also measured via self-reports. Multilevel analyses examined the relationship between these plan characteristics and subsequent plan enactment, and between plan enactment and aggregated physical activity. Participants preferred to plan leisure-time physical activities anchored around time-based cues. Specificity of occasion cues (i.e., when to act) and highly instrumental plans were positively associated with plan enactment. Interestingly, individuals who planned less specific behavioural responses (i.e., what to do) were more likely to enact their plans. Plan enactment was positively associated with aggregated behaviour. Interventions should not only emphasize the importance of planning, but also the benefits of formulating specific contextual cues. Planning of the behavioural response seems to require less precision. Allowing for some flexibility in executing the anticipated target behaviour seems to aid successful plan enactment. Statement of Contribution What is already known on this subject? Action planning interventions are efficacious in promoting health behaviour. Characteristics of plan content (i.e., specificity) matter for unconditional behaviour change. Plan enactment (i.e., degree to which plan is followed through) is positively linked to behaviour change. What does this study add? Specificity of occasion cues (i.e., when to act) and highly instrumental plans were positively associated with plan enactment. Individuals who planned less specific behavioural responses (i.e., what to do) were more likely to enact their plans. Planning interventions should focus on specificity of context cues but flexibility of behavioural action. © 2017 The British Psychological Society.

The current study explores the problem with the lack of measurement invariance for the Narcissistic Personality Inventory (NPI) by addressing two issues: conceptual heterogeneity of narcissism and methodological issues related to the binary character of data. We examine the measurement invariance of the 13-item version of the NPI in three populations in Japan, Poland and the UK. Analyses revealed that leadership/authority and grandiose exhibitionism dimensions of the NPI were cross-culturally invariant, while entitlement/exploitativeness was culturally specific. Therefore, we proposed NPI-9 as indicating scalar invariance, and we examined the pattern of correlations between NPI-9 and other variables across three countries. The results suggest that NPI-9 is valid brief scale measuring general levels of narcissism in cross-cultural studies, while the NPI-13 remains suitable for research within specific countries. © 2018 International Union of Psychological Science.

Low-back pain with leg pain (sciatica) may be caused by a herniated intervertebral disc exerting pressure on the nerve root. Most patients will respond to conservative treatment, but in carefully selected patients, surgical discectomy may provide faster relief of symptoms. Primary care clinicians use patient history and physical examination to evaluate the likelihood of disc herniation and select patients for further imaging and possible surgery. (1) To assess the performance of tests performed during physical examination (alone or in combination) to identify radiculopathy due to lower lumbar disc herniation in patients with low-back pain and sciatica;(2) To assess the influence of sources of heterogeneity on diagnostic performance. We searched electronic databases for primary studies: PubMed (includes MEDLINE), EMBASE, and CINAHL, and (systematic) reviews: PubMed and Medion (all from earliest until 30 April 2008), and checked references of retrieved articles. We considered studies if they compared the results of tests performed during physical examination on patients with back pain with those of diagnostic imaging (MRI, CT, myelography) or findings at surgery. Two review authors assessed the quality of each publication with the QUADAS tool, and extracted details on patient and study design characteristics, index tests and reference standard, and the diagnostic two-by-two table. We presented information on sensitivities and specificities with 95% confidence intervals (95% CI) for all aspects of physical examination. Pooled estimates of sensitivity and specificity were computed for subsets of studies showing sufficient clinical and statistical homogeneity. We included 16 cohort studies (median N = 126, range 71 to 2504) and three case control studies (38 to100 cases). Only one study was carried out in a primary care population. When used in isolation, diagnostic performance of most physical tests (scoliosis, paresis or muscle weakness, muscle wasting, impaired reflexes, sensory deficits) was poor. Some tests (forward flexion, hyper-extension test, and slump test) performed slightly better, but the number of studies was small. In the one primary care study, most tests showed higher specificity and lower sensitivity compared to other settings.Most studies assessed the Straight Leg Raising (SLR) test. In surgical populations, characterized by a high prevalence of disc herniation (58% to 98%), the SLR showed high sensitivity (pooled estimate 0.92, 95% CI: 0.87 to 0.95) with widely varying specificity (0.10 to 1.00, pooled estimate 0.28, 95% CI: 0.18 to 0.40). Results of studies using imaging showed more heterogeneity and poorer sensitivity. The crossed SLR showed high specificity (pooled estimate 0.90, 95% CI: 0.85 to 0.94) with consistently low sensitivity (pooled estimate 0.28, 95% CI: 0.22 to 0.35).Combining positive test results increased the specificity of physical tests, but few studies presented data on test combinations. When used in isolation, current evidence indicates poor diagnostic performance of most physical tests used to identify lumbar disc herniation. However, most findings arise from surgical populations and may not apply to primary care or non-selected populations. Better performance may be obtained when tests are combined.

Undernourished patients discharged from the hospital require follow-up; however, attendance at return visits is low. Teleconsultations may allow remote follow-up of undernourished patients; however, no valid method to remotely perform physical examination, a critical component of assessing nutritional status, exists. This study aims to compare agreement between photographs taken by trained dietitians and in-person physical examinations conducted by trained dietitians to rate the overall physical examination section of the scored Patient Generated Subjective Global Assessment (PG-SGA). Nested cross-sectional study. Adults aged ≥60 years, admitted to the general medicine unit at Flinders Medical Centre between March 2015 and March 2016, were eligible. All components of the PG-SGA and photographs of muscle and fat sites were collected from 192 participants either in the hospital or at their place of residence after discharge. Validity of photograph-based physical examination was determined by collecting photographic and PG-SGA data from each participant at one encounter by trained dietitians. A dietitian blinded to data collection later assessed de-identified photographs on a computer. Percentage agreement, weighted kappa agreement, sensitivity, and specificity between the photographs and in-person physical examinations were calculated. All data collected were included in the analysis. Overall, the photograph-based physical examination rating achieved a percentage agreement of 75.8% against the in-person assessment, with a weighted kappa agreement of 0.526 (95% CI: 0.416, 0.637; P<0.05) and a sensitivity-specificity pair of 66.9% (95% CI: 57.8%, 75.0%) and 92.4% (95% CI: 82.5%, 97.2%). Photograph-based physical examination by trained dietitians achieved a nearly acceptable percentage agreement, moderate weighted kappa, and fair sensitivity-specificity pair. Methodological refinement before field testing with other personnel may improve the agreement and accuracy of photograph-based physical examination.

We present findings from a study that focused on specific executive functions (EF) in children with and without specific language impairment (SLI). We analyzed performance patterns and EF profiles (spatial working memory, inhibition control, and sustained attention) in school-age SLI children and two control groups: age-matched and language matched. Our main research goal was to identify those EFs that show a weakness in children with SLI. Our specific aims were to: (1) examine whether the EF problems in children with SLI are domain-general; (2) examine whether deficits in EF in children with SLI can be explained by the general slowness hypothesis or by an overall delay in development; (3) compare EF profiles to examine whether children with SLI show a distinct pattern of performance from their peers. Our findings showed different EF profiles for the groups. We observed differences in performance patterns related to age (e.g., reaction time in response inhibition) and differences related to language status (e.g., sensitivity to interference). The findings show interesting associations in EFs that play a crucial role in language processing. PMID:25302062

The present study examines gender differences in the mechanisms that explain the association between PTSD symptoms and substance use frequency in a sample of 182 urban substance users. Specifically, the current study examined gender differences in the role of two potential explanatory variables, namely, difficulties controlling impulsive behavior when distressed (IMP), and a lack of emotional awareness and clarity (AW/CLAR). Multiple-group path modeling (across males and females) was used to examine gender differences in the path coefficients from PTSD symptoms to IMP and AW/CLAR, and from these latter variables to drug use frequency. Results indicated that PTSD symptoms were associated with IMP and AW/CLAR, and these path coefficients did not vary by gender. However, gender differences emerged when considering the path coefficients from AW/CLAR and IMP to substance use frequency. Specifically, for women, the association between PTSD and substance use was partially explained by IMP, whereas for men, the association between PTSD and substance use was partially explained by AW/CLAR. The current study is the first to examine gender differences in mechanisms accounting for the association between PTSD and substance use frequency, and these results also support the value and importance of examining gender differences in mechanisms underlying PTSD-SUD comorbidity.

With an increasing focus on biomarkers in dementia research, illustrating the role of neuropsychological assessment in detecting mild cognitive impairment (MCI) and Alzheimer's dementia (AD) is important. This systematic review and meta-analysis, conducted in accordance with PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) standards, summarizes the sensitivity and specificity of memory measures in individuals with MCI and AD. Both meta-analytic and qualitative examination of AD versus healthy control (HC) studies (n = 47) revealed generally high sensitivity and specificity (≥ 80% for AD comparisons) for measures of immediate (sensitivity = 87%, specificity = 88%) and delayed memory (sensitivity = 89%, specificity = 89%), especially those involving word-list recall. Examination of MCI versus HC studies (n = 38) revealed generally lower diagnostic accuracy for both immediate (sensitivity = 72%, specificity = 81%) and delayed memory (sensitivity = 75%, specificity = 81%). Measures that differentiated AD from other conditions (n = 10 studies) yielded mixed results, with generally high sensitivity in the context of low or variable specificity. Results confirm that memory measures have high diagnostic accuracy for identification of AD, are promising but require further refinement for identification of MCI, and provide support for ongoing investigation of neuropsychological assessment as a cognitive biomarker of preclinical AD. Emphasizing diagnostic test accuracy statistics over null hypothesis testing in future studies will promote the ongoing use of neuropsychological tests as Alzheimer's disease research and clinical criteria increasingly rely upon cerebrospinal fluid (CSF) and neuroimaging biomarkers.

No studies have specifically investigated how hospice patients view the prospect of physical examination by students. Previous evidence involves patients who have already seen students, while the views of other patients are unknown. This study aimed to provide an initial understanding of the views of a diverse group of hospice inpatients on the acceptability and perceived importance of students physically examining them. 42 hospice inpatients completed a short questionnaire focusing on their views of medical students examining them. Patients chose to do this alone or via a short interview. All inpatients at Exeter Hospice were considered eligible, including patients who were asked and those who may not have been asked to see students; all 42 patients completed the study. In accordance with existing evidence, patients generally held positive views about seeing students. However, many patients expressed concerns about being physically examined by students, specifically including that it might be painful, tiring or embarrassing. Most importantly, several patients who did not wish to be examined by medical students said they would feel obliged to accept it, or would find it difficult to decline. Hospice inpatients generally wish to be involved in medical student teaching, but many are concerned about being physically examined, and some feel a sense of obligation to participate. There are implications for hospices that teach students. Further research is necessary to investigate the frequency and severity of these concerns.

Objective Many persons with knee pain have joint pain outside the knee but despite the impact and high frequency of this pain, its distribution and causes have not been studied. Those studying gait abnormalities have suggested that knee pain causes pain in adjacent joints but pain adaptation strategies are highly individualized. Methods We studied persons age 50-79 years with or at high risk of knee osteoarthritis drawn from two community-based cohorts, the Multicenter Osteoarthritis Study and the Osteoarthritis Initiative and followed for 5-7 years. We excluded those with knee pain at baseline and compared those who developed and did not develop knee pain at the first follow-up examination (the index visit). We examined pain on most days at joint regions outside the knee in examinations after the index visit. Logistic regression analyses examined the risk of joint specific pain adjusted for age, sex, BMI, depression with sensitivity analyses excluding those with widespread pain. Results In the combined cohorts, there were 693 persons with index visit knee pain vs. 2793 without it. 79.6% of those with bilateral and 63.8% of those with unilateral knee pain had pain during follow-up in a joint region outside the knee vs. 49.9% of those without knee pain. An increased risk of pain was present in most extremity joint sites without a predilection for specific sites. Results were unchanged when those with widespread pain were excluded. Conclusions Persons with chronic knee pain are at increased risk of pain in multiple joints in no specific pattern. PMID:27589036

Evaluating patients for recurrent anal cancer after primary treatment can be difficult owing to distorted anatomy and scarring. Many institutions incorporate endoscopic ultrasound to improve detection, but the effectiveness is unknown. The aim of this study is to compare the effectiveness of digital rectal examination and endoscopic ultrasound in detecting locally recurrent disease during routine follow-up of patients with anal cancer. This study is a retrospective, single-institution review. This study was conducted at an oncologic tertiary referral center. Included were 175 patients with nonmetastatic anal squamous-cell cancer, without persistent disease after primary chemoradiotherapy, who had at least 1 posttreatment ultrasound and examination by a colorectal surgeon. The primary outcomes measured were the first modality to detect local recurrence, concordance, crude cancer detection rate, sensitivity, specificity, and predictive value. Eight hundred fifty-five endoscopic ultrasounds and 873 digital rectal examinations were performed during 35 months median follow-up. Overall, ultrasound detected 7 (0.8%) mesorectal and 32 (3.7%) anal canal abnormalities; digital examination detected 69 (7.9%) anal canal abnormalities. Locally recurrent disease was found on biopsy in 8 patients, all detected first or only with digital examination. Four patients did not have an ultrasound at the time of diagnosis of recurrence. The concordance of ultrasound and digital examination in detecting recurrent disease was fair at 0.37 (SE, 0.08; 95% CI, 0.21-0.54), and there was no difference in crude cancer detection rate, sensitivity, specificity, and negative or positive predictive values. The heterogeneity of follow-up timing and examinations is not standardized in this study but is reflective of general practice. Endoscopic ultrasound did not provide any advantage over digital rectal examination in identifying locally recurrent anal cancer, and should not be recommended for routine surveillance.
Bias in the physical examination of patients with lumbar radiculopathy
2010-01-01
Background No prior studies have examined systematic bias in the musculoskeletal physical examination. The objective of this study was to assess the effects of bias due to prior knowledge of lumbar spine magnetic resonance imaging findings (MRI) on perceived diagnostic accuracy of the physical examination for lumbar radiculopathy. Methods This was a cross-sectional comparison of the performance characteristics of the physical examination with blinding to MRI results (the 'independent group') with performance in the situation where the physical examination was not blinded to MRI results (the 'non-independent group'). The reference standard was the final diagnostic impression of nerve root impingement by the examining physician. Subjects were recruited from a hospital-based outpatient specialty spine clinic. All adults age 18 and older presenting with lower extremity radiating pain of duration ≤ 12 weeks were evaluated for participation. 154 consecutively recruited subjects with lumbar disk herniation confirmed by lumbar spine MRI were included in this study. Sensitivities and specificities with 95% confidence intervals were calculated in the independent and non-independent groups for the four components of the radiculopathy examination: 1) provocative testing, 2) motor strength testing, 3) pinprick sensory testing, and 4) deep tendon reflex testing. Results The perceived sensitivity of sensory testing was higher with prior knowledge of MRI results (20% vs. 36%; p = 0.05). Sensitivities and specificities for exam components otherwise showed no statistically significant differences between groups. Conclusions Prior knowledge of lumbar MRI results may introduce bias into the pinprick sensory testing component of the physical examination for lumbar radiculopathy. No statistically significant effect of bias was seen for other components of the physical examination. The effect of bias due to prior knowledge of lumbar MRI results should be considered when an isolated sensory deficit on examination is used in medical decision-making. Further studies of bias should include surgical clinic populations and other common diagnoses including shoulder, knee and hip pathology. PMID:21118558

Background Although specific phobia is characterized by an early age at onset and by high rates of comorbidity, few studies have examined comorbid relationships prospectively. Objectives The present study investigated the association between specific phobia and the risk of a broad range of psychopathology among young women in the community. Method Data came from the Dresden Predictor Study in which 1,538 German women (18–25 years) completed a diagnostic interview at two time points. Results Women with specific phobia had a twofold increase in odds of developing any anxiety disorder, generalized anxiety disorder, depression, and any somatoform disorder during 17 months, compared to women without specific phobia. Except for depression, these associations persisted after adjustment for all comorbid mental disorders. Conclusions Specific phobia thus appears to be a risk factor for a variety of problems. The result further underpins the necessity for early intervention for specific phobia to prevent later mental health problems. PMID:19888542

The World Health Organization Surgical Safety Checklist (SSC) has been widely implemented in an effort to decrease surgical adverse events. This systematic literature review examined the effects of the SSC on postoperative outcomes. The review included 25 studies: two randomised controlled trials, 13 prospective and ten retrospective cohort trials. A meta-analysis was not conducted as combining observational studies of heterogeneous quality may be highly biased. The quality of the studies was largely suboptimal; only four studies had a concurrent control group, many studies were underpowered to examine specific postoperative outcomes and teamwork-training initiatives were often combined with the implementation of the checklist, confounding the results. The effects of the checklist were largely inconsistent. Postoperative complications were examined in 20 studies; complication rates significantly decreased in ten and increased in one. Eighteen studies examined postoperative mortality. Rates significantly decreased in four and increased in one. Postoperative mortality rates were not significantly decreased in any studies in developed nations, whereas they were significantly decreased in 75 % of studies conducted in developing nations. The checklist may be associated with a decrease in surgical adverse events and this effect seems to be greater in developing nations. With the observed incongruence between specific postoperative outcomes and the overall poor study designs, it is possible that many of the positive changes associated with the use of the checklist were due to temporal changes, confounding factors and publication bias.

Study Design Cross-sectional study with prospective recruitment. Objective To determine the accuracy of the physical examination for the diagnosis of midlumbar nerve root impingement (L2, L3, or L4), low lumbar nerve root impingement (L5 or S1) and level-specific lumbar nerve root impingement on magnetic resonance imaging (MRI), using individual tests and combinations of tests. Summary of Background Data The sensitivity and specificity of the physical examination for the localization of nerve root impingement has not been previously studied. Methods Sensitivities, specificities and LRs were calculated for the ability of individual tests and test combinations to predict the presence or absence of nerve root impingement at midlumbar, low lumbar, and specific nerve root levels. Results LRs ≥5.0 indicate moderate to large changes from pre-test probability of nerve root impingement to post-test probability. For the diagnosis of midlumbar impingement, the femoral stretch test (FST), crossed femoral stretch test (CFST), medial ankle pinprick sensation, and patellar reflex testing demonstrated LRs ≥5.0 (LR ∞). LRs ≥5.0 were seen with the combinations of FST and either patellar reflex testing (LR 7.0; 95% CI 2.3–21), or the sit-to-stand test (LR ∞). For the diagnosis of low lumbar impingement, the Achilles reflex test demonstrated a LR ≥5.0 (LR 7.1; CI 0.96–53); test combinations did not increase LRs. For the diagnosis of level-specific impingement, LRs ≥5.0 were seen for anterior thigh sensation at L2 (LR 13; 95% CI 1.8–87); FST at L3 (LR 5.7 ; 95% CI 2.3–4.4); patellar reflex testing (LR 7.7; 95% CI 1.7–35), medial ankle sensation (LR ∞), or CFST (LR 13; 95% CI 1.8–87) at L4; and hip abductor strength at L5(LR 11; 95% CI 1.3–84). Test combinations increased LRs for level-specific root impingement at the L4 level only. Conclusions Individual physical examination tests may provide clinical information which substantially alters the likelihood that midlumbar impingement, low lumbar impingement, or level-specific impingement is present. Test combinations improve diagnostic accuracy for midlumbar impingement. PMID:20543768
Structural basis of substrate specificity in the serine proteases.
Perona, J. J.; Craik, C. S.
1995-01-01
Structure-based mutational analysis of serine protease specificity has produced a large database of information useful in addressing biological function and in establishing a basis for targeted design efforts. Critical issues examined include the function of water molecules in providing strength and specificity of binding, the extent to which binding subsites are interdependent, and the roles of polypeptide chain flexibility and distal structural elements in contributing to specificity profiles. The studies also provide a foundation for exploring why specificity modification can be either straightforward or complex, depending on the particular system. PMID:7795518
Evaluation of sensitivity and specificity of cytologic examination: 269 cases (1999-2000).

To determine sensitivity and specificity of cytologic examination used in a clinical setting. Retrospective study. 216 dogs, 44 cats, 4 horses, 2 ferrets, 1 llama, 1 rat, and 1 mouse. Records were reviewed of cases in which a cytologic diagnosis was followed by a surgical biopsy or postmortem examination within 3 days with subsequent histopathologic diagnosis. Diagnoses were compared for agreement at various levels, including complete agreement, partial agreement, no agreement, or no comparison possible because of insufficient or incorrect cytologic specimen. Levels of agreement were compared for different categories of lesions, including neoplastic, inflammatory, dysplastic-hyperplastic-other, and normal tissue. Additionally, levels of agreement for neoplastic lesions were categorized with regard to cell type, degree of malignancy, and location. Sensitivity and specificity of cytologic examination were calculated. At the level of general agreement (complete and partial agreement), the sensitivity of cytologic examination ranged from 33.3 to 66.1%, depending on the location of the lesion. Cytologic examination was most accurate when used to diagnose cutaneous and subcutaneous lesions and least accurate for diagnosis of liver lesions. Cytologic examination was most effective in diagnosis of neoplastic disease and least effective in diagnosis of dysplastic or hyperplastic conditions. Cytologic examination is a valuable diagnostic tool, although our results indicated lower accuracy than previously reported. False-negative results (missing a diagnosis) were far more common than false-positive results (categorizing a healthy animal as diseased): therefore, if the clinical index of suspicion is high, cytologic examination should be repeated or another technique should be selected to rule out the suspected condition.

Many studies focus on the differences in mental health between lesbian, gay, bisexual (LGB), and heterosexual individuals. Less attention has been paid to the differences in various aspects of sexual health and the potential explanations for these differences. Data from a Dutch population study on sexual health (aged 19-70 years; N = 4,333) were used to examine the potential differences in sexual satisfaction, sexual victimization, sexual dysfunction, and sexual health care need. At the same time, this study examined whether the differences could be attributed to differences in general factors influencing sexual health (sociodemographic variables and sexual behavior characteristics) or to LGB-specific factors (minority stress). The results showed that bisexual women and bi- and homosexual men had more often experienced sexual coercion and reported a higher need for sexual health care than their heterosexual counterparts. Both general determinants (e.g., a higher number of sexual partners or being single) and LGB-specific factors (e.g., internalized homonegativity or negative social reactions related to sexual orientation) were associated with different aspects of sexual health. Interventions aimed at improving the sexual health of LGB individuals should focus on general risk factors, as well as on LGB-specific stressors. Methodological limitations of the study and implications for further research are discussed.
Eating disorder-specific health-related quality of life and exercise in college females.
Cook, Brian J; Hausenblas, Heather A
2011-11-01
Although eating disorder (ED) symptoms result in reduced quality of life (QOL), research is needed to examine variables that influence this relationship. The purpose of our study was to conceptually examine the relationship among ED-specific QOL, ED symptoms, and exercise behavior. Female university students (N = 387) completed ED-specific QOL, exercise behavior, ED symptoms, and exercise dependence symptoms measures. We found support for the beneficial association of psychological QOL on ED symptoms as well as the detrimental association of exercise dependence on ED symptoms. Our results suggest that improvements in psychological aspects of QOL resulting from exercise may mediate ED symptoms when exercise motivations are not pathological. We discuss further research and intervention implications of our findings.

There is considerable interest in examining how Medicaid payment affects nursing home care. This study examines the effect of Medicaid payment methods and reimbursement rates on the delivery of rehabilitation therapy to Medicaid nursing home residents in six States from 1992-1995. In States that changed payment from prospective facility-specific to prospective case-mix adjusted payment methods, Medicaid residents received more rehabilitation therapy after the change. While residents in States using case-mix adjusted payment rates for Medicaid payment were more likely to receive rehabilitation than residents in States using prospective facility-specific Medicaid payment, the differences were general and not specific to Medicaid residents. Retrospective payment for Medicaid resident care was associated with greater use of therapy for Medicaid residents. PMID:17645160

Emotional and cognitive characteristics have been studied in the context of women's cancer screening but have received scant attention in the study of men's screening behavior. Researchers know little about how such factors interact to predict screening or whether digital rectal examination (DRE) and prostate specific antigen (PSA) screens are predicted by the same characteristics. This study examines the relevance of emotional and cognitive characteristics to DRE and PSA screening among 180 U.S.-born African American, U.S.- born European American, and immigrant Jamaican men. The study identifies the expected effects in which fear is negatively related and efficacy beliefs positively related to DRE and PSA screening. Greater efficacy and (marginally) knowledge appear to "offset" the negative impact of fear on screening, and fear appears particularly relevant to DRE frequency. Results are discussed in terms of their implications for the development of health belief and self-regulatory models in the context of prostate cancer screening among minority men.

Objectives To ascertain the sensitivity, specificity, accuracy and concordance of the physical examination (PE) and magnetic resonance imaging (MRI) in comparison with arthroscopy, in diagnosing knee injuries. Methods Prospective study on 72 patients, with evaluation and comparison of PE, MRI and arthroscopic findings, to determine the concordance, accuracy, sensitivity and specificity. Results PE showed sensitivity of 75.00%, specificity of 62.50% and accuracy of 69.44% for medial meniscal (MM) lesions, while it showed sensitivity of 47.82%, specificity of 93.87% and accuracy of 79.16% for lateral meniscal (LM) lesions. For anterior cruciate ligament (ACL) injuries, PE showed sensitivity of 88.67%, specificity of 94.73% and accuracy of 90.27%. For MM lesions, MRI showed sensitivity of 92.50%, specificity of 62.50% and accuracy of 69.44%, while for LM injuries, it showed sensitivity of 65.00%, specificity of 88.46% and accuracy of 81.94%. For ACL injuries, MRI showed sensitivity of 86.79%, specificity of 73.68% and accuracy of 83.33%. For ACL injuries, the best concordance was with PE, while for MM and LM lesions, it was with MRI (p < 0.001). Conclusions Meniscal and ligament injuries can be diagnosed through careful physical examination, while requests for MRI are reserved for complex or doubtful cases. PE and MRI used together have high sensitivity for ACL and MM lesions, while for LM lesions the specificity is higher.

Exposure to violence in the family-of-origin has consistently been linked to intimate partner violence (IPV) perpetration in adulthood. However, whether the transmission of violence across generations is role- and gender-specific still remains unclear. The current study examined the effects of experiencing child abuse and observing parental violence on IPV perpetration among a sample of male arrestees (N = 303). The differential effects of observing violence perpetrated by same-sex (father to mother), opposite-sex (mother to father), and both parents on subsequent IPV perpetration were examined. Logistic regression analyses showed that while observing father-only violence and bidirectional interparental violence was predictive of IPV perpetration, observing mother-only violence and direct experiences of child abuse was not. These findings suggest that the transmission of violence across generations is both role- and gender-specific and highlight the importance of examining unique dimensions of partner violence to assess influences on children. The study further examined whether attitudes justifying wife beating mediate the effect of exposure to violence and subsequent IPV perpetration. Results showed that although attitudes were predictive of perpetration, these attitudes did not mediate the relationship. © The Author(s) 2014.

This study examined the predictive validity of in-clerkship evaluation methods to identify medical students who have insufficient knowledge. Study subjects were 124 third-year medical students at the Uniformed Services University. Insufficient knowledge was defined by: (1) a clerkship 'pre-test' score one standard deviation below the mean or lower; or (2) any teacher verbally rating a student's general knowledge as 'marginal' or less; or (3) a student did not pass Step One of the United States Medical Licensing Examination (USMLE). We determined sensitivity and specificity using a standard score of = 300 on the end of clerkship National Board of Medical Examiners (NBME) subject examination in medicine as the outcome variable. Sixteen students scored = 300 on the NBME examination. The sensitivity of the 'pre-test' or verbal comments alone was 44% (seven of 16 students). By combining methods, 11 students were identified, for a sensitivity of 69%. The specificity of all methods was > 90%. Using USMLE Step One pass-fail performance did not improve sensitivity. Combining a 'pre-test' and instructors' formal evaluation session comments improves the early identification of students with insufficient knowledge, allowing for formative feedback and remediation during the clerkship.

The absence of definitive data or explicit guidelines regarding the use of digital rectal examination for prostate cancer screening may lead to confusion for physicians and patients alike. We evaluated the prognostic value of abnormal digital rectal examination and prostate specific antigen following the widespread dissemination of prostate specific antigen testing in the U.S. Collectively, men comprising the screening arm of the PLCO cancer screening trial who underwent digital rectal examination screening (35,350) were followed for 314,033 person-years. Adjusted analyses with competing risks regression were performed to assess the association of suspicious (nodularity, induration, asymmetry) digital rectal examination and abnormal prostate specific antigen (4 ng/ml or greater) with the detection of clinically significant prostate cancer, prostate cancer specific mortality and overall mortality. Among all screening encounters with a suspicious digital rectal examination only 15.4% had a concurrently abnormal prostate specific antigen (McNemar's test p <0.001). During followup there were 1,612 clinically significant prostate cancers detected, 64 prostate cancer specific deaths and 4,600 deaths. On multivariable analysis suspicious digital rectal examination and abnormal prostate specific antigen were associated with a greater risk of clinically significant prostate cancer (HR 2.21, 95% CI 1.99-2.44 vs HR 5.48, 95% CI 5.05-5.96, p <0.001 and p <0.001) and prostate cancer specific mortality (HR 2.54, 95% CI 1.41-4.58 vs HR 5.23, 95% CI 3.08-8.88, p=0.002 and p <0.001), respectively. In a secondary analysis of a contemporary U.S. cohort, suspicious digital rectal examination and abnormal prostate specific antigen on routine screening were independently associated with clinically significant prostate cancer and prostate cancer specific mortality. However, additional research is needed to optimize screening protocols. Copyright © 2017 American Urological Association Education and Research, Inc. Published by Elsevier Inc. All rights reserved.

To update our previously published systematic review and meta-analysis by subjecting the literature on shoulder physical examination (ShPE) to careful analysis in order to determine each tests clinical utility. This review is an update of previous work, therefore the terms in the Medline and CINAHL search strategies remained the same with the exception that the search was confined to the dates November, 2006 through to February, 2012. The previous study dates were 1966 - October, 2006. Further, the original search was expanded, without date restrictions, to include two new databases: EMBASE and the Cochrane Library. The Quality Assessment of Diagnostic Accuracy Studies, version 2 (QUADAS 2) tool was used to critique the quality of each new paper. Where appropriate, data from the prior review and this review were combined to perform meta-analysis using the updated hierarchical summary receiver operating characteristic and bivariate models. Since the publication of the 2008 review, 32 additional studies were identified and critiqued. For subacromial impingement, the meta-analysis revealed that the pooled sensitivity and specificity for the Neer test was 72% and 60%, respectively, for the Hawkins-Kennedy test was 79% and 59%, respectively, and for the painful arc was 53% and 76%, respectively. Also from the meta-analysis, regarding superior labral anterior to posterior (SLAP) tears, the test with the best sensitivity (52%) was the relocation test; the test with the best specificity (95%) was Yergason's test; and the test with the best positive likelihood ratio (2.81) was the compression-rotation test. Regarding new (to this series of reviews) ShPE tests, where meta-analysis was not possible because of lack of sufficient studies or heterogeneity between studies, there are some individual tests that warrant further investigation. A highly specific test (specificity >80%, LR+ ≥ 5.0) from a low bias study is the passive distraction test for a SLAP lesion. This test may rule in a SLAP lesion when positive. A sensitive test (sensitivity >80%, LR- ≤ 0.20) of note is the shoulder shrug sign, for stiffness-related disorders (osteoarthritis and adhesive capsulitis) as well as rotator cuff tendinopathy. There are six additional tests with higher sensitivities, specificities, or both but caution is urged since all of these tests have been studied only once and more than one ShPE test (ie, active compression, biceps load II) has been introduced with great diagnostic statistics only to have further research fail to replicate the results of the original authors. The belly-off and modified belly press tests for subscapularis tendinopathy, bony apprehension test for bony instability, olecranon-manubrium percussion test for bony abnormality, passive compression for a SLAP lesion, and the lateral Jobe test for rotator cuff tear give reason for optimism since they demonstrated both high sensitivities and specificities reported in low bias studies. Finally, one additional test was studied in two separate papers. The dynamic labral shear may be sensitive for SLAP lesions but, when modified, be diagnostic of labral tears generally. Based on data from the original 2008 review and this update, the use of any single ShPE test to make a pathognomonic diagnosis cannot be unequivocally recommended. There exist some promising tests but their properties must be confirmed in more than one study. Combinations of ShPE tests provide better accuracy, but marginally so. These findings seem to provide support for stressing a comprehensive clinical examination including history and physical examination. However, there is a great need for large, prospective, well-designed studies that examine the diagnostic accuracy of the many aspects of the clinical examination and what combinations of these aspects are useful in differentially diagnosing pathologies of the shoulder.

The objectives of this study were: 1) to identify the ultrasonographic (US) abnormalities and 2) to compare the findings of physical examination with US findings in rheumatoid arthritis (RA) patients with shoulder pain. We studied 30 RA patients. Physical examination was performed systemically as follows: 1) area of tenderness; 2) range of passive and active shoulder motion; 3) impingement tests; 4) maneuvers for determining the location of the tendon lesions. US investigations included the biceps, the supraspinatus, infraspinatus, and subscapularis tendons; the subacromial-subdeltoid bursa; and the glenohumeral and acromioclavicular joints. Thirty RA patients with 35 painful and 25 non-painful shoulders were examined. The range of motion affected the most by shoulder pain was abduction. The most frequent US finding of shoulder joint was effusion in the long head of the biceps tendon. Among the rotator cuff tendons, subscapularis was the most frequently involved. Tendon tear was also common among non-painful shoulders. Physical examination used for the diagnosis of shoulder pain had low sensitivity and specificity for detecting abnormalities in the rheumatoid shoulder joint. In conclusion, US abnormalities showed frequent tendon tears in our RA patients. Physical examination had low sensitivity and specificity for detecting rotator cuff tear in the rheumatoid shoulder joint. PMID:17728506

Sixty-eight patients with various types of gastritis, 23 patients with normal stomachs, and four patients with other gastric diseases were examined in a prospective study to assess the sensitivity and specificity of single-contrast (SC) and double-contrast (DC) upper gastrointestinal examinations in the evaluation of gastritis. All patients underwent endoscopy with biopsy followed first by DC and then by SC radiography. The respective sensitivities of SC and DC radiography were 58% and 72% for all examinations and 59% and 77% for adequate examinations only. The respective specificities were 59% and 55% based on all examinations. Useful radiographic features included polypoid defectsmore » and erosions detected by both methods, abnormal folds and flattened margins detected by the SC technique, and narrowed lumen and crenulated margins detected by the DC technique. In 93% of all cases, the correct diagnosis was based on two or more of these radiographic features. According to this study, the radiographic sensitivity in the detection of gastritis is reliable only in cases of moderate-to-severe disease and only when based on findings of the DC examination. Neither SC nor DC radiography should be used as the primary screening method for patients with suspected gastritis, and the radiographic diagnosis should be restricted to the terms ''erosive'' or ''nonerosive gastritis.''« less

Studies examining experts' superiority within domain-specific structured pattern recall tasks have typically had athletes perform them at rest, which is far different from how they are executed in their sport. The aim of this study was to investigate whether performing these tasks under different physical exercise intensities influenced pattern recall results of experts, advanced and novices. In two experiments, 68 participants (experiment 1: n = 33; experiment 2: n = 35) were tested using a handball-specific pattern recall task both at rest and during physical exercise. Physical exercises of 60 % heart rate reserve (constant workload: experiment 1) and of 86.5-90 % HRmax (handball-specific interval load: experiment 2) were induced. Results of both experiments revealed significant group differences with experts recalling patterns more accurately than novices but no significant within-subject differences for the two conditions and no interaction between both factors. Our findings replicate prior research concerning perceptual-cognitive expertise in structured specific pattern recall tasks. However, the lack of intergroup differences between the two conditions or interactions was surprising, suggesting sport-specific pattern recall skill is robust to changes in exercise stimuli. Future work is needed to further examine the impact of "physiological specificity" on perceptual-cognitive expertise.

Background: Specific cognitive rehabilitation in multiple sclerosis (MS) resulted to be effective compared to no treatment. So far the possible role of an aspecific psychological intervention on cognition has not been investigated. Objective: The aim of the SMICT RCT was to compare the efficacy of a specific cognitive training with an aspecific psychological intervention in relapsing-remitting MS patients. Methods: From a sample of 150 patients, with the same disability and immunomodulatory therapy, submitted to neuropsychological examination, 45 impaired in at least one test were included and 41 randomized to have either a specific cognitive training for the impaired function (22) or to an aspecific psychological intervention (19) for 4 months, starting after baseline examination. Neuropsychological tests and functional scales were administered at baseline and 1 year later. Results: After 1 year, the mean number of pathological tests was significantly lower in the specific treatment group, compared to the aspecific group. Memory and attention/speeded information processing functions were mostly improved. Depression and quality of life were not different between groups at follow up. Conclusion: Our study demonstrates that an intensive and domain specific cognitive approach results to be more effective than aspecific psychological intervention in patients with MS. PMID:25628596

To evaluate the diagnostic value and potential therapeutic impact of Peking Union Medical College Hospital critical ultrasonic management (PCUM) in the early management of critically ill patients with acute respiratory failure (ARF). Patients admitted into the ICU of Peking Union Medical College Hospital for ARF were consecutively recruited over a 18-month period. Patients were randomly divided into conventional group and PCUM group (critical care ultrasonic examination was added in addition to conventional examinations). The two groups were compared with respect to time to preliminary diagnosis, time to final diagnosis, diagnostic accuracy, time to treatment response, time to other examination. A total of 187 patients were included in this study. The two groups showed no significant differences in general clinical information or final diagnosis (P > 0.05). The PCUM group had a shorter time to preliminary diagnosis, time to final diagnosis, time to treatment response, time to X-ray/CT examination, and a higher diagnostic accuracy than the conventional group (P < 0.001). PCUM had high sensitivity and specificity for the diagnosis of acute respiratory distress syndrome (ARDS) (sensitivity 92.0%, specificity 98.5%), acute pulmonary edema (sensitivity 94.7%, specificity 96.1%), pulmonary consolidation (sensitivity 85.7%, specificity 98.6%), COPD/asthma (sensitivity 84.2%, specificity 98.7%). The PCUM is seem to be an attractive complementary diagnostic tool and able to contribute to an early therapeutic decision for the patients with ARF.

Murnane and Phelps (1993) recommend word pair presentations in local environmental context (EC) studies to prevent associations being formed between successively presented items and their ECs and a consequent reduction in the EC effect. Two experiments were conducted to assess the veracity of this assumption. In Experiment 1, participants memorised single words or word pairs, or categorised them as natural or man made. Their free recall protocols were examined to assess any associations established between successively presented items. Fewest associations were observed when the item-specific encoding task (i.e., natural or man made categorisation of word referents) was applied to single words. These findings were examined further in Experiment 2, where the influence of encoding instructions and stimulus presentation on local EC dependent recognition memory was examined. Consistent with recognition dual-process signal detection model predictions and findings (e.g., Macken, 2002; Parks & Yonelinas, 2008), recollection sensitivity, but not familiarity sensitivity, was found to be local EC dependent. However, local EC dependent recognition was observed only after item-specific encoding instructions, irrespective of stimulus presentation. These findings and the existing literature suggest that the use of single word presentations and item-specific encoding enhances local EC dependent recognition.

Background Previous studies have examined participation in specific leisure-time physical activities (PA) among US adults. The purpose of this study was to identify specific activities that contribute substantially to total volume of leisure-time PA in US adults. Methods Proportion of total volume of leisure-time PA moderate-equivalent minutes attributable to 9 specific types of activities was estimated using self-reported data from 21,685 adult participants (≥ 18 years) in the National Health and Nutrition Examination Survey 1999–2006. Results Overall, walking (28%), sports (22%), and dancing (9%) contributed most to PA volume. Attributable proportion was higher among men than women for sports (30% vs. 11%) and higher among women than men for walking (36% vs. 23%), dancing (16% vs. 4%), and conditioning exercises (10% vs. 5%). The proportion was lower for walking, but higher for sports, among active adults than those insufficiently active and increased with age for walking. Compared with other racial/ethnic groups, the proportion was lower for sports among non-Hispanic white men and for dancing among non-Hispanic white women. Conclusions Walking, sports, and dance account for the most activity time among US adults overall, yet some demographic variations exist. Strategies for PA promotion should be tailored to differences across population subgroups. PMID:27335226

Test anxiety: a cross-cultural perspective.
Bodas, Jaee; Ollendick, Thomas H
2005-03-01
The present paper examines test anxiety from a cross-cultural perspective with specific reference to the Indian and American cultures. The construct of test anxiety has been examined in many cultures all over the world. In this review, the importance of understanding and incorporating contextual factors in cross-cultural research is emphasized. Moreover, some of the methodological issues related to investigating culture-behavior relationship are discussed. Specifically, the derived-etic approach for conducting cross-cultural research is espoused. Then, research findings from western, cross-cultural, and Indian studies on test anxiety are reviewed. Consistent with the individualistic orientation of the western society, much of the research in the western world has adopted a de-contextualized approach. Inasmuch as many of the cross-cultural and Indian studies on test anxiety have their roots in western research, they have ignored the cultural context as well. To address this void, contextual variables relevant to test anxiety in the Indian setting are examined and hypotheses regarding the nature of test anxiety in Indian children are proposed. Finally, a research agenda is presented to examine these hypotheses using a derived-etic approach.

Tham and Tegner proposed the Baking Tray Task (BTT) as a fast simple assessment test for detecting spatial negligence. However, very few studies have examined its validity as a diagnostic test. To analyse the diagnostic validity of the BTT by measuring its specificity and sensitivity in a sample of subjects with right hemisphere strokes. Forty-eight patients with right hemisphere vascular lesions were distributed in two groups (negligence group, n = 35; non-negligence group, n = 13) according to the scores obtained in a battery of visuospatial examination tests. The participants' performance on the BTT was compared with that of a healthy control group (n = 12). The results showed a high level of sensitivity of the BTT, but low specificity. The performance on the BTT of eight of the 13 members of the non-negligence group was suggestive of negligence. The BTT has proved to be a sensitive test for the detection of spatial negligence. Yet, based on its low specificity, its use alone as a single diagnostic test is not recommended.

Our objective was to examine the predictive validity of the American Board of Family Medicine's (ABFM) In-Training Examination (ITE) with regard to predicting outcomes on the ABFM certification examination. This study used a repeated measures design across three levels of medical training (PGY1--PGY2, PGY2--PGY3, and PGY3--initial certification) with three different cohorts (2010--2011, 2011--2012, and 2012--2013) to examine: (1) how well the residents' ITE scores correlated with their test scores in the following year, (2) what the typical score increase was across training years, and (3) what was the sensitivity, specificity, positive predictive value, and negative predictive value of the PGY3 scores with regard to predicting future results on the MC-FP Examination. ITE scores generally correlate at about .7 with the following year's ITE or with the following year's certification examination. The mean growth from PGY1 to PGY2 was 52 points, from PGY2 to PGY3 was 34 points, and from PGY3 to initial certification was 27 points. The sensitivity, specificity, positive predictive value, and negative predictive value were .91, .47, .96, and .27, respectively. The ITE is a useful predictor of future ITE and initial certification examination performance.
Gender plays no role in student ability to perform on computer-based examinations.

To see if there is a difference in performance when students switch from traditional paper-and-pencil examinations to computer-based examinations, and to determine whether there are gender differences in student performance in these two examination formats. This study involved first year medical students at the University of Illinois at Urbana-Champaign over three Academic Years 2002-03/2003-04 and 2003-05. Comparisons of student performance by overall class and gender were made. Specific comparisons within courses that utilized both the paper-and-pencil and computer formats were analyzed. Overall performance scores for students among the various Academic Years revealed no differences between exams given in the traditional pen-and-paper and computer formats. Further, when we looked specifically for gender differences in performance between these two testing formats, we found none. The format for examinations in the courses analyzed does not affect student performance. We find no evidence for gender differences in performance on exams on pen-and-paper or computer-based exams.

The future of total knee arthroplasty (TKA) surgery will involve planning that incorporates more patient-specific characteristics. Despite known biological, morphological, and functional differences between men and women, there has been little investigation into knee joint biomechanical and neuromuscular differences between men and women with osteoarthritis, and none that have examined sex-specific biomechanical and neuromuscular responses to TKA surgery. The objective of this study was to examine sex-associated differences in knee kinematics, kinetics and neuromuscular patterns during gait before and after TKA. Fifty-two patients with end-stage knee OA (28 women, 24 men) underwent gait and neuromuscular analysis within the week prior to and one year after surgery. A number of sex-specific differences were identified which suggest a different manifestation of end-stage knee OA between the sexes. Copyright © 2014 Elsevier Inc. All rights reserved.

The specificity of the association between 2 parenting behaviors (warmth and supervision) and 2 indicators, aggressive behavior and depressive symptoms, of major child outcomes (externalizing problems and internalizing problems) was examined among 196 inner-city African American mothers and their school age children. Given the growing number of African American families affected by HIV/AIDS and demonstrated compromises in parenting associated with maternal infection, the moderating role of maternal HIV/AIDS was also examined. Findings from longitudinal analyses supported the specificity of maternal warmth but not of maternal supervision. Maternal warmth was a stronger predictor of decreases in child aggressive behavior than of decreases in depressive symptoms. In addition, maternal warmth was a stronger predictor of decreases in aggressive behavior than was maternal supervision. Parenting specificity was not moderated by maternal HIV/AIDS. Clinical implications and future research directions are discussed. (c) 2008 APA, all rights reserved.

A JPL development activity was initiated in FY 1999 for the purpose of examining and evaluating technologies that could materially improve future (i.e., beyond the 2005 launch) Mars sample return missions. The scope of the technology review was comprehensive and end-to-end; the goal was to improve mass, cost, risk, and scientific return. A specific objective was to assess approaches to sample return with only one Earth launch. While the objective of the study was specifically for sample-return, in-situ missions can also benefit from using many of the technologies examined.

Research involving military service members has shown a strong relationship between combat experiences and increased risk for posttraumatic stress disorder (PTSD) and other mental health problems. Comparatively little research has examined the relationship between combat experiences, PTSD, aggression, and unethical conduct on the battlefield, although news stories sometimes suggest links between unethical conduct and disorders such as PTSD. This study systematically examined whether unethical conduct is a proxy for aggression and whether specific combat experiences and PTSD are independently associated with unethical behavior. The results of this study indicate that aggression (β = 0.30) and specific combat experiences (particularly, witnessing war atrocities [β = 0.14] and fighting [β = 0.13]) are much more strongly associated with unethical conduct than is PTSD (β = 0.04).

There has been an increasing incidence of Lyme disease (LD) in Canada and the United States corresponding to the expanding range of the Ixodes tick vector and Lyme disease agent (Borrelia burgdorferi sensu stricto). There are many diagnostic tests for LD available in North America, all of which have some performance issues, and physicians are concerned about the appropriate use and interpretation of these tests. The objective of this systematic review is to summarize the North American evidence on the accuracy of diagnostic tests and test regimes at various stages of LD. Included in the review are 48 studies on diagnostic tests used in North America published since 1995. Thirteen studies examined a two-tier serological test protocol vs. clinical diagnosis, 24 studies examined single assays vs. clinical diagnosis, 9 studies examined single immunoblot vs. clinical diagnosis, 7 studies compared culture or PCR direct detection methods vs. clinical diagnosis, 22 studies compared two or more tests with each other and 8 studies compared a two-tiered serological test protocol to another test. Recent studies examining the sensitivity and specificity of various test protocols noted that the Immunetics® C6 B. burgdorferi ELISA™ and the two tier approach have superior specificity compared to proposed replacements, and the CDC recommended western blot algorithm has equivalent or superior specificity over other proposed test algorithms. There is a dramatic increase in test sensitivity with progression of B. burgdorferi infection from early to late LD. Direct detection methods, culture and PCR of tissue or blood samples were not as sensitive or timely compared to serological testing. It was also noted that there are a large number of both commercial (n = 42) and in-house developed tests used by private laboratories which have not been evaluated in the primary literature.

Screening methods sensitive to movement strategies that increase anterior cruciate ligament (ACL) loads are likely to be effective in identifying athletes at-risk of ACL injury. Current ACL injury risk screening methods are yet to be evaluated for their ability to identify athletes' who exhibit high-risk lower limb mechanics during sport-specific maneuvers associated with ACL injury occurrences. The purpose of this study was to examine the efficacy of two ACL injury risk screening methods in identifying high-risk lower limb mechanics during a sport-specific landing task. Thirty-two female athletes were screened using the Landing Error Scoring System (LESS) and Tuck Jump Assessment. Participants' also completed a sport-specific landing task, during which three-dimensional kinematic and kinetic data were collected. One-dimensional statistical parametric mapping was used to examine the relationships between screening method scores, and the three-dimensional hip and knee joint rotation and moment data from the sport-specific landing. Higher LESS scores were associated with reduced knee flexion from 30 to 57 ms after initial contact (P = 0.003) during the sport-specific landing; however, no additional relationships were found. These findings suggest the LESS and Tuck Jump Assessment may have minimal applicability in identifying athletes' who exhibit high-risk landing postures in the sport-specific task examined. © 2016 John Wiley & Sons A/S.

Identity Profiles in Lesbian, Gay, and Bisexual Youth: The Role of Family Influences
Bregman, Hallie R.; Malik, Neena M.; Page, Matthew J. L.; Makynen, Emily; Lindahl, Kristin M.
2012-01-01
Sexual identity development is a central task of adolescence and young adulthood and can be especially challenging for sexual minority youth. Recent research has moved from a stage model of identity development in lesbian, gay, and bisexual (LGB) youth to examining identity in a non-linear, multidimensional manner. In addition, although families have been identified as important to youth's identity development, limited research has examined the influence of parental responses to youth's disclosure of their LGB sexual orientation on LGB identity. The current study examined a multidimensional model of LGB identity and its links with parental support and rejection. One hundred and sixty-nine LGB adolescents and young adults (ages 14–24, 56% male, 48% gay, 31% lesbian, 21% bisexual) described themselves on dimensions of LGB identity and reported on parental rejection, sexuality-specific social support, and non-sexuality-specific social support. Using latent profile analysis (LPA), two profiles were identified, indicating that youth experience both affirmed and struggling identities. Results indicated that parental rejection and sexuality-specific social support from families were salient links to LGB identity profile classification, while non-sexuality specific social support was unrelated. Parental rejection and sexuality-specific social support may be important to target in interventions for families to foster affirmed LGB identity development in youth. PMID:22847752
Sensitivity and specificity of mammographic screening as practised in Vermont and Norway
Hofvind, S; Geller, B M; Skelly, J; Vacek, P M
2012-01-01
Objective The aim of this study was to examine the sensitivity and specificity of screening mammography as performed in Vermont, USA, and Norway. Methods Incident screening data from 1997 to 2003 for female patients aged 50–69 years from the Vermont Breast Cancer Surveillance System (116 996 subsequent screening examinations) and the Norwegian Breast Cancer Screening Program (360 872 subsequent screening examinations) were compared. Sensitivity and specificity estimates for the initial (based on screening mammogram only) and final (screening mammogram plus any further diagnostic imaging) interpretations were directly adjusted for age using 5-year age intervals for the combined Vermont and Norway population, and computed for 1 and 2 years of follow-up, which ended at the time of the next screening mammogram. Results For the 1-year follow-up, sensitivities for initial assessments were 82.0%, 88.2% and 92.5% for 1-, 2- and >2-year screening intervals, respectively, in Vermont (p=0.022). For final assessments, the values were 73.6%, 83.3% and 81.2% (p=0.047), respectively. For Norway, sensitivities for initial assessments were 91.0% and 91.3% (p=0.529) for 2- and >2-year intervals, and 90.7% and 91.3%, respectively, for final assessments (p=0.630). Specificity was lower in Vermont than in Norway for each screening interval and for all screening intervals combined, for both initial (90.6% vs 97.8% for all intervals; p<0.001) and final (98.8% vs 99.5% for all intervals; p<0.001) assessments. Conclusion Our study showed higher sensitivity and specificity in a biennial screening programme with an independent double reading than in a predominantly annual screening program with a single reading. Advances in knowledge This study demonstrates that higher recall rates and lower specificity are not always associated with higher sensitivity of screening mammography. Differences in the screening processes in Norway and Vermont suggest potential areas for improvement in the latter. PMID:22993383

Researchers have postulated associations between childhood trauma and delinquency, but few have examined the direction of these relationships prospectively and, specifically, with samples of delinquent girls. The purpose of this study was to examine the relationship between traumatic events and delinquency for girls in the juvenile justice system using a cross-lagged model. Developmental differences in associations as a function of high school entry status were also examined. The sample included 166 girls in the juvenile justice system who were mandated to community-based out-of-home care due to chronic delinquency. Overall, study results provide evidence that trauma and delinquency risk pathways vary according to high school entry status. Implications for future research and practice are discussed.

Culturally specific dance has the potential to generate health benefits but is seldom used even among studies advocating culturally specific interventions. This study examined the components of self-efficacy and social support as mediators between culturally specific dance and lifestyle physical activity in African American women (N = 126). An experimental design compared intervention and control groups for mediating effects of self-efficacy and social support on lifestyle physical activity. Findings indicated that only outcome expectations and social support from friends mediated effects. Culturally specific dance is a first step in encouraging African American women to become more physically active and improve health outcomes. The implications are that culturally specific dance programs can improve health outcomes by including members of underserved populations. PMID:18763475

Participants' dentists were asked to complete a questionnaire about their practice characteristics. Data Collection/Extraction Methods In-person interviews and clinical examinations were conducted at baseline, 24, and 48 months, with 6-monthly telephone interviews in between. A single multivariate (four radiographic service outcomes) multivariable (multiple explanatory covariates) logistic regression was used to model service receipts. Principal Findings These practice characteristics were significantly associated with patient-specific receipt of radiographic services: number of different practices attended during follow-up; dentist's rating of how busy the practice was; typical waiting time for a new patient examination; practice size; percentage of patients that the dentist reported as interested in details about the condition of their mouths; percentage of African American patients in the practice; percentage of patients in the practice who do not have dental insurance; and dentist's agreement with a statement regarding whether patients should be dismissed from the practice. Effects had differential magnitudes and directions of effect, depending upon radiograph type. Conclusions Practice characteristics were significantly associated with patient-specific receipt of services. These effects were independent of patient-specific disease level and patient-specific sociodemographic characteristics, suggesting that practitioners do influence receipt of these diagnostic services. These findings are consistent with the conclusion that practitioners act in response to a mix of patients' interests, economic self-interests, and their own treatment preferences. PMID:16987308

The application of complex neurophysiological examination including motor evoked potentials (MEP) for pre- and postoperative evaluation of patients experiencing acute sciatica. The assessment of sensitivity and specificity of needle electromyography, MEP, and H-reflex examinations. The comparative analysis of preoperative and postoperative neurophysiological examination. In spite of the fact that complex neurophysiological diagnostic tools seem to be important for interpretation of incompatible results of neuroimaging and clinical examination, especially in the patients qualified for surgical treatment, their application has never been completely analyzed and documented. Pre- and postoperative electromyography, electroneurography, F-waves, H-reflex, and MEP examination were performed in 23 patients with confirmed disc-root conflict at lumbosacral spine. Clinical evaluation included examination of sensory perception for L5-S1 dermatomes, muscles strength with Lovett's scale, deep tendon reflexes, pain intensity with visual analogue scale, and straight leg raising test. Sensitivity of electromyography at rest and MEP examination for evaluation of L5-S1 roots injury was 22% to 63% and 31% to 56% whereas specificity was 71% to 83% and 57% to 86%, respectively. H-reflex sensitivity and specificity for evaluation of S1 root injury were 56% and 67%, respectively. A significant improvement of root latency parameter in postoperative MEP studies as compared with preoperative was recorded for L5 (P = 0.039) and S1 root's levels (P = 0.05). The analysis of the results from neurophysiological tests together with neuroimaging and clinical examination allow for a precise preoperative indication of the lumbosacral roots injury and accurate postoperative evaluation of patients experiencing sciatica. 3.

Pathways to Firesetting for Mentally Disordered Offenders: A Preliminary Examination.
Tyler, Nichola; Gannon, Theresa A
2017-06-01
The current study aimed to investigate the specific pathways in the offence process for mentally disordered firesetters. In a previous study, an offence chain model was constructed (i.e., the Firesetting Offence Chain for Mentally Disordered Offenders, FOC-MD) using offence descriptions obtained from 23 mentally disordered firesetters, detailing the sequence of contextual, behavioural, affective, and cognitive factors that precipitate an incidence of firesetting for this population. The current study examines the prevalence of the specific pathways to firesetting for the original 23 mentally disordered firesetters and a further sample of 13 mentally disordered firesetters. Three distinct pathways to firesetting are identified within the FOC-MD: fire interest-childhood mental health, no fire interest-adult mental health, fire interest-adult mental health. In this article, we describe these three pathways in detail using illustrative case studies. The practice implications of these identified pathways are also discussed.
Zebrafish embryos as a screen for DNA methylation modifications after compound exposure

Modified epigenetic programming early in life is proposed to underlie the development of an adverse adult phenotype, known as the Developmental Origins of Health and Disease (DOHaD) concept. Several environmental contaminants have been implicated as modifying factors of the developing epigenome. This underlines the need to investigate this newly recognized toxicological risk and systematically screen for the epigenome modifying potential of compounds. In this study, we examined the applicability of the zebrafish embryo as a screening model for DNA methylation modifications. Embryos were exposed from 0 to 72 h post fertilization (hpf) to bisphenol-A (BPA), diethylstilbestrol, 17α-ethynylestradiol, nickel, cadmium, tributyltin,more » arsenite, perfluoroctanoic acid, valproic acid, flusilazole, 5-azacytidine (5AC) in subtoxic concentrations. Both global and site-specific methylation was examined. Global methylation was only affected by 5AC. Genome wide locus-specific analysis was performed for BPA exposed embryos using Digital Restriction Enzyme Analysis of Methylation (DREAM), which showed minimal wide scale effects on the genome, whereas potential informative markers were not confirmed by pyrosequencing. Site-specific methylation was examined in the promoter regions of three selected genes vasa, vtg1 and cyp19a2, of which vasa (ddx4) was the most responsive. This analysis distinguished estrogenic compounds from metals by direction and sensitivity of the effect compared to embryotoxicity. In conclusion, the zebrafish embryo is a potential screening tool to examine DNA methylation modifications after xenobiotic exposure. The next step is to examine the adult phenotype of exposed embryos and to analyze molecular mechanisms that potentially link epigenetic effects and altered phenotypes, to support the DOHaD hypothesis. - Highlights: • Compound induced effects on DNA methylation in zebrafish embryos • Global methylation not an informative biomarker • Minimal genome wide site specific changes as detected with DREAM • Compound/class specific effects suggested by pyrosequence of specific targets • Zebrafish embryo may be a screening model for epigenetic effects.« less

Patient history and physical examination are frequently used procedures to diagnose chronic low back pain (CLBP) originating from the facet joints, although the diagnostic accuracy is controversial. The aim of this systematic review is to determine the diagnostic accuracy of patient history and/or physical examination to identify CLBP originating from the facet joints using diagnostic blocks as reference standard. We searched MEDLINE, EMBASE, CINAHL, Web of Science and the Cochrane Collaboration database from inception until June 2016. Two review authors independently selected studies for inclusion, extracted data and assessed the risk of bias. We calculated sensitivity and specificity values, with 95% confidence intervals (95% CI). Twelve studies were included, in which 129 combinations of index tests and reference standards were presented. Most of these index tests have only been evaluated in single studies with a high risk of bias. Four studies evaluated the diagnostic accuracy of the Revel's criteria combination. Because of the clinical heterogeneity, results were not pooled. The published sensitivities ranged from 0.11 (95% CI 0.02-0.29) to 1.00 (95% CI 0.75-1.00), and the specificities ranged from 0.66 (95% CI 0.46-0.82) to 0.91 (95% CI 0.83-0.96). Due to clinical heterogeneity, the evidence for the diagnostic accuracy of patient history and/or physical examination to identify facet joint pain is inconclusive. Patient history and physical examination cannot be used to limit the need of a diagnostic block. The validity of the diagnostic facet joint block should be studied, and high quality studies are required to confirm the results of single studies.

In much feminist literature, patriarchy has often been studied as a predictive variable for attitudes toward or acts of violence against women. However, rarely has patriarchy been examined as an outcome across studies. The current study works toward filling this gap by examining several individual-and neighborhood-level factors that might influence patriarchy. Specifically, this research seeks to determine if neighborhood-level attributes related to socioeconomic status, family composition, and demographic information affect patriarchal views after individual-level correlates of patriarchy were controlled. Findings suggest that factors at both the individual- and neighborhood levels, particularly familial characteristics and dynamics, do influence the endorsement of patriarchal views.

In adolescent athletes, low back pain has a 1-year prevalence of 57% and causes include spondylolysis and spondylolisthesis. An accurate diagnosis enables healing, prevention of progression and return to sport. To evaluate the diagnostic utility of patient history and physical examination data to identify spondylolysis and/or spondylolisthesis in athletes. Systematic review was undertaken according to published guidelines, and reported in line with PRISMA. Key databases were searched up to 13/11/15. athletic population with LBP, patient history and/or physical examination accuracy data for spondylolysis and/or spondylolisthesis, any study design including raw data. Two reviewers independently assessed risk of bias (ROB) using QUADAS-2. A data extraction sheet was pre-designed. Pooling of data and investigation for heterogeneity enabled a qualitative synthesis of data across studies. Of the eight included studies, two were assessed as low ROB, one of which also had no concerns regarding applicability. Age (<20 years) demonstrated 81% sensitivity and 44% specificity and gender (male) 73% sensitivity and 57% specificity for spondylolysis. Difficulty falling asleep, waking up because of pain, pain worse with sitting and walking all have sensitivity >75% for spondylolisthesis. Step-deformity palpation demonstrated 60-88% sensitivity and 87-100% specificity for spondylolisthesis. The one-legged hyperextension test was not supported for spondylolysis (sensitivity 50-73%, specificity 0-87%). No recommendations can be made utilising patient history data. Based on one low ROB study, step deformity palpation may be useful in diagnosing spondylolisthesis. No physical tests demonstrated diagnostic utility for spondylolysis. Further research is required.

Guidelines from the NCCN ® (National Comprehensive Cancer Network®) advocate digital rectal examination screening only in men with elevated prostate specific antigen. We investigated the effect of prostate specific antigen on the association of digital rectal examination and clinically significant prostate cancer in a large American cohort. We evaluated the records of the 35,350 men who underwent digital rectal examination in the screening arm of the Prostate, Lung, Colorectal and Ovarian Cancer Screening trial for the development of clinically significant prostate cancer (Gleason 7 or greater). Followup was 343,273 person-years. The primary outcome was the rate of clinically significant prostate cancer among men with vs without suspicious digital rectal examination. We performed competing risks regression to evaluate the interaction between time varying suspicious digital rectal examination and prostate specific antigen. A total of 1,713 clinically significant prostate cancers were detected with a 10-year cumulative incidence of 5.9% (95% CI 5.6-6.2). Higher risk was seen for suspicious vs nonsuspicious digital rectal examination. Increases in absolute risk were small and clinically irrelevant for normal (less than 2 ng/ml) prostate specific antigen (1.5% vs 0.7% risk of clinically significant prostate cancer at 10 years), clinically relevant for elevated (3 ng/ml or greater) prostate specific antigen (23.0% vs 13.7%) and modestly clinically relevant for equivocal (2 to 3 ng/ml) prostate specific antigen (6.5% vs 3.5%). Digital rectal examination demonstrated prognostic usefulness when prostate specific antigen was greater than 3 ng/ml, limited usefulness for less than 2 ng/ml and marginal usefulness for 2 to 3 ng/ml. These findings support the restriction of digital rectal examination to men with higher prostate specific antigen as a reflex test to improve specificity. It should not be used as a primary screening modality to improve sensitivity. Copyright © 2018 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Age of onset, callous-unemotional (CU) traits and anger dysregulation have separately been proposed as relevant factors in explaining the heterogeneity of antisocial behaviour (ASB). Taking a dimensional perspective, this study examined the specific contributions and the mutual influences (i.e., interactions) of these three characteristics on specific dimensions of ASB (i.e., criminal behaviours and externalizing symptoms). Assessments were conducted on 536 youths from institutions with the youth psychopathic traits inventory (CU traits), the Massachusetts youth screening instrument-second version (anger dysregulation), the criminology questionnaire (criminal behaviours) and the child behavior checklist (externalizing symptoms), rated by both the youths and their carers. Using Bayes as estimators, the results revealed that the number and frequency of crimes (and, more specifically, damage to property, property offenses and media crimes) were explained by a specific contribution of each factor (age of onset, CU traits and anger dysregulation). Additionally, the interactions between age of onset and CU traits or anger dysregulation were relevant predictors of some types of crimes (i.e., damage to property, property offences and media crimes). Furthermore, when rated by youths, externalizing symptoms were explained by CU traits and anger dysregulation. However, when rated by the carer, anger dysregulation was more important in explaining externalizing symptoms. This study highlights the importance of considering these factors altogether and the value of using a dimensional perspective when examining the structure of ASB in youths. Consequently, future classifications should take into account the mutual account of these characteristics, which were previously studied separately.

There is growing support for a bifactor conceptualization of the Anxiety Sensitivity Index-3 (ASI-3; Taylor et al., 2007), consisting of a General factor and 3 domain-specific factors (i.e., Physical, Cognitive, Social). Earlier studies supporting a bifactor model of the ASI-3 used samples that consisted of predominantly White respondents. In addition, extant research has yet to support the incremental validity of the Physical domain-specific factor while controlling for the General factor. The present study is an examination of a bifactor model of the ASI-3 and the measurement invariance of that model among an ethnoracially diverse sample of primary-care patients (N = 533). Results from multiple-group confirmatory factor analysis supported the configural and metric/scalar invariance of the bifactor model of the ASI-3 across self-identifying Black, Latino, and White respondents. The Physical domain-specific factor accounted for unique variance in an index of health anxiety beyond the General factor. These results provide support for the generalizability of a bifactor model of the ASI-3 across 3 ethnoracial groups, as well as indication of the incremental explanatory power of the Physical domain-specific factor. Study implications are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

This study modified the Revised Illness Perception Questionnaire (IPQ-R) in patients with persistent atrial fibrillation (AF). Qualitative interviews and think-aloud techniques informed modification of the IPQ-R to be specific to AF patients. Confirmatory Factor Analysis (CFA) (n = 198) examined the validity of the modified IPQ-R (AF-IPQ-R). Exploratory factor analysis (EFA) examined the new AF-triggers scale. Construct validity examined associations between the AF-IPQ-R, quality of life (QoL) and beliefs about medicines. Test-retest and internal reliability were examined. Interviews indicated that patients viewed triggers of AF rather than initial causes of illness as more applicable. Patients believed specific behaviours such as rest could control AF. Treatment control beliefs related to pharmacological and procedural treatments. These data were used to modify the IPQ-R subscales and to develop a triggers of AF scale. CFA indicated good model fit. EFA of the triggers scale indicated three factors: emotional; health behaviours; and over-exertion triggers. Expected correlations were found between the AF-IPQ-R, QoL and treatment beliefs, evidencing good construct validity. The AF-IPQ-R showed sound psychometric properties. It provides more detailed specification than the IPQ-R of beliefs that may help to understand poor QoL in AF patients, and guidance for future interventions in this area.

This study was designed to detect reticuloendotheliosis virus (REV) as a contaminant in fowl pox vaccines. A total of 30 fowl pox vaccine samples were examined for the presence of REV using both in vitro and in vivo methods. In in vitro testing, the fowl pox vaccine samples were inoculated into chicken embryo fibroblast cultures prepared from specific-pathogen-free embryonated chicken eggs, and the cultures were examined using PCR to detect REV. In in vivo testing, each fowl pox vaccine sample was inoculated into 5-d-old specific-pathogen-free chicks, which were kept under observation for up to 12 wk postinoculation; serum samples were collected at 15, 30, and 45 d postinoculation for the detection of REV-specific antibodies using ELISA. Tissue samples were collected at 8 and 12 wk postinoculation for histopathological examination. Of the tested vaccines, only one imported vaccine sample tested positive for REV using PCR. Serum samples collected from chicks infected with the PCR-positive vaccine batch also tested positive for REV-specific antibodies using ELISA. Histopathological examination of the liver, spleen, and bursa of Fabricius demonstrated the presence of tumor cells in these organs, confirming the results obtained using PCR and ELISA, and indicating that the sample was contaminated with REV. These data clearly indicate that the screening of all commercial poultry vaccines for viruses is an important factor in assuring the biosafety of animal vaccines.

Summary Objective To examine the long-term effects of bariatric surgery on female-specific cancer in women with obesity. Methods The prospective, matched Swedish Obese Subjects (SOS) study was designed to examine outcomes after bariatric surgery. This study includes 1420 women from the SOS cohort that underwent bariatric surgery and 1447 contemporaneously matched controls who received conventional obesity treatment. Age was 37–60 years and BMI was ≥38 kg/m2. Information on cancer events was obtained from the Swedish National Cancer Registry. Median follow-up time was 18.1 years (interquartile range 14.8–20.9 years, maximum 26 years). This study is registered with ClinicalTrials.gov, NCT01479452. Results Bariatric surgery was associated with reduced risk of overall cancer (hazard ratio=0.71; 95% CI 0.59–0.85; p<0.001). About half of the observed cancers were female-specific, and the incidence of these were lower in the surgery group compared with the control group (hazard ratio=0.68; 95% CI 0.52–0·88; p=0.004). The surgical treatment benefit with respect to female-specific cancer was significantly associated with baseline serum insulin (interaction p value=0.022), with greater relative treatment benefit in patients with medium or high insulin levels. Separate analyses of different types of female-specific cancers showed that bariatric surgery was associated with reduced risk of endometrial cancer (hazard ratio=0.56: 95% CI 0.35–0.89; p=0.014). Conclusions In this long-term study, bariatric surgery was associated with reduced risk of female-specific cancer, especially in women with hyperinsulinemia at baseline. PMID:28259424

Factors that contribute to the willingness to try "street hypnosis".
Davis, Orin C; Gao, Xuan
2014-01-01
This study takes a context-specific approach to examine people's willingness to try hypnosis under various conditions and the factors that contribute to their willingness. It examined 378 participants, who completed a web-based hypnosis survey. The results showed that people's willingness to try hypnosis varies by context. Specifically, people are more willing to try hypnosis when it is framed as "peak focus" rather than "hypnosis" and when they perceive the environment as being safer. Moreover, factors including participants' demographics, hypnotists' demographics (relative to the subjects'), participants' control bias, and knowledge of hypnosis affect people's degrees of willingness to try hypnosis, depending on the specific context. The results suggest further analysis of hypnosis occurring in public contexts and the effects it may have on attitudes and therapeutic outcomes.

The optoelectronic method is one of the most promising concepts of biophysical program of the diagnostics of CIN and cervical cancer. Objectives of the work are evaluation of sensitivity and specificity of the optoelectronic method in the detection of CIN and cervical cancer. The paper shows correlation between the pNOR number and sensitivity/specificity of the optoelectronic method. The study included 293 patients with abnormal cervical cytology result and the following examinations: examination with the use of the optoelectronic method — Truscreen, colposcopic examination, and histopathologic biopsy. Specificity of the optoelectronic method for LGSIL was estimated at 65.70%, for HGSIL and squamous cell carcinoma of cervix amounted to 90.38%. Specificity of the optoelectronic method used to confirm lack of cervical pathology was estimated at 78.89%. The field under the ROC curve for the optoelectronic method was estimated at 0.88 (95% CI, 0.84-0.92) which shows high diagnostic value of the test in the detection of HGSIL and squamous cell carcinoma. The optoelectronic method is characterised by high usefulness in the detection of CIN, present in the squamous epithelium and squamous cell carcinoma of cervix.

Accurate diagnosis of Plasmodium infection is crucial for prompt malaria treatment and surveillance. Microscopic examination has been widely applied as the gold standard for malaria diagnosis in most part of malaria endemic areas, but its diagnostic value has been questioned, particularly in submicroscopic malaria. In this study, the diagnostic performance of microscopic examination and nested polymerase chain reaction (PCR) was evaluated to establish optimal malaria diagnosis method in Myanmar. A total of 1125 blood samples collected from residents in the villages and towns located in Naung Cho, Pyin Oo Lwin, Tha Beik Kyin townships and Mandalay of Upper Myanmar were screened by microscopic examination and species-specific nested PCR method. Among the 1125 blood samples, 261 samples were confirmed to be infected with malaria by microscopic examination. Evaluation of the 1125 samples by species-specific nested PCR analysis revealed that the agreement between microscopic examination and nested PCR was 87.3% (261/299). Nested PCR successfully detected 38 Plasmodium falciparum or Plasmodium vivax infections, which were missed in microscopic examination. Microscopic examinations also either misdiagnosed the infected Plasmodium species, or did not detect mixed infections with different Plasmodium species in 31 cases. The nested PCR method is more reliable than conventional microscopic examination for the diagnosis of malaria infections, and this is particularly true in cases of mixed infections and submicroscopic infections. Given the observed higher sensitivity and specificity of nested PCR, the molecular method holds enormous promise in malaria diagnosis and species differentiation, and can be applied as an effective monitoring tool for malaria surveillance, control and elimination in Myanmar.

We prospectively assessed the incremental value of a pocket-sized echocardiography (PSE) device during cardiology consultations, in addition to physical examination, ECG reading, and chest x-ray. A total of 443 consecutive patients (53% men), referred for bedside consultations, underwent physical examination, ECG, and CXR, followed by PSE examination. The physician completed a detailed questionnaire (clinical and echocardiographic data, scanning time, abnormal results). Receiver operating characteristic (ROC) curve analysis was generated to test the predictive discrimination value of the different methods. The incremental value of PSE examination compared to clinical visit alone or combined with ECG results was expressed as a global chi-square value. The PSE examination did not influence the definitive diagnosis in only 23.5% of cases, while 25.3% of the diagnoses were confirmed and verified by PSE. The clinical diagnosis was enriched by PSE in 21.9% of cases, and the diagnosis was changed in 26.2%. The area under curve (AUC) of physical examination + ECG results (sensitivity: 80%; specificity: 67%) was significantly higher than physical examination alone (sensitivity: 75%; specificity: 62%) (P < 0.0002), and the AUC of PSE results (sensitivity: 88%; specificity: 86%) was significantly higher than physical examination + ECG results (P < 0.0001). The PSE results, combined with clinical and ECG results, had a significant incremental diagnostic value during cardiology consultation when compared to the clinical visit alone or with ECG results (P < 0.0001). PSE had an incremental diagnostic value during bedside cardiology consultation, increasing the number of appropriate diagnoses and reducing the routine use of echocardiography. © 2015, Wiley Periodicals, Inc.

Background Major depressive disorder (MDD) is associated with deficits in recalling specific autobiographical memories (AMs). Extensive research has examined the functional anatomical correlates of AM in healthy humans, but no studies have examined the neurophysiological underpinnings of AM deficits in MDD. The goal of the present study was to examine the differences in the hemodynamic response between patients with MDD and controls while they engage in AM recall. Method Participants (12 unmedicated MDD patients; 14 controls) underwent functional magnetic resonance imaging (fMRI) scanning while recalling AMs in response to positive, negative and neutral cue words. The hemodynamic response during memory recall versus performing subtraction problems was compared between MDD patients and controls. Additionally, a parametric linear analysis examined which regions correlated with increasing arousal ratings. Results Behavioral results showed that relative to controls, the patients with MDD had fewer specific (p=0.013), positive (p=0.030), highly arousing (p=0.036) and recent (p=0.020) AMs, and more categorical (p<0.001) AMs. The blood oxygen level-dependent (BOLD) response in the parahippocampus and hippocampus was higher for memory recall versus subtraction in controls and lower in those with MDD. Activity in the anterior insula was lower for specific AM recall versus subtraction, with the magnitude of the decrement greater in MDD patients. Activity in the anterior cingulate cortex was positively correlated with arousal ratings in controls but not in patients with MDD. Conclusions We replicated previous findings of fewer specific and more categorical AMs in patients with MDD versus controls. We found differential activity in medial temporal and prefrontal lobe structures involved in AM retrieval between MDD patients and controls as they engaged in AM recall. These neurophysiological deficits may underlie AM recall impairments seen in MDD. PMID:21798113

A random sample of 974 African-American and non-Hispanic white Medicare beneficiaries aged 65 and older living in west-central Alabama and participating in the University of Alabama at Birmingham Study of Aging, excluding those with reported diagnoses of dementia or with missing data. Function, based on self-reported difficulty in performing ADLs and IADLs, and cognition, using the MMSE. Multivariable linear regression models were used to test the association between function and cognition in race- and sex-specific groups after adjusting for covariates. Mini-Mental State Examination scores were modestly correlated with ADL and IADL difficulty in all four race- and sex-specific groups, with Pearson correlation coefficients ranging from −0.189 for non-Hispanic white women to −0.429 for African-American men. Correlations between MMSE and ADL or IADL difficulty in any of the race- and sex-specific groups were no longer significant after controlling for sociodemographic factors and comorbidities. Mini-Mental State Examination was not significantly associated with functional difficulty in older African-American and non-Hispanic white men and women after adjusting for sociodemographic factors and comorbidities, suggesting a mediating role in the relationship between cognition and function. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

Highlights: • We examined the effect of ERβ specific ligand on HIF-1 inhibition. • DPN down-regulates the ARNT protein levels in PC3 cells. • DPN did not show additional effect in ERβ transfected MCF-7 cells. • Our study shows that unliganded ERβ is sufficient to inhibit HIF-1 in systems of overexpression. - Abstract: Estrogen receptor (ER) β is predicted to play an important role in the prevention of breast cancer development and progression. We have previously shown that ERβ suppresses hypoxia inducible factor (HIF)-1-mediated transcription through aryl hydrocarbon receptor nuclear translocator (ARNT) degradation via ubiquitination processes. In this study, wemore » attempted to examine the effect of ERβ specific ligand on HIF-1 inhibition in ERβ positive PC3 cells and ERβ transfected MCF-7 cells. ERβ specific agonist diarylpropionitrile (DPN) stimulated estrogen response element (ERE)-luciferase activity in a similar fashion to estradiol in PC3 cells. We observed that DPN down-regulates the ARNT protein levels leading to an attenuation of hypoxia-induced hypoxia response element (HRE)-driven luciferase reporter gene activation in PC3 cells. Treatment of DPN reduced vascular endothelial growth factor (VEGF) expression and co-treatment with ERβ specific antagonist PHTPP abrogated the effect in PC3 cells. We then examined the effect of DPN in ERβ transfected MCF-7 cells. HIF-1 transcriptional activity repression by ERβ was not further reduced by DPN, as examined by HRE-driven luciferase assays. Expression of ERβ significantly decreased VEGF secretion and ARNT expression under hypoxic conditions. However, DPN did not additionally affect this suppression in MCF-7 cells transfected with ERβ. This result shows that unliganded ERβ is sufficient to inhibit HIF-1 in systems of overexpression.« less
