INTRODUCTION: This study aimed to determine and compare the effectiveness of the use of the dual-dimensional archwire and conventional rectangular archwire on tooth movement patterns when combined with various lengths of power arms. METHODS: Displacements of the maxillary central incisor and the deformation of the wire section were calculated when applying retraction forces from different lengths of power arms using the finite element method. RESULTS: Torque control of the incisor could be carried out more effectively when using the dual-dimensional archwire combined with long power arms than with the rectangular archwire...

In 2021, there were about 17,000 victims of human trafficking in the United States. We present a case of a 28-year-old sex trafficking victim who was forced to swallow 2 global positioning system trackers by her perpetrator. The gastroenterology team performed an upper endoscopy and retrieved 2 global positioning system devices from her antrum. Most of these victims do not disclose any history of abuse because of fear of their perpetrators. Further training and research can help to allow for recognition of these victims and potentially help them...

Several studies have indicated that Camitz transfer for severe carpal tunnel does not adequately restore thumb opposition. The aim of this study was to determine whether modification of the distal insertion of the transferred palmaris longus tendon could provide more effective opposition. We used 12 fresh-frozen upper extremity specimens. For spatial analysis, we used a three-dimensional motion-tracking device. At 0 N and 5 N of traction force, the pronation angle was significantly larger for the modified procedure than for the conventional procedure...

BACKGROUND: For patients with cystic fibrosis (CF), sustaining lung function through the adolescent years is crucial to slow the progressive decline that leads to significant morbidity and early mortality. This holds true for patients with high per cent predicted forced expiratory volume in 1 s (ppFEV1 ), as they may receive less vigilant monitoring and treatment. Early identification of lung function decline followed by aggressive treatment can lead to preservation of lung function. INTERVENTION: The Emory+Children's Pediatric Cystic Fibrosis Program implemented multiple quality improvement (QI) initiatives to identify and aggressively treat adolescent patients with a rapid decline in lung function...

BACKGROUND: Articular cartilage structure and chondrocyte health are sensitive and reliant on dynamic joint loading during activities. The purpose of this pilot study was to determine the association between measures of individual and cumulative knee joint loading with T2 relaxation times in the knee cartilage of young individuals without knee injury. METHODS: Twelve participants (17-30 years old) without history of knee injury or surgery completed MRI, physical activity (PA), and biomechanical gait testing...

INTRODUCTION: Girl child, early and forced marriage (CEFM) persists in South Asia, with long-term consequences for girls. CARE's Tipping Point Initiative (TPI) addresses the causes of CEFM by challenging repressive gender norms and inequalities. The TPI engages different participant groups on programmatic topics and supports community dialogue to build girls' agency, shift inequitable power relations, and change community norms sustaining CEFM. METHODS/ANALYSIS: The Nepal TPI impact evaluation has an integrated, mixed-methods design...

Force multipliers are attributes of an organization that enable the successful completion of multiple essential missions. Core facilities play a critical role in the research enterprise and can be organized as force multipliers. Conceiving of cores in this way influences their organization, funding, and research impact. To function as a force multiplier for the research enterprise, core facilities need to do more than efficiently provide services for investigators and generate revenue to recover their service costs: they must be aligned with the strategic objectives of a research university...

BACKGROUND: Pedicle screw loosening is a major complication following spinal fixation associated with osteoporosis in elderly. However, denosumab is a promising treatment in patients with osteoporosis. The effect of denosumab on pedicle screw fixation is unknown. Therefore, we investigated whether denosumab treatment improves pedicle screw fixation in elderly patients with osteoporosis. METHODS: This was a 2-year prospective open-label study. From February 2015 to January 2016, we included 21 patients with postmenopausal osteoporosis who received initial denosumab treatment...

The conception of core facilities at a research university influences their organization, funding, and research impact. At Emory University, we conceive of core facilities as 'Force Multipliers.' This concept, derived from my experience as a US Navy surface warfare officer, implies that the most valuable attributes of an organization are those which enable successful completion of multiple missions. In the case of core facilities, we imagine that they should not only efficiently provide services for investigators, but they should also aid in the recruitment and retention of faculty, help acquire and maintain cutting-edge research platforms, and promote interaction and collaboration...

Noscapine is a phthalide isoquinoline alkaloid that easily traverses the blood brain barrier and has been used for years as an antitussive agent with high safety. Despite binding opioid receptors, noscapine lacks significant hypnotic and euphoric effects rendering it safe in terms of addictive potential. In 1954, Hans Lettré first described noscapine as a mitotic poison. The drug was later tested for cancer treatment in the early 1960's, yet no effect was observed likely as a result of its short biological half-life and limited water solubility...

After a distinguished career as a professor at Emory University and San Diego State University, this left-handed author-whose mother was also a southpaw-examines left-handedness in the context of studies that have contested the classifications and meanings of disability, forcing researchers to re-examine their assumptions and attitudes about disability while challenging public policies aimed at them .

Objective: It is hypothesized earlier non-invasive (NIV) ventilation benefits Amyotrophic Lateral Sclerosis (ALS) patients. NIV typically consists of the removable bi-level positive airway pressure (Bi-PAP) for adjunctive respiratory support and/or the cough assist intervention for secretion clearance. Historical international standards and current USA insurance standards often delay NIV until percent predicted forced vital capacity (FVC %predict) is <50. We identify the optimal point for Bi-PAP initiation and the synergistic benefit of daily Bi-PAP and cough assist on associative increases in survival duration...

A bio-inspired, slotted delta wing was abstracted from a multi-vane propulsor geometry ubiquitous in nature, and analysed to investigate aerodynamic performance during acceleratory and steady-state motions. Evolutionary convergence of slotted geometries in nature suggests an aerodynamic benefit in manoeuvrability, as exemplified in the fins and wings of a broad range of extant and extinct swimmers and flyers, respectively. Through direct force measurements and stereoscopic particle image velocimetry, it was found that the abstracted, slotted geometry exhibited a region of steady-state lift and drag enhancement at angles of attack greater than 25° when compared to a reference profile based on a delta-wing plate...

BACKGROUND: Development of goiter and hypothyroidism has been reported in patients with cystic fibrosis (CF) since the 1970s, especially when treated with iodine-based expectorants. With iodine-containing expectorants no longer in routine use, the prevalence of thyroid dysfunction in CF patients is unknown. This cross-sectional study assessed thyroid function status in a large cohort of CF patients. METHODS: Sera from ambulatory subjects were obtained from an Institutional Review Board (IRB)-approved biorepository of patients seen at the Emory CF Center between January 1, 2011, and December 31, 2014...

China is the epicenter of the global tobacco epidemic. China grows more tobacco, produces more cigarettes, makes more profits from tobacco and has more smokers than any other nation in the world. Approximately one million smokers in China die annually from diseases caused by smoking, and this estimate is expected to reach over two million by 2020. China cities have a unique opportunity and role to play in leading the tobacco control charge from the "bottom up". The Emory Global Health Institute-China Tobacco Control Partnership supported 17 cities to establish tobacco control programs aimed at changing social norms for tobacco use...

Amyotrophic lateral sclerosis is a disease with highly variable clinical features and prognosis. We analyzed the prognostic indicators of age, sex, bulbar or spinal onset, body mass index (BMI), and forced vital capacity (FVC) for 728 deceased patients from the Emory ALS Clinic. The median overall survival was 29.8 months from symptom onset, 15.8 months from diagnosis, and 14.3 months from the initial clinic visit. While univariate analyses revealed that each of the identified clinical features was strongly associated with patient survival, in multivariable analyses only age, BMI, and FVC measured at the first clinic visit were independent prognostic indicators; bulbar onset and sex were not significantly associated with survival prognosis after adjustment for the other clinical features...

BACKGROUND: Different modalities are used to diagnose interstitial lung disease. We compared the effectiveness of minimally invasive surgical biopsy versus high-resolution computed tomography for the diagnosis of interstitial lung disease and report the mortality of the procedure. METHODS: We reviewed 194 patients undergoing video-assisted thoracoscopic lung biopsies for the suspicion of interstitial lung disease from January 2003 to February 2012 at Emory University...

BACKGROUND: Optimizing treatment strategies to risk profile patients undergoing aortic valve replacement remains a priority. The role that specific and combinations of preoperative organ dysfunction (OD) plays in informing these decisions remains uncertain. This study sought to determine the relative effect that OD in particular systems has on short- and long-term outcomes. METHODS: A total of 1,759 aortic valve replacement cases with and without coronary artery bypass grafting performed from January 2002 to June 2010 at Emory University are the basis for this retrospective analysis...

Smad family proteins are essential intracellular mediators that regulate transforming growth factor-β (TGF-β) ligand signaling. In response to diverse stimuli, Smad7 is rapidly expressed and acts as a cytoplasmic inhibitor that selectively interferes with signals elicited from TGF-β family receptors. In addition, earlier works have indicated that retrovirally transduced Smad7 induces long-lasting cell proliferation arrest in a variety of mesenchymal cells through down-regulation of G1 cyclins. However, the molecular mechanisms underlying the cytostatic effects of Smad7 remain unknown...
