RESUMEN

Population-level surveillance of student weight status (particularly monitoring students with a body mass index (BMI) ≥95th percentile) remains of public health interest. However, there is mounting concern about objectively measuring student BMI in schools. Using data from the nation's largest school district, we determined how closely students' self-reported BMI approximates objectively-measured BMI, aggregated at the school level, to inform decision-making related to school BMI measurement practices. Using non-matched data from n = 82,543 students with objective height/weight data and n = 7676 with self-reported height/weight from 84 New York City high schools (88% non-white and 75% free or reduced-price meal-eligible enrollment), we compared school-level mean differences in height, weight, BMI, and proportion of students by weight status, between objective and self-reported measures. At the school-level, the self-reported measurement significantly underestimated weight (-1.38 kg; 95% CI: -1.999, -0.758) and BMI (-0.38 kg/m2; 95% CI: -0.574, -0.183) compared to the objective measurement. Based on the objective measurement, 12.1% of students were classified as having obesity and 6.3% as having severe obesity (per CDC definition); the self-report data yielded 2.5 (95% CI: -1.964, -0.174) and 1.4 (95% CI: -2.176, -0.595) percentage point underestimates in students with obesity and severe obesity, respectively. This translates to 13% of students with obesity and 21% of students with severe obesity being misclassified if using self-reported BMI. School-level high school students' self-reported data underestimate the prevalence of students with obesity and severe obesity and is particularly poor at identifying highest-risk students based on BMI percentile.

RESUMEN

BACKGROUND: Our objective was to evaluate in patients with prosthetic valve endocarditis (PVE) treated conservatively, the prognostic value of white blood cell (WBC) signal intensity on SPECT and to describe the evolution of the WBC signal under antibiotics. METHODS: Patients with PVE treated conservatively and positive WBC-SPECT imaging were identified retrospectively. Signal intensity was classified as intense if equal to or higher, or mild if lower, than the liver signal. Clinical, biological, imaging and follow-up information were collected from medical files. RESULTS: Among 47 patients, WBC signal was classified as intense in 10 patients and as mild, in 37. The incidence of the primary composite endpoint (death, late cardiac surgery, or relapse) was significantly higher in patients with intense vs. mild signal (90% vs. 11%). Twenty-five patients underwent a second WBC-SPECT imaging during follow-up. The prevalence of WBC signal decreased progressively from 89% between 3 and 6 weeks to 42% between 6 and 9 weeks and 8% more than 9 weeks after initiation of antibiotics. CONCLUSIONS: In patients with PVE treated conservatively, intense WBC signal was associated with poor outcome. WBC-SPECT imaging appears as an interesting tool for risk stratification and to monitor locally the efficacy of antibiotic treatment.

RESUMEN

The purpose of this clinical report was to describe the use of a piezographic impression associated with computer-aided design and computer-aided manufacturing (CAD-CAM) for teeth setup and of digital tools for neuro-musculo-kinetic analyses. An edentulous patient with hemiglossectomy and heavily resorbed mandible consulted for complete denture rehabilitation to improve their masticatory function and speech. Master casts, wax rims, and piezographic impression were scanned for digital prosthetic work. Two digital try-ins were performed to respect the neutral zone: try-in 1 with posterior crossbite and try-in 2 without crossbite. Muscle activity and mandibular kinetics were performed for each try-in following the MAC2 protocol (six criteria): muscular tone, contraction synchrony, contraction efficiency, interocclusal rest distance, amplitude of mandibular movement, and velocity. Try-in 2 showed better data than try-in 1 in all criteria: muscle tone (respectively 71% vs. 59%), contraction synchrony (79% vs. 75%), contraction efficiency (85% vs. 77%), an increase in range of motion of 3.3 mm, and a better velocity (0.35 ± 0.12 s vs. 0.57 ± 0.14 s, p = 0.008). The piezographic impression, in combination with CAD-CAM, allowed the comparison of two prosthetic designs and the selection of the try-in with the best neuro-musculo-kinetic results.

RESUMEN

AIM: The objective of this study was to evaluate the diagnostic performance of white blood cells (WBC)-SPECT imaging in patients with suspicion of prosthetic valve endocarditis (PVE) against intra-operative findings. METHODS: 36 consecutive patients who underwent cardiac surgery 30 days after WBC-SPECT imaging were identified retrospectively. Clinical, imaging, and biological results were collected from reports. WBC-SPECT results were classified as positive or negative and, if positive, the intensity of signal graded as intense or mild. Lesions observed during cardiac surgery were collected from surgeons' reports. RESULTS: The 20 patients with positive WBC-SPECT study had confirmed PVE intra-operatively. Patients with intense signal on WBC-SPECT had high prevalence of abscesses (83%) compared to patients with only mild signal (12%). The three patients with negative WBC-SPECT but confirmed PVE had longer duration of antibiotic treatment before imaging and had no perivalvular abscess. Sensitivity, specificity, positive predictive and negative values, and accuracy of WBC-SPECT were measured at 87%, 100%, 100%, 81%, and 92%, respectively. Addition of WBC-SPECT results to the modified Duke score helped re-classify correctly 25% of patients from possible to definite PVE. CONCLUSION: In patients with suspicion of PVE, WBC-SPECT imaging provides excellent diagnostic performance against intra-operative findings.

RESUMEN

OBJECTIVES: To evaluate the causes and predictors of mortality after valve-in-mitral annulus calcification (MAC) transcatheter mitral valve implantation (TMVI). BACKGROUND: Conventional surgical mitral valve replacement is associated with a high risk in patients with mitral valve disease associated with severe MAC. In this population, TMVI may be an attractive alternative option. However, its prognostic factors are poorly understood. METHODS: All patients undergoing valve-in-MAC TMVI from 2013 to 2018 in our center were included. Indication for TMVI relied on the judgment of the local heart team. Patients were followed at 30 days and 1 year. RESULTS: A total of 34 patients underwent valve-in-MAC TMVI. The mean age was 79 ± 11 years and 73% of patients were women. Their mean EuroSCORE 2 was 8 ± 7%. The transseptal approach was used in 79% of patients and a hybrid transatrial in 29%. Balloon expandable transcatheter heart valves were used in all the patients. Technical success was achieved in 76% of the patients. Thirty-day and 1-year all-cause mortality rates were 14.7% and 32.4%, respectively. The main two causes of 1-year mortality were congestive heart failure (8.8%) and infective endocarditis (5.9%). In multivariate analysis, the only predictor of 1-year mortality was the presence of periprothetic mitral regurgitation grade 2 (HR, 5.69; 95%CI, 1.59-27.88, p = 0.032). CONCLUSION: Early and mid-term mortality remains high after valve-in-MAC TMVI and seems to be associated with the presence of paravalvular mitral regurgitation. However, whether the latter is a prognostic factor or marker remains to be determined to improve clinical outcomes in this high-risk population.

RESUMEN

The prevalence of arterial hypertension in mitochondrial diseases remains unknown. Between January 2000 and May 2014, we retrospectively included patients with genetically proven mitochondrial diseases. We recorded clinical, genetic and cardiac exploration data, including the measure of arterial pressure. Among the 260 patients included in the study (mean age = 44 ± 15 years, women = 158), 108 (41.5%) presented with arterial hypertension. The prevalence of hypertension by sex and age was higher than that observed in the general population for all groups. The prevalence of hypertension was significantly higher in patients with MELAS (mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes) mutations (66%) and MERRF (myoclonus, epilepsy, ataxia with ragged ref fibres) mutations (61%). In patients with MELAS mutation, the presence of hypertension was significantly associated with age and mutation rate in the blood (odds ratio = 1.12; P = .02) in multivariate analysis. The prevalence of hypertension was more important in patients having a mitochondrial disease. The increased risk was more important in patient with MELAS or MERRF and depended on the rate of heteroplasmy.

RESUMEN

Objectives: Financial exploitation (FE) in old age is poorly understood, particularly among those without significant cognitive impairment. The Finance, Cognition, and Health in Elders Study (FINCHES) aims to identify factors associated with FE among cognitively-healthy older adults. Preliminary findings regarding physical and mental health correlates in the pilot phase of FINCHES are reported.Method: Sixteen older adults who self-reported FE were demographically-matched on age, education, sex, and race/ethnicity to eighteen older adults who did not report past FE.Results: Those who believed they were exploited endorsed significantly greater symptoms of depression (p = 0.014) and marginally greater symptoms of anxiety (p = 0.062). Participants trended towards lower perceived successful aging (p = 0.094). Perceived FE participants also endorsed greater medical conditions (p = 0.047), but follow-up individual item analyses suggest that this was driven by problems with sleep (p = 0.030).Conclusions: These preliminary findings from the pilot phase of FINCHES highlight negative mental health factors associated with perceived FE among cognitively-intact older adults.

RESUMEN

Fibular free flap reconstruction remains the workhorse of postmandibulectomy reconstruction. Dental implantation to support a dental prosthesis is a sought-after outcome when the area of resection involves tooth-bearing zones. Chronic perisoft tissue pedicle hyperplasia with secondary infection leading to gradual bone loss is a simple complication to manage in the general population, but it becomes a serious issue in the fibula mandibular reconstruction patient in that it can lead to pathological fracture of the fibula. A case of a patient with a near fracture of his fibula mandibular reconstruction, and its management via a minimally invasive approach is presented.

RESUMEN

An appropriate presentation of maxillofacial defects and their prosthetic rehabilitation concepts using traditional two-dimensional educational materials is challenging for dental students and prosthodontics residents. This technique article introduces a simple approach to visualize and communicate three-dimensional (3D) virtual models embedded into a portable document format (PDF) file for presenting maxillofacial prosthetics concepts and enhancing students' spatial ability when learning maxillofacial prosthetics. MeVisLab software was used to combine various maxillofacial models and save them as a single 3D model. Adobe Acrobat Pro DC software was used to import the 3D model and create interactive visualization PDF documents. Adobe reader software was then used to visualize the content of the PDF documents. This approach allows educators to develop PDF files with multiple 3D models for teaching maxillofacial prosthetics concepts and communicate them with their students. Students can simply open the PDF file, activate the 3D mode, and interactively manipulate the 3D models to enhance their spatial ability for learning maxillofacial prosthetics.

RESUMEN

This technique article describes an approach to managing excessive gingival display by lengthening of the clinical crowns using a digital workflow. An intraoral scanner was used to obtain a template to be used for the crown lengthening surgical procedure considering the patient-desired diagnostic setups while fully seating the template on the patient's teeth during surgery. Using a digital approach for lengthening the clinical crowns decreased the likelihood of the need for postsurgical modifications, thus shortening the treatment duration. After the crown lengthening healed for 12 weeks, full-mouth reconstruction proceeded. Maxillary and mandibular preparation reduction guides were digitally designed and printed to facilitate conservative crown preparations. An intraoral scanner was used to make full-arch scans and interocclusal records for the fabrication of provisional and final crowns. Fully guided implant planning and placement were also executed.

RESUMEN

Some shifts in the gut microbiota composition and its metabolic fingerprints have been associated to Sleeve gastrectomy (SG) and Roux-en-Y Gastric Bypass (RYGB). So far, plasma bile acids have been associated with post-operative glucose improvement and weight loss, but nothing is known about their metabolism in the gut lumen. As bile acids are physiologically transformed by the microbiota into various species, the aim of this work was to study how SG and RYGB-associated dysbiosis impact the bioconversion of bile acids in the intestinal lumen. Comparing SHAM (n = 9) with our validated rat models of SG (n = 5) and RYGB (n = 6), we quantified luminal bile acids along the gut and found that the metabolic transformation of bile acids (deconjugation, dehydroxylation, and epimerization) is not different from the duodenum to the colon. However, in the cecum where the biotransformation mainly takes place, we observed deep alterations of the microbiota composition, which were specific of each type of surgery. In conclusion, despite specific dysbiosis after surgery, the bile acids metabolism in the gut lumen is highly preserved, suggesting that a resilience of the gut microbiota occurs after these procedures.

RESUMEN

Postpartum thyroiditis (PPT) is an autoimmune-mediated destructive thyroiditis that occurs in the first year postpartum with a prevalence of 5%. In order to appropriately counsel and treat the patient, physicians need to recognize the signs and symptoms of PPT and distinguish PPT from Graves hyperthyroidism. This review of PPT will discuss the etiology, clinical course, risk factors, prognosis, and treatment of PPT. Understanding PPT is important for all physicians taking care of women in the peripartum period as women who have had PPT are at an increased risk of subsequent episodes of PP and at risk of permanent hypothyroidism.

RESUMEN

PURPOSE: Radiotherapy is one of the main treatment modalities for head and neck cancers. To minimize damage to normal tissues during radiotherapy, various methods of stabilization have been used, including thermoplastic facemasks and repositioning stents. The goal is to assess the effect of using a customized oral repositioning stent on patient positioning during the course of radiotherapy. MATERIALS AND METHODS: Ten consecutive patients scheduled to undergo intensity modulated radiation therapy (IMRT) for cancers of the maxillary sinus, nasal cavity, or oral cavity were recruited to participate in the study (ST group). These patients were matched to 2 retrospective cohorts, one using the original repositioning stent design (OB group), and the other with no stabilization stent (NB group). Hard baseplate wax was used to create a customized wax pattern of the proposed acrylic stent chairside, and processed in heat-cured clear hard acrylic. Relative stability of the daily patient setup was assessed by comparing measurements from surrogate bony landmarks to radiation isocentres obtained from the initial reconstructed planning computed tomograph (CT) to each daily KeV image. RESULTS: There was no stent fracture or distortion throughout treatments, and no patients' treatments were required to be aborted, delayed, or replanned. Mean 3D deviations for the ST, OB, and NB groups were 0.29 ± 0.10 cm, 0.32 ± 0.14 cm, and 0.31 ± 0.13 cm, respectively. The ANOVA test revealed no significant difference in triangulated variations between the treatment groups (F = 0.18, p = 0.84). Patient stability data demonstrated mean vertical, longitudinal, and lateral variations that did not appear different when compared to 2 retrospective cohorts. Although the deviations were not statistically significant between matched cohorts, the added durability of the stent and comfort for patients, without affecting IMRT timeline, are considered clinically significant. CONCLUSION: By using a customized repositioning stent, it is possible to maintain patient stability comparable to prior protocols and within the range of clinical guidelines, while providing superior comfort and ease of insertion to the patients.

RESUMEN

Prosthodontic rehabilitation of a congenital or acquired defect of the ear is considered a challenging and skill-dependent procedure. This technical report describes a novel approach for direct digital scanning of the unaffected contralateral ear using an intraoral scanner and external markers. The obtained digital data of the ear was exported, digitally mirrored, and successfully positioned to a virtual model of a human head with a missing ear. This technique demonstrates the potential application of CAD/CAM in the design and fabrication of an auricular prosthesis for patients with a unilateral ear defect.

RESUMEN

STATEMENT OF PROBLEM: Dental implants can be essential in the rehabilitation of various cancer defects, but their ideal placement can be complicated by the limited dimensions of the available host bone. Surgical interventions developed to increase the amount of bone are not all predictable or successful and can sometimes be contraindicated. Short dental implants have been suggested as an alternative option in sites where longer implants are not possible. Whether they provide a successful treatment option is unclear. PURPOSE: The purpose of this study was to review the literature on short dental implants and assess whether they are a viable definitive treatment option for rehabilitating cancer patients with deficient bone. MATERIAL AND METHODS: A scoping review of the literature was performed, including a search of established periodontal textbooks for articles on short dental implants combined with a search of PubMed, MEDLINE, EMBASE, Web of Science, and Cochrane Database of Systematic Reviews. A search for all literature published before June 2016 was based on the following keywords: ['dental implants' OR 'dental implantation, endosseous' OR 'dental prosthesis, implant supported'] AND [short]. RESULTS: The minimum acceptable implant length has been considered to be 6 mm. The survival rates of short implants varied between 74% and 96% at 5 years, depending on factors such as the quality of the patient's bone, primary stability of the implant, clinician's learning curve, and implant surface. Short implants can achieve results similar to those of longer implants in augmented bone and offer a treatment alternative that could reduce the need for invasive surgery and associated morbidity and be safer and more economical. CONCLUSIONS: Short dental implants (6 mm to 8 mm) can be used successfully to support single or multiple fixed reconstructions or overdentures in atrophic maxillae and mandibles. The use of short dental implants lessens the need for advanced and complicated surgical bone augmentation procedures, which reduces complications, costs, treatment time, and morbidity. Short implants could be an alternative in the rehabilitation of patients with cancer.

RESUMEN

The development of methods for in vivo detection of cerebral beta amyloid retention and tau accumulation have been increasingly useful in characterizing preclinical Alzheimer's disease (AD). While the association between these biomarkers and eventual AD has been demonstrated among cognitively intact older adults, the link between biomarkers and neurocognitive ability remains unclear. We conducted a meta-analysis to test the hypothesis that cognitively intact older adults would show statistically discernable differences in neuropsychological performance by amyloid status (amyloid negative = A-, amyloid positive = A+). We secondarily hypothesized a third group characterized by either CSF tau pathology or neurodegeneration, in addition to amyloidosis (A+/N+ or Stage 2), would show lower neuropsychology scores than the amyloid positive group (A+/N- or Stage 1) when compared to the amyloid negative group. Pubmed, PsychINFO, and other sources were searched for relevant articles, yielding 775 total sources. After review for inclusion/exclusion criteria, duplicates, and risk of bias, 61 studies were utilized in the final meta-analysis. Results showed A+ was associated with poorer performance in the domains of global cognitive function, memory, language, visuospatial ability, processing speed, and attention/working memory/executive functions when compared to A-. A+/N+ showed lower performances on memory measures when compared to A+/N- in secondary analyses based on a smaller subset of studies. Results support the notion that neuropsychological measures are sensitive to different stages of preclinical AD among cognitively intact older adults. Further research is needed to determine what constitutes meaningful differences in neuropsychological performance among cognitively intact older adults.

RESUMEN

STATEMENT OF PROBLEM: The value of digital panoramic radiographs to screen for problems before fabricating conventional complete dentures is unclear. PURPOSE: The purpose of this retrospective study was to examine the influence of pretreatment digital panoramic radiographs on the clinical management of patients receiving complete removable dental prostheses. MATERIAL AND METHODS: The clinical records, including panoramic radiographs, of 169 patients seeking new complete removable dental prostheses over a 6-year period were interpreted independently by both a prosthodontist and an oral and maxillofacial radiologist to identify radiographic findings that influenced clinical patient management. A 95% confidence interval and an observed proportion of agreement were used to interpret the results. RESULTS: Sixty percent of the 169 radiographs examined had 1 or more abnormal or positive radiographic findings; however, only 6 (<4%) of 165 abnormalities detected influenced patient management, and 3 of them were identified during the clinical examination. CONCLUSIONS: Pretreatment digital panoramic radiographs revealed very few abnormalities that influenced the treatment of patients requiring complete removable dental prostheses. Furthermore, the digital images in this study revealed positive findings at a rate similar to those found in studies assessing analog radiographs, reinforcing current guidelines that recommend against radiographic screening of patients who seek new complete removable dental prostheses.

RESUMEN

BACKGROUND: The majority of transcatheter aortic valve implantation (TAVI) procedures are currently performed by percutaneous transfemoral approach. The potential contribution of the type of vascular closure device to the incidence of vascular complications is not clear. AIM: To compare the efficacy of a Prostar XL- vs. Perclose ProGlide-based vascular closure strategy. METHODS: The ClOsure device iN TRansfemoral aOrtic vaLve implantation (CONTROL) multi-center study included 3138 consecutive percutaneous transfemoral TAVI patients, categorized according to vascular closure strategy: Prostar XL- (Prostar group) vs. Perclose ProGlide-based vascular closure strategy (ProGlide group). Propensity-score matching was used to assemble a cohort of patients with similar baseline characteristics. RESULTS: Propensity matching identified 944 well-matched patients (472 patient pairs). Composite primary end point of major vascular complications or in-hospital mortality occurred more frequently in Prostar group when compared with ProGlide group (9.5 vs. 5.1%, P = 0.016), and was driven by higher rates of major vascular complication (7.4 vs. 1.9%, P < 0.001) in the Prostar group. However, in-hospital mortality was similar between groups (4.9 vs. 3.5%, P = 0.2). Femoral artery stenosis occurred less frequently in the Prostar group (3.4 vs. 0.5%, P = 0.004), but overall, Prostar use was associated with higher rates of major bleeding (16.7 vs. 3.2%, P < 0.001), acute kidney injury (17.6 vs. 4.4%, P < 0.001) and with longer hospital stay (median 6 vs. 5 days, P = 0.007). CONCLUSIONS: Prostar XL-based vascular closure in transfemoral TAVI procedures is associated with higher major vascular complication rates when compared with ProGlide; however, in-hospital mortality is similar with both devices.

RESUMEN

Gram-negative bacteria are normally resistant to the antibiotic vancomycin (VAN), which cannot significantly penetrate the outer membrane. We used Escherichia coli mutants that are partially sensitive to VAN to study synergies between VAN and 10 other antibiotics representing six different functional categories. We detected strong synergies with VAN and nitrofurantoin (NTR) and with VAN and trimethoprim (TMP) and moderate synergies with other drugs, such as aminoglycosides. These synergies are powerful enough to show the activity of VAN against wild-type E. coli at concentrations of VAN as low as 6.25 µg/ml. This suggests that a very small percentage of exogenous VAN does enter E. coli but normally has insignificant effects on growth inhibition or cell killing. We used the results of pairwise interactions with VAN and the other 10 antibiotics tested to place VAN into a functional category of its own, as previously defined by Yeh et al. (P. Yeh, A. I. Tschumi, and R. Kishony, Nat Genet 28:489-494, 2006, http://dx.doi.org/10.1038/ng1755).
