Introduction: Root canal treatment (RCT) plays an important role in preserving the dentition by deferring other invasive treatments. Data on tooth survival and predictive factors for tooth loss after RCT in the military cohort are lacking. This investigation aimed to determine the proportion of teeth surviving in an 8-year period after RCT and identify potential predictive factors for tooth loss in a UK military cohort.

Objective: To examine the association of hospital expenditure with continuing nurse education and staffing on improvements in nurse-sensitive, patient-safety outcomes.

Data Sources: Data obtained from 12-year (2007-2018) panel of Florida acute-care general hospitals.

Study Design: We assess the relationship of hospital expenditure on continuing nurse education and staffing on nurse-sensitive, patient-safety outcomes from the Agency for Healthcare Research and Quality: advanced-stage (stage 3 or 4) pressure injuries/ulcers, central venous catheter-related blood stream infection, and deep vein thrombosis.

Background: Fecal examinations in pet cats and dogs are key components of routine veterinary practice; however, their accuracy is influenced by diagnostic methodologies and the experience level of personnel performing the tests. The VETSCAN IMAGYST system was developed to provide simpler and easier fecal examinations which are less influenced by examiners' skills. This system consists of three components: a sample preparation device, an automated microscope scanner, and analysis software.

Implants used to replace molar teeth present issues of space distribution and crown contours that are unique to these sites. Because the diameter of the implant typically is smaller than that of the tooth being replaced, and the circular shape of the implant does not replicate the anatomy of the tooth, a large gingival embrasure area between the implant platform and adjacent tooth often results. Upon the review of radiographs of molar implants placed over an 11-year period in one private practice, the authors identified an unusually high incidence of approximal, cervical, and root caries on teeth adjacent to these implants.

Article Synopsis
  • Fecal examinations are essential for pet wellness, but their accuracy can vary based on sample preparation and the expertise of the person analyzing the results.
  • The VETSCAN IMAGYST system automates fecal analysis using advanced scanning and deep learning software to identify parasite eggs more efficiently compared to traditional methods.
  • Results showed that the VETSCAN IMAGYST's algorithm performed similarly to trained parasitologists, indicating high diagnostic reliability and potential advantages in ease of use and accuracy.

Intestinal protozoa are responsible for relatively few infections in the developed world, but the testing volume is disproportionately high. Manual light microscopy of stool remains the gold standard but can be insensitive, time-consuming, and difficult to maintain competency. Artificial intelligence and digital slide scanning show promise for revolutionizing the clinical parasitology laboratory by augmenting the detection of parasites and slide interpretation using a convolutional neural network (CNN) model.

The authors present an 11-year retrospective analysis of 300 immediately placed implants in molar extraction sockets. The protocol used for the placement and restoration of these implants is based upon a previously published article by the authors regarding the classification of molar extraction sockets. Four different implant systems were used during this study, and implants varied in diameter, length, and texture.

Dental implants may be successfully placed immediately into fresh extraction sockets when primary implant stability can be attained. This article presents a new classification system for molar extraction sites that describes extraction sockets based upon the bone available within the socket for stabilization of an immediately placed implant. Three categories--types A, B, and C--are employed: the type A socket, which allows for the implant to be placed completely within the septal bone, leaving no gaps between the implant and the socket walls; the type B socket, which has enough septal bone to stabilize but not completely surround the implant, leaving gaps between one or more surfaces of the implant and the socket walls; and the type C socket, which has little to no septal bone, thus requiring that the implant engage the periphery of the socket.

Objective: To understand factors associated with pediatric inpatient safety events, we test 2 hypotheses: (1) scarce resources (as measured by Medicaid burden) in safety-net hospitals relative to non-safety-net hospitals result in higher rates of safety events; and (2) higher levels of severity and more chronic conditions in patient populations lead to higher rates of safety events within hospital category and in children's hospitals in comparison with non-children's hospitals.

Methods: All nonnewborn pediatric hospital discharge records, which met criteria for potentially experiencing at least 1 pediatric quality indicator (PDI) event (using Agency for Healthcare Research and Quality's 2009 Nationwide Inpatient Sample and PDI) and weighted to represent national level estimates, were analyzed for patterns of PDI events within and across hospital categories by using bivariate comparisons and multivariable logit models with robust SEs. The outcome measure "ANY PDI" captures the number of pediatric discharges at the hospital level with 1 or more PDI event.

Objective: To assess the association between Medicaid-induced financial stress of a hospital and the probability of an adverse medical event for a pediatric discharge.

Data Sources: Secondary data from the Nationwide Inpatient Sample, Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project, and the American Hospital Association's Annual Survey of Hospitals. Study examines 985,896 pediatric discharges (children age 0-17), from 1,050 community hospitals in 26 states (representing 63 percent of the U.

A new approach to the replacement of four mandibular incisors with localized, chronic, severe periodontitis is proposed in this clinical report. Their replacement with immediately placed implants and a nonocclusally loaded provisional restoration is a simple, predictable, and successful treatment modality. Data from 10 consecutive clinical cases are presented, and a 100% implant survival rate is reported for a 6-year period of follow-up.

Objective: To examine the association of Medicaid market characteristics to potentially preventable adverse medical events for hospitalized children, controlling for patient- and hospital-level factors.

Data Sources/study Setting: Two carefully selected Agency for Healthcare Research and Quality (AHRQ) pediatric patient safety indicators (decubitus ulcers and laceration) are analyzed using the new pediatric-specific, risk-adjusting, patient safety algorithm from the AHRQ. All pediatric hospital discharges for patients age 0-17 in Florida, New York, and Wisconsin, and at risk of any of these two patient safety events, are examined for the years 1999-2001 (N=859,922).

Unlabelled: Clinicians are often confronted with changes in the anatomy of the local site following tooth extraction. Successful management of the extraction socket can be challenging, particularly in the aesthetic zone. Proper management is necessary to ensure that the implant used to support a prosthesis will remain stable.

We analyze Program Realignment, California's 1991 policy of decentralizing control of health, mental health, and social services, from the state to the counties. Drawing from the economics literature on intergovernmental transfers and using data constructed for this study, we analyze the impact of Realignment on uninsured health spending. We find a change in the pattern of spending on indigent health services by counties following decentralization.
