BACKGROUND: Template-guided implant placement is a method for optimal implant positioning from a prosthetic and surgical viewpoint. The treatment planning is based on three-dimensional X-ray data and model scan data, as well as on prosthetic planning (set-up). These data are matched (superimposed) with the aid of an X-ray template or by manual matching without special referencing. PURPOSE: The objective of this prospective controlled clinical study was to determine and compare the accuracy of the match with and without an additional X-ray template...

Lixuan Niu, Juan Wang, Huajie Yu, Lixin Qiu
BACKGROUND: It is complicated to select an appropriate sinus floor elevation and the procedure for sinus floor elevation lacks of consensus. Sinus contour plays an important role in choosing a surgery approach. But there are still no published articles revealing the influence of sinus contours to sinus floor elevation surgery. PURPOSE: We propose a new classification depending on sinus contours from cone-beam computed tomography (CBCT), analyze clinical characters of different types, and investigate the relationship between sinus contours and sinus floor elevation...

Conventional 3D printing technologies typically rely on open-loop, calibrate-then-print operation procedures. An alternative approach is adaptive 3D printing, which is a closed-loop method that combines real-time feedback control and direct ink writing of functional materials in order to fabricate devices on moving freeform surfaces. Here, it is demonstrated that the changes of states in the 3D printing workspace in terms of the geometries and motions of target surfaces can be perceived by an integrated robotic system aided by computer vision...

The role of experts and their presentation of testimony in insanity cases remain controversial. In order to decrease possible expert bias associated with this testimony, a number of different alternatives to adversarial presentation have been suggested. Two such alternatives are the use of court-appointed experts and the use of concurrent testimony (or "hot-tubbing"), in which opposing experts provide testimony concurrently and converse with each other directly. An experiment using a sample of venire jurors (n = 150) tested the effect of these alternatives...

Materials selection is a critical aspect for the production of scaffolds for osteochondral tissue engineering. Synthetic materials are the result of man-made operations and have been investigated for a variety of tissue engineering applications. Instead, the products of physiological processes and the metabolic activity of living organisms are identified as natural materials. Over the recent decades, a number of natural materials, namely, biopolymers and bioceramics, have been proposed as the main constituent of osteochondral scaffolds, but also as cell carriers and signaling molecules...

BACKGROUND: Total hip arthroplasty (THA) is a successful procedure to treat end-stage hip osteoarthritis. The procedure is increasingly performed in adults of working age, who often wish to return to sports (RTS) and return to work (RTW). However, a systematic overview of the evidence on RTS and RTW after THA is lacking. OBJECTIVES: Our aim was to systematically review (1) the extent to which patients RTS and RTW after THA, including (2) the time to RTS and RTW...

Chemical reactions and many of the procedures of separation and purification employed in industry, research or chemistry teaching utilize solvents massively. In the last decades, with the birth of Green Chemistry, concerns about the employment of solvents and the effects on human health, as well as its environmental impacts and its dependence on non-renewable raw materials for manufacturing most of them, has drawn the attention of the scientific community. In this work, we review the concept of green solvent and the properties and characteristics to be considered green...

Gold nanoparticles (AuNPs) were electrodeposited on the surface of a glassy carbon electrode (GCE) and then treated with a mixture of a thiolated DNA sequence (p-63; with high affinity for bisphenol A) and free bisphenol A (BPÀ). Pyrrole was then electropolymerizaed on the surface of the GCE to entrap the BPA@p-63 complex. BPA is then extracted with acetic acid solution to obtain MIP cavities where the embedded DNA sequence acts as the binding site for BPA. Scanning electron microscopy, electrochemical impedance spectroscopy, and cyclic voltammetry were employed to characterize the surface of the modified GCE...

BACKGROUND: The cytoreductive surgery (CRS) associated with hyperthermic intraperitoneal chemotherapy (HIPEC) has become the standard treatment in patients with carcinomatosis peritoneal from different origins. The use of a minimally invasive approach for this high complex procedure might be an alternative that provides them less morbidity and faster recovery with similar oncologic outcomes. METHODS: We describe the initial experience of CRS and HIPEC done via the laparoscopic route in patients with minimal peritoneal metastases in our Unit from March 2016 to January 2018...

Periprosthetic infections are hazardous complications. After dental procedures, an antibiotic prophylaxis or treatment is actually not recommended according to the current guidelines. In the present work, a case of a hematogenous late infection after primary total hip arthroplasty due to a prior dental procedure is presented. Hereby, the question evolves as to whether in selected cases an antibiotic prophylaxis or treatment might be indicated at the site of dental procedures.

BACKGROUND: One quarter of the global disease burden could be avoided with management strategies for environmental risk factors such as air and water pollution, food contamination, injuries and poor road safety. Many decisions influencing health are made outside the health sector; thus, the joint consideration and implementation of health and environmental factors in the relevant policies are becoming increasingly important. MATERIALS AND METHODS: By means of a selective literature search, we identified important policy documents and selected research articles as a basis for the introduction and current discussion of the Health in All Policies (HiAP) approach...
