Due to the highly predictable long-term clinical outcomes, modern implant dentistry has become one of the most preferred treatment modalities for restoring missing teeth. However, the complications of implant therapy compromise the long-term implant success and remain a great challenge to clinicians. Hardware complications include the mechanical complications which are related to the manufacturer-fabricated components of the prosthesis, such as abutment/screw loosening, fracture and implant fracture; and the technical complication which are related to laboratory-fabricated components of the prosthesis, such as veneer chipping. The biological complications mainly include peri-implant mucositis and peri-implantitis. It is crucial to figure out how to effectively avoid and manage the complications of implant therapy. https://www.selleckchem.com/products/blu-285.html This article reported the definitions, incidences, risk factors, prevention and treatment of both mechanical and biological complications of implant therapy.With the development of dental implant prosthodontic technique, many new concepts and methods have emerged. In the light of present situation, implant prosthodontic technique is developing towards precision, comfortability, immediacy and digitization. Meanwhile, the research area is focusing on expanding immediate restoration indications, clinical selection strategies of different prosthodontic materials and the accuracy of digitalized prosthodontics. The paper aims to discuss the developing trend in prosthodontics of dental implantology for clinical reference.Oral implantology has experienced more than half a century of development, the theoretical foundation and clinical technology are becoming more mature. This article elaborates on the establishment of implant timing, implant-related bone augmentation technology, surgical alternatives to bone augmentation technology, implant-related soft tissue augmentation technology, and computer-guided surgery. Provide a reference for a comprehensive understanding of dental implant surgery technology and its new developments.
Falling is one of the most common problems in older adults and can lead to additional health problems. This study aimed to determine the effects of a multicomponent program on fall incidence and quality of life in older adult nursing home residents.

This was a quasi-experimental study with a pretest and post-test design. The study population comprised 55 older adults residing in nursing homes. The intervention was a multicomponent program including physical activities, training sessions, and physical environment modifications in nursing homes that was conducted for 8 weeks. The data collection tools included a socio-demographic characteristics form and questionnaires pertaining to the quality of life and fear of falls, which were completed by the participants before and after the intervention.

The mean age of the participants was 68.48 years, and most (90%) were illiterate. We observed a significant difference between the mean number of falls and the scores for fear of falling before and after the intervention (p<0.001). We also observed a significant difference between the total quality of life scores and all of the related dimensions before and after the intervention, indicating that the quality of life of the older adults had improved after the intervention (p<0.001).

The results of this study indicated that the multicomponent fall prevention program was effective in improving the quality of life, fall rate, and fear of falling among older residents in nursing homes. Further studies are needed to explore the long-term effects of these interventions.

Despite several morphological and molecular studies, however, its evolutionary history and phylogeography remain poorly understood. Phayre's langur ( Trachypithecus phayrei) is one of the most widespread members of the genus, but details on its actual distribution and intraspecific taxonomy are limited and controversial. Thus, to elucidate the evolutionary history of Trachypithecus and to clarify the intraspecific taxonomy and distribution of T. phayrei, we sequenced 41 mitochondrial genomes from georeferenced fecal samples and museum specimens, including two holotypes. Phylogenetic analyses revealed a robustly supported phylogeny of Trachypithecus, suggesting that the T. pileatus group branched first, followed by the T. francoisi group, and the T. cristatus and T. obscurus groups most recently. The four species groups diverged from each other 4.5-3.1 million years ago (Ma), while speciation events within these groups occurred much more recently (1.6-0.3 Ma). Within T. phayrei, we found three clades that diverged 1.0-0.9 Ma, indicating the existence of three rather than two taxa. Following the phylogenetic species concept and based on genetic, morphological, and ecological differences, we elevate the T. phayrei subspecies to species level, describe a new species from central Myanmar, and refine the distribution of the three taxa. Overall, our study highlights the importance of museum specimens and provides new insights not only into the evolutionary history of T. phayrei but the entire Trachypithecus genus as well.
Foot and leg pain in complex regional pain syndrome (CRPS) presents a challenge even with neuromodulation techniques such as spinal cord stimulation (SCS). We report our experience with a novo technique of direct sciatic nerve electrical stimulation (DISNES) for intractable foot and leg pain in CRPS I.

Following Research Ethics Board (REB) approval, data were gathered for 16 patients (10 women and 6 men, age 26-61 years) who had been subjected to ipsilateral DISNES. All 16 patients had failed conventional medical management. As well, seven subjects were previously treated with SCS for CRPS I pain. These subjects reported pain relief in the thigh and leg, however the SCS was unable to alleviate the disabling foot pain despite varied and multiple programming techniques. The remaining nine subjects were treated primarily with DISNES. Evaluation was done using visual analog scale (VAS), Oswestry Disability Index version 2 (ODI), and quality of life (EQ-5D and SF-36) scores done both pre-DISNES and at two follow-ups.
