One cysticercus from the proper temporalis muscle: scenario record of a unusual way of display involving cysticercosis.
Conclusion  Total cfDNA may play a role as a biochemical marker of PE, compared with fetal cfDNA. Large prospective studies with homogeneous populations and standardized methodology are needed to further confirm its predictive value.There are no program evaluation approaches designed for a crisis, such as the COVID-19 pandemic. It is critical to evaluate the educational impact of COVID-19 to keep administrators informed and guide decision-making. The authors used systems thinking to design an evaluation model. The evaluation results suggest complex interactions between individuals and course level changes due to COVID-19. Specifically, year 1-2 students found more education metrics lacking relative to year 3-4 students, faculty, and course directors. There was no consensus for the value of similar instructional/assessment adaptations. The evaluation model can be adapted by other medical schools to fit systems-based needs.This paper proposes a new dimension reduction algorithm based on low-dimension ordered orthogonal projection (LOOP), which is used for cancer detection with terahertz (THz) images of freshly excised human breast cancer tissues. A THz image can be represented by a data cube with each pixel containing a high dimension spectrum vector covering several THz frequencies, where each frequency represents a different dimension in the vector. The proposed algorithm projects the high-dimension spectrum vector of each pixel within the THz image into a low-dimension subspace that contains the majority of the unique features embedded in the image. The low-dimension subspace is constructed by sequentially identifying its orthonormal basis vectors, such that each newly chosen basis vector represents the most unique information not contained by existing basis vectors. A multivariate Gaussian mixture model is used to represent the statistical distributions of the low-dimension feature vectors obtained from the proposed dimension reduction algorithm. The model parameters are iteratively learned by using unsupervised learning methods such as Markov chain Monte Carlo or expectation maximization, and the results are used to classify the various regions within a tumor sample. Experiment results demonstrate that the proposed method achieves apparent performance improvement in human breast cancer tissue over existing approaches such as one-dimension Markov chain Monte Carlo. read more The results confirm that the dimension reduction algorithm presented in this paper is a promising technique for breast cancer detection with THz images, and the classification results present a good correlation with respect to the histopathology results of the analyzed samples.
The aim of this retrospective study was to evaluate the outcomes of older patients with 2-part proximal humerus fractures (PHFs) with medial column disruption stabilized using a proximal humeral internal locking system (PHILOS) plate plus oblique insertion of autologous fibula as a primary procedure.

Data involving 112 patients (112 shoulders) sustaining 2-part PHFs with medial column disruption treated with PHILOS plate plus oblique insertion of autologous fibula as a primary procedure during 2012-2019 were identified. The median follow-up was 36 months (range 11.2-43.5 months). The primary endpoint was the Constant scores and American Shoulder and Elbow Surgeons (ASES) scores. The secondary endpoint was the main orthopedic complication rate.

The median Constant and ASES scores were 78 (range, 52-95) and 77 (range, 62-96) at the final follow-up, respectively. The main orthopedic complication rate was 10.7% (12/112). Twelve orthopedic complications in 8 patients were detected, and they involved loss of reduction, varus collapse, aseptic loosening, mal-union, revision, and intolerable shoulder pain. Of these complications, 3 (2.6%) involved loss of reduction, 2 (1.7%) involved varus collapse, 3 (2.6%) involved aseptic loosening, 1 (0.8%) involved mal-union, 2 (1.7%) required revision surgery, and 1 (0.8%) presented intolerable shoulder pain.

PHILOS plate plus oblique insertion of autologous fibula as a primary procedure may yield good functional outcomes and a low rate of the main orthopedic complications.

Geriatric-orthopaedic co-management models can improve patient outcomes. However, prior reports have been at large academic centers with "closed" systems and an inpatient geriatric service. Here we describe a Geriatric Fracture Program (GFP) in a mixed practice "pluralistic" environment that includes employed academic faculty, private practice physicians, and multiple private hospitalist groups. We hypothesized GFP enrollment would reduce length of stay (LOS), time to surgery (TTS), and total hospital costs compared to non-GFP patients.

A multidisciplinary team was created around a geriatric Nurse Practitioner (NP) and consulting geriatrician. Standardized geriatric focused training programs and electronic tools were developed based on best practice guidelines. Fracture patients >65 years old were prospectively enrolled from July 2018- June 2019. A trained biostatistician performed all statistical analyses. A p < 0.05 was considered significant.

With close multidisciplinary team work, a successful geriatric-orthopaedic comanagement model for geriatric fractures can be implemented in even a mixed practice environment without an inpatient geriatrics service.The coronavirus disease 2019 (COVID-19) pandemic is challenging the current public health emergency response systems (PHERSs) of many countries. Although environmental factors, such as those influencing the survival of viruses and their transmission between species including humans, play important roles in PHERSs, little attention has been given to these factors. This study describes and elucidates the roles of environmental factors in future PHERSs. To improve countries' capability to respond to public health emergencies associated with viral infections such as the COVID-19 pandemic, a number of environmental factors should be considered before, during, and after the responses to such emergencies. More specifically, to prevent pandemic outbreaks, we should strengthen environmental and wildlife protection, conduct detailed viral surveillance in animals and hotspots, and improve early-warning systems. During the pandemic, we must study the impacts of environmental factors on viral behaviors, develop control measures to minimize secondary environmental risks, and conduct timely assessments of viral risks and secondary environmental effects with a view to reducing the impacts of the pandemic on human health and on ecosystems.
