taking PrEP such as side effects which were cited in IDIs and FGDs. Key factors from FGDs include cost, fear of being outed, drug stockouts, fear of being known as MSMs by wives and lack of relevant information. FGDs cited stigma from health care workers, forgetfulness and community associated factors.

Despite having inadequate knowledge about PrEP, study participants were largely willing to use PrEP if available. Programs should include an effective information, education, and communication component around their preferences and provide PrEP in MSM-friendly sites.

The development of a successful coronavirus disease 2019 (COVID-19) control strategy requires a thorough understanding of the trends in the geographic and demographic distributions of the disease burden. In terms of the estimation of the population prevalence, this includes the crucial process of unravelling the number of patients who remain undiagnosed.

This study estimates the period prevalence of COVID-19 between March 1, 2020 and November 30, 2020 and the proportion of the infected population that remained undiagnosed for the provinces of Quebec, Ontario, Alberta, and British Columbia in Canada.

A model-based mathematical framework based on a disease progression and transmission model was developed to estimate the historical prevalence of COVID-19 using provincial-level statistics reporting seroprevalence, diagnoses, and deaths resulting from COVID-19. The framework was applied to three different age cohorts (under 30; 30-69; and 70+) in each of the provinces studied.

The estimates of COVID-19 period prevalence between March 1, 2020 to November 30, 2020 were 4.73% (4.42%-4.99%), 2.88% (2.75%-3.02%), 3.27% (2.72%-3.70%), 2.95% (2.77%-3.15%) for Quebec, Ontario, Alberta, and British Columbia, respectively. Among the cohorts considered in this study, the estimated total number of infections ranged from 2-fold the number of diagnoses (among Quebecers aged 70+ 26,476 diagnosed out of a total of 53,549) to 6-fold the number of diagnoses (among British Columbians aged 70+ 3,108 diagnosed out of a total of 18,147).

Our estimates indicated that a high proportion of the population infected between March 1 and November 30, 2020, remained undiagnosed. Knowledge of the COVID-19 period prevalence and undiagnosed population can provide vital evidence for policy makers to consider when planning COVID-19 control interventions and vaccination programs.

DNA origami can be applied as a "ruler" for nanoscale calibration or super-resolution fluorescence microscopy with an ideal structure for defining fluorophore arrangement, allowing the distance between fluorophores to be precisely controlled at the nanometer scale. DNA origami can also be used as a nanotag with arbitrary programmable shapes for topological identification. In this paper, we formed a hexagonal origami structure embedded with three different fluorescent dyes on the surface. The distance between each fluorescent block was ~120 nm, which is below the diffraction limit of light, allowing for its application as a nano-ruler for super-resolution fluorescence microscopy. The outside edge of the hexagonal structure was redesigned to form three different substructures as topological labels. Atomic and scanning force microscopy demonstrated consistency of the nanoscale distance between morphological and fluorescent labels. Therefore, this fluorophore-embedded hexagonal origami platform can be used as a dual nano-ruler for both optical and topological calibration.This work presents a large-scale three-fold annotated, low-cost microscopy image dataset of potato tubers for plant cell analysis in deep learning (DL) framework which has huge potential in the advancement of plant cell biology research. Indeed, low-cost microscopes coupled with new generation smartphones could open new aspects in DL-based microscopy image analysis, which offers several benefits including portability, easy to use, and maintenance. However, its successful implications demand properly annotated large number of diverse microscopy images, which has not been addressed properly- that confines the advanced image processing based plant cell research. Therefore, in this work, a low-cost microscopy image database of potato tuber cells having total 34,657 number of images, has been generated by Foldscope (costs around 1 USD) coupled with a smartphone. This dataset includes 13,369 unstained and 21,288 stained (safranin-o, toluidine blue-o, and lugol's iodine) images with three-fold annotation based on weight, section areas, and tissue zones of the tubers. The physical image quality (e.g., contrast, focus, geometrical attributes, etc.) and its applicability in the DL framework (CNN-based multi-class and multi-label classification) have been examined and results are compared with the traditional microscope image set. The results show that the dataset is highly compatible for the DL framework.Increasing the local concentration of microbubbles (MBs) within the blood flow plays a crucial role in several medical applications, but there are few imaging modalities available for volumetric tracking of the aggregated MBs in real time. Selleck Veliparib Here we describe a device integrating acoustic vortex tweezers (AVT) and ultrasound plane-wave imaging to achieve the goal of controlling the spatial distribution of MBs in blood vessels and simultaneously monitoring this process using the same probe. Experiments were conducted using a 5-MHz 2D array ultrasound probe (with three cycles of excitation at an acoustic pressure of 2000 kPa) and 1.2-μm-diameter MBs at a flow rate of 20 mm/s. The AVT waveform was produced by modulating the repetition frequency of the transmitted pulse asymmetrically (4 and 8 kHz at the inflow and outflow ends, respectively). In order to simultaneously capture MBs and perform imaging with the same probe, the asymmetric AVT pulse signal and the ultrasound-imaging pulse signal were arranged in a staggered series, and the imaging was performed using plane-wave pulses at nine angles (-7° to 7°) in compounded plane-wave imaging (volume rate 200 Hz). Microscopy observations showed that freely suspended MBs could indeed be gathered by the asymmetric AVT in the flow field to form an MBs cluster with a spot size of about 4022 μm2, which could resist the flow to remain at a fixed location for about 22 s. After the asymmetric AVT signal and the ultrasound-imaging pulse signal was turned on for 1 s, the ultrasound 3D image showed that the signal intensity of the MB clusters increased by 13.1±2.9 dB relative to the background area. These results show that the proposed strategy can be used to accumulate flowing MBs at a desired location and to simultaneously observe this phenomenon. This tool could be used in the future to improve the outcomes of MB-related treatments for various diseases.Tuberculosis (TB) is still a worldwide problem. We present a case of flexor tenosynovitis due to tuberculosis in the hand and wrist. A 42-year-old man presented to the outpatient clinic with a 2-year history of a slowly growing mass over the volar aspect of the left wrist. His MRI showed multiple rice bodies in the wrist and hand. An open biopsy was performed. Pathology specimens showed granulomatous lesions with central necrosis. The purified protein derivative (PPD) test was positive. In this case, granulomatous lesions with central necrosis, rice bodies, and positive PPD test confirmed the diagnosis of TB in the wrist and hand. There was no other concurrent evidence of TB elsewhere. Antituberculosis chemotherapy was commenced. Tuberculous tenosynovitis of the wrist and hand is very rare. The tuberculous tenosynovitis should be kept in mind as an infectious agent when patients are presenting with atypical clinical. Key words tuberculosis, rice bodies, flexor tenosynovitis, wrist, hand.In patients with defect bone growth and dwarfism, fractures of the weight bearing skeleton are relatively rare due to their reduced mobility. When they do occur, their treatment and potential surgery are complicated. The commonly used therapeutic procedures are not applicable, the available implants are not suitable, if a surgery is necessary. An individual approach and often times also improvisation is needed. It is important to realize that these patients do not suffer from an intellectual disability and are fully aware of their physical impairment, which we must not make worse without an effort for adequate treatment. This case study presents our solution of a supracondylar femoral fracture in a patient with achondroplasia and extreme obesity. A proximal humeral nail was used for distal femoral fracture osteosynthesis by a retrograde approach. To the knowledge of authors, this study reports on the first case of supracondylar femoral fracture surgery in patients with achondroplasia. Key words achondroplasia, dwarfism, supracondylar femoral fracture, extreme obesity.PURPOSE OF THE STUDY The purpose of this study is to reveal the waste of water by medical staff hand scrubbing preoperatively in the operation theatre, draw attention to the water consumption with small precautions. The study compares motion-sensitive sensor tap with an uncensored classic tap, to assess the difference of water consumption during hand scrubbing. MATERIAL AND METHODS The presented study compared two groups; hand scrubbing with sensory tap was enrolled as group A and classic tap with running water was enrolled as group B. Three participants were included in each group. Operation faucets with a motion-sensitive sensor and timekeeper were used in group A. Running water from a tap in 10 seconds was measured with the help of a measuring cup. The water amount after 3 minutes of washing was also measured. The difference between the two obtained data was compared. The obtained data were also multiplied to the global surgical data. RESULTS Measurements were performed with a measuring cup and it was meastive in using the natural resources economically and protecting these resources. Key words water, operation theatre, washing.PURPOSE OF THE STUDY The aim of our study is to investigate the reliabilities of the radiographic union score for tibial fracture (RUST) and modified RUST scoring systems in the evaluation of fracture healing in adult tibia fractures treated with intramedullary nailing and pediatric tibia fractures treated with closed reduction and cast immobilization and to compare the reliabilities between two groups. MATERIAL AND METHODS Between January 2016 and January 2020, the informations of patients (ages of 4-10) with tibia fractures treated with closed reduction and casting and patients (aged 18-65 years) with tibia fractures treated with intramedullary nailing were analyzed retrospectively. Forty-seven good quality AP and lateral radiographs (represent different healing stages) each for pediatric and adult fracture groups were selected and were included in two PPTs separately. The radiographs were assessed twice with an interval of three weeks by an observer group consisting of four senior orthopedic surgeons and frds pediatric tibia fracture, radiographic union score for tibial fracture (RUST), modified RUST, radiographic union, reliability.
