It has been implemented in clinical practice. Two groups of patients were examined according to the baseline and optimized protocols, respectively. The new SPECT/CT protocol substantially reduced patients' radiation exposure compared to the old protocol while maintaining the required diagnostic quality of SPECT and CT images.

In the study, we present a methodology that finds a compromise between diagnostic information and patient exposure during bone SPECT/CT procedures.

Modeling of plasmid transfer is essential to uncovering the fundamentals of resistance transfer and for the development of predictive measures to limit the spread of resistance. However, a major limitation in the current understanding of plasmids is the incomplete characterization of the conjugative DNA transfer mechanisms, which conceals the actual potential for plasmid transfer in nature. Here, we consider that the plasmid-borne origin-of-transfer substrates encode specific DNA structural properties that can facilitate finding these regions in large datasets and develop a DNA structure-based alignment procedure for typing the transfer substrates that outperforms sequence-based approaches. Thousands of putative DNA transfer substrates are identified, showing that plasmid mobility can be twofold higher and span almost twofold more host species than is currently known. click here Over half of all putative mobile plasmids contain the means for mobilization by conjugation systems belonging to different mobility groups, which can hypothetically link previously confined host ranges across ecological habitats into a robust plasmid transfer network. This hypothetical network is found to facilitate the transfer of antimicrobial resistance from environmental genetic reservoirs to human pathogens, which might be an important driver of the observed rapid resistance development in humans and thus an important point of focus for future prevention measures.Microrobots for targeted drug delivery are of great interest due to their minimal invasiveness and wireless controllability. Here, a magnetically driven porous degradable microrobot (PDM) is reported that consists of a 3D printed helical soft polymeric chassis made of a poly(ethylene glycol) diacrylate and pentaerythritol triacrylate matrix containing magnetite nanoparticles and the anticancer drug 5-fluorouracil (5-FU). The encapsulated Fe3 O4 nanoparticles render the PDM a precise wireless magnetic actuation by means of rotating magnetic fields (RMFs). The increased surface area of the porous PDM facilitates the acoustically induced drug release due to a higher response to the acoustic energy. The drug release profile from the PDM can be selected on command from three different modes, referred to herein as natural, burst, and constant, by differentiating the ultrasound exposure condition. Finally, in vitro test results reveal different therapeutic results for each release mode. The observed great reduction of cancer cell viability in the burst- and constant-release modes confirms that ultrasound with the proposed PDM can enhance the therapeutic effect by increasing drug concentration and sonoporation.
The emergence of new treatments for spinal muscular atrophy (SMA) is revolutionary, especially for SMA type 1 (SMA1). Data on respiratory outcomes remain sparse and rely mostly on randomized clinical trials. We report our experience of Nusinersen-treated SMA1 patients in real-world settings.

Data from SMA1 patients treated with Nusinersen were prospectively collected between 1/2017 and 1/2020. Respiratory variables included the use of assisted ventilation, the use of mechanical insufflation-exsufflation (MIE), respiratory complications, and death or treatment cessation due to respiratory reasons.

Twenty SMA1 patients were assessed before and after 2 years of Nusinersen treatment which was initiated at a median age of 13.5 months (range, 1-184). At baseline, 16 patients were using assisted ventilation, eight noninvasive and eight invasive. Twelve patients were using permanent ventilation and four partial ventilation. After 2 years of treatment, there was no change in respiratory support among ventilated patients. All four patients who were free from respiratory support at baseline required the initiation of assisted ventilation during the study period. All 20 patients used MIE after 2 years of treatment. Two patients died from acute respiratory failure and one sustained severe brain injury. Four patients had chronic and/or recurrent atelectasis.

Most of our patients were stable in their need for assisted ventilation and did not worsen as expected in SMA1, nor did they improve as might be hoped. Future studies are needed to determine if earlier treatment with Nusinersen might result in respiratory outcomes superior to those reported in this real-life study.

Plastic cannulas (PC) have shown efficacy in haemodialysis (HD) and are presented as a positive innovation for patients and vascular access survival.

To analyse Spanish HD nurses' experience of using PC.

Cross-sectional observational study.

An ad hoc questionnaire was administered on nurses' experience of PC use.

A total of 163 Spanish HD nurses were surveyed, of whom 42.3% had PC in their workplace and 50.9% had used them. In all, 55.8% had received training and 77.9% wished to receive more training. These needles were significantly more available in public institutions than in private centres (p < 0.001). There was no significant difference between years of experience and having received training (p = 0.915). There was a moderate-strong correlation (ρ = 0.659) between greater professional satisfaction with the product and greater patient satisfaction (p < 0.001). The nurses would make a median of two [P
