Currently the prevalence of pneumococcal coinfection in patients with COVID-19 is unknown. In this work we present its clinical characteristics, evolution and treatment.

Retrospective data collection from August to October 2020 in two hospitals in the Murcia region.

Eighteen patients had COVID-19 diagnosed by PCR and pneumococcal infection confirmed by antigenuria, which represented a prevalence of 2%. A total of 88% had radiological alterations upon admission (two patients had an X-ray within normality) and 29% had elevated procalcitonin. Mortality in our series was 12%.

It could be reasonable to consider the start of antimicrobial therapy in those cases in which there is a moderate or high suspicion of bacterial coinfection, being essential the early suspension of antibiotic treatment if it is not confirmed.

General anesthesia or sedation is commonly required for pediatric patients undergoing magnetic resonance imaging (MRI) scans, and airway management during the procedure is the highest concern for anesthesiologists owing to the limited access to the patient in the MRI unit. The use of supraglottic airway devices (SADs) has recently become more popular than endotracheal tubes; however, the feasibility of using SADs for children in MRI suites was reported only in a few studies that involved healthy patients.

We present a successful case series of 30 pediatric patients, and the majority are high-risk patients, including patients with aromatic L-amino acid decarboxylase (AADC) deficiency, mitochondrial disease, and tuberous sclerosis, using either i-gel or laryngeal masks for airway maintenance during MRI examination.

A total of 38 MRI exams were conducted; the patients' median age was 4 (range 1.6-17.0 years), and the mean examination time was 50.87 minutes. No patient experienced oxygen desaturation, and only 1 patient with AADC deficiency had an episode of hypotension. The MRI scans were completed without interruption with an adequate image quality according to a specialized radiologist.

From the clinical point of view, this case series demonstrated a broader application of SADs for airway maintenance during MRI scans for pediatric patients with a high risk during anesthesia rather than only for a healthy patient population.

For various applications in quantum science, efficiently and accurately achieving a quantum transition frequency is essential. However, the exact relation between a desired transition frequency and the controllable experimental parameters is usually absent. Here, we propose an efficient scheme to search the suitable conditions for a desired magneto-sensitive transition via an adaptive Bayesian algorithm and experimentally demonstrate it by using coherent population trapping in an ensemble of laser-cooled 87Rb atoms. The transition frequency is controlled by an external magnetic field, which can be tuned in realtime by applying a d.c. voltage. Through an adaptive Bayesian algorithm, the voltage can automatically converge to the desired one from a random initial value only after few iterations (N ≥ 10). The response time is limited by the time of obtaining the spectrum signal, which is about 50 s for 10 iterations in our experiment. Imatinib In particular, when the relation between the target frequency and the applied voltage is nonlinear (e.g., quadratic), our algorithm shows significant advantages over traditional methods. This work provides a simple and efficient way to determine a transition frequency, which can be widely applied in the fields of precision spectroscopy, such as atomic clocks, magnetometers, and nuclear magnetic resonance.The chiroptical response of the chiral metasurface can be characterized by circular dichroism, which is defined as the absorption difference between left-handed circularly polarized incidence and right-handed circularly incidence. It can be applied in biology, chemistry, optoelectronics, etc. Here, we propose a dynamically tunable chiral metasurface structure, which is composed of two metal split-ring resonators and a graphene layer embedded in dielectric. The structure reflects right-handed circularly polarized waves and absorbs left-handed circularly polarized waves under normal incidence. The overall unit structural parameters of the chiral metasurface were discussed and analyzed, and the circular dichroism was 0.85 at 1.181 THz. Additionally, the digital imaging function can be realized based on the chiral metasurface structure, and the resolution of terahertz digital imaging can be dynamically tuned by changing the Fermi level of graphene. The proposed structure has potential applications in realizing tunable dynamic imaging and other communication fields.Rotationally resolved, broadband absorption spectra of the fundamental vibrational transition of the asymmetric C-H stretch mode of methane are measured under single-laser-shot conditions using time-resolved optically gated absorption (TOGA). The TOGA approach exploits the difference in timescales between a broadband, fs-duration excitation source and the ps-duration absorption features induced by molecular absorption to allow effective suppression of the broadband background spectrum, thereby allowing for sensitive detection of multi-transition molecular spectra. This work extends the TOGA approach into the mid-infrared (mid-IR) spectral regime, allowing access to fundamental vibrational transitions while providing broadband access to multiple mid-IR transitions spanning ∼150 cm-1 (∼160 nm) near 3.3 μm, thereby highlighting the robustness of this technique beyond previously demonstrated electronic spectroscopy. Measurements are conducted in a heated gas cell to determine the accuracy of the simultaneous temperature and species-concentration measurements afforded by this single-shot approach in a well-characterized environment.
