In conclusion, among SOT recipients with confirmed infection, only 51% of patients had detectable anti-nucleocapsid antibodies, and transplant-related variables including the level and nature of immunosuppression were important predictors. These findings raise the concern that SOT recipients with COVID-19 may be less likely to form SARS-CoV-2 antibodies.
Childhood acute lymphoblastic leukemia (ALL) is the most common pediatric malignancy. The onset of obesity during childhood ALL has been well established and is associated with inferior survival rates and increased treatment-related toxicities. This pilot study sought to determine if a dietary intervention is feasible and minimizes weight gain during the initial phases of treatment for ALL.
Participants were recruited from four institutions, fluent in English or Spanish, between 5 and 21years old, and enrolled within 3days of starting induction therapy. Participants were counseled for 6months to follow a low glycemic diet. Dietary and anthropometric data were collected at diagnosis, end of induction, and end of month 6 (NCT03157323).
Twenty-three of 28 participants (82.1%) were evaluable and included in the analysis. Dietary changes targeted by the nutrition intervention were successful; sugar intake declined (P=.003), whereas vegetable intake increased (P=.033). The majority of participants were able to adhere to the dietary principles prescribed ≥70.0% reduced glycemic load and ≥60.0% increased fiber intake and decreased sugar intake. Importantly, we did not observe an increase in body mass index z-score during induction or over the 6-month intervention period. Most families found the nutrition intervention easy to follow (60%) and affordable (95%) despite simultaneous initiation of treatment for ALL.
A 6-month nutrition intervention initiated during the initial phase of treatment for childhood ALL is feasible and may prevent weight gain. Our preliminary findings need to be confirmed in a larger clinical trial.

Pre-operative templating using digital radiography is an effective method of planning for total hip arthroplasty (THA) and requires a generalised fixed magnification factor (MF) or external calibration markers (ECM). The effect on image magnification when changing source-to-image distance (SID), object-to-image distance (OID) and different imaging conditions is not well described. This study aims to quantify the range of effects manipulation of radiographic parameters can have on image magnification across different body habitus and imaging conditions.
A simple phantom study was performed. A 25mm ECM was placed at eight different OID values along the anterior-posterior phantom plane at three different SID values and imaging conditions, and X-rays were obtained. On each radiograph, the ECM was measured using a line calliper tool by three radiographers and recorded. The MF was calculated and recorded.
The smallest observed image MF was 1.16, for an 8cm OID, 120cm SID with the ECM placed within the central ray and the X-ray detector in bucky underneath the X-ray table. The largest image MF was 1.40 for a 15cm OID, 100cm SID with the X-ray detector placed underneath an emergency department imaging trolley.
Digital pre-operative templating for THA relies on accurate radiographic positioning and is dependent of the patient body habitus, radiographic parameters and imaging conditions selected by the radiographer. The use of appropriately positioned ECMs - placed medially between the patient's internally rotated legs at the level of the greater trochanter, lowers the potential for magnification inaccuracies.

Given the condition of patients with dyspnea, lung biopsies are limited because of their invasiveness. A 72-year-old man presented with chronic atrial fibrillation and a high right heart load, as determined using ultrasonography. He had previously undergone resection of the left axillary skin secondary to extramammary Paget's disease (EMPD). Clinically, PTTM was suspected and pulmonary wedge aspiration cytology, collected from the pulmonary artery during catherization, was performed. Cytologically, the tumor demonstrated three-dimensional cell clusters with good cohesion and molding by the blood vessel lumen. Additionally, endothelial-like cells were observed at the periphery of the tumor clusters; fibrin was evident in the clusters. The tumor cells were large, round, and had high nuclear/cytoplasmic ratios. The nuclei demonstrated a variety of sizes and were irregularly shaped, with prominent nucleoli; cells undergoing mitosis were evident. The tumor cells were suspected of being poorly differentiated adenocarcinoma cells, consistent with PTTM. Two days after the aspiration cytology, the patient died and a pathological autopsy was performed. Histologically, the PTTM was determined to have caused the pulmonary hypertension and the primary PTTM site was apparently derived from the EMPD. For rapid diagnoses, an understanding of the tumor's cytological features is important and should contribute to early treatment intervention. Aspiration cytology, using pulmonary artery blood samples, during catherization is a useful tool for diagnosing PTTM.Layered metal oxides including MoO3 and WO3 have been widely explored for biological applications owing to their excellent biocompatibility, low toxicity, and easy preparation. However, they normally exhibit weak or negligible near-infrared (NIR) absorption and thus are inefficient for photo-induced biomedical applications. selleck inhibitor Herein, the structural engineering of layered MoO3 and WO3 nanostructures is first reported to activate their NIR-II absorption for efficient photothermal cancer therapy in the NIR-II window. White-colored micrometre-long MoO3 nanobelts are transformed into blue-colored short, thin, defective, interlayer gap-expanded MoO3-x nanobelts with a strong NIR-II absorption via the simple lithium treatment. The blue MoO3-x nanobelts exhibit a large extinction coefficient of 18.2 L g-1 cm-1 and high photothermal conversion efficiency of 46.9% at 1064 nm. After surface modification, the MoO3-x nanobelts can be used as a robust nanoagent for photoacoustic imaging-guided photothermal therapy to achieve efficient cancer cell ablation and tumor eradication under irradiation by a 1064 nm laser.
