sociated with a lower BMD; thus these data at IBD diagnosis should be considered as a risk factor for bone disease in the pediatric population.
COVID-19, the novel coronavirus has caused a global pandemic affecting millions of people around the world. Although children, including children with cancer, have been found to be affected less commonly and less severely than adults, indirect effects of the pandemic on the diagnosis and treatment of children with cancer have been less described.

A survey was performed in the four largest tertiary pediatric hematology-oncology medical centers in Israel. Clinical and laboratory data were collected from the medical files of patients diagnosed or treated with cancer during April-October 2020.

Seventeen patients are described, who had a significant delay in diagnosis or treatment of cancer. These represent approximately 10% of all pediatric cancer diagnosed during the study period in these centers. A main cause of delay was fear of exposure to COVID-19 (fears felt by the patient, parent, physician, or decision-makers at the institution; or the implementation of national guidelines). Delays also resulted from co-infection with COVID-19 and the attribution of the oncologic symptoms to the infection. In addition, treatment was delayed of patients already diagnosed with cancer, due to COVID-19 infection detected in the patient, a family member, or a bone marrow donor.

Fear from the COVID-19 pandemic may result in delayed diagnosis and treatment of children with cancer, which may carry a risk to dismal prognosis. It is crucial that pediatricians and patients alike remember that other diseases still prevail and must be thought of and treated in a timely fashion.

Despite much focus on enteral applications, there has been a lack of research focused on potential benefits of 3D printing for parenteral applications such as wound dressings, biomedical devices, and regenerative medicines. 3D printing technologies, including fused deposition modeling, vat polymerization, and powder bed printing, allow for rapid prototyping of personalized medications, capable of producing dosage forms with flexible dimensions based on patient anatomy as well as dosage form properties such as porosity. Considerations such as printing properties and material selection play a key role in determining overall printability of the constructs. These parameters also impact drug release kinetics, and mechanical properties of final printed constructs, which play a role in modulating immune response upon insertion in the body. Despite challenges in sterilization of printed constructs, additional post-printing processing procedures, and lack of regulatory guidance, 3D printing will continue to evolve to meet the needs of developing effective, personalized medicines for parenteral applications.Well-defined crystal structures of Pd-doped WO3 nanorods were assembled on graphitic carbon sheets (Pd-WO3/g-C3N4) for ultrasensitive detection of paraoxon-ethyl (PEL) using an electrochemical method. The electrochemical behavior of PEL on the Pd-WO3/g-C3N4 hybrid composite was investigated using cyclic voltammetry (CV) and amperometric techniques. The Pd-WO3 crystallite was seen to modify the kinetics of g-C3N4, which improved the reduction/redox peak currents of PEL at the Pd-WO3/g-C3N4 composite compared to those of the g-C3N4 and WO3/g-C3N4-modified electrode. Moreover, the π-π interaction and hydrogen bond between the PEL and Pd-WO3/g-C3N4 composite improved the charge-transfer properties. The Pd-WO3/g-C3N4 hybrid composite was therefore able to obtain an enhanced sensitivity (3.70 ± 0.05 μA μM-1 cm-2) and low detection limit (0.03 nM; S/N = 3) with a wide range of linear concentrations (0.01-60 and 80-900.0 ± 5 μM) at applied potential of - 0.63 V (vs. Ag/AgCl). The detection of PEL in agricultural water and soil samples was successfully demonstrated with satisfactory RSD of 2.5 to 3.1% and recovery results of 97 to 102%, respectively.
The increased consumption of plant-based diets has encouraged studies of bone mineral density (BMD). The present systematic review and meta-analysis compared the effects of plant-based and omnivorous diets on BMD.

We searched the Cochrane Library, PubMed, EMBASE, and the Web of Science to July 1, 2020. We used the mean differences (MDs) with 95% CIs to compare group outcomes. We compared the lumbar spine, femoral neck, and whole-body BMDs of those on plant-based and omnivorous diets. We performed subgroup analyses by various clinical characteristics. Two reviewers independently assessed trial quality and extracted data. All statistical analyses were performed using Review Manager version 5.2.

A total of 17 cross-sectional studies including 13,888 patients were identified. The pooled results indicated that those on plant-based diets (compared to omnivores) exhibited lower BMDs at the lumbar spine (MD - 0.04; 95% CI - 0.06 to - 0.02; P < 0.0001) and femoral neck (MD - 0.04; 95% CI - 0.05 to - 0.02; P < 0.00001), and a reduced whole-body BMD (MD - 0.03; 95% CI - 0.06 to - 0.01; P = 0.0009). Both vegetarians and vegans exhibited lower lumbar spine, femoral neck, and whole-body BMDs than omnivores.

Plant-based diets were associated with lower BMDs than those of an omnivore population. Plant-based diets may compromise overall bone health; prospective research is required.

The effect of the headspace oxygen levels, ampoule color, manufacturer, and size on the stability of butorphanol tartrate formulation were evaluated. The headspace oxygen levels controlled by nitrogen purging were found to be particularly effective in improving stability of the butorphanol formulation, especially below 2%. Although it is a photolabile drug, butorphanol tartrate was getting degraded at much higher extent in amber color ampoules in comparison to clear ampoules. The degradation by oxidation was found to be a free radical-mediated process catalyzed by the presence of iron ions leached from the amber ampoules. The ampoule manufacturers also had a significant effect on the stability of butorphanol. Two-milliliter ampoules provided a better stability of the butorphanol tartrate injection than 1mL ampoules as 2-mL ampoules had the lower headspace oxygen level at the same level of oxygen content.
