The world is witnessing a rising number of preterm infants who are at significant risk of medical conditions. These infants require continuous care in Neonatal Intensive Care Units (NICU). Medical parameters are continuously monitored in premature infants in the NICU using a set of wired, sticky electrodes attached to the body. Medical adhesives used on the electrodes can be harmful to the baby, causing skin injuries, discomfort, and irritation. In addition, respiration rate (RR) monitoring in the NICU faces challenges of accuracy and clinical quality because RR is extracted from electrocardiogram (ECG). This research paper presents a design and validation of a smart textile pressure sensor system that addresses the existing challenges of medical monitoring in NICU. We designed two e-textile, piezoresistive pressure sensors made of Velostat for noninvasive RR monitoring; one was hand-stitched on a mattress topper material, and the other was embroidered on a denim fabric using an industrial embroidery machine. We developed a data acquisition system for validation experiments conducted on a high-fidelity, programmable NICU baby mannequin. We designed a signal processing pipeline to convert raw time-series signals into parameters including RR, rise and fall time, and comparison metrics. The results of the experiments showed that the relative accuracies of hand-stitched sensors were 98.68 (top sensor) and 98.07 (bottom sensor), while the accuracies of embroidered sensors were 99.37 (left sensor) and 99.39 (right sensor) for the 60 BrPM test case. The presented prototype system shows promising results and demands more research on textile design, human factors, and human experimentation.
Although respiratory allergies to house dust mites (HDMs) can often be controlled with symptomatic medications, some patients do not achieve satisfactory disease control.
To assess fortnightly fluctuations (notably worsening and/or exacerbations) in disease parameters among patients taking only symptomatic medications for HDM allergy.
In a 13-month, observational, multicenter survey of adults with a self-reported history of poorly controlled, moderate-to-severe, physician-diagnosed HDM respiratory allergy in France, Italy, and Spain, fortnightly telephone interviews were used to gather information on medication use, symptoms, the disease burden, and medical consultations from late May 2012 to early July 2013.
A total of 313 patients completed the study (
=114 in Italy, 92 in France, and 107 in Spain). Although most participants reported improvements in symptoms, a substantial minority (ranging from 12% to 44% per fortnightly telephone interview in 2012 and from 16% to 37% in 2013) complained of worsestigation. More prominence could be given to symptom control and a low exacerbation risk as treatment goals in allergic rhinitis.
Previous studies have shown that direct oral provocation tests, without prior skin testing, in children having delayed onset, benign rashes to beta-lactam antibiotic is safe and effective. Although, this test is useful in confirming drug hypersensitivity reactions, there is no standard protocol recommendation of drug provocation tests. This study aimed to evaluate the safety of the direct oral provocation test, using the Amoxicillin-2-step-challenge without prior skin testing, in children with history of non-immediate reactions to amoxicillin.
The Amoxicillin-2-step-challenge protocol was performed in children with history of non-immediate reactions to amoxicillin. This protocol is composed of 2 doses of amoxicillin, with a 30-min interval; continued for a total of 5 days. All of the patients had not undergone skin testing before the oral provocation test.
This study included 54 children, having a median age of 6.6 years, with 70.4% being male. Amoxicillin and amoxicillin-clavulanic acid were reported as the culprit drug in 75.9% and 24.1%, respectively. The index reactions were maculopapular (MP) rash in 79.6% and delayed urticarial rash/angioedema in 20.4%. Five patients (9.3%) had a reaction during the provocation test, all of these patients had delayed urticaria and were treated with oral antihistamine. However, 1 patient developed a fever alongside an MP rash. Laboratory investigation for this patient showed increased atypical lymphocytes and liver enzymes elevation.
Direct oral provocation tests, using the Amoxicillin-2-step-challenge, without prior skin testing, revealed good, immediate safety for the diagnosis of amoxicillin hypersensitivity in children with history of non-immediate reactions to amoxicillin.

Effective vaccines are key components in overcoming the COVID-19 pandemic, so understanding the possible allergic reactions they might cause is essential. Data so far shows that the relative risk of a severe allergic reaction is slightly increased when compared with the overall risk of anaphylaxis due to vaccines, albeit the absolute risk remaining quite low. However, it is also important to be aware of what the population is searching for online, especially regarding controversial topics such as the CoViD-19 vaccines and severe allergic reactions that may result.
We conducted a Google Trends worldwide online search to look for any increase in Relative Search Volume (RSV) in the last 5 years regarding the search terms "Anaphylaxis" and "Vaccine anaphylaxis".
We found that there was a major increase in the "Anaphylaxis" and "Vaccine anaphylaxis" RSV in December 2020, continuing up to January 2021, worldwide and in four selected countries.
We believe this sudden interest in anaphylaxis is related to reports of severe allergic reactions to these vaccines. This can lead to hesitancy in regards to vaccination, and our duty as health professionals is to recommend vaccination and assure that the vaccines are administered in well-equipped vaccination centres, assuring registries of all adverse / allergic reactions.

Botanical supplements have been proven to provide beneficial health effects. However, they can induce unintended adverse events such as hepatotoxicity.
extract (OIE, Sabroxy®) has several health benefits including anti-inflammatory, anti-arthritic, antifungal, antibacterial, and neuroprotective effects. It is currently unknown whether OIE has the potential to induce hepatotoxicity.
In the current study, we sought to determine whether OIE can induce hepatotoxicity in C57BL/6J mouse model.
The male mice were fed powdered rodent food (control group) or powdered rodent food mixed with OIE (Sabroxy®, 500mg/kg) daily for 4 weeks. Following the treatment, we assessed liver histology and serum levels of biomarkers commonly associated with liver damage, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP).
No significant alterations were observed in liver histology, and serum levels of ALT, AST, ALP, bilirubin, albumin, globulin and total protein in the OIE fed mice compared to the control mice.
Taken together, our results suggest that OIE, when fed at its physiologically relevant dosage, does not induce hepatotoxicity in C57BL/6J mice.

Telemedicine has become popular as an alternative for in-person weight loss treatment during the COVID-19 pandemic. This review focuses on weight loss interventions utilizing real-time telemedicine.
Telemedicine interventions are usually run as a weekly counseling and educational session or as a complement to a primarily Web-based intervention. A wide variety of healthcare professionals may provide the intervention. Common content includes portion control, increased physical activity, and relapse prevention. Self-monitoring is associated with intervention success. Modalities considered include online chats, text messages, phone calls, and videoconferences. Videoconferencing may be especially useful in capturing the interpersonal connection associated with in-person care but is understudied compared to other modalities. While many interventions show improvements in weight and weight-related outcomes, small sample sizes limit generalizability. Technology access and digital literacy are both necessary.
Telemedicine interventions can successfully help patients with obesity lose weight. Telemedicine interventions provide a safe, remote alternative and may expand treatment access to hard-to-reach populations. Further research is needed on telemedicine weight loss treatments for seniors, men, and ethnic minorities, as well as on the impact of long-term interventions.

GSK-4362676 cell line While much of the focus has been on the nanostructures that generate enhanced and nano-confined optical fields, we herein highlight recent work from our groups that uses the molecular response in surface and tip enhanced Raman scattering (SERS and TERS, respectively) to investigate different aspects of the local fields. TERS provides access to ultra-confined volumes, and as a result can further explore and explain ensemble-averaged SERS measurements. Exciting and distinct molecular behaviors are observed in the quantum limit of plasmons, including molecular charging, chemical conversion, and optical rectification. Evidence of multipolar Raman scattering from molecules additionally provides insights into the inhomogeneous electric fields that drive SERS and TERS and their spatial and temporal gradients. The time scales of these processes show evidence of cooperative nanoscale phenomena that altogether contribute to SERS and TERS.Nonlinear microscopy has enabled additional modalities for chemical contrast, deep penetration into biological tissues, and the ability to collect dynamics on ultrafast timescales across heterogenous samples. The additional light fields introduced to a sample offer seemingly endless possibilities for variation to optimize and customize experimentation and the extraction of physical insight. This perspective highlights three areas of growth in this diverse field the collection of information across multiple timescales, the selective imaging of interfacial chemistry, and the exploitation of quantum behavior for future imaging directions. Future innovations will leverage the work of the studies reviewed here as well as address the current challenges presented.
