The review article focuses on the current scenario of molecularly imprinted hydrogels with emphasis on the imprinting strategies within hydrogels and challenges encountered, latent translational applications, and future perspectives.Shortcomings of oral donepezil administration in the treatment of Alzheimer's disease have paved the way for ongoing investigations towards more efficient and safe donepezil nose-to-brain delivery. Herein we present the development of advantageous powder platform for donepezil nose-to-brain delivery, coupling careful design of chitosan and mannitol-based carrier matrix with spray-drying technology advantages and early consideration of adequate nasal administration mode, employing QbD approach. Unprecedentedly, ultrasonic nozzle was used to atomise the drying feed in response to size-related requirements for nasal aerosol particles. The optimised spray-drying process resulted in free-flowable dry powder with a great majority of particles larger than 10 µm, ensuring localised nasal deposition upon aerosolization, as evidenced by using 3D-printed nasal cavity model. QbD approach coupling formulation, process and administration parameters enabled optimisation of drug deposition profile reaching tremendously high 65.5 % of the applied dose deposited in the olfactory region. The leading formulation exhibited favourable swelling, mucoadhesion, drug release and permeation-enhancing properties, suiting the needs for efficient brain-targeted delivery. Results of in vitro biocompatibility and physico-chemical stability studies confirmed the leading formulation potential for safe and efficient donepezil nose-to-brain delivery. The obtained results encourage extending the study to an appropriate in vivo model needed for the final proof-of-concept.The determination of the variability of critical dosage form attributes has been a challenge in establishing the quality of pharmaceutical products. During the development process knowledge is minimal. Consequently, ad hoc statistical tools such as hypothesis or significance tests, with calibrated decision error rates are often used in an effort to vet CQAs (Critical Quality Attributes) and keep their levels "between the curbs". As progress moves towards product launch, process and mechanistic understanding grows considerably and there are opportunities to leverage that knowledge for predictive modeling. Bayesian models offer a coherent strategy for integrating prior knowledge into both experimental design as well as predictive analysis for optimal risk-based decision making. This is because the Bayesian paradigm, unlike the frequentist paradigm, can assign probabilities to underlying states of nature that directly impact safety and efficacy such as the population distribution of tablet potencies or dissolution profiles in a batch. However, there are challenges and reluctance in switching to a predictive modeling quality framework once regulatory approval has been attained. This paper offers encouragement to make this switch. In this paper, we review a joint Long Island University - Purdue University (LIU-PU) FDA funded project whose purpose was to further integrate the concepts of this adaptive approach to lot release with the rationale and methods for data generation and curation and to extend the testing of this approach. We discuss the utility of the approach in product development. We consider the regulatory compliance implications, with examples, and establish a potential way forward toward implementation of this approach for both industry and regulatory stake-holders.Six new sugar esters (1-6), named tenuifolisides F-G (1-2) and tenuifolioses W-Z (3-6), together with 16 known compounds (7-22) were isolated from the roots of Polygala tenuifolia. The chemical structures of the new compounds were elucidated by 1D, 2D NMR and HRESIMS techniques together with chemical methods. All the compounds were evaluated for the cytoprotective activity against hydrogen peroxide (H2O2)-induced oxidative stress in human keratinocyte HaCaT cells. Compounds 4, 5, 13, 20 and 22 showed strong cytoprotective effect.
Kinesio tapes (KTs) are tapes used in physical therapy and athletics. We sought to evaluate if wearing KTs for extended periods of time increases exposure to antibiotic resistant opportunistic pathogens and/or effects normal human skin bacteria.

The study consisted of 10 volunteers wearing 9 KTs on their arms for 5 consecutive days. Microorganisms were isolated from fragments collected on the second and fifth day then analyzed. Bacteria were identified using the BIOLOG system. Resistance to selected antibiotics was performed using E-Test. learn more The effect of KTs on the growth of Staphylococcus aureus, Staphylococcus epidermidis, and Micrococcus luteus was evaluated in a diffusion-based assay.

We found that KTs accumulated environmental bacteria. Among 22 species 8 were opportunistic pathogens, and all of them exhibited resistance to at least one antibiotic. None of the tapes produced inhibition zones against S. aureus. One tape, Leukotape P, caused growth inhibition in non-pathogenic S. epidermidis and M. luteus. The adhesive material of the tapes inhibited the growth of all tested bacteria.

These results indicate that KTs may increase the exposure to antibiotic resistant pathogens which can accumulate from the environment. Further, extended exposure could lead to changes in normal skin microbiota, potentially contributing to increased risks of skin infections.

The medium- and long-term effects of COVID-19 infection on pulmonary function are still unknown. The present study aimed to investigate the pulmonary functions in healthcare professionals who had persistent complaints after contracting COVID-19 and returning to work.

The study included COVID-19-infected healthcare professionals from the Düzce University Medical Faculty Hospital who volunteered to participate. Medical histories, medical records, pulmonary function tests, the diffusing capacity of the lungs for carbon monoxide (DLCO) test, and the 6-minute walk test (6MWT) were used to collect data from all participants.

The study included 53 healthcare professionals, with an average age of 38 ± 10 years (min 24 years and max 71 years), including 29 female (54.7%) and 24 male (45.3%) participants. Of the participants, 22.6% were smokers, 35.8% (19 individuals) had comorbidities, and 17% (9 individuals) were hospitalized. The mean length of stay was 9 ± 4 days (mean ± standard deviation). The most prevaleneffort dyspnea (24.6%), weakness (9.5%), and muscle aches (7.6%).

Significant persistent complaints (47.2%) and low DLCO levels (39.6%) were observed in healthcare professionals during control visits at a mean time of 3 months after the COVID-19 infection. Symptoms and spirometry measurements, including DLCO, may be helpful in the follow-up of healthcare professionals who contracted COVID-19. Further comprehensive studies with long-term follow-up periods are required.

Hospital-acquired infections represent increasing problems in health-care facilities worldwide. Adequate infection control measures are key elements in preventing those infections. Expert societies have published recommendations that help to reduce Hospital-acquired infections.

In November 2019, a questionnaire-based point-prevalence survey, eliciting the adherence of 14 Tyrolean hospitals to the recommendations of the Centers of Disease Control and Prevention (CDC) was performed. Additionally, standard infection control measures performed by different medical (clinical and infection control specialists) disciplines as well as the performed infection control measures of nurses and physicians were compared.

The survey revealed varying adherence to CDC-recommendations of different medical disciplines, with highest congruence by the infection control specialists and lower congruencies by all surveyed clinical disciplines. Concordance rate between nurses and physicians was high.

Explanations for the varying congruencies of clinical disciplines on the one hand and the infection control specialists on the other hand may be versatile. Possible lacks of knowledge about the required hygiene measures should be taken into account.

The present survey showed moderate adherence of Tyrolean hospitals to the recommendations provided by CDC, however with noticeable differences between different medical disciplines. Nurses and doctors in most cases reported identically.

Stabilized hypochlorous acid (HOCl) is increasingly used as a hospital disinfectant and antiseptic, yet its effect on N95 filtration facemask respirators (FFR) is unknown. These FFRs could also contribute to fomite-based transmission of nosocomial infections if worn for extended use between patient rooms.

Filtration performance of N95 FFR fabric swatches was assessed after various levels of HOCl exposure. N95 swatches were then contaminated with 10
Escherichia coli or 10
Staphylococci aureus and treated with HOCl solution, 70% ethyl alcohol, or normal saline. Surviving bacterial numbers were assessed by plate counts.

The size-dependent filtration efficiency of HOCl-sprayed N95 FFR fabric ranged from 96% to 100%, showing no significant change. Flow resistance testing revealed almost no change compared to control. Submersion in HOCl, but not spraying, had an excellent bactericidal effect on contaminated swatches.

The role of the outer hydrophobic layer of N95 FFRs is discussed regarding the effects of HOCl on filtration and bacterial decontamination.

N95 material, sprayed with or briefly submerged in HOCl, maintained its filtration function. HOCl delivery by spray pump, however, would not accomplish decontamination of extended use FFRs between patient encounters. HOCl submersion of intact FFRs, contaminated with various hospital pathogens, is worth further study.

Radiopharmaceuticals preparation unit, such as every aseptic preparation units, are strictly monitored in terms of microbiological contamination. Despite all biocontamination control procedures, our radiopharmacy unit faced repeated environmental contamination by Achromobacter spp which necessitated a large environmental investigation.

Microbiological controls were carried out using Count Tact agars (Biomérieux) for flat surfaces, dry swabbing for hard to reach areas and containers were filled with a sterile water solution (then filtrated on 0.45 µm membrane and seeded). Microbiological identification was performed by mass spectrometry (MALDI-TOF-MS, Brucker) on each positive sample.

Achromobacter spp was found in 10% of the 413 samples during the 8 months investigation period. The proportion of positive samples was stable among time but their location was unpredictable. The highest inoculum was finally found in the buckets used for biocleaning.

Samples from cleaning buckets taken by dry swabbing were at first negative, but the use of a non-routinely used sampling method allowed to discover the reservoir of this persistent contamination.
