Purpose: Using a multiple-step testing medium-risk-level compounding test procedure, the evaluation of two work-practice changes to determine if the changes could effectively reduce the potential for contamination occurrence was conducted.
Summary: Along with training and evaluation of aseptic sterile compounding techniques, each individual pharmacist and pharmacy technician at M. D. Anderson Cancer Center must successfully demonstrate aseptic preparation competency annually by performing the complicated multistep aseptic transfers of growth medium with no resulting growth of microorganisms. The multistep aseptic transfers are designed to simulate manual compounding of the most complicated medium-risk-level preparations anticipated as specified in the United States Pharmacopeia's chapter 797. An evaluation of two modest and simple work-practice changes was conducted: The use of bare hands and nonsterile gloves with only initial disinfection with 70% isopropyl alcohol (IPA) during years 1 and 2 (group A) was compared with the use of nonsterile chemotherapy gloves with initial and repeated disinfection with IPA for year 3 (group B) and the use of sterile gloves with initial and repeated disinfection with IPA for year 4 (group C). The process involved multiple discrete manipulations, including reconstitution of dry-growth medium; transfers of growth medium from vials and ampules using syringes, needles, a dispensing pin, and a filter straw; and transfers to an empty plastic i.v. bag. For groups B and C, significant reductions in contaminated samples were found compared with group A.
Conclusion: The use of protective chemotherapy gloves that were repeatedly disinfected with IPA decreased the contamination rate of pharmacy-compounded sterile preparations.

Finding ways to produce dense and smooth perovskite films with negligible defects is vital for achieving high-efficiency perovskite solar cells (PSCs). Herein, we aim to enhance the quality of the perovskite films through the utilization of a multifunctional additive in the perovskite anti-solvent, a strategy referred to as anti-solvent additive engineering. Specifically, we introduce ortho-substituted-4'-(4,4″-di-tert-butyl-1,1':3',1″-terphenyl)-graphdiyne (o-TB-GDY) as an AAE additive, characterized by its sp/sp-cohybridized and highly π-conjugated structure, into the anti-solvent.

Wearable motion capture gloves enable the precise analysis of hand and finger movements for a variety of uses, including robotic surgery, rehabilitation, and most commonly, virtual augmentation. However, many motion capture gloves restrict natural hand movement with a closed-palm design, including fabric over the palm and fingers. In order to alleviate slippage, improve comfort, reduce sizing issues, and eliminate movement restrictions, this paper presents a new low-cost data glove with an innovative open-palm and finger-free design.

The use of personal protective equipment such as gloves and masks and protective measures such as repeated contact of hands with water and skin disinfectants are recommended to prevent the spread of Corona virus disease 2019 (COVID-19). However, these hygiene measures may cause skin injury and skin diseases, including superficial-cutaneous-fungal infections (SCFIs). The aim of this study was to determine the prevalence and comparison of SCFIs before and during the COVID-19 pandemic.
