The utilization of skin care products and cleansers is a prevalent method for maintaining facial skin health. However, excessive use of these products is an unnoticed factor that can result in serious skin problems. Currently, there are no products on the market to provide users with skin acclimatization and restoration services. Herein, we introduce a facial mask with a smart pH sensor to monitor and repair facial skin. Specifically, bacterial cellulose fragments were mechanically dispersed, co-mingled with carboxymethyl cellulose and hydroxypropyltrimethylammonium chloride chitosan, with anthocyanin added as a pH-indicating reagent. The composite mask was then prepared by hot air drying. This mask exhibited notable anti-hornification effect, robust water absorption, water retention, wet strength, and antibacterial and antioxidant properties, making it suitable for a high-end facial mass base material with an excellent pH sensitivity within the range of 2.0-12.0, which could be observed directly through colorimetry with the naked eye.

Unlabelled: Face masks became a part of everyday life during the SARS-CoV-2 pandemic. Previous studies showed that the face cognition mechanism involves holistic face processing, and the absence of face features could lower the cognition ability. This is opposed to the experience during the pandemic, when people could correctly recognize faces, although the mask covered a part of the face.

Objective: The primary aim of this investigation is to assess the effectiveness of implementing an innovative immobilization approach, spec ically the utilization of personalized open-face masks in combination with styrofoam fixation, for head and neck cancers receiving radiotherapy. The study seeks to evaluate the influence of this method on improving patients' precision in positioning and their overall comfort during the treatment process, in addition to exploring its potential capacity to mitigate the occurrence of anxiety and depression in this patient population.
Methods: A prospective, randomized controlled trial was undertaken to investigate the comparative efficacy of two immobilization approaches for the radiotherapy treatment of head and neck cancers.

Introduction: The COVID-19 burden, coupled with unprecedented control measures including physical distancing, travel bans, and lockdowns in cities, has undoubtedly far-reaching consequences on healthcare services and has affected human immunodeficiency virus (HIV) and tuberculosis (TB) health services in both low- and high-income countries. This study, therefore, explored the perspective of HIV and TB health service providers to better understand how the pandemic impacted health service delivery in Ghana.
Method: This qualitative explorative study was conducted among HIV and TB healthcare providers (n = 30) in six districts of Ghana from March to May 2021 using in-depth interviews.
