During the coronavirus disease 2019 (COVID-19) pandemic, the general public has been advised to wear masks or improvised face coverings to limit transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, there has been considerable confusion and disagreement regarding the degree to which masks protect the wearer from airborne particles.

To evaluate the fitted filtration efficiency (FFE) of various consumer-grade and improvised face masks, as well as several popular modifications of medical procedure masks that are intended to improve mask fit or comfort.

For this study conducted in a research laboratory between June and August 2020, 7 consumer-grade masks and 5 medical procedure mask modifications were fitted on an adult male volunteer, and FFE measurements were collected during a series of repeated movements of the torso, head, and facial muscles as outlined by the US Occupational Safety and Health Administration Quantitative Fit Testing Protocol. The consumer-grade masks tetudy demonstrates that the FFEs of consumer-grade masks available to the public are, in many cases, nearly equivalent to or better than their non-N95 respirator medical mask counterparts.

Incision-related Descemet membrane detachment (DMD) is a common complication of cataract surgery. learn more Most postoperative severe DMD that leads to corneal decompensation originates from intraoperative incision-related DMD. It is important to determine the incidence, extent, and associated risk factors of intraoperative DMD at each step of surgery to help in formulating precise and effective prevention strategies.

To investigate the intraoperative development of incision-site DMD associated with a 2.2-mm clear corneal incision during cataract surgery and to analyze its associated factors.

In this case series, consecutive, prospectively enrolled 133 patients with cataract 50 to 90 years of age (133 eyes) undergoing coaxial 2.2-mm clear corneal microincision phacoemulsification with intraocular lens (IOL) implantation between January 1 and March 31, 2019, at Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou, China, were studied.

Coaxial 2.2-mm clear corneal microincision phacoemulsification with s has the greatest association with incisional DMD. Decreasing ultrasonic energy and phacoemulsification time may reduce the severity of incisional DMD.

The results of this case series suggest that friction of surgical instruments has the greatest association with incisional DMD. Decreasing ultrasonic energy and phacoemulsification time may reduce the severity of incisional DMD.

The aims of this paper were to present data on the implementation and coverage of simultaneous Universal Neonatal Hearing and Vision Screening programmes and to evaluate the organization and management of these healthcare procedures in Italy.

Data were collected through a nationwide survey conducted in 2018. All maternity wards active in Italy in 2017 were included.

Hearing screening. Overall 427,365 newborns out of 448,386 (95.3%) received the hearing screening test (first level) in 391 out of the 409 maternity hospitals (95.5%), with a national mean referral rate of 3.63% (SD ± 4.58). A statistically significant increase (p<0.034) of newborns sent to audiological examination was found in maternity hospitals with Neonatal Intensive Care Unit (NICU) with "TEOAE only" protocol (9.32% SD ± 7.57), compared to those with "TEOAE/AABR" (3.0% SD ± 3.29). Vision screening. Overall 335,262 newborns out of 448,386 (74.7%) received vision screening (Red Reflex test) for vision impairment in 302 out of 409 mater a new multi-disciplinary approach to sensorineural disability. The use of both ABR and TEOAE tests in the hearing screening decreases the number of newborns sent for audiological evaluation, with a notable reduction of costs. The consideration that ocular problems are two to three times more common in deaf and hearing impaired children than their in hearing peers, confirms the importance of establishing guidelines for simultaneous hearing and vision screening, that favors the formation of a multi-disciplinary team (pediatrician, audiologist, ophthalmologist).

The results of the present study highlight the need for comprehensive strategies targeting the appropriate use of antibiotics and infection control measures.

In the last decades, multidrug-resistant gram-negative bacteria have been increasing and they are involved in severe healthcare associated infections. In treating drug-resistant gram-negative bacterial infections, carbapenems are generally administered as a last choice. However, the rate of carbapenemresistant bacteria is constantly increasing the last years. The aim of the present study is to describe the relationship between the rate of carbapenem-resistant gram-negative bacteria and antibiotic consumption intensity.

In 2017, the Sicilian Region implemented a regional surveillance system to describe and analyze consumption of antibiotics in hospital settings, as well as prevalence of antibiotic resistant microorganisms.

Resistance data were retrospectively collected from routinary clinical antimicrobial susceptibility tests. Resistance rates (Rial for systemic use) (R=0.402, p<0.05).

In 2015, the overall prevalence of carbapenem-resistant Klebsiella pneumoniae isolates was 43.9 %, and was positively correlated with beta-lactam consumption (R=0.529, p less then 0.01), and with carbapenem consumption (R=0.364, p less then 0.05). In 2016, the overall prevalence of carbapenem-resistant Klebsiella pneumoniae isolates was 53.8 %, and was positively correlated with carbapenem antibiotic consumption (R=0.364, p less then 0.05). In 2017, the overall prevalence of carbapenem-resistant Klebsiella pneumoniae isolates was 58.7 %, and was significantly positively correlated with carbapenem antibiotic consumption (R=0.427, p less then 0.05). In 2015, the overall prevalence of carbapenem-resistant Escherichia coli isolates was 6.5 %, and was significantly positively correlated with antibiotic consumption for the ATC class J01 (i.e., antibacterial for systemic use) (R=0.402, p less then 0.05).
