Critchley E, Pemberton MN. The use of latex and non-latex gloves and dental equipment in UK and Irish dental hospitals. Br Dent J 2021:10.1038/s41415-021-3330-3. [PMID: 34489545 DOI: 10.1038/s41415-021-3330-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Accepted: 09/09/2020] [Indexed: 11/08/2022]
Abstract
Aim To identify glove usage within UK and Ireland dental hospitals as well as the use of latex- and non-latex-containing dental equipment.Method A self-completed questionnaire was disseminated to 16 dental hospitals in the summer of 2017. The survey concerned their current use of latex and non-latex gloves and dental equipment. In addition, information was sought regarding any problems associated with non-latex and latex gloves.Results The questionnaire response rate was 13/16 (81%), of which 100% reported the use of non-latex examination gloves. The majority were using nitrile gloves. Twelve of the 13 dental hospitals would use examination gloves for simple extractions and 11 would use sterile gloves for minor oral surgery. In ten hospitals (77%), the sterile gloves were always non-latex, and again, the majority were nitrile. Latex-containing dental equipment including orthodontic bands, prophylactic polishing cups and dental dam was still being used within some dental hospitals, but to a much lesser extent than non-latex.Conclusion All dental hospitals were using latex-free examination gloves and were showing a move towards latex-free dental equipment. This usage is comparable to what has been seen in general dental practice and follows the trend towards latex-free dentistry.

Abstract
The nationwide opioid crisis continues to affect not only people who use opioids but also communities at large by increasing the risk of accidental occupational exposure to illicit opioids. In addition, the emergence of highly potent synthetic opioids such as fentanyl and carfentanil increases the need to protect workers who may encounter unknown drug substances during job activities. To support the National Institute for Occupational Safety and Health Opioids Research Gaps Working Group, we examined the state of the literature concerning methods to protect workers against accidental occupational exposure to illicit opioids, and have identified unmet research needs concerning personal protective equipment, decontamination methods, and engineering controls. Additional studies are needed to overcome gaps in technical knowledge about personal protective equipment, decontamination, and control methods, and gaps in understanding how these measures are utilized by workers. Increasing our knowledge of how to protect against exposure to illicit opioids has the potential to improve occupational health across communities.

Abstract
OBJECTIVE To compare perforation rates between tri-layer nitrile-latex and natural rubber latex surgical gloves after single-layer end-to-end jejunojejunal anastomoses in equine cadavers. STUDY DESIGN Prospective randomized ex-vivo study. SAMPLE POPULATION Pairs of surgical gloves (n = 46) worn during jejunojejunal anastomoses. METHODS Tri-layer nitrile-latex and rubber latex pairs of gloves were equally but randomly allocated to a right-handed surgeon performing 46 single-layer end-to-end jejunojejunal anastomoses on cadaveric material. Number and location of perforations were determined with the water leak test after each procedure. Ten unused pairs of both glove types were tested as controls. RESULTS At least one perforation occurred in 41% (19/46) of the pairs of gloves. Glove perforations were present in 22% (5/23; 95% CI: 9-42) of tri-layer glove pairs and 61% (14/23; 95% CI: 41-78) of the rubber glove pairs. The odds of glove perforation were 5.6 times (p = .009, 95% CI: 1.5-20.5) lower when tri-layer rather than rubber gloves were used. The duration of procedure did not affect the risk of glove perforation (p = .679). No perforations were observed in the unused gloves. CONCLUSION Perforations were less common when the surgeon wore tri-layer nitrile-latex gloves rather than to the natural rubber latex gloves tested in this study. CLINICAL RELEVANCE Tri-layer nitrile-latex gloves were more resistant to perforations in experimental settings; further studies may confirm that they are also superior in a clinical setting.

Abstract
INTRODUCTION The COVID-19 is a pandemic which has affected most people directly or indirectly. It being a communicable disease, the best way to control the disease is to prevent its spread. Lockdown in India has resulted in aesthetic practices all over the country being shut down indefinitely. As things return to normal, most aesthetic practitioners are looking forward to opening practices. Hence, there was a definite need for a consensus on how to safely open up practices in India and at the same time reassure patients coming into these clinics that their safety is paramount. METHODS This consensus guidelines use the PICO model in its structure. Five critical areas for opening up clinical establishments were identified and approached independently. A questionnaire was prepared using the modified Likert scale, and all the stakeholders were asked to answer the same. Any differences were then resolved with discussion among the stakeholders. The entire study was divided into five subgroups which were then analyzed in detail. RESULTS Key recommendations and consensus guidelines were made after detailed analysis. Handy flow diagram reviews of these key areas have been provided. A thorough review of literature was also done on each of the critical areas and recommendations incorporated wherever feasible. CONCLUSION These recommendations have considered the difficulties and cultural issues faced by aesthetic practices in India. They are user friendly, easy to understand and implement. These guidelines would help in reassuring practices to open up safely and continue serving patients with utmost care. LEVEL OF EVIDENCE Level V, Consensus guidelines.

Abstract
The present state of reproductive and sexual health around the world reveals disparities in contraceptive use and effectiveness. Unintended pregnancy and sexually transmitted infection transmission rates remain high even with current prevention methods. The 20th century saw a contraceptive revolution with biomedical innovation driving the success of new contraceptive technologies with central design concepts and materials. Current modalities can be broadly categorized according to their mode of function: reversible methods such as physical/chemical barriers or hormonal delivery devices via systemic (transdermal and subcutaneous) or localized (intrauterine and intravaginal) administration, and nonreversible sterilization procedures such as tubal ligation and vasectomy. Contraceptive biomaterials are at present dominated by well-characterized elastomers such as polydimethylsiloxane and ethylene vinyl acetate due to their favorable material properties and versatility. Contraceptives alter the normal function of cellular components in the reproductive systems to impair fertility. The purpose of this review is to highlight the bioengineering design of existing methods, explore novel adaptations, and address notable shortcomings in current contraceptive technologies.

Abstract
Objectives To evaluate the current routine use of latex gloves and latex containing dental dam in UK general dental practice. Methods A questionnaire was disseminated to 89 general dental practitioners (GDPs) in June 2017. The survey concerned their current, routine use of latex gloves and latex-containing dental dam in general dental practice. In addition, monthly sales figures of gloves classified by material, were obtained from a UK dental supply company, for 2015–2017. Results The questionnaire response rate was 84 (94%), of whom 90% reported using non-latex (non-sterile examination) gloves for their routine dentistry. The majority were using nitrile gloves. All GDPs surveyed would use examination gloves for routine extractions, and 76% would use examination gloves for surgical extractions. The majority (75%) reported using non-latex dental dam. Sales of nitrile gloves were significantly higher than for latex gloves, with a continuing trend in the reduction in volume of sales of latex gloves. Conclusion The majority of GDP's now routinely use non-latex containing gloves and dental dam in their clinical dentistry. Nitrile gloves are predominantly used. Examination gloves are used for straightforward extractions, with many practitioners also using them for minor oral surgery. Sales of latex containing gloves are continuing to decrease. Clinical significance The routine use of latex-containing products in UK dental practice is low and likely to reduce further, with on-going benefit for the dental practitioner, latex allergic patients and prevalence of latex allergy in the general population.

Abstract
BACKGROUND Medical examination gloves and surgical gloves protect the wearer directly and the patient indirectly from the risk of contamination. Because of concerns related to latex allergy, an increasing trend toward the use of synthetic gloves made of materials other than latex is observable. However, currently it is unknown if the physical properties of different materials may influence bacterial passage in case of a glove puncture. METHODS We examined 9 different medical examination gloves from various manufacturers made of nitrile (n = 4), latex (n = 3), or neoprene (n = 2). Additionally, 1 latex surgical glove each with and without antibacterial chlorhexidine gluconate coating and 1 synthetic surgical glove made of thermoplastic elastomer were included in the experiments. The studied materials were perforated following a standardized procedure, and direct bacterial passage was measured under dynamic conditions. Glove elasticity at 1 cm up to 2.5 cm elongation was measured following EN 455-2. RESULTS Nitrile gloves demonstrated higher material stiffness compared with latex gloves. Medical examination gloves made of nitrile and neoprene showed a 10-fold higher bacterial passage through a standardized puncture compared with latex gloves. All surgical gloves showed a lower bacterial passage compared with the tested examination gloves. CONCLUSION Bacterial passage through punctures is correlated with the stiffness or elasticity of the glove material. Therefore, gloves made of latex may have an increased protective effect in case of a glove breach. Whenever gloves are purchased and selected, a risk-benefit assessment should be conducted, balancing the risk of allergy against the degree of required protection in case of a glove puncture.

Abstract
BACKGROUND The use of examination gloves is part of the standard precautions to prevent medical staff from transmission of infectious agents between patients. Gloves also protect the staff from infectious agents originating from patients. Adequate protection, however, depends on intact gloves. The risk of perforation of examination gloves is thought to correlate with duration of wearing, yet, only very few prospective studies have been performed on this issue. METHODS A total number of 1500 consecutively used pairs of examination gloves of two different brands and materials (latex and nitrile) were collected over a period of two months on two ICU's. Used gloves were examined for micro perforations using the "water-proof-test" according to EN 455-1. Cox-regression for both glove types was used to estimate optimal changing intervals. RESULTS Only 26% of gloves were worn longer than 15 min. The total perforation rate was 10.3% with significant differences and deterioration of integrity of gloves between brands (p<0.001). Apart from the brand, "change of wound dressing" (p = 0.049) and "washing patients" (p = 0.001) were also significantly associated with an increased risk of perforation. CONCLUSION Medical gloves show marked differences in their durability that cannot be predicted based on the technical data routinely provided by the manufacturer. Based on the increase of micro perforations over time and the wearing behavior, recommendations for maximum wearing time of gloves should be given. Changing of gloves after 15 min could be a good compromise between feasibility and safety. HCWs should be aware of the benefits and limitations of medical gloves. To improve personal hygiene hand disinfection should be further encouraged.

Abstract
There is increasing concern that continued exposure to latex products can predispose individuals, particularly those who are atopic (allergy prone), to latex allergy. Latex allergy as a serious hazard has been well documented in the health care industry. There are also well-documented cases of food handlers who have had allergic reactions after the use of latex gloves. The contamination of food with latex proteins by food handlers using latex gloves can also result in potentially severe allergic reactions in latex-allergic consumers. We review latex allergy and present the case for avoiding latex glove use by food handlers in the food and hospitality industries. Adopting the use of nonlatex gloves has benefits for workers, consumers, and the food industry.
