Use Of Chlorhexidine Research Articles

Effect of chloramine T and chlorhexidine in reducing gingivitis in patients admitted to a reference hospital for cardiopulmonary care: a randomized, controlled clinical trial.

The aim of this study is to evaluate the effect of Chloramine T in reducing gingivitis in hospitalized patients, in addition to providing an alternative to the use of Chlorhexidine. A randomized, triple-blind, placebo controlled clinical trial was performed with 45 volunteers presenting with gingivitis, using the Löe Gingival Index (LGI). Patients were randomly allocated into one of three groups: (G1): Chloramine T 0.2%; (G2): Chlorhexidine 0.12% and (G3): distilled water. After five days, the control group (G3) remained without relevant differences in relation to the first pre-treatment assessment, while the groups tested with chlorhexidine and chloramine T showed improvement in the LGI (p < 0.05). After ten days, G3 maintained the results of the previous assessments, G1 repeated the five-day assessment and G2 obtained a statistically significant difference, with a better result in relation to the previous assessment (p < 0.05). After fifteen days, G3 showed no differences in relation to the other assessments, G1 had a statistically significant difference, showing better performance in relation to the previous assessment and G2 continued the gradual improvement it had been showing in the LGI (p < 0.05). Chloramine T and Chlorhexidine present similar results in the treatment of gingivitis, when evaluated by probing by the LGI, and Chloramine T can be used effectively, without causing the adverse effects inherent to prolonged use of chlorhexidine. Importance of oral hygiene for patients admitted to hospitals with the use of adjuvant substances that do not present adverse effects such as chlorhexidine, which is considered the gold standard, seeking to provide better clinical protocols.

Association of umbilical cord care practices with neonatal infection in Katsina, northwest Nigeria

Background: Significant numbers of neonatal deaths occurring each year are caused by infections that can be directly associated with improper and unhygienic umbilical cord care practices. The objectives of this study were to describe the umbilical cord care practices among mothers whose babies were admitted for suspected sepsis at the Federal Teaching Hospital and Turai Umaru Yar’adua Maternal and Children Hospital Katsina, Nigeria, assess the relationship between umbilical cord care practices and neonatal sepsis, and the influence of home delivery on this relationship. Methodology: This was a hospital-based descriptive observational study of 60 selected neonates with clinical features of sepsis admitted into the special care baby unit (SCBU) of the two hospitals between July and December 2022. The study involved the collection and microbiological analysis of blood samples using the BacT/Alert microbial detection system, and the administration of a structured questionnaire on the mother of each enrollee to collect relevant information about cord care practices. Data were analyzed using SPSS version 22.0. The Chisquare (x2) test and Odds ratio (with 95% confidence interval) were used to determine the association of risk factors with culture-confirmed sepsis, and a p value less than 0.05 was considered statistically significant. Results: Of the 60 neonates blood samples, 31 (51.7%) were culture-positive for neonatal sepsis while 29 (48.3%) were culture-negative. There was no statistically significant association between risk factors such as application of traditional materials for cord care and place of delivery, and culture-confirmed neonatal sepsis (p&gt;0.05). However, neonates whose mothers use traditional materials for cord care were more likely to develop sepsis than those who do not (OR=2.027, 95% CI=0.716-5.736). Concerning place of delivery, which is an important determinant of umbilical cord hygiene, babies delivered at home were almost 3 times more likely to have culture-confirmed sepsis than those delivered in the hospital (OR=2.975, 95% CI=1.040-8.510). A total of 26 out of the 60 (45.3%) mothers of the neonates agreed to have used unhygienic and traditional materials for cord care, with charcoal (39.0%), local herbs (27.0%), cow dung/urine concoction (19.0%), and others (15.0%), such as lubricants, ash, and balm, being the most commonly used materials for cord care. Conclusion: Neonatal infection is common among newborns in Federal Teaching Hospital and Turai Umaru Yar’adua Maternal and Children Hospital (TUYMCH), Katsina, northwest Nigeria, with a prevalence of culture-confirmed neonatal sepsis of 51.7%. Although there was no statistically significant association between unhygienic cord practices and neonatal sepsis in this study, babies whose mothers use traditional materials for cord care were more likely to develop sepsis. There is a high rate of use of harmful and unhygienic traditional materials for cord care in our environment. This habit can be discouraged through health education using the mass media and health talks in health facilities. The use of chlorhexidine, the recommended antiseptic for cord care by the World Health Organization and the Nigeria Federal Ministry of Health, should be encouraged.

Intravitreal chlorhexidine for sterilizing the vitreous cavity in an animal model of bacterial endophthalmitis

Purpose To evaluate the efficacy and safety of intravitreal chlorhexidine (CHX) for sterilising the vitreous cavity in bacterial endophthalmitis. Methods For in-vitro experiments, full-thickness retina explants were harvested from freshly enucleated pig eyes. Six-millimeter circular sensory retina patches were then incubated in varying concentrations of CHX (0.625-800 µg/mL) for 24 hours. Retinal cell viability was determined at the end of the incubation period with a live-dead assay. The bactericidal effects of the tested CHX concentrations were determined using a quantitative suspension test on Staphylococcus epidermidis. The safety of CHX was also tested by injecting varying doses of CHX (50-400 µg/mL) into the vitreous cavity of albino rabbits followed by flash electroretinography (ERG) and light microscopy. The bactericidal effect of the non-toxic CHX doses was determined using the rabbit model of endophthalmitis created by injecting 3000 CFU/0.1 mL of Staphylococcus epidermidis. Results In vitro concentrations of CHX greater than 6.25 µgr/mL exerted a bactericidal effect, while concentrations of CHX less than 200 µg/mL did not impair retinal cell viability. Intravitreal concentrations of CHX between 20-100 µg/mL were adequate to sterilise the infected rabbit vitreous cavity in the animal model. No significant functional or anatomical deleterious effect was observed with ERG or light microscopy. Conclusion CHX can sterilise the vitreous cavity in an animal model of bacterial endophthalmitis without impairing retinal cell viability. Our results encourage further research for clinical use of chlorhexidine in treatment of bacterial endophthalmitis.

Advances in the use of chlorhexidine for periodontitis treatment in diabetic patients: A review.

Periodontitis and diabetes mellitus exhibit a bidirectional relationship. This narrative review descriptively outlines the role of chlorhexidine in the periodontal treatment of diabetic patients, focusing on its antimicrobial mechanisms against microbial communities and its antiplaque effects. Although chlorhexidine is proven to be effective in combating microbial presence and improving gingivitis with substantial supporting evidence, its impact on glycemic control and insulin resistance in diabetic patients remains contentious. Additionally, the effectiveness of chlorhexidine as an adjunctive chemotherapeutic in the periodontal treatment of gestational diabetes has not yet been studied, highlighting a gap in research that necessitates further prospective studies and randomized controlled trials. Considering the interconnection between periodontal inflammation and glycemic levels, this article finally advocates for collaborative care between dental and medical professionals to manage periodontitis in diabetic patients effectively.

The Effect of Chlorhexidine Gluconate Mouthwash in Comparing OHI-S Scores in Students of the Karya Adi Husada Mataram Dental Health Academy

The overall health of the body includes oral and dental health. The aftereffects of the 2018 Riskesdas show that most of the Indonesian populace (94.7%) has great tooth brushing propensities, specifically they have carried out the way of behaving of cleaning their teeth consistently. Sadly, however, only 2.8% of this number brush their teeth correctly, at least twice per day—in the morning after breakfast and at night before bed. The use of chlorhexidine as a mouthwash is a periodontal treatment because it has antiseptic properties, inhibiting plaque formation. The aim of this study was to determine the difference between gargling using Chlorhexidine Gluconate after brushing your teeth and not rinsing your mouth. The research process was carried out at the Karya Adi Husada Mataram Dental Health Academy and was carried out by observing samples between those who gargled using Chlorhexidine gluconate and those who did not gargle. The research results show significant results in the univariate analysis statistical test, namely from the results of statistical tests using the univariate analysis test, the count is 85,154 tables with α0.05, which is 14,6114, meaning the count is greater than the table so Ho is rejected. So it can be concluded that there is a difference in OHIS values ​​between those who gargle Chlorhexidine gluconate and those who do not gargle Chlorhexidine gluconate, where the OHIS value of Chlorhexidine gluconate mouthwash users is better than the OHIS value of students who do not gargle Chlorhexidine gluconate.

Sustainability of Surgical Site Infection (SSI) Prevention Bundle for Pediatric Cardiothoracic Surgery Patients

Background: Frequent use of delayed sternal closure and prolonged stays in critical care units contribute to surgical site infections among pediatric patients undergoing cardiothoracic (CT) procedures. Bundled interventions to prevent or reduce surgical site infections (SSIs) have shown prior success, but limited data exist on sustainability of these efforts especially during the Coronavirus Disease 2019 (COVID-19) pandemic. Here, we re-examine the SSI rates for pediatric CT procedures after the onset of the pandemic. Methods: In a single academic center providing regional quaternary care, we created a multidisciplinary CT-surgery SSI Prevention workgroup in response to rising CT SSI rates. Bundle elements focused on daily chlorhexidine bathing, environmental cleaning, monthly room changes, linen management, antimicrobial prophylaxis, and sterile techniques for beside and operating room procedures. CDC surveillance definitions were used to identify superficial, deep or organ space SSIs. To assess the bundle’s sustainability, we compared SSI rates during years impacted by the COVID-19 pandemic (2021–2023, period 2) to pre-pandemic rates (2017–2019, period 1). Data from 2020 were excluded to account for bundle implementation, pandemic restrictions, and a minor decrease in surgical volumes. Rates were calculated as surgical site infection cases per 100 procedures. Mean rates across both periods were compared using paired t-tests (Stata/SE version 14.2). Results: Excluding the year 2020, the average SSI rate per 100 CT procedures increased from 1.07 in period 1 to 1.56 in period 2(p=0.55). Concurrently, the average SSI rate per 100 CT procedures with delayed closures increased from 1.49 in period 1 to 1.97 in period 2(p=0.67). Figure 1 shows SSI rates and procedure counts for 2017–2023. Coagulase negative Staphylococci most frequently caused SSIs in period 1 while methicillin-susceptible Staphylococcus aureus (MSSA) was most frequently identified in period 2. During period 2, the estimated compliance with SSI prevention bundle remained stable and reached 95% for pre-operative chlorhexidine baths and use of appropriate antimicrobial prophylaxis. Monthly room changes with dedicated environmental cleaning reached 100% compliance. Conclusion: Despite staffing shortages and resource limitations (e.g., discontinuation of contact isolation for MRSA colonization) during the COVID-19 pandemic, SSI rates for pediatric CT surgeries showed a slight, but non-statistically significant, increase in post-pandemic years as compared to pre-pandemic years. implementation of bundled interventions and improved surveillance methods may have sustainably impacted these SSI rates. Reinforcing bundle adherence as well as identifying additional prevention interventions to incorporate in pre-, intra-, and post-operative periods may improve patient outcomes.

The Impact of Chlorhexidine as an Endodontic Irrigant/Medicament on Post-Obturation Pain in Patients Following Endodontic Therapy: A Preliminary Bayesian Meta-Analysis.

To assess the overall impact of chlorhexidine, when used as an endodontic irrigant/medicament, on post-obturation pain following endodontic treatment by the application of Bayes methods of meta-analysis. This study aimed to combine recently documented evidence using rigorous and specific search criteria. The available data were analyzed using Bayesian methods, which have the advantage of accounting for uncertainties in estimates. This is in contrast to commonly used frequentist meta-analysis methods, which are not able to model uncertainties as effectively, particularly when there is heterogeneity present. A preliminary search was conducted in the Pubmed, Cochrane, and Scielo databases using appropriate keywords. The search aimed to identify human randomized clinical studies that evaluated post-operative endodontic pain and involved the use of chlorhexidine as an endodontic irrigant or medicament. The preliminary Bayesian meta-analysis produced a more accurate estimate compared to a frequentist random effect meta-analysis model, with a narrower credible interval. The frequentist model demonstrated a detrimental impact of chlorhexidine on post-obturation pain, while the Bayesian model indicated a somewhat favorable effect of chlorhexidine on post-obturation pain. Based on the scope of this investigation, it can be inferred that a Bayesian random effects meta-analysis model demonstrated a somewhat favorable impact of chlorhexidine on post-endodontic pain, which carries significant therapeutic significance.

National chlorhexidine coverage and factors associated with newborn umbilical cord care in Bangladesh and Nepal: a cross-sectional analysis using household data

BackgroundPreventable newborn deaths are a global tragedy with many of these deaths concentrated in the first week and day of life. A simple low-cost intervention, chlorhexidine cleansing of the umbilical cord, can prevent deaths from omphalitis, an infection of the umbilical cord. Bangladesh and Nepal have national policies promoting chlorhexidine use, as well as routinely collected household survey data, which allows for an assessment of coverage and predictors of the intervention.MethodsWe used data from the 2017–2018 Bangladesh Demographic and Health Survey and the 2016 Nepal Demographic and Health Survey, two large-scale nationally representative household surveys. We studied coverage of single application of chlorhexidine to the umbilical cord of newborns born in the past year using descriptive, bivariate and multivariable analyses. Key predictors of newborns receiving chlorhexidine cleansing, including socio-economic factors, healthcare related factors and the application of harmful and nonharmful substances, were explored in this study.ResultsCoverage of chlorhexidine cleansing was 15.0% in Bangladesh and 50.7% in Nepal, while the application of a harmful substance was 16.9% in Bangladesh and 22.6% in Nepal. Results from the multivariable analyses indicated that delivery in a health facility was strongly associated with a newborn’s receipt of chlorhexidine in both countries (Bangladesh: OR = 2.23, p = 0.002; Nepal: OR = 5.01, p = 0.000). In Bangladesh, delivery by Cesarean section and application of another non-harmful substance were significantly and positively associated with the receipt of chlorhexidine. In Nepal antenatal care was significantly and positively associated with chlorhexidine, while application of a harmful substance was significantly and negatively associated with receipt of chlorhexidine. Maternal education, urban/rural residence, religion and sex were not significant in the multivariable analysis. Wealth was not a significant factor in Bangladesh, but in Nepal newborns in the two highest wealth quintiles were significantly less likely to receive chlorhexidine than newborns in the lowest wealth quintile.ConclusionAs Bangladesh and Nepal continue to scale-up chlorhexidine for newborn umbilical cord care, additional focus on newborns born in non-facility environments may be warranted. Chlorhexidine cleansing may have the potential to be an equitable intervention, as newborns from the poorest wealth quintiles and whose mothers had less education were not disadvantaged in receiving the intervention in these two settings.

Efficacy of Chlorhexidine Impregnated Wipes for the Local Dysbiosis in Atopic Dogs: A Multicentric Prospective Study.

(1) Background: Dysbiosis is frequently observed in Canine Atopic Dermatitis (CAD). Antimicrobial treatment may be necessary to treat flare ups and the use of topical treatments is beneficial to prevent the development of bacterial resistance. Wipes are an easy way to apply antiseptic agents on the skin. The aim of this study was to evaluate the benefits of 3% chlorhexidine impregnated wipes (Pyoskin® wipes, MP Labo, France) on local areas of dysbiosis in dogs with CAD. (2) Methods: A total of 20 dogs suffering from CAD presented with localised areas of dysbiosis were included in this study. Affected areas were cleansed with the daily application of chlorhexidine wipes once a day for 14 days. Follow-up visits were scheduled after one and two weeks. Clinical signs (lesions and pruritus), dysbiosis scored by cytological counts (cocci and Malassezia) and investigator and owner global appreciation were evaluated. (3) Results: A statistically significant decrease in clinical scores and cytological counts were observed as soon as D7 and until D14. Both owner and investigator appreciation were considered high (4) Conclusions: The use of chlorhexidine impregnated wipes is a useful and easy way to manage localised dysbiosis in atopic dogs and allows limiting of systemic medication to prevent bacterial resistance.

Oral care practices for patients in intensive care unit: A systematic review.

To critically analyse and discuss oral hygiene protocols in the hospital environment in patients admitted to the ICU, through a systematic review of the literature. The electronic search was performed on Pubmed, Cochrane, Web of Science and Google Scholar databases. The indexing keywords according to the PRISMA protocol were: 'hospital dentistry', 'oral health', 'oral care' and 'intensive care unit'. The initial search resulted in a total of 2671 articles. Pre-selection based on titles led to the exclusion of 2510 articles and the remaining 36 were selected for abstract reading. After analysing the eligibility of the articles, eight studies were included in the review and submitted to qualitative analysis. It can be concluded that cleaning with a soft bristle brush, use of chlorhexidine and lip moisturizing are methods commonly used in dental care actions in patients hospitalized in intensive care units.

Impact of postoperative skin disinfection with chlorhexidine on bacterial colonisation following shoulder arthroplasty surgery: a controlled randomised study

Surgical site infections are a significant threat to patient safety. Shoulder arthroplasty carries an increased risk due to foreign implants. Skin preparation in general is a key preoperative preventive intervention, and the use of chlorhexidine can have a prolonged effect on bacterial colonisation. There is a lack of evidence regarding whether postoperative disinfection has an impact on bacterial colonisation during the first 48 hours after surgery. Our hypothesis was that applying postoperative antiseptic with 5 mg/ml chlorhexidine in 70% ethanol would lead to reduced bacterial colonisation with Staphylococcus aureus, coagulase-negative staphylococcus and Cutibacterium acnes around the surgical wound within the initial 48 hours after elective shoulder surgery, compared with the use of sodium chloride. A single-blinded, controlled study was conducted at a county hospital in Sweden. Swabs from the skin were collected four times: at baseline, preoperatively, after the intervention and after 48 hours. Our hypothesis was not confirmed. Although not statistically significant, the chlorhexidine group had a higher prevalence of bacterial colonisation of clinically relevant bacteria. Our study could not confirm that postoperative disinfection with chlorhexidine reduces bacterial colonisation compared with sodium chloride. The results highlight the complexity of SSIs and the importance of evidence-based preventive skin preparation to ensure patient safety. Further research is needed, considering the study's limitations, to explore and evaluate the effectiveness of different skin cleansing solutions and preventive strategies in diverse surgical contexts.

Essential Oils from the Perspective of Dentistry

Introduction: With a significant increase in interest in recent years regarding essential oils, the purpose of this work was to identify how Dentistry has researched and utilized these substances through an integrative review of articles available in indexed databases. The bibliographic survey was conducted in November and December 2022, through electronic research, consulting the Pubmed and LILACS databases. The descriptors and boolean operators used were: "volatile oils" OR "essential oils" AND "dentistry". The material published between 2018 and 2022 indexed in the mentioned databases and with a free version was included. Studies that did not address the proposed study theme were excluded. Material and Method: Out of 104 scientific articles found, 29 studies were reviewed and analyzed. Result and Discussion: A variety of plant derivatives have been studied for their inhibitory effect on C. albicans biofilms and for cytotoxicity, several are considered promising for the development of future research and bioproducts applicable to human health. Clinical studies indicated that the EOs from Pelargonium graveolens and Zataria multiflora are potentially effective in treating oral candidiasis, and the most promising EOs were obtained from Allium tubeorosum, Cinnamomum cassia, Cinnamomum zeylanicum, and Coriandrum sativum L. Further non-clinical and clinical studies with these EOs are necessary to determine their potential use and safety for the treatment of oral candidiasis. Listerine mouthwash was often compared with other chemical agents, mainly chlorhexidine, which in terms of plaque control is considered the gold standard in efficacy and substantivity. However, the use of chlorhexidine has disadvantages like altered taste sensations, teeth discoloration. With all this, the World Health Organization (WHO) recommended that researchers analyze the use of natural products, such as extracts of herbs and plants, to combat these negative effects. In another randomized study, they concluded that the mouthwash containing aqueous extracts of essential oils was as effective antibacterial agents as chlorhexidine mouthwashes, corroborating with other descriptive and experimental studies. Conclusion: The articles demonstrated extensive study regarding essential oils in Dentistry, presenting various applications that are still being explored: they have potential in the development of preventive or therapeutic agents for various oral diseases, use in dental materials, and popular applications. There is still a need for more clinical trials to establish safety and efficacy in oral health due to the wide variety of existing essential oils.

Effect of Maternal and Newborn Care Service Package on Perinatal and Newborn Mortality

In resource-constrained settings where the neonatal mortality rate (NMR) is high due to preventable causes and health systems are underused, community-based interventions can increase newborn survival by improving health care practices. To develop and evaluate the effectiveness of a community-based maternal and newborn care services package to reduce perinatal and neonatal mortality in rural Pakistan. This cluster randomized clinical trial was conducted between November 1, 2012, and December 31, 2013, in district Rahim Yar Khan in the province of Punjab. A cluster was defined as an administrative union council. Any consenting pregnant resident of the study area, regardless of gestational age, was enrolled. An ongoing pregnancy surveillance system identified 12 529 and 12 333 pregnancies in the intervention and control clusters, respectively; 9410 pregnancies were excluded from analysis due to continuation of pregnancy at the end of the study, loss to follow-up, or miscarriage. Participants were followed up until the 40th postpartum day. Statistical analysis was performed from January to May 2014. A maternal and newborn health pack, training for community- and facility-based health care professionals, and community mobilization through counseling and education sessions. The primary outcome was perinatal mortality, defined as stillbirths per 1000 births and neonatal death within 7 days per 1000 live births. The secondary outcome was neonatal mortality, defined as death within 28 days of life per 1000 live births. Systematic random sampling was used to allocate 10 clusters each to intervention and control groups. Analysis was conducted on a modified intention-to-treat basis. For the control group vs the intervention group, the total number of households was 33 188 vs 34 315, the median number of households per cluster was 3092 (IQR, 3018-3467) vs 3469 (IQR, 3019-4075), the total population was 229 155 vs 234 674, the mean (SD) number of residents per household was 6.9 (9.5) vs 6.8 (9.6), the number of males per 100 females (ie, the sex ratio) was 104.2 vs 103.7, and the mean (SD) number of children younger than 5 years per household was 1.0 (4.2) vs 1.0 (4.3). Altogether, 7598 births from conrol clusters and 8017 births from intervention clusters were analyzed. There was no significant difference in perinatal mortality between the intervention and control clusters (rate ratio, 0.86; 95% CI, 0.69-1.08; P = .19). The NMR was lower among the intervention than the control clusters (39.2/1000 live births vs 52.2/1000 live births; rate ratio, 0.75; 95% CI, 0.58-0.95; P = .02). The frequencies of antenatal visits and facility births were similar between the 2 groups. However, clean delivery practices were higher among intervention clusters than control clusters (63.2% [2284 of 3616] vs 13.2% [455 of 3458]; P < .001). Chlorhexidine use was also more common among intervention clusters than control clusters (55.9% [4271 of 7642] vs 0.3% [19 of 7203]; P < .001). This pragmatic cluster randomized clinical trial demonstrated a reduction in NMR that occurred in the background of improved household intrapartum and newborn care practices. However, the effect of the intervention on antenatal visits, facility births, and perinatal mortality rates was inconclusive, highlighting areas requiring further research. Nevertheless, the improvement in NMR underscores the effectiveness of community-based programs in low-resource settings. ClinicalTrials.gov Identifier: NCT01751945.

Effectiveness of nanoparticle-based antimicrobial agents in the prevention and treatment of Central Venous Catheter-Associated Bloodstream Infections

Background In healthcare settings, Central Venous Catheter-Associated Bloodstream Infections (CVC-BSIs) present a serious problem since they raise morbidity, mortality, and medical expense rates. The management of these illnesses is made more challenging by the development of antimicrobiotic resistance. Nanotechnology has attracted interest recently as a viable method for creating new antimicrobial agents. By putting antibacterial nanomaterials onto the catheter’s appear, that may reduce the likelihood of getting sick by stopping germs from adhering and growing. Antimicrobial additives can be released gradually finishes, protecting over time through bioengineering sectors. To prevent and treat CVC-BSIs, this study will assess the efficacy of antimicrobial medicines based on nanoparticles. Methods In the network Meta-Analyses (MA) and Systematic Review (SR), we looked for studies published from January 2010 to September 2021 using the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, MEDLINE, CINAHL, and Web of Science databases. Ten papers in all were included in the review following the screening of the publications using inclusion and exclusion criteria. Results In contrast to conventional catheters, the implementation of Antimicrobial Catheters (AC) and the use of chlorhexidine (CHG) or Silver Sulfadiazine (SS) demonstrated notably reduced occurrences of Central Venous Catheter-Associated Bloodstream Infections (CVC-BSIs) per 1000 Catheter Days (CD) (with Odds Ratios (ORs) and 95% Credibility Intervals (CrIs) of 0.66 and 0.54, respectively) by bioengineering sectors. Moreover, these interventions were linked to the lowest rate of Catheter Colonization (CC), with ORs as well as 95% CrIs of 0.45 and 0.31, respectively, underscoring their potential as effective strategies for minimizing the risk of infections associated with catheter use as well as bioengineering sectors innovations. Conclusions As a result, CVC-BSI has shown significant promise for prevention and treatment with nanoparticle-based antimicrobial medicines. Due to their special characteristics and modes of action, they are strong candidates for improving the security and effectiveness of central venous catheter use in clinical settings. Due to ongoing research and development in this area, nanoparticle-based coatings and therapies may be used to lessen the impact of CVC-BSIs and enhance patient outcomes.

Use of ClearGuard HD caps in pediatric hemodialysis patients

BackgroundBloodstream infections (BSIs) are a leading cause of hospitalizations and mortality among patients receiving hemodialysis (HD) therapy, especially those with a central venous catheter (CVC) for dialysis access. The use of chlorhexidine impregnated catheter caps (ClearGuard) has been associated with a decrease in the rate of HD catheter-related BSIs (CA-BSIs) in adults; similar data have not been published for children.MethodsWe compared CA-BSI data from participating centers within the Standardizing Care to Improve Outcomes in Pediatric Endstage Kidney Disease (SCOPE) collaborative based on the center’s use of ClearGuard caps for patients with HD catheter access. Centers were characterized as ClearGuard (CG) or non-ClearGuard (NCG) centers, with CA-BSI data pre- and post-CG implementation reviewed. All positive blood cultures in participating centers were reported to the SCOPE collaborative and adjudicated by an infectious disease physician.ResultsData were available from 1786 SCOPE enrollment forms completed January 2016–January 2022. January 2020 served as the implementation date for analyzing CG versus NCG center data, with this being the time when the last CG center underwent implementation. Post January 2020, there was a greater decrease in the rate of HD CA-BSI in CG centers versus NCG centers, with a decrease from 1.18 to 0.23 and 0.41 episodes per 100 patient months for the CG and NCG centers, respectively (p = 0.002).ConclusionsRoutine use of ClearGuard caps in pediatric dialysis centers was associated with a reduction of HD CA-BSI rates in pediatric HD patients.Graphical abstractA higher resolution version of the Graphical abstract is available as Supplementary information

Bacterial contamination of air and surfaces during dental procedures-An experimental pilot study using Staphylococcus aureus.

The oral cavity contains numerous microorganisms, including antimicrobial-resistant bacteria. These microorganisms can be transmitted via respiratory particles from patients to healthcare providers and vice versa during dental care. We evaluated the spread of Staphylococcus aureus during standardized dental procedures using different scaling devices and rinsing solutions. During systematic therapy for dental biofilm removal (guided biofilm therapy), using an airflow or ultrasound device to a model simulation head. Staphylococcus aureus suspension was injected into the mouth of the model to mimic saliva. Different suction devices (conventional saliva ejector or a prototype) and rising solutions (water or chlorhexidine) were used. To assess contamination with S. aureus, an air-sampling device was placed near the oral cavity and samples of surface areas were collected. S. aureus was only detected by air sampling when the conventional saliva ejector with airflow was used. No growth was observed during treatments with the ultrasonic piezo instrument or the prototype suction device. Notably, a rinsing solution of chlorhexidine digluconate decreased the bacterial load compared to water. Surface contamination was rarely detected (1 of 120 samples). Although our findings indicate potential airborne bacterial transmission during routine prophylactic procedures, specific treatment options during biofilm removal appear to reduce air contamination. These options include ultrasonic piezo devices or the prototype suction device. The use of chlorhexidine reduced the CFU counts of S. aureus detected by air sampling. Surface contamination during dental procedures was a rare occurrence.

Effectiveness of Chlorhexidine and Povidone Iodine in Preventing Surgical Site Infections (SSIs) in C-Section Deliveries

Objective: To compare the effectiveness of Chlorhexidine and Povidone iodine in preventing SSIs in C-section deliveries. Methodology: The study was conducted at a medical university and hospital in Karachi, from January 2021 July 2021. A non-probability consecutive sampling technique was used to select 35 participants. The study included women aged 18 to 45 years. The efficacy of Chlorhexidine and Povidone iodine in preventing SSIs was evaluated. Two groups were randomly assigned, with Group 1 receiving Chlorhexidine gluconate and Group 2 receiving Povidone-Iodine for skin preparation. Data on various factors were recorded, and the occurrence of SSIs within ten days of cesarean delivery was assessed. Results: The study included women aged 18 to 45 years. The efficacy of Chlorhexidine and Povidine iodine in preventing SSIs was evaluated. The results showed that Chlorhexidine was effective in preventing SSIs in 94.3% of cases, while Povidone iodine was effective in 91.4% of cases. However, no significant difference was observed between the two groups. The study results were consistent with previous research showing a reduction in SSI rates with the use of Chlorhexidine or Povidone- iodine. The overall rate of SSI was lower in the Chlorhexidine group, but contextual factors and adherence to infection control practices may influence outcomes. Conclusion. This study augments existing knowledge on preventing SSIs in C-section deliveries. While both Chlorhexidine and Povidone-iodine demonstrated comparable efficacy, Chlorhexidine appeared slightly more effective in reducing SSIs. Nonetheless, the study's limitations underscore the necessity for further research in diverse healthcare settings.

Uncovering the Benefits of Povidone Iodine Compared to Other Therapeutic Agents in Wound Infection Prevention and Healing Outcomes: A Scoping Review.

The selection of an appropriate chemical solution in wound care reduces the severity of wounds and accelerates the healing process. Povidone-iodine (PV-I), a chemical solution popularly known as an antiseptic, is frequently used in studies of wound care to prevent wound infection and accelerate woud the process of wound healing. To identify the latest evidence on the benefits of PV-I in wound infection prevention and healing in all areas. This review is a scoping review by Arskey and O'Malley and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) is used for reporting. The literature search used databases including PubMed, CINAHL, and search engines such as Scopus. This study was conducted using thematic analysis. This review yielded 19 out of 2109 studies that were identified in the initial search. Four outcomes comprised 20 sub-outcomes have been identified. Although strong evidence is lacking, PV-I in the form of foam is effective in improving wound healing, shortening healing time, and producing fewer adverse events than hydrocelluers. Moreover, saline and PV-I are effective as skin disinfectants when compared to saline alone in reducing surgical site infection (SSI), and they are also more effective than hypochlorous acid in improving wound healing. Nevertheless, there was no difference between PV-I and hypochlorous acid in the prevention of SSI and bacterial growth. In terms of healing time, silver foam and hyaluronic acid were more favorable than PV-I. Moreover, the use of chlorhexidine to improve SSI and silver dressing to improve hospital stay is more favorable than that of PV-I. There is limited evidence regarding the effectiveness of wound care outcomes, and the efficacy of PV-I as a surface disinfectant for wound infectionprevention remains controversial. Consequently, PV-I is not highly recommended for wound care, and further investigation into the effectiveness of PV-I as a surface disinfectant is required for various types of surgeries.

EFFECT OF SPERMININE AND ITS COMBINATION WITH SPERMINOXIDASE INHIBITORS ON THE PROFILE OF POLYAMINE AND SURVIVAL OF HUMAN PROSTATE CANCER CELLS

Summary. Aim: to investigate the effect of spermine (Spn) and spermine oxidase inhibitors (SMO) and their effect in combination on the polyamine profile in human PCa cell lines and to compare the nature of polyamine changes with tumor cell viability. Object and methods: the study was performed on cell cultures of hormone-sensitive (LNCaP) and hormone-resistant (DU-145) cell lines. The profile of polyamines in tumor cells and the activities of spermine oxidase and polyamine oxidase (PAO) were determined by high-performance liquid chromatography. Results: the addition of Spn to the culture medium causes a significant accumulation of this polyamine in cells, a decrease in putrescine (Put) and spermidine (Spd). The use of SMO inhibitors (chlorhexidine and MDL-72527) is accompanied by a decrease in Spd levels and accumulation of acetylated spermidine (AcSpd). The use of Spn leads to a decrease in the proliferation rate — the molar ratio of spermidine/spermine (Spd/Spn). Particularly low values of the Spd/Spn ratio were observed when spermine was used in combination with SMO inhibitors. When Spn was used in combination with SMO inhibitors, the lowest cell viability rates were also observed, indicating a more effective inhibition of cell growth with the combined use of these factors compared to their use separately, even in significantly higher concentrations. The use of chlorhexidine and chlorhexidine together with spermine led to a decrease in the activity of SMO and PAO. Conclusions: the use of spermine and spermine in combination with SMO inhibitors leads to changes in the polyamine profile in tumor cells characteristic of growth inhibition (decrease in Spd, Put and increase in Spn) and a decrease in the molar ratio Spd/Spn. These changes are accompanied by a decrease in the survival of cells of hormone-sensitive (LNCaP) and hormone-resistant (DU-145) human prostate cancer lines. The obtained results show the prospects for further study of spermine and its combination with SMO inhibitors as potential agents for the treatment of prostate cancer.

Characteristics of the pre-surgical preparation of the skin in surgical interventions

Introduction: The pre-surgical bath is indicated prior to any surgery. There are different preparation protocols, with the purpose of removing the bacteria and, thus, reducing the infection of the surgical wound. Objective: to describe the characteristics of the pre-surgical preparation carried out by the nursing staff in patients undergoing surgery at the Sirio Libanés Hospital in the Autonomous City of Buenos Aires. Materials and Methods: This study has a mixed approach, Observational, descriptive, non-experimental, cross-sectional design and prospective analysis. For the qualitative variables, non-participant observation was used for and a checklist with follow-up of postoperative patients for up to 72 hours, added to a Google Forms survey for the quantitative variable. Results: they indicated that 76.7% of professionals perform this procedure the same day of surgery and the most used antiseptic, with 57%, was 2% Chlorhexidine cloth, with 38% presenting surgical site infection. 90% of staff did not perform hair removal. The heterogeneity of skin preparation protocols and variable compliance rates makes it difficult to isolate preoperative preparation as the main determinant for infection prevention in surgical patients. Conclusion: currently, there is a lack of research on the influence of pre-surgical skin preparation, the use of chlorhexidine, hair removal and the value of the role of nursing staff, evidencing the importance of having protocols and constant staff training.
