OBJECTIVE: To investigate the potential mechanisms of sepsis pathogenesis in intensive care unit (ICU), with a specific focus on the role of skin microbiota, and to evaluate the causal relationships between skin microbiota and ICU sepsis using Mendelian randomization (MR). METHODS: A two-sample MR analysis was performed using skin microbiota genome-wide association study (GWAS) summary data from German population cohorts as exposures, combined with ICU sepsis susceptibility and 28-day mortality GWAS summary data from the IEU OpenGWAS database as outcomes. The primary causal effect estimates were generated using the inverse variance weighted (IVW) method, supplemented by validation through MR-Egger and weighted median approaches. Heterogeneity and pleiotropy tests, along with sensitivity analyses, were conducted to evaluate the robustness of the results. RESULTS: Regarding risk of ICU sepsis, IVW analysis showed that order Pseudomonadales [odds ratio (OR) = 0.93, 95% confidence interval (95%CI) was 0.88-0.98], family Flavobacteriaceae (OR = 0.93, 95%CI was 0.90-0.96), and genus Acinetobacter (OR = 0.96, 95%CI was 0.93-0.99) were significantly negatively correlated with the risk of ICU sepsis (all P < 0.05). There was a significant positive correlation between the risk of ICU sepsis and the presence of β-Proteobacteria (OR = 1.05, 95%CI was 1.00-1.11) and Actinobacteria (OR = 1.05, 95%CI was 1.00-1.11), both P < 0.05. Regarding 28-day mortality of ICU sepsis, IVW analysis showed that phylum Bacteroidetes (OR = 0.92, 95%CI was 0.86-0.99), family Streptococcaceae (OR = 0.92, 95%CI was 0.85-0.98), family Flavobacteriaceae (OR = 0.90, 95%CI was 0.83-0.97), genus Streptococcus (OR = 0.92, 95%CI was 0.86-0.99), ASV016 [Enhydrobacter] (OR = 0.92, 95%CI was 0.87-0.98), and ASV042 [Acinetobacter] (OR = 0.92, 95%CI was 0.88-0.97) were significantly negatively correlated with the 28-day mortality of ICU sepsis (all P < 0.05); family Moraxellaceae (OR = 1.09, 95%CI was 1.00-1.18) and ASV008 [Staphylococcus] (OR = 1.08, 95%CI was 1.03-1.14) was significantly positively correlated with the 28-day mortality of ICU sepsis (both P < 0.05). Sensitivity analysis and MR-PRESSO showed no heterogeneity, pleiotropy, or horizontal pleiotropy between skin microbiota and ICU sepsis risk and 28-day mortality rate. Analysis of confounding factors showed that single nucleotide polymorphisms (SNPs) associated with relevant skin bacteria could independently and causally affect the risk of ICU sepsis or ICU sepsis related mortality rate, independent of other confounding factors. The Steiger test results indicated that the established causal relationship was not due to reverse causality. CONCLUSIONS Skin microbiota composition may influence both sepsis susceptibility and 28-day mortality in ICU settings. Family Flavobacteriaceae demonstrated protective effects against sepsis onset and mortality. These findings provide new perspectives for early detection and management strategies.

BACKGROUND

A “rejuvenating set” is composed of different skin products. A dilemma is that these are readily available despite containing active ingredients subject to regulation. There are several reports of side effects from use of these products.

This study aimed to assess the knowledge, attitude, and practices on Rejuvenating sets among patients.

This is a descriptive and observational study. Respondents answered a questionnaire covering the patient’s age, sex, educational attainment, occupation, monthly income, marital status, consumer behavior and preference in selection, side effects, habits, and practices of rejuvenating set use.

A total of 108 participated in this study. Majority belong to the age of 18-25 years old (42.9%), are female (65.7%), single (76.9%), and unemployed (73.3%). Sunscreen was the most common product used (51.4%). Advertisements in television was the most common factor considered during purchase (28.6%) and most were purchased at drugstores (30.5%). Majority of participants used rejuvenating sets daily (40%) for 1-3 months (32.4%). Most were unaware of the possible adverse effects (56.2%) and did not consult a physician prior to use (84.9%). There was a lack in knowledge on the composition of rejuvenating sets in terms of regulated ingredients (55.2%). A few reported signs and symptoms such as redness (33.3%), dryness (28.6%), and stinging (24.8%) after use.

This study serves as a tool to increase discourse on rejuvenating sets. With the rise in popularity and availability and lack of studies on the side effects, it is imperative that further similar studies be made.

Natural collagen peptides are collagen hydrolysates. Because of their unique physicochemical properties and excellent biological activities, collagen peptides have been a research hotspot of cosmetic raw materials development and skincare efficacy improvement. Combined with the needs of the skincare efficacy and the development trends of cosmetics, the extraction methods and their structural characteristics of natural collagen peptides were summarized in detail. The applications and its research progress in skincare efficacy of collagen peptides, such as moisturizing and anti-wrinkle, trophism and anti-aging, filling and skin regeneration were expressed with emphasis. Finally, the development and practical applications in cosmetics of natural collagen peptides were adequately prospected.

Neonates are easily suffering from local or systematic infections due to their vulnerable skin barrier function, which leads to the increasing risk of death. Therefore, it is important to protect neonatal skin integrity and prevent neonatal skin injury in the neonatal intensive care unit (NICU). Based on Grading of Recommendations Assessment, Development and Evaluation (GRADE) and current evidence, the guidelines for neonatal skin management in the NICU were developed to provide recommendations on routine skin care and prevention and treatment of iatrogenic skin injury of neonates for health care providers.

Hyperammonemia syndrome (HS) is a comparatively rare but often fatal clinical syndrome characterized by progressive respiratory alkalosis and abrupt mental status alteration associated with markedly elevated plasma ammonium levels. Although the exact mechanism of HS remains unclear, infection with urease producing microbes is proposed as the main etiology of HS recently. A patient with HS after repeated autologous skin transplantation was admitted to Tianjin First Center Hospital in March 2018, presented with fever, coma and epilepsy. The infection of Mycoplasma hominis was confirmed in blood sample by high throughput gene detection. The patient was survived after multimodal management including antimicrobial treatment, aggressive ammonia removal by continuous renal replacement therapy in combination with lactulose, and mechanical ventilation. She was successfully discharged from intensive care unit (ICU) with clear consciousness, normal temperature and smooth breath. In view of the experience of the case treatment, a review of literature was conducted to discuss the epidemiology and clinical characteristics, possible etiologies and mechanisms, and outcomes with emphasis on treatment strategies of HS and to promote more clinicians to recognize this rare disease.

PURPOSE: This prospective study was conducted to determine the incidence and related characteristics of respiratory medical device-related pressure ulcers (MDRPU) in children admitted to a pediatric intensive care unit (PICU). METHODS: The participants were 184 children who were admitted to the PICU of P University Hospital from April 2016 to January 2017. Data were collected on the occurrence of respiratory MDRPU and characteristics regarding the application of respiratory medical devices. RESULTS: Respiratory MDRPU occurred in 11.9% of participants (58.3%: stage I ulcers, 37.5%: mucosal ulcers). The devices associated with respiratory MDRPU were endotracheal tubes (54.2%), high-flow nasal cannulas (37.5%), and oximetry probes (8.3%). Respiratory MDRPU associated with an endotracheal tube were significant differences according to the site and strength of fixation, the use of a bite block and adhesive tape, skin dryness, and edema. In high-flow nasal cannulas, significant differences were found according to the site of fixation, immobility after fixation, and skin dryness. CONCLUSION: The occurrence of respiratory MDRPU is significantly affected by the method and strength of fixation, as well as skin dryness and edema. Therefore, appropriate consideration of these factors in nursing care can help prevent respiratory MDRPU.

PURPOSE: The purpose of this study was to investigate the prevalence of diaper dermatitis (DD), knowledge of DD prevention and treatment, and diaper hygiene practices among mothers with diaper-wearing children. METHODS: The participants were 176 mothers who presented to an outpatient clinic at a children's hospital with diaper-wearing children. Data were collected using a structured self-administered questionnaire. RESULTS: The percent of correct answer for knowledge about DD was 59.7%. Almost half of the participants' children had experienced at least 1 episode of DD during the last 6 months. Inappropriate diaper hygiene practices, such as using talcum powder on DD and rubbing with a dry towel after cleansing, were reported. Moreover, only 37% of mothers used the recommended skin barrier to prevent DD. Although many children suffer from DD, levels of educational experience and perceived need for education on this topic were low. Almost 70% of mothers obtained DD-related information through internet sites. CONCLUSION: Educating parents about the etiology of DD and evidence-based diaper hygiene practices is an important aspect of effective DD prevention and treatment. Internet sites or smartphone apps may be effective methods for education on DD prevention and treatment considering parents' preferences for ways to obtain health information.
