The oral cavity is colonized by several species of microorganisms that can cause dental caries, periodontal diseases, candidiasis, endodontic infections, and, among other diseases related to the dental field. Conventional treatment consists of mechanical removal associated with systemic administration of antimicrobials, which can cause various side effects and microbial resistance. In this context, alternative therapies have been developed, including Antimicrobial Photodynamic Therapy (aPDT). For the improvement of therapy, the implementation of nanotechnology is very important to optimize the delivery system of the dyes or photosensitizers on biological targets. Besides, this combination provides a non-invasive treatment, better solubility and bioavailability, delivery to the target site, controlled release and protection against external and physical-chemical factors, low side effects, and, unlikely resistant species. Although, there are numerous researches on aPDT and nanotechnology, few review articles based on the combination of these three aspects nanosystems, aPDT and oral infections are available. For this reason, this article aims to discuss the advances and advantages of this combination. Therefore, this article was divided into different types of nanosystems (organic and inorganic nanoparticles) associated with aPDT bringing a description of it is definitions, properties, and, applications in oral infections.This study focuses on developing a predictive dynamic model for spring-driven autoinjectors. The values of unknown physical parameters, such as the heat convection coefficient and the friction force between the plunger and the syringe barrel, are obtained by fitting the experimentally measured displacements of the plunger and the syringe barrel. The predicted kinematics of the components, such as the displacement and velocity of the syringe barrel, agree well with the experiments with a l2-norm error smaller than 10%. The predictions of the needle displacement at the start of drug delivery agree with the experimental measurements with a l2-norm error of 20%. The maximum air gap pressure and temperature decrease with the initial air gap height but increase with the elasticity and viscosity of the plunger and the mechanical stop. The proposed experimentally validated dynamic model can be effectively used for device design optimization as it is not computationally demanding.
Whether sex is associated with outcomes of out-of-hospital cardiac arrest (OHCA) is unclear.

This study examined sex differences in survival in patients with OHCA without ST-segment elevation myocardial infarction (STEMI).

Using data from the randomized controlled Coronary Angiography after Cardiac Arrest (COACT) trial, the primary point of interest was sex differences in OHCA-related one-year survival. Secondary points of interest included the benefit of immediate coronary angiography compared to delayed angiography until after neurologic recovery, angiographic and clinical outcomes.

In total, 522 patients (79.1% men) were included. Overall one-year survival was 59.6% in women and 63.4% in men (HR 1.18; 95% CI 0.76-1.81;p = 0.47). No cardiovascular risk factors were found that modified survival. Women less often had significant coronary artery disease (CAD) (37.0% vs. 71.3%;p < 0.001), but when present, they had a worse prognosis than women without CAD (HR 3.06; 95% CI 1.31-7.19;p = 0.01). This was not the case for men (HR 1.05; 95% CI 0.67-1.65;p = 0.83). In both sexes, immediate coronary angiography did not improve one-year survival compared to delayed angiography (women, odds ratio (OR) 0.87; 95% CI 0.58-1.30;p = 0.49; vs. men, OR 0.97; 95% CI 0.45-2.09;p = 0.93).

In OHCA patients without STEMI, we found no sex differences in overall one-year survival. Women less often had significant CAD, but when CAD was present they had worse survival than women without CAD. This was not the case for men. Both sexes did not benefit from a strategy of immediate coronary angiography as compared to delayed strategy with respect to one-year survival.

Out-of-hospital cardiac arrest (OHCA) and chronic liver disease (CLD) are global health issues. The purpose of this study is to evaluate the association between chronic liver disease and clinical outcomes in OHCA.

A retrospective observation study, using a nationwide population-based OHCA registry, was conducted. Adult patients with cardiac OHCAs who were treated by emergency medical service (EMS) providers between January 2013 and December 2015 were screened. The main exposure was the status of chronic liver disease that had been diagnosed before OHCA, categorized into three groups no CLD, CLD without cirrhosis, and CLD with cirrhosis. Multivariable logistic regression analysis for survival and neurologic recovery were conducted to calculate the adjusted odds ratio (AOR) and confidence intervals (CIs). Interaction analysis for age, gender were performed and sensitivity analysis by imputation for main exposure missing was also.

A total of 8844 eligible OHCA patients were enrolled. There were 361 (4.1%) ical outcomes and CLD had no negative association unless they progressed to cirrhotic status.
Good quality basic life support (BLS) is associated with improved outcome from cardiac arrest. Chest compression fraction (CCF) is a BLS quality indicator, which may be influenced by the type of airway used. We aimed to assess CCF according to the airway strategy in the PARAMEDIC2 study no advanced airway, supraglottic airway (SGA), tracheal intubation, or a combination of the two. Our hypothesis was that tracheal intubation was associated with a decrease in the CCF compared with alternative airway management strategies.

PARAMEDIC2 was a multicentre double-blinded placebo-controlled trial of adrenaline vs placebo in out-of-hospital cardiac arrest. Data showing compression rate and ratio from patients recruited by London Ambulance Service (LAS) as part of this study was collated and analysed according to the advanced airway used during the resuscitation attempt.

CPR process data were available from 286/ 2058 (13.9%) of the total patients recruited by LAS. The mean compression rate for the first 5 min of data recording was the same in all groups (P = 0.272) and ranged from 104.2 (95% CI of mean 100.5, 107.8) min
to 108.0 (95% CI of mean 105.1, 108.3) min
. The mean compression fraction was also similar across all groups (P = 0.159) and ranged between 74.7% and 78.4%. There was no difference in the compression rates and fractions across the airway management groups, regardless of the duration of CPR.

There was no significant difference in the compression fraction associated with the airway management strategy.
There was no significant difference in the compression fraction associated with the airway management strategy.
With bystander AED usage being critical for prehospital cardiac arrest patient outcomes, it is important to analyze if the gender and location disparities found in bystander CPR rates also exist for bystander AED usage.

Using the National Emergency Medical Services Information System (NEMSIS) database, 1,144,969 bystander AED cases were analyzed on the basis of gender and location. Chi-squared testing checked for statistical significance and effect size was measured using relative risk (RR).

Using female patients as a baseline, the RR for bystander AED usage for male patients was 1.34 (95% CI [1.3310, 1.3557], p < 0.001) indicating male patients are 34% more likely to receive bystander AED usage compared to female patients. Analyzing bystander AED usage per urbanity region using urban patients as a baseline, resulted in a RR of 0.87 for suburban patients (95% CI [0.8572, 0.8833], p < 0.001), 0.39 for rural patients (95% CI [0.3849, 0.3971], p < 0.001), and 0.36 for frontier patients (95% CI [0.and frontier AED availability and training are necessary to increase bystander AED usage rates in those regions.
Recent studies suggest that volatile anaesthetics are safe, efficient, and reliable alternatives to the use of intravenous anaesthetics for out-of-hospital cardiac arrest (OHCA) patients admitted to the intensive care unit (ICU). We hypothesised that volatile anaesthetics may reduce the incidence of delirium rather than intravenous sedatives. This retrospective study aimed to investigate whether sevoflurane combined with higher targeted temperature management could decrease the incidence of delirium when compared with intravenous anaesthetics with lower targeted temperature management.

Using a propensity score-matched analysis, we retrospectively compared a target temperature management (32-34 °C) method along with intravenous sedation (TTM-33/IV) and a modified target temperature management (34-36 °C) method along with sevoflurane sedation (mTTM-36/sevo). We used the confusion assessment method for the ICU to measure the incidence of delirium. We calculated the time-dependent risk on delirium using the mtravenous sedation combined with the classical cooling protocol.This experimental studies investigated the protective efficiencies and the potential immune mechanisms of vibrio monovalent and polyvalent autogenous formalin-inactivated whole-cell bacterins (FKC) in Gilthead sea bream (Sparus aurata) cultured in Egypt. Two months post-vaccination, the relative percentage survival (RPS) was estimated after challenge with the vaccine's homologues pathogenic strains. The survival values were 100% and 83.3% in groups immunized with monovalent V. alginolyticus or V. parahaemolyticus FKC bacterins, respectively. On the other hand, survival values were 91.75% and 75% in fish groups subjected to polyvalent (V. parahaemolyticus O11 K40 & V. alginolyticus) and (V. parahaemolyticus O3 K6 & V. alginolyticus) FKC bacterins, respectively. Overall, the tested vaccine preparations were significantly increased (P less then 0.05) the agglutination antibody titer, phagocytic activity, respiratory burst activity, when compared to the non-immunized control group. The current results conclude that, autogenous Vibrio vaccines provoked a promising protection against vibriosis in Gilthead sea bream cultured in Egypt, it was superior in monovalent FKC V. alginolyticus vaccine and polyvalent FKC of V. parahaemolyticus O11 K40 with V. alginolyticus vaccine that could be useful means of prevention and control of vibriosis.
This study aims to investigate the long-term demineralization-inhibition capability of a rechargeable adhesive with nanoparticles of amorphous calcium phosphate (NACP) on dentin in a biofilm-challenged environment.

The NACP adhesive was immersed in a pH 4 solution to exhaust calcium (Ca) and phosphate (P) ions and then recharged with Ca and P ions. Dentin samples were demineralized underStreptococcus mutans biofilms for 24 h and randomly divided into two groups (1) dentin control, (2) dentin with recharged NACP adhesives. Each day, all the samples were immersed in brain heart infusion broth with 1% sucrose (BHIS) for 4 h, and then in artificial saliva (AS) for 20 h. This cycle was repeated for 10 days. The pH of BHIS, the Ca and P ions content of the BHIS and AS were measured daily. After 10 days, the lactic acid production and colony-forming units of the biofilms were tested. TCPOBOP in vivo The changes of remineralization/demineralization were also analyzed.

Dentin in the control group showed further demineralization.
