To synthesize an amine-modified polyhedral oligomeric silsesquioxane (POSS) nano-structure as a novel co-initiator-crosslinker (co-Ini-Linker) and to determine the effect of the co-Ini-linker on the physical and mechanical behavior of an experimental dental composite.

The amine-methacrylate POSS nano-structures (AMA-POSS) were chemically synthesized by anchoring a tertiary amine functionality on the methacrylate POSS (MA-POSS) branches. Three types of AMA-POSS, having different amine branches in their structures, were synthesized through the Aza Michael reaction. The chemical structure of AMA-POSSs were evaluated by

H-NMR spectroscopy. Afterward, the AMA-POSS was incorporated into a dental resin system composed of Bis-GMA, TEGDMA, and photo-initiator. Three resin systems with different AMA-POSS types were then prepared, and their properties were compared with a resin containing DMAEMA as a conventional co-initiator. The degree of conversion evaluated by FTIR spectroscopy and the shrinkage kinetics of thea reinforcing filler and a cross-linking agent.

The synthesized novel amine-methacrylate POSS nanostructures not only act as an amine co-initiator but also work as a reinforcing filler and a cross-linking agent.

Platelets, fibrinogen and factor XIII (FXIII) are required to form a stable clot in case of haemorrhage. The aims of this study were to evaluate a possible association between FXIII activity at the onset of labour and postpartum haemorrhage (PPH), and to ascertain whether FXIII activity at labour onset differs from after delivery.

FXIII activity in 239 women with PPH (blood loss >1 L) and in 76 women without PPH was compared, as was activity before and after delivery in a third group of 80 women.

FXIII activity at onset of labour was significantly lower in the PPH group compared with the control group (mean ± SD 0.98 ± 0.20 vs 1.05 ± 0.17 kIU/L; P=0.0006). The difference was significantly greater in subgroups having vaginal delivery with no oxytocin stimulation or uterine exploration (absolute difference 0.131; 95% CI 0.055 to 0.206), compared with a subgroup experiencing any complication (0.04; 95% CI -0.023 to 0.104; interaction P-value 0.098). There was a weak but statistically significant inverse correlation between FXIII and estimated blood loss (r=-0.25; P=0.030) in the control group but not the PPH group. There was no significant difference between FXIII activity at onset of labour and after delivery (mean ± SD 1.03 ± 0.17 vs 1.04 ± 0.19 kIU/L; P=0.093).

At the onset of labour women with a subsequent PPH had significantly lower mean FXIII activity than that of women without PPH. This difference was small and within normal limits. FXIII activity did not change during normal delivery. The importance of FXIII during PPH requires study.

The cantilevered resin-bonded fixed dental prosthesis (RBFDP) is a feasible and minimally invasive treatment option to restore a single missing tooth, especially when the missing tooth space is small (<7 mm) and cost-effectiveness is essential. However, its long-term survival needs to be improved by increasing its structural strength and interfacial adhesion.

The purpose of this study was to improve the interfacial bonding and to enhance the structural strength of a 2-unit inlay-retained cantilevered RBFDP with a 2-step numerical shape optimization.

A finite element model of a mandibular first molar with a second premolar pontic was constructed. A load of 200 N simulating the average occlusal force was applied on the mesial fossa of the pontic. In the first step, an in-house user-defined material subroutine was used to generate the cavity preparation. The subroutine iteratively changed the tooth tissues next to the pontic to composite resin according to the local stresses until convergence was achiev6.5 MPa). The peak maximum principal stress was also reduced for the remaining tooth structure by approximately 30% (conventional 372.2 MPa versus optimized 253.1 MPa).

Shape optimization determined that a shovel-shaped retainer with fibers placed near the occlusal surface of the connector area can collectively reduce the interfacial and structural stresses of the 2-unit cantilevered fiber-reinforced RBFDP. This may offer a more conservative treatment option for replacing a single missing tooth.

The analysis of different parameters involved in the esthetic perception of the smile is important for the correct planning of cosmetic dental treatments.

The purpose of this study was to analyze the differences in the main parameters of smile esthetics among celebrities identified as having the best esthetic smiles and a young Southern European population.

The study consisted of a control group of 144 dental students from the University of Seville(69.4% women; 30.6% men) with a mean ±standard deviation age of 23.19 ±0.5 years and photographs of 58 celebrities identified as having the best esthetic smiles (74.1% women; 25.9% men) with a mean ±standard deviation age of 42.09 ±2.25 years. Photographs of the celebrities were obtained from the Internet, and standardized photographs were made of the control group. The variables measured were smile line, smile arc, incisal edges and lower lip relationship, smile width, dental midline deviation and tilting, buccal corridor widths, and angulation discrepancy beiation or tilting of the maxillary midline, showing a greater number of teeth in the smile, displaying incisal edges parallel to the lower lip (particularly in women), and displaying occlusal and commissural planes parallel to the interpupillary line.

The role of minimally invasive surgery for the treatment of early and locally advanced gastric cancer remains controversial. The purpose of this study was to perform a comprehensive evaluation of major surgical approaches for operable distal gastric cancer.

Systematic review and network meta-analyses of randomized controlled trials were performed to compare open distal gastrectomy, laparoscopic-assisted distal gastrectomy, and robotic distal gastrectomy. Risk ratio, weighted mean difference, and 95% credible intervals were used as pooled effect size measures.

Seventeen randomized controlled trials (5,909 patients) were included. Overall, 2,776 (46.8%) underwent open distal gastrectomy, 2,964 (50.1%) laparoscopic-assisted distal gastrectomy, and 141 (3.1%) robotic distal gastrectomy. Among these 3 groups, there were no significant differences in 30-day mortality, anastomotic leak, and overall complications. Compared to open distal gastrectomy, laparoscopic-assisted distal gastrectomy was associated with tal gastrectomy performed by well-trained experienced surgeons, even in the setting of locally advanced gastric cancer, seem associated with improved short-term outcomes with similar overall and disease-free survival compared with open distal gastrectomy.

Most randomized trials on minimally invasive cholecystectomy have been conducted with standard (3/4-port) laparoscopic or open cholecystectomy serving as the control group. However, there exists a dearth of head-to-head trials that directly compare different minimally invasive techniques for cholecystectomy (eg, single-incision laparoscopic cholecystectomy versus needlescopic cholecystectomy). Hence, it remains largely unknown how the different minimally invasive cholecystectomy techniques fare up against one another.

To minimize selection and confounding biases, only randomized controlled trials were considered for inclusion. Perioperative outcomes were compared using frequentist network meta-analyses. The interpretation of the results was driven by treatment effects and surface under the cumulative ranking curve values. A sensitivity analysis was also undertaken focusing on a subgroup of randomized controlled trials, which recruited patients with only uncomplicated cholecystitis.

Ninety-six eligible re may be equipoise for exploring further the utility of novel minimally invasive techniques and potentially incorporating them into the general surgery training curriculum.

The purpose of this study was to consider the use of drainage when performing an abdominoplasty with regards to postoperative complications for two groups of patients.

From January 1st 2017 to December 31th 2019, 215 patients underwent an abdominoplasty in our institution. In this retrospective, comparative, single institution study, patients were divided into two groups "drainage" D (n=162) when suction completed abdominoplasty, "no drainage" ND (n=53) when suction didn't completed abdominoplasty. Early and distant complications were retrieved for each group and compared.

There was no significant difference between the two groups concerning the occurrence of seroma postoperatively (8% of patients in group D and 11.3% of patients in group AD). The drainage group D experienced more seroma's punctures (2,3± 1,0) and the mean of punctured fluid was higher (386,5ml±350,4ml) compared to the no drainage group ND (1,3+- 0,5 number of punctures with a mean punctured fluid of 165,8mL± 224,2mL). The mean hospital stay was shorter for group ND (2,9± 1,8 days) than for group D (4,4+- 1,7 days), P<0,0001.

Performing an abdominoplasty with quilting suture but drainless doesn't seem to increase postoperative complications statistically. 17AAG The authors recommend, under the guise of a quilting suture, not to systematically drain the abdominoplasties and to reserve this technique for patients at risk of complications (high BMI, significant weight loss and co-morbidities).

These illnesses are preventable via vaccination, but uptake is low and decreasing. Little research has focused on understanding the psychosocial reasons behind older adults' hesitancy towards different vaccines. A cross-sectional survey with 372 UK-based adults aged 65-92 years (M = 70.5) assessed awareness and uptake of the influenza, pneumococcal, and shingles vaccines. Participants provided health and socio-demographic data and completed two scales measuring the psychosocial factors associated with vaccination behaviour. Self-reported daily functioning, cognitive difficulties, and social support were also assessed. Participants were additionally given the opportunity to provide free text responses outlining up to three main reasons for their vaccination decisions. We found that considerably more participants had received the influenza vaccine in the last 12 months (83.6%), relative to having ever received the pneumococcal (60.
