Marginal integrity and internal adaptation are key to the long-term success of porcelain laminate veneers. Evidence for their marginal and internal fit is unclear, and the factors affecting such fit have not been identified.

The purpose of this systematic review and meta-analysis was to summarize the scientific literature assessing the effects of various parameters on the marginal and internal fit of porcelain laminate veneers.

An electronic search was conducted to identify all relevant published articles on the fit accuracy of ceramic veneers between January 2000 and June 2021 in the PubMed-MEDLINE, Scopus, Embase, Google Scholar, and Web of Science databases. Information, including the study outcomes, in terms of the mean marginal gap, internal gap, and absolute marginal discrepancies of porcelain laminate veneers, was extracted from the selected studies. The inverse-variance random effects model was used to analyze the pooled results and estimate the overall effect based on the heterogeneity of studirginal fit.
No significant differences were found between the pressed and milled porcelain laminate veneers for marginal gap, but for the internal gap, the differences were significantly in favor of the pressed type. The butt joint veneer preparation design was significantly better than the palatal chamfer design in terms of marginal fit.
According to the International Diabetes Federation, approximately 425 million people worldwide suffer from diabetes mellitus, a figure that will double in the next 20 years. Data on the ratio of treated diabetics in burn intensive care units remain scarce and the effects on the mortality rate are poorly defined.

Our retrospective, single-centre study aimed to evaluate differences in the risk factors due to diabetes mellitus, the clinical outcome and the patient population of diabetic patients after severe burn injuries over a time period of 21 years.

Despite increasing numbers of diabetic patients, the ratio of burn patients suffering from diabetes remained stable during the study period. The risk factors for mortality were higher age (OR 1.03, 95% confidence interval (CI), 1.02-1.04, p<0.0001), female sex (OR 1.56, 95% CI, 1.06-2.29, p=0.025), higher % total body surface area (TBSA) (OR 3.88, 95% CI, 2.81-5.46, p<0.0001), full thickness burns (OR 8.58, 95% CI, 3.84 - 23.60, p<0.0001) and the ppatients without a significant outcome due to the low number of cases in the subgroup analyses.
Traumatic spine fractures can result in chronic pain, disability, and prolonged rehabilitation. The purpose of this study is to determine the long-term effects of traumatic spine fractures on patients' functional outcomes after nonoperative and operative management.

Patients with traumatic spine fractures over a 5-year period were identified and stratified by management strategy (nonoperative and operative) and compared. Functional outcomes were measured using the Boston Activity Measure for PostAcute Care to assess basic mobility and daily activity. Multiple linear regression was used to identify predictors of functional outcome after traumatic spine fractures.

In total, 488 patients were identified 271 nonoperative and 217 operative. Phleomycin D1 in vivo Follow-up was obtained in 168 (34%) patients 95 nonoperative and 73 operative. Mean follow-up was 5.7 years (range 3-8 years). Mean Activity Measure for PostAcute Care scores in patients managed nonoperatively for basic mobility (68 vs 64, P= .09) and daily activity (69 vent. Age, thoracic fractures, lower extremity fractures, discharge location, and time to operative fixation were associated with poor functional outcomes.
Pathologic review of at least 12 lymph nodes is recommended by the American Joint Committee on Cancer following surgical resection of rectal cancer. However, implications of lymph node yield on prognosis are unclear. This study evaluates the impact of lymph node yield on survival among pathologic node-negative patients who received appropriate neoadjuvant chemoradiation.

The National Cancer Database from 2010 to 2016 was queried for clinical stage II and III rectal adenocarcinoma with neoadjuvant chemoradiation, resection of the primary tumor, negative surgical margins, and pN0M0 pathologic stage. Data were analyzed with χ
, student's t test, or Mann-Whitney U test as appropriate. Propensity score matching controlled for clinicodemographic variation. Survival was estimated with Kaplan-Meier curves and Cox hazards analysis.

Inadequate lymph node yield (1-11 nodes on pathology) led to a 29% increased risk of mortality compared to adequate lymph node yield (≥12 nodes on pathology). Among patients with an incomplete pathologic complete response to neoadjuvant therapy, 5-year survival was estimated to be 73% for inadequate lymph node yield and 78% for adequate lymph node yield (P= .002). Among patients with a complete pathologic response, 5-year survival estimated to be 82% for inadequate lymph node yield and 90% for adequate lymph node yield (P= .006). Among patients with inadequate lymph node yield and complete pathologic response, 5-year survival improved with the use of adjuvant chemotherapy (90.4%), compared to those without adjuvant chemotherapy (78.5%, P < .001).

These findings suggest an inadequate lymph node yield can negatively impact survival, despite negative nodal status and a pathologic complete response to neoadjuvant therapy.

To investigate patient preferences and the determinants of participation willingness in orthopaedic diagnostic or invasive surgical randomized controlled trials.

This observational study included one hundred patients visiting an orthopaedic clinic. The patients answered if they were willing to participate in a hypothetical invasive and diagnostic trial among patients with a distal radius fracture.

We found no difference in participation willingness in either the invasive surgical (66/100) or the diagnostic trial (68/100, p=0.76). Willingness to participate was not associated with age, gender, country of origin, level of education, marital status, or distance of home from the hospital with the confidence interval for all odds ratios including the value 1. Patients who expressed willingness to participate do so because they wanted to contribute to science; patients who declined to participate wanted to speak with a doctor and to be better informed.

This study showed a high rate of willingness to participate in orthopaedic surgical invasive trials and in diagnostic trials. Nevertheless, to ensure participation, it is recommended to put emphasis on the contribution to science and to give adequate information about the trial including the opportunity to talk to a doctor.

Although excellent results of cephalomedullary nailing for femoral trochanteric fractures have been reported, excessive sliding has recently been noted as a cause of lag screw cut-out. Excessive sliding is reported as sliding of ≥8mm, which occurs in approximately 40%of cases. This study aimed to evaluate the risk factors for excessive sliding.

Overall, 551 patients who underwent cephalomedullary nail surgery between 2016 and 2021 were recruited. Patients aged ≥65 years who underwent preoperative computed tomography (CT), experienced low-energy trauma, and received follow-up for >4 months were included. Cases were retrospectively reviewed for their postoperative sliding distance and the percentage of excessive sliding (>8 mm). 3D-CT classification, reduction pattern (subtypes A, N, and P) in the lateral view, medullary mismatch, and implant type (short/long Gamma3 nail and INTERTAN) were investigated fortheirimpact on sliding distance andtheincidence of excessive sliding. Complication rates (lag scr024, odds ratio 2.99). There were three lag screw cut-out (1.1%) cases and one non-union (0.4%) case.

Postoperative subtype P is a risk factor for excessive sliding; there was significantly less sliding in the INTERTAN nail group. It is necessary to avoid reduction to subtype P to prevent postoperative excessive sliding.

Recent studies on posterior malleolar fractures mainly focus on the reduction quality and fixation of the posterior fragment since it contributes to ankle stability and articular congruency. However, the association of pre-and postoperative factors considering the whole ankle joint in postoperative functional outcomes remains unclear. Therefore, this study aimed to examine the association between pre-and postoperative variables for postoperative functional outcomes in patients with posterior malleolar fragments (classified as Haraguchi type I or II) and considered the association between reduction and fixation for small posterior malleolar fragments of less than 25% of the intra-articular surface.

This multicenter retrospective cohort study included 110 adult patients who underwent internal fixation for ankle fractures with posterior malleolar fragments. The primary outcome was the American Orthopaedic Foot and Ankle Society (AOFAS) score 12-months postoperatively. As pre-and postoperative variables, the perative complications were associated with AOFAS scores at postoperative 12 months in patients with ankle fractures with posterior malleolar fragments. In patients with small posterior malleolar fragments, reduction and fixation were not associated with AOFAS scores. Therefore, clinical decisions for posterior fragment fixation should be made based on the possible risk of complications related to the surgical procedures in addition to the posterior malleolar fragment size.
Our results suggest that postoperative complications were associated with AOFAS scores at postoperative 12 months in patients with ankle fractures with posterior malleolar fragments. In patients with small posterior malleolar fragments, reduction and fixation were not associated with AOFAS scores. Therefore, clinical decisions for posterior fragment fixation should be made based on the possible risk of complications related to the surgical procedures in addition to the posterior malleolar fragment size.Standardization in allocation of kidneys for transplant simultaneous with livers and the creation of a "safety net" for kidney transplant after liver transplant alone (LTA) was designed to encourage clinicians to list patients for LTA when the likelihood of renal recovery and the necessity of simultaneous liver and kidney (SLK) transplant were unclear. We analyzed the United Network for Organ Sharing database of SLK recipients starting January 1, 2015. Organs from one deceased donor were used in each individual case. Univariate analysis was used to analyze recipient and donor characteristics against patient and graft survival of at least 1 year. Cox regression was employed for multivariable analysis controlling for donor risk index variables. SLK recipients who failed to achieve 1 year of post-transplant survival were more likely to be older, have higher model for end-stage liver disease scores, have diabetes, have received dialysis within one week of transplant, and required intensive care unit admission at transplantation.
