SUMMARY Background: In the preparation of inlay cavities, a choice must be made between conventional standard and minimally invasive preparation designs; in the long run, this choice can affect the integrity of the bonded interface. Purpose: To evaluate the effect of minimally invasive cavity preparation designs on the extent and contributing mechanisms of damage to ceramic inlay bonded interfaces. Methods and Materials: Tooth blocks with 90°, 120° and 75° marginal angles were prepared, representing tooth cavities with conventional standard and minimally invasive preparations with large divergence and convergence angles and bonded to monolithic ceramic (IPS e.max CAD). Vickers indentations were placed at various distances from the bonded interface. The indentation morphology and crack length were observed. Reciprocating wear tests were performed on the bonded interface with a 20-newton (N) vertical load. The wear depth and wear-scar morphology were characterized after increments of cyclic sliding contact. Results: The 120° group exhibited longer indentation cracks in the ceramic, whereas the 75° group showed larger indentations in the enamel when compared to the 90° group (p<0.001). Consistent with the weaker edge crack resistance, the 120° group experienced the greatest wear (p=0.008), and the wear depth in the enamel of the 75° group exceeded that of the 90° group (p<0.001) in the early stage (5×102 cycles). However, no significant difference in the wear depth (p>0.147) and morphology were found at the later wear stage among the three groups. Conclusion: Within the limitations of this study, minimally invasive preparations with 120° and 75° marginal angles can result in early sever damage at the ceramic inlay bonded interface but show comparable wear behaviors to the conventional 90° group at the later stage.

Abstract Background Postoperative radiotherapy (RT) or chemoradiotherapy (CRT) improves outcomes of cervical cancer patients with risk factors. Minimally invasive surgery (MIS) has an inferior survival than open radical hysterectomy (ORH), however, the impact of MIS on postoperative RT remains uncertain. The study compared the impacts of MIS versus ORH on delivering of adjuvant RT or CRT for intermediate- or high-risk early-stage cervical cancer. Methods Data on stage IB1-IIA2 patients who underwent radical hysterectomy and postoperative RT/CRT in our institution, from 2014 to 2017, were retrospectively collected. Patients with high or intermediate-risk factors who met the Sedlis criteria received postoperative pelvic external beam radiotherapy (50Gy/25f) with platinum-based chemotherapy (0–6 cycles) according to guidelines. Disease-free survival (DFS) and overall survival (OS) were compared in the two surgical groups. Results One hundred and twenty-nine patients eligible for the study (68 in ORH; 61 in MIS groups) had similar clinicopathologic features except for the stage (highest in MIS was IB1; IIA1 in ORH) and presence of lymph vascular space invasion (higher in MIS group). The median time interval from surgery to chemotherapy and to RT was shorter in the MIS group. Three-year DFS and OS were similar in both groups. Further sub-analysis indicated that the DFS and OS in intermediate/high-risk groups had no significant difference. Cox-multivariate analyses found that tumor size > 4 cm and time interval from surgery to RT beyond seven weeks were adverse independent prognostic factors for DFS. Conclusions In early-stage (IB1-IIA2) cervical cancer patients with intermediate or high-risk factors who received postoperative RT or CRT, no matter they received ORH or MIS as their primary treatment, the DFS and OS had no significant difference, despite TI from surgery to postoperative adjuvant therapy being shorter in the MIS group than ORH.

Objective: The aim of the study was to perform a systematic assessment of disease-free survival (DFS), overall survival, and morbidity rates after open radical hysterectomy (ORH) and minimally invasive surgery (MIS) for early-stage cervical cancer and discuss with experts the consequences of the LACC trial (published by Ramirez et al. in 2018) on clinical routine. Methods: A total of 5428 records were retrieved. After exclusion based on text screening, four records were identified for inclusion. Five experts from three independent large-volume medical centers in Europe were interviewed for their interpretation of the LACC trial. Results: The LACC trial showed a significantly higher risk of disease progression with MIS compared to ORH (HR 3.74, 95% CI 1.63 to 8.58). This was not seen in one epidemiological study and was contradicted by one prospective cohort study reported by Greggi et al. A systematic review by Zhang et al. mentioned a similar DFS for robot-assisted radical hysterectomy (RRH) and LRH. Recurrence rates were significantly higher with MIS compared to ORH in the LACC trial (HR 4.26, 95% CI 1.44 to 12.60). In contrast, four studies presented by Greggi reported no significant difference in recurrence rates between LRH/RRH and ORH, which concurred with the systematic reviews of Zhang and Zhao. The experts mentioned various limitations of the LACC trial and stated that clinicians were obliged to provide patients with detailed information and ensure a shared decision-making process. Conclusions: The surgical treatment of early-stage cervical cancer remains a debated issue. More randomized controlled trials (RCT) will be needed to establish the most suitable treatment for this condition.

PURPOSE We evaluated disease and treatment characteristics of patients with relapse after risk-adapted first-line treatment of early-stage, favorable, classic Hodgkin lymphoma (ES-HL). We compared second-line therapy with high-dose chemotherapy and autologous stem cell transplantation (ASCT) or conventional chemotherapy (CTx). METHODS We analyzed patients with relapse after ES-HL treated within the German Hodgkin Study Group HD10+HD13 trials. We compared, by Cox proportional hazards regression, progression-free survival (PFS) after relapse (second PFS) treated with either ASCT or CTx and performed sensitivity analyses with overall survival (OS) from relapse and Kaplan-Meier statistics. RESULTS A total of 174 patients’ disease relapsed after treatment in the HD10 (n = 53) and HD13 (n = 121) trials. Relapse mostly occurred > 12 months after first diagnosis, predominantly with stage I-II disease. Of 172 patients with known second-line therapy, 85 received CTx (49%); 70, ASCT (41%); 11, radiotherapy only (6%); and 4, palliative single agent therapies (2%). CTx was predominantly bleomycin, etoposide, doxorubicin cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP [68%]), followed by the combination regimen of doxorubicin, bleomycin, vinblastine, and dacarbazine (19%), or other regimens (13%). Patients aged > 60 years at relapse had shorter second PFS (hazard ratio [HR], 3.0; P = .0029) and were mostly treated with CTx (n = 33 of 49; 67%) and rarely with ASCT (n = 8; 16%). After adjustment for age and a disadvantage of ASCT after the more historic HD10 trial, we did not observe a significant difference in the efficacy of CTx versus ASCT for second PFS (HR, 0.7; 95% CI, 0.3 to 1.6; P = .39). In patients in the HD13 trial who were aged ≤ 60 years, the 2-year, second PFS rate was 94.0% with CTx (95% CI, 85.7% to 100%) versus 83.3% with ASCT (95% CI, 71.8% to 94.8%). Additional sensitivity analyses including OS confirmed these observations. CONCLUSION After contemporary treatment of ES-HL, relapse mostly occurred > 12 months after first diagnosis. Polychemotherapy regimens such as BEACOPP are frequently administered and may constitute a reasonable treatment option for selected patients with relapse after ES-HL.

The purpose of the research is to determine the etiopathogenesis of reproductive dysfunction in highly productive cows. For this, one group of cows was formed on the principle of paranalogs in the amount of 37 animals inseminated in the first sexual hunt after calving, followed by taking blood samples from them using the Monovet system, considering the duration of pregnancy. During the start-up period, blood was taken 1–4 days before calving and on the first day after calving. A total of 253 blood samples were examined. Subsequently, depending on the effectiveness of insemination, animals were divided into two groups. The first group included inseminated cows after the first insemination (20 animals), the second group included 17 unfertilized cows after the first insemination. Subsequently, blood was taken from animals considering the course of childbirth and the postpartum period. Blood counts were studied according to generally accepted methods using certified equipment. The study found that at an early stage of pregnancy, cows have a significant difference in lipid metabolism and in their peroxidation, in the state of antioxidant systems compared to unstable animals. In the process of pregnancy development in cows, there is a decrease in the level of total lipids and their class, and the accumulation of products of transoxidation of lipids is reduced. In animals with retention of the placenta, a low lipid metabolism and a higher level of peroxidation were established already in the dry period. After calving, this difference increases. The obtained data can be used to develop an algorithm for the prevention of postpartum complications in cows by using substances with antioxidant properties.

Abstract Background The quest for better patient outcomes is driving to the development of minimally invasive spine surgical techniques. There are several evidences on the use of microsurgical decompression surgery for degenerative lumbar spine stenosis; however, few of these studies compared their outcomes with the traditional laminectomy technique. Objectives The aim of our study was to compare outcomes following microsurgical decompression via unilateral laminotomy for bilateral decompression (ULBD) of the spinal canal to the standard open laminectomy for cases with lumbar spinal stenosis. Subjects and methods Cases were divided in two groups. Group (A) cases were operated by conventional full laminectomy; Group (B) cases were operated by (ULBD) technique. Results from both groups were compared regarding duration of surgery, blood loss, perioperative complication, and postoperative outcome and patient satisfaction. Results There was no statistically significant difference between both groups regarding the improvement of visual pain analogue, while improvement of neurogenic claudication outcome score was significant in group (B) than group (A). Seventy-three percent of group (A) cases and 80% of group (B) stated that surgery met their expectations and were satisfied from the outcome. Conclusion Comparing ULBD with traditional laminectomy showed the efficacy of the minimally invasive technique in obtaining good surgical outcome and patient satisfaction. There was no statistically significant difference between both groups regarding the occurrence of complications The ULBD technique was found to respect the posterior spinal integrity and musculature, accompanied with less blood loss, shorter hospital stays, and shorter recovery periods than the open laminectomy technique.

As age advances, breast cancer (BC) tends to change its biological characteristics. This study aimed to explore the natural progression of such changes. The study included 2383 women with clinically T0-2N0-1M0 BC, managed by primary surgery and optimal adjuvant therapy in a dedicated BC facility. Tissue micro-arrays were constructed from their surgical specimens and indirect immunohistochemistry was used for analysis of a large panel (n = 16) of relevant biomarkers. There were significant changes in the pattern of expression of biomarkers related to luminal (oestrogen receptor (ER), progesterone receptors (PgR), human epidermal growth factor receptor (HER-2), E-cadherin, MUC1, bcl2 CK7/8, CK18 and bcl2) and basal (CK5/6, CK14, p53 and Ki67) phenotypes, lymph node stage, histological grade and pathological size when decade-wise comparison was made (p < 0.05). The ages of 40 years and 70 years appeared to be the milestones marking a change of the pattern. There were significantly higher metastasis free and breast cancer specific survival rates among older women with ER positive tumours while there was no significant difference in the ER negative group according to age. Biological characteristics of BC show a pattern of change with advancing age, where 40 years and 70 years appear as important milestones. The pattern suggests <40 years as the phase with aggressive phenotypes, >70 years as the less aggressive phase and 40–70 years being the transitional phase.

AbstractObjectiveCompare the efficacy of two interventions addressing emotional and existential well-being in early life-limiting illness.MethodPrimary trial analysis (n = 135) included patients with advanced cancer, congestive heart failure, or end-stage renal disease; Arm 1 received the Outlook intervention, addressing issues of life completion and preparation, and Arm 2 received relaxation meditation (RM). Primary outcomes at five weeks (primary endpoint) and seven weeks (secondary): completion and preparation (QUAL-E); secondary outcomes: anxiety (POMS) quality of life (FACT-G) and spiritual well-being (FACIT-Sp) subscales of faith, meaning, and peace.ResultsAverage age was 62; 56% were post-high school-educated, 54% were married, 52% white, 44% female, and 70% had a cancer diagnosis. At baseline, participants demonstrated low levels of anxiety (<5 on POMS subscale) and depression (<10 on CESD) relative to population norms. Results of the primary analysis revealed no significant differences in mean Preparation by treatment arm at five weeks (14.4 Outlook vs. 14.8 RM; between-group difference −0.4 [95% CI, −1.6, 0.8], p = 0.49) or seven weeks (15.2 vs.15.4; between-group difference −0.2 [95% CI, −1.5, 1.0], p = 0.73). There were also no significant differences in mean Life Completion by treatment arm between five weeks (26.6 Outlook vs. 26.3 RM; between-group difference 0.2 [95% CI, −1.2, 1.7], p = 0.76) or seven weeks (26.5 vs. 27.5; between-group difference −1.0 [95% CI, −2.7, 0.7], p = 0.23). Compared to RM, Outlook participants did not have significant differences over time in the secondary outcomes of overall quality of life, anxiety, depression, FACT-G subscales, and FACIT-Sp subscales.DiscussionIn early-stage life-limiting illness, Outlook did not demonstrate a significant difference in primary or secondary outcomes relative to RM. Results underscore the importance of pre-screening for distress. Qualitatively, Outlook participants were able to express suppressed emotions, place illness context, reflect on adaptations, and strengthen identity. Screening for distress and identifying specified measures of distress, beyond anxiety and depression, is essential in our ability to adequately assess the multi-dimensional mechanisms that decrease existential suffering.

Abstract Purpose The purpose of this study is to evaluate inter- and intra-fraction organ motion as well as to quantify clinical target volume (CTV) to planning target volume (PTV) margins to be adopted in the stereotactic treatment of early stage glottic cancer. Methods and materials Stereotactic body radiotherapy (SBRT) to 36 Gy in 3 fractions was administered to 23 patients with early glottic cancer T1N0M0. Patients were irradiated with a volumetric intensity modulated arc technique delivered with 6 MV FFF energy. Each patient underwent a pre-treatment cone beam computed tomography (CBCT) to correct the setup based on the thyroid cartilage position. Imaging was repeated if displacement exceeded 2 mm in any direction. CBCT imaging was also performed after each treatment arc as well as at the end of the delivery. Swallowing was allowed only during the beam-off time between arcs. CBCT images were reviewed to evaluate inter- and intra-fraction organ motion. The relationships between selected treatment characteristics, both beam-on and delivery times as well as organ motion were investigated. Results For the population systematic (Ʃ) and random (σ) inter-fraction errors were 0.9, 1.3 and 0.6 mm and 1.1, 1.3 and 0.7 mm in the left-right (X), cranio-caudal (Y) and antero-posterior (Z) directions, respectively. From the analysis of CBCT images acquired after treatment, systematic (Ʃ) and random (σ) intra-fraction errors resulted 0.7, 1.6 and 0.7 mm and 1.0, 1.5 and 0.6 mm in the X, Y and Z directions, respectively. Margins calculated from the intra-fraction errors were 2.4, 5.1 and 2.2 mm in the X, Y and Z directions respectively. A statistically significant difference was found for the displacement in the Z direction between patients irradiated with > 2 arcs versus ≤ 2 arcs, (MW test, p = 0.038). When analyzing mean data from CBCT images for the whole treatment, a significant correlation was found between the time of delivery and the three dimensional displacement vector (r = 0.489, p = 0.055), the displacement in the Y direction (r = 0.553, p = 0.026) and the subsequent margins to be adopted (r = 0.626, p = 0.009). Finally, displacements and the subsequent margins to be adopted in Y direction were significantly greater for treatments with more than 2 arcs (MW test p = 0.037 and p = 0.019, respectively). Conclusions In the setting of controlled swallowing during treatment delivery, intra-fraction motion still needs to be taken into account when planning with estimated CTV to PTV margins of 3, 5 and 3 mm in the X, Y and Z directions, respectively. Selected treatments may require additional margins.

Abstract Background The purpose of this study was to investigate the clinical effect of minimally invasive surgery for inguinal cryptorchidism. Methods The patients were divided into the minimally invasive surgery group (n = 100) and the traditional surgery group (n = 58). In the minimally invasive surgery group, patients with low inguinal cryptorchidism (n = 54) underwent surgery with a transscrotal incision, and patients with high inguinal cryptorchidism (n = 46) underwent laparoscopic surgery. Results There was no difference in the hospital stay duration or cost between the minimally invasive surgery group and the traditional surgery group (P > 0.05). As for the operative time, minimally invasive surgery of low inguinal cryptorchidism was shorter than traditional surgery (P = 0.033), while minimally invasive surgery of high inguinal cryptorchidism was comparable to traditional surgery (P = 0.658). Additionally, there were no cases of testicular atrophy, testicular retraction, inguinal hernia or hydrocele in either group. There was no significant difference in the incidence of poor wound healing between the two groups (P > 0.05). Although there was no significant difference in the incidence of scrotal hematoma between the two groups (P > 0.05), the incidence in the minimally invasive surgery group was higher than that in the traditional surgery group. Conclusions Minimally invasive surgery including a transscrotal incision for low inguinal cryptorchidism and laparoscopic surgery for high inguinal cryptorchidism is as safe and effective as traditional surgery, and could also provide a good cosmetic effect for children.

<b><i>Introduction:</i></b> Injuries to surrounding structures during radical prostatectomy (RP) are rare but serious complications. However, it remains unknown if injuries to intestines, rectum, or vascular structures occur at different rates depending on the surgical approach. <b><i>Methods:</i></b> We compared the frequency of these outcomes in open RP (ORP) and minimally invasive RP (MIS-RP) using the national American College of Surgeons National Surgical Quality Improvement Program database (2012–2017). Along with important metrics of clinical and surgical outcomes, patients were identified as undergoing surgical repair of small or large bowel, vascular structures, or hernias based on Current Procedural Terminology codes. <b><i>Results:</i></b> In our propensity matched analysis, a total of 13,044 patients were captured. Bowel injury occurred more frequently in ORP than in MIS-RP (0.89 vs. 0.26%, <i>p</i> &#x3c; 0.01). By intestinal segment, rectal and large bowel injuries were more common in ORP than MIS-RP (0.41 vs. 0.11% and 0.31 vs. 0.05%, both <i>p</i> &#x3c; 0.01). However, there was no statistically significant difference between the groups for small bowel injury (0.17 vs. 0.11%, <i>p</i> = 0.39). Vascular injury was more common in MIS-RP (0.18 vs. 0.08%, <i>p</i> = 0.08). Hernias requiring repair were only identified in the MIS-RP group (0.12%). <b><i>Conclusion:</i></b> When considering surgical approach, rectal and large bowel injuries were more common in ORP, while vascular injuries and hernia repair were more common in MIS-RP. Our findings can be used in counseling patients and identifying risk factors and strategies to reduce these complications.
