05); we did not obtain statistically significant differences in drainage, blood loss between groups or in the proportion of transfused. When stratifying the results by age, we obtained significant differences in the decrease in haemoglobin (p = 0.021) and haematocrit (p = 0.025) in patients > 65 years. CONCLUSIONS The different routes of administration of TXA in PTC have a similar effect in reducing post-operative bleeding without evidencing an increase in complications. LEVEL OF EVIDENCE I.The acid-base and redox properties of the menaquinones MK-4, MK-7, and MK-9 (vitamin K2) have been studied in DMPC monolayers on mercury electrodes. The monolayers were prepared by adhesion-spreading of menaquinone-spiked DMPC liposomes on a stationary mercury drop electrode. All three menaquinones possess [Formula see text] constants outside the experimentally accessible range, i.e., they are higher than about 12. The standard potentials of MK-4, MK-7, and MK-9 in the DMPC monolayers are very similar, i.e., 0.351, 0.326, and 0.330 V (corresponding to the biochemical standard potentials - 0.063, - 0.088, and - 0.085 V).BACKGROUND The known efficacy of doxorubicin in metastatic breast cancer is countered by its dose-limiting myelosuppression and cardiotoxicity. Pegylated liposomal doxorubicin (PLD) was discovered to overcome these problems. But the data regarding its use in metastatic TNBC (triple-negative breast cancer) is still insufficient. Our study aimed to assess the factors affecting the outcome of the patients with metastatic TNBC who received PLD. RESULTS During a period of 8 years (January 2011-December 2018), we analyzed 39 eligible patients. selleck compound The disease control rate (DCR) was 51.3%. Among all the analyzed factors, two of them significantly affected DCR. The first factor was the chemosensitivity to prior anthracycline. As patients with chemosensitive disease had higher DCR than those with the chemoresistant disease (P = .001). The second factor was the number of prior lines of chemotherapy. As the patients who received two prior lines had a higher DCR than those who received three lines or more (P = .023). Chemosensitivity was the only significant independent factor for DCR (odds ratio = .095, P = .008). For the studied patients, the median progression-free survival (PFS) was 7 months. The anthracycline-chemosensitivity was the only significant independent prognostic factor for PFS (P = .002). The median overall survival (OS) was 12 months. There was a marginally significant effect of anthracycline-chemosensitivity on OS (P = .052). CONCLUSION The anthracycline-chemosensitivity is an independent predictive and prognostic factor for the patients with metastatic TNBC receiving PLD. In developing countries, PLD should be reserved for the patients whose tumors are anthracycline-chemosensitive.OBJECTIVES To perform an anatomical study to analyze the size, weight, and the relationships of the parotid levels proposed by the European Salivary Gland Society (ESGS). MATERIALS AND METHODS Anatomical dissections of the parotid region in 19 human specimens were performed. All dissections were systematically carried out to study the dimensions and weight of each level. We also studied the facial nerve distribution between the different levels and the relative position of the facial nerve main trunk and parotid duct in regard to the Frankfort line plane. RESULTS The facial nerve trunk and the parotid duct were identified in all the 19 specimens, which made it feasible to define the 4 principal levels of the parotid gland body (levels I-IV). Level V was identified in 9 out of 19 dissections (47.5%). For the whole gland, the mean for the height and width dimensions were 66.37 mm and 46.84 mm, respectively, and it weighted 18.13 g. In terms of relative weight regarding the whole gland, level II was always the hntly different morphological disposition. Level IV is the smallest portion of the body gland and level V, when present represents a scarce 5% of the whole body gland weight. The ESGS levels have a clear anatomical basis and the basic references needed to define them are always present.PURPOSE Intramedullary screw fixation is currently considered the gold standard treatment for Jones fractures in the athlete. Besides biological factors (i.e., poor vascularization), mechanical instability induced by the pull of the peroneus brevis tendon (PBT) contributes to deficient Jones fracture healing. This biomechanical study aimed to simulate loads induced by the PBT at the fifth metatarsal and to compare the stability of two intramedullary screw constructs in a Jones fracture fixation model. METHODS Jones fractures were created in 24 human paired specimens, and fixation was achieved with either a solid Jones fracture specific screw (JFXS) (Jones Screw; Arthrex Inc., Naples FL, USA) or a cannulated headless compression screw (HCS) (HCS; DePuySynthes, Solothurn, Switzerland). The PBT was fixed to a mechanical load frame by the use of a cryoclamp. Constructs were loaded in tension for 1000 cycles, followed by an ultimate load test. Construct failure was defined by exceeding 10° of dorsal angulation. RESULTS Preliminary failure occurred more often in HCS constructs (33%) compared to JFXS constructs (0%) (P = 0.044). Mean tensile load to failure reached 123.8 ± 91.4 N in the JFXS group and 91.5 ± 62.2 N in the HCS group (P = 0.337). The mean slope of the load-displacement curve was 24.2 ± 10.4 N/mm for JFXS constructs and 24.7 ± 5.5 N/mm for HCS constructs, respectively (P = 0.887). CONCLUSION This is the first study evaluating the effect of PBT pull on the mechanical stability of Jones fracture fixation. Higher preliminary failure rates of HCS were found under cyclic loading conditions compared to JFXS.BACKGROUND Diagnostic stability of bipolar disorder (BD) in children and adolescents, beyond the first contact has been investigated sparsely. The aim of this study was to investigate the diagnostic stability of BD in children and adolescents using over two decades of nationwide register-based data, and to examine factors associated with change from BD to schizophrenia (ICD-10 F20.x), schizoaffective disorder (ICD-10 F25.x) or other primary psychotic disorders (ICD-10 F23.x-24.x and F28.x-29.x). METHODS Danish register-based data for all incident BD patients diagnosed prior to age 18 years, between January 1st 1995 and December 31st 2014 (N = 519). We graphically illustrated diagnostic change at different follow-up times and studied variables associated with diagnostic change after 3-year follow-up using Poisson regression with robust standard error estimates. RESULTS The diagnosis of incident BD was relatively stable. The diagnosis did not change for 93% of those followed for at least 6 months, and remained unchanged for 86% and 73% of those followed at least 3 years and 10 years, respectively.
