AbstractA novel treatment approach to address the nasolabial fold is the insertion facial suspension threads. However, there is a paucity of data available to guide insertion techniques and material selection. Three female and two male cephalic specimens of Caucasian ethnicity (73.6 ± 6.5 years; 21.41 ± 2.2 kg/m2) were included into this experimental split-face study. One facial side was treated with polycaprolactone (PCL) thread: 180 mm, bidirectional, 18G 100 mm cannula, 20 degrees trajectory, preauricular approach whereas the contralateral side was treated with polydioxanone (PDO) thread: 100 mm, bidirectional, 19G, 60 mm cannula, 50 degrees trajectory, infraorbital approach. Three-dimensional imaging outcome measures included vertical and horizontal skin displacement and volume changes at the nasolabial sulcus, at the labiomandibular sulcus, and along the jawline. Comparing PCL 180 mm 20 degrees to PDO 100 mm 50 degrees: vertical lifting effect 1.42 ± 2.63 mm versus 1.24 ± 1.88 mm (p = 0.906); horizontal lifting effect 3.42 ± 1.44 mm versus –2.02 ± 1.84 mm (p = 0.001); nasolabial volume change –0.80 ± 0.65 mL versus –0.52 ± 0.17 mL (p = 0.367); labiomandibular volume change –0.45 ± 0.42 mL versus –0.16 ± 0.16 mL (p = 0.191); jawline volume change 0.02 ± 0.43 mL versus –0.01 ± 0.21 mL (p = 0.892). The study provides objective evidence for the short-term effectiveness of facial suspension threads in treating the nasolabial folds. The results point toward a better aesthetic outcome when utilizing long facial suspension threads that can effect full-face changes as compared with short facial suspension threads.

Cephalopelvic disproportion (CPD)-related obstructed labour requires delivery via Caesarean section (C/S); however, in low-resource settings around the world, facilities with C/S capabilities are often far away. This paper reports three low-cost tools to assess the risk of CPD, well before labour, to provide adequate time for referral and planning for delivery. We performed tape measurement- and three-dimensional (3D) camera-based anthropometry, using two 3D cameras (Kinect and Structure) on primigravida, gestational age ≥ 36 weeks, from Addis Ababa, Ethiopia. Novel risk scores were developed and tested to identify models with the highest predicted area under the receiver-operator characteristic curve (AUC), detection rate (true positive rate at a 5% false-positive rate, FPR) and triage rate (true negative rate at a 0% false-negative rate). For tape measure, Kinect and Structure, the detection rates were 53%, 61% and 64% (at 5% FPR), the triage rates were 30%, 56% and 63%, and the AUCs were 0.871, 0.908 and 0.918, respectively. Detection rates were 77%, 80% and 84% at the maximum J -statistic, which corresponded to FPRs of 10%, 15% and 11%, respectively, for tape measure, Kinect and Structure. Thus, tape measurement anthropometry was a very good predictor and Kinect and Structure anthropometry were excellent predictors of CPD risk.

We review the phenomenological approach, on the macroscopic or Darcy scale, to flow and volume change in clays and other swelling media. The formulation represents the generalization to media subject to volume change of the well-established phenomenological approach to flow in non-swelling media primarily established in the context of soil physics. The one-dimensional generalization to swelling media is straightforward, and may be usefully applied to practical one-dimensional systems, including three-component systems with solid particles, water, and air. On the other hand, the further generalizations to two- and three-dimensional systems have not yet been developed fully convincingly. Difficult questions include the mode of stress transmission and the tensorial stress-strain relations in multidimensional and multi-component systems. One means of gaining insight into these questions for media of high colloid content (such as clays) is through relevant solutions of the Poisson-Boltzmann equation governing electrical double-layer interactions in dense arrays of colloidal particles. These solutions give pertinent information on both the macroscopic and the microscopic scales. We present a progress report on work along these lines.

Aim. To study the diagnostic and prognostic potential of the complex use of ultrasound and 3D laparoscopy in women with pelvic varicose veins (PVV). Outcomes and methods. The study included 100 women who were divided into two groups: the main group (39 patients with various severity PVV) and the control group (61 women with no venous system disorders). All patients had a complete clinical examination with the selection of pairs that had the most significant factors for the disease prognosis: average age over 35 years, history of varicose veins, pain in the lower abdomen, dysmenorrhea and dyspareunia. Examination of the small pelvis venous system included duplex angioscanning and retrograde endoscopic functional test controlled by the three-dimensional image. Multivariate analysis (logistic regression) was used to identify normative phlebological parameters. Results. Predictors of early PVV are the following rations: Vmax in the cava-ovarian segment / Vmax in the right ovary portal ≥ 8.3 and Vmax in the reno-ovarian segment /Vmax in the left ovarian portal ≥ 8. The severity of PVV is determined by a progression of alterations in hemodynamic parameters in the main ovarian veins and a spreading venous congestion in the small pelvis plexuses. Conclusions. Criteria of small pelvis phlebohemodynamics make it possible to predict a development of PVV and a severity of the pathological process. Ovarian varicose veins are characteristic of early PVV and venous plethora of all pelvis venous plexuses is characteristic of late PVV.
