Skin and bone share similarities in terms of biochemical composition.Some authors have hypothesized that their properties could evolve concomitantly with age, allowing the estimation of the parameters of one from those of the other.We performed a systematic review of studies reporting the correlation between skin and bone parameters in women with postmenopausal osteoporosis.Fourteen studies - including 1974 patients - were included in the review.Three of these studies included two groups of participants - osteoporotic and non-osteoporotic - in order to compare skin parameters between them: two studies found a significant difference between the two groups and one did not.Eleven of these studies included one population of interest and compared its skin and bone parameters in a continuous manner: eight studies compared dermal thickness to bone mineral density (seven found a significant correlation [ = 0.19-0.486] and one did not); two studies compared skin elasticity to bone mineral density (both found a significant correlation [ = 0.44-0.57); and one study compared skin collagen to bone mineral density and found a significant correlation ( = 0.587).It can be assumed that the estimation of skin alterations from ageing could help in estimating concomitant bone alterations.

Psoriasis is a multifactorial disorder mediated by IL-17-producing T cells, involving immune cells and skin-constituting cells. Semaphorin 4A (Sema4A), an immune semaphorin, is known to take part in T helper type 1/17 differentiation and activation. However, Sema4A is also crucial for maintaining peripheral tissue homeostasis and its involvement in skin remains unknown.

Infection Management Department, The Fifth Affiliated Hospital of Xinjiang Medical University, Urumqi, Xinjiang, 830011, China.
Background: Surgical site infection (SSI) is a serious complication of spine surgery, leading to prolonged hospital stays, re-operations, and economic losses. The aim of the study was to explore the types and quantities of pathogenic bacteria involved, the incidence of SSI, and to identify the independent risk factors and direct economic impact on patients with postoperative SSI in spine surgery.
Methods: The medical records of spine surgery patients from January 2023 to April 2024 at two hospitals in Xinjiang were retrospectively reviewed.
Application of 3D-printed porous prosthesis for the reconstruction of infectious bone defect with concomitant severe soft tissue lesion: a case series of 13 cases.

Department of Orthopedics, Peking University Third Hospital, No.49, North Garden Rd, HaiDian District, Beijing, 100191, China.
Background: Treating infectious bone defects combined with large soft-tissue lesions poses significant clinical challenges. Herein, we introduced a modified two-stage treatment approach involving the implantation of 3D-printed prostheses and flap repair to treat large segmental infectious tibial bone defects.
Method: We conducted a retrospective study of 13 patients treated at our center between April 2018 and March 2022 for tibial infections owing to posttraumatic infection and chronic osteomyelitis combined with soft tissue defects.
Biological effects, properties and tissue engineering applications of polyhydroxyalkanoates: A review.

Polyhydroxyalkanoates (PHAs) are a group of polymers with a variety of monomers, which are extracted from microorganisms and plants. Due to its good biocompatibility, biodegradability, tunable mechanical property and piezoelectricity, PHAs have been widely used in biomedical fields, such as bone, cartilage, nerve, vascular and skin tissue engineering. This review focuses on the in vivo synthesis, metabolism and biological functions of PHA, and the applications of PHAs in the field of tissue engineering and commercial were also summarized and discussed.

The reconstruction of full-thickness scalp defects with exposed bone can be challenging. A single-stage reconstruction could be the preferred option for patients with multiple comorbidities. We propose using a dermal regeneration template (Matriderm Flex) and full-thickness skin grafts.
