Timely intervention in growing individuals, such as brace treatment, relies on early detection of adolescent idiopathic scoliosis (AIS). To this end, several screening methods have been implemented. However, these methods have limitations in predicting the Cobb angle.

This study aimed to evaluate the performance of a three-dimensional depth sensor imaging system with a deep learning algorithm, in predicting the Cobb angle in AIS.

Retrospective analysis of prospectively collected, consecutive, nonrandomized series of patients at five scoliosis centers in Japan.

One hundred and-sixty human subjects suspected to have AIS were included.

Patient demographics, radiographic measurements, and predicted Cobb angle derived from the deep learning algorithm were the outcome measures for this study.

One hundred and sixty data files were shuffled into five datasets with 32 data files at random (dataset 1, 2, 3, 4, and 5) and five-fold cross validation was performed. The relationships between the actual and preddimensional depth sensor imaging system with its newly innovated convolutional neural network for regression is objective and has significant ability to predict the Cobb angle in children and adolescents. This system is expected to be used for screening scoliosis in clinics or physical examination at schools.

Previous studies have shown that oblique lateral interbody fusion (OLIF) can improve neurological symptoms via "indirect decompression." However, data are lacking in terms of its benefits when compared with conventional transforaminal lumbar interbody fusion (TLIF) and/or posterior lumbar interbody fusion (PLIF) approach, especially in patients with severe central canal stenosis.

To investigate the clinical outcome of OLIF without posterior decompression versus conventional TLIF and/or PLIF in severe lumbar stenosis diagnosed on preoperative magnetic resonance imaging.

Retrospective comparative study.

Fifty-one patients who underwent OLIF and 41 patients who underwent conventional TLIF and/or PLIF.

Clinical outcome score by Japanese Orthopedic Association (JOA) score and radiographic outcomes (disc height and fusion rate on computed tomography scan).

We retrospectively reviewed 51 patients who underwent OLIF with supplemental percutaneous pedicle screws (55 levels; OLIF group) and 41 patients who In 1970, Jean-Yves de la Caffinière developed the first trapeziometacarpal (TMC) joint prosthesis, a ball-and-socket design based on hip replacement implants. From 1970 to 1990, the first generation of cemented prostheses was developed. At that time, trapeziectomy, with tendon interposition or suspension arthroplasty, and Swanson silastic spacers remained the most widely used surgical procedures for thumb basal joint arthritis. From 1990 to 2010, a second generation of cementless prostheses was developed. The third generation was introduced after 2010 and consisted of dual mobility prostheses. In 2020, TMC arthroplasty (simple or dual mobility) is a reliable option in thumb basal joint arthritis with an implant survival rate of 90% at 10 years of follow-up, while providing pain relief and restoring strength and mobility. Restoration of the thumb's length corrects most thumb Z-deformities, so the TMC joint prosthesis may be a viable alternative surgical solution to trapeziectomy, which remains the gold standard in English-speaking countries. Moreover, trapeziectomy after failed TMC arthroplasty provides outcomes equivalent to those of primary trapeziectomy.Perivascular adipose tissue (PVAT) is protective and reduces contraction of blood vessels in health. PVAT is composed of adipocytes, multiple types of immune cells and stromal cells. Interleukin (IL)-10, an anti-inflammatory cytokine usually produced by T cells, B cells and macrophages, was identified as one of the highly expressed (mRNA) cytokines in the mesenteric PVAT of healthy rats. One report suggested that exogenous IL-10 causes relaxation of mouse mesenteric arteries, also suggesting that IL-10 maybe a potential anti-contractile factor. Hence, we hypothesized that PVAT-derived IL-10 causes vasorelaxation and/or reduces vasoconstriction, thus contributing to the anti-contractile nature of PVAT in health. Mesenteric arteries from rats and mice expressed the receptor for IL-10 (in tunica intima and media) as determined by immunohistochemistry. Mesenteric resistance arteries for rats and superior mesenteric artery for mice were used for isometric contractility studies. Increasing concentrations [0.4-100 n, respectively) of endogenous IL-10 in males and females. Contrary to our hypothesis, PVAT-derived IL-10 neither caused vasorelaxation nor reduced local vasoconstriction directly/indirectly. Therefore, IL-10 does not contribute to the anti-contractile nature of PVAT in healthy rodents.Protozoan pathogens that cause neglected tropical diseases are a major public health concern in tropical and developing countries. compound W13 in vivo In the course of our ongoing search for new lead compounds as potential antiprotozoal agents, this study aims to perform a bio-guided fractionation of Pituranthos battandieri, using an in vitro assay against Leishmania amazonensis and Trypanosoma cruzi. Two known polyacetylenes, (-)-panaxydiol (1) and (-)-falcarindiol (2) were identified from the ethanolic extract of the aerial parts of P. battandieri as the main bioactive constituents. Compounds 1 and 2 showed similar potency (IC50 values of 5.76 and 5.68 μM, respectively) against L. amazonensis to miltefosine (IC50 value of 6.48 μM), the reference drug, and low toxicity on macrophage cell lines J774. Moreover, compound 1 exhibited moderate activity (IC50 23.24 μM) against T. cruzi. In addition, three known furanocoumarins, 8-geranyloxypsoralen (3), 8-geranyloxy-5-methoxypsoralen (4), and phellopterin (5) were isolated. Their structures were elucidated by NMR and MS analysis. Compounds 1 and 2 are described for the first time in the Pituranthos genus, and this is the first report on their antiprotozoal activity. These results highlight this type of polyacetylenes as an interesting scaffold for the development of novel antiparasitic drugs.
