Volume Analysis of the Proximal Tibial Metaphysis
Purpose The Vitrea 2 imaging software (Vital Images Inc, Minnetonka, MN) was used for the volume analysis of the proximal tibial metaphysis. Materials and Methods Eighteen computed tomography scans of the proximal tibia were processed through the software, and 3-dimensional imaging of the proximal tibia was reconstructed. Results The volume and area of the proximal tibia that were generated resulted in a mean area of 127 cm2 and a mean volume of 77.2 cm2. Conclusion This study supports the use of the proximal tibial metaphysis as a source of low to moderate volume of autologous bone. When compared with the accepted average volume of 25 cm2, the computed results showed that there could be up to 3 times the amount of bone available in the proximal tibial metaphysis. The reported volume of bone harvested from previous studies was based on need and not the total amount available; subsequently, the results showed the possibility of a larger resource of bone, which provides the surgeon with the volumetrical limits of the proximal tibia metaphysis
Treatment of the Prominent Mandibular Angle by Using a Custom Made Surgical Splint
In this case report, we would like to present an alternative surgical technique for the treatment of the bilateral prominent mandibular angles by using a custom-made resin splint (template). The prefabricated template provided a precise outline for the osteotomy, which alleviated the uncertainty of the osseous cut. Furthermore, masseter muscle myomectomy was not necessary in this case which decreased morbidity, and procedure and recovery time, while assuring a more symmetric outcome

Sex Hormone-Binding Globulin Levels Are Inversely Associated With Nonalcoholic Fatty Liver Disease in HIV-Infected and -Uninfected Men.
BackgroundNonalcoholic fatty liver disease (NAFLD) is a leading cause of liver disease worldwide. Elevated sex hormone-binding globulin (SHBG) levels have been observed in the setting of HIV and may protect against some metabolic disorders. We aimed to investigate whether higher SHBG levels may protect against NAFLD in men with/without HIV.MethodsNAFLD was assessed using noncontrast computed tomography in 530 men in the Multicenter AIDS Cohort Study (MACS) who drank <3 alcoholic drinks/d and were uninfected with chronic hepatitis C or B (340HIV+, 190HIV-). Morning serum samples were tested for SHBG, total testosterone (TT), and adiponectin. Multivariable logistic regression was used to assess associations between HIV, SHBG, TT, adiponectin, and NAFLD.ResultsMedian SHBG was highest among HIV+/NAFLD- men and lowest among HIV-/NAFLD+ men. Adjusted for demographics, HIV, visceral adiposity, HOMA-IR, TT, and PNPLA3 genotype, higher SHBG was associated with lower odds of NAFLD (odds ratio [OR], 0.52 per doubling; 95% confidence interval [CI], 0.34-0.80). In separate multivariable models without SHBG, HIV (OR, 0.46; 95% CI, 0.26-0.79) and higher adiponectin (OR, 0.66 per doubling; 95% CI, 0.49-0.89) were associated with lower NAFLD odds, whereas TT was not significantly associated (OR, 0.74 per doubling; 95% CI, 0.53-1.04). Adjusting for SHBG attenuated the associations of HIV (OR, 0.61; 95% CI, 0.34-1.08) and adiponectin (OR, 0.74; 95% CI, 0.54-1.02) with NAFLD.ConclusionsSHBG levels were higher among HIV+ men, were independently associated with lower NAFLD, and could partially explain the associations of HIV and higher adiponectin with lower NAFLD in our cohort. These findings suggest that SHBG may protect against NAFLD, supporting further prospective and mechanistic studies

‘Your duties are to sweep a floor remotely’: low information quality in job advertisements is a barrier to low-income job-seekers’ successful use of digital platforms
Digital platforms have become central in job search. Job-seekers’ experiences with these platforms, however, is a relatively new research area. This paper presents findings from 27 interviews with US low-income job-seekers. Job-seekers encountered many job ads with low information quality on the platforms they used in their searches. These included ads where important information, such as job pay, duration, hours, location, or requirements were missing, unclear, contradictory, or misleading; ads for unethical or illegal work; and ads that did not correspond to paying work but were designed to lure job-seekers into performing free labor or into scams. While job-seekers developed heuristics to navigate low quality ads, these did not always work, and may have caused job-seekers to miss relevant job opportunities. This paper helps answer an open question in HCI research about barriers to low-income job-seekers’ successful use of digital platforms: one barrier is low information quality job ads
