Summary: The study introduces a novel regenerative hip implant fabricated through a one-step process based on patient-specific design and load-bearing properties. The implant, made using a flexible, bone-inducing biomaterial and extrusion-assisted 3D printing, shows mechanical stability and degradation resistance. It can be fixed with metallic screws to host bone and withstand physiological loads, even after losing approximately 40% of its initial mass. Overall, the hip implant offers an innovative solution for hip dysplasia treatment with regenerative properties.

Summary: This study aims to provide an updated analysis of the long-term outcomes and metal ion levels of patients with metal-on-metal hip resurfacing (HR) and large-diameter-head (LDH) total hip arthroplasty (THA). The results showed no significant differences in clinical outcomes between the two groups, but the HR group had significantly lower metal ion levels compared with the modular THA group. Both implants demonstrated excellent survivorship, with the Adept HR showing remarkable reliability in young active males. The modular LDH THA, despite being discontinued, exhibited higher reliability and lower failure rate compared to similar withdrawn MoM implants.

Summary: This systematic review investigated the concentration of chromium and cobalt in serum in patients who have undergone total hip arthroplasty (THA). The study found that the concentration of these metals varied depending on the material combinations used and the implant configuration. Patient characteristics and the time elapsed from the surgery did not significantly affect the concentration of these metals in serum. The findings provide important information for understanding the potential risks associated with THA.

Summary: Total hip arthroplasty is a popular and effective surgical intervention for treating hip diseases. The success of the surgery depends on factors such as patient characteristics, surgical technique, and the quality of biomaterials used. Recent studies have assessed the benefits and drawbacks of different biomaterial and friction couples in total hip arthroplasty.

Summary: This study examines the association between endorsement of the model minority stereotype by Asian Americans and mental health, and explores the moderating roles of religion and God representation. The findings suggest that both authoritarian and benevolent God representations play a role in moderating this association. This novel integration of the model minority and religiosity literature has promising implications for professionals working with Asian Americans in Christian settings.

Summary: This study investigated the psychological well-being of Canadian arthroplasty surgeons during the peak of the first wave of the COVID-19 pandemic. The results showed that approximately 38% of the surgeons experienced emotional distress and 29% experienced depression. The main factors contributing to psychological morbidity were concerns about loss of income, emotional conflict, and safety worries. However, the majority of surgeons demonstrated insight into the impact of COVID-19 on their emotional health.

Summary: This study evaluates the ability of PCR to detect clinically relevant bacterial species in lower extremity wound infections and assesses the changes in biodiversity and bacterial load during treatment. The results show that PCR can identify common clinically relevant bacterial species, with variations in detection capacity during different stages of treatment. Culture demonstrated a significant decrease in clinically relevant species from initial debridement to closure, while PCR did not show a significant decrease.

Summary: Hindfoot arthrodesis is often required for end-staged deformities. There is a debate whether a double or triple arthrodesis should be performed. This systematic review found that both double and triple arthrodesis have high fusion rates, but the mean time to fusion is similar. The authors recommend double arthrodesis as the preferred procedure due to its benefits over triple arthrodesis.

Summary: Water-walking insects use capillary forces to climb or descend the meniscus between water surface and a solid object by changing body posture, which inspired the development of autonomous aquatic synthetic systems that can shuttle cargo underground between landing and drop-off sites. By controlling the contact angle of a coacervate sac or hydrogel droplet, cyclic cargo shuttling can occur continuously as long as reactants from the surrounding aqueous phase are not depleted, potentially leading to applications in autonomously driven reaction or delivery systems and micro-/milli-robotics.

Summary: The study aims to investigate the stroke risk factors specific to grade 1 ICA BCVI. It found that persistence of injury may increase the risk of stroke, and some strokes still occurred despite initiation of medical therapy. Repeat imaging is recommended to evaluate the progression or resolution of injury in grade 1 ICA BCVI.

Summary: This study retrospectively reviewed 204 patients (220 hips) who underwent elective total hip arthroplasty (THA) between November 2016 and December 2019. The study analyzed templates from 5 different surgeons and compared the accuracy of preoperative digital templating for different stem designs and surgical approaches. The results showed that the accuracy of femoral component size templating was significantly improved with a single-wedge mid-short stem design. The precision of cup sizing was better in the posterior approach group. Accuracy of templating was found to be dependent on the presence of a calibration marker and the stem design.

Summary: The relaxation and aging processes of spherical nanoparticles at a water-oil interface were studied using grazing incidence X-ray photon correlation spectroscopy. It was observed that weak attractions between the nanoparticles resulted in gel-like structures, while the broad size distribution of the nanoparticles inhibited in-plane ordering. Structural rearrangements occurred through intermittent fluctuations rather than continuous cooperative motions.

Summary: The U.S. Army has developed a tool called R4 for suicide prevention and conducted a 12-month evaluation study to test its effectiveness. The study found that units receiving R4 intervention showed improved outcomes in suicidal behavior measures compared to the control group, although the differences were not significant. Further confirmatory studies are needed to determine the effectiveness of R4 intervention.

Summary: Negative pressure wound therapy with instillation-dwell (NPWTi-d) is an advanced form of negative pressure wound therapy that combines the benefits of instillation and negative pressure. With advancements in drape and foam dressing, NPWTi-d has become more effective in treating orthopaedic trauma wounds. Proper drape application techniques play a crucial role in maximizing the benefits of NPWTi-d.
