A midfoot strike differentiated Achilles tendon injuries (odds ratio [OR], 2.27; 90% confidence interval [CI], 1.17-4.41) and a forefoot strike distinguished posterior lower leg injuries (OR, 2.59; 90% CI, 1.50-4.47) from the rest of the injured group. Peak vGRF was weakly associated with hip injuries (OR, 1.14; 90% CI, 1.05-1.24). Female sex was associated with injuries to the lower leg (OR, 2.65; 90% CI, 1.45-4.87) and hip/groin (OR, 2.22; 90% CI, 1.43-3.45). Male sex was associated with Achilles tendon injuries (OR, 1.923; 90% CI, 1.094-3.378).

Sex, foot strike pattern, and vGRF were the only factors that distinguished specific injury locations from the remaining injury locations.

Walking speed can be used to identify characteristics of frailty in older adults. It has a strong positive correlation with balancing abilities. The Brief-Balance Evaluation Systems Test (Brief-BESTest) was developed to assess balancing functions of the 6 balance control systems in a short time. However, for community-dwelling older adults, the relationship between walking speed and the Brief-BESTest needs to be clarified. Selleck Abraxane Even the cutoff scores for each Brief-BESTest section should be indicated for physical therapists to use it for effectively evaluating balance deficits. Our objective was to establish cutoff scores for individual Brief-BESTest sections, determine fast or slow walkers in community-dwelling older adults, and investigate the relationship between balance control systems and walking speed.

In a cross-sectional study involving 55 participants 77 years and older, the Brief-BESTest was evaluated after grouping the participants based on their walking speeds in public community centers. We comparow walkers. Section VI was a particularly important balance function measurement that determined the walking speed with the highest accuracy. Therefore, it should be the first focus when physical therapists treat community-dwelling older adults.
Three sections (III, anticipatory postural adjustments; IV, postural responses; and VI, stability in gait) could differentiate between fast and slow walkers. Section VI was a particularly important balance function measurement that determined the walking speed with the highest accuracy. Therefore, it should be the first focus when physical therapists treat community-dwelling older adults.
Tourniquets are widely used during extremity surgery. In order to prevent surgical site infection, correct timing of antimicrobial prophylaxis and tourniquet inflation is important. We aimed to evaluate the time for which the free drug concentration of cefuroxime is maintained above the minimum inhibitory concentration (t > MIC) in porcine subcutaneous adipose tissue and calcaneal cancellous bone during 3 clinically relevant tourniquet application scenarios.

Twenty-four female Danish Landrace pigs were included. Microdialysis catheters were placed bilaterally for sampling of cefuroxime concentrations in calcaneal cancellous bone and subcutaneous adipose tissue, and a tourniquet was applied to a randomly picked leg of each pig. Subsequently, the pigs were randomized into 3 groups to receive 1.5 g of cefuroxime by intravenous injection 15 minutes prior to tourniquet inflation (Group A), 45 minutes prior to tourniquet inflation (Group B), and at the time of tourniquet release (Group C). The tourniquet duricient concentrations in calcaneal cancellous bone and subcutaneous adipose tissue throughout the 90-minute tourniquet application. Furthermore, tourniquet-induced tissue ischemia fully resolved 2.5 hours after tourniquet release.

Cefuroxime administration 15 to 45 minutes prior to tourniquet inflation seems to be a safe window. If the goal is to maintain postoperative cefuroxime concentrations above relevant MIC values, our results suggest that a second dose of cefuroxime should be administered at the time of tourniquet release.

A number of surgical approaches are available for total hip arthroplasty (THA), but there are limited large-volume, multi-surgeon data comparing the rates of early revisions following these approaches. The aim of this study was to compare the rate of revision of primary conventional THA related to surgical approach.

Data from the Australian Orthopaedic Association National Joint Replacement Registry were analyzed for all patients who had undergone a primary THA for osteoarthritis from January 2015 to December 2018. The primary outcome measure was the cumulative percent revision (CPR) for all causes. Secondary outcome measures were major revision (a revision procedure requiring change of the acetabular and/or femoral component) and revision for specific diagnoses fracture, component loosening, infection, and dislocation. Age, sex, body mass index (BMI), American Society of Anesthesiologists (ASA) score, femoral head size, and femoral fixation were assessed as potential confounders.

There was a total of 1 lower rate of revision compared with the lateral approach in the first 6 months only.

There was no difference in the overall early CPR among the surgical approaches, but the anterior approach was associated with a higher rate of early major revisions and femoral complications (revisions for periprosthetic fracture and femoral loosening) compared with the posterior and lateral approaches and with a lower rate of dislocation and infection.

To review emerging evidence specific to abortion care, including diagnostic testing and pain management.

Recent advances in abortion care include improvements in gestational age dating, Rh status testing, and pain management methods. When ultrasound technology is available, the use of crown-rump length (CRL)-based dating is more accurate up to 13 weeks and composite CRL and biometry between 13 and 14 weeks. Evidence supports using updated fetal foot length-to-gestational age reference ranges for postprocedure gestational age confirmation. Serum tests for two placental proteins, pregnancy-associated plasma protein A and a disintegrin and metalloproteinase 12, show potential for identifying pregnancies with gestational age more than 70 days. Early research using flow cytometry demonstrates that fetal RBC exposure after first-trimester uterine aspiration is insufficient to cause maternal Rh-sensitization, supporting elimination of Rh testing and anti-D-immunoglobulin provision prior to 8 weeks gestation. Recent studies exploring pain management strategies have not generated a standardized approach.
