Hip Arthroscopy and Its Impact on Performance in National Hockey League Players Using Team-Based Advanced Performance Statistics.

Background: Ice hockey players have a high rate of hip pathology, which can lead to hip arthroscopy. Previous studies have not utilized team-based advanced performance statistics in the setting of hip arthroscopy in National Hockey League (NHL) players.

Purpose/hypothesis: The purpose of this study was to use team-based advanced performance statistics to evaluate postoperative performance after hip arthroscopy in NHL players in comparison with their preoperative performance and matched controls of uninjured skaters.

Isolated Talonavicular Arthrodesis as Treatment for Flexible Progressive Collapsing Foot Deformity: A Case Series.

Background: For the younger, more active patient with flexible symptomatic progressive collapsing foot deformity (PCFD), joint-sparing procedures may be preferred to preserve functional motion. Isolated talonavicular (TN) arthrodesis has been described for treatment of rigid and flexible PCFD for patients that are older and less active whose deformity is still correctable through the TN joint. The purpose of this study was to evaluate radiographic and clinical outcomes in patients with PCFD treated with isolated triplanar correction with a TN joint arthrodesis.

Long-Term Outcomes in Female Patients With Carpometacarpal Arthroplasty and Metacarpophalangeal Fusion Compared With the Unoperated Side or Carpometacarpal Arthroplasty.

Purpose: Patients with carpometacarpal (CMC) osteoarthritis (OA) often present with metacarpophalangeal (MP) hyperextension and/or thenar atrophy. This study hypothesizes that MP fusion (MPF) performed at the time of CMC arthroplasty (CMCA) for patients who have moderate-to-severe thenar atrophy, MP hyperextension >30°, or MP arthritis will have greater long-term pinch strength and improvements in the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score from preoperative values when compared with the unoperated side or those who had CMCA only.

Methods: This study involved a retrospective review of long-term results from patients who underwent either CMCA or CMCA/MPF.

Outcomes of Surgically Treated Purely Ligamentous Stage II Lisfranc Injuries.

Background: Low-energy stage II Lisfranc injuries are rare, and treatment can be operative or nonoperative based on a surgeon's assessment of midfoot stability. No previously published patient-reported outcome measures (PROMs) data for Lisfranc injuries isolates purely ligamentous stage II injuries. The purpose of this study was to analyze PROMs for patients who underwent operative management of stage II Lisfranc injuries.

Outcomes of Nitinol Compression Staples in Tarsometatarsal Fusion.

Background: Tarsometatarsal (TMT) arthrodesis is commonly performed in the management of midfoot arthritis, trauma, or deformity. The purpose of this study was to collect aggregate data (demographic, surgical, and perioperative outcomes) on patients who previously had a TMT fusion with BME compression staples.

Methods: Sixty-six patients underwent TMT fusion with BME compression staples.

PCR-based method using propidium monoazide to distinguish viable from nonviable Bacillus subtilis spores.

This paper describes a molecular-based method which is able to discriminate between viable and inactivated Bacillus subtilis spores by utilizing the DNA-intercalating dye propidium monoazide. The approach should be valuable in our attempt to employ molecular methods to streamline the evaluation of process validation using bacterial endospores.

A thermoactive glucoamylase with biotechnological relevance from the thermoacidophilic Euryarchaeon Thermoplasma acidophilum.

A gene encoding an intracellular glucoamylase was identified in the genome of the extreme thermoacidophilic Archaeon Thermoplasma acidophilum. The gene taGA, consisting of 1,911 bp, was cloned and successfully expressed in Escherichia coli. The recombinant protein was purified 22-fold to homogeneity using heat treatment, anion-exchange chromatography, and gel filtration.

Feasibility of utilizing bioindicators for testing microbial inactivation in sweetpotato purees processed with a continuous-flow microwave system.

Continuous-flow microwave heating has potential in aseptic processing of various food products, including purees from sweetpotatoes and other vegetables. Establishing the feasibility of a new processing technology for achieving commercial sterility requires evaluating microbial inactivation. This study aimed to assess the feasibility of using commercially available plastic pouches of bioindicators containing spores of Geobacillius stearothermophilus ATCC 7953 and Bacillus subtilis ATCC 35021 for evaluating the degree of microbial inactivation achieved in vegetable purees processed in a continuous-flow microwave heating unit.

Genome sequence of Picrophilus torridus and its implications for life around pH 0.

The euryarchaea Picrophilus torridus and Picrophilus oshimae are able to grow around pH 0 at up to 65 degrees C, thus they represent the most thermoacidophilic organisms known. Several features that may contribute to the thermoacidophilic survival strategy of P. torridus were deduced from analysis of its 1.

Isolation and molecular analysis of six taproot expressed genes from sugar beet.

The taproot from sugar beet (Beta vulgaris L.) undergoes a specific developmental process to function as a food storage organ. Suppression Subtractive Hybridization (SSH) was utilized for the isolation of cDNA fragments for taproot expressed genes.
