The presence of cavities is associated with unfavorable prognosis in patients with nontuberculous mycobacterial pulmonary disease (NTM-PD). However, little is known about the characteristics of such cavities and their impact on clinical outcomes. The aim of this study was to investigate the size of cavities and their implications on treatment outcomes and mortality in patients with NTM-PD.

We included patients diagnosed with NTM-PD at Seoul National University Hospital between January 1, 2007, and December 31, 2018. We measured the size of cavities on chest computed tomography scans performed at the time of diagnosis and used multivariable logistic regression and Cox proportional hazards regression analysis to investigate the impact of these measurements on treatment outcomes and mortality.

The study cohort comprised 421 patients (noncavitary, n = 329; cavitary, n = 92) with NTM-PD. During a median follow-up period of 49 months, 118 (35.9%) of the 329 patients with noncavitary and 64 (69.6%) of the 92 patients with cavitary NTM-PD received antibiotic treatment. Cavities >2 cm were associated with worse treatment outcomes (adjusted odds ratio, 0.41; 95% CI, 0.17-0.96) and higher mortality (adjusted hazard ratio, 2.52; 95% CI, 1.09-5.84), while there was no difference in treatment outcomes or mortality between patients with cavities ≤2 cm and patients with noncavitary NTM-PD.

Clinical outcomes are different according to the size of cavities in patients with cavitary NTM-PD; thus, the measurement of the size of cavities could help in making clinical decisions.

We describe inflammatory biomarkers in 17 participants in a pre-exposure prophylaxis trial who seroconverted with very early initiation of antiretroviral therapy. Inflammation peaked at the time of HIV infection and returned to baseline within 6-12 months. Starting antiretroviral therapy very early could help mitigate long-lasting HIV-related inflammation.Social media is an increasingly popular forum for medical education. Many educators, including those in infectious diseases, are now creating and sharing unique and educational patient cases online. Unfortunately, some educators unknowingly threaten patient privacy and open themselves to legal liability. Further, the use of published figures or tables creates risk of copyright infringement. As more and more infectious diseases physicians engage in social media, it is imperative to create best practices to protect both patients and physicians. This summary will define the legal requirements of patient de-identification as well as other practical recommendations as they relate to use of clinical case information, patient images, and attribution of primary references on social media.

The opioid crisis in the United States has led to increasing hospitalizations for drug use-associated infective endocarditis (DUA-IE). Outpatient parenteral antimicrobial therapy (OPAT), the preferred modality for intravenous antibiotics for infective endocarditis, has demonstrated similar outcomes among patients with DUA-IE versus non-DUA-IE, but current studies suffer selection bias. The utilization of OPAT for DUA-IE more generally is not well studied.

This retrospective cohort study compared OPAT use for DUA-IE versus non-DUA-IE in adults hospitalized between January 1, 2015 and September 1, 2019 at 3 urban hospitals. We used multivariable regression analysis to assess the association between DUA-IE and discharge with OPAT, adjusting for clinically significant covariables.

The cohort included 518 patients (126 DUA-IE, 392 non-DUA-IE). Compared to those with non-DUA-IE, DUA-IE patients were younger (53.0 vs 68.2 years,

 < .001) and more commonly undomiciled (9.5% vs 0.3%,

 < .01). Patients s and the healthcare system.HIV infection is associated with premature bone loss. The potential impact of recently updated osteoporosis screening guidelines is unknown. In a population-based cohort, we found low adherence and sex differences among eligible people with HIV.

The 2020 Major League Baseball (MLB) season was drastically altered because of the COVID-19 pandemic. Saracatinib cell line The changes included an extended layoff between March and July as well as a shortened preseason.

To determine the incidence and epidemiology of MLB injuries in the abbreviated 2020 season compared with prior seasons. We hypothesized that there was an increase in the overall injury rate in the 2020 season compared with the 2018-2019 seasons and that it equally affected all body regions.

Descriptive epidemiology study.

The MLB transactions database was queried to find players who had been placed on the injury list between 2018 and 2020. Injuries were categorized into upper extremity, lower extremity, spine/core, and other injuries. Incidence per 1000 athlete-exposures was calculated for the prior 2 seasons (2018-2019) and for the 2020 season separately. Incidence for each category was also calculated separately for pitchers and fielders. Incidence rate ratios (IRRs) and confidence intervals were used toration prior to the start of the season placed athletes at a greater risk of injury when play resumed.

There was a significant increase in injury incidence for both pitchers and fielders in 2020. Injury rates increased in anatomic zones of the upper extremity and spine/core but were not significantly changed in the lower extremity. The overall increase in injury rate suggests that irregular or insufficient sport-specific preparation prior to the start of the season placed athletes at a greater risk of injury when play resumed.

There is currently no consensus regarding the appropriate treatment for postoperative pain after arthroscopic partial meniscectomy (APM). Prescribing a mild non-anti-inflammatory protocol of rescue analgesia may be sufficient to avoid the side effects of opioids or anti-inflammatories.

The purpose was to compare the efficacy of pain reduction after APM in nonarthritic knees using betamethasone or celecoxib as anti-inflammatory analgesics versus acetaminophen or tramadol as rescue analgesics. The hypothesis was that there is no advantage for anti-inflammatories in achieving postoperative immediate pain relief after APM in nonarthritic knees compared with a simple nonopioid treatment.

Cohort study; Level of evidence, 2.

This 3-arm controlled study evaluated postoperative pain levels and analgesic consumption in patients who underwent primary APM (under general anesthesia) at a single institution from December 2018 to December 2019. Patients were prospectively divided into 3 treatment groups (1) betameth was negligible among groups.

During the first 3 postoperative weeks after APM in nonarthritic knees, pain was efficiently controlled by betamethasone or celecoxib; however, pain was also efficiently controlled by minimal consumption of acetaminophen with negligible use of tramadol. Therefore, acetaminophen could be prescribed as an effective first-line postoperative analgesic after APM.

Ulnar collateral ligament (UCL) injuries of the elbow are uncommon in the general population but prevalent in the athletic community, particularly among baseball players. Platelet-rich plasma (PRP) injection therapy has become a popular nonoperative adjuvant treatment for such injuries to help reduce recovery time and avoid surgery.

To analyze patient outcomes by injury severity and identify injury types that responded most favorably and unfavorably to PRP treatment. It was hypothesized that PRP therapy would prove to be most beneficial in the treatment of lower-grade, partial UCL tears and less effective in the treatment of more severe, complete UCL tears.

Cohort study; Level of evidence, 3.

A cohort of 50 patients with UCL injuries in their dominant elbow, diagnosed by MRI (magnetic resonance imaging) arthrogram, underwent PRP therapy in conjunction with an established rehabilitation program. UCL injuries were classified by MRI as low-grade partial tear (Type I), high-grade partial tear (Type II), cpromise when combined with physical therapy and a rehabilitation program. Type III UCL tears demonstrated a high rate of success, although with low cohort numbers. Type IV UCL tears did not appear to respond well to PRP injection therapy and often required surgical intervention or cessation of sport. Therefore, PRP treatment does not appear to be appropriate for patients with complete Type IV UCL tears but may enhance recovery and improve outcomes in throwing athletes with Types I, II, and III UCL injuries.

There is little in vivo data that describe the relationships between patellar tendon orientation, patellar tendon strain, and anterior cruciate ligament (ACL) strain during dynamic activities. Quantifying how the quadriceps load the ACL via the patellar tendon is important for understanding ACL injury mechanisms.

We hypothesized that flexion angle, patellar tendon orientation, and patellar tendon strain influence ACL strain during a single-leg jump. Specifically, we hypothesized that patellar tendon and ACL strains would increase concurrently when the knee is positioned near extension during the jump.

Descriptive laboratory study.

Models of the femur, tibia, ACL, patellar tendon, and quadriceps tendon attachment sites of 8 male participants were generated from magnetic resonance imaging (MRI). High-speed biplanar radiographs during a single-leg jump were obtained. The bone models were registered to the radiographs, thereby reproducing the in vivo positions of the bones, ligament, and tendon attachmentndon when the knee is positioned near extension.

Increased ACL strain when the knee is positioned near extension before landing may be due to quadriceps contraction. Thus, landing with unanticipated timing on an extended knee may increase vulnerability to ACL injury as a taut ligament is more likely to fail.
