RESUMO
Syndromic polymerase chain reaction (PCR) panels are used to test for pathogens that can cause rash illnesses, including measles. Rash illnesses have infectious and noninfectious causes, and approximately 5% of persons experience a rash 7-10 days after receipt of a measles, mumps, and rubella (MMR) vaccine. MMR vaccine includes live attenuated measles virus, which is detectable by PCR tests. No evidence exists of person-to-person transmission of measles vaccine virus, and illness does not typically result among immunocompetent persons. During September 2022-January 2023, the Tennessee Department of Health received two reports of measles detected by syndromic PCR panels. Both reports involved children (aged 1 and 6 years) without known risk factors for measles, who were evaluated for rash that occurred 11-13 days after routine MMR vaccination. After public health responses in Tennessee determined that both PCR panels had detected measles vaccine virus, six state health departments collaborated to assess the frequency and characteristics of persons receiving a positive measles PCR panel test result in the United States. Information was retrospectively collected from a commercial laboratory testing for measles in syndromic multiplex PCR panels. During May 2022-April 2023, among 1,548 syndromic PCR panels, 17 (1.1%) returned positive test results for measles virus. Among 14 persons who received a positive test result and for whom vaccination and case investigation information were available, all had received MMR vaccine a median of 12 days before specimen collection, and none had known risk factors for acquiring measles. All positive PCR results were attributed to detection of measles vaccine virus. Increased awareness among health care providers about potential measles detection by PCR after vaccination is needed. Any detection of measles virus by syndromic PCR testing should be immediately reported to public health agencies, which can use measles vaccination history and assessment of risk factors to determine the appropriate public health response. If a person recently received MMR vaccine and has no risk factors for acquiring measles, additional public health response is likely unnecessary.

BACKGROUND: Advances in total hip arthroplasty (THA) have resulted in evolving revision indications and intraoperative techniques, which can influence the exposure of trainees to complex cases. We report 3 decades of revision experience from a tertiary referral center that trains fellows, comparing the reasons for revision and the complexity of revisions over time. METHODS: We retrospectively reviewed all revision THAs performed at our institution from 1990 to 2022. Revision diagnoses, components revised, types of revision implants used, and exposure techniques were collected. A "complex" revision was defined as a case that involved an extended trochanteric osteotomy, triflange and cup-cage construct, or acetabular augment. RESULTS: A total of 3,556 THA revisions were identified (108 revisions/year). Aseptic loosening was the most common indication in 1990 to 1999 (45 per year), but decreased to 28.3/year in 2010 to 2019. From 1990 to 1999 and 2010 to 2019, fracture increased from 3.1 to 7.3 per year, infection from 2.9/year to 16.9/year, and metallosis from 0.1 to 13.2 per year. Both component revision were common from 1990 to 1994 (42.6 per year), while polyethylene exchange was most common in 2010 to 2019 (43.3 per year). A decrease was observed in "complex" cases over time: 14.8 extended trochanteric osteotomies/year in 2000 to 2004 compared to 5.4 per year in 2018 to 2022, 4.5 triflange and cup-cage constructs/year in 2004 to 2007 compared to 0.8 per year in 2018 to 2022, and 4 acetabular augments per year in 2009 to 2012 compared to 1 per year in 2018 to 2022. CONCLUSIONS: Indications for revision have changed over the decades, while the number of "complex" revisions has gradually decreased, presumably due to advances in implants and materials. If this trend extends to other training institutions, the next generation of arthroplasty surgeons will have less exposure to complex revisions during their training.

This commentary argues against the indictment of current experimental practices such as piecemeal testing, and the proposed integrated experiment design (IED) approach, which we see as yet another attempt at automating scientific thinking. We identify a number of undesirable features of IED that lead us to believe that its broad application will hinder scientific progress.

Many livestock and human vaccines are leaky because they block symptoms but do not prevent infection or onward transmission. This leakiness is concerning because it increases vaccination coverage required to prevent disease spread and can promote evolution of increased pathogen virulence. Despite leakiness, vaccination may reduce pathogen load, affecting disease transmission dynamics. However, the impacts on post-transmission disease development and infectiousness in contact individuals are unknown. Here, we use transmission experiments involving Marek disease virus (MDV) in chickens to show that vaccination with a leaky vaccine substantially reduces viral load in both vaccinated individuals and unvaccinated contact individuals they infect. Consequently, contact birds are less likely to develop disease symptoms or die, show less severe symptoms, and shed less infectious virus themselves, when infected by vaccinated birds. These results highlight that even partial vaccination with a leaky vaccine can have unforeseen positive consequences in controlling the spread and symptoms of disease.

Influenza seasons typically begin in October and peak between December and February (1); however, the 2022-23 influenza season in Tennessee began in late September and was characterized by high pediatric hospitalization rates during November. This report describes a field investigation conducted in Tennessee during November 2022, following reports of increasing influenza hospitalizations. Data from surveillance networks, patient surveys, and whole genome sequencing of influenza virus specimens were analyzed to assess influenza activity and secondary illness risk. Influenza activity increased earlier than usual among all age groups, and rates of influenza-associated hospitalization among children were high in November, reaching 12.6 per 100,000 in children aged <5 years, comparable to peak levels typically seen in high-severity seasons. Circulating influenza viruses were genetically similar to vaccine components. Among persons who received testing for influenza at outpatient clinics, children were twice as likely to receive a positive influenza test result as were adults. Among household contacts exposed to someone with influenza, children were more than twice as likely to become ill compared with adults. As the influenza season continues, it is important for all persons, especially those at higher risk for severe disease, to protect themselves from influenza. To prevent influenza and severe influenza complications, all persons aged ≥6 months should get vaccinated, avoid contact with ill persons, and take influenza antivirals if recommended and prescribed.

OBJECTIVES: Cost-effectiveness analysis of two 12-week contingency management (CM) schedules targeting heroin abstinence or attendance at weekly keyworker appointments for opioid agonist treatment compared with treatment as usual (TAU). METHODS: A cost-effectiveness analysis was conducted alongside a cluster randomized trial of 552 patients from 34 clusters (drug treatment clinics) randomly allocated 1:1:1 to opioid agonist treatment plus weekly keyworker appointments with (1) CM targeted at heroin abstinence (CM abstinence), (2) CM targeted at on-time attendance at weekly appointments (CM attendance), or (3) no CM (TAU). The primary cost-effectiveness analysis at 24 weeks after randomization took a societal cost perspective with effects measured in heroin-negative urine samples. RESULTS: At 24 weeks, mean differences in weekly heroin-negative urine results compared with TAU were 0.252 (95% confidence interval [CI] -0.397 to 0.901) for CM abstinence and 0.089 (95% CI -0.223 to 0.402) for CM attendance. Mean differences in costs were £2562 (95% CI £32-£5092) for CM abstinence and £317 (95% CI -£882 to £1518) for CM attendance. Incremental cost-effectiveness ratios were £10 167 per additional heroin-free urine for CM abstinence and £3562 for CM attendance with low probabilities of cost-effectiveness of 3.5% and 36%, respectively. Results were sensitive to timing of follow-up for CM attendance, which dominated TAU (better outcomes, lower costs) at 12 weeks, with an 88.4% probability of being cost-effective. Probability of cost-effectiveness remained low for CM abstinence (8.6%). CONCLUSIONS: Financial incentives targeted toward heroin abstinence and treatment attendance were not cost-effective over the 24-week follow-up. Nevertheless, CM attendance was cost-effective over the treatment period (12 weeks), when participants were receiving keyworker appointments and incentives.

De Neys offers a welcome departure from the dual-process accounts that have dominated theorizing about reasoning. However, we see little justification for retaining the distinction between intuition and deliberation. Instead, reasoning can be treated as a case of multiple-cue decision making. Reasoning phenomena can then be explained by decision-making models that supply the processing details missing from De Neys's framework.

All-terrain vehicles (ATVs) are an ongoing source of orthopaedic trauma in the United States. The National Electronic Injury Surveillance System (NEISS) database was queried for ATV-related extremity trauma from 2010 to 2019. An estimated 31,979 ATV-related injuries present to emergency departments annually without significant variability between years. Patients were predominantly white (63.5%), male (72.2%), and aged 18 - 44 (49.9%). Injury sites frequently included the shoulder (24%), wrist (12.8%), and ankle (11.2%). Fractures were most common followed by strains and sprains. Only 15.5% of injuries occurred on public land. Alcohol use was rarely implicated. Orthopaedic surgeons should be aware that rates of ATV-related musculoskeletal injuries have not changed significantly over the last ten years despite legislative efforts to improve ATV safety. Additionally, safety laws are inconsistent across the US, and many apply to the use of ATVs on public land when a minority of injuries occur on non-public land.

Rabies has rarely been described in Xenarthra, and rabies vaccine response has not been documented. A southern tamandua (Tamandua tetradactyla) presented with nonspecific clinical signs and was euthanatized. Subsequently, immunohistochemistry and RT-PCR confirmed a rabies diagnosis. Following these tests, a group of eight captive tamanduas were vaccinated with a killed rabies vaccine, and titers were measured at the time of vaccination and 23 d later. One animal had day 0 titers suggestive of previous vaccination or exposure. All animals had detectable neutralizing rabies virus antibody titers after vaccination, but one animal failed to meet the World Organization for Animal Health's definition for adequate vaccination (≥0.5 IU/ml), and two other animals had low antibody titers (0.56 and 0.6 IU/ml). Rabies should be considered as a possible cause of illness in tamanduas, and rabies vaccination may be a useful preventative measure when anthropic interaction through medical care or ambassador roles is occurring.

On August 16, 2021, the Tennessee Department of Health (TDH) was notified of a positive rabies test result from a South American collared anteater (Tamandua tetradactyla) in Washington County, Tennessee. Tamanduas, or lesser anteaters, are a species of anteater in which rabies has not previously been reported. The animal was living at a Tennessee zoo and had been recently translocated from a zoo in Virginia. TDH conducted an investigation to confirm the rabies result, characterize the rabies variant, and ascertain an exposure risk assessment among persons who came into contact with the tamandua. Risk assessments for 22 persons were completed to determine the need for rabies postexposure prophylaxis (rPEP); rPEP was recommended for 13 persons, all of whom agreed to receive it. Using phylogenetic results of the virus isolated from the tamandua and knowledge of rabies epidemiology, public health officials determined that the animal was likely exposed to wild raccoons present at the Virginia zoo. This report describes expansion of the wide mammalian species diversity susceptible to rabies virus infection and summarizes the investigation, highlighting coordination among veterinary and human public health partners and the importance of preexposure rabies vaccination for animal handlers and exotic zoo animals.

BACKGROUND: Previous radical prostatectomy (RP) is considered a relative contraindication to the laparoscopic approach for inguinal hernia repair (LIHR). This study aimed to compare feasibility, safety and outcomes for patients undergoing totally extraperitoneal (TEP) LIHR who have previously undergone RP. METHODS: This single surgeon, case-control study was performed using a prospective database of all patients undergoing TEP LIHR between 1995 and 2020. Patients who underwent previous RP were identified and compared to matched controls. Pre-operative, operative and post-operative data were analysed. The type of RP, open, laparoscopic or robotic, was identified and operative outcomes compared between the three groups. RESULTS: 6532 LIHR cases were identified. 165 had previously undergone RP and 6367 had undergone primary LIHR without prior RP. The groups were matched for age, demographics and co-morbidities. All operations were commenced laparoscopically, three converted to open in the LIHR + RP group and none in the LIHR group. Median operative time in patients with previous RP was longer, for unilateral (40 min vs. 21 min, p < 0.0001) and bilateral (71 vs. 30 min, p < 0.0001) LIHR. The majority of cases were performed as day stay procedures. There was no difference in immediate recovery parameters including time to discharge, complication rates, return to normal function, return to driving or post-operative analgesia. At 3 months of follow-up there was no difference in hernia recurrence for unilateral (2/128 vs 6/2234, p = 0.0658) or bilateral (0/24 vs 3/1490, p ≥ 0.999) LIHR, nor chronic pain as measured by patient awareness or restriction of activity. No differences in operative and post-operative outcomes were identified between the three types of RP, other than difference in operative time (p = 0.0336). CONCLUSIONS: Previous RP should not be an absolute contraindication for TEP LIHR. Although previous RP adds complexity, in experienced hands TEP LIHR can be done safely, with outcomes equivalent to patients who have not previously undergone RP.

PURPOSE: To report mid-term outcomes of active-duty patients with anterior shoulder instability following our technique for double-pulley remplissage (DPR) with concomitant anterior labral repair. METHODS: All consecutive patients from 1/2010 through 12/2016 that underwent DPR by the senior surgeon with complete outcome scores were identified. All patients had experienced a shoulder dislocation following a traumatic event, and had subsequent instability recalcitrant to conservative management. Patients were excluded if they were lost to follow-up (3) of if they underwent stabilization procedures other than DPR (148). Outcome measures were completed by patients within 1 week prior to surgery and at latest follow-up. Twenty-four patients met the inclusion criteria for the study, and all were active-duty military at the time of surgery. RESULTS: 20/24 (83.3%) patients met the patient acceptable symptomatic state (PASS), while 21/24 (87.5%) achieved substantial clinical benefit (SCB) and 22/24 (91.7%) exceeded the minimal clinically important difference (MCID) for their operative shoulder, as determined by the American Shoulder and Elbow Surgeons (ASES) Score. 21/24 (87.5%) patients met the PASS, while 19/24 (79.2%) achieved SCB and 20/24 (83.3%) exceeded the MCID for their operative shoulder, as determined by the single assessment numeric evaluation (SANE). In addition, 23/24 (95.8%) patients exceeded the MCID for their operative shoulder, as determined by the Rowe Instability score. Preoperative and postoperative range of motion did not vary significantly. All patients had decreased pain postoperatively (P < .0001); 22/24 (91.67%) of patients remained on active-duty status. Failure rate, defined as recurrent subluxation or dislocation, was 4.2%. CONCLUSIONS: Mid-term outcomes in this population of active-duty patients undergoing DPR for shoulder instability without glenoid bone loss demonstrate a statistically and clinically significant improvement in patient-reported outcomes, a significant decrease of pain and an overall return to active-duty rate of 91.67%. LEVEL OF EVIDENCE: IV, therapeutic case series.

PURPOSE: To report short-term outcomes following biceps tenodesis combined with arthroscopic posterior labral repair of type VIII SLAP lesions in active-duty military patients. METHODS: All consecutive patients from January 2012 through December 2018 who underwent biceps tenodesis combined with arthroscopic posterior labral repair of type VIII SLAP tears performed by the senior surgeon with complete outcome scores and minimum 2.5 years follow-up were identified. Exclusion criteria included concomitant glenoid microfracture, rotator cuff repair, or other capsulolabral repair. Outcome measures were completed by patients within 7 days before surgery and at latest follow-up. Biceps tenodesis performed was a mini-open, through a subpectoral approach, using a double-loaded 2.9mm suture-anchor. RESULTS: Thirty-two patients met the inclusion criteria for the study. All patients were active-duty military at time of surgery. Average follow-up was 73.53 ± 22.37 months. Thirty-one patients achieved the minimal clinically important difference, 30 of 32 reached the substantial clinical benefit, and 31 of 32 met the patient acceptable symptomatic state, as defined for the American Shoulder and Elbow Surgeons Shoulder Score. Similarly, 30 of 32 patients reached the minimal clinically important difference, 29 of 32 achieved the substantial clinical benefit, and 32 of 32 met the patient acceptable symptomatic state for the Single Assessment Numeric Evaluation. There were no significant changes in forward flexion, external rotation, or internal rotation between pre- and postoperative measurements. Three patients reported postoperative complications and 1 patient progressed to further surgery. Thirty (93.75%) patients remained on active-duty military service and were able to return to preinjury levels of activity. CONCLUSIONS: Active-duty military patients with type VIII SLAP tears had statistically and clinically significant increases in outcome scores, marked improvement in pain, and high rates of return to unrestricted active-duty following mini-open subpectoral biceps tenodesis combined with posterior labral repair. LEVEL OF EVIDENCE: IV, retrospective case series.

PURPOSE: The purpose of this study is to investigate the outcomes of arthroscopic rotator cuff repair in a severely obese population (body mass index [BMI] > 0 kg/m2) compared to a healthy weight population (BMI 18.5-24.9 kg/m2). METHODS: This study is a retrospective review of prospectively collected data examining the outcomes of arthroscopic rotator cuff repair in both severely obese patients and healthy weight patients. Primary outcome measures analyzed include the American Shoulder and Elbow Surgeons (ASES) Score, the Single Assessment Numeric Evaluation (SANE), pain Visual Analog Scale (VAS), range of motion, and complications. RESULTS: A total of 89 patients met inclusion/exclusion criteria: 52 healthy weight patients (BMI 18.5-24.9 kg/m2) and 37 severely obese patients (BMI >40 kg/m2). Patient-reported pain and functional outcomes had significantly improved after surgery in both groups with regard to the visual analog score (VAS) scores, Single Assessment Numeric Evaluation (SANE) scores, and American Shoulder and Elbow Surgeons Shoulder (ASES) scores (P < .0001). When directly comparing the outcomes in the healthy weight group to the severely obese group, the latter had significantly inferior outcomes in VAS scores (P = .0048), SANE scores (P = .0118), ASES scores (P = .0031), and postoperative internal rotation (P =.0132). At large, these outcomes did not have clinically significant differences. The severely obese group also had higher total numbers of comorbid conditions and longer operative times (P =.0041). CONCLUSIONS: Severely obese patients and their associated comorbid conditions pose unique challenges in rotator cuff tear management, but they still achieve overall excellent outcomes after repair and noninferior clinical differences when compared to healthy weight patients. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

The Food and Drug Administration Egg Safety Rule requires producers with >3000 layer hens to register a Salmonella enterica serotype Enteritidis (SE) prevention plan for production, storage, and transport of shell eggs. Since its implementation began in 2010, four outbreaks of egg-associated salmonellosis have occurred in Tennessee. We reviewed state health department records from each outbreak and described them in the context of the Egg Safety Rule. The outbreaks were linked to three farms that did not meet the criteria for regulation and one farm that was operating in violation of the rule. This regulatory gap poses a food safety risk in Tennessee and nationally. Additional measures at the state and federal level should be considered to address the risk of SE in shell eggs from farms not currently regulated by the Egg Safety Rule.

BACKGROUND: Hand and finger lacerations presenting to U.S. emergency departments (EDs) are common, although the burden of these injuries is not well understood. OBJECTIVE: Our aim is to describe the epidemiology and causes of hand and finger lacerations in U.S. EDs. METHODS: This National Electronic Injury Surveillance System database review investigates hand and finger lacerations presenting to EDs in the United States from 2015 to 2019. RESULTS: Annually, hand and finger lacerations account for 243,844 and 587,451 ED visits, respectively. Affected patients are frequently White (70.5%), male (63.4%), and aged 18 through 44 years (46.3%). The top three products linked to hand and finger lacerations are knives (30.5%), metal containers (4.2%), and drinkware (3.8%), and men are less likely to have injuries from these products than women, especially knives (odds ratio 0.76; 95% confidence interval 0.60-0.96; p < 0.02). Although a minority of hand and finger lacerations involve alcohol (1.2%), men have greater rates of alcohol involvement than women (χ21 = 11.7; p < 0.001). Lacerations frequently occur in the home (61.3%). Many patients (44.2%) present to very large hospitals, and nearly one-half of patients younger than 5 years and one-third of patients aged 5 through 17 years present to pediatric hospitals. Most patients (97.4%) are treated and released without admission and 0.2% are transferred to another hospital. Patients with alcohol, drug, or medication involvement are more likely to leave against medical advice, be admitted, or held for observation (p < 0.001). CONCLUSIONS: Hand and finger lacerations result in a significant number of ED visits. A better understanding of injury trends and presentations can guide injury prevention in manufacturing, education, and public health.

BACKGROUND AND HYPOTHESIS: Transitioning shoulder arthroplasty (SA) from an inpatient to outpatient procedure is associated with increased patient satisfaction and potentially decreased costs; however, concerns exist about complications following same-day discharge. We hypothesized that outpatient SA would be associated with low rates of failed discharges, readmissions, and complications, rendering it a safe and effective option for SA. METHODS: A systematic review of the outpatient SA literature identified 16 of 447 studies with level III and IV evidence that met the inclusion criteria with at least 90 days of follow-up. Data on patient demographic characteristics, preoperative and postoperative protocols, surgery characteristics, failed discharges, complications, and readmissions were collected and pooled for analysis. RESULTS: A total of 990 patients were included in our analysis. Many studies identified specific institutional protocols for determining eligibility for outpatient SA, including preoperative clearance from an anesthesiologist; identification of a perioperative caretaker; and exclusion of patients based on cardiac, pulmonary, or hematologic risk factors. Failed same-day discharge occurred in only 0.9% of patients (7 of 788), and 2.1% of patients (9 of 418) and 0.79% of patients (2 of 252) presented to an emergency department or urgent care facility for a perioperative concern. The readmission rate for periprosthetic fracture, arthrofibrosis, infection, subscapularis rupture, and anterior subluxation was 1.3% (7 of 529 patients). Complications occurred in 7.0% of patients (70 of 990), with 5.4% of patients (53 of 990) experiencing a surgical complication and 1.7% (17 of 990) having a medical complication. There were 28 total reoperations (2.9%, 28 of 955 patients). DISCUSSION AND CONCLUSION: Outpatient SA is associated with low rates of failed discharges, readmissions, and complications. Additionally, the medical and surgical complications that occur after outpatient SA are unlikely to be prevented by the short inpatient stay characteristic of traditional SA. With careful screening measures to identify appropriate candidates for same-day discharge, outpatient SA represents a safe approach to prevent unnecessary hospitalizations and to decrease costs associated with SA.

BACKGROUND: Randomized controlled trials (RCTs) are the gold standard for study design and are considered to have the highest level of evidence. The purpose of this study is to evaluate quality of evidence of prospective RCTs that investigated the clinical efficacy of platelet-rich plasma (PRP) treatments for knee osteoarthritis. We hypothesized that a high level of clinical evidence does not correlate with a high-quality scientific study. MATERIAL AND METHODS: A systematic literature search to identified RCTs that evaluated the efficacy of PRP treatments for knee osteoarthritis. Inclusion criteria included studies that contained key terms "Platelet-rich plasma," "PRP", "knee", and "osteoarthritis". Exclusion criteria excluded studies that were not prospective RCTs. Ten RCTs were evaluated by four independent reviewers. The studies were assessed according to the Oxford Levels of Evidence, a modified Coleman Methodology Score, and the revised Consolidated Standards of Reporting Trials (CONSORT) score. RESULTS: Three of the four Observers rated all 10 studies as Level I, while one Observer rated 80% of the studies as Level I. Using the Coleman Methodology Score, the average score for all studies was 58.0 out of 100 points, designating the studies as "fair." Areas of deficiency included clinical effect measurement and intent-to-treat analysis. Using the CONSORT checklist, the average score was 16.9 out of 22 points, designating the studies as "good". Areas of deficiency included inadequate implementation of randomization and interpretation of results. DISCUSSION: Clinicians should critically evaluate research studies regardless of study design. A sophisticated study design and high level of evidence designation does not guarantee quality research. We determined that RCTs for PRP treatment of knee osteoarthritis were not as robust in quality despite their Level I Oxford Level of Evidence rating.

The precaecocolic fascia, previously known as Jackson's membrane, is a variable vascular peritoneal fold between the ascending colon and the right posterolateral abdominal wall. First described in 1913, it was originally thought to be of developmental or inflammatory origin and associated with abdominal pain. This investigation aimed to review its frequency, form and structure and look for evidence of association with malformation of the bowel, or previous inflammation. 26 dissecting room cadavers were studied to identify the precaecocolic fascia, any malrotation of the colon or signs of previous inflammation: adhesions, surgical scars, or absence of the appendix. Its structure was examined histologically and latex injections were used to trace the arteries. Membranes comparable with previous descriptions of the precaecocolic fascia occurred in 12 of 26 abdomens. They varied in form and size from long and translucent to short, thick, and opaque. In structure, the fascia resembled a fold of peritoneum containing a thickened fibrous lamina. Large thin-walled arteries in the fascia crossed the arteries in the wall of the colon at the point of attachment. No significant association with colonic malrotation or markers of previous inflammation were found. Attention should be paid to the definition of the precaecocolic fascia and "membrane" seems a more appropriate term than "fascia". It is one of a recognized group of peritoneal folds/bands, doubtful in origin but unlikely to be post-inflammatory. It may modify colonic mobility or complicate colonic operations.
