- Abstract
Importance: Inguinal hernia repair in preterm infants is common and is associated with considerable morbidity. Whether the inguinal hernia should be repaired prior to or after discharge from the neonatal intensive care unit is controversial., Objective: To evaluate the safety of early vs late surgical repair for preterm infants with an inguinal hernia., Design, Setting, and Participants: A multicenter randomized clinical trial including preterm infants with inguinal hernia diagnosed during initial hospitalization was conducted between September 2013 and April 2021 at 39 US hospitals. Follow-up was completed on January 3, 2023., Interventions: In the early repair strategy, infants underwent inguinal hernia repair before neonatal intensive care unit discharge. In the late repair strategy, hernia repair was planned after discharge from the neonatal intensive care unit and when the infants were older than 55 weeks' postmenstrual age., Main Outcomes and Measures: The primary outcome was occurrence of any prespecified serious adverse event during the 10-month observation period (determined by a blinded adjudication committee). The secondary outcomes included the total number of days in the hospital during the 10-month observation period., Results: Among the 338 randomized infants (172 in the early repair group and 166 in the late repair group), 320 underwent operative repair (86% were male; 2% were Asian, 30% were Black, 16% were Hispanic, 59% were White, and race and ethnicity were unknown in 9% and 4%, respectively; the mean gestational age at birth was 26.6 weeks [SD, 2.8 weeks]; the mean postnatal age at enrollment was 12 weeks [SD, 5 weeks]). Among 308 infants (91%) with complete data (159 in the early repair group and 149 in the late repair group), 44 (28%) in the early repair group vs 27 (18%) in the late repair group had at least 1 serious adverse event (risk difference, -7.9% [95% credible interval, -16.9% to 0%]; 97% bayesian posterior probability of benefit with late repair). The median number of days in the hospital during the 10-month observation period was 19.0 days (IQR, 9.8 to 35.0 days) in the early repair group vs 16.0 days (IQR, 7.0 to 38.0 days) in the late repair group (82% posterior probability of benefit with late repair). In the prespecified subgroup analyses, the probability that late repair reduced the number of infants with at least 1 serious adverse event was higher in infants with a gestational age younger than 28 weeks and in those with bronchopulmonary dysplasia (99% probability of benefit in each subgroup)., Conclusions and Relevance: Among preterm infants with inguinal hernia, the late repair strategy resulted in fewer infants having at least 1 serious adverse event. These findings support delaying inguinal hernia repair until after initial discharge from the neonatal intensive care unit., Trial Registration: ClinicalTrials.gov Identifier: NCT01678638.

- Abstract
Background: Young workers (aged 15-24 years) experience higher rates of job-related injury compared with workers aged 25-44 years in the United States. Young workers may have limited or no prior work experience or safety training, which can contribute to their injury risk. In 2018, Alaska had the second highest work-related fatality rate and 14th highest non-fatal injury rate in the United States. This study aimed to characterize nonfatal and fatal occupational injuries among young workers in Alaska., Methods: To describe injury patterns among Alaska young workers from 2014-2018, we used data from four datasets: Alaska Workers' Compensation, Alaska Occupational Injury Surveillance System, Alaska Trauma Registry, and Alaska Fishermen's Fund. The datasets were merged two at a time and filtered by the worker characteristics (e.g., age and sex) and incident characteristics (e.g., date of injury). Duplicates were then manually identified between the datasets using the variables above. The injury narrative and Occupational Injury and Illness Classification System codes were used last to verify true duplicates. Descriptive analyses were performed after the duplicates were merged., Results: During the 5-year study period 2014-2018, young workers experienced 20 fatal and 12,886 nonfatal injuries. Residents of Alaska comprised 85% of nonfatal and 70% of fatal injuries. The top three major occupation groups with the highest number of injuries were production (1,391, 14%), food preparation (1,225, 12%), and transportation/material moving (1,166, 11%). The most common events leading to injuries were struck by object or equipment (2,027, 21%), overexertion involving outside sources (1,385, 14%), and struck against object or equipment (905, 9%). The most common nature of injuries were sprains/strains/tears (3,024, 29%), cuts/lacerations (1,955, 19%), and bruises/contusions (1,592, 15%)., Conclusion: Although progress has been made in reducing worker injuries, Alaskan young workers still experience injuries and fatalities frequently. Based on findings, there is a clear need for employers, researchers, public health professionals, parents, and young workers to prioritize young worker safety through an integrated approach, from education and training to adequate workplace supervision and support., (© 2023.

- Abstract
Background: Studies have demonstrated that relative value units (RVUs) do not appropriately reflect cognitive effort or time spent in patient care, but RVU continues to be used as a standardized system to track productivity. It is unknown how well RVU reflects the effort of acute care surgeons. Our objective was to determine if RVUs adequately reflect increased surgeon effort required to treat emergent versus elective patients receiving similar procedures., Methods: A retrospective analysis using The American College of Surgeons' National Surgical Quality Improvement Program 2011 data set was conducted. The control group consisted of patients undergoing elective colectomy, hernia repair, or biliary procedures as identified by Current Procedural Terminology. Comparison was made to emergent cases after being stratified to laparoscopic or open technique. Generalized linear models and logistic regression were used to assess specific outcomes, controlling for demographics and comorbidities of interest. The RVUs, operative time, and length of stay (LOS) were primary variables, with major/minor complications, mortality, and readmissions being evaluated as the relevant outcomes., Results: A total of 442,149 patients in the National Surgical Quality Improvement Program underwent one of the operative procedures of interest; 27,636 biliary (91% laparoscopic; 8.5% open), 28,722 colorectal (40.3% laparoscopic, 59.7% open), and 31,090 hernia (26.6% laparoscopic, 73.4% open) operations. Emergent procedures were found to have average RVU values that were identical to their elective case counterparts. Complication rates were higher and LOS were increased in emergent cases. Odds ratios for complications and readmissions in emergent cases were twice those of elective procedures. Mortality was skewed toward emergent cases., Conclusion: Our data indicate that the emergent operative management for various procedures is similarly valued despite increased LOS, more complications, higher mortality risk, and subsequently increased physician attention. Our findings suggest that the RVU system for acute care surgeons may need to be reevaluated to better capture the additional work involved in emergent patient care.

- Abstract
Purpose: Noninvasive lesions involving the lobules of the breast are increasingly diagnosed as incidental microscopic findings at the time of lumpectomy or core-needle biopsy. We investigated the incidence rates of invasive breast cancer (IBC) after a diagnosis of lobular carcinoma-in-situ (LCIS) by using Surveillance, Epidemiology, and End Results (SEER) data., Patients and Methods: Patients (N = 4,853) having a diagnosis of primary LCIS in the time period of 1973 to 1998 were identified using the SEER Public Use CD-ROM data. The database was then searched for patients with subsequent primary IBC occurrences (n = 350). The clinical and pathologic characteristics of patients with subsequent primary IBCs were compared with the characteristics of patients with primary IBCs attained during the same time period (N = 255,114)., Results: The incidence of IBC increased over time from diagnosis of LCIS, with 7.1% +/- 0.5% incidence of IBC at 10 years. IBCs detected after partial mastectomy occurred in either breast (46% ipsilateral and 54% contralateral); however, after mastectomy, most IBCs were contralateral (94.7%). IBCs occurring after LCIS more often represented invasive lobular histology (23.1%) compared with primary IBCs (6.5%). The standardized incidence ratio (the ratio of observed to expected cases) for developing IBC was 2.4 (95% CI, 2.1 to 2.6) adjusted for age and year of diagnosis., Conclusion: LCIS is associated with increased risk of subsequent invasive disease, with equal predisposition in either breast. The minimum risk of developing IBC after LCIS is 7.1% at 10 years.

- Abstract
Managed competition with prefunding could be a useful approach to long-term care. One version, described here, has two main components: First, people would be required to save over their working lives to cover a portion of the expected cost of a minimum required level of long-term-care insurance. Second, people would begin purchasing long-term-care insurance around the time of retirement from one of a number of competing insurers, under a system of managed competition. Potentially large social gains would arise from improving insurance arrangements, distributing long-term-care costs more equitably across and within generations, and eliminating many of the distortions inherent in the current Medicaid program.

- Abstract
The health status of 239 Ethiopian refugees in the United States was evaluated. Over 70 per cent were males 15-30 years old. Positive PPDs (purified protein derivative of tuberculin) were observed in 72 per cent and 3.4 per cent had abnormal chest x-rays. One patient had active tuberculosis. Other laboratory abnormalities included: intestinal parasites (36.7 per cent), anemia (14.9 per cent), eosinophilia (14 per cent), positive syphilis serology (7.5 per cent), and hepatitis B surface antigenemia (9.4 per cent). The most prevalent intestinal parasites were Giardia lamblia, Trichuris trichiura, and Schistosoma mansoni.
