A Geospatial Analysis of Barriers to Cleft Lip and Palate Care in the United States.

OBJECTIVE: This study evaluates the geospatial distribution of cleft lip and/or cleft palate (CL/P) care in the United States, assesses disparities between families with and without one-hour proximity to CL/P care, and recommends interventions for improving access. DESIGN: We identified American Cleft Palate Craniofacial Association-approved CL/P teams and calculated a one-hour driving radius around each clinic. We then used census data to compare risk factors for developing cleft (i.e., incidence risk factors) and obstacles to care (i.e., access risk factors) between counties with and without one-hour proximity. RESULTS: We identified 187 CL/P teams in 45 states. Most were in the South (n = 60, 32.0%), though children in the Middle Atlantic had the greatest access to care. Alabama, Mississippi, Tennessee, and Kentucky had the least access. Children without access were 39% more likely to have gestational tobacco exposure, 8% more likely to have gestational obesity exposure, and 28% less likely to have health insurance (p < 0.01). Children without access in the South were 29% more likely to have a low birth weight and 46% more likely to be living below the poverty line (p < 0.01). Children with access were twice as likely to live in immigrant families and 7-times more likely to speak English as a second language. CONCLUSIONS: Pronounced disparities affect patients with and without one-hour access to CL/P care. Interventions should address care costs for patients living furthest without access and language barriers for patients with access that speak English as a second language.

Crowdsourcing Attitudes and Beliefs About Upper Extremity Donation in the United States.

Introduction To date, upper extremity transplantation (UET) is the most frequently performed vascularized composite allotransplantation (VCA). Perceptions regarding upper extremity donation among Americans, particularly in veterans and service members (VSMs), are largely unknown. Materials and methods We administered a one-time survey to United States (US)-resident Amazon Mechanical Turk (MTurk) workers aged ≥18 years. Descriptive statistics were used to summarize study data; frequencies and percentages were calculated for categorical variables analyzed by Fischer's exact test and using a two-tailed test assessing the statistical significance of p<0.05. Results A total of 860 respondents completed the study survey. Among these, 529 (61.5%) reported willingness to donate an upper extremity, 152 (17.7%) were undecided, and 179 (20.8%) were unwilling. A significantly higher proportion of those willing to donate were female (66.7%, p=0.009), non-Hispanic (63.9%, p=0.000), White (64.0%, p=0.004), non-religious (71.3%, p=0.001), not a VSM (62.8%, p=0.000), or non-amputees (62.9%, p=0.000). Conclusions Our survey found that being female, non-Hispanic, White, non-religious, non-VSM, or non-amputee was significantly associated with donation willingness. These findings may help guide VCA programs, organ procurement organizations, and researchers in efforts to develop targeted educational materials to broaden the public's knowledge and awareness of VCA donation to further benefit all patients in need of or desiring transplantation.

Crowdsourcing Opinions and Awareness of Upper Extremity Transplantation in the United States.

Introduction As of 2008, the United States had 41,000 people living with upper extremity amputation. This number is projected to reach 300,000 by 2050. Human upper extremity transplantation (HUET) may become a more common treatment option with the potential to significantly improve the quality of life for certain amputees. Awareness and opinions regarding HUET among Americans, particularly in Veterans/Service Members (VSM) affiliates, are largely unknown. Materials and methods We administered a survey on Amazon Mechanical Turk (MTurk) workers. Eligible participants were US citizens aged ≥18 years; MTurk worker selection targeted workers who self-reported being a VSM. We used descriptive statistics to summarize study findings and Fisher's exact and Wilcoxon's rank-sum tests for between-group comparisons. Results The survey was completed by 764 individuals, 604 (79.1%) of whom reported being aware of HUET. Among those familiar versus unfamiliar, a significantly higher proportion were aged ≤35 years (n=385, 64.0% vs. n=86, 53.7%; p=0.017), employed (n=523, 86.6% vs. n=114, 71.3%; p<0.001), and aware of their religion's stance on organ/tissue donation (n=341, 54.5% vs. n=62, 38.8%; p<0.001). Amputees and/or respondents related to an amputee were more likely to be aware of HUET than individuals who were amputation naive (n=211, 90.6% vs. n=393, 74.0%, respectively; p<0.001), as were individuals with a personal or familial military affiliation (n=286, 85.4% with vs. n=318, 74.1% with no affiliation; p<0.001). The most reported HUET information sources were digital media (n=157, 31.2%) and internet (n=137, 27.2%). Conclusions Our survey of MTurk workers found greater awareness of HUET among individuals with a VSM or amputee connection. Our additional findings that the internet and academic sources, such as journals or reputable medical publications, were respondents' preferred sources of HUET information emphasize the importance of vascularized composite allotransplantation (VCA) centers' involvement in creating accurate and accessible content to help educate the public about this treatment.

The Fractured Insurance Landscape of Laser Therapy for Scar Revision.

Fractional laser therapy improves skin texture, range of motion, and quality of life for patients with traumatic scars. Nevertheless, anecdotal evidence suggests declining insurance coverage for laser therapy. We aimed to characterize the landscape of insurance coverage for fractional laser therapy present our six-year reimbursement trends. We cross-sectionally analyzed the 60 largest American health insurers by enrollee size and market share. For each, we identified their laser therapy policy for scar revision and extracted their documentation, prior, and continuing authorization requirements and treatment guidelines. We also collected retrospective institutional claims data from 2017 to 2022 to investigate trends in reimbursement. Of the 60 largest health insurers, we identified 11 (18.3%) policies on scar revision and 40 policies (66.7%) on reconstructive surgery, including scar revision. Nineteen policies considered laser therapy medically necessary with evidence of functional impairment refractory to prior treatment. Three insurers denied laser coverage under any circumstance. Of the 1,531 claims submitted by our institution for burn scar laser therapy, 13.8% were denied. Patients with Medicare (ORadj, 3.78) or Medicaid (ORadj, 2.80) had significantly greater odds of coverage than privately insured patients (p<0.01). There was a 14.5% annual reduction in the odds of reimbursement during the study period (ORadj, 0.86, p < 0.01). Laser therapy is a powerful treatment that is not widely available to patients with traumatic scars. Our institutional data suggest this access may be further eclipsed by decreasing trends in coverage since 2017. Strategies are needed to protect patient access to this life-changing treatment.

Analysis of gender representation, authorship inflation, and institutional affiliation in abstract acceptance: a 5-year study.

Purpose: Our goals were to characterize associations of author number, author gender, and institutional affiliation on ratings and acceptances of abstracts submitted to one surgical education conference over 5 years. Methods: We retrospectively reviewed all abstracts submitted between 2017 and 2021 to the annual meeting of the Association for Surgical Education (ASE). Abstract data included average rater scores, acceptance status, author lists, and institutional affiliations. We cross-referenced last author affiliation with top-40 National Institutes of Health (NIH)-funded institutions and used a gender determination software to code first and last author genders. Results: We analyzed 1,162 abstracts. Higher reviewer scores demonstrated positive, weak associations with more authors [r(1160) = 0.191, p < 0.001] and institutions [r(1160) = 0.182, p < 0.001]. Significantly higher scores were noted for abstracts with last authors affiliated with top-40 NIH-funded institutions [4.18 (SD 0.96) vs. 3.72 (SD 1.12), p < 0.001]. Women were first authors (51.8%) (n = 602) and last authors (35.4%) (n = 411) of the time. Abstracts were rated significantly higher with women rather than men as first authors [3.98 (SD 0.99) vs. 3.82 (SD 1.12), p = 0.011] or last [4.01 (SD 1.04) vs. 3.82 (SD 1.10), p = 0.005]. Across all years, abstracts were accepted more often as podium or plenary presentations when submitted by women first [n = 279, 59.7% (p = 0.002)] or last [n = 183, 38.4% (p = 0.095)] authors. Conclusion: Abstracts whose last authors were affiliated with top-40 NIH-funded institutions received significantly higher scores, possibly indicating increased tangible or intangible resources contributing to research efforts. Abstracts with women first and last authors scored higher and were more frequently invited for plenary and podium presentations.

Dicyano and pyridine derivatives of ß-carotene: synthesis and vibronic, electronic, and photophysical properties.

Density functional theory and time-dependent density functional theory calculations provide pictures of the molecular orbitals involved in the ground and excited states of two cyano derivatives of 8'-apo-ß-caroten-8'-al synthesized via an acid-base-catalyzed Knoevenagel condensation reaction. Population analysis shows that the symmetry-allowed transition, S(0) ((1)A(g)) → S(2) ((1)B(u)) based on the C(2h) symmetry is a HOMO (highest occupied molecular orbital) to LUMO (lowest unoccupied molecular orbital) π → π* transition with electron densities located mostly on the polyene chain. Calculated and actual steady-state absorption spectra show similar features with low-energy peak maxima between 550 and 600 nm.

Dicyano and pyridine derivatives of retinal: synthesis and vibronic, electronic, and photophysical properties.

Two new derivatives of all-trans retinal, one containing a pyridine and a cyanide substituent, all-trans-15-cyano-15'-pyridylretinal (2), and the other containing two cyanide substituents, all-trans-15,15'-dicyanoretinal (3), have been synthesized from all-trans-retinal (1) by the Knoevenagel reaction. Compound 2 crystallizes in the space group P1; compound 3 crystallizes in the space group P2(1)/n. The polyene chains are bowed. The compounds exhibit C[triple bond]N vibrations in the infrared and Raman regions and undergo irreversible oxidations. Compounds 2 and 3 display electronic absorptions with maxima located at 442 and 487 nm and emission peaks located at 583 and 500 nm, respectively. Density Functional Theory and Time Dependent Density Functional Theory calculations reveal that the electronic transition from the HOMO to the LUMO can be associated with the A(g) --> B(u) electronic transition and a peak corresponding to the HOMO --> LUMO+1 transition can be associated with the "cis-peak".

Shaping the System - The DRG Evaluation Project of the German Society for Gynaecology and Obstetrics (Deutsche Gesellschaft für Gynäkologie und Geburtshilfe, DGGG).

Introduction: The German DRG system is annually adapted to the changing services provided. For the further development, the self-governing body and its DRG Institute (InEK) depend on participation of the users. Methods: For one of the DRG evaluation projects initiated by DGGG, cost and performance data for the year 2011 from 16 hospitals were available. After plausibility checks and corrections, analyses for service and cost homogeneity were performed. In cases of inadequate DRG-representation attributes were sought that would make an appropriate reimbursement possible. Conspicuities and potential solutions were checked for clinical plausibility. Results: 44 concrete modification proposals for further development of the G-DRG system were formulated and submitted in due time to the InEK. In addition, 3 modification proposals were addressed to the German Institute for Medical Documentation and Information (Deutsches Institut für Medizinische Dokumentation und Information, DIMDI) for further development of the diagnosis classification ICD-10-GM. For all modification proposals care was taken to minimise misdirected incentives and to reduce the potential for disputes with the cost bearers and their auditors services in settlements. Discussion: The publication of the G-DRG system 2014 shows which modification proposals have been realised. Essentially, an appropriate redistribution of the resources among the gynaecological and obstetrics departments is to be expected. The financial pressure that is caused by the generally inadequate financing of hospitals will not be reduced by a further development of the G-DRG system.

Candidaemia in a European Paediatric University Hospital: a 10-year observational study.

In this retrospective observational study covering 1998 to 2008, 32 patients (mean age: 7.50 years) were identified that had 35 episodes of candidaemia (0.47 cases/1000 hospital discharges). Cancer/allogeneic haematopoietic stem cell transplantation (43%) and congenital malformations/syndromes (21%) were the predominant underlying conditions. Central venous catheterization (90%), a history of antibacterial therapy (69%) and previous bacteraemia (54%) were frequent comorbidities. Candida albicans (46%) was most common, followed by Candida parapsilosis (17%) and Candida glabrata (14%). Resistance was infrequent and limited to non-albicans Candida spp. The 30-day and 100-day mortality rates were 11.4%.

Characteristics of hospital patients colonized with livestock-associated meticillin-resistant Staphylococcus aureus (MRSA) CC398 versus other MRSA clones.

Meticillin-resistant Staphylococcus aureus (MRSA) associated with the clonal complex (CC) 398 has emerged among livestock and humans exposed to these animals. MRSA CC398 has so far contributed relatively little to spread of MRSA and the burden of disease in the healthcare setting. This study aimed to assess whether demographic and clinical differences in patients colonized with MRSA CC398 and those carrying other MRSA clones contribute to the observed differences in transmission and infection rates. Age, sex, length of stay (LOS), diagnoses and medical procedures were assessed in all patients with MRSA admitted to a university hospital in 2008 and 2009. S. aureus protein A gene (spa) typing was performed on the first MRSA isolate from each patient. Patients colonized or infected with MRSA that had spa types indicative of CC398 (MRSA CC398) were compared with patients who had other MRSA clones (MRSA non-CC398). Age (53 vs 59 years), mean LOS (8 vs 13 days) and percentage of patients admitted to an intensive care unit (12% vs 17%) differed significantly between MRSA CC398 and MRSA non-CC398 patients, respectively. The mean numbers and types of diagnoses and medical procedures performed for patients in these two groups also differed significantly. The differences in patient characteristics could explain, at least in part, the relatively low rates of transmission and infection associated with MRSA CC398 in the healthcare setting.
