Work loss among privately insured employees with overweight and obesity in the United States.

Background: Rising obesity rates in the workforce are accompanied by a hidden cost burden to employers due to work productivity loss. Understanding the impact of obesity on work productivity is essential for employers to provide tailored weight loss interventions in the workplace. Objectives: To measure work loss and associated productivity costs among employees with overweight/obesity compared with employees with normal weight. Methods: This retrospective cohort study used the MerativeTM MarketScan® Health and Productivity Management Database to identify adult employees with ≥1 diagnosis code reporting a body mass index (BMI) between 1/1/2015-12/31/2019. Based on the earliest BMI, employees were assigned to normal weight (BMI 19-24.9), overweight (BMI 25-29.9), obesity class 1 (BMI 30-34.9), obesity class 2 (BMI 35-39.9), and obesity class 3 (BMI ≥40) cohorts. Among employees with data for each work loss category (absenteeism, short-term disability [STD], long-term disability [LTD], worker's compensation [WC]) during the 12-month follow-up, the percentage of employees with work loss, number of hours/days lost, and associated productivity costs were reported. Results: 719,482 employees (normal weight: 106,631, overweight: 230,637, obesity class 1: 185,850, obesity class 2: 101,909, obesity class 3: 94,455) were included. Outcomes increased with each higher BMI category for the mean number of absence hours ([in order of BMI category]: 262, 273, 285, 290, 304) and percentage of employees with a claim (STD: 6.8%, 7.6%, 9.7%, 11.7%, 17.0%; LTD: 0.4%, 0.4%, 0.5%, 0.6%, 0.8%; WC: 2.7%, 2.8%, 3.4%, 3.6%, 3.5%). Estimated costs to the employer associated with absenteeism, STD, LTD, and WC were $1,036, $611, $38, and $95 higher per year (respectively) in the obesity class 3 cohort relative to the normal weight cohort. Conclusions: This real-world analysis demonstrated that employees with overweight/obesity had higher loss of work productivity compared with employees with normal weight. Further studies are warranted to determine the long-term impacts on work productivity loss if overweight and obesity are left untreated.

Unrestricted Learning Opportunities for Trainees in Behavior Analysis: A Survey of Current Practices.

Individuals seeking certification as a board certified behavior analyst (BCBA) by the Behavior Analyst Certification Board (BACB) must meet certain eligibility requirements. In addition to passing the BCBA examination, such requirements include completion of a master's degree, behavior-analytic coursework, and supervised practical fieldwork. In accruing fieldwork hours, trainees must be provided with the opportunity to complete unrestricted activities. The BACB defines unrestricted activities as ". . . those that are most likely to be performed by a BCBA," and requires that 60% of fieldwork hours are comprised of these activities (BACB, 2022b). Fieldwork hours may be accrued across a number of different host sites (e.g., hospital units, schools, community locations), with each host site having different day-to-day responsibilities affecting how these opportunities are provided. Therefore, exploration of the provision of these opportunities and the barriers to providing these opportunities is warranted. The current study sought to determine the current practices involved in provision of opportunities to gain fieldwork experience hours towards BCBA certification; in particular, practices related to unrestricted fieldwork activities. Results indicate that, although unrestricted learning opportunities are often provided to trainees, contingencies present within the day-to-day operations of a clinical environment can be hampering. A discussion of the implications of these barriers and potential solutions are included.

Use of dairy industry side-stream lactose for tablet manufacturing - proof of concept study.

During recent years there have been shortages of certain drugs due to problems in raw material supply. These are often related to active ingredients but could also affect excipients. Lactose is one of the most used excipients in tableting and comes in two anomeric and several solid-state forms. The aim of this study was to utilize lactose from a dairy side-stream and compare it against a commercial reference in direct compression. This would be a sustainable option and would secure domestic availability during crises. Two types of lactose, spray-dried and freeze-dried, were evaluated. Lactose was mixed with microcrystalline cellulose in different ratios together with lubricant and glidant, and flowability and tabletability of the formulations was characterized. The fully amorphous and small particle-sized spray-dried lactose flowed inadequately but exhibited good tabletability. The larger particle-sized, freeze-dried lactose exhibited sufficient flow and better tabletability than the commercial reference. However, disintegration and drug release were slower when using the investigational lactose formulations. This was most likely due to remaining milk proteins, especially caseins, in the lactose. Overall, the investigational lactose provides promise for the use of such a side-stream product during crisis situations but enhancing their properties and/or purity would be needed.

Long-term follow-up of patients with intermediate-risk neuroblastoma treated with response- and biology-based therapy: A report from the Children's Oncology Group study ANBL0531.

BACKGROUND: We previously reported excellent three-year overall survival (OS) for patients with newly diagnosed intermediate-risk neuroblastoma treated with a biology- and response-based algorithm on the Children's Oncology Group study ANBL0531. We now present the long-term follow-up results. METHODS: All patients who met the age, stage, and tumor biology criteria for intermediate-risk neuroblastoma were eligible. Treatment was based on prognostic biomarkers and overall response. Event-free survival (EFS) and OS were estimated by the Kaplan-Meier method. RESULTS: The 10-year EFS and OS for the entire study cohort (n = 404) were 82.0% (95% confidence interval (CI), 77.2%-86.9%) and 94.7% (95% CI, 91.8%-97.5%), respectively. International Neuroblastoma Staging System stage 4 patients (n = 133) had inferior OS compared with non-stage 4 patients (n = 271; 10-year OS: 90.8% [95% CI, 84.5%-97.0%] vs 96.6% [95% CI, 93.9%-99.4%], p = .02). Infants with stage 4 tumors with ≥1 unfavorable biological feature (n = 47) had inferior EFS compared with those with favorable biology (n = 61; 10-year EFS: 66.8% [95% CI, 50.4%-83.3%] vs 86.9% [95% CI, 76.0%-97.8%], p = .02); OS did not differ (10-year OS: 84.4% [95% CI, 71.8%-97.0%] vs 95.0% [95% CI, 87.7%-100.0%], p = .08). Inferior EFS but not OS was observed among patients with tumors with (n = 26) versus without (n = 314) 11q loss of heterozygosity (10-year EFS: 68.4% [95% CI, 44.5%-92.2%] vs 83.9% [95% CI, 78.7%-89.2%], p = .03; 10-year OS: 88.0% [95% CI, 72.0%-100.0%] vs 95.7% [95% CI, 92.8%-98.6%], p = .09). CONCLUSIONS: The ANBL0531 trial treatment algorithm resulted in excellent long-term survival. More effective treatments are needed for subsets of patients with unfavorable biology tumors.

Improved HbA1c and body weight in GADA-positive individuals treated with tirzepatide: A post hoc analysis of SURPASS.

CONTEXT: People with clinically diagnosed type 2 diabetes (T2D) but positive anti-glutamic acid decarboxylase autoantibodies (GADA), referred to here as latent autoimmune diabetes in adults (LADA), may experience more rapid glycemic deterioration than those with T2D and may benefit from effective diabetes treatment with additional metabolic benefits. OBJECTIVE: Assess glycated hemoglobin (HbA1c) and body weight (BW) changes associated with tirzepatide in GADA-positive versus GADA-negative participants with clinical T2D diagnosis. DESIGN: Post hoc analyses based on pooled data from SURPASS 2-5, using mixed-model repeated measures from the efficacy analysis set, adjusting for study and baseline covariates including age, sex, baseline values, body mass index (BMI), and GADA status. SETTING: N/A. PATIENTS: N = 3791. INTERVENTION: Tirzepatide (5, 10, 15 mg). MAIN OUTCOME MEASURE(S): Change from baseline in HbA1c at Weeks 40 (SURPASS-2, -3, -5) and 42 (SURPASS-4)by GADA status. RESULTS: In participants with confirmed GADA status, 3671 (96.8%) were GADA-negative and 120 (3.2%) were GADA-positive (76 [63.3%] with low and 44 [36.7%] with high GADA levels). Baseline characteristics were similar between groups, except for slightly lower BMI in GADA-positive versus GADA-negative participants (mean [SD] BMI 32.2 [6.1] versus 33.6 [6.3] kg/m2). At Week 40/42, both groups achieved robust reductions in HbA1c (-2.11% versus -2.32%) and BW (9.2 kg versus -9.6 kg) (p < 0.001, both groups). HbA1c reductions were greater in GADA-negative participants (estimated difference [95% CI]: 0.21% [0.03, 0.39]; p = 0.024) and BW reductions did not differ between groups (0.38 kg [-0.99, 1.75]; p = 0.588). CONCLUSIONS: In this post hoc analysis, tirzepatide was associated with substantial reductions in HbA1c and BW irrespective of GADA status in adults diagnosed with T2D, suggesting that tirzepatide may improve glycemic control in individuals with LADA.

Early-Onset Type 2 Diabetes and Tirzepatide Treatment: A Post Hoc Analysis From the SURPASS Clinical Trial Program.

OBJECTIVE: We evaluated baseline characteristics of participants with early-onset type 2 diabetes (T2D) from the SURPASS program and tirzepatide's effects on glycemic control, body weight (BW), and cardiometabolic markers. RESEARCH DESIGN AND METHODS: This post hoc analysis compared baseline characteristics and changes in mean HbA1c, BW, waist circumference (WC), lipids, and blood pressure (BP) in 3,792 participants with early-onset versus later-onset T2D at week 40 (A Study of Tirzepatide [LY3298176] in Participants With Type 2 Diabetes Not Controlled With Diet and Exercise Alone [SURPASS-1] and A Study of Tirzepatide [LY3298176] Versus Semaglutide Once Weekly as Add-on Therapy to Metformin in Participants With Type 2 Diabetes [SURPASS-2]) or week 52 (A Study of Tirzepatide [LY3298176] Versus Insulin Degludec in Participants With Type 2 Diabetes [SURPASS-3]). Analyses were performed by study on data from participants while on assigned treatment without rescue medication in case of persistent hyperglycemia. RESULTS: At baseline in SURPASS-2, participants with early-onset versus later-onset T2D were younger with longer diabetes duration (9 vs. 7 years, P < 0.001) higher glycemic levels (8.5% vs. 8.2%, P < 0.001), higher BW (97 vs. 93 kg, P < 0.001) and BMI (35 vs. 34 kg/m2, P < 0.001), and a similarly abnormal lipid profile (e.g., triglycerides 167 vs. 156 mg/dL). At week 40, similar improvements in HbA1c (-2.6% vs. -2.4%), BW (-14 vs. -13 kg), WC (-10 vs. -10 cm), triglycerides (-26% vs. -24%), HDL (7% vs. 7%), and systolic BP (-6 vs. -7 mmHg) were observed in both subgroups with tirzepatide. CONCLUSIONS: Despite younger age, participants with early-onset T2D from the SURPASS program had higher glycemic levels and worse overall metabolic health at baseline versus those with later-onset T2D. In this post hoc analysis, similar improvements in HbA1c, BW, and cardiometabolic markers were observed with tirzepatide, irrespective of age at T2D diagnosis. Future studies are needed to determine long-term outcomes of tirzepatide in early-onset T2D.

Epstein-Barr virus-associated post-transplant lymphoproliferative disorders in pediatric transplantation: A prospective multicenter study in the United States.

BACKGROUND: Epstein-Barr virus (EBV)-associated post-transplant lymphoproliferative disorders (PTLD) is the most common malignancy in children after transplant; however, difficulties for early detection may worsen the prognosis. METHODS: The prospective, multicenter, study enrolled 944 children (≤21 years of age). Of these, 872 received liver, heart, kidney, intestinal, or multivisceral transplants in seven US centers between 2014 and 2019 (NCT02182986). In total, 34 pediatric EBV+ PTLD (3.9%) were identified by biopsy. Variables included sex, age, race, ethnicity, transplanted organ, EBV viral load, pre-transplant EBV serology, immunosuppression, response to chemotherapy and rituximab, and histopathological diagnosis. RESULTS: The uni-/multivariable competing risk analyses revealed the combination of EBV-seropositive donor and EBV-naïve recipient (D+R-) was a significant risk factor for PTLD development (sub-hazard ratio: 2.79 [1.34-5.78], p = .006) and EBV DNAemia (2.65 [1.72-4.09], p < .001). Patients with D+R- were significantly more associated with monomorphic/polymorphic PTLD than those with the other combinations (p = .02). Patients with monomorphic/polymorphic PTLD (n = 21) had significantly more EBV DNAemia than non-PTLD patients (p < .001) and an earlier clinical presentation of PTLD than patients with hyperplasias (p < .001), within 6-month post-transplant. Among non-liver transplant recipients, monomorphic/polymorphic PTLD were significantly more frequent than hyperplasias in patients ≥5 years of age at transplant (p = .01). CONCLUSIONS: D+R- is a risk factor for PTLD and EBV DNAemia and associated with the incidence of monomorphic/polymorphic PTLD. Intensive follow-up of EBV viral load within 6-month post-transplant, especially for patients with D+R- and/or non-liver transplant recipients ≥5 years of age at transplant, may help detect monomorphic/polymorphic PTLD early in pediatric transplant.

Metabotropic Glutamate Receptor 4 (mGlu4) Positive Allosteric Modulators Lack Efficacy in Rat and Marmoset Models of L-DOPA-Induced Dyskinesia.

Background: Increased activity across corticostriatal glutamatergic synapses may contribute to L-DOPA-induced dyskinesia in Parkinson's disease. Given the weak efficacy and side-effect profile of amantadine, alternative strategies to reduce glutamate transmission are being investigated. Metabotropic glutamate receptor 4 (mGlu4) is a promising target since its activation would reduce glutamate release. Objective: We hypothesized that two mGlu4 positive allosteric modulators, Lu AF21934 ((1 S,2 R)-N1-(3,4-dichlorophenyl)cyclohexane-1,2-dicarboxamide) and ADX88178 (5-Methyl-N-(4-methylpyrimidin-2-yl)-4-(1H-pyrazol-4-yl)thiazol-2-amine), would provide relief in rat and primate models of L-DOPA-induced dyskinesia. Methods: The ability of Lu AF21934 or ADX88178 to reverse pre-established dyskinesia was examined in L-DOPA-primed 6-hydroxydopamine-lesioned rats expressing abnormal involuntary movements (AIMs) or in 1-methyl-4-phenyl,1,2,3,6-tetrahydropyridine (MPTP)-treated common marmosets expressing L-DOPA-induced dyskinesia. Additionally, the ability of Lu AF21934 to prevent the development of de novo L-DOPA-induced AIMs was explored in the 6-hydroxydopamine-lesioned rats. Results: Neither Lu AF21934 (10 or 30 mg/kg p.o.) nor ADX88178 (10 or 30 mg/kg p.o.) reduced pre-established AIMs in 6-hydroxydopamine-lesioned rats. Similarly, in L-DOPA-primed common marmosets, no reduction in established dyskinesia was observed with Lu AF21934 (3 or 10 mg/kg p.o.). Conversely, amantadine significantly reduced (>40%) the expression of dyskinesia in both models. Lu AF21934 also failed to suppress the development of AIMs in 6-hydroxydopamine-lesioned rats. Conclusions: This study found no benefit of mGlu4 positive allosteric modulators in tackling L-DOPA-induced dyskinesia. These findings are concordant with the recent failure of foliglurax in phase II clinical trials supporting the predictive validity of these pre-clinical dyskinesia models, while raising further doubt on the anti-dyskinetic potential of mGlu4 positive allosteric modulators.

Thermodynamic solubility measurement without chemical analysis.

In this work, the optical imaging based single particle analysis (SPA) and the gold standard shake-flask (SF) solubility methods are compared. We show that to analyze pharmaceutical compounds spanning 7 log units in solubility and a diverse chemical space with limited resources, several analytical techniques are required (HPLC-UV, LC-MS, refractometry and UV-Vis spectrometry), whereas solely the SPA method is able to analyze all the same compounds. SPA experiments take only minutes, while for SF, it may take days to reach thermodynamic equilibration. This decreases the time span needed for the solubility experiment from initial preparations to obtaining the result from roughly three days to less than three hours. The optimal particle size for SPA ranges from approximately one to hundreds of microns. Challenges include measuring large particles, very fast dissolving compounds and handling small sample sizes. Inherent exclusion of density from the SPA measurement is a potential source of error for compounds with very low or high density values. The average relative difference of 37 % between the two methods is very good in the realm of solubility, where 400 % interlaboratory reproducibility can be expected.

Multiprofessional heart failure self-development framework.

OBJECTIVE: Heart failure remains a key public health priority across the globe. The median age of people with heart failure admitted to hospital in the UK is 81 years old. Many such patients transcend the standard interventions that are well characterised and evidenced in guidelines, into holistic aspects surrounding frailty, rehabilitation and social care. Previous published competency frameworks in heart failure have focused on the value of doctors, nurses and pharmacists. We aimed to provide an expert consensus on the minimum heart failure-specific competencies necessary for multiple different healthcare professionals, including physiotherapists, occupational therapists, dietitians and cardiac physiologists. METHODS: The document has been developed focussing on four main parts, (1) establishing a project working group of expert professionals, (2) a literature review of previously existing published curricula and competency frameworks, (3) consensus building, which included developing a structure to the framework with ongoing review of the contents to adapt and be inclusive for each specialty and (4) write up and dissemination to widen the impact of the project. RESULTS: The final competency framework displays competencies across seven sections; knowledge (including subheadings on heart failure syndrome, diagnosis and clinical management); general skills; heart failure-specific skills; clinical autonomy; multidisciplinary team working; teaching and education; and research and development. CONCLUSION: People with heart failure can be complex and have needs that require input from a broad range of specialties. This publication focuses on the vital impact of wider multidisciplinary groups and should help define the generic core heart failure-specific competencies needed to support future pipelines of professionals, who regularly interact with and deliver care for patients with heart failure.

Epigenetic and Genetic Differentiation Between Coregonus Species Pairs.

Phenotypic diversification is classically associated with genetic differentiation and gene expression variation. However, increasing evidence suggests that DNA methylation is involved in evolutionary processes due to its phenotypic and transcriptional effects. Methylation can increase mutagenesis and could lead to increased genetic divergence between populations experiencing different environmental conditions for many generations, though there has been minimal empirical research on epigenetically induced mutagenesis in diversification and speciation. Whitefish, freshwater members of the salmonid family, are excellent systems to study phenotypic diversification and speciation due to the repeated divergence of benthic-limnetic species pairs serving as natural replicates. Here we investigate whole genome genetic and epigenetic differentiation between sympatric benthic-limnetic species pairs in lake and European whitefish (Coregonus clupeaformis and Coregonus lavaretus) from four lakes (N = 64). We found considerable, albeit variable, genetic and epigenetic differences between species pairs. All SNP types were enriched at CpG sites supporting the mutagenic nature of DNA methylation, though C>T SNPs were most common. We also found an enrichment of overlaps between outlier SNPs with the 5% highest FST between species and differentially methylated loci. This could possibly represent differentially methylated sites that have caused divergent genetic mutations between species, or divergent selection leading to both genetic and epigenetic variation at these sites. Our results support the hypothesis that DNA methylation contributes to phenotypic divergence and mutagenesis during whitefish speciation.

Gender and Racial Diversity Among Obstetrics and Gynecology Departments and Gynecologic Oncology Divisions in Canada: Are We There Yet?

OBJECTIVES: Gender and racial diversity in academic Canadian departments of obstetrics and gynecology (OBGYN) have not been previously described. We examined gender representation in leadership in academic OBGYN departments and gynecologic oncology (GO) divisions, and determined factors predictive of leadership and promotion including racialized status. METHODS: This cross-sectional study of Canadian residency-affiliated academic OBGYN departments queried institutional websites in January 2021 to compile a list of academic faculty. Subjective gender was assessed using photographs and pronouns, and racialized status was determined using photographs. Logistic regression analyses determined predictive factors for leadership roles. Fassiotto et al. rank equity indices (REI) and Hofler et al. representation ratios were calculated. RESULTS: Within 16 Canadian institutions there were 354 (33.6%) men and 699 (66.4%) women, with 18.3% racialized faculty. Men were more likely to reach full professorship (P < 0.00001) and leadership positions of department chair, vice-chair or division head (P = 0.01). Representation ratios for women in OBGYN were <1 for all administrative leadership positions, and pairwise comparisons of the probability of promotion for women OBGYNs using REI reveal significant disparities between senior and junior administrative leadership and professorial ranks. Racialized physicians were less likely to have attained full professorship (P = 0.002). Ninety-seven academic GOs were identified: 68 (70.1%) were women, 17 (17.5%) racialized. Seven GO divisions (44%) had no racialized members. On multivariate analysis, only year of completion of fellowship was predictive of leadership. CONCLUSION: In academic Canadian OBGYN departments women are underrepresented in leadership and full professor positions. Racialized faculty are underrepresented in full professorship.

Association of age at antiretroviral therapy initiation with CD4 +  : CD8 + ratio recovery among virally suppressed people with HIV.

OBJECTIVE: To investigate the association of age at antiretroviral therapy (ART) initiation with CD4 +  : CD8 + T-cell ratio in virally suppressed people with HIV on long-term ART, and to characterize potential CD4 +  : CD8 + ratio recovery in this population by age. DESIGN: A longitudinal study of people attending an HIV clinic at the Royal Free Hospital NHS Trust, London, who initiated ART between 2001 and 2015, and achieved and maintained HIV-1 viral suppression (viral load <1,000 copies/ml). The association of age group at ART initiation with CD4 +  : CD8 + ratio at 5 and 10 years was assessed. METHODS: Multivariable linear regression was used to investigate the relationship between age at ART initiation and log CD4 +  : CD8 + ratio, adjusting for demographic factors (gender/HIV transmission route, ethnicity), baseline CD4 + count and calendar year. RESULTS: The sample included 1859 people aged 20-78 (75% men, 56% white ethnicity). Overall, median CD4 +  : CD8 + T-cell ratio increased from 0.24 at baseline to 0.77 at year 5 and 0.88 at year 10. Ratios increased among all age groups in unadjusted and adjusted models but increased less among older ages (baseline ages 60-69 and 70-79). Median ratios at year 5 were 0.85, 0.80, 0.72, 0.76, 0.6, and 0.44, respectively, among people aged 20-29, 30-39, 40-49, 50-59, 60-69 and 70-79 years at baseline. CONCLUSION: In a virally suppressed London population, age had a substantial impact on CD4 +  : CD8 + ratio recovery, especially for those starting ART after age 60 years. Results may indicate the level of CD4 +  : CD8 + ratio recovery possible in an HIV-positive, virally suppressed, aging population.

Intraoperative predictors of appendiceal abnormalities in patients with mucinous ovarian neoplasms.

OBJECTIVE: To evaluate intraoperative factors predicting appendiceal pathology during gynecologic oncology surgery for suspected mucinous ovarian neoplasms. METHODS: We conducted a retrospective study on 225 patients with mucinous ovarian neoplasms who underwent surgery for an adnexal mass with concurrent appendectomy between 2000 and 2018. Regression analyses were used to evaluate intraoperative factors, such as frozen section of the ovarian mass and surgeon's impression of the appendix in predicting appendiceal pathology. RESULTS: Most patients (77.8%) had a normal appendix on final pathology. Abnormal appendix cases (n = 26) included: metastasis from high-grade adenocarcinoma of the ovary (n = 1), neuroendocrine tumor of the appendix (n = 4), and low-grade appendiceal mucinous neoplasms (n = 26; 23 associated with a mucinous ovarian adenocarcinoma, 2 with a benign mucinous ovarian cystadenoma, and 1 with a borderline mucinous ovarian tumor). Combining normal intraoperative appearance of the appendix with benign or borderline frozen section yielded a negative predictive value of 85.1%, with 14.9% of patients being misclassified, and 6.0% having a neuroendocrine tumor or low-grade appendiceal neoplasm. CONCLUSION: Benign or borderline frozen section of an ovarian mucinous neoplasm and normal appearing appendix have limited predictive value for appendiceal pathology. Appendectomy with removal of the mesoappendix should be considered in all cases of mucinous ovarian neoplasm, regardless of intraoperative findings.

Genomics for monitoring and understanding species responses to global climate change.

All life forms across the globe are experiencing drastic changes in environmental conditions as a result of global climate change. These environmental changes are happening rapidly, incur substantial socioeconomic costs, pose threats to biodiversity and diminish a species' potential to adapt to future environments. Understanding and monitoring how organisms respond to human-driven climate change is therefore a major priority for the conservation of biodiversity in a rapidly changing environment. Recent developments in genomic, transcriptomic and epigenomic technologies are enabling unprecedented insights into the evolutionary processes and molecular bases of adaptation. This Review summarizes methods that apply and integrate omics tools to experimentally investigate, monitor and predict how species and communities in the wild cope with global climate change, which is by genetically adapting to new environmental conditions, through range shifts or through phenotypic plasticity. We identify advantages and limitations of each method and discuss future research avenues that would improve our understanding of species' evolutionary responses to global climate change, highlighting the need for holistic, multi-omics approaches to ecosystem monitoring during global climate change.

Evaluating equity of access and predictors of minimally invasive hysterectomy for endometrial and cervical cancer from 2000 to 2017 in Ontario, Canada: A population-based cohort study.

INTRODUCTION: We sought to assess the uptake of minimally invasive hysterectomy among patients with endometrial and cervical cancer in Ontario, Canada, and assess the equity of access to minimally invasive surgery (MIS) by evaluating associations with patient, disease, institutional, and provider factors. METHODS: This is a retrospective population-based cohort study of hysterectomy for endometrial and cervical cancer in Ontario (2000-2017). Surgical approach, clinicopathologic, sociodemographic, institutional, and provider factors were identified through administrative databases. Fisher's exact, χ2 , Wilcoxon rank sum, logistic regression, and Cox proportional hazards modeling were used to explore factors associated with MIS. RESULTS: A total of 27 652 patients were included. In total, 6199/24 264 (26%) endometrial and 842/3388 (25%) cervical cancer patients received MIS. The proportion of MIS to open surgeries increased from <0.1% in 2000 to over 55% in 2017 (odds ratio [OR] = 1.31, confidence interval [CI] = 1.28-1.34). Low-income quintile, rurality, low hospital volume, nonacademic hospital, nongynecologic oncology surgeon, and earlier year of surgeon graduation were associated with reduced odds of MIS (OR < 1). CONCLUSIONS: The uptake of MIS hysterectomy increased steadily over the time period. Receipt of MIS is dependent upon multiple social determinants, provider variables, and systems factors. These disparities raise concern for health equity in Ontario and have significant implications for health systems planning and resource allocation.

Factors influencing parents' choice of palliative treatment goals for children with relapsed or refractory neuroblastoma: A multi-site longitudinal survey study.

BACKGROUND: Many parents of children with advanced cancer report curative goals and continue intensive therapies that can compound symptoms and suffering. Factors that influence parents to choose palliation as the primary treatment goal are not well understood. The objective of this study was to examine experiences impacting parents' report of palliative goals adjusted for time. The authors hypothesized that awareness of poor prognosis, recall of oncologists' prognostic disclosure, intensive treatments, and burdensome symptoms and suffering would influence palliative goal-setting. METHODS: The authors collected prospective, longitudinal surveys from parents of children with relapsed/refractory neuroblastoma at nine pediatric cancer centers across the United States, beginning at relapse and continuing every 3 months for 18 months or until death. Hypothesized covariates were examined for possible associations with parental report of palliative goals. Generalized linear mixed models were used to evaluate factors associated with parents' report of palliative goals at different time points. RESULTS: A total of 96 parents completed surveys. Parents were more likely to report a primary goal of palliation when they recalled communication about prognosis by their child's oncologist (odds ratio [OR], 52.48; p = .010). Treatment intensity and previous ineffective therapeutic regimens were not associated with parents' report of palliative goals adjusted for time. A parent who reported new suffering for their child was less likely to report palliative goals (OR, 0.13; p = .008). CONCLUSIONS: Parents of children with poor prognosis cancer may not report palliative goals spontaneously in the setting of treatment-related suffering. Prognostic communication, however, does influence palliative goal-setting. Evidence-based interventions are needed to encourage timely, person-centered prognostic disclosure in the setting of advanced pediatric cancer. PLAIN LANGUAGE SUMMARY: Many parents of children with poor-prognosis cancer continue to pursue curative treatments that may worsen symptoms and suffering. Little is known about which factors influence parents to choose palliative care as their child's main treatment goal. To explore this question, we asked parents of children with advanced neuroblastoma across the United States to complete multiple surveys over time. We found that the intensity of treatment, number of treatments, and suffering from treatment did not influence parents to choose palliative goals. However, when parents remembered their child's oncologist talking about prognosis, they were more likely to choose palliative goals of care.
