RESUMO

BACKGROUND: While the importance of interprofessional education in medical training has been well-established, no specific framework has been used uniformly or shown to be most effective in the creation of interprofessional education (IPE) sessions. Further, prior studies have demonstrated that students have preferences for the design of these experiences. In this study, we sought to understand medical student preference for interprofessional teammates and motivations for this choice. METHODS: In this single-institution, cross-sectional analysis of the Duke IPE Clinic, participating students from September 2019-March 2020 completed a voluntary electronic survey that queried preferences for which health professions students (Doctor of Physical Therapy (DPT), Accelerated Bachelor of Science in Nursing (ABSN), Nurse Practitioner (NP), Pharmacy, and Physician's Associate (PA)) they would want to work with, and the motivating reason. Preferences and reasons were compared between first-year medical students (MS1s) and third- and fourth-year medical students (MS3s/MS4s). RESULTS: In total, 132 students participated. We found that MS1s most preferred interprofessional teammates with a more similar area of study (PA, NP), whereas MS3s/MS4s most preferred classmates with a less similar area of study (pharmacy, DPT, ABSN). MS1 students frequently selected their first-choice preference because the profession seemed most similar, while MS3/MS4 students often selected their first-choice preference because the profession seemed most different. CONCLUSIONS: Medical students earlier in training have more interest in working with professions they view as similar whereas senior students prefer to work with professions they view as more different. This information is important for designing educational IPE opportunities.

RESUMO

BACKGROUND: High-risk gestational trophoblastic neoplasia (GTN) is rare and treated with diverse approaches. Limited published institutional data has yet to be systematically reviewed. OBJECTIVES: To compile global high-risk GTN (prognostic score ≥7) cohorts to summarise treatments and outcomes by disease characteristics and primary chemotherapy. SEARCH STRATEGY: MEDLINE, Embase, Scopus, ClinicalTrials.gov and Cochrane were searched through March 2021. SELECTION CRITERIA: Full-text manuscripts reporting mortality among ≥10 high-risk GTN patients. DATA COLLECTION AND ANALYSIS: Binomial proportions were summed, and random-effects meta-analyses performed. MAIN RESULTS: From 1137 records, we included 35 studies, representing 20 countries. Among 2276 unique high-risk GTN patients, 99.7% received chemotherapy, 35.8% surgery and 4.9% radiation. Mortality was 10.9% (243/2236; meta-analysis: 10%, 95% confidence interval [CI] 7-12%) and likelihood of complete response to primary chemotherapy was 79.7% (1506/1890; meta-analysis: 78%, 95% CI: 74-83%). Across 24 reporting studies, modern preferred chemotherapy (EMA/CO or EMA/EP) was associated with lower mortality (overall: 8.8 versus 9.5%; comparative meta-analysis: 8.1 versus 12.4%, OR 0.42, 95% CI: 0.20-0.90%, 14 studies) and higher likelihood of complete response (overall: 76.6 versus 72.8%; comparative meta-analysis: 75.9 versus 60.7%, OR 2.98, 95% CI: 1.06-8.35%, 14 studies), though studies focused on non-preferred regimens reported comparable outcomes. Mortality was increased for ultra-high-risk disease (30 versus 7.5% high-risk; meta-analysis OR 7.44, 95% CI: 4.29-12.9%) and disease following term delivery (20.8 versus 7.3% following molar pregnancy; meta-analysis OR 2.64, 95% CI: 1.10-6.31%). Relapse rate estimates ranged from 3 to 6%. CONCLUSIONS: High-risk GTN is responsive to several chemotherapy regimens, with EMA/CO or EMA/EP associated with improved outcomes. Mortality is increased in patients with ultra-high-risk, relapsed and post-term pregnancy disease.

RESUMO

OBJECTIVE: To assess, using a national surgical outcomes database, the association of various malnutrition definitions with post-operative morbidity in three gynecologic malignancies. METHODS: Patients undergoing resection of ovarian, uterine, or cervical cancer between 2005 and 2019 were identified using the National Surgical Quality Improvement Program (NSQIP) database. Patients were classified based on specific, pre-defined malnutrition criteria: severe malnutrition (Body Mass Index (BMI) <18.5 + 10% weight loss), European Society for Clinical Nutrition and Metabolism ((ESPEN1); BMI 18.5-22 + 10% weight loss), ESPEN2 (BMI < 18.5), American Cancer Society ((ACS); normal/overweight BMI + 10% weight loss), mild malnutrition (BMI 18.5-22), or albumin (<3.5 g/dL). Outcomes included 30-day major complications, readmission, reoperation. Modified Poisson regression estimated associations between definitions and outcomes. RESULTS: Of 76,290 total patients undergoing surgery, those meeting malnutrition definitions were: severe-98 (0.1%), ESPEN1-148 (0.2%), ESPEN2-877 (1.1%), ACS-1028 (1.3%), mild-2853 (3.7%), and albumin (11.1%). Complication rates were: unplanned readmission-5.5%, reoperation-1.7%, major complications-13.5%. For ovarian cancer, ESPEN2 malnutrition was associated with higher readmissions (risk ratio 1.69; 95% confidence interval 1.29-2.20), reoperations (2.53; 1.70-3.77), and complications (1.36; 1.20-1.54). For uterine cancer, ACS malnutrition was associated with readmissions (2.74; 2.09-3.59), reoperations (3.61; 2.29-5.71) and complications (3.92; 3.40-4.53). For cervical cancer, albumin<3.5 g/dL was associated with readmissions (1.48; 1.01-2.19), reoperations (2.25; 1.17-4.34), and complications (2.59; 2.11-3.17). Albumin<3.5 was associated with adverse outcomes in ovarian and uterine cancer. CONCLUSIONS: Preoperative risk assessments might be tailored using cancer-specific malnutrition criteria. Major complications, readmissions, and reoperations are all associated with the ESPEN2 definition for ovarian cancer, the ACS definition for uterine cancer, and with albumin<3.5 for all cancers.

RESUMO

OBJECTIVE: Hepatitis C virus and intrahepatic cholestasis of pregnancy (ICP) are well-known independent risk factors for adverse outcomes in pregnancy. In addition, it is well-established that there is an association between Hepatitis C and ICP. This study's objective was to describe the impact of having both Hepatitis C and ICP on maternal and obstetric outcomes compared to patients having either Hepatitis C or ICP. METHODS: We conducted a retrospective cohort study of the Nationwide Readmissions Database, an all-payor sample of discharges from approximately 60% of US hospitalizations. Deliveries at 24-42+ weeks between 10/2015 and 12/2020 were included. Diagnosis of Hepatitis C and ICP, and outcomes related to severe maternal morbidity were identified using International Classification of Disease-10 codes. Patients were categorized based on Hepatitis C and ICP status. Weighted logistic and negative binomial regression analyses were used to evaluate the association between Hepatitis C and ICP status and outcomes, adjusting for patient and hospital characteristics. The primary outcome was any severe maternal morbidity; secondary outcomes included acute respiratory distress syndrome, acute kidney injury, sepsis, gestational diabetes, cesarean delivery, preterm birth, and hospital length of stay. We modeled interaction terms between ICP and Hepatitis C to assess whether there was a greater or lesser effect from having both conditions on outcomes than we would expect from additive combination of the individual components (i.e., synergy or antagonism). RESULTS: A total of 10,040,850 deliveries between 24-42+ weeks were identified. Of these, 45,368 had Hepatitis C only; 84,582 had ICP only; and 1,967 had both Hepatitis C and ICP. Patients with both Hepatitis C and ICP had 1.5-fold higher odds of developing severe maternal morbidity compared to having neither. There was an also an increased odds of severe maternal morbidity in patients with both Hepatitis C and ICP compared to patients with only Hepatitis C or ICP. Having both was also associated with higher odds of preterm birth and length of stay compared to having only Hepatitis C, only ICP, or neither (preterm birth: aOR 5.09, 95% CI 4.87-5.33 vs. neither; length of stay: 46% mean increase, 95% CI 35-58% vs. neither). Associations were additive-no significant interactions between hepatitis C and cholestasis were found on rates of severe maternal morbidity, acute respiratory distress syndrome, acute kidney injury, sepsis, cesarean section, or preterm birth (all p>0.05), and was minimal for gestational diabetes and length of stay. CONCLUSION: Hepatitis C and ICP are independent, additive risk factors for adverse maternal and obstetric outcomes. Despite physiologic plausibility, no evidence of a synergistic effect of these two diagnoses on outcomes was noted. These data may be useful in counseling patients regarding their increased risk of adverse outcomes when ICP presents in association with Hepatitis C versus ICP alone.

RESUMO

Testosterone has been shown to have dose-dependent effects on spatial memory in males, but the effects of aging upon this relationship remain unclear. Additionally, the mechanism by which testosterone regulates memory is unknown, but may involve changes in brain-derived neurotrophic factor (BDNF) within specific brain regions. We tested the effects of age and testosterone on spatial memory among male rats using two spatial memory tasks: an object-location memory task (OLMT) and the radial-arm maze (RAM). Castration had minimal effect on performance on the RAM, but young rats (2 months) performed significantly fewer working memory errors than aged rats (20 months), and aged rats performed significantly fewer reference memory errors. Both age and castration impaired performance on the OLMT, with only the young rats with intact gonads successfully performing the task. Subsequent experiments involved daily injections of either drug vehicle or one of four doses of testosterone propionate (0.125, 0.250, 0.500, and 1.00 mg/rat) given to castrated aged males. On the RAM, a low physiological dose (0.125 mg) and high doses (0.500-1.000 mg) of testosterone improved working memory, while an intermediate dose (0.250 mg) did not. On the OLMT, only the 0.250 mg T group showed a significant increase in exploration ratios from the exposure trials to the testing trials, indicating that this group remembered the position of the objects. Brain tissue (prefrontal cortex, hippocampus, and striatum) was collected from all subjects to assay BDNF. We found no evidence that testosterone influenced BDNF, indicating that it is unlikely that testosterone regulates spatial memory through changes in BDNF levels.

RESUMO

The ventral tegmental area (VTA) is the origin of the mesolimbic dopaminergic system known to play an integral role in mediating reward and development of drug addiction. Although the differences in neuronal plasticity of VTA at various ages remain to be understood, age is known to influence the effects of chronic opioids. In addition, adaptations associated with exposure to opioids within glial populations located in the VTA are poorly understood. The objective of the study was to determine if there are changes in astrocytic immunofluorescent labeling in the VTA following chronic morphine administration in a rat model at different ages: newborn at postnatal day (PD)7 and adult (estimated PD57). We hypothesized that increased immunohistochemical labeling of an astrocytic marker, glial fibrillary acidic protein (GFAP) in the VTA following chronic administration of morphine will not differ with age. Two groups of rats were analyzed: chronic morphine and saline control treatment groups. Either morphine (10 mg/kg) or equal volume of saline was given subcutaneously twice daily for 6½ days. On the 7th day of treatment, animals were anesthetized and perfused at one hour after the final drug injection. Coronal sections of the midbrain were processed for immunofluorescent identification of GFAP that was noted at both ages. We report an increase in both (1) GFAP labeling intensity, as well as (2) the percent area occupied by astrocytes that are immunoreactive for GFAP following chronic morphine when compared to saline treatment in the VTA only for the adults (n=6/group) but not infant rats at PD7 (n=5/group). Our findings suggest that adaptations in the mesolimbic dopaminergic system produced by repeated exposure to opioids may be associated with changes in glial function that differ with age.
