At the Summit on Cancer Health Disparities held in 2023, the session on Access to Cancer Care in Low- and middle- income countries (LMIC) highlighted several efforts globally. The collaborative efforts of Dana Farber Cancer Institute and the Ministry of Health in spearheading the Butaro Cancer Center of Excellence (BCCOE) in Rwanda was one such initiative. They were able to set up the BCCOE to address the unmet need of cancer care in this area and have trained nurses in East Africa to help establish other similar centers. They also serve as the single radiotherapy center for the entire of the country. Another such collaborative effort between Massachusetts General Hospital and the cancer center in Botswana in setting up sexual health education initiatives for women undergoing pelvic radiation was highlighted. They started with a quality improvement project to demonstrate the benefit of sexual health education and proper vaginal dilator use amongst women in this demographic. They were able to demonstrate that 90% of patients were able to complete an in-person 6-week workshop with clear benefits noted on a long-term basis. To highlight examples of best practice examples of equitable partnerships, examples of partnerships between Instituto Nacional de Cancerologia in Mexico City and UCSF was described. It was emphasized that for successful collaborations, equitable bidirectional partnerships are key. The thought leaders in this field also highlighted challenges associated with global oncology and the need for inclusion of minorities in clinical trials to improve cancer care for all globally.

Background: International data on COVID-19 infection in immunosuppressed populations is limited. Heart transplant (OHT) recipients requiring immunotherapy are at risk for potentially increased complications with COVID-19 infection, including long-covid and oxidative stress during initial infection. The availability of vaccination and temporal trends in this population has not been well described. We report outcomes in immunosuppressed patients during the initial years of the COVID pandemic. Methods: All patients who underwent heart transplantation at Mayo Clinic in Florida were reviewed from March 2019 to October 2021. Patients were divided into two groups: those diagnosed with COVID-19 (based on a positive SARS-CoV-2 RT-PCR) and those not. A p value of 0.05 was considered significant using the Chi-squared test. Results: A total of 98 patients were reviewed. Of these, 49 were COVID-19-positive (CP), and 49 were negative (CN). The cohort was well matched, with a median age of 58 years (49 - 65) in both groups. 20 females in the CP group and 9 in the CN group. Diabetic status (p = .07), history of hypertension (p=.5), BMI (p=.41), GFR (p=.19), and ejection fraction (p=.29) were not significantly different between the two groups. Immunosuppression was not significantly different for CP or CN patients, with a median trough tacrolimus level of 7.68 vs. 8.70 (p = .26). The median time from transplant to CP was 384 days (237 - 677). The CN group’s median follow-up after transplant was 947 days (737 - 1191). CP hospitalization rate was 24% (5 Pfizer, 3 unvaccinated, 4 Moderna) with only 1 death. Hospitalized patients’ markers of inflammation were: IL6 19.2 (12-48), D-dimer 1408 (763 - 2227), and CRP 54 (20 - 90). The CP group was more vaccinated than the CN group (92% vs. 78%, p = .025). More CP patients received the Pfizer vaccine compared to Moderna (p = .018). Conclusion: We found that patients after OHT on similar immunotherapy regimens did not carry the same risk of contracting Covid-19 despite being vaccinated. CP patients were generally infected in the first 1.5 years after OHT. This may indicate an increased infection rate due to a weakened immune system or lack of bivalent boosters before 2022. Vaccine efficacy in this population should be evaluated in larger studies.

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia detected in hospitalized patients. It is independently associated with an increased risk of stroke. Anti-fibrotic properties of mineralocorticoid receptor antagonists (MRA) have been proposed to modulate AF burden. Gender differences in patients with AF exist within the epidemiology and causative mechanisms to outcomes and complications. We compared men and women with known AF while treated with MRA to assess potential differences in stroke rate. Method: After IRB approval, we performed a retrospective chart review of all patients with confirmed HF and AF diagnoses. Patient data were extracted from electronic medical records. Patients with AF and HF treated with MRA were included in this study. Results: 64 patients with HF and AF treated with MRA were reviewed between January 2021 and September 2022. 34 were male, and 30 were female. Females were younger, 66 years (57 -74) compared to males, 73 years (60 - 78), p=.13. The median ejection fraction was similar among women, 42% (31 - 50) compared to men, 41% (33 - 49), p = .43. A significantly higher incidence of atrial fibrillation was found in our male group (59%) compared to the female group (30%), p=.02. There was no significant difference in MRA or anticoagulation use between male and female patients (p = .11, p = .12 respectively). More men had strokes compared to females (16% vs. 26% p = .17). Men were also more likely to be hypertensive compared to females (47% vs. 25%, p<.01). Conclusion: Men were more likely to have AF and stroke compared to females with HF on MRA therapy. Males were more likely to be hypertensive, which may relate to increased stroke rate in this patient population. Increased awareness of the gender-based prevalence of stroke rate in patients with HF and AF may allow for earlier recognition and reduction in stroke events.

ObjectiveTo develop evidence‐based consensus recommendations for the optimal timing of hip and knee arthroplasty to improve patient‐important outcomes including, but not limited to, pain, function, infection, hospitalization, and death at 1 year for patients with symptomatic and radiographic moderate‐to‐severe osteoarthritis or advanced symptomatic osteonecrosis with secondary arthritis of the hip or knee who have previously attempted nonoperative therapy, and for whom nonoperative therapy was ineffective, and who have chosen to undergo elective hip or knee arthroplasty (collectively referred to as TJA).MethodsWe developed 13 clinically relevant population, intervention, comparator, outcomes (PICO) questions. After a systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to rate the quality of evidence (high, moderate, low, or very low), and evidence tables were created. A Voting Panel, including 13 physicians and patients, discussed the PICO questions until consensus was achieved on the direction (for/against) and strength (strong/conditional) of the recommendations.ResultsThe panel conditionally recommended against delaying TJA to pursue additional nonoperative treatment including physical therapy, nonsteroidal antiinflammatory drugs, ambulatory aids, and intraarticular injections. It conditionally recommended delaying TJA for nicotine reduction or cessation. The panel conditionally recommended delay for better glycemic control for patients who have diabetes mellitus, although no specific measure or level was identified. There was consensus that obesity by itself was not a reason for delay, but that weight loss should be strongly encouraged, and the increase in operative risk should be discussed. The panel conditionally recommended against delay in patients who have severe deformity or bone loss, or in patients who have a neuropathic joint. Evidence for all recommendations was graded as low or very low quality.ConclusionThis guideline provides evidence‐based recommendations regarding the optimal timing of TJA in patients who have symptomatic and radiographic moderate‐to‐severe osteoarthritis or advanced symptomatic osteonecrosis with secondary arthritis for whom nonoperative therapy was ineffective to improve patient‐important outcomes, including pain, function, infection, hospitalization, and death at 1 year. We acknowledge that the evidence is of low quality primarily due to indirectness and hope future research will allow for further refinement of the recommendations.

AbstractLiver transplant patients require a multidisciplinary and personalized approach to optimize outcomes. Posttransplant complications can be devastating for the patient and can jeopardize graft survival. Therefore, a careful evaluation and stepwise decision-making process is necessary to determine the best strategy, whether it is surgical, interventional, or a combination of both. While access to liver transplant interventions in Latin America can be more limited compared with other parts of the world, many countries in the region have made significant progress in developing their liver transplant programs and improving the management of posttransplant complications. For example, in Brazil, specialized transplant centers and multidisciplinary teams have been established to reduce morbidity and improve graft survival rates. The article also explores the latest advancements in interventional radiology techniques, such as angioplasty, stent placement, and embolization, and how they can be used to successfully treat these complications. Overall, this article highlights the importance of a comprehensive approach to managing complications in liver transplant patients and emphasizes how individualized treatment plans can lead to improved outcomes, even in settings with limited resources.

Background: Left atrial (LA) myopathy with paroxysmal and permanent atrial fibrillation (AF) is frequent in chronic coronary syndromes (CCS) but sometimes occult at rest and elicited by stress. Aim: This study sought to assess LA volume and function at rest and during stress across the spectrum of AF. Methods: In a prospective, multicenter, observational study design, we enrolled 3042 patients [age = 64 ± 12; 63.8% male] with known or suspected CCS: 2749 were in sinus rhythm (SR, Group 1); 191 in SR with a history of paroxysmal AF (Group 2); and 102 were in permanent AF (Group 3). All patients underwent stress echocardiography (SE). We measured left atrial volume index (LAVI) in all patients and LA Strain reservoir phase (LASr) in a subset of 486 patients. Results: LAVI increased from Group 1 to 3, both at rest (Group 1 = 27.6 ± 12.2, Group 2 = 31.6 ± 12.9, Group 3 = 43.3 ± 19.7 mL/m2, p < 0.001) and at peak stress (Group 1 = 26.2 ± 12.0, Group 2 = 31.2 ± 12.2, Group 3 = 43.9 ± 19.4 mL/m2, p < 0.001). LASr progressively decreased from Group 1 to 3, both at rest (Group 1 = 26.0 ± 8.5%, Group 2 = 23.2 ± 11.2%, Group 3 = 8.5 ± 6.5%, p < 0.001) and at peak stress (Group 1 = 26.9 ± 10.1, Group 2 = 23.8 ± 11.0 Group 3 = 10.7 ± 8.1%, p < 0.001). Stress B-lines (≥2) were more frequent in AF (Group 1 = 29.7% vs. Group 2 = 35.5% vs. Group 3 = 57.4%, p < 0.001). Inducible ischemia was less frequent in SR (Group 1 = 16.1% vs. Group 2 = 24.7% vs. Group 3 = 24.5%, p = 0.001). Conclusions: In CCS, rest and stress LA dilation and reservoir dysfunction are often present in paroxysmal and, more so, in permanent AF and are associated with more frequent inducible ischemia and pulmonary congestion during stress.

Across multiancestry groups, we analyzed Human Leukocyte Antigen (HLA) associations in over 176,000 individuals with Parkinson’s disease (PD) and Alzheimer’s disease (AD) versus controls. We demonstrate that the two diseases share the same protective association at the HLA locus. HLA-specific fine-mapping showed that hierarchical protective effects of HLA-DRB1 *04 subtypes best accounted for the association, strongest with HLA-DRB1 *04:04 and HLA-DRB1 *04:07, and intermediary with HLA-DRB1 *04:01 and HLA-DRB1 *04:03. The same signal was associated with decreased neurofibrillary tangles in postmortem brains and was associated with reduced tau levels in cerebrospinal fluid and to a lower extent with increased Aβ42. Protective HLA-DRB1 *04 subtypes strongly bound the aggregation-prone tau PHF6 sequence, however only when acetylated at a lysine (K311), a common posttranslational modification central to tau aggregation. An HLA-DRB1 *04-mediated adaptive immune response decreases PD and AD risks, potentially by acting against tau, offering the possibility of therapeutic avenues.

Substance use disorders (SUDs) represent a current major public health concern in the United States and around the world. Social and economic stressors secondary to the coronavirus disease 2019 (COVID-19) pandemic have likely led to an increase in SUDs around the world. This chronic, debilitating disease is a prevalent health problem, and yet many clinicians do not have adequate training or clinical experience diagnosing and treating SUDs. Anesthesiologists and other perioperative medical staff frequently encounter patients with co-occurring SUDs. By such, through increased awareness and education, physicians and other health care providers have a unique opportunity to positively impact the lives and improve the perioperative outcomes of patients with SUDs. Understanding commonly used terms, potentially effective perioperative screening tools, diagnostic criteria, basics of treatment, and the perioperative implications of SUDs is essential to providing adequate care to patients experiencing this illness.
