ABSTRACT
PURPOSE: Incisional hernias are a frequent complication following robotic radical prostatectomy. Observational data in men undergoing robotic prostatectomy suggest that transverse closure resulted in lower hernia rates than vertical closure. We sought to compare the incidence of incisional hernia after robotic radical prostatectomy after vertical and transverse extraction site closure. MATERIALS AND METHODS: We conducted a clinically integrated, crossover, cluster randomized trial at a single tertiary referral center (January 2016-September 2021) comparing the rate of hernia after transverse vs vertical extraction site excision in 1356 patients treated with minimally invasive radical prostatectomy. The primary outcome was between-group incidence of incisional hernia within 15 months of prostatectomy defined by physical examination and self-reported patient surveys. RESULTS: Overall, 197 (20%) patients developed an incisional hernia within 15 months, 797 did not have an incisional hernia within this period, and 362 had missing outcome data regarding incisional hernia. We found no significant difference in hernia rates between the 2 incision types (absolute between-group difference 1.8%; 95% CI -3.4%, 6.6%; P = .5) in the primary analysis or in the 3 sensitivity analyses. Notably, because of the inclusive definition of hernia used, these data cannot be used as an estimate of the true prevalence of incisional hernia. CONCLUSIONS: Surgeons should choose the incision and closure approach they are most comfortable with when extracting specimens. Studies of modifications to the surgical technique are best conducted as randomized comparisons, and the clinically integrated, crossover, cluster randomized trial allows large trials to be completed at a single center and at low cost. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01407263.

PURPOSE: To determine whether objective measures of oral health and salivary gland irradiation correlates with subjective measures of eating, drinking, and salivation in patients following head and neck radiation therapy (HNRT). METHODS: This cross-sectional study included 112 patients following HNRT with a completed patient-reported outcome (PRO) scale. Objective measures at post-HNRT visit included decayed-missing-filled teeth (DMFT) scores, periodontal disease condition, oral hygiene status, dental prosthesis use, and prescribed radiation dose to salivary glands. Data were collected and statistical analysis was performed. RESULTS: There was no significant association between PRO scales and dental prosthesis use, periodontal disease, and oral hygiene. Although some significant findings were seen with DMFT and prescribed radiation dose to salivary glands, this explained only very small amounts of the variation in eating, drinking, and salivation measures in these patients. CONCLUSION: PRO measures should be integrated in the routine care of patients with head and neck cancer.
ABSTRACT
BACKGROUND: Performing large randomized trials in anesthesiology is often challenging and costly. The clinically integrated randomized trial is characterized by simplified logistics embedded into routine clinical practice, enabling ease and efficiency of recruitment, offering an opportunity for clinicians to conduct large, high-quality randomized trials under low cost. Our aims were to (1) demonstrate the feasibility of the clinically integrated trial design in a high-volume anesthesiology practice and (2) assess whether trial quality improvement interventions led to more balanced accrual among study arms and improved trial compliance over time. METHODS: This is an interim analysis of recruitment to a cluster-randomized trial investigating three nerve block approaches for mastectomy with immediate implant-based reconstruction: paravertebral block (arm 1), paravertebral plus interpectoral plane blocks (arm 2), and serratus anterior plane plus interpectoral plane blocks (arm 3). We monitored accrual and consent rates, clinician compliance with the randomized treatment, and availability of outcome data. Assessment after the initial year of implementation showed a slight imbalance in study arms suggesting areas for improvement in trial compliance. Specific improvement interventions included increasing the frequency of communication with the consenting staff and providing direct feedback to clinician investigators about their individual recruitment patterns. We assessed overall accrual rates and tested for differences in accrual, consent, and compliance rates pre- and post-improvement interventions. RESULTS: Overall recruitment was extremely high, accruing close to 90% of the eligible population. In the pre-intervention period, there was evidence of bias in the proportion of patients being accrued and receiving the monthly block, with higher rates in arm 3 (90%) compared to arms 1 (81%) and 2 (79%, p = 0.021). In contrast, in the post-intervention period, there was no statistically significant difference between groups (p = 0.8). Eligible for randomization rate increased from 89% in the pre-intervention period to 95% in the post-intervention period (difference 5.7%; 95% confidence interval = 2.2%-9.4%, p = 0.002). Consent rate increased from 95% to 98% (difference of 3.7%; 95% confidence interval = 1.1%-6.3%; p = 0.004). Compliance with the randomized nerve block approach was maintained at close to 100% and availability of primary outcome data was 100%. CONCLUSION: The clinically integrated randomized trial design enables rapid trial accrual with a high participant compliance rate in a high-volume anesthesiology practice. Continuous monitoring of accrual, consent, and compliance rates is necessary to maintain and improve trial conduct and reduce potential biases. This trial methodology serves as a template for the implementation of other large, low-cost randomized trials in anesthesiology.
ABSTRACT
INTRODUCTION: Gabapentin has been used in enhanced recovery after surgery (ERAS) pathways for pain control for patients undergoing ambulatory uro-oncologic surgery; however, it may cause undesirable side effects. We studied the causal association between gabapentin and rapidity of recovery and perioperative pain management after minimally invasive uro-oncologic surgery. METHODS: We identified 2397 patients ≤ 65 years undergoing prostatectomies or nephrectomies between 2018 and 2022; 131 (5.5%) did not receive gabapentin. We tested the effect of gabapentin use on time of discharge and perioperative opioid consumption, respectively, using multivariable linear regression adjusting for potential confounders including age, gender, BMI, American Society of Anesthesiologists score, and surgery type. RESULTS: On adjusted analysis, we found no evidence of a difference in discharge time among those who did vs did not receive gabapentin (adjusted difference 0.07 hours shorter on gabapentin; 95% CI -0.17, 0.31; P = .6). There was no evidence of a difference in intraoperative opioid consumption by gabapentin receipt (adjusted difference -1.5 morphine milligram equivalents; 95% CI -4.2, 1.1; P = .3) or probability of being in the top quartile of postoperative opioid consumption within 24 hours (adjusted difference 4.2%; 95% CI -4.8%, 13%; P = .4). We saw no important differences in confounders by gabapentin receipt suggesting causal conclusions are justified. CONCLUSIONS: Our confidence intervals did not include clinically meaningful benefits from gabapentin, when used with an ERAS protocol, in terms of length of stay or perioperative opioid use. These results support the omission of gabapentin from ERAS protocols for minimally invasive uro-oncologic surgeries.

OBJECTIVES: While clinical practice guidelines recommend that oncologists discuss goals of care with patients who have advanced cancer, it is estimated that less than 20% of individuals admitted to the hospital with high-risk cancers have end-of-life discussions with their providers. While there has been interest in developing models for mortality prediction to trigger such discussions, few studies have compared how such models compare with clinical judgment to determine a patient's mortality risk. METHODS: This study is a prospective analysis of 1,069 solid tumor medical oncology hospital admissions (n = 911 unique patients) from February 7 to June 7, 2022, at Memorial Sloan Kettering Cancer Center. Electronic surveys were sent to hospitalists, advanced practice providers, and medical oncologists the first afternoon following a hospital admission and they were asked to estimate the probability that the patient would die within 45 days. Provider estimates of mortality were compared with those from a predictive model developed using a supervised machine learning methodology, and incorporated routine laboratory, demographic, biometric, and admission data. Area under the receiver operating characteristic curve (AUC), calibration and decision curves were compared between clinician estimates and the model predictions. RESULTS: Within 45 days following hospital admission, 229 (25%) of 911 patients died. The model performed better than the clinician estimates (AUC 0.834 vs. 0.753, p < 0.0001). Integrating clinician predictions with the model's estimates further increased the AUC to 0.853 (p < 0.0001). Clinicians overestimated risk whereas the model was extremely well-calibrated. The model demonstrated net benefit over a wide range of threshold probabilities. CONCLUSION: The inpatient prognosis at admission model is a robust tool to assist clinical providers in evaluating mortality risk, and it has recently been implemented in the electronic medical record at our institution to improve end-of-life care planning for hospitalized cancer patients.

BACKGROUND: Bacterial diversity could contribute to the diversity of tuberculosis infection and treatment outcomes observed clinically, but the biological basis of this association is poorly understood. The aim of this study was to identify associations between phenogenomic variation in Mycobacterium tuberculosis and tuberculosis clinical features. METHODS: We developed a high-throughput platform to define phenotype-genotype relationships in M tuberculosis clinical isolates, which we tested on a set of 158 drug-sensitive M tuberculosis strains sampled from a large tuberculosis clinical study in Ho Chi Minh City, Viet Nam. We tagged the strains with unique genetic barcodes in multiplicate, allowing us to pool the strains for in-vitro competitive fitness assays across 16 host-relevant antibiotic and metabolic conditions. Relative fitness was quantified by deep sequencing, enumerating output barcode read counts relative to input normalised values. We performed a genome-wide association study to identify phylogenetically linked and monogenic mutations associated with the in-vitro fitness phenotypes. These genetic determinants were further associated with relevant clinical outcomes (cavitary disease and treatment failure) by calculating odds ratios (ORs) with binomial logistic regressions. We also assessed the population-level transmission of strains associated with cavitary disease and treatment failure using terminal branch length analysis of the phylogenetic data. FINDINGS: M tuberculosis clinical strains had diverse growth characteristics in host-like metabolic and drug conditions. These fitness phenotypes were highly heritable, and we identified monogenic and phylogenetically linked variants associated with the fitness phenotypes. These data enabled us to define two genetic features that were associated with clinical outcomes. First, mutations in Rv1339, a phosphodiesterase, which were associated with slow growth in glycerol, were further associated with treatment failure (OR 5·34, 95% CI 1·21-23·58, p=0·027). Second, we identified a phenotypically distinct slow-growing subclade of lineage 1 strains (L1.1.1.1) that was associated with cavitary disease (OR 2·49, 1·11-5·59, p=0·027) and treatment failure (OR 4·76, 1·53-14·78, p=0·0069), and which had shorter terminal branch lengths on the phylogenetic tree, suggesting increased transmission. INTERPRETATION: Slow growth under various antibiotic and metabolic conditions served as in-vitro intermediate phenotypes underlying the association between M tuberculosis monogenic and phylogenetically linked mutations and outcomes such as cavitary disease, treatment failure, and transmission potential. These data suggest that M tuberculosis growth regulation is an adaptive advantage for bacterial success in human populations, at least in some circumstances. These data further suggest markers for the underlying bacterial processes that contribute to these clinical outcomes.

Tuberculosis (TB) is a major cause of morbidity and mortality worldwide despite widespread intradermal (ID) BCG vaccination in newborns. We previously demonstrated that changing the route and dose of BCG vaccination from 5×105 CFU ID to 5×107 CFU intravenous (IV) resulted in prevention of infection and disease in a rigorous, highly susceptible non-human primate model of TB. Identifying the immune mechanisms of protection for IV BCG will facilitate development of more effective vaccines against TB. Here, we depleted select lymphocyte subsets in IV BCG vaccinated macaques prior to Mtb challenge to determine the cell types necessary for that protection. Depletion of CD4 T cells or all CD8α expressing lymphoycytes (both innate and adaptive) resulted in loss of protection in most macaques, concomitant with increased bacterial burdens (~4-5 log10 thoracic CFU) and dissemination of infection. In contrast, depletion of only adaptive CD8αß+ T cells did not significantly reduce protection against disease. Our results demonstrate that CD4 T cells and innate CD8α+ lymphocytes are critical for IV BCG-induced protection, supporting investigation of how eliciting these cells and their functions can improve future TB vaccines.

BACKGROUND AND OBJECTIVES: Expanding outpatient surgery to the increasing number of procedures and patient populations warrants continuous evaluation of postoperative outcomes to ensure the best care and safety. We describe adverse postoperative outcomes and transfer rates related to anesthesia in a large sample of patients who underwent same-day cancer surgery at a freestanding ambulatory surgery center. METHODS: Between January 2017 and June 2021, 3361 cancer surgeries, including breast and plastic, head and neck, gynecology, and urology, were performed. The surgeries were indicated for diagnosis, staging, and/or treatment. We report the incidence of transfers and adverse postoperative outcomes related to anesthesia. RESULTS: Breast and plastic surgeries were the most common (1771, 53%), followed by urology (1052, 31%), gynecology (410, 12%), and head and neck surgeries (128, 4%). Based on patients' first procedure, comorbidity levels were highest for urology (75% American Society of Anesthesiologists physical status score 3, 1.7% score 4) and lowest for breast surgeries (31% score 3, 0.2% score 4). Most gynecology surgeries used general anesthesia (97.6%), whereas breast surgeries used the least (38%). A total of seven patients (0.2%; 95% CI: 0.08%-0.4%) were immediately transferred to an outside hospital; four due to anesthesia-related reasons. Only 7 (0.2%) patients needed additional postoperative care related to anesthesia-related adverse events, specifically cardiac events (4), difficult intubations (2), desaturation (1), and agitation, nausea, and headache (1). CONCLUSIONS: The incidence of anesthesia-related adverse postoperative outcomes is low in cancer patients undergoing outpatient surgeries at our freestanding ambulatory surgery center. This suggests that carefully selected cancer patients, including patients with metastatic cancer, can undergo anesthesia for same-day surgery, making cancer care accessible locally and reducing stress associated with travel for treatment. More research investigating complication rates related to surgery and to cancer disease trajectory are needed to establish a complete evaluation of safety for outpatient cancer surgery.

Importance: Complex cancer procedures are now performed in the ambulatory surgery setting. Remote symptom monitoring (RSM) with electronic patient-reported outcomes (ePROs) can identify patients at risk for acute hospital encounters. Defining normal recovery is needed to set patient expectations and optimize clinical team responses to manage evolving problems in real time. Objective: To describe the patterns of postoperative recovery among patients undergoing ambulatory cancer surgery with RSM using an ePRO platform-the Recovery Tracker. Design, Setting, and Participants: In this retrospective cohort study, patients who underwent 1 of 5 of the most common procedures (prostatectomy, nephrectomy, mastectomy, hysterectomy, or thyroidectomy) at the Josie Robertson Surgery Center at Memorial Sloan Kettering Cancer Center from September 2016 to June 2022. Patients completed the Recovery Tracker, a brief ePRO platform assessing symptoms for 10 days after surgery. Data were analyzed from September 2022 to May 2023. Main Outcomes and Measures: Symptom severity and interference were estimated by postoperative day and procedure. Results: A total of 12â¯433 patients were assigned 110â¯936 surveys. Of these patients, 7874 (63%) were female, and the median (IQR) age at surgery was 57 (47-65) years. The survey response rate was 87% (10â¯814 patients responding to at least 1 of 10 daily surveys). Among patients who submitted at least 1 survey, the median (IQR) number of surveys submitted was 7 (4-8), and each assessment took a median (IQR) of 1.7 (1.2-2.5) minutes to complete. Symptom burden was modest in this population, with the highest severity on postoperative days 1 to 3. Pain was moderate initially and steadily improved. Fatigue was reported by 6120 patients (57%) but was rarely severe. Maximum pain and fatigue responses (very severe) were reported by 324 of 10â¯814 patients (3%) and 106 of 10â¯814 patients (1%), respectively. The maximum pain severity (severe or very severe) was highest after nephrectomy (92 of 332 [28%]), followed by mastectomy with reconstruction (817 of 3322 [25%]) and prostatectomy (744 of 3543 [21%]). Nausea (occasionally, frequently, or almost constantly) was common and experienced on multiple days by 1485 of 9300 patients (16%), but vomiting was less common (139 of 10â¯812 [1%]). Temperature higher than 38 °C was reported by 740 of 10â¯812 (7%). Severe or very severe shortness of breath was reported by 125 of 10â¯813 (1%). Conclusions and Relevance: Defining detailed postoperative symptom burden through this analysis provides valuable data to inform further implementation and maintenance of RSM programs in surgical oncology patients. These data can enhance patient education, set expectations, and support research to allow iterative improvement of clinical care based on the patient-reported experience after discharge.

BACKGROUND: Electronic patient-reported outcome measures (ePROMs) for real-time remote symptom monitoring facilitate early recognition of postoperative complications. We sought to determine whether remote, electronic, patient-reported symptom-monitoring with Recovery Tracker predicts 30-day readmission or reoperation in outpatient mastectomy patients. METHODS: We conducted a retrospective review of breast cancer patients who underwent outpatient (< 24-h stay) mastectomy with or without reconstruction from April 2017 to January 2022 and who received the Recovery Tracker on Days 1-10 postoperatively. Of 5,130 patients, 3,888 met the inclusion criteria (2,880 mastectomy with immediate reconstruction and 1,008 mastectomy only). We focused on symptoms concerning for surgical complications and assessed if symptoms reaching prespecified alert levels-prompting a nursing call-predicted risk of 30-day readmission or reoperation. RESULTS: Daily Recovery Tracker response rates ranged from 45% to 70%. Overall, 1,461 of 3,888 patients (38%) triggered at least one alert. Most red (urgent) alerts were triggered by pain and fever; most yellow (less urgent) alerts were triggered by wound redness and pain severity. The 30-day readmission and reoperation rates were low at 3.8% and 2.4%, respectively. There was no statistically significant association between symptom alerts and 30-day reoperation or readmission, and a clinically relevant increase in risk can be excluded (odds ratio 1.08; 95% confidence interval 0.8-1.46; p = 0.6). CONCLUSIONS: Breast cancer patients undergoing mastectomy with or without reconstruction in the ambulatory setting have a low burden of concerning symptoms, even in the first few days after surgery. Patients can be reassured that symptoms that do present resolve quickly thereafter.

The bacterial determinants that facilitate Mycobacterium tuberculosis (Mtb) adaptation to the human host environment are poorly characterized. We have sought to decipher the pressures facing the bacterium in vivo by assessing Mtb genes that are under positive selection in clinical isolates. One of the strongest targets of selection in the Mtb genome is lldD2, which encodes a quinone-dependent L-lactate dehydrogenase (LldD2) that catalyzes the oxidation of lactate to pyruvate. Lactate accumulation is a salient feature of the intracellular environment during infection and lldD2 is essential for Mtb growth in macrophages. We determined the extent of lldD2 variation across a set of global clinical isolates and defined how prevalent mutations modulate Mtb fitness. We show the stepwise nature of lldD2 evolution that occurs as a result of ongoing lldD2 selection in the background of ancestral lineage-defining mutations and demonstrate that the genetic evolution of lldD2 additively augments Mtb growth in lactate. Using quinone-dependent antibiotic susceptibility as a functional reporter, we also find that the evolved lldD2 mutations functionally increase the quinone-dependent activity of LldD2. Using 13C-lactate metabolic flux tracing, we find that lldD2 is necessary for robust incorporation of lactate into central carbon metabolism. In the absence of lldD2, label preferentially accumulates in dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-phosphate (G3P) and is associated with a discernible growth defect, providing experimental evidence for accrued lactate toxicity via the deleterious buildup of sugar phosphates. The evolved lldD2 variants increase lactate incorporation to pyruvate while altering triose phosphate flux, suggesting both an anaplerotic and detoxification benefit to lldD2 evolution. We further show that the mycobacterial cell is transcriptionally sensitive to the changes associated with altered lldD2 activity which affect the expression of genes involved in cell wall lipid metabolism and the ESX- 1 virulence system. Together, these data illustrate a multifunctional role of LldD2 that provides context for the selective advantage of lldD2 mutations in adapting to host stress.

BACKGROUND AND OBJECTIVE: The transrectal biopsy approach is traditionally used to detect prostate cancer. An alternative transperineal approach is historically performed under general anesthesia, but recent advances enable transperineal biopsy to be performed under local anesthesia. We sought to compare infectious complications of transperineal biopsy without antibiotic prophylaxis versus transrectal biopsy with targeted prophylaxis. METHODS: We assigned biopsy-naïve participants to undergo transperineal biopsy without antibiotic prophylaxis versus transrectal biopsy with targeted prophylaxis (rectal culture screening for fluoroquinolone-resistant bacteria and antibiotic targeting to culture and sensitivity results) through a multicenter, randomized trial. The primary outcome was post-biopsy infection captured by a prospective medical review and patient report on a 7-d survey. The secondary outcomes included cancer detection, noninfectious complications, and a numerical rating scale (0-10) for biopsy-related pain and discomfort during and 7-d after biopsy. KEY FINDINGS AND LIMITATIONS: A total of 658 participants were randomized, with zero transperineal versus four (1.4%) transrectal biopsy infections (difference -1.4%; 95% confidence interval [CI] -3.2%, 0.3%; p = 0.059). The rates of other complications were very low and similar. Importantly, detection of clinically significant cancer was similar (53% transperineal vs 50% transrectal, adjusted difference 2.0%; 95% CI -6.0, 10). Participants in the transperineal arm experienced worse periprocedural pain (0.6 adjusted difference [0-10 scale], 95% CI 0.2, 0.9), but the effect was small and resolved by 7-d. CONCLUSIONS AND CLINICAL IMPLICATIONS: Office-based transperineal biopsy is tolerable, does not compromise cancer detection, and did not result in infectious complications. Transrectal biopsy with targeted prophylaxis achieved similar infection rates, but requires rectal cultures and careful attention to antibiotic selection and administration. Consideration of these factors and antibiotic stewardship should guide clinical decision-making. PATIENT SUMMARY: In this multicenter randomized trial, we compare prostate biopsy infectious complications for the transperineal versus transrectal approach. The absence of infectious complications with transperineal biopsy without the use of preventative antibiotics is noteworthy, but not significantly different from transrectal biopsy with targeted antibiotic prophylaxis.
