Abstract
PURPOSE/OBJECTIVE(S) Anal cancer disproportionately affects PWH despite antiretroviral therapy. Data on CRT outcomes are limited. Modern IMRT CRT decreases acute toxicity but may exacerbate immune dysregulation from chronic HIV. Although historical CRT has been associated with prolonged CD4 count suppression, little is known about late immunotoxicity in PWH after contemporary CRT. We report clinical outcomes and long term immunotoxicity. MATERIALS/METHODS Single-center retrospective review of all PWH confirmed on chart review with anal squamous cell carcinoma without prior pelvic irradiation treated with definitive IMRT CRT. Patient and CRT factors including HIV suppression (<200 copies/mL), mean CD4 count (cells/µL), and receipt of capecitabine (C) or 5-fluorouracil (F) +/- mitomycin (M) were summarized with n (%) or median (interquartile range). Progression-free and overall survival (PFS; OS) were estimated per Kaplan-Meier with 95% confidence intervals and compared with log-rank tests. Mean CD4 count and CD4:CD8 were compared by HIV suppression status (Welch's t-test); longitudinal changes in median CD4 count and CD4:CD8 were compared between baseline vs. nadir (within 6 months of CRT start) and 1-year follow-up for patients with complete data (Wilcoxon signed-rank test). RESULTS A total of 23 PWH were treated between 2010-2022, median age 52, median 16 (13 - 19) years after HIV diagnosis; 4 had unsuppressed HIV; AJCC 8th stage I/II/III/IV 5/5/12/1. Radiation dose was median 54 Gy in 30 fractions over 42 (40 - 44) days. Most had C+M (57%); only 43% had 2×M with either C or F. One had neoadjuvant carboplatin/paclitaxel/pembrolizumab. With 2.9 (1.03 - 3.3) years follow-up, median OS was 6.6 (6.2 - unreached [UR]) years. With 2.2 (0.67 - 2.7) years follow-up, median PFS was UR. OS and PFS were similar regardless of HIV suppression status (both P ≥ 0.09). Overall baseline CD4 count was 458 (226 - 484), and CD4:CD8 was 0.54 (0.2 - 0.7). Nadir CD4 was 100 (59 - 126) and CD4:CD8 was 0.3 (0.2 - 0.4). Baseline and nadir CD4 count and CD4:CD8 were lower if HIV-unsuppressed (each P ≤ 0.04). One year after CRT, CD4 count was 252 (102 - 276), while CD4:CD8 was 0.5 (0.2 - 0.7). For 7 patients with repeated values the change in median from baseline to nadir, 6-, and 12-months post-CRT was -282, -549 (both P = 0.02), -480 (P = 0.9) for CD4 counts, and -0.7, -0.5, -0.4 (each P > 0.5) for CD4:CD8 ratios; none had unsuppressed HIV. CONCLUSION Definitive IMRT CRT with guideline-concordant doublet chemotherapy for anal cancer in PWH is effective despite unsuppressed HIV. Treatment leads to prolonged immunological changes that may increase the risk of HIV-related morbidity and mortality. Modifiable treatment-related causes of hematoimmunologic toxicity should be investigated further, and immune surveillance after CRT should be considered to better understand impact on quality of life.

Abstract
Abstract
Introduction/Objective
Myeloma diagnosis by a pathologist requires 10% plasma cells (PC) or a biopsy proven plasmacytoma in addition to myeloma defining events. PC% > 60% is a biomarker of malignancy under this definition. WHO allows for assesment of plasma cell percentage either by aspirate count or by CD138 immunohistochemistry (IHC). There is lack of consensus on aspirate smear adequacy for PC% estimation. Uneven distribution of plasma cells, hemodilution and/or patchy infiltration can lead to gross underestimation. We compared PC% by aspirate count and CD138 IHC and established corelation with serum protein electrophoresis (SPEP) values.
Methods
67 myeloma cases were included after excluding cases with suboptimal or inadequate aspirate smears. Two hematopathologists evaluated the diagnostic marrow (therapy naive) for PC% by aspirate count and CD138 IHC on biopsy/clot section. Corresponding SPEP and Free light chain (FLC) values were obtained. Correlation coefficent was calculated using Pearson correlation coefficient (GraphPad Prism).
Results
The Ig subtypes included IgG (41/67) and IgA (17/67). 12 cases had available FLC values. Both average and median PC% by CD138 IHC was considerably higher (50%, 52%) compared to aspirate count (29%, 21%). However, PC% by aspirate smear count and CD138 IHC demonstrated a significant linear correlation (r=0.71, p60% by CD138 (and not by aspirate count).
Conclusion
CD138 IHC based PC% is consistently higher, nevertheless, statistically significant linear corelation is observed between aspirate count PC% and CD138 IHC. A significant linear correlation is observed between CD138 IHC and SPEP (IgG and IgA), however, no such correlation is observed with aspirate count. More cases were diagnosed as myeloma (11%) and higher propotion of cases (35%) had biomarker of malignancy i.e. PC% >60% by CD138 IHC. Based on these findings, we propose estimation of PC% by CD138 immunostain be a recommended standard practice for better clinicopathologic and biologic correlation.

Abstract
BACKGROUND The utilization and extent of pelvic lymph node dissection (PLND) varies depending on the disease and practice patterns. AIMS This study compares practice patterns in utilization of PLND between Indian and United States (US) practices. SETTINGS AND DESIGN We focused on 415 patients (204 India; 211 US) prostate cancer patients treated with robot-assisted radical prostatectomy, between 2015 and 2016, within the Vattikuti Collective Quality Initiative database. SUBJECTS AND METHODS Utilization of PLND and number of nodes removed were evaluated for the entire cohort, and after stratifying for Country of treatment and D'Amico risk groups. Logistic regression tested the relationship between PLND and country of treatment, after adjusting for disease risk. RESULTS Indian patients had a higher risk distribution (D'Amico high-risk 53.4% in India vs. 27% in the US; P< 0.001) compared to their US counterparts. Overall, 193/204 (94.6%) Indian patients underwent PLND versus 181/211 (85.8%) US patients (P = 0.003). When stratified based on disease risk, PLND was performed more frequently in Indian patients with low-risk disease (81.0% vs. 41.4%,P= 0.008), but not in those with intermediate and high-risk disease. On multivariable analysis, Indian patients had a 2.57-fold higher probability of undergoing PLND than their US counterparts (P = 0.02). The analysis of the number of lymph nodes removed showed similar trends. CONCLUSIONS Indian patients are more likely to undergo PLND than US patients. This is, especially true for patients with low-risk disease, who are unlikely to benefit from this procedure. Efforts should focus on optimizing the utilization of PLND, and deliver it only when there is clinical indication.

Abstract
BACKGROUND A critical appraisal of the benefits of minimally invasive surgery (MIS) is needed, but is lacking. This study examined the associations between MIS and 30-day postoperative outcomes including complications graded according to the Clavien-Dindo classification, unplanned readmissions, hospital stay and mortality for five common surgical procedures. METHODS Patients undergoing appendicectomy, colectomy, inguinal hernia repair, hysterectomy and prostatectomy were identified in the American College of Surgeons National Surgical Quality Improvement Program database. Non-parsimonious propensity score methods were used to construct procedure-specific matched-pair cohorts that reduced baseline differences between patients who underwent MIS and those who did not. Bonferroni correction for multiple comparisons was applied and P < 0·006 was considered significant. RESULTS Of the 532 287 patients identified, 53·8 per cent underwent MIS. Propensity score matching yielded an overall sample of 327 736 patients (appendicectomy 46 688, colectomy 152 114, inguinal hernia repair 59 066, hysterectomy 59 066, prostatectomy 10 802). Within the procedure-specific matched pairs, MIS was associated with significantly lower odds of Clavien-Dindo grade I-II, III and IV complications (P ≤ 0·004), unplanned readmissions (P < 0·001) and reduced hospital stay (P < 0·001) in four of the five procedures studied, with the exception of inguinal hernia repair. The odds of death were lower in patients undergoing MIS colectomy (P < 0·001), hysterectomy (P = 0·002) and appendicectomy (P = 0·002). CONCLUSION MIS was associated with significantly fewer 30-day postoperative complications, unplanned readmissions and deaths, as well as shorter hospital stay, in patients undergoing colectomy, prostatectomy, hysterectomy or appendicectomy. No benefits were noted for inguinal hernia repair.

Abstract
BACKGROUND Renal squamous cell carcinoma is a rare primary tumor of the kidney that rapidly invades local structures and has a poor prognosis. Presentation is usually nonspecific and is associated with renal stone disease and chronic infection. Immunosuppressed renal transplant recipients are more likely to develop a malignancy than the general population. Squamous cell carcinoma of the kidney in the context of a renal transplant and long-term immunosuppression has not previously been described in the literature. CASE REPORT A 46-year-old white man with previous renal stones and recurrent urinary infections underwent a right nephrectomy and subsequent renal transplantation owing to failure of the remaining kidney. Five years posttransplant, an abdominal ultrasound scan was performed owing to recurrent urinary infections and ongoing pyuria. This was reported as normal, but he later developed a discharging sinus in his left flank. A computed tomography (CT) scan revealed a tracking perinephric abscess with an associated cystic lesion of the left kidney. A left nephrectomy was performed and histologic examination suggested an invasive squamous cell carcinoma of the renal pelvis. The patient later required major surgery for chronic infection, and further imaging revealed metastatic disease, resulting in the decision to manage palliatively. CONCLUSION Given the nonspecific nature of the symptoms and the poor prognosis, health care professionals should have a lower threshold for diagnostic imaging in these patients. Abdominal ultrasonography was unhelpful and only a later CT scan revealed the underlying malignancy. This should be expedited if there is a persistent abnormality on urinalysis. Once diagnosed, a change in immunosuppressant regime to include sirolimus should be considered.

Abstract
PURPOSE Stable fixation of distal humerus fracture fragments is necessary for adequate healing and maintenance of reduction. The purpose of this study was to measure the reliability and accuracy of interpretation of postoperative radiographs to predict which implants will loosen or break after operative treatment of bicolumnar distal humerus fractures. We also addressed agreement among surgeons regarding which fracture fixation will loosen or break and the influence of years in independent practice, location of practice, and so forth. METHODS A total of 232 orthopedic residents and surgeons from around the world evaluated 24 anteroposterior and lateral radiographs of distal humerus fractures on a Web-based platform to predict which implants would loosen or break. Agreement among observers was measured using the multi-rater kappa measure. RESULTS The sensitivity of prediction of failure of fixation of distal humerus fracture on radiographs was 63%, specificity was 53%, positive predictive value was 36%, the negative predictive value was 78%, and accuracy was 56%. There was fair interobserver agreement (κ = 0.27) regarding predictions of failure of fixation of distal humerus fracture on radiographs. Interobserver variability did not change when assessed for the various subgroups. CONCLUSIONS When experienced and skilled surgeons perform fixation of type C distal humerus fracture, the immediate postoperative radiograph is not predictive of fixation failure. Reoperation based on the probability of failure might not be advisable. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic III.

Abstract
Gap engineering of ZnO by codoping it with III-V materials is investigated using model and ab initio calculation. Our results show that the codoped materials (ZnO)1-x (III-V)x , where (III-V) stands for GaN, AlN, AlP, BN, BP exhibit energy band gaps that get smaller as the dopant concentrations x is increased. Even at a very small dopant concentration the obtained band gaps are found to be much smaller than that of ZnO making the studied (ZnO)1-x(III-V)x materials promising candidates for photoelectrochemical water splitting.

Abstract
PURPOSE To examine the potential relationship between androgen deprivation therapy and other-cause mortality (OCM) in patients with prostate cancer treated with medical primary-androgen deprivation therapy, prostatectomy, or radiation. METHODS A total of 137,524 patients with non-metastatic PCa treated between 1995 and 2009 within the Surveillance Epidemiology and End Results Medicare-linked database were included. Cox-regression analysis tested the association of ADT with OCM. A 40-item comorbidity score was used for adjustment. RESULTS Overall, 9.3% of patients harbored stage III-IV disease, and 57.7% of patients received ADT. The mean duration of ADT exposure was 22.9 months (median: 9.1; IQR: 2.8-31.5). Mean and median follow-up were 66.9, and 60.4 months, respectively. At 10 years, overall-OCM rate was 36.5%; it was 30.6% in patients treated without ADT vs. 40.1% in patients treated with ADT (p < 0.001). In multivariable-analysis, ADT was associated with an increased risk of OCM (Hazard-ratio [HR]: 1.11, 95% Confidence-interval [95% CI]: 1.08-1.13). Patients with no comorbidity (10-year OCM excess risk: 9%) were more subject to harm from ADT than patients with high comorbidity (10-year OCM excess risk: 4.7%). CONCLUSIONS In patients with PCa, treatment with medical ADT may increase the risk of mortality due to causes other than PCa. Whether this is a simple association or a cause-effect relationship is unknown and warrants further study in prospective studies.

Abstract
This review focuses primarily on the complexities of chronotoxicity and chronopharmacology (time-of-day effects on the metabolism of environmental chemicals and therapeutic agents as related to chronobiology). The nature of the melatonin signal may modify the function of the hepatic endoplasmic reticulum resulting in variations in the metabolism of xenobiotic chemicals. Concepts are explored for modification of exposure limits and/or Threshold Limit Values (TLVs) of industrial chemicals in risk assessment and health effects of workers on rotating shifts. The TLVs of chemicals may be changed during work shift schedules to minimize adverse health effects among workers.

Abstract
INTRODUCTION We receive fast track referrals on the basis of iron deficiency anaemia (IDA) for patients with normocytic anaemia or for patients with no iron studies. This study examined the yield of colorectal cancer (CRC) among fast track patients to ascertain whether awaiting confirmation of IDA is necessary prior to performing bowel investigations. METHODS A review was undertaken of 321 and 930 consecutive fast track referrals from Centre A and Centre B respectively. Contingency tables were analysed using Fisher's exact test. Logistic regression analyses were performed to investigate significant predictors of CRC. RESULTS Overall, 229 patients were included from Centre A and 689 from Centre B. The odds ratio for microcytic anaemia versus normocytic anaemia in the outcome of CRC was 1.3 (95% confidence interval [CI]: 0.5-3.9) for Centre A and 1.6 (95% CI: 0.8-3.3) for Centre B. In a logistic regression analysis (Centre B only), no significant difference in CRC rates was seen between microcytic and normocytic anaemia (adjusted odds ratio: 1.9, 95% CI: 0.9-3.9). There was no statistically significant difference in the yield of CRC between microcytic and normocytic anaemia (p=0.515, Fisher's exact test) in patients with anaemia only and no colorectal symptoms. Finally, CRC cases were seen in both microcytic and normocytic groups with or without low ferritin. CONCLUSIONS There is no significant difference in the yield of CRC between fast track patients with microcytic and normocytic anaemia. This study provides insufficient evidence to support awaiting confirmation of IDA in fast track patients with normocytic anaemia prior to requesting bowel investigations.

Abstract
Androgen Receptor (AR) signaling is critically important during the development and progression of prostate cancer (PCa). The AR signaling is also important in the development of castrate resistant prostate cancer (CRPC) where AR is functional even after androgen deprivation therapy (ADT); however, little is known regarding the transcriptional and functional regulation of AR in PCa. Moreover, treatment options for primary PCa for preventing the occurrence of CRPC is limited; therefore, novel strategy for direct inactivation of AR is urgently needed. In this study, we found loss of miR-34a, which targets AR, in PCa tissue specimens, especially in patients with higher Gleason grade tumors, consistent with increased expression of AR. Forced over-expression of miR-34a in PCa cell lines led to decreased expression of AR and prostate specific antigen (PSA) as well as the expression of Notch-1, another important target of miR-34a. Most importantly, BR-DIM intervention in PCa patients prior to radical prostatectomy showed reexpression of miR-34a, which was consistent with decreased expression of AR, PSA and Notch-1 in PCa tissue specimens. Moreover, BR-DIM intervention led to nuclear exclusion both in PCa cell lines and in tumor tissues. PCa cells treated with BR-DIM and 5-aza-dC resulted in the demethylation of miR-34a promoter concomitant with inhibition of AR and PSA expression in LNCaP and C4-2B cells. These results suggest, for the first time, epigenetic silencing of miR-34a in PCa, which could be reversed by BR-DIM treatment and, thus BR-DIM could be useful for the inactivation of AR in the treatment of PCa.[This corrects the article on p. 14 in vol. 4.].

Abstract
BACKGROUND We assessed the distribution of site-specific metastases in patients with renal cell carcinoma (RCC) according to age. Moreover, we evaluated recommendations proposed by guidelines and focused specifically on bone and brain metastases. PATIENTS AND METHODS Patients with metastatic RCC (mRCC) were abstracted from the Nationwide Inpatient Sample (1998-2007). Age was stratified into four groups: <55, 55-64, 65-74 and ≥ 75 years. Cochran-Armitage trend test and multivariable logistic regression analysis tested the relationship between age and the rate of multiple metastatic sites. Finally, we examined the rates of brain or bone metastases according to the presence of other metastatic sites. RESULTS In 11,157 mRCC patients, the rate of multiple metastatic sites decreased with increasing age (P < 0.001). This phenomenon was confirmed in patients with lung, bone, liver and brain metastases (all P ≤ 0.01). The rate of bone metastases was 10% in patients with exclusive abdominal metastases and 49% in patients with abdominal, thoracic and brain metastases. The rate of brain metastases was 2% in patients with exclusive abdominal metastases and 16% in patients with thoracic and bone metastases. CONCLUSIONS The proportion of patients with multiple metastatic sites is higher in young patients. The rates of bone (10%-49%) and brain (2%-16%) metastases are nonnegligible in mRCC patients.

Abstract
In Indonesia, where diarrhea remains a major cause of mortality among children <5 years, the government promotes boiling of drinking water. We assessed the impact of boiling on water quality in South Sulawesi. We surveyed randomly selected households with at least one child <5 years old in two rural districts and tested source and stored water samples for Escherichia coli contamination. Among 242 households, 96% of source and 51% of stored water samples yielded E. coli. Unboiled water samples, obtained from 15% of households, were more likely to yield E. coli than boiled samples [prevalence ratios (PR) = 2.0, 95% confidence interval (CI) 1.7-2.5]. Water stored in wide-mouthed (PR = 1.4, 95% CI = 1.1-1.8) or uncovered (PR = 1.8, 95% CI = 1.3-2.4) containers, or observed to be touched by the respondent's hands (PR = 1.6, 95% CI = 1.3-2.1) was more likely to yield E. coli. A multivariable model showed that households that did not boil water were more likely to have contaminated stored water than households that did boil water (PR = 1.9, 95% CI = 1.5-2.3). Although this study demonstrated the effectiveness of boiling in reducing contamination, overall impact on water quality was suboptimal. Future studies are needed to identify factors behind the success of boiling water in Indonesia to inform efforts to scale up other effective water treatment practices.
