Abstract
OBJECTIVE To explore changing trends and characteristics in neuroendocrine tumors (NETs) epidemiology, focusing on demographics, clinical aspects, and survival, including the impact of social determinants of health (SDOH) on outcomes. BACKGROUND The escalating incidence and prevalence of NETs underscore the pressing need for updated epidemiologic data to reveal the evolving landscape of this condition. Access to current information is imperative for informing clinical strategies and public health initiatives targeting NETs. METHODS A retrospective, population-based study analyzed NET patient data from 1975 to 2020, using the Surveillance, Epidemiology, and End Results (SEER 8, 12, 18) program. We calculated annual age-adjusted incidence, prevalence, and 5-year overall survival (OS) rates. Survival trends from 2000 to 2019 were examined, employing the Fine-Gray model to evaluate cancer-specific mortality. RESULTS NETs' age-adjusted incidence rate quadrupled from 1.5 per 100,000 in 1975 to 6.0 per 100,000 in 2020. A decline in incidence occurred from 6.8 per 100,000 in 2019 to 6.0 per 100,000 in 2020. All-cause survival multivariable analysis demonstrated high grade (HR: 2.95, 95% CI: 2.63-3.09, P<0.001), single patients (HR: 1.49, 95% CI: 1.45-1.54, P<0.001), and Black patients (HR: 1.17, 95% CI:1.13-1.22, P<0.001) all had worse survival than their controls. CONCLUSION In conclusion, our study shows a steady increase in NETs incidence until 2019, with a decline in 2020. Understanding the reasons behind this trend is vital for improved management and public health planning. Further research should focus on the factors driving these changes to enhance our understanding of NET epidemiology.

Abstract
OBJECTIVES The purpose of this study was to explore adherence to the American Cancer Society (ACS) Head and Neck Cancer (HNC) Survivorship Care Guideline and their outlined 33 recommendations among posttreatment HNC survivors. METHODS A bi-institutional, retrospective, nested cohort study of mucosal or salivary gland HNC survivors diagnosed in 2018 was designed. Guideline adherence was assessed via retrospective chart review between 0 and 13 months after completion of oncologic treatment according to 4 categories: (1) problem assessed, (2) problem diagnosed, (3) management offered; (4) problem treated. Adherence was defined as meeting a recommendation subcategory at least once over the 13-month period. RESULTS Among 60 randomly selected HNC survivors, a total of 38 were included in the final cohort after exclusion of individuals with ineligible cancers and those who died or were lost to follow-up over the study period. Approximately 95% of HNC survivors were assessed for HNC recurrence and screened for lung cancer. Certain common problems such as xerostomia, dysphagia, and hypothyroidism were screened for and managed in ≥70% of eligible survivors. Conversely, screening for other second primary cancers and assessment of a majority of other physical and psychosocial harms occurred in <70% of survivors, and in many cases none to a slim minority of survivors (eg, sleep apnea and sleep disturbance, body and self-image concerns). Only 5% of survivors received a survivorship care plan. CONCLUSION Overall adherence to the ACS HNC Survivorship Care Guideline in early posttreatment survivors was suboptimal. Interventions are needed to better implement and operationalize these guideline recommendations.

Substance use and mental health burden in head and neck and other cancer survivors: A National Health Interview Survey analysis. Cancer 2021; 128:112-121. [PMID: 34499355 DOI: 10.1002/cncr.33881] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 01/17/2021] [Accepted: 02/13/2021] [Indexed: 01/14/2023]
Abstract
BACKGROUND Tobacco dependence, alcohol abuse, depression, distress, and other adverse patient-level influences are common in head and neck cancer (HNC) survivors. Their interrelatedness and precise burden in comparison with survivors of other cancers are poorly understood. METHODS National Health Interview Survey data from 1997 to 2016 were pooled. The prevalence of adverse patient-level influences among HNC survivors and matched survivors of other cancers were compared using descriptive statistics. Multivariable logistic regressions evaluating covariate associations with the primary study outcomes were performed. These included 1) current cigarette smoking and/or heavy alcohol use (>14 drinks per week) and 2) high mental health burden (severe psychological distress [Kessler Index ≥ 13] and/or frequent depressive/anxiety symptoms). RESULTS In all, 918 HNC survivors and 3672 matched survivors of other cancers were identified. Compared with other cancer survivors, more HNC survivors were current smokers and/or heavy drinkers (24.6% [95% CI, 21.5%-27.7%] vs 18.0% [95% CI, 16.6%-19.4%]) and exhibited a high mental health burden (18.6% [95% CI, 15.7%-21.5%] vs 13.0% [95% CI, 11.7%-14.3%]). In multivariable analyses, 1) a high mental health burden predicted for smoking and/or heavy drinking (odds ratio [OR], 1.4; 95% CI, 1.0-1.9), and 2) current cigarette smoking predicted for a high mental health burden (OR, 1.7; 95% CI, 1.2-2.3). Furthermore, nonpartnered marital status and uninsured/Medicaid insurance status were significantly associated with both cigarette smoking and/or heavy alcohol use (ORs, 1.9 [95% CI, 1.4-2.5] and 1.5 [95% CI, 1.0-2.1], respectively) and a high mental health burden (ORs, 1.4 [95% CI, 1.1 -1.8] and 3.0 [95% CI, 2.2-4.2], respectively). CONCLUSIONS Stakeholders should allocate greater supportive care resources to HNC survivors. The interdependence of substance abuse, adverse mental health symptoms, and other adverse patient-level influences requires development of novel, multimodal survivorship care interventions.

Abstract
PURPOSE The prognostic significance of auricular location in cutaneous squamous cell carcinoma (cSCC) is controversial. We aimed to characterize risk factors for, and evaluate the cumulative incidence of, locoregional recurrence in a cohort of patients with primary auricular cSCC. METHODS The study design was a single-institution retrospective cohort review from 1/2007 to 12/2016. RESULTS Among 851 potentially eligible individuals, 178 patients with primary auricular cSCC met strict criteria for inclusion. Median follow-up was 32 months, 93% were AJCC 8th edition (AJCC8) stage I and 6% were AJCC8 stage II. Most underwent Mohs micrographic surgery (MMS; 97%) and the remainder underwent wide local excision ± parotidectomy ± neck dissection ± adjuvant therapy (3%). Recurrences occurred in seven patients (4%): six were local and one was regional. The 3-year cumulative incidence of local and regional recurrence for AJCC8 stage I-II tumors were 1% (95% CI 0-5%) and 0%, respectively. Among ten patients upstaged to pT3 disease who underwent MMS alone, none recurred locoregionally. Compared to their respective counterparts, advanced stage, PNI, and LVI associated with a significantly increased risk of locoregional recurrence. CONCLUSIONS Our findings suggest that auricular location may not be a significant risk factor for cSCC staging systems. In the absence of other risk factors, unimodal therapy appears adequate for patients with primary, stage I-II auricular cSCC. The prognostic significance of pT3 auricular cSCC stage due to depth of invasion alone should be evaluated further.

Abstract
OBJECTIVES To describe trends in cochlear implantation (CI) disparities in Texas using an all-payer database from 2010 to 2017. METHODS Texas Outpatient Surgical and Radiological Procedure Data, a public use data file, was accessed to analyze outpatient CI cases for Texas. Variables analyzed include patient age, sex, race/ethnicity, and insurance status. Population data from the American Community Survey generated CI utilization rates by patient demographic characteristics. RESULTS There were 6158 CI cases identified during the study period. The number of CI per year nearly doubled from 497 in 2010 to 961 in 2017. The majority of CI recipients were white (59.5%), male (51.9%), and privately insured (47.9%). All sub-populations statewide had more CI in 2017 compared to 2010, with the overall CI per 100 000 population increasing from 1.98 to 3.50 per 100 000 population. Patients over 75 demonstrated the greatest increase in the CI rate per 100 000 population, increasing from 4.60 in 2010 to 14.30 in 2017. Regarding race/ethnicity, all sub-populations noted an increase in the CI per 100 000 population, with white patients demonstrating the highest rate in 2017, at 4.36 CI per 100 000 population. Asian patients had a 502% increase in the CI rate (from 0.42 to 2.53), compared with 87.9%, 84.4%, and 69.2% increases for white, Black, and Hispanic populations, respectively. CONCLUSIONS CI became more widespread between 2010 and 2017, benefiting certain populations more than others. Black and Hispanic populations had lower CI per 100 000 population than their white peers, while patients >65 years of age accounted for the greatest increase in CI.

Blood-based biomarkers of human papillomavirus-associated cancers: A systematic review and meta-analysis. Cancer 2021; 127:850-864. [PMID: 33270909 PMCID: PMC8135101 DOI: 10.1002/cncr.33221] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 06/06/2020] [Accepted: 06/14/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Despite the significant societal burden of human papillomavirus (HPV)-associated cancers, clinical screening interventions for HPV-associated noncervical cancers are not available. Blood-based biomarkers may help close this gap in care. METHODS Five databases were searched, 5687 articles were identified, and 3631 unique candidate titles and abstracts were independently reviewed by 2 authors; 702 articles underwent a full-text review. Eligibility criteria included the assessment of a blood-based biomarker within a cohort or case-control study. RESULTS One hundred thirty-seven studies were included. Among all biomarkers assessed, HPV-16 E seropositivity and circulating HPV DNA were most significantly correlated with HPV-associated cancers in comparison with cancer-free controls. In most scenarios, HPV-16 E6 seropositivity varied nonsignificantly according to tumor type, specimen collection timing, and anatomic site (crude odds ratio [cOR] for p16+ or HPV+ oropharyngeal cancer [OPC], 133.10; 95% confidence interval [CI], 59.40-298.21; cOR for HPV-unspecified OPC, 25.41; 95% CI, 8.71-74.06; cOR for prediagnostic HPV-unspecified OPC, 59.00; 95% CI, 15.39-226.25; cOR for HPV-unspecified cervical cancer, 12.05; 95% CI, 3.23-44.97; cOR for HPV-unspecified anal cancer, 73.60; 95% CI, 19.68-275.33; cOR for HPV-unspecified penile cancer, 16.25; 95% CI, 2.83-93.48). Circulating HPV-16 DNA was a valid biomarker for cervical cancer (cOR, 15.72; 95% CI, 3.41-72.57). In 3 cervical cancer case-control studies, cases exhibited unique microRNA expression profiles in comparison with controls. Other assessed biomarker candidates were not valid. CONCLUSIONS HPV-16 E6 antibodies and circulating HPV-16 DNA are the most robustly analyzed and most promising blood-based biomarkers for HPV-associated cancers to date. Comparative validity analyses are warranted. Variations in tumor type-specific, high-risk HPV DNA prevalence according to anatomic site and world region highlight the need for biomarkers targeting more high-risk HPV types. Further investigation of blood-based microRNA expression profiling appears indicated.

Abstract
Objective To assess whether medication use, specifically statin, metformin, and aspirin, affects the growth of vestibular schwannomas (VSs). Study Design Retrospective case series. Setting Single tertiary care academic hospital. Subjects and Methods Patients were enrolled if they were diagnosed with sporadic VS and had at least 2 magnetic resonance imaging (MRI) studies at a minimum of 6 months apart prior to any intervention. Electronic medical records were reviewed for demographic and medication data. Tumor volumes on MRI studies were assessed via BrainLab iPlan. The primary endpoint was VS tumor growth, defined as a 20% increase in tumor volume, between consecutive MRI studies or between the first and last available MRI study. Predictors of volumetric growth, specifically statin, aspirin, or metformin use, were analyzed with t tests, chi-square test, univariate logistic regression, and multivariate logistic regression. Results A total of 387 patients met inclusion criteria, 53.5% of whom were women. For all patients, the mean age was 60.6 years (range, 18.2-89.2 years); the mean axial tumor diameter, 11.9 mm (range, 1.7-32.0 mm); and the mean tumor volume, 0.85 cm3 (range, 0.01-13.1 cm3). In review of the electronic medical record, 46 patients (11.9%) were taking metformin; 145 (37.5%), a statin; and 117 (30.2%), aspirin. Among patients taking metformin, 39.1% (18/46) exhibited volumetric growth, as opposed to 58.2% (198/340) of nonusers ( P = .014). Metformin (odds ratio, 0.497; P = .036) is significantly associated with reduced VS growth when controlling for aspirin, statin, and tumor size on multivariate logistic regression. Conclusion Metformin use is associated with reduced volumetric VS growth.

Abstract
BACKGROUND As Zimbabwe approaches epidemic control of HIV, programs now prioritize viral load over CD4 monitoring, making it difficult to identify persons living with HIV (PLHIV) suffering from advanced disease (AD). We present an analysis of cross-sectional ZIMPHIA data, highlighting PLHIV with AD and concurrent viral load suppression (VLS). METHODS ZIMPHIA collected blood specimens for HIV testing from 22,501 consenting adults (ages 15 years and older); 3,466 PLHIV had CD4 and VL results. Household HIV testing used the national serial algorithm, and those testing positive then received point-of-care CD4 enumeration with subsequent VL testing. We used logistic regression analysis to explore factors associated with concurrent AD and VLS (<1000 copies/mL). All analyses were weighted to account for complex survey design. RESULTS Of the 3,466 PLHIV in the survey with CD4 and VL results, 17% were found to have AD (CD4<200cells/mm3). Of all AD patients, 30% had VLS. Concurrent AD and VLS was associated with male sex (aOR 2.45 95%CI 1.61-3.72), older age (35-49 years [aOR 2.46 95%CI 1.03-5.91] and 50+ years [aOR 4.82 95%CI 2.02-11.46] vs 15-24 years), and ART duration (<6 months [aOR 0.46 95%CI 0.29-0.76] and 6-24 months [aOR 2.07 95%CI 1.35-3.17] vs more than 2 years). The relationship between sex and AD is driven by age with significant associations among men aged 25-34, (aOR 3.37 95%CI 1.35-8.41), 35-49 (aOR 5.13 95%CI 2.16-12.18), and 50+ (aOR 12.56 95%CI 4.82-32.72) versus men aged 15-24. CONCLUSIONS The percentage of PLHIV with AD and VLS illustrates the conundrum of decreased support for CD4 monitoring, as these patients may not receive appropriate clinical services for advanced HIV disease. In high-prevalence settings such as Zimbabwe, CD4 monitoring support warrants further consideration to differentiate care appropriately for the most vulnerable PLHIV. Males may need to be prioritized, given their over-representation in this sub-population.

Abstract
INTRODUCTION Studies have attempted to identify prognostic indicators for successful outcomes following bariatric surgery for obesity. The aim of this study was to determine whether the degree of obesity affects outcomes in patients who are morbidly obese (basal metabolic index, BMI, 40-49.9 kg/m2), super-obese (BMI 50-59.9 kg/m2) and super-super-obese (BMI greater than 60 kg/m2) undergoing restrictive or malabsorptive bypass procedures. MATERIAL AND METHODS Retrospective analysis of a prospectively maintained database was undertaken to include all consecutive laparoscopic adjustable gastric bands (LAGB), laparoscopic sleeve gastrectomies (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures since 2010. Patients with at least two years of follow-up were included. At each visit, the patient's weight, BMI, excess weight loss and comorbidity status were recorded. RESULTS A total of 353 patients (75% women) were included in the analysis; 65 (18.4%) underwent LAGB; 70 (19.8%) LSG and 218 (61.8%) LRYGB. At presentation, the median BMI for the morbidly obese sub-group was 47.2 kg/m2 for LAGB, 46.4 kg/m2 for LSG and 46.6 kg/m2 for LRYGB (P = 0.625); for the super-obese sub-group it was 53.2 kg/m2 for LAGB, 52.9 kg/m2 for LSG and 52.4 kg/m2 for LRYGB (P = 0.481); and for the super-super-obese sub-group 66.9 kg/m2 for (LAGB, 66.7 kg/m2 for LSG and 61.5 kg/m2 for LRYGB (P = 0.169). Percentage of excess weight loss at the end of two years was significantly higher in the morbidly obese and super-morbidly obese sub-groups undergoing LRYGB (median 68.5% and 69.5%, respectively; P < 0.001) than in the sub-groups undergoing LAGB and LSG. This was also reflected in the reduction of BMI achieved with bypass in the two sub-groups (P < 0.001). Complete diabetes remission was significantly higher in the morbidly obese and super-morbidly obese sub-groups undergoing LRYGB treatment (P < 0.05). Sleep apnoea, asthma and exercise tolerance had significantly improved in the super-morbidly obese undergoing LRYGB (P < 0.05). There was no significant difference between the three treatment groups in remission of hypertension; dyslipidaemia; gastro-oesophageal reflux disease and depression in all three BMI sub-groups. CONCLUSION The mid-term results for weight loss and resolution of obesity-related comorbidities is best achieved in super-obese patients undergoing LRYGB, without any significant increase in complications with this procedure as compared with LAGB and LSG.

Abstract
e17541 Background: Minority race, low-income status, tobacco dependence, alcohol abuse, and depression negatively impact overall survival among head and neck cancer (HNC) survivors. Understanding the prevalence and associations of these factors will inform the development of targeted HNC survivorship interventions. Methods: We pooled cross-sectional samples of HNC patients participating in the National Health Interview Survey from 1997-2016. Descriptive statistics were used to compare: 1) HNC survivors to age- and sex-matched adults without cancer (1:4) and 2) behavioral and psychologic conditions in HNC survivors by income status. Results: Mean age of the 918 HNC survivors was 64.8 years and 65.2% were male. Most HNC survivors were non-Hispanic white (85.3%); 7.6% were non-Hispanic black, 4.9% were Hispanic, and 2.2% were of other race and ethnicity. A substantial portion reported income below the poverty threshold (13.9%) and 5.0% consumed > 14 alcoholic drinks per week. Compared to adults without cancer (n = 3,612), a higher proportion (p < 0.05) of HNC survivors (n = 903) exhibited: current tobacco use (21.3% vs 17.4%); serious psychological distress (Kessler-6 score of ≥13; 6.9% vs 3.9%); depressive symptoms most or all of the time (14.1% vs 8.9%). There were particularly striking differences in the prevalence of these factors among HNC survivors by income. Specifically, a higher proportion of HNC survivors with income below the poverty threshold (n = 133) were non-Hispanic black (15.5% vs 5.8%) and exhibited current tobacco use (42.9% vs 18.6%), serious psychological distress (17.4% vs 5.7%) and depressive symptoms most or all of the time (25.3% vs 12.7%) compared to those at or above the poverty threshold (n = 646; all p < 0.05). Conclusions: HNC survivors experience a disproportionate burden of behavioral and psychologic health conditions compared to age- and sex-matched adults without cancer. Low-income status exacerbates these disparities. HNC survivors, especially those in low-income settings, require comprehensive survivorship care targeting these needs.

Abstract
There is a well-recognised association between hyperlipidaemia and acute pancreatitis. However, the role of hyperlipidaemia in modulating disease course is not clear. The aim of the study was to conduct a prospective study in acute pancreatitis to assess the relation between hyperlipidaemia and disease severity using current disease descriptors. The study population constituted 43 patients with acute pancreatitis, admitted during the calendar year 2001. There were 19 (44%) males. The median (range) age was 50 (21-86) years. Serum triglycerides, cholesterol and high-density lipids were measured on admission. Patients were followed-up for at least 6 months after discharge. Principal outcomes were relation between hyperlipidaemia and peri-pancreatic complications and end-of-episode disease severity. The results showed that hypertriglyceridaemia was present in 14 patients (33%). There was a significant difference in mean (SEM) serum triglyceride levels between patients with alcohol-induced pancreatitis compared with pancreatitis of other aetiologies [3.07 (1.0) mmol/l vs. 1.26 (0.11) mmol/l; p = 0.03, Fisher's exact test]. There was no correlation between admission hypertriglyceridaemia and admission APACHE II score (r(2) = 0.0015). Similarly, there was no correlation between triglyceride level and either pancreatic inflammatory complications or final outcome. In conclusion, this study has demonstrated that there was no significant correlation between hypertriglyceridaemia and either complications of disease or overall end-of-episode severity in this population of patients with acute pancreatitis.

Abstract
BACKGROUND Improved surgical techniques have contributed to a better outcome in kidney transplantation, and graft failure secondary to technical complications is unusual. METHODS We describe a surgical complication secondary to a rare and unexpected vascular anomaly in a pediatric renal transplant that resulted in considerable morbidity. RESULTS Our patient had a persistent sciatic artery as a dominant source of blood supply to the lower limb. Ligation of this vessel during anastomosis with the transplant kidney vasculature led to severe ischemic damage to the leg. CONCLUSION This vascular malformation, if undetected, can lead to serious complications.

Abstract
Data are sparse regarding the histological lesions associated with the primary nephrotic syndrome in adolescents. To our knowledge there are only two published articles that have specifically addressed the histopathological lesions that typify idiopathic nephrotic syndrome in the adolescent population. We reviewed our experience from the last 14 years of children between the ages of 12 and 18 years who were referred to our center for the evaluation of the nephrotic syndrome. A total of 29 adolescents met the inclusion criteria for this review. All patients were biopsied prior to the initiation of treatment. The sex ratio consisted of 52% males and 48% females and the racial breakdown was largely African-American, with 83% black adolescents, 7% Hispanic, and 10% Caucasian patients. Minimal change nephrotic syndrome (MCNS), the predominant lesion of children at an early age, was noted in only 20% of patients. The majority of patients (55.2%) had focal segmental glomerulosclerosis (FSGS); 7% had IgM nephropathy and 3.5% had diffuse mesangial hypercellularity. Only 7% of biopsied adolescents had membranoproliferative glomerulonephritis. Our results indicate that the most common lesion in this predominantly African-American patient population is FSGS, with only a small number showing MCNS. Thus, in our experience derived from a racially mixed population, adolescents with the nephrotic syndrome are less likely to have MCNS than younger children.

Abstract
Vascular thrombosis is one of the more difficult problems of pediatric renal transplantation; its etiology in multifactorial and, in most cases, it is irreversible. Vascular thrombosis accounts for 12.9% of graft failures in primary transplants in children and for 20% of graft failures in repeat transplants. Although it is seen most often in very young recipients and in recipients of kidneys from young donors, it can manifest in older children and adolescents as well. The peak incidence is seen in the first 48 h after transplantation; however, the event may be delayed until after the first week. When thrombosis occurs in an adolescent patients late in the course of transplantation, the pathogenesis is undetermined and immunosuppressive therapy is frequently implicated. This article describes a 19-yr-old patient with a three-antigen-matched cadaveric kidney who received cyclosporine and anti-thymocyte globulin for induction. Vascular thrombosis occurred after 7 d of initial good function. Eventually the graft was removed after attempts to re-establish vascularization failed. The patient received a second graft and despite an optimal six-antigen-match and different immunosuppression with tacrolimus, thrombosis recurred by the fifth postoperative day. The discussion that follows reviews the incidence and the factors implicated in the pathogenesis of this entity.

Abstract
There are only a few studies in the pediatric literature that have analyzed risk factors for renal failure in childhood lupus nephritis. This study reviewed the outcome of 56 children (4 to 18 yr of age) with lupus nephritis seen at the authors' institution over a 27-yr period (1965 to 1992), in relation to risk factors and therapy. All children underwent percutaneous renal biopsy before the institution of therapy. From 1965 to 1987, treatment for Class III and IV lupus nephritis consisted of high-dose pulse methylprednisolone, 500 mg daily for 10 days, followed by oral prednisone. From 1987 to 1992, IV cyclophosphamide was given monthly for 6 months and then every 3 months for a period of 3 yr for patients with Class III and Class IV disease. Of 56 children, 42% had Class IV and 21% had Class III histology at onset. The mean follow-up period was 4 yr and ranged from 0.5 to 20.3 yr. Life-table analysis showed that the cumulative proportion of patients surviving was 82.8% at 5 yr and 67.7% at 10 yr. Renal survival was 44.4% at 5 yr and 29% at 10 yr, after the initial diagnosis of lupus nephritis was made. Age at diagnosis, race, sex, initial serum creatinine level, and the presence of proteinuria, hypertension, and DNA antibody titers were reviewed with respect to disease progression, as was the histological class at diagnosis. The effect of the different therapies was also examined. Univariate analysis revealed a significant association of progression to ESRD with an elevated serum creatinine level (P = 0.021), decreased C3 complement (P = 0.024), hypertension (P = 0.053), and histological classification of Class IV lupus nephritis (P = 0.031). Multivariate analysis demonstrated that progression to ESRD was independently associated with an initial Class IV histology (relative risk, 1.78; P < 0.003), hypertension at presentation (relative risk, 1.67; P < 0.003), and a low C3 complement level in conjuction with a high creatinine level (relative risk, 1.52; P < 0.028). Among children with lupus nephritis, those with Class IV disease, hypertension, high creatinine levels, and low C3 complement levels at the time of diagnosis are at increased risk for ESRD. Initial histological classification of lupus nephritis was the most reliable prognostic factor for disease progression. This study was unable to detect a difference in outcome for the two treatment groups.

Abstract
The proposed mathematical formulation accounts for the role of the absorption and production mechanisms of the intracranial cavity. The transport barrier conduction is governed by the pressure gradients across them and hence by the instantaneous flow rates. The above mentioned mechanisms have now been incorporated into a previous model for static changes in the cranial cavity. The integrated model now evolved is simulated for a constant, bolus and sinusoidal infusion. The output has been correlated to experimentally observed trends. The results that emerge, point to a system whose response is sensitive to the nature of CSF volume perturbations. The production and absorption mechanisms function in a relay configuration, whose primary objective is to maintain the base line CSF pressure values when deviations in pressure occur. These mechanisms have a finite activation time which is dependent on the nature of the volume variation.

Abstract
A model has been developed to explain the development of stress under a constant infusion of fluid into the subarachanoid space. When the regulatory mechanism operates, the infused fluid is accommodated by the venous system and hence the tissue 'give' mechanism is under minimal stress. The necessity of maintaining a constant blood flow causes the blood vessel to dilate at higher CSF pressures. This puts the tissue 'give' mechanism under dual pressures, since it has to make room for the expanding ventricle as well as the dilating venous system. The theoretical model developed has been validated by experimental observations.
