Socioeconomic Disparities in Anal Cancer: Effect on Treatment Delay and Survival.

BACKGROUND: Socioeconomic inequities have implications for access to health care and may be associated with disparities in treatment and survival. OBJECTIVE: To investigate the impact of socioeconomic inequities on time to treatment and survival of anal squamous-cell carcinoma. DESIGN: This is a retrospective study using a nationwide data set. SETTINGS: The patients were selected from the National Cancer Database and enrolled from 2004 to 2016. PATIENTS: We identified patients with stage I to III squamous-cell carcinoma of the anus who were treated with chemoradiation therapy. MAIN OUTCOMES MEASURES: Socioeconomic factors, including race, insurance status, median household income, and percentage of the population with no high school degrees, were included. The association of these factors with treatment delay and overall survival was investigated. RESULTS: A total of 24,143 patients who underwent treatment for grade I to III squamous-cell carcinoma of the anus were identified. The median age was 60 years, and 70% of patients were women. The median time to initiation of treatment was 33 days. Patients from zip codes with lower median income, patients with a higher percentage of no high school degree, and patients with other government insurance followed by Medicaid insurance had treatment initiated after 60 days from diagnosis. Kaplan-Meier survival analysis showed that the late-treatment group had worse overall survival compared to the early treatment group (98 vs 125 months; p < 0.001). LIMITATIONS: No detailed information is available about the chemoradiotherapy regimen, completion of treatment, recurrence, disease-free survival, and individual-level socioeconomic condition and risk factors. CONCLUSION: Patients from communities with lower median income, level of education, and enrolled in public insurance had longer time to treatment. Lower socioeconomic status was also associated with poorer overall survival. These results warrant further analysis and measures to improve access to care to address this disparity.

DESIGUALDADES SOCIOECONMICAS EN CASOS DE CNCER ANAL EFECTOS EN EL RETRASO DEL TRATAMIENTO Y LA SOBREVIDA: ANTECEDENTES:Las desigualdades socio-económicas tienen implicaciones en el acceso a la atención médica y pueden estar asociadas con disparidades en el tratamiento y la sobrevida.OBJETIVO:Indagar el impacto de las desigualdades socio-económicas sobre el tiempo de retraso en el tratamiento y la sobrevida en casos de carcinoma a células escamosas del ano (CCEA).DISEÑO:Estudio retrospectivo utilizando un conjunto de datos a nivel nacional.AJUSTES:Todos aquellos pacientes inscritos entre 2004 a 2016 y que fueron seleccionados de la Base Nacional de Datos sobre el Cáncer.PACIENTES:Identificamos pacientes con CCEA en estadíos I-III y que fueron tratados con radio-quimioterápia.PRINCIPALES MEDIDAS DE RESULTADOS:Se incluyeron factores socio-económicos tales como la raza, el tipo de seguro de salud, el ingreso familiar medio y el porcentaje de personas sin bachillerato de secundaria (SBS). Se investigó la asociación entre estos factores con el retraso en iniciar el tratamiento y la sobrevida global.RESULTADOS:Se identificaron un total de 24.143 pacientes que recibieron tratamiento para CCEA estadíos I-III. La mediana de edad fue de 60 años donde 70% eran de sexo femenino. La mediana del tiempo transcurrido desde el diagnóstico hasta el inicio del tratamiento fue de 33 días. Los pacientes residentes en zonas de código postal con ingresos medios más bajos, con un mayor porcentaje de individuos SBS y los pacientes con otro tipo de seguro gubernamental de salud, seguidos del seguro tipo Medicaid iniciaron el tratamiento solamente después de 60 días al diagnóstico inicial de CCEA. El análisis de Kaplan-Meier de la sobrevida mostró que el grupo de tratamiento tardío tuvo una peor supervivencia general comparada con el grupo de tratamiento precoz o temprano (98 frente a 125 meses; p <0,001).LIMITACIONES:No se dispone de información detallada sobre el tipo de radio-quimioterapia utilizada, ni sobre la finalización del tratamiento o la recurrencia, tampoco acerca de la sobrevida libre de enfermedad ni sobre las condiciones socio-económicas o aquellos factores de riesgo a nivel individual.CONCLUSIÓN:Los pacientes de comunidades con ingresos medios más bajos, con un nivel de educación limitado e inscritos en un seguro público tardaron mucho más tiempo en recibir el tratamiento prescrito. El nivel socio-económico más bajo también se asoció con una sobrevida global más baja. Los presentes resultados justifican mayor análisis y medidas mas importantes para mejorar el acceso a la atención en salud y poder afrontar esta disparidad. (Traducción-Dr. Xavier Delgadillo ).

Isolation and identification of Saccharomyces cerevisiae for fermentation of rice polishing in Livestock feeding.

Biomass of Saccharomyces cerevisiae wasenhancedin rice polishing by fermentation to increase protein contents of feedfor its use in livestock. Broth culture of Saccharomyces cerevisiae (2.6×108CFU/mL) was prepared from culture obtained by continuous streaking. The isolated culture was identified morphologically by Gram staining and confirmed by biochemical characteristics. Rice polishing was sieved to remove larger particles. Then it was distributed to 4 treatments in triplicates. Treatments were represented as rice polishing (RP), rice polishing plus Saccharomyces culture (RPSC), rice polishing plus ammonium sulphate (RPAS), rice polishing plus Saccharomyces culture plus ammonium sulphate (RPSCAS).Fermentation was provided for 144 hours at 320C,while samples were collected after every 24 hours. Samples were dried, ground and subjected to proximate analysis. It was observed that protein content was increased from 11% to 21.51% and maximum increment was obtained after 144 hours of incubation in RPSC treatment. Ether extract and ash were increased from 14% and 10% to 16.96% and 11.11% in RPSCAS respectively. A significant reduction in neutral detergent fiber was observed after fermentation. It is concluded that Saccharomyces cerevisiae has potential to improve mineral and protein contents of rice polishing by fermentation process with or without addition of nitrogen source.

The Impact of Delayed Surgical Care on Patient Outcomes With Alimentary Tract Perforation: Insight From a Low-Middle Income Country.

Introduction In-patient delay is associated with increased mortality in patients with alimentary tract perforations. Access to surgical care is a glaring health issue in low-middle income countries (LMICs), where patient presentation is also delayed for a myriad of reasons, which can be broadly categorized as social/cultural, financial, and structural in their nature. The impact these delays have on surgical outcomes in low-middle income countries is not known. Methods A retrospective cohort study of patients who underwent emergency laparotomy for alimentary tract perforation from July 2015 to June 2018 was conducted at a tertiary care hospital in Karachi, Pakistan. Time was recorded in two variables: symptom onset to emergency room presentation (ERT) and emergency room to operation room time (ORT). Results Overall, 80 patients were included in the study. The 12 (15%) patients who expired were significantly older (57 ± 17.7 years of age), had a higher Charlson Comorbidity Index and had longer ORT [median ORT in hours-discharged vs expired: 8.2 (IQR 5-15) vs 16 (IQR 12-28) p=0.02]. ERT was also longer but lacked statistical significance [median ERT in hours-discharged vs expired: 24 (IQR 22-72) vs 48 (IQR 24-120) p=0.19]. Multivariable logistic regression analysis revealed ORT to be significantly associated with mortality [odds ratio (OR): 1.02, 95% confidence interval (CI): 1.003-1.041; p=0.02]. Adjusted Cox regression analysis showed that each hour of ORT increased the risk of mortality by 1.5% [hazard ratio (HR) 1.015, 95% CI 1.001-1.030]. Conclusion Inpatient delays increased the risk of mortality for patients undergoing emergency laparotomy for alimentary tract perforation. Larger sample sizes and prospective studies are needed to better understand this relationship and the impact pre-hospital delays have on outcomes.

Anal Adenocarcinoma Arising From a Fistula-in-Ano: A Case Report.

Crohn's disease (CD) is an inflammatory disease that can affect any portion of the gastrointestinal tract (GIT). Although it can present with a number of complications, perianal fistulae are among the most common consequences in patients with CD. In very rare cases, these patients can develop fistula-associated anal adenocarcinoma (FAAA). In this case report, we discuss a 72-year-old man with a long-term history of CD complicated by perianal fistulae, which failed medical and surgical management, ultimately presenting with acute anal pain in the outpatient setting. The physical examination revealed a seton traversing through a fistula surrounded by circumferential granulation tissue suspicious for malignancy. A biopsy of the tissue confirmed grade 3 mucinous-type infiltrating adenocarcinoma of the perianal skin. The patient was diagnosed with an anal verge malignancy associated with a fistula in the context of long-standing CD, and MRI staging demonstrated a T3N1 lesion with potential left inguinal node involvement. He completed neoadjuvant chemo-radiotherapy using capecitabine for five weeks with minimal tumor response, and subsequently, an abdominoperineal resection (APR) was performed with patient discharge on the fifth post-procedure day. Post-operative chemotherapy with oxaliplatin/leucovorin/fluorouracil was administered with minimal complications. Although rare, this report demonstrates the importance of consistent follow-up and mitigation of risk factors in patients with CD, along with the significance of prompt multimodal treatment in the event of developing FAAA.

Plasmablastic Lymphoma Presenting With Rectosigmoid Perforation in a Human Immunodeficiency Virus-Positive Patient.

Plasmablastic lymphoma (PBL) is a rare variant of diffuse large B-cell lymphoma (DLBCL) associated with human immunodeficiency virus (HIV)-positive patients. It accounts for only 2% of all acquired immune deficiency syndrome (AIDS)-related lymphomas (ARLs). We present the case of a 45-year-old male who presented to the emergency department (ED) with a three-month history of abdominal pain, diarrhea, and unintentional 50-lb weight loss. On an earlier presentation to the ED three months prior, the patient was diagnosed with norovirus and Helicobacter pylori infection and received outpatient treatment without resolution of his symptoms. This prompted further investigation with a CT of the abdomen and pelvis with IV contrast that revealed severe sigmoid colitis with pneumoperitoneum and a pericolonic air-containing fluid collection, consistent with a contained perforation with abscess formation. He was admitted, resuscitated, and initially treated with antibiotics and parenteral nutrition. The patient underwent a laparoscopic converted to open anterior resection with end colostomy. Pathology revealed HIV-related PBL. He was subsequently treated with dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (DA-EPOCH-R) chemotherapy regimen and an autologous stem cell transplant. Despite its rare association with HIV, PBL should be considered a differential diagnosis for HIV-positive patients who present with gastrointestinal (GI) pathology, and additional investigations should be conducted if symptoms do not resolve despite appropriate medical management at the time.
