: AKT expression is associated with degree of pathologic response in adenocarcinoma of the esophagus treated with neoadjuvant therapy.; Neoadjuvant chemoradiation (NCRT) has become standard in the treatment of locally advanced esophageal adenocarcinoma (EAC) with survival correlated to degree of pathologic response. The phosphatidyl inositol 3 kinase (PI3K)/protein kinase B (AKT)/mTOR pathway plays an important role in tumorgenesis and resistance. We sought to elucidate the role of this pathway in patients with EAC who received NCRT. After IRB approval, a prospective trial was initiated in which patients with EAC underwent endoscopic biopsies of normal and tumor tissue prior to instituting NCRT. Patients then proceeded to esophagectomy. The pre-treatment tissues underwent gene expression profiling. SAM method was used to analyze expression of AKT within normal and tumor tissue. Expression was then correlated to degree of pathologic response. One-hundred patients were consented for the study, of which 67 met final eligibility. Nineteen patient's tumors ultimately underwent gene expression profiling via microarray. The differential expression of all AKT isoforms in tumor tissue was markedly overexpressed compared to normal tissue (P=6×10(-5)). There were 3 patients designated as pNR, 6 as pPR, and 10 as pCR. Partial and non-responders had higher expressions of AKT compared to pCR with the non-responders consistently illustrated the highest expression of AKT (P=0.02). There was a significant correlation between individual isoforms of AKT-1, AKT-2, and AKT-3 and degree of pathologic response (P=0.002, 0.04, and 0.04 respectively). AKT is overexpressed in patients with AC of the esophagus. Moreover, pathologic response to NCRT may be correlated with degree of AKT expression. Additional data is needed to clarify this relationship to potentially add targeted therapies to the neoadjuvant regimen., Keywords: AKT expression, Esophageal cancer, Esophagectomy, Neoadjuvant therapy, Postoperative outcomes, Publication Note: This NIH-funded author manuscript originally appeared in PubMed Central at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4783740.

: Accuracy Of Neutrophil To Lymphocyte Ratio And Platelet To Lymphocyte Ratio As A Marker For Gastrointestinal Malignancies; Background: Accurate predictors of locally advanced and recurrence disease in patients with gastrointestinal cancer are currently lacking. Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) have emerged as possible markers for predicting recurrence in these patients. In this study, we sought to evaluate the utility of NLR and PLR in predicting the presence of regional nodal disease, metastasis and systemic recurrence in patients with gastrointestinal malignancies. Methods: We queried a comprehensive gastrointestinal oncology database to identify patients who had undergone surgery for a GI malignancy. NLR and PLR values were determined via a complete blood count (CBC). In patients treated with neoadjuvant therapy (NT) the NLR and PLR were calculated from CBCs before and after NT and in patients proceeding to surgery within 2 weeks pre-operatively. The associations between NLR and PLR and the clinicopathologic parameters (sex, age, tumor size, differentiation, positive lymph nodes, and metastatic disease) were assessed via chi(2) or Fisher's exact tests where appropriate. All the tests were two-sided, and P<0.05 was considered statistically significant. Results: We identified 116 patients diagnosed with gastrointestinal malignancies. There were 76 (65.5%) males and 40 (34.5%) females with an average age of 69.4 +/- 10.7 years. The mean follow up was 14.1 +/- 15.5 months. We identified 49 (42.2%) esophageal, 34 (29.3%) pancreatic, 14 (12.1%) colorectal, 13 (11.2%) gastric, and 6 (5.2%) biliary cancers. There were 36 (31.0%) patients with node negative disease, 52 (44.8%) with node positive and 28 (24.2%) with metastatic disease at surgery. Of the metastatic patients 4 (3.4%) were found at staging laparoscopy and 24 (20.6%) were diagnosed pre-operatively. The median NLR for LN-patient's was 1.78 (0.23-8.2) and for LN+ and metastatic patients was 4.69 (2.27-36), P<0.001. The median PLR for LN-patient's was 123.03 (14-257.69) and for LN+ and metastatic patients was 212.42 (105.45-2,185.18), P<0.001. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for a NLR >2.25 was 98.8%, 72.2%, 89%, and 96% respectively. The sensitivity, specificity, PPV, and NPV for PLR >140 was 95%, 78%, 90%, and 88% respectively. Utilizing both NLR and PLR the sensitivity, specificity, PPV and NPV was increased. Conclusions: Elevation of NLR and PLR can be used to help identify patients with advanced disease GI malignancies and recurrences after surgery. Additionally, failure of normalization of NLR and PLR 3-month post-surgical resection may indicate early recurrence or persistent disease. Individually, NLR has a higher sensitivity and negative predictive value while PLR has a higher specificity and positive predictive value for distinguishing metastatic disease and node positivity. The combination of NLR and PLR has the highest accuracy of predicting advanced disease among all gastrointestinal malignancies., Keywords: squamous-cell carcinoma, colorectal-cancer, immune-response, lung-cancer, advanced gastric-cancer, esophageal cancer, gastrointestinal malignancies, Neutrophil to lymphocyte ratio (NLR), node metastasis, pancreatic-cancer, platelet to lymphocyte ratio (PLR), postoperative survival, useful predictor, Publication Note: The publisher’s version of record is available at https://doi.org/10.21037/jgo.2018.08.05

: Achalasia; INTRODUCTION: Achalasia is a condition that occurs when the lower esophageal sphincter (LES) fails to properly relax, combined with slowing/failure of esophageal peristalsis. This is seen clinically by not allowing solids and liquids to pass easily into the stomach. Achalasia is not historically associated with morbid obesity, yet dual treatment of morbid obesity and achalasia is becoming more prominent due to the worldwide obesity epidemic. PRESENTATION OF CASE: Achalasia is typically a disease that affects non-obese adults over the age of 55, which makes the discussion of this case report unique in that our patient is a 23 year-old woman who successfully underwent per-oral endoscopic myotomy (POEM) in preparation for a future laparoscopic sleeve gastrectomy. There is sparse literature on combining laparoscopic Heller myotomy (LHM) and partial fundoplication versus POEM with either restrictive or malabsorptive minimally invasive bariatric procedures. DISCUSSION: LHM and partial fundoplication have long been considered the gold standard surgical treatment for achalasia by disrupting both the longitudinal and circular muscle layers of the LES. The newer, less invasive, POEM technique will be compared to the gold standard LHM and Dor fundoplication in this uncharacteristically young morbidly obese achalasia patient. The decision to pursue a laparoscopic sleeve gastrectomy over a laparoscopic Roux-en-Y gastric bypass was multifactorial due to the patient's concerns regarding malabsorption of vitamins and nutrients in the event of a future pregnancy. CONCLUSION: The patient has already undergone a POEM procedure, which was chosen to maintain the gastric fundus, cardia, and gastroesophageal junction (GEJ) architecture as opposed to a LHM with Dor fundoplication, which would have altered the anatomy, thus making a concomitant laparoscopic sleeve gastrectomy an unfeasible option.

: Anal Squamous Intraepithelial Lesions and HPV Among Young Black Men Who Have Sex with Men.; Limited data are available on anal squamous intraepithelial lesions (ASILs) and anal human papillomavirus (HPV) infection in young, Black populations. The purpose of this study was to examine the prevalence of and relationships between ASILs and high-risk HPV infection in a young (<30 years of age), predominantly Black, men who have sex with men (MSM) population. Results of anal cytology and HPV DNA were gathered for 83 individuals. Forty-two percent of individuals (35) had atypical squamous cells of undetermined significance and 33% (27) had low-grade squamous intraepithelial lesion by cytology. Only 9% tested positive for both high-risk HPV subtypes 16 and 18. Low rates of infection with both HPV types 16 and 18 may provide further evidence that we should continue to vaccinate young, Black MSM against HPV., Keywords: HIV/AIDS, Cancer, Epidemiology, Health screening, Men who have sex with men (MSM), Prevention, Grant Number: R01 MH100021, Publication Note: This NIH-funded author manuscript originally appeared in PubMed Central at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5278831.

: CT-based assessment of visceral adiposity and outcomes for esophageal adenocarcinoma.; Various methods of quantifying and correlating obesity to outcomes for patients with esophageal adenocarcinoma (EA) have been evaluated. Published data suggest that quantification of adiposity may be more accurate than body mass index (BMI) as a prognostic factor. We report our analysis of adiposity as a prognostic factor in a series of patients with EA. This single institution retrospective review included patients with EA who underwent esophagectomy from 1994-2008. Patients with BMI <20 were excluded. Using the preoperative CT scan, the visceral (VFA), subcutaneous (SFA), and total abdominal fat (TFA) areas were calculated. Each was contoured on a Siemens Leonardo workstation at the level of the iliac crest (L4/5). The Hounsfield threshold was -30 to -130. Outcomes were analyzed using Kaplan-Meier method and log-rank analysis. Multivariate analysis (MVA) was performed using the Cox proportion hazard regression model. We identified 126 patients for the analysis. There were no statistically significant differences in overall survival or disease-free survival between groups above and below the medians for TFA, SFA, or VFA/SFA ratio. However, an increase in VFA was significantly associated with worsened OS and DFS when we further classified patients into quartiles. Patients with VFA ≥182 cm had larger tumor size (P=0.016), fewer involved lymph nodes (P=0.047), longer operating times (P=0.032), and were more likely to be males (P=0.042). Published data have demonstrated an association between treatment outcomes and degree of adiposity; our study found a correlation between VFA and OS and DFS in patients with EA. Median TFA, SFA, and VFA/SFA were not prognostic on MVA. While VFA >182 cm was associated with larger tumors, there were also fewer lymph nodes harvested in this group., Keywords: GI tract, Obesity surgery, Overweight, Treatment outcomes, Visceral obesity, Publication Note: This NIH-funded author manuscript originally appeared in PubMed Central at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5674266.

: Callosal Apraxia; Loss of ability of the left upper limb (LUL) to correctly produce spatial and temporal components of skilled purposeful movements was reported 34years ago in a woman with a callosal infarction. To learn about recovery, we recently reexamined this woman. This woman was tested for ideomotor apraxia by asking her to pantomime to command and to seeing pictures of tools. Whereas she performed normally with her right upper limb, her LUL remained severely apraxic, making many spatial (postural and movement) errors. Initially, she did not reveal loss of finger-hand deftness (limb-kinetic apraxia), and when tested again with the coin rotation task, her left hand performance was normal. Without vision, she could name objects placed in her left hand but not name numbers written in this hand. Since this woman had a callosal lesion, failure to recover cannot be accounted for by left hemisphere inhibition of her right hemisphere. Although failure for her LUL to improve may have been related to not using her LUL for skilled actions, her right hemisphere was able to observe transitive actions, and this failure of her LUL to produce skilled purposeful movements suggests her right hemisphere may have not had the capacity to learn these movement representations. Without vision, her ability to recognize objects with her left hand, but not numbers written on her left palm, suggests graphesthesia may require that her left hand did not have access to movement representations important for programming these numbers when writing., Keywords: agraphesthesia, agraphia, Corpus callosum, ideomotor apraxia, lesions, limb kinetic apraxia, movement, pantomime, praxis, representations, Publication Note: The publisher's version of record is available at https://doi.org/10.1080/13554794.2016.1148743

: Caring for Older Adults with the Human Immunodeficiency Virus; Increasing proportions of older adults are living with the human immunodeficiency virus (HIV). It is estimated that more than 50% of individuals with HIV in the United States are aged 50 and older. Part of this group consists of individuals who have aged with chronic HIV infection, but a large proportion also results from new HIV diagnosis, with approximately 17% of new HIV diagnoses in 2013 occurring in individuals aged 50 and older. Although many of the recommendations on management of HIV infection are not age-specific, individuals with HIV aged 50 and older differ from their younger counterparts in many aspects, including immune response to antiretroviral therapy, multimorbidity, antiretroviral toxicities, and diagnostic considerations. This article outline these differences, offers a strategy on how to care for this unique population, and provides special considerations for problem-based management of individuals with HIV aged 50 and older., Keywords: HIV/AIDS, Aging, Multimorbidity, Preferred Citation: Provider: John Wiley & Sons, Ltd Content:text/plain; charset="UTF-8" TY - JOUR AU - Sangarlangkarn, Aroonsiri AU - Appelbaum, Jonathan S.

: Clinical Fate Of T0n1 Esophageal Cancer; The long-term survival for patients with locally advanced esophageal cancer (EC) remains poor despite improvements in multi-modality care. Neoadjuvant chemoradiation (NCR) followed by surgical resection remains pivotal in the management of patients with EC. However, the outcome of patients whose primary tumor exhibits a complete response with residual regional nodal disease (T0N1) remains unclear as well as the role for adjuvant therapy. Utilizing the National Cancer Database we identified patients with EC who underwent NCR followed by esophagectomy who had subsequent pathology of T0N1. Baseline univariate comparisons of patient characteristics were made for continuous variables using both the Mann-Whitney U and Kruskal Wallis tests as appropriate. Pearson's Chi-square test was used to compare categorical variables. Unadjusted survival analyses were performed using the Kaplan-Meier method comparing survival curves with the log-rank test. All statistical tests were two-sided and alpha (type I) error <0.05 was considered statistically significant. We identified 7,116 patients diagnosed with EC; 6,235 (87.6%) adenocarcinoma (AC), 881 (12.4%) squamous cell carcinoma (SCC) with a median age of 62 [21-88] years. There were 6,031 (84.8%) males and 1,085 (15.2%) females. R0 resections were achieved in 6,668 (93.7%) patients and this correlated to improved median survival 39.5 (R0) and 20.1 (R1) months respectively, P<0.001. The median nodes harvested were 13 [0-83] with a mean positive LN's of 1.4 +/- 2.9. Pathologic complete response (pCR) was achieved in 1,334 (18.7%), partial response (pPR) 2,812 (39.5%) and non-response (pNR) 2,970 (41.7%). There were 230 (3.2%) patients deemed as pathologic T0N1. The median survival of patients with pCR was 61.7 months compared to 32.1 months in the T0N1 patients P<0.001. T0N1 patients did not demonstrate an improved survival over T1/2 patients who had a median survival of 30.5 months, P=0.79. However, T0N1 did reveal an improved survival over T3/4 patients who had a median survival of 24.6 months, P=0.02. Adjuvant chemotherapy in T0N1 did not provide a benefit in survival, median survival adjuvant versus no adjuvant 30.8 vs. 32.1 months respectively, P=0.08. Multivariate analysis in T0N1 patients demonstrated only number of LN's positive, and histology SCC vs. ACC as predictive of survival, HR, 1.22, 95% CI: 1.10-1.36, P<0.001; HR, 0.43, 95% CI: 0.24-0.75, P=0.003, respectively. Patients with EC who exhibit a pathologic T0N1 after NCR have oncologic fates similar to node positive patients. Patients with pCR of the primary tumor and regional lymph nodes continue to demonstrate significant survival benefits over all remaining pathologic cohorts., Keywords: surgery, chemotherapy, complete pathological response, long-term survival, National Cancer Database (NCDB), neoadjuvant therapy, preoperative chemoradiotherapy, T0N1 esophageal cancer (T0N1 EC), Publication Note: The publisher’s version of record is available at https://doi.org/10.21037/jgo.2018.08.08

: Correlation Of Tumor Size And Survival In Pancreatic Cancer; Background: Neoadjuvant therapy (NT) for resectable pancreatic adenocarcinoma (PAC) continues to be debated. We sought to establish the relationship between pancreatic tumor size, neoadjuvant chemotherapy (NCT), neoadjuvant chemoradiation (NCRT), and definitive surgery (DS) on survival. Methods: Utilizing the National Cancer Database we identified patients with PAC who underwent NT and DS. Patient characteristics and survival were compared with Mann-Whitney U, Pearson's Chi-square, and the Kaplan-Meier method. Multivariable analysis (MVA) was developed to identify predictors of survival. All tests were two-sided and a <0.05 was significant. Results: We identified 11,707 patients: 9,722 patients with tumors >2 cm and 1,985 with tumors =2 cm. There were 523 patients treated with NCT, 559 treated with NCRT, and 10,625 DS. Patients with tumors >2 cm were more likely to have higher T-stage, P<0.001, positive lymph nodes, P<0.001, poor histologic grade, P<0.001, and R1 resections, P<0.001. The median survival for patients with tumors =2 cm was 30.6 months compared to 20.5 months for those whose tumors were >2 cm, P<0.001. In the >2 cm groups the median survival for NCT, NCRT, and DS was 22.9, 25.8 and 21.3 months, P=0.01. MVA revealed that age, Charlson/Deyo score, N-stage, grade, tumor size >2 cm, R0 resection, and NT were predictors of survival. Ninety-day mortality was worse in both the NCT and NCRT compared to DS, P<0.001. Conclusions: The size of pancreatic cancer correlates to pathologic stage and overall survival. Tumors >2 and <2 cm benefited from a NT. However, the 90-operative mortality was significantly worse in those patients receiving NT., Keywords: adjuvant chemotherapy, neoadjuvant therapy, adenocarcinoma, gemcitabine-based chemoradiation, multimodality therapy, neoadjuvant therapy (NT), Pancreatic cancer, pancreaticoduodenectomy, postoperative complications, preoperative gemcitabine, resection, score matched analysis, tumor size, Publication Note: The publisher’s version of record is available at https://doi.org/10.21037/jgo.2018.08.06

: Early goal-directed therapy in severe sepsis and septic shock; Prior to 2001 there was no standard for early management of severe sepsis and septic shock in the emergency department. In the presence of standard or usual care, the prevailing mortality was over 40-50 %. In response, a systems-based approach, similar to that in acute myocardial infarction, stroke and trauma, called early goal-directed therapy was compared to standard care and this clinical trial resulted in a significant mortality reduction. Since the publication of that trial, similar outcome benefits have been reported in over 70 observational and randomized controlled studies comprising over 70,000 patients. As a result, early goal-directed therapy was largely incorporated into the first 6 hours of sepsis management (resuscitation bundle) adopted by the Surviving Sepsis Campaign and disseminated internationally as the standard of care for early sepsis management. Recently a trio of trials (ProCESS, ARISE, and ProMISe), while reporting an all-time low sepsis mortality, question the continued need for all of the elements of early goal-directed therapy or the need for protocolized care for patients with severe and septic shock.

: Emergency incarcerated obturator hernia repair with biologic mesh in a male patient after ipsilateral hip disarticulation; An obturator hernia is an uncommon form of abdominal hernia that is difficult to diagnose due to its non-distinct presentation. This case investigates an emergency treatment of an obturator hernia presenting in a patient with an ipsilateral hip disarticulation in a 266-bed community hospital. A 53-year old man with a history of a left hip disarticulation 3-weeks prior presented to the emergency department with fever, nausea, vomiting, and diarrhea for the past 5-days. An elevated WBC and presence of gas within the hip stump on CT led to an emergency operation to rule out necrotizing fasciitis within the stump. Opening of the stump incision revealed two herniated loops of small bowel corresponding to the left obturator foramen, revealing the diagnosis of an incarcerated obturator hernia. The bowel was reduced and secured within the hip stump and the defect was covered with Strattice biologic mesh. Obturator hernias are rare and can involve vague symptoms, but it is essential to make an accurate diagnosis and repair the defect on an emergency basis. Obturator hernias may appear in the setting of a hip disarticulation, being caused by iatrogenic anatomic alteration, and can be treated in a community acute care hospital. Being aware of the possibility of obturator foramen herniation and bowel incarceration as part of the differential diagnosis for patients with abdominal pain after a prior hip disarticulation can facilitate prompt diagnosis and reduce morbidity and mortality., Keywords: Emergency, Hip disarticulation, Incarcerated bowel, Mesh repair, Obturator foramen, Obturator hernia, Publication Note: This NIH-funded author manuscript originally appeared in PubMed Central at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5479947.

: Emergency splenectomy for trauma in the setting of splenomegaly, axillary lymphadenopathy, and incidental B-cell chronic lymphocytic leukemia; The spleen is the most commonly injured intra-abdominal solid organ following blunt trauma. B-cell chronic lymphocytic leukemia (CLL) is the most common leukocytic dyscrasia affecting adults in Western countries. Splenomegaly with axillary and retroperitoneal lymphadenopathy are common physical findings. This case investigates an emergency splenectomy in a community hospital involving a 45-year-old man with blunt abdominal trauma following an assault with incidental splenomegaly and axillary lymphadenopathy, with surgical pathology findings of B-cell CLL. A 45- year-old man without past medical or family history who was the victim of an assault presented to the emergency department 6h later with left upper quadrant pain and radiation to the left flank and a positive Kehr sign. An elevated absolute lymphocyte count above 7×10 and CT confirmation of a Grade V splenic laceration with splenomegaly, axillary lymphadenopathy, with hemodynamic compromise led to an exploratory laparotomy and emergency splenectomy regardless of the potential for malignancy. Hemoperitoneum with blunt splenic injury (BSI) caused by abdominal trauma with hemodynamic instability should be treated with exploratory laparotomy and splenectomy even in the face of potential malignancy with splenomegaly and axillary lymphadenopathy. An appropriate oncologic work up and treatment can be provided after the emergency intervention. An emergency splenectomy is an appropriate operative intervention for a grade V splenic laceration with hemoperitoneum, splenomegaly, and axillary lymphadenopathy regardless of the potential for a neoplastic process such as B-cell CLL. Post-splenectomy vaccinations and oncologic follow-up for systemic chemotherapy should be facilitated after recovery., Keywords: Abdominal, Blunt, CLL, Splenectomy, Splenomegaly, Trauma, Publication Note: This NIH-funded author manuscript originally appeared in PubMed Central at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5499106.

: Emergency total proctocolectomy in an uninsured patient with Familial Adenomatous Polyposis Syndrome and acute lower gastrointestinal hemorrhage in a community hospital; INTRODUCTION: Rectal bleeding is the most common symptom of Familial Adenomatous Polyposis (FAP). This case investigates the efficacy of emergency surgery for FAP with total proctocolectomy end ileostomy for recurrent lower gastrointestinal (GI) hemorrhage in an uninsured patient in a 266-bed community hospital. The optimal treatment for FAP with acute lower GI hemorrhage and hemodynamic compromise unresponsive to conservative management is unclear. PRESENTATION OF CASE: A 41-year-old uninsured African American man with no past medical or family history presented to the emergency department with hematochezia lasting three days. A clinical diagnosis of FAP made on colonoscopy with biopsies revealed villous and tubulovillous adenomas without dysplasia. After blood products resuscitation, an emergency total proctocolectomy with end ileostomy was performed. A staged ileal J pouch to anal anastomosis and creation of protective loop ileostomy was performed months later after securing state funding. A final loop ileostomy reversal occurred six weeks later. His self reported quality of life is improved. DISCUSSION: Lower GI hemorrhage from FAP unresponsive to blood products may require emergency total proctocolectomy and end ileostomy with a staged ileal J pouch to anal anastomosis, which can be done in a community acute care hospital for an uninsured patient. CONCLUSION: A total proctocolectomy is feasible in the emergency setting in an uninsured patient with lower GI bleeding and FAP.
