Food Sensitivity and Laryngopharyngeal Reflux: Preliminary Observations.

Reflux is an expensive, high prevalence disease that affects at least half of patients with laryngeal and voice disorders. Approaches to treatment of laryngopharyngeal reflux include medical, lifestyle, dietary, and surgical treatment options.2 We review four patients who had persistent reflux signs and symptoms on appropriate lifestyle including elevating head of bed and dietary modifications, as well as antacid, H2 receptor blockers, and proton pump inhibitor therapy, who improved substantially on specific food avoidance diets. This raises food sensitivity as a possible factor in patients with intractable LPR.

The Use of Clozapine in the Serious Mental Illness Patients Enrolled in an Assertive Community Treatment Program.

Introduction Health care cost is projected to reach 20% of the nation's gross national product (GNP) by 2016. 6.2% of this is from mental health. The National Institute of Mental Health (NIMH) estimates the prevalence of serious mental illness (SMI) at 13.1 million or 5.2% of American adults age 18 or over. Hence, mental health care cost for this patient population is significant. Patients with SMI involved in an Assertive Community Treatment (ACT) program are individuals who experience the most intractable symptoms and the greatest level of dysfunction from their mental illness. These individuals typically are institutionalized in a long-term facility such as the state hospital. Clozapine has shown superior efficacy over first- and most second-generation antipsychotics in both treating treatment-resistant and non-treatment-resistant schizophrenia which has been supported by several large trials. There is also evidence of its efficacy in suicidality, aggression and substance misuse. In fact, clozapine has been approved by the FDA for use in refractory schizophrenia and suicidality in schizoaffective disorder. Due to the risk of agranulocytosis, clozapine is underutilized. The purpose of this study is to conduct a retrospective cohort study through chart review to analyze whether the addition of clozapine to ACT treatment of SMI patients in a community hospital from 2008 to 2018 led to decreased frequency of hospitalizations and increased clinical stability. Materials and methods A retrospective study using electronic medical record (EMR) of patients ages 20 and above who were enrolled in the ACT program at a community hospital from December 1, 2008 to December 31, 2018. Variables were collected from the EMR and de-identified during data collation. Analysis was performed using SPSS software package. Results A total of 179 patients enrolled in the ACT program and their data was extracted from the EMR. Twenty-five (62.5%) of these patient enrollments were on clozapine. They were made up of 53.6% male, 81.9% White/Asian, 18.1% Black; 44.1% ages between 36 to 50 years old, 30.2% were aged 18 to 35 years old, and 25.7% greater than 50 years old. There was no difference in age, sex, race, ethnicity, and insurance type in ACT program between those using clozapine and those not on clozapine. There was a higher proportion of psychiatric hospitalizations among clozapine users compared with the non-clozapine user group (62.5% vs 41.5%, p = 0.019). However, the two groups did not differ from one another in terms of psychiatric emergency visits (p = 0.128) or frequency of ACT visits (p = 0.002). Conclusion Effective treatment that will reduce hospitalizations and the burden of chronic disability in patients with SMI would greatly reduce mental health care cost. Clozapine remains the gold standard in the treatment of refractory schizophrenia. But due to the risk of agranulocytosis, clozapine is underutilized. It was hoped that this study will support the use of clozapine in SMI patients. Disappointingly, the use of clozapine did not prevent relapses and hospitalizations in this patient population and patients on clozapine seemed to have increased hospitalizations, compared to those who were not on clozapine. Perhaps, a different outcome would have occurred if the focus was limited to the patients themselves who were on Clozapine and ascertain what the rate of hospitalization was before the start of clozapine vs after the use of clozapine.

The Use of Long-Acting Injectable Antipsychotics (LAI) in the Serious Mental Illness (SMI) Patients Enrolled in an Assertive Community Treatment (ACT) Program.

Introduction Patients with serious mental illness (SMI) experience highly intractable symptoms and great levels of dysfunction from their mental illness. Relapse prevention is critical as psychopathology, social and occupational functioning worsen with repeated psychotic episodes. Poor medication adherence is a strong predictor of relapse. Use of long-acting injectable antipsychotics (LAI) is among the most effective treatment specially in the context of non-adherence and yet remains underutilized. This single center retrospective study conducted using the electronic medical record (EMR) of patients enrolled in an Assertive Community Treatment (ACT) program at a community hospital was analyzed as to whether use of LAI among these patients reduce the frequency of emergency room visits and hospitalizations. Materials and methods Single center retrospective study using EMR of patients ages 20 and above who were enrolled at the ACT program at a community hospital from December 1, 2008 to December 31, 2018. Variables were collected from the EMR and de-identified into an Excel spreadsheet for data collation. Analysis was performed using SPSS software package. Results A total of 179 patients enrolled in the ACT program and their hospitalizations were extracted from the EMR. Seventy-six (42.5%) of these hospitalizations had patients on LAI. The hospitalizations were made up of 53.6% male, 81.9% White/Asian, 18.1% Black; 44.1% ages between 36 and 50 years old, 30.2% ages between 18 and 35 years old, and 25.7% greater than 50 years old. There was no difference in age, sex, race, ethnicity, insurance type and time spent in ACT program between those using LAI and those not on LAI. There was a higher proportion of psychiatric hospitalizations among LAI users compared with the non-LAI user group (57.9% vs 37.4%, p = 0.007). However, the two groups did not differ from one another in terms of psychiatric emergency visits (p = 0.266) or frequency of ACT visits (p = 0.062). Conclusion To date, all of the new-generation antipsychotic LAI have demonstrated a statistically and clinically significant decrease of relapse rates over placebo. Despite this, LAIs are not widely prescribed for a variety of reasons, including the reservations of patients, clinicians and payers. It would seem, though, that our patient population at the ACT program do not seem to benefit from use of LAI in relapse prevention. These results are counterintuitive in that one would expect that patients with serious mental illness would benefit from use of LAI. Perhaps, individuals with SMI are a different subset of population and they do not respond as well to LAI.

Clinical practice: chimeric antigen receptor (CAR) T cells: a major breakthrough in the battle against cancer.

Chimeric antigen receptor (CAR) T cell therapy has come of age, offering a potentially curative option for patients who are refractory to standard anti-cancer treatments. The success of CAR T cell therapy in the setting of acute lymphoblastic leukemia and specific types of B cell lymphoma led to rapid regulatory approvals of CD19-directed CAR T cells, first in the United States and subsequently across the globe. Despite these major milestones in the field of immuno-oncology, growing experience with CAR T cells has also highlighted the major limitations of this strategy, namely challenges associated with manufacturing a bespoke patient-specific product, intrinsic immune cell defects leading to poor CAR T cell function as well as persistence, and/or tumor cell resistance resulting from loss or modulation of the targeted antigen. In addition, both on- and off-tumor immunotoxicities and the financial burden inherent in conventional cellular biomanufacturing often hamper the success of CAR T cell-based treatment approaches. Herein, we provide an overview of the opportunities and challenges related to the first form of gene transfer therapy to gain commercial approval in the United States. Ongoing advances in the areas of genetic engineering, precision genome editing, toxicity mitigation methods and cell manufacturing will improve the efficacy and safety of CAR T cells for hematologic malignancies and expand the use of this novel class of therapeutics to reach solid tumors.

Tumor lymphangiogenesis predicts melanoma metastasis to sentinel lymph nodes.

Cutaneous melanoma is a common melanocytic neoplasm that can quickly metastasize to regional lymph nodes. Currently, prognosis is determined by measuring tumor thickness but more reliable markers for metastatic spread are urgently needed. We investigated whether the extent of tumor lymphangiogenesis can predict melanoma metastasis to sentinel lymph nodes. We quantified the extent of tumor lymphangiogenesis, as well as other factors, in excised primary tumors and in sentinel lymph node biopsy samples from 45 patients with primary cutaneous melanoma. The results were correlated with histological and clinical outcome. Primary melanomas from patients whose tumors had metastasized to the sentinel lymph nodes contained prominent 'hot spots' of increased lymphatic vessel density, compared to nonmetastatic tumors. Multivariate risk analysis revealed that the lymphatic vascular area of primary melanomas, an index of tumor lymphangiogenesis, was the most sensitive prognostic marker for sentinel lymph node metastasis, and was even able to more accurately predict which tumors were metastatic to sentinel lymph nodes than the currently used method of measuring tumor thickness. Highly lymphangiogenic melanomas maintained their lymphangiogenic activity after metastasis to the sentinel lymph node. The extent of tumor lymphangiogenesis is a highly sensitive (83%) and specific (89%) prognostic marker of lymph node metastasis. Assessment of lymphangiogenesis in primary melanomas may be a more effective approach than the currently used technique of measuring tumor thickness in selecting patients with early metastatic disease for aggressive therapy.
