Non-literacy biased, culturally fair cognitive detection tool in primary care patients with cognitive concerns: a randomized controlled trial.

Dementia is often undiagnosed in primary care, and even when diagnosed, untreated. The 5-Cog paradigm, a brief, culturally adept, cognitive detection tool paired with a clinical decision support may reduce barriers to improving dementia diagnosis and care. We performed a randomized controlled trial in primary care patients experiencing health disparities (racial/ethnic minorities and socioeconomically disadvantaged). Older adults with cognitive concerns were assigned in a 1:1 ratio to the 5-Cog paradigm or control. Primary outcome was improved dementia care actions defined as any of the following endpoints within 90 days: new mild cognitive impairment syndrome or dementia diagnoses as well as investigations, medications or specialist referrals ordered for cognitive indications. Groups were compared using intention-to-treat principles with multivariable logistic regression. Overall, 1,201 patients (mean age 72.8 years, 72% women and 94% Black, Hispanic or Latino) were enrolled and 599 were assigned to 5-Cog and 602 to the control. The 5-Cog paradigm demonstrated threefold odds of improvement in dementia care actions over control (odds ratio 3.43, 95% confidence interval 2.32-5.07). No serious intervention-related adverse events were reported. The 5-Cog paradigm improved diagnosis and management in patients with cognitive concerns and provides evidence to promote practice change to improve dementia care actions in primary care.ClinicalTrials.gov: NCT03816644 .

ASTHMAXcel PRO patient satisfaction and usability field testing.

Background: ASTHMAXcel PRO, an enhanced version of the ASTHMAXcel mobile application, has been developed to deliver comprehensive, guideline-based asthma education while also facilitating the collection of patient-reported outcomes (PROs) and enhancing user experience.Objective: To perform field testing and conduct formative and summative evaluation of the ASTHMAXcel PRO application to assess its impact on patient satisfaction, usability, and usage.Methods: Twenty-eight adult patients completed a baseline visit during which ASTHMAXcel PRO was introduced, health literacy was assessed, and demographic data were collected. They were instructed to use the app for 4 weeks. The Questionnaire for User Interface Satisfaction (QUIS) and the Unified Theory of Acceptance and Use of Technology (UTAUT) questionnaire were administered at baseline and 4 weeks to assess user satisfaction and technology acceptance, respectively. Semi-structured interviews were conducted to gather feedback regarding the application from patients.Results: The baseline total scores were high for both UTAUT and QUIS (mean (SD): 64.2 (10.1), 6.8 (2.2) respectively) indicating that user satisfaction and acceptance began at high levels. UTAUT total score, as well as all domain scores, improved significantly from baseline to 4 weeks (p < 0.02). QUIS total score along with several domain scores (screen, system capabilities, usability) also increased from baseline to 4-weeks (p = 0.03, 0.01, 0.03, 0.01, respectively). These improvements remained significant when adjusting for age, gender, education, and health literacy. Patients reported that the application was helpful, informative, and easy to understand and use.Conclusion: The significant increases in satisfaction and technology adoption observed among ASTHMAXcel PRO users demonstrate that the application is viable and has the potential to improve upon usability challenges faced by existing mobile health applications.

An Observational Study Comparing Hybrid Transvaginal Notes and Four-Port Laparoscopic Cholecystectomy.

BACKGROUND: Recently, a great interest has arisen in hybrid natural orifice transluminal endoscopic surgery-cholecystectomy (NOTES-C). It has the potential to cause less postoperative pain and may offer better cosmesis over conventional laparoscopic cholecystectomy (CLC). PATIENTS AND METHODS: A total of 112 females who underwent conventional cholecystectomy were compared with 108 patients of hybrid transvaginal NOTES-cholecystectomy (TV NOTES-C). We compared intraoperative factors, postoperative pain, the analgesic requirement at different intervals, duration of hospital stay, and time to return to normal activities. In addition, cosmesis and patient satisfaction were assessed at four weeks. RESULTS: Postoperative pain and analgesic requirement were less in the hybrid TV NOTES-C group (p<0.001 at 95% CI). Hybrid TV NOTES-C patients were discharged more frequently within 12 hours (27.5% versus 1.8%; p<0.001) and returned faster (2.22 versus 4.62 days; p<0.001) to normal activities. Cosmetic results and short-term quality of life as assessed by the patient and observer scar assessment scale (POSAS) and short form-36 (SF-36) scores, respectively, were better in the hybrid TV NOTES-C group (p<0.001 at 95% CI). CONCLUSIONS: Hybrid TV NOTES-C is associated with reduced postoperative analgesic requirements, faster return to normal activities, better cosmesis, and patient satisfaction compared to conventional four-port cholecystectomy.

The 5-Cog paradigm to improve detection of cognitive impairment and dementia: clinical trial protocol.

Cognitive impairment related to dementia is under-diagnosed in primary care despite availability of numerous cognitive assessment tools; under-diagnosis is more prevalent for members of racial and ethnic minority groups. Clinical decision-support systems may improve rates of primary care providers responding to positive cognitive assessments with appropriate follow-up. The 5-Cog study is a randomized controlled trial in 1200 predominantly Black and Hispanic older adults from an urban underserved community who are presenting to primary care with cognitive concerns. The study will validate a novel 5-minute cognitive assessment coupled with an electronic medical record-embedded decision tree to overcome the barriers of current cognitive assessment paradigms in primary care and facilitate improved dementia care.

Dementia is common, though under-recognized, in older adults (OAs). Primary care providers (PCPs) miss opportunities to help patients and their families manage the disease because of failure to, or delay to, make an appropriate diagnosis. Black and Hispanic OAs are more likely than White OAs to experience delayed diagnosis. Most available memory tests are too long for practical use by PCPs, and are ill suited to patients of diverse language, cultural and educational backgrounds. Studies have shown that even when patients test positive for dementia in primary care, PCPs often do not take follow-up action. Our improved memory test, the 5-Cog, is brief (5 min), not biased by language issues (uses pictures and symbols instead of words), and simple (doesn't require expensive technology and complex staff training). The 5-Cog is paired with a clinical decision support tool, providing tailored recommendations directly into the patient's medical record, and making it easier for PCPs to take appropriate action. This study will evaluate whether the 5-Cog paradigm results in improved dementia care.

Lessons from Detecting Cognitive Impairment Including Dementia (DetectCID) in Primary Care.

BACKGROUND: Cognitive impairment, including dementia, is frequently under-detected in primary care. The Consortium for Detecting Cognitive Impairment, including Dementia (DetectCID) convenes three multidisciplinary teams that are testing novel paradigms to improve the frequency and quality of patient evaluations for detecting cognitive impairment in primary care and appropriate follow-up. OBJECTIVE: Our objective was to characterize the three paradigms, including similarities and differences, and to identify common key lessons from implementation. METHODS: A qualitative evaluation study with dementia specialists who were implementing the detection paradigms. Data was analyzed using content analysis. RESULTS: We identified core components of each paradigm. Key lessons emphasized the importance of engaging primary care teams, enabling primary care providers to diagnose cognitive disorders and provide ongoing care support, integrating with the electronic health record, and ensuring that paradigms address the needs of diverse populations. CONCLUSION: Approaches are needed that address the arc of care from identifying a concern to post-diagnostic management, are efficient and adaptable to primary care workflows, and address a diverse aging population. Our work highlights approaches to partnering with primary care that could be useful across specialties and paves the way for developing future paradigms that improve differential diagnosis of symptomatic cognitive impairment, identifying not only its presence but also its specific syndrome or etiology.

Collaborative Care for Low-Income Patients From Racial-Ethnic Minority Groups in Primary Care: Engagement and Clinical Outcomes.

OBJECTIVE: To assess model impact and opportunities for improvement, this study examined collaborative care model (CoCM) engagement and clinical outcomes among low-income patients from racial-ethnic minority groups with depression and anxiety. METHODS: Starting in 2015, the CoCM was implemented in seven primary care practices of an urban academic medical center serving patients from racial-ethnic minority backgrounds, predominantly Medicaid beneficiaries. Eligible individuals scored positive for depressive or anxiety symptoms (or both) on the Patient Health Questionnaire-2 (PHQ-2) and PHQ-9 and the Generalized Anxiety Disorder Scale-2 (GAD-2) and GAD-7 during systematic screening in primary care settings. Screening rates and yield, patient characteristics, and CoCM engagement and outcomes were examined. Clinical improvement was measured by the difference in PHQ-9 and GAD-7 scores at baseline and at 10-to-14-week follow-up. RESULTS: High rates of screening (87%, N=88,236 of 101,091) and identification of individuals with depression or anxiety (13%, N=11,886) were observed, and 58% of 3,957 patients who engaged in minimally adequate CoCM treatment had significant clinical improvement. Nevertheless, only 56% of eligible patients engaged in the model, and 25% of those individuals did not return for at least one follow-up appointment. Being female with clinically significant comorbid anxiety and depressive symptoms and having Medicaid or commercial insurance increased the likelihood of CoCM engagement. CONCLUSIONS: CoCM can help engage vulnerable patients in behavioral health care and improve clinical symptoms. However, significant opportunity exists to advance the model's impact in treating depressive and anxiety disorders and decreasing health disparities by addressing engagement barriers.

Subacute duodenal obstruction caused by Common Celiaco-Mesenteric Trunk anomaly-A case report.

INTRODUCTION AND IMPORTANCE: The origin of the mesenteric vasculature is highly variable. One such variation is the common celiaco-mesenteric trunk (CMT). To our knowledge, this is the first reported case of subacute duodenal obstruction caused by common CMT. The awareness of this anomaly helps keep a high index of suspicion for varied presentations, prompts appropriate investigations, timely intervention, and avoids iatrogenic injury. PATIENT PROFILE: A 15-year-old boy presented with a history of repeated attacks of colicky abdominal pain with bilious vomiting. Computed tomography of the abdomen with intravenous contrast revealed subacute duodenal obstruction caused by an acute angulation of common CMT with the abdominal aorta. To relieve the obstruction, the patient underwent a side-to-side duodenojejunostomy. DISCUSSION: A common CMT, where the coeliac artery (CA) and superior mesenteric artery (SMA) have a common origin from the aorta, accounts for less than 1% of all splanchnic artery anomalies. Most CMTs are incidental findings, but aneurysm or dissection of the common trunk commonly accompany this anatomical aberrancy. Intestinal obstruction due to CMT anomaly is a rare occurrence. CONCLUSION: There should be a high index of suspicion concerning vascular anomalies in patients, especially children presenting with repeated episodes of subacute intestinal obstruction. This knowledge of vascular aberrations prevents disastrous iatrogenic complications.

Hydralazine-associated antineutrophil cytoplasmic antibody vasculitis with pulmonary-renal syndrome.

Hydralazine, a vasodilator, is commonly used as an adjunctive treatment for moderate to severe hypertension, heart failure and hypertensive emergencies in pregnancy. Hydralazine-induced lupus was first described in 1953. Clinical presentation ranges from arthralgia, myalgia, petechiae, or rash to single or multiorgan involvement. An occurrence of systemic vasculitis is a rare complication. When presented as the pulmonary-renal syndrome, it could have a rapidly progressive course which can be fatal. Here, we describe a case of hydralazine-associated rapidly progressive glomerulonephritis and pulmonary haemorrhage. We use this case to review the current literature and discuss and highlight the importance of a high degree of clinical acumen, early diagnosis and prompt treatment for better clinical outcomes.

Rare Case of Intracardiac Renal Cell Carcinoma Metastasis with Response to Nivolumab: Case Report and Literature Review.

Intracardiac metastases in the absence of inferior vena cava involvement is a rare occurrence in patients with metastatic renal cell carcinoma (mRCC). There is limited evidence regarding the efficacy and safety of standard treatment modalities for mRCC patients with intracardiac metastases. Presence of intracardiac metastases is known to indicate poor prognosis and may potentially increase risk of treatment-related complications. Recent advances in RCC management have integrated nivolumab, a programmed death-1 (PD-1) receptor inhibitor, as a preferred treatment option in the second-line setting after failure of prior anti-angiogenic therapy; or in combination with ipilimumab, an anti-Cytotoxic T-lymphocyte antigen-4 antibody as first-line therapy for intermediate to poor risk patients with mRCC. The efficacy and toxicity of nivolumab in patients with mRCC and intracardiac metastases has never been reported previously. We herein present the first reported case of mRCC with intracardiac metastasis and a resultant excellent response to nivolumab treatment and discuss the imaging techniques and treatment options for this rare presentation.

Value of surgery for infective endocarditis in dialysis patients.

OBJECTIVES: To determine the value of surgery for infective endocarditis (IE) in patients on hemodialysis by comparing the nature and invasiveness of endocarditis in hemodialysis and nonhemodialysis patients and their hospital and long-term outcomes, and identifying risk factors for time-related mortality after surgery. METHODS: From January 1997 to January 2013, 144 patients on chronic hemodialysis and 1233 nonhemodialysis patients underwent valve surgery for IE at our institution. Propensity matching identified 99 well-matched hemodialysis and nonhemodialysis patient pairs for comparison of outcomes. RESULTS: Staphylococcus aureus infection was more common in hemodialysis patients than in nonhemodialysis patients (42% vs 21%; P < .0001), but invasive disease was similar in the 2 groups (47%; P = .3). Hospital mortality was 13% and 5-year survival was 20% for hemodialysis patients, 20% below that expected in a general hemodialysis population but 15% above that of hemodialysis patients treated nonsurgically for IE. For matched patients, hospital mortality was 13% for hemodialysis patients versus 5.1% for nonhemodialysis patients (P = .05), and survival at 1 and 5 years was 56% versus 83% and 24% versus 59%, respectively (P < .004). Use of an arteriovenous graft for dialysis access (P = .01) and preoperative placement of a pacemaker (P < .0001) were risk factors for late mortality in hemodialysis patients. For matched patients, freedom from reoperation was similar in the hemodialysis and nonhemodialysis groups (P > .9). CONCLUSIONS: Intermediate-term survival after surgery for IE in hemodialysis patients is substantially worse than that in nonhemodialysis patients, but only slightly worse than that in the general hemodialysis population and substantially better than that in hemodialysis patients with IE treated nonsurgically, supporting continued surgical intervention for IE.

A Rare Case of Hematuria; Primary Amyloidosis of the Bladder Neck.

Primary and localized amyloidosis of the urinary tract is considered to be a rare clinical entity with approximately 160 cases documented in the literature. Here we present a case of a 77 year old gentleman with painless visible hematuria. Flexible cystoscopy revealed abnormal and polypoidal bladder mucosa. Transurethral resection of these lesions revealed histology with congo-red staining and positive green-apple birefringence, these findings are consistent with amyloidosis. There has so far been no sign of recurrence in this gentleman, with routine cystoscopic surveillance. Here we present a literature review on the presentation, diagnosis and management of this rare condition.

Critical appraisal of axitinib in the treatment of advanced renal cell carcinoma.

A growing understanding of the biology of renal cell carcinoma (RCC) has led to the development and US Food and Drug Administration approval of seven new molecular targeted agents over the past 7 years. Axitinib is a potent, selective, second-generation inhibitor of vascular endothelial growth factor receptors and the latest to join the armamentarium of drugs available for the treatment of metastatic RCC. Despite recent advances in the development of molecular targeted agents for metastatic RCC, the ideal sequencing of these agents remains unclear.

CUL3 and NRF2 mutations confer an NRF2 activation phenotype in a sporadic form of papillary renal cell carcinoma.

Sustained activation of the stress-regulated transcription factor NRF2 (NFE2L2) is a prominent feature of many types of cancer, implying that mutations driving NRF2 may be important to tumor progression. In hereditary type 2 papillary renal cell carcinoma (PRCC2, also known as hereditary leiomyomatosis and renal cell cancer), NRF2 activation is a direct consequence of the accumulation of intracellular fumarate, a result of fumarate hydratase (FH) inactivation, but it is not clear how NRF2 may be activated in sporadic forms of PRCC2. Here we show that somatic mutations in NRF2, CUL3, and SIRT1 are responsible for driving the NRF2 activation phenotype in sporadic PRCC2. Transcriptome sequencing revealed the expression pattern of mutant alleles of NRF2, CUL3, and SIRT1 and also confirmed NRF2 activation in clinical specimens. Our results show a convergence in somatic mutations in sporadic PRCC2 with FH mutation in hereditary PRCC2.

Cardioprotective activity of chalcones in ischemia/reperfusion-induced myocardial infarction in albino rats.

BACKGROUND: There is a comprehensive body of experimental and clinical evidence suggesting that exogenous supplementation of natural antioxidants or augmentation of endogenous antioxidants attenuates the damage caused by myocardial infarction. OBJECTIVE: To evaluate the cardioprotective effects of Cl-chalcone and F-chalcone against ischemia/reperfusion (I/R)-induced myocardial infarction in rats. METHODS: Myocardial infarct size was measured using the staining agent 2,3,5-triphenyltetrazolium chloride. Malondialdehyde was measured in serum and heart tissue, and superoxide dismutase and catalase in heart tissue were measured spectrophotometrically. RESULTS: I/R resulted in significant cardiac necrosis, indicated by a rise in the end products of myocardial lipid peroxidation (malondialdehydes). A loss of antioxidative enzymes (superoxide dismutase and catalase) in heart tissue was also observed in animals subjected to in vivo myocardial I/R injury. DISCUSSION: The present study demonstrated that treatment with Cl-chalcone and F-chalcone significantly limited infarct size, partially but significantly attenuated the level of lipid peroxidation and moderated the loss of antioxidant reserves in rats subjected to 30 min coronary artery occlusion followed by a 4 h reperfusion in comparison with I/R groups. CONCLUSIONS: The results of the present study suggest that chalcones have cardioprotective activity against I/R-induced myocardial infarction in rats.

Therapeutic roles of heparin anticoagulants in cancer and related disorders.

Cancer represents a major cause of overall mortality, second to cardiovascular disorders. Cancer patients frequently encounter hypercoagulable states, with recurrent thromboembolic events due to the impact of cancer cells and chemotherapy/radiotherapy on the coagulation cascade. The expression of highly procoagulant proteins have been implicated to involve in tumor cell-induced thrombin generation, leading to platelet activation and fibrin clot formation. These include binding of heparin to angiogenic growth factors (e.g., basic fibroblast growth factor and vascular endothelial growth factor); modulation of tissue factor (TF); and enhanced TF-pathway-inhibitor release, and inhibition of matrix-degrading enzymes. The classical anticoagulant (unfractionated heparin; UFH), and its derived low-molecular-weight heparins (LMWH) are polypharmacologic agents. These anticoagulants are composed of oligosccharides with structural/molecular heterogeneity. Heparins bind to wide range of molecules via electrostatic interactions with the glycosaminoglycan chains, and hence possess numerous therapeutic properties beyond their anticoagulant effects, including anti-cancer potentials. Recent studies demonstrate that UFH and LMWH fractions interfere with various cellular/inflammatory processes and reduce mortality/morbidity in malignancy-associated thrombosis and vascular disorders. There are certain weaknesses of heparins, particularly when patients receiving prolonged therapy, including bleeding complications. Paradoxically, many individuals receiving heparin anticoagulants develop antibodies against the complex formed between heparin and platelet factor 4 because of massive platelet/cellular activation and hypercoagulable state, resulting in clinical manifestation referred to as heparin-induced thrombocytopenia (HIT) syndrome. Increased risk of venous thromboembolic events are likely in individuals with malignancy-associated thrombosis coupled with underlying HIT pathogenesis. This article will review the existing knowledge about the experimental/clinical anti-cancer properties of heparin anticoagulants and provide a rationale for future research.

Role of second-line systemic treatment post-docetaxel in metastatic castrate resistant prostate cancer- current strategies and future directions.

Treatment of metastatic castrate resistant prostate cancer (mCRPC) after progression on docetaxel chemotherapy is a challenging clinical scenario with limited availability of treatment options. Re-treatment with docetaxel, either as monotherapy or in combination with other cytotoxics or targeted agents has shown durable responses. However, most docetaxel re-treatment studies have been either retrospective or early phase non-randomised studies which have not formally assessed Quality of life or survival gain with re-treatment. Despite limited evidence for efficacy of mitoxantrone in the second-line, it continues to remain widely used, largely due to lack of available suitable alternatives. Cabazitaxel in combination with prednisolone is the only chemotherapy to have shown a significant survival benefit and receive approval by the U.S. Food and Drug Administration for patients with mCRPC previously treated with a docetaxel-based regimen. Abiraterone acetate has recently demonstrated a significant improvement in survival when compared to placebo in patients with docetaxel-treated mCRPC. This review aims to summarize the current evidence and discuss future strategies for treatment of mCRPC patients following failure of docetaxel chemotherapy.

An unusual case of swelling--Clarkson's syndrome.

Clarkson's syndrome, also called idiopathic systemic capillary leak syndrome is a rare condition characterised by vascular hyper permeability resulting in extreme intravascular volume depletion. The syndrome is unique and almost paradoxical in its presentation, with findings initially suggesting overwhelming heart failure, but in reality the extra vascular fluid represents overt capillary leak, with ultimate intravascular volume depletion, a low output state and hypovolemic shock. Previously described characteristics have classically included severe oedema and anasarca with rapid, profound shock, typically accompanied by haemoconcentration. The authors describe a patient, initially seeming benign in presentation, who rapidly progressed with confusing findings of fluid overload by examination and imaging, ultimately manifesting these findings by severe capillary leak rather than hydrostatic oedema, with ultimate hypovolaemic shock, multisystem organ failure and death. Our aim is that by describing clinical, haemodynamic and pathologic descriptors of the disease, the authors can aid in increasing physician awareness of this unusual syndrome.

Traumatic aortic injury: a case report.

Trauma is the leading cause of death under the age of 35 years worldwide. Traumatic aortic rupture is responsible for 18% of all road accident mortality. Eighty percent of these patients die at the scene of the accident. Of the survivors, 50% die within 24 hours if left untreated. Rapid transport and resuscitation, awareness of the injury, availability of multi-slice computed tomography (MSCT), and timely intervention can significantly improve survival in aortic injury.

Success and complications of endoscopic removal of giant duodenal and ampullary polyps: a comparative series.

BACKGROUND: Increasing reports suggest that endoscopic removal of benign ampullary and duodenal polyps is safe and frequently definitive; however, most reported polyps have been small in size (<3 cm). We have developed experience with endoscopic removal of increasingly large and complex polyps. PATIENTS: Fifty-one cases of endoscopic removal were attempted and grouped according to size: group A (n = 22) polyps 1 to 3 cm and group B (n = 29) polyps 3 cm or larger, including 7 cases larger than 5 cm. When the ampulla was involved, biductal sphincterotomy and prophylactic pancreatic duct stent placement was performed first, followed by saline solution-assisted piecemeal polypectomy, argon plasma coagulation, selective endoclip placement, and recovery of all polyp fragments. INTERVENTIONS: Endoscopic removal of duodenal and ampullary adenomas. RESULTS: The outcomes of small and large adenoma removal include mean number of endoscopic retrograde cholangiopancreatographies required for complete removal (2.09 vs 2.56, P = .392), number of complications (4.5% vs 13.9%, P = .375), discovery of unsuspected cancer (0% vs 10.3%, P = .242), and final definitive resolution (100% vs 86.2%, P = .124). Complete removal was achieved in 92.2% of all patients. LIMITATIONS: This was a single center retrospective study. CONCLUSIONS: Large (>/=3 cm) ampullary and duodenal polyps comprised 56.9% of our endoscopically treated cases and present special challenges to definitive endoscopic removal. Successful removal of even very large sessile lesions is possible with minimal increase in risk.

Marginal PM25: Nonlinear Aerosol Mass Response to Sulfate Reductions in the Eastern United States.

Reductions in airborne sulfate concentration may cause inorganic fine particulate matter (PM25) to respond nonlinearly, as nitric acid gas may transfer to the aerosol phase. Where this occurs, reductions in sulfur dioxide (SO2) emissions will be much less effective than expected at reducing PM2.5. As a measure of the efficacy of reductions in sulfate concentration on PM , we define marginal PM2.5 as the local change in PM2.5 resulting from a small change in sulfate concentration. Using seasonal-average conditions and assuming thermodynamic equilibrium, we find that the conditions for PM2.5 to respond nonlinearly to sulfate reductions are common in the eastern United States in winter, occurring at half of the sites considered, and uncommon in summer, due primarily to the influence of temperature. Accounting for diurnal and intraseasonal variability, we find that seasonal-average conditions provide a reasonable indicator of the time-averaged PM2.5 response. These results indicate that reductions in sulfate concentration may be up to 50% less effective at reducing the annual-average PM2.5 than if the role of nitric acid is neglected. Further, large reductions in sulfate will also cause an increase in aerosol nitrate in many regions that are the most acidic.
