Abstract
Inflammatory bowel diseases (IBDs) consist of a group of chronic inflammatory disorders with a complex etiology, which represent a clinical challenge due to their often therapy-refractory nature. In IBD, inflammation of the intestinal mucosa is characterized by strong and sustained leukocyte infiltration, resulting in the loss of epithelial barrier function and subsequent tissue destruction. This is accompanied by the activation and the massive remodeling of mucosal micro-vessels. The role of the gut vasculature in the induction and perpetuation of mucosal inflammation is receiving increasing recognition. While the vascular barrier is considered to offer protection against bacterial translocation and sepsis after the breakdown of the epithelial barrier, endothelium activation and angiogenesis are thought to promote inflammation. The present review examines the respective pathological contributions of the different phenotypical changes observed in the microvascular endothelium during IBD, and provides an overview of potential vessel-specific targeted therapy options for the treatment of IBD.

Abstract
Vasculitides can present with various clinical signs and symptoms. Besides disease-specific organ manifestations, the skin, peripheral nerves and musculature are frequently involved. The combination of elevated serological inflammatory markers, vasculitic skin lesions, active polyneuropathy and immobilizing myalgia of the lower limb musculature is highly suspicious for muscular polyarteritis nodosa (mPAN). Based on the case of a 63-year-old female patient with a vasculitic syndrome confined to the lower limb due to mPAN, important differential diagnoses of the these disease manifestations are discussed. Magnetic resonance imaging of the affected muscles and subsequent muscle biopsy (including skin and fascia) provide the relevant diagnostic data.

Abstract
BACKGROUND The anti-SOX-1 antibodies have been mainly associated with Lambert-Eaton Myasthenic Syndrome (LETMS) and Small-Cell Lung Cancer (SCLC). In this report, we describe the interesting case of a patient with serum anti-SOX-1 antibodies and Crohn's Disease (CD) with ensuing neurological symptoms. CASE PRESENTATION A Caucasian 67-year-old female was admitted to the Emergency Department with seizures, vertigo, emesis, nausea, postural instability and recurrent falls, over a period of 10 days. She had been affected by Crohn's Disease since 1991. A CT scan failed to detect any ischemic or haemorrhagic lesion. A brain MRI revealed signs of leukoencephalopathy. Western blot analysis of her serum revealed a high titre of the onconeural antibody anti-SOX1, consistent with a neurological, cerebellar type, paraneoplastic syndrome. In spite of multiple efforts to unmask a possible underlying malignancy, no neoplastic lesion cropped up during hospitalization. Her clinical conditions progressively deteriorated, up to respiratory failure; a few days later she died, due to ensuing septic shock and Multiple Organ Failure. CONCLUSIONS Our experience may usher and reveal a new role of anti-neural antibodies, so far reckoned an early indicator of associated malignancy, suggesting that neurological syndromes associated with such antibodies may complicate also chronic Gastrointestinal (GI) diseases. As of now, testing for anti-neuronal antibodies appeared unnecessary within the diagnostic assessment of gastroenterological disorders, which may lead to overlooking incident neurologic autoimmune diseases. Further exploration of such research hypothesis in clinical grounds appears intriguing.

Abstract
Background Guillain–Barré Syndrome is an immune mediated polyneuropathy. Ulcerative Colitis is an immune mediated chronic inflammatory condition mainly of the large intestine. Guillain–Barré Syndrome can present as a rare extraintestinal manifestation of Ulcerative Colitis when in remission or in a relapse. However, the concomitant presentation of Guillain–Barré Syndrome during a relapse of Ulcerative Colitis is very rare and only a few cases are reported to date. Case presentation A 24 year old young male diagnosed of Ulcerative Colitis presented with bloody diarrhea of frequency more than six times a day. He had been in clinical remission even after defaulting treatment for more than a year. He had also noted difficulty in walking prior to admission to the hospital. He was managed as for a severe relapse of Ulcerative Colitis and Guillain–Barré Syndrome. Appropriate management of both the illnesses helped him to recover. Conclusion Immune mediated diseases can have rare coexisting presentations. We report a case of Ulcerative Colitis with concomitant Guillain–Barré Syndrome. It is essential to be open minded and timely, appropriate treatment led to successful management of both the illnesses.

Abstract
Simple Summary Immune-mediated inflammatory diseases (IMIDs) are growing in prevalence and relevance in our society, entailing notable consequences for the individual and healthcare systems. These medical conditions are associated with a systemic inflammatory milieu and an aberrant functioning of the immune system, establishing a bidirectional interplay with other organs and systems of the body. Psychoneuroimmunoendocrinology (PNIE) is an area of great interest relating the immune system with the individual’s psyche, nervous, and endocrine system. As compelling evidence supports the pivotal role of PNIE in the understanding and clinical management of IMIDs, the aim of the present review is to deepen the current basic and clinical knowledge in this field. Abstract Immune-mediated inflammatory diseases (IMIDs) represent a large group of diseases (Crohn’s, ulcerative colitis, psoriasis, lupus, and rheumatoid arthritis) evidenced by systemic inflammation and multiorgan involvement. IMIDs result in a reduced quality of life and an economic burden for individuals, health care systems, and countries. In this brief descriptive review, we will focus on some of the common biological pathways of these diseases from the point of view of psychoneuroimmunoendocrinology (PNIE). PNIE consists of four medical disciplines (psychology, nervous system, immune system, and endocrine system), which are key drivers behind the health–disease concept that a human being functions as a unit. We examine these drivers and emphasize the need for integrative treatments that addresses the disease from a psychosomatic point of view.

Abstract
OBJECTIVES Mounting evidence points to the microbiome as a susceptibility factor for neurological disorders. Patients with Crohn's disease (CD) are at higher ischemic stroke (IS) risk, but no large scale epidemiologic studies have identified risk factors for stroke in this population. MATERIALS AND METHODS We analyzed the 2017 Nationwide Inpatient Sample (NIS) dataset to identify patients with a discharge diagnosis of Crohn's disease using the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) code K50.X. We identified patients with a primary/secondary discharge diagnosis of IS using ICD-10-CM code I63.X. We compared sociodemographic and clinical variables between stroke and non-stroke patients with CD. Logistic regression analysis was applied to identify factors associated with IS. RESULTS Of 30,212 patients with CD, 369 (1.2 %) had a discharge diagnosis of IS. Older age (odds ratio [OR], 1.03 [95% CI, 1.02-1.04], top quartile income (OR, 1.58 [95% CI, 1.10-2.30]), and hospitalization in a South Atlantic (OR, 1.82 [95% CI, 1.11-3.14]), East South Central (OR, 2.30 [95% CI, 1.28-4.25]), or West South Central hospital (OR, 2.40 [95% CI, 1.39-4.28]) were independently associated with IS. Clinical variables independently associated with IS in patients with CD included: atrial fibrillation (OR, 1.66 [95% CI, 1.15-2.33]), atherosclerosis (OR, 2.41 [95% CI, 1.32-4.10]), hyperlipidemia (OR, 1.69 [95% CI, 1.33-2.15]), hypertension (OR, 1.53 [95% CI, 1.18-1.98]) and valvular disease (OR, 1.62 [95% CI, 1.01-2.48). CONCLUSION A subset of traditional stroke risk factors are associated with IS in patients with CD. CD patients with these conditions could be targeted for vascular risk reduction and surveillance.

Abstract
Traumatic brain injury (TBI) is a chronic and progressive disease, and management requires an understanding of both the primary neurological injury and the secondary sequelae that affect peripheral organs, including the gastrointestinal (GI) tract. The brain-gut axis is composed of bidirectional pathways through which TBI-induced neuroinflammation and neurodegeneration impact gut function. The resulting TBI-induced dysautonomia and systemic inflammation contribute to the secondary GI events, including dysmotility and increased mucosal permeability. These effects shape, and are shaped by, changes in microbiota composition and activation of resident and recruited immune cells. Microbial products and immune cell mediators in turn modulate brain-gut activity. Importantly, secondary enteric inflammatory challenges prolong systemic inflammation and worsen TBI-induced neuropathology and neurobehavioral deficits. The importance of brain-gut communication in maintaining GI homeostasis highlights it as a viable therapeutic target for TBI. Currently, treatments directed toward dysautonomia, dysbiosis, and/or systemic inflammation offer the most promise.

Abstract
BACKGROUND Disruptions of brain-gut axis have been implicated in the progression of a variety of gastrointestinal (GI) disorders and central nervous system (CNS) diseases and injuries, including traumatic brain injury (TBI). TBI is a chronic disease process characterized by persistent secondary injury processes which can be exacerbated by subsequent challenges. Enteric pathogen infection during chronic TBI worsened cortical lesion volume; however, the pathophysiological mechanisms underlying the damaging effects of enteric challenge during chronic TBI remain unknown. This preclinical study examined the effect of intestinal inflammation during chronic TBI on associated neurobehavioral and neuropathological outcomes, systemic inflammation, and dysautonomia. METHODS Dextran sodium sulfate (DSS) was administered to adult male C57BL/6NCrl mice 28 days following craniotomy (Sham) or TBI for 7 days to induce intestinal inflammation, followed by a return to normal drinking water for an additional 7 to 28 days for recovery; uninjured animals (Naïve) served as an additional control group. Behavioral testing was carried out prior to, during, and following DSS administration to assess changes in motor and cognitive function, social behavior, and mood. Electrocardiography was performed to examine autonomic balance. Brains were collected for histological and molecular analyses of injury lesion, neurodegeneration, and neuroinflammation. Blood, colons, spleens, mesenteric lymph nodes (mLNs), and thymus were collected for morphometric analyses and/or immune characterization by flow cytometry. RESULTS Intestinal inflammation 28 days after craniotomy or TBI persistently induced, or exacerbated, respectively, deficits in fine motor coordination, cognition, social behavior, and anxiety-like behavior. Behavioral changes were associated with an induction, or exacerbation, of hippocampal neuronal cell loss and microglial activation in Sham and TBI mice administered DSS, respectively. Acute DSS administration resulted in a sustained systemic immune response with increases in myeloid cells in blood and spleen, as well as myeloid cells and lymphocytes in mesenteric lymph nodes. Dysautonomia was also induced in Sham and TBI mice administered DSS, with increased sympathetic tone beginning during DSS administration and persisting through the first recovery week. CONCLUSION Intestinal inflammation during chronic experimental TBI causes a sustained systemic immune response and altered autonomic balance that are associated with microglial activation, increased neurodegeneration, and persistent neurological deficits.

Abstract
Xenobiotic nuclear receptors (NR) are intracellular players involved in an increasing number of physiological processes. Examined and characterized in peripheral organs where they govern metabolic, transport and detoxification mechanisms, accumulating data suggest a functional expression of specific NR at the neurovascular unit (NVU). Here, we focus on the Constitutive Androstane Receptor (CAR), expressed in detoxifying organs such as the liver, intestines and kidneys. By direct and indirect activation, CAR is implicated in hepatic detoxification of xenobiotics, environmental contaminants, and endogenous molecules (bilirubin, bile acids). Importantly, CAR participates in physiological stress adaptation responses, hormonal and energy homeostasis due to glucose and lipid sensing. We next analyze the emerging evidence supporting a role of CAR in NVU cells including the blood-brain barrier (BBB), a key vascular interface regulating communications between the brain and the periphery. We address the emerging concept of how CAR may regulate specific P450 cytochromes at the NVU and the associated relevance to brain diseases. A clear understanding of how CAR engages during pathological conditions could enable new mechanistic, and perhaps pharmacological, entry-points within a peripheral-brain axis.

Abstract
Cerebral vasculitis may be a complication of Crohn’s disease (CD) or a side-effect of therapies with biologics including tumor-necrosis factor-alpha antibodies. Here, we report a case of progressive brainstem syndrome and cranial polyneuritis in a patient with CD who had been treated with infliximab. We identified Lyme neuroborreliosis (LNB) as the cause of cerebral vasculitis and ischemic stroke and observed a favorable course following antibiotic treatment. Our case highlights the need for extensive search of causes of cerebral vasculitis in patients with CD and treatment with biologics.

Abstract
Biological barriers are essential for the maintenance of homeostasis in health and disease. Breakdown of the intestinal barrier is an essential aspect of the pathophysiology of gastrointestinal inflammatory diseases, such as inflammatory bowel disease. A wealth of recent studies has shown that the intestinal microbiome, part of the brain-gut axis, could play a role in the pathophysiology of multiple sclerosis. However, an essential component of this axis, the intestinal barrier, has received much less attention. In this review, we describe the intestinal barrier as the physical and functional zone of interaction between the luminal microbiome and the host. Besides its essential role in the regulation of homeostatic processes, the intestinal barrier contains the gut mucosal immune system, a guardian of the integrity of the intestinal tract and the whole organism. Gastrointestinal disorders with intestinal barrier breakdown show evidence of CNS demyelination, and content of the intestinal microbiome entering into the circulation can impact the functions of CNS microglia. We highlight currently available studies suggesting that there is intestinal barrier dysfunction in multiple sclerosis. Finally, we address the mechanisms by which commonly used disease-modifying drugs in multiple sclerosis could alter the intestinal barrier and the microbiome, and we discuss the potential of barrier-stabilizing strategies, including probiotics and stabilization of tight junctions, as novel therapeutic avenues in multiple sclerosis.

Abstract
Ischemic stroke is one of the most common diseases leading to death and is the primary cause of physical handicap. Recent studies have reported that chronic colitis increases the risk of ischemic stroke, but it is unknown whether chronic colitis participates in ischemic brain injury directly. A combined mouse model of chronic colitis induced by dextran sodium sulfate (DSS) and ischemic stroke induced by photochemical infarction was used in this study. We demonstrated that chronic colitis significantly increased the infarction volume, activated microglia/macrophage numbers, proliferation of M1 microglia/macrophage, non-gut-derived CD4+ T lymphocyte penetration and decreased neuron numbers in the peri-infarction at 7 d after stroke. Furthermore, gut-derived CD4+ T cell accumulation on the meninges was observed at 7 d after stroke. In addition, selective depletion of meningeal macrophages resulted in a reduction of infarction volume and the non-gut-derived CD4+ T lymphocyte penetration. We concluded that chronic colitis exacerbated ischemic stroke by promoting CD4+ T cell migration from the gut to the meninges and disequilibrium of M1 and M2 microglia/macrophages. We speculated that the gut-derived CD4+ T cells may interact with meningeal macrophages and result in non-gut-derived CD4+ T lymphocyte infiltration that aggravated brain injury in ischemic stroke.

Abstract
A diet rich in salt is linked to an increased risk of cerebrovascular diseases and dementia, but it remains unclear how dietary salt harms the brain. We report that, in mice, excess dietary salt suppresses resting cerebral blood flow and endothelial function, leading to cognitive impairment. The effect depends on expansion of TH17 cells in the small intestine, resulting in a marked increase in plasma interleukin-17 (IL-17). Circulating IL-17, in turn, promotes endothelial dysfunction and cognitive impairment by the Rho kinase-dependent inhibitory phosphorylation of endothelial nitric oxide synthase and reduced nitric oxide production in cerebral endothelial cells. The findings reveal a new gut-brain axis linking dietary habits to cognitive impairment through a gut-initiated adaptive immune response compromising brain function via circulating IL-17. Thus, the TH17 cell-IL-17 pathway is a putative target to counter the deleterious brain effects induced by dietary salt and other diseases associated with TH17 polarization.

Abstract
BACKGROUND Infliximab is used in the treatment of inflammatory bowel disease. Previously reported neurological complications include central and peripheral demyelinating disorders and neuropathies occurring months into therapy. PATIENT DESCRIPTION A seven-year-old boy diagnosed with ulcerative colitis and primary sclerosing cholangitis received infliximab. Six hours following his uneventful infusion, he awoke with headache and emesis and rapidly became obtunded. Neurological examination revealed minimally reactive pupils and otherwise absent brainstem reflexes. Cranial computed tomography revealed hypodense lesions in the cerebral hemispheres, cerebellum, and pons accompanied by hemorrhage. Magnetic resonance imaging showed diffusion restriction concerning for ischemia with areas of ring enhancement suggestive of inflammation. Vessel imaging was normal, and cerebrospinal fluid and serum studies showed only an extremely elevated level of d-dimer. Echocardiogram showed depressed ventricular function but neither intracardiac shunt nor thrombus. Within four days he met criteria for brain death. Autopsy was refused. CONCLUSIONS This is the first report of a fulminant, fatal central nervous system process to occur after an initial dose of infliximab. The differential diagnosis includes multifocal arterial strokes and a devastating demyelinating process.

Abstract
There are a number of autoimmune disorders which can affect visual function. There are a very large number of mechanisms in the visual pathway which could potentially be the targets of autoimmune attack. In practice it is the retina and the anterior visual pathway (optic nerve and chiasm) that are recognised as being affected in autoimmune disorders. Multiple Sclerosis is one of the commonest causes of visual loss in young adults because of the frequency of attacks of optic neuritis in that condition, however the basis of the inflammation in Multiple Sclerosis and the confirmation of autoimmunity is lacking. The immune process is known to be highly unusual in that it is not systemic and confined to the CNS compartment. Previously an enigmatic partner to Multiple Sclerosis, Neuromyelitis Optica is now established to be autoimmune and two antibodies - to Aquaporin4 and to Myelin Oligodendrocyte Glycoprotein - have been implicated in the pathogenesis. The term Chronic Relapsing Inflammatory Optic Neuropathy is applied to those cases of optic neuritis which require long term immunosuppression and hence are presumed to be autoimmune but where no autoimmune pathogenesis has been confirmed. Optic neuritis occurring post-infection and post vaccination and conditions such as Systemic Lupus Erythematosus and various vasculitides may cause direct autoimmune attack to visual structures or indirect damage through occlusive vasculopathy. Chronic granulomatous disorders such as Sarcoidosis affect vision commonly by a variety of mechanisms, whether and how these are placed in the autoimmune panoply is unknown. As far as the retina is concerned Cancer Associated Retinopathy and Melanoma Associated Retinopathy are well characterised clinically but a candidate autoantibody (recoverin) is only described in the former disorder. Other, usually monophasic, focal retinal inflammatory disorders (Idiopathic Big Blind Spot Syndrome, Acute Zonal Occult Outer Retinopathy and Acute Macular Neuroretinitis) are of obscure pathogenesis but an autoimmune disorder of the post-infectious type is plausible. Visual loss in autoimmunity is an expanding field: the most significant advances in research have resulted from taking a well characterised phenotype and making educated guesses at the possible molecular targets of autoimmune attack.

Abstract
Preterm birth is an evolving challenge in neonatal health care. Despite declining mortality rates among extremely premature neonates, morbidity rates remain very high. Currently, perinatal diffuse white matter injury (WMI) is the most commonly observed type of brain injury in preterm infants and has become an important research area. Diffuse WMI is associated with impaired cognitive, sensory and psychological functioning and is increasingly being recognized as a risk factor for autism-spectrum disorders, ADHD, and other psychological disturbances. No treatment options are currently available for diffuse WMI and the underlying pathophysiological mechanisms are far from being completely understood. Preterm birth is associated with maternal inflammation, perinatal infections and disrupted oxygen supply which can affect the cerebral microenvironment by causing activation of microglia, astrogliosis, excitotoxicity, and oxidative stress. This intricate interplay of events negatively influences oligodendrocyte development, causing arrested oligodendrocyte maturation or oligodendrocyte cell death, which ultimately results in myelination failure in the developing white matter. This review discusses the current state in perinatal WMI research, ranging from a clinical perspective to basic molecular pathophysiology. The complex regulation of oligodendrocyte development in healthy and pathological conditions is described, with a specific focus on signaling cascades that may play a role in WMI. Furthermore, emerging concepts in the field of WMI and issues regarding currently available animal models are put forward. Novel insights into the molecular mechanisms underlying impeded oligodendrocyte maturation in diffuse WMI may aid the development of novel treatment options which are desperately needed to improve the quality-of-life of preterm neonates.

Abstract
BACKGROUND AND AIMS One of the most frequent neurologic complications reported in inflammatory bowel disease population is peripheral neuropathy; however, clinical aspects of peripheral nerve damage are not well characterized. The aim of the review is to present the existing literature on peripheral neuropathy in inflammatory bowel disease patients. METHODS A literature search identified the publications reporting on epidemiology, clinical features, underlying mechanisms and management of ulcerative colitis and Crohn's disease patients with peripheral nerve involvement. RESULTS The pathogenesis of peripheral nervous system damage in inflammatory bowel disease has yet to be elucidated, although it seems to be related to immune mechanisms; therefore, treatment with immunotherapy is recommended. In addition, peripheral neuropathy may appear as iatrogenic-related disorders associated with several drugs used in controlling inflammatory bowel disease activity; finally, peripheral neuropathy may also be caused by micronutrient deficiencies secondary to malabsorption-related disorders. CONCLUSIONS Although peripheral nervous nerve damage associated with inflammatory bowel disease is rarely reported, clinicians should be aware of the peripheral neuropathy clinical manifestations in order to recognize it and provide early treatment, which is crucial for preventing major neurologic morbidity. Heightened awareness is necessary for the successful management of these patients.

Abstract
Hepatic and gastrointestinal disorders can produce a wide spectrum of neurologic complications both affecting the central nervous system (CNS) and the peripheral nervous system. These manifestations range in severity from coma in acute liver failure and acute pancreatitis, to minor cognitive changes in chronic portosystemic encephalopathy and hepatitis C. Cerebrovascular diseases can complicate hepatitis C infection and inflammatory bowel disease. Demyelinating disorders may co-exist with inflammatory bowel disease. Anti-tumor necrosis factor alpha drugs may induce demyelination. Ataxia may occur in malabsorption syndromes and in gluten related disorders. Characteristic movement disorders are key features of acquired hepatocerebral degeneration and of Whipple disease. Multiple types of neuropathy can be found in association with hepatitis, inflammatory bowel disease and gluten related disorders.

Abstract
Objective. To describe the stroke characteristics of patients with a history of inflammatory bowel disease (IBD). Background. A hypercoagulable state associated with IBD has been frequently implicated as a risk factor for ischemic stroke. Variable mechanisms and infrequent occurrence limit prospective clinical research on the association between IBD and stroke. Methods. We retrospectively reviewed consecutive patients with acute ischemic stroke presenting to our medical center from 7/2008 to 9/2013. Patients with a history of IBD were identified. Clinical variables were abstracted from our prospective stroke registry. Results. Over the period of five years we identified only three patients with a documented history of IBD. Each of these patients presented three times to our hospital with new strokes. Patients presented outside the window for intravenous tPA treatment on 8/9 admissions. Each one of our patients had posterior strokes on at least two separate occasions. Hypercoagulation panel showed elevated factor VIII with or without concomitant elevation of Von Willebrand factor (vWF) during almost every admission (8/9 admissions). Only one admission was associated with IBD flare. Conclusion. The association between IBD and posterior strokes is a novel finding. Factor VIII elevation may serve as a biomarker of a peristroke hypercoagulable state in patients with IBD.

Abstract
Cerebral venous thrombosis (CVT) is a rare but devastating complication of inflammatory bowel disease (IBD). Here we describe six IBD patients with cerebral venous thrombosis. The patients presented with hours to days of headache and were found to have venous thrombosis on imaging. Four of the six patients had ulcerative colitis and two had Crohn's disease. All six patients were treated with therapeutic anticoagulation. There were two deaths; one patient became comatose and died despite anticoagulation while the other recovered well from the sinus thrombosis but died after a bowel perforation 3 weeks later. This case series demonstrates the critical need for early recognition of neurological symptoms in patients with IBD during disease flares. It is important to recognize the clinical signs in order to start anticoagulation expeditiously and improve neurological outcomes.

Shiue I. Chronic diseases and life events accounted for 2-18 % population attributable risks for adult hearing loss: UK Adult Psychiatric Morbidity Survey, 2007. Eur Arch Otorhinolaryngol 2015; 273:93-103.

Abstract
Links between chronic diseases and hearing loss in adults have emerged. However, previous investigations were not complete, and the role of life events was unclear. Therefore, it was aimed to examine the relationships of common chronic diseases and life events and adult hearing loss in a country-wide and population-based study. Data were retrieved from UK Adult Psychiatric Morbidity Survey, 2007, being cross-sectional, including demographics, self-reported prior health conditions and hearing loss (ever and in the last 12 months), and several major life events. Analyses included Chi square test, t test, logistic regression model, and population attributable risk estimation. People who had prior health conditions including cancer, migraine, dementia, depression, cataracts, chronic bronchitis, allergy, bowel problem, bladder problem, arthritis, muscle problem or skin problem tended to report hearing loss than their counterparts. People who have experienced major life events including post-traumatic stress disorder, serious illness of close relatives, death of family, serious problems with friends, major financial crisis, valuables stolen, being bullied, violence at home, sexual abuse or running away from home were also more likely to experience ever hearing loss problem or that in the last 12 months. 2.0-13.1 % adult hearing loss could be delayed or prevented by managing chronic diseases while 4.1-18.1 % might be delayed or prevented by minimizing the negative effects of life events. Chronic diseases and life events were associated with hearing loss in adults. Better managing lifestyle to minimize detrimental impacts in future health and nursing programs would be suggested.
