Multistate processes provide a convenient framework when interest lies in characterising the transition intensities between a set of defined states. If, however, there is an unobserved event of interest (not known if and when the event occurs), which when it occurs stops future transitions in the multistate process from occurring, then drawing inference from the joint multistate and event process can be problematic. In health studies, a particular example of this could be resolution, where a resolved patient can no longer experience any further symptoms, and this is explored here for illustration...

The typical presentation of intussusception includes intermittent severe abdominal pain, vomiting, rectal bleeding, and the presence of an abdominal mass. We present a case of intussusception after abdominal blunt trauma along with a literature review. A 4-year-old girl was admitted to the emergency department after a bicycle accident. She complained of progressively worsening abdominal pain, but there was no vomiting, fever, bloody stool, or abdominal mass. She was finally diagnosed with traumatic intussusception by ultrasonography and treated with air reduction...

BACKGROUND: Biocidal products can be sources of active substances in surface waters caused by weathering of treated articles. Marketing and use of biocidal products can be limited according to the European Biocidal Products Regulation if unacceptable risks to the environment are expected. Leaching of active substances from treated articles was observed in field experiments to obtain information on leaching processes and investigate the suitability of a proposed test method. RESULTS: Leaching under weathering conditions proceeds discontinuously and tends to decrease with duration of exposure...

A 62-year-old man with asthma sought care for intermittent fever, cough with expectoration, breathlessness and orthopnoea with grunting. Computed tomography revealed clusters of centrilobular nodules on both sides with a tree-in-bud appearance and mild diffuse bronchial wall thickening. Sputum sample grew pure colonies of Actinobacillus ureae which was confirmed by MALDI-TOF and 16SrRNA gene sequencing. A. ureae may be an additional bacteriologic causative agent of the tree-in-bud pattern on computed tomographic scan...

BACKGROUND: Cardiac resynchronization therapy (CRT) is a medical device to help cardiac synchronized contractility by electrical impulses. Improvement of symptoms and left ventricular systolic function, reducing hospital admissions and mortality in patients with moderate to severe heart failure are the main benefits of administration of cardiac resynchronization therapy. CASE REPORT: In this article, we describe a case of heart failure and left bundle branch block (LBBB) who was candidate for cardiac resynchronization therapy; but after managing hyperkalemia, left bundle branch block resolved, ejection fraction increased and cardiac resynchronization therapy implantation was canceled...

BACKGROUND: Gynandroblastoma is an extremely rare ovarian sex cord tumor with malignant potential. CASE: An 18-year-old adolescent experienced intermittent vaginal bleeding. A year later, right adnexal mass with a heterogeneous imaging appearance was identified. Laparoendoscopic single-site ovarian tumorectomy was performed. A histopathological examination showed gynandroblastoma composed of juvenile granulosa and Sertoli-Leydig cells. Since the tumor was upstaged to stage Ic due to cyst rupture during surgery, three cycles of adjuvant chemotherapy with carboplatin and paclitaxel were added...

Participation in recreational physical activity is widely acknowledged to provide significant health benefits. Conversely, intense training imposes several constraints, such as intermittent or chronic metabolic and psychogenic training stressors and maintenance of very low body fat to maximize performance. Adolescent and adult athletic women are therefore at risk of overtraining and/or poor dietary intake, which may have several consequences for endocrine function particularly on hypothalamic-pituitary-gonadal axis...

Lead (Pb) and cadmium (Cd) contamination of soil and its harmful effects on human and environmental health have been one concern. In this study, batch and column leaching experiments were conducted to investigate the effects of two EDTA-assisted leaching methods, continuous and intermittent (dry-wet alternate), on the removal of Pb and Cd from contaminated soil. Total content and fractions of Pb and Cd at every 1 cm soil column depth were analyzed before and after the leaching. The results indicated that continuous leaching removed 75...

Desiccation and re-flooding processes play a key role on hydrological features of non-perennial rivers. This study addresses the effects of these processes on the aquatic quality and unravels underlying biogeochemical processes of an intermittent river reach in southern Greece containing a spring-fed pool. Combined spatio-temporal sampling for physicochemical parameters, major ions and nutrients and high frequency automatic monitoring during a hydrological year (2010-2011) indicate that during the dry period, solute variation was controlled by "concentration" processes (i...

INTRODUCTION: Pyoderma gangrenosum (PG) is a neutrophilic dermatosis that may be associated with systemic diseases. The association of PG with lymphoid malignancies has rarely been reported. Extranodal natural killer/T-cell lymphoma (ENKTL) is a rare but aggressive entity with a poor prognosis. Here, we report the case of a patient who had idiopathic PG refractory to systemic steroids and subsequently developed ENKTL. CASE REPORT: A 70-year-old man presented with a 2-month history of intermittent fever and multifocal painful papules, plaques, and ulcerations on his extremities...

Deficits in cognitive flexibility are prominent in stress-related psychiatric disorders, including depression. Ketamine has rapid antidepressant efficacy, but it is unknown if ketamine improves cognitive symptoms. In rats, 2 weeks chronic intermittent cold (CIC) stress impairs reversal learning, a form of cognitive flexibility mediated by the orbitofrontal cortex (OFC) that we have used previously to model cognitive dysfunction in depression. We have shown that activating JAK2/STAT3 signaling in the OFC rescued the CIC stress-induced reversal learning deficit...

Functional connectivity changes in the attention network are viewed as a physiological signature of visual spatial neglect (VSN). The left dorsal lateral prefrontal cortex (LDLPFC) is known to initiate and monitor top-down attentional control and dynamically adjust behavioral performance. This study aimed to investigate whether increasing the activity of the LDLPFC through intermittent θ burst stimulation (iTBS) could modulate the resting-state functional connectivity in the attention network and facilitate recovery from VSN...

Patients with Lower Extremity Peripheral Artery Disease (LEPAD) have been recently identified as target groups for structured Cardiac Prevention and Rehabilitation (CPR) programs, whose core components and intervention goals are now well recognized. Historically, exercise training (ET) programs have been employed for the treatment of LEPAD with typical intermittent claudication, and several meta-analysis documented improvements in walking distances of enrolled patients. Both in American and European guidelines, a frequency of at least 3 sessions per week and program duration of 12 weeks were judged as optimal, while recommended sessions lengths were 30-45 minutes and 30-60 minutes respectively...

STUDY OBJECTIVE: The presence of obstructive sleep apnea (OSA) in patients with cancer appears to be accompanied by poorer outcomes. However, the mechanisms underlying such association are unknown. Tumor infiltrating lymphocytes (TILs), including CD8+ T cells, function as cytotoxic T lymphocytes (CTLs), and mount immune responses to cancer by the release of cytolytic enzymes, including granzyme B (GzmB), perforin (Prf) and cytokines such as interferon (IFN)-γ. METHODS: Using established in vivo mouse models, we investigated CD8+ T cells and cancer stem cells (CSC) in intermittent hypoxia (IH) and sleep fragmentation (SF) in the context of tumor environment...

Obstructive sleep apnea (OSA) is characterized by repetitive interruptions of breathing, causing a Chronic Intermittent Hypoxia (CIH) that can be a key step in the development and progression of cardiovascular diseases. Nowadays, in fact, there is scientific evidence showing the close relationship between OSA and atherosclerosis, even in those patients who do not show co-morbidities such as hypertension, diabetes, high levels of low-density lipoprotein (LDL), cigarette smoking and obesity, which normally are able to activate the endothelium...

PURPOSE: Our objective was to highlight the importance of database selection in observational research and to determine the incidence of corticosteroid-related events in patients exposed to fluticasone propionate intranasal spray (FPNS) compared with other intranasal steroids (INS). METHODS: After a feasibility study using an electronic medical record database in the UK (1990-2002), a retrospective cohort study was conducted using a large administrative claims database in the USA from 1994 to 2002 comparing the incidence and rate ratios of steroid-related events among intermittent, sub-chronic, and chronic FPNS use and other INS use episodes...

BACKGROUND: Some endurance athletes exhibit exercise-induced arterial hypoxemia during high-intensity exercise. Inhalation of hyperoxic gas during exercise has been shown to counteract this exercise-associated reduction in hemoglobin oxygen saturation (SaO2), but the effects of hyperoxic gas inhalation on performance and SaO2 during high-intensity intermittent exercise remain unclear. This study investigated the effects of hyperoxic gas inhalation on performance and SaO2 during high-intensity intermittent cycling exercise...

BACKGROUND: Current research regarding injuries caused during interactions between police officers and civilians is conducted intermittently or on a very narrow sample frame which provides very little clinical information about the injuries suffered or the adverse outcomes. The aim of this study is to identify comorbid risk factors and describe acute outcomes of medically treated traumatic injuries occurring as a result of contact with law enforcement personnel. METHODS: For this retrospective study, patients injured as a result of contact with law enforcement personnel were identified using ICD-9 external cause of injury codes from medical record databases of patients treated in all hospitals and trauma units in Illinois between 2000 and 2009...
