BACKGROUND: Reporting accurate surgical complication rates to patients and their families is important in the management of adolescent idiopathic scoliosis (AIS). In this study, we report the rate of major complications following the surgical treatment of AIS both in the perioperative period and among patients with a minimum of 2 years of follow-up. METHODS: We reviewed the prospectively collected data of a multicenter registry of patients who underwent surgical treatment of AIS during the period of 1995 to 2014 in order to identify all complications...

AbstractThe human microbiome is an intriguing potentially modifiable risk factor in our arsenal against Mycobacterium tuberculosis, the leading infectious disease killer globally. Previous studies have shown associations between the human microbiome and pulmonary disease states; however, etiological links between the microbiome and tuberculosis (TB) infection or disease remain unclear. Immunomodulatory roles of the microbiome may prove to be a critical asset in the host response against TB, including in preventing TB infection, reducing progression from latency, mitigating disease severity, and lowering the incidence of drug resistance and coinfections...

BACKGROUND: We occasionally encounter patients with idiopathic pulmonary fibrosis (IPF) who have similar imaging patterns to pleuroparenchymal fibroelastosis (PPFE) in the upper lung fields but are not diagnosed as PPFE clinically. The clinicopathological features and intrapulmonary distribution of elastic fibers and collagen fibers in these patients have not been fully elucidated. METHODS: We retrospectively reviewed the medical records of patients with a clinical diagnosis of IPF and selected the consecutive patients who received autopsy or pneumonectomy for lung transplantation...

Deep venous thrombosis (DVT) is common in intensive care unit (ICU) patients. It is often silent and may be complicated by pulmonary embolism and death. Thromboprophylaxis with heparin does not always prevent venous thromboembolism (VTE). Aspirin (ASA) reduces the risk of VTE in surgical and high-risk medical patients but it is unknown if ASA may prevent DVT in mechanically ventilated ICU patients. We performed a retrospective chart review of critically ill patients who received mechanical ventilation for >72 h and underwent venous ultrasonography for suspected DVT between Jan 2012 and Dec 2013...

Right ventricular (RV) failure remains a major cause of global morbidity and mortality for patients with advanced heart failure, pulmonary hypertension, or acute myocardial infarction and after major cardiac surgery. Over the past 2 decades, percutaneously delivered acute mechanical circulatory support pumps specifically designed to support RV failure have been introduced into clinical practice. RV acute mechanical circulatory support now represents an important step in the management of RV failure and provides an opportunity to rapidly stabilize patients with cardiogenic shock involving the RV...

INTRODUCTION: Chronic breathlessness is highly prevalent and distressing to patients and families. No medication is registered for its symptomatic reduction. The strongest evidence is for regular, low-dose, extended- release (ER) oral morphine. A recent large phase III study suggests the subgroup most likely to benefit have chronic obstructive pulmonary disease (COPD) and modified Medical Research Council breathlessness scores of 3 or 4. This protocol is for an adequately powered, parallel-arm, placebo-controlled, multisite, factorial, block-randomised study evaluating regular ER morphine for chronic breathlessness in people with COPD...

Endothelial to mesenchymal transition (EndMT) is a special type of epithelial to mesenchymal transition. It is a process that is characterized by the loss of features of endothelial cells and acquisition of specific markers of mesenchymal cells. A variety of stimuli, such as inflammation, growth factors, and hypoxia, regulate EndMT through various signaling pathways and intracellular transcription factors. It has been demonstrated that epigenetic modifications are also involved in this process. Recent studies have identified the essential role of EndMT in the cardiovascular system...

Bromodomain and extra-terminal domain (BET) inhibition has emerged recently as a potential therapeutic target for the treatment of many human disorders such as atherosclerosis, inflammatory disorders, chronic obstructive pulmonary disease (COPD), some viral infections, and cancer. Since the discovery of the two potent inhibitors, I-BET762 and JQ1, different research groups have used different techniques to develop novel potent and selective inhibitors. In this review, we will be concerned with the trials that used fragment-based drug discovery (FBDD) approaches to discover or optimize BET inhibitors, also showing fragments that can be further optimized in future projects to reach novel potent BET inhibitors...

Atypical lung carcinoids are intermediate-grade neuroendocrine tumors (NETs) with malignant potential. They are often detected incidentally on imaging done for non-related causes, as the patients are frequently asymptomatic. Histopathology is required to confirm the diagnosis with immunohistochemistry (IHC). Due to their indolent nature, these are often diagnosed only in the advanced stages. Treatment options include chemoradiation for widespread disease versus surgery for local or minimally invasive disease...

The environmental soot and carbon blacks (CBs) cause many diseases in humans, but their underlying mechanisms of toxicity are still poorly understood. Both are formed after the incomplete combustion of hydrocarbons but differ in their constituents and percent carbon contents. For the first time, "Sir Percival Pott" described soot as a carcinogen, which was subsequently confirmed by many others. The existing data suggest three main types of diseases due to soot and CB exposures: cancer, respiratory diseases, and cardiovascular dysfunctions...

We reported a case of disseminated Mycobacterium Kansasii (M. kansasii) infections involving skin tissue in a 57-year-old male farmer for recurrent fever, respiratory syndromes and skin lesions. Positive findings of syndromes, laboratory examinations and M. kansasii identified in the puncture fluid indicated the diagnosis of disseminated M. kansasii infections involving skin/soft tissue, pulmonary and mediastinal lymph nodes. After applying the standard HRE regime (isoniazid (300mg/d), rifampicin (600mg/d), and ethambutol (750mg/d)), the patient's temperature normalized and symptoms relieved gradually...

PURPOSE: Technological advancements and the ever-increasing use of computed tomography (CT) have greatly increased the detection of incidental findings, including tiny pulmonary nodules. The management of many "incidentalomas" is significantly influenced by a patient's history of cancer. The study aim is to determine if CT requisitions include prior history of malignancy. METHODS: Requisitions for chest CTs performed at our adult tertiary care hospital during April 2012 were compared to a cancer history questionnaire, administered to patients at the time of CT scan...

INTRODUCTION: Standard management of stage II non-small-cell lung cancer (NSCLC) is surgery, often followed by adjuvant chemotherapy. However, some patients do not undergo surgery for various reasons. We examined outcomes in this defined patient group. METHODS: We reviewed the records of patients with stage II NSCLC treated nonsurgically with curative intent from 2002 to 2012 across 3 academic cancer centers. Data collected included demographics, comorbidities, staging, treatments, and survival...

The lung is one of several moderately radiosensitive organs. Radiation-induced lung injury (RILI), including acute radiation pneumonitis and chronic radiation-induced pulmonary fibrosis, occurs most often in radiotherapy of lung cancer, esophageal cancer, and other thoracic cancers. Clinical symptoms of RILI include dry cough, shortness of breath, chest pain, fever, and even severe respiratory failure and death. The occurrence of RILI is a complex process that includes a variety of cellular and molecular interactions which ultimately leads to large fibroblast accumulation, proliferation, and differentiation, resulting in excessive extracellular matrix deposits, causing pulmonary fibrosis...

BACKGROUND: Surgical resection is an established therapeutic strategy for colorectal cancer (CRC) metastasis. However, controversies exist when CRC liver and lung metastases (CLLMs) are found concomitantly or when recurrence develops after either liver or lung resection. No predictive score model is available to risk stratify these patients in preparation for surgery, and cure has not yet been reported. PATIENTS AND METHODS: All consecutive patients who had undergone surgery for CLLMs at our institution during a 20-year period were reviewed...

Fibrosis is a common process characterized by excessive extracellular matrix (ECM) accumulation after inflammatory injury, which is also a crucial cause of aging. The process of fibrosis is involved in the pathogenesis of most diseases of the heart, liver, kidney, lung, and other organs/tissues. However, there are no effective therapies for this pathological alteration. Annually, fibrosis represents a huge financial burden for the USA and the world. 5'-AMP-activated protein kinase (AMPK) is a pivotal energy sensor that alleviates or delays the process of fibrogenesis...
