Aerosolized MMR vaccine can be used in booster campaigns in school-age children for measles and rubella, said José Luis Díaz Ortega, MD, of the Instituto Nacional de Salud Pública, Mexico, and his associates.
However, more studies of school-age children with longer follow-up of mumps antibody persistence are needed, they said.

Measles vironA 1-year serological follow-up study was done in 241 Mexican children aged 6-7 years who received vaccine MMR SII (Serum Institute of India) administered by aerosol or injection or MMR II (Merck Sharp & Dohme) by aerosol or injection. The children had a history of receiving MMR at age 1-2 years. The aerosolization was performed through a vibrating mesh nebulizer.

Measles cases has reached a 20-year high in the United States, with 288 reported as of May 23.The persistence of immunity 1 year after the booster vaccination showed 100% seropositivity for measles and rubella and 90.3%-96.6% for mumps. The differences were not statistically significant among the four groups (P = .485).
Aerosolized vaccines are not available in the United States.

Robert De Marco, MD, FCCP, was one of the first Champions Circle and Founder’s Society donors to make a major gift through insurance. We thank the De Marco family for their support in championing lung health, and it’s our pleasure to share the highlights of a recent interview with Dr. De Marco.
Why did you choose to give through insurance?
Dr. Robert De MarcoI had a Universal Life Policy that I bought when I was first in practice. While it would be a nice addition to my family bequest, it would be a much better gift to the foundation.
How was the process? Did you know anything about giving through insurance beforehand?
I knew nothing about donating insurance. I heard about it during a board strategy session and realized I had a policy that could be donated. I contacted my insurance company. I was sent forms, which were easy to fill out. The forms were then forwarded to CHEST for some signatures, and it was completed. It could not have been easier.
Would you recommend this method of giving to other donors?
Absolutely. If this policy isn’t vital to your family after you are gone, there could not be a better choice.
Why was this choice right for you and your family?
If you must take a significant amount of money out of your savings to make a sizable donation, you can put a serious dent in your retirement income. To be able to make that gift without any effect on my savings is a win-win for everyone.
Why do you continue to give to the CHEST Foundation?
I have spent my whole career trying to deal with diseases of the chest. What better way to sustain my efforts than to support a foundation dedicated to my life’s dreams? There is nothing more fulfilling than helping fund research or a project that could forever change the future of our patients’ lives. I truly believe we, as a group, are on the right path to succeeding in doing just that.
How is giving to the CHEST Foundation fulfilling to you?
How can any effort that will make the lives of our patients better not be fulfilling? Giving my time and effort without the expectation of something in return is an amazing feeling—one that I hope many donors in the future will realize. Just being a part of this great organization is a phenomenal experience.

If you own a life insurance policy that is no longer needed for its original purpose, you may consider gifting it to the CHEST Foundation.
You can also create a new policy naming the CHEST Foundation as the owner and beneficiary. An annual gift equal to the insurance premium can be given, which would provide you with a charitable deduction. The foundation would then direct the funds to the insurance provider.
This is an excellent win-win solution for you and the CHEST Foundation. For more information on these and other ways to support the CHEST Foundation, confidentially and with no obligation, contact Rudy Anderson at [email protected] or 224/521-9492.

Drs. Simpson, Hogarth, and Moores told Reddit to ask them anything—here’s what happened next.
“Is there an organ or system that sepsis generally targets?”
“If I’m going to be in the back of a cramped car cross country for 16 hours straight, should I take an aspirin beforehand to cut down risk of DVT?”
“Hello Doctor. Does thermoplasty have any application for bronchiectasis patients, like myself?”
Dr. Kyle HogarthReddit is a social news aggregation site allowing users to post a wide range of topics to create discussion. The platform is currently one of the most informative and popular social sites on the web and has a huge following of members who focus their discussions on health care/science.
Within the science AMA subsection, users have the ability to post a topic or questions about anything and respond to other users. AMA, which stands for “Ask Me Anything,” describes the conversation happening between the user and the host of the topic. Users have the ability to ask questions related to the topic, or even ‘upvote’ particular questions that they would like answered. An ‘upvote’ moves a question or comment to the top of the page to become more visible to the host. AMAs can become trending topics on Reddit through ‘upvotes’, as well.
In an effort to help educate and inform individuals on advancements in chest medicine education, clinical research, and team-based care, CHEST has connected specialists with a deep passion for topics in pulmonary, critical care, and sleep medicine to an audience filled with questions ready to be answered. Some of the topics we’ve covered include:
Sepsis with Dr. Steven Q. Simpson, FCCP, who is a pulmonologist, intensivist, CHEST board member, and a sepsis researcher and expert. Dr. Simpson discussed the recent consensus statement on sepsis diagnosis. The statement aimed to redefine the diagnostic criteria of sepsis and eliminate the concept of the systemic inflammatory response syndrome (SIRS). Dr. Simpson shared his rebuttal New Sepsis Guidelines: A Change We Should Not Make in the journal CHEST. Dr. Simpson’s statement expressed the concern that widespread application of this new SIRS definition could cost patient lives, and it should not be adopted. This AMA was upvoted 784 times.
Asthma and bronchial thermoplasty with Dr. D. Kyle Hogarth, FCCP, who is a pulmonologist, member of CHEST, and the first physician in Illinois to perform bronchial thermoplasty, a nonpharmaceutical treatment for severe asthma. This AMA was upvoted 3,112 times.
DVT with Dr. Lisa K. Moores, FCCP, who is a pulmonologist, member of CHEST, and an expert on thrombosis. Dr. Moores discussed VTE, DVT, and PE. This AMA was upvoted 903 times.
Hosting Reddit AMAs has allowed CHEST to not only reach a more public-facing audience but also health-care providers outside of chest medicine. Stepping into this platform has allowed us to position CHEST as a subject matter expert in topics like asthma, sepsis, and DVT/VTE. These AMAs have helped people to understand the role our members play within health-care by showcasing new and emerging treatments and raising public awareness of health conditions.
If you are interested in sharing your knowledge on a specific topic on Reddit, you can contact CHEST’s New Media Specialist Taylor Pecko-Reid, at [email protected].

Explore the talent of Canadian artists and the culture of Toronto during CHEST Annual Meeting 2017.
Over the last decade, Toronto’s art scene has moved to the former industrial district, creating a new home for galleries, especially those of contemporary art. While Toronto’s galleries may not be very busy outside of opening nights, they allow you to visit at any time and admire the artwork at your own pace. Along with art galleries, there are many options available to experience music and performance art, as well as family-friendly activities. Here are a few places you’ll want to visit:
Art Galleries
The Power Plant (4-minute drive), one of Toronto’s most established contemporary art galleries, is located within Harbourfront in an actual power plant - one that was in operation for most of the 1900s. If you’re with young family members, a free, hands-on art workshop led by artists with activities designed around the current exhibitions is available called Power Plant: Power Kids.
Art Metropole (15-minute drive) is a nonprofit organization with an eclectic collection of merchandise, including a huge selection of artist-created books, periodicals,
By Raysonho @ Open Grid Scheduler / Grid Engine (Own work)
Harbourfront Centreposters, clothing, audio, video, and more. The name is taken from the building’s original tenant, Art Metropole, which operated as one of Toronto’s earliest galleries from 1911 to the 1940s. Art Metropole has always been the leader of Toronto’s artistic community. In 1997, over 13,000 items were transferred to the National Gallery of Canada as the “Art Metropole Collection.” The works of world-renowned artists, such as Yoko Ono, Sol Lewitt, Joseph Beuys, and Marcel Duchamp, are included in the collection.
Daniel Faria Gallery (18-minute drive) is a bright contemporary art space found in a warehouse that used to be an auto body shop. A number of reputable, mostly Canadian, artists’ works are displayed by owner Daniel Faria, including works by Shannon Bool, Chris Curreri, Kristine Moran, and Coupland. Check out other neighboring galleries within walking distance, including Tomorrow Gallery and the artist-run Mercer Union.
Music and Theatre
The Rex Jazz & Blues Bar (6-minute drive) has two to three (mostly free) shows every day, about 19 shows a week, jazz jams on Tuesdays, local and international talent, and a fantastic location. This place is truly hard to beat.
Spend an evening at the Canadian Opera Company (6-minute drive). During the week of CHEST 2017, the COC will be showing The Elixir of Love, a Cinderella story presented with a twist, as a poor and uneducated young man dreams ofwinning the heart of a rich, clever, and beautiful woman.
For a wide variety of events and visual art, visit the Harbourfront Centre (4-minute drive). During your time at CHEST 2017, you’ll find options for literary arts, like the International Festival of Authors, theatre, music, shopping, and more. You may even get a chance for family skating on the Natrel Rink, which opens in November!
Note: all estimated times assume you are starting at the Metro Toronto Convention Centre.The arts and culture of Toronto are sure to inspire you, as will CHEST 2017. When you visit Toronto, October 28 to November 1, you’ll have access to cutting-edge education on pulmonary, critical care, and sleep medicine topics.

Down syndrome (DS) is the most common chromosomal disorder with an estimated 250,700 children, teens, and adults living with DS in the United States in 2008 (CDC.gov). The life expectancy for individuals with DS has increased due to improved medical care, educational interventions, and identification and management of underlying psychiatric and behavioral problems. This has resulted in increased median age to 49 years, and the life expectancy of a 1-year-old child with DS to more than 60 to 65 years (Bittles et al. Dev Med Child Neurol. 2004;46[4]:282).
Sleep medicine specialists have been very involved in the care of the pediatric DS population but with the improved survival, more adult patients with DS are presenting to sleep clinics for their care. The complexity of caring for adult patients with DS poses a challenge to sleep specialists, especially with the paucity of literature and clinical guidelines.
Dr. Fidaa ShaibOSA is more prevalent in children with DS (30% to 55%) compared with control subjects (2%). This high OSA prevalence further increases to 90% in adults with DS and is associated with more oxygen desaturation, hypoventilation, and sleep disruption (Trois et al. J Clin Sleep Med. 2009;5[4]:317). Childhood risk factors for OSA in DS are mostly related to hypotonia, relatively large tongue, tonsillar and adenoid hypertrophy, and the small airway. Obesity, hypothyroidism, and, more importantly, advancing age contribute to the increased risk of OSA in adults with DS. Central sleep apnea is relatively rare in adults with DS (Esbensen. Int Rev Res Ment Retard. 2010;39(C):107).
A bidirectional relationship exists between sleep disorders and mood and cognitive problems in this population. The frequency of OSA diagnosis is increased in adults with DS who present with new-onset mood disorder or declining adaptive skills (Capone et al. Am J Med Genet A. 2013;161A[9]:2188). OSA in DS is associated with sleep disruption, decreased slow wave sleep, and intermittent hypoxemia that are thought to contribute to the mechanism of declining cognitive function and memory. Given that individuals with DS are genetically at increased risk for diffuse senile plaque formation in the brain (a characteristic pathologic finding in Alzheimer’s disease brain), the super-imposed sleep fragmentation and intermittent hypoxia may accelerate the cognitive decline (Fernandez et al. J Alzheimers Dis Parkinsonism. 2013;3[2]:124).
In addition, sleep in adults with DS is characterized by a high incidence of sleep fragmentation and circadian misalignment with delayed sleep onset and early morning awakenings (Esbensen. J Intellect Disabil Res. 2016;60[1]:68). The DS population is also at increased risk for developing depression, anxiety, obsessive-compulsive tendencies, and behavioral issues. It is also worth noting that there is a tenfold increase in autism spectrum disease in this population, and a rare condition of developmental regression in adolescents with DS has recently been recognized. Patients usually present with rapid, atypical loss of previously attained skills in cognition, socialization, and activities of daily living that may further complicate their care. The regression occurs with maladaptive behaviors that develop in relation to new transitions, hormonal or menstrual changes, or major life events (Jensen et al. Br Med J. 2014;349:g5596). As a result, new behavioral sleep problems may emerge, or challenges to the treatment of existing sleep disorders may ensue. All of the aforementioned conditions alone or in combination pose additional challenges for the management of sleep problems in this population.
Adults with DS continue to manifest the same spectrum of health problems as children with DS. Adults with DS also tend toward premature aging, which puts them at risk for additional health problems seen in the geriatric population (Covelli et al. Int J Rehabil Res. 2016;39[1]:20). Adults with DS will age earlier and two times faster than control subjects (Nakamura et al. Mech Ageing Dev. 1998;05:89). Coexisting obesity and worsening cognitive function that further increase after the age of 40 will make multiple aspects of medical management very challenging (Carfi et al. Front Med. 2014;1:51).
The care of the adult patient with DS can be best delivered through a multidisciplinary team, led by physicians well informed about the specific needs of this population. The role of the sleep specialist is essential, given the implications of sleep on health and cognitive and behavioral function. The approach to diagnosing disorders of sleep timing, quality, and duration includes a focused history. Incorporating actigraphic monitoring provides additional information that can be relevant and useful. The value of the parent-reported sleep diary becomes less and less reliable as patients enter adolescence and adulthood. Attended sleep studies are widely utilized for diagnosing sleep-disordered breathing, but their value in guiding therapy is debatable. There are multiple factors that can affect the validity of a single night of sleep testing for the individual patient. Such factors include poor sleep achieved in a strange environment and sleep position variations when compared with sleep at home. There is no evidence yet to support the use of portable sleep testing in this population.
Establishing and maintaining routines are critical in different aspects of the care of this special population, particularly in relation to behavioral sleep problems. Success is dependent on the caregiver’s approach and level of involvement in their care, the individual’s intellectual ability, and the presence of other comorbidities. Management of obesity with counseling on healthy diet and participation in exercise programs are also integral parts of their care.
Although treatment with positive airway pressure (PAP) is thought to be effective in treating OSA in DS, little data are available to support its efficacy and benefits. Treatment of OSA with PAP can be very challenging. Our sleep center experience incorporates a personalized approach with gradual PAP desensitization in addition to positive feedback and a reward system to encourage and maintain use. We also utilize behavioral therapy to encourage avoidance of supine sleep in order to decrease the severity of OSA in patients who do not accept or tolerate PAP. Surgical interventions based on assessment of the upper airway during sleep through dynamic imaging or sleep endoscopy may also be considered. A recent report of hypoglossal nerve stimulation therapy in an adolescent with severe OSA suggests a potentially new alternative option for therapy (Diercks et al. Pediatrics. 2016;137(5). doi: 10.1542/peds.2015-3663.
It seems intuitive that the management of sleep disorders in adult patients with DS positively contributes to their care and promotes their overall wellbeing. Adult patients with DS continue to present particular diagnostic and therapeutic challenges that have become even more complex as their life expectancy has increased. Further research and clinical guidelines are momentously needed in order to guide the management of sleep disorders for this particularly challenging patient population.

Update: 8th ed IASLC lung cancer staging guidelines
The new 8th edition guidelines on the staging of non-small cell lung cancer sponsored by the International Association for the Study of Lung Cancer (IASLC), and developed jointly by the American Joint Committee on Cancer and the Union Internationale Contre le Cancer were enacted January 1, 2017, and provide a methodologically rigorous update to staging nomenclature (Detterbeck et al. Chest. 2017;151[1]:193). The new guidelines were developed using a database comprising 94,708 patients in 16 countries, integrating clinical, pathologic, and survival data with multivariate analysis to establish prognostically significant staging subgroups.
In the new guidelines, tumor size has been divided into 1-cm increments for T classifications with new subcategories of T1a <1 cm, T1b 1-2 cm, and T1c 2-3 cm (Rami-Porta et al. J Thorac Oncol. 2015;10[7]:990). Furthermore, T2 has been broadened to include main bronchus tumors causing lobar or whole lung atelectasis extending to the hilum. Tumors with diaphragmatic involvement have been reclassified as T4. Guidance on heterogeneous nodules has also been provided, with emphasis on measurement of the solid component (based on imaging) or depth of invasion (on pathology) to determine T classification.
The N classification remains unchanged from the 7th edition. Exploratory analysis suggested prognostic significance to the number of involved N1/N2 lymph nodes; however, this requires detailed pathologic assessment and was not adopted as a staging criterion (Asamura et al. J Thorac Oncol. 2015;10[12]:1675).
Classification of metastatic disease has been modified from M1a/M1b to M1a for thoracic metastasis, M1b for single/oligometastatic extrathoracic metastasis, and the new category M1c for multiple/disseminated metastases. M1c involvement now denotes stage IVb disease, with lower survival compared to IVa disease (0% vs 10% 5-year survival (Goldstraw et al. J Thorac Oncol. 2015;11[1]:39). Application in broader cohorts, including patients undergoing bronchoscopic staging, will be needed to further validate the new guidelines.

6-minute walk test
The 6-minute walk test (6MWT) is a widely used measure of functional status and exercise capacity. Though it does not diagnose specific etiologies of impairment, the 6MWT provides an assessment of the overall integrated physiologic responses to exercise (Am J Respir Crit Care Med. 2002;166[1]:111). The test is a self-paced, submaximal study. Patients are instructed to “walk as far as possible for 6 minutes” with this distance (6MWD) measured as the primary outcome. 6MWD is associated with clinical outcomes in many cardiopulmonary disorders and is reliable, valid, and responsive to treatment. Normative equations provide predicted and lower limit of normal values (Singh et al. Eur Respir J. 2014;44[6]:1447). In addition to patient comorbidities, several important factors impact 6MWD interpretation. Standardization of the testing course, patient instructions, encouragement, technician assistance, walking aids, and supplemental oxygen use are important in reducing testing variability (Holland et al. Eur Respir J. 2014;44[6]:1428). A significant learning effect exists during the first several walks. An improvement of about 26 m (range 24-29 m) has been reported in patients with COPD, with the majority improving during the second test despite a short time interval lapse. Assessing for longitudinal change in serial testing is based on the minimal clinically important difference (MCID). This represents the difference in 6MWD that is perceived as important to the patient or leads to change in management. Techniques to develop these estimates are based upon statistical analysis of study sample data (distribution-based) or changes in a different, but related, clinical variable that is used as a reference (anchor-based). While minor differences in MCID are reported based on specific disease processes, a European Respiratory Society/American Thoracic Society review based on data from patients with COPD, ILD, and PAH found a MCID value of about 30 m (range 25-33 m) for adults with chronic respiratory disease, independent of specific disease, which is only slightly larger than the short term variability (Puente-Maestu et al. Eur Respir J. 2016;47[2]:429). Knowledge of these factors can assist in proper interpretation of the 6MWT.

Methamphetamine-associated pulmonary hypertension (MAPAH): “tip of the iceberg”
Pulmonary hypertension (PH) is a devastating condition with serious morbidity and mortality. The Evian Classification and more recent revisions (J Am Coll Cardiol. 2013;62(25 Suppl ):D34) reclassified PH into five subgroups based upon etio-pathogenesis. Group I PH (pulmonary arterial hypertension, PAH) represents a growing list of entities, with Drugs & Toxins (Group 1.3) as a separate subgroup. This subgroup was first recognized following the discovery of an association between PH and the ingestion of the anorexigen aminorex (Gurtner HP. Schweiz Med Wochenschr. 1985;115[24]:818).
Methamphetamine (ME) as a potential etiology for PAH was first reported in 1993 (Schaiberger et al. Chest. 1993;104[2]:614). More recently, Chin et al suggested an association between stimulant use and PAH in 28.9% of their patients diagnosed with idiopathic PAH (Chest. 2006;130[6]:1657). The growing body of evidence linking ME to PAH resulted in upgrading of ME from “Possible” to “Likely” in the latest revision of the PH classification.
Recent gene sequencing data showed carboxylesterase-1, an enzyme that protects against ME-mediated pulmonary vascular injury, may be downregulated in patients with methamphetamine-associated PAH (MAPAH) (Perez et al. Am J Respir Crit Care Med. 193;2016:A2912). Furthermore, amphetamines promote mitochondrial dysfunction and DNA damage in pulmonary hypertension (Chen PI. JCI Insight. 2017;2[2]:e90427). Importantly, Barnett et al demonstrated a poorer prognosis in MAPAH compared with individuals with idiopathic PAH, but they are less likely to be treated with infused prostanoid therapies (Circulation. 2012;126:A13817).
Amphetamine-type stimulants have become the second most widely used class of illicit drugs worldwide (United Nations Office on Drugs & Crime. World Drug Report 2012). An estimated 4.7 million Americans (2.1% of the US population) have tried MA at some time in their lives (J Psychoactive Drugs. 2000;32[2]:137). The true incidence and prevalence of MAPAH remains unknown. One can surmise that with the widespread use of ME, we are only witnessing the “tip of the iceberg.”

Immunotherapy for lung cancer
The management of non-small cell lung cancer has traditionally focused on surgical resection of early and limited stage tumors and radiation and cytotoxic chemotherapy for patients with advanced disease. Recent progress in the management of patients with metastatic lung cancer treatment has concentrated on the precise histologic diagnosis and the characterization of molecular drivers of malignant progression. Distinguishing small cell from non-small cell carcinomas, as well as differentiating adenocarcinoma from squamous cell carcinomas, enables clinicians to more effectively tailor appropriate chemotherapy. The identification of molecular mutations in EGFR (epidermal growth factor receptor) or fusions in ELM4-ALK translocations as drivers of the malignant process has facilitated tumor regression by targeting the molecular pathways with small molecular inhibitors (tyrosine-kinase inhibitors) or synthetic antibodies. Unfortunately, not all lung cancers carry activating mutations, and those that do may develop resistance to this molecular-targeted approach and show tumor progression.
Immunotherapy, an anticancer therapeutic approach that activates the host immune system to target the tumor, has historically been either a broad spectrum management utilizing immune cytokine modifiers to augment host immune activity or a directed adaptive recruitment and stimulation of host lymphocytes to attack targeted tumor cells. More recently, immunotherapy has taken a targeted molecular approach to modify immune checkpoint inhibitory pathways, the “brakes” of the immune system that tumor cells have manipulated to evade immune surveillance. Cancer cells may be attacked by activated T cells through the MHC complex and T cell receptor pathways. However, cancer cells that express a checkpoint ligand can deactivate T cells through its checkpoint pathway. Cancer cells may evade immune recognition by signaling inhibitory checkpoint receptor pathways, such as PD-1/PDL-1, or CTLA-4 receptors. Blocking the checkpoint inhibition may reactivate the immune response and enhance host immune recognition and killing of tumor cells. Infusions containing FDA-approved nivolumab (Opdivo) and pembrolizumab (Keytruda) block the PD-1 receptor checkpoint, whereas atezolizumab (Tecentriq) blocks PD-L1, the ligand that binds PD-1. These immune therapeutic approaches have been successfully utilized in a variety of solid tumors, including lung cancer and malignant melanomas. Impressive clinical results of prolonged tumor regression have been demonstrated in second-line immunotherapy with improvements over chemotherapy; newer immunotherapy trials have demonstrated efficacy in the first-line setting for metastatic disease. Tumors with high PDL-1 expression and high mutational load predict improved immunotherapy outcomes. As expected, blocking checkpoint immune inhibition may lead to autoimmune-like conditions of pneumonitis, hepatitis, colitis, and dermatitis. Tumor tissue markers predictive of a therapeutic immune response are in the research phase. Immunotherapy against lung cancer adds to the therapeutic armamentarium of cancer management and provides an exciting new research arena into the biology and immunology of lung cancer.

Update: 8th ed IASLC lung cancer staging guidelines
The new 8th edition guidelines on the staging of non-small cell lung cancer sponsored by the International Association for the Study of Lung Cancer (IASLC), and developed jointly by the American Joint Committee on Cancer and the Union Internationale Contre le Cancer were enacted January 1, 2017, and provide a methodologically rigorous update to staging nomenclature (Detterbeck et al. Chest. 2017;151[1]:193). The new guidelines were developed using a database comprising 94,708 patients in 16 countries, integrating clinical, pathologic, and survival data with multivariate analysis to establish prognostically significant staging subgroups.
In the new guidelines, tumor size has been divided into 1-cm increments for T classifications with new subcategories of T1a <1 cm, T1b 1-2 cm, and T1c 2-3 cm (Rami-Porta et al. J Thorac Oncol. 2015;10[7]:990). Furthermore, T2 has been broadened to include main bronchus tumors causing lobar or whole lung atelectasis extending to the hilum. Tumors with diaphragmatic involvement have been reclassified as T4. Guidance on heterogeneous nodules has also been provided, with emphasis on measurement of the solid component (based on imaging) or depth of invasion (on pathology) to determine T classification.
The N classification remains unchanged from the 7th edition. Exploratory analysis suggested prognostic significance to the number of involved N1/N2 lymph nodes; however, this requires detailed pathologic assessment and was not adopted as a staging criterion (Asamura et al. J Thorac Oncol. 2015;10[12]:1675).
Classification of metastatic disease has been modified from M1a/M1b to M1a for thoracic metastasis, M1b for single/oligometastatic extrathoracic metastasis, and the new category M1c for multiple/disseminated metastases. M1c involvement now denotes stage IVb disease, with lower survival compared to IVa disease (0% vs 10% 5-year survival (Goldstraw et al. J Thorac Oncol. 2015;11[1]:39). Application in broader cohorts, including patients undergoing bronchoscopic staging, will be needed to further validate the new guidelines.

6-minute walk test
The 6-minute walk test (6MWT) is a widely used measure of functional status and exercise capacity. Though it does not diagnose specific etiologies of impairment, the 6MWT provides an assessment of the overall integrated physiologic responses to exercise (Am J Respir Crit Care Med. 2002;166[1]:111). The test is a self-paced, submaximal study. Patients are instructed to “walk as far as possible for 6 minutes” with this distance (6MWD) measured as the primary outcome. 6MWD is associated with clinical outcomes in many cardiopulmonary disorders and is reliable, valid, and responsive to treatment. Normative equations provide predicted and lower limit of normal values (Singh et al. Eur Respir J. 2014;44[6]:1447). In addition to patient comorbidities, several important factors impact 6MWD interpretation. Standardization of the testing course, patient instructions, encouragement, technician assistance, walking aids, and supplemental oxygen use are important in reducing testing variability (Holland et al. Eur Respir J. 2014;44[6]:1428). A significant learning effect exists during the first several walks. An improvement of about 26 m (range 24-29 m) has been reported in patients with COPD, with the majority improving during the second test despite a short time interval lapse. Assessing for longitudinal change in serial testing is based on the minimal clinically important difference (MCID). This represents the difference in 6MWD that is perceived as important to the patient or leads to change in management. Techniques to develop these estimates are based upon statistical analysis of study sample data (distribution-based) or changes in a different, but related, clinical variable that is used as a reference (anchor-based). While minor differences in MCID are reported based on specific disease processes, a European Respiratory Society/American Thoracic Society review based on data from patients with COPD, ILD, and PAH found a MCID value of about 30 m (range 25-33 m) for adults with chronic respiratory disease, independent of specific disease, which is only slightly larger than the short term variability (Puente-Maestu et al. Eur Respir J. 2016;47[2]:429). Knowledge of these factors can assist in proper interpretation of the 6MWT.

Methamphetamine-associated pulmonary hypertension (MAPAH): “tip of the iceberg”
Pulmonary hypertension (PH) is a devastating condition with serious morbidity and mortality. The Evian Classification and more recent revisions (J Am Coll Cardiol. 2013;62(25 Suppl ):D34) reclassified PH into five subgroups based upon etio-pathogenesis. Group I PH (pulmonary arterial hypertension, PAH) represents a growing list of entities, with Drugs & Toxins (Group 1.3) as a separate subgroup. This subgroup was first recognized following the discovery of an association between PH and the ingestion of the anorexigen aminorex (Gurtner HP. Schweiz Med Wochenschr. 1985;115[24]:818).
Methamphetamine (ME) as a potential etiology for PAH was first reported in 1993 (Schaiberger et al. Chest. 1993;104[2]:614). More recently, Chin et al suggested an association between stimulant use and PAH in 28.9% of their patients diagnosed with idiopathic PAH (Chest. 2006;130[6]:1657). The growing body of evidence linking ME to PAH resulted in upgrading of ME from “Possible” to “Likely” in the latest revision of the PH classification.
Recent gene sequencing data showed carboxylesterase-1, an enzyme that protects against ME-mediated pulmonary vascular injury, may be downregulated in patients with methamphetamine-associated PAH (MAPAH) (Perez et al. Am J Respir Crit Care Med. 193;2016:A2912). Furthermore, amphetamines promote mitochondrial dysfunction and DNA damage in pulmonary hypertension (Chen PI. JCI Insight. 2017;2[2]:e90427). Importantly, Barnett et al demonstrated a poorer prognosis in MAPAH compared with individuals with idiopathic PAH, but they are less likely to be treated with infused prostanoid therapies (Circulation. 2012;126:A13817).
Amphetamine-type stimulants have become the second most widely used class of illicit drugs worldwide (United Nations Office on Drugs & Crime. World Drug Report 2012). An estimated 4.7 million Americans (2.1% of the US population) have tried MA at some time in their lives (J Psychoactive Drugs. 2000;32[2]:137). The true incidence and prevalence of MAPAH remains unknown. One can surmise that with the widespread use of ME, we are only witnessing the “tip of the iceberg.”

Immunotherapy for lung cancer
The management of non-small cell lung cancer has traditionally focused on surgical resection of early and limited stage tumors and radiation and cytotoxic chemotherapy for patients with advanced disease. Recent progress in the management of patients with metastatic lung cancer treatment has concentrated on the precise histologic diagnosis and the characterization of molecular drivers of malignant progression. Distinguishing small cell from non-small cell carcinomas, as well as differentiating adenocarcinoma from squamous cell carcinomas, enables clinicians to more effectively tailor appropriate chemotherapy. The identification of molecular mutations in EGFR (epidermal growth factor receptor) or fusions in ELM4-ALK translocations as drivers of the malignant process has facilitated tumor regression by targeting the molecular pathways with small molecular inhibitors (tyrosine-kinase inhibitors) or synthetic antibodies. Unfortunately, not all lung cancers carry activating mutations, and those that do may develop resistance to this molecular-targeted approach and show tumor progression.
Immunotherapy, an anticancer therapeutic approach that activates the host immune system to target the tumor, has historically been either a broad spectrum management utilizing immune cytokine modifiers to augment host immune activity or a directed adaptive recruitment and stimulation of host lymphocytes to attack targeted tumor cells. More recently, immunotherapy has taken a targeted molecular approach to modify immune checkpoint inhibitory pathways, the “brakes” of the immune system that tumor cells have manipulated to evade immune surveillance. Cancer cells may be attacked by activated T cells through the MHC complex and T cell receptor pathways. However, cancer cells that express a checkpoint ligand can deactivate T cells through its checkpoint pathway. Cancer cells may evade immune recognition by signaling inhibitory checkpoint receptor pathways, such as PD-1/PDL-1, or CTLA-4 receptors. Blocking the checkpoint inhibition may reactivate the immune response and enhance host immune recognition and killing of tumor cells. Infusions containing FDA-approved nivolumab (Opdivo) and pembrolizumab (Keytruda) block the PD-1 receptor checkpoint, whereas atezolizumab (Tecentriq) blocks PD-L1, the ligand that binds PD-1. These immune therapeutic approaches have been successfully utilized in a variety of solid tumors, including lung cancer and malignant melanomas. Impressive clinical results of prolonged tumor regression have been demonstrated in second-line immunotherapy with improvements over chemotherapy; newer immunotherapy trials have demonstrated efficacy in the first-line setting for metastatic disease. Tumors with high PDL-1 expression and high mutational load predict improved immunotherapy outcomes. As expected, blocking checkpoint immune inhibition may lead to autoimmune-like conditions of pneumonitis, hepatitis, colitis, and dermatitis. Tumor tissue markers predictive of a therapeutic immune response are in the research phase. Immunotherapy against lung cancer adds to the therapeutic armamentarium of cancer management and provides an exciting new research arena into the biology and immunology of lung cancer.

Two-dose human papillomavirus (HPV) vaccine trials appear to show effective immunological responses in teen girls, said Maddalena D’Addario of the University of Bern, Switzerland, and her associates.
In seven controlled trials in 11 countries that directly compared two-dose and three-dose HPV vaccine schedules, teen girls receiving two doses of HPV vaccine with a 6-month interval between them had noninferior antibody responses to HPV16 and HPV18 for at least 2 years, compared with girls receiving three doses.

In one study in India, teen girls who received two or three doses of HPV vaccines developed no persistent new HPV infections. When comparing different two-dose schedules, those with longer intervals between doses had higher geometric mean concentrations of antibodies.
National Cancer Institute
A limitation to this study is that there is no established immune correlate of protection, so the clinical significance of HPV antibody concentrations is uncertain, the researchers cautioned.

Where are they now? What have they been up to? CHEST’s Past Presidents each forged the way for the many successes of the American College of Chest Physicians, leading to enhanced patient care around the globe. Their outstanding leadership and vision are evidenced today in many of CHEST’s strategic initiatives. Let’s check in with our first woman President, Dr. Deborah Shure.
Deborah Shure, MD, Master FCCP
President 1995-1996
When I began my year as President of the American College of Chest Physicians in 1995 in New York City, I became the first woman to serve in that role in the then 60-year history of the College. One major theme for my presidential year was inclusiveness. With the support of the Regents and the members of the College, we sought to increase the roles of our International Fellows and Affiliate Members, as well as the participation of all of our FCCPs. We also expanded the role of the College in global tobacco control.
Dr. Deborah Shure
With a focus on these goals, the presidential year was truly an exciting and fulfilling one. I was honored to meet so many members worldwide and, through the College, enable the support of regional meetings internationally. Our efforts in the Asia-Pacific area lent essential support to one of the early conferences on tobacco control in the Philippines (Asia Pacific Conference on Control of Tobacco, Subic, Philippines, 1998). My presentation in 1996 in Bangkok was the College’s first International Partnering for World Health Award to H.M. King Bhumibol of Thailand for his work in the prevention and treatment of chest diseases in Thailand, was an unforgettable experience.
My presidential year ended in San Francisco. Since that time, my professional life has been varied and interesting. I was fortunate to continue my academic career encompassing both clinical and basic research. In 2005, I tried a new path and worked for the FDA Center for Devices and Radiological Health, using my background in device development (the angioscope) and clinical trials. Since 2012, I have been using my clinical, academic, and regulatory experience as an independent consultant in clinical trial design.
On a personal note, my partner of many years, Aymarah Robles, MD, FCCP, and I were finally able to marry in January 2015. So, we are now a happy and official two pulmonary, Cuban-American household enjoying the culture of Little Havana and the many outdoor activities of Miami!
