    Interactions with caregivers during the first fewyears of life are crucial for the psychosocialdevelopment of children, and programs aimed

    at promoting parent-child interactions can be an

    important tool for modifying parental knowledge

    regarding effective care practices.

    A recent study showed that early exposure to

    an audiovisual aid (when the infant was 1 month

    of age) altered parental knowledge regarding

    such practices, whereas exposure at a later

    point (age 7 months) altered parental attitudes.

    [BMC Paediatrics2014;14:222]

    Our results support the idea that audiovisual

    materials, if properly designed and adminis-

    tered, can be an effective complementary tool

    in programs aimed at supporting parents, par-

    ticularly when dealing with their first baby, said

    the study authors, led by Dr. Anna Roia, Institute

    for Maternal and Child Health, IRCCs Ospedale

    Infantile Burlo Garofolo, Trieste, Italy. They also

    provide useful insight about the different ben-

    efits of using such visual aids at different times

    during the first year of the baby.

    The researchers contacted a convenience

    sample of 127 families living in the area imme-

    diately after birth while the mother and infant

    were still in the maternity ward. Of the families

    who agreed to participate, 53 were randomly as-

    signed to the early intervention group and 52 to

    the late intervention group.

    The intervention

    consisted of a video

    addressing four spe-

    cific activities related

    to early child develop-

    ment: reading aloud to

    the baby, early expo-

    sure to music, and pro-

    motion of early social-

    ization for the parents

    and their children. The

    video was delivered

    via a home visit by a

    psychologist. Ninety-nine families (52 in the ear-

    ly and 47 in the late group) completed the study.

    Parents in the early intervention group more

    frequently reported modification of their knowl-

    edge relating to the importance of early reading

    aloud and infant socialization. Parents in the late

    intervention group more frequently reported the

    acquisition of positive attitudes towards early

    reading aloud, early exposure to music, and pa-

    rental socialization.

    [T]he importance of an appropriate setting

    of administration, ideally through a home visit as

    in our study, cannot be overlooked, concluded

    the authors. This aspect may be even more

    important when dealing with population groups

    which, due to specific cultural or social reasons,

    are more difficult to reach out to and yet are

    those that would yield the greatest benefit from

    such interventions.

    ELVIRA MANZANO

    Anew guideline from the American Collegeof Physicians (ACP) recommends increas-ing fluid intake for patients who have had kidney

    stones, and pharmacotherapy if increased fluid

    alone is inadequate, to prevent stone recurrence.

    Increased fluid intake spread throughout the

    day can decrease the stone recurrence by at

    least half with virtually no side effects, said Dr.

    David A. Fleming, ACP president.

    The goal for increasing fluid intake is to im-

    prove urine output to a minimum of 2L a day. For

    patients who fail to reduce stone formation de-

    spite this approach, monotherapy with a thiazide

    diuretic, citrate, or allopurinol may be considered.

    [Ann Intern Med2014;161:659-667]

    The evidence for both recommendations was

    classified as low to moderate quality.

    Kidney stones (nephrolithiasis) form when

    crystals or substances that are normally pres-

    ent in the urine become highly concentrated,

    said guideline author Dr. Amir Qaseem from

    the University Health System of Pennsylvania in

    Philadelphia, Pennsylvania, US. In most cases,

    the stones consist of calcium oxalate and/or cal-

    cium phosphate, or other substances such as

    uric acid, struvite, and rarely, cystine. The lifetime

    prevalence of kidney stones is 13 percent in men

    and 7 percent in women. Five-year recurrence

    rate can reach up to 50 percent, if left untreated.

    The guideline is based on published studies

    on kidney stones from January 1948 through

    March 2014. The clinical outcomes evaluated

    for the guideline were symptomatic stone recur-

    rence, pain, urinary tract obstruction with acute

    renal impairment, infection, procedure-related ill-

    ness, emergency department visits, hospitaliza-

    tions, quality of life, and end-stage renal disease.

    Intake of fluids was one of the dietary interven-

    tions evaluated.

    In one study, patients with calcium stones

    who increased their fluid intake to achieve >2L

    of urine per day had less composite stone re-

    currence within 5 years compared with the

    control group (12.1 versus 27 percent). [J Urol

    1996;155:839-843] Another study showed that

    increased fluid intake resulted in a non-statisti-

    cally significant decrease in stone recurrence

    compared with no treatment (8 vs 56 percent)

    within 2 to 3 years of follow-up. [Urol Res

    2006;34:184-189]

    The authors, however, cautioned that drink-

    ing extra fluids may not work for some patients

    with kidney stones. It is also contraindicated in

    heart failure patients. With regard to pharma-

    cologic treatments, combination therapy with

    a thiazide diuretic, citrate or allopurinol was no

    more beneficial than any of these agents taken

    alone. Some of the adverse effects associated

    with these drugs included fatigue, gastrointesti-

    nal problems, headache and anemia.

    Funding for smoking cessation

    campaigns disclosures matter

    An increasing awareness of the harms of tobacco smoking has coincided with the growth of

    a new industry smoking cessation campaigns worldwide. With a high proportion of the

    worlds tobacco smokers, the Asia Pacific region is not an exception. A question of ethics now

    arises with regards to smoking cessation campaigns, which are being increasingly funded

    by pharmaceutical companies, in particular those with interests in nicotine replacement

    therapies (NRTs).

    CHUAH SU PING

    Akey challenge faced by anti-smoking bod-ies is that there is a lack of funds for theircampaigns. There is still a lack of awareness of

    the risk factors associated with tobacco smok-

    ing, and smoking in general is often viewed as

    an issue of personal behavior, which is inaccu-

    rate, said Dr. Carolyn Dresler, associate direc-

    tor for Medical and Health Sciences in the Office

    of Science at the US FDA Center for Tobacco

    Products Office. Its not just a behavioral prob-

    lem were dealing with; its a chemical addiction

    nicotine addiction which is a serious disease.

    With regards to the relationship between

    the pharmaceutical industry and smoking ces-

    sation, to me it depends a little on the duplicity

    of the industries involved, said Dresler. In my

    opinion, the tobacco industry are convicted liars,

    but we cannot ignore that the pharmaceutical in-

    dustry has had similar issues. However, the mis-

    sion of pharmaceutical companies is ostensibly

    for good, whereas the product produced by the

    tobacco industry, when used as indicated, kills.

    Dresler noted that she was a former medical

    director of research and development for NRT

    products at a leading pharmaceutical company.

    Market forces at play

    It is true that both smoking as well as smok-

    ing cessation are driven by market forces, said

    Dresler, highlighting a recent case in which a US

    District Court in Washington D.C., ruled against

    the US FDA in favor of cigarette makers Loril-

    lard Inc and Reynolds American Inc, who had

    sued the FDA in 2011, alleging conflicts of inter-

    est and bias by several members of the panel

    tasked with advising the FDA on tobacco-relat-

  • 8/10/2019 Medical Tribune December 2014 REG

    5/33

    DECEMBER 2014 FORUM 5

    ed issues. Their lawsuit specifically alleged that

    some committee members had conflicts of in-

    terest as they were paid expert witnesses, and

    possessed financial ties to pharmaceutical com-

    panies that manufactured smoking-cessation

    products.

    In his ruling, which took place in July 2014,

    US District Judge Richard Leon said the FDA

    had erred in determining that the members did

    not have conflicts of interest and therefore, the

    agencys appointment of those members was

    arbitrary and capricious, and tainted both the

    panel and its work. The FDA was ordered to

    reconstitute the tobacco panel and the use of

    its 2011 report on menthol cigarettes has been

    barred. [Available at https://ecf.dcd.uscourts.

    gov/cgi-bin/show_public_doc?2011cv0440-82.

    Accessed on 13 December 2014]

    It is difficult to separate conflict of interests

    and biases from something like smoking cessa-

    tion, especially when theres funding involved,

    Dresler admitted. This is because, as I men-

    tioned, there is already very little funding being

    allocated for smoking cessation campaigns,

    said Dresler. When you put it up against some-

    thing as large as the tobacco industry, with their

    large resources, and their ability to influence

    government and political decisions, its an uphill

    battle.

    Is there an ideal source of funding?

    If you have sources of funding from non-

    pharmaceutical organizations, such as non-gov-

    ernmental organizations or the health ministry,

    that would be best, said Associate Professor Dr.

    Mohamad Haniki Nik Mohamed, Deputy Dean

    at Kulliyyah of Pharmacy at the International Is-

    lamic University Malaysia. However, given the

    limitations, sometimes we do have to consider

    accepting funding from pharmaceutical compa-

    nies to facilitate certain events. In such cases,

    the funding company should not become in-

    volved in the planning of the advocacy program

    it should be completely independent.

    The worst thing to do, he stressed, would

    be to accept funding from the tobacco indus-

    try, for whatever purpose. Dr. Zarihah Zain of

    the Disease Control Disease, Ministry of Health

    Malaysia, agrees. According to Article 5.3 of

    the Framework Convention on Tobacco Control

    (FCTC), parties to the Convention should not

    partner with tobacco corporations to promote

    public health, nor accept the tobacco indus-

    trys so-called corporate social responsibility

    schemes, which are really just marketing by an-

    other name, she said.

    The Article 5.3 Guidelines also outlined trans-

    parency measures including, Disclosure of cur-

    rent or previous work with tobacco industry by

    applicants for government positions related to

    health policy, and of plans to work for tobacco

    industry by former public health officials. Also,

    disclosure of tobacco industry activities, includ-

    ing: production, manufacture, market share,

    revenues, marketing, expenditures, philanthro-

    py with penalties for providing false or mis-

    leading information. [Available at www.fctc.org/

    Discussing preferences critical

    during end-of-life care

    RADHA CHITALE

    End-of-life care discussions are tricky andnecessary, but a new survey reveals theseconversations are not happening, based on

    what patients and their families say their end-

    of-life goals are versus what they are advised by

    experts. [CMAJ2014. doi:10.1503/cmaj.140673]

    Our findings could be used to identify impor-

    tant opportunities to improve end-of-life com-

    munication and decision-making in the hospital

    setting, said lead researchers Dr. John You, as-

    sociate professor of Medicine and Clinical Epi-

    demiology and Biostatistics at McMaster Univer-

    sity in Hamilton, Ontario, Canada.

    The current literature regarding end-of-life

    care discussions suggests 11 topics that are

    considered most important by doctors, with

    little to no input from patients or families, the re-

    searchers noted.

    However, when the researchers surveyed real

    patients (mean age 81) and families about which

    topics they felt were most important, opinions

    converged to identify the following five areas:

    - preferences of care in event of life threatening

    illness

    - patient values (what is important when consid-

    ering healthcare decisions)

    - prognosis of illness

    - fears or concerns

    - additional questions regarding care

    However, it was clear that halting discussion

    there was not necessary. Patient satisfaction

    scores were directly proportional to how much

    physicians were willing to discuss end-of-life

    care. Patient satisfaction improved as they cov-

    ered more topics and as the number of times

    they had such discussions increased.

    The Canada-based survey included 233 el-

    der adults in hospital who had serious illnesses

    and 205 of their family members.

    The researchers found that end-of-life care

    discussions occurred in less than one-third of

    cases, sometimes as little as 1.4 percent of the

    time. This appeared to support national data

    showing that rates of cardiopulmonary resus-

    citation (CPR), dying in-hospital, and intensive

    care unit deaths are rising among elderly pa-

    tients with serious disease, despite the fact that

    80 percent of these patients prefer a less ag-

    gressive and more comfort-oriented end-of-life

    care plan that does not include CPR, the re-

    searchers said.

    Other topics of discussion on the 11-item list

    that patients did not identify in their top five in-

    cluded facilitating access to legal documents to

    record patient wishes and providing information

    about the outcomes, risks, benefits of comfort

    care. [Med J Aust 2007;186:S77,S79,S83-108;

    Mental disorders may cause cardiac

    symptoms

    RADHA CHITALE

    Depression, anxiety and other psychologicaldisorders are known to influence cardiacactivity and can result in cardiac symptoms even

    when tests show patients to be free of heart dis-

    ease.

    Despite this high importance, in patients

    with non-cardiac chest pain, mental disorders

    are often diagnosed too late, because cardiolo-

    gists without psychosomatic experience lack

    uncomplicated diagnostic tools to detect them

    accurately, said researchers from University

    Hospital Dresden in Germany, who surveyed

    disease-free patients about their mental state in

    order to determine the extent of the correlation.

    About 20 percent of people who suffer from

    cardiac symptoms such as chest pain or short-

    ness of breath do not have heart disease but

    they are just as likely to use healthcare resourc-

    es and can have lower quality of life. Early iden-

    tification could alleviate this problem.

    The trial included 235 patients with at least

    one cardiac symptom chest pain (55.3 per-

    cent), dyspnea (35.4 percent), or palpitations

    (39.4 percent) who were assessed for and

    did not have coronary artery disease (CAD).

    [Open Heart 2014;1:e000093.doi:10.1136/

    openhrt-2014-000093]

    These patients were given a questionnaire

    that tested for general and heart-related anxiety

    and depression, idiopathic pain with a poten-

    tially psychological root, hypochondriac ten-

    dencies, and quality of life in relation to physical

    and mental health before and 6-8 months after

    undergoing an invasive coronary angiography.

    The test revealed that 8.7 percent of patients

    reported severe cardiac symptoms prior to

    coronary angiography and 28 percent reported

    moderate symptoms.

    However, even after CAD exclusion following

    angiography, 70 percent of patients reported

    persistent symptoms.

    Compared to a population of healthy adults,

    general anxiety was higher by 37 percent

    (p

  • 8/10/2019 Medical Tribune December 2014 REG

    9/33

    DECEMBER 2014 NEWS 9

    by study participants compared to the normal

    population.

    The researchers noted they were unable to

    determine cause and effect between psycho-

    pathological symptoms and cardiac symptoms

    or vice versa. They also lacked information

    about gastrointestinal disorders, skeletal condi-

    tions or other non-cardiac causes of chest pain.

    However, the study did suggest patients with

    non-cardiac chest pain should be offered psy-

    chological or psychiatric support early in order

    to begin psychosomatic therapy, which may

    prevent patients from seeking pharmaceutical

    or procedural solutions, and to improve their

    quality of life.

    Without training, cardiologists are more likely

    to overlook psychosomatic symptoms, but the

    researchers suggested the 120-minute ques-

    tionnaire that takes 15 minutes to evaluate by a

    nurse was a practicable solution for inpatients

    and outpatients.

    These [standardized questionnaires] may

    prevent repeated utilization of the healthcare sys-

    tem and this could help to reduce costs for these

    patients due to initiation of an early psychoso-

    matic therapy, the researchers said.

    Neuroticism, long-term stress

    linked to higher risk of Alzheimers

    in women

    ELVIRA MANZANO

    Women who worry a lot and cope poorlywith stress may be at an increased risk ofdeveloping Alzheimers disease (AD) later in life,

    research suggests.

    A study of 800 women in Sweden followed

    for 38 years showed that women with the high-

    est scores on neuroticism scale and had expe-

    rienced long-term distress in midlife were twice

    as likely to develop AD than those with the

    lowest scores. [Neurology 2014; pii:10.1212/

    WNL.0000000000000907;E-pub ahead of print]

    Neuroticism is the enduring tendency to be

    in a negative emotional state. People with neu-

    rotic personality may perceive daily run-of-the-

    mill situations as alarming or depressing. They

    suffer from negativity, feelings of guilt, anxiety,

    envy and anger more frequently and more se-

    verely than other people and have difficulty

    managing stress, although they are in touch

    with reality.

    We have shown in this study that midlife

    neuroticism is associated with increased risk of

    AD, and that distress mediates this association.

    Clearly, there was a clear statistical correlation in

    those who had been exposed to a long period

    of stress, said Johansson. It is the stress itself

    that is harmful. A person with a neurotic tenden-

    cy is more sensitive to stress than other people,

    said lead researcher Dr. Lena Johansson from

    the Sahlgrenska Academy at Gothenburg Uni-

    versity in Molndal, Sweden.

    Using the Eysenck Personality Inventory

    scale, women were assessed of their dominant

    personality traits (ie, extraversion vs introversion

    and neuroticism vs stability). Dementia was di-

    agnosed according to DSM-III-R criteria, based

    on information culled from neuropsychiatric ex-

    aminations, hospital records, and registry data.

    During the study period, 153 women who had

    neurotic tendencies at midlife had developed

    some types of dementia, 104 of which had AD.

    Advancing age, family history, and genetics

    are known risk factors for AD and other demen-

    tia-related disorders. This is the first study to

    show a link between personality and AD, said

    Johansson. However, the finding does not sug-

    gest that neuroticism alone could increase the

    risk of AD.

    Personality could determine behavior, life-

    style and how we react to stress. Ultimately, all

    these may significantly affect the risk of develop-

    ing AD.

    She said future studies should exam-

    ine whether this group of women will re-

    spond well to interventions. It remains to be

    seen whether neuroticism could be modi-

    fied by medical treatment or through lifestyle

    changes.

    Reducing external knee adduction moment

    (EKAM), a surrogate measure of medial

    joint loading, by wearing lateral wedge insoles

    does not reduce knee pain in patients with

    knee osteoarthritis, according to a multination-

    al group of researchers.

    In their study, 70 patients (mean age 60.3

    years) with radiographically confirmed pain-

    ful medial knee osteoarthritis underwent a gait

    analysis whilst walking in a control shoe, a

    typical lateral wedge insole, and a supported

    wedge insole.

    The researchers compared changes in

    EKAM and knee pain scores, and found that

    significant reductions in pain were only ob-

    served when patients were using the medial

    supported lateral wedge insole (-6.29 per-

    cent vs control). However, there was no differ-

    ence in pain reduction between patients who

    experienced a decrease in EKAM and those

    who did not. Moreover, patients who experi-

    enced consistent major reductions in EKAM

    did not report a consistent reduction in knee

    pain.

    Iodothyronine deiodinases are key regulators

    of thyroid hormone metabolism and since

    thyroid hormones are functionally active in nu-

    merous tissues, deiodinase polymorphisms

    have the potential to affect multiple clinical

    endpoints.

    In a recent systematic review, researchers

    evaluated the relationship between iodothyro-

    nine deiodinase polymorphisms and a variety

    of parameters. Eligible studies were identified

    by searching the Pubmed, EMBASE, Web of

    Science, Cochrane Library, CINAHL, Academic

    Search Premier, and Science Direct databases

    for articles published up to 13 August 2013.

    The researchers found that deiodinase type

    1 (D1) polymorphisms showed a moderate-to-

    strong relationship with thyroid hormone pa-

    rameters, insulin-like growth factor 1 produc-

    tion, and risk for depression. D2 variants were

    correlated with thyroid hormone levels, insulin

    resistance, bipolar mood disorder, psychologi-

    cal well-being, mental retardation, hyperten-

    sion, and risk for osteoarthritis, and one D3

    polymorphism was associated with a risk for

    osteoarthritis. However, the researchers noted

    that the clinical implications of these associa-

    tions are far from clear and may vary among

    different populations. They commented that

    further research is required to determine the

    exact role of deiodinase polymorphisms and

    their potential as therapeutic targets.

    COPD include cigarette smoking, air pollution

    (both outdoor and indoor) and occupational

    hazards such as vapours, fumes and irritants.

    In high-income countries, smoking is the pre-

    dominant cause whereas in low-income coun-

    tries indoor air pollution associated with the

    use of fuels for cooking and heating produces

    most COPD burden. [WHO Fact Sheet No 315.

    Chronic obstructive pulmonary disease]

    COPD is now the fifth-most common cause

    of death worldwide and total deaths from COPD

    are projected to increase by more than 30 per-

    cent in the next 10 years.

    In Asian countries COPD burden is higher

    than in their Western counterparts, with more

    deaths, years spent living with disability, and

    years of life lost. This can be attributed to high

    tobacco smoking rates, poor quality of outdoor

    air and the use of biomass fuels indoors. [Int J

    Tuberc Lung Dis 2008;12:713-717]

    measures the presence and severity of airflow

    obstruction: COPD is characterised by airflow

    obstruction that is not fully reversible on the

    administration of bronchodilators. [Ann Intern

    Med2011;155:179-191]

    The priorities in management of COPD in-

    clude smoking cessation and using effective

    inhaled therapy. In patients with stable disease

    who remain breathless or experience exacer-

    bations despite use of short-acting bronchodi-

    lator reliever therapy, guidelines recommend

    the use of maintenance therapy. Those with a

    forced expiratory volume (FEV) 50 percent of

    predicted should be given either a long-acting

    beta-2 agonist (LABA) or long-acting musca-

    rinic antagonist (LAMA). When FEV falls below

    half that predicted, patients should be given

    either a LABA with an inhaled corticosteroid

    (ICS) in a combined inhaler or a LAMA. [NICE.

    Management of chronic obstructive pulmonary

    disease in adults in primary and secondary

    care. June 2010]

    The combination of ICS and LABA in a single

    device is well tolerated and results in improved

    FEV, quality of life and respiratory symptoms

    in stable COPD patients. Over time, there have

    been progressive improvements in available

    LABA and ICS therapies, allowing the develop-

    ment of treatment delivered in once-daily, sin-

    gle device format. [Int J COPD2014;9:249-256]

    Fluticasone furoate / vilanterol

    Mode of action

    Fluticasone furoate is a corticosteroid with

    anti-inflammatory activity. It is highly potent,

    binding more strongly to the glucocorticoid re-

    ceptor than other commonly used ICS, includ-

    ing fluticasone propionate, mometasone fu-

    roate, budesonide and ciclesonide. Fluticasone

    furoate also has the largest cellular accumula-

    tion and slowest rate of efflux among these ICS,

    leading to prolonged efficacy and the potential

    for once-daily dosing. [Am J Physiol Lung Cell

    Mol Physiol 2007;293:L660L667]

    Vilanterol is a long-acting beta2-adrenergic

    agonist (LABA) that stimulates intracellular ad-

    enyl cyclase to increase levels of cyclic-3,5-

    adenosine monophosphate (cAMP). Increased

    cAMP levels lead to relaxation of bronchial

    smooth muscle and inhibition of release of

    mediators of hypersensitivity. [Breo Ellipta Pre-

    scribing Information]

    Clinical efficacy

    Two clinical trials of 1 year in duration have

    demonstrated the effectiveness of fluticasone

    furoate / vilanterol compared with vilanterol

    alone. The studies enrolled patients aged 40

    years and over, with a history of COPD and

    smoking (10 pack-years) and history of one or

    more moderate-to-severe exacerbations in the

    previous year (approximately 1,300 patients in

    each study). Subjects were randomized to ei-

    ther 25 g vilanterol alone or 25 g vilanterol

    combined with either 50 g, 100 g or 200 g

    fluticasone furoate once daily. Combination

    therapy provided a significant reduction in the

    primary endpoint of annual rate of moderate-

    to-severe COPD exacerbations. [Lancet Respir

    Med2013;1:210-223]

    Two other trials have examined the effect of

    fluticasone furoate / vilanterol on lung function

    compared with placebo and each component

    alone. Both of these were 24 weeks in duration

    and enrolled patients with stable moderate-to-

    severe COPD. Acute (04 hours post-dose) and

    trough (2324 hours post-dose) effects on lung

    function were assessed. All active treatments

    improved FEV, and confirmed that fluticasone fu-

    roate / vilanterol results in significant, sustained

    bronchodilation. [Respir Med 2013;107:550-

    559, Respir Med2013;107:560-569]

    Adverse effects

    The treatment of patients with stable COPD

    with fluticasone furoate / vilanterol in combina-

    tion is usually well tolerated. Common side ef-

    fects (occurring in 5 to 10 percent of patients)

    include nasopharyngitis, upper respiratory tract

    infection, headache, dysphonia and oropha-

    ryngeal candidiasis. In the long-term clinical tri-

    als of fluticasone furoate / vilanterol, fractures

    and pneumonia were more common with the

    combination therapy. Although the overall rate

    of pneumonia was low, there were eight deaths

    due to pneumonia in the fluticasone furoate /

    vilanterol group and none with monotherapy.

    As with other inhaled LABAs, vilanterol is as-

    sociated with clinically significant cardiovascu-

    lar effects such as increased heart rate, blood

    pressure and QT interval prolongation. It should

    therefore be used with caution in patients with

    arrhythmias, acute coronary syndromes or

    heart failure. In healthy subjects however, the

    safety of single and repeat doses has been

    demonstrated, with no deleterious effects upon

    ECG measurement, QT interval or blood glu-

    cose or potassium. [Int J COPD2014;9:249-56]

    Dose and administration

    Fluticasone furoate combined with vilanterol

    is the first once-daily ICS/LABA combination to

    be available (marketed under the trade names

    Relvarand Breo). It is available in a new dry

    powder inhaler delivery device (Ellipta) which

    is designed for simplified usage. The dose for

    maintenance therapy of COPD is one inhala-

    tion daily, which delivers 100 g of fluticasone

    furoate and 25 g of vilanterol. [Breo Ellipta

    Preeclampsia is a hypertensive complica-tion of pregnancy, characterized by highblood pressure as well as possible kidney

    damage. Typically, preeclampsia occurs after

    20 weeks of pregnancy and, if untreated, can

    pose significant threats to the mother and the

    baby, especially if birth is premature. While the

    symptoms of preeclampsia go away following

    birth or more specifically, removal of the pla-

    centa the condition leaves mothers with long-

    term health risks.

    The incidence rate of preeclampsia in devel-

    oped nations is between 2 to 5 percent, higher

    in developing countries. While the overall inci-

    dence of preeclampsia is not high, the conse-

    quences are severe. In Europe, for example,

    the incidence of preeclampsia is about 3 per-

    cent, but 25 percent of perinatal mortality is

    caused by preeclampsia.

    Importantly, preeclampsia is unpredictable.

    Emerging trends in preeclampsia

    Professor Holger Stepan

    Director of ObstetricsUniversity Hospital LeipzigLeipzig, Germany

    Preeclampsia is unpredictable. The cause of disease, aggressiveness, and speed of escalation varies from patient topatient.

  • 8/10/2019 Medical Tribune December 2014 REG

    18/33

    DECEMBER 2014 FEATURE 18

    The cause of disease, aggressiveness, and

    speed of escalation varies from patient to pa-

    tient. For example, a pregnant woman in week

    24 could be feeling fine but wakes up one

    morning with some abdominal pain and if there

    are complications, her situation can shift to very

    severe within a day.

    Predicting preeclampsia

    The many other symptoms of preeclampsia

    can be equally non-specific: excess protein in

    the urine, headaches, blurred vision, nausea,

    low platelet levels, shortness of breath, swell-

    ing.

    Other cases of preeclampsia may be less

    severe. The problem is that a doctor with nor-

    mal measures to assess pregnancy cannot dif-

    ferentiate between normal, moderate, and high

    danger. Those at risk include very young preg-

    nant women (teenaged) or mature mothers

    (over 40 years), twin pregnancies, overweight

    women, women with kidney disease, and preg-

    nant women with poor placental perfusion.

    Early diagnosis is challenging, and in the

    past doctors were only able to identify pre-

    eclampsia as it occurred. However, the last de-

    cade has seen the discovery of novel biomark-

    ers that show promise both for early detection,

    risk stratification and management.

    A significant breakthrough in understand-

    ing preeclampsia came about in 2002, when

    Dr. Ananth Karumanchi, a kidney specialist at

    Harvard University in Boston, Massachusetts,

    US, observed the role of two proteins prior to

    the onset of preeclampsia. During pregnancy,

    the placenta releases placental growth factor

    (PIGF), an angiogenic factor from the VEGF

    family (a large group of proteins responsible for

    blood vessel growth). Soluble fms-like tyrosine

    kinase-1 (sFlt-1) is an antagonist to PIGF, bind-

    ing to it and inhibiting cell growth.

    In a normal pregnancy, these two proteins

    are in balance ensuring the health of mother

    and baby. Karumanchi showed that pregnant

    women with preeclampsia have too much sFlt-

    1 circulating in their blood, and too little PIGF.

    This fundamentally changed the view of pre-

    eclampsia and confirmed it as a state of imbal-

    ance between angiogenic and anti-angiogenic

    factors.

    In addition to blood pressure monitoring or

    proteinurea measures, blood tests for these

    biomarkers have the potential to identify wom-

    en at high risk of preeclampsia earlier in the

    pregnancy, before the onset of the disease.

    These types of biomarker tests are also

    helpful for differential diagnosis. Typically, one

    out of five women presenting with preeclamptic

    symptoms will go on to develop preeclampsia.

    If you can tell four of those women that they

    will not develop preeclampsia, the benefit is tre-

    mendous.

    The emerging importance of a

    biomarker ratio

    A number of studies have shown that the ra-

    tio of sFlt-1 to PlGF is more useful than either

    measure alone. The ratio has proven highly

    useful in helping clinicians identify which preg-

    nant women are at highest risk and need to be

    referred for timely interventions.

    A European study of women with differing hy-

  • 8/10/2019 Medical Tribune December 2014 REG

    19/33

    DECEMBER 2014 FEATURE 19

    pertension-related conditions and normal con-

    trols (n=630) has shown that the sFlt-1/PIGF

    ratio could be used to differentiate the various

    types of hypertensive diseases in pregnancy.

    The value was also found to correlate with the

    time span from diagnosis until delivery; women

    with the highest ratios had the shortest time

    interval from diagnosis until delivery with the

    most aggressive disease course while women

    with the lower ratios had a longer time interval

    and less aggressive disease.

    At the moment, the only cure for preeclamp-

    sia is removing the placenta. Simply lowering

    blood pressure with antihypertensive medica-

    tions will not stop preeclampsia because it is

    driven by placental proteins. The disease seems

    to originate from the placenta, if the placenta is

    not removed during delivery, preeclampsia will

    continue. And it is impossible to remove the pla-

    centa without delivering the baby.

    A specialized center with pediatricians expe-

    rienced in premature babies is critical for pre-

    eclamptic women. The goal of management is

    to monitor maternal and fetal heart rate, well

    being, ultrasound, and so on to pinpoint the

    correct time for delivery too early and there

    is risk for the baby, too late and there can be

    complications for both mother and baby.

    These placental proteins driving preeclamp-

    sia are future targets for therapies but for now,

    tracking their concentration can help indicate

    when a woman can safely deliver.

    New therapeutic approaches

    for preeclampsia

    Given the new understanding of preeclamp-

    sia as a state of angiogenic imbalance, treat-

    ments aimed at interfering with the effects of

    sFlt-1 to restore the balance have shown initial

    promise.

    Extracorporeal removal of sFlt-1 from the

    blood of a pregnant woman has shown favor-

    able initial results. The future is in determining

    whether the technique prolongs pregnancy

    and improves maternal and fetal outcomes in a

    larger patient population.

    Informed consent

    Dr. Eugene WongConsultant Orthopedic and SpineSurgeonAdjunct Assistant ProfessorPerdana University Graduate School of

    MedicineSerdang, Selangor

    Patients should be educated prior to entry into clinical trials so they may give informed consent.

    Informed consent is defined as approval orpermission given by the patient based onknowledge of the procedure or treatment to be

    performed. The information includes the risks

    and benefits, as well as alternatives to the pro-

    posed treatment.

    Patients beliefs, culture, occupation or other

    factors have a bearing on the information they

    need in order to reach a decision. Touching a

    person without consent constitutes battery and

    putting a person in fear of being touched with-

    out consent is an assault.

    Informed consent differs from implied con-

    sent. Consent is implied for gathering informa-

    tion by history taking and performing neces-

    sary examinations. Subsequent treatment plans

    need to be discussed with the patient and in-

    formed consent taken.

    There are two types of consent. The first is

  • 8/10/2019 Medical Tribune December 2014 REG

    21/33

    DECEMBER 2014 FEATURE 21

    the expressed consent, either oral or written,

    given by the patient to undergo a specific pro-

    cedure or treatment. Implied consent is inferred

    from circumstances. It is rarely documented and

    is relied upon for care or treatment that is rou-

    tine and does not involve significant risks to the

    patient. The doctor performing the procedure

    or administering the treatment in question is re-

    sponsible for engaging the patient in the con-

    sent process.

    Competence requires patients ability to un-

    derstand the consequences of their decision and

    the need of freedom from coercion. It requires

    the ability to understand the proposed treatment

    and make an informed decision. Competence is

    usually assumed unless there are indications to

    the contrary. Only an autonomous person can

    give informed consent. If the patient is incom-

    petent, proxy consent is allowed, but no more

    than minimal risk to the patients is allowed. The

    reasonable person and best interest judgment

    standards need to be applied. A risk, even if it

    is a mere possibility, should be regarded as sig-

    nificant if its occurrence can cause serious con-

    sequences.

    Adequate decision-making capacity is the

    ability to understand, evaluate and communicate.

    As a rule, consent should not be obtained from

    a sedated or anesthetized patient for an elective

    procedure. Emergency treatment without con-

    mediate need of treatment. The patient is unable

    to provide consent because of physical or mental

    impairment or because the patient is a minor. Im-

    plied consent is required in cases of emergency

    treatment, where it is presumed that the patient

    would have consented to treatment if it is neces-

    sary to save his life or from serious harm.

    Research involving clinical trials of drugs or

    treatments and research into the causes of, or

    possible treatment for, a particular condition, is

    important in increasing doctors ability to provide

    effective care for present and future patients.

    The benefits of the research may, however, be

    uncertain and may not be experienced by the

    person participating in the research. It is particu-

    larly important that you ensure that the research

    is not contrary to the individuals interests, the

    participants understand that it is research and

    that the results are not predictable.

    Giving treatment without consent is a failure to

    respect the patients autonomy and violates an

    individuals right of self-determination. The con-

    sent form is for patients to acknowledge that the

    nature and purpose of treatment has been fully

    explained, understood and consented to. Poor

    handling of informed consent can lead to com-

    plaints, medico-legal litigation and discipline for

    negligence.

    There was a strong emphasis on the roleof tobacco smoking in the developmentof lung cancer at this years Asia Pacific Lung

    Cancer Conference (APLCC) in Kuala Lumpur,

    Malaysia. However, discussion regarding anoth-

    er key risk factor outdoor air pollution was

    strangely absent from the agenda.

    The ASEAN region has 10 percent of the

    worlds smokers, with Indonesia making up 51

    percent of the distribution in the region, followed

    by the Philippines with 13.6 percent and Viet-

    nam with 12 percent, said Dr. Tara Singh Bam,

    who represents the International Union Against

    Tuberculosis and Lung Disease (The Union) in

    Indonesia. He noted that here are approximately

    127 million adult smokers in the ASEAN alone.

    Smoking is the leading preventable cause

    of death in the developed world and quickly be-

    coming so in developing countries. Currently,

    there are between 5 and 6 million deaths year-

    ly in the world, and this figure is expected to

    climb to 10 million by around 2025, said Dr.

    Carolyn Dresler, associate director for Medical

    and Health Sciences in the Office of Science

    at the FDA Center for Tobacco Products Office,

    US. If a smoker does not quit, then they have

    a 50 percent chance of dying from a tobacco-

    related disease.

    In the Resolution presented at the close of

    the conference, the first statement highlights

    that Tobacco is a key risk factor for lung can-

    cer claiming about 1.6 million lives globally ev-

    ery year. The Resolution notes that complete

    implementation of the WHO Framework Con-

    vention on Tobacco Control (WHO FCTC) is

    the most effective way forward for prevention

    of lung cancer, and the APLCC supports full

    implementation of the WHO FCTC especially in

    all countries that are party to this treaty. Addi-

    tionally, the Resolution noted, Tobacco prod-

    ucts should be explicitly excluded from future

    international, regional and bilateral trade and

    investment agreements.

    nogenic to humans (Group 1). This conclusion

    was reached by leading experts convened by

    the IARC Monographs Programme who, after

    thorough review of the latest scientific literature,

    concluded that there is sufficient evidence

    that exposure to outdoor air pollution causes

    lung cancer. [Press release no. 221, 17 October

    2013, WHO]

    Ambient air pollution (AAP) should also not

    be ignored as a major cause of mortality, says

    the WHO. In 2012 alone, 3.7 million deaths

    globally were attributable to AAP, with about 88

    percent of these deaths occurring in low- and

    middle-income countries, which represent 82

    In a meta-analysis of 13 prospective studies,

    which included almost 15,000 subjects, high ad-

    iponectin levels were observed to confer a lower

    risk of T2DM relative risk of 0.72 per 1-log g/

    mL increment in adiponectin levels. This inverse

    association was consistently observed across all

    populations, said Lam. [JAMA2009; 302:179-

    188] In addition, Lam and her colleagues study

    of non-diabetics in the Hong Kong Cardiovas-

    cular Risk Factor Prevalence Study (CRISPS)

    cohort showed that the combined use of serum

    adiponectin and tumor necrosis factor-alpha

    receptor 2 (TNF- R2) as biomarkers provid-

    ed added-value over traditional risk factors for

    T2DM prediction. [PloS one2012;7:e36868]

    The association between adiponectin and

    insulin sensitivity has also been analyzed at

    the genetic level, where evidence of a causal

    relationship was found in a study of Swedish

    men. [Diabetes 2013; 62:1338-1344] This cor-

    in diabetes and its complications

    Adiponectin is a protein synthesized and secreted predominantly by adipocytes into the

    peripheral blood. Low circulating adiponectin concentrations are associated with a variety of

    metabolic diseases and cancers, with recent studies demonstrating the potential of the protein

    as various clinical biomarkers and therapeutic targets. Professor Karen Siu Ling Lam from the

    University of Hong Kong shared some insights into the latest development in this area.

    responds to an earlier study in the CRISPS

    cohort and a subsequent meta-analysis includ-

    ing two European studies, which concluded

    that the ADIPOQ single nucleotide polymor-

    phism (SNP) T45G (rs2241766) independently

    predicted persistent hyperglycemia at 5 years

    and the development of T2DM. [Diabetologia

    2006;49:1806-1815]

    The link between adiponectin and T2DM is

    taken further with associations found between

    the protein and T2DM complications. A study

    of a large Caucasian cohort showed that a vari-

    ant of the ADIPOQ gene, adipo4 (rs266729),

    which results in low adiponectin levels, is as-

    sociated with increased carotid intima-media

    thickness (CIMT), a marker of atherosclerosis

    and a stroke risk factor, suggesting a causal

    role of adiponectin in carotid atherosclerosis.

    [Stroke 2011;42:1510-1514] This relationship

    was also observed in a multi-ethnic population

    and was even more marked in those with T2DM.

    [Stroke2012;43:1123-1125] Hui et al confirmed

    this relationship in a prospective study in the

    CRISPS cohort, whereby low serum adiponec-

    tin independently predicted progression of ca-

    rotid atherosclerosis identified via CIMT incre-

    ments over the years. [Metab Syndr Relat Disord

    2014 Epub ahead of print] All these suggest that

    adiponectin participates in the development of

    carotid atherosclerosis. However, this was not

    the case in ischemic stroke patients, although

    serum adiponectin was indeed lower compared

    to controls. A meta-analysis of eight prospec-

    tive studies showed that in the long term, serum

    adiponectin levels did not predict incidence, but

    instead was found to be a good predictor of the

    5-year survival rate following the first episode of

    ischemic stroke. [Stroke 2014;45:10-17; Stroke

    2005;36:1915-1919]

    In almost all populations studied, there was

    a clear indication that a high level of adiponectin

    is protective against incident myocardial infarc-

    tion (MI), even after correcting for cholesterol

    levels. This produced up to a 40 percent MI risk

    reduction in the Healthcare Professionals Fol-

    low-up Study, said Lam. In obese individuals

    who did not undergo bariatric surgery, a follow-

    up of 10 years found that a protective effect for

    the development of T2DM and MI was conferred

    by adiponectin. This was confirmed by a 16-year

    longitudinal study in the CRISPS cohort in which

    the ADIPOQ gene +276G>T (rs1501299) SNP

    when present even in the heterozygous state,

    was associated with an increased risk of coro-

    nary heart disease in men even after correcting

    for confounding risk factors, she added.

    In diabetic nephropathy, serum adiponectin

    is inversely related to albumin excretion rates

    in individuals with normal albuminuria. How-

    ever, once the state of microalbuminuria or al-

    buminuria is reached, the direction of the rela-

    tionship is changed, with a positive correlation

    observed between serum adiponectin and uri-

    nary albumin concentration (UAC). An inverse

    relationship is also observed between serum

    adiponectin levels and glomerular filtration rate

    (GFR). However, patients with end-stage renal

    failure have serum adiponectin levels as high

    as controls, potentially as a result of a second-

    ary phenomenon. [Kidney Int 2013;83:487-494;

    Nephrol Dial Transplant 2014;doi:10.1093/ndt/

    gfu249] These indicate that levels of serum adi-

    ponectin differ according to phases of nephrop-

    athy. In a prospective study of a small cohort

    with relatively well preserved kidney function

    followed up to 20 months, a low serum adipo-

    nectin level was able to predict progression of

    albuminuria, suggesting that in this selected

    population, adiponectin is indeed protective

    against renal failure, said Lam.

    Fatty liver disease is another complication fre-

    quently seen among T2DM patients. An inverse

    relationship is seen between serum adiponec-

    tin and serum alanine aminotransferase (ALT),

    suggesting a protective effect conferred by the

    protein. The increase in serum adiponectin lev-

    els also correlates to improvements in hepatic

    incidences. [J Clin Invest2003;112:91-100]

    It is now commonly known that T2DM in-

    creases the risk for the development of certain

    types of cancers. These include cancer of the

    pancreas, liver, colorectum, bladder and repro-

    ductive tract. Adiponectin, working through vari-

    ous signaling mechanisms, has been shown to

    decrease cell proliferation in many animal- and

    cell-based studies. In humans, low adiponectin

    levels found in diabetes-related cancer patients

    have been found to have a decreased ability to

    limit proliferation and metastasis. [Endocr Relat

    Cancer 2009;16:1103-1123; Diabetes Care

    2010;33:1674-1685]

    The myriad of studies described show clear

    potential for the manipulation of adiponectin in

    diseased states to create therapeutic remedies.

    Current anti-diabetic and cardiovascular drugs

    such as agonists of peroxisome proliferator-

    activated receptor (PPAR) and statins are as-

    sociated with increased plasma adiponectin in

    humans. The recently discovered fibroblast

    growth factor 21 (FGF21), a metabolic regula-

    tor, is the most potent adiponectin stimulator to

    date, said Lam. Many pharmaceutical com-

    panies are now developing FGF21 mimetics

    or analogues to improve the activity as well as

    the circulating half-life of FGF21. All these are in

    various stages of clinical trials, one of which has

    already been used in a phase II clinical trial in

    humans, she added.

    Lam also briefly spoke of the importance

    of lifestyle measures in improving adiponectin

    levels, stating that a low-energy Mediterranean

    diet, combined with increased physical activ-

    ity, has shown to increase adiponectin levels by

    30 percent over 2 years in individuals who suc-

    ceeded in losing weight. [JAMA2003; 289:1799-

    1804]

    Metformin is commonly used to treat type 2diabetes mellitus (T2DM), but it may haveother benefits, says a prominent specialist.

    In recent years, metformin has been suggest-

    ed to have beneficial effects in type 1 diabetes

    mellitus (T1DM), heart failure (HF) and cancer,

    said Professor Andrew Morris, vice principal,

    data science, School of Molecular, Genetic and

    Population Health Sciences, University of Edin-

    burgh, UK.

    A systemic review of 197 clinical trials showed

    that prescribing metformin on top of insulin ther-

    apy to patients with T1DM reduces insulin-dose

    requirement. Metformin was also linked to reduc-

    tions in HbA1c, weight and total cholesterol. Still,

    it is not conclusive whether these benefits last

    more than a year and if there is any additional car-

    dioprotective benefit. [Diabetologia2010;53:809-

    820]

    Currently, there are 24 clinical trials investigat-

    ing the effects of metformin on HF, said Morris.

    Examples of older studies that have demonstrat-

    ed the cardioprotective benefit of metformin are,

    for one, a Canadian study that ran from 1991 to

    1996. The study analyzed the data of patients re-

    ceiving oral anti-diabetic therapies from the Sas-

    katchewan Health database. The researchers

    found that metformin monotherapy or in com-

    bination with sulfonylurea were associated with

    improved mortality rates in patients with diabetes

    and HF compared with sulfonylurea monothera-

    py alone. [Diabetes Care 2005;28:2345-2351]

    Another study alluding to metformins cardio-

    protective benefit utilized information from the

    Diabetes Audit and Research in Tayside Scot-

    land (DARTS) database. The study included

    diabetic patients who had a history of conges-

    tive heart failure (CHF) and were prescribed oral

    antidiabetic agents, but not insulin. The findings

    concluded that metformin may lower the risk of

    death in patients with CHF and DM when used

    as monotherapy or in combination with sulfonyl-

    urea. [Am J Cardio2010;106:1006-1010]

    There is also the link between metformin and

    cancer to be explored further. Metformin activates

    AMP-activated protein kinase (AMPK) in hepato-

    cytes, which leads to reduced hepatic glucose

    production and increased glucose utilization. An-

    drew said there is new insight into the function

    of AMPK. As LKB1 is an upstream regulator of

    AMPK and a known tumor suppressor, metformin

    may be able to lower cell turnover and protein

    synthesis. [J Biol2003;2:28] He said that based

    on data from clinicaltrials.gov, there are currently

    214 studies on metformin and cancer patients.

    As Morris said, We are only at the beginning.

    As the understanding of how metformin works

    improves, so will the quality of treatment.
