MedicalResearch.com Interview with: Professor Keith A. Wesnes BSc PhD FSS CPsychol FBPsS Head Honcho, Wesnes Cognition Ltd Professor of Cognitive Neuroscience, Medical School, University of Exeter, UK Visiting Professor, Department of Psychology Northumbria University, Newcastle, UK Adjunct Professor, Centre for Human Psychopharmacology, Swinburne University, Melbourne, Australia Visiting Professor, Medicinal Plant Research Group Newcastle University, UK Wesnes Cognition Ltd, Little Paddock, Streatley Hill, Streatley on Thames UK  MedicalResearch.com: What is the background for this study? What are the main findings? Response: This data we reported were taken from the PROTECT study, a 10-year research programme being conducted jointly by Kings College London and the University of Exeter Medical School. It started in November 2015 and over 20,000 individuals aged 50 to 96 years have enrolled. A highly novel feature of the study is that it is run entirely remotely, the participants logging on via the internet at home and providing demographic and life style information, and also performing online cognitive tasks of key aspects of cognitive function. The tasks are from two well-validated systems, CogTrack and the PROTECT test system, and assess major aspects of cognitive function including focused and sustained attention, information processing, reasoning and a range of aspects of memory. One of the lifestyle questions was ‘How frequently do you engage in word puzzles, e.g. crosswords?’ and the 6 possible answers were: never; occasionally; monthly; weekly; daily; more than once per day. We analysed the cognitive data from 17,677 individuals who had answered the question, and found that the more often the participants reported engaging in such puzzles, the better their cognitive function on each of the 9 cognitive tasks they performed. The group who never performed such puzzles were poorest on all measures, and the improvements were mostly incremental as the frequency of use increased. The findings were highly statistically reliable, and we controlled for factors including age, gender and education. To evaluate the magnitudes of these benefits, we calculated the average decline over the age-range on the various tasks in the study population. The average difference between those who ‘never’ did puzzles to those who did so ‘more than once a day’ was equivalent to 11 years of ageing; and between those who never did puzzles and all those who did was 8 years.

MedicalResearch.com Interview with: Eralda Asllanaj Department of Epidemiology Erasmus University Medical Center Rotterdamthe Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is known that women with early onset of menopause (age below 45 years) have an increased risk of cardiovascular disease and overall mortality. This increased risk is thought to be due to the adverse effects of menopause on cardiovascular risk factors. Type 2 diabetes is a major risk factor for cardiovascular disease, but it remains unclear whether age at menopause affects the risk of developing type 2 diabetes. Our study shows that women who experience menopause before the age of 40 were almost 4 times more likely to develop type 2 diabetes than those experiencing menopause after 55 years old. Moreover, those who had menopause between 40 to 44 years were 2.4 times more likely to have diabetes later in life. The risk of having diabetes reduced by 4 % per year older the women experienced menopause. Adjustment for the various confounding factors and differences in genetic predisposition to early menopause did not affect the results.

Author Interviews, BMJ, Exercise - Fitness, OBGYNE, Weight Research / 20.07.2017

MedicalResearch.com Interview with: Shakila Thangaratinam Professor of Maternal and Perinatal Health Joint Director of BARC (Barts Research Centre for Women's Health) Women's Health Research Unit | Multidisciplinary Evidence Synthesis Hub (MESH) Barts and the London School of Medicine and Dentistry R & D Director for Women's Health Queen Mary University of London  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Pregnant women who are overweight or obese, or who gain excess weight gain in pregnancy are at high risk of complications. We wanted to find
  1. If healthy diet and physical activity in pregnancy reduced weight gain, and improved outcomes for the mother and baby
  2. If the effects of the interventions differed according to the characteristics of the mother such as body mass index, parity, ethnicity, and underlying medical condition
We established a network (International Weight Management in Pregnancy i-WIP) of researchers from 16 countries, and 41 institutions to answer the above. We found that women who followed a healthy diet and moderate physical activity gained less weight in pregnancy than other women; this beneficial effect was observed irrespective of mother's body mass index, parity, ethnicity, and underlying medical condition. Diet and physical activity in pregnancy has a beneficial effect on weight gain in pregnancy, and lowers the odds of caesarean section, and gestational diabetes. (more…)

Author Interviews, Brigham & Women's - Harvard, Heart Disease, JAMA, Pediatrics / 19.07.2017

MedicalResearch.com Interview with: Holly Gooding, MD, MSc Assistant Professor of Medicine and Pediatrics Harvard Medical School Division of Adolescent/Young Adult Medicine Boston Children's Hospital Division of General Internal Medicine Brigham and Women's Hospital Boston, MA MedicalResearch.com: What is the background for this study? What are the main findings? Response: Dr Stephanie Chiuve and colleagues at the Harvard TH Chan School of Public Health developed the Healthy Heart Score to predict the risk of heart disease in older adults based on lifestyle factors measured in middle age. We have known for some time that the precursor to heart disease – known as atherosclerosis – actually starts in childhood and adolescence. We calculated the Healthy Heart Score for young adults ages 18-30 years old and found it works in this age group as well.

MedicalResearch.com Interview with: Yan Zheng Research Fellow, Department of Nutrition Harvard T.H. Chan School of Public HealthYan Zheng Research Fellow, Department of Nutrition Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Most people gain weight cumulatively during young and middle adulthood. Because the amount of weight gain per year may be relatively small, it may go unnoticed by individuals and their doctors—but the cumulative weight gain during adulthood may eventually lead to obesity over time. Compared to studies of attained body weight or BMI, the investigation of weight change may better capture the effect of excess body fat because it factors in individual differences in frame size and lean mass.

Author Interviews, Baylor College of Medicine Houston, Biomarkers, Brain Cancer - Brain Tumors, Cancer Research, PNAS / 19.07.2017

MedicalResearch.com Interview with: Chonghui Cheng, M.D., Ph.D. Associate Professor Department of Molecular & Human Genetics Lester & Sue Smith Breast Center Baylor College of Medicine Houston, TX77030 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Understanding the mechanisms that give cancer cells the ability to survive and grow opens the possibility of developing improved treatments to control or cure disease. In the case of glioblastoma multiforme, the deadliest type of brain cancer, abnormal EGFR signaling is frequently observed. Treatment with the EGFR inhibitor erlotinib attempts to kill cancer cells. However, the clinical benefit of treatment with this and other EGFR inhibitors has been limited by the development of drug resistance. Scientists at Baylor College of Medicine discovered that the molecule CD44s seems to give cancer cells a survival advantage. Eliminating this advantage by reducing the amount of CD44s resulted in cancer cells being more sensitive to the deadly effects of the drug erlotinib. (more…)
Author Interviews, OBGYNE, Pediatrics / 19.07.2017

MedicalResearch.com Interview with: Francesca Volpe Psy.D and Prof. Vincenzo Zanardo Division of Perinatal Medicine, Policlinico Abano Terme Abano Terme, ItalyFrancesca Volpe Psy.D and Prof. Vincenzo Zanardo Division of Perinatal Medicine, Policlinico Abano Terme Abano Terme, Italy MedicalResearch.com: What is the background for this study? What are the main findings? Response: Newborn infants, placed skin-to-skin on their mother’s chest instinctively have the ability to crawl to their mother’s breast, exploring with their hands and massaging the breast to support the first feed.  Left undisturbed, the infant will make several attempts until it finds and latches onto the nipple and begins to nurse. What leads mammalian infants who are placed on their mothers’ chests to seek out, without any assistance, the nipple and to attach themselves to it to nurse is not fully understood. When we turned our attention to the thermal properties of the female’s nipple-areolar complex (NAC) in lactating mothers soon after birth, we found that it had a higher temperature and pH value and lower elasticity with respect to the surrounding breast skin. We hypothesised that the higher temperature could help the newborn infant to locate the nipple and to latch onto it, leading to the first sucking experience.  In addition, the diffusion of odorous molecules is presumably enhanced by the relatively high surface temperature of the areola in view of the rich supply of blood capillaries that irrigate the region. There is, in fact, some scientific evidence that show that infants respond to the odours released by the breasts of lactating women; breast odours, which are enhanced by the skin’s greater warmth, are another factor that facilitates breastfeeding by helping the infant to recognize its mother participating in the mother-to-infant bonding.

Alzheimer's - Dementia, Author Interviews, Radiology / 18.07.2017

MedicalResearch.com Interview with: Liana Apostolova, MD, MSc, FAAN Barbara and Peer Baekgaard Professor  in Alzheimer's Disease Research Professor in Neurology, Radiology. Medical and Molecular Genetics Indiana University School of Medicine Indiana Alzheimer's Disease Center Indianapolis, IN 46202 MedicalResearch.com: What is the background for this study? Response: While many studies have evaluated the diagnostic or prognostic implications associated with amyloid PET, few have explored its effects on the patient or caregiver. Amyloid imaging does not only help clinicians with their diagnosis and management. It also affects patient and caregiver decisions related to lifestyle, financial and long-term care planning, and at times also employment. Few studies to date have explored patient and caregiver views on the clinical use of amyloid PET and the potential benefits they could derive from having more precise diagnosis. (more…)

MedicalResearch.com Interview with: Douglas W. Scharre MD Professor of Clinical Neurology and Psychiatry Director, Division of Cognitive Neurology Department of Neurology Director, Center for Cognitive and Memory Disorders Director, Memory Disorders Research Center Co-Director, Neuroscience Research Institute Ohio State University Wexner Medical Center Columbus, OH   MedicalResearch.com: What is the background for this study? What are the main findings? Response: Self-Administered Gerocognitive Examination (SAGE) is a pen-and paper, valid and reliable cognitive assessment tool for identifying individuals with mild cognitive impairment (MCI) or early dementia. We published age and education normative data on SAGE and determined that one point be added to the scores when age over 79 and one point be added when education level is 12 years or less. We evaluated the identical test questions in digital format (eSAGE) made for tablet use, adjusted with previously published age and education norms, and determined eSAGE’s association with gold standard clinical assessments. eSAGE is commercially known as BrainTest.

Author Interviews, Boehringer Ingelheim, Heart Disease, JAMA / 18.07.2017

MedicalResearch.com Interview with: Javed Butler, MD, PhD Chief of the Cardiology Division Dr. Vincent Yang, Simons Chair in Internal Medicine Stony Brook University  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Persistent congestion is associated with worse outcomes in acute heart failure (AHF). Mineralocorticoid receptor antagonists at high doses may relieve congestion, overcome diuretic resistance, and mitigate the effects of adverse neurohormonal activation in AHF. We therefore studies high dose spironolactone in patients with AHF. Unfortunately all of our primary and secondary endpoints were not different between spironolactone and placebo arms. (more…)

MedicalResearch.com Interview with: Stephen R. Russell, MD Dina J Schrage Professor of Macular Degeneration Research Service Director, Vitreoretinal Diseases and Surgery Professor of Ophthalmology and Visual Sciences The University of Iowa MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study examines the efficacy (and safety) of treating children and adults with a form of retinitis pigmentosa known as RPE65-associated Lebers congenital amaurosis, with an adeno-associated viral vector(AAV) delivered RPE65 construct.  Building on successful phase 1/2b trials from multiple centers, the AAV-hRPE65v2 agent now designated as voretigene neparvovec, contains a highly optimized enhancing sequence and promoter. The main findings were an improvement on a multiple light level mobility test (MLMT) and multiple additional supportive secondary endpoints which included improvements in full-field light sensitivity, Goldmann visual field, and others.

MedicalResearch.com Interview with: Donal J. Sexton, BSc, MD The Irish Longitudinal Study on Ageing Trinity College Dublin Health Research Board Clinical Research Facility Galway National University of Ireland Galway, Galway, Ireland Trinity Health Kidney Centre, Tallaght Hospital Department of Nephrology, Beaumont Hospital, Royal College of Surgeons of Ireland Dublin, Ireland MedicalResearch.com: What is the background for this study? What are the main findings? Response: In this study we used the inclusion criteria for SPRINT to identify those community dwelling elders who would meet criteria for the trial in clinical practice. Our data are based on a prospective cohort study composed of participants chosen by a national stratified random sampling mechanism. If SPRINT participants were truly representative of the population, then the participants in the standard care arm of the trial should resemble the population to some extent. If this were true then the injurious falls rate might be similar between the two samples also. (more…)
Author Interviews, JAMA, Opiods, Pain Research, Primary Care / 17.07.2017

MedicalResearch.com Interview with: Jane M. Liebschutz, MD, MPH Associate Professor of Medicine Section of General Internal Medicine Boston University School of Medicine Boston, Massachusetts MedicalResearch.com: What is the background for this study? Response: The number of patients receiving opioids for chronic pain has risen over the past 2 decades in the US, in parallel with an increase in opioid use disorder. The CDC and professional medical societies have created clinical guidelines to improve the safety of opioid prescribing, yet individual prescribers can find them onerous to implement. We developed an intervention to change clinical practice to support primary care physicians who prescribe the majority of opioids for chronic pain. The intervention included 4 elements- a nurse care manager to help assess, educate and monitor patients, an electronic registry to keep track of patient data and produce physician level reports, an individualized educational session for the physician by an opioid prescribing expert based on the physician-specific practice information and online resources to help with decision-making for opioid prescribing (www.mytopcare.org). We tested whether the intervention would improve adherence to guidelines, decrease opioid doses and decrease early refills, as a marker of potential prescription opioid misuse among 985 patients of 53 primary care clinicians in four primary care practices.

Addiction, Alcohol, Author Interviews, NIH / 17.07.2017

MedicalResearch.com Interview with: Lorenzo Leggio, M.D., Ph.D. Chief of the Section on Clinical Psychoneuroendocrinology and Neuropsychopharmacology, a NIAAA intramural laboratory MedicalResearch.com: What is the background for this study? MedicalResearch.com: What is the background for this study? What are the main findings? Response: Aldosterone is an important hormone involved in the control of blood pressure and electrolytes via its mineralcorticoid receptor (MR). In addition to its roles in the periphery in our body, aldosterone also acts on the brain where the MR is particularly present in regions like the amygdala. The amygdala plays an important role in stress, anxiety and excessive alcohol drinking. Back in 2008, we conducted a small pilot study where we found that alcohol-dependent patients with higher blood aldosterone concentrations have higher alcohol craving. (more…)
AHA Journals, Author Interviews, Stroke, Weight Research / 17.07.2017

MedicalResearch.com Interview with: Hugo J. Aparicio, MD, MPH Assistant Professor Vascular Neurology, Department of Neurology Investigator, The Framingham Heart Study www.framinghamheartstudy.org Boston University School of Medicine Boston, MA 02118-2526 MedicalResearch.com: What is the background for this study? Response: The association of body weight with survival after stroke has been studied before and is a controversial topic. Results have varied between studies and have often been contradictory. The observational findings that carrying extra weight can be protective after having a disease, like stroke or heart attack, has been called an obesity paradox, since obesity in itself is a risk factor for cardiovascular disease and mortality in the general population. Stroke research has focused on hospitalized stroke patients with weight measured at the time of the stroke. BMI is often missing in this group of patients, especially when a stroke is severe or the patients cannot report their weight. In the FHS we have data regarding weight prior to stroke, obtained during regularly scheduled research exams, with multiple data points on body weight and vascular risk factors over time. All before the stroke occurs. And have also compared survival outcomes with a group of control participants, those without stroke, to see if the so-called ‘obesity paradox’ is a non-specific finding seen in older adults or seen specifically in stroke patients.

Author Interviews, CDC, OBGYNE, Pediatrics, Race/Ethnic Diversity / 17.07.2017

MedicalResearch.com Interview with: Dr. Erica H. Anstey PhD Division of Nutrition, Physical Activity and Obesity National Center for Chronic Disease Prevention and Health Promotion Immunization Services Division National Center for Immunization and Respiratory Diseases CDC MedicalResearch.com: What is the background for this study? Response: The American Academy of Pediatrics (AAP) recommends that infants are breastfed exclusively for about the first 6 months and that breastfeeding continue for at least 12 months, and thereafter for as long as mother and baby desire. Although breastfeeding initiation and duration rates have increased overall in the United States, breastfeeding rates vary by geographic location, socioeconomic, and race/ethnic groups. Breastfeeding initiation and duration have been historically and consistently lower among black infants compared with white and Hispanic infants. There are many factors that influence a woman’s decision to start and continue breastfeeding. These include knowledge about breastfeeding, cultural and social norms, family and social support, and work and childcare environments. Some barriers to breastfeeding are disproportionately experienced by black women, including earlier return to work, inadequate receipt of breastfeeding information from providers, and lack of access to professional breastfeeding support.

Artificial Sweeteners, Author Interviews, CMAJ, Heart Disease, Weight Research / 17.07.2017

MedicalResearch.com Interview with: Meghan Azad PhD Assistant Professor, Department of Pediatrics & Child Health and Community Health Sciences, University of Manitoba; Associate Investigator, Canadian Healthy Infant Longitudinal Development (CHILD) Study Research Scientist, Children’s Hospital Research Institute of Manitoba; co-Lead, Population Health Pillar, Developmental Origins of Chronic Diseases in Children Network MedicalResearch.com: What is the background for this study? Response: Consumption of artificial sweeteners, such as aspartame, sucralose and stevia, is widespread and increasing.  Emerging data indicate that artificial, or non-nutritive, sweeteners may have negative effects on metabolism, gut bacteria and appetite, although the evidence is conflicting. MedicalResearch.com: What are the main findings? Response: We conducted a systematic review of 37 studies that collectively followed over 400,000 people for an average of 10 years. Only 7 of these studies were randomized clinical trials (the gold standard in clinical research), involving 1003 people followed for 6 months on average. The trials did not show a consistent effect of artificial sweeteners on weight loss, and the longer observational studies showed a link between consumption of artificial sweeteners and relatively higher risks of weight gain and obesity, high blood pressure, diabetes, heart disease and other health issues.

Author Interviews, Pediatrics, Primary Care, Vaccine Studies / 14.07.2017

  MedicalResearch.com Interview with: S. Hughes Melton, MD, MBA, FAAFP AAFP Foundation president MedicalResearch: What is the background for this initiative? What are the main vaccinations that teens should have?  Response: The Centers for Disease Control and Prevention (CDC) recommends adolescents receive four immunizations – two of which are administered as multi-dose series – to help protect against meningococcal meningitis caused by serogroups A, C, W and Y; human papillomavirus (HPV); tetanus, diphtheria and pertussis (Tdap); and influenza (flu).1 Despite these recommendations, millions of teens remain vulnerable to serious infectious disease.2,3 Family physicians are well equipped to immunize their patients against a host of common infectious diseases and improve public health. However, discussing teen vaccinations during annual appointments may present challenges due to other issues teens and their parents/guardians may be focused on at this age. The American Academy of Family Physicians Foundation (AAFP Foundation) launched Highlight on VACCINATIONS 4 TEENS to help remind family physicians and their care teams to make immunization a priority at these key appointments for teens.

Author Interviews, Dental Research, Microbiome, University of Pennsylvania / 14.07.2017

MedicalResearch.com Interview with: Dana T. Graves DDS Department of Periodontics School of Dental Medicine University of Pennsylvania Philadelphia, PA MedicalResearch.com: What is the background for this study? What are the main findings? Response: It was previously thought that diabetes did not have a significant effect on oral bacteria. We found that diabetes caused a change in the composition of the oral bacteria. This change caused resulted in a bacterial composition that was more pathogenic and stimulated more inflammation in the gums and greater loss of bone around the teeth. (more…)
Author Interviews, Dermatology, Immunotherapy, JAMA, Lung Cancer / 14.07.2017

MedicalResearch.com Interview with: Dr. Noelia Rivera MD Dermatologist Hospital Universitari Germans Trias i Pujol, Badalona Universitat Autònoma de Barcelona MedicalResearch.com: What is the background for this study? Response: In the last few years some new therapies targeting immune checkpoints have been developed. The programmed death receptor-1 (PD-1) are immune checkpoints that prevent the immune system to act against own tissues. By blocking these mediators it is possible to prevent tumors to escape from the immune system. About half of the patients receiving these therapies will develop mild to moderate cutaneous adverse events. In the pre-authorization studies for malignant melanoma these include rash, vitiligo, and pruritus. "Rash" has commonly been reported as an adverse event in many oncologic trials evaluating the drugs, without providing further information about the clinical or histological details. Lately, lichenoid eruptions associated to these therapies have been reported and it suggests that an important percentage of these reactions present lichenoid histological features. (more…)
Author Interviews, Technology / 14.07.2017

MedicalResearch.com Interview with: Dr Ian Williams PhD Associate Professor, DMT Lab Birmingham City University Faculty of Computing, Engineering and the Built Environment Centre for Digital Media Technology Millennium Point Birmingham UK MedicalResearch.com: What is the background for your work? Response: Our work at the DMT Lab (dmtlab.bcu.ac.uk) focuses on developing a novel Mixed Reality (MR) medical presentation platform which allows practitioners to interact with patient data and virtual anatomical models in real time. The system enables the presentation of medical data, models and procedures to patients with the aim of educating them on pending procedures or the effects of lifestyle choices (for example the effects of smoking or excessive alcohol consumption). The system employs an exocentric mixed reality environment which can be deployed in any room. It integrates a medical practitioner in real time with multimodal patient data and the corresponding result is a real time co-located visualisation of both the practitioner and the data, which they can interact with in real time.  We implement a natural interaction method into the system which improves a user’s level of direct interaction with the virtual models and provides a more realistic control of the data. The system can also be used in a fun educational setting where patients, students, children or any naive user, can learn about medical anatomical information via a real-time interactive mixed reality “body scanner”. This fun system overlays the MR information onto their own body in real-time and shows them scaled and interactive virtual organs, anatomy and corresponding medical information. We are aiming for this system to be used not only in patient education but also in engaging and informing people on lifestyle choices. (more…)
Author Interviews / 14.07.2017

MedicalResearch.com Interview with: Matthew R. McGrail, PhD Monash University School of Rural Health Churchill, Victoria Australia MedicalResearch.com: What is the background for this study? Response: Rural populations continue to experience relative shortages of the supply of primary care physicians, with associated links to poorer health. Although considerable research has identified factors that facilitate or impede supply of physicians in rural areas, macro-level empirical evidence of observed rural mobility of physicians - notably, which are more likely to move and why - is limited. Improved understanding of mobility and nonretention of rural physicians is important because of its impact on training and workforce policy, and resultant physician supply to both the origin area (ie, the location from which the physician moved) and to the destination area (ie, the location to which the physician has moved). The cost of mobility and staff turnover can be large, both in direct costs but also in terms of service quality and continuity to the community. In our study, we aimed to describe the geographic mobility patterns of rural primary care physicians. This evidence will provide stronger understanding of the factors behind the observed mobility and nonretention of rural primary care physicians. (more…)
Author Interviews, Autism, Gastrointestinal Disease, Nutrition / 14.07.2017

MedicalResearch.com Interview with: Bradley James Ferguson, PhD University of Missouri School of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Many individuals with autism spectrum disorder (ASD) have gastrointestinal problems, such as constipation, irritable bowel syndrome and abdominal pain, but the cause of these GI issues is not currently known. Previous research from our laboratory showed a significant positive relationship between cortisol levels and GI problems, especially for constipation. However, it is possible that other factors such as diet may affect GI functioning, especially since many children have altered diets. This study examined 32 different nutrients in the children’s diets, as assessed by a food frequency questionnaire that assessed the participant’s diet over the past month, and how each nutrient was related to upper and lower GI tract symptom scores over the past month created from the Questionnaire on Pediatric Gastrointestinal Symptoms – Rome III. The results showed no significant relationships between any of the nutrients and GI symptoms, suggesting that diet was not associated with GI symptoms in this sample. (more…)
Author Interviews, Dermatology, Melanoma / 14.07.2017

MedicalResearch.com Interview with: Maryam M. Asgari, MD, MPH Department of Dermatology Massachusetts General Hospital, Department of Population Medicine Harvard Medical School, Boston, Massachusetts Division of Research, Kaiser Permanente Northern California, Oakland  MedicalResearch.com: What is the background for this study? What are the main findings? Response:  Laboratory studies show lithium, an activator of  the Wnt/ß-catenin signaling pathway, slows melanoma progression, but no published epidemiologic studies have explored this association. We conducted a retrospective cohort study of adult white Kaiser Permanente Northern California members (n=2,213,848) from 1997-2012 to examine the association between lithium use and melanoma risk. Our main finding is that lithium-exposed individuals had a reduced incidence of melanoma, did not develop very thick tumors (> 4 mm Breslow depth) or extensive disease at presentation, and had decreased melanoma-specific mortality compared to unexposed individuals suggesting a possible role for lithium in altering melanoma risk.

Author Interviews, Brigham & Women's - Harvard, Cancer Research, Dermatology, HIV, JAMA, Kaiser Permanente, Merck / 13.07.2017

MedicalResearch.com Interview with: Maryam M. Asgari, MD, MPH Department of Dermatology Massachusetts General Hospital, Department of Population Medicine Harvard Medical School, Boston, Massachusetts Division of Research, Kaiser Permanente Northern California, Oakland MedicalResearch.com: What is the background for this study? What are the main findings? Response: Nonmelanoma skin cancer – defined as basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) – is a common malignant condition, affecting more than 2 million Americans every year. BCCs are more common than SCCs among individuals with healthy immune systems, while SCCs are more predominate than BCCs among people who are immunocompromised. We examined how laboratory markers used to evaluate HIV disease progression may be associated with subsequent nonmelanoma skin cancer risk in white patients previously diagnosed with at least one such cancer from 1996 to 2008.  We measured CD4 count, viral load and subsequent nonmelanoma skin cancer. The study included 455 participants with HIV and 1,952 without HIV. All were members of the Kaiser Permanente Northern California health care plan. (more…)
