OBJECTIVES: It is not clear whether being overweight or obese influences postoperative complications in myasthenia gravis (MG) patients. We retrospectively investigated an association between body mass index (BMI) and postoperative complications in MG. MATERIALS AND METHODS: Fifty-nine MG patients who had undergone transsternal thymectomy were classified as low or high BMI based on the criteria for Asian-Pacific populations. An association between BMI and complications was analyzed...

BACKGROUND: Women with higher serum calcium may be more likely to be diagnosed and die of ovarian cancer. We evaluated that finding in a large, prospective cohort. METHODS: We conducted a nested case-control study using a population-based biobank from Norway. We compared 202 ovarian cancer cases and 202 controls, matched for age, date at blood draw, and county of residence, with respect to serum calcium and albumin, adjusted for anthropometric variables. We evaluated risks using the entire follow-up period as well as 2-15 years and 16-25 years ("early" and "late", respectively)...

Interspecific hybridization and genetic introgression are commonly observed in natural populations of many species, especially trees. Among oaks, gene flow between closely-related species has been well documented. And yet, hybridization does not lead to a 'melting pot', i.e. the homogenization of phenotypic traits. Here, we explore how the combination of several common reproductive traits and genomic biology could create an avenue for interspecific gene flow that partially explains this apparent paradox. During meiosis, F<sub>1</sub> hybrids will produce approximately (½)<sup>n</sup> 'reconstructed' parental gametes, where n equals the number of chromosomes...

Māori, the indigenous people of New Zealand, experience disproportionate rates of stomach cancer, compared to non-Māori. The overall aim of the study was to better understand the reasons for the considerable excess of stomach cancer in Māori and to identify priorities for prevention. Māori stomach cancer cases from the New Zealand Cancer Registry between 1 February 2009 and 31 October 2013 and Māori controls, randomly selected from the New Zealand electoral roll were matched by 5-year age bands to cases...

INTRODUCTION: In sub-Saharan Africa, approximately 100 million people have CKD, yet genetic risk factors are not well-understood. Despite the potential importance of understanding APOL1 risk allele status among individuals with CKD, little genetic research has been conducted. Therefore, we conducted a pilot study evaluating the feasibility of and willingness to participate in genetic research on kidney disease, and we estimated APOL1 risk allele frequencies among individuals with CKD...

Fetal growth restriction in early pregnancy increases the risk of adverse pregnancy outcome, which has a significant social and psychological impact on women. There is limited information related to community-based study to evaluate early indicators related to miscarriage. The aim of this study is to examine the relationship between fetal growth restriction, measured by ultrasound crown-rump length (CRL), and subsequent occurrence of miscarriage in pregnant women in rural Bangladesh. The study was conducted within the Maternal and Infant Nutrition Interventions Trial in Matlab (MINIMat study), Bangladesh...

BACKGROUND: We have previously shown that TNFα and IL-1β differentially regulate the inflammatory phenotype of human brain endothelial cells (hCMVECs). In this regard, IL-1β treatment was considerably more potent than TNFα at increasing expression of inflammatory chemokines and leukocyte adhesion molecules. We therefore hypothesised that interaction of the hCMVECs with human monocytes would also be dependent on the activation status of the endothelium. Therefore, the primary aim of this study was to assess whether brain endothelial cells activated by IL-1β or TNFα differed in their interaction with monocytes...

BACKGROUND: Although excessive alcohol-related mortality in the post-Soviet countries remains the major public health threat, determinants of this phenomenon are still poorly understood. AIMS: We assess simultaneously individual- and area-level factors associated with an elevated risk of alcohol-related mortality among Lithuanian males aged 30-64. METHODS: Our analysis is based on a census-linked dataset containing information on individual- and area-level characteristics and death events which occurred between March 1st, 2011 and December 31st, 2013...

There is increasing awareness of the special needs for care of the elderly cancer patient. Newer precise conformal radiotherapy techniques allow the safe delivery of higher doses of radiotherapy to the target tumor while reducing the dose to surrounding critical organs. This has led to a shortening of radiotherapy protocols for both curative and palliative indications. We review these novel techniques and protocols and the published clinical studies that include elderly patients treated with these techniques...

PURPOSE: Tube exposure remains one of the most common complications after glaucoma drainage device (GDD) implantation, despite various types of patch grafts available today. We present a 4 patient case series following the effectivity of the keratolimbal allograft (KLAL) as a patch graft for cases of tube exposure. Given its inherent population of stem cells, our hypothesis was that this highly replicative, biological tissue would provide an adequate means of glaucoma tube coverage. The subset of patients chosen for the KLAL patch graft all had a history of abnormally scarred conjunctiva or thin sclera...

PURPOSE: The purpose of this is to test the hypothesis the intraocular pressure (IOP) peaks during a stress test [the water drinking test (WDT)] can estimate the risk of future visual field progression in treated primary open-angle glaucoma (POAG) patients. PATIENTS AND METHODS: Design: Prospective, longitudinal study. SETTING: Clinical practice. STUDY POPULATION: Treated POAG patients whose IOP was ≤18 mm Hg and who had no IOP-lowering interventions between the date of the WDT and the last eligible visual field...

BACKGROUND: Iraqi-born immigrants residing in Sweden are at high risk for type 2 diabetes, obesity and hyperlipidemia compared with native Swedes. Paradoxically, hypertension is less prevalent in this immigrant population. The aim of this study was to investigate differences in renal function and further if differences in blood pressure (BP) levels were associated with differences across ethnicities in renal function as a possible explanation to the paradox. METHODS: A population-based, cross-sectional study of men and women, born in Iraq or Sweden, aged 30-75 years was conducted in Malmö, Sweden, from 2010 to 2012...

Major depression disorder (MDD) is a complex neuropsychiatric disorder and an increasing number of genetic risk variants are being identified. Investigation of their influence in the general population requires accurate and efficient assessment of depressive symptoms. Here, clinical interviews conducted by clinicians are the gold standard. We investigated whether valid and reliable clinical phenotypes can be obtained efficiently using self-administered instruments. Lifetime depressive symptoms and lifetime MDD diagnosis were assessed in 464 population-based individuals using a clinical interview and a structured, self-administered checklist...

BACKGROUND: Despite the importance of estimating population level cancer outcomes, most registries do not collect critical events such as relapse. Attempts to use health administrative data to identify these events have focused on older adults and have been mostly unsuccessful. We developed and tested administrative data-based algorithms in a population-based cohort of adolescents and young adults with cancer. METHODS: We identified all Ontario adolescents and young adults 15-21 years old diagnosed with leukemia, lymphoma, sarcoma, or testicular cancer between 1992-2012...

Suitably designed experiments offer the possibility of quantifying evolutionary convergence because the fraction of replicate populations that converge is known. Here I review an experiment with Escherichia coli, in which 12 populations were founded from the same ancestral strain and have evolved for almost 30 years and more than 65,000 generations under the same conditions. The tension between divergence and convergence has been a major focus of this experiment. I summarize analyses of competitive fitness, correlated responses to different environments, cell morphology, the capacity to use a previously untapped resource, mutation rates, genomic changes, and within-population polymorphisms...

Although eradication of hepatitis C virus (HCV) decreases the risk of hepatocellular carcinoma (HCC) development, a considerable level of risk remains in cirrhotic patients with advanced liver disease. Yet, data for the effect of serum markers on HCC development in this population after viral eradication are still lacking. Seventy-eight consecutive patients with HCV infection and decompensated cirrhosis were administered interferon-based regimens at our hospital between August 2008 and December 2013. Thirty-four achieved sustained virological response and were enrolled in the study...

In the U.S. general population, incidence of colorectal cancer appears to be increasing in younger age groups since the mid-1980s. The objective of this report was to better understand the time-varying elements (age, period, and birth cohort effects) in the epidemiology of colorectal cancer among the active component of the U.S. Armed Forces. During 1997-2016, there were 1,108 incident cases of colorectal cancer among service members aged 20-59 years, corresponding to an overall incidence rate of 4.3 per 100,000 person-years (p-yrs)...

AIM: To determine the relative validity of a 2-day 24-hour dietary recall (HR) designed to assess energy and nutrient intake among Chinese adults compared with a 2-day weighed dietary record (WD). METHODS: Data were obtained from an ongoing population-based, prospective cohort study of adults aged 18-65 years in South China. A total of 41 adults completing a HR and a WD within 14 days were included in the present analysis. Estimations of individual mean differences, Spearman's correlation coefficients, cross-classifications and Bland-Altman plots were used to assess the agreement between the intakes of energy and 18 nutrients obtained from the HR and the WD...

AIM: Providing effective weight management services to the growing number of overweight or obese hospital patients necessitates long-term service provision; however, it is arguably not within the acute-care hospital remit to provide such extended services. Referral to community-based programs is required to provide continuing weight management services. The Get Healthy Service is a free six-month, telephone-delivered lifestyle program, now offered in several states of Australia with potential for wide population reach...
