Abstract
BACKGROUND Obesity and major depressive disorder (MDD) independently contribute to memory impairment. Little is known about shared neural mechanisms that may result in the cognitive impairment experienced by these populations. This study's aim was to determine how obesity impacts neural activity during a verbal recognition memory task in individuals both with and without MDD. METHODS Functional magnetic resonance imaging was employed to examine whether differences in neural activation patterns would be seen across three groups during the Warrington's Recognition Memory Test. Three study groups are reported: 20 subjects with obesity but without MDD (bariatric controls), 23 subjects with past or current MDD and obesity, and 20 normal BMI controls (healthy controls). RESULTS Three-group conjunction analyses indicated that overlapping neural regions were activated during both encoding and retrieval processes across all groups. However, second-level 2-group t-contrasts indicated that neural activation patterns differed when comparing healthy and bariatric controls, and when comparing bariatric controls and bariatric MDD participants. DISCUSSION Results indicate that obesity in conjunction with MDD confers a subtle impact on neural functioning. Given high rates of obesity and MDD comorbidity, and the role of cognition on ability to return to premorbid level of functioning, this association should inform treatment decisions.

Abstract
AIM The associations of body mass index (BMI) and serum lipids with cognitive function are inconsistent and remain unclear, especially in the elderly population. This discrepancy triggered our interest in exploring the impact of BMI and serum lipids on memory status among the elderly Chinese population. METHODS Data were collected from the China Health and Nutrition Survey database. We used data from the survey's 2015 wave to examine the association between BMI and memory status and from the 2009-2015 surveys to examine the association between serum lipids and cognitive function. We performed multivariable logistic regression analyses and multivariable linear regression analyses to examine these associations. RESULTS Being underweight, normal weight, and severely obese were associated with an increased risk of bad self-reported memory status, with overweight as the reference. After adjustment for confounding factors, BMI was positively associated with cognitive function score in the low BMI group (≤24.5 kg/m2 ) (β ± SE: 0.02 ± 0.01, P = 0.013) and negatively associated with cognitive function score in the high BMI group (>24.5 kg/m2 ) (β ± SE: -0.04 ± 0.01, P = 0.009) in multivariable linear regression analysis. In men, higher levels of serum triglycerides and apolipoprotein B were associated with a decreased risk of cognitive impairment. In women, a higher level of high-density lipoprotein cholesterol was associated with a decreased risk of cognitive impairment. CONCLUSION We found inverse U-shaped relationships between BMI and cognitive function and for the gender-specific association of serum lipids with cognitive function. This result indicated that among the elderly population, better nutritional status suggests superior memory status and cognitive function performance.

Abstract
Obesity-related lifestyle factors, such as physical activity behavior and dietary intake, have been shown to be associated with episodic memory function. From animal work, there is considerable biological plausibility linking obesity with worse memory function. There are no published systematic reviews evaluating the effects of obesity on episodic memory function among humans, and examining whether physical activity and diet influences this obesity-memory link. Thus, the purpose of this systematic review was to evaluate the totality of research examining whether obesity is associated with episodic memory function, and whether physical activity and dietary behavior confounds this relationship. A review approach was employed, using PubMed, PsychInfo, and Sports Discus databases. Fourteen studies met our criteria. Among these 14 reviewed studies, eight were cross-sectional, four were prospective, and two employed a randomized controlled experimental design. Twelve of the 14 studies did not take into consideration dietary behavior in their analysis, and similarly, nine of the 14 studies did not take into consideration participant physical activity behavior. Among the 14 studies, ten found an inverse association of weight status on memory function, but for one of these studies, this association was attenuated after controlling for physical activity. Among the 14 evaluated studies, four did not find a direct effect of weight status on memory. Among the four null studies, one, however, found an indirect effect of BMI on episodic memory and another found a moderation effect of BMI and age on memory function. It appears that obesity may be associated with worse memory function, with the underlying mechanisms discussed herein. At this point, it is uncertain whether adiposity, itself, is influencing memory changes, or rather, whether adiposity-related lifestyle behaviors (e.g., physical inactivity and diet) are driving the obesity-memory relationship.

Abstract
OBJECTIVES Overweight/obesity has been implicated to play a role in cognitive deficits in bipolar disorder (BD). This study aims to identify the relationship between body fat distribution and different domains of cognition in BD during euthymia. METHODS A sample of 100 euthymic individuals with BD was measured with a cognitive test battery (i.e., Trail Making Test-A-B/TM-A/B, d2 Test of Attention, Stroop test, California Verbal Learning Test/CVLT) and an anthropometric measures set (body mass index, waist circumference, hip circumference, waist-to-hip-ratio, waist-to-height-ratio, and lipometry). Patient data were compared with a healthy control group (n = 64). RESULTS Results show that overweight patients with BD exhibit lower performance in the TMT-A/B as well as in the free recall performance of the CVLT compared to normal-weight patients with BD and controls. In bipolar individuals, (abdominal) obesity was significantly associated with a poor cognitive performance. In bipolar females, associations with measures of verbal learning and memory were found; in bipolar males, associations with poor performance in the TMT-A/B and in the Stroop interference task were demonstrated. In controls, no associations were found. CONCLUSIONS There are several possible pathways moderating the association between obesity and cognition in BD. Anthropometric and lipometry data underline the substantial mediating impact of body fat distribution on cognition in BD.

The relationship of cognitive performance to concurrent symptoms, cancer- and cancer-treatment-related variables in women with early-stage breast cancer: a 2-year longitudinal study. J Cancer Res Clin Oncol 2016; 142:1461-74.

Abstract
PURPOSE Cognitive dysfunction in women with breast cancer continues to be an area of intense research interest. The prevalence, severity, timing, and cognitive domains that are most affected, as well as the contribution of cancer and its treatments to cognition, remain unresolved. Thus, longitudinal studies are needed that examine cognitive function during different stages of breast cancer treatment and survivorship. This longitudinal trial followed women with early-stage breast cancer, prior to chemotherapy through 2 years survivorship. METHODS In women with early-stage breast cancer (N = -75), performance-based assessment of nine cognitive domains was performed at five time points beginning prior to chemotherapy and finishing 24 months after initial chemotherapy. Linear mixed effects models were used to examine the temporal changes in cognitive performance domains, while adjusting for cofactors, including those related to individuals, tumor attributes, chemotherapy (adjuvant or neoadjuvant), radiation, endocrine therapy, and concurrent symptoms. RESULTS At baseline, scores on reaction time, complex attention, cognitive flexibility, executive function, and visual memory were lower than 90. At 2 years, all domains improved except for the memory domains (verbal, visual, and composite). Scores on six domains (psychomotor speed, reaction time, complex attention, cognitive flexibility, and visual memory) remained lower than 100 at 2 years. Neoadjuvant chemotherapy and fatigue had strong inverse relationship with cognitive functioning at multiple time points. CONCLUSION The low performance-based cognitive scores at baseline and over time warrant further study. Although most scores improved over time, memory did not improve. In all, the level of cognitive function is lower than expected for a majority college-educated sample. Thus, future studies are warranted to replicate these findings and to develop methods for identifying women with cognitive dysfunction pretreatment and into survivorship.

Abstract
The fat mass and obesity associated gene (FTO) has previously been associated with a variety of diseases and conditions, notably obesity, acute coronary syndrome and metabolic syndrome. Reports describing mutations in FTO as well as FTO animal models have further demonstrated a role for FTO in the development of the brain and other organs. Here, we describe a patient born of consanguineous union who presented with microcephaly, developmental delay, behavioral abnormalities, dysmorphic facial features, hypotonia, and other various phenotypic abnormalities. Whole exome sequencing revealed a novel homozygous missense mutation in FTO and a nonsense mutation in the cholesteryl ester transfer protein (CETP). Exome CNV analysis revealed no disease causing large duplications or deletions within coding regions. Patient’s, her parents’ and non-related control’ fibroblasts were analyzed for morphologic defects, abnormal proliferation, apoptosis and transcriptome profile. We have shown that FTO is located in nucleus of cells from each tested samples. Western blot analysis demonstrated no changes in patient FTO. Q-PCR analysis revealed slightly decreased levels of FTO expression in patient cells compared to controls. No morphological or proliferation differences between the patient and control fibroblasts were observed. There is still much to be learned about the molecular mechanisms by which mutations in FTO contribute to such severe phenotypes.

Abstract
Deviations from normal body weight are observed prior to and after the onset of Alzheimer's disease (AD). Midlife obesity confers increased AD risk in later life, whereas late-life obesity is associated with decreased AD risk. The role of underweight and weight loss for AD risk is controversial. Based on the hypothesis of shared genetic variants for both obesity and AD, we analyzed the variants identified for AD or obesity from genome-wide association meta-analyses of the GERAD (AD, cases = 6,688, controls = 13,685) and GIANT (body mass index [BMI] as measure of obesity, n = 123,865) consortia. Our cross-disorder analysis of genome-wide significant 39 obesity SNPs and 23 AD SNPs in these two large data sets revealed that: (1) The AD SNP rs10838725 (pAD = 1.1 × 10(-08)) at the locus CELF1 is also genome-wide significant for obesity (pBMI = 7.35 × 10(-09) ). (2) Four additional AD risk SNPs were nominally associated with obesity (rs17125944 at FERMT2, pBMI = 4.03 × 10(-05), pBMI corr = 2.50 × 10(-03) ; rs3851179 at PICALM; pBMI = 0.002, rs2075650 at TOMM40/APOE, pBMI = 0.024, rs3865444 at CD33, pBMI = 0.024). (3) SNPs at two of the obesity risk loci (rs4836133 downstream of ZNF608; pAD = 0.002 and at rs713586 downstream of RBJ/DNAJC27; pAD = 0.018) were nominally associated with AD risk. Additionally, among the SNPs used for confirmation in both studies the AD risk allele of rs1858973, with an AD association just below genome-wide significance (pAD = 7.20 × 10(-07)), was also associated with obesity (SNP at IQCK/GPRC5B; pBMI = 5.21 × 10(-06) ; pcorr = 3.24 × 10(-04)). Our first GWAS based cross-disorder analysis for AD and obesity suggests that rs10838725 at the locus CELF1 might be relevant for both disorders.

Abstract
Genome wide association studies undoubtedly linked variants of the fat mass and obesity-associated protein (FTO) to obesity. To date, however, knowledge on the mechanisms coupling variants in the intron of the FTO gene to its expression or enzymatic activity to alter metabolism remains scarce. Until recently, the investigation of the molecular function of FTO had not led to conclusive results concerning the 'where', 'when' and 'how' of FTO activity. Finally, since FTO was identified as a RNA modifying enzyme, demethylating N6-methyladenosine on single stranded RNA, novel understanding of the molecular function is gathered. These and other studies suggest the requirement for a further reaching approach to further investigate FTO function, since the phenotype of aberrant FTO function may encompass more than just obesity. Taking these new insights and translating them into appropriate paradigms for functional research in humans may lead to a deeper understanding of the human physiology and disease. This article is part of a Special Issue entitled: From Genome to Function.
