Diabetes and dyslipidemia are common in patients with psychosis and may be related to adverse effects of antipsychotic medications. Metabolic disturbances in first-episode patients with psychosis are common, even prior to any antipsychotic treatment, and antipsychotic medications are implicated in the development of metabolic syndrome, at least in the long run. We therefore aimed to follow a group of drug-naïve, first-episode patients with psychosis at different time points (baseline, six months, and 36 months after the initiation of antipsychotic treatment) in order to evaluate the progression of metabolic abnormalities after antipsychotic therapy and the time-course of their onset.

Prospective associations of leucocyte subtypes and obesity with the risk of developing cutaneous malignant melanoma in the UK Biobank cohort.

BMC Cancer

May 2024

Department of Epidemiology and Biostatistics, School of Public Health, Imperial College London, White City Campus, 90 Wood Lane, London, W12 0BZ, UK.

Background: Obesity is associated with chronic low-grade inflammation, which is linked to cancer development. Abdominal obesity (a body mass index, ABSI), however, has unusually been associated inversely with cutaneous malignant melanoma (CMM), while general obesity (body mass index, BMI) is associated positively. Leucocytes participate in inflammation and are higher in obesity, but prospective associations of leucocytes with cutaneous malignant melanoma are unclear.

Article Synopsis
  • Colorectal cancer (CRC) is a widely increasing disease linked to high body mass index (BMI), but the exact biological processes connecting these two factors are not well understood.
  • The study employed Mendelian randomization to explore various biomarkers and lifestyle factors potentially mediating the impact of BMI on CRC risk, focusing on elements like inflammation, insulin levels, and physical activity.
  • The findings indicated that higher genetically predicted BMI correlates with increased CRC risk, with evidence suggesting that the relationship might be partly mediated by plasma IGF1, while smoking and physical activity appear to complicate the association rather than mediate it.

Fine-mapping analysis including over 254,000 East Asian and European descendants identifies 136 putative colorectal cancer susceptibility genes.

Nat Commun

April 2024

Division of Epidemiology, Department of Medicine, Vanderbilt-Ingram Cancer Center, Vanderbilt Epidemiology Center, Vanderbilt University Medical Center, Nashville, TN, USA.

Genome-wide association studies (GWAS) have identified more than 200 common genetic variants independently associated with colorectal cancer (CRC) risk, but the causal variants and target genes are mostly unknown. We sought to fine-map all known CRC risk loci using GWAS data from 100,204 cases and 154,587 controls of East Asian and European ancestry. Our stepwise conditional analyses revealed 238 independent association signals of CRC risk, each with a set of credible causal variants (CCVs), of which 28 signals had a single CCV.

Tissue-specific genetic variation suggests distinct molecular pathways between body shape phenotypes and colorectal cancer.

Sci Adv

April 2024

International Agency for Research on Cancer (IARC/WHO), Nutrition and Metabolism Branch, 69366 Lyon CEDEX 07, France.

It remains unknown whether adiposity subtypes are differentially associated with colorectal cancer (CRC). To move beyond single-trait anthropometric indicators, we derived four multi-trait body shape phenotypes reflecting adiposity subtypes from principal components analysis on body mass index, height, weight, waist-to-hip ratio, and waist and hip circumference. A generally obese (PC1) and a tall, centrally obese (PC3) body shape were both positively associated with CRC risk in observational analyses in 329,828 UK Biobank participants (3728 cases).

Article Synopsis
  • Menopausal hormone therapy (MHT) may lower the risk of colorectal cancer (CRC), especially in women with a higher genetic predisposition to the disease.
  • In a study of nearly 30,000 postmenopausal women, those in the highest genetic risk quartile saw a significantly greater reduction in CRC risk when using MHT compared to those in the lowest quartile.
  • The findings suggest that integrating genetic risk information could improve CRC risk predictions and inform the assessment of MHT benefits in postmenopausal women.

Genome-wide association studies and Mendelian randomization analyses provide insights into the causes of early-onset colorectal cancer.

Ann Oncol

June 2024

Nutrition and Metabolism Branch, International Agency for Research on Cancer, World Health Organization, Lyon, France. Electronic address:

Background: The incidence of early-onset colorectal cancer (EOCRC; diagnosed <50 years of age) is rising globally; however, the causes underlying this trend are largely unknown. CRC has strong genetic and environmental determinants, yet common genetic variants and causal modifiable risk factors underlying EOCRC are unknown. We conducted the first EOCRC-specific genome-wide association study (GWAS) and Mendelian randomization (MR) analyses to explore germline genetic and causal modifiable risk factors associated with EOCRC.

Article Synopsis
  • Obesity is linked to various types of colorectal cancer (CRC), but the strength and cause of these links are not fully understood.
  • By using Mendelian randomization, researchers studied how body size traits like BMI, waist circumference, and body fat percentage affect risks for different CRC subtypes.
  • Results showed that higher BMI and body fat significantly increased the risks for serrated and alternate CRC pathways (Jass types 1, 2, and 3), while associations with the traditional pathway (Jass type 4) were weaker.

Background: Traditional body-shape indices such as Waist Circumference (WC), Hip Circumference (HC), and Waist-to-Hip Ratio (WHR) are associated with colorectal cancer (CRC) risk, but are correlated with Body Mass Index (BMI), and adjustment for BMI introduces a strong correlation with height. Thus, new allometric indices have been developed, namely A Body Shape Index (ABSI), Hip Index (HI), and Waist-to-Hip Index (WHI), which are uncorrelated with weight and height; these have also been associated with CRC risk in observational studies, but information from Mendelian randomization (MR) studies is missing.

Methods: We used two-sample MR to examine potential causal cancer site- and sex-specific associations of the genetically-predicted allometric body-shape indices with CRC risk, and compared them with BMI-adjusted traditional body-shape indices, and BMI.
