Multiple myeloma (MM) is an incurable blood cancer with unclear aetiology. Proteomics is a valuable tool in exploring mechanisms of disease. We investigated the causal relationship between circulating proteins and MM risk, using two of the largest cohorts with proteomics data to-date.

Background: Adiposity is an established risk factor for colorectal cancer (CRC). The pathways underlying this relationship, and specifically the role of circulating proteins, are unclear.

Methods: Utilizing two-sample univariable Mendelian randomization (UVMR), multivariable Mendelian randomization (MVMR), and colocalization, based on summary data from large sex-combined and sex-specific genetic studies, we estimated the univariable associations between: (i) body mass index (BMI) and waist-hip ratio (WHR) and overall and site-specific (colon, proximal colon, distal colon, and rectal) CRC risk, (ii) BMI and WHR and circulating proteins, and (iii) adiposity-associated circulating proteins and CRC risk.

Article Synopsis
  • - The study investigated the potential link between ghrelin, a hormone, and colorectal cancer using a two-sample Mendelian randomization approach, analyzing data from over 54,000 participants.
  • - Results showed no significant association between genetically predicted plasma ghrelin levels and colorectal cancer risk, even when considering factors like sex, cancer subsite, and age at diagnosis.
  • - The findings contribute to the existing evidence suggesting that plasma ghrelin levels do not play a causal role in the development of colorectal cancer.

Colorectal cancer (CRC) is a multi-stage process initiated through the formation of a benign adenoma, progressing to an invasive carcinoma and finally metastatic spread. Tumour cells must adapt their metabolism to support the energetic and biosynthetic demands associated with disease progression. As such, targeting cancer cell metabolism is a promising therapeutic avenue in CRC.

Background: Type 2 diabetes is associated with higher risk of several cancer types. However, the biological intermediates driving this relationship are not fully understood. As novel interventions for treating and managing type 2 diabetes become increasingly available, whether they also disrupt the pathways leading to increased cancer risk is currently unknown.

Background: Recognizing the early signs of cancer risk is vital for informing prevention, early detection, and survival.

Methods: To investigate whether changes in circulating metabolites characterize the early stages of colorectal cancer (CRC) development, we examined the associations between a genetic risk score (GRS) associated with CRC liability (72 single-nucleotide polymorphisms) and 231 circulating metabolites measured by nuclear magnetic resonance spectroscopy in the Avon Longitudinal Study of Parents and Children (N = 6221). Linear regression models were applied to examine the associations between genetic liability to CRC and circulating metabolites measured in the same individuals at age 8 y, 16 y, 18 y, and 25 y.

Article Synopsis
  • The study aimed to understand the link between different types of adiposity (metabolically unfavorable and favorable) and the risk of aggressive prostate cancer using Mendelian randomization.
  • Researchers analyzed data from the PRACTICAL consortium, including over 15,000 aggressive prostate cancer cases, to evaluate the genetic influence of various adiposity traits on cancer risk.
  • The findings indicated no strong associations between either type of adiposity or body mass index (BMI) and aggressive prostate cancer, suggesting metabolic factors aren't the primary influencers of prostate cancer risk, but further research is needed to investigate other potential links.

Restrictive practices (RPs) are a contentious issue in health and social care services. While use may be warranted in some instances, there are risks and concerns around human rights infringements. There are limited data available on the types and incidences of RPs used in health and social care services internationally.

The rising prevalence of childhood obesity has been postulated as an explanation for the increasing rate of individuals diagnosed with type 1 diabetes (T1D). In this study, we use Mendelian randomization (MR) to provide evidence that childhood body size has an effect on T1D risk (OR = 2.05 per change in body size category, 95% CI = 1.

Article Synopsis
  • Endometrial cancer is the most prevalent gynecological cancer in high-income nations and has a significant connection to elevated body mass index (BMI), which is a modifiable risk factor that may influence this cancer more than others.
  • Using Mendelian randomization, researchers examined the causal impact of 14 genetic and molecular risk factors, along with BMI, on the risk of developing endometrial cancer.
  • The analyses revealed a strong link between higher BMI and increased endometrial cancer risk, with additional contributions from hormonal factors like total testosterone, indicating that these molecular traits may mediate the relationship between BMI and the disease.

Background: Attention-Deficit/Hyperactivity Disorder (ADHD) is a childhood mental disorder characterized by inattention, impulsiveness and overactivity. It is also characterized by heterogeneity and ambiguity. Effective intervention is influenced by these two factors.

Background: A specialist patch test clinic was set up in April 1997 at the Department of Dermatology, South Infirmary-Victoria Hospital, Cork, Ireland. The number of batteries available was expanded from six to 21 and the routine testing of patients to their own products was introduced, as was prick testing for latex hypersensitivity.

Objectives: To assess the impact of introducing this clinic on the detection of allergic contact dermatitis.

A new test of posture and mobility has been applied to a small group of spina bifida children with different lower limb motor levels, and to a further group of children with both spina bifida and associated cerebral palsy of the hemiplegic type. It is demonstrated that this test of posture and mobility is applicable to spina bifida children and that gross motor handicap is therefore quantifiable. The posture and mobility scores of children with spina bifida or cerebral palsy is significantly less than those of normal children and the scores for children with both spina bifida as well as cerebral palsy is significantly lower than having either alone.
