Poor Sleep Quality May Worsen Emotional Burden in T2D
Patients with type 2 diabetes (T2D) who experienced sleep impairments, including short sleep duration, snoring, and insomnia symptoms, were more likely to face an increased risk for diabetes distress. In particular, daytime coping difficulties due to sleep problems showed a notably prominent association with diabetes distress.
METHODOLOGY:
Researchers in Norway conducted a cross-sectional study to explore the association between sleep impairment and diabetes distress in 1954 participants with T2D (mean age, 67.3 years; mean duration of diabetes, 12.1 years) recruited from an ongoing longitudinal population-based study.
Diabetes distress was self-reported using the five-item Problem Areas in Diabetes Questionnaire; a total score of 8 or above denoted high levels of diabetes distress.
Sleep impairments were assessed using the sleeping HUNT (The Trøndelag Health Study) Questionnaire that included questions on snoring, sleep apnoea, insomnia, daytime functioning, and restless legs; the number of hours of sleep at night was assessed using a different question.
TAKEAWAY:
Participants who reported sleep impairments were more often women; had lower socioeconomic status, higher mean BMI, and elevated systolic blood pressure; were current smokers; and exercised less frequently.
Difficulties coping during daytime due to sleep problems showed the strongest association with diabetes distress (regression coefficient [β], 2.6; 95% CI, 1.7-3.6), followed by trouble falling asleep (β, 1.4; 95% CI, 0.8-2.2) and early morning awakening (β, 1.2; 95% CI, 0.7-1.8).
Short sleep duration (≤ 7 hours), snoring, nighttime awakenings, and having restless legs were also associated with higher levels of diabetes distress.
Associations between sleep impairments and diabetes distress were similar between men and women.
IN PRACTICE:
"The assessment of sleep quality should be part of routine diabetes care in people with T2D. Efforts need to be made to raise awareness towards the relationship between sleep impairments and diabetes distress, which further may encourage these individuals to prioritize sleep and seek help when needed," the authors wrote.

What's the Difference Between a Gene and a Chromosome?
Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a single thread of DNA with many different genes. The genes provide instructions for different traits, such as eye or hair color, or male or female sex. Chromosomes come in pairs. Humans have 46 chromosomes, in 23 pairs. People inherit chromosomes from their parents. A child gets one of each pair of chromosomes from their mother and one of each pair of chromosomes from their father. The term ' genetic inheritance ' is the passing down of DNA from parents to children. What is a genetic disorder? Genetic disorders, such as Down syndrome or cystic fibrosis, occur when: there's a change (mutation) in a gene on a chromosome a chromosome is missing a part (called a deletion) when genes move from one chromosome to another (called a translocation) when a cell has extra chromosomes or missing chromosomes A worldwide gene research project, called the Human Genome Project, is creating a map of all human genes and their location on chromosomes. Doctors hope to use this map to find and treat genetic disorders. What do genes and chromosomes have to do with your health? Genes are involved in almost every human trait and disease. They influence how your body responds to: certain health conditions, such as infections medications treatments for health conditions certain behaviors, such as smoking or alcohol use The more we understand how genes affect our health or are linked to disease, the earlier doctors can respond to diseases and provide more effective targeted treatments.

Understanding Non-Mendelian Genetics (Patterns of Inheritance)
In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don't completely follow these principles. Genetics is an expansive field that focuses on the study of genes. Scientists who specialize in genetics are called geneticists. Geneticists study many different topics, including: how genes are inherited from our parents how DNA and genes vary between different people and populations how genes interact with factors both inside and outside of the body If you're looking into more information on genetics topics, you may come across two types of genetics: Mendelian and non-Mendelian genetics. This article reviews both types of genetics, with a focus on non-Mendelian genetics. Continue reading to learn more. What is Mendelian genetics? It's possible that you may remember some concepts of Mendelian genetics from your high school biology class. If you've ever done a Punnett square, you've learned about Mendelian genetics. The principles of Mendelian genetics were established by the Austrian monk Gregor Mendel in the mid-19th century based on his experiments with pea plants. Through his experiments, Mendel pinpointed how certain traits (such as pea color) are passed down across generations. From this information, he developed the following three laws, which are the basis of Mendelian genetics: Dominance. Some variants of a gene, called alleles, are dominant over others. Non-dominant alleles are referred to as recessive. If both a dominant and recessive allele are inherited, the dominant trait will be the one that shows. Segregation. Offspring inherit one allele for a gene from each of their parents. These alleles are passed down randomly. Independent assortment. Genetic traits are inherited independently of each other. Pea color: An example of Mendelian genetics at work To illustrate how Mendelian genetics works, let's use an example with pea plants, in which yellow pea color (Y) is dominant and green pea color (y) is recessive. In this particular example, each parent pea plant is heterozygous, meaning it has a dominant and recessive allele, noted as Yy. When these two plants are bred, noted as Yy x Yy, the following pattern of inheritance will be seen: 25% of offspring will be homozygous dominant (YY) and have yellow peas. 50% of offspring will be heterozygous (Yy) and have yellow peas. 25% of offspring will be homozygous recessive (yy) and have green peas. What are examples of health conditions that follow Mendelian patterns of inheritance? There are several health conditions that follow Mendelian patterns of inheritance. Alleles for sickle cell anemia and cystic fibrosis are recessive. This means that you need two copies of the recessive allele, one from each parent, to have these conditions. In contrast, the allele for Huntington's disease is dominant. That means that you only need a single copy of the allele (from one of your parents) to have it. Sex-linked conditions Some health conditions can be linked to genes in the sex chromosomes (X and Y). For example, hemophilia is X-linked recessive. In those assigned male at birth, who have a single X chromosome, only one copy of the recessive allele is enough to have hemophilia. That's why hemophilia is more common in males. Individuals assigned female at birth have two X chromosomes, meaning they need two copies of the recessive allele to have hemophilia. What are non-Mendelian genetics? Exceptions exist for every rule, and that's also true for genetics. Simply put, non-Mendelian genetics refers to inheritance patterns that don't follow Mendel's laws. Here are some different types of non-Mendelian genetics: Polygenic traits Some traits are determined by two or more genes instead of just one. These are called polygenic traits and don't follow Mendelian inheritance patterns. Examples of polygenic health conditions include: hypertension diabetes certain cancers, such as breast and prostate cancer Mitochondrial inheritance Your mitochondria are the energy factories of your cells and also contain their own DNA, called mtDNA. While there are some exceptions, mtDNA is usually inherited from your mother. You get your mtDNA from your mother because the mitochondria present in sperm typically degrade after fertilization. This leaves behind just the mitochondria in the egg. Examples of Mitochondrial health conditions include Leber hereditary optic neuropathy (LHON) and mitochondrial encephalomyopathy. Epigenetic inheritance Epigenetics refers to how genes are expressed and regulated by factors outside of the DNA sequence. This includes things like DNA methylation, in which a chemical called a methyl group is added to a gene, turning it 'on' or 'off'. Epigenetic factors can change as we get older and are exposed to different things in our environment. Sometimes, these changes can be passed down to the next generation, which is called epigenetic inheritance. Certain cancers (such as breast, colorectal, and esophageal cancer) have been linked to epigenetic changes. Neurological disorders like Alzheimer's and metabolic diseases like Type 2 diabetes have also been associated with epigenetic inheritance. Genetic imprinting While we inherit two copies of a gene, one from each parent, in some cases, only one copy of the gene may be turned 'on' via DNA methylation. This is called imprinting, and it only affects a small percentage of our genes. Which gene is turned 'on' can depend on where the gene came from. For example, some genes are only turned 'on' when they come from the egg, while others are only 'on' when they come from the sperm. Examples of conditions associated with genetic imprinting include Beckwith-Wiedemann syndrome, Silver-Russell syndrome, and Transient Neonatal Diabetes Mellitus. Gene conversion Gene conversion can happen during meiosis, the type of cell division that helps make sperm and eggs. After meiosis, each sperm and egg contains one set of chromosomes and therefore one set of alleles to be passed down to offspring. During meiosis, genetic information from one copy of an allele (the donor) may be transferred to the corresponding allele (the recipient). This results in a genetic change that effectively converts the recipient allele to the donor allele. Genetic conditions influenced by gene conversions include hemophilia A, sickle cell disease, and congenital adrenal hyperplasia. What are examples of health conditions that follow non-Mendelian patterns of inheritance? Most health conditions we're familiar with don't follow Mendelian inheritance patterns. These conditions are often polygenic, meaning the effects of multiple genes contribute to them. For example, cystic fibrosis is caused by inheriting two copies of a recessive allele of a specific gene. However, there's not an isolated 'heart disease' allele that we inherit that causes us to develop heart disease. Mitochondrial disorders, which are caused by changes in mtDNA, are another type of health condition that follows non-Mendelian patterns of inheritance. This is because you typically inherit mtDNA from your mother. Sometimes problems with genetic imprinting can lead to disorders. Prader-Willi syndrome and Beckwith-Wiedemann syndrome are two examples. How do Mendelian and non-Mendelian genetics contribute to our understanding of genetic diseases in humans? Understanding both Mendelian and non-Mendelian inheritance patterns is important in understanding how different genetic diseases may be passed down. For example, if you have a certain genetic disease or you know that one runs in your family, you may have concerns about future children inheriting it. In this situation, working with a medical professional, such as a genetic counselor, who understands a disease's inheritance patterns can help you get an understanding of the risk of future children having the disease. Additionally, understanding genetic changes and inheritance can affect future therapies. This information can be important for developing gene therapies for a variety of genetic diseases. Takeaway Mendelian genetics focuses on the principles that there are dominant and recessive alleles and that we randomly inherit one copy of an allele from each parent. Some health conditions follow basic Mendelian inheritance patterns. Examples include cystic fibrosis and Huntington's disease. Non-Mendelian genetics don't follow the principles outlined by Mendel. Many health conditions we're familiar with don't follow Mendelian inheritance patterns because they're polygenic, affect mtDNA, or are associated with imprinting.

When Medicine Meets Philosophy: A New SEC Series
Medicine and Philosophy, a new roundtable series by the Spanish Society of Cardiology (SEC) in collaboration with Madrid's Círculo de Bellas Artes, aims to facilitate discussions between medical, science, and humanities experts. The series, which took place in May and June, was recorded and can be viewed online at the SEC's channel. Organizers and Topics The Hippocratic Chapter of the SEC, along with organizers from the Círculo de Bella Artes, decided on three healthcare topics to explore in the series. The session titles were "The Doctor-Patient Relationship in the Era of Artificial Intelligence," "Who Wants to Live Forever?", and "Is Boredom a Medical Problem? AI in Medicine: Pros and Cons AI's role in medicine was the first session's focus. Panelists discussed how AI saves time by streamlining data interpretation, allowing more time spent with patients. Ironically, the extra time results in the expectation that patient load should increase. The importance of physician input in AI advancement for medical use, as well as educating future clinicians on AI, were discussed. A Long Life The concept of living a longer life was discussed in the second session. A balanced approach to the topic by medical professionals and philosophers created a crossover of biological facts with existential questions about the meaning of life. Is Boredom Treatable? The last session featured panelists talking about boredom, whether it is a medical issue, and the social and medical repercussions of labeling these normal emotional life experiences as treatable conditions. Were These Roundtables Successful? Yes. All sessions sold out and this success has prompted the organizers to brainstorm future topics for collaboration. Also, expanding this series outside of Madrid is a possibility. Bottom line: Viewing healthcare topics through scientific and philosophical lenses can foster thought-provoking discussions, as shown by the success of the Medicine and Philosophy roundtable series. The full list of panelists can be found on the Círculo de Bellas Artes page for the roundtable series.
