A new paradigm for depression in new mothers: the central role of inflammation and how breastfeeding and anti-inflammatory treatments protect maternal mental health

BACKGROUND: Research in the field of psychoneuroimmunology (PNI) has revealed that depression is associated with inflammation manifested by increased levels of proinflammatory cytokines. DISCUSSION: The old paradigm described inflammation as simply one of many risk factors for depression. The new paradigm is based on more recent research that has indicated that physical and psychological stressors increase inflammation. These recent studies constitute an important shift in the depression paradigm: inflammation is not simply a risk factor; it is the risk factor that underlies all the others. Moreover, inflammation explains why psychosocial, behavioral and physical risk factors increase the risk of depression. This is true for depression in general and for postpartum depression in particular. Puerperal women are especially vulnerable to these effects because their levels of proinflammatory cytokines significantly increase during the last trimester of pregnancy – a time when they are also at high risk for depression. Moreover, common experiences of new motherhood, such as sleep disturbance, postpartum pain, and past or current psychological trauma, act as stressors that cause proinflammatory cytokine levels to rise. Breastfeeding has a protective effect on maternal mental health because it attenuates stress and modulates the inflammatory response. However, breastfeeding difficulties, such as nipple pain, can increase the risk of depression and must be addressed promptly. CONCLUSION: PNI research suggests two goals for the prevention and treatment of postpartum depression: reducing maternal stress and reducing inflammation. Breastfeeding and exercise reduce maternal stress and are protective of maternal mood. In addition, most current treatments for depression are anti-inflammatory. These include long-chain omega-3 fatty acids, cognitive therapy, St. John's wort, and conventional antidepressants

Open-pollinated Corn Variety Trial, 2001

Based on requests from organic producers in Iowa for information on yields and grain quality of open-pollinated corn, a variety trial was developed at the Neely-Kinyon Farm in 2000 and 2001. Open-pollinated (O-P) corn often is preferred by organic farmers, and several O-P corn breeders are operating in Iowa and the Midwest to meet this demand

Impulsive, Disinhibited Behavior—Dining in a Restaurant

Dining in a restaurant with a loved one who has dementia can be an ordeal, especially if the expectations of the caregiver do not match those of the patient and the restaurant environment is not suitable for patients with dementia. The size of the dining area, lighting, background music or noise, décor of the room, number of customers, variety of the items on the menu, number of plates and cutlery on the table, in addition to flowers, candles, and other decorations on the table are all potent distractors. There are so many stimuli; the patient can be overwhelmed with information overload and not able to focus on the main purpose of the event: have dinner and especially enjoy the other person’s company. In this case scenario, we present a 62-year-old man diagnosed with behavioral variant frontotemporal dementia (bvFTD). His daughter “invited” him to have dinner with her at a very fancy restaurant to celebrate her promotion at work. Unfortunately, whereas the evening started very well, it had a catastrophic ending. We discuss what went wrong in the patient/daughter interaction and how the catastrophic ending could have been avoided or averted

Fronto-Temporal Dementia, Diabetes Mellitus and Excessive Eating

Diabetes mellitus is common among older people. Hypoglycemia is a sign of poorly controlled diabetes mellitus and may lead to irritability, agitation, anxiety, hunger, and an excessive food intake, which in turn may make the control of diabetes more difficult. Excessive, inappropriate food intake is also a sign of Fronto-Temporal Dementia (behavioral variant: bvFTD). In this case study, we describe the events leading to an altercation that developed between an older diabetic patient with bvFTD and the staff in an Assisted Living Facility. His first dose of insulin was given early that morning while he was still asleep. He, subsequently, woke up feeling hungry, agitated, and irritable. This, in turn, exacerbated the hyperorality associated with bvFTD. We examine what went wrong in the patient/caregiver interaction and how this potentially catastrophic situation could have been avoided or defused
