Thiamin is a water-soluble vitamin also known as vitamin B1. Its biologically active form, thiamin pyrophosphate (TPP), is a cofactor in macronutrient metabolism. In addition to its coenzyme roles, TPP plays a role in nerve structure and function as well as brain metabolism. Signs and symptoms of thiamin deficiency (TD) include lactic acidosis, peripheral neuropathy, ataxia, and ocular changes (eg, nystagmus). More advanced symptoms include confabulation and memory loss and/or psychosis, resulting in Wernicke's encephalopathy and/or Wernicke's Korsakoff syndrome, respectively. The nutrition support clinician should be aware of patients who may be at risk for TD. Risk factors include those patients with malnutrition due to 1 or more nutrition-related etiologies: decreased nutrient intake, increased nutrient losses, or impaired nutrient absorption. Clinical scenarios such as unexplained heart failure or lactic acidosis, renal failure with dialysis, alcoholism, starvation, hyperemesis gravidarum, or bariatric surgery may increase the risk for TD. Patients who are critically ill and require nutrition support may also be at risk for TD, especially those who are given intravenous dextrose void of thiamin repletion. Furthermore, understanding thiamin's role as a potential therapeutic agent for diabetes, some inborn errors of metabolism, and neurodegenerative diseases warrants further research. This tutorial describes the absorption, digestion, and metabolism of thiamin. Issues pertaining to thiamin in clinical practice will be described, and evidence-based practice suggestions for the prevention and treatment of TD will be discussed.

Pregnancy is an insulin resistant state. Hyperglycaemia and gestational diabetes mellitus are well-recognised complications even in women without existing metabolic syndrome or obesity. Pregnant women also appear to be more vulnerable to ketoacidosis, particularly after short periods of reduced oral intake in the third trimester, and may present with very severe starvation ketoacidosis, prompting emergent delivery. We present a case of a woman with a background of depression and psychotic episodes. Olanzapine had been commenced after a psychotic episode at 20 weeks' gestation. Gestational diabetes mellitus was diagnosed at 28 weeks, and she was then admitted at 31 weeks with severe euglycaemic ketoacidosis following a short period of vomiting. She underwent caesarean section when the metabolic disturbances did not resolve with medical treatment. We believe atypical antipsychotic therapy contributed to the profound insulin resistance seen here, and that obstetricians, physicians and psychiatrists must be aware of the risks conferred by these agents in pregnancy.

Multiple sclerosis, currently incurable and potentially profoundly disabling demyelinating central nervous system disease, is associated with higher occurrence of suicide as affected individuals are prone to major depression and psychosis. Despite progressively incapacitating neurologic impairment, well-staffed institutions, and limited repertoire of methods of suicide, which prevents patients from purposefully ending their lives, suicide-determined patients typically commit suicide resulting from a medication overdose, sharp force traumata, self-neglect, or deliberate starvation. Here we describe a successful suicide committed by a 39-year-old wheelchair-bound, institutionalized, quadriparetic male patient with a diagnosis of multiple sclerosis with secondary progressive clinical course who utilized his motorized wheelchair to terminate his life. He tied a rope between his neck and wall bars and then propelled the wheelchair forwardly. The acceleration of the wheelchair resulted in ligature self-strangulation. This case report, with a review of the literature, is noteworthy for the rareness of the wheelchair-related fatality combined with an unusual, if not entirely unseen, suicidal mechanism in severely disabled adult.

The aim of this article is to emphasize that starvation is an important potential consequence of psychosis and to provide recommendations for management of this condition. A review of the literature on food refusal and starvation in patients with psychotic illnesses was performed. Our search strategy returned 54 articles with one article meeting inclusion criteria. Additional independent research returned an additional four cases of patients with psychosis engaging in self-starvation. The cases of several patients from our institution who engaged in self-starvation behaviors as a result of psychosis are also presented. The management and outcomes of each of these 10 patients are discussed. Starvation secondary to psychosis is an important but underappreciated consequence of psychosis that can lead to serious adverse outcomes in these patients. Few cases have been reported in the literature. More study is warranted to develop evidence-based management guidelines.
