Feeding behaviors among incident cases of schizophrenia in a psychiatric hospital: Association with dimensions of psychopathology and social support

Psychiatric Explanations of Poor Oral Intake: A Clinically Focused Review

BACKGROUND

Poor oral intake (POI) among medical-surgical inpatients can cause malnutrition and delay recovery due to medical consequences and the need for more invasive nutritional support. Many psychiatric conditions can cause POI; however, the role that psychiatric conditions play in POI has received limited attention to date.

OBJECTIVE

This review aggregates available information on POI due to psychiatric conditions and provides a framework for the clinical approach to these conditions in hospitalized adult patients.

METHODS

We searched PubMed and EMBASE for reviews of POI due to psychiatric causes, but no relevant publications were identified. Diagnostic criteria for relevant conditions in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision and Rome IV were reviewed, as were C-L psychiatry textbooks and relevant society websites. This review was further supplemented by a case conference at the authors' institution.

RESULTS

We have divided results into five sections for clinical utility: (1) the need to rule out medical causes of POI; (2) unpleasant somatic experiences, including psychotropic causes; (3) mood, psychotic, catatonic, and neurocognitive disorders that can present with POI; (4) eating and feeding disorders; and (5) personal and interpersonal explanations of POI. Within each section, we review how to identify and manage each condition, specifically considering the effects of treatment on oral intake.

CONCLUSIONS

The clinical management of POI varies based on cause. For instance, psychostimulants can cause POI due to inappetence; however, they can treat POI due to abulia by improving motivation. The fact that such a broad range of psychiatric conditions can cause POI calls for a systematic clinical approach that considers the categories of potential causes. We also identified a need for prospective studies focused on the management of POI due to psychiatric conditions, as the literature on this topic is limited to case reports, case series, and retrospective cohort studies.

Hypothalamic Subunit Volumes in Schizophrenia and Bipolar Spectrum Disorders

BACKGROUND

The hypothalamus is central to many hormonal and autonomous nervous system pathways. Emerging evidence indicates that these pathways may be disrupted in schizophrenia and bipolar disorder. Yet, few studies have examined the volumes of hypothalamic subunits in these patient groups. We compared hypothalamic subunit volumes in individuals with psychotic disorders to healthy controls.

STUDY DESIGN

We included 344 patients with schizophrenia spectrum disorders (SCZ), 340 patients with bipolar disorders (BPD), and 684 age- and-sex-matched healthy controls (CTR). Total hypothalamus and five hypothalamic subunit volumes were extracted from T1-weighted magnetic resonance imaging (MRI) using an automated Bayesian segmentation method. Regression models, corrected for age, age2, sex, and segmentation-based intracranial volume (sbTIV), were used to examine diagnostic group differences, interactions with sex, and associations with clinical symptoms, antipsychotic medication, antidepressants and mood stabilizers.

STUDY RESULTS

SCZ had larger volumes in the left inferior tubular subunit and smaller right anterior-inferior, right anterior-superior, and right posterior hypothalamic subunits compared to CTR. BPD did not differ significantly from CTR for any hypothalamic subunit volume, however, there was a significant sex-by-diagnosis interaction. Analyses stratified by sex showed smaller right hypothalamus and right posterior subunit volumes in male patients, but not female patients, relative to same-sex controls. There was a significant association between BPD currently taking antipsychotic medication and the left inferior tubular subunits volumes.

CONCLUSIONS

Our results show regional-specific alterations in hypothalamus subunit volumes in individuals with SCZ, with relevance to HPA-axis dysregulation, circadian rhythm disruption, and cognition impairment.

A rare case report of teen-onset pica in a female patient with a clinical high risk for psychosis

AIM

We aimed to further elucidate the under-researched, underdiagnosed and misunderstood comorbid pica in the context of psychosis.

METHOD

We report a case of teen-onset plastophagia in an antipsychotic-naïve girl at ultra-high risk (UHR) for psychosis.

RESULTS

HA is a 17-year-old unmarried girl who had a history of good premorbid functioning, no personal psychiatric history and an uncle with schizophrenia. She was referred to our psychiatry department with the complaint of having the habit of eating plastic for about 2 years. A thorough clinical history revealed that she developed, since more than a year, difficulty in school and interpersonal functioning. After clinical evaluation, a diagnosis of UHR with major depressive disorder, iron deficiency anaemia and pica was made.

CONCLUSION

We draw attention to the possibility of an overlap between the pathogenesis of pica and psychosis, and we highlight the importance of early diagnosis and management of both pica and UHR since they can lead to serious medical and mental consequences.

Pica in a Patient With Decompensated Schizophrenia

Although pica is commonly associated with nutritional deficiencies, it is also observed in psychiatric disorders such as obsessive-compulsive disorder and less commonly in schizophrenia. We describe a case of pica in a 34-year-old male with decompensated schizophrenia. Emergency medical services brought the patient from a state facility as he was scavenging and eating foreign objects. Upon initial evaluation, no notable nutritional deficiencies were noted. After surgical removal of foreign objects, he was started on antipsychotics. His pica was determined to be due to his active psychosis involving delusions, disorganized thought processes, and loosening of associations. His psychosis improved on paliperidone intramuscular injection and oral olanzapine, which coincided with reduction and resolution of pica. Our case highlights the need to understand further the exact psychopathology of pica that may not be limited to nutritional deficiencies.

Pica behaviors in schizophrenia: a call for further research

Pica as a scavenging behavior represents a serious health hazard to the care of patients with schizophrenia. Despite the rare comorbidity of pica eating disorder and schizophrenia, pica behaviors are relatively common in this group of patients (1.5% vs. 14.3%). The risk of multiple clinical problems such as electrolyte disturbances, intestinal obstruction, and heavy metal poisoning has made pica behaviors an important research topic in patients with schizophrenia. However, few studies have examined the etiology, mechanisms, and treatment of pica behaviors in schizophrenia. This letter is a call for further research into discovering the biopsychopathology of these major clinical manifestations among patients with schizophrenia.

Assessing psychological needs in female cancer patients: a tailored model

BACKGROUND AND AIM OF THE WORK

Psychosocial needs in cancer patients seem to be underestimated and undertreated. The present research was designed to explore under-considered psychosocial needs (e.g., stressful life events, perceived social support, sense of mastery and depressive/anxious symptoms) of a female cancer group. The aim of the study was to test an assessment psycho-oncological model for female cancer patients. An assessment model of psychosocial needs and Stressful Life Events was operationalized and tests its predictive power.

METHODS

We used Discriminant Analysis to test predictive power of the model and of the single variables included in it. 236 oncological patients (mean age 55.50 ± 13.09) were matched with 232 healthy control groups in the study. The following instruments were chosen: the Florence Psychiatric Interview, Hospital Anxiety Depression Scale, Multidimensional Scale of Perceived Social Support, Beck Depression Inventory I, and Sense of Mastery.

RESULTS

The model satisfied the assumption criteria and was significant (Ʌ= .680, X2 = 109.73, p< .001).

CONCLUSIONS

Stressful events, depression and anxiety were adequate markers of the assessment psycho-oncological model proposed for female cancer patients. The present study provides contributions in a clinical perspective: the results support the relevance of considering an assessment psychosocial model to use in female oncology for an accurate estimation of the women's needs. Women affected by female cancer with an history of Stressful Early and Recent life events and high level of anxiety and depression could positively benefit from a psychotherapy treatment.

The Association between Lifestyle Choices and Schizophrenia Symptoms

Due to poor eating habits, insufficient physical activity, and nicotine use, schizophrenia patients are at increased risk of lifestyle diseases. Factors contributing to unhealthy behaviors include lower socioeconomic status and level of education as well as social isolation. Schizophrenia manifestations such as amotivation, apathy, and cognitive deficits can further hinder development of proper health habits. The aim of this study was to assess the possible association between lifestyle-related choices and schizophrenia symptoms severity. This observational study enrolled 106 patients with schizophrenia (42 Males/64 Females), 18–69 years (mean: 41.89 ± 9.7 years). Mean duration of schizophrenia was 14.61 ± 9.7 years. Multiple significant correlations were found between patients’ lifestyle and their biochemical laboratory parameters (lipid profile and fasting glucose). Most importantly, a significant link emerged between presented habits and schizophrenia symptom severity. There were also significant gender differences in the intake of sweets and sweet beverages. Quite unexpectedly, a behavioral shift towards more healthy lifestyle choices was observed after completion of questionnaires on lifestyle and health habits. There are clear benefits to systematic provision of educational interventions concerning physical activity and proper eating habits to schizophrenia patients. These simple preventive measures could significantly improve both mental and physical health outcomes in schizophrenia patient populations.

Double burden of malnutrition amongst patients with first-episode schizophrenia in a psychiatric hospital: A 1-year follow-up study

BACKGROUND

Despite the burgeoning data on the double burden of malnutrition (DBM) in sub-Saharan Africa, longitudinal studies to examine malnutrition amongst first-episode schizophrenia are uncommon in the modern literature.

AIM

To determine the extent of nutritional variations amongst persons with schizophrenia at intervals of 1-year treatment follow-up.

SETTING

This study was conducted at the Federal Neuropsychiatric Hospital, Enugu, Nigeria.

METHODS

Consecutive incident cases that fulfilled the criteria for schizophrenia were recruited into the study. After a baseline assessment, 206 incident cases of schizophrenia were followed up at 4th, 8th, 12th weeks, 6 months and 1 year for indicators of nutritional outcome. The body mass index (BMI) was used to measure the nutritional status amongst the study participants. Changes in the BMI across intervals of follow-up were examined using repeated measures analysis of variance, whereas the socio-demographic and clinical variables were evaluated as predictors of outcome using multiple regression analysis.

RESULTS

After 1 year of treatment with antipsychotics, the prevalence of underweight decreased from 19.9% (95% CI, 19.8% - 20.0%) at baseline to 16.0% (95% CI, 15.9% - 16.1%) at 1 year, but the prevalence of overweight/obesity increased from 29.1% (95% CI, 29.0% - 29.2%) at baseline to 43.2% (95% CI, 43.0% - 43.3%) at 1 year of follow-up. The predictors of BMI at 1 year were antipsychotic medication (32.7% variance), duration of vagrancy (24.0%) and age at onset (20.0%).

CONCLUSION

The finding of coexistence of undernutrition and overnutrition across the intervals of treatment follow-up underscores the need for comprehensive interventions to address both extremes of malnutrition amongst patients with schizophrenia.
