OBJECTIVES: To investigate the nutritional status and its influencing factors in children with newly diagnosed inflammatory bowel disease (IBD). METHODS: A retrospective analysis was conducted on the clinical data of children who were diagnosed with IBD for the first time in Hunan Children's Hospital from January 2015 to December 2021. Diagnostic delay was defined as the time from the symptom onset to IBD diagnosis being in the upper quartile (P76-P100) of all IBD children in the study. Multivariate logistic regression analysis was used to explore the risk factors for emaciation and growth retardation. RESULTS: A total of 125 children with newly diagnosed IBD were included, with Crohn's disease being the main type (91.2%). The rates of emaciation and growth retardation were 42.4% (53 cases) and 7.2% (9 cases), respectively, and the rate of anemia was 77.6% (97 cases). Diagnostic delay was noted in 31 children (24.8%), with the time from the symptom onset to IBD diagnosis of 366 to 7 211 days. Multivariate logistic regression analysis showed that diagnostic delay was a risk factor for emaciation and growth retardation (OR=2.73 and OR=4.42, respectively; P<0.05) and that age was positively associated with emaciation (OR=1.30, P<0.05). CONCLUSIONS: Children with newly diagnosed IBD have poor nutritional status, and the rates of anemia, emaciation, and growth retardation are high. Diagnostic delay is associated with malnutrition in children with IBD.

Diencephalic syndrome-like presentation of brainstem tumor: a series case-based review.

PURPOSE: Russel described a rare clinical entity known as diencephalic syndrome (DS) in 1951, which was traditionally caused by a neoplasm in the hypothalamic-optic chiasmatic region. DS is characterized by severe emaciation despite adequate or slightly reduced caloric intake, locomotor hyperactivity, euphoria and other minor features. Current evidence suggests that a rare population of children with a similar phenotype may have their tumor located in the posterior fossa instead, defining the DS-like presentation, a rare entity with few cases reported in the literature. METHODS: A thorough search of three databases (PubMed, Ovid Medline, and Ovid Embase) was conducted to identify relevant papers reporting children with DS associated with brainstem tumors. To our knowledge, only seven cases have been documented in the literature. Moreover, we present four of our own cases, focusing on the unusual clinical presentation, the diagnosis process, and the lag time between the initial symptoms and the definitive diagnosis. RESULTS: In this review, the mean lag time between the onset of symptoms and diagnosis was 20.9 months (median: 16 months; range: 1.5-72 months), whereas in our series of cases, the time was 32.5 months (median: 33 months; range: 7-57 months). CONCLUSION: Despite recent significant advances in neuro-oncology diagnostic tools, this mean lag time did not improve when compared with the previous literature review from 1976. Throughout these data, we aim to raise awareness in the hopes of detecting intracranial neoplasms earlier in cases of children with profound emaciation of unknown cause.

Prevalence and predictors associated with severe pulmonary hypertension in COPD.

BACKGROUND: Pulmonary hypertension (PH) is one of the most common complications of COPD (chronic obstructive pulmonary disease), but its severe form is uncommon. Various factors play an important role in the occurrence and severity of pulmonary hypertension in patients. METHODS: This cross-sectional study was performed on patients with COPD referred to an emergency department over a one-year period. The tests-including complete blood count (CBC) and arterial blood gas (ABG), pulmonary functional test (PFT) and echocardiography-were performed for all patients to measure mPAP (mean pulmonary artery pressure), ejection fraction (EF) and body mass index (BMI). The prevalence of severe pulmonary hypertension and its associated factors were investigated in these patients. RESULTS: A total of 1078 patients was included in the study, of whom 628 (58.3%) were male and 450 (41.7%) were female. The mean age of the patients undergoing the study was 70.1±12.2. A total of 136 (13.7%) of them had mPAP (mm Hg)≥40mm Hg as severe pulmonary hypertension. Following multivariable analysis by using the backward conditional method, it was shown that seven variables had a significant correlation with severe PH. CONCLUSIONS: The results showed that there is an independent correlation between hypoxia, hypopnea and compensatory metabolic alkalosis, polycythemia, left ventricular dysfunction, emaciation, and cachectic with severe pulmonary hypertension. The prevalence of severe PH in these patients was 13.7%.

Laparoscopic repair for a previously unreported form of ventral hernia on the right iliac fossa in an elderly emaciated woman.

An 81-year-old emaciated woman was admitted to our hospital with a one-year history of recurrent bilateral inguinal swellings. Palpable lumps were observed not only in bilateral groin areas, but also on the right iliac fossa (RIF) of her abdomen. During a planned transabdominal preperitoneal laparoscopic herniorrhaphy, a previously unreported form of ventral hernia was observed at a position lateral and cranial to the right internal inguinal ring, which probably corresponded to the palpable lump on the RIF. The hernia orifice was 2 cm in diameter, and a vascular structure ran through the orifice. The contents of the hernia consisted of fatty tissue arising from the retroperitoneal tissue. Routine exploration revealed orifices of the following hernias: left indirect, right direct, bilateral femoral, bilateral obturator, and right Spigelian hernia. Her postoperative course was uneventful and a mass on the right lower quadrant disappeared after operation.

Management and treatment of eating disorders with severe medical complications on a psychiatric ward: a study of 9 inpatients in Japan.

OBJECTIVE: To describe eating disorders inpatients with severe medical complications and elucidate the problems in managing them on a psychiatric ward. METHOD: Of the 111 eating disorders patients hospitalized on our psychiatric ward from January 2005 to December 2012, 9 had eating disorders with severe medical complications. Through chart review and computerized data collection, we retrospectively evaluated patient clinical data. RESULT: All 9 patients were women, with a mean age of 22.4±5.7 years, mean body weight of 26.2±3.0 kg, and mean body mass index of 10.5±1.5 on admission. Severe medical complications commonly seen were severe hypoglycemia, refeeding syndrome, coagulation abnormality, and severe liver dysfunction. Three patients died during hospitalization. All patients were managed mainly on the psychiatric ward despite their abnormally low body weight and severe medical complications. CONCLUSIONS: Patients with eating disorders, although physically serious, often need to be managed on a psychiatric ward, even at the risk of providing less than ideal care for their physical complications. It is important to assess patient status both physically and psychologically and to select an appropriate therapeutic environment for safe and effective treatment.

Causes of death in forensic autopsy cases of malnourished persons.

PURPOSE: Medical examiners and forensic pathologists often encounter emaciated bodies in postmortem examinations. However, the main disease that caused death is often not clear and measures to prevent the unexpected death of malnourished persons have not been established. In this study, we examined the underlying causes of death among a large number of forensic autopsy cases that showed emaciation to clarify the features of sudden, unexpected death in malnourished persons. METHODS: Documents of autopsy cases without putrefaction handled during 2007-2010 by the Tokyo Medical Examiner's Office were reviewed (n=7227). The body mass index (BMI) was calculated for each case. The causes of death for cases with severe malnutrition (BMI<16; n=885) were closely examined. RESULTS: About 70% of all deaths in malnourished cases (BMI<16) was due to disease, and the causative diseases are more varied than in those with less severe malnutrition and those without malnutrition (BMI⩾16). A higher proportion of malnutrition as the cause of death was observed in younger persons for both sexes, and a higher proportion of having a history of psychiatric diseases was observed in younger deceased women. In addition, a higher proportion of alcohol-related digestive diseases was observed especially in younger men, some of whom had a history of alcohol dependence. On the other hand, the proportion of organic diseases, such as neoplasms and gastroduodenal ulcer, was higher in older deceased persons, especially among men. Around 70% of all respiratory diseases comprised pneumonia in both sexes. Among non-disease-related causes of death, poisoning was the most frequent cause in women under 55years old (35.3%), with the majority having had a history of psychiatric disease. CONCLUSIONS: Because autopsy cases of malnourished persons show various causes of death, physicians have to pay more attention in making death diagnosis in such cases. From a preventative point of view, early detection of organic diseases, a better approach toward managing psychiatric diseases, and implementation of vaccination for pneumonia will contribute to reduction of future unexpected deaths among malnourished persons.

Mineral density and biomechanical properties of bone tissue from male Arctic foxes (Vulpes lagopus) exposed to organochlorine contaminants and emaciation.

We investigated the impact from dietary OC (organochlorine) exposure and restricted feeding (emaciation) on bone mineral density (BMD; g hydroxy-apatite cm(-2)) in femoral, vertebrate, skull and baculum osteoid tissue from farmed Arctic blue foxes (Vulpes lagopus). For femur, also biomechanical properties during bending (displacement [mm], load [N], energy absorption [J] and stiffness [N/mm]) were measured. Sixteen foxes (EXP) were fed a wet food containing 7.7% OC-polluted minke whale (Balaenoptera acutorostrata) blubber in two periods of body fat deposition (Aug-Dec) and two periods of body fat mobilisation (Jan-July) in which the food contained less energy and only 2% blubber. SigmaOC food concentration in the food containing 7.7% whale blubber was 309 ng/g wet mass. This corresponded to a SigmaOC exposure of ca. 17 microg/kg body mass/d and a responding SigmaOC residue in subcutaneous adipose tissue of ca. 1700 ng/g live mass in the 8 EXP fat foxes euthanized after 16 months. A control group (CON) composed of 15 foxes were fed equal daily caloric amounts of clean pork (Sus scrofa) fat. After 16 months, 8 EXP and 7 CON foxes were euthanized (mean body mass=9.25 kg) while the remaining 8 EXP and 8 CON foxes were given restricted food rations for 6 months resulting in a body weight reduction (mean body mass=5.46 kg). The results showed that only BMD(skull) vs. BMD(vertebrae) were significantly correlated (R=0.68; p=0.03; n=10) probably due to a similar composition of trabecular and cortical osteoid tissue. No difference in any of the BMD measurements or femoral biomechanical properties was found between EXP and CON foxes although BMD baculum was 1.6-folds lower in the EXP group. However, lean summer foxes had significantly lower femoral biomechanical properties measured as displacement (mm), energy absorption (J) and time (s) biomechanical properties than fat winter foxes (all p<0.004). This indicates lower stiffness and softer bones from fasting which is in agreement with previous studies. Further, it should be kept in mind when studying bone tissues in Arctic mammals also in order to avoid confounding effects from body condition.

The Shetland Islands scrapie monitoring and control programme: analysis of the clinical data collected from 772 scrapie suspects 1985-1997.

There were 574 scrapie positive suspects (histopathological scrapie lesions present) and 198 scrapie negative suspects (histopathological scrapie lesions absent). The greatest number of scrapie cases were recorded in sheep of 2, 3 and 4 years of age which represented 17%, 36% and 23% of the scrapie positive suspects, respectively. The sign sensitivities and specificities for the ten recorded signs were, respectively: pruritus (62%, 42%), ataxia (23%, 74%), hyperaesthesia (32%, 74%), wool loss (25%, 73%), fleece discolouration (29%, 85%), bruxism (23%, 69%), nibbling reflex (17%, 58%), head rubbing (47%, 78%), poll rubbing (25%, 83%). These single signs had poor discriminatory values with likelihood ratios close to one (range 0.89-1.21); combinations of the four signs, pruritus, wool loss, ataxia, hyperaesthesia and emaciation were more discriminatory (range 0.30-4.3). This study covered a time period when bovine spongiform encephalopathy (BSE) might have been introduced into the sheep population on the Shetland Islands via contaminated feed. No temporal changes could be detected in the age structure of the affected animals.

Incidence and prognostic value of malnutrition and wasting in human immunodeficiency virus-infected outpatients.

Although malnutrition and wasting are known features of human immunodeficiency virus (HIV) infection, their incidence and possible association with immunologic impairment are largely unknown, as is the prognostic value of the nutritional state. Nutritional, clinical, and immunologic parameters were measured in 100 outpatients in different stages of HIV infection. In addition, 39 patients with AIDS were prospectively followed for a mean period of 343 (range, 53-650) days. Sixty-three percent of the patients showed evidence of malnutrition, 21% suffered from wasting. A reduced body cell mass and decreased serum albumin levels were observed in 32 and 14%, respectively, predominantly in more advanced disease stages. Fourteen of 39 AIDS patients died after a mean survival of 212 days. Survivors showed significantly larger initial body cell mass values and higher initial serum albumin levels compared with nonsurvivors, whereas CD4+ lymphocyte counts, disease complications, and medication were all similar in both groups. Kaplan-Meier analyses revealed a significantly prolonged survival in patients with a body cell mass > 30% of body weight or serum albumin levels exceeding 30 g/L. Factor analyses indicated that the parameters of nutritional state were independent from each other and from CD4+ lymphocyte counts. Malnutrition occurs frequently during HIV infection and increases with disease progress. It strongly predicts patient survival independent of CD4+ lymphocyte counts.

Improved body weight status as a result of nutrition intervention in adult, HIV-positive outpatients.

OBJECTIVE: Malnutrition is an important consequence of infection with the human immunodeficiency virus (HIV); involuntary weight loss greater than 10% is one criterion that the Centers for Disease Control and Prevention uses for the diagnosis of acquired immunodeficiency syndrome (AIDS). This study was designed to determine whether nutrition intervention in a group of adult, HIV-positive outpatients affected weight maintenance. METHODS: We undertook a retrospective review of 175 patient charts from the AIDS Reproductive Health Clinic and the Center for Special Studies at The New York Hospital. Forty-nine charts were excluded because the patient expressed a desire to reduce weight, discontinued medical care, or died. Seven charts were eliminated because of missing data. In the remaining patients (n = 119), weights were recorded for the initial clinic contact and for a follow-up visit at least 6 months later. Nutrition intervention completed by a registered dietitian was indicated on 42 patient charts (intervention group); intervention included dietary assessment, intake analysis, appropriate counselling, follow-up, and provision of supplements as needed. The remaining 77 charts did not indicate nutrition intervention; this group was called the nonintervention group. Differences between the intervention and nonintervention groups were analyzed using the two-tailed Fisher exact test and the Mann-Whitney nonparametric test. RESULTS: Forty-two subjects (35% of the total) recieved nutrition intervention, including all of those with gastrointestinal problems (n = 10) and wasting (n = 11). Individuals in the intervention group gained a significant (P < .02) 1.2 +/- 11.4 lb (mean +/- standard deviation; median = +3 lb) compared with those in the nonintervention group who lost a mean of 3.5 +/- 12.8 lb (median = -4 lb). Twenty-six subjects (63%) in the intervention group maintained or gained weight compared with 32 subjects (42%), in the nonintervention group. CONCLUSION: The results of this study suggest that nutrition intervention in HIV-infected persons can improve nutritional status and may lead to an enhanced ability to fight infection.

Endocrine function in the HIV wasting syndrome.

We compared endocrine function in patients with the HIV wasting syndrome with other HIV-positive patients without wasting to determine associations between endocrine dysfunction and wasting. Sixty-six HIV-seropositive patients were evaluated by thyroid, gonadal, and adrenal function tests. Fourteen of these patients met the clinical definition of wasting. Total and free testosterone levels were significantly lower in patients with wasting compared with patients without wasting with both similar and higher mean CD4 counts. Prolactin levels were significantly higher, and cortisol levels were higher with borderline significance in patients with wasting compared with patients with similar CD4 counts without wasting. These findings suggest that endocrine function in the HIV wasting syndrome differs from that of HIV-infected patients without wasting, which may have implications about the pathogenesis and treatment of the HIV wasting syndrome.

[A case of severe juvenile pulmonary tuberculosis associated with malnutrition in special reference to nutritional assessment].

We reported a case who had suffered from severe pulmonary tuberculosis in association with severe malnutrition. A 19-year-old man was admitted complaining of high fever, productive cough and body weight loss. Before admission, he worked as a cook for long hours a day and had meals irregularly. On admission, he was cachexic. Coarse crackles were auscultated on the both lung field, and the liver was enlarged. Chest X-ray revealed multiple ringed and mottled shadows mainly in bilateral upper and middle lung field. Laboratory examination revealed inflammatory reaction defined by an increase of white blood cells, accelerated erythrocyte sedimentation rate and positive CRP, impairment of liver function and cell-mediated immunity, hypoxemia and restrictive lung dysfunction. Ziehl-Neelsen stain of sputum showed a large number of acid fast bacilli. The assessment of his nutritional status showed decrease in anthropometric measurements, visceral proteins and the Fischer ratio, which suggested that he was in the status of protein-calorie malnutrition in association with amino acid imbalance. He was treated with nutritional therapy in addition to antituberculous drugs, which improved his clinical symptoms, laboratory data and nutritional assessment. These results suggested the importance of nutritional assessment and nutritional therapy based on it.

Hypoglycaemia associated with anorexia nervosa.

A 41 year old woman with severe emaciation due to longstanding anorexia nervosa presented with recurrent hypoglycaemia. During an episode of hypoglycaemia, serum insulin and C peptide were undetectable and plasma beta hydroxybutyrate, free fatty acids and lactate were inappropriately low. Response to intravenous glucagon was poor. Muscle enzymes were grossly elevated until she gained weight. Hypoglycaemia was abolished by weight gain.
