A naturalistic study of plasma lipid alterations in female patients with anorexia nervosa before and after weight restoration treatment.

BACKGROUND: Plasma lipid concentrations in patients with anorexia nervosa (AN) seem to be altered. METHODS: We conducted a naturalistic study with 75 adult female patients with AN and 26 healthy female controls (HC). We measured plasma lipid profile, sex hormones and used self-report questionnaires at admission and discharge. RESULTS: Total cholesterol (median (IQR): 4.9 (1.2)) and triglycerides (TG) (1.2 (0.8)) were elevated in AN at admission (BMI 15.3 (3.4)) compared with HC (4.3 (0.7), p = 0.003 and 0.9 (0.3), p = 0.006) and remained elevated at discharge (BMI 18.9 (2.9)) after weight restoration treatment. Estradiol (0.05 (0.1)) and testosterone (0.5 (0.7)) were lower in AN compared with HC (0.3 (0.3), p = < 0.001 and 0.8 (0.5), p = 0.03) and remained low at discharge. There was no change in eating disorder symptoms. Depression symptoms decreased (33 (17) to 30.5 (19), (p = 0.007)). Regression analyses showed that illness duration was a predictor of TG, age was a predictor of total cholesterol and LDL, while educational attainment predicted LDL and TG. CONCLUSION: Lipid concentrations remained elevated following weight restoration treatment, suggesting an underlying, premorbid dysregulation in the lipid metabolism in AN that persists following weight restoration. Elevated lipid concentrations may be present prior to illness onset in AN. LEVEL OF EVIDENCE: III: Evidence obtained from well-designed cohort or case-control analytic studies.

Fat is essential for the human body. Too much fat in the blood can be a sign of underlying illness including heart disease. This study investigated how plasma lipids (fats) are affected in individuals with anorexia nervosa (AN). We included 75 adult female individuals with AN and 26 healthy female controls, and measured lipids, sex hormones, and used questionnaires upon admission and discharge from treatment. We found that low-weight individuals with AN had higher lipids than the healthy controls, and these lipids remained elevated after weight restoration treatment. Additionally, individuals with AN had lower levels of sex hormones (estradiol and testosterone) at their low weight, and they stayed low even after weight restoration treatment. Eating disorder symptoms remained unchanged, but depression symptoms decreased during treatment. In conclusion, the study suggests that individuals with AN have changes in their lipid metabolism, which persists even after weight restoration treatment. We don't know the reason behind these elevated lipids, and therefore, this should be investigated further in future study.

Elevated lipid class concentrations in females with anorexia nervosa before and after intensive weight restoration treatment-A lipidomics study.

OBJECTIVE: To study the plasma lipidome of patients with anorexia nervosa (AN) before and after weight restoration treatment and report associations with AN subtypes and oral contraceptive pill (OCP) usage. METHODS: Quantitative shotgun lipidomics analysis was used to study plasma lipids of 50 female patients with AN before and after weight restoration treatment and 50 healthy female controls (HC). The AN group was assessed with blood samples and questionnaires before and after weight restoration. RESULTS: In total we quantified 260 lipid species representing 26 lipid classes of which 13 lipid class concentrations were elevated in patients with AN at admission compared with HC. Lipid classes remained elevated after weight restoration treatment of 84 days (median; interquartile range 28), and only the concentration of the ceramide lipid class increased between pre- and post-treatment (p = .03), whereas lysophosphatidylcholine (LPC, p = .02), ether-linked Phosphatidylcholine (LPCO, p = .02), and lysophosphatidylethanolamine (LPE, p = .009) decreased. CONCLUSION: In AN, 13 out of 26 lipid class concentrations were elevated at admission and remained elevated post-treatment. Ceramides increased further between pre- and post-weight restoration treatment, which could be related to the rapid weight gain during re-nutrition. Further research is needed to elucidate the effects of weight restoration treatment on short- and long-term lipid profiles in individuals with AN. PUBLIC SIGNIFICANCE STATEMENT: Lipidomics research can increase the understanding of AN, a complex and potentially life-threatening eating disorder. By analyzing lipids, or fats, in the body, we can identify biological markers that may inform diagnosis and develop more effective treatments. This research can also shed light on the underlying mechanisms of the disorder, leading to a better understanding of the processes involved in eating behavior.

Acupuncture-Induced Tension Pneumothorax Presenting as Acute Heart Failure.

Takotsubo syndrome (TSS) is a reversible, acute cardiomyopathy with transient heart failure, often secondary to other disorders. A 64-year-old woman, with no history of ischemic heart disease, was admitted to the emergency department after developing sudden-onset dyspnea after a planned acupuncture treatment for back pain. Acute echocardiography showed decreased left ventricular function with basal hypercontraction and apical akinesia and was interpreted, and treated, as acute heart failure. When the attending cardiologist arrived, the patient still had dyspnea with a declining blood pressure (97/65 mmHg) and tachycardia (111/minute). The cardiologist suspected a tension pneumothorax induced by the penetration of an acupuncture needle to the apex of the lung, as well as secondary TSS cardiomyopathy. An acute chest X-ray was performed, which showed a large left-sided rim pneumothorax. The attending surgeon placed a chest tube in the left 6th intercostal space in the midaxillary line, and the patient reported immediate pain relief and improvement in her dyspnea. The patient's clinical condition improved, and a control X-ray showed that the lung was fully expanded. The chest tube was removed, but after a few minutes, the patient developed a massive subcutaneous emphysema in the upper chest and in the face and her clinical condition deteriorated rapidly. A new chest tube was inserted, and the patient's tachycardia diminished, with her clinical condition improving immediately. The patient remained hospitalized for the next seven days. After three continuous days without any escaped air in the chest tube, the tube was removed, and the patient was observed for another 48 hours. This time, the removal was without any complications and within two days, the patient was ready for discharge. The follow-up echocardiography showed complete recovery of left ventricular function.

Case report: cognitive performance in an extreme case of anorexia nervosa with a body mass index of 7.7.

BACKGROUND: Studies show that adult patients with anorexia nervosa display cognitive impairments. These impairments may be caused by illness-related circumstances such as low weight. However, the question is whether there is a cognitive adaptation to enduring undernutrition in anorexia nervosa. To our knowledge, cognitive performance has not been assessed previously in a patient with anorexia nervosa with a body mass index as low as 7.7 kg/m2. CASE PRESENTATION: We present the cognitive profile of a 35-year-old woman with severe and enduring anorexia nervosa who was diagnosed at the age of 10 years. She was assessed with a broad neuropsychological test battery three times during a year. Her body mass index was 8.4, 9.3, and 7.7 kg/m2, respectively. Her general memory performance was above the normal range and she performed well on verbal and design fluency tasks. Her working memory and processing speed were within the normal range. However, her results on cognitive flexibility tasks (set-shifting) were below the normal range. CONCLUSIONS: The case study suggests that it is possible to perform normally cognitively despite extreme and chronic malnutrition though set-shifting ability may be affected. This opens for discussion whether patients with anorexia nervosa can maintain neuropsychological performance in spite of extreme underweight and starvation.

Increased lipid and lipoprotein concentrations in anorexia nervosa: A systematic review and meta-analysis.

OBJECTIVE: Alterations in blood lipid concentrations in anorexia nervosa (AN) have been reported; however, the extent, mechanism, and normalization with weight restoration remain unknown. We conducted a systematic review and a meta-analysis to evaluate changes in lipid concentrations in acutely-ill AN patients compared with healthy controls (HC) and to examine the effect of partial weight restoration. METHOD: A systematic literature review and meta-analysis (PROSPERO: CRD42017078014) were conducted for original peer-reviewed articles. RESULTS: Forty-eight studies were eligible for review; 33 for meta-analyses calculating mean differences (MD). Total cholesterol (MD = 22.7 mg/dL, 95% CI = 12.5, 33.0), high-density lipoprotein (HDL; MD = 3.4 mg/dL, CI = 0.3, 7.0), low-density lipoprotein (LDL; MD = 12.2 mg/dL, CI = 4.4, 20.1), triglycerides (TG; MD = 8.1 mg/dL, CI = 1.7, 14.5), and apolipoprotein B (Apo B; MD = 11.8 mg/dL, CI = 2.3, 21.2) were significantly higher in acutely-ill AN than HC. Partially weight-restored AN patients had higher total cholesterol (MD = 14.8 mg/dL, CI = 2.1, 27.5) and LDL (MD = 16.1 mg/dL, CI = 2.3, 30.0). Pre- versus post-weight restoration differences in lipid concentrations did not differ significantly. DISCUSSION: We report aggregate evidence for elevated lipid concentrations in acutely-ill AN patients compared with HC, some of which persist after partial weight restoration. This could signal an underlying adaptation or dysregulation not fully reversed by weight restoration. Although concentrations differed between AN and HC, most lipid concentrations remained within the reference range and meta-analyses were limited by the number of available studies.

OBJETIVO: En la anorexia nervosa (AN) han sido reportadas alteraciones en las concentraciones de lípidos sanguíneos; sin embargo, la extensión, mecanismo y normalización con la restauración del peso continúa aún desconocida. Hicimos una revisión sistemática y meta-análisis para evaluar los cambios en las concentraciones de lípidos en pacientes agudamente enfermas de AN comparados con controles sanos (HC) y para examinar el efecto parcial de la restauración de peso. MÉTODO: Una revisión sistemática de la literatura y meta-análisis (PROSPERO: CRD42017078014) fueron llevados a cabo en artículos originales revisados por pares. RESULTADOS: Un total de cuarenta y ocho estudios fueron elegibles para revisión; 33 para meta-análisis calculando las diferencias promedio (MD). Colesterol total (MD = 22.7 mg/dL, 95% CI = 12.5, 33.0), lipoproteína de alta densidad (HDL; MD = 3.4 mg/dL, CI = 0.3, 7.0), lipoproteína de baja densidad (LDL; MD = 12.2 mg/dL, CI = 4.4, 20.1), triglicéridos (TG; MD = 8.1 mg/dL, CI = 1.7, 14.5), y apolipoproteína B (Apo B; MD = 11.6 mg/dL, CI = 2.3, 21.2) fueron significativamente elevados en los pacientes agudamente enfermos de AN en comparación con los controles sanos (HC). Los pacientes con AN parcialmente recuperados de peso tuvieron niveles más elevados de colesterol total (MD = 14.8 mg/dL, CI = 2.1, 27.5) y de LDL (MD = 16.1 mg/dL, CI = 2.3, 30.0). Las diferencias pre- versus post- restauración de peso en las concentraciones de lípidos no difirieron significativamente. DISCUSIÓN: Reportamos evidencia agregada de concentraciones elevadas de lípidos en pacientes agudamente enfermos de AN comparados con controles sanos (HC), algunos de los cuales persisten después de la restauración parcial de peso. Esto podría señalar una adaptación subyacente o desregulación no completamente revertida por la restauración del peso. Aunque las concentraciones difirieron entre AN y HC, la mayoría de las concentraciones de lípidos permanecieron dentro del rango de referencia y los meta-análisis fueron limitados por el número de estudios disponibles.

Effect of Two Techniques of Parental Interaction on Children's Anxiety at Induction of General Anaesthesia-A Randomized Trial.

OBJECTIVE: Several non-pharmacological techniques, such as parental presence and behavioral preparation, are used to decrease children's anxiety at anaesthesia induction. We compared the mean anxiety score in children at the time of anaesthesia induction with two different physical techniques of parental interaction and a control group with no parent present. The secondary objective was to determine the face mask acceptance during induction. METHODS: This study recruited 123 ASA I & II children, aged 1 to 8 years, undergoing day care surgery, who were randomly allocated to three groups. Children either went to the operating room (OR) alone (Gp C), or one parent sat next to the child at induction (Gp PS), or the child sat in parent's lap (Gp PH). The anxiety score on the modified Yale Preoperative Anxiety Scale (mYPAS) was recorded in the preinduction area of OR and at the induction of anaesthesia before the face mask application. A cut-off value of less than 30 indicated low anxiety. The face mask acceptance was also rated. RESULTS: All patients had the mYPAS scores higher than 30 in the preinduction area with no significant difference between groups. Prior to induction, the Gp C score was significantly high as compared to Gp PS (p=0.016) and Gp PH (p=0.001), but it was not different between the Gp PS and PH (p=1.00). The face mask acceptance was easy in 4.9 % patients in Gp C, 26.8% in Gp PS, and 56% in Gp PH. CONCLUSION: Parental presence during induction did not prevent children's anxiety, but it reduced it, irrespective of the physical technique used. The face mask acceptance was better in Gp PH.

Reconstruction of Extensive Post-Electric Burn Scalp Defects With Exposed Bones: A Study of 12 Cases.

The scalp is a unique part of the human body with respect to its shape and position. It is the part of the body that is usually exposed in its original form, with no covering by any means of clothing. In workplaces, especially in the electrical industry in the area of electrical substations and power transmission lines it is this part of the body that can easily come in contact with high tension electrical wires. Others who can be prone to suffer such injuries are pedestrians, people working on heights, ladies hanging clothes on terraces.This case series includes 12 patients who sustained high-voltage electric burn injury to the scalp. Of the reconstructive options used, 2 were free flaps, 1 was a distant flap, and 9 were local flaps. Of the 2 free flaps, there was loss of 1 free flap due to thrombosis, which was later reconstructed with extracorporeal radial forearm flap.Of the 9 local flaps, therewas partial flap necrosis in 2 cases, which required debridement and the wounrds healed secondarily. There was recurrent osteomyelitis in 1 patient who underwent sequestrectomy. In conclusion, the results obtained, in all the patients, were satisfactory without necessitating a bony reconstruction.

[The refeeding syndrome in anorexia nervosa].

The refeeding syndrome (RFS) is a potentially fatal condition involving fluid and electrolyte imbalances after refeeding in patients with anorexia nervosa. Low-calorie diet added thiamine and minerals is the standard approach to prevent RFS. In a recent systematic review starting with a higher calorie amount than earlier has been recommended, and in another review, it is proposed that a restriction in the amount of carbohydrates may allow for a higher calorie intake early on to enable a safe and faster weight gain. There are still many unanswered questions, but these studies may point to a future change in the guidelines.

Incidence of cesarean section and analysis of risk factors for failed conversion of labor epidural to surgical anesthesia: A prospective, observational study in a tertiary care center.

BACKGROUND AND AIMS: This study aimed to analyze the effect of labor epidural (LE) on the incidence of cesarean section (CS) and assess the risk factors involved in failed conversion of LE to surgical anesthesia for CS. MATERIAL AND METHODS: A prospective observational study of 18 months from January 2012 to June 2013 was conducted on all patients who had delivered in the labor room suit of our hospital. The data collected for all 4694 patients included their demographics, parity and mode of delivery. In addition a predesigned proforma, with additional information was used for 629 parturient with LE. RESULTS: During the study period, total numbers of deliveries performed in our hospital were 4694, with an epidural rate of 13.4% (629/4694). No significant difference (P = 0.06) was observed in the rate of CS among women with or without LE (28 % [n = 176/629] vs. 31.7 % [n = 1289/4065]), however, a statistically significant difference (P < 0.01) was observed in the rate of assisted delivery in patients receiving LE as compared to those delivering without it (8.7% [n = 55/629] vs. n = 3.7% [154/4065]). For 176 patients requiring CS, LE utilization for surgical anesthesia was 52.8% (93/176) and factors identified for not utilizing LE in 47% (83/176) were; failure to achieve surgical anesthesia in 6.8% (12/176), emergency CS in 28.4% (50/176), patient preference in 6.8% (12/176) and inadequate labor pain relief with LE in 5.1% (9/176) patients. Non-obstetric anesthesiologists were involved in 59% (49/83) of cases where LE was not used for CS. CONCLUSION: LE had no effect on the rate of CS; however it significantly increased (P < 0.01) the rate of assisted delivery. Factors like inadequate LE, emergency situations and non-obstetric anesthesiologists can all be responsible for failed conversion of LE to surgical anesthesia for CS.

Optical coherence tomography in the diagnosis of basal cell carcinoma.

Since its introduction in dermatology in the late 1990s optical coherence tomography (OCT) has been used to study many skin diseases, in particular non-melanoma skin cancer and it s precursors. Special attention has been paid to superficial basal cell carcinoma (BCC), and a number of smaller observational studies have been published. The diagnostic criteria for BCC of these studies are systematically reviewed. A systemic review of English language studies was performed using PubMed, Google Scholar and Royal Danish Library, to search for primary papers on OCT and BCC. The references of retrieved papers were searched by hand for further relevant papers. A total of 39 papers were identified (search date: 2014-01-15). 22 were excluded because they did not meet the inclusion criteria, leaving 17 papers for analysis. In 100% of the studies, rounded dark structures in the upper dermis surrounded by a hyperreflective halo possibly surrounded by a hyporeflective border and disruption of epidermal layering were described. In 53% of the reports a hyporeflective lateral tumour border was described. A range of other features were mentioned in a minority of the studies. It is suggested that these diagnostic criteria could be characteristic for identifying BCC lesions using OCT.

The stem cell organisation, and the proliferative and gene expression profile of Barrett's epithelium, replicates pyloric-type gastric glands.

OBJECTIVE: Barrett's oesophagus shows appearances described as 'intestinal metaplasia', in structures called 'crypts' but do not typically display crypt architecture. Here, we investigate their relationship to gastric glands. METHODS: Cell proliferation and migration within Barrett's glands was assessed by Ki67 and iododeoxyuridine (IdU) labelling. Expression of mucin core proteins (MUC), trefoil family factor (TFF) peptides and LGR5 mRNA was determined by immunohistochemistry or by in situ hybridisation, and clonality was elucidated using mitochondrial DNA (mtDNA) mutations combined with mucin histochemistry. RESULTS: Proliferation predominantly occurs in the middle of Barrett's glands, diminishing towards the surface and the base: IdU dynamics demonstrate bidirectional migration, similar to gastric glands. Distribution of MUC5AC, TFF1, MUC6 and TFF2 in Barrett's mirrors pyloric glands and is preserved in Barrett's dysplasia. MUC2-positive goblet cells are localised above the neck in Barrett's glands, and TFF3 is concentrated in the same region. LGR5 mRNA is detected in the middle of Barrett's glands suggesting a stem cell niche in this locale, similar to that in the gastric pylorus, and distinct from gastric intestinal metaplasia. Gastric and intestinal cell lineages within Barrett's glands are clonal, indicating derivation from a single stem cell. CONCLUSIONS: Barrett's shows the proliferative and stem cell architecture, and pattern of gene expression of pyloric gastric glands, maintained by stem cells showing gastric and intestinal differentiation: neutral drift may suggest that intestinal differentiation advances with time, a concept critical for the understanding of the origin and development of Barrett's oesophagus.

Iodinated contrast opacification gradients in normal coronary arteries imaged with prospectively ECG-gated single heart beat 320-detector row computed tomography.

BACKGROUND: To define and evaluate coronary contrast opacification gradients using prospectively ECG-gated single heart beat 320-detector row coronary angiography (CTA). METHODS AND RESULTS: Thirty-six patients with normal coronary arteries determined by 320 x 0.5-mm detector row coronary CTA were retrospectively evaluated with customized image postprocessing software to measure Hounsfield Units at 1-mm intervals orthogonal to the artery center line. Linear regression determined correlation between mean Hounsfield Units and distance from the coronary ostium (regression slope defined as the distance gradient G(d)), lumen cross-sectional area (G(a)), and lumen short-axis diameter (G(s)). For each gradient, differences between the 3 coronary arteries were analyzed with ANOVA. Linear regression determined correlations between measured gradients, heart rate, body mass index, and cardiac phase. To determine feasibility in lesions, all 3 gradients were evaluated in 22 consecutive patients with left anterior descending artery lesions > or =50% stenosis. For all 3 coronary arteries in all patients, the gradients G(a) and G(s) were significantly different from zero (P<0.0001), highly linear (Pearson r values, 0.77 to 0.84), and had no significant difference between the left anterior descending, left circumflex, and right coronary arteries (P>0.503). The distance gradient G(d) demonstrated nonlinearities in a small number of vessels and was significantly smaller in the right coronary artery when compared with the left coronary system (P<0.001). Gradient variations between cardiac phases, heart rates, body mass index, and readers were low. Gradients in patients with lesions were significantly different (P<0.021) than in patients considered normal by CTA. CONCLUSIONS: Measurement of contrast opacification gradients from temporally uniform coronary CTA demonstrates feasibility and reproducibility in patients with normal coronary arteries. For all patients, the gradients defined with respect to the coronary lumen cross-sectional area and short-axis diameters are highly linear, not significantly influenced by the coronary artery (left anterior descending artery versus left circumflex versus right coronary artery), and have only small variation with respect to patient parameters. Preliminary evaluation of gradients across coronary artery lesions is promising but requires additional study.
