RESUMO
OBJECTIVE: Most people with type 2 diabetes (T2DM) and nonalcoholic steatohepatitis (NASH) or advanced fibrosis (AF) remain undiagnosed, resulting in missed opportunities for early intervention. This multicenter, prospective study assessed the yield of using routinely available data to identify these patients. RESEARCH DESIGN AND METHODS: A total of 713 outpatients with T2DM, screened in four diabetology clinics for nonalcoholic fatty liver disease according to American Diabetes Association criteria, were referred to hepatologists for further work-up (Fibrosis-4 and vibration-controlled transient elastography [VCTE]). A liver biopsy was proposed when ALT levels were persistently >20 IU/L in female patients or >30 IU/L in male patients, in the absence of other liver disease. RESULTS: Liver biopsies were performed in 360 patients and considered adequate for reading after central review for 330 specimens (median patient age, 59 years; male patients, 63%; median BMI and HbA1c values, 32 and 7.5%, respectively). Prevalence of NASH, AF, and cirrhosis were 58%, 38%, and 10%, respectively. Liver lesions were independently associated with the components of metabolic syndrome but not with the micro- and macrovascular complications of T2DM. Models based on routinely available data with or without VCTE had good accuracy to predict AF (respectively: area under the receiver operating characteristic curve [AUROC], 0.84 and 0.77; and correctly classified 59% and 45%) and NASH (respectively: AUROC, 0.82 and 0.81; 44% and 42%). CONCLUSIONS: Despite the use of a low ALT threshold, prevalence of NASH (58%) or AF (38%) was high. Routinely available data had a high yield in identifying patients with T2DM with AF and/or NASH requiring further liver assessment.

We report the case of a 36-year-old woman who developed non-diabetic ketoacidosis following a low carbohydrate diet in order to lose weight while actively breast feeding her newborn. She was admitted in intensive care unit because of severe metabolic acidosis. She rapidly recovered after refeeding process. Lactation ketoacidosis, a special condition that occurs in non-diabetic breastfeeding women, is rare and life-threatening. This report highlights the importance of nutritional education of lactating women in the post-partum period.

People suffering from extreme obesity may be exposed to delayed diagnosis and treatment of cancer. A 37-year-old woman (weight = 245 kg, body mass index (BMI) = 79 kg/m2), presented a sepsis associated with nonspecific abdominal pain for 4 months. After several unsuccessful attempts due to her weight and a large waist circumference, abdominal CT scan was finally successfully performed and showed a large retroperitoneal mass. An ultrasound-guided core needle biopsy was performed and was in favor of a liposarcoma. Surgery was performed to remove the entire tumor of an estimated weight of 98 kg, a giant retroperitoneal dedifferentiated liposarcoma. This case highlights the difficulties to screen, diagnose, and manage cancers encountered in patients suffering from massive obesity.

Due to its physical and chemical properties, the n-type tungsten oxide (WO3) semiconductor is a suitable photoanode for water decomposition reaction. The responses of the photoelectrochemical PEC water-splitting properties as an effect of structural and optical changes of WO3 thin films, as well as the nature of electrolyte solutions, were studied in this work. The WO3 thins films have been obtained by pulsed laser deposition (PLD) on silicon (Si(001)) covered with platinum substrates using three different laser wavelengths. As the XRD (X-ray diffraction) and XTEM (cross-section transmission electron microscopy) analysis shows, the formation of highly crystalline monocline WO3 phase is formed for the film deposited at 1064 nm wavelength and poor crystalline phases with a large ordering anisotropy, characteristic of 2D structures for the films deposited at 355 nm and 193 nm wavelengths, respectively. The photogenerated current densities Jph depend on the laser wavelength, in both alkaline and acidic electrolyte. The maximum values of the photocurrent density have been obtained for the sample prepared with laser emitting at 355 nm. This behavior can be correlated with the coherent crystallized atomic ordering that appear for long distances (10-15 nm) in the (001) plane of the monoclinic WO3 phase structure films obtained at 355 nm laser wavelength. All the samples show poor current density in dark conditions and they are very stable in both acidic and alkaline solutions. The highest photocurrent density value is obtained in acidic solution for the WO3 thin film prepared by 355 nm laser (29 mA/cm2 at 1.6 V vs. RHE (1.35 V vs. Ag/AgCl)).
RESUMO
Nonalcoholic fatty liver disease (NAFLD) is strongly associated with obesity and insulin resistance. There is currently no pharmacological treatment validated in steatosis. The combination of weight loss and adequate physical activity can improve liver steatosis. In randomized trials and cohort studies, a weight loss of at least 7% and a diet approaching the Mediterranean diet have been associated with an improvement in hepatic fat content, an improvement in hepatic biomarkers, and regression of histological signs of steatosis. Bariatric surgery by losing weight can lead to an improvement in hepatic fat content.

INTRODUCTION: Hypothyroidism has been associated with mood disorders but some cases of acute psychosis have also been reported. However, less attention has been paid to suicidal behavior in these patients. CASE REPORT: We report a case of suicide attempt by self-stabbing in a 43-year-old woman without past psychiatric history, four months after radioiodine therapy for Graves' disease. On clinical examination remarkable signs of myxedema were found and blood investigations showed hypothyroidism with an extremely high thyroid stimulating hormone (TSH) level (152 mUI/L; reference range 0.20-5.10). The patient presented delirium symptoms at the time of self-stabbing, which was associated with persecutory delusions and auditory harm command hallucinations. A rapid physical and psychiatric improvement was observed after the initiation of an oral thyroid replacement therapy without relapse after early discontinuation of the antipsychotic treatment. DISCUSSION: The most distinctive feature of our case is that the violent suicide attempt could be attributed to the myxedema psychosis. Suicide may result from several factors, including psychosocial stressors, psychiatric symptoms, and hormonal disturbance. This unique presentation should remind clinicians to systematically consider ordering additional tests in patients with atypical psychiatric presentation, even when serious behavioral disorders (such as violent suicide attempts) are present and may result in premature transfer to psychiatric units.

RESUMO
BACKGROUND: The perception of self-discrepancies between the actual self and the ideal self has been defined as a cognitive risk factor for depression (Higgins, 1987). In this view, self-discrepancy monitoring (SDM) refers to the voluntary re-orientation of attention towards detecting discrepancies between ideal and actual selves, even in a positive situation. AIMS: The goal of this study was to explore the impact of SDM on levels of mood in the face of positive stimuli. METHOD: Two clinical and two non-clinical samples were recruited from two different European countries (Italy and Romania). All participants were asked to focus on a past positive experience, and were then randomly allocated to one of two induction tasks. The experimental condition consisted of monitoring discrepancies between personal goals and the recalled positive experience, while the control condition consisted of observing what the participant was feeling. RESULTS: The findings show that, after recalling a positive memory, SDM leads to a significant decrease in mood over a short period independent of the severity of depressive symptoms. This effect is partially mediated by the concurrent change in levels of brooding. CONCLUSIONS: Self-discrepancy monitoring in response to positive stimuli tends to lower current mood independent of the initial level of depressive symptoms, and seems to be a global trigger of emotional distress that does not refer only to a depressed cognitive style.
