We investigate the Casimir effect in the context of a nontrivial topology by means of a generalized Matsubara formalism. This is performed in the context of a scalar field in D Euclidean spatial dimensions with d compactified dimensions. The procedure gives us the advantage of considering simultaneously spatial constraints and thermal effects. In this sense, the Casimir pressure in a heated system between two infinite planes is obtained and the results are compared with those found in the literature.

Aquifers can be defined as complex ecological systems. Their description is closely influenced by geometrical and geological parameters, which portray the hydrogeological behaviour of underground systems. This paper reports a contribution to assessing groundwater contamination risk in a particular Sicily sector, where deterministic approaches have methodically assessed and mapped vulnerability and quality of groundwater. In detail, in the coastal area of Acquedolci (Northern Sicily), already intensely surveyed in the frame of interdisciplinary projects on geological risk, implementing models and systems have been experimented, also considering fuzzy logic. Cartography issues are here presented and compared, with particular regard to the effect of stochastic hydrogeological elements (i.e. “depth to water”), locally characterized by variability for simultaneous climate, overdraft, irrigation and sea encroachment. The authors show how fuzzy logic, applied to vulnerability settings, contributes to a better comprehension of the passive scenery offered by aquifers in Acquedolci Sicily area.

Introduction: Thyroid states can be associated with psychiatric manifestations, be it hypothyroid, hyperthyroid or even euthyroid. The effect of depression is significant in subclinical hypothyroidism. Sometimes, its signs and symptoms are indistinguishable from Major Depressive Disorder. Our immunological system and early embryologic origins also play a role in the coexistence of other comorbidities like Pernicious Anemia. Case: A 35-year-old Hispanic female presented with significant low mood, somnolence, weight gain, increased hunger, cold intolerance and epigastric pain. It is important to note the variety of clinical manifestations of our hypothyroidism patient to understand its associations and help us with a better approach to treatment. Discussion: Standard approaches to treatment of Subclinical Hypothyroidism will depend mostly on laboratory findings such as TSH levels and free T4. Individualized therapy chosen for our patient was based on his mood symptoms, laboratory findings and coexistence of Pernicious Anemia. The use of daily 0.025 mg of levothyroxine, 10 mg of escitalopram oxalate and weekly injections of cyanocobalamin were treatments of choice. Conclusion: During follow up of our patient, we can conclude that Levothyroxine and Escitalopram Oxalate were able to improve hypothyroidism symptoms, reduce thyroglobulin and peroxidase antibodies and improve mood symptoms including cognitive functions. In addition to this, weekly cyanocobalamin injections were integrated into the management. As parietal cell antibodies decreased, gastrointestinal symptoms also disappeared. By addressing the concerns of our patient, we improved quality of care, and this is reflected in the patient’s wellbeing in physical and psychological.

AIM:To evaluate gallstone incidence and risk factors in a large population-based study. METHODS: Gallstone incidence and risk factors, were evaluated by structured questionnaire and physical examination, respectively, in 9611 of 11 109 (86.5%) subjects who were gallstone-free at the cross-sectional study. RESULTS: Six centers throughout Italy enrolled 9611 subjects (5477 males, 4134 females, aged 30-79 years), 9517 of whom were included into analysis: 424 subjects (4.4%) had gallstones and 61 (0.6%) had been cholecystectomized yielding a cumulative incidence of 0.67% per year (0.66% in males, 0.81% in females). Increasing age, a high body mass index (BMI), a history of diabetes, peptic ulcer and angina, and low cholesterol and high triglyceride levels were identifi ed as risk factors in men while, in females, the only risk factors were increasing age and a high *** age and pain in the right hypocondrium in men and increasing age in females were identifi ed as predictors of gallstones. Pain in the epigastrium/ right hypocondrium was the only symptom related to gallstones; furthermore, some characteristics of pain (forcing to rest, not relieved by bowel movements) were significantly associated with gallstones. No correlation was found between gallstone characteristics and clinical manifestations, while increasing age in men and increasing age and BMI in females were predictors of pain. CONCLUSION:Increasing age and BMI represent true risk factors for gallstone disease (GD); pain in the right hypocondrium and/or epigastrium is confi rmed as the only symptom related to gallstones.
