Credit crunch: analisi e possibili soluzioni

La seconda fase della grande crisi finanziaria iniziata nel 2010, c.d. del debito so-vrano, ha pesantemente colpito le banche italiane, determinando dal 2011 una si-tuazione di credit crunch per famiglie e imprese. L’obiettivo del presente contributo è di analizzare come il credit crunch stia determinando una situazione di disintermediazione, ormai strutturale, del canale bancario per il credito alle imprese, modificando il tradizionale rapporto banca-impresa in Italia. Come conseguenza occorre individuare e implementare azioni volte a intervenire sull’assetto complessivo del nostro sistema finanziario per porre rimedio a severe carenze strutturali in termini di strumenti, mercati e intermediari

Serum fatty acids and risk of cutaneous melanoma: a population-based case-control study

Background. Some observational studies have suggested that excess dietary intake of polyunsaturated fatty acids such as linoleic acid increases cutaneous melanoma risk. We aimed at examining the association between serum fatty acids and melanoma risk by conducting a population-based case-control study in a northern Italy community. Methods. \ue062e percentage composition of 12 fatty acids was determined in 51 newly diagnosed melanoma patients and 51 age- and sex-matched population controls by extracting total lipids from serum samples using thin layer and gas chromatography. Conditional logistic regression was used to estimate the relative risk of melanoma associated with tertiles of percentage composition of each fatty acid as well as groupings including saturated, monounsaturated, and polyunsaturated fatty acids. Results. We found a slightly increased melanoma risk for stearic and arachidic acids proportion, with and without adjustment for potential confounders. For an n-3 polyunsaturated fatty acid, docosapentaenoic acid, we found a male-specic direct association with melanoma risk. o other associations emerged for the other saturated, monounsaturated, and polyunsaturated fatty acids, individually or grouped by type. Conclusions. These fndings do not suggest a major role of fatty acids, including linoleic acid, on risk of cutaneous melanoma, though their evaluation is limited by the small sample size

A challenging case of pregnancy with placenta accreta and very rare irregular antibodies versus Cromer blood group system: a case report

ntroduction: This report describes the challenges of treating a pregnant woman who had a rare case of critical placenta accreta with concurrent Cromer system anti-Tc(a) and anti-Kidd A alloantibodies. No previous case of such alloimmunization in a patient with placenta accreta has been reported. Case presentation: A 28-year-old African woman with anti-Cromer Tc(a) antibodies, anti-Kidd A antibodies and placenta accreta was admitted to the obstetric emergency department at our university hospital with persistent vaginal bleeding. Her rare Cromer blood group system antibodies had been diagnosed 1 month earlier; no compatible blood had been found despite a worldwide search. We performed a cesarean section after placement of Fogarty balloons in her uterine arteries with preoperative endovascular interventional radiology. Other therapeutic interventions included preoperative iron administration to raise hemoglobin and the scheduled predeposit of autologous blood. Intraoperative therapeutic management was aimed at preventing coagulopathy and massive bleeding. With the use of alternative medical techniques determined during perioperative planning, her intraoperative blood loss was only 1000mL, despite the placenta accreta. She was discharged from the hospital 4 days after cesarean section. Conclusions: To the best of our knowledge, this is the first report of an alloimmunized patient with two different alloantibodies and concurrent high risk of bleeding because of placenta accreta. The close collaboration among obstetricians, anesthesiologists, interventional radiologists, blood bank pathologists and intensive care doctors prevented serious consequences in this patient. The exceptional feature of this case is the patient's double risk: the placenta accreta and the inability to transfuse compatible blood. These two extreme situations challenged the multidisciplinary medical team

Hereditary pancreatic cancer: A retrospective single-center study of 5143 Italian families with history of BRCA-related malignancies

The identification of BRCA mutations plays a crucial role in the management of hereditary cancer prevention and treatment. Nonetheless, BRCA-testing in pancreatic cancer (PC) patients is not universally introduced in clinical practice. A retrospective analysis was conducted, firstly, to evaluate the rate of BRCA-positive families among those presenting a family history of PC besides breast and/or ovarian cancer. Secondly, the relationship between BRCA pathogenic variants and PC risk was evaluated. Finally, the characteristics of PC developed in BRCA families were described. Among 5143 family trees reporting breast and/or ovarian cancer cases, 392 showed a family history of PC. A total of 35 families (24.5% selected by the Modena Criteria and 21.3% by the NCCN Criteria) were positive to BRCA testing. Among the BRCA1 mutations, 36.8% were found within a region defined by c.3239\u2013c.3917, whilst 43.7% of BRCA2 mutations were located within c.7180\u2013c.8248. This study confirmed that an increase in the rate of positive tests in families with PC when associated to breast and/or ovarian tumors. Moreover, this analysis indicated two possible Pancreatic Cancer Cluster Regions that should be verified in future research. Finally, PC in families with breast and/or ovarian cancer history, particularly in BRCA families, were diagnosed at younger age and showed better one-year overall survival

Because of large intra-individual variation in hormone levels, few studies have investigated the relation of serum sex hormones to breast cancer (BC) in premenopausal women. We prospectively studied this relation, adjusting for timing of blood sampling within menstrual cycle. Premenopausal women (5,963), recruited to the Hormones and Diet in the Etiology of Breast Tumors (ORDET) cohort study, provided a blood sample in the 20 -24th day of their menstrual cycle. The hypothesis that breast cancer (BC) is related to ovarian function dates back over a century. 1 Epidemiological, in vitro and in vivo studies conducted in the second half of the last century made it clear that steroid sex hormones regulate cell proliferation and play a major role in promoting BC. 2,3 Several mechanistic hypotheses for the development of BC have been proposed, 2,4 but until recently, hormone measurements by epidemiological studies have failed to corroborate any of them. Over the last decade, however, several prospective cohort studies in postmenopausal women have shown that BC development is preceded by alterations in levels of circulating sex hormones. 5 High serum levels of free and total estradiol, total testosterone and other estrogens and androgens, as well as low serum levels of sex hormone-binding globulin (SHBG), have been found to be implicated in the risk of BC. 5 Our own study also indicated that high serum levels of free testosterone are associated with the risk of BC. 6 These prospective investigations were carried out with the help of thousands of healthy women who provided blood samples for storage and future nested-in-the-cohort case-control analyses. Compared to case control studies in clinical settings, the strengths of prospective studies are that control subjects belong to the same cohort that generates the incident disease cases and that blood is collected before the diagnosis of cancer thereby excluding abnormal values that may be due to overt illness. Hormone measurements in premenopausal women are difficult to interpret because serum levels change with the menstrual cycle and because cycle length varies inter-and intra-individually. Only a few prospective investigations have addressed the role of sex hormone levels in BC before the menopause; 7-10 all considered small numbers of case women and did not produce clear results. The endocrine basis of BC in premenopause is therefore the subject of several disparate hypotheses. These include the hypothesis of Grattarola, advanced in the 1960s, 11-12 that hyperandrogenism with luteal inadequacy plays a role in the induction of BC, and of Henderson et al. The present prospective study was designed to investigate whether luteal inadequacy and hyperandrogenism increase the risk of BC in premenopausal women. We collected blood samples from premenopausal women participating in the study on Hormones and Diet in the Etiology of Breast Tumors (ORDET). 6,14 Samples were taken between the 20th and 24th day of the cycle (theoretically during the mid luteal phase). The first day of menstrual bleeding subsequent to sampling was also recorded to provide an additional data point for correctly locating the sampling day within the cycle. In these women, we analyzed the relationship between BC and serum levels of the androgens dehydroepiandrosterone sulfate (DHEAS), total testosterone, free testosterone, androstenedione and androstanediol-glucoronide (Adiol-G), and also progesterone, 17-OH-progesterone, SHBG, follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Estradiol was not considered in the present analysis because of its extraordinary intra-individual variation in premenopausal women

Group b streptococcus late-onset disease: 2003-2010

BACKGROUND: There is insufficient population-based data on group B streptococcus (GBS) late-onset disease (LOD). Risk factors and routes of GBS transmission are poorly understood. METHODS: A prospective, cohort study was conducted to collect incidence data on LOD and evaluate GBS infections over an 8-year period (2003-2010). Starting from January 2007, maternal rectovaginal and breast milk cultures were routinely collected on confirmation of the LOD diagnosis to assess maternal GBS culture status. RESULTS: The incidence rate of LOD was 0.32 per 1000 live births (1.4 and 0.24 per 1000 live births for preterm and term newborns, respectively). The registered cases of LOD (n = 100) were classified as sepsis (n = 57), meningitis (n = 36), or focal infection (n = 7). Thirty neonates were preterm (2 had recurrent infection); 68 were term. Four infants died (3 early preterm, 1 term). At the time the LOD diagnosis was confirmed, 3 (6%) of 53 mothers had GBS mastitis, and 30 (64%) of 47 carried GBS at the rectovaginal site. Early (7-30 days) LOD presentation was associated with neonatal brain lesions or death (odds ratio: 0.96 [95% confidence interval: 0.93-0.99]). Intrapartum antibiotic exposure was significantly associated with mild (12 of 22) rather than severe (11 of 45; P = .03) LOD. CONCLUSIONS: Preterm neonates had the highest rates of LOD and mortality. Most mothers carried GBS at the time of the LOD diagnosis, whereas 6% had mastitis. Intrapartum antibiotics were associated both with delayed presentation of symptoms and milder LOD. Pediatrics 2013;131:e361-e368Early neonatal mortality has remained high and unchanged for many years in Tanzania, a resource-limited country. Helping Babies Breathe (HBB), a novel educational program using basic interventions to enhance delivery room stabilization/resuscitation, has been developed to reduce the number of these deaths. METHODS: Master trainers from the 3 major referral hospitals, 4 associated regional hospitals, and 1 district hospital were trained in the HBB program to serve as trainers for national dissemination. A before (n = 8124) and after (n = 78 500) design was used for implementation. The primary outcomes were a reduction in early neonatal deaths within 24 hours and rates of fresh stillbirths (FSB). RESULTS: Implementation was associated with a significant reduction in neonatal deaths (relative risk [RR] with training 0.53; 95% confidence interval [CI] 0.43-0.65; P ≤.0001) and rates of FSB (RR with training 0.76; 95% CI 0.64-0.90; P = .001). The use of stimulation increased from 47% to 88% (RR 1.87; 95% CI 1.82-1.90; P ≤.0001) and suctioning from 15% to 22% (RR 1.40; 95% CI 1.33-1.46; P ≤.0001) whereas face mask ventilation decreased from 8.2% to 5.2% (RR 0.65; 95% CI 0.60- 0.72; P ≤ .0001).

Sleep behavior and daily activity levels in people with metabolic syndrome: effect of 1 year of metformin treatment

Impaired sleep and low daily activity levels increase the risk of developing metabolic syndrome (MS). Metformin (MET), an insulin sensitizer drug, is effective in regressing MS and has been recently studied as an adjuvant agent for managing sleep disorders. The present study aimed to assess whether 1,700 mg/day of MET treatment modifies sleep and daily activity levels in people with MS evaluated by Rest-Activity circadian Rhythm (RAR), which is the expression of 24 h of spontaneous activity parameters. A total of 133 subjects with MS, randomized into the MET (n = 65) or placebo (PLA, n = 68) group, underwent a clinical/anthropometric examination and carried out a continuous 7-day actigraphic monitoring to investigate sleep and RAR parameters at baseline and after 1 year of intervention. After 1 year of intervention, 105 subjects were analyzed. The MET group showed greater anthropometric and metabolic improvements compared with placebo, with a significant reduction in weight (p = 0.01), body mass index (p = 0.01), waist circumference (p = 0.03), and glucose (p < 0.001). With regard to sleep parameters, the MET group showed a significant increase in actual sleep time (p = 0.01) and sleep efficiency (p = 0.04) compared with placebo. There were no significant changes reported in the RAR parameters. Our study suggests that MET might be used as an adjuvant treatment for sleep disorders in people with MS

The impact of chest CT body composition parameters on clinical outcomes in COVID-19 patients

We assessed the impact of chest CT body composition parameters on outcomes and disease severity at hospital presentation of COVID-19 patients, focusing also on the possible mediation of body composition in the relationship between age and death in these patients. Chest CT scans performed at hospital presentation by consecutive COVID-19 patients (02/27/2020-03/13/2020) were retrospectively reviewed to obtain pectoralis muscle density and total, visceral, and intermuscular adipose tissue areas (TAT, VAT, IMAT) at the level of T7-T8 vertebrae. Primary outcomes were: hospitalization, mechanical ventilation (MV) and/or death, death alone. Secondary outcomes were: C-reactive protein (CRP), oxygen saturation (SO2), CT disease extension at hospital presentation. The mediation of body composition in the effect of age on death was explored. Of the 318 patients included in the study (median age 65.7 years, females 37.7%), 205 (64.5%) were hospitalized, 68 (21.4%) needed MV, and 58 (18.2%) died. Increased muscle density was a protective factor while increased TAT, VAT, and IMAT were risk factors for hospitalization and MV/death. All these parameters except TAT had borderline effects on death alone. All parameters were associated with SO2 and extension of lung parenchymal involvement at CT; VAT was associated with CRP. Approximately 3% of the effect of age on death was mediated by decreased muscle density. In conclusion, low muscle quality and ectopic fat accumulation were associated with COVID-19 outcomes, VAT was associated with baseline inflammation. Low muscle quality partly mediated the effect of age on mortality.We assessed the impact of chest CT body composition parameters on outcomes and disease severity at hospital presentation of COVID-19 patients, focusing also on the possible mediation of body composition in the relationship between age and death in these patients.
