Biofortification: Effect of Iodine Fortified Food in the Healthy Population, Double-Arm Nutritional Study
It is estimated that one-third of the world’s population lives in areas where iodine (I) is scarce and its deficiency is responsible for many related disorders, such as goiter, reproductive failure, hearing loss, growth impairment, congenital I deficiency syndrome, and numerous kinds of brain injury. Mineral deficiencies can be overcome via dietary diversification and mineral supplementation. An alternative or even complementary way is represented by the intake of biofortified foods, which can tackle this lack of micronutrients. In this short-term double-arm nutritional intervention study, a cohort of ten people was supplemented with curly endive leaf biofortified with I and ten people with curly endive without biofortification (Intervention Study on Iodine Biofortification Vegetables (Nutri-I-Food – Full-Text View - ClinicalTrials.gov). The effects on whole-body homeostasis and specifically on I, glucose, lipid, and hepatic, iron metabolism was investigated. Blood samples were obtained at baseline and after 12 days of supplementation with curly endive and compared with controls. Hematochemical and urinary parameters were analyzed at baseline and after 12 days. The results showed that short-term I curly endive intervention did not affect the whole body homeostasis in healthy people and revealed an increase in I concentration in urine samples and an increase in vitamin D, calcium, and potassium concentration in blood samples only in the biofortified cohort respect to controls. This study suggests that short-term consumption of I curly endive crops is safe and could positively impact body health
Microclimatic Alteration after Logging Affects the Growth of the Endangered Lichen Lobaria pulmonaria
Microclimatic conditions are important in determining lichen distribution at small scale, and may determine whether the species persist when the surrounding environmental conditions have drastically changed. This is the case with forest management, since a sudden variation of microclimatic conditions (increase of solar radiation, temperature, wind and a reduction of humidity) may occur after logging. In this study, the combined effect of forest logging and microclimatic conditions on the growth probabilities and growth rates of the model species Lobaria pulmonaria was assessed in mixed oak stands. To this purpose, 800 fragments of L. pulmonaria (<1 cm) were transplanted in logged and unlogged stands for two years. Young and adult fragments were positioned on Turkey oak boles according to distance from the ground (100 and 50 cm) and aspect (north and south). The results, evaluated by generalized linear mixed models on a yearly basis, highlighted differences in growth—particularly on isolated trees in the logged stand. South-exposed samples in the logged stand showed a low probability of growth, while samples transplanted north in the unlogged stand showed higher growth probabilities. However, the highest annual growth coefficients corresponded to south-exposed samples 50 cm from the ground in the unlogged stand. In general, higher growth rates were observed in young thallus fragments when compared with adult ones. Beyond confirming the importance of microclimate for lichen ecology, these results could be implemented in conservation actions to preserve L. pulmonaria populations in logged forests
Outcome following a short period of adalimumab dose escalation as rescue therapy in psoriatic patients
Background: Advances in biologic treatments have led to a new therapeutic frontier for moderate-to-severe psoriasis. Nevertheless, the efficacy of anti-TNFα decreases with time, requiring adjustments to maintain valuable Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) responses. Objectives: To evaluate the efficacy and safety of adalimumab dose escalation (40 mg, subcutaneous, once a week for 24 weeks) in psoriatic adult patients with secondary loss of response (PASI ≥50 to ≤75 or PASI≥75 and DLQI ≥5). Materials and Methods: A multicentre, observational study involving different Italian third-level referral centres for psoriasis enrolled a total of 64 adult patients with moderate-to-severe psoriasis who were treated with adalimumab and experienced a secondary loss of response. Primary end-points were PASI< 75 or PASI ≥50 to ≤ 75 with DLQI ≤ 5, and the secondary end-point was the ability to maintain a therapeutic response, resuming adalimumab every other week. Results: At Week 16 and Week 24, 29/64 (45.3%) and 35/64 (54.6%) responded based on PASI, and mean DLQI was 4.9 and 4.09, respectively. At Week 36 and Week 48, 45.3% and 28.1% patients achieved the second end-point, respectively. No adverse events were recorded except for one patient with recurrent tonsillitis. Conclusion: Adalimumab escalation could be considered in cases with loss of response before switching to alternative biologic therapy

Preventive Impact of Long-Term Ingestion of Chestnut Honey on Glucose Disorders and Neurodegeneration in Obese Mice
The purpose of the present study was to evaluate the impact of long-term honey ingestion
on metabolic disorders and neurodegeneration in mice fed a high-fat diet (HFD). Three groups of mice
were fed with a standard diet (STD), HFD or HFD supplemented with honey (HFD-H) for 16 weeks.
Biochemical, histological, Western blotting, RT-PCR and Profiler PCR array were performed to
assess metabolic parameters, peripheral and central insulin resistance and neurodegeneration. Daily
honey intake prevented the HFD-induced glucose dysmetabolism. In fact, it reduced plasma fasting
glucose, insulin and leptin concentrations and increased adiponectin levels. It improved glucose
tolerance, insulin sensitivity and HOMA index without affecting plasma lipid concentration. HFD
mice showed a significantly higher number of apoptotic nuclei in the superficial and deep cerebral
cortex, upregulation of Fas-L, Bim and P27 (neuronal pro-apoptotic markers) and downregulation
of Bcl-2 and BDNF (anti-apoptotic factors) in comparison with STD- and HFD-H mice, providing
evidence for honey neuroprotective effects. PCR-array analysis showed that long-term honey intake
increased the expression of genes involved in insulin sensitivity and decreased genes involved
in neuroinflammation or lipogenesis, suggesting improvement of central insulin resistance. The
expressions of p-AKT and p-GSK3 in HFD-H mice, which were decreased and increased, respectively,
in HFD mouse brain, index of central insulin resistance, were similar to STD animals supporting the
ability of regular honey intake to protect brain neurons from insulin resistance. In conclusion, the
present results provide evidence for the beneficial preventative impact of regular honey ingestion on
neuronal damage caused by HFD
Paralytic ileus, a new rare toxicity of capecitabine: Two case reports
Paralytic ileus (or adynamic ileus) refers to a lack of passage of intestinal contents due to disturbances of normal intestinal motility, in absense of mechanical obstruction. The most common causes are intra-abdominal surgery, severe metabolic problems, drugs. We present two clinical cases related to patients with breast cancer and admitted with paralytic ileus following treatment with capacitabine in local Lanciano Hospital. Naranjo, Jones algoritms suggest a direct causal relationship. Our two cases, to our knowledge, represent the first published report of this particular intestinal toxicity of capecitabine. Pathophisiological explanation is difficult because no data are known about fluoropyrimidines effects on enteric motor functions (motor system, neural influences, hormonal factors): Tegafur (UFT) also, another oral fluoropyrimidine, induces paralytic ileus. We hypothesize that some 5-flourouracil metabolites (5-fluorocitrate; fluoro-beta-alanine), seldom responsible for central and peripherical neurotoxicity from fluoropyrimidines, can sometimes cause a neuropathy, and so a paralytic ileus. Paralytic ileus is probably a rare complication of capecitabine, but the oncologist should take it into careful consideration, because of his possible seriousness and because a suitable management of early signs of abdominal distension (with nasogastric suction and/or rectal tube, i.v. infusion of fluids and electrolytes, etc.) can avoid a unnecessary operative treatment
Metabolic abnormalities associated with initiation of systemic treatment for psoriasis: evidence from the Italian Psocare Registry.
Objective To evaluate variations in laboratory parameters and diagnoses of selected clinical conditions up to16 weeks after starting a new systemic psoriasis treatment for Psocare Registry enrollees.Design Prospective cohort study.Setting Italian public referral centres for psoriasis treatment.Patients First-time recipients (n = 10,539) of continuous systemic psoriasis treatment for at least 16 weeks.Main outcome measure Mean variations in (weeks 8 and 16) and proportions of patients reaching a clinicallymeaningful increase in serum levels (week 16) of total and low-density lipoprotein cholesterol, triglycerides, aspartateamino transferase, alanine amino transferase and creatinine, as well as week-16 cumulative incidences of newdiagnoses of diabetes mellitus and arterial hypertension.Results Mean cholesterol and triglyceride levels significantly increased in patients treated with acitretin orcyclosporine. Mean triglyceride levels also increased in efalizumab- and etanercept-treated patients. Meantransaminase values increased in methotrexate-treated patients, and mean aspartate amino transferase levelsincreased in infliximab-treated patients. The average serum creatinine value increased in cyclosporine-treatedpatients. Acitretin and cyclosporine were associated with risk of hypercholesterolaemia (odds ratios 1.51 and 1.34)and acitretin with risk of hypertriglyceridaemia (odds ratio 1.43). Methotrexate and infliximab were associated withrisk of more than doubling the upper normal aspartate amino transferase (odds ratios 2.06 and 1.87) and alanineamino transferase (odds ratios 2.38 and 1.74) values. The relative risk of developing arterial hypertension anddiabetes was increased for patients receiving cyclosporine (odds ratios 3.31 and 2.88).Conclusion Systemic treatments for psoriasis resulted in heterogeneous effects on the parameters analysed.Received: 1 September 2011; Accepted: 12 January 201
