Food is Never Enough: Nature and Nurture's Influence on Children's Food Dose Evaluation

This study investigated whether if socioeconomic factors and\or food palatability influence food amount evaluation among children. Ninety-four children, 10–15 years old, living in Mali in Africa, and 124 living in northern Italy were asked to evaluate an amount of palatable and non palatable candies. The evaluations were compared both to the real number of candies and to that given by the other group. Both Italian and Malian children underestimated the edible candies, interestingly however Malian children did not underestimate altered candies. The data suggest that food dose underestimation is a transcultural characteristic. Evaluation of palatable food is not influenced by socio cultural factors. Underestimation could be a biological protective factor against food shortage; in case of food abundance it could play a role in onset and maintenance of obesity.     

Pharmacokinetic drug evaluation of dolutegravir plus rilpivirine for the treatment of HIV

Introduction: The search for simple, potent, metabolic-friendly and nucleoside/nucleotide sparing antiretroviral regimens has led clinical investigators to move steps towards dual therapies. Among these the association of rilpivirine and dolutegravir is emerging as a twin randomized clinical trial (SWORD1&2) and at least three observational cohort describe it as a safe and highly effective regimen for switch from other therapies

Areas covered: We review the evidence supporting the use of dolutegravir plus rilpivirine for the treatment of HIV in virologically suppressed patients taking other antiretroviral regimens. The reasons for the switch in clinical practice may range from simplification to tolerability/toxicity issues, to the prevention of future metabolic damage, to predicted drug-drug interactions when treatment of HCV co-infection is planned. Articles searchable on MEDLINE/PubMed and from the main international congresses in the field of HIV therapy were reviewed to provide context for use of dolutegravir plus rilpivirine

Expert opinion: This treatment is highly effective in maintaining HIV-1 RNA <50 copies/mL. Although the studies up to date requested patient to switch to drugs they had no experience of, a predictable ‘radical change’ effect did not impact negatively on the results. Further data from these studies may help elucidate the possible advantage in terms of safety and metabolic effect in the next few months.

PredyCLU: A prediction system for chronic leg ulcers based on fuzzy logic; part II—Exploring the arterial side

Peripheral arterial disease (PAD) and its most severe form, critical limb ischaemia (CLI), are very common clinical conditions related to atherosclerosis and represent the major causes of morbidity, mortality, disability, and reduced quality of life (QoL), especially for the onset of ischaemic chronic leg ulcers (ICLUs) and the subsequent need of amputation in affected patients. Early identification of patients at risk of developing ICLUs may represent the best form of prevention and appropriate management. In this study, we used a Prediction System for Chronic Leg Ulcers (PredyCLU) based on fuzzy logic applied to patients with PAD. The patient population consisted of 80 patients with PAD, of which 40 patients (30 males [75%] and 10 females [25%]; mean age 66.18 years; median age 67.50 years) had ICLUs and represented the case group. Forty patients (100%) (27 males [67.50%] and 13 females [32.50%]; mean age 66.43 years; median age 66.50 years) did not have ICLUs and represented the control group. In patients of the case group, the higher was the risk calculated with the PredyCLU the more severe were the clinical manifestations recorded. In this study, the PredyCLU algorithm was retrospectively applied on a multicentre population of 80 patients with PAD. The PredyCLU algorithm provided a reliable risk score for the risk of ICLUs in patients with PAD.     

Radiation‐induced nausea and vomiting in head and neck cancer: Is it something worth considering in the intensity modulated radiotherapy era? “A narrative review”

Radiation therapy is one of the cornerstones in the treatment of head and neck squamous cell carcinomas (HNSCC), alone or in combination with chemotherapy or surgery. Technological advances which occurred over the last few decades have increased the efficacy of radiotherapy (RT), particularly, intensity‐modulated RT (IMRT). IMRT can deliver treatments on complex tumoral targets with dose escalation while sparing organs at risk; anyway IMRT deposits dose in unpredictable patterns outside of the target volume with the purpose of improving conformality. Radiation‐induced nausea and vomiting (RINV) is a frequent albeit neglected side effect of RT that can lead to delays in treatment with serious consequences on cure rates. According to several guidelines (MASCC 2016, NCCN 2018), RT for HNSCC has traditionally been regarded as a low emetic risk treatment. Nevertheless, several works suggest that IMRT could increase RINV. Further studies are needed to define the exact incidence and the detailed pathophysiology of RINV in patients with HNSCC treated with state of art IMRT techniques, with and without concurrent chemotherapy.

A phase III randomized trial of high‐dose CEOP + filgrastim versus standard‐dose CEOP in patients with non‐Hodgkin lymphoma: 10‐year follow‐up data: Australasian Leukaemia and Lymphoma Group (ALLG) NHL07 trial

Increasing dose intensity (DI) of chemotherapy for patients with aggressive non‐Hodgkin lymphoma (NHL) may improve outcomes at the cost of increased toxicity. This issue was addressed in a randomized trial aiming to double the DI of myelosuppressive drugs. Between 1994 and 1999, 250 patients with previously untreated aggressive NHL were randomized to treatment with six cycles of 3‐weekly standard (s) or intensive (i) chemotherapy: s‐CEOP–cyclophosphamide 750, epirubicin 75, vincristine 1.4 mg/m² all on day 1, and prednisolone 100 mg days 1–5; i‐CEOP–cyclophosphamide 1,500, epirubicin 150, vincristine 1.4 mg/m² all on day 1, and prednisolone 100 mg days 1–5. Primary endpoint was 5‐year overall survival (OS). Relative to s‐CEOP patients, i‐CEOP patients achieved a 78% increase in the DI of cyclophosphamide and epirubicin. Despite this, there was no significant difference in any outcome: 5‐year OS (56.7% i‐CEOP; 55.1% s‐CEOP; P = 0.80), 5‐year progression free survival (PFS; 41% i‐CEOP; 43% s‐CEOP; P = 0.73), 5‐year time to progression (TTP; 44% i‐CEOP; 47% s‐CEOP; P = 0.72), or complete remission (CR) + unconfirmed CR (CRu) rates (53% i‐CEOP; 59% s‐CEOP; P = 0.64). Long‐term follow up at 10 years also showed no significant differences in OS, PFS, or TTP. The i‐CEOP arm had higher rates of febrile neutropenia (70 vs. 26%), hospitalisations, blood product utilisation, haematological and gastrointestinal toxicities, and lower quality of life scores during treatment, although without significant differences 6‐month later. In the treatment of aggressive NHL in the prerituximab era, increasing DI did not result in improved outcomes, while at the same time lead to increased toxicity. Am. J.

Alterations in pain processing circuitries in episodic migraine

BackgroundThe precise underlying mechanisms of migraine remain unknown. Although we have previously shown acute orofacial pain evoked changes within the brainstem of individuals with migraine, we do not know if these brainstem alterations are driven by changes in higher cortical regions. The aim of this investigation is to extend our previous investigation to determine if higher brain centers display altered activation patterns and connectivity in migraineurs during acute orofacial noxious stimuli.MethodsFunctional magnetic resonance imaging was performed in 29 healthy controls and 25 migraineurs during the interictal and immediately (within 24-h) prior to migraine phases. We assessed activation of higher cortical areas during noxious orofacial heat stimulation using a thermode device and assessed whole scan and pain-related changes in connectivity.ResultsDespite similar overall pain intensity ratings between all three groups, migraineurs in the group immediately prior to migraine displayed greater activation of the ipsilateral nucleus accumbens, the contralateral ventrolateral prefrontal cortex and two clusters in the dorsolateral prefrontal cortex (dlPFC). Reduced whole scan dlPFC [Z + 44] connectivity with cortical/subcortical and brainstem regions involved in pain modulation such as the putamen and primary motor cortex was demonstrated in migraineurs. Pain-related changes in connectivity of the dlPFC and the hypothalamus immediately prior to migraine was also found to be reduced with brainstem pain modulatory areas such as the rostral ventromedial medulla and dorsolateral pons.ConclusionsThese data reveal that the modulation of brainstem pain modulatory areas by higher cortical regions may be aberrant during pain and these alterations in this descending pain modulatory pathway manifests exclusively prior to the development of a migraine attack.
