A simple prognostic index in acute heart failure
Background Rapid effective triage is integral to emergency care in patients hospitalized for heart failure, to guide the type and intensity of therapy. Several indexes and scores have been proposed to predict outcome; most of the them are complex and unfit to use at the bedside. Methods We propose a new prognostic index for in hospital mortality in acute heart failure. The index was built according to the formula; 220 – age – heart rate + systolic blood pressure – ( creatinine X 10). The index was tested in 1628 patients admitted for acute heart failure and enrolled, from November 2007 to December 2009, in the Italian Registry on Heart Failure Outcome ( IN-HF); a prospective, multicentre, observational study. Results The prognostic index was an independent predictor for in hospital mortality risk ( c statistic= 0.74) (p<0.0001), together with left ventricular ejection fraction (p= 0.001), Glycemia ( p= 0.019) and hemoglobin concentration (p = 0.002). Conclusion A simple prognostic index based on variables easily assessed can be useful to predict mortality in acute heart failure at the first arrival in hospital
Discriminating Interactions Between Chiral Molecules In the Liquid-phase - Effect On Volumetric Properties
Volume changes on mixing for binary mixtures of optically active liquid compounds have been determined
at 25 "C by using a vibrating tube densimeter. Six enantiomeric and six nonenantiomeric pairs of chiral molecules
have been considered. In all the cases chiral discrimination appeared to produce small but significant effects
(0.0024.016 cm3 mol-'). The excess molar volumes, p, of the (+) and (-) isomers of limonene, carvone,
2-methyl-1-butanol, and a-methylbenzylamine showed negative values, while VE of the enantiomers of a-pinene
and 2-odanol gave positive results. Partial molar volumes, Po,fo r the investigated chiral solutes in chiral solvents
have been obtained from p data. The effecta of chiral discrimination of Po have been compared with the
prediction of a simple statistical approach in which discrimination arises from space-filling differences in contacts
between hard surfaces

Lung structure and function similarities between primary ciliary dyskinesia and mild cystic fibrosis: a pilot study
BACKGROUND:
Primary ciliary dyskinesia (PCD) and cystic fibrosis (CF) are increasingly compared. There are no chest magnetic resonance imaging (MRI) comparative studies of PCD and CF. We assessed clinical, functional, microbiological and MRI findings in PCD and mild CF patients in order to evaluate different expression of lung disease.
METHODS:
Twenty PCD (15.1 years) and 20 CF subjects with mild respiratory impairment (16 years, 70% with pancreatic insufficiency) underwent MRI, spirometry, and sputum cultures when clinically stable. MRI was scored using the modified Helbich system.
RESULTS:
PCD was diagnosed later than CF (9.9 versus 0.6 years, p = 0.03), despite earlier symptoms (0.1 versus 0.6 years, p = 0.02). In the year preceding the study, patients from both groups underwent two systemic antibiotic courses (p = 0.48). MRI total scores were 11.6 ± 0.7 and 9.1 ± 1 in PCD and CF, respectively. FEV1 and FVC Z-scores were -1.75 (range, -4.6-0.7) and -0.6 (-3.9-1.8) in PCD, and -0.9 (range, -5.4-2.3) and -0.3 (-3.4-2.5) in CF, respectively. No difference was found between lung function or structure, despite a higher MRI subscore of collapse/consolidation in PCD versus CF (1.6 ± 0.1 and 0.6 ± 0.2, p < 0.001). These findings were confirmed after data-control for diagnostic delay. Pseudomonas aeruginosa and Staphylococcus aureus were more frequent in CF than in PCD (p = 0.05 and p = 0.003, respectively).
CONCLUSIONS:
MRI is a valuable radiation-free tool for comparative PCD and CF lung disease assessment. Patients with PCD may exhibit similar MRI and lung function changes as CF subjects with mild pulmonary disease. Delay in PCD diagnosis is unlikely the only determinant of similarities
The Social Brain and Emotional Contagion: COVID-19 Effects
Background and objectives: Coronavirus disease 2019 (COVID-19) is a highly contagious
infectious disease, responsible for a global pandemic that began in January 2020. Human/COVID-19
interactions cause dierent outcomes ranging from minor health consequences to death. Since social
interaction is the default mode by which individuals communicate with their surroundings,
dierent modes of contagion can play a role in determining the long-term consequences for mental
health and emotional well-being. We examined some basic aspects of human social interaction,
emphasizing some particular features of the emotional contagion. Moreover, we analyzed the main
report that described brain damage related to the COVID-19 infection. Indeed, the goal of this
review is to suggest a possible explanation for the relationships among emotionally impaired people,
brain damage, and COVID-19 infection. Results: COVID-19 can cause several significant neurological
disorders and the pandemic has been linked to a rise in people reporting mental health problems,
such as depression and anxiety. Neurocognitive symptoms associated with COVID-19 include
delirium, both acute and chronic attention and memory impairment related to hippocampal and
cortical damage, as well as learning deficits in both adults and children. Conclusions: Although our
knowledge on the biology and long-term clinical outcomes of the COVID-19 infection is largely
limited, approaching the pandemic based on lessons learnt from previous outbreaks of infectious
diseases and the biology of other coronaviruses will provide a suitable pathway for developing
public mental health strategies, which could be positively translated into therapeutic approaches,
attempting to improve stress coping responses, thus contributing to alleviate the burden driven by
the pandemic
Resistance to Systemic Agents in Renal Cell Carcinoma Predict and Overcome Genomic Strategies Adopted by Tumor
The development of new systemic agents has led us into a “golden era” of management
of metastatic renal cell carcinoma (RCC). Certainly, the approval of immune-checkpoint inhibitors
and the combination of these with targeted compounds has irreversibly changed clinical scenarios.
A deeper knowledge of the molecular mechanisms that correlate with tumor development and
progression has made this revolution possible. In this amazing era, novel challenges are awaiting us
in the clinical management of metastatic RCC. Of these, the development of reliable criteria which are
able to predict tumor response to treatment or primary and acquired resistance to systemic treatments
still remain an unmet clinical need. Thanks to the availability of data provided by studies evaluating
genomic assessments of the disease, this goal may no longer be out of reach. In this review, we
summarize current knowledge about genomic alterations related to primary and secondary resistance
to target therapy and immune-checkpoint inhibitors in RC
Guinea worm wrap-up
Sudan has reported 21,433 cases of dracunculiasis in January-July 2002, which is 73% of the global total of cases reported for that period. Whereas 36% of 8,058 endemic villages reported in January-July 2001, 62% of 6,224 endemic villages reported during the same period of 2002. The latest update on the status of the program was discussed during the annual Program Review of the Guinea Worm Eradication Programs of Sudan, Ethiopia and Uganda, which was held in Nairobi, Kenya on September 30 \ue2\u20ac\u201c October 2. The percentage of known endemic villages with nylon filters in every household increased from 29% to 58% between 2001 and 2002, and over 7 million pipe filters were distributed in 2001. Health education talks by village volunteers have increased from 50% to 83% of endemic villages, and are increasingly supplemented by radio broadcasts in local languages. Abate usage is still limited in all but the northern states of the country
Adjuvant therapy in renal cell carcinoma: is it the right strategy to inhibit VEGF?
Despite several clinical trials have assessed different agents in the adjuvant setting, renal cell carcinoma (RCC) still remains a disease orphan of an effective adjuvant treatment. In fact, systemic therapies targeting angiogenesis that have been observed to be effective in metastatic setting failed to show an improvement in terms of clinical outcomes when used ad adjuvant treatments. In this study, we performed a meta-analysis of 5 randomized clinical trials to assess the impact of tyrosine kinase inhibitors (TKIs) targeting angiogenesis after surgery: ASSURE, S-TRAC, PROTECT, ATLAS, SORCE. Among the 6,531 patients assessed, we confirmed the lack of efficacy of adjuvant treatments in terms of disease-free survival (DFS) (pooled-HR 0.93, 95% CI, 0.84–1.02, P=0.16) and overall survival (OS) (pooled-HR 0.98, 95% CI, 0.88–1.09, P=0.54). To the best of our knowledge, we still ignore why some treatments active in the metastatic setting do not show similar efficacy as adjuvant treatment. Exploring possible reasons of this apparently conflicting results is important as it may offer new insights that should be evaluated in next generation adjuvant trials. Immune checkpoint inhibitors (ICIs) have reported significant results—as monotherapy or in combinations with other anticancer agents—in metastatic setting, and the results of trials evaluating these agents in the adjuvant setting are awaited
Clinical and surgical data of affected members of a classic CFEOM 1 family
BACKGROUND: Congenital fibiosis of the extraocular muscles (CFEOM1) refers to a group of congenital eye movement disorders that are characterized by non-progressive restrictive ophthalmoplegia. We present clinical and surgical data on affected members of a classic CFEOM1 family. METHODS: Ten members of a fifteen-member, three-generation Italian family affected by classic CFEOM participated in this study. Each affected family member underwent ophthalmologic (corrected visual acuity, pupillary function, anterior segment and fundus examination), orthoptic (cover test, cover-uncover test, prism alternate cover test), and preoperative examinations. Eight of the ten affected members had surgery and underwent postoperative examinations. Surgical procedures are listed. RESULTS: All affected members were born with varying degrees of bilateral ptosis and ophthalmoplegia with both eyes fixed in a hypotropic position (classic CFEOM). The affected members clinical data prior to surgery, surgery procedures and postoperative outcomes are presented. On 14 operated eyes to correct ptosis there was an improvement in 12 eyes. In addition, the head position improved in all patients. CONCLUSIONS: Surgery is effective at improving ptosis in the majority of patients with classic CFEOM. However, the surgical approach should be individualized to each patient, as inherited CFEOM exhibits variable expressivity and the clinical features may differ markedly between affected individuals, even within the same family
Rationale and design of an independent randomised controlled trial evaluating the effectiveness of aripiprazole or haloperidol in combination with clozapine for treatment-resistant schizophrenia
<p>Abstract</p> <p>Background</p> <p>One third to two thirds of people with schizophrenia have persistent psychotic symptoms despite clozapine treatment. Under real-world circumstances, the need to provide effective therapeutic interventions to patients who do not have an optimal response to clozapine has been cited as the most common reason for simultaneously prescribing a second antipsychotic drug in combination treatment strategies. In a clinical area where the pressing need of providing therapeutic answers has progressively increased the occurrence of antipsychotic polypharmacy, despite the lack of robust evidence of its efficacy, we sought to implement a pre-planned protocol where two alternative therapeutic answers are systematically provided and evaluated within the context of a pragmatic, multicentre, independent randomised study.</p> <p>Methods/Design</p> <p>The principal clinical question to be answered by the present project is the relative efficacy and tolerability of combination treatment with clozapine plus aripiprazole compared with combination treatment with clozapine plus haloperidol in patients with an incomplete response to treatment with clozapine over an appropriate period of time. This project is a prospective, multicentre, randomized, parallel-group, superiority trial that follow patients over a period of 12 months. Withdrawal from allocated treatment within 3 months is the primary outcome.</p> <p>Discussion</p> <p>The implementation of the protocol presented here shows that it is possible to create a network of community psychiatric services that accept the idea of using their everyday clinical practice to produce randomised knowledge. The employed pragmatic attitude allowed to randomly allocate more than 100 individuals, which means that this study is the largest antipsychotic combination trial conducted so far in Western countries. We expect that the current project, by generating evidence on whether it is clinically useful to combine clozapine with aripiprazole rather than with haloperidol, provides physicians with a solid evidence base to be directly applied in the routine care of patients with schizophrenia.</p> <p>Trial Registration</p> <p><b>Clincaltrials.gov Identifier</b>: NCT00395915</p
