[THE TEN MOST CITED ARTICLES OF THE JOURNAL "NUTRICION HOSPITALARIA"]

After 36 years of continued publication of the journal Nutrición Hospitalaria, a list with the ten most cited articles published in it is elaborated. The top ten most cited articles in the world literature and stratification according to language, English or Spanish, subject, or period of time published are also analyzed. Nutr Hosp is the most important Ibero latin American nutrition journal. Nutr Hosp published 369 items in 2014 gaining the fourth position among all the world's journals devoted to nutrition. Article publication in English, or simultaneously in Spanish and English and Open Access policy probably benefit the number of citations.

[SOME CONSIDERATIONS ABOUT THE INTRINSIC VALUE OF THE IMPACT FACTOR OF SCIENTIFIC JOURNALS]

The reason of higher number of citations of some articles is discussed. Some considerations about the journals' impact factor, its merits and its pitfalls are also made. Scientific journals' impact factor, popularized by the Institute for Scientific Information, has become an objective parameter for authors' evaluation and also for institutions and other related circumstances. There is no reason for the impact factor's gap between some English journals and those written in other languages. English journals probably benefit of the "Mathew's effect", according to which eminent scientists are more rewarded by similar contributions than others less known. It is paradoxical that most of the major achievements of our age do not appear among the 100 most cited articles. There is no homogeneity among all the articles appearing in each scientific journal: half of the articles are cited ten times more than the other half. However, those articles cited 0 times are credited like the better ones. Each article should be evaluated by its own citations, which would be its impact factor; the authors should be evaluated by their H index.

[FIXING DEVICE FOR CLOSING AND COUPLING AN INTRAVENOUS CATHETER]

INTRODUCTION

skin fixing devices in peripheral, central or arterial catheters have several important drawbacks: site infection, stacking of material in the anatomical area which is very annoying for the patient and medical staff risk when fixating stitches are used.

OBJECTIVE

to develop a fixing device that simplifies presently used systems, favoring asepsis and motility.

METHODS

the device herein described is composed by a mechanical fixation, a closing system and coupling for intravenous catheters. The system has a thin circular piece with at least two holes for subcutaneous fixation, one or several conducts for lumina and a hollow cylindrical part in one side, screwed exteriorly and flat inside, with an oriented protuberance. A watertight plug with one or several thin tubes that adapt to the lumina, a positional slot, a handle and a solid screwed tap for perfect closure are available for at home use. An intermediate plug with one or several lumina and a screwed hollow plug are provided for in hospital use.

RESULTS

the above described device is intended to be used in two settings: in hospital and at home. It is supposed to reduce the risk of infection and stacking of the anatomical site where cutaneo us puncture with fixation of peripheral, central or arterial catheters is performed.

Malnutrition, pharmaconutrition and other considerations in AL amyloidosis, a rare disease with masquerading symptoms and usually delayed diagnosis

Amyloid Light-chain (AL) amyloidosis is a very rare disease. Nutritional and pharmaconutrional aspects are described. Nutrition repletion of malnourished AL patients is an essential strategy for improving treatment efficacy and clinical outcomes. Early diagnosis of AL amiloidosis is difficult to establish due to the fact that signs and symptoms appearing mimic other processes that delay the final correct histological diagnosis. Untreated patients with this disease have a dismal outcome, with a median survival of 10-14 months from diagnosis. The sooner the treatment is established the better the results are. Modern chemotherapeutical agents, based primarily in cyclophosphamide, bortethomid and dexametasone, produce a rapid, deep, and durable response in the majority of patients. Autologous stem cell transplantation remains restricted to selected patients who are generally without advanced cardiac amyloidosis.

[Acute gastric dilatation in a bulimic patient; systemic efects]

OBJECTIVES

To demonstrate through a clinical case the systemic effetcss and complications that can arise after an acute gastric dilatation caused by an eating binge.

CLINICAL CASE

A young woman diagnosed of bulimia nervosa presents to the emergency room after a massive food intake. She shows important abdominal distention and refers inability to self-induce vomit. A few hours later she commences to show signs of hemodynamic instability and oliguria. A CT scan is performed; it shows bilateral renal infarctions due to compression of the abdominal aorta and some of its visceral branches.

INTERVENTIONS

The evaluation procedures included quantification of the gastric volume by CT. A decompression gastrostomy was performed; it allowed the evacuation of a large amount of gastric content and restored blood supply to the abdomen, which improved renal perfusion.

CONCLUSIONS

CT is a basic diagnostic tool that not only allows us to quantify the degree of acute gastric dilatation but can also evaluate the integrity of the adjacent organs which may be suffering compression hypoperfusion.
