Does a liquid supplement improve energy and protein consumption in nursing home residents?

One popular strategy to improve the acceptance and efficacy of oral liquid supplements in long-term care is dispensing them during the medication pass, although few studies support its effectiveness. This study evaluated the impact of a supplement medication pass program on energy and nutrient consumption and weight in nursing home residents. Findings indicate that residents maintained their prestudy weight and had a 29% decrease in supplement energy intake, a 19% increase in food energy intake, and a 17% decrease in net energy intake (supplement plus food). Supplement and food protein intake remained stable. Over longer periods, this reduced energy consumption could lead to weight loss, so routine monitoring and periodic evaluations of resident intake (both food and supplement) are recommended to ensure residents are receiving and consuming adequate amounts of daily energy and nutrients.

[Clinical significance of fluoroscopic patterns specific for the mitotic spindle in patients with rheumatic diseases].

OBJECTIVE: To determine the clinical significance of anti-NuMA and anti-HsEg5 antibodies in a group of patients affected with rheumatic diseases. MATERIALS AND METHODS: Indirect immunofluorescence on HEp-2000 cells at serum dilution of 1:40 was used to examine 26 sera which had previously showed a "mitotic spindle" fluoroscopic pattern type during laboratory routine. RESULTS: 21 sera (80,7%) were identified with NuMA and 5 (19,3%) with HsEg5 patterns alone or associated with other ANA patterns. However only patients with isolated positivity and that is 15 with NuMA and 4 with HsEg5 stainings were included in this study. Of the NuMA positive patients 5 were affected with arthropathies associated to different forms of thyroiditis, 2 with seronegative arthritis, 2 with antiphospholipid syndrome, 1 with systemic lupus erythematosus (SLE), 1 with rheumatoid arthritis, 1 with sicca syndrome, 1 with undifferentiated connective tissue disease, 1 with Mycoplasma pneumoniae infection and 1 with retinal thrombosis. Of the HsEg5 positive patients 3 were affected with SLE and 1 with seronegative arthritis. CONCLUSIONS: NuMA does not prevail in any defined rheumatic disease, while HsEg5 staining were more frequent (75%) in patients affected with SLE all of whom showing high antibody titres.

[Acute abdomen and diabetic patients--difficulties of diagnosis and therapeutical decision].

We present a retrospective study based on 50 diabetic patients with acute abdominal diseases. Usually, clinical features were not typical, without defining signs of acute abdomen, despite frequent severe anatomo-pathological forms (6 of 12 acute appendicitis were gangrenous, with generalised or localised peritonitis; 15 of 22 acute colecystitis were gangrenous). In diabetic patients, with metabolic disorders and cetoacidosis, positive diagnosis and the decision of laparotomy are difficult problems, often delated, with a negative influence on the evolutions and prognosis of these patients.

[Abdominal hemangiopericytomas].

We present two cases of hemangiopericytoma, which are analyzed according to medical literature, although only few cases have been reported. Clinical, imagistic and histological findings of these rare vascular tumors are discussed.

[Small bowel tumors -- peculiarities of diagnosis and evolution].

The authors analyze 13 cases of small bowel tumors. There are emphasized the difficulties of diagnosis, which is rarely established before the laparotomy. In the same time, clinical features are few and operations are often performed too late, in emergency, due to tumors complications (perforation, bleeding, occlusion). There are also presented new etiopathogenic hypothesis, recently mentioned in literature. Surgical treatment is followed by many post-operative complications. Five-years survival is low, under 40% of patients.

[An autochthonous case of amebic hepatic abscess with pleural dissemination].

The present paper reports on the first autochtonous case of amoebic hepatic abscess in Romania in a patient in which the epidemiologic survey showed that there had been no possible import infection. The amoebic abscess was located in the superoexternal area of the right hepatic lobe. Subsequently a major complication developed: a tendency to pleuropulmonary invasion with the formation of fluid in the right pleural cavity. The diagnosis, suggested by the aspect of the abscess cavity, was established by the presence of the parasite in the flaky pleural exudate obtained by puncture, by cultures in Loeffler medium and by serum immunofluorescence. The abscess was evacuated surgically and a specific treatment with Chloroquine and Metronidazol combined with antibiotics and a symptomatic medication was prescribed. The patient recovered and was discharged 51 days after surgery.

[Surgical rehabilitation of nonfunctioning bilio-digestive shunts].

The authors consider the internal biliary derivations as a choice procedure for the resolution of various pathological conditions of the biliary pathways and of the pancreas. They are based on the experience accumulated in the course of a total of 416 derivations performed in the last 10 years. The confrontation with particular problems raised by 40 re-interventions for failure of internal biliary derivations has determined an analysis of causes, clinical manifestations and possibilities to solve the disturbances. Categories are discussed, in which these patients can be classified and clinical observations are presented, in connection with the etiopathogeny of the non-functioning of the derivations. Possibilities are also presented for the resolution of the problems in each particular case. Two technical possibilities are presented for the correction of non-functioning biliary-digestive anastomoses, by performing bilio-biliary anastomoses.

[Surgical reoperation after vagotomy].

In 39 cases of re-interventions carried out after vagotomy (of which 31 were patients hospitalized in the Clinic and represent 8,6% of the total 358 vagotomies performed), the experience, the viewpoints and the recommendations of the authors are presented. Early re-interventions were necessayr because of complications which are common to abdominal surgery and only in a much lower degree to accidents that can be attributed to vagotomy or the associated intervention. Late re-interventions (26 cases) were necessary in 20 cases for ulcer recidives (13 for vagotomies performed in the Clinic and 7 for vagotomies performed in other units) while late-re-interventions for dumping syndrome, cholelythiasis, etc. represented only isolated cases in these statistics.

[The synthesis of aldoxime ester derivatives with biological activity].

Continuing our investigations for obtaining etheric derivatives from the oximes of some carbonylic compounds, five carboxymethylic ethers of some aldoximes were synthetized. Their structure was confirmed by chemical and spectral analyses. The antimicrobial activity of the obtained products towards 6 microorganisms species was determined.
