Characteristics and Therapeutic Needs of Older Patients with Oropharyngeal Dysphagia Admitted to a General Hospital

BACKGROUND

Oropharyngeal dysphagia (OD) is a prevalent geriatric syndrome causing severe nutritional and respiratory complications.

OBJECTIVE

We aimed to describe the characteristics and therapeutic needs of older patients with OD admitted to a general hospital.

DESIGN, PARTICIPANTS AND MEASUREMENTS

Prospective cohort study with patients (≥70 years) with OD consecutively admitted to a general hospital. OD was clinically assessed with the Volume-Viscosity Swallowing Test and nutritional status with the Mini Nutritional Assessment-short form. Oral health (OH) and periodontal diseases were evaluated by dentists. Functionality, frailty, sarcopenia, comorbidities, dehydration, quality of life (QoL) and mortality were also assessed.

RESULTS

We included 235 patients (87.3±5.5 years) with OD hospitalized for acute diseases (9.6±7.6 days). On admission, they had low functionality (Barthel: 51.3±25.1), frailty (Fried: 3.9±0.9; Edmonton: 10.3±2.7, 87.2-91.1% frail) and high comorbidities (Charlson: 3.7±2.0). Moreover, 85.1% presented signs of impaired safety and 84.7% efficacy of swallow. Up to 48% required fluid adaptation with a xanthan gum-based thickener (89.4% at 250 mPa·s; 10.6% at 800 mPa·s) and 93.2% a texture-modified diet (TMD) (74.4%, fork-mashable; 25.6%, pureed). A total of 98.7% had nutritional risk, 32.3% sarcopenia and 75.3% dehydration. OH was moderate (Oral Hygiene Index-simplified: 2.0±1.3) and 67.4% had periodontitis. QoL self-perception was 62.2% and 5.5% of patients died during hospitalization.

CONCLUSION

Hospitalized older OD patients have impaired safety of swallow, frailty, malnutrition, dehydration, low functional capacity and poor OH and high risk of respiratory infections. They need a multimodal intervention including fluid thickening, TMD, thickened oral nutritional supplementation and OH care to improve health status and reduce OD-associated complications.

Raman spectroscopic determination of inosine nucleoside in nucleotides

Raman spectroscopy has been applied to the analytical determination of inosine nucleoside in nucleotides. Spectral characteristics of aqueous solutions of lithium, potassium and magnesium salts of inosine 5'-monophosphoric acid are described. Two characteristic bands located at 1553 and 1593 cm(-1) whose frequencies are not sensitive either to the nucleotide concentration or to alkaline cations present in the medium, have been used for this purpose. The concentration ranges over which the method was applicable were 2.5-80 and 11.5-80 mg ml(-1) of inosine using the 1553 and 1593 cm(-1) bands, respectively, with relative standard deviations of 2.5 and 4.0% and detection limits of 0.25 and 1.16% (w/w). As the above bands are not generated by the standard nucleobases, this method can be applied to the quantitative determination of inosine in transfer ribonucleic acids.

The use of heart rate variability in assessing precompetitive stress in high-standard judo athletes

The objective of this study is to examine the sensitivity to and changes in heart rate variability (HRV) in stressful situations before judo competitions and to observe the differences among judo athletes according to their competitive standards in both official and unofficial competitions. 24 (10 male and 14 female) national- and international-standard athletes were evaluated. Each participant answered the Revised Competitive State Anxiety Inventory (CSAI-2R) and their HRV was recorded both during an official and unofficial competition. The MANOVA showed significant main effects of the athlete's standard and the type of competition in CSAI-2R, in HRV time domain, in HRV frequency domain and in HRV nonlinear analysis (p<0.05). International-standard judo athletes have lower somatic anxiety, cognitive anxiety, heart rate and low-high frequency ratio than national-standard athletes (p<0.05). International-standard athletes have a higher confidence, mean RR interval, standard deviation of RR, square root of the mean squared difference of successive RR intervals, number of consecutive RR that differ by more than 5 ms, short-term variability, long-term variability, long-range scaling exponents and short-range scaling exponent than national-standard judo athletes. In conclusion, international-standard athletes show less pre-competitive anxiety than the national-standard athletes and HRV analysis is sensitive to changes in pre-competitive anxiety.

[Attention deficit/hyperactivity disorder: burden of the disease according to subtypes in recently diagnosed children]

INTRODUCTION

Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with deterioration of several dimensions of quality of life (QoL) and with the development of comorbid psychiatric disorders. The objective of the present study is to evaluate the burden of illness of ADHD subtypes in untreated newly diagnosed children in Spain.

METHODS

We recruited 124 children (80 combined, 25 inattentive and 19 hyperactive-impulsive subtype) aged 6-12 years with untreated newly diagnosed Diagnostic and Statistical Manual of Mental Disorders, 4th edition DSM-IV) ADHD. We collected socio-demographic, clinical (Attention-Deficit/Hyperactivity Disorder Rating Scale ADHD-RS], Conner's Parent Rating Scale-Revised: Short Form [CPRS:R-S], Clinical Global Impression-Severity [CGI-S], Kiddie Schedule for Affective Disorders and Schizophrenia for School Aged Children-Present and Lifetime Version [K-SADS-PL], intelligence Quotient [IQ]), Quality of Life (QoL), Child Health Questionnaire-Parent Form 50 CHQ-PF50), academic performance and health care resources utilization data. We investigated the correlations between ADHD symptom severity and QoL, academic performance and time from onset of symptoms to diagnosis.

RESULTS

QoL of children with combined-type ADHD was rated as significantly worse in patients with predominance of hyperactivity/impulsivity for most of the domains. Inattentive-type children also had worse ratings than patients with hyperactivity/impulsivity predominance in most of the domains. The ADHD Index of Conner's Parent Rating Scale-Revised: Short Form (CPRS-R:S) was significantly lower in hyperactive/impulsive patients. We found no differences across subtypes in IQ, academic performance and health care resources utilization. Higher ADHD symptom severity was associated to poor QoL.

CONCLUSIONS

Combined and inattentive subtypes are associated with greater disorder severity, more comorbid psychiatric disorders, and worse QoL than the subtype with hyperactivity/impulsivity predominance.

[Effectiveness results of olanzapine in acute psychotic patients with agitation in the emergency room setting: results from NATURA study]

INTRODUCTION

Patterns of use of antipsychotics are not well described in emergency units. The objective of this study was to describe the effectiveness and safety of use of olanzapine in patients with acute psychosis and agitation in the emergency rooms.

METHODS

In this prospective observational study 278 patients with acute psychosis and agitation were consecutively admitted in 16 psychiatric emergency wards and treated with any oral psychopharmacology treatment, including olanzapine, according to investigators clinical criteria. Data were collected prospectively including demographics, diagnosis, concomitant medications, utilization of mechanical restraints, and severity of agitation. Clinical evolution during emergency room stay was assessed with PANSS-Excitement Component, CGI-S and Agitation and Calmness Evaluation Scale (ACES) at baseline, before any re-intervention (if needed) and at discharge from the emergency room. Safety was also evaluated.

RESULTS

Olanzapine alone was used in 148 (53.2%) patients. Most of them (77.7 %) were diagnosed of Schizophrenia and related psychoses. Up to 38 patients (25.7 %) required mechanical restraints. Mean change (confidence interval [CI] 95 %) from baseline to discharge was significant in all rating scales; PANSS-EC: -7.46 (-8.2, -6.7); CGI-S: -1.82 (-2, -1.6) ACES: 1.28 (1.1, 1.5). At discharge 70.3% of patients went to inpatient units. Five patients (3.4%) reported adverse events including: bradycardia, dry mouth, sedation, hypertension, hypotension, and orthostatic hypotension. None of them was serious.

CONCLUSIONS

The utilization of olanzapine alone decreased agitation in psychotic patients in emergency room settings. Incidence of adverse events was low and it was well tolerated.

[Quality of life and social functioning in schizophrenic patients treated with olanzapine: 1 year follow-up naturalistic study]

OBJECTIVE

To measure health related quality of life (HRQL) and social functioning in schizophrenic patients treated with olanzapine under regular clinical practice conditions.

METHODS

Out-patients diagnosed of schizophrenia and beginning treatment with olanzapine, quetiapine, risperidone or typical oral antipsychotics were included. Information on socio-demographic characteristics was obtained and in each visit (baseline, 3, 6 and 12 months) they were administered the generic HRQL questionnaire Euro-QoL-5D (EQ-5D) and the Social Functioning Scale (SFS).

RESULTS

A total of 1,198 patients were followed-up for 12 months. Mean age (SD) was 38.6 (13.3) years and 62.9 % of them were men. In basal conditions the most affected dimensions of EQ-5D were anxiety/depression (76 %), and daily activities (73.6 %). After 12 months treatment the cohort of patients treated with olanzapine showed a better HRQL in the self-care dimension compared to all other treatments (p < 0.05), and in the dimensions of pain/discomfort, anxiety/depression and usual activities compared to the group treated with quetiapine and risperidone (p < 0.05). The Visual Analogue Scale (VAS) of the EQ-5D questionnaire showed a better health state after 12 months in the group treated with olanzapine compared to the groups of quetiapine or risperidone (p < 0.05). The SFS showed a better improvement in the cohort of olanzapine in the three studied dimensions after 12 months: isolation and social relationships in comparison to the risperidone group (p < 0.05), interpersonal communication in comparison to the risperidone and quetiapine group (p < 0.05) and independence performance in comparison to all the other treatments (p < 0,05).

CONCLUSION

Schizophrenic patients treated with olanzapine for one year show a better improvement in HRQL and social functioning than those treated with other antipsychotics.

Pharmacological Management of Acutely Agitated Schizophrenic Patients

Agitation is commonly seen in acute schizophrenic patients and core symptoms include a wide range of symptom. It requires rapid and effective treatment approaches in order to protect patient and caregiver from potential injury. Clinician's decision of pharmacological treatment should be individualized to the needs and circumstances of the patient. Benzodiazepines, typical antipsychotics, and combinations of typical antipsychotics and benzodiazepines have been widely used as treatment options. Atypical antipsychotics have clear advantages over the typical drugs as they generally show a much better safety and tolerability profile, particularly to EPS and related side effects, however clinical perception regarding efficacy in treating acutely agitated psychotic patient is controversial. New intramuscular atypical antipsychotic formulations offer evidence of being at least as effective as typical antipsychotics in controlling agitation. Therefore, they should be considered as first line therapy in agitated schizophrenic patients.

[Atomoxetine safety and efficacy in children with attention deficit/hyperactivity disorder (ADHD): initial phase of 10-week treatment in a relapse prevention study with a Spanish sample]

INTRODUCTION

Attention-deficit/hyperactivity disorder (ADHD) appears to be associated to problems with regulation of cortical dopaminergic/noradrenergic function. The purpose of this work is to present efficacy and safety data from 10-week open label treatment with atomoxetine, a highly selective norepinephrine reuptake inhibitor, in a Spanish sample of children and adolescents with ADHD participating in a double-blinded, placebo-controlled, multinational study on relapse prevention.

PATIENTS AND METHODS

Sub-analysis of data in 36 children and adolescents aged 6 to 15 years, with diagnosis of ADHD (DSM-IV) included in Spain, receiving open-label treatment with atomoxetine for 10 weeks and assessed using ADHD-RS, CGI-ADHD-S, CPRS-R:S, CTRS-R:S y CHQ-PF50.

RESULTS

After 10 weeks of treatment with atomoxetine, statistically significant reductions in ADHD-RS, CGI-ADHD-S, CPRS-R:S and CTRS-R:S scores were obtained in both subtypes; 87.5 % of inattentive patients and 82.14 % of patients with combined subtype were responders. No recurrences were observed. No serious adverse event-driven discontinuations occurred, and no statistically significant changes in blood pressure, but a mild increase in heart rate (p < 0.0001) were observed.

CONCLUSIONS

In general, atomoxetine was well tolerated and effective in the open phase in Spanish patients, both for inattentive and combined subtypes. Atomoxetine appears as a non-stimulant therapeutic alternative for the treatment of ADHD.

[Three cases of congenital cutaneous candidosis]

We report three cases of term newborns with Congenital Cutaneous Candidosis (CCC) occured in a ten months period. Two of these showed respiratory distress that require mechanical ventilation and the administration of exogenous surfactant in one case. All the three cases recovered after therapy with fluconazole. Early onset of severe respiratory distress may require intubation and mechanical ventilation, and systemic involvement requires systemic antimichotic therapy. We did not find any predisposing factors of such a rare disease, in spite of the occurrence of three cases in a short period of time.

Treatment of severely psychotic inpatients with schizophrenia: olanzapine versus other antipsychotic drugs

Nine hundred and ten schizophrenic inpatients suffering from acute psychotic episodes were included in a naturalistic study. Patients were prescribed treatment with olanzapine (OLZ) or with typical antipsychotic (TYP) drugs. Patients receiving another atypical antipsychotic were excluded. Of the whole sample, 483 (53.4%) were treated with olanzapine and 421 (46.6%) with typical antipsychotics. Three specific subpopulations of greater severity were defined: patients with prominent psychotic symptoms, agitated patients, and patients initially treated with intramuscular (i.m.) medication because of their acute clinical condition. Severity of illness was assessed using the Clinical Global Impression (CGI) scale for severity, the Brief Psychiatric Rating Scale (BPRS) and the Nursing Observational Scale for Inpatient Evaluation. Baseline differences were adjusted per data analysis. The mean change from baseline to endpoint of overall symptomatology (total BPRS score) was significantly greater in the olanzapine group compared to the typical antipsychotic-treated group, both in the sample of patients with prominent positive symptoms (P < 0.001) and in the sample of agitated patients (P =0.015). Significant differences were also found in BPRS positive scores, BPRS negative scores and CGI scores in these two populations. Patients who had received previous i.m. drugs showed no statistically significant differences in symptomatic improvement between both treatments groups, except for a more favourable response of BPRS negative subscores in the olanzapine group (P =0.015). The results suggest that olanzapine may be considered as a first line treatment for severely psychotic inpatients with schizophrenia.

Cardiovascular Response and Anesthetic Recovery in Electroconvulsive Therapy with Propofol or Thiopental

Propofol provokes a slight hypotensive effect that could mitigate the cardiovascular response to electroconvulsive therapy (ECT). In this study we compared the effects of propofol and thiopental for ECT anesthesia in seven women (22-67 years of age). Anesthesia was induced with either thiopental or propofol, and with atropine and suxamethonium for each treatment. The first anesthesia was assigned to thiopental or propofol at random; the next anesthesia was induced with the other drug, and alternated thereafter. Systolic blood pressure, diastolic blood pressure (DBP), and heart rate (HR) were recorded before anesthesia, after anesthetic induction, and 1 and 5 min after ECT. ECT-induced increases in DBP and HR were less marked with propofol than with thiopental. Seizure durations were decreased with propofol compared with thiopental.

Clinical and cerebral blood flow changes in catatonic patients treated with ECT

OBJECTIVE

To determine changes in clinical manifestations and cerebral blood flow (CBF) before and after administration of ECT to patients with catatonia due to schizophrenia or mood disorders.

METHODS

A sample of nine patients who met DSM-IV criteria for catatonia was studied. Patients received between 5 and 15 sessions (thrice per week) of ECT. Severity of catatonia was measured with the Modified Rogers Scale (MRS). Changes in CBF were measured with a brain single positron emission computer tomography (SPECT) that was performed 1 week before the first ECT and 1 week after the last ECT.

RESULTS

Catatonia was due to schizophrenia in five patients and mood disorders in four patients. There were no significant clinical and brain SPECT differences between these two groups before treatment. Pre- vs. post-ECT comparisons showed significant reduction of catatonic symptoms in both groups. However, patients with mood disorders needed less ECT sessions and showed greater clinical improvement. Brain SPECT showed significant increase in CBF in parietal, temporal, and occipital regions in patients with mood disorder and no significant changes in patients with schizophrenia.

CONCLUSIONS

These results support the efficacy of ECT for treatment of catatonic patients, especially secondary to mood disorders, which seem to be correlated with improvements in CBF.

A flow injection chemiluminescence method using Cr(III) as a catalyst for determining hydrogen peroxide. Application to H(2)O(2) determination in cultures of microalgae

Flow injection analysis has been applied to the determination of hydrogen peroxide produced by some different species of microalgae. The method is based on the luminol-H(2)O(2) chemiluminescence reaction using Cr(III) as a catalyst. Optimum experimental conditions for the method have been studied and trace amounts of hydrogen peroxide determined with detection limits of 4 10(-8) mol/L. The method using Cr(III) was compared with that using horseradish peroxidase as the catalyst.

Sub-clinical cerebral oedema does not occur regularly during treatment for diabetic ketoacidosis

Fulminant cerebral oedema is an uncommon, fatal complication of diabetic ketoacidosis (DKA) in children. This study aimed to find out whether the sub-clinical compression of the brain ventricles found by an earlier study, is a general phenomenon during intravenous treatment for DKA. Four boys and four girls were examined. Blood glucose values ranged from 40 to 24.6 mmol/l, base excess -34.6 to -13.6 and capillary blood pH 6.89-7.22. The patients received fluids containing both glucose and electrolytes, and insulin intravenously. After about 10h, blood glucose was 8.7-21.8 mmol/l and base excess had decreased substantially (-9.5 to -2.9) in seven of the eight cases. Computerized tomography of the brain was then performed, and again after full recovery. Only two of the patients had an initial decrease in intercaudate distance, which exceeded the variability found in a reference group. Compression of the cerebral ventricles does not occur regularly during treatment for DKA.

Physical and psychosocial functioning of 117 survivors of bone marrow transplantation

All surviving patients receiving a BMT at our center since 1976 were surveyed. Among 163 eligible patients, 145 were contacted and 117 (81%) responded. Their median follow-up was 55 months (range 6-154). The research instruments consisted of a demographic questionnaire, a current medical status form, a quality of life questionnaire (Nottingham Health Profile), and a screening instrument for psychiatric morbidity (the 28-item version of the General Health Questionnaire). Current functioning varied considerably across patients. They reported a high use of medical services (37%) and varied ongoing medical problems within the last 6 months. Most of them (93%) received Karnofsky ratings of 80 or above. Eight percent had current chronic GVHD. Comparing our patients' quality of life with a British reference population, most important differences were found for physical mobility, work, and sex life. Psychiatric morbidity in BMT survivors was higher than in a Spanish general population. Multivariate analyses revealed that a higher systemic symptomatology score, a lower educational level, an older age at BMT, a shorter time post-BMT, a female gender, and impotence were significant predictors of an impaired overall quality of life. Similarly, a higher systemic symptomatology score, a shorter time post-BMT, a higher number of major infections, and a lower educational level were predictive factors of a higher psychosocial distress. No differences in quality of life or psychosocial status between allogeneic and autologous transplants were found. Quality of life and psychosocial distress improved with the passage of time, specially within the first 3 years.

Elevated rates of early discontinuation from pharmacotherapy trials in alcoholics and drug abusers

The failure of subjects to complete clinical trials is a common problem with important implications for the interpretation of study results. Although a substantial literature exists on the high prevalence of premature termination from psychiatric and substance abuse treatment setting, there has been little attention paid to early discontinuation in clinical trials. There is evidence that the presence of substance abuse predicts higher rates of early discontinuation. This, combined with a recent increase in efforts to develop medications for treatment of substance use disorders, led us to conduct a literature review to determine whether pharmacotherapeutic trials for patients with these disorders have higher rates of premature discontinuation than comparable studies of patients with other psychiatric disorders. Of 267 articles that were initially identified, 83 met predetermined criteria for inclusion in the analysis. As hypothesized, after controlling for a number of potential contributing variables, treatment trials with substance abuse patients showed a significantly poorer retention rate than those of patients with other psychiatric diagnoses. The difference in retention rate was also evident when studies specific to alcohol dependence, the largest subgroup of substance use disorders, were evaluated separately. Although the retrospective nature of the study design limits the conclusions that can be drawn, the results suggest that, in pharmacotherapy trials with alcoholics or other substance abuse patients, particular attention should be paid to enhancing treatment retention.

Raman spectroscopic determination of thymidine nucleoside structures in nucleotides

Several spectral differences in Raman spectra were observed for thymidine (TM), 3'-O-acetylthymidine (3'OATM), 3',5'-di-O-acetylthymidine (3'5'DOATM), thymidine 5'-monophosphoric acid (H2TMP) and its Ca2+, Sr2+ and Ba2+ salts owing to nucleoside conformational differences in the thymidine moiety. The spectroscopic characterization of the nucleoside structures was made on the basis of previous crystallographic works relative to TM, 3'OATM, 3'5'DOATM and Ba(TMP).6H2O. The crystal structures of the other compounds reported here are, as yet, unknown. However, their nucleoside structures were inferred from the position of the phosphoester stretching band. The results show that C(2')-endo-anti, C(3')-endo-anti and C(2')-endo/C(3')-exo-anti puckers generate marker bands useful to characterize and titrate these thymidine nucleoside conformations. The furanose sugar puckering of the C(2')-endo-anti geometry has been suggested to account for the enhanced activity of thymidine derivatives against human immunodeficiency virus-type 1. A Raman spectroscopic method is described for the determination of this structure in thymidine nucleosides and nucleotides.

[The Silver-Russel syndrome]

The authors report a case of Silver-Russel syndrome with severe deficit growth observed since intrauterine life. They describe the major features, that are constant and the minor features, that are variable and numerous. The features not always are present at birth. The A. exclude in this case a genetic cause and suggest a possible motherly cause.

[Trabeculectomy for secondary glaucoma caused by metastasis of breast carcinoma]

A 40 year old female presented with secondary glaucoma and loss of vision due to anterior pole metastasis of breast carcinoma. Trabeculectomy was performed after chemotherapy failed to control the uveal metastases. Ocular pressure control was obtained post-surgically and resulted in excellent visual rehabilitation during the next ten months prior to her demise.
