Subacute stroke: new-onset poststroke bladder and bowel dysfunctions and possible associated factors

PURPOSE

Bladder and bowel poststroke dysfunctions negatively impact patients' health. Stroke-related characteristics associated to these dysfunctions are poorly known. This study aims to estimate the prevalence of new-onset poststroke bladder and bowel dysfunctions, characterize their associated factors, and describe the dysfunctions' clinical approach.

MATERIALS AND METHODS

Cross-sectional study including 157 patients admitted to a single hospital's stroke unit with a first-ever stroke, during 3 months. An 18-item questionnaire was applied to assess dysfunctions pre and poststroke. The McNemar test was used to compare pre and poststroke prevalence. A logistic regression was used to estimate associations (OR, 95% CI) between individual characteristics and new-onset dysfunctions.

RESULTS

We had 113 (72%) respondents. There was a significant increase in the prevalence of bladder and bowel dysfunctions poststroke (p < 0.001). Higher stroke severity was significantly associated with both new-onset poststroke bladder and bowel dysfunctions (OR = 15.00, 95% CI [4.92,45.76] and OR = 5.87,95%CI [2.14,16.12], respectively). Total anterior circulation strokes, cardioembolic strokes, and lower functionality at discharge were also significantly associated with both dysfunctions. Thirteen patients (11.5%) reported that health professionals addressed these dysfunctions.

CONCLUSIONS

Poststroke bladder and bowel dysfunctions are highly prevalent. Being aware of their epidemiology helps draw attention to patients at higher risk of developing these dysfunctions, enhancing the rehabilitation process.IMPLICATIONS FOR REHABILITATIONPoststroke bladder and bowel dysfunctions are highly prevalent and under-recognised consequences of stroke.Being aware of their epidemiology and associated factors may help identify patients at higher risk of developing these dysfunctions.It is necessary to raise clinical awareness to ensure a more efficient diagnostic and therapeutic approach, enhancing patients' rehabilitation process, quality of life and lowering collateral societal burden.

Dysphagia and pulmonary complications in acute cerebrovascular disease: A retrospective observational study

INTRODUCTION

Dysphagia is a common post-stroke complication, which may result in serious pulmonary sequelae. Early detection of dysphagia and aspiration risk can reduce morbidity, mortality and length of hospitalization.

OBJECTIVES

This study aims to identify association between dysphagia and acute cerebrovascular disease, and evaluate the prevalence and impact of pulmonary complications on readmissions and mortality.

MATERIAL AND METHODS

Retrospective observational study based on 250 clinical records of patients with acute cerebrovascular disease: clinical history, neurological examination, imaging and Gugging Swallowing Screen in the first 48h. Patients were followed for 3 months via medical records to estimate 3-month mortality and readmissions.

RESULTS

Out of 250 clinical records analyzed, 102 (40.8%) were evaluated for dysphagia. The prevalence of dysphagia was 32.4%. The risk was higher in older patients (p<0.001), in severe stroke (p<0.001) and in the hemorrhagic subtype (p=0.008). An association was found with dysarthria and aphasia (p=0.003; p=0.017). Respiratory tract infections occurred in 14.4% of all patients (GUSS group 11.8% versus no GUSS group 16.2%), and in 75% of those with severe dysphagia (p<0.001). Mortality at 3 months was 24.2% in dysphagic patients, especially high in the severe dysphagia group (75%, p<0.001).

CONCLUSIONS

The type of cerebrovascular disease, NIHSS and GCS scores, age, dysarthria, and aphasia were significant associated factors to dysphagia. The prevalence of respiratory tract infections was higher in patients with no GUSS record, and no statistical significance was observed in related readmissions. Mortality at 3 months was superior in the severe dysphagia group.

Can Failed Back Surgery Syndrome Be Healed by Transverse Myelitis?

Failed back surgery syndrome (FBSS) is a condition characterized by persistent or recurring back pain following spinal surgery. Etiological factors for FBSS are being studied by investigators and clinicians in an attempt to organize them based on their temporal relation to the surgery event. However, many questions regarding the pathophysiology of FBSS remain, which has resulted in a lack of efficacy among its treatment options. In this report, we present a remarkable case of longitudinally extensive transverse myelitis (LETM) in a patient with a medical history of FBSS who was taking multiple pain medications but had persisting pain. The patient, a 56-year-old woman, presented with an incomplete motor injury (American Spinal Injury Association Impairment Scale D) and a neurological level of C4. Investigations revealed an idiopathic LETM that was unresponsive to high doses of corticosteroids. An inpatient rehabilitation program was initiated, resulting in favorable clinical progress. The patient no longer complained of back pain, and her pain medication was gradually discontinued. At the time of discharge, the patient was able to walk with a stick, dress and groom herself independently, and eat with an adapted fork without experiencing pain. As the pain mechanisms underlying FBSS are complex and not yet fully understood, this clinical case aims to contribute to the discussion of possible pathological mechanisms implicated in LETM that may have contributed to the shutdown of pain perception in a patient with a history of FBSS. By doing so, we hope to identify new and effective ways to treat FBSS.

Determining the 4th limiting amino acid in low crude protein diets for male and female Cobb MV × 500 broilers

1. Four experiments were conducted to determine the 4th limiting amino acid (AA) in maize-soybean meal-based diets. 2. Deletion assay methodology was used to quantify performance and carcase trait responses to potential deficiencies in essential and conditionally essential AA caused by reductions in dietary crude protein of maize-soybean meal-based diets from 202.9 to 186.5 g/kg. 3. The deletion of Val, Phe and Gly + Pro resulted in negative effects on live performance and carcase traits for male broilers, whereas AA deletion only affected wing weights for females with no response on live performance. 4. Further experimentation could not duplicate a response to Phe or Pro in male broilers. 5. Valine was identified as the potential 4th limiting AA in maize-soybean meal-based diets and was not found to be co-limiting with Ile.

Non-cellulosic polysaccharide content in feed ingredients and ileal and total tract non-cellulosic polysaccharide digestibility in 21- and 42-day-old broilers fed diets with and without added composite enzymes

An initial study profiled non-cellulosic polysaccharide (NCP) levels in feed ingredient samples-corn, soybean meal (SBM), whole soybean, and distillers dried grains with solubles (DDGS). A separate NCP digestibility assay was performed in broilers at day 21 (grower phase) and day 42 (finisher phase) fed corn-soy based diets with and without composite enzymes (phytases, multi-carbohydrases, and proteases). Negative control (NC), NC + composite enzymes (NC+E), and positive control (PC) diets were tested. Negative control and NC + E diets were isocaloric, 3,020 kcal/kg ME at grower phase and 3,026 kcal/kg ME at finisher phase. Positive control diet was formulated to meet the Cobb standard nutrient specifications. Diets, pooled digesta, and excreta samples from all treatment diets were collected from 21- and 42-day-old birds and NCP content analyzed as soluble NCP (S-NCP) and insoluble NCP (I-NCP) fractions. Digestibility coefficient (DC) values were determined for all dietary treatments for both the feeding periods. Results from the ingredient analysis showed NCP levels of ∼7 to 10% in corn samples, ∼8 to 11% in SBM samples, ∼11 to 14% (including pectin level) in whole soybean, and ∼12 to 17% in DDGS samples, suggesting variation (P < 0.05) in NCP levels existed within ingredient samples. Digestibility assays showed that enzyme treated (NC + E) diet improved DC values at day 21 from 6 to 10 units and 6 to 9 units for ileal and total tract collection, respectively, for I-NCP fraction (P < 0.05) compared to DC values for NC or PC diets. The ileal DC values at day 42 were not different between treatment diets (∼0.6) but total tract DC values improved 9 to 11 units for broilers fed NC + E diet compared to NC or PC diets. Higher DC values for S-NCP were observed for all treatments for both feeding periods (∼0.7-ileal and ∼0.8-total tract) compared to DC values for I-NCP. Overall, the use of supplemental enzymes in corn-soy-based diets showed improvement in total NCP digestion.

Prevalence of vitamin D deficiency amongst soccer athletes and effects of 8 weeks supplementation

BACKGROUND

High prevalence of vitamin D deficiency is well known around the world in risk populations. Although less is known about the athletic population, some studies report vitamin D deficiency amongst athletic population and adequate vitamin D levels are crucial for athletic population as they can prevent injuries such as stress fractures and might even have ergogenic effects for example on muscle function. The main objectives were to evaluate the basal serum levels of 25(OH)D and calcium in professional soccer athletes on the latitude 40°N, to evaluate the effects in 25(OH)D and calcium serum levels following supplementation of 1667 IU/day of cholecalciferol during a period of 8 weeks and evaluate eventual toxicity arising from it.

METHODS

Twenty-eight professional athletes were evaluated according to the skin type. Basal serum levels of 25(OH)D and calcium were evaluated during winter months. Athletes were then supplemented with cholecalciferol 25.000 IU every two weeks. Serum levels of 25(OH)D and calcium were evaluated after supplementation.

RESULTS

25(OH)D initially ranged between 9.9 ng/mL and 32.9 ng/mL with a median of 19.2 IQR 7.24 ng/mL. A statistically significant inverse correlation exists between vitamin D deficiency and the Fitzpatrick Scale (ρ=-0.555 P=0.003). After 8 weeks, 25(OH)D ranged between 10.6 ng/mL and 43.4 ng/mL with a median of 33.2 ng/mL IQR 6.1 ng/mL. We verified a statistically significant increase of serum 25(OH) D levels (11.74±5.988; CI 95% [9,02; 14,47]; P<0.001. In addition, there was a statistically significant reduction of calcium: -0.36±0.457; CI 95% [- 0.57; -0.15]; P=0.002.

CONCLUSIONS

Professional athletes have a high prevalence of vitamin D deficiency. Supplementation with cholecalciferol in winter months during 8 weeks is safe and effective in raising 25(OH)D serum levels. However, it may not be sufficient for athletes to reach adequate vitamin D levels.

[Devic's disease]

Devic's disease, also known as Neuromyelitis Optica, is a demyelinating disease of the central nervous system, with selective involvement of the spinal cord and optic nerves. The authors describe a clinical case of acute myelitis, initially approached in the context of a nonspecific syndrome gripal, with subsequently sudden bilateral amaurosis, which leads to the diagnosis hypotesis of Devic's disease, a disease with poor prognosis in optic-spinal function and adequate symptomatic treatment.

Can we improve gait skills in chronic hemiplegics? A randomised control trial with gait trainer

AIM

Partial body weight support (PBWS) is an accepted treatment for hemiplegic patients. The aim of this study is to compare the efficiency of gait trainer with conventional treatment on the gait management after stroke.

METHODS

Forty chronic post-stroke hemiplegics were part of a prospective research. Inclusion criteria were: first ever stroke in a chronic stage with stabilised motor deficits; age >18 and <80 years; cognitive and communication skills to understand the treatment; absence of cardiac, psychological and orthopedic contraindications. Patients were randomised into two groups: the control group (CG) that used the Bobath method in 40 minutes sessions, 5 times a week, for 5 weeks, and the experimental group (EG) that used the gait trainer, for the same period of time and frequency. Assessment tools: Motricity Index (MI); Toulouse Motor Scale (TMS); modified Ashworth Spasticity Scale (mASS); Berg Balance Scale (BBS); Rivermead Mobility Index (RMI); Fugl-Meyer Stroke Scale (F-MSS); Functional Ambulation Category (FAC); Barthel Index (BI); 10 meters, time up and go (TUG), 6 minutes, and step tests. EG and CG did the assessments before treatment (T(0)), right after treatment (T(1)), and on follow-up, 3 months later (T(2)).

RESULTS

CG and EG were homogenous in all the variables at T(0). CG and EG showed improvement in almost all the assessment scales after treatment, although only some with relevant differences. EG showed statistically relevant improvement on T(1) and on T(2) in several of the assessment tools, whereas CG only showed statistically significant improvement after T(1) and only in some of the assessment tools.

CONCLUSIONS

Both groups of chronic hemiplegic patients improved after either PBWS with gait trainer or Bobath treatment. Only subjects undergoing PBWS with gait trainer maintained functional gain after 3 months.

[Neurocysticercosis]

The neurocysticercosis is an infestation of the central nervous system by larvae of Taenia solium. The disease is endemic in a few countries of Latin America, Asia, and Africa and is becoming increasingly prevalent in the United States and Europe. The immigration of individuals from endemic areas and the tourism in these areas require a good knowledge of this disease. A retrospective study evaluating the neurocysticercosis lesions with MR and CT is proposed. Parenchymal, subarachnoid and intraventricular cysts are evaluated. We were able to recognise four CT and MR stages. MR was useful in detecting the cysts of neurocycticercosis in the first stage but was inferior in the detection of parenchymal calcifications.
