RESUMO

OBJECTIVE: To evaluate the efficacy of a therapeutic intervention based on self-adjustment strategies for improving of symptomatic severity and quality of life. METHODS: The study was a randomised single-blind clinical trial. Quality of life, disability, and functional impairment were collected. The control group received a leaflet with information on the main symptoms of Long-COVID-19 syndrome, in addition to standard medical treatment. The intervention group received treatment following a dual approach; on the one hand, monitoring and recognition of symptomatology and on the other hand, adaptation and functional improvement. RESULTS: A total of 54 participants were included, 27 were included in the intervention group and 27 in the control group. At the beginning of the study, no significant differences were found between groups. After intervention, the quality of life variable showed significant differences between groups in the self-care and anxiety/depression dimensions. Significant between-groups differences were also found for the self-care subscale of the disability variable. The intervention group showed significant differences from baseline on some subscales of the quality of life, disability, and functional impairment variables. CONCLUSION: Strategies based on lifestyle adjustments are adequate for the improvement of quality of life and symptom severity in the long COVID-19 population. PRACTICE IMPLICATION: The findings suggest that applying an intervention focused in self-adjustment for long COVID patients can have positive effects.

RESUMO

OBJECTIVE: To evaluate the effectiveness of a self-management treatment added to a physical therapy program compared to a physical therapy program in patients with chronic neck pain. METHODS: Fifty-three patients with chronic neck pain were randomly allocated to a physical therapy intervention (control group) or an individualized self-management combined with physical therapy intervention (experimental group). Both interventions were developed over a four-week period. Outcome measures included were Disability, Fear-Avoidance Beliefs, Health-Related Quality of Life, Pain, and Anxiety and Depression. All outcomes were measured before and after the treatment and at three-month follow-up. RESULTS: There were not significant differences between groups at baseline. After the intervention both groups obtained better results in the Neck Disability Index but there were not significant differences between them (p > 0.05). At follow-up, the self-management group obtained significant better results compared to the control group (95 % CI: -5.20(-6.8 to -1.5), p = 0.032). CONCLUSIONS: An individualized self-management program added to a physical therapy program led to a greater improvement in disability at 3 months follow up compared to a physical therapy program alone. Catastrophizing, pain, and health-related quality of life improved significantly after the intervention and at follow-up compared to the standard care alone. PRACTICAL IMPLICATIONS: This study indicates that physical therapy for patients with chronic neck pain preferably should include self-management education.

RESUMO

OBJECTIVE: Patients with stroke frequently present postural control impairment. This review aimed to assess the effectiveness of core exercising on postural control in patients with stroke. TYPE: Systematic review and meta-analysis. LITERATURE SURVEY: Systematic review in the following databases: PubMed/MEDLINE, Web of Science, ScienceDirect, CINAHL, Scopus, and Physiotherapy Evidence Database (PEDro). Studies up to July 2019 were included. METHODOLOGY: Studies were included if the sample was composed of adults with stroke, the intervention followed a core exercising approach (alone or combined with another intervention), and the study was a randomized controlled trial including at least one measurement related to posture control. Studies were independently screened for inclusion and data were extracted by two researchers, with a third researcher arbitrating any disputes. Study quality was assessed using the Downs and Black scale. SYNTHESIS: After screening of 1540 records, a total of 14 studies met the specified inclusion criteria and involved 520 participants. Two studies exhibited "excellent" quality and five exhibited "poor" quality. The meta-analysis was performed with data from the Trunk Impairment Scale (mean difference 0.98; 95% confidence interval, 0.69 to 1.27; P < .001), Berg Balance Scale (mean difference 0.27; 95% confidence interval, -0.25 to 0.79; P = .317), and Timed Up and Go test (mean difference -0.09; 95% confidence interval, -0.49 to 0.31; P = .656). The results favored core exercising alone or in combination with proprioceptive neuromuscular facilitation when compared with conventional training or proprioceptive neuromuscular facilitation in patients with stroke. No significant differences in total values were found in the other measures. CONCLUSIONS: The studies reviewed suggest that core exercising alone or in combination with other therapies had an impact on trunk performance when compared with conventional training in patients with stroke. However, total analyses did not show significant differences for the other measures related to balance ability analyzed.

RESUMO

BACKGROUND: Upper limb disturbances are prevalent in patients with Parkinson disease (PD) and can limit their participation in activities of daily living. Tele-assessment of upper limb motor symptoms using an Internet application may be an alternative for addressing the growing demand for monitoring of disease progression. OBJECTIVE: To evaluate the level of agreement between face-to-face and tele-assessment of patients with PD. DESIGN: Reliability study. SETTING: Parkinson's Disease Association. PARTICIPANTS: Twenty-one patients with PD from a local association participated in the study. METHODS: Patients attended a session for clinical face-to-face and real-time online tele-assessment. MAIN OUTCOME MEASUREMENTS: Upper limb measures of function (assessed with the Manual Ability Measure 16), dexterity (evaluated using the coin rotation task), motor speed (assessed by the finger tapping test), tremor (evaluated with the Fahn-Tolosa-Marin Tremor Rating Scale), and range of motion (using the Kinovea software) were recorded by two independent researchers. RESULTS: All the outcome measures evaluated showed a good interrater, intraclass correlation coefficient (ρ > 0.75). In addition, most confidence intervals were narrow and excluded 0.8. The lowest reliability was obtained for elbow flexion of the most affected upper limb (ρ = 0.75; confidence interval 0.49-0.89) and the highest reliability for finger tapping tests (ρ = 1; 1, 1). CONCLUSIONS: This study demonstrates high interrater reliability of upper limb tele-assessment in patients with PD compared to a face-to-face assessment. LEVEL OF EVIDENCE: III.

RESUMO

OBJECTIVE: To investigate the effects of a Pilates exercise program on disability, pain, lumbar mobility, flexibility and balance in patients with chronic non-specific low back pain. DESIGN: Randomized controlled trial. SETTING: University laboratory. PARTICIPANTS: A total of 54 patients with chronic non-specific low back pain. INTERVENTION: Patients were randomly allocated to an experimental group ( n=27) included in a Pilates exercise program or to a control group ( n=27) receiving information in a form of a leaflet. MAIN OUTCOME MEASURES: Disability (Roland-Morris Disability Questionnaire and Oswestry Disability Index), current, average and pain at it least and at its worst (Visual Analogue Scales), lumbar mobility (modified Shober test), flexibility (finger-to-floor test) and balance (single limb stance test) were measured at baseline and after the intervention. RESULTS: A between-group analysis showed significant differences in the intervention group compared to the control group for both disability scores, the Rolland-Morris questionnaire (mean change±standard deviation of 5.31±3.37 and 2.40±6.78 respectively and between-groups mean difference of 3.2 ± 4.12, p=0.003) and the Oswestry Disability Index ( p<0.001), current pain ( p=0.002) and pain at it least ( p=0.033), flexibility (0.032) and balance (0.043). CONCLUSIONS: An 8-week Pilates exercise program is effective in improving disability, pain, flexibility and balance in patients with chronic non-specific low back pain.

RESUMO

PURPOSE: Despite growing evidence regarding nonsynostotic plagiocephaly and their repercussions on motor development, there is little evidence to support the use of manual therapy as an adjuvant option. The aim of this study was to evaluate the effects of a therapeutic approach based on manual therapy as an adjuvant option on treatment duration and motor development in infants with severe nonsynostotic plagiocephaly. METHODS: This is a randomised controlled pilot study. The study was conducted at a university hospital. Forty-six infants with severe nonsynostotic plagiocephaly (types 4-5 of the Argenta scale) referred to the Early Care and Monitoring Unit were randomly allocated to a control group receiving standard treatment (repositioning and an orthotic helmet) or to an experimental group treated with manual therapy added to standard treatment. Infants were discharged when the correction of the asymmetry was optimal taken into account the previous clinical characteristics. The outcome measures were treatment duration and motor development assessed with the Alberta Infant Motor Scale (AIMS) at baseline and at discharge. RESULTS: Asymmetry after the treatment was minimal (type 0 or 1 according to the Argenta scale) in both groups. A comparative analysis showed that treatment duration was significantly shorter (p < 0.001) in the experimental group (109.84 ± 14.45 days) compared to the control group (148.65 ± 11.53 days). The motor behaviour was normal (scores above the 16th percentile of the AIMS) in all the infants after the treatment. CONCLUSIONS: Manual therapy added to standard treatment reduces the treatment duration in infants with severe nonsynostotic plagiocephaly.

RESUMO

In the adult brain, neurons require local cholesterol production, which is supplied by astrocytes through apoE-containing lipoproteins. In Huntington's disease (HD), such cholesterol biosynthesis in the brain is severely reduced. Here we show that this defect, occurring in astrocytes, is detrimental for HD neurons. Astrocytes bearing the huntingtin protein containing increasing CAG repeats secreted less apoE-lipoprotein-bound cholesterol in the medium. Conditioned media from HD astrocytes and lipoprotein-depleted conditioned media from wild-type (wt) astrocytes were equally detrimental in a neurite outgrowth assay and did not support synaptic activity in HD neurons, compared with conditions of cholesterol supplementation or conditioned media from wt astrocytes. Molecular perturbation of cholesterol biosynthesis and efflux in astrocytes caused similarly altered astrocyte-neuron cross talk, whereas enhancement of glial SREBP2 and ABCA1 function reversed the aspects of neuronal dysfunction in HD. These findings indicate that astrocyte-mediated cholesterol homeostasis could be a potential therapeutic target to ameliorate neuronal dysfunction in HD.

RESUMO

Given the complex heterogeneity of pathological changes occurring in Alzheimer's disease (AD), any therapeutic effort absolutely requires a multi-targeted approach, because attempts addressing only a single event may result ineffective. Palmitoylethanolamide (PEA), a naturally occurring lipid amide between palmitic acid and ethanolamine, seems to be a compound able to fulfill the criteria of a multi-factorial therapeutic approach. Here, we describe the anti-inflammatory and neuroprotective activities of systemic administration of PEA in adult male rats given intrahippocampal injection of beta amyloid 1-42 (Aß 1-42). Moreover, to investigate the molecular mechanisms responsible for the effects induced by PEA, we co-administered PEA with the GW6471, an antagonist of peroxisome proliferator-activated receptor-α (PPAR-α). We found that Aß 1-42 infusion results in severe changes of biochemical markers related to reactive gliosis, amyloidogenesis, and tau protein hyperphosphorylation. Interestingly, PEA was able to restore the Aß 1-42-induced alterations through PPAR-α involvement. In addition, results from the Morris water maze task highlighted a mild cognitive deficit during the reversal learning phase of the behavioral study. Similarly to the biochemical data, also mnestic deficits were reduced by PEA treatment. These data disclose novel findings about the therapeutic potential of PEA, and suggest novel strategies that hopefully could have the potential not just to alleviate the symptoms but also to modify disease progression.

RESUMO

OBJECTIVE: To investigate the effects of a physiotherapy protocol on patients with pleural effusion. DESIGN: Randomized controlled trial. SETTING: University hospital. PARTICIPANTS: A total of 104 consecutive inpatients with a medical diagnosis of pleural effusion. INTERVENTION: Patients were randomly allocated to a control group receiving standard treatment (medical treatment and drainage) or an intervention group treated with physiotherapy added to standard treatment. The physiotherapy programme included deep breathing exercises, mobilizations and incentive spirometry. MAIN OUTCOME MEASURES: Spirometric predicted values and chest radiographs were measured before treatment and at discharge and the length of hospital stay was recorded. Assessors were blinded to the intervention. RESULTS: A comparative analysis showed a significant improvement of spirometric parameters in the intervention group; pre-to-post hospitalization predicted values showed significant changes in vital capacity (73.1 ± 12.6% to 72.13 ± 13.7 %, P<0.001 ), forced expiratory volume in first second (72.13 ± 13.7% to 78.98 ± 16.9%, P<0.001) and forced expiratory flow at 25-75 % (64.8 ± 35.1% to 76.78 ± 35.3%, P=0.198) compared to the control group that showed no significant changes across treatment. The radiographic findings showed better scores on the affected side of the thorax at discharge in the physiotherapy group. Length of hospital stay was also significantly (P=0.014) shorter in the intervention group (26.7 ± 8.8 days) compared to the control group (38.6 ± 10.7 days). CONCLUSIONS: A physiotherapy programme added to standard treatment improves the spirometric parameters and the radiological findings and reduces the hospital stay in patients with a pleural effusion.

RESUMO

BACKGROUNDS AND AIMS: To examine the contribution of patient body mass index to functional status, physical independence and emotional distress in various age groups (third and fourth age) of female hip-fracture patients. METHODS: A sample of 123 older females (>65 years) admitted in a major regional hospital with a diagnosis of hip fracture participated in this cross-sectional study. The outcome measures used in this study were body mass index (BMI), the Modified Barthel Index, the Goldberg General Health Questionnaire, the Tinetti Mobility Test and a survey collecting data from participants 24-72 h after admission. For our analysis, patients were divided into two groups according to their age: <80 years (third age) and >81 years (fourth age). In addition, three groups were made according to patients' body mass index <24 h prior to surgery: a normal weight group, an overweight group and an obese group. An ANCOVA was performed with age group as a between-subjects variable (third age, fourth age) and gender, educational level, marital status, type of fracture, type of surgery, presence of other fractures and BMI as covariates. RESULTS: Patients in the third-age group obtained significantly higher values in the Barthel Index (P = 0.040) and the Tinetti Mobility Test (P = 0.001) and lower values in the Goldberg General Health Questionnaire (P = 0.035) compared to the fourth-age group. When BMI was considered, significance was maintained only in the Tinetti Mobility Test. CONCLUSIONS: The BMI could be a relevant mediator of the relationship between functional decline and the aging process in the transition between third to fourth age in females.

RESUMO

PURPOSE: The aim of this study was to evaluate the results of a conservative intervention in infants with plagiocephaly according to their specific clinical profile. METHODS: Prospective clinical trial in which 104 infants with plagiocephaly accompanied or not by congenital or positional torticollis were referred to Early Care and Monitoring Unit (USAT) of San Cecilio Hospital in Granada, between 2009 and 2012. All the infants, grouped into three categories of severity, were included in the physiotherapy protocol until adequate craniofacial morphology and motor development were achieved. The study included an assessment of parents and infants. Parents were assessed with a questionnaire about the mother's medical history and birth-related issues. The assessment of infants included anthropometric measures, a positional assessment, the observation of the head, the assessment of severity, and motor development. RESULTS: Birth characteristics were similar in the total sample but showed different clinical profiles according to treatment aspects. More specifically, infants with severe plagiocephaly were referred to treatment later and spent more time in treatment; use of an orthotic helmet was also more prevalent in this category. There were also significant differences (P < 0.05) in the acquisition of specific gross motor skills depending on the severity of plagiocephaly. CONCLUSION: The findings suggest that the physiotherapy protocol presented is effective to correct plagiocephaly. Severity of plagiocephaly is a marker that should be taken into account when designing actions aimed at improving gross motor skill development.

RESUMO

OBJECTIVE: To compare the effectiveness of proprioceptive neuromuscular facilitation combined with exercise, classic stretching physiotherapy intervention, and educational intervention at improving patient function and pain in patients with patellofemoral pain syndrome. DESIGN: Randomized, controlled, blind trial over four months. SETTING: Urban population, Spain. PARTICIPANTS: Patients undergoing primary care for retropatellar pain. INTERVENTION: Subjects were allocated on three different treatment options: a proprioceptive neuromuscular facilitation and aerobic exercise group, a classic stretching group, and a control treatment were applied over four months under the supervision of a physiotherapist. MAIN OUTCOME: Knee Society Score, pain reported (Visual analogue scale) and knee range of motion. Assessments were completed at baseline and after four months. RESULTS: 74 patients were enrolled in the study and distributed between groups. Both the proprioceptive neuromuscular facilitation and classic stretching group showed significant changes in all variables after four months intervention (p < 0.001). The difference in mean Kujala knee score changes between groups (classic stretching group vs. proprioceptive neuromuscular facilitation group vs. control group) at four months was -24.05 (95% confidence interval (CI) -30.19, -17.90), p ≤ 0.001; vs. -39.03 (95% confidence interval (CI) -42.5, -35.5), p ≤ 0.001; vs. -0.238 (95% confidence interval (CI) -1.2, 0.726), p = 0.621, respectively. CONCLUSIONS: A proprioceptive neuromuscular facilitation intervention protocol combined with aerobic exercise showed a better outcome than a classic stretching protocol after four months.

RESUMO

Recent studies show an alarming increase in levels of overweight and obesity among children and adolescents. The main objectives of this research were the following: (i) to carry out an anthropometric evaluation of the nutritional status and body composition of school children in the city and province of Granada; (ii) to compare the nutritional status of this population sample with national and international reference standards. The results obtained in this study showed that the general prevalence of overweight in both sexes was 22.03% and that 9.12% of the children were obese. Statistically significant differences were found between the variable, weight for age and sex (p < 0.05) and the variable, height for age and sex (p < 0.05). Regarding the body mass index, no statistically significant differences were found for the variable, sex (p = 0.182). This contrasted with the variable, age, which did show statistically significant differences (p < 0.05). As a conclusion, the results of our study highlighted the fact that these anthropometric values were much higher than national and international reference standards.

RESUMO

We previously reported impaired cholesterol biosynthesis in rodent Huntington Disease (HD) models and HD patients' fibroblasts and post mortem brains. We also found that plasma levels of 24S-hydroxycholesterol (24OHC), the brain specific elimination product of cholesterol considered a marker of brain cholesterol turnover, were significantly reduced in HD patients at any disease stage. In the present study we analysed by mass spectrometry the fasting plasma levels of cholesterol, its biosynthetic precursors lanosterol and lathosterol, of the whole-body elimination products 27-hydroxycholesterol and of brain 24OHC in a cohort of premanifest and HD patients at different disease stages. We found that the cholesterol precursors lanosterol and lathosterol (both index of whole body cholesterol synthesis), the levels of the bile acid precursor 27-hydroxycholesterol, and of the brain specific 24OHC, were all significantly reduced in manifest HD patients, suggesting that whole-body and brain cholesterol homeostasis are both impaired in HD.

RESUMO

90K/MAC-2BP glycoprotein is a serum tumour marker, member of the scavenger receptor cysteine rich (SRCR) protein superfamily, involved in different immunological mechanisms. In the present study, we determined 90K serum levels by a sandwich enzyme immunoassay using the same monoclonal antibody in 11 chronic active hepatitis (CAH), 48 liver cirrhosis and 36 hepatocellular carcinoma (HCC). In comparison, the same samples were also tested for AFP. According to a cut-off point of 14 micrograms/mL for the 90K, established as 100% of specificity in 50 controls, we observed increasing positivities from CAH to cirrhosis and then to HCC (27%, 50% and 78%, respectively). In cirrhotic patients 90K levels were associated with the presence of anti-HCV antibodies, but not with the degree of liver compromise. Finally, 90K sensitivity was higher than AIFP in all groups of hepatic patients. However, further investigations are needed before proposing 90K as a clinical useful tumour marker in the progression from cirrhosis to HCC.

RESUMO

Specific IgG and IgM antibodies to Chlamydia pneumoniae were evaluated by microimmunofluorescence test in a group of healthy subjects (age 0-18 years). Antibody titers (IgG) > or = 1:16 were found in 9.7% of the age group 0-1 years, in 5.3% of the group of 2-3 years and rose to 19% in children of the group 4-6 years. The seroprevalence was 11% and 17.1% in the group 7-12 years and 13-15 years, respectively. In the last group of 16-18 years the seroprevalence was 9.1%. The overall seroprevalence was 11.8% and C. pneumoniae infection is acquired before school age. In addition, in our pediatric patients it seems that C. pneumoniae does not play an important pathogenic role, being responsible for only 1.6% of the acute lower respiratory infections. The factors that may account for these findings are discussed.

RESUMO

Discussions of the ethics involved in allocating scarce resources often proceed without a grounding in factual experience. This study explored whether there was statistical evidence to support the use of set age limits in patient selection criteria for heart transplantation. Many transplant teams have selection criteria that include age limits, excluding patients more than 60 or 65 years of age from being considered as transplant candidates. The hypothesis was made that patients in the age bracket of 60-69 should have a comparable success rate with transplantation to that of younger recipients when selected by using the same medical and psychiatric criteria. Based on their clinical observations, the authors postulated that the elderly would report better quality of life postoperatively than younger control subjects.

RESUMO

The effective treatment of refractory allograft rejection with murine antihuman monoclonal antibody muromonab-CD3 (OKT3) and of patients with renal dysfunction has led to its use as induction therapy. The optimal protocol for OKT3 prophylaxis remains to be established. We compared 59 patients consecutively transplanted with the total orthotopic technique between 1/92 and 5/94. The first 21 patients were treated with OKT3 for 14 days, the next 19 for 10 days, and the last 19 for 7 days. Patients operated with different surgical techniques or other induction treatment were excluded. We compared length of stay (total and ICU), time to first rejection, rejection incidence and infection incidence (cytomegalovirus separately), and survival. Preoperative characteristics were similar except for significantly younger age in the 10-day group (p = 0.04). Preoperative hemodynamic parameters were similar except for a significantly higher left-ventricular ejection fraction (21%) in the 7-day group. Length of stays in the ICU and hospital were similar for the three groups (p = NS). Freedom from cellular rejection was lower with the 7 days course (p = 0.02), but freedom from humoral rejection was slightly higher (p = 0.11). However, patients in the 7-day group required treatment for rejection less frequently than patients in the other two groups (95% untreated at 2 months vs. 43% in the 14-day and 53% in the 10-day group; p = 0.002). There were no differences in incidence of infections, including cytomegalovirus. Survival was similar between the groups. There was one death in the 14-day and 1 in the 10-day group, both due to rejection. In conclusion, OKT3 therapy can be reduced safely to 7 days with a higher overall incidence of rejection but no increased necessity to treat for rejection, and no difference in infection incidence.

RESUMO

A 38-year-old man with a recent history of travel in India and unprotected sexual intercourse with Indian women, was admitted with painful enlarged lymphnodes predominantly in the right inguinal area. Diagnosis of lymphogranuloma venereum was made by means of a positive immunofluorescence test (Total Ig titer of 1:512) and a positive detection of chlamydial antigens by ELISA in a semen sample. He was successfully treated with ciprofloxacin. This observation emphasizes the relevance of infection due to C. trachomatis serotypes L1-L3 that may be acquired during travel in developing countries.
