Effectiveness of communicative and educative strategies in chronic low back pain patients: A systematic review
Objective: To investigate the effectiveness of communicative and educative strategies on 1) patient's low back pain awareness/knowledge, 2) maladaptive behavior modification and 3) compliance with exercise in patients with chronic low back pain. Methods: A systematic review was conducted. Searches were performed on 13 databases. Only randomized controlled trials enrolling patients 65 18 years of age were included. Risk of bias was assessed with the Cochrane Collaboration's tool and interrater agreement between authors for full-texts selection was evaluated with Cohen's Kappa. No meta-analysis was performed and qualitative analysis was conducted. Results: 24 randomized controlled trials which intervention included communicative and educative strategies were selected. Most of the studies were judged as low risk of bias and Cohen's Kappa was excellent ( = 0.822). Interventions addressed were cognitive behavioral therapy as unique treatment or combined with other treatments (multimodal interventions), coaching, mindfulness, pain science education, self-management, graded activity and graded exposure. Conclusions, practice implication: Patient's low back pain awareness/knowledge is still a grey area of literature. Pain science education, graded exposure and multimodal interventions are the most effective for behavior modification and compliance with exercise with benefits also in the long-term, while self-management, graded activity and coaching provide only short-term or no benefits
Sleep/wake rhythm modifications in the Italian population during SARS-CoV2 pandemic: a web-based cross-sectional survey.
Abstract. â OBJECTIVE: The study aims to
investigate in a representative sample of the
Italian population whether the SARS-CoV2 pandemic and the subsequent home isolation had
repercussion on the daily sleep/wake cycling
and habits.
MATERIALS AND METHODS: A web-based
cross-sectional survey consisted of various multiple-choice questions concerning demographic characteristics, sleep habits, and sleep-related problems was broadcast through mainstream social-media. Individuals were randomly allowed to participate from April 29th to May
17th, namely 50 days after the lockdown imposition and the day before its abrogation.
RESULTS: 58.84% of respondents experienced a change in their sleep habits. 71% of
those whose sleep changed showed a delayed
sleep pattern. Overall, a two-fold risk of delayed
sleep pattern without any change in total sleep
time emerged during the investigation period.
Females emerged almost 2 times more likely
to modify their sleep habits than males. Youths
were also more likely to experience modifications than old people, who conversely appeared
protected. A significant improvement in daytime
sleepiness occurred during the home isolation
which additionally correlated with delayed bedtime and less sleep time.
CONCLUSIONS: A high rate of change in
sleep habits, especially among youths and females, occurred in Italian population during the
home isolation to limit the SARS-CoV2 pandemic. Moreover, self-reported daytime sleepiness
decreased in severity
Rule-based Programming for Building Expert Systems: a Comparison in the Microbiological Data Validation and Surveillance Domain
Abstract In this work, we compare three rule-based programming tools used for building an expert system for microbiological laboratory data validation and bacteria infections monitoring. The first prototype of the system was implemented in KAPPA-PC. We report on the implementation and performance by comparing KAPPA-PC with two other more recent tools, namely JESS and ILOG JRULES. In order to test each tool we realized three simple test applications capable to perform some tasks that are peculiar of our expert system
Prevalence and incidence of low back pain among runners: A systematic review
Background: Running is one of the most popular sports worldwide. Despite low back pain (LBP) represents the most common musculoskeletal disorder in population and in sports, there is currently sparse evidence about prevalence, incidence and risk factors for LBP among runners. The aims of this systematic review were to investigate among runners: prevalence and incidence of LBP and specific risk factors for the onset of LBP. Methods: A systematic review has been conducted according to the guidelines of the PRISMA statement. The research was conducted in the following databases from their inception to 31st of July 2019: PubMed; CINAHL; Google Scholar; Ovid; PsycINFO; PSYNDEX; Embase; SPORTDiscus; Scientific Electronic Library Online; Cochrane Library and Web of Science. The checklists of The Joanna Briggs Institute Critical Appraisal tools were used to investigate the risk of bias of the included studies. Results: Nineteen studies were included and the interrater agreement for full-text selection was good (K = 0.78; 0.61-0.80 IC 95%). Overall, low values of prevalence (0.7-20.2%) and incidence (0.3-22%) of LBP among runners were reported. Most reported risk factors were: running for more than 6 years; body mass index > 24; higher physical height; not performing traditional aerobics activity weekly; restricted range of motion of hip flexion; difference between leg-length; poor hamstrings and back flexibility. Conclusions: Prevalence and incidence of LBP among runners are low compared to the others running related injuries and to general, or specific population of athletes. View the low level of incidence and prevalence of LBP, running could be interpreted as a protective factor against the onset of LBP. Systematic review registration: PROSPERO CRD42018102001
Gnomoniopsis castanea is the main agent of chestnut nut rot in Switzerland
Nuts of sweet chestnut have been an important food source for the alpine population in Switzerland since the Middle Ages and are still valued today for the preparation of traditional food commodities. Nut quality is reduced by insect damage and by various pathogenic fungi. In the last few years, producers and consumers perceived an increase of brown nut rot; while the nut rot agent Gnomoniopsis castanea was reported locally in southern Switzerland, its presence has not been investigated over large areas until now. This study assessed the incidence of brown nut rot and identified the causal agent present in Switzerland. Fully ripened nuts were collected from the main sweet chestnut growing areas of Switzerland. A filamentous fungus morphologically identified as G. castanea was isolated from 10 to 91% of the sampled nuts, despite only 3 to 21% of the sampled nuts showing brown rot symptoms. This fungus was isolated from symptomatic chestnuts as well as from apparently healthy chestnuts. Our results suggest a possible endophytic lifestyle in ripened nuts as well as in branches, leaves and unripe nuts as previously found. Species identity of 45 isolates was confirmed by EF-1alpha, beta-tubulin and ITS sequencing. Concatenation of ÎČ-tubulin and calmodulin sequences showed that several haplotypes were present at each sampling locality. No other nut rot pathogens could be isolated in this study, suggesting that G. castanea is the main causal agent of nut rot in Switzerland. The presence of this species is reported for the first time in a site in northern Switzerland. Further studies are needed to assess the influence of meteorological conditions and chestnut varieties on the incidence of G. castanea in order to provide prevention strategies for chestnut growers
Home-Based Exercise in Elderly Patients with Claudication and Chronic Kidney Disease Is Associated with Lower Progressive Renal Function Worsening: A 5-Year Retrospective Study
This observational study aimed to monitor the 5-year trends of kidney function in patients with peripheral artery disease (PAD) and concomitant chronic kidney disease (CKD) enrolled or not enrolled into a rehabilitative exercise program. Sixty-six patients (aged 72 ± 10, males n = 52) at KDOQI stages III-IV and PAD at Rutherfordâs stage I-III were included in the study, with a group (Exercise, EX; n = 32) receiving a 6-month structured pain-free home-based walking program and a group (Control, CO; n = 34) receiving walking advice and optimal nephrological care. Outcomes included kidney function measured through serum creatinine (sCr) and clinical outcomes, including the rate of advance of CKD stages and admission to dialysis, revascularizations, and hospitalizations. At baseline, the two groups were comparable for age, nephropathy, medications, comorbidities, and PAD severity. Patients in the EX group safely completed the exercise program. SCr values were slightly increased in EX (baseline: 2.35 ± 0.32; 5-year: 2.71 ± 0.39 mg/dL) and progressively worsened in CO (baseline: 2.30 ± 0.31; 5-year 4.22 ± 0.42 mg/dL), with a significant between-group difference (p = 0.002). The control group also showed a higher number of dialysis admissions (5 vs. 0, p = 0.025) and advancing CKD stage as well a higher risks for lower limb revascularization (hazard ratio: 2.59; 95%CI: 1.11â6.02; p = 0.027) and for all-cause hospitalization (hazard ratio: 1.77; 95%CI: 1.05â2.97; p = 0.031). PAD-CKD patients enrolled in a low-moderate intensity home-exercise program showed more favorable long-term trends in kidney function and clinical outcomes than patients with usual care. These preliminary observations need to be confirmed in randomized trials
Enrollment of Neonates in More Than One Clinical Trial
Because the highest rates of morbidity and mortality in neonates are seen in those born at 1 clinical trial. Neonatal units that have the infrastructure and resources to engage in research frequently face the question of whether it is permissible to enroll a neonate in >1 trial. This article examines the pertinent scientific, ethical, regulatory, and industry issues that should be taken into account when considering enrolling neonates in multiple clinical studies
Vascular calcification in chronic kidney disease [Le calcificazioni coronariche nell'insufficienza renale cronica]
Il rischio cardiovascolare nei pazienti con insufficienza renale cronica sia in fase conservativa (CKD) sia in fase sostitutiva (ESRD) eÌ maggiore rispetto alla popolazione generale poicheÌ ai fattori di rischio tradizionali si associano i potenti fattori di rischio che sono strettamente collegati con l'insufficienza renale.
Tra questi fattori, negli ultimi anni, notevole importanza eÌ stata posta alle calcificazioni dell'arterie coronariche (CAC) e alla loro progressione nel tempo sia nei pazienti con sia con CKD sia in ESRD.
Molteplici sono le metodiche attualmente accreditate per la valutazione della presenza, entitaÌ e progressione delle CAC.
In questa review si discuteraÌ l'importanza delle CAC per il rischio cardiovascolare dei pazienti nefropatici e si descriveranno le metodiche attualmentedisponibili per rilevarle e quantizzarle.Cardiovascular risk is higher in patients with chronic kidney disease (CKD) or with End-Stage Renal Disease (ESRD) than general population because in addition to the traditional cardiovascular (CV ) risk factors, CKD patients also have others non-traditional CV risk factors linked to CKD. Among these factors, presence and progression of coronary calcifications (CAC) are considered very important in CKD or ESRD patients in recent years. A number of noninvasive imaging methods are available to detect the presence, extent and progression of CAC. In this review, we discuss the importance of CAC as non-traditional CV risk factors in CKD patients and the noninvasive methods most frequently used to assess CAC
Assessment of the ochratoxin A production ability of Aspergillus tubingensis
Aspergillus tubingensis is a black Aspergillus frequently isolated from different agricultural products, including grapes. Conflicting results have been published in recent years about its ability to produce ochratoxin A (OTA), a potent nephrotoxic and carcinogenic mycotoxin. This study re-examined six A. tubingensis strains deposited in international culture collections for OTA production. OTA could not be detected in any A. tubingensis extract using HPLC coupled with a fluorescence detector (FLD), whereas it was easily detected in ochratoxigenic A. niger extracts used as positive control. The same outcome was obtained using LC-MS. The presence of other metabolites with retention times similar to the OTA signal in the A. tubingensis extracts or background noise of the growth media may be reasons for the misinterpretation of the chromatograms obtained by HPLC-FLD
The diagnostic value of Red Flags in thoracolumbar pain: a systematic review
Purpose: Red Flags (RFs) are signs and symptoms related to the screening of serious underlying pathologies mimicking a musculoskeletal pain. The current literature wonders about the usefulness of RFs, due to high false-positive rates and low diagnostic accuracy. The aims of this systematic review are: (a) to identify and (b) to evaluate the most important RFs that could be found by a health care professional during the assessment of patients with low and upper back pain (named as thoracolumbar pain (TLP)) to screen serious pathologies. Materials and methods: A systematic review of the literature was conducted. Searches were performed on seven databases (Pubmed, Web of Science, Cochrane Library, Pedro, Scielo, CINAHL, and Google Scholar) between March 2019 and June 2020, using a search string which included synonyms of low back pain (LBP), chest pain (CP), differential diagnosis, RF, and serious disease. Only observational studies enrolling patients with LBP or CP were included. Risk of bias was assessed with the Newcastle Ottawa Scale and inter-rater agreement between authors for full-text selection was evaluated with Cohen\u2019s Kappa. Where possible the diagnostic accuracy was recorded for sensitivity (Sn), specificity (Sp), and positive/negative likelihood ratio (LR+/LR\u2013). Results: Forty full-texts were included. Most of the included observational studies were judged as low risk of bias, and Cohen\u2019s Kappa was good (=0.78). The identified RFs were: advanced age; neurological signs; history of trauma; malignancy; female gender; corticosteroids use; night pain; unintentional weight loss; bladder or bowel dysfunction; loss of anal sphincter tone; saddle anaesthesia; constant pain; recent infection; family or personal history of heart or pulmonary diseases; dyspnoea; fever; postprandial CP; typical reflux symptoms; haemoptysis; sweating; pain radiated to upper limbs; hypotension; retrosternal pain; exertional pain; diaphoresis; and tachycardia. The diagnostic accuracy of RFs as self-contained screening tool was low, while the combination of multiple RFs showed to increase the probability to identify serious pathologies. Conclusions: Despite the use of single RF should not be recommended for the screening process in clinical practice, the combination of multiple RFs to enhance diagnostic accuracy is promising. Moreover, the identified RFs could be a baseline to develop a screening tool for patients with TLP.Implications for rehabilitation Differential diagnosis and screening for referral are mandatory skills for each healthcare professional in direct access clinical settings, and should be the primary step for an appropriate management of a patient with signs and symptoms mimicking serious pathologies in thoracolumbar region. Clinical reasoning and decision-making processes are essential throughout all phases of a patient\u2019s pathway of care. By which, the use of single Red Flag (RF) as a self-contained screening tool should not be recommended. The combination of multiple RFs promises to increase diagnostic accuracy and could grow into an excellent screening tool for thoracolumbar pain
