RESUMO

BACKGROUND: There have been conflicting studies reporting on survival advantages between breast-conserving surgery with radiotherapy (BCS) in comparison with mastectomy. Our aim was to compare the efficacy of BCS and mastectomy in terms of overall survival (OS) comparing all past published studies. METHODS: We performed a comprehensive review of literature through October 2021 in PubMed, Scopus, and EMBASE. The studies included were randomized controlled trials (RCTs) and cohorts that compare BCS versus mastectomy. We excluded studies that included male sex, stage 0, distant metastasis at diagnosis, bilateral synchronous cancer, neoadjuvant radiation/chemotherapy, and articles with incomplete data. We performed a meta-analysis following the random-effect model with the inverse variance method. RESULTS: From 18,997 publications, a total of 30 studies were included in the final analysis: 6 studies were randomized trials, and 24 were retrospective cohorts. A total of 1,802,128 patients with a follow-up ranging from 4 to 20 years were included, and 1,075,563 and 744,565 underwent BCS and mastectomy, respectively. Among the population, BCS is associated with improved OS compared with mastectomy [relative risk (RR) 0.64, 95% confidence interval (CI) 0.55-0.74]. This effect was similar when analysis was performed in cohorts and multi-institutional databases (RR 0.57, 95% CI 0.49-0.67). Furthermore, the benefit of BCS was stronger in patients who had less than 10 years of follow-up (RR 0.54, 95% CI 0.46-0.64). CONCLUSIONS: Patients who underwent BCS had better OS compared with mastectomy. Such results depicting survival advantage, especially using such a large sample of patients, may need to be included in the shared surgical decision making when discussing breast cancer treatment with patients.

RESUMO

Plant tissue in vitro culture is increasingly used in agriculture to improve crop production, nutritional quality, and commercial value. In plant virology, the technique is used as sanitation protocol to produce virus-free plants. Sanitized (S) artichokes show increased vigour compared to their non-sanitized (NS) counterparts, because viral infections lead to a decline of growth and development. To investigate mechanisms that control the complex traits related to morphology, growth, and yield in S artichokes compared to NS plants, RNAseq analysis and phenotyping by imaging were used. The role of peroxidases (POD) was also investigated to understand their involvement in sanitized plant development. Results showed that virus infection affected regulation of cell cycle, gene expression and signal transduction modulating cellular response to stimulus/stress. Moreover, primary metabolism and photosynthesis were also influenced, contributing to explain the main morphological differences observed between S and NS artichokes. Sanitized artichokes are also characterized by higher POD activity, probably associated with increased plant growth, rather than strengthening of cell walls. Overall, results show that the differences in development of S artichokes may be derived from the in vitro culture stressor, as well as through pathogen elimination, which, in turn, improve qualitative and quantitative artichoke production.

RESUMO

Aim: We performed a systematic review and meta-analysis to identify the prevalence of small intestinal bacterial overgrowth (SIBO) in patients with gastroparesis. Background: Several studies have suggested an association between SIBO and gastroparesis, which is characterized by delayed gastric emptying in the absence of mechanical obstruction. Methods: A comprehensive search was performed using MEDLINE, EMBASE, Scopus and Cochrane Central Register of Controlled Trials (CENTRAL) through January, 2022 for randomized controlled trials and observational studies reporting the prevalence of SIBO in gastroparesis. Pooled prevalence was estimated using a random effects model. Heterogeneity was assessed by using the inconsistency index (I2). Results: Among the 976 articles identified, 43 studies were selected for full text review. Six studies, with 385 patients, were deemed eligible for inclusion, with a perfect agreement between investigators (kappa=1.0). Overall, 379 patients were diagnosed with gastroparesis by gastric emptying scintigraphy and six were diagnosed with a wireless motility capsule. The pooled prevalence of SIBO was 41% (95% confidence interval 0.23-0.58). SIBO was diagnosed using jejunal aspirate cultures (N=15, 8.4%), lactulose breath test (N=80, 44.7%), glucose breath test (N=30, 16.8%), D-xylose breath test (N=52, 29.1%), and hydrogen breath test (N=2, 1.1%). Heterogeneity was significant and noted to be high at 91%. Only one study reported SIBO diagnosis in controls, therefore no pooled odds ratio was calculated. Conclusion: SIBO was present in almost half of the patients with gastroparesis. Future studies should examine and identify the association between SIBO and gastroparesis.

RESUMO

OBJECTIVE: To document racial disparity in biomarker concentrations in maternal/fetal plasma and amniotic fluid between African Americans and European Americans with spontaneous preterm birth (PTB; cases) and normal term birth (controls), and their contribution to distinct pathophysiological pathways of PTB. DESIGN: Nested case-control study. SETTING: The Perinatal Research Center, Nashville, Tennessee, USA. SAMPLE: Maternal and fetal plasma and amniotic fluid samples were collected from 105 cases (59 African American and 46 European American) and 86 controls (40 African American and 46 European American). METHODS: Thirty-six biomarkers were analysed using the protein microarray approach. MAIN OUTCOME MEASURES: Differences in biomarker concentrations between cases and controls of different races in maternal, fetal and intra-amniotic compartments, and the risk of PTB. Dysregulated biomarker-induced PTB pathways associated with PTB in each race were determined using ingenuity pathway analysis (IPA). RESULTS: Racial disparity was observed in biomarker concentrations in each compartment between cases and controls: amniotic fluid, IL8 and MIP1α differed between case and controls in European Americans, whereas ANGPT2, Eotaxin, ICAM-1, IL-1ß, IL1RA, RANTES and TNFα differed between case and controls in African Americans. In both races the FAS ligand, MCP-3 and TNFR-I differed between cases and controls. For fetal plasma, ANGPT2, Eotaxin, FGF basic, ICAM-1, IGF-I, IL10, IL-1ß, IL2, IP10 KGF, MCP-3, MIP1α, PDGF-BB, TGFα, TGFß1, TIMP1, TNFα, TNFR-I, TNFR-II and VEGF differed between cases and controls in European Americans, whereas only MMP7 differed between cases and controls in African Americans. IL-8 differed between cases and controls in both races. For maternal plasma, IL1RA, MMP7 and VEGF differed between cases and controls in European Americans, whereas ANGPT2, FGF basic, IL-1ß, IL5, IL6R, KGF, MCP-3, MIP1α, TIMP1 and TNFα differed between cases and controls in African Americans. ANG, IL8 and TNFR-I differed between cases and controls in both races. CONCLUSIONS: We conclude that: (1) biomarker concentrations in maternal, fetal and intra-amniotic compartments differ between cases and controls; (2) there is racial disparity in the biomarker profile in each of the compartments; (3) substantial numbers of dysregulated fetal plasma biomarkers contribute to PTB in European Americans, whereas maternal plasma biomarkers contribute to PTB in African Americans; and (4) both inflammation and haematological functions are associated with PTB in European Americans, but maternal proinflammatory changes dominate PTB in African Americans. Biomarker analyses document racial disparity and the distinct pathophysiological contributions from different compartments that can determine pregnancy outcome.

RESUMO

Biospeckle is a technique whose purpose is to observe and study the underlying activity of some material. It has its roots in optical physics, and its first step is an image acquisition process that produces a video sequence of the reflection of a laser. The video content can be analyzed to have an interpretation of the activity of the observed material. The literature on this subject presents several different measures for analyzing the video sequence. Three of the most popular measures are the generalized difference (GD), the weighted generalized difference (WGD), and Fujii's method. These measures have drawbacks such as high computation time or limited visual quality of the results. In this paper, we propose (i) an alternative O(n) algorithm for the computation of the GD, (ii) an alternative measure based on the GD, (iii) an alternative measure based on the WGD, and (iv) a generalized definition of the Fujii's method with better visual quality. We discuss the similarities between the new measures and the existent ones, showing when they are applicable. We prove the gain in time computation. The proposed measures will help researchers to gain time during their research and to be able to develop faster tools based on biospeckle application.

RESUMO

The objectives of the study were to: report three more cases of cochlear implantation (CI) in patients affected by superficial hemosiderosis of the central nervous system (SH-CNS); assess whether CI may be a viable option in this disease. The study was conducted in a tertiary referral center. Pre-operative and post-operative clinical notes of three patients with SH-CNS were reviewed. Two out of three cases showed very good results with CI in sentence perception in noise over 90%. For the other case, hearing performance was very low. He showed only disyllabic word identification abilities in a closed set (40%). Cochlear implantation may be a viable option for patients with severe to profound sensorineural hearing loss due to SH-CNS. In these cases, an adequate pre-operative counseling, explaining the possibility of poor post-operative results and/or the worsening of the outcomes in the following years, is important.

RESUMO

AIM: The main aim of the study was to investigate the efficacy of a "take-in- charge" model of advanced stage melanoma patients by a multidisciplinary team and highlight the psychological patterns of the disease. METHODS: The study sample involved 44 patients, 27 females and 17 males, who were given a "Questionnaire on Health Status SF-12" which provides two synthetic indexes, one related to physical health PCS-12, and the other to mental health MCS-12. The statistical data was collected through a preliminary analysis of principal components P.C. A., carried out with SPSS software. RESULTS: Comparing the scores obtained by the PCS and MCS indexes, the mean score is low: 6.52 out of 10 for PCS and 3.23 out of 10 for MCS. At first consultation, there is evidence which supports patients' need for psycho-oncological support. By dividing the sample patients into two subgroups, cutaneous melanoma and visceral melanoma, it should be noted that the first group obtained a mean of 4.75 for PCS and 3.77 for MCS and the second group 7.53 for PCS and 2.92 for MCS respectively. Therefore, the results show, at first consultation, a more complex situation for patients with cutaneous melanoma. CONCLUSION: The results of the study highlight the need to supply some form of psycho-oncological support to help patients while they adapt to the disease. Furthermore, different problems and different coping styles also emerged depending on whether the patient has cutaneous or visceral melanoma. The study therefore demonstrates the need to take into account such variables when devising a personal care system centered on the patient.

RESUMO

Cardiovascular disease (CVD) has become one of the commonest causes of comorbidity and mortality among People living with human immunodeficiency virus (HIV) (PLWH) on antiretroviral therapy (ART). Nearly 50% of PLWH are likely to have an increased risk of developing CVD, including coronary heart disease, cerebrovascular disease, peripheral artery disease and aortic atherosclerosis. Aside from the common risk factors, HIV infection itself and side effects of antiretroviral therapy contribute to the pathophysiology of this entity. Potential non-pharmacological therapies are currently being tested worldwide for this purpose, including eating patterns such as Intermittent fasting (IF). IF is a widespread practice gaining high level of interest in the scientific community due to its potential benefits such as improvement in serum lipids and lipoproteins, blood pressure (BP), platelet-derived growth factor AB, systemic inflammation, and carotid artery intima-media thickness among others cardiovascular benefits. This review will focus on exploring the potential role of intermittent fasting as a non-pharmacological and cost-effective strategy in decreasing the burden of cardiovascular diseases among HIV patients on ART due to its intrinsic properties improving the main cardiovascular risk factors and modulating inflammatory pathways related to endothelial dysfunction, lipid peroxidation and aging. Intermittent fasting regimens need to be tested in clinical trials as an important, cost-effective, and revolutionary coadjutant of ART in the fight against the increased prevalence of cardiovascular disease in PLWH.

RESUMO

BACKGROUND: The cause of end-organ damage and acute respiratory distress syndrome (ARDS) in coronavirus disease 2019 (COVID-19) patients is postulated to be connected to the uncontrolled increase of pro-inflammatory cytokines. The upregulation of many cytokines is dependent on signaling through the Janus kinase 1 (JAK-1) and JAK-2 pathways. Ruxolitinib, a JAK-1 and JAK-2 inhibitor, is documented to have potent anti-inflammatory activity by targeting several cytokines and growth factors with proposed efficacy in the cytokine storm observed in severe COVID-19 patients; therefore, this study examines the efficacy and tolerability of ruxolitinib for adult COVID-19 patients. MATERIALS AND METHODS: This review was conducted using preferred reporting items for aystematic reviews and meta-analyses (PRISMA) methodology. Six reviewers analyzed 1,120 results. Seven studies were selected and validated. A quantitative meta-analysis was further performed to evaluate clinical improvement at day 28, mortality at day 28, and oxygen requirements comparing treatment and standard of care groups. RESULTS: 168 individuals were involved in the studies selected: 122 in cohort studies, 4 in case reports, and 41 in randomized controlled studies. The ruxolitinib group had a higher likelihood of clinical improvement by the 28th day of treatment when assessed with the standard of care (SOC) group (odds ratio [OR]: 1.48; 95% confidence interval [CI]: 0.53 - 4.16; P = 0.45; I² = 0%). The SOC group was at a higher risk of experiencing serious adverse events (OR: 0.17; 95% CI: 0.03 - 1.13; P = 0.07). Notably the SOC group had a higher likelihood of death (OR: 0.51; 95% CI: 0.11-2.29; P = 0.07; I² = 0%). CONCLUSION: Prior studies on ruxolitinib have demonstrated it is able to decrease inflammatory markers. In recent studies on COVID-19, treatment with ruxolitinib decreased the time on mechanical ventilation, hospitalization time, and the need for vasopressor support. Additionally, ruxolitinib showed decreased mortality and demonstrated improvement in lung congestion as evidenced by computerized tomography imaging. These findings warrant further clinical investigation into Ruxolitinib as a potential treatment approach for severe COVID-19.

RESUMO

Previous studies have described multiple nutritional deficiencies after bariatric surgery (BS). However, few studies have evaluated these deficiencies prior to BS, specifically in Latin America. This study aimed to determine the factors associated with nutritional deficiency biomarkers in candidates for BS in Peru. We included adults of both sexes, aged 18 to 59 years, admitted to a Peruvian clinic with a body mass index (BMI) ≥30 kg/m2; they were candidates for BS from 2017 to 2020. We considered the serum levels of hemoglobin and albumin (in tertiles) as the nutritional deficiency biomarkers. In order to assess the associated factors, we calculated crude (cPR) and adjusted prevalence ratios (aPR) with their respective 95% confidence intervals (95%CI). We analyzed 255 patients: 63.1% were males, with a mean age of 37.1 ± 10.3 years and mean hemoglobin and albumin values of 14.0 ± 1.5 g/dL and 4.6 ± 0.4 g/dL, respectively. We found that males (aPR = 1.86; 95%CI: 1.26-2.73; p = 0.002), participants between 30 and 49 (aPR = 2.02; 95%CI: 1.24-3.28; p = 0.004) or 50 years or more (aPR = 2.42; 95%CI: 1.35-4.35; p = 0.003), participants with a BMI ≥40 kg/m2 (aPR = 1.68; 95%CI: 1.09-2.60; p = 0.018), participants with impaired high-density lipoprotein levels (aPR = 1.43; 95%CI: 1.01-2.05; p = 0.049) and individuals in the high tertile of C-reactive protein (aPR = 6.94; 95%CI: 3.37-14.32; p < 0.003) had a higher probability of being in the lower tertile of albumin. In addition, we found that the male sex (aPR = 6.94; 95%CI: 3.37-14.32; p < 0.001) and elevated cholesterol levels (aPR = 0.71; 95%CI: 0.52-0.97; p = 0.034) were associated with the lowest hemoglobin tertile. In our setting, nutritional deficiency biomarkers were associated with sociodemographic, anthropometric and laboratory markers. The pre-bariatric surgery correction of nutritional deficiencies is essential, and can prevent major complications after surgery.

RESUMO

BACKGROUND: The high rate of transmission and infection of coronavirus disease 2019 (COVID-19) is a public health emergency of major epidemiological concern. No definitive treatments have been established, and vaccinations have only recently begun. We aim to review the efficacy and safety of Interferon Beta (IFN-ß) in patients who have a confirmed COVID-19 diagnosis. MATERIALS AND METHODS: A search from PubMed, Science Direct, Cochrane, and Clinicaltrials.gov databases were conducted from December 2019 to December 2020 to review the efficacy and safety of IFN-ß in adult patients with COVID-19 confirmed. We included randomized controlled trials, case reports, and experimental studies. Correspondences, letters, editorials, reviews, commentaries, case control, cross-sectional, and cohort studies that did not include any new clinical data were excluded. RESULTS: Of the 66 searched studies, 8 were included in our review. These studies demonstrated that although IFN-ß did not reduce the time to clinical response, there was an increase in discharge rate at day 14 and a decrease in mortality at day 28. The time to negative reverse transcription polymerase chain reaction (RT-PCR) was shown to be significantly shortened in patients receiving IFN-ß, along with a lower nasopharyngeal viral load. Further, patients receiving IFN-ß had a less significant rise in IL-6. IFN-ß was shown to decrease intensive care unit (ICU) admission rate, the requirement of invasive ventilation in severe cases, and improve the survival rate compared to control groups. There were no severe adverse events reported. Our review found that patients who received early treatment with IFN-ß experienced significantly reduced length of hospitalization, mortality, ICU admission, and mechanical ventilation. A greater chance of clinical improvement and improved imaging studies was noted in patients who received IFN-ß. There were no reported deaths associated with the addition of IFN-ß. Further randomized trials involving more significant sample sizes are needed to better understand the effect of IFN-ß on survival in COVID-19. CONCLUSION: This review identified encouraging data and outcomes of incorporating IFN-ß to treat COVID-19 patients. IFN-ß has been shown to decrease hospital stay's overall length and decrease the severity of respiratory symptoms when added to the standard of care. Also, in some studies, it has been demonstrated to reduce the length of ICU stay, enhance survival rate, and decrease the need for invasive mechanical ventilation. There were minor side effects reported (neuropsychiatric symptoms and hypersensitivity reaction). However, randomized clinical trials with a large sample size are needed to assess IFN-ß's benefit precisely.

RESUMO

BACKGROUND: Eosinophilic granulomatosis with polyangiitis and granulomatosis with polyangiitis show variable otorhinolaryngological involvement. Up to 14 per cent of granulomatosis with polyangiitis patients have subglottis involvement; little is known about the laryngeal involvement in eosinophilic granulomatosis with polyangiitis. METHOD: A literature review was conducted, together with a prospective cross-sectional analysis of 43 eosinophilic granulomatosis with polyangiitis patients. All patients underwent fibre-optic laryngoscopy with narrow-band imaging, and completed health-related questionnaires. RESULTS: The literature review showed only two cases of laryngeal involvement in eosinophilic granulomatosis with polyangiitis; in our cohort, no cases of subglottis stenosis were found, but local signs of laryngeal inflammation were present in 72 per cent of cases. Of the patients, 16.2 per cent had a pathological Reflux Finding Score (of 7 or higher). CONCLUSION: Laryngeal inflammation in eosinophilic granulomatosis with polyangiitis is frequent. It is possibly due more to local factors than to eosinophilic granulomatosis with polyangiitis itself. However, ENT evaluation is needed to rule out possible subglottis inflammation. These findings are in line with current literature and worthy of confirmation in larger cohorts.

RESUMO

OBJECTIVE: The objective of this study is to examine TNF-alpha and its soluble and membrane bound receptors in fetal membranes derived from blacks and whites in response to in vitro infectious stimulus, and the balance between TNF-alpha and the receptors. Fetal membranes collected from black and white women at term were maintained in an organ explant system and stimulated with lipopolysaccharide (LPS). TNF-alpha, soluble TNF receptors (sTNFR1 and sTNFR2) in culture media and membrane bound TNF receptors (TNFR1 and TNFR2) in tissue homogenates were measured. Molar ratio (TNF/sTNFR) was calculated between LPS stimulated and unstimulated (controls) cultures in both races. TNF-alpha was increased in both races after LPS stimulation and showed no difference between races (p=0.7). LPS decreased sTNFR1 in blacks, but increased in whites, showing a significant difference between races (p=0.001). In blacks sTNFR2 also decreased and increased in whites, but the results were not significant between races (p=0.4). Both TNFR1 and TNFR2 were increased in blacks after LPS stimulation whereas no such changes were seen in whites compared to controls that were also significant between races. After LPS stimulation TNF-alpha bioavailability was increased in blacks with a drop in soluble receptors and with an increase in membrane receptors. This was not evident in whites because in whites soluble receptors were increased with no change in membrane receptors. Our data demonstrated that LPS stimulation results in a molar ratio switch favoring TNF-alpha biofunction in blacks, but not in whites.

RESUMO

The aim of this study is to report our results in a group of prelingually deafened adults, who followed an oralist rehabilitation programme, and submitted to cochlear implant at our institution. We evaluated 30 prelingually deafened adult patients, 18 males and 12 females, median age 35 years, of a group of 36 prelingually deafened adult patients consecutively submitted to unilateral cochlear implantation at the ENT Unit of the University of Pisa. After implantation, patients achieved significant benefits in terms of speech perception skills, including the ability to have telephone conversations in some cases, quality of life and their own perception of disability. According to literature data, the results herein reported are quite variable but generally satisfactory. Procedures other than traditional speech perception measures should be used to evaluate the benefits of cochlear implant in such patients, to compressively evaluate the global benefits, not only in terms of speech perception, but also in terms of quality of life and daily life.

RESUMO

The altered metabolism observed in cancer cells generally consists in increased glucose uptake and glycolytic activity. This is associated with an overexpression of glucose transporter proteins (GLUTs), which facilitate glucose uptake across the plasma membrane and play a crucial role in the survival of cancer cells. Therefore GLUTs are considered as suitable targets for the treatment of cancer. Herein we review some of the most relevant GLUT inhibitors that have been recently developed as prospective anticancer agents.

RESUMO

BACKGROUND: The frequency with which a scientific article is cited by other studies is one way to measure its academic influence. METHODS: A comprehensive search was performed to identify journal articles in the otorhinolaryngology subject category of the 2013 Journal Citation Report Science Edition over the last 30 years (1985-2014). The 100 most cited articles were reviewed and basic information including the publication year, country of origin, source journal, article type and research field was collected. RESULTS: The 100 most cited articles were published in 15 of the 44 otorhinolaryngology journals. The number of citations per article ranged between 208 and 1559. The leading research field was otology and neurotology (n = 50), followed by rhinology (n = 23) and head and neck surgery (n = 11). Most papers originated in the USA (n = 64). CONCLUSION: The possibility of an article being cited is influenced by the publication language, country of origin and source journal.

RESUMO

A retrospective chart review was used for 31 patients with sudden, progressive or fluctuating sensorineural hearing loss (SHL) in the only hearing ear who had been consecutively evaluated at the ENT, Audiology and Phoniatrics Unit of the University of Pisa. The group of patients was evaluated with a complete history review, clinical evaluation, imaging exam (MRI, CT), audiologic tests (tone and speech audiometry, tympanometry, study of stapedial reflexes, ABR and otoacoustic emission) evaluation. In order to exclude genetic causes, patients were screened for CX 26 and CX30 mutations and for mitochondrial DNA mutation A1555G. Patients with sudden or rapidly progressive SHL in the only hearing ear were treated with osmotic diuretics and corticosteroids. In patients who did not respond to intravenous therapy we performed intratympanic injections of corticosteroid. Hearing aids were fitted when indicated and patients who developed severe to profound SHL were scheduled for cochlear implant surgery. The aim of this study is to report and discuss the epidemiology, aetiopathogenesis, therapy and clinical characteristic of patients affected by SHL in the only hearing hear and to discuss the issues related to the cochlear implant procedure in some of these patients, with regard to indications, choice of the ear to implant and results.

RESUMO

Age-related hearing loss (ARHL) has a multifactorial pathogenesis and it is an inevitable hearing impairment associated with reduction of communicative skills related to ageing. Increasing evidence has linked ARHL to more rapid progression of cognitive decline and incidental dementia. Many aspects of daily living of elderly people have been associated to hearing abilities, showing that hearing loss (HL) affects the quality of life, social relationships, motor skills, psychological aspects and function and morphology in specific brain areas. Epidemiological and clinical studies confirm the assumption of a relationship between these conditions. However, the mechanisms are still unclear and are reviewed herein. Long-term hearing deprivation of auditory inputs can impact cognitive performance by decreasing the quality of communication leading to social isolation and depression and facilitate dementia. On the contrary, the limited cognitive skills may reduce the cognitive resources available for auditory perception, increasing the effects of HL. In addition, hearing loss and cognitive decline may reflect a 'common cause' on the auditory pathway and brain. In fact, some pathogenetic factors are recongised in common microvascular disease factors such as diabetes, atherosclerosis and hypertension. Interdisciplinary efforts to investigate and address HL in the context of brain and cognitive ageing are needed. Surprisingly, few studies have been adressed on the effectiveness of hearing aids in changing the natural history of cognitive decline. Effective interventions with hearing aids or cochlear implant may improve social and emotional function, communication, cognitive function and positively impact quality of life. The aim of this review is to overview new insights on this challenging topic and provide new ideas for future research.

RESUMO

BACKGROUND: Patients with whiplash associated disorders (WAD) may present with physical and psychological symptoms which persist long after the initial onset of pain. Several studies have shown that therapeutic exercise for motor and sensorimotor control combined with manual therapy in a multimodal rehabilitation (MMR) program is effective at improving pain and disability in patients with neck disorders. To date, no studies have investigated which self-reported physical or psychological symptoms are predictive of response to this MMR program. AIM: To determine which baseline features can predict outcome following a 3-week MMR program in patients with WAD. DESIGN: Observational prospective cohort study. SETTING: Outpatient rehabilitation clinic. POPULATION: Thirty-seven patients aged >18 years with a diagnosis of WAD grade II or III. METHODS: The MMR program included manual therapy, motor control and sensorimotor control training according to the clinical impairments of each patient. Patients were assessed before and after treatment for their physical and psychological symptoms by means of self-reported questionnaires. Regression models were estimated with pain intensity, disability and post-traumatic stress symptoms (PTSS) as outcomes. RESULTS: After treatment, patients exhibited significant improvements in all evaluated outcomes (all P<0.01). Regression models accounting for 35% and 36% of the variance in pain intensity outcomes included average pain intensity over the previous week and pain catastrophizing as significant predictors. Disability and pain catastrophizing were predictors of changes in disability following the MMR program explaining 49% of the variance in the model. Furthermore, higher PTSS at baseline was a significant predictor of PTSS after treatment, explaining 55% of the variance in the model. CONCLUSION: Improved outcomes on pain intensity, disability and PTSS following a MMR program could be partially predicted based on the patient's initial presentation. CLINICAL REHABILITATION IMPACT: This knowledge may assist clinicians in predicting outcome following a MMR program inclusive of specific exercise therapy and manual therapy in patients with WAD.
