Therapeutic exercises in the clinical practice of Brazilian physical therapists in the management of rotator cuff tendinopathy: An online survey.

The objective of this study was to investigate how Brazilian physical therapists (PTs) use therapeutic exercises in the rehabilitation of individuals with rotator cuff (RC) tendinopathy. The study used an online survey with a mix of 62 open- and closed-ended questions divided into three sections: participant demographics, professional experience, and clinical practice in the rehabilitation of patients with RC tendinopathy. One hundred and fifty-nine Brazilian physical therapists completed the survey. Most of our sample recommended isometric exercises (69.9%) in the initial phase of rehabilitation and eccentric exercises (47.4%) in the advanced phase. However, there was a wide variability in determining the volume of exercises, particularly with isometric exercises. Most of our sample considered patient comfort and pain levels when adjusting exercise intensity, regardless of exercise type. The majority (48.40%) recommended weekly reassessment and modification of exercises. Additionally, despite pain being a key factor for discharge and the primary adverse effect of exercise, most of our sample would not discontinue exercises in case of pain during the early and late phases of rehabilitation. Despite the lack of consensus on some aspects, the clinical practice of our sample is in line with the current literature and practice in other countries. However, further research and implementation are crucial to enhance future rehabilitation outcomes, including exploring the exercise training volume, the safety and effectiveness of exercising with pain and identifying the optimal pain level for best results.

Rotator cuff isometric exercises in combination with scapular muscle strengthening and stretching in individuals with rotator cuff tendinopathy: A multiple-subject case report.

BACKGROUND AND PURPOSE: To assess the effects of a rehabilitation protocol of rotator cuff (RC) isometrics coupled with traditional shoulder exercises on patient-rated outcomes, muscle strength, and electromyographic activity in individuals with RC tendinopathy. METHODS: Eleven individuals (8 women and 3 men, 37.9 ± 5.6 years) with RC tendinopathy performed isometric RC exercises in combination with scapular muscle stretching and strengthening for 6 weeks. Treatment effects were assessed with patient-rated pain and shoulder function, isometric muscle strength, electromyographic activity during arm elevation and internal and external shoulder rotation, and pain during arm elevation before and at the end of the first session, and after 6 weeks of intervention. RESULTS: There were improvements in pain and shoulder function, increased isometric muscle strength for arm elevation and internal rotation, increased muscle activity of the infraspinatus and serratus anterior, and reduced pain during arm elevation after 6 weeks of intervention. DISCUSSION: This case report showed improvements on pain and function, increases on isometric strength of the shoulder and on electromyographic activity of the serratus anterior and infraspinatus muscles, as well as decreases on pain during arm elevation, after a 6-week intervention of RC isometric exercises associated with scapular muscle stretching and strengthening in patients with RC tendinopathy.

Bidirectional Violence in Intimate Relationships: A Systematic Review.

Intimate partner violence is a public health problem with significant consequences at different levels. Over the years, the literature has shown that most violence is not unidirectional and perpetrated by men against women but rather bidirectional, in which both couple elements may be victims, perpetrators, or both. In this systematic literature review, we aimed to systematize the empirical knowledge to assess the prevalence of bidirectional violence, the most reported types of violence, and the influence of sex and sexual orientation on this phenomenon. The search for this systematic review was conducted in four databases, and we included studies that showed the prevalence of bidirectional violence in samples aged over 18 years, in articles written in English or Portuguese, and published between 2012 and 2022. In the qualitative synthesis, 42 empirical studies were included. The results showed that bidirectional violence is the most common pattern of violence, with psychological violence being the most reported type of bidirectional violence; men and women reported bidirectional violence at similar rates, and homosexual couples reported higher percentages of bidirectional violence than heterosexual couples. These results contradict the patriarchalist view of violence that assigns the exclusivity role of the victim to women and of the perpetrator to men, demonstrating that violence occurs regardless of sex or sexual orientation. The practical implications and future directions at the level of public policies to give visibility to the phenomenon will be duly discussed.

Isometric versus isotonic exercise in individuals with rotator cuff tendinopathy-Effects on shoulder pain, functioning, muscle strength, and electromyographic activity: A protocol for randomized clinical trial.

INTRODUCTION: Rotator cuff tendinopathy is a common shoulder disorder in which the primary treatment is resistance exercises. Isometric exercises are being studied for lower limb tendinopathies but not for rotator cuff tendinopathy. This protocol for a randomized clinical trial aims to compare the effects of two types of exercise (isometric and isotonic) on shoulder pain, functioning, muscle strength, and electromyographic activity in individuals with rotator cuff tendinopathy. METHODS: Forty-six individuals (18 to 60 years old) with shoulder pain for more than three months and unilateral supraspinatus and/or infraspinatus tendinopathy will participate in this trial. Individuals will be randomized into two exercise groups: isometric or isotonic. The following outcomes will be evaluated before and after the first session and after six weeks of intervention: shoulder pain and functioning; isometric strength of shoulder elevation and lateral and medial rotation; and electromyographic activity of medial deltoid, infraspinatus, serratus anterior, and lower trapezius. Groups will perform stretching and strengthening of periscapular muscles. The isometric group will perform three sets of 32 s, at 70% of maximal isometric strength. The isotonic group will perform concentric and eccentric exercises (2 s for each phase) in three sets of eight repetitions at a load of eight repetition maximum. The total time under tension of 96 s will be equal for both groups, and load will be adjusted in weeks three and five of the protocol. Treatment effect between groups will be analyzed using linear mixed model. TRIAL REGISTRATION: Trial registration number: Universal Trial Number (UTN) code U1111-1284-7528 and Brazilian Clinical Trials Registry platform-RBR-3pvdvfk.

Optimization of high-throughput 16S rRNA gene amplicon sequencing: an assessment of PCR pooling, mastermix use and contamination.

16S rRNA gene sequencing is widely used to characterize human and environmental microbiomes. Sequencing at scale facilitates better powered studies but is limited by cost and time. We identified two areas in our 16S rRNA gene library preparation protocol where modifications could provide efficiency gains, including (1) pooling of multiple PCR amplifications per sample to reduce PCR drift and (2) manual preparation of mastermix to reduce liquid handling. Using nasal samples from healthy human participants and a serially diluted mock microbial community, we compared alpha and beta diversity, and compositional abundance where the PCR amplification was conducted in triplicate, duplicate or as a single reaction, and where manually prepared or premixed mastermix was used. One hundred and fifty-eight 16S rRNA gene sequencing libraries were prepared, including a replicate experiment. Comparing PCR pooling strategies, we found no significant difference in high-quality read counts and alpha diversity, and beta diversity by Bray-Curtis index clustered by replicate on principal coordinate analysis (PCoA) and non-metric dimensional scaling (NMDS) analysis. Choice of mastermix had no significant impact on high-quality read and alpha diversity, and beta diversity by Bray-Curtis index clustered by replicate in PCoA and NMDS analysis. Importantly, we observed contamination and variability of rare species (<0.01 %) across replicate experiments; the majority of contaminants were accounted for by removal of species present at <0.1 %, or were linked to reagents (including a primer stock). We demonstrate no requirement for pooling of PCR amplifications or manual preparation of PCR mastermix, resulting in a more efficient 16S rRNA gene PCR protocol.

Infective endocarditis risk in patients with bicuspid aortic valve: Systematic review and meta-analysis.

Background: Antibiotic prophylaxis in bicuspid aortic valve patients is currently a matter of debate. Although it is no longer recommended by international guidelines, some studies indicate a high risk of infective endocarditis. We aim to evaluate the risk of native valve infective endocarditis in bicuspid aortic valve patients and compare to individuals with tricuspid aortic valve. Methods: Study search of longitudinal studies regarding infective endocarditis incidence in bicuspid aortic valve patients (compared with tricuspid aortic valve/overall population) was conducted through OVID in the following electronic databases: MEDLINE, CENTRAL, EMBASE; from inception until October 2020. The outcomes of interest were the incidence rate and relative risk of infective endocarditis. The relative risk and incidence rate (number of cases for each 10 000 persons-year) with their 95 % confidence intervals (95 %CI) were estimated using a random effects model meta-analysis. The study protocol was registered at PROSPERO CRD42020218639. Results: Eight cohort studies were selected, with a total of 5351 bicuspid aortic valve patients. During follow up, 184 bicuspid aortic valve patients presented infective endocarditis, with an incidence rate of 48.13 per 10,000 patients-year (95 %CI 22.24-74.02), and a 12-fold (RR: 12.03, 95 %CI 5.45-26.54) increased risk compared with general population, after adjusted estimates. Conclusions: This systematic review and meta-analysis suggests that bicuspid aortic valve patients have a significant high risk of native valve infective endocarditis. Large prospective high-quality studies are required to estimate more accurately the incidence of infective endocarditis, the relative risk and the potential benefit of antibiotic prophylaxis.

Direct oral anticoagulants vs vitamin K antagonist on dementia risk in atrial fibrillation: systematic review with meta-analysis.

Oral anticoagulation significantly reduces the incidence of dementia in atrial fibrillation patients. However, this protective effect has not been compared between Direct Oral Anticoagulants (DOAC) and Vitamin K antagonists' anticoagulants (VKA). We conducted an electronic search for potentially eligible studies through the bibliographic databases MEDLINE, CENTRAL, ClinicalTrials.gov, EMBASE and Web of Science. The outcome of interest was dementia. Random-effects meta-analysis was performed. Nine observational studies were included and 1,175,609 atrial fibrillation patients were enrolled. DOAC therapy was associated with a significant reduction when compared with patients under VKA therapy (hazard ratio 0.89; 95% confidence interval 0.80-0.99). The grade of confidence of our results was very low due to the risk of bias. DOAC therapy is associated with a significant decrease in the risk of dementia when compared with VKA therapy. However, the low certainty of the evidence along with the paucityof clinical trials dedicated to answering this important question underscores a need for global clinical research initiatives.

Shoulder Performance Activity Test (SPAT) for People With Shoulder Pain: Feasibility, Reliability, and Validity.

OBJECTIVE: The purpose of this study was to assess feasibility, reliability, and validity of a new performance-based test, the Shoulder Performance Activity Test (SPAT). METHODS: People with shoulder pain (n = 93) and without shoulder pain (n = 43) were included. The SPAT consists of overhead reach, hand behind head, and hand behind back tasks, each performed with 20 repetitions and rated by time, pain, and effort. The SPAT scores were summed for time, pain, and effort, and a total score across the 3 tasks. Feasibility was assessed by the percentage of SPAT task completion, test-retest reliability by intraclass correlation coefficient (ICC), standard error measurement, minimal detectable change, and known-groups construct validity by comparing between groups (shoulder pain and no pain) and between shoulders in those with pain. RESULTS: All participants performed the 3 SPAT tasks. The ICC was 0.74-0.91, and the minimal detectable change was 3.1-4.7 for task scores and 10.0 points for the total score. Individuals with pain presented higher tasks and total scores compared with those without pain. The moderate/severe pain group had higher scores than the low pain and no shoulder pain groups, and the low pain group had higher scores than the no pain group. Scores were higher in the involved shoulder compared with the uninvolved shoulder. CONCLUSION: The SPAT is a feasible and reliable performance-based test for use in patients with shoulder pain and can differentiate between individuals with and without pain, among different levels of pain, and between involved and uninvolved shoulders. IMPACT: The SPAT provides a standardized method for clinicians to assess shoulder functional performance tasks, which can enable a comprehensive assessment of shoulder disability and clinical decision making. The error metrics can be used to determine meaningful changes in performance.

Acute coronary syndrome and stress: Is there a relationship?

INTRODUCTION: Acute coronary syndrome (ACS) is the result of a complex pathophysiological process with various dynamic factors. The 10-item Perceived Stress Scale (PSS-10) is a validated instrument for estimating stress levels in clinical practice and may be useful in the assessment of ACS. METHODS: We carried out a single-center prospective study engaging patients hospitalized with ACS between March 20, 2019 and March 3, 2020. The PSS-10 was completed during the hospitalization period. The ACS group was compared to a control group (the general Portuguese population), and a subanalysis in the stress group were then performed. RESULTS: A total of 171 patients with ACS were included, of whom 36.5% presented ST-elevation myocardial infarction (STEMI), 38.1% were female and the mean PSS score was 19.5±7.1. Females in the control group scored 16.6±6.3 on the PSS-10 and control males scored 13.4±6.5. The female population with ACS scored 22.8±9.8 on the PSS-10 (p<0.001). Similarly, ACS males scored a mean of 17.4±6.4 (p<0.001). Pathological stress levels were not a predictor of major adverse cardiovascular events or severity at admission. CONCLUSIONS: ACS patients had higher perceived stress levels compared to the control group. Perceived stress level was not associated with worse prognosis in ACS patients.

Revascularization strategies in STEMI and multivessel disease.

INTRODUCTION: The main treatment for ST-elevation myocardial infarction (STEMI) is the re-establishment of the coronary flow of infarct-related arteries. However, 50% of cases present multivessel disease (MVD), negatively affecting mortality. Complete revascularization (CR) is currently advocated since it reduces major adverse cardiovascular events (MACE). OBJECTIVE: Evaluation of the adopted revascularization strategy and its prognostic value in a Portuguese cohort of STEMI patients with MVD. MATERIAL AND METHODS: Retrospective analysis of patients admitted with STEMI included in the Portuguese Registry of Acute Coronary Syndromes between 2010 and 2019. Patients were divided in two groups regarding revascularization strategy (complete versus incomplete) and compared. Independent predictors of a composite of all-cause mortality and rehospitalization for cardiovascular causes were assessed by multivariate logistic regression. RESULTS: A total of 3500 patients were included. A CR strategy was performed in 21.8% of patients, who were younger and healthier. They also presented more hemodynamically stable and had less kidney dysfunction and anaemia. Their coronary anatomy was less complex, with a higher prevalence of 2-vessel and a lower proportion of chronic occlusions. In-hospital and 1-year adverse events were less frequent between patients with CR. CONCLUSION: In hemodynamically stable STEMI patients, CR substantially reduced in-hospital and 1-year all-cause mortality and MACE.

Telerehabilitation-based trunk exercise training for motor symptoms of individuals with Parkinson's disease: A randomized controlled clinical trial.

BACKGROUND: Poor gait and static balance performance may be associated with trunk muscles in individuals with Parkinson's disease. AIM: The study aims at evaluating the effects of a home-based trunk exercise program on gait and balance performance in Parkinson's disease. METHODS: A randomized controlled trial was conducted with 28 individuals with Parkinson's disease with Hoehn & Yahr stage II-IV. The control group (n = 14) performed upper and lower limb exercises, while the experimental group (n = 14) engaged in a trunk exercise program. Both groups performed home-based exercises three times daily for 3 weeks. At the end of interventions (post-training) and 4 weeks after post-training (follow-up), static balance (force plate) and gait (motion capture system) were evaluated. Mixed analysis of variance compared time × group interaction (α = 5%). RESULTS: No time × group interaction was observed in the center of pressure displacement, center of pressure mean velocity, and anteroposterior and mediolateral center of pressure range during bipedal support with eyes opened and closed; and gait speed, hip, knee, and ankle range of motion during gait analysis. No intragroup differences were found. CONCLUSION: Trunk strengthening exercises did not improve gait and balance compared with upper and lower limb exercises. The non-adherence rate (33%) to the remote intervention may have also hindered our results.

High frequency of Depressive Disorders and Suicidal Phenomena in Late-Stage Parkinson´s Disease - A Cross-Sectional Study.

BACKGROUND: Depressive disorders (DD) are widely recognized as one of the most frequent neuropsychiatric disorders in Parkinson´s disease. Patients with late-stage Parkinson´s disease (LSPD) continue to be a neglected population, and little is known about DD frequency in LSPD. OBJECTIVES: To determine the frequency of DD in LSPD patients through a clinical diagnostic interview (CDI) and according to diagnostic DSM- 5 criteria. Secondary objectives were to determine the predictive ability of depressive scales to detect DD, to identify potential predictors of DD in LSPD and, to evaluate suicidal phenomena in LSPD. METHODS: A cross-sectional study including LSPD patients (≥7 years from symptom onset and Hoehn and Yahr scale score >3 or a Schwab and England scale score <50% in the ON condition) was conducted. Patients were subjected to psychiatric, neurological, and neuropsychological evaluations. Six depression scales were applied. RESULTS: 92 LSPD patients were included. 59.78% of LSPD patients had a current diagnosis of DD according to CDI, 38.04% patients had a diagnosis of major depressive disorder, and 21.72% non-major depressive disorder. Suicidal ideation was present in 36.96% of patients. All applied scales were able to detect depressive disorders. CONCLUSIONS: More than half of LSPD patients met DD diagnostic criteria and over one-third were diagnosed with major depressive disorder. Overall, the LSPD population seem to have a unique clinical phenotype regarding the frequency and features of DD, whose early identification and treatment could improve the quality of life of patients and caregivers.

Relationships Between Active Myofascial Trigger Points and Depressive Symptoms and Physical and Clinical Characteristics of Individuals With Shoulder Pain: A Cross-sectional Study.

Objective: The purpose of this study was to evaluate relationships between the presence and number of active myofascial trigger points (MTPs) in shoulder muscles and physical and demographic characteristics, depressive symptoms, pain and function, range of motion (ROM), and strength in individuals with shoulder pain. Methods: Fifty-eight individuals were assessed for physical and demographic characteristics, depressive symptoms, shoulder pain and function, MTPs (upper and lower trapezius, infraspinatus, and supraspinatus), shoulder ROM and strength test, and pain during ROM and strength test. Relationships were verified using point-biserial (rpb), Spearman correlation test, and multiple linear regression analysis. Results: We found weak to moderate (P < .05) correlations between presence and number of MTPs and depressive symptoms (rpb, 0.28-0.32), pain during ROM (rpb, 0.36-0.40), pain during strength test (rpb, 0.29-0.38), and shoulder function (rpb, -0.29 to 0.33) and strength (rpb, 0.26-0.34). MTPs in the infraspinatus contributed 10% (R² = 0.10; P < .05) to depressive symptoms; in the upper and lower trapezius contributed 27% (R² = 0.27; P < .05) to pain during internal rotation ROM; in the upper trapezius contributed 15% (R² = 0.15; P < .01) to pain during internal rotation strength test and 14% to pain during internal rotation ROM (R² = 0.14; P < .01); and in the supraspinatus contributed 17% (R² = 0.17; P < .01) to pain during external rotation ROM. Conclusion: This study found that MTPs in individuals with shoulder pain contributed to depressive symptoms and pain during internal and external rotation ROM and internal rotation strength test.

Characteristics of Oral Corticosteroid Users Among Persons with Asthma on GINA Step 3 Therapy and Above: A Cross-Sectional Study in Portuguese Community Pharmacies.

Purpose: Oral corticosteroids (OCS) are frequently used in asthma management but have an important risk-profile. The aim of the study is to characterize and compare the sociodemographic and clinical characteristics, treatment regimen and asthma control between OCS users and non-users among the population of asthma patients (≥18 years) at GINA step 3 and above treated with a fixed combination of an inhaled corticosteroid and a long-acting beta-agonist (ICS/LABA). Methods: Cross-sectional study in Portuguese community pharmacies. Data was collected via paper-based interview delivered at the pharmacy (sociodemographic characteristics and asthma treatment regimen, namely ICS/LABA and OCS utilization), followed by a telephonic interview collecting smoking history, comorbidities, body mass index (BMI), history of exacerbations and asthma-related healthcare resource utilization (HCRU) in the previous 12 months, as well as asthma control using the Control of Allergic Rhinitis and Asthma Test (CARAT®). Results: A total of 347 patients recruited in 98 pharmacies were included in the analysis. Of those, 328 had completed both questionnaires. A quarter of the individuals reported OCS use in the previous 12 months (OCS users), either as add-on therapy (6%) or exacerbation treatment (19%). Patients were mostly females (72%), with an average age of 59.5 years (SD=15.4). OCS users were significantly older and reported more frequently having conjunctivitis (25.9% vs 15.0%), osteoporosis (25.9% vs 13.4%), arthritis (14.6% vs 6.9%), and gastrointestinal disease (16.1% vs 8.1%). OCS users also reported greater urgent HCRU: unscheduled consultations (33.3% vs 9.3%) and emergency department (ED) visits (32.1% vs 12.1%). Both groups presented poor disease control (85.2% of OCS users vs 72.9% of non-OCS users). Conclusion: These results highlight the burden of OCS therapy to asthma patients and the need to improve asthma management, by adopting OCS sparing strategies in this subgroup of patients.

Prognostic value of brain natriuretic peptide in ST-elevation myocardial infarction patients: A Portuguese registry.

INTRODUCTION: Brain natriuretic peptide (BNP) is a highly sensitive and specific biomarker for the extent of myocardial infarction that is strongly related to short- and long-term prognosis in patients with acute coronary syndromes. OBJECTIVE: To assess the prognostic value of BNP levels in a Portuguese cohort of ST-elevation myocardial infarction (STEMI) patients. METHODS: We performed a retrospective analysis of patients admitted with STEMI included in the Portuguese Registry of Acute Coronary Syndromes (ProACS) between 2010 and 2019. Patients were divided into three groups according to BNP level (<100 pg/ml, 100-399 pg/ml and ≥400 pg/ml) and compared. Independent predictors of a composite of all-cause mortality and rehospitalization for cardiovascular causes were assessed by multivariate logistic regression. For sample homogenization, propensity score matching and pairwise matching with a tolerance level of 0.005 were performed. RESULTS: A total of 1650 patients were included, of whom 21.5% presented high BNP levels (≥400 pg/ml). These were older and had more comorbidities, lower admission systolic blood pressure and hemoglobin, higher heart rate, Killip class and creatinine, worse left ventricular systolic function and severe coronary anatomy. Higher BNP was associated with more in-hospital complications, in-hospital mortality and adverse outcomes at one year. CONCLUSION: BNP levels during the index hospitalization were a powerful prognostic biomarker for all-cause mortality and major adverse cardiac events in patients admitted with STEMI to Portuguese hospitals.
