Effectiveness of balneotherapy in reducing pain, disability, and depression in patients with Fibromyalgia syndrome: a systematic review with meta-analysis.

Balneotherapy, using heated natural mineral waters at 36-38 °C, presents a comprehensive treatment approach for Fibromyalgia Syndrome (FMS). This study aims to assess the effect of balneotherapy in reducing pain intensity, disability, and depression in patients with FMS. We want to assess this effect at just four time-points: immediately at the end of the therapy, and at 1, 3, and 6 months of follow-up. Following PRISMA guidelines, we conducted an aggregate data meta-analysis, registered in PROSPERO CRD42023478206, searching PubMed Medline, Science Direct, CINAHL Complete, Scopus, and Web of Science until August 2023 for relevant randomized controlled trials (RCTs) that assess the effect of balneotherapy on pain intensity, disability, and depression in FMS patients. Methodological quality was assessed using the Cochrane methodology, and the pooled effect was calculated using Cohen's standardized mean difference (SMD) and its 95% confidence interval (95% CI) in a random-effects model. Sixteen RCTs were included in the meta-analysis. Balneotherapy is effective in reducing pain intensity (SMD - 1.67; 95% CI -2.18 to -1.16), disability (SMD - 1.1; 95% CI -1.46 to -0.7), and depression (SMD - 0.51; 95% CI -0.93 to -0.9) at the end of the intervention. This effect was maintained at 1, 3, and 6 months for pain intensity and disability. Balneotherapy improves both pain intensity and disability in patients with FMS, providing evidence that its positive effects are sustained for up to 6 months of follow-up. Nevertheless, it is important to note that the improvement in depression varies across different temporal phases.

Domestic Dog Infection with Trypanosoma cruzi from Northern and Southern Regions of Mexico.

Background: Chagas disease or American trypanosomiasis, caused by Trypanosoma cruzi and vectored by triatomines, affects millions of people worldwide. In endemic countries including Mexico, infections in domestic animals, such as dogs, may affect the risk of human disease when they serve as a source of infection to vectors that subsequently infect humans. Materials and Methods: We conducted a cross-sectional study of 296 dogs from two cities near the northern and southern borders of Mexico: Reynosa, Tamaulipas, and Tuxtla Gutierrez, Chiapas. Infection was measured based on testing of blood using T. cruzi quantitative PCR (qPCR) and up to three antibody detection assays. The StatPak immunochromatographic assay was used to screen samples and the indirect fluorescent antibody (IFA) and multiplex microsphere immunoassay (MIA) tests were used as secondary tests on all samples that screened positive and a subset of negatives. Serologic positivity was defined based on reactivity on at least two independent tests. Results: Of the 280 samples tested for parasite DNA, two (0.7%) were positive, one of which (0.4%) was confirmed as T. cruzi discrete typing unit TcIV. Overall, 72 (24.3%) samples were reactive for T. cruzi antibodies via StatPak of which 8 were also positive using MIA and 2 were also positive using IFA (including one of the PCR-positive dogs). Overall, nine dogs (3.4%) met study criteria of positivity based on either/both serology or PCR tests. Positive dogs were found in both regions of Mexico; five (2.7%) from Reynosa and four (3.6%) from Tuxtla Gutierrez. We found no association between infection status and state of origin, sex, age group, breed group, neighborhood, and whether other pets lived in the home. Conclusion: Our results re-emphasize dogs' utility as sentinels for T. cruzi in Mexico and underscore the need for improved veterinary diagnostic tests and parasite surveillance at the household level in endemic countries.

Virtual reality-based therapy for chronic low back and neck pain: a systematic review with meta-analysis.

Purpose: To compile all the scientific evidence available to date to evaluate the effect of virtual reality based therapy (VRBT) on reducing pain intensity, kinesiophobia, and associated disability, and on increasing the hr-QoL in patients with chronic neck pain (CNP) or chronic low back pain (CLBP). Methods: Studies published in PubMed Medline, SCOPUS, Web of Science, CINAHL Complete, and Physiotherapy Evidence Database (PEDro) up to June 2023 were searched. All searches followed the PICOS Framework. Two authors independently screened the studies found in the searches. Any differences of opinion regarding the selection of studies were settled by a third author. Results: Twenty-five RCTs, published between 2013 and 2022, providing data from 1261 patients (20 RCTs) with CLBP and 261 patients (five RCTs) with CNP, were included. In reducing pain intensity for patients with CLBP, meta-analyses showed that VRBT is effective in reducing pain just to the end of the intervention, and this effect could be maintained 1 and 6 months after the therapy. Conclusion: VRBT was found to be better than therapeutic exercise (TE), sham, and no intervention (NI), showing a major effect when VRBT was used as a complementary therapy to conventional physiotherapy (CPT). Further, VRBT showed an immediate effect and immersive VRBT was the most adequate VRBT modality in reducing pain in CNP patients. No differences were found between non-immersive VRBT and immersive VRBT in reducing pain, kinesiophobia, disability, and hr-QoL in patients with CLBP.

Vitamin D3 (Calcitriol) Monotherapy Decreases Tumor Growth, Increases Survival, and Correlates with Low Neutrophil-to-Lymphocyte Ratio in a Murine HPV-16-Related Cancer Model.

Vitamin D3 or calcitriol (VitD3) has been shown to have anticancer and anti-inflammatory activity in in vitro models and clinical studies. However, its effect on HPV-16-related cancer has been sparsely explored. In this study, we aimed to determine whether monotherapy or combination therapy with cisplatin (CP) reduces tumor growth and affects survival and systemic inflammation. Treatments were administered to C57BL/6 mice with HPV-16-related tumors (TC-1 cells) as follows: (1) placebo (100 µL vehicle, olive oil, orally administered daily); (2) VitD3 (3.75 µg/kg calcitriol orally administered daily); (3) CP (5 mg/kg intraperitoneally, every 7 days); and (4) VitD3+CP. Tumor growth was monitored for 25 days, survival for 60 days, and the neutrophil-to-lymphocyte ratio (NLR) was evaluated on days 1 (baseline), 7, and 14. VitD3+CP showed greater success in reducing tumor volume compared to CP monotherapy (p = 0.041), while no differences were observed between CP and VitD3 monotherapy (p = 0.671). Furthermore, VitD3+CP prolonged survival compared to CP (p = 0.036) and VitD3 (p = 0.007). Additionally, at day 14 the VitD3 and VitD3+CP groups showed significantly lower NLR values than the CP group (p < 0.05, for both comparisons). Vitamin D3 could be a promising adjuvant in the treatment of cervical cancer or solid tumors and deserves further investigation.

Disseminated peritoneal leiomyomatosis mimicking carcinomatosis: A case report.

INTRODUCTION AND IMPORTANCE: Disseminated Peritoneal Leiomyomatosis (DPL) is a rare benign proliferation of solid peritoneal lesions along the abdominopelvic cavity comprised of smooth muscle and connective tissue. Though hormonal and iatrogenic causes have been theorized, the exact etiology remains unknown. Most patients with DPL are frequently premenopausal with a history of myomectomy or prior hysterectomy. These patients can present asymptomatically or with abnormal uterine bleeding and abdominal discomfort. DPL is a rare entity with less than 150 cases reported in the literature, showcasing the need of awareness of this poorly understood neoplasm. Imaging, if performed, is helpful as positron emission tomography (PET) can differentiate DPL from malignant peritoneal disease. Treatment involves medical and surgical options based on patient's clinical presentation, with medical treatment with gonadotropin-releasing hormone agonist being first line. CASE PRESENTATION: We report a case of a previously healthy female presenting for desired laparoscopic tubal ligation with incidental countless peritoneal nodules suspicious for carcinomatosis found during the operative event but proven leiomyomas after histologic examination. CLINICAL DISCUSSION: Differentiating DPL from mimickers such as leiomyosarcoma, endometriosis, and carcinomatosis remains a challenge as macroscopic appearances are similar ultimately requiring histology evaluation. CONCLUSION: Awareness of the entity is crucial to avoid misdiagnosis and unnecessary anxiety associated with a presumptive diagnosis of malignancy for a largely benign entity.

Effects of monopolar pulsed-capacitive dielectric radiofrequency diathermy in patients with chronic low back pain: a randomised clinical trial.

Monopolar capacitive diathermy is a physiotherapy technique that uses high-frequency currents to generate heat in deep tissues. This heat can have several therapeutic effects, especially in the treatment of chronic low back pain (CLBP), however, until now there is little evidence of this type of diathermy. The purpose was to evaluate the efficacy of a pulsed monopolar dielectric radiofrequency diathermy (PRF)-capacitive type versus simulated treatment on symptomatology of patients with CLBP. A single-blind randomised controlled trial was conducted. Sixty patients with CLBP were randomly assigned to a PRF-capacitive or a simulated treatment group. All participants received 3 sessions per week for 3 weeks. Disability, pain intensity, movement phobia, lumbar anteflexion, quality of life, and sleep quality were assessed at baseline, after treatment, and at two months. The application of 9 sessions of PRF-capacitive showed significant improvements compared to simulated therapy during the entire follow-up for disability (F = 26.99, p < 0.001), pain intensity (F = 0.550, p < 0.001), the quality of life components of physical function (F = 0.780, p < 0.001), social function (F = 0.780, p < 0.001) and mental health (F = 0.858, p = 0.003) and for sleep duration (F = 0.863, p = 0.004).

Time­dependent ROC curve analysis to determine the predictive capacity of seven clinical scales for mortality in patients with COVID­19: Study of a hospital cohort with very high mortality.

Clinical data from hospital admissions are typically utilized to determine the prognostic capacity of Coronavirus disease 2019 (COVID-19) indices. However, as disease status and severity markers evolve over time, time-dependent receiver operating characteristic (ROC) curve analysis becomes more appropriate. The present analysis assessed predictive power for death at various time points throughout patient hospitalization. In a cohort study involving 515 hospitalized patients (General Hospital Number 1 of Mexican Social Security Institute, Colima, Mexico from February 2021 to December 2022) with COVID-19, seven severity indices [Pneumonia Severity Index (PSI) PaO2/FiO2 arterial oxygen pressure/fraction of inspired oxygen (Kirby index), the Critical Illness Risk Score (COVID-GRAM), the National Early Warning Score 2 (NEWS-2), the quick Sequential Organ Failure Assessment score (qSOFA), the Fibrosis-4 index (FIB-4) and the Viral Pneumonia Mortality Score (MuLBSTA were evaluated using time-dependent ROC curves. Clinical data were collected at admission and at 2, 4, 6 and 8 days into hospitalization. The study calculated the area under the curve (AUC), sensitivity, specificity, and predictive values for each index at these time points. Mortality was 43.9%. Throughout all time points, NEWS-2 demonstrated the highest predictive power for mortality, as indicated by its AUC values. PSI and COVID-GRAM followed, with predictive power increasing as hospitalization duration progressed. Additionally, NEWS-2 exhibited the highest sensitivity (>96% in all periods) but showed low specificity, which increased from 22.9% at admission to 58.1% by day 8. PSI displayed good predictive capacity from admission to day 6 and excellent predictive power at day 8 and its sensitivity remained >80% throughout all periods, with moderate specificity (70.6-77.3%). COVID-GRAM demonstrated good predictive capacity across all periods, with high sensitivity (84.2-87.3%) but low-to-moderate specificity (61.5-67.6%). The qSOFA index initially had poor predictive power upon admission but improved after 4 days. FIB-4 had a statistically significant predictive capacity in all periods (P=0.001), but with limited clinical value (AUC, 0.639-0.698), and with low sensitivity and specificity. MuLBSTA and IKIRBY exhibited low predictive power at admission and no power after 6 days. In conclusion, in COVID-19 patients with high mortality rates, NEWS-2 and PSI consistently exhibited predictive power for death during hospital stay, with PSI demonstrating the best balance between sensitivity and specificity.

Glycemic Index, Glycemic Load and Dyslipidemia in Adolescents from Chiapas, Mexico.

Cardiovascular disease risk throughout the life course is increased by abnormal blood lipid levels in youth. The dietary glycemic index (GI) and glycemic load (GL) during adolescence might be related to abnormal blood lipids. This study aimed to analyze the association between dietary GI, GL and dyslipidemia in adolescents from two marginalized regions of Chiapas, Mexico. A cross-sectional study was conducted with 213 adolescents. Food intake was assessed using 24 h recalls. The association between dyslipidemia and dietary GI or GL was tested by using logistic regression models. Low HDL-c was the most prevalent risk factor (47.4%), followed by hypertriglyceridemia (25.4%). In this population, overall dietary GI was not associated with dyslipidemia. A high dietary GL was associated with 2.39 higher odds of low HDL-c (95% CI: 1.21-4.74) when compared to low GL. Female adolescents with high dietary GL had 3.20 higher odds of hypertriglyceridemia (95% CI: 1.03-9.88), whereas no association was found for males. No associations were observed between overall dietary GL and total cholesterol or LDL-c. In adolescents from urban and rural communities in Chiapas, a high dietary GL was associated with a detrimental effect on HDL-c. In female adolescents, high GL was associated with hypertriglyceridemia.

Effectiveness of transcutaneous electrical nerve stimulation improves pain intensity, disability and quality of life in patients with fibromyalgia syndrome: a systematic review with meta-analysis.

PURPOSE: The transcutaneous electrical nerve stimulation (TENS) is one of the most frequently electrophysical agents employed in reducing the impact of FMS. This meta-analysis intended to determine the effectiveness of TENS on pain, disability, and quality of life (QoL) in patients with FMS. METHODS: According to PRISMA, we performed a meta-analysis (CRD42023456439), searching in PubMed Medline, PEDro, CINAHL Complete, Web of Science, and Scopus, since inception up to October 2023. This review focused on controlled clinical trials evaluating the effect of TENS on pain, disability, and QoL in patients with FMS. The pooled effect was estimated using Cohen's standardized mean difference (SMD) and its 95% confidence interval (95%CI). RESULTS: Twelve studies, providing data from 944 patients, were included (PEDro score of 5.6 points). Meta-analyses showed that TENS interventions are effective in improving pain (SMD = -0.61; 95%CI -1 to -0.16); disability (SMD = -0.27; 95%CI -0.41 to -0.12); and physical dimension of QoL (SMD = 0.26; 95%CI 0.08 to 0.44). Additionally, when TENS is used as a unique therapy, it represents the best therapeutic option for improving pain, disability, and QoL. CONCLUSIONS: This meta-analysis, including the largest number of studies, showed that TENS intervention is an effective therapy to reduce pain and disability and increase QoL in FMS patients.

Transcutaneous Electrical Nerve Stimulation (TENS) intervention is effective in reducing pain and disability; and increasing physical quality of life (QoL) in patients with Fibromyalgia Syndrome (FMS).Compared to sham or no intervention, TENS is more effectiveness for improving pain, disability and QoL is major when it is applied as isolated therapy in patients with FMS.In comparison to therapeutic exercise, TENS did not show to be better in reducing pain and disability in patients with FMS, suggesting the importance of considering combined or alternative treatments.

DTUs were determined using conventional and nested PCR. RESULTS: The infection rate was 43.6%. All insects were infected with TcI while one specimen showed mixed infection with TcII. CONCLUSIONS: This is the first report of T. cruzi mixed infection in Triatoma phyllosoma, its main vector in the study region.

Immersive virtual reality and augmented reality in anatomy education: A systematic review and meta-analysis.

The purpose of this review was to (1) analyze the effectiveness of immersive virtual reality (iVR) and augmented reality (AR) as teaching/learning resources (collectively called XR-technologies) for gaining anatomy knowledge compared to traditional approaches and (2) gauge students' perceptions of the usefulness of these technologies as learning tools. This meta-analysis, previously registered in PROSPERO (CRD42023423017), followed PRISMA guidelines. A systematic bibliographical search, without time parameters, was conducted through four databases until June 2023. A meta-analytic approach investigated knowledge gains and XR's usefulness for learning. Pooled effect sizes were estimated using Cohen's standardized mean difference (SMD) and 95% confidence intervals (95% CI). A single-group proportional meta-analysis was conducted to quantify the percentage of students who considered XR devices useful for their learning. Twenty-seven experimental studies, reporting data from 2199 health sciences students, were included for analysis. XR-technologies yielded higher knowledge gains than traditional approaches (SMD = 0.40; 95% CI = 0.22 to 0.60), especially when used as supplemental/complementary learning resources (SMD = 0.52; 95% CI = 0.40 to 0.63). Specifically, knowledge performance using XR devices outperformed textbooks and atlases (SMD = 0.32; 95% CI = 0.10 to 0.54) and didactic lectures (SMD = 1.00; 95% CI = 0.57 to 1.42), especially among undergraduate students (SMD = 0.41; 95% CI = 0.20 to 0.62). XR devices were perceived to be more useful for learning than traditional approaches (SMD = 0.54; 95% CI = 0.04 to 1), and 80% of all students who used XR devices reported these devices as useful for learning anatomy. Learners using XR technologies demonstrated increased anatomy knowledge gains and considered these technologies useful for learning anatomy.

Effectiveness of virtual reality-based therapy in pulmonary rehabilitation of chronic obstructive pulmonary disease. A systematic review with meta-analysis.

BACKGROUND: In addition to conventional pulmonary rehabilitation (PR) programs for the treatment of chronic obstructive pulmonary disease (COPD), the use of virtual reality-based therapy (VRBT) has been proposed as an effective complementary tool to be included in PR programs for COPD. OBJECTIVES: To analyze the effectiveness of VRBT on functional capacity, pulmonary function, and functional mobility in patients with COPD. METHODS: A meta-analysis was carried out through a bibliographic search in PubMed (Medline), WOS, PEDro, CINAHL, CENTRAL, and Scopus since inception up to June 2023. The risk of bias was assessed using the PEDro scale, and the effect was determined using the standardized mean difference (SMD) and its 95 % confidence interval (95 % CI) in a random effects model. RESULTS: Five RCTs, providing data from 344 participants with a mean age 65.7 ± 5.3 years old, were included. The mean methodological quality of the studies included was good (6.8 ± 1.6 points). The meta-analysis showed that VRBT was effective in increasing functional capacity, assessed with the 6 Min Walking Test, (SMD=0.4, 95 % CI 0.07 to 0.71, p = 0.017); pulmonary function, assessed with FEV1 (SMD=0.33, 95 %CI 0.01 to 0.65, p = 0.048); and functional mobility, assessed with the Get Up and Go Test (SMD=0.77, 95 % CI 0.5 to 1.1, p<0.001) in patients with COPD. CONCLUSION: VRBT is suggested to be effective in increasing functional capacity, pulmonary function, and functional mobility in patients with COPD. Non-immersive VRBT is the most used modality of VRBT in PR.

Non-Immersive Virtual Reality-Based Therapy Applied in Cardiac Rehabilitation: A Systematic Review with Meta-Analysis.

BACKGROUND: The aim of this systematic review with meta-analysis was to assess the effectiveness of non-immersive virtual reality (niVR) active videogames in patients who underwent cardiac rehabilitation (CR). METHODS: A systematic review with meta-analysis, according to the PRISMA guidelines and previously registered in PROSPERO (CRD42023485240), was performed through a literature search in PubMed (Medline), SCOPUS, WOS, and PEDro since inception to 21 November 2023. We included randomized controlled trials (RCTs) that assessed the effectiveness of an niVR intervention, in comparison with conventional CR and usual care, on aerobic capacity and cardiovascular endurance (physical function), anxiety, depression, and quality of life (QoL). The risk of bias in individual studies was assessed using the Cochrane risk of bias tool. Effect size was estimated using Cohen's standardized mean difference (SMD) and its 95% confidence interval (95% CI) in a random-effects model. RESULTS: Nine RCT that met the inclusion criteria were included in the meta-analysis. The meta-analysis showed a moderate-to-large effect favoring niVR active videogames included in CR in increasing aerobic capacity and cardiovascular endurance (SMD = 0.74; 95% CI 0.11 to 1.37; p = 0.021) and reducing anxiety (SMD = -0.66; 95% CI -1.13 to -0.2; p = 0.006). Only 4.8% of patients reported adverse events while performing niVR active videogames. CONCLUSIONS: Inclusion of niVR active videogames in CR programs is more effective than conventional CR in improving aerobic capacity and cardiovascular endurance and in reducing anxiety.

Electrical dry needling versus a non-invasive multicomponent intervention in the treatment of myofascial trigger points in patients with chronic low back pain: A randomised clinical trial.

OBJECTIVE: To compare the effects of electrical dry needling with a non-invasive multi-component intervention in patients with chronic low back pain. DESIGN: A randomised single-blind clinical trial. SETTING: Outpatient Physiotherapy Clinic; home. PARTICIPANTS: Sixty-four patients with chronic low back pain aged 30-65 years. INTERVENTIONS: Six-week electrical dry needling on myofascial trigger points, and a non-invasive multicomponent intervention (home exercise programme, stretching and ischemic compression). MAIN MEASURES: Pain (Visual Analogue Scale), disability (Roland-Morris Disability Questionnaire and Oswestry Disability Index), kinesiophobia (Tampa Scale of Kinesiophobia), quality of life and sleep (Short Form 36-item Health Survey and Pittsburgh Sleep Quality Index), isometric endurance of trunk flexor muscles (McQuade test), lumbar mobility in flexion (finger-to-floor distance), and pressure pain threshold (algometer) were assessed at baseline, after 6 weeks, and after 2 months. RESULTS: ANOVA showed statistically significant differences in group-by-time interaction for most pain pressure thresholds of myofascial trigger points (P < 0.05), for disability (Roland-Morris Disability Questionnaire: F = 6.14, P = 0.016; and Oswestry Disability Index: F = 7.36, P = 0.009), for trunk anteflexion (F = 10.03, P = 0.002) and for habitual sleep efficacy (F = 6.65, P = 0.012), use of hypnotics (F = 4.77, P = 0.033) and total score of quality of sleep (F = 8.23, P = 0.006). CONCLUSIONS: In comparison to a non-invasive multicomponent intervention, electrical dry needling has more positive effects on disability, pain intensity, kinesiophobia, and reducing patients' sensitivity to myofascial trigger points pressure, at post-treatment and at 2 months. CLINICAL TRIAL REGISTRATION NUMBER: NCT04804228. Registered on May 28th, 2021. Available at https://clinicaltrials.gov/ct2/show/NCT04804228.

Sociodemographic inequalities in cardiovascular risk factors among adolescents from indigenous areas in Chiapas, Mexico.

This study was aimed to determine the prevalence of cardiovascular risk factors among different sociodemographic groups of adolescents from indigenous communities in Chiapas, Mexico. A cross-sectional prevalence study was performed in urban and rural communities in the Tzotzil-Tzeltal and Selva regions of Chiapas. A sample of 253 adolescents was studied, of whom 48% were girls and 52% were boys. A descriptive analysis of quantitative variables was performed using measures of central tendency and dispersion. The prevalence of cardiovascular risk factors stratified by sex, geographical area, years of schooling, and ethnicity of the mothers was estimated. The prevalence of cardiovascular risk factors was analyzed in relation to the sociodemographic characteristics of the study population. Low HDL-c (51%) was the predominant cardiovascular risk factor. Girls had a higher prevalence of abdominal obesity, hypertriglyceridemia, and borderline total cholesterol than boys. High diastolic blood pressure was more prevalent in boys. Adolescents from urban areas had a higher prevalence of overweight/obesity and insulin resistance than adolescents from rural areas. The prevalence of overweight/obesity and abdominal obesity was higher in adolescents whose mothers had ≥ 7 years of schooling compared with adolescents with less educated mothers. Differences by maternal ethnicity also influenced the prevalence of insulin resistance. Among the main findings, this study associated sociodemographic and geographical inequalities with cardiovascular risk factors. Promoting a healthy lifestyle for this young population is absolutely necessary to prevent cardiovascular diseases in adulthood.

TMEM127 suppresses tumor development by promoting RET ubiquitination, positioning, and degradation.

The TMEM127 gene encodes a transmembrane protein of poorly known function that is mutated in pheochromocytomas, neural crest-derived tumors of adrenomedullary cells. Here, we report that, at single-nucleus resolution, TMEM127-mutant tumors share precursor cells and transcription regulatory elements with pheochromocytomas carrying mutations of the tyrosine kinase receptor RET. Additionally, TMEM127-mutant pheochromocytomas, human cells, and mouse knockout models of TMEM127 accumulate RET and increase its signaling. TMEM127 contributes to RET cellular positioning, trafficking, and lysosome-mediated degradation. Mechanistically, TMEM127 binds to RET and recruits the NEDD4 E3 ubiquitin ligase for RET ubiquitination and degradation via TMEM127 C-terminal PxxY motifs. Lastly, increased cell proliferation and tumor burden after TMEM127 loss can be reversed by selective RET inhibitors in vitro and in vivo. Our results define TMEM127 as a component of the ubiquitin system and identify aberrant RET stabilization as a likely mechanism through which TMEM127 loss-of-function mutations cause pheochromocytoma.

First Report of Eratyrus cuspidatus (Hemiptera: Reduviidae) Infected with Trypanosoma cruzi in Peridomestic Environment in Chiapas, Mexico.

Background: Triatomine bugs are natural vectors of Trypanosoma cruzi, which causes Chagas disease or American trypanosomiasis. The role of sylvatic triatomine species as vectors of T. cruzi in Mexico remains to be fully understood. Our research on the epidemiology of Chagas disease in Southeastern Mexico involved sampling triatomines in rural settings. Materials and Methods: A triatomine was collected in a peridomestic environment of a rural dwelling in the state of Chiapas. The triatomine was identified morphologically as an adult female Eratyrus cuspidatus Stal. Results: Microscopic analysis revealed flagellate forms of T. cruzi in the feces of the E. cuspidatus collected. This was confirmed by quantitative polymerase chain reaction. Amplification of the mini-exon gene showed that the T. cruzi infecting E. cuspidatus corresponded to lineage I. Conclusions: This is the first report from Mexico of E. cuspidatus found infected in a human dwelling, which represents an important adaptation process to inhabit human environments.

Efficacy of Dual-Task Training in Patients with Parkinson's Disease: A Systematic Review with Meta-Analysis.

Background: Dual-task training (DTT) involves simultaneously motor and cognitive exercises. Objectives: To determine the effectiveness of DTT, in comparison to other interventions [single-task training (STT) and usual care (UC)], on gait and balance parameters, motor impairments, activities of daily living (ADLs) and quality of life (QoL) in patients with Parkinson's disease (PD) immediately post-intervention and at 3, 6, and 12 months after therapy. Methods: A meta-analysis was performed following PRISMA Guidelines through searching in PubMed, SCOPUS, WOS, CINAHL, SciELO and PEDro up to September 2022. We included randomized controlled trials (RCTs) that compare the effect of DTT versus STT and UC on gait (speed, step and stride length, cadence and steps per day), balance (functional and dynamic balance), motor impairments, ADLs and QoL. Methodological quality was assessed using the PEDro scale. The pooled effect was calculated through Cohen's Standardized Mean Difference (SMD) and its 95% confidence interval (95%CI). Results: Seventeen RCTs with 826 participants and a mean PEDro score of 6.59 ± 1 points were included. In comparison to STT and UC, DTT is effective in improving walking speed (SMD 0.42, 95%CI 0.23-0.6), stride length (SMD 0.69, 95%CI 0.23-1.15), cadence (SMD 0.41, 95%CI 0.19-0.63), functional balance (SMD 1.15, 95%CI 0.92-1.4), dynamic balance (SMD -0.5, 95%CI -0.81 to -0.18) and motor impairments (SMD -0.86, 95%CI -1.25 to -0.47). No adverse effects related to DTT were reported. Conclusions: DTT is an effective and safe therapy for improving gait, balance and motor impairments in patients with PD.
