RESUMO
Aims: Investigate whether a Home-based Exercise Therapy (HBET) program for patients with Peripheral Arterial Disease (PAD) and Intermittent Claudication (IC) with a behavior change intervention, supported by a smartphone application, is effective in improving walking distances and performance, and quality of life (QoL) over 6 months. Methods and results: This was a single-center, prospective, two-arm, single-blinded randomized controlled trial including 73 patients with PAD and IC, and three assessment moments: baseline, 3, and 6 months. Participants were randomized to receive a walking exercise prescription, with the support (n = 38) or without the support (n = 35) of the WalkingPad app, between January 2021 and July 2022. Both groups received two face-to-face behavior change sessions and 12 structured and targeted reinforcement phone calls over 6 months. Primary outcomes were between-group differences in pain-free walking distance (PFWD), functional walking distance (FWD), maximal walking distance (MWD), and 6-min walk distance (6â MWD) at 3 and 6 months. Secondary outcomes were QoL and walking impairment. Seventy-three patients (mean age 64 ± 7.2 years, 88% men) participated in this study, 60 of whom completed the three assessment moments. The whole sample significantly improved all primary outcomes in the first 3 months; that is, the average PFWD (151.1â m), FWD (175.2â m), MWD (171.1â m), and 6â MWD (30.8â m) increased from T1 to T2. Only MWD exhibited a significant average increase (35.0â m). Secondary outcomes also increased from baseline to 3 and 6 months. There were no between-group differences, except for MWD, which showed a greater increase at 6 months in the group that used the app, excluding patients with weak walking ability and extreme anxiety symptoms at baseline. Conclusion: The intervention improved distances and walking skills as well as the physical, mental, and disease-related quality of life among adults with PAD and IC. The group that used the WalkingPad app improved their MWD in 6 months compared to the control group, except for patients with poor walking ability and extreme anxiety symptoms, which suggests the effectiveness of the WalkingPad app for patients with high walking ability and no severe anxiety symptoms. More research is needed to determine the durability of these findings and to explore what app functionality might promote the other outcomes.

RESUMO
INTRODUCTION: Exercise-induced microRNA (miRNA) expression has been implicated in the regulation of skeletal muscle plasticity. However, the specificity and acute time course in miRNA expression after divergent exercise modes are unknown. In a randomized crossover design, we compared the acute expression profile of eight skeletal muscle miRNAs previously reported to be involved in skeletal muscle development, growth, and maintenance after a bout of either resistance exercise (RE), high-intensity interval exercise (HIIE), and concurrent resistance and high-intensity interval exercises (CE). METHODS: Nine untrained young men (23.9 ± 2.8 yr, 70.1 ± 14.9 kg, 177.2 ± 3.0 cm, 41.4 ± 5.2 mL·kg-1·min-1) underwent a counterbalanced crossover design in which they performed bouts of RE (2 × 10 repetitions maximum 45° leg press and leg extension exercises), HIEE (12 × 1-min sprints at VËO2peak with 1-min rest intervals between sprints), and CE (RE followed by HIIE), separated by 1 wk. Vastus lateralis biopsies were harvested immediately before (Pre) and immediately (0 h), 4 h, and 8 h after each exercise bout. RESULTS: There were similar increases (main effect of time; P < 0.05) in miR-1-3p, miR-133a-3p, miR-133b, miR-181a-3p, and miR-486 expression at 8 h from Pre with all exercise modes. Besides a main effect of time, miR-23a-3p and miR-206 presented a main effect of condition with lower expression after HIIE compared with RE and CE. CONCLUSIONS: Select miRNAs (miR-1-3p, miR-133a-3p, miR-133b, miR-23a-3p, miR-181a-3p, miR-206, miR-486) do not exhibit an expression specificity in the acute recovery period after a single bout of RE, HIIE, or CE in skeletal muscle. Our data also indicate that RE has a higher effect on the expression of miR-23a-3p and miR-206 than HIIE. As upregulation of these miRNAs seems to be confined to the 8-h period after exercise, this may subsequently affect the expression patterns of target mRNAs forming the basis of exercise-induced adaptive responses.

BACKGROUND: The increase in problematic substance use is a major problem in Canada and elsewhere, placing a heavy burden on health and justice system resources given a spike in drug-related offences. Thus, achievement of Sustainable Development Goal (SDG) Target 3.5 to 'Strengthen the prevention and treatment of substance abuse' is important for Canada's overall realization of the SDGs, including SDG 3 (Good Health and Wellbeing). Since 2008, Vancouver's Downtown Community Court (DCC) has pioneered an innovative partnership among the justice, health and social service systems to address individuals' needs and circumstances leading to criminal behaviour. While researchers have examined the DCC's impact on reducing recidivism, with Canada's SDG health commitments in mind, we set out to examine the ways health and the social determinants of health (SDH) are engaged and framed externally with regard to DCC functioning, as well as internally by DCC actors. We employed a multi-pronged approach analyzing (1) publicly available DCC documents, (2) print media coverage, and (3) health-related discourse and references in DCC hearings. RESULTS: The documentary analysis showed that health and the SDH are framed by the DCC as instrumental for reducing drug-related offences and improving public safety. The observation data indicate that judges use health and SDH in providing context, understanding triggers for offences and offering rationale for sentencing and management plans that connect individuals to healthcare, social and cultural services. CONCLUSIONS: Our study contributes new insights on the effectiveness of the DCC as a means to integrate justice, health and social services for improved health and community safety. The development of such community court interventions, and their impact on health and the SDH, should be reported on by Canada and other countries as a key contribution to SDG 3 achievement, as well as the fulfillment of other targets under the SDG framework that contain the SDH. Consideration should be given by Canada as to how to capture and integrate the important data generated by the DCC and other problem-solving courts into SDG reporting metrics. Certainly, the DCC advances the SDGs' underlying Leave No One Behind principle in a high-income country context.

Bovine babesiosis caused by Babesia bovis remains an important constraint for the development of cattle industries worldwide. Effective control can be achieved by vaccination with live attenuated phenotypes of the parasite. However, these vaccines have a number of drawbacks, which justifies the search for better, safer vaccines. In recent years, a number of parasite proteins with immunogenic potential have been discovered. However, there is little information on the genetic conservation of these proteins among different parasite isolates, which hinders their assessment as immunogens. The aim of the present study was to evaluate the conservation of the genes ama-1, acs-1, rap-1, trap, p0 and msa2c among five Brazilian isolates of B. bovis. Through polymerase chain reaction, genetic sequencing and bioinformatics analysis of the genes, a high degree of conservation (98-100%) was found among Brazilian isolates of B. bovis and the T2Bo isolate. Thus, these genes are worth considering as viable candidates to be included in a recombinant cocktail vaccine for cattle babesiosis caused by B. bovis.

The clinical signs of Ehrlichia canis and Anaplasma platys infection are similar, and the diagnosis of these pathogens made by stained blood smears is poor due sensibility and specificity. On the other hand, the molecular diagnosis is highly sensitive and specific and nested-PCR have been optimized for accurate diagnosis these pathogens in dogs. At the veterinary teaching hospital, whole-blood samples with EDTA were obtained from 100 dogs and smears were made from blood samples for evaluation for intracellular parasites. For each sample, DNA was extracted and submitted to nPCR analysis for detection of E. canis and A. platys. The results of stained blood smears showed 9% of the animals were positive for E. canis and 21% for A. platys. Regarding of nPCR analysis, 57 and 55% of dogs were positive for E. canis and A. platys respectively. As compared to a nested PCR, the stained blood smears revealed false-negative results for both E. canis and A. platys. The results indicate that the nPCR is highly sensitive and specific for detection of both pathogens and the molecular diagnosis could be more useful at veterinary hospital.

Babesiosis, anaplasmosis, and trypanosomosis are relevant diseases, potentially causing morbidity in cattle, leading to economic losses. Borreliosis is import as a potential zoonosis. The objective of this study was to determine, by indirect enzyme-linked immunosorbent assay (ELISA), the frequency of seropositive cattle to Babesia bigemina, B. bovis, Anaplasma marginale, Trypanosoma vivax and Borrelia burgdorferi in cattle from the Northeastern region of Pará, Brazil. Sera samples from 246 female adult cattle from municipalities of Castanhal and São Miguel do Guamá were used. Crude antigens ELISAs were used to detect antibodies to all agents, except to A. marginale, to which an indirect ELISA with recombinant major surface 1a protein (MSP1a) antigen was used. Overall frequencies of seropositive animals were: B. bigemina--99.2%; B. bovis--98.8%; A. marginale--68.3%; T. vivax--93.1% and B. burgdorferi--54.9%. The frequencies of seropositive cattle to B. bovis and B. bigemina suggest a high rate of transmission of these organisms by tick in the studied region, which can be classified as enzootically stable to these hemoprotozoans. The low frequency of seropositive cattle to A. marginale may be attributed to a lower sensitivity of the recombinant antigen ELISA utilized or a distinct rate of inoculation of this rickettsia by ticks, as compared with Babesia sp. transmission. The high frequency of seropositive cattle to T. vivax indicates that this hemoprotozoan is prevalent in herds from the Northeastern region of Pará. The rate of animal that showed homologues antibodies to B. burgdorferi indicates the presence of the tickborne spirochaetal agent in the cattle population in the studied region.

We investigated the effects of chronic administration of sertraline (SERT; approximately 20 mg kg(-1) day(-1) in drinking water), a selective serotonin reuptake inhibitor, on water and sodium intake and on plasma levels of oxytocin (OT) and vasopressin (AVP) in basal and stimulated conditions. Basal water intake was reduced in SERT-treated rats. After 24 h of water deprivation, rats treated with SERT for 21 days ingested less water than the control rats (9.7 +/- 0.5 versus 20.0 +/- 0.9 ml, respectively, at 300 min after water presentation, P < 0.0001). Subcutaneous injection of 2 m NaCl or isoproterenol evoked a lower dipsogenic response in rats treated with SERT for 21 days. Fluid and food deprivation also induced a weaker dipsogenic response in SERT-treated rats (1.6 +/- 0.5 versus 10.2 +/- 1.2 ml, at 300 min, P < 0.0001) but had no effect on saline intake. Sodium depletion induced a higher natriorexigenic response in the SERT group (5.6 +/- 1.3 versus 1.2 +/- 0.3 ml, at 300 min, P < 0.0002). Higher urinary density and lower plasma sodium levels were observed after SERT treatment. Sertraline also increased plasma levels of vasopressin and oxytocin (AVP, 2.65 +/- 0.36 versus 1.31 +/- 0.16 pg ml(-1), P < 0.005; OT, 17.16 +/- 1.06 versus 11.3 +/- 1.03 pg ml(-1), P < 0.0009, at the third week post-treatment). These data constitute the first evidence that chronic SERT treatment affects water and sodium intake in rats. These effects seem to be related to the hyponatraemia caused by the higher plasma levels of AVP and OT.
