Effects of exercise interventions on functioning and health-related quality of life following hospital discharge for recovery from critical illness: A systematic review and meta-analysis of randomized trials.

OBJECTIVE: This systematic review and meta-analysis aimed to analyze the published randomized controlled trials (RCTs) that investigated the effects of exercise interventions on functioning and health-related quality of life following hospital discharge for recovery from critical illness. DESIGN: Systematic review and meta-analysis of RCTs. DATA SOURCES: We searched PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, PEDro data base, and SciELO (from the earliest date available to January 2023) for RCTs that evaluated the effects of physical rehabilitation interventions following hospital discharge for recovery from critical illness. REVIEW METHODS: Study quality was evaluated using the PEDro Scale. Mean differences (MDs), standard MDs (SMD), and 95% confidence intervals (CIs) were calculated. RESULTS: Fourteen studies met the study criteria, including 1259 patients. Exercise interventions improved aerobic capacity SMD 0.2 (95% CI: 0.03-0.3, I2 = 0% N = 880, nine studies, high-quality evidence), and physical component score of health-related quality of life MD 3.3 (95% CI: 1.0-5.6, I2 = 57%, six studies N = 669, moderate-quality evidence). In addition, a significant reduction in depression was observed MD -1.4 (95% CI: -2.7 to -0.1, I2 = 0% N = 148, three studies, moderate-quality evidence). No serious adverse events were reported. CONCLUSION: Exercise intervention was associated with improvement of aerobic capacity, depression, and physical component score of health-related quality of life after hospital discharge for survivors of critical illness.

Short-Finned Pilot Whale Strandings Associated with Pilot Whale Morbillivirus, Brazil.

Cetacean morbillivirus (CeMV) causes illness and death in cetaceans worldwide; the CeMV strains circulating in the Southern Hemisphere are poorly known. We detected a pilot whale CeMV strain in 3 short-finned pilot whales (Globicephala macrorhynchus) stranded in Brazil during July-October 2020. Our results confirm this virus circulates in this species.

Molecular Detection and Characterization of Mycoplasma spp. in Marine Mammals, Brazil.

Mycoplasma spp. are wall-less bacteria able to infect mammals and are classified as hemotropic (hemoplasma) and nonhemotropic. In aquatic mammals, hemoplasma have been reported in California sea lions (Zalophus californianus) and river dolphins (Inia spp.). We investigated Mycoplasma spp. in blood samples of West Indian manatees (Trichechus manatus), pinnipeds (5 species), and marine cetaceans (18 species) that stranded or were undergoing rehabilitation in Brazil during 2002-2022. We detected Mycoplasma in blood of 18/130 (14.8%) cetaceans and 3/18 (16.6%) pinnipeds. All tested manatees were PCR-negative for Mycoplasma. Our findings indicate that >2 different hemoplasma species are circulating in cetaceans. The sequences from pinnipeds were similar to previously described sequences. We also detected a nonhemotropic Mycoplasma in 2 Franciscana dolphins (Pontoporia blainvillei) that might be associated with microscopic lesions. Because certain hemoplasmas can cause disease and death in immunosuppressed mammals, the bacteria could have conservation implications for already endangered aquatic mammals.

Virulence factors of Gram-negative bacteria from free-ranging Amazon river dolphins (Inia geoffrensis).

Freshwater cetaceans play a significant role as sentinel animals, providing important data on animal species and aquatic ecosystem health. They also may serve as potential reservoirs of emerging pathogens and host virulence genes in their microbiota. In this study, we evaluated virulence factors produced by Gram-negative bacteria recovered from individuals belonging to two populations of free-ranging Amazon river dolphins (Inia geoffrensis). A total of 132 isolates recovered from the oral cavity, blowhole, genital opening and rectum of 21 river dolphins, 13 from Negro River and 8 from Tapajós River, Brazil, were evaluated for the production of virulence factors, such as biofilms and exoproducts (proteases, hemolysins and siderophores), in planktonic and biofilm forms. In planktonic form, 81.1% (107/132) of the tested bacteria of free-ranging Amazon river dolphins were able to produce virulence factors, with 44/132 (33.4%), 65/132 (49,2%) and 54/132 (40,9%) positive for protease, hemolysin and siderophore production, respectively. Overall, 57/132 (43.2%) of the isolates produced biofilms and, under this form of growth, 66/132 (50%), 88/132 (66.7%) and 80/132 (60.6%) of the isolates were positive for protease, hemolysin and siderophore production. In general, the isolates showed a higher release of exoproducts in biofilm than in planktonic form (P < 0.001). The present findings show that Amazon river dolphins harbor potentially pathogenic bacteria in their microbiota, highlighting the importance of monitoring the micro-organisms from wild animals, as they may emerge as pathogens for humans and other animals.

Using Object Detection Technology to Identify Defects in Clothing for Blind People.

Blind people often encounter challenges in managing their clothing, specifically in identifying defects such as stains or holes. With the progress of the computer vision field, it is crucial to minimize these limitations as much as possible to assist blind people with selecting appropriate clothing. Therefore, the objective of this paper is to use object detection technology to categorize and detect stains on garments. The defect detection system proposed in this study relies on the You Only Look Once (YOLO) architecture, which is a single-stage object detector that is well-suited for automated inspection tasks. The authors collected a dataset of clothing with defects and used it to train and evaluate the proposed system. The methodology used for the optimization of the defect detection system was based on three main components: (i) increasing the dataset with new defects, illumination conditions, and backgrounds, (ii) introducing data augmentation, and (iii) introducing defect classification. The authors compared and evaluated three different YOLOv5 models. The results of this study demonstrate that the proposed approach is effective and suitable for different challenging defect detection conditions, showing high average precision (AP) values, and paving the way for a mobile application to be accessible for the blind community.

Human Exposure to Non-Ionizing Radiation from Indoor Distributed Antenna System: Shopping Mall Measurement Analysis.

It is crucial to monitor the levels of Non-Ionizing Radiation (NIR) to which the general population may be exposed and compare them to the limits defined in the current standards, in view of the rapid rise of communication services and the prospects of a connected society. A high number of people visits shopping malls and since these locations usually have several indoor antennas close to the public, it is therefore a kind of place that must be evaluated. Thus, this work presents measurements of the electric field in a shopping mall located in Natal, Brazil. We proposed a set of six measurement points, following two criteria: places with great the flow of people and the presence of one or more Distributed Antenna System (DAS), co-sited or not with WiFi access points. Results are presented and discussed in terms of the distance to DAS (conditions: near and far) and flow density of people in the mall (scenarios: low and high number of people). The highest peaks of electric field measured were 1.96 and 3.26 V/m, respectively corresponding to 5% and 8% of the limits defined by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and the Brazilian National Telecommunication Agency (ANATEL).

Hemotropic Mycoplasma spp. in Aquatic Mammals, Amazon Basin, Brazil.

Hemotropic Mycoplasma spp. (hemoplasmas) are uncultivable bacteria that infect mammals, including humans. We detected a potentially novel hemoplasma species in blood samples from wild river dolphins in the Amazon River Basin, Brazil. Further investigation could determine pathogenicity and zoonotic potential of the detected hemoplasma.

Effect of neuromuscular electrical stimulation on functional exercise capacity in patients undergoing cardiac surgery: A randomized clinical trial.

OBJECTIVE: To evaluate the effects of neuromuscular electrical stimulation on functional capacity of patients in the immediate postoperative period of cardiac surgery. DESIGN: A prospective, randomized controlled trial. SETTING: A cardiac surgery specialist hospital in Aracaju, Sergipe, Brazil. Subjects: Patients in the postoperative period of cardiac surgery. INTERVENTION: The control group received the conventional physiotherapy and the intervention group received neuromuscular electrical stimulation of the rectus femoris and gastrocnemius muscles bilaterally, applied for 60 min, twice a day for up to 10 sessions per patient, in the immediate postoperative period until postoperative day 5. MAIN MEASURES: The primary outcome was the distance walked, which was evaluated using the 6-min walk test on postoperative day 5. Secondary outcomes were gait speed, lactate levels, muscle strength, electromyographic activity of the rectus femoris and Functional Independence Measure, some of them evaluated on preoperative and postoperative period. RESULTS: Of 132 eligible patients, 88 patients were included and randomly allocated in two groups, and 45 patients were included in the analysis. No significant difference was found on the distance walked (p = 0.650) between patients allocated in intervention group (239.06 ± 88.55) and control group (254.43 ± 116.67) as well as gait speed (p = 0.363), lactate levels (p = 0.302), knee extensor strength (p = 0.117), handgrip strength (p = 0.882), global muscle strength (p = 0.104), electromyographic activity (p = 0.179) and Functional Independence Measure (p = 0.059). CONCLUSIONS: Although the effects are still uncertain, the use of neuromuscular electrical stimulation carried out in five days didn't present any benefit on functional capacity of patients in the immediate postoperative period of cardiac surgery.

Use of the FLOTAC technique as a new coproparasitological diagnostic method in aquatic mammals and comparison with traditional methods.

The inadequate choice of a diagnostic method or the option for techniques that have low sensitivity and specificity may limit the diagnosis of parasitic agents that affect aquatic mammals. The aim of this study was to evaluate the performance of the FLOTAC technique and compare it with three traditional methods (Willis, sedimentation and centrifugation- flotation) used in the diagnosis of gastrointestinal parasites in aquatic mammals. For this, 129 fecal samples from 12 species were collected. Each sample was submitted to laboratory processing using the Willis, Hoffman techniques, Faust method and FLOTAC. Sensitivity, specificity, real prevalence, estimated prevalence, positive predictive value, negative predictive value, correct classification (accuracy) and incorrect classification were evaluated to compare the different diagnostic methods. The highest frequency of positive samples occurred using FLOTAC (46.51%), compared to Hoffman (23.25%), Faust (10.07%) and Willis techniques (6.97%). In the samples analyzed, the occurrence of Strongylidae eggs and Eimeriidae oocysts was frequently observed. The FLOTAC technique proved to be the most appropriate technique and due to its efficacy, is strongly recommended for coproparasitological evaluations in aquatic mammals.

Effect of ivabradine on exercise capacity in individuals with heart failure with preserved ejection fraction.

The prevalence of heart failure with preserved ejection fraction (HFpEF) is about 30-75% of the patients living with heart failure. A hallmark symptom of these patients is exercise intolerance. Ivabradine can, eventually, increase exercise capacity by heart rate control. However, clinical trials show conflicting results about the effects of ivabradine on exercise capacity, an important prognostic variable. The aim of this study was to investigate the effects of ivabradine on exercise capacity in individuals with HFpEF. This study was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and supplemented by guidance from the Cochrane Collaboration Handbook for Systematic Reviews of Interventions. For the meta-analysis, a forest plot was used to graphically present the effect sizes and the 95% CIs. Four randomized controlled trials were included. Ivabradine did not change exercise capacity expressed by peak VO2 and 6MWT (MD = 0.8; 95% CI - 2.5 to 4.3; P = 0.62) (Fig. 4a). In our secondary analysis, the ivabradine group showed a significant resting HR reduction when compared with placebo (MD = - 13.2; 95% CI - 16.6 to -9.8; P < 0.00001) and ivabradine showed increased values of E/e' ratio compared with placebo (MD = 0.8; 95% CI 0.0 to 1.6; P = 0.04). Current available evidence suggests that there is no effect of ivabradine on exercise capacity in patients with HFpEF. Also, questions about negative effects on E/e' values and adverse events associated with ivabradine treatment need to be considered in future studies.

Effect of Aerobic Exercise on Peak Oxygen Consumption, VE/VCO2 Slope, and Health-Related Quality of Life in Patients with Heart Failure with Preserved Left Ventricular Ejection Fraction: a Systematic Review and Meta-Analysis.

PURPOSE OF REVIEW: The aim of this study was to determine the effects of aerobic exercise on peak oxygen uptake (peak VO2), minute ventilation/carbon dioxide production (VE/VCO2 slope), and health-related quality of life (HRQoL) among patients with heart failure (HF) and preserved ejection fraction (HFpEF). RECENT FINDINGS: We conducted a Cochrane Library, MEDLINE/PubMed, Physiotherapy Evidence Database, and SciELO search (from 1985 to May 2019) for randomized controlled trials that evaluated the effects of aerobic exercise in HFpEF patients. We calculated the mean differences (MD) and 95% confidence interval (CI). Ten intervention studies were included providing a total of 399 patients. Compared with control, aerobic exercise resulted in improvement in peak VO2 MD 1.9 mL kg-1 min-1 (95% CI 1.3 to 2.5; N = 314) and HRQoL measured by Minnesota Living with Heart Failure MD 5.4 (95% CI - 10.5 to - 0.2; N = 256). No significant difference in VE/VCO2 slope was found between participants in the aerobic exercise group and the control group. The quality of evidence for peak VO2 and HRQoL was assessed as being moderate. Aerobic exercise moderately improves peak VO2 and HRQoL and should be considered a strategy of rehabilitation of HFpEF individuals.

A hybrid swarm of manatees along the Guianas coastline, a peculiar environment under the influence of the Amazon River plume.

The West Indian (Trichechus manatus) and Amazonian (T. inunguis) manatees have a sympatric occurrence at the mouth of the Amazon River. A result of this interspecific encounter is the occurrence of hybrids, which are frequently found along the coasts of Amapá state in Brazil, French Guiana and Guyana. Here we present new genetic evidence indicating the occurrence of a hybrid swarm along the Guianas Shield coastline, which is an interspecific hybrid zone that also separates T. manatus populations located east (Brazil) and west (Caribbean, Gulf of Mexico, Florida and Antilles). In addition, we suggest that this hybrid population occupies a peculiar mangrove-rich environment under strong influence of the Amazon River plume, which requires an independent management and should be considered a special conservation area.

The impact of high-intensity inspiratory muscle training on exercise capacity and inspiratory muscle strength in heart failure with reduced ejection fraction: a systematic review and meta-analysis.

OBJECTIVE:: Inspiratory muscle training (IMT) improves prognostic clinical variables in patients with heart failure. However, the optimal intensity for increasing those outcomes remains unclear. Thus, we aimed to determine whether high-intensity inspiratory muscle training (HIIMT) improves exercise capacity and respiratory muscle strength in patients with heart failure with reduced ejection fraction (HFrEF). METHODS:: We searched for randomized controlled clinical trials at MEDLINE, the Cochrane Central Register of Controlled Trials, the Physiotherapy Evidence Database, SciELO and CINAHL from the earliest date available to May 2018. Primary studies on HIIMT against low-intensity IMT or sham-IMT that evaluated exercise capacity and inspiratory muscle strength were included. Two independent reviewers evaluated the eligibility of studies retrieved from the databases. Disagreements were resolved by discussion or by a third reviewer. Weighted mean difference (WMD), standardized mean difference (SMD) and 95% confidence interval (CI) were estimated by random effect models. RESULTS:: Five studies met the eligibility criteria (138 patients). HIIMT improved VO2peak (WMD 2.65 mL kg-1 min-1; 95% CI: 2.2 to 3.1 mL kg-1 min-1), walking tests (SMD 1.71; 95% CI: 0.83 to 2.59) and maximal inspiratory pressure (WMD 16.63 cmH2O; 95% CI: 10.34 to 22.91 cmH2O). The estimate for potential risks of adverse events was not performed because of the low prevalence of reports in primary studies. CONCLUSION:: HIIMT seems to be a useful strategy for improving exercise capacity and inspiratory muscle strength in HFrEF patients.

Survey of Brucella spp. and Leptospira spp. antibodies in cetaceans and manatees of the Amazon basin and Atlantic Ocean, Brazil.

Aquatic mammals can act as sentinels of emerging and resurging pathogens in the environment. Brucella spp. and Leptospira spp. are 2 zoonotic pathogens relevant to aquatic mammals, and their detection can be used to assess pathogen exposure. In this study, serum from 84 individuals-63 cetaceans (families Iniidae, n = 37; Delphinidae, n = 22; and Kogiidae, n = 4) and 21 West Indian manatees Trichechus manatus-was tested by the Rose Bengal Test (RBT) and a commercial competitive enzyme-linked immunosorbent assay (c-ELISA) for detecting Brucella spp. antibodies, and the microscopic agglutination test (MAT) for screening Leptospira spp. exposure. Overall, 4.8% (3/63) of cetaceans were positive by RBT and 15.9% (10/63) by c-ELISA for Brucella spp. Serum from 8 c-ELISA positive cetaceans (with available serum) was further tested via serum agglutination test (SAT) and 1 individual was positive. c-ELISA was more sensitive than RBT. Exposure to Brucella spp. was found in 5 cetacean species: Clymene dolphin Stenella clymene, short-finned pilot whale Globicephala macrorhynchus, pygmy killer whale Feresa attenuata, melon-headed whale Peponocephala electra and Atlantic bottlenose dolphin Tursiops truncatus in the Atlantic Ocean, Brazil, expanding the range of known Brucella seropositive aquatic hosts. No evidence of Brucella spp. exposure was found in Iniidae and Kogiidae odontocetes and manatees. Antibodies against Leptospira spp. were not detected in cetaceans and sirenians by MAT. These results contribute to the evaluation of different Brucella spp. serological methods in cetaceans and manatees and highlight the epidemiology of zoonotic pathogens in aquatic mammals of the southwestern Atlantic Ocean and the Amazon basin.

Pre- and postoperative inspiratory muscle training in patients undergoing cardiac surgery: systematic review and meta-analysis.

OBJECTIVE: To determine the effects of pre- and postoperative inspiratory muscle training on length of postoperative hospital stay and pulmonary function in patients undergoing cardiac surgery. DESIGN AND METHODS: We conducted a systematic search using databases (MEDLINE, CINAHL, EMBASE, PEDro and the Cochrane) to find controlled trials evaluating the effects of pre- and postoperative inspiratory muscle training. RESULTS: Eight studies fulfilled the inclusion criteria. Four were about preoperative inspiratory muscle training (416 patients), three about postoperative inspiratory muscle training (115 patients) and one study about pre- and postoperative inspiratory muscle training (43 patients). Preoperative inspiratory muscle training resulted in improvement in: Reduction in length of postoperative hospital stay of -2 days (95% CI -3.4, -0.7, N = 302), inspiratory pressure of 16.7 cm H2O (95% CI 13.8, 19.5, N = 386), forced expiratory volume in one second of 3% predicted (95% CI 0.1, 6, N = 140), forced vital capacity of 4.6% predicted (95% CI 1.9, 7.4, N = 140). Patients that received preoperative training had an inspiratory muscle training reduced risk of postoperative pulmonary complications, (RR = 0.6; 95% CI 0.5 to 0.8; P = 0.0004, N = 386). Postoperative inspiratory muscle training resulted in improvement in inspiratory pressure of 16.5 cm H2O (95% CI 4.9, 27.8, N = 115), and tidal volume of 185 ml (95% CI 19.7, 349.8, N = 85). CONCLUSION: Pre- and postoperative inspiratory muscle training showed to be a beneficial intervention in the treatment of patients undergoing cardiac surgery.

Addition of non-invasive ventilatory support to combined aerobic and resistance training improves dyspnea and quality of life in heart failure patients: a randomized controlled trial.

OBJECTIVE: To test the hypothesis that combined aerobic and resistance training and non-invasive ventilatory support result in additional benefits compared with combined aerobic and resistance training alone in heart failure patients. DESIGN: A randomized, single-blind, controlled study. SETTING: Cardiac rehabilitation center. PARTICIPANTS: A total of 46 patients with New York Heart Association class II/III heart failure were randomly assigned to a 10-week program of combined aerobic and resistance training, plus non-invasive ventilatory support ( n = 23) or combined aerobic and resistance training alone ( n = 23). METHODS: Before and after intervention, results for the following were obtained: 6-minute walk test, forced vital capacity, forced expiratory volume at one second, maximal inspiratory muscle pressure, and maximal expiratory muscle pressure, with evaluation of dyspnea by the London Chest Activity of Daily Living scale, and quality of life with the Minnesota Living With Heart Failure questionnaire. RESULTS: Of the 46 included patients, 40 completed the protocol. The combined aerobic and resistance training plus non-invasive ventilatory support, as compared with combined aerobic and resistance training alone, resulted in significantly greater benefit for dyspnea (mean change: 4.8 vs. 1.3, p = 0.004), and quality of life (mean change: 19.3 vs. 6.8, p = 0.017 ). In both groups, the 6-minute walk test improved significantly (mean change: 45.7 vs. 44.1, p = 0.924), but without a statistically significant difference. CONCLUSION: Non-invasive ventilatory support combined with combined aerobic and resistance training provides additional benefits for dyspnea and quality of life in moderate heart failure patients. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02384798. Registered 03 April 2015.

Effects of the FIFA 11 training program on injury prevention and performance in football players: a systematic review and meta-analysis.

OBJECTIVE: To investigate the effects of FIFA 11 training on injury prevention and performance in football players. DESIGN AND METHODS: Systematic review and meta-analysis. We conducted a systematic search using four databases (CINAHL, Cochrane Library, EMBASE, and PubMed) to find controlled trials evaluating the effects of FIFA 11 on injury prevention and performance among football players. Weighted mean differences, standard mean differences, risk ratios, and 95% confidence intervals were calculated, and heterogeneity was assessed using the I2 test. RESULTS: We analyzed 11 trials, including 4700 participants. FIFA 11 resulted in a significant reduction in injury risk (risk ratio = 0.69; 95% confidence interval, 0.49-0.98; P = 0.02) and improvements in dynamic balance (weighted mean difference = 2.68; 95% confidence interval, 0.44-4.92; P = 0.02) and agility (standard mean difference = -0.36; 95% confidence interval, 0.70-0.02; P = 0.04). The meta-analysis indicated a non-significant improvement in jump height (standard mean difference = 0.25; 95% confidence interval, 0.08-0.59; P = 0.14) and running sprint (standard mean difference = -0.24; 95% confidence interval, 0.58-0.10; P = 0.17) in the FIFA 11 group. CONCLUSIONS: FIFA 11 can be considered as a tool to reduce the risk of injury. It may improve dynamic balance and agility and can be considered for inclusion in the training of football players.

Cryptosporidium spp. and Giardia sp. in aquatic mammals in northern and northeastern Brazil.

Cryptosporidium and Giardia are protozoans that can infect humans and wild and domestic animals. Due to the growing importance of diseases caused by protozoan parasites in aquatic species, we aimed to evaluate the frequency of infection by Cryptosporidium spp. and Giardia sp. in aquatic and marine mammals in the northern and northeastern regions of Brazil. We collected 553 fecal samples from 15 species of wild-ranging and captive aquatic mammals in northern and northeastern Brazil. All samples were analyzed by the Kinyoun technique for identification of Cryptosporidium spp. oocysts. Giardia sp. cysts were identified by means of the centrifugal-flotation technique in zinc sulfate solution. Subsequently, all samples were submitted for direct immunofluorescence testing. The overall frequency of infection was 15.55% (86/553) for Cryptosporidium spp. and 9.04% (50/553) for Giardia sp. The presence of Cryptosporidium spp. was detected in samples from 5 species: neotropical river otter Lontra longicaudis (15.28%), giant otter Pteronura brasiliensis (41.66%), Guiana dolphin Sotalia guianensis (9.67%), Amazonian manatee Trichechus inunguis (16.03%), and Antillean manatee T. manatus (13.79%). Giardia sp. was identified in L. longicaudis (9.23%), P. brasiliensis (29.16%), pygmy sperm whale Kogia breviceps (100%), dwarf sperm whale K. sima (25%), S. guianensis (9.67%), T. inunguis (3.81%), and T. manatus (10.34%). This is the first report of Cryptosporidium spp. in L. longicaudis, P. brasiliensis, and S. guianensis, while the occurrence of Giardia sp., in addition to the 2 otter species, was also identified in manatees, thus extending the number of hosts susceptible to these parasitic agents.

Integrative taxonomy of anisakid nematodes in stranded cetaceans from Brazilian waters: an update on parasite's hosts and geographical records.

Anisakidae are represented mainly by species of Anisakis Dujardin, 1845, Pseudoterranova Krabbe, 1878, and Contracaecum Railliet and Henry, 1913. Integrative taxonomy, based on morphological and genetic approaches, can provide a precise identification of species, increasing the knowledge of their systematics, biology, and evolution. In this study, integrative taxonomy was applied in order to identify, at generic and/or specific taxonomic level, 245 anisakids from 63 cetaceans of 12 different species, which stranded in the Brazilian coast. Parasites from nine hosts were preserved by freezing and, from 54 hosts, were fixed in 70% ethanol (n = 43) or alcohol-formalin-acetic (n = 11) for a period varying from 6 to 19 years. The morphological analysis allowed the identification of 171 specimens at genus level: 120 as Anisakis sp. clade I, 47 as Anisakis sp. clade II, and four as Pseudoterranova sp. From those 15, specimens were identified at species level, seven as Anisakis typica, seven as Anisakis paggiae and one as Anisakis brevispiculata. Moreover, 74 specimens were identified as belonging to Anisakidae family. The genetic analysis based on cox2 gene allowed the identification/confirmation of Anisakis typica (n = 33), Anisakis paggiae (n = 1), and for the first time in the Brazilian coast, Anisakis brevispiculata (n = 4) and Anisakis ziphidarum (n = 1). Additionally, a probably new Anisakis species, genetically close to A. paggiae, is reported infecting a dwarf sperm whale. The results clearly indicated that the preservation of nematodes influenced significantly on the level of taxonomic definition, in both morphological and, mainly, genetic analyses. Pseudoterranova sp. was identified for the first time in the spinner dolphin, Stenella longirostris. The detection of nine A. paggiae specimens, in three Kogia breviceps animals, substantiates the austral occurrence of this species. The identification of A. brevispiculata in Kogia sima and K. breviceps confirms Kogiidae whales as their most common hosts. Anisakis typica was corroborated as a generalist species, the most widely distributed in the Brazilian coast, infecting a broad variety of Delphinidae and Kogiidae, with two new geographical records in Stenella frontalis and Lagenodelphis hosei. The study showed a new scenery of parasite diversity of marine anisakids, updating the Anisakis species distribution.
