RESUMO

Hesperidin (HSD) is a natural compound with antioxidant potential. On the other hand, chronic stress had been linked to impaired cognitive functions as it affects many neurotransmitters and brain regions such as the hippocampus. The current study was conducted to examine the effect of HSD on learning and memory after chronic mild stress. Albino Wistar rats were subjected to chronic mild stress with HSD administered as supplements. HSD was found to decrease hippocampal amyloid beta and malondialdehyde levels, in addition, to preserve cognitive functions together with preserving hippocampus histological architecture. In conclusion, the present study sheds the light on the potential of HSD to ameliorate the deleterious effects of chronic mild stress on cognitive functions through brain-derived neurotrophic factor enhancement and reduction in Aß formation in addition to activation of the antioxidant pathway.

RESUMO

Virulent pathotypes of E. coli seriously affect the livestock regarding the misuse of antibiotics. All 180 samples collected from cow's environment and dairy shops in Qena, Egypt were serologically and molecularly positive for coliforms. Enteropathogenic E. coli (EPEC), Shiga toxin-producing E. coli (STEC), Enteroinvasive E. coli (EIEC) and Enterotoxigenic E. coli (ETEC) pathotypes were isolated from water and milk-related samples. STEC serogroups O26, O55, O111, O113, O145 were also recovered. The non-O157 STEC serotypes were recovered from human diarrheagenic patients contacting cattle or consuming contaminated water/milk products. BlaCTX-M and blaTEM genes were detected in 25.5% and 100%, respectively. Disinfectants and algal extracts, identified by GC-MS, were evaluated in vitro for antibacterial activities. TH4+® disinfectant and methanol extract of Turbinaria decurrens reduced E. coli at 13 log10 at 1.5% and 3 mg/ml concentrations, respectively. Ag-NPs/T. decurrens showed 8-9 log10 reduction at concentration of 1.6 × 105 NPs/ml. Examined water sources, milk and milk products were potential reservoirs for virulent antibiotic-resistant E.coli which may impose animal and public health threats.Abbreviations: APEC: Avian pathogenic E. coli; blaCTX-M: ß-lactamase inhibitors-Cefotaximase gene; blaTEM: ß-lactamase inhibitors-Temoneira gene; CFU: Colony-forming unit; DAEC: Diffusely adherent E. coli; DEC: Diarrheagenic Escherichia coli; DEMSO: Dimethyl sulfoxide; eaeA: Intimin or E. coli attaching gene; EAEC: Enteroaggregative E. coli; EHEC: Enterohemorrhagic E. coli; EIEC: Enteroinvasive E. coli; EOSQC: Egyptian Organization for Standardization and Quality Control; EPEC: Enteropathogenic E. coli; ETEC: Enterotoxigenic E. coli; ExPEC: Extra-intestinal pathogenic E. coli; GC-MS: Gas chromatography-mass spectrometry technique; hly: Hemolysin gene; STEC: Shiga like producing E. coli; stx1: Shiga-toxin 1 gene; ESBLs: Extended-spectrum beta-lactamases.

RESUMO

Coronavirus disease 2019 (COVID-19) is a recent epidemic disease caused by severe acute respiratory syndrome virus type 2 (SARS-CoV-2). In pregnancy, SARS-Cov-2 infection creates additional alarm due to concerns regarding the potential for transmission from the mother to the baby during both the antenatal and postpartum times. In general, breastfeeding is seldom disallowed because of infection of the mother. However, there are few exceptions with regards to certain infectious organisms with established transmission evidence from mother to infant and the link of infection of a newborn with significant morbidity and mortality. It is confirmed that pregnant women can become infected with SARS-CoV-2, although the debate on the possible vertical transmission of SARS-CoV-2 infection during pregnancy is still open. In this regard, the literature is still poor. On the contrary, the information on the safety of breastfeeding even during infections seems reassuring when the mother takes the necessary precautions. However, there are still answered questions regarding the precautions to be taken during breastfeeding by COVID-19 patients. This paper reviews the existing answers to these and many other questions. This review therefore presents a summary of the present-day understanding of infection with SARS-CoV-2 and discusses the answers around the maternal transmission of COVID-19 and the potential threat of breastfeeding to babies born to infected pregnant mothers. In conclusion, intrauterine transmission of SARS-CoV-2 infection is less likely to occur during pregnancy. Most studies suggest that COVID-19 is not transmitted through breast milk. Correspondingly, COVID-19-infected neonates might acquire the infection via the respiratory route because of the postnatal contact with the mother rather than during the prenatal period. International organizations encourage breastfeeding regardless of the COVID-19 status of the mother or child as long as proper hygienic and safety measures are adhered to so as to minimize the chance of infant infection by droplets and direct contact with the infected mother. Pasteurized donor human milk or infant formula as supplemental feeding can be quite beneficial in the case of mother-infant separation till breastfeeding is safe.

RESUMO

Malathion (MA) is a widely used pesticide in agriculture. It can cause toxicity in different organs of the body. Rosmarinic acid (RO) is found in rosemary extract that can be absorbed through gastrointestinal tract mucosa with potent antioxidant, and anti-inflammatory potential. The current study is designed to investigate the potential of RO to protect the lung after MA administration. Forty albino rats were allocated equally to four groups. C-group received corn oil. RO-group received RO orally. MA-group received MA. MA-RO-group received RO in addition to MA. After three weeks the lungs were dissected for histopathological and biochemical investigations. MA-group showed manifestations of severe inflammation with inflammatory cells infiltration in the lung. MA-RO-group showed limited inflammatory cell infiltration. C-group and RO-group appeared with weak anti-survivin immunoreactivity. MA-group showed strong positive immunoreactivity. The reactivity was weakly positive in MA-RO-group. MA-group showed a significant decrease in SP-D gene expression in comparison to the C-group, in addition, MA-RO-group showed a significant increase in SP-D expression. In conclusion, the current study approves that oral administration of MA causes lung injury as it has inflammatory effects, caused by oxidative stress and reports the potential of RO to protect lung tissue against toxic effects of MA through its anti-inflammatory, antioxidant, and anti-apoptotic potential.

RESUMO

Di-isononyl phthalate (DIP) is considered a high molecular-weight subtype of phthalates that are commonly used and could easily affect the gastrointestinal tract (GIT). Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are the main active components of fish oil (FO), and their anti-inflammatory potential was previously documented. The current study was designed to investigate the protective potential of fish oil against the impacts of DIP exposure on the colon of albino Wistar rats. Sixty albino Wistar rats were divided into Control group received corn oil for ten days. Di-isononyl phthalate treated group received DIP. Di-isononyl phthalate + fish oil treated group received both DIP and FO. FO was found to preserve the histological architecture, tight junction and cell cycle of the colon. In conclusion, the current study provided an evidence that FO has a protective potential against DIP further examinations to be done to fully understand the molecular basis of this potential as a step for further clinical applications.

RESUMO

Glutamate (Gt) neurotoxicity contributes to a wide spectrum of neurological conditions. Loss of glutamate transporters leads to intracellular Gt accumulation. Amantadin (AMn) is a non-competitive N-methyl-D-aspartate (NMDA) antagonist that can partially inhibit Gt transporters and influence protein phosphatase 2A subunit B (PP-2A-B) activity. Herein, we investigate the potential of AMn administered in the early life stages to reverse the Gt-induced changes in the cerebral cortex in the rat model. We report that AMn can reverse Gt-induced structural changes in the brain cortex and increase PP-2A activity. Additionally, PP-2A-B activity in the AMn + Gt-treated group was comparable to controls. Moreover, administration of AMn leads to a decrease of apoptotic index in the Gt-treated individuals. We suggest that severe histopathological changes observed in Gt group could be attributed to the decreased PP-2A expression causing an imbalance between phosphatase and protein kinase activities and leading to a strong positive TUNEL reaction. We provide a short summary of the current state of knowledge regarding the role of PP-2A-B in the Gt-induced neurotoxicity and AMn treatment and discuss the potential of amantadine as a potential therapeutic agent.

RESUMO

Acute kidney injury (AKI) is a sudden insult of the kidney that happens within a short period of time, which is associated with poor prognosis in diabetic patients with myocardial infarction (MI). Subclinical AKI is a condition in which tubular damage biomarkers [Neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1(KIM-1)] are positive even in the absence of elevated serum creatinine. Recent studies reported that SGLT-2 inhibitors could protect against subclinical AKI in diabetic patients by elevating the level of ß-Hydroxybutyric acid (ßOHB). This study aims to examine the reno-protective potential of empagliflozin (EMPA) against MI associated AKI in diabetic rats. Eighty Albino Wistar rats were divided into: (1) nondiabetic sham group (CS), (2) nondiabetic + myocardial infarction group (CM), (3) diabetic + myocardial infarction group (DM) and (4) diabetic + myocardial infarction + empagliflozin group (DME). At the end of the experiment, blood samples and kidneys were collected for biochemical analysis, histopathological, and immunohistochemical studies. After induction of myocardial infarction, there was a significant decrease in serum creatinine and NGAL levels in DME. After EMPA administration, mesangial matrix index and glomerular area were lowered in DME if compared to DM group. As a marker for tubular injury, we used anti-NGAL and anti-KIM-1 immunohistochemistry. Strong positive reaction was noticed in DM group if compared to DME group which showed weak positive reaction. Levels of renal mRNAs [NGAL; KIM-1; Nox-2,4; TLR-2,4; MyD88; TNF- α and IL-1 ß, 18] in DME group were reduced significantly compared to DM group. In conclusion, empagliflozin can protect against subclinical acute kidney injury in diabetic albino Wistar rats after myocardial infarction induction, which could improve the clinical outcome of SGLT-2 inhibitors in diabetic patients.

RESUMO

BACKGROUND: Prostate gland is an exocrine gland that could be affected by various pathological conditions. Benign prostatic hyperplasia (BPH) is an age-dependent medical condition caused by increased activity of 5α-reductase enzyme (5α-R). Medical treatment by finasteride is considered during treatment, but it has unavoidable side effects. Hence, there is an increasing need to use natural ingredients for BPH treatment. Gingerol oil (ginger extract) is transferred by heating into zingerone. Recent studies reported the effect of zingerone on prostate cancer cells. AIMS AND OBJECTIVES: The aim of the present research is to investigate the protective effect of zingerone against BPH. MATERIALS AND METHODS: Sixty male Albino Wistar rats were divided into three groups: control group, prostatic hyperplasia group treated with saline, and prostatic hyperplasia group treated with zingerone (PH-Z-G). At day 28, all rats were sacrificed, epididymis and prostate samples were collected for histopathological examination and Western blotting for androgen receptors (ARs) proteins and steroid 5 alpha-reductase 1 (SRD5A1). Human RWPE-1 prostatic cell line was assessed for viability and cycle after treated with zingerone 500 µg/day for 10 days. RESULTS: PH-S group showed significant (P < 0.05) thickening of connective tissue septa associated with narrowing of acinar lumen. PH-Z group showed regain of the normal histological feature. SRD5A1 and AR expression was significantly (P < 0.05) reduced in PH-Z group in comparison with PH-S group. Cell line proliferation was significantly reduced after application of zingerone with G2/M cell cycle arrest. CONCLUSION: Our results showed that natural herbal zingerone decreased the prostatic tissue levels of (5α reductase and AR) in rat BPH model, which could be a promising herbal medicine for BPH treatment. Further human clinical trials are required.

RESUMO

BACKGROUND: Non-bacterial thrombotic endocarditis (NBTE) is a paraneoplastic phenomenon with sterile vegetations. It is associated with adenocarcinoma and can shower emboli, which can be the presenting symptom. CASE PRESENTATION: A 44-year-old woman with adenocarcinoma of the lung presented with chest pain, left hand weakness, and ataxia due to repeated embolic showering from NBTE to the central nervous system (CNS) and spleen. CONCLUSION: NBTE is a rare condition that should be on the differential diagnosis in patients with culture-negative endocarditis and a history of adenocarcinoma. LEARNING POINTS: Differentiating non-bacterial thrombotic endocarditis (NBTE) from infective endocarditis can be a diagnostic challenge due to slow growing organisms; laboratory findings that suggest NBTE include the lack of leucocytosis, normal C-reactive protein, negative blood culture sets, and positive antiphospholipid antibodies.Serial transesophageal echocardiogram (TEE) should be performed if suspicion of valvular vegetations is high despite the initial TEE showing no vegetations.The mainstay treatment of NBTE is anticoagulation and addressing the underlying condition.

RESUMO

Drugs that are commonly used in poultry farms can potentially cause a detrimental effect on meat consumers as a result of chemical residues. Therefore, seeking a natural alternative is crucial for the health of the consumers. The egg yolk immunoglobulin Y (IgY) is a promising natural replacement for antibiotics in the broilers' diet. There is a scarce focus on the influence of probiotics and IgY on the quality and the nutritive values of broiler meat and whether it can efficiently displace the anti-microbial power of antibiotics. Herein we used 40 Ross chicks (1.2 ± 0.43 days old) and separated them into four groups with variant feed additives (basal diet "control," probiotic, IgY, and probiotic + IgY). Our findings showed that the combination of probiotic and IgY supplementation enhanced the carcass quality traits and decreased the pH values that could retard spoilage due to bacteria and improve shelf life and meat quality. The same group also achieved a significant reduction in thiobarbituric acid value, indicating an improvement of meat quality. Moreover, color, shear force, water holding capacity, and cooking loss were most acceptable in broiler meat supplemented with IgY, which confirmed the highest carcass quality. Notably, the weight gain in the combination group has been greatly increased. Also, the protein percentage was the highest (22.26 ± 0.29, P < 0.001) in this combined supplementation group, which revealed the highest nutritive values. Staphylococcus aureus and Escherichia coli could not be detected in the meat of the probiotics group and/or in the combined treatment group. Interestingly, the IgY group showed an evidence of the killing power (log colony-forming units per milliliter) of S. aureus and Listeria monocytogenes at 1,500 µg/ml. Our findings, in vitro as well as in vivo, revealed that the combination group had antimicrobial bioactivity and enhanced the chickens' immunity. Therefore, IgY, a novel trend of feed additives, can be used to limit drugs. Additionally, the mortality percentage recorded was zero in all groups that received feed supplementation, while the combination group reached the best financial advantages. We concluded that feeding IgY powder with probiotic is a frontier to improve the productivity, immunity, and meat quality of broilers.

RESUMO

OBJECTIVE: The purpose of this study was to measure the mean concentrations of heavy metals including aluminum (Al), arsenic, nickel (Ni), mercury, lead (Pb), and cadmium (Cd) and to assess the health hazards due to the exposure of cattle/human population to a distinct or the mixture of heavy metals through various sources. MATERIALS AND METHODS: A total of 180 samples including water sources, animal feed, and raw cows' milk from rural regions in Qena, Egypt, were examined using the inductively coupled plasma emission spectrometer (ICP; iCAP 6200). RESULTS: The data highlighted heavy metal pollution with variable concentrations among most of the investigated regions. All concentrations of Al, Ni, and Cd detected in the feeding stuff showed a strong correlation to their respective levels in milk rather than those detected in water (R 2= 0.072 vs. 0.039, 0.13 vs. 0.10, and 0.46 vs. 0.014, respectively) (p < 0.05). Anisocytosis and poikilocytosis with a tendency to rouleaux formation were evident, and basophilic stippling was a pathognomic indicator for heavy metal toxicity, especially Pb. Leukopenia and macrocytic anemia were shown in 50% and 65% of examined cattle, respectively. The target hazard quotients values were more than one (>1) for all heavy metals from water intake for both children and adults and Al and Cd in milk for children, and the hazard index values were indicated higher for noncarcinogenic health hazards. The target cancer risk values predispose people in the surveyed villages to higher cancerous risks due to exposures to the mixture of heavy metal through the consumption of water and milk. CONCLUSION: The bioaccumulation and transmission of heavy metal mixtures from water sources and feeding material have detrimental influences on milk pollution and cattle health which seem to be a serious issue affecting public health in those rural communities.

RESUMO

OBJECTIVES: To evaluate the effect of 3 different time durations of sustained end-range cervical rotation during static stretching exercises on the hemodynamics of the vertebral artery. METHODS: This observational study used Doppler ultrasonography to measure the average vertebral artery hemodynamics at the sustained end-range cervical rotation after 3 time durations of static stretching exercise: 10 seconds, 30 seconds, and 60 seconds. The sustained end-range cervical rotation was applied to 30 asymptomatic male participants. RESULTS: The peak systolic velocity 35.2 ± 6.9 cm/s and the end systolic velocity 12.7 ± 1.6 cm/s reduced significantly, while resistive index 0.74 ± 0.03 increased after 60 seconds of sustained end-range contralateral cervical rotation by 39.1%, 32.4%, and 8.8%, respectively, compared with the neutral position. There were no significant differences found between peak systolic velocity and resistive index after a stretching duration of 60 and 30 seconds. Similarly, there were no notable changes in end systolic velocity when comparing 10 seconds with 30 seconds. CONCLUSION: The static stretching exercise using sustained end-range cervical rotation for 60 seconds induced marked changes in the hemodynamics of the vertebral artery.

RESUMO

Feed additives are used frequently in variable combinations to maximize broiler productivity and consumer safety. Therefore, we evaluated the efficiency of feed additives used in four different diets: a basal diet, a probiotic (PRO-PAC®) supplement diet, an egg yolk purified immunoglobulin Y (IgY) supplemented diet, and a combination of IgY and PRO-PAC® supplement (n = 15 for each group). We assessed the improvement of behavioral and hematological parameters of Ross broilers before and after an immune stress challenge using lipopolysaccharide (LPS). Behavioral as well as physiological parameters were analyzed. The standing frequency was the highest (P < 0.05) in broilers supplemented with a combination of probiotics and IgY. Likewise, latency approach score to a novel object improved (P < 0.01) in the combination group at week-3. After intraperitoneal injection of LPS, this combination group achieved the best gait score at week-3, followed by week-5, compared to birds fed the basal diet. The heterophil/lymphocyte (H/L) ratio, heterophil differential count, and eosinophil differential count in the basal diet group that was challenged with LPS were significantly increased (P < 0.01, P < 0.001, P < 0.05, respectively) compared to the combination groups. Therefore, we concluded that the combination of IgY and probiotics can significantly improve the behavior and the underlying physiological parameters of Ross broilers. Consequently, this combination can improve the broilers' health, welfare and produce a safe meat free from harmful chemical residues.

RESUMO

BACKGROUND: Diabetic neuropathy (DN) is a common and serious complication of diabetes. DN patients are suffering from anxiety, depression, and impairment of functional capacity. Rare studies have assessed the effect of proprioceptive exercise training on anxiety, depression, and functional capacity in DN patients. AIMS: This 2-month prospective study aims to investigate the effect of proprioceptive exercise training on anxiety, depression, and functional capacity in DN patients. METHODS: Twenty-eight DN patients with a mean age of 53.2 ± 5.5 years were included in this prospective study between September and December 2019. They were randomly assigned into two groups, 14 in each group using a random number generator. The proprioceptive exercise group (PEG) received a program of proprioceptive exercise, while the control group (CG) received a conventional treatment without exercise intervention. Berg Balance Scale (BBS), Six-Minute Walk Test (6MWT), Beck Anxiety Inventory (BAI), and Hamilton Depression Rating Scale (HDRS) were investigated before and after 2 months of the study period. RESULTS: The findings showed a significant improvement of the BBS, 6MWT, BAI, and HDRS in the PEG (p = 0.003, p < 0.001, p = 0.001, and p = 0.001, respectively) while non-significant changes in the CG (p > 0.05). Comparison between the two groups showed significant differences between the two groups in the all outcome measures in favor of the PEG at the end of the 2 months (BBS, p = 0.032; 6MWT, p = 0.001; BAI, p = 0.031; and HDRS, p = 0.013). CONCLUSIONS: Two months of proprioceptive exercise may improve functional capacity, anxiety, and depression in DN patients. Serious recommendations should be devoted to encouraging the proprioceptive exercise training among different population, especially DN patients. Key Points • Proprioceptive exercise may improve postural stability in patients with diabetic neuropathy. • Proprioceptive exercise may improve psychological status and functional capacity in patients with diabetic neuropathy. • Serious recommendations should be devoted to encouraging the proprioceptive exercise training among diabetic patients.

RESUMO

AIM: This study aimed to describe the inhibitory activity of cell-free supernatants (CFS) of lactobacilli against extended-spectrum ß-lactamase (ESBL)-producing Klebsiella pneumoniae (K pneumoniae) and Pseudomonas aeruginosa (P aeruginosa). MATERIAL AND METHODS: Pathogenic clinical strains of K pneumoniae and P aeruginosa were isolated from urine samples and selected for investigation. Anti-bacterial activities of the CFS of lactobacilli were assessed by agar well diffusion, MTT assay, as well as time-kill tests. In addition, the antibiofilm characteristics were analyzed by the microplate method against fresh and 24 h-old biofilms. The ability of CFS to interfere with bacterial invasion was analyzed by flow cytometry. RESULTS: Although all tested strains were ESBL producers and showed a multidrug-resistant phenotype, the CFS displayed a high anti-ESBL activity with inhibition zone diameters greater than 13 mm in the agar well diffusion assays against both pathogens. The growth kinetics of K pneumoniae and P aeruginosa were dramatically decreased in the presence of the CFS. The CFS not only inhibited the biofilm formation by these pathogens but also was able to remove the 24-h formed biofilms. The invasion abilities of FITC-labelled K pneumoniae decreased from 30.3%±7 to 15.4%±5 and invasion of FITC-labelled P aeruginosa was reduced from 36.9%±7 to 25.2%±5. CONCLUSION: CFS of lactobacilli exhibit anti-ESBL activities, which suggests its potential application for controlling or preventing colonization of infections caused by ESBL-producing bacteria.

RESUMO

BACKGROUND: A waste disposal crisis occurred in Lebanon leading to the accumulation of garbage in the streets of Beirut. It is not clear whether such a limited crisis of improper waste disposal will lead to more diarrhea illnesses. The purpose of this study is to compare the rates of admissions due to diarrhea and characterize the illness among adults and children before, during and after the garbage crisis. MATERIALS AND METHODS: This study is an observational retrospective in-patient chart review extending over four time intervals: pre-crisis, major crisis, minor crisis, and post-crisis periods. Hospital admissions due to diarrhea or gastroenteritis were included. Descriptive analysis of the following was done: characteristics of the present illness at the time of admission, stool and lab tests ordered and management of the diarrhea illness. RESULTS: There was an increase in admission rates due to diarrhea in the months of the crisis as compared to pre and post-crisis months. The severity of diarrheal illness and the management of admitted patients were almost the same across the four periods. Rota virus diarrheal outbreak was noted during the major crisis among children less than 2 years old, and adults above 18 years old. CONCLUSIONS: Despite an increase in the rates of admissions due to diarrhea during the garbage crisis, the severity of the diarrhea illness did not differ. This may indicate that physicians and patients were more worried and utilized more health services. However, Rota outbreaks may be more prominent with improper garbage disposal.

RESUMO

BACKGROUND: Heart failure related depression is recently increased worldwide. Heart failure (HF) disease is identified as a critical cause of increasing morbidity, hospital readmission, and mortality. The most important purpose of treatment of HF disease is to relief disease problems, improve functional performance, and achieve better quality of life. OBJECTIVES: This study was proposed to evaluate the effects of low to moderate-intensity exercise program vs moderate-intensity continuous exercise program on the level of depressive disorder in heart failure patients. STUDY DESIGN: 12-week randomized controlled trial. METHODS: Sixty nine HF patients with mild to moderate level of depression and ejection fraction <40% were examined before and after 12-week intervention. Their age was ranged from 40 to 60 years. Patients were randomly classified into 3 groups. Group I (n = 23) received low to moderate intensity exercise program (LMIEP), group II (n = 23) received moderate-intensity exercise program (MICEP), and group III (n = 23) did not receive any exercise program (Non-exercised group). All patients were instructed to conduct home-based exercise with their pharmacological therapy. The level of depression was evaluated before and after 12 weeks of the intervention program. RESULTS: The 3 study groups were associated with significant decrease of depression level (P < .05). Significant differences were exhibited between the 3 groups in favor to both exercise programs (P < .05) with non-significant differences between the 2 exercise programs (P > .05). CONCLUSIONS: Both exercise programs had positive effects in reducing the severity of depression in HF patients. Low to moderate and moderate-intensity exercise programs should be proposed for depression illness specially patients with heart failure.

RESUMO

Background: Although physical exercise is a crucial element in the management of childhood obesity, the most effective training intensity and duration remain controversial. The primary purpose of this study was to analyze the interaction effects of exercise intensity and duration on cardiovascular risk profile, maximum oxygen uptake ( VO 2 max ), and rating of perceived exertion (RPE) in obese children. Methods: Eighty obese children were allocated evenly to four groups (20 in each group): groups I and II performed 20 -minute and 40-minute constant-load treadmill training, respectively, with the intensity set at running speed, corresponding to 100% of first ventilatory threshold (VT1), and groups III and IV performed 20 -minute and 40-minute training, respectively, with the intensity set at running speed, corresponding to 80% of VT1. Training was conducted every other day for eight consecutive weeks. Blood lipids, VO 2 max , and RPE were assessed pre- and postintervention. Results: Postintervention, significant between-group differences regarding all outcome measures (P<0.05) were indicated. Total cholesterol level had dropped significantly in group II compared to the other groups (adjusted P<0.05), and low-density lipoprotein and triglycerides had decreased significantly in group II compared to group III (adjusted P=0.003 and 0.007, respectively). VO 2 max had increased significantly in group II compared to group I (adjusted P=0.008). RPE had decreased significantly in group II in comparison to other groups (adjusted P<0.05). Conclusion: Intensity and duration are essential factors in aerobic-exercise prescription to reduce cardiovascular risk factors, increase oxygen uptake, and improve perceived exertion in obese children.

RESUMO

A 54-year-old woman presents with a long history exertional chest pain and was found to have left ventricular systolic dysfunction on trans-thoracic echocardiogram. Coronary angiography revealed no evidence of atherosclerotic coronary artery disease and showed multiple micro-fistulae draining from all three major coronary arteries to the left ventricle. This rare abnormality is the result of failure of obliteration of intra-trabecular embryonic sinusoids and may cause myocardial ischemia through the coronary steal mechanism.

RESUMO

Acute myocardial infarction (MI) is commonly a result of coronary atherosclerotic plaque rupture and superimposed thrombus formation. Nevertheless, uncommon causes of MI including embolism from aortic root and ascending aorta mural thrombi must be considered when coronary atherosclerotic disease is not evident. We report a case of a 84-year-old woman who presented with an inferior ST-segment elevation MI. Initial attempts to engage the right coronary artery (RCA) were unsuccessful. Aortic angiography revealed evidence of the left coronary artery ostium with absence of the right coronary ostium or RCA. Probing with a coronary wire where the RCA ostium was presumed to be located yielded resolution of the ST-segment elevation. The RCA was then easily engaged using a guide catheter, and angiographic evaluation showed a smooth vessel with no evidence of coronary artery disease except for abrupt termination of the distal PL2 branch. Contrast-enhanced computed tomography revealed an aortic root thrombus extending into the right coronary sinus of Valsalva and a thrombus in the left atrial appendage. The case reveals RCA embolism from an aortic root thrombus likely originating from the left trial appendage. A conservative approach to treatment with anticoagulation was pursued that resulted in full recovery. A review of the literature revealed that the etiology of aortic root thrombi is proposed to be multifactorial. Prospective randomized studies are needed to demonstrate the best treatment approach, although this appears to be impracticable given the rarity of the disease.
