Background. To the best of our knowledge, no studies have evaluated the effects of inspiratory muscle training (IMT) on recovered COVID-19 patients after weaning from mechanical ventilation. Therefore, this study assessed the efficacy of IMT on recovered COVID-19 patients following mechanical ventilation. Methods. Forty-two recovered COVID-19 patients (33 men and 9 women) weaned from mechanical ventilation with a mean age of 48.05 ± 8.85 years were enrolled in this pilot control clinical study. Twenty-one patients were equipped to 2-week IMT (IMT group) and 21 matched peers were recruited as a control (control group). Forced vital capacity (FVC%), forced expiratory volume in 1 second (FEV1%), dyspnea severity index (DSI), quality of life (QOL), and six-minute walk test (6-MWT) were assessed initially before starting the study intervention and immediately after intervention. Results. Significant interaction effects were observed in the IMT when compared to control group, FVC% ( F = 5.31, P = .041, η P 2 = 0.13), FEV1% ( F = 4.91, P = .043, η P 2 = 0.12), DSI ( F = 4.56, P = .032, η P 2 = 0.15), QOL ( F = 6.14, P = .021, η P 2 = 0.17), and 6-MWT ( F = 9.34, P = .028, η P 2 = 0.16). Within-group analysis showed a significant improvement in the IMT group (FVC%, P = .047, FEV1%, P = .039, DSI, P = .001, QOL, P < .001, and 6-MWT, P < .001), whereas the control group displayed nonsignificant changes ( P > .05). Conclusions. A 2-week IMT improves pulmonary functions, dyspnea, functional performance, and QOL in recovered intensive care unit (ICU) COVID-19 patients after consecutive weaning from mechanical ventilation. IMT program should be encouraged in the COVID-19 management protocol, specifically with ICU patients.
Objective: To find and compare the clinical and psychological effects of low and high-intensity aerobic training combined with resistance training in community-dwelling older men with post-COVID-19 sarcopenia symptoms. Design: Randomized control trial. Setting: University physiotherapy clinic. Participants: Men in the age range of 60–80 years with post-COVID-19 Sarcopenia. Intervention: All participants received resistance training for whatever time of the day that they received it, and that in addition they were randomized into two groups like low-intensity aerobic training group ( n = 38) and high-intensity aerobic training group ( n = 38) for 30 minutes/session, 1 session/day, 4 days/week for 8 weeks. Outcomes: Clinical (muscle strength and muscle mass) and psychological (kinesiophobia and quality of life scales) measures were measured at the baseline, fourth week, the eighth week, and at six months follow-up. Results: The 2 × 4 group by time repeated measures MANOVA with corrected post-hoc tests for six dependent variables shows a significant difference between the groups ( P < 0.001). At the end of six months follow up, the handgrip strength, −3.9 (95% CI −4.26 to −3.53), kinesiophobia level 4.7 (95% CI 4.24 to 5.15), and quality of life −10.4 (95% CI −10.81 to −9.9) shows more improvement ( P < 0.001) in low-intensity aerobic training group than high-intensity aerobic training group, but in muscle mass both groups did not show any significant difference ( P > 0.05). Conclusion: Low-intensity aerobic training exercises are more effective in improving the clinical (muscle strength) and psychological (kinesiophobia and quality of life) measures than high-intensity aerobic training in post-COVID 19 Sarcopenia.
High costs of conventional protein feed sources including soybean meal (SBM) generated the need for finding other alternatives. Thus, the present study was designed to evaluate the impact of graded replacements of SBM by sunflower seed meal (SFM) with or without enzyme supplementation on growth performance, digestive enzymes, carcass traits, and blood profile of broiler chickens. A total of 240 unsexed 1-week-old broiler chicks (Hubbard) were randomly divided into eight treatment groups of 30 chicks each in five replicates each of six chicks in a factorial design (4 × 2) arrangement, including four levels of SFM (0, 25, 50, and 75% replacing SBM) and two levels of enzyme (0- or 0.1-g/kg diet) supplementation. Performance traits including feed conversion ratio, body weight, and weight gain were significantly (P < 0.01) improved with increasing SFM up to 50% substitution for SBM or with enzyme supplementation in broiler diet during the experiment. However, feed intake of broiler chicks was decreased with enzyme supplementation (P < 0.05). The activities of digestive enzymes (protease and amylase) were significantly (P < 0.05) influenced and enhanced by SFM and enzyme inclusion in diets, respectively. The activities of protease and amylase were improved with SFM diet supplemented with 0.1 g/kg enzyme in comparison with those with the un-supplemented diet. The evaluated carcass traits were not statistically (P > 0.05) influenced by feeding SFM meal or enzyme addition. Biochemical blood parameters were significantly (P < 0.01) affected by SFM, enzyme, or their interaction in broiler diets, except for globulin that was not affected by dietary enzyme. It is concluded that increasing SFM level in the diet up to 50% replacing SBM with the supplementation of enzyme improved the growth performance and enhanced positively carcass traits as well as the activity of digestive enzymes in broiler chickens.
A total of 200 1-week-old Japanese quails were randomly allocated into five treatment groups, each consisting of 40 unsexed birds (five replicates, eight birds each). Quails were reared in traditional cages (90 Â 40 Â 40 cm), and feed and water were made available throughout the 5-week trial. The treatment groups were as follows: the 1st was fed basal diet, whereas the 2nd, 3rd, 4th, and 5th groups were fed with ration supplemented with nano zinc (Zn-NPs) at doses of 0.1, 0.2, 0.3, and 0.4 g/kg diet, respectively. Results showed that, a significant (p .0001) improvement in body weight, weight gain, feed intake, and feed conversion ratio was observed in birds fed diets supplemented with 0.2 g/kg of Zn-NPs. Supplementation of Zn-NPs at doses of 0.1-0.3 g/kg diet demonstrated a positive impact on the activity of ALT, AST, and LDH. The liver profile parameters were not statistically influenced (p > .05) by dietary biological nano zinc, with the exception of total cholesterol (TC), high density lipoprotein (HDL), and low density lipoprotein (LDL). Also, dietary supplementation of biological Zn-NPs at concentrations of 0.1-0.3 g/kg diet demonstrated a positive impact on superoxide dismutase (SOD), glutathione peroxidase (GPX), malondialdehyde (MDA), immunoglobulin G (IgG), and immunoglobulin M (IgM). Dietary supplementation of Zn-NPs led to an increase in beneficial microbial populations. From the obtained results, Zn-NPs supplementation at 0.2 g/kg diet had a positive effect on the performance and physiological status of growing Japanese quails. HIGHLIGHTSZinc (Zn) is an important trace element for the general functioning of the animal body. A significant improvement in growth performance was observed in birds fed diet enriched with 0.2 g/kg of Zn-NPs. Supplementation of Zn-NPs (0.1-0.3 g/kg diet) demonstrated a positive impact on immunity and antioxidant indices ARTICLE HISTORY
This study was to investigate the effect of dietary protein levels and supplementation with two cold‐pressed oils on the performance, immunity and antioxidant indices of growing Japanese quails. A 3 × 4 factorial experiment, using 3 dietary crude protein (CP) levels (22%, 24% and 26%) and 4 supplemental herbal oils levels: control without additives, 250 mg marjoram (Mar), 250 mg thyme (Thy) and 125 mg Mar + 125 mg Thy per kg diet. A total of 720 unsexed, 7‐day‐old quail chicks were randomly distributed into twelve treatment groups (4 replicates per group of 15 chicks in each). The live body weight (LBW) on 42 days and body weight gain (BWG) from 7 to 42 days were significantly improved (p < 0.01 and 0.05) in chicks fed 24% or 26% CP compared with those of the 22% CP group. The groups fed diets supplemented with Mar or in combination with Thy oil exhibited significantly better LBW, BWG and feed conversion ratio (FCR) than the control at all periods except BWG from 21 to 42 days and FCR from 7 to 21 days were not significant. Feed intake was gradually decreased with increasing dietary CP level or adding herbal oils during the periods 21–42 and 7–42 days of age. Plasma triglycerides, cholesterol, total lipids and malondialdehyde were decreased by cold‐pressed oils supplementation, but the activity of reduced glutathione and superoxide dismutase was increased (p < 0.01) compared with the control. In conclusion, quails fed a diet containing 24% or 26% CP or diets supplemented with Mar or Thy oils or both exhibited improvement in the performance, lipid profile, immunity and antioxidant capacity without any detrimental impacts on the other studied parameters.
Background: Chronic non-specific low back pain (LBP) is gradually increasing among populations worldwide and affects their activities. Recently, the Nd:YAG laser has been presented in the rehabilitation field. Objectives: This study aims to explore the short-term effects of the Nd:YAG laser on chronic non-specific LBP individuals. Methods: Thirty-five individuals with chronic nonspecific LBP were included in the study from December 2019 to March 2020. Randomly, they were categorized to Nd:YAG group (n = 18) and sham laser as a control (n = 17) thrice weekly for a 6-week intervention. Modified Oswestry disability index (MODI), pain disability index (PDI), visual analogue scale (VAS), and lumbar flexion range of motion (ROM) have been assessed pre and post-6 weeks of the intervention. Results: Significant improvements were observed in the Nd:YAG group (MODI, P < .001; PDI, P = .007; VAS, P < .001; lumbar ROM, P = .002), whereas the sham group showed no significant changes (MODI, P = .451; PDI, P = .339; VAS, P = .107; lumbar ROM, P = .296) after 6-week intervention. Between-group comparisons showed significant differences in tending toward the Nd:YAG group (MODI, P < .001; PDI, P = .046; VAS, P < .001; lumbar ROM, P = .003). Conclusions: Regarding the present study outcomes, short-term pulsed Nd:YAG laser (6 weeks) may reduce functional disabilities and pain intensity, and improve the lumbar flexion ROM in patients with chronic nonspecific LBP. Further well-designed randomized controlled studies with large sample sizes should be conducted regarding laser treatment.
Objective. Limited studies have assessed the effect of moderate-intensity continuous aerobic exercise on hepatic fat content and visceral lipids in hepatic patients with diabesity. is study was designed to evaluate hepatic fat content and visceral lipids following moderate-intensity continuous aerobic exercise in hepatic patients with diabesity. Design. A single-blinded randomised controlled trial. Methods. irty-one diabetic obese patients with nonalcoholic fatty liver disease were recruited into this study. e patients were randomly classified into exercise and control groups, fifteen patients in the exercise group and sixteen patients in the control group. e exercise group received an 8-week moderate-intensity continuous aerobic exercise program with standard medical treatment, while the control group received standard medical treatment without any exercise program. Hepatic fat content and visceral lipids were assessed before and after intervention at the end of the study. Results. Baseline and clinical characteristics showed a nonsignificant difference between the two groups (p > 0.05). At the end of the intervention, the aerobic exercise showed significant improvements (serum triglycerides and low-density lipoproteins (LDLs), p ≤ 0.002, total cholesterol, p � 0.004, visceral fats, p � 0.016, glycated hemoglobin (HbA1C), p � 0.022, high-density lipoproteins (HDLs), p � 0.038, alanine transaminases (AL), p � 0.044, intrahepatic triglyceride and HOMA-IR, p � 0.046, and body mass index (BMI), p � 0.047), while the control group showed a nonsignificant difference (p > 0.05). e postintervention analysis showed significant differences in favor of the aerobic exercise group (p < 0.05). Conclusions. Moderate-intensity continuous aerobic exercise reduces the hepatic fat content and visceral lipids in hepatic patients with diabesity. Recommendations should be prescribed for encouraging moderate-intensity aerobic exercise training, particularly hepatic patients with diabesity.
The main objective of this work was to investigate the impact of dietary chromium supplementation on growth indices, carcass yield, and some hematological and biochemical blood parameters of growing Japanese quails subjected to heat stress. A total of 360 unsexed 2-week-old Japanese quail chicks were used in a 2 × 3 factorial arrangement that had two ambient temperatures (23 ± 2 and 33 ± 2 °C) and three dietary chromium (0.00, 500, and 1000 μg Cr/kg diet as chromium picolinate). For induction of heat stress, the room temperature was set at 33 ± 2 °C from 2 to 6 weeks of age. Results showed that body weight, body weight gain, and feed intake were decreased for birds subjected to heat stress condition during 2 to 4 and 2 to 6 weeks of age. Feed conversion was not significantly (P> 0.05) affected by high ambient temperature throughout the experiment. Carcass, dressing, liver, and heart percentages were not influenced by the ambient temperature or dietary chromium or their combinations. Significant temperature × chromium combinations were observed for hemoglobin value (P = 0.025) and packed cell volume (P = 0.001). Cholesterol and glucose in plasma were increased (P = 0.004 or 0.022) in quails subjected to heat stress condition. Plasma measurements of total proteins, albumin, globulin, lipids, glucose, and A/G ratio of quail chicks were not influenced (P > 0.05) by chromium, while cholesterol was increased with increasing chromium level (P = 0.033). High ambient temperature or dietary chromium levels or their interactions did not (P > 0.05) affect plasma levels of aspartate transaminase (AST), alanine transaminase (ALT), triiodothyronine (T3), thyroxin (T4), or T3/T4 ratio of growing quails. From these observations, it can be concluded that dietary chromium supplementation of growing Japanese quail subjected to heat stress condition could beneficially affect growth performance and carcasses, as well as modulate the hematological and biochemical blood parameters, probably through modulating stress status.
