ABSTRACT

OBJECTIVE: To examine the impact of telerehabilitation training on exercise capacity, lung function, and health-related quality of life (HRQOL) in comparison to no rehabilitation for post-COVID-19 symptoms in adult females. METHODS: A randomized controlled trial of 48 females after mild to moderate COVID-19 survival were equally and randomly assigned to one of two groups: intervention group or control group. Three sessions per week for 6 weeks of a telerehabilitation program provided via a smartphone to the intervention group. Spirometry was used to quantify lung function, a 6-minute walk test (6MWT) measured in meters to measure exercise capacity, and the Short Form Health Survey-36 was used to assess HRQOL. RESULTS: After treatment, there was no statistically significant difference in forced vital capacity (FVC) or forced expiratory volume in 1 second (FEV1) between groups (p>0.05), but the 6MWT of the intervention group increased significantly more than that of the control group (p=0.001). The percent of change in 6MWT for the intervention group and control group was 14.22% and 4.21%, respectively. After therapy, the intervention group's HRQOL significantly improved when compared to the control group's (p=0.001). CONCLUSION: This study showed that a telerehabilitation programs improved exercise capacity and HRQOL in young females post-COVID-19 compared to no rehabilitation.

ABSTRACT

Vascular complications lead to morbidity and mortality in patients with diabetes. Diabetic nephropathy (DN) is one of the main life-threatening problems for these patients, as it is the main cause of end-stage renal disease. This study aimed to measure the clinical effects of diabetes in patients with diabetes and in patients with diabetic nephropathy. Improved hypoglycemic control in patients with diabetes could impressively reduce platelet hyperreactivity, and oxidative stress alters the levels of many coagulation and thrombosis factors, resulting in an abnormal hemostasis and impaired levels of numerous serum markers. Most studies have revealed that coagulation factor levels are high in patients with diabetes and nephrodiabetes. Serum inflammatory factors, and coagulation and endothelial functions are good predictors of diabetic nephropathy. This literature review was conducted with access to scholarly databases and Google Scholar through Qassim University, and it analyzes studies from early 2010 until November 2020. Many studies have inferred that diabetes severely affects hemostasis and increases the risk of cardiovascular disease.

ABSTRACT

PURPOSE: This study aimed to compare the effects of virtual reality (VR) training and resistance exercises training on lymphedema symptom severity as well as physical functioning and QoL in women with breast cancer-related lymphedema (BCRL). METHODS: In a single blinded randomized trial, women diagnosed with unilateral BCRL were randomly divided into two groups: the Xbox Kinect group received VR Kinect-based games (n = 30) and resistance exercise group received resistance training (n = 30). In addition, both groups received complex decongestive physiotherapy (manual lymphatic drainage, compression bandages, skin care, and exercises). The intervention was conducted five sessions per week for 8 weeks. The outcome measures included excessive limb volume, visual analogue scale (VAS), the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire, shoulder range of motion (ROM), shoulder muscles strength, hand grip strength, and Study Short-Form (SF-36). The outcomes were evaluated pre and post intervention (week 8). RESULTS: Statistical significant differences were recorded in VAS (pain intensity), DASH, shoulder ROM (p < 0.001), bodily pain (p = 0.002), general health (p < 0.001), and vitality (p = 0.006) in favor of the Xbox Kinect group. However, there were statistically significant differences in shoulder flexion strength (p = 0.002), external rotation strength (p = 0.004), and abduction strength and handgrip strength (p < 0.001) in favor of the resistance exercise group. CONCLUSIONS: The VR training was superior to resistance exercises training in BCRL management. The empirical findings support the VR as a new effective and encouraging intervention modality which can assist in improving physical functioning and quality of life in women with BCRL. TRIAL REGISTRATION: This study is retrospectively registered at ClinicalTrials.gov (ID: NCT04724356).

ABSTRACT

The reduction in estrogen levels results in a decrease in bone density at menopause. Irisin is a myokine that modulates the benefits of exercise, which may include bone health. This study was planned to examine irisin's impact in preventing osteoporosis after ovariectomy. 4 groups of female albino rats (10 rats/group): control, sham-operated, ovariectomized (OVX-control), and OVX-irisin-treated. Serum levels of bone markers [osteocalcin (OC), bone alkaline phosphatase (BALP), tartrate-resistant acid phosphatase (TRAP), calcium (Ca++), phosphorus (P)], glucose, and insulin were being measured. Body mass index, Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), dry and ash femur weight, and bone contents of Ca++ and P were investigated. The femur was examined histopathologically. The OVX-control group showed an increase in serum levels of OC, BALP, TRAP, calcium, phosphorus, BMI, glucose, insulin, and HOMA-IR (P < 0.05) and a reduction in dry and ash weight of the femur, the concentration of calcium and phosphorus content in bone ash (P < 0.05). The OVX-irisin-treated group exhibited a decrease in serum levels of OC, BALP and TRAP, calcium, phosphorus, BMI, glucose, insulin, HOMA-IR (P < 0.05), and a rise in dry and ash weight of the femur, the concentration of calcium and phosphorus in bone ash (P < 0.05). Histological examination of the distal femur diaphysis of the OVX-irisin-treated group exhibited proper bone architecture and density compared with that of the OVX-control group. It is concluded that irisin treatment in the OVX rats safeguarded the regular bone architecture and normal levels of serum bone biomarkers. Irisin may be a possible novel target in the prohibition of postmenopausal osteoporosis.

ABSTRACT

The aim of the present study was to assess the short-term effects of Thymoquinone (TQ) on oxidative stress, glycaemic control, and renal functions in diabetic rats. DM was induced in groups II and III with a single dose of streptozotocin (STZ), while group I received no medication (control). The rats in groups I and II were then given distilled water, while the rats in group III were given TQ at a dose of 50 mg/kg body weight/day for 4 weeks. Lipid peroxidase, nitric oxide (NO), total antioxidant capacity (TAC), glycated haemoglobin (HbA1c), lipid profiles, and renal function were assessed. Moreover, the renal tissues were used for histopathological examination. STZ increased the levels of HbA1c, lipid peroxidase, NO, and creatinine in STZ-induced diabetic rats in comparison to control rats. TAC was lower in STZ-induced diabetic rats than in the control group. Furthermore, rats treated with TQ exhibited significantly lower levels of HbA1c, lipid peroxidase, and NO than did untreated diabetic rats. TAC was higher in diabetic rats treated with TQ than in untreated diabetic rats. The histopathological results showed that treatment with TQ greatly attenuated the effect of STZ-induced diabetic nephropathy. TQ effectively adjusts glycaemic control and reduces oxidative stress in STZ-induced diabetic rats without significant damaging effects on the renal function.

ABSTRACT

PURPOSE: Blood transfusion is a conventional therapeutic procedure; however, the perceptions of general public and healthcare professionals (HCPs), especially physicians and nurses, remain unclear, although the insights of HSPs may affect the treatment decision. This study aimed to assess the awareness of HCPs and the public about blood transfusion risks and consent in Qassim region of Saudi Arabia, to uncover the factors that may influence such perceptions. PATIENTS AND METHODS: This study used two different closed questionnaires that were distributed electronically between February and March 2018 among the population and HCPs in Qassim region. RESULTS: A total of 400 general public participants and 135 HCPs completed the survey. Among the surveyed participants, 70% believed that blood transfusion therapy was safe. The perceived risk of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) was the highest among all complications (74%). Furthermore, 88.2% of respondents were willing to accept a blood transfusion as a therapeutic measure, primarily from a first-degree relative, although the remaining 11.8% rejected the idea of a transfusion due to fear of medical error. From the HCP survey, 80% were previously involved in a blood transfusion therapy consent process. HCPs typically reported explaining the benefits, risks, and alternatives described in the consent form (74.1%, 67.4%, and 53.3%, respectively). CONCLUSION: Our results indicated that despite the current high level of acceptance and knowledge regarding blood transfusions, additional educational efforts remain necessary to increase public awareness of blood transfusion therapy.

ABSTRACT

Despite the extensive use of cisplatin (CP) as a chemotherapeutic agent, its clinical use is often restricted by undesirable side effects, such as toxicity to normal tissues. The aim of this study was to probe the effect of a combinatorial treatment of low multiple doses of antioxidants on CP-induced toxicity and the mitochondrial apoptotic pathway in hepatocytes. Animals received a single toxic dose of CP (7.5 mg/kg body weight) with or without combined multiple doses of epigallocatechin gallate (EGCG) and coenzyme Q10 (CoQ10) (15 and 5 mg/kg body weight, respectively). CP-treated animals showed altered biochemical parameters, denoting hepatotoxicity, which was markedly improved by the multidose treatment with EGCG + CoQ10. The increased levels of oxidants found in the cytosolic and mitochondrial fractions isolated from the liver of CP-administered rats were significantly attenuated by the combinatorial doses of antioxidants. EGCG + CoQ10 ameliorated the CP-induced compromised antioxidant defenses, oxidative modification of macromolecules, decreased activities of respiratory chain enzymes, altered membrane depolarization, and swelling of liver mitochondria. Furthermore, EGCG + CoQ10 treatment inhibited CP-induced apoptosis by suppressing the activation and mitochondrial accumulation of proapoptotic proteins and preventing the inhibition of antiapoptotic protein expression, cytochrome c efflux, caspase-3 activation, and DNA fragmentation. Histological findings further confirmed the protective effects of EGCG + CoQ10 against CP-induced cellular injury. Our findings revealed that the combination of EGCG and CoQ10, owing to their individual antioxidant properties, can be an effective remedy, which by maintaining redox hemostasis attenuate the mitochondrial stress-mediated molecular and cellular processes involved in CP-induced liver toxicity and cell death.

ABSTRACT

SARS-CoV-2, an epidemic, causes severe stress in both human and animals and may induce oxidative stress (OS) and increases susceptibility to infection. Domestic animals are found infected by their COVID-2 suffering owners. Chronic immobilization stress (CIS), a model of psychological and physical stress of confinement, can trigger depression and anxiety in animals. We evaluated the ameliorative effect of the proposed SARS-CoV-2 prophylactic drugs melatonin, vitamin C, and zinc on CIS-induced OS, inflammation, and DNA damage in rats. Forty male Swiss albino rats (200-250 g, 7-9 weeks old) were divided into five groups as controls, CIS, treated with melatonin (20 mg/kg), and vitamin C plus zinc [VitC+Zn (250 + 2.5 mg/kg)] alone or in combination (melatonin+VitC+zinc) subjected to CIS for 3 weeks. CIS was induced by immobilizing the whole body of the rats in wire mesh cages of their size with free movement of head. Exposure to CIS significantly compromised the circulatory activities of superoxide dismutase, catalase, and glutathione with enhanced malondialdehyde, inflammatory markers (IL-6, IL10, and TNFα), and lymphocyte DNA damage in comparison to controls. Treatment with melatonin and VitC+Zn alone or in combination significantly restored the altered biochemical parameters and DNA damage of stressed rats to their respective control values. However, the cumulative action of melatonin with VitC+Zn was more effective in alleviating the CIS-induced OS, inflammation, and DNA damage. The present study indicates that the antioxidant combination can be an effective preventive measure to combat severe psychological and confinement stress-induced biochemical changes in animals due to abnormal conditions such as SARS-CoV-2.

ABSTRACT

Free radical involvement in initiation, promotion and progression of carcinogenesis, implicates that scavengers of free radicals may act as inhibitors in the carcinogenic process. Melatonin, an antioxidant was used in the present study to evaluate its effectiveness on skin carcinogenesis induced by DMBA both with and without chronic restraint stress (CRS). Fifty Swiss albino young male rats were divided into five groups of 10 rats each as controls, topical DMB alone, Pre CRS-DMBA, melatonin DMBA and Pre-CRS-DMBA-melatonin treated groups. After 18 weeks blood was collected along with liver and skin samples. These were used for antioxidant enzyme assay, DNA damage and fluorescent spectra analysis. Melatonin showed antioxidant potential in combatting DMBA induced skin carcinogenesis measured by free radical scavenging enzymes and in vivo antioxidant status, DNA damage. Sensitive detection of the DMBA induced micro biochemical changes was possible by fluorescent spectroscopy from the transformed ratio of fluorescent intensity (F1 530 nm/630 nm) otherwise found constant for normal tissues. By melatonin treatment this ratio was similar to control values. The decreased antioxidant biochemical parameters depicting oxidative stress were comparable to comet assay and fluorescent studies, endorsing the chemo-preventive efficacy of melatonin against skin carcinogenesis caused by DMBA. CRS pre-exposure diminished the chemo-preventive/antioxidant ability of melatonin and the results were same as DMBA alone treatment, showing stress affected both cancer development and chemoprevention. CRS decreased the antioxidant potential of melatonin. Hence, managing stress could be perceived in cancer chemoprevention. Further studies focusing on stress reduction are needed.

ABSTRACT

OBJECTIVE: To investigate the efficacy of extracorporeal shockwave therapy (ESWT) on cervical myofascial pain following neck dissection in reducing pain and improving cervical range of motion (ROM). METHODS: Forty-six patients with cervical myofascial pain following neck dissection surgery were recruited and subdivided at random into two equal groups. The ESWT group received ESWT once a week for 4 weeks (0.25 mL/mm2, 1,000 shocks) and a topical non-steroidal anti-inflammatory drug (3 times/day for 4 weeks). The control group received only topical NSAID. The pain assessment was done by using the visual analog scale (VAS) and pressure algometry. A cervical ROM device was used for the assessment of the lateral flexion and rotation of the neck ROM on both sides. All measurements were collected at baseline, 2 weeks, and 4 weeks. RESULTS: The ESWT group revealed a significant improvement in all parameters at post I and post II than did the control group (p>0.001), that revealed a statistical decrease only in the VAS score at post I without any statistical difference in the pain threshold and neck ROM. However, there were statistical differences in all parameters at post II compared to those at pre-treatment and post I (p<0.001). CONCLUSION: As a confirmation of the efficacy of ESWT in cervical myofascial pain control following neck dissection, we observed better results with no side effects in the ESWT group (Clinical Trial Registry No. PACTR202002648274347).

ABSTRACT

OBJECTIVE: To determine the efficacy of a three-month resistance training programme on the mobility, muscle strength and lean body mass of patients with pancreatic cancer-induced cachexia. DESIGN: Randomized controlled trial. SETTING: Elsahel Teaching Hospital, outpatient clinic of the Faculty of Physical Therapy, Cairo, Egypt. PARTICIPANTS: Patients with pancreatic cancer-induced cachexia. INTERVENTIONS: Participants were randomized to the resistance training group (n = 20) and control group (n = 20). MAIN MEASURES: Outcomes including mobility, muscle strength and lean body mass were measured at baseline, three months after surgical resection and 12 weeks after intervention. RESULTS: The mean (SD) age was 51.9 (5.03) years and body mass index was 21.1 (1.13) kg/m²; 65% of patients were male. Compared to the control group, the resistance training group showed significant improvement in mobility: 400-m walk performance (270.3-256.9 seconds vs 266.4-264.2 seconds, respectively) and chair rise (13.82-12.53 seconds vs 13.77-13.46 seconds, respectively). Similarly, muscle strength was also significantly improved in the resistance training group than in the control group; we observed increase in peak torque of knee extensors (P = 0.004), elbow flexors (P = 0.001) and elbow extensors, improvement in lean mass of the upper limb (6.28-6.46 kg vs 6.31-6.23 kg, respectively) and lower limb (16.31-16.58 kg vs 16.4-16.31 kg, respectively). CONCLUSION: A three-month resistance training improved the mobility of patients with pancreatic cancer-induced cachexia. Muscle strength and lean body mass also improved.

ABSTRACT

Nephrotic syndrome (NS) is a disease of glomerular filtration barrier failure presenting with variable degrees of proteinuria, hypoalbuminemia, hyperlipidemia, and edema. Inflammation may contribute to the pathogenesis of NS. The aim of this study was to monitor the serum levels of three cytokines [i.e., granulocyte chemotactic protein-2 (GCP-2), growth-related oncogene-α (GRO-α), and interleukin-8 (IL-8)] in different stages of NS and to find out whether changes in the levels of these cytokines could be related to the severity of NS. This study included 125 patients who were divided into 40 patients with nephrotic range proteinuria (NRP), 45 patients with NS, and 40 patients who were in remission. This study also included 80 healthy participants as a control group. Enzyme-linked immunosorbent assay was used for the determination of the plasma levels of GRO-α, GCP-2, and IL-8. GCP-2 plasma levels were significantly higher in the NS and NRP groups when compared to the control group, whereas the GRO-α and IL-8 levels were significantly higher in all patient groups in comparison with the control group. All these chemokine levels were significantly decreased in remission as compared with the participants in the NS group (P <0.0001). There was a significant correlation between the cytokine levels and proteinuria and serum albumin in the NS group (P <0.0001). However, in the follow-up group, GCP-2 levels were significantly lower during remission as compared to those with active NS (P <0.0001). Our findings suggest that the pro-inflammatory cytokines GCP-2, GRO-α, and IL-8 could play a role in the pathogenesis of NS, particularly glomerular permeability.
