There are about 1296 clinical studies being (or have been) conducted in Saudi Arabia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Background: Children often suffer from disorders that alter their walking functions, such as cerebral palsy. Task-oriented training is one of the recent interventions to improve gait in children with cerebral palsy (CP). Some studies have shown the effectiveness of Partial Body Weight Support Treadmill Training (PBWSTT) for children with cerebral palsy. Another study supports the effectiveness of Loaded Treadmill Training (LTT) by placing additional weight on the lower extremity. There is still inconsistency in the results of studies advising which weight support or weight addition is more appropriate to use in improving walking in children with cerebral palsy. Objectives: This study aims to investigate the effectiveness of PBWSTT in the treatment of children with CP. Furthermore, to compare the effectiveness of LTT with PBWSTT. Methods: Two groups of twenty-two children with spastic cerebral palsy will be involved. Ages 4 to 10 and Gross Motor Functional Classification System (GMFCS) I -III. PBWSTT includes a 45- minute treadmill training session with 30% weight support for group one and LTT by adding 60% weight to lower limb while treadmill training for the second group. Spatiotemporal parameters will be measure additional to balance and endurance functions. Statistical analysis: Independent t test will be used to detect between group differences and paired t test to detect before and after trial differences. Significance level less than 0.05 and confidence interval 95%. Study design: Randomized Clinical Trial (Parallel Arm Design).
Background: Vibratory stimulation is one of several non-pharmacological techniques used to reduce pain. Local vibration therapy generates vibrations that can penetrate up to 6 centimeters into the tissue and is utilized to manage muscle tone, alleviate localized pain, and induce an increase in blood and lymphatic circulation. This therapy is most commonly used to treat chronic pathologies of the muscles, tendons, and joints. A few studies investigating the effects of local vibration therapy on skeletal muscles and joints have found it to be beneficial in improving joint mobility and decreasing pain. Previous reports have indicated that whole-body vibration can suppress chronic low back pain, knee osteoarthritis, and peripheral neuropathy. The aim of this study is to evaluate the effects of the application of vibration stimulation on upper extremity injection-induced pain and satisfaction. Objectives: The purpose of this study is to assess the effect of vibration stimulation application on upper extremity injection pain and satisfaction. Methods: An electrical massage kit that induces vibration will be used on adult patients who are scheduled to receive local anesthesia or corticosteroid injections in their upper extremities. Two validated scales will be used to first assess the pain after the injection and the patient's satisfaction following the use of the vibration device.
Gingival diseases occur commonly in the global population and herbal products for its intervention have limited body of research evidence. This study to evaluate the clinical efficacy of 5% thymoquinone (TQ) gel as an adjunct to scaling and root planing (SRP) in patients diagnosed with gingivitis. OBJECTIVE: To evaluate the efficacy of 5% TQ gel using a novel liposome drug delivery as a topical application following SRP in gingivitis patients. DESIGN: Double-blinded, parallel, randomized controlled clinical trial. SETTING: Faculty of Dentistry, King Abdulaziz University, and Qassim University, Saudi Arabia
Background: Chronic neck pain (CNP) is a major health problem affecting individuals with high prevalence and subsequent complications which interfere with the physical, personnel, and psychological status. The capacitive and resistive radiofrequency therapy (CRRT) is a relatively new treatment modality used in rehabilitation with no evidence on its efficacy on chronic neck pain. Objective: The aim of the present study is to investigate the effect of the CRRT alone or with manual therapy in the treatment of patients with patients with non-specific CNP. Hypotheses Is the application of the CRRT when applied alone or with combination with manual therapy and exercises effective in decreasing pain and improving the function and strength in patients with non-specific chronic neck pain?? Methods: 60 patients will participle in the study. They will be recruited from the hospital in mecca, Saudi Arabia. They will be randomized into three groups. Group I will be treated with stretching exercises (EX) and manual therapy (Manual + EX group). Group II will be treated with CRRT plus exercises (CRRT+ EX group). Group III will be treated by EX plus manual therapy applied during CRRT for groups (Manual + CRRT+ EX group). For groups II and III, capacitive electrodes will be applied for five minutes. Then the resistive electrodes will be applied for 10 minutes and finally the capacitive will be applied again for another five minutes. Assessment of the neck pain, function, CROM, trigger points, neck muscle strength as well as neck angles will be performed. Measurement will be performed before, after 6 weeks, and 6 months of treatment as follow up measurements. Multivariate analysis of variance was used to compare between and within groups. The level of statistical significance is set as P<0.05.
Different modalities ranging from patient controlled analgesia (PCA) to different regional blocks have been used to control postoperative pain after thoracic surgeries. Thoracic epidural analgesia and paravertebral blocks are effective modes of pain relief but have the risks of severe complications and side effects which include severe hypotension, nerve injury or spinal cord injury, vascular injury and pleural injury etc. Erector spinae plane block (ESPB) is relatively new regional technique which was described by Forero et al in 2016. Several studies have demonstrated an effective role of ESPB in controlling pain for thoraco-abdominal surgeries which include breast surgery, thoracic surgery and upper GI laparoscopy. Shim et al in their study showed that ESPB significantly reduced pain score in first 6 hours postoperatively in patients who underwent VATS. The aim of this study is to evaluate the effect of ESPB using catheter on postoperative 24 hours opioid consumption in video-assisted thoracoscopy (VATS)
Circumcision is one of the most commonly performed operations in the pediatric population and is a painful procedure. Circumcision is performed with two popular techniques, Plastibell and conventional dissection method (CDM). For intra-operative (OP) and post-OP pain relief, two commonly used local anesthetic techniques are caudal block (CB) and dorsal penile block (DPNB) plus ring block (RB) at the base of the penis. There are very few randomized controlled trials comparing these two methods of intra-OP and post-OP pain relief, for different surgical techniques and there is a lack of well-conducted studies comparing the quality of analgesia, need for rescue analgesia in the early post-OP period, complications, and parental satisfaction comparing these blocks. Furthermore, there is a lot of contradiction in the literature regarding the duration of analgesia produced with these techniques.
Utilizing the Crosstalk Among Chicoric Acid, 13-Cis Retinoic Acid(Aerosolized), Minocycline and Vitamin D as a Potent Quadrate Therapy for treating patients with Multidrug-resistant TB and patient with both Multidrug-resistant TB and COVID-19 . A double-edged sword Clinical Study I)Part of Tuberculosis Tuberculosis (TB) is a major infectious disease killer globally. It affected 10 million and killed 1.4 million people in 2019 alone. The predicted impact of the COVID-19 pandemic is an additional 190,000 TB deaths in 2020, and it is expected in the next 5 y that there will be up to a 20% increase in the global TB disease burden , stressing the critical need for new safe and effective drugs against Mycobacterium tuberculosis (Mtb). In addition, controlling multidrug-resistant TB (MDR-TB) presents a huge public health challenge . New drug discovery could require several years with no guarantee but repurposing established may be useful to treat patients with tuberculosis . Here we demonstrate that we could utilize the crosstalk among Chicoric Acid, 13-Cis Retinoic Acid, Minocycline , and vitamin D as a novel quadrate therapy against TB.Drug-resistant tuberculosis represents a global emergency, requiring new drugs. Recently Minocycline was found to be highly potent in laboratory strains of Mycobacterium TB, and 30 drug-sensitive and multidrug/extensively drug-resistant clinical strains were susceptible to clinically attainable dosages. The lung concentration-time profiles of a 7 mg/kg/day human-equivalent minocycline dosage yielded bacterial kill rates comparable to first-line antituberculosis drugs. Extracellular bacilli were destroyed directly by minocycline. Minocycline also killed intracellular bacilli indirectly through granzyme A-driven apoptosis. Furthermore, minocycline showed dose-dependent antiinflammatory effect, suggesting that it may protect tuberculosis patients against immunopathology. A study showed that M. tuberculosis induced the expression of indoleamine 2,3-dioxygenase (IDO), an enzyme involved in tryptophan catabolism, in macrophages and in the lungs of animals (mice and macaque) with active disease. In a macaque model of inhalation TB, suppression of IDO activity reduced bacterial burden, pathology, and clinical signs of TB disease, leading to increased host survival. This increased protection was accompanied by increased lung T cell proliferation, induction of inducible bronchus-associated lymphoid tissue and correlates of bacterial killing . A recent study showed that Minocycline-induced significantly inhibition of IDO expression. But Minocycline-induced inhibition of IDO expression is retinoid-dependent. The combined treatment with minocycline and retinol, however, resulted in a striking, statistically significant decrease in IDO. Co-treatment with minocycline and retinol again resulted in decreased TNF-α and IL-6 levels. A study showed that IL-6 inhibits IFN-γ induced autophagy in Mycobacterium (TB) H37Rv infected macrophages. As well as neutralization of endogenous IL-6 by anti-IL-6 antibody significantly enhances the IFN-γ mediated killing of the intracellular bacteria. Minocycline's anti-inflammatory effects are mediated through RAR signaling. Therefore, The combined treatment with minocycline and retinol is expected to effectively inhibit (TB) and its inflammatory complication, Fortunately, Retinoic Acid significantly inhibits the in vivo growth of M. tuberculosis and the development of tuberculosis. In addition to, 13-Cis RA and Chicoric Acid ( CA ) enhanced the cell surface expression of HLA-DR and CD14 molecules on U937 macrophages and prevented the growth of Mtb within macrophages. Moreover, 13-cis RA and CA, have increased NO generation compared to untreated control macrophages, significantly . Both drugs have a significant inhibitory effect on Mtb growth but CA at the highest concentration was more potent than 13-cis RA . Therefore we will use retinoic acid to induce the effect of Minocycline as well as its ability to inhibit tuberculosis in combination with CA .Recent data showed that Vitamin D support innate immune responses to Mycobacterium TB and Low vitamin D levels were associated with a 5-fold increased risk for progression to tuberculosis. Deficiency of vitamin D has long been implicated in activation of (TB) . Serum vitamin D in TB patients are lower than in healthy controls . Vitamin D has been found to speed up the clearance of (TB) bacteria from the lungs of people with multi-drug resistant TB, according to a study of 1,850 patients. It was showed that Vitamin D receptor (VDR) must form a heterodimer complex with retinoid X receptor (RXR) to regulate gene transcription. Retinol plays a crucial role in lung development and signaling the vitamin D pathway. 9-cis-retinoic acid, an active vitamin A metabolite and the ligand of RXR, assists VDR signaling and suppresses the degradation of circulating vitamin D.
Observational Study of Infants Fed on DHA (Breast Source or Milk Formula Source ) and Its Effect on COVID-19 Severity - Amr kamel khalil Ahmed ( drmedahmed@gmail.com ) Director of tuberculosis program Ghubera, public health department ,First health cluster ,Ministry of health , Riyadh, Saudia Arabia https://orcid.org/0000-0003-3477-236X - Mahmoud Elkazzaz ( mahmoudramadan2051@yahoo.com ) Department of chemistry and biochemistry, Faculty of Science, Damietta University, Egypt https://orcid.org/0000-0003-3703-520X Abstract The novel SARS-CoV-2, which causes the disease called COVID-19, has rapidly spread across the globe. A striking and consistent observation has been the difference in severity of COVID-19 at different ages: severity, the need for hospitalization and mortality rise steeply with older age while severe disease and death are relatively rare in children and young adults. Most infants and children infected with SARS-CoV-2 are asymptomatic or have mild symptoms, most commonly fever, cough, pharyngitis, gastrointestinal symptoms and changes in sense of smell or taste. Whether infants and children are also less often infected by SARS-CoV-2 is an ongoing debate. Large epidemiological studies suggest that infants and children comprise only 1 to 2% of all SARS-CoV-2 cases. However, these numbers heavily depend on testing criteria and, in many reports, testing was done only in individuals who were symptomatic or required hospitalization, which is less often the case for children. Some studies suggest that infants and children are just as likely as adults to become infected with SARS-CoV-2.9 However, more recent studies report that children are less likely to get infected after contact with a SARS-CoV-2-positive individual.10-14 It has been suggested that children and adolescents have similar viral loads and may therefore be as likely to transmit SARS-CoV-2 as adults. In addition, the viral load may be similar in asymptomatic and symptomatic individuals. However, reassuringly, transmission in schools from children either to other children or to adults has been rare. The observation that children are less often infected with SARS-CoV-2 and that they have less severe symptoms is similar to that reported for SARS-CoV-1 and Middle East respiratory syndrome (MERS)-CoV. However, this pattern is strikingly different to that for infection with most other respiratory viruses (eg, respiratory syncytial virus (RSV), metapneumovirus, parainfluenza or influenza viruses), for which the prevalence and severity are both higher in children.Dr Amr kamel khalil Ahmed and Dr. Mahmoud Elkazzaz, the lead investigators of this observational study , recently published a preprint that demonstrated Docosahexaenoic acid (DHA) had a high binding affinity and greatest interactions with ACE2 active sites, as well as a moderate binding affinity and moderate interactions with the active sites of IL-6. The Docosahexaenoic acid (DHA) interacts with different active sites of IL6 and ACE2 which are involved in direct or indirect contacts with the ACE2 and IL-6 receptors which might act as potential blockers of functional ACE2 and IL-6 receptor complex. Docosahexaenoic acid (DHA) was detected in abundance in breast milk and other algal sources milk supplement used for newborns and children's feeding. As a result, we believe that docosahexaenoic acid (DHA) may protect children and newborns thorough competing with COVID-19 for ACE2 receptors and inhibiting IL-6 activity and may possibly help them avoid a cytokine storm and save their lives through inhibiting IL-6 and preventing SARS-CoV-2 RBD attachment to ACE2
Utilizing the crosstalk among aerosolized phenformin, methylene blue, photodynamic therapy , zinc and potassium for treating severe COVID-19 infection and its inflammatory complication Amr Ahmed(1), Mahmoud Elkazzaz(2), Tamer Haydara(3), and Abdullah Alkattan(4) 1.

Ministry of Health, Riyadh, Saudi Arabia. SARS-CoV-2 represents the largest current health challenge for the society. Moreover, numerous variants of the virus that causes COVID-19 are being tracked in the United States and globally during this pandemic. Here, we will use combination therapy which involve agents with significant activity and different mechanisms of action against covid-19 and its inflammatory complication. Excessive activities of cysteinyl cathepsins (CysCts) contribute to the progress of many diseases. however, therapeutic inhibition has been problematic. Cathepsin L are crucial in terms of the endocytosis by cleaving the spike protein, which permits viral membrane fusion with endosomal membrane, and succeeded by the releasing of viral genome to the host cell. Thereby, inhibition of cathepsin L may be advantageous in terms of decreasing infection caused by SARS-CoV-2. It is well known that zinc (Zn) possesses a variety of direct and indirect antiviral properties, which are realized through different mechanisms. Administration of Zn supplement has a potential to enhance antiviral immunity and to restore depleted immune cell function, in particular in immunocompromised patients. It has been found that Zn 2+ deficiency leads to an exaggerated activity of Cysteine cathepsin increasing the autoimmune/inflammatory response. . Zn2+ is a natural inhibitor of proteases with CysHis dyads or CysHis(Xaa) triads. cysteine protease Cathepsin L (CatL) involvement with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and COVID-19 from different points of view. At this purpose Zn 2+ metal can be safely combined with phenformin a drug that increases the anti-proteolytic effect of endogenous Zn 2+ lowering the excessive activity of some CysCts.; A study found that phenformin-Zn2+ complex is identified as a modifiable pharmacophore for synthesis of therapeutic CysCt inhibitors with a wide range of potencies and specificities. Phenformin stabilizes a "Zn2+ sandwich" between the drug and protease active site. Additionally, phenformin was found to be potent inhibitor of IL-6 R, with phenformin (100 µM) treatment for 48 h, decreased IL-6R expression in ANBL6, RPMI, U266, MM1S, and JJN3 was 5.51 (p = 0.0025), 3.03 (p = 0.0005), 1.55 (p < 0.05), 2.09 (p = 0.0082) and 1.19-fold, respectively. Furthermore, phenformin was discovered to potentially and strongly bind to ACE2 receptors, according to a docking research being conducted by the principle investigators of this clinical study therefore, Phenformin is expected to potentially attach to ACE2 receptors and lead to its downregulation, an inhibitory mechanism which may combat and block COVID-19 infection in lung epithelial cells. Phenformin may induce lactic acidosis therefore according to the principal investigator The phenformin will be utilized as aerosolized by inhalation for COVID-19 treatment and this may be an effective novel treatment strategy that would limit the risk of systemic side-effects associated with biguanides due to the low inhaled dose. In addition, we will use aerosolized phenformin in combination with methylene blue. A study found that a very marked improvement in lactate and pyruvate concentrations occurred within six hours of the beginning of méthylène blue administration in human . It has been known for some time that méthylène blue is a moderately efficient hydrogen acceptor in several enzyme sys¬ tems and significantly reduce oxidative stress by scavenging ROS. Moreover, Methylene Blue has antiviral activity and was found to Inhibit the Spike-ACE2 Protein-Protein Interaction-a Mechanism that can contribute to its Antiviral Activity Against COVID-19 For many reasons, methylene blue is a promising drug for an active treatment against SARS-CoV-2 . Since methylene blue can work as a photosensitizer, photodynamic therapy as an antiviral treatment has great potential in the treatment of COVID-19.. This clinical study will investigate the effectiveness of SARS-CoV-2 infected people treatment using methylene blue and the following photodynamic therapy after that our clinically approved patients will receive phenformin and zinc . But methylene blue may lead to lowering in potassium concentration.Therefore, we will add potassium supplement to this combination.

Director of tuberculosis program Ghubera, public health department ,First health cluster ,Ministry of health ,Saudia Arabia. - Very important Note: This clinical study is the first clinical study in literature (First posted August 12, 2021) which demonstrated depending on molecular findings that Vitamin A /Retinoic Acid will treat smell loss resulted by COVID-19 Recent rapidly accumulating evidences and reports indicate that partial loss of the sense of smell or even total anosmia are early markers of SARS-CoV-2 infection and frequently reported symptoms associated with the COVID-19 pandemic (Lechien J. R et al., 2020) However, the cellular mechanisms of this phenomenon are unknown. The rates of insomnia and depression were 26.45% and 9.92% in the COVID-19 patients after recovery. Therefore, finding an effective treatment for COVID-19 Anosmia is a critical point. Although, ACE2 has been identified as the principal host cell receptor of 2019-nCoV, and it is thought to play a critical role in the virus's entrance into the cell and subsequent infection, many cells can be infected by COVID-19 while also expressing little or no ACE2. Even though the COVID-19 entry receptor, angiotensin-converting enzyme 2 (ACE2), is not expressed in the receptor of olfactory neurons, or its synthesis is limited to to a minor fraction of these neurons.of these neurons, COVID-19 infection causes a loss of smell (anosmia) (Katarzyna Bilinska et al.,2021). Our recent findings showed that COVID-19 binds directly to STRA6 receptors of retinol leading to retinol depletion and retinoic acid insufficiency (M Elkazzaz et al,. 2021) . Retinoic acid insufficiency in the olfactory epithelium, both in mouse and chick models, causes progenitor cell maintenance failure and, consequently, olfactory neurons differentiation is not maintained . An explant system, showed that renewal of olfactory neurons is inhibited if retinoic acid synthesis was failed in the olfactory epithelium (Paschaki M et al., 2013) . It's worth noting that vitamin A shortage also causes olfactory and taste problems, In a study by Garrett-Laster et al., (1984), the patients had vitamin A deficiency because of malnutrition and alcoholic liver cirrhosis; they lost their sense of smell after that disorder. LaMantia and Rawson et al.,( 2007) reported that administration of retinoid acid after the damage of olfactory system motivates an immune response and produces a more quick recovery of olfactoryguided behavior. It was showed that Isotretinoin improved the significantly performance of patients in the olfactory test(Demet Kartal et al.,2017) Moreover, there is increasing evidence that retinoic acid (atRA) influences gene expression of components of renin-angiotensin system (RAS), which plays a pivotal role in the pathophysiology of essential hypertension. Retinoic acid induced ACE2 expression in different animal models. Moreover, a study suggests that topical retinoids may have applicability in promoting sinus regeneration and wound healing. In a study comparing treated and untreated nasal mucosa ,untreated regenerated mucosa showed expected changes of submucosal gland loss, basal lamina and lamina propria fibrosis and loss of cilia. Reinoic acid treatment appeared to result in better mucosal regeneration marked by less cellular atypia and fibrosis(Mendy S. Maccabee et al,. 2003).. Aerosolized retinoic acid will have an effective role in treating post COVID-19 anosmia (loss of smell) via upregulating ACE2, STRA 6 and regenerating of olfactory receptors and olfactory sensory cells and neurons.
